Abstract: Embodiments of the present invention provide a method, a device, and a communications system for performing data communication by using an unlicensed spectrum. In an embodiment, a base station determines to use an unlicensed spectrum to perform data communication, and sends mode request information to a terminal. The terminal receives the mode request message sent by the base station and determines, according to a preset configuration table, whether to use the unlicensed spectrum to perform data communication. When determining to use the unlicensed spectrum to perform data communication, the terminal sends a mode acknowledgement message to the base station. The base station receives the mode acknowledgement information sent by the terminal, and the terminal performs data communication in a first unlicensed frequency band with the base station.

Abstract: The present invention provides a data transmission method and apparatus. In the data transmission method, a terminal searches for a visible light network and determines a target visible light network from found visible light networks; then obtains a communication parameter of the target visible light network, establishes, according to the obtained communication parameter corresponding to the target visible light network, a downlink VLC link between the terminal and a VLC device corresponding to the target visible light network, and receives data sent by the VLC device by using the downlink VLC link. Therefore, a part of a traffic intensive downlink service is forwarded to the terminal by using the downlink VLC link, and a transmission rate of an entire wireless communications network is increased.
