Embodiment 1
[0090] Such as figure 1 As shown, it is a flowchart of a method for controlling the transmission power of a sounding reference signal of the present invention for aperiodic SRS embodiment 1. The method includes:
[0091] Step 101: The network side configures multiple sets of SRS power control parameters or multiple SRS power compensation values for the UE through radio resource control protocol (RRC) signaling;
[0092] Step 102: The UE selects SRS power control parameters according to the correspondence between multiple sets of SRS power control parameters or multiple SRS power compensation values and specific signaling content that triggers the A-SRS command in the DCI format (format);
[0093] For example, the network side configures three sets of sounding reference signal power control parameters for the UE through RRC signaling, namely {the first set of power control parameters, the second set of power control parameters, the third set of power control parameters}, and the p...
Embodiment 2
[0100] Such as figure 2 Shown is a flow chart of the second embodiment of the aperiodic SRS control method for sounding reference signal transmission power according to the present invention. The method includes:
[0101] Step 201: The network side configures multiple sets of SRS power control parameters or multiple SRS power compensation values for the UE through radio resource control protocol (RRC) signaling;
[0102] Step 202: The UE selects SRS power control parameters according to multiple sets of SRS power control parameters or the corresponding relationship between multiple SRS power compensation values and DCI formats.
[0103] For example, the network side configures 5 sets of sounding reference signal power control parameters for the UE through RRC signaling, namely {the first set of power control parameters, the second set of power control parameters,..., the fifth set of power control parameters}, and At this time, the power control parameter corresponds to the DCI ...
Embodiment 3
[0109] Such as image 3 Shown is a flow chart of the third embodiment of aperiodic SRS using the method for controlling sounding reference signal transmission power according to the present invention. The method includes:
[0110] Step 301: The network side configures multiple sets of SRS power control parameters or multiple SRS power compensation values for the UE through radio resource control protocol (RRC) signaling;
[0111] Step 302: The UE selects SRS power control parameters according to the correspondence between multiple sets of SRS power control parameters or multiple SRS power compensation values and the DCI format and the content of the A-SRS trigger command in the DCI format;
[0112] For example, the network side configures 7 sets of sounding reference signal power control parameters for the UE through RRC signaling, namely {the first set of power control parameters, the second set of power control parameters,..., the seventh set of power control parameters}, and A...
