Description

确定方法、终端设备及网络设备
本申请要求于2018年09月07日提交国家知识产权局、申请号为201811045911.0、申请名称为“确定方法、终端设备及网络设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种确定方法、终端设备及网络设备。
背景技术
目前，用户设备(User Equipment，UE)在接收到基站发送的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)后，需要反馈确认信息(Acknowledgement，ACK)/否认信息(Negative ACKnowledgment，NACK)，以告知基站是否正确接收到PDSCH接收正确，辅助基站根据ACK/NACK判断后续是否需要重传PDSCH。
在NR-U场景下，由于UE在发送ACK/NACK时需要先进行信道侦听，判定信道是否忙绿，如果侦听结果为忙碌，则UE将不能发送信息，如果信道为空闲，UE才可能发送ACK/NACK等上行控制信息。
然而，在侦听结果为忙碌的情况下，由于UE无法向基站发送ACK/NACK，从而导致基站无法获知是否重传PDSCH，使得基站后续只能将之前发送的PDSCH全部重传，进而引起资源浪费。
发明内容
