1. A method performed by a receiving device in a wireless communication system, the method comprising:
identifying if a timer for detecting loss of radio link control (RLC) protocol data units (PDUs) is not running;
in case that the timer is not running, identifying if a value of a first state variable is equal to a value of a second state variable plus 1 and there is at least one missing segment of an RLC service data unit (SDU) before a last segment of all received segments of the RLC SDU, the RLC SDU being associated with a sequence number (SN) which is same as the value of the second state variable; and
in case that the value of the first state variable is equal to the value of the second state variable plus 1 and there is the at least one missing segment of the RLC SDU before the last segment of the all received segments of the RLC SDU, starting the timer and setting a value of a third state variable to the value of the first state variable,
wherein the first state variable holds a value of an SN following an SN of an RLC SDU with a highest SN among received RLC SDUs,
wherein the second state variable holds a value of an SN following a last in-sequence completely received RLC SDU, and
wherein the third state variable holds a value of an SN following an SN of the RLC SDU which triggered the timer.
