1. A method performed by a first terminal in a sidelink communication system, the method comprising:
establishing a packet data convergence protocol (PDCP) entity for a radio bearer;
receiving, from a second terminal, a first sidelink PDCP protocol data unit (PDU); and
setting 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.
