摘　　要：5G-NR和B5G系统都需能高效地支持小微数据包(块)的传输,且在不同的无线传输技术(如宽带或超低时延)之间快速灵活地切换。系统梳理和比较和小微数据包(块)相关的多种无线传输技术,如两步RACH、预配置授权和公共资源竞争等,分析它们对3GPP各个系统和各个RAN协议的影响和复杂度优劣等,并进一步展望其未来发展和应用趋势。Both 5G-NR and B5G systems need to efficiently support the transmission of small and micro data packets(blocks),and switch between different wireless transmission technologies(such as broadband or ultra-low delay)rapidly and flexibly.This paper systematically reviews and compares various wireless transmission technologies related to small and micro data packets(blocks),such as two-step RACH,pre-configuration authorization and public resource competition,and analyzes their impacts on 3GPP systems and RAN protocols as well as their complexity advantages and disadvantages.Furthermore,the prospects of their future developments and application trends are prospected.
