TRANSMISSION POWER CONTROL METHOD AND BASE STATION DEVICE

摘要

A division section (205) divides the output signal of a demodulating section (204) into data and control signals such as a CQI signal and an ACK/NACK signal. A transmission power control section (261) controls the gain of an amplifying section (262) by adding an offset to the transmission power of a transmission power control section (258) when the destination apparatus is not in an HO state. Also, the transmission power control section (261) controls the gain of the amplifying section (262) based on the CQI signal when the destination apparatus is in an HO state. Furthermore, the transmission power control section (261) adds a compensation value input from a compensation value setting section (260) as set to the transmission power, for example, at retransmission. By this configuration, it is possible to improve the system throughputofthewirelesscommunicationsystem providing an HSDPA service by optimally controlling the transmission power of an A-DPCH. <IMAGE>
