链路质量监测方法及终端
相关申请的交叉引用
本申请主张在2018年6月15日在中国提交的中国专利申请号No.201810623953.1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，尤其涉及一种链路质量监测方法及终端。
背景技术
由于干扰、衰落等因素，网络侧与终端(User Equipment，简称UE)之间的链路可能长时间不能工作，此时会发起无线链路失败过程。UE通过向高层上报同步状态(In-sync，简称IS)或非同步状态(Out-of-sync，简称OOS)的指示，如果连续上报一定次数的OOS，则认为无线链路失败。
网络侧会给UE配置X个无线链路监测参考信号(Radio Link Monitoring Reference Signal，简称RLM-RS)用来进行无线链路监测，评估无线链路质量，无线链路质量通过假设物理下行控制信道块差错率(PDCCH-BLER)进行判断。
在新无线授权辅助接入(New Radio Licensed Assisted Access，简称NR-LAA)中，在发送信息之前，发送节点(例如网络侧设备或UE)需要做空闲信道访问/扩展的空闲信道访问(Clear Channel Assess/extended Clear Channel Assess，简称CCA/eCCA)侦听信道，当信道被判断为空时，方可开始传输。
由于非授权频段是多种技术共享，因此这种基于竞争的接入方式导致信道可用时间的不确定性。NR中固定位置的RS配置不再适用于非授权频段，因为网络侧设备即使给UE配置了周期性发送的RLM-RS，由于网络侧设备在RS发送时刻之前做的信道侦听判断信道不为空，导致网络侧设备配置某个时间点应该发送的RLM-RS实际上并没有发送。UE如果仍然按NR中已有机制，基于RS进行了假设PDCCH-BLER的评估，那么向高层上报的IS或 OOS结果的可信度会受到较大的影响。
发明内容
本公开的一些实施例提供一种链路质量监测方法及终端，用于解决在进行无线链路监测时，上报的IS或OOS结果的可信度低的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开的一些实施例提供了一种链路质量监测方法，应用于终端，包括：
检测预先配置的无线链路监控参考信号RLM-RS，确定是否接收到所述RLM-RS；
根据是否接收到所述RLM-RS，上报用于指示链路质量的同步状态In-sync或非同步状态Out-Of-Sync。
第二方面，本公开的一些实施例提供了一种终端，包括：
检测模块，用于检测预先配置的无线链路监控参考信号RLM-RS，确定是否接收到所述RLM-RS；
上报模块，用于根据是否接收到所述RLM-RS，上报用于指示链路质量的同步状态In-sync或非同步状态Out-Of-Sync。
第三方面，本公开的一些实施例提供了一种终端，包括处理器、存储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上述链路质量监测方法的步骤。
第四方面，本公开的一些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计算机程序，所述计算机程序被处理器执行时实现上述链路质量监测方法的步骤。
在本公开的一些实施例中，根据RLM-RS接收情况，进行链路质量评估，而不是无论是否接收到RLM-RS，均基于RLM-RS进行假设PDCCH-BLER的评估，从而可以提高上报的In-sync或Out-Of-Sync的可信度，从而可以提高通信效能。

具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些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。

在本公开的一些实施例中，“示例性的”或“例如”等词用于表示作例子、例证或说明。本公开的一些实施例中被描述为“示例性的”或“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更可选或更具优势。确切而言，使用“示例性的”或“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开的一些实施例提供的链路质量监测方法及终端可以应用于无线通信系统中。该无线通信系统可以采用5G系统，或演进型长期演进(Evolved Long Term Evolution，简称eLTE)系统， 或后续演进通信系统。

本公开的一些实施例提供的UE 12可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，简称UMPC)、上网本或个人数字助理(Personal Digital Assistant，简称PDA)等。所属领域技术人员可以理解，用词并不构成限制。
请参考图2，图2为本公开的一些实施例的链路质量监测方法的流程示意图，该方法应用于终端，包括：
步骤21：检测预先配置的RLM-RS，确定是否接收到所述RLM-RS；
步骤22：根据是否接收到所述RLM-RS，上报用于指示链路质量的In-sync或Out-Of-Sync。
本公开的一些实施例中，根据RLM-RS接收情况，进行链路质量评估，而不是无论是否接收到RLM-RS，均基于RLM-RS进行假设PDCCH-BLER的评估，从而可以提高上报的In-sync或Out-Of-Sync的可信度，从而可以提高通信效能。
本公开的一些实施例中的所述上报，是指向所述终端的高层上报。
本公开的一些实施例中，终端未能接收到RLM-RS，可能有两个原因造 成，一个原因是链路质量差，网络侧设备发送了RLM-RS但是终端未能接收到，一个原因是，在非授权频段上，网络侧在RLM-RS的发送时刻之前做的信道侦听判断信道不为空，导致网络侧设备配置某个时间点应该发送的RLM-RS实际上并没有发送。
本公开的一些实施例中，可选地，预先配置的RLM-RS为周期性的RLM-RS。当预先配置的RLM-RS为周期性的RLM-RS时，终端周期性地检测预先配置的RLM-RS。
本公开的一些实施例中，可选地，所述预先配置的RLM-RS的个数可以为一个，也可以多于一个，RLM-RS的个数由网络侧配置或由协议约定。可选地，在频段低于3GHz时，RLM-RS的个数的最大值为2；在频段位于3GHz-6GHz之间时，RLM-RS的个数的最大值为4；在频段大于6GHz时，RLM-RS的个数的最大值为8。
本公开的一些实施例中，可选地，所述RLM-RS可以包括：信道状态信息参考信号(Channel State Information RS，简称CSI-RS)和/或同步信号块(Synchronization Signal&PBCH Block，简称SS/PBCH Block或SSB)。
本公开的一些实施例中，可选地，所述检测预先配置的RLM-RS，确定是否接收到所述RLM-RS的步骤之前，还可以包括：
步骤22a：接收所述RLM-RS的配置信息，所述配置信息中包括：每一所述RLM-RS时频资源发送位置以及生成所述RLM-RS的序列的参数等；
所述检测预先配置的RLM-RS，确定是否接收到所述RLM-RS的步骤包括：在所述时频资源发送位置上，根据所述生成所述RLM-RS的序列的参数，对所述RLM-RS进行序列相关检测，确定是否接收到所述RLM-RS。
终端可以根据网络侧的配置，或，也可以根据协议约定，获知生成所述RLM-RS的序列的参数，当在预先配置的时频资源位置上，根据生成所述RLM-RS的序列的参数，对检测到的序列进行相关性检测，当检测到的序列的相关性高于预设数值时，判定接收到RLM-RS，否则，判定未接收到RLM-RS。所述接收到RLM-RS，所属领域技术人员一般也可称作成功接收到RLM-TS。
本公开的一些实施例中，可选地，所述根据是否接收到所述RLM-RS，上报用于指示链路质量的In-sync或Out-Of-Sync的步骤包括：
步骤221：当接收到一所述RLM-RS时，评估接收到的所述RLM-RS对应的假设PDCCH-BLER；
本公开的一些实施例中，终端可以根据Qin和Qout作为链路质量评估的指标，Qout表示下行的链路质量不能满足可靠接收要求的门限，对应于Out-Of-Sync的PDCCH BLER；Qin对应于链路质量远高于Qout的链路质量的门限，对应于In-Sync的PDCCH BLER。Qin和Qout可以是一个信干噪比(Signal to Interference plus Noise Ratio，简称SINR)门限，终端可以根据信干噪比指标获得假设PDCCH-BLER的评估。即只要判断SINR指标的估计值高于/低于对应的门限值，即可判断当前无线链路的假设PDCCH-BLER与BLER_in(上报In-sync的门限)/BLER_out(上报Out-Of-Sync的门限)的关系。当然，也不排除采用其他指标，获得假设PDCCH-BLER的评估。
步骤222：当未接收到一所述RLM-RS时，不对未接收到的所述RLM-RS对应的假设PDCCH-BLER进行评估；
步骤223：根据接收到的所述RLM-RS对应的假设PDCCH-BLER的评估结果，和/或，未接收到的所述RLM-RS的个数，上报用于指示链路质量的In-sync或Out-Of-Sync。
本公开的一些实施例中，当接收到一RLM-RS时，进行假设PDCCH-BLER的评估，当未接收到一RLM-RS时，不进行假设PDCCH-BLER的评估，但是可以记录未接收到的RLM-RS的个数，以根据具体情况，对链路质量进行评估，从而提高链路质量评估的准确度。
本公开的一些实施例中，可选地，所述根据接收到的所述RLM-RS对应的假设PDCCH-BLER的评估结果，和/或，未接收到的所述RLM-RS的个数，上报用于指示链路质量的In-sync的步骤可以包括：
当接收到的RLM-RS中的第一RLM-RS的个数大于或等于第一数值时，上报In-sync，其中，所述第一RLM-RS对应的假设PDCCH-BLER低于第一门限值。
本公开的一些实施例中，可选地，所述第一数值为1，也就是说，只要接收到的RLM-RS中的有1个RLM-RS对应的假设PDCCH-BLER低于第一门限值，则可以上报In-sync。
当需要链路提供更好的传输质量，可以提高In-sync的上报条件，进一步的：
当所述第一RLM-RS的个数大于或等于第一数值，且还满足以下条件至少之一时，上报In-sync：
1)接收到的RLM-RS中第二RLM-RS的个数小于或等于第二数值，其中，所述第二RLM-RS对应的假设PDCCH-BLER高于第二门限值；
2)第三RLM-RS的个数小于或等于第三数值，其中，所述第三RLM-RS为未接收到的RLM-RS；以及，
3)所述第二RLM-RS和所述第三RLM-RS的个数之和小于或等于第四数值。
本公开的一些实施例中，可选地，所述根据接收到的所述RLM-RS对应的假设PDCCH-BLER的评估结果，和/或，未接收到的所述RLM-RS的个数，上报用于指示链路质量的Out-Of-Sync的步骤可以包括：
当满足以下条件至少之一时，上报Out-Of-Sync：
1)接收到的RLM-RS中的第一RLM-RS的个数小于所述第一数值，其中，所述第一RLM-RS对应的假设PDCCH-BLER低于第一门限值；
2)第三RLM-RS的个数大于或等于第五数值，其中，所述第三RLM-RS为未接收到的RLM-RS；
3)接收到的RLM-RS中的第二RLM-RS和所述第三RLM-RS的个数之和大于或等于第六数值，其中，所述第二RLM-RS对应的假设PDCCH-BLER高于第二门限值。
4)所述第二RLM-RS的个数大于或等于第七数值。
本公开的一些实施例中，上述第一数值、所述第二数值、所述第三数值、所述第四数值、所述第五数值、所述第六数值和所述第七数值中的至少之一由所述终端确定，或，由网络侧设备通过无线资源控制(Radio Resource Control，简称RRC)信令配置，或，由所述网络侧设备通过媒体访问控制层控制单元(Media Access Control Element，简称MAC CE)指示，或，由所述网络侧设备通过下行控制信息(Downlink Control Information，简称DCI)指示。
所述第一门限和第二门限也可以由所述终端确定，或，由网络侧设备通 过RRC信令配置，或，由所述网络侧设备通过MAC CE指示，或，由所述网络侧设备通过DCI指示。
本公开的一些实施例的上述方法，可以应用于授权频段的无线链路监测，也可以应用于非授权频段的无线链路监测。
下面结合具体实施例，对本公开的链路质量监测方法进行举例说明。
在一具体实施例中，终端根据网络侧设备发送的RRC信令中的配置，采用CSI-RS的作为RLM-RS，假设网络侧设备配置终端采用8个CSI-RS进行无线链路监测。
终端根据网络侧设备发送的RRC信令中的配置，在配置的CSI-RS预期发送的时频资源上检测该CSI-RS，确定是否接收到该CSI-RS；
a)如果接收到该CSI-RS，评估CSI-RS对应的假设PDCCH BLER；
b)如果未接收到该CSI-RS，不对该CSI-RS对应的假设PDCCH BLER进行评估。
如果对于网络侧设备配置的8个CSI-RS，其中，有A个CSI-RS对应的假设PDCCH BLER低于门限值BLER_in(BLER_in即上述实施例中的第一门限值)；B个CSI-RS对应的假设PDCCH BLER高于门限值BLER_Q_out(BLER_Q_out即上述实施例中的第二门限值)；C个CSI-RS，终端未接收到，不进行该CSI-RS对应的假设PDCCH BLER的评估。
终端根据上述3种状态的CSI-RS的数量，确定给高层上报In-Sync还是Out-Of-Sync，具体的：
a)A>＝TH_A(TH_A即上述实施例中的第一数值)上报in-Sync；
如果需要链路提供更好的传输质量，即需要更严格的上报In-Sync的条件时，可以将TH_A设置为较大的值；或
满足A>＝TH_A的同时，还需要满足C<＝TH_C_in(TH_C_in即上述实施例中的第三数值)，B<＝TH_B_in(TH_B_in即上述实施例中的第二数值)，B+C<＝TH_BC_in(TH_BC_in即上述实施例中的第四数值)三个条件中至少一个条件时，上报In-Sync。

A<TH_A；
C>＝TH_C_out(TH_C_out即上述实施例中的第五数值)；
B>＝TH_B_out(TH_B_out即上述实施例中的第七数值)；
B+C>＝TH_BC_Out(TH_BC_Out即上述实施例中的第六数值)。
当需要链路提供更好的传输质量时，可以将TH_B_out，TH_C_out，TH_BC_out设置成较小的数值；反之可以设置成较大的值。
TH_A，TH_B_in，TH_C_in，TH_C_out，TH_BC_in，TH_BC_out的数值可以由所述终端确定，或，由网络侧设备通过RRC信令配置，或，由所述网络侧设备通过MAC CE指示，或，由所述网络侧设备通过DCI指示。
