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.
