Abstract:
1. A method of controlling reverse link interference in a sector of a base station of a CDMA communication system, the method comprising: for each access terminal of a plurality of access terminals in communication with the base station, determining a noise power spectral density at the base station (i) due to a thermal noise power spectral density and (ii) due to a sum of chip energy of selected channels of access terminals that are power controlled by the sector, thereby obtaining a plurality of determined noise power spectral densities, one determined noise power spectral density per said each access terminal of the plurality of access terminals in communication with the base station; determining a maximum noise power spectral density among the plurality of determined noise power spectral densities; and controlling reverse link power of one or more of the access terminals that are power controlled by the sector based upon the maximum noise power spectral density.
