MOBILE COMMUNICATION SYSTEM, RELAY STATION, AND BASE STATION

摘要

A mobile communication system includes a base station and a relay station. The base station transmits carrier information to the relay station during connection of a first radio link using a first carrier. The carrier information indicates at least one candidate carrier available for performing multi-carrier communication on the first radio link. The relay station transmits, to the base station, request information about a configuration of the first radio link for the at least one candidate carrier indicated by the carrier information. The base station further determines, in response to receiving the request information from the relay station, a second carrier used with the first carrier for the multi-carrier communication.
