<p>In a time division multiple access (TDMA) based cellular radio telecommunications system, system performance is improved by adjusting the transmit power associated with certain downlink signals during a corresponding timeslot, and in such a way that the power adjustment resembles that of a typical fading event, in terms of both time of occurrence and rate of occurrence (e.g., dB per msec). During the same timeslot, the transmit power is associated with other downlink signals is maintained at a substantially constant level. More particularly, the transmit power associated with a downlink signal is maintained at a substantially constant level if the power level does not sufficiently provide adequate signal quality for the corresponding mobile station in the presence of fading. In contrast, the transmit power associated with a downlink signal may be adjusted (e.g., attenuated) in such a way that it resembles that of a typical fading event if the transmit power associated with the downlink signal provides more than adequate signal quality for the corresponding mobile station, despite the power level adjustment and the presence of fading.</p> |
