The receiving circuitry, in operation, controls reception of a downlink control information on one or more consecutive control channel elements (CCEs) in a search space, and controls reception of downlink data on a downlink resource that is indicated by the downlink control information, the search space being comprised of a plurality of CCEs that includes the one or more consecutive CCEs, and the plurality of CCEs starting on a CCE that is determined from both a number of the one or more consecutive CCEs, and a total number of CCEs configured in a subframe. The transmitting circuitry, in operation, controls transmission of uplink control information on an uplink resource, which is associated with a CCE index of a first CCE of the one or more consecutive CCEs.

Abstract: This invention is directed to a terminal apparatus capable of preventing the degradation of reception quality of control information even in a case of employing SU-MIMO transmission system. A terminal, which uses a plurality of different layers to transmit two code words in which control information is placed, comprises: a resource amount determining unit that determines, based on a lower one of the encoding rates of the two code words or based on the average value of the reciprocals of the encoding rates of the two code words, resource amounts of control information in the respective ones of the plurality of layers; and a transport signal forming unit that places, in the two code words, the control information modulated by use of the resource amounts, thereby forming a transport signal.

Abstract: Provided are a base station, whereby the erroneous detection of control information can be reduced, thereby preventing the degradation of the system throughput. A base station maps a downstream allocation control information unit, which is addressed to a terminal, to a first resource region, which can be used for any of a downstream control channel region and a downstream data channel region, or to a second resource region, which can be used only for the downstream control channel, so as to transmit the downstream allocation control information unit. In the base station, a control unit establishes a scale of the PDCCH region, and a transmission region establishing unit establishes, on the basis of a scale value established by the control unit, a mapping region to which the DCI is mapped within the R-PDCCH region and the PDCCH region.

Abstract: Disclosed is a base station in which the frequency usage efficiency can be improved when the communication bandwidths are asymmetric in the uplink line and the downlink line. A base station can communicate by using a plurality of downlink unit bands and a smaller number of uplink unit bands. A control unit allocates uplink resource allocation information and downlink resource allocation information to a PDCCH which is arranged in each of the plurality of downlink unit bands, and allocates a response signal to the uplink line data to a PHICH which is arranged in the same number of downlink unit bands from the plurality of downlink unit bands as there are uplink unit bands. A transmit RF unit transmits the resource allocation information or the response signal.

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.
