The present document relates to a method for transmitting and receiving a signal by a user equipment in a wireless communication system, and discloses the method for transmitting and receiving a signal, comprising the steps of: receiving a first reference signal from a base station; receiving a second reference signal from the base station; measuring power of each of the received first reference signal and the received second reference signal; and comparing the sizes of the measured power of the first reference signal and the measured power of the second reference signal, wherein the first reference signal is received in a half-duplex (HD) transmission mode, the second reference signal is received in a full-duplex (FD) transmission mode, and an FD gain value of the FD transmission mode is changed on the basis of a result of the comparing.

The method includes: obtaining a first operating frequency of the camera and a second operating frequency of the antenna; determining the second operating frequency is interfered; in response to the second operating frequency being interfered, obtaining a target frame rate range; determining an operating frequency of the camera corresponding to each frame rate in the target frame rate range; obtaining an operating frequency list; determining at least one third operating frequency from the operating frequency list; and selecting one third operating frequency from the at least one third operating frequency as a first target operating frequency; determining a first target frame rate; operating the camera at the first target operating frequency; and performing the video function based on the first target frame rate.

A method for electromagnetic interference control and related devices are provided. The method includes the following. Electromagnetic interference between a Wi-Fi module and a MIPI of a display of the electronic device is detected in response to detecting a request for screen-projection to a target screen-projection device. In response to the detected electromagnetic interference, the display is turned off, and screen-projection to the target screen-projection device is performed, where the first prompt message indicates that the electronic device is turning off the display and performing screen-projection to the target screen-projection device.

A method for mitigating interference across analog signal lines includes receiving a digital data stream including a plurality of discrete signal patterns configured to drive a plurality of different analog signal lines. An edge buffer for each analog signal line is populated with edge data representing pulse edges of upcoming signal patterns set to drive the analog signal line. A target buffer for a target signal line is populated with target data representing a target signal pattern. Edge buffers corresponding to potentially interfering analog signal lines are searched to identify potentially interfering pulse edges. A set of potentially interfering pulse edges are selected for interference mitigation, and the target signal pattern is modified to perform preemptive interference mitigation based at least in part on the selected pulse edges.

The disclosure describes techniques to filter unwanted noise from feedback signals of an electrical machine. An electrical machine may receive AC power from an inverter and circuitry in the inverter may cause noise on the AC power signals to the electrical machine. The noise may couple to sensors for the electrical machine and cause noise in the sensor output signals. The sensor output signals may provide feedback for a closed loop control system for the electrical machine and noise may impact the closed loop operation. Also, the noise in the feedback signals may cause electromagnetic compatibility (EMC) issues, either by direct radiated emissions or by coupling to other circuits in the vehicle wiring harness as the feedback signals travel from the electrical machine. The techniques of this disclosure may include filter circuitry located near or inside the electrical machine that filters out the unwanted noise in the feedback signals.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.
