Self-meshed autonomous LTE/LTE-A radio access network for constrained environments

Romain Favraud 1 
Abstract : Military communication systems are nowadays improving slowly compared to commercial systems. In parallel, public safety (ps) communication systems are changing due to emergence of long term evolution (LTE) as a mature solution. However, LTE is initially designed for commercial cellular network and need to be evolved to tackle the requirements of ps use cases. In this thesis, we develop a complete solution to address constrained ps and military use-cases allowing to wirelessly mesh mobile network nodes and to provide access to standard user equipments while only requiring a single radio band. Starting from ps and military use cases, we present the potential scenarios and derive functional requirements for future wireless systems. The constraints applying to these systems lead to the selection of LTE as the radio access technology. We detail the challenges faced by a LTE solution given the state of the art. We present a novel network infrastructure architecture that enables multi-hop LTE mesh networking for autonomous base stations via in-band self-backhauling relying on a new base station: the e2nb. We detail the building blocks of the architecture, we investigate the coordination and orchestration functionality and propose a cross layer hierarchical resource scheduling algorithm in order to efficiently meet quality of service requirements for real-time traffic while maximizing the throughput for elastic flows. We evaluate the self-backhauling interface using open air interface and then evaluate our resource scheduling algorithm in various network topologies and traffic flows. Finally, we summarize the remaining uncertainties concerning real-field deployments.
