Abstract:
1. A radio communication apparatus for performing radio communication in a first frequency band and a second frequency band, the radio communication apparatus comprising: a first modem which modulates/demodulates a first frequency band signal; a second modem which modulates/demodulates a second frequency band signal; and a modem controller which determines on the basis of information supplied from the first and second modems that transmitting/receiving timing of first radio communication collides with transmitting/receiving timing of second radio communication and which directs the first modem to avoid collision of data on a time axis, wherein the first modem is configured to control communication of frame data in which the same data is allocated to a plurality of communication slots, and in receiving a directive from the modem controller that transmitting/receiving timing of the second modem collides with transmitting/receiving timing of the first modem, the first modem discards the data contained in a colliding communication slot and rewrites a control data sent to a radio receiver of the frame data for directing the radio receiver to select another communication slot of the allocated communication slots containing the same data within the frame data.
