Title (EN) DOWNLINK SYNCHRONOUS TRANSMISSION CONTROL METHOD, SYSTEM AND COORDINATED MULTIPOINT TRANSMISSION NODE
(FR) PROCÉDÉ ET SYSTÈME DE COMMANDE DE TRANSMISSION SYNCHRONE EN LIAISON DESCENDANTE, ET NœUD DE TRANSMISSION MULTIPOINTS COORDONNÉ
(ZH) 一种下行同步发射控制方法、系统及协作多点传输节点
Abstract:
(EN) A downlink synchronous transmission control method, system and coordinated multipoint transmission node are provided in the invention. The method includes the following steps: a base station configures time-advance information, and sends the time-advance information to a coordinated multipoint transmission node; when the coordinated multipoint transmission node transmits a downlink signal, the initial time of the downlink transmission is advanced for a certain period of time according to the time-advance information. The invention enables multi-path signals reaching a user equipment (UE) to fall in a cyclic prefix (CP) receiving window more easily, thus increasing the amount of useful signals received by the UE and improving the receiving quality of the UE.
(FR) L'invention porte sur un procédé et un système de commande de transmission synchrone en liaison descendante, et sur un nœud de transmission multipoints coordonné. Le procédé comprend les étapes suivantes : une station de base configure des informations d'avance temporelle, et envoie les informations d'avance temporelle à un nœud de transmission multipoints coordonné; lorsque le nœud de transmission multipoints coordonné transmet un signal de liaison descendante, l'instant initial de la transmission en liaison descendante est avancé d'une certaine période de temps conformément aux informations d'avance temporelle. L'invention permet à des signaux de propagation par trajets multiples atteignant un équipement utilisateur (UE) de tomber plus facilement dans une fenêtre de réception de préfixe cyclique (CP), augmentant ainsi le volume de signaux utiles reçus par l'UE et améliorant la qualité de réception de l'UE.
(ZH) 本发明公开了一种下行同步发射控制方法、系统及协作多点传输节点,其中, 所述方法包括: 基站配置时间提前信息, 并下发给协作多点传输节点;所述协作多点传输节点在发射下行信号时,根据所述时间提前信息将下行发射的起始时间提前一特定时间。本发明使得到达UE处的多径信号能更加容易地落在CP接收窗内, 增加了UE接收的有用信号量, 提高了UE的接收质量。
