Abstract: A data transmission method, an apparatus, and a system are provided to optimize a data transmission manner in an intelligent cockpit scenario, and relate to the short-range communications field. In this application, a first communications apparatus may indicate, to a second communications apparatus, a first service and a first resource corresponding to the first service. When the second communications apparatus needs to send first data of the first service, a media access control layer of the second communications apparatus may transparently transmit the data of the first service. Correspondingly, when the first communications apparatus receives the first data of the first service, a media access control layer of the first communications apparatus transparently transmits the first data.

Abstract: A method for indicating, obtaining, and sending automated driving information includes: starting, by a first vehicle, an automated driving function application, or receiving, by a first vehicle, an instruction used to instruct the first vehicle to start an automated driving function application; and indicating, by the first vehicle by using first indication information, that a driving status of the first vehicle is an automated driving state. A vehicle having an automated driving function sends the automated driving information to a surrounding traffic participant, especially to a surrounding vehicle or a pedestrian, so that the surrounding traffic participant identifies the automated driving vehicle, to improve traffic safety of an entire road.

Abstract: The present invention discloses a data packet transmission method. A terminal device receives uplink scheduling resource configuration information sent by a base station; the terminal device determines a data transmission priority corresponding to each of N logical channels; the terminal device loads data on M logical channels in the N logical channels into a media access control protocol data unit (MAC PDU) based on the data transmission priority corresponding to each of the N logical channels; and the terminal device sends the MAC PDU to the base station on the uplink scheduling resource by using the physical communication characteristic of the uplink scheduling resource. According to the embodiments of the present invention, transmission of data on a logical channel with a high priority is ensured, and a waste of resources is avoided, thereby matching a resource with a service to the utmost.

Abstract: Example data transmission methods and devices are described. In one example method, data and attribute information of the data are received at a transmitting end from at least one data source. The original data is segmented based on the attribute information to obtain a plurality of data sections. A respective check code for each of the plurality of data sections is calculated based on each of the plurality of data sections. A plurality of coded blocks are sent. The plurality of coded blocks are received at a receiving end. A check is performed on data sections included in the plurality of coded blocks by using check codes included in the plurality of coded blocks. At least a data section that is successful in the check is provided for a user.

Abstract: This application relates to the intelligent cockpit field and provides a communication method and apparatus, to reduce communication interference between devices. In this application, if priorities of one or more second devices are lower than a priority of a first device, the first device sends second information to the one or more second devices, where the second information includes a communication resource allocated by the first device to the one or more second devices and the priority of the first device. When the priorities of the one or more second devices are lower than the priority of the first device, the first device may allocate the communication resource to the one or more second devices. This can avoid communication interference between different communication domains that is caused by a conflict between communication resources, and improve communication performance of the devices.
