Techniques updating beams in periodic transmissions

A method for wireless communications at a base station, comprising:

• determining a first transmission on a first set of beams is unsuccessful;
• determining a second transmission on a second set of beams is successful;
• receiving, from a user equipment (UE), an indication of a beam from the second set of beams;
• and
• communicating with the UE via the indicated beam.

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 a first transmission on a first set of beams is unsuccessful;
• determine a second transmission on a second set of beams is successful;
• identify a beam from the second set of beams based at least in part on the determination that the second transmission on the second set of beams is successful;
• transmit, to a base station, an indication of the identified beam from the second set of beams;
• and
• communicate with the base station via the identified beam from the second set of beams.
