    METHODS FOR OPERATING A NETWORK NODE AND USER EQUIPMENT, NETWORK NODE, USER EQUIPMENT, AND, MEDIA CARRIER ARRANGEMENT
    Technical Field [001] This description refers to wireless communication technology, in particular, in the context of 5G telecommunication, for example, New Radio (NR) or Evolution LTE.
    Fundamentals of the Invention [002] Following carrier aggregation, in which a plurality of carriers are aggregated or associated together in the frequency domain, the current development of wireless communication technology also goes in the direction of aggregating transmission timing structures in the time domain.
    Summary of the Invention [003] It is an objective of this description to provide approaches that allow efficient signaling in the context of slot aggregation as a form of aggregation of the transmission synchronism structure, in particular, signaling with limited overprocessing.
    [004] The approaches described here are particularly useful in the context of NR Radio Access Technology / Networks (NR RAT / RAN). Thus, a network node can, in particular, a gNB (or an eNB in some cases).
    [005] In this way, a method for operating a network node in a Radio Access Network is described. The method comprises transmitting a downlink control information message, the downlink control information message comprising a slot allocation indication and a symbol allocation indication. The slot allocation indication indicates a slot aggregation comprising
    Petition 870190110081, of 10/29/2019, p. 7/11
    2/38 a plurality of slots that are allocated for communication with at least one user device, where each slot comprises a plurality of symbols. The symbol allocation indication indicates the allocation of symbols on at least one channel according to an allocation pattern for two or more of the plurality of slots.
    [006] Also, a network node for a Radio Access Network is described. The network node is adapted to transmit a downlink control information message, a downlink control information message comprising a slot allocation indication and a symbol allocation indication. The slot allocation indication indicates a slot aggregation that comprises a plurality of slots that are allocated for communication with at least one user device, each slot comprising a plurality of symbols. The symbol allocation indication indicates the allocation of symbols on at least one channel according to an allocation pattern for two or more of the plurality of slots. The network node may comprise, and / or be adapted to use, a processing circuit system and / or a radio circuit system, in particular, a transmitter, for such transmission. Alternatively, or in addition, the network node may comprise a corresponding transmission module.
    [007] A method for operating user equipment, UE, on a Radio Access Network can be considered. The method comprises communicating using a slot aggregation based on a received downlink control information message, the downlink control information message comprising a slot allocation indication and a symbol allocation indication. The slot allocation indication indicates a slot aggregation that comprises a plurality of slots that are allocated for communication with the user equipment, where each slot comprises a plurality of
    Petition 870190108664, of 10/25/2019, p. 8/68
    3/38 symbols. The symbol allocation indication indicates the allocation of symbols on at least one channel according to an allocation pattern for two or more of the plurality of slots.
    [008] Furthermore, a user equipment for a Network of
    Radio access is described. The user equipment is adapted to communicate using a slot aggregation based on a received downlink control information message, the downlink control information message comprising a slot allocation indication and a symbol allocation indication. . The slot allocation indication indicates a slot aggregation that comprises a plurality of slots that are allocated for communication with the user equipment, where each slot comprises a plurality of symbols. The symbol allocation indication indicates the allocation of symbols on at least one channel according to an allocation pattern for two or more of the plurality of slots. The UE may comprise, and / or be adapted to use, a processing circuit system and / or a radio circuit system, in particular, a transmitter and / or a receiver and / or a receiver, for such communication. Alternatively, or in addition, the UE may comprise a corresponding communication module.
    [009] The slot allocation indication may comprise a bit pattern indicating the number of slots that are aggregated and / or a slot indicating the slot location, the slot indicating the slot location indicating the location of an aggregation reference slot of slot. There can be a unique mapping or 1-1 of the length of the slot aggregation (number of slots in the aggregation) and / or of the reference slot location with the bit pattern, for example, according to a table, which can be predefined or configured.
    [0010] A slot location can, in general, refer to an arrangement in the time domain and / or in relation to a timing or a structure of
    Petition 870190108664, of 10/25/2019, p. 9/68
    4/38 timing. A slot location can indicate where in time a slot is located, for example, by providing an absolute slot number or a slot number in relation to another slot, for example, a slot in which the downlink control information is received. The reference slot can be a slot aggregation slot, based on whose location the slot aggregation location can be determined or fixed. The reference slot can, in particular, be the first slot in the slot aggregation, or the last slot in the slot aggregation. Based on the reference slot and the number of slots in the slot aggregation, the time span covered by the slot aggregation can be defined or determined.
    [0011] A bit pattern can, in general, comprise one or more bits, in particular 2, 3 or 4 bits. In general, the symbol allocation indication can be considered to comprise 3 bits, which can be mapped to allocation patterns, for example, represented by the start symbol and / or the end symbol and / or by the length. The slot allocation indication can comprise 3 bits, which can be mapped to the locations of the reference slot and / or the number of slots in an aggregation.
    [0012] The symbol allocation indication may comprise a bit pattern, the bit pattern indicating the allocation pattern and / or the channel or channels in which the symbols are allocated.
    [0013] The pattern (allocation) can indicate or represent a start symbol and / or an end symbol and / or a number of symbols allocated to a specific channel.
    [0014] In some variants, the allocation pattern may indicate or include a security period between the symbols of the allocation pattern allocated on a downlink channel and the symbols of the pattern allocated on an uplink channel, and / or vice versa -version. A security period can comprise and / or extend across one or more symbol lengths. A security period can be associated
    Petition 870190108664, of 10/25/2019, p. 10/68
    5/38 to no transmission or reception to be scheduled.
    [0015] The downlink link control information message may comprise one or more deviation indications, a deviation indication, in general, indicating a deviation from the standard for one or more slots. Alternatively, or in addition, the downlink control information message may indicate the allocation of the frequency resource, for example, the subcarrier range, for one or more, in particular for all, slot aggregation slots. The allocation of the frequency resource can be indicated by a frequency allocation indication, and / or it can be the same for more than one, in particular for all, slot aggregation slots. In the latter case, only one indication may be necessary and / or provided. Alternatively, or additionally, the downlink control information message may comprise a frequency hopping indication, which may indicate a frequency hopping scheme for the channels allocated, for example, between different slots in the slot aggregation, and / or in individual slots.
    [0016] Alternatively, or additionally, the network node may be considered to be adapted to, and / or the method for operating the network node comprises, transmitting a second message, for example, a downlink control information message and / or another configuration message (message comprising the configuration data), the second message comprising one or more deviation indications. Communication using slot aggregation can also be based on the second message. In this way, greater flexibility for deviations from the standard can be provided, while limiting the overprocessing of the downlink control information message. The second message, and / or the downlink control message, can be valid for the duration of the slot aggregation (dynamic), or valid for a plurality of such durations (semi-static), for example,
    Petition 870190108664, of 10/25/2019, p. 11/68
    6/38 provided in the RRC signaling.
    [0017] The allocation of a slot aggregation for communication can refer to the allocation of resources associated with the aggregation slots for communication. The resources can be time frequency resources associated with, and / or arranged or located in, the time interval defined by the slot aggregations, respectively associated with the symbol time intervals of the slot aggregation symbols, which comprise the slot slot symbols. aggregation. The allocation can, in general, comprise indicating, for example, for a user equipment, which symbols and / or resources to use for which type of communication, for example, transmission or reception, and / or on which channel.
    [0018] An allocation pattern can, in general, indicate at least one channel that is allocated in one or more symbols (or vice versa, since the allocation can represent an exclusive mapping or 1-1). However, in some cases, more than one channel can be allocated by a symbol, for example, a control and a data channel. In this case, the channels can be multiplexed, in particular, on the frequency. Such channels can represent the same communication direction, for example, transmission or reception. The allocation pattern can indicate the frequency resource (s) allocated on the channel (s), or it can be implicitly indicated, for example, according to a configuration or preset or rule. An allocation pattern can allocate symbols to two or more slots, in such a way that the symbol pattern is repeated for each slot. For example, the same channel (s) can be allocated in symbols (respectively, the associated resources) with the same number inside each slot. It can be considered that the symbols in a slot can be numbered by successive integers, for example, from 0 to 6 or 0 to 13, or 1 to 7 or 1 to 14, depending on the total number of symbols in a slot. The numbering can be similar between the slots with the same number of symbols.
    Petition 870190108664, of 10/25/2019, p. 12/68
    7/38
    Successively numbered symbols can be neighbors to each other in the time domain, with a common time limit.
    [0019] The downlink control information message can allocate and / or schedule slot aggregation, in such a way that the resources of the slot aggregation are allocated for communication.
    [0020] A slot can comprise a plurality of symbols, in particular 7 or 14 symbols. However, a slot can be implemented as a mini-slot with fewer symbols than a full slot in some variants. It can be considered that the slot aggregation slots have the same number of symbols, and / or that the slot aggregation slots have the same durations (time domain extension). However, they can be considered variants in which different slot durations, or slots with different numbers of symbols, are aggregated in a slot aggregation. In this context, it can be considered that an allocation pattern only refers to slots with the same duration or the same number of symbols, in relation to the limited signaling overprocessing. A slot aggregation can comprise two or more slots, in particular 2, 3 or 4, or an even number of slots.
    [0021] The allocation of symbols on at least one channel may comprise indicating one or more channels on which it communicates. A channel can be an uplink or downlink or side link channel. In particular, a channel can be a physical channel. Examples of channels that can be allocated include PUCCH, PUSCH, PDSCH, PDCCH. A channel can be a control channel, for example, PUCCH or PDCCH, or a data channel, for example, PUSCH or PDSCH. A control channel, in particular a downlink control channel, can be arranged or allocated in a control region, which can cover one or more symbols of a slot in the slot aggregation, for example, at the beginning of the slot. It can be considered that in an uplink control region it is
    Petition 870190108664, of 10/25/2019, p. 13/68
    8/38 an uplink control channel is allocated. An allocation pattern can be, for example, continuous in the time domain and / or in the frequency domain for a time interval that covers one or more symbols and / or a frequency interval that covers one or more subcarriers. A pattern like this can appear rectangular in a representation of the time / frequency diagram. The symbol allocation indication can indicate the location and / or extent of a pattern like this in the time domain, for example, by indicating a start and end symbol, and / or a symbol and a duration (for example, number of symbols) or a start or end length (also referred to as a stop). A symbol can, in particular, be an OFDM symbol (Orthogonal Frequency Division Multiplexing), for example, in downlink NR, or an OFDMA symbol (Orthogonal Frequency Division Multiple Access) or SCFDMA (Frequency Division Multiple Access) with Individual Carrier) in ascending link or side link.
    [0022] Communication using a slot aggregation may comprise transmitting and / or receiving on the allocated channels according to the allocation pattern.
    [0023] The slots in a slot aggregation can be arranged in time in such a way that they form a continuous time slot covered by the slot times of the slot symbols.
    [0024] In general, a symbol can be associated with a symbol time interval, and a frequency range, for example, a subcarrier number. For ease of reference, this can be referred to a symbol even if only the extension of the time domain (symbol time interval) is referred to. In the context of resources or allocation, an extension of a symbol in the frequency domain can be considered. The symbols or slots in a slot aggregation can comprise the same extension in the frequency domain, for example, which refers to the same
    Petition 870190108664, of 10/25/2019, p. 14/68
    9/38 subcarriers or carriers. The extension in the frequency domain can be continuous.
    [0025] An allocation pattern that refers to a plurality of slots can be considered to comprise a valid (sub) allocation pattern for one slot, which is repeated in the other slots of the plurality of slots.
    [0026] It should be noted that, in some variants, the slot allocation indication and the symbol allocation indication refer to the allocation in the time domain, referring to the symbols or slots, respectively, their associated time intervals . The frequency allocation can be implicitly indicated, or explicitly, with a corresponding indication of frequency allocation in the downlink control information message.
    [0027] A downlink control information message may comprise downlink control information, in particular referring to scheduling and / or allocation, for uplink and / or downlink communication and / or in side link.
    [0028] A program product that comprises the instructions that cause a processing circuit system to control and / or perform any of the methods described here is also described.
    [0029] Furthermore, a carrier media arrangement is described that carries and / or stores a program product as described here.
    [0030] A transmission timing structure can, in general, comprise a number (for example, predefined and / or configured) of symbols or symbol time intervals. A slot can be considered a representation or an implementation of a transmission timing structure, and the terms can be interchanged in the context of this description. A transmission timing structure can define a time interval. With a frame and / or a synchronism slot from
    Petition 870190108664, of 10/25/2019, p. 15/68
    10/38 transmission can be associated with frequency resources, in such a way that a slot can represent time / frequency resources, based on a slot time interval. A slot aggregation can comprise a plurality of scheduled slots with a single downlink control information message.

    Detailed Description [0032] The NR supports a very flexible frame structure. A slot can be 7 or 14 OFDM symbols long. In TDD, a slot range can contain transmissions both in DL (Downlink) only, in UL (Upward Link) only, and in UL and DL. Figure 1 graphically shows a slot in DL only, figure 2 a slot in UL only, figure 3 a heavy slot in DL with UL at the end, and figure 4 a heavy slot in UL with DL at the beginning. Figures 1 to 4 show four types of TDD slots. In these examples, the slot length is N_slot = 14. It should be noted that the concepts and approaches described here are only illustrated in the context of TDD, but are also applicable in Frequency Division Duplex (FDD). Furthermore, the duration of the slot can vary depending on the frequency or numerology used, since the spacing of the subcarrier may depend on both, in such a way that the time interval of the symbol associated with a symbol can be different for different frequencies and / or carrier numerologies. Thus, for an equal number of symbols in a slot, the duration of the slot can vary. It can be considered that the slots described here refer to the same numerology and / or spacing as the subcarrier and / or carrier, in such a way that the symbols can have the same time interval as the symbol (symbol duration).
    [0033] The DL parts of a slot often start with a DL control region. The presence of a DL control region and the length of the DL control region can be dynamically indicated (for example, by means of DCI in the PDCCH), semi-statically configured (for example, by means of RRC signaling) or blindly detected by the UE.
    [0034] The DL data region (PDSCH) in a slot can extend from the beginning of the slot to the end of the slot (DL only slots) or stop earlier
    Petition 870190108664, of 10/25/2019, p. 17/68
    12/38 to accommodate an UL opportunity in the end. The start of the PDSCH can be as much the beginning of the slot as it can start in or after the control region. In the event that the PDSCH starts in the control region, special care is needed on how to multiplex the data and control channels (PDCCH) in the control channel region. If an UL opportunity exists at the end of the slot interval, the PDSCH must stop early to accommodate the UL transmission together with DL-> UL and possibly UL-> DL safety times or periods, for example, during switching back to DL in the next slot.
    [0035] Similar to the heavy slots in DL, they are the heavy slots in UL, but, for this, the DL region (also referred to as DL by conciseness) is very short (for example, 1 or 2 symbols), followed by a safety time and a UL region (also referred to as UL). A DL region can comprise one or more symbols in which downlink transmission (or reception from the UE point of view) is scheduled, a UL region can comprise one or more symbols in which the transmission in uplink is scheduled. Similarly, side link regions can be considered, for example, side link transmission regions and / or side link reception regions.
    [0036] The UL contains at the beginning the UL data region (PUSCH) and, optionally, a UL control region at the end (PUCCH). PUSCH can stop before the UL control region or it can continue until the end of the slot range. In the event that the PUSCH continues to the end of the slot and superimposes a symbol that contains the PUCCH, special care is needed on how to multiplex the data and control channels (PUCCH) in the control channel region.
    [0037] Slot aggregation is discussed below.
    [0038] To enable longer transmissions (to improve coverage), or to use less PDCCH transmissions (to reduce the
    Petition 870190108664, of 10/25/2019, p. 18/68
    13/38 overprocessing of the control channel), it is possible to schedule transmission units that consist of several slots. Such a unit is referred to as slot aggregation. One possibility would be to schedule PDSCH / PUSCH for each slot with its own PDCCH, however, in this case, the distinction for individual scheduling of multiple slots is uncertain. Therefore, it is considered that an aggregated slot is scheduled with a single DCI (a single message). DCI, Downlink Control Information, can be considered to represent the most widespread downlink control information in the context of NR.
    [0039] Figures 5 to 7 show examples of different slots aggregated in DL. As you can see, the symbols available for the PDSCH, as well as the symbol pattern, depend heavily on the format of the slot aggregation. These examples show that the PDSCH does not overlap the DL control region, however, it is also possible for the PDSCH to overlap (partially or completely in time) with the DL control region. Specifically, figures 5 to 7 show examples of slot aggregation. In these examples, the slot length is N_slot = 14. In figure 5, a DL slot is followed by a DL slot with no DL control region. In figure 6, both aggregate slots have a DL control region. In figure 7, a DL slot with the control region is followed by a mixed slot with both the DL control region and the UL opportunity.
    [0040] In figures 8 to 10, the examples for the slot aggregation in UL are shown. As you can see, the symbols available for PUSCH, as well as the symbol pattern, depend a lot on the format of the slot aggregation. Figures 8 to 10, in particular, show examples of UL slot aggregation. In these examples, the slot length is N_slot =
    14. In figure 8, a UL heavy slot is followed by an UL slot only. In figure 9, both slots are UL-weighted. In Figure 10, both slots are UL heavy and have an UL control region at the end.
    Petition 870190108664, of 10/25/2019, p. 19/68
    14/38 [0041] As can be seen from figures 5 to 7 and figures 8 to 10, a wide variety of formats of the slot aggregation can be considered. The symbols available for the PDSCH / PUSCH depend largely on the format of the slot aggregation. Since an aggregate slot is signaled with a single DCI message, the resource allocation in particular in the time domain, in relation to the allocation of symbols in channels, for the complete aggregate slot, is contained in a single DCI message. Given the large number of possibilities (of which figures 5 to 10 show only a few examples), the signaling for resource allocation in the PDSCH / PUSCH time domain can become very complex and require a large signaling overprocessing.
    [0042] Approaches to reduce overprocessing for signaling resource allocation in the time domain in slot aggregation are discussed. It is proposed that the signaling allows the definition with details of the allocation in the PDSCH / PUSCH time domain in a single slot based on a symbol allocation indication (hereinafter referred to as symbol allocation). At least one of flexible start position, length, and flexible stop position can be provided. For slot aggregation, symbol allocation is applied to multiple slots. In addition, the number of scheduled slots can also be signaled using a slot allocation indication (hereinafter referred to as slot allocation).
    [0043] The required signaling for slot aggregation is only slightly higher than for a single slot (scheduled slot numbers need to be provided), which, however, will only require very few bits.
    [0044] An optional extension of the approaches allows adjustments (deviations) in the repeated resource allocation, for example, each (or at least some) scheduled slot may have a single additional bit or very few additional bits assigned to signal any adjustment, for example example, in the form of
    Petition 870190108664, of 10/25/2019, p. 20/68
    15/38 an indication of deviation.
    [0045] The proposed solution reduces signaling overprocessing for resource allocation in the time domain in slot aggregation. This reduces the size of the DCI, which reduces the load on the control channel, often a bottleneck in wireless systems. With a reduced overprocessing of the control channel, it is more often possible to schedule the terminals avoiding the situation where data resources are available, but cannot be scheduled due to the lack of control resources. In addition, the reduced size of the DCI also results in better control signal coverage and / or better control signal detection rate.
    [0046] The field of resource allocation in the time domain of a DCI message for slot aggregation may comprise two parts (for example, two fields or a joint field from both of which the information can be derived, and / or two-bit patterns, or one-bit pattern associated from two-bit patterns to a larger bit pattern), the two parts representing a symbol allocation indication and a slot allocation indication. The number of slots scheduled (hereinafter referred to as slot allocation) can be indicated, and details of resource allocation in the PDSCH / PUSCH time domain in a slot (hereinafter referred to as symbol allocation) can be indicated, the that represents an allocation pattern. The symbol allocation specified in 2) is applied to all or at least multiple scheduled slots in the slot aggregation.
    [0047] Figure 11 shows an example for slot aggregation in DL. The resource allocation field in the time domain specifies that 2 slots are aggregated, and that the PDSCH starts at symbol 1 and ends at symbol 11.0 The same pattern as the PDSCH start and end symbols is applied to both slots. Using Table 1 and Table 2 examples to indicate slot allocation and symbol allocation, the example in figure 11 will use the
    Petition 870190108664, of 10/25/2019, p. 21/68
    16/38 entries 001 or 101 for slot allocation (Table 1, to indicate 2 aggregate slots, 001 or 101 for different first slot values) and 011 for symbol allocation (Table 2, N_slot = 14 considered). As can be seen, figure 11 shows the slot aggregation in DL with 2 slots. Each slot uses the same resource allocation in the time domain. In this example, the slot length is N_slot = 14.
    [0048] The aggregation of UL slot is shown in figure 12, in which, also, two slots are aggregated. The symbol allocation specifies that symbols 3 through 13 are used in each slot for the PUSCH. Using Table 1 and Table 3 examples to indicate slot allocation and symbol allocation, the example in figure 12 will use entries 001 or 101 for slot allocation (Table 1, to indicate 2 aggregate slots, 001 or 101 for the first different slot values) and 101 (Table 3, N_slot = 14 considered) for the symbol allocation. For UL slot aggregation with 2 slots in figure 12, each slot uses the same resource allocation in the time domain (allocation pattern). In this example, the slot length is N_slot = 14.
    [0049] Slot allocation is discussed in more detail below.
    [0050] The field that indicates how many slots are scheduled can also indicate which slots, at least in combination with some other information, for example, a semi-statically configured slot shift. For DL, the PDSCH will often start in the same slot in which the DCI message is received, in this case, a simple indicator of the length of the slot would be sufficient. In UL, however, only fast terminals will be able to receive an UL grant (PDCCH) in a DCI message in slot n, and to transmit PUSCH in slot η. Most terminals will only support transmission in slot n + 1. One possibility would be to semi-statically set a value of displacement k, indicating a location in the reference slot, so that PUSCH always starts in slot n + k since DCI was received in slot η. Table 1 shows a table in which the allocation of
    Petition 870190108664, of 10/25/2019, p. 22/68
    17/38 slot contains 3 bits. The first bit indicates that the assignment starts in slot n + n_ (OS, l) or n + n_ (0S, 2), with n_ (OS, l) and n_ (OS, 2) displacement values semi-statically configured, which can , for example, be 0 and 1 (typical values for DL), or 1 and 2 (typical values for UL). The n is the slot in which the DCI was received. Thus, the location of the first slot (start slot) as the reference slot is indicated. The remaining two bits indicate the number of aggregated slots, in this example, they indicate 1 to 4 aggregated slots, but, in a more general case, these four values may be different, for example, semi-statically configured.
    [0051] Table 1 The exemplary slot allocation consists of 3 bits. The first bit indicates the first slot and the remaining two bits the number of aggregated slots. _________________________________________
    Bit pattern First slot Number of slot (s) aggregated 000 n + n_ (OS, l) 1 001 n + n_ (OS, l) 2 010 n + n_ (OS, l) 3 011 n + n_ (OS, l) 4 100 n + n_ (OS, 2) 1 101 n + n_ (OS, 2) 2 110 n + n_ (OS, 2) 3 111 n + n_ (OS, 2) 4
    [0052] If a fixed initial position (semi-statically configured) of the data channel (PDSCH and PUSCH) is very restrictive, a start / stop allocation similar to the LTE format 2 resource allocation can be considered for slot allocation. If non-contiguous slot aggregation is supported, a bitmap is required with a bit position for each slot that can be scheduled, for example, [bO bl b2 b3] can refer to slots n + k + bi with n being the slot in which the DCI was received, and k being a fixed or semi-statically displaced number.
    [0053] Symbol allocation is discussed in more detail below.
    [0054] Table 2 shows an example of how DL symbols are allocated in PDSCH. Depending on the presence and shape of a control channel region, a PDSCH start position of 0 and 1 may imply that
    Petition 870190108664, of 10/25/2019, p. 23/68
    18/38 the PDS CH shares an OFDM symbol with the PDCCH (considering a control channel region that varies from 0 to 2 OFDM symbols). The PDSCH can extend either to the end of the slot (at the UL opportunity at the end of the slot range), or to the symbols N_slot-4 or N_slot-3. For the last two cases, a UL opportunity of 2 and 1 symbols together with a safety time of 1 symbol was considered. N_slot is the length of the slot and can, for example, have 7 or 14 symbols. To keep the number of bits at 3, the combination of the start position 0 and the end position N_slot-4 has been omitted. In Table 2, the start and stop positions are provided, start (or stop) and length indications will be an alternative signal.
    Table 2 Symbol allocation for the PDSCH______________
    Bit pattern PDSCH start symbol Stop symbolPDSCH 000 0 N_slot-3 001 0 N_slot-1 010 1 N_slot-4 011 1 N_slot-3 100 1 N_slot-1 101 2 N_slot-4 110 2 N_slot-3 111 2 N_slot-1
    [0055] Table 3 shows a similar table for the allocation of the PUSCH symbol. The PUSCH can start either at symbol 1 (in the DL and in the DL control region in this slot, that is, the PUSCH is scheduled from a previous slot, but 1 empty symbol at the beginning is required for the switching time and the advance synchronization), as well as in symbols 2, 3, and 4. The last three cases consider a DL control region of 1 or 2 symbols together with a safety time of 1 or 2 symbols. A longer security period can, for example, be provided if the DCI indicates the PUSCH in the same slot, and that the UE needs more processing time, while a security period of 1 symbol would be sufficient if the PUSCH was sent in the next slot or subframe. If PUSCH is transmitted in the next slot or subframe, security
    Petition 870190108664, of 10/25/2019, p. 24/68
    19/38 would only need to cover the switching time and the timing of the UE. The PUSCH can either extend to the end of the slot or stop earlier (in this example, 1 symbol earlier to make room for a short PUCCH at the end, it can also be 2 symbols or maybe even 1 or 2 symbols at the expense of one additional signaling bit). It would also be possible to combine slot allocation (Section 5.1.1) and symbol allocation, since, for example, the combination of the PUSCH that starts in a future slot, together with the PUSCH that starts at symbol 4, may not be required (PUSCH start symbol 4 will give an UE extra time to decode the DCI if the DCI is sent in the same slot). In Table 3, the start and stop positions are provided, start (or stop) and length indications will be an alternative signal.
    Table 3 Symbol allocation for PUSCH______________
    Bit pattern Start symbolPUSCH PUSCH stop symbol 000 1 N_slot-2 001 1 N_slot-1 010 2 N_slot-2 011 2 N_slot-1 100 3 N_slot-2 101 3 N_slot-1 110 4 N_slot-2 111 4 N_slot-1
    Extensions [0056] The application of the same symbol allocation in all slots is, perhaps, very restrictive. For example, an aggregated PDSCH in a DL slot that is scheduled in slot n and starts in slot n at symbol 1 would have a hole at the beginning of all subsequent slots. In order to increase flexibility, small signal fields for some / all slots to indicate adjustments by the representation of the deviation indications can be provided in the downlink control information message. However, adjustment signaling (deviation indication (s)) can be limited to limit signaling overprocessing.
    [0057] Figures 13 and 14 show the examples in which 4 slots are
    Petition 870190108664, of 10/25/2019, p. 25/68
    20/38 scheduled in an aggregate. In figure 13 without allowed adjustments, the PDSCH would be mapped to symbols 1 to N_slot-1 in each slot, that is, there is a hole in the PDSCH in each slot. Allowing an adjustment for the first slot, it is possible to signal for all PDSCH symbol allocation from slots 0 to N_slot-1 (entry 001 in Table 2), but then signal an exception / adjustment for the first slot (PDSCH in the first slot starts at symbol 1), as shown in figure 14. In this example, N_slot = 7 is considered.
    [0058] It should be noted that the exceptions / adjustments mentioned can be considered deviations from the allocation pattern for specific slots.
    [0059] In particular, in figure 13, all slots use symbol allocation 1 to 6 (100 in Table 2) for PDSCH, and holes in the PDSCH mapping occur. In figure 14, using the corresponding deviation indication, all slots use the symbol allocation 0 to 6 (001 in Table 2) for the PDSCH and the holes in the PDSCH mapping can be avoided. The adjustment signal (deviation indication) is used for the first slot.
    [0060] Instead of explicitly signaling the setting for the first slot, an implicit rule can be applied instead. An example of a rule would be that the symbol start / stop allocation is valid in all slots in the aggregate slot, except the first slot, where the PDCCH symbol (s) that contained the DCI should be excluded. (s) of the start / stop allocation. Alternatively, if the PDSCH start position / PDCCH stop position / control region stop position is indicated in the group's common PDCCH, this information can be used to adjust the PDSCH start position in one or multiple slots in the aggregate slot (if PDCCH or the stop position of the control region is signaled, PDSCH is assumed to start after the PDCCH or the control region).
    [0061] A similar technique can be used to signal a PDSCH that stops early in the last slot to provide an UL opportunity. In this case, the common symbol allocation will signal that the PDSCH extends to
    Petition 870190108664, of 10/25/2019, p. 26/68
    21/38 the last symbol in each slot and the adjustment signal for the last slot will indicate that the PDSCH has stopped, for example, at the N_slot-2 symbol. Alternatively, if the DL stop position / UL start position is indicated on the group's common PDCCH, this information can be used to adjust the PDSCH stop position in one or multiple slots in the aggregate slot.
    [0062] The adjustment signal can also be used for PUSCH. For example, an aggregated PUSCH slot whose scheduling DCI is at the beginning of the first slot cannot start at symbol 0 in the first slot. Copying the same symbol allocation will again result in holes in the PUSCH mapping. Again, the common symbol allocation can signal that the PUSCH is mapped to symbols 0 through N_slot-1 in all slots, and the adjustment signal is used to modify the resource allocation in the time domain for the first slot.
    [0063] Another possibility is to repeat the symbol allocation only for a subset of the allocated slots. Symbol allocation to other slots, then, needs to be provided by other means.
    [0064] For even more flexibility, the symbol allocation can be provided for each of the slots allocated in the same DCI. This results in more signaling overprocessing, but since other parts of the DCI, such as resource allocation in the frequency domain, are not provided for each of the slots in the aggregate slot, the signaling is less than providing the separate DCI in each slot. In this way, the allocation pattern can specifically cover more than one slot with different or the same sub-patterns.
    [0065] In the DCI message, it can be additionally considered that, in one example, the same frequency allocation is used in all allocated slots. This, since, then, it would be possible to have a frequency allocation bit field in the DCI message for all aggregated slots.
    [0066] To introduce some frequency diversity, it may be possible to add a frequency hopping scheme at the top that is applicable
    Petition 870190108664, of 10/25/2019, p. 27/68
    22/38 per slot (potentially even intraslot). The resources in the frequency domain can be provided separately for each slot (or subset of slots in the aggregate slot) or a rule can be used to derive the resources in the frequency domain for at least one additional slot given the resources in the frequency domain for at least one slot. The [0067] In general, it can be considered to provide a downlink control information message that specifies the resource allocation in the time domain for such slot aggregation based on an allocation pattern for a single slot, which is applied in others, in particular all, scheduled slots in the aggregate slot. This reduces the overprocessing required for signaling the resource allocation in the time domain in the slot aggregation.

It can be considered that a channel (or side link communication structure refers to and / or uses one or more carrier (s) and / or frequency range (s) associated with, and / or being used by, cellular communication, by example, according to a specific license and / or standard Participants can share a channel and / or (physical) resources, in particular, in the frequency space and / or related to a frequency resource (such as a carrier) a side link, in such a way that two or more participants transmit on it, for example simultaneously, and / or shifted in time, and / or specific channels and / or resources can be associated with specific participants, so that, for example, only one participant broadcasts on a specific channel or on a specific resource or specific resources , for example, in the frequency space and / or related to one or more carriers or subcarriers.
    Petition 870190108664, of 10/25/2019, p. 40/68
    35/38 [00103] A side link can conform to, and / or be implemented in accordance with, a specific standard, for example, a standard based on LTE and / or NR. A side link can use TDD technology (time division duplex) and / or FDD (frequency division duplex), for example, configured by a network node, and / or preconfigured and / or negotiated between the participants. User equipment can be considered adapted for side link communication if it, and / or its radio circuit system and / or processing circuit system, is adapted to use a side link, for example, in one or more frequency bands and / or carriers and / or in one or more formats, in particular, according to a specific standard. In general, it can be considered that a radio access network is defined by two participants in a side link communication. Alternatively, or in addition, a radio access network can be represented, and / or defined with, and / or be related to a network node and / or in communication with a node like this.
    [00104] Communication or communicating can, in general, include transmitting and / or receiving signaling. Signaling can be associated with a specific channel. Communication on a side link (or side link signaling) can comprise using the side link for communication (respectively, for signaling). Transmission and / or transmitting on a side link on a side link can be considered by understanding the transmission using the side link, for example, associated resources and / or transmission formats and / or the circuit system and / or the air interface . Reception and / or reception on a side link on a side link can be considered by understanding reception using the side link, for example, the associated resources and / or the transmission formats and / or the circuit system and / or the air interface. Control information on the side link (for example, SCI) can, in general, be considered by
    Petition 870190108664, of 10/25/2019, p. 41/68
    36/38 understand the control information transmitted using a side link. Recognition signaling, as well as signaling an indication of the recognition position, can be considered examples of SCI, although in different directions of communication between the participants. In particular, the acknowledgment signal can be considered as in response to another control signal (for example, configuration control signal) and thus be referred to as response control signal. The configuration control signaling, in general, can configure a UE, for example, calendar resources and / or a union of resources. The signaling of an acknowledgment position indication can be considered an example of the configuration control signaling.
    [00105] A transmission synchronism structure can have a duration (length in time) determined based on the durations of its symbols, possibly, in addition to the cyclic prefix (s) used. The symbols of a transmission timing structure may have the same duration, or may, in some variants, have a different duration. A slot can be considered an example of a transmission timing structure, and the term slot can be considered interchangeable with the term transmission timing structure in the context of this description. A transmission timing frame or slot may comprise a predetermined number of symbols, for example, 7 or 14. A mini-slot may comprise a number of symbols less than the number of symbols in a slot. A transmission timing structure can cover a time span of a specific length, which can be dependent on the time duration of the symbol and / or the cyclic prefix used. A transmission timing structure can refer to and / or cover a specific time slot in a continuous time stream, for example, synchronized for communication. It should be noted that a subframe can be
    Petition 870190108664, of 10/25/2019, p. 42/68
    37/38 considered an example of a slot or a transmission timing structure with a fixed duration of 1 ms.
    [00106] In this description, for the purpose of explanation and not of limitation, specific details are presented (such as network functions, process steps and signaling in particular) in order to provide a careful understanding of the technique presented here. It will be apparent to those skilled in the art that the present concepts and aspects can be practiced in other variants and variants that escape these specific details.
    [00107] For example, the concepts and variants are partially described in the context of long-term evolution (LTE) or LTE-Advanced (LTE-A) or Next Radio technologies; however, this does not rule out the use of the present concepts and aspects in connection with additional or alternative mobile communication technologies, such as the Global System for Mobile Communications (GSM). Although the following variants are partially described in relation to certain Technical Specifications (TSs) of the Third Generation Partnership Project (3GPP), it will be realized that the present concepts and aspects can also be realized in connection with different Performance Management (PM) specifications ).
    [00108] Furthermore, those skilled in the art realize that the services, functions and steps explained here can be implemented using software that works in conjunction with a programmed microprocessor, or using an application specific integrated circuit (ASIC), a digital signal processor (DSP), a field programmable port arrangement (FPGA) or a general purpose computer. It will also be noticed that, although the variants described here are elucidated in the context of methods and devices, the concepts and aspects presented here can also be incorporated in a program product, as well as in a
    Petition 870190108664, of 10/25/2019, p. 43/68
    38/38 system comprising the control circuit system, for example, a computer processor and a memory coupled to the processor, in which the memory is encoded with one or more programs or program products that perform the services, functions and the steps described here.
    [00109] It is believed that the advantages of the aspects and variants presented here will be fully understood from the description described, and it will be apparent that several changes can be made in the form, in the constructions and in the arrangement of the exemplary aspects of it without escaping the scope of the concepts and aspects described here or without sacrificing any of their beneficial effects. The aspects presented here can be varied in many ways.
