High-Speed Packetization for 5G Advanced

Abstract

The first (Release 15) 5G communication standard called NR was completed by the 3rd Generation Partnership Project (3GPP). One of the key changes deviated from 4G communication standard called LTE is to design a new data structure enabling pre-processing and application of hardware accelerator to reduce data processing time. However, User Plane Integrity Protection (UPIP) was adopted to provide secure communication as a mandatory feature in the late stage of Release 16, which incurs significant performance degradation on data processing. In this paper, maximum Service Data Unit (mSDU) processing approach is proposed to achieve high data rates with robust security, which still enables pre-processing and application of hardware accelerator. Theoretical analysis proves that mSDU processing outperforms the legacy NR data processing with respect to overhead, processing time, and data throughput. In numerical results, it is showed that mSDU processing provides performance gain over 60%, compared with the legacy NR data processing.
