Abstract

This chapter outlines the methods to capture and characterize the blockage effects in cellular millimeter-wave (mmWave) systems together with the state-of-the-art techniques to mitigate the negative effects of dynamic blockage on both user- and network-centric performance indicators. It first discusses the key aspects of mmWave signal blockage by various objects in urban deployments and its consecutive impact on link-level performance. Further, the chapter summarizes mathematical methods to model the dynamic blockage processes in different Internet-of-Things (IoT) scenarios and deployment configurations, such as massive augmented and virtual reality setups, connected vehicles, etc. The presented results can be used in design and optimization of cellular mmWave systems for the emerging delay-, availability-, and reliability-sensitive services across many 5G verticals. The chapter also addresses possible solutions to mitigate blockage in large-scale 5G-grade consumer IoT deployments equipped with mmWave New Radio connectivity.
