Description

Apparatus and method for controlling an antenna in a wireless communication system Various embodiments of the present disclosure relate to wireless communication systems, for example, to electronic devices or methods for controlling an antenna. Efforts are being made to develop improved 5G (5th generation) communication systems or pre-5G communication systems to meet the increasing demand for wireless data traffic following the commercialization of 4G (4th generation) communication systems. For this reason, 5G communication systems or pre-5G communication systems are referred to as Beyond 4G Network communication systems or Post-LTE systems. To achieve high data transmission rates, 5G communication systems are being considered for implementation in the mmWave band (e.g., the 60 GHz band). To mitigate path loss and increase the transmission distance of radio waves in the mmWave band, beamforming, massive MIMO, full Dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large-scale antenna technologies are being discussed for 5G communication systems. In addition, to improve the network of the system, technologies such as advanced small cell, advanced small cell, cloud radio access network (cloud RAN), ultra-dense network, Device to Device communication (D2D), wireless backhaul, mobile telecommunication, cooperative communication, Coordinated Multi-Points (CoMP), and interference cancellation are being developed in 5G communication systems. In addition, advanced coding modulation (ACM) methods such as FQAM (Hybrid Frequency Shift Keying and Quadrature Amplitude Modulation) and SWSC (Sliding Window Superposition Coding), as well as advanced access technologies such as FBMC (Filter Bank Multi Carrier), NOMA (Non Orthogonal Multiple Access), and SCMA (Sparse Code Multiple Access) are being developed in 5G systems. In 5G systems, massive multiple-input multiple-output (massive MIMO) systems, which utilize a large number of antennas in transmitters and receivers, are considered highly important and are being actively researched as one of the technologies that will play a significant role in future wireless communication systems. To obtain sufficient gain through massive MIMO systems, base stations require channel state information (CSI). Accordingly, various studies are underway to effectively acquire channel state information.
