  • the present application relates to the field of wireless communication technology, and in particular to an information transmission method, electronic device and storage medium.
  • Multi-antenna technology is a key physical layer technology of 4G wireless communication system, namely Multiple Input Multiple Output (MIMO).
  • MIMO Multiple Input Multiple Output
  • the resource utilization efficiency in the spatial dimension can be significantly improved, thereby increasing the capacity of the wireless communication system.
  • the scale of antenna arrays has further increased, namely massive MIMO, for example, from 64 antennas to 192 antennas, and even to 1024 antennas in high frequency bands.
  • the number of antennas on the base station side may increase further.
  • the required pilot signal is proportional to the number of antennas. For example, the number of non-precoded pilot signals is generally consistent with the number of antenna ports, and the number of orthogonal beams corresponding to the precoded pilots is generally also required to be consistent with the number of antenna ports.
  • the time-frequency overhead required to send the pilot signal may offset the signal gain and spatial multiplexing gain brought by the large-scale array, which will restrict the further increase of the antenna array size. How to compress the number of pilot signals without affecting the accuracy of channel estimation is a key issue that needs to be paid attention to in future wireless communication technologies.
  • the current 5G physical layer standard protocol defines some entities related to airspace resource utilization, such as antenna ports, resources, resource sets, beams, transceiver nodes, antenna panels, etc., each with different levels of abstraction. On this basis, the protocol also implicitly defines some reference signal sending strategies and specifies the corresponding channel information measurement feedback method. In practical applications, the 5G protocol does not limit how the entity sends the measurement reference signal, leaving room for flexible operations on the network side. For example, wireless base stations can obtain some a priori environmental information in some scenarios. Based on this a priori information, the base station can selectively send a part of the pilot signal to compress the pilot overhead.
  • the terminal can pre-process the received pilot signal according to the dimensions of the base station antenna to obtain channel information that matches the dimensions of the base station side array.

  • the channel information estimated based on this has a large error and does not match the antenna array dimensions on the base station side. Therefore, a new configuration method needs to be considered to support channel estimation and feedback under the condition of on-demand pilot transmission.

一种信息传输方法、电子设备和存储介质
相关申请的交叉引用
本申请要求在2023年11月30日提交中国专利局、申请号为202311641051.8、发明名称为“一种信息传输方法、电子设备和存储介质”的中国专利申请的优先权，该中国专利申请的全部内容通过引用包含于此。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种信息传输方法、电子设备和存储介质。
背景技术
多天线技术是4G无线通信系统的关键物理层技术，即多输入多输出技术(Multiple Input Multiple Output,MIMO)，通过使用天线阵列发射和接收无线信号，可以显著提升空间维度的资源利用效率，进而提升无线通信系统的容量。进入5G通信时代，天线阵列的规模进一步增大，即massive MIMO，例如由64天线增加到192天线，甚至在高频段可以增加到1024天线。未来无线通信系统中，基站侧天线的数量还可能进一步增加。为了充分发挥MIMO阵列的性能，需要利用参考信号(Reference Signal)或导频对基站和终端之间的信道进行估计，根据信道估计结果确定最佳的阵列预编码用于阵列信号的发射。天线阵列的规模越大，导频开销也越大。一般而言，为了准确地估计出信道信息，所需的导频信号正比于天线数量。例如，非预编码导频信号的个数一般和天线端口数一致，而预编码导频对应的正交波束个数一般也需要和天线端口数量一致。因此，当阵列规模大到一定程度时，发送导频信号所需的时频开销可能会抵消大规模阵列带来的信号增益空间复用增益，这将制约天线阵列规模的进一步增大。如何压缩导频信号的数量而不影响信道估计的精度是未来无线通信技术需要关注的一个重点问题。
目前5G物理层标准协议定义了空域资源利用相关的一些实体，如天线端口、资源、资源集、波束、收发节点、天线面板等，分别有不同的抽象级别。协议在此基础上还隐式地定义了一些参考信号的发送策略，并规定了对应的信道信息测量反馈方法。在实际应用中，5G协议并不限定实体会如何发送测量参考信号，给予了实现网络侧灵活操作的空间。例如，无线基站在一些场景中可以获得部分先验的环境信息，根据这些先验信息，基站可以有选择的发送一部分导频信号，以压缩导频开销。理论上，终端可以根据基站天线的维度，对接收的导频信号进行预处理，获得与基站侧阵列的维度匹配的信道信息。然而，相 关的通信标准并不支持相应的配置流程，终端并不清楚基站侧是在哪个类型的实体上发射的参考信号，因此接收到参考信号之后一般默认获取的是一组完整的非预编码导频信号或者一组完备的正交预编码导频信号，据此估计的信道信息存在较大误差且与基站侧的天线阵列维度不匹配。因此，需要考虑一种新的配置方式，以支持按需导频发射条件下的信道估计和反馈。
发明内容
本申请实施例旨在提供一种信息传输方法、电子设备和存储介质，以实现信道状态信息的获取，压缩导频开销，提升信道信息估计的准确性，提升信道状态信息与基站天线阵列维度的匹配程度，可提高通信质量。

具体实施方式
应当理解，此处所描述的具体实施仅仅用以解释本申请，并用于限定本申请。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”后缀仅为了有利于本申请的说明，其本身没有特有的意义，因此，“模块”、“部件”或“单元”可以混合地使用。
图1是本申请实施例提供的一种信息传输方法的流程图，本申请实施例可适用于大规模阵列天线情况下的信道状态信息估计配置的情况，该方法可以由信息传输装置来执行，该装置可以通过软件和/或硬件的方法实现，并一般集成在反馈端，例如，反馈端可以是包括移动终端、物联网设备终端、车载终端等，参见图1，本申请实施例提供的方法包括如下步骤：步骤110、接收用于信道测量的参考信号。

在一些申请实施例中，信道量化指示信息包括以下至少之一：预编码信息、波束选择信息、传输层数或信道秩的信息、测量参考信号选择信息、波束质量信息、测量参考信号资源或端口选择信息。
图3是本申请实施例提供的一种信息传输方法的示例图，以基站与终端之间的信道状态信息测量的配置为例，基站与终端之间的信息传输可以包括如下过程：步骤301：基站从完整的参考信号集合中选择一个子集，该参考信号包括但不限于信道状态信息参考信号CSI-RS、同步信号SS。步骤302：基站利用时频域发射所选参考信号子集中的参考信号 用于信道测量。步骤303：终端测量用于信道测量的参考信号，获得参考信号测量矢量。步骤304：基站与终端约定参考信号接收方式，或者，网络侧发送信令以配置参考信号接收方式。其中，接收方式可以包括接收端在接收参考信号是按照指定预处理方式对参考信号测量矢量进行预处理。步骤305：终端根据配置的参考信号接收方式对接收到参考信号生产的参考信号测量矢量进行预处理。步骤306：终端根据预处理后的参考信号测量矢量中的测量结果进行信道估计并向基站反馈信道信息，其中，该信道信息可以是与当前估计的信道信息匹配的预编码码本的指示信息，也可以是对应端口选择码本中的端口指示信息，或者，还可以是波束的索引信息。
在本申请实施例中，参见图3，基站与终端之间的信息传输可以通过选择参考信号集合发射、接收参考信号、测量结果预处理、信道估计和反馈等过程组成，参考信号可以是现有标准协议内定义的多种类型的参考信号，该参考信号可以用于信道测量，参考信号可以包括非预编码参考信号、预编码参考信号等，不同类型的参考信号绑定的天线实体不同，相应的反馈信息也不同。基站侧在信道估计阶段可以选择合适的参考信号类型用于信道测量。对于每一种类型的参考信号，现有标准协议一般预设了完备的参考信号集合。完备，可以理解为参考信号集合的维度与基站天线端口数量匹配。例如，对于非预编码参考信号，基站可以在每个天线端口发射参考信号，因此参考信号集合的维度与天线端口数量一致。又例如，对于预编码参考信号，参考信号承载于与天线端口数量一致的正交波束之上。如果基站侧天线规模非常大，则完备的参考信号集合的维度也非常大，信道估计过程需要占用非常多的时频资源。因此，基站可以在完备的参考信号集合中选择一个子集用于信道估计。基站选择参考信号子集的依据可以包括先验的环境信息、终端的位置信息等，其中先验的环境信息可以包括由感知技术等确定的信道信息、终端的历史反馈信息等。
基站确定参考信号子集之后将该子集置于预设的时频资源上通过天线阵列发射。对于非预编码参考信号，可以按照参考信号的序号置于不同的时隙和子带资源块内发射。对于预编码参考信号，则可以按照一定的空间方位顺序发射。
终端接收基站发射的参考信号。一般而言，终端会根据信道估计配置信息和同步信息在指定的信道上监听和接收参考信号。
终端根据确定的预处理方式对接收的参考信号进行处理。预处理方式至少包括修改至少一个参考信号的测量值、增大参考信号测量矢量的维度。例如，将预设位置的测量值修改为预设的固定值；又例如，在预设的位置插入预设值。
终端利用预处理后的参考信号测量矢量进行信道估计并进行量化反馈。反馈方式可以包括波束选择、码本反馈等；信道信息包括预编码信息、波束选择信息、层数或秩的信 息、测量参考信号选择信息、波束质量信息、测量参考信号资源或端口选择信息等等。
在上述申请实施例的基础上，终端对参考信号测量结果的预处理方式可以包括以下方式：1、对测量数据进行插值预处理
在一些申请实施例中，为了节约参考信号开销，可以利用已知的部分信道信息压缩参考信号的数量，此时接收端(反馈端)接收到的测量结果的维度小于信道H的维度，例如，在一个参考信号发射过程中，基站共发射了r个参考信号，因此终端只接收到r个参考信号的测量值，记为y＝[y1,y2,...,yr]，而信道H的维度为N，其中N大于r。此时可以通过插值将y矢量的维度增大到N，以匹配H的维度。插值方式包括如下几类：(1)插入固定值
可以在对应参考信号的测量矢量中插入固定值，该固定值可以是零值，在接收到的y矢量中通过补零操作增大其维度以匹配H的维度。例如在元素y1之前插入N-r个零值，又例如在元素yr之后插入N-r个零值，使y矢量的长度也变为N。此外，还可以在y矢量的多个元素之间插入零值，使y矢量的长度变为N。如图4所示，原始测量矢量的长度为8，即基站侧实际只发射了8个参考信号，而基站侧实际是信道维度为12，则需要将测量矢量的维度也增大到12，图4中预处理矢量1、2、3就是通过插值预处理后，将参考信号测量矢量的长度变为了12，其中扩展位置上采用了补零操作。
测量矢量y中的插值位置可以由基站侧下发配置信令进行配置。其中，插值位置可以根据基站发送的参考信号集合的指示信息进行配置，该指示信息可以指示基站所选择的参考信号集合或者未选择的参考信号集合。插值位置还可以由基站与终端之间预先约定。
可以理解的是，除了插入零值外，也可以考虑采用其他的预设值(例如1或者-1等)作为插入值。也可以是预设的一组数值集合，在不同的插值位置可以从该集合中选择一个数值进行插值。以上用于扩展y矢量维度的固定值可以由基站下发配置信令进行配置，也可以预先约定。
(2)利用插值算法进行插值
在另一些申请实施例中，多个参考信号之间具有一定的相关性，因此在扩展y矢量维度的预处理中可以考虑采用插值算法确定预设插值位置的数值。
例如，可以采用周期延拓方法确定在y1元素之前的N-r个插入元素的值，该周期延拓方法也可以用于在yr元素之后的插值。
又例如，可以采用线性插值的方式确定y矢量中两个相邻元素之间的插值。一种简单的线性插值是以插值位置两侧的两个元素的均值插入该位置，同理也可以是以插值位置附近的多个元素的均值作为插入值。如图5所示，原始的参考信号测量矢量维度为8，终端 在预处理中分别在第二、三个测量值之间插入了两个值，在第四、五个测量值之间插入另一个值，在第五、六个测量值之间插入一个值，插入的数值均为该位置两侧测量值的平均值。
又例如，可以采用非线性插值方法确定指定位置上插入的数值，一种典型的确定插入的数值的方法是最小二乘拟合方法，另外也可以采用样条插值等算法来确定。
2、对测量数据的数值进行替换预处理
由于一些通信场景中存在干扰信号，使得终端接收到的一部分参考信号受到干扰，信道估计的精度会受到一定的影响，如果能预先剔除收到干扰的数据，则可以提升信道估计的可靠性。
在一些申请实施例中，一种剔除干扰的预处理方式是将y矢量中的部分元素置零，即忽略这部分参考信号对信道估计的贡献。如图6所示，接收矢量y中包含8个参考信号的接收数据y1、y2、...、y8，测量结果中这8个测量值都是非零值，如果终端确定其中y3和y7两个测量值存在干扰信号，则可以将y矢量中相应位置的值改为零值，从而消除干扰的影响。除了将携带干扰成分的测量值置为零值之外，也可以设置为其他合适的固定值。
在另一些申请实施例中，另一种剔除干扰的预处理方式是将待剔除的数据用插值算法确定的数值替代，例如前述y3和y7可以替换为由插值算法确定的数值，插值算法可以选择前述的各种插值算法之一，如图7所示。
在上述申请实施例的基础上，数值替换的位置可以由终端根据信号处理算法确定，例如一些干扰感知算法，也可以由基站通过信令配置。一般而言，干扰抑制的预处理需要基站和终端中至少一方已知干扰信息才能有效执行。
3、对测量数据同时执行数值替换和插值预处理
在一些场景中，需要对接收到的测量矢量y同时执行数值替换和插值两类预处理。例如，y的维度和信道H的维度不匹配，同时y中还包含干扰信息。
此时，可以考虑先对存在干扰的测量数据进行数值替换，剔除干扰，再通过插值预处理扩展y的维度，以匹配H的维度。数值替换以及插值的方式可以采用上述申请实施例提供的方式。
