为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(Enhance Mobile Broadband，eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communication，URLLC)、大规模机器类通信(massive Machine Type Communication，mMTC)。
一方面，eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，例如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期 在LTE投资，提出了LTE和NR之间紧密配合(tight interworking)的工作模式。
为了能够尽快实现5G网络部署和商业应用，3GPP首先完成第一个5G版本，即LTE-NR双连接(LTE-NR Dual Connectivity，EN-DC)。在EN-DC中，LTE基站作为主节点(Master Node，MN)，NR基站作为辅节点(Secondary Node，SN)，连接演进型分组核心网(Evolved Packet Core network，EPC)。在R15后期，将支持其他双连接(Dual Connectivity，DC)模式，即NR-LTE双连接(NR-LTE Dual Connectivity，NE-DC)，5GC-EN-DC，NR DC。在NE-DC中，NR基站作为MN，LTE基站作为SN，连接5G核心网(5GC)。在5GC-EN-DC中，LTE基站作为MN，NR基站作为SN，连接5GC。在NR DC中，NR基站作为MN，NR基站作为SN，连接5GC。
NR也可以独立部署。NR将来会部署在高频上，为了提高覆盖，在5G中，通过引入波束扫描(beam sweeping)的机制来满足覆盖的需求(用空间换覆盖，用时间换空间)，如图2所示。在引入beam sweeping后，每个波束方向上都需要发送同步信号，5G的同步信号以同步信号块(SS/PBCH Block，SSB)的形式给出，包含主同步信号(Primary Synchronisation Signal，PSS)、辅同步信号(Secondary Synchronisation Signal，SSS)、和物理广播信道(Physical Broadcast Channel，PBCH)，如图3所示。5G的同步信号以同步信号突发组(SS burst set)的形式在时域上周期性出现，如图4所示，SS burst set的周期也可以称为SSB的周期。
每个小区的实际传输的波束(beam)个数通过网络侧配置来确定，但是小区所在的频点决定了可以配置最多的beam个数，如下表1所示。
频率范围 L(最多的beam个数)
(2.4)GHz以下 4
3(2.4)GHz—6GHz 8
6GHz—52.6GHz 64
表1
在无线资源管理(Radio Resource Management，RRM)测量中，测量的参考信号可以是SSB，即测量SSB中的SSS信号或者PBCH的解调参考信号(Demodulation Reference Signal，DMRS)信号来获取beam测量结果以及小区测量结果。此外，处于无线资源控制(Radio Resource Control，RRC)连接状态的终端设备还可以配置信道状态指示参考信号(Channel Status Indicator Reference Signal，CSI-RS)作为小区测量的参考信号。
对于基于SSB的测量，每个小区的SSB的实际传输位置可能不同，SS burst set的周期也可能不同。所以为了让终端设备在测量过程中节能，网络侧给终端设备配置SSB测量定时配置(SS/PBCH block measurement timing configuration，SMTC)，SMTC可以理解为SSB的测量窗口，终端设备只需 要在SMTC内进行测量，如图5所示。
由于每个小区实际传输的SSB的位置可能是不同的，所以为了让终端设备尽快能够找到实际传输的SSB的位置，网络侧还会给终端设备配置终端设备测量的实际的SSB传输位置，例如所有测量小区的SSB实际传输位置的并集，如下表2所示。作为示例，在3-6GHz时，bitmap的长度为8比特，假设8比特长度的bitmap为10100110，那么，终端设备只需要对8个SSB的候选位置中的SSB索引为0，2，5，6的SSB做测量。

表2
在一些移动性场景中，例如切换过程、主辅小区(Primary Secondary Cell，PSCell)添加过程，PSCell变更过程、辅小区(Secondary Cell，SCell)添加过程、SCell变更过程、重定向过程等，网络设备会给终端设备配置搜索目标小区时使用的SMTC，通过SMTC可以实现加快搜索到目标小区的目的。
然而，在网络设备没有为终端设备配置目标小区的SMTC的情况下，如何实现目标小区的快速搜索需要明确。为此，提出了本申请实施例的以下技术方案。
本申请实施例的技术方案中，在网络设备没有为终端设备配置目标小区的SMTC的情况下，使用RRM测量配置(以下称为第一测量配置)中和目标小区具有相同SSB频点和/或SSB子载波间隔的测量对象中配置的SMTC作为搜索目标小区使用的SMTC。
在RRM测量配置中，为了精细测量服务频点对应小区的测量，一个测量对象的配置中除了原有的SMTC以外，还会配置额外的SMTC，其中，额外的SMTC关联一个物理小区标识(Physical Cell Identity，PCI)列表，用于指示该频点哪些小区的测量可以使用该额外的SMTC。以下表3给出了NR频点的测量对象(measObjectNR)的配置内容，其中，“smtc1”对应于原有的SMTC，“smtc2”对应于额外的SMTC。

Figure PCTCN2021083674-appb-000003
表3
在一个测量对象的配置中配置有2个SMTC的情况下，使用哪一个SMTC作为目标小区搜索使用的SMTC需要明确。
图6是本申请实施例提供的确定SMTC的方法的流程示意图，如图6所示，所述SMTC的方法包括以下步骤：
步骤601：终端设备接收网络设备发送的第一RRC消息，所述第一RRC消息携带目标小区的配置信息；若所述目标小区的配置信息未包括目标小区的SMTC配置，则所述终端设备从第一测量配置中确定与所述目标小区具有关联关系的第一测量对象，所述第一测量对象关联第一SMTC配置和第二SMTC配置。
本申请实施例中，网络设备为接入网网元，可选地，网络设备可以是基站。
本申请实施例中，所述第一测量配置在所述第一RRC消息之前被所述终端设备接收。
在一些可选实施方式中，所述第一测量配置为RRM测量配置。RRM测量配置可以参照前述相关技术方案的描述。为便于理解，这里再对RRM测量配置进行一些说明，RRM测量配置包含一个或多个测量对象的配置，对于每个测量对象的配置来说，进一步包含SSB频点信息、SSB子载波间隔信息、以及1个或2个SMTC配置。需要说明的是，有些测量对象会关联1个SMTC配置(即测量对象的配置中包含1个SMTC配置)，而有些测量对象会关联2个SMTC配置(即测量对象的配置中包含2个SMTC配置，例如上述表3示意出2个SMTC配置的例子)。
本申请实施例中，SMTC配置用于确定测量SSB的时间窗口，可以将SMTC理解为SSB测量窗口，SMTC的描述也可以替换为SMTC窗口。在一些可选实施方式中，SMTC配置包括如下至少一种信息：SMTC的周期、SMTC的长度、SMTC的偏置。其中，SMTC的偏置用于确定SMTC的起 始位置。
需要说明的是，对于一个小区的测量(也即搜索)，是通过测量该小区的SSB来实现的。为了实现终端设备快速搜索目标小区，可以基于一个SMTC配置来搜索目标小区，具体地，终端设备根据SMTC配置在相应的SMTC内搜索目标小区对应的SSB。
本申请实施例中，在移动性场景下，网络设备为终端设备配置目标小区的配置信息，若所述目标小区的配置信息包括目标小区的SMTC配置，则终端设备根据该SMTC配置确定搜索目标小区使用的SMTC；若所述目标小区的配置信息未包括目标小区的SMTC配置，则所述终端设备从第一测量配置中确定与所述目标小区具有关联关系的第一测量对象，进而根据第一测量对象的SMTC配置确定搜索目标小区使用的SMTC。
以下对如何从第一测量配置中确定与所述目标小区具有关联关系的第一测量对象进行说明。
在一些可选实施方式中，所述第一RRC消息为RRC释放消息，所述RRC释放消息携带目标小区的SSB频点信息和/或SSB子载波间隔信息。所述终端设备根据所述目标小区的SSB频点信息和/或SSB子载波间隔信息，从第一测量配置中确定具有所述SSB频点和/或所述SSB子载波间隔的测量对象，作为第一测量对象。
在RRC重定向过程中，网络设备向终端设备发送RRC释放消息，RRC释放消息携带目标小区的配置信息，目标小区的配置信息例如有：目标小区的SSB频点信息、SSB子载波间隔信息。目标小区的配置信息中未包含SMTC配置的情况下，终端设备根据目标小区的SSB频点信息和/或SSB子载波间隔信息，从RRM测量配置中确定具有所述SSB频点和/或所述SSB子载波间隔的测量对象。在一个示例中，RRC释放消息中携带的内容参照以下表4。

Figure PCTCN2021083674-appb-000005
表4
参照表4，终端设备根据RRC释放消息中的以下信息路径获取到目标小区的SSB频点信息：
RedirectedCarrierInfo→CarrierInfoNR→carrierFreq。
参照表4，终端设备根据RRC释放消息中的以下信息路径获取到目标小区的SSB子载波间隔信息：
RedirectedCarrierInfo→CarrierInfoNR→ssbSubcarrierSpacing。
终端设备根据获取到的目标小区的SSB频点信息和/或SSB子载波间隔信息，确定RRM测量配置中具有相同频点和子载波间隔的测量对象，如MeasObjectNR。
在一些可选实施方式中，所述第一RRC消息为RRC重配置消息，所述RRC重配置消息携带目标小区的SSB频点信息和/或SSB子载波间隔信息。所述终端设备根据所述目标小区的SSB频点信息和/或SSB子载波间隔信息，从第一测量配置中确定具有所述SSB频点和/或所述SSB子载波间隔的测量对象，作为第一测量对象。
在切换过程(如NR PCell切换过程、NR PSCell切换过程)、或者NR PSCell添加过程、或者PSCell变更过程、或者SCell添加过程、或者SCell变更过程等场景下，网络设备向终端设备发送RRC重配置消息，RRC重配置消息携带目标小区的配置信息，目标小区的配置信息例如有：目标小区的SSB频点信息、SSB子载波间隔信息。目标小区的配置信息中未包含SMTC配置的情况下，终端设备根据目标小区的SSB频点信息和/或SSB子载波间隔信息，从RRM测量配置中确定具有所述SSB频点和/或所述SSB子载波间隔的测量对象。在一个示例中，RRC重配置消息携带的内容参照以下表5。
Figure PCTCN2021083674-appb-000006
表5
参照表5，终端设备根据RRC重配置消息中的以下信息路径获取到目标小区的SSB频点信息：
ServingCellConfigCommo→DownlinkConfigCommon→FrequencyInfoDL→absoluteFrequencySSB。
参照表5，终端设备根据RRC重配置消息中的以下信息路径获取到目标小区的SSB子载波间隔信息：
CellGroupConfig→SpCellConfig→ReconfigurationWithSync→ServingCe llConfigCommon→ssbSubcarrierSpacing。
终端设备根据获取到的目标小区的SSB频点信息和/或SSB子载波间隔信息，确定RRM测量配置中具有相同频点和子载波间隔的测量对象，如MeasObjectNR。
步骤602：所述终端设备从所述第一SMTC配置和所述第二SMTC配置中确定目标SMTC配置，所述目标SMTC配置用于确定搜索所述目标小区使用的SMTC。
本申请实施例中，终端设备可以通过以下方式确定目标SMTC配置。
方式一
在一些可选实施方式中，若所述目标小区的频点和原服务小区的频点相同和/或所述目标小区的物理小区标识PCI属于所述第二SMTC配置关联的PCI列表，则所述终端设备将所述第二SMTC配置确定为目标SMTC配置。若所述目标小区的频点和原服务小区的频点不同和/或所述目标小区的PCI不属于所述第二SMTC配置关联的PCI列表，则所述终端设备将所述第一SMTC配置确定为目标SMTC配置。
举个例子：以第一测量对象为MeasObjectNR为例，MeasObjectNR的配置信息包括smtc1配置和smtc2配置；如果目标小区的频点和收到RRC释放消息之前的服务小区的频点相同，和/或，目标小区的PCI在smtc2关联的PCI列表中，则使用MeasObjectNR中的smtc2作为目标SMTC；否则使用MeasObjectNR中的smtc1作为目标SMTC。
举个例子：以第一测量对象为MeasObjectNR为例，MeasObjectNR的配置信息包括smtc1配置和smtc2配置；如果目标小区的频点和源小区或者与原服务小区的频点相同，和/或，如果目标小区的PCI(即表5中的ServingCellConfigCommo中配置的PhysCellId)在smtc2关联的PCI列表中，则使用MeasObjectNR中的smtc2作为目标SMTC；否则使用MeasObjectNR中的smtc1作为目标SMTC。
需要说明的是，上述方案中，所述第二SMTC配置至少用于确定第二SMTC的周期，所述第一SMTC配置至少用于确定第一SMTC的周期，所述第二SMTC的周期小于所述第一SMTC的周期。
作为示例，第一SMTC对应于表3中的smtc1，第二SMTC对应于表3中的smtc2，smtc2的周期小于smtc1的周期，换句话说，smtc2的周期比smtc1的周期短，因此按照smtc2进行搜索可以更快找到目标小区。
本申请实施例中，终端设备通过上述方式确定出目标SMTC配置后，基于目标SMTC配置确定搜索目标小区使用的SMTC，并使用该SMTC搜索目标小区。
方式二
在一些可选实施方式中，所述终端设备默认将所述第一SMTC配置确定为目标SMTC配置。
这里，无论是何种移动性场景，如果网络设备没有配置目标小区的SMTC配置，则终端设备使用和目标小区具有相同SSB频点和SSB子载波间隔的测量对象中配置的smtc1对应的SMTC配置进行目标小区的搜索。
上述方案中，若所述终端设备从第一测量配置中未确定出与所述目标小区具有关联关系的第一测量对象，则所述终端设备按照默认的SMTC配置搜索所述目标小区。这里，默认的SMTC配置用于确定默认SSB周期，终端设备可以按照默认SSB周期搜索目标小区。作为示例，默认SSB周期例如为5ms。当然，默认SSB周期还可以是其他数值，协议可以规定默认SSB周期的数值。
本申请实施例的技术方案中，明确了终端设备如何根据SSB频点和SSB子载波间隔确定测量对象，进而根据测量对象的配置获取目标SMTC配置，实现了根据目标SMTC配置快速搜索目标小区的目的。
图7是本申请实施例提供的确定SMTC的装置的结构组成示意图，应用于终端设备，如图7所示，所述确定SMTC的装置包括：
接收单元701，用于接收网络设备发送的第一RRC消息，所述第一RRC消息携带目标小区的配置信息；
确定单元702，用于若所述目标小区的配置信息未包括目标小区的SMTC配置，则从第一测量配置中确定与所述目标小区具有关联关系的第一测量对象，所述第一测量对象关联第一SMTC配置和第二SMTC配置；从所述第一SMTC配置和所述第二SMTC配置中确定目标SMTC配置，所述目标SMTC配置用于确定搜索所述目标小区使用的SMTC。
