1. A method implemented by a terminal, wherein the method comprises:
receiving, from a network device, first information indicating a first uplink-downlink configuration; and
performing uplink transmission on a plurality of uplink time resources indicated by the first uplink-downlink configuration,
wherein an actual transmit power for the uplink transmission is equal to a first difference between a first maximum transmit power of the terminal and an actual power decrease and meets a specific absorption rate (SAR) specification,
wherein the actual power decrease is based on a first power decrease and a first power increase and is less than the first power decrease,
wherein the first power increase is equal to a second difference between a second maximum transmit power in the first uplink-downlink configuration that meets the SAR specification and a third maximum transmit power in a second uplink-downlink configuration that meets the SAR specification,
wherein a first uplink time proportion in the first uplink-downlink configuration is less than a second uplink time proportion in the second uplink-downlink configuration, and
wherein the first power decreases a transmit power from the first maximum transmit power to a fourth maximum transmit power that meets the SAR specification when the terminal is at a first distance from a human body in the second uplink-downlink configuration.
