发明名称 Mobile communication system, relay station, and control method and program for relay station
摘要 In order to properly operate a fixed relay station and a mobile relay station even under the circumstance where the fixed relay station and the mobile relay station are connected to the same base station, each of relay stations (20—1 and 20—2) forming a mobile communication system (1) notifies a base station (10) of type information which indicates a type of whether or not each relay station is a movable relay station. The base station (10) performs, for each of the relay stations (20—1 and 20—2), at least one of configuration and control according to the type. Further, when the type indicates the movable relay station, the base station (10) notifies information on the at least one of configuration and control to a neighboring base station via an upper layer control device.

主权项 1. A mobile communication system comprising: a first base station; and a relay station that conducts a wireless relay between the first base station and a mobile station, wherein the relay station notifies the first base station of type information indicating a type of whether or not the relay station itself is a movable relay station, wherein the first base station receives the type information from the relay station and performs, for the relay station, at least one of configuration and control according to the type that is determined based on the type information, wherein when the type indicates the movable relay station, the first base station allocates, upon the configuration, a reference signal specific to a cell formed by the first base station itself as a reference signal for causing the relay station to demodulate a radio signal from the first base station itself, and wherein said at least one of configuration and control when the relay station is the movable relay station is different from said at least one of configuration and control when the relay station is not the movable relay station.
