WIRELESS COMMUNICATION SYSTEM, WIRELESS BASE STATION, WIRELESS TERMINAL STATION, AND TRANSMISSION POWER CONTROL METHOD USING THE SAME

摘要

Transmission rate detector (211) detects a transmission rate of uplink data to be transmitted to a wireless base station, compares the detected transmission rate with a preset transmission rate threshold, and outputs the comparison result to transmission power control step generator (212). Based on transmission power control information transmitted from the wireless base station and separated in separator (202) and on the comparison result output from transmission rate detector (211), transmission power control step generator (212) changes the transmission power variation range for controlling the transmission power.
