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 uplink transmissions on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and enhanced Data Channels, E-DCHs are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. When a predetermined minimum E-DPDCH gain factor, ‘smallest quantised βed,k value’, is reached for all E-DPDCH gain factors βed,k, and DTX is applied for all E-DPDCHs, the method comprises applying DTX on E-DPCCH.
