  • Patent number: 8488532
    Abstract: 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 and successively receives the SCSCH (Shared Control Signaling Channel) of each predetermined available Chunk from the head of a radio frame. If the SCSCH has a mobile station identifier of the mobile station assigned, the mobile station receives an SDCH (Shared Data Channel) of the corresponding RB (Resource Block) and acquires a CID (Chunk ID). Here, user data may be simultaneously contained in the SDCH. The mobile station registers the acquired CID in the Chunk Table. Moreover, the base station side also has the Chunk Table corresponding to each mobile station and manages whether a CID has been allocated for each mobile station.
