Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This disclosure claims priority to Chinese Patent Application No. 202111138643.9, filed in China on September 27, 2021, the entire contents of which are incorporated herein by reference. The present disclosure relates to the field of communication technologies, and more particularly to a method and apparatus for determining power control parameters. [Background technology]

[0002] The Physical Uplink Control Channel (PUCCH) carries uplink control information (UCI) and controls the transmission power of the PUCCH. When the UCI includes feedback information of a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK), a power control parameter for feeding back the HARQ-ACK needs to be calculated, and the parameter is for the transmission power of the PUCCH. When the number of bits of the UCI exceeds 11, the power control parameter is calculated according to the length of the HARQ-ACK codebook. When the number of bits of the UCI is 11 or less, the power control parameter needs to be calculated according to the scheduling downlink control information (DCI) received by the terminal.

[0003] In the related technology, when a terminal receives multiple broadcast groupcast services, the base station configures multiple terminal (User Equipment, UE)-based Radio Network Temporary Identifiers (G-RNTIs) for the terminal to identify different broadcast groupcast services. For Type-2 codebook generation, different broadcast groupcast services individually count a Downlink Assignment Index (DAI) and generate their own HARQ sub-codebooks. Therefore, the terminal generates multiple HARQ-ACK sub-codebooks for the broadcast groupcast and transmits them on the PUCCH. However, the calculation method of HARQ-ACK for the sub-codebook of a transmission block for unicast in the related technology cannot be applied to the PUCCH power control parameters for groupcast.

Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without paying creative labor shall all fall within the scope of protection of the present application.

[0089] In describing the embodiments of the present disclosure, we first explain and explain some concepts that will be used in the following description.

[0090] 1. HARQ-ACK dynamic codebook (type-2) mechanism. The 5G system supports a dynamic HARQ-ACK codebook generation mechanism. The principle is that a DAI indication is added when sending scheduling signaling DCI, and the terminal calculates the number of DCI and physical downlink shared channels (PDSCHs) actually sent from the base station according to the DAI count, thereby determining the number of PDSCHs that need feedback and are included in the HARQ-ACK codebook.

[0091] Below, we describe the procedure of the HARQ-ACK dynamic codebook mechanism for a single-carrier scenario (C-DAI only). As shown in Figure 1, it is assumed that nine DCIs for scheduling PDSCH are transmitted from the base station, and each DCI is designated as DCI-1 to DCI-9. The bit width of the DAI count is 2 bits, that is, the maximum count range is T D = 4. j is the number of cycles used by the terminal to calculate the DAI value (if the DAI in the current DCI is equal to or less than the DAI in the previous DCI, j is incremented by 1).

[0092] The DAI counting mechanism allows the terminal to calculate the number of DCIs sent from the base station, and the calculation method is as follows:

[0093] It should be noted that in a multi-carrier scenario, in addition to C-DAI, there is also a Total DAI (T-DAI) that counts all carriers.

[0094] Specifically, the embodiments of the present disclosure provide a power control parameter determination method that solves the problem that the conventional method for calculating HARQ-ACK of a sub-codebook of a transmission block for unicast cannot be applied to the PUCCH power control parameters for groupcast.

[0095] As shown in FIG. 2, the embodiment of the present disclosure provides a power control parameter determination method, which specifically includes the following steps 21 to 22.

[0096] Step 21 is for the terminal to obtain the unicast related parameters and the groupcast related parameters.

[0097] The unicast-related parameters include, for example, the number of unicast transmission blocks received by the terminal, the number of semi-persistent scheduling transmission blocks for unicast received by the terminal, a downlink allocation index (DAI) parameter of the last DCI among the unicast DCIs, the number of unicast DCIs received by the terminal, and unicast-related configuration information, etc. If one or more unicast-related parameters cannot be acquired, the unacquired related parameters may be represented as 0.

[0098] The groupcast-related parameters may include at least one of the following: a downlink allocation index (DAI) parameter of the last DCI among the groupcast downlink control information (DCI); the number of groupcast DCIs received by the terminal; the number of groupcast transmission blocks received by the terminal; and the number of semi-persistent scheduling transmission blocks for the groupcast received by the terminal.

[0099] It should be noted that the unicast-related parameters and the groupcast-related parameters include, but are not limited to, one or more of the above parameters, and may further include other parameter information for determining the power control parameters of the PUCCH of the groupcast HARQ-ACK.

[0100] It should be noted that the unicast refers to scheduling and data transmission using Point to Point (PTP), which may also be referred to as single UE-based scheduling. The unicast service in the embodiments of the present application refers to service data transmitted in a unicast manner.

[0101] The groupcast refers to data scheduled using Point to Multi-point (PTM) and may also be referred to as group UE-based scheduling. The groupcast service in the present embodiment refers to service data transmitted in a multicast manner.

[0102] The unicast related parameters and the groupcast related parameters may be downlink data or sidelink data.

[0103] Step 22 is for the terminal to determine a power control parameter of a physical uplink control channel (PUCCH) according to the unicast related parameters and the groupcast related parameters.

[0104] In this embodiment, when determining the PUCCH power control parameter, the UE may use one or more of the above parameters to determine it, for example, determine the PUCCH power control parameter according to parameters such as the DAI parameter of the last DCI among one or more groupcast DCI scheduling information, the number of groupcast scheduling signalings (i.e., the number of DCIs) received by the UE, the number of groupcast transport blocks received by the UE, the number of transport blocks of semi-persistent scheduling for groupcast, etc. The power control parameter refers to the PUCCH power control parameter for transmitting HARQ-ACK.

[0105] Optionally, the PUCCH power control parameters refer to the power control parameters that need to be fed back as HARQ-ACK, and the HARQ-ACK feedback is based on Acknowledgement (ACK) / Negative Acknowledgement (NACK) (i.e., if the data is not correctly decoded, NACK is fed back, and if the data is correctly decoded, ACK is fed back). HARQ-ACK feedback other than ACK / NACK is not included, specifically: It does not include scheduling signaling and related transmission blocks that do not require HARQ-ACK feedback; HARQ-ACK is based on negative acknowledgement only (NACK-only) (i.e., feedback NACK if not correctly decoded, and no information if correctly decoded). It does not include scheduling signaling and associated transmission blocks, while It may also include associated DCI and transport blocks that convert NACK-only to ACK / NACK feedback according to certain conditions.

[0106] According to an embodiment of the present application, the terminal determines the power control parameters of the PUCCH channel for transmitting the broadcast groupcast HARQ-ACK codebook according to the unicast related parameters and the groupcast related parameters, so that the terminal can perform power control more optimally, thereby maximizing power efficiency and saving power energy while meeting the requirements for PUCCH transmission power.

[0107] Hereinafter, a method for determining the power control parameters by the terminal according to the unicast-related parameters and the groupcast-related parameters will be described through specific embodiments.

[0108] As an alternative embodiment, when determining the power control parameters of the PUCCH according to the unicast-related parameters and the groupcast-related parameters, the power control parameters of the unicast service and the groupcast service may be calculated separately, and specifically, step 22 may include the following steps 31 to 33.

[0109] Step 31 is to determine a first power control parameter of the unicast service according to the relevant parameters of the unicast.

[0110] Optionally, the terminal determines, according to unicast-related parameters, a number of unicast undetected transmission blocks corresponding to undetected DCI in the unicast service by the terminal, determines, according to unicast-related parameters, a number of unicast received transmission blocks corresponding to DCI received in the unicast service by the terminal, and determines the first power control parameter according to the number of unicast undetected transmission blocks and the number of unicast received transmission blocks, where the first power control parameter is the sum of the number of unicast undetected transmission blocks and the number of unicast received transmission blocks.

[0111] Specifically, the number of unicast undetected transmission blocks and the number of unicast received transmission blocks may be calculated according to the DAI parameter of the last DCI among the DCIs of the unicast service, the number of unicast DCIs received by the terminal, the number of all unicast transmission blocks received by the terminal, the number of unicast semi-persistent scheduling transmission blocks received by the terminal, and unicast configuration information configured by the base station.

[0112] Step 32 is to determine second power control parameters for N (N is an integer equal to or greater than 1) groupcast services according to the related parameters of the groupcast services.

[0113] Optionally, determining the second power control parameters of the N groupcast services according to the above-mentioned groupcast related parameters includes respectively determining the number of missed detection transmission blocks corresponding to missed DCI in each groupcast service by the terminal according to the groupcast related parameters; respectively determining the number of received transmission blocks corresponding to DCI received in each groupcast service by the terminal according to the groupcast related parameters; and determining second power control parameters of the N groupcast services according to the number of missed detection transmission blocks and the number of received transmission blocks. Here, the sum of the number of undetected transmission blocks and the number of received transmission blocks is a second power control parameter for the groupcast service.

[0114] Step 33 is to determine a power control parameter of the PUCCH according to the first power parameter and the second power parameter.

[0115] In this embodiment, the sum of the first power parameter and the second power parameters of the N groupcast services is the power control parameter of the PUCCH.

[0116] Furthermore, when calculating the second power control parameter for each groupcast service in step 32, the number of undetected transmission blocks and the number of received transmission blocks for each groupcast service need to be calculated, and the sum of the number of undetected transmission blocks and the number of received transmission blocks corresponding to the target groupcast service is the second power control parameter for the target groupcast service.

[0117] Among them, the methods for respectively determining the number of missed detection transmission blocks corresponding to missed detection DCI in each of the N groupcast services provided by the terminal according to the above-mentioned groupcast-related parameters may include the following methods 1 and 2:

[0118] Method 1 is to subtract the DAI parameter of the last DCI corresponding to the target groupcast service from the number of DCIs of the target groupcast service received by the terminal to obtain the number of DCIs missed by the terminal in the target groupcast service, perform a modulo operation on the number of DCIs missed by the terminal and the maximum count value of the DAI count, and multiply the operation result by the first groupcast configuration information to obtain the number of missed detection transmission blocks corresponding to the missed detection DCIs in the target groupcast service by the terminal, where the target groupcast service is any one of the N groupcast services.

[0119] In the first method, for example, if the target groupcast service is groupcast service (i), the number of missed detection transmission blocks corresponding to missed detection DCI in groupcast service (i) by the terminal is specifically expressed as follows: HARQ-ACK,part1(G-RNTI(i)) may be represented by

number

number

number

number

[0120] Method 2 is to obtain the product of the DAI cycle number of the target groupcast service and the maximum count value of the DAI count, obtain the sum of this product and the DAI parameter of the last DCI corresponding to the target groupcast service received by the terminal, subtract this sum from the number of DCIs of the target groupcast service received by the terminal to obtain a first calculation result, and multiply the first calculation result by first groupcast configuration information to obtain the number of missed detection transmission blocks corresponding to missed detection DCIs in the target groupcast service by the terminal, where the target groupcast service is any one of the N groupcast services.

[0121] It should be noted that if the first groupcast configuration information is 1, the above-mentioned step of "multiplying the first calculation result by the first groupcast configuration information" may be omitted.

[0122] Regarding the second method, for example, if the target groupcast service is groupcast service (i), the number of missed detection transmission blocks corresponding to missed detection DCI in groupcast service (i) by the terminal is specifically expressed as follows: HARQ-ACK,part1(G-RNTI(i)) may be represented by

number

[0123] It should be noted that in method 1, the bit width of the DAI count is 2 bits, that is, the maximum count range is T D = 4, and when calculating the number of missed detection transmission blocks corresponding to missed detection DCI, the method of method 1 is used to calculate T D The modulus may be calculated for

[0124] Of these, there are two main considerations: (1) When the number of DCIs transmitted from the base station is 11 or less, the number of DCIs missed by the terminal does not exceed three. (2) Formula

number

[0125] If the terminal supports scheduling of multicast groupcast services, and the number of missed DCIs exceeds three due to special reasons, such as the mobile terminal joining an HARQ procedure already in progress, the number of missed transmission blocks corresponding to missed DCIs may be calculated using the method in the second method above.

[0126] Wherein, determining the number of received transmission blocks corresponding to the DCI received by the terminal in each groupcast service according to the groupcast related parameters; The method may include determining the number of received transmission blocks corresponding to DCI received by the terminal in the target groupcast service by calculating the sum of the number of transmission blocks of the target groupcast service received by the terminal and the number of transmission blocks of semi-persistent scheduling of the target groupcast service, where the target groupcast service is any one of the N groupcast services.

[0127] Regarding the number of received transmission blocks, for example, if the target groupcast service is groupcast service (i), the number of received transmission blocks corresponding to DCI received by the terminal in groupcast service (i) is specifically expressed as follows: HARQ-ACK,part2(G-RNTI(i)) may be represented by

[0128] In the following, in this alternative embodiment, the actual procedure for determining the power control parameters of the PUCCH according to the unicast related parameters and the groupcast related parameters will be described through specific examples.

[0129] In this embodiment, the unicast and each groupcast service calculates its own power control parameter separately, and the power control parameter of the PUCCH can be obtained by summing each of the separately calculated first power control parameters and the N second power control parameters, that is,

[0133] Wherein, if the base station is configured to schedule the maximum codeword in the DCI as 2, i.e., to schedule two transmission blocks, and needs to feed back 2 bits of information, then:

number

[0134] Alternatively, when semi-persistent scheduling is configured for a groupcast service, for ease of operation, the HARQ-ACK feedback information lengths of groupcast and unicast semi-persistent scheduling may be calculated together and included in the HARQ-ACK codebook of the unicast service, i.e., the transmission blocks of unicast and groupcast semi-persistent scheduling may be included when calculating the unicast power control parameters. In this case, the HARQ-ACK feedback length of groupcast semi-persistent scheduling is not included when calculating the groupcast HARQ codebook, i.e., the number of transmission blocks of groupcast semi-persistent scheduling is not included when calculating the groupcast power control parameters.

[0135] Alternatively, if the transmission block of semi-persistent scheduling of groupcast service is not included in the calculation of the power control parameters of unicast service, in addition to calculating the transmission block based on dynamic scheduling and the corresponding HARQ-ACK feedback, it is also necessary to calculate the HARQ-ACK feedback length of semi-persistent scheduling of groupcast. That is, when calculating the power control parameters of groupcast, it is necessary to calculate the transmission block of dynamic scheduling and semi-persistent scheduling of groupcast.

[0136] Alternatively, if the terminal supports scheduling of multicast groupcast services, if the number of missing DCIs exceeds three due to some special reason, for example, due to the mobile terminal joining an HARQ procedure already in progress, the above n HARQ-ACK,TB(G-RNTI(i)) In the formula, the calculation procedure for finding the modulus is as follows:

number

number

[0137] The first power control parameter for unicast may be calculated in the conventional manner or may be replaced by the above-described manner. The replaced first power control parameter n HARQ-ACK,TB(unicast) The calculation method is as follows:

number

[0138] In this embodiment, the unicast service and each groupcast service separately calculate their own power control parameters, and the power control parameters of the unicast service and all groupcast services are summed to obtain the power control parameter of the PUCCH. Since the existing protocol content can be easily modified and the calculation of the power control parameter of the PUCCH channel carrying the HARQ-ACK codebook of the broadcast groupcast can be realized, the terminal can perform power control more efficiently, thereby maximizing power efficiency.

[0139] As an alternative embodiment, when determining the power control parameters of the PUCCH according to the unicast related parameters and the groupcast related parameters, the number of missed detection transmission blocks in the unicast service and the groupcast service by the terminal and the number of received transmission blocks in the unicast service and the groupcast service by the terminal may be calculated respectively, and the power control parameters of the PUCCH may be determined according to the number of missed detection transmission blocks and the number of received transmission blocks. Specifically, step 22 may include the following steps 41 to 43.

[0140] Step 41 is to determine the total number of missed detection transmission blocks corresponding to missed detection DCIs in the unicast service and N (N is an integer greater than or equal to 1) groupcast services by the terminal according to the unicast related parameters and the groupcast related parameters.

[0141] Step 42 is to determine the total number of received transmission blocks corresponding to the DCI received by the terminal in the unicast service and the groupcast service according to the unicast related parameters and the groupcast related parameters.

[0142] Step 43 is to determine a power control parameter of the PUCCH according to the total number of missed detection transmission blocks and the total number of received transmission blocks.

[0143] In this embodiment, the total number of missed detection transmission blocks and the total number of received transmission blocks are respectively determined, and the total number of missed detection transmission blocks and the total number of received transmission blocks are summed to obtain the power control parameter of the PUCCH. Specifically, when determining the total number of missed detection transmission blocks and the total number of received transmission blocks, multiple implementation methods may be included, such as the following method 1 to method 3.

[0144] Method 1 is to determine the number of missed detection transmission blocks for each unicast service and each groupcast service separately, and then sum the numbers of missed detection transmission blocks corresponding to the unicast service and all groupcast services to obtain the total number of missed detection transmission blocks. The total number of received transmission blocks can be calculated jointly for the unicast service and each groupcast service.

[0145] Method 2 is to determine the number of missed detection transmission blocks individually for a unicast service, and jointly determine the number of missed detection transmission blocks for N groupcast services, and then sum the numbers of missed detection transmission blocks corresponding to the unicast service and the N groupcast services to obtain the total number of missed detection transmission blocks, and the total number of received transmission blocks can be jointly calculated for the unicast service and each groupcast service.

[0146] Method 3: for a unicast service and N groupcast services, the total number of missed transmission blocks is determined jointly, and the total number of received transmission blocks is determined jointly.

[0147] The above three realization methods will be specifically explained below through examples.

[0148] Alternatively, in method 1, the unicast service and each groupcast service individually determine the number of missed detection transmission blocks, and the total number of missed detection transmission blocks is obtained by summing the numbers of missed detection transmission blocks corresponding to the unicast service and all groupcast services.

[0149] Specifically, the step 41 may include the following steps 411 to 413. Step 411 is to determine the number of unicast missed detection transmission blocks corresponding to the missed detection DCI in the unicast service by the terminal according to the relevant parameters of the unicast. Step 412 is to respectively determine the number of missed detection transmission blocks corresponding to missed detection DCI in each groupcast service by the terminal according to the relevant parameters of the groupcast. Step 413 is to determine the total number of missed detection transmission blocks according to the number of missed detection transmission blocks of unicast services and the number of missed detection transmission blocks corresponding to each groupcast service respectively.

[0150] The total number of missed detection transmission blocks is obtained by adding the number of missed detection transmission blocks of the unicast services and the number of missed detection transmission blocks of the N groupcast services. HARQ-ACK,part1 The calculation method is as follows:

number

[0151] Optionally, in the above step 412, determining the number of missed detection transmission blocks corresponding to each groupcast service may include the following methods (1) and (2).

[0152] Method (1) is to subtract the DAI parameter of the last DCI corresponding to the target groupcast service from the number of DCIs of the target groupcast service received by the terminal to obtain the number of DCIs missed by the terminal in the target groupcast service, perform a modulo operation on the number of DCIs missed by the terminal and the maximum count value of the DAI count, and multiply the operation result by the first groupcast configuration information to obtain the number of missed detection transmission blocks corresponding to the missed detection DCIs in the target groupcast service by the terminal, where the target groupcast service is any one of the N groupcast services.

[0153] In the above method (1), for example, if the target groupcast service is groupcast service (i), the number of missed detection transmission blocks corresponding to missed detection DCI in groupcast service (i) by the terminal is specifically expressed as follows: HARQ-ACK,part1(G-RNTI(i)) may be represented by

number

number

[0154] Method (2) is to obtain the product of the DAI cycle number of the target groupcast service and the maximum count value of the DAI count, obtain the sum of this product and the DAI parameter of the last DCI corresponding to the target groupcast service received by the terminal, subtract this sum from the number of DCIs of the target groupcast service received by the terminal to obtain a first calculation result, and multiply the first calculation result by first groupcast configuration information to obtain the number of missed detection transmission blocks corresponding to the missed detection DCI in the target groupcast service by the terminal, where the target groupcast service is any one of the N groupcast services.

[0155] It should be noted that if the first groupcast configuration information is 1, the above-mentioned step of "multiplying the first calculation result by the first groupcast configuration information" may be omitted.

[0156] Regarding the method (2), for example, if the target groupcast service is groupcast service (i), the number of missed detection transmission blocks corresponding to missed detection DCI in groupcast service (i) by the terminal is specifically expressed as follows: HARQ-ACK,part1(G-RNTI(i)) may be represented by

number

[0157] It should be noted that in method (1), the bit width of the DAI count is 2 bits, that is, the maximum count range is T D = 4, and when calculating the number of missed detection transmission blocks corresponding to missed detection DCI, the above method (1) is used to calculate T D The modulus may be calculated for

[0158] Of these, there are two main considerations: (1) When the number of DCIs transmitted from the base station is 11 or less, the number of DCIs missed by the terminal does not exceed three. (2) Formula

number

[0159] If the terminal supports scheduling of multicast groupcast services, and the number of missed DCIs exceeds three due to special reasons, such as the mobile terminal joining an HARQ procedure already in progress, the method of method (2) above may be used to calculate the number of missed transmission blocks corresponding to missed DCIs.

[0160] After determining the number of missed detection transmission blocks corresponding to each groupcast service through the above method, the total number of missed detection transmission blocks is obtained by adding the number of missed detection transmission blocks and the number of unicast missed detection transmission blocks corresponding to missed detection DCI in the unicast service by the terminal.

[0161] Alternatively, determining the total number of received transmission blocks corresponding to DCIs received by the terminal for the unicast service and the groupcast service according to the above-mentioned unicast-related parameters and the groupcast-related parameters may include determining the total number of received transmission blocks according to the total number of transmission blocks of the unicast service and N groupcast services received by the terminal and the total number of transmission blocks of semi-persistent scheduling of the unicast service and the groupcast service.

[0162] In this embodiment, the number of received transmission blocks in the unicast service and N groupcast services may be jointly calculated. Specifically, the total number of received transmission blocks n corresponding to DCIs received by the terminal in the unicast service and the groupcast service may be calculated as follows: HARQ-ACK,part2 is calculated as follows:

[0163] Hereinafter, the actual procedure for determining the PUCCH power control parameters using Method 1 will be described through a specific example.

[0164] In this embodiment, the number of missed detection transmission blocks for each unicast service and each groupcast service is calculated separately, the number of missed detection transmission blocks for each unicast service and all groupcast services is summed to obtain the total number of missed detection transmission blocks, and the total number of received transmission blocks for each unicast service and N groupcast services is jointly calculated. The total number of missed detection transmission blocks and the total number of received transmission blocks are summed to obtain the power control parameter for the PUCCH, that is,

[0168] Alternatively, in this embodiment, when semi-persistent scheduling is configured for a groupcast service, the HARQ-ACK feedback information lengths of the groupcast and unicast semi-persistent scheduling may be calculated together and included in the HARQ-ACK codebook of the unicast service, i.e., the total number of transmission blocks of the unicast and groupcast semi-persistent scheduling may be included when calculating the unicast power control parameters. In this case, the HARQ-ACK feedback length of the groupcast semi-persistent scheduling is not included when calculating the groupcast HARQ codebook, i.e., the number of transmission blocks of the groupcast semi-persistent scheduling is not included when calculating the groupcast power control parameters.

[0169] If the transmission block of semi-persistent scheduling of groupcast service is not included in the calculation of power control parameters of unicast service, in addition to calculating the transmission block based on dynamic scheduling and the corresponding HARQ-ACK feedback, it is also necessary to calculate the HARQ-ACK feedback length of semi-persistent scheduling of groupcast. That is, when calculating power control parameters of groupcast, it is necessary to calculate the transmission block of dynamic scheduling and semi-persistent scheduling of groupcast.

[0170] In one embodiment of this method, the number of missed detection transmission blocks is calculated independently for each unicast service and each groupcast service, and the total number of missed detection transmission blocks is obtained by adding up the numbers of missed detection transmission blocks corresponding to the unicast service and all groupcast services. Part 2 (i.e., the total number of received transmission blocks) is calculated in an integrated manner, which simplifies the calculation procedure.

[0171] Alternatively, in method 2, for a unicast service, the number of missed detection transmission blocks is determined individually, and for N groupcast services, the number of missed detection transmission blocks is determined jointly, and the total number of missed detection transmission blocks is obtained by summing the numbers of missed detection transmission blocks corresponding to the unicast service and the N groupcast services.

[0172] Specifically, the step 41 may include the following steps 511 to 513. Step 511 is to determine the number of unicast missed detection transmission blocks corresponding to the missed detection DCI in the unicast service by the terminal according to the relevant parameters of the unicast. Step 512 is to determine the number of groupcast missed detection transmission blocks corresponding to the missed detection DCI in the N groupcast services by the terminal according to the related parameters of the groupcast, which is the total number of missed detection transmission blocks in the N groupcast services by the terminal. Step 513 is to determine the total number of missed detection transmission blocks according to the number of unicast missed detection transmission blocks and the number of groupcast missed detection transmission blocks.

[0173] Wherein, determining the total number of missed detection transmission blocks according to the number of unicast missed detection transmission blocks and the number of groupcast missed detection transmission blocks is: The method includes calculating the sum of the number of unicast missed detection transmission blocks and the number of groupcast missed detection transmission blocks to obtain the total number of missed detection transmission blocks. HARQ-ACK,part1 The calculation method is as follows: n HARQ-ACK,part1 =n HARQ-ACK,part1(unicast) +n HARQ-ACK,part1(G-RNTI) where n HARQ-ACK,part1(unicast) represents the number of unicast missed transmission blocks of the unicast service, and n HARQ-ACK,part1(G-RNTI) represents the total number of undetected transmission blocks of N groupcast services.

[0174] Optionally, in the above step 512, when the terminal determines the number of missed groupcast transmission blocks corresponding to missed groupcast DCIs in the N groupcast services, the terminal may include the following methods (i) and (ii): Method (i) is to subtract the sum of the DAI parameters of the last DCIs corresponding to the N groupcast services from the sum of the number of DCIs of the N groupcast services received by the terminal to obtain the total number of DCIs missed by the terminal, perform a modulo operation on the total number of DCIs missed by the terminal and the maximum count value of the DAI count, and multiply the operation result by the first groupcast configuration information to obtain the number of groupcast missed transmission blocks corresponding to the missed DCIs in the N groupcast services received by the terminal.

[0175] In the method (i), the total number of undetected transmission blocks in N groupcast services by the terminal is specifically expressed as follows: HARQ-ACK,part1(G-RNTI) may be represented by

[0176] Method (ii) is to obtain the product of the number of DAI cycles of the target groupcast service and the maximum count value of the DAI count, add the product to the number of DCIs of the target groupcast service received by the terminal to obtain a second operation result, obtain the sum of the second operation results corresponding to the N groupcast services, subtract the sum from the sum of the number of DCIs of the N groupcast services received by the terminal to obtain a third operation result, and multiply the third operation result by the first groupcast configuration information to obtain the number of missed detection transmission blocks corresponding to the missed detection DCIs in the N groupcast services by the terminal.

[0177] In the method (ii), the total number of undetected transmission blocks in N groupcast services by the terminal is specifically expressed as follows: HARQ-ACK,part1(G-RNTI) may be represented by

number

[0178] It should be noted that in the case of method (i), the bit width of the DAI count is 2 bits, that is, the maximum count range is T D= 4, and when calculating the number of missed detection transmission blocks corresponding to missed detection DCI, the above method (i) is used to calculate T D The modulus may be calculated for

[0179] Of these, there are two main considerations: (1) When the number of DCIs transmitted from the base station is 11 or less, the number of DCIs missed by the terminal does not exceed three. (2) Formula

number

[0180] If the terminal supports scheduling of multicast groupcast services, and the number of missed DCIs exceeds three due to special reasons, such as the mobile terminal joining an HARQ procedure already in progress, the method of method (ii) above may be used to calculate the number of missed transmission blocks corresponding to missed DCIs.

[0181] After determining the number of groupcast missed detection transmission blocks corresponding to missed detection DCIs in the N groupcast services by the terminal through the above method, the total number of missed detection transmission blocks is obtained by adding the number of groupcast missed detection transmission blocks and the number of unicast missed detection transmission blocks corresponding to missed detection DCIs in the unicast service by the terminal in step 511.

[0182] Alternatively, determining the total number of received transmission blocks corresponding to DCIs received by the terminal for the unicast service and the groupcast service according to the above-mentioned unicast-related parameters and the groupcast-related parameters may include determining the total number of received transmission blocks according to the total number of transmission blocks of the unicast service and N groupcast services received by the terminal and the total number of transmission blocks of semi-persistent scheduling of the unicast service and the groupcast service.

[0183] Hereinafter, the actual procedure for determining the PUCCH power control parameters using Method 2 will be described through a specific example.

[0184] In this embodiment, the number of unicast missed detection transmission blocks corresponding to the unicast service is calculated individually, and the number of groupcast missed detection transmission blocks is jointly calculated for the N groupcast services. The number of unicast missed detection transmission blocks and the number of groupcast missed detection transmission blocks are summed to obtain the total number of missed detection transmission blocks, and the total number of received transmission blocks corresponding to the unicast service and the N groupcast services is jointly calculated. The total number of missed detection transmission blocks and the total number of received transmission blocks are summed to obtain the power control parameter for the PUCCH, that is,

[0185] It should be noted that in this embodiment, for the transmission of a broadcast groupcast service, the base station generally does not schedule two codewords in one DCI, that is, the parameter

[0186] Alternatively, if the terminal supports scheduling of multicast groupcast services, if the number of missing DCIs exceeds three due to some special reason, for example, due to the mobile terminal joining an HARQ procedure already in progress, the above n HARQ-ACK,part1(G-RNTI) may be replaced by the following formula:

number

[0187] Alternatively, in this embodiment, when semi-persistent scheduling is configured for a groupcast service, the HARQ-ACK feedback information lengths of the groupcast and unicast semi-persistent scheduling may be calculated together and included in the HARQ-ACK codebook of the unicast service, i.e., the total number of transmission blocks of the unicast and groupcast semi-persistent scheduling may be included when calculating the unicast power control parameters. In this case, the HARQ-ACK feedback length of the groupcast semi-persistent scheduling is not included when calculating the groupcast HARQ codebook, i.e., the number of transmission blocks of the groupcast semi-persistent scheduling is not included when calculating the groupcast power control parameters.

[0188] If the transmission block of semi-persistent scheduling of groupcast service is not included in the calculation of power control parameters of unicast service, in addition to calculating the transmission block based on dynamic scheduling and the corresponding HARQ-ACK feedback, it is also necessary to calculate the HARQ-ACK feedback length of semi-persistent scheduling of groupcast. That is, when calculating power control parameters of groupcast, it is necessary to calculate the transmission block of dynamic scheduling and semi-persistent scheduling of groupcast.

[0189] In the second embodiment of the method, the number of missed detection transmission blocks is determined individually for a unicast service, and the number of missed detection transmission blocks for N groupcast services is determined jointly, and the total number of missed detection transmission blocks is obtained by adding up the numbers of missed detection transmission blocks corresponding to the unicast service and the N groupcast services. Part 2 (i.e., the total number of received transmission blocks) is calculated jointly, which reduces the number of parameters that need to be calculated individually and simplifies the calculation procedure.

[0190] Optionally, in the third method, the unicast service and the N groupcast services jointly determine the total number of missed transmission blocks, and jointly determine the total number of received transmission blocks, i.e.,

number

number

[0191] Specifically, in step 41, the implementation method for calculating the total number of missed detection transmission blocks may include the following method (a) and method (b).

[0192] Method (a) is to obtain the sum of the DAI parameter of the last DCI among the DCIs of the unicast service and the DAI parameter of the last DCI corresponding to N groupcast services, subtract this sum from the total number of DCIs received by the terminal to obtain the total number of missed detection DCIs by the terminal, perform a modulo operation on the total number of missed detection DCIs by the terminal and the maximum count value of the DAI count, and multiply the operation result by the first groupcast configuration information to obtain the total number of missed detection transmission blocks corresponding to missed detection DCIs in the unicast service and the N groupcast services by the terminal. HARQ-ACK,part1 The calculation formula is as follows:

[0193] Alternatively, if the terminal supports scheduling of multicast groupcast services, if the number of missed DCIs exceeds three due to some special reason, such as the mobile terminal joining an HARQ procedure already in progress, the total number of missed transmission blocks may be calculated using method (b).

[0194] As a method (b), determining a total number of missed detection transmission blocks corresponding to missed detection DCIs in the unicast service and the N groupcast services by a terminal according to the above-mentioned unicast-related parameters and the groupcast-related parameters includes: calculating the total number of missed transmission blocks using the following formula:

[0195] Optionally, determining the total number of received transmission blocks corresponding to DCIs received by the terminal for the unicast service and the groupcast service according to the above-mentioned unicast-related parameters and the groupcast-related parameters includes determining the total number of received transmission blocks according to the total number of transmission blocks for the unicast service and N groupcast services received by the terminal and the total number of transmission blocks of semi-persistent scheduling for the unicast service and the groupcast service.

[0196] In this embodiment, the total number of received transmission blocks n HARQ-ACK,part2 is calculated as follows:

number

number

[0197] In an embodiment of method 3, for a unicast service and N groupcast services, the total number of missed detection transmission blocks is determined jointly, and the total number of received transmission blocks is determined jointly. Since the calculation procedure is simple, the terminal can more effectively perform power control, thereby maximizing power efficiency.

[0198] As an alternative embodiment, in the embodiment of the present application, if the first groupcast configuration information is 1, the power control parameter of the target groupcast service is the number of bits of the HARQ-ACK sub-codebook of the target groupcast service fed back on one PUCCH by the terminal corresponding to the target groupcast service.

[0199] Alternatively, the number of transmission blocks of semi-persistent scheduling of the target groupcast service is included in the number of bits of the HARQ-ACK sub-codebook of the target groupcast service; or or The number of transmission blocks of semi-persistent scheduling of the target groupcast service is included in the number of bits of the HARQ-ACK sub-codebook of the unicast service.

[0200] In this embodiment, when semi-persistent scheduling is configured for a groupcast service, the HARQ-ACK feedback information lengths for groupcast and unicast semi-persistent scheduling may be calculated together and included in the HARQ-ACK codebook for the unicast service, i.e., the transmission blocks for unicast and groupcast semi-persistent scheduling may be included when calculating the unicast power control parameters. In this case, the HARQ-ACK feedback length for groupcast semi-persistent scheduling is not included when calculating the groupcast HARQ codebook, i.e., the number of transmission blocks for groupcast semi-persistent scheduling is not included when calculating the groupcast power control parameters. If the transmission blocks for groupcast semi-persistent scheduling are not included in the calculation of the unicast service power control parameters, in addition to calculating the transmission blocks based on dynamic scheduling and the corresponding HARQ-ACK feedback, the HARQ-ACK feedback length for groupcast semi-persistent scheduling also needs to be calculated, i.e., the transmission blocks for groupcast dynamic scheduling and semi-persistent scheduling need to be calculated when calculating the groupcast power control parameters.

[0201] In this embodiment, the number of semi-persistent scheduling transmission blocks of the target groupcast service may be included in the number of bits of the HARQ-ACK sub-codebook of the target groupcast service, or may be included in the number of bits of the HARQ-ACK sub-codebook of the unicast service. Wherein, if the semi-persistent scheduling transmission blocks of the groupcast service are not included in the calculation of the power control parameters of the unicast service, the SPS data blocks of the target groupcast service must be included in the calculation of the power control parameters of the target groupcast service, i.e., n HARQ-ACK,TB(G-RNTI(i))is equal to the sum of the number of HARQ-ACK sub-codebook bits fed back on one PUCCH corresponding to groupcast service (i) and the number of semi-persistent scheduling transmission blocks (i.e., the number of SPS data transmission blocks) of groupcast service (i), i.e.,
