LTE: An enhanced hybrid domain downlink scheduling

The third Generation Partnership Project (3GPP) has successfully launched 4G data on mobile communication by utilizing the Long Term Evolution (LTE). The multimedia processing such as video calling/conferencing, video transmission/reception in mobile communication are in need of multiple user support, speed, high data transmission rate, low data loss rate and high throughput. In this paper an enhanced scheduling algorithm known as, EM-LWDF (Modified Largest Weighted Delay First) is proposed in combination of time/frequency scheduling for LTE. The proposed scheduling algorithm is evaluated under various simulation scenarios and compared with conventional algorithm such as PF, M-LWDF, EXP/PF, and proposed +LWDF. The evaluation is made in terms of system throughput, fairness index and Packet Loss Rate (PLR) and the evaluation results shows that the proposed scheduling algorithm shows remarkable performance improvement.
