Original Abstract Submitted
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.
