To mitigate interference on cell-edge users and improve fairness of the whole system, dynamic inter-cell interference coordination (ICIC) is one of the promising solutions. However, traditional dynamic ICIC is considered as an NP-hard problem and power variability further adds another dimension to this joint optimization issue, making it even more difficult to quickly reach a near-optimal solution...
Dynamic interference coordination has been widely studied and the core coordination algorithm is the keypoint to determine its performance. However, there lacks a complete performance evaluation of existing coordination algorithms in the literature. This paper focuses on average utility, fairness, and time complexity of various algorithms in homogeneous and heterogeneous 2-cell scenarios. We find...
Along with the fast development of the Internet of Things, the number of wireless communication devices increases rapidly in the near future, leading to very high time complexity for interference coordination, hence traditional schemes do not work properly anymore. To solve this problem, grouping scheme was proposed, which largely decreases the time complexity without obviously degrading the average...
