Title (EN) METHOD AND APPARATUS FOR PERFORMING DEVICE-TO-DEVICE COOPERATIVE COMMUNICATION IN WIRELESS ACCESS SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR RÉALISER UNE COMMUNICATION COOPÉRATIVE DE DISPOSITIF À DISPOSITIF DANS UN SYSTÈME D'ACCÈS SANS FIL
(KO) 무선 접속 시스템에서 단말 간 협력적 통신을 수행하기 위한 방법 및 장치
Abstract: front page image
(EN)The present invention relates to a method for performing a device-to-device cooperative transmission (D2D CT) using a multi-carrier in a wireless access system, including the steps of: enabling a source device to perform a network entry process with a base station using a primary carrier; enabling the source device to receive control information related to a dedicated carrier used for D2D CT from the base station through the primary carrier; and enabling the source device to transmit an uplink signal to a collaborative device using the dedicated carrier.
(FR)L'invention concerne un procédé pour réaliser une transmission coopérative de dispositif à dispositif (D2D CT) à l'aide d'une multiporteuse dans un système d'accès sans fil, comprenant les étapes suivantes : activation d'un dispositif source pour réaliser un processus d'entrée de réseau avec une station de base à l'aide d'une porteuse primaire; activation du dispositif source pour recevoir des informations de commande relatives à une porteuse dédiée utilisée pour une D2D CT provenant de la station de base grâce à la porteuse primaire; et activation du dispositif source pour transmettre un signal de liaison montante à un dispositif collaboratif à l'aide de la porteuse dédiée.
(KO)본 명세서는 무선 접속 시스템에서 멀티 캐리어를 이용하여 단말 간 협력적 전송(Device-To-Device Cooperative Transmission:D2D CT)을 수행하기 위한 방법에 있어서, 소스(source) 단말이 프라이머리 캐리어(primary carrier)를 이용하여 기지국과 네트워크 엔트리(network entry) 절차를 수행하는 단계; 상기 소스 단말이 상기 기지국으로부터 단말 간 협력적 전송에 사용되는 전용 캐리어(dedicated carrier)와 관련된 정보를 포함하는 제어 정보를 상기 프라이머리 캐리어를 통해 수신하는 단계; 및 상기 소스 단말이 상기 전용 캐리어를 이용하여 협력 단말로 상향링크 신호를 전송하는 단계를 포함하여 이루어지는 것을 특징으로 한다.
