WIRELESS COMMUNICATION SYSTEM, BASE STATION APPARATUS, AND MOBILE STATION APPARATUS

摘要

A wireless communication system, a mobile station apparatus and a base station apparatus wherein the frequency usage efficiency is improved and a high-speed mobile communication is achieved. This wireless communication system comprises a mobile station and a base station, which use a plurality of communication channels and a pilot channel corresponding to at least one of the communication channels to have wireless communication with each other. The base station has a transmitting means that employs at least one of the communication channels as a priority channel and transmits channel information of this priority channel and the other channels by use of a communication channel other than the pilot channel. The mobile station has a determining means that determines a reception level of the pilot channel transmitted by the base station; an acquiring means that acquires the channel information transmitted via the communication channel other than the pilot channel; and a deciding means that decides, as an available communication channel, at least one of the communication channels based on both the channel information acquired by the acquiring means and the reception level determined by the determining means.
