Embodiments of the present disclosure relate to automatic antenna beam alignment. A method comprises determining first position-related information indicating a first location and a first orientation of a first communication device. The first communication device comprises a plurality of antenna sectors configured for generating respective directional beams. The method also comprises receiving, from a second communication device, second position-related information indicating a second location and a second orientation of the second communication device. The method also further comprises selecting a subset of the plurality of antenna sectors based on the first and the second position-related information; and causing the first communication device to perform beamforming training with the second communication device using the selected subset of antenna sectors. A decreased number of antenna sectors are scanned during the beamforming training, which can reduce the time overhead and facilitate the devices to find the best beam efficiently.

A method is performed by an electronic device that includes antenna modules AM1 and AM2. The method includes: while transmitting or receiving through AM1, receiving a specified wireless signal through AM1 and AM2; identifying a first signal quality for the specified wireless signal of AM1 and a second signal quality for the specified wireless signal of AM2; and in response to determining that a difference between the first signal quality and the second signal quality is within a specified signal quality range and that a rank of a wireless channel through which the specified wireless signal is received is two or more, selecting an antenna module to transmit or receive a wireless signal, from among AM1 and AM2, based on first channel information about AM1 and second channel information about AM2. The method includes transmitting or receiving the wireless signal using the selected antenna module.

The wireless communication device (200) according to the present disclosure includes the control unit (260). The control unit (260) acquires the temperatures of a plurality of antennas (2110) having different directivities. The control unit (260) acquires information regarding the communication quality of the plurality of antennas (2110). In a case where the temperature of the antenna which is being used for communication is equal to or higher than the second temperature threshold which is lower than the first temperature threshold for determining whether or not to stop using the antenna (2110), the control unit (260) switches the antenna which is being used to an antenna selected on the basis of the communication quality among the antennas whose temperatures are lower than the second temperature threshold.

Aspects of this disclosure provide techniques for detecting and recovering from beam-failure events. In some embodiments, motion sensor information generated by motion sensors on a UE is used to detect, predict, and/or recover from a beam failure event that results, or would otherwise result, from movement of the UE. The motion sensor information may be used to adjust a current beam direction used by the UE to transmit or receive a signal, or to determine a recommendation for adjusting a current beam direction of the base station. The motion sensor information may be generated by any sensor that detects a movement of the UE, such as a gyroscope, an accelerometer, a magnetometer, a global positioning system (GPS) sensor, a global navigation satellite system (GNSS) sensor, or any other device that detects a change in position/orientation of the UE.

Disclosed are an electromagnetic interference control method, an electronic device and a non-transitory computer-readable storage medium. The method includes detecting whether a camera of the electronic device is activated, responsive to detecting that the electronic device receives a voice communication service; detecting whether electromagnetic interference occurs between the camera and a radio frequency system of the electronic device, responsive to detecting that the camera is activated; if yes, responsive to determining that the currently activated primary antenna is a first antenna, sending a first preset instruction to a modem by an application processor; and receiving the first preset instruction by the modem for switching the activated antenna from the first antenna to a second antenna and fix. Based on the method, the interference of a radio frequency system on a mobile phone camera is reduced, camera screen crash or jam is reduced, and imaging quality is improved.
