Abstract
A wireless communication apparatus is provided including: a radio receiver configured to acquire, from a base station, a first information indicating a fixed number identifying quantity of sub-carrier bands to be selected for channel quality reporting; a reception quality measurer configured to measure channel quality of each of a plurality of sub-carrier bands within a communication band; a subcarrier selector configured to select sub-carrier bands from the plurality of sub-carrier bands based on the measured channel quality, wherein quantity of the selected sub-carrier bands matches the quantity of sub-carrier bands identified by the fixed number; a modulator configured to modulate a second information indicating channel quality of the selected sub-carrier bands and a third information indicating positions of the selected sub-carrier bands according to a modulation scheme; and a radio transmitter configured to report to the base station the second and third modulated information.
