(FR) SYSTÈME ET PROCÉDÉ DE COMMUNICATIONS UTILISANT UNE LIAISON MONTANTE SUPPLÉMENTAIRE
Abstract
(EN)
A computer-implemented method for operating a user equipment (UE) includes measuring a channel quality of a channel associated with a first uplink channel and a second uplink channel, determining that the channel quality is between a first channel quality threshold and a second channel quality threshold, and based thereon, selecting either the first uplink channel or the second uplink channel for an uplink transmission in accordance with a current location of the UE, historical information of successful uplink channel access attempts, and a distance threshold, and performing an uplink random access procedure in accordance with the selected uplink channel.
(FR)
La présente invention concerne un procédé mis en œuvre par ordinateur destiné à faire fonctionner un équipement utilisateur (UE), consistant : à mesurer une qualité de canal d'un canal associé à un premier canal de liaison montante et un second canal de liaison montante, à déterminer que la qualité de canal s'inscrit entre un premier seuil de qualité de canal et un second seuil de qualité de canal, et sur cette base, à sélectionner soit le premier canal de liaison montante, soit le second canal de liaison montante destiné à une transmission de liaison montante conformément à un emplacement actuel de l'UE, à des informations historiques de tentatives d'accès de canal de liaison montante réussies, et à un seuil de distance, et à réaliser une procédure d'accès aléatoire de liaison montante conformément au canal de liaison montante sélectionné.
