Abstract

Description
本发明涉及上行控制信号传输技术,尤其涉及一种上行控制信号传输方法及装置、用户终端、存储介质。
在第三代合作伙伴项目(3GPP,3rd Generation Partnership Project)长期演进(LTE,Long Term Evolution)及高级长期研究(LTE-A,LTE-Advanced)系统中,传输时间间隔(TTI,Transmission Time Interval)是下行和上行传输调度在时域上的基本单位。如在LTE/LTE-A频分双工(FDD,Frequency Division Duplex)系统中,时间维度上被分成长度为10ms的无线电帧,其中每个无线电帧包括10个子帧,TTI长度等于子帧长度为1ms。每个子帧包括两个时隙,每一个时隙的长度为0.5ms。每个下行时隙含有7个正交频分复用(OFDM,Orthogonal Frequency Division Multiplexing)符号(扩展循环前缀下为6个OFDM符号);每个上行时隙含有7个单载波频分复用(SC-FDMA,Single Carrier-Frequency Division Multiplexing Access)符号(扩展循环前缀下为6个SC-FDMA符号)。
在3GPP后续演进如第五代(5G)移动通信系统相对LTE/LTE-A系统将支持更高速率(Gbps)、巨量链接(1M/Km2)、超低时延(1ms)、更高的可靠性、百倍的能量效率提升等以支撑新的需求变化。其中,超低时延作为5G技术的关键指标,直接影响着如车联网、工业自动化、远程控制、智能电网等时延受限业务的发展。
然而,现有LTE/LTE-A系统的空口时延指标为10ms左右,将不再满足需求。一种有效的解决方案是降低TTI长度,如将现在1ms长度的TTI
降低为0.5ms甚至1~2个OFDM符号的长度,可以成倍的降低最小调度时间,进而成倍地降低单次传输时延。
当TTI长度降低时,现有物理上行控制信道(PUCCH,Physical Uplink Control Channel)中用于发送确认指令(ACK,Acknowledgement)、非确认指令(NACK,Negative Acknowledgement)消息及调度请求(SR,Scheduling Request)的传输结构将无法直接使用。同时,TTI内符号数降低将导致参考符号(RS,Reference Symbol)开销过大。因此,目前仍未有合适的解决技术方案。
