Abstract: This disclosure presents methods and devices that implement dynamic transmit power control techniques in terminal devices with multiple radio frequency (RF) transmitters and/or in a multi-terminal device environment to comply with regulatory RF exposure limits and standards while enhancing device performance. For example, the present disclosure provides a device including a processor configured to monitor a transmit power for each of a plurality of transmitters; determine a transmit power reduction to be applied to the plurality of transmitters based on a total simultaneous transmit power of the plurality of transmitters exceeding a threshold; define a respective amount of the transmit power reduction to be applied to each transmitter of the plurality of transmitters based on one or more parameters; and apply the respective amount of the transmit power reduction to each transmitter of the plurality of transmitters.

Abstract: Disclosed herein are devices, methods, and systems for adjusting transmit properties based on compliance metrics for human exposure to radiation. As one example, the system determines a first transmission power limit associated with transmissions on a first radio resource, wherein the first transmission power limit is based on a first compliance level threshold of human exposure to emitted radiation when using the first radio resource. The system determines a second transmission power limit associated with transmissions on a second radio resource, wherein the second transmission power limit is based on a second compliance level threshold of human exposure to emitted radiation when transmitting using the second radio resource. The system also controls a wireless device to select either the first radio resource or the second radio resource for a transmission from the wireless device based on the first transmission power limit and the second transmission power limit.

Abstract: Methods of arranging and designing antennas to optimize electromagnetic field distributions in the near-field region of an antenna to optimize parameters such as electric field (E-field), magnetic field (H-field), specific absorption rate (SAR), power density (PD), etc. while ensuring specific performance of the antenna in the far-field region in terms of gain, efficiency, radiation pattern, etc.
