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.

First claim

What is claimed is:

1. A code division multiple access (CDMA) subscriber unit comprising:
an antenna;
a circuit coupled to the antenna, the circuit configured to transmit a communication to a base station over a first channel at a first data rate;
the circuit further configured to determine an adjusted data rate desired for support of the communication; and
the circuit further configured to 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;
wherein the circuit is further configured to receive power control information from the base station that is time 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.

2. The CDMA subscriber unit of claim 1 wherein the antenna is configured to receive the power control information which is time division multiplexed onto a physical channel with signaling information.

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:
transmitting a communication to a base station at a first data rate using at least one of communication channel;
determining an adjusted data rate desired for support of the communication;
transmitting 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; and
receiving power control information from the base station that is time 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 receiving the power control information which is time division multiplexed onto a physical channel with signaling information.

8. The method of claim 7 further comprising receiving two calls simultaneously.
