Distinguishing Micromobility and Blockage in 6G Sub-THz Systems: A Machine Learning Approach

open access: yesIEEE Open Journal of the Communications Society
Dynamic human body blockage and user equipment (UE) micromobility in the hands of a user are two impairments that may lead to connectivity losses in 5G millimeter wave (mmWave, 30-100 GHz) and 6G sub-terahertz (sub-THz, 100-300 GHz) systems.
