FLOW CONTROL FEEDBACK FOR FULL-DUPLEX COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communication are described. The described techniques provide for improving negative acknowledgment (NACK) feedback from a user equipment (UE) to limit self-interference during full-duplex communications with a base station. After failing to receive a downlink transmission from a base station, a UE may generate feedback associated with self-interference at the UE to transmit to the base station. The UE may then transmit a report to the base station indicating that the UE failed to successfully decode the downlink transmission, and the UE may include the feedback associated with self-interference at the UE in the report. The base station may receive the report and adapt configurations used for full-duplex communications with the UE based on the feedback to limit self-interference at the UE during full-duplex communications.
