Publication number: 20230068437Abstract: A system and method for predicting one or more cellular performance parameters associated with user equipment (UE) within a three-dimensional (3D) space having one or more cellular nodes, the cellular nodes including one or more cellular nodes, including a 5G cellular node. For each of one or more of pieces of UE within the 3D space, determine values associated with one or more UE-side features of each piece of UE. Predict values of the one or more cellular performance parameters for each UE as a function of the values associated with the one or more UE-side features of each respective piece of UE, wherein predicting values of the one or more cellular performance parameters includes applying the values determined for each respective piece of UE to a machine learning module trained using truth data associated with the one or more UE-side features.Type: ApplicationFiled: August 18, 2022Publication date: March 2, 2023Inventors: Arvind Narayanan, Eman Ramadan, Feng Qian, Zhi-Li Zhang
