Abstract

L'invention propose des systèmes et des procédés d'une procédure de faisceau de sondage. Dans certains modes de réalisation, un procédé mis en œuvre par un équipement utilisateur (UE) pour évaluer des liaisons de paire de faisceaux candidates comprend : l'indication d'un support pour sonder un signal de référence (RS) de liaison montante (UL) pendant une signalisation de capacité; la détermination d'un filtre spatial pour une transmission UL-RS sur la base d'un ou de plusieurs signaux de référence de liaison descendante (DL) (DL-RS); la mise à jour de la relation spatiale d'un UL-RS; et la transmission d'UL-RS directement sans avoir besoin d'une mise à jour de relation spatiale explicite pour l'UL-RS à partir d'un nœud de réseau. De cette manière, certains modes de réalisation permettent au réseau d'évaluer des liaisons de paire de faisceaux candidates sur la base d'une transmission UL-RS d'un UE, sans qu'il soit nécessaire d'indiquer explicitement un filtre spatial que l'UE doit utiliser pour la transmission UL-RS. Certains modes de réalisation décrivent plusieurs solutions sur la manière d'effectuer les procédés avec un surdébit UL-RS réduit en laissant l'UE aider à déclencher la transmission UL-RS.
