Abstract

Transmission power control methods and devices are described. In a transmission power control method, a specific absorption rate (SAR) is calculated based on a transmission power of the communication device and a proximity distance of the communication device with an external object. A time average specific absorption rate can be calculated based on the SAR. A power absorption budget value can be calculated based on the time average specific absorption rate and a time average specific absorption rate threshold value. Further, the transmission power of the communication device can be adjusted based on the power absorption budget value.
