Description

无线通信方法及设备 技术领域
本申请实施例涉及通信技术领域，并且更具体地，涉及一种无线通信方法及设备。
背景技术
在增强现实(Augmented Reality，AR)、虚拟现实(Virtual Reality，VR)或云游戏(Cloud gaming)等视频传输场景中涉及视频编码技术，视频编码技术通常包括：基于帧内预测和帧间预测的编码技术。基于此，目前存在帧内编码帧(I帧)，前向预测编码帧(P帧)和双向预测内插编码帧(B帧)。由此可知，视频帧之间具有一定的依赖关系，例如：某一P帧的参考帧是它的前一个I帧或者P帧。
目前接入网设备在获取到当前视频帧之后，并不能获知当前视频帧的参考帧的传输情况，而是直接将当前视频帧传输给终端设备，终端设备在接收到当前视频帧之后，判断当前视频帧的参考帧是否传输成功或解码成功，如果该参考帧传输失败或解码失败，终端设备将会丢弃当前视频帧，这将导致对空口资源的浪费。此外，在网络拥塞情况下，往往存在多个待传输视频帧，那么如何合理地调度空口资源是本申请亟待解决的技术问题。

通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
图1示例性地示出了一种本申请应用的通信系统100的示意图。如图1所示，该通信系统100主要包括终端设备(User Equipment，UE)101、接入网(Access Network，AN)设备102、接入与移动性管理功能(Access and Mobility Management Function，AMF)实体103、会话管理功能(Session Management Function，SMF)实体104、用户面功能(User Plane Function，UPF)实体105、策略控 制功能(Policy Control function，PCF)实体106、统一数据管理(Unified Data Management，UDM)实体107、数据网络(Data Network，DN)108、应用功能(Application Function，AF)实体109、鉴权服务器功能(Authentication Server Function，AUSF)实体110、网络切片选择功能(Network Slice Selection Function，NSSF)实体111。
具体地，在通信系统100中，UE 101通过Uu接口与AN设备102进行接入层连接，以交互接入层消息及无线数据传输，UE 101通过N1接口与AMF实体103进行非接入层(Non-Access Stratum，NAS)连接，以交互NAS消息；AN设备102通过N2接口与AMF实体103连接，以及AN设备102通过N3接口与UPF实体105连接；多个UPF实体105之间通过N9接口连接，UPF实体105通过N6接口与DN 108连接，同时，UPF实体105通过N4接口与SMF实体104连接；SMF实体104通过N7接口与PCF实体106连接，SMF实体104通过N10接口与UDM实体107连接，SMF实体104通过N4接口控制UPF实体105，同时，SMF实体104通过N11接口与AMF实体103连接；多个AMF实体103之间通过N14接口连接，AMF实体103通过N8接口与UDM实体107连接，AMF实体103通过N12接口与AUSF实体110连接，AMF实体103通过N22接口与NSSF实体111连接，同时，AMF实体103通过N15接口与PCF实体106连接；PCF实体106通过N5接口与AF实体109连接；AUSF实体110通过N13接口与UDM实体107连接。
在通信系统100中，UDM实体107是核心网中的签约数据库，存储用户在5G网络中的签约数据。AMF实体103是核心网中的移动性管理功能，SMF实体104是核心网中的会话管理功能，AMF实体103在对UE 101进行移动性管理之外，还负责将从会话管理相关消息在UE 101和SMF实体104之间的转发。PCF实体106是核心网中的策略管理功能，负责制定对UE 101的移动性管理、会话管理、计费等相关的策略。UPF实体105是核心网中的用户面功能，通过N6接口与外部数据网络进行数据传输，通过N3接口与AN设备102进行数据传输。UE 101通过Uu口接入5G网络后，在SMF实体104的控制下建立UE 101到UPF实体105的协议数据单元(Protocol Data Unit，PDU)会话数据连接，从而进行数据传输。AMF实体103和SMF实体104分别通过N8和N10接口从UDM实体107获取用户签约数据，通过N15和N7接口从PCF实体106获取策略数据。
另外，通信系统100中还存在网络开放功能(Network Exposure Function，NEF)实体，用于与第三方应用服务器接口，在核心网节点与第三方应用之间进行信息传递。
需要说明的是，上述通信系统100是以第五代(5rd Generation，5G)通信系统为例进行说明，当然，本申请也可以适用于其他第三代移动通信标准化组织(3rd Generation Partnership Project，3GPP)通信系统，例如第四代(4rd Generation，4G)通信系统，或者未来的3GPP通信系统，本申请对此并不限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例结合终端设备、接入网设备和核心网设备描述了各个实施例，其中：终端设备也可以称为用户设备、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等。终端设备可以是WLAN中的站点(STAION，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，NR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。
上述接入网设备可以是用于与移动设备通信的设备，接入网设备可以是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NR网络中的基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，接入网设备可以为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与接入网设备进行通信，该小区可以是接入网设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图2为5G网络的服务质量(Quality of Service，QoS)模型的示意图，如图2所示，在5G网络中QoS控制基于QoS流粒度进行控制，UE通过Uu口接入5G网络后，在SMF的控制下建立QoS流进行数据传输，SMF向基站提供每个QoS流的QoS流配置信息，具体包括5G QoS标识(5G QoS Identifier，5QI)，地址解析协议(Address Resolution Protocol，ARP)，还可以包括码率要求等信息，其中5QI是一个可以对应到例如时延、误码率要求等QoS特征的索引值，ARP为基站为QoS流分配或者保持资源的优先级。对于每个QoS流，基站根据从SMF收到的QoS流配置信息调度无线资源对QoS流的QoS要求进行保证。
图3示例性地示出了一种用户面协议栈的示意图，如图3所示，UPF最多可以解析到数据包的PDU层，例如UPF可以解析数据包的网络协议(Internet Protocol，IP)层，但是无法解析到应用层。另外，接入网设备也最多解析到GTP用户面部分(User Plane Part of GTP，GTP-U)层，也无法解析到应用层。通常数据包的应用层包头信息可以携带有与该数据包具有依赖关系的数据集合的信息，例如：一个当前视频帧可以包括至少一个数据包，这些数据包的应用层包头信息可以携带当前视频帧的参考帧的信息，如参考帧的标识等，但是由于UPF以及接入网设备均无法解析到应用层，导致接入网设备无法获知当前视频帧的参考帧的信息，进而无法获知参考帧的传输情况，而是直接将当前视频帧传输给终端设备，终端设备在接收到当前视频帧之后，判断当前视频帧的参考帧是否传输成功或解码成功，如果该参考帧传输失败或解码失败，终端设备将会丢弃当前视频帧，这将导致对空口资源的浪费。此外，在网络拥塞情况下，往往存在多个待传输视频帧，那么如何合理地调度空口资源是本申请亟待解决的技术问题。
为了解决上述技术问题，在本申请中，接入网设备可以获得用于确定多个数据集合的重要性和/或关联关系的信息，从而可以根据多个数据集合的重要性和/或关联关系进行空口资源的调度。
应理解的是，由于除了视频帧之间具有依赖关系以外，其他数据，如编码片(video slice)之间、来自多模态业务的数据之间、来自远程控制业务的数据之间等也具有依赖关系，甚至其他形式的数据之间具有依赖关系。基于此，在本申请中，将视频帧、编码片、来自多模态业务的数据或来自远程控制业务的数据等称为数据集合，也可以称为数据单元。每个数据集合包括一个或多个数据包，其中，任一个数据集合中的数据包在应用层具有相同重要性。
实施例一
