Patent ID: 11031993

Abstract:
Provided are a method and an apparatus for performing device-to-device (D2D) relay communication according to various embodiments. Disclosed are the method and the apparatus for performing device-to-device (D2D) relay communication, the method comprising the steps of: receiving a first signal that is beamformed and including counter information and a message, the counter information including at last one counter comparison value established for each direction and at least one counter value; and comparing the at least one counter comparison value established for mutually corresponding directions and the at least one counter value to determine at least one transmission direction, and beamforming a second signal for relaying the message for each of the at least one transmission direction and transmitting same, wherein the second signal includes the counter information in which a counter value corresponding to a transmission direction from among the at least one counter value is modified by a predetermined value, when transmitted in one direction among the at least one transmission direction.
