Title (EN) SYSTEM AND METHOD FOR INITIALIZATION OF A SCRAMBLING SEQUENCE FOR A DOWNLINK REFERENCE SIGNAL
(FR) SYSTÈME ET PROCÉDÉ D'INITIALISATION D'UNE SÉQUENCE DE BROUILLAGE POUR UN SIGNAL DE RÉFÉRENCE DE LIAISON DESCENDANTE
Abstract:
(EN) A system and method for initialing a scrambling sequence for a downlink reference signal in a Long Term Evolution-Advanced (LTE-A) system. The system and method include initializing at the start of a radio frame, a scrambling sequence generator that initializes a seed of a scrambling sequence for downlink cell-specific reference signals for the LTE-A component carriers. The initialization seed is based on the component carrier ID. The system and method can transmit the reference signal in filler bands located between at least two component carriers in the LTE-A system.
(FR) La présente invention concerne un système et un procédé pour initialiser une séquence de brouillage pour un signal de référence de liaison descendante dans un système LTE-A (Long Term Evolution-Advanced). Le système et le procédé consistent à initialiser, au démarrage d'une trame radio, un générateur de séquence de brouillage qui initialise un germe d'une séquence de brouillage pour des signaux de référence de liaison descendante spécifiques à la cellule pour les porteuses composantes LTE-A. Le germe d'initialisation est basé sur l'identificateur de la porteuse composante. Le système et le procédé peuvent transmettre le signal de référence dans des bandes d'éléments de remplissage situées entre au moins deux porteuses composantes dans le système LTE-A.
