Webbfairness, stability and throughput optimality. The two most commonly used scheduling algorithms based on throughput and user fairness in video communication are RR and PF scheduling algorithms [3]. The RR scheduling algorithm maintains a constant delay between two transmissions to the same user. WebbA. Proportional Fairness Scheduler The objective of the PF scheduler [8] is to ensure balance between cell throughput and user fairness. This scheduling policy has been adopted in the majority of papers dealing with NOMA [2], [4]. The scheduler keeps track of the average throughput T k(t) of each user in a past window of length t c, where t programming business rules
