Description

Technical Field

[0001] The present invention relates to the technical field of mobile communications, and in particular to a transmission method, a receiving method, a terminal and a base station of a physical uplink shared channel. Background Art

[0002] In the prior art, in the physical uplink shared channel (PUSCH) scheduling method, the time domain resource information of the PUSCH is indicated by the downlink control information (DCI), specifically including the slot offset K2, the start symbol and the length, such as Figure 1 As shown. The DCI indicates the hybrid automatic repeat request process number (HARQ process number) and the new data indication (New data indication). When the HARQ process number is the same and the NDI is not flipped, it means that the scheduled data is retransmission. In addition, the number of PUSCH repetitions pusch-AggregationFactor (2, 4, 8) is configured through the Radio Resource Control (RRC) signaling, or when the DCI indicates the PUSCH time domain resource information, the number of repetitions is indicated. In addition, the redundancy version (RV) mode of PUSCH is indicated by DCI, and the specific value can be any of the following: 0231, 2310, 3102, 1023. For example, Figure 1 The RV in is "0231", indicating that the redundancy version modes of the four adjacent PUSCHs are RV0, RV2, RV3 and RV1 respectively, and the meanings of "2310" and so on are similar.

[0003] In the prior art, when performing sequential scheduling of PUSCH, if the HARQ process numbers are the same, the DCI scheduling of the PUSCH with the same HARQ process number can be sent only after the previous PUSCH transmission. Figure 2 An example of the above scheduling is given, in which DCI-0 and DCI-1 both schedule PUSCH with HARQ process number 1, and DCI-1 scheduling the next PUSCH with the same HARQ process number is sent after the PUSCH scheduled by DCI-0 is transmitted.

[0004] The configuration method of the transmit power control (Transmit Power Control, TPC) command in PUSCH power control is: determine the closed-loop power control adjustment amount of PUSCH through the TPC command (TPC command) indicated in the DCI. Among them, DCI 0_0 / DCI 0_1 can indicate the TPC command. DCI 2_2 can indicate the TPC group command (group commonTPC), which includes multiple block numbers (block), such as block number 1, block number 2,…, blocknumber N, each block number contains 3 bits, 1 bit of closeloop and 2 bits of TPC, respectively. In addition, the tpc-Index is configured through RRC to indicate which block is used to receive this DCI. When the terminal (UE) receives multiple DCIs indicating TPC, the UE will sum the values ​​of the TPC indications in the received multiple DCIs when sending PUSCH and apply them to the closed-loop power control of PUSCH.

[0005] like Figure 3 As shown, in the multi-transmitting and receiving node (Multi-TRP) scenario, the control resource sets (Control Resource Set, CORESET) of two TRPs are associated with different control resource set pool indexes (coresetPoolIndex). The terminal can determine which TRP the PDCCH carried on the CORESET comes from by judging the coresetPoolIndex associated with the CORESET.

[0006] For example, TRP0 is associated with coresetPoolIndex = 0, and TRP1 is associated with coresetPoolIndex = 1. The terminal sends one PUSCH, and both TRPs can receive it.

[0007] In order to improve the reliability of PUSCH in Multi-TRP scenario, PUSCH repetition is considered to be introduced. Currently, the existing repetition transmission scheme has no specific implementation scheme for PUSCH repetition in Multi-TRP scenario. Summary of the invention

[0108] See also Figure 4 , Figure 4 A block diagram of a wireless communication system applicable to an embodiment of the present invention is shown. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a user terminal or user equipment (UE, User Equipment), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 can be a base station and / or a core network element, wherein the above-mentioned base station can be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or other access point, etc.), wherein the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0109] The base station can communicate with the terminal 11 under the control of a base station controller, and in various examples, the base station controller can be part of the core network or certain base stations. Some base stations can communicate control information or user data with the core network via a backhaul. In some examples, some of these base stations can communicate with each other directly or indirectly via a backhaul link, which can be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers at the same time. For example, each communication link can be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0110] The base station can communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​the access point can be divided into sectors that constitute only a portion of the coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or micro-micro base stations). The base station may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base station may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0111] The communication link in the wireless communication system may include an uplink for carrying an uplink (UL) transmission (e.g., from the terminal 11 to the network device 12), or a downlink for carrying a downlink (DL) transmission (e.g., from the network device 12 to the terminal 11). UL transmission may also be referred to as reverse link transmission, and DL transmission may also be referred to as forward link transmission. Downlink transmission may be performed using a licensed frequency band, an unlicensed frequency band, or both. Similarly, uplink transmission may be performed using a licensed frequency band, an unlicensed frequency band, or both.

[0112] As described in the background technology, the prior art does not have a specific implementation solution for PUSCH repeated transmission in Multi-TRP scenarios. For example, there is no specific description on how to schedule 1 PUSCH for repeated transmission through 2 different DCIs, and how to determine the redundant version (RV) mode, transmission time domain location, and power control parameters during PUSCH repeated transmission.

[0113] In order to solve at least one of the above problems, an embodiment of the present invention provides a transmission method of a physical uplink shared channel (PUSCH), which realizes the repeated transmission of the PUSCH channel of 2 TRPs. In addition, an embodiment of the present invention also provides a specific implementation solution for the RV mode, transmission time domain position, and power control parameters during repeated transmission of PUSCH.

[0114] Please refer to Figure 5 The physical uplink shared channel transmission method provided in the embodiment of the present invention, when applied to the terminal side, includes:

[0115] Step 51: The terminal repeatedly transmits the PUSCH scheduled by the first DCI and the second DCI.

[0116] Here, the first parameters indicated by the first DCI and the second DCI are the same, and the first parameters include at least one of a redundancy version mode, a HARQ process number, and a new data indication.

[0117] Through the above steps, the embodiment of the present invention repeatedly transmits the PUSCH scheduled by the first DCI and the second DCI, thereby realizing the repeated transmission of the PUSCH channel of 2 TRPs.

[0118] Before the above step 51, the terminal may also receive the first DCI and the second DCI.

[0119] Preferably, the CORESETs carrying the first DCI and the second DCI are respectively associated with different high-level parameter control resource set pool indexes. That is, the first DCI and the second DCI are associated with different control resource set pool indexes (coresetPoolIndex).

[0120] Specifically, the embodiment of the present invention can take the PUSCH transmission opportunities scheduled by the first DCI and the second DCI as a set, and then determine the redundant version corresponding to each PUSCH transmission opportunity in the set. Furthermore, according to the redundant version corresponding to each determined PUSCH transmission opportunity, the PUSCH can be repeatedly transmitted at each PUSCH transmission opportunity.

[0121] When determining the redundancy version corresponding to a certain PUSCH transmission opportunity, specifically, according to the position of the PUSCH transmission opportunity in the set, the redundancy version corresponding to the PUSCH transmission opportunity is determined from the redundancy version mode. Here, the redundancy version mode is indicated in the first DCI or the second DCI, and preferably, the redundancy version mode indicated by the first DCI and the second DCI in the embodiment of the present invention is the same.

[0122] For example, when the redundant version mode is 0231, the redundant version corresponding to the first PUSCH transmission set in the set is RV0, the redundant version corresponding to the second PUSCH transmission set in the set is RV2, the redundant version corresponding to the third PUSCH transmission set in the set is RV3, the redundant version corresponding to the fourth PUSCH transmission set in the set is RV1, and so on.

[0123] In an embodiment of the present invention, it is assumed that the first DCI schedules N PUSCH transmission opportunities, and the second DCI schedules M PUSCH transmission opportunities; the redundancy version mode includes Z redundancy versions. For example, the redundancy version mode is 0231, which includes 4 redundancy versions, namely RV0, RV2, RV3 and RV1. The N may be configured by the first DCI, a Medium Access Control (MAC) control element (CE) or a Radio Resource Control (RRC) message; the M may be configured by the second DCI, a MAC CE or an RRC message.

[0124] The mapping mode of the PUSCH transmission opportunity includes a sequential mapping mode and a cyclic mapping mode. In an embodiment of the present invention, the base station may pre-configure the terminal to adopt the sequential mapping mode or the cyclic mapping mode. For example, the base station may configure the above mode through an RRC message. The terminal determines the specific mode to be adopted according to the configuration message sent by the base station.

[0125] Among them, in the sequential mapping mode, the N PUSCH transmission opportunities scheduled by the first DCI are transmitted before the M PUSCH transmission opportunities scheduled by the second DCI. Of course, the N PUSCH transmission opportunities scheduled by the first DCI can also be transmitted after the M PUSCH transmission opportunities scheduled by the second DCI. That is to say, in the sequential mapping mode, the PUSCHs scheduled by the two DCIs are transmitted one after another.

[0126] Preferably, in the sequential mapping mode, the N PUSCH transmission opportunities scheduled by the first DCI are respectively located in N consecutive time slots; the M PUSCH transmission opportunities scheduled by the second DCI are respectively located in M ​​consecutive time slots. In the sequential mapping mode, two DCIs respectively schedule PUSCH for repeated transmission, and each DCI-scheduled PUSCH is repeatedly transmitted in N or M consecutive time slots, respectively, where N and M depend on the RRC message or DCI configuration.

[0127] In the cyclic mapping mode, the PUSCH transmission timing of the first DCI scheduling and the PUSCH transmission timing of the second DCI scheduling are transmitted alternately in the time domain. That is to say, after the PUSCH transmission timing of the first DCI scheduling: if the PUSCH transmission timing of the second DCI scheduling still exists, the PUSCH scheduled by the second DCI is transmitted; if the PUSCH transmission timing of the second DCI scheduling no longer exists, the PUSCH scheduled by the first DCI continues to be transmitted until all the PUSCH scheduled by the first DCI is transmitted. Similarly, after the PUSCH transmission timing of the second DCI scheduling: if the PUSCH transmission timing of the first DCI scheduling still exists, the PUSCH scheduled by the first DCI is transmitted; if the PUSCH transmission timing of the first DCI scheduling no longer exists, the PUSCH scheduled by the second DCI continues to be transmitted until all the PUSCH scheduled by the second DCI is transmitted.

[0128] Preferably, in the cyclic mapping mode, the N PUSCH transmission opportunities scheduled by the first DCI and the M PUSCH transmission opportunities scheduled by the second DCI are respectively located in consecutive N+M time slots. In the cyclic mapping mode, the two DCIs respectively schedule PUSCH for repeated transmission, and each DCI-scheduled PUSCH is repeatedly transmitted once every other time slot, for a total of N or M transmissions, where N and M depend on the RRC message or DCI configuration.

[0129] Several PUSCH redundancy version determination methods that can be used in embodiments of the present invention are provided below. In the following methods, the redundancy version mode, HARQ process number and new data indication indicated by the first DCI and the second DCI are the same. Assume that the redundancy version mode includes 4 redundancy versions, ie, Z=4.

[0130] Method 1:

[0131] In the method 1, the mapping mode of the PUSCH transmission opportunity is a sequential mapping mode. When determining the redundancy version corresponding to each PUSCH transmission opportunity from the redundancy version mode according to the position of each PUSCH transmission opportunity in the set:

[0132] For the i-th PUSCH transmission opportunity of the first DCI scheduling, performing a modulo Z operation on i to obtain a first remainder; and selecting a redundancy version corresponding to the PUSCH transmission opportunity from a redundancy version mode according to the first remainder;

[0133] For the j-th PUSCH transmission opportunity scheduled by the second DCI, performing a modulo Z operation on (N+j) to obtain a second remainder; and selecting a redundancy version corresponding to the PUSCH transmission opportunity from the redundancy version mode according to the second remainder;

[0134] The value range of i is 0 to N-1, and the value range of j is 0 to M-1.

[0135] For example, in the RV version determination method corresponding to N PUSCH transmission opportunities scheduled by the first DCI, the RV of the nth PUSCH transmission opportunity depends on nmod4. Among them, nmod4=0 corresponds to the first RV version indicated by the first DCI, nmod4=1 corresponds to the second RV version indicated by the first DCI, nmod4=2 corresponds to the third RV version indicated by the first DCI, and nmod4=3 corresponds to the fourth RV version indicated by the first DCI.

[0136] The RV version determination method corresponding to the M PUSCH transmission opportunities scheduled by the second DCI depends on the N PUSCHs scheduled by the first DCI. The RV of the mth PUSCH transmission opportunity depends on (m+N)mod4. Among them, (m+N)mod4=0 corresponds to the first RV version indicated by the first or second DCI, (m+N)mod4=1 corresponds to the second RV version indicated by the first or second DCI, (m+N)mod4=2 corresponds to the third RV version indicated by the first or second DCI, and (m+N)mod4=3 corresponds to the fourth RV version indicated by the first or second DCI.

[0137] Here, N and M depend on the RRC message or DCI configuration, and N and M can be the same. For example, if RRC configures 1 preset parameter X, then N=M=X or N=M=X / 2. Or the first DCI indicates N, and the second DCI indicates M. The value of n is 0, 1, 2, ..., N-1, and the value of m is 0, 1, 2, ..., M-1.

[0138] Example 1: Figure 6 As shown, the RV versions indicated in the first DCI and the second DCI are both {0231}, and the RRC configuration X=4. The first DCI schedules PUSCH repeated transmission N / 2=2 times, and the second DCI schedules PUSCH repeated transmission N / 2=2 times. Then the RV version of the 0th PUSCH transmission opportunity scheduled by the first DCI is 0, and the RV version of the 1st PUSCH transmission opportunity scheduled by the first DCI is 2; the RV version of the 0th PUSCH transmission opportunity scheduled by the second DCI is 3, and the RV version of the 1st PUSCH transmission opportunity scheduled by the second DCI is 1.

[0139] Example 2: The RV versions indicated in the first and second DCIs are both {0231}, the first DCI configuration N=2, and the second DCI configuration M=4. The first DCI schedules PUSCH repeated transmission N=2 times, and the second DCI schedules PUSCH repeated transmission M=4 times. Then the RV version of the 0th PUSCH transmission opportunity scheduled by the first DCI is 0, and the RV version of the 1st PUSCH transmission opportunity scheduled by the first DCI is 2; the RV version of the 0th PUSCH transmission opportunity scheduled by the second DCI is 3, the RV version of the 1st PUSCH transmission opportunity scheduled by the second DCI is 1, the RV version of the 2nd PUSCH transmission opportunity scheduled by the second DCI is 0, and the RV version of the 3rd PUSCH transmission opportunity scheduled by the second DCI is 2.

[0140] Method 2:

[0141] In this mode 2, the mapping mode of the PUSCH transmission opportunity is a cyclic mapping mode. Assume that the first PUSCH transmission opportunity scheduled by the first DCI is before the first PUSCH transmission opportunity scheduled by the second DCI. When determining the redundant version corresponding to each PUSCH transmission opportunity from the redundant version mode according to the position of each PUSCH transmission opportunity in the set:

[0142] When N=M: for the i-th PUSCH transmission opportunity scheduled by the first DCI, a third remainder is obtained by performing a modulo Z operation on 2i; and a redundant version corresponding to the PUSCH transmission opportunity is selected from the redundant version mode according to the third remainder; for the j-th PUSCH transmission opportunity scheduled by the second DCI, a fourth remainder is obtained by performing a modulo Z operation on 2j+1; and a redundant version corresponding to the PUSCH transmission opportunity is selected from the redundant version mode according to the fourth remainder;

[0143] When N>M: for the i-th PUSCH transmission opportunity scheduled by the first DCI, when i is less than or equal to M-1, perform a modulo Z operation on 2i, and when i is greater than M-1, perform a modulo Z operation on i+M to obtain a fifth remainder; according to the fifth remainder, select the redundant version corresponding to the PUSCH transmission opportunity from the redundant version mode; for the j-th PUSCH transmission opportunity scheduled by the second DCI, perform a modulo Z operation on 2j+1 to obtain a sixth remainder; according to the sixth remainder, select the redundant version corresponding to the PUSCH transmission opportunity from the redundant version mode;

[0144] When N < M: For the i-th PUSCH transmission occasion scheduled by the first DCI, perform a modulo-Z operation on 2i to obtain a seventh remainder; according to the seventh remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version patterns; for the j-th PUSCH transmission occasion scheduled by the second DCI, perform a modulo-Z operation on 2j when j is less than or equal to N - 1, and perform a modulo-Z operation on j + N when j is greater than N - 1 to obtain an eighth remainder; according to the eighth remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version patterns;

[0145] wherein, the value range of i is 0 to N - 1, and the value range of j is 0 to M - 1.

[0146] Here, N and M can depend on RRC messages or DCI configurations, and N and M can be the same. For example, if the RRC configures a preset parameter X, then N = M = X or N = M = X / 2. Or the first DCI indicates N, and the second DCI indicates M. n takes values of 0, 1, 2, …, N - 1, and m takes values of 0, 1, 2, …, M - 1.

[0147] When M = N,

[0148] a) Determination method of the RV versions corresponding to N PUSCH transmission occasions scheduled by the first DCI: The RV of the n-th PUSCH transmission occasion depends on (2*n) mod 4. (2*n) mod 4 = 0 corresponds to the first one in the RV versions indicated by the first DCI, (2*n) mod 4 = 1 corresponds to the second one in the RV versions indicated by the first DCI, (2*n) mod 4 = 2 corresponds to the third one in the RV versions indicated by the first DCI, and (2*n) mod 4 = 3 corresponds to the fourth one in the RV versions indicated by the first DCI.

[0149] b) Determination method of the RV versions corresponding to M PUSCH transmission occasions scheduled by the second DCI depends on the N PUSCHs scheduled by the first DCI: The RV of the m-th PUSCH transmission occasion depends on (2*m + 1) mod 4. (2*m + 1) mod 4 = 0 corresponds to the first one in the RV versions indicated by the first or second DCI, (2*m + 1) mod 4 = 1 corresponds to the second one in the RV versions indicated by the first or second DCI, (2*m + 1) mod 4 = 2 corresponds to the third one in the RV versions indicated by the first or second DCI, and (2*m + 1) mod 4 = 3 corresponds to the fourth one in the RV versions indicated by the first or second DCI.

[0150] When M < N,

[0151] a) The RV version determination method corresponding to the N PUSCH transmission opportunities scheduled by the first DCI, when n≤(M-1), the RV of the nth PUSCH transmission opportunity depends on (2*n)mod4: (2*n)mod4=0 corresponds to the first RV version indicated by the first DCI, (2*n)mod4=1 corresponds to the second RV version indicated by the first DCI, (2*n)mod4=2 corresponds to the third RV version indicated by the first DCI, and (2*n)mod4=3 corresponds to the fourth RV version indicated by the first DCI. When n>(M-1), the RV of the nth PUSCH transmission opportunity depends on (n+M)mod4: (n+M)mod4=0 corresponds to the first RV version indicated by the first DCI, (n+M)mod4=1 corresponds to the second RV version indicated by the first DCI, (n+M)mod4=2 corresponds to the third RV version indicated by the first DCI, and (n+M)mod4=3 corresponds to the fourth RV version indicated by the first DCI.

[0152] b) The RV version determination method corresponding to the M PUSCH transmission opportunities scheduled by the second DCI depends on the N PUSCHs scheduled by the first DCI. The RV of the mth PUSCH transmission opportunity depends on (2*m+1)mod4, (2*m+1)mod4=0 corresponds to the first RV version indicated by the first or second DCI, (2*m+1)mod4=1 corresponds to the second RV version indicated by the first or second DCI, (2*m+1)mod4=2 corresponds to the third RV version indicated by the first or second DCI, and (2*m+1)mod4=3 corresponds to the fourth RV version indicated by the first or second DCI.

[0153] When M>N,

[0154] a) The RV version determination method corresponding to the N PUSCH transmission opportunities scheduled by the first DCI, the RV of the nth PUSCH transmission opportunity depends on (2*n)mod4: (2*n)mod4=0 corresponds to the first RV version indicated by the first DCI, (2*n)mod4=1 corresponds to the second RV version indicated by the first DCI, (2*n)mod4=2 corresponds to the third RV version indicated by the first DCI, and (2*n)mod4=3 corresponds to the fourth RV version indicated by the first DCI.

[0155] b) The RV version determination method corresponding to the M PUSCH transmission opportunities scheduled by the second DCI depends on the N PUSCHs scheduled by the first DCI. When m≤(N-1), the RV of the mth PUSCH transmission opportunity depends on (2*m+1)mod4, (2*m+1)mod4=0 corresponds to the first RV version indicated by the first or second DCI, (2*m+1)mod4=1 corresponds to the second RV version indicated by the first or second DCI, (2*m+1)mod4=2 corresponds to the third RV version indicated by the first or second DCI, and (2*m+1)mod4=3 corresponds to the fourth RV version indicated by the first or second DCI. When m>(N-1), the RV of the nth PUSCH transmission opportunity depends on (m+N)mod4: (m+N)mod4=0 corresponds to the first RV version indicated by the first DCI, (m+N)mod4=1 corresponds to the second RV version indicated by the first DCI, (m+N)mod4=2 corresponds to the third RV version indicated by the first DCI, and (m+N)mod4=3 corresponds to the fourth RV version indicated by the first DCI.

[0156] Example 3: Figure 7 As shown, the RV versions indicated in the first and second DCIs are both {0231}, and the RRC configuration X=4. The first DCI schedules PUSCH repeated transmission N=X / 2=2 times, and the second DCI schedules PUSCH repeated transmission M=X / 2=2 times. Then the RV version of the 0th PUSCH transmission opportunity scheduled by the first DCI is 0, the RV version of the 0th PUSCH transmission opportunity scheduled by the second DCI is 2, the RV version of the 1st PUSCH transmission opportunity scheduled by the first DCI is 3, and the RV version of the 1st PUSCH transmission opportunity scheduled by the second DCI is 1.

[0157] Example 4: The RV versions indicated in the first and second DCIs are both {0231}, the first DCI configuration N=2, and the second DCI configuration M=4. The first DCI schedules PUSCH repeated transmission N=2 times, and the second DCI schedules PUSCH repeated transmission M=4 times. Then the RV version of the 0th PUSCH transmission opportunity scheduled by the first DCI is 0, the RV version of the 0th PUSCH transmission opportunity scheduled by the second DCI is 2, the RV version of the 1st PUSCH transmission opportunity scheduled by the first DCI is 3, the RV version of the 1st PUSCH transmission opportunity scheduled by the second DCI is 1, the RV version of the 2nd PUSCH transmission opportunity scheduled by the second DCI is 0, and the RV version of the 3rd PUSCH transmission opportunity scheduled by the second DCI is 2.

[0158] Method 3:

[0159] In this mode 3, the mapping mode of the PUSCH transmission opportunity is a sequential mapping mode or a cyclic mapping mode. When determining the redundancy version corresponding to each PUSCH transmission opportunity from the redundancy version mode according to the position of each PUSCH transmission opportunity in the set:

[0160] For the kth PUSCH transmission opportunity in the set, performing a modulo Z operation on k to obtain a ninth remainder; and selecting a redundancy version corresponding to the PUSCH transmission opportunity from a redundancy version mode according to the ninth remainder;

[0161] The value range of k is 0 to N+M-1.

[0162] Here, if Figure 8 As shown, the RV versions are mapped sequentially according to the time domain positions of the PUSCH transmission opportunities scheduled by two DCIs. For example, the RV of the nth PUSCH depends on nmod4, nmod4=0 corresponds to the first RV version indicated by the DCI, nmod4=1 corresponds to the second RV version indicated by the DCI, nmod4=2 corresponds to the third RV version indicated by the DCI, and nmod4=3 corresponds to the fourth RV version indicated by the DCI. Figure 8 The top row is the sequential mapping mode, and the bottom row is the cyclic mapping mode.

[0163] Here, n takes values ​​of 0, 1, 2, ..., N+M-1, and N and M depend on the RRC message or DCI configuration, and N and M can be the same. For example, if the RRC message configures 1 parameter X, then N = M = X or N = M = X / 2. Or the first DCI indicates N, and the second DCI indicates M.

[0164] In the sequential mapping mode, the embodiment of the present invention allows receiving a PUSCH transmission with the same HARQ process number scheduled by the second DCI when the PUSCH scheduled by the first DCI has not yet been transmitted. That is, before the above step 51, the terminal can also receive the first DCI and the second DCI, wherein the reception timing of the second DCI is earlier than the transmission timing of the PUSCH scheduled by the first DCI.

[0165] Optionally, in an embodiment of the present invention, the terminal performs closed-loop power control adjustment at the PUSCH transmission timing scheduled by the first DCI or the second DCI according to a transmission power control command indicated in the corresponding DCI.

[0166] Specifically, the transmission power control command indicated by the DCI with the associated control resource set pool index value of 0 is used for the closed-loop power control adjustment of the PUSCH scheduled by the DCI with the associated control resource set pool index value of 0. That is, the TPC command indicated in the DCI with the associated coresetPoolIndex=0 is used for the closed-loop power control adjustment of the PUSCH scheduled by the DCI with the associated coresetPoolIndex=0.

[0167] The transmission power control command indicated by the DCI with the associated control resource set pool index value of 1 is used for the closed-loop power control adjustment of the PUSCH scheduled by the DCI with the associated control resource set pool index value of 1. That is, the TPC command indicated in the DCI with the associated coresetPoolIndex=1 is used for the closed-loop power control adjustment of the PUSCH scheduled by the DCI with the associated coresetPoolIndex=1.

[0168] Optionally, in an embodiment of the present invention, the default spatial information and / or the default path loss reference signal of the PUSCH transmission timing scheduled by the first DCI or the second DCI refers to the quasi-co-location type (QCL-TypeD) of the control resource set with the minimum ID in the corresponding control resource set or the reference signal assumed by QCL.

[0169] Specifically, the default spatial information and / or default path loss reference signal of the PUSCH transmission opportunity scheduled by the DCI with the associated control resource set pool index value of 0 refers to the reference signal of the QCL-TypeD or QCL assumption of the smallest ID in the control resource set with the associated control resource set pool index value of 0. That is, the default spatial and default Pathloss RS of the PUSCH scheduled by the DCI with the associated coresetPoolIndex=0 refer to the reference signal of the QCL-TypeD or QCL assumption of the CORESET with the lowest ID number in the same coresetPoolIndex.

[0170] The default spatial information and / or default path loss reference signal of the PUSCH transmission opportunity scheduled by the DCI with the associated control resource set pool index value of 1 refers to the reference signal of the QCL-TypeD or QCL assumption of the smallest ID in the control resource set with the associated control resource set pool index value of 1. That is, the default spatial and default Pathloss RS of the PUSCH scheduled by the DCI with the associated coresetPoolIndex=1 refer to the reference signal of the QCL-TypeD or QCL assumption of the CORESET with the lowest ID number in the same coresetPoolIndex.

[0171] From the above, it can be seen that the above method provided by the embodiment of the present invention can determine the RV version, time domain position, TPC command, default spatial and default path loss RS when PUSCH is repeatedly transmitted in a Multi-TRP scenario, thereby improving the reliability of PUSCH transmission.

[0172] The above describes the transmission method of the physical uplink shared channel according to the embodiment of the present invention from the terminal side. The following describes it from the base station side.

[0173] Please refer to Fig. 9 The embodiment of the present invention provides a method for receiving a physical uplink shared channel, which is applied to a base station side and includes:

[0174] Step 91: The base station receives a PUSCH repeatedly transmitted by a terminal, wherein the repeatedly transmitted PUSCH is scheduled by the first DCI and the second DCI.

[0175] Here, the first parameters indicated by the first DCI and the second DCI are the same, and the first parameters include at least one of a redundancy version mode, a HARQ process number, and a new data indication.

[0176] Through the above steps, the base station of the embodiment of the present invention can receive the repeatedly transmitted PUSCH scheduled by the first DCI and the second DCI, thereby realizing the reception of the PUSCH channel of 2 TRPs.

[0177] Before the above step 91, a first DCI and a second DCI may also be received.

[0178] Preferably, the CORESETs carrying the first DCI and the second DCI are respectively associated with different high-level parameter control resource set pool indexes. That is, the first DCI and the second DCI are associated with different control resource set pool indexes (coresetPoolIndex).

[0179] In the embodiment of the present invention, the first TRP and the second TRP can be regarded as a component unit of the base station.

[0180] Specifically, in the above step 91, the base station can take the PUSCH transmission opportunities scheduled by the first DCI and the second DCI as a set, determine the redundant version corresponding to each PUSCH transmission opportunity in the set; and according to the determined redundant version corresponding to each PUSCH transmission opportunity, receive the PUSCH repeatedly sent by the terminal at each PUSCH transmission opportunity.

[0181] When determining the redundancy version corresponding to a certain PUSCH transmission opportunity, specifically, according to the position of the PUSCH transmission opportunity in the set, the redundancy version corresponding to the PUSCH transmission opportunity is determined from the redundancy version mode. Here, the redundancy version mode is indicated in the first DCI or the second DCI, and preferably, the redundancy version mode indicated by the first DCI and the second DCI in the embodiment of the present invention is the same.

[0182] In the embodiment of the present invention, it is assumed that the first DCI schedules N PUSCH transmission opportunities, and the second DCI schedules M PUSCH transmission opportunities; the redundancy version mode includes Z redundancy versions. The N may be configured by the first DCI, MACCE or RRC message; and the M may be configured by the second DCI, MAC CE or RRC message.

[0183] Preferably, in an embodiment of the present invention, the mapping mode of the PUSCH transmission timing includes a sequential mapping mode and a cyclic mapping mode; in the sequential mapping mode, the N PUSCH transmission timings scheduled by the first DCI are transmitted before or after the M PUSCH transmission timings scheduled by the second DCI; in the cyclic mapping mode, the PUSCH transmission timings scheduled by the first DCI and the PUSCH transmission timings scheduled by the second DCI are transmitted alternately in the time domain.

[0184] As a method for determining the redundancy version corresponding to the PUSCH transmission timing, specifically including:

[0185] For the i-th PUSCH transmission opportunity scheduled by the first DCI, a first remainder is obtained by performing a modulo Z operation on i; according to the first remainder, a redundant version corresponding to the PUSCH transmission opportunity is selected from the redundant version mode; for the j-th PUSCH transmission opportunity scheduled by the second DCI, a second remainder is obtained by performing a modulo Z operation on (N+j); according to the second remainder, a redundant version corresponding to the PUSCH transmission opportunity is selected from the redundant version mode; wherein the value range of i is 0 to N-1, and the value range of j is 0 to M-1.

[0186] As another determination method for the redundancy version corresponding to the PUSCH transmission occasion, it specifically includes:

[0187] When N = M: For the i-th PUSCH transmission occasion scheduled by the first DCI, perform a modulo-Z operation on 2i to obtain a third remainder; according to the third remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version pattern; for the j-th PUSCH transmission occasion scheduled by the second DCI, perform a modulo-Z operation on 2j + 1 to obtain a fourth remainder; according to the fourth remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version pattern;

[0188] When N > M: For the i-th PUSCH transmission occasion scheduled by the first DCI, perform a modulo-Z operation on 2i when i is less than or equal to M - 1, and perform a modulo-Z operation on i + M when i is greater than M - 1 to obtain a fifth remainder; according to the fifth remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version pattern; for the j-th PUSCH transmission occasion scheduled by the second DCI, perform a modulo-Z operation on 2j + 1 to obtain a sixth remainder; according to the sixth remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version pattern;

[0189] When N < M: For the i-th PUSCH transmission occasion scheduled by the first DCI, perform a modulo-Z operation on 2i to obtain a seventh remainder; according to the seventh remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version pattern; for the j-th PUSCH transmission occasion scheduled by the second DCI, perform a modulo-Z operation on 2j when j is less than or equal to N - 1, and perform a modulo-Z operation on j + N when j is greater than N - 1 to obtain an eighth remainder; according to the eighth remainder, select the redundancy version corresponding to this PUSCH transmission occasion from the redundancy version pattern;
