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

  • all stored PDCP SDU(s) with consecutively associated COUNT value(s) starting from COUNT=RX_DELIV+1;
  • update RX_DELIV to the COUNT value of the last PDCP SDU delivered to upper layers;
  • if RCVD_COUNT=RX_DELIV+1 and if outOfOrderDelivery is configured and the PDCP SDU with RCVD_COUNT has not been delivered to upper layers:
    • deliver the resulting PDCP SDU to upper layers after performing header decompression;
    • update RX_DELIV to the COUNT value of the last in-sequence delivered PDCP SDU to upper layers;
  • if outOfOrderDelivery is configured and the PDCP SDU with RCVD_COUNT has not been delivered to upper layers:
    • deliver the resulting PDCP SDU to upper layers after performing header decompression;
  • if t-Reordering is running,
    • if RX_REORD=RX_DELIV+1; or
      • if RX_REORD<=RX_DELIV (or RX_REORD falls outside of the receiving window and RX_REORD is not equal to RX_DELIV+Window_Size+1)
        • stop and reset t-Reordering;
  • if t-Reordering is not running (includes the case when t-Reordering is stopped due to actions above)
  • 權(quán)利要求
