| Abstract: | 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. |
