Abstract

La présente invention concerne un codage de synchronisation secondaire utilisant un code de brouillage lié à canal de synchronisation primaire (P-SCH). Des codes de synchronisation secondaire brouillés (SSC) peuvent être alloués à de multiples stations de base d'un réseau d'accès radio (RAN). Par exemple, des codes de brouillage basés sur un code de synchronisation primaire (PSC) peuvent être créés à partir d'une pluralité de séquences M générées à partir d'une expression polynomiale commune. En outre, un livre de codage SSC est proposé, lequel sélectionne des paires de séquences d'une matrice de séquences pour générer des SSC. La sélection peut être basée sur des caractéristiques de transmission de SSC résultant, fournissant une interférence réduite dans des déploiements mobiles panifiés, semi-planifiés et/ou non planifiés.
