Patent ID: 8412258

Claim:
A method for adjusting a setpoint that is used to control a transmit power of a wireless signal, said method comprising: receiving said wireless signal to obtain a received signal; determining an observed error level in said received signal; selecting an adjustment increment, wherein selecting said adjustment increment comprises: when said observed error level is greater than a target error level, selecting an upward adjustment increment from among at least a first upward adjustment value, a second upward adjustment value, and a third upward adjustment value based on said observed error level, wherein said first upward adjustment value is associated with a first range of observed error levels greater than said target error level, said second upward adjustment value is associated with a second range of observed error levels greater than said target error level, and said third upward adjustment value is associated with a third range of observed error levels greater than said target error level; and when said observed error level is less than said target error level, selecting a downward adjustment increment from among at least a first downward adjustment value, a second downward adjustment value, and a third downward adjustment value based on said observed error level, wherein said first downward adjustment value is associated with a first range of observed error levels less than said target error level, said second downward adjustment value is associated with a second range of observed error levels less than said target error level, and said third downward adjustment value is associated with a third range of observed error levels less than said target error level; and adjusting said setpoint by said selected adjustment increment.
