5G Enhanced Mobile Broadband Downlink Scheduler

Abstract

A new 5G enhanced Mobile BroadBand (eMBB) downlink scheduler is proposed in this paper. 5G can support a diversity of services and user requirements. These services and user requirements can be handled by functions like scheduling, link adaptation and power control. Scheduling has a close relation with other functionalities for an efficient system resources. The proposed 5G eMBB scheduling algorithm is throughput and Channel Quality Indicator (CQI) aware. The proposed algorithm, named 5G eMBB lean scheduler, is inspired by lean production method and possesses the properties of both best CQI and proportional fair (PF) algorithms. According to our best knowledge, lean production method has not been applied to 5G mobile communication scheduling algorithms. The proposed scheduler exceeds the performance of best CQI and PF algorithms in fairness and the throughput respectively even for cell edge users.
