Method and apparatus for device-to-device communication in wireless communication system

摘要

The present invention relates to a method for device-to-device communication (D2D) in a wireless communication system. Particularly, the method is characterized in that when a device, which has been conducting device-to-device communication, additionally conducts device-to-device communication with a new device, a channel sequence of the device conducting the communication is determined, one of two devices conducting the device-to-device communication is determined as a reference device for channel synchronization and channel synchronization is thereby performed.

主权项

1. A method of performing D2D (device-to-device) communication in a wireless communication system, the method comprising:
transmitting a sync request message by a first user equipment (UE) operating with a first channel sequence to a second UE operating with a second channel sequence; receiving a sync response message containing information on the second channel sequence of the second UE from the second UE in response to the sync request message; and determining a third channel sequence determined by the first UE based on information on the first channel sequence and the received information on the second channel sequence, wherein the sync response message comprises channel synchronization reference UE information becoming a reference of channel synchronization between the first UE and the second UE.
