A system and method for uplink power control for aggregated channels in a communication network includes a step 300 of defining power scaling parameters to be used to derive power scaling factors to be applied to associated aggregated uplink channels. A next step 302 includes providing the power scaling parameters to user equipment. A next step 304 includes applying power scaling factors derived from the power scaling parameters to the associated aggregated uplink channels when the user equipment will exceed a maximum transmit power.
