Title
(EN) METHOD AND DEVICE FOR TRANSMITTING/RECEIVING SIGNALS RELATED TO CHANGE OF TX/RX CAPABILITY IN FDR SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF D'ÉMISSION/RÉCEPTION DE SIGNAUX ASSOCIÉS À UN CHANGEMENT DE CAPACITÉ DE TX/RX DANS UN SYSTÈME FDR
(KO) FDR 시스템에서 TX/RX CAPABILITY의 변경과 관련된 신호 송수신 방법 및 장치
Abstract
(EN) One embodiment of the present invention relates to a method whereby a second node transmits/receives signals in a full duplex radio (FDR) system, the method for transmitting/receiving signals in an FDR system comprising steps in which: the second node transmits a signal to a first node as the second node receives a signal from the first node; the second node transmits Tx/Rx capability information to a third node if the transmission of the signal to the first node is completed during the reception of the signal from the first node; and the second node receives a signal from the third node after transmitting the Tx/Rx capability information.
(FR) Un mode de réalisation de la présente invention concerne un procédé par lequel un deuxième nœud émet/reçoit des signaux dans un système radio en duplex intégral (FDR), le procédé d'émission/réception de signaux dans un système FDR comprenant des étapes durant lesquelles : le deuxième nœud émet un signal vers un premier nœud lorsque le deuxième nœud reçoit un signal provenant du premier nœud; le deuxième nœud émet des informations de capacité d'émission/réception (TX/RX) vers un troisième nœud si l'émission du signal vers le premier nœud est achevée pendant la réception du signal provenant du premier nœud; et le deuxième nœud reçoit un signal provenant du troisième nœud après l'émission des informations de capacité TX/RX.
(KO) 본 발명의 일 실시예는, FDR(Full Duplex Radio) 시스템에서 제2 노드가 신호를 송수신하는 방법에 있어서, 제2 노드가 제1 노드로부터 신호를 수신하면서 상기 제1 노드로 신호를 전송하는 단계; 제2 노드가 상기 제1 노드로부터 신호 수신 중 상기 제1 노드로 신호 전송이 완료된 경우, Tx/Rx capability 정보를 제3 노드로 전송하는 단계; 및 제2 노드가 상기 Tx/Rx capability 정보 전송 후 상기 제3 노드로부터 신호를 수신하는 단계를 포함하는, FDR 시스템에서 신호 송수신 방법이다.
