There is provided a radio measurement procedure for station statistics measurements in wireless communication network. In the method, the requesting station transmits to a requested station a request message for triggered RSNA station statistics measurements including a group identity field which indicates the requested RSNA statistics group and a triggered reporting field for RSNA counters which is used to specify trigger conditions comprising reporting triggers and RSNA statistics thresholds for the corresponding reporting triggers. And, the requesting station receives from the requested station a RSNA statistics measurements report message including measured RSNA statistics for the reporting triggers specified in the triggered reporting field for the RSNA counters when the measured RSNA statistics exceeds the corresponding RSNA statistics thresholds specified in the triggered reporting field for the RSNA counters.
