The Long Term Evolution (LTE) system is already able to provide a various background of media to mobile users, including multimedia services such as audio, video, data. In fact, the High Speed Downlink Access plus (HSPA+) solution within LTE can greatly enhance bit rates on downlinks. However, the supporting for multimedia applications with different QoS requirements is not devised yet. Hence, in this paper we present an effective packet scheduling algorithm based on proportional fairness (PF) scheduling algorithms for LTE. We optimize traffic class weightings and instantaneous user data rates that are central to packet prioritization approach of packet scheduling. Finally, we evaluated and showed the performance of optimized scheduling algorithm through simulation of multimedia traffics being currently transmitted to users the over LTE links in a multi-cell environment. © 2012 Springer-Verlag.
