可选的,核心网设备可以由一个设备中的一个或多个功能模块实现,也可以由多个设备共同实现,本申请实施例对此不作具体限定。可以理解的是,上述功能模块既可以是硬件设备中的网络元件,也可以是在专用硬件上运行的软件功能模块,或者是平台(例如,云平台)上实例化的虚拟化功能模块。
为了方便理解,以下对本申请实施例涉及的一些内容进行解释说明:
1、人工智能(Artificial Intelligence,AI)
人工智能(AI)目前在各个领域获得了广泛的应用,将人工智能融入无线通信网络,显著提升吞吐量、时延以及用户容量等技术指标是未来的无线通信网络的重要任务。AI模块有多种实现方式,例如神经网络、决策树、支持向量机、贝叶斯分类器等。本申请实施例以神经网络为例进行说明,但是并不限定AI模块的具体类型。
一个神经网络的示意图2所示:
其中,神经网络由神经元组成,神经元的示意图如图3所示。其中a1,a2,…aK为输入,w为权值(乘性系数),b为偏置(加性系数),σ(.)为激活函数。常见的激活函数包括Sigmoid、tanh、线性整流函数或修正线性单元(Rectified Linear Unit,ReLU)等等。
神经网络的参数通过梯度优化算法进行优化。梯度优化算法是一类最小化或者最大化目标函数(或描述为损失函数)的算法,而目标函数往往是模型参数和数据的数学组合。例如给定数据X和其对应的标签Y,构建一个神经网络模型f(.),有了模型后,根据输入x就可以得到预测输出f(x),并且可以计算出预测值和真实值之间的差距(f(x)-Y),这个就是损失函数。找到合适的W,b使上述的损失函数的值达到最小,损失值越小,则说明模型越接近于真实情况。
目前常见的优化算法,基本都是基于误差反向传播(error Back Propagation,BP)算法。BP算法的基本思想是,学习过程由信号的正向传播与误差的反向传播两个过程组成。正向传播时,输入样本从输入层传入,经各隐层逐层处理后,传向输出层。若输出层的实际输出与期望的输出不符,则转入误差的反向传播阶段。误差反传是将输出误差以某种形式通过隐层向输入层逐层反传,并将误差分摊给各层的所有单元,从而获得各层单元的误差信号,此误差信号即作为修正各单元权值的依据。这种信号正向传播与误差反向传播的各层权值调整过程,是周而复始地进行的。权值不断调整的过程,也就是网络的学习训练过程。此过程一直进行到网络输出的误差减少到可接受的程度,或进行到预先设定的学习次数为止。
一般而言,根据解决类型不同,选取的AI算法和采用的AI模型也有所差别。相关技术中,借助AI提升5G网络性能的主要方法是通过基于神经网络的算法和AI模型增强或者替代目前已有的算法或处理模块。在特定场景下,基于神经网络的算法和AI模型可以取得比基于确定性算法更好的性能。比较常用的神经网络包括深度神经网络、卷积神经网络和循环神经网络等。借助已有AI工具,可以实现神经网络的搭建、训练与验证工作。
相关技术中,AI在无线环境建模、信号检测、信道估计、波束成型、定位、移动性管理、无线资源分配、流量预测,以及网络状态跟踪和智能调度等复杂的通信任务中均能获得比传统方法更优的性能。相关技术中,3GPP已经有用于操作维护管理(Operation Administration and Maintenance,OAM)的AI/ML(AI/ML for OAM)、用于下一代无线接入网(Next Generation Radio Access Network,NG-RAN)的AI/ML(AI/ML for NG-RAN)、5G第三阶段网络自动化的推动者(Enablers for Network Automation for 5G-Phase 3)、5G系统支持基于AI/ML的服务(5G Systems Support for AI/ML-based Services)和用于空中接口的AI/ML(AI/ML for Air Interface)等多个项目开展了无线AI标准化研究,具体研究方向为:
AI/ML for OAM主要研究了管理数据分析服务(management data analytics service,MDAS)。
Enablers for Network Automation for 5G-Phase 3和5G Systems Support for AI/ML-based Services是核心网中引入AI的项目,R18阶段主要研究AI模型共享、支持联邦学习、NWDAF的增强、5G系统辅助AI/ML模型实现智能传输和提供传输保障。
AI/ML for NG-RAN在R17阶段研究了网络节能、负载均衡和移动性优化等三个用例和基础的功能框架。在R18阶段主要研究如何进行数据采集和信令增强。
AI/ML for Air Interface是面向空口增强在R18设立的项目,其研究重点是协作等级、生命周期管理等空口AI的通用架构以及基于AI的信道状态信息(Channel state information,CSI)增强、波束增强和定位增强等三个用例。
随着AI技术和资源的普及,将会有更多的高价值用例涌现,不断提升移动通信系统的性能。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供传输方法、装置及相关设备进行详细地说明。
参见图4,图4是本申请实施例提供的一种传输方法的流程图,如图4所示,传输方法包括以下步骤:

另外,所述至少一层的信息可以包括一层或多层的信息。层还可以描述为流,或映射层等等。所述至少一层还可以描述为至少一个层或至少一个流或至少一个映射层等等。
一种实施方式中,所述码字信息可以是对媒体接入控制(Medium Access Control,MAC)层传递来的一个TB进行CRC添加、信道编码、速率匹配及加扰等操作后得到的比特流信息。
其中,所述第一设备对码字信息进行层映射处理,得到至少一层的信息,可以包括:第一设备对码字信息进行层映射处理,得到K层的信息,K为正整数。
步骤102、所述第一设备对所述至少一层的信息进行调制处理,得到调制后的信息。
其中,所述第一设备可以采用至少两种调制方式对所述至少一层的信息进行调制处理,得到调制后的信息;或,所述第一设备可以采用同一种调制方式对所述至少一层的信息进行调制处理,得到调制后的信息;本申请实施例对此不进行限定。
可选地,所述调制方式可以用于将所述至少一层的信息对应的比特序列映射成符号序列。
其中,调制方式还可以描述为调制方案或调制策略。
其中,所述调制方式可以是将M个比特调制成N个符号的规则。其中,调制方式的调制阶数可用分数M/N或整数组[M,N]描述。当N=1时退化为相关技术中使用的调制阶数。调制方式的映射规则(或描述为具体映射规则)可通过函数、表格或第二AI单元来实现。该具体映射规则可以是由协议预定义的,或可以是在实际调用该映射规则时由网络侧发送给终端侧的,此时该映射规则的标准格式是协议预定义的。
以函数描述的调制方式的具体映射规则举例:
函数如Y=f(X),X是调制前的比特序列,长度为M,Y是调制后的符号序列(一般为复数序列),长度为N。或者Y的实部和虚部的获取过程分别由Re(Y)=f1(X)和Im(Y)=f2(X)描述。

第二AI单元的输入是调制前的比特序列或对其做预处理后得到的序列,第二AI单元的输出可以直接作为调制后的符号序列或经过后处理(比如实部和虚部的匹配和映射)作为调制后的符号序列。
步骤103、所述第一设备基于所述调制后的信息获得第一数据。
其中,所述第一设备可以对所述调制后的信息进行资源映射处理,得到资源映射处理后的信息;对资源映射处理后的信息进行OFDM调制处理,得到第一数据;或者,第一设备可以对所述调制后的信息进行资源映射处理,得到资源映射处理后的信息;对资源映射处理后的信息进行插入解调参考信号(De-Modulation Reference Signal,DMRS)处理,得到插入DMRS处理后的信息;对插入DMRS处理后的信息进行OFDM调制处理,得到第一数据;等等,本实施例对基于所述调制后的信息获得第一数据的具体实现不进行限定。

需要说明的是,正交幅度调制(Quadrature Amplitude Modulation,QAM)和相移键控(Phase Shift Keying,PSK)调制是现有通信系统中最常用的调制方式。但从理论上,当调制阶数大于4时,这两种并不是最优的调制方式。而且,实际的信号检测性能还跟具体的接收机密切相关。在本申请实施例中,通过AI进行端到端设计,共同优化发送端的调制方式和接收端的接收机算法,进而能够获得更好地传输性能。进一步的,目前的通信系统中,在发送端先做调制,后做层映射,对应的在接收端先做层解映射,后做解调。而在本申请实施例中,在发送端先对信息进行层映射,然后每个层各自做调制,支持在不同层使用不同的调制方式,能够更好地将数据处理和信道质量关联,并且借助于基于AI的信号接收,可以实现更高的数据吞吐量。
本申请实施例对信息在物理层的数据处理流程进行了改进,传统方案中是在发送端先对信息进行调制,后进行层映射,对应的在接收端先进行层解映射,后进行解调,如图5所示。而在本申请实施例中,在发送端先对信息进行层映射,然后每个层各自做调制,如图6所示。相比于传统方案,在本申请实施例中,发送端的不同处理在于:将加扰(scrambling)后的码字信息进行层映射(layer mapping),转换成多层或多流数据,对每个流分别进行调制。不同的流或层可以使用不同的调制方式,所述不同的调制方式包括不同调制阶数的调制方式,或调制阶数相同但映射关系不同的调制方式等。

可选地,所述第一设备对所述至少一层的信息进行调制处理,得到调制后的信息,包括:

可选地,所述至少一层的信息包括第一信息和第二信息,所述第一信息和所述第二信息为不同层的信息,对所述第一信息进行调制处理采用的第一调制方式与对所述第二信息进行调制处理采用的第二调制方式不同。
其中,所述至少一层的信息可以包括多层的信息,第一信息和第二信息可以为该多层的信息中的任意两层的信息。
该实施方式中,所述至少一层的信息包括第一信息和第二信息,所述第一信息和所述第二信息为不同层的信息,对所述第一信息进行调制处理采用的第一调制方式与对所述第二信息进行调制处理采用的第二调制方式不同,这样,对于不同层,支持采用不同的调制方式,能够更好地将数据处理和信道质量关联,针对不同层对应的信道特征采用不同的调制方式对不同层的信息进行处理,能够提高调制效果。
可选地,在所述第一设备为终端,所述第二设备为网络侧设备的情况下,所述方法还包括如下至少一项:

其中,解调方式还可以描述为解调方案或解调策略。
另外,网络侧设备可以向终端发送第三信息以确定上行传输方案。
其中,调制方式与层的关联信息,可以用于指示每个层采用的调制方式。示例地,调制方式与层的关联信息可以用于指示终端在后续的数据传输中需要使用的调制方式与层的关联关系,即哪个层使用什么调制方式。比如第一层使用调制方式1,第二层和第三层使用调制方式2,第四层使用调制方式3。

另外,所述用于指示每个层支持的调制方式的指示信息,可以包括每个层支持的调制方式的标识或版本。所述调制方式的标识或版本可以通过集合的形式表征,或者可以通过列表的形式表征,或者可以通过其他形式表征,本实施例对此不进行限定。
一种实施方式中,所述支持的调制方式可以是指支持的将M个比特调制成N个符号的规则。进一步的,同一个调制阶数下可以有多个调制方式用来支持不同的传输场景。比如同一个调制阶数下终端速度低于30km/h使用一个调制方式,终端速度高于30km/h使用另一个调制方式。以[M,N]的标识方式为例,调制方式集合的举例如下:{[调制阶数为[2,1]的方案1,调制阶数为[4,1]的调制方式1,调制阶数为[4,1]的调制方式2,调制阶数为[8,1]的调制方式1,调制阶数为[8,1]的调制方式2,调制阶数为[8,1]的调制方式3,调制阶数为[8,3]的调制方式1,调制阶数为[8,3]的调制方式2]}。上述集合中每个调制方式均具有一个唯一的标识,且可携带版本号。因此这里上报的内容是每个调制方式的唯一标识+版本号,而并不是该调制方式的具体映射规则。
该实施方式中,在所述第一设备为终端,所述第二设备为网络侧设备的情况下,所述第一设备向所述网络侧设备发送能力信息,从而能够实现终端向网络侧设备进行能力上报,便于网络侧设备根据终端的能力对终端的上行发送或下行接收进行调度。

本申请实施例提出一种在不同层基于不同的调制方式进行数据传输的方案,主要实现了终端关于多层调制和信号接收能力的上报,下行和上行多层传输方案的信令流程的确定,收发端分层信号处理流程的确定。本申请实施例通过在不同层使用不同的调制方式,借助于基于AI的信号接收,可以更好地将数据处理和信道质量关联起来,实现更高的数据吞吐量。
参见图7,图7是本申请实施例提供的一种传输方法的流程图,如图7所示,传输方法包括以下步骤:
步骤201、第二设备接收第一设备发送的第一数据;
步骤202、所述第二设备基于所述第一数据进行目标处理,得到至少一层的解调后的信息;
步骤203、所述第二设备对所述至少一层的解调后的信息进行层解映射处理,得到码字信息。
其中,所述第一数据可以为符号序列。所述解调后的信息可以为比特序列。
其中,所述第二设备基于所述第一数据进行目标处理,得到至少一层的解调后的信息,可以包括:第二设备基于所述第一数据进行目标处理,得到K层的解调后的信息。
其中,可以使用AI单元来实现接收端不同的层的接收操作;或,不使用AI单元来实现接收端的接收操作。在进行目标处理时,所述第二设备可以使用第一AI单元或者可以不使用第一AI单元。以使用第一AI单元为例,所述第二设备基于所述第一数据进行目标处理,得到至少一层的解调后的信息,可以包括:所述第二设备对所述第一数据进行第一处理,获得目标信息,所述第二设备基于至少一个第一AI单元对所述目标信息进行第二处理,得到至少一层的解调后的信息。以不使用第一AI单元为例,所述第二设备可以对第一数据进行解资源映射处理、信道估计处理、均衡处理及解调处理,得到至少一层的解调后的信息。本申请实施例对基于所述第一数据进行目标处理得到至少一层的解调后的信息的具体实现不进行限定。
相比于传统方案,在本申请实施例中,接收端的不同处理在于:将均衡(equalization)或多天线信号检测(multiple antenna signal detection)之后的各层符号信息分别进行解调,得到每个层或每个流上的比特信息,再进行层解映射(layer demapping),不同的流或层可以使用不同的解调方式,所述不同的解调方式包括不同调制阶数的解调方式,或调制阶数相同但映射关系不同的解调方式等。
可选地,所述第二设备基于所述第一数据进行目标处理,得到至少一层的解调后的信息,包括:
所述第二设备对所述第一数据进行第一处理,获得目标信息;
所述第二设备基于至少一个第一AI单元对所述目标信息进行第二处理,得到至少一层的解调后的信息。
其中,所述第二设备基于至少一个第一AI单元对所述目标信息进行第二处理,得到至少一层的解调后的信息可以包括:所述第二设备将所述至少一层均衡处理后的信息一一对应的输入至少一个第一AI单元,所述第二设备基于所述至少一个第一AI单元的输出获得至少一层的解调后的信息;或,所述第二设备将所述至少一层信道估计处理后的信息一一对应的输入至少一个第一AI单元,所述第二设备基于所述至少一个第一AI单元的输出获得至少一层的解调后的信息;或,所述第二设备将所述至少一层解资源映射处理后的信息一一对应的输入至少一个第一AI单元,所述第二设备基于所述至少一个第一AI单元的输出获得至少一层的解调后的信息;等等,本实施例对此不进行限定。
该实施方式中,所述第二设备基于至少一个第一AI单元对所述目标信息进行第二处理,得到至少一层的解调后的信息,这样,通过AI单元来实现接收端不同的层的接收操作,基于AI的信号接收,可以实现更高的数据吞吐量。
可选地,所述第一AI单元用于如下任意一项:
解调处理;
均衡和解调的联合处理;
信道估计、均衡和解调的联合处理。
一种实施方式中,在所述第一AI单元用于解调处理的情况下,第一AI单元的输入关联对接收到的数据信号做完均衡之后的复数信号,第一AI单元的输出是与数据信号对应的比特序列。
一种实施方式中,在所述第一AI单元用于均衡与解调的联合处理(即均衡+解调)的情况下,第一AI单元的输入关联接收到的数据信号和信道的估计量,第一AI单元的输出是与数据信号对应的比特序列。
一种实施方式中,在所述第一AI单元用于信道估计、均衡及解调的联合处理(即信道估计+均衡+解调)的情况下,第一AI单元的输入关联接收到的数据信号、接收到的DMRS信号和发送端发送的DMRS原始信号,第一AI单元的输出是与数据信号对应的比特序列。
另外,所述信道估计、均衡和解调的联合处理,可以包括:无导频传输时的信道估计、均衡及解调的联合处理。
一种实施方式中,在所述第一AI单元用于无导频传输时的信道估计、均衡及解调的联合处理(即无导频传输时的信道估计+均衡+解调)的情况下,第一AI单元的输入关联接收到的数据信号,第一AI单元的输出是与数据信号对应的比特序列。此模式下发送端只发送数据信号,不发送DMRS。
另外,第一AI单元的输入关联接收到的数据信号(或信道的估计量,或接收到的DMRS信号,或发送端发送的DMRS原始信号,或对接收到的数据信号做完均衡之后的复数信号),可以是指将接收到的数据信号(或信道的估计量,或接收到的DMRS信号,或发送端发送的DMRS原始信号,或对接收到的数据信号做完均衡之后的复数信号)直接作为第一AI单元的输入;或,可以是将接收到的数据信号(或信道的估计量,或接收到的DMRS信号,或发送端发送的DMRS原始信号,或对接收到的数据信号做完均衡之后的复数信号)进行处理后的信号作为第一AI单元的输入,例如,将接收到的数据信号的实部和虚部分别取出排列成特定的维度(如向量,矩阵或张量)作为第一AI单元的输入。
需要说明的是,第一AI单元实现不同的功能时其泛化能力是不同的,从实现解调处理的AI单元,实现均衡和解调的联合处理的AI单元,以及实现信道估计、均衡和解调的联合处理的AI单元的泛化性能依次逐渐变差。因此,即使发送端采用相同的调制方式发送数据,不同的接收端也可使用不同的第一AI单元完成数据接收获得比特序列。比如,活动场景变化多的终端可以使用实现解调处理的第一AI单元,活动场景变化少的终端可以使用实现无导频传输时的信道估计、均衡及解调的联合处理的第一AI单元。即使发送端使用相同的调制方式,不同的接收端也可以配置和使用不同的第一AI单元。
可选地,所述目标信息包括至少一层均衡处理后的信息;

另外,所述解调后的信息可以为第一AI单元的输出,或,对第一AI单元的输出进行后处理之后的信息。所述后处理可以是指对第一AI单元的输出做维度调整,比如第一AI单元的输出是个矩阵,则将其按照预设规则调整成一个向量。

一种实施方式中,接收端可以使用第一AI单元实现解调功能,如图8所示。
相比于传统方案,在本申请实施例中,接收端的不同处理在于:将均衡(equalization)或多天线信号检测(multiple antenna signal detection)之后的各层符号信息直接输入到第一AI单元或做预处理后分别输入到第一AI单元,将第一AI单元的输出直接作为每个层或流上的比特信息,或将第一AI单元的输出进行后处理之后作为每个层或流上的比特信息,再进行层解映射(layer demapping),不同的流或层可以使用不同的第一AI单元。所述预处理可以是将各层符号信息的实部和虚部分别取出排列成特定的维度(如向量,矩阵或张量)作为第一AI单元的输入。所述后处理可以是指对第一AI单元的输出做维度调整,比如第一AI单元的输出是个矩阵,则将其按照预设规则调整成一个向量。
