Abstract: The present disclosure provides a method of sending a vehicle-to-everything (V2X) service message. The method includes: determining, by a terminal device, a communication path for a V2X service, where the communication path is selected from at least two communication paths, the at least two communication paths include a first communication path and a second communication path, the first communication path is a communication path on which communication is performed using a PC5 interface, and the second communication path is a communication path on which communication is performed using a Uu interface; and sending, by the terminal device, a message of the V2X service by using the communication path. In the foregoing solution, the communication path can be selected from the at least two communication paths, to send the message of the V2X service. In this way, a communication path is flexibly selected for a V2X service.

Abstract: A communication method and apparatus are disclosed. According to the communication method, a first terminal determines a logical channel identifier (LCID) meeting a preset condition, where a first packet data convergence protocol (PDCP) entity of the first terminal is associated with two or more logical channels (LCHs); the first terminal receives a first data packet from a second terminal; and the first PDCP entity of the first terminal parses the first data packet based on the LCID. In this way, corresponding PDCP entities of the first terminal and the second terminal use consistent input parameters when executing security algorithms, thereby ensuring normal communication on a sidelink and improving communication reliability.
