Abstract
Abstract A radio communication method and system employs power level presetting to mitigate the increase in interference caused by the discontinuous transmission of mobile stations. In the downlink, power presetting entails detecting the entry (or removal) of mobile stations to a cell, and in response thereto, calculating a plurality of power adjustment values for each mobile station within the cell. In the uplink, power presetting entails estimating an increase in interference caused by the entry (or removal) of mobile stations to a cell, and using this estimate for calculating an updated power target for each mobile station within the cell. Power presetting is also initiated in response to one or more mobile stations switching from high data-rate mode to low data-rate mode, or vice versa.
