Abstract
(EN)
A wireless terminal according to one embodiment of the present invention transmits data belonging to one bearer to two wireless communication devices. The wireless terminal is provided with a control unit that carries out processing in which, when the amount of data accumulated in a predetermined buffer is less than a threshold value, and one wireless communication device is designated as the destination of a buffer status report, the buffer status report is transmitted only to the one wireless communication device. When the quantity of data is less than the threshold value, and a wireless link failure with the one wireless communication device is detected, the control unit changes the destination of the buffer status report from the one wireless communication device to the other wireless communication device.

Selon un mode de réalisation, la présente invention concerne un terminal sans fil qui transmet à deux dispositifs de communication sans fil des données appartenant à une porteuse. Le terminal sans fil est muni d'une unité de commande qui effectue un traitement au cours duquel, si la quantité de données accumulées dans un tampon prédéterminé est inférieure à une valeur seuil, et si le dispositif de communication sans fil est désigné comme destinataire d'un rapport d'état du tampon, le rapport d'état du tampon n'est transmis qu'audit dispositif de communication sans fil. Si la quantité de données est inférieure à la valeur de seuil, et si une défaillance de liaison sans fil avec le dispositif de communication sans fil est détectée, l'unité de commande change de destinataire du rapport d'état du tampon en passant dudit dispositif de communication sans fil à l'autre dispositif de communication sans fil.

一つの実施形態に係る無線端末は、1つのベアラのデータを2つの無線通信装置に送信する。前記無線端末は、所定のバッファに蓄積されたデータ量が閾値を下回っており、かつ、バッファ状態報告の送信先として一方の無線通信装置が指定されている場合、前記一方の無線通信装置にのみ前記バッファ状態報告を送信する処理を行う制御部を備える。前記制御部は、前記データ量が前記閾値を下回っており、かつ、前記一方の無線通信装置との無線リンク障害を検知した場合、前記バッファ状態報告の送信先を前記一方の無線通信装置から他方の無線通信装置に変更する。
