Instant Channel Allocation Technique to Improve System Throughput in Joint LTE Cellular Network

Femtocells can be easily deployed in macrocell LTE network without requiring a centralized planning to provide high data rate connectivity with a limited coverage. Femtocell is low-power, very small and cost effective cellular based station used in indoor environment. Femtocell and Macrocell share same frequency band which cause destructive interference. In order to maintain reliable service of macro-cells, it is most important to mitigate destructive femto to macro interference. Frequency Reuse (FR) is an effort of manipulating the frequency resource allocation upon terminal's location to improve system throughput. In this paper, an efficient method to improve system capacity through interference management in the existing Femto-Macro two tier networks has been proposed. In the proposed scheme, femtocell user will be allocated frequency instantly as it is required. This will also improve system throughput which will effectively control interference between macrocells and femtocells.
