Title (EN) METHOD FOR DETERMINING A MODULATION AND CODING SCHEME IN A BROADBAND WIRELESS ACCESS SYSTEM

(KO) 광대역 무선 접속 시스템에서 변조 및 부호화 기법 결정 방법
Abstract: front page image
(EN)The present invention relates to a broadband wireless access system, and more particularly, to a method in which a terminal determines a modulation and coding scheme (MCS) of uplink allocation information received from a base station under a condition such as that of a random access process in which both the terminal and the base station do not know each other's channel state. According to one exemplary embodiment of the present invention, a method in which the terminal transmits specific data to the base station under the condition in which the base station does not know the channel state of the terminal, comprises: a step of receiving, from the base station, uplink allocation information for indicating an uplink resource for transmitting the specific data; a step of determining a modulation and coding scheme (MCS) to be applied to the specific data using information on the size and allocation size of the specific data; and a step of transmitting, to the base station via the uplink resource, the specific data to which the determined MCS is applied. Here, the MCS is desirably the lowest MCS determined by the base station.
(FR)La présente invention concerne un système d'accès sans fil large bande, et plus particulièrement un procédé dans lequel un terminal détermine un schéma de modulation et de codage (MCS) d'informations d'attribution de liaison montante reçues à partir d'une station de base sous une condition telle qu'un procédé d'accès aléatoire dans lequel le terminal comme la station de base ne connaissent pas leur état de canal mutuel. Selon un mode de réalisation de l'invention, un procédé dans lequel le terminal transmet des données spécifiques à la station de base sous la condition selon laquelle la station de base ne connaît pas l'état de canal du terminal, comprend : une étape qui consiste à recevoir, à partir de la station de base, des informations d'attribution de liaison montante pour indiquer une ressource de liaison montante pour transmettre les données spécifiques; une étape qui consiste à déterminer un schéma de modulation et de codage (MCS) à appliquer aux données spécifiques au moyen d'informations portant sur la taille et l'attribution des données spécifiques; et une étape qui consiste à transmettre, à la station de base par l'intermédiaire de la ressource de liaison montante, les données spécifiques auxquelles le MCS déterminé est appliqué. En l'occurrence, le MCS est de préférence le MCS le plus bas déterminé par la station de base.
(KO)본 발명은 광대역 무선 접속 시스템에 관한 것으로, 보다 상세히는 임의 접속(random access) 절차와 같이 단말과 기지국이 상호간의 채널 상태를 알지 못하는 상황에서 단말이 기지국으로부터 수신되는 상향링크 할당 정보의 변조 및 부호화 기법을 판단하는 방법에 관한 것이다. 본 발명의 일 실시형태에 따른 기지국이 단말의 채널 상태를 알지 못하는 상황에서 상기 단말이 상기 기지국에 특정 데이터를 전송하는 방법은, 상기 특정 데이터를 전송하기 위한 상향링크 자원을 지시하는 상향링크 할당 정보를 상기 기지국으로부터 수신하는 단계; 상기 특정 데이터의 크기 및 할당 크기(allocation size) 정보를 이용하여 상기 특정 데이터에 적용될 변조 및 부호화 기법(MCS: Modulation and Coding Scheme)을 판단하는 단계; 및 상기 상향링크 자원을 통하여 상기 판단한 MCS를 적용한 상기 특정 데이터를 상기 기지국으로 전송하는 단계를 포함할 수 있다. 여기서 상기 MCS는 상기 기지국이 결정한 최저 MCS인 것이 바람직하다.
