Summary:The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data transmission rates than previous 4th generation (4G) communication systems such as long term evolution (LTE). An operation method of a base station according to various embodiments of the present disclosure includes: a process for determining at least one sub-carrier for allocating a phase tracking reference signal (PTRS); a process for transmitting information about the allocation of the PTRS to a terminal; and a process for transmitting the PTRS to the terminal through the at least one sub-carrier on the basis of the information. The device and method according to various embodiments of the present disclosure can control interference of the PTRS due to adjacent base stations by the base station determining the sub-carrier for allocating the PTRS and providing the information about the allocation of the PTRS to the terminal, and allows the estimation performance for the PTRS to be improved. La présente invention concerne un système de communication de 5e génération (5G) ou pré-5G permettant de prendre en charge des débits d'émission de données supérieurs à ceux des systèmes de communication précédents de 4e génération (4G) tel que LTE (évolution à long terme). Un procédé de fonctionnement d'une station de base selon divers modes de réalisation de la présente invention comprend : un processus permettant de déterminer au moins une sous-porteuse pour attribuer un signal de référence de suivi de phase (PTRS); un processus permettant de transmettre des informations concernant l'attribution du PTRS à un terminal; et un processus permettant de transmettre le PTRS au terminal par l'intermédiaire de la ou des sous-porteuses en fonction des informations. Le dispositif et le procédé selon divers modes de réalisation de la présente invention peuvent commander les interférences du PTRS causées par des stations de base adjacentes en déterminant, par la station de base, la sous-porteuse pour attribuer le PTRS et en fournissant les informations concernant l'attribution du PTRS au terminal, et permettent d'améliorer la performance d'estimation du PTRS. 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 기지국의 동작 방법은, PTRS(phase tracking reference signal)의 할당을 위한 적어도 하나의 서브캐리어(sub-carrier)를 결정하는 과정과, 상기 PTRS의 할당에 관한 정보를 단말로 송신하는 과정과, 상기 정보에 기반하여, 상기 적어도 하나의 서브캐리어를 통해 상기 PTRS를 상기 단말로 송신하는 과정을 포함한다. 본 개시의 다양한 실시 예들에 따른 장치 및 방법은, 기지국이 PTRS(phase tracking reference signal)의 할당을 위한 서브캐리어를 결정하고, PTRS의 할당에 관한 정보를 단말에 제공함으로써, 인접 기지국들로부터 초래되는 PTRS의 간섭을 제어할 수 있고, PTRS에 대한 추정 성능을 향상시킬 수 있게 한다.
