Methods for optimizing an uplink power window associated with a radio receiver, wherein the uplink power window is defined by upper (PU) and lower (PL) power levels. In an exemplary embodiment, the method includes the steps of: i) determining a carrier signal strength (C) and an interference level (I); ii) calculating a carrier-to-interference ratio (C/I); iii) comparing the carrier-to-interference ratio (C/I) to a predefined target value; and iv) if the carrier-to-interference ratio (C/I) is less than the predefined target value, increasing the size of the uplink power window, otherwise, if the carrier-to-interference ratio (C/I) is greater than the predefined target value, decreasing the size of the uplink power window. By using the methods of the present invention, the uplink power window of a radio receiver can be dynamically-adapted to effectively minimize uplink interference while maintaining satisfactory quality of service.
A method for optimizing a radio receiver's uplink power window, said uplink power window defined by upper (PU) and lower (PL) power levels, wherein said radio receiver processes a received signal if the signal strength of said received signal is within said upper (PU) and lower (PL) power levels, said method comprising the steps of:
A wireless communications system radio receiver having an uplink power window defined by upper (PU) and lower (PL) power levels, wherein said radio receiver processes a received signal if the signal strength of said received signal is within said upper (PU) and lower (PL) power levels, said radio receiver comprising:
