具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或 单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同 于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
长期演进(Long Term Evolution，LTE)系统支持副链路(sidelink，或译为侧链路，边链路)，如图1所示，sidelink用于用户设备(User Equipment，UE)之间不通过网络设备进行直接数据传输，其中，Uplink为上行传输，Downlink为下行传输。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格服务质量(Quality of Service，QoS)需求的高级V2X业务需要通过新空口(New Radio，NR)sidelink支持。
5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，但目前的NR系统只支持基站与终端间的接口，尚不支持终端之间直接通信的sidelink接口。
Sidelink链路接口又可以称作PC5接口。目前的sidelink传输主要分为：广播(broadcast)，组播(groupcast)，单播(unicast)几种传输形式。单播顾名思义就是一对一(one to one)的传输，组播为一对多(one to many)的传输，广播也是one to many的传输，但是广播并没有UE属于同一个组的概念。目前sidelink单播和组播通信支持物理层混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈机制。
Sidelink UE的资源分配模式总共分为两类：
1)基站调度模式(Mode 1):BS schedules SL resource(s)to be used by UE for SL transmission(s)，即由基站(基站)控制并为每个UE分配资源。
2)UE自主模式(Mode 2):UE determines,i.e.BS does not schedule,SL transmission resource(s)within SL resources configured by BS/network or pre-configured SL resources，即由每个UE自主选择资源。
Uu接口中，由于下列原因可以触发无线链路失败(Radio Link Failure， RLF)：物理层上报链路差，并且在规定时长内无法恢复；媒体接入控制(Media Access Control，MAC)指示随机接入问题；无线链路控制(RadioLinkControl,RLC)确认(AM)达到了最大重传次数。
但Uu接口的无线链路失败处理方式，并不适用于sidelink接口，而sidelink接口无线链路失败之后的处理方式，目前没有进一步的解决方案。
本公开实施例提供了一种无线链路失败处理方法及装置，能够对失败的无线链路进行及时的释放和回收资源处理。
本公开实施例提供了一种无线链路失败处理方法，应用于第一终端，如图2所示，包括：
步骤101：检测到与第二终端之间的无线链路失败；
步骤102：向自身归属基站上报无线链路失败的指示消息，所述指示消息包括以下至少一种信息：

无线链路失败指示；
所述无线链路失败的原因。
本实施例中，第一终端在检测到与第二终端之间的无线链路失败后，向自身归属的第一基站上报无线链路失败的指示消息，这样可以使得第一终端归属的第一基站及时了解无线链路的失败并进行处理，可以对失败的无线链路进行及时的释放和回收资源处理，避免了资源浪费，从而达到更好的控制无线链路数据传输的效果，得到更好的用户体验。
具体地，无线链路可以为PC5链路，当然，无线链路并不局限为PC5链路，还可以为其他类型的无线链路。
可选地，检测到与第二终端之间的无线链路失败之前，所述方法还包括以下任一种：
接收所述第二终端的第一通知消息，所述第一通知消息包括所述第二终端的归属基站的信息；
向所述第二终端发送第二通知消息，所述第二通知消息包括自身归属基站的信息。
这样第一终端和第二终端可以在无线链路失败之前，交互各自的归属基 站的信息，使得对方获知自身的归属基站的信息。
另外，在第一终端的归属基站发生变化后，第一终端还要向所述第二终端发送第三通知消息，所述第三通知消息包括自身归属基站的信息，这样可以使得第二终端及时了解到第一终端最新的归属基站。
第一通知消息并不局限于仅包括第二终端的归属基站的信息，还可以包括所述第二终端的身份标识和/或所述无线链路的信息；所述第二通知消息并不局限于仅包括第一终端的归属基站的信息，还可以包括所述第一终端的身份标识和/或所述无线链路的信息。

下面结合附图以及具体的实施例对本公开的无线链路失败处理方法进行进一步介绍。
实施例一
本实施例中，在无线链路失败后，终端向基站上报无线链路失败消息。
Uu接口中，由于下列至少一种原因可以触发无线链路失败：
物理层持续上报链路差，并且在规定时长内无法恢复；
MAC指示随机接入问题；
RLC AM达到了最大重传次数。
对于sidelink单播(unicast)UE来说，由于是UE1(即第一终端)和UE2(即第二终端)之间一对一建立链路，也需要对链路质量检测，当链路不再满足工作条件时，认为发生了无线链路失败。Sidelink接口目前没有MAC层的随机接入过程，因此无法根据MAC指示随机接入问题触发无线链路失败，但sidelink unicast配置了AM模式时，如果达到了最大重传次数，则RLC协议无法继续，也需要触发RLF。
因此，在sidelink可以存在以下两种触发RLF的机制：
一种是物理层持续上报链路差，并且在规定时长内无法恢复；另一种是 RLC AM达到了最大重传次数上报。其中，前一种触发方式一般是接收端触发，因为在sidelink接口没有周期性或者持续发送参考信号，物理层的质量测量都是基于数据所伴随的参考信号进行，那么只有接收数据的一方才可以进行链路质量测量，如果是单向业务传输的话，则只有一侧UE可以测量，如果是双向业务传输的话，则两侧UE都可以测量。而第二种触发方式是发送端的行为，只能由发送端进行触发，当两侧都有业务发送时，则两侧都可以作为发送端触发。
当RLF触发之后，说明sidelink链路无法再继续，那么检测到RLF的UE可以将情况上报给基站，上报信息中可以包含以下至少一种：
无线链路标识，例如V2X link ID或者目的(destination)ID等；
RLF指示，用以表示是一个RLF上报，可以由信令名称或者通用信令中的显式域来指示；
无线链路失败原因，例如物理层还是RLC触发等。
当基站接收到RLF上报之后，将该无线链路对应的资源进行释放，例如专用sidelink pool资源，周期性配置sidelink资源，用于辅助sidelink的Uu接口资源等。
实施例二
本实施例中，无线链路两端的UE交互各自的信息。
Sidelink unicast两端的UE，可以在sidelink链路维持的期间，交互UE的归属基站信息，还可以交互UE身份信息和/或无线链路信息。
一具体示例中，UE在sidelink建立或者配置时，就互相交互自身归属基站的信息，也可以交互UE的身份信息和/或无线链路信息；其中，归属基站信息对于连接态UE来说可以是Pcell(主小区)的小区标识cell ID，对于空闲态(Idle)/非激活态(inactive)UE来说，就是驻留小区的小区标识；UE的身份信息和无线链路信息，可以是V2X link ID，destination L2ID，连接态的小区无线网络临时标识(Cell-RadioNetworkTemporaryIdentifier，CRNTI)，Inactive Resume ID等，只要能够让其它基站找到UE对应的link的对端UE即可。
其中，上述交互信息的过程可以和能力上报或者链路配置合并进行，或 者并行进行。
在sidelink unicast通信的过程中，由于UE处于移动状态，因此UE的归属基站是变化的，例如切换和小区重选的发生，这时需要向对端UE更新自身归属基站的信息，即归属基站变化时，触发向对端UE使用PC5无线资源控制(radio resource control,RRC)信令进行归属基站变化上报，携带最新的归属基站信息，可选地，还可以携带UE的身份信息和/或无线链路信息，用以标识UE；为了获得最新的对端UE的归属信息，对于sidelink RRC信令来说，需要在sidelink链路建立初始时就进行信息交互以及在信息变化时实时交互更新后的信息，因为一旦发生了RLF，sidelink链路失败，交互信息将无法成功。
当sidelink两端的UE通过RRC信令交互得到对端UE的归属基站信息或者更新的归属基站信息之后，UE将其上报给自身的归属基站，进行存储，作为UE的上下文信息；或者当sidelink两端的UE通过RRC信令交互得到最新的对端UE的归属基站信息、UE的身份信息和/或无线链路信息时，先存储在UE，在需要上报的时候，例如触发了RLF后，再和RLF一起上报给归属基站，便于归属基站对对端UE的资源进行释放，这样可以节省Uu接口的上报和更新过程，仅在上报RLF的同时上报即可。
实施例三
本实施例中，第一基站通知第二基站无线链路失败。
Sidelink unicast两端UE的数据量有可能是不对等的，如果一个方向数据量比较多，那么测量机会也会比较多，另一个方向数据量较少，测量机会也会比较少。因此当发生RLF时，很有可能仅是一端的UE先检测出来，而另一端的UE还没有检测到。在这种情况下，已经检测到RLF的一端UE，可以通知另一方进行资源的释放，能够提升资源的利用率。
具体地，如图4所示，包括以下步骤：
步骤301：UE1(即第一基站)进行sidelink链路检测；
步骤302：当UE1检测到RLF时，将RLF上报给自己的归属基站gNB1(即第一基站)；
步骤303：gNB1进行sidelink资源释放；
步骤304：gNB1向gNB2(即第二基站)通知RLF；
由于归属基站gNB1里存储有对端UE 2的归属基站gNB2的身份信息和/或无线链路信息，因此归属基站gNB1可以通过Xn/X2接口向gNB2发送sidelink RLF指示信息；其中指示信息需要携带sidelink RLF指示，UE 2指示，或者是sidelink链路的link ID、destination ID指示等，便于gNB2找到对应的UE2和/或无线链路信息，进行正确的释放处理；
步骤305：gNB2进行sidelink资源释放；
基站gNB2在接收到来自gNB1的sidelink RLF信息之后，根据携带的信息，找到对应的UE2和/或无线链路，对已经发生无线链路失败的sidelink链路资源进行释放；
步骤306：gNB2向UE2(即第二终端)发送释放通知。
基站gNB2还可以对UE2进行释放，指示已经发生了RLF，sidelink通信可以结束。
一具体示例中，作为sidelink接收端的UE1，通过接收数据中的参考信号测量，判断满足了触发RLF的条件，则上报给自己的归属基站gNB1,由于UE1和UE2之间可能存在多条链路，因此需要指示是哪条sidelink链路发生了失败，还可以指示对端UE的信息，包括归属基站gNB2信息以及UE2的身份信息、无线链路信息等，gNB1得到RLF上报，可以释放本侧的关于该sidelink的资源，并向对端UE2的归属基站gNB2发送Xn和/或X2消息，通知该sidelink链路RLF，基站gNB2接收到该消息后，通过消息里携带的UE2的信息以及无线链路的信息，可以释放相应的资源，并通过Uu接口向UE2发送sidelink链路释放消息，结束sidelink通信，进行资源回收。当两个UE归属于同一个基站时，则可以节省接口信令，直接进行对端UE链路和资源的释放。
进一步地，UE在上报给自己归属基站发生RLF时，也可以携带一些额外信息，例如对端UE是否是发送端，因为只有发送端UE需要释放资源，对端UE是非发送端UE的话，可以不需要通过Xn和/或X2消息通知对端进行无线链路释放；或者只有在对端UE是发送端，需要通知释放对端UE的资源时，才携带对端UE的归属基站信息，以此来隐式的指示是否需要通过Xn和 /或X2消息通知对端进行无线链路释放。
