Abstract
Disclosed is a PDCP packet transmission method, which improves the transmission performance of UE and eNB by suggesting a method for preventing data loss at the application end, caused by an invalid deciphering result which is generated when 2048 or more PDCP SDUs with sequence numbers assigned thereto are discarded, and a wireless transmission/reception unit (WTRU) including a PDCP entity. The method for transmitting PDCP packet, includes the steps of: receiving a PDCP SDU from an upper layer; determining whether or not sequence numbers are assigned to less than a predetermined number of PDCP SDUs subsequent to the last PDCP PDU completely and successfully transmitted from a lower layer; and if sequence numbers are assigned to less than the predetermined number of PDCP SDUs, assigning a sequence number to the PDCP SDU received from the upper layer.
