Claim Text:
1. A method for controlling multiple input multiple output, MIMO, channel boosting, 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; 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; wherein the steps of determining the boosting parameter further comprises: determining the boosting parameter to be a default value of 127 when the boosting parameter fails to be signaled by higher layers and when the rank is one; and determining the boosting parameter to be less than or equal to zero for at least the S-DPCCH when the rank is two or more; and applying the boosting parameter affecting power boosting to at least one uplink transmission, wherein the boosted power used on each uplink transmission is utilized by a base station to decode data and to perform channel estimation.
