A True Bayesian Estimate concept in LTE downlink scheduling algorithm

Demands for multimedia application have been raised in the current technology era. Multiple simultaneous users may be streaming video or using VoIP call. Thus a better solution to ensure the QoS satisfaction for LTE downlink needs to be designed. Existing algorithm such as Modified Largest Weighted Delay First (MLWDF) have been widely used to cope with the situation arise. Still the need to inquire a more focused multimedia scheduler is there. Incorporating one of the Bayesian elements, True Bayesian Estimate (TBE) is used for the key design of a new downlink scheduler. The simulation results shown that TBE have a more focused scheduling which resulted better throughput, lesser delay and lesser packet loss, for both video and VoIP compared to well-known MLWDF.
