1. A method performed by a network node for validating minimization of drive test (MDT) reports, the method comprising:
receiving a MDT report generated by a wireless device;
determining to perform validation on the received MDT report;
correlating the MDT report with MDT reports from one or more wireless devices in proximity to the wireless device to determine a first correlation value;
determining a trust score for the MDT report based on one or more correlation values, the one or more correlation values at least comprising the first correlation value;
determining whether the trust score is below a validation threshold; and
upon determining the trust score is below the validation threshold, performing a corrective action with respect to the received MDT report.
