Abstract
Embodiments of the present application disclose a method and terminal device for data transmission. The method is applied to a vehicle-to-everything system, and comprises: a terminal device in a first protocol layer determining, according to service information of data to be sent, a transmission mechanism for transmitting the data to be sent. The method and terminal device in the embodiments of the present application enhance data transmission capabilities.
Claims15
A method for data transmission, applied to an Internet of vehicles system, and comprising:
- determining at a first protocol layer, by a terminal device, a digital modulation mechanism for transmitting data to be sent, according to service information of the data to be sent,
- wherein the service information comprises at least one piece of information of the following information:
- version information, a fully qualified domain name (FQDN), or layer-2 address information;
- acquiring at a second protocol layer, by the terminal device, the service information;
- and
- sending at the second protocol layer, by the terminal device, the service information to the first protocol layer,
- wherein when the service information is version information, acquiring at the second protocol layer, by the terminal device, the service information of the data to be sent comprises:
- determining at the second protocol layer, by the terminal device, the version information of the data to be sent according to at least one piece of information of the following information:
- an internet protocol (IP) address, a service type, a service requirement, a FQDN, layer-2 address information, proximity-based service (ProSe) per-packet priority (PPPP) information, or ProSe per-packet reliability (PPPR),
- wherein the version information is used for indicating a protocol version for a service corresponding to the data to be sent.
