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.

1-105. (canceled)
An apparatus comprising:
- a multicarrier transceiver including a processor and memory operable to:
- transmit a packet using a forward error correction encoder and an interleaver, 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 a forward error correction decoder and without using a deinterleaver, 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.
An apparatus comprising:
- a multicarrier transceiver including a processor and memory operable to:
- receive a packet using a forward error correction decoder and a deinterleaver, 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 a forward error correction encoder and without using an interleaver, 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.
A method, in a multicarrier transceiver, comprising:

- and
- receiving a message using a forward error correction decoder and without using a deinterleaver, 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.
