摘要：
A cell using an unallocated frequency band or a shared frequency band is efficiently controlled. A terminal device includes a reception unit configured to monitor a physical downlink control channel (PDCCH) in a secondary cell having a frame structure type 3. In the secondary cell having the frame structure type 3, upon a first possible starting position of a downlink transmission and a second possible starting position of the downlink transmission being indicated by a higher layer, the terminal device monitors both a first set of candidates for the PDCCH and a second set of candidates for the PDCCH in a predetermined subframe. The first set of candidates is assumed to start on the basis of the first possible starting position, and the second set of candidates is assumed to start on the basis of the second possible starting position.
