Fair Coexistence of Scheduled and Random Access Wireless Networks: Unlicensed LTE/WiFi. IEEE/ACM Transactions on Networking, 25(6), 3267–3281.1063-6692https://hdl.handle.net/10016/33683We study the fair coexistence of scheduled and random access transmitters sharing the same frequency channel. Interest in coexistence is topical due to the need for emerging unlicensed LTE technologies to coexist fairly withWiFi. However, this interest is not confined to LTE/WiFi as coexistence is likely to become increasingly commonplace in IoT networks and beyond 5G. In this paper, we show that mixing scheduled and random access incurs an inherent throughput/delay cost and the cost of heterogeneity. We derive the joint proportional fair rate allocation, which casts useful light on current LTE/WiFi discussions. We present experimental results on inter-technology detection and consider the impact of imperfect carrier sensing.15eng© 2017, IEEE.CoexistenceSpectrum sharingUnlicensed LTELTE-ULAA-LTEWifiCSATLBTLBEProportional fairnessresearch articleTelecomunicacioneshttps://doi.org/10.1109/TNET.2017.2731377open access326763281IEEE/ACM Transactions on Networking25AR/0000020886
