Abstract

A method, performed by a network node. The method is for handling a switch of a wireless device from a source to a target link. The network node and the device operate in a wireless communications network. Given a configuration of the target link indicating resources to perform random access to the network node during the switch, the network node, transmits, prior to the switch, an indication to the device. The indication indicates an update to the configuration. The network node changes the configuration of the target link, based on the update. The changing is performed only after receiving a confirmation of at least one of: i) from the device, that the device has received the indication, and ii) from a first network node operating in the wireless communications network, that it has transmitted the indication to the device.
