Description

传输数据的方法和终端 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及一种传输数据的方法和终端。
背景技术
随着空口技术的发展和其应用的不断扩展,在未来的通信技术中,降低传输时延成为通信的关键指标之一。例如,移动终端的实时远程监控(real-time remote computing for mobile terminals)的端到端的传输时延要求为小于10ms,高效安全业务(traffic efficienty and safety)的传输时延要求为小于5ms,其它的业务则可能要求更短的传输时延。
降低传输时延的关键技术之一就是缩短传输时间间隔(Transmission Time Interval,TTI)。目前,长期演进(Long Term Evolution,LTE)系统的TTI的长度为1ms,长期演进技术升级版13(LTE-Advanced Release 13,LTE-A Rel-13)已经确定开始研究使用更短的TTI进行数据传输。
短TTI的优势在于缩短传输时延,但相应的代价是控制信令开销高,频谱效率低。对于同时存在多种类型业务的终端,若根据最小时延要求的业务确定统一的TTI,会造成资源浪费。为保证传输时延,同时兼顾系统效率,可以动态调度终端使用不同的TTI长度,即传输短时延业务时使用短TTI,传输其他业务时使用常规TTI。因此,LTE-A Rel-13要求支持短TTI传输的载波上同时要保证对现有LTE系统的兼容性,即要同时兼容1ms TTI。
当前,LTE系统支持两种不同的数据调度方式,即半静态调度和动态调度。其中,半静态调度是指基站通过高层信令指示终端调度信息,包括:调度周期,物理资源位置,调制编码等级等。基站通过向终端发送一条下行控制信令(Downlink Control Information,DCI),触发终端进行半静态调度后,终端每隔固定的周期在相同的频率资源上进行数据传输。动态调度是指基站确定进行一次数据传输,则向终端发送一条DCI,终端根据DCI的指示在相应的时频资源上进行数据传输,动态调度无固定周期。
在不支持端TTI的系统中,动态调度与半静态调度对应的TTI是相同的。当动态调度与半静态调度所对应的时频资源重叠时,由于动态调度与半静态 调度对应的TTI相同,动态调度与半静态调度对应的数据到达时间、基站调度时间、数据处理时间等均相同,因而终端可以将原半静态调度的数据和动态调度的数据合并到一起进行传输。例如,终端将数据合并后全部在动态调度的时频资源上进行传输。即在半静态调度传输的子帧中,如果终端接收到动态调度,则接收或发送动态调度数据(基站将半静态调度的数据打包至动态调度的数据中)。
然而,当LTE系统动态调度和半静态调度对应的TTI不同时,由于同调度对应的数据到达时间、基站调度时间、数据处理时间不相同,导致现有的动态调度覆盖(override)半静态调度的工作机制将不再适用。

下面简要介绍本发明实施例的涉及的相关技术及概念。
随着空口技术的发展和其应用的不断扩展,在未来的通信技术中,降低传输时延成为通信的关键指标之一。例如,移动终端的实时远程监控(real-time remote computing for mobile terminals)的端到端的传输时延要求为小于10ms,高效安全业务(traffic efficienty and safety)的传输时延要求为小于5ms,其它的业务则可能要求更短的传输时延。表1列出了LTE系统的版本8(Release 8,Rel 8)和版本9(Release 9,Rel 9)中,下行传输的典型的传输时延。
表1
序号 描述 时长(ms)
1 到达数据处理(processes incoming data) 3
2 TTI对齐(TTI alignment) 0.5
3 发送下行数据(Transmission of DL data) 1
4 终端解码(Data decoding in UE) 3
  总时延(total delay) 7.5
其中,到达数据处理及终端解码所产生的时延主要与TTI的长度有关。因此,降低传输时延的关键技术之一就是缩短TTI。目前,LTE系统的TTI的长度为1ms,长期演进技术升级版13(LTE-Advanced Release 13,LTE-ARel-13)已经确定开始研究使用更短的TTI进行数据传输。
短TTI的优势在于缩短传输时延,但相应的代价是控制信令开销高,频谱效率低。对于同时存在多种类型业务的终端,若根据最小时延要求的业务 确定统一的TTI,会造成资源浪费。为保证传输时延,同时兼顾系统效率,可以动态调度终端使用不同的TTI长度,即传输短时延业务时使用短TTI,传输其他业务时使用常规TTI。因此,LTE-A Rel-13要求支持短TTI传输的载波上同时要保证对现有LTE系统的兼容性,即要同时兼容1ms TTI。
当前,LTE系统支持两种不同的数据调度方式,即半静态调度和动态调度。其中,半静态调度是指基站通过高层信令指示终端调度信息,包括:调度周期,物理资源位置,调制编码等级等。基站通过向终端发送一条下行控制信令(Downlink Control Information,DCI),触发终端进行半静态调度后,终端每隔固定的周期在相同的频率资源上进行数据传输。动态调度是指基站确定进行一次数据传输,则向终端发送一条DCI,终端根据DCI的指示在相应的时频资源上进行数据传输,动态调度无固定周期。
在不支持端TTI的系统中,动态调度与半静态调度对应的TTI是相同的。当动态调度与半静态调度所对应的时频资源重叠时,由于动态调度与半静态调度对应的TTI相同,动态调度与半静态调度对应的数据到达时间、基站调度时间、数据处理时间等均相同,因而终端可以将原半静态调度的数据和动态调度的数据合并到一起进行传输。例如,终端将数据合并后全部在动态调度的时频资源上进行传输。即在半静态调度传输的子帧中,如果终端接收到动态调度,则接收或发送动态调度数据(基站将半静态调度的数据打包至动态调度的数据中)。
然而,当LTE系统动态调度和半静态调度对应的TTI不同时,由于同调度对应的数据到达时间、基站调度时间、数据处理时间不相同,导致现有的动态调度覆盖(override)半静态调度的工作机制将不再适用。
基于以上问题,本发明实施例提供了一种机制,以实现LTE系统中动态调度和半静态调度对应的TTI不同时的数据传输。
在本发明实施例中,时间单元可以为帧、子帧、时隙或符号。
优选地,时间单元可以为子帧。为了方便,本文以子帧为例进行说明,称目标时间单元为目标子帧。
图1示出了本发明实施例的传输数据的方法100,该方法100包括:
S110,终端接收基站发送的第一指示信令,该第一指示信令用于指示该终端在目标载波的目标时间单元上,使用第一时间间隔TTI传输半静态调度的第一数据。
S120,该终端接收该基站发送的第二指示信令,该第二指示信令用于指示该终端在该目标载波的该目标时间单元上,使用第二TTI传输动态调度的第二数据,其中,该第一TTI的长度和该第二TTI的长度不相等,并且该第一TTI的长度小于或等于时间单元的长度,该第二TTI的长度小于或等于时间单元的长度。
S130,该终端确定半静态调度传输占用的第一时间资源在该目标时间单元的位置和动态调度传输占用的第二时间资源在该目标时间单元的位置。
S140,该终端根据该第一时间资源在该目标时间单元中的位置和该第二时间资源在该目标时间单元中的位置,确定传输该第一数据和该第二数据中的至少一种。
其中,执行方法100的终端可以支持不同长度TTI的传输。半静态调度方面,基站向终端发送第一指示信令,该第一指示信令用于指示终端进行半静态调度。终端在半静态调度时,每隔固定的周期在相同的频率资源上进行数据传输。因此,终端是在位置固定的一些时频资源上进行半静态调度的数据的传输。本发明实施例中,这些固定的时频资源中的一个时频资源的频域对应目标载波,时域对应目标子帧。终端在目标载波的目标子帧上,使用第一TTI,占用目标子帧中的第一时间资源传输半静态调度的第一数据。优选地,该第一指示信令为DCI,该第一DCI中包括用于指示目标载波和目标子帧的信息。终端确定半静态调度传输占用的第一时间资源在目标子帧中的具体的位置。
动态调度方面,基站向终端发送第二指示信令,该第二指示信令用于指示该终端在该目标载波的该目标子帧上,使用第二TTI传输动态调度的第二数据。相应地,终端接收基站的该第二指示信令。优选地,该指示信令为DCI,该DCI中包括用于指示目标载波和目标子帧的信息。终端确定动态调度传输占用的第二时间资源在目标子帧中的位置。
其中,该第一TTI的长度和该第二TTI的长度不相等,并且该第一TTI的长度小于或等于时间单元(子帧)的长度,该第二TTI的长度小于或等于时间单元(子帧)的长度。
终端根据半静态调度的第一数据所占用的第一时间资源的在目标子帧中的位置,以及动态调度的第二数据所占用的第二时间资源的在目标子帧中的位置,控制第一数据和第二数据的传输。或者,换而言之,确定传输该第 一数据和该第二数据中的至少一种。
具体地,传输半静态调度的第一数据包括发送半静态调度(Semi-Persistent Scheduling,SPS)的第一物理上行共享信道(Physical Uplink Shared Channel,PUSCH),这里将半静态调度的第一PUSCH简称为SPS-PUSCH。传输动态调度的第二数据包括发送动态调度(dynamic scheduling)的第二PUSCH,这里将动态调度的第二PUSCH简称为dyn-PUSCH。
或者,另外一种情况,传输半静态调度的第一数据包括接收半静态调度的第一物理下行共享信道(Physical Downlink Shared Channel,PDSCH),这里将半静态调度的第一PDSCH简称为SPS-PDSCH。传输动态调度的第二数据包括接收动态调度的第二PDSCH,这里将动态调度的第二PDSCH简称为dyn-PDSCH。
本发明实施例的传输数据的方法,终端支持不同TTI的传输,基站指示终端在目标载波的目标时间单元上,使用第一TTI传输半静态调度的第一数据,使用第二TTI传输动态调度的第二数据,根据传输半静态调度占用的第一时间资源和传输动态调度占用的第二时间资源分别在目标时间单元中的位置,确定传输第一数据和该第二数据中的至少一种,从而实现不同TTI下的动态调度和半静态调度。
