Beam preference feedback for data transmissions

An apparatus for wireless communications at a network device, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit one or more reference signals;
• receive an indication of multiple beam preferences for communicating with the network device based at least in part on the one or more reference signals, wherein the indication comprises a plurality of transmission configuration indication states, a plurality of spatial relations, or both, wherein the plurality of transmission configuration indication states, the plurality of spatial relations, or both indicate a set of one or more preferred beams and a set of one or more non-preferred beams;
• transmit, based at least in part on the indication of the multiple beam preferences, downlink control information indicating a beam for a data transmission;
• and
• communicate the data transmission using the indicated beam.

A method for wireless communications at a user equipment (UE), comprising:

• performing a measurement of one or more reference signals from a network device;
• transmitting, to the network device, an indication of multiple beam preferences for communicating with the network device based at least in part on the measurement of the one or more reference signals, wherein the indication comprises a plurality of transmission configuration indication states, a plurality of spatial relations, or both, wherein the plurality of transmission configuration indication states, the plurality of spatial relations, or both indicate a set of one or more preferred beams and a set of one or more non-preferred beams;
• receiving, based at least in part on the indication of the multiple beam preferences, downlink control information from the network device, the downlink control information indicating a beam for a data transmission;
• and
• communicating the data transmission using the indicated beam.
