FRA Flexible Radio Assignment - COF evaluation and temporarily interference

[steiostb1]

We are going to try out FRA in our network, but are not convinced how the COF is calculated. I have been reading the documentation, but cannot find out detailed info on how the COF is calculated. How long is the sensing periode? What about temporarily interference? Once the FRA have switched radio to 5G, it will not switch back to 2.4G (you have to do it manually).
