Optimal Resource Allocation for O-RAN With Integrated Access and Backhaul

IEEE Open Journal of the Communications Society
We propose a resource allocation optimisation framework that integrates the O-RAN architecture with out-band Integrated Access and Backhaul (IAB). Using mixed-integer linear programming (MILP), we coordinate multiple control functions across O-RAN to ...

Delay and Utilization Analysis of Roadside 5G NR IAB Deployments With Half-Duplex Constraints

IEEE Open Journal of the Communications Society
The standardized 3GPP integrated access and backhaul (IAB) technology is expected to provide a cost-efficient densification of 5G New Radio access networks. Relying on multi-hop communications, one of the critical metrics in such a system is latency.

Beamforming Design for Cache-enabled Integrated Access and Backhaul Networks

, 2022
In this paper, we consider a cache-enabled integrated access and backhaul (IAB) network. We first derive the sum achievable data rate. Then, we formulate the sum achievable data rate maximization problem with respect to (w.r.t.) the beamforming designs ...
