Mobile Communications Terminal, and Method for Controlling Radio Frequency Power Amplifier Thereof

摘要

The present invention discloses a mobile communications terminal. The mobile communications terminal includes a signal processing module and a radio frequency power amplifier, where the signal processing module outputs, to a radio frequency signal input end of the radio frequency power amplifier, a radio frequency signal corresponding to one group of data packets, and synchronously outputs an enable signal to an enable signal input end of the radio frequency power amplifier; and the signal processing module periodically stops outputting the enable signal to the enable signal input end within first predetermined duration, and outputs, to the radio frequency signal input end, a radio frequency signal corresponding to at least one piece of pilot data and synchronously outputs the enable signal to the enable signal input end within second predetermined duration.

1. A mobile communications terminal comprising:
a radio frequency power amplifier; and a signal source connected to the radio frequency power amplifier, and configured to output, to a radio frequency signal input end of the radio frequency power amplifier, a radio frequency signal corresponding to a first group of data packets, the signal source further configured to synchronously output an enable signal to an enable signal input end of the radio frequency power amplifier; wherein the signal source is configured to, within a duration between a first time after the radio frequency signal corresponding to the first group of data packets is output to the radio frequency signal input end and a second time when a radio frequency signal corresponding to a second group of data packets is output to the radio frequency signal input end, periodically stop outputting the enable signal to the enable signal input end for a first predetermined duration, and output, to the radio frequency signal input end, a radio frequency signal corresponding to at least one piece of pilot data and synchronously output the enable signal to the enable signal input end for a second predetermined duration; wherein the first predetermined duration is less than a pilot detection timeout duration of a base station with which an uplink traffic channel is being established; and wherein the first group of data packets and the second group of data packets each comprise data packets to be transmitted over the uplink traffic channel with the base station.
