摘要： The present invention is designed so that beamforming can be executed properly even when user terminals are in idle mode. A user terminal communicates with a radio base station that uses beamforming, and has a receiving section that receives a synchronization signal and/or a broadcast channel and a paging channel, which are transmitted using a single beam pattern or a plurality of beam patterns; and a control section that exerts control so that at least part of the paging channel is received based on a resource where the synchronization signal and/or the broadcast channel are allocated.
