Abstract

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 also gives an overview of how the power is dispensed to the users at minor group and major group regions Methods: ICIC has one of the schemes which is based on reusing the frequency called as Fractional Frequency Reuse (FFR). There are different techniques of FFR. They are Partial Frequency Reuse (PFR), Soft Frequency Reuse (SFR) and Soft Fractional Frequency Reuse (SFFR). Findings: In this survey it is found that, the different techniques of FFR gives different throughput and it is also found that SFFR scheme gives the highest throughput when compared with others. Applications: The different techniques of FFR can be used in LTE (Long Term Evolution) based networks. The users will get benefitted based on different power allocations. The real time applications of this technique can be seen in 4G networks.
