Description

无线承载建立方法及装置 技术领域
本公开涉及通信技术领域,尤其涉及一种无线承载建立方法及装置。
背景技术
车与外界的信息交换(Vehicle to X,简称V2X,也可称为vehicle to everything)是未来智能交通运输系统的关键技术,主要研究基于第三代合作伙伴项目(the 3rd Generation Partnership Project,简称3GPP)通信协议的车辆数据传输方案。V2X通信包括车与车(Vehicle to Vehicle,简称V2V)通信、车与路侧基础设施(Vehicle to Infrastructure,简称V2I)通信以及车与行人(Vehicle to Pedestrian,简称V2P)通信。V2X应用将改善驾驶安全性、减少拥堵和车辆能耗、提高交通效率和车载娱乐信息等。
在V2X通信中,V2V通信是一种和普通无线蜂窝网络通信不太一样的通信方式,在传统的蜂窝网络中,用户设备(user equipment,简称UE)和基站设备进行通信,而在V2V通信中,用户设备直接和用户设备进行通信,用户设备和用户设备之间的链路成为直连链路(sidelink,简称SL)。

具体实施方式
以下将参考附图详细说明本公开的各种示例性实施例、特征和方面。附图中相同的附图标记表示功能相同或相似的元件。尽管在附图中示出了实施例的各种方面,但是除非特别指出,不必按比例绘制附图。
在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外,为了更好的说明本公开,在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解,没有某些具体细节,本公开同样可以实施。在一些实例中,对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述,以便于凸显本公开的主旨。
在5G NR通信系统中,用户设备和基站设备之间的数据传输,是通过建立无线承载和QoS流来实现的。来自上层的数据包,需要映射关联到一个QoS流上,一个QoS流有对应的QoS flow ID(简称QFI),且需要映射和关联到一个无线承载上,而不同的无线承载,可以有不同的传输参数配置,从而满足不同的业务的需求。通常,不同的无线承载通过不同的无线承载标识(无线承载ID)来区别。在5G NR V2X的中,用户设备和用户设备之间的直连链路上,在单播的场景下用户设备和用户设备之间的数据传输可以采用用户设备和基站设备之间的数据传输的QoS模型,也就是,在用户设备和用户设备之间的直连链路上采用数据到QoS流,QoS流到无线承载的映射和关联建立无线承载。
在V2X通信中,相互通信的两个用户设备,建立在直连链路上的QoS流和无线承载,从映射规则和传输参数配置上,是无法保证完全一致的,因为双方用户设备都是根据各自对应的核心网和基站进行QoS流和无线承载的建立的。
在NR通信中,NR无线协议栈分为用户面和控制面两个层面,用户面(User Plane,UP)协议栈即用户数据传输采用的协议簇,控制面(Control Plane,CP)协议栈即系统的控制信令传输采用的协议簇。NR中用户面协议从上到下依次是:SDAP层(Service Data Adaptation Protocol,业务数据适应协议层)、PDCP层(Packet Data Convergence Protocol,分组数据汇聚协议层)、RLC层(Radio Link Control,无线链路层控制协议层)、MAC层(Media Access Control,媒体访问控制层)和PHY(Physical,物理层)。其中,SDAP层用于执行QoS流到无线承载的映射和关联,在上下行数据中标识QFI。PDCP层和RLC层是以无线承载为粒度配置的,不同的无线承载对应其单独的PDCP实体和RLC实体,一个无线承载可以对应一个或多个PDCP实体和RLC实体。MAC层是多个无线承载公用的,用于将多个无线承载所传输的数据复用在一个数据包中交给物理层发送。MAC层在复用不同无线承载的数据时,在不同的 无线承载的数据的MAC子头(sub header)中携带对应的无线承载的逻辑信道标识(logical channel identity,LCID),以表示数据包中的数据来自不同的无线承载。接收设备在接收到数据包之后,根据LCID对数据包解复用,将不同无线承载中的数据分别送至对应的RLC实体和PDCP实体。
在5G NR V2X通信中,RLC层在TM(Transparent Mode,透明)模式、UM(Unacknowledged Mode,非确认)模式、AM(Acknowledged Mode,确认)模式三种模式下进行数据传输。在UM模式下,发送设备通过建立的与接收设备之间的无线承载,向接收设备发送数据包,接收设备无需向发送设备反馈信息。但是在AM模式下,发送设备通过建立的与接收设备之间的无线承载,向接收设备发送数据包,接收设备在接收数据包之后还需向发送设备返回是否成功接收到数据包的RLC状态报告(RLC status report)。发送设备根据从接收设备收到的RLC状态报告,判断是否需要重传的数据包,并在确定需要重传时从重传缓存器(retransmission buffer)中确定需要重传的数据包。
相关技术中,用户设备之间建立无线承载时,存在二者建立了使用相同的LCID的无线承载的情况。也即,第一用户设备建立LCID=1的无线承载,用于向第二用户设备发送数据包1(与第一用户设备的配置信息相对应,这里的数据包1指的来自高层的数据,这里的高层是相对于RLC层来说的,指的是位于RLC层之上的协议层产生的数据,例如来自应用层的应用程序产生数据,或者来自RRC层的RRC信令,在本公开的后续描述中,数据包都指代来自高层的数据),并接收第二用户设备响应数据包1所返回的状态报告1(与第一用户设备的配置信息相对应,RLC状态报告属于由RLC层产生的控制信令,不属于高层的数据);第二用户设备也建立LCID=1的无线承载,用于向第一用户设备发送数据包2(与第二用户设备的配置相对应),并接收第一用户设备响应数据包2所返回的状态报告2(与第二用户设备的配置信息相对应);对应地,在第一用户设备和第二设备中分别设置有两个RLC实体,对应LCID=1的无线承载两个方向的数据传输(也即接收)。在AM模式下,第一用户设备在接收到第二用户设备通过LCID=1的无线承载发送的数据包2,以及第二用户设备发送的响应数据包1的状态报告1时,由于数据包2和状态报告1在各自对应的MAC子头中都是通过LCID=1来标识,第一用户设备MAC层无法判断该将数据包2和状态报告1发送至哪个对应的RLC实体,造成数据接收混淆、错误。
为解决上述问题,可以通过两个方向进行处理,以第一用户设备为例,包括区分数据包2和状态报告1,将其发送至对应的RLC实体;统一数据包2和状态报告1的配置,保证RLC实体可以对数据进行解包;第一用户设备和第二用户设备通过不同无线承载来实现数据包2和状态报告1的接收。以下是本公开提供的几种实现方式示例,本领域技术人员可以结合以下示例以及实际需要对实现方式示例进行修改,本公开对此不作限制。
方式一
图1示出根据本公开一实施例的无线承载建立方法的流程图。如图1所示,该方法应用于第一用户 设备,该方法包括步骤S11至步骤S14。
在步骤S11中,接收第二用户设备发送的第二用户设备的无线承载配置信息。
在步骤S12中,应用第二用户设备的无线承载配置信息。
在步骤S13中,根据第二用户设备的无线承载配置信息,建立(或更新)向第二用户设备发送数据所需的第一无线承载。
在步骤S14中,通过第一无线承载,向第二用户设备发送第一数据。
其中,第一数据可以包括第一用户设备向第二用户设备发送的数据包、第一用户设备响应于第二用户设备发送的数据包所产生的状态报告中的至少一种。
在本实施例中,用户设备可以是各种形式的终端设备,包括接入终端、用户单元、用户站、移动站、移动台(mobile station,建成MS)、远方站、远程终端、移动设备、用户终端、终端设备(terminal equipment)、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称SIP)电话、无线本地环路(Wireless Local Loop,简称WLL)站、个人数字处理(Personal Digital Assistant,简称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处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,简称PLMN)中的终端设备等,本公开对此不作限制。
在本实施例中,应用无线承载配置信息,可以包括根据无线承载配置信息,建立无线承载映射规则。
在一种可能的实现方式中,第二用户设备的无线承载配置信息可以包括以下至少一种:第二用户设备的数据包与QoS流之间的映射和关联规则、第二用户设备的QoS流与无线承载之间的映射和关联规则、第二用户设备的无线承载的传输参数。
在一种可能的实现方式中,应用第二用户设备的无线承载配置信息,可以包括以下至少一项:
根据第二用户设备的数据包与QoS流之间的映射和关联规则,建立第一用户设备的数据包与QoS流之间的映射和关联规则;
根据第二用户设备的QoS流与无线承载之间的映射和关联规则,建立第一用户设备的QoS流与无线承载之间的映射和关联规则;
根据第二用户设备的无线承载的传输参数,确定第二用户设备发送数据所用的无线承载的传输参数。
通过上述方式,可以在第一用户设备和第二用户设备之间统一数据包到QoS流的映射和关联规则、QoS流到无线承载的映射和关联规则、以及无线承载传输参数的配置,保证第一用户设备和第二 用户设备在进行数据传输的过程中采用相同的配置,使得第一用户设备发出的数据包、以及第一用户设备响应于第二用户设备发送的数据包所产生的状态报告均具有相同的配置,二者均可以被RLC实体解包,第二用户设备在接收后无需识别,能够避免数据接收中混淆、错误的发生,保证了用户设备之间通过无线承载进行数据传输的准确性,使二者的数据传输过程不再受无线承载是否为同一个的影响。
在一种可能的实现方式中,在步骤S12之前,该方法还包括:
向基站和/或核心网,转发第二用户设备的无线承载配置信息;
接收基站和/或核心网发送的针对第二用户设备的无线承载配置信息的确认信息。
在该实现方式中,在第一用户设备自身不能够单独进行无线承载映射规则和无线承载的建立,需要向基站或核心网进行指示时,第一用户设备在接收到无线承载配置信息之后,需先向基站和/或核心网转发,并在得到基站或核心网的确认之后,再进行无线承载配置信息的应用。那么,在第一用户设备自身能够单独进行无线承载的建立时,则无需向基站或核心网转发确认。
在本公开实施例中,基站(base station,简称BS),也可称为基站设备,是一种部署在无线接入网(RAN)用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(英文:base transceiver station,简称BTS),3G网络中提供基站功能的设备包括节点B(NodeB),在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB,eNB),在无线局域网络(wireless local area networks,简称WLAN)中,提供基站功能的设备为接入点(access point,简称AP),5G新无线(New Radio,简称NR)中的提供基站功能的设备gNB,以及继续演进的节点B(ng-eNB),其中gNB和终端之间采用NR技术进行通信,ng-eNB和终端之间采用E-UTRA(Evolved Universal Terrestrial Radio Access)技术进行通信,gNB和ng-eNB均可连接到5G核心网。本申请实施例中的基站还包含在未来新的通信系统中提供基站功能的设备等。
在本公开实施例中,核心网可以是演进型分组核心网(evolved packet core,简称EPC)、5G Core Network(5G核心网),还可以是未来通信系统中的新型核心网。5G Core Network由一组设备组成,并实现移动性管理等功能的接入和移动性管理功能(Access and Mobility Management Function,AMF)、提供数据包路由转发和QoS(Quality of Service)管理等功能的用户面功能(User Plane Function,UPF)、提供会话管理、IP地址分配和管理等功能的会话管理功能(Session Management Function,SMF)等。EPC可由提供移动性管理、网关选择等功能的MME、提供数据包转发等功能的Serving Gateway(S-GW)、提供终端地址分配、速率控制等功能的PDN Gateway(P-GW)组成。

图2示出根据本公开另一实施例的无线承载建立方法的流程图。如图2所示,该方法应用于第一用 户设备,该方法包括步骤S21至步骤S23。
在步骤S21中,接收第二用户设备发送的当前已经建立的第二无线承载的逻辑信道标识;
在步骤S22中,将第二无线承载的逻辑信道标识发送至基站和/或核心网,以使基站和/或核心网为第一用户设备建立第三无线承载,第三无线承载的逻辑信道标识与第二无线承载的逻辑信道标识不同;
在步骤S23中,通过第三无线承载,向第二用户设备发送第二数据,
其中,第二数据可以包括第一用户设备向第二用户设备发送的数据包。
在一种可能的实现方式中,第二无线承载包括采用确认模式(也即AM模式)的无线承载。
在该实现方式中,第二无线承载是第二用户设备已经建立的、用于向第一用户设备发送数据包所用的无线承载。这样,可以保证基站和/或核心网为第一用户设备所建立的第三无线承载的逻辑信道标识与第二无线承载的逻辑信道标识不同。
在一种可能的实现方式中,该方法还包括:
通过第二无线承载,向第二用户设备发送第三数据,
其中,第三数据可以包括第一用户设备响应于第二用户设备通过第二无线承载发送的数据包所产生的状态报告。
通过这种方式,第一用户设备可以通过第三无线承载向第二用户设备发送第二数据。第一用户设备可以在通过第二无线承载接收第二用户设备发送的数据包后,通过第二无线承载向第二用户设备返回状态报告(也即第三数据)。这样,将第一用户设备的数据包发送过程与状态报告的发送过程分别通过不同的无线承载进行,不会造成用户设备的数据接收混乱。
在一种可能的实现方式中,该方法还可以包括:在LCP(Logical channel prioritization,逻辑信道优先级)过程中,当第三无线承载与第二无线承载所对应的优先级别相同时,优先将资源分配给第二无线承载(也即第三数据),也即优先通过第二无线承载向第二用户设备发送第三数据。
在该实现方式中,根据数据传输任务类型、传输时间、传输量等的不同,不同的无线承载所对应的优先等级不同,优先等级高的无线承载可以优先对其分配传输资源。在第二无线承载和第三无线承载的优先级别相同时,第三数据的优先级别高于第二数据,第一用户设备优先分配资源给第三数据。
方式三
图3示出根据本公开一实施例的无线承载建立方法的流程图。如图3所示,该方法应用于第一用户设备,该方法包括步骤S31至步骤S33。
在步骤S31中,接收第二用户设备通过第四无线承载发送的第四数据;
在步骤S32中,对第四数据进行区分,得到区分结果;
在步骤S33中,根据区分结果,对第四数据进行处理,
其中,第四数据包括第二用户设备向第一用户设备发送的数据包、第二用户设备响应于第一用户设备通过第四无线承载发送的数据包所产生的状态报告中的至少一种。
在该实现方式中,第二用户设备在发送第四数据之前,第二用户设备和第一用户设备之间先建立第四无线承载,以进行数据传输。其中,第二用户设备和第一用户设备之间先建立第四无线承载包括:
第二用户设备建立逻辑信道标识为M的第四无线承载用于向第一用户设备发送数据包(数据包a)和/或用于接收第一用户设备发送的响应于第二用户设备通过第四无线承载发送给第一用户设备的数据包(也即数据包a)的状态报告(状态报告a),并建立对应的RLC实体。另一方面,第一用户设备也建立逻辑信道标识为M的第四无线承载用于接收第二用户设备发送的数据包(也即数据包a)和/或用于发送响应于第二用户设备通过第四无线承载发送给第一用户设备的数据包(也即数据包a)的状态报告(也即状态报告a),并建立对应的RLC实体。
并且,第一用户设备还将第四无线承载用于向第二用户设备发送数据包(数据包b)和/或接收第二用户设备发送的响应于第一用户设备通过第四无线承载发送给第二用户设备的数据包(也即数据包b)的状态报告(状态报告b),并建立对应的RLC实体,第二用户设备还会将第四无线承载用于接收第一用户设备发送的数据包(也即数据包b)和/或用于发送响应于第一用户设备通过第四无线承载发送给第二用户设备的数据包的状态报告(也即状态报告b),并建立对应的RLC实体。
本公开所描述的第四无线承载是指在第一用户设备和第二用户设备中具有相同LCID的无线承载。那么,在第四无线承载在第一用户设备和第二用户设备中的LCID相同、且无线承载ID不同时,可以认为该第四无线承载为两个不同的无线承载。在第四无线承载在第一用户设备和第二用户设备中的LCID相同、且无线承载ID也相同时,可以认为该第四无线承载为一个无线承载。
第一用户设备中用于发送数据包b和接受状态报告b的RLC实体为同一RLC实体,第一用户设备中用于接收数据包a和发送状态报告a的RLC实体为同一RLC实体,第一用户设备中用于发送数据包b和发送状态报告a的RLC实体可能相同也可能不相同,对应的,第一用户设备中用于接收数据包a和接受状态报告b的RLC实体可能相同也可能不相同。
数据传输的过程包括以下至少之一:第一用户设备通过第四无线承载接收第二用户设备发送的数据包a(也即第四数据中的一种);第一用户设备通过第四无线承载向第二用户设备发送响应于数据包a的状态报告a;第一用户设备通过第四无线承载向第二用户设备发送数据包b;第一用户设备通过第四无线承载接收第二用户设备发送的响应于数据包b的状态报告b(也即第四数据中的一种)。
在该实现方式中,第一用户设备在区分出第四数据之后,将不同的数据发送至其对应的RLC实体或RLC子层进行处理。
在一种可能的实现方式中,对第四数据进行区分,得到区分结果,可以包括以下任意一项:
第一用户设备的MAC层根据第四数据的RLC包头,对第四数据进行区分,得到区分结果;
第一用户设备的MAC层根据第四数据的MAC子头中携带的指示信息,对第四数据进行区分,得到区分结果;
第一用户设备的RLC层中的第一RLC子层根据第四数据的RLC包头,对第四数据进行区分,得到区分结果。
在该实现方式中,在第一用户设备的配置信息与第二用户设备的配置信息没有统一的情况下,两用户设备发出的数据包的配置是不同的,若在AM模式下,二者均采用同一无线承载进行数据主动传输以及状态报告的反馈时,以第一用户设备所接收到的第四数据为例,对方式三进行说明。
由于第二用户设备在发送不同的数据时,不同数据的RLC包头的“D/C”域并不相同,该“D/C”域占用1比特,用于指示该数据是第二用户设备向第一用户设备发送的数据包(也即数据包a),或是第二用户设备响应于第一用户设备发送的数据包所产生的状态报告(也即状态报告b)。第一用户设备的MAC层基于不同的RLC包头可以区分第四数据。
但由于并不是所有用户设备均能够识别数据的RLC包头。因此,可以控制第二用户设备在发出第四数据之前,在MAC子头中通过添加指示信息对不同的数据进行标记。这样,第一用户设备的MAC层可以通过识别MAC子头的指示信息对第四数据进行区分。
图4示出根据本公开一实施例的无线承载建立方法中RLC层的分层示意图。如图4所示,还可以对第一用户设备的RLC层进行分层,分为一个或多个RLC子层,其中,第一RLC层可以用于对第四数据的RLC包头进行识别,例如通过“D/C”域来区分,以对第四数据进行区分。RLC层中的第二RLC子层可以用于实现RLC层的其余功能。
在一种可能的实现方式中,该方法还可以包括:
在LCP(Logical channel prioritization,逻辑信道优先级)过程中,当通过第四无线承载向第二用户设备发送数据包以及发送响应于第二用户设备发送的数据包所产生的状态报告、且向第二用户设备发送的数据包和向第二用户设备发送的响应于第二用户设备发送的数据包所产生的状态报告的优先级相同时,优先分配资源给通过第四无线承载向第二用户设备发送的响应于第二用户设备发送的数据包所产生的状态报告。
在该实现方式中,由于第一用户设备和第二用户设备均通过逻辑信道标识为M的无线承载进行数据发送,以第一用户设备为例,存在状态报告a和数据包b同时参与组包的情况。那么,第一用户设备优先分配资源给状态报告a,若资源还有剩余,则分配给数据包b。
本公开实施例所提供的无线承载建立方法,适用于5G(5Generation)通信系统,还可适用于4G、 3G通信系统,还可适用于未来新的各种通信系统,例如6G、7G等。且也适用于不同的网络架构,包括但不限于中继网络架构、双链接架构、V2X架构等架构。
