A method of controlling radio transmission in a wireless communication network, the method comprising: an access node (100-A; 700; 800) of the wireless communication network receiving an indication from a further access node (100-B; 500; 800) of the wireless communication network, the indication indicating a start time and an end time of a radio transmission performed by the further access node (100-B; 500; 800) on a set of radio resources; based on the indication, the access node (100-A; 700; 800) determining a time which is not overlapped by the radio transmission performed by the further access node (100-B; 500; 800); the access node (100-A; 700; 800) initiating a listen-before-talk procedure at the determined time, the listen-before-talk procedure comprising 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 transmission on the set of radio resources; in response to the radio transmission performed by the further access node (100-B; 500; 800) having a lower priority than the further radio transmission performed by the access node (100-A; 700; 800), the access node (100-A; 700; 800) determining the time as a time before beginning of the radio transmission performed by the further access node (100-B; 500; 800); and/or in response to the radio transmission performed by the further access node (100-B; 500; 800) having a higher priority than the further radio transmission performed by the access node (100-A; 700; 800), the access node (100-A; 700; 800) determining the time as a time after completion of the radio transmission performed by the further access node (100-B; 500; 800). an access node (100-A; 700; 800) of the wireless communication network receiving an indication from a further access node (100-B; 500; 800) of the wireless communication network, the indication indicating a start time and an end time of a radio transmission performed by the further access node (100-B; 500; 800) on a set of radio resources; based on the indication, the access node (100-A; 700; 800) determining a time which is not overlapped by the radio transmission performed by the further access node (100-B; 500; 800); the access node (100-A; 700; 800) initiating a listen-before-talk procedure at the determined time, the listen-before-talk procedure comprising 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 transmission on the set of radio resources; in response to the radio transmission performed by the further access node (100-B; 500; 800) having a lower priority than the further radio transmission performed by the access node (100-A; 700; 800), the access node (100-A; 700; 800) determining the time as a time before beginning of the radio transmission performed by the further access node (100-B; 500; 800); and/or in response to the radio transmission performed by the further access node (100-B; 500; 800) having a higher priority than the further radio transmission performed by the access node (100-A; 700; 800), the access node (100-A; 700; 800) determining the time as a time after completion of the radio transmission performed by the further access node (100-B; 500; 800). <EOS>
