Separate power control for the forward voice channel and forward data channel is provided without using additional bandwidth or decreasing the amount of pilot signal provided from the mobile to the base station. Alternating voice and data power control commands or information are transmitted in the pilot channel by a mobile to a base station. In one embodiment, the power control portion of a first pilot channel segment is used to provide power control for the forward voice channel and then in the following pilot channel segment, the power control portion is used to provide power control for the forward data channel. In other embodiments, other than a 50/50 mix between voice and data power control is provided in the mobile's pilot channel. For example, forward voice channel power control commands may be transmitted two or more times for each transmission of forward data channel power control commands.

1. A method for communicating power control information for at least two communication channels, comprising:transmitting power control information for a forward voice channel to be transmitted from a base station to a mobile station in a portion of a first segment of a reverse pilot channel transmitted from the mobile station to the base station; and transmitting power control information for a forward data channel in a corresponding portion of a second segment of the reverse pilot channel. 2. The method of claim 1, further comprising alternating between the transmission of power control information for the forward voice channel and the transmission of power control information for the forward data channel.3. The method of claim 1, further comprising transmitting power control information for a third forward channel within a corresponding portion of a third segment of the reverse pilot channel, the third segment being one of the plurality of repeating segments, wherein the third forward channel is one of a forward data channel, forward voice channel and forward video channel.4. The method of claim 1, wherein power control information for the first forward channel is transmitted at least two or mote times for each transmission of power control information for the second channel.5. The method of claim 1, wherein the first segment is one of a plurality of repeating segments and the second segment is one of the plurality of repeating segments.6. A method for communicating power control information for at least two communication channels, comprising:transmitting power control information in a portion of a first segment of a reverse pilot channel transmitted from a mobile station to a base station, wherein the power control information is for a first forward channel that is to be transmitted from the base station to the mobile station, the first segment being one of a plurality of repeating segments; and transmitting power control information in a corresponding portion of a second segment of the reverse pilot channel, wherein the power control information is for a second forward channel to be transmitted from the base station to the mobile station, the second segment being one of the plurality of repeating segments, wherein the first forward channel carries different information than the second forward channel. 7. The method of claim 6, wherein the power control information for the first forward channel is different than the power control information for the second forward channel.8. The method of claim 6, wherein the first forward channel is one of a voice channel, data channel and video channel.9. The method of claim 6, wherein the second forward channel is one of a voice channel, data channel and video channel.10. The method of claim 6, further comprising alternating between the transmission of power control information for the first forward channel and the transmission of power control information for the second forward channel.11. The method of claim 6, further comprising transmitting power control information in a corresponding portion of a third segment of the reverse pilot channel, wherein the power control information is for a third forward channel that is to be transmitted from the base station to the mobile station.12. The method of claim 11, whereinthe third segment is one of the plurality of repeating segments, and the third forward channel is one of a forward data channel, forward voice channel and forward video channel. 13. The method of claim 6, wherein power control information for the first forward channel is transmitted at least two or more times for each transmission of power control information for the second channel.14. A method for communicating power control information for at least two communication channels, comprising:transmitting power control information in a portion of a first segment of a reverse pilot channel transmitted from a mobile station to a base station, wherein the power control information is for a first forward channel to be transmitted from the base station to the mobile station, the first segment being one of a plurality of repeating segments; and transmitting power control information in a corresponding portion of a second segment of the reverse pilot channel, wherein the power control information is for a second forward channel to be transmitted from the base station to the mobile station, the second segment being one of the plurality of repeating segments. 15. The method of claim 14, wherein the power control information for the first forward channel is different than the power control information for the second forward channel.16. The method of claim 14, whereinthe first forward channel is one of a voice channel, data channel and video channel and the second forward channel is different from the first forward channel and is one of a voice channel data channel and video channel. 17. The method of claim 14, further comprising alternating between the transmission of power control information for the first forward channel and the transmission of power control information for the second forward channel.18. The method of 14, further comprising transmitting power control information in a corresponding portion of a third segment of the reverse pilot channel, wherein the power control information is for a third forward channel that is to be transmitted from the base station to the mobile station.19. The method of claim 18, whereinthe third segment is one of the plurality of repeating segments, and the third forward channel is one of a forward data channel, forward voice channel and forward video channel. 20. The method of claim 14, wherein power control information for the first forward channel is transmitted at least two or more times for each transmission of power control information for the second channel.
