Title (EN) TECHNIQUES FOR TIMING CONTROL WITH FILTERING IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING-BASED SYSTEMS
(FR) TECHNIQUES DE COMMANDE DE SYNCHRONISATION AVEC FILTRAGE DANS DES SYSTÈMES BASÉS SUR UN MULTIPLEXAGE PAR RÉPARTITION ORTHOGONALE DE LA FRÉQUENCE
Abstract:
(EN) Various aspects described herein relate to techniques for timing control with filtering in orthogonal frequency division multiplexing (OFDM)-based wireless communications systems. In an aspect, the method includes determining whether time-domain filtering or frequency-domain filtering is used for a transmission signal waveform, and identifying a time delay based on a determination that the time-domain filtering is used for the transmission signal waveform. The method further includes applying a timing correction based on the identified time delay. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.
(FR) Divers aspects décrits dans la présente description concernent des techniques de commande de synchronisation avec filtrage dans des systèmes de communication sans fil basés sur un multiplexage par répartition orthogonale de la fréquence (OFDM). Selon un aspect, le procédé consiste à déterminer si un filtrage de domaine temporel ou un filtrage de domaine fréquentiel est utilisé pour une forme d'onde de signal de transmission, et à identifier un retard temporel sur la base d'une détermination selon laquelle le filtrage de domaine temporel est utilisé pour la forme d'onde de signal de transmission. Le procédé consiste en outre à appliquer une correction de synchronisation sur la base du retard temporel identifié. Les techniques décrites dans la présente description peuvent s'appliquer à différentes technologies de communication, notamment la technologie de communication de 5ème génération (5G) nouvelle radio (NR).
