Abstract: A vehicle-mounted device control method includes a digital certificate to perform security authentication between electronic control units (ECUs), and a function that is currently allowed to be accessed is determined based on a matching degree of certificate chains. The method comprises transmitting the digital certificate and an encrypted instruction between the ECUs, determining accessible functions based on the matching degree of certificate chains, and either starting, or failing to start, a function based on permission to access the function.

Abstract: The present disclosure relates to communication method and a communications apparatus. One example method includes determining, based on a receiving status of a first power saving signal, that a physical downlink control channel (PDCCH) is not detected within a first discontinuous reception (DRX) cycle; and performing, in a first time period within the first DRX cycle, radio resource management (RRM) measurement on a channel state information reference signal (CSI-RS) sent by a network device.

Abstract: Aspects of the present disclosure provide methods and apparatuses for protecting a reference signal (RS) and/or adjusting timing advance (TA) values to be used for timing synchronization between an apparatus (e.g. user equipment (UE))) and a device (e.g. transmit-and-receive point (TRP)) in a wireless network. The device operates in full-duplex (FD) mode and the apparatus operates in half-duplex (HD) or FD mode. In some embodiments, RSs transmitted in uplink and downlink directions are protected by puncturing one or more portions of time-frequency resources so that interference from other signals can be avoided or mitigated. The punctured portion of the time-frequency resources may be one or more symbols that together overlaps with a symbol at which the RS is to be received or sent. The device may send information indicating the portion to puncture using a higher-layer signaling, a dynamic signaling, or a preconfiguration by the network.

Abstract: A display circuit includes a plurality of current source branches and a plurality of pixel branches. Each current source branch includes a first transistor and a control circuit. Each pixel branch includes a second transistor, a pulse width control switch transistor, and a pixel unit that are connected in series. The turned-on first transistor and the turned-on second transistor form a current mirror structure. In the current mirror structure, there is a proportional relationship between a current flowing through each of the plurality of first transistors and a current flowing through the turned-on second transistor. Whether each first transistor is turned on is controlled through the control circuit, to adjust a value of the current flowing through each pixel unit through the second transistor.
