    Abstract: Obstruction detecting logic may execute touch-sensing algorithms on the electronic device, which may detect when a user is gripping the electronic device from the side, when the fingers or hand of the user is on the edge of the electronic device, when the user is using one or more fingers to touch the electronic device, and may determine thumb and finger orientation. Using the touch-sensing methods, it may be determined which antennas are obstructed. To mitigate negative antenna performance due to the determined obstruction, one or more compensation actions may be taken. The touch-sensing algorithms may estimate user thumb/finger orientation and velocity, which may be used to predict future antenna occlusion (e.g., if the hand of the user is in motion).

    Abstract: This disclosure is directed to shared antenna tuning. An electronic device may receive a global navigation satellite system (GNSS) tune request to tune a shared antenna to a GNSS signal frequency. The electronic device may then tune the antenna to the GNSS signal frequency and enable a GNSS receiver. The electronic device may also receive a cellular tune request to tune the antenna to a cellular frequency. The electronic device may tune the antenna to a cellular frequency and may deactivate the GNSS receiver or blank the GNSS receiver. In some embodiments, the electronic device may also communicate with a Low Earth Orbit (LEO) satellite. During LEO satellite communication, the electronic device may transmit a signal to blank a GNSS L1 receiver to avoid signal interference with the LEO satellite communication, and activate a GNSS L5 receiver to receive GNSS signals.

    Abstract: In some implementations, the disclosed techniques may include tuning a first antenna element to a first tuning state during an acquisition mode for establishing communication channels with satellites. The first tuning state can configure the first antenna element to receive signals in a first frequency range. The techniques may include establishing the communication channels using the first antenna element in the first tuning state during the acquisition mode. The techniques may include transitioning from the acquisition mode to a tracking mode. The techniques may include changing the tuning state of the first antenna element. The techniques may include determining a location of the mobile device during the tracking mode: (1) using the first antenna element and a second antenna element of the mobile device or (2) not using the first antenna element and using the second antenna element that is configured to receive signals in a second frequency range.
