Alternative Concept for Geometry Factor of Frequency Reuse in 3GPP LTE Networks

摘要

An intelligent radio resource management (RRM) is the core system of long term evolution (LTE) networks to provide the upcoming future applications with the broadband mobility, development of self organizing network (SON), and quality of service (QoS). Third generation partnership project (3GPP) standardizes that every 1 ms the physical radio resource blocks (PRBs) should be rescheduled during the transmission time interval (TTI). This proposal places a lot of processing load in the evolved node B's (eNodeBs). The way to speed up the scheduling process should be considered in addition to increasing the whole LTE network throughput caused by utilization of high order modulation. It requires more processing time on both ends of the transmission process. In this article, important radio resource scheduling aspects are discussed. An alternative concept for geometry factor based on a new feedback method of channel quality information (CQI) can be used to employ the determined frequency reuse policy among the LTE cells. The presented concept helps us to reduce the PRBs scheduling time, processing load, and complexity.
