Description

数据处理方法和装置 技术领域
本文涉及但不限于通信领域，尤指一种数据处理方法和装置。
背景技术
长期演进(LTE，Long Term Evolution)是第三代合作伙伴计划(3rd Generation Partnership Project，简称为3GPP)长期演进项目，是近两年来3GPP启动的最大的新技术研发项目，这种以正交频分复用(Orthogonal Frequency Division Multiplexing，简称为OFDM)或频分多址(Frequency Division Multiple Access，简称为FDMA)为核心的技术可以被看做是“准第四代移动通信(4G)”技术。LTE主要的优势是峰值速率高，系统时延小，支持带宽灵活配置。例如：20兆赫兹(MHz)频谱带宽能够提供下行100兆比特每秒(Mbps)、上行50Mbps的峰值速率，用户面内部单向传输时延小于5毫秒(ms)，支持1.25MHz到20MHz带宽的灵活配置，还可以使用载波聚合技术，进一步提高小区容量。
在研究过程中发现，基于LTE实现集群通信是近几年开始兴起的一种技术，已经制定行业标准。标准中组呼共享承载没有对应上行承载，在共享承载上传输的内容终端能否正确接收，是没有反馈的，从而没有混合自动重传请求(Hybrid Automatic Repeat reQuest，简称为HARQ)重传，这样对关键内容的传输无法保证终端能够正确接收而出现问题。
针对相关技术中组呼共享承载无法保证传输信息的正确率的问题，目前尚未提出有效的解决方案。

本发明的实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种数据处理方法，图1是根据本发明实施例的数据处理方法的流程图一，如图1所示，该流程包括如下步骤：
步骤S102，基站识别待调度数据中是否携带预设信息，其中，预设信息包括以下至少之一：控制信息、用于解码其他数据的参考信息；
步骤S104，在识别到待调度数据中携带预设信息的情况下，基站设置待调度数据的重传次数；
步骤S106，基站按照重传次数在连续的下行子帧上重传待调度数据。
通过上述步骤，基站识别待调度数据中是否携带预设信息，为携带有预设信息的待调度数据设置重传次数，并按照重传次数在连续的下行子帧上重传待调度数据，在组呼共享承载没有上行承载，无法对信息是否正确接收进行反馈的情况下，自动为用户设备重传信息。可见，采用上述步骤，提高了组呼共享承载中传输信息的正确率。
可选地，在基站通过组呼共享承载向用户设备发送的信息中，有些信息是相对更为重要的，例如：控制信息、用于解码其他数据的参考信息，在上述信息无法正确解码的情况下，将导致命令无法被正确执行或者相关数据无法被正确解码，从而影响了系统的稳定性，因此，在上述步骤S102中，基站识别待调度数据中的预设信息包括但不限于以下至少之一：控制信息、用于解码其他数据的参考信息。
可选地，在视频数据的传输过程中，关键帧是用于解码中间帧的参考信息，在上述步骤S102中，关键帧可以被基站识别为上述预设信息，并为携带有关键帧的待调度数据设置重传次数进行重传处理，提高关键帧信息的解码成功率，从而保证中间帧信息的解码成功率。
可选地，在上述步骤S104中，基站可以根据以下至少之一设置待调度数据的重传次数：待调度数据的调制解调方式、信道质量、信号强度，其中，待调度数据的调制解调方式的信道编码率越高，则设置重传次数越大，传输数据的信道质量越差，则设置重传次数越大，信号强度越低，则设置重传次数越大。通过上述方法，根据不同的条件设置不同的重传次数，在提高信息传输的正确率的同时，也可以节省资源。
可选地，在上述步骤S104中，基站可以根据待调度数据的调制解调方式设置重传次数，例如：基站确定待调度数据的调制解调方式；基站根据调制解调方式，设置重传次数，其中，调制解调方式的信道编码率越高，则设置重传次数越大。调制解调方式的信道编码率越高，用户设备在解码的过程中难度越大，出错率也就越高，为信道编码率较高的调制解调方式设置较大的重传次数，可以提高用户设备的解码成功率，从而提高了信息传输的正确率。
可选地，组呼共享承载常用的调制解调方式包括正交相移键控(QPSK，Quadrature Phase Shift Keyin)、16正交幅度调制(QAM，Quadrature Amplitude Modulation)和64QAM等，其中，这三种调试解调方式的信道编码率依次增高，为了保证这三种调制解调方式都能达到一定的信息传输正确率，基站为这三种调试解调方式设置的重传次数依次变大，例如：在上述步骤S104中，根据待调度数据的调制解调方式设置重传次数包括以下至少之一：基站确定待调度数据的调制解调方式为QPSK，则设置重传次数为第一预设值；基站 确定待调度数据的调制解调方式为16QAM，则设置重传次数为第二预设值，其中，第二预设值大于第一预设值；基站确定待调度数据的调制解调方式为64QAM，则设置重传次数为第三预设值，其中，第三预设值大于第二预设值。
可选地，在上述步骤S102之后，在识别到待调度数据中未携带预设信息的情况下，为了减少资源的浪费，更加合理的分配资源，基站可以直接将待调度数据作为新传数据进行发送，而不必进行重传。
可选地，在上述步骤S106中，基站按照所述重传次数在连续的下行子帧上重传所述待调度数据之前还包括：基站还可以将待调度数据中的预设信息标识设置为预设值，预设值用于指示待调度数据中携带有预设信息。通过上述步骤，可以使用户设备通过识别预设信息标识是否设置为预设值判断待调度数据中是否携带有预设信息。
在本实施例中还提供了一种数据处理方法，图2是根据本发明实施例的数据处理方法的流程图二，如图2所示，该流程包括如下步骤：
步骤S202，用户设备从连续的多个下行子帧接收携带有预设信息的多份待调度数据，其中，预设信息包括以下至少之一：控制信息、用于解码其他数据的参考信息；
步骤S204，用户设备对多份待调度数据进行合并解调。
也就是说，用户设备接收到一个下行子帧后，进行解调，如果第一次解调成功，则对解调得到的数据进行处理；
如果第二次或第二次以上解调成功，且解调到的数据与上一次解调得到的数据相同，则不对解调得到的数据进行处理；
如果第二次或第二次以上解调成功，且解调到的数据与上一次解调得到的数据不相同，则对解调得到的数据进行处理；
如果解调失败，则继续解调下一个下行子帧。
通过上述步骤，用户设备接收到多份携带有预设信息的待调度数据，并对多份待调度数据进行合并解调，提高了预设信息的解码成功率，从而也提高了信息传输的成功率。可见，采用上述步骤，提高了组呼共享承载中传输信息的正确率。
可选地，在上述步骤S202中，参考信息包括：关键帧。用户设备可以接收到多份携带有关键帧的待调度数据，并对多份携带有关键帧的待调度数据进行合并解调，提高了关键帧信息的解码成功率，从而保证了中间帧信息的解码成功率。

为了使本发明实施例的描述更加清楚，下面结合可选实施例进行描述和说明。
本发明可选实施例通过分析相关协议的实现方法，提出了一种集群共享信道选择性HARQ重传方法，在相关协议的规定下，组呼共享承载没有对应上行承载，在共享承载上传输的内容终端能否正确接收，是没有反馈的，从而没有HARQ重传，这样对关键内容的传输无法保证终端能够正确接收而出 现各种问题。本发明可选实施例提出的一种集群共享信道选择性HARQ重传方法，提高了终端对关键内容的正确接收概率。
本发明可选实施例提供的集群共享信道选择性HARQ重传方法包括如下步骤：
步骤1，基站识别需要调度的数据(相当于上述待调度数据)中是否包含关键信息(相当于上述预设信息)，如果是，则置位关键信息标志(相当于上述预设信息标识)为1，如果不是，则置位关键信息标志为0；
步骤2，基站为本次调度分配资源，确定调制解调方式；
步骤3，基站根据关键信息标志位，和调制解调方式确定重传次数。如果重传次数大于1，在连续的下行子帧进行重传；
步骤4，终端(相当于上述用户设备)在下行子帧连续接收数据，对多份数据进行合并解调。
采用本发明可选实施例所述方法，基站根据是否包含关键信息和调制解调方式确定待调度数据的重传次数，用户设备对接收到的多份待调度数据进行合并解调，提高了终端对关键内容的正确接收概率。
下面结合附图对本发明可选实施例进行说明。
本发明可选实施例为了提高终端对关键信息的正确接收率，基站根据调度的内容和采用的调制解调方式，进行相应HARQ重传。
图8是根据本发明可选实施例的集群共享信道选择性HARQ重传方法的流程图一，如图8所示，该流程包括如下步骤：
步骤S802，基站识别需要调度的数据(相当于上述待调度数据)中不包括关键信息(相当于上述预设信息)，置关键信息标志位(相当于上述预设信息标识)为0；
步骤S804，基站为本次调度分配资源，确定调制解调方式；
步骤S806，由于基站本次调度的内容为非关键信息，不进行重传，仅调度新传数据；
步骤S808，终端(相当于上述用户设备)接收新传数据。
通过上述步骤，基站将不包括关键信息的待调度数据作为新传数据发送给终端，一方面不会影响信息传输的成功率，另一方面节省了信息资源。
图9是根据本发明可选实施例的集群共享信道选择性HARQ重传方法的流程图二，如图9所示，该流程包括如下步骤：
步骤S902，基站识别需要调度的数据(相当于上述待调度数据)中包括关键信息(相当于上述预设信息)，置关键信息标志位(相当于上述预设信息标识)为1；
步骤S904，基站确定本次调度的调制解调方式为QPSK；
步骤S906，由于基站本次调度的内容为关键信息，且调制解调方式为QPSK，确定重传次数为1次；
步骤S908，基站按照确定的重传次数在连续的下行子帧进行重传；
步骤S910，终端(相当于上述用户设备)对连续两个下行子帧接收的数据进行合并解调。
通过上述步骤，基站将携带关键信息并且调制解调方式为QPSK的待调度数据的重传1次，终端对接收到的两份待调度数据进行合并解调，提高了终端对关键内容的正确接收概率。
图10是根据本发明可选实施例的集群共享信道选择性HARQ重传方法的流程图三，如图10所示，该流程包括如下步骤：
步骤S1002，基站识别需要调度的数据(相当于上述待调度数据)中包括关键信息(相当于上述预设信息)，置关键信息标志位(相当于上述预设信息标识)为1；
步骤S1004，基站确定本次调度的调制解调方式为16QAM；
步骤S1006，由于基站本次调度的内容为关键信息，且调制解调方式为16QAM，确定重传次数为2次；
步骤S1008，基站按照确定的重传次数在连续的下行子帧进行重传；
步骤S1010，终端(相当于上述用户设备)对连续三个下行子帧接收的数据进行合并解调。
通过上述步骤，由于16QAM的信道编码率高于QPSK，为了保证信息的正确解码率，基站将携带关键信息并且调制解调方式为16QAM的待调度数据的重传2次，终端对接收到的三份待调度数据进行合并解调，提高了终端对关键内容的正确接收概率。
图11是根据本发明可选实施例的集群共享信道选择性HARQ重传方法的流程图四，如图11所示，该流程包括如下步骤：
步骤S1102，基站识别需要调度的数据(相当于上述待调度数据)中包括关键信息(相当于上述预设信息)，置关键信息标志位(相当于上述预设信息标识)为1；
步骤S1104，基站确定本次调度的调制解调方式为64QAM；
步骤S1106，由于基站本次调度的内容为关键信息，且调制解调方式为64QAM，确定重传次数为3次；
步骤S1108，基站按照确定的重传次数在连续的下行子帧进行重传；
步骤S1110，终端(相当于上述用户设备)对连续四个下行子帧接收的数据进行合并解调。
通过上述步骤，由于64QAM的信道编码率高于16QAM，为了保证信息的正确解码率，基站将携带关键信息并且调制解调方式为64QAM的待调度数据的重传3次，终端对接收到的四份待调度数据进行合并解调，提高了终端对关键内容的正确接收概率。
综上所述，通过本发明的上述实施例和可选实施例，新增了一种数据处理模式，本发明可选实施例提出了一种集群共享信道选择性HARQ重传方法，在终端没有反馈的情况下，根据基站调度的内容和调度使用的调制解调方式，选择性进行HARQ重传，提高终端对关键内容的正确接收概率。

本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储 介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储与存储器中的程序/指令来实现其相应功能。本发明不限于任何特定形式的硬件和软件的结合。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
