1. A method of managing communications in a wireless network, the method comprising:
- measuring an aggregate energy-to-interference of an air interface, the aggregate energy-to-interference being between a base station and a plurality of mobile stations;
(i) based on the aggregate energy-to-interference of the air interface being greater than an aggregate set point;
selecting a first data rate for signals transmitted from the base station to the plurality of mobile stations; and
causing the signals from the base station to the plurality of the mobile stations to be transmitted at the first data rate;
(ii) based on the aggregate energy-to-interference of the air interface being less than the aggregate set point;
measuring an energy-to-interference of the air interface, the energy-to-interference being between the base station and one of the plurality of mobile stations;
(a) based on the energy-to-interference of the air interface being less than an individualized set-point;
selecting a transmit power for the signals transmitted from the base station to the one of the plurality of mobile stations; and
causing communications from the base station to the one of the plurality of mobile stations to be at the transmit power; and
(b) based on the energy-to-interference of the air interface being greater than the individualized set-point;
selecting a second data rate for signals transmitted from the base station to the one of the plurality of mobile stations; and
causing the signals from the base station to the one of the plurality of mobile stations to be transmitted at the second data rate.

Abstract
A method and system for managing communications over an air interface of a wireless network. A base station may measure a level of interference over the air interface. Based on the level of interference, the base station may adjust a data rate and a transmit power of signals transmitted over the air interface.
