A wireless communication device includes one or more processors, configured to determine one or more first transmission power measurements within a first transmission power measurement sampling period; calculate a first transmission power factor, the first transmission power factor representing a central tendency of the one or more first transmission power measurements from the first power measurement sampling period; determine a second power measurement during a second transmission power measurement sampling period; and calculate a second transmission power factor, wherein the second transmission power factor is a central tendency of at least one of the one or more first power measurements and the second power measurement.
