Abstract

We reduced parameters of the Quasi-Deterministic channel propagation model, recently adopted by the IEEE 802.11ay task group for next-generation Wi-Fi at millimeter-wave, from measurements collected in an urban environment with our 28 GHz directional channel sounder. In the process, we extended clustering of channel rays from the conventional angle and delay domains to the location domain of the receiver – to our knowledge, we were the first to do so – over which the measurements were collected. By comparing channel realizations from the model to realizations from a leading commercial raytracer, we demonstrated that the model effects no detriment to accuracy while maintaining the benefit of significantly reduced complexity.
