Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a method, device, equipment and readable storage medium for repeated transmission of configuration authorization. Background Art

[0002] The communication system supports repeated transmission of configured grant to meet the high reliability and low latency requirements of Ultra-relaible and Low Latency Communication (URLLC) services. Relevant protocols restrict repeated transmission to be performed on a set of configured grant configurations. If the configured grant link used for uplink repeated transmission is blocked, the reliability of the data transmitted on the configured grant cannot be guaranteed. When the network side detects a configured grant transmission data error, it sends downlink control information (Downlink Control Information, DCI) to dynamically schedule data retransmission on the configured grant. This mechanism can ensure the reliability of data transmission to a certain extent, but it also brings a large delay. Summary of the invention

However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0041] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 can be a base station or a core network, wherein the base station can be referred to as 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, a transmitting and receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to the specified technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0042] In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced below:

[0043] (1) About multiple transmission and reception points (TRP) transmission:

[0044] The multi-transmitting and receiving point / multi-antenna panel (multi-TRP / multi-panel) scenario can increase the reliability and throughput performance of transmission. In the downlink, the terminal can receive the same or different data from multiple TRPs. In the uplink, the terminal can send different data to multiple TRPs. Specifically, the multiple control resource sets (control-resource set, CORESET) configured by the network side for the terminal are associated with different radio resource control (Radio Resource Control, RRC) parameters control resource set pool index (CORESETPoolIndex), corresponding to different TRPs respectively. Each TRP schedules its own uplink transmission physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) by sending its own DCI, that is, in the Multi-TRP scenario, multiple DCI (Multi-DCI) is used to schedule PUSCH transmission.

[0045] (2) About configuration and activation of configured grant:

[0046] Uplink configured grant transmission is a low-latency, low-overhead uplink transmission solution. Configured grant is used in typical business scenarios such as Ultra-relaible and Low Latency Communication (URLLC). In order to further meet the requirements of URLLC services for lower latency and higher reliability, the network side can simultaneously configure and activate multiple sets of type 1 configured grant and / or type 2 configured grant for the terminal.

[0047] For type 1 configured grant, it takes effect after RRC configuration, while type 2 configured grant needs to be activated by DCI to take effect. Up to 12 sets of configured grant configurations can be configured and activated on a bandwidth part (Bandwidth Part, BWP), and each set of configurations is identified by an index (such as configuredGrantConfigIndex-r16). When multiple sets of configured grants are configured on the network side, the value of the 4-bit "Hybrid Automatic Repeat Request Process Number (HARQ process number, HPN)" field in the DCI used for type 2 configured grant activation corresponds to the configured grant index, which is used to indicate which set of type 2 configured grant is specifically activated by the DCI.

[0048] (3)Configured grant repeated transmission

[0049] In order to further improve the reliability of transmission, the configured grant supports the repeated transmission (Repetition) of a transport block (TransportBlock, TB). The number of repeated transmissions and the redundant version (Redundancy version, RV) sequence corresponding to the repeated transmission are configured by RRC. For example, type A and type B repeated transmissions. In the type A repeated transmission scheme, multiple redundant versions of a TB are transmitted on multiple consecutive time slots. In the type B repeated transmission scheme, RRC configures the nominal transmission (including the nominal number of transmissions and the number of orthogonal frequency division multiplex (OFDM) symbols occupied by each repetition). When encountering a downlink symbol or time slot boundary, a nominal transmission opportunity will be divided into multiple actual transmission opportunities.

[0050] However, since the configured grant only supports repeated transmission on a set of configured grants, and a set of configured grants only configures one set of spatial relationships, when the configured grant link used for repeated transmission is blocked, the transmission reliability cannot be guaranteed.

[0051] In addition, the value of the "HARQ process number (HPN)" field in the DCI used to activate the type 2 configured grant is limited. Under the current activation method, the number of type 2 configured grants that can be configured by the terminal cannot exceed the value range of HPN.

[0052] In conjunction with the accompanying drawings, a method, apparatus, device and readable storage medium for repeated transmission of configuration authorization provided in an embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0053] See also Figure 2 The embodiment of the present application provides a method for configuring authorized repeated transmission. The execution subject of the method is a terminal, and the specific steps include: step 201 and step 202.

[0054] Step 201: Obtain a first configuration authorization configured on the network side, wherein the first configuration authorization configures at least two sets of first information;

[0055] Step 202: Repeatedly transmit the transmission block according to the at least two sets of first information.

[0056] That is, the transport block (Transport Block, TB) is repeatedly transmitted through the at least two sets of first information.

[0057] For example, the network side configures multiple type 1 and / or type 2 configuration authorizations that provide at least two sets of first information configurations for the terminal. When data arrives, the UE can only select one type 1 or activated type 2 configuration authorization for repeated transmission.

[0058] In an embodiment of the present application, the at least two sets of first information include one or more of the following: (1) at least two sets of spatial relationships; (2) at least two sets of power control parameters; at least two sets of RV sequences, for example, the RV sequence is {0, 2, 3, 1} or {0, 3, 0, 3} or {0, 0, 0, 0}.

[0059] In an embodiment of the present application, the first configuration authorization is a type 1 configuration authorization, and at least two sets of spatial relationships of the first configuration authorization are configured by the network side through radio resource control (Radio Resource Control, RRC).

[0060] In an embodiment of the present application, the first configuration authorization is a type 2 configuration authorization, which is used to activate the HPN in the DCI of the first configuration authorization corresponding to the index of the first configuration authorization, and the channel sounding reference signal resource indication (SRS resource indicator, SRI) field of the DCI indicates the at least two sets of spatial relationships.

[0061] Optionally, there are two methods for the SRI field of the DCI to indicate two sets of spatial relationships:

[0062] Method 1-1: A first value of the SRI field of the DCI indicates a first set, where the first set includes the at least two sets of spatial relationships;

[0063] For example, a set including two sets of spatial relationships is configured through RRC, and a value of the SRI field of the DCI indicates a set including two sets of spatial relationships, correspondingly indicating two sets of spatial relationships.

[0064] Method 1-2: The SRI field of the DCI includes: a first indicator bit and a second indicator bit, the first indicator bit indicates a first set of spatial relationships among at least two sets of spatial relationships, and the second indicator bit indicates a second set of spatial relationships among at least two sets of spatial relationships.

[0065] For example, the SRI is expanded on the existing basis, for example, the SRI is expanded to 4 bits, the first two bits indicate one set of spatial relationships, and the last two bits indicate another set of spatial relationships.

[0066] In an embodiment of the present application, the first configuration authorization is activated at least twice by multiple DCIs (for example, two), and the SRI fields in the multiple DCIs respectively indicate a set of spatial relationships.

[0067] For example, the type 2 configuration authorization is activated at least twice by two DCIs. The two activation DCIs are from different control resource sets (Control Resource Sets, CORESETs) and correspond to different CORESETPoolIndex. The SRI fields in the two DCIs used for activation respectively indicate a set of spatial relationships.

[0068] In this embodiment of the present application, the first configuration authorization is a type 1 configuration authorization, and the power control parameter includes one or more of the following:

[0069] (1-1) Open-loop power control parameters;

[0070] For example, p0-PUSCH-Alpha of P0 / Alpha;

[0071] (1-2) path loss reference signal index, for example, pathlossReferenceIndex;

[0072] (1-3) Closed-loop power control parameters, such as powerControlLoopToUse.

[0073] In this embodiment of the present application, the first configuration authorization is a type 2 configuration authorization, and the power control parameter includes one or more of the following:

[0074] (2-1) Open-loop power control parameters;

[0075] For example, p0-PUSCH-Alpha of P0 / Alpha;

[0076] (2-2) Closed-loop power control parameters;

[0077] For example, powerControlLoopToUse.

[0078] The SRI field in the DCI used to activate the first configuration authorization indicates at least two sets of path loss reference signal parameters.

[0079] In an embodiment of the present application, the method for indicating a power control parameter includes:

[0080] Method 2-1: The second value of the SRI field of the DCI indicates a second set, where the second set includes two sets of path loss reference signal parameters;

[0081] For example, the RRC configuration includes two sets of path loss reference signal parameter sets, and a value of SRI in the DCI is mapped to a set of two path loss reference signal parameter sets.

[0082] Method 2-2: The SRI field of the DCI includes: a third indicator bit and a fourth indicator bit, the third indicator bit indicates a first set of path loss reference signal parameters among at least two sets of path loss reference signal parameters, and the fourth indicator bit indicates a second set of path loss reference signal parameters among at least two sets of path loss reference signal parameters.

[0083] For example, the SRI field is extended, for example, the SRI field is extended to 4 bits, the first two bits indicate the association with one set of path loss reference signals, and the last two bits indicate the association with another set of path loss reference signals.

[0084] In the embodiment of the present application, the first configuration authorization is a type 2 configuration authorization, which is used to activate the transmit power control (TPC) field of the DCI (or referred to as a single DCI (single-DCI)) of the first configuration authorization to indicate at least two sets of transmit power control commands;

[0085] The transmit power control field includes: a fifth indicator bit and a sixth indicator bit, the fifth indicator bit indicates a transmit power control command corresponding to a first set of power control adjustment states, and the sixth indicator bit indicates a transmit power control command corresponding to a second set of power control adjustment states.

[0086] For example, the TPC field is expanded to 4 bits, the first two bits represent the TPC corresponding to the first set of power control adjustment states, and the last two bits represent the TPC corresponding to the second set of power control adjustment states.

[0087] Optionally, the power control adjustment states are increased to 4 sets, and each set of power control parameters maintains two power control adjustment states. For the above two sets of power control parameter configurations, the value of the closed-loop power control parameter (powerControlLoopToUse) of the first set of configurations is "0" or "1", and the value of the closed-loop power control parameter (powerControlLoopToUse) of the second set of configurations is "2" or "3".

[0088] The first two bits of the TPC in the extended domain correspond to the first set of configurations, and the last two bits correspond to the second set of configurations.

[0089] In the embodiment of the present application, the at least two sets of power control parameters correspond one-to-one to the at least two sets of spatial relationships.

[0090] In the embodiment of the present application, the mapping relationship between the at least two sets of power control parameters and the first configuration authorization repetition transmission time is the same as the mapping relationship between the at least two sets of spatial relationships and the first configuration authorization repetition transmission time. That is, when the spatial relationship mapping adopts sequential mapping, the two sets of power control parameters must also adopt the same sequential mapping.

[0091] In an embodiment of the present application, the mapping relationship between the at least two sets of spatial relationships and the first configuration authorization repetitive transmission time includes any one of the following:

[0092] (1) Sequential mapping;

[0093] (2) Circular mapping;

[0094] (3) The first part of the repeated transmission time authorized by the first configuration corresponds to the first set of spatial relationships, and the remaining second part of the repeated transmission time authorized by the first configuration corresponds to the second set of spatial relationships.

[0095] For example, the first half of the repetition transmission time of the first configuration authorization adopts the first spatial relationship, and the remaining half of the repetition transmission time adopts the second set of spatial relationships.

[0096] It should be noted that, for repeated transmission of type B, the above-mentioned mapping rule of the spatial relationship is applied to the nominal or actual repeated transmission timing.

[0097] In an embodiment of the present application, the RV value of the repeated transmission corresponding to the nth transmission opportunity of K repetitions authorized by the first configuration is the ((n-1) mod 4) + 1th value of the RV sequence, where K and n are positive integers.

[0098] For example, when the RV sequence is configured as {0, 2, 3, 1} and the number of repetitions is 8, the nth transmission opportunity of 8 repeated transmissions (when n=4) is: ((n-1) mod 4) + 1 = 4; then the RV corresponding to the 4th transmission opportunity of 8 repeated transmissions takes the fourth value in the RV sequence {0, 2, 3, 1}, that is, "1".

[0099] In the embodiments of the present application, the reliability of data transmission on the configuration authorization can be improved while reducing the latency.

[0100] See also Figure 3 An embodiment of the present application provides a method for configuring authorized repeated transmission. The execution subject of the method is a terminal, and the specific steps include: step 301 and step 302.

[0101] Step 301: Acquire at least two sets of configuration authorizations configured by the network side, where the HARQ process identifiers of the at least two sets of configuration authorizations are the same;

[0102] Step 302: Repeat transmission of the transmission block according to the at least two sets of configuration authorizations.

[0103] That is, the transmission block is repeatedly transmitted through the at least two sets of configuration grants.

[0104] In an embodiment of the present application, the at least two sets of configured grants are repeatedly transmitted within a time window, and the time window is a configured grant timer (configuredGrantTimer), or other configurable time parameters.

[0105] For example, the network side configures and activates at least two sets of configuration grants with the same HARQ process identifier for the UE. At least two sets of configuration grants are within a time window, which can be a configuredGrantTimer, or other configurable time parameters. When a TB starts to be transmitted on a set of configured grants, the time window timer is started. Within this timer, all configured grants with the same HARQ process identifier as the configured grant are allowed to transmit a TB repeatedly. For the HARQ process with the HARQ process identifier, the new data indication (New Data Indicator, NDI) corresponding to multiple sets of configured grants is considered not to flip.

[0106] In an embodiment of the present application, the at least two sets of configuration authorizations are respectively associated with different TRPs.

[0107] In the embodiment of the present application, the associating different TRPs refers to associating with different control resource set pool indexes (CORESETPool Index).

[0108] In the embodiment of the present application, the at least two sets of configuration authorizations include: type 1 configuration authorization and type 2 configuration authorization;

[0109] Among them, the spatial relationship corresponding to the repeated transmission opportunity on the type 1 configuration authorization is configured by RRC, or the spatial relationship corresponding to the repeated transmission time on the type 2 configuration authorization is indicated by the DCI that activates the type 2 configuration authorization.

[0110] Further, optionally, the spatial relationship of each set of configuration authorizations is respectively mapped to the transmission opportunities on each set of configuration authorizations.

[0111] In an embodiment of the present application, the at least two sets of configuration authorizations include: type 1 configuration authorization and type 2 configuration authorization, the power control parameters corresponding to the type 1 configuration authorization are configured by RRC, or the power control parameters corresponding to the type 2 configuration authorization are indicated by the DCI that activates the type 2 configuration authorization.

[0112] Further, optionally, the power control parameters corresponding to each set of configuration grants are respectively mapped to the transmission opportunities on each set of configuration grants.

[0113] In the embodiment of the present application, the closed-loop power control parameters of the configuration authorizations associated with different CORESETPoolIndex are independent of each other. That is, the TPC command of the DCI from the CORESET associated with the same CORESETPoolIndex can only perform closed-loop power control on the configuration authorization associated with the same CORESETPoolIndex. Each CORESETPoolIndex maintains two power control adjustment states, with index values ​​of 0 or 1.

[0114] In the embodiment of the present application, the sum of the number of repetitions of the at least two sets of configuration authorizations is the total number of repeated transmissions.

[0115] In an embodiment of the present application, the at least two sets of RVs for repeated transmission of the configuration authorization are selected from the RV sequence configured by each configuration authorization, or are selected from the same RV sequence.

[0116] In an embodiment of the present application, at least two sets of configuration authorizations configure an RV sequence, and the RV value of the repeated transmission corresponding to the nth transmission opportunity is the ((n-1) mod 4)+1th value of the RV sequence.

[0117] In an embodiment of the present application, the at least two sets of configuration authorizations respectively configure RV sequences, wherein the RV value of the repeated transmission corresponding to the nth transmission opportunity on a configuration authorization is the ((n-1) mod 4) + 1th value of the RV sequence.

[0118] In an embodiment of the present application, the at least two sets of configuration authorizations include type 2 configuration authorizations, and different DCIs used to activate the type 2 configuration authorizations include the same HARQ process number, and the HARQ process number corresponds to the same or different type 2 configuration authorization indexes, and the different DCIs correspond to different CORESETPoolIndex.

[0119] For example, type 2 configuration authorization has the following activation methods:

[0120] DCIs from different CORESETs and corresponding to different CORESETPoolIndex are used to activate type 2 configuration grants associated with the corresponding CORESETPoolIndex. The same value of the "HARQ process number" field of the different DCIs allows the activation of type 2 configuration grants with different indexes. The type 2 configuration grants with different indexes are associated with different CORESETPoolIndex values.

[0121] Optionally, a DCI for activation of a type 2 configuration grant from a CORESET associated with a CORESETPoolIndex allows activation of a type 2 configuration grant associated with another CORESETPoolIndex. The same value of the "HARQ processnumber" field of the DCI corresponds to the same type 2 configuration grant index.

[0122] In the embodiments of the present application, the reliability of data transmission on the configuration authorization can be improved while reducing the latency.

[0123] See also Figure 4 The embodiment of the present application provides a method for configuring authorized repeated transmission. The execution subject of the method is a terminal, and the specific steps include: step 401 and step 402.

[0124] Step 401: Obtain the DCI of the Physical Uplink Shared Channel (PUSCH) scheduled by the network side;

[0125] Step 402: within a time window, if the HARQ process number (or configuration grant) indicated by the DCI is the same as the HARQ process number of the second configuration grant, the transmission block scheduled by the DCI is repeatedly transmitted on the second configuration grant.

[0126] For example, the network side configures at least one type 1 and / or type 2 configuration grant associated with CORESETPoolIndex for the terminal. When the network side dynamically schedules a PUSCH through DCI, within a time window, if the HARQ process number indicated by the DCI is the same as the HARQ process of the configuration grant, it is considered that the TB scheduled by the DCI is allowed to be repeatedly transmitted on the configuration grant of the same HARQ process.

[0127] In an embodiment of the present application, the CORESETPoolIndex associated with the second configuration authorization is the same as or different from the CORESETPoolIndex corresponding to the DCI.

[0128] Specifically, when a DCI-scheduled PUSCH transmission occurs, the HARQ process corresponding to the PUSCH starts the configuredGrantTimer. During the running period of the configuredGrantTimer, other configured grants with the same HARQ process index as the PUSCH can also be used to transmit the repetition of the same TB scheduled by the DCI.

[0129] The time window may be other timers of configurable duration.

[0130] In the embodiment of the present application, the total number of repetitions of the transmission block is the sum of the number of repetitions scheduled by the DCI and the number of repetitions authorized by the second configuration. That is, the total number of repetitions of a TB is the total number of repetitions scheduled by the DCI and the number of repetitions authorized by the second configuration.

[0131] In the embodiment of the present application, the PUSCH and the second configured grant are configured with a spatial relationship respectively, that is, the dynamic scheduling of the PUSCH and the configured grant respectively adopts the spatial relationship configured or indicated by each.

[0132] In an embodiment of the present application, the power control parameter used for transmission on the second configuration grant is the same as the power control parameter used for the DCI scheduling.

[0133] In this embodiment of the present application, the second configuration authorization is independent of the power control adjustment state of the PUSCH.

[0134] For example, the power control parameters used for transmission on the second configuration grant may be the same as those used for DCI scheduling. Optionally, the transmission on the second configuration grant uses the power control parameters configured or indicated by itself. The power control adjustment states of the second configuration grant and the dynamically scheduled PUSCH are independent of each other. Even if the same power control adjustment state index is used, different power control adjustment state processes are corresponding.

[0135] In this embodiment of the present application, the RV used for transmission on the second configuration grant is selected from the RV sequence indicated by the DCI scheduling.

[0136] For example, the redundancy version used for transmission on the second configuration grant may use the same RV sequence as the DCI scheduling indication, and a redundancy version is selected in the RV sequence in a global counting manner.

[0137] Optionally, the transmission on the second configuration authorization uses a self-configured RV sequence, and the corresponding redundant version on each transmission opportunity is obtained by counting the transmission opportunities on the second configuration authorization. The redundant version of the repeated transmission corresponding to the nth transmission opportunity takes the ((n-1) mod 4) + 1th value of the RV sequence, and n only counts the repetition opportunities of the second configuration authorization.

[0138] In the embodiments of the present application, the reliability of data transmission on the configuration authorization can be improved while reducing the latency.

[0139] The implementation methods of the present application are described below in conjunction with Examples 1 to 7.

[0140] Embodiment 1

[0141] A set of type 1 Configured Grant (referred to as type 1CG) configures at least two sets of spatial relationships or power control parameters, and the DCI activated by type 2 Configured Grant (referred to as type 2CG) indicates at least two sets of spatial relationships or power control parameters. A TB is repeatedly mapped to different spatial relationship indication information (spatial transmit beams) and transmitted using different transmit powers.

[0142] like Figure 5 As shown, the number of repeated transmissions is 4. The mapping between repeated transmission opportunities and spatial relationships or power control parameters can be sequentially mapped, that is, the first and second transmissions are sent using the first set of spatial relationships or power control parameters, and the third and fourth transmissions are sent using the second set of spatial relationships or power control parameters. It can also be cyclically mapped, that is, the first and third transmission opportunities use the first set of spatial relationships or power control parameters, and the second and fourth transmissions use the second set of spatial relationships or power control parameters. The spatial relationship is bound to each transmission opportunity. When data arrives, it is transmitted on which transmission opportunity and is sent using the spatial relationship or power control parameters corresponding to that opportunity.

[0143] Embodiment 2

[0144] In association with the first embodiment of the invention, for Type 2 Configured Grant, multiple DCIs from different CORESETs corresponding to different CORESETPoolIndex can be used to activate the same set of Type 2 Configured Grant configurations at the same time.

[0145] For example, in the DCI format for type 2 Configured Grant activation from the CORESET with CORESETPoolIndex=0, "HARQ process number"=1, that is, the DCI activates type 2 Configured Grant with index 1. When the UE receives the activation DCI, it saves the information of the Configured Grant. At this time, when the UE receives the DCI format for type 2 Configured Grant activation from the CORESET associated with CORESETPoolIndex=1, the terminal saves the SRI, Transmitted Precoding Matrix Indicator (TPMI), TPC and other information in the DCI. At this point, the terminal obtains two sets of transmission information including two sets of spatial relationships or power control parameters.

[0146] Embodiment 3

[0147] The network side configures and activates at least two sets of type 1 and / or type 2 Configured Grant for the UE, and each set of Configured Grant is associated with a CORESETPoolIndex. The two sets of Configured Grant have the same period, and the offset of the HARQ process ID is not configured, or the offset value is 0, and the time difference between the first transmission timings of the two sets of Configured Grant t is less than one period. At this time, according to the Configured Grant HARQ process index determination rule, the HARQ processes of the two sets of Configured Grant completely overlap.

[0148] The UE is allowed to perform repeated transmissions on the two sets of Configured Grants with the same HARQ process, such as Configured grant 1 and Configured grant 2. Figure 6As shown, Configured Grant1 is associated with CORESETPoolIndex=0, and a set of spatial relationships or power control parameters are configured. CORESETPoolIndex=1 is associated with TRP2, and another set of spatial relationships or power control parameters are configured. A TB of a UE can be repeatedly transmitted on a total of 8 repetitive transmission opportunities in the two sets of ConfiguredGrant in the figure. The transmission spatial beam information and power control parameters of each repetitive transmission opportunity are determined by the configuration of the two sets of Configured Grants.

[0149] Embodiment 4

[0150] Multiple type 2 configured associated with CORESETPoolIndex are activated by the DCI for type 2 configured grant activation from the CORESET associated with the corresponding CORESETPoolIndex. The same value of the "HARQ process number" field of the DCI corresponds to different type 2 configured grant indexes under different TRPs. The corresponding relationship is shown in Table 1:

[0151] Table 1:

[0152]

[0153] Embodiment 5

[0154] In association with Embodiment 3, the DCI used for activation of Type 2 Configured Grant does not consider which CORESET under CORESETPoolIndex it comes from, and only focuses on the "HARQ process number" field. This allows DCI from one TRP to activate the Type 2 Configured Grant associated with another TRP. The corresponding relationship between the "HARQ processnumber" field of the DCI and the activation of the Type 2 Configured Grant index is shown in Table 2 and Table 3:

[0155] Table 2, all type 2 Configured Grant configurations are uniformly assigned index values, and the value of the "HARQ process number" field of the DCI used to activate the type 2 Configured Grant corresponds to the activated type 2 Configured Grant index. This DCI can be from any CORESET corresponding to CORESETPoolIndex.

[0156] Table 2:

[0157] HARQ process number Type 2 Configured Grant Index 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11 11 reserve

[0158] Table 3, the highest bit of the "HARQ process number" field used to activate the Type 2 Configured Grant is used to indicate which CORESETPoolIndex the DCI is to activate the Type 2 Configured Grant associated with, and the values ​​of the lower 3 bits represent the Type 2 Configured Grant index under the corresponding CORESETPoolIndex to be activated.

[0159] Table 3:

[0160]

[0161]

[0162] Embodiment 6

[0163] Associated with the third embodiment, two sets of repeated Configured Grants are used to transmit:

[0164] 1) The RV sequence is configured by each set of Configured Grant. The redundant version of the repeated transmission corresponding to the nth transmission opportunity takes the ((n-1) mod 4) + 1th value of the RV sequence. n only counts the transmission opportunities of the same set of Configured Grant.

[0165] 2) The RV sequence used for repeated transmission uses the RV sequence configured in the Configured Grant associated with CORESETPoolIndex = 0. The redundant version of repeated transmission corresponding to the nth transmission opportunity takes the ((n-1) mod 4) + 1th value of the RV sequence. n counts the number of transmission opportunities of two Configured Grants.

[0166] Embodiment 7

[0167] The network configures and activates at least one set of Configured Grant associated with CORESETPoolIndex for the UE. When the network dynamically schedules PUSCH, the HARQ process index indicated by the DCI is the same as the Configured Grant, and the configuredGrantTimer is running, allowing the repeated transmission of the TB scheduled by the DCI on the Configured Grant. The CORESETPoolIndex associated with the DCI is different from the Configured Grant.

The HARQ process identifier of the Configured Grant associated with CORESETPoolIndex=1 is the same as the HARQ process indicated in the DCI, allowing the TB scheduled by the DCI to continue to be repeatedly transmitted on the Configured Grant. And it is assumed that the NDI corresponding to the Configured Grant is not flipped.
