Dynamic Frequency Reuse Factor Choosing Method for Self Organizing LTE Networks

Under the development of the self organizing network (SON) for long term evolution (LTE) systems, the radio resource management (RRM) with suitable frequency reuse technique is a vital factor in providing the required performance for future applications especially in the case of convergence of networks and services. A way to improve the scheduling process of the physical radio resource blocks (PRBs) should be considered to increase the network throughput and to achieve better quality of service (QoS) and fairness to the users. In this paper, some important aspects related to RRM are discussed, and a new channel quality indicator (CQI) concept based on a simple feedback technique is presented. This method creates an alternative vision for the geometry factor to employ the selective frequency reuse technique inside the network cells.
