Abstract: A shared spectrum is shared between at least a first RAT (radio access technology) and a second RAT. The channel measurements are for upcoming radio communications with a first User Equipment, UE, of the first RAT. The network node determines a required number of first RAT subframes for the upcoming radio communications in a next time period, and a required number of second RAT subframes for the upcoming radio communications in a next time period.

The number of first RAT subframes and the number of second RAT subframes are distributed such that there are sufficient first RAT subframes for the first UE to perform channel measurements for its upcoming radio communication.
