Abstract
In a radio communication system including a plurality of mobile station apparatuses and a base station apparatus a physical uplink reference signal and a physical uplink control channel signal are efficiently controlled and the mobile station apparatus appropriately transmits a signal. The mobile station apparatus includes: a radio resource control unit 403 that sets a radio resource of a reference signal for measuring channel quality and a radio resource of a physical uplink control channel; a simultaneous transmission control unit 4051 which when transmitting the physical uplink control channel signal in a time frame in which the radio resource of the reference signal has been set controls a signal transmission processing depending on whether each radio resource has been set to the same component frequency band or each radio resource has been set to a different component frequency band; and a transmission processing unit 407 that transmits the reference signal and/or the physical uplink control channel signal based on the control of the simultaneous transmission control unit.

Claim
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
transmit only the PUCCH of a first format, without transmitting the SRS, or
simultaneously transmit the SRS and the PUCCH of a second format,
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.
2. The mobile station apparatus according to claim 1, wherein
in the first format, all SC-FDMA symbols of a subframe are used, and
in the second format, SC-FDMA symbols excluding the last SC-FDMA symbol of the subframe are used.
3. The mobile station apparatus according to claim 1, wherein the PUCCH is a PUCCH used for transmission of a scheduling request or for transmission of a reception acknowledgement response.
4. A communication method for a mobile station apparatus configured to communicate with a base station apparatus, the communication method comprising:
transmitting at least a signal by using one or more component frequency bands each having a predetermined frequency bandwidth,
wherein transmitting at least the signal comprises:
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, determining based on a format of the PUCCH whether to
transmit only the PUCCH of a first format without transmitting the SRS, or
simultaneously transmit the SRS and the PUCCH of a second format,
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,
transmitting only the PUCCH of the first format without transmitting the SRS, and simultaneously transmitting the PUCCH of the second format and the SRS, in a case that the subframe is an SRS subframe of the second component frequency band to which transmission of the PUCCH is set; and
transmitting only the PUCCH of the first format without transmitting the SRS, in a case that the subframe is not the SRS subframe.
5. The communication method according to claim 4, wherein
in the first format, all SC-FDMA symbols of a subframe are used, and
in the second format, SC-FDMA symbols excluding the last SC-FDMA symbol of the subframe are used.
6. The communication method according to claim 4, wherein the PUCCH is a PUCCH used for transmission of a scheduling request or for transmission of a reception acknowledgement response.
7. An integrated circuit to be mounted on a mobile station apparatus, the integrated circuit causing the mobile station apparatus to perform at least functions of:
transmitting at least a signal by using one or more component frequency bands each having a predetermined frequency bandwidth,
wherein transmitting at least the signal comprises:
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 a same subframe, determining based on a format of the PUCCH whether to transmit only the PUCCH of a first format without transmitting the SRS, or simultaneously transmit the SRS and the PUCCH of a second format, 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,
