Abstract: front page image
(EN)The present invention provides a method for user equipment receiving multi-flow data with respect to one evolved packet system (EPS) bearer through a macro base station (macro eNB) and a small base station (small eNB) in a wireless communication system supporting dual connectivity. The method comprises the steps of: a packet data convergence protocol (PDCP) entity of the user equipment receiving PDCP packet data units (PDU) through the macro base station and the small base station from a PDCP entity of the macro base station; obtaining PDCP service data units (SDU) corresponding to PDCP PDUs; and receiving from the macro base station information related to a sequence timer for the PDCP SDUs through a radio resource control (RRC) message, wherein the PDCP SDUs are indicated by a predefined PDCP sequence number (SN).
(FR)La présente invention concerne un procédé pour un équipement utilisateur recevant des données en flux multiple par rapport à une porteuse de système de paquets évolués (EPS) au moyen d'une macrostation de base (macro-eNB) et d'une petite station de base (petit eNB) dans un système de communication sans fil supportant la double connectivité. Le procédé comprend les étapes dans lesquelles : une entité de protocole de convergence de données en paquets (PDCP) de l'équipement utilisateur reçoit des unités de données en paquets (PDU) PDCP au moyen de la macrostation de base et de la petite station de base d'une entité PCDP de la macrostation de base ; l'entité obtient des unités de données de service (SDU) PDCP correspondant aux PDU PDCP ; et l'entité reçoit de la macrostation de base des informations associées un temporiseur de séquence pour les SDU PDCP au moyen d'un message de commande de ressource radio (RRC), les SDU PDCP étant indiquées par un numéro de séquence (SN) PDCP prédéfini.
(KO)본 발명은 이중 연결(dual connectivity)을 지원하는 무선 통신 시스템에서 단말(UE)이 매크로 기지국(Macro eNB) 및 스몰 기지국(Small eNB)을 통하여 하나의 EPS(Evolved Packet System) 베어러(bearder)에 대한 멀티 플로우(multi flow) 데이터를 수신하는 방법을 제공한다. 상기 방법은 상기 단말의 PDCP(Packet Data Convergence Protocol) 엔티티(entity)는 상기 매크로 기지국의 PDCP 엔티티로부터 상기 매크로 기지국 및 상기 스몰 기지국을 통하여 PDCP PDU들을 수신하는 단계, 상기 PDCP PDU(Packet Data Unit)들에 대응하는 PDCP SDU(Service Data Unit)들을 획득하는 단계, 및 상기 매크로 기지국으로부터 RRC(radio resource control) 메시지를 통하여 상기 PDCP SDU들에 대한 순차 타이머에 관한 정보를 수신하는 단계를 포함하되, 상기 PDCP SDU들은 미리 정의된 PDCP SN(Sequence Number)으로 지시됨을 특징으로 한다.
