Title (EN) COMMUNICATION CONTROL METHOD, WIRELESS TERMINAL, AND BASE STATION
(FR) PROCÉDÉ DE COMMANDE DE COMMUNICATION, TERMINAL SANS FIL, ET STATION DE BASE
(JA) 通信制御方法、無線端末、及び基地局
Abstract:
(EN) The wireless terminal according to an embodiment is used in a mobile communication system which supports uplink transmission using unlicensed spectrum. The wireless terminal is provided with a control unit that carries out LBT prior to the uplink transmission. The control unit applies a first LBT system to the LBT upon receipt, from a base station, of information indicating the first LBT system. The control unit applies a second LBT system to the LBT upon receipt, from the base station, of information indicating the second LBT system in which an LBT time is shorter than that in the first LBT system.
(FR) Un terminal sans fil selon un mode de réalisation est utilisé dans un système de communication mobile prenant en charge une transmission en liaison montante faisant appel à un spectre sans licence. Le terminal sans fil est pourvu d'une unité de commande qui exécute un LBT avant la transmission en liaison montante. L'unité de commande applique un premier système LBT au LBT lors de la réception, à partir d'une station de base, d'informations indiquant le premier système LBT. L'unité de commande applique un second système LBT au LBT lors de la réception, en provenance de la station de base, d'informations indiquant le second système LBT dans lequel un temps LBT est plus court que celui du premier système LBT.
(JA) 一実施形態に係る無線端末は、アンライセンスドスペクトラムを用いた上りリンク送信をサポートする移動通信システムにおいて用いられる。前記無線端末は、前記上りリンク送信の前にLBTを行う制御部を備える。前記制御部は、第1のLBT方式を示す情報を基地局から受信したことに応じて、前記第1のLBT方式を前記LBTに適用する。前記制御部は、前記第1のLBT方式よりもLBT時間が短い第2のLBT方式を示す情報を前記基地局から受信したことに応じて、前記第2のLBT方式を前記LBTに適用する。
