摘要

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A control method of a user equipment (UE) in a wireless communication system is provided. The method includes receiving packet data convergence protocol (PDCP) configuration information including information indicative of whether a PDCP layer supports out-of-sequence delivery; identifying whether the PDCP layer supports out-of-sequence delivery based on the PDCP configuration information; and processing a PDCP protocol data unit (PDU) based on a result of identifying whether the PDCP layer supports out-of-sequence delivery.

說(shuō)明書

In the (2-1)-th embodiment of the present disclosure, in order to support an operation for a PDCP entity to support in-sequence delivery and to not support a PDCP status report request, the PDCP entity may operate according to the following procedure in Table 1 as follows.

TABLE 1 LTE PDCP layer window operation 1 Receive PDCP PDU. 2 Discard a late arrived packet (if the sequence number (or COUNT value) of the received packet is smaller than a sequence number (or COUNT value) corresponding to a Last_submitted variable). 3 If a packet is received within a window, determine the COUNT value of the received packet and update an HFN value, if necessary. 4 If the received packet is a redundant packet, check and discard the packet. 5
