FIELD: radio engineering, communication.SUBSTANCE: radio communication method for radio communication using a plurality of frequency bands in a first radio communication device and a second radio communication device. The method includes steps of: the first radio communication device transmitting to the second radio communication device a first channel state information request corresponding to each of a plurality of frequency bands; and the second radio communication device transmitting to the first radio communication device information relating to channel state with respect to the frequency band indicated by the first channel state information request when the second radio communication device receives the first channel state information request.EFFECT: reporting information relating to channel state in an arbitrary transmission frequency band from a plurality of frequency bands, and high throughput.48 cl, 77 dwg |
