Abstract

It is possible to effectively control information on allocation of a radio resource for each mobile station, improve the frequency use efficiency of the entire communication system, and effectively execute base station/mobile station control. A mobile station holds a Chunk Table (TB) in advance (S1) and successively receives SCSCH of each predetermined available Chunk from the head of the radio frame (S2). If the SCSCH has a mobile station identifier of the mobile station assigned, the mobile station receives SDCH of the corresponding RB and acquires CID (Chunk ID) (S3). Here, user data may be simultaneously contained in the SDCH. The mobile station registers the acquired CID in the Chunk Table (S4). Moreover, the base station side also has the Chunk Table corresponding to each mobile station and manages whether CID has been allocated for each mobile station.
