Title
(EN) SYNCHRONIZATION SIGNAL MEASUREMENT FOR BEAM DETECTION
(FR) MESURE DE SIGNAL DE SYNCHRONISATION POUR DÉTECTION DE FAISCEAU
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a measurement procedure for beam detection within an existing cell. The UE perform a search procedure for a first synchronization signal block (SSB) to detect a first beam of a base station. The UE may determine a first timing offset for the first SSB based on the search procedure. The UE may estimate a second timing offset for a second SSB from the base station based on the first timing offset. The UE may perform a measurement procedure for the second SSB to detect a second beam of the base station based on the second timing offset. The UE may prune fake beams based on synchronization signals used for the measurement procedure.

L’invention concerne des procédés, des systèmes et des dispositifs pour les communications sans fil. Un équipement d'utilisateur (UE) peut utiliser une procédure de mesure pour la détection de faisceau dans une cellule existante. L'UE effectue une procédure de recherche pour un premier bloc de signal de synchronisation (SSB) afin de détecter un premier faisceau d'une station de base. L'UE peut déterminer un premier décalage de synchronisation pour le premier SSB sur la base de la procédure de recherche. L'UE peut estimer un second décalage de synchronisation pour un second SSB à partir de la station de base sur la base du premier décalage de synchronisation. L'UE peut effectuer une procédure de mesure pour le second SSB afin de détecter un second faisceau de la station de base sur la base du second décalage de synchronisation. L'UE peut élaguer des faux faisceaux sur la base de signaux de synchronisation utilisés pour la procédure de mesure.
