Method for reporting power headroom for SRS, terminal device, and computer storage medium

A terminal device, comprising:

• a processor and a memory configured to store computer-executable instructions that, when executed by the processor, cause the processor to perform operations of:
• calculating at least one expected sounding reference signal (SRS) transmit power on at least one SRS resource comprised in a target SRS resource set, wherein the target SRS resource set is an SRS resource set on a target bandwidth part (BWP) and the at least one SRS resource comprised in the target SRS resource set comprises multiple SRS resources;
• when the terminal device does not transmit an SRS on the target BWP at a moment of calculating power headroom (PH), the target SRS resource set is an SRS resource set with a minimum set index among multiple SRS resource sets on the target BWP;
• obtaining the PH of the target SRS resource set through calculation according to the at least one expected SRS transmit power on the at least one SRS resource;
• and
• reporting the PH of the target SRS resource set obtained through calculation.

A non-transitory computer storage medium, having stored thereon computer-executable instructions, that when executed by a processor of a terminal device, cause the terminal device to perform a method for reporting power headroom (PH) for a sounding reference signal (SRS), the method comprising:

• calculating, by the terminal device, at least one expected SRS transmit power on at least one SRS resource comprised in a target SRS resource set, wherein the target SRS resource set is an SRS resource set on a target bandwidth part (BWP) and the at least one SRS resource comprised in the target SRS resource set comprises multiple SRS resources;
• when the terminal device does not transmit an SRS on the target BWP at a moment of calculating the PH, the target SRS resource set is an SRS resource set with a minimum set index among multiple SRS resource sets on the target BWP;
• obtaining, by the terminal device, the PH of the target SRS resource set through calculation according to the at least one expected SRS transmit power on the at least one SRS resource;
• and
• reporting, by the terminal device, the PH of the target SRS resource set obtained through calculation.
