Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust an amplifier of the UE to a highest gain state after a downlink period and before an uplink period. Additionally, the UE may adjust the amplifier of the UE to a lower gain state after the uplink period and before a subsequent downlink period. Numerous other aspects are described.

Embodiments of the present invention provide a method and an apparatus for controlling transmit power of user equipment. The method includes: when total uplink transmit power of user equipment UE exceeds maximum allowed transmit power, calculating a first gain factor according to the maximum allowed transmit power; performing quantization processing on the first gain factor according to a gain factor of a first physical channel, to obtain a second gain factor, where the first physical channel includes a DPCCH2; reducing a gain factor of a second physical channel to the second gain factor, to reduce transmit power of the second physical channel, so that the total uplink transmit power of the UE does not exceed the maximum allowed transmit power, where the second physical channel includes an HS-DPCCH. This reduces a calculation error and improves control accuracy of transmit power.

A radio device includes an amplifier; a storage that stores therein distortion compensation coefficients each of which compensates distortion that is generated in the amplifier; an updater that reads, from the storage in a first time section, the distortion compensation coefficients associated with a portion of an input signal input during the first time section and stores the read distortion compensation coefficients in a memory, and that updates, in a second time section, the distortion compensation coefficients stored in the memory and writes the updated distortion compensation coefficients in the storage; and a controller that controls the updater such that, when the same input signal is repeatedly input, the distortion compensation coefficients associated with a portion that is different from the portion of the input signal input the last time are stored in the memory in the first time section.
