This disclosure relates to the coexistence of GNSS and satellite communications. Electronic devices can communicate with an NTN using an external clock from a non-terrestrial network (NTN). The electronic devices can determine the external clock used for communication with the NTN. The devices can receive indication of the external clock from a Global Navigation Satellite System (GNSS) or from jamming signals. Jamming signals can at least partially mask GNSS signals. Nearby devices may be using an external clock to transmit jamming signals to the NTN. Nearby devices can embed each frame cycle of the external clock into a predetermined pattern of silence periods or transmission gaps. The electronic devices can determine the relationship (e.g., duration offset) between the silence period in the predetermined pattern of silence periods and the frame boundaries of the frame cycle of the external clock. Therefore, the electronic devices can communicate with the NTN even though GNSS signals are masked.

The present invention relates to an apparatus and method for supporting vehicle-to-everything communication and a system including the same. A V2X communication apparatus, a system including the same, and a method are provided. The V2X communication apparatus includes a communication electronic control unit (ECU) that processes messages transmitted and received in a wired or wireless manner, and an application (AP) ECU that identifies messages transmitted and received by the communication ECU through an internal protocol of a vehicle and provides corresponding service information. The AP ECU is disposed as a system area separate from the communication ECU. The AP ECU and the communication ECU transmit and receive messages through Ethernet or a controller area network (CAN) communication that is an internal protocol of the vehicle.

The application discloses a device communication method and device based on UART communication protocol and electronic equipment, which is applied to communication between electronic equipment and peripheral equipment, the electronic equipment comprises a central processing unit and a UART interface, the peripheral equipment comprises a UART connector, the UART connector and the UART interface both have data receiving pins and data sending pins, a communication connection is established between the data transmission channel and the data receiving pins and the data sending pins of the UART connector, and the method comprises the following steps: configuring a data time-sharing round-robin transmission strategy, so that the peripheral equipment and the electronic equipment both alternately send data according to a preset time length; when the peripheral equipment sends data, the data is transmitted to the data receiving pins of the electronic equipment through the data transmission channel; when the electronic equipment sends data, the data is transmitted to the data receiving pins of the peripheral equipment through the data transmission channel; and based on the time-sharing round-robin transmission strategy, the peripheral equipment and the electronic equipment time-sharing alternately transmit data.

This invention discloses a near-field communication electronic device, a card reader, and a wake-up method thereof. In this method, the card reader periodically transmits a probe wave of fixed amplitude; after receiving the probe wave, the analog card modulates it with a pulse wave of varying amplitude and transmits it back to the card reader; the card reader detects the amplitude changes of multiple received signals and calculates the amplitude difference between adjacent signals; if the amplitude difference of multiple consecutive signals conforms to a preset regularity, a wake-up interrupt is triggered and communication is established. This invention significantly improves the card reader's detection sensitivity and anti-interference capability for analog cards by identifying the trend of amplitude changes, making it particularly suitable for wearable devices with limited antenna size.
