一种无线电链路监测方法及装置
本申请要求在2017年6月16日提交中国专利局、申请号为201710459267.0、发明名称为“一种无线电链路监测方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种无线电链路监测方法及装置。
背景技术
无线电链路监测(radio link monitoring，RLM)功能是由用户设备(user equipment，UE)监视主服务小区的下行链路信号质量，以便判断UE是否处于同步或不同步状态。
现有的LTE RLM设计和实现具体为：定义假设的物理下行控制信道(hypothetical physical downlink control channel，假设的PDCCH)并给出对应于同步和不同步阈值的假设的PDCCH的丢包率(block error rate，BLER)；在UE设计中，实现从假设的PDCCH的BLER到同步不同步阈值的映射；在UE RLM操作中，从小区专属参考信号(cell specific reference signal，CRS)测量下行无线链路质量，并将测量结果与同步和不同步阈值进行比较，以确定UE处于同步或不同状态。
在长期演进(Long Term Evolution，LTE)系统中，UE可以通过估计CRS的质量来实现RLM。判断UE同步阈值

和非同步的阈值
Figure PCTCN2018083400-appb-000002
对应于假设的PDCCH的10％和2％的BLER。
目前5G新空口(new radio，NR)系统要比LTE复杂得多。5G NR需要支持从低频到高频带工作，并且通过波束形成支持更广泛的无线电链路业务，具有不同的链路延迟、数据速率和可靠性等要求。因此，NR不能采用基于固定假设的PDCCH的方法，来实现RLM。另外，NR的系统同步块(system synchronization block，SS块)不包含PDCCH，如果采用LTE中所提供的方法实现RLM，则还需要单独定义假设的PDCCH以实现从实际的PDCCH BLER至同步或非同步的阈值

和

的映射；这种方案会使得RLM测试不能与NR PDCCH性能测试同时进行，定义RLM性能要求时复杂，并且不能通过调整阈值来提供应有的灵活性以支持不同的具体系统。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
应理解，本发明的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、新空口(New Radio，NR)等。
还应理解，在本发明实施例中，用户设备(User Equipment，UE)包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话 (或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中，基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是TD-SCDMA或WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNodeB或eNB或e-NodeB，evolutional Node B)，或者是5G NR中的基站(gNB)，本发明并不限定。
本申请实施例提供的方案利用SS块中所提供的信息得到判断UE是否同步的判断阈值；相对于现有技术中所提供的利用假设的PDCCH得到判断阈值的方式本申请所提供的方法不用单独定义假设的PDCCH，实现方式简单便于实现。本申请所提供的一种无线电链路监测方法，应用到用户设备UE进行无线电链路监测时，该方法的主要实现步骤包括：
用户设备UE监测主服务小区的下行链路信号得到监测结果；
所述UE将所述监测结果与获得的同步阈值进行比较确定所述UE是否处于同步状态；其中，所述同步阈值根据预设参数值确定。
在具体实现的时候，本申请实施例所提供的方法可以基于目前5G NR(new radio，新空口)系统中存在的多种信道和/信号确定同步阈值，本申请实施例中以以下两种方式为具体实例进行说明：
a，UE根据所述UE接收到的系统同步SS块的误码率BLER映射确定所述同步阈值；或者
b，所述UE根据网络侧设备预配置的参数值确定所述同步阈值。
以下结合说明书附图对本申请实施例所提供的一种无线电链路监测方法做进一步详细的说明；
实施例一
当UE根据所述UE接收到的系统同步SS块的误码率BLER映射确定所述同步阈值，本申请提供一种无线电链路监测方法，该方法具体实现方式可以包括以下步骤(方法流程如图1所示)：
步骤101，UE进行无线电链路监测时，用户设备UE监测主服务小区的下行链路信号得到监测结果；
步骤102，该UE将所述监测结果与获得的同步阈值进行比较确定所述UE是否处于同步状态；其中，所述同步阈值根据所述UE接收到的系统同步SS块的误码率BLER映射得到。
因为NR的SS块不包含PDCCH，所以不能采用LTE中所提供的假设的PDCCH方式实现RLM，基于现有技术的该问题本申请实施例所提供的方法利用NR的SS块中存在的信道和/或信息映射UE的同步或非同步阈值，从而提供NR系统能够实现的RLM实现方式。
针对现有技术定义RLM性能要求时复杂，且不能与NR PDCCH性能测试同时进行、并且不能通过调整阈值来提供应有的灵活性以支持不同的具体系统的问题，本申请所提供的方案可使用NR物理广播信道(Physical broadcast channel，PBCH)作为实现NR RLM的信道(即将新空口NR PBCH的BLER作为SS的误码率BLER)，并且基于NR PBCH的BLER来直接定义UE RLM准则。即UE基于服务波束的PBCH BLER与预定义的或配置确定同步阈值，从而根据该同步阈值来确定UE是否处于同步状态。
与基于假设的PDCCH信道的方法对比，本申请实施例所提供的方法所采用的信道是每个NR SS块都包括的PBCH。因此，无需定义假设的PDCCH；另外，UE更容易实现从实际的PBCH BLER至同步阈值的映射，可使定义RLM性能要求时简单直接；并且测试RLM性能工作可以最小化，RLM测试可以与NR PBCH性能测试同时进行。
本申请所提供的方法利用SS块的BLER映射得到同步阈值，进一步具体可以利用以下参数信号来得到SS块的BLER，包括：
利用每个SS块中用于预设波束方向的主同步序列(Primary synchronization signal，PSS)、辅同步序列(Secondary synchronization signal，SSS)或PBCH中解调参考信号(Demodulation Reference Signal，DMRS)计算所述系统同步SS块的BLER。
NR RLM需要支持具有多个射频波束的工作环境。为了在多波束工作环境下支持NR移动性，NR引入了同步信号(Synchronization signal，SS)块和SS集合块。每个SS块包括用于预设波束方向的PSS、SSS和PBCH。每个SS集合块包括多个SS块用于实现波束扫描，每个SS块集合的传输覆盖一个波束扫描操作中的特定区域，NR UE移动性主要基于SS块的测量。
在5G NR中对于所有载波频率，用于初始小区搜索的默认的NR SS集合的周期定义为20毫秒(ms)。对空闲和连接模式的UE，NR SS集合的周期取值集合为{5ms，10ms，20ms，40ms，80ms，160ms}。
为了达到利用NR SS测量误码率的效果，需要信号的发送周期小于RLM的测量要求，所以在本申请提供的方案中，对于空闲和连接模式的UE，网络侧设备可以根据自身支持UE移动性和RLM的要求配置NR SS集合的周期性，具体实现可以是：
当所述UE为空闲模式或连接模式时，根据网络侧设备发送的配置信息确定所述PSS、SSS或DMRS的发送周期。
配置的PSS、SSS或DMRS的发送周期选择原则是：发送周期与所述UE的移动速度 对应；其中，第一移动速度所对应的发送周期小于第二移动速度对应的发送周期，第一移动速度大于第二移动速度。
例如：当UE移动速度为30～60Km/h时，配置NR SS的集合周期为20ms；当UE移动速度为3km/h时，配置NR SS的集合周期为80ms。
进一步，由于LTE RLM实现里同步阈值是依赖于UE来实现，网络侧设备实际上不能控制UE如何设置同步阈值，所以LTE RLM设计不能支持不同的具体系统；因此，LTE RLM设计既不灵活，也难以保证系统性能。鉴于现有技术的该问题，本申请实施例所提供的方案中，网络侧设备还可以根据具体环境需求对RLM的同步阈值进行调整，具体实现方式可以是：
网络侧设备根据当前对UE提供的网络服务确定需要对RLM的同步阈值进行调整，则可以通过信号指令将调整后的同步阈值发送到UE。
UE若接收到网络侧设备发送的对所述同步阈值进行调整的信号指令，则根据所述信号指令对所述同步阈值进行调整。该实施例中，对同步阈值进行调整的具体实现可以是：UE从信号指令中获取网络侧设备设置的同步阈值，利用信号指令中获得的同步阈值调整原有的同步阈值。
实施例二
为了提供NR RLM支持不同类型系统的灵活性，本发明还提出允许网络对每个UE进行同步阈值的调整配置服务(所述UE根据网络侧设备预配置的参数值确定所述同步阈值)。本申请实施例提供一种无线电链路监测方法(如图2所示)，包括：
步骤201，UE进行无线电链路监测时，监测主服务小区的下行链路信号得到监测结果；
步骤202，UE将所述监测结果和获得的同步阈值进行比较确定所述UE是否处于同步状态；其中，所述同步阈值为网络侧设备预配置的参数值。
本申请实施例中，网络侧设备直接配置NR RLM的同步阈值，不通过UE从预定义的PBCH或PDCCH信道的BLER中映射，网络侧设备可以方便及时的调整UE的同步阈值从而提供RLM应有的灵活性从而支持不同系统。
RLM虽然是以PDCCH的BLER作为判断标准，但BLER统计需要一个较长期的过程，UE不能统计PDCCH的BLER，因此UE在进行实际链路监测时，以及在测试中不能通过统计误码率判断链路质量，还是要用接收信号的信噪比来进行无线链路质量的判决，所以本申请实施例中，网络侧设备配置的同步阈值可以基于同步信号NR-PSS、NR-SSS和PBCH的DMRS的参考信号接收质量(Reference Signal Received Quality，RSRQ)或信干噪比(signal to interference and noise ratio，SINR)。
对应的UE在监测主服务小区的下行链路信号得到监测结果时的具体实现可以是：
UE监测所述服务小区的同步信号PSS、SSS和PBCH的DMRS的参考信号接收质量 RSRQ或信干噪比SINR得到监测结果。
本申请实施例所提供的方法不仅提供了让网络根据支持不同特征来控制同步阈值的灵活性，而且使得NR RLM实现更加容易。UE也不必实现从预定义的PBCH或PDCCH信道的BLER中导出是否处于同步状态的同步阈值。
实施例三
如图3所示，本申请还提供另外一种无线电链路监测方法，该包括可以包括以下步骤：
步骤301，网络侧设备通过信号指令发送预设同步阈值到UE；
步骤302，UE进行无线电链路监测时，监测主服务小区的下行链路信号得到监测结果，并将所述监测结果和与所述预设同步阈值进行比较确定所述UE是否处于同步状态。
实施例四
如图4所示，本申请实施例还提供一种用户设备，该用户设备包括：
监测单元401，用于监测主服务小区的下行链路信号得到监测结果；
判断单元402，用于将所述监测结果与获得的同步阈值进行比较确定所述UE是否处于同步状态；其中，所述同步阈值根据预设参数值确定。
可选的，该用户设备还可以包括：
确定单元，用于根据所述UE接收到的系统同步SS块的误码率BLER映射确定所述同步阈值；或者根据网络侧设备预配置的参数值确定所述同步阈值。
其中，该SS块的误码率BLER为新空口NR物理广播信道PBCH的BLER。
另外，该用户设备还可以包括误码率确定单元，用于利用每个SS块中用于预设波束方向的主同步序列PSS、辅同步序列SSS或PBCH中解调参考信号DMRS计算所述系统同步SS块的BLER。
可选的，误码率确定单元还用于当所述UE为空闲模式或连接模式时，根据网络侧设备发送的配置信息确定所述PSS、SSS或DMRS的发送周期。
可选的，该发送周期与所述UE的移动速度对应；其中，第一移动速度所对应的发送周期小于第二移动速度对应的发送周期，第一移动速度大于第二移动速度。
可选的，该用户设备还可以包括：
调整单元，用于若接收到网络侧设备发送的对所述同步阈值进行调整的信号指令，则根据所述信号指令对所述同步阈值进行调整。
RLM虽然是以PDCCH的BLER作为判断标准，但BLER统计需要一个较长期的过程，UE不能统计PDCCH的BLER，因此UE在进行实际链路监测时，以及在测试中不能通过统计误码率判断链路质量，还是要用接收信号的信噪比来进行无线链路质量的判决，所以本申请实施例中，所述用户设备中的监测单元具体具体用于监测所述服务小区的同步信号PSS、SSS和PBCH的DMRS的参考信号接收质量RSRQ或信干噪比SINR得到监测结果。
实施例五
如图5所示，本申请实施例还提供一种无线电链路监测系统，包括：
网络侧设备501，用于通过信号指令发送预设同步阈值到所述UE；
502用户设备(UE)，在进行无线电链路监测时，用于监测主服务小区的下行链路信号得到监测结果，并将所述监测结果和与所述预设同步阈值进行比较确定所述UE是否处于同步状态。
本发明实施例还提供一种计算机装置，所述装置包括处理器，所述处理器用于执行存储器中存储的计算机程序时实现如实施例一、二或三中所述方法的步骤。
本发明实施例还提供一种计算机可读存储介质，其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实施例一、二或三中所述方法的步骤。
因为NR的SS块不包含PDCCH，所以不能采用LTE中所提供的假设的PDCCH方式实现RLM，基于现有技术的该问题本申请实施例所提供的方法利用NR的SS块中存在的信道和/或信息映射UE的同步或非同步阈值，从而提供NR系统能够实现的RLM实现方式。
与基于假设的PDCCH信道的方法对比，本申请实施例所提供的方法所采用的信道是每个NR SS块都包括的PBCH。因此，无需定义假设的PDCCH；另外，UE更容易实现从实际的PBCH BLER至同步阈值的映射，可使定义RLM性能要求时简单直接；并且测试RLM性能工作可以最小化，RLM测试可以与NR PBCH性能测试同时进行。
