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： 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.

摘要： Provided are a base station, a terminal, a band allocation method, and a downlink data communication method in which a mapping method for synchronization signals and report signals is implemented with high resource usage efficiency when a first system in which an independent single communication is allocated to a unit band co-exists with a second system in which a plurality of unit bands can be allocated to a single communication. In a base station (200), an OFDM signal generation unit (225) maps primary synchronization channel (P-SCH), secondary synchronization channel (S-SCH), primary broadcast channel (P-BCH), and dynamic broadcast channel (D-BCH), which can be decoded by both an LTE terminal and an LTE+ terminal, to some of a plurality of unit bands available to the station itself. The OFDM signal generation unit (225) also maps D-BCH+, which can be decoded only by an LTE+ terminal, to all of the plurality of unit bands to produce a multiplexed transmission signal. When the terminal which has transmitted terminal capability information is an LTE+ terminal, a control unit (265) transmits a band movement indication which indicates changes in the reception band to that terminal.

摘要： Disclosed is a terminal device in which increase in the overhead of an uplink control channel can be suppressed even when SCTD is applied to the transmission of response signals and SRs. Either a response signal or SR is allocated to mutually different encoding resources, and a terminal (200) transmits from each of a plurality of antennas. A control section (208) transmits a response signal or SR using an SR resource or ACK/NACK resource, which are mutually different encoding resources, and a shared resource. The control section (208) uses the encoding resource, which is either the SR resource to which a response signal is allocated when a response signal and SR are generated concurrently, and to which an SR is allocated when only an SR is generated, or the ACK/NACK resource to which a response signal is allocated when only a response signal is generated. The control section (208) also uses the shared resource to which a response signal is allocated when a response signal and SR are generated concurrently and when only a response signal is generated, and to which an SR is allocated when only an SR is generated.
