The embodiment of the invention provides a visible light communication spatial modulation method based on a reflecting surface. The technical problem that the visible light communication spatial modulation capability is poor can be solved. The method comprises the following steps: determining an activation reflection group of a reflection surface according to a channel gain of a first optical signal emitted by an emitter; the emitter sends the first optical signal to the activation reflection group; the activation reflection group receives the first optical signal and sends the first optical signal carrying the first data to the receiver; the light reflected by each reflective array element can reach at most one receiving unit. And according to the channel gain of the first optical signal transmitted by the transmitter, determining an activation reflection group in the reflection groups with different activation probabilities so as to adapt to changing channel conditions.
