Description

一种数据传输方法、设备及***
本申请要求于2018年06月19日提交中国专利局、申请号为201810629605.5、申请名称为“一种数据传输方法、设备及***”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信技术领域，尤其涉及一种数据传输方法、设备及***。
背景技术
目前，第五代无线通信(5-Generation，5G)***共有64个逻辑信道标识(logical channel identify，LCID)。对于下行数据传输，下行逻辑信道占用了32个LCID(称为legacy LCID)，下行媒体访问控制(media access control，MAC)控制单元占用了17个LCID，其余15个LCID为预留LCID。对于上行数据传输，上行逻辑信道占用了32个LCID，上行MAC控制单元占用了10个LCID，其余22个LCID为预留LCID。
为提高数据传输的可靠性，5G新空口(new radio，NR)***引入了分组数据汇聚协议(packet data convergence protocol，PDCP)包复制(packet duplication)功能。即对于无线承载(包括数据无线承载(data radio bearer，DRB)和信令无线承载(signal radio bearer，SRB))，网络设备可以为这些无线承载配置PDCP包复制功能。具体的，一个无线承载传输的数据在PDCP层经PDCP实体复制后，其原始数据和复制数据分别传输到两个不同的无线链路控制(radio link control，RLC)实体。在载波聚合(carrier aggregation，CA)场景中，这两个RLC实体在同一个小区组，且对应不同的逻辑信道，而不同的逻辑信道具有不同的LCID。
但是，根据目前协议，在最差的情况下(支持8个CA DRB duplication和2个CA SRB duplication)，legacy LCID最多只能支持用户设备(User Equipment，UE)与网络设备之间建立19个DRB，因此随着UE业务需求的提升，如果需要支持UE与网络设备之间建立更多的DRB，那么上述预留LCID的数量可能无法满足扩展需求，从而导致不能提供更好的服务质量。
发明内容

第四方面，本发明实施例提供了一种接入网设备，该接入网设备包括发送模块和接收模块。发送模块，用于向UE发送第一标识，该第一标识用于指示逻辑信道或者调度第一传输信道，该第一标识所在的域包括N个比特位；若该第一标识用于指示逻辑信道，则N为大于6的整数；或者，若该第一标识用于调度第一传输信道，则N为大于16的整数；接收模块，用于在该第一标识指示的逻辑信道或者该第一标识调度的第一传输信道上接收UE发送的第一数据。
第五方面，本发明实施例提供了一种UE，包括处理器、存储器及存储在该存储器上并可在该处理器上运行的计算机程序，该计算机程序被该处理器执行时实现上述第一方面提供的数据传输方法的步骤。
第六方面，本发明实施例提供了一种接入网设备，包括处理器、存储器及存储在该存储器上并可在该处理器上运行的计算机程序，该计算机程序被该处理器执行时实现上述第二方面提供的数据传输方法的步骤。
第七方面，本发明实施例提供了一种通信***，该通信***包括上述第三方面中的UE，以及上述第四方面中的接入网设备。或者，该通信***包括上述第五方面中的UE，以及上述第六方面中的接入网设备。
第八方面，本发明实施例提供了一种计算机可读存储介质，该计算机可读存储介质上存储计算机程序，该计算机程序被处理器执行时实现上述第一方面或者第二方面中的数据传输方法的步骤。
在本发明实施例中，可以获取第一标识(该第一标识用于指示逻辑信道或者调度第一传输信道，该第一标识所在的域包括N个比特位；若该第一标识用于指示逻辑信道，则N为大于6的整数；或者，若该第一标识用于调度第一传输信道，则N为大于16的整数)，以及在该第一标识指示的该逻辑信道或者该第一标识调度的该第一传输信道上发送第一数据。通过该方案，一方面，与现有技术逻辑信道标识所在的域包括6个比特位相比，由于本发明实施例提供的第一标识所在的域包括的比特位的数量大于6，因此本发明实施例扩展了用于指示逻辑信道的标识所在的域的比特数，如此可以支持UE与接入网设备之间建立更多的无线承载。另一方面，与现有技术的小区无线网络临时标识所在的域包括16个比特位相比，由于本发明实施例提供的第一标识所在的域包括的比特位的数量大于16，因此本发明实施例扩展了用于调度传输信道的标 识所在的域的比特数，如此接入网设备可以为UE调度更多的传输信道，从而可以支持UE与接入网设备之间建立更多的无线承载。即本发明实施例中，由于可以支持UE与接入网设备之间建立更多的无线承载，因此可以满足日益增长的UE的业务需求，并提供更好的服务质量。

在本发明实施例的描述中，除非另有说明，“多个”的含义是指两个或者两个以上，例如，多个处理单元是指两个或者两个以上的处理单元等。
本发明实施例提供一种数据传输方法、设备及***，可以获取第一标识(该第一标识用于指示逻辑信道或者调度第一传输信道，该第一标识所在的域包括N个比特位；若该第一标识用于指示逻辑信道，则N为大于6的整数；或者，若该第一标识用于调度第一传输信道，则N为大于16的整数)，以及在该第一标识指示的该逻辑信道或者该第一标识调度的该第一传输信道上发送第一数据。通过该方案，一方面，与现有技术逻辑信道标识所 在的域包括6个比特位相比，由于本发明实施例提供的第一标识所在的域包括的比特位的数量大于6，因此本发明实施例扩展了用于指示逻辑信道的标识所在的域的比特数，如此可以支持UE与接入网设备之间建立更多的无线承载。另一方面，与现有技术的小区无线网络临时标识所在的域包括16个比特位相比，由于本发明实施例提供的第一标识所在的域包括的比特位的数量大于16，因此本发明实施例扩展了用于调度传输信道的标识所在的域的比特数，如此接入网设备可以为UE调度更多的传输信道，从而可以支持UE与接入网设备之间建立更多的无线承载。即本发明实施例中，由于可以支持UE与接入网设备之间建立更多的无线承载，因此可以满足日益增长的UE的业务需求，并提供更好的服务质量。
本发明实施例提供的数据传输方法、设备及***，可以应用于通信***中。例如在第一标识为LCID时，具体可以应用于基于该通信***，UE与网络设备之间传输数据的过程中。
示例性的，图1示出了本发明实施例提供的一种通信***的架构示意图。如图1所示，该通信***可以包括UE 01和接入网设备02。其中，UE 01与接入网设备02之间可以建立连接。
需要说明的是，本发明实施例中，上述如图1所示的UE 01和接入网设备02之间可以是无线连接。
UE是一种向用户提供语音和/或数据连通性的设备，具有有线/无线连接功能的手持式设备，或连接到无线调制解调器的其他处理设备。UE可以经过无线接入网(Radio Access Network，RAN)与一个或多个核心网设备进行通信。UE可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与RAN交换语言和/或数据，例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。UE也可以称为用户代理(User Agent)或者终端设备等。

下面结合各个附图，通过具体的实施例及其应用场景对本发明实施例提供的数据传输方法、设备及***进行详细地说明。
基于如图1所示的通信***，本发明实施例提供一种数据传输方法。如图2所示，该数据传输方法可以包括下述的步骤201-步骤203。
步骤201、UE获取第一标识。
其中，上述第一标识可以用于指示逻辑信道或者调度第一传输信道，该第一标识所在的域包括N个比特位。若该第一标识用于指示逻辑信道，则N为大于6的整数；或者，若 该第一标识用于调度第一传输信道，则N为大于16的整数。
可选的，本发明实施例中，在第一标识用于指示逻辑信道的情况下，该第一标识可以为逻辑信道标识(logical channel identify，LCID)。在第一标识用于调度第一传输信道的情况下，该第一标识可以为小区无线网络临时标识(cell radio network temporary identity，C-RNTI)。
需要说明的是，在第一标识用于指示逻辑信道的情况下，与现有技术LCID所在的域包括6个比特位有所不同，本发明实施例提供的LCID(即第一标识)所在的域包括N个比特位(N为大于6的整数)。在第一标识用于调度第一传输信道的情况下，与现有技术C-RNTI所在的域包括16个比特位有所不同，本发明实施例提供的C-RNTI(即第一标识)所在的域包括N个比特位(N为大于16的整数)。
可选的，本发明实施例中，上述第一标识可以为通信协议中定义的，也可以为接入网设备为UE配置的。具体的，若第一标识为通信协议中定义的，则UE可以通过读取通信协议获取第一标识；若第一标识为接入网设备为UE配置的，则UE可以从接入网设备接收第一标识。具体可以根据实际使用需求确定，本发明实施例不做限定。
可以理解，当接入网设备为UE配置第一标识时，接入网设备可以从通信协议中读取第一标识，接入网设备也可以通过其他可能的方式获取第一标识。具体可以根据实际使用需求确定，本发明实施例不做限定。
可选的，本发明实施例中，在上述第一标识用于指示逻辑信道的情况下，上述N个比特位可以包括第一比特位，该第一比特位可以为MAC子头中的预留比特位或者扩展比特位。
需要说明的是，本发明实施例中，上述预留比特位或者扩展比特位可以为MAC子头中的空闲比特位，即尚未被占用的比特位。例如，预留比特位可以为MAC子头中原有的空闲比特位；扩展比特位可以为MAC子头中新增的空闲比特位。
可以理解，在第一标识用于指示逻辑信道的情况下，由于N个比特位中的第一比特位为MAC子头中的预留比特位或者扩展比特位，因此，本发明实施例扩展了LCID所在的域包含的比特位的数量，如此解决了现有技术LCID的数量可能无法满足传输的问题，从而可以支持UE与接入网设备之间建立更多的无线承载，进而可以满足日益增长的UE业务需求。
进一步的，本发明实施例中，在第一比特位为MAC子头中的预留比特位的情况下，N个比特位可以为6+M个比特位，且该第一比特位可以为该6+M个比特位中的M个比特位。其中，M为正整数。

示例性的，图3为本发明实施例提供的几种第一标识的示意图。在第一标识为LCID、且第一比特位为MAC子头中的预留比特位的情况下，假设M为1，那么第一标识所在的域可以包括7个比特位，且第一比特位可以为7个比特位中的1个预留比特位。具体的，如图3中的(a)或者如图3中的(b)所示，该1个预留比特位可以为LCID所在的域中与“F”域相邻的1个比特位(即如图3中的(a)或者如图3中的(b)所示的“1”对应的比特位)。如图3中的(c)所示，该1个预留比特位可以为LCID所在的域中与“R” 域相邻的1个比特位(即如图3中的(c)所示的“1”对应的比特位)。其中，“L”用于指示服务数据单元(service data unit，SDU)或者控制消息的长度；“R”为预留比特位；“F”用于指示SDU或者控制消息的长度是否大于128字节，具体的，若F＝1，则“F”用于指示SDU或者控制消息的长度大于128字节，若F＝0，则“F”用于指示SDU或者控制消息的长度小于或等于128字节。
可以理解，在第一标识用于指示逻辑信道的情况下，通过将MAC子头中的预留比特位设置为第一比特位，既可以保证MAC子头的正常使用，也可以扩展第一标识所在域的比特数。如此解决了现有技术LCID的数量可能无法满足传输的问题，从而可以支持UE与接入网设备之间建立更多的无线承载，进而可以满足日益增长的UE业务需求。
进一步的，本发明实施例中，在第一比特位为MAC子头中的扩展比特位的情况下，N个比特位为6+8*K个比特位，且该第一比特位为该6+8*K个比特位中的K个字节对应的比特位。其中，K为正整数。

可以理解，在第一标识用于指示逻辑信道的情况下，通过将MAC子头中的扩展比特位作为第一比特位，既可以保证MAC子头的正常使用，也可以扩展第一标识所在域的比特数。如此解决了现有技术LCID的数量可能无法满足传输的问题，从而可以支持UE与接入网设备之间建立更多的无线承载，进而可以满足日益增长的UE业务需求，并提供更好的服务质量。
