Numerous techniques exist for detecting and correcting errors that are introduced during the transmission of information (e.g., a data frame) between two pieces of network equipment, including, for example, forward error correction (FEC), cyclic redundancy check (CRC), hybrid automatic repeat request (HARQ), etc. Use of such techniques carries a cost, often shared between the transmitter and the receiver, comprising increased latency, consumption of bandwidth, the use of computational resources for verification and correction, etc. Techniques are presented herein that support a new method for detecting and correcting errors that leverages a return channel of a bidirectional radio environment to provide a feedback loop through which FEC may be focused just on the areas of a frame that are poorly received, thereby avoiding the latency, bandwidth, etc. costs that would be associated with retransmission of areas of the frame that are well received. The techniques presented herein build on new capabilities of full duplex radios and apply to, for example, Wi-Fi® 6 and 7 and Third Generation Partnership Project (3GPP) Fifth Generation (5G) networks.
