多天线技术是提高无线通信系统的关键技术。随着无线通信系统的发展，对频谱效率的要求越来越高，而多天线技术能提高无线通信系统的频谱效率。但随着使用的天线数目的增加，比如32天线，64天线，128天线等，需要的参考信号的开销越来越大。目前一般用信道状态信息参考信号(channel state information reference signal，CSI-RS)或者探测参考信号(Sounding Reference  Signal，SRS)来估计信道状态信息。比如目前新空口(New Radio，NR)支持{1、2、4、8、12、16、24、32}端口CSI-RS，支持的CSI-RS密度值为0.5、1和2，且CSI-RS的配置是用户或者用户组专用的。从网络侧设备来看，其需要的CSI-RS资源元素(Resource Element，RE)个数可能大于等于天线数目。而一个物理资源块(Physical Resource Block，PRB)的RE个数是有限制的，一般来说是不大于168的。所以在天线数目越来越高的趋势下，如何降低参考信号的开销是当前亟待解决的。
为了便于理解，以下介绍本申请所涉及的概念：

在一些实施例中，传输包括发送或接收。比如发送数据或者信号，接收数据或者信号。
在一些示例中，天线是物理天线。在一些示例中，天线是逻辑天线。在一些示例中，端口和天线可以是互换的概念。在一些示例中，天线为发送天线。在一些示例中，天线为接收天线。在一些示例中，天线包括发送天线和接收天线的天线对。在一些示例中，天线可以是均匀线性阵列。在一些示例中，天线是均匀平面阵列(比如包括Ng行Mg列，Ng，Mg为正整数。)。在一些示例中，天线是均匀圆阵列。在一些示例中，天线可以是非均匀线性阵列。在一些示例中，天线是非均匀平面阵列。在一些示例中，天线是非均匀圆阵列。在一些示例中，天线是定向天线，在一些示例中，天线是全向天线。在一些示例中，天线是双极化天线。在一些示例中，天线是单极化天线。在一些实施例中，天线的排列称为天线的拓扑或天线的拓扑排列，可以通过基站配置所述的天线拓扑，基站通过接收所述的天线拓扑获得基站的天线是几行几列的，是线性阵列还是平面阵列或者圆形阵列。天线是均匀排列的还是非均匀排列的。
在一些实施例中，为了计算信道状态信息或者进行信道估计，移动性管理，定位等，需要基站或者用户发送参考信号(RS，Reference Signal)，参考信号包括但不限于信道状态信息参考信号(Channel-State Information reference signal，CSI-RS)，它包括零功率的CSI-RS(Zero Power CSI-RS，ZP CSI-RS)和非零功率的CSI-RS(Non-Zero Power CSI-RS，NZP CSI-RS)，信道状态信息干扰测量信号(Channel-State Information-Interference Measurement，CSI-IM)，探测参考信号(Sounding Reference Signal，SRS)，同步信号块(Synchronization Signals Block，SSB)、物理广播信道(Physical Broadcast Channel，PBCH)、同步广播块/物理广播信道(SSB/PBCH)，NZP CSI-RS可以用来测量信道或者干扰，CSI-RS也可以用来做跟踪，叫做跟踪参考信号(CSI-RS for Tracking，TRS)，而CSI-IM一般用来测量干扰，SRS用来进行信道估计。另外，用于传输参考信号的时频资源包括的资源元素(Resource Element，RE)集合称为参考信号资源，比如，CSI-RS resource，SRS resource，CSI-IM resource，SSB resource。在本文中，SSB包括同步信号块和/或物理广播信道。
在一些实施例中，在通信系统中，传输参考信号的资源可以称为参考信号资源，为了节省信令开销等，可能会把多个参考信号资源分成多个集合(比如 CSI-RS resource set，CSI-IM resource set，SRS resource set)，参考信号资源集合包括至少一个参考信号资源，而多个参考信号资源集合可以都来自同一个参考信号资源设置(比如CSI-RS resource setting，SRS resource setting，CSI-RS resource setting，其中CSI-IM resource setting可能和CSI-IM resource setting合并，都称为CSI-RS resource setting)来配置参数信息。
在一些实施例中，基站配置测量资源信息，测量资源信息用于获取信道状态信息。其中，测量资源信息包括CN个信道测量资源(Channel Measurement Resource，CMR)信息和CM个干扰测量资源(Interference Measurement Resource，IMR)信息，CN和CM为正整数。基站在一个报告配置(report config)或报告设置(reporting setting)中配置测量资源信息。
在一些示例中，为了更好地传输数据或者信号，基站或者终端需要获取信道状态信息，其中，信道状态信息可以包括以下至少之一：信道状态信息-参考信号资源指示(CSI-RS Resource Indicator，CRI)、同步信号块资源指示(Synchronization Signals Block Resource Indicator，SSBRI)、参考信号接收功率(Reference Signal Received Power，RSRP)、差分RSRP(Differential RSRP)、信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、层指示(Layer Indicator，LI)、秩指示(Rank Indicator，RI)、级1的信干噪比(Level 1Signal to Interference plus Noise Ratio，L1-SINR)、差分L1-SINR(Differential L1-SINR)。这里预编码矩阵指示是预编码信息中的一种，即基于码本实现预编码信息的情况，比如包括第一类预编码信息。预编码信息还包括基于非码本实现的方式，比如第二类预编码信息。在一个示例中，只包括第一类预编码信息的CSI称为第一类CSI，在一个示例中，包括第二类预编码信息的CSI称为第二类CSI。
在一些实施例中，终端和基站通过第一类预编码信息来传输与信道匹配的信道状态信息，第一类预编码信息是基于传统的信道特征矩阵或者特征矩阵的量化值构成的预编码信息。比如基于码本的方法，比如LTE的中的N天线的码本，这里N＝2,4,8,12,16,24，32，NR中type I码本，type II码本，type II port selection码本，enhanced type II码本，enhanced type II selection码本，Further enhanced type II selection码本。这里的码本包括L个码字，它的主要思想是基站和终端预先根据规定的公式或者表格或者字典的方式保存L个码字。在一些示例中，码字是一个向量。在一些示例中码字是矩阵，矩阵包括r列，每列也是一个向量。可选地，所述矩阵的每列是相互正交的。在一些示例中，构成码字的向量是一个0-1向量，其中整个向量只有一个值为1，其它的值为零。在一些示例中，构成码字的向量是一个DFT矢量(离散傅里叶变换，Discrete Fourier Transform，DFT)。在一些示例中构成码字的向量是两个或者两个以上的DFT矢量通过张量积 (kronecker积)获得。在一些示例中构成码字的向量是两个或者两个以上的DFT矢量通过乘以不同的相位旋转连接得到。在一些示例中构成码字的向量是两个或者两个以上的DFT矢量通过张量积(kronecker积)以及乘以相位旋转获得。基站或者终端通过查找L个码字，找到跟信道最匹配的码字作为最优码字以传输数据或者信号。这里跟信道匹配的码字包括但不限于以下至少之一：码字和信道的距离最小，码字和信道的相关性最大，码字和信道的最优的右奇异向量或者矩阵的距离最小，码字和信道的最优的右奇异向量或者矩阵相关性最大，码字和信道计算得到的信噪比最大等。L为大于1的整数，一般来说大于发送天线数目。
在一些示例中，终端和基站通过第二类预编码信息传输与信道匹配的信道状态信息，第二类预编码信息是基于AI获得的信道状态信息，在一个示例中，基站和终端通过自编码器的编码器获得信道状态信息，自编码器包括一个编码器和解码器，其中，编码器在终端而解码器在基站侧。终端通过编码器对获得信道H进行压缩得到压缩后的H1，并将压缩后的信道H1量化反馈给基站，基站接收量化后的H1，量化后的H1去量化后输入解码器，解码器对其进行解压缩，从而恢复H。在一个示例中，H包括K0个元素，终端从H中选K个元素作为H1，对H1量化进行反馈，基站接收所述K个量化的元素并将它去量化，将去量化的K个元素输入目标模块，目标模块输出K0个元素作为对H的恢复，从而得到所述H的预编码矩阵。其中，K和K0为大于1的整数，且K<K0。这里，通过压缩器的H1或从H中选择的K个元素都为第二类预编码信息。并且为了简单起见，量化后的H1也称为第二类预编码信息。在一个示例中，第二类预编码信息也可以是通过其它非AI方式生成的与第一类预编码信息不同的预编码矩阵。在一个示例中，第二类预编码信息也可以是所述第一类预编码信息之外的预编码矩阵。
在一些示例中，为了传输CSI，比如终端反馈CSI，基站接收CSI，需要终端和基站定义一个CSI报告(CSI report或者CSI report congfig)，其中CSI报告至少定义了如下参数之一：用于反馈CSI的时频资源，CSI包括的reportQuantity，CSI反馈的时域类别reportConfigType，测量信道资源，测量干扰资源，测量的带宽大小等信息。其中CSI报告可以在上行传输资源上传输，其中上行传输资源为用于传输上行信令或者数据的资源，包括但不限于PUSCH和PUCCH，而CSI report也包括时域特性，包括周期的CSI报告(periodic CSI report，P-CSI)，非周期的CSI报告(aperiodic CSI report，AP-CSI)，半持续的CSI报告(semi-persistent CSI report，SP-CSI)。一般来说，P-CSI传输的比特数目相对较小，在PUCCH上传输，而A-CSI传输的比特数较多，一般在PUSCH上传输，而SP-CSI可以基于PUSCH传输，也可以基于PUCCH传输。其中， 基于PUCCH传输的P-CSI一般用高层信令(无线资源控制，Radio Resource Control，RRC)配置，基于PUCCH传输的SP-CSI也是用高层信令(RRC和/或MAC CE)配置或者激活，而基于PUSCH传输的SP-CSI或者A-CSI都是通过物理层信令(下行控制信息，Downlink control information，DCI)触发，而DCI一般在物理下行控制信道(Physical downlink control channel，PDCCH)上传输。
在一些实施例中，通过一个CSI报告反馈信道状态或者信道信息可以指，将所述信道状态或者信道信息承载在所述CSI报告指示的上行传输资源上，并通过所述上行传输资源传输所述信道状态或者信道信息。在一些实施例中，反馈信道状态或者信道信息可以指，将所述信道状态或者信道信息承载在上行传输资源上，并通过所述上行传输资源传输所述信道状态或者信道信息。
在一些实施例中，基站通过高层信令和/或物理层信令给终端配置了N个需要向基站反馈的CSI报告(CSI report)，每个CSI报告都有一个索引值(identity，ID)，称为CSI reportID，终端可以根据自己的计算能力或者处理能力，以及基站的要求选择N个CSI报告中的M个CSI报告。并根据上行反馈的资源，反馈该M个CSI报告中的至少一个CSI报告，其中N和M为正整数，且M<＝N。在一个示例中，需要反馈M个CSI报告，但所述M个报告中至少有两个报告的反馈资源是冲突的，所述两个报告的反馈资源冲突是指用于反馈所述两个报告对应的传输资源(比如PUCCH或者PUSCH)中至少有一个符号是相同的和/或至少有一个子载波是相同的。
在一些示例中，信道信息为根据参考信号(比如CSI-RS)获得的用于描述通信节点间的信道环境的信息，比如时域信道矩阵，频域信道矩阵。在一些示例中，信道信息是一个复数矩阵，跟发送天线数目Nt，接收天线数目Nr，资源元素(Resource Element，RE)有关。比如在一个物理资源块上至少有一个Nr*Nt的信道矩阵。基站在1个时隙上发送用于信道测量的参考信号。终端在一个时隙上接收所述用于信道测量的参考信号。根据接收的所述参考信号获得对应时隙的信道信息H。
在一些实施例中，一个信道信息是N个端口的信道信息或N个发送端口的信道信息，主要是指信道信息是发送端口数目为N的信道信息，比如在每个RE或者PRB上，N个端口信道信息为一个Nr*N的复数矩阵。
在一些实施例中，一个信道信息是M个接收端口的信道信息，主要是指信道信息是接收端口数目为M的信道信息，比如在每个RE或者PRB上，M个接收端口信道信息为一个M*Nt的复数矩阵。在一些实施例中，神经网络可以将一个Nr1*Nt1矩阵预测为一个Nr*Nt的信道信息，其中，Nr1，Nt1，Nt，Nr为正 整数，且Nt1<Nt和/或Nr1<Nr,这时可以称信道信息为N个发送端口M个接收端口的信道信息。
在一些示例中，可以通过目标模块将一个参考信号获得的信道信息确定为预测信道信息。在一些示例中，参考信号获得的信道信息包括第一信道信息，第二信道信息，第i信道信息等，i＝1，…，K，一般来说，参考信号获得的信道信息对应的端口数目小于预测信道信息。在一些示例中，目标模块是一个功能模块，可以基于人工智能实现，比如基于目标模块实现，比如基于神经网络实现。在一些示例中，目标模块可以基于一些非线性映射关系实现，其中非线性映射关系把输入的信道信息通过一系列的非线性操作映射到输出的预测信道信息中，这里信道信息包括但不限于信道矩阵，时域信道矩阵，频域信道矩阵之一。在一些示例中，目标模块也可以称为操作，处理，映射等。目标模块的作用可以是将一个M端口的信道信息处理为一个N端口的预测信道信息，M小于N。
在一个示例性实施方式中，图1为本申请实施例提供的一种传输方法的流程示意图，本实施例提供的方法应用于第一通信节点。所述方法包括如下步骤：

在一个实施例中，第一通信节点可以传输小于M1个端口的第一信道信息至第二通信节点，第二通信节点获取到小于M1个端口的第一信道信息后可以确定N个端口的预测信道信息。
在一个实施例中，第一通信节点可以自身直接基于K套参考信号确定N个端口的预测信道信息。如确定K套参考信号对应的信道信息，进而基于目标模块确定N个端口的预测信道信息。
本申请实施例提供的传输方法，第一通信节点基于接收的K套参考信号确定N个端口的预测信道信息，实现了以较小的端口(即K套参考信号对应的端口)来预测N个端口的信道，降低了参考信号的开销。

在一个实施例中，终端可能由于能力问题或者发现场景改变，不能输出N个端口的预测信道信息，或者输出的N个端口的预测信道信息，导致估计的预测信道信息H跟实际的信道差异很大。此时，终端可能需要回退到传统的信道估计方法，如非AI的信道预测方法，线性插值的方法估计信道。
A)终端估计M1个端口的第一信道信息H1。反馈第一信道信息H1。并指示基站根据第一信道信息H1恢复预测信道信息H。如通过第二指示信息指示第二通信节点第一通信节点传输的是第一信道信息H1，需要第二通信节点根据所述第一信道信息H1对应的信道状态信息确定N个端口对应的预测信道信息。

在一些实施例中，为了更好地从M个端口的第一信道信息H1预测N个端口的预测信道信息H。基站根据需要配置实际传输的端口数目M和预测的端口数目N的取值，并通过信令指示给终端。终端通过接收基站的指示获得所述的实际传输的端口数目M和预测的端口数目N。
在一些示例中，基站和终端约定实际传输的端口数目M和预测的端口数目N的取值。在一些示例中，基站和终端根据目标模块的输入确定实际传输的端口数目M。

在一些实施例中，为了更好从M个端口的第一信道信息H1获得N个端口的预测信道信息H。由于天线的排列种类很多，线性阵列，平面阵列，双极化，圆形阵列等，天线间距又可以是均匀的和非均匀的。而从N个天线中选择其中 的M个天线进行参考信号传输也有C(M,N)种可能。所以，在一些示例中，基站需要通过信令指示终端M个端口对应的天线排列是几行几列。在一些示例中，基站需要通过信令指示终端N个预测端口对应的天线排列是几行几列。在一些示例中，基站需要通过信令指示终端M个端口对应的天线在N个端口中的索引或者位置。

在一个示例中，周期参考信号以第n个时隙开始传输，每隔T个时隙传输一次，即在n+o*T的时隙传输，o为大于等于0的整数。在一个示例中，每隔周期传输的参考信号有相同的端口数目。在一个示例中，每隔周期传输的参考信号端口数目不同，比如在o为奇数时，传输的是端口数目为M11的参考信号，在o为偶数时，传输的是端口数目为M12的参考信号。M11和M12为不同的正整数。
在一个示例中，每隔周期传输的参考信号端口数目不同，比如在持续X个周期传输M21个端口的参考信号，然后持续Y个周期接收M22个端口的参考信号。M21和M22为不同的正整数。X和Y为正整数。比如连续4个周期传输M21个端口的参考信号，然后1个周期传输M22个端口的参考信号。X和Y需要配 置。
在一个示例中，SP参考信号以第n个时隙开始传输，每隔T个时隙传输一次，即在n+o*T的时隙传输，o为大于等于0且小于等于C的整数。在一个示例中，持续传输参考信号的C个周期内，每个周期传输的参考信号有相同的端口数目。在一个示例中，持续传输参考信号的C个周期内，每个周期传输的参考信号端口数目不同，比如在o为奇数时，传输的是端口数目为M31的参考信号，在o为偶数时，传输的是端口数目为M32的参考信号。在一个示例中，规定最后一个周期，即k＝C时固定传输端口数目为M32的参考信号。在一个示例中，规定最后一个周期，即k＝C时固定传输端口数目为M31的参考信号。M31和M32为不同的正整数。图2h为本申请实施例提供的一种参考信号传输示意图，参见图2h，C等于4，在k等于4时，传输M31的参考信号,M31等于8，M32等于4。
在一个示例中，持续传输参考信号的C个周期内，每个周期传输的参考信号端口数目不同，比如在持续S个周期传输W1个端口的参考信号，然后持续L个周期接收W2个端口的参考信号。W1和M12为不同的正整数。S和L为正整数。比如连续4个周期传输W1个端口的参考信号，然后1个周期传输W2个端口的参考信号。S和L需要配置。在一个示例中，规定最后一个周期，即k＝C时固定传输端口数目为W2的参考信号。在一个示例中，规定最后一个周期，即k＝C时固定传输端口数目为W1的参考信号。
