Abstract
A method for noise rise estimation in a wireless communication system comprises measuring () of received total wideband power a plurality of times and computing () of an estimate of a noise floor measure based on at least a number of the measured received total wideband powers. The method further comprises performing () of an interference whitening based on one of GRAKE, GRAKE+ and chip equalizer for a first user and determining () of a user equivalent total wideband power as an available total wideband power after the interference whitening for the first user. The estimate of a noise floor measure is compensated () for the interference whitening into a user equivalent noise floor measure and a noise rise measure for the first user is calculated () based at least on the user equivalent total wideband power and the user equivalent noise floor measure.
