Mobile communication system, relay station, base station, control method thereof, and computer readable medium

摘要

A mobile communication system includes a base station and a relay station. The relay station acquires a donor cell list indicating at least one candidate cell that can be used for a backhaul link. The relay station or the base station determine a donor cell used for the backhaul link from the donor cell list based on both first and second cell management information. The first cell management information relates to the at least one candidate cell and originates from the at least one base station. The second cell management information originates from the relay station.

1. A mobile communication system comprising:
at least one base station; and a relay station that relays transmission and reception data to and from a mobile station by using a backhaul link connected to one of the at least one base station and an access link connected to the mobile station, wherein the relay station is configured to acquire a donor cell list indicating at least one candidate cell, one of a first base station, included in the at least one base station, and the relay station is configured to determine a donor cell, to be connected to the relay station by the backhaul link, from the donor cell list based on both first cell management information and second cell management information, the first cell management information relates to the at least one candidate cell and originates from the at least one base station, and the second cell management information originates from the relay station, the first cell management information includes cell configuration information indicating a time-division implementing status of a radio resource of the at least one candidate cell, the second cell management information includes type information of the relay station indicating whether a radio resource time-division of the backhaul link is necessary, and when a type of the relay station indicates that a radio resource time-division is necessary between an access link and a backhaul link, the first base station or the relay station determines a cell in which a radio resource time-division is already implemented among the at least one candidate cell as the donor cell.
