Title (EN) METHOD FOR TRANSMITTING AND RECEIVING DATA THROUGH RELAY IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ D'ÉMISSION ET DE RÉCEPTION DE DONNÉES DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ

Abstract:
(EN) Disclosed are a method for transmitting and receiving data through a relay in a wireless communication system and an apparatus therefor, Specifically, a method by which a remote user equipment (remote UE) transmits and receives data with a network through a relay UE in a wireless communication system comprises the steps of: recognizing that small data to be transmitted to the network has been generated; performing a discovery procedure through the relay UE and a PC5 interface; and transmitting a PC5 message including the small data to the relay UE when it is confirmed in the discovery procedure that the relay UE has the ability to transmit the small data to the network, wherein when it is indicated that the relay UE supports the small data transmission procedure by a PC5 discovery message received from the relay UE in the discovery procedure, it can be determined that the relay UE has the ability to transmit the small data to the network.
(FR) L'invention concerne un procédé d'émission et de réception de données par l'intermédiaire d'un relais dans un système de communication sans fil et un appareil associé, et plus particulièrement, un procédé par lequel un équipement utilisateur distant (UE distant) émet et reçoit des données par un réseau par l'intermédiaire d'un UE relais dans un système de communication sans fil comprend les étapes consistant : à reconnaître que de petites données devant être émises au réseau ont été générées ; à effectuer une procédure de découverte par l'intermédiaire de l'UE relais et d'une interface PC5 ; et à émettre un message PC5 comprenant les petites données à l'UE relais lorsqu'il est confirmé dans la procédure de découverte que l'UE relais a la capacité de transmettre les petites données au réseau, lorsqu'il est indiqué que l'UE relais prend en charge la procédure d'émission de petites données par un message de découverte PC5 reçu de l'UE relais dans la procédure de découverte, il peut être déterminé que l'UE relais a la capacité de transmettre les petites données au réseau.
(KO) 무선 통신 시스템에서 릴레이를 통한 데이터 송수신 방법 및 이를 위한 장치가 개시된다. 구체적으로, 무선 통신 시스템에서 원격 사용자 장치(Remote UE: Remote User Equipment)가 릴레이 UE(Relay UE)를 통해 네트워크와 데이터를 송수신하는 방법에 있어서, 네트워크로 전송할 스몰 데이터(small data)가 발생하였음을 인지하는 단계, 상기 Relay UE와 PC5 인터페이스를 통해 디스커버리 절차를 수행하는 단계 및 상기 디스커버리 절차에서 상기 Relay UE가 상기 스몰 데이터를 네트워크로 전송할 수 있는 능력을 가졌음을 확인하면, 상기 Relay UE에게 상기 스몰 데이터를 포함하는 PC5 메시지를 전송하는 단계를 포함하고, 상기 디스커버리 절차 내에서 상기 Relay UE로부터 수신한 PC5 디스커버리 메시지에 의해 상기 Relay UE가 스몰 데이터 전송 절차를 지원한다고 지시되면, 상기 Relay UE가 상기 스몰 데이터를 네트워크로 전송할 수 있는 능력을 가졌다고 판단될 수 있다.
