The first base station is operable to broadcast configuration information to the user equipment for connecting to at least one of the one or more second base stations. The user equipment is operable to transmit an uplink signal to at least one of the one or more second base stations in accordance with the configuration information received from the first base station, and at least one of the one or more second base stations is operable to transmit information on the user equipment that transmitted the uplink signal to the first base station after receiving the uplink signal.
