Description

Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] To simultaneously meet the high reliability and low latency requirements of URLLC (Ultra Reliable Low Latency Communications) services, NR Rel-16 (New Radio Release 16) introduced a corresponding uplink data transmission mechanism. This mechanism supports more flexible uplink data transmission, thereby ensuring that uplink data is sent in a low-latency manner.

[0003] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0004] The inventors found that NR (New Radio) supports a carrier frequency of up to 52.6 GHz. When the carrier frequency is high, due to the poor diffraction ability of high-frequency signals, it is easily blocked by obstacles (blockage). When the transmission path is blocked, the quality of the corresponding transmission channel is severely degraded. This in turn causes a decrease in the reliability of the transmission signal and / or an increase in the transmission delay. This is very unfavorable for URLLC services. In particular, when the signal obstruction is severe to a certain extent, the ongoing URLLC service may be forced to be interrupted or fail. This is because when the existing uplink scheduling mechanism is applied, the terminal device takes at least tens of milliseconds to restore the communication link, and the communication delay requirement of URLLC is generally much less than tens of milliseconds. After the link fails, the URLLC service packet in transmission fails due to timeout before the communication link can reply.

[0005] To reduce the impact of high-frequency transmission channel instability on uplink data transmission, one feasible approach is to transmit uplink data using spatial diversity. That is, on the UE side, the same data can reach the base station via different spatial paths, or different TRPs (transmission and reception points). This way, if one path is blocked, the other paths can continue to operate, ensuring high reliability of uplink data and effectively reducing the impact of channel instability on transmission latency.

[0006] On the other hand, in order to improve combining gain, data transmission usually corresponds to a specific RV (redundancy version). However, when data is transmitted via multiple TRPs, there is no method to indicate the relationship between the corresponding data transmission and the redundancy version, especially the relationship between data transmission in PUSCH repetition type A or PUSCH repetition type B mode and the redundancy version.

[0007] On the other hand, for uplink data transmission, frequency hopping during transmission can effectively utilize frequency domain diversity gain and improve system performance. However, there is currently no method to implement uplink data frequency hopping in multiple TRP scenarios, especially in scenarios where uplink data is sent to different TRPs using PUSCH repetition type A or PUSCH repetition type B.

[0008] In order to solve at least one of the above problems or other similar problems, the embodiments of the present application provide a method, device and system for sending uplink data, so that when uplink data is sent in multiple TRPs, it is sent according to the corresponding RV, thereby enhancing the reliability of uplink data transmission; or, it is sent according to the corresponding frequency hopping mode, so that the uplink data transmission can fully utilize the frequency domain diversity gain and correspondingly improve the reliability.

[0086] In order to make the embodiments of the present application clear and easy to understand, some concepts and definitions involved in the embodiments of the present application are explained below.

[0087] The following describes PUSCH repetition Type A.

[0088] In an embodiment of the present application, PUSCH repetition Type A is a time slot-based uplink data transmission method. A PUSCH (Physical Uplink Shared Channel) sent in PUSCH repetition Type A mode may correspond to one or more repetitions or transmission occasions, denoted as repetition#1, repetition#2,…, repetition#m, where m=1, 2, 3…, K. K is the number of repetitions of the PUSCH. If K>1, there is a repetition in each of K consecutive time slots, and these repetitions have the same time domain / symbol allocation. In addition, these repetitions correspond to the same TB (Transmission Block). Specifically, the PUSCH can be indicated by the following parameters:

[0089] The starting time slot of the PUSCH (denoted as Ks);

[0090] The time domain starting symbol of the PUSCH (denoted as S);

[0091] The time domain length of each repetition (denoted as L); the unit of this length is symbol; and

[0092] Number of repetitions (K): The above-mentioned number of repetitions is, for example, 1, 2, 4, 7, and 16, and may also be 2, 4, or 8. This application is not limited thereto, and the number of repetitions may also be other positive integers.

[0093] It should be noted that the above-mentioned S and L can be indicated separately or jointly through a start and length indicator (SLIV).

[0094] Figure 1 is a schematic diagram of an example of dynamically scheduled PUSCH, such as Figure 1 As shown, when the UE receives a PUSCH transmission indication (for example, PDCCH), it transmits the corresponding PUSCH. The specific parameters are:

[0095] Ks=k; k can be 0, 1, 2, ...

[0096] S=0;

[0097] L = 10;

[0098] K=2.

[0099] exist Figure 1 In the example, the PUSCH time domain resource mapping type (PUSCH mapping type A) is used. The DM-RS (Demodulation Reference Signal) starts at the third symbol of each slot and is configured with a corresponding Phase-Tracking Reference Signal (PT-RS). Since K = 2, the first repetition or first transmission opportunity of the PUSCH is in slot n+k; the second repetition or second transmission opportunity of the PUSCH is in slot n+k+1.

[0100] Figure 2 This is a schematic diagram of an example of configuring a PUSCH grant. Figure 2 As shown, the UE determines that it can start sending PUSCH in slot n+k (that is, there is a PUSCH transmission opportunity starting from slot n+k) based on the CG configuration corresponding to the PUSCH and / or the indication of the activation DCI related to the PUSCH. The corresponding other parameters are:

[0101] S=0;

[0102] L = 10;

[0103] K = 2;

[0104] exist Figure 2 In the example, the PUSCH time domain resource mapping type (PUSCH mapping type A) is used for the PUSCH. The DM-RS starts at the third symbol of each slot and is configured with a corresponding PT-RS. Since K = 2, the first repetition or first transmission opportunity of the PUSCH is in slot n+k; the second repetition or second transmission opportunity of the PUSCH is in slot n+k+1.

[0105] The following describes PUSCH repetition Type B.

[0106] In the embodiment of the present application, PUSCH repetition Type B is a low-latency uplink data transmission method. A PUSCH sent in PUSCH repetition Type B mode can correspond to one or more nominal repetitions or one or more nominal repetition transmission opportunities, denoted as nominal repetition #1, nominal repetition #2, ..., nominal repetition #n, where n = 1, 2, 3 ..., N. Among them, N is the nominal number of repetitions of the PUSCH. Specifically, the PUSCH can be indicated by the following parameters:

[0107] The starting time slot of the PUSCH (denoted as Ks);

[0108] The time domain starting symbol of the PUSCH (denoted as S);

[0109] For PUSCH nominal repetition#n, the time domain start point, time domain end point and time domain length; the time slot corresponding to the time domain start point is The symbol corresponding to the starting point of the time domain is The time slot corresponding to the end point of the time domain is The symbol corresponding to the time domain end point is The unit of time domain length (denoted as L) is symbol; in the above formula, Refers to the symbol corresponding to a time slot;

[0110] Nominal number of repetitions (N); the above-mentioned number of repetitions is, for example, 1, 2, 4, 7, 12, 16, but this application is not limited thereto, and the number of repetitions may also be other positive integers.

[0111] After the UE determines the time domain resources corresponding to the nominal repetition based on the above parameters, it needs to further determine the corresponding actual repetition based on the slot boundary and invalid symbol(s). The determination method is: within a slot, if the number of potentially valid symbols corresponding to a nominal repetition excluding invalid symbols is greater than zero, then the nominal repetition consists of one or more actual repetitions. Each actual repetition consists of all consecutive potentially valid symbols.

[0112] It should be noted that the invalid symbol includes a symbol indicated by higher-layer signaling as downlink. Here, the higher-layer signaling can be a cell-specific uplink / downlink TDD (Time Division Duplexing) configuration, for example, tdd-UL-DL-ConfigurationCommon; the higher-layer signaling can also be a UE-specific uplink / downlink TDD configuration, for example, tdd-UL-DL-ConfigurationDedicated.

[0113] Alternatively, the invalid symbol may also include a symbol corresponding to an invalid symbol pattern indicated by higher-layer signaling. For a type 2 configured grant or dynamically scheduled, whether the invalid symbol pattern is valid can be determined based on the invalid symbol pattern indicator field of the DCI. For example, when the field is set to 1, the corresponding invalid symbol pattern is considered to be valid; when the field is set to 0, the corresponding invalid symbol pattern is considered to be invalid.

[0114] In addition, when L is not equal to 1 and the length of an actual repetition is 1 symbol, the actual repetition will be ignored (omitted) or not sent. When an actual repetition conflicts with the slot format (time slot format), for example, a flexible symbol (flexible symbol) is interpreted / indicated as a DL symbol according to the DCI instruction, the actual repetition will be ignored (omitted) or not sent.

[0115] Figure 3 is a schematic diagram of an example of a dynamically scheduled PUSCH, such as Figure 3 As shown, when the UE receives a PUSCH transmission indication (eg, PDCCH), it sends the PUSCH to the UE within at least T proc,2 Then, the corresponding PUSCH is sent. proc,2 Refers to the PUSCH preparation procedure time (UE PUSCH preparation procedure time); in addition, the other parameters are:

[0116] Ks=k; k can be 0, 1, 2, ...

[0117] S=2;

[0118] L = 5;

[0119] N=5.

[0120] In this example, the slot format of each symbol is configured by high-level signaling, such as Figure 3 As shown in the figure, D represents downlink symbols, U represents uplink symbols, and F represents flexible symbols. In addition, the PUSCH time domain resource mapping mode (PUSCH mapping type) is PUSCH mapping type B, the DM-RS starts at the first symbol of each actual repetition, and is configured with the PT-RS.

[0121] In this example, the PUSCH corresponds to five nominal repetitions and six actual repetitions. Alternatively, the PUSCH corresponds to five nominal repetition transmission opportunities, or six actual repetition transmission opportunities. This is because nominal repetition #3 crosses a slot boundary, and the first symbol of slot n+k+1 is configured as a DL symbol, or an invalid symbol. According to the above rules, this symbol is not counted in the actual repetition. Therefore, nominal repetition #3 is split into two parts (actual repetition #3 and actual repetition #4), each occupying two consecutive symbols.

[0122] Figure 4 This is a schematic diagram of an example of configuring a PUSCH grant. Figure 4 As shown, the UE determines that it can start sending PUSCH in slot n+k (that is, there is a PUSCH transmission opportunity starting from slot n+k) based on the CG configuration corresponding to the PUSCH and / or the indication of the activation DCI related to the PUSCH. The corresponding other parameters are:

[0123] S=2;

[0124] L = 5;

[0125] N=5.

[0126] In this example, the slot format of each symbol is configured by high-level signaling, such as Figure 4 As shown in Figure 1, D represents a downlink symbol, U represents an uplink symbol, and F represents a flexible symbol. In addition, the DM-RS starts at the first symbol of each actual repetition and is configured with a PT-RS.

[0127] In this example, the PUSCH transmissions correspond to five nominal repetitions and six actual repetitions. Alternatively, the PUSCH transmissions correspond to five nominal repetition transmission opportunities, or six actual repetition transmission opportunities. This is because nominal repetition #3 crosses a slot boundary, and the first symbol of slot n+k+1 is configured as a DL symbol, or an invalid symbol. According to the above rules, this symbol is not counted in the actual repetition. Therefore, nominal repetition #3 is split into two parts (actual repetition #3 and actual repetition #4), each occupying two consecutive symbols.

[0128] This application provides multiple TRP transmission solutions for two different uplink data transmission modes (PUSCH repetition Type A and PUSCH repetition Type B).

[0129] Various embodiments of the present application are described below with reference to the accompanying drawings. These embodiments are merely exemplary and are not intended to limit the present application.

[0130] Embodiments of the first aspect

[0131] The embodiment of the present application provides a method for sending uplink data, which is described from the perspective of a terminal device. The method of the embodiment of the application is applicable to uplink data (PUSCH) sent in the manner of PUSCH repetition type B, and Figure 3 The scenario of dynamically scheduled PUSCH and Figure 4 The scenario of configured grant PUSCH is taken as an example for explanation.

[0132] Figure 5 This is a schematic diagram of a method for sending uplink data according to an embodiment of the present application. Figure 5 , the method comprising:

[0133] 501: The terminal device sends uplink data in PUSCH repetition type B mode, at least one transmission opportunity of the uplink data is related to two TRPs, and an RV of the at least one transmission opportunity of the uplink data is derived based on the two TRPs.

[0134] In the embodiments of the present application, transmission opportunities may be understood as time-frequency resources, or as repetitions, and these concepts may be interchangeable.

[0135] In the embodiment of the present application, the transmission opportunity is equivalent to the actual repetition, and is also equivalent to the transmission opportunity of the actual repetition; in addition, the transmission opportunity of the nominal repetition is equivalent to the nominal repetition, and is also equivalent to the transmission opportunity of the actual repetition corresponding to the nominal repetition.

[0136] According to the above method of the embodiment of the present application, it can be ensured that in the event of occlusion, even if only a part of the TRP can work, a higher combining gain can be achieved compared to the case where the RV is unrelated to the TRP. This is because this method allows the RV of the transmission opportunity of the above-mentioned uplink data to be adjusted according to the information of the relevant TRP. That is to say, when the TRP corresponding to the transmission opportunity of the above-mentioned uplink data is different, or when the probability of the corresponding TRP being blocked changes, the RV of each transmission opportunity can be flexibly and optimally determined based on the relevant information of the TRP, thereby improving system performance.

[0137] In some embodiments, the RV of at least one transmission opportunity of uplink data is derived based on the two TRPs, which means that:

[0138] The RV of the actual repetition transmission opportunity associated with the first TRP of the two TRPs in at least one transmission opportunity for uplink data is determined by the time domain order of the actual repetition; and the RV of the actual repetition transmission opportunity associated with the second TRP of the two TRPs in at least one transmission opportunity for uplink data is determined by the time domain order of the actual repetition. In other words, the RV sequence is cyclically mapped to the actual repetition transmission opportunities of the PUSCH.

[0139] In some embodiments, the RV of at least one transmission opportunity of uplink data is derived based on the two TRPs, which means that:

[0140] The RV of a transmission opportunity of a nominal repetition associated with the first of the two TRPs in at least one transmission opportunity for uplink data is determined by the time domain order of the nominal repetition; and the RV of a transmission opportunity of a nominal repetition associated with the second of the two TRPs in at least one transmission opportunity for uplink data is determined by the time domain order of the nominal repetition. That is, the RV sequence is cyclically mapped to the nominal repetition transmission opportunities of the PUSCH.

Furthermore, RVs are cyclically mapped based on the actual repetitions or actual repetition transmission opportunities associated with each TRP. For ease of explanation, this term is referred to as "actual repetition transmission opportunity" below.

Figure 11 As shown, the mapping relationship between PUSCH and two TRPs is inter-nominal-repetition TRP mapping, that is, PUSCH is cyclically mapped (correlated) with two TRPs in units of nominal repetition transmission opportunities, and the RV sequence ( Figure 11 {0,0,0,0} in the RV sequence) is cyclically mapped to the actual repeated transmission opportunities of the PUSCH, that is, the mapping method of the RV sequence is actual-repetition based RV mapping.

[0152] exist Figures 9 to 11 In the example, only the mapping relationship between PUSCH and two TRPs is taken as the inter-nominal repetition TRP mapping (inter-nominal repetition TRP mapping) as an example. This application does not limit this. The TRP mapping method can also be inter-actual repetition TRP mapping. In addition, in addition to actual-repetition based RV mapping, the mapping method of the RV sequence can also be nominal-repetition based RVmapping. This application is not limited to this. The specific implementation method can refer to Figure 7 implementation.

[0153] In some embodiments of the present application, 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, wherein the first transmission opportunity refers to the transmission opportunity of the uplink data that is related to the first TRP of the two TRPs mentioned above, and the second transmission opportunity refers to the transmission opportunity of the uplink data that is related to the second TRP of the two TRPs mentioned above, that is, among the transmission opportunities of the uplink data, the RV of the transmission opportunity (first transmission opportunity) related to TRP#1 and the RV of the transmission opportunity (second transmission opportunity) related to TRP#2 are related. Thus, the terminal device can use the relationship between the two to improve the combining gain of the uplink data. This is because, compared to the case where there is no correlation between transmission opportunities related to different TRPs, the RV of the transmission opportunity related to TRP#1 and the RV of the transmission opportunity related to TRP#2 are related. In the scenario where the transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 are adjacent in the time domain and the probability of occlusion is low (that is, when there is a high probability that the adjacent transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 can be received at the same time), a higher combining gain can be achieved by optimizing the corresponding RV.

[0154] In some embodiments, the sequence number associated with the first transmission opportunity is the same as the sequence number associated with the second transmission opportunity. Here, the sequence number may be a nominal repetition sequence number corresponding to the transmission opportunity or an actual repetition sequence number corresponding to the transmission opportunity.

[0155] In some embodiments, the correlation between the RV of the first transmission opportunity of uplink data and the RV of the second transmission opportunity of 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. Thus, the network device can semi-statically adjust the RV of the PUSCH transmission opportunity corresponding to TRP#2 via RRC signaling based on actual conditions, thereby improving the combining gain of the corresponding uplink data signal and, in turn, improving system performance.

[0156] In the above embodiment, the difference may be an offset, such as Figures 6 to 9 RV shown s , can also refer to shift, such as Figure 10 RV shift shown.

[0157] In some embodiments, the correlation between the RV of the first transmission opportunity of uplink data and the RV of the second transmission opportunity of 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. Thus, the network device can flexibly indicate the corresponding RV based on each PUSCH transmission to obtain the maximum combining gain.

[0158] In the above embodiment, the PUSCH is applicable to dynamic scheduling, such as Figures 6 to 8 The scene shown.

[0159] For example, the difference is indicated by a corresponding unit in the TDRA field of the DCI signaling. Thus, there is no need to add an additional DCI field, which helps to reduce the DCI size and thus improve the reliability of the control channel.

[0160] For another example, the difference is indicated by a field in the DCI signaling, which is relatively simple, has low implementation difficulty and cost, and has little impact on standardization.

[0161] In some embodiments, the RV of the first transmission opportunity of the uplink data is correlated with the RV of the second transmission opportunity of the uplink data, which means that the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity. This method does not require additional instructions, saving instruction overhead. In addition, this method is relatively simple and easy to implement in hardware.

[0162] In some embodiments, the RV of the first transmission opportunity of uplink data is related to the RV of the second transmission opportunity of uplink data, which means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined based on the third transmission opportunity; wherein the third transmission opportunity refers to the last transmission opportunity related to the first TRP of the two TRPs before the second transmission opportunity. Similarly, this method does not require additional instructions, saving indication overhead; in addition, when the occlusion probability is small, that is, when there is a high probability that the adjacent transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 can be received at the same time, this method achieves a higher combining gain by specifying the relationship between the RVs of adjacent transmission opportunities.

[0163] In the embodiments of the present application, in some embodiments, such as Figure 5 As shown, the method may further include:

[0164] 502: The terminal device receives indication information; wherein, the indication information indicates the RV of the transmission opportunity of uplink data related to the first TRP of two TRPs; the indication information is included in DCI signaling or RRC signaling.

[0165] According to the above embodiment, the terminal device can obtain the RV of the PUSCH transmission opportunity related to the first TRP (TRP#1) of the two TRPs, so that the terminal device can determine the RV of the transmission opportunity related to the second TRP (TRP#2) of the two TRPs based on this.

[0166] For example, in the previous embodiment, the RV of the transmission opportunity associated with TRP#1 and the RV of the transmission opportunity associated with TRP#2 are correlated. The terminal device can utilize this correlation and, based on the received indication information, determine the RV of the transmission opportunity associated with TRP#2 according to the RV of the transmission opportunity associated with TRP#1. The meaning of this correlation has been previously explained and is incorporated herein, so its explanation is omitted.

[0167] Below Figure 6 As an example, the above instructions are explained.

[0239] like Figure 9As shown, for the case where the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined according to the third transmission opportunity (default #2), in some embodiments, rv id Indicated by the scheduling DCI corresponding to PUSCH (RV field). s Determined by the last actual repeated transmission opportunity associated with TRP#1 before this second transmission opportunity.

[0240] For example, in Figure 9 For the second transmission opportunity with sequence number 0 (ie n=0), before the second transmission opportunity, according to Figure 9 , the transmission opportunity (the third transmission opportunity) corresponding to the last actual repetition (Rep#1) of TRP#1 has an RV of 0, and the RV of the 0th actual repetition associated with TRP#2 is the next RV of 0, which is 2 (according to the order of 0-2-3-1). Therefore, rv s =2-0=2. The RV of other transmission opportunities is based on rv s = 2. In addition, the RV sequence applied to the actual repeated transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the actual repeated transmission opportunity associated with TRP#2 is also {0, 2, 3, 1}.

[0241] like Figure 9 As shown, for the case where 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 according to the following Table 17 and Table 18. s Configured by RRC signaling. Figure 9 In the example, rv s =0.

[0246]

[0247] Reference Figure 9 It can be seen from Table 17 that the RV of the 0th actual repeated transmission opportunity associated with TRP#1 is 0, and since in this example, rv s=0, then according to Table 18, the RV sequence applied to the 0th actual repeated transmission opportunity associated with TRP#2 is also 0. In addition, the RV sequence applied to the actual repeated transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the actual repeated transmission opportunity associated with TRP#2 is also {0, 2, 3, 1}.

[0248] Below Figure 10 As an example, the above instructions are explained.

[0249] like Figure 10 As shown, for the case where 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 according to Table 19, that is, for uplink data, the RV of the nth actual repeated transmission opportunity associated with TRP#1 is the same as the RV of the nth actual repeated transmission opportunity associated with TRP#2.

[0250] Table 19 below shows the RV sequence applied to the nth actual repeated transmission opportunity associated with TRP#1 or TRP#2. Figure 10 In the example shown, n = 0, 1, 2, ...; for example, the second actual repetition associated with TRP#1 is Actual Rep#1. The first actual repetition associated with TRP#2 is Actual Rep#2. Note that it is necessary to consider the transmission opportunities not used to send data ( Figure 10 dotted line part).

[0251] Table 19:

[0252]

[0253] Reference Figure 10 As can be seen from Table 19, the RV of the zeroth actually repeated transmission opportunity associated with TRP#1 and the RV of the zeroth actually repeated transmission opportunity associated with TRP#2 are the same, both 0. Furthermore, the RV sequence applied to the actually repeated transmission opportunity associated with TRP#1 is {0, 3, 0, 3}; the RV sequence applied to the actually repeated transmission opportunity associated with TRP#2 is also {0, 3, 0, 3}.

[0254] like Figure 10 As shown, for the case where the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined according to the third transmission opportunity (default #2), in some embodiments, rv id Indicated by the scheduling DCI corresponding to PUSCH (RV field). RVshift is determined by the last actual repeated transmission opportunity associated with TRP#1 before the second transmission opportunity.

[0255] For example, in Figure 10 For the second transmission opportunity with sequence number 0 (ie n=0), before the second transmission opportunity, according to Figure 10 , the transmission opportunity (the third transmission opportunity) corresponding to the last actual repetition (Rep#1) of TRP#1 has an RV of 0. Then the RV of the 0th actual repetition associated with TRP#2 is the next RV after 0, that is, 3 (according to the order of 0-3-0-3). Therefore, RVshift=1 (that is, 3 is used as the starting RV, as shown in Table 21). The RVs of other transmission opportunities can be derived by referring to Table 21 based on RVshift=1. In addition, the RV sequence applied to the actual repetition transmission opportunity associated with TRP#1 is {0,3,0,3}; the RV sequence applied to the actual repetition transmission opportunity associated with TRP#2 is also {0,3,0,3}.

[0256] like Figure 10 As shown, for the case where 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 according to Table 20 and Table 21. RVshift is configured by RRC signaling. Figure 10 In the example, RVshift=1.

[0257] The following Table 20 shows the RV of the n-th actually repeated transmission opportunity associated with TRP#1. The following Table 21 shows the RV of the n-th actually repeated transmission opportunity associated with TRP#2.

[0258] Table 20:

[0259]

[0260] Table 21:

[0261]

[0262] Reference Figure 10 It can be seen that according to Table 20, the RV applied to the 0th actual repeated transmission opportunity associated with TRP#1 is 0, and since RVshift = 1 in this example, according to Table 21, the RV applied to the 0th actual repeated transmission opportunity associated with TRP#2 is 3. In addition, the RV sequence applied to the actual repeated transmission opportunity associated with TRP#1 is {0, 3, 0, 3}; the RV sequence applied to the actual repeated transmission opportunity associated with TRP#2 is also {0, 3, 0, 3}.

[0263] Below Figure 11 As an example, the above instructions are explained.

[0264] like Figure 11 As shown in FIG, the RV sequence applied to the actual repeated transmission opportunity associated with TRP#1 is {0,0,0,0}; the RV sequence applied to the actual repeated 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 0. It should be noted that in Figure 11 In the example shown, n = 0, 1, 2, ...; for example, the second actual repetition associated with TRP#1 is Actual Rep#1. The first actual repetition associated with TRP#2 is Actual Rep#2. Note that it is necessary to consider the transmission opportunities not used to send data ( Figure 11 dotted line part).

[0265] In some embodiments of the above embodiments, the RV sequence applied to the transmission opportunity associated with the first TRP of the two TRPs in at least one transmission opportunity for uplink data is the same as the RV sequence applied to the transmission opportunity associated with the second TRP of the two TRPs in at least one transmission opportunity for uplink data. Thus, the same RV sequence can be applied to multiple TRPs, thereby saving signaling overhead.

[0266] In some embodiments of the present application, uplink data starts from an actual repeated transmission opportunity associated with the first TRP (TRP#1) of the two TRPs and corresponding to an RV of 0. Thus, the terminal device is only allowed to start PUSCH transmission on transmission opportunities with relatively high reliability. The advantage of this is that, when the CG is large, the network device only needs to assume that PUSCH transmission may occur in a part of the PUSCH transmission opportunities. In this way, the number of blind detections on the network side can be reduced, and the design complexity of the network side can be reduced.

[0267] by Figure 10 For example, PUSCH only starts from certain PUSCH transmission opportunities, that is, if the configured RV sequence is {0,3,0,3}, the initial transmission of the configured permitted transmission block can start from any actual repeated transmission opportunity associated with RV=0 and TRP#1.

[0268] like Figure 10 As shown, since RV=0, PUSCH can be sent starting from the 0th or 2nd actual repeated transmission opportunity associated with TRP#1.

[0269] by Figure 11For example, PUSCH only starts from certain PUSCH transmission opportunities, that is, if the configured RV sequence is {0,0,0,0}, the initial transmission of the configured permitted transmission block can start from any actual repeated transmission opportunity associated with RV=0 and TRP#1.

[0270] like Figure 11 As shown, since RV=0, PUSCH is sent starting from the 0th, 1st, 2nd or 3rd actual repeated transmission opportunity associated with TRP#1.

[0271] In some embodiments of the present application, at least one transmission opportunity of uplink data is associated with two TRPs, which means:

[0272] At least one transmission opportunity of the uplink data is associated (mapped) with the two TRPs respectively in units of at least one nominally repeated transmission opportunity of the uplink data; or

[0273] At least one transmission opportunity of the uplink data is associated (mapped) with the two TRPs respectively in units of at least one actually repeated transmission opportunity of the uplink data; or

[0274] At least one transmission opportunity of uplink data is respectively associated (mapped) with the above two TRPs in units of at least one time slot.

[0275] This application does not limit the specific implementation methods.

[0276] In the embodiment of the present application, TRP is equivalent to at least one of the following concepts:

[0277] Transmission configuration indication state (TCI state);

[0278] Spatial relation;

[0279] Reference signal;

[0280] Reference signal group;

[0281] SRS resource group (the resource group contains one or more SRS resources);

[0282] Spatial domain filter;

[0283] Power control parameter; and

[0284] A group of time alignment (TA) related parameters.

[0285] For the specific meanings of the above concepts, please refer to the relevant technologies and the explanation is omitted here.

[0286] For example, at least one transmission opportunity of PUSCH is related to at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being related to at least two TCI states, that is, the terminal device sends the PUSCH according to the parameters corresponding to the above at least two TCI states.

[0287] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two spatial relationships.

[0288] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two reference signals. Here, the reference signal can be a path loss reference signal (pathloss RS), or a CSI-RS (Channel State Information Reference Signal), SSB (Synchronization Signal Block), SRS (Sounding Reference Signal), etc., but the present application is not limited thereto.

[0289] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two reference signal groups. A reference signal group is one or more reference signals (RS). Here, the reference signal can be a path loss reference signal (pathloss RS), or a CSI-RS (Channel State Information Reference Signal), SSB (Synchronization Signal Block), SRS (Sounding Reference Signal), etc., but the present application is not limited to this.

[0290] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two spatial filters.

[0291] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two power control parameters.

[0292] It is worth noting that the above Figure 5 The embodiments of the present application are only schematically described, but the present application is not limited thereto. For example, the execution order of the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the above appended examples. Figure 5 Records of.

[0293] According to the method of the embodiment of the present application, it can be ensured that in the event of occlusion, even if only a portion of the TRP can work, a higher combining gain can be achieved compared to the case where the RV is unrelated to the TRP. This is because this method allows the RV of the transmission opportunity of the above-mentioned uplink data to be adjusted according to the information of the relevant TRP. That is to say, when the TRP corresponding to the transmission opportunity of the above-mentioned uplink data is different, or when the probability of the corresponding TRP being blocked changes, the RV of each transmission opportunity can be flexibly and optimally determined based on the relevant information of the TRP, thereby improving system performance.

[0294] Embodiments of the second aspect

[0295] The embodiment of the present application provides a method for sending uplink data, which is described from the perspective of the terminal device. Unlike the embodiment of the first aspect, the method of the embodiment of the present application is applicable to sending uplink data (PUSCH) in the manner of PUSCH repetition type A, wherein the same contents as the embodiment of the first aspect are not repeated. Figure 1 The scenario of dynamically scheduled PUSCH and Figure 2 The scenario of configured grant PUSCH is taken as an example for explanation.

[0296] Figure 12 : is a schematic diagram of a method for sending uplink data according to an embodiment of the present application. Figure 12 As shown, the method includes:

[0297] 1201: The terminal device sends uplink data in PUSCH repetition type A mode, at least one transmission opportunity of the uplink data is related to two TRPs, and an RV of the at least one transmission opportunity of the uplink data is derived based on the two TRPs.

[0298] According to the method of the embodiment of the present application, it can be ensured that in the event of occlusion, even if only a part of the TRP can work, a higher merging gain can be achieved compared to the case where the RV version is unrelated to the TRP. This is because this method allows the RV version of the transmission opportunity of the above-mentioned uplink data to be adjusted according to the information of the relevant TRP. That is to say, when the TRP corresponding to the transmission opportunity of the above-mentioned uplink data is different, or when the probability of the corresponding TRP being blocked changes, the RV version of each transmission opportunity can be flexibly determined based on the relevant information of the TRP to optimize the system performance.

[0299] In some embodiments, the RV of at least one transmission opportunity of uplink data is derived based on the two TRPs, which means that:

[0300] The RV of the transmission opportunity associated with the first of the two TRPs in the at least one transmission opportunity for the uplink data is determined by the time domain sequence of the transmission opportunities associated with the first TRP; and the RV of the transmission opportunity associated with the second of the two TRPs in the at least one transmission opportunity for the uplink data is determined by the time domain sequence of the transmission opportunities associated with the second TRP. In other words, the RV sequence is cyclically mapped according to the transmission opportunities of the PUSCH.

[0301] Figure 13 This is a schematic diagram of an example of the mapping relationship between the dynamically scheduled PUSCH and the RV sequence. Figure 13 As shown, the mapping relationship between PUSCH and two TRPs is inter-slot TRP mapping, that is, PUSCH is cyclically mapped (correlated) with two TRPs in units of one transmission opportunity, and the RV sequence ( Figure 13 {0, 2, 3, 1}) are cyclically mapped to the transmission opportunities in each time slot of the PUSCH, that is, the mapping method of the RV sequence is slot based RV mapping.

[0302] exist Figure 13 In the example, the RV sequence applied to the transmission opportunity associated with TRP#1 and the RV sequence applied to the transmission opportunity associated with TRP#2 are the same, both {0, 2, 3, 1}. In addition, the difference (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. In addition, RVs are cyclically mapped according to the transmission opportunities associated with each TRP.

[0303] Figure 14 This is a schematic diagram of an example of the mapping relationship between the configured permitted PUSCH and the RV sequence. Figure 14 As shown, the TRP mapping mode of PUSCH and the mapping mode of RV sequence are the same as Figure 13 same.

[0304] exist Figure 14 In the example, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, which is {0, 2, 3, 1}. Moreover, the difference (offset) between the RV of the PUSCH transmission opportunity n associated with TRP#1 and the RV of the PUSCH transmission opportunity n associated with TRP#2 is rv s Furthermore, RVs are mapped cyclically according to the transmission opportunities associated with each TRP.

[0305] Figure 15 FIG. 1 is a schematic diagram of another example of the mapping relationship between the configured permitted PUSCH and the RV sequence. Figure 15 As shown, the TRP mapping mode of PUSCH and the mapping mode of RV sequence are the same as Figure 13 same.

[0306] exist Figure 15 In the example, with Figure 14 The difference from the example is that the RV sequence corresponding to TRP#1 and the RV sequence corresponding to TRP#2 are the same, both {0, 3, 0, 3}. In addition, the difference (cyclic shift) between the RV of the PUSCH transmission opportunity n associated with TRP#1 and the RV of the PUSCH transmission opportunity n associated with TRP#2 is RVshift.

[0307] Figure 16 FIG. 1 is a schematic diagram of another example of the mapping relationship between the configured permitted PUSCH and the RV sequence. Figure 16 As shown, the RV sequence corresponding to TRP#1 is the same as the RV sequence corresponding to TRP#2, both of which are {0,0,0,0}.

[0308] 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, wherein the first transmission opportunity refers to the transmission opportunity of the uplink data that is related to the first TRP of the two TRPs mentioned above, and the second transmission opportunity refers to the transmission opportunity of the uplink data that is related to the second TRP of the two TRPs mentioned above, that is, among the transmission opportunities of the uplink data, the RV of the transmission opportunity related to TRP#1 is related to the RV of the transmission opportunity related to TRP#2. Thus, the terminal device can use the relationship between the two to improve the combining gain of the uplink data. This is because, compared to the case where there is no correlation between 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. In the scenario where the transmission opportunity of TRP#1 and the transmission opportunity related to TRP#2 are adjacent in the time domain and the probability of occlusion is low (that is, when there is a high probability that the adjacent transmission opportunity related to TRP#1 and the transmission opportunity related to TRP#2 can be received at the same time), a higher combining gain can be achieved by optimizing the corresponding RV version.

[0309] In some embodiments, the sequence number associated with the first transmission opportunity is the same as the sequence number associated with the second transmission opportunity. Here, the sequence number is the sequence number corresponding to the transmission opportunity.

[0310] In some embodiments, the correlation between the RV of the first transmission opportunity of uplink data and the RV of the second transmission opportunity of 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. Thus, the network device can semi-statically adjust the RV of the PUSCH transmission opportunity corresponding to TRP#2 via RRC signaling based on actual conditions, thereby improving the combining gain of the corresponding uplink data signal and, in turn, improving system performance.

[0311] In the above embodiment, the difference may be an offset, such as Figure 13 and Figure 14 RV shown s , can also refer to shift, such as Figure 15 RV shift shown.

[0312] In some embodiments, the correlation between the RV of the first transmission opportunity of uplink data and the RV of the second transmission opportunity of 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. Thus, the network device can flexibly indicate the corresponding RV according to each PUSCH transmission.

[0313] In the above embodiment, the PUSCH is applicable to dynamic scheduling, such as Figure 13 The scene shown.

[0314] For example, the difference is indicated by a corresponding unit in the TDRA field of the DCI signaling. Thus, there is no need to add an additional DCI field, which helps to reduce the DCI size and thus improve the reliability of the control channel.

[0315] For another example, the difference is indicated by a field in the DCI signaling, which is relatively simple, has low implementation difficulty and cost, and has little impact on standardization.

[0316] In some embodiments, the RV of the first transmission opportunity of the uplink data is correlated with the RV of the second transmission opportunity of the uplink data, which means that the RV of the first transmission opportunity is the same as the RV of the second transmission opportunity. This method does not require additional instructions, saving instruction overhead. In addition, this method is relatively simple and easy to implement in hardware.

[0317] In some embodiments, the RV of the first transmission opportunity of uplink data is related to the RV of the second transmission opportunity of uplink data, which means that the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined according to the third transmission opportunity; wherein the third transmission opportunity refers to the last transmission opportunity related to the first TRP of the two TRPs before the second transmission opportunity. Similarly, this method does not require additional indications, saving indication overhead; in addition, when the occlusion probability is small (that is, when there is a high probability of simultaneously receiving adjacent transmission opportunities related to TRP#1 and transmission opportunities related to TRP#2), this method achieves higher combining gain by specifying the relationship between the RV versions of adjacent transmission opportunities.

[0318] In the embodiments of the present application, in some embodiments, such as Figure 12 As shown, the method may further include:

[0319] 1202: The terminal device receives indication information; wherein, the indication information indicates the RV of the transmission opportunity of uplink data related to the first TRP of the two TRPs; the indication information is included in DCI signaling or RRC signaling.

[0320] According to the above embodiment, the terminal device can obtain the RV of the PUSCH transmission opportunity related to the first TRP (TRP#1) of the two TRPs, so that the terminal device can determine the RV of the transmission opportunity related to the second TRP (TRP#2) of the two TRPs based on this.

[0321] For example, in the previous embodiment, the RV of the transmission opportunity associated with TRP#1 and the RV of the transmission opportunity associated with TRP#2 are correlated. The terminal device can utilize this correlation and, based on the received indication information, determine the RV of the transmission opportunity associated with TRP#2 according to the RV of the transmission opportunity associated with TRP#1. The meaning of this correlation has been previously explained and is incorporated herein, so its explanation is omitted.

[0322] Below Figure 13 As an example, the above instructions are explained.

[0323] like Figure 13 As shown, for the case where 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 The scheduling DCI corresponding to PUSCH indicates (RV field); rv s Dynamically indicated by DCI, more specifically, for example, rv s It is indicated by a field in the DCI.

Table 23 below shows the RV sequence applied to the nth transmission opportunity associated with TRP#2, or Table 33 shows the RV of the nth transmission opportunity associated with TRP#2. It should be noted that in Figure 13 In the example shown, 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.

In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 2, 3, 1}.

In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is also {0, 2, 3, 1}.

[0335] like Figure 13 As shown, for the case where the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined according to the third transmission opportunity (default #2), in some embodiments, rv id Indicated by the scheduling DCI corresponding to PUSCH (RV field). s Determined by the transmission opportunity associated with TRP#1 before this second transmission opportunity.

[0336] For example, in Figure 13 For the second transmission opportunity with sequence number 0 (ie n=0), before the second transmission opportunity, according to Figure 13 , the transmission opportunity corresponding to TRP#1 (the third transmission opportunity) has an RV of 0, and the RV of the 0th transmission opportunity associated with TRP#2 is the next RV of 0, which is 2 (according to the order of 0-2-3-1). Therefore, rv s=2-0=2. The RV of other transmission opportunities is based on rv s = 2. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 2, 3, 1}.

[0355] Reference Figure 14 It can be seen that the RV applied to the 0th transmission opportunity associated with TRP#1 is the same as the RV applied to the 0th transmission opportunity associated with TRP#2, both of which are 0. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is also {0, 2, 3, 1}.

[0356] like Figure 14 As shown, for the case where the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined based on the third transmission opportunity (default #2), in some embodiments, the RV can be determined according to the following Table 40 and Table 41. s Determined by the transmission opportunity associated with TRP#1 before this second transmission opportunity.

[0357] For example, in Figure 14For the second transmission opportunity with sequence number 0 (ie n=0), before the second transmission opportunity, according to Figure 14 , the transmission opportunity corresponding to TRP#1 (the third transmission opportunity) has an RV of 0, and the RV of the 0th transmission opportunity associated with TRP#2 is the next RV of 0, which is 2 (according to the order of 0-2-3-1). Therefore, rv s =2-0=2. The RV of other transmission opportunities is based on rv s = 2. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 2, 3, 1}.

[0358] The following Table 30 shows the RV applied to the nth transmission opportunity associated with TRP#1. The following Table 31 shows the RV applied to the nth transmission opportunity associated with TRP#2.

[0362]

[0363] Reference Figure 14 It can be seen from Table 30 that the RV applied to the 0th transmission opportunity associated with TRP#1 is 0, and since in this example, rv s =2, then according to Table 31, the RV sequence applied to the 0th transmission opportunity associated with TRP#2 is 2. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 2, 3, 1}.

[0364] like Figure 14 As shown, for the case where 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 according to the following Table 32 and Table 33. s Configured by RRC signaling.

[0369]

[0370] Reference Figure 14 It can be seen from Table 32 that the RV applied to the 0th transmission opportunity associated with TRP#1 is 0, and since in this example, rv s =2, then according to Table 33, the RV applied to the 0th transmission opportunity associated with TRP#2 is 2. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 2, 3, 1}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 2, 3, 1}.

[0371] Below Figure 15 As an example, the above instructions are explained.

[0372] like Figure 15 As shown, for the case where 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 according to 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.

[0373] Table 34 below shows the RV applied to the nth transmission opportunity associated with TRP#1 or TRP#2.

[0374] Table 34:

[0375]

[0376] Reference Figure 15 As can be seen from Table 34, the RV applied to the 0th transmission opportunity associated with TRP#1 and the RV applied to the 0th transmission opportunity associated with TRP#2 are the same, both 0. Furthermore, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 3, 0, 3}; the RV sequence applied to the transmission opportunity associated with TRP#2 is also {0, 3, 0, 3}.

[0377] like Figure 15 As shown in FIG, for the case where the difference between the RV of the first transmission opportunity and the RV of the second transmission opportunity is determined based on the third transmission opportunity (default #2), in some embodiments, the RV may be determined according to the following Table 35 and Table 36. In this case, the RVshift is determined by the transmission opportunity associated with TRP #1 before the second transmission opportunity.

[0378] For example, in Figure 15 For the second transmission opportunity with sequence number 0 (ie n=0), before the second transmission opportunity, according to Figure 15 , the transmission opportunity corresponding to TRP#1 (the third transmission opportunity) has an RV of 0. Therefore, the RV of the 0th transmission opportunity associated with TRP#2 is the RV next to 0, that is, 3 (according to the sequence 0-3-0-3), so RVshift = 1. The RVs of other transmission opportunities can be calculated using RVshift = 1. Furthermore, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 3, 0, 3}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 3, 0, 3}.

[0379] The following Table 35 shows the RV applied to the nth transmission opportunity associated with TRP#1. The following Table 36 shows the RV applied to the nth transmission opportunity associated with TRP#2.

[0380] Table 35:

[0381]

[0382] Table 36:

[0383]

[0384] Reference Figure 15 It can be seen that according to Table 35, the RV applied to the 0th transmission opportunity associated with TRP#1 is 0, and since RVshift = 1 in this example, according to Table 36, the RV applied to the 0th transmission opportunity associated with TRP#2 is 3. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 3, 0, 3}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 3, 0, 3}.

[0385] like Figure 15 As shown, for the case where 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 according to the following Table 37 and Table 38. RVshift is configured by RRC signaling. Figure 15 In the example, RVshift=1.

[0386] The following Table 37 shows the RV applied to the nth transmission opportunity associated with TRP#1. The following Table 38 shows the RV applied to the nth transmission opportunity associated with TRP#2.

[0387] Table 37:

[0388]

[0389] Table 38:

[0390]

[0391] Reference Figure 15 It can be seen that according to Table 37, the RV applied to the 0th transmission opportunity associated with TRP#1 is 0, and since RVshift = 1 in this example, according to Table 38, the RV applied to the 0th transmission opportunity associated with TRP#2 is 3. In addition, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0, 3, 0, 3}; the RV sequence applied to the transmission opportunity associated with TRP#2 is {0, 3, 0, 3}.

[0392] Below Figure 16 As an example, the above instructions are explained.

[0393] like Figure 16 As shown in FIG, the RV sequence applied to the transmission opportunity associated with TRP#1 is {0,0,0,0}, and the RV sequence applied to 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 0. It should be noted that Figure 16 In the example shown, 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.

[0394] In some embodiments of the above embodiments, the RV sequence applied to the transmission opportunity associated with the first TRP of the two TRPs in at least one transmission opportunity for uplink data is the same as the RV sequence applied to the transmission opportunity associated with the second TRP of the two TRPs in at least one transmission opportunity for uplink data. Thus, multiple TRPs can share the same RV sequence, saving signaling overhead.

[0395] In some embodiments of the present application, uplink data starts from a transmission opportunity associated with the first TRP (TRP#1) of the two TRPs and corresponding to an RV of 0. Thus, the terminal device is only allowed to start PUSCH transmission on transmission opportunities with relatively high reliability. The advantage of this is that, when the CG is large, the network device only needs to assume that PUSCH transmission may occur in a part of the PUSCH transmission opportunities. In this way, the number of blind detections on the network side can be reduced, and the design complexity of the network side can be reduced.

[0396] by Figure 15For example, PUSCH only starts from certain PUSCH transmission opportunities, that is, if the configured RV sequence is {0,3,0,3}, the initial transmission of the configured permitted transport block can start from any transmission opportunity associated with RV=0 and TRP#1.

[0397] like Figure 15 As shown, since RV=0, PUSCH can be sent starting from the 0th transmission opportunity (Rep#1).

[0398] by Figure 16 For example, PUSCH only starts from certain PUSCH transmission opportunities, that is, if the configured RV sequence is {0,0,0,0}, the initial transmission of the configured permitted transmission block can start from any actual repeated transmission opportunity associated with RV=0 and TRP#1.

[0399] like Figure 16 As shown, since RV=0, PUSCH can be sent starting from the 0th or 2nd transmission opportunity (Rep#1 or Rep#3).

[0400] In some embodiments of the present application, at least one transmission opportunity of uplink data is associated with two TRPs, which means:

[0401] At least one transmission opportunity of uplink data is associated (mapped) with the two TRPs in units of at least one time slot; or

[0402] At least one transmission opportunity for uplink data is respectively associated (mapped) with the two TRPs in units of at least one time domain portion within a time slot.

[0403] This application does not limit the specific implementation methods.

[0404] In the embodiment of the present application, TRP is equivalent to at least one of the following concepts:

[0405] Transmission configuration indication state (TCI state);

[0406] Spatial relation;

[0407] Reference signal;

[0408] Reference signal group;

[0409] SRS resource group (the resource group contains one or more SRS resources);

[0410] Spatial domain filter;

[0411] Power control parameter; and

[0412] A group of time alignment (TA) related parameters.

[0413] For the specific meanings of the above concepts, please refer to the relevant technologies and the explanation is omitted here.

[0414] For example, at least one transmission opportunity of PUSCH is related to at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being related to at least two TCI states, that is, the terminal device sends the PUSCH according to the parameters corresponding to the above at least two TCI states.

[0415] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two spatial relationships.

[0416] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two reference signals. Here, the reference signal can be a path loss reference signal (pathloss RS), or a CSI-RS (Channel State Information Reference Signal), SSB (Synchronization Signal Block), SRS (Sounding Reference Signal), etc., but the present application is not limited thereto.

[0417] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two reference signal groups. A reference signal group is one or more reference signals (RS). Here, the reference signal can be a path loss reference signal (pathloss RS), or a CSI-RS (Channel State Information Reference Signal), SSB (Synchronization Signal Block), SRS (Sounding Reference Signal), etc., but the present application is not limited to this.

[0418] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two spatial filters.

[0419] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two power control parameters.

[0420] It is worth noting that the above Figure 12 The embodiments of the present application are only schematically described, but the present application is not limited thereto. For example, the execution order of the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the above appended examples. Figure 12 Records of.

[0421] According to the method of the embodiment of the present application, it can be ensured that in the event of occlusion, even if only a part of the TRP can work, a higher merging gain can be achieved compared to the case where the RV version is unrelated to the TRP. This is because this method allows the RV version of the transmission opportunity of the above-mentioned uplink data to be adjusted according to the information of the relevant TRP. That is to say, when the TRP corresponding to the transmission opportunity of the above-mentioned uplink data is different, or when the probability of the corresponding TRP being blocked changes, the RV version of each transmission opportunity can be flexibly determined based on the relevant information of the TRP to optimize the system performance.

[0422] Embodiments of the third aspect

[0423] An embodiment of the present application provides a method for sending uplink data, which is described from the terminal device side.

[0424] Figure 17 Schematic diagram of a method for sending uplink data according to an embodiment of the present application. Figure 17 As shown, the method includes:

[0425] 1701: The terminal device sends uplink data, and at least one transmission opportunity of the uplink data is related to two TRPs; wherein the terminal device performs frequency hopping on the transmission of the uplink data according to a transmission opportunity related to one of the two TRPs in the at least one transmission opportunity of the uplink data.

[0426] According to the method of the embodiment of the present application, it can be ensured that in the event of obstruction, even if only a part of the TRP can work, the frequency domain diversity gain can be better utilized compared to the case where the uplink data frequency hopping is unrelated to the TRP. This is because this method can adjust the frequency hopping mode of the transmission opportunity of the above-mentioned uplink data according to the information of the relevant TRP. That is to say, when the TRP corresponding to the transmission opportunity of the above-mentioned uplink data is different, or when the probability of the corresponding TRP being obstructed changes, the frequency hopping mode of each transmission opportunity can be flexibly and optimally determined based on the relevant information of the TRP, thereby improving the frequency domain diversity gain and thus improving the system performance.

[0427] In some embodiments, the transmission opportunity associated with one of the two TRPs in the at least one transmission opportunity for uplink data is:

[0428] For uplink data sent in PUSCH repetition type B mode, the nominally repeated transmission opportunity associated with one of the two TRPs in at least one transmission opportunity of the uplink data; or

[0429] For uplink data sent in PUSCH repetition type B mode, the actual repeated transmission opportunity associated with one of the two TRPs in at least one transmission opportunity of the uplink data; or

[0430] For uplink data sent in PUSCH repetition type A, at least one transmission opportunity of uplink data in at least one time slot is a transmission opportunity associated with one of the two TRPs.

[0431] In some embodiments, performing frequency hopping refers to performing frequency hopping according to the nominal repetition of uplink data. That is, for uplink data transmitted in PUSCH repetition type B, frequency hopping is performed according to the nominal repetition of the uplink data or the transmission opportunity of the nominal repetition.

[0432] In some embodiments, performing frequency hopping refers to performing frequency hopping according to actual repetition of uplink data. That is, for uplink data sent in PUSCH repetition type B, frequency hopping is performed according to actual repetition or actual repetition transmission opportunity of the uplink data.

[0433] In some embodiments, performing frequency hopping means performing frequency hopping according to the time slot in which the uplink data is located. That is, for uplink data sent in PUSCH repetition type B or uplink data sent in PUSCH repetition type A, frequency hopping is performed according to transmission opportunities in one or more time slots of the uplink data.

[0434] In some embodiments, performing frequency hopping means performing frequency hopping according to a time domain portion corresponding to the uplink data within a time slot in which the uplink data is located. That is, for uplink data transmitted in PUSCH repetition type A, frequency hopping is performed according to a time domain portion corresponding to the uplink data within a time slot in which the uplink data is located.

[0435] Figure 18 is a schematic diagram of an example of a mapping relationship between a dynamically scheduled or configured PUSCH and a frequency hopping pattern, and Figure 18 The example corresponds to uplink data sent in PUSCH repetition type B.

[0436] like Figure 18 As shown, the frequency hopping pattern corresponding to TRP#1 is the same as the frequency hopping pattern corresponding to TRP#2. Specifically, the uplink data frequency hops in units of the nominal repetition associated with TRP#1, i.e., the frequency hopping mode is inter-repetition frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is 2. Similarly, the uplink data frequency hops in units of the nominal repetition associated with TRP#2, the frequency hopping mode is also inter-repetition frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is also 2.

[0437] In addition, the frequency domain position of the starting nominal repetition corresponding to TRP#1 is the same as the frequency domain position of the starting nominal repetition corresponding to TRP#2.

[0438] In addition, the frequency domain difference (frequency offset) between the two frequency hopping candidate positions corresponding to TRP#1 is the same as the frequency domain difference between the two frequency hopping candidate positions corresponding to TRP#2.

[0439] In addition, both TRP#1 and TRP#2 perform frequency hopping based on nominal repetitions, which means, for example, frequency hopping is performed on the nominal repetitions (Rep#1, Rep#3, Rep#5) corresponding to TRP#1 (corresponding to actual repetitions Rep#1, Rep#3, Rep#4, Rep#6), and frequency hopping is performed on the nominal repetitions (Rep#2, Rep#4) corresponding to TRP#2 (corresponding to actual repetitions Rep#2, Rep#5).

[0440] In addition, the mapping method between the uplink data and the TRP is inter-nominal-repetition TRPmapping, that is, the uplink data is mapped to different TRPs in sequence in units of nominal repetition.

[0441] Figure 19 is a schematic diagram of another example of a mapping relationship between a dynamically scheduled or configured PUSCH and a frequency hopping pattern, and Figure 19 The example corresponds to uplink data sent in PUSCH repetition type B.

[0442] like Figure 19 As shown, the frequency hopping pattern corresponding to TRP#1 is the same as the frequency hopping pattern corresponding to TRP#2. Specifically, the uplink data frequency hops based on the actual repetition associated with TRP#1, i.e., the frequency hopping mode is inter-repetition frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is 2. Similarly, the uplink data frequency hops based on the actual repetition associated with TRP#2, the frequency hopping mode is also inter-repetition frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is also 2.

[0443] In addition, the frequency domain position of the starting actual repetition corresponding to TRP#1 is the same as the frequency domain position of the starting actual repetition corresponding to TRP#2.

[0444] In addition, the frequency domain difference (frequency offset) between the two frequency hopping candidate positions corresponding to TRP#1 is the same as the frequency domain difference between the two frequency hopping candidate positions corresponding to TRP#2.

[0445] In addition, both TRP#1 and TRP#2 perform frequency hopping based on actual repetitions, which means, for example, frequency hopping is performed on the actual repetitions (Rep#1, Rep#3, Rep#4, Rep#6) corresponding to TRP#1, and frequency hopping is performed on the actual repetitions (Rep#2, Rep#5) corresponding to TRP#2.

[0446] In addition, the mapping method between the uplink data and the TRP is inter-nominal-repetition TRPmapping, that is, the uplink data is mapped to different TRPs in sequence in units of nominal repetition.

[0447] Figure 20 is a schematic diagram of another example of a mapping relationship between a dynamically scheduled or configured PUSCH and a frequency hopping pattern, and Figure 20 The example corresponds to uplink data sent in PUSCH repetition type B.

[0448] like Figure 20 As shown, the frequency hopping pattern corresponding to TRP#1 is the same as the frequency hopping pattern corresponding to TRP#2. Specifically, the uplink data frequency hops in units of the nominal repetition associated with TRP#1, i.e., the frequency hopping mode is inter-repetition frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is 2. Similarly, the uplink data frequency hops in units of the nominal repetition associated with TRP#2, the frequency hopping mode is also inter-repetition frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is also 2.

[0449] In addition, the frequency domain position of the starting nominal repetition corresponding to TRP#1 is the same as the frequency domain position of the starting nominal repetition corresponding to TRP#2.

[0450] In addition, the frequency domain difference (frequency offset) between the two frequency hopping candidate positions corresponding to TRP#1 is the same as the frequency domain difference between the two frequency hopping candidate positions corresponding to TRP#2.

[0451] In addition, both TRP#1 and TRP#2 perform frequency hopping based on actual repetitions, which means, for example, frequency hopping is performed on the actual repetitions (Rep#1, Rep#3, Rep#5) corresponding to TRP#1, and frequency hopping is performed on the actual repetitions (Rep#2, Rep#4, Rep#6) corresponding to TRP#2.

[0452] In addition, the mapping method between the uplink data and TRP is inter-actual-repetition TRPmapping, that is, the uplink data is mapped to different TRPs in sequence based on actual repetition.

[0453] Figure 21 is a schematic diagram of another example of a mapping relationship between a dynamically scheduled or configured PUSCH and a frequency hopping pattern, and Figure 21 The example corresponds to uplink data sent in PUSCH repetition type B.

[0454] like Figure 21 As shown, the frequency hopping pattern corresponding to TRP#1 is the same as the frequency hopping pattern corresponding to TRP#2. Specifically, the uplink data frequency hops in units of slots associated with TRP#1, i.e., the frequency hopping mode is inter-slot frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is 2. Similarly, the uplink data frequency hops in units of slots associated with TRP#2, and the frequency hopping mode is also inter-slot frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is also 2.

[0455] In addition, the frequency domain position of the starting slot corresponding to TRP#1 is the same as the frequency domain position of the starting slot corresponding to TRP#2.

[0456] In addition, the frequency domain difference (frequency offset) between the two frequency hopping candidate positions corresponding to TRP#1 is the same as the frequency domain difference between the two frequency hopping candidate positions corresponding to TRP#2.

[0457] In addition, both TRP#1 and TRP#2 perform frequency hopping according to time slots, which means, for example, frequency hopping is performed on the transmission opportunities (Rep#1, Rep#3) in slot n+k and the transmission opportunities (Rep#4, Rep#6) in slot n+k+1 corresponding to TRP#1; and frequency hopping is performed on the transmission opportunities (Rep#2) in slot n+k and the transmission opportunities (Rep#5) in slot n+k+1 corresponding to TRP#2.

[0458] In addition, the mapping method between the uplink data and the TRP is inter-nominal-repetition TRPmapping, that is, the uplink data is mapped to different TRPs in sequence in units of nominal repetition.

[0459] Figure 22 is a schematic diagram of an example of a mapping relationship between a dynamically scheduled or configured PUSCH and a frequency hopping pattern, and Figure 22 The example corresponds to uplink data sent in PUSCH repetition type A mode.

[0460] like Figure 22 As shown, the frequency hopping pattern corresponding to TRP#1 is the same as the frequency hopping pattern corresponding to TRP#2. Specifically, the uplink data frequency hops in units of slots associated with TRP#1, i.e., the frequency hopping mode is inter-slot frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is 2. Similarly, the uplink data frequency hops in units of slots associated with TRP#2, and the frequency hopping mode is also inter-slot frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for frequency hopping) is also 2.

[0461] In addition, the frequency domain position of the starting slot corresponding to TRP#1 is the same as the frequency domain position of the starting slot corresponding to TRP#2.

[0462] In addition, the frequency domain difference (frequency offset) between the two frequency hopping candidate positions corresponding to TRP#1 is the same as the frequency domain difference between the two frequency hopping candidate positions corresponding to TRP#2.

[0463] In addition, both TRP#1 and TRP#2 perform frequency hopping according to time slots, which means, for example, frequency hopping is performed on the transmission opportunity (Rep#1) in slot n+k and the transmission opportunity (Rep#3) in slot n+k+2 corresponding to TRP#1; and frequency hopping is performed on the transmission opportunity (Rep#2) in slot n+k+1 and the transmission opportunity (Rep#4) in slot n+k+3 corresponding to TRP#2.

[0464] In addition, the mapping mode between the uplink data and the TRP is inter-slot TRP mapping, that is, the uplink data is mapped to different TRPs in sequence in slot units.

[0465] Figure 23 is a schematic diagram of another example of a mapping relationship between a dynamically scheduled or configured PUSCH and a frequency hopping pattern, and Figure 23 The example corresponds to uplink data sent in PUSCH repetition type A.

[0466] like Figure 23 As shown, the frequency hopping pattern corresponding to TRP#1 is the same as the frequency hopping pattern corresponding to TRP#2. Specifically, the uplink data frequency hops based on the time domain portion within the slot associated with TRP#1, i.e., the frequency hopping mode is intra-slot frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for hopping) is 2. Similarly, the uplink data frequency hops based on the time domain portion within the slot associated with TRP#2, and the frequency hopping mode is also intra-slot frequency hopping, and the number of frequency hops (or the candidate frequency domain positions for hopping) is also 2.

[0467] In addition, the frequency domain position of the starting time domain portion corresponding to TRP#1 is the same as the frequency domain position of the starting time domain portion corresponding to TRP#2.

[0468] In addition, the frequency domain difference (frequency offset) between the two frequency hopping candidate positions corresponding to TRP#1 is the same as the frequency domain difference between the two frequency hopping candidate positions corresponding to TRP#2.

[0469] Furthermore, both TRP#1 and TRP#2 perform frequency hopping based on the time domain portion within the time slot. For example, frequency hopping is performed on the first time domain portion (symbols 1-7 of Rep#1) and the second time domain portion (symbols 8-14 of Rep#1) within slot n+k corresponding to TRP#1; and frequency hopping is performed on the first time domain portion (symbols 1-7 of Rep#2) and the second time domain portion (symbols 8-14 of Rep#2) within slot n+k+1 corresponding to TRP#2.

[0470] In addition, the mapping mode between the uplink data and the TRP is inter-slot TRP mapping, that is, the uplink data is mapped to different TRPs in sequence in slot units.

[0471] In the embodiments of the present application, in some embodiments, such as Figure 17 As shown, the method may further include:

[0472] 1702: The terminal device receives indication information, where the indication information indicates a frequency hopping mode, and the indication information is included in RRC signaling.

[0473] According to the method of the above embodiment, the network device can semi-statically adjust the frequency hopping mode corresponding to the TRP related to the uplink data through RRC signaling according to the channel conditions, thereby improving the system performance accordingly.

[0474] In some embodiments, the indication information indicates the frequency hopping mode of the uplink data associated with each of the two TRPs. That is, the frequency hopping mode is indicated for each TRP. The advantage of this method is that the network device can semi-statically adjust the frequency hopping mode corresponding to each TRP through RRC signaling based on the channel conditions of each TRP, thereby correspondingly improving system performance.

[0475] In some embodiments, the indication information indicates the frequency hopping pattern of the uplink data associated with the first of the two TRPs, and the frequency hopping pattern of the uplink data associated with the other TRPs in the 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) defaults to the same as the frequency hopping pattern of TRP#1. This method has the advantage of reducing indication signaling and saving overhead.

[0476] In this embodiment of the present application, the frequency hopping mode includes at least one of the following:

[0477] Whether to perform frequency hopping;

[0478] The number of hops;

[0479] The starting frequency domain position of frequency hopping;

[0480] Frequency domain offset of frequency hopping.

[0481] In some embodiments of the present application, a frequency hopping pattern applied to a transmission opportunity associated with the first of the two TRPs in at least one transmission opportunity for uplink data is the same as a frequency hopping pattern applied to a transmission opportunity associated with the second of the two TRPs in at least one transmission opportunity for uplink data. Thus, multiple TRPs use the same frequency hopping pattern, which can save signaling overhead.

[0483] At least one transmission opportunity of the uplink data is respectively associated with the two TRPs in units of at least one nominally repeated transmission opportunity of the uplink data; or

[0484] At least one transmission opportunity of the uplink data is respectively associated with the two TRPs in units of at least one actually repeated transmission opportunity of the uplink data; or

[0485] At least one transmission opportunity for uplink data is respectively associated with the two TRPs in units of at least one time slot.

[0486] This application does not limit the specific implementation methods.

[0488] Transmission configuration indication state (TCI state);

[0489] Spatial relation;

[0493] Spatial domain filter;

[0494] Power control parameter; and

[0495] A group of time alignment (TA) related parameters.

[0496] For the specific meanings of the above concepts, please refer to the relevant technologies and the explanation is omitted here.

[0497] For example, at least one transmission opportunity of PUSCH is related to at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being related to at least two TCI states, that is, the terminal device sends the PUSCH according to the parameters corresponding to the above at least two TCI states.

[0498] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two spatial relationships.

[0499] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two reference signals. Here, the reference signal can be a path loss reference signal (pathloss RS), or a CSI-RS (Channel State Information Reference Signal), SSB (Synchronization Signal Block), SRS (Sounding Reference Signal), etc., but the present application is not limited thereto.

[0500] For another example, at least one transmission opportunity of PUSCH is associated with at least two TRPs, which is equivalent to at least one transmission opportunity of PUSCH being associated with at least two reference signal groups. A reference signal group is one or more reference signals (RS). Here, the reference signal can be a path loss reference signal (pathloss RS), or a CSI-RS (Channel State Information Reference Signal), SSB (Synchronization Signal Block), SRS (Sounding Reference Signal), etc., but the present application is not limited to this.

[0504] According to the method of the embodiment of the present application, it can be ensured that in the event of obstruction, even if only a part of the TRP can work, the frequency domain diversity gain can be better utilized compared to the case where the uplink data frequency hopping is unrelated to the TRP. This is because this method can adjust the frequency hopping mode of the transmission opportunity of the above-mentioned uplink data according to the information of the relevant TRP. That is to say, when the TRP corresponding to the transmission opportunity of the above-mentioned uplink data is different, or when the probability of the corresponding TRP being obstructed changes, the frequency hopping mode of each transmission opportunity can be flexibly and optimally determined based on the relevant information of the TRP, thereby improving the frequency domain diversity gain and thus improving the system performance.
