METHOD FOR CONTROLLING WIRELESS COMMUNICATION IN BEAMFORMING-BASED CELLULAR SYSTEM

摘要

The present disclosure relates to a communication scheme and system for converging a 5^th generation (5G) communication system for supporting a data rate higher than that of a 4^th generation (4G) system with an internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, retails, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. The present disclosure relates to a radio network technology for use in a beamforming-based cellular system. A method for compensating phase noise by a user equipment (UE) is provided. The method comprises receiving, from a base station, association information between at least one phase tracking reference signal (PTRS) port and at least one demodulation reference signal (DMRS) port, identifying phase noise between the UE and the base station based on the association information, and compensating for the phase noise based on the result of the identification.
