Abstract

Method and apparatus for power boosting a portion of installments in transmission of a packet of data. The power boosting incorporates a power boost factor for each installment. On receipt of a negative acknowledgement after the power boosted portion of installments, transmission of the subpacket is terminated, and processing passed to a higher layer.

Claims

1. A method for transmission of packetized data in a wireless communication system having a designated packet error rate, the method comprising:

determining at a transceiver a first number of installments for transmission of a first subpacket of data;

determining a second number of installments for transmission of the first subpacket of data, the second number less than the first number;

determining power boost gain factors for the second number of installments using latency tolerance information, the power boost gain factors satisfying the designated packet error rate;

power boosting transmissions of the second number of installments of the first subpacket of data by applying the power boost gain factors; and

terminating transmission of the first subpacket of data after the second number of installments.

2. The method as in claim 1, wherein the power boosting gain factors are nominally set to (N/M), wherein N is the first number of installments, and M is the second number of installments.

3. The method as in claim 1, wherein terminating transmission of the first subpacket of data comprises:

initiating a second subpacket of data after the second number of installments.

4. The method as in claim 1, wherein the first number of installments for the first subpacket of data corresponds to a first time period, wherein terminating transmission of the first subpacket of data comprises:

waiting for expiration of the first time period; and

initiating transmission of a second subpacket of data after expiration of the first time period.

5. The method as in claim 1, further comprising:

receiving a negative acknowledgement message after transmission of the second number of installments; and

processing the first subpacket of data at a higher layer.

6. The method as in claim 1, further comprising:

receiving an acknowledgement message before transmission of all of the second number of installments; and

initiating transmission of a second subpacket of data.

7. An apparatus for transmission of packetized data in a wireless communication system having a designated packet error rate, the apparatus comprising:

means for determining a first number of installments for transmission of a first subpacket of data;

means for determining a second number of installments for transmission of the first subpacket of data, the second number less than the first number;

means for determining power boost gain factors for the second number of installments using latency tolerance information, the power boost gain factors satisfying the designated packet error rate;

means for power boosting transmissions of the second number of installments of the first subpacket of data by applying the power boost gain factors; and

means for terminating transmission of the first subpacket of data after the second number of installments.

8. The apparatus as in claim 7, wherein the power boosting gain factors are nominally set to (N/M), wherein N is the first number of installments, and M is the second number of installments.

9. The apparatus as in claim 7, wherein means for terminating transmission of the first subpacket of data comprises:

means for initiating a second subpacket of data after the second number of installments.

10. The apparatus as in claim 7, wherein the first number of installments for the first subpacket of data corresponds to a first time period, wherein means for terminating transmission of the first subpacket of data comprises:

means for waiting for expiration of the first time period; and

means for initiating transmission of a second subpacket of data after expiration of the first time period.

11. The apparatus as in claim 7, further comprising:

means for receiving a negative acknowledgement message after transmission of the second number of installments; and

means for processing the first subpacket of data at a higher layer.

12. The apparatus as in claim 7, further comprising:

means for receiving an acknowledgement message before transmission of all of the second number of installments; and

means for initiating transmission of a second subpacket of data.

13. A computer-program product for transmitting packetized data in a wireless communication system having a designated packet error rate, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:

code for determining a first number of installments for transmission of a first subpacket of data;

code for determining a second number of installments for transmission of the first subpacket of data, the second number less than the first number;

code for determining power boost gain factors for the second number of installments using latency tolerance information, the power boost gain factors satisfying the designated packet error rate;

code for power boosting transmissions of the second number of installments of the first subpacket of data by applying the power boost gain factors; and

code for terminating transmission of the first subpacket of data after the second number of installments.

14. The computer-program product as in claim 13, wherein the power boosting gain factors are nominally set to (N/M), wherein N is the first number of installments, and M is the second number of installments.

15. The computer-program product as in claim 13, wherein the code for terminating transmission of the first subpacket of data comprises:

code for initiating a second subpacket of data after the second number of installments.

16. The computer-program product as in claim 13, wherein the first number of installments for the first subpacket of data corresponds to a first time period, wherein the code for terminating transmission of the first subpacket of data comprises:

code for waiting for expiration of the first time period; and

code for initiating transmission of a second subpacket of data after expiration of the first time period.

17. An apparatus for transmission of packetized data in a wireless communication system having a designated packet error rate, the apparatus comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable to;

determine a first number of installments for transmission of a first subpacket of data;

determine a second number of installments for transmission of the first subpacket of data, the second number less than the first number;

determine power boost gain factors for the second number of installments using latency tolerance information, the power boost gain factors satisfying the designated packet error rate;

power boost transmissions of the second number of installments of the first subpacket of data by applying the power boost gain factors; and

terminate transmission of the first subpacket of data after the second number of installments.

18. The apparatus as in claim 17, wherein the power boosting gain factors are nominally set to (N/M), wherein N is the first number of installments, and M is the second number of installments.

19. The apparatus as in claim 17, wherein terminating transmission of the first subpacket of data comprises:

initiating a second subpacket of data after the second number of installments.

20. The apparatus as in claim 17, wherein the first number of installments for the first subpacket of data corresponds to a first time period, wherein terminating transmission of the first subpacket of data comprises:

waiting for expiration of the first time period; and

initiating transmission of a second subpacket of data after expiration of the first time period.
