1. An apparatus for wireless communications, 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, from a base station, a feedback error configuration indicating at least one error threshold associated with at least one feedback error type of a plurality of feedback error types and at least one time window for feedback error detection per frequency band combination;
detect one or more feedback errors for the at least one feedback error type within the at least one time window; and
transmit, to the base station, a feedback error indication based at least in part on a number of the one or more feedback errors exceeding the at least one error threshold, wherein the feedback error indication comprises an indication of the one or more feedback errors and the at least one feedback error type associated with the one or more feedback errors.
 
15. An apparatus for wireless communications, comprising:
a processor,
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
transmit, to a user equipment (UE), a feedback error configuration indicating at least one error threshold associated with a feedback error type of a plurality of feedback error types and at least one time window for feedback error detection at the UE;
transmit a data message to the UE; and
receive, from the UE, a feedback error indication indicating one or more feedback errors detected by the UE and the feedback error type associated with the one or more feedback errors.
 
27. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a base station, a feedback error configuration indicating at least one error threshold associated with at least one feedback error type of a plurality of feedback error types, and at least one time window for feedback error detection per frequency band combination;
detecting one or more feedback errors for the at least one feedback error type within the at least one time window; and
transmitting, to the base station, a feedback error indication based at least in part on a number of the one or more feedback errors exceeding the at least one error threshold, wherein the feedback error indication comprises an indication of the one or more feedback errors and the at least one feedback error type associated with the one or more feedback errors.
 
29. A method for wireless communications at a base station, comprising:
transmitting, to a user equipment (UE), a feedback error configuration indicating at least one error threshold associated with a feedback error type of a plurality of feedback error types and at least one time window for feedback error detection at the UE per frequency band combination;
transmitting a data message to the UE;
and receiving, from the UE, a feedback error indication indicating one or more feedback errors detected by the UE and the feedback error type associated with the one or more feedback errors.
