  • Patent number: 6085107
    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.

  • Patent number: 6028851
    Abstract: A system for inhibiting the transmission of an access request message from a mobile station when either the system is incapable of granting access at the class of service desired by the mobile or access by the mobile at that class of service would increase the interference level of the target base station or a neighboring base station past its interference capacity. In one embodiment, each base station broadcasts a maximum data rate access parameter and any mobile receiving that parameter and seeking access at a greater data rate refrains from transmitting an access request message. In another embodiment, each mobile calculates from its path loss to the base station the power level it must transmit in order to gain access as well as the effect of that transmission on the interference level of both the target base station and neighboring base stations. If transmission at the required power level would increase the interference level of any base station past its maximum capacity, the transmission is inhibited.
