Outer-loop feedback support for low error rates

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, from a base station, a proxy acknowledgement feedback configuration for communications associated with a target error rate that is below a threshold target error rate;
• receive, from the base station, the communications associated with the target error rate;
• transmit, to the base station, a first acknowledgement feedback for the communications based at least in part on the target error rate and on decoding the communications;
• and
• transmit, to the base station, a second acknowledgement feedback for the communications based at least in part on the proxy acknowledgement feedback configuration, wherein the second acknowledgement feedback is associated with a proxy target error rate that is greater than the target error rate.

An apparatus for wireless communications at a user equipment (UE), comprising:

• means for receiving, from a base station, a proxy acknowledgement feedback configuration for communications associated with a target error rate that is below a threshold target error rate;
• means for receiving, from the base station, the communications associated with the target error rate;
• means for transmitting, to the base station, a first acknowledgement feedback for the communications based at least in part on the target error rate and on decoding the communications;
• and
• means for transmitting, to the base station, a second acknowledgement feedback for the communications based at least in part on the proxy acknowledgement feedback configuration, wherein the second acknowledgement feedback is associated with a proxy target error rate that is greater than the target error rate.

A non-transitory computer-readable medium storing code for wireless communications at a user equipment (UE), the code comprising instructions executable by a processor to:

• receive, from a base station, a proxy acknowledgement feedback configuration for communications associated with a target error rate that is below a threshold target error rate;
• receive, from the base station, the communications associated with the target error rate;
• transmit, to the base station, a first acknowledgement feedback for the communications based at least in part on the target error rate and on decoding the communications;
• and
• transmit, to the base station, a second acknowledgement feedback for the communications based at least in part on the proxy acknowledgement feedback configuration, wherein the second acknowledgement feedback is associated with a proxy target error rate that is greater than the target error rate.
