Abstract
Embodiments herein disclose a method for identifying a unicast Device to Device (D2D) communication. Further, the method includes generating, by a source User Equipment (UE), a D2D Media Access Control (MAC) Protocol Data Unit (PDU) comprising a unicast parameter. Further, the method includes transmitting, by the source UE, the D2D MAC PDU to the destination UE. Further, the method includes receiving, by the destination UE, the D2D MAC PDU. Further, the method includes detecting, by the destination UE, one of unicast parameters and groupcast parameters of the D2D MAC PDU. Furthermore, the method includes identifying, by the UE, the D2D MAC PDU is for one of the unicast D2D communication when the unicast parameters are detected, and the groupcast D2D communication when the groupcast parameters are detected.

16. A method for device to device (D2D) communication of a first terminal, the method comprising:
-
generating a media access control (MAC) header comprising first information for identifying whether a MAC service data unit (SDU) is for a groupcast or a unicast; transmitting a MAC protocol data unit (PDU) including the MAC header and the MAC SDU to a second terminal or a group including the second terminal. - View Dependent Claims (17, 18, 19, 20)

21. A method for device to device (D2D) communication of a first terminal, the method comprising:
-
receiving, from a second terminal, a media access control (MAC) protocol data unit (PDU) including a MAC service data unit (SDU) and a MAC header comprising first information for identifying whether the MAC SDU is for groupcast or unicast; and identifying whether the MAC SDU is for groupcast or unicast based on the first information. - View Dependent Claims (22, 23, 24, 25)
