Abstract

A method for using a code division multiple access (CDMA) subscriber unit to transmit a communication to a base station at a first data rate using at least one communication channel, determine an adjusted data rate desired for support of the communication, and transmit the communication to the base station over a second channel at a second data rate, wherein the first data rate is different than the second data rate.

Claims

1. A code division multiple access (CDMA) subscriber unit comprising:

an antenna;

a circuit coupled to the antenna configured to establish a connection with a base station;

the circuit being further configured to transmit a communication to the base station over a first channel at a first data rate and a second channel at a second data rate, wherein the first data rate is different than the second data rate;

the circuit being configured to receive power control information from the base station that is time division multiplexed onto a physical channel using control signaling; and

the circuit being further configured to adjust a power level associated with at least one of the channels in accordance with the power control information.

2. The CDMA subscriber unit of claim 1, wherein the circuit is further configured to determine an adjusted data rate desired for support of the communication.

3. The CDMA subscriber unit of claim 1, further comprising a digital signal processor.

4. The CDMA subscriber unit of claim 1, further comprising a CODEC circuit.

5. The CDMA subscriber unit of claim 1, wherein the circuit is further configured to receive two calls simultaneously.

6. A method for use in a code division multiple access (CDMA) subscriber unit, the method comprising:

establishing a connection with a base station;

transmitting a communication to a base station over the first channel at a first data rate and a second channel at a second data rate, wherein the first data rate is different than the second data rate;

receiving power control information from the base station that is time division multiplexed onto a physical channel using control signaling; and

adjusting a power level associated with at least one of the channels in accordance with the power control information.

7. The method of claim 6, further comprising determining an adjusted data rate desired for support of the communication.

8. The method of claim 6, further comprising receiving two calls simultaneously.

9. A code division multiple access (CDMA) communication system comprising:

a base station; and

a subscriber unit including;

an antenna; and

a circuit, coupled to the antenna, configured to establish a connection with the base station, transmit a communication to the base station over a first channel at a first data rate and a second channel at a second data rate, the first data rate being different than the second data rate, receive power control information from the base station that is time division multiplexed onto a physical channel using control signaling, and adjust a power level associated with at least one of the channels in accordance with the power control information.

10. The CDMA communication system of claim 9, wherein the circuit is further configured to determine an adjusted data rate desired for support of the communication.

11. The CDMA communication system of claim 9, wherein the circuit is further configured to receive two calls simultaneously.
