(EN) Method and apparatus for transmitting feedback information

Abrégé
(EN)
The invention discloses a method and apparatus for transmitting feedback information, for solving the problem that there is not yet a scheme for transmitting uplink control information corresponding to downlink carrier waves scheduled by multiple base stations under the condition of a double-connection scene in the prior art. A terminal provided by the invention receives data on a first carrier wave and receives data on a second carrier wave, wherein the data on the first carrier wave is scheduled by a first base station, and the data on the second carrier wave is scheduled by a second base station; generating first uplink control information for the first carrier wave and/or generating second uplink control information for the second carrier wave; and sending the generated uplink control information on one uplink carrier wave through a PUCCH and/or a PUSCH, wherein the uplink control information comprises at least one from the first uplink control information and the second uplink control information. Therefore, the terminal whose uplink data is only sent on one carrier wave can timely feed back the uplink control information corresponding to downlink carrier waves scheduled by the different base stations, and it is ensured that the different base stations can timely obtain feedback information corresponding to the downlink carrier waves scheduled by themselves.

本发明公开了一种传输反馈信息的方法和装置,用于解决目前双连接场景下还没有传输多个基站调度的下行载波对应的上行控制信息的方案。本发明中的终端在第一载波上接收数据及在第二载波上接收数据,第一载波上的数据由第一基站调度,第二载波上的数据由第二基站调度;对第一载波产生第一上行控制信息和/或对第二载波产生第二上行控制信息;在一个上行载波上通过PUCCH和/或PUSCH发送所产生的上行控制信息,上行控制信息包括第一上行控制信息和第二上行控制信息中的至少一种。因此,上行仅在一个载波发送的终端能及时反馈不同基站调度的下行载波对应的上行控制信息,保证不同基站能及时获得自身调度的下行载波对应的反馈信息。
