The user-centric architecture is the trend for constructing future networks. To improve user experience, visible light communication system adopts user-centric cooperative transmission technology, which breaks the traditional concept of network-centric. Generating user-centric cells for each user can make the best of network resources, which is of great significance in the 5G era with the design concept of small unit scenes. However, it is still in the initial stage, and the basic theories and key technologies need to be further studied. This paper expounds the new design concept, describes the characteristics and the forming process of user-centric virtual community centering on users, and introduces the key technologies of multi-user processing, channel estimation and network resource management combined with the unique features of visible light. This new mode of transmission can provide the user with the service of the network and improve the user’s peak rate and edge user performance.
