Abstract

La présente invention concerne un appareil et un procédé de traitement de signal basé sur une séquence. Le procédé consiste : à déterminer une séquence qui est utilisée pour satisfaire un PUSCH envoyant un signal, la séquence étant une séquence {xn} qui comprend N éléments, xn indiquant les éléments dans la séquence {xn}, et la séquence déterminée {xn} est une séquence qui satisfait une condition prédéfinie; et à générer ensuite un premier signal et à l'envoyer. En utilisant la séquence déterminée ci-dessus, une meilleure planéité de domaine de fréquence de séquence peut être maintenue lorsqu'un PUSCH est utilisé pour envoyer un signal, et une valeur de PAPR inférieure et une corrélation croisée inférieure entre des séquences peuvent également être conservées, ce qui permet de satisfaire un environnement d'application de communication consistant à utiliser le PUSCH pour envoyer un signal. En particulier, un système NR ou un scénario similaire à NR est satisfait.
