摘要：The proportional fair (PF) scheduling algorithm compromises between cell throughput and fairness. Manyresearch findings have been published by various researchers about PF algorithm based on mathematicalmodel and simulations. In this paper we have taken the practical route to analyse the algorithm based onthree types of subscription. In this benchmarking study, the user subscriptions are differentiated as Gold,Silver and Bronze schemes and they are provisioned with certain throughputs. Apart from subscriptionsplans, the channel condition also plays a major role in determining the throughput. So in order to ensurefairness among different subscriptions even in the bad channel conditions and to deliver the provisionedthroughputs certain priorities are attached with the subscriptions. As per the subscription plans Goldsubscribers are assigned with 50% of the speed offered by the network as maximum based on CAT3 speed(100 Mbps in DL and 50 Mbps in UL), Silver is assigned with 25% of the max speed and Bronze isassigned with 12% of the max speed. The priorities assigned to subscribers determines the fairness in theunfavourable channel conditions - Bronze (high), Silver and Gold (medium). In this paper, anbenchmarking tests have been performed with all of three types of subscribers for nearly two hours in thelive single cell network without any heterogeneous cells influencing it. Furthermore, the results arecompared with the simulation results.
