Abstract: Embodiments of the present invention provide a method for determining a transmission rate supported by a data stream, user equipment, and a base station. The method includes: determining, by user equipment UE, a first index corresponding to an average transmission rate supported by a channel between the UE and the base station; determining, by the UE, a second index corresponding to a difference between an instantaneous transmission rate supported by a data stream on the channel and an average transmission rate supported by the data stream on the channel; sending, by the UE, the first index to the base station; and sending, by the UE, the second index to the base station. According to the embodiments of the present invention, the instantaneous transmission rate supported by the data stream on the channel can be relatively accurately fed back to the base station, thereby improving channel resource utilization.

Abstract: Embodiments of the present application disclose a visible light-based communication method, a related device, and a related system. A first VLC device is configured to send a reporting indication message to a coordinator when a VPAN ID conflict occurs on a VPAN. The reporting indication message includes VPAN ID information detected by the first VLC device. A coordinator device is configured to receive the reporting indication message sent by the first VLC device. A coordinator device is configured to select a new VPAN ID based on the VPAN ID information to resolve the VPAN ID conflict effectively.
