Multicarrier communication system, multicarrier communication apparatus and CQI reporting method

摘要: Provided is a multicarrier communication apparatus by which information quantity of CQI reporting can be reduced. In the apparatus, each recorded in table section (122) being classified into plurality groups following certain rule. A selecting (123) estimates fluctuation range and variance reception qualities entire resource block to reported, based on an SINR value outputted from quality level calculating (121). Then, estimated values, selects suitable group first step, among CQIs included selected second outputs ID generating (124). Based such information, (124) generates frame transmitted base station.
