Title (EN) MOBILE COMMUNICATION METHOD, RELAY NODE, AND WIRELESS BASE STATION
(FR) PROCÉDÉ DE COMMUNICATION MOBILE, NŒUD DE RELAIS ET STATION DE BASE SANS FIL
(JA) 移動通信方法、リレーノード及び無線基地局
Abstract:
(EN) In order to reduce the interference to a receiver from a relay node (RN) due to simultaneous transmission/reception processing in the Un wireless bearer and the Uu wireless bearer when the relay node (RN) is handed over from a wireless base station (DeNB#1) to another wireless base station (DeNB#2), the handover procedure of the mobile communication method according to the present invention includes a step (A) in which the relay node (RN) uses a "RRC Connection Reconfiguration Complete" message to inform the other wireless base station (DeNB#2) of "Un subframe pattern #1", which expresses the pattern in Un subframe #1, and "RN subframe config req", which indicates whether or not it is necessary to establish Un subframe #2 in the wireless bearer #2 between the other wireless base station (DeNB#2) and the relay node (RN).
(FR) Selon l'invention, pour réduire les interférences vers un récepteur à partir d'un nœud de relais (RN) en raison d'un traitement de transmission/réception simultanées dans le support sans fil Un et le support sans fil Uu lorsque le nœud de relais (RN) est transféré d'une station de base sans fil (DeNBn°1) à une autre station de base sans fil (DeNBn°2), la procédure de transfert du procédé de communication mobile comprend une étape (A) dans laquelle le nœud de relais (RN) utilise un message « Reconfiguration de connexion RRC complète » pour informer l'autre station de base sans fil (DeNBn°2) d'un « Modèle de sous-trame Un n°1 », qui exprime le modèle dans la sous-trame Un n°1, et « Config de sous-trame RN req. », qui indique s'il est nécessaire ou non d'établir une sous-trame Un n°2 dans le support sans fil n°2 entre l'autre station de base sans fil (DeNBn°2) et le nœud de relais (RN).
(JA)  リレーノードRNが無線基地局DeNB#1から無線基地局DeNB#2にハンドオーバした場合であっても、Un無線ベアラ及びUu無線ベアラにおける送受信処理が同時に行われることから引き起こされるリレーノードRN自身の受信機への干渉を低減する。本発明に係る移動通信方法は、上述のハンドオーバ手順において、リレーノードRNが、無線基地局DeNB#2に対して、「RRC Connection Reconfiguration Complete」によって、Unサブフレーム#1のパターンを示す「Un subframe pattern#1」、及び、無線基地局DeNB#2とリレーノードRNとの間の無線ベアラ#2においてUnサブフレーム#2を設定する必要があるか否かについて示す「RN subframe config req」を通知する工程Aを有する。
