14. A method, comprising:
transmitting configuration information including one or more interference measurement resources (IMRs) allocated for measurement by a user equipment (UE);
receiving a reference CSI report from the UE;
receiving a new CSI report including interference and noise power fluctuation feedback from the UE, wherein the interference and noise power fluctuation feedback comprises parameters to model interference and noise power fluctuation, a gamma distribution is used to model the interference and noise power fluctuation, and the parameters include the average interference and noise power (γ) and a shape factor (m);
selecting a modulation and coding scheme (MCS) for the UE based on at least the interference and noise power fluctuation feedback and the reference CSI report;
normalizing γ based on at least the noise power of the IMR in the reference CSI report; and
quantizing m with a non-uniform range.
