  • Publication number: 20240106482
    Abstract: Certain aspects of the present disclosure provide techniques for operating a wireless device pursuant to radio frequency (RF) exposure compliance. A method that may be performed by a wireless device includes switching sensing circuitry to a first mode in response to one or more first criteria being satisfied; switching the sensing circuitry to a second mode in response to one or more second criteria being satisfied; and transmitting a signal at a transmit power determined based at least in part on a radio frequency (RF) exposure limit, and if the sensing circuitry is operating in the second mode, on one or more measurements associated with the sensing circuitry.

  • Patent number: 10595282
    Abstract: Certain aspects of the present disclosure propose methods for determining power level of one or more transmitters based on a power level of a primary transmitter when the transmitters are located in close proximity of each other. The power levels may be determined such that a combined power of all the transmitters is compliant with regulatory radio frequency (RF) safety requirements. For certain aspects, power level of the lower priority transmitters may be determined utilizing one or more look-up tables. For another aspect, power level of the lower priority transmitters may be calculated using an algorithm based on the power level of the priority transmitter. In aspects, the power level of lower priority transmitters and the time duration for which the transmitters are active may be selected dynamically so that the time averaged power of the transmitters for a defined period of time falls below the RF exposure limit.

  • Publication number: 20200021421
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain configurations, the apparatus may be a user equipment (UE). The apparatus may receive configuration information for UL and DL transmissions from another device such as a base station. The apparatus may determine a maximum duty cycle of the UL transmission based on the configuration information. Based on the determined UL maximum duty cycle, the apparatus may determine a transmit power limit for the UL transmission. In one aspect, the apparatus may determine the UL transmit power limit by dividing the power corresponding to a maximum permissible exposure (MPE) limit by the determined maximum UL duty cycle. The apparatus may leverage the forward knowledge of the UL duty cycle to transmit at a power level that complies with the MPE limit while avoiding the poor uplink range associated with static power back-off.

  • Patent number: 10517050
    Abstract: Additional requirements for spectrum emissions may be matched with regional requirements, and an additional maximum power reduction (A-MPR) for a user equipment (UE) may be based on an actual antenna gain of the UE. For example, a UE may be located in a particular region and be required to meet regional requirements for wireless communications. In such cases, the UE may receive network signaling from a base station, and identify an antenna gain for its antenna. The UE may then identify a set of emission requirements based on the identified antenna gain and the network signaling. Additionally, the UE may identify an A-MPR based on the set of emission requirements and the antenna gain and may adjust a maximum output power in accordance with the identified A-MPR. In some examples, an output power threshold may be derived using a difference between a regional requirement and the UE's antenna gain.

  • Publication number: 20190018563
    Abstract: Described herein are systems and methods for monitoring media interactions, and the embodiments disclosed herein are focussed on media interactions at mobile devices. A software application executing at the mobile device is configured to monitor user interactions with the device during that media item playback (using any one or more of the available device inputs, which may include the likes of touchscreens, cameras, buttons, microphones, gyroscopes, and so on). The timing and nature of these user interactions is analysed relative to media event data defined, thereby to identify correlations. The presence/absence of such correlations may be used for a number of purposes, such as media lockout control, competitions/promotions, entertainment provision, data collection/analysis, and the like. One very specific example is to instruct a user to, whilst viewing a football match, touch the location of a particular sponsor's logo (printed on a real-world substrate) each time it appears on screen.
