Zusammenfassung:The present disclosure relates to a radio frequency integrated circuit (RFIC), a massive multiple-input multiple-output (MIMO) unit (MMU) apparatus including the RFIC, and an operating method thereof, and the RFIC according to an embodiment of the present disclosure comprises: a digital front end unit that up-converts a transmitting signal and down-converts a receiving signal; a fast Fourier transform (FFT)/inverse FFT (iFFT) unit that converts the transmitting signal from a frequency domain to a time domain and converts the receiving signal from a time domain to a frequency domain; a cyclic prefix (CP) unit that adds CP to the transmitting signal and removes CP from the receiving signal; and an interface unit that performs communication with a signal processing unit. La présente divulgation concerne un circuit intégré radiofréquence (RFIC), un appareil d'unité à entrées multiples et sorties multiples (MIMO) massives (MMU) comprenant le RFIC, et son procédé de fonctionnement, et le RFIC selon un mode de réalisation de la présente divulgation comprend : une unité d'extrémité avant numérique qui convertit vers le haut un signal de transmission et convertit vers le bas un signal de réception ; une unité de transformée de Fourier rapide (FFT)/FFT inverse (iFFT) qui convertit le signal de transmission d'un domaine fréquentiel à un domaine temporel et convertit le signal de réception d'un domaine temporel à un domaine fréquentiel ; une unité de préfixe cyclique (CP) qui ajoute un CP au signal de transmission et élimine le CP du signal de réception ; et une unité d'interface qui effectue une communication avec une unité de traitement de signal. 본 개시는 RFIC(radio frequency integrated circuit) 및 RFIC를 포함하는 MMU(massive MIMO(multiple-input multiple-output) unit) 장치와 그 동작 방법에 관한 것으로, 본 개시의 일 실시예에 따른 RFIC(radio frequency integrated circuit)은, 송신 신호를 상향 변환(up-convert)하고, 수신 신호를 하향 변환(down-convert)하는 디지털 프론트 엔드부(digital front end unit), 상기 송신 신호를 주파수 도메인에서 시간 도메인으로 변환하고, 상기 수신 신호를 시간 도메인에서 주파수 도메인으로 변환하는 FFT(fast Fourier transform)/iFFT(inverse FFT)부(FFT/iFFT unit), 상기 송신 신호에 대해서 CP(cyclic prefix)를 추가하고 상기 수신 신호에 대해서 CP를 제거하는 CP부(CP unit) 및 신호 처리부(signal processing unit)와 통신을 수행하는 인터페이스부(interface unit)를 포함한다.
