## Abstract

A DCI receiving unit receives downlink control information (DCI) indicative of allocation of an uplink (UL) signal of a first TTI (long TTI) or an uplink signal of a second TTI (sTTI) having a shorter TTI length than the first TTI; a transmission power determination unit determines transmission power of the uplink signal of the first TTI and transmission power of the uplink signal of the second TTI; and a transmitting unit transmits the uplink signal of the first TTI and the uplink signal of the second TTI by using the determined transmission power on the basis of the downlink control information. The transmission power determination unit reserves desired transmission power for the uplink signal of the second TTI in the first TTI in a case where decoding of the downlink control information indicative of allocation of the uplink signal of the second TTI to be transmitted within the first TTI (e.g., a subframe) is completed before start of transmission of the uplink signal of the first TTI.
