Integrated circuit for transmitting a PUCCH repetition signal using a channel format that accommodates SRS transmission

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.
