Abstract:
1. A mobile station apparatus comprising: a transmission processor configured to transmit at least a signal by using one or more component frequency bands each having a predetermined frequency bandwidth, wherein the transmission processor is configured to in a case that transmission of an SRS (Sounding Reference Signal) for a first component frequency band and transmission of a PUCCH (Physical Uplink Control Channel) for a second component frequency band are set in the same subframe, determine based on a format of the PUCCH whether to the first format is a format which is based on an orthogonal sequence with a sequence length of 4 for a second slot of the subframe and the second format is a format which is based on an orthogonal sequence with a sequence length of 3 for the second slot of the subframe, in a case that the subframe is an SRS subframe of the second component frequency band to which transmission of the PUCCH is set, the transmission processor is configured to transmit only the PUCCH of the first format without transmitting the SRS, and simultaneously transmit the PUCCH of the second format and the SRS, and in a case that the subframe is not the SRS subframe, the transmission processor is configured to transmit only the PUCCH of the first format without transmitting the SRS.
