Patent ID: 7194240

Claim:
A radio communication apparatus that is applied to a radio communication system and communicates with other radio communication apparatus in the radio communication system using one available channel or a plurality of channels, the radio communication apparatus comprising: a reception processing unit that, when input reception signals of the channels of the radio communication system is received, measures reception states of input reception signals of each of the channels, generates local channel reception information of each of the channels based on a result of the measurement, and applies a reception processing to the input reception signals to generate decoded signals; a media-access-control unit that, when data is transmitted using two or more channels, generates transmission frames for each of the channels using transmission data; a transmission processing unit that generates radio signals including each of the transmission frames; and a channel-information processing unit that generates local feedback information based on the local channel reception information, and inserts the local feedback information generated into one of the radio signals or a plurality of the radio signals, wherein the radio communication apparatus transmits the radio signals including the local feedback information.
