Claim:
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, the pilot detection timeout duration being a period of time when the base station detects whether pilot data is received from the mobile communications terminal; 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.
