技术领域
本申请属于通信技术领域，具体涉及一种CQI传输方法、装置、终端及网络侧设备。
背景技术
对于多天线***，发送端可以根据信道状态信息(channel state information，CSI)优化信号的发送，使其更加匹配信道的状态。如：发送端根据CSI中的信道质量指示(channel quality indicator，CQI)可以选择合适的调制编码方案(modulation and coding scheme，MCS)实现链路自适应；根据CSI中的预编码矩阵指示(precoding matrix indicator，PMI)，可以实现特征波束成形(eigen beamforming)，从而最大化接收信号的强度，或者用来抑制干扰，例如小区间干扰、多用户之间干扰等。因此，自从多天线技术(multi-input multi-output，MIMO)被提出以来，如何获取CSI一直都是研究热点。
相关技术中，基于人工智能(Artificial Intelligence，AI)模型的CSI反馈方案为：终端将信道信息输入至编码网络后得到编码结果，将编码结果传输至基站；基站接收到编码结果后，将编码结果输入到解码网络中，得到恢复的信道信息。
然而，相关技术中终端通常只存储有压缩模型，而没有解压缩模型，或者终端的解压缩模型和基站的不同，终端无法获知基站恢复的信道信息，只能使用压缩编码前的信道信息确定CQI，并将CQI传输至基站，这会导致基站接收到的CQI和恢复的信道信息不匹配。
因此，终端如何传输与基站恢复的信道信息相匹配的CQI是亟待解决的问题。

为了便于更加清晰地理解本申请各实施例，首先对一些相关的背景知识进行如下介绍。
通常，基站在某个slot的某些时频资源上发送CSI参考信号(CSI Reference Signal，CSI-RS)，终端根据CSI-RS进行信道估计，计算这个slot上的信道信息，通过码本将PMI反馈给基站，基站根据终端反馈的码本信息组合出信道信息，在下一次CSI上报之前，基站以此进行数据预编码及多用户调度。
也就是说，传统的基于码本的CSI反馈，终端将预编码矩阵投影在选择的正交基上，将较强的系数上报给基站，终端可以根据上报的内容计算出基站恢复的预编码矩 阵，使用恢复后的预编码矩阵计算信噪比得到CQI，从而使CQI与上报的预编码矩阵对应。
为了进一步减少CSI反馈开销，终端可以将每个子带上报PMI改成按照延迟(delay)上报PMI，由于delay域的信道更集中，用更少的delay的PMI就可以近似表示全部子带的PMI，即将delay域信息压缩之后再上报。
同样，为了减少开销，基站可以事先对CSI-RS进行预编码，将编码后的CSI-RS发送至终端，终端看到的是经过编码之后的CSI-RS对应的信道，终端只需要在网络侧指示的端口中选择若干个强度较大的端口，并上报这些端口对应的系数即可。
进一步，为了更好的压缩信道信息，可以使用神经网络或机器学习的方法。
人工智能目前在各个领域获得了广泛的应用。AI模块有多种实现方式，例如神经网络、决策树、支持向量机、贝叶斯分类器等。本申请以神经网络为例进行说明，但是并不限定AI模块的具体类型。
基于AI模型对CSI进行压缩恢复的流程为：终端估计CSI-RS，计算信道信息，将计算的信道信息或者原始的估计到的信道信息通过编码网络得到编码结果，将编码结果发送给基站，基站接收编码后的结果，输入到解码网络中，恢复信道信息。
具体的，基于神经网络(即AI模型)的CSI压缩反馈方案是：在终端利用编码网络对信道信息进行压缩编码，将压缩后的内容发送给基站，在基站利用解码网络对压缩后的内容进行解码，从而恢复信道信息，此时基站的解码网络和终端的编码网络需要联合训练，达到合理的匹配度。编码模型的输入是信道信息，输出是编码信息，解码模型的输入是编码信息，输出是信道信息。其中，编码网络和解码网络可以通过以下三种方式训练得到：
方式一：神经网络是通过终端的编码器和基站的解码器组成联合的神经网络，由网络侧进行联合训练，训练完成之后，基站将编码器网络发送给终端。
方式二：终端和基站各自训练各自的编码网络和解码网络，通过匹配过程进行匹配，使得终端的编码网络和基站的解码网络相互匹配。
方式三：终端训练编码模型和解码模型，基站根据原始数据和终端的编码结果训练解码模型，此时基站不需要训练编码模型
然而，在基于AI模型传输CSI中CQI的过程中，无论是基站训练网络模型将编码部分发送给终端，还是终端和基站各自训练编码和解码部分，然后进行匹配，都可能出现终端不知道基站的解码模型，即终端无法计算基站恢复的信道信息，只能使用压缩编码前的信道信息确定CQI，并将CQI传输至基站，这会导致基站接收到的CQI和恢复的信道信息不匹配，即CQI明显偏高。
因此，终端如何传输与基站恢复的信道信息相匹配的CQI是亟待解决的问题。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的CQI传输方法进行详细地说明。
在本申请实施例中，终端基于第一信道信息及目标消息，确定第二信道信息对应的目标CQI，实现了终端可以在无法获知第一网络侧设备恢复的第二信道信息的情况下，确定第二信道信息对应的目标CQI，进而将目标CQI发送至第一网络侧设备，保证上报的目标CQI与第二信道信息匹配，能够降低调度误差。
图2是本申请实施例提供的CQI传输方法的流程示意图之一，如图2所示，该方法包括步骤201-202。
步骤201、终端基于第一信道信息及目标消息，确定第二信道信息对应的目标CQI。
其中，所述目标消息用于辅助所述终端确定所述目标CQI；所述第二信道信息为所述第一网络侧设备将信道特征信息输入至第二模型后得到的信息；所述信道特征信息为所述终端将所述第一信道信息输入至第一模型后得到的信息。
需要说明的是，本申请实施例可应用于CQI传输的场景中。所述终端包括但不限于上述所列举的终端11的类型，本申请对此并不限定；所述第一网络侧设备包括但不限于上述所列举的网络侧设备12的类型，本申请对此并不限定。
由于在基于AI模型传输CQI的过程中，终端无法获得第一网络侧设备(例如基站)恢复的信道信息(即第二信道信息)，因此终端只能使用压缩编码前的信道信息(即第一信道信息)确定CQI，并将CQI传输至基站，这会导致基站接收到的CQI和恢复的信道信息不匹配，即CQI明显偏高。所述目标消息用于辅助所述终端在无法获知所述第二信道信息的情况下确定所述目标CQI。
其中，第二信道信息为第一网络侧设备将信道特征信息输入至第二模型后得到的信息；信道特征信息为终端将第一信道信息输入至第一模型后得到的信息。
可选地，所述第一信道信息，包括：所述终端估计到的信道信息；或者，所述终端对于估计到的信道信息进行计算后得到的预编码矩阵。
为了向第一网络侧设备传输与第二信道信息对应的目标CQI，在本申请实施例中，终端需要基于第一网络侧设备发送的CSI-RS进行信道估计，得到第一信道信息；在得到第一信道信息之后，终端基于第一信道信息及来自第一网络侧设备的目标消息，可以确定出第二信道信息对应的目标CQI。也就是说，终端即使在无法获知第二信道信息的情况下，也能够根据第一信道信息及目标消息，确定出与第二信道信息相对应的目标CQI。
可选地，所述目标消息包括以下至少一项：
a)第一信息，用于辅助所述终端基于所述第一信道信息的SINR，确定所述第二信道信息的SINR；
b)第二信息，用于辅助所述终端确定随机矩阵；所述随机矩阵用于所述终端基于所述第一信道信息确定所述目标CQI；
c)第三信息，用于辅助所述终端基于所述第一信道信息对应的CQI，确定所述目标CQI；
d)目标模型；
e)第四信息，用于指示所述终端将所述第一信道信息对应的CQI，确定为所述目标CQI；
f)第五信息，用于指示所述终端基于目标映射关系确定所述目标CQI；所述目标映射关系包括SINR和CQI的对应关系。
步骤202、所述终端向第一网络侧设备发送所述目标CQI。
在本实施例中，终端在基于第一信道信息及目标消息，确定出目标CQI之后，便向第一网络侧设备发送目标CQI。
本申请实施例提供的CQI传输方法中，终端基于第一信道信息及目标消息，确定第二信道信息对应的目标CQI，实现了终端可以在无法获知第一网络侧设备恢复的第二信道信息的情况下，确定第二信道信息对应的目标CQI，进而将目标CQI发送至第一网络侧设备，保证上报的目标CQI与第二信道信息匹配，能够降低调度误差。
可选地，所述第一信息包括以下至少一项：
a)信干噪比SINR回退值；
b)功率比例；
c)幅度比例。
可选地，在所述第一信道信息为多秩rank的预编码矩阵的情况下，所述第一信息与多rank的预编码矩阵的layer对应，和/或，所述第一信息与多rank的预编码矩阵的rank对应。
可选地，所述终端基于第一信道信息及目标消息，确定第二信道信息对应的目标CQI，具体可以通过以下至少一种方式实现：
方式1、具体包括以下步骤[1]-步骤[2]：
步骤[1]、在所述目标消息包括所述第一信息的情况下，所述终端基于所述第一信道信息的SINR和所述第一信息，确定所述第二信道信息的SINR；
步骤[2]、所述终端基于所述第二信道信息的SINR确定所述目标CQI。
方式2、具体包括以下步骤[1]-步骤[3]：
步骤[1]、在所述目标消息包括所述第二信息的情况下，所述终端基于所述第二信息，确定所述随机矩阵；
步骤[2]、所述终端基于所述随机矩阵和所述第一信道信息，确定第三信道信息；
步骤[3]、所述终端基于所述第三信道信息的SINR，确定所述目标CQI。
方式3、在所述目标消息包括所述第三信息的情况下，所述终端基于所述第一信道信息对应的CQI和所述第三信息，确定所述目标CQI。

方式5、在所述目标消息包括所述第四信息的情况下，所述终端将所述第一信道信息对应的CQI，确定为所述目标CQI。
方式6、在所述目标消息包括所述第五信息的情况下，所述终端基于所述目标映射关系及所述第一信道信息的SINR，确定所述目标CQI。
这里，针对方式1-方式6分别进行说明：
方式1、具体包括以下步骤[1]-步骤[2]：
步骤[1]、在所述目标消息包括所述第一信息的情况下，所述终端基于所述第一信道信息的SINR和所述第一信息，确定所述第二信道信息的SINR；
步骤[2]、所述终端基于所述第二信道信息的SINR确定所述目标CQI。
在本申请实施例中，在第一信息包括信干噪比SINR回退值的情况下，终端需要基于第一信道信息的SINR和SINR回退值，确定等效的第二信道信息的SINR；然后基于第二信道信息的SINR确定目标CQI。
具体地，终端在计算出第一信道信息的SINR之后，需要减去SINR回退值，得到第二信道信息的SINR，基于第二信道信息的SINR，通过查询CQI表格，即可量化得到目标CQI，其中，CQI表格中有第二信道信息的SINR与目标CQI之间的映射关系。
例如：终端计算得到第一信道信息的SINR为10dB，基站指示的SINR回退值为2dB，则终端确定第二信道信息的SINR为8dB，实际上报的目标CQI是8dB SINR对应的CQI。
在第一信息包括功率比例或幅度比例的情况下，终端需要基于第一信道信息的SINR和功率比例或幅度比例，确定第二信道信息的SINR；然后基于第二信道信息的SINR确定目标CQI。
具体地，终端在计算出第一信道信息的SINR之后，需要乘以功率比例或幅度比例，得到第二信道信息的SINR；基于第二信道信息的SINR，通过查询CQI表格，即可量化得到目标CQI。
例如：终端计算得到第一信道信息的SINR为20dB，对应的线性值100，基站指示的功率比例为0.8，则终端确定第二信道信息的SINR为80，即19dB；或者，基站指示的幅度比例为0.9，则终端确定第二信道信息的SINR为81，也约为19dB；则终端实际上报的目标CQI是19db SINR对应的CQI。
需要说明的是，在第一信道信息为多秩rank的预编码矩阵的情况下，预编码矩阵每个层(layer)的功率因子或幅度因子可以不同，根据AI模型对每个layer的恢复效果确定，基站可以按layer指示；不同rank的调整因此可以不同，例如rank1使用0.9，rank2使用0.8。
在上述实施方式中，在目标消息包括第一信息的情况下，终端基于第一信道信息的SINR和第一信息，实现了即使在无法获知第二信道信息的情况下，也能够确定出与第二信道信息相对应的目标CQI。
方式2、具体包括以下步骤[1]-步骤[3]：
步骤[1]、在所述目标消息包括所述第二信息的情况下，所述终端基于所述第二信息，确定所述随机矩阵；
步骤[2]、所述终端基于所述随机矩阵和所述第一信道信息，确定第三信道信息；
步骤[3]、所述终端基于所述第三信道信息的SINR，确定所述目标CQI。
可选地，所述第二信息包括以下至少一项：
a)功率比例；
b)幅度比例；
c)随机扰动值；
d)所述第一信道信息和所述第二信道信息的相似度。
例如，相似度可以是余弦相似度、归一化均方误差(normalized mean squared error，NMSE)、其他任何描述两个矩阵关系的度量标准，或者是表示相似程度的一个等级；本申请对相似度的描述方法不作具体限定。
在本申请实施例中，在第二信息包括功率比例或幅度比例的情况下，终端需要基于功率比例或幅度比例，确定随机矩阵；然后基于随机矩阵和第一信道信息的SINR，确定第三信道信息，最后基于第三信道信息的SINR，根据对应的调制方式、码率及谱效率，查表获得SINR对应的目标CQI。
具体地，终端需要基于功率比例或幅度比例生成一个随机矩阵，并根据第一信道信息的SINR及随机矩阵，得到与第二信道信息等效的第三信道信息，基于第三信道信息的SINR，确定目标CQI。
在第二信息包括随机扰动值或第一信道信息和第二信道信息的相似度的情况下，终端需要基于随机扰动值或第一信道信息和第二信道信息的相似度，确定随机矩阵，然后基于随机矩阵和第一信道信息，确定第三信道信息，最后基于第三信道信息的SINR，确定目标CQI。
具体地，终端需要根据随机扰动值或第一信道信息和第二信道信息的相似度，生成一个随机矩阵作用于第一信道信息，得到与第二信道信息等效的第三信道信息(例 如等效的信道矩阵或预编码矩阵)，然后使用这个等效的第三信道信息计算对应的SINR并量化为目标CQI。
例如，第一信道信息是预编码矩阵，基站指示第一信道信息和第二信道信息的相似度为0.9，终端随机生成一个维度与预编码矩阵相同，服从均值为0，方差(即随机扰动值)为0.1的复高斯随机矩阵，与原始的第一信道信息(即预编码矩阵)相加之后经过归一化得到等效的预编码矩阵(即第三信道信息)，计算对应的SINR，最后基于第三信道信息的SINR，确定目标CQI。
需要说明的是，本申请对随机扰动的公式不做限定，可以是协议约定的，也可以是终端实现。本申请对随机矩阵的行为也不做限定，终端根据基站指示的相关性和第一信道信息确定一个第三信道信息，然后计算第三信道信息的SINR。
需要说明的是，在第二信道信息为多秩rank的预编码矩阵的情况下，预编码矩阵每个层(layer)的随机扰动值或相似度可以不同，根据AI模型对每个layer的恢复效果确定，基站可以按layer指示；不同rank的调整因此可以不同，例如rank1使用0.9，rank2使用0.8。
在上述实施方式中，在目标消息包括第二信息的情况下，终端基于第二信息，确定随机矩阵；基于随机矩阵和第一信道信息，确定第三信道信息，最后基于第三信道信息的SINR，确定目标CQI，实现了终端在无法获知第二信道信息的情况下，也能够确定出与第二信道信息相对应的目标CQI。
方式3、在所述目标消息包括所述第三信息的情况下，所述终端基于所述第一信道信息对应的CQI和所述第三信息，确定所述目标CQI。
在本申请实施例中，第三信息用于辅助终端基于第一信道信息对应的CQI，确定目标CQI。
可选地，所述第三信息包括：CQI回退值或CQI补偿值，其中，CQI补偿值可以为正数，也可以为负数。
具体地，在第一网络侧设备(例如基站)指示的目标消息包括CQI补偿值的情况下，终端需要计算第一信道信息的SINR，查询CQI表格可以得到第一信道信息的CQI；然后用第一信道信息的CQI加上CQI补偿值，即可确定目标CQI。
具体地，在第一网络侧设备(例如基站)指示的目标消息包括CQI回退值的情况下，终端需要计算第一信道信息的SINR，查询CQI表格可以得到第一信道信息的CQI；然后用第一信道信息的CQI减去CQI回退值，即可确定目标CQI。
例如：终端计算出第一信道信息的SINR之后，查询CQI表格得到第一信道信息的CQI为23，基站指示的CQI回退值为3，则终端上报的目标CQI为20。
在上述实施方式中，在目标消息包括第三信息的情况下，终端基于第一信道信息对应的CQI和第三信息，实现了终端在无法获知第二信道信息的情况下，也能够确定出与第二信道信息相对应的目标CQI。
方式4、在所述目标消息包括所述目标模型的情况下，所述终端使用所述目标模型对所述信道特征信息进行解码后，将基于解码得到的信道信息对应的CQI，确定为所述目标CQI。
在本申请实施例中，目标模型为一个公共解码网络，该公共解码网络可以是第一网络侧设备指示的，也可以是协议约定的、或终端自己训练的。
终端使用这个公共解码网络对信道特征信息进行解码，得到解码后的信道信息，将该信道信息的SINR对应的CQI确定为目标CQI。
方式5、在所述目标消息包括所述第四信息的情况下，所述终端将所述第一信道信息对应的CQI，确定为所述目标CQI。
在本申请实施例中，第四信息用于指示终端将第一信道信息对应的CQI，确定为目标CQI。
例如，基站向终端发送第四信息，指示终端使用压缩编码前的第一信道信息计算CQI，并将第一信道信息对应的CQI，确定为目标CQI，即不做补偿。
方式6、在所述目标消息包括所述第五信息的情况下，所述终端基于所述目标映射关系及所述第一信道信息的SINR，确定所述目标CQI。
在本申请实施例中，第五信息，用于指示终端基于目标映射关系确定目标CQI；其中，目标映射关系包括SINR和CQI的对应关系，该目标映射关系可以是协议约定的固定的映射关系。
例如：基站指示终端使用新的CQI表格(即目标映射关系)进行CQI查表，通过表格进行补偿，从而确定目标CQI。需要说明的是，目标映射关系是指CQI和调制方式、码率及谱效率之间的关系，终端通过SINR计算对应的谱效率在满足误块率(Block Error Ratio，BLER)条件下选择对应的CQI。
可选地，所述目标消息与用户对应；和/或，所述目标消息与所述第二模型对应。
在本实施例中，第一网络侧设备(例如基站)给每个用户指示的目标消息可以是独立的，即目标消息与用户对应；
如果基站使用一个公共的解码器作为第二模型，可以对每个用户指示相同的目标消息，即目标消息与第二模型对应。
可选地，终端获取目标消息的方式包括以下至少一项：
方式1、所述终端接收所述第一网络侧设备或第二网络侧设备发送的所述目标消息。
例如：第一网络侧设备可以通过广播信道传递目标消息(例如CQI回退值)与第二模型ID的对应关系，终端根据对应的第二模型确定CQI回退值。
可选地，所述第二网络侧设备包括以下至少一项：
a)基站；

步骤2、所述终端基于所述目标消息与第二模型的对应关系及所述第二模型的标识，获取所述目标消息。
在多用户的情况下，第一网络侧设备或第二网络侧设备向每个终端发送目标消息与第二模型的对应关系及第二模型的标识，各终端基于目标消息与第二模型的对应关系及第二模型的标识，即可获取目标消息。
可选地，所述目标消息承载于以下至少一项：
a)下行控制信息DCI；

具体地，对于周期或半持续的CSI上报，在CSI报告配置(CSI-reportConfig)中配置目标消息，后续所有的CSI上报，只要是基于AI模型的CSI上报，都使用目标消息对应的方式确定目标CQI；
对于非周期的CSI上报，可以在每次的CSI-reportConfig中配置目标消息，也可以使用DCI或MACCE直接向终端指示目标消息。
c)无线资源控制RRC。
具体地，通过RRC信令直接配置目标消息，无论周期，半持续，非周期CSI，只要是终端上报第一模型压缩的信道特征信息(例如PMI)的时候，终端都使用目标消息对应的方式确定目标CQI。
可选地，终端将目标CQI发送至第一网络侧设备之后，第一网络侧设备还需要对目标消息进行更新，因此，终端还需执行以下至少一项步骤：
a)所述终端基于网络指示向所述第一网络侧设备或所述第二网络侧设备发送所述第一信道信息和/或CSI标识。
具体地，所述终端基于网络指示向所述第一网络侧设备或所述第二网络侧设备发送所述第一信道信息。
或者，所述终端基于网络指示向所述第一网络侧设备或所述第二网络侧设备发送所述第一信道信息和CSI标识。
