Title (EN) ENHANCED BROADCAST CHANNEL FOR PRIMARY SYSTEM INFORMATION ACQUISITION IN OFDM/OFDMA SYSTEMS
(FR) CANAL DE DIFFUSION AMÉLIORÉ POUR L'ACQUISITION D'INFORMATIONS SYSTÈME PRIMAIRES DANS DES SYSTÈMES OFDM/OFDMA
Abstract: front page image
(EN)New enhanced physical broadcast channel (EPBCH) based on UE-specific reference signals (DMRS) for MIB and SIB transmission is proposed. The overall design consideration for EPBCH can be summarized as follows: support different values of frequency reuse factor, support different cell coverage sizes, maximized diversity gain in open-loop operation such as transmit diversity and frequency diversity,minimized overhead, and minimized UE complexity.
(FR)L'invention concerne un nouveau canal de diffusion physique amélioré (EPBCH) basé sur des signaux de référence spécifiques à un UE (DMRS) pour des transmission MIB et SIB. La considération de conception générale d'un EPBCH peut être résumée comme suit : prise en charge de différentes valeurs de facteur de réutilisation de fréquence; prise en charge de différentes dimensions de couverture de cellule; optimisation du gain en diversité lors d'un fonctionnement en boucle ouverte (diversité en transmission et en fréquence); réduction du surdébit; et simplification de l'UE.
