A method of a receiver (28; 30; 500) for measuring a received power for handover measurements of at least one signal having a pattern known to the receiver, the signal having been transmitted by at least one antenna (16; 18; 20; 22; 24; 26; S1; S1; S3; S4; S5), the method comprising: using a first method of measuring the received power based on the pattern, the first method generating a first sequence of first power estimates; determining whether a predetermined first event has occurred by determining that a measured signal power meets a first condition; and if the first event has occurred, changing to a second method of measuring the received power, the second method being different from the first method and generating a second sequence of second power estimates such that computationally intensive channel and signal-power estimation methods are used only when the first event has occurred, where the computationally intensive estimation methods include that estimation is based on Wiener filtering, wherein whether the first event has occurred is determined based on the first sequence of first power estimates, and the first method includes coherent averaging of a number M of received reference symbols followed by non-coherent averaging of N coherent averages, and the method further comprises: if a change to the second method has occurred, determining whether a predetermined second event has occurred based on the second sequence of second power estimates by determining that the measured signal power meets a second condition; and if the second event has occurred, changing back to the first method of measuring the received power. using a first method of measuring the received power based on the pattern, the first method generating a first sequence of first power estimates; determining whether a predetermined first event has occurred by determining that a measured signal power meets a first condition; and if the first event has occurred, changing to a second method of measuring the received power, the second method being different from the first method and generating a second sequence of second power estimates such that computationally intensive channel and signal-power estimation methods are used only when the first event has occurred, where the computationally intensive estimation methods include that estimation is based on Wiener filtering, wherein whether the first event has occurred is determined based on the first sequence of first power estimates, and the first method includes coherent averaging of a number M of received reference symbols followed by non-coherent averaging of N coherent averages, and the method further comprises: if a change to the second method has occurred, determining whether a predetermined second event has occurred based on the second sequence of second power estimates by determining that the measured signal power meets a second condition; and if the second event has occurred, changing back to the first method of measuring the received power. if a change to the second method has occurred, determining whether a predetermined second event has occurred based on the second sequence of second power estimates by determining that the measured signal power meets a second condition; and if the second event has occurred, changing back to the first method of measuring the received power.
