Abstract: A reception processor receives the cell detection reference signals, each of the cell detection reference signals being transmitted from corresponding one of a plurality of cells. An RRM report generator generates measurement information indicating a measurement result of reception quality measured using the cell detection reference signal. A transmission processor transmits the measurement information. The cell detection reference signals are mapped to any one of a plurality of candidate resources, which is a part of a plurality of resources set for other reference signals in a subframe to which the cell detection reference signals are mapped.

Abstract: If repetition transmission is applied to a response signal for a downlink data signal and an uplink signal, the uplink signal is repeatedly transmitted using a certain number of consecutive subframes starting with a first subframe, at which the repetition transmission of the uplink signal starts, and the response signal is repeatedly transmitted using at least the certain number of consecutive subframes starting with a second subframe, at which the repetition transmission of the response signal starts. The first subframe is set to be the same as the second subframe.

Abstract: Received Signal Strength Indicator (RSSI) is measured accurately even in a case where a discovery signal is transmitted. A receiver receives a plurality of subframes, at least one of which includes a discovery signal, and a measurer measures Reference Signal Reception Power (RSRP) using a first resource in which the discovery signal is mapped, measures RSSI using a second resource different from the first resource for which the discovery signal is mapped, and calculates Reference Signal Reception Quality (RSRQ) using RSRP and RSSI.

Abstract: A communication apparatus has a receiver and a decoder. The receiver receives a control signal including first downlink control information and second downlink control information, and receives decoding area information that indicates whether the extended Physical Downlink Control Channel (PDCCH) should be decoded for each of a plurality of terminal apparatuses. The decoder decodes each of a plurality of first mapping candidates in the PDCCH area or decodes each of the plurality of first mapping candidates in the PDCCH area and each of the plurality of second mapping candidates in the extended PDCCH. A number of the second mapping candidates included in the user-specific search space equals to or is more than a number of the first mapping candidates included in the common search space.

Abstract: In a base station, a control unit and a data size regulation unit control the data size of downstream assignment control data and upstream assignment control data in the PDCCH signal based on the communication format used between the base station and a terminal, the number of base station antennas (M) (nonnegative number), the number of terminal antennas (N) (nonnegative number), the bandwidth of the downstream band, and the bandwidth of the upstream band. Specifically, the control unit determines it is unnecessary to adjust the aforementioned data size when the selected communication format is first established between multiple antennas and when where there are multiple for one of M and N and only one for the other. The quality of downstream assignment control data is prevented from degrading, while preventing the number of blind determinations from increasing on the receiving side of the downstream control channel signal.

Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.
