Method for obtaining noise power and terminal

A terminal, comprising:

• a transceiver, a memory, a processor, and a computer program that is stored in the memory and executable on the processor, wherein when executing the computer program, the processor is configured to implement following steps:
• obtaining a first power offset value of an actual automatic gain control (AGC) received power relative to a first predetermined received power within a predetermined transmission time interval (TTI);
• obtaining, according to a preset correspondence between a modulation mode and an AGC backoff value, a target AGC backoff value corresponding to a current modulation mode;
• and
• obtaining a noise power according to the first power offset value, the target AGC backoff value, and a current AGC received power.

A non-transitory computer-readable storage medium, wherein a computer program is stored thereon, and the computer program is executed by a processor to implement steps:

• obtaining a first power offset value of an actual automatic gain control (AGC) received power relative to a first predetermined received power within a predetermined transmission time interval (TTI);
• obtaining, according to a preset correspondence between a modulation mode and an AGC backoff value, a target AGC backoff value corresponding to a current modulation mode;
• and
• obtaining the noise power according to the first power offset value, the target AGC backoff value, and a current AGC received power.
