本申请基于申请号为201711080687.4、申请日为2017年11月06日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的内容在此以引入方式并入本申请。
技术领域
本发明涉及通信领域，具体而言，涉及一种索引获取方法及装置。
背景技术
在第四代移动通信技术(the 4th Generation mobile communication technology，简称为4G)高级长期演进(Long-Term Evolution Advance简称为LTE-Advance或LTE-A)R10中为了进一步提高小区平均的频谱利用率和小区边缘频谱利用率以及各个UE的吞吐率，分别定义了两种参考信号：信道信息参考信号(Channel State Information-Reference Signal，简称为CSI-RS)和解调参考信号(Demodulation Reference Signal，简称为DMRS)。其中，CSI-RS用于信道的测量，通过对CSI-RS的测量可以计算出UE需要向eNB反馈的信道状态信息(Channel State Information，简称为CSI)。利用DMRS可以使得UE透明的接收下行数据，而无需知道基站侧适用的预编码权值，这样可以减少PDCCH负载的同时，可以减少码本对权值的限制。
随着对第五代移动通信技术(the 5th Generation mobile communication technology，简称为5G)的深入研究。业内普遍认为，5G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。为了达到超低时延的需求，一种有效实现超低时延的方法是通过减少LTE系统的发送时间间隔 (Transmission Time Interval，简称TTI)，从而成倍降低单向链路时延。其中，TTI是下行和上行传输调度在时域上的基本单位。随着TTI长度的缩短，下行解调导频图样和位置都会发生变化。那么就会出现在新的DMRS图样下，一些CSI-RS配置索引会出现不可用的情况。因此，当用户终端(User Equipment，简称为UE)仍按照LTE R10的CSI-RS配置索引进行CSI(信道状态)估计，就会出现信道估计偏差，从而恶化系统性能。
发明内容
本发明实施例提供了一种索引获取方法、装置及存储介质和处理器，以至少解决相关技术中TTI长度的发生变化后，CSI估计出现信道估计偏差的问题。
根据本发明的一个实施例，提供了一种索引获取方法，包括：获取传输时间间隔TTI发生变化后的下行解调参考信号图样；根据所述下行解调参考信号图样以及所述下行解调参考信号图样对应的信道状态信息参考信号配置索引的集合，获取用于信道估计的信道状态信息参考信号的配置索引。
根据本发明的另一个实施例，还提供了一种索引获取装置，包括：第一获取模块，配置为获取传输时间间隔TTI发生变化后的下行解调参考信号图样；第二获取模块，配置为根据所述下行解调参考信号图样以及所述下行解调参考信号图样对应的信道状态信息参考信号配置索引的集合，获取用于信道估计的信道状态信息参考信号的配置索引。
根据本发明的又一个实施例，还提供了一种存储介质，所述存储介质包括存储的程序，其中，所述程序运行时执行上述任一项所述的索引获取的方法。
根据本发明的又一个实施例，还提供了一种处理器，所述处理器用于运行程序，其中，所述程序运行时执行上述任一项所述的索引获取的方法。
通过本发明实施例，获取传输时间间隔TTI发生变化后的下行解调参考信号图样；根据下行解调参考信号图样以及下行解调参考信号图样对应的信道状态信息参考信号配置索引的集合，获取用于信道估计的信道状态信息参考信号的配置索引。其中，由于用于信道估计的在信道状态信息参考信号的配置索引，是在传输时间间隔TTI发生变化后的下行解调参考信号图样对应的可用的信道状态信息参考信号配置索引的集合中获取到，即，当TTI长度的发生变化后，采用指定的下行解调参考信号图样时，用于信道估计的信道状态信息参考信号的配置索引只能属于可用的指定集合，使得UE不再按照LTE R10的CSI-RS配置索引进行CSI估计，避免了信道估计不准确，影响系统性能的不足。因此，可以解决相关技术中TTI长度的发生变化后，CSI估计出现信道估计偏差的问题，达到优化系统性能效果。

此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：

需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
随着TTI长度缩短，考虑到数据传输速率的效率，需要对LTE DL(下行)DMRS(解调参考信号)图样进行重新设计，那么势必会出现DMRS时频域位置与CSI-RS时频域位置重叠，从而导致一些CSI-RS配置索引不 可用。本发明实施例中在预定的DMRS图样时，通过相关可用CSI-RS的配置索引集合获取CSI-RS可用的配置索引，来指导UE完成CSI-RS信道估计，能够有效避免对CSI-RS配置索引理解错误的发生。

为了详细描述上述实施例，下面结合附图以不同DMRS图样下，不同端口的哪些CSI-RS配置索引可用为例，在实施例一的基础上，实施例二至三十二中详细给出可用的CSI-RS配置索引的集合。
当TTI长度的发生变化后，且下行解调参考信号图样通常为指定的，这种情况下，用于信道估计的信道状态信息参考信号的配置索引能够从可用的指定集合(CSI-RS配置索引的集合)中得到，使得UE不再按照LTE R10的CSI-RS配置索引进行CSI估计，避免了信道估计不准确，影响系统性能的不足。因此，可以解决相关技术中TTI长度的发生变化后，CSI估计出现信道估计偏差的问题，达到优化系统性能效果。
需要说明的是，实施例二至三十二中都是以短传输时间间隔(sTTI)，并且sTTI时域长度为2个OFDM(正交频分复用)传输符号或者3个传输符号为例进行说明的。并且具体的1ms子帧的sTTI划分如图3所示。当控制格式指示(CFI)是1或者3时，1ms子帧的sTTI划分如图3(a)所示，sTTI#0～sTTI#5＝{3,2,2,2,2,3}符号；当CFI是2时，1ms子帧的sTTI划分如图3(b)所示，sTTI#0～sTTI#5＝{2,3,2,2,2,3}符号。
实施例二
本实施例给出在一个载波上，如图3所示的1ms子帧的sTTI划分格式中，当用户设备在sTTI#2、sTTI#4以及sTTI#5都使用如图4所示的DMRS图样1(a)时，并且1/2端口(相当于上述1个天线配置端口或者2个天线配置端口)的CSI-RS也在sTTI#2、sTTI#4以及sTTI#5上发送，那么就会出现与部分DMRS占据的RE发生冲突，从而导致不可用。所以我们结合DMRS图样以及sTTI具体格式，给出可配置的CSI-RS索引集合是{0、1、2、3、4、8、10、12、14、16、17、18}。
或者，当用户设备在sTTI#2、sTTI#4以及sTTI#5都使用如图4所示的DMRS图样1(a)时，并且4端口(相当于上述4个天线配置端口)的CSI-RS也在sTTI#2、sTTI#4以及sTTI#5上发送，给出可配置的CSI-RS索引集合是{0、1、2、3、4、8}。
实施例三
本实施例给出在一个载波上，如图3所示的1ms子帧的sTTI划分格式中，当用户设备在sTTI#2、sTTI#4以及sTTI#5使用如图4所示的DMRS图样1(b)时，并且1/2端口的CSI-RS也在sTTI#2、sTTI#4以及sTTI#5上发送，那么就会与出现部分DMRS占据的RE发生冲突，从而导致不可用。所以我们结合DMRS图样以及sTTI具体格式，给出可配置的CSI-RS索引集合是{0、2、3、4、6、8、12、13、16、17}。
