Reference signal phase time drift model reporting for reference signal time-domain coherency in new radio

A method for wireless communications at a receiving device, comprising:

• receiving, from a user equipment (UE), an indication of one or more sets of transmission parameters for a reference signal type, the indication associated with how a characteristic of one or more ports of the UE varies across time;
• bundling reference signals of the reference signal type that are transmitted by the UE based at least in part on the indication of the one or more sets of transmission parameters;
• and
• communicating with the UE based at least in part on the one or more sets of transmission parameters and bundling the reference signals of the reference signal type.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• determine one or more sets of transmission parameters associated with a reference signal type, the one or more sets of transmission parameters for enabling a receiving device to bundle reference signals of the reference signal type;
• transmit, to the receiving device, an indication of the one or more sets of transmission parameters, the indication associated with how a characteristic of one or more ports of the UE varies across time;
• and
• communicate with the receiving device based at least in part on the one or more sets of transmission parameters.
