Abstract
A user terminal includes: a transmitter that transmits delivery acknowledgement signals (HARQ-ACKs); a receiver that receives downlink control information including: in one or more predetermined subframes of the downlink control information, first information that indicates a total number of cells to be subjected to downlink (DL) transmission scheduling, and second information that indicates a cumulative number of cells; and a processor that performs control so that the HARQ-ACKs are transmitted in predetermined uplink (UL) subframes based on the first information and the second information. The HARQ-ACKs are transmitted in response to DL signals transmitted from a plurality of cells. The plurality of cells include cells that use Time Division Duplex (TDD). A value of the first information is the same in each of the one or more predetermined subframes, and the processor updates the first information on a per subframe basis.
