Abstract :
Coordination of the multiple base stations by user and beam scheduling can be considered as a promising means of mitigating the inter-cell interference in future cellular networks. Due to the complexity of joint user and beam scheduling problem, its optimal performance has never been revealed yet. In this paper, we investigate its sub-optimal performance by employing genetic algorithm (GA), which can be a practical performance bound to be compared with the existing solution, e.g., by greedy algorithm.
