13. A method for wireless communication using a large intelligent surface (LIS), the method comprising:
receiving, via the LIS, at least one preamble signal transmitted from a terminal, wherein each of the at least one preamble signal having a different transmission time and transmission direction;
determining a reference angle of incidence for each of the at least one preamble signal;
receiving, from a base station, identification information of a preamble signal having a largest reception power among the at least one received preamble signal, wherein the at least one preamble signal is transmitted by the terminal and received by the base station through a multipath; and
based on the at least one preamble signal including one 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 one preamble signal corresponding to the identification information.
