Abstract: A beam training method and a related device are disclosed. The method includes: sending, by a first communications device, sidelink control information (SCI) to a second communications device, where the SCI is used to instruct the first communications device to send at least one channel state information-reference signal (CSI-RS) to the second communications device; and sending, by the first communications device, the at least one CSI-RS to the second communications device based on the SCI, where the at least one CSI-RS is used by the second communications device to determine that a beam corresponding to a CSI-RS with highest signal strength in the at least one CSI-RS is a beam for communication between the second communications device and the first communications device. The CSI-RS used for beam training is dynamically sent based on the instruction of the SCI.

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.

Abstract: A random access method, user equipment (UE), a base station, and a random access system, are provided to address relatively long service delay. In various embodiments, after downlink synchronization with a cell is obtained, UE can determine a preamble sequence of the UE in the cell, where the UE has not obtained uplink synchronization with the cell. The UE can then obtain service data and generate a scrambling code, and scramble the service data based on the scrambling code to obtain scrambled service data. The UE can then configure, based on a predetermined resource mapping relationship, time-frequency resources respectively occupied by the preamble sequence and the scrambled service data. The UE then sends on the configured time-frequency resources, the preamble sequence and the scrambled service data to a base station the cell belongs to and receives random access response sent by the base station based on the preamble sequence.
