Abstract
A wireless communication method using a large intelligent surface (LIS) is provided. The method includes transmitting preamble signals each with a different transmission time and transmission direction, receiving preamble signals through an LIS through which an incident radio wave is received and reflected and determining a reference angle of incidence for the preamble signals, receiving the preamble signals that are delivered through a multipath from the terminal, transmitting identification information of a preamble signal having the largest reception power among the received preamble signals to the LIS server, and when the preamble signals includes a preamble signal corresponding to the identification information received from the base station, controlling the LIS such that an angle of reflection at which a data service signal transmitted from the base station is reflected by the LIS corresponds to the reference angle of incidence determined for the preamble signal of the identification information.
