终端设备110可以是一种具有无线收发功能的设备，可以部署在陆地上(如室内或室外、手持、穿戴或车载等)；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星等)。一些终端设备110的举例为：UE、手机、移动台、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、手持计算机、上网本、个人数字助理(Personal Digital Assistant，PDA)等可以联网的用户设备，或虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等，或物联网中的物联网节点，或车联网中的车载通信装置，或娱乐、游戏设备或系统，或全球定位系统设备等。本申请实施例对终端设备的形态不做限定，另外，终端设备110可以简称终端。

为了便于本领域技术人员的理解，以下先对通信系统中涉及的相关概念进行介绍：
在本申请实施例中，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，需要第二通信节点(如基站)或者第一通信节点(如终端)发送参考信号(Reference Signal，RS)，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)、同步信号块/物理广播信道(SSB/PBCH)。其中，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，因此CSI-RS也可以叫做跟踪参考信号(CSI-RS for Tracking，TRS)；CSI-IM一般用来测量干扰，SRS用来进行信道估计或获取上行预编码。另外，用于传输参考信号的资源元素(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。在本申请实施例中，SSB可以包括同步信号块和/或物理广播信道。
在本申请实施例中，传输参考信号的资源也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组合成一个集合(比如CSI-RS resource set，CSI-IM resource set，SRS resource set)，一个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都可以来自同一个参考信号资源设置(比如CSI-RS resource setting，SRS resource setting，CSI-IM resource setting，其中，CSI-RS resource setting可能和CSI-IM resource setting合并，都称为CSI-RS resource setting)，通过参考信号资源设置来配置参考信号的参数信息。
在本申请实施例中，第二通信节点配置测量资源信息，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。第二通信节点在一个报告配置(report config)或报告设置(reporting setting)中配置测量资源信息。其中CN个CMR信息用于终端进行信道测量，CM个IMR信息用于终端对所受到的干扰进行测量。
在本申请实施例中，两个天线端口被称为准共位置(quasi co-located，QCL)的意思是：如果一个天线端口上的符号所传输的信道的属性可以从另一个天线端口上的符号所传输的信道推断出来，则这两个天线端口被称为准共位置。一般来说，QCL的两个端口来自同一个基站或节点。这里说的信道属性包括但不限于：平均增益(average gain)，延迟扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒平移(Doppler shift)，平均延迟参数(average delay parameters)，空间用户接收参数(spatial UE-Rx parameters)等。所述的天线端口包括但不限于解调参考信号(Demodulation Reference Signal，DMRS)导频端口或者索引，SRS端口或者索引，SS block端口或者索引。QCL关系包括CSI-RS资源配置信息和同步信号块索引(synchronization signal block index)之一。其中，同步信 号块索引包括主同步信号块索引和辅同步信号块索引。信道状态信息参考信号资源配置信息至少包括以下信息之一：CSI-RS的起始符号索引，结束符号索引，图样，密度，导频的循环移位序列，正交码(Orthogonal Cover Code，OCC)等信息。
准共位置(QCL)可以包括QCL type A、QCL type B、QCL type C和QCL Type D。两个端口满足准共位置关系表示一个端口的大尺度信息可以通过另外一个端口的大尺度信息推导出来，大尺度信息包括但不限于：多普勒平移(Doppler shift)、多普勒扩展(Doppler spread)、平均延迟(average delay)、延迟扩展(delay spread)、空间接收参数(Spatial Rx parameter)。其中，一种QCL Type的分类如下：
-'QCL-TypeA':{Doppler shift,Doppler spread,average delay,delay spread}
-'QCL-TypeB':{Doppler shift,Doppler spread}
-'QCL-TypeC':{Doppler shift,average delay}
-'QCL-TypeD':{Spatial Rx parameter}
为了更好地传输数据或者信号，第二通信节点需要获取信道状态信息，如图2所示，提供了一种获取信道状态信息的方式，例如，根据参考时隙n以前的N个时隙(如slot n-8，slot n-6，slot n-4，slot n-2)的信道信息预测参考时隙n及参考时隙n之后的M个时隙(如slot n，slot n+2，slot n+4)的信道状态信息。但是，在一些场景下，第二通信节点由于资源冲突或者其它的原因，只传输了N套参考信号中的K套参考信号，导致终端不能有效获得参考时隙n之前的N个信道信息，仅获得了K个信道信息，此种情况会导致原来的根据N个信道信息确定M个信道状态信息的反馈的失效，为此，本申请实施例提供的技术方案旨在接收的参考信号套数少于期望的参考信号套数的情况下解决信道状态信息获取的技术问题。
图3为本申请实施例提供的信道状态信息处理方法的一种流程示意图。该方法应用于第一通信节点，在本实施例中，第一通信节点可以为终端，第二通信节点可以为基站，如图3所示，该方法可以包括：
S301、接收N套参考信号配置信息和K套参考信号。
第二通信节点传输了N套参考信号配置信息，由于第二通信节点配置参考信号资源之间有冲突或者其它原因，导致第二通信节点仅传输了K套参考信号，其中，K，N为正整数，且K小于N。因此，第一通信节点基于接收到的N套参考配置信息仅可以接收对应的K套参考信号。N套参考信号配置信息对应N套参考信号，所述K套参考信号可以为N套参考信号的一部分。例如，K套参考信号可以是N套参考信号中的前K套参考信号、后K套参考信号、中间连续 的K套参考信号或者任意非连续的K套参考信号。
在一个实施例中，参考信号配置信息包括资源类别(resourceType)，在此资源类别定义了参考信号的时域传输特性，可选地，资源类别可以包括以下之一：周期的(periodic)参考信号，非周期的(aperiodic)参考信号，半持续的(semiPersistent)参考信号。
在一个实施例中，N套参考信号配置信息可以包括K1个周期的参考信号，K2个非周期的参考信号，K3个半持续的参考信号。其中，K1，K2，K3为非负整数，且K1+K2+K3＝N。在一个实施例中，N套参考信号配置信息包括的资源类别可以是相同的，即，所述K1，K2，K3中有两个取值为零，比如N套参考信号配置信息可以包括都是周期的参考信号或都是非周期的参考信号或都是半持续的参考信号。在一个实施例中，N套参考信号配置信息中至少包括两种参考信号的资源类别，比如所述K1，K2，K3中至少两个取值大于零。示例性的，第二通信节点需要配置和传输4套参考信号，其中，这4套参考信号可以是周期的，半持续的，非周期中任意一种。例如，在一种配置下，有两套周期的参考信号，一套非周期的参考信号，一套半持续的参考信号；在另一种配置下，有三套半持续的参考信号，一套非周期的参考信号；在又一种配置下，有两套周期的参考信号，两套非周期的参考信号；在又一种配置下，有两套半持续的参考信号，两套周期的参考信号等等。
在一个实施例中，N套参考信号配置信息有相同的准共位置参数。
在一个实施例中，一套参考信号可以包括以下之一：一个参考信号资源、一组参考信号资源、一个参考信号资源集合以及一个参考信号资源配置对应的参考信号资源。
示例性的，一套参考信号可以是一个参考信号资源，比如一个信道状态信息参考信号(Channel-State Information reference signal，CSI-RS)resource，或一个探测参考信号(Sounding Reference Signal，SRS)resource，或者一个同步信号块(Synchronization Signals Block，SSB)resource。在一个实施例中，一套参考信号可以是一组参考信号资源，比如一组CSI-RS resource，或一组SRS resource，或者一组SSB resource。在一个实施例中，一套参考信号可以是一个参考信号资源集合，比如一个CSI-RS resource set，或一个SRS resource set，或者一个SSB resource set。在一个实施例中，一套参考信号可以是一个参考信号资源配置对应的参考信号资源，比如一个CSI-RS resource config/setting，或一个SRS resource config/setting，或者一个SSB resource config/setting。
示例性的，一套参考信号中的参考信号还可以是除CSI-RS、SSB、SRS外的其它概念的参考信号，可能在不同的系统中有不同的名字，即本申请实施例 中的参考信号也可以是用于获取信道状态信息、信道信息、移动性管理，定位管理的其它参考信号。可选地，参考信号也叫导频等。在一个实施例中，一套参考信号可以包括一套用于信道测量的参考信号和一套用于干扰测量的参考信号。
S302、根据所述K套参考信号获取K个信道信息。
信道信息为根据参考信号(例如，CSI-RS)获得的用于描述第一通信节点和第二通信节点之间信道环境的信息，比如时域信道矩阵、频域信道矩阵。在一个实施例中，信道信息是一个复数矩阵，与发送天线数目Nt、接收天线数目Nr以及资源元素(Resource Element，RE)有关。例如，在一个物理资源块(Physical Resource Block)上至少有一个Nr*Nt的信道矩阵。
第二通信节点在K个时隙发送用于信道测量的参考信号，第一通信节点接收K个时隙发送的用于信道测量的参考信号，并根据接收的K个时隙的参考信号分别获得对应时隙的信道信息，从而得到K个信道信息。在一个实施例中，所述K套参考信号在不多于K个时隙传输。例如，有的时隙在不同的频域资源上传输了多于一套的参考信号。
可选地，K个信道信息可以为参考时隙之前的信道信息。在一个实施例中，参考时隙可以包括以下至少之一：第一通信节点和第二通信节点之间约定的一个时隙、一个当前的时隙、第二通信节点指示的一个时隙、第二通信节点指示的一个时隙加一个固定偏置得到的时隙或者第一通信节点收到第二通信节点指示信令的时隙加一个固定的偏置得到的时隙。
S303、根据所述K个信道信息确定M个信道状态信息。
M为正整数，且M大于或等于1。在一个实施例中，所述M个信道状态信息为参考时隙以及参考时隙之后的信道状态信息。
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 1 Signal to Interference plus Noise Ratio，L1-SINR)、差分L1-SINR(Differential L1-SINR)、预编码信息等。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。预编码信息还包括基于非码本实现的方式，例如，第二类预编码信息。在一个示例中，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。
在一个实施例中，第一通信节点和第二通信节点可以通过第一类预编码信息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。例如，基于码本的方法，如LTE的中的N天线的码本，这里N＝2，4，8，12，16，2432，新空口(New Radio，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，它的主要思想是第一通信节点和第二通信节点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。在一个示例中，码字是一个向量。在一个示例中，码字是矩阵，矩阵包括r列，每列也是一个向量。矩阵的每列是相互正交的。在一个示例中，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。在一个示例中，构成码字的向量是一个DFT矢量(离散傅里叶变换，Discrete Fourier Transform，DFT)。在一个示例中，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。在一个示例中，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。在一个示例中，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。第一通信节点或者第二通信节点通过查找L个码字，找到跟信道最匹配的码字作为最优码字来传输数据或者信号。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。其中，L为大于1的整数，一般来说大于发送天线数目。
在一个实施例中，第一通信节点和第二通信节点也可以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获得信道状态信息。在一个示例中，第一通信节点和第二通信节点通过自编码器的编码器获得的信道状态信息，自编码器包括一个编码器和一个解码器。其中，编码器部署在第一通信节点(如终端)，解码器在部署第二通信节点(如基站)。第一通信节点通过编码器对获得的信道H进行压缩得到压缩后的H1，并将压缩后的信道H1量化反馈给第二通信节点，第二通信节点接收量化后的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，第一通信节点从H中选K个元素作为H1，对H1量化进行反馈，第二通信节点接收所述K个量化的元素并将它去量化，将去量化的K个元素输入AI模块，AI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小于K0。这里，通过压缩器的 H1或从H中选择的K个元素都可以称为第二类预编码信息。并且，为了简单起见，量化后的H1也可以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。
在得到K个信道信息之后，第一通信节点可以基于K个信道信息确定M个信道信息，并对M个信道信息进行量化，得到M个信道状态信息。示例性的，可以是通过AI方式对K个信道信息进行处理，得到M个信道信息，例如，将K个信道信息依次编码后输入第一AI网络，通过第一AI网络确定M个信道信息；也可以通过线性映射的方式，对K个信道信息做滤波或者平均得到M个信道信息；还可以通过非线性映射的方式将K个信道信息处理为M个信道信息。在一个实施例中，还可以对M个信道信息进行编码后输入对应的第二AI网络，通过第二AI网络输出M个信道信息对应的M个信道状态信息。在一个实施例中，还可以直接根据K个信道信息获取M个信道状态信息。
在一个实施例中，根据K个信道信息确定M个信道状态信息，包括：基于K个信道信息中的至少一个信道信息确定一个信道状态信息，其中，所述信道状态信息为第一类预编码信息。
在一个实施例中，可以基于所述K套参考信号中传输时隙最大的参考信号对应的信道信息确定一个信道状态信息。
在一个实施例中，第一通信节点不期望接收小于N套的参考信号。
在一个实施例中，根据K个信道信息确定M个信道状态信息，包括：在K小于或等于第一门限X的情况下，基于K个信道信息中的至少一个信道信息确定一个信道状态信息，其中，该信道状态信息为第一类预编码信息，X为大于1且小于N的整数。
在一个实施例中，根据K个信道信息确定M个信道状态信息，包括：在K小于或等于第二门限Y的情况下，第一通信节点确定0个信道状态信息或确定所述信道状态信息为空集，其中，Y为大于1且小于N的整数。
在一个实施例中，根据K个信道信息确定M个信道状态信息，包括：根据K个信道信息获取N个信道信息；根据第一获取方式和N个信道信息确定M1个信道状态信息，其中，M1为小于或等于M的正整数。这里，可以理解为还有M1个信道状态信息和M-M1个空集，或者此时的M为M1。
在一个实施例中，对K个信道信息补零操作获取N个信道信息。
在一个实施例中，在K大于第一门限X的情况下，根据K个信道信息获取 N个信道信息；根据N个信道信息确定M1个信道状态信息。
在一个实施例中，根据K个信道信息确定M个信道状态信息，包括：根据第二获取方式和K个信道信息确定M2个信道状态信息，其中，所述M2为小于或等于M的正整数。这里，可以理解为还有M2个信道状态信息和M-M2个空集，或者此时的M为M2。
在一个实施例中，在K大于第三门限Z的情况下，根据第二获取方式和K个信道信息确定M2个信道状态信息，其中，Z为大于1且小于N的整数。
在一个实施例中，第一获取方式和第二获取方式中的第一和第二只是用于区分获取信道状态信息的方式，比如第一获取方式为将N个信道信息作为输入的信道状态信息获取方式。第二获取方式为将K个信道信息作为输入的信道状态信息获取方式。比如第一获取方式为第一通信节点或者第二通信节点原来确定的根据信道信息获取信道状态信息的方式，而第二获取方式为第一通信节点或者第二通信节点新确定的根据信道信息获取信道状态信息的方式。
在一个实施例中，第一门限、第二门限、第三门限中的至少之一称为门限、所述门限根据第二通信节点确定，并通过高层信令或者物理层信令指示给第一通信节点，第一通信节点通过接收所述高层信令或者物理层信令确定的所述门限。在一个实施例中，所述门限根据第一通信节点和第二通信节点约定的方式确定。在一个实施例中，所述门限由第二通信节点根据自己的能力确定。
在一个实施例中，还可以向第二通信节点反馈得到的信道状态信息和/或反馈得到的信道状态信息对应的时隙。
时隙可以是时隙(slot)或子时隙(mini slot)。一个时隙或者子时隙包括至少一个符号。这里符号是指一个子帧或帧或时隙中的时间单位，比如可以为一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号、单载波频分复用多址接入(Single-Carrier Frequency Division Multiple Access，SC-FDMA)符号或者正交多址频分复用接入(Orthogonal Frequency Division Multiple Access，OFDMA)符号。
为了传输信道状态信息，需要第一通信节点和第二通信节点定义一个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包括的报告质量(reportQuantity)，CSI反馈的时域类别(reportConfigType)，信道测量资源，干扰测量资源以及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，该上行传输资源可以包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和物理上行控制信道(Physical Uplink Control Channel，PUCCH)；同时，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，可以在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上传输，也可以基于PUCCH上传输。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。即，可选地，可以在上行传输资源中传输上述信道状态信息和信道状态信息对应的时隙。在一个示例中，上述信道状态信息可以承载在至少一个非周期的PUSCH上进行传输。在一个示例中，上述信道状态信息可以承载在至少一个半持续的PUSCH上传输。在一个示例中，上述信道状态信息可以承载在至少一个周期的PUCCH上传输。
在一个实施例中，第二通信节点通过高层信令和/或物理层信令给第一通信节点配置了M个需要反馈的CSI报告，每个CSI报告都有一个索引值(identity，ID)，称为CSI reportID，第一通信节点可以根据自己的计算能力或者处理能力，以及第二通信节点的要求选择M个CSI报告中的MC个CSI报告。并根据上行反馈的资源，反馈该MC个CSI报告中的至少一个CSI报告，其中M和MC为正整数，且MC<＝M。在一个示例中，需要反馈MC个CSI报告，但所述MC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。在一个示例中，第一通信节点需要反馈多个CSI报告，其中，多个CSI报告中至少有L个CSI报告对应的传输资源存在冲突。在一个示例中，存在冲突的L个CSI报告中至少有一个包括第二类预编码信息的报告，其中，L为正整数。基于此，可以根据优先级计算公式计算L个冲突的CSI报告的优先级值(priority value，PV)，并根据优先级值从小到大排序，选择其中优先级小的至少一个CSI报告在上行传输资源中传输。
可选地，在本实施例中，高层信令包括但不限于无线资源控制(Radio Resource Control，RRC)，媒体控制-控制单元(Media Access Control control element，MAC CE)，第一通信节点和第二通信节点之间还可以传输物理层信令，例如，在PDCCH上传输物理层信令或者在PUCCH上传输物理层信令。
在本实施例中，各种参数的指示Indicator，也可以称为索引Index，或者标识(Identifier，ID)，它们是完全等价的概念。例如，无线系统资源标识可以包 括但不限于以下之一：一个参考信号资源、参考信号资源组，参考信号资源配置、信道状态信息报告、CSI报告集合、终端、基站、面板、神经网络、子神经网络、神经网络层等对应的索引。第二通信节点可以通过各种高层信令或者物理层信令指示一个或一组资源的标识给第一通信节点。
图4为本申请实施例提供的信道状态信息处理方法的另一种流程示意图。该方法可以应用于第二通信节点，如图4所示，该方法可以包括：
S401、发送N套参考信号配置信息。
S402、发送K套参考信号。
所述K套参考信号用于第一通信节点获取K个信道信息，并根据所述K个信道信息确定M个信道状态信息，K，N，M为正整数，且K小于N，M大于或等于1。
在一个实施例中，一套参考信号包括以下之一：一个参考信号资源、一组参考信号资源、一个参考信号资源集合以及一个参考信号资源配置对应的参考信号资源。
在一个实施例中，所述N套参考信号配置信息有相同的准共位置参数。
在一个实施例中，所述K个信道信息为参考时隙之前的信道信息，和/或所述M个信道状态信息为参考时隙以及参考时隙之后的信道状态信息。
在一个实施例中，根据所述N套参考信号配置信息，发送所述K套参考信号。
在一个实施例中，所述N套参考信号配置信息对应N套参考信号，所述K套参考信号为所述N套参考信号的一部分。
在一个实施例中，还可以接收第一通信节点反馈的所述信道状态信息和/或接收所述信道状态信息对应的时隙。
下面，罗列一些示例性实施方式，用于解释说明本申请上述实施例公开的信道状态信息处理方法，下述示例性实施方式可以单一执行，也可以组合执行。
在一个示例性实施方式中，第二通信节点由于资源冲突或者其它的原因，只传输了N套参考信号中的K套参考信号，其中，K小于N。第一通信节点接收N套参考信号配置信息对应的K套参考信号，发现接收的参考信号的套数比期望的套数少，在此情况下，第一通信节点可以基于自身的处理能力，确定自身是否具有根据K个信道信息获取M个信道状态信息的能力。如果不具有该能 力，则可以基于K个信道信息中的至少一个信道信息确定一个信道状态信息。
所述信道状态信息为第一类预编码信息，第一类预编码信息可以是通过码本方式对信道信息进行量化后得到的信息。
在基于K套参考信号得到K个信道信息之后，第一通信节点可以选取K个信道信息中的至少一个信道信息，采用预定的方式获取所述至少一个信道信息对应的一个信道状态信息。其中，该预定的方式可以是基于码本的方式。
在一个实施例中，上述预定的方式可以为第一通信节点和第二通信节点之间约定的方式，也可以是第一通信节点根据接收的信令信息确定的方式，还可以是第一通信节点自身确定的方式，并通过反馈对应的信令信息告诉第二通信节点其自身确定的方式。
在一个实施例中，在K小于或等于第一门限X的情况下，第一通信节点基于K个信道信息中的至少一个信道信息确定一个信道状态信息，其中，该信道状态信息为第一类预编码信息，上述X为大于1且小于N的整数。
示例性的，假设第一通信节点接收到的K套参考信号对应的时隙为slot n-8，slot n-6，slot n-4，则第一通信节点可以基于slot n-6，slot n-4中的参考信号确定对应时隙的信道信息，并将得到的两个信道信息处理为一个信道信息，然后通过预设的码本对得到的一个信道信息进行量化，从而得到一个信道状态信息，并反馈该信道状态信息。
在一个实施例中，第一通信节点可以基于K套参考信号中传输时隙最大的参考信号对应的信道信息确定一个信道状态信息。示例性的，假设第一通信节点接收到的K套参考信号对应的时隙为slot n-8，slot n-6，slot n-4，则第一通信节点可以基于slot n-4中的参考信号确定该时隙的信道信息，并通过预设的码本对slot n-4的信道信息进行量化，从而得到一个信道状态信息，并反馈该信道状态信息。在第二通信节点配置了用于传输M个信道状态信息的传输资源的情况下，在本实施例中，第一通信节点基于K个信道信息中的至少一个信道信息确定一个信道状态信息，因此，第一通信节点可以选择M个传输资源中的一个传输资源反馈得到的一个信道状态信息，剩下的M-1个传输资源不做信道状态信息的反馈，即剩下的M-1个传输资源可以用于传输数据或者其它的信令或者信号。
在本实施例中，在第一通信节点不具备基于K个信道信息获取M个信道状态信息的能力时，第一通信节点可以直接回退到传统码本的方式，从K个信道信息中选取至少一个信道信息来确定一个信道状态信息，使得第一通信节点能够在接收的参考信号套数少于期望的参考信号套数的情况下有效获取信道状态 信息。并且，基于K套参考信号中传输时隙最大的参考信号对应的信道信息确定一个信道状态信息，其更能反应参考时隙及参考时隙之后的信道状态，提高了信道状态信息的准确性。
在另一个示例性实施方式中，第二通信节点由于资源冲突或者其它的原因，只传输了N套参考信号中的K套参考信号，其中，K小于N。第一通信节点接收N套参考信号配置信息对应的K套参考信号，发现接收的参考信号的套数比期望的套数少，在此情况下，第一通信节点可以基于自身的处理能力，确定自身是否具有根据K个信道信息获取M个信道状态信息的能力。如果具有该能力，在其中一个实施方式中，第一通信节点可以对K个信道信息补零操作获取N个信道信息，并根据第一获取方式和获得的N个信道信息确定M1个信道状态信息，其中，所述M1小于或等于M。
第一通信节点可以根据K个信道信息对应的参考信号的时隙，确定自身接收了N个信道信息中的哪K个信道信息，并对没有接收到的参考信号对应的信道信息补零矩阵，从而将K个信道信息处理为N个信道信息，基于第一获取方式对N个信道信息进行处理，从而确定M1个信道状态信息。其中，所述零矩阵为Nr*Nt维度的矩阵，或者为Nr*Nt*2维度的矩阵，其中，Nr，Nt为第一通信节点和第二通信节点的天线数目，2为通道数目。示例性的，第一获取方式可以是原有的AI网络，原有的AI网络需要输入N个信道信息，才可以输出M个信道状态信息。因此，如果继续使用原有的AI网络，需要将K个信道信息处理成N个信道信息，才可以继续使用原有的AI网络，在本实施例中，可以对K个信道信息进行补零操作，从而得到N个信道信息。
在本实施例中基于N个信道信息确定M个信道状态信息还是小于M个信道状态信息，也是与第一通信节点的能力有关。
在另一种实施方式中，第一通信节点可以直接根据第二获取方式和K个信道信息确定M2个信道状态信息，其中，所述M2小于或等于M。
第二获取方式可以是新AI网络，即第一通信节点可以搜索一个新AI网络，通过该新AI网络直接将K个信道信息处理为M2个信道状态信息。
在本申请中，AI网络只是实现将N个信道信息确定M1个信道状态信息的一种方式，可以将AI网络替换成处理模块或者其它实现方式。
也就是说，第一通信节点可以将K个信道信息处理成期望的N个信道信息，再基于第一获取方式和N个信道信息确定M1个信道状态信息，也可以直接基于第二获取方式对K个信道信息进行处理，从而得到M2个信道状态信息。选 择哪种处理方式，可以基于第一通信节点所支持的能力，例如第一通信节点仅支持第一获取方式，则可以按照第一获取方式进行处理，如果第一通信节点对两种方式都支持，则可以任意选择一种方式进行处理即可。
可选地，在根据K个信道信息确定M个信道状态信息之前，第一通信节点还可以确定K是否大于第一门限X，在K大于第一门限X的情况下，可以根据对K个信道信息补零操作获取N个信道信息，并根据获得的N个信道信息确定M1个信道状态信息，也可以根据第二获取方式和K个信道信息确定M2个信道状态信息。在K小于或等于第一门限X的情况下，可以基于K个信道信息中的至少一个信道信息确定一个信道状态信息，即在接收到的参考信号的套数远远小于期望的套数时，第一通信节点回退到传统码本的方式，从K个信道信息中选取至少一个信道信息来确定一个信道状态信息，使得第一通信节点能够在接收的参考信号套数少于期望的参考信号套数的情况下获取更为准确的信道状态信息。
在一个实施例中，在K大于第三门限Z的情况下，第一通信节点才根据第二获取方式和K个信道信息确定M2个信道状态信息，即在获取的历史信道信息数量较多的情况下，才使用第二获取方式进行信道状态信息的预测，提高了信道状态信息的准确性。
在一个实施例中，在K小于或等于第二门限Y的情况下，确定0个信道状态信息或确定所述信道状态信息为空集，其中，所述Y为大于1且小于N的整数。也就是说，在接收到的参考信号的套数远远小于期望的套数时，第一通信节点不进行通过K个信道信息确定M个信道状态信息的操作。
在一个实施例中，所述第一通信节点不期望接收小于N套的参考信号。
在本实施例中，第一通信节点可以对K个信道信息补零操作获取N个信道信息，并根据第一获取方式和N个信道信息确定M1个信道状态信息，也可以确定第二获取方式，并基于第二获取方式和K个信道信息确定M2个信道状态信息，使得第一通信节点在原来的根据N个信道信息确定M个信道状态信息的反馈失效的情况下，有效获取信道状态信息。并且，通过设定相应的门限，选择不同的信道状态信息处理方式，使得确定的信道状态信息更加准确。
