7. A user equipment (UE) in a device-to-device (D2D) communication system, the UE comprising:
a transceiver configured to transmit and receive data; and
at least one processor configured to:
identify a priority assigned for a packet to be transmitted, the packet being mapped to a logical channel associated with the priority and a destination to which the packet is to be transmitted,
select the destination having the logical channel of a highest priority among logical channels having data for transmission,
select, from among a plurality of transmission resource pools, a transmission resource pool in which one of associated priorities of the transmission resource pool is equal to a priority of a logical channel with the highest priority among logical channels identified in a medium access control protocol data unit (MAC PDU), wherein the transmission resource pool is associated with two or more priorities,
allocate resources for transmission from the transmission resource pool to the logical channel having the highest priority among logical channels belonging to the destination,
generate the MAC PDU, and
control the transceiver to transmit the MAC PDU based on the transmission resource pool,
wherein, if resources for transmission remain, the logical channels belonging to the destination are served in descending order of priority until either data for the logical channels belonging to the destination is exhausted or a grant for transmission is exhausted.
