Abstract
The present disclosure relates to methods and arrangements for performing wireless device assisted handover form a source access node to a target access node. Performed in a wireless device, a method comprises performing (S) one or more mobility measurements for corresponding candidate radio links and selecting (S), from the one or more candidate radio links, an initial target link based on the performed one or more mobility measurements. A first radio link measurement report based on the one or more mobility measurements, identifying the initial target link is transmitted (S) to a target node providing the initial target link, using a first radio link reporting mechanism. A second radio link measurement report for the one or more candidate radio links and based on the same one or more mobility measurements, is transmitted (S) to the source access node using a second radio link measurement report different from the first radio link reporting mechanism. Finally, a wireless device connection is initiated (S) over a handover target link indicated in a handover command from the source access node or over the initial target link, wherein the wireless device connection is initiated over the initial target link based on a reception status for the handover command.
