摘要
An access node (100) of a wireless communication network assigns a selection probability to each of a plurality of frequency channels. On the basis of the selection probabilities, the access node (100) randomly selects one of the frequency channels as current operating frequency channel of the access node (100). Further, the access node (100) determines a channel quality of the current operating frequency channel. In response to the channel quality of the current operating frequency channel complying with a configured selection criterion, the access node (100) maintains the current operating frequency channel. In response to the channel quality of the current operating frequency channel not complying with the configured selection criterion, the access node selects, randomly on the basis of the selection probabilities, a further one of the frequency channels for evaluation and compares a channel quality of the frequency channel selected for evaluation to the channel quality of the current operating frequency channel. In response to the channel quality of the frequency channel selected for evaluation being higher than the channel quality of the current operating frequency channel, the access node (100) sets the frequency channel selected for evaluation as new operating frequency channel of the access node (100). In response to the channel quality of the frequency channel selected for evaluation not being higher than the channel quality of the current operating frequency channel, the access node (100) maintains the current operating frequency channel and decrementing the selection probability assigned to the frequency channel selected for evaluation.
