Abstract

A method for using a wireless digital base station to receive, process and transmit a plurality of communications having independent data rates establishing a first communication channel having a first data communication rate to support a first communication; determining the data rate required to support the first communication; selecting one or more transmission channels, from a plurality of available transmission channels, required to support said required data rate; and transmitting the first communication using one or more selected transmission channels. The plurality of available transmission channels includes at least one B or D channel.

Claims

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

an antenna; and

a circuit coupled to the antenna, the circuit being configured to provide a first signal to the antenna which is communicated to a base station over a first channel at a first data rate, the circuit being configured to generate a second signal which is communicated to the base station, wherein, in response to the second signal, a second channel is established between the CDMA subscriber unit and the base station, the circuit being configured to provide a third signal to the antenna which is communicated to the base station over the second channel at a second data rate different than the first data rate, wherein the circuit is further configured to receive two calls simultaneously;

wherein the antenna is configured to receive power control information which is time division multiplexed onto a physical channel with signaling information, the circuit being configured to adjust a power level associated with at least one of the first and second channels in accordance with the power control information.

2. The CDMA subscriber unit of claim 1, further including a digital signal processor.

3. The CDMA subscriber unit of claim 1, further including a CODEC circuit.

4. The CDMA subscriber unit of claim 2, further including a filter circuit.

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

transmitting a first signal to a base station over a first channel at a first data rate;

generating a second signal, wherein, in response to the second signal, a second channel is established between the CDMA subscriber unit and the base station;

transmitting a third signal to the base station over the second channel at a second data rate different than the first data rate;

receiving two calls simultaneously and power control information which is time division multiplexed onto a physical channel with signaling information; and

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