Patent ID: 8248990

Claim:
A transmission device, comprising: a frequency scheduling part configured to: allocate either a resource block or a distributed-type resource block to each user, the resource block being consecutive frequency subcarrier blocks obtained by dividing a system bandwidth, and the distributed-type resource block being frequency subcarrier blocks discretely-distributed in the system bandwidth and being obtained by dividing the resource block into plural parts, assign identification numbers and locations of the distributed-type resource blocks obtained by dividing the resource block by a predetermined dividing number corresponding to an allocation unit number for distributed-type resource blocks allocated by the resource block, and determine the distributed-type resource blocks to be allocated to a user based on the assigned locations of the distributed-type resource blocks; a mapping part configured to allocate transmission data to either the resource block or the distributed-type resource blocks in accordance with the allocation; and a control information generating part configured to generate control information with respect to a mobile station to which either the resource block or the distributed-type resource blocks are allocated based on the identification numbers.
