Bundle size reporting for precoding resource block groups

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

• transmitting a first signal to a second wireless device;
• receiving, from the second wireless device, a feedback message indicating a first bundle size for a precoding resource block group associated with a second signal, the first bundle size based at least in part on a second bundle size associated with the first signal;
• and
• transmitting, to the second wireless device, the second signal based at least in part on the feedback message.

An apparatus for wireless communications at a first wireless 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:
• receive a first signal from a second wireless device;
• identify a first bundle size for a precoding resource block group based at least in part on a characteristic of the first signal;
• and
• transmit, to the second wireless device, a feedback message indicating a second bundle size for the precoding resource block group associated with a second signal based at least in part on identifying the first bundle size.
