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.

摘要： A terminal and a communication method thereof whereby, even in a case of employing the asymmetric carrier aggregation system and further employing the MIMO transmission method for upstream channels, the error characteristic of control information can be prevented from being degraded. In the terminal (200), a transport signal forming unit (212) forms transport signals by arranging, based on a arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer that is different from a layer in which the channel quality information is arranged. In this way, the puncturing of CQI using ACK/NACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded.

摘要： A radio communication apparatus receives control information on one or more control channel elements (CCEs) with consecutive CCE number(s). The radio communication apparatus first-spreads a response signal with a sequence defined by a cyclic shift value that is determined among a plurality of cyclic shift values from an index of physical uplink control channel (PUCCH), which is associated with a first CCE number of the one or more CCEs, and second-spreads the first-spread response signal with an orthogonal sequence that is determined among a plurality of orthogonal sequences from the index. One of cyclic shift values used for an orthogonal sequence is determined from an index of the PUCCH, which is associated with an odd CCE number, and another one of the cyclic shift values used for the same orthogonal sequence is determined from an index of the PUCCH, which is associated with an even CCE number.
