1. A method of controlling power in a cellular telecommunications system that provides high-speed packet data to a multiplicity of mobile stations (MSs) from a serving base station (BS), the method comprising:

  • a) evaluating an expected reception quality for a multiplicity of MSs served by a serving BS;

    b) categorizing the MSs served by the serving BS into a plurality of reception categories that reflect results of the expected reception quality evaluation;

    c) assigning a first one of a plurality of packet data control channels (PDCCHs) preferentially to MSs in a first reception category;

    d) transmitting information on the first PDCCH with a first robustness to MSs in the first reception category; and

    e) transmitting information on a different second PDCCH at a second robustness lower than the first robustness to MSs of a second reception category, such that more transmit power is attributable to the first PDCCH than to the second PDCCH.
