Claim of US Patent No. 10,485,018

1. A method for communication by a base station, the method comprising:transmitting control information 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 second part of the destination ID,
wherein in response to identifying that the first part of the destination ID being destined for a user equipment (UE), receiving data for device to device (D2D) communication at a physical layer of the UE, the MAC PDU obtained from the data is delivered to a MAC layer of the UE from the physical layer,
wherein in response to identifying that the second part of the destination ID being destined for the UE at the MAC layer, a MAC service data unit (SDU) included in the MAC PDU is delivered to a radio link control (RLC) layer entity for reception of the data, and
wherein the RLC layer entity is identified with a packet data convergence protocol (PDCP) layer entity based on a source UE ID, a logical channel identifier (LCID), and the destination ID.
