面向超5G网络的灵活IAB架构

A Flexible IAB Architecture for Beyond 5G Network

Shashi Ranjan, Pranav Jha, Abhay Karandikar, Prasanna Chaporkar

摘要:

IAB是一种创新的无线回程解决方案,可为成功采用5G提供具有成本效益的小型基站部署。此外,IAB可以利用相同的频谱用于接入和回程目的。3GPP在版本16中对IAB进行了标准化,并将在即将发布的版本中纳入一些增强。然而,3GPP IAB架构受到一些限制,例如它不支持移动中继或双连接。本文提出了一种新颖的IAB架构,可以解决这些限制,并且对5G系统的传统操作透明。该架构还支持多RAT共存,其中接入和回程可以属于不同的RAT。这些因素(以及许多其他因素)使运营商能够利用该架构,以即插即用的方式在任何地方部署IAB。我们还显示了该架构的优点,通过评估其容量和移动性的鲁棒性相比,3GPP架构。仿真结果证实了我们的设计方法。由于其健壮的设计,该架构可以在B5G系统中竞争标准化。

英文摘要:

IAB is an innovative wireless backhaul solution to provide cost-efficient deployment of small cells for successful 5G adoption. Besides, IAB can utilize the same spectrum for access and backhaul purposes. The 3GPP standardized IAB in Release 16 and would incorporate a few enhancements in the upcoming releases. The 3GPP IAB architecture, however, suffers from some limitations, such as it does not support mobile relays or dual-connectivity. This article presents a novel IAB architecture that addresses these limitations and is transparent to legacy operations of the 5G system. The architecture also supports multi-RAT coexistence where access and backhaul may belong to different RATs. These factors (and many others) enable operators to capitalize on the architecture for deploying IAB anywhere in a plug-and-play manner. We also show the merits of the architecture by evaluating its capacity and mobility robustness compared to the 3GPP architecture. Simulation results corroborate our design approach. Owing its robust design, the architecture can contend for standardization in B5G system.
