Claim Text:
1. A method for noise rise estimation in a wireless communication system, said method comprising the steps of: measuring received total wideband power a plurality of times; computing an estimate of a noise floor measure based on at least a number of said measured received total wideband powers; performing an interference whitening based on one of GRAKE, GRAKE+ and chip equalizer for a first user; determining a useful signal power for said first user after interference whitening; deriving a first user noise floor compensation factor based on combining weights for said first user used in said interference whitening; obtaining a code power to interference ratio measure for said first user; calculating a noise rise measure for said first user, based at least on said useful signal power for said first user after interference whitening, said first user noise floor compensation factor, said code power to interference ratio measure for said first user and said noise floor measure; repeating the steps of performing, determining, deriving, obtaining and calculating for each of a plurality of users; and defining a system noise rise measure based on said noise rise measures for said plurality of users.
