摘要： Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.

摘要： A base station, a terminal, a transmission method and a reception method that allow the data processing on a reception side to have a margin irrespective of the time position of a resource region where control information is mapped. In a base station (100), a subframe type determining unit (101) determines, according to a configuration pattern applied to the local base station apparatus and being one of a plurality of configuration patterns different between downlink and uplink subframe configurations in time division multiplex, whether a subframe to be determined is a first type of subframe where control information is mapped only to a PDCCH region or a second type of subframe where the control information is mapped to both the PDCCH region and an R-PDCCH region. An allocation region candidate determining unit (102) determines, based on a result of the determination by the subframe type determining unit (101), a mapping region, where the control information is mapped, in the PDCCH or R-PDCCH region in the subframe to be determined.

摘要： Disclosed is a wireless communication base station device that can suppress increases in terminal power consumption while being able to perform CCE allocation flexibly. In the device, a search space setting unit (103) sets search space for each wireless communication terminal device that communicates using multiple downlink unit bands. When the aggregation level of a CCE that is allocated control information addressed to the wireless communication terminal devices is less than a threshold value, an allocating unit (106) allocates the control information to a CCE inside the search space established in a single one of the multiple downlink unit bands. When the aggregation level is greater than the threshold value, the control information is allocated distributed to the CCEs inside the search spaces established for each of the multiple downlink unit bands.

摘要： Provided is a radio communication station device which can prevent limiting of resource allocation in a UE group. The radio communication device includes: a CCE allocation unit (104); modulation units (103-1 to 103-K); an arrangement unit (108); and a radio transmission unit (111). The CCE allocation unit (104) allocates allocation information allocated to a PDCCH which is inputted from the modulation unit (103-1 to 103-K) as follows. Among a plurality of search spaces shared by a greater number of UE groups as the CCE aggregation size of the PDCCH increases, a particular search space corresponding to the CCE aggregation size of the PDCCH and a mobile group (UE group) of the PDCCH is selected as a space to which the allocation information is to be allocated. The arrangement unit (108) arranges the allocation information in a downlink resource corresponding to the CCE of the particular search space allocated among the downlink resources secured for the PDCCH. The radio transmission unit (111) transmits an OFDM symbol having the allocation information from an antenna (112) to a mobile station.
