Patent ID: 7660599

Claim:
A base station combining a plurality of channel information that is divided as a unit of transmission power control from all the transmission channels and transmitting to mobile stations as downlink data, comprising: a channel priority setting unit which outputs priority information indicating priority for transmission power control about the plurality of channel information for the transmission channels that include dedicated channels set to a highest priority, control channels set to a next highest priority, and pilot channels set to a lowest priority; a power calculation unit which outputs a total power information of all channels about the plurality of channel information; and a power adjustment unit which performs power adjustment to a channel information selected on the basis of the priority information when the total power information has larger value than a maximum transmission power information; and a controlled variable calculation unit which compares the total power information with the maximum transmission power information, calculates power difference of the total power information and the maximum transmission power information when the total power information has exceeded the maximum transmission power information, and outputs power controlled variable information to perform power control to the channel information with the higher priority before performing power control to the channel information with lower priorities.
