1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a base station, first control signaling identifying a set of transmission mode indicators or transmission mode options and a set of corresponding demodulation reference signal configurations associated with each transmission mode of a set of transmission modes, the set of transmission modes to be addressed by a UE receiver to receive one or more data messages from multiple transmission reception points;
receiving, from the base station, second control signaling indicating a transmission mode of the set of transmission modes or a combination of transmission mode indicators and a combination of one or more demodulation reference signal configuration parameters to signal one or more demodulation reference signal configurations corresponding to the indicated transmission mode;
identifying, based at least in part on the transmission mode indicators and the one or more demodulation reference signal configuration parameters, at least one demodulation reference signal configuration of the set of demodulation reference signal configurations and the transmission mode of the set of transmission modes;
receiving one or more demodulation reference signals from the multiple transmission reception points according to the identified at least one demodulation reference signal configuration; and
receiving, from the multiple transmission reception points, the one or more data messages based at least in part on the indicated transmission mode and the received one or more demodulation reference signals.
