摘要：

In this paper, we focus on delivering radio engineers a practical design of macro-micro code division multiple access (CDMA) cellular overlays. First, we review our algorithmic approach to jointly deploy macrocells and microcells over today's big urban areas having spatially nonuniform traffic distributions. Next, we identify several further issues related to the optimal design of macro-micro cellular overlays and enhance the cell-deploying algorithm to reflect these issues. The numerical results by extensive event-driven simulations show that the resulting macro-micro cellular overlays successfully cope with the existing conditions of today's big urban areas, such as spatial and temporal traffic distributions and user mobility characteristics. Finally, we discuss the practical guidelines for designing macro-micro cellular overlays in the existing big urban areas.
