Abstract
A method, apparatus, and computer program for controlling transmission power of a radio apparatus are provided. The method includes: determining, in a radio apparatus configured to support a cellular radio access technology in communication with a cellular counterpart apparatus and a short range radio access technology in communication with a short range counterpart apparatus, a maximum total transmit power of the radio apparatus; causing the radio apparatus to use a first transmit power level in transmission to the cellular counterpart apparatus; determining a remaining transmission power margin by computing a difference between the maximum total transmit power and the first transmit power level; and causing the radio apparatus to autonomously limit a second transmit power level to fall within the remaining transmission power margin and to use the second transmit power level in transmission to the short range counterpart apparatus.
