A CDMA communication system is provided in which bit rates are dynamically allocated by a single CDMA receiving station to a plurality of CDMA transmitting stations, all of which are intercoupled to each other over a CDMA channel and a feedback channel. Each CDMA transmitting station includes a control circuit which sends control signals on the CDMA channel in spaced apart time intervals which request respective bit rates on the CDMA channel; and, the CDMA receiving station includes a bit rate allocating circuit which receives and responds to the control signals by sending feedback messages over the feedback channel that address individual CDMA transmitting stations and grant respective bit rates to the addressed station. In one preferred embodiment, each transmitting station includes a data buffer which stores a time varying number of data bytes that are to be sent, and each transmitting station requests respective bit rates on the CDMA channel by including that number in the control signals.

A CDMA communication system, in which bit rates are dynamically allocated, comprising: a plurality of CDMA transmitting stations and a single CDMA receiving station, all of which are intercoupled to each other over a CDMA channel and a feedback channel; each CDMA transmitting station including a control circuit which sends control signals on said CDMA channel in spaced apart time intervals which request respective bit rates on said CDMA channel; said CDMA receiving station including a bit rate allocating circuit which receives and responds to said control signals by sending feedback messages over said feedback channel that address individual CDMA transmitting stations and grant respective bit rates to the addressed station; said bit rate allocating circuit also including a circuit that tallies the bit rates which are granted in said feedback messages, and maintains the tally below a predetermined maximum aggregate bit rate for said CDMA channel; and, each CDMA transmitting station including a receiver circuit that receives those feedback messages which address that particular station, and a data transmitting circuit which sends CDMA digital data on said CDMA channel at the bit rates granted in the received feedback messages.
