Map-Based Channel Model for Evaluation of 5G Wireless Communication Systems

This paper presents a channel model for the fifth generation air interface evaluations. The described model covers frequency bands from typical cellular frequencies up to millimeter 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-multiple-output (MIMO) and very large antenna arrays, device-to-device 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, a few exemplary model outputs are depicted and discussed. A comparison to corresponding geometry-based stochastic model is performed in urban outdoor environment with the second moment distributions of propagation parameters and with the multiuser (MU) MIMO sum rate capacity. The simulations indicate substantial differences in MU-MIMO performances between the models.
