Abstract: A method and NodeB for assisting, in a first NodeB, in soft handover procedures in WCDMA time division schedules comprises estimating (210) of a high bandwidth neighbour cell interference power for each time division slot. A first change trend of the estimated high bandwidth neighbour cell interference power is computed (212) for each of the time division slots. A future incoming soft handover event of a UE from a neighbour NodeB to the first NodeB, and a future incoming soft handover time for the future incoming soft handover event, is predicted (220). This prediction is based on the first change trend of the estimated high bandwidth neighbour cell interference power. Scheduling of time division slots of UEs is adapted (230) before the predicted future incoming soft handover time. This adaptation is configured to create interference power headroom for the predicted future incoming soft handover event.
