具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
首先，对本申请实施例中涉及的名词进行简单介绍：
信道状态信息(Channel State Information，CSI)：
CSI是用于描述通信链路的信道属性的信息。CSI的指示在通信系统中非常重要，其决定了多入多出(Multiple-Input Multiple-Output，MIMO)传输的性能。一般来说，通信系统中的CSI指示可以包括对信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding matrix indicator，PMI)、秩指示(Rank indicator，RI)等信息的指示。
结合参考图1，对CSI的生成与指示方式进行示例性的说明。如图1所示，从流程上看，网络设备会先配置用于CSI指示的指示参数信息，例如终端需要指示CQI、PMI、RI等信息中的哪些信息。同时，终端会配置一些供CSI测量用的参考信号，例如同步信号块(Synchronization Signal Block，SSB)和/或信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。终端通过对上述参考信号的测量，确定当前信道状态信息情况，并确定指示参数信息向基站指示当前信道状态信息，供网络设备基于当前信道情况配置出合理高效的数据传输方式。
人工智能(Artificial Intelligence，AI)：
近年来，以神经网络为代表的人工智能研究在很多领域都取得了非常大的成果，其也将在未来很长的一段时间内，对人们的生产生活起到重要的影响。
请参考图2，其示出了本申请一个实施例提供的神经网络的示意图。如图2所示，一个简单的神经网络的基本结构包括：输入层、隐藏层和输出层。其中，输入层负责接收数据，隐藏层负责处理数据，而最后的结果在输出层产生。如图3所示，各个节点代表一个处理单元，也可以认为是模拟了一个神经元，多个神经元组成一层神经网络，多层的信息传递与处理构造出了一个整体的神经网络。
随着神经网络研究的不断发展，近年来，神经网络深度学习算法被提出，较多的隐藏层被引入，通过多隐藏层的神经网络逐层训练进行特征学习，极大地提升了神经网络的学习和处理能力，并在模式识别、信号处理、优化组合、异常探测等方面被广泛应用。
同时，随着深度学习的发展，卷积神经网络也被进一步地研究。请参考图3，其示出了本申请一个实施例提供的卷积神经网络的示意图。如图3所示，在一个卷积神经网络中，其基本结构包括：输入层、多个卷积层、多个池化层、全连接层及输出层。卷积层和池化层的引入，有效地控制了网络参数的剧增，限制了参数的个数并挖掘了局部结构的特点，提高了算法的鲁棒性。
利用神经网络做信道状态信息指示：
当前的运动通信系统的基础原理大多还是基于对实际通信环境的理论建模与参数选取来完成的，随着对运动通信系统灵活性、适应性、速率以及容量等要求的进一步增强，这种传统的基于经典模型理论的运动通信系统工作方式所能带来的增益逐渐在弱化。当前，已有一些新的研究针对上述问题逐步开展，其中利用人工智能的方式做CSI的获取与指示就是其中之一。
请参考图4，其示出了一个基本的利用神经网络模型做信道状态信息指示的网络架构，在这类方法中，首先编码端(第一节点)将待反馈的信道信息通过编码模型401生成第一信道信息，用于信道状态信息指示；解码端(第二节点)将第一信道信息通过解码模型402生成反馈信道信息，用于信道质量信息恢复。
图5示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR-U系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本申请实施例中，上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile  Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。网络设备120与终端设备14之间通过某种空口技术互相通信，例如Uu接口。

图6示出了本申请一个示例性实施例提供的信息传输方法的流程图，该方法中包括信息发送和信息接收。本申请实施例以上述方法应用于移动通信系统中来举例说明，上述移动通信系统包括第一节点和第二节点。该方法包括：
步骤603：向移动通信系统中的第二节点发送补充反馈信息；补充反馈信息用于对完整信道信息进行增量更新，或，补充反馈信息用于对完整信道信息进行预测。
完整信道信息用于描述信道的全量的信道质量情况。示例性的，完整信道信息是信道在某一时刻的信道信息。例如，在某一特定时域或某一特定空间域上的信道的质量情况。完整信道信息用于描述信道的信道质量情况，完整信道信息用于描述信道在时域、频域、天线维度、入射角度上的质量情况。例如，完整信道信息可以是CSI。
补充反馈信息是根据完整信道信息的增量(变化量)得到的信息。或，补充反馈信息是根据完整信道信息的变化趋势对未来的完整信道信息进行预测的信息。
示例性的，完整信道信息会随着时间变化。相关技术中的方法，第一节点需要向第二节点实时同步当前时刻的完整信道信息，这种信道信息反馈方式的反馈开销过大。因此，本申请提供了补充反馈信息，补充反馈信息可以是两种类型的信息。
第一种：补充反馈信息用于表示完整信道信息的增量。例如，在t时刻的完整信道信息为第一信道信息，在t+1时刻(当前时刻)的完整信道信息为第二信道信息，其中，第二信道信息与第一信道信息之间只有几个数值发生改变，则补充反馈信息可以用于表示第二信道信息与第一信道信息的差值。第二节点在接收到补充反馈信息后，可以根据t时刻的完整信道信息：第一信道信息，以及补充反馈信息，得到t+1时刻的完整信道信息：第二信道信息。从而在减少信道信息反馈的反馈开销的同时，保证第二节点可以获得完整信道信息。
第二种：补充反馈信息用于表示对完整信道信息的预测。示例性的，第一节点可以预测完整信道信息的变化趋势(增量)，或，预测未来的完整信道信息。例如，第一节点根据历史一段时间内完整信道信息的变化趋势，来预测未来时刻与当前时刻完整信道信息的变化量，第一节点通过向第二节点发送补充反馈信息，使第二节点可以根据当前时刻的完整信道信息以及补充反馈信息，得到未来时刻的完整信道信息。再如，第一节点根据历史一段时间内的完整信道信息，来预测未来时刻的完整信道信息，即得到补充反馈信息，通过向第二节点发 送补充反馈信息，来使第二节点得到未来时刻的完整信道信息。
示例性的，完整信道信息可以独立使用的数据，完整信道信息可以独立指示信道的信道质量情况。补充反馈信息需要结合一个时刻的完整信道信息得到另一个时刻的完整信道信息后，使用新得到的完整信道信息来指示信道的信道质量情况。补充反馈信息无法单独用于描述信道的信道质量情况。
在移动通信系统中，存在若干个网络设备和若干个终端，上述网络设备和终端设备均可作为第一节点或第二节点。示意性的，第一节点是网络设备、终端中的一种；第二节点是网络设备、终端中的一种。比如，第一节点是网络设备，第二节点是终端；又如，第一节点是终端，第二节点是网络设备；又如，第一节点是第一终端，第二节点是第二终端；又如，第一节点是第一网络设备，第二节点是第二网络设备。
根据节点类型的不同，第一节点向第二节点发送补充反馈信息的传输方式也不同，具体可分为如下几种可选的传输方式：
在一个实施例中，第一节点是终端设备，第二节点是网络设备，补充反馈信息携带在如下信令中的至少一种信令中：上行控制信息(Uplink Control Information，UCI)、物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)、上行物理共享信道(Physical Uplink Shared Channel，PUSCH)、RRC消息、数据信息。

在一个实施例中，第一节点为网络设备，第二节点为终端设备，补充反馈信息携带在如下信令中的至少一种信令中：下行控制信息(Downlink Control Information，DCI)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Share Channel，PDSCH)、媒体接入控制控制信元Media Access Control Control Element，MAC CE)、无线资源控制(Radio Resource Control，RRC)消息、广播消息、物理广播信道(Physical Broadcast Channel，PBCH)、系统信息块(System Information Block，SIB)、MIB(Master Information Block，主信息块)、数据信息。
在一个实施例中，第一节点和第二节点均为网络设备，第一节点在网络设备之间的链路上传输补充反馈信息。第一节点通过Xn接口向移动通信系统中的第二节点发送补充反馈信息。
步骤606：第二节点接收移动通信系统中的第一节点发送的补充反馈信息。
示意性的，第一节点是网络设备、终端中的一种；第二节点是网络设备、终端中的一种。
对应的，根据节点类型的不同，第一节点向第二节点发送补充反馈信息的传输方式也不同，具体可分为如下几种可选的传输方式：

在一个实施例中，第一节点和第二节点均为网络设备，第二节点接收第一节点通过Xn接口发送的补充反馈信息。
综上所述，本申请实施例提供的信息发送、信息接收方法，移动通信系统中的第一节点通过发送补充反馈信息，使得第二节点可以根据补充反馈信息进行完整信道信息的更新或预 测，进而得到新的完整信道信息，在保证移动通信系统的CSI反馈效果的同时，降低反馈开销。
