相关申请的交叉引用
本申请基于申请号为201810589321.8、申请日为2018年06月08日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请实施例涉及通信领域的调制解调技术，尤其涉及一种调制解调方式的调整方法、终端及计算机存储介质。
背景技术
资源元(Resource Element，RE)是长期演进(Long Term Evolution，LTE)中的最小物理资源。一个RE可存放一个调制符号，具体地，调制符号可以通过正交相移键控(Quadrature Phase Shift Keyin，QPSK)、16种符号的相正交振幅调制(Quadrature Amplitude Modulation，QAM)或者64QAM进行调制。其中，QPSK对应的一个RE中存放2比特数据，调制阶数为4，16QAM对应一个RE中存放4比特数据，调制阶数为16，64QAM对应一个RE中存放6比特数据，调制阶数为64。
调制符号的调制阶数越大，解码效率和极限吞吐量也相应越高，然而随着调制阶数的增大，误码率也会增加。因此现有技术中为了提高调制效率而配置较高的调制阶数的方法，在处理数据包小、流量低的实时数据业务时，会存在延时大、误码率高的问题，降低了终端的智能性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。可以理解的是，此处所描述的具体实施例仅仅用于解释相关申请，而非对该申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关申请相关的部分。
从通讯角度来分析，微信、QQ以及直播软件等实时数据业务的相关特性可以包括长连接、小数据包以及低流量，在处理该实时数据业务时需要低延时、低容错以及对无线网络环境变化的较高敏感。
整体分析网络延迟，可以归为以下三方面的原因：
1、应用服务器处理数据带来的延迟，从收到客户端数据包到返回客户端过程的耗时。
2、终端本地对于各种数据运算，画面渲染，处理用户交互行为等工作的过程的耗时。
3、终端传输耗时，包括终端到网络空口的接入网延时，以及从接入网关传输IP数据到应用服务器的过程的耗时。
得益于目前强大的计算处理能力，前两项所造成的延迟都被缩短到一个可控的范围，然而第三项涉及到终端和网络各网元交互，因为无线通信 环境的不确定性，情况复杂，牵涉相关变量多，同时也在整体延时中占比重最大。
LTE是由第三代合作伙伴计划(The 3 rd Generation Partnership Project，3GPP)组织制定的通用移动通信系统(Universal Mobile Telecommunications System，UMTS)技术标准的长期演进，于2004年12月在3GPP多伦多会议上正式立项并启动。LTE系统引入了正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)和多输入多输出(Multi-Input&Multi-Output，MIMO)等关键技术，显著增加了频谱效率和数据传输速率，频谱分配更加灵活，系统容量和覆盖也显著提升。LTE系统网络架构更加扁平化简单化，减少了网络节点和系统复杂度，从而减小了系统时延，也降低了网络部署和维护成本。
RE是LTE中的最小物理资源。一个RE可存放一个调制符号，具体地，调制符号可以通过QPSK、16QAM或者64QAM进行调制。
调制阶数用于计算码型每个符号所能代表的比特数，例如，QPSK，8QAM，16QAM，32QAM等码型的比特数分别是log2(4)，log2(8)，log2(16)，log2(32)，因此这些码型对应的调制阶数分别是2，4，8，16，32。
通常情况下调制符号的阶越高意味着解码效率和极限吞吐量就越高，但是，由于调制阶数越高，从星座图上去理解的话，星座点越来越密，星座点之间的距离降低了，星座点的之间的距离就代表了译码的差错概率，所以调制阶数越高，判决的时候越容易被判定成别的符号，所以误码率也会越高。
在本申请的实施例中，所述一种调制解调方式的调整方法可以应用于以LTE系统的终端，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
本申请实施例提供了一种调制解调方式的调整方法，图1为本申请实施例提出的一种调制解调方式的调整方法的实现流程示意图一，如图1所 示，在本申请的实施例中，上述终端对调制解调方式进行调整的方法可以包括以下步骤：
步骤101、获取当前误码率和当前调制阶数。
在本申请的实施例中，终端可以先获取当前误码率和当前调制阶数。其中，上述终端可以为基于LTE系统的终端，例如，上述终端可以为基于LTE系统的智能手机、平板电脑、便携式移动设备等。
需要说明的是，在本申请的实施例中，上述误码率为有差错的块与数字电路接收的总块数之比。其中，上述误码率可以用于宽带码分多址(Wideband Code Division Multiple Access，W-CDMA)的性能测试。上述误码率是在信道解交错和解码后，由评价各传输块上的循环冗余检验度量。
进一步地，在本申请的实施例中，上述当前调制阶数用于表征上述终端所对应的当前调制解调方式，上述当前调制解调方式为上述终端当前所使用的调制解调方法。具体地，在本申请的实施例中，上述当前调制解调方式可以通过调制解调符号进行表示，例如，上述当前调制解调方式可以为BPSK，QPSK，8QAM，16QAM，32QAM中的任意一个。
进一步地，在本申请的实施例中，上述调制阶数用于计算码型每个符号所能代表的比特数，例如BPSK，QPSK，8QAM，16QAM，32QAM等码型的比特数分别是log2(2)、log2(4)、log2(8)、log2(16)、log2(32)，因此这些码型对应的调制阶数分别是2、4、8、16、32。
进一步地，在本申请的实施例中，终端可以先根据当前数据包对应的特征信息判断是否调整调制解调方式。需要说明的是，在本申请的实施例中，上述终端在处理下行数据业务时，可以为上述终端的上报能力、信道质量上报和基站调度，而基站调度的主要参考来自于上述终端支持的调制解调方式和信道质量，因此，上述终端动态的对调制解调方式进行调谐是控制数据流量的一个主要手段。
需要说明的是，在本申请的实施例中，上述终端可以先获取上述当前 数据包对应的特征信息，然后再根据上述特征信息对是否进行调制解调方式的调整进行判断。其中，在本申请的实施例中，上述特征信息可以为上述当前数据包的多种特征参数，例如，上述特征信息可以为上述当前数据包对应的大小参数、发送间隔参数等。
进一步地，在本申请的实施例中，调制符号的调制阶数越大，解码效率和极限吞吐量也相应越高，然而随着调制阶数的增大，误码率也会增加。因此在处理如微信、QQ以及视频直播等实时数据业务时，终端需要尽可能的降低延时，减小误码率，即需要对调制解调方式进行调整。
需要说明的是，在本发明的实施例中，上述终端在对上述调制解调方式进行调整时，可以为通过改变调制符号对应的调制阶数来调整上述调制解调方式。
进一步地，在本申请的实施例中，上述终端在确定上述当前数据包的上述特征信息之后，可以根据上述特征信息判定上述当前数据包对应的场景，即在调制解调时需要较高阶数的调制符号以达到较高的调制效率，还是在调制解调时需要较低阶数的调制符号以降低误码率，从而减少卡顿。
进一步地，在本申请的实施例中，上述终端在根据上述特征信息判定上述当前数据包对应的场景之后，即可以判断是否对调整调制解调方式进行调整，如果上述终端判定对上述当前调制解调方式进行调整，则可以获取上述当前误码率和上述当前调制阶数。
步骤102、根据当前误码率、当前调制阶数以及预设误码阈值，确定调整模式。
在本申请的实施例中，终端在获取当前误码率和当前调制阶数之后，可以根据上述当年误码率、上述当前调制阶数以及上述预设误码阈值，确定调整模式。其中，上述调整模式可以包括增大阶数和减小阶数，即上述调整模式可以为将上述当前调制阶数进行增大，或者将上述当前调制阶数进行减小。
需要说明的是，在本申请的实施例中，上述终端在获取上述当前误码率之后，可以先将上述当前误码率与上述预设误码阈值进行比较，然后再根据比较结果进一步地确定上述调整模式。
需要说明的是，在本申请的实施例中，上述预设误码阈值为上述终端预先设置的，用于判定对上述终端的上述当前误码率的高低程度进行判定
进一步地，在本申请的实施例中，上述终端在将上述当前误码率与上述预设误码阈值进行比较之后，如果上述当前误码率大于或者等于上述预设误码阈值，那么上述终端可以认为上述当前调制解调方式会造成较大的延时和卡顿，因此需要对调制解调方式进行调整，从而可以进一步根据上述当前调制阶数确定上述调整模式。
进一步地，在本申请的实施例中，上述终端在将上述当前误码率与上述预设误码阈值进行比较之后，如果上述当前误码率小于上述预设误码阈值，那么上述终端可以认为上述当前调制解调方式不会造成较大的延时和卡顿，还可以再对调制效率进行提高，因此需要对调制解调方式进行调整，从而可以进一步根据上述当前调制阶数确定上述调整模式。
步骤103、按照调整模式进行调整处理。
在本申请的实施例中，上述终端在根据上述当年误码率、上述当前调制阶数以及上述预设误码阈值，确定上述调整模式之后，便可以按照上述调整模式进行调整处理。
需要说明的是，在本申请的实施例中，上述终端在确定出上述调整模式之后，如果上述调整模式为降低阶数，那么上述终端便对上述当前调制解调方式进行调整，将上述当前调制阶数减小，例如，如果上述终端对应的当前调制解调方式为64QAM，即当前调制阶数为64，那么上述终端便可以将降低阶数，将调制解调方式调整为16QAM，从而将调制阶数降低为16。
进一步地，在本申请的实施例中，上述终端在确定出上述调整模式之后，如果上述调整模式为升高阶数，那么上述终端便对上述当前调制解调 方式进行调整，将上述当前调制阶数增大，例如，如果上述终端对应的当前调制解调方式为QPSK，即当前调制阶数为4，那么上述终端便可以将增大阶数，将调制解调方式调整为64QAM，从而将调制阶数增大为64。
进一步地，在本申请的实施例中，上述终端可以在确定上述调整模式之后根据上述调整模式生成调整请求，然后将上述调整请求发送至网络侧，网络侧接收到上述调整请求之后，可以先确定上述终端是否为授权用户，如果上述终端是授权用户，那么上述网络侧可以把上述调整请求传递到基站侧，基站侧在接收上述调整请求之后，可以生成并发送与上述调整请求对应的调整响应，网络侧接收上述调整响应之后，可以根据上述调整响应向上述终端发送无线资源控制协议(Radio Resource Control，RRC)重配消息，同时向上述终端下发其它资源重配的信令。上述终端在接收到上述调整响应之后，调整对应的调制解调方式，并配置相关业务信道资源。
进一步地，在本申请的实施例中，上述终端在将上述调整请求发送至网络侧，网络侧接收到上述调整请求之后，可以先确定上述终端是否为授权用户，如果上述终端为非授权用户，那么上述网络侧则不予理会。
本申请实施例提出的一种调制解调方式的调整方法，终端获取当前误码率和当前调制阶数；其中，当前调制阶数用于表征当前调制解调方式；根据当前误码率、当前调制阶数以及预设误码阈值，确定调整模式；按照调整模式进行调整处理。由此可见，在本申请的实施例中，终端可以根据当前误码率和预设误码率阈值对当前调制阶数进行调整，即对当前调制解调方式进行实时调整，从而可以在误码率较高时，降低当前调制阶数，以接收较小的数据包，从而获得更好的解码成功率，进而有效地减小延时，大大降低误码率，进一步提高终端的智能性。
实施例二
基于上述实施例一，在本申请的实施例中，上述终端根据所述当前误码率、所述当前调制阶数以及预设误码阈值，确定调整模式的方法可以包 括以下步骤：
步骤102a、将当前误码率与预设误码阈值进行对比，获得对比结果。
在本申请的实施例中，终端在获取当前误码率和当前调制阶数之后，可以先将上述当前误码率和上述预设误码阈值进行对比，从而便可以获得上述当前误码率和上述预设误码阈值对应的上述对比结果。
进一步地，在本申请的实施例中，上述终端在将上述当前误码率和上述预设误码阈值进行对比之后，所获得的对比结果可以为上述当前误码率大于或者等于上述预设误码阈值，也可以为上述当前误码率小于上述预设误码阈值。
进一步地，在本申请的实施例中，如果上述对比结果为上述当前误码率大于或者等于上述预设误码阈值，那么上述终端可以认为上述当前调制解调方式会造成较大的延时和卡顿，即可以认为上述调制阶数较大，因此需要对调制解调方式进行调整，从而可以进一步根据上述当前调制阶数确定上述调整模式。
进一步地，在本申请的实施例中，如果上述当前误码率小于上述预设误码阈值，那么上述终端可以认为上述当前调制解调方式不会造成较大的延时和卡顿，因此既可以不对上述当前调制阶数进行改变，也可以增大上述当前调制阶数，从而还可以再对调制效率进行提高。
步骤102b、根据对比结果和当前调制阶数，确定调整模式。
在本申请的实施例中，终端在将上述当前误码率和上述预设误码阈值进行对比，获得上述当前误码率和上述预设误码阈值对应的上述对比结果之后，可以继续根据上述对比结果和上述当前调制阶数，确定出相应地上述调制模式。
进一步地，在本申请的实施例中，如果上述对比结果为上述当前误码率大于或者等于上述预设误码阈值，上述终端根据上述对比结果和上述当前调制阶数确定上述调整模式的具体方式可以为：当上述当前调制阶数大 于第一预设阶数阈值时，确定上述调整模式为减小阶数。
需要说明的是，在本申请的实施例中，如果上述对比结果为上述当前误码率大于或者等于上述预设误码阈值，上述终端可以再对上述当前调制阶数和上述第一预设阶数阈值进行比较，如果上述第一预设阶数阈值大于上述当前调制阶数，那么上述终端便可以确定上述调整模式为减小阶数。
需要说明的是，在本申请的实施例中，上述第一预设阶数阈值为上述终端预先设定的、用于表征调制阶数下限的数值。例如，上述终端可以预先设定上述第一预设阶数阈值为4，那么，如果上述当前调制解调方式为16QAM，即上述当前调制阶数为16，由于上述当前调制阶数大于上述第一预设阶数阈值，上述终端便可以确定上述调整模式为减小阶数。
进一步地，在本申请的实施例中，如果上述对比结果为上述当前误码率大于或者等于上述预设误码阈值时，上述终端可以再对上述当前调制阶数和上述第一预设阶数阈值进行比较，如果上述第一预设阶数阈值大于上述当前调制阶数，那么上述终端便可以确定不对上述当前调制阶数进行调整。
进一步地，在本申请的实施例中，如果上述第一预设阶数阈值为4，上述当前调制解调方式为BPSK，即上述当前调制阶数为2，由于上述当前调制阶数小于上述第一预设阶数阈值，上述终端便可以确定不对上述当前调制阶数进行调整。
进一步地，在本申请的实施例中，如果上述对比结果为上述当前误码率小于上述预设误码阈值，上述终端根据上述对比结果和上述当前调制阶数确定所述调整模式的具体方式可以为：当上述当前调制阶数小于第二预设阶数阈值时，确定所述调整模式为增大阶数。
需要说明的是，在本申请的实施例中，如果上述对比结果为上述当前误码率小于上述预设误码阈值，上述终端可以再对上述当前调制阶数和上述第二预设阶数阈值进行比较，如果上述第二预设阶数阈值小于上述当前 调制阶数，那么上述终端便可以确定上述调整模式为增大阶数。
需要说明的是，在本申请的实施例中，上述第二预设阶数阈值大于上述第一预设阶数阈值，上述第二预设阶数阈值为上述终端预先设定的、用于表征调制阶数上限的数值。例如，上述终端可以预先设定上述第二预设阶数阈值为64，那么，如果上述当前调制解调方式为16QAM，即上述当前调制阶数为16，由于上述当前调制阶数小于上述第二预设阶数阈值，上述终端便可以确定上述调整模式为增大阶数。
进一步地，在本申请的实施例中，如果上述对比结果为上述当前误码率小于上述预设误码阈值时，上述终端可以再对上述当前调制阶数和上述第二预设阶数阈值进行比较，如果上述第二预设阶数阈值小于上述当前调制阶数，那么上述终端便可以确定不对上述当前调制阶数进行调整。
进一步地，在本申请的实施例中，如果上述第二预设阶数阈值为32，上述当前调制解调方式为64QAM，即上述当前调制阶数为64，由于上述当前调制阶数大于上述第二预设阶数阈值，上述终端便可以确定不对上述当前调制阶数进行调整。
本申请实施例提出的一种调制解调方式的调整方法，终端获取当前误码率和当前调制阶数；其中，当前调制阶数用于表征当前调制解调方式；根据当前误码率、当前调制阶数以及预设误码阈值，确定调整模式；按照调整模式进行调整处理。由此可见，在本申请的实施例中，终端可以根据当前误码率和预设误码率阈值对当前调制阶数进行调整，即对当前调制解调方式进行实时调整，从而可以在误码率较高时，降低当前调制阶数，以接收较小的数据包，从而获得更好的解码成功率，进而有效地减小延时，大大降低误码率，进一步提高终端的智能性。
