Description

由用户设备执行的测量放松评估方法及用户设备 技术领域
本发明涉及无线通信技术领域，更具体地，本发明涉及由用户设备执行的测量放松评估方法以及相应的用户设备。
背景技术
随着5G的标准化和逐步商用，其应用场景也越来越多元化。首先，对于工业无线传感器场景，各种传感器种类繁多、用途各异。这些传感器中，一部分要求高可靠低时延或者大带宽，一部分要求超低成本和超长的电池使用寿命，而还有一部分的要求则介于前两者之间。这部分设备可以被认为是一些降低能力的NR设备(RedCap UE)。其次，随着智慧城市的规划和发展，视频监控和信息采集被普遍使用，用于这类应用的无线设备也有上面提到的降低能力的NR设备的类似特点。最后，众多的可穿戴设备，如智能手表、智能手环、健康状况监控仪等，也同样具有降低能力的NR设备的特点。对于这一类降低能力的NR设备，原有的标准并不能够很好的支撑其达到最佳的性能要求。
基于上述原因，2021年3月，在第三代合作伙伴计划(3rd Generation Partnership Project：3GPP)RAN#91e次全会上，针对版本17的降低能力NR设备的工作项目(参见非专利文献：RP-210918 Revised WID on support of reduced capability NR devices)获得批准。该工作项目将项目的适用场景确定为工业无线传感器，视频监控和可穿戴设备。该工作项目的目标之一是对降低能力的NR设备的功耗节省以及电池寿命增强的研究，包括减少下行控制信道(PDCCH)的监听，RRC非激活状态或空闲状态下的eDRX(扩展的不连续接收)，和无线资源管理(RRM)测量放松。对于降低能力的NR设备的RRM测量放松主要包含针对邻小区测量的放松，RRC空闲态、非激活态下和连接态下都可以进行RRM测量放松。对于RRC连接态，网络可以给RedCap UE配置RRM测量放松准则的相关参数，当RedCap UE满足RRM放松准则的情况发生变化后报告给网络，由网络控制是否进行RRM测量放松以及如何进行RRM测量放松。
同时，2019年12月，在第三代合作伙伴计划(3rd Generation Partnership Project：3GPP)RAN#86次全会上，针对版本17的节省功率消耗增强的工作项目(参见非专利文献：RP-193239New WID：UE Power Saving Enhancements)，并获批准。该工作项目的最新版本参见非专利文献：RP-200938 Revised WID_UE Power Saving Enhancements for NR_Change。该工作项目主要研究RRC空闲态和RRC非激活态下终端如何节省功率。该工作项目的目标之一是研究和评估低移动性场景下放松终端的无线链路监测和放松终端的波束失败检测。无线链路监测和波束失败检测都是在RRC连接态进行的。对于低移动性终端，无线链路质量一般相对稳定。在这种情况下，经过一定的准则判断后，终端可以放松无线链路监测，比如减少采样次数、加长监测周期等。同样，经过一定的准则判断后，也可以放松波束失败检测，从而达到节省功耗的目的。用于判断的准则包括低速移动准则和好小区准则，这两个准则都是网络可选地配置给终端的。
由于RedCap UE需要节省功耗，因此如上所述的版本17中的节省功率增强的工作项目中的研究结果也同样适用于RedCap UE。
本发明讨论在RRC连接态下，UE如何评估RRM放松准则和上报满足RRM放松准则的情况给网络，以及如何评估RLM/BFD放松准则和上报满足RLM/BFD放松准则的情况给网络。
发明内容
本发明的目的在于，提供能够准确地进行测量放松评估的方法和应用该方法用户设备。
根据本发明的一个方面，提供一种由用户设备执行的测量放松评估方法，包括：对所述用户设备所处于的小区执行给定类型的测量，获得当前测量值；以及基于针对与所述给定类型的测量相应的测量放松的参考测量值、所述当前测量值以及给定阈值，评估是否满足与所述测量放松对应的测量放松准则，其中，若在获得所述当前测量值时所述小区的测量配置发生了改变，则针对所述测量放松的所述参考测量值被更新成所述当前测量值，并且是否满足所述测量放松准则的评估基于更新后的参考测量值进行。
根据本发明的另一方面，还提供一种用户设备，包括：处理器；以及存储器，存储有指令，其中，所述指令在由所述处理器运行时执行如上所述的方法。
根据本发明的方案，能够准确地对是否满足放松测量准则进行评估，从而能够使用户设备正确地执行或不执行测量放松。另一方面，本发明还能够正确地向基站报告满足或不满足放松测量准则的状态，并且节省功耗。

连接态RRM测量
NR的测量模型图1所示，在图1中的各个标号的含义如下所示。
-A：物理层内部的单个波束的测量样本。
-层1滤波：物理层内部基于单个波束测量样本所做的层1(L1)的过滤过程。

-C：测量结果，作为上报准则评估的输入。
-对上报准则进行评估：根据测量报告的配置参数，评估是否需要触发测量报告上报。该评估可以是基于对不同测量的比较，例如上图中的C和C1表示不同的测量结果。

-波束选择上报：从E点获得的K个波束的测量结果中选取X个波束的测量结果。
-F：在空口上报包含波束测量结果的测量报告给基站
在RRC连接态下，基站可以给UE发送测量配置，其中包括测量对象配置，测量报告配置，测量标识配置，质量配置，测量间隔(gap)配置等。在测量报告配置中可以配置触发测量报告的类型，包括周期测量报告和事件测量报告。对于事件测量报告，基站配置测量报告的触发准则也就是各种RSRP/RSRQ以及时间等门限值，当满足准则时UE可以发送测量报告给基站。发送事件触发的测量报告后，在未得到基站响应前，UE将对该事件的测量报告周期地上报给基站。对于服务小区(serving cell)，连接态RRM测量可以被配置为基于SSB测量，此时测量的SSB是CD-SSB。对于服务 小区，连接态RRM测量也可以被配置为基于CSI-RS测量。服务小区包括PCell，PSCell和SCell。
在版本17中，对于RRC连接态，基站可以为UE配置用于连接态RRM测量放松准则(relaxation criterion)。UE对PCell进行RRM测量后判断测量值是否满足该准则，如果满足该准则的状态发生变化，即由不满足准则变为满足准则或由满足准则变为不满足准则，则UE可以发送UE辅助信息(UEAssistanceInformation)消息上报给基站，其中携带该UE是否满足连接态RRM测量放松准则的指示信息。基站收到该信息后，根据其中的指示信息，可以通过信令指示UE启动或者停止连接态RRM测量放松，或者调整连接态RRM放松的相关参数。
连接态RRM测量放松准则可以包含静止准则，即通过PCell的当前测量值与一个参考测量值进行比较，如果参考测量值减去当前测量值小于一个门限值，则UE满足RRM测量放松准则。如果当前测量值大于参考测量值，或者已经在一段时间内都不满足RRM测量放松准则，则将参考测量值设置为当前测量值。如果UE被配置需要上报RRM测量放松准则满足指示给基站，UE可以执行如下的判断和操作：
1>如果一段时间内都满足RRM测量放松准则：
2>如果自从被基站配置需要上报RRM测量放松准则满足指示给基站起UE还没有发送过指示表明满足放松准则给基站，或者上次发送指示给基站是表明不满足放松准则，则UE发送UEAssistanceInformation消息给基站，携带指示信息表明UE满足放松准则；
1>否则，
2>如果上次发送指示给基站是表明满足放松准则，则发送UEAssistanceInformation消息给基站，携带指示信息表明UE不满足放松准则。
同时，在版本17中，引入NCD-SSB。RRC连接态UE根据网络的配置或指示基于CD-SSB或者基于NCD-SSB对服务小区进行RRM测量。例如UE的当前激活下行BWP含有CD-SSB，当UE的激活下行BWP发生切换时，有可能新的激活下行BWP中并不含有CD-SSB而是含有NCD-SSB，则UE就可能从基于CD-SSB对服务小区进行测量改为基于NCD-SSB对服 务小区进行测量。
RLM/BFD
RLM指的是UE根据网络配置的参考信号监测下行无线链路质量，目的是为了检测到SpCell(即PCell，PSCell)或者服务小区serving Cell的下行无线链路质量的情况。配置的用于RLM流程的参考信号可以是SSB和/或CSI-RS。UE在激活的下行BWP上执行RLM流程。
BFD是UE根据网络配置的参考信号检测波束，目的是为了检测到波束失败的情况。BFD流程可以针对每个Serving Cell，包括SpCell和SCell。配置的用于BFD流程的参考信号可以是SSB和/或CSI-RS。UE在激活的下行BWP上执行BFD流程。
对于低移动性终端，无线链路质量一般相对稳定。在这种情况下，经过一定的准则判断后，终端可以放松RLM/BFD，比如减少采样次数、加长监测评估周期、加长上报指示周期等。在RRC连接态，RLM/BFD放松可以是基站通过系统消息或者RRC专有信令配置放松准则配置参数，放松准则可以包括低速移动准则(low mobility)和好服务小区质量准则(good serving cell quality)。配置参数可以包括准则的开关、准则的门限和判决时间参数等。UE通过对SpCell或serving cell的测量结果和RLM/BFD放松准则中的门限值进行比较、评估，判断自己的移动性和服务小区质量，如果满足放松准则，则UE可以采用放松的RLM/BFD。
通过本发明，在RRC连接态下，UE可以准确评估RRM放松准则和正确上报满足RRM放松准则的情况给网络，以及准确评估RLM/BFD放松准则和正确上报满足RLM/BFD放松准则的情况给网络，从而既节约UE的功耗又不影响UE的移动性能。
以下，首先参考图2来说明本发明的概要。图2是根据本发明的实施方式的测量放松评估方法的流程图。
如图2所示，在201，对用户设备所处于的小区执行给定类型的测量，获得当前测量值。给定类型的测量例如包括RRM测量、BFD测量、RLM测量等。下文提及的测量放松可以与给定类型的测量对应，例如RRM测量对应于RRM测量放松，BFD测量对应于BFD测量放松，RLM测量对应于 RLM测量放松。用户设备所处于的小区例如可以是SpCell或Pcell。
然后，若得到了当前测量值，则在203，确定在获得当前测量值时小区的测量配置是否发生了改变。
用户设备可以基于SSB来执行测量，在该情况下，测量配置可以是SSB测量配置，例如SSB频率、SSB类型等。SSB类型例如包括前述的CD-SSB和NCD-SSB。此时，可以在满足以下中的至少一种条件的情况下，确定为所述小区的测量配置发生了改变：用于对小区进行测量的SSB的类型发生了改变；当前测量值所基于的SSB的类型与当前的参考测量值所基于的SSB的类型不同；用于对小区进行测量的SSB的频率发生了改变；当前测量值所基于的SSB的频率与当前的参考测量值所基于的SSB的频率不同。
所谓当前测量值所基于的SSB的频率或SSB类型，是指获得当测量值所使用的SSB的频率或类型。所谓当前的参考测量值所基于的SSB的频率，是指当前的参考测量值被设定时用于测量的SSB频率或类型，或者若当前的参考测量值被进行了更新，也可以是指过去被更新成参考测量值的实际测量值(即在过去某时刻时的当前测量值)被获得时所使用的SSB的频率或类型。
用户设备也可以基于CSI-RS来执行测量，在该情况下，测量配置为CSI-RS配置。CSI-RS配置可以包含子载波空间(subcarrier spacing)、CP类型、CSI-RS的中心频率等中的至少一者。此时，可以在满足以下中的至少一种条件的情况下，确定为所述用户设备所处于的小区的测量配置发生了改变：用于测量小区的CSI-RS的配置发生了改变；当前测量值所基于的CSI-RS配置与当前的所述参考测量值对应的CSI-RS的配置不同。所谓CSI-RS配置发生了改变，即可以是CSI-RS配置中的一个或多个参数的值本身的改变，也可以指CSI-RS配置中的一个或多个参数的值所在的数值范围的改变。
若在203中确定出测量配置发生了改变，则在205，将参考测量值更新成所获得的当前测量值。此外，也可以在获取到当前测量值时测量配置发生了改变之后经过了第一预定时间的情况下，将针对测量放松的参考测量值更新为当前测量值。由此，能够避免因测量配置的频繁变化而频繁变更参考测量值，从而保证评估的稳定性。
在更新参考测量值时，可以将参考测量值更新成当前测量值与给定偏 移值相加后所得到的值。若给定类型的测量基于SSB来执行，则给定偏移值可以基于SSB的频率范围来确定。若给定类型的测量基于CSI-RS来执行，则给定偏移值可以基于CSI-RS配置中的一个或多个参数的取值范围来确定。例如，可以配置偏移值表，在该偏移值表示，不同取值的偏移值与SSB的频率范围或CSI-RS的一个或多个参数的取值范围建立了对应。给定偏移值也可以基于当前测量值所基于的SSB频率与当前的参考测量值所基于的SSB的频率之间的差值来确定。同样，给定偏移值也可以基于当前测量值所基于的CSI-RS的一个或多个参数的取值，与当前的参考测量值所基于的对应参数的取值之间的差值来确定。
然后在209，基于更新后的参考测量值、当前测量值以及给定阈值，评估是否满足测量放松准则，该测量放松准则对应于与上述给定类型的测量相应的测量放松。
若测量配置未发生改变，则在207，不更新参考测量值，进而在209，基于当前的参考测量值来评估是否满足测量放松准则。
在获取到评估结果之后，用户设备可以基于评估结果来决定是否执行测量放松，或是否从正在执行的测量放松中退出而执行正常的测量。
在获取到评估结果之后，用户设备还可以确定是否需要向基站报告测量放松准则满足状态。测量放松准则满足状态包括满足放松准则的状态和不满足放松准则的状态。例如，若用户设备被基站配置了需要向基站报告，则可以确定为需要向基站报告。再例如，用户设备可以自行决定按照给定周期或在给定条件下向基站报告。
在确定需要向基站报告测量放松准则满足状态时，用户设备可以基于评估结果来向基站报告测量放松准则满足状态指示。
用户设备可以在根据所述评估结果判定出测量放松准则满足状态发生了改变时，向基站报告改变后的放松准则满足状态，否则可以不报告。由此减少节省报告次数。
此外，用户设备还可以在第二给定时间内获得的评估结果均表示满足放松测量准则，并且在第二给定时间内所述测量配置未发生改变的情况下，向基站报告放松测量准则满足指示。
此外，作为另一示例，用户设备可以在第二给定时间段内测量配置发生了改变，并且上一次向基站报告了表示满足测量放松准则的消息时，向 基站报告表示不满足所述放松测量指示的消息。即，若在第二给定时间段内测量配置发生了改变，并且上一次给基站报告时被评估为满足测量放松准则，则为了避免不恰当地执行测量放松而有损用户设备的移动性，用户设备可以确定已变为不满足测量放松准则的状态，并向基站进行报告。在这种情况下，如果用户设备正在执行测量放松，则可以退出测量放松而回到正常的测量。
另外，在一个示例中，用户设备可以被配置有包括用于执行给定类型的测量的测量参数集(例如可以通过后述的MeasObjectNR来由基站配置)，在测量参数集中配置了与基于SSB来执行测量相关的配置信息时，测量参数集中不存在与CSI-RS相关的配置。
以下，举出具体的实施例来对本发明进行更详细的说明。

可选地，在405中，基于评估结果向基站发送报告。
可选地，在步骤405中，如果UE被配置需要上报RRM测量放松准则满足指示给基站，如果UE在T2时间段内都满足RRM测量放松准则，并且在T2期间用于测量PCell的CSI-RS的配置没有发生改变，才进一步判断是否需要发送UEAssistanceInformation消息给基站，携带指示信息表明UE满足放松准则。
可选地，步骤405，还可以是另一种实现方式，即如果UE被配置需要上报RRM测量放松准则满足指示给基站，如果UE在T2期间用于测量PCell的CSI-RS的配置发生了改变，如果上次发送指示给基站是表明满足放松准则，则发送UEAssistanceInformation消息给基站，携带指示信息表明UE不满足放松准则。
可选地，步骤405，还可以是另一种实现方式：如果UE未被配置需要上报RRM测量放松准则满足指示给基站(该判断为可选操作，也可以不判断)，如果UE在T2期间用于测量PCell的CSI-RS的配置发生了改变，并且如果目前UE正处于RRM测量放松，则停止RRM测量放松，和/或恢复正常的RRM测量。
其中，可选地，T2可以指PCell的测量值连续满足放松测量准则的时 间段(time period)T2可以是预配置，或者网络通过系统消息或者RRC专有信令配置。

实施例3
基于实施例1和实施例2，在本实施例中，可选地，UE基于SSB或者CSI-RS进行RRM放松测量评估由网络进行配置。配置方式可以通过系统消息，或者RRC专有信令，或者MAC CE。当UE进行RRM测量放松评估时，先根据网络配置确定采用基于SSB得到的PCell测量结果，还是采用基于CSI-RS得到的PCell测量结果。即，如果网络配置UE基于SSB进行RRM放松测量评估，则UE采用基于SSB得到的PCell测量结果进行评估；如果网络配置UE基于CSI-RS进行RRM放松测量评估，则UE采用基于CSI-RS得到的PCell测量结果进行评估。
该实施例中“RRM测量放松”可以替换为“RLM/BFD测量放松”，即所述流程也同样适用于RLM/BFD测量放松。该实施例中所提到的“PCell”也可以替换为“SpCell”，即对PCell的所述流程也同样适用于SpCell。
