无线链路失败上报方法、信息交互方法及设备
相关申请的交叉引用
本申请主张在2018年9月25日在中国提交的中国专利申请No.201811117094.5的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种无线链路失败上报方法、信息交互方法及设备。
背景技术
在长期演进(Long Term Evolution，LTE)***中，UE会进行无线链路失败(Radio Link Failure，RLF)的监测，导致无线链路失败的原因有多种，比如：
1、T310定时器(timer)过期；
2、T312timer过期；
3、收到媒体接入控制层(Media Access Contral，MAC)层指示的随机接入问题且任意一个timer(T300、T301、T304、T311)都未运行；
4、收到无线链路控制(Radio Link Contral，RLC)层指示自动重传请求(Automatic Repeat-reQuest，ARQ)达到最大重传次数。
LTE***为了支持移动鲁棒性优化，在Rel-9(第9版本)引入了终端无线链路失败上报机制，通过在RRC连接重建完成(RRC Connection Re-establishment Complete)消息携带指示表明有RLF信息需要上报。Rel-10(第10版本)中对无线链路失败上报的机制和内容进行了增强，在RRC连接建立完成(RRC Connection Setup Complete)消息和RRC重配置完成(RRC Reconfiguration Complete)消息中增加了表明有RLF上报的指示，此外在内容中增加了位置信息、时间信息以及失败种类等信息。
另一方面，国际电信联盟(ITU)定义了第五代移动通信技术(The 5th Generation Mobile Communications，5G)的三大类应用场景，并提出了相比 4G更具挑战性的关键指标能力，要求支持100Gbps+的峰值速率和更低空口时延(增强移动宽带(eMBB)4ms，低时延高可靠连接(URLLC)0.5ms)。为了实现相比LTE快几倍的峰值速度，考虑到相关技术中的无线通信频谱(低于6GHz)资源严重不足的现状，5G将很可能会利用相比相关技术中的LTE使用的频谱高很多的频谱资源(例如毫米波频段在10GHz以上)进行无线通信，为了增强覆盖，5G将使用波束赋形的技术。
终端RLF信息的上报在网络优化中具有重要作用，比如用于移动性优化，覆盖优化等，但相关技术中的RLF报告中还未包含5G中引入的波束(beam)和增强上行载波(Supplementary UPLink，SUL)的相关信息。

以因LTE过迟切换发生无线链路失败为例，请参阅图1，无线链路失败上报的流程为：1.无线链路失败在切换之前发生在源小区(源基站的)，UE(终端)向目标基站发送无线资源控制(Radio Resource Control，RRC)连接重建请求(RRC Connection Reestablishment Request)消息；2.目标基站向UE发送RRC连接重建(RRC Connection Reestablishment)消息；3.UE向目标基站发送RRC连接重建完成(RRC Connection Reestablishment Complete)消息，携带表明有RLF上报的指示；4.目标基站向UE发送终端信息请求(UE Information Request)消息，携带RLF上报(report)请求；5.UE向目标基站发送终端信息应答(UE Information Response)，携带RLF报告(RLF report)，包含有RLF信息；6.目标基站向源基站发送RLF指示(RLF indication)。
目标3GPP协议中，上报的无线链路失败信息中包含的主要内容如下表所示：
表1上报的无线链路失败信息中包含的主要内容
Figure PCTCN2019107969-appb-000001
Figure PCTCN2019107969-appb-000002
上表中，无线链路失败信息并不包含5G NR中引入的波束的相关信息和增强上行链路(SUL)的相关信息。因此，为解决这一技术问题，本公开实施例一提供了一种无线链路失败上报方法，请参阅图2，该方法应用于终端，包括以下步骤：
步骤11：向网络侧设备上报无线链路失败信息，所述无线链路失败信息包括波束的信息和/或上行载波的信息。
本公开实施例中，终端向网络侧设备上报的无线链路失败信息中，包含了波束的相关信息和/或上行载波的相关信息。从而，为网络优化(包括移动性优化和覆盖优化等)提供了更多的信息。其中，上行载波包括上行链路载波和增强上行链路载波，波束和增强上行链路载波(SUL)是5G NR中引入的。
具体地，所述网络侧设备可以是基站，终端在一个基站下的小区内发生无线链路失败后，可能会向另一个基站的小区发起RRC重建，或者，在进入空闲态后直接向另一个基站的小区发起RRC建立，并最终与另一基站建立了RRC连接。与终端最终建立了RRC连接的基站，在接收到终端上报的无线链路失败信息后，会转发(通过RLF indication)给发生无线链路失败的基站。
下面举例说明上述无线链路失败上报方法。
其中一种可选的具体实施方式中，所述波束的信息包括以下至少之一：
发生无线链路失败的服务小区的波束的标识；
所述服务小区的波束的测量信息；
