Currently, there is a possibility that the PUCCH transmitting HARQ-ACK collides with the PUCCH transmitting other uplink control information (Uplink Control Information, UCI), for example, PUCCH resources of HARQ-ACK collide with the PUCCH reported by the scheduling request (Scheduling Request, SR) or channel state information (Channel State Information, CSI). Further, according to the existing multiplexing method, the PUCCH to which UCI is transmitted may collide with the PUCCH of HARQ-ACK transmitted to another TRP.

However, in the related art, in case of transmitting HARQ-ACK to multi-TRP, there is no relevant solution for how to handle collisions between PUCCH resources.

For ease of understanding, some of the details relating to the embodiments of the present invention are described:

1. Multi-TRP transmission technique

The third generation partnership project (3rd Generation Partnership Project,3GPP), release 15, rel-15, proposes a scenario in which multiple reception points/multiple antenna panels (i.e., multi-TRP/multi-Panel) are transmitted, the multi-TRP transmission may increase the reliability and throughput performance of the transmission, e.g., the UE may receive the same data or different data from multiple TRPs. Referring to fig. 1a to 1c, the following multi-TRP transmission scenarios may be specifically included:

1) Multi-antenna panel transmissions within the same TRP;

2) multi-TRP/Panel transmission between multi-TRP, ideal Backhaul (i.e., ideal Backhaul);

3) multi-TRP/panel transmission between multi-TRP, non-ideal Backhaul (i.e., non-ideal Backhaul).

It should be noted that, in the protocol, the TRP provided in the embodiment of the present invention may be explicitly distinguished by configuring the TRP ID, or may be implicitly distinguished by, for example, an associated CSI Report configuration identifier (CSI-Report Config ID), CSI resource configuration identifier (CSI-Resource Config ID), control resource set identifier (CORESET ID), and the like.

2. HARQ-ACK feedback for multi-TRP multi-PDSCH

In the multi-TRP scenario, the multiple TRPs can schedule PDSCH through downlink control information (Downlink control information, DCI) carried by the respective PDCCHs, i.e., multiple DCI schedules multiple PDSCH. At present, the UE is supported to perform HARQ-ACK feedback on PDSCH sent by each TRP in the same time slot in a TDM mode, and respective HARQ-ACK codebooks are adopted.

How to ensure that the PUCCH resources of the feedback HARQ-ACK are allocated in a TDM manner without collision, where a collision may refer to that two PUCCH resources have at least one cyclic prefix orthogonal frequency division multiplexing (Cyclic Prefix Orthogonal Frequency Division Multiplexing, CP-OFDM) or discrete fourier transform Spread orthogonal frequency division multiplexing (Discrete Fourier Transform-Spread OFDM, DFT-S-OFDM) symbol Overlap (i.e. overlay) in the time domain, may include the following ways:

mode 1: the network side divides the PUCCH resources into a plurality of groups which are not overlapped with each other, each TRP configures one group, and the definition and configuration of the PUCCH resource groups are required to be increased;

mode 2: the network side ensures that PUCCH resources used by all TRPs are not overlapped when in configuration, so that the coordination among the TRPs is good, and a PUCCH resource group does not need to be configured and increased;

mode 3: PUCCH resources used by the network side to configure multiple TRPs may overlap.

3. PUCCH collision of SR and HARQ-ACK

The network side includes a PUCCH resource list used by the SR in a PUCCH-Config configured to the terminal through radio resource control (Radio Resource Control, RRC), wherein the PUCCH Format of the SR is PUCCH Format 0 or PUCCH Format 1. And a transmission period (in symbol sym or slot sl) and a slot offset are also configured for the PUCCH resource of each SR, and the candidate PUCCH position for transmitting the SR is determined by the transmission period and slot offset, and when there is an uplink data request, the SR can be transmitted on the nearest candidate PUCCH resource. For example scs=15 kHz, the period selectable values are: sym2, sym7, sl1, sl2, sl4, sl5, sl8, sl10, sl16, sl20, sl40, sl80. For periods sym2, sym7 and sl1, the UE assumes a slot offset of 0, and may configure slot offset values for other periods, e.g., for period sl5, with optional slot offset values of 0,1,2,3,4.

When the PUCCH resource of the SR collides with the PUCCH resource of the HARQ-ACK, the SR is discarded or the SR is multiplexed with the ACK and transmitted on the PUCCH of the HARQ-ACK or the PUCCH of the SR is determined according to the PUCCH format of the SR, whether the SR is a Positive SR (i.e., a Positive SR), and the PUCCH format of the HARQ-ACK.

4. HARQ-ACK and SR collision handling

When the PUCCH resource of the SR collides with the PUCCH resource of the HARQ-ACK, the SR is discarded or the SR is multiplexed with the ACK and transmitted on the PUCCH of the HARQ-ACK or the PUCCH of the SR is determined according to the PUCCH Format of the SR, whether the SR is an affirmative SR, and the PUCCH Format of the HARQ-ACK. The method can be concretely as follows:

if the PUCCH carrying the HARQ-ACK is Format 0, multiplexing and transmitting Positive SR information on the PUCCH resource carrying the HARQ-ACK when at least one Positive SR (namely, positive SR) exists in the PUCCH resources of all the conflicting SRs; when the SRs corresponding to all the conflicted SR resources (i.e. PUCCH resources for carrying SRs) are Negative SRs (i.e. Negative SRs), HARQ-ACKs are sent on the PUCCH of the HARQ-ACKs.

If the PUCCH carrying the HARQ-ACK is Format 1 and the PUCCH carrying the SR is Format 1, when the SRs corresponding to the PUCCH resources of all the conflicting SRs are negative SRs, the HARQ-ACK is sent on the PUCCH carrying the HARQ-ACK; when there is at least one positive SR in all conflicting SR resources, the HARQ-ACK is transmitted on the SR resource of each positive SR.

If the PUCCH carrying HARQ-ACK is Format 1 and the PUCCH carrying SR is Format 0, then HARQ-ACK is sent on the PUCCH carrying HARQ-ACK without sending SR resources (i.e. positive SR is discarded).

And if the PUCCH carrying the HARQ-ACK is Format 2/3/4, transmitting multiplexing information of the HARQ-ACK and the SR state on the PUCCH carrying the HARQ-ACK.

5. HARQ-ACK and CSI collision handling

When the PUCCH resources of the CSI collide with the PUCCH resources of the HARQ-ACK, determining transmission according to the scheduling type:

if the HARQ-ACK is the dynamically scheduled HARQ-ACK, multiplexing the CSI and the HARQ-ACK, and selecting proper PUCCH resources in the PUCCH resource set according to the size of the multiplexed load for transmission;

if the HARQ-ACK is semi-persistently scheduled HARQ-ACK, the CSI is multiplexed with the HARQ-ACK and transmitted on PUCCH resources of the CSI.

6. PUCCH resource determination for transmitting HARQ-ACK

In Rel-15, the network side may configure one or more (up to 4) PUCCH Resource sets (Resource Set) for each UE through RRC signaling, the RRC configuration or predefining a maximum number of bits of UCI payload that each PUCCH Resource Set may carry (for example, the first PUCCH Resource Set is up to 2 bits, the second PUCCH Resource Set, the third PUCCH Resource Set is N1, N2, the fourth PUCCH Resource Set is up to 1706bits, and N1, N2 is configured by RRC), and each PUCCH Resource Set may include multiple PUCCH resources (the first PUCCH Resource Set includes up to 32 PUCCH resources, and the other PUCCH Resource sets each include up to 8 PUCCH resources).

On the UE side, the UE needs to feed back HARQ-ACK after receiving PDSCH, and in order to determine PUCCH resources where feedback HARQ-ACK is located, the UE needs to determine a Slot (i.e. Slot) where PUCCH is located by first scheduling K1 in PDCCH of PDSCH. And then determining the PUCCH resource set where the PUCCH is located according to the bit number of the HARQ-ACK which needs feedback. Within the determined PUCCH resource set, which PUCCH resource within the PUCCH resource set (when the PUCCH resources contained in the PUCCH resource set exceeds 8) is determined specifically according to the PUCCH resource indication (PUCCH Resource Indicator, PRI) field of the PDCCH (when the PUCCH resources contained in the PUCCH resource set does not exceed 8) or the PRI and the PDCCH First control channel element (Control Channel Element, CCE) Index (i.e. First CCE Index). When feeding back HARQ-ACKs of multiple PDSCH transmitted by the same TRP in one slot, the UE determines PUCCH resources according to PRI or PRI in the last DCI scheduling the PDSCH and the first CCE index.

The PUCCH resource is a transmission resource of PUCCH.

Referring to fig. 2, fig. 2 is a block diagram of a network system to which the embodiment of the present invention is applicable, as shown in fig. 2, including a terminal Device 11 and a network side Device 12, where the terminal Device 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, abbreviated as PDA), a mobile internet Device (Mobile Internet Device, MID), or a user side Device such as a web Device (web Device), and it should be noted that the embodiment of the present invention is not limited to a specific type of the terminal Device 11. The network-side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, gNB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN) pico, femto, etc., or the network side device 12 may be an Access Point (AP); the base station may also be a network node composed of a Central Unit (CU) together with a plurality of TRPs that it manages and controls. It should be noted that, in the embodiment of the present invention, the specific type of the network side device 12 is not limited.

In the embodiment of the present invention, the network side device 12 may configure one or more PUCCH resource sets for the terminal device 11, and may indicate to the terminal device 11 transmission resources of N PUCCHs for transmitting second information corresponding to N TRPs, where N is an integer greater than 1, and the second information may include HARQ-ACK.

Specifically, the second information that the transmission resources of the N PUCCHs use for transmitting the N TRPs refers to transmission resources of the N PUCCHs for which an indication (for example, PUCCH for transmitting HARQ-ACK corresponding to PDSCH is dynamically DCI scheduled) or an indication (for example, PUCCH for transmitting HARQ-ACK corresponding to PDSCH of DCI activated Semi-persistent scheduling (Semi-persistent Scheduling, SPS)) is scheduled by a plurality of control resource sets (Control Resource Set, CORESET) associated to the N different TRPs. Wherein, PUCCH resources of a plurality of CORESET scheduling indications or activation indications associated to different TRPs may not collide or may collide. The PUCCH resources scheduled or activated by at least one CORESET associated to the same TRP may or may not collide.

In one embodiment, there may be transmission resources of at most one PUCCH among N PUCCHs indicated by the network-side device 12 that collide in the time domain with transmission resources of the first PUCCH for transmitting the first information. The first information may include SR or CSI.

For example, when the transmission resources of the N PUCCHs do not collide with the transmission resources of the first PUCCH in the time domain, the first information and the N second information may be transmitted on the transmission resources of the respective PUCCHs, and there is no collision between them; in the case that the transmission resource of one target PUCCH collides with the transmission resource of the first PUCCH in the time domain, the terminal device 11 may determine the multiplexing transmission mode according to a preset multiplexing rule (for example, multiple UCI collision handling rules of Rel-15), for example, may determine, according to information such as the PUCCH format of the first information, the PUCCH format of the second information, and the like, to multiplex the second information corresponding to the target PUCCH on the first PUCCH, or multiplex the first information on the target PUCCH, where the transmission resource of the N PUCCHs collides with the transmission resource of the first PUCCH in the time domain. This ensures that there is no collision between the transmissions of the first information and the N second information.

In another embodiment, there may be transmission resources of at least two PUCCHs among N PUCCHs indicated by the network-side device 12 that collide in the time domain with transmission resources of a first PUCCH for transmitting the first information.

In this case, the terminal device 11 may discard the above-described first information directly; the first information may be multiplexed and transmitted on at least one PUCCH among the N PUCCHs, and for example, if it is determined that there is at least one PUCCH that can be multiplexed and transmitted according to a preset multiplexing rule, the first information may be multiplexed and transmitted on some or all PUCCHs among the at least one PUCCH; the transmission resources of the PUCCH used for transmitting some or all of the N pieces of second information may be reselected to ensure that no collision occurs between the transmission of the first information and the N pieces of second information, e.g., the transmission resources of the reselected PUCCH may not collide with the transmission resources of the first PUCCH in the time domain, or at least one PUCCH among the reselected PUCCHs may multiplex the transmission of the first information.

It should be noted that, the preset multiplexing rule may be a rule in the prior art for performing collision processing in a case where a transmission resource of a PUCCH for transmitting the first information collides with a transmission resource of one PUCCH for transmitting the second information in the time domain. Taking the first information as SR and the second information as HARQ-ACK as an example, the preset multiplexing rule may determine to multiplex transmission of HARQ-ACK on the PUCCH for transmitting SR, multiplex transmission of SR on the PUCCH for transmitting HARQ-ACK, or discard SR according to PUCCH format of SR, whether SR is positive SR, PUCCH format of HARQ-ACK, and the like. See for specific details the aforementioned HARQ-ACK and SR collision handling, and HARQ-ACK and CSI collision handling.

Alternatively, in the case where the transmission resources of N PUCCHs indicated by the network side device 12 to the terminal device 11 collide in the time domain, the terminal device 11 may reselect the transmission resources of PUCCHs used for transmitting some or all of the N pieces of second information, and the reselected transmission resources of PUCCHs do not collide in the time domain.

The embodiment of the invention provides a resource processing method which is applied to terminal equipment. Referring to fig. 3, fig. 3 is a flowchart of a resource processing method provided by an embodiment of the present invention, as shown in fig. 3, including the following steps:

step 301, executing resource collision processing in case that transmission resources of a first PUCCH collide with transmission resources of at least two PUCCHs of the N second PUCCHs in a time domain;

In the embodiment of the present invention, the N second PUCCHs may be used to transmit second information corresponding to the N TRPs.

In an embodiment, in a case where the transmission resource of the first PUCCH collides with the transmission resource of at least two PUCCHs of the N second PUCCHs in the time domain, the first information may be multiplexed and transmitted on some or all PUCCHs of the at least one of the N second PUCCHs. Since the transmission resources of the N second PUCCHs do not collide in the time domain, it is ensured that collision does not occur between the multiplexed transmission PUCCH and other PUCCHs transmitting the second information.

For example, whether the first information can be multiplexed and transmitted for each PUCCH that collides with the transmission resource of the first PUCCH may be determined according to the preset multiplexing rule, and if there are a plurality of PUCCHs for multiplexing and transmitting the first information, a part of PUCCHs may be selected from the plurality of PUCCHs for multiplexing and transmitting the first information, or the plurality of PUCCHs may all be multiplexed and transmitted for the first information.

In another embodiment, in case that the transmission resources of the first PUCCH collide with the transmission resources of at least two PUCCHs of the N second PUCCHs in time domain, the transmission resources of the M third PUCCHs may be selected from the configured PUCCH resource set, that is, the transmission resources of PUCCHs used to transmit some or all of the N second information may be reselected, for example, the transmission resources of PUCCHs used to transmit second information corresponding to the collided second PUCCHs may be reselected, so as to ensure that no collision occurs between the first information and the N second information transmissions. For example, there may be at most one PUCCH transmission resource that conflicts with the first PUCCH transmission resource in the time domain, or there may be at least one PUCCH in the reselected PUCCH that multiplexes the first information.

Optionally, the transmission resources of the M third PUCCHs may not collide in the time domain, and the transmission resource of each third PUCCH may meet a loading condition of the corresponding second information, so as to ensure that the corresponding second information may be transmitted. The payload condition that the transmission resource of the third PUCCH may satisfy the corresponding second information may refer to the number of bits that the transmission resource of the third PUCCH may be capable of transmitting the corresponding second information payload, for example, the number of bits that the transmission resource of the third PUCCH may be capable of transmitting the corresponding HARQ-ACK payload.

In another embodiment, in the case that the transmission resource of the first PUCCH collides with the transmission resource of at least two PUCCHs of the N second PUCCHs in the time domain, the first information may be directly discarded, so that transmission of the N second information may be ensured not to collide.

For example, referring to fig. 4, there is a time domain overlap, i.e., a collision, of the transmission resource of PUCCH1 corresponding to transmission HARQ-ACK of TRP1 and the transmission resource of PUCCH2 corresponding to transmission HARQ-ACK of TRP2 with the transmission resource of PUCCH3 corresponding to SR. If it is determined that the SR can be multiplexed and transmitted on PUCCH1 and/or PUCCH2 according to the preset multiplexing rule, the SR can be multiplexed and transmitted on PUCCH1 and/or PUCCH 2. If it is determined that both HARQ-ACK corresponding to TRP1 and HARQ-ACK corresponding to TRP2 need to be multiplexed for transmission on the PUCCH3 according to the preset multiplexing rule, the SR may be discarded or at least one of transmission resources of PUCCH for transmitting HARQ-ACK corresponding to TRP1 and transmission resources of PUCCH for transmitting HARQ-ACK corresponding to TRP2 may be reselected.

In the case where the transmission resources of at least two PUCCHs for transmitting the first information are configured, the transmission resources of the first PUCCH may be any one or each of the transmission resources of the at least two PUCCHs for transmitting the first information.

It should be noted that the uplink transmit beam used by each PUCCH transmitted by a terminal device may be determined by the sounding reference signal resource indication (Sounding Reference Signal resource indicator, SRI) configured or indicated by its associated TRP.

In the embodiment of the invention, when the transmission resources of the first PUCCH used for transmitting the first information collide with the transmission resources of at least two PUCCHs of N second PUCCHs used for transmitting the second information in the time domain, the terminal equipment multiplexes the transmission of the first information on at least one PUCCH of the N second PUCCHs, selects the transmission resources of M third PUCCHs from the configured PUCCH resources, or discards the first information, so that the collision processing is realized under the condition that the collision exists between the PUCCH resources, and the information transmission collision is reduced.

Optionally, multiplexing the first information on at least one PUCCH of the N second PUCCHs may include:

Multiplexing and transmitting the first information on part or all of at least one first target PUCCH if the at least one first target PUCCH exists in the N second PUCCHs;

the first target PUCCH is a PUCCH which is determined according to a preset multiplexing rule and can multiplex and transmit the first information.

In the embodiment of the present invention, when the transmission resource of the first PUCCH collides with the transmission resource of at least two PUCCHs of the N second PUCCHs in the time domain, whether each PUCCH colliding with the first PUCCH can multiplex and transmit the first information may be determined according to the preset multiplexing rule, and when it is determined that at least one first target PUCCH in the PUCCHs colliding with the first PUCCH can multiplex and transmit the first information, the first information may be multiplexed and transmitted on part or all of the at least one first target PUCCH.

For example, the N pieces of second information may include HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3, respectively corresponding to different TRPs, and if the transmission resource of PUCCH1 for transmitting HARQ-ACK1 and the transmission resource of PUCCH2 for transmitting HARQ-ACK2 collide with the transmission resource of PUCCH for transmitting SR1 in the time domain, it is determined according to a preset multiplexing rule that HARQ-ACK1 needs to be multiplexed on the transmission resource of PUCCH of SR1, and SR1 needs to be multiplexed on the transmission resource of PUCCH of HARQ-ACK2, and SR1 is multiplexed on PUCCH2 of HARQ-ACK2 for transmission at this time, and PUCCH1 of HARQ-ACK1 is still transmitted.

The embodiment of the invention multiplexes and transmits the first information on part or all of the at least one first target PUCCH, thereby not only ensuring the transmission of the first information and N second information transmissions, but also ensuring that no conflict occurs between the first information and N second information transmissions and improving the reliability of data transmission.

Optionally, the discarding the first information or selecting transmission resources of M third PUCCHs from the configured PUCCH resource set may include:

and if the second information corresponding to the at least two PUCCHs is determined to be multiplexed and transmitted on the first PUCCH according to a preset multiplexing rule, discarding the first information, or selecting transmission resources of the M third PUCCHs from a configured PUCCH resource set.

In an embodiment, when it is determined according to a preset multiplexing rule that the second information corresponding to the at least two PUCCHs needs to be multiplexed and transmitted on the first PUCCH, the first information may be directly discarded, so that reliable transmission of N second information may be ensured.

For example, the N pieces of second information may include HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3, respectively corresponding to different TRPs, if transmission resources of PUCCH1 for transmitting HARQ-ACK1 and transmission resources of PUCCH2 for transmitting HARQ-ACK2 collide with transmission resources of PUCCH for transmitting SR1 in the time domain, it is determined that HARQ-ACK1 needs to be multiplexed on SR1 according to a preset multiplexing rule, and HARQ-ACK2 also needs to be multiplexed on SR1, at which time SR1 may be directly discarded (i.e., SR1 is not transmitted), and PUCCH1 for transmitting HARQ-ACK1 and PUCCH2 for transmitting HARQ-ACK2 may still be transmitted.

In another embodiment, in a case where it is determined that the second information corresponding to the at least two PUCCHs needs to be multiplexed for transmission on the first PUCCH according to a preset multiplexing rule, transmission resources of the M third PUCCHs may be selected from the configured PUCCH resource set, that is, transmission resources of PUCCHs for transmitting some or all of the N second information may be reselected.

In practical application, when it is determined according to a preset multiplexing rule that the second information corresponding to the at least two PUCCHs needs to be multiplexed and transmitted on the first PUCCH, the transmission resources of the N PUCCHs used for transmitting the N pieces of second information may be reselected, or only the transmission resources of PUCCHs used for transmitting the second information corresponding to some or all PUCCHs in the second PUCCHs where collision occurs may be reselected.

For example, the N pieces of second information may include HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3, respectively corresponding to different TRPs, and if transmission resources of a PUCCH for transmitting HARQ-ACK1 and transmission resources of a PUCCH for transmitting HARQ-ACK2 collide with transmission resources of a PUCCH for transmitting SR1 in the time domain, it is determined that HARQ-ACK1 needs to be multiplexed on SR1 and HARQ-ACK2 also needs to be multiplexed on SR1 according to a preset multiplexing rule, at this time, transmission resources of PUCCHs for transmitting HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3 may be reselected, or only transmission resources of PUCCHs for transmitting HARQ-ACK1 and HARQ-ACK2 may be reselected, or only transmission resources of PUCCHs for transmitting HARQ-ACK1 or HARQ-ACK2 may be reselected.

Optionally, the selecting transmission resources of the M third PUCCHs from the configured PUCCH resource set may include: determining transmission resources of the selected PUCCH according to the PRI instruction in the PUCCH resource set meeting the load condition of the corresponding HARQ-ACK; or when one PRI indicates transmission resources of a plurality of PUCCHs, selecting transmission resources of other PUCCHs indicated by PRI in a PUCCH resource set satisfying a loading condition of a corresponding HARQ-ACK.

Optionally, the M third PUCCHs satisfying the preset condition may include one of:

at most, transmission resources of one PUCCH in the M third PUCCHs collide with transmission resources of the first PUCCH in a time domain, and the transmission resources of the M third PUCCHs do not collide in the time domain;

at least one second target PUCCH exists in the M third PUCCHs, transmission resources of the M third PUCCHs do not collide in a time domain, and the second target PUCCH is a PUCCH which can multiplex and transmit the first information and is determined according to a preset multiplexing rule.

In an embodiment, when the transmission resources of the M third PUCCHs and the transmission resources of the first PUCCH do not collide in the time domain, the first information and the second information may be transmitted on the transmission resources of the respective PUCCHs, and the first information and the second information may not collide with each other. In the case that transmission resources of one PUCCH collide with transmission resources of the first PUCCH in the time domain, whether to multiplex the first information on the target PUCCH or multiplex the second information corresponding to the target PUCCH on the first PUCCH or discard the first information may be determined according to the preset multiplexing rule, where the target PUCCH is a PUCCH where collision occurs in the M third PUCCHs.

Note that, in the case where M is smaller than N, the transmission of the M third PUCCHs may not collide with the transmission resources of the non-reselected PUCCHs in the time domain. For example, the N pieces of second information may include HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3, respectively corresponding to different TRPs, and if only transmission resources of PUCCHs for transmitting HARQ-ACK1 and HARQ-ACK2 are reselected, the reselected transmission resources of PUCCHs for transmitting HARQ-ACK1 and HARQ-ACK2 may also not collide in the time domain with the transmission resources of PUCCHs for transmitting HARQ-ACK 3.

In another embodiment, in the case where there is at least one second target PUCCH that can multiplex the first information among the M third PUCCHs, the first information may be transmitted through partial or complete multiplexing among the at least one second target PUCCH.

Alternatively, in the case that the transmission resource of the first PUCCH collides with the transmission resource of at least two PUCCHs of the N second PUCCHs in the time domain, reselection of the transmission resource of the PUCCH may be performed according to a principle that the number of reselections is minimum. For example, transmission resources of PUCCHs that can satisfy a preset condition and can minimize the number of reselections PUCCHs (i.e., M values) may be selected from the configured resource set.

Alternatively, in the case that the transmission resource of the first PUCCH collides with the transmission resource of at least two PUCCHs of the N second PUCCHs in the time domain, an attempt may be made to select, from the configured PUCCH resource set, the transmission resource of M PUCCHs, in which there is at most one PUCCH that collides with the transmission resource of the first PUCCH in the time domain, and if there is no, the M PUCCH resources in which there is at least one second target PUCCH may be selected from the configured PUCCH resource set.

It should be noted that, the foregoing embodiments may be combined in any combination according to actual needs. For example, in the case where at least one first target PUCCH exists among the N second PUCCHs, the first information may be multiplexed and transmitted on some or all PUCCHs among the at least one first target PUCCHs; and under the condition that the second information corresponding to the at least two PUCCHs are required to be multiplexed and transmitted on the first PUCCH according to a preset multiplexing rule, discarding the first information, or selecting transmission resources of M third PUCCHs from a configured PUCCH resource set, wherein at most transmission resources of one of the M third PUCCHs collide with the transmission resources of the first PUCCH in a time domain, and the transmission resources of the M third PUCCHs do not collide in the time domain, or at least one second target PUCCH exists in the M third PUCCHs, and the transmission resources of the M third PUCCHs do not collide in the time domain, and the second target PUCCH is a PUCCH capable of multiplexing and transmitting the first information according to the preset multiplexing rule.

Optionally, the method may further include:

receiving resource indication information from network side equipment;

the resource indication information is used for indicating transmission resources of N fourth PUCCHs, the fourth PUCCHs are used for transmitting the second information, the transmission resources of at most one PUCCH of the N fourth PUCCHs collide with the transmission resources of the first PUCCH in a time domain, or the transmission resources of at least two PUCCHs of the N fourth PUCCHs collide with the transmission resources of the first PUCCH in a time domain, and the transmission resources of the N second PUCCHs are determined transmission resources according to the transmission resources of the N fourth PUCCHs.

In practical application, the transmission resources of the N fourth PUCCHs transmitting the second information may be scheduled or activated by a plurality of CORESETs associated with different TRPs), and the transmission resources of the PUCCHs scheduled or activated by the plurality of CORESETs associated with different TRPs may not collide or may collide; the transmission resources of at least one CORESET scheduled or activated PUCCH associated to the same TRP may not collide or may collide.

Optionally, in a case where there is no collision between the transmission resources of the N fourth PUCCHs in the time domain, the transmission resources of the N second PUCCHs may be transmission resources of the N fourth PUCCHs.

In this embodiment, when there is no transmission resource of the PUCCH in the N fourth PUCCHs that conflicts with the transmission resource of the first PUCCH in the time domain, the terminal device may transmit on the transmission resource of the PUCCH corresponding to each of the first information and the N second information, where no conflict occurs between the first information and the N second information; in the case that the transmission resource of one PUCCH conflicts with the transmission resource of the first PUCCH in the time domain, the terminal device may determine, according to the preset multiplexing rule, whether to multiplex the first information on the conflicting fourth PUCCH, whether to multiplex the second information corresponding to the conflicting fourth PUCCH on the first PUCCH, or discard the first information.

For example, referring to fig. 5, PUCCH3 of sr1 does not collide with PUCCH1-2 and PUCCH2 at the same time, wherein PUCCH1-2 and PUCCH2 transmit HARQ-ACKs corresponding to different TRPs, respectively. When the SR PUCCH to be transmitted in one slot collides with the HARQ-ACK PUCCH, processing may be performed according to a preset multiplexing rule. When PUCCH1-2 and PUCCH2 need to be transmitted in one slot, and there is a positive SR on SR 2. The multiplexing of the SR2 and the PUCCH2 to the PUCCH2 according to the conflict processing rule is assumed to be transmitted, so that the multiplexed PUCCH2 can be ensured not to conflict with the PUCCH 1-2; or the SR2 and the PUCCH2 are multiplexed on the PUCCH4 of the SR2 according to the collision handling rule, so that the PUCCH4 of the multiplexed SR2 can be ensured not to collide with the PUCCHs 1-2.

It should be noted that, in the case that the transmission resources of at least two PUCCHs exist in the N fourth PUCCHs and collide with the transmission resources of the first PUCCH in the time domain, the terminal device may execute the above resource collision processing, which is not described herein.

Optionally, in the case that the transmission resources of the N fourth PUCCHs have a collision in the time domain, the transmission resources of the N second PUCCHs include S transmission resources of a fifth PUCCH selected by the terminal device from the configured PUCCH resource set, where the S transmission resources of the fifth PUCCHs have no collision in the time domain, and S is a positive integer less than or equal to N.

In the embodiment of the present invention, when there is a collision between the transmission resources of the N fourth PUCCHs in the time domain, the transmission resources of the S fifth PUCCHs may be selected from the configured PUCCH resource set to transmit the second information, that is, the transmission resources of PUCCHs used to transmit some or all of the N second information are reselected, where the transmission resources of the reselected PUCCHs do not collide with each other, and the transmission resources of the reselected PUCCHs are used as the transmission resources of the second PUCCHs.

Optionally, the selecting S transmission resources of the fifth PUCCH from the configured PUCCH resource set may include: determining transmission resources of the selected PUCCH according to the PRI instruction in the PUCCH resource set meeting the load condition of the corresponding HARQ-ACK; or when one PRI indicates transmission resources of a plurality of PUCCHs, selecting transmission resources of other PUCCHs indicated by PRI in a PUCCH resource set satisfying a loading condition of a corresponding HARQ-ACK.

In practical applications, when there is a collision in the time domain of the transmission resources of the N fourth PUCCHs, the transmission resources of the N PUCCHs used for transmitting the N second information may be reselected, or only the transmission resources of PUCCHs used for transmitting the second information corresponding to some or all PUCCHs in the fourth PUCCHs where the collision occurs may be reselected.

For example, the N pieces of second information may include HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3, respectively corresponding to different TRPs, and if transmission resources of a PUCCH for transmitting HARQ-ACK1 and transmission resources of a PUCCH for transmitting HARQ-ACK2 collide in the time domain, transmission resources of PUCCHs for transmitting HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3 may be reselected, transmission resources of PUCCHs for transmitting HARQ-ACK1 and HARQ-ACK2 may be reselected, or transmission resources of PUCCHs for transmitting HARQ-ACK1 or HARQ-ACK2 may be reselected.

Note that, in the case where S is smaller than N, the transmission of the S third PUCCHs may not collide with the transmission resources of the non-reselected PUCCHs in the time domain. For example, the N pieces of second information may include HARQ-ACK1, HARQ-ACK2, and HARQ-ACK3, respectively corresponding to different TRPs, and if only transmission resources of PUCCHs for transmitting HARQ-ACK1 and HARQ-ACK2 are reselected, the reselected transmission resources of PUCCHs for transmitting HARQ-ACK1 and HARQ-ACK2 may also not collide in the time domain with the transmission resources of PUCCHs for transmitting HARQ-ACK 3.

In the embodiment of the present invention, when transmission resources of the N fourth PUCCHs collide in the time domain, the terminal device may reselect transmission resources of PUCCHs used for transmitting some or all of the N second information, that is, transmission resources of the S fifth PUCCHs, and the reselected transmission resources of PUCCHs do not collide, so that a situation that collisions occur between multiple second information transmissions may be reduced.

Optionally, the transmission resource of each PUCCH in the transmission resources of the S fifth PUCCHs meets a loading condition of the corresponding second information.

In the embodiment of the present invention, the transmission resource of each PUCCH in the S fifth PUCCH transmission resources satisfies the load condition of the second information corresponding to the transmission resource, that is, the transmission resource of each PUCCH in the S fifth PUCCH transmission resources may carry the load of the second information corresponding to the transmission resource of the second PUCCH, so as to ensure complete transmission of the second information. The transmission resource of the PUCCH satisfying the payload condition of the corresponding second information may refer to the number of bits that the transmission resource of the PUCCH can transmit the corresponding second information payload. For example, the transmission resource of the PUCCH can transmit the number of bits of its corresponding HARQ-ACK payload.

For example, referring to fig. 6, the network side configures 4 PUCCH resources for transmitting HARQ-ACKs for the terminal device, and assumes PUCCH indicated by the last PRI before feedback HARQ-ACKs of the CORESET scheduled PDSCH associated with TRP1 as PUCCH2, and PUCCH indicated by the last PRI before feedback HARQ-ACKs of the CORESET scheduled PDSCH associated with TRP2 as PUCCH3. If the terminal device detects that the PUCCH2 collides with the PUCCH3, the terminal device selects two non-conflicting PUCCH resources and satisfies the minimum PUCCH resource for feeding back two HARQ-ACK loading conditions, for example, PUCCH2 and PUCCH4, and transmits HARQ-ACK respectively. The two TRPs may each blindly check the HARQ-ACK on the possible candidate PUCCH resources.

In practical application, when there is a conflict in the time domain of the transmission resources of the N fourth PUCCHs, it may first attempt to select, from the configured set of PUCCH resources, S transmission resources of PUCCHs that do not conflict in the time domain and satisfy the loading condition of the corresponding second information, and if there is no, S transmission resources of PUCCHs that do not conflict in the time domain and satisfy the loading condition of the corresponding second information, and for the transmission resources of PUCCHs that do not satisfy the loading condition of the corresponding second information, the loading of the corresponding second information may be reduced.

Optionally, the method may further include:

reducing the load of the second information corresponding to the third target PUCCH under the condition that the transmission resource of the third target PUCCH does not meet the load condition of the second information corresponding to the transmission resource; wherein the third target PUCCH is a PUCCH of the N second PUCCHs.

In the embodiment of the present invention, the third target PUCCH may be any PUCCH of the N second PUCCHs. Specifically, in the case that the transmission resource of the third target PUCCH does not meet the load condition of the corresponding second information, the load of the corresponding second information may be reduced, so that the second target PUCCH may carry the second information corresponding thereto.

Optionally, the second information includes HARQ-ACK; the reducing the load of the second information corresponding to the third target PUCCH may include one of:

if the code block group CBG is configured to transmit the physical downlink shared channel PDSCH, the HARQ-ACK of the CBG is converted into the HARQ-ACK of a transmission block TB;

if the spatially bonded HARQ-ACK PUCCH is not configured and at most two coded code words CW are configured, the HARQ-ACK of at least two CWs is converted to a TB-bonded HARQ-ACK.

In the embodiment of the invention, under the condition that the network side equipment configures the terminal equipment with the PDSCH transmitted through a Code Block Group (CBG), the terminal equipment can convert the HARQ-ACK of the CBG into the HARQ-ACK of the TB, namely, the HARQ-ACK bit of the CBG level is converted into the HARQ-ACK bit of the TB level, so as to reduce the HARQ-ACK load.

In the case where the network side device does not configure a spatially bundled HARQ-ACK PUCCH (i.e., HARQ-acksfatialbundling PUCCH) for the terminal device and configures DCI to schedule at most two encoded CodeWords (CWs) (i.e., maxnrofcodewordsschedule bydci is configured to 2), the terminal device may convert HARQ-ACK bits of the plurality of encoded CodeWords into HARQ-ACK bits of TB Bundling (i.e., TB Bundling) to reduce HARQ-ACK load.

In summary, the resource processing method provided by the embodiment of the invention can ensure that PUCCH sent by the terminal equipment is not overlapped after the SR and the HARQ-ACK collide, and provides a solution for the conflict of the PUCCH of the HARQ-ACK and a solution for the incapability of placing complete HARQ-ACK load by the PUCCH.
