Study of Downlink Scheduling Algorithms for Real-time multimedia services in LTE networks

Abstract

Long Term Evolution (LTE) is one of the fastest growing technologies which supports variety of applications like video conferencing, video streaming, VoIP, file transfer, web browsing etc. In order to support multiple applications, Radio Resource Management (RRM) procedure is one of the key design roles for improving the system performance. LTE system effectively utilizes the resources by dynamically scheduling the users in both frequency and time domain. However, scheduling algorithms are not defined in the Third Generation Partnership Project (3GPP) specifications. Therefore, it becomes one of the special interests for service providers. In this paper, Radio Resources Management in LTE networks was studied and presented. Finally, an analysis of six (6) existing downlink scheduling algorithms that mainly focus on real-time multimedia services was carried out
