A Survey on Integrated Access and Backhaul Networks

Abstract: 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) has been proposed by the Third Generation Partnership Project (3GPP) to reduce the expenses related to the deployment of fiber optics for 5G and beyond networks. In this paper, first, a brief introduction of IAB based on the 3GPP release is presented. Then, the existing researc… Show more

“…In this regard, 3GPP envisions an integrated access and backhaul architecture for small cell BSs in which the same infrastructure and spectral resources are used by the macro BSs on the access links and the small BSs on the backhaul links [25]. This new architecture introduces new design challenges such as the proper partitioning of resources between the access and the backhaul links [26], [27].…”
