1. A method for controlling a transmission power, comprising:
determining a target number of transmission cycles according to a service scenario of an electronic device, wherein a preset time window is divided into the target number of transmission cycles, and the preset time window is a test cycle used in a specific absorption rate (SAR) test of the electronic device;
determining at least one of an upper limit value or a lower limit value of a transmission power corresponding to each transmission cycle, wherein an average value of transmission powers in the preset time window complies a SAR requirement; and
controlling the electronic device to transmit and receive signals using a corresponding transmission power in each transmission cycle;
wherein determining the upper limit value of the transmission power corresponding to each transmission cycle comprises:
determining an upper limit adjustment value of the transmission power corresponding to each transmission cycle according to the service scenario;
determining the upper limit value of the transmission power corresponding to each transmission cycle by obtaining a sum of a limited power under the SAR requirement and the upper limit adjustment value.
