一种RRM测量方法及设备
相关申请的交叉引用
本申请要求在2020年03月31日提交中国专利局、申请号为202010247300.5、申请名称为“一种RRM测量方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种RRM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，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)和小区切换(handover)，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。
其中，在终端设备处于无线资源控制(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)，终端设备通过小区重选过程切换其驻留的小区。
为了保证终端设备能够实现小区重选，基站通常会在系统消息中携带重选配置信息，其中，所述重选配置信息可以但不限于包括以下重选配置参数：触发邻区测量的服务小区信号质量门限、邻区重选的目标频点(可以包括异频/异系统的频点)，向邻区重选的邻区信号质量门限，每个目标频点上的邻区列表，每个目标频点的优先级等信息。上述为在所述基站范围内的终端设备公共的重选配置信息，所述基站还可以向指定终端设备发送供其专用的重选配置信息，此时该重选配置信息中可以包含以上重选配置参数中的至少一项，以覆盖系统消息中配置的相应的重选配置参数。终端设备在接收到上述重选配置信息之后，根据其中的重选配置参数，执行RRM测量和小区重选。
其中，在终端设备执行RRM测量和小区重选过程中，根据基站通过以上方式为终端设备配置的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，终端设备可以将每个目标频点分为以下三类中的一类：
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。
我们知道目前处于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。在执行放松RRM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、减少邻区的数量)，或者减少RRM测量的次数(例如，增加RRM测量的周期)。
目前，在R16协议上规定，当满足预设条件时，终端设备可以进行放松RRM测量。然而我们知道，终端设备针对高优先级目标频点上的邻区执行放松RRM测量，会导致终端设备长期不能重选到该邻区上，这就影响了终端设备的通信性能。

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实现对高优先级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。

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RRM测量使用的一种可能的通信系统的架构。参阅图2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202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、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RRM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，处于RRC空闲态和RRC非激活态的终端设备需要通过小区重选过程实现。
为了保证终端设备能够实现小区重选，基站通过系统消息在管理的小区内广播公共的重选配置信息。另外当终端设备接入基站后，基站还可以根据实际需求，通过RRC信令向该终端设备发送专用的重选配置信息。所述终端设备可以根据来自基站的重选配置信息，确定以下重选配置参数，并基于这些确定的重选配置参数，进行RRM测量和小区重选：
触发邻区测量的服务小区信号质量门限Td m_ser、邻区重选的目标频点，向邻区重选的邻区信号质量门限Td x，每个目标频点上的邻区列表，每个目标频点的优先级。
为了使终端设备的小区重选更灵活，基站可以针对不同的目标频点，设置不同的优先级。例如，相对于终端设备的服务小区，在频点1上的小区可能系统带宽较大、信号质量较优，或能够提供更高的传输速率，例如热点小区。因此，为了提高终端设备的服务质量，基站在将该频点1作RRM测量和小区重选的目标频点时，可以设置该频点1的优先级高于服务频点(服务小区所在的频点)的优先级。而在频点2上的小区，其系统带宽、信号质量和传输速率可能与服务小区的类似，因此基站在将这些频点2作为目标频点时，可以设置频点2的优先级与服务频点相同。另外，相对于服务小区，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，因此基站在将这些频点3作为目标频点时，可以设置频点3的优先级低于服务频点的优先级。
这样，终端设备在进行RRM测量之前，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，可以将每个目标频点分为三类中的一类：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。并且，终端设备针对不同类的目标频点的小区RRM测量触发条件不同，相应的针对不同类目标频点的小区重选规则也不同。
下面先对不同类目标频点的小区RRM测量触发条件进行说明。
对于低优先级目标频点或同等优先级目标频点，当终端设备确定服务小区的信号质量低于触发邻区测量的服务小区信号质量门限Td m_s时，触发对这类目标频点上邻区进行RRM测量。
对于高优先级目标频点，无论服务小区的信号质量如何，所述终端设备会持续发起对这类目标频点上的邻区的RRM测量。例如图2所示，其中当前服务小区为cell1，频点为f1，频点f2和f3的优先级高于f1，cell2和cell3分别为频点f2和f3上的小区。cell2和cell1有类似的覆盖范围，而cell3覆盖范围小，但也在cell1的覆盖范围内。例如：
cell1是LTE小区，cell2是NR小区，基站更希望为用户提供NR服务，因此将f2的频点优先级设置较高，希望在cell1上驻留的用户能尽快重选到cell2上；
Cell3可能是基站布置的热点小区，覆盖范围较小，但是小区带宽大，能提供更高的用户速率，基站将f2的频点优先级设置较高，希望在cell3的覆盖范围内终端能尽快重选到cell3上。
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RRM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RRM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。而基站设置高优先级目标频点，是希望终端设备在这类频点的邻区驻留，以便邻区为终端设备提供更好的服务，同样，终端设备持续对高优先级的目标频点上的邻区进行RRM测量，也是为了尽量提高在这类频点上的小区驻留的概率和时间。
下面对不同类目标频点的小区重选规则进行说明。
对于低优先级目标频点上的邻区，当一段连续的时间内服务小区信号质量持续低于一定门限，且该邻区的信号质量持续高于一定门限时，所述终端设备向该低优先级目标频点上的该邻区重选。
对于同等优先级目标频点上的邻区，根据信号质量对其和服务小区排序，所述终端设备向在一段时间内排名持续高于服务小区的同等优先级目标频点上的该邻区重选。
对于高优先级目标频点上的邻区，当一段连续的时间内该邻区的信号质量高于一定门限时，所述终端设备向该高优先级目标频点上的该邻区重选。
对于每一类优先级目标频点，协议分别规定了RRM测量和小区重选的时延指标，主要有以下3种时延指标：
检测时延T detect：表示当所述终端设备在当前环境中检测到该目标频点上的一个新的邻区时，终端设备需要在该检测时延内完成该邻区是否满足重选条件的评估。
测量时延T measure：对于已检测到的在该目标频点上的邻区，终端设备需要在每隔一个测量时延进行一次RRM测量。
评估时延T evaluate：对于已检测到的在该目标频点上的邻区，终端设备需要每次对该邻区进行RRM测量后的该评估周期内评估出该邻区是否满足重选条件。
因此，处于RRC空闲态和RRC非激活态的终端设备在满足小区RRM测量触发条件邻时，终端设备至少需要每隔一个检测时延T detect在对应的目标频点上进行小区检测；对检测到的邻区，至少每隔一个测量时延T measure进行一次测量，并在每次测量完成后，在一个评估时延T evaluate内评估该邻区是否满足对应的重选条件。其中，上述时延指标也可以携带在重选配置信息中由基站发送给终端设备，或者为协议规定的。
通过以上描述可知，为了降低终端设备的功耗，终端设备可以通过进入RRC空闲态和RRC非激活态实现。然而终端设备在该状态下进行RRM测量和小区重选，是其功耗的主要来源。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RRM测量的概念。在执行放松RRM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RRM测量的次数(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)。
目前，R16协议中规定了当终端设备满足以下情况下，针对所有目标频点的邻区实现放松RRM测量：
A、在设定时长1内服务小区的信号质量变化不超过设定门限1。即当所述终端设备静止或低速移动时，服务小区和邻区的信号质量均比较稳定，将长时间保持在一定范围内，因此终端设备可以对所有目标频点的邻区执行放松RRM测量。
B、服务小区的信号质量高于设定门限2。即当所述终端设备不在小区边缘时，服务小区的信号质量较高，能够为终端设备提供稳定且较好的服务，因此，终端设备不需要重选到邻区上，可以对所有目标频点上的邻区执行放松RRM测量。
显然，上述传统的执行放松RRM测量的方法，可以保障终端设备的小区覆盖。然而，通过以上对高优先级目标频点的描述可知，高优先级目标频点的设置是为了终端设备提供更好的服务，例如在图2所示的场景中，若基站设置频点f2和f3的优先级较高，希望基站在小区2或小区3上驻留的以提供更优质的服务，然而，当终端设备一直处于服务小区(小区1)的覆盖范围内(不在小区1的边缘)，那么所述终端设备会按照上述放松RRM测量的方法，对所有频点上的邻区(包括小区2和小区3)执行放松RRM测量，这会导致终端设备长期不能重选到小区2和小区3上，最终影响了终端设备的通信性能。
为了使终端设备能够灵活地实现对高优先级目标频点上的邻区执行放松RRM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RRM测量方法。该方法可以适应于图1所示的通信系统中，下面参阅图3，对本申请实施例提供的方法进行详细说明。
S301：终端设备接收基站发送的重选配置信息，并按照传统的RRM测量方法，根据所述重选配置信息中的重选配置参数，对所有目标频点上的邻区和服务小区进行RRM测量。
其中，所述重选配置参数中包含至少一个目标频点，每个目标频点上的邻区列表，每个目标频点的优先级等信息。所述重选配置参数中还可以包括非放松RRM测量时每个目标频点对应的检测时延、测量时延，和评估时延，以及还可以包括放松RRM测量时每个目标频点对应的检测时延、测量时延和评估时延。
所述终端设备在对所有目标频点上的邻区进行RRM测量之前，首先对每个目标频点进行分类，确定高优先级目标频点、同等优先级目标频点和低优先级目标频点，然后针对不同类的目标频点，按照不同类目标频点对应的小区RRM测量触发条件，触发启动对该类目标频点上的邻区的RRM测量，得到该类目标频点上的邻区的信号质量。
S302：终端设备在确定满足以下至少一项设定条件时，对高优先级目标频点上的第一邻区执行放松RRM测量。
其中，所述终端设备对所述第一邻区执行放松RRM测量，包括：
所述终端设备根据以下至少一项或组合时延指标，对所述第一邻区执行放松RRM测量：
第一检测时延T detect，relax_high、第一测量时延T measure，relax_high、第一评估时延T evaluate，relax_high；
其中，其中，所述T detect，relax_high>非放松RRM测量时所述高优先级目标频点的检测时延T detect，high，所述T measure，relax_high>非放松RRM测量时所述高优先级目标频点的测量时延T measure，high，所述T evaluate，relax_high>非放松RRM测量时所述高优先级目标频点的评估时延T evaluate，high。
通过该步骤，所述终端设备可以降低对所述第一邻区的RRM测量频率，从而实现对所述第一邻区的放松RRM测量，节省所述终端设备的功耗。
需要说明的是，所述T detect，relax_high、所述T measure，relax_high和所述T evaluate，relax_high的取值可以为协议规定的，或者由基站通过重选配置信息或RRC消息发送给所述终端设备的。
示例性的，以上用于放松RRM测量的三个时延指标中的任一项可以为预设的时间长度。例如，所述T measure，relax_high可以设置为5分钟或6分钟等具体数值。
示例性的，以上用于放松RRM测量的三个时延指标中的任一项可以为其对应的非放松RRM测量时的时延指标的整数倍。例如，所述T detect，relax_high可以为所述T detect，high的整数倍；所述 measure，relax_high可以为所述T measure，high的整数倍；所述T evaluate，relax_high可以为所述T evaluate，high的整数倍。
下面对所述设定条件进行具体说明，可选的，所述条件可以但不限于为以下几项：
条件1：服务小区的信号质量在第一设定时长T speed_ser内的变化量小于第一门限Td speed_ser。其中，在该条件下，所述第一邻区为所述高优先级目标频点上任一邻区或所有邻区。
当满足条件1时，表明终端设备处于静止状态或移动速度较低，服务小区的信号质量较稳定，同理，所述终端设备的邻区的信号质量也较稳定，因此终端设备发生小区重选的概率较低，因此可以对高优先级目标频点上的邻区进行放松RRM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。
需要说明的是，在满足条件1的场景中，所述终端设备也可以对同等优先级目标频点和低优先级目标频点上的第二邻区执行放松RRM测量。其中，所述终端设备对所述第二邻区执行放松RRM测量可以按照传统的方式实现，例如降低同等优先级目标频点和低优先级目标频点的数量，减少第二邻区的数量，或者降低对第二邻区的RRM测量频率。
需要说明的是，在本申请实施例中，所述终端设备对所述第一邻区进行放松RRM测量的方式与对所述第二邻区进行放松RRM测量的具体实现方式不同。
示例性的，所述终端设备可以根据以下至少一项或组合时延指标，对所述第二邻区执行放松RRM测量：
第二检测时延T detect，relax、第二测量时延T measure，relax、第二评估时延T evaluate，relax；其中，所述T detect，relax_high小于或等于所述T detect，relax，所述T measure，relax_high小于或等于所述T measure， relax，所述T evaluate，relax_high小于或等于所述T evaluate，relax。
通过以上描述可知，虽然所述终端设备对第一邻区和第二邻区均执行放松RRM测量，但是所述终端设备对所述第一邻区进行测量的频率高于对第二邻区进行测量的频率。这样，可以提高所述终端设备重选到第一邻区的概率，从而可以保证终端设备的通信性能。
条件2：所述终端设备测量到的所述第一邻区的信号质量小于第二门限Td relax_high_c1；其中，所述Td relax_high_c1<向所述第一邻区重选的信号质量门限Td x_high_c1。
当满足条件2时，表明所述第一邻区的信号质量较差，此时终端设备可能处于所述第一邻区的边缘或覆盖范围之外，因此，所述终端设备几乎不可能重选到所述第一邻区，因此所述终端设备可以直接对该第一邻区进行放松RRM测量，从而可以节省终端设备功耗。
条件3：所述终端设备测量到的所述第一邻区的信号质量在第二设定时长T speed_high_c1内的变化量小于第三门限Td speed_high_c1。可选的，所述T speed_high_c1可以与T speed_ser取值相同，所述Td speed_high_c1可以与Td speed_ser取值相同。
与条件1对应的场景类似的，当满足条件3时，表明终端设备处于静止状态或移动速度较低，此时，服务小区的信号质量和邻区的信号质量均比较稳定，因此终端设备发生小区重选的概率较低。因此，因此可以对高优先级目标频点上的邻区进行放松RRM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。另外，所述终端设备可以 直接根据所述第一邻区的信号质量的变化判断是否应该对所述第一邻区执行放松RRM测量，可以使判断结果更准确。
条件4：所述终端设备测量到的所述高优先级目标频点上的每个邻区的信号质量小于第四门限Td relax_high_ca。其中，在该条件下，所述第一邻区为所述高优先级目标频点上任一邻区或所有邻区。可选的，所述Td relax_high_ca可以与条件2中的第二门限Td relax_high_c1取值相同。
与条件2类似的，表明所述高优先级目标频点上的所有邻区的信号质量较差，因此，所述终端设备几乎不可能重选到在该高优先级目标频点上的邻区，因此所述终端设备可以直接对该第一邻区进行放松RRM测量，从而可以节省终端设备功耗。
在一种方式中，在该条件4下，所述终端设备可以根据第一检测时延T detect，relax_high，对所述第一邻区执行放松RRM测量。所述终端设备使用的其他时延指标可以为针对放松RRM测量时设置的第一测量时延T measure，relax_high、第一评估时延T evaluate，relax_high，或者为针对非放松RRM测量时设置的T measure，high、T evaluate，high。

具体过程可以参考图3所示的实施例中的S301中的描述，此处不再赘述。
S402a：所述终端设备确定服务小区的信号质量在目标邻区对应的信号质量范围内时，对所述目标邻区执行放松RRM测量。
需要说明的是，本申请实施例中所述终端设备可以针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中的任一类目标频点上的任一邻区执行上述步骤，或者针对每个目标频点上的每个邻区执行上述步骤，或者针对部分目标频点上的每个邻区执行上述步骤，或者针对任一目标频点上的部分邻区执行上述步骤，本申请对此不作限定。
其中，所述终端设备对该目标邻区执行放松RRM测量，与图3所示的实施例中S302中终端设备对第一邻区执行放松RRM测量的方法相同，即通过增加所述目标邻区的检测时延、测量时延或评估时延，进而降低所述终端设备对该目标邻区的测量频率。所述终端设备可以具体通过以下步骤实现对所述目标邻区的放松RRM测量：

示例性的，以上用于放松RRM测量的三个时延指标中的任一项可以为预设的时间长度。例如所述T measure，relax_y可以设置为7分钟或8分钟等具体数值。
示例性的，以上用于放松RRM测量的三个时延指标中的任一项可以其对应的非放松RRM测量时的时延指标的整数倍。例如，所述T detect，relax_y为所述T detect，y的整数倍；所述T measure，relax_y为所述T measure，y的整数倍；所述T evaluate，relax_y为所述T evaluate，y的整数倍。
其中，以上用于放松RRM测量的三个指标的取值可以为协议规定的，或者由基站通过重选配置信息或RRC消息发送给所述终端设备的。
在一种实施方式中，所述终端设备可以通过以下方式，确定所述目标邻区对应的信号质量范围：
所述终端设备从基站接收所述目标邻区的放松RRM测量配置参数；
所述终端设备根据所述目标邻区的放松RRM测量配置参数，确定所述目标邻区对应的信号质量范围。
可选的，所述目标邻区的放松RRM测量配置参数中包含高门限Td relax，tall_ser，和/或，低门限Td relax，short_ser；其中，当所述目标邻区的放松RRM测量配置参数中包含所述Td relax， tall_ser时，所述目标邻区对应的信号质量范围包含：大于所述Td relax，tall_ser；当所述目标邻区的放松RRM测量配置参数中包含所述Td relax，short_ser时，所述目标邻区对应的信号质量范围包含：小于所述Td relax，short_ser。
需要说明的是，所述Td relax，tall_ser可以大于触发邻区测量的服务小区信号质量门限Td m_ser。
示例性的，所述目标邻区的放松RRM测量配置参数可以携带在重选配置信息或RRC消息中由基站发送给所述终端设备。
可选的，所述目标邻区的放松RRM测量配置参数可以为所述基站根据所述目标邻区和所述服务小区的覆盖范围，或者所述基站根据该基站的位置与管理所述目标邻区的基站的位置确定的。换句话说，当终端设备测量到服务小区的信号质量该目标邻区的信号质量范围内时，表示该终端设备的位置处于所述目标邻区的覆盖范围边缘，小区重选到该目标邻区的概率较低。因此，所述终端设备无需继续频繁对该目标邻区进行测量，所述终端设备对该目标邻区进行放松RRM测量，可以降低终端设备的功耗。
在本申请实施例中，终端设备可以根据服务小区的信号质量，来判断是否对所述目标邻区执行放松RRM测量。当通信系统中管理所述服务小区的基站使用波束赋形技术时，所述服务小区可以支持发送多个参考信号，例如图6所示。在一种实施方式中，所述基站可以针对所述目标邻区，在所述服务小区的p个参考信号中确定q个评估参考信号，以便于所述终端设备可以通过所述q个评估参考信号的信号质量，准确地判断是否对所述目标邻区执行放松RRM测量，具体步骤包括：
a、所述基站针对所述目标邻区，在所述服务小区的p个参考信号中选择所述q个评估参考信号。其中，所述基站可以通过多种方法在所述p个参考信号中，确定所述目标邻区的q个评估参考信号。示例性的，所述基站可以根据以下至少一项或组合，确定所述q个评估参考信号：所述服务小区的覆盖范围、管理所述服务小区的基站的位置、所述目标邻区的覆盖范围、管理所述目标邻区的基站的位置，以及发送所述p个参考信号的波束的方向。又例如，所述基站在所述p个参考信号中随机选择所述q个评估参考信号。
b、所述基站向所述终端设备发送所述目标小区的评估参考信号指示，所述评估参考信号指示用于指示所述q个评估参考信号。所述终端设备从所述基站接收所述目标小区的评估参考信号指示。
通过该实施方式，基站可以利用服务小区的参考信号的波束方向信息，对不同波束方向上的邻区进行更精细的放松RRM测量判决，进而保证提高判断对所述目标邻区执行放松RRM测量的准确性，最终可以保证终端设备的通信性能和降低终端设备的功耗。
在该实施方式下，所述终端设备在执行S402a时，确定所述服务小区的信号质量在所述目标邻区对应的信号质量范围内，包括：
所述终端设备确定所述服务小区的q个评估参考信号的信号质量；
所述终端设备确定所述q个评估参考信号的信号质量均在所述信号质量范围内。
通过以上描述，所述目标邻区对应的信号质量范围可以包含两个子范围：大于所述高门限Td relax，tall_ser，小于所述低门限Td relax，short_ser。为了提高终端设备确定执行放松RRM测量的准确性，在本申请实施例中，所述终端设备确定所述q个评估参考信号的信号质量在所述信号质量范围内，包括：所述终端设备确定所述q个评估参考信号的信号质量均在所述信号质量范围包含的一个子范围内。
在一种实施方式中，所述评估参考信号指示可以为比特图(bitmap)。
在一种场景中，当该目标小区发送的参考信号为SSB时，所述比特图的长度为协议规定的服务小区所在频点(服务频点)支持的SSB最大个数，例如，4bit、8bit或64bit。所述比特图的代码如下：
Figure PCTCN2021079377-appb-000001
比特图中每个比特位可以代表一个SSB，例如，比特图中首个比特位代表索引号为0的SSB是否为评估参考信号。所述终端设备可以通过每个比特位的取值来判断该比特位代表的SSB是否为评估参考信号。例如，比特位i取值为“0”表示索引号为i的SSB不是评估参考信号，比特位i的取值为“1”表示索引号为i的SSB为评估参考信号。
例如，在图2所示场景中，终端设备的服务小区为小区1，小区1所在的频点为f1。小区2和小区3为小区1的异频邻区，所在的频点分别为f2和f3。频点f1上能支持最多发送8个SSB，而管理小区1的基站为小区1配置7个SSB，在7个不同的波束方向上分别发送SSB。
管理小区1的基站选择小区1的SSB0-SSB6为小区2的评估参考信号，那么向终端设备发送小区2的评估参考信号指示——ssb-ToEvaluate＝11111110，并配置小区2的放松RRM测量配置参数为低门限Td relax，short_cell2。这样，当所述终端设备测量到小区1的参考信号SSB0-SSB6的信号质量都低于Td relax，short_cell2时，对小区2执行放松RRM测量。
管理小区1的基站选择小区1的SSB4-SSB6为小区3的评估参考信号，那么向终端设备发送小区3的评估参考信号指示——ssb-ToEvaluate＝00001110，并配置小区3的放松RRM测量配置参数包含高门限Td relax，tall_cell3和低门限Td relax，short_cell3。这样，当所述终端设备测量到小区1的参考信号SSB4-SSB6的信号质量都低于其他SSB的信号质量，或者当 小区1的参考信号SSB4-SSB6的信号质量均大于高门限Td relax，tall_cell3(或均小于低门限Td relax，short_cell3)时，所述终端设备对小区3执行放松RRM测量。
在另一种场景中，当该服务小区发送的参考信号为CSI-RS时，所述比特图的长度可以为协议支持的用于RRM测量的CSI-RS最大个数。每个比特位代表一个CSI-RS，例如，比特图中首个比特位代表ID为0的CSI-RS，比特位i代表ID为i的CSI-RS。所述终端设备可以通过该比特位的取值来判断该比特位代表的CSI-RS是否为评估参考信号。例如，比特位i取值为“0”表示ID为i的CSI-RS不是评估参考信号，比特位i的取值为“1”表示ID为i的CSI-RS为评估参考信号。
通过本申请实施例提供的以上RRM测量方法，所述终端设备可以在确定服务小区的信号质量在任一邻区的信号质量对应的信号质量范围内时，确定对该邻区进行放松RRM测量，从而可以节省终端设备功耗。另外，所述终端设备通过该方法，可以以邻区为粒度确定是否需要执行放松RRM测量，可以灵活地实现对每个邻区的放松RRM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。
为了使终端设备能够灵活地实现对目标频点上的邻区执行放松RRM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RRM测量方法。该方法可以适应于图1所示的通信系统中，下面参阅图4B，对本申请实施例提供的方法进行详细说明。
S401b：终端设备接收基站发送的重选配置信息，并按照传统的RRM测量方法，根据所述重选配置信息中的重选配置参数，对所有目标频点上的邻区和服务小区进行RRM测量。
具体过程可以参考图3所示的实施例中的S301中的描述，此处不再赘述。
S402b：所述终端设备确定任一目标频点上的任一邻区的信号质量在所述邻区对应的信号质量范围内时，对所述邻区执行放松RRM测量。
需要说明的是，本申请实施例中所述终端设备可以针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中的任一类目标频点执行上述步骤。
其中，所述终端设备对该邻区执行放松RRM测量，与图3所示的实施例中S302中终端设备对第一邻区执行放松RRM测量的方法相同，即通过增加所述邻区的检测时延、测量时延或评估时延，进而降低所述终端设备对该邻区进行测量的频率。所述终端设备可以具体通过以下步骤实现对所述邻区的放松RRM测量：
所述终端设备可以根据以下至少一项或组合时延指标，对所述邻区执行放松RRM测量：
第一检测时延T detect，relax_y、第一测量时延T measure，relax_y，和/或，第一评估时延T evaluate， relax_y；其中，所述T detect，relax_y>非放松RRM测量时所述目标频点的检测时延T detect，y，所述T measure，relax_y>非放松RRM测量时所述目标频点的测量时延T measure，y，所述T evaluate，relax_y>非放松RRM测量时所述目标频点的评估时延T evaluate，y。
示例性的，以上用于放松RRM测量的三个时延指标中的任一项可以为预设的时间长度。例如所述T measure，relax_y可以设置为7分钟或8分钟等具体数值。
示例性的，以上用于放松RRM测量的三个时延指标中的任一项可以其对应的非放松RRM测量时的时延指标的整数倍。例如，所述T detect，relax_y为所述T detect，y的整数倍；所述 T measure，relax_y为所述T measure，y的整数倍；所述T evaluate，relax_y为所述T evaluate，y的整数倍。
其中，以上用于放松RRM测量的三个指标的取值可以为协议规定的，或者由基站通过重选配置信息或RRC消息发送给所述终端设备的。
在一种实施方式中，所述终端设备可以通过以下方式，确定所述邻区对应的信号质量范围：
所述终端设备从基站接收所述邻区的放松RRM测量配置参数；
所述终端设备根据所述邻区的放松RRM测量配置参数，确定所述邻区对应的信号质量范围。
可选的，所述邻区的放松RRM测量配置参数中包含高门限Td relax，tall_c1，和/或，低门限Td relax，short_c1；其中，当所述邻区的放松RRM测量配置参数中包含所述Td relax，tall_c1时，所述邻区对应的信号质量范围包含：大于所述Td relax，tall_c1；当所述邻区的放松RRM测量配置参数中包含所述Td relax，short_c1时，所述邻区对应的信号质量范围包含：小于所述Td relax， short_c1。
需要说明的是，所述Td relax，tall_c1可以大于或等于向该邻区重选的信号质量门限Td x，c1；所述Td relax，short_c1小于所述Td x，c1。
示例性的，所述邻区的放松RRM测量配置参数可以携带在重选配置信息或RRC消息中由基站发送给所述终端设备。
通过以上步骤，所述基站设置高门限，以使终端设备测量到该邻区的信号质量大于该高门限时对该邻区执行放松测量。由于终端设备测量到该邻区的信号质量大于该高门限，因此，所述终端设备本次重选到该邻区的概率较高，那么若所述终端设备重选到该邻区后，后续无需继续频繁对该邻区进行测量。因此，该方法可以通过设置高门限，降低终端设备的功耗。
相反的，所述基站设置低门限，以使终端设备测量到该邻区的信号质量小于该低门限时执行放松测量。由于终端设备测量到该邻区的信号质量小于该低门限，因此，所述终端设备在较长时间内重选到该邻区的概率较低，因此无需继续频繁对该邻区进行测量。综上，该方法可以通过设置低门限，降低终端设备的功耗。
通过本申请实施例提供的以上RRM测量方法，所述终端设备通过任一邻区的信号质量在该邻区对应的信号质量范围内时，确定后续重选到该邻区的概率较低，因此，可以通过对该邻区进行放松RRM测量，从而可以节省终端设备功耗。另外，所述终端设备通过该方法，可以以邻区为粒度确定是否需要执行放松RRM测量，可以灵活地实现对每个邻区的放松RRM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。
为了使终端设备能够灵活地实现对目标频点上的邻区执行放松RRM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RRM测量方法。该方法可以适应于图1所示的通信系统中，下面参阅图5，对本申请实施例提供的方法进行详细说明。
S501：终端设备接收基站发送的重选配置信息，并按照传统的RRM测量方法，根据所述重选配置信息中的重选配置参数，对所有目标频点上的邻区和服务小区进行RRM测量。
具体过程可以参考图3所示的实施例中的S301中的描述，此处不再赘述。
S502：所述终端设备确定服务小区的信号质量在所述服务小区对应的信号质量范围内时，对在每个目标频点上的每个邻区执行放松RRM测量。
其中，在本申请实施例中，所述终端设备可以通过增加邻区的检测时延、测量时延和评估时延，进而降低对每个邻区的测量频率，具体过程可以参考图4A或图4B所示的实施例中对邻区执行放松RRM测量的具体描述，此处不再赘述。
在一种实施方式中，所述终端设备可以通过以下方式，确定所述服务小区的信号质量范围：
所述终端设备从基站接收所述服务小区的放松RRM测量配置参数；
所述终端设备根据所述服务小区的放松RRM测量配置参数，确定所述服务小区对应的信号质量范围。
可选的，所述服务小区的放松RRM测量配置参数中包含：高门限Td relax，tall_ser，和/或，低门限Td relax，short_ser；其中，当所述服务小区的放松RRM测量配置参数中包含所述Td relax，tall_ser时，所述服务小区对应的信号质量范围中包含：大于所述Td relax，tall_ser；当所述服务小区的放松RRM测量配置参数中包含所述Td relax，short_ser时，所述服务小区对应的信号质量范围中包含：小于所述Td relax，short_ser。
需要说明的是，所述Td relax，tall_ser可以大于触发邻区测量的服务小区信号质量门限，而所述低门限Td relax，short_ser小于所述Td relax，tall_ser。
示例性的，所述服务小区的放松RRM测量配置参数可以携带在重选配置信息或RRC消息中由基站发送给所述终端设备。通过以上步骤，所述基站设置高门限，以使终端设备在测量到服务小区的信号质量大于该高门限时对所有邻区执行放松测量。由于终端设备测量到服务小区的信号质量大于该高门限，因此，当前服务小区的信号质量较稳定，因此所述终端设备发生小区重选的概率较低，无需频繁对邻区进行测量。因此，该方法可以通过设定高门限，对所有邻区执行放松RRM测量，从而可以降低终端设备的功耗。
相反的，所述基站设置低门限，以使终端设备测量到服务小区的信号质量低于该低门限时执行放松测量。由于终端设备测量到服务小区的信号质量小于该低门限，因此，所述终端设备重选到邻区的概率较高，那么当所述终端设备重选到邻区后，无需继续频繁对所有邻区进行测量。因此，该方法可以通过设置低门限，降低终端设备的功耗。通过本申请实施例提供的以上RRM测量方法，所述终端设备通过服务小区的信号质量在该服务小区对应的信号质量范围内时，确定后续发生小区重选的概率较低，因此，所述终端设备可以对所有邻区进行放松RRM测量，从而可以节省终端设备功耗。另外，所述终端设备通过该方法，通过服务小区的信号质量来判断是否对所有邻区执行放松RRM测量，可以灵活地实现对邻区的放松RRM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。
随着大规模天线技术的发展，为了满足用户对通信系统的传输速率和系统容量等方面的需求，在图1所示的通信系统可以引入波束赋形技术。波束赋形是一种基于天线阵列的信号预处理技术，通过调整天线阵列中每个阵源的加权系统，以产生具有指向性的波束，从而能够得到明显的传输增益。如图6所示，基站可以具有8个不同方向的波束，并通过波束来传输信号。因此，在图3-图5所示的实施例中，管理服务小区或任一个邻区的基站可以通过多个波束发送多个参考信号，其中一个波束对应一个参考信号。如图6所示，基 站可以通过波束0-波束7分别发送SSB0-SSB7。
在支持波束赋形技术的通信系统场景中，显然所述终端设备在对服务小区或邻区进行RRM测量后，可以得到该小区的多个参考信号的信号质量。目前，终端设备一般将测量到的多个参考信号的信号质量平均值，作为该小区的信号质量。使用这种方法确定的小区信号质量，没有利用参考信号的波束方向信息，不能对位于不同波束方向上的邻区进行更精细的放松RRM测量判决，进而导致远离邻区覆盖范围的位置仍不能放松RRM测量，导致终端设备功耗的浪费。基于此，本申请还提供了一种RRM测量方法，下面参阅图7所示的流程图，对该方法的流程进行详细说明。
S701：针对支持波束赋形技术的待测量的目标小区，基站在该目标小区的n个参考信中确定用于进行RRM测量的m个测量参考信号，其中，n和m为正整数，且m<n。
其中，所述基站可以通过多种方法在所述n个参考信号中确定所述至少一个测量参考信号。示例性的，所述基站可以根据所述目标小区的覆盖范围，管理所述目标小区的基站的位置，以及发送所述n个参考信号的波束的方向，确定所述m个目标参考信号。又例如，所述基站在所述n个参考信号中随机选择所述m个测量参考信号。
需要说明的是，所述目标小区可以为终端设备的服务小区，或者为在任一个目标频点上的邻区，本申请对此不作限定。所述基站为管理所述服务小区的基站。
S702：所述基站向终端设备发送所述目标小区的测量参考信号指示，所述测量参考信号指示用于指示所述m个测量参考信号。所述终端设备从所述基站接收所述目标小区的测量参考信号指示。
可选的，所述目标小区的测量参考信号指示可以携带在重选配置信息中或者RRC消息中。
S703：所述终端设备在对所述目标小区进行RRM测量时，根据所述测量参考信号指示，对所述目标小区的所述m个测量参考信号进行测量，得到所述m个测量参考信号的信号质量。
所述终端设备在获得所述m个测量参考信号的信号质量后，可以根据所述m个参考信号的信号质量，确定所述目标小区的信号质量。通过该方法，所述基站针对每个支持波束赋形技术的小区，指定其用于进行RRM测量的测量参考信号，进而提高确定小区的信号质量的灵活性。
示例性的，在本申请实施例中，所述终端设备可以将所述m个测量参考信号的信号质量均作为所述目标小区的信号质量。这样，在以上实施例中，当所述终端设备在根据所述目标小区的信号质量是否满足相应条件，来判断是否应该执行放松RRM测量、是否触发对邻区进行RRM测量，以及是否进行小区重选过程中，可以通过判断该m个测量参考信号中每个测量参考信号的信号质量是否均满足该相应条件。
例如，在图3所示的实施例中，所述终端设备在确定测量到的服务小区的信号质量在T speed_ser内的变化量小于Td speed_ser，包括：
所述终端设备确定测量到的所述服务小区的m个测量参考信号中每个测量参考信号的信号质量在所述T speed_ser内的变化量均小于Td speed_ser。
又例如，在图4B所示的实施例中，所述终端设备在确定任一邻区的信号质量在所述邻区对应的信号质量范围内时，包括：
所述终端设备确定测量到的所述邻区的m个测量参考信号中每个测量参考信号的信 号质量均在该邻区对应的信号质量范围内。
还需要说明的是，在图4B和图5所示的实施例中，服务小区或邻区对应的信号质量范围可以包含两个子范围：大于高门限Td relax，tall、小于低门限Td relax，short。为了提高终端设备确定执行放松RRM测量的准确性，在本申请实施例中，所述终端设备在确定目标小区的每个测量参考信号的信号质量均在该目标小区对应的信号质量范围内，可以为：
所述终端设备确定所述目标小区的m个测量参考信号中每个测量参考信号的信号质量均在所述该目标小区对应的信号质量范围包含一个子范围内。
继续以图4B中的实施例为例，所述终端设备在确定该邻区的m个测量参考信号中每个测量参考信号的信号质量均小于低门限Td relax，short_c1时，对该邻区执行放松RRM测量。所述终端设备在确定该邻区m个测量参考信号中每个测量参考信号的信号质量均大于高门限Td relax，tall_c1时，所述终端设备对该邻区执行放松RRM测量。
需要说明的是，终端设备接入的基站可以同时对服务小区和待测量邻区中所有支持波束赋形技术的多个目标小区执行上述过程，这样，所述终端设备可以根据接收到的每个目标小区的测量参考信号指示，对每个目标小区执行RRM测量。
在一种实施方式中，所述测量参考信号指示可以为比特图(bitmap)。
在一种场景中，当该目标小区发送的参考信号为SSB时，所述比特图的长度为协议规定的该目标小区所在频点支持的SSB最大个数，例如，4bit、8bit或64bit。所述比特图的代码如下：
Figure PCTCN2021079377-appb-000002
比特图中每个比特位可以代表一个SSB，例如，比特图中首个比特位代表索引号为0的SSB是否为测量参考信号。所述终端设备可以通过每个比特位的取值来判断该比特位代表的SSB是否为测量参考信号。例如，比特位i取值为“0”表示索引号为i的SSB不是测量参考信号，比特位i的取值为“1”表示索引号为i的SSB为测量参考信号。
例如，在图2所示场景中，终端设备的服务小区为小区1，小区1所在的频点为f1。小区2和小区3为小区1的异频邻区，所在的频点分别为f2和f3。频点f1、f2和f3上能支持最多发送8个SSB，而管理小区1的基站为小区1配置7个SSB，在7个不同的波束方向上分别发送SSB。
管理小区1的基站选择小区2中的SSB0-SSB6为测量参考信号，那么向终端设备发送小区2的测量参考信号指示——ssb-Tomeasure＝11111110，并配置小区2的放松RRM测量配置参数为低门限Td relax，short_cell2。这样，当所述终端设备测量到小区2的测量参考信号SSB0-SSB6的信号质量都低于Td relax，short_cell2时，对小区2执行放松RRM测量。
管理小区1的基站选择小区3中的SSB4-SSB6为测量参考信号，那么向终端设备发送小区3的测量参考信号指示——ssb-Tomeasure＝00001110，并配置小区3的放松RRM测量配置参数包含高门限Td relax，tall_cell3和低门限Td relax，short_cell3。这样，当所述终端设备测量到小区3的测量参考信号SSB4-SSB6的信号质量都低于其他SSB的信号质量，或者当SSB4-SSB6的信号质量均大于高门限Td relax，tall_cell3(或均小于低门限Td relax，short_cell3)时， 所述终端设备对小区3执行放松RRM测量。
在另一种场景中，当该目标小区发送的参考信号为CSI-RS时，所述比特图的长度可以协议支持的用于RRM测量的CSI-RS最大个数。每个比特位代表一个CSI-RS，例如，比特图中首个比特位代表ID为0的CSI-RS，比特位i代表ID为i的CSI-RS。所述终端设备可以通过该比特位的取值来判断该比特位代表的CSI-RS是否为测量参考信号。例如，比特位i取值为“0”表示ID为i的CSI-RS不是测量参考信号，比特位i的取值为“1”表示ID为i的CSI-RS为测量参考信号。
通过本申请实施例提供的以上RRM测量方法，针对每个支持波束赋形技术的目标小区，基站可以在其多个参考信号中选择用于终端设备进行测量的测量参考信号，以便使终端设备测量到的测量参考信号的信号质量，可以更准确地反映出该目标小区的信号质量，进而可以提高终端设备的小区重选准确性。
基于相同的技术构思，本申请实施例还提供了一种通信装置，该装置的结构如图8所示，包括通信单元801和处理单元802。所述通信装置可以应用于图1所示的通信系统中的基站或终端设备，并可以实现以上各个实施例中提供的RRM测量方法。下面对装置800中的各个单元的功能进行介绍：

所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
