Abstract: 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.

Abstract: 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.

Abstract: Provided is a terminal apparatus in which, a transmission control unit (204) controls the transmission power of a sounding reference signal (SRS) by use of an offset value relative to the transmission power of a data signal, and a transmission unit (206) transmits the SRS by use of the transmission power as controlled. If a subframe to be used for transmitting the SRS is a predetermined subframe, the transmission control unit (204) uses a first offset value to control the transmission power of the SRS. Otherwise, the transmission control unit (204) uses a second offset value to control the transmission power of the SRS, The second offset value is an offset value that has been established so as to be transmitted to the serving cell of the terminal (200), and the first offset value is greater than the second offset value.
