Abstract: 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.

Abstract: Wireless charging, such as that conducted according to standards formed by the AirFuel Alliance and/or various other industry standards for wireless charging, can cause interference with data transfer on a cellular modem of a mobile device. Systems, devices, and methods herein provide power breaks where a power transmitter unit (PTU) will stop generating an electromagnetic field used to charge a power receiver unit (PRU). During the power break, the mobile device can send or receive data over the cellular modem with less or no interference from the wireless charging operations. If the PTU cannot provide a power break, the PRU de-tunes a receive resonator circuit in the PRU to mitigate the interference from the wireless charging operations. Further, the power breaks can also be used by PTUs to scan for near field communication (NFC) tags or devices that could be damaged by wireless charging activities.

Abstract: Techniques for powering up a wireless power receiving device are described herein. An example computing device includes a power receiving unit to wirelessly receive power from a power transmitting unit. The platform hardware includes a System on a Chip (SoC), a multicomm device, and a power sequence manager. The multicomm device is for wireless communication with two or more communication standards. One of the communication standards is used as a side channel for communicating with the power transmitting unit. The power sequence manager component manages activation of platform components of the platform hardware during a low battery cold boot condition. Upon detecting wireless power, the multicomm device is configured to automatically activate and the power sequence manager component is to suppress activation of other platform components of the platform hardware.

Abstract: Methods and apparatus to mitigate coexistence interference in a wireless network are disclosed. An example apparatus includes a station component interface to receive an expected transmission power from an access point; an index processor to determine a set of preferred resource unit (RU) indexes from a set of available RU indexes for at least one of (A) uplink transmission to the access point based on a comparison of allowable transmission power and the expected transmission power or (B) downlink reception based on a comparison of a noise floor to a noise threshold; and the station component interface to transmit a message including the preferred RU indexes to the access point.
