Abstract
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. The disclosure provides a codebook determination method of a terminal. The codebook determination method includes modulating input bits to generate a symbol vector using index information, determining a codebook based on information on subcarriers and information on modulation, determining a unitary matrix to be assigned to the terminal based on a codeword of the determined codebook, precoding the symbol vector based on the codebook and the unitary matrix, and transmitting the symbol vector to a base station on the subcarriers.
