Simple Feedback with Priority List Radio Resource Scheduling Scheme for 3GPP LTE Networks
Self organizing network (SON) techniques, algorithms and eventually standards are critical steps in long term evolution (LTE) femtocell deployments. Third generation partnership project (3GPP) standardizes self-optimizing and self-organizing capabilities for LTE in order to provide the upcoming requirements of broadband mobility, development of SON, inter cell interference (ICI) elimination, fairness, and quality of service (QoS). The need of intelligent radio resource management (RRM) allows the network to have a full control over services and the physical radio blocks (PRBs). These features should be deeply studied under designing the signaling protocols and RRM algorithms. In this paper, important radio resource scheduling aspects are discussed. New feedback scheme for channel quality information (CQI) and a new PRBs scheduling method using a priority list created by the RRM algorithm are introduced satisfying the predefined requirements of the RRM in 3GPP LTE networks.
