TRANSMISSION/RECEPTION APPARATUS AND TRANSMIT POWER CONTROL METHOD

摘要

A reception quality measurement section (108) measures the reception quality, a bit judging section (111) judges whether the TPC bit is 0 or 1, an amplitude reading section (112) reads the ratio of the amplitude of the signal other than the TPC bit to that of the TPC, a cumulating section (113) judges the change and changed amount of the transmission power on the assumption that the code of the TPC bit is a change of the transmission power and that the amplitude ratio is the changed amount of transmission power and gives a transmission amplifier (104) an instruction, and a multiplying section (114) multiplies the amplitude of the signal other than the TPC bit by a correction value corresponding to the reception quality and determines the amplitude of the TPC bit.
