摘要： An uplink power control technique may include a simplified maximum sector throughput (SMST) and a generalized maximum sector throughput (GMST). The SMST and GMST techniques may be used to determine a maximum sector throughput and cell-edge throughput to enhance the overall efficiency of the communication system. The uplink power control technique may determine the optimal uplink power value without collecting interference over thermal noise and without computing the individual channel losses in each neighboring sector.

摘要： Briefly, in accordance with one or more embodiments, one or more interference over thermal noise (IoT) values may be measured for one or more frequency partitions or a sounding area, or combinations thereof, and a difference between a current IoT value and a previous IoT value may be evaluated. If the difference is greater than or equal to a reset threshold, the current IoT value is broadcast to a mobile station to reset the IoT value. Otherwise an IoT differential value is broadcast to the mobile station to update the IoT with the IoT differential value. The mobile station may then perform open loop power control based on the IoT value for uplink broadcast.

摘要： Techniques are described that can be used to determine a transmitter power level of a mobile station based on spectrum efficiency gain and loss. Spectrum efficiency gain is measured for a home sector base station. Spectrum efficiency loss is measured for base stations other than the home sector base station. In one example, a base station transmits information such as noise plus interference level to a mobile station and the mobile station determines the transmitter power level. In another example, the mobile station transmits information such as preamble signal strength and preamble total signal strength to the home sector base station and the home sector base station determines the transmitter power level and instructs the mobile station to apply the determined transmitter power level.
