Abstract
A method for noise rise estimation in a wireless communication system comprises receiving () of radio signals. An interference whitening () is performed. A useful signal power for a first user after the interference whitening is determined () for a plurality of time instances. Furthermore, a first user noise floor compensation factor is derived () based on combining weights for the first user used in the interference whitening. A probability distribution for a compensated useful signal power for the first user is estimated (). A conditional probability distribution of a noise floor measure is computed (). A noise rise measure for the first user is then calculated () based at least on the compensated useful signal power for the first user and the conditional probability distribution of a noise floor measure.
