Abstract

Description

参数发送和接收的方法、装置和通信系统 技术领域
本申请实施例涉及通信技术领域。
背景技术
大规模多输入多输出(MIMO,multiple-input multiple-output)技术是5G移动通信的关键技术之一。MIMO能够提供更高的信道容量，但是这些好处的获得取决于能否获取准确的信道状态信息。
在频分双工(FDD)系统中，对于下行链路而言，网络设备在利用下行信道的信息来进行预编码时，需要终端设备通过上行链路将下行信道状态信息反馈给网络设备。但是由于下行信道的信息和网络设备的天线数目是成正比的，在大规模MIMO的场景下，巨大的网络设备天线数会导致下行信道的信道状态信息反馈量非常巨大，第三代伙伴计划(3GPP)针对下行反馈设计了增强型的码书(例如，etype II码书)，通过频域压缩来降低信道状态信息(CSI，Channel State Information)的反馈量，但是对于宝贵的上行资源来说，上行反馈量还有进一步减少的需求。
伴随着人工智能(AI，Artificial Intelligence)技术的发展，将人工智能技术应用到无线通信物理层上，来解决传统方法的难点成为当前一个技术方向。对于CSI反馈而言，利用经典的编译码AI模型，在终端侧通过编码器对下行信道状态信息进行压缩，网络设备通过空口接收压缩后的信道状态信息，再进行解压缩恢复信道状态信息。由于在空口传输的是压缩后的信道状态信息，在信道系数相关性比较好的情况下，能够大幅度减少上行信道的反馈量。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在编译码器对M*N维(即，发射天线端口为M个，接收天线端口为N个)的 CSI信道矩阵进行压缩和解压缩时，网络设备和终端设备都需要知道信道矩阵的维度。其中，网络设备知道自身的发射天线端口数目和配置模式，终端设备也知道自身的接收天线的端口数目和配置模式。此外，根据3GPP协议，网络设备会通过信令将发射天线端口数目及配置模式通知给终端设备。
本申请的发明人发现，在现有技术中，网络设备并不知晓终端设备的接收天线的参数，因此，难以训练或选择用于CSI编译码的模型。
针对上述问题，本申请实施例提供一种参数接收和发送的方法、装置和通信系统，终端设备将接收天线的参数发送给网络设备，由此，网络设备能够对CSI编译码的模型进行训练或选择。
根据本申请实施例的一个方面，提供一种参数发送的装置，应用于终端设备，所述装置包括：
第一接收单元，其接收请求信息，所述请求信息用于指示所述终端设备发送接收天线的参数；以及
第一发送单元，其发送所述终端设备的所述接收天线的参数。
根据本申请实施例的另一个方面，提供一种参数接收的装置，应用于网络设备，所述装置包括：
第二发送单元，其发送请求信息，所述请求信息用于指示终端设备发送接收天线的参数；以及
第二接收单元，其接收所述终端设备的所述接收天线的参数。
本申请实施例的有益效果之一在于：终端设备将接收天线的参数发送给网络设备，由此，网络设备能够对CSI编译码的模型进行训练或选择。

此外，图4中的发射链路401和接收链路402的数目是相等的，但本申请不限于此，例如，在某些收发单元中可以没有发射链路或者接收链路，或者，在某些收发单元中的发射链路或者接收链路可以不工作。本申请所描述的接收端口的数目可以指工作的接收链路的数目。
在至少另一个实施例中，接收天线的端口可以是多个接收天线阵元的等效接收天线。
图5是等效接收天线的一个示意图。如图5所示，一个射频单元50上可以连接有L个接收天线阵元，但是，该L个接收天线阵元只对应一个接收链路，因此，连接于同一个射频单元50上的该L个接收天线阵元可以被视为一个等效接收天线，即，一个接收天线的端口。
在第一方面的实施例中，接收天线的类型可以是全向天线、定向天线和交叉极化天线中的至少一者。
在第一方面的实施例中，接收天线的阵列配置可以包括如下参数中的至少一者：

图7的操作701、操作702分别对应于图3的操作301和操作302。
如图7所示，该流程还可以包括：
操作703、网络设备101基于收到的接收天线的参数得到译码模型；
操作704、网络设备101配置资源，并将编码模型有关的模型信息发送给终端设备102；以及
操作705、终端设备102根据接收到的模型信息，得到编码模型。
在操作703中，网络设备101可以根据接收天线的参数对译码模型进行训练，从而得到译码模型。此外，网络设备101也可以存储多个已经离线训练完毕的译码模型，并根据接收天线的参数以及接收天线与译码模型的对应关系，选择译码模型。
编码模型和译码模型之间具有对应关系。在操作704中，网络设备101可以配置用于发送模型信息的资源，并且，根据在操作703中确定的译码模型，将译码模型对应的编码模型有关的模型信息发送给终端设备102。
操作705可以和操作303对应。在操作705中，终端设备102根据接收到的模型信息，得到编码模型。例如，该模型信息是编码模型的模型系数，由此，终端设备102直接利用该模型系数，得到编码模型；又例如，该模型信息可以是与模型系数对应，终端设备102可以从终端设备102存储的多组模型系数中提取与该模型信息对应的模型系数，并根据提取的模型系数，得到编码模型。
终端设备102和网络设备101在分别得到编码模型和译码模型的情况下，终端设备102和网络设备101之间可以进行与信道状态信息(例如，信道系数矩阵)反馈相关的处理。
图8是本申请的通信系统基于第一方面的参数发送方法进行CSI反馈的一个流程示意图。
如图8所示，该流程包括：
操作801、网络设备101通过信令为下行信道状态信息的测量配置测量资源，其中，信令例如是RRC，MAC CE或下行控制信息(DCI)，测量资源可以是CSI-RS和/或SSB等参考信号；
操作802、网络设备101配置CSI反馈汇报所需要的参数；
操作803、网络设备101通过下行信道发送用于CSI测量的参考信号；
操作804、终端设备102在接收到用于CSI测量的参考信号以后，进行信道估计，以得到无线信道的信道系数矩阵；
操作805、终端设备102将信道系数矩阵送入编码器，编码器基于编码模型对信道系数矩阵进行压缩；
操作806、终端设备102根据CSI反馈汇报的配置，在相应的时频资源上，发送压缩后的信道系数矩阵；
操作807、网络设备101在收到压缩后的信道系数矩阵后，将其送入译码器，译码器基于译码模型进行解压缩，从而恢复出原始的信道系数矩阵；
操作808、网络设备101根据恢复出的原始的信道系数矩阵来调度下行数据的发送。
图8的流程描述了利用编译码器进行下行信道CSI(例如，信道状态矩阵)反馈的方法，通过编码器的压缩，在信道系数相关性比较好的情况下，例如，对于平坦衰落信道，能够大幅度的降低信道状态信息的反馈量。
在第一方面的实施例中，编码模型可以采用AI模型，译码模型也可以采用AI模型。
图9是采用AI模型的编码模型和采用AI模型的译码模型的一个示意图。
如图9所示，用于CSI压缩的编码模型91被应用于终端设备，用于解压缩的译码模型92被应用于网络设备。假设网络设备的发射天线端口的数目为32，终端设备的接收天线端口的数目为2，通信系统的带宽为24个资源块(RBs)，信道状态信息-参考信号(CSI-RS)在频域上的密度为0.5，即2个RB上有1个CSI-RS信号，那么 频域上总共有12个CSI-RS信号。输入编码模型91的数据维度为12×32×2×2(即，频域上RS数目×网络设备发射天线端口的数目×终端设备接收天线端口的数目×I/Q两路)。
如图9所示，编码模型91包括：输入层(input)911、3×3卷积层(3×3conv)912、1×9卷积层(1×9conv)913、9×1卷积层(9×1conv)914、3×3卷积层(3×3conv)915、连接层(concat)916、1×1卷积层(1×1conv)917、全连接层(FC)918以及量化器919。其中，9×1卷积层(9×1conv)914和3×3卷积层(3×3conv)915的处理结果在连接层916进行合并。
编码模型91输出压缩后的信道状态信息，该压缩后的信道状态信息通过空口发送给网络设备。
如图9所示，译码模型92包括：全连接层(FC)921、5×5卷积层(5×5cov)922、第一信道重建模块(Channel Reconstruction Block，CRBlock)923、第二信道重建模块(Channel Reconstruction Block，CRBlock)924、3×3卷积层(3×3cov)925以及输出层(output)926。
如图9所示，第一信道重建模块923和第二信道重建模块924可以具有相同的结构，例如，第一信道重建模块923可以包括：2个并行支路，其中，一个支路包括3×3卷积层(3×3cov)，1×9卷积层(1×9cov)和9×1卷积层(9×1cov)，另一个支路包括1×5卷积层(1×5cov)和5×1卷积层(5×1cov)；连接层(concat)，用于对两个之路的结果进行合并；1×1卷积层(1×1cov)；以及加法(add)处理层，用于将1×1卷积层(1×1cov)的输出与5×5卷积层(5×5cov)的输出进行相加处理。
如图9所示，输出层926输出的数据为解压缩后的信道状态信息，其数据维度为12×32×2×2，与编码模型91的输入数据的维度一致。
需要说明的是，上述关于编码模型91和译码模型92的说明只是举例，随着发射天线的信息和接收天线的信息的变化，编码模型91和译码模型92中各层的参数可能发生变化，并且，编码模型91和译码模型92的具体结构也可能发生变化。
