Communication method and apparatus in which a total power of power control information is a fixed valued

摘要

When a base station and a plurality of terminal stations communicate with each other by radio, reception situations of signals transmitted from a base station are measured by respective terminal stations and measured information is transmitted to the base station. When the base station adaptively sets processing of signals transmitted to the respective terminal stations based on the transmitted information and multiplexes and transmits, from the base station to a plurality of terminal stations, power control information (RPC) for instructing electric power of signals transmitted from the respective terminal stations to the base station, transmission energy to individual terminal stations are set adaptively and transmission electric power at the respective terminal stations are set based on the power control information. Thus, information such as power control information that should individually instructed to the respective terminal stations can satisfactorily be transmitted to all terminal stations by a simple arrangement and simple processing.
