摘要

The reception quality measurement result of each channel outputted from a reception quality measurement section (308) is inputted into a selection channel determining section (341) and a channel quality information generating section (342). A predetermined number of selection channels M or the number of selection channels M outputted from a control information acquiring section (314) is inputted into the selection channel determining section (341) and a channel identification information generating section (343). The selection channel determining section (341) selects M channels as selection channels in order of goodness of the reception quality measurement results and outputs the selection results. The channel quality information generating section (342) generates and outputs channel quality information representing the reception quality measurement results about the M selection channels according to the selection results outputted from the selection channel determining section (341). The channel identification information generating section (343) selects one of a first expression form in which the selection channels are expressed with respective M identification numbers (channel numbers) and a second expression form in which whether or not each of all the channels is one of the selection channels is expressed with a binary bit sequence according to the number of selection channels M and generates channel identification information according to the selection results outputted from the selection channel determining section (341) by using the selected expression form. A multiplexing section (344) combines the channel quality information outputted from the channel quality information generating section (342) with that outputted from the channel identification information generating section (343) and thereby generates and outputs report information.
