Abstract
Embodiments of this application provide a power headroom reporting method for user equipment, a medium, and user equipment. The reporting method includes: The user equipment has at least a first uplink transmit antenna and a second uplink transmit antenna, the first uplink transmit antenna has a first P_MPR value, and the second uplink transmit antenna has a second P_MPR value; and when the user equipment performs uplink data transmission in a single-stream manner, the user equipment sends a first PHR value to a network side, where the first PHR value is obtained based on at least a third power management maximum power reduction P_MPR value, and the third power management maximum power reduction P_MPR value is between the first P_MPR value and the second P_MPR value. According to the power headroom reporting method in this application, an actual maximum transmit power that is obtained through calculation and that is of the user equipment is more accurate, and further, the user equipment can report the power headroom more accurately.
