Claim 6:
7. A first terminal in a sidelink communication system, the first terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
establish a packet data convergence protocol (PDCP) entity for a radio bearer,
receive, from a second terminal, a first sidelink PDCP protocol data unit (PDU), and
set state variables of the PDCP entity,

wherein an initial value of a sequence number of an RX_NEXT that indicates a next PDCP PDU is set based on a sequence number of the first sidelink PDCP PDU, and
wherein an initial value of a sequence number of an RX_DELIV that indicates a PDCP PDU not delivered to an upper layer is set based on the sequence number of the first sidelink PDCP PDU.
