Title: D2D DISCOVERY METHOD, DEVICE, AND TERMINAL FOR USE IN VEHICULAR COMMUNICATION
Abstract:
Provided are a D2D discovery method, device, and terminal for use in vehicular communication. The D2D discovery method for use in vehicular communication is applicable in the terminal and comprises: acquiring a transmission performance requirement satisfied by a service type corresponding to a vehicular communication service; when the vehicular communication service is determined, on the basis of the transmission performance requirement, as having a latency limit, executing a preregistration process to a network-side entity, and/or employing a pre-allocated transmission resource scheduling mechanism, and/or preacquiring identifier mapping information of the network-side entity, thus reducing interactions with the network-side entity when executing a D2D discovery process. The technical solution of the present invention allows the terminal, when executing the D2D discovery process, to reduce as much as possible interactions with the network-side entity, thus effectively reducing latency to the D2D discovery process, and implementing support for V2X short latency transmission.
