摘要： In a mobile communication system, a relay station connects to a first or second base station, and communicates with a mobile station at a timing corresponding to the destination base station. Before execution of a handover for switching a destination of the relay station from the first base station to the second base station, the relay station transmits a signal regarding the second base station. The mobile station synchronizes with the relay station after execution of the handover, on the basis of the signal regarding the second base station which is received from the relay station before the handover.

摘要： In a mobile communication system, a mobile station receives intermittently a channel transmitted by a first or second base station through a relay station. Herein, the relay station, before execution of a handover for switching a connection destination of its own station from the first base station to the second base station, transmits information on the second base station. The mobile station, based on the information on the second base station received from the relay station before the handover, controls a timing for receiving the channel from the relay station after the handover.
