  • Radio communication apparatus
    Publication number: 20070155393
    Abstract: A reception processing unit measures reception states of input reception signals of each of a plurality of channels, generates local channel reception information, and applies a reception processing to the input reception signals to generate decoded signals. A media-access-control unit generates transmission frames for each of the channels using transmission data. A transmission processing unit generates radio signals including each of the transmission frames. A channel-information processing unit generates local feedback information, and inserts the local feedback information generated into at least one of the radio signals that are transmitted by the radio communication apparatus.
    Type: Application
