Abstract[English]
Various aspects of the present disclosure relate to cyclic prefix (CP) for Orthogonal Frequency Division Multiplexing (OFDM) symbols. An apparatus, such as a user equipment (UE), one or more of receives or transmits a set of one or more OFDM symbols, each OFDM symbol of the set of one or more OFDM symbols including a corresponding CP. A length of the corresponding CP is based at least in part on at least a first subcarrier spacing configuration, and the set of one or more OFDM symbols is based at least in part on a second subcarrier spacing configuration different than the first subcarrier spacing configuration.[French]
Divers aspects de la présente invention concernent des préfixes cycliques (CP) pour des symboles de multiplexage par répartition orthogonale de la fréquence (OFDM). Un appareil, tel qu'un équipement utilisateur (UE), qui reçoit ou transmet un ensemble d'un ou plusieurs symboles OFDM, chaque symbole OFDM de l'ensemble d'un ou plusieurs symboles OFDM comprenant un CP correspondant. Une longueur du CP correspondant est basée au moins en partie sur au moins une première configuration d'espacement de sous-porteuses, et l'ensemble d'un ou plusieurs symboles OFDM est basé au moins en partie sur une deuxième configuration d'espacement de sous-porteuses différente de la première configuration d'espacement de sous-porteuses.
