1. A method for wireless communication at a wireless device, comprising:
receiving control signaling indicating a periodicity associated with a plurality of feedback opportunities;
monitoring a set of time resources for a plurality of code blocks;
receiving, from a network entity and based at least in part on monitoring for the plurality of code blocks, a code block of the plurality of code blocks via an optical beam;
modulating the optical beam based at least in part on receiving the code block;
sending, to the network entity, the modulated optical beam during a feedback opportunity of the plurality of feedback opportunities in accordance with the periodicity, the modulated optical beam comprising feedback that indicates at least one code block of the plurality of code blocks was unsuccessfully received or decoded at the wireless device; and
receiving a retransmission of the at least one code block based at least in part on sending the modulated optical beam comprising the feedback.
