Method and device for data decoding by terminal in wireless communication system

Abstract

The present disclosure relates to a communication technique for converging IoT technology with 5G communication systems for supporting higher data transmission rates than 4G systems and to a system therefor. The present disclosure can be applied to intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The method for data decoding by a terminal in a wireless communication system according to the present disclosure comprises the steps of: receiving subframes on the basis of a configuration; obtaining at least one channel phase value on the basis of available subframes, which are configured to transmit identical downlink data, among the received subframes; correcting the other channel phase value(s) with any one of said at least one obtained channel phase value as a reference value; and decoding the downlink data by means of the reference value and the corrected channel phase value(s).
