On the requirements for quasi-deterministic radio channel models for heterogeneous networks

This paper introduces the key aspects of a new channel model based upon the Wireless World Initiative New Radio (WINNER)+ channel model for wireless channels in heterogeneous scenarios (e.g. indoor, outdoor and satellite scenarios). It consists of a collection of features created in the extended spatial channel model (SCME) and WINNER projects along with novel modeling approaches. The quasi deterministic radio channel generator (QuaDRiGa)
¹
is a geometry-based stochastic channel model (GSCM) which provides features to enable quasi-deterministic multi-link tracking of user equipments (UEs) movements in changing environments. The key aspects of QuaDRiGa are geo-correlated parameters maps, three dimensional antenna characteristics, a novel geometric polarization model, continuous drifting of small and large scale effects along UE movement, non-constant velocities as well as transitions between varying propagation scenarios (e.g. line of sight (LOS) and non line of sight (NLOS) conditions). The basic ideas and impacts of the additional features will be presented as well as the importance for future analyses.
