MOBILE COMMUNICATION SYSTEM, WIRELESS BASE STATION, AND MOBILE COMMUNICATION METHOD

摘要

A mobile communication system includes a plurality of radio base stations (410) communicating with an UE (10). Each of the plurality of radio base stations (410) comprises an interface (415) that notifies another radio base station (410) of synchronization information through a backhaul network, the synchronization information designating a synchronization state between the radio base station (410) and the UE (10).
