CHANNEL STATE INFORMATION REFERENCE SIGNAL (CSI-RS) AS PART OF DISCOVERY REFERENCE SIGNAL (DRS) CONFIGURATION AND INDICATION FOR NEW RADIO-UNLICENSED (NR-U)

Abstract:

Systems, methods, and circuitries are provided for configuring and indicating channel state information resource signals (CSI-RS) using discovery reference signal (DRS) resources. An example method includes determining discovery reference signal (DRS) resources for use in carrying channel state information reference signals (CSI-RS); generating CSI-RS configuration information that defines at least one CSI-RS using the DRS resources; and signaling the CSI-RS configuration information to a user equipment (UE) device.
