An information transmission method, device and system

Abstract

The embodiment of the present application discloses an information transmission method, device, and system, which relate to vehicle-to-vehicle communication technology, V2X, smart cars, automatic driving, intelligent networked cars and other fields, and are used to simplify the above-mentioned information interaction process, save transmission resources, and improve information transmission efficiency. The method of the present application includes: the first communication device receives the first information sent by the second communication device, and the third information sent by the third communication device, wherein the first information and the third information are in the same time-frequency resource the first communication device generates second information according to the first information and the third information; the first communication device sends the second communication device to the second communication device and the third communication device. second information and first indication information, where the first indication information is used to indicate that the second information is generated by the first information and the third information.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an information transmission method, device and system. Background technique [0002] At present, in wireless communication technology, when two terminals need to perform data transmission, but there is no corresponding transmission interface between the above two terminals or the transmission distance is limited, the above two terminals cannot directly transmit data between the above two terminals, so , the data transmission between the above two terminals needs to be forwarded by the relay device to indirectly realize the indirect data transmission between the above two terminals. [0003] When the relay device performs data interaction for two terminals, the relay device needs to receive the signals sent by the above two terminals respectively, and forward the signals of the respective terminals to the opposite terminal respectively. For example, th...

AI Technical Summary

Problems solved by technology

[0004] In the above information interaction process, four steps are required to complete the information interaction between the first terminal and the second terminal. The information interaction process is relatively complicated, resulting in a long time-consuming information interaction and a waste of transmission resources.
