通常，星座图包括以特定配置排布的多个星座点，星座图表示数字数据到载波信号或载波的映射，反之亦然。
在无线通信系统中，收发设备间需要通过星座图对传输数据进行相应处理，以保证收发信息的准确性。通常，发送端设备会根据星座图对信息进行编码和调制，并将编码和调制后的信息发送给接收端设备，接收端设备再根据星座图对接收到的信息进行译码和解调，以完成数据的传输。

具体实施方式
以下，首先对本申请中的接收端设备和发送端设备进行解释说明，以便于本领域技术人员理解。
在本申请中，接收端设备可以为终端设备，则发送端设备则为网络设备，或者，接收端设备为网络设备时，发送端设备则可以为终端设备，当然，接收端设备和发送端设备还可以为其他需要根据星座图进行数据的调制或者解调的设备。
其中，1)终端设备，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(wireless local area networks，WLAN)中的站点(station，ST)，可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统，例如，第五代通信(fifth-generation，5G)网络中的终端设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端设备，新空口(new radio，NR)通信系统中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
2)网络设备，可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(access point，AP)，GSM或CDMA中的基站(base transceiver station，BTS)，也可以是WCDMA中的基站(nodeB，NB)，还可以是LTE中的演进型基站(evolutional node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，或NR系统中的新一代基站(new generation node B,gNodeB)等。
本领域技术人员可以理解，本申请实施例提供的数据的传输方法，可以应用于发送端设备通过星座图对数据进行调制后发送，以及接收端设备通过星座图对接收到的数据进行解调的通信系统中。图1为通信系统的架构示意图，如图1所示，该系统包括终端设备10和网络设备20，其中，终端设备10例如可以为UE，网络设备20可以为基站，其中，接收端设备为终端设备10时，发送端设备则为网络设备20，或者，接收端设备为网络设备20时，发送端设备则可以为终端设备10。
在现有的通信系统中，通常第三代合作伙伴计划(3rd generation partnership project；3GPP)协议根据信道质量情况规定唯一的星座图，应用于发送端设备和接收端设备。发送端设备会通过协议规定的标准星座图对待发送的数据进行调制，并将调制后的数据发送给接收端设备，接收端设备将通过协议规定的标准星座图对接收到的数据进行 解调。然而，由于发送端设备发送的数据会经历各种失真和噪声干扰，如器件的非线性、信道、噪声和同步误差等，接收端设备通过上述标准星座图对数据进行解调时，会引起传输差错，造成通信性能较低。
本申请实施例考虑到这些情况，提出一种数据的传输方法，该方法中接收端设备接收发送端设备发送的训练数据，该训练数据为发送端设备和接收端设备已知的数据，且该训练数据包括同步信号、参考信号和专用用户面训练数据中的至少一个，并根据接收到的失真的训练数据，确定数据的星座图的失真模式，然后根据失真模式确定用于接收数据的星座图的接收模式，再根据确定的星座图的接收模式从发送端设备接收数据。由于接收端设备会根据发送端设备发送的失真的训练数据，确定出数据的星座图的失真模式，并根据该失真模式确定接收数据的星座图的接收模式，从而可以根据确定出的星座图的接收模式从发送端设备接收数据，这样，接收端设备将可以根据不同的失真模式，采用不同的星座图接收数据，从而可以减少传输差错，提高数据传输的准确性，由此可以提高通信性能。
图2为本申请数据的传输方法的一种信令流程图。在上述图1所示系统架构的基础上，如图2所示，本实施例的方法可以包括：
步骤201、发送端设备向接收端设备发送训练数据。
其中，训练数据为发送端设备和接收端设备已知的数据，该训练数据包括同步信号、参考信号和专用用户面训练数据中的至少一个。
在本步骤中，训练数据为发送端设备和接收端设备已知的数据，其中，该训练数据可以包括用户面数据和控制面数据，其中，控制面数据可以包括同步信号和/或参考信号，专用用户面训练数据例如可以包括双方约定的已知数据。
步骤202、接收端设备根据接收到的失真的训练数据，确定数据的星座图的失真模式。
在本步骤中，图3a-图3c为失真模式的示意图，如图3a-图3c所示，发送端设备向接收端设备发送训练数据的过程中，该训练数据会经历各种失真和噪声干扰，如器件的非线性、信道特性、噪声以及同步误差等，因此，接收端设备接收到的将为失真的训练数据。其中，信道特性包括时域特性、空域特性、频域特性和功率域特性。接收端设备在接收到失真的训练数据时，将根据该失真的训练数据，确定数据的星座图的失真模式，如图3a中，该失真模式中包括有非均匀分布的噪声，如图3b中，该失真模式中数据向某一方向压缩，如图3c中，该失真模式中数据绕中心点旋转。
在一种可能的实现方式中，接收端设备根据接收到的失真的训练数据，确定数据的星座图的失真模式，包括接收端设备通过对失真的训练数据进行识别和分类，并确定失真的训练数据的类别。
具体的，由于器件的非线性、信道、噪声以及同步误差等原因均会引起数据的失真，因此，在确定失真模式时，可以通过对失真的训练数据进行识别和分类，以确定引起该训练数据失真的原因的类别。
另外，在实际应用中，接收端设备可以通过离线训练方式或在线训练方式发现器件的非线性、信道、噪声以及同步误差等误差源对星座图的影响。下面，将分别对如何通过离线训练方式或在线训练方式对失真的训练数据进行识别和分类，并确定失真 的训练数据的类别所对应的失真模式进行详细介绍。
图4为离线训练方式的流程示意图，如图4所示，在接收端设备中包括有机器学习模块，该机器学习模块包括输入层、输出层和1个或多个隐含层，各层间的神经元可以全连接或部分连接。其中，机器学习模块对失真的训练数据进行识别和分类时所采用的学习算法可以包括：监督学习算法(Regression model，K-nearest neighbor,support vector machines，Bayesian learning)、非监督学习算法(K-means，Principal component analysis，independent component analysis)和加强学习算法(Markov decision processes,partially observable Markov decision process,Q-learning)。具体说，一种机器学习模块的实现可以包括6层，其中4个隐含层，每层分别有16,256,128,64,32和8个神经元，各神经元全连接。
继续参照图4所示，S为输入、
Figure PCTCN2018076890-appb-000001
为输出，将失真的训练数据输入到机器学习模块中，经过发送端、信道和接收端，将输出失真模式和优化的星座图分布。
图5为在线训练方式的流程示意图，如图5所示，其中，发送端设备和接收端设备之间可以通过发送已知的训练数据，并进行反馈，以使误差ε最小，从而获得失真模式和优化的星座图分布。
步骤203、接收端设备根据失真模式确定用于接收数据的星座图的接收模式。
在本实施例中，接收端设备中预先存储有各种失真模式所对应的星座图的接收模式，当接收端设备在确定出数据的星座图的失真模式之后，将根据失真模式与星座图的接收模式之间的对应关系，确定采用何种星座图接收数据。
图6a为第三星座图的示意图，图6b-图6c为优化的星座图的示意图，其中，图6a中所示的第三星座图为协议中规定的标准星座图，即失真或干扰小于预设阈值的失真模式对应的星座图，而图6b-图6c中所示的星座图，是通过图4所示的离线训练方式或者图5所示的在线训练方式，对接收到的失真的训练数据进行识别和分类之后，在确定出多种失真模式的同时，对失真模式对应的星座图进行优化后获得的不同星座图。
值得注意的是，由于优化后的星座图是发送端设备或接收端对失真模式对应的星座图进行相应调整之后获得的星座图，因此，在实际应用中，发送端设备在采用优化后的星座图进行数据的调制时，接收端设备可以采用相同的优化后的星座图，进行数据的解调。
步骤204、接收端设备根据确定的星座图的接收模式从发送端设备接收数据。
在本步骤中，接收端设备在确定出星座图的接收模式之后，将根据确定出的接收模式，从发送端设备接收数据，其中，接收端设备从发送端设备接收到的数据例如可以包括物理上行共享信道(physical uplink shared channel；PUSCH)和物理下行共享信道(Physical Downlink Shared Channel；PDSCH)。
在实际应用中，发送端设备在根据星座图对待发送的数据进行调制，以及接收端设备在对接收到的数据进行解调时，可以包括如下几种情况：发送端设备根据现有协议规定第三星座图对待发送的数据进行调制，而接收端设备根据非标准星座图对接收到的数据进行解调，或者，发送端设备根据非标准星座图对待发送的数据进行调制，而接收端设备根据第三星座图对接收到的数据进行解调，或者，发送端设备根据非标 准星座图对待发送的数据进行调制，而接收端设备根据非标准星座图对接收到的数据进行解调。其中，第三星座图为现有协议中规定的标准星座图，非标准星座图为通过图4或图5中所示的机器学习模块学习得到的星座图。
下面，将对上述几种不同的情况进行详细说明。
(1)发送端设备根据第三星座图对待发送的数据进行调制，而接收端设备根据非标准星座图对接收到的数据进行解调的情形
对于这种情况，接收端设备可以根据预先存储的失真模式与星座图之间的对应关系，确定与失真模式对应的第一星座图，这样，接收端设备在根据确定的星座图的接收模式从发送端设备接收数据，可以包括根据确定出的第一星座图对接收到的数据进行解调。
具体的，若接收端设备根据接收到的失真的训练数据，确定出数据的星座图的失真模式，则将根据预先存储的此失真模式与星座图之间的对应关系，确定出与此失真模式对应的第一星座图。例如：若确定出的失真模式为图3a中所示的模式，则接收端设备将根据预先存储的失真模式与星座图之间的对应关系，确定与图3a中所示的失真模式对应的第一星座图。这样，当发送端设备根据第三星座图对待发送的数据进行调制，并发送给接收端设备的过程中，可能会由于发送端设备或接收端设备的非线性特征、信道、噪声以及同步误差等原因，造成发送端设备所发送的数据的失真。接收端设备在接收数据时，将会采用确定出的第一星座图对接收到的数据进行解调，这样，将会保证接收端设备接收的数据的正确性，从而可以提高通信性能。
在上述方式中，由于发送端设备根据第三星座图对待发送的数据进行调制，而接收端设备根据第一星座图对接收到的数据进行解调，这样由于改变了接收端设备的星座图，且接收端设备的结构和数据接收的流程均不变，从而可以提高数据传输准确性。
(2)发送端设备根据非标准星座图对待发送的数据进行调制，而接收端设备根据第三星座图对接收到的数据进行解调的情形
对于这种情况，在一种可能的实现方式中，接收端设备将会根据失真模式确定用于接收数据的星座图的接收模式为第三星座图，且接收端设备根据确定的星座图的接收模式从发送端设备接收数据，可以包括将失真模式发送给发送端设备，该失真模式用于指示发送端设备确定第二星座图，接收端设备从发送端设备接收数据，该数据根据第二星座图调制得到，接收端设备根据第三星座图对接收到的数据进行解调。
具体的，若接收端设备采用第三星座图对接收到的数据进行解调，则发送端设备则需要根据失真模式，采用非标准星座图对待发送的数据进行调制。在具体的实现过程中，接收端设备在根据接收到的失真的训练数据，确定出数据的星座图的失真模式后，则将该失真模式发送给发送端设备。由于在发送端设备本地也存储有失真模式与星座图之间的对应关系，发送端设备可以根据接收到的失真模式与上述的对应关系，确定出与该失真模式对应的第二星座图，并根据确定出的第二星座图对待发送数据进行调制，从而将调制后的数据发送给接收端设备。其中，发送端设备根据数据的星座图的失真模式，确定星座图的接收模式的方式，与接收端设备根据数据的星座图的失真模式，确定星座图的接收模式的方式类似，此处不再赘述。
举例来说，继续参照图3a所示，若接收端设备确定出用于接收数据的星座图的接 收模式为第三星座图，且接收端设备在确定出数据的星座图的失真模式后，会将该失真模式发送给发送端设备，发送端设备根据预先存储的失真模式与星座图之间的对应关系，确定出与此失真模式对应的第二星座图，如确定出与图3a所示的失真模式对应的第二星座图，这样，发送端设备为了对抗同步误差，则会对确定出的第二星座图进行调整，并根据调整后的第二星座图对待发送数据进行调制，如由于图5e所示的失真模式中各信号在失真会整体下移，则发送端设备对图5e所示的失真模式对应的第二星座图进行调整时，会将该第二星座图中的各信号整体上移后，再对待发送数据进行调制，这样，对于接收端设备来说，其根据第三星座图即可对数据进行解码。
值得注意的是，本申请实施例中对发送端设备如何对第二星座图进行调整的方式不做具体限制，只要能保证接收端设备能够根据第三星座图正确的解调数据即可。
在另一种可能的实现方式中，接收端设备根据失真模式确定用于接收数据的星座图的接收模式为第三星座图，则接收端设备根据确定的星座图的接收模式从发送端设备接收数据，包括根据预先存储的失真模式与星座图之间的对应关系，确定与失真模式对应的第一星座图，接收端设备将第一星座图发送给发送端设备，接收端设备从发送端设备接收数据，该数据根据第一星座图调制得到，接收端设备根据第三星座图对接收到的数据进行解调。
具体的，本方式与上述方式的不同之处在于，接收端设备在确定出数据的星座图的失真模式之后，并不是直接将失真模式发送给发送端设备，而是根据本地预先存储的失真模式与星座图之间的对应关系，确定出与失真模式对应的第一星座图，并将该第一星座图发送给发送端设备。另外，由于接收端设备用于接收数据的星座图的接收模式为第三星座图，因此，发送端设备为了对抗失真，则会对第一星座图进行调整，并根据调整后的第一星座图对待发送数据进行调制，以保证接收端设备根据第三星座图能够正确的解调到数据。值得注意的是，本申请实施例中对发送端设备如何对第一星座图进行调整的方式不做具体限制，只要能保证接收端设备能够根据第三星座图正确的解调数据即可。
在上述方式中，由于发送端设备根据非标准星座图对待发送的数据进行调制，而接收端设备根据第三星座图对接收到的数据进行解调，这样由于只改变发送端设备的星座图，且发送端设备的结构和数据发送的流程均不变，从而提高数据传输准确性。
(3)发送端设备根据优化的非标准星座图对待发送的数据进行调制，而接收端设备根据优化的非标准星座图对接收到的数据进行解调的情形
对于这种情况，在一种可能的实现方式中，接收端设备在根据预先存储的失真模式与星座图之间的对应关系，确定出与失真模式对应的第一星座图之后，会将第一星座图发送给发送端设备，该接收端设备从发送端设备接收数据，该数据根据第一星座图调制得到，接收端设备根据第一星座图对接收到的数据进行解调。
具体的，接收端设备在根据失真的训练数据，确定出数据的星座图的失真模式后，将根据预先存储的失真模式与星座图之间的对应关系，确定出与失真模式对应的第一星座图，并将该第一星座图发送给发送端设备。由于接收端设备是根据第一星座图对接收到的数据进行解调，这样，发送端设备为了对抗失真，则会对第一星座图进行调整，并根据调整后的第一星座图对待发送数据进行调制，以保证接收端设备根据第一 星座图能够正确的解调到数据，在这种情况下，发送端设备对待发送的数据进行调制时使用的星座图与接收端设备对接收到的数据进行解调时使用的星座图可能不同。值得注意的是，本申请实施例中对发送端设备如何对第一星座图进行调整的方式不做具体限制，只要能保证接收端设备能够根据第一星座图正确的解调数据即可。
需要进行说明的是，若接收端设备根据失真模式确定出的第一星座图为如图6a-图6c中所示的优化后的星座图，即确定出的第一星座图为已经根据失真模式对星座图进行调整之后的星座图，此时，发送端设备可以根据确定出的第一星座图对待发送数据进行调制，接收端设备可以根据相同的第一星座图对接收到的数据进行解调。
在另一种可能的实现方式中，接收端设备根据失真模式确定用于接收数据的星座图的接收模式为第二星座图，则接收端设备根据确定的星座图的接收模式从所述发送端设备接收数据，可以包括：接收端设备将失真模式发送给发送端设备，该失真模式用于指示发送端设备确定第二星座图，接收端设备从发送端设备接收数据，该数据根据第二星座图调制得到，接收端设备根据第二星座图对接收到的数据进行解调。
具体的，本方式与上述方式的不同之处在于，接收端设备在确定出数据的星座图的失真模式之后，无需确定与该失真模式对应的星座图的接收模式，而是直接将该失真模式发送给发送端设备，由发送端设备根据预先存储的失真模式与星座图之间的对应关系，确定与失真模式对应的第二星座图。另外，由于接收端设备用于接收数据的星座图的接收模式为第二星座图，因此，发送端设备为了对抗失真，则会对第二星座图进行调整，并根据调整后的第二星座图对待发送数据进行调制，以保证接收端设备根据第二星座图能够正确的解调到数据，在这种情况下，发送端设备对待发送的数据进行调制时使用的星座图与接收端设备对接收到的数据进行解调时使用的星座图可能不同。值得注意的是，本申请实施例中对发送端设备如何对第二星座图进行调整的方式不做具体限制，只要能保证接收端设备能够根据第二星座图正确的解调数据即可。
需要进行说明的是，若发送端设备根据失真模式确定出的第二星座图为如图6a-图6c中所示的优化后的星座图，即确定出的第二星座图为已经根据失真模式对星座图进行调整之后的星座图，此时，发送端设备可以根据确定出的第二星座图对待发送数据进行调制，接收端设备可以根据相同的第二星座图对接收到的数据进行解调。
值得注意的是，除了第三星座图之外，其他的非标准星座图均是在发送端设备和接收端设备的单播通信中使用。
在本实施例中，发送端设备和接收端设备通过识别失真模式，并针对失真模式选择对应的星座图，从而发送端设备根据选择的星座图对待发送的数据进行调制，接收端设备根据选择的星座图对待发送的数据进行调制，从而可以提高数据传输的准确性，提高通信性能。
进一步地，当发送端设备采用非标准星座图，即第一星座图或第二星座图进行数据的调制时，发送端设备的结构和调制的流程均不发生改变，由此可以使得该方法的实现方式更加简单。同样的，当接收端设备采用非标准星座图，即第一星座图或第二星座图进行数据的解调时，接收端设备的结构和解调的流程均不发生改变，也可以使得该方法的实现方式更加简单。
本申请实施例提供的数据的传输方法，该方法中接收端设备接收发送端设备发送 的训练数据，该训练数据为发送端设备和接收端设备已知的数据，且该训练数据包括同步信号、参考信号和专用用户面训练数据中的至少一个，并根据接收到的失真的训练数据，确定数据的星座图的失真模式，然后根据失真模式确定用于接收数据的星座图的接收模式，再根据确定的星座图的接收模式从发送端设备接收数据。由于接收端设备会根据发送端设备发送的失真的训练数据，确定出数据的星座图的失真模式，并根据该失真模式确定接收数据的星座图的接收模式，从而可以根据确定出的星座图的接收模式从发送端设备接收数据，这样，接收端设备将可以根据不同的失真模式，采用不同的星座图接收数据，从而可以避免传输差错，提高数据传输的准确性，由此可以提高通信性能。
