All refrences to claim(s) which appear below refer to the numbering after this setence.
1. In a communication system, a method for controlling gain of a supplemental channel comprising:
determining gain level of a fundamental channel (Gfch), wherein said fundamental channel is associated with said supplemental channel for being targeted for a common receiving station;
determining an adaptive margin (Ma) for said supplemental channel;
determining a supplemental channel gain (Gsch) based on said Gfch and said Ma.
2. The method as recited in claim 1 further comprising:
transmitting said supplemental channel at said Gsch level.
3. The method as recited in claim 1 further comprising:
determining a data rate factor based on a data rate of said fundamental channel and data rate of said supplemental channel, wherein said Gsch is based on said data rate factor.
