Description

Method, device and terminal for determining power control PC parameters

Technical Field

The application belongs to the technical field of communication, and particularly relates to a method, a device and a terminal for determining parameters of a Power Control (PC).

Background

The meaning of the Power Control (PC) in the prior art includes: maintaining power (adjusting power according to the distance between a terminal and a base station to ensure that the power of a signal reaching the base station is close); performance is improved (power is dynamically adjusted according to channel variation, and accurate and rapid power adjustment is realized); interference is reduced (adjacent channel power leakage is reduced, inter-user and inter-cell interference is reduced, and battery life is prolonged).

The power control is divided as follows:

the downlink power control mainly depends on the configuration and implementation of a network side;

the uplink power control mainly comprises: PC of physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), PC of physical uplink control channel (Physical Uplink Control Channel, PUCCH), PC of sounding reference signal (Sounding Reference Signal, SRS), PC of physical random access channel (Physical Random Access Channel, PRACH);

further comprises: reporting power headroom (Power Headroom Report, PHR), mainly for secondary base station scheduling; power scaling (Power scaling/sharing) is mainly aimed at sharing Power and guaranteeing higher priority cell/channel transmission.

In one aspect, a new unified transmission configuration indication (Transmission Configuration Indicator, TCI) architecture is introduced in 5G, which may be referred to as unified TCI framework, i.e., the same beam (beam) indicated by the network using the medium access control layer control element (Media Access Control Control Element, MAC CE) and/or downlink control information (Downlink Control Information, DCI) may be used for multiple channel transmissions, which beam may also be referred to as a common beam. The two modes, joint TCI (joint TCI) and independent TCI (separate TCI), included in unified TCI framework are configured by the RRC signaling of the network. The joint TCI status indication specifically includes: indicating a certain TCI state to be used for uplink transmission and downlink transmission simultaneously; the independent TCI status indication specifically includes: indicating a certain TCI state for uplink or downlink transmission.

On the other hand, multi-transmission receiving node (multi-TRP, which may be simply referred to as MTRP) transmission is introduced in 5G, and the aspect of control signaling is divided into two cases of single DCI scheduling and multi-DCI scheduling:

multi-DCI (multi-DCI, which may be abbreviated as mci) scheduling: each TRP transmits a respective PDCCH, each PDCCH scheduling a respective PDSCH, when a plurality of control resource sets (CORESETs) configured by the network for the UE are associated to different RRC parameters CORESET Chi Suoyin (coresetpoolndex), corresponding to different TRPs;

single DCI (single DCI, abbreviated as sdi) scheduling: one PDSCH is scheduled by one TRP transmitted PDCCH, when multiple CORESETs configured by the network for the UE cannot be associated to different coresetpoolndexs. In this case, the MAC CE activates at most 8 code points (codepoints), at least one of which corresponds to two TCI states. When the codebook indicated by TCI field in one DCI corresponds to two TCI states and indicates that one TCI state contains "QCL-type", it means that the scheduled PDSCH comes from two TRPs.

However, in unified TCI framework, currently only applied to a single TRP scenario, there is no scheme for determining the uplink channel power control parameter when unified TCI framework is applied in a multi TRP scenario.

The method for determining the parameters of the power control PC according to the embodiment of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a method for determining a PC parameter of power control according to an embodiment of the present application, where the method for determining a PC parameter includes:

step 201, a terminal receives common beam information indicated by a network side device, where the common beam information includes: n joint transmission configuration indication TCI state information or N independent TCI state information, wherein N is an integer greater than or equal to 1;

in this step, the N pieces of joint TCI status information may be understood as N pieces of TCI status information for uplink and downlink transmissions at the same time. The N independent TCI status information may be understood as N TCI status information for uplink transmission, or N TCI status information for downlink transmission, or N1 TCI status information for uplink transmission and N2 TCI status information for downlink transmission, and n1+n2 is equal to N. It should be noted that, in the embodiment of the present application, the "TCI status information" may be any one of the N pieces of joint TCI status information, or any one of the N pieces of independent TCI status information, which is not specifically limited herein.

Step 202, in the case that the TCI status information is associated with or includes a PC parameter, the terminal determines that the PC parameter of the uplink channel to which the TCI status information is applied is the PC parameter associated with or included in the TCI status information; and/or, under the condition that the TCI state information is not associated with or does not contain PC parameters, the terminal determines the PC parameters of the uplink channel to which the TCI state information is applied according to the target parameters.

It should be noted that, in the case where the "TCI state information is associated with or includes a PC parameter" and the "PC parameter" in the case where the "TCI state information is not associated with or includes a PC parameter" in the embodiment of the present application may specifically be a set of PC parameters or a part of PC parameters in a set of PC parameters. Wherein, a set of PC parameters includes: a path loss estimation reference signal and/or a set of parameters (setting), the set of parameters comprising: at least one of an open loop receiving end power target value P0, a partial path loss compensation factor alpha and a closed loop power control index CLI.

If the PC parameters are part of a set of PC parameters, for example, the TCI status information is associated with or includes a first part of the PC parameters in the set of PC parameters (the TCI status information is not associated with or includes a second part of the PC parameters in the set of PC parameters), then the first part of the PC parameters of the uplink channel applying the TCI status information is the first part of the PC parameters associated with or included in the TCI status information; the second part of the PC parameters of the uplink channel to which the TCI status information is applied is determined by the terminal according to the target parameters.

Wherein the target parameters include at least one of:

the configuration information of the uplink channel comprises PC parameters;

PC parameters associated with the uplink channel;

default PC parameters for network configuration;

default PC parameters agreed by the protocol;

It should be noted that, in the case where N is greater than 1, the N pieces of TCI state information may all be associated with or include a PC parameter, or none of the N pieces of TCI state information may be associated with or include a PC parameter, or some of the N pieces of TCI state information may be associated with or include a PC parameter, and some of the N pieces of TCI state information may not be associated with or include a PC parameter.

Alternatively, in the case where N is greater than 1, N may be understood as the number of TRPs, for example, N is equal to 2, and the plurality of TCI state information are TCI state information respectively corresponding to the TRPs. When N is equal to 1, the 1 TCI state information is TCI state information of one TRP of the plurality of TRPs, or TCI state information common to all TRPs.

It should be noted that, in the multi-TRP scenario applied in the embodiment of the present application, for the case where N is equal to 1, there are the following two cases:

In case 1, in the multi-DCI scheduling case, the terminal can determine, according to the network configured with a plurality of different TRP ID information (e.g., RRC parameter corespoolindex), that in a multi-TRP scenario, in this scenario, the terminal may further determine, according to the received DCI, that the scheduled channel corresponds to a certain TRP, specifically, in the DCI, 1 TCI state information may be indicated, where the 1 TCI state information may be used to determine that the scheduled channel corresponds to a certain TRP in the multi-TRP (where an uplink channel to which the TCI state information is applied may be understood as an uplink channel of the TRP corresponding to the TCI state information).

In case 2, in the single DCI scheduling case, the terminal may determine, indirectly, that the number of TCI states corresponding to each of the code points activated by the MAC CE is in a multi-TRP scenario according to configuration information of the network, where the terminal determines, according to the TCI state corresponding to the code point indicated by the received DCI, that the scheduled channel corresponds to one or more TRPs, and when the code point indicated by the DCI corresponds to 1 TCI state, the 1 TCI state may be used to determine that the 1 TCI state information is applied to the uplink channel scheduled by the DCI and corresponds to one of the multiple TRPs.

As an alternative embodiment, the uplink channel mentioned in the embodiment of the present application includes: a physical uplink control channel PUCCH and/or a physical uplink shared channel PUSCH. PUSCH and PUCCH may be at least one of:

presetting PDCCH scheduling or associated PUSCH and PUCCH

UE-specific PUSCH or PUCCH;

dynamically scheduled PUSCH;

configuring an authorized PUSCH (Configured grant PUSCH);

the preset PDCCH may be: all PDCCHs, or PDCCHs on UE-specific CORESET, or PDCCHs on CORESET associated only with user-specific search space USS, or PDCCHs on CORESET associated USS with common search space CSS, or PDCCHs on CORESET other than CORESET # 0.

In at least one embodiment of the present application, the PC parameters of the uplink channel may also be referred to as a set of PC parameters of the uplink channel, where a set of PC parameters includes: a path loss estimation reference signal and/or a set of parameters (setting), the set of parameters comprising: at least one of an open loop receiving end power target value P0, a partial path loss compensation factor alpha and a closed loop power control index CLI.

Optionally, in the embodiment of the present application, if the TCI state information indicated by the network is associated with or includes a PC parameter, the PUCCH power control (e.g., corresponding to a TRP ID) corresponding to the TCI state information uses the PC parameter associated with or included in the TCI state information; or, the PUSCH power control corresponding to the TCI status information (for example, corresponding to a certain TRP ID) uses the PC parameter associated with or contained in the TCI status information.

As an alternative embodiment, in case the TCI state information is associated with or contains a PC parameter, the method further comprises:

if spatial relationship information (spatial relation info) is configured on a frequency band or carrier or BWP where the uplink channel is located, and the spatial relationship information includes PC parameters, the terminal ignores the PC parameters included in the spatial relationship information; which may also be referred to as the terminal preferably uses the PC parameters associated with or contained in the TCI state information.

For example, PUCCH spatial relationship information including PC parameters is simultaneously configured on a band or carrier or BWP configured with the unified TCI, and the terminal preferentially uses the PC parameters associated with or included in the TCI state information indicated by the network.

As another alternative embodiment, in case the TCI state information is associated with or contains a PC parameter, the method further comprises:

in the case that the uplink channel to which the TCI status information is applied is located in the frequency range FR1, the terminal ignores the reference signal (QCL-type RS) of the quasi co-located type D in the TCI status information, or the TCI status information does not include the reference signal (QCL-type RS) of the quasi co-located type D. That is, it is generally not necessary to use beam information similar to the high band for the uplink channel of the low band, and thus QCL-type RS for determining the beam information in the TCI state information is not useful and can be ignored.

For example, for PUCCH of FR1, the terminal ignores QCL-type RS in TCI state information.

For another example, for PUSCH of the FRI, the terminal ignores QCL-TypeD RS in the TCI state information or does not include QCL-TypeD RS in the TCI state information.

In at least one embodiment of the present application, in the case where 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 to which the TCI status information is applied according to the target parameter, the method further includes:

the terminal receives the configuration information of the uplink channel, wherein the configuration information of the uplink channel comprises at least one set of PC parameters. For example, the configuration information of the uplink channel includes: the configuration information of the PUCCH and/or the configuration information of the PUSCH are not particularly limited herein.

Correspondingly, the determining, by the terminal, the PC parameter of the uplink channel to which the TCI status information is applied according to the target parameter includes:

under the condition that the configuration information of the uplink channel comprises a set of PC parameters, the terminal determines the PC parameters of the uplink channel applying the TCI state information as the set of PC parameters;

or,

under the condition that the configuration information of the uplink channel comprises two or more sets of PC parameters, the terminal determines the PC parameters of the uplink channel applying the TCI state information according to a first corresponding relation: wherein the first correspondence includes at least one of: the corresponding relation between the sequence of the PC parameters and the identifications of the TCI state information, the corresponding relation between the sequence of the PC parameters and the identifications of the TRPs corresponding to the uplink channels, the corresponding relation between the positions of the PC parameters and the identifications of the TCI state information, the corresponding relation between the positions of the PC parameters and the identifications of the TRPs corresponding to the uplink channels, the corresponding relation between the identifications of the PC parameters and the identifications of the TCI state information, and the corresponding relation between the identifications of the PC parameters and the identifications of the TRPs corresponding to the uplink channels.

For example, if N is equal to 1, the configuration information of the uplink channel includes 2 sets of PC parameters, and the terminal uses a set of PC parameters corresponding to the TCI status information or a preset TRP. The correspondence may be a correspondence with TCI status ID or TRP ID according to the order/position/ID of PC parameters or the like. The preset TRP ID is a TRP ID associated with PUCCH or PUSCH, or a TRP ID corresponding to PDCCH that schedules or triggers the PUCCH. The TRP corresponding to the uplink channel can be understood as: TRP associated with uplink channel; it can also be understood that: and scheduling or triggering TRP corresponding to the downlink control channel of the uplink channel. For a multi-DCI scenario, TRP may be characterized using the RRC parameter coresetpoolndex, and for a single-DCI scenario, TRP may be indirectly characterized using a channel group since the network may not configure the RRC parameter coresetpoolndex.

For example, if the configuration information of the PUCCH or PUSCH includes a set of PC parameters, the PC parameters of the PUCCH or PUSCH to which the TCI status information is applied are a set of PC parameters in the configuration information.

For another example, if the configuration information of the PUCCH or PUSCH includes two or more sets of PC parameters, the PC parameters of the PUCCH or PUSCH to which the TCI status information is applied are: and a set of PC parameters corresponding to the TCI state information.

For another example, in the case where none of the plurality of TCI state information is associated with or includes PC parameters, and the configuration information includes a plurality of sets of PC parameters, one TCI state information corresponds to one set of PC parameters in the configuration information; or when none of the plurality of TCI state information is associated with or contains PC parameters and the configuration information comprises one set of PC parameters, the plurality of TCI state information corresponds to one set of PC parameters in the configuration information; or, in the case that one piece of TCI status information is not associated with or does not include a PC parameter, and the configuration information includes multiple sets of PC parameters, the TCI status information corresponds to a set of default PC parameters in the configuration information, and the location, the sequence, or the ID of the default PC parameters may be configured by the network, or may be predetermined in advance.

Alternatively, in the case where two or more sets of PC parameters are included in the configuration information of the PUCCH or PUSCH, only CLI is different in the two or more sets of PC parameters.

In at least one embodiment of the present application, in the case that the target parameter is a PC parameter associated with an uplink channel, before the terminal determines, according to the target parameter, the PC parameter of the uplink channel to which the TCI status information is applied, the method further includes:

the terminal receives a first signaling for configuring or indicating at least one set of PC parameters associated with the uplink channel. For example, the first signaling is RRC signaling, or MAC CE signaling.

Alternatively, the PC parameters associated with the uplink channel may also be referred to as: PC parameters associated with uplink channel resources.

For example, the network configures at least 1 set of PC parameters associated with PUCCH resources using RRC signaling; alternatively, the network indicates at least 1 set of PC parameters associated with PUCCH resources using MAC CE.

For example, in case N is equal to 1, the network uses MAC CE to instruct PUCCH resources to associate 2 sets of PC parameters, and the terminal uses a set of PC parameters corresponding to the TCI status information or a preset TRP. The correspondence may be a correspondence with TCI status ID or TRP ID according to the order/position/ID of PC parameters or the like. The preset TRP ID is a TRP ID associated with PUCCH or PUSCH, or a TRP ID corresponding to PDCCH that schedules or triggers the PUCCH.

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

the terminal receives a second signaling, wherein the second signaling is used for configuring a first PC parameter set for the uplink channel, and the first PC parameter set comprises a plurality of sets of PC parameters; for example, the second signaling is RRC signaling.

Wherein the first signaling is used to indicate that at least one set of PC parameters in the first set of PC parameters is associated with the uplink channel.

For example, the network configures one first set of PC parameters for PUCCH using RRC signaling, and the network uses MAC CE to indicate PUCCH resources to associate at least 1 set of PC parameters in the first set of PC parameters for power control of PUCCH.

in the case that the first signaling configures or indicates a set of PC parameters associated with the uplink channel, the terminal determines the PC parameters of the uplink channel to which the TCI status information is applied as the set of PC parameters;

or,

under the condition that 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 state information according to a first corresponding relation: wherein the first correspondence includes at least one of: the corresponding relation between the sequence of the PC parameters and the identifications of the TCI state information, the corresponding relation between the sequence of the PC parameters and the identifications of the TRPs corresponding to the uplink channels, the corresponding relation between the positions of the PC parameters and the identifications of the TCI state information, the corresponding relation between the positions of the PC parameters and the identifications of the TRPs corresponding to the uplink channels, the corresponding relation between the identifications of the PC parameters and the identifications of the TCI state information, and the corresponding relation between the identifications of the PC parameters and the identifications of the TRPs corresponding to the uplink channels.

The TRP corresponding to the uplink channel can be understood as: TRP associated with uplink channel; it can also be understood that: and scheduling or triggering TRP corresponding to the downlink control channel of the uplink channel.

For example, if the first signaling configures or indicates a set of PC parameters, the PC parameters of PUCCH or PUSCH to which the TCI status information is applied are the set of PC parameters.

For another example, if the first signaling includes two or more sets of PC parameters, the PC parameters of the PUCCH or PUSCH to which the TCI status information is applied are: and a set of PC parameters corresponding to the TCI state information.

For another example, in the case where none of the plurality of TCI state information is associated with or includes PC parameters, and the plurality of sets of PC parameters are included in the first signaling, one TCI state information corresponds to one set of PC parameters in the configuration information; or under the condition that the plurality of TCI state information is not associated with or does not contain the PC parameters, and the first signaling comprises one set of PC parameters, the plurality of TCI state information corresponds to one set of PC parameters in the configuration information; or in the case that one piece of TCI state information is not associated with or does not contain a PC parameter, and the first signaling includes multiple sets of PC parameters, the TCI state information corresponds to a default set of PC parameters in the first signaling, and the position, sequence or ID of the default PC parameters may be configured by the network, or may be predetermined in advance.

In at least one embodiment of the present application, in a case where the target parameter is a PC parameter indicated by downlink control information for scheduling the uplink channel, the uplink channel is a physical uplink shared channel PUSCH, and before the terminal determines the PC parameter of the uplink channel to which the TCI status information is applied according to the target parameter, the method further includes:

The terminal receives a third signaling, wherein the third signaling is used for configuring a second PC parameter set of the PUSCH; the second set of PC parameters includes a plurality of sets of PC parameters; optionally, the third signaling is RRC signaling;

the terminal receives Downlink Control Information (DCI) for scheduling the PUSCH, the downlink control information including a sounding reference signal, SRS, resource indication (SRI) field for indicating at least one set of PC parameters in the second set of PC parameters.

For example, if the RRC configures the second PC parameter set of PUSCH, the DCI scheduling PUSCH includes an SRI field, and the PC parameters in the second PC parameter set are indirectly indicated through the SRI field.

Correspondingly, the terminal determines the PC parameter of the uplink channel to which the TCI state information is applied according to the target parameter, and the method comprises the following steps:

and the terminal determines the PC parameter of the uplink channel applying the TCI state information as the PC parameter indicated by the SRS resource indication domain associated with the TCI state information.

Optionally, if the plurality of TCI status information is not associated with or does not include a PC parameter, the DCI may include a plurality of SRI fields, each SRI field indicating a set of PC parameters; alternatively, 1 SRI field is included in the DCI, which indicates a plurality of sets of PC parameters.

Alternatively, if a TCI status information is not associated with or contains no PC parameters, the DCI contains an SRI field indicating a set of PC parameters.

In at least one embodiment of the present application, in the case that the target parameter is a default PC parameter agreed by a network configuration or a protocol, the determining, by the terminal, the PC parameter of the uplink channel to which the TCI status information is applied according to the target parameter includes:

under the condition that the default PC parameters are a set of PC parameters, the terminal determines that the PC parameters of an uplink channel applying the TCI state information are the default set of PC parameters;

or,

in the case that the default PC parameters include two or more sets of PC parameters, the terminal determines that the PC parameter of the uplink channel to which the TCI status information is applied is a first default PC parameter of the two or more sets of PC parameters; the first default PC parameters are default PC parameters which are agreed in advance.

For example, when the protocol predefines two sets of default PC parameters for two TCI state information, a first set of default PC parameters may include: p0 is P0 of the smallest ID in the P0 set; PLRS is PLRS with index 0; close loop index, l=0. The second set of default PC parameters may include: p0 is P0 of the next-smallest ID in the P0 set; PLRS is PLRS with index 1; close loop index, l=1.

Alternatively, if the plurality of TCI status information is not associated with or does not include a PC parameter, the plurality of TCI status information may correspond to a set of default PC parameters, or each of the plurality of TCI status information corresponds to a set of default PC parameters, which is not specifically limited herein.

For example, the first default set of two default PC parameters of the network configuration or protocol convention, or only 1 default set of PC parameters of the network configuration or protocol convention, may include: p0 is P0 of the smallest ID in the P0 set; PLRS is PLRS with index 0; close loop index, l=0.

The second set of default PC parameters of the two sets of default PC parameters may include: p0 is P0 of the next smallest ID in the P0 set; PLRS is PLRS with index 1; close loop index, l=1.

In at least one embodiment of the present application, in a case where the uplink channel is a 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.

As an alternative embodiment, the method further comprises:

in case the first P0 and the second P0 are included in the PC parameters associated with or included in the TCI state information,

and the terminal determines the value of the first P0 and the value of the second P0 of the PUSCH applying the TCI state information according to the PC parameters associated with or contained in the TCI state information.

For example, the value of the first P0 and the value of the second P0 are determined according to the size or the position of the index, for example, the index is large as the first P0, and the index is small as the second P0.

As another alternative embodiment, the method further comprises:

in case the PC parameter associated or contained by the TCI state information comprises a first P0,

the terminal determines the value of a first P0 of a PUSCH applying the TCI state information according to the PC parameter associated with or contained in the TCI state information;

and the terminal determines the value of the second P0 of the PUSCH applying the TCI state information according to the SRS resource indication field contained in the downlink control information of the scheduled PUSCH or the value of a default set of second P0 related to the TCI state information.

Alternatively, the default set of values of the second P0 associated with the TCI status information may be configured or pre-agreed by the network side.

Correspondingly, before the terminal determines the value of the second P0 of the PUSCH to which the TCI state information is applied according to the SRS resource indication field included in the downlink control information of the scheduled PUSCH, the method further includes:

the terminal receives a third PC parameter set of a PUSCH configured by the network;

The terminal determines a second P0 of the PUSCH to which the TCI state information is applied according to an SRS resource indication field included in the downlink control information of the scheduled PUSCH, including:

and the terminal determines that the value of the second P0 of the PUSCH applying the TCI state information is one P0 value in the third PC parameter set of the first SRS resource indication domain mapping associated with the TCI state information.

For example, if the RRC configures the third PC parameter set of PUSCH, DCI scheduling PUSCH contains an SRI field, 1 second P0 is indicated through the SRI field. And mapping the value of the SRI domain to a third PC parameter set of the PUSCH to obtain the value of the second P0. Optionally, the SRI field is an SRI field associated with the TCI state information.

As another alternative embodiment, the method further comprises:

in case the PC parameters associated or comprised by the TCI state information do not comprise the first P0 and the second P0 or the TCI state information is not associated or does not comprise the PC parameters,

the terminal determines the value of a first P0 and the value of a second P0 of the PUSCH applying the TCI state information according to the SRS resource indication field contained in the downlink control information of the scheduled PUSCH,

or the terminal determines the value of the first P0 and the value of the second P0 of the PUSCH applying the TCI state information according to the value of a default set of first P0 associated with the TCI state and the value of a default set of second P0 associated with the TCI state.

For example, the protocol predefines two default sets of first P0 for two TCI states, where the first set of first P0: p0 is P0 of the smallest ID in the P0 set; second set of first P0: p0 is P0 of the next-smallest ID in the P0 set; the protocol predefines two default sets of second P0 for two TCI states, wherein the first set of second P0: p0 is P0 of the smallest ID in the second P0 set; second set of second P0: p0 is P0 of the next smallest ID in the second P0 set, or P0 is P0 of the smallest ID in the second P0 set.

For another example, the protocol defines only one default set of PC parameters: p0 is P0 of the smallest ID in the P0 set; PLRS is PLRS with index 0; close loop index, l=0.

The protocol defines only a default set of first P0 and default second P0: first P0: p0 is P0 of the smallest ID in the P0 set; second P0: p0 is P0 of the smallest ID in the second P0 set.

Correspondingly, before determining the value of the first P0 and the value of the second P0 of the PUSCH to which the TCI state information is applied according to the SRS resource indication field included in the downlink control information of the scheduled PUSCH, the method further includes:

the terminal receives a fourth PC parameter set and a fifth PC parameter set of a PUSCH configured by a network;

The terminal determines the value of the first P0 and the value of the second P0 of the PUSCH to which the TCI state information is applied according to an SRS resource indication field included in the downlink control information of the scheduled PUSCH, including:

the terminal determines that the value of a first P0 of a PUSCH applying the TCI state information is the value of P0 in the fourth PC parameter set of the second SRS resource indication domain mapping associated with the TCI state information;

and the terminal determines that the value of the second P0 of the PUSCH applying the TCI state information is the value of P0 in the fifth PC parameter set of the third SRS resource indication domain mapping associated with the TCI state information.

For example, if the RRC configures the fourth PC parameter set of PUSCH and the fifth PC parameter set of PUSCH, the DCI scheduling PUSCH includes two SRI fields, and the value of one first P0 and the value of one second P0 are indicated by the two SRI fields, respectively.

The value of the second SRI domain is mapped to a fourth PC parameter set of the PUSCH, and the value of the first P0 is obtained; the value of the third SRI domain is mapped to a fifth PC parameter set of the PUSCH, and the value of the second P0 is obtained. Wherein the second SRI domain and the third SRI domain are SRI domains associated with the TCI state.

Or before determining the value of the first P0 and the value of the second P0 of the PUSCH to which the TCI state information is applied according to the SRS resource indication field included in the downlink control information of the scheduled PUSCH, the method further includes:

The terminal receives a sixth PC parameter set and a seventh PC parameter set of a PUSCH configured by a network;

the terminal receives downlink control information for scheduling the PUSCH, the downlink control information including a fourth SRS resource indication field, the value of the fourth SRS resource indication field being mapped to one P0 value in the sixth PC parameter set, and the value of the fourth SRS resource indication field being mapped to one P0 value in the seventh PC parameter set;

the terminal determines that the value of the second P0 of the PUSCH to which the TCI state information is applied is the value of P0 in the seventh PC parameter set of the fourth SRS resource indication domain map associated with the TCI state information.

For example, if the RRC configures the sixth PC parameter set of PUSCH and the seventh PC parameter set of PUSCH, the DCI scheduling PUSCH includes one SRI field, and the value of one first P0 and the value of one second P0 are indicated through one SRI field, respectively.

The value of the fourth SRI domain is mapped to a sixth PC parameter set of the PUSCH, and the value of the first P0 is obtained; the value of the fourth SRI domain is mapped to a seventh PC parameter set of the PUSCH, and the value of the second P0 is obtained. Wherein the fourth SRI domain is the SRI domain associated with the TCI state.

In at least one embodiment of the application, the method further comprises:

and the terminal determines a target P0 used by the PUSCH according to an OLPC domain contained in downlink control information of the PUSCH, wherein the target P0 is the first P0 or the second P0.
