Abstract:
1. A power control method, adopted by a mobile device, comprising: receiving transmit power control information from a wireless communication network; determining an output power range of an amplifier according to the transmit power control information; when the output power range is less than a power range threshold, determining a low-gain switch range as an amplifier gain switch range of the amplifier, wherein the low-gain switch range comprises a first upper bound and a first lower bound; when the output power range exceeds the power range threshold, determining a high-gain switch range as the amplifier gain switch range of the amplifier, wherein the high-gain switch range comprises a second upper bound and a second lower bound, the second upper bound is less than the first upper bound, and the second lower bound is less than the first lower bound; when a transmit power of an uplink signal is within the amplifier gain switch range, amplifying the uplink signal with a first gain mode; and when the transmit power of the uplink signal is outside of the amplifier gain switch range, amplifying the uplink signal with a second gain mode.
