"Virtual Cell Deployment Areas" and "Cluster Tracing" - new methods for directional channel modeling in microcells

We propose a new method for the simulation of microcellular propagation channels, which includes both deterministic and stochastic aspects. First, the geometrical layouts of 'typical' deployment areas, called 'Virtual Cell Deployment Areas' (VCDA), as well as routes of the mobile station (MS) through the VCDA, are defined. Then, the delays and directions-of-arrival of multipath clusters can be traced by geometrical means. Finally, the small-scale fading within the clusters is modelled stochastically. This approach was adopted by the COST259 DCM, the standard model for directional wireless channels.
