Abstract

Des modes de réalisation de la présente invention concernent un procédé de brouillage de canal et un dispositif terminal, ce qui permet d'assurer que différentes séquences de brouillage sont utilisées pour des canaux transmis entre un dispositif terminal et différentes cellules, de réduire l'interférence mutuelle entre ces canaux, et d'améliorer les performances d'une transmission coopérative multicellulaire. Le procédé de brouillage de canal se délroule comme suit: un dispositif terminal détermine une valeur d'initialisation d'une séquence de brouillage d'un premier canal selon une identité de cellule portée par une première SSB, la première SSB étant utilisée pour obtenir un faisceau de transmission ou un faisceau de réception du premier canal; le dispositif terminal génère une interférence de brouillage du premier canal en fonction de la valeur d'initialisation de la séquence de brouillage.
