[0025] FIG. 2 shows a flowchart of a parameter adjusting method according to an embodiment of the present invention. As shown in FIG. 2, the parameter adjusting method may include the following steps:

[0026] Step 201: The UE receives a DCI.

[0027] Exemplarily, the UE receives the DCI from the network side device.

[0028] Exemplarily, the DCI is used to schedule a PUSCH transmission, where the PUSCH transmission is associated with a different target resource, and the target resource includes an SRS resource or an SRS resource group.

[0029] Step 202: The UE determines a target power control parameter corresponding to the PUSCH transmission based on the DCI.

[0030] In an embodiment of the present application, the target power control parameter is: Open loop power control parameters (e.g., {P0, α}); A parameter indicating a path loss reference signal PL-RS; a closed loop power control regulation status index.

[0031] Here, P0 and α are the target received power and the path loss compensation factor, and the closed-loop power control adjustment state index is used to indicate the closed-loop power control adjustment state that the SRS can maintain.

[0032] Optionally, in an embodiment of the present application, the DCI further includes a closed-loop power control adjustment state index and a power adjustment value corresponding to the closed-loop power control adjustment state index, where the target power control parameter includes the power adjustment value. Illustratively, the closed-loop power control adjustment state index may be a plurality of closed-loop power control adjustment state indexes, and the plurality of closed-loop power control adjustment state indexes may select different values.

[0033] Exemplarily, the TPC field in the DCI is used to indicate the power adjustment value, and the size of the TPC field is indicated by higher layer signaling. Furthermore, the higher layer signaling is RRC or MAC CE. For example, when the UE receives a MAC CE, if all the codepoints indicated by the MAC CE correspond to only one SRS resource, or if all the SRS resources corresponding to all the codepoints indicated by the MAC CE belong to the same SRS resource set, the size of the TPC field is 2 bits, otherwise, the size of the TPC field is 4 bits.

[0034] Optionally, in an embodiment of the present application, the target resource maintains a plurality of closed-loop power control adjustment states, where the closed-loop power control adjustment state satisfies at least one of: the closed-loop power control adjustment state is indicated by higher layer signaling; and the closed-loop power control adjustment state is associated with an SRS resource set including the target resource (i.e., an SRS resource or an SRS resource group associated with a PUSCH transmission).

[0035] Exemplarily, the UE receives higher layer signaling, which indicates to the UE that there are multiple closed-loop power control adjustment states for an SRS resource or an SRS resource group.

[0036] Illustratively, the SRS resource set configuration includes a closed-loop power control adjustment state index.

[0037] In the power control method according to the embodiment of the present application, in a scenario in which a PUSCH transmission is associated with N different target resources (SRS resources or SRS resource groups), after the UE receives a DCI for scheduling the PUSCH transmission from a network side device, the UE can determine target power control parameters corresponding to the cases in which the PUSCH transmission is associated with different target resources based on the DCI, and can further ensure that the PUSCH transmission adopts multiple sets of launch powers corresponding to multiple target resources, and guarantee the reliability of the PUSCH transmission.

[0038] Hereinafter, several power control methods according to the embodiments of the present application will be further described.

[0039] As an alternative solution, the target power control parameters include at least one power control parameter of a first set of power control parameters. Illustratively, the first set of power control parameters may be referred to as an SRI-PUSCH power control parameter set (SRI-PUSCH-Power Control). Furthermore, the first power control parameters may include at least one parameter of a target received power, a path loss compensation factor (e.g., P0 and α), an index of a path loss reference signal PL-RS, and a closed-loop power control state index (e.g., l in the above).

[0040] Optionally, in an embodiment of the present application, if the DCI includes an SRI field, the SRI field is used to indicate at least one first set of power control parameters, where the target power control parameter includes a power control parameter of the at least one first set of power control parameters. In one example, the first power control parameter may be referred to as SRI-PUSCH-PowerControl.

[0041] Further optionally, in an embodiment of the present application, after the above step 201, the power control method according to the embodiment of the present application may include the following step 201a.

[0042] Step 201a: The UE receives at least one first list and determining at least one set of first power control parameters corresponding to

[0043] Here, the first list has a mapping relationship with the first value list and the first value includes one of a field value of an SRI field in DCI and a value obtained after superimposing a different first offset value on the field value of the SRI field in DCI.

[0044] Here, the first offset value is the first offset value being configured by higher layer signaling; the first offset value being an integer; and the first offset value is associated with an SRS resource set that includes at least one of the target resources.

[0045] Illustratively, the at least first list is associated with Y SRS resource sets, listY is associated with at least one SRS resource set, and Y is a positive integer, where the Y SRS resource sets include different target resources associated with the PUSCH transmission.

[0046] Exemplarily, the field value of the SRI field in the DCI is an addition / modification field to which one or more sets of sri-PUSCH are mapped. list (sri-PUSCH-MappingToAddModList) (i.e. the first list ) to obtain one or more sets of first power control parameters (SRI-PUSCH-PowerControl). list is associated with an SRS resource set (this SRS resource set includes at least one SRS associated with the PUSCH).

[0047] Exemplarily, after a different first offset value (i.e., a first value) is multiplied on the field value of the SRI field, a set of sri-PUSCH-MappingToAddModList list , to obtain one or more sets of SRI-PUSCH-PowerControl.

[0048] Exemplarily, the SRI field in the DCI corresponds to at least one field value, and one field value corresponds to one first list For example, the DCI includes two SRI fields, and one SRI field corresponds to one SRI value (i.e., the field value of the SRI field), or the SRI field of the DCI jointly indicates two SRI values. It can be understood that one or more SRI values ​​indicated by the DCI are each a set of sri-PUSCH-MappingToAddModList list, to obtain one or more sets of SRI-PUSCH-PowerControl.

[0049] Further optionally, in an embodiment of the present application, the at least one set of first power control parameters indicated by an SRI field included in the DCI is associated with M target resources indicated by the SRI field, where M is a positive integer, and the M target resources satisfy at least one of the following: the M target resources belong to different SRS resource sets; and all SRS resources in an SRS resource group belong to the same SRS resource set.

[0050] Exemplarily, one or more sets of SRI-PUSCH-PowerControl indicated by the SRI field in the DCI are associated with one or more SRS resources / SRS resource groups indicated by the SRI field, for example, the SRS resources / SRS resource groups are from different SRS resource sets, and all SRS resources in one SRS resource group are from the same SRS resource set.

[0051] Optionally, in an embodiment of the present application, if the DCI does not include an SRI field, before step 202, the power adjustment method according to the embodiment of the present application may include the following steps:

[0052] Step 203: The UE determines at least one first set of power control parameters, and the target power control parameter is a power control parameter of the at least one set of first power control parameters.

[0053] Further optionally, in an embodiment of the present application, the at least one set of first power control parameters includes open loop power control parameters, and the above step 203 may include the following step 203a:

[0054] Step 203a: The UE determines a target open loop power control parameter group from a power control parameter set configured by higher layer signaling, the power control parameter set includes one group or multiple groups of open loop power control parameters, the target open loop power control parameter group belongs to the power control parameter set, the target open loop control parameter group includes at least one set of first power control parameters, and the target power control parameter is a power control parameter of the at least one set of first power control parameters.

[0055] Illustratively, one target open-loop control parameter group includes a target reception power P0 and a path loss compensation factor, or one or more target reception powers P0. It should be noted that one target open-loop control parameter group may include one P0 or may include two P0.

[0056] Exemplarily, when the DCI does not include an SRI field, the open-loop power control parameters of the one or more sets of first power parameters may be obtained from one or more sets of open-loop power control parameters (e.g., P0-PUSCH-AlphaSet) in a power control parameter set (e.g., P0-AlphaSets).

[0057] Exemplarily, the target open loop power control parameter group is: a position of the target open loop power control parameter group in the power control parameter set is determined based on a second offset value; The target open loop power control parameter group is an open loop power control parameter group corresponding to a group index in a power control parameter set that satisfies a first condition.

[0058] Here, the second offset value is the second offset value being configured by higher layer signaling; and the second offset value being an integer; and the second offset value being associated with an SRS resource set that includes at least one of the target resources.

[0059] Exemplarily, the positions of the one or more P0-PUSCH-AlphaSets in the p0-AlphaSets set may be 1, 1+offset1, 1+offset2, etc., respectively, where offset1, offset2...offset K are configured by higher layer signaling and are associated with SRS resource sets.

[0060] Further optionally, in an embodiment of the present application, the at least one set of first power control parameters comprises parameters indicative of at least one set of path loss reference signals, the parameters of the at least one set of path loss reference signals being: An index of a path loss reference signal configured by a physical uplink control channel (PUCCH) resource; one or more sets of path loss reference signals indexed by consecutive indexes starting from a first predefined index (e.g., index 0); and a reference signal in a Transmission Configuration Indicator (TCI) state of a plurality of CORESETs indicated by a plurality of consecutive indexes starting from a second preset index (e.g., a lowest index, a specific index, etc.); As an alternative solution, the target power control parameters include at least one of a power control parameter of the at least one first set of power control parameters and a power control parameter of the at least one second set of power control parameters. Illustratively, the first set of power control parameters may be referred to as SRI-PUSCH-PowerControl, and the second set of power control parameters may be referred to as a PUSCH target receive power group (P0-PUSCH-Set-r16), where P0-PUSCH-Set-r16 includes a target receive power P0.

[0061] Optionally, in an embodiment of the present application, after the above step 202, the power control method according to the embodiment of the present application may include the following step 204.

[0062] Step 204: The UE determines at least one set of second power control parameters from the multiple sets of second power control parameters configured by higher layer signaling.

[0063] Further optionally, in an embodiment of the present application, if the DCI does not include an SRI field, the set of second power control parameters includes at least two second power control parameters.

[0064] Further optionally, in an embodiment of the present application, the set of second power control parameters corresponds to an index, and the at least one set of second power control parameters is at least one set of second power control parameters corresponding to a target index among the plurality of sets of second power control parameters, where the target index is obtained based on a third offset value from a preset index.

[0065] Exemplarily, the third offset value is: the third offset value being configured by higher layer signaling; and the third offset value being an integer; and the third offset value being associated with an SRS resource set that includes at least one of the target resources.

[0066] Exemplarily, the one or more sets of P0-PUSCH-Set-r16 may be P0-PUSCH-Set-r16 corresponding to indices such as index a, index (a+offset1), index (a+offset2), ..., index (a+offsetH), etc., where offset1, offset2 ... offsetH are configured by higher layer signaling and are associated with SRS resource sets. In one example, the index a may be a minimum index.

[0067] Further optionally, in an embodiment of the present application, the target power control parameter includes a target third power control parameter (eg, the target received power P0), and the step 202 may include the following step 202b.

[0068] Step 202b: If the at least one set of first power control parameters and the at least one set of second power control parameters both include a third power control parameter, the UE determines a target third power control parameter from the at least one set of first power control parameters and the at least one set of second power control parameters based on a field value of an open loop power control parameter set indication field in the DCI.

[0069] Exemplarily, the open-loop power control parameter set indication field may be referred to as an OLPC (Open-loop power control parameter set indication) field. As can be understood, the OLPC field in the DCI and the SRI field jointly indicate at least one set of second power control parameters for the UE. For example, the UE receives higher layer signaling and obtains that the size of the number of bits of the OLPC field of DCI format0_1 and DCI format0_2 for scheduling the PUSCH is 1 bit or 2 bits.

[0070] Illustratively, the OLPC field is used to indicate the source of the target third power control parameter (ie, P0).

[0071] Illustratively, when the open loop power control parameter set indication field includes one valid bit, the field value of the OLPC field is used to indicate whether the target third power control parameter is from at least one set of first power control parameters or from at least one set of second power control parameters.

[0072] Example 1: For a scenario in which the OLPC field is one valid bit (i.e., 1 bit), when the OLPC field takes a "0", it indicates that P0 of one or more sets of PUSCH transmissions takes P0 in one or more SRI-PUSCH-PowerControls, respectively, indicated by the SRI field, or when the OLPC field takes a "1", it indicates that P0 of one or more sets of PUSCH transmissions takes P0 in one or more P0-PUSCH-Set-r16s, respectively, indicated by the SRI field.

[0073] Exemplarily, when the open loop power control parameter set indication field includes X valid bits, each group of valid bits in the open loop power control parameter set indication field corresponds to one of the target resources, and the X valid bits include at least one group of valid bits, where X is an integer greater than 1. Furthermore, a value of any one group of valid bits in the open loop power control parameter set indication field is used to indicate a target third power control parameter associated with a target resource corresponding to the any one group of valid bits.

[0074] Example 2: For a scenario in which the DCI includes an SRI field and the OLPC field includes two significant bits, assuming that the most significant bit is associated with a first SRS resource and the least significant bit is associated with a second SRS resource, the source indication scheme of the above P0 is as shown in Table 1 below.

[0075] [Table 1]

[0076] It should be noted that if the SRI field indicates only one SRS resource or one SRS resource group, this OLPC field is used to indicate the source of the P0 validity bit corresponding to this SRS resource or SRS resource group.

[0077] Example 3: For a scenario in which the DCI does not include an SRI field and the OLPC field includes four useful bits, the first two useful bits are associated with a first SRS resource, the next two useful bits are associated with a second SRS resource, and each set of second power control parameters includes two second power control parameters (i.e., P0-1 and P0-2), the indication of the source of P0 is as shown in Table 2 below.

[0078] [Table 2]

[0079] Further optionally, in an embodiment of the present application, the above step 204 may include the following step 204a.

[0080] Step 204a: If the DCI includes an SRI field, the UE receives at least one second list of list According to the arrangement, the at least one second list and determining at least one set of second power control parameters corresponding to

[0081] Here, the second list has a mapping relationship with the second value list and the second value includes one of a field value of an SRI field included in the DCI and a value obtained after superimposing a fourth offset value, which is different from one another, on the field value of an SRI field included in the DCI.

[0082] Exemplarily, the fourth offset value is the fourth offset value being configured by higher layer signaling; and the fourth offset value being an integer; and the fourth offset value being associated with an SRS resource set that includes at least one of the target resources.

[0083] Exemplarily, the SRI field included in the DCI corresponds to at least one field value, and the one field value corresponds to at least one second list There is a mapping relationship.

[0084] Illustratively, the second list In one example, the UE receives higher layer signaling and identifies one or more sets of P0-PUSCH-SetList-r16. list Get the placement. list The configuration is used to indicate that the one or more sets of P0-PUSCH-SetList-r16 are respectively associated with multiple SRS resource sets, each set of P0-PUSCH-SetList-r16 includes multiple sets of P0-PUSCH-Set-r16, and each set of P0-PUSCH-Set-r16 includes one P0-PUSCH-r16 (P0).

[0085] Exemplarily, the SRI fields in the DCI may be mapped to different P0-PUSCH-SetList-r16s to obtain multiple sets of P0-PUSCH-Set-r16s.

[0086] For example, the UE receives higher layer signaling, obtains a set of P0-PUSCH-SetList-r16 configurations, obtains multiple fourth offset values, and superimposes different fourth offset values ​​on the SRI values ​​of the SRI field, which are then mapped to a set of P0-PUSCH-SetList-r16, respectively, to obtain multiple sets of P0-PUSCH-Set-r16.

[0087] Example 3: First, the UE receives higher layer signaling, which configures two SRS resource sets for codebook transmission, two sri-PUSCH-MappingToAddModLists are associated with the two SRS resource sets, and two P0-PUSCH-SetList-r16s are associated with the SRS resource sets. The UE also receives DCI for scheduling PUSCH transmission, and the SRI field of the DCI indicates two SRS resources from different SRS resource sets for PUSCH transmission. At this time, the value of the SRI field of the DCI is mapped to two sri-PUSCH-MappingToAddModLists, respectively, to obtain two SRI-PUSCH-PowerControls (including P0_a and P0_b, respectively) associated with the two SRS resources. Then, the value of the SRI field of the DCI is mapped to two P0-PUSCH-SetList-r16, respectively, to obtain two P0-PUSCH-Set-r16 (containing P0_c and P0_d, respectively) associated with the two SRS resources.

[0088] Next, when the size of the OLPC field configured by higher layer signaling is 1 bit, "0" indicates that the two P0s of the two sets of power control parameters are equal to P0_a and P0_b in the two SRI-PUSCH-PowerControls, respectively, and "1" indicates that the two P0s of the two sets of power control parameters are P0_c and P0_d in the two P0-PUSCH-SetList-r16s.

[0089] If the size of the OLPC field configured by higher layer signaling is 2 bits, the most significant bit is associated with the first SRS resource, and the least significant bit is associated with the second SRS resource, the interpretation of the OLPC field value is as shown in Table 3 below.

[0090] [Table 3]

[0091] As an alternative solution, at least one time-frequency resource information of the PUSCH transmission corresponds to at least one set of power control parameters.

[0092] Here, the time-frequency resource information is At least one transmission occasion of the PUSCH; The time-frequency resource of each frequency hopping of the PUSCH; A plurality of time domain resources in a first transmission occasion of the PUSCH, one time domain resource being used to indicate one of a plurality of time domain resources including a plurality of consecutive Orthogonal frequency division multiplex (OFDM) symbols.

[0093] Wherein, the first transmission occasion is one of the at least one transmission occasion, and the target power control parameter includes a power control parameter of the at least one set of power control parameters. It should be noted that the power control parameter may be a power control parameter of the at least one set of first power control parameters, or may be a power control parameter of the at least one set of second power control parameters, and the embodiment of the present application is not limited thereto.

[0094] Exemplarily, the at least one transmission occasion may be at least one repeated transmission occasion of a PUSCH, specifically, one repeated transmission occasion of a PUSCH adopts a set of power control parameters to calculate the launch power, where the repeated transmission occasion and the power control parameters are associated with the same SRS resource or SRS resource group.

[0095] Further optionally, in the embodiment of the present application, after the above step 202, the power control method according to the embodiment of the present application may further include the following steps 205a and 205b.

[0096] Step 205a: The UE performs K frequency hopping for the PUSCH, where each frequency hopping of the PUSCH corresponds to one set of power control parameters, where K is an integer equal to or greater than 1.

[0097] Step 205b: In the process of each frequency hopping of the PUSCH, the UE adjusts the transmission power of the PUSCH according to the power control parameter corresponding to each frequency hopping respectively.

[0098] Further optionally, in the embodiment of the present application, each frequency hopping of the PUSCH is Different frequency hopping points corresponding to the transmission occasions of the PUSCH are associated with different target resources; Each frequency hopping point and its corresponding power control parameter satisfy one of the following: the associated target resource is the same.

[0099] Exemplarily, one hop (frequency hopping) of the PUSCH employs one set of power control parameters to calculate the launch power (i.e., the power adjustment of the PUSCH is performed based on one hop), where different hops corresponding to the PUSCH transmission occasions are associated with different SRS resources or SRS resource groups, or the PUSCH hop and the power control parameters corresponding to the hops are associated with the same SRS resource or SRS resource group.

[0100] Further optionally, in an embodiment of the present application, a transmission occasion corresponds to at least one set of power control parameters.

[0101] Further optionally, in an embodiment of the present application, when the first transmission occasion corresponds to at least two sets of power control parameters, each of the time domain resources in the first transmission occasion corresponds to one set of power control parameters. In one example, the target resources associated with the consecutive OFDM symbols are the same or the target resources associated with the consecutive OFDM symbols are the same as the target resources associated with the power control parameters corresponding to the consecutive OFDM symbols.

[0102] Exemplarily, if the repetition number of the PUSCH is 1, the PUSCH repetition occasion adopts at least one set of first power control parameters or at least one set of second power control parameters indicated by the SRI field.

[0103] Exemplarily, consecutive OFDM symbols in one transmission occasion of the PUSCH may adopt one set of power control parameters to calculate the emission power (i.e., the power adjustment may be performed based on consecutive OFDM symbols having the same spatial relationship). It should be noted that the SRS resource or SRS resource group associated with the consecutive OFDM symbols is the same (i.e., the emission beam is the same), and the consecutive OFDM symbols and the power control parameters corresponding to the consecutive OFDM symbols are associated with the same SRS resource or SRS resource group.

[0104] In one example, when the number of repeated transmissions of a PUSCH is 1, if the transmission occasion of this PUSCH adopts multiple sets of power control parameters, the first half of the OFDM symbols adopt one set of power control parameters, and the second half of the OFDM symbols adopt another set of power control parameters.

[0105] For example, when the number of repetitions of a PUSCH is 1, if a code point indicated by the SRI of a DCI scheduling the PUSCH is associated with two SRS resources belonging to different SRS resource sets, the first N / 2 symbols of the PUSCH transmission occasion are transmitted adopting the same spatial relationship as the first SRS resource in the code point, and the remaining NN / 2 symbols are transmitted adopting the same spatial relationship as the second SRS resource in the code point. In this case, the SRI field is mapped to two sri-PUSCH-MappingToAddModLists to obtain two sets of power control parameter groups SRI-PUSCH-PowerControl. Here, the emission power adopted by the first N / 2 symbols of the PUSCH transmission occasion is calculated by the power control parameters mapped on the PUSCH-MappingToAddModList associated with the first SRS resource set, and the remaining NN / 2 emission powers are calculated by the power control parameters mapped on the PUSCH-MappingToAddModList associated with the second SRS resource set.

[0106] Exemplarily, if the number of multiple transmissions of a PUSCH is greater than one, one transmission occasion of the PUSCH adopts one set of power control parameters.
