Claim of US Patent No. 10,368,296

1. A user terminal comprising:a receiving section that receives a first cell detection indication that specifies information applicable for a discovery signal measurement and includes timing information and assist information transmitted from a second cell;
a detection section that detects a synchronization signal included in a discovery signal transmitted from a first cell, in accordance with the timing information; and
a measurement section that performs the discovery signal measurement using a CSI-RS that is included in the discovery signal and is configured separately from a CSI-RS configured for channel state measurement, in accordance with the assist information and the synchronization signal detected,
wherein the timing information includes values of an offset, a period and a duration of the discovery signal,
the assist information includes values of a physical cell ID of the first cell or a transmission point, a scrambling ID used for the CSI-RS for discovery, a resource configuration and a subframe offset, and
the subframe offset is an offset between a subframe of a synchronization signal of a cell identified by the physical cell ID and a subframe of the CSI-RS of the first cell.
