If the plurality of subframes do not include a transmission candidate subframe of a sounding reference signal used to measure uplink reception quality, a controller sets a first transmission format to all the plurality of subframes, and if the plurality of subframes include the transmission candidate subframe, the controller sets a second transmission format to all the plurality of subframes. A transmitter transmits the repetition signals using the set transmission format. ## Claims ### Claim 1 An integrated circuit comprising: control circuitry which, in operation, controls: transmitting a physical uplink control channel (PUCCH) repetition signal including a plurality of PUCCH signals in a first sounding reference signal (SRS) transmission candidate subframe and a second SRS transmission candidate subframe; and transmitting a SRS in the first SRS transmission candidate subframe and no SRS in the second SRS transmission candidate subframe, wherein a shortened PUCCH format is used for transmitting the plurality of PUCCH signals in both of the first SRS transmission candidate subframe and the second SRS transmission candidate subframe, and the first SRS transmission candidate subframe and the second SRS transmission candidate subframe are consecutive subframes; and at least one output, which is coupled to the control circuitry and which, in operation, outputs a signal. ### Claim 2 (depends on 1) The integrated circuit according to claim 1, wherein the first SRS transmission candidate subframe and the second SRS transmission candidate subframe are signaled by a base station. ### Claim 3 (depends on 1) The integrated circuit according to claim 1, wherein both of the first SRS transmission candidate subframe and the second SRS transmission candidate subframe include two slots. ### Claim 4 (depends on 3) The integrated circuit according to claim 3, wherein the shortened PUCCH format is used for transmitting the plurality of PUCCH signals in both of the two slots of the first SRS transmission candidate subframe and the second SRS transmission candidate subframe. ### Claim 5 (depends on 1) The integrated circuit according to claim 1, wherein the control circuitry controls transmitting the PUCCH repetition signal in a Machine Type Communication (MTC) coverage enhancement mode. ### Claim 6 An integrated circuit embodying logic which, when executed by a transmission apparatus, controls the transmission apparatus to perform: transmitting a physical uplink control channel (PUCCH) repetition signal including a plurality of PUCCH signals in a first sounding reference signal (SRS) transmission candidate subframe and a second SRS transmission candidate subframe; and transmitting a SRS in the first SRS transmission candidate subframe and no SRS in the second SRS transmission candidate subframe, wherein a shortened PUCCH format is used for transmitting the plurality of PUCCH signals in both of the first SRS transmission candidate subframe and the second SRS transmission candidate subframe, and the first SRS transmission candidate subframe and the second SRS transmission candidate subframe are consecutive subframes. ### Claim 7 (depends on 6) The integrated circuit according to claim 6, wherein the first SRS transmission candidate subframe and the second SRS transmission candidate subframe are signaled by a base station. ### Claim 8 (depends on 6) The integrated circuit according to claim 6, wherein both of the first SRS transmission candidate subframe and the second SRS transmission candidate subframe include two slots. ### Claim 9 (depends on 8) The integrated circuit according to claim 8, wherein the shortened PUCCH format is used for transmitting the plurality of PUCCH signals in both of the two slots of the first SRS transmission candidate subframe and the second SRS transmission candidate subframe. ### Claim 10 (depends on 6) The integrated circuit according to claim 6, wherein the PUCCH repetition signal is transmitted in a Machine Type Communication (MTC) coverage enhancement mode.
