1. A method for wireless communications by a user equipment (UE), the method comprising:
receiving, from a network entity of a first radio access technology (RAT), signaling configuring the UE with multiple cell specific reference signal (CRS) rate matching patterns for a second RAT;
receiving, from the network entity, signaling configuring the UE to report measurements to allow the network entity of the first RAT to detect one or more strongest interfering neighbor cells for a reference channel state information (CSI) report configured with CSI interference measurement (CSI-IM) resources not overlapping with CRS resources of neighboring cells of the second RAT;
receiving, from the network entity, signaling to trigger at least one of the multiple CRS rate matching patterns; and
performing rate matching for one or more physical downlink shared channel (PDSCH) transmissions from the network entity of the first RAT based on the triggered at least one CRS rate matching pattern.
