具体实施方式
下文中将结合附图对本申请的实施例进行说明。
为了获取到高精度的信道状态信息，第二通信节点向第一通信节点发送上行探测参考信号(Sounding Reference Signal，SRS)，基站通过测量上行探测参考信号获取信道系数矩阵，以及到达角度与离开角度信息，多径时延信息；第一通信节点根据所获得的上行信道信息及上下行信道的互易性，估算下行信道的空域滤波器与频域预编码；然后发射信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)给终端；其中，每一端口的CSI-RS是通过空域滤波器与频域预编码码字加权生成，即每一端口的CSI-RS对应着一对(空域滤波器，频域预编码码字)；第二通信节点根据对CSI-RS的测量向第一通信节点上报信道状态信息。在实施例中，信道状态信息包括预编码矩阵信息。
一个空域滤波器，就是一组用在天线端口上的加权因子，以产生由多根天线发射的合成信号。空域滤波器可以分离出目标空域方向的信号，例如分离出目标波束方向的信号。一个频域预编码码字就是用在不同频域上的一组加权因子，以产生频域上不同加权的信号。多个频域预编码码字通过加权组成频域预编码，频域预编码中的元素作用在不同的频域上以产生频域上不同加权的信号。但这种获取信道状态信息的方法需分别匹配对应的探测参考信号、信道状态信息参考信号以及CSI报告，增加了传输复杂度，不方便使用。
本申请实施例提供一种信息获取方法，通过对应的信道状态信息参考信号资源，对应的探测参考信号资源从而联合上下行信道获取信道状态信息的报告，减轻了基站获取信道状态信息而匹配接收探测参考信号、发送信道状态信息参考信号、接收信道状态信息报告的复杂度，又减轻了终端发送信道状态信息报告而匹配发送探测参考信号、接收信道状态信息参考信号的复杂度。
在一实现方式中，图1是本申请实施例提供的一种信息获取方法的流程图。本实施例应用于第一通信节点。在一实施例中，第一通信节点可以为基站。如图1所示，本实施例包括S110-S140。
S110、确定CSI报告的第一配置信息。
在实施例中，第一配置信息包括：同时关联的CSI-RS资源和SRS资源；CSI-RS资源用于承载信道状态信息参考信号，SRS资源用于承载探测参考信号。
在实施例中，通过第一配置信息，CSI报告既关联CSI-RS资源，又关联SRS资源，使得第一通信节点可以便捷地接收对应的上行探测参考信号以及发射对应的信道状态信息参考信号，并且便捷地接收第二通信节点发送的对应的CSI报告。
S120、将第一配置信息发送至第二通信节点。
在实施例中，在第一通信节点确定CSI报告的第一配置信息之后，将既关联CSI-RS资源，又关联SRS资源的第一配置信息发送至第二通信节点，以使第二通信节点可以便捷地发送对应的上行探测参考信号以及接收对应的信道状态信息参考信号。
S130、接收第二通信节点反馈的CSI报告。
在实施例中，CSI报告是根据CSI-RS资源上承载的信道状态信息参考信号的测量而生成。在实施例中，在第二通信节点接收到CSI报告的第一配置信息之后，第二通信节点根据第一通信节点发射的信道状态信息参考信号，即CSI-RS资源上承载的信道状态信息参考信号的测量得到CSI报告。将CSI报告反馈至第一通信节点。
S140、根据CSI报告得到对应的信道状态信息。
在实施例中，第一通信节点对CSI报告中的信息进行解析，即可得到对应的信道状态信息。
在一实现方式中，第一通信节点接收第二通信节点发射的所关联的SRS资源所承载的上行探测参考信号，从上行探测参考信号中提取信道信息，根据上下行信道的互易性确定用于下行传输的空域滤波器及频域预编码码字，第一通信节点在CSI-RS资源上发射通过空域滤波器与频域预编码码字加权生成的信道状态信息参考信号，然后接收第二通信节点根据信道状态信息参考信号的测量而生成的CSI报告。
在一实施例中，在第一配置信息中关联CSI-RS资源的方式包括下述之一：关联CSI-RS资源的标识；关联CSI-RS资源所属集合的标识；在第一配置信息中关联SRS资源的方式包括下述之一：关联SRS资源的标识；关联SRS资源所属集 合的标识。
在一实现方式中，在第一配置信息中关联CSI-RS资源的标识，或者在第一配置信息中关联CSI-RS资源所属集合的标识。示例性地，可以在第一配置信息中描述被关联的CSI-RS资源的标识，或者描述被关联的CSI-RS资源所属集合的标识。
在一实施例中，在第一配置信息中关联SRS资源的标识，或者在第一配置信息中关联SRS资源所属集合的标识。示例性地，可以在第一配置信息中描述被关联的SRS资源的标识，或者描述被关联的SRS资源所属集合的标识。
在一实施例中，CSI-RS资源和SRS资源的关联位置包括下述之一：在第一配置信息的不同位置；在第一配置信息的同一位置；在第一配置信息的相邻位置。
在一实现方式中，在第一配置信息中既关联CSI-RS资源，又关联SRS资源，其方式可以是在第一配置信息的不同位置分别描述被关联的CSI-RS资源与SRS资源；也可以在第一配置信息的同一位置处一起描述被关联的CSI-RS资源与SRS资源；也可以在第一配置信息的相邻位置处分别描述被关联的CSI-RS资源和SRS资源。在第一配置信息中包括既关联CSI-RS资源的信息，又关联SRS资源的信息，可以通过对应的CSI-RS资源，和对应的SRS资源联合上下行信道获取信道状态信息的报告，减轻了第一通信节点获取信道状态信息而分别匹配接收探测参考信号、发送信道状态信息参考信号和接收信道状态信息的复杂度。在一实施例中，在第一配置信息的不同位置，可以为第一配置信息的不同行、不同页等；在第一配置信息的同一位置处，可以为第一配置信息的同一行或同一页等；在第一配置信息的相邻位置处，可以为第一配置信息的相邻两行，或相邻两页等，对此并不进行限定。
在一实现方式中，在一些场景下，信道状态信息报告的传输、信道状态信息参考信号的传输、上行探测参考信号的传输是持续进行。在一些场景下，信道状态信息报告的传输、信道状态信息参考信号的传输、上行探测参考信号的传输不是持续进行。对于这些传输不是持续进行的场景，通知信道状态信息报告的传输的一个解决方案就是使用信令进行触发，例如使用下行控制信息格式信令进行触发。
在一实施例中，在CSI报告、信道状态信息参考信号和探测参考信号非持续 传输的情况下，信息获取方法，还包括：采用下行控制信息(Downlink Control Information，DCI)格式信令同时触发下述至少两种事件：第一通信节点接收探测参考信号；第一通信节点发射信道状态信息参考信号；第一通信节点接收CSI报告。
在一实施例中，第一通信节点可以采用一次DCI格式信令同时触发下述任意两种事件：第一通信节点接收探测参考信号；第一通信节点发射信道状态信息参考信号；第一通信节点接收CSI报告。在一实施例中，第一通信节点采用一次DCI格式信令同时触发下述事件：第一通信节点接收探测参考信号；第一通信节点发射信道状态信息参考信号；第一通信节点接收CSI报告。在实施例中，这三个事件的执行顺序可以为：第一通信节点接收探测参考信号，第一通信节点发射信道状态信息参考信号，第一通信节点接收CSI报告。
在实施例中，仅采用一次DCI格式信令就触发了三个有关联的事件，即信道状态信息获取的完整事件过程，也就是一次DCI格式信令就促成了信道状态信息获取中各事件的进行，完成了信道状态信息的获取，从而比分别使用信令触发每一个事件节省了信令开销，节省了第一通信节点使用信令的次数，也节省了第二通信节点接收信令的次数。
在一实现方式中，第一通信节点使用一次DCI格式信令同时触发上述三个事件的方式。在一实施例中，在DCI格式信令中分别描述探测参考信号、信道状态信息参考信号、信道状态信息报告，或者分别描述测参考信号的标识、信道状态信息参考信号的标识、信道状态信息报告的标识。
在一实施例中，DCI格式信令包括下述至少之一：探测参考信号；信道状态信息参考信号；CSI报告。
在一实施例中，DCI格式信令包括下述至少之一：探测参考信号的标识；信道状态信息参考信号的标识；CSI报告的标识。
在一实现方式中，CSI报告的第一配置信息包括一同关联CSI-RS资源和SRS资源，即在DCI格式信令中仅指示其中之一，即可同时触发所述的三个事件(第一通信节点接收探测参考信号；第一通信节点发射信道状态信息参考信号；第一通信节点接收CSI报告)，可以减轻DCI格式信令包括的指示信息负荷，减轻DCI格式信令的复杂度。
在一实现方式中，第一通信节点采用DCI格式信令同时触发第一通信节点接收探测参考信号；第一通信节点发射信道状态信息参考信号；第一通信节点接收CSI报告这三个事件。示例性地，第一通信节点在DCI格式信令中指示CSI报告的标识，对应地CSI报告的标识指示的CSI报告、与CSI报告相关联的信道状态信息参考信号和探测参考信号被触发。在实施例中，根据DCI格式信令指示出的CSI报告的标识，可以方便地从CSI报告的第一配置信息读取与CSI报告相关联的信道状态信息参考信号、探测参考信号信息的描述，从而在触发CSI报告的同时，便捷地触发对应的信道状态信息参考信号、探测参考信号。
在一实施例中，第一配置信息，还包括：频域预编码矢量的尺寸，以及与频域预编码矢量的尺寸对应的带宽；第一配置信息中的CSI-RS资源的密度是第一比值的整数倍，第一比值为频域预编码矢量的尺寸与频域预编码矢量的尺寸对应的带宽之间的比值；频域预编码矢量的尺寸为频域预编码矢量中包含元素的数量；CSI-RS资源的密度为每个资源块(Resource Block，RB)上，每个端口平均占用资源单元(Resource Element，RE)的数目。
在一实现方式中，在频域预编码以矢量形式描述的情况下，称为频域预编码矢量；频域预编码矢量的尺寸就是频域预编码矢量中包含元素的数量。频域预编码矢量可以分析到一组正交的频域预编码码字上，即频域预编码矢量可以表现为一组正交的频域预编码码字的线性组合。报告信道状态信息的一个方案是报告所述线性组合中频域预编码码字的权值，所述权值基于对频域预编码矢量的尺寸所对应的带宽内的整数倍频域预编码矢量的尺寸的信道状态信息参考信号对应的信道系数的测量，即第一配置信息还包括：频域预编码矢量的尺寸及与频域预编码矢量的尺寸对应的带宽，并且第一配置信息中的信道状态信息参考信号资源的密度是第一比值的整数倍，可以便利支持对信道状态信息进行报告的方案。信道状态信息参考信号资源的密度是第一比值的整数倍，其中信道状态信息参考信号资源的密度是每RB每端口平均占用RE的数目；第一比值是频域预编码矢量的尺寸与频域预编码矢量的尺寸对应的带宽的比值，其中带宽是转化为以RB为单位计算的数目。
在一实施例中，CSI-RS资源上的两个维度与CSI报告中预编码矩阵的两个维度之间存在对应关系；CSI-RS资源上的两个维度包括：码分复用组，码分复用组上每个端口进行码分复用所使用的码序列；CSI报告中预编码矩阵的两个维度 包括：空域波束矢量，频域预编码码字。
在一实现方式中，信道状态信息参考信号资源由资源单元组组成，资源单元组由一定数量的资源单元构成，即资源单元组是一定数量的资源单元的集合，信道状态信息参考信号的端口以码分复用的方式承载于资源单元组上，这样的资源单元组就是一个码分复用组(Code Division Multiplexing group，CDM group)。每个码分复用组承载一定数量的信道状态信息参考信号的端口；在相同CDM group中的端口通过不同的码序列复用在这个CDM group上；也就是信道状态信息参考信号资源有两个维度，一个维度是CDM group，另一个维度是CDM group上各端口进行码分复用所使用的码序列。
预编码矩阵可以解析为空域波束矢量下的频域预编码码字的线性组合；也就是预编码矩阵对应两个维度，一个维度是空域波束矢量，也表现为空域滤波器，另一个维度是频域预编码码字。报告信道状态信息的一个方案是报告所述线性组合中与这两个维度对应的预编码码字的权值。
建立参考信号资源上的两个维度与预编码矩阵的两个维度之间的对应关系，就是把参考信号方面的维度与预编码矩阵方面的维度匹配起来，即把用于测量的信号方面的维度与用于报告方面的维度关联起来，从而把CSI报告中数个第一维度组合(即空域波束矢量和频域预编码码字)便捷地与信道状态信息参考信号端口关联起来，使得数个第一维度组合(即空域波束矢量和频域预编码码字)便捷地与信道状态信息参考信号端口之间的查找变得简便，减小了第一通信节点的复杂度，也减小了第二通信节点的复杂度。
在一实施例中，码分复用组与空域波束矢量相对应；信道状态信息参考信号的端口使用的码序列与频域预编码码字相对应。
在实施例中，码分复用组与空域波束矢量相对应；信道状态信息参考信号的端口使用的码序列与频域预编码码字相对应的实现方式可以包括下述四种：
方式一，承载于相同CDM group中的端口对应相同的空域波束矢量。
方式二，使用相同码序列的端口对应相同的频域预编码码字。
方式三，使用相同码序列而承载于不同CDM group的端口对应不同的空域波束矢量。
方式四，承载于相同CDM group而使用不同码序列的端口对应不同的频域预 编码码字。
在一实施例中，码分复用组与频域预编码码字相对应；信道状态信息参考信号的端口使用的码序列与空域波束矢量相对应。
在实施例中，码分复用组与频域预编码码字相对应；信道状态信息参考信号的端口使用的码序列与空域波束矢量相对应的实现方式可以包括下述四种：
方式一，承载于相同CDM group中的端口对应相同的频域预编码码字。
方式二，使用相同码序列的端口对应相同的空域波束矢量。
方式三，使用相同码序列而承载于不同CDM group的端口对应不同的频域预编码码字。
方式四，承载于相同CDM group而使用不同码序列的端口对应不同的空域波束矢量。
在一实施例中，CSI-RS资源与CSI报告中的信息存在下述对应关系之一：信道状态信息参考信号的端口与预编码矩阵的第一维度组合相对应；预编码矩阵的第一维度组合包括：空域波束矢量和频域预编码码字；信道状态信息参考信号的M个端口与预编码矩阵的第一维度组合相对应，M为正整数；一个码分复用组上的所有信道状态信息参考信号的端口与预编码矩阵的第一维度组合相对应。
在一实施例中，信道状态信息参考信号的一个端口可以通过一个第一维度组合(即空域波束矢量和频域预编码码字)产生。信道状态信息参考信号的端口与第一维度组合一一对应，从CSI报告中的第一维度组合可以便捷映射到具体的信道状态信息参考信号的端口上所使用的空域波束矢量与频域预编码码字。在一实施例中，信道状态信息参考信号的M个端口对应一个第一维度组合(即空域波束矢量，频域预编码码字)，M为可配置的正整数。在一实施例中，可以使用多个端口测量同一个第一维度组合(即空域波束矢量，频域预编码码字)，使得测量更为精度；同时M为可配置的正整数，使得可以根据场景来配置M，使得测量的精度与场景相匹配。一个CDM group上的所有信道状态信息参考信号的端口对应一个第一维度组合(空域波束矢量，频域预编码码字)，其中同一个CDM group上的端口因为使用的时频资源相同，经历的信道相同，从而在测量第一维度组合(空域波束矢量，频域预编码码字)时不会因为信道差异带来测量误差，可以提高测 量的精度。
在一实施例中，CSI报告对应的带宽是频域预编码矢量的尺寸对应带宽的整数倍，CSI报告对应的带宽为所报告的信道状态信息的带宽。
在实施例中，CSI报告所对应的带宽就是所报告的信道状态信息的带宽，也就是信道状态信息描述的是这个带宽上的信道的信息。CSI报告所对应的带宽是频域预编码矢量的尺寸对应的带宽的整数倍，可以方便在这个带宽内提供正交的频域预编码矢量或正交的频域预编码码字；也就是可以在这个带宽内方便地将正交的频域预编码码字用于信道状态信息参考信号端口。示例性地，CSI报告所对应的带宽刚好与频域预编码矢量的尺寸对应的带宽相同。示例性地，信道状态信息报告所对应的带宽刚好是频域预编码矢量的尺寸对应的带宽的2倍。
在一实现方式中，图2是本申请实施例提供的另一种信息获取方法的流程图。本实施例应用于第二通信节点。在一实施例中，第二通信节点可以为用户终端。如图2所示，本实施例包括S210-S220。

在实施例中，第一配置信息包括：同时关联的CSI-RS资源和SRS资源；CSI-RS资源用于承载信道状态信息参考信号，SRS资源用于承载探测参考信号。
S220、向第一通信节点反馈CSI报告。
在实施例中，CSI报告是根据CSI-RS资源上承载的信道状态信息参考信号的测量而生成，CSI报告用于使第一通信节点解析得到对应的信道状态信息。
在实施例中，第一通信节点通过在CSI报告的第一配置信息中关联对应的CSI-RS资源与SRS资源，使得第二通信节点可以便捷地发送对应的上行探测参考信号及接收对应的信道状态信息参考信号；同时也使得基站可以便捷地接收对应的上行探测参考信号及发射对应的信道状态信息参考信号，并且便捷地接收终端发送的对应的信道状态信息报告，从而减轻了第二通信节点发送信道状态信息报告而匹配发送探测参考信号以及接收信道状态信息参考信号的复杂度。
在一实施例中，第二通信节点可以采用一次DCI格式信令同时触发下述事件：第二通信节点发送探测参考信号；第二通信节点接收信道状态信息参考信号；第二通信节点发送CSI报告。在一实施例中，第二通信节点可以采用一次DCI格式信令同时触发下述两种事件：第二通信节点发送探测参考信号；第二通信 节点接收信道状态信息参考信号；第二通信节点发送CSI报告。在实施例中，第二通信节点仅采用一次DCI格式信令可以触发三个关联的事件，即将信道状态信息发送至第一通信节点的过程，从而比采用信令分别触发每一个事件节省了信令开销，即节省了第二通信节点接收信令的次数。
