Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.
