    摘要: In a base station (100), a division number calculating unit (103) calculates the division number of a PRB pair on the basis of a first number of REs capable of mapping an allocation control signal, a second number of REs capable of mapping signals other than the allocation control signal, and a reference value, which is the number of REs satisfying the reception quality request in a terminal (200) for the allocation control signal, in each PRB pair. Then, a control signal mapping control unit (104) determines a search space by determining a control channel element group constituting a plurality of mapping unit resource region candidates within a CCE group obtained by separating each PRB pair contained in a first group into the same number as the division number.

    摘要: In the present invention, even if different UL-DL configurations are set for a plurality of unit bands, notification timing of error detection results for SCell is not dispersed complicatedly, and the processing relating to the error detection results can be simplified. At the reference notification timing of a response signal with respect to downlink data of a second unit band, if a sub-frame of the second unit band is an uplink communication sub-frame and a sub-frame of a first unit band is a downlink communication sub-frame, a control unit (208) transmits the response signal with respect to the downlink data in a specific uplink communication sub-frame (for example, #2 or #7) set in the first unit band.

    摘要: It is possible to provide a radio communication system, a radio base station device, and a radio terminal device capable of reducing the power consumption in a radio terminal device without thinning pilot signals used for measuring upstream line quality. In the radio base station device (100) used in a radio communication system using different frequency bands for the upstream line and the downstream line, an upstream line pilot generation unit (115) forms a CQI measuring pilot signal and an upstream line RF unit (105) transmits the communication quality measuring pilot signal by using the upstream line use frequency band in the upstream line pilot transmission section. Thus, the upstream communication quality measuring pilot signal used by the radio base station device (100) to measure the line quality is transmitted by using the upstream line frequency band and accordingly, it is possible to reduce the power consumption in the radio terminal device.

    摘要: The transmission of a reference signal, such as a CSI-RS, is enabled while maintaining a power saving effect when performing inter-cell cooperative transmission/reception or the like in a plurality of cells. In order to realize inter-cell cooperative transmission/reception, a CSI-RS which is used for estimating the state of a spatial propagation path of a communication line is generated by a CSI-RS generation unit, and the CSI-RS is disposed in a predetermined subframe by a disposition unit and transmitted. At this time, when a frame has ten subframes #0 to 49, the CSI-RS is disposed in the subframes #4 and #9, which are subframes excluding the subframes #0 and #5 incapable of transmitting a CSI-RS and are subframes other than subframes capable of acting as MBSFN subframes when discontinuous communication (Extended Cell DTX) is performed so as to achieve power saving, and transmitted.
