A noise rise estimation method calculates (230) a noise rise measure suitable for stability control purposes, based at least on a useful signal power for the first user after interference whitening, a first user noise floor compensation factor, a code power to interference ratio measure for the first user, a noise floor measure and an estimated neighbour cell interference power. These factors are provided by measuring (210) received total wideband power and generating (212) a measure of an own cell power. An estimate of the noise floor measure is computed (214) and the neighbour cell interference power is estimated (216) based on these measurements and generated measures. An interference whitening is performed (220). The useful signal power for the first user after interference whitening is determined (222). The first user noise floor compensation factor is derived (224) based on combining weights for the first user used in the interference whitening. The code power to interference ratio measure for the first user is obtained (226). |
