The invention relates primarily to power convergence systems for 3GPP radio links and addresses a difficulty encountered with such links, namely the speed at which the appropriate power control level for given up-link and/or down-link transmissions can be established by conventional procedures. The rapid establishment of correct power levels is important, since operation with inappropriate power levels results in data loss and/or data errors if the levels are too low and causes interference, leading to loss of data capacity for the cell in question and neighbouring cells, if the levels are too high. The invention provides a power convergence system for a radio link wherein control information relevant to the convergence process is transmitted in preference to at least some traffic control data until convergence is established, and which thus effects acceleration of convergence at the expense of delaying the onset of fully controlled traffic flow. The control may be exerted in steps whose amplitude is preferably transmitted as coded data.
