应理解，本申请对网络设备和终端的具体形式均不作限定。
为了便于理解，以下结合图1和图2对适用于本申请实施例提供的数据传输方法的通信系统进行简单说明。
图1是适用于本申请实施例提供的数据传输方法的通信系统100的示意图。如图1所示，该通信系统100中包括云端服务器、UPF、基站、终端以及NEF、SMF、PCF等网元。云端服务器可以对视频源解码和渲染等。其中，终端可以是头显XR眼镜、视频播放器和全息投影仪等设备。
在上述通信系统100中，数据、指令或信号可以由云端服务器传输给UPF，UPF可以通过基站将这些数据、信令、指令或信号传输给终端，终端接收到这些数据、信令、指令或信号后，可以通过基站向UPF反馈一些数据或信息，UPF再将这些数据或信息传输到云端服务器。
应理解，在该通信系统100中，云端服务器、UPF或基站等可以具有本申请实施例中网络设备所具有的功能，例如，该通信系统100中，云端服务器具有本申请实施例中网络设备具有的功能，则云端服务器发出的第一信息、第三信息或第四信息可以由UPF和基站等网络传输过程中的中间网元转发给终端。又例如，该通信系统100中，基站具有本申请实施例中网络设备具有的功能，则基站发出的第一信息、第三信息或第四信息可以直接发送给终端。第一信息、第三信息或第四信息在下文中有详细的描述，此处暂不赘述。还应理解，在该通信系统100中，对网络设备和终端的具体形式均不作限定，该通信系统100以及上述数据传输过程只是示例性的，不应对本申请产生任何限定。
图2是适用于本申请实施例提供的数据传输方法的通信系统200的示意图。如图2所示，该通信系统200中包括云端服务器、终端以及无线保真(wireless fidelity，Wi-Fi)路由器或Wi-Fi AP。
在上述通信系统200中，云端服务器可以将数据、信令、指令或信息发送到Wi-Fi路由器或Wi-Fi AP等无线接入网设备，再由这些无线接入网设备发送给终端，终端接收到这些数据、信令、指令或信息，可以将一些反馈数据或信息发送到无线网络设备，无线网络设备可以再发送到云端服务器。例如，云端服务器可以将XR媒体数据或者普通视频通过Wi-Fi路由器或Wi-Fi AP等传送到XR终端，XR终端也可以将反馈信息通过原路发送给云端服务器。
应理解，在该通信系统200中，云端服务器或Wi-Fi路由器或Wi-Fi AP具有本申请实施例中网络设备所具有的功能。例如，云端服务器具有本申请实施例中网络设备所具有的功能，则云端服务器发出的第一信息、第三信息或第四信息可以通过Wi-Fi路由器或Wi-Fi AP转发给终端。又例如，Wi-Fi路由器或Wi-Fi AP具有本申请实施例中网络设备所具有的功能，则Wi-Fi路由器或Wi-Fi AP发出的第一信息、第三信息或第四信息可以直接发送给终端。第一信息、第三信息或第四信息在下文中有详细的描述，此处暂不赘述。还应理解，在该通信系统200中，对网络设备和终端的具体形式均不作限定，该通信系统200以及上述数据传输过程只是示例性的，不应对本申请产生任何限定。
图3为XR视频的传输示意图。图3所示的XR视频传输可以是在例如图1所示的通信系统100中传输的示意图。XR视频可以由多个视频帧构成，该XR视频例如可以是由图1中的云端服务器发送的，也即，上述云端服务器可以为该XR视频的发送端。与此对应，该XR的视频的接收端可以是图1中的终端。在图3中，XR视频的一个画面帧可以在发送端的网络传输层被分成几十个IP数据包，传输到核心网，之后IP数据包再经过RAN传输到接收端。应理解，图3中示出的XR视频的传输过程只是示例性的，不应对本申请产生任何限定。
由于网络传输的不确定性，可能会出现帧传输错误和帧传输延时等问题，从而影响用户的体验感受。然而，由于不同终端对用户体验的衡量方式不同，网络设备无法精准地根据用户体验调整通信行为，导致系统效率较低，用户体验不佳。
因此，本申请提供了一种数据传输方法，网络设备可以通过第一信息为终端配置用来确定网络传输状况对用户体验的影响的用户体验评价模式，终端可以基于网络设备配置的用户体验评价模式得到网络传输状况对用户体验的影响信息。使得网络设备能够根据终端反馈的用户体验，精准地调整与终端的通信行为，进而提高用户的体验感。
为了更好地理解本申请实施例提供的数据传输方法，首先对本申请中涉及到的术语作简单说明。
1、帧传输错误：也可以称为误帧，帧传输过程中发生错误。如果在传输过程中视频帧所包括的一个数据包出错，则整幅画面帧均无法正确解码。
2、帧传输延时：帧传输过程中发生的延时情况。例如，记每个帧的首包到达的时间为t1，尾包到达的时间为t2，则T＝t2-t1可用于衡量该帧在网络侧的传输的时延，若该时延超过该帧的最大的帧时延预算(frame delay budget，FDB)和终端缓存处理能力时延的和，则会出现跳帧现象，即，给定参考位置的帧未到。
图4为帧传输过程的示意性图。如图4所示，图4示出了6个视频帧到达的情况。每个视频帧可以承载于多个IP数据包中，图中的每一个矩形框可以表示一个IP数据包。可以看到，图中的第2帧中存在IP数据包传输错误，导致第2帧传输错误。第4帧中存在IP数据包传输错误，导致第4帧传输错误，且第4帧还存在IP数据包在处理显示时刻未到达，导致第4帧传输延时。第5帧也存在IP数据包在处理显示时刻未到达，导致第5帧传输延时。
3、平均主观意见分(MOS)：是目前普遍公认的语音视频质量主观测量方法，通过MOS可以得到比较真实的听觉视觉质量分数。
图5为XR-MOS的示意性分解图。如图5所示，可以从视频源、网络传输和终端三个角度获取XR-MOS。其中，网络传输可以包括接入网传输和核心网传输两部分。
一种可能的实现方式为：XR-MOS可以由视频源-MOS、网络传输-MOS和终端-MOS三部分以最简单的线性叠加得到，如：XR-MOS＝视频源-MOS+网络传输-MOS+终端-MOS。
其中，云端服务器可以定义视频源-MOS，视频源-MOS的影响因素包括：画质、帧率、清晰度和音频质量等；网络设备可以定义网络传输-MOS，网络传输-MOS的影响因素包括：网络侧的传输能力、时延预算(packet delay budget，PDB)和误包率(packet  error rate，PER)等；终端可以定义终端-MOS，终端-MOS的影响因素包括：终端支持的视场角(field of view，FOV)角度、终端刷新率、续航能力、佩戴舒适度和缓存处理能力等。
应理解，图5中示出的XR-MOS的分解图只是示例性的，不应对本申请产生任何限定。
4、扩展现实质量评价分数：也可以称为扩展现实质量指数(XQI)。XQI是本申请提出的用于评价网络传输对用户体验的影响。其基本原则是在网络传输侧尽可能利用网络传输中可获得的统计数据和信源和/或终端侧的相关信息来逼近用户对XR业务的主观体验评价。换言之，由于网络传输MOS是人的主观评价值，网络传输-MOS不能直接获得，因此，假设在视频源-MOS和终端-MOS已知的情况下，提出XQI，以期通过获得网络侧的一些统计数据来使得计算出的XQI尽量与网络传输-MOS较好的拟合。
XQI可以分为两部分：画质体验评分和交互体验评分。也即，用户体验XQI值可以通过综合画质体验评分和交互体验评分得到。其中，画质体验评分主要与网络传输统计的包错误情况、传输块(transmission block，TB)错误情况、帧率、图像组(group of picture，GOP)的大小等信源相关参数相关；交互体验评分主要与网络传输统计的包达到情况、包时延、帧率、GOP和终端缓存处理能力等信源或终端相关参数相关。
XQI可以有多种不同的定义形式，例如，可以利用公式、神经网络或表格等不同的形式定义XQI。也可以理解为获得XQI的值可以有多种不同的模式，对应于上述的几种形式可以为公式模式、神经网络模式或表格模式等，这些模式也可以统称为用户体验评价模式。应理解，用户体验评价模式不限于上述公式模式、神经网络模式和表格模式，用户体验评价模式还可以有其他形式，本申请对此不作任何限定。
示例性地，用户体验评价模式为公式模式时，XQI的计算公式可以为：XQI＝XQI 1+XQI 2。
其中，XQI 1可以表示画质体验评分，例如，XQI 1的计算公式可以为：
Figure PCTCN2022091804-appb-000001
α表示计算系数；FR表示视频帧的帧率(frame rate，FR)，即每秒中显示视频帧的数据量，例如每秒传输帧数(frames per second，FPS)为60帧；R ave表示每个GOP内的帧损伤率计算统计周期内所有GOP的平均帧损伤率。一个GOP内的帧损伤率的计算公式可以为
Figure PCTCN2022091804-appb-000002
其中N表示GOP的大小，i表示当前GOP中第一个传输错误的帧位置。
XQI 2可以表示交互体验评分，例如，XQI 2的计算公式可以为：
Figure PCTCN2022091804-appb-000003
β表示计算系数；FR表示视频帧的帧率；Q ave表示统计周期内所有GOP的平均跳帧率，一个GOP内的跳帧率的计算公式可以为
Figure PCTCN2022091804-appb-000004
M表示GOP内发生跳帧的数量，N表示GOP的大小；T表示一个N维的向量，其各个元素表示GOP内各个视频帧在网络传输所造成的时延。
也即，XQI的计算公式可以为：
Figure PCTCN2022091804-appb-000005
应理解，上述XQI、XQI 1、XQI 2、R ave和Q ave等的计算公式只是示例性的，不应对本申请产生任何限定。
示例性地，用户体验评价模式为神经网络模式时，可以利用一些典型视频集合经过网络传输后的帧的到达情况和相应的评分情况(例如，专家打分等形式)作为训练集，得到一个基于帧的到达情况，也即，综合考虑了帧传输错误情况和帧传输延时情况获取XQI的值的神经网络。例如，图6是基于帧的到达情况构建的XQI的神经网络示意图。图中的C 1、C 2、C 3、C 4、C 5和C 6表示权重，f 1(e)、f 2(e)、f 3(e)、f 4(e)、f 5(e)和f 6(e)表示神经元。应理解，神经元也就是神经网络中的节点，每个节点可以代表一种特定的输出函数。
当然，也可以分别根据帧传输错误情况和帧传输延时情况构建相应的神经网络模式。例如，图7是基于帧传输错误情况构建的XQI 1的神经网络示意图。图中的XQI 1可以表示画质体验评分，C 7、C 8、C 9、C 10、C 11和C 12表示权重，g 1(e)、g 2(e)、g 3(e)、g 4(e)、g 5(e)和g 6(e)表示神经元。又例如，图8是基于帧传输延时情况构建的XQI 2的神经网络示意图。图中的XQI 2可以表示交互体验评分，C 13、C 14、C 15、C 16、C 17和C 18表示权重，h 1(e)、h 2(e)、h 3(e)、h 4(e)、h 5(e)和h 6(e)表示神经元。
应理解，图6、图7和图8示出的各神经网络示意图中的权重和神经元是相互独立的，可以相同，也可以不同，本申请对此不作限定。还应理解，图6、图7和图8中的神经网络示意图仅为示例性的，不应对本申请产生任何限定。例如，在实际的实现方式中，神经元的个数可以更多或更少，本申请对此也不作任何限定。
示例性地，用户体验评价模式为表格模式时，综合考虑了帧传输错误情况和帧传输延时情况，也即，XQI的值取决于帧传输错误情况和帧传输延时情况。
例如，表1中示出了XQI的值与帧传输错误情况和帧传输延时情况的对应关系。
表1
Figure PCTCN2022091804-appb-000006
Figure PCTCN2022091804-appb-000007
表1中用PER来近似表征帧传输错误的情况，用PDB来近似表征帧传输演示的情况。在表1中，第一行可以表示PDB的不同取值，第一列可以表示PER的不同取值，第二行第二列到第六行第六列可以表示不同的PER取值和不同的PDB取值对应时，XQI的取值。例如，当PDB为“5毫秒(ms)”，且PER为“0.03”时，可以直接在表中找到XQI的值为“82”。
应理解，表1所示的用于表示PER、PDB与XQI的对应关系的形式只是示例性的，该对应关系并不限于表格来表征。还应理解，表中PER、PDB与XQI的对应值也只是示例性的，不应对本申请产生任何限定。
5、调制编码方案(MCS)：MCS将所关注的影响通讯速率的因素作为表的列，将MCS索引作为行，形成一张速率表。所以，每一个MCS索引其实对应了一组参数下的物理传输速率。例如，表2中示出了MCS的不同索引与调制阶数、目标码速和频谱效率的一种可能的对应关系。
表2
Figure PCTCN2022091804-appb-000008
Figure PCTCN2022091804-appb-000009
6、信道质量指示(CQI)：CQI能够表示当前信道质量的好坏，CQI与信道的信噪比大小相对应。CQI的取值范围为0～31，当CQI的取值为0时，信道质量最差；当CQI的取值为31时，信道质量最好。一般CQI常见的取值范围为12～24。CQI的值可以由终端上报给网络设备的。例如，表3中示出了CQI的不同值与调制方案、码速和效率的一种可能的对应关系。
表3
Figure PCTCN2022091804-appb-000010
在表3中，CQI的不同取值可以对应于不同的调制方案、码速和效率。表3中示例性地列举出了“QPSK”、“16QAM”和“64QAM”等调制方案，其中，“QPSK” 表示正交相移键控(quadrature phase shift keying，QPSK)，“QAM”表示正交振幅调制(quadrature amplitude modulation，QAM)。
下面将结合附图对本申请实施例提供的数据传输方法做详细说明。
为方便理解，做出以下说明：
第一，第一、第二等仅为便于区分不同的对象，不应构成任何限定。例如，第一信息、第二信息、第三信息和第四信息，并不一定限定发送的先后顺序，而只是为了区分这些信息包含的内容不同。
图9是适用于本申请实施例提供的数据传输方法1000的流程示意图。如图9所示，该方法1000可以包括步骤1010至步骤1040。下面对方法1000中的各个步骤做详细说明。
在步骤1010中，网络设备向终端发送第一信息。相应地，终端接收来自网络设备的第一信息。
第一信息用于配置用户体验评价模式。用户体验评价模式是多种用户体验评价模式中的一种，用户体验评价模式用于评价网络传输对用户体验的影响。
前已述及，XQI用于评价网络传输对用户体验的影响，获得XQI的值可以有多种不同的模式，例如，公式模式、神经网络模式或表格模式等。
另外，前已述及，XQI可以分为两部分：画质体验评分和交互体验评分。用户体验评价模式包括画质体验评价模式和交互体验评价模式，画质体验评价模式用于评价传输错误对画质体验的影响，交互体验评价模式用于评价传输延时对交互体验的影响。
在一种可能的实现方式中，终端可以预先存储多种用户体验评价模式。
可选地，终端预先存储的多种用户体验评价模式可以为综合了传输错误对画质体验的影响和传输延时对交互体验的影响为一体的用户体验评价模式，即，存储获得XQI一个值的多种用户体验评价模式。
例如，多种用户体验评价模式中的每一种用户体验评价模式可以对应一个索引值，用户体验评价模式和索引值可以以表格的形式存储在终端上。
例如，表4中示出了多种用户体验评价模式与索引的对应关系。
表4
Figure PCTCN2022091804-appb-000011
当然，画质体验评价模式和交互体验评价模式也可以分开来配置。例如，表5示 出了多种画质体验评价模式与索引的对应关系。表6中示出了多种交互体验评价模式与索引的对应关系。
表5
Figure PCTCN2022091804-appb-000012
表6
Figure PCTCN2022091804-appb-000013
终端在向网络设备请求XR业务后，网络设备识别到终端XR业务请求后，可以通过信令向终端发送第一信息，第一信息可以包括某种用户体验评价模式对应的索引值，以此来配置终端可以使用的用户体验评价模式。
当然，终端也可以以其他的形式预先存储多种用户体验评价模式，并不限定于上述表4、表5和表6等表格的形式存储用户体验评价模式与索引的对应关系。
应理解，在表4、表5和表6中，公式模式和神经网络模式中的系数或参数可以是预先设定的已知的具体数值，如公式中的α和β可以是预先设定的具体数值。
可选地，第一信息还可以用于配置用户体验评价模式的参数。
若终端预先存储的多种用户体验评价模式为含有待定参数的用户体验评价模式，例如，公式模式和神经网络模式等中含有待定参数，则第一信息中还可以包括某种用户体验评价模式所含有的待定参数的具体取值。也即，第一信息中可以用于指示某种用户体验评价模式的索引和该用户体验评价模式中含有的待定参数的具体取值。
可选地，网络设备可以向终端发送第三信息，第三信息用于配置用户体验评价模式的参数。
终端在向网络设备请求XR业务后，网络设备识别到终端XR业务请求后，可以通过信令向终端发送第一信息，第一信息可以包括某种用户体验评价模式，以此来配置终端可以使用的含有待定参数的用户体验评价模式，网络设备还可以通过信令向终 端发送第三信息，第三信息可以用于指示配置的含有待定参数的用户体验评价模式的参数的具体数值，以此来配置该终端被指定使用的含有待定参数的用户体验评价模式的参数。
还应理解，上述述及到的第一信息的承载信令可以是无线资源控制(radio resource control，RRC)信令或下行控制信息(downlink control information，DCI)或系统信息块(system information block，SIB)，上述述及到的第三信息的承载信令可以是RRC信令或DCI。本申请对此不作任何限定。
在步骤1020中，终端基于第一信息确定用户体验评价模式。
终端接收来自网络设备的第一信息，并可以基于第一信息确定用户体验评价模式。
一种可能的实现方式，终端可以以如表4所示的形式预先存储了多种不含待定参数的用户体验评价模式和索引的对应关系。终端接收来自网络设备的第一信息，此时第一信息可以用于指示某种不含待定参数的用户体验评价模式对应的索引，或者，第一信息中包括某种不含待定参数的用户体验评价模式对应的索引，终端可以根据索引确定可以使用的某种不含待定参数的用户体验评价模式。
例如，第一信息中指示出的索引为1，则对应于终端预先存储的表4中，终端可以确定用户体验评价模式为公式模式：
Figure PCTCN2022091804-appb-000014
其中，α和β的具体数值已知。
另一种可能的实现方式，终端可以以如表4所示的形式预先存储了多种含有待定参数的用户体验评价模式和索引的对应关系。终端接收来自网络设备的第一信息，此时第一信息可以用于指示某种含有待定参数的用户体验评价模式对应的索引和待定参数的具体取值，或者，第一信息中包括某种含有待定参数的用户体验评价模式对应的索引和待定参数的具体取值，终端可以根据索引和待定参数的具体取值确定可以使用的某种含有待定参数的用户体验评价模式。在这种实现方式中，终端可以基于第一信息确定用户体验评价模式的参数。
例如，第一信息中指示出的索引为1，则对应于终端预先存储的表4中，终端可以确定用户体验评价模式为公式模式：

应理解，对于不同的终端，网络设备可以根据各个终端不同的业务需求，通过信令向终端配置不同的待定参数的具体数值。也可以理解为，网络设备向不同的终端发送的第一信息或第三信息中包含或用于指示的待定参数的具体数值可以不同。
在步骤1030中，终端向网络设备发送第二信息。相应地，网络设备接收来自终端 的第二信息。
应理解，第二信息包含网络传输对用户体验的影响的信息。网络传输对用户体验的影响的信息包括画质体验评价信息和交互体验评价信息，画质体验评价模式用于画质体验评价信息的确定，交互体验评价模式用于交互体验评价信息的确定。网络传输对用户体验的影响的信息用于指示扩展现实质量评价分数，画质体验评价模式和交互体验评价模式用于扩展现实质量评价分数的确定。
一种可能的实现方式，终端向网络设备发送的第二信息所包含网络传输对用户体验的影响的信息可以用于指示扩展现实质量评价分数。也可以理解为，终端向网络设备发送扩展现实质量评价分数，也即，终端向网络设备发送XQI的值。
应理解，在终端向网络设备发送扩展现实质量评价分数之前，终端可以先确定扩展现实质量评价分数，也即，终端可以先确定XQI的值。例如，上述所述的终端基于第一信息或基于第一信息和第三信息得到的XQI的值，为了简洁，此处不再赘述。
可选地，终端可以基于画质体验评价模式和交互体验评价模式确定扩展现实质量评价分数。
例如，终端以如表5所示的形式预先存储了多种不含待定参数的画质体验评价模式和索引的对应关系，以及如表6所示的形式预先存储了多种不含待定参数的交互体验评价模式和索引的对应关系，终端接收来自网络设备的第一信息，第一信息指示出确定画质体验评价模式的索引为1，确定交互体验评价模式的索引为2，则终端根据索引确定画质体验模式为公式模式：

其中，α的具体取值已知，根据该公式计算出XQI 1；终端根据索引确定交互体验模式为神经网络模式：基于帧传输延时情况构建的XQI 2的神经网络，基于该神经网络得到XQI 2。再根据终端预先存储的XQI与XQI 1和XQI 2的关系，例如上文述及到的公式：XQI＝XQI 1+XQI 2，计算得到XQI的值，也即，得到扩展现实质量评价分数。
另一种可能的实现方式，终端向网络设备发送的第二信息，第二信息包含的网络传输对用户体验的影响的信息包括画质体验评价信息和交互体验评价信息，画质体验评价信息用于指示传输错误对画质体验的影响系数或评价分数，交互体验评价信息用于指示传输延时对交互体验的影响系数或评价分数。也可以理解为，终端向网络设备发送传输错误对画质体验的影响系数或评价分数，和，传输延时对交互体验的影响系数或评价分数。
应理解，在终端向网络设备发送传输错误对画质体验的影响系数或评价分数，和，传输延时对交互体验的影响系数或评价分数之前，终端可以基于画质体验评价模式确定画质体验评价信息，基于交互体验评价模式确定交互体验评价信息。
例如，终端在得到了XQI的值的情况下，假设在一个统计周期内所有的帧均接收正确的情况下XQI的值为XQI a，则传输错误对画质体验的影响系数w 1的计算公式可以为：
Figure PCTCN2022091804-appb-000020
又例如，终端在得到了XQI的值的情况下，假设在一个统计周期内所有的帧均在时延约束内被终端接收到的情况下，XQI的值为XQI b，则传输延时对交互体验的影响系数w 2的计算公式可以为：
Figure PCTCN2022091804-appb-000021
例如，在图4中，第1帧、第3帧和第6帧可以正常显示，第2帧传输错误，第4帧传输错误且传输延时，第5帧传输延时，在这种情况下可以基于第一信息得到对应的XQI的真实值。假设在一个统计周期内的帧均接收正确，则第1帧、第2帧、第3帧和第6帧可以正常显示，第4帧和第5帧传输延时，在这种假设的前提下，XQI的值为XQI a，此时w 1可以用于表示帧传输错误对XQI的影响；假设一个统计周期内的帧均在时延约束内被终端接收到，则第1帧、第3帧、第5帧和第6帧可以正常显示，第2帧和第4帧传输错误，在这种假设的前提下，XQI的值为XQI b，此时w 2可以用于表示传输延时对XQI的影响。
因此，在终端确定了XQI的值、XQI a的值和XQI b的值情况下，终端向网络设备发送传输错误对画质体验的影响系数w 1，和，传输延时对交互体验的影响系数w 2；或，终端向网络设备发送传输错误对画质体验的影响系数w 1，和，交互体验评价分数；或，终端向网络设备发送画质体验评价分数，和，传输延时对交互体验的影响系数w 2；或，终端向网络设备发送画质体验评价分数，和，交互体验评价分数。

在步骤1040中，网络设备基于第二信息，与终端进行通信。
网络设备根据终端发来的第二信息，可以调整与终端的通信行为，例如，降低MCS和/或提高调度优先级。
网络设备可以基于第二信息和CQI，确定用于与终端进行通信的MCS，终端接收来自网络设备的第四信息，第四信息用于指示MCS，MCS与所述第二信息和CQI相关，因此网络设备和终端可以基于MCS进行通信。
应理解，上述述及到的第四信息的承载信令可以是DCI。
一种可能的实现方式，当终端向网络设备发送的是XQI的值时，网络设备基于该XQI的值调整与终端的通信行为，基于调整后的通信行为与终端进行通信。
如果当前XQI的值小于目标XQI的值，网络设备则可以通过降低MCS和/或提高调度优先级，基于降低后的MCS和/或提高后的调度优先级与终端进行通信。
可以结合XQI的值和CQI来确定降低后的MCS。例如，可以根据公式：
Figure PCTCN2022091804-appb-000024
来确定降低后的MCS，其中，I 1表示当前的MCS索引，I 2表示降低后的MCS索引，XQI 0表示所述目标XQI的值，XQI表示当前XQI的值。
上文已述及，CQI的值可以由终端上报给网络设备，当网络设备接收到终端发来的CQI的值后，网络设备可以先根据CQI与MCS的映射关系，确定当前的MCS索引。例如，若终端发给CQI的值为3，XQI的值为70，而目标XQI的值为80时，此时，根据表3，可以确定当前的码速为193，而在表2中，码速193对应的MCS索引为3，即，I 1的取值为4，XQI 0的取值为80，则根据上述公式，计算得到的I 2为2。
XQI的值与XQI 0的差值越大，需要将调度优先级提高的幅度越大；XQI的值与XQI 0的差值越小，需要将调度优先级提高的幅度越小。
另一种可能的实现方式，当终端向网络设备发送的是w 1和w 2时，网络设备基于w 1和w 2调整与终端的通信行为，基于调整后的通信行为与终端进行通信。
网络设备可以根据w 1的值来降低MCS，基于降低后的MCS与终端进行通信；和/或，可以根据w 2提高调度优先级，基于调整后的调度优先级与终端进行通信。
可以结合w 1的值和CQI来确定降低后的MCS。例如，可以根据公式：
Figure PCTCN2022091804-appb-000025
来确定降低后的MCS，其中，I 1表示当前的MCS索引，I 2表示降低后的MCS索引，w 1为传输错误对画质体验的影响系数。
可以根据w 2调整调度优先级，w 2的值越大，需要将调度优先级提高的幅度越大；w 2的值越小，需要将调度优先级提高的幅度越小。
又一种可能的实现方式，当终端向网络设备发送的是XQI 1和XQI 2时，网络设备基于XQI 1和XQI 2调整与终端的通信行为，基于调整后的通信行为与终端进行通信。
如果当前XQI 1的值小于目标画质体验评价分数
Figure PCTCN2022091804-appb-000026
的值时，网络设备则可以根据XQI 1的值降低MCS，基于降低后的MCS与终端进行通信；以及，当前XQI 2的值小于目标交互体验评价分数
Figure PCTCN2022091804-appb-000027
的值时，可以根据XQI 2提高调度优先级，基于调整后的调度优先级与终端进行通信。
可以结合XQI的值和CQI来确定降低后的MCS。例如，可以根据公式：

来确定降低后的MCS，其中，I 1表示当前的MCS索引，I 2表示降低后的MCS索引，
Figure PCTCN2022091804-appb-000029

可以根据XQI 2调整调度优先级，XQI 2与

的差值越大，需要将调度优先级提高的幅度越大；XQI 2与
