阅读说明：本技术 发送、接收反馈信息的方法和设备 (Method and equipment for sending and receiving feedback information ) 是由 林亚男 吴作敏 于 2019-09-30 设计创作，主要内容包括：提供了一种发送、接收反馈信息的方法和设备,所述方法包括：终端设备接收第一信令,所述第一信令用于指示所述终端设备传输至少一个目标组对应的反馈信息,其中,所述至少一个目标组中的同一目标组对应的下行信道属于同一载波；所述终端发送反馈信息码本,所述反馈信息码本中包括所述至少一个目标组对应的反馈信息。通过所述第一信令,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,避免了由于某个载波LBT失败会造成其反馈信息存在大量的冗余信息,能够提高反馈效率。(A method and a device for sending and receiving feedback information are provided, the method comprises: a terminal device receives a first signaling, where the first signaling is used to instruct the terminal device to transmit feedback information corresponding to at least one target group, where downlink channels corresponding to a same target group in the at least one target group belong to a same carrier; and the terminal sends a feedback information codebook, wherein the feedback information codebook comprises feedback information corresponding to the at least one target group. Through the first signaling, the terminal equipment can be triggered to feed back the feedback information of the downlink channel by taking at least one group corresponding to one carrier as a unit instead of triggering the terminal equipment to feed back the feedback information of the downlink channel by taking a plurality of carriers as a unit, so that the feedback information of a certain carrier caused by LBT failure is prevented from having a large amount of redundant information, and the feedback efficiency can be improved.)
