Description

下行参考信号处理方法、装置及可读存储介质
本申请要求于2020年04月10日提交中国专利局、申请号为2020102815500、申请名称为“下行参考信号处理方法、装置及可读存储介质”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，尤其涉及一种下行参考信号处理方法、装置及可读存储介质。
背景技术
在非授权频谱中，基站仅仅在侦听到信道空闲时，才能够发送下行信号。当基站配置用户设备(User Equipment，UE)监听类型3-物理下行控制信道公共搜索空间(Type3-Physical Downlink Control Channel Common Search Space，Type3-PDCCH CSS)或DCI format 2-0，且UE检测到Type3-PDCCH CSS或DCI format 2-0时，UE通过下行控制信息(Downlink Control Information，DCI)内容可以知道信道占据时间(Channel Occupancy Time，COT)的信息，从而确定半静态配置的CSI-RS在COT内是有效的。实际上，UE还要根据DCI format 2-0中的时隙格式指示(Slot Format Indicator，SFI)信息，确定半静态配置的CSI-RS是否被SFI所“取消”(canceled)，比如SFI指示某个符号是上行符号，那么该符号上的CSI-RS被取消。但是，当基站没有配置UE监听DCI format 2-0，UE也就无法知道COT的信息，也就无法确定半静态配置的CSI-RS是否有效。这种情形例如：基站无法通过广播信令给空闲态UE配置DCI format 2-0(一般来说，基站只能通过专用RRC信令给UE配置DCI format 2-0)。当基站配置UE监听DCI format 2-0，但某些时候即使有信号发送也不发送DCI format 2-0，UE也就无法知道COT的信息，也就无法确定半静态配置的CSI-RS是否有效。这种情形例如：基站采用类型2或类型2A的下行信道接入过程(Type2/2A downlink channel access procedure)或先听后说类型2(Listen Before Talk Category 2，LBT Cat 2)发送发现突发(discovery burst，其中发现突发至少包含同步信号块，可以包含调度SIB1的PDCCH和承载SIB1的PDSCH和/或CSI-RS)，但不包含DCI format 2-0。

本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例，例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，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。
在非授权频谱中，若基站没有配置UE监听DCI format 2-0，或者UE未检测到DCI format 2-0时，UE如何确定半静态配置的CSI-RS是否有效，是亟待解决的问题。为解决该问题，本申请实施例提供一种下行参考信号处理方法、装置及可读存储介质。
本申请实施例提供的下行信号处理方法核心构思在于：通过确定UE是否被配置监听第一类PDCCH，确定下行参考信号是否有效，或者，通过接收下行信号或监听PDCCH或者监听同步信号块占用的时域资源，并根据接收的下行信号或监听PDCCH或者监听同步信号块占用的时域资源，以及高层信令配置的下行参考信号占用的时域资源，确定下行参考信号是否有效，通过上述方式减小了UE的复杂度，优化系统开销。
在本方案中，该下行参考信号可以是用于测量用途，例如为信道状态信息参考信号(Channel State Information–Reference Signal，CSI-RS)。该下行参考信号是有效的等同于下行参考信号是存在的(existing，present，presence)，或者可用的(useful)，或者需要测量的。UE确定下行参考信号在某段时间内有效的也等价于UE确定下行参考信号某段时间外是无效的，或者UE不期望参考信号某段时间外是有效的，或者UE在某段时间外是不需要测量下行参考信号。
以下，对本申请实施例的示例性应用场景进行介绍。
本申请实施例提供的下行参考信号处理方法可以通过本申请实施例提供的下行参考信号处理装置执行，本申请实施例提供的下行参考信号处理装置可以是用户设备的部分或者全部。图1是本申请实施例示例性的一种应用场景的示意图。如图1所示，该通信系统100包括：网络设备101和用户设备102。网络设备101和用户设备102可以使用一个或多个空口技术进行通信。

需要说明的是，以下实施例中，均以下行参考信号为CSI-RS为例进行详细说明。
图2为本申请一实施例提供的下行参考信号处理方法的流程图。该方法可以由本申请实施例提供的下行参考信号处理装置执行，该装置可以通过软件和/或硬件的方式实现，例如：该装置可以是上述用户设备的部分或全部，下面以用户设备为执行主体对下行参考信号处理方法进行说明，如图2所示，本申请实施例中的方法可以包括：
S101、确定下行参信号有效或者无效。
一种可能的实现方式，UE可通过确定UE是否被配置监听第一类PDCCH，确定下行参考信号是否有效。
可选地，第一类PDCCH为由时隙格式指示-无线网络临时标识(Slot Format Indication-Radio Network Tempory Identity，SFI-RNTI)加扰的类型3-PDCCH。第一类PDCCH通常采用DCI format 2-0。第一类PDCCH又可以称为携带DCI format 2-0的SFI-RNTI加扰的PDCCH。
具体地，若UE未被配置为监听第一类PDCCH，则确定下行参考信号无效；若UE被配置为监听第一类PDCCH，但UE未检测到PDCCH，则确定下行参考信号无效。也就是说，UE未被配置为监听DCI format 2-0的情况下，则确定CSI-RS无效；UE被配置为监听DCI format 2-0，但未检测到DCI format 2-0的情况下，则确定CSI-RS无效。
上述方式能够实现UE确定下行参考信号是否有效，且能够减小UE的复杂度，优化系统开销。
另一种可能的实现方式，UE可通过接收PDSCH或者监听PDCCH或者监听同步信号块，并根据接收的PDSCH或者检测的PDCCH或者检测到的同步信号块占用的时域资源与下行参考信号占用的时域资源，确定下行参考信号是否有效。
通过上述方式能够实现UE确定下行参考信号是否有效，还能够减小UE的复杂度，优化系统开销。
下面通过几个具体的实施例，对上述通过接收PDSCH或者监听PDCCH或者监听同步信号块，确定下行参考信号是否有效的具体实现方式进行详细介绍。
实施例二
图3为本申请另一实施例提供的下行参考信号处理方法的流程图。本实施例中，UE通过监听PDCCH，并根据检测到的PDCCH确定下行参考信号CSI-RS是否有效。如图3所示，本实施例的方法包括：
S201、监听PDCCH。
S202、根据检测到的PDCCH，确定下行参考信号是否有效。
在一些情况下，即使UE没有被配置为监听DCI format 2-0，或者，UE被配置为监听DCI format 2-0，但未检测到DCI format 2-0，UE依然能够确定CSI-RS是否有效。根据下行传输突发的定义，当一组来自基站的下行传输突发没有大于16微秒的间隔，那么这一组下行传输为一个下行传输突发。当假设一个下行传输突发内基站是占据信道的，那么，UE可根据下行传输突发确定CSI-RS是否有效。所述CSI-RS可以为周期(Periodic)或半持续(Semi Persistent)的CSI-RS。周期或半持续的CSI-RS可以是预先配置好的，比如半静态配置的、半静态配置动态激活的。
通常UE需要监听PDCCH，那么，UE可根据检测到的PDCCH与CSI-RS是否属于同一下行传输突发，确定CSI-RS是否有效。
一种可能的实现方式，若UE检测到的PDCCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源，小于或等于预设时间，则确定UE检测到的PDCCH与CSI-RS属于同一下行传输突发，即CSI-RS有效。若检测到的PDCCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号之间的时间间隔大于预设时间，则确定所述CSI-RS无效；其中，所述预设时间是根据下行传输突发确定的。
可选地，该预设时间为16微秒。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源与所述CSI-RS占用的时域资源连续，则确定所述CSI-RS有效；若检测到的PDCCH占用的时域资源与所述CSI-RS占用的时域资源不连续，则确定所述CSI-RS无效。
在一个正交频分复用(Orthogonal Frequency Division Modulation，OFDM)系统中，连续符号间的时间间隔可视为零，因此，上述方式也可以理解为，如果UE检测到一个PDCCH，那么UE可以确定CSI-RS与该PDCCH(或该PDCCH对应的CORESET)属于同一个下行传输突发或者CSI-RS是有效的，其中，该CSI-RS与该PDCCH(或该PDCCH对应的CORESET)是符号连续的。符号连续也可以理解为时域资源或时域符号是连续的。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源中最后一个OFDM 符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的PDCCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的PDCCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的PDCCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的PDCCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
也就是说，PDCCH与CSI-RS之间可以有X个符号的时间间隔，基站可以通过发送保留信号(Reserved signal)或其他的信号/信道来占据信道。因此，如果UE检测到一个PDCCH，那么UE可以确定CSI-RS与该PDCCH(该PDCCH对应的CORESET)属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该PDCCH(或该PDCCH对应的CORESET)(的结束)的时间间隔小于X个符号，X为正整数。
本文中，检测到的PDCCH占用的时域资源可以理解为检测到的PDCCH所属的控制资源集(Control Resource set，CORESET)或检测到的PDCCH所属的控制资源集的时域资源。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源存在至少部分相同的时域资源，则确定CSI-RS有效；若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源不存在相同的时域资源，则确定CSI-RS无效。
也就是说，一个CSI-RS可以使用PDCCH(或PDCCH对应的CORESET)中的一个符号，也就是说CSI-RS与PDCCH(或PDCCH对应的CORESET)是频分复用的(Frequency Division Multiplexed，FDM)，此时CSI-RS与PDCCH(或PDCCH对应的CORESET)也属于一个下行传输突发。因此，如果UE检测到一个PDCCH，那么UE可以确定CSI-RS与该PDCCH(或该PDCCH对应的CORESET)属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该PDCCH(或该PDCCH对应的CORESET)至少具有一个相同的符号。
上述任一种实现方式中，PDCCH可以属于类型0-物理下行控制信道公共搜索空间(Type0-Physical Downlink Control Channel Common Search Space，Type0-PDCCH CSS)，主要用于调度系统信息块1(System Information Block，SIB1)的物理下行共 享信道(PDSCH Physical Downlink Share Channel，PDSCH)；或者，可以属于类型1-物理下行控制信道公共搜索空间(Type1-Physical Downlink Control Channel Common Search Space，Type1-PDCCH CSS)，主要用于调度随机接入响应(Random Access Response，RAR)的PDSCH；或者，可以是类型2-物理下行控制信道公共搜索空间(Type2-Physical Downlink Control Channel Common Search Space，Type2-PDCCH CSS)，主要用于调度寻呼消息(paging message)的PDSCH；或者，可以属于UE指定搜索空间(UE specific Search Space，USS)，主要用于调度单播(unicast)的PDSCH。本申请不限制PDCCH的类型。
在另一些情况下，可认为检测到的PDCCH与CSI-RS在一个时隙(slot)内，则该CSI-RS与检测到的PDCCH属于一个下行传输突发。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源处于同一时隙，则确定所述CSI-RS有效；若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源不处于同一时隙，则确定CSI-RS无效。
也就是说，若UE检测到的PDCCH与CSI-RS属于同一时隙，则UE可以确定检测到的PDCCH与CSI-RS属于同一下行传输突发，则进一步确定CSI-RS有效。
另一种可能的实现方式，若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源处于同一时隙的前半时隙或后半时隙，则确定CSI-RS有效；若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源不处于同一时隙的前半时隙或后半时隙，则确定CSI-RS无效。
对于高频段上的非授权频谱，下行传输突发可能小于一个时隙，例如半个时隙，(从符号0开始至符号6，或者从符号7开始至符号13)。因此，UE可根据检测到的PDCCH与CSI-RS是否处于同一个半时隙，该半时隙可以为前半时隙或后半时隙，确定CSI-RS是否有效。具体地，若UE检测到的PDCCH与CSI-RS处于同一个半时隙，则确定CSI-RS有效；若UE检测到的PDCCH与CSI-RS不处于同一个半时隙，则确定CSI-RS无效。
在另一些情况下，可以认为CSI-RS与检测到的PDCCH在多个时隙或多个半时隙内的话，CSI-RS与PDCCH属于一个下行传输突发。相应地，UE可以确定CSI-RS是否有效。检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源处于相同的多个时隙或多个半时隙，则确定所述CSI-RS有效；若检测到的PDCCH占用的时域资源与CSI-RS占用的时域资源不处于相同的多个时隙或多个半时隙，则确定CSI-RS无效。这样可以在时隙持续时间较短时，增加总的COT持续时间。
上述确定方法中，还可以包括UE判断CSI-RS在频域上是否有效。上述确定方法中，仅当CSI-RS的资源限制在资源块集合(Resource Block Set，RB-set)中时，UE才确定CSI-RS有效，否则，确定CSI-RS无效，其中CSI-RS所述资源块集合与检测到的PDCCH所属的控制资源集有重叠。
本实施例中，UE通过检测PDCCH，并根据检测到的PDCCH占用的时域资源与高层信令配置的下行参考信号占用的时域资源之间的关系，确定下行参考信号是否有效，通过本实施例的方法，能够减小系统的复杂度。
实施例三
图4为本申请另一实施例提供的下行参考信号处理方法的流程图。本实施例中，UE通过接收PDSCH，并根据接收的PDSCH确定下行参考信号CSI-RS是否有效。如图4所示，本实施例的方法包括：
S301、接收PDSCH。
S302、根据接收的PDSCH，确定下行参考信号是否有效。
在一些情况下，UE可以被调度接收PDSCH，则UE可根据接收的PDSCH占用的时域资源，确定PDSCH与CSI-RS是否属于同一个下行传输突发，即确定CSI-RS是否有效。
一种可能的实现方式，若接收的PDSCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号之间的时间间隔小于或等于预设时间间隔，则确定CSI-RS有效；若接收的PDSCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号之间的时间间隔大于预设时间间隔，则确定CSI-RS无效；其中，预设时间间隔是根据下行传输突发确定的。
可选地，预设时间间隔为16微秒。
也就是说，如果UE(被调度去)接收一个PDSCH，那么UE可以确定CSI-RS与该PDSCH属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该PDSCH(的结束)时间间隔不大于16微秒。
另一种可能的实现方式，若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源连续，则确定CSI-RS有效；若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源不连续，则确定CSI-RS无效。
也就是说，如果UE(被调度去)接收一个PDSCH，那么UE可以确定CSI-RS与该PDSCH属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该PDSCH的符号是连续的。

另一种可能的实现方式，若接收的PDSCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若接收的PDSCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若接收的PDSCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若接收的PDSCH占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若接收的PDSCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若接收的PDSCH占用的时域资源中第一个OFDM符号与CSI-RS占用的时域 资源中第一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
也就是说，如果UE(被调度去)接收一个PDSCH，那么UE可以确定CSI-RS与该PDSCH属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该PDSCH(的结束)的时间间隔小于X个符号，X为正整数。
另一种可能的实现方式，若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源存在至少部分相同的时域资源，则确定CSI-RS有效；若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源不存在相同的时域资源，则确定CSI-RS无效。
也就是说，如果UE(被调度去)接收一个PDSCH，那么UE可以确定CSI-RS与该PDSCH属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该PDSCH至少具有一个相同的符号。
也就是说，如果UE(被调度去)接收一个PDSCH，那么UE可以确定CSI-RS与该PDSCH属于同一个下行传输突发或者CSI-RS是有效的，其中该PDSCH与该CSI-RS有重叠。
上述任一种可能的实现方式中，PDSCH可以为SIB1的PDSCH；或者，可以为RAR的PDSCH；或者，可以为寻呼消息(paging message)的PDSCH；或者，可以为调度单播的PDSCH。这里不限制PDSCH的类型。
在另一些情况下，可认为接收的PDSCH与CSI-RS在一个时隙(slot)内，则该CSI-RS与接收的PDSCH属于一个下行传输突发。
另一种可能的实现方式，若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源处于同一时隙，则确定CSI-RS有效；若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源不处于同一时隙，则确定CSI-RS无效。
也就是说，若UE接收的PDSCH与CSI-RS属于同一时隙，则UE可以确定接收的PDSCH与CSI-RS属于同一下行传输突发，则进一步确定CSI-RS有效。
另一种可能的实现方式，若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源处于同一时隙的前半时隙或后半时隙，则确定CSI-RS有效；若接收的PDSCH占用的时域资源与CSI-RS占用的时域资源不处于同一时隙的前半时隙或后半时隙，则确定CSI-RS无效。
对于高频段上的非授权频谱，下行传输突发可能小于一个时隙，例如半个时隙，(从符号0开始至符号6，或者从符号7开始至符号13)。因此，UE可根据接收的PDSCH与CSI-RS是否处于同一个半时隙，该半时隙可以为前半时隙或后半时隙，确定CSI-RS是否有效。
具体地，若UE接收的PDSCH与CSI-RS处于同一个半时隙，则UE可以确定CSI-RS与该接收的PDSCH属于同一下行传输突发，则确定CSI-RS有效；若UE接收的PDSCH与CSI-RS不处于同一个半时隙，则UE可以确定CSI-RS与该接收的PDSCH属于同一下行传输突发，则确定CSI-RS无效。

实施例四
图5为本申请另一实施例提供的下行参考信号处理方法的流程图。本实施例中，UE通过监听同步信号块，并根据检测到的同步信号块确定下行参考信号CSI-RS是否有效。参照图5所示，本实施例的方法包括：
S401、监听同步信号块。
S402、根据检测到的同步信号块，确定下行参考信号是否有效。
在一些情况下，UE需要监听同步信号块，因此，可根据检测到的同步信号块来确定一个下行传输突发，确定CSI-RS是否有效。
一种可能的实现方式，若检测到的同步信号块占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号之间的时间间隔小于或等于预设时间间隔，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号之间的时间间隔大于预设时间间隔，则确定CSI-RS无效；其中，预设时间间隔是根据下行传输突发确定的。
可选地，预设时间间隔为16微秒。
也就是说，如果UE检测到一个同步信号块，那么UE可以确定CSI-RS与该同步信号块属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该同步信号块(的结束)时间间隔不大于16微秒。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源连续，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源不连续，则确定CSI-RS无效。
在正交频分复用(Orthogonal Frequency Division Modulation，OFDM)系统中，连续符号间的时间间隔可视为零，因此，上述方式也可以理解为，若UE检测到一个同步信号块，那么UE可以确定CSI-RS与该同步信号块属于同一个下行传输突发或者CSI-RS是有效的，其中，该CSI-RS与该同步信号块是符号连续的。符号连续也可以理解为时域资源或时域符号是连续的。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源中最后一个OFDM符号与CSI-RS占用的时域资源中最后一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔小于预设阈值，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源中第一个OFDM符号与CSI-RS占用的时域资源中第一个OFDM符号的间隔大于或等于预设阈值，则确定CSI-RS无效。
也就是说，同步信号块与CSI-RS之间可以有X个符号的时间间隔，基站可以通过发送保留信号(Reserved signal)或其他的信号/信道来占据信道。因此，如果UE检测到一个同步信号块，那么UE可以确定CSI-RS与该同步信号块属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该同步信号块(的结束)的时间间隔小于X个符号，X为正整数。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源存在至少部分相同的时域资源，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源不存在相同的时域资源，则确定CSI-RS无效。
一个CSI-RS可以使用同步信号块(一般4个符号)中的一个符号，也就是说CSI-RS与同步信号块是频分复用的(Frequency Division Multiplexed，FDM)，此时CSI-RS与同步信号块也属于一个下行传输突发。因此，如果UE检测到一个同步信号块，那么UE可以确定CSI-RS与该同步信号块属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该同步信号块至少具有一个相同的符号。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源处于同一时隙，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源不处于同一时隙，则确定CSI-RS无效。
在某些情形下，如Type0-PDCCH监听时机与候选同步信号块索引关系中变量M＝1或2，或者变量O＝2或5或7时，同步信号块可以与Type0-PDCCH不在一个时隙中，此时基站可以在同步信号块的时隙中发送CSI-RS。这样的话，如果UE检测到一个同步信号块，那么UE可以确定CSI-RS与该同步信号块属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该同步信号块属于同一个时隙。
另一种可能的实现方式，若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源处于同一时隙的前半时隙或后半时隙，则确定CSI-RS有效；若检测到的同步 信号块占用的时域资源与CSI-RS占用的时域资源不处于同一时隙的前半时隙以及后半时隙，则确定CSI-RS无效。
也就是说，如果UE检测到一个同步信号块，那么UE可以确定CSI-RS与该同步信号块属于同一个下行传输突发或者CSI-RS是有效的，其中该CSI-RS与该同步信号块属于同一个半时隙，该半时隙例如为前半时隙或后半时隙。
在上述任一种可能的实现方式中，由于同步信号块仅仅在发现突发发送窗口(discovery burst transmission window)内发送，所以上述方式可以限制在突发发送窗口内。
在另一些情况下，可以认为CSI-RS与检测到的同步信号块在多个时隙或多个半时隙内的话，CSI-RS与同步信号块属于一个下行传输突发。相应地，UE可以确定CSI-RS是否有效。若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源处于相同的多个时隙或多个半时隙，则确定CSI-RS有效；若检测到的同步信号块占用的时域资源与CSI-RS占用的时域资源不处于相同的多个时隙或多个半时隙，则确定CSI-RS无效。这样可以在时隙持续时间较短时，增加总的COT持续时间。
上述确定方法中，还可以包括UE判断CSI-RS在频域上是否有效。上述确定方法中，仅当CSI-RS的资源限制在资源块集合(Resource Block Set，RB-set)中时，UE才确定CSI-RS有效，否则，确定CSI-RS无效，其中所述资源块集合与检测到的同步信号块有重叠。
上述确定方法中，可以进一步限定，UE仅仅确定与同步信号块有拟共站址(Quasi Colocation，QCL)关系的CSI-RS有效。其中，QCL关系可以为类型A-拟共站址(TypeA Quasi Colocation，TypeA QCL)关系、或类型B-拟共站址(TypeB Quasi Colocation，TypeB QCL)关系、或类型C-拟共站址(TypeC Quasi Colocation，TypeC QCL)关系、或类型D-拟共站址(TypeD Quasi Colocation，TypeD QCL)关系、或相等的平均接收功率(average receive power)等。这样，UE仅仅可以判定的与检测到的同步信号块具有波束方向关系的CSI-RS是否有效，减小UE复杂度。
本实施例中，UE通过监听同步信号块，并根据检测到的同步信号块占用的时域资源与高层信令配置的下行参考信号占用的时域资源之间的关系，确定下行参考信号是否有效，通过本实施例的方法，能够减小UE的复杂度，优化系统开销。
在实际应用中，上述各实施例的方法可以单独使用，也可以结合使用，本申请实施例对此不作限制。
