背景技术
现有的LTE(Long-term Evolution，长期演进)及LTE-A(Long Term Evolution Advanced，增强的长期演进)系统中，TTI(Transmission Time Interval，传输时间间隔)或者子帧(Subframe)或者PRB(Physical Resource Block，物理资源块)对(Pair)在时间上对应一个ms(milli-second，毫秒)。一个LTE子帧包括两个时隙(Time Slot)，分别是第一时隙和第二时隙，且所述第一时隙和所述第二时隙分别占用一个LTE子帧的前半个毫秒和后半个毫秒。
3GPP(3rd Generation Partner Project，第三代合作伙伴项目)Release 14中的Latency Reduction(LR，延迟降低)课题中，一个重要的应用目的就是低延迟通信。传统的LTE系统中，下行PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的传输及与之对应的HARQ-ACK(Hybrid Automatic Repeat request Acknowledgment，混合自动重传请求确认)符合严格的预定义时序关系。针对降低延迟的需求，传统的LTE帧结构需要被重新设计，与之相对应的，新的下行传输及下行传输针对的上行反馈也需要被重新设计。
发明内容
Release 14延迟降低相关的Study Item(研究课题)中，一个需要被研究的方向就是下行传输及下行传输针对的上行反馈的时序关系的设计，相较LTE系统，为实现低延迟传输的目的，下行传输及针对的上行HARQ-ACK的时间间隔将会降低。然而，当UE(User Equipment，用户设备)可以同时支持基于1ms的TTI(Transmission Time Interval，传 输时间间隔)和基于小于1ms的sTTI(Short Transmission Time Interval，缩短的传输时间间隔)的多个下行传输时，所述多个下行传输的上行HARQ-ACK有可能会在同一子帧中上传。
一种直观的解决方法，就是基于1ms的TTI的UL(Uplink，上行)HARQ-ACK在传统的PUCCH(Physical Uplink Control Channel,物理上行控制信道)或者PUSCH(Physical Uplink Shared Channel,物理上行共享信道)中传输，基于小于1ms的sTTI的UL HARQ-ACK在新设计的sPUCCH(Short Latency Physical Uplink Control Channel,短延迟物理上行控制信道)或者sPUSCH(Short Latency Physical Uplink Shared Channel,短延迟物理上行共享信道)中传输。但显然此种方法会增加UE上行的功率，对于功率受限的用于，将会影响性能。同时，因为发送多个UCI(Uplink Control Information，上行控制信息)也会导致效率较低。
