[0032] 1) CG PUSCH

[0033] NR uplink supports semi-static periodic transmission mode, namely configured grant PUSCH transmission, which includes two types:

[0034] Type-1 CG: After the Radio Resource Control (RRC) configures the transmission parameters, they take effect without the need for Downlink Control Information (DCI) activation.

[0035] Type-2 CG: After RRC configures the transmission parameters, they need to be activated by DCI to take effect.

[0036] CG supports symbol-level cycles of 2 symbols / 7 symbols and slot-level cycles of {1, 2, 4, 5, 8, 10, 16, 20, 32, 40...}. In NR R15 / 16 / 17, PUSCH is transmitted once in one CG cycle (i.e., there is only one PUSCH occasion).

[0037] The number of the HARQ process carried by the CG PUSCH is determined according to one of the following two formulas based on the first time domain symbol source occupied by the current CG PUSCH:

[0038] HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes;

[0039] HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes+harq-ProcID-Offset2;

[0040] where CURRENT_symbol=(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slot number in the frame×numberOfSymbolsPerSlot+symbol number in the slot), and numberOfSlotsPerFrame and numberOfSymbolsPerSlot refer to the number of consecutive slots per frame and the number of consecutive symbols per slot, respectively as specified in TS 38.211.

[0041] 2) CG-UCI

[0042] NR introduces CG uplink control information (UCI) to support the transmission of CG PUSCH on unlicensed bands. The HARQ process number carried by CG PUSCH transmitted on unlicensed bands is no longer determined based on the occupied time domain self-resources. The UE embeds CG-UCI information in the transmitted CG PUSCH to inform the base station of the HARQ process number, redundancy version information and new data indication information carried by the current CG PUSCH, as shown in the following Table 1:

[0043] Table 1

[0044]

[0045] Among them, the last item is used to indicate whether the subsequent resources of the channel occupancy time (COT) where the current CG PUSCH is located can be shared for downlink transmission.

[0046] 3) Extended Reality (XR)

[0047] At the 3GPP RAN#88e meeting, a research project titled "eXtended Reality (XR) and cloud game (CG) evaluations for NR" was approved. The project covers services such as augmented reality (AR), virtual reality (VR), and cloud gaming. A key XR / CG service is video streaming, with an arrival rate (measured in frames per second) of 30, 60, 90, or 120 fps. The corresponding video stream periods are {33.33ms, 16.67ms, 11.11ms, and 8.33ms}.

[0048] XR data features variable packet sizes with a large average. For example, in an AR / VR system with a 100 Mbps data rate, the average uplink packet size is 20,833 bytes, the maximum is 31,250 bytes, and the minimum is 10,417 bytes. This means that the size of the packet to be transmitted in each cycle is between [10,417 bytes and 31,250 bytes]. In a real-world system with 100 Mbps bandwidth, transmitting a 20,833-byte packet requires approximately four time slots of transmission resources.

[0049] Currently, 3GPP supports configuring multiple PUSCH occasions within a CG cycle for transmitting large XR data packets. Furthermore, when the data volume within a cycle is relatively small and does not require the use of all pre-configured PUSCH occasions, the UE can dynamically notify the base station of unused PUSCH occasions for the week. The base station can then reallocate the unused PUSCH occasions to other UEs for data transmission, thereby improving system efficiency.

[0050] When multiple PUSCH occasions are configured within a period, if the existing CG PUSCH operating mechanism on the licensed carrier is used (i.e., the formula HARQ Process ID = [floor(CURRENT_symbol / periodicity)] modulo nrofHARQ-Processes), then the current symbol corresponding to multiple PUSCH occasions within a period is the same after dividing by the period and rounding, resulting in consecutive PUSCH occasions corresponding to the same HARQ process number. Referring to FIG2 , which illustrates a transmission period diagram involved in this application, for example, if Occasion 1 carries HARQ Process X, Occasion 2 immediately reuses Process X, and new data is loaded into the buffer of Process X, the data transmitted in Occasion 1 is cleared, and the data transmitted in Occasion 1 cannot support HARQ retransmission.

[0051] The solution shown in the embodiment of the present application provides a solution for determining the HARQ processes of multiple PUSCHs, which can avoid the failure of MAC PDU transmission in the HARQ process that needs to be used / reserved due to adjacent or similar PUSCHs using the same HARQ process, thereby improving transmission efficiency.

[0052] This solution is applicable to the case of CG transmission, and may also be applicable to the case of dynamic uplink grant (Dynamic Uplink Grant, DG) transmission, and may also be applicable to the case of DG+CG transmission.

[0053] For example, there are multiple CG transmission opportunities or multiple CG PUSCHs in one CG cycle.

[0054] For example, a CG period has one or more CG transmission opportunities or CG PUSCHs. Also, there are one or more CG configurations, and different CG configurations correspond to different CG indexes.

[0055] For example, multiple DG PUSCH transmissions are scheduled within a period of time or in one DCI.

[0056] For example, within a period of time, there is a DCI that schedules one or more DG PUSCH transmissions and activates or indicates one or more CG PUSCH transmissions. Optionally, the period of time is not related to the CG period. Optionally, the period of time can be one or more CG periods.

[0057] For example, within a period of time, there are one or more CG PUSCH transmissions, and at the same time, DCI schedules one or more DG PUSCH transmissions. Optionally, the period of time is not related to the CG period. Optionally, the period of time can be one or more CG periods.

[0058] For example, a DCI schedules one or more DG PUSCH transmissions and activates or indicates one or more CG PUSCH transmissions. Optionally, the activated or indicated CG PUSCH may be for one or more CG periods.

[0059] For example, there are one or more CG PUSCH transmissions, and the DCI schedules one or more DG PUSCH transmissions. Optionally, the one or more CG PUSCHs may be of one or more CG periods. Optionally, the one or more CG PUSCHs may be of the same CG index or of different CG indices.

[0060] Please refer to Figure 3, which shows a flow chart of a HARQ process processing method provided by an embodiment of the present application. The method can be performed by a terminal device, wherein the terminal device can be the terminal device 120 or the terminal device 130 in the network architecture shown in Figure 1. The method may include the following steps:

[0061] Step 301: Determine a hybrid automatic repeat request HARQ process of at least one PUSCH among a plurality of physical uplink shared channels PUSCH.

[0062] Among the process numbers of the multiple PUSCH HARQ processes, at least one process number is different from the other process numbers.

[0063] Alternatively, among the process numbers of the multiple PUSCH HARQ processes, at least one process number is the same as the other process numbers.

[0064] To sum up, for multiple PUSCHs, the terminal device can determine the HARQ process of at least one PUSCH to control the process numbers of the HARQ processes of multiple PUSCHs, thereby avoiding the failure of MAC PDU transmission in the HARQ process that needs to be used / reserved due to the use of the same HARQ process by adjacent or similar PUSCHs, thereby improving transmission efficiency.

[0065] Please refer to Figure 4, which shows a flow chart of a HARQ process processing method provided by an embodiment of the present application. The method can be interactively executed by a terminal device and a network-side device; wherein the terminal device and the network-side device can be the network-side device 110 and the terminal device 120 (or the terminal device 130) in the network architecture shown in Figure 1. As shown in Figure 4, the method can include the following steps:

[0066] Step 401: The network side device sends configuration information to the terminal device; the terminal device receives the configuration information.

[0075] In some embodiments, the configuration information is configured via a radio resource control (RRC) reconfiguration message.

[0076] For example, the above configuration information is configured through RRC reconfiguration.

[0077] For example, the configuration information includes available UL resources within a period of time. Optionally, the available UL resources include multiple UL resources. Optionally, the configuration information includes CG configuration. Optionally, a CG period of the CG configuration includes one or more CG PUSCH occasions.

[0078] For example, the above configuration information includes available HARQ processes or HARQ process ranges. Optionally, it includes the number of HARQ processes and / or HARQ process offsets. Optionally, the above HARQ process or HARQ process range, or the number of HARQ processes and / or HARQ process offsets, are for all CG occasions of the above UL resource configuration (such as CG), or for specific CG occasions of each cycle of the above UL resource configuration (such as CG) (such as the first CG occasion of each CG cycle).

[0079] Step 402: The network side device sends first indication information to the terminal device; the terminal device receives the first indication information.

[0080] Here, step 402 is an optional step.

[0081] In some embodiments, the first indication information is carried by a radio resource control RRC message, a medium access control MAC control element CE, or downlink control information DCI.

[0082] Step 403: The terminal device determines the HARQ process of at least one PUSCH among the multiple PUSCHs according to the above configuration information and / or the first indication information.

[0083] Optionally, among the process numbers of the multiple PUSCH HARQ processes, at least one process number is different from the other process numbers.

[0084] Alternatively, among the process numbers of the multiple PUSCH HARQ processes, at least one process number is the same as the other process numbers.

[0085] In some embodiments, determining a hybrid automatic repeat request (HARQ) process for at least one PUSCH among a plurality of physical uplink shared channels (PUSCHs) includes:

[0086] In a case where the multiple PUSCHs include at least two CG resources and / or DG resources belonging to the same period, or in a case where the multiple PUSCHs include at least two CG resources and / or DG resources within a specified length time period, the HARQ process of at least one PUSCH among the multiple PUSCHs is determined.

[0087] Alternatively, the terminal device determines the HARQ process of at least one PUSCH among the multiple PUSCHs in the following circumstances:

[0089] In an embodiment of the present application, when multiple CG resources and / or DG resources are included in a cycle, or when multiple CG resources and / or DG resources are included in a period of time, the transmission interval of the multiple CG resources and / or DG resources is small, and two PUSCHs may use the same HARQ process, resulting in the failure of MAC PDU transmission in the HARQ process that needs to be used / reserved. At this time, the terminal device can comprehensively determine the HARQ process of at least one PUSCH in the HARQ processes of multiple CG resources and / or DG resources to avoid the failure of MAC PDU transmission in the HARQ process that needs to be used / reserved due to two PUSCHs using the same HARQ process in the HARQ processes of multiple CG resources and / or DG resources.

[0198] Example 1

[0199] Based on the scheme shown in Figure 3 or Figure 4 above, in Example 1, the terminal device can determine the HARQ process or HARQ process number (HARQ Process Identifier, HPI) corresponding to / available at least one CG PSUCH according to the first parameter when there are multiple CG PUSCH resources.

[0200] Among them, the first parameter is used to determine the HARQ process interval / offset of multiple CG PUSCHs, or to determine the HARQ process numbers of multiple CG PUSCHs, or to indicate the interval / offset of the HARQ process numbers of other CG PUSCHs for a specific PUSCH (such as the first CG PUSCH), or to indicate the interval / offset of the HARQ process numbers of the next CG PUSCH for a specific PUSCH (such as the previous CG PUSCH, or the first X CG PUSCHs). The first parameter can be a value, a value list, or multiple sets of value lists. The first parameter can be predefined or network configured (such as RRC). The value list is a 1-to-1 mapping between CG PUSCH occasion and HARQ process interval / offset.

[0201] The specific implementation method can be as follows:

[0202] Step 1: The base station sends configuration information to the UE. The configuration information is used for CG transmission or HARQ process determination. Optionally, it includes at least one of the following:

[0203] a) The above configuration information is configured through RRC reconfiguration.

[0204] b) The above configuration information includes available UL resources within a period of time. Optionally, the available UL resources include multiple UL resources. Optionally, the above configuration information includes CG configuration. Optionally, a CG period of the CG configuration includes one or more CG PUSCH occasions.

[0205] c) The above configuration information includes the available HARQ process or HARQ process range. Optionally, it includes the number of HARQ processes and / or HARQ process offset. Optionally, the above HARQ process or HARQ process range, or the number of HARQ processes and / or HARQ process offset, is for all CG occasions of the above UL resource configuration (such as CG), or for a specific CG occasion of each cycle of the above UL resource configuration (such as CG) (such as the first CG occasion of each CG cycle).

[0206] d) According to the above configuration information, or the first indication information, the intervals / offsets between the HARQ processes of multiple CG occasions, or a period of CG occasions are determined to be the same or different.

[0207] e) The configuration information, or the first indication information, indicates a first parameter. Optionally, the first parameter may be predefined. Optionally, the first indication information may be carried via RRC / MAC CE / DCI.

[0208] 1) Optionally, the first parameter is used to indicate the HARQ process or HARQ process usage range of other CG occasions other than the specific CG occasion of each cycle of the UL resource configuration (such as CG). Optionally, the HARQ process or HARQ process usage range can be the HARQ process number and / or offset. For example, the specific CG occasion is the first CG occasion of the current CG cycle or each CG cycle.

[0209] 2) Optionally, the first parameter is used to determine the HARQ process interval / offset of multiple CG PUSCHs, or to determine the HARQ process numbers of multiple CG PUSCHs, or to indicate the interval / offset of the HARQ process numbers of other CG PUSCHs for a specific PUSCH (such as the first CG PUSCH), or to indicate the interval / offset of the HARQ process numbers of the subsequent CG PUSCH for a specific PUSCH (such as the previous CG PUSCH, or the first X CG PUSCHs).

[0210] 3) Optionally, the first parameter can be a value.

[0211] For example, the first parameter is A. Assume that there are three CG occasions in a CG cycle. The HARQ process of the first CG occasion is K (as calculated using the HARQ process calculation formula, or directly indicated by the network), and the HARQ process numbers of the two CG occasions after the first CG occasion are K+A and K+2A, respectively.

[0212] For example, the first parameter gives the HARQ process number of the first PUSCH (called PUSCH M) other than a specific CG PUSCH (such as the first CG PUSCH, called PUSCH A), or the HARQ process interval / offset of the above-mentioned PUSCH M for a specific CG PUSCH. The HARQ process offset between other CG PUSCHs, and between other CG PUSCHs and PUSCH M is the same value (the above-mentioned value can be indicated by the network (such as RRC / MAC CE / DCI) or predefined). Optionally, the HARQ process number of a specific PUSCH (such as the first CG PUSCH, or PUSCH A) is calculated according to the HARQ process calculation formula, or is indicated by the network (RRC / MAC CE / DCI). As an implementation method, assume that the first parameter value is M and the HARQ offset between PUSCHs is B. Assume that a CG period has 4 CG occasions. The HARQ process of the first CG occasion of a period is K. The numbers of all CG occasion HARQ processes in this period are K, K+M, K+M+B, and K+M+2B. Alternatively, the numbers of all CG occasion HARQ processes in this period are K, M, M+B, and M+2B.

[0213] 4) Optional, the first parameter is a list of values.

[0214] Optionally, the above value list is a 1-to-1 mapping between CG PUSCH occasion and HARQ process interval / offset.

[0215] For example, the first parameter is A, B, or C. Assume that a CG cycle has four CG occasions. The HARQ process of the first CG occasion is K (as calculated using the HARQ process calculation formula or directly indicated by the network), and the HARQ process numbers of the two CG occasions after the first CG occasion are K+A, K+B, and K+C, respectively.

[0216] For example, the first parameter takes values ​​of A, B, and C. Assume that a CG cycle has four CG occasions. The HARQ process of the first CG occasion is K (as calculated using the HARQ process calculation formula, or directly indicated by the network), and the HARQ process numbers of the two CG occasions after the first CG occasion are K+A, K+A+B, and K+A+B+C, respectively.

[0217] For example, the first parameter is A, B, or C. Assume that a CG cycle has four CG occasions. The HARQ process of the first CG occasion is K (as calculated using the HARQ process calculation formula or directly indicated by the network), and the HARQ process numbers of the two CG occasions after the first CG occasion are A, B, and C, respectively.

[0218] For example, the first parameter takes values ​​of A, B, C, and D. Assume that there are four CG occasions in a CG cycle. The HARQ process numbers of all CG occasions are A, B, C, and D respectively.

[0219] 5) Optional, the first parameter is a list of values.

[0220] Optionally, the above value list identifies multiple values, and different values ​​are for different intervals / offsets between HARQ processes of CG occasion.

[0221] Optional. Different values ​​correspond to different indexes.

[0222] Furthermore, the network instructs the user via DCI / MAC CE which value in the above value list to activate or use, or instructs the user to deactivate or not use at least one value in the above value list.

[0223] For example, the first parameter takes values ​​of A, B, or C. The network instructs the UE to use a HARQ offset value of B. Assuming that a CG cycle has four CG occasions, the HARQ process for the first CG occasion is K (as calculated using the HARQ process calculation formula or directly indicated by the network), and the HARQ process numbers for the two CG occasions following the first CG occasion are K+B and K+2B, respectively.

[0224] 6) Optionally, the first parameter is a list of multiple values.

[0225] Optionally, the above multiple sets of value lists and different rounding lists are used to identify different intervals / offsets between HARQ processes for CG occasions.

[0226] Optional. Different value lists correspond to different value list indexes.

[0227] Furthermore, the network instructs the user via DCI / MAC CE which value list to activate or use, or instructs the user to deactivate or not use one or more value lists. Optionally, a value list index is used to indicate the above information.

[0228] Optional. Each value list is a 1-to-1 mapping between CG PUSCH occasion and HARQ process interval / offset.

[0229] For example, the first parameter value is index1: {A, B, C}, index2: {D, E, F}. Assume that there are 4 CG occasions in a CG cycle. The DCI instructs the UE to use the value list of index2. The HARQ process of the first CG occasion is K (as calculated using the HARQ process calculation formula, or directly indicated by the network), and the HARQ process numbers of the two CG occasions after the first CG occasion are K+D, K+E, and K+F, respectively.

[0230] For example, the first parameter value is index1: {A, B, C}, index2: {D, E, F}. Assume that there are 4 CG occasions in a CG cycle. The DCI instructs the UE to use the value list of index2. The HARQ process of the first CG occasion is K (as calculated using the HARQ process calculation formula, or directly indicated by the network), and the HARQ process numbers of the two CG occasions after the first CG occasion are K+D, K+D+E, and K+D+E+F respectively.

[0231] Step 2: The UE determines the HARQ process number based on the configuration and / or indication information in step 1, or determines the HARQ process number of at least one CG occasion in one / each CG period, or determines the HARQ process number of multiple UL transmission occasions within a period of time. Optionally, at least one of the following is included:

[0232] a) When there is more than one CG resource in a CG period, the UE uses the above-mentioned first parameter, or uses the HARQ process calculation formula (defined in the existing 38321) + the first parameter, or uses the first HARQ process calculation formula, or uses the first HARQ process calculation formula + the first parameter to determine the HARQ process number of the CG occasion.

[0233] b) The above HARQ process number is determined in MAC execution.

[0234] c) The HARQ process number of the first CG occasion in each cycle is determined using the existing HARQ process calculation formula (defined in existing 38321). Alternatively, it may be calculated according to the method described in Example 2. Alternatively, it may be determined based on the existing HARQ process calculation formula (defined in existing 38321) plus the first parameter. Alternatively, it may be determined based on the first parameter.

[0235] d) The HARQ process number of all CG resources can be determined using the existing HARQ process calculation formula (defined in existing 38321), the first HARQ process calculation formula, and at least one of the first parameters.

[0236] e) The HARQ process number of at least one CG occasion of the above-mentioned one / each CG period determined by the UE, or the HARQ process number of multiple UL transmission occasions within a period of time, the interval / offset between these process numbers may be the same or different.

[0237] f) In the case of determining the HARQ process of at least one CG occasion according to the first parameter, a modulo operation needs to be performed on the obtained HARQ process number, or a modulo operation is not performed.

[0238] For example:

[0239] -Use this HARQ process calculation formula to calculate the HARQ process number of the first CG occasion in a period.

[0240] -HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes.

[0241] -This cycle has 2 CG occasions, the first parameter is A.

[0242] The HARQ process ID for the second CG occasion of the period is HARQ Process ID = [floor(CURRENT_symbol / periodicity)] modulo nrofHARQ-Processes + A. (The process ID may then be further moduloed, or not moduloed. Optionally, it may be moduloed with respect to nrofHARQ-Processes.) Alternatively, HARQ Process ID = [floor(CURRENT_symbol / periodicity) + A] modulo nrofHARQ-Processes. Alternatively, HARQ Process ID = {[floor(CURRENT_symbol / periodicity)] modulo nrofHARQ-Processes + A} modulo nrofHARQ-Processes.

[0243] Please refer to Figure 5, which shows a schematic diagram of HARQ process numbers according to an exemplary embodiment of the present application. As shown in Figure 5, a period T includes at least three CG / DG opportunities, and the HARQ process numbers of the three CG / DG opportunities increase sequentially.

[0244] Through the scheme shown in the embodiment of the present application, when there are multiple CG PUSCH transmission resources in a CG period, or when there are multiple PUSCH transmission resources within a period of time, a method for determining the HARQ process number of each PUSCH resource is provided. This is used to avoid the problem of using the above HARQ process when the data in a certain HARQ process has not been successfully transmitted or needs to be saved, resulting in the corresponding MAC PDU flush. The above embodiment 1 can be used alone or in combination with the following embodiment 2.

[0245] Example 2

[0246] Based on the solution shown in FIG. 3 or FIG. 4 above, in Example 2, the terminal device can determine the HARQ process or HARQ process number of a specific first CG PUSCH (which can be the above-mentioned specific PUSCH) when there are multiple CG PUSCH resources.

[0247] For example, the UE may determine the HARQ process or HARQ process number of the first CG PUSCH using the first HARQ process calculation formula, or determine the HARQ process or HARQ process number of the first CG PUSCH based on the second factor. The second factor may be indicated or configured by the network (RRC / MAC CE / DCI) or determined by the UE.

[0248] The specific implementation method can be as follows:

[0249] Step 1: The base station sends configuration information to the UE. The configuration information is used for CG transmission or HARQ process determination. Optionally, it includes at least one of the following:

Optionally, the above HARQ process or HARQ process range or the number of HARQ processes and / or HARQ process offset is for all CG occasions of the above UL resource configuration (such as CG), or for a specific CG occasion of each cycle of the above UL resource configuration (such as CG) (such as the first CG occasion of each CG cycle).

[0253] d) The above-mentioned configuration information, or the second indication information, indicates the second factor, or instructs the UE to use the calculation formula of the first HARQ process. Optionally, the above-mentioned second indication information, or the second factor, or the indication information instructing the UE to use the calculation formula of the first HARQ process, may be carried via RRC / MAC CE / DCI. Optionally, the second indication information may be related to the second factor. Optionally, the second factor may be predefined, or indicated by the network, or preconfigured by the network, or enabled / disabled by the network. Optionally, the second indication information, or the indication information instructing the UE to use the calculation formula of the first HARQ process, may be predefined, or indicated by the network, or preconfigured by the network, or enabled / disabled by the network.

[0255] Optionally, the second indication information or the second factor is related to at least one of the following: service characteristics, data volume size, data volume change, number of CG configurations (or CG index), number of resources, resource configuration period, number of resources in a period, resource spacing, number of periods (or the current period number), (maximum) number of CG resources in a period, number of available HARQ processes, HARQ process offset, maximum number of HARQ processes, and HARQ interval (offset) between HARQ of resources in a period.

[0270] For example: HARQ Process ID = {{[floor(CURRENT_symbol / periodicity)]}*N} modulo nrofHARQ-Processes. Optionally, N is the second factor.

[0271] For example: HARQ Process ID = {{[floor(CURRENT_symbol / periodicity)] modulo nrofHARQ-Processes}*N} modulo nrofHARQ-Processes. Optionally, N is the second factor.

[0272] For example: HARQ Process ID = {{[floor(CURRENT_symbol / periodicity)] modulo nrofHARQ-Processes+harq-ProcID-Offset2}*N} modulo nrofHARQ-Processes. Optionally, N is the second factor.

[0273] For example: HARQ Process ID = {{[floor(CURRENT_symbol / periodicity)]+harq-ProcID-Offset2}*N} modulo nrofHARQ-Processes. Optionally, N is the second factor.

[0274] e) The UE determines the HARQ process or HARQ process number of the first CG PUSCH.

[0275] Optionally, the UE determines the HARQ process or HARQ process number of the first CG PUSCH based on the second factor.

[0278] Optionally, the UE uses an existing HARQ process calculation formula to determine the HARQ process or HARQ process number of the first CG PUSCH, which may be as follows:

[0279] Assumption: HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes; or, HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes+harq-ProcID-Offset; or, HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes; or, HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes+harq-ProcID-Offset2. Alternatively, assume that HARQ Process ID = {{[floor(CURRENT_symbol / periodicity)]+harq-ProcID-Offset2}*N}modulo nrofHARQ-Processes. According to one or at least one of the above formulas, the HARQ process number of a certain CG period is calculated to be M. Then, the HARQ process number of the first CG occasion of the period is: M*N, where N is the second indication information or the second factor (optionally, N is the (maximum) number of occasions allocated to a CG period. For example, the above (maximum) number is N=4, and the determined HARQ process numbers of the first occasion of each CG period are 0, 4, 8, 12...). Optionally, it is necessary to take a modulo on M*N, for example, {M*N}modulo nrofHARQ-Processes, to obtain the HARQ process number of the first occasion of each CG period.

[0280] Assumption: HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes; or, HARQ Process ID=[floor(CURRENT_slot×10 / (numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes+harq-ProcID-Offset; or, HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes; or, HARQ Process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes+harq-ProcID-Offset2. Alternatively, assume that HARQ Process ID = {{[floor(CURRENT_symbol / periodicity)]+harq-ProcID-Offset2}*N}modulo nrofHARQ-Processes. According to one or at least one of the above formulas, the HARQ process number of a certain CG cycle is calculated to be M. Then, the HARQ process number of the first CG occasion of the cycle is: M+K*N, where N is the second indication information or the second factor (optionally, N is the (maximum) number of occasions allocated to a CG cycle - 1, or N is the resource spacing.). K is the cycle index of the above cycle, or K = L (the current cycle belongs to the Lth CG cycle) - 1. For example, N = 3, and the determined HARQ process numbers of the first occasion of each CG cycle are 0, 4, 8, 12...). Optionally, it is necessary to take the modulus of M+K*N, for example, {M+K*N}modulo nrofHARQ-Processes, to obtain the HARQ process number of the first occasion of each CG cycle.

[0281] f) The HARQ process number of other occasions in the cycle is the HARQ process number of the first CG PUSCH of the cycle + (K-1)*1. K is the PUSCH number of the cycle. Alternatively, the HARQ process number of other occasions in the cycle is the HARQ process number of the first CG PUSCH of the cycle + (K-1)*Q (K is the PUSCH number of the cycle, and Q can be a fixed value, a predefined value, or a network indication value). Alternatively, the HARQ process number of other occasions in the cycle is the HARQ process number of the first CG PUSCH of the cycle + 1. Alternatively, the HARQ process number of other occasions in the cycle is the HARQ process number of the first CG PUSCH of the cycle + Q (Q can be a fixed value, a predefined value, or a network indication value). Alternatively, for other occasions within the cycle, the HARQ process number of each PUSCH is the HARQ process number of the previous PUSCH of this PUSCH in the cycle + 1. Alternatively, for other occasions within the cycle, the HARQ process number of each PUSCH is the HARQ process number of the previous PUSCH of this PUSCH in the cycle + Q (where Q can be a fixed value, a predefined value, or a network indication value). Alternatively, the HARQ process number of other occasions within the cycle is calculated according to the method of embodiment 1.
