Abstract

The present disclosure relates to a communication technology in which a 5G communication system supporting a higher data rate after a 4th Generation (4G) system is fused with an Internet of Things (IoT) technology, and a system therefor. The present disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, etc.) based on the 5th Generation (5G) communication technology and IoT-related technology. In addition, the present disclosure provides a method and apparatus for reducing power consumption of a user equipment (UE) in a wireless communication system.

Description

technical field [0001] The present disclosure relates to a channel estimation method and apparatus for an OFDM-based single-carrier system. Background technique [0002] In order to meet the increasing demands of wireless data traffic since the deployment of fourth generation (4G) communication systems, efforts have been made to develop improved fifth generation (5G) or quasi-5G communication systems. The 5G or quasi-5G communication system is also referred to as "Super 4G Network" or "Post Long Term Evolution LTE System". Therefore, 5G communication systems are considered to be implemented in higher frequency millimeter wave (mmWave) bands (eg, the 60GHz band) to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, large-scale antennas in 5G communication systems are discussed ...
