Embodiments of the present invention provide a wireless communication method, base station and system. The base station includes several LED lights and/or several VLC/IR receivers. The several LED lights are configured to send downlink signals in an OFDMA standard to a user terminal, and the several VLC/IR receivers are configured to receive uplink signals that are of an SC-FDMA standard and sent by the user terminal. The base station further includes a baseband signal processing unit configured to equate the several LED lights and/or the several VLC/IR receivers with radio remote units of an LTE mode to perform processing and resource management. The embodiments of the present invention are capable of reusing baseband signal processing and resource management manners in an existing LTE system, thereby simplifying resource management and baseband signal processing operations performed by the base station, and saving the base station resources.
