Rajala: "Its like saying "our patent covers all methods that transfers driver response to the engine rev speed". EXACTLY!! A dominant patent covers a majority of the methods of performing some technique. If Q was the first to invent power control in a wireless system, they have the dominant patent. Period. This is likely to have been the case since CDMA's near-far problem was a problem that others would not experience with TDMA/FDMA or AMPS. Other technologies provided sufficient "gaps" between subscribers by dividing the spectrum into time slots or frequency slots. CDMA was the first wireless system to divide a frequency into code slots. Power control became necessary because the more powerful subscribers near the base station had to have their power turned down while the far away subscribers need the power turned up. Power control in a wireless system was not necessary prior to CDMA so, of course, it would not be surprising if Q invented it and patented the technique. If this is the case, they would likely have the dominant patent and have rights to much more than one or two ways to do power control. Hope that helps. IMHO
