Abstract: A first terminal obtains a first transmission resource that is sent by an access network device and that is used by the first terminal to send data on a sidelink, where the sidelink is a wireless communication link between the first terminal and a second terminal, and the first transmission resource is a resource of an unlicensed spectrum. The first terminal performs a channel access procedure on the unlicensed spectrum. The first terminal sends first information to the access network device when the first terminal determines that a failure occurs in the channel access procedure performed on the unlicensed spectrum, where the first information is used to request to allocate a second transmission resource to the sidelink of the unlicensed spectrum.

Abstract: This application provides an information processing method and apparatus. In the information processing method provided in this application, a transmitter uses, as a reference data packet, an Ethernet data packet generated based on data collected by a sensor at a historical moment, establishes corresponding data tables at a receiver and the transmitter, then differentiates a first Ethernet data packet generated based on data subsequently collected by the sensor from the reference data packet to obtain deviation information, compresses the deviation information by using a preset coding algorithm to obtain compressed information for transmission, and finally transmits, to the receiver, packet identification information corresponding to the reference data packet, second identification information of a first sensor, and the compressed information, to compress the first Ethernet data packet.

Abstract: A communication method for data transmission in the internet of vehicles V2X and a related device. The method includes a first terminal device that receives first information from a first radio access network device, where the first information includes service information of a service of the first terminal device and a resource configuration mode on a sidelink, and there is a correspondence between the service information and the resource configuration mode on the sidelink. The first terminal device transmits, based on the correspondence, data corresponding to the service information on a sidelink transmission resource configured based on the resource configuration mode. The service information may be reliability information.
