Abstract

The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for communication by a base station is provided. The method includes transmitting a scheduling assignment including a first part of a destination identifier (ID), and transmitting a medium access control (MAC) protocol data unit (PDU) including a MAC header including a user equipment (UE) ID and a second part of the destination ID.

 identifying a medium access control (MAC) protocol data unit (PDU) including at least one MAC service data unit (SDU) and a MAC header, wherein the MAC header includes at least one MAC subheader and a subheader for D2D communication; and   transmitting the MAC PDU over a channel for D2D communication,   wherein the subheader for D2D communication comprises information on a version of a format of the MAC PDU, information on an identity of a source, and information on an identity of a destination.   
     
     
         2 . The method of  claim 1 , wherein the information on the identity of a source includes an identifier (ID) of the electronic device. 
     
     
         3 . The method of  claim 1 , wherein the information on the identity of the destination includes an ID of another electronic device or an ID of an electronic device group. 
     
     
         4 . The method of  claim 1 , wherein the subheader for D2D communication is placed ahead of the at least one MAC subheader in the MAC header. 
     
     
         5 . The method of  claim 4 , wherein if the MAC header further includes at least one padding subheader for one-byte padding or two-byte padding, the at least one padding subheader is placed after the subheader for D2D communication and before the at least one MAC subheader. 
     
     
         6 . A method for device to device (D2D) communication by an electronic device, the method comprising:
 receiving a medium access control (MAC) protocol data unit (PDU) including at least one MAC service data unit (SDU) and an MAC header over a channel for D2D communication, wherein the MAC header includes at least one MAC subheader and a subheader for D2D communication; and   processing the received MAC PDU,   wherein the subheader for D2D communication comprises information on a version of a format of the MAC PDU, information on an identity of a source, and information on an identity of a destination.   
     
     
         7 . The method of  claim 6 , wherein the information on the identity of a source includes an identifier (ID) of another electronic device which transmitted the MAC PDU. 
     
     
         8 . The method of  claim 6 , wherein the information on the identity of the destination includes an ID of the electronic device or an ID of an electronic device group where the electronic device belongs. 
     
     
         9 . The method of  claim 6 , wherein the subheader for D2D communication is placed ahead of the at least one MAC subheader in the MAC header. 
     
     
         10 . The method of  claim 9 , wherein if the MAC header further includes at least one padding subheader for one-byte padding or two-byte padding, the at least one padding subheader is placed after the subheader for D2D communication and before the at least one MAC subheader. 
     
     
         11 . An electronic device for device to device (D2D) communication, the electronic device comprising:
 a transceiver; and   at least one processor coupled to the transceiver, wherein the at least one processor is configured to:
 identify a medium access control (MAC) protocol data unit (PDU) including at least one MAC service data unit (SDU) and a MAC header, wherein the MAC header includes at least one MAC subheader and a subheader for D2D communication; and 
 transmit the MAC PDU over a channel for D2D communication, 
   wherein the subheader for D2D communication comprises information on a version of a format of the MAC PDU, information on an identity of a source, and information on an identity of a destination.   
     
     
         12 . The electronic device of  claim 11 , wherein the information on the identity of a source includes an identifier (ID) of the electronic device. 
     
     
         13 . The electronic device of  claim 11 , wherein the information on the identity of the destination includes an ID of another electronic device or an ID of an electronic device group. 
     
     
         14 . The electronic device of  claim 11 , wherein the subheader for D2D communication is placed ahead of the at least one MAC subheader in the MAC header. 
     
     
         15 . The electronic device of  claim 14 , wherein if the MAC header further includes at least one padding subheader for one-byte padding or two-byte padding, the at least one padding subheader is placed after the subheader for D2D communication and before the at least one MAC subheader. 
     
     
         16 . An electronic device for device to device (D2D) communication the electronic device comprising:
 a transceiver; and   at least one processor coupled to the transceiver, wherein the at least one processor is configured to:
 receive a medium access control (MAC) protocol data unit (PDU) including at least one MAC service data unit (SDU) and a MAC header over a channel for D2D communication, wherein the MAC header includes at least one MAC subheader and a subheader for D2D communication, and
