Abstract
A method of assigning transmission data rate in a multi-channel communication system based upon a comparison between projected transmitter power output for transmission at a selected data rate, and the maximum transmitter power capability. Relative power requirements for high and low processing gain channels are stored in a LUT in memory, for a variety of data transmission rates. By accessing the LUT, the relative power required for transmission over a low processing gain channel at a selected data rate can be determined. This power is then added to the current output power required by active high processing gain channels to determine the projected output power required once the low processing gain, or data, channel is brought online at the selected data rate. Data rate is increased or decreased until the projected output power is within a pre-selected transmitter output power tolerance, then that data rate is proposed to the receiver.
