摘要：
A method, performed by a user equipment, UE (14), in a serving cell for performing link measurements in a wireless communication network, the method comprising:
determining a snapshot value of a serving link signal received quality while the UE (14) is permitted to refrain from performing neighbor link measurement;
updating the snapshot value with a further serving link signal received quality if the further serving link signal received quality is raised above the current snapshot value and while the UE (14) is permitted to refrain from performing neighbor link measurements; and
responsive to detecting, while the UE (14) is permitted to refrain from performing neighbor link measurement, that signal received quality of the serving link has dropped by at least a threshold amount below the snapshot value, performing (104) neighbor link measurements.
