to 450 MHz–1 GHz bands, developing 3D channel models [31] and enriching the propagation sce-
narios. The newly developed models are based on a generic channel modeling approach that enables
the variation of the number of antennas, their congurations, geometry, and antenna beam patterns
without changing the basic propagation model. Applying this approach allows the use of the same
channel data in different link-level and system-level simulations. The nal set of the WINNER chan-
nel models has been described in [17]. The WINNER model has been compared with other reference
models, such as the 3GPP SCM [19] and COST 273 [32] models in [33,34].
