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.

First claim

The invention claimed is:

1. An apparatus comprising:
a multicarrier transceiver including a processor and memory capable of:
transmitting a packet using forward error correction encoding and interleaving, 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
receiving a message using forward error correction decoding and without using deinterleaving, wherein the message is received in a single DMT symbol, and wherein the message includes an acknowledgement (ACK) or a negative acknowledgement (NACK) of the transmitted packet.

2. The apparatus of claim 1 , wherein the received message has a higher immunity to noise than the transmitted packet.

3. The apparatus of claim 1 , wherein the transceiver is capable of retransmitting the packet using forward error correction encoding and interleaving.

4. The apparatus of claim 1 , wherein a physical layer of the transceiver is capable of generating the packet and the message.

5. The apparatus of claim 1 , wherein a layer above a physical layer of the transceiver is capable of generating the packet and the message.

6. The apparatus of claim 2 , wherein a physical layer of the transceiver is capable of generating the packet and the message.

7. The apparatus of claim 2 , a layer above a physical layer of the transceiver is capable of generating the packet and the message.

8. An apparatus comprising:
a multicarrier transceiver including a processor and memory capable of:
receiving a packet using forward error correction decoding and deinterleaving, 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
transmitting a message using forward error correction encoding and without using interleaving, wherein the message is transmitted in a single DMT symbol and wherein the message includes an acknowledgement (ACK) or a negative acknowledgement (NACK) of the received packet.

9. The apparatus of claim 8 , wherein the transmitted message has a higher immunity to noise than the received packet.

10. The apparatus of claim 8 , wherein the transceiver is capable of receiving a retransmitted packet using forward error correction decoding and deinterleaving.

11. The apparatus of claim 8 , wherein a physical layer of the transceiver is capable of generating the packet and the message.

12. The apparatus of claim 8 , wherein a layer above a physical layer of the transceiver is capable of generating the packet and the message.

13. The apparatus of claim 9 , wherein a physical layer of the transceiver is capable of generating the packet and the message.

14. The apparatus of claim 9 , wherein a layer above a physical layer of the transceiver is capable of generating the packet and the message.

15. A non-transitory computer-readable information storage media having stored thereon instructions, that when executed by one or more processors in a transceiver, cause the transceiver to:
transmit a packet using forward error correction encoding and interleaving, 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
receive a message using forward error correction decoding and without using deinterleaving, wherein the message is received in a single DMT symbol, and wherein the message includes an acknowledgement (ACK) or a negative acknowledgement (NACK) of the transmitted packet.

16. The media of claim 15 , wherein the received message has a higher immunity to noise than the transmitted packet.

17. The media of claim 15 , wherein instructions further cause the transceiver to retransmit the packet using forward error correction encoding and interleaving.

18. The media of claim 15 , wherein instructions further cause a physical layer of the transceiver to generate the packet and the message.

19. The media of claim 15 , wherein instructions further cause a layer above a physical layer of the transceiver to generate the packet and the message.

20. The media of claim 16 , wherein instructions further cause a physical layer of the transceiver to generate the packet and the message.

21. The media of claim 16 , wherein instructions further cause a layer above a physical layer of the transceiver to generate the packet and the message.

22. A non-transitory computer-readable information storage media having stored thereon instructions, that when executed by one or more processors in a transceiver, cause the transceiver to:
receive a packet using forward error correction decoding and deinterleaving, 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
transmit a message using forward error correction encoding and without using interleaving, wherein the message is transmitted in a single DMT symbol and wherein the message includes an acknowledgement (ACK) or a negative acknowledgement (NACK) of the received packet.

23. The media of claim 22 , wherein the transmitted message has a higher immunity to noise than the received packet.

24. The media of claim 22 , wherein the instructions further cause the transceiver to retransmit the packet using forward error correction decoding and deinterleaving.

25. The media of claim 22 , wherein instructions further cause a physical layer of the transceiver to generate the packet and the message.

26. The media of claim 22 , wherein instructions further cause a layer above a physical layer of the transceiver to generate the packet and the message.

27. The media of claim 23 , wherein instructions further cause a physical layer of the transceiver to generate the packet and the message.

28. The media of claim 23 , wherein instructions further cause a layer above a physical layer of the transceiver to generate the packet and the message.
