碩士 === 國立交通大學 === 電信工程研究所 === 103 === In this thesis, we consider the dynamic user scheduling in each time slot based on maximizing the minimum rate among all the selected users such that the scheduling time is as short as possible in a Cloud-RAN with multiple single antenna RRHs and multiple single antenna MUs framework. Without doing beamforming, the framework becomes a point-to-point wireless network, where a MU treats the interference from other RRHs, not its serving RRH, as noise. Then we need to choose MUs and decide the pairing relationship between RRHs and UE appropriately such that the max-min SINR is as high as possible. And we propose two heuristic ways to schedule. With doing beamforming, although all the MUs can be served simultaneous in a time slot, some MUs with bad channel conditions may suppress the total throughput and may be a burden to shorter scheduling time. Hence, we somehow abandon the burden in a time slot for better total throughput. It brings to the shorter scheduling time at most of time.
