Abstract

Claims (17)

1. A method of managing storage of HARQ packets, comprising:

a wireless device receiving variable length HARQ packets;

the wireless device performing an error check on each received variable length HARQ packet; and

storing within HARQ memory the HARQ packets;

wherein storing each HARQ packet comprises;

dividing the HARQ packet into HARQ sub-packets;

storing each HARQ sub-packet;

recording storage locations and storage order of each of the HARQ sub-packets.

2. The method of claim 1 , further comprising the wireless device only storing HARQ packets within the HARQ memory that fail the error check.

3. The method of claim 1 , wherein the error check is performed on each received variable length HARQ packet after combining the received variable length HARQ packet with a previously received variable length HARQ packet having a same channel identification.

4. The method of claim 1 , further comprising accessing HARQ packets stored in the HARQ memory based on the storage locations and the storage order of the HARQ sub-packets.

5. The method of claim 4 , wherein accessing the HARQ packets stored in the HARQ memory further comprises appending corresponding HARQ sub-packets to form HARQ packets as originally stored.

6. The method of claim 1 , wherein the HARQ memory and receiver circuitry are located on a common integrated circuit.

7. The method of claim 1 , wherein the HARQ sub-packets each include a number of bits that corresponds with a predetermined block size of the HARQ memory.

8. The method of claim 1 , wherein the HARQ sub-packets are stored in non-continuous memory block locations of the HARQ memory.

9. The method of claim 1 , wherein the error check is a CRC error check of each of the HARQ packets.

10. The method of claim 1 , wherein the wireless device comprises a subscriber unit that supports a WiMax aggregation mode.
