Description

一种通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术

XR数据的一个特性是数据之间存在一定的依赖关系。例如对于XR数据中的视频画面帧，一般可以被分为多个数据包，而这多个数据包中某个数据包传输出现失败，就有可能导致整个视频画面帧无法被正确接收。又例如在触觉互联网中，视频信息、触觉信息和控制信息等信息是具有内在关联关系的数据，当其中某类信息的传输出现丢失时或者延迟时，会影响整体业务的效果和用户体验。
随着XR技术的发展，XR业务对上行传输的速率需求也越来越高。例如，AR上行需要传输数据。以上行传输视频为例，根据业界的评估，满足AR初级体验所需的上行传输速率约2Mbps，满足进阶体验需要高达10Mbps。此外，在视频业务的上行传输中，对于每一个视频帧的传输，目前使用较多的是将视频帧在网络传输层分成几十个的数据包，在网络传输过程中，如果其中一个数据包传输出错，则会导致整个视频帧无法恢复。因此，如何能够保证上行数据能够正确传输，从而提升上行XR业务的传输效率，成为亟需解决的问题。

在无线通信网络中，XR技术具有多视角、交互性强等优点，能够为用户提供了一种全新的体验，具有极大的应用价值和商业潜力。XR包含VR、AR和MR等技术，能够广泛应用于娱乐、游戏、医疗、广告、工业、在线教育、以及工程等诸多领域。VR技术主要是指对视觉和音频场景的渲染以尽可能地模拟现实世界中的视觉和音频对用户的感官刺激，VR技术通常要求用户佩戴XR终端(例如头戴式设备)进而向用户模拟视觉和/或听觉。VR技术还可以对用户进行动作跟踪，从而及时更新模拟的视觉和/或听觉内容。AR技术主要是指在用户感知的现实环境中提供视觉和/或听觉的附加信息或人工生成内容，其中，用户对现实环境的获取可以是直接的(例如不进行感测、处理和渲染)，也可以是间接的(例如通过传感器等方式进行传递)，并进行进一步的增强处理。MR技术是将一些虚拟元素插入到物理场景中，目的是为用户提供一种这些元素是真实场景一部分的沉浸体验。网络设备可以对XR业务产生的数据(可称为XR数据)进行处理和传输，例如云端的网络设备可以对XR的源数据进行渲染和编码(比如信源编码)，借助核心网和/或接入网的网络设备将XR数据传输到XR终端。XR终端通过对XR数据的处理为用户提供多样化的XR体验(例如沉浸体验、视觉体验、交互体验或设备体验等)。XR体验有多种不同的评价维度，例如包括以下评价维度中的一种或多种：画面清晰度、画面流畅度、画面畸变、画面立体感、画面黑边、画面拖影、音质、音效、视场角、卡顿感、花屏感、眩晕感、音视频同步、交互自由度、交互操作响应速度、交互操作精准度、交互内容加载速度、终端佩戴舒适度、终端佩戴疲劳感、终端续航能力、终端便携度、或终端视力障碍友好度等。
本申请中的实施例为XR数据的上行传输提供了一种通信方法，在该方法中对具有同步要求或内在关联依赖关系的数据进行完整性传输，满足数据间的同步需求，从而提升XR业务的传输效率。
本申请中对数据的完整性传输可以理解为将两个或两个以上的数据视为一个整体进行传输。其中，完整性针对的对象可以有多种不同的理解。
例如，完整性的对象可以是内容(content)，即内容完整性。多个不同维度(比如XR业务中的音频和视频)的内容具有关联关系，因此对该多个维度的内容对应的多个数据进行完整性传输。比如一幅画面帧内容对应的多个数据之间具有关联关系，一幅画面帧内容对应的基本层数据或增强层数据之间具有关联关系，画面帧数据与音频数据之间具有关联关系等。
又例如，完整性的对象也可以是任务、事件、对象或类，即任务完整性、事件完整性、对象完整性或类完整性。同一任务、同一事件、同一对象或同一类中的多个数据具有关联关系，例如，对于触觉互联网，可将动作信息、触觉信息、画面帧、或音频信息等信息中的一项或多项作为同一任务、同一事件、同一对象或同一类的数据，该同一任务，同一时间，同一对象或同一类的数据可以属于同一数据单元，进而对同一任务、同 一事件、同一对象或同一类中的多个数据进行完整性传输。
可以理解，本申请中的完整性传输以及完整性对象也可以有其它描述。例如，上述完整性传输也可以描述为基于任务驱动的传输、或者基于事件的传输、或者面向对象的传输等，均在本申请范围内。
在本申请中，为了表述统一，对上述所描述的完整性的对象表述为一个数据单元，该数据单元中待传输的任意一个数据包，或者关联其他维度的数据单元中的任意一个数据包表述为第一信息，可以理解，一个数据单元中可以包含一个或多个第一信息。

在一种可能的实施例中，如果本申请中的第一信息只有一个时，上述610至620的过程对终端设备仍适用，上述过程中核心网设备为终端设备待发送的第一信息配置满足传输需求的服务质量流，以提升终端设备的第一信息的传输效率。
630：终端设备基于服务质量流向接入网设备发送第一信息。相应的，接入网设备接收来自终端设备的第一信息。上述第一信息包含第二标识。
在本申请中，对数据单元和第一信息的定义，在前文中已经有具体描述。可以理解，被视为一个整体进行传输的数据为一个数据单元，该数据单元中的数据可以分割成一个或多个数据包。其中待传输的任意一个数据包，或者关联其他维度的任意一个数据包可理解为第一信息。例如，一个数据单元中包含一个或多个第一信息。当数据单元中包含一个或多个第一信息时，该等第一信息均包含第二标识。
在本实施例中，当有完整性传输需求的数据单元有两个或两个以上的第一信息时，第二标识在该两个或两个以上的第一信息中是相同的。可以理解，相同的第二标识可以由多种实现方式。例如，第二标识的呈现方式可以相同，如都为相同的比特位、索引号、或比特地图；指代内容可以相同或关联，如都指示相同或关联的信息等。本文并没有限定第二标识本身是否必须相同，例如不同的第二标识分别为比特位或索引号，但只要其指代的内容为关联信息如一个或相同的数据单元，或一个数据单元中的多个第一信息，也可以认为该第二标识是相同的。
在一种可能的实施方式中，具有相同第二标识的两个或两个以上的第一信息可以对应于同一幅画面帧的数据，同一幅画面帧的数据可以属于同一数据单元，这样可以使得对应于同一幅画面帧的多个第一信息所包含的数据后续可以被终端设备作为一个整体进行传输，避免终端设备因为接入网丢包而重传，从而提升终端设备的传输效率。
在另一种可能的实施方式中，具有相同第二标识的两个或两个以上的第一信息可以对应于同一数据包组的数据，同一数据包组的数据属于同一数据单元，可以使得对应于同一数据包组的多个第一信息所包含的数据后续可以在终端设备被视为一个整体进行传输，避免终端设备因为接入网丢包而重传，从而提升终端设备的传输效率。

在另一种可能的实施方式中，具有相同第二标识的两个或两个以上的第一信息可以对应于同一任务、同一事件、同一对象或同一类的数据。例如，对于触觉互联网，可将 动作信息、触觉信息、画面帧、或音频信息等信息中的一项或多项作为同一任务、同一事件、同一对象或同一类的数据，该同一任务，同一时间，同一对象或同一类的数据可以属于同一数据单元，这样可以使得对应于同一任务、同一事件、同一对象或同一类的数据的多个第一信息所包含的数据后续可以在终端设备被视为一个整体进行传输，避免终端设备因为接入网丢包而重传，从而提升终端设备的传输效率。
当有完整性传输需求的数据单元只有一个第一信息时，第一信息就是一个整体进行传输，第二标识仍然可以携带于该第一信息中。
第二标识用于标识上述多个第一信息属于同一个数据单元，后续可以在终端设备被视为一个整体进行传输，第二标识可以是完整性标记信息。可以理解，本申请实施例并不限定完整性标记信息的具体名称，完整性标记信息仅仅是一种可能名称，其他任何能够实现上述功能的信息都应被理解为本申请方案中的完整性标记信息。

可选的，该数据单元的生成时间信息可以是对被视为一个整体进行传输的数据单元的生成时间进行标识。接入网设备获知数据单元的生成时间信息，有利于及时获得终端设备发送第一信息的时间，进而可以协助接入网设备调整为终端设备调度的上行资源。
在一种可能的实施例中，数据单元的标记信息可以是上述几种形式中的一种，例如 数据单元的标记信息是该数据单元中第一信息的数量，或者数据单元的标记信息是该数据单元的标识，或者数据单元的标记信息是该数据单元的生成时间信息，或者数据单元的标记信息是该数据单元的数据量。
在另一种可能的实施例中，数据单元的标记信息可以是上述几种形式中的组合：
例如，数据单元的标记信息是该数据单元的标识和该数据单元中第一信息的数量，该数据单元的标记信息能够让接入网设备识别出一个数据单元包含多少第一信息，以及哪些第一信息属于该数据单元。例如，一个画面帧的数据是一个数据单元，而该画面帧的数据被分为一个或多个数据包，每个数据包就是一个第一信息，终端设备发送数据包时，每个数据包中的第二标识包含该画面帧的帧标识和数据包数量，接入网设备接收数据包时，检测到第二标识，可以获知该画面帧的帧标识和数据包数量，进而获知作为一个整体进行传输的数据包数据量。
例如，数据单元的标记信息是该数据单元的标识和该数据单元的数据量，该数据单元的标记信息能够让接入网设备识别出属于该数据单元的第一信息和数据单元总的数据量，接入网设备统计接收的包含第二标识的第一信息的数据量之和，进而获知作为一个整体进行传输的第一信息的数量。
可以理解，本申请实施例中数据单元的标记信息并不局限于上述所举示例，其他可能的形式都应被理解为本申请方案中数据单元的标记信息。
在另一种可能的实施方式中，第二标识可以携带于第一信息的包头中，或者携带于第一信息的负载中。示例性地，如图7所示，第二标识携带于第一信息的包头中。例如，可以在实时传输协议(Real-time Transport Protocol,RTP)与用户数据报协议(User Datagram Protocol，UDP)之间新增一个字段，该字段用于存储第二标识。可以理解，第二标识在第一信息包头中的位置不限于所举示例。
在另一种可能的实施方式中，同一数据单元的一个或多个第一信息中携带第二标识时，终端设备还可以对同一数据单元的一个或多个第一信息中增加第三标识，该第三标识用于标识同一数据单元的任意一个第一信息。例如，终端设备发送N个第一消息，每个第一消息中均包含第三标识，即第三标识数量也有N个。
第三标识的标记信息可以有多种形式，例如，
第一信息在所属的数据单元中的索引信息；
第一信息的标识；
第一信息的数据量。
第一信息中携带的第三标识可以是上述几种形式中的其中一种，或者是其中几种的组合。例如，第三标识是第一信息的标识和第一信息的数据量，或者第三标识是第一信息在所属的数据单元中的索引信息和第一信息的数据量。可以理解，本申请实施例中第三标识并不局限于上述所举示例，其他可能的形式都应被理解为本申请方案中第三标识的内容。在一种可能的实施方式中，第三标识可以携带于第一信息的包头中，或者携带于第一信息的负载中。可以理解，在本申请实施例中，第三标识在第一信息中的位置不做限制。在另一种可能的实施方式中，一个数据单元只有一个第一信息时，上述步骤仍适用。其中第三标识的标记信息与第二标识的标记信息可能相同，可能不同，当第三标识与第二标识相同时，例如，第一信息的数据量与数据单元的数据量相同，或者第一信息的标识 与数据单元的标识相同。此时，第一信息只需要携带第二标识或者第三标识中的其中一个。当第三标识与第二标识不同时，例如，第二标识是数据单元的生成时间信息，或者服务质量流的标识，第三标识是第一信息的标识或者第一信息的数据量，此时，第一信息可以携带第二标识和第三标识。
在本申请中，终端设备是基于网络设备配置的服务质量流发送第一信息。相应的，接入网设备基于上述服务质量流接收该第一信息。可选的，接入网设备会将接收到的第一信息再发送给用户面网元。
可选地，接入网和/或用户面网元对接收到的第一信息检测，从而获得第二标识，根据第二标识，将接收到的具有相同第二标识的两个或两个以上的第一信息视为一个整体。
在一种可能的实施方式中，接入网设备和/或UPF对接收到的第一信息检测，获得第二标识中携带的第一信息的数量，如果接入网设备和/或用户面网元接收到的第一信息的数量与第二标识中携带的第一信息的数量不同时，接入网设备和/或用户面网元会主动丢弃接收到的第一信息。
在一种可能的实施方式中，接入网设备和/或用户面网元对接收到的第一信息检测，获得第二标识中携带的数据单元的标识，接入网设备和/或用户面网元根据数据单元的标识确定终端需要优先传输的数据，可以为终端设备分配上行的传输资源，以保证属于同一数据单元的数据尽快传输，保障端到端的数据传输时延满足要求。
在另一种可能的实施方式中，接入网设备和/或用户面网元对接收到的第一信息检测，获得第二标识中携带的数据单元的数据量，接入网设备和/或用户面网元根据数据单元的数据量，确定需要优先传输的数据，可以为终端设备分配上行的传输资源，以保证属于同一数据单元的数据尽快传输，保障端到端的数据传输时延满足要求。
在本申请实施例中，基于前述步骤的描述，接入网设备获得第二标识后，可以获知第一信息的传输情况，进而确定是否需要为待传的第一信息调整上行资源，以提升作为整体传输的数据单元的传输效率。为了进一步满足作为整体传输的数据单元的传输需求，终端设备可以提前向接入网设备发送第一信息所属的数据单元的标记信息，这样接入网设备提前获知作为一个整体进行传输的数据单元的标记信息，接入网设备就可以提前为终端设备待传输的第一信息调度合适的上行资源，以保证上行传输效率。
因此，可选的，在本申请实施例中，在终端设备发送多个第一信息前，向接入网设备发送该多个第一信息所属的数据单元的标记信息。如果作为整体传输的第一信息只有一个时，终端设备在该第一信息发送前，也可以向接入网设备发送该第一信息所属的数据单元的标记信息。为了与第一信息中的第二标识区别，终端设备提前发送上述标记信息，我们称之为第四标识信息。
具体的步骤描述见图6中的640。
640：终端设备发送第四标识，相应的，接入网设备接收该第四标识。
第四标识是终端设备在发送一个或多个第一信息之前，向接入网设备发送第四标识。
终端设备向接入网设备发送第四标识，是向接入网设备上报终端设备待发送的一个或多个第一信息中携带的第二标识，因此，可以理解，第四标识中包含第二标识的全部内容或者第二标识的部分内容。根据上文中对第二标识所包含内容的解释，可以理解， 第四标识可以包含待发送的一个或多个第一信息在传输时的服务质量流标识，和/或待发送的一个或多个第一信息所属的数据单元的标记信息中的一种或多种信息。
具体地，第四标识可以包含终端设备待发送的一个或多个第一信息所属的数据单元的标记信息，数据单元的标记信息可以有多种形式，包含下述信息中的一种或多种：
该数据单元中第一信息的数量，
该数据单元的标识，
该数据单元的生成时间信息，
该数据单元的数据量。
对上述信息的具体描述可以参考前述方法实施例中620部分中对数据单元的标记信息的描述，这里不再赘述。
相应的，接入网设备收到第四标识后，可以获知终端设备待传输的一个或多个第一信息被视为同一整体进行传输，接入网设备可以根据第四标识对终端设备要发送的视为同一整体的一个或多个第一信息调度上行传输资源，以保证终端设备可以尽快完成上行传输，达到完整性传输的目的，保障端到端的传输时间满足时延要求。

910：终端设备向接入网设备发送第四标识，相应的，接入网设备接收第四标识。
在本申请实施例中，终端设备将属于同一数据单元的多个第一信息视为一个整体进行传输，即终端设备待传输的数据单元具有完整性传输需求。当有完整性传输需求的数据单元有两个或两个以上的第一信息时，终端设备在每个第一信息中增加第二标识，该第二标识在该两个或两个以上的第一信息中是相同的，用于标记每个第一信息是属于同一数据单元的。具有相同第二标识的两个或两个以上第一信息在终端设备被视为一个整体进行传输，可以避免终端设备因为接入网丢包而重传，从而提升终端设备的传输效率。
当有完整性传输需求的数据单元只有一个第一信息时，第一信息就是一个整体进行传输，第二标识仍然可以携带于该第一信息中。
对于第二标识的表述、第二标识的形式和第二标识在第一信息中的位置，可以参考前述方法实施例中630部分的对应描述，此处不再赘述。
在发送多个第一信息之前，终端设备向接入网设备发送第一信息所属的数据单元的标记信息，这样接入网设备提前获知作为一个整体进行传输的数据单元的标记信息，接入网设备就可以提前为终端设备待传输的第一信息调度合适的上行资源，以保证上行传输效率。为了与第一信息中的第二标识区别，终端设备提前发送上述标记信息，我们称之为第四标识。
如果作为整体传输的第一信息只有一个时，终端设备在该第一信息发送前，也可以向接入网设备发送该第一信息所属的数据单元的标记信息。
为了与第一信息中的第二标识区别，终端设备提前发送上述标记信息，我们称之为第四标识。
因此，终端设备向接入网设备发送第四标识，是向接入网设备上报终端设备待发送的一个或多个第一信息中携带的第二标识，可以理解，第四标识中包含第二标识的全部内容或者第二标识的部分内容。根据上文中对第二标识所包含内容的解释，可以理解，第四标识可以包含待发送的一个或多个第一信息在传输时的服务质量流标识，和/或待发送的一个或多个第一信息所属的数据单元的标记信息中的一种或多种信息。
具体地，第四标识可以包含终端设备待发送的一个或多个第一信息所属的数据单元的标记信息，该标记信息可以有多种形式，包含下述信息中的一种或多种：
该数据单元中第一信息的数量，
该数据单元的标识，
该数据单元的生成时间信息，
该数据单元的数据量。
对上述信息的具体描述可以参考前述方法实施例中630部分中对数据单元的标记信息的描述，这里不再赘述。
相应的，接入网设备收到第四标识后，可以获知终端设备待传输的一个或多个第一信息被视为同一整体进行传输，接入网设备可以根据第四标识对终端设备待发送的视为同一整体的一个或多个第一信息调度上行传输资源，以保证终端设备可以尽快完成上行传输，达到完整性传输的目的，保障端到端的传输时间满足时延要求。
第四标识还可以包含上述一个或多个第一信息映射到的服务质量流的标识，接入网设备接收第四标识后，可获知该服务质量流标识所指示的服务质量流的配置信息。
可选地，第四标识还可以包含上述一个或多个第一信息所属的数据单元的的图像组Group of Picture，GoP)信息，GoP信息表示了该数据单元的重要程度，接入网设备根据该GoP信息，可以为该数据单元的传输调度更多个上行资源，以保证终端设备的上行传输效率和可靠性。
可选地，第四标识还可以包含所述一个或多个第一信息中首个第一信息到达接入网设备的时间信息，即首个第一信息的到达时间信息，而首个第一信息的到达时间信息也可以是首个第一信息被接入网设备接收的等待时长信息。接入网设备接收第四标识后，根据该 到达时间信息指示的时刻接收一个或多个第一信息，提升接入网设备接收数据的效率。
可选的，接入网设备收到第四标标识后，接入网设备会将接收到的第四标识发送给用户面网元，用户面网元获知终端设备待发送的一个或多个第一信息是被视为同一整体进行传输。
在本申请实施例中，第四标识的传输方式不做限制，可以有多种方式，例如：
在一种可能的实施方式中，终端设备的无线资源控制(radio resource control,RRC)层发送第四标识，相应的，接入网的无线资源控制层接收该第四标识。
终端设备的RRC层将第四标识以一种RRC信令的形式发送，第四标识可以是单独的一种RRC信令，或者第四标识可以是现有的RRC信令中的一部分，由此可以理解，第四标识在RRC层的传输形式在本申请实施例中不做限制。例如，在UE辅助信息消息(UEAssistanceInformation message)中携带第四标识。
在另一种可能的实施方式中，终端设备的多媒体接入控制(medium access control，MAC)层发送第四标识，相应的，接入网设备的多媒体接入控制层接收该第四标识。
终端设备的MAC层将第四标识以一种控制单元(control element)信令的形式发送，示例性地，第四标识的可以是一个完整性传输MAC CE,如图8a所示，该MAC CE是完整性传输MAC CE中的一种可能的形式，如图8b所示，该MAC CE是完整性传输MAC CE中的另一种可能的形式。可以理解，图8a和图8b所表述的完整性传输MAC CE的形式并未覆盖第四标识传输的可能形式，图8a和图8b中所表述的MAC CE中各个字段长度并不限制对应字段在MAC CE中的实际字段长度，仅作为示意解释。由此可以理解，第四标识在MAC层的传输格式和大小在本申请实施例中不做限制。
在另一种可能的实施方式中，终端设备的物理层发送第四标识，相应的，接入网设备的物理层接收该第四标识。

进一步地，在另一种可能的实施方式中，同一数据单元的一个或多个第一信息中携带第二标识时，终端设备可以在同一数据单元中一个或多个第一信息中增加第三标识，该第三标识用于标记同一数据单元中任意一个第一信息。例如，终端设备发送N个第一消息，每个第一消息中均包含第三标识，即第三标识数量也有N个。
对于第三标识的表述、第三标识的形式和第三标识在第一信息中的位置，可以参考前述方法实施例中630部分的对应描述，此处不再赘述。
在本申请中，终端设备是基于网络设备配置的服务质量流发送第一信息，相应的， 接入网设备基于上述服务质量流接收该第一信息。可选的，接入网设备会将接收到的第一信息再发送给用户面网元。
在一种可能的实施方式中，接入网设备和/或用户面网元对接收到的第一信息检测，获得第二标识中携带的第一信息的数量，如果接入网设备和/或用户面网元接收到的第一信息的数量与第二标识中携带的第一信息的数量不同时，接入网设备和/或用户面网元会主动丢弃接收到的第一信息。
在一种可能的实施方式中，接入网设备和/或用户面网元对接收到的第一信息检测，获得第二标识中携带的数据单元的标识，接入网设备和/或用户面网元根据数据单元的标识确定终端需要优先传输的数据，结合接收到的第四标识，可以确认为终端设备分配上行的传输资源是否需要调整，以保证属于同一数据单元的数据尽快传输，保障端到端的数据传输时延满足要求。
