Abstract: Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit a handover error report to an access node. An access node may use information in the handover error report to adjust configurations for parameters that are used to make handover decisions. A UE may transmit such a handover error report in response to an undesirable handover procedure from a source access node to a target access node, such as a failed or nearly failed or too early handover procedure. The UE may transmit this handover error report to either the source access node or the target access node or another node.
