摘要

A method of operating a network node (101) of a communication network (100) comprising a plurality of network nodes (101 to 104) communicating via a plurality of communication channels (105 to 107), the method comprising counting down a pre¬ determined waiting time (301) before transmitting a signal (304) via a selected one of the communication channels (105), detecting, during the counting down, whether the selected one of the communication channels (105) becomes busy, and, in case that the selected one of the communication channels (105) becomes busy during the counting down, switching to another one of the communication channels (106) and continuing the counting down on the other one of the communication channels (106).
