Abstract: This application relates to the field of intelligent transportation and intelligent vehicle technologies, and may be applied to a plurality of traffic scenarios, for example, a self-driving scenario. An example interaction method includes obtaining, by a first roadside device, first feature information of a traffic participant; and indicating, by a second roadside device, second feature information and a global identifier to the first roadside device. If the first feature information matches the second feature information, the first roadside device uses the global identifier to indicate the first feature information. A further interaction method includes configuring, by a server, a global identifier of a traffic participant based on feature information reported by a roadside device.

Abstract: A distributed learning method and apparatus for combining wireless communication with distributed learning to save resources, and improve performance of distributed learning in a wireless environment. A first node processes first data using a first data model to obtain first intermediate data. The first node sends the first intermediate data to a second node through a first channel. The first channel is updated based on error information of second intermediate data, information about the first channel, and the first intermediate data. The second intermediate data is a result of transmitting the first intermediate data to the second node through the first channel. The first channel is a channel between the first node and the second node.

Abstract: A first communication apparatus receives training data, and determines a first intermediate gradient based on the training data. The first intermediate gradient is used to update a parameter of a first neural network located in a second communication apparatus. The first communication apparatus maps the first intermediate gradient to an air interface resource to generate a first gradient signal, and sends the first gradient signal to the second communication apparatus. The first gradient signal includes one or more first gradient symbols, and each of the first gradient symbols is corresponding to one or more gradient values.
