Abstract

A method and system for packet retransmission that includes transmitting or receiving, by a transceiver, a plurality of packets. Next, a determination is made for a memory allocation between a retransmission function and one or more of an interleaving and a deinterleaving function, wherein the memory allocation is based on at least one communication parameter. Then, an identification of at least one packet of the plurality of packets as a packet that should not be retransmitted is performed.

First claim

The invention claimed is:

1. A method of packet retransmission comprising:
transmitting or receiving, by a transceiver, a plurality of packets;
determining, by a processor, a memory allocation between a retransmission function and one or more of an interleaving and a deinterleaving function, wherein the memory allocation is based on at least one communication parameter; and
identifying, by the processor, at least one packet of the plurality of packets as a packet that should not be retransmitted.

2. A method, in a transceiver, comprising:
determining a memory allocation between a retransmission function and one or more of an interleaving and a deinterleaving function, wherein the memory allocation is based on at least one communication parameter;
transmitting or receiving a first message indicating the memory allocation;
changing the memory allocation based on changes in a communication channel; and
transmitting or receiving a second message indicating the changed memory allocation.

3. The method of claim 2 , wherein the communication parameter is a Signal to Noise Ratio (SNR), measured on at least one subcarrier.

4. The method of claim 2 , wherein the communication parameter is an error correction capability.

5. The method of claim 2 , wherein the communication parameter is a latency requirement.

6. The method of claim 2 , wherein the communication parameter is a data rate.

7. The method of claim 2 , wherein the changes in a communication channel comprises an increase in bit errors.

8. The method of claim 2 , further comprising storing a packet in the retransmission buffer and retransmitting the packet based on a received message.

9. A device comprising:
a transceiver operable to determine a memory allocation between a retransmission function and one or more of an interleaving and a deinterleaving function, wherein the memory allocation is based on at least one communication parameter;
a transmitter operable to transmit or a receiver operable to receive a first message indicating the memory allocation;
the transceiver further operable to change the memory allocation based on changes in a communication channel; and
the transmitter further operable to transmit or a receiver further operable to receive a second message indicating the changed memory allocation.

10. The device of claim 9 , wherein the communication parameter is a Signal to Noise Ratio, SNR, measured on at least one subcarrier.

11. The device of claim 9 , wherein the communication parameter is an error correction capability.

12. The device of claim 9 , wherein the communication parameter is a latency requirement.

13. The device of claim 9 , wherein the communication parameter is a data rate.

14. The device of claim 9 , wherein the changes in a communication channel comprises an increase in bit errors.

15. The device of claim 9 , wherein the transmitter is further operable to storing a packet in the retransmission buffer and retransmit the packet based on a message received by the receiver.

16. A transceiver comprising:
means for determining a memory allocation between a retransmission function and one or more of an interleaving and a deinterleaving function, wherein the memory allocation is based on at least one communication parameter;
means for transmitting or receiving a first message indicating the memory allocation;
means for changing the memory allocation based on changes in a communication channel; and
means for transmitting or receiving a second message indicating the changed memory allocation.

17. The transceiver of claim 16 , wherein the communication parameter is a Signal to Noise Ratio, SNR, measured on at least one subcarrier.

18. The transceiver of claim 16 , wherein the communication parameter is an error correction capability.

19. The transceiver of claim 16 , wherein the communication parameter is a latency requirement.

20. The transceiver of claim 16 , wherein the communication parameter is a data rate.

21. The transceiver of claim 16 , wherein the changes in a communication channel comprises an increase in bit errors.

22. The transceiver of claim 16 , further comprising means for storing a packet in the retransmission buffer and means for retransmitting the packet based on a received message.
