Claim:
1. A wireless terminal comprising: a control unit including an encoder; a radio frequency power amplifier coupled to the control unit; and an antenna coupled to an output of the radio frequency power amplifier, wherein the control unit is configured to initiate a procedure for establishing a physical channel link between the wireless terminal and a server, wherein the control unit is further configured to detect whether there is data to be transmitted in the encoder and to determine that there is no uplink data to be transmitted through the physical channel link when there is no data to be transmitted in the encoder, wherein the control unit is further configured to send a first gain control instruction to the radio frequency power amplifier when there is no uplink data to be transmitted through the physical channel link within a first preset time, wherein the first gain control instruction is used for reducing a gain of the radio frequency power amplifier while the radio frequency power amplifier is powered on, wherein the radio frequency power amplifier is configured to adjust a gain level of the radio frequency power amplifier according to the gain control instruction, and wherein the antenna is configured to transmit a radio frequency signal amplified by the radio frequency power amplifier based on the adjusted gain level.
