Abstract
The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and an enhanced Dedicated Physical Data Channel, E-DPDCH are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining (S31) a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced (S32) to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. A DPDCH transmission status is determined (S33), whereupon a power scaling procedure is selected (S34) based on the determined DPDCH transmission status. The selected power scaling procedure is applied (S35) on the uplink transmission.
