Summary:The present disclosure relates to a 5G (5th generation) or pre-5G communication system for supporting a higher data transmission rate beyond a 4G (4th generation) communication system such as long-term evolution (LTE). A operation method of a base station in a wireless communication system, according to various embodiments of the present disclosure, comprises the steps of: generating at least one compressed symbol on the basis of modulation compression; transmitting, to another base station, control information including location indication information for indicating a location of a subcarrier to which a first subcarrier signal is transmitted in a physical resource block (PRB) to which the at least one compressed symbol is mapped, and power indication information for indicating the transmission power of the first subcarrier signal; and transmitting the at least one compressed symbol to the another base station. Therefore, the transmission capacity can be optimized, and efficient modulation compression is possible. La présente invention concerne un système de communication 5G (de 5ème génération) ou pré-5G permettant de prendre en charge un débit de données supérieur à celui d'un système de communication 4G (4ème génération), tel qu'un système d'évolution à long terme (LTE). Selon divers modes de réalisation de la présente invention, un procédé de fonctionnement d'une station de base dans un système de communication sans fil consiste : à générer au moins un symbole compressé en fonction d'une compression de modulation ; à transmettre, à une autre station de base, des informations de commande comprenant des informations d'indication d'emplacement permettant d'indiquer un emplacement d'une sous-porteuse à laquelle un premier signal de sous-porteuse est transmis dans un bloc de ressources physiques (PRB) auquel ledit symbole compressé est mappé, et des informations d'indication de puissance permettant d'indiquer la puissance de transmission du premier signal de sous-porteuse ; et à transmettre ledit symbole compressé à l'autre station de base. Ainsi, la capacité de transmission peut être optimisée et une compression de modulation efficace est possible. 본 개시는 LTE(Long Term Evolution)와 같은 4G(4th generation) 통신 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G(5th generation) 또는 pre-5G 통신 시스템에 관련된 것이다. 본 개시의 다양한 실시 예들에 따른 무선 통신 시스템에서 기지국의 동작 방법은, 변조 압축에 기반하여 적어도 하나의 압축 심볼을 생성하는 과정과, 상기 적어도 하나의 압축 심볼이 매핑된 PRB(physical resource block)에서 제1 서브캐리어 신호가 전송되는 서브캐리어의 위치를 지시하는 위치 지시 정보와, 상기 제1 서브캐리어 신호의 전송 전력을 지시하기 위한 전력 지시 정보를 포함하는 제어 정보를 다른 기지국으로 송신하는 과정과, 상기 적어도 하나의 압축 심볼을 상기 다른 기지국으로 송신하는 과정을 포함한다. 따라서, 전송 용량이 최적화될 수 있고, 효율적인 변조 압축이 가능하다.
