BASE STATION DEVICE, UPSTREAM SINR MEASURING METHOD, UPSTREAM SCHEDULING METHOD AND RECEIVIG QUALITY MEASURING METHOD

摘要

A mobile station transmits to a base station, a control signal (ACK signal/NACK signal etc.) having limited given patterns for performing communication control processing at the base station, and the base station performs uplink SINR measurement using this control signal. Moreover, an approach of measuring SINR using such a control signal and an approach of measuring SINR using a dedicated signal for SINR measurement similarly to a conventional technique are switched between according to the availability of the control signal. Furthermore, based on a result of uplink SINR measurement, scheduling of the uplink is performed. At the scheduling, frequency scheduling may be performed by measuring SINR for each frequency block, using a control signal in which subcarriers are distributed.
