Abstract: A radio unit (RU) in a directional communication network establishes a connection with a first antenna among two antennas of a first TE in a first moving object that first enters a serving duration of the RU according to a network access request from the first antenna, and when receiving the network access request from a second antenna among two antennas of a second TE in a second moving object that next enters the serving duration, the RU processes the network access request from the second antenna based on network access priority of the second antenna and network access priority of the first antenna to which the connection is established.

Abstract: A method and apparatus for scheduling a beam in a mobile communication system are provided. A terminal receives signals through a plurality of switching beam directions, and receives a plurality of beams that are transmitted while performing beam switching in a transmission time interval (TTI) unit by a base station. The terminal selects a signal having largest intensity among received signals, and transmits an uplink scheduling request signal in a beam direction corresponding to the selected signal.
