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

Directly transmit PDUs to a higher layer regardless of the sequence.

In the (2-4)-th embodiment of the present disclosure, the PDCP entity supports the PDCP operation mode in which out-of-sequence delivery is supported and a PDCP status report request is supported.

The PDCP entity of a receiving state may use a push window method, such as in FIG. 2F, or may use a pull window method, such as in FIG. 2G. Alternatively, data may be processed using the push window method, while an HFN determination may be made using the pull window method.

In the (2-4)-th embodiment of the present disclosure, in order to support an operation for a PDCP entity to support out-of-sequence delivery and to support a PDCP status report request, the PDCP entity may operate according to the following procedure in Table 4 shown below.

TABLE 4 LTE PDCP layer window operation
