Base station, terminal, and communication method

Abstract

A base station is disclosed that enables an efficient use of resources even when a TTI length is shortened. In this base station, a PDCCH section (103) generates one piece of downlink control information (DCI) containing control information for a plurality of first transmission time intervals (TTIs) each having a TTI length shorter than a second TTI, and a transmission section (107) transmits the DCI. Control information on retransmission processing for a data signal is configured for each of the plurality of first TTIs while control information other than the control information on the retransmission processing is configured in common among the plurality of first TTIs in the DCI.

Dependencies are inferred from the claim text.
