In this RRM the resource is dynamically allotted in distributed and centralized manners so that spectral efficiency is maximized across the entire network. To do this a distinctive interference mapping technique is implemented to assistance with determining whether distributed or centralized mode is relevant per base station. A brand new radio resource management (RRM) technique for enhancing the downlink performance in soft-frequency reuse based lengthy term evolution (LTE) systems is presented. Whenever a distributed approach is granted to some base station it cause the whole spectrum while whenever a centralized approach is imposed on the base station it are only allotted a subset of the spectrum. The suggested then utilizes the confederation conception a feeling that when the allocation approach is determined the individual base stations can seize control of the allocated resource. When coupled with proportional justness scheduling, this RRM may also take advantage of multiuser diversity. Therefore, to be able to implement the SFR approach effectively in LTE heterogeneous cellular systems (Honest), all Smuts have adaptive interference avoidance capacity .It'll be shown through mathematical analysis and computer simulations that this method offers significant enhancements in terms of sum rate and excellence of service by growing the guaranteed data rate per user.
