Abstract
A method for load scheduling in a WCDMA communication system utilizing GRake equalizing radio reception comprises estimating (210) of channel estimates for a plurality of users. Combining weights are established (220) for a GRake equalizing reception for the present received uplink digital radio signals. Function parameters of a predicted future load measure function is predicted (230) as a function of individual grants of the plurality of users based on at least the channel estimates and the combing weights, taking sensitivity for interference suppression provided by the GRake equalizing for each of the plurality of users into account. The predicting further comprises adaptation of the function parameters for changed load equilibrium levels caused by the individual grants of the plurality users. A set of grants for the users is selected (240) based on the future load measure function. Uplink load is scheduled (250) according to the selected set of grants.
