Description

Method, device and system for reporting semi-persistent channel state information

technical field

This application relates to the field of communication.

Background technique

In order to meet the high reliability and low latency requirements of URLLC (Ultra-Relaible and Low Latency Communication) services, NR Rel-17 (New Wireless Version 17) introduces a corresponding uplink data transmission mechanism. This mechanism supports more flexible uplink data transmission, thereby reducing the delay of uplink data transmission.

Currently, the NR (New Radio) system supports the use of PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) to send semi-persistent channel state information (semi-persistent channel state information, SP-CSI). Specifically, the network device can activate signaling (SP-CSI-RNTI (SP-CSI-Radio Network Tempory Identity, Semi-persistent channel state information - DCI scrambled by wireless network temporary identifier), configure and activate the terminal device to feed back channel state information semi-persistently through PUSCH in a certain period.

In addition, the NR system supports two repetition methods, namely PUSCH repetition type A (PUSCH repetition Type A) and PUSCH repetition type B (PUSCH repetition Type B). Among them, PUSCH repetition Type B supports that according to specific conditions, the nominal repetition (nominal repetition) can be the same as the corresponding actual repetition (actual repetition); or the nominal repetition can be different from the corresponding actual repetition. Figure 1 is a schematic diagram of PUSCH repetition Type B. As shown in Figure 1, the nominal repetitions Rep#1, Rep#2, Rep#4, and Rep#5 are the same as the corresponding actual repetitions, and the nominal repetition Rep#3 is the same as the corresponding actual repetitions. Repeat differently. From another point of view, due to the slot format (slot format), slot boundary and other reasons of the nominal repetition of Rep#3, some symbols of Rep#3 cannot be used to send PUSCH. This situation is called Rep #3 split (segmentation).

It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present application, and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are known to those skilled in the art just because these solutions are described in the background technology section of this application.

Contents of the invention

The inventors found that currently, SP-CSI only supports sending through a single TRP (transmission/reception point, sending and receiving point) PUSCH, and does not support sending through multiple TRP PUSCHs. Wherein, single TRP PUSCH transmission means that one PUSCH corresponds to a set of precoding, spatial information or power control information, and corresponds to the transmission of one TRP. In addition, multi-TRP PUSCH transmission means that one PUSCH corresponds to two sets of precoding, two sets of spatial information or two sets of power control information, and corresponds to the transmission of two different TRPs.

However, the lack of support for sending SP-CSI through multiple TRP PUSCHs will reduce the ability of terminal devices to resist link occlusion. Specifically, since the terminal device only transmits SP-CSI through one TRP, when the uplink is blocked, the uplink transmission may fail. The solution to this problem is to use multiple TRP PUSCHs to send SP-CSI. That is, a terminal device can send SP-CSI to one TRP at one time, and then send the same SP-CSI to another TRP at another time. The advantage of this is that when the uplink corresponding to one TRP is blocked but the uplink corresponding to the other TRP is not blocked, the network device can still receive the SP-CSI. This enhances the robustness of sending uplink SP-CSI. However, there is currently no way to support SP-CSI to be sent through the above method, especially under what circumstances can or cannot send SP-CSI through multiple TRP PUSCHs.

Embodiments of the first aspect

An embodiment of the present application provides a method for reporting semi-persistent channel state information (SP-CSI), which is described from a terminal device side.

Fig. 2 is a schematic diagram of a method for reporting semi-persistent channel state information (SP-CSI) according to an embodiment of the present application. Referring to Fig. 2, the method includes:

201: The terminal device receives indication information; the indication information is used to activate SP-CSI report on PUSCH (SP-CSI report on PUSCH); wherein, the PUSCH corresponds to PUSCH repetition type A; the PUSCH corresponds to two repetitions ;

202: The terminal device ignores or does not send at least one of the two repetitions when the PUSCH meets at least one of the following conditions, the conditions including:

At least one of the two repetitions (repetition) of the PUSCH includes or multiplexes other uplink control information (UCI) except the SP-CSI; and

The two repetitions of the PUSCH contain/correspond to different UCI contents.

According to the embodiment of this application, when at least one of the two repetitions multiplexes UCI other than SP-CSI, or when the two repetitions contain/correspond to different UCI content, the network device receives the two repeated Sometimes, the two repetitions cannot be combined due to channel coding limitations. This will degrade the reception performance on the network side. Therefore, when "at least one of the two repetitions of PUSCH includes or multiplexes other UCI", and/or, "the UCI content contained in or corresponding to the two repetitions of PUSCH is different", at least ignore or not One of the two repetitions is sent. Thus, it is possible to avoid sending SP-CSI through multiple TRP PUSCHs when the above conditions are satisfied, and enhance the robustness of sending uplink SP-CSI. Moreover, according to the specific conditions of each PUSCH bearing UCI, the transmission mode of the corresponding PUSCH is determined, unnecessary uplink transmission is avoided, and the resource utilization rate of the system is improved.

In some embodiments, if the aforementioned PUSCH is scheduled by the aforementioned indication information, the terminal device ignores or does not send the second of the aforementioned two repetitions.

Fig. 3 is a schematic diagram of an example of SP-CSI reporting.

As shown in FIG. 3 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, the activation signaling (the DCI) instructs the terminal device to use PUSCH repetition type A to send SP-CSI through PUSCH. And, in this case, the terminal device considers that the corresponding number of repetitions is 2. In other words, PUSCH corresponds to PUSCH repetition type A.

In this example, PUSCH#1 is the first PUSCH used to carry the corresponding SP-CSI after the DCI. Since the DCI directly indicates PUSCH #1, PUSCH #1 can be considered to be scheduled by the DCI. In addition, in this example, Rep#1 and/or Rep#2 of the PUSCH (PUSCH#1) scheduled by the DCI includes/multiplexes UCI other than the SP-CSI triggered by the activation signaling, and the terminal device ignores/does not Send Rep#2; in other words, Rep#1 and Rep#2 of PUSCH#1 contain different UCI content, then the terminal device ignores/does not send Rep#2. Rep#2 can be considered a later repeat among Rep#1 and Rep#2.

In the above embodiments, the terminal device determines the corresponding PUSCH transmission mode according to the specific conditions of each PUSCH carrying SP-CSI. For the first PUSCH (PUSCH#1) scheduled after SP-CSI reporting is activated, due to the limitation of the encoding method, when the UCIs corresponding to the two repetitions (Rep#1 and Rep#2) are different, Rep The information carried on #1 and Rep#2 cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-SCI in a multi-TRP PUSCH manner (that is, using two repetitions) becomes smaller. In this case, the terminal device only sends the first repetition (Rep#1), and releases the resources corresponding to the second repetition (Rep#2) to other uplink transmissions, which is beneficial to improve the resource utilization of the system, and also The robustness of uplink SP-CSI transmission can be guaranteed.

In some embodiments, if the aforementioned PUSCH is not scheduled by the aforementioned indication information, that is, the aforementioned PUSCH has no corresponding PDCCH, the terminal device may ignore or not send the aforementioned two repetitions.

Fig. 4 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 4 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH #2 and the PUSCH sent according to the configured period (periodicity) after PUSCH #2) that does not have a corresponding PDCCH after the activation signaling (the DCI) is activated, taking PUSCH #2 as an example, Rep#1 and/or Rep#2 of PUSCH#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or, Rep#1 and Rep#2 of PUSCH#2 contain different UCI content, Then the terminal device ignores/does not send Rep#1 and Rep#2. Rep#2 can be considered a later repeat among Rep#1 and Rep#2.

In the foregoing embodiments, the terminal device determines the corresponding PUSCH transmission manner according to the specific conditions of each PUSCH carrying SP-CSI. For the second and subsequent PUSCHs after SP-CSI reporting is activated, due to the limitation of the encoding method, when the UCIs corresponding to the two repetitions (Rep#1 and Rep#2) are different, Rep#1 and Rep#2 The information carried on #2 cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, for some URLLC services, the reliability of the PUSCH cannot be guaranteed, that is, the transmission is unnecessary. Therefore, releasing the resources corresponding to Rep#1 and Rep#2 to other uplink transmissions is beneficial to improving the resource utilization rate of the system, and can also ensure the robustness of uplink SP-CSI transmission.

In some embodiments, if the aforementioned PUSCH is not scheduled by the aforementioned indication information, that is, the aforementioned PUSCH has no corresponding PDCCH, the terminal device may also ignore or not send the second of the aforementioned two repetitions.

Fig. 5 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 5 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH #2 and the PUSCH sent according to the configured period (periodicity) after PUSCH #2) that does not have a corresponding PDCCH after the activation signaling (the DCI) is activated, taking PUSCH #2 as an example, Rep#1 and/or Rep#2 of PUSCH#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or, Rep#1 and Rep#2 of PUSCH#2 contain different UCI content, Then the terminal device ignores/does not send Rep#2. Rep#2 can be considered a later repeat among Rep#1 and Rep#2.

In the foregoing embodiments, the terminal device determines the corresponding PUSCH transmission manner according to the specific conditions of each PUSCH carrying SP-CSI. For the second and subsequent PUSCHs after SP-CSI reporting is activated, due to the limitation of the encoding method, when the UCIs corresponding to the two repetitions (Rep#1 and Rep#2) are different, Rep#1 and Rep#2 The information carried on #2 cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resources corresponding to the second repetition (Rep#2) to other uplink transmissions is beneficial to improve the resource utilization rate of the system, and can also ensure the robustness of uplink SP-CSI transmission.

In the above embodiment, the terminal device may also decide whether to ignore the first repetition of the above two repetitions according to a predetermined condition.

The predetermined condition is, for example, at least one of the following conditions: a condition related to a terminal equipment process (UE procedure for reporting control information) related to reporting control information; a condition related to slot configuration (slot configuration); a cancellation indication (cancellatin indication), etc., for details, please refer to the relevant description of the current standard, and the description is omitted here.

In the above embodiment, since the PUSCH does not have a corresponding PDCCH, it means that the network device has reserved a resource for semi-persistent uplink transmission for the first repetition, but this resource may be preempted by other uplink transmissions. Therefore, the terminal device needs to determine whether the first repetition can be sent according to the above conditions. In this way, more flexible uplink scheduling can be realized and the utilization rate of system resources can be improved.

In the embodiment of the present application, the terminal device is configured with two SRS resource groups for sending PUSCH on the corresponding BWP (bandwith part, bandwidth part), which respectively correspond to two repetitions of PUSCH.

In the above embodiments, the conditions for sending multiple TRP PUSCHs are stipulated, that is, when the terminal device is configured with two SRS resource groups for PUSCH transmission, the terminal device believes that SP-CSI is carried by multiple TRP PUSCHs, that is That is, the PUSCH carrying SP-CSI corresponds to two repetitions. In addition, when the terminal device is configured with only one SRS resource group for PUSCH transmission, the PUSCH carrying SP-CSI corresponds to one repetition (single TRP PUSCH). In this way, the network device can implicitly indicate whether the PUSCH is sent through a single TRP PUSCH or multiple TRP PUSCHs by configuring one or two SRS resource groups. In this way, more flexible uplink scheduling can be realized and system performance can be improved.

In some embodiments, the above indication information is Downlink Control Information (DCI), the DCI includes a dynamic switching field (dynamic switching field), the dynamic switching field instructs the terminal device to The resource sends PUSCH.

In the above embodiments, the conditions for sending multiple TRP PUSCHs are further specified, especially considering the situation of dynamically switching domains. That is to say, when the terminal device is configured with two SRS resource groups for PUSCH transmission, and the dynamic switching field indicates multi-TRP PUSCH transmission (indicating that the terminal device selects the SRS resources according to the above two SRS resource groups respectively) Send PUSCH), the terminal device thinks that SP-CSI is carried by multiple TRP PUSCHs, that is, the PUSCH carrying SP-CSI corresponds to two repetitions. In addition, when the terminal device is configured with two SRS resource groups for PUSCH transmission, but the dynamic switching field indicates single TRP PUSCH transmission (indicating that the terminal device is selected according to one of the above two SRS resource groups) SRS resources send PUSCH), the terminal device thinks that SP-CSI is carried by a single TRP PUSCH, that is, the PUSCH carrying SP-CSI corresponds to one repetition. In this way, the network device can dynamically switch domains in DCI to dynamically indicate whether SP-CSI is sent through a single TRP PUSCH or multiple TRP PUSCHs when two SRS resource groups are configured. In this way, more flexible uplink scheduling can be realized and system performance can be improved without reconfiguration.

In the above embodiment, the DCI may not include the above dynamic switching field.

In the foregoing embodiment, the indication information is DCI as an example, but the present application is not limited thereto, and the indication information may also be other signaling sent by the network device to the terminal device.

The above only describes the steps or processes related to the present application, but the present application is not limited thereto. The method in the embodiment of the present application may also include other steps or processes. For the specific content of these steps or processes, you can refer to related technologies.

The above embodiments are only illustrative examples of the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications can also be made on the basis of the above various embodiments. For example, each of the above-mentioned embodiments may be used alone, or one or more of the above-mentioned embodiments may be combined.

According to the method of the embodiment of the present application, the transmission mode of the corresponding PUSCH is determined according to the specific situation of each PUSCH carrying SP-CSI, which improves the resource utilization rate of the system.

Embodiments of the second aspect

FIG. 6 is a schematic diagram of a method for reporting semi-persistent channel state information (SP-CSI) according to an embodiment of the present application. As shown in FIG. 6, the method includes:

601. The terminal device receives indication information; the indication information is used to activate SP-CSI report on PUSCH (SP-CSI report on PUSCH); wherein, the PUSCH corresponds to PUSCH repetition type B; the PUSCH corresponds to two nominal repetition (nominal repetition);

602. The terminal device ignores or does not send at least one of the two nominal repetitions when the PUSCH meets at least one of the following conditions, where the conditions include:

The two nominal repetitions of the PUSCH contain/correspond to different UCI contents; and

According to the embodiment of this application, when at least one of the two nominal repetitions multiplexes UCI other than SP-CSI, or when the two nominal repetitions contain/correspond to different UCI content, or the two PUSCH When at least one of the nominal repetitions is different from the corresponding actual repetition (actual repetition), when the network device receives the corresponding uplink signals of the two nominal repetitions, due to the limitation of channel coding, these uplink signals cannot be combined. This will lead to a decrease in reception performance on the network side. Therefore, the terminal device "includes or multiplexes other UCI in at least one of the two repetitions of the PUSCH", and/or, "the two repetitions of the PUSCH contain or correspond to different UCI contents", and/or "the PUSCH's When at least one of the two nominal repetitions differs from the corresponding actual repetition", at least one of the two repetitions is ignored or not sent. Thus, it is possible to avoid sending SP-CSI through multiple TRP PUSCHs when the above conditions are satisfied, and enhance the robustness of sending uplink SP-CSI. In addition, the corresponding PUSCH transmission mode is determined according to the specific conditions of each PUSCH carrying SP-CSI, which avoids unnecessary uplink transmission and improves system resource utilization.

In some embodiments, if the aforementioned PUSCH is scheduled by the aforementioned indication information, the terminal device ignores or does not send the second nominal repetition of the two nominal repetitions.

Fig. 7 is a schematic diagram of an example of SP-CSI reporting.

As shown in FIG. 7 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, the activation signaling (the DCI) instructs the terminal device to use PUSCH repetition type B to send SP-CSI through PUSCH. And, in this case, the terminal device considers that the corresponding number of repetitions is 2. In other words, PUSCH corresponds to PUSCH repetition type B.

In this example, PUSCH#1 is the first PUSCH used to carry the corresponding SP-CSI after the DCI. Since the DCI directly indicates PUSCH #1, PUSCH #1 can be considered to be scheduled by the DCI. In addition, in this example, the first nominal repetition (Rep#1) of the PUSCH (PUSCH#1) scheduled by the DCI is the same as the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 #1) is the same as its corresponding actual repetition; the second nominal repetition (Rep#2) of PUSCH#1 is different from the second actual repetition, or in other words, the second nominal repetition (Rep#2) of PUSCH#1 is different from the second nominal repetition (Rep#2) of PUSCH#1 The corresponding actual repetition is different, and the terminal device ignores/does not send Rep#2. Rep#2 can be considered a later repeat among Rep#1 and Rep#2.

In the foregoing embodiments, the terminal device determines the corresponding PUSCH transmission manner according to the specific conditions of each PUSCH carrying SP-CSI. For the first PUSCH (PUSCH#1) scheduled after SP-CSI reporting is activated, if the second nominal repetition (Rep#2) is different from the second actual repetition, it means that Rep#1 and The actual repetition time domain length of the PUSCH corresponding to Rep#2 is different. Due to the limitation of the coding mode, when the time domain resources of the PUSCH corresponding to Rep#1 and Rep#2 are different, the information carried by Rep#1 and Rep#2 cannot be combined. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resource corresponding to Rep#2 to other uplink transmission is beneficial to improve the resource utilization rate of the system.

Fig. 8 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 8 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH#1) scheduled by the activation signaling (the DCI), the first nominal repetition (Rep#1) of PUSCH#1 is different from the first actual repetition, or, PUSCH# The first nominal repetition (Rep#1) of 1 is different from its corresponding actual repetition. The terminal device regards this as an error event, and the terminal device does not have to respond to this event.

In the above embodiment, the terminal device considers the above situation to be an error event, because, for the first PUSCH (PUSCH#1) scheduled after the SP-CSI report is activated, the PUSCH#1 is the first PUSCH sent by the network device The corresponding SP-CSI activation signaling is directly scheduled, so the network device generally only schedules when the first nominal repetition (rep#1) of PUSCH#1 is the same as the first actual repetition, otherwise the network device will not will do this scheduling. Therefore, the network device generally does not perform the indication shown in FIG. 8 .

FIG. 9 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 9 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH#1) scheduled by the activation signaling (the DCI), Rep#1 and/or Rep#2 of PUSCH#1 include/multiplex the SP-CSI triggered by the activation signaling In other words, Rep#1 and Rep#2 of PUSCH#1 contain different UCI content, then the terminal device ignores/does not send Rep#2.

In the above embodiment, due to the limitation of the encoding method, when the corresponding UCIs of the PUSCHs corresponding to Rep#1 and Rep#2 are different, the information carried by Rep#1 and Rep#2 cannot be combined. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resource corresponding to Rep#2 to other uplink transmission is beneficial to improve the resource utilization rate of the system.

In addition, the situation in Figure 7 and Figure 9 can be considered together, for example, the two nominal repetitions of PUSCH satisfy the conditions corresponding to Figure 7 (Rep #2 of PUSCH #1 is split) and the conditions corresponding to Figure 9 (PUSCH #1 Rep#1 and/or Rep#2 multiplexed at least one of UCIs other than SP-SCI), the terminal device ignores/does not send the second nominal repetition (Rep#2). Due to the limitation of the encoding method, when the time domain resources corresponding to Rep#1 and Rep#2 are different (segmentation occurs) and/or the UCIs corresponding to Rep#1 and Rep#2 are different, the information on Rep#1 and Rep#2 Bearer information cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two nominal repetitions) becomes smaller. In this case, releasing the resource corresponding to Rep#2 to other uplink transmission is beneficial to improve the resource utilization rate of the system.

In some embodiments, if the above PUSCH has no corresponding PDCCH, the terminal device ignores or does not send the two nominal repetitions.

Fig. 10 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 10 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH #2 and the PUSCH sent according to the configured period (periodicity) after PUSCH #2) that does not have a corresponding PDCCH after the activation signaling (the DCI) is activated, taking PUSCH #2 as an example, The first nominal repetition (Rep#1) of PUSCH#2 is the same as the first actual repetition, in other words, the first nominal repetition (Rep#1) of PUSCH#2 is the same as its corresponding actual repetition; The second nominal repetition (Rep#2) is different from the second actual repetition, or the second nominal repetition (Rep#2) of PUSCH#2 is different from the corresponding actual repetition, then the terminal device ignores/does not send Rep #1 and Rep#2. Rep#2 can be considered a later repeat among Rep#1 and Rep#2.

In the foregoing embodiments, the terminal device determines the corresponding PUSCH transmission manner according to the specific conditions of each PUSCH carrying SP-CSI. For the second and subsequent PUSCH after SP-CSI reporting is activated, if the second nominal repetition (Rep#2) is different from its corresponding actual repetition, it means that Rep#1 and Rep#2 correspond The actual repetition time domain length of PUSCH is different. Due to the limitation of the coding mode, when the time domain resources of the PUSCH corresponding to Rep#1 and Rep#2 are different, the information carried by Rep#1 and Rep#2 cannot be combined. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, for some URLLC services, the reliability of the PUSCH cannot be guaranteed, that is, the transmission is unnecessary. Therefore, all the resources corresponding to Rep#1 and Rep#2 are released for other uplink transmissions, which is beneficial to improve the resource utilization rate of the system.

Fig. 11 is a schematic diagram of another example of SP-CSI reporting.

As shown in Figure 11, different from Figure 10, the first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#2 1) It is different from its corresponding actual repetition; the second nominal repetition (Rep#2) of PUSCH#2 is the same as the second actual repetition, or in other words, the second nominal repetition (Rep#2) of PUSCH#2 corresponds to it The actual repetition is the same, the terminal device ignores/does not send Rep#1 and Rep#2.

In addition, similar to the example in FIG. 10 , releasing the resources corresponding to Rep#1 and Rep#2 for other uplink transmissions is beneficial to improve the resource utilization of the system.

Fig. 12 is a schematic diagram of another example of SP-CSI reporting.

As shown in Figure 12, unlike Figure 10 and Figure 11, the first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, or the first nominal repetition of PUSCH#2 (Rep#1) is different from its corresponding actual repetition; the second nominal repetition (Rep#2) of PUSCH#2 is different from the second actual repetition, or in other words, the second nominal repetition of PUSCH#2 (Rep#2 ) is different from its corresponding actual repetition, the terminal device ignores/does not send Rep#1 and Rep#2.

Fig. 13 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 13 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH #2 and the PUSCH sent according to the configured period (periodicity) after PUSCH #2) that does not have a corresponding PDCCH after the activation signaling (the DCI) is activated, taking PUSCH #2 as an example, The first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, in other words, the first nominal repetition (Rep#1) of PUSCH#2 is different from its corresponding actual repetition; The second nominal repetition (Rep#2) is the same as the second actual repetition, in other words, the second nominal repetition (Rep#2) of PUSCH#2 is the same as its corresponding actual repetition; and, the Rep# of PUSCH#2 1 and/or Rep#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or, Rep#1 and Rep#2 of PUSCH#1 contain different UCI content, then the terminal device ignores/does not Send Rep#1 and Rep#2.

In the above embodiment, for the second and subsequent PUSCHs after SP-CSI reporting is activated, due to the limitation of the encoding method, when the time domain resources of the PUSCHs corresponding to Rep#1 and Rep#2 are different or correspond to When the UCIs are different, the information carried by Rep#1 and Rep#2 cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, for some URLLC services, the reliability of the PUSCH cannot be guaranteed, that is, the transmission is unnecessary. Therefore, all the resources corresponding to Rep#1 and Rep#2 are released for other uplink transmissions, which is beneficial to improve the resource utilization rate of the system.

In some embodiments, if the PUSCH does not have a corresponding PDCCH, the terminal device ignores or does not send the second nominal repetition among the two nominal repetitions.

Fig. 14 is a schematic diagram of an example of SP-CSI reporting.

As shown in FIG. 14 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH (PUSCH #2 and the PUSCH sent according to the configured period (periodicity) after PUSCH #2) that does not have a corresponding PDCCH after the activation signaling (the DCI) is activated, taking PUSCH #2 as an example, The first nominal repetition (Rep#1) of PUSCH#2 is the same as the first actual repetition, in other words, the first nominal repetition (Rep#1) of PUSCH#1 is the same as its corresponding actual repetition; The second nominal repetition (Rep#2) is different from the second actual repetition, or the second nominal repetition (Rep#2) of PUSCH#1 is different from its corresponding actual repetition, then the terminal device ignores/does not send Rep #2.

In the foregoing embodiments, the terminal device determines the corresponding PUSCH transmission manner according to the specific conditions of each PUSCH carrying SP-CSI. For the second and subsequent PUSCH after SP-CSI reporting is activated, if the second nominal repetition (Rep#2) is different from its corresponding actual repetition, it means that Rep#1 and Rep#2 correspond The actual repetition time domain length of PUSCH is different. Due to the limitation of the coding mode, when the time domain resources of the PUSCH corresponding to Rep#1 and Rep#2 are different, the information carried by Rep#1 and Rep#2 cannot be combined. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resource corresponding to Rep#2 to other uplink transmission is beneficial to improve the resource utilization rate of the system.

Fig. 15 is a schematic diagram of another example of SP-CSI reporting.

As shown in FIG. 15 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, for the PUSCH without corresponding PDCCH (PUSCH #2 and the PUSCH sent after PUSCH #2 according to the configured periodicity) after the activation of the activation signaling, taking PUSCH #2 as an example, the PUSCH #2 Rep#1 and/or Rep#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or, Rep#1 and Rep#2 of PUSCH#2 contain different UCI content, then the terminal device ignores /Do not send Rep#2.

In the foregoing embodiments, the terminal device determines the corresponding PUSCH transmission manner according to the specific conditions of each PUSCH carrying SP-CSI. For the second and subsequent PUSCH after SP-CSI reporting is activated, due to the limitation of the encoding method, when the UCIs corresponding to Rep#1 and Rep#2 are different, the information carried on Rep#1 and Rep#2 could not be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resource corresponding to Rep#2 to other uplink transmission is beneficial to improve the resource utilization rate of the system.

In addition, the conditions in Figure 14 and Figure 15 can be considered in combination, for example, when the conditions corresponding to Figure 14 (Rep#2 of PUSCH#2 is split) and the conditions corresponding to Figure 15 (Rep#2 of PUSCH#2 occurs and Rep#1 and/or Rep#2 are multiplexed with UCI other than SP-CSI) satisfying at least one of them, the terminal device ignores/does not send Rep#2. For the second and subsequent PUSCH after SP-CSI reporting is activated, due to the limitation of the encoding method, when the UCIs corresponding to Rep#1 and Rep#2 are different, the time domain resources are different, and/or Rep#1 When the UCI corresponding to Rep#2 is different, the information carried by Rep#1 and Rep#2 cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resources corresponding to Rep#2 to other uplink transmissions is beneficial to improve the resource utilization of the system.

In the above embodiment, the terminal device may also decide whether to ignore the first nominal repetition among the above two nominal repetitions according to a predetermined condition.

The predetermined condition is, for example, at least one of the following conditions: a condition related to the UE procedure for reporting control information related to reporting control information, a condition related to slot configuration (slot configuration), and a cancellation indication (cancellatin indication) Relevant conditions, etc., can refer to the relevant description of the current standard for details, and the description is omitted here.

In the above embodiment, since the PUSCH does not have a corresponding PDCCH, it means that the network device has reserved a semi-persistent uplink transmission resource for the first nominal repetition, but this resource may be preempted by other uplink transmissions. Therefore, the terminal device needs to determine whether the first nominal repetition can be sent according to the above conditions. In this way, more flexible uplink scheduling can be realized and the utilization rate of system resources can be improved.

In some embodiments, if the PUSCH does not have a corresponding PDCCH, and at least one of the nominal repetitions of the PUSCH is different from the corresponding actual repetition, the terminal device ignores or does not send the nominal repetition different from the corresponding actual repetition.

As shown in Figure 14, the second nominal repetition (Rep#2) of PUSCH#2 is different from the second actual repetition, or in other words, the second nominal repetition (Rep#2) of PUSCH#2 and its corresponding actual repetition different, the terminal device ignores/does not send Rep#2.

Fig. 16 is a schematic diagram of another example of SP-CSI reporting.

As shown in Figure 16, the first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 and its corresponding actual repetition different, the terminal device ignores/does not send Rep#1.

In the above embodiment, the resource corresponding to the nominal repetition different from the corresponding actual repetition is released to other uplink transmission, which is beneficial to improve the resource utilization rate of the system.

Fig. 17 is a schematic diagram of another example of SP-CSI reporting.

As shown in Figure 17, the first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 and its corresponding actual repetition different, the terminal device ignores/does not send Rep#1.

In the example in FIG. 17 , different from the example in FIG. 16 , Rep#1 and/or Rep#2 of PUSCH#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or in other words, PUSCH Rep#1 and Rep#2 of #2 contain different UCI content.

In the above embodiment, for the second and subsequent PUSCHs after SP-CSI reporting is activated, when the nominal repetition of the PUSCH carrying SP-CSI is different from the corresponding actual repetition, due to this situation, activation The code rate indicated by the information does not match the code rate when the actual PUSCH is sent. Therefore, the end device does not send nominal repetitions that differ from the corresponding actual repetitions. In this case, releasing the resources corresponding to the nominal repetition to other uplink transmissions is beneficial to improve the resource utilization rate of the system.

In the above embodiments, such as the examples shown in FIG. 16 and FIG. 17 , the terminal device may also decide whether to ignore the nominal repetition that is the same as the corresponding actual repetition among the above two nominal repetitions according to a predetermined condition.

The predetermined conditions have been described above and are omitted here. In this way, more flexible uplink scheduling can be realized and system performance can be improved.

In some embodiments, if the above-mentioned PUSCH does not correspond to a PDCCH, and the two nominal repetitions of the PUSCH are the same as the corresponding actual repetitions, and at least one of the two nominal repetitions of the PUSCH includes or multiplexes If there is no other uplink control information (UCI) other than the above SP-CSI, the terminal device ignores or does not send the second nominal repetition in the two nominal repetitions.

As shown in Figure 15, the first nominal repetition (Rep#1) of PUSCH#2 is the same as the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 and its corresponding actual repetition The same; the second nominal repetition (Rep#2) of PUSCH#2 is the same as the second actual repetition, or the second nominal repetition (Rep#2) of PUSCH#1 is the same as its corresponding actual repetition; the other In one aspect, Rep#1 and/or Rep#2 of PUSCH#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or in other words, Rep#1 and Rep#2 of PUSCH#2 contain different UCI content, the terminal device ignores/does not send Rep#2.

In the above embodiment, the resource corresponding to Rep#2 is released for other uplink transmission, which is beneficial to improve the resource utilization rate of the system.

In some embodiments, the terminal device first checks whether at least one of the two nominal repetitions of the PUSCH is the same as the corresponding actual repetition, and then according to whether at least one of the two nominal repetitions of the PUSCH includes or multiplexes For other uplink control information (UCI) except the SP-CSI, determine whether to ignore or not send the nominal repetition.

As shown in Figure 13, since the first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 and its corresponding actual If the repetition is different, the terminal device ignores/does not send Rep#1 and Rep#2 regardless of whether the two nominal repetitions of PUSCH#2 include/multiplex other UCI. Therefore, as mentioned above, all the resources corresponding to Rep#1 and Rep#2 are released for other uplink transmissions, which is beneficial to improve the resource utilization rate of the system.

As shown in Figure 17, similar to the example in Figure 13, since the first nominal repetition (Rep#1) of PUSCH#2 is different from the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 (Rep #1) Different from its corresponding actual repetition, the terminal device does not consider whether the two nominal repetitions of PUSCH#2 include/multiplex other UCIs, but ignores/does not send Rep#1. Therefore, Rep#2 is not affected by the conditions related to UCI, and can continue to be used to bear SP-CSI, increasing the transmission opportunity; and, as mentioned above, the resources corresponding to Rep#1 are released for other uplink transmissions , which is conducive to improving the resource utilization of the system.

As shown in Figure 15, the first nominal repetition (Rep#1) of PUSCH#2 is the same as the first actual repetition, or in other words, the first nominal repetition (Rep#1) of PUSCH#1 and its corresponding actual repetition The same; the second nominal repetition (Rep#2) of PUSCH#2 is the same as the second actual repetition, or the second nominal repetition (Rep#2) of PUSCH#1 is the same as its corresponding actual repetition; the other In one aspect, Rep#1 and/or Rep#2 of PUSCH#2 include/multiplex UCI other than SP-CSI triggered by activation signaling, or in other words, Rep#1 and Rep#2 of PUSCH#2 contain different UCI content. In this case, the terminal device first determines whether to send/ignore Rep#1 and/or Rep#2 according to whether Rep#1 and/or Rep#2 corresponding to PUSCH#2 is the same as the corresponding actual repetition. That is, both Rep#1 and Rep#2 corresponding to PUSCH#2 are the same as the corresponding actual repetitions, and the terminal device does not ignore Rep#1 and Rep#2. After considering the conditions related to whether the nominal repetition and actual repetition are the same, the terminal device needs to continue to consider the multiplexing of UCI on Rep#1 and Rep#2. In this example, Rep#1 and/or Rep#2 include/multiplex other UCIs other than the activated SP-CSI, or, the content of UCI corresponding to Rep#1 and Rep#2 is different, then the terminal device ignores/does not Send Rep#2.

Embodiments of the third aspect

The present application also provides a method for reporting semi-persistent channel state information (SP-CSI), which is described from the terminal equipment side.

FIG. 18 is a schematic diagram of a method for reporting semi-persistent channel state information (SP-CSI) according to an embodiment of the present application. As shown in FIG. 18, the method includes:

1801. The terminal device receives indication information; the indication information is used to activate SP-CSI report on PUSCH (SP-CSI report on PUSCH); wherein, the PUSCH corresponds to PUSCH repetition type A;

1802. The terminal device performs at least one of the following first behaviors when the first PUSCH scheduled by the indication information in the PUSCH satisfies at least one of the following first conditions.

This first condition includes:

At least one of the two repetitions (repetitions) of the first PUSCH includes or multiplexes other uplink control information (UCI) except the SP-CSI; and

This first behavior includes:

at least ignoring or not sending a second of two repetitions of a PUSCH (second PUSCH) that has no corresponding PDCCH in said PUSCH;

Think (assumes) that the number of repetitions of the PUSCH is 1;

assumes that the number of repetitions of the first PUSCH is 1; and

The number of repetitions of a PUSCH (second PUSCH) that has no corresponding PDCCH among the PUSCHs is assumed to be 1.

According to the method provided in the embodiment of the present application, it is possible to avoid sending SP-CSI through multiple TRP PUSCHs when the above first condition is satisfied, and enhance the robustness of sending uplink SP-CSI. In addition, the terminal device can determine the corresponding PUSCH transmission mode according to the specific situation of the first PUSCH carrying SP-CSI, which avoids unnecessary uplink transmission, and is conducive to simplifying the design complexity of the terminal and saving costs.

Fig. 19 is a schematic diagram of an example of SP-CSI reporting.

As shown in FIG. 19 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by the PUSCH and the PUSCH does not include a transport block (Transport block, TB).

In this example, the activation signaling (the DCI) instructs the terminal device to use PUSCH repetition type A to send SP-CSI through PUSCH. In other words, the PUSCH corresponds to PUSCH repetition type A.

In this example, PUSCH#1 is the first PUSCH used to carry the corresponding SP-CSI after the DCI. Since the DCI directly indicates PUSCH #1, PUSCH #1 can be considered to be scheduled by the DCI. In addition, in this example, for the PUSCH scheduled by the DCI (PUSCH#1, referred to as the first PUSCH), if Rep#1 and/or Rep#2 of PUSCH#1 include/multiplex the SP triggered by the activation signaling - UCI other than CSI, or if Rep#1 and Rep#2 of PUSCH#1 contain different UCI content, the terminal device ignores/does not send Rep#2. In this case, the terminal device considers that the number of repetitions corresponding to the first PUSCH is 1.

In this example, for the PUSCH without corresponding PDCCH (PUSCH#2 and the PUSCH after PUSCH#2, referred to as the second PUSCH) after the DCI is activated, the number of repetitions to be sent is determined according to the actual sending situation of PUSCH#1. That is to say, if PUSCH#1 only considers sending Rep#1 (ignoring/not sending Rep#2), PUSCH#2 and subsequent PUSCHs (second PUSCH) only consider sending corresponding Rep#1 (ignoring/not sending Corresponding Rep#2). In other words, the terminal device considers that the number of repetitions corresponding to the second PUSCH is 1.

From another perspective, if Rep#1 and/or Rep#2 of PUSCH#1 include/multiplex UCI other than SP-CSI triggered by activation signaling, or in other words, Rep#1 and Rep# of PUSCH#1 2 contains different UCI content, the terminal device ignores/does not send Rep#2 of the PUSCH carrying the SP-CSI. In other words, the terminal device considers that the number of repetitions corresponding to the PUSCH is 1.

In the above embodiment, the terminal device determines the corresponding PUSCH transmission mode according to the specific conditions of the first PUSCH carrying SP-CSI. It is beneficial to simplify the design complexity of the terminal and save costs.

In addition, for the first PUSCH (PUSCH#1) scheduled after SP-CSI reporting is activated, due to the limitation of the encoding method, when the UCIs corresponding to the two repetitions (Rep#1 and Rep#2) are different , the information carried on Rep#1 and Rep#2 cannot be merged. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-SCI in a multi-TRP PUSCH manner (that is, using two repetitions) becomes smaller. In this case, the terminal device only sends the first repetition (Rep#1), and releases the resources corresponding to the second repetition (Rep#2) to other uplink transmissions, which is beneficial to improve the resource utilization of the system, and also The robustness of uplink SP-CSI transmission can be guaranteed.

In the above embodiments, the conditions for sending multiple TRP PUSCHs are further specified, especially considering the situation of dynamically switching domains. That is to say, when the terminal device is configured with two SRS resource groups for PUSCH transmission, and the dynamic switching field indicates multi-TRP PUSCH transmission (indicating that the terminal device selects the SRS resources according to the above two SRS resource groups respectively) Send PUSCH), the terminal device thinks that SP-CSI is carried by multiple TRP PUSCHs, that is, the PUSCH carrying SP-CSI corresponds to two repetitions. In addition, when the terminal device is configured with two SRS resource groups for PUSCH transmission, but the dynamic switching field indicates single TRP PUSCH transmission (indicating that the terminal device is selected according to one of the above two SRS resource groups) SRS resources send PUSCH), the terminal device thinks that SP-CSI is carried by a single TRP PUSCH, that is, the PUSCH carrying SP-CSI corresponds to one repetition. In this way, the network device can dynamically switch domains in the DCI under the condition of configuring two SRS resource groups, and dynamically indicate whether the SP-CSI is sent through a single TRP PUSCH or multiple TRP PUSCHs. In this way, more flexible uplink scheduling can be realized and system performance can be improved without reconfiguration.

The above only describes the steps or processes related to the present application, but the present application is not limited thereto. The method in the embodiment of the present application may also include other steps or processes, and for the specific content of these steps or processes, reference may be made to related technologies.

According to the method of the embodiment of the present application, the terminal device determines the corresponding PUSCH transmission mode according to the specific situation of the first PUSCH carrying SP-CSI. It is beneficial to simplify the design complexity of the terminal and save costs.

Embodiments of the fourth aspect

The implementation of this application provides a method for reporting semi-persistent channel state information (SP-CSI), which is described from the side of a terminal device.

FIG. 20 is a schematic diagram of a method for reporting semi-persistent channel state information (SP-CSI) according to an embodiment of the present application. As shown in FIG. 20, the method includes:

2001, the terminal device receives indication information; the indication information is used to activate SP-CSI report on PUSCH (SP-CSI report on PUSCH); wherein, the PUSCH corresponds to PUSCH repetition type B;

2002. The terminal device executes at least one of the following second behaviors when the first PUSCH scheduled by the indication information in the PUSCH satisfies at least one of the following second conditions.

This second condition includes:

The two nominal repetitions of the first PUSCH contain/correspond to different UCI contents; and

This second behavior includes:

at least ignoring or not sending the second of the two nominal repetitions of a PUSCH without a corresponding PDCCH in said PUSCH (the second PUSCH);

think (assumes) the nominal number of repetitions of the PUSCH is 1;

think (assumes) that the nominal number of repetitions of the first PUSCH is 1;

The nominal number of repetitions of a PUSCH (second PUSCH) without a corresponding PDCCH among the PUSCHs is assumed to be 1.

According to the method provided in the embodiment of the present application, it is possible to avoid sending SP-CSI through multiple TRP PUSCHs when the above second condition is satisfied, and enhance the robustness of sending uplink SP-CSI. In addition, the terminal device can determine the corresponding PUSCH transmission mode according to the specific situation of the first PUSCH carrying SP-CSI, which avoids unnecessary uplink transmission, and is conducive to simplifying the design complexity of the terminal and saving costs.

Fig. 21 is a schematic diagram of an example of SP-CSI reporting.

As shown in FIG. 21 , the terminal device receives an activation signaling (from the network device), which is DCI scrambled by SP-CSI-RNTI. The terminal device triggers SP-CSI reporting according to the indication of the CSI request (CSI request) field in the DCI. The SP-CSI is sent by PUSCH (the first PUSCH and the second PUSCH) and the PUSCH does not include a transport block (Transport block, TB).

In this example, the activation signaling (the DCI) instructs the terminal device to use PUSCH repetition type B to send SP-CSI through PUSCH. In other words, PUSCH corresponds to PUSCH repetition type B.

In this example, PUSCH#1 is the first PUSCH used to carry the corresponding SP-CSI after the DCI. Since the DCI directly indicates PUSCH #1, PUSCH #1 can be considered to be scheduled by the DCI. In addition, in this example, for the PUSCH scheduled by the DCI (PUSCH#1, called the first PUSCH), the second nominal repetition (Rep#2) of PUSCH#1 is different from its corresponding actual repetition, and the terminal device ignores /Do not send Rep#2. In other words, the terminal device considers that the number of repetitions corresponding to the first PUSCH is 1.

In addition, in this example, if the UCI content contained or corresponding to the two nominal repetitions (Rep#1 and Rep#2) is different, or at least one of the two nominal repetitions contains or reuses content other than For UCI other than SP-CSI, the terminal device ignores/does not send Rep#2. In other words, the terminal device considers that the number of repetitions corresponding to the first PUSCH is 1.

The above described the embodiment of the application by taking each condition in the second condition as an example, and the application is not limited thereto. The conditions in the second condition above can be combined arbitrarily, and if one of the conditions in the second condition is satisfied, then The end device ignores/does not send Rep#2. In other words, the terminal device considers that the number of repetitions corresponding to the first PUSCH is 1.

In this example, for the PUSCH that does not have a corresponding PDCCH (PUSCH#2 and the PUSCH after PUSCH#2, called the second PUSCH) after the activation of the activation signaling, the repetition that needs to be sent is determined according to the actual transmission situation of PUSCH#1 frequency. That is to say, if PUSCH#1 only considers sending Rep#1 (ignoring/not sending Rep#2), PUSCH#2 and subsequent PUSCHs (second PUSCH) only consider sending corresponding Rep#1 (ignoring/not sending Corresponding Rep#2). In other words, the terminal device considers that the number of repetitions corresponding to the second PUSCH is 1.

From another point of view, if Rep#2 of PUSCH#1 is different from its corresponding actual repetition, or Rep#1 and Rep#2 of PUSCH#1 contain or correspond to different UCI content, or Rep#1 of PUSCH#1 If at least one of Rep#2 and Rep#2 contains or multiplexes UCI other than SP-CSI, the terminal device ignores/does not send Rep#2 of the PUSCH carrying the SP-CSI. In other words, the terminal device considers that the number of repetitions corresponding to the PUSCH is 1.

In addition, for the first PUSCH (PUSCH#1, the first PUSCH) scheduled after SP-CSI reporting is activated, if the second nominal repetition (Rep#2) is different from the second actual repetition, it means That is, the actual repetition time domain lengths of the PUSCH corresponding to Rep#1 and Rep#2 are different. Due to the limitation of the coding mode, when the time domain resources of the PUSCH corresponding to Rep#1 and Rep#2 are different, the information carried by Rep#1 and Rep#2 cannot be combined. Therefore, the diversity gain of Rep#1 and Rep#2 decreases, which means that the gain of sending SP-CSI in multi-TRP PUSCH mode (using two repetitions) becomes smaller. In this case, releasing the resource corresponding to Rep#2 to other uplink transmission is beneficial to improve the resource utilization rate of the system.
