摘要： A communication system that can improve the efficiency with which a Control Channel (CCH) is used in a resource. The communication system includes a base station (10), a terminal B that is inside an arrival coverage of a physical control format indicator channel (PCFICH) signal containing a control format indicator (CFI), and a terminal A that is outside the arrival coverage. The base station (10) updates the CFI during a time period of 1 ms and updates the physical hybrid ARQ indicator channel (PHICH) duration during a time period of 40 ms. The base station (10) performs scheduling of the data to be sent to the terminal B for each subframe, whereas the base station (10) performs scheduling of the data to be sent to the terminal A only in a subframe in which the PHICH duration value matches the CFI value. The terminal A acquires data to be sent to the terminal A on the basis of the CCH region size determined in accordance with the PHICH duration value transmitted from the base station (10).

摘要： In a mobile station (10), a report control unit (17) reports first precoding information and third precoding information in reporting first channel state information, and does not report the third precoding information and reports second precoding information in reporting second channel state information. The first precoding information is information corresponding to the first channel state information and used in horizontal direction beam formation in a base station and the second precoding information corresponds to the second channel state information. Further, the third precoding information is information corresponding to both of the first channel state information and the second channel state information and used in vertical direction beam formation in the base station.

摘要： A wireless communication system (1) controls a transmission timing in each cell so that a control channel of a first cell and a data channel of a second cell temporally overlap each other. The wireless communication system (1) includes a base station (100) of the first cell. The base station (100) of the first cell includes a first control unit (100a) and a first communicating unit (100b). The first control unit (100a) notifies a base station of the second cell of information used to specify a resource of the control channel of the first cell, where the resource corresponds to a predetermined resource unit. The first communicating unit (100b) transmits a control signal to a mobile station of the first cell by using a first resource of the control channel of the first cell, where the first resource corresponds to at least a part of the predetermined resource unit and that serves as a decoding object of the mobile station of the first cell.
