Abstract
(EN)
Aspects of beam specific scrambling of reference and data signals are disclosed. In an example, a user equipment (UE) receives a plurality of beams from a base station (404) and determines payloads of a first control signal of a first beam of the plurality of beams and a second control signal of a second beam of the plurality of beams are a same payload (406). The UE also compares signal quality characteristics of the first control signal the second control signal when the payloads are the same payload (408) and selects a better quality beam from the first beam and the second beam for decoding a data signal of the better quality beam in response to the comparison (410). The UE also decodes the data signal of the better quality beam (416).

L'invention concerne des aspects de brouillage spécifique au faisceau de signaux de référence et de données. Dans un exemple, un équipement d'utilisateur (UE) reçoit une pluralité de faisceaux en provenance d'une station de base (404) et détermine que des charges utiles d'un premier signal de commande d'un premier faisceau de la pluralité de faisceaux et d'un deuxième signal de commande d'un deuxième faisceau de la pluralité de faisceaux sont une même charge utile (406). L'UE compare également des caractéristiques de qualité de signal du premier signal de commande et du deuxième signal de commande lorsque les charges utiles sont la même charge utile (408) et sélectionne un faisceau de meilleure qualité parmi le premier faisceau et le deuxième faisceau pour décoder un signal de données du faisceau de meilleure qualité en réponse à la comparaison (410). L'UE décode également le signal de données du faisceau de meilleure qualité (416).
