Abstract

The present invention is designed so that communication overhead pertaining to control signals is reduced in a communication system in which the bandwidth of a physical downlink shared channel is narrower than the system bandwidth. The radio base station of the present invention has a resource allocation section that allocates a physical downlink shared channel to a predetermined narrow band in a downlink system bandwidth, for a user terminal, and a downlink control information generating section that generates downlink control information to report to the user terminal, and the downlink control information generating section determines the size of a field pertaining to resource allocation information, included in downlink control information related to the physical downlink shared channel, based on the narrow band where the physical downlink shared channel is allocated.
