摘要： A communications system of the present invention is an OFDMA system (100) including a base station (10) and mobile stations (20), the base station (10) communicating wirelessly with the mobile stations (20) over a plurality of channels. Each mobile station (20) includes: a reception quality measuring section (19) for measuring reception quality; and a reception quality information determining section (12) for generating reception quality information only for each subgroup that belongs to the group(s) allocated to that mobile station (20) to report, (i) by 2-step grouping scheme information by which the channels are divided into subgroups, the subgroups are divided into groups, and the groups are allocated to the mobile stations (20) and (ii) according to the reception quality measured by the reception quality measuring section (19). The base station (10) schedules wireless communications over the channels according to the reported reception quality information. Accordingly, the amount of the reception quality information sent from the terminals to the base station is reduced to improve throughput.

摘要： Reception quality measurement results of respective channels which have been outputted from a reception quality measuring section 308 are inputted to a selected channel determining section 341 and a channel quality information generating section 342. Moreover, the number of selected channels M which has been previously defined or the number of selected channels M which has been outputted from a control information obtaining section 314 is inputted to the selected channel determining section 341 and a channel identification information generating section 343. The selected channel determining section 341 selects M channels in order of goodness of the reception quality measurement result, as the selected channels, based on the reception quality measurement results of the respective channels, and outputs a selection result. The channel quality information generating section 342 generates and outputs channel quality information representing the reception quality measurement results related to the selected M channels, based on the selection result outputted from the selected channel determining section 341. The channel identification information generating section 343 selects one of a first representation format for representation with M identification numbers (channel numbers) indicating the respective selected channels, and a second representation format for representation with a bit sequence representing whether or not each of all the channels is included in the selected channels, in a binary manner, based on the number of selected channels M, and uses the selected representation format to generate and output channel identification information based on the selection result outputted from the selected channel determining section 341. A multiplexing section 344 combines the channel quality information outputted from the channel quality information generating section 342 and the channel identification information outputted from the channel identification information generating section 343 to generate and output notification information.
