[0071] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0072] To facilitate a better understanding of the embodiments of the present application, a power headroom report (PHR) mechanism related to the present application is described.

[0073] Regardless of the PHR type 1 (Type 1) or type 3 (Type 3), it will be reported by the terminal device to the network device through the Physical Uplink Shared Channel (PUSCH).

[0074] Type 1 PHR is used to report the power headroom of the terminal device for sending PUSCH. Type 1 PHR is divided into: PHR based on the actual sent PUSCH and PHR based on the reference PUSCH.

[0075] In some embodiments, the PHR based on the actually transmitted PUSCH is the difference between the maximum transmit power of the terminal device and the actually transmitted PUSCH power, as shown in Formula 1.

[0076]

[0077] In formula 1, the unit of pH is dB;

[0078] b: indicates bandwidth part (BWP);

[0079] f: indicates a carrier (e.g., an uplink (UL) carrier or a supplementary uplink carrier (SUL) within a cell);

[0080] c: indicates the serving cell;

[0081] i: indicates transmission occasion;

[0082] j: indicates the parameter configuration index;

[0083] q d : Index of the reference signal used for path loss measurement;

[0084] l: Index of closed-loop power control adjustment status.

[0085] The open-loop power control parameters in the above formula 1 include:

[0086] P O_PUSCH，b，f，c (j): represents the target received power;

[0087] α b，f，c (j): weighting factor representing path loss;

[0088] PL b，f，c (q d ): represents the path loss value measured according to the reference signal for path loss;

[0089] The closed-loop power control parameters in the above formula 1 include:

[0090] f b，f，c (i, l): indicates the closed-loop power control adjustment state, including cumulative closed-loop power control (acting on the power control accumulated value through the accumulator) and absolute closed-loop power control (acting directly on the power adjustment value);

[0091] P CMAX，f，c (i): indicates the maximum transmit power of the terminal device on carrier f in serving cell c;

[0092] Indicates the transmission bandwidth of the PUSCH (the number of resource blocks (RBs) allocated).

[0093] In some embodiments, the PHR based on the reference PUSCH is the difference between the maximum transmit power of the terminal device and the reference PUSCH power. It can be understood that the carrier does not transmit PUSCH at the time of calculating the PHR, as shown in Formula 2.

[0094]

[0095] In formula 2, It represents the maximum transmit power determined based on a specific parameter value. The parameters identical to those in the above formula 1 have the same meanings as above and are not repeated here.

[0096] Type 3 PHR is used to report the power headroom of the terminal device's Sounding Reference Signal (SRS) and is reported only on carriers without PUSCH configured. Type 3 PHR is divided into: PHR based on the actual transmitted SRS and PHR based on the reference SRS.

[0097] In some embodiments, the PHR based on the actually transmitted SRS is the difference between the maximum transmit power of the terminal device and the actually transmitted SRS power, as shown in Formula 3.

[0098]

[0099] In Formula 3, the same parameters as those in Formula 1 have the same meanings as above and are not repeated here.

[0100] qs : Indicates the index of the SRS resource set;

[0101] h b，f，c (i, l): indicates the adjustment status of SRS closed-loop power control.

[0102] The power control of SRS is performed based on an SRS resource set, and the SRS resources in an SRS resource set use the same power control parameters.

[0103] Open-loop power control parameter P O_SRS，b，f，c (q s ) and α SRS，b，f，c (q s ) and the SRS resource set index used to calculate the path loss PL b，f，c (q d ) are all based on the SRS resource set configuration and are configured by RRC signaling.

[0104] h b，f，c (i, l) can be indicated by RRC signaling to use the same closed-loop power adjustment state as the PUSCH associated with the closest time domain, or to use an independent closed-loop power control adjustment state.

[0105] In some embodiments, the PHR based on the reference SRS is the difference between the maximum transmit power of the terminal device and the reference SRS power. It can be understood that the carrier does not transmit the SRS at the time of calculating the PHR, as shown in Formula 4.

[0106]

[0107] In Formula 4, It represents the maximum transmit power determined based on a specific parameter value. The parameters identical to those in the above formula 1 have the same meanings as above and are not repeated here.

[0108] In order to facilitate a better understanding of the embodiments of the present application, the reporting of PHRs of multiple cells related to the present application is explained.

[0109] If the terminal device sends PUSCH in multiple cells simultaneously, and the subcarrier spacing of the activated bandwidth part (BWP) of different cells is different, then:

[0110] When the serving cell 1 (cell 1) where the PUSCH carrying PHR is located has a subcarrier spacing (SCS) of μ1 for the activated BWP1 of cell 1, and another serving cell 2 (cell 2) that sends PUSCH has a subcarrier spacing (SCS) of μ2 for the activated BWP2 of cell 2. If μ1<μ2, then the first time slot that completely overlaps with the multiple time slots of cell 2 corresponding to the time slot carrying PUSCH of cell 1, cell 2 reports the PHR of the time slot, as shown in Figure 2, μ1=15KHz, μ2=60KHz; if μ1=μ2, the first time slot of cell 2 that overlaps with the time slot carrying PUSCH of cell 1, cell 2 reports the PHR of the time slot, as shown in Figure 3, μ1=15KHz, μ2=15KHz.

[0111] To facilitate a better understanding of the embodiments of the present application, the uplink multi-antenna panel (panel) / transmission reception point (TRP) transmission related to the present application is described.

[0112] If the terminal is configured with multiple panels and supports simultaneous transmission of uplink information on multiple panels, multiple uplink information can be transmitted simultaneously on multiple panels, as shown in Figure 4, to improve the uplink spectrum efficiency. The uplink transmission of the same multiple panels / TRPs can be scheduled through a single downlink control information (DCI) or through multiple DCIs. The multiple PUSCHs sent by the UE are in a unified transmission configuration indicator (TCI) scenario. The multiple PUSCHs are associated with different TCI states and can be non-overlapping, partially overlapping, or completely overlapping in the time domain.

[0113] To facilitate a better understanding of the embodiments of the present application, the processing of conflicts between the physical uplink control channel (PUCCH) and the PUSCH related to the present application is described.

[0114] The UE can only send a maximum of 2 PUCCHs in a time-division manner in one time slot, and at least one of them is a short-format PUCCH. When multiple PUCCHs overlap in the time domain, the timing relationship is set to allow the UE to have enough time to determine whether different PUCCHs need to be multiplexed, and if multiplexing is required, consider the time required to re-pack the uplink control information (UCI). In order to reduce interference between UE uplink transmissions in NR, when PUCCH and PUSCH overlap in the time domain, it supports the UCI information carried in PUCCH to be carried on PUSCH for transmission, and certain timing requirements need to be met during multiplexing.

[0115] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0116] Multiple PUSCHs scheduled by multiple DCIs can overlap, partially overlap, or not overlap in the time domain, as shown in Figure 5. The PUCCHs corresponding to PDSCHs associated with different spatial parameters can be fed back jointly or independently. If fed back independently, the PUCCHs are sent using spatial parameters 1 and 2, respectively. Furthermore, when multiple panels are transmitted simultaneously, the PUCCHs can be transmitted simultaneously using a single DCI indication or using multiple DCI indications.

[0117] Question 1. As shown in Figure 6, if PUCCH and PUSCH collide in the time domain, the PUCCH (or the UCI information carried on the PUCCH) is multiplexed onto the PUSCH for transmission according to the multiplexing rules. How should PUCCH and PUSCH associated with different spatial parameters be handled? This is shown in Scenario 1 and Scenario 2 in Figure 5. In Scenario 1, PUCCH1 associated with spatial parameter 1 can be multiplexed into PUSCH1 with the same spatial parameter, and PUSCH1 and PUSCH2 can be transmitted simultaneously. In Scenario 2, PUCCH1 associated with spatial parameter 1 can be multiplexed into PUSCH1 with the same spatial parameter, and PUCCH2 associated with spatial parameter 2 can be multiplexed into PUSCH2 with the same spatial parameter, and PUSCH1 and PUSCH2 can be transmitted simultaneously. However, for other scenarios, such as those shown in Scenario 1 and Scenario 2 of Figure 7 , PUCCH1 associated with spatial parameter 1 in Scenario 1 can be multiplexed with PUSCH1 of the same spatial parameter, but PUSCH1 and PUCCH2 associated with spatial parameter 2 also overlap in the time domain; and PUSCH1 associated with spatial parameter 1 and PUCCH1 associated with spatial parameter 2 overlap in the time domain in Scenario 2. That is, as shown in Figure 7 , PUCCH2 in Scenario 1 may not find a PUSCH with the same spatial parameter to multiplex with, and PUCCH1 in Scenario 2 may not find a PUSCH with the same spatial parameter to multiplex with. How to handle PUCCHs and PUSCHs associated with different spatial parameters is a problem that needs to be solved.

[0118] Question 2: How to report PHR in a multi-antenna panel simultaneous interpretation scenario is a problem that needs to be solved.

[0119] Based on the above-mentioned problem 1, the present application proposes a scheme for PUCCH multiplexing transmission. For some PUCCHs that have conflicts in the time domain and cannot be multiplexed with PUSCHs associated with the same spatial parameters, the terminal device can multiplex the UCI information carried in the PUCCH to the PUSCH associated with specific spatial parameters, or the terminal device can discard the PUCCH, or the terminal device can discard the PUSCH that overlaps with the PUCCH in the time domain, thereby optimizing PUCCH transmission.

[0120] Based on the above-mentioned question 2, this application proposes a PHR reporting solution, whereby the terminal device can report the PHR corresponding to the spatial parameter information, thereby realizing PHR reporting in a multi-antenna panel (panel) simultaneous interpretation scenario.

[0121] The technical solution of this application is described in detail below through specific embodiments.

[0122] FIG8 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG8 , the wireless communication method 200 may include at least part of the following contents:

[0123] S210, the terminal device multiplexes the UCI information carried by P PUCCHs out of the M PUCCHs into PUSCHs among the N PUSCHs that are associated with the same spatial parameters as the P PUCCHs, where the M PUCCHs overlap with the N PUSCHs in the time domain.

[0165] In some embodiments, the terminal device multiplexes the UCI information carried in the S PUCCHs into the PUSCH associated with the first target spatial parameter in the N PUSCHs, including:

[0166] In an ideal backhaul scenario, the terminal device multiplexes the UCI information carried in the S PUCCHs into the PUSCH associated with the first target spatial parameter in the N PUSCHs.

[0167] It should be noted that, when a terminal device communicates with multiple TRPs, the backhaul connection between TRPs may be ideal or non-ideal. In an ideal backhaul, information exchange can be performed quickly and dynamically between TRPs, that is, in an ideal backhaul scenario, the transmission delay of information exchange is small, such as the transmission delay of information exchange is less than a first preset value, wherein the first preset value is agreed upon by the protocol, or the first preset value is configured by the network device. In a non-ideal backhaul, due to the large delay, information exchange can only be performed quasi-statically between TRPs, that is, in a non-ideal backhaul scenario, the transmission delay of information exchange is large, such as the transmission delay of information exchange is greater than a second preset value, wherein the second preset value is agreed upon by the protocol, or the second preset value is configured by the network device. Therefore, in an ideal backhaul scenario, the terminal device multiplexes the UCI information carried in the S PUCCHs to the PUSCH associated with the first target spatial parameter in the N PUSCHs.

[0168] Therefore, in this embodiment, information is not discarded, and normal transmission of the PUCCH and the PUSCH can be guaranteed.

[0169] It should be understood that ideal backhaul can be one with very high throughput and very low latency, such as backhaul in point-to-point fiber optic connections. Non-ideal backhaul, for example, has longer latency, such as Digital Subscriber Line (DSL), microwave, and other backhaul options (e.g., relays). Ideal backhaul corresponds to scenarios with high throughput and low latency, such as fiber optics. Non-ideal backhaul, for example, has higher latency and lower throughput than ideal backhaul, such as microwaves.

[0170] In some embodiments, the terminal device may transmit the first uplink information according to a priority order. In other words, the terminal device discards or ignores at least one of the following according to the priority order: some or all of the S PUCCHs, and some or all of the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0171] In some embodiments, when the priority index associated with the i-th PUCCH is higher than the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the first uplink information does not include the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain; and / or,

[0172] In a case where the priority index associated with the i-th PUCCH is lower than the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the first uplink information does not include the i-th PUCCH;

[0173] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0174] In some embodiments, when the priority index associated with the i-th PUCCH is higher than the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device discards or ignores the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain; and / or,

[0175] In a case where the priority index associated with the i-th PUCCH is lower than the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device discards or ignores the i-th PUCCH;

[0176] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0177] That is, the terminal device can discard or ignore PUSCH or PUCCH based on the priority index. For example, the terminal device can discard or ignore all PUCCHs in S PUCCHs, or the terminal device can discard or ignore all PUSCHs in N PUSCHs that overlap with S PUCCHs in the time domain, or the terminal device can discard or ignore some PUCCHs in S PUCCHs and some PUSCHs in N PUSCHs that overlap with S PUCCHs in the time domain.

[0178] Optionally, the priority index associated with the PUCCH may be configured or indicated by the network device, and / or the priority index associated with the PUSCH may be configured or indicated by the network device.

[0179] In some embodiments, when the priority of UCI information carried in the i-th PUCCH is higher than the priority of information carried in the PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the first uplink information does not include the PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain; and / or,

[0180] When the priority of UCI information carried in the i-th PUCCH is lower than the priority of information carried in a PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the first uplink information does not include the i-th PUCCH;

[0181] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0182] In some embodiments, when the priority of UCI information carried in the i-th PUCCH is higher than the priority of information carried in the PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device discards or ignores the PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain; and / or,

[0183] If the priority of the UCI information carried in the i-th PUCCH is lower than the priority of the information carried in the PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device discards or ignores the i-th PUCCH;

[0184] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0185] That is, the terminal device can discard or ignore PUSCH or PUCCH based on the priority of the UCI information carried in the PUCCH and the priority of the information carried in the PUSCH. For example, the terminal device can discard or ignore all PUCCHs in the S PUCCHs, or the terminal device can discard or ignore all PUSCHs in the N PUSCHs that overlap with the S PUCCHs in the time domain, or the terminal device can discard or ignore part of the PUCCHs in the S PUCCHs and part of the PUSCHs in the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0186] In some embodiments, the information carried by the PUSCH includes at least one of the following: Hybrid Automatic Repeat reQuest (HARQ), Channel State Information (CSI), and data.

[0187] In some embodiments, the UCI information carried by the PUCCH includes one or more of: HARQ information, CSI information, SR information, and LRR.

[0188] In some embodiments, when the priority index associated with the i-th PUCCH is the same as the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device determines the priority of the i-th PUCCH and the priority of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain according to the content carried by the i-th PUCCH and the content carried by the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain;

[0189] When the priority of the i-th PUCCH is higher than the priority of the PUSCH that overlaps with the i-th PUCCH in the time domain among the N PUSCHs, the first uplink information does not include the PUSCH that overlaps with the i-th PUCCH in the time domain among the N PUSCHs; and / or, when the priority of the i-th PUCCH is lower than the priority of the PUSCH that overlaps with the i-th PUCCH in the time domain among the N PUSCHs, the first uplink information does not include the i-th PUCCH;

[0190] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0191] In some embodiments, when the priority index associated with the i-th PUCCH is the same as the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device determines the priority of the i-th PUCCH and the priority of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain according to the content carried by the i-th PUCCH and the content carried by the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain;

[0192] In a case where the priority of the i-th PUCCH is higher than the priority of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device discards or ignores the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain; and / or, in a case where the priority of the i-th PUCCH is lower than the priority of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device discards or ignores the i-th PUCCH;

[0193] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0194] In some embodiments, the priority of the PUCCH carrying at least one of the hybrid automatic repeat request-acknowledgement (HARQ-ACK), scheduling request (SR) and link recovery request (LRR) is higher than the priority of the PUSCH carrying channel state information (CSI).

[0195] In some embodiments, a PUCCH carrying at least one of HARQ-ACK, SR, and LRR has a higher priority than a PUSCH not carrying HARQ-ACK.

[0196] In some embodiments, the priority of the PUSCH carrying HARQ-ACK is higher than the priority of the PUCCH carrying CSI.

[0197] In some embodiments, the priority of a PUCCH carrying CSI is higher than the priority of a PUSCH not carrying CSI.

[0198] In some embodiments, the priority of a PUCCH carrying at least one of HARQ-ACK, SR, and LRR is higher than the priority of a PUSCH not carrying HARQ-ACK and CSI.

[0199] In some embodiments, the priority of the PUCCH carrying CSI is higher than the priority of the PUSCH carrying CSI.

[0200] In some embodiments, the priority of a PUSCH carrying HARQ-ACK is higher than the priority of a PUCCH carrying at least one of SR and LRR.

[0201] In some embodiments, the priority of a PUSCH carrying CSI is higher than the priority of a PUCCH carrying CSI.

[0202] In some embodiments, the order of priority from highest to lowest is as follows:

[0203] Highest priority: PUCCH carrying HARQ-ACK and / or SR, and / or LRR has higher priority; or PUSCH carrying HARQ-ACK has higher priority;

[0204] Second highest priority: PUCCH carrying CSI; or, PUSCH carrying CSI;

[0205] Lowest priority: PUSCH that does not carry UCI information.

[0206] In the case where a terminal device communicates with multiple TRPs, the backhaul connection between the TRPs may be ideal or non-ideal. Under ideal backhaul, the TRPs can exchange information quickly and dynamically, that is, in an ideal backhaul scenario, the transmission delay of the information interaction is small, such as the transmission delay of the information interaction is less than a first preset value, wherein the first preset value is agreed upon by the protocol, or the first preset value is configured by the network device. Under non-ideal backhaul, due to the large delay, the TRPs can only exchange information quasi-statically, that is, in a non-ideal backhaul scenario, the transmission delay of the information interaction is large, such as the transmission delay of the information interaction is greater than a second preset value, wherein the second preset value is agreed upon by the protocol, or the second preset value is configured by the network device. Therefore, in this embodiment, in order to avoid the inability of TRPs to exchange UCI information due to non-ideal backhaul, rules are formulated to ensure the normal transmission of high-priority PUCCH or PUSCH.

[0207] In some embodiments, the terminal device transmits the first uplink information, and the first uplink information does not include the PUCCH associated with the second target spatial parameter in the S PUCCHs, and the PUSCH associated with the second target spatial parameter in the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0208] In some embodiments, the terminal device discards or ignores at least one of the following: the PUCCH associated with the second target spatial parameter in the S PUCCHs, and the PUSCH associated with the second target spatial parameter in the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0209] That is, the terminal device may discard or ignore transmissions associated with specific spatial parameters (PUCCH and / or PUSCH).

[0210] In some embodiments, a transmission scheme of the S PUCCHs is a single frequency network (SFN), and / or a transmission scheme of a PUSCH among the N PUSCHs that overlaps with the S PUCCHs in the time domain is SFN.

[0211] That is, when the transmission scheme of the S PUCCHs is SFN, and / or the transmission scheme of the PUSCHs among the N PUSCHs that overlap with the S PUCCHs in the time domain is SFN, the first uplink information does not include at least one of the following: the PUCCH associated with the second target spatial parameter among the S PUCCHs, and the PUSCH associated with the second target spatial parameter among the N PUSCHs that overlap with the S PUCCHs in the time domain; or, when the transmission scheme of the S PUCCHs is SFN, and / or the transmission scheme of the PUSCHs among the N PUSCHs that overlap with the S PUCCHs in the time domain is SFN, the terminal device discards or ignores at least one of the following: the PUCCH associated with the second target spatial parameter among the S PUCCHs, and the PUSCH associated with the second target spatial parameter among the PUSCHs among the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0212] In some embodiments, the second target space parameter is predefined (such as agreed upon by protocol), or the second target space parameter is preconfigured (such as pre-configured or semi-statically configured), or the second target space parameter is configured by the network device (such as dynamically configured).

[0213] In some embodiments, in the SFN transmission scheme, repeated transmissions of uplink information (such as PUCCH and / or PUSCH) are associated with different spatial parameters, respectively. For example, one repeated transmission of uplink information is associated with a first spatial parameter, and another repeated transmission of uplink information is associated with a second spatial parameter. Specifically, taking the uplink information as PUSCH and the spatial parameter as the TCI state as an example, as shown in FIG9 , repeated transmissions of a PUSCH are sent to different TRPs through different antenna panels (panels) of the terminal device. For example, the PUSCH sent through panel1 of the terminal device is associated with the first TCI state and is recorded as the first PUSCH; the PUSCH sent through panel2 of the terminal device is associated with the second TCI state and is recorded as the second PUSCH.

[0214] Therefore, in this embodiment, in order to avoid the inability to exchange UCI information between TRPs due to non-ideal backhaul, a rule is formulated to discard the PUCCH or PUSCH associated with the second target spatial parameter.

[0215] In some embodiments, when the i-th PUCCH is a PUCCH repeatedly transmitted in the time domain, the first uplink information does not include the current transmission of the i-th PUCCH; and / or, when the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain is a PUSCH repeatedly transmitted in the time domain, the first uplink information does not include the current transmission of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain;

[0216] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0217] In some embodiments, when the i-th PUCCH is a PUCCH repeatedly transmitted in the time domain, the terminal device abandons or ignores the current transmission of the i-th PUCCH; and / or, when the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain is a PUSCH repeatedly transmitted in the time domain, the terminal device abandons or ignores the current transmission of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain;

[0218] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0219] Therefore, in this embodiment, in order to avoid the inability to exchange UCI information between TRPs due to non-ideal backhaul, a rule is formulated so that the PUCCH repeatedly transmitted in the time domain abandons the current transmission, and / or the PUSCH repeatedly transmitted in the time domain abandons the current transmission.

[0220] In some embodiments, when the priority index associated with the i-th PUCCH is the same as the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, and the transmission scheme of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain is space division multiplexing (SDM), the first uplink information does not include the i-th PUCCH;

[0221] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0222] In some embodiments, when the priority index associated with the i-th PUCCH is the same as the priority index associated with the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain, and the transmission scheme of the PUSCH in the N PUSCHs that overlaps with the i-th PUCCH in the time domain is SDM, the terminal device discards or ignores the i-th PUCCH;

[0223] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0224] In some embodiments, the SDM transmission scheme includes SDM transmission scheme A and SDM transmission scheme B.

[0225] SDM transmission scheme A: Different transmission layers of uplink information (such as PUCCH and / or PUSCH) are respectively associated with different spatial parameters. For example, part of the transmission layer of the uplink information is associated with the first spatial parameter, and another part of the transmission layer of the uplink information is associated with the second spatial parameter. Specifically, as shown in Figure 9, in SDM transmission scheme A, taking the uplink information as PUSCH and the spatial parameter as the TCI state as an example, different transmission layers of a PUSCH can be sent to different TRPs through different panels of the terminal device. For example, different transmission layers sent to different TRPs through different panels can be considered as different PUSCHs. For example, part of the transmission layer of the PUSCH sent through panel1 is associated with the first TCI state, recorded as the first PUSCH; another part of the transmission layer of the PUSCH sent through panel2 is associated with the second TCI state, recorded as the second PUSCH. It can be understood that the first PUSCH and the second PUSCH are different transmission layers of the same transmission block (TB).

[0226] SDM transmission scheme B: repeated transmission of uplink information (such as PUCCH and / or PUSCH) (which can be different redundancy versions (RV)) is associated with different spatial parameters, for example, one repeated transmission of uplink information is associated with the first spatial parameter, and another repeated transmission of uplink information is associated with the second spatial parameter. Specifically, as shown in Figure 9, in SDM transmission scheme B, taking the uplink information as PUSCH and the spatial parameter as TCI state as an example, the repeated transmission of a PUSCH is sent to different TRPs through different panels of the terminal device. For example, the PUSCH sent by panel1 of the terminal device is associated with the first TCI state and is recorded as the first PUSCH; the PUSCH sent by panel2 of the UE is associated with the second TCI state and is recorded as the second PUSCH. It can be understood that the first PUSCH and the second PUSCH are repeated transmissions of the same TB.

[0227] In some embodiments, when the first uplink information does not include a PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain, and UCI information carried by at least one PUCCH among the M PUCCHs is multiplexed and transmitted on a PUSCH among the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the first uplink information includes the i-th PUCCH and the at least one PUCCH;

[0228] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0229] In some embodiments, when the terminal device discards or ignores the PUSCH of the N PUSCHs that overlaps with the i-th PUCCH in the time domain, and UCI information carried in at least one PUCCH of the M PUCCHs is multiplexed and transmitted on the PUSCH of the N PUSCHs that overlaps with the i-th PUCCH in the time domain, the terminal device transmits the i-th PUCCH and the at least one PUCCH;

[0230] The i-th PUCCH belongs to the S PUCCHs, i is a positive integer, and 1≤i≤S.

[0231] Therefore, in this embodiment, it is avoided that the UCI information multiplexed on the PUSCH cannot be transmitted due to the abandonment of the PUSCH.

[0232] In some embodiments, in a non-ideal backhaul scenario, the terminal device transmits the first uplink information.

[0233] In some embodiments, in a non-ideal backhaul scenario, the terminal device discards or ignores at least one of the following: part or all of the S PUCCHs, and part or all of the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0234] It should be noted that, when a terminal device communicates with multiple TRPs, the backhaul connection between TRPs may be ideal or non-ideal. In an ideal backhaul, information exchange can be performed quickly and dynamically between TRPs, that is, in an ideal backhaul scenario, the transmission delay of information exchange is small, such as the transmission delay of information exchange is less than a first preset value, wherein the first preset value is agreed upon by the protocol, or the first preset value is configured by the network device. In a non-ideal backhaul, due to the large delay, information exchange can only be performed quasi-statically between TRPs, that is, in a non-ideal backhaul scenario, the transmission delay of information exchange is large, such as the transmission delay of information exchange is greater than a second preset value, wherein the second preset value is agreed upon by the protocol, or the second preset value is configured by the network device. Therefore, in a non-ideal backhaul scenario, the terminal device abandons or ignores at least one of the following: part or all of the S PUCCHs, and part or all of the N PUSCHs that overlap with the S PUCCHs in the time domain.

[0235] Therefore, in an embodiment of the present application, the terminal device multiplexes the UCI information carried in the S PUCCHs to the PUSCH associated with the first target spatial parameter in the N PUSCHs, or the first uplink information transmitted by the terminal device does not include at least one of the following: part or all of the PUCCHs in the S PUCCHs, part or all of the PUSCHs in the N PUSCHs that overlap with the S PUCCHs in the time domain. That is, for some PUCCHs that conflict in the time domain and cannot be multiplexed with a PUSCH associated with the same spatial parameters, the terminal device can multiplex the UCI information carried in the PUCCH to the PUSCH associated with a specific spatial parameter, or the terminal device can discard or ignore the PUCCH, or the terminal device can discard or ignore the PUSCH that overlaps with the PUCCH in the time domain, thereby optimizing PUCCH transmission.

[0272] In some embodiments, the above S310 may specifically include:

[0273] The terminal device reports a PHR corresponding to a first target space parameter among multiple space parameters; or

[0274] The terminal device reports a PHR corresponding to each of the multiple spatial parameters; or

[0275] The terminal device reports the total PHR corresponding to each of the multiple spatial parameters.

[0276] In some embodiments, the multiple space parameters may be space parameters configured by the network device, or the multiple space parameters may be space parameters supported by the terminal device. For example, the multiple space parameters include a first space parameter and a second space parameter.

[0277] In some embodiments, the first target space parameter is predefined (such as agreed upon by protocol), or the first target space parameter is preconfigured (such as pre-configured or semi-statically configured), or the first target space parameter is configured by the network device (such as dynamically configured).

[0278] In some embodiments, when the terminal device reports a PHR corresponding to a first target spatial parameter among multiple spatial parameters, the PHR corresponding to the first target spatial parameter is carried through a first PUSCH;

[0279] The first PUSCH is a PUSCH associated with the first target spatial parameter, or the first PUSCH is a PUSCH transmitted first in the time domain among the PUSCHs associated with the multiple spatial parameters.

[0280] For example, as shown in Figure 11, the first target spatial parameter is spatial parameter 1. In scenario 1, the first PUSCH is the PUSCH associated with spatial parameter 1. That is, in scenario 1, the PHR corresponding to spatial parameter 1 is carried by the PUSCH associated with spatial parameter 1. In scenario 2, the first PUSCH is the PUSCH that is transmitted first in the time domain among the PUSCHs associated with spatial parameters 1 and 2 respectively. That is, in scenario 2, since the PUSCH associated with spatial parameter 2 is transmitted first in the time domain, the PHR corresponding to spatial parameter 1 is carried by the PUSCH associated with spatial parameter 2.

[0281] In some embodiments, the PHR corresponding to the first target space parameter is an actual PHR, or the PHR corresponding to the first target space parameter is a virtual PHR.

[0282] In some embodiments, if the scheduling information or configuration information corresponding to the PUSCH associated with the first target spatial parameter is earlier than a first time interval before the first symbol of the first PUSCH, the PHR corresponding to the first target spatial parameter is the actual PHR.

[0283] In some embodiments, the first time interval is a scheduling interval from PDCCH to PUSCH, or the first time interval is a processing time of PUSCH.

[0284] In some embodiments, if the PUSCH associated with the first target spatial parameter and the first PUSCH are transmitted in the same time unit, the PHR corresponding to the first target spatial parameter is the actual PHR. Optionally, the time unit can be one of the following: a time slot, a symbol, a subframe, a microslot or a minislot, an absolute time in seconds (s), milliseconds (ms), or microseconds (μs).

[0285] In some embodiments, the first PUSCH is a dynamically scheduled PUSCH or a non-scheduled PUSCH.

[0286] In some embodiments, the PHR corresponding to the first target space parameter is calculated based on a power control parameter associated with the first target space parameter.

[0287] In some embodiments, when the terminal device reports a PHR corresponding to each of the multiple spatial parameters, the PHR corresponding to each of the multiple spatial parameters is carried by the second PUSCH; or,

[0288] In the case where the terminal device reports a total PHR corresponding to each of the multiple spatial parameters, the total PHR corresponding to each of the multiple spatial parameters is carried by the second PUSCH;

[0289] The second PUSCH is a PUSCH associated with a second target spatial parameter among the multiple spatial parameters, or the second PUSCH is a PUSCH transmitted first in the time domain among the PUSCHs respectively associated with the multiple spatial parameters.

[0290] In some embodiments, the second target spatial parameter is a spatial parameter for which a PHR associated with multiple spatial parameters satisfies a trigger condition. For example, if a PHR associated with a first spatial parameter satisfies a trigger condition, the PHR corresponding to each spatial parameter is reported, or the PHR associated with all spatial parameters is reported and carried on a PUSCH associated with the first spatial parameter.

[0291] For example, as shown in FIG12 , in scenario 1, the PUSCH associated with spatial parameter 1 is transmitted first in the time domain, and the second PUSCH is the PUSCH associated with spatial parameter 1. That is, in scenario 1, the PHRs corresponding to spatial parameters 1 and 2 are respectively carried by the PUSCH associated with spatial parameter 1, or the total PHRs corresponding to spatial parameters 1 and 2 are carried by the PUSCH associated with spatial parameter 1. As shown in FIG12 , in scenario 2, the PHR associated with spatial parameter 2 meets the triggering condition. That is, in scenario 2, the second PUSCH is the PUSCH associated with spatial parameter 2, and the PHRs corresponding to spatial parameters 1 and 2 are respectively carried by the PUSCH associated with spatial parameter 2, or the total PHRs corresponding to spatial parameters 1 and 2 are carried by the PUSCH associated with spatial parameter 2.

[0292] In some embodiments, the PHR corresponding to each of the multiple spatial parameters is an actual PHR, or the PHR corresponding to each of the multiple spatial parameters is a virtual PHR.

[0293] For example, when the terminal device reports a PHR corresponding to each of multiple spatial parameters, assuming that the multiple spatial parameters include a first spatial parameter and a second spatial parameter, the PHR reported by the terminal device may include one of the following combinations:

[0294] {Actual PHR, Actual PHR},

[0295] {virtual PHR, virtual PHR},

[0296] {actual PHR, virtual PHR},

[0297] {virtual PHR, actual PHR}.

[0298] In some embodiments, when the terminal device reports the total PHR corresponding to each of the multiple spatial parameters, the PHR reported by the terminal device may be one of the following:

[0299] Total actual PHR, total virtual PHR, total actual PHR + virtual PHR.

[0300] In some embodiments, if the scheduling information or configuration information corresponding to the PUSCH associated with the i-th spatial parameter is earlier than the first time interval before the first symbol of the second PUSCH, the PHR corresponding to the i-th spatial parameter is the actual PHR; wherein the i-th spatial parameter belongs to the multiple spatial parameters, and i is a positive integer.

[0301] In some embodiments, the first time interval is a scheduling interval from PDCCH to PUSCH, or the first time interval is a processing time of PUSCH.

[0302] In some embodiments, if the PUSCH associated with the i-th spatial parameter and the second PUSCH are transmitted in the same time unit, the PHR corresponding to the i-th spatial parameter is the actual PHR; wherein the i-th spatial parameter belongs to the multiple spatial parameters, and i is a positive integer. Optionally, the time unit can be one of the following: a time slot, a symbol, a subframe, a mini-slot or a mini-slot, and an absolute time of seconds (s), milliseconds (ms), or microseconds (μs).

[0303] In some embodiments, the PHR corresponding to the i-th spatial parameter is calculated based on a power control parameter associated with the i-th spatial parameter; wherein the i-th spatial parameter belongs to the multiple spatial parameters, and i is a positive integer.

[0304] In some embodiments, the second PUSCH is a dynamically scheduled PUSCH or a non-scheduled PUSCH.

[0305] In some embodiments, the terminal device receives first configuration information;

[0306] The first configuration information includes at least a PHR reporting method and / or PHR mode information;

[0307] The PHR is reported in a manner that the PHR corresponds to the first target spatial parameter among the multiple spatial parameters, or the PHR is reported in a manner that the PHR corresponds to each of the multiple spatial parameters, or the PHR is reported in a manner that the total PHR corresponds to each of the multiple spatial parameters;

[0308] The PHR mode information is used to indicate that the configuration information of the PHR corresponding to the first target spatial parameter is effective, or the PHR mode information is used to indicate that the configuration information of the PHR corresponding to the multiple spatial parameters are all effective.

[0309] In some embodiments, the first configuration information is configuration information of a PHR sent by a network device.

[0310] In some embodiments, the first configuration information is carried by at least one of the following:

[0311] Radio Resource Control (RRC) signaling, Downlink Control Information (DCI), Media Access Control Control Element (MAC CE) signaling.

[0312] In some embodiments, after receiving the first configuration information, the terminal device determines to trigger PHR reporting.

[0313] For example, when the terminal device reports the PHR corresponding to the first target space parameter among multiple space parameters, the terminal device determines to trigger the PHR report, which can be understood as the terminal device determines to trigger the PHR report corresponding to the first target space parameter.

[0314] For example, when the terminal device reports a PHR corresponding to each of multiple spatial parameters, the terminal device determines to trigger the PHR report, which can be understood as the terminal device determines to trigger the PHR report corresponding to any spatial parameter.

[0315] For example, when the terminal device reports the total PHR corresponding to each spatial parameter among multiple spatial parameters, the terminal device determines to trigger the PHR report, which can be understood as the terminal device determines to trigger the PHR report corresponding to any spatial parameter, or the terminal device determines to trigger the PHR report corresponding to all spatial parameters.

[0316] In some embodiments, when the first configuration information at least includes the reporting method of the PHR, the above S310 may specifically include: the terminal device reports the PHR corresponding to the spatial parameter information according to the reporting method of the PHR.

[0317] In some embodiments, the reporting method of the PHR is determined based on the capability information of the terminal device;

[0318] The capability information of the terminal device includes the PHR reporting method supported by the terminal device;

[0319] Among them, the PHR reporting methods supported by the terminal device include at least one of the following: reporting the PHR corresponding to the first target spatial parameter among the multiple spatial parameters, reporting the PHR corresponding to each spatial parameter among the multiple spatial parameters, and reporting the total PHR corresponding to each spatial parameter among the multiple spatial parameters.

[0320] For example, when the terminal device at least supports reporting the PHR corresponding to the first target spatial parameter among the multiple spatial parameters, the reporting method of the PHR indicated by the network device in the first configuration information is to report the PHR corresponding to the first target spatial parameter among the multiple spatial parameters.

[0321] For example, when the terminal device at least supports reporting the PHR corresponding to each of the multiple spatial parameters, the reporting method of the PHR indicated by the network device in the first configuration information is to report the PHR corresponding to each of the multiple spatial parameters.

[0322] For another specific example, when the terminal device at least supports reporting the total PHR corresponding to each of the multiple spatial parameters, the PHR reporting method indicated by the network device in the first configuration information is to report the total PHR corresponding to each of the multiple spatial parameters.

[0323] In some embodiments, when the first configuration information includes at least the PHR mode information, the above S310 may specifically include:

[0324] In a case where the PHR mode information is used to indicate that configuration information of the PHR corresponding to the first target space parameter is effective, the terminal device reports the PHR corresponding to the first target space parameter among the multiple space parameters; and / or,

[0325] When the PHR mode information is used to indicate that the configuration information of the PHR corresponding to the multiple spatial parameters is effective, the terminal device reports the PHR corresponding to each of the multiple spatial parameters, or the terminal device reports the total PHR corresponding to each of the multiple spatial parameters.

[0326] In some embodiments, the PHR mode information is the RRC parameter twoPHRMode, which is used to indicate that the configuration information of the PHR corresponding to the first target spatial parameter is effective when the RRC parameter twoPHRMode is not configured to be enabled (enable), and is used to indicate that the configuration information of the PHR corresponding to the multiple spatial parameters is effective when the RRC parameter twoPHRMode is configured to be enabled (enable).

[0327] In some embodiments, the first configuration information further includes at least one of the following:

[0328] PHR periodic timer (phr-PeriodicTimer), PHR reporting prohibition timer (phr-ProhibitTimer), PHR transmission power factor change (phr-Tx-PowerFactorChange) or path loss change, PHR mode of the other cell group in dual connectivity (phr-ModeOtherCG), multi-cell PHR or single-cell PHR, maximum permissible exposure (MPE) reporting permission (mpe-Reporting-FR2), power management maximum power reduction (P-MPR) threshold (mpe-Threshold), MPE reporting prohibition timer (mpe-ProhibitTimer).

[0329] Therefore, in the embodiment of the present application, the terminal device can report the PHR corresponding to the spatial parameter information. For example, the terminal device reports the PHR corresponding to the first target spatial parameter among multiple spatial parameters, or reports the PHR corresponding to each of the multiple spatial parameters, or reports the total PHR corresponding to each of the multiple spatial parameters. This enables PHR reporting in multi-panel simultaneous interpretation scenarios.

After multiplexing, S PUCCHs among the M PUCCHs overlap with PUSCHs among the N PUSCHs in the time domain, where M, N, P, and S are all positive integers, and S=MP.
