First radio access technology (RAT) channel state feedback (CSF) to increase accuracy of interference estimates from second RAT neighbor cells with dynamic spectrum sharing (DSS)

A method for wireless communication performed by a base station associated with a first radio access technology (RAT), comprising:

• configuring at least one reporting configuration and at least one resource configuration for a plurality of channel state information-interference measurement (CSI-IM) resource patterns associated with the first RAT, each CSI-IM resource pattern of the plurality of CSI-IM resource patterns corresponding to a time and frequency location in a resource block of a neighbor cell associated with a second RAT;
• transmitting, to a user equipment (UE), a message comprising the at least one reporting configuration and the at least one resource configuration;
• and
• receiving, from the UE, at least one CSI report based on the transmitted message.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus:
• to receive, from a base station, a message comprising at least one reporting configuration and at least one resource configuration for a plurality of channel state information-interference measurement (CSI-IM) resource patterns associated with a first radio access technology (RAT), each CSI-IM resource pattern of the plurality of CSI-IM resource patterns corresponding to a time and frequency location in a resource block of a neighbor cell associated with a second RAT;
• and
• to transmit at least one CSI report based on the at least one reporting configuration and the at least one resource configuration.
