Abstract

Through the identification of different packet-types, packets can be handled based on an assigned packet handling identifier. This identifier can, for example, enable forwarding of latency-sensitive packets without delay and allow error-sensitive packets to be stored for possible retransmission. In another embodiment, and optionally in conjunction with retransmission protocols including a packet handling identifier, a memory used for retransmission of packets can be shared with other transceiver functionality such as, coding, decoding, interleaving, deinterleaving, error correction, and the like.

receives a packet using forward error correction decoding and, deinterleaves the packet using the allocated deinterleaver function memory, wherein the packet comprises a header field and a plurality of Reed-Solomon codewords, and wherein the header field comprises a sequence identifier (SID); and

transmits a second message using forward error correction encoding and without using interleaving, wherein the second message is received in a single DMT symbol, and wherein the second message includes an acknowledgement (ACK) or a negative acknowledgement (NACK) of the received packet.

15. The apparatus of claim 14 , wherein the second message has a higher SNR margin than the packet.

16. The apparatus of claim 14 , wherein a physical layer of the multicarrier transceiver generates the second message.

17. The apparatus of claim 14 , wherein a physical layer of the multicarrier transceiver generates the packet.

18. The apparatus of claim 15 , wherein a physical layer of the multicarrier transceiver generates the second message.

19. The apparatus of claim 15 , wherein a physical layer of the multicarrier transceiver generates the packet.
