Title (EN) METHOD FOR DETERMINING DMRS PORT MAPPING, AND BASE STATION AND TERMINAL
(FR) PROCÉDÉ POUR DÉTERMINER UN DMRS, ET STATION DE BASE ET TERMINAL
(ZH) 一种确定DMRS的端口映射的方法、基站和终端
Abstract:
(EN) Provided are a method for determining DMRS port mapping, and a base station and terminal, the method on the base-station side being: a base station determining an index of a beam corresponding to a terminal; according to the correlation between the index of the beam corresponding to said terminal and the mapping number of the DMRS port, the base station determining the mapping number of the DMRS port of the terminal; according to the determined mapping number of the DMRS port of the terminal, the base station determining the port mapping of the DMRS of the terminal; according to the DMRS port mapping, the base station sending the DMRS to the terminal. In the method, a correlation between beam information and DMRS port mapping is established, such that there is a high likelihood that two terminals corresponding to different beams will be mapped to different DMRS ports.
(FR) L’invention concerne un procédé pour déterminer un mappage de port de signal de référence de démodulation (DMRS), ainsi qu’une station de base et un terminal, le procédé sur le côté station de base comprenant les opérations suivantes : une station de base détermine un indice d’un faisceau correspondant à un terminal ; selon la corrélation entre l’indice du faisceau correspondant audit terminal et le numéro de mappage du port de DMRS, la station de base détermine le numéro de mappage du port de DMRS du terminal ; selon le numéro de mappage déterminé du port de DMRS du terminal, la station de base détermine le mappage de port du DMRS du terminal ; selon le mappage de port de DMRS, la station de base envoie le DMRS au terminal. Dans le procédé, une corrélation entre des informations de faisceau et un mappage de port de DMRS est établie, de telle sorte qu’il existe une probabilité élevée que deux terminaux correspondant à différents faisceaux soient mappés à différents ports de DMRS.
(ZH) 一种确定DMRS的端口映射的方法、基站和终端,基站侧的方法为:基站确定终端对应的波束的索引;所述基站根据设置的所述终端对应的波束的索引与DMRS端口的映射编号之间的对应关系,确定所述终端的DMRS端口的映射编号;所述基站根据确定的所述终端的DMRS端口的映射编号,确定所述终端的DMRS的端口映射;所述基站根据所述DMRS的端口映射向所述终端发送DMRS。上述方法通过建立波束信息与DMRS的端口映射之间的关联关系,使得对应不同波束的两个终端有很大的可能性被映射到不同的DMRS端口。
