Coordinated Inter Cell Interference Avoidance Techniques and Performance Parameters for Cross Layer Interference in LTE-A Network

The aim of the paper is to discuss and analyze the recent solutions based on coordinated Inter Cell Interference (ICI) techniques premeditated by researchers. The most thriving need of improved spectral density and user data throughput demands dense deployment of base stations and simultaneous resource allocation in same geographical area. This approach eases the problem of spectrum scarcity but increases ICI drastically. The higher generations of wireless network demand support of real time applications like video streaming, interactive online gaming, on demand data streaming and many more. To support these applications, wide bandwidth is essential. The 4th generation (4G) based on Long Term Evolution (LTE), advance releases (Rel 12 and 13) of LTE (LTE-A) and proposed 5th generation(5G) wireless networks focuses on the key parameter of higher system spectral efficiency to support simultaneous users with high peak bit rate. Inter Channel Interference (ICI) is the result of dense channel assignment in multi-layered network which causes drastic degradation in channel throughput. Being the most urgent need, enhanced ICI coordination (eICIC) methods encourage researchers to meet new technical challenges. This paper emphasis on frequency- time coordination based ICI avoidance methods for downlink transmission i.e., cross layer interference between femtocell base stations (HeNB) to Macrocell base station (MeNB). We present other interference coordination methods for understanding of multifaceted views of researchers. At the end of the paper performance parameter matrix for ICIC methods is described.
