Examples of network nodes 200 are CBSDs, radio base stations, base transceiver stations, Node Bs, evolved Node Bs, gigabit Node Bs, access points, and access nodes. Examples of wireless devices 300a, 300b are mobile stations, mobile phones, handsets, wireless local loop phones, user equipment (UE), smartphones, laptop computers, tablet computers, network equipped sensors, network equipped vehicles, and so-called Internet of Things devices. In some aspects at least one of the wireless devices 300a, 300b is a wireless device with high UE category, for example category 6 or higher.

The embodiments disclosed herein relate to mechanisms for channel reconfiguration in a communications network 100. In order to obtain such mechanisms there is provided a network node 200, a method performed by the network node 200, a computer program product comprising code, for example in the form of a computer program, that when run on a network node 200, causes the network node 200 to perform the method.

The inventors of the enclosed embodiments have realized that in an operating communications network, the network node and wireless devices served by the network node have different interfering sources. The reliability of the channel selection might therefore be improved if considering received signal strength indicator (RSSI) measurements performed both by the served wireless devices and the network node. However, it is still unknown how to use RSSI measurements from wireless devices and how to combine them with RSSI measurements from the network node during channel selection.
