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 method for use in a subscriber unit for supporting a plurality of communication rates with a base station, the method comprising:

establishing an initial communication link with a base station;

at time intervals, determining a data rate required to support a first communication by the subscriber unit;

allocating by the subscriber unit, responsive to the determining step, a sufficient number of communication channels for transmission at said data rate whereby;

a re-allocation of communication channels is performed should the required data rate change, wherein at least one of the communication channels carries time multiplexed signaling information and power control information; and

adjusting a power level associated with at least one communication channel in accordance with the power control information.

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

an antenna; and

a circuit coupled to the antenna, the circuit being configured to establish an initial communication link with a base station, the circuit being configured to determine a data rate required to support a first communication at time intervals, wherein, in response to determining the data rate required to support the first communication, a sufficient number of communication channels for transmission at the data rate are allocated;

the circuit being further configured to reallocate the communication channels should the required data rate change, wherein at least one of the communication channels carries time multiplexed signaling information and power control information;

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