1. A method for data transmission, applied to an Internet of vehicles system, and comprising:
acquiring, by a terminal device, version information of data to be sent; and
determining, by the terminal device, a digital modulation mechanism for transmitting the data to be sent, according to the version information of the data to be sent,
wherein, acquiring, by the terminal device, the version information of the data to be sent comprises:
determining, 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: a service identifier, an internet protocol (IP) address, a service type, a service requirement, a fully qualified domain name (FQDN), layer-2 address information, proximity-based service (ProSe) per-packet priority (PPPP) information, or ProSe per-packet reliability (PPPR) information,
wherein the version information is used for indicating a protocol version for a service corresponding to the data to be sent,
wherein determining, by the terminal device, the digital modulation mechanism for transmitting the data to be sent, according to the version information of the data to be sent comprises:
determining, by the terminal device, the digital modulation mechanism for transmitting the data to be sent, according to the protocol version for the service indicated by the version information.
