Abstract: A method of operating a user equipment for measuring non-contiguous carriers comprises: changing a position of a local oscillator to be in the middle of the non-contiguous carriers; measuring the carriers simultaneously; estimating a power level of an interferer in a gap in the non-contiguous carriers which creates image interference; and compensating the measurement dependent on the interferer power level and an image rejection factor.

Abstract: A method of controlling a frequency selection of a PLL used in cooperation with a device of a wireless communication network, such as a Universal Mobile Telecommunication System (UMTS) network, the method comprising:—receiving a first set of signal measurements;—comparing the first set of signal measurements with a first threshold and, selectively switching the PLL frequency from a first value to a second value as a result of the comparison of the first set of signal measurements with the first threshold;—further receiving a second set of signal measurements; and,—comparing the second set of signal measurements with a second threshold, different from the first threshold, and selectively switching the PLL frequency from the second value to the first value as a result of the comparison of the second set of signal measurements with the second threshold.
