Abstract
(EN)
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method for operating a base station in a wireless communication system, including: determining an interference coordination information format according to uplink resource allocation of a terminal; and determining the interference coordination information according to the determined interference coordination information format, and transmitting the interference coordination information between neighboring base stations. According to the present disclosure, it is possible to implement inter-cell interference coordination better.

La présente invention concerne un système de communication 5G ou de pré-5ème génération conçu pour prendre en charge des débits de données supérieurs dépassant un système de communication (4G) de 4ème génération telle qu'une technologie d'évolution à long terme (LTE). La présente invention porte sur un procédé permettant de faire fonctionner une station de base dans un système de communication sans fil, consistant : à déterminer un format d'informations de coordination de brouillages selon une attribution de ressources de liaison montante d'un terminal ; et à déterminer des informations de coordination des brouillages selon le format d'informations de coordination de brouillages déterminé, et à transmettre les informations de coordination des brouillages entre des stations de base voisines. Selon la présente invention, il est possible d'améliorer la mise en œuvre d'une coordination des brouillages entre cellules.
