Channel state information reference signal resource mapping

Abstract

Various aspects of the present disclosure relate to channel state information reference signal (CSI-RS) resource mapping. A UE receives a configuration message for CSI-RS resource settings that indicates one or more CSI-RS resources. At least one of the one or more CSI-RS resources includes multiple active CSI-RS parts and is associated with subband full-duplex (SBFD) symbols and downlink (DL) symbols, where SBFD symbols include both uplink (UL) and DL frequency subbands, and DL symbols include only DL frequency subband. The UE transmits, based at least in part on the configuration message, one or more channel state information (CSI) reports indicating a first set of CSI report quantities computed based on a first CSI-RS frequency resource derived during a SBFD symbol from active CSI-RS parts and a second set of CSI report quantities computed based on a second CSI-RS frequency resource derived during a DL symbol from active CSI-RS parts.
