SMALL BASE STATION, USER TERMINAL, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention is designed so that a small cell detection/measurement signal is introduced without making an impact on existing systems. Where a small cell (S) covered by a small base station (10) is placed within a macro cell (M) covered by a macro base station (20) and a user terminal (30) is present within the small cell, the small base station generates a detection/measurement signal for a new detection process, which is different from an existing small cell detection process using synchronization signals, and maps the detection/measurement signal to avoid the synchronization signals and transmits the detection/measurement signal to the user terminal, and the user terminal receives the detection/measurement signal from the small base station and detects the small cell.
