Abstract:
Cell range extension (CRE) has been used as a method to increase the area under the small cell and balance the loads between small and large cell by adding a cell selection offset (CSO) to small cells in heterogeneous network deployment.
Previously most of the other literatures considered CSO setting for round robin resource scheduling but in this study we have considered Proportional Fair Resource Scheduling to make the computations realistic.
This work paves a way to achieve better load balancing by selecting a CSO value to have equal average cell data rates by means of proportional fair resource scheduling in LTE HetNets. Simulation results indicate that this method can achieve a better average user throughput in networks with different densities of small cells
