Abstract

Modern as well as future features of cellular radio networks rely on cooperation between base-stations. Such cooperation is even more pronounced in cloud radio access networks where fronthaul/backhaul pipes play a central part in the cloud based processing.


Physical layer secrecy features, based on concepts of the classical wiretap channel, are now considered in different wireless networks. In this research we study via an information theoretic perspective the impact of physical layer security demands on simple cellular (Wyner type) communications networks.


The secrecy demands are imposed on the individual cell sites (radio-units, base stations). Specifically, we address the tradeoff between reliable communication rates on the uplink, secrecy performance (equivocation-rate tradeoff) and fronthaul links capacities.
