Perspectives of Geometry Based Deterministic Reference Channel Models for 5G Applications

Geometry based reference channel models (GBRCM) have been one of key topics of radio channel modelling for years. Their development and applications have been bringing the academy, industry and standardization bodies together in several large projects, such are 3GPP, WINNER, METIS, etc. With 5G as an ongoing process, it is important to continue and adapt GBRCM research to new arriving technologies and applications. This paper discusses perspectives of geometry based deterministic reference channel models (GBDRCM), a subset of GBRCM, for 5G reference channel models, focusing on some key concepts of 5G: massive MIMO, Internet of Things and resources. The main hypothesis lies on the concept of deterministic reference channel models as an alternative for the commonly accepted stochastically based geometry based RCMs. The proposed solution is based on the concept of ray entity delivered from ray tracing simulations.
