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

In this abstract, the focus is on methods, systems, and devices for wireless communications. It describes a specific method for wireless communications at a user equipment (UE). The method involves receiving a configuration that indicates a feedback transmission scheme for reporting feedback related to a specific type of error. The UE then detects an error in receiving a downlink transmission from a base station, and this error is of the specific error type mentioned in the configuration. Based on this detected error 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.
