Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to multi-beam transmission methods and apparatus. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) introduced Beam Failure Recovery (BFR) for Special Cells (SpCells) in Release 15 and BFR for Secondary Cells (SCells) in Release 16. BFR prevents triggering Radio Link Failure (RLF) at higher layers. The 3GPP RAN (Radio Access Network) #80 meeting decided to launch the "Further enhancements on MIMO (Multiple Input Multiple Output) for NR (New Radio)" work project (Work Iterm, WI), which enhances the BFR mechanism for multi-TRP (Multiple Transmitter and Receiver Point). Summary of the Invention

[0003] The BFR MAC CE in Release 16 includes a bitmap to indicate the cell (Ci domain) where beam failure has occurred. For each SCell experiencing beam failure, it may also include a byte to indicate beam failure information. This byte includes an AC (availability indication) field, which indicates whether a candidate RS ID field exists. If the candidate RS ID field exists, it is used to indicate a candidate RS ID; if it does not exist, the corresponding bits are reserved. Because Release 17 (R17) enhances the BFR mechanism for multi-TRPs, each TRP independently performs beam failure detection and recovery. Each TRP is configured with a set of reference signal resources for beam failure detection and a corresponding set of candidate reference signal resources. This necessitates enhancement of the MAC (Medium Access Control) CE (Control Element) used for BFR, and also requires enhancement of the BFR information reporting mechanism.

[0004] To address the aforementioned issues, this application provides a solution. The problem description uses a UU interface scenario as an example; this application is also applicable to scenarios such as sidelinks, achieving similar technical effects. Furthermore, using a unified solution across different scenarios helps reduce hardware complexity and cost.

[0024] As an example, the advantages of the above method include: when the size of the resources granted by the first uplink cannot accommodate all the BFR information, partial BFR information is sent first.

[0494] As a sub-implementation of this embodiment, the candidate RS resource belongs to a first type of candidate RS resource group that is associated with the RS resource subgroup corresponding to the BFR information.

[0495] As a sub-implementation of this embodiment, the first MAC domain is the AC domain, and the second MAC domain is the Candidate RS ID domain.

[0535] Example 3

[0536] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for control plane 300 is illustrated using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted packets and cross-area mobility support. The RLC sublayer 303 provides segmentation and reassembly of upper-layer packets, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and using RRC signaling to configure the lower layers. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). In the user plane 350, the radio protocol architecture for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355 is largely the same as the corresponding layers and sublayers in the control plane 300. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for the mapping between QoS streams and data radio bearers (DRBs) to support service diversity.

[0546] Example 4

[0547] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in the access network.

[0548] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0549] The second communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0550] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0551] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0552] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0553] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0581] In Example 5, at least one RS resource subgroup in each RS resource group of the first RS resource set has a BFR; whether the target MAC CE includes a second octet bitmap is related to the number of RS resource subgroups in the first RS resource set that have a BFR and whose associated cells are one of the K1 cells; if the target MAC CE includes the first bitmap subset and the second octet bitmap, the second octet bitmap includes an octet bitmap and is associated with K2 cells in the first cell group, the target MAC CE includes at least one BFR information between the first bitmap subset and the second octet bitmap; the cell identifier of any cell in the K1 cells is different from the cell identifier of any cell in the K2 cells; K1 and K2 are both positive integers; the sum of K1 and K2 is not greater than the total number of cells in the first cell group.

[0596] As an example, steps S5102 and S5103 are performed on the RS resource subgroup in SpCell.

[0597] Example 6

[0598] Example 6 illustrates a schematic diagram of how to determine whether a target MAC CE includes a second octet bitmap according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown.

[0599] In Example 6, whether the target MAC CE includes the second octet bitmap is related to whether there is at least one RS resource subgroup in the first RS resource set that has a BFR and is associated with a cell other than the K1 cells.

[0600] As an example, if the first RS resource set contains at least one RS resource subgroup with a BFR and whose associated cell is an RS resource subgroup of a cell other than the K1 cells, the target MAC CE includes the second octet bitmap; if the first RS resource set does not contain an RS resource subgroup with a BFR and whose associated cell is an RS resource subgroup of a cell other than the K1 cells, the target MAC CE does not include the second octet bitmap.

[0601] As an example, if there is at least one RS resource subgroup in the first RS resource set that has a BFR and is associated with a cell other than the K1 cells, and provided that the size of the resource granted by the first uplink grant is not exceeded, the target MAC CE can accommodate the first bitmap subset, the BFR information of the first bitmap subset, and the second octet bitmap, wherein the target MAC CE includes the second octet bitmap.

[0602] As an example, if the first RS resource set contains at least one RS resource subgroup of a cell that has a BFR and is associated with a cell other than the K1 cells, and the target MAC CE cannot simultaneously accommodate the first bitmap subset, the BFR information of the first bitmap subset, and the second octet bitmap, the target MAC CE does not include the second octet bitmap.

[0603] As an example, if there is no RS resource subgroup in the first RS resource set that has a BFR and whose associated cell is a cell other than the K1 cells, the target MAC CE does not include the second octet bitmap.

[0604] Example 7

[0605] Example 7 illustrates a schematic diagram of determining K1 cells and K2 cells according to a first criterion in one embodiment of this application.

[0606] In Example 7, the K1 cells are the first K1 cells in the first cell group sorted according to a first criterion, and the K2 cells are the K2 cells in the first cell group after the first K1 cells sorted according to the first criterion, wherein the first criterion includes sorting according to at least the cell identifier.

[0607] As an example, the phrase "sorted by cell identifier" means: sorted in ascending order by cell identifier.

[0608] As an example, the phrase "sorted by cell identifier" means: sorted in descending order of cell identifier.

[0609] As an example, the phrase "sorted by cell identifier" means that the cell identifier of one cell is greater than the cell identifier of another cell, and the order of the one cell is before the order of the other cell.

[0610] As an example, the phrase "sorted by cell identifier" means that the cell identifier of one cell is greater than the cell identifier of another cell, and the order of the one cell is after the order of the other cell.

[0611] As an example, the phrase "sorted by cell identifier" means: sorted according to the cell identifier of the cell corresponding to the octet unit.

[0612] As a sub-implementation of this embodiment, if the cell identifier of the cell corresponding to any bit in one octet is less than the cell identifier of the cell corresponding to any bit in another octet, the order of the cell corresponding to any bit in the one octet is prior to the order of the cell corresponding to any bit in the other octet.

[0613] As a sub-implementation of this embodiment, if the cell identifier of the cell corresponding to any bit in one octet is less than the cell identifier of the cell corresponding to any bit in another octet, the order of the cell corresponding to any bit in the one octet is after the order of the cell corresponding to any bit in the other octet.

[0614] As an example, the phrase "sorted by cell identifier" means: sorted according to the interval to which the cell identifier belongs.

[0615] The K1 cells include all cells whose cell identifiers are not less than 0 and not greater than K1-1; the K2 cells include all cells whose cell identifiers are not less than K1 and not greater than K1+K2-1.

[0616] As an example, the phrase "sorted by cell identifier" means: sorted according to the order of the eight-digit group units to which the cell identifier belongs.

[0617] As an example, the second octet bitmap is the last octet bitmap in the target MAC CE.

[0618] As an example, the second octet bitmap is an octet bitmap at a specified position in the target MAC CE.

[0619] As an example, there is at least one BFR information between any two adjacent octet bitmaps.

[0620] As an example, the size of the first octet bitmap in the first bitmap subset is determined based on the minimum value of the cell identifier of the cell associated with the RS resource group to which each RS resource subgroup belongs in the first RS resource set.

[0621] As an example, the first octet bitmap in the first bitmap subset is determined based on the minimum value of the cell identifier of the cell associated with the RS resource group to which each RS resource subgroup belongs in the first RS resource set.

[0622] As an example, the octet corresponding to the minimum value of the cell identifier of the cell to which each RS resource subgroup in the target RS resource set belongs is the L1st octet bitmap in the target MAC CE; wherein, the target RS resource set includes RS resource subgroups in the first RS resource set except those associated with the first L1-1 octet bitmaps.

[0623] As a sub-implementation of this embodiment, L1 is a positive integer, and L1 is not greater than 4.

[0624] As a sub-implementation of this embodiment, the first L1-1 octet bitmaps are the at least one octet bitmap in the first bitmap subset, and the L1th octet bitmap is the second octet bitmap.

[0625] As a sub-example of this embodiment, the K1 cells are the cells corresponding to all octet units in all octet bitmaps in the first L1-1 octet bitmaps.

[0626] As a sub-implementation of this embodiment, the K2 cells are the cells corresponding to all octet units in all octet bitmaps in the L1st octet bitmap.

[0627] As a sub-example of this embodiment, the first L1-1 octet bitmaps refer to the first octet bitmap to the L1-1th octet bitmaps.

[0628] As an example, the octet corresponding to the minimum value of the cell identifier of the cell associated with each RS resource subgroup in the target RS resource set belongs to the L1st octet bitmap in the target MAC CE; wherein, the target RS resource set includes RS resource subgroups in the first RS resource set except those associated with the first L1-1 octet bitmaps.

[0629] As a sub-example of this embodiment, if the difference between the minimum value of the cell identifier of the cell corresponding to the octet unit and the maximum value of the cell identifier of the corresponding cell in the L1-1th octet bitmap is equal to 1, then the L1th octet bitmap in the target MAC CE is the octet unit.

[0630] As a sub-implementation of this embodiment, if the difference between the minimum value of the cell identifier of the cell corresponding to the octet and the maximum value of the cell identifier of the corresponding cell in the (L1-1)th octet bitmap is greater than 1, the L1th octet bitmap in the target MAC CE further includes at least one octet, where the cell identifier of any cell corresponding to each octet in the at least one octet is less than the cell identifier of any cell corresponding to the octet, and the cell identifier of any cell corresponding to each octet in the at least one octet is not associated with the L1-1th octet bitmap.

[0631] As a sub-implementation of this embodiment, L1 is a positive integer, and L1 is not greater than 4.

[0632] As a sub-implementation of this embodiment, the first L1-1 octet bitmaps are at least one octet bitmap in the first bitmap subset, and the L1th octet bitmap is the second octet bitmap.

[0633] As a sub-example of this embodiment, the K1 cells are the cells corresponding to all octet units in all octet bitmaps in the first L1-1 octet bitmaps.

[0634] As a sub-implementation of this embodiment, the K2 cells are the cells corresponding to all octet units in all octet bitmaps in the L1st octet bitmap.

[0635] As a sub-example of this embodiment, the first L1-1 octet bitmaps refer to the first octet bitmap to the L1-1th octet bitmaps.

[0636] As an example, the octet corresponding to the minimum value of the cell identifier of the cell associated with each RS resource subgroup in the first RS resource set is the first octet bitmap in the first bitmap subset.

[0637] As a sub-implementation of this embodiment, the first bitmap subset does not include another octet, and the cell identifier of any cell corresponding to the other octet is smaller than the cell identifier of any cell corresponding to the octet.

[0638] As an example, the octet corresponding to the minimum value of the cell identifier of the cell associated with each RS resource subgroup in the first RS resource set belongs to the first octet bitmap in the first bitmap subset.

[0639] As a sub-implementation of this embodiment, if the cell identifier of the cell corresponding to the octet is {0, 1, 2, 3, 4, 5, 6, 7}, the first octet bitmap in the first bitmap subset is the octet.

[0640] As a sub-implementation of this embodiment, if the cell identifier of the cell corresponding to the octet is not {0, 1, 2, 3, 4, 5, 6, 7}, the first octet bitmap in the first bitmap subset further includes at least one octet, and the cell identifier of any cell corresponding to each octet in the at least one octet is less than the cell identifier of any cell corresponding to the octet.

[0641] Example 8

[0642] Example 8 illustrates a schematic diagram of a first criterion according to an embodiment of the present application, which includes sorting the octet units according to their priority.

[0643] As an example, the phrase "ordered by octet priority" includes: if a field in the target MAC CE indicates that one octet precedes another octet, any cell associated with the one octet precedes any cell associated with the other octet.

[0644] As an example, the phrase "ordered by octet priority" includes: if a field in the MAC subheader corresponding to the target MAC CE indicates that one octet precedes another octet, any cell associated with the one octet precedes any cell associated with the other octet.

[0645] As an example, each octet bitmap includes at least one octet unit; the first criterion includes sorting the octet units according to their priority.

[0646] As an example, whether each octet is associated with at least one RS resource subgroup with BFR is used to determine the priority of each octet.

[0647] As an example, the phrase "ordered by octet priority" includes: if an octet is associated with at least one RS resource subgroup with BFR, and another octet is not associated with an RS resource subgroup with BFR, the priority of the one octet is higher than the priority of the other octet.

[0648] As an example, the number of RS resource subgroups included in the RS resource group to which each octet is associated with an RS resource subgroup having a BFR is used to determine the priority of each octet.

[0649] As an example, the phrase "ordered by octet priority" includes: if the number of RS resource subgroups included in the RS resource group to which the RS resource subgroup with BFR belongs in one octet is equal to 1, and the number of RS resource subgroups included in the RS resource group to which the RS resource subgroup with BFR belongs in another octet is equal to 2, then the priority of the one octet is higher than the priority of the other octet.

[0650] As an example, the phrase "ordered by octet priority" includes: if an octet is associated with 2 RS resource subgroups in an RS resource group containing a BFR-equivalent RS resource subgroup, and another octet is associated with 1 RS resource subgroup in an RS resource group containing a BFR-equivalent RS resource subgroup, the priority of the one octet is higher than the priority of the other octet.

[0651] As an example, whether each octet is associated with at least one RS resource subgroup with a BFR and the number of RS resource subgroups included in the RS resource group to which each octet is associated with a BFR-equipped RS resource subgroup are used together to determine the priority of each octet.

[0652] As an example, the phrase "ordered by octet priority" includes: if an octet is associated with at least one RS resource subgroup with BFR, and another octet is not associated with an RS resource subgroup with BFR, the priority of the one octet is higher than the priority of the other octet; for at least two octet units associated with at least one RS resource subgroup with BFR, if one of the at least two octet units has 1 RS resource subgroup included in the RS resource subgroup to which it is associated, and the other of the at least two octet units has 2 RS resource subgroups included in the RS resource subgroup to which it is associated, the priority of the one octet unit is higher than the priority of the other octet unit.

[0653] As an example, a field in the target MAC CE is used to indicate the location of an octet.

[0654] As an example, a field in the target MAC CE is used to indicate the position of an octet in the target MAC CE.

[0655] As an example, a field in the target MAC CE indicates the location of one octet cell and another octet cell in the target MAC CE.

[0656] As an example, a field in the target MAC CE is set to 1 to indicate that one octet precedes another octet; a field is set to 0 to indicate that one octet follows another octet.

[0657] As an example, the priority order of the octet units refers to the sequential order of the octet units.

[0658] As an example, an octet is positioned before another octet in the target MAC CE, and the octet has a higher priority than the other octet.

[0659] As an example, a MAC field is used to determine the priority of each octet unit.

[0660] As an example, a MAC field indicates the priority of each octet unit.

[0661] As an example, a MAC domain is a domain in the target MAC CE.

[0662] As an example, the MAC field is a field in the MAC subheader corresponding to the target MAC CE.

[0663] As an example, the MAC field being set to a first value indicates that the priority order of the octet cells from high to low is as follows: octet cells corresponding to cell identifiers {0, 1, 2, 3, 4, 5, 6, 7}, octet cells corresponding to cell identifiers {8, 9, 10, 11, 12, 13, 14, 15}, octet cells corresponding to cell identifiers {16, 17, 18, 19, 20, 21, 22, 23}, and octet cells corresponding to cell identifiers {24, 25, 26, 27, 28, 29, 30, 31}. Group unit; the MAC field is set to a second value to indicate that the priority of the octet group units from high to low is as follows: octet group units corresponding to cell identifiers {16, 17, 18, 19, 20, 21, 22, 23}, octet group units corresponding to cell identifiers {24, 25, 26, 27, 28, 29, 30, 31}, octet group units corresponding to cell identifiers {0, 1, 2, 3, 4, 5, 6, 7}, and octet group units corresponding to cell identifiers {8, 9, 10, 11, 12, 13, 14, 15}.

[0664] As an example, the first criterion includes: sorting each octet according to its priority; if there are at least two octet units with the same priority, sorting the at least two octet units according to their cell identifiers.

[0665] Example 9

[0666] Example 9 illustrates a schematic diagram of a target MAC CE according to an embodiment of this application, including BFR information ordered according to a second criterion, as shown in the attached diagram. Figure 9 As shown.

[0667] In Example 9, the target MAC CE includes the BFR information of the top H RS resource subgroups with BFR in the first RS resource set, sorted according to a second criterion, where H is a positive integer; the second criterion includes sorting at least according to the cell identifier of the associated cell.

[0668] As an example, the associated cell refers to all cells in the first RS resource set.

[0669] As an example, the associated cells refer to a subset of cells in the first RS resource set.

[0670] As one embodiment, the second criterion includes: sorting the RS resource subgroups with BFR in the first RS resource set according to the cell identifier of the associated cell.

[0671] As one embodiment, the second criterion includes: sorting RS resource subgroups in the first RS resource set that have BFRs and are associated with the same octet bitmap according to the cell identifier of the associated cell.

[0672] As an example, the phrase "sorted by cell identifier of associated cell" includes: sorting in ascending order by the cell identifiers of the cells associated with the RS resource group to which the RS resource subgroup belongs.

[0673] As an example, the phrase "sorted by cell identifier of associated cell" includes: sorting in descending order of the cell identifiers of the cells associated with the RS resource group to which the RS resource subgroup belongs.

[0674] As an example, the phrase "sorted by cell identifier of associated cell" includes: if the cell identifier of a cell associated with one RS resource subgroup having BFR is less than the cell identifier of a cell associated with another RS ​​resource subgroup having BFR, the BFR information of the one RS resource subgroup is placed before the BFR information of the other RS ​​resource subgroup.

[0675] As an example, the phrase "sorted by cell identifier of associated cell" includes: if the cell identifier of a cell associated with one RS resource subgroup having BFR is less than the cell identifier of a cell associated with another RS ​​resource subgroup having BFR, the BFR information of the one RS resource subgroup is located after the BFR information of the other RS ​​resource subgroup.

[0676] As one embodiment, the second criterion includes sorting according to the order of the octet bitmap.

[0677] As one embodiment, the second criterion includes: sorting the RS resource subgroups with BFRs in the first RS resource set according to the order of the octet bitmap.

[0678] As one embodiment, the second criterion includes: sorting RS resource subgroups that have BFRs and belong to the first bitmap subset in the first RS resource set according to the order of the octet bitmap.

[0679] As one embodiment, the second criterion includes: sorting RS resource subgroups with BFRs in the first RS resource set according to the order of the octet bitmap; and then sorting RS resource subgroups with BFRs in the first RS resource set according to the cell identifier of the associated cell.

[0680] As an example, the phrase "ordered according to the octet bitmap sequence" includes: if an octet bitmap precedes another octet bitmap in the target MAC CE, all BFR information associated with the one octet bitmap precedes all BFR information associated with the other octet bitmap in the target MAC CE.

[0681] As an example, the phrase "ordered according to the octet bitmap sequence" includes: if an octet bitmap is located before another octet bitmap in the target MAC CE, any BFR information associated with the one octet bitmap is located before any BFR information associated with the other octet bitmap in the target MAC CE.

[0682] As an example, the phrase "ordered according to the octet bitmap sequence" includes: if an octet bitmap is located after another octet bitmap in the target MAC CE, all BFR information associated with the one octet bitmap is located after all BFR information associated with the other octet bitmap in the target MAC CE.

[0683] As an example, the phrase "ordered according to the octet bitmap sequence" includes: if an octet bitmap is located after another octet bitmap in the target MAC CE, any BFR information associated with the one octet bitmap is located after any BFR information associated with the other octet bitmap in the target MAC CE.

[0684] As an example, H is no greater than 32.

[0685] As an example, H is no greater than 31.

[0686] As an example, H is no greater than 64.

[0687] As an example, H is no greater than 63.

[0688] As an example, H is no greater than 62.

[0689] As an example, H is related to the size of the resources granted by the first uplink.

[0690] As an example, H is related to the number of RS resource subgroups with BFR in the first RS resource set.

[0691] As an example, H is related to the cell identifier of the cell associated with the RS resource group to which the RS resource subgroup with BFR in the first RS resource set belongs.

[0692] As an example, H is related to at least one of the following: the size of the resource granted by the first uplink, the number of RS resource subgroups with BFR in the first RS resource set, or the cell identifier of the cell associated with the RS resource group to which the RS resource subgroup with BFR in the first RS resource set belongs.

[0693] As an example, the phrase "the H is related to the size of the resources granted by the first uplink" includes: the H is related to the size of the resources granted by the uplink that are used for the target MAC CE.

[0694] As a sub-example of this embodiment, the size of the uplink grant used for the resources of the target MAC CE is related to the LCP process.

[0695] As an example, H is not greater than the number of RS resource subgroups with BFR in the first RS resource set.

[0696] As an example, if the first uplink grant is capable of accommodating all BFR information associated with all RS resource subgroups that have BFR in the first RS resource set, then H is equal to the number of RS resource subgroups that have BFR in the first RS resource set.

[0697] As an example, if the first uplink grant cannot accommodate all BFR information associated with all RS resource subgroups that have BFR in the first RS resource set, then H is less than the number of RS resource subgroups that have BFR in the first RS resource set.
