Macro-femto inter-cell interference mitigation

摘要

A method for managing signal interference is provided. The method comprising receiving a signal, wherein the signal comprises at least an interfering reference signal from an interfering network interface and a serving reference signal from a serving network interface, and wherein the interfering signal interferes with the serving signal; identifying a power level and offset of the interfering reference signal and a power level and offset of the serving reference signal; comparing the interfering power level and offset to the serving power level and offset to form a comparison; and performing a corrective action based on the comparison.

1. A method for managing signal interference, the method comprising:
receiving a reference signal comprising at least an interfering reference signal from an interfering network interface and a serving reference signal from a serving network interface, and the interfering reference signal interferes with the serving reference signal; identifying a power level of the interfering reference signal and a power level of the serving reference signal; and comparing the interfering power level to the serving power level to form a comparison; wherein the identifying comprises: identifying an offset of the interfering reference signal and an offset of the serving reference signal; and wherein the comparing comprises: determining whether the offset of the serving reference signal is more than a threshold number of symbols away from the offset of the interfering reference signal; and responsive to the offset of the serving reference signal not being more than the threshold number of symbols away from the offset of the interfering reference signal, determining a relation of the interfering power level to the serving power level based on the comparison.
