Interference mitigaion between femtocell and macrocell

Femtocell is no longer a new concept to the public in the 21st century, which witnesses the tremendous advancement of high-tech. In terms of interference mitigation between networks, particularly, there are already a large amount of available measures, such as hybrid spectrum usage and self-optimizing that make great contribution to network optimization. This paper illustrates three types of interference in the cooperation of macro-femto cells from the aspect of the efficient spectrum utilization. Meanwhile, we also introduce an advanced version of Femtocell called Attocell, which shows the advantages of next generation Femto-communication by comparison.
