Description

Technical Field

[0001] The present invention relates to the technical field of communications.

Background Art

[0002] In order to simultaneously meet the needs of high reliability and low latency of URLLC (Ultra Reliable Low Latency Communications) services, a corresponding uplink data transmission mechanism has been introduced in NR Rel-16 (New Radio Release 16). Since this mechanism can support more flexible uplink data transmission, it can ensure that uplink data is transmitted in a low-latency manner.

[0003] Note that the introduction of the above background art is for clearly and completely explaining the technical solution of the present invention and for facilitating understanding by those skilled in the art. These technical solutions should not be construed as well-known to those skilled in the art just because they are described in the background art of the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventors have discovered the following. That is, NR (New Radio) can support carrier frequencies up to 52.6 GHz. When the carrier frequency is relatively high, the diffraction ability of high-frequency signals is relatively low, so they are easily blocked by obstacles. When the transmission path is blocked, the corresponding transmission channel quality drops significantly. This may lead to a decrease in the reliability of the transmission signal and / or an increase in transmission latency. This is very disadvantageous for URLLC services. In particular, when the signal blocking becomes severe to a certain extent, ongoing URLLC services may be forced to be interrupted or fail. This is because when applying the existing uplink scheduling mechanism, it takes at least several tens of milliseconds for the terminal device to recover the communication link, while the communication latency of URLLC is usually much smaller than several tens of milliseconds. Therefore, after a link failure, the URLLC service packets being transmitted will fail due to timeout before the communication link is recovered.

[0005] To reduce the impact of the instability of the above-mentioned high-frequency transmission channel on uplink data transmission, as one feasible method, there is a way to transmit uplink data in a spatial diversity manner. That is, on the UE side, the same data can reach the base station via different spatial domain paths (or it can also be said as "via different TRPs (transmission and reception points)"). In this way, even if blocking occurs in one path, other paths can still continue to work, thus ensuring the high reliability of uplink data and effectively reducing the impact of channel instability on transmission latency.

[0006] Also, to improve the merge gain, data transmission can usually correspond to a specific RV (redundancy version). However, when data is transmitted via multiple TRPs, there is no way to indicate the relationship between the corresponding data transmission and the redundancy version, especially the relationship between data transmission in the PUSCH repetition type A or PUSCH repetition type B mode and the redundancy version.

[0007] Regarding uplink data transmission, by performing frequency hopping during transmission, the frequency-domain diversity gain can be effectively utilized to improve the system performance. However, currently, in a multi-TRP scenario, especially in a scenario where uplink data is transmitted to different TRPs in the PUSCH repetition type A or PUSCH repetition type B mode, there is still no way to realize the frequency hopping of uplink data.

[0008] To solve at least one of the above problems or other similar problems, embodiments of the present invention provide a method, an apparatus, and a system for transmitting uplink data. Thereby, when uplink data is transmitted via multiple TRPs, by transmitting according to the corresponding RV, the reliability of uplink data transmission can be improved, or by transmitting according to the corresponding frequency hopping pattern, uplink data transmission can be made to fully utilize the frequency-domain diversity gain, so the reliability can also be improved.

[0033] To make the embodiments of the present invention easier to understand, several concepts and definitions related to the embodiments of the present invention will be described below.

[0034] Hereinafter, PUSCH repetition Type A will be described.

[0035] In an embodiment of the present invention, PUSCH repetition Type A is an uplink data transmission method based on slots. One PUSCH (Physical Uplink Shared Channel) transmitted in the PUSCH repetition Type A manner may correspond to one or more repetitions or transmission occasions, which are denoted as repetition#1, repetition#2, …, repetition#m, where m = 1, 2, 3…, K, and K is the number of repetitions of the PUSCH. When K > 1, there is one repetition in each of the consecutive K slots, and these repetitions have the same time domain / symbol allocation method. Also, these repetitions correspond to the same TB (Transmission Block). Specifically, the PUSCH may be indicated by the following parameters, that is, The start slot of the PUSCH (denoted as Ks); The start symbol of the time domain of the PUSCH (denoted as S); The time domain length of each repetition (denoted as L) (the unit of this length is a symbol); and The number of repetitions (K) (the number of repetitions is, for example, 1, 2, 4, 7, 16, but the number of repetitions may also be 2, 4, 8. The present invention is not limited to these, and the number of repetitions may be other positive integers) That's it.

[0036] Note that the above-mentioned S and L may be indicated respectively, or may be jointly indicated by a start and length indicator (also referred to as an indicator or indication ID, SLIV).

[0037] FIG. 1 is a diagram showing an example of a dynamically scheduled PUSCH. As shown in FIG. 1, after receiving one PUSCH transmission instruction (e.g., PDCCH), the UE transmits the corresponding PUSCH. Among them, the specific parameters are as follows, that is, Ks = k (k may be, for example, 0, 1, 2...) S = 0; L = 10; and K = 2 That is.

[0038] In the example of FIG. 1, the time domain resource mapping method (PUSCH mapping type) of the PUSCH is PUSCH mapping tpye A, the DM-RS (Demodulation Reference Signal) starts from the third symbol of each slot, and the corresponding phase-tracking reference signal (PT-RS) is set. Since K = 2, the first repetition of the PUSCH (or it can also be said as "the first transmission opportunity") is in slot n + k, and the second repetition of this PUSCH (or it can also be said as "the second transmission opportunity") is in slot n + k + 1.

[0039] FIG. 2 is a diagram showing an example of a configured grant PUSCH. As shown in FIG. 2, the UE determines that it can start transmitting the PUSCH in slot n + k (that is, there is a PUSCH transmission opportunity starting from slot n + k) based on the CG setting corresponding to the PUSCH and / or the instruction of the activation DCI regarding the PUSCH. The corresponding other parameters are as follows, that is, S = 0; L = 10; and K = 2 That is.

[0040] In the example of FIG. 2, the PUSCH time domain resource mapping type of the PUSCH is PUSCH mapping type A, the DM-RS starts from the third symbol of each slot, and the corresponding PT-RS is set. Since K = 2, the first repetition (or "the first transmission opportunity") of the above-mentioned PUSCH is in slot n + k, and the second repetition (or "the second transmission opportunity") of the above-mentioned PUSCH is in slot n + k + 1.

[0041] Hereinafter, PUSCH repetition Type B will be described.

[0042] In an embodiment of the present invention, PUSCH repetition Type B is a low-latency uplink data transmission method. One PUSCH transmitted in the manner of PUSCH repetition Type B may correspond to one or more nominal repetitions (or "transmission opportunities of one or more nominal repetitions"), which are denoted as nominal repetition#1, nominal repetition#2,..., nominal repetition#n, where n = 1, 2, 3,..., N, and N is the number of nominal repetitions of the PUSCH. Specifically, the PUSCH may be indicated by the following parameters, that is, The start slot of the PUSCH (denoted as Ks); The time domain start symbol of the PUSCH (denoted as S); The time domain start point, time domain end point, and time domain length for PUSCH nominal repetition#n (the slot corresponding to the time domain start point is

[0047] After the UE determines the time domain resource corresponding to the nominal repetition based on the above parameters, it is further necessary to determine the corresponding actual repetition based on the slot boundary and Invalid symbol(s). The determination method is as follows, that is, in one slot, if the number of potentially valid symbols other than the invalid symbol corresponding to one nominal repetition is greater than 0 (zero), the nominal repetition consists of one or more actual repetitions. Among them, each actual repetition consists of all the consecutive potential valid symbols.

[0048] Note that the invalid symbol includes the symbol indicated for the downlink by upper layer signaling. Here, the upper layer signaling may be the cell-specific uplink / downlink TDD (Time Division Duplexing) configuration, for example, tdd-UL-DL-ConfigurationCommon, or the upper layer signaling may be the UE-specific uplink / downlink TDD configuration, for example, tdd-UL-DL-ConfigurationDedicated.

[0049] Alternatively, the invalid symbol may include the symbol corresponding to the invalid symbol pattern indicated by upper layer signaling. For type 2 configured grant or dynamically scheduled, it is possible to determine whether the invalid symbol pattern is valid based on the invalid symbol pattern indicator field in the DCI. For example, when the field is set to 1, the corresponding invalid symbol pattern is considered valid, and when the field is set to 0, the corresponding invalid symbol pattern is considered invalid.

[0050] Also, when L is not equal to 1 and the length of one actual repetition is 1 symbol, the actual repetition is omitted (or it may be said that "not transmitted"). When one actual repetition collides with the slot format, for example, when one flexible symbol is decoded / indicated as a DL symbol according to the DCI instruction, the actual repetition is omitted (or it may be said that "not transmitted").

[0051] Figure 3 is a diagram showing an example of a dynamically scheduled PUSCH. As shown in Figure 3, after receiving one PUSCH transmission instruction (e.g., PDCCH), the UE transmits the corresponding PUSCH after at least T proc,2 After that, the corresponding PUSCH is transmitted. Among them, T proc,2 refers to the PUSCH preparation procedure time, and the other parameters are as follows, that is, Ks = k (k can be, for example, 0, 1, 2...); S = 2; L = 5; and N = 5 That's it.

[0052] In this example, the Slot format of each symbol is set by upper layer signaling. As shown in Figure 3, among them, D represents a downlink symbol, U represents an uplink symbol, F represents a flexible symbol, the PUSCH mapping type is PUSCH mapping type B, DM-RS starts from the first symbol of each actual repetition, and PT-RS is set.

[0053] In this example, the above-mentioned PUSCHs respectively correspond to 5 nominal repetitions and 6 actual repetitions (or it can also be said that "the above-mentioned PUSCH corresponds to the transmission opportunities of 5 nominal repetitions, or the above-mentioned PUSCH corresponds to the transmission opportunities of 6 actual repetitions"). The reason is as follows. That is, nominal repetition #3 straddles the slot boundary, and the first symbol of slot n + k + 1 is set as a DL symbol, that is, an invalid symbol. According to the above rules, since this symbol is not counted into the actual repetition, the nominal repetition #3 is divided into two parts (actual repetition #3 and actual repetition #4), each of which occupies two consecutive symbols.

[0054] Figure 4 is a diagram showing an example of a configured grant PUSCH. As shown in Figure 4, the UE can determine to start transmitting the PUSCH in slot n + k according to the CG setting corresponding to the PUSCH and / or the instruction of the activation DCI regarding the PUSCH (that is, there is a PUSCH transmission opportunity starting from slot n + k). The other corresponding parameters are as follows respectively, that is, S = 2; L = 5; and N = 5 respectively.

[0055] In this example, the slot format of each symbol is set by upper layer signaling. As shown in Figure 4, among them, D represents a downlink symbol, U represents an uplink symbol, F represents a flexible symbol, and DM-RS starts from the first symbol of each actual repetition and PT-RS is set.

[0056] In this example, the above-mentioned PUSCH transmissions respectively correspond to 5 nominal repetitions and 6 actual repetitions (or it can also be said that "the above-mentioned PUSCH corresponds to the transmission opportunities of 5 nominal repetitions, or the above-mentioned PUSCH corresponds to the transmission opportunities of 6 actual repetitions"). The reason is as follows. That is, nominal repetition #3 straddles the slot boundary, and the first symbol of slot n + k + 1 is set as a DL symbol, that is, an invalid symbol. According to the above rules, since this symbol is not included in the actual repetition, this nominal repetition #3 is divided into two parts (actual repetition #3 and actual repetition #4), and each occupies two consecutive symbols.

[0057] In the present invention, a multi-TRP transmission scheme is provided for two different uplink data transmission methods (PUSCH repetition Type A and PUSCH repetition Type B) respectively.

[0058] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that these embodiments are merely illustrative and do not limit the present invention.

[0059] <Embodiment of the first aspect> In an embodiment of the present invention, a method for transmitting uplink data is provided and described from the perspective of the terminal device. The method of the embodiment of the present invention is applicable to uplink data (PUSCH) transmitted in the PUSCH repetition type B manner, and the description will be made by taking the scenario of the dynamically scheduled PUSCH shown in FIG. 3 and the scenario of the configured grant PUSCH shown in FIG. 4 as examples.

[0060] FIG. 5 is a diagram showing a method for transmitting uplink data in an embodiment of the present invention. As shown in FIG. 5, the method includes the following steps.

[0061] 501: The terminal device transmits uplink data in the PUSCH repetition type B manner, at least one transmission opportunity of the uplink data is associated with two TRPs, and the RV of at least one transmission opportunity of the uplink data is determined (derived) based on the two TRPs.

[0062] In an embodiment of the present invention, the transmission opportunity may be understood as a time-frequency resource, or may be understood as a repetition, and these concepts can be replaced with each other.

[0063] In an embodiment of the present invention, the transmission opportunity is equivalent to an actual repetition, or is also equivalent to the transmission opportunity of an actual repetition. Also, the transmission opportunity of a nominal repetition is equivalent to a nominal repetition, or is also equivalent to the transmission opportunity of an actual repetition corresponding to a nominal repetition.

[0064] According to the above method in an embodiment of the present invention, when blocking occurs, even if only some TRPs can work, it can be guaranteed to have a relatively high combining gain compared to the case where the RV is independent of the TRP. The reason is as follows. That is, by such a method, the RV of the above-mentioned uplink data transmission opportunity can be adjusted based on the information of the associated TRP. That is, when the TRPs corresponding to the above-mentioned uplink data transmission opportunities are different, or when a change occurs in the probability that the corresponding TRP is blocked, the RV of each transmission opportunity can be flexibly and optimally determined based on the associated information of the TRP, so that the system performance can be improved.

[0065] In some embodiments, that the RV of at least one transmission opportunity of the uplink data is derived by the above two TRPs means that, among at least one transmission opportunity of the uplink data, the RV of the transmission opportunity of the actual repetition associated with the first TRP of the above two TRPs is determined according to the time domain order of the actual repetition, and among at least one transmission opportunity of the uplink data, the RV of the transmission opportunity of the actual repetition associated with the second TRP of the above two TRPs is determined according to the time domain order of the actual repetition. That is, the RV sequence is cyclically mapped to the transmission opportunities of the actual repetition of the PUSCH.

[0066] In some embodiments, that the RV of at least one transmission opportunity of the uplink data is derived based on the above two TRPs means that, among at least one transmission opportunity of the uplink data, the RV of the transmission opportunity of the nominal repetition associated with the first TRP of the above two TRPs is determined according to the time domain order of the nominal repetition, and among at least one transmission opportunity of the uplink data, the RV of the transmission opportunity of the nominal repetition associated with the second TRP of the above two TRPs is determined according to the time domain order of the nominal repetition. That is, the RV sequence is cyclically mapped to the transmission opportunities of the nominal repetition of the PUSCH.

[0067] FIG. 6 is a diagram showing an example of the mapping relationship between a dynamically scheduled PUSCH and an RV sequence. As shown in FIG. 6, the mapping relationship between the PUSCH and the two TRPs is an inter-nominal-repetition TRP mapping, that is, the PUSCH is cyclically mapped (correlated) with the two TRPs in units of transmission occasions of the nominal repetitions (the PUSCH is cyclically mapped (correlated) with the two TRPs in units of transmission occasions of the nominal repetitions), and the RV sequence (which is {0, 2, 3, 1} in FIG. 6) is cyclically mapped to the transmission occasions of the actual repetitions of the PUSCH, that is, the mapping method of the RV sequence is actual-repetition based RV mapping.

[0068] In the example of FIG. 6, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are 0231. Also, the difference (offset) between the RV of the nth actual repetition (or "transmission occasion of the actual repetition") of the PUSCH related to TRP#1 and the RV of the nth actual repetition (or "transmission occasion of the actual repetition") of the PUSCH related to TRP#2 is rv s where n is a natural number. Also, the RV is cyclically mapped based on the actual repetitions or the transmission occasions of the actual repetitions related to each TRP. For the sake of convenience of explanation, hereinafter, it will be collectively referred to as "transmission occasion of the actual repetition".

[0069] FIG. 7 is a diagram showing another example of the mapping relationship between a dynamically scheduled PUSCH and an RV sequence. As shown in FIG. 7, the mapping relationship between the PUSCH and the two TRPs is the same as that in FIG. 6, which is abbreviated as inter-nominal-repetition TRP mapping, that is, the PUSCH performs cyclic mapping (association) with the two TRPs in units of the transmission opportunities of nominal repetitions, and the RV sequence (which is {0, 2, 3, 1} in FIG. 7) is cyclically mapped to the transmission opportunities of the nominal repetitions of the PUSCH, that is, the mapping method of the RV sequence is nominal-repetition based RV mapping.

[0070] In the example of FIG. 7, the same points as in the example of FIG. 6 are as follows, that is, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are 0231, and the difference (offset) between the RV of the nth nominal repetition (or it can also be said as "the transmission opportunity of the actual repetition corresponding to the nominal repetition") of the PUSCH related to TRP#1 and the RV of the nth nominal repetition (or it can also be said as "the transmission opportunity of the actual repetition corresponding to the nominal repetition") of the PUSCH related to TRP#2 is rv s where n is a natural number. Also, the RV is cyclically mapped based on the nominal repetitions related to each TRP or the transmission opportunities of the actual repetitions corresponding to the nominal repetitions. For the convenience of explanation, hereinafter, it is collectively referred to as "the transmission opportunity of the actual repetition corresponding to the nominal repetition".

[0071] FIG. 8 is a diagram showing another example of the mapping relationship between a dynamically scheduled PUSCH and an RV sequence. As shown in FIG. 8, the mapping relationship between the PUSCH and the two TRPs is an inter-actual-repetition TRP mapping, that is, the PUSCH performs a cyclic mapping (association) with the two TRPs in units of the transmission opportunities of the actual repetitions, and the RV sequence (which is {0, 2, 3, 1} in FIG. 8) is cyclically mapped to the transmission opportunities of the actual repetitions of the PUSCH, that is, the mapping method of the RV sequence is actual-repetition based RV mapping.

[0072] In the example of FIG. 8, the same points as in the examples of FIGS. 6 and 7 are as follows: that is, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are 0231, and the difference (offset) between the RV of the nth actual repetition (or it can also be said as "the transmission opportunity of the actual repetition") of the PUSCH related to TRP#1 and the RV of the nth actual repetition (or it can also be said as "the transmission opportunity of the actual repetition") of the PUSCH related to TRP#2 is rv s is. Also, the RVs are cyclically mapped based on the actual repetitions or the transmission opportunities of the actual repetitions related to each TRP. For the convenience of explanation, hereinafter, it will be collectively referred to as "the transmission opportunity of the actual repetition".

[0073] FIG. 9 is a diagram showing an example of the mapping relationship between the configured grant PUSCH and the RV sequence. As shown in FIG. 9, the mapping relationship between the PUSCH and the two TRPs is nominal inter-repetition TRP mapping, that is, the PUSCH performs cyclic mapping (association) with the two TRPs in units of nominal repetition transmission opportunities, and the RV sequence (which is {0, 2, 3, 1} in FIG. 9) is cyclically mapped to the actual repetition transmission opportunities of the PUSCH. That is, the mapping method of the RV sequence is actual-repetition based RV mapping.

[0074] In the example of FIG. 9, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are 0231. Also, the difference (offset) between the RV of the n-th actual repetition (or "actual repetition transmission opportunity") of the PUSCH related to TRP#1 and the RV of the n-th actual repetition (or "actual repetition transmission opportunity") of the PUSCH related to TRP#2 is rv s is. Also, the RV is cyclically mapped based on the actual repetition or the actual repetition transmission opportunity associated with each TRP. For convenience of explanation, hereinafter, it will be collectively referred to as "actual repetition transmission opportunity".

[0075] FIG. 10 is a diagram showing another example of the mapping relationship between the configured grant PUSCH and the RV sequence. As shown in FIG. 10, the mapping relationship between the PUSCH and the two TRPs is an inter-nominal-repetition TRP mapping, that is, the PUSCH performs cyclic mapping (association) with the two TRPs in units of the nominal repetition transmission opportunities, and the RV sequence ({0, 3, 0, 3} in FIG. 10) is cyclically mapped to the actual repetition transmission opportunities of the PUSCH, that is, the mapping method of the RV sequence is actual-repetition based RV mapping.

[0076] In the example of FIG. 10, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are 0303. Also, the difference (cyclic shift) between the RV of the nth actual repetition (or "actual repetition transmission opportunity") of the PUSCH associated with TRP#1 and the RV of the nth actual repetition (or "actual repetition transmission opportunity") of the PUSCH associated with TRP#2 is RVshift. Also, the RV is cyclically mapped based on the actual repetition or the actual repetition transmission opportunity associated with each TRP. For the convenience of explanation, hereinafter, it will be collectively referred to as "actual repetition transmission opportunity".

[0077] FIG. 11 is a diagram showing another example of the mapping relationship between the configured grant PUSCH and the RV sequence. As shown in FIG. 11, the mapping relationship between the PUSCH and the two TRPs is an inter-nominal-repetition TRP mapping, that is, the PUSCH performs a cyclic mapping (association) with the two TRPs in units of the nominal repetition transmission opportunities, and the RV sequence (which is {0, 0, 0, 0} in FIG. 11) is cyclically mapped to the actual repetition transmission opportunities of the PUSCH. That is, the mapping method of the RV sequence is actual-repetition based RV mapping.

[0078] In the examples of FIGS. 9 to 11, only the case where the mapping relationship between the PUSCH and the two TRPs is an inter-nominal repetition TRP mapping is taken as an example, but the present invention is not limited thereto, and the mapping method of the TRP may be an inter-actual repetition TRP mapping. Also, the mapping method of the RV sequence may be a nominal-repetition based RV mapping in addition to the actual-repetition based RV mapping. Note that the present invention is not limited to these, and for specific implementation methods, reference can be made to the implementation of FIG. 7.

[0079] In embodiments of the present invention, in some embodiments, the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data, where the first transmission opportunity refers to the transmission opportunity among the transmission opportunities of the uplink data that is related to the first TRP among the above two TRPs, and the second transmission opportunity refers to the transmission opportunity among the transmission opportunities of the uplink data that is related to the second TRP among the above two TRPs. That is, among the transmission opportunities of the uplink data, the RV of the transmission opportunity related to TRP#1 (the first transmission opportunity) is related to the RV of the transmission opportunity related to TRP#2 (the second transmission opportunity). Thereby, the terminal device can utilize the relationship between the two to improve the combined gain of the uplink data. The reason is as follows. That is, compared with the case where there is no relevance between the transmission opportunities related to different TRPs, since the RV of the transmission opportunity related to TRP#1 is related to the RV of the transmission opportunity related to TRP#2, the transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 are adjacent in the time domain, and in a scenario where the probability of blocking is relatively low (that is, the probability of simultaneously receiving the adjacent transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 is relatively high), a higher combined gain can be achieved by optimizing the corresponding RV.

[0080] In some embodiments, the sequence number related to the first transmission opportunity is the same as the sequence number related to the second transmission opportunity. Here, the sequence number may be the nominal repetition sequence number corresponding to the transmission opportunity, or may be the actual repetition sequence number corresponding to the transmission opportunity.

[0081] In some embodiments, the RV of the first transmission opportunity of the uplink data being related to the RV of the second transmission opportunity of the uplink data means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling. Thereby, the network device can semi-statically adjust the RV of the transmission opportunity of the PUSCH corresponding to TRP#2 by RRC signaling according to the actual situation, so as to improve the merging gain of the corresponding uplink data signal, and thus improve the system performance.

[0082] In the above embodiments, the difference may be an offset, for example, the rv shown in FIGS. 6 to 9. s Or it may refer to a shift, for example, the RV shift shown in FIG. 10.

[0083] In some embodiments, the RV of the first transmission opportunity of the uplink data being related to the RV of the second transmission opportunity of the uplink data means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by DCI signaling. Thereby, the network device can flexibly indicate the corresponding RV based on each transmission of the PUSCH, so as to obtain the maximum merging gain.

[0084] The above embodiments are applicable to the PUSCH that is dynamically scheduled, for example, the scenarios shown in FIGS. 6 to 8.

[0085] For example, the above difference is indicated by the corresponding unit in the TDRA field of the above DCI signaling. Thereby, since there is no need to increase the additional DCI field, the size of the DCI can be reduced, and the reliability of the control channel can be improved.

[0086] Also, for example, the above difference is indicated by one field in the DCI signaling. Thereby, the indication is simple, the difficulty and cost of implementation are relatively low, so the impact on standardization is relatively small.

[0087] In some embodiments, that the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data means that the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity. Since such a method does not require additional instructions, it can save the overhead of instructions. Also, since the method is relatively simple, it is easy to be realized by hardware.

[0088] In some embodiments, that the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined according to a third transmission opportunity, where the third transmission opportunity refers to the last transmission opportunity related to the first of the two TRPs before the second transmission opportunity. Similarly, since such a method does not require additional instructions, it can save the overhead of instructions. Also, when the probability of blocking is relatively low for such a method, that is, when the probability of simultaneously receiving adjacent transmission opportunities related to TRP#1 and transmission opportunities related to TRP#2 is high, a higher combining gain can be achieved by defining the relationship between the RVs of adjacent transmission opportunities.

[0089] In the embodiments of the present invention, in some embodiments, as shown in FIG. 5, the method may further include the following steps.

[0090] 502: The terminal device receives indication information, where the indication information indicates the RV of the transmission opportunity of the uplink data related to the first of the two TRPs, and the indication information is included in DCI signaling or RRC signaling.

[0091] According to the above embodiments, the terminal device can obtain the RV of the transmission opportunity of the PUSCH related to the first of the two TRPs (TRP#1), and based on this, the terminal device can determine the RV of the transmission opportunity related to the second of the two TRPs (TRP#2).

[0092] For example, in the foregoing embodiment, the RV of the transmission opportunity associated with TRP#1 is related to the RV of the transmission opportunity associated with TRP#2. In this case, the terminal device can use the relevance between the two to determine the RV of the transmission opportunity associated with TRP#2 based on the RV of the transmission opportunity associated with TRP#1 according to the received above-mentioned instruction information. Since the meaning of the relevance between the two has already been described, the content is incorporated here and the detailed description thereof is omitted here.

[0093] Hereinafter, the above-mentioned instruction will be described by taking FIG. 6 as an example.

[0094] As shown in FIG. 6, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by DCI signaling (dynamically indicated), in some embodiments, rv id is respectively indicated by the scheduling DCI corresponding to the PUSCH (RV field), and rv s is dynamically indicated by the DCI. Specifically, for example, rv s is indicated by one field of the DCI. In the example of FIG. 6, rv s = 0.

[0095] The following Table 1 shows the RV of the actual duplicate transmission opportunity associated with TRP#1 for the nth one, or it can be said that Table 1 shows the actual duplicate RV associated with TRP#1 for the nth one. The following Table 2 shows the RV of the actual duplicate transmission opportunity associated with TRP#2 for the nth one, or it can be said that Table 2 shows the actual duplicate RV associated with TRP#2 for the nth one. In the example shown in FIG. 6, n = 0, 1, 2..., for example, the 0th actual duplicate associated with TRP#1 is Rep#1, and the 0th actual duplicate associated with TRP#2 is Rep#2.

That is, for the uplink data, the RV of the nth transmission opportunity associated with TRP#1 is the same as the RV of the nth transmission opportunity associated with TRP#2. id As shown in FIG. 6, when the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity (default#1), in some embodiments, rv

[0101] As shown in FIG. 6, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default#2), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field). rv s is determined by the last actual duplicate transmission opportunity (the third transmission opportunity) associated with TRP#1 before the second transmission opportunity.

[0102] For example, in FIG. 6, for the second transmission opportunity with the serial number 0 (i.e., n = 0), before the second transmission opportunity, according to FIG. 6, the RV of the last actual duplicate (actual Rep#1) transmission opportunity (the third transmission opportunity) corresponding to TRP#1 is 0. In this case, the RV of the 0th actual duplicate associated with TRP#2 is the next RV after 0, i.e., 2 (following the order of 0-2-3-1). Thus, rv s = 2 - 0 = 2. For the RVs of other transmission opportunities, rv s can be calculated based on 2. Also, the RV sequence used by the actual duplicate transmission opportunities associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the actual duplicate transmission opportunities associated with TRP#2 is also {0, 2, 3, 1}.

[0103] As shown in FIG. 6, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, rv idis indicated by the scheduling DCI corresponding to the PUSCH (RV field), rv s is set by RRC signaling. In the example of FIG. 6, rv s = 0.

[0104] The RVs of the actual duplicate transmission opportunities associated with the n-th and TRP#1 are shown in Table 4 below. The RVs of the actual duplicate transmission opportunities associated with the n-th and TRP#2 are shown in Table 5 below.

[0107] Hereinafter, the above instructions will be described by taking FIG. 7 as an example.

[0108] As shown in FIG. 7, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by DCI signaling (dynamically indicated), in some embodiments, rv id is respectively indicated by the scheduling DCI corresponding to the PUSCH (RV field), rv sis dynamically indicated by the DCI, specifically, for example, rv s is indicated by one field of the DCI. In the example of FIG. 7, rv s = 0.

[0109] The following Table 6 shows the RV of any one transmission opportunity of all the actual repetitions of the n-th nominal repetition associated with TRP#1. The following Table 7 shows the RV of any one transmission opportunity of all the actual repetitions of the n-th nominal repetition associated with TRP#2. In the example shown in FIG. 7, n = 0, 1, 2..., for example, the 0-th nominal repetition associated with TRP#1 is Nominal Rep#1, and the 0-th nominal repetition associated with TRP#2 is Nominal Rep#2.

[0112] As shown in FIG. 7, when the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity (default #1), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field). That is, the RV of any one transmission opportunity of all the actual repetitions of the nominal repetition associated with TRP #1 in the nth is the same as the RV of any one transmission opportunity of all the actual repetitions of the nominal repetition associated with TRP #2 in the nth.

[0113] The following Table 8 shows the RV of any one transmission opportunity of all the actual repetitions of the nominal repetition associated with TRP #1 or TRP #2 in the nth.

[0115] As shown in FIG. 7, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default #2), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field). rv s is determined by the transmission opportunity of the last actual repetition associated with TRP #1 before the second transmission opportunity.

[0116] For example, in FIG. 7, for the second transmission opportunity with the sequence number 0 (i.e., n = 0), before this second transmission opportunity, according to FIG. 7, for the transmission opportunity (the third transmission opportunity) of the last actual repetition (Rep#1) corresponding to TRP#1, the RV is 0. In this case, the RV of the actual repetition related to TRP#2 at the 0th position is the next RV after 0, that is, 2 (following the order of 0-2-3-1), whereby, rv s = 2 - 0 = 2. For the RVs of other transmission opportunities, rv s may be calculated based on 2. Also, the RV sequence used by the nominal repetition associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the nominal repetition associated with TRP#2 is also {0, 2, 3, 1}.

[0117] As shown in FIG. 7, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field), and rv s is set by RRC signaling. In the example of FIG. 7, rv s = 0.

[0118] The following Table 9 shows the RVs of any one transmission opportunity of all actual repetitions of the nominal repetition associated with TRP#1 at the nth position. The following Table 10 shows the RVs of any one transmission opportunity of all actual repetitions of the nominal repetition associated with TRP#2 at the nth position.

In the example of FIG. 8, rv s =1.

[0123] The following Table 11 shows the RV sequences used by the transmission opportunities of the actual repetitions associated with TRP#1 for the nth. The following Table 12 shows the RV sequences used by the transmission opportunities of the actual repetitions associated with TRP#2 for the nth. Note that in the example shown in FIG. 8, n = 0, 1, 2..., for example, the 0th actual repetition associated with TRP#1 is Actual Rep#1, and the 0th actual repetition associated with TRP#2 is Actual Rep#2.

[0127] As can be seen from FIG. 8, when rv is indicated as 0 by the DCI that schedules the PUSCH, according to Table 11, the RV of the actual duplicate transmission opportunity associated with TRP#1 at the 0th position is 0. Also, in this example, since rv

[0129] As shown in Figure 8, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default#2), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field). rv s is determined by the last actual duplicate transmission machine associated with TRP#1 before the second transmission opportunity.

[0130] For example, in Figure 8, for the second transmission opportunity with the serial number 0 (i.e., n = 0), before the second transmission opportunity, according to Figure 8, the RV of the last actual duplicate (Rep#1) transmission opportunity (the third transmission opportunity) corresponding to TRP#1 is 0. In this case, the RV of the actual duplicate associated with the 0th TRP#2 is the next RV after 0, i.e., 2 (following the order of 0 - 2 - 3 - 1). Thus, rv s = 2 - 0 = 2. For the RVs of other transmission opportunities, rv s can be calculated based on 2. Also, the RV sequence used by the actual duplicate associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the actual duplicate associated with TRP#2 is also {0, 2, 3, 1}.

[0131] As shown in Figure 8, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, rv idis indicated by the scheduling DCI corresponding to PUSCH (RV field), rv s is set by RRC signaling. In the example of FIG. 8, rv s = 3.

[0136] As shown in FIG. 9, when the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity (default#1), in some embodiments, based on the following Table 22, the RV, that is, the RV of the n-th actual duplicate transmission opportunity associated with TRP#1, and the RV of the n-th actual duplicate transmission opportunity associated with TRP#2 can be determined.

[0137] Table 16 below shows the RVs of the actual duplicate transmission opportunities associated with the n-th, TRP#1 or TRP#2. In the example shown in FIG. 9, n = 0, 1, 2..., for example, the actual duplicate associated with the 0-th, TRP#1 is Actual Rep#1, and the actual duplicate associated with the 0-th, TRP#2 is Actual Rep#2.

Table 16

[0139] As shown in FIG. 9, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default#2), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field). rv s is determined by the last actual duplicate transmission opportunity associated with TRP#1 before the second transmission opportunity.

[0140] For example, in FIG. 9, for the second transmission opportunity with a serial number of 0 (i.e., n = 0), before the second transmission opportunity, according to FIG. 9, the RV of the last actual duplicate (Rep#1) transmission opportunity (the third transmission opportunity) corresponding to TRP#1 is 0. In this case, the RV of the actual duplicate associated with the 0-th, TRP#2 is the next RV after 0, i.e., 2 (following the order of 0-2-3-1), whereby rv sIt becomes =2 - 0 = 2. For the RVs of other transmission opportunities, they can be calculated based on rvs = 2. Also, the RV sequence used by the actual duplicate transmission opportunities associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the actual duplicate transmission opportunities associated with TRP#2 is also {0, 2, 3, 1}.

[0141] As shown in FIG. 9, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, the RV can be determined based on Table 17 and Table 18 below. Among them, rv s is set by RRC signaling. In the example of FIG. 9, rv s = 0.

[0142] Table 17 below shows the RVs of the nth actual duplicate transmission opportunities associated with TRP#1. Table 18 below shows the RVs of the nth actual duplicate transmission opportunities associated with TRP#2.

[0145] Hereinafter, taking FIG. 10 as an example, the above instructions will be described.

[0146] As shown in FIG. 10, when the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity (default#1), in some embodiments, the RV can be determined based on Table 19. That is, for uplink data, the RV of the nth actual duplicate transmission opportunity associated with TRP#1 is the same as the RV of the nth actual duplicate transmission opportunity associated with TRP#2.

[0147] The following Table 19 shows the RV sequences used by the actual duplicate transmission opportunities associated with the nth TRP#1 or TRP#2. In the example shown in FIG. 10, n = 0, 1, 2..., for example, the second actual duplicate associated with TRP#1 is Actual Rep#1, and the first actual duplicate associated with TRP#2 is Actual Rep#2. It should be noted that it is necessary to consider the transmission opportunities not used for data transmission (the dotted line part in FIG. 10).

[0148]

Table 19

[0149] As shown in FIG. 10, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default#2), in some embodiments, rv idIt is indicated by the scheduling DCI corresponding to PUSCH (RV field). Among them, RVshift is determined by the last actual repeated transmission opportunity related to TRP#1 before the second transmission opportunity.

[0150] For example, in Figure 10, for the second transmission opportunity with the serial number 0 (i.e., n = 0), before this second transmission opportunity, according to Figure 10, the transmission opportunity (the third transmission opportunity) of the last actual repetition (Rep#1) corresponding to TRP#1 has RV = 0. In this case, the RV of the actual repetition related to TRP#2 at the 0th position is the next RV after 0, that is, 3 (following the order of 0-3-0-3), whereby RVshift = 1 (i.e., starting from 3 as shown in Table 21). For the RVs of other transmission opportunities, they can be derived by referring to Table 21 based on RVshift = 1. Also, the RV sequence used by the transmission opportunities of the actual repetitions associated with TRP#1 is {0, 3, 0, 3}, and the RV sequence used by the transmission opportunities of the actual repetitions associated with TRP#2 is also {0, 3, 0, 3}.

[0151] As shown in Figure 10, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, the RV can be determined based on Tables 20 and 21. RVshift is set by RRC signaling. In the example of Figure 10, RVshift = 1.

[0152] The following Table 20 shows the RVs of the actual repetitions of the nth transmission opportunity associated with TRP#1. The following Table 21 shows the RVs of the actual repetitions of the nth transmission opportunity associated with TRP#2.

[0153]

Table 20

[0154]

Table 21

[0155] Hereinafter, taking FIG. 11 as an example, the above instructions will be described.

[0156] As shown in FIG. 11, the RV sequence used by the transmission opportunities of the actual duplicate associated with TRP#1 is {0, 0, 0, 0}, and the RV sequence used by the transmission opportunities of the actual duplicate associated with TRP#2 is also {0, 0, 0, 0}. That is, the RV of each transmission opportunity of the uplink data is all 0. In the example shown in FIG. 11, n = 0, 1, 2..., for example, the 2nd actual duplicate associated with TRP#1 is Actual Rep#1, and the 1st actual duplicate associated with TRP#2 is Actual Rep#2. It should be noted that it is necessary to consider the transmission opportunities not for data transmission (the dotted line part in FIG. 11).

[0157] In the above embodiments, in some embodiments, among at least one transmission opportunity of the uplink data, the RV sequence used by the transmission opportunity associated with the first TRP among the above two TRPs is the same as the RV sequence used by the transmission opportunity associated with the second TRP among the above two TRPs. Thereby, since multiple TRPs can utilize the same RV sequence, signaling overhead can be saved.

[0158] In an embodiment of the present invention, in some embodiments, the uplink data starts from an actual duplicate transmission opportunity that is related to the first TRP (TRP#1) of the above two TRPs and has a corresponding RV of 0. Thereby, the terminal device only allows the start of PUSCH transmission in a transmission opportunity with relatively high reliability. The advantage of doing so is that when the CG is large, the network device only needs to assume that PUSCH transmission may occur in some PUSCH transmission opportunities. In this way, the number of blind detections (blind detections) on the network device side can be reduced, and the design complexity on the network device side can be reduced.

[0159] Taking FIG. 10 as an example, the PUSCH starts only from some PUSCH transmission opportunities. That is, if the set RV sequence is {0, 3, 0, 3}, the initial transmission of the transmission block of the set grant may start from any transmission opportunity of the actual duplicate related to RV = 0 and TRP#1.

[0160] As shown in FIG. 10, since RV = 0, the PUSCH transmission starts from the 0th or 2nd transmission opportunity of the actual duplicate related to TRP#1.

[0161] Taking FIG. 11 as an example, the PUSCH starts only from some PUSCH transmission opportunities. That is, when the set RV sequence is {0, 0, 0, 0}, the initial transmission of the transmission block of the set grant may start from any transmission opportunity of the actual duplicate related to RV = 0 and TRP#1.

[0162] As shown in FIG. 11, since RV = 0, the PUSCH transmission starts from the 0th, 1st, 2nd, or 3rd transmission opportunity of the actual duplicate related to TRP#1.

[0163] In an embodiment of the present invention, in some embodiments, at least one transmission opportunity of the uplink data being related to two TRPs means At least one transmission opportunity of the uplink data is associated with the above two TRPs respectively in units of at least one nominal duplicate transmission opportunity of the uplink data (mapping); or At least one transmission opportunity of the uplink data is associated with the above two TRPs respectively in units of at least one actual duplicate transmission opportunity of the uplink data (mapping); or At least one transmission opportunity of the uplink data is associated with the above two TRPs respectively in units of at least one slot (mapping). This is what is meant.

[0164] It should be noted that the present invention is not limited to specific implementation manners.

[0165] In an embodiment of the present invention, the TRP is equivalent to at least one of the following concepts, that is, Transmission configuration indication state (TCI state); Spatial relation; Reference signal; Reference signal set; SRS resource set (the resource set includes one or more SRS resources); Spatial domain filter; Power control parameter; and A group of time alignment related parameters That's it.

[0166] It should be noted that for the specific meanings of these concepts, reference can be made to related technologies, and detailed descriptions thereof are omitted here.

[0167] For example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to that at least one transmission opportunity of PUSCH is associated with at least two TCI states, that is, the terminal device transmits the PUSCH based on the parameters corresponding to the above-mentioned at least two TCI states.

[0168] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to that at least one transmission opportunity of PUSCH is associated with at least two spatial relationships.

[0169] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to that at least one transmission opportunity of PUSCH is associated with at least two reference signals. Here, the reference signal may be a pathloss reference signal (pathloss RS), or may be a CSI-RS (Channel State Information Reference Signal), an SSB (Synchronization Signal Block), an SRS (Sounding Reference Signal), etc., but the present invention is not limited thereto.

[0170] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to that at least one transmission opportunity of PUSCH is associated with at least two reference signal sets. The reference signal set is one or more reference signals (RS). Here, the reference signal may be a pathloss reference signal (pathloss RS), or may be a CSI-RS (Channel State Information Reference Signal), an SSB (Synchronization Signal Block), an SRS (Sounding Reference Signal), etc., but the present invention is not limited thereto.

[0171] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two spatial domain filters.

[0172] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two power control parameters.

[0173] Note that the above-mentioned FIG. 5 is for illustratively explaining an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or several operations can be increased or decreased. In addition, those skilled in the art can make appropriate modifications based on the above content, not limited to the description of the above-mentioned FIG. 5.

[0174] According to the method according to the embodiment of the present invention, when blocking occurs, even if only some of the TRPs can work, a relatively high combining gain can be guaranteed compared to the case where the RV is independent of the TRP. The reason is as follows: that is, such a method can be adjusted based on the information of the TRP associated with the RV of the transmission opportunity of the uplink data described above, that is, when the TRPs corresponding to the above-mentioned uplink data transmission opportunities are different, or when a change occurs in the probability that the corresponding TRP is blocked, the RV of each transmission opportunity can be flexibly and optimally determined based on the associated information of the TRP, so that the system performance can be improved.

[0175] <Embodiment of the second aspect> In an embodiment of the present invention, a method for transmitting uplink data is provided, and the description is given from the perspective of the terminal device. The difference from the embodiment of the first aspect is as follows: that is, the method of the embodiment of the present invention is applicable to uplink data (PUSCH) transmitted in the PUSCH repetition type A manner. Here, the description of the same content as in the embodiment of the first aspect is omitted. Further, in the embodiment of the present invention, the scenario of the dynamically scheduled PUSCH shown in FIG. 1 and the scenario of the configured grant PUSCH shown in FIG. 2 are taken as examples for the description.

[0176] FIG. 12 is a diagram showing a method for transmitting uplink data in an embodiment of the present invention. As shown in FIG. 12, the method includes the following steps.

[0177] 1201: The terminal device transmits uplink data in the PUSCH repetition type A manner, at least one transmission opportunity of the uplink data is associated with two TRPs, and the RV of at least one transmission opportunity of the uplink data is determined (derived) based on the two TRPs.

[0178] According to the method of the embodiment of the present invention, when blocking occurs, even if only some of the TRPs can work, it can be guaranteed that a relatively high combining gain can be obtained compared with the case where the RV release is independent of the TRP. The reason is as follows: that is, such a method can make the RV release of the above-mentioned uplink data transmission opportunity be adjusted based on the information of the TRP related thereto. That is, when the TRPs corresponding to the above-mentioned uplink data transmission opportunities are different, or when a change occurs in the probability that the corresponding TRP is blocked, the RV release of each transmission opportunity can be flexibly and optimally determined based on the related information of the TRP, so that the system performance can be improved.

[0179] In some embodiments, that the RV of at least one transmission opportunity of the uplink data is derived by the above two TRPs means that, among at least one transmission opportunity of the uplink data, the RV of the transmission opportunity associated with the first TRP among the above two TRPs is determined according to the time domain order of the transmission opportunities associated with the first TRP, and among at least one transmission opportunity of the uplink data, the RV of the transmission opportunity associated with the second TRP among the above two TRPs is determined according to the time domain order of the transmission opportunities associated with the second TRP. That is, the RV sequence is cyclically mapped based on the transmission opportunities of the PUSCH.

[0180] FIG. 13 is a diagram showing an example of the mapping relationship between a dynamically scheduled PUSCH and an RV sequence. As shown in FIG. 13, the mapping relationship between the PUSCH and the two TRPs is inter-slot TRP mapping, that is, the PUSCH performs cyclic mapping (association) with the two TRPs in units of one transmission opportunity, and the RV sequence (which is {0, 2, 3, 1} in FIG. 13) is cyclically mapped to the transmission opportunities within each slot of the PUSCH. That is, the mapping method of the RV sequence is slot based RV mapping.

[0181] In the example of FIG. 13, the RV sequence used by the transmission opportunities associated with TRP#1 is the same as the RV sequence used by the transmission opportunities associated with TRP#2, and both are {0, 2, 3, 1}. Also, the offset between the RV of the nth transmission opportunity of the PUSCH associated with TRP#1 and the RV of the nth transmission opportunity of the PUSCH associated with TRP#2 is rv s where n is a natural number. Also, the RV is cyclically mapped based on the transmission opportunities associated with each TRP.

[0182] FIG. 14 is a diagram showing an example of the mapping relationship between the configured grant PUSCH and the RV sequence. As shown in FIG. 14, the TRP mapping method of the PUSCH and the mapping method of the RV sequence are the same as those in FIG. 13.

[0183] In the example of FIG. 14, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are 0231. Also, the difference (offset) between the RV of the n-th transmission opportunity of the PUSCH related to TRP#1 and the RV of the n-th transmission opportunity of the PUSCH related to TRP#2 is rv s is. Also, the RV is cyclically mapped based on the transmission opportunities related to each TRP.

[0184] FIG. 15 is a diagram showing another example of the mapping relationship between the configured grant PUSCH and the RV sequence. As shown in FIG. 15, the TRP mapping method of the PUSCH and the mapping method of the RV sequence are the same as those in FIG. 13.

[0185] In the example of FIG. 15, the difference from the example of FIG. 14 is as follows: that is, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are {0, 3, 0, 3}. Also, the difference (cyclic shift) between the RV of the n-th transmission opportunity of the PUSCH related to TRP#1 and the RV of the n-th transmission opportunity of the PUSCH related to TRP#2 is RVshift.

[0186] FIG. 16 is a diagram showing yet another example of the mapping relationship between the configured grant PUSCH and the RV sequence. As shown in FIG. 16, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, and both are {0, 0, 0, 0}.

[0187] In some embodiments, the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data. Among them, the first transmission opportunity refers to the transmission opportunity among the transmission opportunities of the uplink data that is related to the first TRP among the above two TRPs, and the second transmission opportunity refers to the transmission opportunity among the transmission opportunities of the uplink data that is related to the second TRP among the above two TRPs. That is, among the transmission opportunities of the uplink data, the RV of the transmission opportunity related to TRP#1 is associated with the RV of the transmission opportunity related to TRP#2. Thereby, the terminal device can improve the merging gain of the uplink data by using the relationship between the two. The reason is as follows. That is, compared with the case where there is no relevance between the transmission opportunities related to different TRPs, the RV of the transmission opportunity related to TRP#1 is related to the RV of the transmission opportunity related to TRP#2. Then, the transmission opportunity of TRP#1 and the transmission opportunity related to TRP#2 are adjacent in the time domain, and in a scenario where the probability of blocking is relatively low (that is, when the probability of simultaneously receiving the adjacent transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 is high), by optimizing the corresponding RV release, a higher merging gain can be realized.

[0188] In some embodiments, the sequence number related to the first transmission opportunity is the same as the sequence number related to the second transmission opportunity. Here, the sequence number is the sequence number corresponding to the transmission opportunity.

[0189] In some embodiments, that the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling. Thereby, the network device can, according to the actual situation, semi-statically adjust the RV of the transmission opportunity of the PUSCH corresponding to TRP#2 by RRC signaling, so as to improve the merging gain of the corresponding uplink data signal, and thus improve the system performance.

[0190] In the above embodiments, the difference is an offset, for example, rv shown in FIGS. 13 and 14 s may be, or may refer to a shift, for example, RV shift shown in FIG. 15.

[0191] In some embodiments, that the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by DCI signaling. Thereby, the network device can flexibly indicate the corresponding RV based on each PUSCH transmission.

[0192] The above embodiments are applicable to a dynamically scheduled PUSCH, for example, the scenario shown in FIG. 13.

[0193] For example, the above difference is indicated by the corresponding unit in the TDRA field of the above DCI signaling. Thereby, there is no need to increase an additional DCI field, the size of the DCI can be reduced, and the reliability of the control channel can be improved.

[0194] Also, for example, the above difference is indicated by one field in the DCI signaling. Thereby, the indication is simple, the implementation difficulty and cost are relatively low, and the impact on standardization is relatively small.

[0195] In some embodiments, that the RV of the first transmission opportunity of the uplink data is related to the RV of the second transmission opportunity of the uplink data means that the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity. Such a method does not require additional indication, can save the indication overhead, and the method is relatively simple and is easy to be implemented by hardware.

[0196] In some embodiments, the RV of the first transmission opportunity of the uplink data being related to the RV of the second transmission opportunity of the uplink data means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined by a third transmission opportunity, where the third transmission opportunity refers to the last transmission opportunity related to the first of the two TRPs mentioned above before the second transmission opportunity. Similarly, such a method does not require additional instructions, can save the overhead of instructions, and when the probability of blocking is relatively small (i.e., when the probability of simultaneously receiving adjacent transmission opportunities related to TRP#1 and transmission opportunities related to TRP#2 is large), by defining the relationship between the RV releases of adjacent transmission opportunities, a higher combining gain can be achieved.

[0197] In the embodiments of the present invention, in some embodiments, as shown in FIG. 12, the method may further include the following steps.

[0198] 1202: The terminal device receives the indication information, where the indication information indicates the RV of the transmission opportunity of the uplink data related to the first of the two TRPs, and the indication information is included in DCI signaling or RRC signaling.

[0199] According to the above embodiments, the terminal device can obtain the RV of the transmission opportunity of the PUSCH related to the first of the two TRPs (TRP#1), and thereby the terminal device can determine the RV of the transmission opportunity related to the second of the two TRPs (TRP#2) based on this.

[0200] For example, in the previous embodiment, since the RV of the transmission opportunity related to TRP#1 is associated with the RV of the transmission opportunity related to TRP#2, the terminal device can use the relevance between the two to determine the RV of the transmission opportunity related to TRP#2 based on the RV of the transmission opportunity related to TRP#1 according to the above-mentioned received instruction information. Note that since the meaning of the association (relevance) between the two has already been explained, the content is incorporated here and the detailed explanation thereof is omitted here.

[0201] Hereinafter, the above-mentioned instruction will be described by taking FIG. 13 as an example.

[0202] As shown in FIG. 13, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by DCI signaling (dynamically indicated), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field), and rv s is dynamically indicated by DCI. Specifically, for example, rv s is indicated by one field of the DCI. In the example of FIG. 13, rv s = 1.

[0203] The following Table 22 shows the RV sequence used by the nth transmission opportunity associated with TRP#1, or it can also be said that Table 22 shows the RV of the nth transmission opportunity associated with TRP#1. The following Table 23 shows the RV sequence used by the nth transmission opportunity associated with TRP#2, or it can also be said that Table 23 shows the RV of the nth transmission opportunity associated with TRP#2. Note that in the example shown in FIG. 13, n = 0, 1, 2..., for example, the 0th transmission opportunity associated with TRP#1 is Rep#1, and the 0th transmission opportunity associated with TRP#2 is Rep#2.

[0204]

Table 22

[0205]

Table 23

[0206] is indicated by the scheduling DCI corresponding to the PUSCH (RV field). That is, for the uplink data, the RV of the nth transmission opportunity associated with TRP#1 is the same as the RV of the nth transmission opportunity associated with TRP#2. id The following Table 24 shows the RVs used by the nth transmission opportunities associated with TRP#1 or TRP#2.

[0207]

Table 24

[0208] As can be seen from FIG. 13, when rv is instructed by the DCI that schedules the PUSCH id ​When instructed as =0, according to Table 24, the RV used by the 0th transmission opportunity associated with TRP#1 is the same as the RV used by the 0th transmission opportunity associated with TRP#2, and both are 0. Also, the RV sequence used by the transmission opportunities associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the transmission opportunities associated with TRP#2 is also {0, 2, 3, 1}.

[0209] As shown in Figure 13, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default#2), in some embodiments, rv id is indicated by the scheduling DCI corresponding to the PUSCH (RV field). rv s is determined by the transmission opportunity associated with TRP#1 before the second transmission opportunity.

[0210] For example, in Figure 13, for the second transmission opportunity with the serial number 0 (i.e., n = 0), before the second transmission opportunity, according to Figure 13, the RV of the transmission opportunity corresponding to TRP#1 (the third transmission opportunity) is 0. In this case, the RV of the 0th transmission opportunity associated with TRP#2 is the next RV after 0, i.e., 2 (following the order of 0-2-3-1). Thus, rv s = 2 - 0 = 2. For the RVs of other transmission opportunities, rv s can be calculated based on 2. Also, the RV sequence used by the transmission opportunities associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the transmission opportunities associated with TRP#2 is also {0, 2, 3, 1}.

[0211] The following Table 25 shows the RVs used by the nth transmission opportunity associated with TRP#1. The following Table 26 shows the RVs used by the nth transmission opportunity associated with TRP#2.

[0212]

Table 25

[0213]

Table 26

[0214] is indicated by the scheduling DCI corresponding to the PUSCH (RV field), and rv id is set by RRC signaling. In the example of FIG. 13, rv s = 2. s = 2.

[0215] The following Table 27 shows the RV used by the nth transmission opportunity associated with TRP#1. The following Table 28 shows the RV used by the nth transmission opportunity associated with TRP#2.

[0217]

Table 28

[0218] Hereinafter, taking FIG. 14 as an example, the above instructions will be described.

[0219] As shown in FIG. 14, when the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity (default#1), in some embodiments, the RV can be determined based on Table 29 below. That is, for the uplink data, the RV of the nth transmission opportunity associated with TRP#1 is the same as the RV of the nth transmission opportunity associated with TRP#2.

[0220] Table 29 below shows the RV used by the nth transmission opportunity associated with TRP#1 or TRP#2.

[0221]

Table 29

[0222] As shown in FIG. 14, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default #2), in some embodiments, the RV can be determined based on the following Table 40 and Table 41. Among them, rv s is determined by the transmission opportunity associated with TRP#1 before the second transmission opportunity.

[0223] For example, in FIG. 14, for the second transmission opportunity with a sequence number of 0 (i.e., n = 0), before this second transmission opportunity, according to FIG. 14, the RV of the transmission opportunity corresponding to TRP#1 (the third transmission opportunity) is 0. In this case, the RV of the 0th transmission opportunity associated with TRP#2 is the next RV after 0, that is, 2 (following the order of 0-2-3-1). Thus, rv s = 2 - 0 = 2. For the RVs of other transmission opportunities, they can be calculated based on rvs = 2. Also, the RV sequence used by the transmission opportunities associated with TRP#1 is {0, 2, 3, 1}, and the RV sequence used by the transmission opportunities associated with TRP#2 is also {0, 2, 3, 1}.

[0224] The following Table 30 shows the RVs used by the nth transmission opportunity associated with TRP#1. The following Table 31 shows the RVs used by the nth transmission opportunity associated with TRP#2.

Table 31

[0227] As shown in FIG. 14, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, the RV can be determined based on the following Table 32 and Table 33. Among them, rv s is set by RRC signaling. In the example of FIG. 14, rv s = 2.

[0228] The following Table 32 shows the RV used by the nth transmission opportunity associated with TRP#1, and the following Table 33 shows the RV used by the nth transmission opportunity associated with TRP#2.

Table 33

[0231] Hereinafter, the above instructions will be described taking FIG. 15 as an example.

[0232] As shown in FIG. 15, when the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity (default #1), in some embodiments, the RV can be determined based on Table 34. That is, for the uplink data, the RV of the nth transmission opportunity associated with TRP#1 is the same as the RV of the nth transmission opportunity associated with TRP#2.

[0233] The following Table 34 shows the RVs used by the nth transmission opportunity associated with TRP#1 or TRP#2.

[0234]

Table 34

[0235] As shown in FIG. 15, when determining the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity based on the third transmission opportunity (default #2), in some embodiments, the RV can be determined based on Table 35 and Table 36 below. Among them, RVshift is determined by the transmission opportunity associated with TRP#1 before the second transmission opportunity.

[0236] For example, in Fig. 15, for the second transmission opportunity with the serial number 0 (i.e., n = 0), before this second transmission opportunity, according to Fig. 15, for the transmission opportunity corresponding to TRP#1 (the third transmission opportunity), the RV is 0. In this case, for the 0th transmission opportunity related to TRP#2, the RV is the next RV after 0, i.e., 3 (following the order of 0-3-0-3), and thus, RVshift = 1. For the RVs of other transmission opportunities, they can be calculated based on RVshift = 1. Also, the RV sequence used by the transmission opportunities associated with TRP#1 is {0, 3, 0, 3}, and the RV sequence used by the transmission opportunities associated with TRP#2 is also {0, 3, 0, 3}.

[0237] The following Table 35 shows the RVs used by the nth transmission opportunity associated with TRP#1. The following Table 36 shows the RVs used by the nth transmission opportunity associated with TRP#2.

[0239]

Table 36

[0240] As shown in FIG. 15, when the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is indicated by RRC signaling (RRC configured), in some embodiments, the RV can be determined based on Table 37 and Table 38 below. RVshift is set by RRC signaling. In the example of FIG. 15, RVshift = 1.

[0241] Table 37 below shows the RV used by the nth transmission opportunity associated with TRP#1. Table 38 below shows the RV used by the nth transmission opportunity associated with TRP#2.

[0242]

Table 37

[0243]

Table 38

[0244] Hereinafter, the above instruction will be described taking FIG. 16 as an example.

[0245] As shown in Fig. 16, the RV sequence used by the transmission opportunity associated with TRP#1 is {0, 0, 0, 0}, and the RV sequence used by the transmission opportunity associated with TRP#2 is also {0, 0, 0, 0}. That is, the RV of each transmission opportunity of the uplink data is all 0. In the example shown in Fig. 16, n = 0, 1, 2..., for example, the second transmission opportunity associated with TRP#1 is Rep#1, and the first transmission opportunity associated with TRP#2 is Rep#2.

[0246] In the above embodiments, in some embodiments, among at least one transmission opportunity of the uplink data, the RV sequence used by the transmission opportunity associated with the first TRP among the above two TRPs is the same as the RV sequence used by the transmission opportunity associated with the second TRP among the above two TRPs among at least one transmission opportunity of the above uplink data. Thereby, since a plurality of TRPs can share the same RV sequence, the signaling overhead can be saved.

[0247] In the embodiments of the present invention, in some embodiments, the uplink data is associated with the first TRP (TRP#1) among the above two TRPs and starts from a transmission opportunity where the corresponding RV is 0. Thereby, the terminal device only allows the start of PUSCH transmission in a transmission opportunity with relatively high reliability. The advantage of doing so is that when the CG is large, the network device needs to assume that PUSCH transmission may occur in only some of the PUSCH transmission opportunities. In this way, the number of blind detection times on the network device side can be reduced, and the design complexity on the network device side can be reduced.

[0248] Taking Fig. 15 as an example, PUSCH starts from only some of the PUSCH transmission opportunities. That is, when the set RV sequence is {0, 3, 0, 3}, the initial transmission of the transmission block of the set grant may start from any transmission opportunity associated with RV = 0 and TRP#1.

[0249] As shown in FIG. 15, since RV = 0, the transmission of PUSCH may start from the 0th transmission occasion (Rep#1).

[0250] Taking FIG. 16 as an example, PUSCH starts only from several PUSCH transmission occasions. That is, when the set RV sequence is {0, 0, 0, 0}, the initial transmission of the transmission block of the set grant may start from any transmission occasion of RV = 0 and the actual repetition related to TRP#1.

[0251] As shown in FIG. 16, since RV = 0, the transmission of PUSCH may start from the 0th or 2nd transmission occasion (Rep#1 or Rep#3).

[0252] In the embodiments of the present invention, in some embodiments, at least one transmission occasion of the uplink data being related to two TRPs means that at least one transmission occasion of the uplink data is related to the above two TRPs respectively in units of at least one slot (mapping); or at least one transmission occasion of the uplink data is related to the above two TRPs respectively in units of at least one time domain part within one slot (mapping). This is what it refers to.

[0253] It should be noted that the present invention is not limited to specific implementation manners.

[0254] In the embodiments of the present invention, the TRP is equivalent to at least one of the following concepts, that is, Transmission configuration indication state (TCI state); Spatial relation; Reference signal; Reference signal set; SRS resource set (the resource set includes one or more SRS resources); Spatial domain filter; Power control parameter; and A group of time alignment related parameters are provided.

[0255] For the specific meanings of these concepts, reference can be made to the related art, and detailed descriptions thereof are omitted here.

[0256] For example, the fact that at least one transmission opportunity of PUSCH is related to at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is related to at least two TCI states, that is, the terminal device transmits the PUSCH based on the parameters corresponding to the above-mentioned at least two TCI states.

[0257] Also, for example, the fact that at least one transmission opportunity of PUSCH is related to at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is related to at least two spatial relationships.

[0258] Also, for example, the fact that at least one transmission opportunity of PUSCH is related to at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is related to at least two reference signals. Here, the reference signal may be a pathloss reference signal, or may be a CSI-RS (Channel State Information Reference Signal), an SSB (Synchronization Signal Block), an SRS (Sounding Reference Signal), etc., but the present invention is not limited thereto.

[0259] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two sets of reference signals. A set of reference signals is one or more reference signals (RS). Here, the reference signal may be a pathloss reference signal, or may be a CSI-RS (Channel State Information Reference Signal), an SSB (Synchronization Signal Block), an SRS (Sounding Reference Signal), etc., but the present invention is not limited thereto.

[0260] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two spatial domain filters.

[0261] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two power control parameters.

[0262] Note that the above-mentioned FIG. 12 is for exemplarily explaining an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or several operations can be increased or decreased. Also, those skilled in the art are not limited to the description of the above-mentioned FIG. 12, and can make appropriate modifications based on the above-mentioned content.

[0263] According to the method of the embodiment of the present invention, when blocking occurs, even if only some of the TRPs can work, a relatively high merging gain can be guaranteed compared to the case where the RV release is independent of the TRPs. The reason is as follows: such a method can make the RV release of the uplink data transmission opportunity described above be adjusted based on the information of the relevant TRP, that is, when the TRPs corresponding to the above-mentioned uplink data transmission opportunities are different, or when a change occurs in the probability that the corresponding TRP is blocked, the RV release of each transmission opportunity can be determined flexibly and optimally based on the relevant information of the TRP, so that the system performance can be improved.

[0264] <Embodiment of the third aspect> In the embodiment of the present invention, a method for transmitting uplink data is provided and described from the perspective of the terminal device.

[0265] FIG. 17 is a diagram showing a method for transmitting uplink data in an embodiment of the present invention. As shown in FIG. 17, the method includes the following steps.

[0266] 1701: The terminal device transmits uplink data, and at least one transmission opportunity of the uplink data is related to two TRPs. Among them, the terminal device performs frequency hopping for the transmission of the uplink data based on the transmission opportunity related to one of the two TRPs among at least one transmission opportunity of the uplink data.

[0267] According to the method according to an embodiment of the present invention, when blocking occurs, even if only some of the TRPs can work, the frequency diversity gain can be better utilized than when the frequency hopping of the uplink data is independent of the TRP. The reason is as follows. That is, such a method can be made to be adjusted based on the information of the TRP related to the frequency hopping pattern of the transmission opportunity of the above-mentioned uplink data. That is, when the TRP corresponding to the above-mentioned uplink data transmission opportunity is different, or when a change occurs in the probability that the corresponding TRP is blocked, the frequency hopping pattern of each transmission opportunity can be flexibly and optimally determined based on the related information of the TRP. Therefore, the frequency domain diversity gain can be increased and the system performance can be improved.

[0268] In some embodiments, among at least one transmission opportunity of the uplink data, the transmission opportunity related to one of the above two TRPs means For the uplink data transmitted in the PUSCH repetition type B manner, among at least one transmission opportunity of the uplink data, the nominal repetition transmission opportunity related to one of the above two TRPs; or For the uplink data transmitted in the PUSCH repetition type B manner, among at least one transmission opportunity of the uplink data, the actual repetition transmission opportunity related to one of the above two TRPs; or For the uplink data transmitted in the PUSCH repetition type A manner, among at least one transmission opportunity of the uplink data in at least one slot, the transmission opportunity related to one of the above two TRPs refers to.

[0269] In some embodiments, performing frequency hopping means performing frequency hopping based on the nominal repetition of uplink data. That is, for the uplink data transmitted in the PUSCH repetition type B manner, frequency hopping is performed based on the nominal repetition of the uplink data or the transmission opportunity of the nominal repetition.

[0270] In some embodiments, performing frequency hopping means performing frequency hopping based on the actual repetition of uplink data. That is, for the uplink data transmitted in the PUSCH repetition type B manner, frequency hopping is performed based on the actual repetition of the uplink data or the transmission opportunity of the actual repetition.

[0271] In some embodiments, performing frequency hopping means performing frequency hopping based on the slot where the uplink data is located.

[0311] According to the method according to the above - mentioned embodiment, the network device can improve the system performance by semi - statically adjusting the frequency hopping pattern corresponding to the TRP associated with the uplink data by RRC signaling based on the channel situation.

[0312] In some embodiments, the above-mentioned indication information indicates the frequency hopping pattern of the uplink data associated with each of the above two TRPs. That is, the frequency hopping pattern is indicated according to each TRP. The advantage of this method is that the network device can semi-statically adjust the frequency hopping pattern corresponding to each TRP by means of RRC signaling based on the channel conditions of each TRP, thereby improving the system performance.

[0313] In some embodiments, the above-mentioned indication information indicates the frequency hopping pattern of the uplink data associated with the first TRP among the above two TRPs, and the frequency hopping pattern of the uplink data associated with the other TRP among the above two TRPs is the same as the frequency hopping pattern of the uplink data associated with the first TRP. That is, the frequency hopping pattern of the other TRP (TRP#2) is the same as the frequency hopping pattern of TRP#1 by default. The merit of this method is that it can reduce the signaling of the indication and save overhead.

[0314] In an embodiment of the present invention, the frequency hopping pattern includes at least one of the following, that is, whether to perform frequency hopping; the number of hops; the starting frequency region position of the frequency hopping; and the frequency offset of the frequency hopping is.

Thereby, by using the same frequency hopping pattern for multiple TRPs, the signaling overhead can be saved.

[0316] In embodiments of the present invention, in some embodiments, that at least one transmission opportunity of uplink data is associated with two TRPs means that at least one transmission opportunity of the uplink data is respectively associated with the above-mentioned two TRPs in units of at least one nominal duplicate transmission opportunity of the uplink data; or at least one transmission opportunity of the uplink data is respectively associated with the above-mentioned two TRPs in units of at least one actual duplicate transmission opportunity of the uplink data; or at least one transmission opportunity of the uplink data is respectively associated with the two TRPs in units of at least one slot This is what is meant.

[0317] Note that the present invention does not limit specific implementation manners.

[0319] For the specific meanings of these concepts, reference can be made to the related art, and detailed descriptions thereof are omitted here.

[0320] For example, the fact that at least one transmission opportunity of PUSCH is related to at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is related to at least two TCI states. That is, the terminal device transmits the PUSCH based on the parameters corresponding to the above at least two TCI states.

[0321] Also, for example, the fact that at least one transmission opportunity of PUSCH is correlated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is related to at least two spatial relationships.

[0322] Also, for example, the fact that at least one transmission opportunity of PUSCH is related to at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is related to at least two reference signals. Here, the reference signal may be a pathloss reference signal (pathloss RS), or may be a CSI-RS (Channel State Information Reference Signal), an SSB (Synchronization Signal Block), an SRS (Sounding Reference Signal), etc., but the present invention is not limited thereto.

[0323] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two sets of reference signals. The set of reference signals is one or more reference signals (RS). Here, the reference signal may be a pathloss reference signal, or may be a CSI-RS (Channel State Information Reference Signal), an SSB (Synchronization Signal Block), an SRS (Sounding Reference Signal), etc., but the present invention is not limited thereto.

[0324] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two spatial domain filters.

[0325] Also, for example, the fact that at least one transmission opportunity of PUSCH is associated with at least two TRPs is equivalent to the fact that at least one transmission opportunity of PUSCH is associated with at least two power control parameters.

[0326] Note that the above-mentioned FIG. 17 is for illustratively explaining an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation (step) can be appropriately adjusted, or several operations can be increased or decreased. Also, those skilled in the art are not limited to the description of the above-mentioned FIG. 17, and appropriate changes can be made based on the above content.

[0327] According to the method in the embodiments of the present invention, when blocking occurs, even if only some of the TRPs can work, the frequency domain diversity gain can be better utilized compared to the case where the frequency hopping of the uplink data is independent of the TRP. The reason is as follows: such a method can be adjusted based on the information of the TRP related to the frequency hopping pattern of the transmission opportunity of the above-mentioned uplink data, that is, when the TRPs corresponding to the above-mentioned uplink data transmission opportunities are different, or when a change occurs in the probability that the corresponding TRP is blocked, the frequency hopping pattern of each transmission opportunity can be determined flexibly and optimally based on the related information of the TRP, so that the frequency domain diversity gain can be increased and the system performance can be improved.
