1. A method of estimating a quality of a signal, the method in a first device comprising:
- measuring a signal transmitted from a second device to a third device, such that the first device is not serving the second device or the third device at the time of the measuring;
determining a value of a metric from an autocorrelation function of the measured signal and adjusting the value of the metric, to create an adjusted metric, based on a function of a peak to average power ratio of the measured signal; and
determining an estimate of the quality of the signal from the adjusted metric.

22. A method of estimating a quality of a signal, the method in a first base station comprising:
-
measuring a signal transmitted from a mobile device to a second base station that is serving the mobile device, such that the mobile device is not being served by the first base station; determining a value of a metric from an autocorrelation function of the measured signal; adjusting the value of the metric based on a function of a peak to average power ratio of the measured signal to create an adjusted metric and determining an estimate of the quality of the signal from the adjusted metric. - View Dependent Claims (24)
