Abstract
A base station according to an embodiment is a base station configured to perform transmission to a user terminal by use of an unlicensed band. The base station comprises: a controller configured to start the transmission from a boundary of a subframe, but also to start the data transmission from a second-half slot out of a first-half slot and the second-half slot which configure a subframe. The controller is configured to transmit downlink control information in the second-half slot to start the transmission from the second-half slot. The controller is configured to change a modulation scheme to be applied to the transmission, depending on a start timing of the transmission, while fixing a transport block size applied to the subframe. The downlink control information is a PDCCH or an EPDCCH.
