Abstract: Methods and devices configured to apply a power back-off (PBO) to limit a radio frequency (RF) transmitter power up to a first limit, where the first limit is below a pre-defined RF power limit; accumulate a difference between RF transmission power spent transmitting data and the pre-defined RF power limit over a duration to produce an accumulated energy budget; and once the accumulated energy budget reaches a pre-defined energy credit value, remove the PBO and allow RF transmitter power exceeding the pre-defined RF power limit until the accumulated energy budget meets a threshold.

Abstract: Device and methods to receive an instruction to apply a requested power back-off (PBO) for transmitting a data packet at an adjusted transmission power adapted from a current transmission power; estimate a first energy quantity for transmitting the data packet based on the adjusted transmission power and a first estimated length of time for transmitting the data packet at the adjusted transmission power; determine the second transmission power that is greater than the adjusted transmission power and estimate a second energy quantity based on the second transmission power and a second estimated length of time for transmitting the data packet at the second transmission power, where the second energy quantity is less than the first energy quantity; and apply the second PBO based on the second transmission power for transmitting the data packet instead of applying the requested PBO.

Abstract: To control transmit power in a wireless device, the wireless device sends a data indication signal to the network adaptor. The data indication signal can indicate a transmission status of data to be transmitted and being located in at least one queue of a network stack of a computing device of wireless device. The network adaptor can determine using a time-averaged specific absorption rate (SAR) function, a transmit power for wireless transmission of data in the network adaptor by considering at least the data in the network adaptor and the at least one data indication signal.

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: Devices and methods for providing communication channel congestion levels to determine whether to apply power and/or time back-offs, and if so, how to apply said back-offs. The device may be configured to estimate a congestion level of a communication channel, wherein the congestion level indicates an availability for transmissions over one or more time periods; determine a projected time back-off for an ensuing packet transmission based on the congestion level; and determine whether to apply a transmission back-off based on the projected time back-off and a transmission energy budget based on one or more time-averaging specific absorption rate (TAS) parameters for regulating a radiation exposure to a user of the device.

Abstract: A device including one or more processors configured to: determine a disconnection margin value based on: a current transmission operation state including one or more transmission control parameters, and a current transmission rate; receive a power back-off (PBO) request including a PBO value; perform a comparison of the PBO value to the disconnection margin value; and determine whether to apply a PBO according to the PBO request based on the comparison.

Abstract: Devices with radiating antennas are subject to various regulations designed to limit the absorption of radiofrequency energy in a human body part in close proximity to a radiating antenna. Various conventional strategies are available for management of transmissions to comply with these regulations; however, each of these conventional strategies has drawbacks, such as a negative effect on the wireless link. Various strategies are disclosed herein to comply with the requisite regulations while maintaining the wireless link. In addition, strategies are presented to select wireless link rates, taking into account limitations that may be in place to satisfy the necessary regulations.
