A method in a radio network node for determining whether a wireless device is a suitable candidate for handover to a target cell for load balancing reasons. The radio network node serves a source cell. The method includes determining a first level of coverage of the target cell based on a first measurement report. The method further includes storing measurement data obtained from a second measurement, being at least one of a layer 2 and a layer 1 measurement. The method further includes establishing a correlation between the determined first level of coverage and the stored measurement data and updating statistical data based on the established correlation. The method further includes determining whether the wireless device is a suitable candidate for handover to the target cell for load balancing reasons, based on the updated statistical data.

The present disclosure concerns movements, such as handovers, of user equipments (UEs)-from one radio cellto another radio cell. Disclosed herein are methods as well radio network nodes. A radio network nodemay, for example, select the most suitable UE(s)-to move from a source radio cellto a target radio cellin case the traffic load in the source radio cellis below or equal to the traffic load of the target radio cell. Hereby it is made possible to improve the resource utilization.

A method and network node () for supporting evaluation of usage of a radio network feature in radio communication between wireless devices () and the network node. The network node () retrieves (4:1) statistical information regarding the usage of the radio network feature, and reports (4:5) the statistical information to an Operation and Maintenance, O&M, node (). The O&M node then uses (4:6) the statistical information for evaluating how measured performance (4:3) of the radio network is related to the usage of the radio network feature.
