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)

Abstract:

A user equipment (UE) receives, from a base station, a message including at least one reporting configuration and resource configuration for a number of channel state information-interference measurement (CSI-IM) resource patterns associated with a first radio access technology (RAT). Each of the configured CSI-IM resource patterns corresponds to a time and frequency location in a resource block of a neighbor cell associated with a second RAT. The UE transmits one or more CSI reports based on the reporting configuration(s) and the resource configuration(s).
