技术领域
本申请涉及通信技术领域，尤其涉及一种测量方法及设备。
背景技术
在通信系统中，由于终端设备的移动性，为了保证终端设备的业务连续性和通信质量，处于无线资源控制(radio resource control，RRC)空闲态(简称为RRC_idle态)和RRC非激活态(简称为RRC_inactive态)的终端设备通常需要进行无线资源管理(radio resource management，RRM)测量，从而实现小区重选(reselection)，从而改变其驻留的小区以获得连续不断的服务。其中RRM测量即为小区测量，其具体包括同频测量、异频/异系统测量。
为了保证终端设备能够实现小区重选，通信系统中管理小区的基站通常会在系统消息中携带该小区的测量配置信息。其中，所述测量配置信息可以但不限于包括以下测量配置参数：该小区所在频点的优先级、启动RRM测量的门限等。终端设备接收到服务小区的系统消息，以及管理服务小区的基站通知的目标频点(包含同频频点和/或异频频点)，就会根据其中的测量配置信息对所述目标频点上的邻区执行RRM测量，并根据测量结果进行小区重选。
其中，在终端设备执行RRM测量过程中，根据目标频点的优先级与服务频点(服务小区所在的频点)的优先级的相对关系，终端设备可以将目标频点分为以下三类：
高优先级目标频点，即优先级高于服务频点的优先级的目标频点。
同等优先级目标频点，即优先级与服务频点的优先级相同的目标频点。
低优先级目标频点，即优先级低于服务频点的优先级的目标频点。
由于在高优先级的目标频点上的邻区能够提供更好的服务，通信系统针对不同类目标频点设置的小区RRM测量触发条件不同，相应的针对不同类目标频点设置的小区重选规则也不同，这样可以使所述终端设备能够优先重选到在高优先级目标频点上的邻区，从而提高终端设备的服务质量。
由于目前处于RRC空闲态和RRC非激活态的终端设备执行上述RRM测量和小区重选是其功耗的主要来源，为了既可以保证终端设备的通信性能，还可以有效地节省终端设备的功耗，通信领域引出了放松RRM测量的概念，但是还未讨论实现放松RRM测量的方案。

具体实施方式
本申请提供一种RRM测量方法及设备，用以使终端设备能够灵活地对目标频点上的邻区执行放松RRM测量，从而既能够保证终端设备的通信性能又能够节省终端设备的功耗。其中，方法和设备是基于同一技术构思的，由于方法及设备解决问题的原理相似，因 此设备与方法的实施可以相互参见，重复之处不再赘述。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端设备，是一种向用户提供语音和/或数据连通性的设备。终端设备又可以称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。
例如，终端设备可以为具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
2)、网络设备，是通信系统中将终端设备接入到无线网络的设备。网络设备作为无线接入网中的节点，其例如为基站，网络设备还可以称为无线接入网(radio access network，RAN)节点(或设备)。本申请实施例中基站侧执行的方案也可以由其他网络设备执行，本申请实施例不作限制。
目前，一些基站的举例为：gNB、演进型节点B(evolved Node B，eNB)、传输接收点(transmission reception point，TRP)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)，或基带单元(base band unit，BBU)等。
另外，在一种网络结构中，所述基站可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点。这种结构将长期演进(long term evolution，LTE)系统中eNB的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
3)、参考信号，由基站通过其管理的小区发送的，用于使终端设备进行RRM测量，以实现小区重选和小区切换以及确定波束等流程。示例性的，在本申请实施例中，所述参考信号可以为同步信号块(synchronization signal block，SSB)，信道状态信息参考信号(channel state information-reference signal，CSI-RS)等。
4)、信号质量，为终端设备针对小区进行RRM测量，得到的测量结果，可以包含以下信号质量参数中的一项或多项：
信号幅值(Srxlev，后续描述中可以用S rxlev表示)，信号强度(Squal，后续描述中可以用S qual表示)、参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)、信噪比(signal to noise ratio，SNR)、信干噪比(signal to interference plus noise ratio，SINR)等。
5)、小区的测量配置信息，为管理该小区的基站通过系统消息(例如系统消息块2(system information blocks，SIB2))广播的，用于接入该小区的终端设备执行RRM测量。
其中，该测量配置信息中包含该小区所在频点的优先级(cell reselection priority)、测量门限(S search)。其中，所述测量门限中可以包括同频测量门限(Sintrasearch，后续描述中可以用S intrasearch表示)，以及异频/异系统测量门限(Snonintrasearch，后续描述中可以用 S nonintrasearch表示)。需要说明的是，当通信系统中通过一个信号质量参数表示信号质量时，以上同频测量门限和异频/异系统测量门限也对应为1个；当通信系统中通过多个信号质量参数表示时，以上门限也对应为多个。
示例性的，当通信系统通过信号幅值和信号强度表示信号质量时，所述同频测量门限包括：同频测量信号幅值门限(SintrasearchP，后续描述中可以用S intrasearchP表示)和同频测量信号强度门限(SintrasearchQ，后续描述中可以用S intrasearchQ表示)。其中，S intrasearchP用于指示同频测量的信号幅值门限，S intrasearchQ用于指示同频测量的信号强度门限。在目前的测量策略中，以该小区为服务小区的终端设备测量到该小区信号质量满足以下条件时，所述终端设备开始对在服务频点(服务小区所在频点)上的邻区执行测量：该小区的信号质量中的信号幅值(S rxlev)大于所述S intrasearchP，且该小区的信号质量中信号强度(S qual)大于所述S intrasearchQ。
同时，所述异频/异系统测量门限包括：异频测量信号幅值门限(SnonintrasearchP，后续描述中可以用S nonintrasearchP表示)和异频测量信号强度门限(SnonintrasearchQ，后续描述中可以用S nonintrasearchQ表示)。其中，S nonintrasearchP用于指示异频/异系统测量的信号幅值门限(This specifies the Srxlev threshold(in dB)for NR inter-frequency and inter-RAT measurements)，S nonintrasearchQ用于指示异频/异系统测量的信号强度门限(This specifies the Squal threshold(in dB)for NR inter-frequency and inter-RAT measurements)。在目前的测量策略中，以该小区为服务小区的终端设备测量到该小区信号质量满足以下条件时，所述终端设备对在高优先级目标频点上的邻区执行测量：该小区的信号质量中的信号幅值(S rxlev)大于所述S nonintrasearchP，且该小区的信号质量中信号强度(S qual)大于所述S nonintrasearchQ；当终端设备测量到的该小区信号质量不满足该条件时，所述终端设备对高优先级目标频点、同等优先级目标频点和低优先级目标频点上的邻区执行测量。
6)、小区测量的目标频点，为基站配置给终端设备的。所述终端设备对在该目标频点上的邻区进行测量，以根据得到的测量结果进行小区重选或切换。
根据目标频点与服务频点(即终端设备的服务小区所在频点)的关系，基站配置的目标频点可以分为两类：
同频频点：即服务频点。
异频频点：与服务频点不同的目标频点。进一步的，根据异频频点的优先级与服务频点的优先级的相对关系，可以将异频频点分为三类：高优先级目标频点，同等优先级目标频点，低优先级目标频点。其中，高优先级目标频点为优先级高于服务频点的优先级的异频频点；同等优先级目标频点为优先级与服务频点的优先级相同的异频频点；低优先级目标频点为优先级低于服务频点的优先级的异频频点。
另外，为了便于区分和描述，在本申请实施例中，将在同频频点上的邻区称为同频邻区，将在异频频点上的邻区称为异频邻区。
7)、小区测量，包括RRM测量和无线链路监测(radio link monitoring，RLM)测量。
8)、“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是，本申请中所涉及的多个，是指两个或两个以上。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述 的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
下面结合附图，对本申请实施例进行具体说明。
图1示出了本申请实施例提供的测量方法适用的一种可能的通信系统的架构。参阅图1所示，在该通信系统中包括基站和终端设备。
所述基站，通过管理的小区为所述终端设备提供无线接入有关的服务，实现无线物理层功能、资源调度和无线资源管理、服务质量(Quality of Service，QoS)管理、无线接入控制以及移动性管理(例如小区的重选和切换)功能。
其中，每个基站负责管理至少一个小区。如图所示，基站A负责管理小区a，基站B负责管理小区b，基站C负责管理小区C。
在该通信系统中，每个小区均使用相应的频点的频谱资源为终端设备提供接入服务。需要说明的是，不同小区使用的频点可能相同，也可能不相同。另外，本申请不限定每个小区使用的通信技术，且不同的小区使用的通信技术可以相同，也可以不同。示例性的，小区a-小区g均为使用4G通信技术的LTE小区；或者小区a-小区g均为使用5G通信技术的NR小区；或者其中部分小区为LTE小区，部分小区为NR小区。
所述终端设备，为通过所述基站管理的小区接入网络的设备。
所述基站和所述终端设备之间通过Uu接口连接，从而实现所述终端设备和所述基站之间的通信。
另外，图1所示的架构可以应用到多种通信场景中，例如，第五代(The 5th Generation，5G)通信系统(又称为新无线(new radio，NR)通信系统)、未来的第六代通信系统和演进的其他通信系统、长期演进(Long Term Evolution，LTE)通信系统、车到万物(vehicle to everything，V2X)、长期演进-车联网(LTE-vehicle，LTE-V)、车到车(vehicle to vehicle，V2V)、车联网、机器类通信(Machine Type Communications，MTC)、物联网(internet of things，IoT)、长期演进-机器到机器(LTE-machine to machine，LTE-M)、机器到机器(machine to machine，M2M)等通信场景中。
在图1所示的通信系统中，由于终端设备的移动性，终端设备可以从一个小区的覆盖范围内移动到另一个小区的覆盖范围内，如图中所示的终端设备从小区a移动到小区b，因此，终端设备需要不断通过小区测量，改变其驻留的小区，以保证业务的连续性。为了实现上述目标，终端设备需要通过小区重选或小区切换过程实现。
为了保证终端设备能够实现小区重选或小区切换，管理每个小区的基站通过系统消息在其管理的小区覆盖范围内广播该小区的测量配置信息，并通过系统消息或RRC消息发送该小区的目标频点配置信息。其中，所述目标频点配置信息中包含待测量的目标频点，还可以包含在每个目标频点上的待测量的邻区。这样，当终端设备在接收到其服务小区的测量配置信息和目标频点配置信息后，根据该测量配置信息，对目标频点上的邻区执行测量，并根据测量结果进行小区重选或切换。
为了使终端设备的小区重选或小区切换更灵活，管理每个小区的基站可以依据自身能够提供的服务质量等情况设置该小区所在频点的优先级。通常频点的优先级的取值范围为(0-7)，取值越大表示频点的优先级越高。
例如，在频点1上的小区1可能系统带宽较大、信号质量较优，或能够提供更高的传 输速率(例如热点小区)，管理小区1的基站可以在小区1的测量配置信息中将频点1的优先级设置为7。
又例如，在频点2上的小区，其系统带宽、信号质量和传输速率不及在频点1上的小区，那么管理小区2的基站可以在小区2的测量配置信息中将频点2的优先级设置为5。
再例如，在频点3上的小区可能系统带宽较小、信号质量较差，或传输速率较低，因此管理小区3的基站可以在小区3的测量配置信息中将频点3的优先级设置为3。
这样，终端设备在进行小区测量时，根据每个目标频点的优先级与服务频点的优先级相对关系，可以将目标频点中的异频频点分为三类：高优先级目标频点，同等优先级目标频点，低优先级目标频点。
通过以上描述可知，终端设备对低优先级目标频点和同等优先级目标频点上的邻区进行测量，是为了解决终端设备的小区覆盖问题。如图1所示，小区a为终端设备的服务小区，当终端设备移动到小区a的边缘时，发起对这类频点上邻区(小区b、小区c等)的测量。这样，当终端移动到这类频点上的邻区的覆盖范围内时，终端设备可以重选到信号质量更好的邻区上去。而终端设备对高优先级目标频点上的邻区进行测量，是希望在这类频点的邻区驻留，以便能够得到的更好的服务。
为了兼顾终端设备的小区覆盖问题和服务质量问题，终端设备对不同的优先级目标频点的邻区进行测量的触发条件也存在差异：一般情况下，当终端设备确定服务小区信号质量大于异频/异系统测量门限时，仅对在高优先级目标频点上的邻区进行测量；当终端设备确定信号质量不大于该异频/异系统测量门限时，对在高优先级目标频点、同等优先级目标频点和低优先级目标频点上的邻区进行测量。
由于终端设备执行小区测量也是终端设备的功耗来源，因此为了既可以保证终端设备的通信性能，还可以有效地节省终端设备的功耗，通信领域引出了放松测量的概念。在执行放松测量时，终端设备可以减少测量对象(例如，减少目标频点的数量、减少待测量的邻区的数量)，或者减少测量的频率(例如，增加检测时延T detect，增加测量时延T measure，或者增加评估时延T evaluate)，或者不进行小区测量。
实施例一：
为了使终端设备能够灵活地对目标频点上的邻区执行放松测量，从而既可以保证终端设备的通信性能又可以节省终端设备功耗，本申请实施例提供了一种测量方法。该方法可以适应于图1所示的通信系统中。本申请实施例以通信系统通过信号幅值和信号强度表示信号质量为例进行具体说明。
终端设备保存有放松测量门限threshold relaxmeasure。所述放松测量门限threshold relaxmeasure用于判断是否进行放松测量。所述放松测量门限threshold relaxmeasure包含：
同频放松测量门限threshold intrarelaxmeasure：同频放松测量信号幅值门限threshold intrarelaxmeasureP，和同频放松测量信号强度门限threshold intrarelaxmeasureQ；
异频放松测量门限threshold nonintrarelaxmeasure：异频放松测量信号幅值门限threshold nonintrarelaxmeasureP，和异频放松测量信号强度门限threshold nonintrarelaxmeasureQ。
其中，所述同频放松测量门限threshold intrarelaxmeasure用于判断是否对同频邻区进行放松测量。所述异频放松测量门限threshold nonintrarelaxmeasure用于判断是否对异频邻区进行放松测量。同频放松测量信号幅值门限threshold intrarelaxmeasureP为判断是否对同频邻区进行放松测 量的服务小区的信号幅值临界值；同频放松测量信号强度门限threshold intrarelaxmeasureQ为判断是否对同频邻区进行放松测量的服务小区的信号强度临界值；异频放松测量信号幅值门限threshold nonintrarelaxmeasureP为判断是否对异频邻区进行放松测量的服务小区的信号幅值临界值；异频放松测量信号强度门限threshold nonintrarelaxmeasureQ为判断是否对异频邻区进行放松测量的服务小区的信号强度临界值。
另外，所述同频放松测量门限threshold intrarelaxmeasure大于预设的门限标准起始值(后续可以用threshold Criterion S表示)，且小于服务小区的测量配置信息中的同频测量门限S intrasearch。具体的，门限标准起始值threshold Criterion S<同频放松测量信号幅值门限threshold intrarelaxmeasureP<同频测量信号幅值门限S intrasearchP；门限标准起始值threshold Criterion S<同频放松测量信号强度门限threshold intrarelaxmeasureQ<同频测量信号强度门限S intrasearchQ。
所述异频放松测量门限threshold nonintrarelaxmeasure大于预设的门限标准起始值(后续可以用threshold Criterion S表示)，且小于服务小区的测量配置信息中的异频/异系统测量门限S nonintrasearch。具体的，门限标准起始值threshold Criterion S<异频放松测量信号幅值门限threshold nonintrarelaxmeasureP<异频测量信号幅值门限S nonintrasearchP；门限标准起始值threshold Criterion S<异频放松测量信号强度门限threshold nonintrarelaxmeasureQ<异频测量信号强度门限S nonintrasearchQ。
其中，所述门限标准起始值threshold Criterion S为：测量准入门限。即终端设备只能测量到信号质量高于该门限标准起始值threshold Criterion S的信号。当信号的信号质量低于该门限标准起始值threshold Criterion S时，终端设备无法测量到该信号。
所述同频放松测量门限threshold intrarelaxmeasure满足上述条件，可以在服务小区的信号质量在同频放松测量门限threshold intrarelaxmeasure与同频测量门限S intrasearch之间的范围内时，对同频邻区执行放松测量；否则，若设置所述同频放松测量门限threshold intrarelaxmeasure低于门限标准起始值threshold Criterion S，则会导致终端设备只要测量到服务小区的信号即开始对同频邻区进行放松测量，导致终端设备在服务小区的信号质量较差的情况下无法及时切换到同频邻区中。
所述异频放松测量门限threshold nonintrarelaxmeasure满足上述条件，可以在服务小区的信号质量在异频放松测量门限threshold nonintrarelaxmeasure与异频/异系统测量门限S nonintrasearch之间的范围内时，对异频邻区执行放松测量；否则，若设置所述异频放松测量门限threshold nonintrarelaxmeasure低于门限标准起始值threshold Criterion S，则会导致终端设备只要测量到服务小区的信号即开始对异频邻区进行放松测量，导致终端设备在服务小区的信号质量较差的情况下无法及时切换到异频邻区中；而若设置所述异频放松测量门限threshold nonintrarelaxmeasure高于异频/异系统测量门限S nonintrasearch，当服务小区的信号质量超过异频/异系统测量门限S nonintrasearch的场景中，终端设备会存在对异频邻区进行放松测量还是不对非高优先级目标频点上的邻区进行测量的逻辑冲突。
在本申请实施例中，终端设备对同频邻区的放松测量触发机制如下：
方式一：当所述终端设备确定服务小区的信号质量中信号幅值S rxlev>同频放松测量信号幅值门限threshold intrarelaxmeasureP，且服务小区的信号强度S qual>同频放松测量信号强度门限threshold intrarelaxmeasureQ，所述终端设备对同频邻区进行放松测量，如图2A所示。
对应的，当所述终端设备确定服务小区的信号质量中信号幅值S rxlev≤同频放松测量信 号幅值门限threshold intrarelaxmeasureP，和/或，服务小区的信号强度S qual≤同频放松测量信号强度门限threshold intrarelaxmeasureQ，所述终端设备对同频邻区进行正常测量。
方式二：当所述终端设备确定服务小区的信号质量中信号幅值S rxlev>同频放松测量信号幅值门限threshold intrarelaxmeasureP，或服务小区的信号强度S qual>同频放松测量信号强度门限threshold intrarelaxmeasureQ，所述终端设备对同频邻区进行放松测量。
对应的，当所述终端设备确定服务小区的信号质量中信号幅值S rxlev≤同频放松测量信号幅值门限threshold intrarelaxmeasureP，且服务小区的信号强度S qual≤同频放松测量信号强度门限threshold intrarelaxmeasureQ，所述终端设备对同频邻区进行正常测量。
在一种设计中，所述终端设备可以通过降低同频邻区的测量频率和/或降低同频邻区的数量(直至低至不进行小区测量)，对同频邻区进行放松测量。
例如，所述终端设备可以使用比正常同频测量周期T intra更大的放松同频测量周期T intrarelax对同频邻区进行放松测量。可选的，T intrarelax＝T intra*A1，A1>1。其中，正常同频测量周期T intra为终端设备对同频邻区进行正常测量时使用的测量周期，正常测量例如为：不进行放松测量。
又例如，所述终端设备将同频邻区的数量从B0降到B1，B0和B1均为大于0的整数，B1<B0。可选的，B1＝B0/A2，A2>1。
在本申请实施例中，终端设备对异频邻区的放松测量触发机制如下：
方式一：当所述终端设备确定服务小区的信号质量中信号幅值S rxlev>异频放松测量信号幅值门限threshold nonintrarelaxmeasureP，且服务小区的信号强度S qual>threshold nonintrarelaxmeasureQ，所述终端设备对目标频点上的异频邻区进行放松测量，如图2B所示。

方式二：当所述终端设备确定服务小区的信号质量中信号幅值S rxlev>异频放松测量信号幅值门限threshold nonintrarelaxmeasureP，或服务小区的信号强度S qual>threshold nonintrarelaxmeasureQ，所述终端设备对目标频点上的异频邻区进行放松测量。
当所述终端设备确定服务小区的信号质量中信号幅值S rxlev≤异频放松测量信号幅值门限threshold nonintrarelaxmeasureP，且服务小区的信号强度S qual≤异频放松测量信号强度门限threshold nonintrarelaxmeasureQ，所述终端设备对所有目标频点(包含高优先级目标频点、同等优先级目标频点、低优先级目标频点)均进行正常测量。
在一种设计中，所述终端设备可以系通过降低对异频邻区的测量频率和/或降低异频频点的数量，对异频邻区进行放松测量。
例如，所述终端设备可以使用比正常异频测量周期T nonintra更大的放松异频测量周期T nonintrarelax对异频邻区进行放松测量。可选的，T nonintrarelax＝T nonintra*A3，A3>1。其中，正常异频测量周期T nonintra为终端设备对异频邻区进行正常测量时使用的测量周期。
又例如，所述终端设备将异频频点的数量从N0降到N1，N0和N1均为大于0的整数，N1<N0。可选的，N1＝N0/A4，A4>1。
还需要说明的是，在上述方式一和方式二中，所述终端设备还可以根据服务小区的信号质量与所述异频/异系统测量门限S nonintrasearch，确定是对所有种类的异频频点上的异频邻 区进行放松测量，还是仅对高优先级目标频点上的邻区进行放松测量。具体的判断机制如下：
当异频放松测量信号幅值门限threshold nonintrarelaxmeasureP<服务小区的信号质量中信号幅值S rxlev≤所述异频/异系统测量信号幅值门限S nonintrasearchP，和/或，异频放松测量信号强度门限threshold nonintrarelaxmeasureQ<服务小区的信号质量中信号强度S qual≤所述异频/异系统测量信号强度门限S nonintrasearchQ，即终端设备需要对所有类别的异频频点进行测量的情况下，所述终端设备对在所有类别的异频频点(包含高优先级目标频点、同等优先级目标频点、低优先级目标频点)上的异频邻区均执行放松测量。
当服务小区的信号质量中信号幅值S rxlev>所述异频/异系统测量信号幅值门限S nonintrasearchP，且服务小区的信号质量中信号强度S qual>所述异频/异系统测量信号强度门限S nonintrasearchQ时，即在终端设备仅需要对高优先级目标频点进行测量，且不对同等优先级目标频点和低优先级目标频点进行测量的情况下，所述终端设备仅对高优先级目标频点上的异频邻区执行放松测量。
需要说明的是，在本申请实施例中，所述放松测量门限threshold relaxmeasure是由基站配置给所述终端设备的，例如，通信系统可以设计一种新结构的RRC信令，基站可以将threshold relaxmeasure携带在该RRC信令中。又例如，所述基站可以在系统消息SIB2中新增加一个字段，并将所述放松测量门限threshold relaxmeasure携带该字段中。所述放松测量门限threshold relaxmeasure也可以是协议规定并存储在所述终端设备内的。所述放松测量门限threshold relaxmeasure还可以是基站或终端设备按照协议定义并存储在所述终端设备内的计算方法计算得到的，或基站配置给终端设备的计算方法计算得到的。所述放松测量门限threshold relaxmeasure还可以是所述终端设备在多个门限备选值中选择的，其中，所述多个门限备选值可以为协议规定并存储在所述终端设备内的，或者为基站配置给所述终端设备的。例如，终端设备可以根据以下至少一项或组合选择所述放松测量门限threshold relaxmeasure：所述终端设备的业务优先级、服务频点优先级、所述终端设备的移动性信息。
所述终端设备的业务优先级越高，所述终端设备选择的放松测量门限threshold relaxmeasure取值越大。这样，在终端设备进行关键性业务时提高放松测量门限，以使终端设备尽量不进行放松测量，从而保证终端设备的通信性能。
所述终端设备的服务频点优先级越高(服务小区数据传输速率好、网络覆盖好等)，表示服务小区能够为终端设备提供较高的服务质量，所述终端设备选择的放松测量门限threshold relaxmeasure取值越小。这样，所述终端设备尽快进入放松测量模式，从而降低终端设备的功耗。
所述终端设备的移动信息指示终端设备不处于小区覆盖边缘，和/或终端设备的移动速度较低时，表示服务小区能够终端设备提供较高的服务质量，所述终端设备选择的放松测量门限threshold relaxmeasure取值越小。这样，所述终端设备尽快进入放松测量模式，从而降低终端设备的功耗。
示例性的，所述放松测量门限threshold relaxmeasure中各参数分别符合以下公式一至公式四：

其中，上述公式中的0<k1<1，0<k2<1，0<k3<1，0<k4<1，k1至k4可以相同也可以不同。另外，上述公式中的k1-k4的取值可以为基站确定并配置给所述终端设备的，或者协议规定并存储在终端设备内的，又或者为终端设备自行确定的。
在一种设计中，所述终端设备或所述基站可以根据以下至少一项或组合确定k1-k4的取值：所述终端设备的业务优先级、服务频点优先级、所述终端设备的移动性信息。其中，所述终端设备的移动性信息可以但不限于包含所述终端设备的位置信息和移动速度等。这样，终端设备或基站可以根据当前网络状态，动态调整所述放松测量门限。
示例性的，当终端设备的业务优先级越高，终端设备或基站设置k1-k4的取值越大，这样，根据k1-k4得到的放松测量门限的取值也越大。这样，在终端设备进行关键性业务时提高放松测量门限，以使终端设备尽量不进行放松测量，从而保证终端设备的通信性能。
示例性的，当服务频点优先级越高，终端设备或基站设置k1-k4的取值越低，这样，根据k1-k4得到的放松测量门限的取值也越低。由于服务频点优先级越高，表示服务小区能够为终端设备提供较高的服务质量，终端设备小区重选或切换的需求越低。将放松测量门限threshold relaxmeasure取值设置较小，这样，所述终端设备尽快进入放松测量模式，从而降低终端设备的功耗。
示例性的，当所述终端设备的移动信息指示终端设备不处于小区覆盖边缘，和/或所述终端设备的移动速度较低时，终端设备或基站设置k1-k4的取值越低，这样，根据k1-k4得到的放松测量门限的取值也越低。所述终端设备的移动信息指示终端设备不处于小区覆盖边缘和所述终端设备的移动速度较低，均表示服务小区能够终端设备提供较高的服务质量。将放松测量门限threshold relaxmeasure取值设置较小，这样所述终端设备尽快进入放松测量模式，从而降低终端设备的功耗。

实施例二：
为了使终端设备能够灵活地对目标频点上的邻区执行放松测量，从而既可以保证终端设备的通信性能又可以节省终端设备功耗，本申请实施例提供了一种测量方法。该方法可以适应于图1所示的通信系统中。本申请实施例以通信系统通过信号幅值和信号强度表示信号质量为例进行具体说明。
终端设备保存有放松测量门限threshold relaxmeasure。其中，在本申请实施例中，所述放松测量门限threshold relaxmeasure中包含的参数以及各个参数的取值，以及所述终端设备获取所述放松测量门限threshold relaxmeasure方法等可以参考实施例一中的描述，此处不再赘述。
所述终端设备还保存有多个同频测量信号质量范围，以根据服务小区的信号质量强弱，对同频邻区进行不同放松等级的放松测量，最终实现差异化放松测量，进一步提高放松测量的灵活性。其中，每个同频测量信号质量范围对应不同的同频放松等级，同频测量信号质量范围中包含的数值越大，其对应的同频放松等级也越大，参阅图2C所示。而同频放松等级越大，终端设备对同频邻区的测量频率越低或者同频邻区的数量越小，换句话说，同频放松等级与终端设备的功耗对应，同频放松等级越大终端设备的功耗越低。
因此，当终端设备确定服务小区的信号质量大于所述放松测量门限threshold relaxmeasure中的同频放松测量门限threshold intrarelaxmeasure(具体过程可以参考实施例一种的描述)时，所述终端设备可以通过以下步骤，根据服务小区的信号质量强弱对同频邻区进行差异化放松测量：
当所述终端设备确定所述服务小区的信号质量在第一同频测量信号质量范围内时，所述终端设备按照第一放松同频测量周期T intrarelax_1，对同频频点上的B1_1个同频邻区进行测量。即所述终端设备使用同频放松等级1，对同频邻区进行放松测量。
当所述终端设备确定所述服务小区的信号质量在第二同频测量信号质量范围内时，所述终端设备按照第二放松同频测量周期T intrarelax_2，对服务频点上的B1_2个同频邻区进行测量。即所述终端设备使用同频放松等级2，对同频邻区进行放松测量。
其中，所述第二同频测量信号质量范围内的任一数值大于所述第一同频测量信号质量范围内的数值，T intrarelax_2>T intrarelax_1和/或B1_2<B1_1，B1_2和B1_1均为大于0的整数。示例性的，T intrarelax_2＝T intrarelax_1*A5，B1_2＝B1_1/A6，A5>1，A6>1。同频放松等级2高于同频放松等级1。
其中，所述多个同频测量信号质量范围是根据同频放松测量门限threshold intrarelaxmeasure和至少一个同频放松等级门限确定的。其中，第一同频放松等级对应的第一同频测量信号质量范围为(同频放松测量门限threshold intrarelaxmeasure，第一同频放松等级门限]；第二同频放松等级对应的第二同频测量信号质量范围为(第一同频放松等级门限，第二同频放松等级门限]；……第L同频放松等级对应的第L同频测量信号质量范围为(第L-1同频放松等级门限，+∞]。
在一种设计中，每个同频放松等级门限是根据同频放松测量门限threshold intrarelaxmeasure确定的。
例如，第一同频放松等级门限＝同频放松测量门限threshold intrarelaxmeasure*j，其中j>1。
具体的，第一同频放松等级信号幅值门限threshold intrarelaxlevel_1P＝同频放松测量信号幅值门限threshold intrarelaxmeasureP*j。第二同频放松等级信号幅值门限threshold intrarelaxlevel_2P＝同频放松测量信号幅值门限threshold intrarelaxmeasureP*j 2。第L-1同频放松等级信号幅值门限threshold intrarelaxlevel_L-1P＝同频放松测量信号幅值门限threshold intrarelaxmeasureP*j L-1。
第一同频放松等级信号强度门限threshold intrarelaxlevel_1Q＝同频放松测量信号强度门限threshold intrarelaxmeasureQ*j。第二同频放松等级信号强度门限threshold intrarelaxlevel_2Q＝同频放松测量信号强度门限threshold intrarelaxmeasureQ*j 2。第L-1同频放松等级信号幅值门限threshold intrarelaxlevel_L-1Q＝同频放松测量信号强度门限threshold intrarelaxmeasureQ*j L-1。
其中，j的取值可以为所述基站通过设定计算方法计算出来配置给所述终端设备的，或者为终端设备根据设定计算方法计算的。例如，所述基站或所述终端设备可以根据以下至少一项或组合计算j的取值：所述终端设备的业务优先级、服务频点优先级、所述终端设备的移动性信息。这样，终端设备或基站可以根据当前网络状态，动态调整所述放松测量门限。
例如，当所述终端设备的业务优先级越低，服务频点优先级越高，或者终端设备的移动性信息指示终端设备距离服务小区中心越近和/或终端设备的移动速度越低时，设置j值越小。这样，可以在终端设备对小区重选或切换需求较低时，尽快进入放松测量模式，从而降低终端设备的功耗。
在另一种设计中，每个同频放松等级门限为基站配置给所述终端设备的，或者协议规定并保存在所述终端设备中的。
所述终端设备还保存有多个异频测量信号质量范围，以根据服务小区的信号质量强弱，对异频邻区进行不同放松等级的放松测量，最终实现差异化放松测量，进一步提高放松测量的灵活性。其中，每个异频测量信号质量范围对应不同的异频放松等级，异频测量信号质量范围中包含的数值越大，其对应的异频放松等级也越大，参阅图2D。而异频放松等级越大，终端设备对异频邻区的测量频率越低或者异频邻区的数量越小，换句话说，异频放松等级与终端设备的功耗对应，异频放松等级越大终端设备的功耗越低。
因此，当终端设备确定服务小区的信号质量大于所述放松测量门限threshold relaxmeasure中的异频放松测量门限threshold nonintrarelaxmeasure(具体过程可以参考实施例一种的描述)时，所述终端设备可以通过以下步骤，根据服务小区的信号质量强弱对异频邻区进行差异化放松测量：
当所述终端设备确定所述服务小区的信号质量在第一异频测量信号质量范围内时，所述终端设备按照第一放松异频测量周期T nonintrarelax_1，对异频频点上的N1_1个异频邻区进行测量。即所述终端设备使用异频放松等级1，对异频邻区进行放松测量。

其中，所述第二异频测量信号质量范围内的任一数值大于所述第一异频测量信号质量范围内的数值，T nonintrarelax_2>T nonintrarelax_1和/或N1_2<N1_1，N1_2和N1_1均为大于0的整数。示例性的，T nonintrarelax_2＝T nonintrarelax_1*A7，N1_2＝N1_1/A8，A7>1，A8>1。异频放松等级2高于异频放松等级1。
其中，所述多个异频测量信号质量范围是根据异频放松测量门限threshold nonintrarelaxmeasure和至少一个异频放松等级门限确定的。其中，第一异频放松等级对应的第一异频测量信号质量范围为(异频放松测量门限threshold nonintrarelaxmeasure，第一异频放松等级门限]；第二异频放松等级对应的第二异频测量信号质量范围为(第一异频放松等级门限，第二异频放松等级门限]；……第L异频放松等级对应的第L异频测量信号质量范围为(第L-1异频放松等级门限，+∞]。
在一种设计中，每个异频放松等级门限是根据异频放松测量门限threshold intrarelaxmeasure确定的。
例如，第一异频放松等级门限＝异频放松测量门限threshold nonintrarelaxmeasure*j，其中j>1。
具体的，第一异频放松等级信号幅值门限threshold nonintrarelaxlevel_1P＝异频放松测量信号幅值门限threshold nonintrarelaxmeasureP*j。第二异频放松等级信号幅值门限threshold nonintrarelaxlevel_2P＝异频放松测量信号幅值门限threshold nonintrarelaxmeasureP j 2。第L-1异频放松等级信号幅值门限threshold nonintrarelaxlevel_L-1P＝异频放松测量信号幅值门限threshold nonintrarelaxmeasureP j L-1。
第一异频放松等级信号强度门限threshold nonintrarelaxlevel_1Q＝异频放松测量信号强度门限threshold nonintrarelaxmeasureQ*j。第二异频放松等级信号强度门限threshold nonintrarelaxlevel_2Q＝异频放松测量信号强度门限threshold nonintrarelaxmeasureQ j 2。第L-1异频放松等级信号幅值门限threshold nonintrarelaxlevel_L-1Q＝异频放松测量信号强度门限threshold nonintrarelaxmeasureQ j L-1。
其中，j的取值可以为所述基站通过设定计算方法计算出来配置给所述终端设备的，或者为终端设备根据设定计算方法计算的。例如，所述基站或所述终端设备可以根据以下至少一项或组合计算j的取值：所述终端设备的业务优先级、服务频点优先级、所述终端设备的移动性信息。j的取值规则可以参考以上计算同频放松等级信号强度门限时的取值规则，此处不再赘述。
在另一种设计中，每个异频放松等级门限为基站配置给所述终端设备的，或者协议规定并保存在所述终端设备中的。

●Relaxation of measurement/cell identification/evaluation requirements
In RAN4 three scenarios are listed,
– #1:Low mobility scenario
– #2:Not in cell-edge scenario
– #3:Low-mobility+Not in cell-edge scenario
It was agreed in the last RAN4 meeting[1]that the RRM measurement relaxation will be applied for scenario #1 and #2.
Figure PCTCN2021079362-appb-000003
Figure PCTCN2021079362-appb-000004
Regarding how to relax the measurement,the power consumption results were discussed during SI phase.
The details of simulation assumption are in annex which is captured in TS38.840.The simulation results are given in Table 1[3].Table 1 gives the power saving gain when extending measurement periodicity.
Table 1.Power saving gain when extending measurement periodicity
  DRX＝0.32 DRX＝0.64 DRX＝1.28s DRX＝2.56
N＝4 27.9％ 24.75％ 19.7％ 14.2％
N＝8 32.5％ 28.6 23.0％ 16.5％
It can be observed that extending N times of measurement interval can bring obvious power saving gain.When the DRX is larger,the gain got from 8 times extension compared with 4 times extension is not outstanding.As network may have different preference in different scenario,the flexible method is that the extension factor is configured by network.For example,network can configure different relaxation factor for different scenario.Or the relaxation factor can also consider the UE mobility degree or location etc.The relaxation factor can be within the range of{2,8}.
Proposal 1:The extension factor for relaxed measurement can be configured by network for scenario  #1 and #2.
In the last meeting,RAN2 sent an LS to RAN4[2].The agreement was duplicated as below,

RAN2 has agreed that network indicates option a or option b.For option a,it was already agreed at RAN4#93 meeting that UE is not required to meet the intra-frequency and inter-frequency neighbour cell  measurement requirements for scenario #3.So the UE behaviour is clear.
For option b when network configures the parameters of both low mobility and not-at-cell-edge criteria,UE can perform relaxation when either low mobility or not-at-cell-edge criterion is fulfilled.If both criteria are satisfied,we don’t think that UE shall stop measurement in this case.Since network indicates option b to UE,it means that network expects relaxation measurement and expects the measurement results reported by UE.Otherwise network will indicate option a to UE.So if both criteria are satisfied,UE can choose any one,it is up to UE implementation.
Proposal 2:When network configures the parameters of both low mobility and not-at-cell-edge criteria,
-if network indicates option a,UE stops intra-frequency and inter-frequency neighbour cell  measurements when both criteria are fulfilled.
-if network indicates option b,UE performs corresponding relaxed measurement according to  which criteria is met.If both criteria are satisfied,it is left to UE implementation to choose one (either low mobility or not-at cell-edge)and perform the corresponding relaxed measurements.
In NB Iot,the following relaxed monitoring measurement rules are specified in TS 36.304.The time interval since the last measurement for cell reselection is defined as 24 hours.
Figure PCTCN2021079362-appb-000006
In power saving,if both criteria are satisfied and option a is indicated by network,UE will stop intra-frequency and inter-frequency neighbour cell measurements.In this case the interval since last measurement for cell reselection shall be considered.Obviously the 24 hours is not suitable for power saving UE.This value shall consider the network deployment,propagation environment,UE mobility direction,UE speed,UE location and etc.Too long interval may impact UE mobility performance and too short value will reduce the power saving gain.Generally we think time interval for measurement relaxation(stop measurements)since last measurement for cell reselection is minutes level.
Proposal 3:Time interval for measurement relaxation(stop measurements)since last measurement for  cell reselection is minutes level.
●RRM measurement relaxation for inter-frequency layer with higher priority
RAN4 discussed the RRM measurement for inter-frequency layer with higher priority during last meeting.
Three options are captured in[1]as following.
Figure PCTCN2021079362-appb-000007
Figure PCTCN2021079362-appb-000008
In parallel,RAN2 was discussing the same issue as well[2].
Figure PCTCN2021079362-appb-000009
In current specification if S rxlev>S nonIntraSearchP and S qual>S nonIntraSearchQ then the UE shall search for inter-RAT E-UTRAN layers of higher priority at least every T higher_priority_search where T higher_priority_search＝(60*N layers)seconds.The requirements for this case is already very relaxed,so the benefit of further relaxation is negligible.
For the case where S rxlev<S nonIntraSearchP or S qual<S nonIntraSearchQ,the UE behaviour is to perform measure inter-frequency layers of higher,equal or lower priority layers.In the current specification,the measurement requirements for higher,equal or lower priority layers is the same in this case.In power saving scenario,the power saving benefit can be foreseen if the measurement of higher priority layers is relaxed(the gain is shown in table 1).In addition,the measurement result validity due to the measurement relaxation on higher priority is not a big issue.Since the power saving trigger criteria is specified for low mobility or not-at-cell edge scenario,in both cases,there is no strong command of obtaining fast measurement results.However if different priority layers(high,equal and lower)have the same requirements of measurement,this is contradictory with the motivation of introduction of different priority layers.So S rxlev≤S nonIntraSearchP or S qual≤S nonIntraSearchQ,the relaxed requirement for the frequency layer of higher priority can use different relaxed measurement requirement as those for the frequency layer of equal/lower priority.
Proposal 4:When S rxlev>S nonIntraSearchP and S qual>S nonIntraSearchQ,no relaxation of the current  measurement delay requirement is expected for inter-frequency measurement with higher priority. When S rxlev≤S nonIntraSearchP or S qual≤S nonIntraSearchQ,the relaxed requirement for the frequency layer  of higher priority can use the different relaxed measurement requirement as those for the frequency  layer of equal/lower priority.
●Reducing the frequency layer number
Paging occasion is essential and can not be missed from UE point of view.In theory,UE can perform intra-frequency measurement during the paging occasion,which means that intra-frequency measurement doesn’t introduce extra large power consumption.
For inter-frequency measurement,UE needs to wake up additionally during DRX-OFF in order to avoid the degradation on the paging reception.As we know,the measurement requirements for inter-frequency are scaling with the frequency number.It means that the normalized power is not increased when multiple inter-frequency layers are configured.
Proposal 5:Reducing the inter-frequency layers for measurement in idle mode can not bring power  saving gain.
●Impact on early measurement reporting
Early measurement reporting is introduced in CA/DC enhancement.The intention of EMR is to fasten the CA/DC setup when UE enters to connected mode.If UE is in power saving mode,the normal measurement may be impacted.There are two cases to be discussed separately.
In scenario #1 and #2,the relaxation measurement shall be performed.In our understanding,EMR is not an urgent functionality and the measurement result derived from relaxation measurement on the carriers indicated by EMR configuration can still be applied in EMR.
Proposal 6:In scenario #1 and #2,the measurement result derived from relaxation measurement can  still be applied in EMR.
In scenario #3,UE may stop the neighbour cell measurements when UE is in power saving mode.However if the UE was configured with EMR configuration in RRC release as well,UE has no information about the neighbour cell measurement results when UE is going to enter RRC connected mode.For this case UE may need to establish CA or DC due to service load.It is reasonable to perform EMR measurement.Considering the power saving,UE can perform relaxation measurement.
Proposal 7:In scenario #3,when UE is configured with EMR,UE will perform relaxation  measurements.
●RRM impact due to cross-slot scheduling power saving technique
RAN1 is discussing the cross-slot scheduling power saving during last meeting.The framework of the impact the BWP switching is basically shown in the followings(duplicated from RAN1 chairman notes).
Figure PCTCN2021079362-appb-000010
Thus in RAN4 it is no need to discuss extending the BWP switching delay.In other words,the DCI based BWP switching delay requirements in RAN4 is unchanged.
Proposal 8:The DCI based BWP switching delay requirements in RAN4 is not impacted by cross-slot  scheduling.
This contribution provides the discussion on measurement relaxation in power saving.The proposals are provided as below:
Proposal 1:The extension factor for relaxed measurement can be configured by network for scenario #1 and #2.
Proposal 2:When network configures the parameters of both low mobility and not-at-cell-edge criteria,
-if network indicates option a,UE stops intra-frequency and inter-frequency neighbour cell  measurements when both criteria are fulfilled.
-if network indicates option b,UE performs corresponding relaxed measurement according to  which criteria is met.If both criteria are satisfied,it is left to UE implementation to choose one (either low mobility or not-at cell-edge)and perform the corresponding relaxed measurements.
Proposal 3:Time interval for measurement relaxation(stop measurements)since last measurement for  cell reselection is minutes level.
Proposal 4:When S rxlev>S nonIntraSearchP and S qual>S nonIntraSearchQ,no relaxation of the current  measurement delay requirement is expected for inter-frequency measurement with higher priority. When S rxlev≤S nonIntraSearchP or S qual≤S nonIntraSearchQ,the relaxed requirement for the frequency layer  of higher priority can use the different relaxed measurement requirement as those for the frequency  layer of equal/lower priority.
Proposal 5:Reducing the inter-frequency layers for measurement in idle mode can not bring power  saving gain.
Proposal 6:In scenario #1 and #2,the measurement result derived from relaxation measurement can  still be applied in EMR.
Proposal 7:In scenario #3,when UE is configured with EMR,UE will perform relaxation  measurements.
Proposal 8:The DCI based BWP switching delay requirements in RAN4is not impacted by cross-slot  scheduling.

放松测量/小区识别/评估要求，主要有三种场景。
#1：低移动性场景
#2：非小区边缘场景
#3：低速+非小区边缘场景
RRM放松方法对场景#1和场景#2的适用性：
场景#1：
协议-RRM测量放松加长
场景二：
协议-RRM测量放松加长
测量间隔缩放因子FFS
选项1：固定值
场景#1和场景#2的FFS值相同
场景#1和场景#2的单独值有待进一步研究
选项2：网络可配值
RRM放松方法对场景#1和场景#2的适用性：讨论了如何放宽测量，在SI阶段功耗结果进行了讨论。仿真假设的细节在TS38.840的附件中。仿真结果如表1[3]所示。表1给出了 延长测量周期时的省电增益。
表1.延长测量周期的省电增益
  DRX＝0.32 DRX＝0.64 DRX＝1.28s DRX＝2.56
N＝4 27.9％ 24.75％ 19.7％ 14.2％
N＝8 32.5％ 28.6 23.0％ 16.5％
可以看出，延长N倍的测量间隔可以带来明显的节能增益。当DRX越大，8倍扩展比4倍扩展的增益不明显。由于网络在不同场景下可能有不同的偏好，因此灵活的方法是按网络配置扩展因子。例如，网络可以针对不同的场景配置不同的放松因子。或者，放松因子也可以考虑UE的移动程度或位置等。放松因子的取值范围为{2,8}。
建议1：针对场景#1和#2，可以按网络配置宽松测量扩展因子。
在上次会议上，RAN2向RAN4[2]发送了一个LS。协议复制如下：
RAN2讨论了与NR节能RRM测量相关的问题，并达成了以下协议：
1.网络侧广播相应的放松触发准则参数，开启RRM测量放松特性。
2.当网络同时配置低移动性和非边缘准则参数时。UE可以根据网络指示的以下选项之一进行测量放松：
-选项a:UE使用低移动性标准和非小区边缘标准，即：只有同时满足这两个条件，UE才能执行放松。具体的放松行为取决于RAN4的讨论和决策；
-选项b:UE使用低移动性标准或非小区边缘标准(选择可以留给UE实现)，即：当满足低移动性或非小区边缘准则时，UE可以进行放松。而详细的放松行为与网络仅配置标准的情况相同。
3.在非小区边缘标准中，当网络侧配置RSRP和RSRQ阈值时，只有当RSRP和RSRQ阈值都满足时，UE可以进行放松。
4.RAN4的FFS-我们需要的参数(例如自小区重选中的上一次测量后的测量放松时间间隔，和该时间间隔的取值范围)。
RAN2已经同意网络指示选项a或选项b。对于选项a，在RAN4#93会议上已经商定，不需要UE满足场景#3的同频和异频邻区测量要求。因此，UE的行为是明确的。
对于选项b，当网络同时配置低移动性和非小区边缘准则的参数时，UE可以在满足低移动性或非小区边缘准则时执行放松。如果两个标准都满足，我们认为在这种情况下UE不会停止测量。由于网络向UE指示选项b，这意味着网络期望放松测量并期望UE报告的测量结果。否则，网络将向UE指示选项a。因此，如果两个标准都满足，UE可以选择任意一个，这取决于UE实现。
建议2：当网络同时配置了低移动性和非边缘小区标准参数时，
-如果网络指示选项a，则当满足这两个标准时，UE停止同频和异频邻区测量。
-如果网络指示选项b，则UE根据满足哪些条件执行相应的宽松测量。如果满足这两个条件，则由UE实现选择一个(低移动性或非边缘小区)并执行相应的宽松测量。
NB-IoT中，以下宽松时延的监控测量规则在TS 36.304中定义。距离上次小区重选测量的时间间隔定义为24小时。
5.2.4.12.0宽松监控度量规则
当要求UE根据5.2.4.2或5.2.4.2a小节中的测量规则执行同频或异频测量时，在以下情况下，UE可以选择不执行同频或异频测量：
-在TSearchDeltaP期间满足5.2.4.12.1小节中的宽松监控标准，并且
-自上次执行小区重选测量以来，已经过去了不到24小时，并且
-UE在选择或重选到新小区后，至少进行了TSearchDeltaP次同频或异频测量。
在省电模式中，如果两个条件都满足，且网络指示了选项a，则UE将停止同频和异频邻区测量。在这种情况下，应该考虑从上次小区重选测量开始的间隔。很明显，24小时不适合省电终端。这个值应该考虑网络部署、传播环境、UE移动方向、UE速度、UE位置等。周期配置过长会影响UE的移动性能，周期配置过短会降低省电增益。一般来说，我们认为测量放松(停止测量)的时间间隔，因为上次测量小区重选是分钟级。
建议3：从上次小区重选测量开始，测量放松(停止测量)的时间间隔为分钟级。
l RRM测量放松优先级高的异频层RAN4讨论了异频层优先级更高的RRM测量。
"RRM测量放松高优先级异频层
选项1：当S rxlev>S nonIntraSearchP且S qual>S nonIntraSearchQ时，对于更高优先级的异频测量，不期望放宽当前测量时延要求。当S rxlev≤S nonIntraSearchP或S qual≤S nonIntraSearchQ时，对高优先级频率层的宽松测量要求与对等/低优先级频率层的宽松测量要求相同。
选项2：在高速移动场景下，高优先级载波的测量不应放松(场景#2)。
选项3：不应放松对优先度较高的承运人的衡量。
与此同时，RAN2也在讨论同样的问题。
RAN2以前已经达成的协议：
1.高优先级频点是否宽松，取决于网络配置。关于如何进行配置，有待进一步研究。RAN2正在讨论高优先级测量放松指示，并想询问RAN4关于高优先级载波放松行为：
一、对于S rxlev>S nonIntraSearchP且S qual>S nonIntraSearchQ的情况，如果满足RAN2定义的放松准则，RAN4是否设想进一步放宽比Thigher_priority_search更高优先级载波的测量？
二、对于S rxlev<S nonIntraSearchP或S qual<S nonIntraSearchQ的情况，如果满足RAN2定义的放松标准，是否有性能或系统优势只放松同等/低优先级载波的测量，而不放松高优先级载波的测量？
在目前的规范中，如果S rxlev>S nonIntraSearchP且S qual>S nonIntraSearchQ，则UE应至少在每个Thigher_priority_search中搜索具有较高优先级的异系统E-UTRAN层，其中Thigher_priority_search＝(60*Nlayers)秒后生效。对于这种情况，要求已经很宽松了，所以进一步放宽的好处可以忽略不计。
对于S rxlev<S nonIntraSearchP或S qual<S nonIntraSearchQ的情况，UE行为是测量具有较高、相同或较低优先级层的异频层。在当前规范中，对于高优先级、等优先级或低优先级的测量要求在此情况下是相同的。在节能场景下，如果放松对高优先级层的测量，可以预见节能收益(如表1所示)。此外，由于测量放宽到更高的优先级，因此测量结果的有效性不是大问题。由于节能触发标准被指定为低移动性和非小区边缘场景指定的，在这两种情况下，都没有快速获得测量结果的强大命令。然而，如果不同的优先级层(高、同等和低)具有相同的测量要求，这与引入不同优先级层的动机是矛盾的。因此，S rxlev≤S nonIntraSearchP或S qual≤S nonIntraSearchQ，高优先级频率层的放松要求可以与同等优先级/低优先级频率层的放松要求不同。
建议4：当S rxlev>S nonIntraSearchP且S qual>S nonIntraSearchQ时，对高优先级的异频测量不放宽当前测量时延要求。当S rxlev≤S nonIntraSearchP或S qual≤S nonIntraSearchQ时，对高优先级频率层宽松测量需求与等/低优先级频率层宽松测量需求不同。
减少频率层数
从UE的角度来看，寻呼时机是必不可少的，不能错过。理论上，UE可以在寻呼时刻进行同频测量，这意味着同频测量不会引入额外的大功耗。
对于异频测量，UE需要在DRX-OFF期间额外唤醒，以避免寻呼接收下降。我们知道，对异频的测量要求是随着频率数目而缩放。即当异频层数大于1层时，不抬升归一化功率。
建议5：减少空闲态测量的异频层数，无法带来节能增益。
对早期测量报告的影响
CA/DC增强引入提前上报测量报告功能。EMR的目的是在UE进入连接态时加快CA/DC的建立。如果UE处于省电模式，可能会影响正常的测量。有两种情况需要分别讨论。
在场景#1和#2中，应执行放松测量。据我们了解，EMR并不是一个迫切的功能，在EMR配置指示的载波上进行弛豫测量得到的测量结果仍然可以应用于EMR。
提案6：在场景#1和#2中，放松测量得到的测量结果仍可应用于EMR。
在场景#3中，当UE处于省电模式时，UE可以停止邻区测量。然而，如果UE在RRC释放中也配置了EMR配置，则当UE准备进入RRC连接模式时，UE没有关于邻区测量结果的信息。这种情况下，UE可能由于业务负载需要建立CA或DC。EMR测量是合理的。考虑到省电，UE可以进行放松测量。
建议7：在场景#3中，当UE配置EMR时，UE将执行放松测量。
跨时隙调度节能技术对RRM的影响
RAN1上次会议正在讨论跨时隙调度节能。BWP切换的影响框架基本如下所示。
总结："如果DCI格式1_1(或0_1)指示不同于激活的DL(或UL)BWP的目标DL(或UL)BWP，。所述最小适用调度偏移指示域(如果存在于所述DCI格式中)指示应用于所述目标BWP的最小调度偏移限制。注：规格无需变更。
因此，在RAN4中，无需讨论延长BWP切换时延。换句话说，RAN4中基于DCI的BWP切换时延要求不变。
建议8：RAN4中基于DCI的BWP切换时延要求不受跨时隙调度的影响。
本文就节能中的测量放松问题进行了探讨。提议如下：
建议1：针对场景#1和#2，可以按网络配置宽松测量扩展因子。
建议2：当网络同时配置了低移动性和非边缘小区标准参数时，-如果网络指示选项a，则当满足这两个标准时，UE停止同频和异频邻区测量。-如果网络指示选项b，则UE根据满足哪些条件执行相应的宽松测量。如果满足这两个条件，则由UE实现选择一个(低移动性或非边缘小区)并执行相应的宽松测量。
建议3：从上次小区重选测量开始，测量放松(停止测量)的时间间隔为分钟级。
建议4：当S rxlev>S nonIntraSearchP且S qual>S nonIntraSearchQ时，对高优先级的异频测量不放宽当前测量时延要求。当S rxlev≤S nonIntraSearchP或S qual≤S nonIntraSearchQ时，对高优先级频率层宽松测量需求与等/低优先级频率层宽松测量需求不同。
建议5：减少空闲态测量的异频层数，无法带来节能增益。
建议6：在场景#1和#2中，放松测量得到的测量结果仍可应用于EMR。
建议7：在场景#3中，当UE配置EMR时，UE将执行放松测量。
建议8:RAN4中基于DCI的BWP切换时延要求不受跨时隙调度的影响。
