A power control system for use in facilitating transition to an active state suitable for use in a wireless communication system. In one aspect, the system includes a first transceiver, such as a BTS, having the ability to initiate transmission of a power control function. The transceiver comprises a generator for generating a power control arrangement and a transmitter for transmitting the power control arrangement. The system further includes a second transceiver, such as a terminal, for receiving the power control arrangement and coherently combining the power control arrangement to determine a state transition indication. The second transceiver includes a transmitter that transmits a selected waveform subsequent to the coherent combining. The first transceiver receives the selected waveform, determines a power level associated therewith, and provides feedback to the second transceiver. The power control arrangement may include groups of redundant power control data, data transmitted on idle feedback dimensions, or predetermined signal patterns in addition to at least one power control group.

1. A method for controlling signal strength transmitted in a wireless communication system, comprising:detecting at a second transceiver presence of a plurality of predetermined power control groups received from a first transceiver, wherein said first receiver ignores any power transmission level adjustment factor received; coherently combining the plurality of predetermined power control groups; determining whether the coherently combined power control groups constitute an indication to transition states; activating a transmitter at said second transceiver; and transmitting either: pre-determined waveforms, or regular traffic information, or said pre-determined waveforms followed by said regular traffic information. 2. The method of claim 1, further comprising:receiving the pre-determined waveforms or regular traffic information or said pre-determined waveforms followed by said regular traffic information at said second transceiver; and computing a power transmission level adjustment factor for the first receiver. 3. The method of claim 2, further comprising:transmitting said power transmission level adjustment factor to the first receiver; and adjusting a power level transmission at the first transceiver based on the power transmission level adjustment factor. 4. The method of claim 1, wherein said window of commands comprises feedback provided across an unused feedback dimension.5. The method of claim 4, wherein said unused feedback dimension comprises one from a group comprising:a transmission channel; a time slot; and a predetermined frequency. 6. The method of claim 1, wherein the window of commands comprises a predetermined transmission sequence.7. The method of claim 6, wherein the predetermined transmission sequence comprises elements unrelated to power control.8. The method of claim 2, further comprising:initiating a sequence subsequent to said detecting. 9. A method of transitioning states in a wireless communication system, comprising:receiving a plurality of predetermined power control groups at a first transceiver, wherein said first transceiver ignores any power transmission level adjustment factor received; coherently combining said predetermined power control groups at said first transceiver; determining whether the coherently combined power control groups constitute an indication to transition states; and transmitting, subsequent to said coherent combining, a transmission set from said first transceiver to a second transceiver, said transmission set comprising at least one from a group comprising: predetermined waveforms; and regular traffic. 10. The method of claim 9, further comprising:receiving the transmission set at the second transceiver; and computing a power transmission level adjustment factor for the first transceiver. 11. The method of claim 10, further comprising:transmitting said power transmission level adjustment factor to the first transceiver; and adjusting a power level transmission at the first transceiver based on the power transmission level adjustment factor. 12. The method of claim 9, wherein said power control information comprises feedback provided across an unused feedback dimension.13. The method of claim 12, wherein said unused feedback dimension comprises one from a group comprising:an unused transmission channel; an unused time slot; and an unused predetermined frequency. 14. The method of claim 9, wherein the power control information comprises a predetermined transmission sequence.15. The method of claim 14, wherein the predetermined transmission sequence comprises elements unrelated to power control.16. The method of claim 10, further comprising:initiating a sequence subsequent to said detecting.
