摘要

Mechanisms are provided for channel reconfiguration in a communications network where shared spectrum from a primary incumbent is used. A method is performed by a network node, which comprises obtaining RSSI measurements on the current channel from wireless devices. The wireless devices are served by the network node at a current channel in a current frequency interval within a frequency band. When the RSSI measurements trigger a need for the network node to perform channel reconfiguration, the network node selects a new channel based on RSSI measurements that it itself performs. The method comprises selecting a new channel in a new or the same frequency interval, in a new or the same frequency band, for serving the wireless devices based on RSSI measurements performed by the network node, and channel reconfiguration for the wireless devices is performed.
