Abstract

A system and method of implementing a radio link protocol completion oriented packet data communication system. A data backlog is described with a media access control layer controller and transmitting a BEGIN protocol data unit containing a flag transmitted to a receiver. A media access control layer transaction is initiated in response to the transmitting of the BEGIN protocol data unit.

6. The method of claim 1, further including the step of terminating the media access control layer transaction when the transaction size field has a value equal to zero.

7. The method of claim 1, further including the step of transmitting the END control block by the media access control layer controller when the number of data blocks in a transmit buffer is less than the value of the system broadcast parameter.

8. The method of claim 7 further including the step of providing a last valid sequence number for the media access control layer transaction within the END control block.

9. The method of claim 8 further including the step of recovering all of a plurality of data sequence numbers up to and including the last valid sequence number.

2 indicate that the media access control layer transaction has a number of data blocks equal to the value of the transaction size field value.

11. The system of claim 10 further including a transmission controller for determining whether the media access control layer transaction is bounded from the flag.

12. The system of claim 11 further including an explicit END control block which is transmitted by the media access control layer controller when the number of data blocks in a transmit buffer is less than the value of the system broadest parameter.

13. The system of claim 12 further including a last valid sequence number for the media access control layer transaction within the END control block.

14. The system of claim 12 further including a receiver for recovering all of a plurality of data sequence numbers up to and including the last valid sequence number.

15. The system of claim 11 wherein the media access control layer transaction is composed of a number of a number of data blocks, and the media access control layer transaction has a beginning and an end.

16. The system of claim 15 wherein the data blocks are included in a CONTINUE protocol data unit.

17. The system of claim 16 wherein the BEGIN protocol data unit contains a transaction size field that defines the number of data blocks.

18. The system of claim 11 wherein the media access control layer transaction is composed of a number of a number of data blocks, and the media access control layer transaction has a beginning and an end.

19. The system of claim 18 wherein the data blocks are included in a CONTINUE protocol data unit.

20. The system of claim 19 wherein the data blocks are new data blocks.

21. The system of claim 19 wherein the data blocks are retransmitted data blocks.

22. The system of claim 18 wherein the transmission controller commits to the end of the media access control layer transaction.
