Abstract: Disclosed is a communications method between a base station including a repeater and a terminal. When a terminal initiates to connect with a base station, repeaters transmit a first message including identifiers of them such that a communications path is established between the terminal and the base station through the repeaters. When data are transmitted from the base station to the terminal together with an identifier of the terminal, the data may be transmitted through a communications path preset in each repeater placed on the communications path.

Abstract: The present invention relates to an operating method of a mobile communications system operating multiple beams. A base station operating method includes: allocating a beam identifier for each of the multiple beams; transmitting the beam identifier corresponding to each of the multiple beams using each of the multiple beams; and notifying, by the terminal, the base station of the beam identifier of the selected beam. According to the operating method of the mobile communications system, a base station can rapidly detect which a terminal enters a specific beam area and rapidly process the movement of the terminal between beam areas with a minimum overhead without performing a complex procedure such as re-conducting a random access or a handover process even when the terminal moves between the beam areas.

Abstract: A terminal continues to compare the signal intensity of a serving base station and the signal intensity of a target base station and execute the handover to the target base station at the optimal point of the handover instead of executing the handover right upon receiving a handover command from the serving base station. When the point of handover is determined, the terminal transmits a message notifying the execution of the handover to the serving base station, and then executes the handover to the target base station.

Abstract: PURPOSE: A device and method for controlling the mobility of a terminal in direct communication are provided to maintain D2D(Device to Device) communication by using an existing handover procedure. CONSTITUTION: A source base station determines D2D handover for one or more terminals according to a wireless state report received from two or more terminals executing D2D communication(S603,S605). The source base station transmits a D2D handover request to a target BS(S607). When the response for the D2D handover request is received, the source base station temporally stops the D2D communication(S609,S611). The source base station transmits an RRC(Radio Resource Control) connection reconfiguration request message to a handover target terminal(S613).
