Abstract: A terminal according to an aspect of the present disclosure includes: a receiving section configured to receive a configuration of a physical uplink control channel (PUCCH) for at least one of a scheduling request (SR) and channel state information (CSI); and a control section configured to control respective transmission of a plurality of repetitions of the PUCCH over a plurality of subslots based on the configuration. According to one aspect of the present disclosure, suitable PUCCH repetition transmission can be implemented.

Abstract: This terminal comprises a control unit that determines a cell to transmit control information on the basis of a timing pattern indicating the order of cells to transmit the control information, and a transmitting unit that transmits the control information in the determined cell. If the timing pattern includes Scell to be de-activated, the timing pattern is changed before Scell is de-activated.
