RADIO RESOURCE MEASUREMENT METHOD, RADIO RESOURCE SELECTION METHOD, AND APPLIANCE
TECHNICAL FIELD [001] The modalities of this request relate to the field of communications technologies and, in particular, to a method of measuring radio resources, a method of selecting radio resources, and an apparatus.
BACKGROUND [002] As mobile communications technologies are evolving towards high speed, a large volume of data services, and the like, there are increasing demands for spectra during communication and transmission. A high bandwidth spectrum has a large amount of available bandwidth and therefore becomes an important resource that satisfies the requirements for high capacity and high bandwidth in future communications, and will also become an even more evolved target spectrum in a communications technology system 5G, the Partnership Project 3 Generation (3GPP), and Long Term Evolution Advanced (LTE-a). The high band spectrum includes a centimeter wave band and a millimeter wave band. The centimeter wave band is generally a spectrum within a range of 3 GHz to 30 GHz, and the millimeter wave band is generally a spectrum within a range of 30 GHz to 300 GHz.
[003] Cellular communication to which a high bandwidth wave is applied is referred to as high frequency cellular communication, and an area covered by a beam signal in high frequency cellular communication is referred to as a high frequency cell. Generally, a high

2/98 frequency has relatively small coverage, a beam signal is easily blocked, and a transfer rate (handover) and a transfer failure rate (handover) from a terminal (user equipment, UE) in a cellular environment high frequency are much higher than in a low frequency cell. In addition, a relatively high handover failure rate causes an interruption in user communication and a delay, resulting in a serious deterioration in the quality of service (Service Quality, QoS) of a service and user experience. Therefore, in high frequency cellular communication, it is a challenge to manage mobility in the UE.
[004] In a related technology, in a mobility management execution process in the UE, an important way to help a base station execute handover decision is to perform measurement of radio resource management (Radio Resource Management, RRM ) by the UE and report a measurement result to the base station. For example, RRM measurement in an existing LTE technology is based on an omnidirectionally sent cell-specific reference signal (CRS) or channel state information reference signal (CSIRS). The UE measures a reference signal in a serving cell, a neighboring intra-frequency cell or a neighboring inter-frequency cell, performs smooth Layer 3 filtering and averages a measurement result within a particular time, and reports the measurement result to the base station, so the base station determines whether to perform a transfer and selects a destination cell. However,

3/98 during high frequency cellular communication, to compensate for a loss of trajectory of a high bandwidth wave, communication coverage quality of high frequency cellular communication needs to be improved using a technology such as beam formation. In practice, when a reference signal used for RRM measurement is sent in the form of a beam, the reference signal cannot be measured in an RRM measurement manner in the prior art. In addition, as a high frequency signal has relatively low penetrability, fast attenuation of signal quality when encountering an obstruction, and the like, since the high frequency signal for communication between the UE and the base station deteriorates, it is very likely to affect normal communication between the UE and the base station.

An assisted access technology (LTE-assisted access, LAA) is studying and using an unlicensed spectrum from a 5 GHz band. In the pattern of the Institute of Engineers Electrical and Electronic 802.11ad (IEEE), a 60 GHz band is used for a wireless local area network (WLAN), and is generally used for short-range indoor communication in a range of approximately 10 meters. However, at the moment, a 6 GHz band or a higher band is not yet used in cellular communication technology. A major challenge of applying high bandwidth waves, such as a centimeter wave and a millimeter wave for cellular communication, lies in the fact that there is a relatively large free space attenuation in the bands; and affected by factors such as absorption and dispersion by air, rain, fog, a building, or other object, high bandwidth waves severely attenuate during propagation.

25/98 [0091] A beamforming technology is considered to be a potential technology that can be used to solve a problem of significant loss of a high bandwidth wave, such as a millimeter wave, and a multi-input antenna system and Massive multiple outlets (massive MIMO or large scale MIMO) is considered as a potential direction to implement beam forming technology in a high band. Figure 1 is a schematic diagram of beam formation. A base station transmits beams in different directions at different times, to implement full coverage for a sector that is also referred to as a cell. In the prior art, there are mainly three ways of bundling. A first way is a beam switching way, and it is usually implemented using an analog or radio frequency (RF) circuit. A second way is adaptive beam formation, and it is usually implemented using a digital circuit. A third way is the hybrid beam formation, and it is a combination of the two previous ways.
[0092] In high frequency communication, a beamforming technology needs to be used to improve coverage. Therefore, a reference signal used for measuring RRM can be sent in the form of a beam. However, RRM measurement on an existing LTE technology is based on an omnidirectional CRS or CSI-RS. Therefore, in high frequency cellular communication, a reference signal sent in a beam form cannot be measured effectively using the prior art.
[0093] To solve the previous technical problem, when a base station sends a beam reference signal in

26/98 a beam form for a terminal using a massive multiple input and multiple output antenna, the modalities of this application provide a method of measuring radio resources and an apparatus to measure the beam reference signal sent by the base station to the terminal, and send a measurement result obtained in the form of a measurement report to the base station, so that the base station can switch, based on the measurement report sent by the terminal, a cell or a downlink beam for communication with the terminal. In other words, the base station selects an appropriate cell and / or an appropriate downlink beam for the terminal for communication. It should be noted that, in the modalities provided in that order, the base station sends a beam reference signal in a beam form to the terminal. The beam reference signal includes, but is not limited to, a high frequency signal and a low frequency signal. In the modalities, a high frequency is used as an example for description, but the modalities of this request are not limited to that.
[0094] Using an evolved NodeB (eNB) and a terminal as an example, Figure 2 is a schematic diagram of an application scenario according to one modality of that order. Figure 2 includes a base station 100 and a terminal 200. An eNB is used as an example of base station 100. As shown in Figure 2, terminal 200 can separately establish a wireless communication connection with cells within the cover of the station base 100. Base station 100 can be a base station on an LTE or future communications system, such as a 5G base station, and include a
Petition 870190072993, of 07/30/2019, p. 11/32
27/98 plurality of base station forms that provide a low frequency cell, a high frequency cell, an unlicensed spectral cell and the like. In this modality, a high frequency cell is used as an example for description. Correspondingly, the terminal can be an evolved LTE terminal or a next generation terminal, such as a 5G terminal. In addition, this modality of this request is applicable to a scenario of coordination of high and low frequency cells and a scenario of an independent high frequency cell. A high frequency cell can include one or more transmit reception points (TRP) or an area covered by a high frequency signal provided by base station 100. In an embodiment provided in that order, with reference to Figure 2, the base station 100 sends measurement configuration information from one or more high frequency carriers to terminal 200, so that terminal 200 performs measurements such as RRM measurement based on measurement configuration information.
[0095] The measurement configuration information includes one or a combination of several of the following: a measurement frequency, a measurement bandwidth, an intra-frequency measurement configuration, an inter-frequency measurement configuration, a physical cell identifier (PCI ) of a high frequency cell, measurement time window information, mobility management reference signal information (Mobility Reference Signal, MRS), and a measurement report configuration. The measurement report configuration can be a measurement report period, a threshold to trigger a measurement report or the like.
Petition 870190072993, of 07/30/2019, p. 11/33
28/98 [0096] When intra-frequency measurement and / or inter-frequency measurement are configured for the terminal, a uniform RRM measurement time window can be configured for the terminal without considering a difference between different beams, a difference between different cells, and a difference between different carriers, thus reducing the complexity of detecting a beam and an MRS through the terminal, and also helping the terminal to save energy; or MRSs in positions of different sub-bands (Subband) on a carrier can be configured for the terminal. As shown in Figure 3, on a high frequency carrier, three different sub-bands are configured for the terminal to detect an MRS, thereby reducing MRS overloads and improving the accuracy of RRM measurement. The high frequency carrier in Figure 3 includes three sub-bands: a sub-band 1, a sub-band 2 and a sub-band 3.
[0097] Base station 100 sends a beam reference signal, in the form of a beam, used for RRM measurement to terminal 200. For example, base station 100 sends a beam reference signal to the terminal using antenna multiple inputs and multiple outputs. The MRS sequences of beam reference signals from different beams are the same, or the MRS sequences of beam reference signals from different beams may be different.
[0098] Terminal 200 receives the measurement configuration information and the beam reference signal that are sent by the base station 100, and terminal 200 measures, for example, perform RRM measurement on, the beam reference signal
Petition 870190072993, of 07/30/2019, p. 11/34
29/98 based on measurement configuration information. Base station 100 can send a plurality of beam reference signals to terminal 200. Terminal 200 can obtain a beam reference signal at the same time, or it can obtain a plurality of beam reference signals at the same time. Terminal 200 obtains a plurality of different or equal beam reference signals at different times. To be specific, terminal 200 obtains beam reference signals in the same cell, or obtains beam reference signals in different cells.
[0099] After obtaining a beam reference signal, the terminal measures the beam reference signals within a period of time, to obtain measurement values of the beam reference signals, and performs filtering on the signal measurement values beam reference to obtain a measurement result. The measurement results can be a cell measurement result, or a beam measurement result, or a cell measurement result and a beam measurement result. Optionally, the measurement result can be selected based on an indication of the type of measurement result sent by the base station. The measurement result type indication sent by the base station can instruct the terminal to report a cell measurement result or instruct the terminal to report a beam measurement result, or instruct the terminal to report a cell measurement result and a beam measurement result. For example, the measurement result type indication can instruct the terminal to send a cell measurement result, and the terminal must obtain the cell measurement result; or indication of the type of result of
Petition 870190072993, of 07/30/2019, p. 11/35
30/98 measurement can instruct the terminal to send a beam measurement result, and the terminal must obtain the beam measurement result.
[00100] The terminal 200 measures, based on the measurement configuration information sent by the base station 100, beam reference signals in the same cell or different cells obtained by the terminal 200, to obtain measurement values respectively corresponding to the plurality of signals different beam reference points. The terminal performs filtering on measured values that are obtained within a predefined period of time, to obtain a measurement result. The measurement result can be a cell measurement result or a beam measurement result, or a cell measurement result and a beam measurement result. Terminal 200 can send the measurement result in a form of measurement reports to base station 100, so that base station 100 selects an appropriate cell or downlink beam based on measurement reports, for communication with the terminal 200. Optionally, the measurement configuration information sent by base station 100 includes measurement result type indication information, used to instruct terminal 200 to send a cell measurement result, or a beam measurement result, or a cell measurement result and a beam measurement result at base station 100.
[00101] After measuring the beam reference signals obtained based on the measurement configuration information sent by the base station, to obtain the measurement values of the beam reference signals, terminal 200 needs
Petition 870190072993, of 07/30/2019, p. 36/115
31/98 perform filtering on the measured values, to obtain the measurement result. In a process in which the terminal communicates with the base station, it is very likely that the terminal will move with a user. Therefore, in the process where terminal 200 communicates with the base station, it is very likely that terminal 200 will obtain a beam reference signal in a moment, and can obtain a plurality of beam reference signals in a moment (for example, example, a multipath signal or a beam reference signal in a neighboring cell generated by the reflection of a beam reference signal received in a serving cell or otherwise). In addition, terminal 200 can obtain beam reference signals in the same cell or can obtain beam reference signals in different cells within a period of time.
[00102] Therefore, for the different cases that the terminal 200 finds, specifically, the measurement values of the beam reference signals can be filtered in the following ways:
(1) When the terminal obtains a beam reference signal at the same time, and the terminal obtains a plurality of beam reference signals at different times, in a process in which the terminal performs filtering at measured values respectively corresponding to a plurality of beam reference signals that are obtained within a first predefined time interval, the terminal obtains the measurement values respectively corresponding to the plurality of beam reference signals within the predefined time interval, and separately processes the values of measurement in a first predefined way to

32/98 obtain measurement results from the plurality of beam reference signals.
[00103] In the first predefined way, the measurement values respectively corresponding to a plurality of beam reference signals that are obtained within a predefined time interval can be averaged, that is, the measurement values corresponding to the plurality of beam reference signals are averaged, to obtain an average measurement value of the plurality of beam reference signals, the average measurement value can be used as a first measurement result of the plurality of beam reference signals, and the first measurement result can be used as a cell measurement result.
(2) When the terminal obtains a beam reference signal at the same time, and the terminal obtains a plurality of different beam reference signals at different times, in a process in which the terminal performs filtering at correspondingly measured values to a plurality of different beam reference signals that are obtained within a second predefined time interval, the terminal obtains the measured values respectively corresponding to the plurality of different beam reference signals within the second predefined time interval, processes separately the measured values in a second predefined way, to obtain a measurement result from the plurality of different beam reference signals, and you can use the measurement result as a cell measurement result.
[00104] When the second predefined way is used,
Petition 870190072993, of 07/30/2019, p. 38/115
33/98 is considered to be a difference between a plurality of different beam reference signals. For example, the same beam reference signals in the plurality of different beam reference signals are used as a category, so that the plurality of different beam reference signals can be classified into a plurality of categories, and measurement values. corresponding to beam reference signals of each category are averaged to obtain an average measurement value corresponding to this category of beam reference signals. In this way, mean measurement values corresponding to the plurality of categories of beam reference signals can be obtained respectively, and are used as a second measurement result of the plurality of different beam reference signals, and the second measurement result can be used as a result of beam measurement.
(3) When the terminal obtains a plurality of beam reference signals at the same time, and the terminal obtains a plurality of different beam reference signals at different times, in a process in which the terminal performs filtering on measured values respectively corresponding to a plurality of different beam reference signals that are obtained within a third predefined time interval, the terminal obtains the measured values respectively corresponding to the plurality of different beam reference signals within the third predefined time interval, processes the measured values separately in a predefined manner to obtain a measurement result from the plurality of different beam reference signals, and can use the measurement result as
Petition 870190072993, of 07/30/2019, p. 39/115
34/98 a cell measurement result.
[00105] The terminal can obtain a plurality of beam reference signals at the same time within the third predefined time interval. Therefore, the terminal obtains measurement values respectively corresponding to a plurality of beam reference signals that are obtained at each moment, and averages the measurement values of the plurality of beam reference signals at the same time, to obtain a value average measurement of the beam reference signals at the moment, to obtain average measurement values respectively corresponding to the plurality of beam reference signals at the various moments.
[00106] The terminal obtains average measurement values respectively corresponding to the plurality of beam reference signals at different times within the third predefined time interval, processes the average measurement values in the third predefined way, to obtain a third measurement result, and you can use the third measurement result as a cell measurement result.
[00107] In the third predefined way, mean measured values respectively corresponding to a plurality of beam reference signals at different times within a predefined time interval can be averaged to obtain a measurement result.
(4) When the terminal obtains a plurality of beam reference signals at the same time, and the terminal obtains a plurality of different beam reference signals at different times, in a process in which the terminal performs filtering on measured values respectively corresponding to a plurality of different
Petition 870190072993, of 07/30/2019, p. 40/115
35/98 beam reference that are obtained within a predefined time interval, the terminal obtains measured values respectively corresponding to a plurality of different beam reference signals within a fourth predefined time interval, processes the measured values separately in a fourth predefined way, to obtain a measurement result from the plurality of different beam reference signals, and you can use the measurement result as a cell measurement result.
[00108] The terminal can obtain a plurality of beam reference signals at the same time within the fourth predefined time interval. Therefore, the terminal obtains measurement values respectively corresponding to a plurality of beam reference signals obtained at each moment, and obtains a maximum measurement value of the beam reference signals at the same time, to obtain maximum measurement values respectively corresponding to the plurality of beam reference signals at various times.
[00109] The terminal obtains the maximum measurement values respectively corresponding to the plurality of beam reference signals at various times within the fourth predefined interval, and processes the maximum measurement values in a predefined way, to obtain a measurement result.
[00110] In the fourth predefined way, the maximum measured values respectively corresponding to a plurality of beam reference signals at various times within a predefined time interval can be averaged, to obtain a fourth result of
Petition 870190072993, of 07/30/2019, p. 41/115
36/98 measurement, and the fourth measurement result can be used as a cell measurement result.
[00111] Furthermore, if the plurality of beam reference signals obtained by the terminal at the same time are the same beam reference signals, after the maximum measurement values corresponding to the various moments respectively are obtained, in a fifth predefined way, the beam reference signals at different times can be distinguished from each other, maximum measured values respectively corresponding to the same beam reference signals at the various moments are averaged, to obtain average measurement values corresponding to the various types of signal signals beam reference, the average measurement values are used as a fifth measurement result of the plurality of different beam reference signals, and the fifth measurement result is used as a beam measurement result.
[00112] Certainly, if a difference between a plurality of different beam reference signals is considered, to be specific, the plurality of beam reference signals is classified into a plurality of different beam reference signals, maximum measurement values respectively corresponding to various types of beam reference signals can be determined at maximum measured values respectively corresponding to various moments, the measured values can be used as measurement results of the plurality of different beam reference signals, and the results of measurement can be used as a result of beam measurement.
(5) When the terminal obtains a plurality of

37/98 beam reference at the same time, and the terminal obtains a plurality of beam reference signals at different times, in a process in which the terminal performs filtering on measured values respectively corresponding to a plurality of reference reference signals. beam that are obtained within a fifth predefined time interval, the terminal obtains the measured values respectively corresponding to the plurality of beam reference signals within the fifth predefined time interval, separately processes the measured values in a predefined way, for obtain measurement results from the plurality of beam reference signals, and can use the measurement results as a cell measurement result.
[00113] The terminal can obtain one or more beam reference signals at the same time within the fifth predefined time interval. Therefore, the terminal obtains measurement values of beam reference signals that are obtained at various times. If the terminal obtains a plurality of beam reference signals at a time, the terminal averages the measured values respectively corresponding to the plurality of beam reference signals, to obtain an average measurement value at the same time. If the terminal obtains a beam reference signal at the same time, the terminal uses a measurement value of the beam reference signal as an average measurement value at the moment, to obtain an average measurement value of a reference reference signal. beam at every moment. Therefore, in a sixth predefined way, average measurement values corresponding to several moments respectively can be averaged to obtain a sixth measurement result
Petition 870190072993, of 07/30/2019, p. 43/115
38/98 of the plurality of beam reference signals within the fifth predefined time interval, and the sixth measurement result can be used as a cell measurement result.
(6) When the terminal obtains a plurality of beam reference signals at the same time, and the terminal obtains a plurality of beam reference signals at different times, in a process in which the terminal performs filtering on measured values respectively corresponding to a plurality of beam reference signals that are obtained within a predefined time interval, the terminal obtains measured values respectively corresponding to a plurality of beam reference signals within a sixth predefined time interval, and processes separately the measured values in a seventh predefined way, to obtain measurement results from the plurality of beam reference signals.
[00114] The terminal can obtain one or more beam reference signals at the same time within the sixth predefined time interval. Therefore, the terminal obtains measurement values of beam reference signals that are obtained at various times. If the terminal obtains a plurality of beam reference signals at a time, the terminal obtains a maximum measured value of measured values respectively corresponding to the plurality of beam reference signals, to obtain a maximum measured value at the same time. If the terminal obtains a beam reference signal at the same time, the terminal uses a measurement value of the beam reference signal as a maximum measurement value at the moment, so values of
Petition 870190072993, of 07/30/2019, p. 44/115
39/98 maximum measurements corresponding to the beam reference signals respectively can be obtained at various times. Therefore, in the seventh predefined way, the maximum measured values respectively corresponding to several moments can be averaged, to obtain a seventh measurement result of the plurality of beam reference signals within the sixth predefined time interval, and the seventh result measurement can be used as a result of cell measurement.
[00115] Furthermore, if a difference is considered between a plurality of different beam reference signals, that is, the plurality of beam reference signals is classified into a plurality of different beam reference signals, the measurement values respectively corresponding maximum values for several categories of beam reference signals can be determined, in a predefined eighth way, at maximum measured values corresponding to various moments respectively, the measured values can be used as an eighth measurement result of the plurality of signals different beam reference points, and the eighth measurement result can be used as a beam measurement result.
[00116] In the first way predefined to the eighth way predefined in this modality of that order, the measured values of the beam reference signals can be averaged and are filtered in the previous mode or a maximum value of the measured values of the reference signals beam can be obtained in the previous mode. Arithmetic calculation or weighted calculation can be used as needed to obtain an average value. Obtaining a weight
Petition 870190072993, of 07/30/2019, p. 45/115
40/98 or average coefficient through weighted calculation can be configured or predefined. See formula (1) and a corresponding modality in the previous modality. In this modality of this request, an average value or a maximum value of measurement values of different beam reference signals can be obtained.
[00117] It should be noted that, in this embodiment of this application, the plurality of beam reference signals are two or more beam reference signals.
[00118] In a modality provided in this order, Figure 15 is a schematic diagram when the terminal performs the RRM measurement. In this modality of this order, in a process in which the terminal performs filtering on a measurement value of a obtained beam reference signal, the following way of calculating the average can be specifically used, but this modality of this order is not limited to this .
[00119] The terminal performs Layer 1 filtering (that is, a physical layer) (Layer 1 filtering) on one or more physical layer measurement values based on a specific algorithm (such as arithmetic average or weighted average), and transfers a result obtained through filtering to Layer 3 (namely, an RRC layer) to perform Layer 3 filtering (Layer 3 filtering). A form filtering algorithm:
F _n = (1 - a) · F _n _, + a M
M _n is a most recent measurement value received from a physical layer; F _n is an updated measurement value and is used to evaluate a measurement reporting criterion; F _n - i is a previous measurement result; Fo = Mi is a first value
Layer 3 and shown in the following, where
Petition 870190072993, of 07/30/2019, p. 46/115
41/98 measurement received from the physical layer; and a = 1/2 (k / 4), and k is a filter coefficient, and is sent by the base station to the terminal using the corresponding measurement configuration information.
[00120] The terminal performs the evaluation based on a measurement result obtained through Layer 3 filtering and the measurement reporting criterion, and determines whether a measurement result reporting condition is met; and if the measurement result report condition is met, the terminal sends an RRM measurement report to the base station including the measurement result obtained through Layer 3 filtering.
[00121] When using Layer 3 filtering, the terminal determines, based on different measurement scenarios, time intervals necessary for different filtering processes. For example, during intrafrequency measurement, a filter coefficient value k is 200 ms; and when the value of k is 0, it indicates that no Layer 3 filtering is performed.
[00122] According to the previous modality provided in that order, after obtaining a measurement result, if the measurement result satisfies a configuration condition, a measurement report is generated using the measurement result, and the terminal sends the report the base station. The configuration condition can be set as needed, for example, a receive power threshold is set. In addition, when the terminal measures a beam reference signal sent by the base station, in this mode, different sampling periods and different amounts of sampling points can be used in
Petition 870190072993, of 07/30/2019, p. 47/115
42/98 different measurement models, to satisfy different measurement requirements. A measurement result includes a cell measurement result and / or a beam measurement result. The base station can select a cell serving for the terminal based on the cell measurement result, and can select a beam signal for communication to the terminal based on the beam measurement result.
[00123] The cell measurement result may include a serving cell measurement result and / or a neighbor cell measurement result. When a measurement result

different measurement reporting modes are configured for terminal 200. As shown in Figure 4, terminal 200 can send, to a master eNB (MeNB) 300, a measurement report including a cell measurement result, and the MeNB 300 determines , based on the cell measurement result, if you perform a transfer between secondary eNBs or change a secondary eNB.
[00125] The terminal sends, to a secondary eNB (SeNB) 400, a measurement report including a beam measurement result, and the SeNB 400 selects, based on the beam measurement result, a candidate beam applicable to the communication with terminal 200. Alternatively, terminal 200 sends a measurement report to a SeNB 400
Petition 870190072993, of 07/30/2019, p. 48/115
43/98 including a cell measurement result, so that the SeNB 400 determines, based on the cell measurement result, whether to perform a transfer between secondary eNBs.
[00126] When the base station obtains the measurement report sent by the terminal, the base station sends measurement configuration information to the terminal based on the measurement report. While receiving the measurement configuration information, the terminal continues to obtain beam reference signals sent from the base station. The terminal first determines a set of beam reference signal measurements of the beam reference signals based on the measurement configuration information, then determines an active set of beam signals in the set of beam reference signal measurements, and uses one or more beam reference signals having optimal measurement results on the active set of beam reference signals as target beam reference signals. The terminal sends a measurement result, in the form of a measurement report, corresponding to the target beam reference signal to the base station, so that the base station can use the target beam reference signal as a candidate beam for communication with the terminal.
[00127] To describe, in detail, how a terminal measures a beam reference signal based on measurement configuration information sent by a base station, so that the base station uses, based on a measurement report sent by the terminal , a target beam reference signal selected as a candidate beam for communication with the terminal, in another mode provided
Petition 870190072993, of 07/30/2019, p. 49/115
44/98 in that order, as shown in Figure 5, the following steps can be included.
[00128] Step 1001: The base station sends measurement configuration information to the terminal.
[00129] The measurement configuration information may include one or a combination of several of the following information: information on a set of beam measurements including one or more beam reference signals, a measurement set measurement period, a period active set measurement, beam configuration information, information about a first threshold used to determine an active beam set, and information about a second threshold used to determine an optimal candidate beam (the values of the first threshold and the second threshold are not are limited). Optionally, the measurement configuration information may further include measurement result type indication information, used to instruct the terminal 200 to send a cell measurement result, or a beam measurement result, or a measurement measurement result. cell and a beam measurement result for base station 100.
[00130] Step 1002: The base station sends a beam reference signal to the terminal.
[00131] The beam measurement set can include all beams or some beams in a particular cell or all beams or some beams in a plurality of beam reference signal cells. The same cell can include coverage of beams sent by a plurality of different TRPs or the same TRP; or different beam measurement sets can be maintained, respectively,
Petition 870190072993, of 07/30/2019, p. 50/115
45/98 for a serving cell and a neighboring cell.
[00132] The beam configuration information may include one or a combination of several of the following information: beam identifier information (beam identities or beam indexes) of one or more beams, a reference signal (RS), information of time-frequency resources, and antenna port information.
[00133] The measurement set measurement period is used by the terminal to measure each beam in the measurement set, and to generate or update the active beam set based on a measurement result. The active set measurement period is used by the terminal to measure each beam in the active beam set, to obtain a candidate beam for communication with the terminal. Generally, the measurement set measurement period is greater than or equal to the active set measurement period. When a specified time for the measurement set measurement period or the active set measurement period is reached, the terminal can perform the measurement for a period of time and, after the period of time ends, period delay is restarted . The measurement set measurement period or the active set measurement period can also be used as a time for the terminal to maintain or update the beam measurement set or the active beam set. Within a time corresponding to the measurement period of the set of measurements or the measurement period of the active set, the terminal measures different sets of beams.
[00134] Step 1003: The terminal measures each beam in a measurement set within a first measurement set period based on the configuration information
Petition 870190072993, of 07/30/2019, p. 51/115
46/98 measurement, to obtain a first measurement result.
[00135] The terminal detects and measures each beam in the beam measurement set based on the measurement period of the measurement set, and selects, based on a measurement result and the first threshold, one or more beams from the beams , as the active bundle of beams. The terminal can update the active set of beams within a next measurement set measurement period or a subsequent measurement set measurement period, because the measurement result may change.
[00136] Step 1004: The terminal determines an active set in the measurement set based on the first measurement result, and measures each beam in the active set, to obtain a second measurement result.
[00137] The terminal detects and measures each beam in the active beam set based on the measurement period of the active set, and selects one or more beams from the beams based on a measurement result and the second threshold. For example, the terminal selects one or more optimal beams based on the threshold in the measurement configuration (or a predefined number of reported beams). The terminal reports information about the one or more selected beams and the measurement result for the base station, so that the base station can use the one or more beams as candidate beams for communication with the terminal, for example, a SeNB determines a beam in which a physical downlink control channel (PDCCH) is sent to the terminal.
[00138] Step 1005: The terminal determines a target beam reference signal in the active set based on the second measurement result.
Petition 870190072993, of 07/30/2019, p. 52/115
47/98 [00139] An optimal beam selected by the terminal within the next active set measurement period or a subsequent active set measurement period can vary, because an active set can vary, and a beam with an optimal measurement result in the active set can change.
[00140] Step 1006: The terminal sends information, in the form of a measurement report, corresponding to the target beam reference signal to the base station.
[00141] Step 1007: The base station selects, based on the measurement report sent by the terminal, one or more beams having measurement results as candidate beams for communication with the terminal.
[00142] When the base station needs to update the beam measurement set, the base station sends new configuration information to the terminal, performs step S1001, and configures a new beam measurement set and other parameter information for the terminal .
[00143] In the previous steps, beams in the beam measurement set and the active beam set may not belong to the same cell, or they may be intra-frequency beams, or they may be inter-frequency beams.
[00144] It should be noted that when the measurement result of the beam reference signal is obtained, the manner described above can be used, and the details are not described here again.
[00145] The previous steps are applicable to a dual or multi-connectivity architecture. For example, a set of high frequency SeNBs includes a plurality of SeNBs (a first SeNB and another SeNB) or a plurality of TRPs, the beam measurement set or the
Petition 870190072993, of 07/30/2019, p. 53/115
48/98 active beam set includes information about beams from the plurality of SeNBs or the plurality of TRPs, and the terminal sends the measurement report to a MeNB or the first SeNB, to select the first SeNB or another SeNB or a set SeNBs or information about a candidate beam from it.
[00146] The method of measuring radio resources provided in this modality of this application is applicable to the measurement of RRM in a high frequency cell or similar, so that in a scenario in which the high frequency cell is implanted, a cell of appropriate high frequency and / or an appropriate downlink beam is / is selected for the terminal for communication and, in addition, an appropriate beam can be selected for the terminal for communication, to support the mobility of the terminal, ensure continuity of communication , and reduce the likelihood of a communication disruption.
[00147] Furthermore, in this modality of this request, for the filtering of LI / L3 of a downlink beam independent measurement model (to be specific, a downlink beam feature is not considered) and a specific downlink beam measurement, different measurement requirements (such as a period and number of sampling points) can be used, thus reducing processing overheads of the terminal, and also ensuring different measurement accuracy requirements.
[00148] In the dual connectivity architecture, based on the independent downlink beam measurement model (to be specific, a beam feature)
Petition 870190072993, of 07/30/2019, p. 54/115
49/98 downlink is not considered), information about a beam from the SeNB is hidden from the MeNB, thereby simplifying a cell-specific mobility management process, and reducing signaling overloads from a measurement report.
[00149] Based on the specific downlink beam measurement model (to be specific, a downlink beam feature is considered), SeNB can more finely manage different beams, and always selects an optimal candidate beam for the communication with the UE, thereby improving communication reliability and a transmission rate during communication.
[00150] Furthermore, in this mode of this order, the terminal autonomously maintains the active bundle of bundles, and measures information about a bundle in the bundle of active bundles based on the measurement period of the bundle, so that measurement overloads and terminal processing is reduced, and signaling overheads required by the base station to frequently configure the active set of beams for the terminal are reduced; and being considered as beam-specific mobility management controlled by the terminal, network processing is simplified and a delay is reduced. The terminal selects information about one or more optimal beams, and reports the information to the base station, so that the base station always selects a downlink beam most appropriate for communication with the terminal.
[00151] In another modality provided in this order, a method of radio link monitoring (RLM) is also provided in a high frequency cell.
Petition 870190072993, of 07/30/2019, p. 55/115
50/98 [00152] In LTE, a process in which the terminal executes RLM is as follows: A physical layer of the terminal determines, by measuring a specific CRS cell reference signal and / or measuring a reception condition of a channel of PDCCH physical downlink control, an out of sync indication or a sync indication (in sync) is sent to a higher level protocol layer. When a number of downlink out-de-synchronization indications sent by the physical layer and received continuously by the terminal is equal to a predefined value, a timer is started. During execution, if a predefined amount of downlink synchronization indications sent by the physical layer is received continuously, the timer is interrupted, and indicates that a radio link has already been recovered. If the timer expires, the terminal considers a radio link failure (RLF), and triggers an RRC connection reestablishment process. In addition, if a Radio Link Control (RLC) protocol data unit reaches a maximum number of retransmissions, or a failure in the random access process occurs, a radio link failure is also determined to occur. For example, the timer can be a T310 timer.
[00153] Because RLM monitoring is performed very frequently (sampling points need to be monitored at relatively short intervals), if the terminal always detects all the beams in a cell, the processing load of the terminal is very high, and an operation of normal communication can be affected. To reduce the overhead of executing RLM through the terminal, in this
Petition 870190072993, of 07/30/2019, p. 56/115
51/98 modality of this request, during the RLM of a high frequency cell, the following steps can be included: The terminal determines an optimum downlink beam using a downlink link specific RRM measurement method in the previous modality; the terminal performs RLM radio link monitoring on the optimal downlink beam; and when the optimum downlink beam changes, the terminal performs an RLM process based on a new optimum downlink beam. For example, in a first phase, the terminal performs RLM based on a BI beam on beam reference signals; and in a second phase, the terminal performs the RLM based on a B4 beam in the beam reference signals.
[00154] When the terminal performs RLM on a target beam reference signal within a predefined time interval, the terminal determines whether the target beam reference signal satisfies an RLF condition. If the terminal determines that the target beam reference signal satisfies the RLF condition, the terminal triggers a Radio Resource Control connection reestablishment process, to be specific, sends a Radio Control link reestablishment request message. Radio resources for the base station.
[00155] In addition, when a measurement result of the target beam reference signal is less than a predefined third threshold, the terminal selects a beam in which a beam reference signal in an active set of beam reference signals is located, to perform RLM; and the terminal can perform parallel RLM on a plurality of beams.
Petition 870190072993, of 07/30/2019, p. 57/115
52/98 [00156] Alternatively, the terminal executes the RLM in
all beams at the active set of signals in reference in beam. [00157] The terminal selects each signal in reference in beam based in descending order in results in
measurement of beam reference signals in the active set of beam reference signals, to perform RLM, and when a measurement result of a beam reference signal having an upper beam reference measurement result is less than one preset third threshold, reselects a beam reference signal having a lower beam reference signal measurement result, to perform RLM.
[00158] When it is determined that the target beam reference signal and a beam reference signal different from the target beam reference signal both satisfy the RLF condition, the terminal triggers the Radio Resource Control connection reestablishment process .
[00159] To solve a related technical problem and describe, in detail, the procedure performed in the previous modality, in another modality provided in that order, with reference to the previous modality, a method of measuring radio resources is provided. The method is applied to a terminal and, as shown in Figure 6, the method can include the following steps.
[00160] Step S110: The terminal obtains the first measurement configuration information.
[00161] The terminal obtains the first measurement configuration information sent by a base station. The first measurement configuration information includes one or
Petition 870190072993, of 07/30/2019, p. 11/115
53/98 a combination of several of the following: a measurement frequency, a measurement bandwidth, an intra-frequency measurement configuration, an inter-frequency measurement configuration, a physical cell identifier (PCI) of a high frequency, measurement time window information, mobility management reference signal information (Mobility Reference Signal, MRS), and a measurement report configuration. The measurement report configuration can be a measurement report period, a threshold to trigger a measurement report or the like.
[00162] Step S120: The terminal obtains beam reference signals sent by one or more base stations.
[00163] The beam reference signal is a beam reference signal sent by the base station to the terminal using a massive multiple input and multiple output antenna. The MRS sequences of beam reference signals from different beams are the same, or the MRS sequences of beam reference signals from different beams may be different.
[00164] When the terminal is in an intermediate position of a cell, the terminal can obtain a beam reference signal sent by a base station serving the cell. During the movement of the terminal, for example, in a process in which the terminal moves from the middle position of the cell to a position between two cells, it is very likely that the terminal will obtain beam reference signals sent by one or more base stations, to be specific, the terminal obtains beam reference signals sent in one or more cells.
Petition 870190072993, of 07/30/2019, p. 59/115
54/98 [00165] Step S130: The terminal measures the beam reference signals based on the first measurement configuration information, to obtain measurement values of the beam reference signals.
[00166] The terminal receives the measurement configuration information and the beam reference signal that are sent by the base station. Terminal measurements, for example, perform RRM measurement on, the beam reference signal based on the measurement configuration information. The terminal measures at least one received beam reference signal. In this embodiment, an example in which the terminal receives a plurality of beam reference signals sent by the base station is used for description.
[00167] The terminal measures each of the received beam reference signals, to obtain a measurement value for each measurement sample, performs filtering on the measured values of the beam reference signals based on the measured values, and can calculate a high frequency cell measurement result based on the measurement results of the beam reference signals. The terminal generates a measurement report using the measurement results, and sends the measurement report to the base station, so that the base station selects a high frequency cell or an appropriate downlink beam based on the measurement report, for communication with the terminal.
[00168] A specific way of measuring, by the terminal, the beam reference signal sent by the base station is already described in detail in the previous related modality. For details, see the previous modality, and the details are not described here again.
Petition 870190072993, of 07/30/2019, p. 60/115
55/98 [00169] Step S140: The terminal performs filtering on the measured values of the beam reference signals, to obtain a measurement result.
[00170] The measurement result includes a cell measurement result and / or a beam of measurement result.
[00171] In a process of sending the beam reference signal to the terminal by the base station, there may be an unstable factor, such as a loss of trajectory. Consequently, the measured values obtained from one or more beam reference signals cannot represent a measurement result for all beam reference signals. Therefore, measurement values of beam reference signals within a predefined time period need to be filtered, to obtain a measurement result that can represent the beam reference signals obtained within the predefined time period, so that the result measurement has greater reference and use value.
[00172] The terminal performs Layer 3 filtering, that is, physical layer, MAC layer, and Radio Resource Control (RRC) layer filtering, in the measurement values of the beam reference signal.
[00173] In addition, the terminal generates the measurement report using the measurement result, and sends the measurement report to the base station.
[00174] The measurement report can include a cell measurement report and a beam measurement report. The base station includes a MeNB master eNB and a SeNB secondary eNB. The terminal sends the cell measurement report to the MeNB master eNB. The terminal sends the beam measurement report to the secondary eNB SeNB.
Petition 870190072993, of 07/30/2019, p. 61/115
56/98 [00175] The beam reference signals are beam reference signals in the same cell obtained by the terminal, or the beam reference signals are beam reference signals in different cells obtained by the terminal. Therefore, to provide more details for the method in Figure 6, as shown in Figure 7, in another embodiment provided in that application, step S140 can further include the following steps.
[00176] Step S141: The terminal obtains measured values respectively corresponding to a plurality of beam reference signals that are measured within a predefined time interval.
[00177] Step S142: The terminal processes the measurement values of the plurality of beam reference signals in a predefined way, to obtain the measurement results.
[00178] The terminal can obtain a beam reference signal at the same time, or the terminal can obtain a plurality of beam reference signals at the same time. At a plurality of times within a predefined period of time, the terminal can obtain beam reference signals in the same cell, or it can obtain beam reference signals sent in different cells; and the terminal measures the beam reference signals obtained, to obtain measured values respectively, and then performs filtering on the measured values, to obtain the measurement results. A detailed process of filtering the measured values by the terminal is already registered in the
modality previous, and details not are described on here again. [00179] To describe, in detail, how a terminal give me
Petition 870190072993, of 07/30/2019, p. 62/115
57/98 a beam reference signal based on measurement configuration information sent by a base station, so that the base station uses, based on a measurement report sent by the terminal, a target beam reference signal selected as a candidate beam for communication with the terminal, in another mode provided in that order, as shown in Figure 8, the following steps can be included.
[00180] Step S810: The terminal obtains second measurement configuration information.
[00181] The measurement configuration information may include one or a combination of several of the following information: information on a set of beam measurements including one or more beam reference signals, a measurement set measurement period, a period active set measurement, beam configuration information, information on a first threshold used to determine an active beam set, and information on a second threshold used to determine an optimal candidate beam.
[00182] Step S820: The terminal determines a set of beam reference signal measurements from beam reference signals based on the second measurement configuration information.
[00183] The base station can send a plurality of beam reference signals to the terminal. Therefore, the terminal can determine, based on the second measurement configuration information sent by the base station, a set of beam measurements that need to be measured on the plurality of beam reference signals.
Petition 870190072993, of 07/30/2019, p. 63/115
58/98 [00184] Step S830: The terminal measures a beam reference signal in the beam reference signal measurement set, to determine an active set of beam reference signals.
[00185] Specifically, the second measurement configuration information includes a first predefined threshold. Therefore, to provide more details about the method in Figure 8, as shown in Figure 9, in another embodiment provided in that application, step 730 may further include the following steps.
[00186] Step 831: The terminal measures the beam reference signal in the set of beam reference signal measurements within a first predefined period, to obtain a measurement result within the first predefined period.
[00187] Step 832: The terminal uses a beam reference signal whose measurement result within the first predefined period is greater than a first predefined threshold as the active set of beam reference signals.
[00188] The first predefined period is equivalent to the measurement period of the set of measurements in the previous modality, and a second predefined period is equivalent to the measurement period of the active set in the previous modality.
[00189] The terminal measures the beam reference signal in the beam reference signal measurement set, to obtain the measurement value of the beam reference signal, and selects the active set of beam reference signals from the set of measuring beam reference signals based on the first threshold on the second
Petition 870190072993, of 07/30/2019, p. 64/115
59/98 measurement configuration information. For example, a beam reference signal whose transmission power is greater than a threshold in the set of beam reference signal measurements is determined as the active set of beam reference signals.
[00190] The second measurement configuration information includes a second predefined threshold. To provide more details for the method in Figure 9, in another modality provided in that order, the following steps can still be included:
[00191] Step 833: The terminal measures a beam reference signal in the active set of beam reference signals within a second predefined period, to obtain a measurement result within the second predefined period.
[00192] Step 834: The terminal uses a beam reference signal whose measurement result within the second predefined period is greater than the second predefined threshold as a target beam reference signal.
[00193] To select even more one or more beam reference signals having optimal measurement results from the active set of beam reference signals as candidate beams, the terminal uses, based on the second predetermined threshold, one or more signals beam reference having maximum measurement values in the active set as one or more target beam reference signals, and sends the measurement result and information corresponding to the target beam reference signal to the base station, so that the station base uses the target beam reference signal as a candidate beam for communication with the terminal.
[00194] According to the method of measuring resources of
Petition 870190072993, of 07/30/2019, p. 65/115
60/98 radio provided in this modality of that request, the terminal receives the first measurement configuration information sent by the base station, and measures the beam reference signals based on the first measurement configuration information, to obtain the measurement values of the beam reference signals; and the terminal performs filtering on the measurement values of the beam reference signals, to obtain the measurement results. The measurement results can include the cell measurement result and the beam measurement result. The base station can determine, based on the measurement results, whether to perform a handover transfer between cells serving or switch a beam for communication with the terminal. The terminal measures and performs filtering on the beam reference signal that is sent in the form of a beam by the base station, thereby greatly reducing signaling overheads from the terminal and the base station, avoiding a problem of user communication interruption which is caused by a relatively high handover failure rate from the terminal, and further reducing a communication delay between the terminal and the base station.
[00195] Based on the previous descriptions of the method modalities, a person skilled in the art can clearly understand that this application can be implemented by software in addition to a necessary universal hardware platform or just by hardware. In most circumstances, the former is a preferred implementation. Based on this understanding, the technical solutions of that order essentially, or the part that contributes to the prior art, can be implemented in the form of a

71/98
Therefore, to compensate for a loss of high frequency signal path, to improve the reliability of service transmission, generally, a plurality of beams (beam) are configured for the terminal to simultaneously perform data transmission.
[00217] However, based on the fact that a high frequency signal has intrinsic characteristics, such as low penetration and fast attenuation when encountering an obstruction, by a terminal, although a large number of beams are configured for the terminal and are active, when the terminal communicates with the base station using the configured beams, if the signals from some beams suddenly attenuate, when the terminal and the base station continue to keep the beams in an active state, a waste of network resources is caused, and power consumption of the terminal is also greatly increased.
[00218] Therefore, when the terminal communicates with the base station using a plurality of beams, if the signal quality of some beams suddenly deteriorates, to avoid a problem such as a waste of network resources that is caused when the terminal and the base station continues to maintain the beams, the modalities of this request also provide a method of selecting radio resources and a device.
[00219] In the modalities provided in this application, a beam is a spatial resource to perform the communication using a high frequency signal. A base station can communicate with different terminals using the same beam or a terminal can communicate with a base station using one or more beams. The solutions provided in the modalities of this
Petition 870190072993, of 07/30/2019, p. 77/115
72/98 order are also applicable to another space resource, such as a port.
[00220] In a first project way provided in a modality of this request, the terminal can disable or exclude a beam that does not satisfy the communication quality.
[00221] In this mode, the terminal can obtain a result of measuring a beam. The terminal can obtain measurement results from one or more beams. The one or more beams are beams in an active state for the terminal.
[00222] For the terminal, states of a configured beam can be classified into an active state and a disabled state. A beam in the active state can also be referred to as an active beam, and a beam in the disabled state can also be referred to as a disabled beam. Information about a deactivated beam can be retained at the terminal or at the base station. For the terminal, a beam in the active state can be used by the terminal and the base station to perform data transmission, and a beam in the disabled state is not used by the terminal and the base station to perform data transmission. An active beam can become a deactivated beam by a deactivation operation, and a deactivated beam can become an active beam by an activation operation. A person skilled in the art must learn that the active state and the disabled state of a beam are specific to a dimension of a terminal. For example, a beam can be a disabled beam for one terminal and it can be an active beam for another terminal. For another example, that the base station disables a beam means that the base station sets a beam state to disable for one terminal, without affecting a beam state for another
Petition 870190072993, of 07/30/2019, p. 78/115
73/98 terminal.
[00223] For the terminal, a non-configured beam means that the terminal does not store information related to the beam.
[00224] The terminal can obtain a measurement result in a plurality of ways. For example, the terminal can measure a beam to obtain a measurement result, or obtain measurement results from one or more beams from another terminal, or it can obtain measurement results from one or more beams from the base station. The measurement results of one or more beams obtained from the base station can be measured by the base station or can be measured by another terminal. Optionally, the base station can indicate, for the terminal, a beam that needs to be measured. Optionally, the terminal can voluntarily select a beam that needs to be measured. The measurement result can be used to assess the communication quality of the beam. For example, a beam signal quality measurement result can be used as a measurement result or as part of the measurement result. For another example, a measurement result of a loss of beam path can be used as a measurement result or as part of the measurement result.
[00225] After obtaining the measurement results of one or more beams, the terminal can determine whether the measurement results of the one or more beams satisfy a first quality condition, to be specific, determine whether the beam meets a quality requirement of communication. The first quality condition is a condition used to determine whether a beam meets the communication quality requirement, and a beam satisfying the first quality condition.
Petition 870190072993, of 07/30/2019, p. 79/115
74/98 quality can be considered as a beam that does not satisfy the communication quality requirements. For example, the first quality condition may be that the signal quality is less than a threshold, or the signal quality is less than a threshold within a period of time, or an amount of times that the signal quality is lower that a threshold within a period of time is greater than a predefined number of times. For another example, the first quality condition may be that a loss of beam path is greater than a threshold, or a loss of beam path is greater than a threshold within a period of time or an amount of times a loss beam path is greater than a threshold within a period of time is greater than a predefined number of times. The content of the first quality condition can be formulated as required, and the content of the first quality condition is not limited in that order. The first quality condition can be sent by the base station to the terminal or it can be specified in a communication standard. The first quality condition can also be implicitly indicated. For example, if it is specified in a standard that the quality requirement is that the signal strength is greater than or equal to a threshold A, it can be considered that it implies that the first quality condition is that the signal strength is less that threshold A.
[00226] After determining one or more beams that do not satisfy the communication quality requirement, the terminal can send first indication information to the base station. The first indication information is
Petition 870190072993, of 07/30/2019, p. 80/115
75/98 used to instruct the deactivation or exclusion of one or more beams that do not satisfy the communication quality requirement. Optionally, the terminal can voluntarily disable or exclude the one or more beams that do not satisfy the communication quality requirement. After deactivating or deleting one or more beams that do not meet the communication quality requirement, the terminal does not communicate with the base station using one or more beams that do not meet the communication quality requirement.
[00227] A bit can be used to indicate a state of a beam at the terminal or at the base station, and the beam can be disabled by changing a bit value. The beam can be excluded by excluding a beam context, to be specific, information about the beam stored in the terminal or the base station is excluded.
[00228] After receiving the first indication information sent by the terminal, the base station can deactivate or exclude one or more beams that do not satisfy the communication quality requirement. During communication with the base station, the terminal disables or excludes one or more beams that do not satisfy the communication quality requirement, so that if the beam signals for communication between the terminal and the base station suddenly attenuate, or something similar , a problem of wasted network resources that is caused when communication is still performed using beams that do not meet the communication quality requirement can be avoided, and a problem of a huge increase in power consumption caused when the terminal still performs communication using relatively quality communication beams
Petition 870190072993, of 07/30/2019, p. 81/115
76/98 low can be avoided.
[00229] The terminal can send the first indication information to the base station in a plurality of ways.
[00230] In an optional first way, the terminal can send the first indication information using the beam that does not satisfy the communication quality requirement. Optionally, the first indication information can be indication of deactivation information or indication of exclusion information. After receiving the first indication information on the beam, the base station can learn that the beam needs to be deactivated or deleted.
[00231] The first indication information can be implemented in a plurality of ways. In an optional way, the beam identification information that does not satisfy the communication quality requirement is used as the first indication information or a part of the first indication information. After receiving the beam identifier information on the beam, the base station can immediately disable or delete the beam. In another optional way of it, the beam quality information that does not satisfy the communication quality requirement is used as the first indication information or a part of the first indication information. For example, a CQI0 (channel quality indicator) = can be sent to the base station, and after receiving the CQI = 0 on the beam, the base station can immediately disable or delete the beam. It can be considered that the CQI = 0 indicates poor quality of beam communication. In another optional way of it, a deactivation or exclusion indicator is used as the first indication information or a part of the
Petition 870190072993, of 07/30/2019, p. 82/115
77/98 first indication information. The activation indication information or the exclusion indication information can be represented using a bit.
[00232] In an optional second way, the terminal can send the first indication information using a beam other than the beam that does not satisfy the communication quality requirements. When the first indication information is sent on the other beam, the identification information of the beam that does not satisfy the communication quality requirement can be used as the first indication information or a part of the first indication information. Optionally, the beam quality information that does not satisfy the communication quality requirement can be used as part of the first indication information. Optionally, the deactivation indication information or the exclusion indication information can be used as part of the first indication information.
[00233] In an optional third way, the terminal can send the first indication information to the base station using a macro network or a low frequency network. Sending information via a macro network or a low frequency network can be understood as sending the first indication information to the base station, using a network, for example, an NR (new radio) network (a 5G network for short), an LTE network, a UMTS network or a GSM network. For an implementation of the first indication information, refer to the second optional way above, and the details are not described here again. Specifically, the terminal can send the first indication information using a MAC layer or an RRC layer, to send the
Petition 870190072993, of 07/30/2019, p. 83/115
78/98 first indication information for the base station using the macro network or the low frequency network.
[00234] After the terminal sends the first indication information to the base station, the base station can disable or delete the beam that does not meet the communication quality requirement, to be specific, the base station can stop communicating with the terminal using the beam. After sending the first indication information to the base station, the terminal can stop monitoring the beam. Optionally, after receiving feedback from the first indication information that is sent by the base station, the terminal can stop monitoring the beam. The return information can carry the disabled or deleted beam identifier information, and the beam identifier information includes at least one of a beam identifier, a beam antenna port identifier, or a beam reference signal, or other identifying information.
[00235] Thus, if the base station is subject to external interference, or something similar, since the base station does not receive the first indication information sent by the terminal and continues to send data to the terminal using the beam, a problem of a data loss that is caused because the terminal prematurely interrupts the beam monitoring can be avoided.
[00236] Due to the fact that a high frequency signal has a relatively low penetration, rapid attenuation of the signal quality when it encounters an obstruction and the like in the previous modality, since there is a problem like the attenuation of a beam signal to
Petition 870190072993, of 07/30/2019, p. 84/115
79/98 communication between the terminal and the base station, the terminal can send the first indication information to the base station, to instruct the base station to disable or exclude the beam that satisfies the first quality condition. For example, during the movement of the terminal, if the terminal enters a blocked area, some communication beams between the terminal and the base station will be blocked in the blocked area. Consequently, the signal quality is affected, and a problem such as the signal attenuation of the beams is caused. In this case, the terminal instructs the base station to disable or delete the beams, to avoid affecting the quality of communication between the terminal and the base station.
[00237] For ease of description, in this modality of this request, an example in which a network device is a base station is used for description. For example, the base station can be a base station with a 4G or 5G communication function, but this modality of this request is not limited to that.
[00238] The solution of the first form of the previous design is described below using an example with reference to Figure 16. As shown in Figure 16, the solution includes the following steps.
[00239] Step 200: The base station sends beam configuration information to the terminal.
[00240] The beam configuration information is used to instruct the terminal to communicate with the base station using a beam 1 and a beam 2.
[00241] Step 201: The terminal measures the signal strength of each of a beam 1 and a beam 2.
[00242] The terminal measures separately the intensity of
Petition 870190072993, of 07/30/2019, p. 85/115
80/98 beam 1 and beam 2 signal, to determine if a communication quality requirement is met.
[00243] Step 202: The terminal determines whether the signal strength of each of beam 1 and beam 2 is less than a threshold.
[00244] If the signal strength of beam 1 is less than the threshold and the signal strength of beam 2 is not less than the threshold, the terminal may determine that the signal quality of beam 1 is poorer, and if the terminal continues to communicate with the base station using beam 1, normal communication between the terminal and the base station can be affected.
[00245] Step 203: The terminal sends indication information to the base station using beam 1 or beam 2.
[00246] The indication information is used to instruct the base station to exclude or disable beam 1, and the indication information can be indication of deactivation information or indication of exclusion information. In addition, the indication information may include beam 1 identifier information, or beam 1 signal strength, or a CQI = 0.
[00247] The terminal can send first indication information to the base station using a MAC layer or an RRC layer. The first indication information can include indication of deactivation information or indication of exclusion information. The deactivation indication information or the exclusion indication information is used to instruct the base station to deactivate or exclude beam 1. The first indication information may further include a beam 1 CQI. For example, CQI = 0 is used by the terminal to indicate to the base station that the quality
Petition 870190072993, of 07/30/2019, p. 86/115
81/98 signal from beam 1 is no longer suitable for continuing to transmit data, so the base station disables or excludes beam 1. Optionally, the first indication information can include at least one of a beam 1 identifier, a beam 1 antenna port identifier, a beam reference signal 1 or other identifying information. Thus, upon receiving the first indication information sent by the terminal, the base station deactivates or excludes beam 1 using the deactivation indication information or the exclusion indication information in the first indication information, or the deactivation indication information or the exclusion indication information and the beam 1 identifier information included in the first indication information, to avoid affecting normal communication between the terminal and the base station when the data is still transmitted using beam 1 with poor signal quality .
[00248] Step 204: The base station disables or excludes beam 1.
[00249] After receiving the first indication information sent by the terminal, the base station disables or excludes beam 1. During communication with the base station, the terminal disables or excludes the beam that does not satisfy the communication quality requirement, so that if beam signals for communication between the terminal and the base station suddenly attenuate, a problem of wasted network resources caused when communication is still carried out using the beams can be avoided, and a problem of a large increase energy consumption caused when the terminal still communicates using the
Petition 870190072993, of 07/30/2019, p. 87/115
82/98 beams with relatively low communication quality can be avoided.
[00250] Step 205: The base station sends feedback information from the first indication information to the terminal.
[00251] The feedback information is used to instruct the terminal to stop monitoring beam 1. Because the base station stops communicating with the terminal using beam 1, a problem such as a waste of resources that is caused because the terminal continues to monitor beam 1 is avoided. The return information can carry the beam identifier information 1, and the beam identifier information 1 includes at least one of the beam identifier 1, the antenna port identifier of the beam 1, the beam reference signal 1, or other identifying information.
[00252] Step 206: The terminal stops monitoring beam 1.
[00253] After receiving the return information from the first indication information that is sent by the base station, the terminal can stop monitoring beam 1.
[00254] After the terminal sends the first indication information to the base station, the base station can disable or exclude beam 1 that does not meet the communication quality requirement, to be more specific, the base station can stop communicating with the terminal using beam 1. After sending the first indication information to the base station, the terminal can stop monitoring beam 1. Furthermore, after receiving the return information from the first indication information that is sent by the base station , the terminal may stop monitoring beam 1. Thus, if the base station is subject to external interference, or
Petition 870190072993, of 07/30/2019, p. 88/115
83/98 similar, since the base station does not receive the first indication information sent by the terminal and continues to send data to the terminal using beam 1, a data loss problem that is caused because the terminal prematurely stops monitoring beam 1 can be avoided.
[00255] In a second way of design in a modality provided in that order, during the movement of the terminal, the communication quality of a disabled beam or a new beam can satisfy a communication quality requirement. To apply the beam that satisfies the communication requirement for communication between the terminal and the base station, to improve the quality of communication between the terminal and the base station, in another modality provided in that order, the terminal can activate or add the beam that satisfies the quality of communication.
[00256] In the design way, the terminal can obtain a measurement result of a beam. The terminal can obtain measurement results from one or more beams. The one or more beams are deactivated beams or beams not configured for the terminal. For example, the measurement result may include a result of measuring the beam signal quality or a result of measuring a loss of beam path.
[00257] For the terminal, an unconfigured beam means that the terminal does not store information related to the beam.
[00258] For a beam state, refer to the first way of the previous project and the details are not described here again.
Petition 870190072993, of 07/30/2019, p. 89/115
84/98 [00259] The terminal can learn, in a plurality of ways, from a beam whose measurement result needs to be obtained: The terminal can determine the beam based on the configuration information configured and sent by the base station, or the terminal can voluntarily perform blind detection on the beam. The terminal can obtain the measurement result in a variety of ways. Consult the related content in the first project way and the details will not be described here again.
[00260] After obtaining the measurement results of one or more beams, the terminal can determine whether the measurement result of each of the beams satisfies a second quality condition, to be specific, determine whether the beam meets the quality requirement of communication. The second quality condition is a condition used to determine whether a beam satisfies the communication quality requirement and a beam satisfying the second quality condition can be considered as a beam satisfying the communication quality requirement. For example, the second quality condition may be that the signal quality is greater than a threshold, or the signal quality is greater than a threshold within a period of time or an amount of times that the signal quality is greater than a predefined number of times. For another example, the second quality condition may be that a loss of beam path is less than a threshold, or that a loss of beam path is less than a threshold within a period of time, or a number of times that the loss of beam path is less than a threshold within a period of time is greater than a predefined number of times. The content of the
Petition 870190072993, of 07/30/2019, p. 90/115
The second quality condition can be formulated as required, and the content of the second quality condition is not limited in that order. The second quality condition can be sent by the base station to the terminal or can be specified in a communication standard. The second condition of quality can also be implicitly indicated. For example, if it is specified in a standard that the quality requirement is not satisfied if the signal strength is less than or equal to a threshold A, it can be considered that it implies that the second quality condition is that the signal strength is greater than limit A.
[00261] After determining one or more beams that satisfy the communication quality requirement, the terminal can send second indication information to the base station. The second indication information is used to instruct to activate or add one or more beams that satisfy the communication quality requirement. Optionally, the terminal can send the second indication information to the base station using a beam other than the target beam. Optionally, the terminal can send the second indication information to a network device (such as the base station) using a macro base station or a low frequency network. For example, the terminal can send the second indication information to the base station using a MAC layer or an RRC layer.
[00262] Optionally, before sending the second indication information to the base station, the terminal can actively activate or add one or more beams that satisfy the communication quality requirement, for
Petition 870190072993, of 07/30/2019, p. 91/115
86/98 possible data transmission.
[00263] The second quality condition can be sent by the base station to the terminal or can be specified in a communication standard.
[00264] Optionally, if a beam meets the communication quality requirement it can be determined by determining an amount of NACKs received on the beam. In other words, the first quality condition and the second quality condition can use a number of NACKs as a basis for determination. For example, the first quality condition may be that the number of NACKs is greater than a first threshold, and the second quality condition may be that the number of NACKs is less than a second threshold. The information identifying one or more beams that satisfy the communication quality requirement can be used as the second indication information or as part of the second indication information. The information that identifies one or more beams that satisfy the communication quality requirement can be identifiers of one or more beams that satisfy the communication quality requirement, antenna port identifiers corresponding to one or more beams that satisfy the quality requirement communication signals, reference signals corresponding to one or more beams that satisfy the communication quality or similar requirements. Optionally, the second indication information can also include activation indication information or addition indication information. The activation or addition indication information can be represented using a bit.
[00265] Optionally, after sending the second information
Petition 870190072993, of 07/30/2019, p. 92/115
87/98 indication to the base station, the terminal can monitor the one or more beams that satisfy the communication quality requirement, so that when the base station transmits data to the terminal using the one or more beams that satisfy the requirement communication quality, the terminal can obtain, over time, the data sent by the base station in one or more beams, satisfying the communication quality requirement. Optionally, after receiving feedback information from the second indication information that is sent by the base station, the terminal can start monitoring the one or more beams that satisfy the communication quality requirement. The feedback information can carry the activated or added beam identifier information, and the beam identifier information includes at least one of the beam identifier, a beam antenna port identifier, or a beam reference signal, or other identifying information. For example, the second indication information instructs to activate or add a beam 3 and a beam 4. The return information from the base station indicates that the beam 4 can be activated, and after receiving the return information, the terminal can monitor data communication in beam 4.
[00266] After the base station receives the second indication information sent by the terminal, the base station can activate or add, based on the second indication information, the one or more beams that satisfy the communication quality requirement, or the station base can activate or add, based on the second indication information, some of the one or more beams that satisfy the communication quality requirement. The base station can communicate
Petition 870190072993, of 07/30/2019, p. 93/115
88/98 with the terminal based on one or more beams activated or added that satisfy the communication quality requirement.
[00267] Optionally, the second indication information sent by the terminal to the base station can also include channel status information (CSI) of the one or more beams that satisfy the communication quality requirement, or other information that may reflect the quality of communication. After receiving the previous information, the base station can select a relatively good beam to perform an activation or addition operation.
[00268] It should be noted that the solution in which the terminal sends the second indication information to the base station can be combined with the solution in which the terminal sends the first indication information to the base station.
[00269] The first referral information or the second referral information is sent in a plurality of ways. For example, the first indication information or the second indication information is sent using MAC layer signaling or RRC layer signaling. For another example, the first indication information or the second indication information is sent using beam control signaling or beam management signaling.
[00270] In a variant of the solutions in the two previous design ways, the base station can obtain a beam measurement result, and send first indication information or second indication information to the terminal, to instruct the terminal to disable / delete, or activate / add the beam. For specific content, see the
Petition 870190072993, of 07/30/2019, p. 94/115
89/98 two previous design ways, and it is only necessary to replace the terminal in the previous two design ways with the base station, and replace the base station with the terminal, and the details are not described here again.
[00271] Optionally, in a scenario in which an uplink transmission link and a downlink transmission link for communication between the terminal and the base station have no symmetry (that is, non-respiratory), the terminal can implement the solutions in the previous two design ways for a downlink beam, and the base station can implement the solutions in the previous two design ways for an uplink beam.
[00272] For facility in description in this modality of that order, one example in what a device for network is a base station is used for description. Per example, the
base station can be a base station with a 4G or 5G communication function, but this modality of this request is not limited to that.
[00273] The solution in the second form of the previous project is described below using an example with reference to Figure 17. As shown in Figure 17, the solution includes the following steps.
[00274] Step 300: The base station sends beam configuration information to the terminal.
[00275] The beam configuration information is used to instruct the terminal to determine whether a beam 3 and a beam 4 satisfy a communication quality requirement.
[00276] Step 301: The terminal measures the signal strength of each of a beam 3 and a beam 4. The terminal can measure the signal strength of, for example, beam 3 and the beam
Petition 870190072993, of 07/30/2019, p. 95/115
90/98 for communication between the terminal and the base station, to obtain the signal strength of each of the beam 3 and the beam 4. 4.0 beam 3 and the beam 4 can be beams not configured by the base station for the terminal for use or are beams disabled for the terminal.
[00277] Step 302: The terminal determines whether the signal strength of each of beam 3 and beam 4 is greater than a threshold.
[00278] If the terminal determines that the signal strength of beam 3 is greater than the threshold, but the signal strength of beam 4 is less than the threshold, the terminal can determine that the signal strength of beam 3 can satisfy a communication requirement between the terminal and the base station.
[00279] Step 303: The terminal sends the second indication information to the base station.
[00280] The second indication information is used to instruct the base station to activate beam 3 or add beam 3 for communication with the terminal.
[00281] The terminal can send the second indication information to the network device using a beam other than beam 3. The second indication information can include a beam identifier 3, or includes an antenna port identifier to transmit the beam 3, or a beam 3 reference signal, or other information that can be used to identify the beam. Optionally, the second indication information can also include activation indication information or addition indication information. Thus, when receiving the second indication information sent by the terminal, the station
Petition 870190072993, of 07/30/2019, p. 96/115
91/98 base activates beam 3 or adds beam 3 to the terminal, to improve the quality of communication between the terminal and the network device. The addition of beam 3 to the terminal means that beam 3 is configured for the terminal for use.
[00282] Step 304: The base station activates or adds beam 3.
[00283] After receiving the second indication information sent by the terminal, the base station can activate or add beam 3 and, subsequently, the base station can communicate with the terminal using the beam. Because beam 3 has relatively good communication quality, the communication efficiency between the terminal and the base station is effectively improved.
[00284] Step 305: The base station sends return information from the second indication information to the terminal.
[00285] After the base station activates or adds beam 3, to allow the terminal to monitor beam 3 in time, the base station sends the return information from the second indication information to the terminal. The feedback information may contain beam identifier information 3, and beam identifier information 3 includes at least one of the beam identifier 3, the antenna port identifier of beam 3, the beam reference signal 3, or other identifier information.
[00286] Step 306: The terminal monitors beam 3.
[00287] After receiving the return information from the indication information that is sent by the base station, the terminal can monitor beam 3, to receive data that is sent by the base station using beam 3.
Petition 870190072993, of 07/30/2019, p. 97/115
92/98 [00288] Optionally, after sending the indication information to the base station, the terminal can voluntarily monitor the beam 3, without waiting for the return information of the indication information from the base station.
[00289] As shown in Figure 18, a modality of this request also provides a terminal, configured to implement the solution on one terminal side in the first way of the previous project. The terminal includes: a processor 11, a transmitter 12 and a receiver 13. Processor 11 is configured to obtain a beam measurement result. For a specific content to obtain the beam measurement result, consult the content in the first project way in the previous modality.
