Abstract

La présente invention se rapporte à des procédés adaptés pour atténuer des interférences sur la base d'une configuration de tranche de temps asymétrique sur la liaison montante (UL)/sur la liaison descendante (DL). Lesdites interférences se produisent au cours d'une transmission de nœud B évolué (eNB) à eNB. Les eNB agresseur/victime sont identifiés en utilisant des moyens de mesure ou des moyens statiques/semi-statiques. Cela permet à son tour d'identifier l'ensemble de cellules dont la réception sur la liaison UL peut être impactée par la transmission sur la liaison DL de l'eNB agresseur. Des mécanismes de coordination d'interférences entre les cellules (ICIC) sont élargis de sorte à négocier et à gérer une programmation qui atténue de façon intelligente des interférences qui se produisent dans les tranches de temps qui entrent en collision.
