1、1/84AbstractMassive access technology refers to the technologies developed to address the challengeof accommodating extensive connectivity.6G sets higher demands for connection density,specifically targeting scenarios with massive connections.The envisioned connection densityfor 6G is tens of millio

2、ns of terminals per square kilometer.6G can bring about a fully digitalsociety by integrating Internet of Everything(IoE),allowing individuals to engage in natural,inspiring,and pervasive interactions with their surroundings.Each individual is anticipated toactivate tens to hundreds of terminals con

3、nected to the 6G network,with the interaction cyclefor machine-type terminals expected to decrease from 1 day or 2 hours in 5G to mere seconds.In the context of 6G,there are increased demands for low latency,particularly for the sporadictransmission of small packets by machine-type terminals.This ne

4、cessitates a further reductionin the delay from initial access to establishing a Radio Resource Control(RRC)connection,aiming to achieve simplified access procedures.6G advances the Massive Machine Type Communications(mMTC)scenario byintroducing the Massive Communication scenario,which involves a po

5、tentially enormousnumber of access terminals,reaching up to tens of millions per square kilometer.Additionally,in the context of 6G,the Immersive Communication and Hyper Reliable and Low-LatencyCommunication(HRLLC)scenarios stemming from Enhanced Mobile Broadband(eMBB)and Ultra-Reliable Low-Latency

6、Communications(URLLC)scenarios bring forth increaseddemands for indicators such as connection density and latency.To satisfy these demands,extensive research into massive access technology is essential.This white paper aims to lay out the framework of massive access technology,investigate its applic
