Abstract

A user equipment (UE) is configured to report channel state information (CSI) to a base station of a network. The UE receives configuration information from the base station including one or more interference measurement resources (IMRs) to be measured by the UE, determines a noise power for each of the IMRs, transmits a reference channel state information (CSI) report the base station, measures 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 transmits 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.
