发明名称 CLOSED-LOOP TRANSMISSION POWER CONTROL METHOD AND RADIO BASE STATION DEVICE
摘要 <p>To set an optimal transmission power control interval such that a base station apparatus properly receives signals from a mobile station, while exploiting fast scheduling and fast AMC, in this closed-loop transmission power control method, reception SINR and average interference level are measured in a signal received in uplink, a time period for averaging reception quality is determined corresponding to an overlapped size of a dynamic range of a base station apparatus (10) that is a region of overlapping a first reception-allowable range depend on reception capability of the base station apparatus, with a second reception-allowable range, varying corresponding to the interference level, depend on the number of a modulation and coding scheme set, each set achieving required throughput, the reception SINR is averaged using the determined time period, and a TPC command indicative of uplink transmission power to be controlled in a terminal apparatus (30) is generated using a difference value between the averaged reception SINR and target reception SINR, and is transmitted in downlink.</p>
