Abstract:
(EN) In the present invention, an eNB (100A) sets a split bearer which goes through an SCG from a core network and splits from the SCG into the eNB (100A) that is included in an MCG. If a UE (200) reconnects to the same SCG as the one prior to the release of a portion of the resources of the split bearer, the eNB (100A) resets the split bearer which uses a held upper layer resource. The UE (200) executes a random access procedure with a gNB (100B) included in the reconnected SCG.
(FR) Dans la présente invention, un eNB (100A) paramètre une porteuse divisée qui passe par un SCG à partir d'un réseau central et se divise à partir du SCG en l'eNB (100A) qui est inclus dans un MCG. Si un UE (200) se reconnecte au même SCG que celui avant la libération d'une partie des ressources de la porteuse divisée, l'eNB (100A) paramètre à nouveau la porteuse divisée qui utilise une ressource de couche supérieure conservée. L'UE (200) exécute une procédure d'accès aléatoire à l'aide d'un gNB (100B) inclus dans le SCG reconnecté.
(JA) eNB(100A)は、コアネットワークからSCGを経由するとともにSCGからMCGに含まれるeNB(100A)に分岐するスプリットベアラを設定する。UE(200)がスプリットベアラの一部リソースの解放前と同一のSCGに再接続する場合、eNB(100A)は、保持している上位レイヤリソースを用いたスプリットベアラを再設定する。UE(200)は、再接続されるSCGに含まれるgNB(100B)とランダムアクセス手順を実行する。
