Abstract

The next generational wireless system require ubiquitous access to the huge volume of data. An interesting observation is that small cells, mm-Wave, and massive MIMO can orchestrate a blueprint of a high-capacity wireless system. We will propose a new cellular system architecture, in which mm-Wave small cells with massive MIMO for the 5G use case of broadband access providing Gbps data rate. The millimeter-wave band, is very attractive for the bandwidth-hungry 5G system. However, since different mm-Wave frequencies have different propagation conditions, how many small cells should be deployed is an issue. In this paper, we use ray-tracing based model to analyze the performance of mm-wave multi-cellular systems in a real scenario and give suggested number of small cells for guaranteeing different QoS. In addition, the directive property and high absorption by blockage of mmWave reveal the importance of LoS propagation conditions. Hence, we propose a grid strategy for mm-Wave small cell deployment to ensure the LoS scenario available for most of users. Simulation results show that this deployment strategy is especially effective when small cells are not-so-ultra dense.
