According to a third aspect there is presented a network node for channel reconfiguration in a communications network. The network node comprises processing circuitry and a storage medium. The storage medium stores instructions that, when executed by the processing circuitry, cause the network node to perform operations, or steps. The operations, or steps, 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 operations, or steps, 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.

The network node comprises an obtain module configured 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 network node comprises a select module configured 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.
