US 10,952,259 B2 · Device and method for transmitting/receiving data in wireless communication system

Abstract

The present disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, and security and safety related services, on the basis of 5G communication s technologies and IoT-related technologies. To this end, a communication device may determine control information for a superposition transmission, and acquire selection sources in response to the determined control information. The communication device may transmit a preamble sequence on the basis of the acquired selection sources in a preamble transmission area according to the superposition transmission, and transmit data using the determined control information in a data superposition transmission area according to the superposition transmission.
