Abstract: A terminal synchronization method and a terminal relate to the communications field, where the terminal sends synchronization signals in a distributed manner by controlling a sequence for sending the synchronization signals such that terminals in a vehicle to vehicle communications system can have uniform timing. The method includes obtaining, by a terminal, a configurable transmission period for sending a first synchronization signal, and sending, by the terminal, the first synchronization signal based on the configurable transmission period.

Abstract: A network slice selection method, a radio access device, and a terminal, where the method includes obtaining, by a radio access network (RAN) device, network slice information, sending, by the RAN device, a first message to a terminal, where the first message includes the network slice information, receiving, by the RAN device, a first access request message from the terminal after the terminal selects, based on the network slice information, first attribute information of a first network slice to be accessed by the terminal, and selecting, by the RAN device based on the first attribute information of the first network slice, a second network slice to be accessed by the terminal. The method enables an operator to flexibly configure a network slice, and reduces a communication latency and signaling overheads in a process in which a terminal selects a network slice.

Abstract: A random access method and apparatus are provided. The random access method includes receiving, by a terminal, virtual cell information at a virtual frequency, where the virtual cell information includes information about at least one physical cell indicated by the virtual cell; determining, by the terminal according to the information about the at least one physical cell, a target physical cell to be pre-accessed; and accessing, by the terminal, the target physical cell using information about the target physical cell. According to embodiments of the present disclosure, information about a physical cell can be received and transmitted at a virtual frequency, such that an idle virtual frequency resource is fully utilized, and a latency is reduced.
