Systems and methods related to automatic neighbor relation in a wireless communication network are disclosed. In some embodiments, a method of operation of a User Equipment (UE) to assist a base station in a wireless communication network with automatic neighbor relation comprises receiving reference signal configurations for a plurality of cells and a measurement report triggering criterion. The reference signal configurations are configurations for reference signals to be used by the UE for Radio Resource Management (RRM) measurement reporting for the plurality of cells. The measurement report triggering criterion is related to detection, by the UE, of an unknown cell while performing measurements in accordance with the reference signal configurations for the plurality of cells, where an unknown cell is a cell other than the plurality of cells for which the UE has received the reference signal configurations. The method further comprises detecting an unknown cell and sending a report.
