ABSTRACT:
Radio communication apparatus for transmitting control data, comprising output power amplifying means responsive to a control signal from an output power control means for varying a predetermined output power level from the output power amplifying means in accordance with a sequence of power levels indicative of a control message. The predetermined output power level is selectable from a range of predetermined power levels and may be variable between power levels of adjacent predetermined power levels for the range of predetermined power levels. Typically, the control message is a request to vary the output power level for inhibiting radio signal fading.
