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.
Claims28
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.
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.
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.
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.
