Description

信道状态信息反馈方法、接收方法、装置及通信节点
本申请要求在2022年08月10日提交中国专利局、申请号为202210959508.9的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，例如涉及一种信道状态信息反馈方法、接收方法、装置及通信节点。
背景技术
人工智能(Artificial Intelligence，简称AI)/机器学习(Machine Learning，简称ML)已经广泛应用于各行各业，将它引入无线通信系统来获得信道状态信息得到了广泛的研究；其中一个主要应用场景是信道状态信息(Channel State Information，简称CSI)的反馈。一般来说，基于自编码器的方式来实现CSI反馈。自编码器包括一个编码器和解码器，其中，编码器设置在终端侧，而解码器设置在基站侧。
在CSI反馈中，基站会给终端分配反馈CSI的上行传输资源，但由于基站在分配资源时并不知道终端需要传输多少个数据流，以及每个数据流具体传输的比特数目，以及有可能多个CSI在相同的上行传输资源上传输等原因，有可能会导致基站分配的上行传输资源不能有效传输CSI的情况。此时，一种解决方式是通过终端丢弃部分CSI比特来达到传输的目的。但对于基于AI的CSI反馈来说，丢弃部分比特，可能导致基站不能很好地恢复压缩后的信道信息。另外一种解决方法是通过多个信道状态信息报告反馈所述CSI，但多个CSI报告如何反馈所述CSI是需要解决的问题。

在本申请实施例中，人工智能(Artificial Intelligence，简称AI)包括机器学习(Machine Learning，简称ML)，深度学习，强化学习，迁移学习，深度强化学习和元学习等具有自我学习的设备、组件、软件、模块。在一个实施例中，人工智能通过人工智能网络(或称为神经网络)实现，神经网络包括多个层，每层包括至少一个节点。在一个示例中，神经网络包括输入层，输出层，至少一层隐藏层，其中每层神经网络包括但不限于使用了全连接层，稠密层，卷积层，转置卷积层，直连层，激活函数，归一化层，池化层等至少之一。在一个实施例中，神经网络的每一层可以包括一个子神经网络，比如残差块(Residual Network block，或者Resnet block)，稠密网络(Densenet Block)，循环网络(Recurrent Neural Network，简称RNN)等。人工智能网络可以包括神经网络模型和/或神经网络模型对应的神经网络参数，其中，神经网络模型可以简称为网络模型，神经网络参数可以简称网络参数。一个网络模型定义了神经网络的层数，每层的大小，激活函数，链接情况，卷积核和大小卷积步长，卷积类型(比如1D卷积，2D卷积，3D卷积，空心卷积，转置卷积，可分卷积，分组卷积，扩展卷积等)等网络的架构，而网络参数是网络模型中每层网络的权值和/或偏置以及它们的取值。一个网络模型可以对应多套不同的神经网络参数取值以适应不同的场景。一个神经网络模型可以对应多个不同的神经网络参数取值。通过线上训练或者线下训练的方式获得神经网络的参数。比如通过输入至少一个样本和标签，训练神经网络模型以获得神经网络参数。

在本申请实施例中，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，需要基站或者用户发送参考信号(Reference Signal，简称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，简称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，简称NZP CSI-RS)，信道状态信息干扰测量信号(Channel-State Information-Interference Measurement，简称CSI-IM)，探测参考信号(Sounding reference signal，简称SRS)，同步信号块(Synchronization Signals Block，简称SSB)、物理广播信道(Physical Broadcast Channel，简称PBCH)、同步信号块/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，简称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。
在本申请实施例中，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-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)来配置参考信号参数信息。

在一个示例中，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，简称CRI)、同步信号块资源指示(Synchronization Signals Block Resource Indicator，简称SSBRI)、参考信号接收功率(Reference Signal Received Power，简称RSRP)、差分RSRP(Differential RSRP)、信道质量指示(Channel Quality Indicator，简称CQI)、预编码矩阵指示(Precoding Matrix Indicator，简称PMI)、层指示(Layer Indicator，简称LI)、秩指示(Rank Indicator，简称RI)、级l的信干噪比(Level 1 Signal to Interference plus Noise Ratio，简称L1-SINR)、差分L1-SINR(Differential L1-SINR)，预编码信息。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。比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。
在本申请实施例中，终端和基站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。比如基于码本的方法。比如LTE的中的N天线的码本，这里N＝2，4，8，12，16，2432，新无线电(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。示例性地，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离散傅里叶变换(Discrete Fourier Transform，DFT)矢量。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。基站或者终端通过查找L个码字，找到与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；L为大于1的整数，一般来说大于发送天线数目。
在一个示例中，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，去量化后输入解码器，通过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＜K0。这里，通过压缩器的H1或从H中选择的K个元素都为第二类信道状态信息。并且为了简单起见，量化后的H1也称为第二类信道状态信息。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第一类预编码信息之外的预编码矩阵。
在一个示例中，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report Quantity，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，上行传输资源包括物理上行共享信道(Physical Uplink Shared Channel，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。在本申请实施例中，反馈CSI也 可以称为传输CSI或者发送CSI，比如把信道状态信息承载在上行传输资源上进行反馈或者传输。所述上行传输资源和对应的CSI都是通过一个信道状态信息报告指示。在本申请实施例中，反馈一个CSI报告是指反馈所述CSI报告对应的信道状态信息。
在本申请实施例中，基站通过高层信令和/或物理层信令给终端配置了N个CSI报告(CSI report)，每个CSI报告都有一个索引值(identity，ID)，称为CSI report ID，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报告对应的信道状态信息，其中N和M为正整数，且M≤N。在一个示例中，终端需要反馈M个CSI报告，但M个报告中至少有两个报告对应的传输资源是冲突的，两个报告对应的传输资源冲突是指用于反馈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，终端通过编码器对获得的信道H进行压缩，并将压缩后的信道H1反馈给基站，基站接收H1，并通过解码器的解压缩模块对H1进行解压缩，从而恢复H。示例性地，终端将获得的信道信息H通过编码器压缩，得到第一信道状态信息(这里，它是一个第二类预编码信息)，其中第一信道状态信息包括L个元素，对该L个元素进行量化后得到量化的第一信道状态信息，并反馈量化的第一信道状态信息给基站；基站接收量化的第一信道状态信息，并对它去量化，将去量化的第一信道状态信息输入解码器，并通过解码器的处理得到第二信道状态信息，第二信道状态信息可以理解为信道信息H的估计值或者和它匹配的预编码矩阵。
在一些示例中，终端需要在一个相同的上行传输资源中反馈多个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报告中至少有一个是包括第二类预编码信息的报告，其中L为正整数。根据优先级值计算公式计算L个冲突的CSI报告的优先级值(priority value，简称PV)，并根据优先级值从小到大排序，优先忽略优先级值大的CSI报告，然后忽略优先级第二大的CSI报告，直到满足传输要求为止，在上行传输资源中传输满足要求的优先级最小的L1个CSI报告，其中L、L1为正整数，且L≥L1。在一个示例中，上行传输资源为PUSCH。在一个示例中，上行传输资源为PUCCH。
图1为本申请实施例提供的信道状态信息反馈方法的第一流程示意图，该方法可以由信道状态信息反馈装置或者终端来执行，该装置或者终端可以由软件和/或硬件的方式实现，该装置或终端可以集成在任何具有网络通信功能的智能设备中。如图1所示，信道状态信息反馈方法可以包括以下步骤：
S101、将第一信道状态信息分成至少两个子信道状态信息。
在一个示例中，当终端需要将L个存在冲突的CSI报告在第一上行传输资源上反馈给基站时，终端根据优先级从L个报告中选择L1个报告作为优先传输的CSI报告；其中，L和 L1为正整数且L大于或等于L1；第L1个CSI报告为L1个优先传输的CSI报告中优先级最小的CSI报告；一种情况下，用于传输所述L1个CSI报告的第一上行传输资源只能传输L1-1个CSI报告的内容和部分第L1个报告的内容。将所述第L1个CSI报告对应的信道状态信息拆分成C个子信道状态信息(或者称为信道状态信息子集合，或CSI子集合)，比如C个子第二类预编码信息；在第一上行传输资源上传输C个子信道状态信息中的至少一个子信道状态信息，在第二上行传输资源上传输C个子信道状态信息的至少一个。
在一个示例中，第一上行传输资源传输的子信道状态信息和第二上行传输资源传输的子信道状态信息的交集为零，或者互不相同。
在一个示例中，第一上行传输资源传输的子信道状态信息和第二上行传输资源传输的子信道状态信息的并集为所有的子信道状态信息。
在一个示例中，将第L1个CSI报告对应的信道状态信息(即第一信道状态信息)拆分成2个子信道状态信息，在第一上行传输资源传输第一个子信道状态信息，在第二上行传输资源传输第二个子信道状态信息。一个示例中，将第L1个CSI报告对应的信道状态信息拆分成C个子信道状态信息，在第i个上行传输资源传输第i个子信道状态信息，i＝1，…，C。
在一个实施例中，将至少一个CSI报告对应的信道状态信息拆分成C个子信道状态信息；在至少两个上行传输资源中传输所述C个子信道状态信息中的全部子信道状态信息或者部分子信道状态信息，比如在第一上行传输资源上传输C个子信道状态信息中的至少一个子信道状态信息，在第二上行传输资源上传输C个子信道状态信息中剩下的子信道状态信息。所述多个上行传输资源之间满足预设的时序关系，根据预设的时序关系确定上行传输资源上的传输内容。
S102、通过至少两个上行传输资源反馈至少两个子信道状态信息。
在一个实施例中，终端可以通过至少两个上行传输资源反馈至少两个子信道状态信息。例如，假设终端将第一信道状态信息分成第一子信道状态信息和第二子信道状态信息，则终端可以在第一上行传输资源反馈第一子信道状态信息；在第二上行传输资源上反馈第二子信道状态信息。
在一个实施例中，第L1个CSI报告对应的CSI为第一信道状态信息，包括K比特。但第一上行传输资源传输L1-1个CSI报告的内容和部分第L1个报告的内容(只剩下K1比特用于传输部分第L1个报告的内容)。那么终端可以将第一信道状态信息分成第一子信道状态信息和第二子信道状态信息，其中，K1比特的第一子信道状态信息可以承载在第一上行传输资源上反馈，剩下的K2＝K-K1比特的第二子信道状态信息可以承载在第二上行传输资源上反馈。在一个实施例中，终端还可以将第L1个CSI报告对应的信道状态信息拆分成C个CSI；在第一上行传输资源上反馈第一个子信道状态信息；在第二上行传输资源上反馈第二子信道状态信息；…；在第C个上行传输资源上反馈第C个子信道状态信息。
在一个实施例中，C个子信道状态信息对应的C个上行传输资源分别对应不同的时域资源，如在多个不同的时隙或子时隙。在一个实施例中，C个子信道状态信息对应的C个上行传输资源分别对应不同的频域资源，比如在不同的子载波集合，或者不同的物理资源块(Physical Resource Block，简称PRB)。
在一个实施例中，第一上行传输资源和第一子信道状态信息对应第一信道状态信息报告；第二上行传输资源和第二子信道状态信息对应第二信道状态信息报告。第一上行传输资源和第一子信道状态信息对应第一信道状态信息报告的意思是，第一上行传输资源为第一信道状态信息报告指示的上行传输资源，第一子信道状态信息为第一信道状态信息报告指示的信道状态信息，并且在第一信道状态信息报告指示的第一上行传输资源中传输。第二上行传输资源和第二子信道状态信息对应第二信道状态信息报告的意思是，第二上行传输资源为第二信道状态信息报告指示的上行传输资源，第二子信道状态信息为第二信道状态信息报告指示的信道状态信息，并且在第二信道状态信息报告指示的第二上行传输资源中传输。
在一个实施例中，终端可以在第一上行传输资源上反馈第一子信道状态信息；在第二上行传输资源上反馈第二子信道状态信息。示例性地，终端可以在第一时隙上反馈第一子信道状态信息；在第二时隙上反馈第二子信道状态信息；其中，第二时隙大于第一时隙。这里的时隙也可以是子时隙。
在一个实施例中，第二时隙根据第一时隙和时隙偏置t确定，比如第二时隙等于第一时隙加上时隙偏置。在一个实施中，时隙偏置t根据第二时隙和第一时隙确定，比如时隙偏置等于第二时隙减去第一个时隙；其中，时隙偏置t为正整数。在一个实施例中，第一时隙根据第二时隙和时隙偏置t确定，比如第一时隙等于第二时隙减去时隙偏置；其中，时隙偏置t为正整数。
在一个实施例中，时隙偏置t为大于等于第一门限m1，小于等于第二门限m2的整数，m1和m2为正整数，且m1小于m2。例如，终端可以在第n个时隙上反馈第一子信道状态信息；在第n+t个时隙上反馈第二子信道状态信息；其中，n为整数；t为大于等于m1且小于等于m2的正整数；m1和m2为正整数。
本申请实施例提出的信道状态信息反馈方法，终端先将第一信道状态信息分成至少两个子信道状态信息；然后通过至少两个上行传输资源传输该至少两个子信道状态信息。这样基站可以通过至少两个上行传输资源接收终端反馈的至少两个子信道状态信息，因此不会对信道解码产生影响。而在相关技术中，终端通过丢弃部分CSI比特来达到传输的目的，但对于基于AI的CSI来说，每个CSI编码比特可能都跟信道信息有关，其重要性都是平等的，如果丢弃掉部分比特，可能导致基站不能恢复压缩后的信道，从而导致解码器不能很好地解码。因此，和相关技术相比，本申请实施例提出的信道状态信息反馈方法，可以有效地解决一个上行传输资源不能有效传输至少一个信道状态信息的问题；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。
图2为本申请实施例提供的信道状态信息反馈方法的第二流程示意图。基于上述技术方案进行优化与扩展，并可以与上述可选实施方式进行结合。如图2所示，信道状态信息反馈方法可以包括以下步骤：
S201、将第一信道状态信息分成至少两个子信道状态信息。
S202、在第一上行传输资源反馈第一子信道状态信息；在第二上行传输资源上反馈第二子信道状态信息；其中，该至少两个子信道状态信息包括：第一子信道状态信息和第二子信道状态信息。
在一个实施例中，终端可以将第一信道状态信息分成两个或者多个子信道状态信息；当终端将第一信道状态信息分成两个子信道状态信息时，终端可以在第一上行传输资源上反馈第一子信道状态信息；在第二上行传输资源上反馈第二子信道状态信息。
在一个实施例中，当C＝2时，即将一个CSI报告对应的第一信道状态信息拆分成第一子信道状态信息和第二子信道状态信息；第一信道状态信息可以包括K比特；第一子信道状态信息可以包括K1比特；第二子信道状态信息可以包括K2比特；其中，K1+K2≥K。这里之所以K1+K2大于等于K，是因为，可能会在第一CSI报告和/或第二CSI报告中附带了一些用于指示它们属于同一个信道状态信息中的比特，或者存在一些用于指示第一CSI报告和第二CSI报告的关联性的比特。
本申请实施例提出的信道状态信息反馈方法，终端先将第一信道状态信息分成至少两个子信道状态信息；然后通过至少两个上行传输资源传输该至少两个子信道状态信息。这样基站可以通过至少两个上行传输资源接收终端反馈的至少两个子信道状态信息，因此不会对信道解码产生影响。而在相关技术中，终端通过丢弃部分CSI比特来达到传输的目的，但对于基于AI的CSI来说，每个CSI编码比特可能都跟信道信息有关，其重要性都是平等的，如果丢弃掉部分比特，可能导致基站不能恢复压缩后的信道，也会导致解码器的输入维度发生变化，从而导致解码器不能很好地解码。因此，和相关技术相比，本申请实施例提出的信道状态信息反馈方法，可以有效地解决一个上行传输资源不能有效传输至少一个信道状态信息的问题；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。
图3为本申请实施例提供的信道状态信息反馈方法的第三流程示意图。基于上述技术方案进行优化与扩展，并可以与上述可选实施方式进行结合。如图3所示，信道状态信息反馈方法可以包括以下步骤：
S301、将第一信道状态信息分成至少两个子信道状态信息。
S302、在第一时隙上反馈第一子信道状态信息；在第二时隙上反馈第二子信道状态信息；其中，第二时隙大于第一时隙。
在一个实施例中，终端可以在第一时隙上反馈第一子信道状态信息；在第二时隙上反馈第二子信道状态信息；其中，第二时隙大于第一时隙；第二时隙根据第一时隙和时隙偏置t 确定；或者，时隙偏置t根据第二时隙和第一时隙确定；或者，第一时隙根据第二时隙和时隙偏置t确定；时隙偏置t为正整数。
在一个实施例中，时隙偏置t为大于等于第一门限m1，小于等于第二门限m2的整数，m1和m2为正整数，且m1小于m2。例如，终端可以在第n个时隙上反馈第一子信道状态信息；在第n+t个时隙上反馈第二子信道状态信息；其中，n为整数；t为大于等于m1且小于等于m2的正整数；m1和m2为正整数。
在一个实施例中，第一门限m1的确定方式包括以下之一：根据接收的第一指示信令确定；根据约定的方式确定；根据第一时间间距f1和载波间距确定；根据处理CSI的能力确定；其中，第一指示信令可以包括第一高层信令和/或第一物理层信令。示例性地，第一门限m1可以由基站确定，终端接收基站发送的第一高层信令和/或第一物理层信令，终端通过第一高层信令和/或第一物理层信令确定m1；或者，第一门限m1还可以由基站和终端根据约定的方式确定；或者，m1还可以由根据第一时间间距f1和载波间距确定；其中，f1为承载第一CSI报告的第一上行传输资源的最后一个符号到承载第二CSI报告的第二上行传输资源的第一个符号之间的符号个数，所述f1为满足基站处理CSI报告的最小时间；或者，第一门限m1还可以根据终端处理CSI的能力确定，终端向基站反馈处理CSI的能力，基站根据终端处理CSI的能力确定m1。
在一个实施例中，第二门限m2的确定方式包括以下之一：根据接收的第二指示信令确定；根据约定的方式确定；根据第二时间间距f2和载波间距确定；根据处理CSI的能力确定；其中，第二指示信令可以包括第二高层信令和/或第二物理层信令。示例性地，第二门限m2可以由基站确定，终端接收基站发送的第二高层信令和/或第二物理层信令，终端可以通过第二高层信令和/或第二物理层信令确定m2；或者，第二门限m2还可以由基站和终端根据约定的方式确定；或者，第二门限m2还可以根据第二时间间距f2和载波间距确定；f2为承载第一CSI报告的第一上行传输资源的最后一个符号到承载第二CSI报告的第二上行传输资源的第一个符号之间的符号个数，所述f2为信道保持相关性要求的最大时间；或者，第二门限m2还可以根据终端处理CSI的能力确定，终端向基站反馈处理CSI的能力，基站根据终端处理CSI的能力确定m2。
在一个实施例中，时隙偏置t小于第一门限m1，即1≤t＜m1，第一子信道状态信息对应的第一信道状态信息报告和第二子信道状态信息对应的第二信道状态信息报告对应的混合自动重复请求(Hybrid Automatic Repeat Request，简称HARQ)HARQ具有相同的HARQ ID。
在一个实施例中，时隙偏置t大于第一门限m1，即，第一信道状态信息报告和第二信道状态信息报告对应的HARQ具有相同的HARQ ID；或者，第一信道状态信息报告和第二信道状态信息报告对应的HARQ具有不同的HARQ ID。
在一个实施例中，时隙偏置t大于第二门限m2，即，终端可以忽略第二子信道状态信息对应的第二信道状态信息报告。即不在第二上行传输资源上反馈第二子信道状态信息对应的 第二信道状态信息报告。
在一个示例中，时隙偏置t大于等于第二门限m2，即t≥m2，终端还可以接收第三指示信令，重新获取第一信道状态信息，第一信道状态信息为第二类预编码信息，反馈第一信道状态信息，所述第三指示信令为高层和/或物理层信令。在一个示例中，终端还可以接收第四指示信令，重新获取第一信道状态信息，第一信道状态信息为第一类预编码信息，反馈第一信道状态信息，所述第四指示信令为高层和/或物理层信令。在一个示例中，终端还可以接收第五指示信令，重新获取第一子信道状态信息和第二子信道状态信息，反馈子第一信道状态信息和第二子信道状态信息，所述第五指示信令为高层和/或物理层信令。在一个示例中，终端还可以接收第六指示信令，重新获取第一子信道状态信息，反馈第一子信道状态信息，所述第六指示信令为高层和/或物理层信令。在一个示例中，终端还可以接收第七指示信令，重新获取第二子信道状态信息，反馈第二子信道状态信息，所述第七指示信令为高层和/或物理层信令。
在一个实施例中，第二上行传输资源可以为PUSCH，第二上行传输资源的有效传输比特大于第二子信道状态信息对应的比特数。
在一个实施例中，第二上行传输资源可以为PUCCH，且第二上行传输资源的有效传输比特大于第二子信道状态信息对应的保留比特。
在一些实施例中，一个上行传输资源的有效传输比特是指所述上行传输资源在它对应的调制编码方式下能承载的传输比特数目。
在一个实施例中，第二上行传输资源可以为PUCCH，所述PUCCH用于传输第二信道状态信息，这里第二信道状态信息为不同于第一信道状态信息的一个信道状态信息，降低第二信道状态信息的传输优先级以传输第二子信道状态信息。
图4为本申请实施例提供的上行传输资源的结构示意图。如图4所示，终端可以在第n个时隙上反馈第一子信道状态信息，在第n+t个时隙上反馈第二子信道状态信息，其中n为整数，t为正整数，n在当前时隙之前为负整数，在当前时隙之后为正整数。在一个示例中，由于基站需要在接收CSI1后，对接收的CSI1处理需要一定的时间，所以，要求t≥m1，其中m1跟基站使用处理CSI1的算法或者基站自身的处理能力有关，也跟基站需要同时处理的CSI个数有关。在一个示例中，第一门限m1可以由基站确定，基站将m1通过第一高层信令和/或第一物理层信令发送给终端，终端通过接收第一高层信令和/或第一物理层信令确定m1。在一个示例中，第一门限m1为基站和终端约定的，比如根据基站的处理能力或者终端的处理能力不同有不同的m1。在一个示例中，第一门限m1为基站和终端约定的一个最小值，比如基站和终端约定，承载第一CSI报告的第一上行传输资源的最后一个符号到承载第二CSI报告的第二上行传输资源的第一个符号之间的符号个数为f1，那么m1为floor(f1/s)，其中f1为正整数，s为每个时隙中包括的符号个数，比如为12、14等正整数，floor表示取整函数，比如上取整函数或下取整函数。在一个示例中，第一门限m1根据f1和载波间距确定，比如 为2(u1/u2)×floor(f1/s)，其中，f1为正整数，s为每个时隙中包括的符号个数，u1为第一上行传输资源或第二上行传输资源对应的子载波间距相关的参数，比如为30千赫兹(khz)等；u2对应参考子载波间距，比如为15khz。在一个示例中，第一门限m1与终端处理CSI的能力有关，如果m1太小，终端还来不及获得CSI，所以第一门限m1必须大于一定的值。第一门限m1还可以根据终端处理CSI的能力确定，终端反馈处理CSI的能力给基站，基站通过终端处理CSI的能力来确定m1的值。
在一个实施例中，由于信道是不断变化的，信道状态信息有一定的时效性，大于一定的时效后，终端再反馈CSI已经没有意义了。所以，需要规定时隙偏置t小于或者等于第二门限m2。在一个示例中，m2为正整数，第二门限m2可以根据终端处理CSI的能力确定。在一个示例中，终端可以根据下行信道的变化情况确定m2的值，比如变化快的信道m2小，而变化慢的信道m2大，信道的变化快慢与终端的移动速度有关，与周围的散射体有关，也与子载波间距有关。在一个示例中，基站确定m2，比如根据信道的变化快慢确定m2，根据统计的信道特征确定m2，并将确定的m2通过第二高层信令和/或第二物理层信令指示给终端。在一个示例中，m2为基站和终端约定的一个最大值，比如基站和终端约定，承载第一CSI报告的第一上行传输资源的最后一个符号到承载第二CSI报告的第二上行传输资源的第一个符号之间的符号个数为f2，那么m2为floor(f2/s)，其中f2为正整数，s为每个时隙中包括的符号个数，比如为12、14等正整数，floor表示取整函数，比如上取整函数或下取整函数。在一个示例中，第二门限m2可以根据第二时间间距f2和载波间距确定，比如m2为2(u1/u2)×floor(f2/s)；其中f2为正整数，s为每个时隙中包括的符号个数，u1为第一上行传输资源或第二上行传输资源对应的子载波间距相关的参数，比如为30khz等，u2对应参考子载波间距，比如为15khz。
在一个实施例中，时隙偏置t小于第一门限m1，即1≤t＜m1，终端可以不处理或者传输第二子信道状态信息。在一个示例中，如果1≤t＜m1，终端可以获取第二子信道状态信息，并在第二上行传输资源上传输第二子信道状态信息；其中，第一子信道状态信息对应的第一信道状态信息报告和第二子信道状态信息对应的第二信道状态信息报告对应的HARQ具有相同的HARQ ID，即它们是在同一个上行传输资源重传。在一个示例中，时隙偏置t大于等于第一门限m1，即t≥m1，终端可以获取第二信道状态信息，并在第二上行传输资源上传输第二信道状态信息。
在一个示例中，时隙偏置t大于等于第二门限m2，即t≥m2，终端可以不反馈第二子信道状态信息。在一个示例中，t≥m2，终端可以在第二上行传输资源中反馈第二子信道状态信息。但基站在接收第二子信道状态信息后，发现t≥m2，基站可以不处理第二子信道状态信息。在一个示例中，基站在接收第二子信道状态信息后，发现t≥m2，不处理第二子信道状态信息，并且忽略已经处理的第一子信道状态信息。在一个示例中，基站在接收第二子信道状态信息后，发现t≥m2，不处理第二子信道状态信息，并且通过第一子信道状态信息获得终端对应的低精度的信道状态信息。
在一个示例中，基站在接收到第二子信道状态信息后，发现t≥m2，向终端发送一个第三指示信令，用于指示终端重新获取第一信道状态信息，第一信道状态信息为第二类预编码信息，接收第一信道状态信息，所述第三指示信令为高层和/或物理层信令。
在一个示例中，基站在接收到第二子信道状态信息后，发现t≥m2，向终端发送一个第四指示信令，用于指示终端重新获取第一信道状态信息，第一信道状态信息为第一类预编码信息，接收第一信道状态信息，所述第四指示信令为高层和/或物理层信令。
在一个示例中，基站在接收到第二子信道状态信息后，发现t≥m2，向终端发送一个第五指示信令，用于指示终端重新获取第一子信道状态信息和第二子信道状态信息，接收第一子信道状态信息和第二子信道状态信息，所述第五指示信令为高层和/或物理层信令。
在一个示例中，基站在到接收第二子信道状态信息后，发现t≥m2，向终端发送一个第六指示信令，用于指示终端重新获取第一子信道状态信息，接收第一子信道状态信息，所述第六指示信令为高层和/或物理层信令。
在一个示例中，基站在接收到第二子信道状态信息后，发现t≥m2，向终端发送一个第七指示信令，用于指示终端重新获取第二子信道状态信息，接收第二子信道状态信息，所述第七指示信令为高层和/或物理层信令。
图5为本申请实施例提供的信道状态信息接收方法的流程示意图，该方法可以由信道状态信息接收装置或者基站来执行，该装置或者基站可以由软件和/或硬件的方式实现，该装置或基站可以集成在任何具有网络通信功能的智能设备中。如图5所示，信道状态信息接收方法可以包括以下步骤：
S501、在至少两个上行传输资源上接收至少两个子信道状态信息。
S502、将该至少两个子信道状态信息合并成第一信道状态信息。
在一个示例中，第一上行传输资源传输的子信道状态信息和第二上行传输资源传输的子信道状态信息的交集为零，或者互不相同。
在一个示例中，第一上行传输资源传输的子信道状态信息和第二上行传输资源传输的子信道状态信息的并集为所有的子信道状态信息。
在一个实施例中，基站可以在第一上行传输资源上接收第一子信道状态信息；在第二上行传输资源上接收第二子信道状态信息；其中，该至少两个子信道状态信息包括：第一子信道状态信息和第二子信道状态信息。
在一个实施例中，第一上行传输资源和第一子信道状态信息对应第一信道状态信息报告；第二上行传输资源和第二子信道状态信息对应第二信道状态信息报告。
在一个实施例中，基站可以接收第一时隙反馈的第一子信道状态信息；接收第二时隙反馈的第二子信道状态信息；其中，第二时隙大于第一时隙。这里的时隙也可以是子时隙。
在一个实施例中，第二时隙根据第一时隙和时隙偏置t确定，比如，第二时隙等于第一时隙加上时隙偏置；其中，时隙偏置t为正整数。
在一个实施例中，时隙偏置t根据第二时隙和第一时隙确定，比如，时隙偏置等于第二时隙减去第一个时隙；其中，时隙偏置t为正整数。
在一个实施例中，第一时隙根据第二时隙和时隙偏置t确定，比如，比如第一时隙等于第二时隙减去时隙偏置；其中，时隙偏置t为正整数。
例如，基站可以接收第n个时隙反馈的第一子信道状态信息；接收第n+t时隙反馈的第二子信道状态信息；其中，n为整数；t为大于等于m1且小于等于m2的正整数；m1和m2为正整数。
在一个实施例中，时隙偏置t为大于等于第一门限m1，小于等于第二门限m2的整数，m1和m2为正整数，且m1小于m2。
在一个实施例中，第一门限m1的确定方式包括以下之一：根据发送的第一指示信令确定；根据约定的方式确定；根据第一时间间距f1和载波间距确定；根据终端处理CSI的能力确定。
在一个实施例中，第二门限m2的确定方式包括以下之一：根据发送的第二指示信令确定；根据约定的方式确定；根据第二时间间距f2和载波间距确定；根据终端处理CSI的能力确定。
在一个实施例中，时隙偏置t小于第一门限m1，第一信道状态信息报告和第二信道状态信息报告对应的HARQ具有相同的HARQ ID。
在一个实施例中，时隙偏置t大于等于第一门限m1，第一信道状态信息报告和第二信道状态信息报告对应的HARQ具有相同的HARQ ID；或者，第一信道状态信息报告和第二信道状态信息报告对应的HARQ具有不同的HARQ ID。
在一个示例中，时隙偏置t大于等于第二门限m2，基站还可以发送第三指示信令，用于指示终端重新获取第一信道状态信息，第一信道状态信息为第二类预编码信息，接收第一信道状态信息，所述第三指示信令为高层和/或物理层信令。
在一个示例中，时隙偏置t大于等于第二门限m2，基站还可以发送第四指示信令，用于指示终端重新获取第一信道状态信息，第一信道状态信息为第一类预编码信息，接收第一信道状态信息，所述第四指示信令为高层和/或物理层信令。
在一个示例中，时隙偏置t大于等于第二门限m2，基站还可以发送第五指示信令，用于指示终端重新获取第一子信道状态信息和第二子信道状态信息，接收第一子信道状态信息和第二子信道状态信息，所述第五指示信令为高层和/或物理层信令。

在一个实施例中，第二上行传输资源为PUSCH，第二上行传输资源的有效传输比特大于第二子信道状态信息对应的比特数。
在一个实施例中，第二上行传输资源为PUCCH，且第二上行传输资源的有效传输比特大于第二子信道状态信息对应的比特数。
在一个实施例中，第二上行传输资源为PUCCH，PUCCH为用于传输静态HARQ码本的保留比特。
在一些实施例中，一个上行传输资源的有效传输比特是指所述上行传输资源在它对应的调制编码方式下能承载的传输比特数目。
在一个实施例中，第二上行传输资源可以为PUCCH，所述PUCCH用于传输第二信道状态信息，这里第二信道状态信息为不同于第一信道状态信息的一个信道状态信息，降低第二信道状态信息的传输优先级以传输第二子信道状态信息。
本申请实施例提出的信道状态信息接收方法，基站在至少两个上行传输资源上接收至少两个子信道状态信息；将该至少两个子信道状态信息合并成第一信道状态信息。而在相关技术中，终端通过丢弃部分CSI比特来达到传输的目的，但对于基于AI的CSI来说，每个CSI编码比特可能都跟信道信息有关，其重要性都是平等的，如果丢弃掉部分比特，可能导致基站不能恢复压缩后的信道，从而导致解码器不能很好地解码。因此，和相关技术相比，本申请实施例提出的信道状态信息接收方法，可以有效地解决一个上行传输资源不能有效传输至少一个信道状态信息的问题；并且，本申请实施例的技术方案实现简单方便、便于普及，适用范围更广。
