Patent ID: 8059600

Claim:
An apparatus for receiving a signal of a Base Station (BS) providing multiple communication service modes in a communication system, the apparatus comprising: a reference signal receiver for receiving, from the BS, a reference signal for each of a first communication service mode for covering the entire service area of a corresponding cell and at least one second communication service mode for covering a partial area of the first communication service mode; a broadcast channel receiver for receiving broadcast channel information from a broadcast channel of the first communication service mode; a performance estimator, upon entering a network, for acquiring synchronization with an anchor communication service mode of the network, and performing cell search; a silence time determiner for setting up a connection with a broadcast channel of the first communication service mode, and determining if a current time position is a silence time interval for transmitting the reference signals and the broadcast channel information; a communication service mode's expected performance estimator for estimating expected performance of each service mode using the broadcast channel and the reference signal; a best â€˜serving BSâ€™ -â€˜communication service modeâ€™ combination determiner for determining a best combination of a â€˜serving BSâ€™ and a â€˜communication service modeâ€™ using the expected performance of each communication service mode; and a broadcast channel receiver for receiving a reference signal of a second communication service mode in the silence time interval uniformly set for each frequency band of each communication service mode, wherein the broadcast channel information includes information on a combination of a BS, from which each user terminal can receive a service in a current position, and a communication service mode, and information on a combination of a BS of an adjacent cell and a communication service mode.
