Interference control for CDMA networks using a plurality of narrow antenna beams and an estimation of the number of users/remote signals present

A system for mitigating interference experienced at a receiver in a CDMA cellular network, said CDMA cellular network having at least one base station utilizing a plurality of narrow antenna beams each providing an antenna beam signal suitable for use by said receiver, said CDMA cellular network also having a plurality of mobile units in communication with said base station, said system comprising:

• antenna beam signal attribute adjustment circuitry providing independent adjustment of a preselected attribute of ones of said antenna beam signals;
• antenna beam signal measurement circuitry coupled to ones of said multiple narrow antenna beams accepting said ones of said antenna beam signals, said measurement circuitry providing a measurement signal output including information with respect to measurement of said ones of said antenna beam signals, wherein said measurement signal output is a function of a measured received power and an estimation of a number of remote unit signals present;
• and
• processor based controller circuitry coupled to said measurement circuitry accepting input of said measurement signal output, said controller circuitry also coupled to said adjustment circuitry and providing a control signal output thereto, wherein said controller circuitry provides at least one control signal output according to a predefined protocol to control said adjustment circuitry to adjust at least one selected antenna beam signal of said antenna beam signals as a function of said accepted measurement signal output.
