A New Long Term Evolution Downlink Delay Based Lean Scheduler

M. I. Saglam, A. Kavas and M. Kartal

Abstract: A new delay‐based long‐term evolution scheduler is proposed in this paper. The scheduler allows sharing of radio and base station resources between different radio bearers. It provides a trade‐off between user fairness and system performance. The proposed algorithm is based on the scheduler having knowledge of the age of real‐time (RT) applications packets. By considering the age of the packet with the lean production concept, the scheduler can determine different types of RT application packets and must be scheduled within their packet delay budget. The proposed algorithm is called the delay‐based lean scheduler (DBLS). Simulation results shows that the proposed DBLS algorithm provides superior throughput and delay performance to the modified largest weighted delay first (M‐LWDF) algorithm irrespective of the number of users. © 2018 Institute of Electrical Engineers of Japan.
