[0043] The transmission processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0044] like Figure 2 As shown in the figure, an embodiment of this application provides a power control parameter indication method, including:

[0045] Step 201: The terminal receives downlink control information;

[0046] Step 202: The terminal performs power control based on the downlink control information; wherein,

[0047] The downlink control information includes at least one power control parameter indication field, which indicates a first power control parameter for different physical uplink shared channel (PUSCH) transmission timings, the PUSCH transmission timings being associated with channel sounding reference signal (SRS) resources or SRS resource groups.

[0048] Here, the downlink control information (DCI) received by the terminal includes at least one power control parameter indication field. This power control parameter indication field indicates the first power control parameter for different PUSCH transmission timings, and the PUSCH transmission timing is associated with an SRS resource or SRS resource group. Thus, combining the correspondence between TRPs and SRS resources or SRS resource groups (i.e., each TRP has a corresponding SRS resource or SRS resource group), when facing multiple TRPs, the DCI including at least one power control parameter indication field can indicate the first power control parameter for the PUSCH transmission timing of multiple TRPs, thereby satisfying the transmission requirements of multiple TRPs.

[0049] Here, an SRS resource group refers to multiple (or a set of) SRS resources. Optionally, the power control parameter indication field can also be understood as an open-loop power control parameter set indication field. Accordingly, the first power control parameter is the power control parameter P0 used to determine the transmit power. In the following embodiments, P0 can be directly used to replace the first power control parameter. Of course, other implementations of the first power control parameter can also be applied to the embodiments of this application, and will not be described in detail here.

[0050] Optionally, the SRS resources or SRS resource groups associated with the different PUSCH transmission times may be different.

[0051] It should be understood that different SRS resources or SRS resource groups are applicable to different TRPs. Therefore, when different PUSCH transmission times are associated with different SRS resources or SRS resource groups, a power control parameter indication field can indicate the first power control parameter for the PUSCH transmission time for different TRPs.

[0052] Thus, for multiple TRPs, such as TRP1, TRP2, TRP3, and TRP4, the indication of PUSCH transmission timing (P0) varies depending on the SRS resources or SRS resource groups of each TRP. In DCI, different PUSCH transmission timings (P0) can be indicated pairwise by two power control parameter indication fields. For example, power control parameter indication field 1 indicates the P0 of PUSCH transmission timings for TRP1 and TRP2, and power control parameter indication field 2 indicates the P0 of PUSCH transmission timings for TRP3 and TRP4. Of course, it is also possible to indicate the P0 of PUSCH transmission timings for TRP1, TRP2, TRP3, and TRP4 using only one power control parameter indication field.

[0053] It should also be noted that a PUSCH transmission timing can be a slot, a nominal retransmission timing, an actual retransmission timing, or multiple consecutive OFDM symbols, etc.

[0054] Optionally, in this embodiment, the downlink control information further includes an SRI field, which indicates a set of candidate parameters for the first power control parameter of the PUSCH transmission timing associated with the SRS resource or SRS resource group.

[0055] That is, the DCI may also include an SRI field, which is a set of candidate parameters for the first power control parameter used to indicate the timing of PUSCH transmission associated with an SRS resource or an SRS resource group.

[0056] Optionally, in this embodiment, among the different PUSCH transmission times, the candidate parameter set of the first power control parameter for at least one PUSCH transmission time is predefined or preconfigured.

[0057] In other words, the power control parameter indication field indicates a first power control parameter, at least one of which belongs to a predefined or preconfigured set of candidate parameters. Correspondingly, the DCI does not include any SRI fields, or includes only one SRI field.

[0058] Optionally, the candidate parameter set includes at least one of the following:

[0059] First candidate set;

[0060] Second candidate set;

[0061] Wherein, the first candidate set belongs to the first set list; the second candidate set belongs to the second set list.

[0062] Thus, the candidate parameter set for the first power control parameter can be a set belonging only to the first set list, a set belonging only to the second set list, or a set belonging to both the first set list and the second set list.

[0063] It should be noted that in this embodiment, a first set list and a second set list are set up to determine the candidate parameter set, thereby obtaining the first power control parameter. Here, each set in both the first and second set lists includes the first power control parameter. However, the first set list differs from the second set list. In addition to the first power control parameter, each set in the first set list also includes other power control parameters such as alpha, path loss reference signal, and closed-loop power adjustment index; while each set in the second set list is dedicated to the first power control parameter and does not include other power control parameters. Specifically, the first set list can be an update list sri-PUSCH-MappingToAddModList or a P0 and alpha set list p0-AlphaSets for SRI-mapped PUSCH power control parameters; the second set list can be an open-loop power control parameter set list p0-PUSCH-SetList-r16.

[0064] Of course, both the first set list and the second set list can include one or more lists. In this embodiment, the first set list and the second set list are configured or predefined by higher-layer signaling.

[0065] Optionally, the first set list and the second set list are associated with the SRS resource set, respectively.

[0066] The first set list and the second set list can be associated with the same SRS resource set or with different SRS resource sets.

[0067] Here, SRS resource sets correspond to different TRPs. For example, SRS resources or SRS resource groups in SRS resource set 1 corresponding to TRP1 are used for transmission in TRP1, while SRS resources or SRS resource groups in SRS resource set 2 corresponding to TRP2 are used for transmission in TRP2. Therefore, the first set list can be a first set list associated with SRS resource set 1, and the second set list can be a second set list associated with SRS resource set 1. Of course, the first set list and the second set list can be associated with different SRS resource sets, which will not be listed here.

[0068] An SRS resource set is configured by RRC and contains multiple SRS resources. An SRS resource group, indicated by an SRI field, is a subset of all SRS resources in the SRS resource set.

[0069] In this embodiment, the set in the first set list (i.e., the first parameter set) can be one or more, and the set in the second set list (i.e., the second parameter set) can be one or more.

[0070] Therefore, the candidate parameter set indicated by the SRI field above, by sorting order or index value, indicates a first parameter set in the first set list when the candidate parameter set is the first candidate set, such as the first first parameter set or the first parameter set with an index value of 0, or the first parameter set with the smallest index value; when the candidate parameter set is the second candidate set, it indicates a second parameter set in the second set list, such as the first second parameter set or the second parameter set with an index value of 0, or the second parameter set with the smallest index value.

[0071] The predefined or preconfigured candidate parameter set can also be arranged in order or index value. When the candidate parameter set is the first candidate set, the predefined or preconfigured candidate parameter set corresponds to the arrangement order or index value in the first set list; when the candidate parameter set is the second candidate set, the predefined or preconfigured candidate parameter set corresponds to the arrangement order or index value in the second set list.

[0072] It should be noted that in this embodiment, after the terminal receives the DCI, in order to determine the P0 of the PUSCH transmission timing, it needs to first determine the set of candidate parameters.

[0073] In cases where higher-layer signaling configurations or predefined first and second set lists are provided, in this embodiment, the determined candidate parameter set may optionally include both the first and second candidate sets. For example, if an SRS resource or SRS resource group belongs to SRS resource set 1, then for PUSCH transmission timing associated with an SRS resource or SRS resource group from SRS resource set 1, the first candidate set can be indicated by the SRI field associated with SRS resource set 1 in the DCI in the first set list, or selected based on a predefined or pre-configured first set list; the second candidate set can be indicated by the SRI field associated with SRS resource set 1 in the DCI in the second set list, or selected based on a predefined or pre-configured second set list. Then, the target parameter set is further determined from the first and second candidate sets to obtain the first power control parameter. If an SRS resource or SRS resource group belongs to SRS resource set 2, the first and second candidate sets can also be determined in the same way for PUSCH transmission timing associated with an SRS resource or SRS resource group from SRS resource set 2.

[0074] Of course, the first candidate set of the first power control parameters associated with the PUSCH transmission timing of SRS resources or SRS resource groups in SRS resource set 1 is set 1, and the first candidate set of the first power control parameters associated with the PUSCH transmission timing of SRS resources or SRS resource groups in SRS resource set 2 is set 2. The first set lists to which set 1 and set 2 belong can be the same or different.

[0075] For different PUSCH transmission opportunities associated with different SRS resources or SRS resource groups, the candidate parameter sets of P0 for these different PUSCH transmission opportunities can be different sets within the same set list. Continuing the previous example, assuming that for PUSCH transmission opportunities associated with SRS resources or SRS resource groups from SRS resource set 1, the first candidate set is the first set in the first set list, and the second candidate set is the set with the smallest index value in the second set list, then for PUSCH transmission opportunities associated with SRS resources or SRS resource groups from SRS resource set 2, the first candidate set can be indicated by the SRI field of the associated SRS resource set 2 in the DCI in the first set list, or selected based on predefined or preconfigured settings in the first set list, determining that the first candidate set at this time is the second set in the first set list; the second candidate set can be indicated by the SRI field of the associated SRS resource set 2 in the DCI in the second set list, or selected based on predefined or preconfigured settings in the second set list, determining that the second candidate set at this time is the set with the second smallest index value in the second set list.

[0076] Of course, for different PUSCH transmission times associated with different SRS resources or SRS resource groups, the candidate parameter set of P0 for these different PUSCH transmission times can also use the same set in the same set list, which will not be elaborated here.

[0077] Optionally, the power control parameter indication field has a bit size of 3 bits.

[0078] At this time, the 3-bit power control parameter indication field will specifically indicate the first power control parameters for the first PUSCH transmission timing and the first power control parameters for the second PUSCH transmission timing.

[0079] Of course, if the power control parameter indication field is to indicate the first power control parameter for PUSCH transmission timing associated with two or more different SRS resources or resource groups, the number of bits in the power control parameter indication field is M, where M can be the number of different SRS resources or resource groups plus 1, or the number of SRS resource sets used for codebook or non-codebook transmission plus 1.

[0080] In this embodiment, when the power control parameter indication field has a bit size of 3 bits, optionally, the downlink control information does not include the SRI field.

[0081] The first bit of the power control parameter indication field indicates that the first target parameter set is a target candidate set, the target candidate set belongs to the first target set list, and the first target parameter set is the target parameter set of the first power control parameter for different PUSCH transmission times.

[0082] When the second bit of the power control parameter indication field indicates that the current target candidate set indicated by the first bit belongs to the second set list, the power control parameter of the first power control parameter of the first PUSCH transmission timing in the current target candidate set is indicated by the second bit. The SRS resource or SRS resource group associated with the first PUSCH transmission timing belongs to the first SRS resource set.

[0083] When the third bit of the power control parameter indication field indicates that the current target candidate set indicated by the first bit belongs to the second set list, the power control parameter of the first power control parameter of the second PUSCH transmission timing in the current target candidate set is indicated, and the SRS resource or SRS resource group associated with the second PUSCH transmission timing belongs to the second SRS resource set.

[0084] The first target set list to which the target candidate set corresponding to the first PUSCH transmission timing belongs is the same as the first target set list to which the target candidate set corresponding to the second PUSCH transmission timing belongs.

[0085] Alternatively, the first target set list to which the target candidate set corresponding to the first PUSCH transmission timing belongs is different from the first target set list to which the target candidate set corresponding to the second PUSCH transmission timing belongs.

[0086] Here, the first target set list can be either a first set list or a second set list.

[0087] The absence of SRI fields in DCI can also be interpreted as all SRI fields in DCI being 0 bits. Because DCI does not include SRI fields, the candidate parameter sets for the first power control parameters during the first PUSCH transmission and the first power control parameters during the second PUSCH transmission are determined based on predefined or preconfigured parameters.

[0088] Since the candidate parameter set may include a first candidate set and a second candidate set, the first power control parameter needs to further determine a target candidate set from the first candidate set and the second candidate set as the target parameter set, and then determine the first power control parameter for PUSCH transmission timing from the target parameter set.

[0089] At this point, in the 3-bit power control parameter indication field, the first bit indicates that the first target parameter set is a target candidate set. This target candidate set belongs to the first target set list. Since the first target parameter set is the target parameter set of the first power control parameters for different PUSCH transmission times, that is, the first power control parameters for the first and second PUSCH transmission times indicated by the power control parameter indication field either all belong to the first set list or all belong to the second set list. For example, "0" indicates that the first target parameter set belongs to the first set list, and "1" indicates that the first target parameter set belongs to the second set list.

[0090] It should be understood that the target candidate sets of the first power control parameters for different PUSCH transmission times can be different sets within the first set list, even if they all belong to the first set list. Similarly, the target parameter sets of the first power control parameters for different PUSCH transmission times can be different sets within the second set list, even if they all belong to the second set list. That is, list 1 to which the target candidate set corresponding to the first PUSCH transmission time belongs and list 2 to which the target candidate set corresponding to the second PUSCH transmission time belongs can be the same set list or different set lists.

[0091] The second bit, when the current target candidate set indicated by the first bit belongs to the second set list, indicates which of the first power control parameters (first target P0) of the first PUSCH transmission timing (associated with the PUSCH transmission timing of SRS resources or SRS resource groups in the first SRS resource set) belongs to the second candidate set. For example, "0" indicates that the first target P0 is the first P0 in the set, and "1" indicates that the first target P0 is the second P0 in the set. In this case, the first candidate set of the first power control parameters of the first PUSCH transmission timing is not used to determine the first target P0. Here, the current target candidate set is the target candidate set of the first power control parameters of the first PUSCH transmission timing.

[0092] The third bit, when the current target candidate set indicated by the first bit belongs to the second set list, indicates which part of the second candidate set the first power control parameter (second target P0) of the second PUSCH transmission timing (associated with the PUSCH transmission timing of SRS resources or SRS resource groups in the second SRS resource set) belongs to. For example, "0" indicates that the second target P0 is the first P0 in the set, and "1" indicates that the second target P0 is the second P0 in the set. In this case, the first candidate set of the first power control parameter of the second PUSCH transmission timing is not used to determine the second target P0. Here, the current target candidate set is the target candidate set of the first power control parameter of the second PUSCH transmission timing.

[0093] For the first candidate set, considering that each set in the first set list may only include one P0, the second and third bits have no specific meaning when the first bit indicates that the first target parameter set is the first candidate set. Of course, if each set in the first set list includes multiple P0s, the first power control parameters for the first PUSCH transmission timing and the first power control parameters for the second PUSCH transmission timing will be further specified based on pre-configuration or pre-definition.

[0094] Optionally, the first bit is the most significant bit of the power control parameter indication field.

[0095] Specifically, the terminal interprets the different values ​​of the 3 bits in the power control parameter indication field as shown in Table 1, Table 2, or Table 3 below. Here, the target first parameter set is the set belonging to the first set list, and the target second parameter set is the set belonging to the second set list.

[0096] Table 1

[0097]

[0098] Table 2

[0099]

[0100] Table 3

[0101]

[0102] In the implementation of Table 3, the terminal first interprets the first bit of the power control parameter indication field, and then interprets the next two bits when the first bit is 1.

[0103] In Tables 1-3 above, the determination of the first set of target parameters and the second set of target parameters can be achieved as follows:

[0104] Example 1: The network-side device configures a first set list p0-AlphaSets. For PUSCH transmission timing associated with SRS resources or SRS resource groups in the first SRS resource set, the target first parameter set corresponds to the first first parameter set P0-PUSCH-AlphaSet in p0-AlphaSets. For PUSCH transmission timing associated with SRS resources or SRS resource groups in the second SRS resource set, the target first parameter set corresponds to p0-AlphaSets. The second first parameter set is P0-PUSCH-AlphaSet; in addition, the network-side device configures a second set list p0-PUSCH-SetList-r16. For the PUSCH transmission timing associated with SRS resources or SRS resource groups in the first SRS resource set, the target second parameter set corresponds to the P0-PUSCH-Set-r16 with the smallest index value (p0-PUSCH-SetId-r16) in p0-PUSCH-SetList-r16. For the PUSCH transmission timing associated with SRS resources or SRS resource groups in the second SRS resource set, the target second parameter set is the P0-PUSCH-Set-r16 with the second smallest p0-PUSCH-SetId-r16.

[0105] Example 2: The network-side device configures two first set lists, sri-PUSCH-MappingToAddModList1 and sri-PUSCH-MappingToAddModList2, which are associated with the first and second SRS resource sets, respectively. For the PUSCH transmission timing of SRS resources or SRS resource groups associated with the first SRS resource set, the target first parameter set corresponds to the first first parameter set SRI-PUSCH-PowerControl in sri-PUSCH-MappingToAddModList1, or the first parameter set SRI-PUSCH-PowerControlI=0. For the PUSCH transmission timing of SRS resources or SRS resource groups associated with the second SRS resource set, the target first parameter set corresponds to the first first parameter set SRI-PUSCH-PowerControl in PUSCH-MappingToAddModList2, or the first parameter set SRI-PUSCH-PowerControl with sri-PUSCH-PowerControlI=0, or the first parameter set SRI-PUSCH-PowerControl with sri-PUSCH-PowerControlI=1; in addition, the network-side device configures two second set lists p0-PUSCH-SetList-r16 1. p0-PUSCH-SetList-r16 2. Associated with the first and second SRS resource sets respectively. For the PUSCH transmission timing of the SRS resource or SRS resource group associated with the first SRS resource set, the target second parameter set corresponds to the P0-PUSCH-Set-r16 with the smallest p0-PUSCH-SetId-r16 in p0-PUSCH-SetList-r16 1. For the PUSCH transmission timing of the SRS resource or SRS resource group associated with the second SRS resource set, the target second parameter set corresponds to the P0-PUSCH-Set-r16 with the smallest p0-PUSCH-SetId-r16 in p0-PUSCH-SetList-r16 2.

[0106] Furthermore, in this embodiment, when the power control parameter indication field has a bit size of 3 bits, optionally, when the downlink control information includes an SRI field,

[0107] If the SRI field is associated with a first SRS resource set, then the first bit of the power control parameter indication field indicates the first power control parameter associated with the PUSCH transmission timing of the first SRS resource or SRS resource group, and the second and third bits jointly indicate the first power control parameter associated with the PUSCH transmission timing of the second SRS resource or SRS resource group.

[0108] If the SRI field is associated with a second SRS resource set, then the first bit and the second bit of the power control parameter indication field jointly indicate the first power control parameter for the PUSCH transmission timing associated with the first SRS resource or SRS resource group, and the third bit indicates the first power control parameter for the PUSCH transmission timing associated with the second SRS resource or SRS resource group.

[0109] Wherein, the first SRS resource or SRS resource group belongs to the first SRS resource set, and the second SRS resource or SRS resource group belongs to the second SRS resource set.

[0110] Since the SRS resource or SRS resource group associated with the first PUSCH transmission time belongs to the first SRS resource set, the SRS resource or SRS resource group associated with the first PUSCH transmission time is the first SRS resource or SRS resource group; since the SRS resource or SRS resource group associated with the second PUSCH transmission time belongs to the second SRS resource set, the SRS resource or SRS resource group associated with the second PUSCH transmission time is the second SRS resource or SRS resource group.

[0111] Therefore, for a DCI that includes an SRI field and is associated with a first SRS resource set, the candidate parameter set for the first power control parameter of the first PUSCH transmission timing can be determined. In this case, the first bit of the power control parameter indication field indicates the first power control parameter associated with the first SRS resource or SRS resource group, i.e., the source of the first target P0 of the first PUSCH transmission timing. For example, "0" indicates that the first target P0 originates from the first candidate set of the candidate parameter set, and "1" indicates that the first target P0 originates from the second candidate set of the candidate parameter set. Subsequently, the second and third bits jointly indicate the first power control parameter associated with the second SRS resource or SRS resource group, i.e., the source of the second target P0 of the second PUSCH transmission timing. For example, "00" indicates that the second target P0 originates from the first candidate set of the candidate parameter set, "01" indicates that the second target P0 originates from the first P0 of the second candidate set of the candidate parameter set, and "10" indicates that the second target P0 originates from the second P0 of the second candidate set of the candidate parameter set.

[0112] If the DCI includes an SRI field and this SRI field is associated with a second SRS resource set, then the candidate parameter set for the first power control parameter of the second PUSCH transmission timing can be determined. In this case, the first and second bits of the power control parameter indication field jointly indicate the first power control parameter associated with the first SRS resource or SRS resource group, i.e., the source of the first target P0 of the first PUSCH transmission timing. For example, "00" indicates that the first target P0 originates from the first candidate set of the candidate parameter set, "01" indicates that the first target P0 originates from the first P0 of the second candidate set of the candidate parameter set, and "10" indicates that the first target P0 originates from the second P0 of the second candidate set of the candidate parameter set. Then, the third bit indicates the first power control parameter associated with the second SRS resource or SRS resource group, i.e., the source of the second target P0 of the second PUSCH transmission timing. For example, "0" indicates that the second target P0 originates from the first candidate set of the candidate parameter set, and "1" indicates that the second target P0 originates from the second candidate set of the candidate parameter set.

[0113] Optionally, in this embodiment, the first SRS resource set and the second SRS resource set are distinguished based on the following:

[0114] SRS resource set index size;

[0115] SRS resource set configuration order;

[0116] MAC CE indicates; or,

[0117] Configuration information for high-level signaling.

[0118] For example, the SRS resource set with the larger index is the first SRS resource set, and the SRS resource set with the smaller index is the second SRS resource set; the SRS resource set configured first is the first SRS resource set, and the SRS resource set configured later is the second SRS resource set.

[0119] Alternatively, in this embodiment, the method further includes:

[0120] The terminal determines the second power control parameter for when to transmit PUSCH.

[0121] Here, the second power control parameter can be the path loss reference signal PL-RS. In the following embodiments, PL-RS can be used to directly replace the second power control parameter. Of course, other implementations of the second power control parameter can also be applied to the embodiments of this application, and will not be described in detail here.

[0122] Optionally, the second power control parameter for determining the PUSCH transmission timing includes:

[0123] Based on the downlink control information and the associated SRS resources or SRS resource groups, determine the second power control parameters for the PUSCH transmission timing; or,

[0124] The second power control parameter for determining the timing of PUSCH transmission is determined based on at least one second power control parameter associated with the target transmission resource.

[0125] Here, the target transmission resource can be a PUCCH resource or a CORESET. The second power control parameter used by the terminal to determine the timing of PUSCH transmission can be at least one second power control parameter associated with the target transmission resource, such as the first of at least one second power control parameter.

[0126] The terminal can also determine the second power control parameters for the PUSCH transmission timing based on the received DCI and the SRS resources or SRS resource groups associated with the PUSCH transmission timing.

[0127] Optionally, the step of determining the second power control parameter for PUSCH transmission timing based on the downlink control information and the associated SRS resource or SRS resource group includes:

[0128] If the downlink control information does not include the SRI field of the associated target SRS resource set, a second power control parameter is used to determine the PUSCH transmission timing of the associated target SRS resource or resource group in the second target parameter set.

[0129] Optionally, the second target parameter set is the first target set in the first set list, and the target SRS resource or resource group belongs to the target SRS resource set.

[0130] Here, the terminal is able to determine the second power control parameter for the PUSCH transmission timing of the associated target SRS resource or resource group (the SRS resource or resource group belonging to the target SRS resource set) in the first target set (second target parameter set) of the first set list, even if the DCI does not include the SRI domain of the associated target SRS resource set.

[0131] The first target set can be determined based on a predefined or preconfigured index, such as the set with index 0 in the first set list; the first target set can also be determined based on a predefined or preconfigured sorting order, such as the first set in the first set list. Optionally, the first target set is a list of first sets associated with the target SRS resource set.

[0132] For example, when the DCI does not contain an SRI field associated with the first SRS resource set, the target PL-RS associated with the PUSCH transmission timing from the SRS resource or SRS resource group of the first SRS resource set is the PL-RS in the set with index 0 in the first set list. When the DCI does not contain an SRI field associated with the second SRS resource set, the target PL-RS associated with the PUSCH transmission timing from the SRS resource or SRS resource group of the second SRS resource set is the PL-RS in the set with index 0 or 1 in the first set list. For example, the second target parameter set is sri-PUSCH-power control, which is the set of PL-RS obtained from an existing SRI field or a predefined set index ID=0.

[0133] Assume the network-side device is configured with a first set list sri-PUSCH-MappingToAddModList, which contains two sets SRI-PUSCH-PowerControl, corresponding to indices (sri-PUSCH-PowerControlId) of 0 and 1 respectively. When the DCI for scheduling PUSCH does not contain any SRI domain, the path loss reference signal associated with the PUSCH transmission timing from the first SRS resource set or SRS resource group is the path loss reference signal associated in SRI-PUSCH-PowerControl with sri-PUSCH-PowerControlId=0; the path loss reference signal associated with the PUSCH transmission timing from the second SRS resource set or resource group is the path loss reference signal associated in SRI-PUSCH-PowerControl with sri-PUSCH-PowerControlId=1.

[0134] Since the first target set may contain multiple PL-RS, the target PL-RS in the first target set can be determined based on predefined or preconfigured settings.

[0135] For example, when the DCI does not contain an SRI field associated with the first SRS resource set, the target PL-RS corresponding to the PUSCH transmission timing associated with an SRS resource or SRS resource group from the first SRS resource set is the first PL-RS in the first target set. When the DCI does not contain an SRI field associated with the second SRS resource set, the target PL-RS corresponding to the PUSCH transmission timing associated with an SRS resource or SRS resource group from the second SRS resource set is the second PL-RS in the first target set. The first target set can be the set corresponding to index 0 or the smallest index in the first set list.

[0136] Alternatively, in this embodiment, the method further includes:

[0137] A Media Access Control Unit (MAC CE) is received; wherein the MAC CE includes a first power control parameter update indication field, the first power control parameter update indication field indicating at least one set index and at least one parameter index;

[0138] Update the indication field according to the first power control parameter, and update the set corresponding to the at least one set index according to the at least one parameter index.

[0139] Here, the set of second power control parameters includes an index indicating a specific second power control parameter. Thus, the network-side device updates the second power control parameters based on demand, sending a MAC CE including a first power control parameter update indication field. After receiving the MAC CE, the terminal updates the second power control parameter index in the set corresponding to at least one set index of the MAC CE using at least one parameter index of the MAC CE.

[0140] Wherein, the at least one set index is an index of a set in the first set list. In this case, the first set list is sri-PUSCH-MappingToAddModList. The at least one parameter index is used to indicate the updated PL-RS index in the set corresponding to the at least one set index.

[0141] For example, the format of MAC CE is as follows: Figure 9 As shown, in the first power control parameter update indication field, each field used to indicate the set index is a SRI ID field, and each field used to indicate the parameter index is a PUSCH Pathloss Reference RSID field. Thus, assuming that the index value range of the set including the second power control parameters is 0~31, then in the first power control parameter update indication field of the MAC CE, each SRI ID field is 5 bits long.

[0142] Optionally, the MAC CE further includes a second power control parameter update indication field, which indicates the SRS resource set associated with the set corresponding to the at least one set index, or the set list to which the set corresponding to the at least one set index belongs.

[0143] In this way, updating the indication field with the second power control parameter can clearly identify the SRS resource set or list of sets associated with the set corresponding to the at least one set index. For example, the format of MAC CE is as follows: Figure 9 As shown, the second power control parameter update indication field is the S field.

[0144] The second power control parameter update indication field can be a reused field of the MAC CE, or it can be a new field.

[0145] Specifically, a "0" in the second power control parameter update indication field indicates that at least one set index indicated by the first power control parameter update indication field in the MAC CE corresponds to a set associated with the first SRS resource set; a "1" in the MAC CE indicates that at least one set index indicated by the first power control parameter update indication field in the MAC CE corresponds to a set associated with the second SRS resource set.

[0146] Alternatively, if the second power control parameter update indication field is "0", it indicates that the set corresponding to at least one set index indicated by the first power control parameter update indication field in the MAC CE belongs to the first set list, which is a first set list associated with the first SRS resource set or the first SRI field; if it is "1", it indicates that the set corresponding to at least one set index indicated by the first power control parameter update indication field in the MAC CE belongs to the first set list, which is a first set list associated with the second SRS resource set or the second SRI field.

[0147] Alternatively, if the second power control parameter update indication field is "0", it means that the set corresponding to at least one set index indicated by the first power control parameter update indication field in the MAC CE is associated with the first set list, and the first set list is the first set list associated with the first SRS resource set; if it is "1", it means that at least one parameter index indicated by the first power control parameter update indication field in the MAC CE is the corresponding parameter index in the Nth set after the set used to update the at least one set index.

[0148] Optionally, if the second power control parameter update indication field is a preset value, the Nth set after the set corresponding to the at least one set index is updated according to the at least one parameter index, where N is the target offset value.

[0149] If the preset value is 1 as mentioned above, and assuming N=2, the set index indicated by the first power control parameter update indication field is 1, then when the second power control parameter update indication field is "1", the PL-RS index will be updated to the PL-RS index indicated by the first power control parameter update indication field in the set with set index 3 (1+2).

[0150] Wherein, the target offset value is the total number of sets in the second target set list, and the second target set list is the first set list of associated target SRS resource sets.

[0151] If the target SRS resource set is the first SRS resource set, then the target offset value is the total number of sets in the first set list associated with the first SRS resource set; if the target SRS resource set is the second SRS resource set, then the target offset value is the total number of sets in the first set list associated with the second SRS resource set.

[0152] Of course, the target offset value can be configured by higher-level signaling; it can also be determined by predefined parameters, such as N=16.

[0153] Optionally, the MAC CE further includes a third power control parameter update indication field, which indicates the updated parameter identifier corresponding to the at least one parameter index in the set corresponding to the at least one set index.

[0154] In other words, when faced with a situation where at least one set index corresponds to a set that includes multiple parameter indices, the identifier indicated by the third power control parameter update field can be used to clarify the specific update object.

[0155] Similarly, the third power control parameter update indication field can be a reused field of MAC CE, or a new field can be added.

[0156] Specifically, a "0" value in the third power control parameter update indication field indicates the first associated PL-RS index in the set indicated by the update set index corresponding to the parameter index of the MAC CE; a "1" value indicates the second associated PL-RS index in the set indicated by the update set index corresponding to the parameter index of the MAC CE.

[0157] Combination Figure 9 The format of the MAC CE shown contains 2L-5 SRI IDs:

[0158] Example 1: An S field of "0" indicates an SRI ID. i The domain indicating the SRI PUSCH power control belongs to the first set list sri-PUSCH-MappingToAddModList; a value of "1" indicates the SRI ID. i The domain indicator SRI PUSCH powercontrol belongs to another first set list sri-PUSCH-MappingToAddModList.

[0159] Example 2: An S field of "0" indicates an SRI ID. i The field indicates the SRI PUSCH power control associated with the first SRS resource set; a value of "1" indicates the SRI ID. iThe field indicates the SRI PUSCH powercontrol associated with the second SRS resource set.

[0160] Example 3: An S field of "0" indicates an SRI ID. i The field indicates the SRI PUSCH power control associated with the first SRS resource set; a value of "1" indicates the SRI ID. i The field indicates the SRI PUSCH powercontrol associated with the second SRS resource set.

[0161] for Figure 9 Other fields in the format of the MAC CE shown are as follows: the R field is a reserved field; the C field indicates whether there are two SRI ID fields in the last byte of the MAC CE; the Serving CELL ID field is the serving cell identifier; and the BWP ID field is the BWP identifier.

[0178] When the second bit of the power control parameter indication field indicates that the current target candidate set indicated by the first bit belongs to the second set list, the power control parameter of the first power control parameter of the first PUSCH transmission timing in the current target candidate set is indicated by the second bit. The SRS resource or SRS resource group associated with the first PUSCH transmission timing belongs to the first SRS resource set.

[0179] When the third bit of the power control parameter indication field indicates that the current target candidate set indicated by the first bit belongs to the second set list, the power control parameter of the first power control parameter of the second PUSCH transmission timing in the current target candidate set is indicated, and the SRS resource or SRS resource group associated with the second PUSCH transmission timing belongs to the second SRS resource set.

[0180] Optionally, the first target set list to which the target candidate set corresponding to the first PUSCH transmission timing belongs is the same as the first target set list to which the target candidate set corresponding to the second PUSCH transmission timing belongs.

[0181] Optionally, the first target set list to which the target candidate set corresponding to the first PUSCH transmission timing belongs is different from the first target set list to which the target candidate set corresponding to the second PUSCH transmission timing belongs.

[0182] Optionally, the first bit is the most significant bit of the power control parameter indication field.

[0183] Optionally, if the downlink control information includes an SRI field,

[0208] The DCI received by the device includes at least one power control parameter indication field, which indicates the first power control parameter for different PUSCH transmission timings, and the PUSCH transmission timing is associated with an SRS resource or SRS resource group. Thus, by combining the correspondence between TRPs and SRS resources or SRS resource groups, when facing multiple TRPs, the DCI including at least one power control parameter indication field can indicate the first power control parameter for the PUSCH transmission timings of multiple TRPs, thereby satisfying the transmission requirements of multiple TRPs.

[0213] The downlink control information includes at least one power control parameter indication field, which indicates a first power control parameter for different physical uplink shared channel (PUSCH) transmission timings, wherein the PUSCH transmission timings are associated with SRS resources or SRS resource groups.

[0214] Here, the DCI sent by the network-side device includes at least one power control parameter indication field. This power control parameter indication field indicates the first power control parameters for different PUSCH transmission timings, and the PUSCH transmission timings are associated with SRS resources or SRS resource groups. Thus, when the terminal receives this DCI, and considering the correspondence between TRPs and SRS resources or SRS resource groups, it can, when faced with multiple TRPs, indicate the first power control parameters for the PUSCH transmission timings of multiple TRPs through the DCI including at least one power control parameter indication field, thereby satisfying the transmission requirements of multiple TRPs.

[0226] When the second bit of the power control parameter indication field indicates that the current target candidate set indicated by the first bit belongs to the second set list, the power control parameter of the first power control parameter of the first PUSCH transmission timing in the current target candidate set is indicated by the second bit. The SRS resource or SRS resource group associated with the first PUSCH transmission timing belongs to the first SRS resource set.

[0227] When the third bit of the power control parameter indication field indicates that the current target candidate set indicated by the first bit belongs to the second set list, the power control parameter of the first power control parameter of the second PUSCH transmission timing in the current target candidate set is indicated, and the SRS resource or SRS resource group associated with the second PUSCH transmission timing belongs to the second SRS resource set.

[0228] Optionally, the first target set list to which the target candidate set corresponding to the first PUSCH transmission timing belongs is the same as the first target set list to which the target candidate set corresponding to the second PUSCH transmission timing belongs.

[0229] Optionally, the first target set list to which the target candidate set corresponding to the first PUSCH transmission timing belongs is different from the first target set list to which the target candidate set corresponding to the second PUSCH transmission timing belongs.

[0230] Optionally, the first bit is the most significant bit of the power control parameter indication field.

[0231] Optionally, if the downlink control information includes an SRI field,

[0232] If the SRI field is associated with a first SRS resource set, then the first bit of the power control parameter indication field indicates the first power control parameter associated with the PUSCH transmission timing of the first SRS resource or SRS resource group, and the second and third bits jointly indicate the first power control parameter associated with the PUSCH transmission timing of the second SRS resource or SRS resource group.

[0233] If the SRI field is associated with a second SRS resource set, then the first bit and the second bit of the power control parameter indication field jointly indicate the first power control parameter for the PUSCH transmission timing associated with the first SRS resource or SRS resource group, and the third bit indicates the first power control parameter for the PUSCH transmission timing associated with the second SRS resource or SRS resource group.

[0234] Wherein, the first SRS resource or SRS resource group belongs to the first SRS resource set, and the second SRS resource or SRS resource group belongs to the second SRS resource set.

[0235] Optionally, the first SRS resource set and the second SRS resource set are distinguished based on the following:

[0236] SRS resource set index size;

[0237] SRS resource set configuration order;

[0238] MAC CE indicates; or,

[0239] Configuration information for high-level signaling.

[0240] Optionally, the method further includes:

[0242] The MAC CE includes a first power control parameter update indication field, which indicates at least one set index and at least one parameter index.

[0243] Optionally, the MAC CE further includes a second power control parameter update indication field, which indicates the SRS resource set associated with the set corresponding to the at least one set index, or the set list to which the set corresponding to the at least one set index belongs.

[0244] Optionally, if the second power control parameter update indication field is a preset value, the Nth set after the set corresponding to the at least one set index is updated according to the at least one parameter index, where N is the target offset value.

[0245] Optionally, the target offset value is the total number of sets in the second target set list, where the second target set list is the first set list of associated target SRS resource sets.

[0246] Optionally, the MAC CE further includes a third power control parameter update indication field, which indicates the identifier of the parameter index to be updated in the set corresponding to the at least one set index.

[0247] The method transmits a DCI including at least one power control parameter indication field, which indicates the first power control parameter for different PUSCH transmission timings, and the PUSCH transmission timing is associated with an SRS resource or SRS resource group. Thus, when the terminal receives this DCI, and considering the correspondence between the TRP and the SRS resource or SRS resource group, when faced with multiple TRPs, the DCI including at least one power control parameter indication field can indicate the first power control parameter for the PUSCH transmission timings of multiple TRPs, thereby satisfying the transmission requirements of multiple TRPs.

[0248] It should be noted that this method is implemented in conjunction with the power control parameter indication method executed by the terminal described above. The implementation of the power control parameter indication method executed by the terminal described above is applicable to this method and can achieve the same technical effect.
