CO-CHANNEL DEPLOYMENT CROSS LAYER APPROACH FOR LTE HETEROGENEOUS NETWORKS

Deepthi Shree A.M, Arun Biradar

Abstract: Nowadays Heterogeneous Networks (HetNets) are envisioned as the major capacity and performance enhancement enablers by means of increasing the spectral efficiency per unit area. In LTE, since pico cells typically share the frequency band as macro cells, the performance of a low-power pico access node could be severely impaired by interference from a high power macro access node. In co-channel deployment it is necessary to balance the load and Share the resources between the different layers, where macro and pico cells share the same carrier frequency. In this case, one of the main problem that need to be addressed in order to improve the network performance is: Cell selection. For this reason we propose a throughput-based cell selection algorithm. This algorithm targets to optimize the throughput of each user
