This paper elaborates on the harmonious wireless network from the perspective of interference management. The coexistence of useful signals and interfering signals is beneficial in throughput terms of the entire wireless network. Useful signals and interfering signals are complementary and are in juxtaposition to each other in the context of a single communication link, and are in symbiosis within the framework of the networks. The philosophy behind this could be described by the Chinese traditional culture symbol of “yin” and “yang”. A wireless network having optimal performance must be a harmonious network where the interfering and useful signals harmoniously coexist in an optimal balance. Interference management plays a critical role in achieving this optimal balance, while sophisticated interference management techniques should be designed to improve the system performance.
