Abstract:
(EN) The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than 4th generation (4G) communication systems such as long term evolution (LTE). In a wireless communication system, a transmission apparatus comprises at least one antenna port for transmitting/receiving a signal, an analogue filter for selecting the frequency of the signal, and a voltage standing wave ratio (VSWR) detection unit for measuring the VSWR of the antenna port, wherein the VSWR detection unit is configured to detect both a forward signal and a reverse signal for an input terminal of the analogue filter, to determine the respective power values of a forward signal and a reverse signal for an output terminal of the analogue filter by applying characteristic parameters of the analogue filter to the detected forward signal and reverse signal, and to determine the VSWR of the antenna port on the basis of the respective power values of the forward signal and the reverse signal for the output terminal of the analogue filter.
(FR) La présente invention concerne un système de communication de 5e génération (5G) ou pré-5G permettant de prendre en charge un débit d'émission de données supérieur à celui d’un système de communication de 4e génération (4G) tel qu'un système d'évolution à long terme (LTE). Dans un système de communication sans fil, un appareil d'émission comprend au moins un port d'antenne permettant d'émettre/recevoir un signal, un filtre analogique permettant de sélectionner la fréquence du signal, et une unité de détection de rapport d'onde stationnaire de tension (VSWR) permettant de mesurer le VSWR du port d'antenne, l'unité de détection de VSWR étant conçue pour détecter à la fois un signal vers l'avant et un signal vers l'arrière pour une borne d'entrée du filtre analogique, pour déterminer les valeurs de puissance respectives d'un signal vers l'avant et d'un signal vers l'arrière pour une borne de sortie du filtre analogique par l'application de paramètres caractéristiques du filtre analogique au signal vers l'avant et au signal vers l'arrière détectés, et pour déterminer le VSWR du port d'antenne en fonction des valeurs de puissance respectives du signal vers l'avant et du signal vers l'arrière pour la borne de sortie du filtre analogique.
(KO) 본 개시는 LTE(Long Term Evolution)와 같은 4G(4th generation) 통신 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G(5th generation) 또는 pre-5G 통신 시스템에 관련된 것이다. 무선 통신 시스템에서 송신 장치는 신호를 송수신하는 적어도 하나의 안테나 포트와, 상기 신호의 주파수 선택 기능을 수행하는 아날로그 필터와, 상기 안테나 포트에 대한 정재파비(voltage standing wave ratio, VSWR)를 측정하는 VSWR 검출부를 포함하고, 상기 VSWR 검출부는 상기 아날로그 필터의 입력단에 대한 순방향 신호 및 역방향 신호 각각을 검출하고, 아날로그 필터의 특성 파라미터들을 상기 검출된 순방향 신호 및 역방향 신호에 적용함으로써 상기 아날로그 필터의 출력단에 대한 순방향 신호 및 역방향 신호 각각의 전력 값을 결정하고, 상기 아날로그 필터의 출력단에 대한 순방향 신호 및 역방향 신호 각각의 전력 값에 기반하여 상기 안테나 포트에 대한 VSWR을 결정하도록 구성된다.
