Abstract:
(EN) An eNB (100A) notifies a gNB (100B) of a set position indicating that a PDCP entity that is the entity of a packet data convergence protocol layer used in a split bearer is set to either the eNB (100A) or the gNB (100B). The gNB (100B) sets a protocol stack used in the split bearer on the basis of the set position of the PDCP entity notified from the eNB (100A).
(FR) Selon la présente invention, un eNB (100A) notifie un gNB (100B) d'une position définie indiquant qu'une entité PDCP qui est l'entité d'une couche de protocole de convergence de données par paquets utilisée dans une porteuse divisée, est réglée soit sur l'eNB (100A), soit sur le gNB (100B). Le gNB (100B) définit une pile de protocoles utilisée dans la porteuse divisée sur la base de la position définie de l'entité PDCP notifiée depuis l'eNB (100A).
(JA) eNB(100A)は、スプリットベアラに用いられるパケット・データ・コンバージェンス・プロトコル・レイヤのエンティティであるPDCPエンティティをeNB(100A)またはgNB(100B)の何れかに設定することを示す設定位置をgNB(100B)に通知する。gNB(100B)が、eNB(100A)から通知されたPDCPエンティティの設定位置に基づいて、スプリットベアラに用いられるプロトコルスタックを設定する。
