Abstract:
(EN) Provided are a method and apparatus for transmitting and acquiring common downlink control information. The method comprises: grouping and scrambling common downlink control information by means of pre-set grouping and scrambling information corresponding to each terminal group on a one-to-one basis to obtain grouped common downlink control information; and sending a physical downlink control channel (PDCCH) bearing target common downlink control information to a terminal, so that the terminal demodulates the PDCCH according to the pre-set grouping and scrambling information to obtain the target common downlink control information, wherein the target common downlink control information is common downlink control information, corresponding to a target terminal group to which the terminal belongs, in the grouped common downlink control information. In the present disclosure, the purpose of transmitting and acquiring common downlink control information based on a terminal group is achieved.
(FR) L'invention concerne un procédé et un appareil pour transmettre et acquérir des informations de commande de liaison descendante communes. Le procédé consiste à : grouper et brouiller des informations de commande de liaison descendante communes au moyen d'informations de regroupement et de brouillage prédéfinies correspondant à chaque groupe de terminaux sur une base biunivoque pour obtenir des informations de commande de liaison descendante communes groupées ; et envoyer un canal de commande de liaison descendante physique (PDCCH) portant des informations de commande de liaison descendante communes cibles à un terminal, de telle sorte que le terminal démodule le PDCCH en fonction des informations de regroupement et de brouillage prédéfinies pour obtenir les informations de commande de liaison descendante communes cibles, les informations de commande de liaison descendante communes cibles étant des informations de commande de liaison descendante communes, correspondant à un groupe de terminaux cible auquel le terminal appartient, dans les informations de commande de liaison descendante communes groupées. Dans la présente invention, le but de transmettre et d'acquérir des informations de commande de liaison descendante communes sur la base d'un groupe de terminaux est obtenu.
(ZH) 本公开提供一种公共下行控制信息的传输、获取方法及装置,其中,所述方法包括:通过与每个终端分组一一对应的预设分组加扰信息对公共下行控制信息进行分组加扰,得到分组公共下行控制信息;发送承载目标公共下行控制信息的物理下行控制信道PDCCH到终端,以使所述终端根据所述预设分组加扰信息对所述PDCCH进行解调,获得所述目标公共下行控制信息;其中,所述目标公共下行控制信息是所述分组公共下行控制信息中与所述终端所属的目标终端分组对应的公共下行控制信息。本公开中,实现了基于终端分组对公共下行控制信息进行传输和获取的目的。
