A wireless communication device and method for filtering a power measurement of a reference signal received by a wireless communication device, by measuring, with a receiver, a current reference signal power and a current cell specific reference signal (CRS) power of the reference signal; generating, by a processor, a measurement reliability coefficient based on the current reference signal power and the current CRS power; and filtering, by a filter, the current reference signal power using the generated measurement reliability coefficient to generate a filtered reference signal power, wherein the measuring, generating, and filtering are performed in a physical layer.
