[0065] Example one:
[0066] Suppose that in the CA scenario, the network side equipment configures uplink resources for the primary cell PCell and the secondary cell set {SCell_1, SCell_2, SCell_3} through high-level signaling. Among them, the uplink resources of each cell are configured with multiple SRS resource sets, such as Table 1 shows. Assume that the periodic configuration of the SRS resource set on PCell / SCell_1 / SCell_2 / SCell_3 is T time slot, and the time slot offset is 0 / 1 / 2 / 3 respectively.
[0067] Table 1
[0068]
[0069] When high-level signaling configures SRS carrier switching transmission, the UE will select the SRS resource set for AntennaSwitching for transmission. Such as image 3 As shown, on the PCell, the UE will transmit SRS resource set 3 according to the period T and the slot offset is 0; on SCell_1, the UE will transmit SRS resource set 3 according to the period T and the slot offset is 1. ; On SCell_2, the UE will transmit SRS resource set 3 according...

[0070] Example two
[0071] Suppose that the UE receives the SRS configured by the high-level signaling from the network side device and adopts independent power control, adopts the first type of power increase or decrease command, and the SRS resource set includes 0, 1, 2, and 3. Assuming that the SRS power increase or decrease command in the DCI format is {1, -1, +1}, which respectively represent {SRS request field value, SRS set 0 power increase or decrease command, SRS set 1 power increase or decrease command}. The SRS request field value is 2 corresponding to the first SRS list, including SRS resource sets 0 and 1.
[0072] The definition of the SRS request field in the DCI format is shown in Table 2.

[0076] Example three
[0077] Suppose that the UE receives the SRS configured by the high-level signaling from the network side device and adopts independent power control, and adopts the second type of power increase or decrease command, and the SRS resource set includes 0, 1, and 2. Assuming that the SRS power increase or decrease commands in the DCI format are {'01', -1}, {'10', 0}, {'11', +1}, which respectively represent {SRS request field value, SRS aggregate N power Raise or lower commands}.
[0078] The definition of the SRS request field in the DCI format is shown in Table 3.
[0079] table 3
[0080] SRS request field value SRS non-carrier switching instructions '00' No type 1SRS resource collection trigger or all type 1SRS resource collection trigger '01' Type 1 SRS resource set 1SRS trigger '10' 2nd SRS resource collection type 1SRS trigger '11' 3 SRS resource collection type 1 SRS trigger
