Abstract
A first Network Node (NN) 206 and a method therein for enabling handover of a first and a second wireless device 210,212 from the first NN to a second NN 208. The first NN determines that the second wireless device is to refrain from transmitting an uplink synchronization signal. Based on the determination, the first NN configures the first wireless device to transmit an uplink synchronization signal and to synchronize to a first downlink synchronization signal, an configures the second wireless device to synchronize to a second downlink synchronization signal. The first NN receives, from the second NN, information relating to a measurement performed on the uplink synchronization signal transmitted only from the first wireless device. Based on the received information, the first NN requests the second NN to perform the handover of the first and second wireless devices.
