Abstract: This application provides example methods for controlling an output power of an antenna for user equipment. One example method includes, during a sounding reference signal (SRS) transmission period, transmitting, by a first antenna of at least one antenna of the user equipment, a first SRS signal to a base station at a first SRS output power, where the first SRS output power is equal to a maximum output power (Pcmax) of the first antenna. During the SRS period, a non-SRS signal is transmitted to the base station at a non-SRS output power, where the non-SRS output power is less than a difference between the maximum output power of the first antenna and a maximum output power reduction of the first antenna, and the maximum output power reduction of the first antenna is set to meet an electromagnetic power density exposure requirement of the first antenna.

Abstract: Embodiments of this application provide an uplink resource pre-application method and a related device. An electronic device may predict encoding duration of a to-be-sent data packet in an application (APP), determine an encoding completion moment of the to-be-sent data packet, and send an uplink scheduling request to a network device before the encoding completion moment of the to-be-sent data packet, to apply for an uplink resource for the to-be-sent data packet in advance. In this way, a latency of sending uplink data by the electronic device may be reduced, and power consumption of the electronic device may be reduced.
