综合接入网与回程网综述

A Survey on Integrated Access and Backhaul Networks

Yongqiang Zhang, Mustafa A. Kishk, Mohamed-Slim Alouini

摘要:

受益于高频带的使用,将大的可用带宽的一部分用于无线回程是可行的,而不会有相当大的性能牺牲。在这种背景下,3GPP提出了集成接入和回程(IAB),以降低5G及更高网络的光纤部署成本。本文首先介绍了基于3GPP的IAB协议。然后,我们综述了IAB网络的现有研究,IAB到高速缓存使能网络,光通信传输网络和非地面网络的集成。最后,我们讨论了IAB网络开发和商业化过程中可能出现的挑战和机遇。

英文摘要:

Benefiting from the usage of the high-frequency band, utilizing part of the large available bandwidth for wireless backhauling is feasible without considerable performance sacrifice. In this context, integrated access and backhaul (IAB) was proposed by 3GPP to reduce the fiber optics deployment cost of 5G and beyond networks. In this paper, we first give a brief introduction of IAB based on the 3GPP release. After that, we survey existing research on IAB networks, the integrations of IAB to cache-enabled network, optical communication transport network, and the non-terrestrial network. Finally, we discuss the challenges and opportunities that might arise while developing and commercializing IAB networks.
