本申请实施例中，在第二通信设备具备支持1024QAM能力的情况下，第一通信设备向第二通信设备发送第一指示信息，而第一指示信息用于指示第二通信设备进行数据传输使用的MCS表格，第一通信设备根据MCS表格确定MCS等级后，通过第三指示信息将第二通信设备接收或发送的信道对应的MCS等级通知给第二通信设备，以指示第二通信设备根据该MCS等级确定其接收或发送的信道使用的调制方式和码率。
本申请实施例所提供MCS表格至少包括调制阶数为10的调制方式对应的MCS等级，那么第三指示信息确定的MCS等级也就有可能是调制阶数为10的调制方式对应的MCS等级，第二通信设备具备支持1024QAM能力，第二通信设备也就能够为其调度的信道使用调制阶数为10对应的调制方式和码率，使得通信系统能够支持更高阶调制，确保通信系统在高信噪比通信场景下能够具有较高的数据吞吐量，提升通信系统的传输效率。
本申请实施例中，包括调制阶数为10的调制方式对应的MCS等级的MCS表格可以是基于CQI表格来设计。可选地，所述CQI表格包括1024QAM对应的CQI等级，且所述CQI表格满足如下至少一项条件：
包括第一CQI表格中256QAM对应的CQI等级，所述第一CQI表格为包括256QAM对应的CQI等级的CQI表格(即如上所示表格5)；

在所述码率出现小数的情况下，所述码率通过四舍五入取整的方式确定；
在所述码率出现小数的情况下，所述码率保留至一位小数。
需要说明的是，为更好地与上述CQI表格1～3区分，本申请实施例的以下描述中将包括1024QAM对应的CQI等级的CQI表格称之为第一目标CQI表格，所述第一目标CQI表格也就满足上述至少一项条件。
其中，所述第一目标CQI表格包括第一CQI表格(也即表5，CQI表格2)中256QAM对应的CQI等级，也就是说，所述第一目标CQI表格可以是在上述CQI表格2的基础上来进行设计。
本申请实施例中，所述CQI表格中包括与1024QAM调制方式对应的至少两种CQI等级。也就是说，第一目标CQI表格中包括与1024QAM调制方式对应的至少两种CQI等级，例如可以是包括第一CQI等级和第二CQI等级，或者在此基础上还可以包括第三CQI等级和第四CQI等级。
可选地，在一种实施方式中，第一目标CQI表格中包括与1024QAM调制方式对应的第一CQI等级和第二CQI等级，所述第一CQI等级对应的码率与所述第二CQI等级对应的码率不同，所述第一CQI等级对应的频谱效率与所述第二CQI等级对应的频谱效率不同。
也就是说，第一目标CQI表格中包括与1024QAM调制方式对应的第一CQI等级和第二CQI等级。另外需要说明的是，第一目标CQI表格是在上述CQI表格2的基础上来进行设计，第一目标CQI表格中保留CQI表格2中256QAM对应的CQI等级，而需要新增与1024QAM调制方式对应的第一CQI等级和第二CQI等级，则可以是相应删减CQI表格2中的两个CQI等级；可 选地，可以是按照QPSK、16QAM、64QAM的预设删减顺序进行删减，例如优先删减QPSK对应的CQI等级，而后删减16QAM及64QAM对应的CQI等级。当然，可以是遵循其他的规则来对CQI表格2中的CQI等级进行选择性删减。在本申请实施例一种可选的实施方式中，将CQI表格2中CQI index为5对应的CQI等级和CQI index为7对应的CQI等级删减，并新增与1024QAM调制方式对应的第一CQI等级和第二CQI等级。
其中，第一目标CQI表格中，所述第一CQI等级与第二CQI等级对应的码率和频谱效率可以是基于上述条件中的至少一项来确定。例如，第一目标CQI表格中各CQI等级对应的频谱效率等间隔，则基于CQI表格2中已确定的各CQI等级之间的频谱效率，也就能够确定第一CQI等级和第二CQI等级分别对应的频谱效率；第一CQI等级和第二CQI对应的频谱效率通过四舍五入的方式保留至四位小数。又如，第一目标CQI表格中各CQI等级对应的码率等间隔，则基于CQI表格2中已确定的各CQI等级之间的码率，也就能够确定第一CQI等级和第二CQI等级分别对应的码率。或者，第一目标CQI表格中的码率还可以满足于：在码率出现小数的情况下，所述码率可以是通过向上取整或向下取整或四舍五入取整的方式确定，或者所述码率保留至一位小数。例如，所述第一CQI等级对应的码率可能是整数，也可能是保留有一位小数，或者所述第一CQI等级对应的码率也可以是对应有多个取值，等。
可选地，所述第一CQI等级对应的码率和频谱效率可以是基于上述条件来确定，例如所述第一CQI等级对应的码率为853，对应的频谱效率为8.3321。
可选地，所述第二CQI等级对应的码率和频谱效率也可以是基于上述条件来确定，例如所述第二CQI等级对应的码率为948，对应的频谱效率为9.2578。
这样，也就能够得到第一目标CQI表格为如下表7所示的CQI表格4：
表7.CQI表格4

在上述CQI表格4中，与1024QAM调制方式对应的第一CQI等级和第二CQI等级分别是对应于CQI index 14和CQI index 15。这样，第一通信设备发送给第二通信设备的第二指示信息，除了能够指示上述CQI表格1～3之外，还可以是指示CQI表格4，进而第二通信设备进行信道质量反馈使用的CQI表格也就可以包括1024QAM调制方式对应的CQI等级，进而以方便通信系统更高阶的调制。
本申请实施例中，CQI表格中包括与1024QAM调制方式对应的至少两种CQI等级，在上述CQI表格4中包括第一CQI等级和第二CQI等级的基础上，所述CQI表格中还包括与1024QAM调制方式对应的第三CQI等级和第四CQI等级，所述第三CQI等级和所述第四CQI等级基于所述第一CQI等级和所述第二CQI等级获得。
也就是说，在上述CQI表格4的基础上，还可以进一步增加与1024QAM调制方式对应的第三CQI等级和第四CQI等级，同时CQI表格4中的第一CQI等级和第二CQI等级保留。为更好地说明本实施方式，将包括第一CQI等级、第二CQI等级、第三CQI等级和第四CQI等级的CQI表格定义为第二目标CQI表格，该第二目标CQI表格同样满足如下至少一项条件：

可以理解地，第二目标CQI表格为在上述CQI表格4基础上进行设计，新增与1024QAM调制方式对应的第三CQI等级和第四CQI等级，则可以是相应删减CQI表格4中的两个CQI等级，但需要同时保留1024QAM和256QAM调制方式对应的CQI等级。其中，第三CQI等级和第四CQI等级对应的码率和频谱效率可以是基于上述条件中的至少一项来确定。例如，第二目标CQI表格中各CQI等级对应的频谱效率等间隔，则基于上述CQI表格4中已确定的各CQI等级的频谱效率，也就能够确定第三CQI等级和第四CQI等级对应的频谱效率；以及，第三CQI等级和第四CQI等级对应的频谱效率通过四舍五入的方式保留至四位小数。另外，第三CQI等级和第四CQI等级与其他CQI等级之间的码率等间隔，当码率出现小数的情况下，所述码率可以是通过向上取整或向下取整或四舍五入取整的方式确定，或者所述码率保留至一位小数。例如，第三CQI等级对应的码率可以是对应有多个取值，第四CQI等级对应的码率也可以是对应有多个取值。
可选地，第三CQI等级可以是通过第一CQI等级和第二CQI等级插值获得，例如第一CQI等级、第二CQI等级和第三CQI等级对应的频谱效率等间隔，第一CQI等级和第二CQI等级的频谱效率已知，这样也就能够确定出第三CQI等级对应的频谱效率。第四CQI等级也可以是通过第一CQI等级和第二CQI等级插值获得。
其中，所述第三CQI等级对应的码率为如下任意一者：805、806、805.5，所述第三CQI等级对应的频谱效率为如下任意一者：7.8613、7.8711、7.8662。

在上述MCS表格8～11中，与调制阶数为10的调制方式对应的MCS等级分别为MCS Index 19～26以及MCS Index 31。这样，第一通信设备也就能够指示第二通信设备进行数据传输所使用的MCS表格也就包括MCS表格1～11，进一步提高了MCS表格的数量，提高了第二通信设备对于信道接收和发送所使用的MCS等级的选择性和灵活性，也有效提高了通信设备对于信道接收或发送的调制方式，以提升通信系统在高信噪比场景下的数据吞吐量。
本申请实施例中，所述MCS表格适用于如下至少一项：
由小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)或配置调度RNTI(Configured Scheduling RNTI，CS-RNTI)进行循 环冗余校验(Cyclic Redundancy Check，CRC)加扰的第一下行控制信息格式的PDCCH调度的PDSCH；
由C-RNTI或CS-RNTI进行CRC加扰的第二DCI格式的PDCCH调度的PDSCH；
由C-RNTI或CS-RNTI进行CRC加扰的第三DCI格式调度的物理上行共享信道PUSCH或由RRC信令配置的免授权PUSCH。
也就是说，上述包括调制阶数为10的调制方式对应的MCS等级的MCS表格，也即上述MCS表格4～11可以是适用于由C-RNTI或CS-RNTI进行CRC加扰的DCI格式1_1的PDCCH调度的PDSCH；和/或适用于由C-RNTI或CS-RNTI进行CRC加扰的DCI格式1_2的PDCCH调度的PDSCH；和/或适用于由C-RNTI或CS-RNTI进行CRC加扰的DCI格式0_1或DCI格式0_2所调度的PUSCH，或者适用于RRC信令配置的免授权PUSCH。
本申请实施例中，在所述步骤201之前，还可以包括：
接收所述第二通信设备上报的第四指示信息，所述第四指示信息用于指示所述第二通信设备是否具备支持1024 QAM能力。
也就是说，第一通信设备先接收第二通信设备上报的第四指示信息，若第四指示信息指示所述第二通信设备具备支持1024 QAM的能力，则第一通信设备再向第二通信设备发送第一指示信息、第二指示信息和第三指示信息，也就是指示第二通信设备进行数据传输使用的MCS表格和进行CQI反馈使用的CQI表格，以及将为第二通信设备接收和发送的信道对应的MCS等级通知给第二通信设备。第二通信设备具备支持1024QAM能力，第二通信设备也就能够为其调度的信道使用调制阶数为10对应的调制方式和码率，使得通信系统能够支持更高阶调制，确保通信系统在高信噪比通信场景下能够具有较高的数据吞吐量，提升通信系统的传输效率。
可选地，所述第四指示信息通过如下粒度任意一项进行上报：
每个频段；
频段组合；
载波特征集合(Feature Set Per Component-carrier，FSPC)。
例如，第二通信设备可以是通过每个频段(per band)和/或几个频段组合(band combination)来上报第四指示信息，或者也可以是通过FSPC来上报第四指示信息，进而以将第二通信设备是否具备支持1024 QAM能力通知给第一通信设备，使得第一通信设备能够确定为第二通信设备调度的信道对应的MCS等级，有利于第一通信设备和第二通信设备之间的通信顺畅。
