1. A user equipment (UE), comprising:
a transceiver configured to communicate with a base station; and
a processor communicatively coupled to the transceiver and configured to perform operations comprising:
receiving configuration information from the base station including one or more interference measurement resources (IMRs) to be measured by the UE;
determining a noise power for each of the IMRs;
transmitting a reference channel state information (CSI) report the base station;
measuring CSI reference signals (CSI RS) transmitted by the base station to determine an interference and noise power for each of the one or more IMRs; and
transmitting a new CSI report including one of i) only interference and noise power fluctuation feedback or ii) multiple signal-to-interference-plus-noise ratio (SINR) or SINR statistics to the base station,
wherein, when the one or more IMRs is less than or equal to a predetermined number of IMRs, the new CSI report includes a measured interference and noise power for each IMR.
