Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority from Chinese Patent Application No. 202011105261.1, filed in China on October 15, 2020, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of communications technology, and more particularly to a method, an apparatus, a device and a readable storage medium for repeatedly transmitting a configuration grant. [Background technology]

[0003] Communication systems support repeated transmission of configured grants to meet the high-reliability and low-latency requirements of Ultra-reliable and Low Latency Communication (URLLC) services. The relevant protocols restrict repeated transmissions to one set of configured grant settings. If the configured grant link for uplink repeated transmission is blocked, the reliability of data transmitted in this configured grant cannot be guaranteed. When a data transmission error in the configured grant is detected, the network sends downlink control information (DCI) to dynamically schedule data retransmission in the configured grant. While this mechanism can ensure data transmission reliability to a certain extent, it also introduces significant latency. Summary of the Invention [Problem to be solved by the invention]

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

[0032] FIG. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be referred to as a terminal device or user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and wearable devices include a wristband, earphones, glasses, etc. It should be noted that the embodiment of the present application is not limited to a specific type of the terminal 11.

It should be noted that in the embodiments of this application, only base stations in an NR system are used as examples, and the specific type of the base station is not limited.

[0033] In order to facilitate understanding of the embodiments of the present application, the following technical points will be first described below.

[0034] (1) Multi-Transmission Reception Point (TRP) Transmission

[0035] In a multi-TRP / multi-panel scenario, transmission reliability and throughput performance can be improved. In the downlink, a terminal can receive the same or different data from multiple TRPs. In the uplink, a terminal can transmit different data to multiple TRPs. Specifically, multiple control-resource sets (CORESETs) configured for a terminal by the network side are associated with different Radio Resource Control (RRC) parameter control resource set pool indices (CORESETPoolIndex), and correspond to different TRPs. Each TRP schedules its own uplink transmission Physical Uplink Shared Channel (PUSCH) by transmitting its own DCI. That is, in a multi-TRP scenario, PUSCH transmission is scheduled using multi-DCI.

[0036] (2) Setting up and activating the configured grant

[0037] Uplink configured grant transmission is a low-latency, low-overhead uplink transmission method. Configured grants are used in typical service scenarios such as Ultra-reliable and Low Latency Communication (URLLC). To further meet the lower latency and higher reliability requirements of URLLC services, the network side can simultaneously configure and activate multiple sets of Type 1 configured grants and / or Type 2 configured grants for a terminal.

[0038] A type 1 configured grant is enabled once configured by RRC, but a type 2 configured grant requires activation by a DCI. Up to 12 sets of configured grant configurations can be configured and activated in one bandwidth part (BWP), and each set of configurations is identified by an index (e.g., configuredGrantConfigIndex-r16 in the 16th edition of the protocol). If the network side configures multiple sets of configured grants, the value of the 4-bit "Hybrid Automatic Repeat Request Process Number (HARQ Process Number)" field in the DCI for activating a type 2 configured grant corresponds to the configured grant index and is used to indicate which set of type 2 configured grants the DCI will activate.

[0039] (3) Repeated transmission of configured grant

[0040] To further improve transmission reliability, the configured grant supports repetition of one transport block (TB). The number of repetitions and the corresponding redundancy version (RV) sequence are configured by RRC. For example, there are Type A and Type B repetitions. In Type A repetitions, multiple redundancy versions of one TB are transmitted in multiple consecutive slots. In Type B repetitions, the RRC configures the nominal transmission (including the nominal number of transmissions and the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied by each repetition). When a downlink symbol or slot boundary is encountered, one nominal transmission opportunity is split into multiple actual transmission opportunities.

[0041] However, in configured grant, repeated transmission is supported only for one set of configured grant, and only one set of spatial relationships is configured for one set of configured grant, so if the configured grant link for repeated transmission is blocked, the reliability of transmission cannot be guaranteed.

[0042] In addition, the "HARQ process number (HPN)" field value in the DCI for activating a type 2 configured grant is limited, and in the current activation method, the number of type 2 configured grants that can be configured in a terminal must not exceed the range of HPN values.

[0043] Hereinafter, with reference to the drawings, the method, device, equipment and readable storage medium for repeatedly transmitting a configuration grant provided in the embodiments of the present application will be described in detail through specific embodiments and application scenarios.

[0044] Referring to FIG. 2, an embodiment of the present application provides a method for repeatedly transmitting a configuration grant, where the method is performed by a terminal, and specifically includes the following steps 201 and 202:

[0045] In step 201, a first configuration grant configured by a network side is obtained, and at least two sets of first information are configured in the first configuration grant.

[0046] In step 202, the transmission block is repeatedly transmitted according to the at least two sets of first information.

[0047] That is, a transport block (TB) is repeatedly transmitted with the at least two sets of first information.

[0048] For example, the network side configures a plurality of type 1 and / or type 2 configuration grants for the terminal, each providing at least two sets of first information configurations, and when data arrives, the UE can select only one of the type 1 or activated type 2 configuration grants for repeated transmission.

[0049] In an embodiment of the present application, the at least two sets of first information include one or more of: (1) at least two sets of spatial relationships, (2) at least two sets of power control parameters, and (3) at least two sets of RV sequences, such as {0,2,3,1} or {0,3,0,3} or {0,0,0,0}.

[0050] In an embodiment of the present application, the first configuration grant is a type 1 configuration grant, and the spatial relationship of at least two sets of the first configuration grant is set by the network side through Radio Resource Control (RRC).

[0051] In an embodiment of the present application, the first configuration grant is a type 2 configuration grant, an HPN in a DCI for activating the first configuration grant corresponds to an index of the first configuration grant, and a sounding reference signal resource indicator (SRS resource indicator, SRI) field of the DCI indicates the at least two sets of spatial relationships.

[0052] Alternatively, the SRI field of the DCI may indicate two sets of spatial relationships as follows: Method 1-1 and Method 1-2.

[0053] In method 1-1, a first value of the SRI field of the DCI indicates a first set, and the first set includes the at least two sets of spatial relationships.

[0054] For example, a set including two sets of spatial relationships is configured by RRC, and one value of the SRI field of the DCI indicates one set including the two sets of spatial relationships, and the two sets of spatial relationships are indicated correspondingly.

[0055] In method 1-2, the SRI field of the DCI includes a first indication bit indicating a first set of spatial relationships among the at least two sets of spatial relationships, and a second indication bit indicating a second set of spatial relationships among the at least two sets of spatial relationships.

[0056] For example, one could expand the SRI field based on the existing one, say by extending SRI to 4 bits, with the first 2 bits indicating one set of spatial relationships and the last 2 bits indicating another set of spatial relationships.

[0057] In an embodiment of the present application, the first configuration grant is activated at least twice by a plurality of (eg, two) DCIs, and the SRI fields in the plurality of DCIs each indicate a set of spatial relationships.

[0058] For example, a Type 2 configuration grant is activated at least twice by two DCIs, where the DCIs for the two activations are from different Control Resource Sets (CORESET) and correspond to different CORESETPoolIndexes, and the SRI fields in the DCIs for the two activations indicate a set of spatial relationships, respectively.

[0059] In an embodiment of the present application, the first configuration grant is a type 1 configuration grant, and the power control parameters are:

[0060] (1-1) Open-loop power control parameters, such as p0-PUSCH-Alpha of P0 / Alpha,

[0061] (1-2) Path loss reference signal index (pathlossReferenceIndex),

[0062] (1-3) Closed loop power control parameters (powerControlLoopToUse).

[0063] In an embodiment of the present application, the first configuration grant is a type 2 configuration grant, and the power control parameters are:

[0064] (2-1) Open-loop power control parameters, such as p0-PUSCH-Alpha of P0 / Alpha,

[0065] (2-2) Closed loop power control parameter (powerControlLoopToUse).

[0066] Here, the SRI field in the DCI for activating the first configuration grant indicates at least two sets of path loss reference signal parameters.

[0067] In the embodiment of the present application, the methods for instructing power control parameters include the following Method 2-1 and Method 2-2.

[0068] In method 2-1, a second value of the SRI field of the DCI indicates a second set, and the second set includes two sets of path loss reference signal parameters.

[0069] For example, a parameter set including two sets of path loss reference signals is configured by RRC, and one value of the SRI in the DCI is mapped to one parameter set including the two sets of path loss reference signals.

[0070] In method 2-2, the SRI field of the DCI includes a third indicator bit indicating a first set of path loss reference signal parameters of the at least two sets of path loss reference signal parameters, and a fourth indicator bit indicating a second set of path loss reference signal parameters of the at least two sets of path loss reference signal parameters.

[0071] For example, the SRI field may be extended, e.g., to 4 bits, with the first 2 bits indicating that it is associated with one set of path loss reference signal parameters and the last 2 bits indicating that it is associated with another set of path loss reference signal parameters.

[0072] In an embodiment of the present application, the first configuration grant is a type 2 configuration grant, and a Transmit Power Control (TPC) field of the DCI (also referred to as single-DCI) for activating the first configuration grant indicates at least two sets of transmit power control commands.

[0073] The transmit power control field includes a fifth indicator bit indicating a transmit power control command corresponding to a first set of power control adjustment states and a sixth indicator bit indicating a transmit power control command corresponding to a second set of power control adjustment states.

[0074] For example, the TPC field may be expanded to 4 bits, with the first 2 bits representing TPC commands corresponding to a first set of power control adjustment states, and the last 2 bits representing TPC commands corresponding to a second set of power control adjustment states.

[0075] Optionally, the power control adjustment state is increased to four sets, and the power control parameters of each set maintain two power control adjustment states. In the two sets of power control parameter settings, the value of the closed-loop power control parameter (powerControlLoopToUse) of the first set of settings is "0" or "1", and the value of the closed-loop power control parameter (powerControlLoopToUse) of the second set of settings is "2" or "3".

[0076] The first two bits of the TPC in the extension field correspond to a first set of settings, and the last two bits correspond to a second set of settings.

[0077] In an 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.

[0078] In an embodiment of the present application, the mapping relationship between the at least two sets of power control parameters and the repeated transmission time of the first configuration grant is the same as the mapping relationship between the at least two sets of spatial relationships and the repeated transmission time of the first configuration grant, that is, if the spatial relationship mapping uses sequential mapping, the two sets of power control parameters must also use the same sequential mapping.

[0079] In an embodiment of the present application, the mapping relationship between the at least two sets of spatial relationships and the repetitive transmission time of the first configuration grant is:

[0080] (1) Sequential mapping and

[0081] (2) Cycle mapping and

[0082] (3) A relationship in which the repeated transmission time of a first portion of the first configuration grant corresponds to a first set of spatial relationships, and the repeated transmission time of the remaining second portion of the first configuration grant corresponds to a second set of spatial relationships.

[0083] For example, the first half of the repeated transmission time of the first configured grant uses a first set of spatial relationships, and the second half of the repeated transmission time uses a second set of spatial relationships.

[0084] It should be noted that for Type B repeat transmissions, the above spatial relationship mapping rules apply to nominal or actual repeat transmission opportunities.

[0085] In an embodiment of the present application, the RV value of the repeated transmission corresponding to the nth transmission opportunity of the K repetitions of the first configuration grant is the ((n-1) mod 4)+1th value of the RV sequence, where K and n are positive integers.

[0086] For example, if the RV sequence is set to {0,2,3,1} and the number of repetitions is 8, then for the nth transmission opportunity of the 8 repeated transmissions, when n=4, ((n-1) mod 4)+1=4, and the RV corresponding to the fourth transmission opportunity of the 8 repeated transmissions is the fourth value of the RV sequence {0,2,3,1}, i.e., "1".

[0087] In the embodiment of the present application, the reliability of data transmission in the set grant can be improved and the delay can be reduced.

[0088] Referring to FIG. 3, an embodiment of the present application provides a method for repeatedly transmitting a configuration grant, where the method is performed by a terminal, and specifically includes the following steps 301 and 302:

[0089] In step 301, at least two sets of configuration grants configured by a network side are obtained, and the HARQ process identifiers of the at least two sets of configuration grants are the same.

[0090] In step 302, the transmission block is repeatedly transmitted according to the at least two sets of configured grants.

[0091] That is, the transmission block is repeatedly transmitted according to the at least two sets of configured grants.

[0092] 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 configuredGrantTimer or other configurable time parameter.

[0093] For example, the network side configures and activates at least two sets of configured grants with the same HARQ process identifier for the UE. The at least two sets of configured grants are within a time window, which may be configuredGrantTimer or other configurable time parameters. When a TB starts to be transmitted in one set of configured grants, a time window timer is started, and within this timer, all configured grants with the same configured grant HARQ process identifier as the configured grant HARQ process identifier are allowed to repeat the transmission of the same TB. For the HARQ processes with the same HARQ process identifier, the New Data Indicators (NDIs) corresponding to the multiple sets of configured grants are not considered to be inverted.

[0094] In an embodiment of the present application, the at least two sets of configuration grants are associated with different TRPs.

[0095] In the embodiment of the present application, the association with different TRPs refers to association with different control resource set pool indices (CORESET Pool Index).

[0096] In an embodiment of the present application, the at least two sets of establishment grants include a type 1 establishment grant and a type 2 establishment grant.

[0097] The spatial relationship corresponding to the repeated transmission opportunity in the type 1 configuration grant is configured by the RRC, or the spatial relationship corresponding to the repeated transmission time in the type 2 configuration grant is indicated by the DCI that activates the type 2 configuration grant.

[0098] Further, optionally, the spatial relationship of each set of configured grants is respectively mapped to transmission opportunities in each set of configured grants.

[0099] In an embodiment of the present application, the at least two sets of configuration grants include a type 1 configuration grant and a type 2 configuration grant, and the power control parameters corresponding to the type 1 configuration grant are configured by the RRC, or the power control parameters corresponding to the type 2 configuration grant are indicated by a DCI that activates the type 2 configuration grant.

[0100] Furthermore, optionally, the power control parameters corresponding to each set of configured grants are respectively mapped to transmission opportunities in each set of configured grants.

[0101] In the embodiment of the present application, the closed-loop power control parameters of the configuration grants associated with different CORESETPoolIndex are independent of each other. That is, a TPC command of a DCI from a CORESET associated with the same CORESETPoolIndex can perform closed-loop power control only on the configuration grants associated with the same CORESETPoolIndex. Each CORESETPooLIndex maintains two power control adjustment states correspondingly, and the index value is 0 or 1.

[0102] In an embodiment of the present application, the sum of the repetition numbers of the at least two sets of configured grants is the total number of repeated transmissions.

[0103] In an embodiment of the present application, the RVs of the repeated transmissions of the at least two sets of configured grants are selected from the RV sequences configured in each configured grant, or are selected from the same RV sequence.

[0104] In an embodiment of the present application, at least two sets of configuration grants are configured with one 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.

[0105] In an embodiment of the present application, the at least two sets of configured grants are each configured with an RV sequence, and the RV value of the repeated transmission corresponding to the nth transmission opportunity in one configured grant is the ((n-1) mod 4)+1th value of the RV sequence.

[0106] In an embodiment of the present application, the at least two sets of configuration grants include type 2 configuration grants, and different DCIs for activating the type 2 configuration grants include the same HARQ process number, the HARQ process number corresponds to the same or different type 2 configuration grant index, and the different DCIs correspond to different CORESETPoolIndexes.

[0107] For example, a Type 2 configuration grant has the following activation methods:

[0108] DCIs from different CORESETs and corresponding to different CORESETPoolIndexes are each intended to activate a Type 2 configuration grant associated with the corresponding CORESETPoolIndex. The same value of the "HARQ process number" field of the different DCIs can respectively indicate the activation of Type 2 configuration grants with different indices. The Type 2 configuration grants with different indices are associated with different CORESETPoolIndex values.

[0109] Alternatively, a DCI for activating a Type 2 configuration grant from a CORESET associated with one CORESETPoolIndex may activate a Type 2 configuration grant associated with another CORESETPoolIndex. The same value of the "HARQ process number" field of the DCI corresponds to the same Type 2 configuration grant index.

[0110] In the embodiment of the present application, the reliability of data transmission in the set grant can be improved and the delay can be reduced.

[0111] Referring to FIG. 4, an embodiment of the present application provides a method for repeatedly transmitting a configuration grant, where the method is performed by a terminal, and specifically includes the following steps 401 and 402:

[0112] In step 401, the network side obtains DCI for scheduling a Physical Uplink Shared Channel (PUSCH).

[0113] In step 402, 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 within one time window, the transmission block scheduled by the DCI is repeatedly transmitted in the second configuration grant.

[0114] 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 PUSCH through DCI, if the HARQ process number indicated by the DCI within a time window is the same as the HARQ process in the configuration grant, it is considered that the TB scheduled by the DCI can be repeatedly transmitted in the configuration grant of the same HARQ process.

[0115] In an embodiment of the present application, the CORESETPoolIndex associated with the second configuration grant is the same as or different from the CORESETPoolIndex corresponding to the DCI.

[0116] Specifically, when a PUSCH transmission scheduled by DCI occurs, the HARQ process corresponding to the PUSCH starts the configuredGrantTimer, and while the configuredGrantTimer is running, other configured grants with the same HARQ process index as the HARQ process index of the PUSCH can also be used for repeated transmissions of the same TB scheduled by DCI.

[0117] The time window may be another timer with a configurable duration.

[0118] In the embodiment of the present application, the total number of repeated transmissions of the transport block is the sum of the number of repeated transmissions of the DCI scheduling and the number of repeated transmissions of the second configuration grant, that is, the total number of repetitions of one TB is the sum of the number of repeated transmissions of the DCI scheduling and the number of repeated transmissions of the second configuration grant.

[0119] In an embodiment of the present application, the PUSCH and the second configured grant are configured to have a spatial relationship, i.e., the PUSCH and the configured grant are dynamically scheduled to use the configured or indicated spatial relationship, respectively.

[0120] In an embodiment of the present application, the power control parameters used for transmission in the second configuration grant are the same as the power control parameters used for the DCI scheduling.

[0121] In the embodiment of the present application, the second configuration grant and the PUSCH have power control adjustment states independent of each other.

[0122] For example, the power control parameters used for transmission in the second configuration grant may be the same as those used in DCI scheduling. Alternatively, transmission in the second configuration grant may use self-configured or instructed power control parameters. The power control adjustment states of the second configuration grant and the dynamically scheduled PUSCH are independent of each other. The same power control adjustment state index corresponds to different power control adjustment state processes.

[0123] In an embodiment of the present application, the RV used for transmission in the second configuration grant is selected from the RV sequence indicated by the DCI scheduling.

[0124] For example, the redundancy version used for transmission in the second configuration grant may use the same RV sequence as indicated by the DCI scheduling, and one redundancy version is selected from the RV sequence according to the global count.

[0125] Optionally, transmissions in the second configuration grant use a self-configured RV sequence, and a redundancy version corresponding to each transmission opportunity is obtained by counting transmission opportunities in the second configuration grant. The redundancy version of the repeat transmission corresponding to the nth transmission opportunity takes the ((n-1) mod 4)+1th value of the RV sequence, where n counts only the repeat opportunities in the second configuration grant.

[0126] In the embodiment of the present application, the reliability of data transmission in the set grant can be improved and the delay can be reduced.

[0127] Hereinafter, embodiments of the present application will be described with reference to Examples 1 to 7. [Example]

[0128] One set of Type 1 Configured Grant (abbreviated as Type 1CG) configures at least two sets of spatial relationship or power control parameters, and a DCI for activating a Type 2 Configured Grant (abbreviated as Type 2CG) indicates at least two sets of spatial relationship or power control parameters. Repetitions of one TB are mapped to different spatial relationship indication information (spatial transmit beams) and transmitted at different transmit powers.

[0129] As shown in Figure 5, the number of repeated transmissions is four. The mapping between repeated transmission opportunities and spatial relationships or power control parameters may be sequential, i.e., the first and second transmissions use a first set of spatial relationships or power control parameters, and the third and fourth transmissions use a second set of spatial relationships or power control parameters. The mapping may be cyclic, i.e., the first and third transmission opportunities use a first set of spatial relationships or power control parameters, and the second and fourth transmissions use a second set of spatial relationships or power control parameters. The spatial relationships are bound to each transmission opportunity, and when data arrives, it is transmitted using the spatial relationships or power control parameters corresponding to that opportunity based on which transmission opportunity it is to transmit. [Example]

[0130] In relation to embodiment 1 of the invention, for a Type 2 Configured Grant, multiple DCIs from different CORESETs and corresponding to different CORESETPoolIndexes can be used simultaneously to activate the same set of Type 2 Configured Grant settings.

[0131] For example, in a DCI format for activating a Type 2 Configured Grant from a CORESET associated with CORESETPoolIndex=0, "HARQ process number"=1, i.e., the DCI activates a Type 2 Configured Grant with an index of 1. When the UE receives the DCI for activation, it stores information about the Configured Grant. At this time, if "HARQ process number"=1 in the DCI format for activating a Type 2 Configured Grant from a CORESET associated with CORESETPoolIndex=1 received by the UE, the UE stores information such as the SRI, Transmitted Precoding Matrix Indicator (TPMI), and TPC in the DCI. As a result, the UE obtains two sets of transmission information including two sets of spatial relationships or power control parameters. [Example]

[0132] The network configures and activates at least two sets of Type 1 and / or Type 2 Configured Grants for the UE, each set of Configured Grants being associated with a CORESETPoolIndex, the two sets of Configured Grants have the same period, no HARQ process ID offset is configured for either or the offset value is 0, and the time difference between the first transmission opportunities of the two sets of Configured Grants is less than one period, and the HARQ processes of the two sets of Configured Grants are completely overlapped according to the Configured Grant HARQ process index determination rule.

[0133] Repeated transmissions by a UE are possible using two sets of Configured Grants, e.g., Configured grant 1 and Configured grant 2, which have the same HARQ process. As shown in Figure 6, Configured Grant 1 is associated with CORESETPoolIndex=0 and has one set of spatial relationship or power control parameters configured, while CORESETPoolIndex=1 is associated with TRP2 and has another set of spatial relationship or power control parameters configured. One TB of a UE can be repeatedly transmitted in a total of eight repeated transmission opportunities of the two sets of Configured Grants shown in the figure. The transmit spatial beam information and power control parameters for each repeated transmission opportunity are determined by the settings of the two sets of Configured Grants, respectively. [Example]

[0134] Multiple Type 2 Configured Grants associated with a CORESETPoolIndex are activated by a DCI for activating a Type 2 Configured Grant from a CORESET associated with the corresponding CORESETPoolIndex, and the same value of the "HARQ process number" field of the DCI corresponds to different Type 2 Configured Grant indices in different TRPs, and the correspondence is shown in Table 1.

[0135] [Table 1] [Example]

[0136] In relation to Example 3, for a DCI for activating a Type 2 Configured Grant, we focus only on the "HARQ process number" field, regardless of which CORESET under which CORESETPoolIndex it comes from. In this case, a DCI from one TRP can activate a Type 2 Configured Grant associated with another TRP. The activation correspondence between the "HARQ process number" field of a DCI and the Type 2 Configured Grant index is shown in Tables 2 and 3.

[0137] In Table 2, all Type 2 Configured Grant settings are uniformly assigned index values, and the value of the "HARQ process number" field of the DCI for activating a Type 2 Configured Grant corresponds to the activated Type 2 Configured Grant index. This DCI may be from a CORESET corresponding to any CORESETPoolIndex.

[0138] [Table 2]

[0139] In Table 3, the most significant bit of the “HARQ process number” field for activating a Type 2 Configured Grant is for indicating which CORESETPoolIndex the DCI is to activate the Type 2 Configured Grant associated with, and the value of the lower 3 bits represents the Type 2 Configured Grant index under the corresponding activated CORESETPoolIndex.

[0140] [Table 3] [Example]

[0141] In relation to Example 3, the two sets of Configured Grants for transmission repetition are as follows:

[0142] 1) The RV sequence is set by each Configured Grant in each set, and the redundant version of the repeat transmission corresponding to the nth transmission opportunity takes the ((n-1) mod 4)+1th value of the RV sequence. n only counts transmission opportunities for the Configured Grant in the same set.

[0143] 2) The RV sequence for repeated transmissions uses the RV sequence configured in the Configured Grant associated with CORESETPoolIndex=0. 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, where n is the number of transmission opportunities for the two Configured Grants. [Example]

[0144] The network side 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 DCI is the same as the Configured Grant, the configuredGrantTimer runs, and the TB scheduled by DCI can be repeatedly transmitted in the Configured Grant. The CORESETPoolIndex associated with the DCI is different from the Configured Grant.

[0145] As shown in Figure 7, the DCI from CORESET associated with CORESETPoolIndex=0 dynamically schedules repeated transmission of PUSCH, with the number of transmissions being 4. The HARQ process identifier of the Configured Grant associated with CORESETPoolIndex=1 is the same as the HARQ process indicated in the DCI, and the TB scheduled by the DCI may be continuously and repeatedly transmitted in the Configured Grant. It is assumed that the NDI corresponding to the Configured Grant does not invert. The transmit spatial beam information or power control parameters for the first to fourth repeated transmissions are indicated by the DCI, and the fifth to eighth repeated transmissions are configured by RRC or indicated by the DCI for activating the Type 2 Configured Grant.
