本文给出了公开文献中陆地移动的蜂窝无线通信系统的上行和下行多径到达时间和二维到达方向的三变量联合和边缘分布的第一个封闭形式显式表达式，该表达式是通过彻底的数学严格推导出来的。基于三维（3-D）空间关系的“几何”模型，在移动的站、散射体、和基站。散射体在本文中被建模为在具有以移动的为中心的平坦圆形基底的地上半球中（或者备选地，在球体内）具有均匀的3-D空间分布
This paper presents the open literature's first closed-form explicit expressions of the trivariate joint and marginal distributions of a landmobile cellular wireless communication system's uplink and downlink multipaths' time of arrival and two-dimensional direction of arrival, rigorously derived via thorough mathematics based on a "geometrical" model of the three-dimensional (3-D) spatial relationships among the mobile station, the scatterers, and the base station. The scatterers are herein modeled to have a uniform 3-D spatial distribution in an aboveground hemisphere with a flat circular base (or alternatively, within a sphere) centered at the mobile
