技术领域
本发明涉及无线通信技术领域，尤其是涉及一种参考信号的确定方法及相关设备。
背景技术
在无线通信系统(如第五代移动通信系统5G NR等)中，为保证通信系统中设备之间的正常通信，通常在通信过程中会进行通信质量的检测，以使通信故障时及时对故障进行修复或者切换等，例如，处于连接态的终端(User Equipment，UE)通过无线链路监测(Radio Link Monitoring，RLM)对当前服务小区的下行链路质量进行评估，当评估下行链路质量无法满足其需求时，终端进行新小区的搜索和选择以重建无线链路。
其中，终端可以通过使用网络侧配置的控制资源集(Control resource set，CORESET)的激活的传输配置指示(Transmission Configuration Indicator，TCI)状态(state)对应的参考信号(Reference Signal，RS)进行RLM，具体地，根据每个CORESET的搜索空间集(Search Space set，SS set)配置的物理下行控制信道(Physical downlink control channel，PDCCH)监听周期，在网络侧配置的所有CORESET中选择PDCCH监听周期最短搜索空间集关联的CORESET，并将选择的CORESET的激活TCI state指示的RS作为RLM-RS。但是，由于终端进行PDCCH监听的搜索空间和高层信令配置的PDCCH搜索空间，目前终端基于上述方式选择的CORESET可能并不适合进行RLM，这样会导致RLM的准确性降低。
发明内容

其中，所述第一搜索空间集为当前进行物理下行控制信道PDCCH监听的搜索空间集；所述第一参考信号包括无线链路监测参考信号RLM-RS或者波束失败监测参考信号BFD-RS。
第三方面，本发明实施例还提供一种终端，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第一方面所述的参考信号的确定方法中的步骤。

具体实施方式
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。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“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优选或更具优势。确切而言，使用“示例性的”或者“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发明的实施例。本发明提供的实施例可以应用于无线通信系统中。该无线通信系统可以为5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
图1是本发明实施例提供的一种网络系统的结构图，如图1所示，包括终端11、网络侧设备12，其中，终端11可以是移动通信设备，例如：可以 是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等，需要说明的是，在本发明实施例中并不限定终端11的具体类型。上述网络侧设备12可以是5G网络侧设备(例如：gNB、5G NR NB)，或者可以是4G网络侧设备(例如：eNB)，或者可以是3G网络侧设备(例如：NB)，或者后续演进通信系统中的网络侧设备，等等，需要说明的是，在本发明实施例中并不限定网络侧设备12的具体类型。
请参见图2，图2是本实施例提供的一种参考信号的确定方法的流程示意图，应用于终端，如图2所示，上述参考信号的确定方法包括如下步骤：
步骤201、基于第一搜索空间集(Search Space set，SS set)，确定第一参考信号；
其中，所述第一搜索空间集为当前进行物理下行控制信道(Physical downlink control channel，PDCCH)监听的搜索空间集；所述第一参考信号包括无线链路监测参考信号(Radio Link Monitoring Reference Signal，RLM-RS)或者波束失败监测参考信号(Beam Failure Detection Reference Signal,BFD-RS)。
这里，终端可以基于当前进行PDCCH监听的搜索空间集，确定RLM-RS或者BFD-RS，即仅在当前进行PDCCH的搜索空间集关联的控制资源集(Control resource set，CORESET)选择用于进行RLM或者BFD的CORESET，相比于在网络侧配置的所有CORESET中选择用于进行RLM或者BFD的CORESET，可以避免使用不进行PDCCH监听的CORESET的激活传输配置指示(Transmission Configuration Indicator，TCI)状态(state)对应的RS进行RLM或者BFD，从而使选择的CORESET更合适，进而可以提升RLM的准确性。
需要说明的是，在网络侧为终端配置有CORESET的情况下，终端可以使用网络侧配置的CORESET进行RLM或者BFD。具体地，在现有的终端进行RLM或者BFD过程中，终端可以根据每个CORESET的搜索空间集配置的PDCCH监听周期，在网络侧配置的所有CORESET中选择PDCCH监听 周期最短搜索空间集关联的CORESET，并将选择的CORESET的激活TCI state指示的RS作为RLM-RS或者BFD-RS。
本实施例中，是在终端进行RLM或者BFD过程中，终端根据网络侧配置的所有CORESET的搜索空间集的PDCCH的监听状态，在网络侧配置的所有CORESET的搜索空间集中，确定当前进行PDCCH监听的至少一个搜索空间集即第一搜索空间集，并基于第一搜索空间集确定RLM-RS或者BFD-RS。
其中，上述基于第一搜索空间集，确定第一参考信号，可以是终端在第一搜索空间集中确定部分或者全部搜索空间集，并将确定的搜索空间集关联的CORESET的激活TCI state指示的RS作为上述RLM-RS或者BFD-RS。
具体地，上述在第一搜索空间集中确定部分或者全部搜索空间集，可以是终端根据第一搜索空间集中每一搜索空间集配置的PDCCH监听周期的排序，在排序中选择PDCCH监听周期最短的预设数量的搜索空间集，该预设数量为终端最多可监听的RLM-RS或者BFD-RS的数量。
例如，在终端进行RLM的过程中，在网络侧配置有5个CORESET且终端最多可监听2个RLM-RS的情况下，且在该5个CORESET的搜索空间集配置的PDCCH监听周期的排序中，该排序以降序方式排列，且CORESET1的搜索空间集的PDCCH监听周期和CORESET2的搜索空间集的PDCCH监听周期排在最后，即CORESET1的搜索空间集的PDCCH监听周期和CORESET2的搜索空间集的PDCCH监听周期最短，则终端将CORESET1和CORESET2的激活TCI state指示的RS作为上述RLM-RS。
需要说明的是，上述CORESET的激活TCI state指示的RS，可以是网络侧为每一CORESET配置有至少一个TCI state，且每个TCI state配置有信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或者同步信号块(Synchronization Signal and PBCH Block，SSB)，且会激活至少一个TCI state的一个TCI state，终端在RLM或者BFD过程中，终端将该激活TCI state指示的CSI-RS或者SSB作为上述RLM-RS或者BFD-RS，即RLM-RS或者BFD-RS为激活TCI state指示的CSI-RS或者SSB。
本实施例中，上述第一搜索空间集可以是任意的当前进行PDCCH监听 的至少一个搜索空间集。
或者，在一些实施方式中，所述第一搜索空间集包括如下至少一项：
网络侧配置的搜索空间集中的至少一个搜索空间集，且所述至少一个搜索空间集属于至少一个搜索空间集组；
终端根据PDCCH指示或者计时器运行状态，确定进行PDCCH监听的至少一个搜索空间集组中的搜索空间集；
由网络侧配置为默认的搜索空间集组中的搜索空间集；
未配置有搜索空间集组标识的搜索空间集；
多个搜索空间集组的搜索空间集中PDCCH监听周期最短或者最长的搜索空间集合；
多个搜索空间集组中索引值最大或最小的搜索空间集。
这里，上述第一搜索空间集可以包括上述至少一项，从而可以选择到更合适的CORESET用于RLM或者BFD，进一步提升RLM或者BFD的准确性。
需要说明的是，在无线通信系统中，网络侧可以将配置的所有CORESET中的搜索空间集分为多组搜索空间集组，且每组搜索空间集组配置有对应的搜索空间集组标识；当然，网络侧也可以配置部分搜索空间集不属于任何搜索空间集组，即不给该搜索空间集配置搜索空间集组标识，以使在RLM或者BFD中，终端可以根据搜索空间集组、搜索空间集组标识或者是否配置搜索空间集组标识进行相应的处理。
本实施例中，在终端使用确定的第一参考信号进行RLM或者BFD过程中，终端在一些情况下可能动态地进行搜索空间集的切换(即Search Space set Switching)，即切换当前监听的PDCCH的搜索空间集，使得上述第一搜索空间集中的搜索空间集发生改变。
例如，在网络侧将配置的所有CORESET中的搜索空间集分为多组搜索空间集组的情况下，网络侧可以通过PDCCH指示终端进行PDCCH监听的搜索空间集组，在PDCCH指示的搜索空间集组与当前使用的搜索空间集组不同时，使得当前进行PDCCH监听的搜索空间集组的搜索空间集，切换成另一组搜索空间集组的搜索空间集；或者，若在计时器运行期间使用一组搜 索空间集组的搜索空间集进行PDCCH监听，当计时器到期时，终端自动触发使用另一组搜索空间集组的搜索空间集进行PDCCH监听。
可以理解的是，在本发明实施例对计时器(或者称为定时器)的参数不做具体限定。该计时器可以是为Search Space Set组切换定义或者配置的计时器，或者其他的计时器，例如，非连续接收持续时间定时器(drxOnDurationTimer)，DRX静止定时器(drxInactivityTimer)，随机接入竞争解决定时器(ra-ContentionResolutionTimer)，波束失败恢复定时器(beamFailureRecoveryTimer)，配置授权定时器(configuredGrantTimer)，上行调度禁止定时器(sr-ProhibitTimer)，部分带宽去激活定时器(bwp-InactivityTimer)，数据去激活定时器(dataInactivityTimer)，辅小区去激活定时器(sCellDeactivationTimer)，下行DRX重传定时器(drx-RetransmissionTimerDL)，上行DRX重传定时器drx-RetransmissionTimerUL，T310计时器等。
另外，在当前监听的PDCCH的搜索空间集发生切换，即上述第一搜索空间集中的搜索空间集发生改变的情况下，第一搜索空间集中确定的配置有PDCCH监听周期最短的搜索空间集也有可能发生改变。
在一些实施方式中，上述参考信号的确定方法还可以包括：
根据所述第一搜索空间集，确定在所述第一搜索空间集关联的第一CORESET上是否有PDCCH监听；
根据所述第一搜索空间集，确定PDCCH监听周期最短的搜索空间集关联的第二CORESET。
这里，终端可以及时监控进行PDCCH监听的CORESET是否发生切换；以及，及时确定配置有PDCCH监听周期最短的搜索空间集是否发生改变。
需要说明的是，上述第一CORESET可以是上述第一搜索空间集中至少一个搜索空间集关联的CORESET。
在进一步的实施方式中，在根据所述第一搜索空间集，确定在所述第一搜索空间集关联的第一CORESET上是否有PDCCH监听之后，还包括：
在第一控制资源集上没有PDCCH监听的情况下，确定第三CORESET的激活TCI state指示的CSI-RS或者SSB为所述第一参考信号；
其中，所述第三CORESET为所述第一控制资源集之外的控制资源集。
这里，在第一搜索空间集关联的第一CORESET上没有PDCCH监听，即当前进行PDCCH监听的搜索空间集发生切换的情况下，终端可以将第一CORESET之外的CORESET的激活TCI state指示的CSI-RS或者SSB确定为第一参考信号，从而在进行PDCCH监听的搜索空间集发生切换时及时切换用于RLM或者BFD的CORESET，避免使用不进行PDCCH监听的CORESET进行RLM或者BFD，进一步提升RLM的准确性。
例如，在终端进行RLM的过程中，假设网络侧配置有5个CORESET且终端最多可监听2个RLM-RS，而且在当前时刻，CORESET1和CORESET2(即第一CORESET)用于进行RLM，上述第一搜索空间集包括CORESET1的搜索空间集1和CORESET2的搜索空间集2，搜索空间集1和搜索空间集2均属于搜索空间集组1，若网络侧通过PDCCH指示终端切换至使用搜索空间集组2的搜索空间集进行PDCCH监听，且搜索空间集组2包括CORESET3(即第三CORESET)的搜索空间集3，则终端将CORESET3的激活TCI state指示的CSI-RS或者SSB确定为RLM-RS。
本实施例中，在网络侧配置的所有CORESET中，可能存在多个CORESET的搜索空间集配置的PDCCH监听周期最短，如该多个CORESET的搜索空间集配置的PDCCH监听周期相同且为最短，而该多个CORESET的数量超出上述预设数量，在此情况下，终端可以根据该多个CORESET的索引值，优先选择索引值满足预设条件的预设数量的CORESET进行RLM或者BFD。
例如，在终端进行BFD的过程中，在网络侧配置有5个CORESET且终端最多可监听1个RLM-RS的情况下，若CORESET3的搜索空间集的PDCCH监听周期和CORESET4的搜索空间集的PDCCH监听周期相同且最短，且CORESET3的索引值满足预设条件，则终端将CORESET3的激活TCI state指示的RS作为上述BFD-RS。
具体地，在上述方法还包括根据第一搜索空间集，确定PDCCH监听周期最短的搜索空间集关联的第二CORESET的情况下，在多个CORESET的最短的PDCCH监听周期相同的情况下，所述第二CORESET为索引值最大 或者最小的N个CORESET，N为正整数，其中，所述多个CORESET与所述第一搜索空间集关联。这样，在存在第一搜索空间集关联的多个CORESET的最短的PDCCH监听周期相同，即具有多个CORESET配置有最短的PDCCH监听周期的情况下，终端可以根据该多个CORESET的索引值确定用于RLM或者BFD的CORESET(即第二CORESET)，进一步使选择的CORESET更合适，进而提升RLM或者BFD的准确性。
需要说明的是，上述N为终端最多可监听的RLM-RS或者BFD-RS的数量，即上述N为上述预设数量，且上述N由终端工作的频段的最大SSB决定。例如，在一些实施方式中，所述终端工作第一频段，所述第一频段的最大SSB为4，那么，此时终端最多可监听的RLM-RS或者BFD-RS为2个，即N＝2。
另外，上述终端确定第一参考信号，是将选择用于RLM或者BFD的CORESET的激活TCI state指示的CSI-RS或者SSB确定为上述第一参考信号，故在上述方法还包括根据第一搜索空间集，确定PDCCH监听周期最短的搜索空间集关联的第二CORESET的情况下，上述所述第一参考信号为第二控制资源集的激活TCI state指示的CSI-RS或者SSB，从而实现及时对参考信号的更新。
本实施例中，在终端使用上述第一参考信号进行RLM的过程中，终端可以根据第一参考信号、N310计数器以及N311计数器控制RLM的T310定时器的运行，并根据T310定时器的运行状态确定RLM是否失败，具体如下：
如果终端的物理层测量计算到当前激活的带宽部分(Bandwidth Part，BWP)上X个RLM-RS(该X个RLM-RS为第一参考信号中的RLM-RS)评估的链路质量都差于高层配置的门限Q out，则终端向高层上报out-of-sync(OOS)指示；如果高层连续接收到N310个OOS指示，则启动T310定时器；
如果终端的物理层测量到当前激活的BWP上X个RLM-RS评估的链路质量至少有一个好于高层配置的门限Qin，则向高层上报in-sync(IS)指示。如果高层接连续收到N311个IS指示，则停止T310定时器的运行；
当T310定时器运行超时，终端判定无线链路失败(Radio link failure， RLF)，终端与网络间的用户面数据传输中断；
其中，X值与终端工作频段关联，例如，在低于3GHz的情况下，X的最大值为2；在3GHz-6GHz之间，X＝4；在大于6GHz的情况下，X＝8；N310的数值、N311的数值以及T310的运行时间长度都是由网络配置。
在一些实施方式中，所述基于第一搜索空间集，确定第一参考信号之后，还包括：
在所述第一参考信号发生更改的情况下，若所述第一参考信号包括RLM-RS，则执行如下至少一项：
将N310计数器置为0；
将N311计数器置为0；
在T310计时器运行的情况下，重置所述T310计时器。
这里，终端可以在第一参考信号发生更改即进行搜索空间集的切换的情况下，对RLM的N310计数器和N311计数器置0，以及重置T310计时器，从而进一步提升RLM的准确性。
另外，在终端使用上述第一参考信号进行BFD的过程中，网络侧为每个配置给终端的BWP配置Y个周期性发送的BFD-RS(该Y个周期性发送的BFD-RS为第一参考信号中的参考信号)，BFD-RS可以是周期的CSI-RS或SSB；终端的物理层将对BFD-RS进行测量，并根据测量结果判断是否向高层上报波束失败事件(Beam Failure Instance，BFI)指示，具体如下：
如果终端的物理层测量计算出某个服务小区终端激活的BWP上全部serving BFD-RS(s)对应的链路质量差于门限值，则向高层(如媒体接入控制(Medium Access Control，MAC)层)上报一个BFI指示；反之，则不向高层发送任何指示；
终端的高层设置了一个BFD定时器(BFD timer)和一个BFD计数器(BFI counter)，当终端高层收到物理层上报的BFI指示后开启或重启BFD计时器，并且对BFD计数器进行累加1操作；如果BFD计数器计数大于等于网络侧配置的最大次数时，则终端判定当前服务小区发生了波束失败，触发波束恢复过程。另外，如果波束失败检测定时器运行超时后，终端的高层会重置BFD计数器的计数为0。
在一些实施方式中，所述基于第一搜索空间集，确定第一参考信号之后，还包括：
在所述第一参考信号发生更改的情况下，若所述第一参考信号包括BFD-RS，则执行如下至少一项：
BFD计数器置为0；
BFD定时器重置。
这里，终端可以在第一参考信号发生更改即进行搜索空间集的切换的情况下，对BFD计数器置0，以及重置BFD定时器，从而进一步提升BFD的准确性。
另外，在一些实施方式中，所述基于第一搜索空间集，确定第一参考信号，包括：
在确定所述终端未配置有参考信号的情况下，基于第一搜索空间集，确定第一参考信号。
