APPARATUS AND METHOD FOR RADIO COMMUNICATIONS

摘要

A transmission power determining section (105) determines the transmission power of the communication with a mobile station based on the transmission power of the communication with a second mobile station so that it causes no interference with the communication with the second station. An SIR measurin g section (108) measures the SIR for a known reference signal in a received signal, and a transmission rate determining section (109) determines a transmission rate satisfying a desired communication quality according to th e determined transmission power and the measured SIR.
