[0042] The transmission processing method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0043] As shown in the method for indicating a power control parameter according to an embodiment of the present application, the method includes the following steps. Figure 2

[0044] Step 201: The terminal receives downlink control information.

[0045] Step 202: The terminal performs power control according to the downlink control information.

[0046] ​The downlink control information includes at least one power control parameter indication field, and the power control parameter indication field indicates a first power control parameter of different physical uplink shared channel (PUSCH) transmission occasions associated with a channel sounding reference signal (SRS) resource or an SRS resource group.

[0047] Here, the downlink control information (DCI) received by the terminal includes at least one power control parameter indication field, and the power control parameter indication field indicates a first power control parameter of different PUSCH transmission occasions associated with an SRS resource or an SRS resource group. In this way, in the face of multiple TRPs, by including at least one power control parameter indication field in the DCI, the first power control parameter of the PUSCH transmission occasions of the multiple TRPs can be indicated to meet the transmission requirements of the multiple TRPs in combination with the correspondence between the TRPs and the SRS resources or the SRS resource groups (i.e., each TRP has a corresponding SRS resource or SRS resource group).

[0048] Here, the SRS resource group is a plurality of (a group of) SRS resources. Alternatively, the power control parameter indication field can also be understood as an open-loop power control parameter set indication field. Correspondingly, the first power control parameter is a power control parameter P0 used to determine the transmission 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 applicable to the embodiments of the present application, and will not be described here.

[0049] Alternatively, the SRS resources or the SRS resource groups associated with the different PUSCH transmission occasions are different.

[0050] It should be understood that different SRS resources or SRS resource groups are applicable to different TRPs, so when the SRS resources or the SRS resource groups associated with the different PUSCH transmission occasions are different, one power control parameter indication field can indicate the first power control parameter of the PUSCH transmission occasions of different TRPs.

[0051] Thus, for the indication of P0 of PUSCH transmission occasions of multiple TRPs, such as TRP1, TRP2, TRP3 and TRP4, different from each other in terms of SRS resource or SRS resource group, in the DCI, the P0 of different PUSCH transmission occasions can be indicated two by two through two power control parameter indication fields, such as power control parameter indication field 1 indicating the P0 of PUSCH transmission occasions of TRP1 and TRP2, and power control parameter indication field 2 indicating the P0 of PUSCH transmission occasions of TRP3 and TRP4. Of course, the P0 of PUSCH transmission occasions of TRP1, TRP2, TRP3 and TRP4 can also be indicated through only one power control parameter indication field.

[0052] It should also be known that the PUSCH transmission occasion can be one slot, one nominal repeated transmission occasion, one actual repeated transmission occasion or a plurality of consecutive OFDM symbols, etc.

[0053] Optionally, in this embodiment, the downlink control information further comprises an SRI field, the SRI field indicating a candidate parameter set of the first power control parameter of the PUSCH transmission occasion associated with the SRS resource or the SRS resource group.

[0054] That is, the DCI can further comprise an SRI field for indicating a candidate parameter set of the first power control parameter of the PUSCH transmission occasion associated with the SRS resource or the SRS resource group.

[0055] Optionally, in this embodiment, the candidate parameter set of the first power control parameter of at least one PUSCH transmission occasion among the different PUSCH transmission occasions is predefined or preconfigured.

[0056] That is, the first power control parameter indicated by the power control parameter indication field belongs to a predefined or preconfigured candidate parameter set. Accordingly, the DCI does not comprise any SRI field or comprises only one SRI field.

[0057] Optionally, the candidate parameter set comprises at least one of the following:

[0058] a first candidate set;

[0059] a second candidate set;

[0060] wherein the first candidate set belongs to a first set list; and the second candidate set belongs to a second set list.

[0061] Thus, the candidate parameter set of the first power control parameter can be a set belonging to the first set list only, a set belonging to the second set list only, or a set belonging to both the first set list and the second set list.

[0062] It should be noted that in this embodiment, the first set list and the second set list are provided for determining the candidate parameter set, thereby obtaining the first power control parameter. Here, each set in the first set list and the second set list includes the first power control parameter. However, the first set list is different from the second set list. In each set of the first set list, in addition to the first power control parameter, other power control parameters such as alpha, path loss reference signal, and closed loop power adjustment index are also included. Each set of the second set list is a set dedicated to the first power control parameter and does not include other power control parameters. Specifically, the first set list can be an SRI mapping PUSCH power control parameter addition update list sri-PUSCH-MappingToAddModList or a P0 and alpha set list p0-AlphaSets, and the second set list can be an open loop power control parameter set list p0-PUSCH-SetList-r16.

[0063] Of course, the first set list and the second set list can each include one or more lists. In this embodiment, the first set list and the second set list are configured by high layer signaling or predefined.

[0064] Alternatively, the first set list and the second set list are respectively associated with an SRS resource set.

[0065] Here, the first set list and the second set list can be associated with the same SRS resource set or different SRS resource sets.

[0066] Here, the SRS resource set corresponds to different TRPs, such as SRS resources or SRS resource groups in SRS resource set 1 corresponding to TRP1 for transmission by TRP1, and SRS resources or SRS resource groups in SRS resource set 2 corresponding to TRP2 for transmission by 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 respectively associated with different SRS resource sets, which are not listed here.

[0067] The SRS resource set is configured by RRC and includes multiple SRS resources. The SRS resource group is indicated by the SRI field and is a subset of all SRS resources in the SRS resource set.

[0068] In this embodiment, the sets in the first set list (i.e., the first parameter set) can be one or more, and the sets in the second set list (i.e., the second parameter set) can be one or more.

[0069] Therefore, the candidate parameter set indicated by the SRI field described above is arranged in order or indexed, and when the candidate parameter set is the first candidate set, it is indicated as a certain first parameter set in the first set list, such as the first one 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 is indicated as a certain second parameter set in the second set list, such as the first one or the second parameter set with an index value of 0, or the second parameter set with the smallest index value.

[0070] And the pre-defined or pre-configured candidate parameter set can also be arranged in order or indexed, and when the candidate parameter set is the first candidate set, the pre-defined or pre-configured 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 pre-defined or pre-configured candidate parameter set corresponds to the arrangement order or index value in the second set list.

[0071] It should be noted that in this embodiment, the terminal needs to determine the candidate parameter set first to determine P0 of the PUSCH transmission occasion after receiving the DCI.

[0072] And for the case where the first set list and the second set list are configured or pre-defined by the higher layer signaling, in this embodiment, the determined candidate parameter set includes the first candidate set and the second candidate set. For example, the SRS resource or the SRS resource group belongs to the SRS resource set 1, and for the PUSCH transmission occasion associated with the SRS resource or the SRS resource group from the SRS resource set 1, the first candidate set can be indicated by the SRI field in the DCI associated with the SRS resource set 1 in the first set list, or selected in the first set list based on pre-definition or pre-configuration; the second candidate set can be indicated by the SRI field in the DCI associated with the SRS resource set 1 in the second set list, or selected in the second set list based on pre-definition or pre-configuration. Then, the target parameter set is further determined in the first candidate set and the second candidate set to obtain the first power control parameter. If the SRS resource or the SRS resource group belongs to the SRS resource set 2, for the PUSCH transmission occasion associated with the SRS resource or the SRS resource group in the SRS resource set 2, the first candidate set and the second candidate set can also be determined in the above-mentioned manner.

[0073] Of course, the first candidate set of the first power control parameter of the PUSCH transmission occasion associated with the SRS resource or SRS resource group in the SRS resource set 1 is set 1, and the first candidate set of the first power control parameter of the PUSCH transmission occasion associated with the SRS resource or SRS resource group from the SRS resource set 2 is set 2. The first set list to which set 1 and set 2 belong can be the same or different.

[0074] The different PUSCH transmission occasions associated with different SRS resources or SRS resource groups can have different candidate parameter sets of P0 in the same set list. Continuing the above example, assuming that for the PUSCH transmission occasion associated with the SRS resource or SRS resource group from the 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, for the PUSCH transmission occasion associated with the SRS resource or SRS resource group from the SRS resource set 2, the first candidate set can be indicated by the SRI field associated with the SRS resource set 2 in the DCI in the first set list, or selected in the first set list based on predefinition or preconfiguration, and the first candidate set at this time is determined to be the second set in the first set list; the second candidate set can be indicated by the SRI field associated with the SRS resource set 2 in the DCI in the second set list, or selected in the second set list based on predefinition or preconfiguration, and the second candidate set at this time is determined to be the set with the second smallest index value in the second set list.

[0075] Of course, for different PUSCH transmission occasions associated with different SRS resources or SRS resource groups, the candidate parameter sets of P0 in the same set list can also use the same set, which will not be described here.

[0076] Optionally, the bit size of the power control parameter indication field is 3 bits.

[0077] At this time, the power control parameter indication field with a bit size of 3 bits will specifically indicate the first power control parameter of the first PUSCH transmission occasion and the first power control parameter of the second PUSCH transmission occasion.

[0078] Of course, if the power control parameter indication field is to indicate the first power control parameter of the PUSCH transmission occasion associated with two or more different SRS resources or resource groups, the number of bits of 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 for codebook or non-codebook transmission plus 1.

[0079] In the embodiment, when the bit size of the power control parameter indication field is 3 bits, and optionally, the downlink control information does not include an SRI field,

[0080] 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 a first target set list, and the first target parameter set is a target parameter set of the first power control parameter of the different PUSCH transmission occasions.

[0081] The second bit of the power control parameter indication field indicates, when the current target candidate set indicated by the first bit belongs to a second set list, the power control parameter in the current target candidate set as the first power control parameter of the first PUSCH transmission occasion, the SRS resource or SRS resource group associated with the first PUSCH transmission occasion belongs to a first SRS resource set.

[0082] The third bit of the power control parameter indication field indicates, when the current target candidate set indicated by the first bit belongs to a second set list, the power control parameter in the current target candidate set as the first power control parameter of the second PUSCH transmission occasion, the SRS resource or SRS resource group associated with the second PUSCH transmission occasion belongs to a second SRS resource set.

[0083] Wherein, the first target set list to which the target candidate set corresponding to the first PUSCH transmission occasion belongs is the same as the first target set list to which the target candidate set corresponding to the second PUSCH transmission occasion belongs.

[0084] Alternatively, the first target set list to which the target candidate set corresponding to the first PUSCH transmission occasion belongs is different from the first target set list to which the target candidate set corresponding to the second PUSCH transmission occasion belongs.

[0085] Here, the first target set list can be a first set list or a second set list.

[0086] The DCI not including the SRI field can also be understood as: all SRI fields in the DCI are 0 bits. Because the DCI does not include the SRI field, the candidate parameter set of the first power control parameter of the first PUSCH transmission occasion and the candidate parameter set of the first power control parameter of the second PUSCH transmission occasion are determined based on predefinition or preconfiguration.

[0087] And since the candidate parameter set can include a first candidate set and a second candidate set, the first power control parameter needs to further determine the target candidate set as the target parameter set in the first candidate set and the second candidate set, so as to determine the first power control parameter of the PUSCH transmission occasion in the target parameter set.

[0088] At this time, in the 3-bit power control parameter indication field, the first bit indicates that the first target parameter set is a target candidate set belonging to the first target set list, and the first target parameter set is a target parameter set of the first power control parameter of different PUSCH transmission occasions, that is, the first power control parameters of the first PUSCH transmission occasion and the second PUSCH transmission occasion indicated by the power control parameter indication field are either both sets belonging to the first set list or both sets belonging 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.

[0089] It should be understood that even if the target candidate sets of the first power control parameters of different PUSCH transmission occasions both belong to the first set list, they can be different sets in the first set list, and similarly, even if the target parameter sets of the first power control parameters of different PUSCH transmission occasions both belong to the second set list, they can be different sets in the second set list. That is, the list 1 to which the target candidate set corresponding to the first PUSCH transmission occasion belongs and the list 2 to which the target candidate set corresponding to the second PUSCH transmission occasion belongs can be the same set list or different set lists.

[0090] The second bit indicates which one in the second candidate set of the first power control parameter (the first target P0) of the first PUSCH transmission occasion (the PUSCH transmission occasion associated with the SRS resource or SRS resource group in the first SRS resource set) when the first bit indicates that the current target candidate set belongs to the second set list. 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. At this time, the first candidate set of the first power control parameter of the first PUSCH transmission occasion 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 parameter of the first PUSCH transmission occasion.

[0091] The third bit indicates which one in the second candidate set of the first power control parameter (the second target P0) of the second PUSCH transmission occasion (the PUSCH transmission occasion associated with the SRS resource or SRS resource group in the second SRS resource set) when the first bit indicates that the current target candidate set belongs to the second set list. 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. At this time, the first candidate set of the first power control parameter of the second PUSCH transmission occasion 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 occasion.

[0092] For the first candidate set, considering that each set in the first set list can only include one P0, therefore, in the case that the first bit indicates that the first target parameter set is the first candidate set, the second bit and the third bit have no specific meaning. Of course, if each set in the first set list includes multiple P0s, the first power control parameter of the first PUSCH transmission occasion and the first power control parameter of the second PUSCH transmission occasion will be further specified based on pre-configuration or pre-definition.

[0093] Optionally, the first bit is the most significant bit of the power control parameter indication field.

[0094] Specifically, for different specific values of the power control parameter indication field 3 bits, the terminal understands as shown in Table 1, Table 2 or Table 3, wherein the target first parameter set is a set belonging to the first set list, and the target second parameter set is a set belonging to the second set list:

[0095] Table 1

[0096]

[0097] Table 2

[0098]

[0099] Table 3

[0100]

[0101] In the implementation of Table 3, the terminal first interprets the first bit of the power control parameter indication field, and then interprets the last two bits when the first bit is 1.

[0102] In the above Tables 1-3, the determination of the target first parameter set and the target second parameter set can be implemented as:

[0103] Example 1, the network side device configures a first set list p0-AlphaSets, for the PUSCH transmission occasion associated with the SRS resource or SRS resource group 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 the PUSCH transmission occasion associated with the SRS resource or SRS resource group in the second SRS resource set, the target first parameter set corresponds to the second first parameter set P0-PUSCH-AlphaSet in p0-AlphaSets; in addition, the network side device configures a second set list p0-PUSCH-SetList-r16, for the PUSCH transmission occasion associated with the SRS resource or SRS resource group in the first SRS resource set, the target second parameter set corresponds to the P0-PUSCH-Set-r16 with the minimum index value (p0-PUSCH-SetId-r16) in p0-PUSCH-SetList-r16, for the PUSCH transmission occasion associated with the SRS resource or SRS resource group in the second SRS resource set, the target second parameter set corresponds to the P0-PUSCH-Set-r16 with the second minimum index value (p0-PUSCH-SetId-r16) in p0-PUSCH-SetList-r16.

[0104] In Example 2, the network-side device configures two first set lists sri-PUSCH-MappingToAddModList1 and sri-PUSCH-MappingToAddModList2, respectively associated with the first and second SRS resource sets. For a PUSCH transmission occasion associated with an SRS resource or SRS resource group in 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-PowerControl with sri-PUSCH-PowerControlI = 0. For a PUSCH transmission occasion associated with an SRS resource or SRS resource group in the second SRS resource set, the target first parameter set corresponds to the first first parameter set SRI-PUSCH-PowerControl in sri-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 and p0-PUSCH-SetList-r16 2, respectively associated with the first and second SRS resource sets. For a PUSCH transmission occasion associated with an SRS resource or SRS resource group in 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 a PUSCH transmission occasion associated with an SRS resource or SRS resource group in 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.

[0105] In addition, in the embodiment, when the bit size of the power control parameter indication field is 3 bits, and the downlink control information includes one SRI field, the network-side device configures the first parameter set SRI-PUSCH-PowerControl in sri-PUSCH-MappingToAddModList1 and sri-PUSCH-MappingToAddModList2 as follows: the first parameter set SRI-PUSCH-PowerControl in sri-PUSCH-MappingToAddModList1 is configured as SRI-PUSCH-PowerControlI = 0, and the first parameter set SRI-PUSCH-PowerControl in sri-PUSCH-MappingToAddModList2 is configured as SRI-PUSCH-PowerControlI = 1.

[0106] If the SRI field is associated with the first SRS resource set, the first bit of the power control parameter indication field indicates the first power control parameter of the PUSCH transmission occasion associated with the first SRS resource or SRS resource group, and the second bit and the third bit jointly indicate the first power control parameter of the PUSCH transmission occasion associated with the second SRS resource or SRS resource group;

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

[0108] 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.

[0109] Since the SRS resource or SRS resource group associated with the first PUSCH transmission occasion belongs to the first SRS resource set, the SRS resource or SRS resource group associated with the first PUSCH transmission occasion is the first SRS resource or SRS resource group; and since the SRS resource or SRS resource group associated with the second PUSCH transmission occasion belongs to the second SRS resource set, the SRS resource or SRS resource group associated with the second PUSCH transmission occasion is the second SRS resource or SRS resource group.

[0110] Therefore, for the case that the DCI includes one SRI field and the SRI field is associated with the first SRS resource set, the candidate parameter set of the first power control parameter of the first PUSCH transmission occasion can be known. At this time, the first bit of the power control parameter indication field indicates the first power control parameter of the PUSCH transmission occasion associated with the first SRS resource or SRS resource group, i.e., the source of the first target P0 of the first PUSCH transmission occasion, for example: “0” indicates that the first target P0 is derived from the first candidate set of the candidate parameter set, and “1” indicates that the first target P0 is derived from the second candidate set of the candidate parameter set. Then, the second bit and the third bit jointly indicate the first power control parameter of the PUSCH transmission occasion associated with the second SRS resource or SRS resource group, i.e., the source of the second target P0 of the second PUSCH transmission occasion, for example: “00” indicates that the second target P0 is derived from the first candidate set of the candidate parameter set, “01” indicates that the second target P0 is derived from the first P0 of the second candidate set of the candidate parameter set, and “10” indicates that the second target P0 is derived from the second P0 of the second candidate set of the candidate parameter set.

[0111] For the case that the DCI includes one SRI field and the SRI field is associated with the second SRS resource set, the candidate parameter set of the first power control parameter of the second PUSCH transmission occasion is known. At this time, the first bit and the second bit of the power control parameter indication field jointly indicate the first power control parameter of the PUSCH transmission occasion associated with the first SRS resource or SRS resource group, i.e., the first target P0 source of the first PUSCH transmission occasion, for example: "00" indicates that the first target P0 is derived from the first candidate set of the candidate parameter set, "01" indicates that the first target P0 is derived from the first P0 of the second candidate set of the candidate parameter set, and "10" indicates that the first target P0 is derived from the second P0 of the second candidate set of the candidate parameter set. Then, the third bit indicates the first power control parameter of the PUSCH transmission occasion associated with the second SRS resource or SRS resource group, i.e., the second target P0 source of the second PUSCH transmission occasion, for example: "0" indicates that the second target P0 is derived from the first candidate set of the candidate parameter set, and "1" indicates that the second target P0 is derived from the second candidate set of the candidate parameter set.

[0112] Optionally, in the embodiment, the first SRS resource set and the second SRS resource set are distinguished based on the following:

[0113] SRS resource set index size;

[0114] SRS resource set configuration order;

[0115] MAC CE indication; or

[0116] configuration information of high-layer signaling.

[0117] For example, the SRS resource set with a large index is the first SRS resource set, and the SRS resource set with a small 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.

[0118] In addition, optionally, in the embodiment, the method further includes:

[0119] The terminal determines the second power control parameter of the PUSCH transmission occasion.

[0120] Here, the second power control parameter can be a path loss reference signal PL-RS. In the following embodiment, the PL-RS can be directly used to replace the second power control parameter, of course, other implementations of the second power control parameter can also be applicable to the embodiments of the present application, and will not be described here.

[0121] Optionally, the determination of the second power control parameter of the PUSCH transmission occasion includes:

[0122] determining the second power control parameter of the PUSCH transmission occasion according to the downlink control information and the associated SRS resource or SRS resource group; or

[0123] determining the second power control parameter of the PUSCH transmission occasion according to the at least one second power control parameter associated with the target transmission resource.

[0124] Here, the target transmission resource can be a PUCCH resource or a CORESET. The terminal determines the second power control parameter of the PUSCH transmission occasion according to the at least one second power control parameter associated with the target transmission resource, such as the first second power control parameter in the at least one second power control parameter.

[0125] The terminal can also determine the second power control parameter of the PUSCH transmission occasion according to the received DCI and the SRS resource or SRS resource group associated with the PUSCH transmission occasion.

[0126] Optionally, the determining the second power control parameter of the PUSCH transmission occasion according to the downlink control information and the associated SRS resource or SRS resource group comprises:

[0127] In the case that the downlink control information does not include the SRI field associated with the target SRS resource set, the terminal determines the second power control parameter of the PUSCH transmission occasion associated with the target SRS resource or resource group in the second target parameter set.

[0128] 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.

[0129] Here, the terminal can determine the second power control parameter of the PUSCH transmission occasion associated with the target SRS resource or resource group (the SRS resource or resource group belonging to the target SRS resource set) in the first target set (the second target parameter set) in the first set list in the case that the DCI does not include the SRI field associated with the target SRS resource set.

[0130] Here, 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 arrangement order, such as the first set in the first set list. Optionally, the first target set is the first set list associated with the target SRS resource set.

[0131] For example, when the DCI does not contain the SRI field associated with the first SRS resource set, the target PL-RS corresponding to the PUSCH transmission occasion associated with the SRS resource or SRS resource group from 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 the SRI field associated with the second SRS resource set, the target PL-RS corresponding to the PUSCH transmission occasion associated with the SRS resource or SRS resource group from 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 PL-RS set obtained by the existing SRI field or the predefined set index ID = 0;

[0132] Suppose the network side device configures a first set list sri-PUSCH-MappingToAddModList containing two sets SRI-PUSCH-PowerControl corresponding to index (sri-PUSCH-PowerControlId) 0 and 1 respectively; when the DCI scheduling PUSCH does not contain any SRI field, the path loss reference signal corresponding to the PUSCH transmission occasion associated with the SRS resource or SRS resource group from the first SRS resource set is the path loss reference signal associated in the SRI-PUSCH-PowerControl with sri-PUSCH-PowerControlId = 0; the path loss reference signal corresponding to the PUSCH transmission occasion associated with the SRS resource or resource group from the second SRS resource set is the path loss reference signal associated in the SRI-PUSCH-PowerControl with sri-PUSCH-PowerControlId = 1.

[0133] Since there can be multiple PL-RSs in the first target set, which PL-RS in the first target set is the target PL-RS can be determined based on predefinition or preconfiguration.

[0134] For example, when the DCI does not contain the SRI field associated with the first SRS resource set, the target PL-RS corresponding to the PUSCH transmission occasion associated with the 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 the SRI field associated with the second SRS resource set, the target PL-RS corresponding to the PUSCH transmission occasion associated with the 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.

[0135] In addition, optionally, in this embodiment, the method further comprises:

[0136] receiving a medium access control element, MAC CE; wherein the MAC CE comprises 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;

[0137] updating, according to the first power control parameter update indication field, a set corresponding to the at least one set index according to the at least one parameter index.

[0138] Here, in the set comprising the second power control parameter, the specific second power control parameter is indicated by the index of the second power control parameter. In this way, the network side device updates the second power control parameter based on the demand, sends the MAC CE comprising the first power control parameter update indication field, and the terminal updates the second power control parameter index with the at least one parameter index of the MAC CE in the set corresponding to the at least one set index of the MAC CE after receiving the MAC CE.

[0139] The at least one set index is the index of the set in the first set list. At this time, 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.

[0140] For example, the format of the MAC CE is as shown in Figure 9 In the first power control parameter update indication field, each field for indicating the set index, i.e., the SRI ID field, and each field for indicating the parameter index, i.e., the PUSCH Pathloss Reference RS ID field. In this way, assuming that the index of the set comprising the second power control parameter takes a value range of 0-31, each SRI ID field in the first power control parameter update indication field of the MAC CE has a length of 5 bits.

[0141] Optionally, the MAC CE further comprises a second power control parameter update indication field, the second power control parameter update indication field indicating a SRS resource set associated with the set corresponding to the at least one set index, or a set list to which the set corresponding to the at least one set index belongs.

[0142] In this way, the second power control parameter update indication field can clearly indicate 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. For example, the format of the MAC CE is as shown in Figure 9 The second power control parameter update indication field is the S field.

[0143] The second power control parameter update indication field can be multiplexed in a reserved field of the MAC CE, or a new field can be added.

[0144] Specifically, the second power control parameter update indication field is "0" to indicate that all the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE are associated with the first SRS resource set, and is "1" to indicate that all the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE are associated with the second SRS resource set.

[0145] Alternatively, the second power control parameter update indication field is "0" to indicate that the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE belong to the first set list, and is "1" to indicate that the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE belong to the first set list.

[0146] Alternatively, the second power control parameter update indication field is "0" to indicate that the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE belong to the first set list, and is "1" to indicate that the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE belong to the first set list.

[0147] Alternatively, the second power control parameter update indication field is "0" to indicate that the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE belong to the first set list, and is "1" to indicate that the sets corresponding to the at least one set index indicated by the first power control parameter update indication field in the MAC CE belong to the first set list.

[0148] The preset value is 1 as described above. Assuming that N=2, the set index indicated by the first power control parameter update indication field is 1, and the second power control parameter update indication field is "1", the PL-RS index in the set with the set index of 3 (1+2) is updated to the PL-RS index indicated by the first power control parameter update indication field.

[0149] 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 associated with the target SRS resource set.

[0150] If the target SRS resource set is the first SRS resource set, the target offset value is the total set quantity in the first set list associated with the first SRS resource set; if the target SRS resource set is the second SRS resource set, the target offset value is the total set quantity in the first set list associated with the second SRS resource set.

[0151] Of course, the target offset value can be configured by high layer signaling; can be determined by predefinition, such as N = 16.

[0152] Optionally, the MAC CE further comprises a third power control parameter update indication field, which indicates the parameter identification corresponding to the update of the at least one parameter index in the set corresponding to the at least one set index.

[0153] That is, in the case that the set corresponding to the at least one set index includes multiple parameter indexes, the specific update object can be indicated by the identification indicated by the third power control parameter update indication field.

[0154] Similarly, the third power control parameter update indication field can be multiplexed in the reserved field of the MAC CE; or a new field can be added.

[0155] Specifically, the third power control parameter update indication field is "0", which indicates that the parameter index in the MAC CE corresponds to the update of the first PL-RS index associated with the set indicated by the set index; and is "1", which indicates that the parameter index in the MAC CE corresponds to the update of the second PL-RS index associated with the set indicated by the set index.

[0156] In combination Figure 9 The format of the MAC CE shown, wherein the SRI ID is 2L-5:

[0157] Example one: the S field is "0", which indicates that the SRI ID i indicated by the S field belongs to the first set list sri-PUSCH-MappingToAddModList; and is "1", which indicates that the SRI PUSCH power control indicated by the S field belongs to another first set list sri-PUSCH-MappingToAddModList. i i indicated by the S field belongs to the first set list sri-PUSCH-MappingToAddModList; and is "1", which indicates that the SRI PUSCH power control indicated by the S field belongs to another first set list sri-PUSCH-MappingToAddModList.

[0158] Example two: the S field is "0", which indicates that the SRI ID i ​The field indicates SRI PUSCH power control associated with a second SRS resource set.

[0159] Example three: S field is "0" indicating SRI ID i The field indicates SRI PUSCH power control associated with a first SRS resource set; "1" indicating SRI ID i The field indicates SRI PUSCH power control associated with a second SRS resource set.

[0160] For Figure 9 For other fields in the format of the MAC CE shown in the table, 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 a serving cell identifier, and the BWP ID field is a BWP identifier.
