Description

传输数据的方法、终端设备和网络设备 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及传输数据的方法、终端设备和网络设备。
背景技术
车联网系统是基于长期演进车辆到车辆(Long Term Evaluation Vehicle to Vehicle，LTE V2V)的一种侧行链路(Sidelink，SL)传输技术，与传统的LTE系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，因此，具有更高的频谱效率以及更低的传输时延。
在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)Rel-14中对车联网技术车辆到其他设备(Vehicle to Everything，V2X)进行了标准化，定义了两种传输模式：模式3和模式4。具体而言，在模式3中，如图1所示，车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的，车载终端根据基站110分配的资源在侧行链路上进行数据的发送；基站110可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。在模式4中，如图2所示，车载终端(车载终端131和车载终端132)采用侦听(sensing)加预留(reservation)的传输方式，终端在侧行链路的资源上自主选取传输资源进行数据传输。
现有技术中，在模式4下，终端设备可以通过设置传输资源的选取范围，限定最大的传输时延。但是，在模式3下，终端设备的传输资源是由基站分配的，因此如何保证基站分配的传输资源满足终端设备的时延要求是本领域急需解决的问题。

具体实施方式
下面将结合附图，对本发明实施例中的技术方案进行描述。
本发明实施例可以适用于任何终端设备到终端设备的通信框架。例如，车辆到车辆(Vehicle to Vehicle，V2V)、车辆到其他设备(Vehicle to Everything，V2X)、终端到终端(Device to Device，D2D)等。也就是说，图1或图2所示的车载终端到车载终端的系统框架仅仅是本发明实施例的一个示例，本发明实施例不限于此。
其中，本发明实施例中的终端设备可以是任何配置有物理层和媒体接入控制层的设备或装置，终端设备也可称为接入终端。例如，用户设备(User  Equipment，UE)、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。接入终端可以是蜂窝电话、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、个人数字线性处理(Personal Digital Assistant，PDA)、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线性处理设备、车载设备、可穿戴设备等等。本发明实施例以车载终端为例进行说明，但并不限于此。
图3是本发明实施例的终端设备侦听资源池的方法的示意性流程图。
如图3所示，假设每个载波对应至少一个侧行链路进程(sidelink process)。例如，3GPP rel-14中是一个载波对应两个侧行链路进程。当在时刻n有新的数据包到达，终端设备需要进行资源选取，终端会根据过去一段时间(例如，1s)中的侦听结果，在[n+T1，n+T2]区间内进行资源选取。具体地，终端设备可以通过侦听窗内检测到资源对应的信道质量的信息在选择窗中选取资源。
其中，T1≤4ms；20ms≤T2≤100ms。
此外，资源对应的信道质量信息可以是物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)对应的物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)的信道质量(例如，接收功率或者接收质量)。终端设备还可以通过对该传输资源集合中的资源进行接收信号强度指示(Receive Signal Strength Indicator，RSSI)检测，获取该传输资源集合中每个资源对应的信道质量的信息。
应注意，该T1和T2的取值范围仅作为一个示例，不应限定本实施例。
由于车联网系统中的业务具有周期性特征。因此，本发明实施例中，终端设备可以采用半静态传输的方式。
具体而言，当终端设备选取了一个资源进行传输，则该终端设备会持续使用预留这个资源Cresel次，每传输一次数据，Cresel减1，当Cresel减到0时，终端会随机生成一个[0，1]之间的随机数，并且与参数(probResourceKeep)比较，如果大于该参数，终端进行资源重选，如果小于该参数，终端继续使用该资源，并且重新设置Cresel。
即，本发明实施例的终端设备会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端设备可以通过检测该终端设备的控制信 息判断这块资源是否被该终端设备预留和使用，达到降低资源冲突的目的。换句话说，本发明实施例的终端设备在选取一个传输资源后，可以通过在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。
可以发现，在终端设备通过侦听资源池获取传输资源时，终端设备可以通过设置传输资源的选取范围，限定最大的传输时延。但是，终端设备的传输资源是由网络设备分配时，如何保证网络设备分配的传输资源满足终端设备的时延要求是本领域急需解决的问题。
本发明实施例中，提供了一种传输数据的方法，通过向网络设备指示终端设备的时延要求，使得网络能够根据终端指示的时延要求，为终端分配满足该时延要求的传输资源，进而达到减小传输时延、提升用户体验的目的。
图4是本发明实施例的传输数据的方法的示意性流程图。
如图4所示，该方法包括：
210，终端设备生成指示信息，该指示信息用于指示该终端设备的时延要求；
220，该终端设备向网络设备发送该指示信息。
230，根据该指示信息，为该终端设备分配传输资源
简而言之，终端设备向网络上报传输时延需求。使得网络设备能够根据终端设备上报的传输时延，为终端设备分配满足该时延要求的传输资源。进而减小传输时延，提升用户体验。
本发明的指示信息的作用是：用于指示终端设备的时延要求。但是，需要注意的是，本发明对具体地指示模式不做限定。例如，可以指示终端设备在一段时间内的时延要求(即，半静态指示)，也可以指示终端设备固定的时延要求(即，静态指示)，还可以指示终端设备的业务的时延要求(即，动态指示)。
应理解，本发明实施例中提及的网络设备指可用于与终端设备进行通信的任何设备。例如，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者该网络设备可以为中继站、 接入点、车载设备、可穿戴设备以及5G网络中的网络设备等。
下面介绍本发明实施例的终端设备向网络设备发送指示信息的实现方式。
作为一个实施例，该终端设备可以向该网络设备发送辅助信息，该辅助信息用于该网络设备为该终端设备分配传输资源，该辅助信息包括该终端设备的业务周期和该指示信息。换句话说，网络设备接收终端设备发送的指示信息，该指示信息用于指示终端设备的时延要求；该网络设备根据该指示信息，为该终端设备分配传输资源。
例如，该辅助信息可以是半静态调度(Semi-Persistent Scheduling，SPS)辅助信息(Assistance Information)。
更具体地，终端设备可以将指示信息携带在SPS Assistance Information中，发给网络设备。网络设备在接收到该SPS Assistance Information中的指示信息后，为终端设备配置半静态资源。终端设备在网络设备分配的半静态资源上传输数据。
本发明实施例中，终端设备不仅能够获取满足时延要求的传输资源，而且能够在获取传输资源后，通过在多个传输周期中持续的使用该资源，进而降低资源重选以及资源冲突的概率。
又例如，该辅助信息还可以包括某个业务的大小信息。使得网络设备在接收到该辅助信息后，能够为这个业务专门分配能够满足时延要求的传输资源。
作为另一个实施例，该终端设备可以向该网络设备发送侧行链路信息(Sidelink UE Information)，该侧行链路信息用于指示该终端设备的侧行链路的信息，该侧行链路信息包括该指示信息。
具体地，现有技术中，如果终端设备支持侧行链路(sidelink，SL)能力且终端需要进行sidelink传输时，终端设备需要通过Sidelink UE Information消息上报终端的SL能力。
本发明实施例中，终端设备向网络设备上报该侧行链路信息，并将指示终端设备时延要求的指示信息携带在该侧行链路信息中，从而辅助网络设备进行资源调度。
作为另一个实施例，该终端设备可以向该网络设备发送该终端设备的业务的优先级信息，该优先级信息用于指示该终端设备的时延要求。即，该网 络设备根据该优先级信息指示的该终端设备的时延要求，为该终端设备分配该传输资源。
例如，该优先级信息包括邻近业务每个业务包优先级(Prose Per-Packet Priority，PPPP)。
具体而言，不同的PPPP等级对应不同的传输时延需求，PPPP与传输时延之间的对应关系可以是预配置，或者是网络设备配置的；网络设备根据终端上报的业务优先级，确定相应的传输时延，并且为该用户分配满足该传输时延的传输资源。
作为另一个实施例，该终端设备可以向该网络设备发送服务质量QoS等级，该QoS等级用于指示该终端设备的时延要求。换句话说，该网络设备可以根据该QoS等级指示的该终端设备的时延要求，为该终端设备分配该传输资源。
具体地，终端设备可以通过预配置或者网络设备配置的方式，定义多个QoS等级与多个时延要求之间有对应关系。由此，网络设备可以根据该QoS等级指示的该终端设备的时延要求，为该终端设备分配该传输资源。
作为另一个实施例，该终端设备可以向该网络设备发送缓冲状态报告(Buffer Status Report，BSR)，该BSR包括目的标识和逻辑信道组标识，上述目的标识和/或逻辑信道组标识用于指示该终端设备的时延要求。换句话说，该网络设备根据上述目的标识和/或逻辑信道组标识指示的该终端设备的时延要求，为该终端设备分配该传输资源。
具体地，终端设备可以通过预配置或者网络设备配置的方式，定义一个目的标识(Destination Index)或者逻辑信道组标识(Logical Channel Group Identification ID，LCG ID)和时延要求之间的对应关系，从而辅助该网络设备进行调度。
其中，Destination Index可以指示邻近服务(Proximity-based Services)通信的通信目标。例如，车联网通信的通信目标，LCG ID表示逻辑信道组的ID。
应理解，在本发明实施例中，该终端设备向网络设备发送该指示信息后，还可以接收该网络设备发送的调度信息，该调度信息包括该网络设备为该终端设备分配的传输资源；该终端设备在该传输资源上传输数据。即，该网络设备向该终端设备发送调度信息，该调度信息包括该网络设备为该终端设备 分配的传输资源。
还应理解，上述实施例仅是本发明实施例的示例性说明，不应限定本发明实施例。
例如，终端设备还可以直接给网络设备发送该指示信息。
还需要注意的是，本发明实施例中，终端设备可以显示地指示网络设备该终端设备的时延要求，终端设备也可以隐式地指示网络设备该终端设备的时延要求。本发明实施例不做具体限定。
例如，终端设备显示地指示网络设备该终端设备的时延要求时，可以直接向网络设备发送用于指示终端设备的时延要求的指示信息，也可以向网络设备发送辅助信息或者侧行链路信息，该辅助信息或者侧行链路信息包括该指示信息。
又例如，终端设备隐式地指示网络设备该终端设备的时延要求时，可以通过优先级信息、QoS等级、BSR包括目的标识和逻辑信道组标识隐式地指示网络设备该终端设备的时延要求。
举例来说，假设终端设备通过QoS等级隐式地指示网络设备该终端设备的时延要求。针对终端设备来说，终端设备只需要向网络设备发送该终端设备的QoS等级。针对网络设备来说，网络设备在接收到该终端设备的QoS等级，可以通过该终端设备的QoS等级确定出该终端设备的时延要求
具体地，网络设备可以通过多个QoS等级与多个时延要求之间的对应关系，确定该终端设备的QoS等级对应的时延要求，其中，该终端设备的QoS等级属于该多个QoS等级。
更进一步地，网络设备可以预配置给终端设备该对应关系，或者网络设备与终端设备协商确定该对应关系。

生成单元310，用于生成指示信息，该指示信息用于指示该终端设备的时延要求；收发单元320，用于向网络设备发送该指示信息。

又例如，取决于语境，如在此所使用的词语“在......时”可以被解释成为“如果”或“若”或“当......时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
本领域普通技术人员可以意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以电子硬件、或者计算机软件和电子硬件的结合来实现。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明实施例的范围。
所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如，多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本发明实施例的目的。
另外，在本发明实施例中的各功能单元可以集成在一个处理单元中，也 可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本发明实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器、随机存取存储器、磁碟或者光盘等各种可以存储程序代码的介质。
以上内容，仅为本发明实施例的具体实施方式，但本发明实施例的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明实施例揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明实施例的保护范围之内。因此，本发明实施例的保护范围应以权利要求的保护范围为准。
