Abstract:
1. A method for estimating a signal-to-interference ratio in a cellular communication system having interfering signals and employing interference cancellation techniques for mitigating said interfering signals, the method being implemented by a node in the cellular communication system and comprising: obtaining a signal value representing power of a first signal; obtaining at least one precancellation interference value representing powers of signals interfering with said first signal before said interference cancellation is employed; predicting, as a function of said at least one precancellation interference value, a postcancellation interference value representing a sum of powers of signals interfering with said first signal after said interference cancellation is employed; and estimating the signal-to-interference ratio as a ratio between said signal value representing said power of said first signal and said predicted postcancellation interference value.
