Zusammenfassung:Methods and devices for reducing the latency associated with retransmitting data packets are provided. A device used to receive data packets may include physical layer circuitry and data link layer circuitry communicatively coupled to the physical layer circuitry. The data link layer circuitry may include an Automatic Repeat reQuest (ARQ) processing circuit to send requests for retransmitting data packets. The data link layer circuitry may also include a Forward Error Correction (FEC) processing circuit to receive decoded data packets from the physical layer circuitry, to perform error correction on packets received by the physical layer circuitry, and to provide a correction status signal to the ARQ processing circuit indicating whether or not a particular decoded data packet received from the physical layer circuitry contains one or more incurable errors.
