[0067] Figure 2 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application. The method 200 includes at least part of the following contents.

[0068] In 210, the terminal device obtains maximum transmission power and / or transmit power control (TPC) information corresponding to each SRS resource set in at least one SRS resource set.

[0069] Specifically, the terminal device may be configured with at least one SRS resource set. Each SRS resource set may include multiple SRS resources, each SRS resource may be an SRS resource with an independent configuration, and different SRS resources may have independent configurations. Different SRS resources may differ in terms of the SRS transmission period, the SRS triggering method, the number of symbols occupied by each SRS transmission, etc. The SRS resources in the same SRS resource set may be the same in at least one configuration.

[0070] Different SRS resource sets may be different in at least one configuration aspect, for example, the SRS transmission period, the SRS triggering method or the number of symbols occupied by each SRS transmission.

[0071] Optionally, the terminal device may be configured with at least one antenna panel, and each antenna panel may be configured with one or more SRS resource sets for sending SRS through the antenna panel.

[0072] Optionally, at least one SRS resource set in 210 may correspond to one or more antenna panels, and the SRS resource sets corresponding to different antenna panels may be the same or different.

[0073] It should be understood that the at least one SRS resource set in 210 may be a complete SRS resource set available to the terminal device, or may be a partial SRS resource set available to the terminal device.

[0074] For millimeter wave NR terminals, there can be multiple antenna panels, each of which forms a different beamforming pointing in different directions, and can send signals simultaneously.

[0075] When a terminal device has multiple antenna panels and sends signals simultaneously, power control is required.

[0076] In 220, the terminal device transmits the SRS using the SRS resources in each SRS resource set based on the maximum transmission power and / or TPC information corresponding to each SRS resource set.

[0077] In order to facilitate a clearer understanding of the present application, the following will describe in detail how to determine the corresponding maximum transmission power for each SRS resource set.

[0078] In one implementation, the terminal device obtains a first maximum transmit power, where the first maximum transmit power is applicable to each SRS resource set.

[0079] Specifically, the terminal device may jointly determine a maximum transmission power for at least one SRS resource set, and when the terminal device transmits an SRS using each SRS resource set in at least one SRS resource set, the maximum transmission power used is the same.

[0080] Optionally, the terminal device determines the first maximum transmission power based on the power level of the terminal device and / or configuration information of the network device.

[0081] Specifically, the terminal device may determine the first maximum transmission power with reference to its own power level and at least one parameter configured by the network device.

[0082] In one implementation, the terminal device obtains a second maximum transmit power; divides the second maximum transmit power by a specific value to obtain a power value, and determines it as the maximum transmit power corresponding to each SRS resource set, and the specific value is greater than or equal to the number of SRS resource sets corresponding to the at least one SRS resource set.

[0083] The specific value may be equal to the number of antenna panels of the terminal device, and the antenna panels of the terminal device may correspond to the SRS resource sets one by one. Alternatively, the specific value may be equal to the maximum number of SRS resource sets available to the terminal device. Alternatively, the specific value may be equal to the number of SRS resource sets that can be sent through the antenna panels of the terminal device.

[0084] Optionally, the terminal device determines the second maximum transmit power according to a power level of the terminal device and / or configuration information of a network device.

[0085] Specifically, the terminal device may determine the second maximum transmission power with reference to its own power level and at least one parameter configured by the network device.

[0086] In another implementation, the maximum transmission power corresponding to each SRS resource set or each SRS resource set group is determined independently according to the power level of the terminal device and / or the configuration information of the network device.

[0087] Each SRS resource set group may include at least one SRS resource set, wherein the at least one SRS set mentioned in 210 may belong to at least one SRS resource set group, and the terminal device may determine the maximum transmission power for each SRS resource set group according to the power level of the terminal device.

[0088] In order to facilitate a clearer understanding of the present application, the following will describe in detail how to determine the corresponding TPC for each SRS resource set.

[0089] In one implementation, TPC information corresponding to each SRS resource set is obtained from at least one signaling corresponding to the at least one SRS resource set.

[0090] Among them, at least one signaling may correspond one-to-one to at least one SRS resource set, and each signaling may carry TPC information corresponding to the SRS resource set corresponding to the signaling.

[0091] The network device may send at least one signaling in each sending period, wherein the signaling of TPC information corresponding to at least one SRS resource set may belong to the same sending period or to different sending periods.

[0092] Optionally, the signaling mentioned in the embodiment of the present application may be physical layer signaling, may be downlink control information (Downlink Control Information, DCI), and of course, may also be other signaling.

[0093] Optionally, the network device may implicitly or explicitly indicate the SRS resource set corresponding to each signaling.

[0094] Optionally, each signaling in the at least one signaling indicates a corresponding SRS resource set in an arrangement order of the at least one signaling.

[0095] For example, there are 4 signalings, the first signaling may correspond to SRS resource set 1, the second signaling may correspond to SRS resource set 2, the third signaling may correspond to SRS resource set 3, and the fourth signaling may correspond to SRS resource set 4.

[0096] Optionally, each signaling is associated with first indication information, which is used to indicate a corresponding SRS resource set.

[0097] Specifically, each signaling may include first indication information, which is used to indicate a corresponding SRS resource set.

[0098] In one implementation, the TPC information corresponding to each SRS resource set is respectively acquired from at least one TPC information field corresponding to the at least one SRS resource set.

[0099] The at least one information field may belong to the same signaling or to different signalings.

[0100] Optionally, the network device may implicitly or explicitly indicate the SRS resource set corresponding to each information domain.

[0101] Optionally, each TPC information field in the at least one TPC information field indicates a corresponding SRS resource set in an arrangement order of the at least one TPC information field.

[0102] For example, a network device sends a TPC command to a terminal device via a DCI. In this DCI, there are K TPC fields, and field 1 corresponds to set 1, field 2 corresponds to set 2, ..., field K corresponds to set K.

[0103] For example, there are four information fields, the first information field may correspond to SRS resource set 1, the second information field may correspond to SRS resource set 2, the third information field may correspond to SRS resource set 3, and the fourth information field may correspond to SRS resource set 4.

[0104] Optionally, each TPC information field is associated with second indication information for indicating a corresponding SRS resource set.

[0105] Specifically, each TPC information field may include second indication information, which is used to indicate a corresponding SRS resource set.

[0106] For example, the network device sends a TPC command to the UE via DCI. In this DCI, there are M (M<=K) fields, each field contains a TPC field and is associated with a set number k. M can be preset on the terminal device or determined by the network high-level configuration.

[0107] Optionally, the signaling carrying the at least one TPC information field is applicable to a terminal device group.

[0108] Optionally, the terminal device receives third indication information sent by the network device, where the third indication information is used to indicate a TPC information field corresponding to the terminal device and / or a TPC information field corresponding to an SRS resource set of the terminal device.

[0109] Specifically, the network device may indicate in the third indication information which information fields correspond to each of the multiple terminal devices, or indicate the correspondence between the SRS resource set and the TPC information field of a single terminal device.

[0110] For example, a network device sends a TPC instruction to a group of UEs via DCI, including multiple TPC information, and different TPC information may belong to different UEs, or different SRS resource sets (resource sets) of the same UE. The network device simultaneously configures the number of the TPC information in the DCI corresponding to the SRS resource set k of the UE via high-level signaling.

[0111] Therefore, in the embodiment of the present application, the terminal device obtains the corresponding maximum transmission power and / or transmit power control (TPC) information for each SRS resource set in at least one SRS resource set, and can implement power control in SRS transmission. In addition, when there are multiple antenna panels and each panel corresponds to a different SRS resource set, power control of SRS sent by multiple panels at the same time can be implemented to reduce uplink interference.

[0113] In 310, the network device determines at least one TPC information, where the at least one TPC information corresponds to at least one SRS resource set.

[0114] In 320, the network device sends the at least one TPC information to the terminal device.

[0115] Optionally, the at least one TPC information is carried in at least one signaling, and each signaling carries one TPC information.
