Abstract

Des modes de réalisation de la présente invention concernent un procédé d'indication de signal de référence, un procédé de détermination de signal de référence et un dispositif. Le procédé d'indication de signal de référence comprend les étapes suivantes : un dispositif de réseau génère un message d'indication de signal de référence comprenant des informations de code d'embrouillage qui est utilisé pour indiquer des informations utilisées pour embrouiller le signal de référence ; le dispositif de réseau envoie le message d'indication de signal de référence. Selon les modes de réalisation de la présente invention, le dispositif de réseau peut embrouiller le signal de référence sur la base de multiples types d'informations ; par rapport à l'état de la technique dans lequel un signal de référence peut être embrouillé uniquement sur la base d'un identifiant de cellule ou d'un identifiant de cellule virtuelle, le dispositif de réseau peut configurer le signal de référence de manière plus flexible.
