具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
图1是一种适用于本申请的通信系统的示意图。
通信系统100包括网络设备110、网络设备120和终端设备130。终端设备130可以与网络设备110和/或网络设备120进行通信。图1中的虚线表示网络设备的覆盖范围，双向箭头表示两个设备之间能够进行通信。例如，终端设备130可以通过电磁波与网络设备110和/或网络设备120进行通信，网络设备110与网络设备120之间也可以通过电磁波进行通信。
在本申请中，终端设备130可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，例如，第三代合作伙伴计划(3rd generation partnership project，3GPP)所定义的用户设备(user equipment，UE)，移动台(mobile station，MS)，软终端，家庭网关，机顶盒等等。
网络设备110和/或网络设备120可以是符合3GPP规范的接入网设备，例如，5G移动通信系统中的基站(gNB)。网络设备110和/或网络设备120也可以是非3GPP(non-3GPP)的网络设备，例如接入网关(access gateway，AGF)。网络设备110和/或网络设备120还可以是中继站、接入点、车载设备、可穿戴设备以及其它类型的设备。
通信系统100仅是举例说明，适用本申请的通信系统不限于此。
终端设备130可以通过DC与网络设备110和网络设备120通信。在DC中，多个小区组(cell group，CG)可以为终端设备服务，该多个CG可以包括主CG(master CG，MCG)和辅CG(secondary CG，SCG)，主CG也可以称为主基站，辅CG也可以称为辅基站。在本申请中，MCG、主基站以及主网络设备是等价的；类似地，SCG、辅基站以及辅网络设备是等价的；以下不再区分上述概念。
主基站提供主要的无线资源控制(radio resource control，RRC)控制功能以及通向 核心网的控制面；辅基站主要提供数据传输功能，可以提供辅助的信令，例如信令无线承载(signalling radio bearer，SRB)3。
基于主基站、辅基站和核心网等因素，可以将DC划分为多种类型。
当主基站为LTE基站，辅基站为NR基站，并且与主基站连接的核心网为演进型分组核心网(evolved packet core，EPC)时，DC可以称为演进的通用移动通信系统陆地无线接入网新无线-双连接(evolved universal mobile telecommunications system terrestrial radio access network new radio-DC，EN-DC)。
当主基站为LTE基站，辅基站为NR基站，并且与主基站连接的核心网为下一代核心网(next generation core，NGC)时，DC可以称为下一代核心网型EN-DC(NGEN-DC)。
当主基站为NR基站，辅基站为LTE基站时，并且与主基站连接的核心网为NGC时，DC可以称为新无线演进的通用移动通信系统陆地无线接入网-双连接(new radio evolved universal mobile telecommunications system terrestrial radio access network-DC，NE-DC)。
当主基站为NR基站，辅基站为NR基站时，并且与主基站连接的核心网为NGC时，DC可以称为NR-DC。
上述几种DC是适用于本申请的一些示例，适用于本申请的DC不限于此。
终端设备130还可以通过载波聚合(carrier aggregation，CA)与网络设备110和/或网络设备120通信。
终端设备130应用CA后，可以通过联合调度和使用多个成员载波(component carrier，CC)上的资源，使得通信系统可以支持更大的带宽，从而能够实现更高的系统峰值速率。根据CC的在频谱上的连续性可以将CA分为连续性CA和非连续性CA；根据CC所在的频带(band)可以将CA分为分为带内(intra-band)CA和带外(inter-band)CA。
按照通信系统支持的上下行业务的对称关系，CA可以分为不对称CA和对称CA，在不对称CA中，一定有下行CC，可以没有上行CC。对于主载波(primary cell component，PCC)小区来说一定有本小区的物理下行控制信道(physical downlink control channel，PDCCH)和物理上行控制信道(physical uplink control channel，PUCCH)，而且只有主载波小区有PUCCH，辅载波(secondary cell component，SCC)小区可能有PDCCH。
在CA中，PCC有且只有一个，PCC提供RRC信令连接以及非接入层(non-access stratum，NAS)功能等。通常情况下，PUCCH只存在于PCC上，SCC只提供额外的无线资源。
PCC和SCC统称为服务小区。通常情况下，CA中能够聚合的载波最多为5个，即聚合后的最大带宽为100MHz，并且各个CC属于同一个基站。所有的CC使用相同的小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)，基站保证每个CC所在的小区的C-RNTI不发生冲突。
在给终端设备130配置CA和DC之前，终端设备130需要对小区进行测量，例如，执行无线资源管理(radio resource management，RRM)测量。在RRM测量中，测量的 信号可以是同步信号/物理广播信道块(synchronisation signal/physical broadcast channel block，SSB)，即，可以通过测量SSB中的辅同步信号(secondary synchronisation signal，SSS)信号或者PBCH的解调参考信号(demodulation reference signal，DMRS)来获取波束测量结果以及小区测量结果。此外，处于RRC连接态的终端设备130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。
终端设备130在空闲态或者去激活态基于网络设备配置的测量参数执行测量并记录测量结果；在进入连接态之后，将测量结果上报给网络设备，辅助网络侧配置CA和DC。
下面先介绍上述几种状态，再介绍空闲态进行测量的过程。
空闲态(RRC_IDLE)：移动性为基于UE的小区选择重选，寻呼由核心网(core network，CN)发起，寻呼区域由CN配置。基站不存在UE AS上下文。不存在RRC连接。
连接态(RRC_CONNECTED)：存在RRC连接，基站和UE存在UE接入层(access stratum，AS)上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
去激活态(RRC_INACTIVE)：移动性为基于UE的小区选择重选，存在CN-NR之间的连接，UE AS上下文存在某个基站上，寻呼由RAN触发，基于RAN的寻呼区域由RAN管理，网络侧知道UE的位置是基于RAN的寻呼区域级别的。
网络侧可以控制终端设备的状态转换，如图2所示。
当终端设备处于去激活态时，在处于如下情况时终端设备自动进入空闲态：
接收到CN初始的寻呼消息时；
发起RRC恢复请求时，启动定时器T319，如果定时器超时；
MSG4完整性保护验证失败时；
小区重选到其他RAT时；
进入驻留任何小区(camp on any cell)状态。
去激活态的特征：
无线接入网(radio access network，RAN)和CN之间的连接是保持的；
UE和至少一个gNB保存AS上下文；
UE对于RAN侧来说是可达的，相关参数由RAN配置；
当UE在RAN配置的RAN内移动时不需要通知网络侧，但当移动出RAN时需要通知网络侧；
UE在RAN内移动按照小区选择重选方式。
空闲态进行测量的过程如下。
RRC释放消息可以配置空闲态下测量配置，系统广播SIB5也可以配置空闲态下测量配置。如果有专用配置则使用专用配置，否则使用SIB5中测量配置。SIB5中空闲态测量配置没有有效时间限制；专用信令中配置的空闲态测量配置同时也配置有有效时间 配置，即T331。T331超时或者停止，则释放专用信令中配置的空闲态测量配置，UE是否继续使用SIB5中空闲态测量配置，取决于UE实现。
空闲态下的测量配置获取后，UE执行测量，通过在UL消息中指示网络侧存在空闲态测量结果，然后基于基站请求方式进行上报。同时小区在SIB2中也会广播是否支持空闲态测量结果的上报。
空闲态测量配置信息如下：
SIB5和专用信令均包括measIdleCarrierListEUTRA，measIdleCarrierListEUTRA包括：carrierFreq、allowedMeasBandwidth、validityArea、measCellList、reportQuantities和qualityThreshold。
其中，carrierFreq和allowedMeasBandwidth指示了测量的频点和测量带宽；validityArea配置了空闲态测量配置的有效范围，是一个小区列表。如果UE重选到一个该validityArea之外的小区，则停止定时器T331。measCellList给出测量配置上报的小区，其他小区不用上报，如果该measCellList没有配置，则UE上报满足qualityThreshold的最多maxCellMeasIdle个小区的测量上报。上报的测量量通过reportQuantities指定。
下面介绍本申请提供的测量小区的方法。如图3所示，方法300包括：
S310，终端设备从第一小区接收第一测量配置，所述第一测量配置用于配置所述终端设备在空闲态和/或去激活态执行测量的配置信息。
可选地，上述第一测量配置承载于专用信令，该专用信令为无线资源控制释放RRCRelease消息。
可选地，第一测量配置承载于系统广播中。
可选地，方法300还包括：
在第一小区不支持多无线接入技术双连接(multi-RAT DC，MR-DC)的情况下，终端设备确定不执行与辅节点(secondary node，SN)RAT对应的频率的测量。
可选地，方法300还包括：
在第一小区支持MR-DC的情况下，终端设备执行第一测量配置的测量。
第一小区例如是当前服务小区，该当前服务小区例如是LTE小区，SN RAT例如是NR RAT。可选地，当前服务小区也可以是NR小区。
如果当前服务小区的系统广播指示LTE小区支持EN-DC，例如，upperLayerIndication指示true，则UE获取SIB中关于NR频率列表中NR频点的测量，否则不获取SN RAT的测量配置信息。
如果当前小区的系统广播指示当前LTE小区支持EN-DC，例如，upperLayerIndication指示true，则UE执行NR频率列表的NR频点的测量，否则不执行任何NR频点的early measurement的测量以及测量结果上报。
在上述方案中，终端设备根据当前服务小区以及SN RAT否支持MR-DC确定是否执行与SN RAT相关的测量，若当前服务小区以及SN RAT中的任何一个不支持MR-DC，则终端设备不测量SN RAT的频点；若当前服务小区和SN RAT均支持MR-DC，则终端 设备测量SN RAT的频点。上述方案能够避免终端设备做无用功，达到省电的效果。
可选地，当第二小区的RAT与所述第一小区的RAT相异时，所述终端设备确定不执行与第二小区相关的测量；或者，
当第二小区的RAT与所述第一小区的RAT相同时，所述终端设备执行与所述第二小区相关的测量。

第一小区例如是当前服务小区，第二小区例如是重选的小区。在上述方案中，终端设备根据重选的第二小区的RAT确定是否执行与所述第二小区相关的测量。若当前服务小区以及重选的小区中的任何一个不支持MR-DC，则终端设备不测量重选的小区的频点；若当前服务小区和重选的小区均支持MR-DC，则终端设备测量重选的小区的频点。上述方案能够避免终端设备做无用功，达到省电的效果。
可选地，终端设备接收的专用信令指示第一小区信息，所述第一小区信息包括小区频点信息和/或小区标识信息。
可选地，终端设备根据第一小区信息搜索小区并驻留。
可选地，所述终端设备离开无线资源控制RRC连接状态后，在最后一个服务小区接收系统广播信息，然后执行小区选择。
可选地，所述终端设备离开RRC连接状态后，在最后一个服务小区驻留，且当前小区没有广播earlymeasurement的相关配置信息，所述终端设备确定不发起系统信息SI请求，所述SI请求用于请求网络设备发送配置信息。
上述方案中，终端设备从RRC释放消息中获取的测量配置不完整，需要读取系统广播中的配置信息完善测量配置。终端设备可以主动发送SI请求，请求获取驻留小区的频点信息和/或小区标识信息，网络设备可以通过专用信令向终端设备发送驻留小区的频点信息和/或小区标识信息，以便于终端设备完善测量配置；终端设备无需盲目测量，从而达到了省电的效果。或者，终端设备进入空闲态或者去激活态后，优先驻留在当前服务小区，获取测量结果，然后再执行小区选择；终端设备无需发送SI请求，减小了信令开销，达到了省电的效果。或者，终端设备进入空闲态或者去激活态后，在最后一个服务小区驻留，且当前小区没有广播earlymeasurement的相关配置信息，终端设备确定不发起SI请求，等待网络设备在RRC释放前或者后主动发送earlymeasurement配置信息相关 的SIB，从而达到了省电的效果。
