Abstract

A method and apparatus for selecting a favored transmission slot for communicating non-voice data in conjunction with a voice-data communication. The slot, reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel, is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The favored transmission slot is selected without the remote station messaging information to the base station concerning frequency channel or interference information for the supplemental channel.

Claims

1. An apparatus for transmitting data in a wireless communication system, the apparatus comprising:

means for transmitting signals containing voice-data from a base location via at least one first channel;

means for measuring at the base location transmission power levels for the voice-data transmitted via the at least one first channel;

means for determining a historical profile for the transmission power levels; and

means for using the historical profile for the transmission power levels to select a slot for transmitting additional data on a second channel.

2. The apparatus as in claim 1, wherein the first transmission channel is a fundamental channel.

3. The apparatus as in claim 2, wherein the second transmission channel is a supplemental channel.

4. The apparatus as in claim 2, wherein a first transmission on the fundamental channel is non-voice data.

5. The apparatus as in claim 2, wherein a first transmission on the fundamental channel is voice data and a second transmission on the supplemental channel is non-voice data.

6. The apparatus as in claim 5, wherein transmissions are spread-spectrum transmissions.

7. A method for transmitting data in a wireless communication system, the method comprising:

transmitting signals containing voice-data from a base location via at least one first channel;

measuring at the base location transmission power levels for the voice-data transmitted via the at least one first channel;

determining a historical profile for the transmission power levels; and

using the historical profile for the transmission power levels to select a slot for transmitting additional data on a second channel.

8. The method as in claim 7, wherein the first transmission channel is a fundamental channel.

9. The method as in claim 8, wherein the second transmission channel is a supplemental channel.

10. The method as in claim 8, wherein a first transmission on the fundamental channel is non-voice data.

11. The method as in claim 8, wherein a first transmission on the fundamental channel is voice data and a second transmission on the supplemental channel is non-voice data.

12. The method as in claim 11, wherein transmissions are spread-spectrum transmissions.

13. non-transitory processor readable media for storing instructions operable in a mobile wireless device to:

transmit signals containing voice-data from a base location via at least one first channel;

measure at the base location transmission power levels for the voice-data transmitted via the at least one first channel;

determine a historical profile for the transmission power levels; and

use the historical profile for the transmission power levels to select a slot for transmitting additional data on a second channel.

14. processor as in claim 13, wherein the first transmission channel is a fundamental channel.

15. The processor as in claim 14, wherein the second transmission channel is a supplemental channel.

16. The processor as in claim 14, wherein a first transmission on the fundamental channel is non-voice data.

17. The processor as in claim 14, wherein a first transmission on the fundamental channel is voice data and a second transmission on the supplemental channel is non-voice data.

18. The processor as in claim 17, wherein transmissions are spread-spectrum transmissions.

19. An apparatus for wireless communication, comprising:

at least one processor; and

a memory coupled to the at least one processor,

a receiver configured to receive two or more signals from two or more cells;

wherein the at least one processor is configured to;

transmit signals containing voice-data from a base location via at least one first channel;

measure at the base location transmission power levels for the voice-data transmitted via the at least one first channel;

determine a historical profile for the transmission power levels; and

use the historical profile for the transmission power levels to select a slot for transmitting additional data on a second channel.
