NR Integrated Access and Backhaul
2021As an advanced NR feature, integrated access and backhaul (IAB) is specified in 3GPP Rel-16 to enable wireless backhauling using NR air interface and layer-2 relaying. IAB is considered as an important NR capability to resolve the backhauling issue and facilitate cell densification. In this chapter, we introduce the architecture and the key features of

Integrated Access and Backhaul in Fixed Wireless Access Systems
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017In this work we evaluate the potential of using access-integrated backhaul in a fixed wireless access (FWA) use case. FWA is considered as a potential use case for early 5G deployment. The system is deployed in the 28 GHz band to provide FWA to residential houses in a suburban scenario where the access points (APs) are deployed on utility poles.

Mesh Architecture for Efficient Integrated Access and Backhaul Networking
2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020Integrated access and backhaul (IAB) networking is envisioned as a key technology to support more flexible and dense deployment of base stations (BSs). However, existing directed acyclic graph (DAG) based IAB networking highly limits the flexibility and efficiency of link scheduling, due to the fixed parent-to-child relation between two adjacent IAB ...

Network Coding for Integrated Access and Backhaul Wireless Networks
2020 29th Wireless and Optical Communications Conference (WOCC), 20205G new radio (NR) requires a very dense deployment of cellular infrastructure, which poses a great economical challenge if traditional fiber backhaul links are used. To cope with this problem, 3GPP introduced integrated access and backhaul (IAB), aiming to use wireless backhaul to provide high capacity and great deployment flexibility.

Lightening Backhaul Load for Aerial Multi-Hop Integrated Access and Backhaul Networks
IEEE Wireless Communications LettersWe explore aerial multi-hop integrated access and backhaul (IAB) networks, considering the backhaul link load and interference. We propose the lightening backhaul load (LBL) scheme to improve the performance of networks. Specifically, by using the proposed scheme, unnecessary large hop transmission is avoided, which reduces the load at backhaul links ...
