Abstract

本公开提供了一种用户设备UE中的方法，包括：检测无线链路中断恢复过程中的异常状况；以及生成指示所述异常状况的信息。

Description

用户设备和相关方法 技术领域
本发明涉及无线通信技术领域，具体地，涉及一种用户设备和相关方法。
背景技术
随着移动通信的快速增长和技术的巨大进步，世界将走向一个完全互联互通的网络社会，即任何人或任何东西在任何时间和任何地方都可以获得信息和共享数据。预计到2020年，互联设备的数量将达到500亿部，其中仅有100亿部左右可能是手机和平板电脑，其它的则不是与人对话的机器，而是彼此对话的机器。因此，如何设计系统以更好地支持万物互联是一项需要深入研究的课题。
为此，在2016年3月举行的第三代合作伙伴计划(3GPP)RAN#64次全会上，提出了新5G无线接入技术的研究课题(参见非专利文献：RP-160671New SID Proposal：Study on New Radio Access Technology)。在该工作项目的描述中，未来新的通信制式的工作频段可扩展至100GHz，同时将至少满足增强的移动宽带业务需求、海量物联网UE的通信需求，以及高可靠性要求的业务需求等，该项目研究工作将于2018年结束。
在该课题的研究中，计划使用波束(beam)/波束赋形(beam forming)来进行信息的传输，具体包括在使用高频进行通信的时候，为了应对高频信道衰落过快的特性，采用发射比较窄的波束。但是，利用较窄的波束来进行信息传输容易受到外界变化的影响，比如手机的旋转，其他物体的遮挡等等。
在采用波束赋形的传输场景下，一旦为UE数据/信息传输服务的有效波束信号变弱或者低于预配置的阈值，数据/信息的传输被中断，这里可以称为无线链路中断/失败。在该情况下，UE将向网络发送相关的请求信息，请求重新配置有效的工作波束，使得中断/失败的链路得以恢复。具体地，当UE检测到采用波束赋形的无线链路发生中断/失败，如果在当前小区内UE能够检测到其他合适的波束(例如具有高于预定阈值的 信号强度)，则UE可以启动波束恢复过程(在本公开的上下文中也称为无线链路中断恢复过程)。该过程可以包括UE向基站发送请求，用于请求重新配置工作波束或者用于请求恢复中断的无线链路。请求中可以指示UE检测到的合适的波束。基站收到请求后，向UE发送响应消息。在响应消息中，基站可以向UE确认其在请求中指示的波束可以作为后续的工作波束，或者基站在响应消息中为UE配置工作波束的。又或者，基站和UE通过进一步的信息交互从而使得UE获得可以工作的波束。当UE获得可以工作的波束后，可以认为波束恢复过程成功结束。
然而，在无线链路中断/失败恢复的过程中，当UE的请求未被网络接受或出现异常时，如何规范UE的行为是需要解决的问题。

在实施例中，当满足以下至少一项时，检测到与无线链路中断恢复过程相关联的随机接入过程失败：达到或超过随机接入的前导序列最大发送次数，以及竞争冲突没有成功解决。

附图说明
通过下文结合附图的详细描述，本发明的上述和其它特征将会变得更加明显，其中：
图1示出了根据本公开实施例的用户设备中的方法的流程图。
图2示出了根据本公开实施例的用户设备的框图。
具体实施方式
下面结合附图和具体实施方式对本发明进行详细阐述。应当注意，本发明不应局限于下文所述的具体实施方式。另外，为了简便起见，省略了对与本发明没有直接关联的公知技术的详细描述，以防止对本发明的理解造成混淆。
下文以NR移动通信系统及其后续的演进版本作为示例应用环境，以支持NR的基站和UE设备为例，具体描述了根据本发明的多个实施方式。然而，需要指出的是，本发明不限于以下实施方式，而是可适用于更多其它的无线通信系统，例如eLTE通信系统，而且可以适用于其他基站和UE设备，例如支持eLTE的基站和UE设备。同时本发明不限于由于波束/波束赋形导致的无线链路中断/失败的场景，还可以用于由于其他原因导致的无线链路中断/失败场景下。
在具体描述之前，先对本发明中提到的若干术语做如下说明。除非另有指出，本发明中涉及的术语都具有下文的含义。

UE         User Equipment用户设备
RLF       Radio Link Failure无线链路失败
NR        New Radio新一代无线技术
LTE       Long Term Evolution长期演进技术

MAC    Medium Access Control媒体接入控制(层)
PHY    physical layer物理层
此外，本文中提到的“无线链路中断(或者失败)恢复过程”，是指使得UE获得/重新获得可以工作的无线链路的过程。由于导致无线链路中断(或者失败)的原因有很多种，其中一种是由于采用了波束赋型，因此，这种情况下，该恢复过程又可以称为“波束恢复过程”。该过程可以举例如下：
当UE检测到采用波束赋形的无线链路出现问题，例如，工作的波束信号强度低于既定的阈值，或者信号强度发生跳变，如果在当前小区内UE能够检测到其他合适的波束，则UE可以启动波束(无线链路中断)恢复过程。该过程可以包括：
UE向基站发送请求(可称为无线链路中断(或者失败)恢复请求，或者波束恢复请求)，用于请求重新配置工作波束或者用于请求恢复中断的无线链路。请求中可以指示UE检测到的合适的波束；
基站收到请求后，向UE发送响应消息(可称为“对UE的无线链路中断/失败恢复请求的响应”，或者“对UE的波束恢复请求的响应”)。在响应消息中，基站可以向UE确认其在请求中指示的波束可以作为后续的工作波束，或者基站在响应消息中为UE配置工作波束的。
又或者，除了前述的请求和响应外，基站和UE通过后续的信息交互从而使得UE获得可以工作的波束。当UE获得可以工作的波束后，可以认为波束恢复过程/无线链路中断恢复过程成功结束。
因此本文所述的无线链路可以是和波束或者波束赋形相关联的，即，该无线链路采用了波束或者波束赋形相关的技术实现传输；无线链路的中断/失败也可以是和波束或者波束赋形相关联的，即可以是由于波束信 号强度低于既定的阈值，或者信号强度发生跳变导致无线链路中断/失败；无线链路的中断/失败恢复过程也可以是和波束或者波束赋形相关联的；即无线链路的中断/失败恢复过程的目的可以是恢复波束，又或者是重新获得可以工作的波束。
图1示出了根据本公开实施例的用户设备UE中的方法100的流程图。方法100可以包括以下步骤：
在步骤S110，检测无线链路中断/失败恢复过程中的异常状况。
在步骤S110中，当满足以下至少一项时，检测到异常状况：
从基站接收到没有可用于UE的波束、波束方向和/或无线链路的指示；
从基站接收到对UE的无线链路中断/失败恢复请求的拒绝信息；
没有从基站接收到或者正确接收到对UE的无线链路中断/失败恢复请求的响应，优选的，UE可以是在预定时间段内没有接收到或者正确接收到所述响应；以及
检测/判断与无线链路中断/失败恢复过程相关联的随机接入过程失败。可选的，该过程可以是UE检测到随机接入过程发生失败，进而判断触发本次随机接入的原因/目的是无线链路中断/失败恢复过程，从而判定无线链路中断/失败恢复过程发生异常或者出现问题；以及
UE发送的无线链路中断/失败恢复请求或者波束恢复请求超过或者等于预定的传输次数。
例如，当满足以下至少一项时，检测到与无线链路中断恢复过程相关联的随机接入过程失败：达到或超过随机接入的前导序列最大发送次数，以及竞争冲突没有成功解决。在这种情况下，由于随机接入过程失败，UE无法向基站发送无线链路中断恢复请求。
在步骤S120，生成指示所述异常状况的信息。
在步骤S120中，该信息可以是在UE的物理层或者MAC层生成，并由UE的物理层或者MAC层向UE的RRC层指示。这一过程还可以被描述为UE的物理层或者MAC层向UE的RRC层指示波束恢复或者无线链路中断/失败恢复发生问题/异常状况。
在实施例中，上述方法还包括：基于所述信息，执行以下至少一项操作：宣布/判断无线链路发生失败；启动定时器，当所述定时器超时， 宣布/判断无线链路发生失败；触发连接重新建立的过程；以及停止正在运行的与链路监测相关的定时器。这些操作可以在RRC层执行。本领域技术人员可以理解，宣布/判断无线链路发生失败可以使得能够触发连接重新建立的过程。

在一个示例中，所述处理器230存储所述处理器220可执行的指令，使得所述用户设备200可以当满足以下至少一项时，检测到异常状况：从基站接收到没有可用于UE的波束、波束方向和/或无线链路的指示；从基站接收到对UE的无线链路中断/失败恢复请求的拒绝信息；在预定时间段内没有从基站接收到对UE的无线链路中断恢复请求的响应；以及检测/判断与无线链路中断恢复过程相关联的随机接入过程失败。
在一个示例中，所述处理器230存储所述处理器220可执行的指令，使得所述用户设备200可以当满足以下至少一项时，检测到与无线链路中断/失败恢复过程相关联的随机接入过程失败：达到或超过随机接入的前导序列最大发送次数，以及竞争冲突没有成功解决。

在一个示例中，所述处理器230存储所述处理器220可执行的指令，使得所述用户设备200可以由物理层或媒体接入控制MAC层向RRC层指示所述信息。
以上关于方法100所描述的所有实施例和示例也适用于UE 200。
