Abstract
The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4-Generation (4G) communication system such as long-term evolution (LTE). An operation method of a base station in a wireless communication system may include obtaining indicators corresponding to a precoder, precoding a signal using the precoder, and transmitting the precoded signal to the terminal. The precoder may include elements defined by a phase value, an exponential value, or a sign, determined by combining variables based on the indicators. The precoder may be determined by searching a first memory storing coefficients for combining the variables corresponding to an antenna port and a layer, a second memory storing a size of a sine wave and cosine wave corresponding to the phase value, or a third memory storing a sign corresponding to a combination of an antenna port or a layer.
