Disclosed are obstacle detecting methods and apparatuses, the method of detecting an obstacle near a device includes, determining whether to detect an obstacle, detecting the obstacle using communication modules, in response to determining to detect the obstacle, determining whether a result of detecting the obstacle meets a threshold, detecting the obstacle using antennas of a communication module corresponding to a direction of the obstacle from among the communication modules, in response to the result of determining the obstacle meeting the threshold, and outputting a warning signal based on the result of detecting the obstacle using the communication modules or a result of detecting the obstacle using the antennas.

A method for communication processing includes determining a confidence level of an antenna system of a mobile device based on a measured result of the mobile device, determining a communication mode based on the confidence level, and using the communication mode for communication. The communication mode includes an antenna switching mechanism or a diversity mechanism.

Techniques for process based antenna configuration are described, and may be implemented via a wireless device to identify different usage scenarios and to adapt antenna configurations to optimize wireless performance based on the scenarios. For instance, the described techniques enable a wireless device to be calibrated for wireless communication by identifying different obstruction states of a wireless device that correspond to ways that the wireless device is held (e.g., grasped) by a user in different scenarios. The obstruction states are then correlated to antenna positions in the wireless device to prioritize (e.g., activate) antennas that are relatively unobstructed, such as by activating unobstructed antennas and/or deactivating obstructed antennas. Further, calibration can take into specific processes (e.g., applications) and specific users to calibrate an optimize wireless performance based on ways in which a user typically interacts with a process.

Techniques are disclosed for detecting obstruction of a device's antenna(s) and then changing an operation of the device. A transmission time at which an antenna of an electronic device transmitted a signal can be identified. A response signal can be detected that was received at a receiver of the electronic device subsequent to the transmission time. Based on the response signal and on the transmission time, one or more response-signal characteristics can be determined. Based on the one or more response-signal characteristics, it can be determined that the antenna or that another antenna of the electronic device is at least partly blocked from emitting or receiving signals. In response to determining that the antenna is at least partly blocked, a changed type of operation can be identified, and the changed type of operation can be performed.

A device may receive information indicating one or more parameters associated with one or more antenna arrays in a radio access network. The device may receive a flight request that indicates one or more conditions for a flight path of an unmanned aerial vehicle (UAV) seeking network access to the radio access network. The device may determine waypoints for the flight path based on analyzing the one or more parameters associated with the one or more antenna arrays and the one or more conditions for the flight path of the UAV. The device may transmit information identifying the waypoints for the flight path. The device may send control information to cause the one or more antenna arrays to form a corresponding one or more beams along the flight path to enable the UAV to traverse the flight path with the network access to the radio access network.

An electronic device is able to be embedded in a mobile device with a plurality of antennas. The antennas are electrically coupled to the electronic device through a connector. The electronic device includes a plurality of built-in antennas, a communication processor, a plurality of antenna switching circuits, and a control processor. The built-in antennas receive a wireless mobile communication signal. The communication processor calculates the reception strength of the wireless signal received by each of the built-in antennas or each of the antennas. Each of the antenna switching circuits is electrically coupled to one of the built-in antennas or one of the antennas according to a control signal. The control processor correspondingly outputs the control signal according to the reception strength of the wireless signal received by the built-in antenna and the antenna.

The present disclosure describes apparatuses and methods of performance-based antenna selection for user devices. In some aspects, a user device includes a transceiver having a first receiver, as well as second and third receivers. The transceiver is coupled to a first antenna to enable communication via the first antenna and the second receiver is coupled to the second antenna to enable reception via the second antenna. The third receiver is coupled to a third antenna to enable monitoring of performance of the third antenna. Based on a comparison of respective performance of the first antenna and the third antenna, the first antenna or third antenna is coupled the transceiver to enable subsequent communication. By monitoring and comparing respective performance of the antennas before antenna switching is implemented, a better-performing antenna of the two antennas can be selected for coupling to the transceiver without impacting communication performance.
