1. 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:
receive a configuration for reporting feedback associated with beam blocking;
perform a decoding process on one or more downlink transmissions received via a plurality of beams;
determine, in accordance with the configuration, whether a failure of the decoding process is a result of one or more of the plurality of beams being at least partially blocked during the one or more downlink transmissions based at least in part on comparing a value associated with the one or more downlink transmissions to a plurality of thresholds; and
transmit a negative acknowledgement and link adaptation information, wherein the negative acknowledgement is based at least in part on the failure of the decoding process and the link adaptation information is based at least in part on determining whether the one or more of the plurality of beams are at least partially blocked; and
wherein the value comprises at least one of:
an average receive power of a reference signal across a system bandwidth;
a receive power of a reference signal associated with a resource block;
an average receive power of a reference signal taken over a coherence time; or
a difference between a receive power of a reference signal associated with a first time and a receive power of a reference signal associated with a second time.
