Revisiting Scheduling and User Association in Heterogeneous Networks When the Backhaul Links are of Limited Capacity
Speaker(s) : Catherine Rosenberg (U. Waterloo, Canada)We present a study on the impact of the limited capacity of backhaul links on user scheduling, and user association in a heterogeneous cellular network. We show that the backhaul limitations have a critical impact on user scheduling, but a minor impact on user association. We propose backhaul-aware user scheduling schemes that are computationally simple and hence easy to implement, and yet can perform very well. We also propose online backhaul-unaware user association rules that are very efficient. These results are significant since they impact the way base stations and user equipment should be designed.
