A method performed by a source network node serving a wireless device in a wireless communication network, the method comprising: measuring a received signal power based on a received uplink signal from the wireless device, - determining a second normalised Signal to Interference and Noise Ratio, SINR, associated with the measured received signal power, wherein an uplink signal quality of the received signal is deemed poor when the second normalised SINR for the source network node is below a predefined threshold, - requesting the wireless device to perform a measurement on a possible target network node and the source network node, when the second normalised SINR for the source network node is below the predefined threshold, - obtaining a measurement report from the wireless device comprising the performed measurement on at least the possible target network node, the performed measurement indicating received signal strength for a signal received from the possible target node, the obtained measurement report further comprising a received signal strength for signals received from the source network node, - determining a first normalised SINR based on the received signal strength as measured by the wireless device for signals received from the source network node and based on an average noise and interference as measured by the source network node, and - providing, to the possible target network node, the determined first normalised SINR associated with the received signal strength for the source network node and the received signal strength of the possible target network node as received in the measurement report from the wireless device, - obtaining an indication from the possible target network node indicating whether the target network node is a better option than the source network node for serving the wireless device. - determining a second normalised Signal to Interference and Noise Ratio, SINR, associated with the measured received signal power, wherein an uplink signal quality of the received signal is deemed poor when the second normalised SINR for the source network node is below a predefined threshold, - requesting the wireless device to perform a measurement on a possible target network node and the source network node, when the second normalised SINR for the source network node is below the predefined threshold, - obtaining a measurement report from the wireless device comprising the performed measurement on at least the possible target network node, the performed measurement indicating received signal strength for a signal received from the possible target node, the obtained measurement report further comprising a received signal strength for signals received from the source network node, - determining a first normalised SINR based on the received signal strength as measured by the wireless device for signals received from the source network node and based on an average noise and interference as measured by the source network node, and - providing, to the possible target network node, the determined first normalised SINR associated with the received signal strength for the source network node and the received signal strength of the possible target network node as received in the measurement report from the wireless device, - obtaining an indication from the possible target network node indicating whether the target network node is a better option than the source network node for serving the wireless device.
