Abstract

A base station according to one embodiment comprises a controller configured to perform a downlink transmission process using a subframe. The subframe comprises a main PDCCH (Physical Downlink Control Channel) region located at a head portion of the subframe, and a data region other than the main PDCCH region. The data region comprises a short TTI region to which a short TTI (Transmission Time Interval) having a shorter time length than the subframe is applied. The short TTI region comprises a sub-PDCCH region. The controller is configured to arrange information indicating the sub-PDCCH region in the main PDCCH region.
