Abstract
The described technology is generally directed towards indicating to a receiver (e.g., a user equipment) which antenna ports are assigned for channel state information reference signals (CSI-RS). The indicator can be sent as radio resource control configuration data and/or by physical layer signaling such as in downlink control information. The receiver computes CSI based on the assigned antenna port or ports, and the reported (e.g., joint) CSI helps avoid mismatched joint CSI used for scheduling when multiple transmit and receive points (TRPs) are communicating with the user equipment.
