COMMUNICATION METHOD FOR EFFICIENT POWER SAVING OF UE-RELAY OPERATION USING D2D DISCOVERY IN CELLULAR SYSTEM

摘要

Disclosed are a communication method and a terminal for power saving in a UE-relay operation by which power consumption in a device relay is reduced using D2D discovery. The relay communication method of a terminal is provided. The method includes performing relay communication to serve at least one other terminal; performing a device-to-device (D2D) discovery operation to detect a nearby relay terminal during the relay communication; and if the nearby relay terminal that satisfies a predetermined condition is detected as a result of the D2D discovery operation, terminating service to at least the one other terminal.
