Abstract

La présente invention concerne un procédé et un appareil d'accès aléatoire. Le procédé est appliqué à une station de base. Le procédé consiste : à répartir, pour un terminal, une porteuse de liaison montante spécifiée utilisée lorsque le terminal applique un type spécifié d'accès aléatoire ; à générer des informations de configuration de porteuse, les informations de configuration de porteuse étant utilisées pour caractériser le type spécifié et la porteuse de liaison montante spécifiée ; et à envoyer les informations de configuration de porteuse au terminal, de telle sorte que le terminal applique le type spécifié d'accès aléatoire sur la porteuse de liaison montante spécifiée lors de l'application du type spécifié d'accès aléatoire. Par conséquent, la présente invention peut garantir que lorsque différents types d'accès aléatoires sont appliqués, un accès aléatoire correspondant peut être appliqué sur une porteuse de liaison montante avec de bons signaux et des signaux stables, ce qui permet d'éviter une faible latence provoquée par un échec d'accès aléatoire et d'améliorer le taux de réussite et la vitesse de l'accès aléatoire.
