PROBLEM TO BE SOLVED: To provide a base station, terminal, communication method, and integrated circuit that facilitate efficient communication between the base station and the terminal in a communication system in which the base station and the terminal communicate with each other.SOLUTION: A terminal that communicates with at least one base station comprises: means for receiving a downlink control information (DCI) format that includes a field (SRS request) indicating whether or not to request transmission of a sounding reference signal (SRS); means for setting a reference sequence for the SRS on the basis of a first parameter if the DCI format is detected in a first control channel region (PDCCH); and means for setting a reference sequence for the SRS on the basis of a second parameter if the DCI format is detected in a second control channel region (E-PDCCH). |
