Abstract:
1. A wireless communication apparatus comprising: a subcarrier number determining section that determines the number of subcarriers to allocate to every communicating party; a first transmission section that transmits information about the number of subcarriers determined in the subcarrier number determining section, to said every communicating party; and an allocation control section that selects subcarriers to allocate transmission data for said every communicating party based on channel quality information of the number of subcarriers for said every communicating party extracted from a received signal, wherein, when a sum of the amount of data of the channel quality information about the subcarriers selected by the communicating party and the amount of subcarrier identification information indicating the subcarriers selected by the communicating party is larger than the amount of data of channel quality information about all subcarriers in a communication band, the subcarrier number determining section determines the number of said all subcarriers in the communication band as the number of subcarriers to allocate to the communicating party.
