本申请主张在2018年8月7日在中国提交的中国专利申请号No.201810892074.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种小区波束失败处理方法、移动通信终端和网络侧设备。
背景技术
未来5G(5 Generation,第五代)移动通信系统中，为达到下行链路传输速率20Gbps，上行链路传输速率10Gbps的目标，高频通信和大规模天线技术将会被引入。高频通信可提供更宽的系统带宽，天线尺寸也可以更小，更加有利于大规模天线在基站和UE(User Equipment,用户设备)中部署。
在5G通信系统中，由于链路的脆弱性，在高频通信中会经常出现波束失败的情况。目前检测波束失败是通过计数器和计时器中的至少一项来统计波束失败实例(beam failure instance)，以实现波束失败检测。其中，目前波束失败恢复过程包括：波束失败检测，新候选波束识别，波束失败恢复请求发送，以及终端监测波束失败恢复请求的基站响应。也就是说，在目前的波束失败处理中，只要波束失败，则进行波束失败恢复。但是，目前的波束失败恢复存在耗费时间较长，导致终端并不能及时恢复与小区的连接的问题。
发明内容
本公开实施例提供一种小区波束失败处理方法、移动通信终端和网络侧设备，以解决相关技术中的波束失败恢复耗费时间较长，导致终端并不能及时恢复与小区的连接的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提供了一种小区波束失败处理方法，用于移动 通信终端，包括：
在目标小区执行检测操作，所述检测操作至少包括波束失败检测；
根据检测结果，在目标小区执行加快波束失败处理的第一操作。
第二方面，本公开实施例提供了一种小区波束失败处理方法，用于网络侧，包括：
接收移动通信终端依据检测结果发送的指示信息；所述检测结果至少包括：针对目标小区进行的波束失败检测的结果；
根据指示信息执行加快波束失败处理的第二操作。
第三方面，本公开实施例提供了一种移动通信终端，包括：
检测模块，用于在目标小区执行检测操作，所述检测操作至少包括波束失败检测；
第一执行模块，用于根据检测结果，在目标小区执行加快波束失败处理的第一操作。
第四方面，本公开实施例提供了一种网络侧设备，包括：
接收模块，用于接收移动通信终端依据检测结果发送的指示信息；所述检测结果至少包括：针对目标小区进行的波束失败检测的结果；
第二执行模块，用于根据指示信息执行加快波束失败处理的第二操作。
第五方面，本公开实施例提供了一种移动通信终端，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面中所述的小区波束失败处理方法中的步骤。
第六方面，本公开实施例提供了一种网络侧设备，包括：存储器、处理器、收发机及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第二方面中所述的小区波束失败处理方法中的步骤。
第七方面，本公开实施例提供了一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现如第一方面中或第二方面中所述的小区波束失败处理方法中的步骤。
相关技术中的波束失败检测过程中，物理层会在一定的条件满足时，向 媒体接入控制(Media Access Control，MAC)层指示一个波束失败实例，而MAC层通过计数物理层周期性指示的波束失败实例来判断是否波束失败。如在MAC层，会启动一个定时器和计数器来执行波束失败判断。定时器计时结束前如果收到一个实例，则计数器加1并重启计时器，否则定时器计时结束前如果没有收到一个实例，则计数器重置。当计数器达到预设次数时，则确定发生波束失败事件。
而这种物理层周期性上报检测事件，而MAC层结合计数器和计时器对周期性上报事件进行管理来判断是否发生波束失败事件的方式，由于在失败检测阶段耗时较长，因此也会导致波束从失败中恢复的时间较长。
而本公开具体实施例中，在目标小区执行至少包括波束失败检测的检测操作，根据物理层的检测结果，在目标小区执行能够加快波束失败处理的第一操作，如直接发起波束失败恢复、直接触发无线链路失败流程、直接触发失败实例上报、上报网络侧等。这样，终端能够在目标小区检测到波束失败时，直接执行第一操作，使得终端能够尽快从波束失败中恢复。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。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。
请参加图1，图1是本公开实施例提供的一种小区波束失败处理方法的流程图，该方法用于移动通信终端，如图1所示，包括以下步骤：
步骤101、在目标小区执行检测操作。
需要说明的是，所述移动通信终端可以是如手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备；本公开实施例中并不限定移动通信终端的具体类型。移动通信终端处于至少一个小区的覆盖范围内，且可以是与至少一个小区建立连接。
本公开实施例中，所述目标小区可以是如下小区中的一个，例如可以是辅小区(Secondary Cell，SCell)，或者可以是主小区；其中，Scell可以是载波聚合(Carrier Aggregation，CA)场景中的Scell，或者可以是双连接(Dual Connectivity，DC)架构中主小区组(Master Cell Group，MCG)或者辅小区组(Secondary Cell Group，SCG)中的Scell。而上述主小区可以是CA场景中的主小区(Primary Cell，PCell)，或者可以是DC架构中MCG中的PCell，或者可以是SCG中的主辅小区(Primary Secondary Cell，PsCell)，或者可以是特殊小区(Sepcial Cell，Spcell)，其中，PCell和PsCell均可以称作Spcell。另外，Scell和主小区可以对应同一个基站，或者在一些场景中，Scell和主小区也可以对应不同的基站，对此不作限定。
该步骤中，所述检测操作至少包括波束失败检测。本公开具体实施例的波束失败检测可以使用相关技术中任意的波束失败检测方案进行检测，而同时，本公开具体实施例提出一种新的基于参考信号进行波束失败检测的方案，说明如下。
本公开具体实施例中，所述波束失败检测可以为：根据在目标小区上对目标参考信号进行检测得到的测量性能信息，确定是否检测到波束失败事件。
其中，所述测量性能信息可以是误块率(Block Error Ratio，BLER)，当对目标参考信号检测得到的BLER高于预设阈值，则确定检测到波束失败事件。例如，可以是在目标小区上对所有能够检测到的参考信号进行检测，且当所有的目标参考信号检测得到的测量性能信息不满足要求，则确定检测到波束失败事件；或者，也可以是在目标小区上对所有能够检测到的参考信号进行检测，当其中预设数量的目标参考信号检测得到的测量性能信息不满足要求，则确定检测到波束失败事件；或者还可以是，对为目标小区配置的预设个数的参考信号进行检测，当预设个数的参考信号检测得到的测量性能信息不满足要求，确定检测到波束失败事件。
此外，测量性能信息还可以是RSRP，RSRQ或者SINR，当这些测量性能低于预设门限值时，则确定检测到波束失败事件。
需要说明的是，所述目标参考信号包括如下参考信号中的至少一项：
为目标小区配置的用于波束失败检测的参考信号；
为目标小区配置的用于波束失败事件的参考信号；
为目标小区配置的用于波束管理的参考信号；
目标小区上能够检测到的参考信号；
为目标小区配置的预设个数的参考信号。
可以理解地，当所述目标参考信号为上述参考信号中的任意一项时，只要在目标小区上检测到该目标参考信号的测量性能信息不满足要求，则确定检测到波束失败事件。当目标小区上配置的所述目标参考信号为上述参考信号中的至少两项的集合时，例如所述目标参考信号包括为目标小区配置的用于波束失败检测的参考信号、为目标小区配置的用于波束失败事件的参考信号以及为目标小区配置的用于波束管理的参考信号时，可以是当检测得到的上述三项参考信号的测量性能信息都不满足要求时，则确定检测到波束失败事件，或者也可以是上述三项参考信号中的任意两项的测量性能信息不满足要求时，则确定检测到波束失败事件。本公开实施例中还可以是包括参考信号的其他组合方式，在此不做赘述。
步骤102、根据检测结果，在目标小区执行加快波束失败处理的第一操作。
其中，所述检测操作至少包括波束失败检测，也就是根据波束失败检测的检测结果，在目标小区执行加快波束失败处理的第一操作。
而本公开具体实施例中，在目标小区执行至少包括波束失败检测的检测操作，根据物理层的检测结果，在目标小区执行能够加快波束失败处理的第一操作，如直接发起波束失败恢复、直接触发无线链路失败流程、直接触发失败实例上报、上报网络侧等。这样，终端能够在目标小区检测到波束失败时，直接执行第一操作，使得终端能够尽快从波束失败中恢复。
本公开上述的实施例中以检测操作包括波束失败检测为例进行的说明，但考虑到在波束失败时，相关技术提供了波束失败恢复的操作选项，因此，本公开具体实施例中，进一步预测波束失败恢复是否能够成功，并依据波束失败恢复的成功机会来决定下一步是否进行执行加快波束失败处理的第一操作。
即：本公开实施例中，所述检测操作还包括波束失败恢复条件检测，所述步骤102具体为：
在波束失败检测检测到波束失败事件，且波束失败恢复条件不成立时，在目标小区执行加快波束失败处理的第一操作。
也就是说，在目标小区执行检测操作，所述检测操作至少包括波束失败检测以及波束失败恢复条件检测；可以是当检测到波束失败事件，则执行对波束失败恢复条件的检测，并且当检测到波束失败恢复条件不成立时，也就是不满足进行波束失败恢复的条件，则在目标小区执行加快波束失败处理的第一操作。
本公开具体实施例中，设置了一个波束失败恢复条件，通过该波束失败恢复条件的检测来决策后续的操作。该波束失败恢复条件是用于预测波束失败恢复是否能够成功的条件，本公开实施例中，所述波束失败恢复条件包括如下条件中的至少一项：
目标小区是否有可用的候选波束；
目标小区是否具有执行波束失败恢复流程的可用资源；
目标小区是否发生对应于检测到的波束失败事件的波束失败恢复失败事件。
对这些条件具体说明如下。
波束失败恢复能够成功的条件是：终端能够切换到新的满足要求的波束上去，而当目标小区没有配置候选波束，或者配置了候选波束，但候选波束的参考信号的测量性能不满足要求，此时即使执行波束失败恢复流程也无法成功，因此，当目标小区没有可用的候选波束时，则可以认为波束失败恢复条件不成立。
波束失败恢复需要一定的资源来发起。因此，本公开具体实施例中，该波束失败恢复条件也可以是：目标小区是否具有执行波束失败恢复流程的可用资源，当不具有执行波束失败恢复流程的可用资源时则认为波束失败恢复条件不成立，此时则需要执行加快波束失败处理的第一操作。
目前依据相关规范，波束失败恢复可以附着于一定的流程，如目前可以通过非竞争随即接入(Contention-Free Random Access，CFRA)流程或竞争随机接入(Contention Based Random Access，CBRA)流程来实现波束失败恢复。
因此，本公开实施例中，所述目标小区是否具有执行波束失败恢复流程的可用资源具体包括如下条件中的至少一项：
所述目标小区是否配置有用于非竞争随即接入CFRA流程的第一资源；
所述目标小区是否配置有第二资源，所述第二资源为用于支持波束失败恢复的CFRA流程的资源；
所述第二资源上的参考信号是否满足测量性能要求；
所述目标小区是否配置有用于竞争随即接入CBRA流程的第三资源；
所述目标小区是否配置有第四资源，所述第四资源为能够同时用于支持波束失败恢复的CBRA流程的资源；

可以理解地，当目标小区没有配置用于非竞争随机接入(Contention-Free Random Access，CFRA)流程的第一资源；或者目标小区没有配置用于支持波束失败恢复的CFRA流程的第二资源(也就是说，配置了用于CFRA流程的资源，但CFRA没有被配置为支持波束失败恢复)；或者是用于支持波束失败恢复的CFRA流程的第二资源上的参考信号的测量值不满足测量性能要求(也就是说，配置了用于CFRA流程的资源，且CFRA被配置为支持波束失 败恢复，但资源传输性能不足以支持流程成功)；或者目标小区没有配置用于竞争随机接入(Contention Based Random Access，CBRA)流程的第三资源；或者目标小区没有配置用于支持波束失败恢复的CBRA流程的第四资源(也就是说，配置了用于CBRA流程的资源，但CBRA没有被配置为支持波束失败恢复)；或者是用于支持波束失败恢复的CBRA流程的第四资源上的参考信号的测量值不满足测量性能要求(也就是说，配置了用于CBRA流程的资源，且CFRA被配置为支持波束失败恢复，但资源传输性能不足以支持流程成功)；当满足上述条件中的至少一者时，则确定所述目标小区不具有执行波束失败恢复流程的可用资源，也就是波束失败恢复条件不成立。
其中，用于支持波束失败恢复的CFRA流程的第二资源上的参考信号可以是包括：同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)、解调参考信号(Demodulation Reference Signal，DMRS)、小区专用参考信号(Cell Reference Signal，CRS)等；上述参考信号的测量值可以是：参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)、信号与干扰噪声比(Signal to Interference plus Noise Ratio，SINR)以及BLER等。
对于不同的测量值，不满足测量性能要求的定义不同，如对于BLER，当测量值大于预设门限时认为不满足测量性能要求，而对于RSRP等，则当测量值小于预设门限时认为不满足测量性能要求。
而用于支持波束失败恢复的CBRA流程的第四资源上的参考信号也可以是包括：SSB、CSI-RS、DMRS、CRS等，上述参考信号的测量值可以是包括：RSRQ、RSRP、SINR等。
另外，该波束失败恢复条件也可以是：目标小区上是否发生的对应于检测到的波束失败事件进行波束失败恢复的失败事件，当目标小区上检测到波束失败事件，且对该波束失败事件进行波束失败恢复失败导致的波束失败恢复失败事件，这种情况下，已经表明波束失败恢复无法成功，因此可以确定波束失败恢复条件不成立，执行加快波束失败处理的第一操作。

其中，所述直接发起波束失败恢复流程可以是，直接在Scell、Pcell、Pscell或Spcell上执行CBRA流程，而不是上报到MAC层，由MAC层结合定时器和计数器进行决策波束失败事件，因此能够加快终端从波束失败中恢复。
另外，也可以是通过直接触发无线链路失败(Radio Link Failure，RLF)，或者是通过指示上层波束失败样本，来加快终端从波束失败中恢复。
或者，还可以是通过向网络侧上报指示信息，由网络侧根据具体的上报信息来决策采取何种行为，加快终端从波束失败中恢复。
需要说明的是，所述指示信息可以是通过媒体访问控制控制单元(Media Access Control Control Element，MAC CE)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)或无线资源控制(Radio Resource Control，RRC)消息携带进行上报；而所述指示信息可以是通过Scell、Pcell、Pscell或Spcell向网络侧设备进行上报，其中，向网络侧设备上报指示信息的Scell、Pcell、Pscell或Spcell可以是与前面检测到发生波束失败的所述目标小区为同一个小区，或者也可以是与发生波束失败的所述目标小区为不同的小区。
