This paper presents a channel model for the fifth generation (5G) air interface evaluations. The described model covers frequency bands from typical cellular frequencies up to millimetre waves and a variety of different environments, with emphasis on the urban outdoor. The model enables assessment of single radio links with, e.g., the massive multiple-input-multipleoutput (MIMO) and very large antenna arrays, device-to-device (D2D) links with both link ends moving, up to system level evaluations with a multitude of different types of transceivers. In addition to the overview some selected model features are described in more detail. Also few exemplary model outputs are depicted and discussed. A comparison to corresponding geometry based stochastic model (GSCM) is performed in urban outdoor environment with the second moment distributions of propagation parameters and with the multi-user (MU) MIMO sum rate capacity. The simulations indicate substantial differences in MU-MIMO performances between the models.
