Various methods and systems for efficiently performing the blind decoding of downlink signals are described. Several forms of arranging possible CCE combinations are examined and investigated. Based on PDCCH size estimation/information, CCE concatenations that are most likely (of limited sets) can be arrived at. Tree-based concatenations are also devised using largest CCE ordering to align smaller CCE sizes to similar boundaries. By such ordering, the search space for all possible CCE ordering and sizes can be reduced to an efficient tree. Set mapping between possible CCE/REs are also described using a first set to secondary and tertiary sets. Various other ordering and sorting schemes are also detailed that enable a blind decode of a PDCCH channel to be efficiently performed.

L'invention porte sur divers procédés et systèmes pour effectuer efficacement le décodage aveugle de signaux de liaison descendante. Plusieurs formes d'arrangements de possibles combinaisons d'éléments de canal de commande (CCE) sont examinées et étudiées. Sur la base d'estimation/informations de taille PDCCH, des concaténations de CCE qui sont les plus probables (d'ensembles limités) peuvent être obtenues. Des concaténations à base d'arbre sont également conçues en utilisant un classement de CCE les plus grands pour aligner des tailles de CCE plus petites sur des frontières similaires. Par un tel classement, l'espace de recherche pour tous les ordres et tailles de CCE possibles peut être réduit à un arbre efficace. Un mappage d'ensemble entre lnposelstartCCElnposelend/RE possibles est également décrit utilisant un premier ensemble vers des ensembles secondaire et tertiaire. Divers autres schémas de classement et de tri sont également détaillés qui permettent d'effectuer efficacement un décodage aveugle d'un canal PDCCH.
