(FR) CONFIGURATION DE SIGNAL DE RÉFÉRENCE À ÉTAPES MULTIPLES ET DÉTECTION À DES FINS DE GESTION D'INTERFÉRENCE
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A core network may organize a set of base stations into a set of cell groups, each cell group including one or more base stations, the cell groups being organized based on potential of each base station to cause interference, by downlink transmission, to reception of uplink transmissions at remote base stations. The core network may identify cell group identifications for each cell group and configure the set of base stations with respective cell group identifications so that signals transmitted from individual base stations of each cell group include the respective cell group identification, and so that remote base stations whose uplink transmissions are interfered with can identify the cell group of base stations causing the interference. The number of base stations in a cell group may be iteratively reduced based on identifying the interference.

L’invention concerne des procédés, des systèmes et des dispositifs destinés à des communications sans fil. Un réseau central peut organiser un ensemble de stations de base en un ensemble de groupes de cellules, chaque groupe de cellules comprenant une ou plusieurs stations de base, les groupes de cellules étant organisés sur la base du potentiel de chaque station de base permettant de provoquer des interférences, par transmission en liaison descendante, à la réception de transmissions en liaison montante au niveau de stations de base à distance. Le réseau central peut identifier des identifications de groupe de cellules correspondant à chaque groupe de cellules et configurer l'ensemble de stations de base à l'aide des identifications de groupes de cellules respectives de telle sorte que des signaux transmis des stations de base individuelles de chaque groupe de cellules comprennent l'identification respective de groupe de cellules, et de telle sorte que des stations de base distantes dont les transmissions en liaison montante sont interférées peuvent identifier le groupe de cellules des stations de base provoquant l'interférence. Le nombre de stations de base dans un groupe de cellules peut être réduit de manière itérative sur la base de l'identification de l'interférence.
