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, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention relates to a method and device for decoding data by a base station in a wireless communication system, and the method of the present invention comprises the steps of: transmitting, by a base station, phase tracking reference signal (PTRS) allocation information, which includes PTRS port information and orthogonal cover code (OCC) information, to a terminal; receiving, from the terminal, a demodulation reference signal (DMRS) and a PTRS to which an OCC depending on the OCC information has been applied, so as to estimate phase noise; and compensating the phase noise to decode data received from the terminal.

Abstract: The present disclosure relates to a 5G or a pre-5G communication system for supporting a higher data rate beyond 4G communication systems such as LTE. A signal transmitting method of an apparatus according to an embodiment of the present disclosure may include: confirming a location of a control signal for a first communication system when a transmission band of the first communication system and a transmission band of a second communication system overlap each other; puncturing a signal for the second communication system at the confirmed location of the control signal for the first communication system; and transmitting the punctured signal for the second communication system.
