Joint MUD Exploitation and ICI Mitigation Based Scheduling With Limited Base Station Cooperation
In this paper, the authors propose a novel opportunistic scheduling algorithm in multi-cell cooperation scenario, i.e., joint Multi-User Diversity (MUD) exploitation and Inter-Cell Interference (ICI) Mitigation based scheduling (MEIMS). Their algorithm jointly considers the intended channel condition of the scheduled user from its serving cell and the orthogonality between that and the corresponding interference channels to concurrently scheduled users in neighboring cells so as to exploit MUD and mitigate ICI simultaneously. The performance of their algorithm is evaluated through simulation. Results show that, their scheme can significantly enhance the received Signal to Interference plus Noise Ratio (SINR) with relatively better fairness guarantee, thus achieves the largest throughput and utility comparing to several well-known scheduling algorithms.
