Description

[0001] Cross - reference to related applications

[0002] This application is a divisional application of the Chinese patent application with the application number 201910894530.8 and the application title "Resource Determination Method and Device", which was filed with the Chinese Patent Office on September 20, 2019. Technical Field

[0003] This application relates to the field of communication technologies, and in particular, to a resource determination method and device. Background Art

[0004] In the fifth-generation (5G) new radio (NR) system, in the Release 15 (Rel-15) phase, only one physical uplink control channel (PUCCH) for transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) message is supported in one slot. The higher-layer signaling configures 1 to 4 PUCCH resource sets. Different PUCCH resource sets correspond to different numbers of transmission bits. Each PUCCH resource set contains multiple PUCCH resources. Among them, the first PUCCH resource set is used to carry no more than 2-bit uplink control information (UCI) transmission, the second PUCCH resource set is used to carry 3 to N1-bit UCI transmission, the third PUCCH resource set is used to carry N1 + 1 to N2-bit UCI transmission, and the fourth PUCCH resource set is used to carry N2 + 1 to 1706, where N1 and N2 are configured by the higher-layer signaling. If no more than 2 sets are configured, N1 does not need to be configured. When 2 sets are configured, N1 is fixed at 1706. If no more than 3 sets are configured, N2 does not need to be configured. When 3 sets are configured, N2 is fixed at 1706. The first PUCCH resource set may contain at most 32 PUCCH resources, and the remaining PUCCH resource sets contain at most 8 PUCCH resources.

[0005] In Rel-15, when HARQ-ACK is transmitted on PUCCH, first, according to the number of HARQ-ACK bits to be transmitted, a corresponding PUCCH resource set is selected; then, in the selected PUCCH resource set, according to the physical downlink shared channel (PDSCH) or semi-persistent scheduling (SPS) PDSCH release corresponding to the PUCCH resource indication field in the corresponding PDCCH that needs to transmit HARQ-ACK on PUCCH, one of the PUCCH resources is determined, and HARQ-ACK is transmitted on the determined PUCCH resource. If there are other UCIs, such as scheduling request (SR) and / or channel state information (CSI) transmitted simultaneously with HARQ-ACK, the number of UCI bits for determining the PUCCH resource set in the above process is the total number of UCI bits of all multiplexed transmissions. Since there is only one PUCCH carrying HARQ-ACK in one time slot, therefore, the above PUCCH resource configuration and indication are all carried out for one time slot, that is, one determined PUCCH resource can be on any one or more symbols in the time slot where PUCCH transmission is located.

[0006] In Rel-16, to support faster HARQ-ACK feedback, it is supported to transmit multiple PUCCHs carrying HARQ-ACK with non-overlapping time-domain resources within one time slot (slot). One slot is divided into multiple sub-slots, and PUCCH can be transmitted in each sub-slot. Among them, the number of sub-slots into which one slot can be divided is variable, for example, configured by higher-layer signaling, etc. For example, one slot (14 symbols) can be divided into two sub-slots, then the symbol length of each sub-slot is 7; for another example, one slot can be divided into 4 sub-slots, then it can be that the symbol length of two sub-slots is 3 and the symbol length of two sub-slots is 4; for another example, one slot can be divided into 7 sub-slots, then the symbol length of each sub-slot is 2.

[0007] In the Rel-16 phase, to obtain spatial transmission gain, multiple TRP transmissions are supported, that is, the terminal can communicate with multiple transmission and reception points (TRPs), and the beams used by different TRPs may be different. The PDSCH or SPS PDSCH release from different TRPs may perform HARQ-ACK feedback on the same PUCCH, or may also perform feedback on an independent PUCCH. That is, the PDSCH or SPS PDSCH release from TRP1 is transmitted on the PUCCH corresponding to TRP1, and the PDSCH or SPS PDSCH release from TRP2 is transmitted on the PUCCH corresponding to TRP2. At this time, different TRPs require different PUCCH resources.

[0008] In summary, in Rel-16, when supporting the transmission of multiple PUCCHs carrying HARQ-ACK in a sub-slot manner within a time slot, there is no solution for how to configure PUCCH resources; when supporting multiple TRPs (Transmission Reception Points), there is also no clear solution for how to configure PUCCH resources for different TRPs. Summary of the Invention

[0009] Embodiments of this application provide a resource determination method and apparatus to enable the terminal to configure PUCCH resources for different TRPs or different sub-slots when there are multiple TRPs or multiple sub-slots.

[0013] By only configuring the PUCCH resource set shared by all sub-slots or all TRPs and combining the numbers of sub-slots or TRPs, this method realizes the differentiation of PUCCH resources corresponding to different sub-slots or TRPs in the same PUCCH resource set, thereby ensuring that, without modifying the PUCCH resource configuration, when the terminal has multiple TRPs or multiple sub-slots, the PUCCH resources for different TRPs or different sub-slots can be configured.

[0151] The following describes each embodiment of the present application in detail with reference to the accompanying drawings of the specification. It should be noted that the display order of the embodiments of the present application only represents the sequence of the embodiments, and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0152] In the embodiments of the present application, at least one PUCCH resource set is configured by configuring signaling (such as high-layer signaling). Each PUCCH resource set contains M PUCCH resources. The M resources in each PUCCH resource set are further divided into N subsets. Each subset corresponds to a sub-slot in a time slot or corresponds to a TRP, where N is the number of sub-slots in a time slot or N is the number of TRPs. That is to say, a subset corresponds to providing PUCCH resources for transmitting PUCCH in a sub-slot, or a subset corresponds to providing PUCCH resources for PUCCH transmission corresponding to a TRP. Both M and N are integers greater than or equal to 1. Among them, the number of TRPs is the number of TRPs corresponding to a UE, which may be of the same cell / carrier or of different cells / carriers. For example, in the case of carrier aggregation, carrier 1 corresponds to TRP1 (that is, the terminal can communicate between carrier 1 and TRP1, such as sending an uplink transmission to TRP1, or receiving a downlink transmission sent by TRP1, and the same applies hereinafter and will not be elaborated), carrier 2 corresponds to TRP2, or carrier 1 can correspond to both TRP1 and TRP2 at the same time, and carrier 2 can correspond to both TRP1 and TRP2 at the same time.

[0153] The following introduces the technical solutions provided in the embodiments of the present application from the terminal side and the network side respectively.

[0154] Terminal-side behavior:

[0155] See Figure 1 , a resource determination method provided in the embodiments of the present application includes:

[0156] S101. Receive the configuration signaling sent by the network side, and obtain the PUCCH resource set based on the configuration signaling;

[0157] Optionally, the configuration signaling is high-layer signaling or signaling carried by PDCCH;

[0158] Optionally, the PUCCH resource set includes one or more resource sets;

[0159] Optionally, the PUCCH resource set is shared for multiple sub-slots in a time slot;

[0160] Optionally, the PUCCH resource set is shared for multiple TRPs corresponding to the terminal.

[0161] S102. Determine the target PUCCH resource set, and determine a PUCCH resource in the target PUCCH resource set according to the PUCCH resource indication field (this indication field is carried in the DCI used by the PDCCH corresponding to the PUCCH) and the target number corresponding to the PUCCH.

[0162] Among them, determining the target PUCCH resource set, for example, includes: determining, according to the number of bits of UCI transmitted on the PUCCH, that the PUCCH resource set corresponding to the number of bits in the obtained PUCCH resource set is the target PUCCH resource set.

[0163] The target is the sub-slot where the PUCCH transmission is located (for example, determined according to the K0 value indicated by the feedback timing indication field in the PDCCH corresponding to the PUCCH, or a feedback timing K0 value configured by the higher layer), or the TRP corresponding to the PUCCH (for example, it can be determined which TRP the PUCCH transmission corresponds to according to the beam used by the PUCCH, or it can be determined which TRP the PUCCH corresponds to according to the CORESET where the PDCCH corresponding to the PUCCH is transmitted. There is a corresponding relationship between the CORESET and the TRP. For example, if the PDCCH corresponding to the PUCCH is transmitted in CORESET1, then the PUCCH corresponds to TRP1, where CORESET1 corresponds to TRP1).

[0164] In the embodiments of the present application, determining a PUCCH resource in the target PUCCH resource set according to the PUCCH resource indication field and the target number corresponding to the PUCCH includes multiple methods, for example:

[0165] Method 1-1: When the target corresponding to the PUCCH is the sub-slot where the PUCCH transmission is located: Divide the M PUCCH resources in the target PUCCH resource set into N sub-sets, each sub-set corresponding to a sub-slot in a time slot, where N is the number of sub-slots included in a time slot; According to the number of the sub-slot where the PUCCH transmission is located, determine the sub-set corresponding to the sub-slot in the target PUCCH resource set, and according to the PUCCH resource indication field, determine a PUCCH resource in the determined sub-set, where the PUCCH resource indication field indicates the number of the PUCCH resource in a sub-set (this number is the number of the PUCCH resource in the sub-set, rather than the number in the target PUCCH resource set. That is, if the PUCCH resource is the first resource in the sub-set, its number is 0, regardless of which resource the PUCCH resource is in the target PUCCH resource set, and so on; The following similar situations are the same as the description here and will not be repeated).

[0166] Method 1-2: When the target corresponding to the PUCCH is the TRP corresponding to the PUCCH: Divide the M PUCCH resources in the target PUCCH resource set into N subsets, each subset corresponding to one of the multiple TRPs, where N is the number of TRPs corresponding to the terminal; Determine the subset corresponding to the TRP with the number in the target PUCCH resource set according to the number of the TRP corresponding to the PUCCH, and determine a PUCCH resource in the determined subset according to the PUCCH resource indication field, where the PUCCH resource indication field indicates the number of the PUCCH resource in a subset.

[0167] In the above Method 1-1 and Method 1-2, dividing the M PUCCH resources in the target PUCCH resource set into N subsets specifically includes, for example, one of the following methods:

[0168] Method 1: Divide the M PUCCH resources included in the target PUCCH resource set into N equal subsets, where M is an integer multiple of N;

[0169] Method 2: The first or the last subset contains PUCCH resources, and the remaining subsets contain PUCCH resources (this method can be applied whether M is or is not an integer multiple of N);

[0170] Method 3: The first M mod N or the last M mod N subsets contain PUCCH resources, and the remaining subsets contain PUCCH resources (this method can be applied whether M is or is not an integer multiple of N).

[0171] Optionally, for the above Methods 1 to 3, each subset is divided in the order of the numbers of the PUCCH resources included in the target PUCCH resource set, and the N subsets correspond to the N TRPs or the N sub-slots in a time slot in order. That is, assuming that each subset contains M / N PUCCH resources, the first subset is the first M / N (for example, the 1st resource to the M / Nth resource) PUCCH resources in the target PUCCH resource set, corresponding to the first of the N TRPs or N sub-slots, the second subset is the (M / N + 1)th to the 2*(M / N)th PUCCH resources in the target PUCCH resource set, corresponding to the second of the N TRPs or N sub-slots, and so on.

[0172] Method 2: Determine P consecutive PUCCH resources in the target PUCCH resource set according to the PUCCH resource indication field, where one state of the PUCCH resource indication field corresponds to or or a PUCCH resource, and determine a PUCCH resource from the P PUCCH resources according to the number of the target corresponding to the PUCCH.

[0173] Optionally:

[0174] If P > N, it is necessary to further determine a PUCCH resource from the P PUCCH resources according to the CCE (Control Channel Element) number of the PDCCH that provides the PUCCH resource indication field, that is, each number in the numbers of the targets corresponding to the PUCCH can correspond to multiple PUCCH resources, and which one to specifically select is further determined according to the CCE number;

[0175] If P = N, each number in the numbers of the targets corresponding to the PUCCH corresponds to one PUCCH resource among the P PUCCH resources, and a PUCCH resource corresponding to a target number can be determined according to the one-to-one relationship;

[0176] If P < N, the target numbers corresponding to multiple PUCCHs need to correspond to the same PUCCH resource among the P PUCCH resources, and the correspondence between the target number and one PUCCH resource among the P PUCCH resources can be determined according to the target number and the total number;

[0177] Specifically, for example, the PUCCH resource number (for example, in the target PUCCH resource set, the PUCCH resources are numbered continuously from 0) of the PUCCH resource (that is, the finally determined PUCCH resource, that is, the PUCCH resource for sending the PUCCH) in the target PUCCH resource set can be calculated according to one of the following formulas 1 to 4, where r PUCCH is the number of the PUCCH resource in the target PUCCH resource set, 0 ≤ r PUCCH ≤ R PUCCH -1, R PUCCH is the number of PUCCH resources included in the target PUCCH resource set, Δ PRI is the value of the PUCCH resource indication field, and the value range is 0 to K - 1, K is a predetermined positive integer value (for example, it can be 8) or a value related to the number of bits of the PUCCH resource indication field (for example, specifically the number of combined states corresponding to the number of bits of the PUCCH resource indication field, for example, when it is an A-bit PUCCH resource indication field, K = 2 A); Among them, it is assumed in Formulas 1 to 3 that P does not exceed N. Therefore, the PUCCH resource for PUCCH transmission can be directly determined according to the PUCCH resource indication field and the corresponding target number of the PUCCH, without further determining the PUCCH resource according to the CCE. Formula 4 gives different formulas for P not exceeding N and P exceeding N. Of course, the formula involving CCE in Formula 4 can also be applied to the case where P does not exceed N, that is, the formula in Formula 4 without CCE information is actually simplified based on the formula with CCE information. Therefore, Formula 4 can also be changed to when Δ PRI < R PUCCH mod K, the first formula in Formula 4 is always used, regardless of or When Δ PRI ≥ R PUCCH mod K, the third formula in Formula 4 is always used, regardless of or In the following formulas, if there is always a multiple relationship between R PUCCH and K, the ceiling PUCCH and floor operations related to the operation of R and K as well as the R PUCCH mod K operation (A mod B is a modulo operation, that is, the remainder obtained by dividing A by B) can be removed, and there is no need to divide into different formulas according to the relationship between Δ PR and R PUCCH mod K. It is always calculated according to the formula of Δ PRI ≥ R PUCCH mod K;

[0189] When Δ PRI ≥ R PUCCH mod K and when:

[0190]

[0191] When Δ PRI ≥ R PUCCH mod K and when:

[0192]

[0193] Wherein, optionally:

[0194] When the target corresponding to the PUCCH is the sub - slot where the PUCCH transmission is located: n index is the number of the sub - slot in a time slot, and the value range is 0 to N - 1, where N is the number of sub - slots in a time slot;

[0195] When the target corresponding to the PUCCH is the TRP corresponding to the PUCCH: n index is the number of each TRP among the N TRPs corresponding to the terminal, and the value range is 0 to N - 1, where N is the number of TRPs corresponding to the terminal;

[0196] In one case, R PUCCH is an integer multiple of K, that is, the target PUCCH resource set always contains an integer multiple of K resources, so as to ensure that each Δ PRI state always corresponds to the same number of resources. However, if the number of resources corresponding to each Δ PRI state is less than N, it means that some sub - slots among the N sub - slots need to correspond to the same resource, and some sub - slots correspond to independent resources;

[0197] In another case, R PUCCH = K * N, that is, the target PUCCH resource set always contains K * N resources, so as to ensure that one Δ PRI state always corresponds to N resources, and each of the N resources corresponds to one sub - slot among the N sub - slots;

[0198] In another case, if the number of R PUCCH is not restricted, the above - mentioned situation may occur, or different Δ PRIThe number of resources corresponding to the status is different, so when determining the PUCCH resources in a sub-slot, different Δs are used. PRI When indicating resources by status, the correspondence between the sub-slot and the resources is different.

[0199] Method 3: Determine T PUCCH resources according to the number of the target corresponding to the PUCCH. The T PUCCH resources correspond to K statuses of the PUCCH resource indication field. Or Or Determine a PUCCH resource among the T PUCCH resources according to the PUCCH resource indication field.

[0200] Optionally, among them:

[0201] If T>K, it is necessary to further determine a PUCCH resource among the T PUCCH resources according to the CCE number of the PDCCH providing the PUCCH resource indication field, that is, each number in the number of the target corresponding to the PUCCH can correspond to multiple PUCCH resources, and which one to specifically select is further determined according to the CCE number.

[0202] If T = K, the status indicated by each PUCCH resource corresponds to one PUCCH resource among the T PUCCH resources, and a PUCCH resource can be determined according to the one-to-one relationship.

[0203] If T<K, some of the K statuses in the PUCCH resource indication field are idle, and T of the K statuses respectively correspond to one of the T resources, and a PUCCH resource can be determined according to the one-to-one relationship.

[0204] Specifically, for example, the PUCCH resource number in the target PUCCH resource set can be calculated according to one of the following formulas. Among them, r PUCCH is the PUCCH resource number in the target PUCCH resource set, 0≤r PUCCH ≤R PUCCH -1, R PUCCH is the number of PUCCH resources included in the target PUCCH resource set, Δ PRI is the value of the PUCCH resource indication field, and the value range is 0 to K-1. K is a predetermined positive integer value (for example, it can be 8) or a value related to the number of bits of the PUCCH resource indication field (for example, specifically the number of combined states corresponding to the number of bits of the PUCCH resource indication field. For example, when the PUCCH resource indication field is A bits, K = 2 A )), n indexThe specific description is the same as the above Method 2. Among them, in both Formula 5 and Formula 6, it is assumed that T does not exceed K. Therefore, the PUCCH resource for PUCCH transmission can be directly determined according to the PUCCH resource indication field and the corresponding target number of the PUCCH, without further determining the PUCCH resource according to the CCE. Formula 7 is for different formulas given when T (i.e., and ) does not exceed K and when T exceeds K. Of course, the formula in Formula 7 that involves the CCE can also be applied to the case where T does not exceed K. That is, the formula in Formula 7 that does not contain CCE information is actually simplified based on the formula that contains CCE information. Therefore, Formula 7 can also be changed to: when n index <R PUCCH mod N, the first formula in Formula 7 is always used, regardless of or When n index ≥R PUCCH mod N, the third formula in Formula 7 is always used, regardless of or In the following formulas, if there is always a multiple relationship between R PUCCH and N, then the ceiling PUCCH and floor operations related to the operation of R and N, as well as the R PUCCH mod N operation, can be removed. There is no need to divide into different formulas according to the relationship between n index and R PUCCH mod N. It is always calculated according to the formula of n index ≥R PUCCH mod N;

[0205] Formula 5 (assuming R PUCCH = K * N, the value of a PUCCH resource indication field corresponds to N resources, and each PUCCH resource corresponds to a target number):

[0277] Several specific embodiments are given below for illustration.

[0278] Embodiment 1 (corresponding to the above Method 1-1): Assume that the determined target PUCCH resource set contains M = 16 resources, and a time slot contains N = 2 sub-slots. Then the first sub-slot corresponds to the 1st to 8th resources among the 16 resources, and the second sub-slot corresponds to the 9th to 16th resources among the 16 resources. The 3-bit PUCCH resource indication field can indicate numbers 0 to 7, respectively corresponding to 8 resources in the subset corresponding to each sub-slot, as shown in Table 1. For example, if it is determined that the PUCCH is transmitted in the second sub-slot, then:

[0279] Base station side: According to the fact that the sub-slot corresponding to the PUCCH is the second sub-slot, determine a PUCCH resource for transmitting the PUCCH in the second sub-slot from the 8 PUCCH resources corresponding to the second sub-slot in the target PUCCH resource set (i.e., the 9th to 16th resources in the target PUCCH resource set), and generate a PUCCH resource indication field corresponding to the determined PUCCH resource. For example, if it is determined to be the 1st PUCCH resource in the subset corresponding to the second sub-slot (i.e., the 9th PUCCH resource in the target PUCCH resource set), then the base station generates "000" as the PUCCH resource indication and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal in the second sub-slot according to the above determined PUCCH resource;

[0280] On the terminal side: Receive the PDCCH corresponding to the PUCCH, and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resources according to the PUCCH resource indication carried in the last PDCCH). According to the sub-slot corresponding to the PUCCH being the second sub-slot, among the 8 PUCCH resources corresponding to the second sub-slot in the target PUCCH resource set, if it is determined that the PUCCH resource indication field indicates one of these 8 resources, and according to the PUCCH resource indication field indicating "000", then determine to use the first PUCCH resource in the subset corresponding to the second sub-slot to transmit the PUCCH, that is, use the 9th PUCCH resource in the target PUCCH resource set for PUCCH transmission.

[0284] Embodiment 2 (corresponding to the above Method 1-2): Assume that the determined target PUCCH resource set contains M = 16 resources, and the terminal corresponds to N = 2 TRPs. Then the first TRP corresponds to the 1st to 8th resources among the 16 resources, and the second TRP corresponds to the 9th to 16th resources among the 16 resources. The 3-bit PUCCH resource indication field can indicate numbers 0 to 7, respectively corresponding to the 8 resources in the subset corresponding to each TRP, as shown in Table 2. For example, if it is determined that the PUCCH corresponds to the second TRP for transmission, then:

[0285] On the base station side: According to the TRP corresponding to the PUCCH being the second TRP, determine a PUCCH resource from the 8 PUCCH resources corresponding to the second TRP in the target PUCCH resource set (i.e., the 9th to 16th resources in the target PUCCH resource set) for transmitting the PUCCH corresponding to the second TRP, and generate a PUCCH resource indication field corresponding to the determined PUCCH resource. For example, if it is determined to be the first PUCCH resource in the subset corresponding to the second TRP (i.e., the 9th PUCCH resource in the target PUCCH resource set), then the base station generates "000" as the PUCCH resource indication and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal corresponding to the second TRP according to the determined PUCCH resource;

[0286] Terminal side: Receive the PDCCH corresponding to the PUCCH, and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resources according to the PUCCH resource indication carried in the last PDCCH). According to the fact that the TRP corresponding to the PUCCH is the second TRP, among the 8 PUCCH resources corresponding to the second TRP in the target PUCCH resource set, if it is determined that the PUCCH resource indication field indicates one of these 8 resources, and then according to the PUCCH resource indication field indicating "000", the first PUCCH resource in the subset corresponding to the second TRP is determined to transmit the PUCCH corresponding to the second TRP, that is, the 9th PUCCH resource in the target PUCCH resource set is used for PUCCH transmission.

[0287] Table 2:

[0288]

[0289]

[0290] In Embodiment 1 and Embodiment 2, when assuming that the PUCCH resource indication field (PRI, PUCCH resource indicator) is a 3-bit indication field, if the number of PUCCH resources included in a subset after grouping is less than 8 (i.e., the number of indication states of the 3-bit PRI), then some states of the PRI are idle. If the number of PUCCH resources included in a subset after grouping exceeds 8, the CCE number of the PDCCH containing the PRI can be further combined to determine the PUCCH resources (that is, one PRI state corresponds to multiple PUCCH resources, and which PUCCH resource to select can be implicitly determined according to the CCE number of the PDCCH).

[0291] Embodiment 3 (corresponding to Method 2): Assume that the determined target PUCCH resource set contains R PUCCH = 16 resources, one time slot contains N = 2 sub-time slots, n index is the number of the sub-time slot in a time slot, and the value range is 0 to N - 1. The PUCCH resource indication field contains 3-bit indication information and can indicate K = 8 states. The 3-bit PUCCH resource indication field can indicate numbers from 0 to 7. Then, according to the formula the indication relationship shown in Table 3 can be obtained. For example, when it is determined that the PUCCH is transmitted in the second sub-time slot, that is, n index = 1, then:

[0292] Base station side: According to the above formula, it can be determined that in the target PUCCH resource set, consecutive One PUCCH resource corresponds to one PRI indication value (i.e., Δ PRI value), as shown in Table 3. Thus, K PUCCH resources corresponding to each sub-slot can be obtained. For example, for the first sub-slot, it corresponds to the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, and 15th PUCCH resources in the target PUCCH resource set. For the second sub-slot, it corresponds to the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, and 16th PUCCH resources in the target PUCCH resource set. The base station determines one PUCCH resource from the 8 PUCCH resources corresponding to the second sub-slot for transmitting the PUCCH in the second sub-slot. For example, it is determined as the 2nd PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource with resource number r PUCCH =1. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "000" and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal according to the determined PUCCH resource in the second sub-slot;

[0293] Terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI =0) and the sub-slot number n index =1 of the PUCCH, r PUCCH =1 can be calculated according to the formula, which means using the 2nd PUCCH resource in the target PUCCH resource set for PUCCH transmission;

[0294] Another example, when it is determined that the PUCCH is transmitted in the first sub-slot, that is, n index =0, then:

[0295] Base station side: According to the above formula, it can be determined that in the target PUCCH resource set, consecutive PUCCH resources correspond to one PRI indication value (i.e., Δ PRIvalue), as shown in Table 3, so that K PUCCH resources corresponding to each sub - slot can be obtained. For example, for the first sub - slot, it corresponds to the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, and 15th PUCCH resources in the target PUCCH resource set. For the second sub - slot, it corresponds to the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, and 16th PUCCH resources in the target PUCCH resource set. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the second sub - slot for transmitting the PUCCH in the second sub - slot. For example, it is determined as the 2nd PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource number r PUCCH = 1 of the PUCCH resource, then the base station generates a PRI indication field corresponding to this PUCCH resource as "000", and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal in the second sub - slot according to the determined PUCCH resource as above;

[0296] Terminal side: Receive the PDCCH corresponding to the PUCCH, and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI = 0) and the sub - slot number n index = 1 of the PUCCH, the value of r can be calculated according to the formula PUCCH = 1, which means using the 2nd PUCCH resource in the target PUCCH resource set for PUCCH transmission;

[0297] For another example, when it is determined that the PUCCH is transmitted in the first sub - slot, that is, n index = 0, then:

[0298] Base station side: Determine 8 PUCCH resources corresponding to each sub - slot in the same way as above. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the first sub - slot for transmitting the PUCCH in the first sub - slot. For example, it is determined as the 7th PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource number r PUCCH = 6 of the PUCCH resource, then the base station generates a PRI indication field corresponding to this PUCCH resource as "011", and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal in the first sub - slot according to the determined PUCCH resource as above;

[0299] Terminal side: Receive the PDCCH corresponding to the PUCCH, and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resources according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "011" (i.e., Δ PRI = 3) and the sub-slot number n index = 0 of the PUCCH, r PUCCH = 6 can be calculated according to the formula, which means using the 7th PUCCH resource in the target PUCCH resource set for PUCCH transmission.

[0303] Example 4 (corresponding to Method 2): Assume that the determined target PUCCH resource set contains R PUCCH = 16 resources, the terminal corresponds to N = 2 TRPs, n index is the number of the TRP corresponding to the terminal, and the value range is 0 to N - 1. The PUCCH resource indication field contains 3-bit indication information and can indicate K = 8 states. The 3-bit PUCCH resource indication field can indicate numbers 0 to 7. Then, according to the formula the indication relationship shown in Table 3 can also be obtained (take

[0304] Base station side: According to the above formula, it can be determined that in the target PUCCH resource set, consecutive PUCCH resources correspond to a PRI indication value (i.e., Δ PRI value), as shown in Table 3. Thus, K PUCCH resources corresponding to each TRP can be obtained. For example, for the first TRP, it corresponds to the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, and 15th PUCCH resources in the target PUCCH resource set. For the second TRP, it corresponds to the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, and 16th PUCCH resources in the target PUCCH resource set. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the second TRP for transmitting the PUCCH corresponding to the second TRP. For example, it is determined to be the 2nd PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource number r PUCCHFor the PUCCH resource with r = 1, the base station generates a PRI indication field corresponding to this PUCCH resource as "000", and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal corresponding to the second TRP according to the determined PUCCH resource above.

[0305] Terminal side: Receive the PDCCH corresponding to the PUCCH, and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI = 0) and the TRP number n index = 1 of the PUCCH, r can be calculated according to the formula PUCCH = 1, which means using the second PUCCH resource in the target PUCCH resource set to transmit the PUCCH corresponding to the second TRP.

[0306] For another example, when it is determined that the PUCCH corresponds to the first TRP, i.e., n index = 0, then:

[0307] Base station side: Determine 8 PUCCH resources corresponding to each TRP in the same way as above. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the first TRP to transmit the PUCCH corresponding to the first TRP. For example, it is determined as the 7th PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource number r PUCCH = 6 of the PUCCH resource. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "011", and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal corresponding to the first TRP according to the determined PUCCH resource above.

[0308] Terminal side: Receive the PDCCH corresponding to the PUCCH, and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "011" (i.e., Δ PRI = 3) and the TRP number n index = 0 of the PUCCH, r can be calculated according to the formula PUCCH = 6, which means using the 7th PUCCH resource in the target PUCCH resource set to perform the PUCCH transmission corresponding to the first TRP.

[0309] Embodiment 5 (corresponding to Method 3): Assume that the determined target PUCCH resource set contains R PUCCH = 16 (i.e., R PUCCH = N * K) resources, one time slot contains N = 2 sub - time slots, n index is the number of the sub - time slot in a time slot, and its value range is 0 to N - 1. The PUCCH resource indication field contains 3 - bit indication information, which can indicate K = 8 states. The 3 - bit PUCCH resource indication field can indicate numbers from 0 to 7. Then, according to the formula r PUCCH = n index ·K + Δ PRI the indication relationship shown in Table 4 can be obtained. For example, when it is determined that the PUCCH is transmitted in the second sub - time slot, i.e., n index = 1, then:

[0310] Base station side: According to the above formula, it can be determined that in the target PUCCH resource set, consecutive K = 8 PUCCH resources correspond to one sub - time slot. The PRI indication value (i.e., the Δ PRI value) indicates one of the K PUCCH resources corresponding to one sub - time slot. As shown in Table 4, thus, the K PUCCH resources corresponding to each sub - time slot can be obtained. For example, for the first sub - time slot, it corresponds to the 1st to 8th PUCCH resources in the target PUCCH resource set. For the second sub - time slot, it corresponds to the 9th to 16th PUCCH resources in the target PUCCH resource set. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the second sub - time slot for transmitting the PUCCH in the second sub - time slot. For example, it is determined as the 9th PUCCH resource in the target PUCCH resource set, i.e., the PUCCH resource with the PUCCH resource number r PUCCH = 8. Then, the base station generates a PRI indication field corresponding to this PUCCH resource as "000" and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal in the second sub - time slot according to the determined PUCCH resource above;

[0311] Terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI = 0) and the sub - time slot number n index = 1 of the PUCCH, calculate r PUCCH = 8 according to the formula, which means using the 9th PUCCH resource in the target PUCCH resource set to perform PUCCH transmission in the second time slot;

[0312] For another example, when it is determined that PUCCH is transmitted in the first sub-slot, i.e., n index = 0, then:

[0313] At the base station side: Based on the same method as above, 8 PUCCH resources corresponding to each sub-slot are obtained. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the first sub-slot for transmitting the PUCCH in the first sub-slot. For example, it is determined as the 4th PUCCH resource in the target PUCCH resource set, i.e., the PUCCH resource with the resource number r PUCCH = 3. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "011" and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal in the first sub-slot according to the determined PUCCH resource above;

[0314] At the terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "011" (i.e., Δ PRI = 3) and the sub-slot number n index = 0 of the PUCCH, r can be calculated according to the formula PUCCH = 3, which means using the 4th PUCCH resource in the target PUCCH resource set to perform PUCCH transmission in the first time slot.

[0315] Table 4:

[0317]

[0318] Embodiment 6 (corresponding to Method 3): Assume that the determined target PUCCH resource set contains R PUCCH = 16 (i.e., R PUCCH = N * K) resources, one terminal corresponds to N = 2 TRPs, n index is the number of a TRP corresponding to a terminal, and the value range is 0 to N - 1. The PUCCH resource indication field contains 3-bit indication information and can indicate K = 8 states. The 3-bit PUCCH resource indication field can indicate numbers from 0 to 7. Then according to the formula r PUCCH = n index ·K + Δ PRIThe indication relationship shown in Table 4 can be obtained (by replacing the sub-slot numbers therein with TRP numbers). For example, when it is determined that the PUCCH corresponds to the second TRP, i.e., n index = 1, then:

[0319] On the base station side: According to the above formula, it can be determined that in the target PUCCH resource set, consecutive K = 8 PUCCH resources correspond to one TRP, and the PRI indication value (i.e., Δ PRI value) indicates one of the K PUCCH resources corresponding to one TRP. As shown in Table 4, thus the K PUCCH resources corresponding to each TRP can be obtained. For example, for the first TRP, it corresponds to the 8 PUCCH resources numbered 1 to 8 in the target PUCCH resource set. For the second TRP, it corresponds to the 8 PUCCH resources numbered 9 to 16 in the target PUCCH resource set. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the second TRP for transmitting the PUCCH corresponding to the second TRP. For example, it is determined to be the 9th PUCCH resource in the target PUCCH resource set, i.e., the PUCCH resource with the PUCCH resource number r PUCCH = 8. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "000" and sends it to the terminal through the PDCCH corresponding to the PUCCH; The base station receives the PUCCH sent by the terminal corresponding to the second TRP according to the PUCCH resource determined above;

[0320] On the terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI = 0) and the TRP number n index = 1 of the PUCCH, r PUCCH = 8 can be calculated according to the formula, which means using the 9th PUCCH resource in the target PUCCH resource set to transmit the PUCCH corresponding to the second TRP;

[0321] Again, for example, when it is determined that the PUCCH corresponds to the first TRP, i.e., n index = 0, then:

[0322] Base station side: Eight PUCCH resources corresponding to each TRP are obtained in the same manner as described above. The base station determines one PUCCH resource from the eight PUCCH resources corresponding to the first TRP for transmitting the PUCCH corresponding to the first TRP. For example, it is determined as the 4th PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource with resource number r PUCCH = 3. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "011" and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal corresponding to the first TRP according to the determined PUCCH resource above;

[0323] Terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "011" (i.e., Δ PRI = 3) and the TRP number n index = 0 of the PUCCH, r PUCCH = 3 can be calculated according to the formula, which means using the 4th PUCCH resource in the target PUCCH resource set to transmit the PUCCH corresponding to the first TRP.

[0324] When the PUCCH of a terminal is transmitted based on sub-slots, there are N1 sub-slots in one slot, and the terminal also corresponds to multiple TRPs (for example, N2 TRPs), the following method can be used:

[0325] Method A: Configure at least one PUCCH resource set independently for each sub-slot. In the target sub-slot where the PUCCH is transmitted, determine a target PUCCH resource set from at least one PUCCH resource set corresponding to the target sub-slot. In the target PUCCH resource set, determine the PUCCH resource according to the PUCCH resource indication field and the number of the TRP corresponding to the PUCCH, that is, in each sub-slot, determine the PUCCH resource corresponding to a certain TRP in a sub-slot in the same manner as when there are multiple TRPs described above;

[0326] For example, there are N1 = 4 sub-slots in one slot, and a terminal corresponds to N2 = 2 TRPs. Then a group of PUCCH resource sets can be configured for each sub-slot. A group of PUCCH resource sets can include one or more PUCCH resource sets. For example, it is determined that the PUCCH is transmitted in the second sub-slot and the PUCCH corresponds to the second TRP, then:

[0327] Base station side: Determine the target PUCCH resource set from the PUCCH resource set corresponding to the second sub-slot. The subsequent steps are the same as those in Embodiments 2, 4, and 6. The target PUCCH resource set here is the target resource set corresponding to the second sub-slot. In the second sub-slot, the base station receives the PUCCH corresponding to the second TRP sent by the terminal according to the PUCCH resources determined in the manner of Embodiments 2, 4, and 6.

[0328] Terminal side: Determine the target PUCCH resource set from the PUCCH resource set corresponding to the second sub-slot. The subsequent steps are the same as those in Embodiments 2, 4, and 6. The target PUCCH resource set here is the target resource set corresponding to the second sub-slot. In the second sub-slot, the terminal sends the PUCCH corresponding to the second TRP according to the PUCCH resources determined in the manner of Embodiments 2, 4, and 6.

[0329] Method B: Independently configure at least one PUCCH resource set for each TRP. Determine a target PUCCH resource set from at least one PUCCH resource set corresponding to the target TRP corresponding to the PUCCH. In the target PUCCH resource set, determine the PUCCH resource according to the PUCCH resource indication field and the number of the sub-slot corresponding to the PUCCH, that is, the PUCCH corresponding to different TRPs. Determine the PUCCH resource of a PUCCH corresponding to a certain TRP in a certain sub-slot according to the above method with multiple sub-slots.

[0330] For example, if a time slot contains N1 = 4 sub-slots and a terminal corresponds to N2 = 2 TRPs, then a group of PUCCH resource sets can be configured for each TRP. A group of PUCCH resource sets can contain one or more PUCCH resource sets. For example, determine that the PUCCH corresponds to the second TRP and is transmitted in the second time slot. Then:

[0331] Base station side: Determine the target PUCCH resource set from the PUCCH resource set corresponding to the second TRP. The subsequent steps are the same as those in Embodiments 1, 3, and 5. The target PUCCH resource set here is the target resource set corresponding to the second TRP. In the second sub-slot, the base station receives the PUCCH corresponding to the second TRP sent by the terminal according to the PUCCH resources determined in the manner of Embodiments 1, 3, and 5.

[0332] Terminal side: Determine the target PUCCH resource set from the PUCCH resource set corresponding to the second TRP. The subsequent steps are the same as those in Embodiments 1, 3, and 5. The target PUCCH resource set here is the target resource set corresponding to the second TRP. In the second sub-slot, the terminal sends the PUCCH corresponding to the second TRP on the PUCCH resource determined in the manner of Embodiments 2, 4, and 6.

[0333] Method C: Divide the M PUCCH resources in the target PUCCH resource set into N subsets. Each subset corresponds to one TRP and one sub-slot in one time slot, where N1 is the number of sub-slots in one time slot and N2 is the number of TRPs corresponding to the terminal. Determine a combined number according to the number of the sub-slot where the PUCCH transmission is located and the number of the TRP corresponding to the PUCCH. According to the combined number, determine the subset in the target PUCCH resource set corresponding to the TRP and the sub-slot. According to the PUCCH resource indication field, determine a PUCCH resource in the determined subset, where the PUCCH resource indication field indicates the number of the PUCCH resource in a subset; that is, combine and use the method of determining the PUCCH resource based on the sub-slot number (Method 1-1) and the TRP number (Method 1-2) above. By replacing the above N with N1*N2 and replacing the above n index n index as the combined number of N1 sub-slots and N2 TRPs;

[0334] For example, when N1 = 4 and N2 = 2, as shown in Table 5 or Table 6, the n index corresponding relationship with the combined number, reuse the method combining Embodiments 1 and 2 to determine the PUCCH resource. Wherein, when N1 = 4 and N2 = 2, assume that the target PUCCH resource set contains 64 resources, that is, divide the 64 PUCCH resources into N = N1*N2 = 8 subsets, and each subset contains 8 PUCCH resources. According to the number of the sub-slot corresponding to the PUCCH and the number of the TRP corresponding to the PUCCH, determine a combined number as shown in Table 5 or Table 6. For example, it is determined that the PUCCH is transmitted in the second sub-slot and corresponds to the second TRP. Then, according to Table 5, determine the combined number n index = 3. Thus, the subset corresponding to the combined number is the 4th subset among the 8 subsets into which the target PUCCH resource set is divided. Determine a PUCCH resource in this subset according to the PUCCH resource indication field. For example, if the PUCCH resource indication field is "000", it means the first PUCCH resource in this subset, that is, the 25th PUCCH resource in the target PUCCH resource set, as shown in Table 7;

[0346]

[0347] Mode D: Reuse Method 2 and Method 3, set N to N1*N2, and replace the above n index n index as the combined numbering for N1 sub-slots and N2 TRPs;

[0348] For example, when N1 = 4 and N2 = 2, the correspondence between n shown in Table 5 or Table 6 index and the combined numbering. For Method 2, reuse the method combining Embodiment 3 and 4 to determine the PUCCH resources. For Method 3, reuse the method combining Embodiment 5 and 6 to determine the PUCCH resources;

[0349] For example, for Method 2, when N1 = 4 and N2 = 2, assume that the target PUCCH resource set contains 64 resources. When it is determined that the PUCCH is transmitted in the second sub-slot and corresponds to the second TRP, then determine n according to Table 5 index = 3, then:

[0350] Base station side: According to the formulas in Embodiment 3 and 4, it can be determined that in the target PUCCH resource set, consecutive PUCCH resources correspond to one PRI indication value (i.e., Δ PRIvalue), as shown in Table 8, so that K PUCCH resources corresponding to each combined number (i.e., a combination of a sub - slot and a TRP) can be obtained. For example, for the first combined number (i.e., the first sub - slot and the first TRP), it corresponds to the 1st, 9th, 17th, 25th, 33rd, 41st, 49th, and 57th PUCCH resources in the target PUCCH resource set. For the second combined number (i.e., the first sub - slot and the second TRP), it corresponds to the 2nd, 10th, 18th, 26th, 34th, 42nd, 50th, and 58th PUCCH resources in the target PUCCH resource set, and so on. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the combined number n index = 3 to transmit the PUCCH corresponding to the second TRP in the second sub - slot. For example, it is determined as the 4th PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource with the number r PUCCH = 3. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "000" and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal corresponding to the second TRP in the second sub - slot according to the determined PUCCH resource above;

[0351] Terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI = 0) and the combined number n index = 3 corresponding to the PUCCH, calculate r PUCCH = 3 according to the formula, which means using the 4th PUCCH resource in the target PUCCH resource set to transmit the PUCCH corresponding to the second TRP in the second time slot;

[0358] For example, for Method 3, when N1 = 4 and N2 = 2, assuming that the target PUCCH resource set contains 64 resources, when it is determined that PUCCH is transmitted in the second sub-slot and corresponds to the second TRP, that is, n is determined according to Table 5 index = 3, then:

[0359] Base station side: According to the formulas in Embodiments 5 and 6, it can be determined that in the target PUCCH resource set, consecutive K = 8 PUCCH resources correspond to a combined number (that is, corresponding to a combination of a sub-slot and a TRP), so that the K PUCCH resources corresponding to each combined number can be obtained. The PRI indication value (i.e., Δ PRI value) indicates one of the K PUCCH resources corresponding to a combined number. As shown in Table 9, for example, for the first combined number, it corresponds to the 1st to 8th PUCCH resources in the target PUCCH resource set. For the second combined number, it corresponds to the 9th to 16th PUCCH resources in the target PUCCH resource set, and so on. The base station determines a PUCCH resource from the 8 PUCCH resources corresponding to the 4th combined number (i.e., n index = 3) to transmit the PUCCH corresponding to the second TRP in the second sub-slot. For example, it is determined to be the 25th PUCCH resource in the target PUCCH resource set, that is, the PUCCH resource with the PUCCH resource number r PUCCH = 24. Then the base station generates a PRI indication field corresponding to this PUCCH resource as "000" and sends it to the terminal through the PDCCH corresponding to the PUCCH; the base station receives the PUCCH sent by the terminal corresponding to the second TRP in the second sub-slot according to the determined PUCCH resource above;

[0360] Terminal side: Receive the PDCCH corresponding to the PUCCH and obtain the PUCCH resource indication field carried in the PDCCH (when there are multiple PDCCHs corresponding to the PUCCH, determine the PUCCH resource according to the PUCCH resource indication carried in the last PDCCH). According to the PUCCH resource indication field indicating "000" (i.e., Δ PRI = 0) and the combined number n index = 3 corresponding to the PUCCH, r can be calculated according to the formula PUCCH = 24, which means using the 25th PUCCH resource in the target PUCCH resource set to transmit the PUCCH corresponding to the second TRP in the second time slot;

[0367] In summary, in the embodiments of the present application, by reusing the configuration method of the existing PUCCH resource set, the number of PUCCH resources in a PUCCH resource set is extended. According to the PUCCH resource indication field and the corresponding target number of the PUCCH (such as sub-slot number, or TRP number, etc.), the PUCCH resources corresponding to different sub-slots or TRPs in a PUCCH resource set can be determined.
