Abstract

It is presented a method for controlling multiple input multiple output, MIMO, pilot channel boosting. The method is performed in a user equipment, UE, capable of MIMO transmissions using a primary and a secondary stream. The method comprising the steps of: determining a rank used for uplink transmissions from the UE; and determining a boosting parameter affecting power boosting of an Enhanced Dedicated Physical Control Channel, E-DPCCH, and a Secondary Dedicated Physical Control Channel, S-DPCCH, based on the rank. A corresponding UE, base station and associated method are also presented.
