下面对本申请实施例提供的测量和上报方法、装置、设备、系统及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、辅小区(Secondary Cell，SCell)的激活与休眠：
基于UE的异频L3测量上报，网络可以配置一些SCell，并直接将其带宽部分(Band Width Part，BWP)配置为休眠状态；SCell与SpCell(即主小区(Primary Cell，PCell)+主辅小区(Primary Secondary Cell，PSCell))必然在同一个DU里。
网络可以保证休眠SCell与SpCell是帧同步的。从UE接收来看，仅仅可能因为SCell与SpCell不共址，因路径传播时延带来一些同步误差，通常不超过33us(假设基站覆盖半径9km，站间同步误差3us)。
SCell休眠状态下，UE在休眠SCell里仍然需要进行周期和半静态的信道状态信息(Channel State Information，CSI)测量，L1(即层1)测量以及L3(即层3)测量；测量结果不在休眠SCell上进行上报，但需要在SpCell上，或未休眠的包含物理上行控制信道(Physical Uplink Control Channel，PUCCH)的SCell上，进行上报。
休眠SCell里不会进行任何数据收发，包括物理下行控制信道(Physical Downlink Control Channel，PDCCH)盲检，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)接收，以及物理随机接入信道(Physical Random Access Channel，PRACH)/物理上行共享信道(Physical Uplink Shared Channel，PUSCH)/PUCCH/探测参考信号(Sounding Reference Signal，SRS)的发送；如果SCell波束故障恢复(Beam Failure Recovery，BFR)过程发生波束失败，UE在对应的上行授权(UL grant)上发送PUCCH；如果没有UL grant，可以通过在SpCell或未休眠的PUCCH SCell上发送调度请求(Scheduling Request，SR)来请求UL grant。
SCell和SpCell的UL定时提前量(Timing Advance，TA)可以在同一个定时提前组(Timing Advance Group，TAG)内，也可以在不同的TAG内，但一个小区组(Cell Group,CG)内最多只包含2个TAG。TAG是包含至少一个服务小区的小区集合，服务小区可以是PCell，PSCell或SCell。由于同一个CG内的SCell和SpCell在同一个DU内，因此网络可以通过SpCell或未休眠的SCell上的媒体接入控制层控制信元(Media Access Control-Control Element，MAC CE)来更新SCell对应的TAG上的TA。一般来说，如果存在和SpCell不共址的一个SCell，则出于维护TA的目的，网络一般不会将该SCell去激活。
2、PSCell的去激活，以及去激活态下的L1测量
网络可以给UE配置一个未激活的PSCell，这个PSCell和激活的服务小区，即PCell可以不具有帧同步关系。
在未激活的PSCell上不需要执行L1测量，但是需要执行无线链路监控(Radio link monitoring，RLM)/波束失败侦测(Beam Failure Dection，BFD)测量；在未激活的PSCell上，UE如果发现波束失败，需要在无线资源控制(Radio Resource Control，RRC)层按照辅小区组(Secondary Cell Group，SCG)失败进行上报。
3、同频邻小区L1测量；
网络可以配置在一个来自于邻小区的同步信号块(Synchronization Signal Block，SSB)，作为当前服务小区的可用SSB，UE可以在对应的SSB上进行层1测量和层1参考信号接收功率(Layer 1 Reference Signal Received Power，L1-RSRP)的上报。
邻小区SSB的频点和服务小区的频点必须一致，且二者必须都在激活BWP的带宽内；对于只有Single FFT的UE，邻小区SSB和服务小区的SSB的接收定时误差需要保证小于循环前缀(Cyclic Prefix，CP)的长度。
4、条件切换
网络预先给UE配置切换条件；当UE判断条件满足时，UE发起切换，从一个小区切换到另一个小区；网络会提前对相应的数据承载进行数据转发(data forward)。
5、L3测量
L3测量本质上也是一种L1测量，一般也称为移动性测量；对比L1测量，L3测量的用途上有区别，L3测量主要用于邻小区发现，并进行L3切换等一系列移动性的网络决策。
对于L3测量，存在同频测量和异频测量。测量频点与服务小区完全相同时，可视为同频测量，否则视为异频测量。
对于L3测量，UE只需要测量SSB，且测量结果仅仅上报当前服务小区；服务小区与邻小区处于不同DU甚至不同集中单元(Centralized Unit，CU)时，只有L3数据可以互通，L1/L2数据不会互通。
在FR2，L3测量中UE会使用宽波束来保证小区发现(Cell identification)，这一波束与L1测量中UE使用的波束是不同的。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的测量和上报方法进行详细地说明。
目前，UE可以通过同频或异频的L1测量，确定L1小区质量并上报网络，以便于网络可以发起基于L1/L2的连接态移动性管理(RRM)事件，例如小区切换，小区重定向，SCG/SCell加载等。
(1)L1测量仅仅只能在激活的SpCell或SCell中进行。网络需要先配置并激活SpCell或SCell后，UE才能进行L1测量；尽管激活的SCell可以处于休眠状态，且处于休眠状态的SCell上不需要进行数据收发，只需要持续进行DL测量，但这样的机制仅仅只能用于当前协议版本支持的，SCell和SpCell处于同一DU下的情形，也就是，网络可以通过已激活小区的DL和UL链路进行TA管理，波束管理和功率管理。对于L1测量中，被测小区与服务小区处于不同DU下的情形，基于现有的L1测量和上报机制无法进行。
(2)L1测量需要网络先激活SCell后，才可以对对应小区进行测量，这样，对于尚未激活SCell的频点或UE BWP配置内，当前L1测量无法提前进行。
(3)L3测量主要用于小区发现和搜索，其性能要求和实现方式，与用于波束管理的L1测量完全不同，例如，L1测量使用的Rx波束增益一般都会高于L3测量；因此，L1测量与L3测量，其结果一般不能直接比较；因此，不适合使用L3测量的中间结果，即L1结果来完成充当邻小区的L1测量结果。
(4)条件切换中，网络的CU和DU之间可以做好切换准备，基于UE发送的随机接入信道(Random Access Channel，RACH)直接完成切换，但UE只能基于L3测量结果发起切换，也就是说，UE无法在未知小区上进行L1测量，而相应的L1上报也必须在条件切换完成后才能进行。
针对上述问题，本申请实施例中，当被测小区与服务小区处于不同DU时，UE可以根据网络侧配置的测量配置信息，进行L1测量，具体地，UE基于L1测量参考信号的带宽配置进行L1测量，以实现L1测量；并且，UE可以根据网络侧配置的上报配置信息，上报L1测量的测量结果，具体地，UE基于指示的目标小区集合进行上报，以实现L1测量上报；即本申请明确给出了UE进行L1测量是基于L1测量参考信号的带宽配置进行测量的，并且UE进行L1上报是基于目标小区集合上报的方案，如此，使得网络测设备能够根据UE基于L1测量参考信号的带宽配置和目标小区集合所上报的测量结果，以提前进行移动性管理和链路质量管理，使得UE能够进行高质量的数据传输，从而提升了UE的数据传输性能。
具体的，本申请实施例提供一种测量和上报方法，图2示出了本申请实施例提供的一种测量和上报方法的流程图。如图2所示，本申请实施例提供的测量和上报方法可以包括下述的步骤201至步骤204。

需要说明的是，第一指示信息用于指示UE进行L1测量上报对应的目标小区集合可以理解为：第一指示信息用于指示UE在目标小区集合上进行L1测量上报；或者，第一指示信息用于指示UE进行L1测量上报时的资源在目标小区集合上；或者，第一指示信息用于指示UE进行L1测量上报的测量结果是在目标小区集合中的小区的测量结果。
可选地，本申请实施例中，上述L1测量参考信号的带宽配置可以为系统带宽配置或BWP配置。
可选地，本申请实施例中，上述目标小区集合与网络侧设备的服务小区处于不同的DU下(即gNB MAC不同)。
可选地，本申请实施例中，网络侧设备可以通过RRC配置下发目标配置信息，以指示UE在一个或多个L1测量配置上进行L1测量，以及指示UE在一个或多个L1上报配置上进行L1测量结果的上报。
可选地，本申请实施例中，上述测量配置信息可以由第一参数集合唯一确定，上述上报配置信息可以由第二参数集合唯一确定。需要说明的是，这里的“唯一确定”意味着，当且仅当第一参数集合内的至少一项参数存在不一致时，上述测量配置信息/上报配置信息被区分成两个不同的配置。
可选地，本申请实施例中，上述第一参数集合还包括以下至少一项：
L1测量参考信号的资源配置；
L1测量参考信号对应的小区配置；
L1测量参考信号对应小区的上报配置。
可选地，本申请实施例中，上述L1测量参考信号的资源配置可以包括以下至少一项：频点、资源块(Resource Block，RB)分配、周期等。
可选地，本申请实施例中，上述L1测量参考信号对应的小区配置可以包括小区的物理小区标识(Physical Cell ID，PCID)；上述L1测量参考信号对应小区的上报配置可以包括小区集合指示。
可选地，本申请实施例中，上述第二参数集合还包括以下至少一项：
上报配置信息对应的小区集合指示；
上报配置信息对应的小区集合的TAG指示；
目标小区集合上配置的一个激活时间窗，该激活时间窗用于监听目标小区集合内下发的PDCCH；
目标小区集合上配置的至少一个PUCCH资源，该至少一个PUCCH资源用于上报波束测量结果和CSI信息；
目标小区集合上配置的SRS资源，该SRS资源用于发送SRS；以确定同步信息。
可选地，本申请实施例中，上述激活时间窗可以包括周期、系统帧号(System Frame Number，SFN)偏移量(offset)、时间窗长度中的至少一项；该激活时间窗可以通过搜索空间(search space)来配置，该激活时间窗可以用于监听目标小区集合内下发的PDCCH(这一调度信令对应的RNTI不是C-RNTI)。
可选地，本申请实施例中，上述PDCCH用于以下至少一项：
发送功率调整信息，该功率调整信息用于指示目标小区集合中的小区的L1测量上报的功率已调整；
通过下发PDCCH命令，触发UE执行发送RACH的过程(PDCCH order的RACH)；以便于对应小区上的TA维护；
发送用于调整TA的定时提前命令；
发送用于通知UE移动性状态发生变化的L1或L2信令。
可选地，本申请实施例中，上述定时提前命令(TA Command)可以为MAC CE或下行控制信息(Downlink Control Information，DCI)。
步骤203、UE根据测量配置信息进行L1测量，得到L1测量结果，并根据上报配置信息，向网络侧设备发送L1测量结果。
可选地，本申请实施例中，上述步骤203中的“UE根据测量配置信息进行L1测量，得到L1测量结果”具体可以通过下述的步骤203a实现。
步骤203a、UE根据测量配置信息，在L1测量频率层上对多个小区进行L1测量，得到L1测量结 果。
本申请实施例中，上述多个小区属于N个同步小区群组，每个同步小区群组内的各个小区间的下行接收定时同步误差满足预设条件，N为正整数。
可选地，本申请实施例中，上述预设条件可以为每个同步小区群组内，各个小区间的下行Rx定时同步误差不超过CP长度。
可选地，本申请实施例中，上述带宽配置为BWP。在第一小区的BWP与网络侧设备的服务小区的激活BWP不同的情况下，L1测量频率层为异频L1测量频率层，异频L1测量频率层对应的L1测量为测量间隔外的L1测量；在第一小区的BWP与服务小区的激活BWP相同的情况下，L1测量频率层为同频L1测量频率层。其中，第一小区为UE进行L1测量的小区，L1测量频率层为UE进行L1测量的频率层。
可以理解，当L1测量所处的小区BWP与服务小区的激活BWP没有交叠时，可视为一个异频L1测量频率层；；当L1测量所处小区的BWP在服务小区的激活BWP内时，可视为一个同频测量频率层。对于异频L1测量频率层，UE可以在L1测量在测量间隔(gap)外进行测量，也可以在测量间隔内进行测量。
可选地，本申请实施例中，在上述步骤203中的“根据上报配置信息，向网络侧设备发送L1测量结果”之前，本申请实施例提供的测量和上报方法还包括下述的步骤301。

其中，在建立上行同步后，邻小区对应的TAG处于激活状态。
可以理解，在UE将L1测量结果上报某一邻小区之前，UE需要在该邻小区上建立上行同步，例如通过发送上行信号并接收网络的反馈信令，以确定上行TA。
步骤204、网络侧设备接收UE发送的L1测量结果。
本申请实施例提供一种测量和上报方法，当被测小区与服务小区处于不同DU时，UE可以根据网络侧配置的测量配置信息，进行L1测量，具体地，UE基于L1测量参考信号的带宽配置进行L1测量，以实现L1测量；并且，UE可以根据网络侧配置的上报配置信息，上报L1测量的测量结果，具体地，UE基于指示的目标小区集合进行上报，以实现L1测量上报；即本申请明确给出了UE进行L1测量是基于L1测量参考信号的带宽配置进行测量的，并且UE进行L1上报是基于目标小区集合上报的方案，如此，使得网络测设备能够根据UE基于L1测量参考信号的带宽配置和目标小区集合所上报的测量结果，以提前进行移动性管理和链路质量管理，使得UE能够进行高质量的数据传输，从而提升了UE的数据传输性能。
可选地，本申请实施例中，在上述步骤201之前，本申请实施例提供的测量和上报方法还包括下述的步骤401和步骤402。

可以理解，网络侧设备可以基于UE上报的L1测量结果，下发目标信令(例如L1信令或L2信令)，对UE进行移动性管理，该移动性管理包括小区切换、小区重定向、SCG/SCell加载中的至少一项。
可选地，本申请实施例中，在上述步骤204之后，本申请实施例提供的测量和上报方法还包括下述的步骤601和步骤602。
步骤601、在UE在目标小区接收到切换信令的情况下，UE向源小区发送第二指示信息。
本申请实施例中，上述目标小区为UE待切换的小区，切换信令用于指示UE切换至目标小区，第二指示信息用于指示源小区停止数据发送。
可选地，本申请实施例中，上述目标小区的控制面承载在切换完成后激活；即针对切换场景，目标小区的控制面承载在L1/L2切换完成后激活。
步骤602、UE接收源小区发送的确认(Acknowledge，ACK)信息，并向目标小区发送切换完成的通知消息。
可以理解，UE在目标小区接收到L1切换信令后，UE可以通过L1/L2信令，通知源小区停止数据发送；并在接收到源小区发送的ACK信息后，向目标小区发送L1/L2信令以通知切换完成。
可选地，本申请实施例中，CU可以通过无线链路控制(Radio Link Control，RLC)数据包复制，向两个DU的RLC实体实时传输对应于UE的数据承载上的数据流，两个RLC实体根据相同的逻辑进行数据包的封包。
可选地，本申请实施例中，在L1/L2切换完成前，对应目标DU会抛弃UE的部分超时数据。
可选地，本申请实施例中，UE在回复目标DU，L1/L2切换完成时，可以携带上下行RLC数据包ACK编号信息。
可选地，本申请实施例中，上述L1/L2信令可以理解为BWP切换信令(类似SCell从休眠(Dormancy)状态退出)。
可选地，本申请实施例应用于小区间切换场景、小区重定向场景、SCG/辅小区加载场景等，这里以同一个CU下不同DU的小区间切换场景为例，对本申请实施例提供的测量和上报方法的具体过程进行说明。如图3所示，本申请实施例提供的测量和上报方法包括下述的步骤21至步骤28。
假设UE在源小区(即源小区DU)上正在进行数据传输，本申请可以通过如下步骤，以完成到目标小区的小区切换：
步骤21、源小区通过RRC重配消息，给UE配置L3测量事件。
本申请实施例中，上述L3测量事件的频点包含目标小区的SSB对应的频点。基于网络的L3测量事件配置，UE在对应的SSB频点上进行小区发现和L3测量。
步骤22、UE在发现目标小区并完成L3测量后，上报测量报告。
本申请实施例中，当目标小区的SSB满足UE可检测的条件时，也就是UE通过小区发现过程发现了目标小区时，UE可以进行L3测量，并将目标小区的测量结果上报给源小区，通过源小区DU转发给CU。
步骤23、源小区DU通过RRC重配消息，配置目标小区的待切换BWP，以使得UE根据配置的该BWP提前进行链路维护。
本申请实施例中，CU基于L3测量结果，将对应于另一个DU的目标小区配置为“待切换”小区，并为该小区配置一组处于“待切换”状态的DL BWP和UL BWP，也可以称为“休眠”BWP，以及关联到该BWP上的一些参考信号配置和上报配置，以方便UE进行链路维护。
需要说明的是，如果存在多于一个目标小区时，网络侧设备可以进一步配置一个目标小区集合，该目标小区集合内的所有小区属于同一DU，这些目标小区的待切换BWP的配置是完全一致的，即这些目标小区被称为目标小区集合。网络侧设备可以通过上报配置中的指示信息，指示UE在该目标小区集合对应的DU上进行L1测量上报。
示例性地，如图4所示，为本申请实施例提供的两个激活链路的示意图。针对目标小区的“休眠”BWP和源小区的激活BWP，待切换BWP的配置可以包括以下至少一项：PDSCH配置、PDCCH配置、PUSCH配置、PUCCH配置、必要的参考信号配置和QCL配置等，UE可以根据这些配置进行链路维护。
另外，L1测量配置(即上述测量配置信息)可以包括以下至少一项：
测量参考信号配置，例如频点、RB分配、周期等；
测量参考信号对应的小区配置，例如小区PCID等；
测量参考信号对应小区的上报配置，例如小区集合指示等。
需要说明的是，L1测量配置和上报配置都关联到某一待切换BWP，待切换BWP以及其对应的目标小区集合，相较于源目标小区集合，具有如下不同点：
(1)待切换BWP对应的PDCCH的监听是周期性的，存在一个周期和时间偏置的配置。这些PDCCH监听对应的搜索空间上，UE不需要基于C-RNTI来检测DCI；这些PDCCH下发的调度信令用于以下至少一项：
通知对应上报的功率调整信息；
触发PDCCH order的RACH，便于对应小区上的TA维护；
发送用于调整TA的TA Command，可以是MAC CE或DCI；
通知UE移动性状态变化的L1/L2信令。
(2)“待切换”BWP对应的小区或小区集合，会维护一个独立的TAG，即不同于激活小区的TAG；UE在接收到待切换BWP的配置之后，会在适当的时间向网络侧设备发送RACH，并在PDCCH激活时间内接受TA更新命令，包含PDCCH order，以维护TA，具体维护方方式包括以下至少一项：
通过发送上行信号，并接收网络的反馈信令，以确定上行TA；
网络基于PUCCH和/或SRS的发送，确定TA的调整量；
建立上行同步后，邻小区对应的TAG处于激活状态。
(3)待切换BWP上配置的CSI计算和上报，L1-RSRP计算和上报，可以直接按照待切换BWP对应的准共址(Quasi-Co-Location，QCL)信息，通过UL信道(PUSCH或PUCCH)发送到对应小区。
(4)如果目标小区的待切换BWP与服务小区的激活BWP没有交叠时，例如处于不同的预定义频段上时，可视为一个异频频率层；当L1测量所处小区的BWP在服务小区的激活BWP内时，可视为一个同频测量频率层。
其中，异频L1测量在测量间隔外进行；如果UE支持在L1异频测量频率层上进行CA或DC，则UE在该L1异频测量频率层上测量不需要测量间隔；CA或DC的UE能力是每个频带组合(per-Band Combination，per-BC)能力，即不同的频带组合，UE可以为该频带组合上报一个能力值。
每个L1测量频率层上，UE可以进行多于1个小区的L1测量，但多个小区只能属于N个同步小区群组；每个同步小区群组内，多个小区间的下行Rx定时同步误差不超过CP长度。UE支持的同步小区群组数目也是UE能力；这是一个per-band per-BC能力，即不同的频带组合，UE可以为该频带组合中的每一个频段上报一个能力值。
L1测量和上报，部分情况下也必须在测量间隔内进行，当网络配置的待切换BWP对应的同步小区群组大于UE能力时，或待切换BWP对应的TAG超出了UE可以支持的最大能力时，UE可以在测量 间隔内进行L1测量和上报；UE能够处理的最大激活TAG数目(含L1异频测量频率层对应的TAG)也是一个UE能力，可以是每个频率范围(per-Frequency range，per-FR)能力或per-UE能力，per-FR能力指的是UE为每个频率范围上报一个能力值，per-UE能力指的是UE上报的能力不区分频率范围，整个UE仅仅上报一个能力。
L1异频测量频率层数目是UE能力；per-UE/per-FR能力。
L1测量邻小区的数目是UE能力；per-UE/per-FR能力。
步骤24、UE发送RACH，建立与目标小区的连接并维护该连接，包括上行TA维护、上行功控、下行CSI反馈、下行波束测量上报等。
特别的，UE可以在监测到下行同步误差小于某一门限后，UE触发在对应的小区集合上发起CFRA，并建立起同步，开始反馈CSI和/或波束测量结果。
步骤25、目标小区DU通过MAC CE或DCI信令，同时激活目标小区的非“预切换”BWP以及其对应的传输配置指示(Transmission configuration Indication，TCI)。
本申请实施例中，目标小区DU同时激活目标小区的非“预切换”BWP以及其对应的TCI，能够使得UE可以在该BWP上以较好的质量进行上下行传输。
需要说明的是，这里较好的质量指的是：传输的速率较高(例如高于某一阈值)，或者，用于传输的MCS(Modulation and coding scheme，调制编码方案序号)和/或MIMO传输层数等较高(例如高于某一阈值)，或者，误码率和/或误块率较低(例如低于某一阈值)。
本申请实施例中，上述MAC CE或DCI信令，可以理解为BWP切换信令(类似SCell从Dormancy状态退出)。
步骤26、UE通过MAC CE上报源基站，因需要切换到目标DU，因此需要停止上下行发送。
步骤27、源小区DU通过MAC CE通知UE上下行发送已经停止。
步骤28、UE发送MAC信令，通知目标小区DU在源小区DU的RLC数据包发送情况，并完成切换。
其中，CU通过RLC数据包复制，向两个DU的RLC实体实时传输对应于UE的数据承载上的数据流，两个RLC实体根据相同的逻辑进行数据包的封包；
在L1/L2切换完成前，对应目标DU会抛弃UE的部分超时数据；
UE在回复目标DU，L1/L2切换完成时，会携带上下行RLC数据包ACK编号信息；
针对切换场景，目标小区的控制面承载，在L1/L2切换完成后激活；
至此，UE完成切换，开始在目标小区DU上进行数据传输。
需要说明的是，上述步骤25-步骤28是示例性的说明网络侧设备在接收到L1测量结果后，进行后续的L1/L2切换的过程，针对这个过程本申请实施例不做限制。
可以理解，对于异DU(Inter-DU)的邻小区，网络侧设备在为邻小区配置SSB测量的同时，给出了邻小区的一个类似休眠(dormant)的BWP配置，用于测量和上报。UE需要激活这个休眠BWP之后，将测量配置和上报配置关联到这个休眠BWP，并使用休眠BWP上配置的下行资源进行测量，使用休眠BWP上配置的上行资源进行L1测量上报。
这个邻小区的休眠BWP可以有独立的TAG配置；在休眠BWP上，UE需要进行L1测量和链路维护，包含RLM、BFD、TA维护、上行功率控制、CSI反馈等。UE可以按照一定的“激活时间窗”配置，在邻小区的休眠BWP上接收PDCCH，该PDCCH中接收的DCI不采用C-RNTI加扰，可以用于传输TA调整(含PDCCH order)、L1测量上报的上行功率控制、L1/L2小区切换信令(等同于BWP的激活/去激活信令)。
可以理解，休眠BWP上因为没有C-RNTI，所以不会传输实际的上下行数据承载对应的数据包；网络侧设备的CU可以传输数据包的两份复制到两个独立的DU，在完成目标小区的非休眠(non-dormant)BWP的激活后，才开始传输数据承载对应的数据包。激活目标小区的非休眠BWP前，目标小区DU从CU或UE处获得当前数据包承载传输情况(例如，UE上报DL/UL的RLC数据包ACK 序号)。
需要说明的是，如果休眠BWP的带宽完成处于当前激活BWP的带宽内，或二者完全相同，则记录该测量为同频L1测量；否则记为异频L1测量。UE在休眠BWP上的测量行为取决于UE的能力，即上述能力信息。
本申请实施例中，针对异频DU场景，UE可以在切换前提前完成邻小区的测量，并完成重要的邻小区链路维护过程，这样在切换后，无需基于一系列冗长的过程来获得新服务小区的CSI等重要信息，可以直接进行高质量的数据传输。
需要说明的是，本申请实施例提供的测量和上报方法，执行主体还可以为测量和上报装置，或者，该测量和上报装置中用于执行测量和上报方法的控制模块。
