具体实施方式
此处所描述的具体实施例仅仅用以解释本申请。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本申请的说明，其本身没有特有的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
图1是本申请实施例提供的一种调制编码策略的配置方法的流程图，本实施例可适用于无线通信中支持高阶调制方式的情况，该方法可以由本申请实施例中的调制编码策略的配置装置来执行，该装置可以通过软件和/或硬件的方式实现，并一般可以集成在基站中，本申请实施例的方法包括如下步骤：
步骤110、确定第一调制编码策略集合。
第一调制编码策略集合是由调制编码策略MCS组成的集合，第一调制编码策略集合中包括至少一个调制编码策略，在一个可选的实施方式中，第一MCS 集合可以是包含多个MCS的表格。
在本申请实施例中，基站可以根据网络状况、终端数量、传输块尺寸、调制方式等网络属性信息确定出调制编码策略，并将确定出的调制编码策略组成第一调制编码策略集合，第一调制编码策略集合中不同的网络属性取值可以对应不同的调制编码策略。
步骤120、基于所述第一调制编码策略集合为目标数据配置调制编码策略。
目标数据可以是待发送的业务数据或者控制信令。
可以根据确定出的第一调制编码策略MCS集合，选择适合的调制编码策略配置于发送目标数据。
本申请实施例的技术方案，通过确定第一调制编码策略集合，通过第一调制编码策略集合对目标数据配置调制编码策略，实现了对高阶调制方式的支持，可提高窄带物联网的通信性能，增强通信网络质量。
在上述申请实施例的基础上，所述确定第一调制编码策略集合，包括：根据资源单元的数量确定第一调制编码策略集合，其中，所述第一调制编码策略集合至少包括以下至少之一：调制编码策略索引与调制方式的对应关系和调制编码策略索引与传输块尺寸索引的对应关系。
资源单元(Resource Unit，RU)可以是基站为终端(User Equipment，UE)配置的用于传输数据的无线资源，可以根据资源单元的数量多少确定第一调制编码策略集合，当资源单元的数量属于不同的数量集合时，其对应的第一调制编码策略MCS集合可以不同。可以按照资源单元的数量在预先设置的调制编码策略集合中查找对应的第一调制编码策略集合，其中，第一调制编码策略集合中包括调制编码策略索引与调制方式的对应关系以及调制编码策略索引与传输块尺寸索引的对应关系，调制编码策略索引可以标识不同的调制编码策略，每条调制编码策略中可以包括调制方式和传输块尺寸。
在上述申请实施例的基础上，当配置的资源单元的数量属于第一数量集合或第二数量集合时，所述第一调制编码策略集合包含一个调制编码策略子集，所述调制编码策略子集包含预设数量的调制编码策略，所述预设数量的调制编码策略中每相邻两个调制编码策略对应的传输块尺寸(Transport Block Size，TBS)索引之差为K，K大于或等于2，其中，所述第一数量集合与所述第二数量集合不同，所述预设数量的取值对应于所述第一数量集合或所述第二数量集合。
第一数量集合和第二数量集合可以是资源单元RU数量的数值集合，第一数量集合包含的数值可以与第二数量集合包含的数值不同，例如，第一数量集合包括1、2、3、4和5，而第二数量集合可以包括6。其中，调制编码策略子集 可以由一个或者多个调制编码策略组成，调制编码策略子集可以是第一调制编码策略集合的一部分或者全部。
在本申请实施例中，当资源单元的数量属于第一数量集合或者第二数量集合时，第一数量集合对应的第一MCS集合与第二数量集合对应的第一MCS集合是不同的。
在一个示例性的实施方式中，当为UE配置的资源单元RU数量属于第一数量集合时，所述MCS集合包含一个MCS子集，所述MCS子集包含7个MCS，所述7个MCS中每相邻两个MCS对应的TBS索引之差为2。本实施例中，在为UE配置的资源单元RU数量属于第一数量集合的情况下，TBS的数量大于MCS数量，所以TBS不能一一对应MCS，需要选择一定数量的TBS与MCS进行对应。考虑到16QAM主要用于提高数据速率，适合信道条件好的场景，低重复或无重复次数。所以，高信噪比(Signal-to-Noise Ratio，SNR)区间和较大的TBS部署应该是16QAM MCS表格设计的主要目标。那么，在较高的MCS区间，设置连续的大TBS，即每相邻两个MCS对应的TBS索引之差为1，例如TBS 13，14，15，…，21，这样可以保证高SNR下的数据传输效率；在低MCS区间，设置间隔的小TBS，即每相邻两个MCS对应的TBS索引之差为2，例如TBS 0，2，4，6，…，12。较小的TBS能够在信道恶化时保证传输的可靠性。
本实施例中，调制方式与调制阶数为等价关系，16QAM的调制阶数为4，QPSK的调制阶数为2。
本申请实施例中第一数量集合至少包括1，2，3，4和5，那么在本申请实施例中，当为UE配置的资源单元RU数量大于或等于1且小于或等于5时，TBS的范围为大于或等于0且小于或等于21，MCS的范围为大于或等于0且小于或等于15，那么MCS和TBS的对应关系为：MCS 0至6对应TBS 0、2、4、6、8、10、12，此外，MCS 7至15对应TBS 13～21。表一给出了一个具体示例。

相应的，本实施例中，当为UE配置的资源单元RU数量为6时，TBS的范围为大于或等于0且小于或等于21，MCS的范围为大于或等于0且小于或等于15，那么MCS和TBS的对应关系为：MCS 0至4对应TBS 0、2、4、6、TBS 8，此外，MCS 5至15对应TBS 9至19。表二给出了一个具体示例。

在上述申请实施例的基础上，所述根据资源单元的数量确定第一调制编码 策略集合，包括：
当配置的所述资源单元的数量属于第三数量集合时，所述第一调制编码策略集合中的调制编码策略索引分别从0到15依次对应传输块尺寸索引从0到15。
在本申请实施例中，第三数量集合对应的第一调制编码策略集合中包括16条调制编码策略，其中，调制编码策略索引与传输块尺寸索引存在对应关系，调制编码策略索引按照从0-15的顺序与传输块尺寸索引从0到15对应，调制编码策略索引0对应传输块尺寸索引0，调制编码策略索引1对应传输块尺寸索引1，第三集合对应的第一调制编码策略集合中的调制编码策略索引与传输块尺寸索引可以此类推。当基站确定为终端配置的资源单元的数量属于第三数量集合时，可以选择具有调制编码策略索引分别从0到15依次对应传输块尺寸索引从0到15关系的调制编码策略集合作为对应的第一调制编码策略集合。
在一个示例性的实施方式中，第三数量集合可以至少包括8。当为UE配置的资源单元RU的数量为8时，TBS的范围为大于或等于0且小于或等于15，MCS的范围也是大于或等于0且小于或等于15，那么MCS和TBS的对应关系为：MCS 0至15依次对应TBS 0至15，表三给出了一个具体示例。

最大索引值可以是传输块尺寸索引的最大数值。
在本申请实施例中，第四数量集合对应的第一调制编码策略集合中传输块尺寸的索引的最大值为13，并且存在至少一对调制编码策略，具有相同的传输块尺寸索引，但是对应的调制方式不同。当确定配置的资源单元的数量属于第四数量集合时，可以确定第四数量集合下的第一调制编码策略集合，该调制编码策略集合中包括的传输块尺寸索引的最大索引值为13，并且存在至少一对调制编码策略对应的传输块尺寸相同且调制方式不同。
示例性的，第四数量集合可以至少包括10，当为UE配置的资源单元RU数量为10时，TBS的范围为大于或等于0且小于或等于13，MCS的范围为大于或等于0且小于或等于15，MCS数量大于TBS数量，因此至少可以设置一对MCS对应相同的TBS N，例如N＝11，且这对MCS具有不同的调制方式，这样设置的好处是，针对这个TBS N，可以得到一个高阶调制和低码率的MCS，以及一个低阶调制和高码率的MCS，这两个MCS适用于不同的信道状态和资源分配情况，有利于MCS部署，提高传输性能。
一个具体示例中，假定所述TBS N为TBS 11，则MCS和TBS的对应关系包括：MCS 0至11对应TBS 0至11，MCS 12至14对应TBS 11至13，如表四所示。

在上述申请实施例的基础上，所述配置的调制编码策略的调制方式为16正交幅度调制时，所述目标数据对应的物理共享信道的重复次数小于或等于2。
在本申请实施例中，由于16QAM比QPSK调制阶数高，所以需求的信道条件更高，在一个给定的信道条件下，物理共享信道可能需要重复传输才能保证16QAM调制正确接收，而当物理共享信道的重复次数增大时，16QAM的数据速率会降低，直到比QPSK的数据速率更低。针对NB-IoT网络，表七对比了16QAM和QPSK的峰值速率，从表七可以发现，16QAM调制在重复次数为2时的峰值数据速率仍然大于QPSK的峰值速率，但是16QAM在4次重复传输下的峰值数据速率小于QPSK的峰值速率。因此，当为UE配置的MCS为16QAM调制时，为了提高传输效率，可以限制物理共享信道的重复次数小于或等于2。

在上述申请实施例的基础上，当高层配置参数指示数据传输支持高阶调制时，下行控制信息中子载波指示域的最高位比特作为调制编码策略指示信息的一个比特，所述高阶调制的调制阶数大于或等于4。
高层配置参数可以指示数据传输是否支持高阶调制，例如是否支持16QAM调制；子载波指示域可以是下行控制信息(Downlink Control Channel，DCI)中指示子载波数量和/或位置的信息域，可以包括一个或者多个比特位。
当通过高层配置参数指示数据传输可以支持调制阶数大于或等于4的高阶调制时，可以将下行控制信息中子载波指示域的最高位比特作为调制编码策略指示信息的一个比特。在下行控制信息中，所述子载波指示域的最高位比特与MCS指示信息域的比特一起用于指示MCS信息，即指示为数据配置的MCS索引。
在本申请实施例中，调制编码策略指示信息用于指示MCS集合中的一个MCS，基站通过下行控制信息中的MCS指示信息向UE指示使用哪个MCS。 在Release-16NB-IoT技术中，MCS指示信息域包含4个比特，而当高层配置参数指示高阶调制被配置时，MCS的配置范围可能增大，由此MCS指示信息可能需要增加到5个比特。考虑到在Release-16NB-IoT技术中，下行控制信息中的子载波指示域包含6个比特，而在15kHz子载波间隔的情况下，所述子载波指示域中的最高位比特是保留状态的，即没有利用起来。所以可以将下行控制信息中子载波指示域的最高位比特作为MCS指示信息的一个比特，这样MCS指示信息就变为5个比特，并且没有额外增加下行控制信息的开销。
在上述申请实施例的基础上，还包括：当高层配置参数指示数据传输支持高阶调制时，下行控制信息中子载波指示域指示子载波信息和调制编码策略集合。
所述子载波信息包含子载波的数量和/或位置序号。
在本申请实施例中，当所述子载波指示域的值小于或等于18时，子载波指示域指示的所述调制编码策略集合包含MCS索引0至K，K大于1。针对MCS0至K，由下行控制信息中的MCS指示域指示配置其中一个MCS。
当所述子载波指示域的值大于或等于12且小于或等于18时，子载波指示域指示的所述调制编码策略集合包含MCS索引0至K，K大于1。
本实施例中，当所述子载波指示域的值大于或等于19时，子载波指示域指示的所述调制编码策略集合包含MCS索引K+1至L-1，K大于1，L为所述第一调制编码策略集合包含的MCS数量，即所述第一调制编码策略集合中关联了调制方式的MCS数量，例如，如果所述第一调制编码策略集合中有MCS索引0至21关联了调制方式，则L＝22。
当所述子载波指示域的值大于或等于19且小于或等于25时，子载波指示域指示的所述调制编码策略集合包含MCS索引K+1至L-1。针对MCS K+1至L-1，由下行控制信息中的MCS指示域指示配置其中一个MCS。
在一个具体示例中，所述子载波指示域的值为j，当0≤j≤18时，所述调制编码策略集合包含MCS 0至K。当19≤j≤25时，所述调制编码策略集合包含MCS K+1至L-1。子载波指示域的值对应的信息如表八所示，其中I sc为子载波指示域的值，n sc为子载波索引，I MCS为MCS索引。

在上述申请实施例的基础上，所述第一调制编码策略集合包括的最大调制方式为16正交振幅调制16QAM，且所述第一调制编码策略集合包括以下至少两种：调制编码策略索引与目标码率的对应关系，调制编码策略索引与调制方 法的对应关系和调制编码策略索引与频谱效率的对应关系。
在本申请实施例中，第一调制编码策略集合中包含的最大阶数的调制方式可以为16正交振幅调制。并且第一调制编码策略集合中可以包括调制编码策略索引与目标码率的对应关系以及调制编码策略索引与调制方法的对应关系和调制编码策略索引与频谱效率的对应关系，第一调制边编码策略集合中可以包括调制编码策略索引、调制目标码率和频率利用利率等参数。
在上述申请实施例的基础上，所述述第一调制编码策略集合中最大调制编码策略索引对应的目标码率为658。
在本申请实施例中，所述第一MCS集合为4位MCS表格，包含16个MCS。因为MCS数量有限，所以16QAM关联的MCS支持的最大目标码率只达到658，这个目标码率较低，不能支持更高的数据速率需求。但是，4位MCS指示信息的开销较少，有利于下行控制信息的正确译码。
在上述申请实施例的基础上，所述第一调制编码策略集合中相邻的两个调制编码策略索引对应的频谱效率之差大于或等于0.05。
在第一调制编码策略集合中不存在频谱效率之差小于0.05的两个MCS，也就是说不存在频谱效率相近的两个MCS，其中，频谱效率差值小于0.05用于表示两个MCS的频谱效率相同或十分接近。因为4比特位的信息量有限，没有多余的信息来对应相同或相近的频谱效率，4比特MCS集合应该覆盖更多不同的频谱效率的MCS，这样有利于不同信道状态下的MCS分配。在一个示例性的实施方式中，第一调制编码策略集合可以如表十所示。

在上述申请实施例的基础上，第一调制编码策略集合中，对应16正交振幅调制的调制编码策略索引对应的目标码率的最大值为948。
第一MCS集合可以为5比特位的MCS表格，比4比特位的MCS表格包含更多的MCS，因此，5比特位的MCS表格具有足够的MCS数量，所以MCS对应的最大目标码率支持到948。由此，5比特位MCS表格可以支持更高的数据速率需求。第一MCS集合可以包含用于重传的MCS，即MCS只对应调制方式，而不对应调制目标码率和频谱效率。
在一个示例性的实施方式中，第一MCS集合如表十一所示。其中，当pi/2二进制相移键控(Binary Phase Shift Keying，BPSK)调制被使能时，q＝1；否则，q＝2。MCS 29、30、31为用于重传的MCS，表十一中用于重传的三个MCS也可以定义为MCS 23至31中的任意三个MCS索引。

图2是本申请实施例提供的一种功率的配置方法的流程图，本实施例可适用于无线通信中支持高阶调制方式的情况，该方法可以由本申请实施例中的功率的配置装置来执行，该装置可以通过软件和/或硬件的方式实现，并一般可以集成在基站中，本申请实施例的方法包括如下步骤：
步骤210、根据对应物理上行共享信道配置的调制编码策略中的调制方式确定所述物理上行共享信道的功率偏移参数。
在本申请实施例中，可以获取为物理上行共享信道配置的调制编码策略，可以根据调制编码策略中的调制方式确定对应的物理上行共享信道配置的功率偏移参数，发送端可以根据功率偏移参数对上行功率进行调整，以提高上行数据传输的性能。
步骤220、根据所述功率偏移参数为所述物理上行共享信道配置发送功率。
可以根据功率偏移参数为物理上行共享信道的功率进行补偿，可以将补偿后的功率作为为物理上行共享信道配置的发送功率。
本申请实施例，通过物理上行共享信道对应的调制方式确定出功率偏移参数，通过功率偏移参数为物理上行共享信道确定发送功率，以提高上行数据传输的性能。
在上述申请实施例的基础上，所述调制方式为低阶调制时，所述功率偏移参数为0，其中，所述低阶调制的调制阶数小于或等于2。
在上述申请实施例的基础上，所述调制方式为高阶调制时，所述功率偏移参数为第一功率偏移，其中，所述高阶阶调制的调制阶数大于或等于4。
在上述申请实施例的基础上，所述第一功率偏移由高层参数指示和/或下行控制信息指示。
基站利用高层参数和/或下行控制信息指示所述第一功率偏移的值；终端接收所述高层参数和/或下行控制信息，确定所述第一功率偏移的值。
在上述申请实施例的基础上，假定所述物理上行共享信道的第一发送功率为P，所述功率偏移参数为δ，则所述物理上行共享信道的发送功率等于P+δ。其中，所述第一发送功率为Release-16版本NB-IoT中的物理上行共享信道的发送功率。
在本申请实施例中，当基站对高阶调制方法进行支持时，需要更高的信噪比来保证正确接收，因此，利用功率偏移参数调节物理上行共享信道的发送功 率，针对高阶调制进行功率调整。本实施例利用功率偏移参数调节物理上行共享信道的发送功率，示例性的，针对16QAM调制进行功率调整，窄带物理上行共享信道(Narrowband PUSCH，NPUSCH)的发送功率由如下公式确定：
Figure PCTCN2021123336-appb-000009
其中，δ为所述功率偏移参数，对于QPSK调制，δ＝0；对于16QAM调制，δ＝ offset。δ offset为所述第一功率偏移，δ offset的值由高层参数指示或者由下行控制信息指示。除δ之外，其他参数都为Release-16版本协议中定义的参数。
P CMAX,c(i)为UE在服务小区c内时隙i上的发送功率，M NPUSCHc,(i)的值与发送带宽有关，对于3.75kHz子载波间隔，该值为1/4，对于15kHz子载波间隔，该值为{1,3,6,12}；
P O_NPUSCHc,(j)表示为：
P O_NPUSCHc,(j)＝P O_NOMINAL_NPUSCH,c(j)+P O_UE_NPUSCH,c(j)。
对于动态调度NPUSCH，j＝1；对于随机接入NPUSCH，j＝2。
j＝1时，等式右侧两项参数由高层参数给出；j＝2时，P O_UE_NPUSCH,c(2)＝0，P O_NORMINAL_NPUSCH,c(2)＝P O_PRE+Δ PREAMBLE_Msg3。α c(j)取值为：j＝2时，α c(j)＝1，j＝1时，NPUSCH格式2情况下α c(j)＝1，NPUSCH格式1情况下α c(j)由高层参数通知。PL c为UE估计的下行路损。
图3是本申请实施例提供的一种信道质量的上报方法的流程图，本实施例可适用于无线通信中支持高阶调制方式的情况，该方法可以由本申请实施例中的信道质量的上报装置来执行，该装置可以通过软件和/或硬件的方式实现，并一般可以集成在基站中，本申请实施例的方法包括如下步骤：
步骤310、确定信道质量指示集合，所述信道质量指示集合包括信道质量指示与信道质量参数的关联关系，其中，所述信道质量参数包括以下至少一种：调制方式、目标码率、频谱效率、调制编码策略索引、传输块尺寸索引以及重复次数，所述信道质量指示集合包括的最大的调制方式为16正交振幅调制。
信道质量指示(Channel quality indicator，CQI)集合可以由一个或多个CQI组成，每个CQI关联信道质量参数，所述信道质量参数至少包括以下之一：调制方式、目标码率、频谱效率、调制编码策略索引、传输块尺寸索引以及重复次数等信息。所述CQI集合可以是一个CQI表格。
步骤320、基于所述信道质量指示集合上报信道质量。
终端可以向基站上传信道质量指示实现信道质量的上报。
本实施例中，所述CQI集合为一个4比特的CQI表格，其中M个CQI索引用于对应MCS的目标码率或频谱效率，M小于或等于16。但是，MCS的数量大于或等于M，所以，需要从中选择M个MCS，将它们的目标码率或频谱效率与所述M个CQI索引一一对应。
在上述申请实施例的基础上，所述信道质量指示集合包括N个连续的信道质量指示索引，所述N个连续的信道质量指示索引依次对应N个连续的调制编码策略索引分别关联的目标码率或频谱效率，N大于或等于6。
例如，CQI索引1至6对应MCS索引0至5的目标码率或频谱效率，假设MCS 0至5的频谱效率分别为0.1、0.2、0.3、0.4、0.5、0.6，则CQI 1至6分别对应频谱效率0.1、0.2、0.3、0.4、0.5、0.6。
在上述申请实施例的基础上，所述信道质量指示集合中16正交振幅调制对应的最大目标码率为948或658。
所述CQI集合中16QAM对应的最大目标码率与16QAM MCS的最大目标码率相同，在16QAM MCS最大目标码率为948的情况下，所述CQI集合中16QAM对应的最大目标码率为948，在16QAM MCS最大目标码率为658的情况下，所述CQI集合中16QAM对应的最大目标码率为658。
在一个示例性的实施方式中，在所述CQI集合中，16QAM CQI对应的最大码率为658。16QAM传输的最大码率只支持到658，说明对数据速率要求不高，那么在高CQI索引区间，可以将CQI对应间隔的MCS索引关联的目标码率或频谱效率，较粗略的反应信道状态以节省有限的CQI信息，CQI 13、14、15对应MCS 11、13、15关联的目标码率或频谱效率。在较低的CQI区间，将CQI对应连续的MCS关联的目标码率或频谱效率，详细地反应信道状态，以保证数据传输的可靠性，CQI 2至12对应MCS 0至10关联的目标码率或频谱效率。
例如基于表十示出第一MCS表格，CQI 2至12依次对应其中MCS 0至10关联的目标码率或频谱效率，CQI 13至15依次对应其中MCS 11，13，15关联的目标码率或频谱效率。一个CQI表格可以如表十三所示。

在第一CQI集合中，CQI 10至15对应MCS 17至22所关联的目标码率和频谱效率。
在又一个具体示例中，所述第一CQI集合中，16QAM CQI对应的最大码率为948。16QAM传输的最大码率达到948，说明对数据速率要求高，那么在高CQI索引区间，可以将CQI对应连续的MCS关联的目标码率或频谱效率，有利于详细地反映信道状态，提高数据速率，CQI 10至15对应MCS 17至22关联的目标码率或频谱效率。在较低的CQI区间，将CQI对应间隔的MCS关联的目标码率或频谱效率，以保证数据传输的可靠性，较粗略地反应信道状态以节省有限的CQI信息。CQI 2至6对应MCS 0，2，4，6，8关联的目标码率或频谱效率，CQI 7，8，9对应MCS 11，13，15关联的目标码率或频谱效率。
例如基于表十二所述第一MCS表格，CQI 2至6依次对应其中MCS 0，2，4，6，8关联的目标码率或频谱效率，CQI 7至9依次对应其中MCS 11，13，15关联的目标码率或频谱效率，CQI 10至15依次对应其中MCS17至22关联的目标码率或频谱效率。一个CQI表格如表十四所示。
