ABSTRACT:
Methods and arrangements for providing load reference data in a CDMA wireless communication system with receiver diversity are presented. The method comprises measuring (210) of received total wideband power for more than one receiver branch. Probability distributions for a respective power quantity are estimated (212), related to selected state variables of an estimation algorithm, from quantities representing the measured powers using selected measurement functions of the selected state variables of the estimation algorithm. The selected state variables correspond to cell power quantities and the selected measurement functions correspond to the quantities representing the measured powers. A conditional probability distribution of noise floor measures for the respective branches are computed (214) based on the estimated probability distributions. The method ends with provision (216) of load reference data based on the computed conditional probability distributions of the noise floor measures.
