1. A network node configured to communicate with a wireless device, the network node comprising:
processing circuitry configured to:
configure a first measurement resource for channel measurements;
configure a second measurement resource for interference measurements;
cause transmission of a first signal with a first predefined power level in a transmission occasion of the first measurement resource;
cause transmission of a second signal with a second predefined power level in a transmission occasion of the second measurement resource, at least one of the first predefined power level and the second predefined power level is configured to at least in part mitigate channel quality indication, CQI, saturations;
cause transmission of a third signal with a third predefined power level in another transmission occasion of the second measurement resource;
receive a first reported CQI associated with the second signal;
receive a second reported CQI associated with the third signal, the first reported CQI being different than the second reported CQI;
estimate a signal to interference plus noise ratio, SINR, based on at least one of the first reported CQI and second reported CQI; and
perform at least one action based at least in part on the estimated SINR.
