摘要： A terminal (200) includes: a reception unit (220) configured to receive, from a base station, synchronization blocks and an indication triggering contention free random access; a control unit (240) configured to identify a synchronization block, a random access preamble and a random access channel resource for use in the contention free random access based on the indication triggering contention free random access; and a transmission unit (210) configured to transmit the identified random access preamble to the base station using the identified synchronization block and the identified random access channel resource. The indication triggering contention free random access includes information indicating random access channel occasions. The control unit (240) is configured to identify, based on the information indicating random access channel occasions, the random access channel resource. A number of the synchronization blocks in each of the random access channel occasions includes 1, 2, 4, 8, and 16. An index of the random access preamble is common for the synchronization blocks.

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.
