[0060] [0060] Figure 1 is a schematic diagram of a pagination occasion in a long term evolution system (Long Term Evolution, LTE). A paging table in the LTE system can include four pagination occasions. The duration of a time domain resource occupied by each paging occasion is a subframe. As shown in Figure 1, the distribution of the positions of the four pagination occasions is: subframe 0, subframe 4, subframe 5 and subframe 9. To be specific, a network device can send a paging message in each of subframe 0, subframe 4, subframe 5 and subframe 9. A terminal device can perform monitoring on the four subframes to obtain a paging message corresponding to the terminal device.
[0061] [0061] In a future wireless communications system, a beam-forming technology is used to confine the energy of a signal transmitted in a beam direction to improve the efficiency of signal reception. Beam-forming technology can effectively expand a transmission range of a radio signal and reduce signal interference, achieving greater communication efficiency and achieving greater network capacity.
[0062] [0062] A network device in a system applying beam forming technology can provide a plurality of beams simultaneously. Therefore, the network device needs to send a plurality of paging messages on one paging occasion, so that terminal devices located on different beams can receive corresponding paging messages. The plurality of paging messages at the paging occasion have consecutive time domain units, where each domain unit is used to send a paging message. The time domain unit can be a subframe.
[0063] [0063] For example, assuming that the network device can provide two beams simultaneously, on one paging occasion, the network device uses two consecutive subframes to send two paging messages. Apparently, a position of the paging occasion in the LTE system and a number of subframes included in each paging occasion are not suitable for sending a paging message in a system using beamforming technology.
[0064] [0064] Figure 2 is a schematic flowchart of a method for transmitting a paging message according to one embodiment of this request.
[0065] [0065] 201. A terminal device determines a target paging facility, where the target paging facility includes at least one of the following types of information: position information for a target paging occasion, position information for a target paging table and position information from a target monitoring window.
[0066] [0066] 202. The terminal device receives a target paging message at the target paging facility, where the target paging message is a paging message sent by a network device to the terminal device.
[0067] [0067] Figure 2 provides a method for receiving a paging message by the terminal device in a communications system that applies a beamforming technology.
[0068] [0068] The network device can send the paging message to the terminal device in a broadcast manner, or it can send the paging message directly to the terminal device. This is not limited to this type of order.
[0069] [0069] Optionally, in some modalities, the target paging feature includes the position information of the target paging occasion, the position information of the target paging occasion is an initial position of the target paging occasion in the paging frame, the frame pagination includes N pagination occasions, N pagination occasions are located in M time domain resources, and target pagination occasion is one of N pagination occasions, where N is a positive integer greater than or equal to 1 and M is a positive integer that is greater than or equal to 1 and less than or equal to N.
[0070] [0070] When M is equal to N, each PO is located in a time domain resource. For example, N = M = 4. A PO1 can be located in the first time domain resource, a PO2 can be located in the second time domain resource, a PO3 can be located in the third time domain resource and a PO 4 can be located in the fourth time domain resource.
[0071] [0071] When M is less than N, at least two POs use a time domain feature in a frequency division multiplexing manner. For example, N = 4 and M = 2. In this case, PO 1 and PO 2 can use the first time domain resource, and PO 3 and PO 4 can use the second time domain resource. For another example, PO 1, PO 2, PO 3 and PO 4 can use the same time domain feature in a time division multiplexing manner.
[0072] [0072] Each of the M time domain resources can include at least two time domain units.
[0073] [0073] For example, in some embodiments, the time domain unit may be a subframe. A number of subframes included in each of the M time domain resources is the same and each time domain resource can include at least two subframes.
[0074] [0074] For another example, in some modalities, the time domain unit may be a slot. The number of slots included in each of the M time domain resources is the same and each time domain resource can include at least two slots.
[0075] [0075] For another example, in some modalities, the time domain unit may be a mini-slot. A number of mini-slots included in each of the M time domain resources are the same and each time domain resource can include at least two mini-slots.
[0076] [0076] For another example, in some embodiments, the number of non-slot units included in each of the M time domain resources is the same and each time domain resource can include at least two non-slot units. The number of symbols included in any of the at least two non-slot units is the same.
[0077] [0077] To help a person skilled in the art to better understand the technical solutions of this application, some specific examples are provided in the description of this application. The specific examples are all described using an example in which the time domain unit is a slot or a subframe. Based on the specific examples, a person skilled in the art can also obtain an implementation in which the time domain unit is another unit, for example, a subframe, a mini-slot or a non-slot unit.
[0078] [0078] Optionally, in some modalities, a position of the target paging occasion in the paging table is related to at least one of a subcarrier spacing, a time domain position of a block of synchronization signals actually sent by the network and a time domain position of a block of candidate synchronization signals.
[0079] [0079] That a position of each of the M time domain resources in the paging frame is related to a subcarrier spacing it may be that the position of each time domain resource in the paging frame also varies when the subcarrier spacing is different.
[0080] [0080] For example, it is assumed that M is equal to 1 and that the time domain unit is a slot. When the subcarrier spacing is 15 kHz, a start position or the time domain position of the first time domain feature can be located in slot 5 on the paging frame. When the subcarrier spacing is 30 kHz, the start position or time domain position of the first time domain resource can be located in slot 10 on the paging frame. When the subcarrier spacing is 60 kHz, the start position or the time domain position of the first time domain resource can be located in slot 20 on the paging frame. When the subcarrier spacing is 120 kHz, the start position or the time domain position of the first time domain resource can be located in slot 40 on the paging frame.
[0081] [0081] That a position of each of the M time domain resources in the paging frame is related to an initial position of a set of signal synchronization bursts it may be that the initial position of the set of signal synchronization bursts is the same as an initial position of each time domain resource on the paging table.
[0082] [0082] For example, it is assumed that M is equal to 1 and that the time domain unit is a slot. When the subcarrier spacing is 15 kHz, the start position or time domain position of the first time domain resource and the start position of a set of signal sync bursts can both be located in slot 5 on the paging frame . When the subcarrier spacing is 30 kHz, the start position or time domain position of the first time domain resource and the start position of a set of signal sync bursts can both be located in slot 10 on the paging frame . When the subcarrier spacing is 60 kHz, the start position or time domain position of the first time domain resource and the start position of a set of signal sync bursts can both be located in slot 20 on the paging frame . When the subcarrier spacing is 120 kHz, the start position or time domain position of the first time domain resource and the start position of a set of signal sync bursts can both be located in slot 40 on the paging frame .
[0083] [0083] Optionally, in some modalities, the terminal device itself can determine information about the pagination occasion. Specifically, the terminal device can determine the starting position of the target paging occasion on the paging table based on a value of M.
[0084] [0084] Optionally, in some embodiments, the fact that the terminal device determines a position of a time domain resource of the target paging occasion in the paging table may be to determine a position of a first time domain unit in the time domain of the target paging occasion in the paging table. In other words, the fact that the terminal device determines a position of a time domain resource of the target paging occasion in the paging table may be determining an initial position of the time domain resource of the target paging occasion in the paging table . A number of time domain units included in each of the time domain resources are known to the terminal device. In other words, a length of each time domain resource is known on the terminal device. Therefore, after determining the position of the first time domain unit in the time domain resource of the target paging occasion in the paging frame, the terminal device can determine a specific position of the time domain resource of the target paging occasion in the frame pagination.
[0085] [0085] Optionally, in some modalities, M = 1. In this case, only a time domain resource is included. In this case, the starting position of the target paging occasion in the paging frame is the time domain unit 0 in the paging frame.
[0086] [0086] Optionally, in other modalities, M = 1, and the starting position of the target paging occasion in the paging table is the time domain unit K1 / 2 in the paging table. K1 is a positive integer and K can be exactly divided by 2.
[0087] [0087] It can be understood that a value of K1 should not be more than twice the number of time domain units included in a paging table.
[0088] [0088] For example, when the subcarrier spacing is 15 kHz, the number of slots included in a frame is 10. To be specific, the paging frame can include slot 0 to slot 9. In this case, the target home position of the paging occasion in the paging frame can be any one from slot 1 to slot 9 in the paging frame.
[0089] [0089] For another example, when the subcarrier spacing is 30 kHz, the number of slots included in a frame is 20. To be specific, the paging frame can include slot 0 to slot 19. In this case, the starting position of the target paging occasion in the paging frame can be any one from slot 1 to slot 19 in the paging frame.
[0090] [0090] For another example, when the subcarrier spacing is 60 kHz, the number of slots included in a frame is 40. To be specific, the paging frame can include slot 0 to slot 39. In this case, the starting position of the target paging occasion in the paging frame can be any one from slot 1 to slot 39 in the paging frame.
[0091] [0091] For another example, when the subcarrier spacing is 120 kHz, the number of slots included in a frame is 80. To be specific, the paging frame can include slot 0 to slot 79. In this case, the starting position of the target paging occasion in the paging frame can be any one from slot 0 to slot 79 in the paging frame.
[0092] [0092] Optionally, in some modalities, K1 is a number of time domain units included in a paging table. For example, the time domain unit is assumed to be a slot. When the subcarrier spacing is 15 kHz, the starting position of the target paging occasion in the paging frame can be slot 5 in the paging frame. When the subcarrier spacing is 30 kHz, the starting position of the target paging occasion in the paging frame can be slot 10 in the paging frame. When the subcarrier spacing is 60 kHz, the starting position of the target paging occasion in the paging frame can be slot 20 in the paging frame. When the subcarrier spacing is 120 kHz, the starting position of the target paging occasion in the paging frame can be slot 40 in the paging frame.
[0093] [0093] It can be understood that slot x in this modality of this order can also be referred to as slot x, and indicates a slot whose slot index is x (x is a positive integer greater than or equal to 0). For example, slot 0 can also be referred to as slot 0 and indicates a slot whose index is 0; and slot 5 can also be referred to as slot 5 and indicates a slot whose index is 5. Likewise, the time domain unit x in this embodiment of this order can also be referred to as time domain unit x, and indicates a time domain unit whose index is x; subframe x can also be referred to as subframe x, and indicates a subframe whose subframe index is x; mini-slot x can also be referred to as mini-slot x, and indicates a mini-slot whose index of mini-slot is x; and a non-slot drive x can also be referred to as a non-slot drive x, and indicates a non-slot drive whose non-slot drive index is x.
[0094] [0094] It can be understood that slot x in the paging frame is the (x + 1) -th slot in the paging frame. For example, slot 0 in the paging frame is the first slot in the paging frame and slot 5 in the paging frame is the sixth slot in the paging frame. Likewise, the time domain unit x in the paging table is the (x + 1) -th time time domain unit in the paging table; subframe x in the paging frame is the (x + 1) -th subframe in the paging frame; mini-slot x in the paging frame is the (x + 1) -th mini-slot in the paging frame; and the non-slot unit x in the paging frame is the (x + 1) -th non-slot unit in the paging frame.
[0095] [0095] Optionally, in some modalities M = 1, and the starting position of the target paging occasion in the paging table can be a time domain unit to receive a block of synchronization signals in the paging table by the terminal device. In other words, the PO and the block of synchronization signals can use the same time domain unit. This can reduce the occupation of time domain resources by the PO. In this way, a time-saving resource can be used to transmit other information.
[0096] [0096] Optionally, in some modalities M = 1, and the starting position of the target paging occasion in the paging table can be a time domain unit next to a time domain unit to receive a last block of synchronization signals in the paging table by the terminal device. For example, the time domain unit is a slot. The subcarrier spacing is assumed to be 15 kHz. If the last block of synchronization signals received by the terminal device is located in slot 6, the first time domain unit will be slot 7.
[0097] [0097] The terminal device can determine the time domain position of the candidate SSB and the time domain position of the SSB actually transmitted based on the SSB position indication information sent by the network device. It can be understood that the SSB actually transmitted is an SSB actually sent by the network device. The candidate SSB can also be referred to as a broadcastable SSB. The terminal device can receive the SSB at the position where the candidate SSB is located. The SSB actually transmitted can also be referred to as received SSB. The terminal device finally receives the SSB in the domain position at the time the network device actually sends the SSB.
[0098] [0098] The network device can indicate the position of the SSB using bitmap information from RMSI.
[0099] [0099] For example, for a frequency band greater than 6 GHz, a set of signal synchronization bursts has a maximum of 64 SSBs. The 64 SSBs can be grouped into eight groups. The network device can use 8-bit information to indicate whether each group of SSBs is sent. Each group of SSBs can include eight SSBs. The network device can use 8-bit information to indicate whether the eight SSBs were sent. The states on whether SSBs in each group of SSBs are sent are consistent. Therefore, the network device can use SSB position indication information whose length is 16 bits to indicate the time domain unit position to transmit the SSB and the time domain unit position of the actually transmitted SSB. For example, the SSB position indication information is 1101100110100011. The first eight bits in the 16 bits can indicate group information. The group information is 11011001, which can indicate that the SSBs of a group 0, a group 1, a group 3, a group 4 and a group 7 are actually sent. The last eight bits in the 16 bits can indicate intragroup information. The intragroup information is 10100011, which indicates that SSBs 0, 2, 6 and 7 in a group are sent.
[00100] [00100] The terminal device can determine two types of SSBs, where one type is an SSB actually sent by the network device and the other type is a candidate SSB. Still using 1101100110100011 as an example of the SSB position indication information, the SSBs actually sent by the network device are SSBs 0, 2, 6 and 7 in groups 0, 1, 3, 4 and 7. Candidate SSBs are all SSBs in groups 0 to 7.
[00101] [00101] The network device can also send a time index from the SSB to the terminal device. The SSB time index is used to indicate the time domain resource position that can be used by the network device to send the SSB. In this way, the terminal device determines, based on the SSB time index and SSB position indication information, the domain resource position of the SSB time actually sent by the network device and the domain resource position of the candidate SSB time.
[00102] [00102] Optionally, in some modalities, M is equal to 2, the initial position of the first of the M time domain resources can be the time domain unit 0 in the paging table, and an initial position of the second of the M resources time domain can be the time domain unit K2 / 2 in the paging table, where K2 is a positive integer greater than 2 and can be exactly divided by 2. Optionally, in some modalities, a time domain resource in that the target paging occasion is located can be the first time domain resource. Optionally, in other modalities, a time domain resource on which the target paging occasion is located can be the second time domain resource. In other words, the starting position of the target paging occasion in the paging table can be the starting position of the first time-domain resource or the starting position of the second time-domain resource. To be more specific, the starting position of the target paging occasion in the paging table is the time domain unit 0 in the paging table or the time domain unit K2 / 2 in the paging table.
[00103] [00103] Similar to K1, a value of K2 should not be more than twice the number of time domain units included in a paging table.
[00104] [00104] Optionally, in some embodiments, M is equal to 2, at least one time domain unit can be included between a first time domain unit in the first of the time domain M resources and a first time domain unit time in the second of the M time domain resources.
[00105] [00105] Using 15 kHz subcarrier spacing as an example, when the start position or time domain position of the first time domain resource is slot 0, the start position or time domain position of the second resource time domain can be any one of slots 2 through 8. It can be understood that if the first time domain unit in the second time domain resource is slot 9, when the next subframe is also a paging frame, the starting positions or time domain positions of two time domain units in different paging tables can be consecutive. Likewise, when the start position or time domain position of the first time domain resource is slot 1, the start position or time domain position of the second time domain resource can be any of the slots. 3 to 8. Likewise, when the start position or time domain position of the first time domain resource is slot 2, the start position or time domain position of the second time domain resource can be any of slots 4 through 8. Likewise, when the start position or time domain position of the first time domain resource is slot 3, the start position or time domain position of the second domain resource time can be any one of slots 5 through 8. Likewise, when the start position or time domain position of the first time domain resource is slot 4, the start position or time domain position of the second time domain resource can be any uer one of the slots numbered 6 through 8. Likewise, when the start position of the first time domain resource is slot 5, the start position or time domain position of the second time domain resource can be a numbered slots 7 and 8. Likewise, when the start position or time domain position of the first time domain resource is slot 6, the start position or time domain position of the second time domain resource time may be slot 8.
[00106] [00106] A person skilled in the art can understand that specific implementations in which the subcarrier spacing is 30 kHz, 60 kHz or 120 kHz are similar to the implementation in which the subcarrier spacing is 15 kHz. To avoid repetition, the details are not described here.
[00107] [00107] Optionally, in some modalities, K2 is a number of time domain units included in a paging table. For example, the time domain unit is assumed to be a slot. When the subcarrier spacing is 15 kHz, the start position or time domain position of the first time domain resource can be located in slot 0 on the paging frame, and the start position or time domain position of the second time domain. time domain resource can be located in slot 5 on the paging frame. When the subcarrier spacing is 30 kHz, the start position or time domain position of the first time domain feature can be located in slot 0 on the paging frame, and the start position or time domain position of the second time domain. time domain resource can be located in slot 10 on the paging frame. When the subcarrier spacing is 60 kHz, the start position or time domain position of the first time domain feature can be located in slot 0 on the paging frame, and the start position or time domain position of the second time domain. time domain resource can be located in slot 20 on the paging frame. When the subcarrier spacing is 120 kHz, the start position or time domain position of the first time domain feature can be located in slot 0 on the paging frame, and the start position or time domain position of the second time domain resource can be located in slot 40 on the paging frame.
[00108] [00108] Optionally, in some embodiments, M is equal to 4, and the terminal device determines that the start position or time domain position of the first of the time domain M resources is the time domain unit 0 in the frame of paging, the starting position or the time domain position of the second of the M time domain resources is the K2 / 4 time domain unit in the paging frame, a starting position or the time domain position of the third of the M time domain resources is the K2 / 2 time domain unit in the paging frame, and a starting position or time domain position of the quarter of the M time domain resources is the time domain unit in the frame. pagination.
[00109] [00109] At least one time domain unit can be included between the starting positions of two adjacent time domain resources in the M time domain resources, or the starting positions of two adjacent time domain resources can be separated by at least one time domain unit, similar to the case where M is equal to 2.
[00110] [00110] Using 15 kHz subcarrier spacing as an example, when the start position or time domain position of the first time domain resource is slot 0, the start position or time domain position of the second resource time domain can be slot 2, the start position or time domain position of the third time domain resource can be slot 4, and the start position or time domain position of the fourth time domain resource time can be any of slots 6 through 8.

[00116] [00116] Still using 15 kHz subcarrier spacing as an example, when the start position or time domain position of the first time domain resource is slot 1, the start position or the time domain position of the second time domain resource can be slot 4, the start position or time domain position of the third time domain resource can be slot 6, and the start position or time domain position of the fourth domain resource of time can be slot 8.

[00119] [00119] Optionally, in some modalities, K2 is a number of time domain units included in a paging table.

The start positions or time domain positions of the remainder of the four time domain resources can be located in separate positions from the first time domain unit in the previous two time domain resources by a plurality of time domain units. This can facilitate the use of a time domain unit with an SSB in a time division multiplexing manner.
[00124] [00124] It can be understood that starting positions or time domain positions of only two of the four time domain resources need to be the time domain unit 0 and the time domain unit K ’/ 2, respectively.

Table 10 PO 0 PO 1 PO 2 PO 3 PO 0 PO 1 PO 2 PO 3 PO 0 PO 1 PO 2 PO 3 0 8 16 24 0 9 17 29 0 11 19 31 0 8 16 25 0 9 17 30 0 11 19 32 0 8 16 26 0 9 17 31 1 9 17 25 0 8 16 27 0 9 17 32 1 9 17 26 0 8 16 28 0 9 18 26 1 9 17 27 0 8 16 29 0 9 18 27 1 9 17 28 0 8 16 30 0 9 18 28 1 9 17 29 0 8 16 31 0 9 18 29 1 9 17 30 0 8 16 32 0 9 18 30 1 9 17 31 0 8 17 25 0 9 18 31 1 9 17 32 0 8 17 26 0 9 18 32 1 9 18 26 0 8 17 27 0 9 19 27 1 9 18 27 0 8 17 28 0 9 19 28 1 9 18 28 0 8 17 29 0 9 19 29 1 9 18 29 0 8 17 30 0 9 19 30 1 9 18 30 0 8 17 31 0 9 19 31 1 9 18 31
[00151] [00151] In Table 10 and Table 11, PO 0 indicates a slot index of a position of the first of the four paging features in the paging frame, PO 1 indicates a slot index of a position of the second of the four features of paging in the paging frame, PO 3 indicates a slot index of a position of the third of the four paging features in the paging frame and PO 4 indicates a slot index of a position of the fourth of the four paging features in the frame pagination.
[00152] [00152] Table 12 and Table 13 show slot-based time domain resource positions when a paging frame includes two time domain resources and the subcarrier spacing is 60 kHz.
[00153] [00153] In Table 12 and Table 13, PO 0 indicates a slot index of a position of the first of the two paging features in the paging frame, and PO 1 indicates a slot index of a position of the second of the two features pagination in the pagination table.
[00154] [00154] Table 14 to Table 20 shows the positions of slot-based time domain resources when a paging frame includes two time domain resources and the subcarrier spacing is 120 kHz. Table 14
[00155] [00155] In Table 14 to Table 20, PO 0 indicates a slot index of a position of the first of the two paging features in the paging table, and PO 1 indicates a slot index of a position of the second of the two features pagination in the pagination table.
[00156] [00156] Furthermore, in the previous modality, the terminal device can directly determine a location of the initial position or the time domain position of the target paging occasion in the paging table. The number of time domain units included in each of the time domain resources is known by the terminal device. Therefore, in other embodiments, the terminal device can also determine a position of any time domain unit in each time domain resource on the paging table. In this way, the terminal device can indirectly determine the location of the starting position or the time domain position of the target paging occasion in the paging table.
[00157] [00157] The 15 kHz subcarrier spacing is used as an example. M is equal to 1. Each time domain resource is assumed to include three time domain units. Each time domain unit is a slot. If the terminal device determines that a second time domain unit in the time domain resource is slot 1, the terminal device can determine that the starting position of the target paging occasion is slot 0.
[00158] [00158] Optionally, in some modalities, the positions of the M time domain resources can also be related to a half-frame indication. When the terminal device itself determines the start position or time domain position of the target paging occasion on the paging table, the terminal device can also determine the start position or time domain position of the target paging occasion on the paging table. paging based on the half-frame indication sent by the network device. The half-frame indication is used to indicate the position of an SSB or a set of bursts of sync signal.
[00159] [00159] Optionally, in some modalities, the positions of the M time domain resources can also be related to an indication of multiplexing by frequency division of the paging message and the SS block. When the terminal device itself determines the start position or time domain position of the target paging occasion on the paging table, the terminal device can also determine the start position or time domain position of the target paging occasion on the paging table. pagination based on the indication of frequency division multiplexing sent by the network device.
[00160] [00160] For example, if the half frame indication is 0, an initial position of the SSB or the set of bursts of synchronization signal will be in the second half frame of the paging frame. Correspondingly, the starting position or the time domain position of the target paging occasion in the paging frame may be located in the second half frame. For another example, if the half frame indication is 1, an SSB start position or set of burst bursts will be in the first half frame of the paging frame. Correspondingly, the starting position or the time domain position of the target paging occasion in the paging frame may be located in the first half frame.
[00161] [00161] For example, if the half-frame indication is 0, the initial position of the SSB or the set of bursts of synchronization signal in the first half-frame of the paging frame. Correspondingly, the starting position or the time domain position of the target paging occasion in the paging frame may be located in the first half frame. For another example, if the half frame indication is 1, the SSB start position or set of burst bursts will be in the second half frame of the paging frame. Correspondingly, the starting position or the time domain position of the target paging occasion in the paging frame can be located in the second half frame.
[00162] [00162] Optionally, in some modalities, when there is a plurality of pagination occasions in a pagination frame, an index of a PO in the frequency division multiplexing with an SSB in the frame can be predefined. For example, the first PO in frequency division multiplexing with the SSB in the frame can be defined; the second PO in frequency division multiplexing with the SSB in the frame can be defined; the third PO in frequency division multiplexing with the SSB in the frame can be defined; or the fourth PO in frequency division multiplexing with the SSB in the frame can be defined. In addition, the definition can be based on an SSB position. For example, when the SSB is in the first half frame, and the number of POs is 4, the first PO whose index is 0 or the second PO whose index is 1 can be defined as a PO in multiplexing by frequency division with the SSB; or when the SSB is in the second half frame, and the number of POs is 4, the third PO whose index is 2 or the fourth PO whose index is 3 can be defined as a PO in multiplexing by frequency division with the SSB. When the number of POs in the table is 2, the first PO whose index is 0 or the second PO whose index is 1 can be defined as a PO in multiplexing by frequency division with the SSB. In addition, the definition can be based on the position of the SSB. For example, when the SSB is in the first half frame, the first PO whose index is 0 can be defined as a PO in frequency division multiplexing with the SSB. For example, when the SSB is in the second half-frame, the second PO whose index is 1 can be defined as a PO in frequency division multiplexing with the SSB.
[00163] [00163] Optionally, in some modalities, when the initial position or time domain position of the target paging occasion in the paging frame is in the first half frame, the initial position or time domain position of the paging occasion target in the paging frame can start from subframe 0 (for example, it can be subframe 0). When the start position or time domain position of the target paging occasion in the paging frame is in the second half frame, the start position or time domain position of the target paging occasion in the paging frame can start from of subframe 5 (for example, it can be subframe 5). Optionally, in other modalities, when the subcarrier spacing is 15 kHz, when the starting position or the time domain position of the target paging occasion in the paging frame is in the first half frame, the starting position or the dominance position the time of the target paging occasion in the paging frame can start from slot 0 (for example, it can be slot 0); or when the start position or time domain position of the target paging occasion in the paging frame is in the second half frame, the start position or time domain position of the target paging occasion in the paging frame may begin to from slot 5 (for example, it can be slot 5). When the subcarrier spacing is 30 kHz, when the starting position or the time domain position of the target paging occasion in the paging frame is in the first half frame, the starting position or time domain position of the paging occasion target in the paging frame can start from slot 0 (for example, it can be slot 0); or when the start position or time domain position of the target paging occasion in the paging frame is in the second half frame, the start positions of the M time domain features can start from slot 10 (for example, you can be slot 10). When the subcarrier spacing is 60 kHz, when the start position or time domain position of the target paging occasion in the paging frame is in the first half frame, the start position or time domain position of the paging occasion target in the paging frame can start from slot 0 (for example, it can be slot 0); or when the start position or time domain position of the target paging occasion in the paging frame is in the second half frame, the start positions of the M time domain resources can start from slot 20 (for example, can be slot 20). When the subcarrier spacing is 120 kHz, when the start position or time domain position of the target paging occasion in the paging frame is in the first half frame, the start position or time domain position of the paging occasion target in the paging frame can start from slot 0 (for example, it can be slot 0); or when the start position or time domain position of the target paging occasion in the paging frame is in the second half frame, the start position or time domain position of the target paging occasion in the paging frame may begin to from slot 40 (for example, it can be slot 40).
[00164] [00164] Certainly, the starting position or the time domain position of the target paging occasion in the paging table can also start from other subframes, and is not related to the indication of half frame.
[00165] [00165] Optionally, in some modalities, when a period of the set of bursts of synchronization signal in the system is 5 ms, the starting position or the time domain position of the target paging occasion in the paging table can start from the subframe 0 (for example, it can be subframe 0), or the starting position or time domain position of the target paging occasion in the paging frame can start from subframe 5 (for example, it can be subframe 5) . Optionally, in other modalities, when the subcarrier spacing is 15 kHz, the start position or time domain position of the target paging occasion in the paging frame can start from slot 0 (for example, it can be slot 0 ), or the start position or time domain position of the target paging occasion in the paging table can start from slot 5 (for example, it can be slot 5). When the subcarrier spacing is 30 kHz, the start position or time domain position of the target paging occasion in the paging frame can start from slot 0 (for example, it can be slot 0), or the starting positions of the M time domain resources can start from slot 10 (for example, it can be slot 10). When the subcarrier spacing is 60 kHz, the starting position or the time domain position of the target paging occasion in the paging frame can start from slot 0 (for example, it can be slot 0), or the starting positions of the M time domain resources can start from slot 20 (for example, it can be slot 20). When the subcarrier spacing is 120 kHz, the starting position or the time domain position of the target paging occasion in the paging frame can start from slot 0 (for example, it can be slot 0), or the starting position or the time domain position of the target paging occasion in the paging table can start from slot 40 (for example, it can be slot 40).
[00166] [00166] Using the half-frame indication, the terminal device can also determine the starting position of the SSB or burst of sync signal, and the PO can use the same time domain feature as the SSB or the burst set. bursts of synchronization signal in a time division multiplexing manner.
[00167] [00167] Optionally, in other modalities, the terminal device can also determine the starting position or the duration of the target paging occasion in the paging table based on the paging position information sent by the network device. Paging position information is used to indicate the time domain position of the target paging occasion in the paging table.
[00168] [00168] The paging position information is related to at least one of the subcarrier spacing, the time domain position of the synchronization signal block actually sent by the network device, and the time domain position of the signal block candidate synchronization; or, in other words, the time domain positions of the time domain resources in the paging frame are related to at least one subcarrier spacing, the time domain position of the block of synchronization signals actually sent by the network, and the time domain position of the candidate sync signal block.
[00169] [00169] Optionally, in some modalities, the paging position information may include a location of the initial position of the first of the M time domain resources in the paging table. When M is a positive integer greater than 1, the quantities of time domain units included in any two of the time domain resources are equal. In other words, the paging position information can indicate, by indicating the time domain positions of the time domain resources in the paging table, the time domain position of the target paging occasion in the paging table.
[00170] [00170] Optionally, in some modalities, the value of M and the number of time domain units included in each of the time domain M resources are known by the terminal device.
[00171] [00171] Optionally, in some modalities, the specific time domain position of the target paging occasion in the M time domain positions is also known by the terminal device.
[00172] [00172] The "known" in this application may be that the configuration information is previously notified to the terminal device by the network device, or the information is agreed upon by the network device and the terminal device, or specified in a protocol, or derived by terminal device based on a configuration parameter.
[00173] [00173] Optionally, in other modalities, the value of M and a total length of the M time domain resources are known by the terminal device. In this way, the terminal device can determine, based on the value of M and the total length of the M time domain resources, the number of time domain units included in each time domain resource.
[00174] [00174] When M is equal to 1, the paging position information is the starting position of the target paging occasion in the paging table. The terminal device can directly determine the starting position of the target paging occasion in the paging table based on the paging position information.
[00175] [00175] When M is equal to 2 or equal to 4, when the terminal device determines the initial position of the first time domain resource in the paging frame, the terminal device can determine the initial position of the target paging occasion in the pagination based on the time domain resource on which the target paging occasion is located.
[00176] [00176] Optionally, in some modalities, the M time domain resources can be consecutive time domain resources. In this way, when the location of the starting position of the first time domain resource on the paging table is determined, the terminal device can determine a location of the starting position of each time domain resource on the paging table using the following formula: POi _ s  O  i _ s  Length _ PO Formula 1.1 where POi_s indicates a location of an initial position of a time domain resource whose index is i_s in the paging frame, O indicates the location of the initial position of the first resource of time domain in the paging table, i_s is an index of a time domain resource, and Length_PO is a number of time domain units included in a time domain resource. An index of the mth time domain resource of the M time domain resources is m- 1, where m = 1, ..., M. For example, an index of the first time domain resource is 0, one index of the second time domain resource is 1, an index of the third time domain resource is 2 and an index in the fourth time domain resource is 3. It can be understood that if i_s in Formula 1.1 is an index of the resource time domain in which the target paging occasion is located, the terminal device can directly determine the position of the target paging occasion on the paging table using Formula 1.1.
[00177] [00177] The 15 kHz subcarrier spacing is used as an example. It is assumed that M is equal to 2 and that each time domain resource includes two time domain units. The two time domain resources are consecutive time domain resources. The pagination position information is assumed to indicate that the initial position of the first time domain resource is slot 0. According to Formula 1.1, O is equal to 0, Length_PO is equal to 2, and i_s is equal a 1. This way, the terminal device can determine that the starting position of the second time domain resource is slot 2.
[00178] [00178] Optionally, in other modalities, the M time domain resources can be M non-consecutive time domain resources. M non-consecutive time domain resources are M time domain resources in P consecutive time domain resources. Other time domain resources in the P consecutive time domain resources in addition to the M time domain resources have been determined to transmit information other than a paging message. Information other than the paging message can be uplink information or other downlink information (for example, an SSB). P is a positive integer greater than M.
[00179] [00179] Thus, when the location of the initial position of the first time domain resource in the paging table is determined, the terminal device can determine a location of the initial position of each time domain resource in the paging table using the following formula: POi _ s  O  i _ s  Length _ PO  Length _ offset i _s Formula 1.2 where POi_s indicates a location of an initial position of a time domain resource whose index is i_s in the paging frame, O indicates the location of the starting position of the first time domain resource in the paging frame, i_s is an index of a time domain resource, Length_PO is the number of time domain units included in a time domain resource, and Length_offseti_s indicates a number of time domain units that are between the starting position of the time domain resource whose index is i_s and a time domain resource whose index is i_s - 1 and are used to transmit r other information. It can be understood that, if i_s in Formula 1.2 is an index of the time domain resource on which the target paging occasion is located, the terminal device can directly determine the position of the target paging occasion on the paging table using Formula 1.2 .
[00180] [00180] The 15 kHz subcarrier spacing is still used as an example. It is assumed that M is equal to 2, and that each time domain resource includes two time domain units. The terminal device determined that slot 2 to slot 5 is used to transmit information other than a paging message. The pagination position information is assumed to indicate that the starting position of the first time domain resource is slot 0. According to Formula 1.2, O is equal to 0, Length_PO is equal to 2, and Length_offseti_s is equal a 4. In this way, the terminal device can determine that the starting position of the second time domain resource is slot 6.
[00181] [00181] Optionally, in some modalities, the paging position information may include the total length of the M time domain resources. In addition, the location of the start position or the time domain position of the first time domain resource is known to the terminal device. In addition, when M is a positive integer greater than 1, the quantities of time domain units included in any two of the time domain M resources are equal.
[00182] [00182] Optionally, in some modalities, the value of M is known in the terminal device. In this way, the terminal device can determine, based on the total length of the M time domain resources and the M value, the number of time domain units included in each time domain resource. In this case, the starting positions or time domain positions of the time domain resources, the number of time domain units included in each time domain resource, and the indexes of the time domain resources are all known by terminal device. When the M time domain resources are consecutive M time domain resources, the terminal device can determine the time domain position of the target paging occasion on the paging table using Formula 1.1. When the M time domain resources are consecutive M time domain resources, the terminal device can determine the time domain position of the target paging occasion on the paging table using Formula 1.2.
[00183] [00183] Optionally, in other modalities, the number of time domain units included in each of the time domain M resources is known by the terminal device. In this way, the terminal device can determine an index of each time domain resource based on the total length of the time domain M resources and the number of time domain units included in each of the time domain M resources. In this case, the starting positions or time domain positions of the time domain resources, the number of time domain units included in each time domain resource and the indexes of the time domain resources are all known by the device terminal. When the M time domain resources are consecutive M time domain resources, the terminal device can determine the time domain position of the target paging occasion on the paging table using Formula 1.1. When the M time domain resources are consecutive M time domain resources, the terminal device can determine the time domain position of the target paging occasion on the paging table using Formula 1.2.
[00184] [00184] Optionally, in some embodiments, the paging position information may include the total length of the M time domain resources and the location of the starting position or the time domain position of the first of the M time domain resources in the paging table. The value of M or the number of time domain units included in each time domain resource is known to the terminal device. In addition, when M is a positive integer greater than 1, the quantities of time domain units included in any two of the time domain M resources are equal.
[00185] [00185] In this case, the terminal device can determine the initial positions of the M time domain resources, the number of time domain units included in each of the M time domain resources and the indexes of the time domain resources . When the M time domain resources are consecutive M time domain resources, the terminal device can determine the time domain position of the target paging occasion on the paging table using Formula 1.1. When the M time domain resources are consecutive M time domain resources, the terminal device can determine the time domain position of the target paging occasion on the paging table using Formula 1.2.
[00186] [00186] When the paging position information includes the total length of the M time domain resources and / or the location of the initial position of the first of the M time domain resources in the paging table, the network device can indicate the positions of the M time domain resources in the paging frame using fewer bits.
[00187] [00187] Optionally, in other modalities, the paging position information may include the location of the initial position or the time domain position of each of the M time domain resources in the paging table. In this way, the terminal device can directly determine the position of each time domain resource on the paging table, without calculating the position of each time domain resource on the paging table alone. In this case, the configured position of the pagination occasion in the paging table can be determined based on a number of pagination occasions in a discontinuous reception cycle. For example, when the number of paging occasions is 4, k1 bits are needed to indicate a position for each PO, where k1 is a positive integer greater than or equal to 1. A value of k1 is related to subcarrier spacing. When the number of paging occasions is 4, the paging position information can include 4 * k1 bits (* indicates a multiplication sign). For example, if the subcarrier spacing is 15 kHz, the k1 value can be 2 bits; or if the subcarrier spacing is 30 kHz, the k1 value can be 3 or 4. When the subcarrier spacing is 60 kHz or 120 kHz, the k1 value can be 3 or 4.
[00188] [00188] It can be understood that, a length of the paging position information is related to a maximum number of candidate positions for an initial position or the time domain position of each slot in the paging table, and the value of M.
[00189] [00189] The 15 kHz subcarrier spacing is used as an example. The value of M is assumed to be 4.
[00190] [00190] Optionally, in some embodiments, the start position or time domain position of the first time domain resource can be slot 0 to slot 6. The start position or time domain position of the second domain resource time slot can be located in slot 1 through slot 7. The start position or time domain position of the third time domain feature can be located in slot 2 at slot 8. The start position or time domain position of the fourth time domain resource can be located in slot 2 to slot 8. As can be seen, in the paging table, there are six candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource in the paging table can be indicated using three bits.
[00191] [00191] Optionally, in other modalities, the start position or time domain position of the first time domain resource can be located in slot 0 to slot 3. The start position or time domain position of the second time resource time domain can be located in slot 2 to slot 5. The start position or time domain position of the third time domain resource can be located in slot 4 to slot 7. The start position or time domain position from the fourth time domain resource can be located in slot 5 to slot 8. As can be seen, in the paging table, there are four candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource on the paging table can be indicated using two bits.
[00192] [00192] Optionally, in some modalities, the position of each of the M time domain resources can also be related to the indication of half frame. In other words, the location of the starting position or the time domain position of each of the M time domain resources in the paging frame can be indicated using the half frame indication and a specific position indication together.
[00193] [00193] For example, in some modalities, the paging position information can include three bits. The first of the three bits is the half-frame indication. The half frame indication is used to indicate that the start position or time domain position of the time domain feature is located in the first half frame or the second half frame, and the last two of the three bits are the specific position indication. The specific position indication can be used to indicate a specific time domain unit of a half frame in which the start position or the time domain position of the time domain resource is located.
[00194] [00194] Optionally, in some modalities, the half-frame indication and the specific position indication can be a plurality of consecutive bits. In other words, the network device can use a message to carry the half-frame indication and the specific position indication.
[00195] [00195] Optionally, in other modalities, the indication of half-frame and the indication of specific position can be indicated to the terminal device separately. In other words, the network device can indicate the half-frame indication and the specific position indication for the terminal device using two messages.
[00196] [00196] Specifically, if the half frame indication is 0, the indicated time domain start position or time domain position is located in the first half frame of the paging frame, that is, slot 0 slot 4; or if the half frame indication is 1, the start position or the time domain indicated position of the time domain feature is located in the second half frame of the paging frame, that is, slot 5 to slot 9. If the position indication is 00, the start position or indicated time domain position of the time domain feature is located in the first slot; if the specific position indication is 01, the start position or the indicated time domain position of the time domain resource is located in the second slot; if the specific position indication is 10, the starting position or indicated time domain position of the time domain feature is located in the third slot; or if the specific position indication is 11, the starting position or indicated time domain position of the time domain feature is located in the fourth slot.
[00197] [00197] For example, if the paging position information is 010, the starting position or the indicated time domain position of the time domain resource is the third slot in the first half frame, that is, slot 2. For another example, if the paging position information is 110, the starting position or indicated time domain position of the time domain feature is the third slot in the second half frame, that is, slot 7.
[00198] [00198] The 15 kHz subcarrier spacing is still used as an example. The value of M is assumed to be 2.
[00199] [00199] Optionally, in some embodiments, the start position or time domain position of the first time domain resource can be slot 0 to slot 8, and the start position or time domain position of the second time resource time domain can be from slot 2 to slot 8. As can be seen, in the pagination table, there are a maximum of nine candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource on the paging table can be indicated using four bits.
[00200] [00200] Optionally, in other modalities, the start position or time domain position of the first time domain resource can be slot 0 to slot 3. The start position or time domain position of the second domain resource can be located in slot 5 through slot 8. As can be seen, in the paging table, there are four candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource on the paging table can be indicated using two bits.
[00201] [00201] Likewise, when the value of M is 2, the start position or the time domain position of each time domain resource in the paging frame can also be indicated using the half frame indication and the indication specific position together. A specific implementation is similar to the implementation in which the value of M is 4. Details are not described here again.
[00202] [00202] Optionally, in other modalities, locations of starting positions or time domain positions of the two time domain resources in the paging table can be specified in advance. For example, it is specified in advance that the start position or time domain position of one of the two time domain resources on the paging frame is located in slot 0 through slot 3. In this way, two bits can be used to indicate the location of the start position or the time domain position of either of the two time domain resources on the paging table. For another example, it is specified in advance that the start position or time domain position of one of the two time domain resources is located in the first half frame of the paging frame, that is, slot 0 to slot 4. In this way, three bits can be used to indicate the location of the start position or the time domain position of either of the two time domain resources in the paging frame. For another example, it is specified in advance that the starting position or the time domain position of one of the two time domain resources is located in the second half frame of the paging frame, that is, slot 5 to slot 9. In this way, three bits can be used to indicate the location of the start position or the time domain position of either of the two time domain resources in the paging frame. For another example, it is specified in advance that the start position or time domain position of the first of the two time domain resources is located in the first half frame of the paging frame, that is, slot 0 to slot 4 of this In this way, three bits can be used to indicate the location of the start position or the time domain position of the first time domain resource in the paging frame. In addition, it is specified in advance that the start position or time domain position of the second of the two time domain resources is located in the second half frame of the paging frame, that is, slot 5 to slot 9. In this way, three bits can be used to indicate the location of the start position or the time domain position of the second time domain resource in the paging frame.
[00203] [00203] The initial position of the pagination occasion is related to the indication of multiplexing by frequency division of the SSB. When there is only one PO, the starting position of the PO may not be configured. When there are two POs, a starting position of a PO can be configured.
[00204] [00204] The 15 kHz subcarrier spacing is still used as an example. The value of M is assumed to be 1.
[00205] [00205] Optionally, in some modalities, the starting position or the time domain position of the first time domain resource can be from slot 0 to slot 8. As can be seen, in the paging table, there is a maximum of nine candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource on the paging table can be indicated using four bits.
[00206] [00206] Optionally, in other modalities, the starting position or the time domain position of the first time domain resource can be from slot 0 to slot 7. As can be seen, in the paging table, there are eight candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource on the paging table can be indicated using two bits.
[00207] [00207] Optionally, in other modalities, the starting position or the time domain position of the first time domain resource can be slot 0 to slot 3. As can be seen, in the paging table, there are four candidate positions for each time domain resource. In this case, the location of the start position or the time domain position of each time domain resource on the paging table can be indicated using two bits.
[00208] [00208] The sub-carrier spacing of 30 kHz is used as an example. The value of M is assumed to be 1.
[00209] [00209] Optionally, in some modalities, the start position or the time domain position of the first time domain resource can be located in slot 0 to slot 18. The paging position information can directly indicate the position of the first resource time domain. In this case, the length of the paging position information is five bits.
[00210] [00210] Optionally, in some modalities, the paging position information can indicate the position of the first time domain resource using the half-frame indication and the specific position indication together. For a specific implementation, see the example where the subcarrier spacing is 15 kHz and the value of M is 4. Details are not described here again.
[00211] [00211] Optionally, in other modalities, the location of the starting position or the time domain position of the time domain resource in the paging table can be predefined. For example, it is specified in advance that the start position or the time domain position of the time domain resource in the paging frame is located in slot 0 to slot 7. Thus, three bits can be used to indicate the location of the start position or time domain position of the time domain resource in the paging frame. For another example, it is specified in advance that the start position or the time domain position of the time domain feature on the paging frame is located in slot 10 to slot 17. Thus, three bits can be used to indicate the location of the start position or the time domain position of the time domain resource in the paging table.
[00212] [00212] An implementation in which the subcarrier spacing is 30 kHz and the value of M is 2 is similar to the specific implementation in which the subcarrier spacing is 15 kHz and the value of M is 2. Details are not described here again . An implementation in which the subcarrier spacing is 30 kHz and the value of M is 4 is similar to the specific implementation in which the subcarrier spacing is 15 kHz and the value of M is 4. Details are not described here again.
[00213] [00213] An implementation in which the subcarrier spacing is 60 kHz or 120 kHz is similar to the implementation in which the subcarrier spacing is 15 kHz or 30 kHz. The details are not described here again.
[00214] [00214] Optionally, in some embodiments, the paging position information includes a paging position index, where the paging position index is used to indicate the time domain positions of the M time domain resources on the chart. pagination. More specifically, the paging position index is used to indicate the location of the initial position of each of the M time domain resources in the paging table.
[00215] [00215] In the positions of time domain resources shown in Table 1 to Table 20, the positions of time domain resources in each group can correspond to an index. A time domain resource group indicates all M time domain resources. A paging position index can be allocated to each group of time domain resources based on Table 1 to Table 21. Each paging position index corresponds to the positions of the M time domain resources in a paging table. For example, Table 21 is a result obtained by adding an index of pagination position based on Table 1. Table 21 Indian Index PO 0 PO 1 PO 2 PO 3 PO 0 PO 1 PO 2 PO 3 ce ce 0 0 2 4 6 8 0 3 6 8 1 0 2 4 7 9 0 4 6 8 2 0 2 4 8 10 1 3 5 7 3 0 2 5 7 11 1 3 5 8 4 0 2 5 8 12 1 3 6 8 5 0 2 6 8 13 1 4 6 8 6 0 3 5 7 14 2 4 6 8 7 0 3 5 8 15 1 3 6 8
[00216] [00216] As shown in Table 21, when the paging position index received by the terminal device is 4, the terminal device can determine that the initial positions of the four time domain resources are distributed in subframes 0, 2, 5 and 8 .
[00217] [00217] Paging position information includes at least one starting position and the duration of the target paging occasion in the paging table.
[00218] [00218] When a set of paging message control features is the same as an ISDN control feature set, a maximum number of paging occasions in one frame or two frames is 1. This is to satisfy a requirement beam scan. When a way of multiplexing the SSB and RMSI is frequency division multiplexing, a maximum number of paging occasions in the paging message in the DRX cycle can be determined based on an SSB period or an RMSI period.
[00219] [00219] When the paging message control information indicates that there is a separate search space, the initial position of the paging occasion can also be configured separately. The starting position of the paging occasion can be configured separately and a configuration parameter can be configured based on the subcarrier spacing.
[00220] [00220] Optionally, in other modalities, the pagination position index can directly indicate the time domain position of the target paging occasion in the pagination table. Still using Table 21 as an example, Table 21 shows that an index is defined for each time domain resource group. In other embodiments, an index can be defined for a position for each time domain resource. In this way, the terminal device can directly determine the time domain position or the starting position of the target paging occasion in the paging table based on the index.
[00221] [00221] Optionally, in some embodiments, the target paging feature includes position information from the paging table, and the position information from the paging table includes a frame number from the paging table. In that case, the terminal device determines a target paging resource includes: the terminal device determines the frame number of the paging frame based on a paging frame offset. A unit of the paging frame offset is a frame.
[00222] [00222] The paging frame offset is related to at least one of the following: the period of the sync signal block, the time domain position of the sync signal block actually sent by the network device and the domain position of the candidate block of synchronization signals. The time domain position of the block of sync signals actually sent by the network device can be one of a system frame number, a subframe, a slot or a symbol. Likewise, the time domain position of the candidate sync signal block can be one of the system frame number, a subframe, a slot or a symbol.
[00223] [00223] Optionally, in some modalities, the displacement of the paging table can be determined based on the SSB period. Specifically, the SSB period is assumed to be S. In this case, a frame in which the SSB is located is SFN mod S = K, where SFN indicates the frame number of the paging frame, K indicates an index of one frame in which the SSB is located in the SSB period, and mod indicates a module operation. When S is less than (T div N), the paging frame offset is K; or when S is greater than (T div N), the paging frame offset is S - K. Optionally, in some embodiments, if S is equal to (T div N), the paging frame offset may be K. Optionally, in other modalities, if S is equal to (T div N), the paging table offset can be S - K.
[00224] [00224] Optionally, in some modalities, the frame index in which the SSB is located in the period can be a real SSB index.
[00225] [00225] Optionally, in some modalities, the frame index in which the SSB is located in the period can also be a reordered index of the SSB.
[00226] [00226] The current index is an index of the SSB in the period. For example, an index of an SSB 0 is 0, an index of an SSB 1 is 1 and an index of an SSB 2 is 2. Even if SSB 0 and SSB 1 are not sent, the index of SSB2 is still 2 .
[00227] [00227] The reordered index is an index of the SSB actually sent by the network device. For example, the index of SSB 0 is 0, the index of SSB 1 is 1, the index of SSB 2 is 2 and the index of an SSB 3 is 3. Assuming that SSB 0 and SSB 2 are not sent, the SSB index 1 is changed to 0 and SSB index 3 is changed to 1.
[00228] [00228] Optionally, in other modalities, the offset of the paging frame can also be determined based on a period of the set of bursts of synchronization signal. In this case, S can indicate the period of the set of burst bursts.
[00229] [00229] Optionally, in other modalities, the paging table offset can also be predefined, or is indicated by the network device. For example, the network device may send referral information to the terminal device to indicate the shift of the paging frame. It can be understood that the paging frame offset can be a positive number, or it can be a negative number, or it can be 0. The network device can send the indication information to the terminal device in a plurality of ways that can be identified by the terminal device, to indicate the shift of the paging frame. For example, an absolute value of the displacement can be indicated, or a relative value of the displacement can be indicated. In an implementation, the network device can indicate a number of frames by which the paging frame is shifted, or it can indicate a number of frames by which the paging frame is shifted to the right (by how many frames the paging frame is moved by delayed) or a number of frames by which the paging frame is shifted to the left (by how many frames the paging frame is advanced).
[00230] [00230] Optionally, in other modalities, the paging frame offset can also be determined based on an index of a frame in which the set of sync signal bursts is located, in the period of the set of sync signal bursts . For example, the frame in which the burst burst is located is SFN mod S = K, where a value of K is an index of the burst burst.
[00231] [00231] Optionally, in some embodiments, the fact that the terminal device determines the frame number of the paging frame based on an offset of the paging frame includes: the terminal device can determine the frame number of the paging frame based on in the discontinuous reception cycle (Discontinous Reception, DRX), the number of pagination occasions in the DRX cycle, identification information of the terminal device, and the displacement of the paging table. It can be understood that the paging table offset is relative, and it can be a left shift or a right shift or it is not a shift. To be specific, the paging frame offset can be a positive number, a negative number, or 0.
[00232] [00232] Optionally, in some modalities, the terminal device determines the frame number of the paging frame based on the following formula: SFN mod T = (T div N) * (UE_ID mod N) + offset Formula 1.3 where SFN indicates the frame number of the paging frame, T indicates DRX, N = min (T, nB), nB indicates the number of paging occasions in the DRX cycle, div indicates a division operation, min indicates a definition operation of a minimum value, UE_ID indicates the identification information of the terminal device, mod indicates a module operation, and the offset indicates the paging frame offset.
[00233] [00233] Optionally, in some implementations, the offset of the paging frame can be understood as an offset of a pagination frame to be determined in relation to an SFNref reference paging frame. The offset between the reference paging frame SFNref and the pagination frame to be determined SFN can be an offset to the left of one or more frames, or an offset to the right of one or more frames, or it is not an offset. To be specific, an offset value can be a positive integer, or it can be a negative integer or it is 0. As can be seen, the frame numbers of the reference paging frame SFNref and the frame number to be -determined SFN satisfy: SFNref = SFN + Offset or SFNref = SFN - Offset or SFNref = SFN.
[00234] [00234] For example, the terminal device determines the frame number of the paging frame based on the following formula: (SFN - offset) mod T = (T div N) * (UE_ID mod N) Formula 1.4
[00235] [00235] For another example, the terminal device determines the SFN frame number of the paging frame, where the SFN frame number of the paging frame satisfies: (SFN + offset) mod T = (T div N) * (UE_ID mod N).
[00236] [00236] For another example, if the paging frame offset is 0, the terminal device determines the SFN frame number of the paging frame, where the SFN frame number of the paging frame satisfies: SFN mod T = (T div N) * (UE_ID mod N), where the offset indicates the offset of the paging frame, SFN indicates the frame number of the paging frame, T indicates the DRX cycle, N = min (T, nB), nB indicates the number of pagination occasions in the DRX cycle, div indicates a division operation, min indicates an operation to set a minimum value, UE_ID indicates the identification information of the terminal device, mod indicates a module operation and N indicates a quantity paging frames in the XRD cycle.
[00237] [00237] It should be understood that Formula 1.4 is intended to determine the frame number of the paging frame based on the frame number (SFN) of an initial paging frame and the offset of the paging frame. Therefore, the frame number of the paging frame can be determined based on the frame number of the initial paging frame and the offset of the paging frame. It can be understood that, alternatively, the frame number of the paging frame can be determined based on the frame number of the initial paging frame minus the paging frame offset. The addition or subtraction of the paging frame offset depends on whether the paging frame offset is positive or negative. It can be understood that the SFNref frame number of the reference paging frame satisfies: SFNref mod T = (T div N) * (UE_ID mod N). The Offset paging frame offset can be a relative value or an absolute value sent by the network device. For example, if the network device sends a relative offset value, where the offset is a negative number (for example, –1), (SFN - offset) in Formula 1.4 is actually SFN + 1, or SNF plus a value absolute of the paging table offset. Therefore, a variant of Formula 1.4 can be (SFN + offset) mod T = (T div N) * (UE_ID mod N). In that case, the network device can send the absolute offset value. Regardless of addition or subtraction, the frame number of the paging frame can be considered to be determined based on the frame number of the reference paging frame, where the frame number of the reference paging frame is determined based on the number frame of the initial paging frame plus or minus the paging frame shift.
[00238] [00238] Optionally, in other modalities, the terminal device can further calculate an SFN 1 frame number from the initial paging frame using a method to calculate a frame number from a paging frame in an LTE system and then add the paging frame shift to SFN 1 to obtain the frame number of the paging frame.
[00239] [00239] Optionally, when the offset value is configured by the base station, the offset value can be a positive integer, or it can be a negative integer, or it can be 0.
[00240] [00240] The displacement value can be determined based on the period and / or the position of the SSB, or it can be determined based on the period of an SMTC. For example, if the SSB period is T, the offset value can be from 0 to T - 1, or –T + 1 to 0, or –T / 2 + 1 to T / 2 - 1, or –T / 2 to T / 2, or –T / 2–1 to T / 2 + 1. For example, if the SSB period is 5 ms or 10 ms, the offset offset can be 0. For example, if the SSB period is is 20 ms, the offset can be one or more of 0 and 1, or one or more of –1 and 0, or it can be any one or more of –1, 0 and 1. For example, if the SSB period is 40 ms, the offset can be one or more of 0, 1, 2 and 3, or any one or more of –3, –2, –1 and 0, or it can be any one or more of –2, - 1 , 0, 1 and 2, or can be any one or more of –1, 0 and 1. For example, if the SSB period is 80 ms, the offset can be any one or more of 0, 1, 2, 3 , 4, 5, 6 and 7 or any one or more of –7, –6, –5, –4, –3, –2, –1 and 0, or can be one or more of –4, –3, –2, –1, 0, 1, 2, 3 and 4, or it can be one or more of –3, –2, –1, 0, 1, 2 and 3. For example, if the SSB period is 80 ms, the displacement o can be any one or more of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15, or any one or more of –15, - 14 –13, - 12, –11, –10, –9, –8, –7, –6, –5, –4, –3, –2, –1 and 0, or can be any one or more of –7, –6, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5, 6 and 7, or can be any one or more of
[00241] [00241] The offset value can be determined based on the period and / or a position of the SMTC (RRM measurement timing configuration based on SS block). For example, if the SMTC period is T, the offset value can be from 0 to T - 1, or –T + 1 to 0, or –T / 2 + 1 to T / 2 - 1, or –T / 2 to T / 2, or –T / 2 - 1 to T / 2 + 1. For example, if the SMTC period is 5 ms or 10 ms, the offset offset can be 0. For example, if the SMTC period is 20 ms, the offset can be one or more of 0 and 1, or one or more of –1 and 0, or it can be any one or more of –1, 0 and 1. For example, if the SMTC period is 40 ms, the offset can be any one or more of 0, 1, 2 and 3, or any one or more of –3, –2, –1 and 0, or it can be any one or more of –2, - 1, 0, 1 and 2, or it can be any one or more of –1, 0 and 1. For example, if the SMTC period is 80 ms, the offset can be any one or more of 0, 1, 2, 3, 4, 5, 6 and 7, or any one or more of –7, –6, –5, –4, - 3, –2, –1 and 0, or can be any one or more of –4, –3, - 2, –1, 0, 1, 2, 3 and 4, or it can be any one or more of - 3, –2, –1, 0, 1, 2, and 3. For example, if the period the SMTC is 80 ms, the offset can be any one or more than 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15, or any or more than –15, –14, –13, –12, –11, –10, –9, - 8, –7, –6, –5, –4, –3, –2, –1 and 0, or it can be any one or more of –7, –6, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5, 6 and 7, or it can be any one or more than –8, –7, –6, –5, –4, –3, –2, –1, 0, 1, 2, 3, 4, 5, 6, 7 and 8. For example, when
[00242] [00242] The network device can configure values of N displacements, where a value of each displacement can correspond to a PO, or each displacement corresponds to a paging table. The N values can be any or all of the values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 , 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 and 32. A value of N can be configured based on an amount of POs or an amount of PFs in the SSB period or the SMTC period. For example, if the SSB period includes only a PO or PF, the offset value can be 1 or not be configured. For example, if the SSB or SMTC period includes only two POs or PFs, the offset value can be 1 or 2 or not be configured. For example, if the SSB or SMTC period includes only three POs or PFs, the offset value can be 1 or 2 or 3 or not be configured. For example, if the SSB or SMTC period includes only four POs or PFs, the offset value can be 1 or 2 or 3 or 4 or not be configured. For example, if the SSB or SMTC period includes only five POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or not be configured. For example, if the SSB or SMTC period includes only six POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or not be configured. For example, if the SSB or SMTC period includes only seven POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or not be configured. For example, if the SSB or SMTC period includes only eight POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or not be configured. For example, if the SSB or SMTC period includes only nine POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or not be configured. For example, if the SSB or SMTC period includes only 10 POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 or not be configured. For example, if the SSB or SMTC period includes only 11 POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 or 11 or not be configured. For example, if the SSB or SMTC period includes only 15 POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 7 or 8 or 9 or 10 or 11 or 12 or 13 or 14 or 15 or not to be configured. For example, if the SSB or SMTC period includes only 16 POs or PFs, the offset value can be 1 or 2 or 3 or 4 or 5 or 6 or 7 or 7 or 8 or 9 or 10 or 11 or 12 or 13 or 14 or 15 or 16 or not to be configured. The configured quantity can be equal to the quantity of POs or PFs in the period of the SSB or SMTC.
[00243] [00243] Alternatively, the displacement value can be configured based on the maximum values of the SSB and SMTC periods. For example, in a configuration method, the values that can be configured for the offset are {0, 1, 2, 3, ..., max (T1, T2) - 1}, where T1 indicates the period of the SSB and T2 indicates the SMTC period. T1 and T2 units can be frames. For example, when the SSB period is 20 ms and the SMTC period is 40 ms, the values that can be configured are {0, 1, 2, 3}.
[00244] [00244] Figure 3 is a schematic diagram of a paging table shift according to one embodiment of this request. As shown in Figure 3, when there is no offset from the paging frame, the frame numbers of the frames in which a paging frame 1, a paging frame 2 and a paging frame 3 are located are 0, 4 and 10, respectively . The frame numbers in which an SS 1 frame and an SS 2 frame are located are 3 and 7, respectively. According to the method above, a paging frame offset can be determined to be 3. In this case, the frame numbers of the frames in which paging frame 1, paging frame 2 and paging frame 3 are located are updated to 3, 7 and 13, respectively. In this case, paging frame 1 is multiplexing by time division with the SS frame 1 and paging frame 2 is in multiplexing by time division with SS frame 2.
[00245] [00245] Figure 4 is a schematic diagram of another paging table offset according to one modality of this request. As shown in Figure 4, when there is no offset from the paging frame, the frame numbers of the frames in which a paging frame 1, a paging frame 2, a paging frame 3, a paging frame 4 and a pagination 5 are located are 0, 2, 4, 6 and 8, respectively. The frame numbers in which the SS frames are located are 3 and 7, respectively. According to the above method, it can be determined that a paging table offset is
[00246] [00246] Figure 5 is a schematic diagram of another paging table offset according to a modality of this request. As shown in Figure 5, when there is no paging frame offset, the frame numbers in which a paging frame 1, a paging frame 2 and a paging frame 3 are located are 0, 4 and 8, respectively. The frame numbers in which the SS frames are located are 1, 3, 5, 7, 9 and 11, respectively. According to the above method, it can be determined that a paging table offset is
[00247] [00247] As a paging frame and an SS frame are multiplexed, a paging message can be multiplexed by time division with an SSB. This can save time domain resources so that resources saved in the time domain can be used to send other messages.
[00248] [00248] When frequency division multiplexing is performed on a plurality of POs (or DCI of a plurality of POs), the plurality of POs can be POs where frequency division multiplexing is performed on a plurality of frames of frequency. pagination.
[00249] [00249] Finally, an operation of module 1024 or module 2048 can be performed on a value of an SFN system frame number of a paging message that is calculated based on a UE ID, and on a system frame number obtained by performing the module operation is a frame number of a frame in which the UE ID paging message is located. For example, a module operation method is ((SFN +/– offset) mod T) mod 1024 = (T div N) * (UE_ID mod N). For example, a module operation method is SFN 2 mod 1024 = SFN 3, where SFN 2 = SFN 1 + offset, SFN 2 is SFN 1 + offset, and SFN 1 is a frame number in a paging frame calculated using a method to calculate a frame number from a paging frame in an LTE system.
[00250] [00250] Optionally, in some modalities, the target paging feature includes the position information of the monitoring window, where the position information of the monitoring window includes an initial position of the target monitoring window corresponding to the terminal device in the Q windows. monitoring, where a pagination occasion includes the Q monitoring windows; and that the terminal device determines a target paging feature includes: the terminal device determines the starting position of the target monitoring window based on a monitoring window offset.
[00251] [00251] Optionally, in some modalities, Q is a positive integer greater than or equal to 2.
[00252] [00252] Optionally, in other modalities, Q is a positive integer less than or equal to 2.
[00253] [00253] Optionally, in some modalities, the duration of each of the Q monitoring windows is the same.
[00254] [00254] Optionally, in some modalities, the monitoring window offset can be determined based on a monitoring window index. At least two monitoring windows whose indexes are different correspond to different monitoring window offsets.
[00255] [00255] A paging frame includes 10 slots, where a slot 0 to a slot 4 are slots used for downlink transmission, and a slot 5 to a slot 9 are slots used for uplink transmission. The monitoring window starts at slot 2, and a value of Q is 4. The duration of each monitoring window is one slot. In this way, the first three monitoring windows can be located in slot 2 to slot 4, respectively, and the last monitoring window needs to be moved in five slots for the next paging frame. In other words, the monitoring window offsets of the first three monitoring windows are 0, and the monitoring window offsets of the last monitoring window is 5.
[00256] [00256] Optionally, in some modalities, time domain resources in a monitoring window are consecutive.
[00257] [00257] Optionally, in some modalities, a number of time domain resources in a monitoring window can be configured and can have some or all of the values of 0.5 slot, one slot, two slots and four slots. The paging message is related to SSB frequency division multiplexing. For example, in frequency division multiplexing, the amount can be 0.5 slot.
[00258] [00258] When the paging message monitoring windows overlap, the control information for a plurality of paging messages sent in a paging message detection window can correspond to different SSBs.
[00259] [00259] The paging message monitoring windows may overlap. To be specific, a monitoring window is associated with kmonitor SSBs, where a kmonitor coefficient can be configured, and a value can be any value of 1, 2, 3, 4, 5, 6, 7 and 8.
[00260] [00260] When a plurality of paging messages are sent in a slot, it can be specified in advance that the paging message control information in a paging message detection window can be sent in a sequence of time, or in a frequency sequence.
[00261] [00261] For example, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent in the first symbol in the slot, and the control information of the second paging message is sent in the second symbol in the slot.
[00262] [00262] Alternatively, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent in the second symbol in the slot, and the control information of the second paging message is sent in the third symbol in the slot.
[00263] [00263] Alternatively, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent on the first symbol in the slot and the control information of the second paging message is sent on the third symbol in the slot.
[00264] [00264] Alternatively, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent in the first symbol of the slot, the control information of the second paging message is sent in the second symbol in the slot and the control information for the third part of the paging message is sent in the third symbol in the slot.
[00265] [00265] Alternatively, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent on the first or second symbol in the slot and the control information of the second paging message is sent the third symbol in the slot.
[00266] [00266] Alternatively, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent in the first symbol in the slot, and the control information of the second paging message is sent in the second or third symbol in the slot.
[00267] [00267] Alternatively, it can be prescribed in a protocol or indicated by the network device that, the control information of the first paging message is sent in the first symbol in the slot, and the control information of the second paging message is sent in the seventh symbol in the slot.
[00268] [00268] The network device sends paging messages using different beams in different monitoring windows. In the target monitoring window, a paging message is sent using a beam in which the terminal device is located.
[00269] [00269] Optionally, in some embodiments, the terminal device determines the starting position of the target monitoring window based on a displacement of the monitoring window includes: the terminal device determines the starting position of the target monitoring window based on the following Formula: Md = I + window offset + x * floor (SSB / w) Formula 1.5 where Md indicates the starting position of the target monitoring window, I indicates a start time of a time domain resource in which the pagination occasion is located , the window offset indicates the monitoring window offset, x indicates the duration of each of the Q monitoring windows or a time interval between the start time of each monitoring window and the start time of the next monitoring window , the SSB indicates at least one of the following types of information: a time index of a block of target sync signals with an association relationship with the monitoring window a lvo, a time index of a candidate sync signal block having an association relationship with the target watch window, and a target watch window index, w indicates a number of sync signal blocks associated with the watch window target, and the floor indicates a round-down operation. The monitoring window offset can be a time offset of the first of the monitoring windows relative to a reference position. Alternatively, the monitoring window offset can be a sum of a fixed time offset and a time offset of the first of the monitoring windows in relation to a reference position. The fixed time offset can be determined based on the information configured by the network device. Since fixed time offset is used, the monitoring windows can be relatively centralized to facilitate detection by the terminal device.
[00270] [00270] Optionally, in some modalities, the displacement of the monitoring window is related to an SSB displacement.
[00271] [00271] Optionally, in some modalities, the target monitoring window is associated with one or more blocks of synchronization signals.
[00272] [00272] The association relationship can be any one of relationships, such as a quasi-co-location relationship (Quasi-Co-Location, QCL), a relationship of having the same beam, and a relationship of having the same antenna port .
[00273] [00273] Optionally, in some modalities, if a value of w is 1, the variants of Formula 1.5 can be the following Formulas: Md = I + window offset + x * SSB Formula 1.6 Md = I + window offset + floor (x * SSB) Formula 1.7 Md = Iwindow offset + floor (x * SSB) Formula 1.7
[00274] [00274] The Iwindow offset indicates an initial position of a PO. Iwindow offset can include two parts: for example, Iwindow offset = Iwindow offset 1 + Iwindow offset 2, where the first part of Iwindow offset 1 can be a time domain position or a position in a PDCCH slot of a message. pagination corresponding to an SS / PBCH block index 0 or Iwindow offset 1 is a PDCCH time domain initial position of a paging message corresponding to an SS / PBCH block index i - 1. The second part of Iwindow offset 2 can include time domain position shifts or pagination message PDCCH slot positions corresponding to different SSB indexes relative to SSB positions, or is an amount of uplink slots between the initial position of PDCCH time domain of paging message corresponding to SS / PBCH i - 1 block index and a PDCCH time domain of paging message corresponding to SS / PBCH i block index , or is a number of slots that cannot be used to transmit a paging message. The offset may be caused by an SSB index or it may be caused by an uplink / downlink collision. For example, one way to determine Iwindow offset 2 is KDU, P * NUP, T, where KDU, P is a number of slots between the starting position of a PO and a slot or time domain feature of the corresponding paging message. to the SS / PBCH block index i, NUP, T is an amount of uplink slots at a downlink-to-uplink switching point periodicity, a method for calculating KDU, P is the floor (floor ( x * i) / NP, slot, T), NUP, T is an amount of uplink slots in the downlink-to-uplink switching point periodicity or an amount of slots that cannot be used to transmit a paging message, and NP, slot, T is a number of downlink and / or flexible slots in the downlink-to-uplink switching point periodicity or a number of slots that can be used to transmit a message pagination.
[00275] [00275] In Formula 1.6, the meaning of each term is the same as in Formula 1.5. The details are not described here again.
[00276] [00276] Optionally, in some modalities, before the terminal device determines the starting position of the target monitoring window based on the displacement of the monitoring window, the method also includes: the terminal device determines that the target monitoring window is located in ⌈ Qd / Qmax⌉ -th pagination frame, where Qmax indicates a maximum number of monitoring windows   included in a paging frame, and   indicates an up rounding operation.
[00277] [00277] Optionally, in some modalities, Qmax is determined based on at least one duration of each of the Q monitoring windows, a number of blocks of synchronization signals, a number of paging messages and a spacing of subcarriers.
[00278] [00278] Optionally, in other modalities, Qmax is a predefined value.
[00279] [00279] Optionally, in other modalities, Qmax is determined based on an indication of the network device.
[00280] [00280] Optionally, in some modalities, the time domain resources occupied by the Q monitoring windows are consecutive time domain resources or non-consecutive time domain resources. Non-consecutive time domain resources belong to a segment of consecutive time domain resources and, in the consecutive time domain resource segment, time domain resources other than the time domain resources occupied by the Q windows. monitoring have been determined to transmit information other than the paging message.
[00281] [00281] Optionally, in some modalities, a time domain position of each monitoring window can be the same as a position in an SSB slot having an association relationship with the monitoring window. The duration of each monitoring window is the same. A unit of the duration of each monitoring window can be a slot.
[00282] [00282] Optionally, in some modalities, the paging message identification information on at least two of the N paging occasions are different, where the identification information can be temporary paging radio network identifiers (Paging-Radio Network Temporary Identifier, P-RNTI) or random access preambles.
[00283] [00283] Optionally, in some embodiments, when there is a plurality of P-RNTIs, the plurality of P-RNTIs can be used to distinguish between paging messages from different POs, or used to distinguish between paging messages from different groups of devices terminals. An amount of the plurality of P-RNTIs can be any numerical value of 2, 4, 8, 16, 32 and 64. The terminal device or the network device can select an amount of P-RNTIs based on at least one of a period of a random access channel occasion, duration of a frame, and period of a set of bursts of synchronization signal within the duration of the XRD cycle. The number of the plurality of P-RNTIs can also be configured by the network device.
[00284] [00284] When P-RNTIs are used to distinguish between different POs, P-RNTIs can be related to PO indexes. To be specific, a P-RNTI for a PO whose index is i is P-RNTI0 + i, where P-RNTI0 indicates an initial P-RNTI, and i indicates the PO index. For example, if a P-RNTI from PO 0 is P-RNTI0, a P-RNTI from PO 1 is P-RNTI0 + 1, a P-RNTI from PO 2 is P-RNTI0 + 2 and a P-RNTI from PO 3 is P- RNTI0 + 3. The first PO (that is, the PO whose index is 0) can be a PO in a system frame, or it can be the first PO in frequency division multiplexing. When the terminal device detects DCI from different POs,
[00285] [00285] When a plurality of random access preambles is used to distinguish between different POs, the index values and a number of random access preambles used for a paging message can be related to the PO indexes. For example, a PO random access preamble whose index is i is i * N a (i + 1) * N - 1. For example, a PO 0 random access preamble is 0 to N - 1, a random access preamble of PO 1 is N to 2N - 1, a preamble of random access of PO 2 is 2N to 3N - 1 and a random access preamble of PO 3 is 3N to 4N - 1. Alternatively, random access preambles of different POs are non-consecutive, and can be i + K (0 to N - 1), where K indicates a number of POs. For example, a PO 0 random access preamble is 0, K, 2K, ..., K (N - 1); a PO 1 random access preamble is 1, K + 1, 2K + 1, ..., K (N - 1) + 1; a PO 2 random access preamble is 2, K + 2, 2K + 2, ..., K (N - 1) +2; and a PO 3 random access preamble is 3, K + 3, 2K + 3, ..., K (N - 1) +3. Upon detecting the random access preambles from different POs, the network device can distinguish between the information received at the different POs.
[00286] [00286] Optionally, in some modalities, before the terminal device receives the target paging message on the target paging resource, the method also includes: the terminal device receives a paging indication sent by the network device, where the paging indication is used to indicate that the network device will send the target paging message.
[00287] [00287] The network device can send a system update indication, an ETWS indication, and a CMAS indication along with the paging indication. The system update indication can include a bit, used to indicate whether the system information is changed. When the terminal device receives the system update indication, the terminal device determines, based on the contents of the system update indication, whether the system information needs to be updated. The system update indication can also be a plurality of bits, and the system update indication of the plurality of bits is used to indicate what type of system information is updated. For example, 00100 indicates that a system information block 3 is updated.
[00288] [00288] Optionally, in some modalities, the method also includes: the terminal device receives time domain unit indication information sent by the network device, where the time domain unit indication information is used to indicate a quantity of time domain units included in the paging table.
[00289] [00289] Optionally, in some modalities, the information indicating the time domain unit may include the subcarrier spacing. In this way, the terminal device can determine, based on the subcarrier spacing, the number of time domain units included in the paging table.
[00290] [00290] For example, subcarrier spacing can be configured on a PBCH, and can be configured using an SSB index and a half-frame indication. For example, in a low frequency case (less than 6 GHz), a bit in the SSB index can be used to indicate whether the subcarrier spacing is 15 kHz or 30 kHz; or, in the case of a high frequency (greater than 6 GHz), the half-frame indication can be used to indicate whether the subcarrier spacing is 60 kHz or 120 kHz.
[00291] [00291] Optionally, in other modalities, the time domain unit indication information can be the number of time domain units included in the paging table.
[00292] [00292] Figure 6 is a schematic flowchart of another method for transmitting a paging message according to one embodiment of this request.
[00293] [00293] 601. A network device determines a paging facility, where the paging facility includes at least one of the following types of information: position information for N paging occasions, position information for a paging table, and information position of a monitoring window.
[00294] [00294] 602. The network device sends a paging message on the paging facility to a terminal device.
[00295] [00295] Optionally, in some modalities, the pagination feature includes the position information of the N pagination occasions, and the N pagination occasions are located in M time domain resources, where N is a positive integer greater than or equal a 1, M is a positive integer greater than or equal to 1 and less than or equal to N, and a position of each of the M time domain resources in the paging frame is related to at least one subcarrier spacing, one position time domain of a block of sync signals actually sent by the network device, and a time domain position of a candidate sync signal block.
[00296] [00296] Optionally, in some embodiments, the network device determines a paging resource includes: the network device determines the position of each of the M time domain resources on the paging table based on a value of M.
[00297] [00297] Optionally, in other modalities, a time domain position or the initial position of each of the M time domain resources in the paging table includes: when M is equal to 1, time domain positions or starting positions of the M time domain resources in the paging frame are at least one of the following time domain units: time domain unit 0 in the paging frame, time domain unit K1 / 2 in the paging frame, a unit of time time domain to send a block of sync signals on the paging frame by the network device, and a time domain unit next to a time domain unit to send a last block of sync signals on the paging frame by the device network, where K1 is a positive integer and can be divided exactly by 2; when M is equal to 2, a time domain position or the initial position of the first of the M time domain resources in the paging frame is the time domain unit 0 in the paging frame, and a time domain position or the starting position of the second of the M time domain resources in the paging frame is the K2 / 2 time domain unit in the paging frame, where K2 is a positive integer greater than 2 and can be exactly divided by 2; when M is equal to 4, a time domain position or the initial position of the first of the M time domain resources in the paging frame is the time domain unit 0 in the paging frame, a time domain position or the start position of the second M time domain resources on the paging table is the K2 / 4 time domain unit on the paging table, a time domain position or the start position of a third of the M time domain resources in the paging table is the time domain unit K2 / 2 in the paging table, and a time domain position or the initial position of the fourth M time domain resources is the 3xK2 / 4 time domain unit in paging table; or when M equals 4 and the paging table includes 10 time domain units, a time domain position or the initial position of the first of the M time domain resources on the paging table is the time domain unit 0 in the paging frame, a time domain position or the initial position of the second of the M time domain resources in the paging frame is time domain unit 3 in the paging frame, a time domain position or the starting position of the third of the M time domain resources in the paging table is the time domain unit 5 in the paging table, and a time domain position or the starting position of the fourth of the M time domain resources is the time domain unit 8 in the paging table.
[00298] [00298] A specific implementation in which the network device determines the position of each of the M time domain resources in the paging frame based on a value of M is similar to the specific implementation in which the terminal device determines the position of each of the M time domain resources on the paging table based on a value of M. One difference is that the terminal device only needs to determine the time domain position or the start position of the time domain resource in which the target paging occasion is located in the M time domain resources on the paging table, but the network device needs to determine the time domain position or the starting position of each of the M time domain resources on the paging table . For the specific implementation in which the network device determines the time domain position and the initial position of each time domain resource in the paging table, refer to the modality shown in Figure 2. The details are not described here again.
[00299] [00299] Optionally, in some modalities, the network device sends paging position information to the terminal device, where paging position information is used to indicate the time domain positions of the time domain resources in the frame. pagination.
[00300] [00300] For specific content of the paging position information sent by the network device, refer to the modality shown in Figure
[00301] [00301] Optionally, in some modalities, the target paging feature includes the position information of the paging table, and the position information of the paging table includes a frame number of the paging table; and that the network device determines that a target paging resource includes: the network device determines the frame number of the paging frame based on a paging frame offset. A specific implementation in which the network device determines the frame number of the paging frame based on the offset of the paging frame is the same as the specific implementation in which the terminal device determines the frame number of the paging frame based on the offset of the paging frame. paging table. The details are not described here again.
[00302] [00302] Optionally, in some embodiments, the paging frame shift is related to at least one of the following: a period of a block of sync signals, the time domain position of the block of sync signals actually sent by the device network, and the time domain position of the candidate sync signal block.
[00303] [00303] Likewise, the paging frame offset is determined based on the period of the synchronization signal block.
[00304] [00304] Likewise, the network device can determine the frame number of the paging frame based on a DRX discontinuous reception cycle, a number of paging occasions included in the DRX cycle, identification information of the terminal device, and the shift of the paging frame.
[00305] [00305] Optionally, in some modalities, the paging feature includes the position information of the monitoring window, and the position information of the monitoring window includes an initial position of each of the Q monitoring windows, where a pagination occasion includes the Q monitoring windows, and Q is a positive integer greater than or equal to 1; and the fact that the network device determines that a target paging feature includes: the network device determines the starting position of each of the Q monitoring windows based on a monitoring window offset.
[00306] [00306] A specific implementation in which the network device determines the initial position of the monitoring window based on the displacement of the monitoring window is similar to the specific implementation in which the terminal device determines the initial position of the target monitoring window based on the monitoring window offset. A difference lies in the fact that the terminal device only needs to determine the starting position of the target monitoring window, but the network device needs to determine the starting position of each monitoring window. The details are not described here again.
[00307] [00307] Likewise, before the network device determines the initial position of the monitoring window based on the displacement of the monitoring window, the method also includes: the network device determines that the q-th monitoring window of the Q windows The monitoring area is located in the ⌈q / Qmax⌉-th paging table, where Qmax indicates a maximum number of monitoring windows   included in a paging table,   indicates an up rounding operation, eq = 1 ,. .., Q.
[00308] [00308] Likewise, Qmax is determined based on at least one duration of each of the Q monitoring windows, a number of blocks of synchronization signals, a number of paging messages and the subcarrier spacing; or Qmax is a predefined value.
[00309] [00309] Optionally, in some modalities, the network device can also indicate the Qmax for the terminal device, so that the terminal device determines the position of the target monitoring window based on the Qmax.
[00310] [00310] Likewise, the time domain resources occupied by the Q monitoring windows are consecutive time domain resources or non-consecutive time domain resources. Non-consecutive time domain resources belong to a segment of consecutive time domain resources and, in the consecutive time domain resource segment, time domain resources other than the time domain resources occupied by the Q windows. monitoring were determined to transmit information other than a paging message.
[00311] [00311] The network device can use different beams in different monitoring windows in the Q monitoring windows to send paging messages to terminal devices in the beams. For example, assuming that Q equals 3, the network device can use a beam 1 in the first monitoring window to send a paging message to a terminal device in a beam 1 range; the network device may use a beam 2 in the second monitoring window to send a paging message to a terminal device in a beam 2 range; and the network device can use a beam 3 in the third monitoring window to send a paging message to a terminal device in a beam range
[00312] [00312] Figure 7 is a structural block diagram of a terminal device according to an embodiment of this application. As shown in Figure 7, terminal device 700 includes a processing unit 701 and a receiving unit 702.
[00313] [00313] Processing unit 701 is configured to determine a target paging resource, where the target paging resource includes at least one of the following types of information: position information for a target paging occasion, position information for a frame target paging and position information from a target monitoring window.
[00314] [00314] Receiving unit 702 is configured to receive a target paging message on the target paging facility, where the target paging message is a paging message sent by a network device to terminal device 700.
