Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular to a channel transmission method and device, and a storage medium. Background Art

[0002] In order to improve the coverage at the cell edge and provide a more balanced service quality within the service cell, multi-point coordination is still an important technical means in the NR (New Radio) system.

[0003] From the perspective of network morphology, network deployment with a large number of distributed access points combined with centralized baseband processing will be more conducive to providing a balanced user experience rate and significantly reduce the delay and signaling overhead caused by handover. With the increase of frequency bands, relatively dense access point deployment is also required from the perspective of ensuring network coverage. In high frequency bands, with the improvement of the integration of active antenna equipment, modular active antenna arrays will be more inclined to be adopted. The antenna array of each TRP (Transmission and Receiving Points) can be divided into several relatively independent antenna panels, so the shape and number of ports of the entire array can be flexibly adjusted according to the deployment scenario and business needs. Antenna panels or TRPs can also be connected by optical fiber for more flexible distributed deployment. In the millimeter wave band, as the wavelength decreases, the blocking effect caused by obstacles such as human bodies or vehicles will be more significant. In this case, from the perspective of ensuring the robustness of link connections, it is also possible to use the collaboration between multiple TRPs or PANELs to transmit / receive from multiple beams at multiple angles, thereby reducing the adverse effects of the blocking effect.

[0004] In the R16 research phase, based on the application of multi-point coordinated transmission technology between downlink multiple TRPs or PANELs, the transmission of PDSCH (Physical Downlink Shared Channel) was enhanced. Since data transmission includes scheduling feedback of uplink and downlink channels, in the research of URLLC (Ultra-relaible and Low Latency Communication), only enhancing the downlink data channel cannot guarantee service performance. Therefore, in the research of R17 (Release 17), the downlink control channel PDCCH (Physical Downlink Control Channel) and the uplink control channel PUCCH (Physical Uplink Control Channel) and data channel PUSCH (Physical Uplink Shared Channel) will continue to be enhanced.

[0005] Taking PUSCH as an example, repeated transmission of PUSCH can be used for enhancement. The current PUSCH enhancement methods are all for a single TRP and are not applicable in multi-TRP scenarios. Summary of the invention

[0076] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0077] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0078] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0079] Before introducing the channel transmission solution provided by the present disclosure, two PUSCH enhancement methods in R15 and R16 are first introduced.

[0080] The first enhancement method is the repeated type A transmission method adopted in R15.

[0081] The repetition type A transmission mode is for the time slot level, Slot Aggregation (time slot aggregation) PUSCH transmission mode. Figure 1A As shown, a PUSCH is repeatedly transmitted at K consecutive transmission opportunities (nominal repetition). Figure 1A The value of K is 2. The transmission starts from the Sth symbol of the starting time slot, and each transmission opportunity lasts for L symbols. Figure 1A The value of L is 4.

[0082] The main thing is that (S+L) does not exceed the time slot boundary. For example, a time slot includes 14 time symbols, so (S+L) does not exceed 14.

[0083] The repetitive type A transmission mode is not suitable for services with low latency requirements and high reliability requirements.

[0084] The second enhanced method is the repeated type B transmission method adopted in R16.

[0085] In order to be suitable for services with low latency requirements and high reliability requirements, R16 proposes a PUSCH repetition transmission method based on mini-slots, namely, repetition type B transmission method, which allows PUSCH repetition transmission across time slots, thereby further reducing latency.

[0086] In the time domain, a PUSCH starts transmission at the Sth symbol in the starting time slot, and sends K transmission opportunities continuously. Each transmission opportunity occupies L symbols continuously. For example Figure 1B shown.

[0087] Meanwhile, in the repetition type B transmission mode, (S+L) can cross the time slot boundary. When the transmission opportunity crosses the time slot boundary, the transmission opportunity is re-divided to obtain the actual transmission opportunity (actual repetition) K'. Figure 1C and Figure 1D shown.

[0088] exist Figure 1C In the example, the third transmission opportunity is divided into two actual transmission opportunities again by the time slot boundary because it crosses the time slot boundary. Figure 1C In the example, the transmission timing K of PUSCH is 4, but the actual transmission timing K' is 5.

[0089] exist Figure 1D In the transmission time slot, there is only one transmission opportunity, which is divided into two actual transmission opportunities by the time slot boundary because it crosses the time slot boundary. Figure 1D In the example, the transmission timing K of PUSCH is 1, but the actual transmission timing K' is 2.

[0090] The base station can indicate that the semi-static Flexible time symbol is a dynamic uplink symbol or a dynamic downlink symbol through SFI (Slot Format Indicator). Therefore, the semi-static Flexible time symbol may be an available symbol for PUSCH (i.e., the Flexible time symbol is an uplink signal and can be used for PUSCH transmission), or it may be an unavailable symbol (i.e., the Flexible time symbol is a downlink signal and cannot be used for PUSCH transmission). When there are unavailable time symbols, it is necessary to drop (discard) the unavailable time symbols and transmit PUSCH on the remaining available symbols. That is, for the entire transmission, the time slot L×K can represent the time window size of PUSCH transmission. If a time symbol appears in the time window and cannot be transmitted uplink, then the time symbol cannot transmit PUSCH, and the transmission opportunity needs to be dropped (discarded) and PUSCH is transmitted on other transmission opportunities.

[0091] The values ​​corresponding to the above-mentioned repetition type A transmission mode and repetition type B transmission mode are shown in Table 1:

[0092] Table 1

[0093]

[0094]

[0095] In the above-mentioned repetition type A transmission mode and repetition type B transmission mode, it is applicable to a single RTP scenario and does not support the terminal to use multiple TRP technology to repeatedly transmit PUSCH to improve data transmission reliability.

[0096] In addition, currently when repeatedly transmitting PUSCH, it is necessary to determine the corresponding RV (Redundancy Version) sequence. The method for determining the RV sequence is shown in Table 2:

[0097] Table 2

[0098]

[0099] Corresponding to the above-mentioned repetition type A transmission mode, the RV sequence is directly mapped on all transmission opportunities, the base station sends DCI (Downlink Control Information, downlink control information), and indicates the initial value of the RV sequence through the RV information field of the DCI. For example, the RV information field in the DCI is 2 bits, and the bit value is 10, which corresponds to the RV sequence 2, 3, 1, 0 with an initial value of 2 in Table 2.

[0100] Corresponding to the above-mentioned repetition type B transmission mode, the RV sequence is directly mapped to all actual transmission opportunities. The base station also sends DCI (Downlink Control Information) and indicates the initial value of the RV sequence through the RV information field of the DCI.

[0101] In order to support multiple TPR scenarios when repeatedly transmitting PUSCH, it is necessary to consider the mapping between different RV transmission parameters and different transmission opportunities, but this is not involved in the current solution.

[0102] In order to solve the above problems, the present disclosure provides a channel transmission solution, which can apply the allocation of RV parameters to support multiple TRP transmissions when repeatedly transmitting PUSCH.

[0103] The present disclosure provides a channel transmission method, which can be used in a terminal. Figure 2 As shown, Figure 2 is a flow chart of a channel transmission method according to an embodiment, and the method may include the following steps:

[0104] In step 201, a mapping relationship between at least one basic RV sequence and a plurality of candidate transmission opportunities for sending a physical uplink data channel PUSCH is determined.

[0105] In step 202, an actual RV sequence corresponding to each candidate transmission opportunity among the multiple candidate transmission opportunities is determined according to the at least one basic RV sequence.

[0106] In the embodiment of the present disclosure, the actual RV sequence refers to the RV sequence for sending PUSCH obtained by cyclic mapping according to the basic RV sequence corresponding to the corresponding candidate transmission opportunity. For example, the basic RV sequence is 0, 2, 3, 1, and the actual RV sequence can be an RV sequence obtained by cyclic mapping of any sequence in Table 2. For example, the corresponding RV sequence value corresponding to 4 transmission configurations can be 2, 3, 1, 0 or 1, 0, 2, 3.

[0107] In step 203, the data blocks of the PUSCH are repeatedly sent at multiple target transmission occasions based on the actual RV sequences corresponding to the corresponding target transmission occasions.

[0108] In the above embodiment, the terminal can determine the mapping relationship between at least one basic RV sequence and multiple alternative transmission opportunities for sending PUSCH. According to at least one base station RV sequence, the actual RV sequence corresponding to each alternative transmission opportunity is determined, so that at multiple target transmission opportunities, the data block of the PUSCH is repeatedly sent based on the actual RV sequence corresponding to the corresponding target transmission opportunity. The present disclosure achieves the purpose of supporting multiple TRP transmissions by allocating RV parameters while repeatedly transmitting PUSCH, thereby improving the reliability of data transmission.

[0109] In an optional embodiment, for the above step 201, when determining the mapping relationship, it can be determined according to the first signaling sent by the base station, or it can be determined according to the settings predefined in the protocol. The first signaling can be a high-level RRC (Radio Resource Control) signaling, or a MAC (Media Access Control Address) signaling, which is not limited in the present disclosure.

[0110] In the above embodiment, the mapping relationship may be configured by the base station, or the mapping relationship may be predefined in the protocol, which is easy to implement and has high availability.

[0111] In an optional embodiment, the mapping relationship may be determined in any one of the following ways.

[0112] The first method is to determine the mapping relationship based on a first corresponding relationship between different beam indication information received by different sending and receiving points TRP of the corresponding base station and the multiple alternative transmission opportunities.

[0113] Reference Figure 3 As shown, Figure 3 is based on Figure 2 In the flowchart of another channel transmission method shown in the embodiment, step 201 may include:

[0114] In step 201-11, a first correspondence between different beam indication information received by different sending and receiving points TRP of the corresponding base station and the multiple alternative transmission opportunities is determined.

[0115] The beam indication information is beam related information used for uplink data channel PUSCH transmission. In the disclosed embodiment, the beam indication information may include spatial relation information, or include UL (Up Link) TCI (Transmission Configuration Indicator) state information.

[0116] In step 201-12, the mapping relationship is determined according to the basic RV sequence corresponding to the different beam indication information and the first corresponding relationship.

[0117] In an embodiment of the present disclosure, different beam indication information may correspond to the same basic RV sequence or different basic RV sequences. The terminal may determine a mapping relationship between at least one basic RV sequence and multiple alternative transmission opportunities for sending a physical uplink data channel PUSCH based on the basic RV sequences corresponding to different beam indication information and the above-mentioned first correspondence.

[0118] In the above embodiment, the mapping relationship can be determined according to the first corresponding relationship between the above different beam indication information and multiple alternative transmission opportunities, which is simple to implement and has high availability.

[0119] In an alternative embodiment, referring to Figure 4 As shown, Figure 4 is based on Figure 3 In the flowchart of another channel transmission method shown in the embodiment, step 202 may include:

[0120] In step 202-1, the plurality of candidate transmission opportunities are divided into a plurality of groups.

[0121] Each group of candidate transmission opportunities corresponds to the same beam indication information. For example, the multiple candidate transmission opportunities include two groups of candidate transmission opportunities, the first group of candidate transmission opportunities corresponds to beam indication information TCI-1, and the second group of candidate transmission opportunities corresponds to beam indication information TCI-2.

[0122] In step 202-2, a basic RV sequence corresponding to each group of candidate transmission opportunities is determined.

[0123] In the embodiment of the present disclosure, each group of candidate transmission opportunities may correspond to a basic RV sequence, and multiple groups of candidate transmission opportunities may correspond to the same or different basic RV sequences. In the embodiment of the present disclosure, the base station may inform the terminal of the basic RV sequence corresponding to each group of candidate transmission opportunities through the second signaling, or predefine the basic RV sequence corresponding to each group of candidate transmission opportunities in the protocol.

[0124] For example, the two groups of candidate transmission opportunities may correspond to the same group of basic RV sequences, which are {0, 2, 3, 1}. Or the two groups of candidate transmission opportunities may correspond to two different groups of basic RV sequences, for example, the first group of candidate transmission opportunities corresponds to the basic RV sequence 0, 2, 3, 1, and the second group of candidate transmission opportunities corresponds to the basic RV sequence 0, 3, 0, 3, and the two basic RV sequences are different.

[0125] In step 202-3, the initial value or sequence offset value of the actual RV sequence corresponding to each group of candidate transmission opportunities is determined.

[0126] In the disclosed embodiment, the initial value of the actual RV sequence corresponding to each group of candidate transmission opportunities can be directly determined, and the initial value can be a value in the basic RV sequence, indicating the value of the actual RV sequence starting from the basic sequence. For example, the basic RV sequence is {0, 2, 1, 3}, and the initial value is 2, indicating that the first actual RV sequence value is 2, and the subsequent actual RV sequences are cyclically mapped according to the basic RV sequence to obtain 2, 1, 3, 0, 2, ...

[0127] Or the terminal may determine the sequence offset value of the actual RV sequence corresponding to each set of alternative transmission opportunities. The sequence offset value is the starting position of the RV sequence for cyclic mapping of each set of alternative transmission opportunities relative to the basic RV sequence. For example, the basic RV sequence is 0, 2, 1, 3, the sequence offset value is 3, and the default offset reference point is a value of the RV sequence, which means that the starting value of the first RV sequence value of the actual RV sequence is 3, and the subsequent actual RV sequences are cyclically mapped according to the basic sequence to obtain 3, 0, 2, 1, 3, ... .

[0128] In step 202-4, a plurality of actual RV sequences corresponding to each group of candidate transmission opportunities are determined according to the basic RV sequence corresponding to each group of candidate transmission opportunities and the initial value of the actual RV sequence or the sequence offset value.

[0129] For example, the basic RV sequence is 0, 2, 1, 3, and the initial value of the first RV sequence value of the basic RV sequence is 1. Then, the subsequent actual RV sequences are cyclically mapped according to the basic sequence to obtain 1, 3, 0, 2, 1, ...

[0130] For another example, the basic RV sequence is 0, 2, 1, 3, the sequence offset value is 2, and the default offset reference point is a value of the RV sequence, which means that the starting value of the actual RV sequence is 1 for the first RV sequence value of the basic RV sequence, and the subsequent actual RV sequences are cyclically mapped according to the basic sequence to obtain 1, 3, 0, 2, 1, ... In the above embodiment, the actual RV sequence corresponding to each alternative transmission opportunity can be determined according to the above mapping relationship and at least one basic RV sequence, so as to repeat the transmission of PUSCH at multiple target transmission opportunities. While achieving repeated transmission of PUSCH, the allocation of RV parameters is applied to support the purpose of multi-TRP transmission, thereby improving the reliability of data transmission.

[0131] In an optional embodiment, the above step 202-3 may be implemented in the following manner:

[0132] The initial value or the sequence offset value of the actual RV sequence corresponding to each group of candidate transmission opportunities is determined according to the designated information field included in the downlink control instruction DCI sent by the base station.

[0133] In the embodiment of the present disclosure, the initial value or the sequence offset value of the actual RV sequence corresponding to each set of candidate transmission opportunities may be notified to the terminal through the designated information field included in the DCI (Downlink Control Information), wherein the designated information field may adopt the RV field in the DCI.

[0134] The RV field included in the existing DCI includes 2 bits and can only be used for the initial value of an actual RV sequence corresponding to one beam indication information.

[0135] In one example, the RV field of the DCI may be extended, and the initial value of the actual RV sequence corresponding to each group of candidate transmission opportunities may be independently indicated through the RV field.

[0136] For example, if there are two groups of alternative transmission opportunities, the RV field can be extended to 4 bits, the first 2 bits are used to indicate the initial value of the actual RV sequence corresponding to the first group of alternative transmission opportunities, and the last 2 bits are used to indicate the initial value of the actual RV sequence corresponding to the second group of alternative transmission opportunities.

[0137] Taking two groups of alternative transmission opportunities corresponding to the same basic sequence 0, 2, 3, 1 as an example, the bit value of the RV field is 1001, indicating that the initial value of the actual RV sequence corresponding to the first group of alternative transmission opportunities is 2, and the initial value of the actual RV sequence corresponding to the second group of alternative transmission opportunities is 1.

[0138] In another example, the RV field may not be extended, and the RV field is used to indicate the corresponding code point RVcodepoint of the associated information associated with the initial value of the actual RV sequence or the sequence offset value corresponding to each group of alternative transmission opportunities.

[0139] Optionally, a second corresponding relationship between the RV codepoint and the initial value of the RV sequence may be predetermined, as shown in Table 3, for example.

[0140] Table 3

[0141] RV codepoint Initial value of RV1 sequence Initial value of RV2 sequence 0 0 2 1 1 3 2 2 0 3 3 1

[0142] The base station can send a 2-bit value through the RV field of DCI, assuming it is 10. According to Table 3, the terminal can determine that the value 2 corresponds to the initial value of the actual RV sequence corresponding to the first group of alternative transmission opportunities, which is 2, and the initial value of the actual RV sequence corresponding to the second group of alternative transmission opportunities is 0.

[0143] Alternatively, the terminal may predetermine a third corresponding relationship between the RV codepoint and the sequence offset value, such as shown in Table 4.

[0144] Table 4

[0145]

[0146]

[0147] The base station can still send a 2-bit value through the RV field of the DCI, assuming that it is also 10. The terminal determines from Table 4 that the value 2 corresponds to the sequence offset of the actual RV sequence corresponding to the first group of candidate transmission opportunities, which is 2, and the sequence offset of the actual RV sequence corresponding to the second group of candidate transmission opportunities is 0. Correspondingly, if the basic sequences are all 0, 2, 3, and 1, then the first actual RV sequence corresponding to the first group of candidate transmission opportunities is 3, 1, 0, and 2, and the subsequent opportunity RV sequences are cycled in sequence, and the first actual RV sequence corresponding to the second group of candidate transmission opportunities is 0, 2, 3, and 1, and the subsequent opportunity RV sequences are cycled in sequence.

[0148] In the embodiment of the present disclosure, the second correspondence relationship and the third correspondence relationship in Table 3 and Table 4 may be configured by the base station through a third signaling, or may be predefined in the protocol. The third signaling may be an RRC signaling or a MAC signaling.

[0149] In another example, the RV field may also be used for an initial value of a first RV sequence in an actual RV sequence relative to the first beam indication information in each set of candidate transmission opportunities, wherein the RV sequence corresponding to the first beam indication information is the first RV sequence.

[0150] When the designated information field is used to indicate the initial value of the first RV sequence in the actual RV sequence corresponding to the first beam indication information in each group of alternative transmission opportunities, the offset value of the initial value of other RV sequences in the actual RV sequence corresponding to each group of alternative transmission opportunities relative to the initial value of the first RV sequence can be determined. Furthermore, the base station can determine the initial values ​​of the other RV sequences respectively according to the initial value of the first RV sequence and the offset value. The offset value refers to the offset value of the initial value of the other RV sequences relative to the initial value of the first RV sequence, and the offset value can be configured by the base station through a fourth signaling, or predefined in the protocol, wherein the fourth signaling can be RRC signaling or MAC signaling.

[0151] For example, the initial value of the first RV sequence is RV1, and the offset value offset can be determined according to the fourth signaling or protocol preconfiguration. For example, the initial values ​​of other RV sequences are obtained according to the formula RV2=mod(RV1+offset, 4).

[0152] In an optional embodiment, in the above solution, the multiple groups of candidate transmission opportunities correspond to the same basic RV sequence. If the multiple groups of candidate transmission opportunities correspond to different basic RV sequences, the method may be:

[0153] Multiple basic RV sequences are informed of the terminal in advance through the second signaling. For example, the basic RV sequence is [RV1, RV2]. By extending the RV field of the DCI, two groups of alternative transmission opportunities can be indicated to correspond to the initial values ​​of different basic sequences respectively. For example, if the bit value of the RV field is 0010, the first group of alternative transmission opportunities corresponds to the initial value 0 in RV1, and the second group of alternative transmission opportunities corresponds to the initial value 2 in RV2.

[0154] If the RV field of the DCI is not extended, Table 3 or Table 4 can be determined by a third signaling or protocol predefined method. The terminal can query Table 3 or Table 4 according to the value of the RV field to determine the initial value or sequence offset value of the actual RV sequence corresponding to different groups of alternative transmission opportunities. Assuming that RV1 is {0, 2, 3, 1], RV2 is {0, 3, 0, 3}, and the value of the RV field of the DCI is 01, then according to Table 3, it can be obtained that the initial value of the actual RV sequence corresponding to the first group of alternative transmission opportunities is 1, that is, the first actual RV sequence is 1, 0, 2, 3. The initial value of the actual RV sequence corresponding to the second group of alternative transmission opportunities is 3, that is, the first actual RV sequence is 3, 0, 3, 0.

[0155] The method of determining the sequence offset value according to Table 4 is similar to the above method and will not be described in detail here.

[0156] In an optional embodiment, corresponding to the above-mentioned repeated type A transmission mode, the multiple candidate transmission opportunities may include K1 nominal transmission opportunities.

[0157] The K1 nominal transmission opportunities are respectively located in different time slots, the starting symbol positions of the K1 nominal transmission opportunities in each time slot are the same, and the number of continuous symbols in each time slot is the same.

[0158] If there is a first transmission opportunity among the K1 nominal transmission opportunities, the multiple target transmission opportunities include multiple second transmission opportunities, wherein the first transmission opportunity is a transmission opportunity when uplink PUSCH cannot be sent, and the multiple second transmission opportunities are transmission opportunities among the K1 nominal transmission opportunities when uplink PUSCH can be sent.

[0159] Similarly, for the above-mentioned repetitive type A transmission mode, multiple alternative transmission opportunities can directly include K1' actual transmission opportunities; wherein the K1' actual transmission opportunities are transmission opportunities in the K1 nominal transmission opportunities for uplink PUSCH transmission, the K1 nominal transmission opportunities are respectively located in different time slots, the starting symbol positions of the K1 nominal transmission opportunities in each time slot are the same, and the number of continuous symbols in each time slot is the same.

[0160] Further, the multiple target transmission opportunities include the K1' actual transmission opportunities.

[0161] Corresponding to the above-mentioned repeated type B transmission mode, the multiple alternative transmission opportunities may include K2' actual transmission opportunities; wherein the K2' actual transmission opportunities are multiple actual transmission opportunities obtained by dividing the K2 nominal transmission opportunities, and the K2 nominal transmission opportunities are transmission opportunities allocated continuously back to back.

[0162] Correspondingly, the multiple target transmission opportunities include the multiple second actual transmission opportunities, wherein the multiple second actual transmission opportunities are transmission opportunities in which uplink PUSCH transmission can be performed among the K2' actual transmission opportunities.

[0163] Also corresponding to the above-mentioned repetition type B transmission mode, the multiple alternative transmission opportunities may include K2" actual transmission opportunities; wherein the K2" actual transmission opportunities are transmission opportunities for uplink PUSCH transmission among the K2' actual transmission opportunities; the K2' actual transmission opportunities are actual transmission opportunities obtained by dividing the K2 nominal transmission opportunities; the K2 nominal transmission opportunities are continuous transmission opportunities allocated back to back.

[0164] Further, the multiple target transmission opportunities include the K2" actual transmission opportunities.

[0165] In the above embodiment, the terminal can determine the mapping relationship between at least one basic RV sequence and multiple alternative transmission opportunities based on the correspondence between different beam indication information and multiple alternative transmission opportunities, thereby determining the actual RV sequence corresponding to each of the multiple alternative transmission opportunities. Furthermore, the terminal can repeatedly send the data block of the PUSCH at multiple target transmission opportunities, based on the actual RV sequence corresponding to the corresponding target transmission opportunity. This achieves the purpose of supporting multiple TRP transmissions by allocating RV parameters while repeatedly transmitting PUSCH, thereby improving the reliability of data transmission.

[0166] In an optional embodiment, the above mapping relationship may also be determined in the following manner.

[0167] The second method does not distinguish the first corresponding relationship between different beam indication information and multiple alternative transmission opportunities, and directly determines the mapping relationship between at least one basic RV sequence and all alternative transmission opportunities for sending PUSCH.

[0168] Accordingly, the multiple candidate transmission opportunities may include all nominal transmission opportunities, and accordingly, the multiple target transmission opportunities include all actual transmission opportunities in which uplink PUSCH transmission can be performed among all nominal transmission opportunities.

[0169] Alternatively, the multiple candidate transmission opportunities include all actual transmission opportunities where uplink PUSCH transmission can be performed, and the multiple target transmission opportunities also include all transmission opportunities.

[0170] In the above embodiment, the first correspondence between the beam indication information and the alternative transmission timing can be ignored, and the basic RV sequence and multiple alternative transmission timings can be directly mapped. Similarly, while repeatedly transmitting PUSCH, the allocation of RV parameters is applied to support the purpose of multiple TRP transmission, thereby improving the reliability of data transmission.
