Abstract
A method for noise rise estimation in a wireless communication system comprises measuring () of received total wideband power of an antenna a plurality of times. An estimate of a noise floor measure is computed () based on at least a number of the measured received total wideband powers of the antenna. Interference whitening of a received signal is performed () per user for a multitude of users. A useful signal power per user after the interference whitening, preferably Frequency Domain Equalization, is determined (). A noise rise measure per user is calculated (), based at least on the useful signal power per user and the noise floor measure. The calculation in turn comprises compensation of the noise rise measure per user for the effects of the interference whitening. An arrangement for noise rise estimation is adapted for such a method. A radio base station comprises such an arrangement.
