Abstract: An access node (100-A) of a wireless communication network receives an indication from a further access node (100-B) of the wireless communication network. The indication indicates a timing of a radio transmission (20A, 20B) performed by the further access node (100-B) on a set of radio resources. Based on the indication, the access node (100-A) determines a time which is not overlapped by the radio transmission (20A, 20B) performed by the further access node (100-B). Further, the access node (100-A) initiates a listen-before-talk procedure at the determined time. The listen-before-talk procedure comprises detecting whether there is an ongoing radio transmission on the set of radio resources and, in response to detecting that there is no ongoing radio transmission on the set of radio resources, performing a further radio (20A) transmission on the set of radio resources.
