Abstract

本发明公开了一种确定参考信号 (RS) 的方法、用户设备 (UE) 及计算机存储介质，其中方法包括：在所述 UE 需要确定用于测量的 RS 时，判断是否采用目标控制资源集合所对应的 RS。

Description

确定参考信号的方法、用户设备及计算机存储介质 技术领域
本发明涉及信息处理技术领域，尤其涉及一种确定参考信号(RS)的方法、用户设备(UE)及计算机存储介质。
背景技术
在波束失败恢复流程中，为了进行beam failure detection，UE需要测量PDCCH对应的参考信号(例如CSI-RS，SS/PBCH block等)，目前有两种方法：方法1：网络配置一组RS来让UE作为beam failure detection的测量信号；方法2：如果网络没有配置，UE根据准正交关系(QCL)确定一组RS用来作为beam failure detection的测量信号。
但是，目前上述的方案，控制资源集合(CORESET)0如何处理，是否需要把CORESET 0对应的信号用于波束失败检测是需要进一步确定的。
发明内容
为解决上述技术问题，本发明实施例提供了一种确定参考信号(RS)的方法、网络设备、用户设备(UE)及计算机存储介质。
本发明实施例提供一种确定参考信号RS的方法，应用于用户设备UE，所述方法包括：
在所述UE需要确定用于测量的RS时，判断是否采用目标控制资源集合所对应的RS。
本发明实施例提供一种UE，包括：

本发明实施例提供的一种UE，包括：处理器和用于存储能够在处理器上运行的计算机程序的存储器，
其中，所述处理器用于运行所述计算机程序时，执行前述方法的步骤。
本发明实施例提供的一种计算机存储介质，所述计算机存储介质存储有计算机可执行指令，所述计算机可执行指令被执行时实现前述方法步骤。
本发明实施例的技术方案，就能够在所述UE需要确定用于测量的RS时，判断是否采用目标控制资源集合所对应的RS；如此，能够使得UE能够选取更符合需求的RS进行测量，从而提供系统效率。
附图说明
图1为本发明实施例提供的一种确定RS的方法流程示意图；
图2为本发明实施例用户设备UE组成结构示意图；
图3为本发明实施例的一种硬件架构示意图。
具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容。首先需要指出在本发明实施例中提出的RS可以指RS信号，或者RS资源，或者RS资源组，比如，CSI-RS资源、SS/PBCH块的指示(Index)、或者CSI-RS资源组标识等等，都在本发明实施例中RS的概念范围内，只是不再进行穷举。
下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种确定参考信号(RS)的方法，应用于用户设备(UE)，包括：
在所述UE需要确定用于测量的RS时，判断是否采用目标控制资源集 合所对应的RS。
本实施例中，关于判断是否采用目标控制资源集合对应的RS的方式，可以参见以下说明：
方式1、
本方式针对如何判断不采用目标控制资源集合对应的RS的处理：
当目标控制资源集合为通过PBCH指示、且没有其他的UE参数配置时，在所述UE需要确定用于测量的RS时，不采用目标控制资源集合所对应的RS。
本实施例中所述目标控制资源集合可以为控制资源集合CORESET 0，也就是标识为0的CORESET。
示例性的，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI等)。如果当前的CORESET 0是通过PBCH指示的，而没有其他的UE-specific configuration；则为了beam failure detection，当UE需要确定用于测量的RS时，不考虑CORESET 0对应的参考信号。
CORESET 0可以由PBCH指示的，UE在初始接入时，上传PRACH信号，网络通过接收到的PRACH信号，可以知道UE对应的SS/PBCH block是哪个，因此可以在这个对应的beam上发送在CORESET 0对应的资源上发送PDCCH。
方式2、
本方式针对如何判断采用目标控制资源集合对应的RS的处理：
当目标控制资源集合为通过UE参数配置指示时，在所述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
其中，所述目标控制资源集合为通过UE参数配置指示，包括：
通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制 资源集合。
也就是，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
本方式中，CORESET 0可以有RRC来配置(UE-specific configured)，这时候，网络明确指示QCL相关信息，CORESET 0上也可以传输UE-specific的PDCCH。
方式3、
本方式针对如何判断采用目标控制资源集合对应的RS的处理：
当目标控制资源集合为通过UE参数配置指示时，在所述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
所述目标控制资源集合为通过UE参数配置指示，所述方法还包括：通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合、并且为所述标识为0的目标控制资源集合配置对应的QCL信息。
也就是说，本方式，需要获取控制资源集合标识为0、并且还需要对控制资源集合0配置对应的QCL信息。
比如，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET、并且为CORESET ID为0配置对应的QCL信息。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
本方式中，CORESET 0可以有RRC来配置(UE-specific configured)，这时候，网络明确指示QCL相关信息，CORESET 0上也可以传输UE-specific的PDCCH。
方式4、
本方式针对如何判断采用目标控制资源集合对应的RS的处理：
当目标控制资源集合为通过UE参数配置指示时，在所述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
其中，所述目标控制资源集合为通过UE参数配置指示，包括：
通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合，所述标识为0的目标控制资源集合的配置中携带TCI信息。
进一步地，在判断是否采用目标控制资源集合所对应的RS的时候，除了上述方案之外，还可以判断是否通过信令激活所述标识为0的目标控制资源集合对应的TCI信息；其中，所述TCI信息中至少指示QCL信息。
也就是，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET、并且CORESET 0的配置中携带TCI状态信息(TCI状态信息中可以含有Spatial RX Parameter)。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
或者，还可以为UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET、并且CORESET 0的配置中携带TCI状态信息(TCI状态信息中可以含有Spatial RX  Parameter)，并且通过信令激活CORESET对应的TCI-state(TCI-state指示了QCL信息)。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合时，所述方法还包括：网络侧为所述标识为0的控制资源集合配置对应的QCL信息。
本方式中，CORESET 0可以有RRC来配置(UE-specific configured)，这时候，网络明确指示QCL相关信息，CORESET 0上也可以传输UE-specific的PDCCH。
基于前述方案中，UE获取到所要使用的RS之后，测量RS所对应的PDCCH所对应的链路质量是否满足预定的门限。
具体来说，可以在波束失败恢复的流程(beam failure recovery)，或者是链路重配置流程(Link reconfiguration procedures)中使用该RS，比如，UE通过测量CSI-RS和/或SS/PBCH block来判断对应的PDCCH所对应的链路质量是否满足预定/配置的门限(Hypothetical BLER性能比门限差)；UE通过CSI-RS和/或SS/PBCH block来选择新的满足预定/配置门限的新的beam(L1-RSPR性能好于门限)；UE选择一个新的beam对应的PRACH发起传输，或者通过PUCCH上报其选择的新的beam；UE检测网络的响应。
需要进一步说明的是，里面提到的波束(Beam)，实际上是通过beam所承载的信号的信息来体现，在实际使用时，通过CSI-RS资源(resource)或者同步信号(SS)块/PBCH块block指示index来体现。
所述目标控制资源集合(CORESET)，用于使得UE在对应位置上检测PDCCH。目标CORESET可以包含时频资源(例如占用哪些频域资源，占用几个连续的时域符号)，以及其他一些配置，比如，天线端口QCL(quasi co-location)，QCL由高层参数TCI提供，该参数用于PDCCH接收的DM-RS 天线端口。
网络给UE配置了目标控制资源集合，所述目标控制资源集合与搜索空间相关联。进而，UE基于所述目标控制资源集合所关联的搜索空间进行对应位置上的PDCCH的检测。
本实施例提供的方案，可以参见图1进行详细说明：
步骤101：判断目标控制资源集合是否通过PBCH指示；若是，则执行步骤102；否则，执行步骤103；
步骤102：所述目标控制资源集合没有其他UE参数配置，则在所述UE需要确定用于测量的RS时，不采用目标控制资源集合所对应的RS，结束处理；
步骤103：当目标控制资源集合为通过UE参数配置指示时，在所述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
可见，通过采用上述方案，能够在所述UE需要确定用于测量的RS时，判断是否采用目标控制资源集合所对应的RS；如此，能够使得UE能够选取更符合需求的RS进行测量，从而提供系统效率。
实施例二、
本发明实施例提供了一种UE，如图2所示包括：
处理单元21，在所述UE需要确定用于测量的RS时，判断是否采用目标控制资源集合所对应的RS。
本实施例中，关于判断是否采用目标控制资源集合对应的RS的方式，可以参见以下说明：
方式1、
本方式针对如何判断不采用目标控制资源集合对应的RS的处理：
处理单元21，当目标控制资源集合为通过PBCH指示、且没有其他的UE参数配置时，在所述UE需要确定用于测量的RS时，不采用目标控制 资源集合所对应的RS。
本实施例中所述目标控制资源集合可以为控制资源集合CORESET 0，也就是标识为0的CORESET。
示例性的，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI等)。如果当前的CORESET 0是通过PBCH指示的，而没有其他的UE-specific configuration；则为了beam failure detection，当UE需要确定用于测量的RS时，不考虑CORESET 0对应的参考信号。
CORESET 0可以由PBCH指示的，UE在初始接入时，上传PRACH信号，网络通过接收到的PRACH信号，可以知道UE对应的SS/PBCH block是哪个，因此可以在这个对应的beam上发送在CORESET 0对应的资源上发送PDCCH。
方式2、
本方式针对如何判断采用目标控制资源集合对应的RS的处理：
处理单元21，当目标控制资源集合为通过UE参数配置指示时，在所述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
其中，所述目标控制资源集合为通过UE参数配置指示，包括：
所述UE还包括：
通信单元22，通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合。
也就是，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参 考信号。
本方式中，CORESET 0可以有RRC来配置(UE-specific configured)，这时候，网络明确指示QCL相关信息，CORESET 0上也可以传输UE-specific的PDCCH。
方式3、
本方式针对如何判断采用目标控制资源集合对应的RS的处理：
处理单元21，当目标控制资源集合为通过UE参数配置指示时，在所述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
所述目标控制资源集合为通过UE参数配置指示，通信单元22，通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合、并且为所述标识为0的目标控制资源集合配置对应的QCL信息。
也就是说，本方式，需要获取控制资源集合标识为0、并且还需要对控制资源集合0配置对应的QCL信息。
比如，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET、并且为CORESET ID为0配置对应的QCL信息。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
本方式中，CORESET 0可以有RRC来配置(UE-specific configured)，这时候，网络明确指示QCL相关信息，CORESET 0上也可以传输UE-specific的PDCCH。
方式4、

处理单元21，当目标控制资源集合为通过UE参数配置指示时，在所 述UE需要确定用于测量的RS时，采用目标控制资源集合所对应的RS。
其中，所述通信单元22，通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合，所述标识为0的目标控制资源集合的配置中携带TCI信息。
进一步地，在判断是否采用目标控制资源集合所对应的RS的时候，除了上述方案之外，还可以判断，通信单元22，通过信令激活所述标识为0的目标控制资源集合对应的TCI信息；其中，所述TCI信息中至少指示QCL信息。
也就是，UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET、并且CORESET 0的配置中携带TCI状态信息(TCI状态信息中可以含有Spatial RX Parameter)。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
或者，还可以为UE在当前状态下会monitor CORESET 0去接收PDCCH(例如UE可以自主决定去接收系统消息，RMSI，或者UE自己的数据等)。如果当前的CORESET 0是通过UE-specific configuration指示，例如通过RRC信令配置了CORESET ID为0的一个CORESET、并且CORESET 0的配置中携带TCI状态信息(TCI状态信息中可以含有Spatial RX Parameter)，并且通过信令激活CORESET对应的TCI-state(TCI-state指示了QCL信息)。为了beam failure detection，当UE需要确定用于测量的RS时，考虑CORESET 0对应的参考信号。
通过RRC信令获取网络侧配置的控制资源集合的标识为0的目标控制资源集合时，所述方法还包括：网络侧为所述标识为0的控制资源集合配 置对应的QCL信息。
