    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： In a radio communication system in which a base station and a terminal communicate with each other, the base station is capable of efficiently notifying the terminal of control information. The base station sets monitoring of a second control channel in the terminal through RRC signaling that is higher-layer control information, the second control channel being transmitted using a second transmit port different from a first transmit port used for transmission of a first control channel. The base station transmits control information for the terminal by mapping the control information to the second control channel. The first transmit port is a transmit port used for transmission of a cell-specific reference signal that is a reference signal common within a cell, and the second transmit port is a transmit port used for transmission of a terminal-specific reference signal that is a reference signal specific to the terminal.
