Abstract

Embodiments of an Evolved Node-B (eNB) and method for collecting and reporting data related to a coverage area in a wireless network are generally described herein. The eNB may be configured to track geographic bin information for one or more User Equipment (UEs). The eNB may comprise hardware processing circuitry configured to, for each of the UEs, measure an angle of arrival for the UE and a propagation delay for the UE, and to select a geographic bin for the UE from a set of candidate geographic bins. The hardware processing circuitry may be further configured to send, for each of the candidate geographic bins, performance data for the candidate geographic bin to the TCE when a number of UEs for which the candidate geographic bin is selected is not less than a UE distribution threshold.
