Abstract
A mobile station apparatus includes a transmission circuit or circuitry. The mobile station apparatus is configured to transmit a sounding reference signal (SRS) in a single carrier-Frequency Division Multiple Access (SC-FDMA) symbol corresponding to an SRS symbol. In addition, the mobile station apparatus is configured to, in a case that a region for SRS transmission on a given component carrier is extended based on a higher layer signal, transmit a first SRS in the SC-FDMA symbol, and transmit a second SRS in the extended region, where the first SRS is an SRS transmitted based on a first higher layer signal and the second SRS is an SRS transmitted based on a second higher layer signal and an SRS request in a physical downlink control channel (PDCCH).
