Abstract: A method of positioning a terminal includes: receiving a first radio signal generated through beamforming from a base station; obtaining a cell ID and a beam ID from the first radio signal; obtaining a received signal intensity of the first radio signal; and estimating a first position of the terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with the cell ID, the beam ID, and the received signal intensity obtained from the first radio signal.

Abstract: A terminal starts a first timer for detecting an RLF (Radio Link Failure) when signal strength of a serving base station is lower than a reference value. The terminal triggers a handover without a TTT (Time to Trigger) for handover when signal strength of a target base station is greater than the signal strength of the serving base station by a first offset or more while the first timer is running. The terminal transmits a measurement report message regarding the signal strength of the target base station to the serving base station when a handover is triggered.

Abstract: In a communication environment using a millimeter wave band, a method and apparatus that enable a base station to process data are provided. A protocol stack is generated based on a characteristic of traffic that is provided to a terminal, and the generated protocol stack is allocated to the terminal. Data to be provided to the terminal is processed according to the generated protocol stack, and data that is processed through a beam that is allocated based on a position vector of the terminal is transmitted.
