International Classification:

H04B 1/3827
H04W 52/36

Abstract:

Methods and device to implement the use of proximity sensor data and time-averaging specific absorption rate methods in determining whether to apply or remove a power back-off to a radio frequency transmitter. The methods and devices may be configured to detect whether a body is proximately located based on obtained proximity sensor data; define an upper threshold for a radio frequency (RF) transmit power and a lower threshold for the RF transmit power; calculate an average power of an RF transmitter over a fixed time period; and based on whether the body is detected, the average power, and a comparison of the average power to the upper threshold or the lower threshold, determine whether to apply or remove a power back-off to the RF transmitter.

International Classification:

H04W 74/08
H04W 80/02
H04W 4/40

Abstract:

The present disclosure describes co-channel coexistence mechanisms for mitigating interference between multiple radio access technologies (RATS) that operate in the same or neighbouring channels, frequency bands, and/or bandwidths. The co-channel coexistence mechanisms include variable transmission intervals including variable gaps or guard periods, and utilizing network allocation vectors (NAV). Other embodiments may be described and/or claimed.

International Classification:

H04W 52/18

Abstract:

Transmission power control methods and devices are described. In a transmission power control method, a specific absorption rate (SAR) is calculated based on a transmission power of the communication device and a proximity distance of the communication device with an external object. A time average specific absorption rate can be calculated based on the SAR. A power absorption budget value can be calculated based on the time average specific absorption rate and a time average specific absorption rate threshold value. Further, the transmission power of the communication device can be adjusted based on the power absorption budget value.

International Classification:

H02J 50/60
H02J 50/12
H02J 7/02
H04B 5/00

Abstract:

Techniques for proximity sensing in a wireless power transmitter in a system, method, and apparatus are described herein. For example, an apparatus may include a transmitter coil configured to generate a magnetic field. The apparatus may also include a controller configured to reduce a strength of the magnetic field based on a proximity detection of an object.

Abstract:

This disclosure describes methods, apparatus, and systems related to a maximum coil current system. A device may determine a presence of a first device placed on a charging area of the device, the charging area including a power transmitting surface. The device may establish a connection with the first device using one or more communication protocol. The device may identify device information associated with the first device using the established connection. The device may determine a maximum charging current for the first device based at least in part on the device information.
