RADIO COMMUNICATION EQUIPMENT AND TRANSMISSION RATE DETERMINATION METHOD IN RADIO COMMUNICATION EQUIPMENT

摘要

PPROBLEM TO BE SOLVED: To determine an optimum transmission rate and to improve throughput. PSOLUTION: An SIR report value extraction part 131 of a base station device 100 in this invention extracts line quality information from data received from a communicating partner, and a doppler frequency detection part 121 detects a doppler frequency from the data. An SIR averaging necessity determination part 125 determines whether or not to average the line quality information by comparing the doppler frequency with the reciprocal of the transmission delay time of the line quality information and generates an averaging necessity determination result. An SIR averaging part 135 averages the line quality information on the basis of the averaging necessity determination result. An MCS allocation part 127 determines the transmission rate on the basis of the average line quality information and the doppler frequency. PCOPYRIGHT: (C)2007,JPO&INPIT
