assumption that the maximum cell radii for microcells and macrocells are 200 and 500 m,
respectively, and that the distribution of user terminals over the cell area is uniform. The median
values are dependent on cell radii, thus the tabulated values are not universal in bad urban scenarios.

4.5 CDL Models
Although the clustered delay line (CDL) model is based on similar principles as the conventional
tapped delay line model, it is different in the sense that the fading process for each tap is modelled in
terms of a sum of sinusoids rather than by a single tap coefficient. The CDL model describes the
propagation channel as being composed of a number of separate clusters with different delays. Each
cluster, in turn, is composed ofa number of multipath components (rays) that have the same delay
values but differ in angle-of-departure and angle-of-arrival. The angular spread within each cluster can
be different at the BS and the MS. The offset angles represent the Laplacian PAS of each cluster. The
average power, mean AoA, mean AoD of clusters, angle-spread at BS and angle-spread at MS of each
cluster in the CDL represent expected output of the stochastic model with parameters listed in Table
4-8. Exceptions are the fixed feeder link models in scenario B5, for which no stochastic models have
been defined.
Parameter tables for the CDL models are given in Section 6 of this document.
