Abstract
(EN) The present specification provides a method for transmitting or receiving a signal in a wireless communication system using an auto encoder. More particularly, the method performed by a receiving terminal comprises the steps of: receiving a first weight of a transmitting terminal encoder neural network from a transmitting terminal; learning the first weight and a second weight of a receiving terminal encoder neural network on the basis of a gradient descent method; transmitting update weight information updated for the first weight to the transmitting terminal on the basis of the learning; and receiving, from the transmitting terminal, a signal to which the update weight information is applied.
(FR) La présente spécification concerne un procédé d'émission ou de réception d'un signal avec un codeur automatique dans un système de communication sans fil. Plus spécifiquement, le procédé mis en œuvre par un terminal de réception comprend les étapes consistant à : recevoir un premier poids d'un réseau neuronal de codeur de terminal d'émission à partir d'un terminal d'émission ; apprendre le premier poids et un second poids d'un réseau neuronal de codeur de terminal de réception sur la base d'un procédé de descente de gradient ; transmettre des informations de poids de mise à jour actualisées pour le premier poids au terminal d'émission sur la base de l'apprentissage ; et recevoir, en provenance du terminal d'émission, un signal auquel les informations de poids mises à jour sont appliquées.
(KO) 본 명세서는 오토 인코더를 이용하는 무선 통신 시스템에서 신호를 송수신하기 위한 방법을 제공한다. 보다 구체적으로, 수신단에 의해 수행되는 상기 방법은 송신단 인코더 뉴럴넷의 제 1 가중치를 송신단으로부터 수신하는 단계; 상기 제 1 가중치와 수신단 인코더 뉴럴넷의 제 2 가중치를 경사 하강 방법에 기초하여 학습하는 단계; 상기 학습에 기초하여 상기 제 1 가중치에 대해 업데이트된 업데이트 가중치 정보를 상기 송신단으로 전송하는 단계; 및 상기 업데이트 가중치 정보가 적용된 신호를 상기 송신단으로부터 수신하는 단계를 포함하는 것을 특징으로 한다.
