Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a method, device and terminal for determining power control PC parameters. Background Technology

[0002] The significance of power control (PC) in current technology includes: maintaining power (adjusting power according to the distance between the terminal and the base station to ensure that the power of the signal reaching the base station is close); improving performance (dynamically adjusting power according to channel changes to achieve precise and fast power adjustment); and reducing interference (reducing power leakage from adjacent channels, reducing interference between users and between cells, and extending battery life).

[0003] The power control is divided as follows:

[0004] Downlink power control mainly relies on network-side configuration and implementation;

[0005] Uplink power control mainly includes: PCs for the Physical Uplink Shared Channel (PUSCH), PCs for the Physical Uplink Control Channel (PUCCH), PCs for the Sounding Reference Signal (SRS), and PCs for the Physical Random Access Channel (PRACH).

[0006] It also includes: Power Headroom Report (PHR), which mainly assists base station scheduling; and Power Scaling / Sharing, whose main purpose is to share power and ensure the transmission of higher priority cells / channels.

[0007] On the one hand, 5G introduces a new unified Transmission Configuration Indicator (TCI) architecture, also known as the unified TCI framework. This means that the same beam indicated by the Media Access Control Element (MAC CE) and / or Downlink Control Information (DCI) can be used for multiple channel transmissions; this beam can also be called a common beam. The unified TCI framework includes two modes: joint TCI and separate TCI, configured by the network's RRC signaling. Specifically, the joint TCI state indication indicates that a particular TCI state is used for both uplink and downlink transmission simultaneously; the separate TCI state indication indicates that a particular TCI state is used for either uplink or downlink transmission.

[0008] On the other hand, 5G introduces multi-transmitter-receiver node (multi-TRP, or MTRP) transmission, and the control signaling is divided into two cases: single DCI scheduling and multi-DCI scheduling.

[0009] Multi-DCI (mDCI) scheduling: Each TRP sends its own PDCCH, and each PDCCH schedules its own PDSCH. At this time, the network configures multiple control resource sets (CORESET) for the UE and associates them with different RRC parameters CORESET pool index (CORESETPoolIndex), corresponding to different TRPs.

[0010] Single DCI (sDCI) scheduling: One TRP sends a PDCCH to schedule one PDSCH. In this case, multiple CORESETs configured by the network for the UE cannot be associated with different CORESETPoolIndexes. MACCE activates a maximum of 8 codepoints, with at least one codepoint corresponding to two TCI states. When a codepoint indicated by a TCI field in a DCI corresponds to two TCI states and indicates that one of the TCI states contains "QCL-TypeD", it means that the PDSCH scheduling originates from two TRPs.

[0011] However, the unified TCI framework is currently only applied to single TRP scenarios, and there is no solution for determining uplink channel power control parameters when applying the unified TCI framework in multi-TRP scenarios. Summary of the Invention

[0054] The method for determining power control PC parameters provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0055] Please see Figure 2 , Figure 2 This is a flowchart illustrating the steps of a method for determining power control PC parameters provided in an embodiment of this application. The method for determining PC parameters includes:

[0056] Step 201: The terminal receives common beam information indicated by the network-side device. The common beam information includes: N joint transmission configuration indication (TCI) status information or N independent TCI status information, where N is an integer greater than or equal to 1.

[0057] In this step, the N joint TCI status information can be understood as N TCI status information used simultaneously for uplink and downlink transmission. The N independent TCI status information can be understood as N TCI status information used for uplink transmission, or N TCI status information used for downlink transmission, or N1 TCI status information used for uplink transmission and N2 TCI status information used for downlink transmission, where N1 + N2 equals N. It should be noted that the "TCI status information" mentioned in this embodiment can be any one of the aforementioned N joint TCI status information, or any one of the aforementioned N independent TCI status information; no specific limitation is made here.

[0058] Step 202: If the TCI status information is associated with or contains PC parameters, the terminal determines that the PC parameters of the uplink channel using the TCI status information are the PC parameters associated with or contained in the TCI status information; and / or, if the TCI status information is not associated with or does not contain PC parameters, the terminal determines the PC parameters of the uplink channel using the TCI status information based on the target parameters.

[0059] It should be noted that the "PC parameters" mentioned in the embodiments of this application as "the case where TCI status information is associated with or contains PC parameters" and "the case where TCI status information is not associated with or contains PC parameters" can specifically refer to a set of PC parameters, or a portion of PC parameters from a set of PC parameters. Specifically, a set of PC parameters includes: a path loss estimation reference signal and / or a parameter set (setting), wherein the parameter set includes at least one of: an open-loop receiver power target value P0, a partial path loss compensation factor α, and a closed-loop power control index CLI.

[0060] If the PC parameters are a subset of a set of PC parameters, for example, if the TCI status information is associated with or contains a first subset of PC parameters from a set of PC parameters (the TCI status information is not associated with or contains a second subset of PC parameters from that set of PC parameters), then the first subset of PC parameters of the uplink channel using the TCI status information is the first subset of PC parameters associated with or contained in the TCI status information; the second subset of PC parameters of the uplink channel using the TCI status information is determined by the terminal based on the target parameters.

[0061] The target parameter includes at least one of the following:

[0062] The uplink channel configuration information includes PC parameters;

[0063] The PC parameters associated with the uplink channel;

[0064] Default PC parameters for network configuration;

[0065] The default PC parameters agreed upon in the protocol;

[0066] The spatial relationship information configured on the BWP, which contains the frequency band, carrier, or bandwidth portion of the uplink channel, includes PC parameters.

[0067] The PC parameters indicating the downlink control information for scheduling the uplink channel.

[0068] It should be noted that when N is greater than 1, all N TCI status information can be associated with or contain PC parameters, or none of the N TCI status information can be associated with or contain PC parameters, or some of the N TCI status information can be associated with or contain PC parameters, while some of the N TCI status information can not be associated with or contain PC parameters.

[0069] Optionally, if N is greater than 1, N can be understood as the number of TRPs. For example, if N equals 2, the multiple TCI status information are the TCI status information corresponding to each TRP. If N equals 1, the single TCI status information is the TCI status information of a specific TRP among the multiple TRPs, or it is the common TCI status information of all TRPs.

[0070] It should be noted that in the multi-TRP scenario applied in the embodiments of this application, for the case where N equals 1, there are the following two situations:

[0071] Scenario 1: In the case of multiple DCI scheduling, the terminal can determine that it is in the multiple DCI mode of the multiple TRP scenario based on the multiple different TRP ID information configured by the network (such as the RRC parameter CORESETPoolIndex). In this scenario, the terminal can also determine that the scheduled channel corresponds to a certain TRP based on the received DCI. Specifically, the DCI will indicate a TCI status information, which can be used to determine that the scheduled channel corresponds to a certain TRP among the multiple TRPs (wherein, the uplink channel using the TCI status information can be understood as the uplink channel of the TRP corresponding to the TCI status information).

[0072] Scenario 2: In the case of single DCI scheduling, the terminal can indirectly determine whether it is in a multi-TRP scenario based on the network configuration information, such as the number of TCI states corresponding to each code point in the code points activated by MAC CE. In this scenario, the terminal determines that the scheduled channel corresponds to one or more TRPs based on the TCI states corresponding to the code points indicated by the received DCI. When the code point indicated by the DCI corresponds to one TCI state, this one TCI state can be used to determine that the uplink channel scheduled by the DCI applies this one TCI state information and corresponds to one of the multiple TRPs.

[0073] As an optional embodiment, the uplink channel mentioned in this application includes: Physical Uplink Control Channel (PUCCH) and / or Physical Uplink Shared Channel (PUSCH). PUSCH and PUCCH can be at least one of the following:

[0074] Preset PDCCH scheduling or associated PUSCH and PUCCH

[0075] UE-specific PUSCH or PUCCH;

[0076] Dynamically scheduled PUSCH;

[0077] Configure granted PUSCH;

[0078] The preset PDCCH can be: all PDCCH, or, PDCCH on a UE-specific CORESET, or, PDCCH on a CORESET associated only with a user-specific search space USS, or, PDCCH on a CORESET associated with both USS and the common search space CSS, or, PDCCH on a CORESET other than CORESET#0.

[0079] In at least one embodiment of this application, the PC parameters of the uplink channel can also be referred to as a set of PC parameters of the uplink channel, wherein the set of PC parameters includes: a path loss estimation reference signal and / or a parameter set, wherein the parameter set includes at least one of: an open-loop receiver power target value P0, a partial path loss compensation factor α, and a closed-loop power control index CLI.

[0080] Optionally, in this embodiment of the application, if the TCI status information indicated by the network is associated with or contains PC parameters, then the PUCCH power control corresponding to the TCI status information (such as corresponding to a certain TRP ID) uses the PC parameters associated with or contained in the TCI status information; or, the PUSCH power control corresponding to the TCI status information (such as corresponding to a certain TRP ID) uses the PC parameters associated with or contained in the TCI status information.

[0081] As an optional embodiment, if the TCI status information is associated with or includes PC parameters, the method further includes:

[0082] If spatial relation information is configured on the frequency band, carrier, or BWP where the uplink channel is located, and the spatial relation information includes PC parameters, the terminal ignores the PC parameters included in the spatial relation information; it can also be said that the terminal preferentially uses the PC parameters associated with or included in the TCI status information.

[0083] For example, PUCCH spatial relationship information can be configured simultaneously on a frequency band, carrier, or BWP that has been configured with unified TCI. This PUCCH spatial relationship information includes PC parameters, and the terminal preferentially uses the PC parameters associated with or contained in the TCI status information indicated by the network.

[0084] As another optional embodiment, if the TCI status information is associated with or includes PC parameters, the method further includes:

[0085] When the uplink channel using the TCI status information is located in the frequency range FR1, the terminal ignores the Quasi-Co-location Type D Reference Signal (QCL-Type D RS) in the TCI status information, or the TCI status information does not contain the Quasi-Co-location Type D Reference Signal (QCL-Type D RS). In other words, for low-frequency uplink channels, it is generally not necessary to use beam information similar to that used in high-frequency bands; therefore, the QCL-Type DRS used to determine beam information in the TCI status information is useless and can be ignored.

[0086] For example, for FR1 PUCCH, the terminal ignores QCL-TypeD RS in the TCI status information.

[0087] For example, for FRI PUSCH, the terminal ignores the QCL-TypeD RS in the TCI status information, or the TCI status information does not contain QCL-TypeD RS.

[0088] In at least one embodiment of this application, when the target parameter is a PC parameter included in the configuration information of the uplink channel, before the terminal determines the PC parameter of the uplink channel applying the TCI state information based on the target parameter, the method further includes:

[0089] The terminal receives the configuration information of the uplink channel, which includes at least one set of PC parameters. For example, the configuration information of the uplink channel includes: configuration information of PUCCH, and / or configuration information of PUSCH, without specific limitations here.

[0090] Accordingly, the terminal determines the PC parameters of the uplink channel using the TCI state information based on the target parameters, including:

[0091] When the uplink channel configuration information includes a set of PC parameters, the terminal determines that the PC parameters of the uplink channel applying the TCI status information are the set of PC parameters.

[0092] or,

[0093] When the uplink channel configuration information includes two or more sets of PC parameters, the terminal determines the PC parameters of the uplink channel that apply the TCI status information according to the first correspondence: wherein the first correspondence includes at least one of the following: the correspondence between the order of PC parameters and the identifier of TCI status information, the correspondence between the order of PC parameters and the TRP identifier corresponding to the uplink channel, the correspondence between the position of PC parameters and the identifier of TCI status information, the correspondence between the position of PC parameters and the TRP identifier corresponding to the uplink channel, the correspondence between the identifier of PC parameters and the identifier of TCI status information, and the correspondence between the identifier of PC parameters and the TRP identifier corresponding to the uplink channel.

[0094] For example, when N equals 1, the uplink channel configuration information includes two sets of PC parameters. The terminal uses the set of PC parameters corresponding to the TCI status information or the preset TRP. The correspondence can be based on the order / position / ID of the PC parameters and their correspondence with the TCI status ID or TRP ID. The preset TRP ID is the TRP ID associated with the PUCCH or PUSCH, or the TRP ID corresponding to the PDCCH that schedules or triggers the PUCCH. The TRP corresponding to the uplink channel can be understood as: the TRP associated with the uplink channel; or it can be understood as: the TRP corresponding to the downlink control channel that schedules or triggers the uplink channel. For multi-DCI scenarios, the TRP can be characterized using the RRC parameter CORESETPoolIndex. For single-DCI scenarios, since the network may not configure the RRC parameter CORESETPoolIndex, the channel group can be used to indirectly characterize the TRP.

[0095] For example, if the configuration information of PUCCH or PUSCH includes a set of PC parameters, then the PC parameters of PUCCH or PUSCH that apply the TCI status information are the set of PC parameters in that configuration information.

[0096] For example, if the configuration information of PUCCH or PUSCH includes two or more sets of PC parameters, then the PC parameters of PUCCH or PUSCH that apply the TCI status information are: a set of PC parameters corresponding to the TCI status information.

[0097] For example, if multiple TCI status messages are not associated with or contain PC parameters, and the configuration information includes multiple sets of PC parameters, then one TCI status message corresponds to one set of PC parameters in the configuration information; or, if multiple TCI status messages are not associated with or contain PC parameters, and the configuration information includes one set of PC parameters, then multiple TCI status messages correspond to one set of PC parameters in the configuration information; or, if one TCI status message is not associated with or contains PC parameters, and the configuration information includes multiple sets of PC parameters, then that TCI status message corresponds to a default set of PC parameters in the configuration information. The position, order, or ID of the default PC parameters can be configured by the network or pre-defined.

[0098] Optionally, if the configuration information of PUCCH or PUSCH includes two or more sets of PC parameters, only the CLI differs among the two or more sets of PC parameters.

[0099] In at least one embodiment of this application, when the target parameter is an uplink channel associated PC parameter, before the terminal determines the uplink channel PC parameter for which the TCI state information is applied based on the target parameter, the method further includes:

[0100] The terminal receives a first signaling message, which is used to configure or indicate at least one set of PC parameters associated with the uplink channel. For example, the first signaling message is RRC signaling or MAC CE signaling.

[0101] Optionally, the PC parameters associated with the uplink channel can also be referred to as: PC parameters associated with uplink channel resources.

[0102] For example, the network uses RRC signaling to configure at least one set of PC parameters associated with the PUCCH resource; or, the network uses MAC CE to indicate at least one set of PC parameters associated with the PUCCH resource.

[0103] For example, when N equals 1, the network uses MAC CE to instruct the PUCCH resource to associate two sets of PC parameters, and the terminal uses the set of PC parameters corresponding to the TCI status information or the preset TRP. The correspondence can be based on the order / position / ID of the PC parameters and their correspondence with the TCI status ID or TRP ID. The preset TRP ID is the TRP ID associated with the PUCCH or PUSCH, or the TRP ID corresponding to the PDCCH that schedules or triggers the PUCCH.

[0104] As an optional embodiment, before the terminal receives the first signaling, the method further includes:

[0105] The terminal receives a second signaling message, which is used to configure a first set of PC parameters for the uplink channel. The first set of PC parameters includes multiple sets of PC parameters; for example, the second signaling message is an RRC signaling message.

[0106] The first signaling is used to indicate that at least one set of PC parameters in the first PC parameter set is associated with the uplink channel.

[0107] For example, the network uses RRC signaling to configure a first set of PC parameters for PUCCH, and the network uses MAC CE to instruct PUCCH resources to associate at least one set of PC parameters from the first set of PC parameters for PUCCH power control.

[0108] Accordingly, the terminal determines the PC parameters of the uplink channel using the TCI state information based on the target parameters, including:

[0109] If the first signaling configures or indicates a set of PC parameters associated with the uplink channel, the terminal determines that the PC parameters of the uplink channel for which the TCI state information is applied are the set of PC parameters.

[0110] or,

[0111] When the first signaling configures or indicates two or more sets of PC parameters associated with the uplink channel, the terminal determines the PC parameters of the uplink channel applying the TCI status information according to a first correspondence: wherein the first correspondence includes at least one of the following: a correspondence between the order of PC parameters and the identifier of the TCI status information, a correspondence between the order of PC parameters and the TRP identifier corresponding to the uplink channel, a correspondence between the position of PC parameters and the identifier of the TCI status information, a correspondence between the position of PC parameters and the TRP identifier corresponding to the uplink channel, a correspondence between the identifier of PC parameters and the identifier of the TCI status information, and a correspondence between the identifier of PC parameters and the TRP identifier corresponding to the uplink channel.

[0112] The TRP corresponding to the uplink channel can be understood as: the TRP associated with the uplink channel; or it can be understood as: the TRP corresponding to the downlink control channel that schedules or triggers the uplink channel.

[0113] For example, if the first signaling configures or indicates a set of PC parameters, then the PC parameters of the PUCCH or PUSCH that apply the TCI status information are that set of PC parameters.

[0114] For example, if the first signaling includes two or more sets of PC parameters, then the PC parameters of the PUCCH or PUSCH that apply the TCI status information are: a set of PC parameters corresponding to the TCI status information.

[0115] For example, if multiple TCI status information is not associated with or contains PC parameters, and the first signaling includes multiple sets of PC parameters, then one TCI status information corresponds to one set of PC parameters in the configuration information; or, if multiple TCI status information is not associated with or contains PC parameters, and the first signaling includes one set of PC parameters, then multiple TCI status information corresponds to one set of PC parameters in the configuration information; or, if one TCI status information is not associated with or contains PC parameters, and the first signaling includes multiple sets of PC parameters, then that TCI status information corresponds to a default set of PC parameters in the first signaling, and the position, order, or ID of the default PC parameters can be configured by the network or pre-defined.

[0116] In at least one embodiment of this application, when the target parameter is the PC parameter of the downlink control information indicating the scheduling of the uplink channel, and the uplink channel is the Physical Uplink Shared Channel (PUSCH), before the terminal determines the PC parameter of the uplink channel applying the TCI state information based on the target parameter, the method further includes:

[0117] The terminal receives a third signaling message, which is used to configure a second set of PC parameters for the PUSCH; the second set of PC parameters includes multiple sets of PC parameters; optionally, the third signaling message is an RRC signaling message.

[0118] The terminal receives downlink control information (DCI) for scheduling the PUSCH. The downlink control information includes a probe reference signal SRS resource indication (SRI) field, which is used to indicate at least one set of PC parameters in the second PC parameter set.

[0119] For example, if the RRC is configured with a second set of PC parameters for PUSCH, and the DCI for scheduling PUSCH contains an SRI field, then the PC parameters in the second set of PC parameters are indirectly indicated through the SRI field.

[0120] Accordingly, the terminal determines the PC parameters of the uplink channel applying the TCI state information based on the target parameters, including:

[0121] The terminal determines that the PC parameters of the uplink channel using the TCI status information are the PC parameters indicated by the SRS resource indication field associated with the TCI status information.

[0122] Optionally, if multiple TCI status information are not associated or do not contain PC parameters, the DCI may contain multiple SRI fields, each SRI field indicating a set of PC parameters; or, the DCI may contain one SRI field, which indicates multiple sets of PC parameters.

[0123] Optionally, if a TCI status message is not associated with or does not contain PC parameters, the DCI contains an SRI field that indicates a set of PC parameters.

[0124] In at least one embodiment of this application, when the target parameter is a default PC parameter agreed upon by the network configuration or protocol, the terminal determines the PC parameter of the uplink channel applying the TCI state information based on the target parameter, including:

[0125] When the default PC parameters are a set of PC parameters, the terminal determines that the PC parameters of the uplink channel applying the TCI status information are the default set of PC parameters.

[0126] or,

[0127] When the default PC parameters include two or more sets of PC parameters, the terminal determines that the PC parameters of the uplink channel for which the TCI status information is applied are the first default PC parameters among the two or more default PC parameters; wherein, the first default PC parameters are pre-agreed default PC parameters.

[0128] For example, when the protocol predefines two sets of default PC parameters for two TCI state information, the first set of default PC parameters may include: P0 is the smallest ID in the P0 set; PLRS is the PLRS with index 0; Close loop index:l=0. The second set of default PC parameters may include: P0 is the second smallest ID in the P0 set; PLRS is the PLRS with index 1; Close loop index:l=1.

[0129] Optionally, if multiple TCI status information are not associated or do not contain PC parameters, these multiple TCI status information can correspond to a set of default PC parameters, or each of the multiple TCI status information can correspond to a set of default PC parameters, without specific limitations here.

[0130] For example, the first set of default PC parameters in the two sets of default PC parameters agreed upon by the network configuration or protocol, or the only set of default PC parameters agreed upon by the network configuration or protocol, may include: P0 is the P0 with the smallest ID in the P0 set; PLRS is the PLRS with index 0; Close loop index:l=0.

[0131] The second set of default PC parameters mentioned above can include: P0 is the second smallest ID in the P0 set; PLRS is the PLRS with index 1; Close loop index: l = 1.

[0132] In at least one embodiment of this application, when the uplink channel is PUSCH and an open-loop power control (OLPC) domain is configured, the PC parameters of the PUSCH include a first P0 and a second P0.

[0133] As an optional embodiment, the method further includes:

[0134] When the PC parameters associated with or included in the TCI status information include the first P0 and the second P0,

[0135] The terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI status information based on the PC parameters associated with or included in the TCI status information.

[0136] For example, the values ​​of the first P0 and the second P0 are determined based on the index size or position; for instance, the larger index is the first P0, and the smaller index is the second P0.

[0137] As another optional embodiment, the method further includes:

[0138] If the PC parameter associated with or included in the TCI status information includes the first P0,

[0139] The terminal determines the value of the first P0 of the PUSCH that applies the TCI status information based on the PC parameters associated with or included in the TCI status information.

[0140] The terminal determines the value of the second P0 of the PUSCH that applies the TCI status information based on the SRS resource indication field contained in the downlink control information of the scheduling PUSCH or a set of default second P0 values ​​associated with the TCI status information.

[0141] Optionally, a set of default values ​​for the second P0 associated with this TCI status information can be configured by the network side or pre-agreed upon.

[0142] Accordingly, before the terminal determines the value of the second P0 of the PUSCH that applies the TCI status information based on the SRS resource indication field included in the downlink control information of the scheduling PUSCH, the method further includes:

[0143] The terminal receives the third PC parameter set of the PUSCH configured by the network.

[0144] The terminal receives downlink control information for scheduling the PUSCH. The downlink control information includes a first detection reference signal (SRS) resource indication field, and the value of the first SRS resource indication field is mapped to a P0 value in the third PC parameter set.

[0145] The terminal determines the second P0 of the PUSCH that applies the TCI status information based on the SRS resource indication field included in the downlink control information of the scheduled PUSCH, including:

[0146] The terminal determines that the value of the second P0 of the PUSCH that applies the TCI status information is one of the P0 values ​​in the third PC parameter set mapped by the first SRS resource indication field associated with the TCI status information.

[0147] For example, if the RRC configures a third PC parameter set for the PUSCH, and the DCI for scheduling the PUSCH includes an SRI field, then a second P0 is indicated through the SRI field. The value of the SRI field is mapped to the third PC parameter set of the PUSCH to obtain the value of the second P0. Optionally, this SRI field is the SRI field associated with the TCI status information.

[0148] As another optional embodiment, the method further includes:

[0149] If the PC parameters associated with or included in the TCI status information do not include the first P0 and the second P0, or if the TCI status information is not associated with or does not include PC parameters.

[0150] The terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI state information based on the SRS resource indication field included in the downlink control information of the scheduling PUSCH.

[0151] Alternatively, the terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI state information based on a set of default first P0 values ​​associated with the TCI state and a set of default second P0 values ​​associated with the TCI state.

[0152] For example, the protocol predefines two default first P0 sets for two TCI states, where the first first P0 set is P0 with the smallest ID in the P0 set; the second first P0 set is P0 with the second smallest ID in the P0 set; the protocol predefines two default second P0 sets for two TCI states, where the first second P0 set is P0 with the smallest ID in the second P0 set; the second second P0 set is P0 with the second smallest ID in the second P0 set, or P0 with the smallest ID in the second second P0 set.

[0153] For example, the protocol defines only one set of default PC parameters: P0 is the P0 with the smallest ID in the P0 set; PLRS is the PLRS with index 0; Close loop index:l = 0.

[0154] The protocol defines only one set of default first P0 and default second P0: First P0: P0 is the P0 with the smallest ID in the set of P0; Second P0: P0 is the P0 with the smallest ID in the set of second P0.

[0155] Accordingly, before the terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI state information based on the SRS resource indication field included in the downlink control information of the scheduling PUSCH, the method further includes:

[0156] The terminal receives the fourth PC parameter set and the fifth PC parameter set of the PUSCH configured by the network.

[0157] The terminal receives downlink control information for scheduling the PUSCH. The downlink control information includes a second SRS resource indication field and a third SRS resource indication field. The value of the second SRS resource indication field is mapped to a P0 value in the fourth PC parameter set, and the value of the third SRS resource indication field is mapped to a P0 value in the fifth PC parameter set.

[0158] The terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI state information based on the SRS resource indication field included in the downlink control information of the scheduling PUSCH, including:

[0159] The terminal determines that the value of the first P0 of the PUSCH that applies the TCI status information is the value of P0 in the fourth PC parameter set mapped to the second SRS resource indication field associated with the TCI status information.

[0160] The terminal determines that the value of the second P0 of the PUSCH that applies the TCI status information is the value of P0 in the fifth PC parameter set mapped to the third SRS resource indication field associated with the TCI status information.

[0161] For example, if RRC is configured with the fourth PC parameter set and the fifth PC parameter set for PUSCH, and the DCI for scheduling PUSCH contains two SRI fields, then the two SRI fields indicate the value of a first P0 and the value of a second P0, respectively.

[0162] Specifically, the value of the second SRI field is mapped to the fourth PC parameter set of PUSCH to obtain the value of the first P0; the value of the third SRI field is mapped to the fifth PC parameter set of PUSCH to obtain the value of the second P0. The second and third SRI fields are SRI fields associated with this TCI state.

[0163] Alternatively, before the terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI status information based on the SRS resource indication field included in the downlink control information of the scheduling PUSCH, the method further includes:

[0164] The terminal receives the sixth PC parameter set and the seventh PC parameter set of the PUSCH configured by the network.

[0165] The terminal receives downlink control information for scheduling the PUSCH. The downlink control information includes a fourth SRS resource indication field. The value of the fourth SRS resource indication field is mapped to a P0 value in the sixth PC parameter set, and the value of the fourth SRS resource indication field is mapped to a P0 value in the seventh PC parameter set.

[0166] The terminal determines the values ​​of the first P0 and the second P0 of the PUSCH that apply the TCI state information based on the SRS resource indication field included in the downlink control information of the scheduling PUSCH, including:

[0167] The terminal determines that the value of the first P0 of the PUSCH that applies the TCI status information is the value of P0 in the sixth PC parameter set that is mapped to the fourth SRS resource indication field associated with the TCI status information.

[0168] The terminal determines that the value of the second P0 of the PUSCH that applies the TCI status information is the value of P0 in the seventh PC parameter set mapped to the fourth SRS resource indication field associated with the TCI status information.

[0169] For example, if RRC is configured with the sixth PC parameter set and the seventh PC parameter set for PUSCH, and the DCI for scheduling PUSCH contains an SRI field, then the SRI field indicates the value of a first P0 and the value of a second P0 respectively.

[0170] Specifically, the value of the fourth SRI field is mapped to the sixth PC parameter set of PUSCH to obtain the value of the first P0; the value of the fourth SRI field is mapped to the seventh PC parameter set of PUSCH to obtain the value of the second P0. The fourth SRI field is the SRI field associated with this TCI state.

[0171] In at least one embodiment of this application, the method further includes:

[0172] The terminal determines the target P0 used by the PUSCH based on the OLPC field included in the downlink control information of the PUSCH scheduling. The target P0 is either the first P0 or the second P0. For example, the OLPC field is 1 bit, where 0 indicates the use of the first P0 and 1 indicates the use of the second P0.

[0173] In summary, in the embodiments of this application, for the scenario of applying a unified TCI architecture in multiple TRPs, after the terminal receives N TCI status information indicated by the network, it determines the PC parameters of the uplink channel applying the TCI status information based on the PC parameters associated with or included in the TCI status information, and / or determines the PC parameters of the uplink channel applying the TCI status information based on the PC parameters included in the target parameters, thereby ensuring the correctness of uplink channel power adjustment and uplink channel transmission performance.
