Base station device, mobile station device, mobile station identifier allocation method, program, and recording medium
First Claim
1. A base station device used in a mobile communication system, comprising:
- a processor configured to assign for a mobile station device one or more groups of physical positions of radio resources each made up of a frequency component corresponding to one or more sub-carriers and a time component corresponding to one or more OFDM symbols to which mobile station identifier fields are mapped within shared control information, where the shared control information is used to assign a resource used at the time of reception from or transmission to the base station device by the mobile station device,the base station device allocating to the mobile station device a first mobile station identifier for identifying the mobile station device among one or more mobile station devices having the groups of physical positions of mobile station identifier fields assigned.

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.

11. A mobile station device used in a mobile communication system,
the mobile station device receiving a first mobile station identifier for identifying the mobile station device among one or more mobile station devices having at least one or more assigned groups of physical positions of radio resources each made up of a frequency component corresponding to one or more sub-carriers and a time component corresponding to one or more OFDM symbols to which mobile station identifier fields are mapped— - likely to be used by the mobile station device assigned by a base station device among groups of physical positions to which mobile station identifier fields are mapped within shared control information, where the shared control information is used to assign a resource used at the time of reception from or transmission to the base station device by the mobile station device.

19. A mobile station identifier allocation method used in a mobile communication system, wherein
a base station device assigns for a mobile station device one or more groups of physical-positions of radio resources each made up of a frequency component corresponding to one or more sub-carriers and a time component corresponding to one or more OFDM symbols to which mobile station identifier fields are mapped within shared control information likely to be used by the mobile station device, and wherein the base station device allocates to the mobile station device a first mobile station identifier for identifying the mobile station device among one or more mobile station devices having the groups of physical positions of mobile station identifier fields assigned.
