According to a first aspect there is presented a method for channel reconfiguration in a communications network. The method is performed by a network node. The method comprises obtaining RSSI measurements 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. The RSSI measurements trigger a need for the network node to perform channel reconfiguration. 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, thereby performing the channel reconfiguration.

According to a second aspect there is presented a network node for channel reconfiguration in a communications network. The network node comprises processing circuitry. The processing circuitry is configured to cause the network node to obtain RSSI measurements 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. The RSSI measurements trigger a need for the network node to perform channel reconfiguration. The processing circuitry is configured to cause the network node to select 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, thereby performing the channel reconfiguration.
