Fig. 2 is a schematic diagram of a power control method 200 for uplink transmission according to an embodiment of the present disclosure.

210. The terminal device determines the configuration of the power control parameter according to the panel indication information or the channel Sounding Reference Signal (SRS) resource set corresponding to the PUSCH transmission.

Wherein the configuration of the power control parameter is associated with the panel indication information or is associated with the SRS resource set.

220. And the terminal equipment determines the sending power of the PUSCH transmission according to the configuration of the power control parameter.

The main idea of the invention is as follows: because the terminal equipment selects one panel from the plurality of panels to perform PUSCH transmission and adopts different beams when performing PUSCH transmission on different panels, the technical problem of low reliability of power control of uplink transmission caused by performing unified power control on each panel used by the terminal equipment can be solved by performing independent power control on each panel used by the terminal equipment, so that the terminal equipment can perform PUSCH transmission by adopting the optimal transmission power, and the reliability of the power control of the uplink transmission is improved.

Currently, the transmission power of PUSCH transmission can be calculated by the following formula:

where i is the index of a PUSCH transmission, and j is the index of the open loop power control parameter (including the target power P)_{O_PUSCH,b,f,c}(j) And the path loss factor alpha_b,f,c(j))，q _dIs used for measuring road lossIndex of the test signal, f_b,f,c(i, l) is a closed loop power control adjustment factor, where l is an index to the closed loop power control process.

Therefore, the embodiment of the present invention can obtain the configuration of the power control parameter corresponding to each panel by performing independent power control on each panel used by the terminal device.

Specifically, the power control parameter may include, but is not limited to, at least one of a target power, a path loss factor, a path loss measurement reference signal, and a closed-loop power control procedure, which is not particularly limited in this embodiment.

The path loss measurement Reference Signal may only include a Channel State Information-Reference Signal (CSI-RS), or may also include a Synchronization Signal Block (SSB), i.e., SS/PBCH Block, and a Channel State Information-Reference Signal (CSI-RS), which is not particularly limited in this embodiment.

The Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH) together form a Synchronization Signal Block (SSB), i.e., SS/PBCH Block.

Optionally, in a possible implementation manner of this embodiment, the panel indication information adopted by the terminal device may be specifically used to indicate a panel adopted for PUSCH transmission from at least one panel configured by the terminal device.

Generally, the network device configures multiple panels for uplink transmission of the terminal device, and then the network device may send panel indication information to the terminal device to indicate, from the panels, a panel used for PUSCH transmission.

In a specific implementation process, the bit number of the panel indication information and the corresponding relationship between the panel indication information and the panel can be determined according to the capability report of the terminal device. For example, if the terminal device reports the capability of N panels, the bit number of the panel indication information may be log2 (N).

In another specific implementation procedure, the panel indication information may also be used to indicate a target SRS resource set from a plurality of SRS resource sets, where each SRS resource set corresponds to one panel of the terminal device, and the corresponding panel may be indicated by indicating the SRS resource set.

Optionally, in a possible implementation manner of this embodiment, the SRS resource set may include, but is not limited to, multiple SRS resource sets, which is not particularly limited in this embodiment.

In a specific implementation process, the SRS Resource set may include an SRS Resource set where an SRS Resource indicated by an SRS Resource Indicator (SRI) is located.

The SRI may be carried by configuring a high-level signaling transmitted by the PUSCH or scheduling Downlink Control Information (DCI) transmitted by the PUSCH.

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, specifically, the SRI may be carried by an Information Element (IE) in an RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like.

Or, for another example, the higher layer signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the SRI may be carried by adding a new MAC CE message.

In the implementation process, the SRI may not be sent by the high layer signaling or DCI, and may further be predefined by the network device and the terminal device, which is not particularly limited in this embodiment.

In another specific implementation procedure, the set of SRS resources may include a set of SRS resources used for determining a transmission parameter of the PUSCH.

In this implementation process, the transmission parameter may include, but is not limited to, at least one of a number of transmission layers, a precoding matrix, a transmission beam, a Modulation And Coding Scheme (MCS), And a power control parameter, which is not particularly limited in this embodiment.

In another specific implementation procedure, the set of SRS resources may include a set of SRS resources indicated by the panel indication information.

Specifically, the panel indication information may be used to indicate a target SRS resource set from among a plurality of SRS resource sets.

In another specific implementation procedure, the SRS resource sets may include at least two SRS resource sets of the SRS resource sets provided in the foregoing three specific implementation procedures.

Optionally, in a possible implementation manner of this embodiment, before 210, the terminal device may further determine, from at least two SRS resource sets configured for uplink transmission, an SRS resource set corresponding to the PUSCH transmission.

Generally, a network device configures multiple SRS resource sets for uplink transmission of a terminal device, and then the network device may send an indication message to the terminal device to indicate, from the SRS resource sets, the SRS resource sets used for PUSCH transmission.

For example, the panel indication information may be used to indicate, from at least one panel configured by the terminal device, a panel used for PUSCH transmission, or may be used to indicate a target SRS resource set from multiple SRS resource sets, where each SRS resource set corresponds to one panel of the terminal device, and by indicating an SRS resource set, the corresponding panel may be indicated.

Or, for another example, the terminal device may specifically send the SRS resource set indication Information to the terminal device by using one SRS resource set indication Information, and specifically send the SRS resource set indication Information to the terminal device by using a higher layer signaling, a system broadcast message, or Downlink Control Information (DCI).

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, specifically, the SRS Resource set indication Information may be carried by an Information Element (IE) in the RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like.

Or, for another example, the higher layer signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the SRS resource set indication information may be carried by adding a new MAC CE message.

For another example, the SRS resource set indication Information may be carried by an existing Master Information Block (MIB) or a System Information Block (SIB) in the System broadcast message, or new SIBs may be added to carry the SRS resource set indication Information.

In this implementation process, the SRS resource set indication information may not be sent by a high layer signaling, a system broadcast message, or DCI, and may further be pre-agreed by the network device and the terminal device, which is not particularly limited in this embodiment.

Optionally, in a possible implementation manner of this embodiment, before 210, the terminal device may further receive configuration information sent by a network device. The configuration information may be used to indicate configurations of power control parameters respectively associated with different values of the panel indication information; or indicating the configuration of power control parameters respectively associated with different SRS resource sets.

Specifically, the terminal device may specifically receive configuration information sent by the network device through a higher layer signaling, a system broadcast message, or DCI.

For example, the higher layer signaling may be a Radio Resource Control (RRC) message, specifically, the configuration Information may be carried by an Information Element (IE) in the RRC message, and the RRC message may be an RRC message in the prior art, for example, an RRC CONNECTION RECONFIGURATION (RRC CONNECTION RECONFIGURATION) message and the like.

Or, for another example, the higher layer signaling may be a Media Access Control (MAC) Control Element (CE) message, and specifically, the configuration information may be carried by adding a new MAC CE message.

For another example, the configuration Information may be carried by an existing Master Information Block (MIB) or a System Information Block (SIB) in the System broadcast message, or a new SIB may be added to carry the configuration Information.

In this implementation process, the configuration information may not be sent by a high-level signaling, a system broadcast message, or DCI, and may further be pre-agreed by the network device and the terminal device, which is not particularly limited in this embodiment.

In this implementation manner, the configuration information may be implemented in various manners, which is not particularly limited in this embodiment.

For example, if the panel indication information is 1 bit, the configuration information may configure the configuration of two sets of power control parameters, and the values of the panel indication information corresponding to 1 bit are 0 and 1, respectively.

Or, for another example, the network device configures M SRS resource sets for supporting PUSCH transmission in advance for the terminal device, where M is an integer greater than or equal to 1, and parameters of each SRS resource set include configuration of a set of power control parameters for PUSCH transmission. The terminal device may determine, from the M SRS resource sets, an SRS resource set corresponding to the PUSCH transmission, that is, determine a configuration of a corresponding power control parameter.

In addition, if the network device does not send configuration information to configure the panel indication information or SRS resource set corresponding to the PUSCH transmission, the terminal device may adopt the configuration of the first power control parameter configured by the network device as the configuration of the power control parameter for the PUSCH transmission, or may also adopt the configuration of the power control parameter used for the PUSCH transmission that is sent recently, or may also set the value of the configuration of the power control parameter for the PUSCH transmission to zero.

In this way, the terminal device can determine the configuration of different power control parameters for PUSCH transmission on different panels, so that the transmission power of the terminal can be accurately controlled on each panel according to the used beam.

Optionally, in a possible implementation manner of this embodiment, the configuration of the power control parameter may include, but is not limited to, at least one of the following:

a set of candidate values for a power control parameter; and

a correspondence of SRIs to candidate values of power control parameters in the set of candidate values of power control parameters.

In a specific implementation process, if the configuration of the power control parameter includes the candidate value set of the power control parameter, the terminal device may specifically determine the candidate value set associated with the panel indication information or the SRS resource set from a plurality of candidate value sets of the power control parameter that are configured for the terminal device in advance by the network device.

For example, the power control parameter is a target power P_OAnd the path loss factor alpha, one candidate value set may comprise a plurality of sets of target powers P_OAnd the value combination of the path loss factor α, for example, a candidate value set with a size of N can be expressed as: { (P)_O,1,α ₁),(P _O,2,α ₂),…,(P _O,3,α _N)}。

Alternatively, or again for example, the power control parameter is a path loss measurement reference signalOne set of candidate values may then comprise the indices q of the multiple path loss measurement reference signals_dFor example, a set of candidate values of size N may be expressed as: { q ] q_d,1,q _d,2,…,q _d,N}. Wherein q is_d,iAn index of a Reference Signal for path loss measurement, such as a Channel State Information-Reference Signal (CSI-RS) resource Identification (ID).

Or, for another example, if the power control parameter is a closed loop power control process, a candidate value set may include indexes of one or more closed loop power control processes, for example, a candidate value set with a size of 2 may be represented as: {0,1}, where 0 and 1 denote l ═ 0 and l ═ 1, respectively, for independent closed loop power control processes; another set of candidate values of size 2 may be expressed as: {2,3}.

In another specific implementation process, if the configuration of the power control parameter includes a correspondence between SRIs and candidate values of the power control parameter in the candidate value set of the power control parameter, the terminal device may specifically determine, from among multiple sets of correspondences between SRIs and candidate values of the power control parameter, which are previously configured for the terminal device by the network device, a correspondence between SRIs and candidate values of the power control parameter, which are associated with the panel indication information or SRS resource set.

For example, the power control parameter is a target power P_OAnd the path loss factor alpha, the corresponding relation can be SRI and the target power P_OAnd the corresponding relation of the path loss factor alpha, namely the SRI and the candidate value set of the power control parameter { (P)_Oj,α _j) The index j of the candidate value in (1).

Or, for another example, if the power control parameter is a path loss measurement reference signal, the corresponding relationship may be a corresponding relationship between SRI and the path loss measurement reference signal, that is, the SRI and the power control parameter candidate value set { q }_d,iCandidate value q in (1) }_d,The corresponding relationship of (1).

Or, for another example, if the power control parameter is a closed-loop power control process, the corresponding relationship may be a corresponding relationship between the SRI and the closed-loop power control process, that is, a corresponding relationship between the SRI and a candidate value of the index l of the closed-loop power control process.

In a specific implementation, the network device may configure a corresponding candidate value of a set of power control parameters for each SRI value, thereby indicating a corresponding relationship between the SRI and candidate values of multiple power control parameters. The network device may configure a plurality of such correspondences, each of which is associated with a different panel indication information or SRS resource set, as shown in table 1 and table 2.

Table 1: corresponding relation of association of panel indication information value 0 or SRS resource set 0

Value of SRI	Value of j	Value of qd	Value of l
00	2	0	0
01	3	1	1
10	4	2	0
11	5	3	1

Value of SRI	Value of j	Value of qd	Value of l
00	6	4	2
01	7	5	2
10	8	6	3
11	9	7	3

In another specific implementation process, in combination with the foregoing two specific implementation processes, if the configuration of the power control parameter includes a candidate value set of the power control parameter and a correspondence between SRIs and candidate values of the power control parameter in the candidate value set of the power control parameter, then the terminal device may specifically determine, from among a plurality of candidate value sets of the power control parameter that are previously configured for the terminal device by the network device, a candidate value set associated with the panel indication information or SRS resource set, and determine, from among a plurality of sets of correspondence between SRIs and candidate values of the power control parameter that are previously configured for the terminal device by the network device, a correspondence between SRIs and candidate values of the power control parameter that are associated with the panel indication information or SRS resource set. Then, the terminal device further determines the value of the power control parameter corresponding to the SRI according to the configuration of the two determined power control parameters.

Optionally, in a possible implementation manner of this embodiment, in 220, if the configuration of the power control parameter includes the candidate value set of the power control parameter, the terminal device may specifically determine a value of the power control parameter from the candidate value set of the power control parameter according to a higher layer signaling, a system broadcast message, or an SRI included in DCI that schedules the PUSCH transmission, and a correspondence between the SRI and a candidate value in the candidate value set of the power control parameter. Then, the terminal device may determine the transmission power of the PUSCH transmission according to the value of the power control parameter.

The correspondence may be pre-configured at the network side, or may be a correspondence determined by the terminal device according to the panel indication information or the SRS resource set and associated with the panel indication information or the SRS resource set, which is not particularly limited in this embodiment.

Optionally, in a possible implementation manner of this embodiment, in 220, if the configuration of the power control parameter includes a corresponding relationship between an SRI and a candidate value of the power control parameter in the candidate value set of the power control parameter, the terminal device may specifically determine a value of the power control parameter according to an SRI included in a higher layer signaling, a system broadcast message, or DCI which schedules the PUSCH transmission, and a corresponding relationship between the SRI and a candidate value of the power control parameter in the candidate value set of the power control parameter. Then, the terminal device may determine the transmission power of the PUSCH transmission according to the value of the power control parameter.

The candidate value of the power control parameter may be a candidate value in a candidate value set of the power control parameter configured in advance by the network device, or may be a candidate value in a candidate value set of the power control parameter determined by the terminal device according to the panel indication information or the SRS resource set, which is not particularly limited in this embodiment.

In this embodiment, the terminal device determines the configuration of a power control parameter according to the panel indication information or the SRS resource set corresponding to the PUSCH transmission, where the configuration of the power control parameter is associated with the panel indication information or is associated with the SRS resource set, so that the terminal device can determine the transmission power of the PUSCH transmission according to the configuration of the power control parameter, thereby implementing independent power control on each panel used by the terminal device, and enabling the terminal device to perform PUSCH transmission with optimal transmission power.
