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), receives a first OFDM symbol and a first CP prepended to the first OFDM symbol. The apparatus processes the first OFDM symbol according to a first CP length of the first CP based at least in part on whether the first OFDM symbol includes a first information type.[French]
Divers aspects de la présente divulgation 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), reçoit un premier symbole OFDM et un premier CP ajouté au premier symbole OFDM. L'appareil traite le premier symbole OFDM en fonction d'une première longueur de CP du premier CP sur la base, au moins en partie, du fait que le premier symbole OFDM comprend, ou non, un premier type d'informations.
