Abstract: This application provides a method for determining a transport block size and a communication apparatus, which may be used in systems such as vehicle-to-everything, V2X, and V2V. A receive-end terminal device and a transmit-end terminal device may determine a quantity of encoded symbols based on a symbol length used for sidelink communication in a time unit and an scaling factor, and may further determine a transport block size of a data channel based on the quantity of encoded symbols. Therefore, for all slots used for sidelink communication, a same quantity of encoded symbols can be determined, and a same transport block size can be further determined.

Abstract: A communication method and related terminal apparatus are provided, which are applicable to the fields such as V2X, intelligent driving, assisted driving, connected vehicles, internet of vehicles, and the like. A first terminal apparatus determines, based on identifier information and resource configuration information, a resource for sending an energy-saving signal, so that a destination of the energy-saving signal, namely, a second terminal apparatus, may learn of a source of the energy-saving signal. The second terminal apparatus determines, based on the identifier information and the resource configuration information, a resource for receiving the energy-saving signal, so that the second terminal apparatus may receive the energy-saving signal on a specified resource. The second terminal apparatus wakes up or goes to sleep based on the energy-saving signal, to reduce power consumption.

Abstract: A method and an electronic device for authentication is provided. When a user performs a touch operation on an icon of a first application, a biological feature of the user is directly collected without displaying an authentication screen, the collected biological feature is compared with a biological feature bound to the first application, and when a comparison result indicates that the collected biological feature matches the biological feature bound to the first application, the first application is logged in to. Based on the foregoing process, authentication can be implemented through only one interaction between the user and the electronic device, so that user operations are simplified.
