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 from a mobile station in a wireless communication system, wherein each data packet received is transmitted in a number of installments, the method comprising:

transmitting a first negative acknowledgement message for a last installment of a first subpacket, the first negative acknowledgement transmitted at a first time slot; and

transmitting a second negative acknowledgement message for the last installment of the first subpacket, the second negative acknowledgement transmitted at a second time slot,

wherein the second time slot is designated for the first subpacket of the next packet,

wherein the first negative acknowledgement message has a first bit pattern, and the second negative acknowledgement message has a second bit pattern orthogonal to the first bit pattern.

2. The method as in claim 1, further comprising transmitting a third negative acknowledgement message for the first subpacket of the next packet, wherein the third negative acknowledgement message has a third bit pattern orthogonal to the second bit pattern.

3. The method as in claim 1, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a reduced power level relative to an acknowledgement message.

4. The method as in claim 1, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a same power level allocated to an acknowledgement message.

5. The method as in claim 1, wherein an acknowledgement message is transmitted at the first time slot with little or no power.

6. An apparatus for transmission from a mobile station in a wireless communication system, wherein each data packet received is transmitted in a number of installments, the apparatus comprising:

means for transmitting a first negative acknowledgement message for a last installment of a first subpacket, the first negative acknowledgement transmitted at a first time slot; and

means for transmitting a second negative acknowledgement message for the last installment of the first subpacket, the second negative acknowledgement transmitted at a second time slot,

wherein the second time slot is designated for the first subpacket of the next packet,

wherein the first negative acknowledgement message has a first bit pattern, and the second negative acknowledgement message has a second bit pattern orthogonal to the first bit pattern.

7. The apparatus as in claim 6, further comprising means for transmitting a third negative acknowledgement message for the first subpacket of the next packet, wherein the third negative acknowledgement message has a third bit pattern orthogonal to the second bit pattern.

8. The apparatus as in claim 6, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a reduced power level relative to an acknowledgement message.

9. The apparatus as in claim 6, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a same power level allocated to an acknowledgement message.

10. The apparatus as in claim 6, wherein an acknowledgement message is transmitted at the first time slot with little or no power.

11. A computer-program product for transmission from a mobile station in a wireless communication system, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:

code for transmitting a first negative acknowledgement message for a last installment of a first subpacket, the first negative acknowledgement transmitted a first time slot; and

code for transmitting a second negative acknowledgement message for the last installment of the first subpacket, the second negative acknowledgement transmitted at a second time slot,

wherein the second time slot is designated for the first subpacket of the next packet,

wherein the first negative acknowledgement message has a first bit pattern, and the second negative acknowledgement message has a second bit pattern orthogonal to the first bit pattern.

12. The computer-program product as in claim 11, the instructions further comprising code for transmitting a third negative acknowledgement message for the first subpacket of the next packet, wherein the third negative acknowledgement message has a third bit pattern orthogonal to the second bit pattern.

13. The computer-program product as in claim 11, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a reduced power level relative to an acknowledgement message.

14. The computer-program product as in claim 11, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a same power level allocated to an acknowledgement message.

15. The computer-program product as in claim 11, wherein an acknowledgement message is transmitted at the first time slot with little or no power.

16. An apparatus for transmission from a mobile station in a wireless communication system, wherein each data packet received is transmitted in a number of installments, the apparatus comprising:

a transmitter for transmitting a first negative acknowledgement message for a last installment of a first subpacket, the first negative acknowledgement transmitted at a first time slot, and

for transmitting a second negative acknowledgement message for the last installment of the first subpacket, the second negative acknowledgement transmitted at a second time slot,

wherein the second time slot is designated for the first subpacket of the next packet,

wherein the first negative acknowledgement message has a first bit pattern, and the second negative acknowledgement message has a second bit pattern orthogonal to the first bit pattern.

17. The apparatus as in claim 16, wherein the transmitter transmits a third negative acknowledgement message for the first subpacket of the next packet, wherein the third negative acknowledgement message has a third bit pattern orthogonal to the second bit pattern.

18. The apparatus as in claim 16, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a reduced power level relative to an acknowledgement message.

19. The apparatus as in claim 16, wherein the first negative acknowledgement message and the second negative acknowledgement message are transmitted at a same power level allocated to an acknowledgement message.

20. The apparatus as in claim 16, wherein an acknowledgement message is transmitted at the first time slot with little or no power.
