Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-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.

Abstract: The present specification relates to a precoding-related information transmitting or receiving method and apparatus. A precoder-related information receiving method by a user equipment according to an embodiment of the present specification comprises the steps of: transmitting an aperiodic channel state information (CSI) report; receiving a rank indicator and a first precoder indicator from a base station; acquiring a second precoder indicator included in the most recent aperiodic CSI report which corresponds to the rank indicator in the aperiodic CSI reports transmitted by the user equipment; and receiving a signal using the first precoder indicator and the second precoder indicator. According to an embodiment of the present specification, precoding-related information can be effectively transmitted or received.
