In recent years the Worldwide Interoperability for Microwave Access (WiMAX) and Long
Term Evolution (LTE) networks have become rapid growing technologies in 4th Generation …

Cellular networks are expanding massively due to high data requirements from mobile
devices. This has motivated base station densification as an essential requirement for the …

Fractional Frequency Reuse (FFR) has been accepted as a technique by many researchers
in recent years to overcome the inter-cell and co-channel interferences from neighboring …

The frequency reuse technique is a fundamental and classical issue in the interference
management of cellular networks, and has never experienced any fundamental shifts from …

Abstract Long Term Evolution Advanced (LTE-A) technology is considered as the most
possible candidate for next generation mobile communications. LTE-A networks offer high …

Fractional frequency reuse for the downlink of multicellular WiMAX networks is examined in
this work. Three different schemes are evaluated through simulations, including distance …

The current WiMAX operators have to choose whether to utilize reuse-1 (R-1) or reuse-3 (R-
3) frequency planning pattern. The R-1 pattern achieves high spectral efficiency but results …

Heterogeneous network (HetNet) is a promising cell deployment technique where low
power access points are deployed overlaid on a macrocell system. It attains high throughput …

Objectives: This paper gives survey of different techniques and the overview of how the
bandwidth is dispensed to the users at the major/edge regions and minor/center regions. It …

Abstract Fractional Frequency Reuse (FFR) is a key concept for increasing the spectral
efficiency of OFDMA-based broadband wireless access systems such as Mobile WiMAX …
