1. A method of wireless communication, comprising:
receiving, by a user equipment (UE) device, a joint transmission of channel state information (CSI) reference signals (CSI-RS) from a first transmission and reception point (TRP) associated with a wireless network and at least a second TRP associated with the wireless network;
determining a joint rank parameter associated with the joint transmission;
based on the joint rank parameter, accessing, by the UE device, a rank-to-port mapping codebook to determine a port index parameter; and
after determining the port index parameter, communicating, by the UE device, with one or more of the first TRP or the second TRP.
