1. An apparatus comprising:
one or more processors to:
obtain downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH) transmission with a plurality of repetitions, the DCI to indicate one or more transmission configuration indicator (TCI) states for reception of the PDSCH transmission;
receive, within a threshold time period from the DCI, a first set of downlink transmissions that includes at least one a first repetition of the plurality of repetitions using a first beam, a first modulation order, a first target code rate, a first transport block (TB) size, and a first downlink channel duration, wherein the first beam is a default beam;
switch from the first beam to a second beam, different from the first beam, based at least in part on the one or more TCI states;
receive, outside of the threshold time period from the DCI, a second set of downlink transmissions that includes at least one additional repetition of the plurality of repetitions using the second beam, a second modulation order, a second target code rate, a second TB size, and a second downlink channel duration, wherein the second target code rate is a multiple of the first target code rate and the second downlink channel duration is a fraction of the first downlink channel duration; and
a bus coupled with the one or more processors to communicatively couple the one or more processors to a component of a device.
