摘要： In certain aspects, a method implemented in a wireless device includes determining a specific absorption rate (SAR) distribution for a first wireless communication technology, determining a power density (PD) distribution for a second wireless communication technology, and combining the SAR distribution and the PD distribution to generate a combined RF exposure distribution. The method also includes determining at least one first maximum allowable power level and at least one second maximum allowable power level for a future time slot based on the combined RF exposure distribution, setting at least one transmission power limit for a first transmitter in the future time slot based on the at least one first maximum allowable power level, and setting at least one transmission power limit for a second transmitter in the future time slot based on the at least one second maximum allowable power level.

摘要： Some disclosed devices include an inertial sensor system, a proximity sensor system, an antenna system configured to transmit and receive radio signals and a control system. The control system may be configured for receiving inertial sensor data from the inertial sensor system and controlling the proximity sensor system and/or the antenna system based, at least in part, on the inertial sensor data. In some examples, the control system may be configured for controlling the proximity sensor system and/or the antenna system based, at least in part, on whether the inertial sensor data indicates that the device is being held, is being carried or is on a person's body (e.g., is in the person's pocket).

摘要： Aspects described herein include methods and devices for radar integration with a mmW communication module. In some aspects, an apparatus is provided that includes a millimeter wave (mmW) printed circuit board (PCB), with first and second mmW elements, and a radar antenna. The first mmW element is coupled to a first side of the mmW PCB, where the first mmW element is configured for wireless mmW communications at frequencies above approximately 24 gigahertz (GHz). A second mmW element coupled to the first side of the mmW PCB, where the second mmW element is positioned adjacent to the first mmW element and is separated from the first mmW element by a gap spacing. A radar antenna is disposed in the mmW PCB and aligned with the gap spacing between the first mmW element and the second mmW element.

摘要： 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.

摘要： Methods, systems, and devices for wireless communication are described. A network server may configure a base station for beamforming communications based on a service type of data used by a user equipment (UE). The network server may determine the service type of the data based on position data of the UE, along with other statistical information related to data usage. The position information may include global position system (GPS) information, gyroscope information, accelerometer information, or information related to the UE's subarray geometry. The base station may receive the position information from the UE and convey it to the network server. The network server may use the position information to generate a network map and to identify the service type of communication.

摘要： 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.
