The disclosure relates to techniques for controlling Specific Absorption Rate (SAR) of radio energy transmission. In particular, the disclosure relates to a radio device and a method for controlling radio energy transmission of a plurality of radio entities to comply with a predefined SAR requirement. Such a radio device includes: a plurality of radio entities configured to transmit radio energy; and a controller configured to control the radio energy transmission of the plurality of radio entities to comply with a predefined Specific Absorption Rate, SAR, requirement, wherein the controller is configured to enable at least two radio entities of the plurality of radio entities operating concurrently based on a shared SAR transmission power restriction which allows the at least two radio entities transmitting concurrently at a predefined duty cycle, in particular at 100% duty cycle, without violating the SAR requirement. The disclosure further relates to a method for dynamic management of a SAR budget across multiple radio entities.
