Zusammenfassung:A wireless device and a method therein for enabling a single Random Access (RA) preamble to be received by a first Access Node (AN) and by a second AN, which first and second ANs are asynchronous ANs. The wireless device, and the first and second ANs are operating in a wireless communications network. The wireless device receives a first signal from the first AN and a second signal from the second AN. Based on the received first and second signals, the wireless device determines an overlapping time window during which a transmission from the wireless device is receivable by the first and second ANs, and transmits a single RA preamble to the first and second ANs during the determined overlapping time window.
