| Summary: | Spectrum scarcity is one of the most discussed restraining aspects in wireless
communication system. To solve this issue Frequency Reuse (FR) concept is introduced. It
is a promising development to fulfil the requirement of Long Term Evolution Advanced
(LET-A). With the introduction of FR comes the problem of Inter Cell Interference as the
neighboring eNodeBs (eNB) which uses the same frequency band that will act as an
interference source. In this paper, a Dynamic Frequency Reuse (DFR) method is
anticipated. Continuous optimization of resource allocation of each cell is considered in
this method. The important focus of the paper is to expand the capacity of the users
placed in cell edge areas by reducing out of cell interference. Simulation has been done to
prove that the proposed scheme leads to efficient resource management. |
