Patent ID: 8831610

Claim:
A radio communication system comprising: a radio base station; a radio relay station configured to connect to the radio base station; and a radio terminal; wherein, when the radio relay station connects to the radio base station, the radio base station assigns one of a finite number of relay-station identifications to the radio relay station and transmits the assigned relay-station identification to the radio relay station, and the radio relay station subsequently transmits a radio signal comprising the assigned relay-station identification; wherein the radio base station notifies the radio terminal of handover candidate information including a predetermined number of station identifications, wherein the station identifications comprise the assigned relay-station identification when the radio relay station is connected to the radio base station, and wherein the predetermined number is set based on the number of radio relay stations connectable to the radio base station at the same time; and wherein, subsequent to receiving the handover candidate information from the radio base station, the radio terminal performs a cell search according to the station identifications included in the handover candidate information.
