Abstract:
1. A method in a radio base station (RBS) for handling load coupling in softer handover, the method comprising: receiving signals from a plurality of User Equipments (UEs) connected to the RBS, using a category 1 receiver, a category 1 receiver being an interference cancelling or interference suppressing receiver; determining the load experienced by the respective UEs; estimating the effect of load coupling, introduced by the category 1 receiver, in softer handover of at least one of the UEs connected to the RBS, load coupling implying a coupling of load between cells or cell sectors controlled by the same RBS; and, when the estimated effect of load coupling of a UE fulfills a predefined criterion, modifying at least one entity in the RBS, such that the effect of load coupling is reduced or avoided.
