A delay-aware scheduling algorithm for enhancing video services QoS in LTE system

Multimedia services are carried by data packet in LTE (Long Term Evolution, LTE) system, such as voice, video, and so on. Quality of Service in multimedia services is essential to user experience. In this paper, we present a packet scheduling algorithm to improve the performance of video traffic. By considering the number of packet loss and packet delay in the buffer, the priority of each user can be adjusted dynamically to reduce the packet loss rate and maximize system throughput. The results show that compared with the current typical packet scheduling algorithm, the proposed algorithm can significantly improve the packet loss rate, fairness, throughput and other performance.
