Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Abstract: A method for controlling transmission power in accordance with a total transmission power limit in a multi-radio wireless communication device including a master radio and a slave radio is provided. The method can include the wireless communication device determining, at the master radio, a transmission power of the master radio. The method can further include the wireless communication device providing information indicative of the transmission power of the master radio from the master radio to the slave radio. The method can additionally include determining, at the slave radio, an allowable transmission power for the slave radio. A sum of the allowable transmission power and the transmission power of the master radio may not exceed the total transmission power limit.

Abstract: A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.
