Abstract: Methods for communicating a Quality of Experience (QoE) measurement are provided. In embodiments disclosed herein, a wireless device communicates the QoE measurement to a base station based on Radio Resource Control (RRC) segmentation. In this regard, the wireless device receives an indication that indicates whether the base station can support the RRC segmentation. Accordingly, the wireless device transmits the QoE measurement to the base station based on the RRC segmentation if the indication indicates that the base station can support the RRC segmentation. By transmitting the QoE measurement based on the RRC segmentation, the wireless device can communicate more QoE information to the base station in a larger QoE measurement file (e.g., 8000 kilobytes).

The source node sends (1004), to a target node for conditional handover of the UE, a conditional handover request that includes one or more parameters indicative of a likelihood that handover of the UE to the target node will be executed. The target node receives (1102) the request and parameters and allocates (1104) resources for the UE, taking into account the likelihood that handover of the first UE to the target node will be executed. The target node sends (1106) handover configuration information for the first UE to the source node, in response to the conditional handover request.
