- the modulation and coding scheme of the road safety information may be predetermined, such that the source vehicle SV does not need to additionally notify the target vehicle DV of the modulation and coding scheme at each broadcast, thereby facilitating the terminal of the target vehicle DV.
- Demodulation/decoding road Safety information and can also save the overhead of control information.
- the modulation coding method may not be included in the control information transmitted in the third step.
- the predetermined fixed group index and LCG ID can be used to some extent by the base station to identify the SL BSR related to the high priority close-up service, thereby enabling the base station to preferentially configure the communication resources for the terminal after receiving the SL BSR.
- the base station A reports the received road safety information and the location information of the source vehicle SV to the controller in step S820, and broadcasts a paging message to all the vehicle terminals belonging to the operator within its coverage in step S830, indicating that the road is triggered.
- Security Information Broadcast (only the paging message is sent to the target vehicle DV A in FIG. 8 is schematically shown).
- Input/output interface 905 is further coupled to bus 904.
- the input/output interface 905 is connected to an input unit 906 formed by a keyboard, a mouse, a microphone, or the like; an output unit 907 formed of a display, a speaker, or the like; a storage unit 908 formed of a hard disk, a nonvolatile memory, or the like;
- a communication unit 909 formed of a network interface card (such as a local area network (LAN) card, a modem, etc.); and a drive 910 that drives the removable medium 911 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory.
- LAN local area network
- the one or more processors are further configured to: control to establish time synchronization with the source device in accordance with a global synchronization signal source.
- the one or more processors are further configured to: determine a priority of the road event based on the information related to a road event; and determine the transmission of the synchronization information according to the priority A delivery period, wherein the higher the priority, the shorter the determined transmission period.
- the node device establishes time synchronization with the source device according to a global synchronization signal source.
- the one or more processors are further configured to: generate a first request message to send to the base station, the first request message to request the base station to allocate a resource for transmitting a second request message; and generate Sending the second request message to the base station, where the second request message is used to request the base station to allocate a resource for sending the service information, where the control information is used for the at least one target
- the device notifies the resource used to send the service information.
- the one or more processors are further configured to simultaneously allocate resources for transmitting the second request message and resources for transmitting the service information in response to the first request message by the base station In the case, a second request message of a specific format is generated.
