Abstract
(EN)
In the present invention, a terminal can appropriately perform a random-access process. In a terminal (100), a wireless transmission unit (111) transmits a random-access signal including at least a data part. A rank determination unit (107) controls the configuration of the data part on the basis of a parameter regarding the transmission of the random-access signal.

Dans la présente invention, un terminal peut effectuer de manière appropriée un processus d'accès aléatoire. Dans un terminal (100), une unité de transmission sans fil (111) transmet un signal d'accès aléatoire comprenant au moins une partie de données Une unité de détermination de rang (107) commande la configuration de la partie de données sur la base d'un paramètre concernant la transmission du signal d'accès aléatoire.
