Abstract
(EN)
Provided is a low-latency wireless communication technology for new radio (NR). This communication system is provided with a plurality of base stations and a communication terminal device configured to be able to perform wireless communication with the plurality of base stations. Each of the plurality of base stations includes a plurality of Distributed Units (DU) configured to be able to perform wireless communication with the communication terminal device, and a Central Unit (CU) which controls the plurality of DUs. The communication terminal device (UE), when selecting a DU for connection, selects a DU (DU#1-2) belonging to a previous CU (CU#1) which is the CU to which the previously connected DU (DU#1-1) belongs, preferentially over a DU (DU#2-1) belonging to another CU (CU#2).

L'invention concerne une technologie de communication sans fil à faible latence pour une nouvelle radio (NR). Ce système de communication est pourvu d'une pluralité de stations de base et d'un dispositif terminal de communication configuré de sorte à pouvoir établir une communication sans fil avec la pluralité de stations de base. Chacune de la pluralité de stations de base comprend une pluralité d'unités distribuées (DU) configurées de sorte à pouvoir établir une communication sans fil avec le dispositif terminal de communication, et une unité centrale (CU) qui commande la pluralité de DU. Le dispositif terminal de communication (UE), lors de la sélection d'une DU pour la connexion, sélectionne une DU (DU # 1-2) appartenant à une CU précédente (CU #1) qui est la CU à laquelle appartient la DU précédemment connectée (DU # 1-1), de préférence par rapport à une DU (DU # 2-1) appartenant à une autre CU (CU # 2).
