Summary

The emerging 5th generation (5G) cellular systems raise unprecedented requirements on data rates, link reliabilities, end-to-end (E2E) latencies, and the support of a portfolio of different scenarios and service types. To satisfy 5G requirements, cutting-edge technology components are proposed both in academia and in industry. The design and evaluation of these technology components demand an accurate and efficient channel model. The most widely used channel model family is the well-known 3rd Generation Partnership Project (3GPP), spatial channel model (SCM) and Wireless World Initiative New Radio phase II (WINNER II) family, which follows the geometry-based stochastic channel model (GSCM) approach. This chapter describes core features of new channel models, such as path loss model, line-of-sight (LOS) probability modeling, outdoor-to-indoor (O2I) penetration loss modeling, and fast fading modeling. It also introduces additional features of new channel models, such as the modeling of large antenna arrays, blockage, scattering, and so on.
