LOAD ESTIMATION IN WIRELESS COMMUNICATION |
摘要 |
<p>A method for noise rise estimation in a wireless communication system comprises measuring (210) of received total wideband power a plurality of times and computing (212) an estimate of a noise floor measure based on a number of the measured received total wideband powers. An interference whitening is performed (214) based on one of GRAKE, GRAKE+ and chip equalizer. A useful signal power for the first user after interference whitening is determined (216). A first user noise floor compensation factor is derived (218) based on combining weights for the first user used in the interference whitening. A code power to interference ratio measure for said first user is obtained (220). A noise rise measure is calculated (222), based at least on the useful signal power for the first user after interference whitening, the first user noise floor compensation factor, the code power to interference ratio measure for the first user and the noise floor measure.</p> |
