为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
LTE/NR系统中的资源调度和链路自适应策略完全由基站控制，基站通过上行CQI或下行CQI的值为UE选择合适的调制编码方式等级，以达到根据信道质量信息使系统吞吐量最优的目的。可理解的，调制编码方式等级能够指示调制方式和编码速率。
对于上行CQI，即基站测量得到的CQI，基站通过探测参考信号(Sounding Reference Signal，SRS)测量得到表征链路质量信息的信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)的值，然后根据SINR值来计算CQI的值，并根据CQI的值为UE选择合适的频域资源及调制编码方式等级。如图2A所示，基站210通过物理层211测量得到SRS测量结果，将SRS测量结果发送至媒体接入控制(Medium Access Control，MAC)层212，MAC层212基于SRS测量结果得到CQI的值，并基于CQI的值确定调制编码方式等级、时频资源位置和冗余版本(Redundancy Version，RV)版本号。可选地，物理层211还向MAC层212上报循环冗余校验(Cyclic Redundan cy Check，CRC)校验信息。
对于下行CQI，即终端计算得到的CQI，终端首先计算CQI的值，并通过上行信道反馈至基站，然后基站根据反馈的CQI的值来为UE选择合适的频域资源，调制编码方式等级和传输模式。如图2B所示，UE220的物理层221计算CQI值，并将CQI值发送至基站210的物理层211，物理层211将接收到的CQI值发送至MAC层212，MAC层212根据UE反馈的CQI值为UE220选择以下内容：传输方式、多入多出(Multiple-Input Multiple-Output，MIMO)方式、调制编码方式等级、时频资源位置和RV版本号。
本申请实施例中，将上行的CQI即上行CQI或下行的CQI即下行CQI统一描述为CQI，其中上行CQI是指基站通过测量得到的等效SINR值计算的CQI，下行CQI是指UE向基站反馈的CQI。
在计算CQI时，UE或基站根据检测后的SINR值通过SINR至互信息(Mutual Information，MI)的映射(SINR to MI mapping)的方式映射得到MI值，或根据信道容量通过容量到MI的映射的方式映射得到MI值，而MI值会和实际的调制方式相对应，比如正交相移键控的(Quad-Phase Shift Keyed，QPSK)调制对应的MI值的上限为2，16正交幅相调制(Quadrature Amplitude Modulation，QAM)对应的MI值的上限为4，64QAM对应的MI值的上限为6，256QAM对应的MI值的上限为8，因此，在SINR值或容量映射到MI过程中需要针对不同的调制方式分别计算对应的MI的值，而最后在计算最终的MI值时也需要对所有调制方式进行遍历得到最大的MI值，将最终的MI值得到CQI的值。以UE支持的调制方式包括：QPSK，16QAM，64QAM、256QAM为例，计算CQI的值的实现过程如图3所示：
S301、根据等效信道状态信息计算等效信噪比的值或容量的值。
根据等效信道状态信息Heq,i计算最小均方差(minimum mean-square error，MMSE)检测或球形译码(Sphere Decoder，SD)检测对应的等效信噪比的值或容量的值。
可选地，通过公式(1)计算等效信噪比的值，并通过公式(1)和公式(2)计算容量的值：

Ci,l＝log 2(1+γi,l)        公式(2)；
其中，i为样值点索引，i的取值小于子带或宽带中样值点的数量N，l为层数索引，l的取值可等于1或小于1。γi,l为样值点i层数l对应的等效信噪比，Ci,l为样值点i层数l对应的容量，I为单位矩阵。
这里，样值点数为子载波的个数，层数是指支持的秩(rank)的值，秩的值用于指示终端支持的最大MIMO的流数，即终端设备可以传输多少个数据流，其中，rank的秩可理解为传输层数。
S302、遍历所有的调制方式，根据等效信噪比的值或容量的值确定各调制方式对应的MI的值。
这里，MI的值为子带或宽带的MI的值。
在S302中，如图4所示，包括：
S3021、初始m为1；
S3022、计算第m个调制方式对应的MI的值；
在计算第m个调制方式对应的MI的值后，如果m的取值小于m的最大取值，则执行S3023，否则，认为遍历完所有的调制方式，计算得到所有调制方式对应的MI的值。
S3023、m的值加1。
m的取值加1，并继续执行S2023计算第m个调制方式对应的MI的值。
这里，m的取值范围基于终端设备支持的调制方式的数量确定，终端设备支持4个调制方式，则m的取值为1至4。
对于所有调制方式中的第m个调制方式通过图5所示的步骤S30221、S30222计算得到第m个调制方式对应的MI的值，其中，m的取值为1至4，m为1时，调制方式为QPSK，m为2时，调制方式为16QAM，m为3时，调制方式为64QAM，m为4时，调制方式为256QAM。
第m个调制方式对应的MI的值的计算如图5所示，包括以下步骤：
S30221、将等效SINR值或容量值映射至MI的值。
如公式(3)所示将等效SINR值映射至MI的值或如公式(4)所示，将容量的值映射至MI的值：

其中，表示第m个调制方式中样值点i层数l对应的MI。
S30222、将各样值点上的MI的值进行累加得到第m个调制方式对应的MI的值。
第m个调制方式对应的MI的值的计算如公式(5)所示：
S303、从所有的调制方式对应的MI的值中，选择最大的MI的值作为最终的MI的值。
最终的MI的值可表示为公式(6)：
S304、根据MI的值和MI至CQI映射得到对应的CQI的值。
在从等效SINR的值或容量的值到MI映射，样值点的MI累加过程中需要针对所有的调制方式进行映射，如UE最大支持64QAM，需要对3个调制方式进行映射，UE最大支持256QAM，则需要对4个调制方式进行映射，当UE支持1024QAM，需要对5个调制方式进行映射，复杂度随着调制方式的增加而线性增长。
下面，结合图1所示的通信系统的示意图，对本申请实施例提供的无线通信方法、装置、设备和存储介质的各实施例进行说明。
本申请实施例提供的无线通信方法，应用于通信设备，通信设备可为终端设备或网络设备，如图6所示，包括：
S601、通信设备根据参考信道信息，从终端设备支持的多个调制方式中选择第一调制方式集合。
通信设备从终端设备支持的多个调制方式中选择部分调制方式构成第一调制方式集合，第一调制方式集合中包括一个或多个调制方式。
在一示例中，终端设备支持的调制方式包括：QPSK、16QAM、64QAM、256QAM，通信设备从终端设备支持的调制方式中选择的第一调制方式集合包括以下调制方式：QPSK、16QAM、64QA M。
本申请实施例中，通信设备从终端设备支持的调制方式中选择第一调制方式集合的选择方式可支持以下一种或多种：
选择方式一、随机选择；
选择方式二、根据参考信道信息选择。

可选地，不同的传输层数对应的至少一个目标信噪比门限值不同。
不同的传输层数对应不同的至少一个信噪比门限值可理解为不同的传输层对应的至少一个信噪比是相互独立的。当CSI指示的传输层数不同，则第一设备确定的目标信噪比门限值不同。
以传输层数对应的信噪比门限值的数量为1为例，rank的值为1，对应的信噪比门限值为SINR1，rank的值为2，对应的信噪比门限值为SINR2，rank的值为3，对应的信噪比门限值为SINR3，rank的值为4，对应的信噪比门限值为SINR4；若CSI指示的传输层为1，则目标信噪比门限值为SINR1；若CSI指示的传输层为2，则目标信噪比门限值为SINR2；若CSI指示的传输层为3，则目标信噪比门限值为SINR3；若CSI指示的传输层为4，则目标信噪比门限值为SINR4。
可选的，传输层数越多，在对应的至少一个信噪比门限值中处于相同位置的信噪比门限值越大。这里信噪比门限值在所属的至少一个信噪比门限值中的位置基于该至少一个信噪比门限值中各信噪比门限值的大小确定。

此时，至少一个目标信噪比门限值所包括的目标信噪比门限值为第一目标信噪比门限值，基于第一目标信噪比门限值确定两个信噪比范围：小于第一目标信噪比门限值(第一信噪比范围)、大于或等于第一目标信噪比门限值(第二信噪比范围)，且第一信噪比范围对应第一候选调制方式集合，第二信噪比范围对应第二候选调制方式集合。
第一候选调制方式集合和第二候选调制方式集合所包括的调试方式的数量相同，且第二候选调制方式集合的最大调制阶数和最小调制阶数分别大于第一候选调制方式集合的最大调制阶数和最小调制阶数，

对于方式二

通信设备可遍历第一调制方式集合中所有的调制方式，根据等效信噪比的值或容量的值确定各调制方式对应的MI，并从所有的调制方式对应的MI的值中，选择最大的MI的值作为最终的MI的值，最终的MI的值对应的调制方式为目标调制方式。
本申请实施例中，最终的MI的值可表示为公式(6)：
其中，表示第l个传输层中第一调制方式集合中第m个调制方式对应的MI，在实际应用中，在信道包括多个传输层的情况下，各传输层对应的第一CQI独立计算，即各第l个传输层的对应的MI独立计算。在信道包括1个传输层的情况下，l的取值仅为1，或将l忽略。
本申请实施例提供的无线通信方法中，通信设备在映射MI的值时，仅遍历第一调制方式集合中的各调制方式，对于终端设备支持的调制方式中第一调制方式集合以外的调制方式，不需要确定该调制方式的MI的值，从而减少需要遍历的调制方式的数量，且从相对于图5所示的确定最终的MI的值的更小的选择范围中进行最终的MI的值的选择，从而提高CQI的计算效率，降低CQI的计算复杂度。

这里，可通过公式(4)将样值点的容量映射为第一调制方式下所述样值点的MI：
本申请实施例中，通信设备可根据等效信道状态信息Heq,i计算MMSE检测或SD检测对应的等效信噪比的值或容量。
在一些实施例中，S603基于所述目标调制方式对应的互信息生成第一信道质量指示，包括：将互信息至信道质量指示的映射中，所述目标调制方式的互信息的值对应的信道质量指示确定为所述第一信道质量指示。
在一些实施例中，通信设备还实施以下处理：以所述第一信道质量指示更新所述参考信道信息。
通信设备得到第一CQI后，可基于第一CQI对参考信道信息中的第二CQI进行更新，以基于当前的第一CQI计算下一个第一CQI。
在一些实施例中，通信设备还实施以下步骤：将所述第一信道质量指示发送至网络设备，使得所述网络设备基于所述第一信道质量指示调度频谱资源。
此时，通信设备为终端设备，所述第一CQI属于下行CQI，终端设备得到第一CQI后，将第一CQI上报给网络设备，网络设备根据所述终端设备上报的第一CQI的值为所述终端设备调度频域资源。
在一些实施例中，通信设备还实施以下步骤：基于所述第一信道质量指示调度频谱资源。
此时，所述第一CQI属于上行CQI，通信设备为网络设备，网络设备基于计算的第一CQI的值为终端设备调度频域资源。
在实际应用中，网络设备还可基于第一CQI的值为所述终端设备选择调制编码方式。
以通信设备为网络设备为例，网络设备进行SRS测量得到等效信噪比，并基于等效信噪比计算上行CQI的值，以基于计算的上行CQI的值为终端设备选择频域资源。
本申请实施例提供的无线通信方法，可应用于基站计算上行CQI的值的场景，也可以应用于终端设备计算下行CQI的值的场景，因此，本申请实施例提供的计算CQI的值的方式能够适用于多个不同的通信场景，能够减少各通信场景下计算CQI的复杂度。
下面，对本申请实施例提供的无线通信方法进行进一步说明。
本申请实施例提供的无线通信方法中，并不是对所有的调制方式都进行映射，而是根据信道的先验信息进行候选调制方式集合即候选调制方式集合的选择，如当信噪比较高时，针对高阶调制方式进行映射，当信噪比较低时，针对低阶调制方式进行映射，或根据UE历史上报的CQI信息进行一些适当的候选调制方式集合中的调制方式的数量的减少，从而降低实现复杂度。
本申请实施例提供的无线通信方法，如图8所示，
S801、从多个候选调制方式集合中选择第一调制方式集合。
其中，多个候选调制方式集合是由终端设备支持的调制方式所划分的。
S802、根据等效信道状态信息计算等效信噪比的值或容量的值。
S803、遍历第一调制方式集合中的调制方式，根据等效信噪比的值或容量的值确定第一调制方式集合中各调制方式对应的MI的值。
S804、从第一调制方式集合中的调制方式对应的MI的值中，选择最大的MI的值作为最终的MI的值。
S805、根据MI的值和MI至CQI表格得到对应的CQI的值。
图8所示的无线通信方法的可实施于终端设备，也可实施于基站。
如图8所示的无线通信方法在图3所示的无线通信方法计算CQI的值之前，增加S801，以进行第一调制方式集合的选择。在S801中，可根据信道状态信息或历史上报的CQI信息进行候选调制方式的选择过程。在根据等效信噪比的值和容量的值确定所有的随机方式对应的MI的值之前，针对S302和S303，在图8所示的无线通信方法中，只需要对候选调制方式集合中的调制方式进行遍历，并不需要对所有的调制方式进行遍历。因此降低了CQI计算的复杂度。
本申请实施例提供的无线通信方法能够实施且不限于以下实施例：
实施例一、根据信道状态信息选择调制方式的候选调制方式集合
将调制方式分成两个集合组。以支持256QAM调制的UE为例，将候选调制方式分为两个集合，低调制方式集合{QPSK，16QAM，64QAM}，高调制方式集合{16QAM，64QAM，256QAM}。
如图9所示，终端设备选择候选调制方式集合的步骤包括：
S901、终端设备计算当前信道状态信息对应的等效SINR的值。
这里，可通过公式(7)计算当前信道状态信息对应的等效SINR的值：
其中，RSRP表示信号的功率；Npwr表征干扰加噪声的功率。
S902、终端设备基于等效SINR的值确定第一调制方式集合。
若UE上报的rank＝1，则当SINR＞SINR1，选择的第一调制方式集合为高阶调制方式集合，否则，选择的第一调制方式集合为低阶调制方式集合；若UE上报的rank＝2，则当SINR＞SINR2，选择的第一调制方式集合为高阶调制方式集合，否则，选择的第一调制方式集合为低阶调制方式集合；若UE上报的rank＝3，则当SINR＞SINR3，选择的第一调制方式集合为高阶调制方式集合，否则，选择的第一调制方式集合为低阶调制方式集合；若UE上报的rank＝4，则当SINR＞SINR4，选择的第一调制方式集合为高阶调制方式集合，否则，选择的第一调制方式集合为低阶调制方式集合。
在实施例一中，利用信道的先验信息如信噪比可以预先判断当前信道质量的范围，当信道质量较好时，选择高阶调制方式候选调制方式集合，当信道质量较差时，选择低阶调制方式候选调制方式集合。
实施例二、根据历史上报的CQI信息来选择调制方式的候选调制方式集合；
根据CQI等级表格我们可以得到实际的调制方式等级，假设两次上报时信道的变化在10dB以内，这样两次上报的CQI值不会超过5个等级(该假设在周期上报时可以认为基本上是满足的)例如当历史上报的CQI值<CQI6,则可以选择低阶的调制方式候选调制方式集合，当历史上报的CQI值>CQI10时，则选择高阶的调制方式候选调制方式集合，当历史上报的CQI值位于[6,10]之间时，则选择和上一次上报相同的调制方式候选调制方式集合。CQI的值与CQI等级之间的关系可如表示1所示。
表1、CQI的值与CQI等级示例

在实施例二中，利用历史CQI上报值和信道变化的特点预先判断当前信道可能采用的调制方式，选择合适的候选调制方式集合，在不损失性能的基础上降低实现复杂度。
在上述实施例中，以从2个候选调制方式集合中选择第一调制方式集合即目标调制方式集合为例对本申请实施例提供的无线通信方法进行说明，可以扩展至从3或更多个候选调制方式集合中选择第一调制方式集合，此时只需要增加更多的门限即可灵活实现。
上述实施例应用于终端设备侧，在实际应用中，本申请实施例提供的无线通信方法也可应用于基站。
本申请实施例提供的无线通信方法，利用信道状态信息或历史上报CQI的先验信息对本次上报的CQI的值进行预测，在实现过程中并不需要对所有的调制方式进行遍历，仅需要对候选调制方式集合中的调制方式进行遍历，同时利用了信道的一些先验信息，在不损失性能的基础上能有效降低实现复杂度。如对于支持256QAM调制的UE来说，采用现有技术，需要进行4次遍历，当采用本技术方案，可仅需要3次遍历，复杂度降低25％。
