WIRELESS COMMUNICATION SYSTEM, COMMUNICATION TERMINAL DEVICE, AND BASE STATION INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To reduce the interference in a base station instrument even when a communication terminal device in soft handover exists in wireless communication system which performs scheduling of uplink channels.

SOLUTION: A separation part 110 separates the result of demodulation of a received signal into reception data and a TPC command showing an increase or decrease in transmission power. A base station selection part 120 selects a main base station instrument whose line quality is the most superior in response to the TPC command and outputs base station selection information. A transmission power control part 130 determines transmission power in response to the TPC command. A redundant transmission power computation part 140 calculates the redundant transmission power by subtracting the determined transmission power from the maximum transmission power which can be transmitted, and outputs the redundant transmission power information. A selection multiplex part 150 multiplexes transmission data, the base station selection information and the redundant transmission power information. A transmission part 160 transmits multiplexed data.
