Example Embodiment
[0041] In the wireless communication transmission process of the multi-cell system, when there are too many obstacles between the user terminal and the base station, the signal strength declines too much, resulting in inefficient wireless communication transmission, and there are problems such as small coverage and serious interference. To this end, the present application provides a wireless communication method based on a smart reflective surface. The method adds a smart reflective surface composed of metamaterials near the user terminal. The smart reflective surface is a kind of low-cost metamaterial reflective elements composed of Reflect array, which can superimpose certain parameters such as phase shift and amplitude on the incident signal, so that the reflected signal and the direct signal can be coherently superimposed or suppressed at the receiving end of the user terminal, which has the advantages of easy deployment, low cost and light weight. In this application, by ...
