Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may receive configuration indicative of one or more trigger events for which the UE is to report hyper-frame number (HFN) desynchronization between the UE and a network entity. For example, the configuration information may indicate a threshold quantity of instances of HFN desynchronization such that satisfaction of the one or more trigger events is based on a quantity of instances of HFN desynchronization detected by the UE satisfying the threshold quantity of instances of HFN desynchronization. Thus, the UE may transmit, in accordance with the configuration information, a report indicative of HFN desynchronization based on satisfaction of the one or more trigger events.
