A Spatially Consistent Radio Channel Model Enabling Dual Mobility

In a future radio communication network various types of links will co-exist in the same area, and they need to be modelled consistently. We describe a channel modelling framework, which can consistently describe large and small scale phenomena of different types of links. The approach supports generation of spatially consistent radio channel realization also for cases where both link ends are moving like in device-to-device communication. Traditional cellular links and distributed antenna systems can be described with the same model, which allows a fair comparison between different types of transmission schemes. The main principle of the proposed framework is to create the propagation environment independently from the radios like in COST 2100 model. This is like simplified ray tracing without a map, i.e. without need of any detailed geometric or electromagnetic description of the environment as a prerequisite. The modelling principle and some examples of resulting radio channel statistics are simulated and presented.
