A wireless device can perform non-line-of-sight detection. The wireless device may establish a wireless link with another wireless device using a wireless channel. The wireless device may perform one or more channel measurements for the wireless channel. The wireless device may determine whether a line-of-sight path is available for the wireless channel based at least in part on the one or more channel measurements. The wireless device may determine whether to trigger beamforming selection, antenna selection, and/or any other link maintenance operations based at least in part on the determined line-of-sight availability.

Non-line-of-sight detection

A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

Transmission power management for concurrent operating radios

The disclosed computer-implemented method may include accessing various portions of contextual information based on at least one touch input from a touch-based sensor on a mobile electronic device. The method may next include determining, based on the contextual information, which of different operational antenna parameters associated with at least one antenna of the mobile electronic device are to be changed. The method may then include changing the specified operational parameters associated with the antenna on the mobile electronic device according to the determination. Various other methods, systems, and computer-readable media are also disclosed.

Context-aware antenna tuning

A wireless communication system is presented for multiple wireless technology coexistence in a mobile device. A method according to this application might include obtaining one or more transmit allocation parameters for a wireless transmission via a first radio technology at a first wireless processor and the preparing to receive wireless data via a second radio technology at a second wireless processor. Next, the exemplary method might request that the wireless transmission be deferred, followed by deciding whether to grant the deferral request based at least on the one or more transmit allocation parameters.

Conditional transmission deferral for dual wireless band coexistence

A user device having a dielectric carrier, a multi-band slot antenna, a reflector and a feed line connector is described. The multi-band slot antenna has slot openings in a second portion of conductive material disposed on a second side of the user device and is operable to radiate electromagnetic energy. The reflector is additional conductive material disposed on the second side and is operable to reflect a majority of the radiated electromagnetic energy away from the user device in a first direction.

Reflectors for reflecting electromagnetic energy away from a user device in a first direction

A wireless electronic device having first and second baseband processors is provided. In one suitable arrangement, radio-frequency power splitters and adjustable low noise amplifiers may be form in the receive paths. The use of power splitters allow signals associated with the first and second baseband processors to be received in parallel. In another suitable arrangement, radio-frequency switches are used in place of the power splitters. The states of the switches may be controlled using at least one of the first and second baseband processors. The use of switches instead of power splitters requires that wake periods associated with the first baseband processor and wake periods associated with the second baseband processor are non-overlapping. To ensure minimal wake period collision, a wake period associated with the second baseband processor may be positioned at a midpoint between two successive wake periods associated with the first baseband processor.

Coordinated signal reception across integrated circuit boundaries

A user device having a non-radiating exciter operatively coupled to feed a multi-band aperture antenna is described.

Antenna with an exciter

Electronic devices may have multiple wireless integrated circuits such as a pair of baseband processor integrated circuits and may have multiple antennas such as a pair of antennas. An electronic device may be operated in different modes depending on the operating environment of the electronic device. When both antennas are unblocked, both baseband processors and both antennas may be used in transmitting signals. When one antenna is not available, the device may be operated in a mode in which the available antenna is used and both baseband processors are used or in a mode in which the available antenna is used and only one of the baseband processors is used. Operating mode decisions may be made so as to minimize the potential for intermodulation distortion and absorbed radiation.

Dynamic transmit configurations in devices with multiple antennas

A user device having a multi-band slot antenna with multiple slot openings in conductive material and one or more tuning elements physically coupled to the multi-band slot antenna is described.

Tuning elements for specific absorption rate reduction

Methods for coordinated signal reception across integrated circuit boundaries

Various embodiments are directed to systems and techniques for reducing power consumption in a mobile computing device. In one or more embodiments, a mobile computing device may be arranged to determine a user environment based on detected antenna impedance or detected current. After the user environment is determined, the mobile computing device may confirm that total radiation power (TRP) for the mobile computing device at an initial conducted power level exceeds the minimum TRP threshold required by the network carrier to receive acceptable quality of service (QoS). Based on the excess TRP for the particular user environment, the mobile computing device may determine a reduced conducted power level to be input to an antenna system. Accordingly, significant power savings may be achieved. To save additional power, the mobile computing device may automatically adjust and/or improve antenna impedance matching based on user environment allowing a further reduction in conducted power.
