摘要
A method and system for identifying passive intermodulation, PIM, at a base station in a wireless communication system are disclosed. In some embodiments, a method includes measuring the noise floor in a radio frequency, RF, channel of an uplink carrier, the uplink carrier comprising a carrier transmitted from a wireless device to the base station. The method includes comparing the measured noise floor to a predetermined noise floor. The method also includes determining whether PIM is present based on a result of the comparison.
