背景技术Background technique
图1 为现有技术的无线帧结构示意图,如图1所示,一个无线帧由5个长度为5ms的子帧组成,每个子帧为640Ts,其中,子帧0为下行子帧,子帧2、3、4为上行子帧,子帧1为特殊子帧,包括3个域,分别为下行导频时隙DwPTS、GP和上行导频时隙UpPTS。Figure 1 is a schematic diagram of a wireless frame structure in the prior art. As shown in Figure 1, a wireless frame is composed of 5 subframes with a length of 5ms, and each subframe is 640Ts, wherein, subframe 0 is a downlink subframe, and subframe 2, 3, and 4 are uplink subframes, and subframe 1 is a special subframe, including 3 fields, which are downlink pilot time slots DwPTS, GP and uplink pilot time slots UpPTS.
物理上行链路控制信道(Physical Uplink Control Channel,简称“PUCCH”)承载物理下行共享信道(Physical Downlink Share Control Channel,简称“PDSCH”)的ACK/NACK反馈信息。PUCCH支持多种PUCCH格式,例如PUCCH格式0~PUCCH格式3,不同的PUCCH格式在时域占用的SC-FDMA符号或者子帧不同。现有技术中,终端,即UE,在检测到通过PDSCH完成数据传输(包括完成重传数据传输)时的无线帧为无线帧n,确定ACK/NACK反馈信息,并在该无线帧的下一个无线帧n+1中发送相应的ACK/NACK反馈信息。由于,无线帧n和无线帧n+1之间存在时间间隔,因此,不能满足低时延业务的需求。A physical uplink control channel (Physical Uplink Control Channel, "PUCCH" for short) carries ACK/NACK feedback information of a physical downlink shared channel (Physical Downlink Share Control Channel, "PDSCH" for short). The PUCCH supports multiple PUCCH formats, such as PUCCH format 0 to PUCCH format 3. Different PUCCH formats occupy different SC-FDMA symbols or subframes in the time domain. In the prior art, the terminal, that is, the UE, detects that the wireless frame when the data transmission (including retransmission data transmission is completed) is completed through the PDSCH is the wireless frame n, determines the ACK/NACK feedback information, and transmits the information in the next wireless frame Corresponding ACK/NACK feedback information is sent in radio frame n+1. Since there is a time interval between radio frame n and radio frame n+1, the requirement of low-latency services cannot be met.
