Title (EN) METHOD FOR PERFORMING HARQ BY USING POLAR CODE HAVING RANDOM LENGTH
(FR) PROCÉDÉ POUR RÉALISER UNE REQUÊTE DE RÉPÉTITION AUTOMATIQUE HYBRIDE (HARQ) PAR UTILISATION D’UN CODE POLAIRE AYANT UNE LONGUEUR ALÉATOIRE

Abstract:
(EN) The present specification provides a method for performing a physical layer security-based hybrid automatic repeat request (HARQ). The method comprises the steps of: generating a first code comprising information bits for forming data to be transmitted, and non-information bits which are unrelated to the data to be transmitted; generating a second code, having a length which differs from that of the first code, by puncturing the first code; determining locations of the information bits and non-information bits within the second code such that a variance of mutual information for each of the information bits and the non-information bits is maximized; and performing the HARQ by using the second code in which the locations of the information bits and the non-information bits are determined.
(FR) La présente invention concerne un procédé pour réaliser une requête de répétition automatique hybride (HARQ) basée sur une sécurité de couche physique. Le procédé comprend les étapes consistant à : générer un premier code comprenant des bits d’informations pour former des données à transmettre, et des bits de non-informations qui sont non associés aux données à transmettre ; générer un second code, ayant une longueur qui diffère de celle du premier code, par perforation du premier code ; déterminer des emplacements des bits d’informations et des bits de non-informations à l’intérieur du second code de telle sorte qu’une variance d’informations mutuelles pour chacun des bits d’informations et des bits de non-informations est rendue maximale ; et réaliser la HARQ par utilisation du second code dans lequel les emplacements des bits d’informations et des bits de non-informations sont déterminés.
(KO) 본 명세서의 일 개시는 물리 계층 보안(physical layer security)에 기초한 HARQ(Hybrid Automatic Repeat reQuest) 수행 방법을 제공한다. 상기 방법은 전송하고자 하는 데이터를 구성하는 정보 비트 및 상기 전송하고자 하는 데이터와 관련이 없는 비정보 비트를 포함하는 제1 코드를 생성하는 단계, 상기 제1 코드를 펑처링(puncturing)하여 상기 제1 코드와 길이가 상이한 제2 코드를 생성하는 단계, 상기 정보 비트 및 비정보 비트 각각에 대한 상호 정보량(mutual information)의 분산(variance)이 최대가 되도록, 상기 제2 코드 내에서 상기 정보 비트 및 비정보 비트의 위치를 결정하는 단계, 및 상기 정보 비트 및 비정보 비트의 위치가 결정된 제2 코드를 이용하여 HARQ를 수행하는 단계를 포함할 수 있다.
