Abstract: 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.

Abstract: Methods and device to implement the use of proximity sensor data and time-averaging specific absorption rate methods in determining whether to apply or remove a power back-off to a radio frequency transmitter. The methods and devices may be configured to detect whether a body is proximately located based on obtained proximity sensor data; define an upper threshold for a radio frequency (RF) transmit power and a lower threshold for the RF transmit power; calculate an average power of an RF transmitter over a fixed time period; and based on whether the body is detected, the average power, and a comparison of the average power to the upper threshold or the lower threshold, determine whether to apply or remove a power back-off to the RF transmitter.
