Abstract:
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:determining a carrier signal strength (C) of a received signal and an interference level (I) at said radio receiver; calculating a carrier-to-interference ratio (C/I) at said radio receiver; comparing the carrier-to-interference ratio (C/I) to a predefined target value; and if the carrier-to-interference ratio (C/I) is less than said predefined target value, increasing the size of said radio receivers uplink power window; otherwise, if the carrier-to-interference ratio (C/I) is greater than said predefined target value, decreasing the size of said radio receiver's uplink power window.
