摘要： A short-range communication method and apparatus are applied to the field of short-range communication, particularly related to scenarios such as smart driving, smart manufacturing, and can establish time-frequency synchronization between nodes in an entire network. The method includes: A first node receives at least one piece of node information from at least one node; and the first node controls the first node to establish time-frequency synchronization with a second node that is in the at least one node and that belongs to a second synchronization area, where node information from the second node includes synchronization information of the second synchronization area, and the synchronization information indicates at least one of a node identifier, a synchronization status, or a synchronization direction between nodes in the second synchronization area. This solution may be further used to improve an autonomous driving or advanced driver assistance system ADAS capability.

摘要： A data transmission method may include a first control apparatus sending first indication information to a second control apparatus. The first indication information is used to indicate to measure link quality between the second control apparatus and at least one terminal device. The second control apparatus generates first data. The second control apparatus sends the first data to the at least one terminal device based on the first indication information. The first data measure the link quality between the second control apparatus and the at least one terminal device.

摘要： This application provides a data transmission method and an apparatus, and relates to the field of communications technologies, and in particular, to short-range communication, for example, a cockpit domain. This improves transmission efficiency and reduces system overheads and a latency. The method includes: A second node receives first configuration information from a first node. The first configuration information is used to configure a first time-frequency resource. The second node obtains first information corresponding to a first logical channel, where the first information is used to indicate whether segmentation of a data packet on the first logical channel is allowed, the first logical channel corresponds to a second time-frequency resource, and the second time-frequency resource is included in the first time-frequency resource. The second node sends first data to the first node by using the first time-frequency resource. This application is applied to data transmission.
