USING A CONFIGURED NEGATIVE ACKNOWLEDGEMENT TRANSMISSION SCHEME FOR ERROR CAUSE INDICATION: abstract simplified (18000649)

Methods, systems, and devices for wireless communications are described in this abstract. The abstract explains a method for wireless communications at a user equipment (UE). The UE receives a configuration that indicates a feedback transmission scheme for reporting feedback associated with a specific type of error. The UE then detects an error in receiving a downlink transmission from a base station, where the detected error matches the specific type of error indicated in the configuration. Based on this detection and the configuration, the UE selects a feedback transmission scheme for transmitting a negative acknowledgement message for the downlink transmission. Finally, the UE transmits the negative acknowledgement message to the base station using the selected feedback transmission scheme.
