Abstract:
(EN) Disclosed is a service terminal. A service terminal according to one embodiment of the present invention comprises: a generating unit for generating an orthogonal frequency division multiplexing (OFDM) symbol by performing an inverse fast Fourier transform (IFFT) on one or more subcarriers on the basis of set input signals; a modulating unit for modulating the orthogonal frequency division multiplexing symbol; and a transmitting unit for transmitting, to a wireless terminal, the modulated orthogonal frequency division multiplexing symbol in order to switch the wireless terminal operating in a sleep mode to a normal mode, wherein the input signals consist of a combination of one or more input values which minimize a sum of squares of the magnitude of the orthogonal frequency division multiplexing symbol.
(FR) L'invention concerne un terminal de service. Un terminal de service selon un mode de réalisation de la présente invention comprend : une unité de génération conçue pour générer un symbole de multiplexage par répartition orthogonale de la fréquence (OFDM) au moyen de la réalisation d'une transformée de Fourier rapide inverse (IFFT) sur une ou plusieurs sous-porteuses sur la base de signaux d'entrée définis ; une unité de modulation conçue pour moduler le symbole de multiplexage par répartition orthogonale de la fréquence ; et une unité de transmission conçue pour transmettre, à un terminal sans fil, le symbole de multiplexage par répartition orthogonale de la fréquence modulé afin de commuter le terminal sans fil fonctionnant en mode sommeil vers un mode normal, les signaux d'entrée étant constitués d'une combinaison d'une ou de plusieurs valeurs d'entrée qui réduisent au minimum une somme des carrés de l'amplitude du symbole de multiplexage par répartition orthogonale de la fréquence.
(KO) 서비스 단말이 개시된다. 본 발명의 일 실시예에 따른 서비스 단말은 설정된 입력 신호들을 기반으로 하나 이상의 부반송파를 역 고속 퓨리에 변환(Inverse Fast Fourier Transform, IFFT)하여 직교 주파수 분할 다중(Orthogonal Frequency Division Multiplex, OFDM) 심볼을 생성하는 생성부; 상기 직교 주파수 분할 다중 심볼을 변조하는 변조부; 및 슬립 모드(sleep mode)로 동작하고 있는 무선 단말을 정상 모드(normal mode)로 전환시키기 위해 변조된 상기 직교 주파수 분할 다중 심볼을 상기 무선 단말로 전송하는 전송부를 포함하며, 상기 입력 신호들은, 상기 직교 주파수 분할 다중 심볼의 크기에 대한 제곱 합(Sum of Squares)을 최소화시키는 하나 이상의 입력 값의 조합으로 이루어진다.
