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.

說明書

Referring to FIG. 3A, the wireless communication system includes multiple eNBs 3a-05, 3a-10, 3a-15 and 3a-20, an MME 3a-25 and an S-GW 3a-30. A UE (or terminal) 3a-35 accesses an external network through the eNB 3a-05, 3a-10, 3a-15, and 3a-20 and the S-GW 3a-30.

The eNBs 3a-05, 3a-10, 3a-15 and 3a-20 are access nodes of a cellular network, and provide radio access to UEs that access a network. For example, the eNBs 3a-05, 3a-10, 3a-15, and 3a-20 collect state information, such as a buffer state, available transmission power state and channel state of UEs, schedules the UEs, and supports connections between the UEs and a core network (CN) in order to serve the traffic of the UEs. The MME 3a-25 is a device responsible for various control functions in addition to a mobility management function for a UE, and is connected to multiple eNBs. The S-GW 3a-30 provides a data bearer. The MME 3a-25 and the S-GW 3a-30 may further perform authentication and bearer management on a UE that accesses a network, and processes packets arrived from the eNBs 3a-05, 3a-10, 3a-15 and 3a-20 or packets to be delivered to the eNB 3a-05, 3a-10, 3a-15 and 3a-20.
