Description

测量小区的方法与装置
本申请要求于2022年09月21日提交中国专利局、申请号为202211153981.4、申请名称为“一种监测LP-WUS时邻区测量的方法”的中国专利申请的优先权以及2022年10月29日提交中国专利局、申请号为202211340811.7、申请名称为“测量小区的方法与装置”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，尤其涉及一种测量小区的方法与装置。
背景技术
在移动通信网络中，当终端设备需要切换至信号更强的小区时，终端设备需要对邻区的信号强度或质量进行测量。
但是相关技术中，仅有终端设备通过其包括的主接收机进行邻区测量的方案，导致终端设备功耗较大。
发明内容
本申请提供了一种测量小区的方法与装置，可以降低终端设备进行小区测量时的功耗。
第一方面，本申请提供一种测量小区的方法，应用于终端设备，包括：接收第一信息，第一信息用于指示至少两个小区各自的测量参考信号对应的时间区间，其中，至少两个小区各自的测量参考信号对应的时间区间在时域上不重叠；根据第一信息进行小区测量。
本申请中，至少两个小区具体是指至少两个邻区。
其中，至少两个小区各自的测量参考信号对应的时间区间在时域上不重叠，可以理解为至少两个小区中不同小区的测量参考信号是在不同的时间进行发送的。
其中，根据第一信息进行小区测量，具体包括：接收至少两个小区中每个小区的基站在其小区对应的时间区间内发送的测量参考信号，以及对每个小区的测量参考信号进行处理，得到每个小区的测量结果。
本申请提供的技术方案中，由于不同小区的测量参考信号是在不同的时域上发送的，因此，即使终端设备是在WUR链路上进行工作，终端设备也能够区分出不同小区的测量参考信号，从而基于每个时间区间上接收的测量参考信号进行处理得到对应小区的测量结果，完成对应小区的测量。也就是说，该技术方案，可以实现终端设备在WUR链路上的小区测量，从而降低终端设备进行小区测量时的功耗。
结合第一方面，在一种可能的实现方式中，至少两个小区中每个小区的测量参考信号包括用于指示其小区的小区标识的信息。
其中，至少两个小区中每个小区的测量参考信号包括用于指示其小区的小区标识的信息，也可以描述为至少两个小区中每个小区的测量参考信号包括用于指示该小区的小区标识的信息
该实现方式中，由于每个小区的测量参考信号中包括了用于指示该测量参考信号的小区标识的信息，因此，可以实现终端设备从测量参考信号中确定出当前进行处理的测量参考信号对应的具体的小区。
结合第一方面，在一种可能的实现方式中，所述方法还包括：接收第二信息，第二信息用于指示至少两个小区中每个小区的测量参考信号对应的时间区间与其小区标识信息之间的对应关系。
该实现方式中，由于通过第二信息向终端设备指示了至少两个小区中每个小区的测量参考信 号对应的时间区间与其小区标识信息之间的对应关系。因此，对于终端设备而言，就可以基于第二信息，在对每个时间区间上接收的测量参考信号进行处理时，确定出当前时间区间对应的小区标识信息，从而确定出在当前时间区间上处理的测量参考信号对应的具体的小区。
结合第一方面，在一种可能的实现方式中，第一信息中包括以下信息中的至少一项：用于指示至少两个小区中每个小区的测量参考信号对应的时间区间的周期信息，用于指示至少两个小区中每个小区的测量参考信号对应的时间区间的偏移值信息、用于指示至少两个小区中每个小区的测量参考信号对应的时间区间的时域长度信息。
该实现方式中，可以通过周期信息、偏移值信息和时域长度信息中的至少一项来配置每个小区的时间区间。
结合第一方面，在一种可能的实现方式中，根据第一信息进行小区测量，包括：根据第一信息和第三信息进行小区测量，第三信息用于指示在对至少两个小区进行测量时每个小区对应的测量周期。
该实现方式中，由于为每个小区配置了测量周期，使得终端设备在对每个小区进行测量时，可以从每个小区对应的多个时间区间中选择出一个时间区间并在该一个时间区间上进行小区测量。
结合第一方面，在一种可能的实现方式中，至少两个小区对应M个频点，M为正整数。可选地，M个频点具有优先级。
示例性地，至少两个小区对应的M个频点可以是具有相同的优先级，也可以是具有不同的优先级。
该实现方式中，通过为每个小区对应的频点配置优先级，可以使得终端设备在进行小区测量时还考虑每个小区对应的频点的优先级，进一步地，有助于终端设备在进行小区测量时选择更合适的小区。
结合第一方面，在一种可能的实现方式中，至少两个小区中第一小区的频点的优先级高于第二小区的频点的优先级，第一小区的测量参考信号的时间区间的周期小于第二小区的测量参考信号的时间区间的周期。
该实现方式中，在第一小区的频点的优先级高于第二小区的频点的优先级时，由于将第一小区的测量参考信号的时间区间的周期配置得小于第二小区的测量参考信号的时间区间的周期，因此可以满足对频点的优先级较高的小区的测量比较频繁，而对频点的优先级较低的小区的测量不需要特别频繁的需求。
结合第一方面，在一种可能的实现方式中，根据第一信息进行小区测量，包括：在服务小区的测量参考信号的测量结果小于或等于第一门限值时，根据第一信息进行小区测量。
其中，当服务小区的测量参考信号的测量结果小于或等于第一门限值时，可以说明当前服务小区的信号质量是比较差的。也就是说，该实现方式中，可以在服务小区的信号质量是比较差的情况下，再去进行小区测量。因此，有助于进一步降低终端设备进行小区测量时的功耗。
结合第一方面，在一种可能的实现方式中，根据第一信息进行小区测量，包括：对频点的优先级高于第一优先级的小区进行测量；以及，在服务小区进行测量的测量结果小于或等于第二门限值时，对频点的优先级等于或低于第一优先级的小区进行测量，第一优先级为服务小区的频点的优先级。
该实现方式中，也将优先级高于第一优先级的频点也称为高优先级的频点，将优先级等于或低于第一优先级的频点也称为中低优先级的频点。换句话说，该实现方式中，对高优先级的频点始终在WUR链路上测量，而对于中低优先级的频点采用上述所描述的通过第一门限值来确定是否进行测量。
结合第一方面，在一种可能的实现方式中，小区测量的测量结果包括测量参考信号在第一时频资源中的测量结果，第一时频资源包括第一时域资源和第一频域资源，第一时域资源为时间区间上接收的测量参考信号所占用的时间单元，第一频域资源为测量参考信号的部署带宽。
其中，测量参考信号的部署带宽也等同于终端设备的接收带宽。

结合第一方面，在一种可能的实现方式中，小区测量的测量结果还包括接收的测量参考信号的第一接收质量，第一接收质量为K*第一时频资源中的测量结果/第二时频资源内接收到的总功率。结合第一方面，在一种可能的实现方式中，小区测量的测量结果还包括目标误块率，目标误块率为终端设备接收到的唤醒信号校验不通过的比例。

本申请实施例提供一种测量小区的方法与装置，其中，方法、装置是基于同一技术构思的，由于方法、装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例提供的技术方案可以应用于各种通信***。例如，所应用的通信***可以为全球移动通讯(global system of mobile communication，GSM)***，码分多址(code dividion multiple access，CDMA)***、宽带码分多址(wideband radio service，GPRS)、长期演进(long term evolution，LTE)***，高级的长期演进(LTE advanced，LTE-A)、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)***、通用移动通信***(universal mobile telecommunication system，UMTS)、第五代移动通信***、以及未来的一些通信***(例如第六代移动通信***)等。
下面，结合附图，对本申请实施例进行详细描述。
首先，结合图1说明适用于本申请实施例的通信***。图1示出了适用于本申请实施例的适用的通信***的示意图，如图1所示，该通信***包括网络设备101和终端设备102。
其中，网络设备101可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved NodeB，eNB或eNodeB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base stationcontroller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，homeevolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and receptionpoint，TRP)等，还可以为5G，如，NR，***中的gNB，或，传输点(TRP或TP)，5G***中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)或分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，例如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成物理层的信息，或者，由物理层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+CU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
终端设备102可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以称为用户设备(user equipment，UE)、接入终端(access terminal)、用户单元(user unit)、用户站(user station)、移动站(mobile station)、移动台(mobile)、远方站(remote station)、远程终端(remote terminal)、移动设备(mobile equipment)、用户终端(user terminal)、无线通信设备(wireless telecom equipment)、用户代理(user agent)、用户装备(user equipment)或用户装置。终端设备可以是无线局域网(wireless local Area networks，WLAN)中的站点(station，STA)，可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信***(例如，第五代(fifth-generation，5G)通信网络)中的终端或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端设备等。其中，5G还可以被称为新空口(new radio，NR)。本申请一种可能的应用的场景中，终端设备也可以为经常工作在地面的终端设备，例如车载设备。在本申请中，为了便于叙述，部署在上述设备中的芯片，或者芯片也可以称为终端设备。
本申请中，网络设备和终端设备之间可以通过授权频谱进行通信，也可以通过非授权频谱进行通信，也可以同时通过授权频谱和非授权频谱进行通信。网络设备和终端设备之间可以通过6千兆赫(gigahertz，GHZ)以下的频谱进行通信，也可以通过该6GHZ以上的频谱进行通信，还 可以同时使用6GHZ以下的频谱和6GHZ以上的频谱进行通信。本申请实施例对网络设备和终端设备之间所使用的频谱资源不做限定。
可以理解的是，图1中示出的终端设备的数量仅是一种示例。
应注意，在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作***层，以及运行在操作***层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作***可以是任意一种或多种通过进程(process)实现业务处理的计算机操作***，例如，Linux操作***、Unix操作***、Android操作***、iOS操作***或windows操作***等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可。例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面的方法可以使用编程方式实现，并形成计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
对于图1所示的通信***中的终端设备，无论是在空闲(idle)态/非激活(inactive)态下执行接收寻呼，还是在连接态进行数据接收，都可以使用终端设备中的主接收机(或者称为主电路)完成这些功能。本实施例中，将终端设备使用主接收机接收信号也称为在主链路上工作，或者也称为主接收机处于工作状态。可以理解，主电路(或主接收机)仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。下文为便于说明，统一描述为主电路。
终端设备使用主电路接收的信号可以被称为在主链路上传输，其中，主链路表征了终端设备和网络设备间的一种连接关系，是一个逻辑概念，而非一个物理实体。可以理解，主链路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。
此外，为了降低终端设备的功耗，终端设备还可以通过使用一个单独的低功耗小电路接收信号。该低功耗小电路可以使用一个结构简单的单独的小电路或芯片实现，其功耗较低。该低功耗小电路例如可以称为唤醒无线电(wake up radio，WUR)，或者也可以称为唤醒电路，或者也可以称为低功耗电路，或者也可以称为唤醒接收机(wake up receiver，WUR)，等等，关于其命名，本申请不予限制。在本申请中，为便于描述，将该低功耗小电路称为唤醒电路。可以理解，唤醒电路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。下文为便于说明，统一描述为唤醒电路。
其中，该WUR模块用于接收网络设备发送的唤醒信号(wake up signal，WUS，也被称为低功耗唤醒信号low power wake up signal,LP-WUS)，并根据WUS中承载的信息比特解调出唤醒指示信息，从而唤醒终端设备中关闭的(或处于睡眠状态的)主接收机或主接收模块。本实施例中，将终端设备使用WUR模块接收唤醒信号也称为在WUR链路上工作，或者也称为WUR模块处于工作状态。
其中，唤醒信号，可用于唤醒至少一个终端设备或者至少一组终端设备。作为示例，唤醒信号中包括唤醒信息，唤醒信息表示与唤醒终端设备相关的信息，唤醒信息例如为与寻呼相关的信息。唤醒信息例如可以用于终端设备确定是否要执行寻呼接收的流程，又如可以用于终端设备确定是否要发起随机接入。作为示例，唤醒信息包括：需要唤醒的一个或多个终端设备的信息(如UE ID)。其中，该一个或多个终端设备，也可以为终端设备组(UE group)的形式，相应地，唤醒信息可以包括该终端设备组的组标识。
具体地，当网络设备向终端设备发送WUS时，目前为了降低WUR模块的功耗，WUS信号通常采用开关键控(on off keying，OOK)或曼彻斯特OOK等一些简单的调制方法，相应地，终端设备中的WUR模块采用包络检波的方式接收WUS。
示例性地，在基于OOK进行调制时，会通过一个高电平来表示信息比特1，而通过一个低电平来表示信息比特0。或者反之，通过一个低电平来表示信息比特1，而通过一个高电平来表示信息比特0。在该方案中，高电平和低电平可以认为是用来表示不同信息比特的两个符号，本申请中，分别称为高电平符号和低电平符号(也统称为OOK符号)。
例如，假设唤醒信号为0011010100，那么在使用OOK进行调制时，若通过高电平表示信息比特1和低电平表示信息比特0，那么如图2所示，将分别对应低电平符号、低电平符号、高电平符号、高电平符号、低电平符号、高电平符号、低电平符号、高电平符号、低电平符号、低电平符号，其中，低电平符号表示信息比特0，高电平符号表示信息比特1。
应理解，对于包括WUR模块的终端设备而言，当在WUR链路上工作时，终端设备也可能出现需要对邻区的信号强度或质量进行测量的情况，以使得终端设备可以切换至信号质量更好的小区。但是相关技术中，仅有终端设备通过其包括的主接收机对邻区的信号强度或质量进行测量的方法，在这种情况下，若终端设备需要对邻区的信号强度或质量进行测量时，一种实施方案为：终端设备时不时打开主接收机，然后在主接收机上进行邻区测量。但是，这种实施方案无疑会使得终端设备的功耗较高。
鉴于此，本申请提出一种测量小区的方法与装置。本申请提供的测量小区的方法中，可以实现终端设备在WUR链路上工作时也能够进行小区测量，从而降低终设备的功耗。
需要说明的是，本申请中的测量“小区”指的是测量“邻区”。为便于描述，本申请将测量小区也称为测量邻区。
图3为本申请一个实施例提供的测量邻区的方法。如图3所示，该方法包括S301和S302。
S301，第一网络设备向终端设备发送第一信息，第一信息用于指示至少两个小区各自的测量参考信号对应的时间区间，其中，至少两个小区各自的测量参考信号对应的时间区间在时域上不重叠；相应地，终端设备接收第一信息。
本实施例中，第一网络设备是指当前服务于终端设备的服务小区的基站或者核心网设备。
本实施例中，至少两个小区具体是指至少两个邻区。
通常，终端设备中的主链路在进行小区测量时，其可以基于接收的同步信号块(synchronization signal block，SSB)中的辅同步信号执行小区测量。具体地，由于辅同步信号是一个复数序列，即辅同步信号既有幅度也有相位，因此不同小区的辅同步信号重叠时，终端设备可以通过同步信号的正交性从接收的信号提取出不同小区分别对应的辅同步信号，从而可以确定出对应每个小区的信号接收功率。或者换句话说，当终端设备在主链路上进行小区测量时，若终端设备在相同的时间和频率位置上接收到多个小区的辅同步信号，那么终端设备也能够分别提取出各个小区的辅同步信号，从而确定出各个小区的信号接收功率是多大。其中，有关主链路的概念可以参考本申请前述相关部分的描述，此次不再赘述。
但是，当终端设备在WUR链路上工作时，由于终端设备接收到的信号通常采用的是类似OOK或者曼彻斯特OOK等这种简单的调制方式以及终端设备对接收到的信号会采用包络检测的方式进行解调，这样将导致解调后的信号只保留了幅度信息而没有相位信息。在这种情况下，如果多个小区的用于终端设备进行测量的测量参考信号在重叠的时频资源上发送，那么会出现终端设备无法提取出各个小区的测量参考信号的问题，从而导致终端设备无法对小区进行准确的测量。在此说明的是，上述所述的在重叠的时频资源上发送，既包括在部分重叠的时频资源上发送，也包括在全部重叠的时频资源上发送。即，多个小区的用于终端设备进行测量的测量参考信号不论是在部分重叠的时频资源上发送，还是在全部重叠的时频资源上发送，都会出现端设备无法提取出各个小区的测量参考信号的问题，从而导致终端设备无法对小区进行准确的测量。
因此，为了使得终端设备也可以在WUR链路上进行小区测量，本申请中，让不同小区的测量参考信号在时间上相互正交，换言之，本申请中通过将不同小区的测量参考信号在不同的时间 发送的方式，来使得终端设备在WUR链路上工作时也能分别提取出不同小区的测量参考信号，从而基于不同小区中每个小区的测量参考信号完成对应小区的测量。
具体地，在实施时，网络设备向终端设备发送第一信息，该第一信息用于指示至少两个小区各自的测量参考信号对应的时间区间，且至少两个小区各自的测量参考信号对应的时间区间在时域上不重叠。本实施例中，将时间区间也称为时间窗(window)或者时机(occasion)或者时间位置(position)。
即，本实施例中，第一网络设备可以通过第一信息来配置每个小区的测量参考信号发送的时间窗，并且在配置时，任意两个不同的小区的测量参考信号发送的时间窗是不一样的。这样，终端设备就可以通过在不同的时间窗上接收不同小区的测量参考信号，以区分不同小区的测量参考信号，从而完成不同邻区的测量。
更具体地，在一种实施方案中，通过第一信息来配置每个小区的测量参考信号发送的时间窗时，第一信息中可以包括以下信息中的至少一项：用于指示每个小区的测量参考信号对应的时间区间的周期信息，用于指示每个小区的测量参考信号对应的时间区间的偏移值信息、用于指示每个小区的测量参考信号对应的时间区间的时域长度信息。也就是说，在该实施方案中，每个被配置的时间窗可以基于周期信息、偏移值信息和时域长度信息中的至少一项来配置。
应理解，对于至少两个小区，可能会包括与终端设备的服务小区的频点相同的小区(即同频小区)、也有可能包括与终端设备的服务小区的频点不同的小区(即异频小区)。本实施例中，将终端设备对同频小区的测量也称为同频测量，将终端设备对异频小区的测量也称为异频测量。
需要说明的是，本实施例中，在配置至少两个小区各自的测量参考信号对应的时间区间时，是基于不同的小区而非不同的频点考虑的，只要小区是不同的，那么配置的时间窗就是不同的。例如，即使N个小区中有两个小区的频点是相同的，此时为该频点相同的两个小区配置的时间窗也是不一样的。再换句话说，本实施中，一个时间窗仅会与一个小区对应，而不会出现一个时间窗同时与多个小区对应的情况。
示例性地，以同频测量为例，该示例以4个小区且该4个小区与服务小区的频点相同为例，如图4所示，可以在当前WUR的工作频段(WUR模块的接收带宽以及中心频点/WUR模块的部署带宽以及中心频点)下，除了唤醒信号所使用的时间区间外，还分别配置与4个小区一一对应的4个时间窗，其中，一个时间窗与一个小区对应，且不同的小区对应不同的时间窗。
示例性地，再以异频测量为例，该示例中假设需要测量的小区有9个，其中，4个小区的频点与终端设备的服务小区的频点相同(即4个同频小区)、2个小区的频点为异频频点1(与服务小同频点不同)，3个小区的频点为异频频点2(与服务小同频点不同)。如图5所示，可以在当前WUR的工作频段下，除了唤醒信号所使用的时间区间外，还分别配置与9个小区对应的9个时间窗。具体地，对于同频的4个小区，配置4个时间窗，对于异频频点1对应的2个小区配置2个时间窗，对于异频频点2对应的3个小区配置3个时间窗。
可选地，由于终端设备在对不同的频点的小区进行测量时，需要先将射频前端与频点进行对准，导致在不同的频点进行切换时产生切换时延。因此，为了避免频繁切换(切换需要预留retuning时间)，各个时间窗可以连续排布。
但是，在此说明的是，上述各个时间窗可以连续排布仅是一种实现方式，并不构成本申请的限制。示例性地，以图4为例，与服务小区的频点相同的4个小区对应的4个时间窗也可以不连续排布。又或者，以图5为例，与终端设备的服务小区的频点相同的4个同频小区对应的4个时间窗连续排布，异频频点1对应的2个时间窗不连续排布，异频频点2对应的3个时间窗不连续排布。
S302，终端设备根据第一信息进行小区测量。
具体地，本实施例中，终端设备根据第一信息进行小区测量，包括：至少两个小区中每个小区的基站(即发送测量参考信号的基站，本申请中也称为第二网络设备)在其小区对应的时间区间内发送测量参考信号，其中，每个小区对应的时间区间与其他小区对应的时间区间在时域上不重叠，相应地，终端设备接收每个小区的基站在其小区对应的时间区间内发送的测量参考信号， 并对每个小区的测量参考信号进行处理，得到至少两个小区中每个小区的测量结果。
应理解，终端设备在进行小区测量时，还需要确切的知道当前接收的测量参考信号是哪个小区的。
在第一种实施方案中，本实施例中的至少两个小区中每个小区的测量参考信号包括用于指示每个小区的小区标识的信息，这样，对于终端设备而言，在对每个时间区间上接收的测量参考信号进行处理时，就可以基于当前接收的测量参考信号中包括的用于指示每个小区的小区标识的信息确定出当前处理的测量参考信号对应的小区。
示例性地，假设至少两个小区中包括第三小区，则该第三小区的基站在对应的时间区间发送测量参考信号时，可以在该测量参考信号中包括用于指示第三小区的小区标识的信息，这样，终端设备可以基于接收的测量参考信号中用于指示第三小区的小区标识的信息确定出当前时间区间上所处理的测量参考信号是第三小区的。
在此说明的是，本申请对测量参考信号中如何包括用于指示每个小区的小区标识的信息的具体实现方式不做限制。
在一种实现方式中，参考信号中携带指示信息，指示信息指示小区标识。例如，参考信号的前一部分是一个用于测量的序列，后一部分携带若干比特的指示信息指示小区标识。此时，终端设备可以通过参考信号的前一部分进行测量，并根据后一部分的指示确定测量结果是哪个小区的。
在另一种实现方式中，参考信号所用的序列的生成参数中包括小区标识，即根据小区标识以及其他参数生成序列，并根据该序列生成参考信号。这种情况下，终端设备在对接收的后的信号进行处理时，需要进行盲检，例如使用不同小区标识对应的序列与接收信号做相关，有相关峰值的序列对应的小区标识可被认为是接收到的参考信号对应的小区标识。
在第二种实施方案中，若测量参考信号中不包括用于指示每个小区的小区标识的信息，那么第一网络设备还可以向终端设备发送第二信息，其中，该第二信息用于指示至少两个小区中每个小区的测量参考信号对应的时间区间与其小区标识信息之间的对应关系。相应地，对于终端设备而言，就可以基于第二信息，在对每个时间区间上接收的测量参考信号进行处理时，确定出当前时间区间对应的小区标识信息，从而确定出当前时间区间上的测量参考信号对应的具体的小区。
本实施例提供的测量小区的方法，由于终端设备是在不同的时间区间接收不同小区的测量参考信号的，因此，即使终端设备是在WUR链路上工作时，终端设备也可以区分出不同小区的测量参考信号，从而基于每个时间区间上接收的测量参考信号进行处理得到对应小区的测量结果，完成对应小区的测量。也就是说，该技术方案，可以实现终端设备在WUR链路上的小区测量，从而降低终端设备进行小区测量时的功耗。
作为一个可选的实施例，本申请中的至少两个小区可以对应M个频点，M为正整数。
进一步地，该M个频点还可以具有优先级。
在一种实施方案中，至少两个小区对应的M个频点的优先级可以复用主链路中配置的优先级。其中，主链路中配置的频点优先级包含在SIB2、SIB4以及SIB5中，SIB2中包含同频、异频、以及异***小区重选的公共信息，SIB4中包括异频小区重选的相关信息，SIB5中包括异***小区重选的相关信息。在上述SIB中，频点优先级通过参数cellReselectionPriority配置，其中，cellReselectionPriority是一个整数型变量，取值范围为0～7。
在另一种实施方案中，可以为WUR链路单独配置频点的优先级。例如，对于支持WUR链路的终端设备来说，应当尽可能多的工作在WUR链路上，以更大的降低终端设备的功耗。但是由于主链路在配置频点的优先级的时候，可能并不一定把部署了WUR链路的频点都设置为高优先级，这可能导致终端设备驻留到部署了WUR链路的频点的概率降低。因此可能还需要为WUR链路配置单独的频点的优先级。
应理解，存在至少两个小区对应的M个频点的优先级可能是不同的情况，应理解，对于不同优先级的频点，其测量要求通常是不同的，例如对于高优先级的频点，终端设备的测量应该比较频繁(即测量周期要求短)，而对于低优先级的频点，则不需要特别频繁(即测量周期要求长)。
在一种实施方案中，终端设备可以根据第一信息和第三信息进行小区测量，其中，第三信息 用于指示在对至少两个小区进行测量时每个小区对应的测量周期。具体地，在该实施例中，终端设备在对每个小区进行测量时，可以基于该每个小区的测量周期，从该每个小区对应的多个时间区间中选择出一个时间区间并在该一个时间区间上进行测量。
在另一种实施方案中，可以通过协议规定不同优先级的测量周期，然后终端设备在对每个小区进行测量时，可以基于协议规定的不同优先级的测量周期，获得每个小区的测量周期，然后基于该测量周期再进行每个小区的测量。
在另一种实施方案中，对于不同优先级的频点配置的时间区间的周期就不一样，然后让终端设备基于配置的时间窗口进行测量。更具体地：在配置高优先级频点的小区对应的时间区间和低优先级的频点的小区对应的时间区间时，可以使得高优先级频点对应的时间区间的周期小于低优先级频点对应的时间区间的周期。例如，假设至少两个小区中包括第一小区和第二小区，并且第一小区的频点的优先级高于第二小区的频点的优先级，那么可以让第一小区的测量参考信号的时间区间的周期小于第二小区的测量参考信号的时间区间的周期。
作为一个可选的实施例，本实施例中，当终端设备通过图3所述的测量小区的方法在WUR链路上完成对小区的测量后，终端设备还可以通过接收服务小区的测量参考信号完成对服务小区的测量，进一步地，再在WUR链路上基于服务小区和小区的测量结果做对比，判断是否需要进行小区重选。可选地，在一种情况下，当终端设备确定要重选到一个新的目标小区时，在WUR链路上其完成重选后，可以持续在WUR链路上工作。或者，在另一种情况下，当终端设备在WUR链路上完成重选后，先切换到主链路接受新的目标小区的一些配置信息，再根据新的目标小区中的情况确定是否到WUR链路上工作。
应理解，若服务小区的信号质量或强度比较好，此时终端设备也可以不进行小区测量，而若服务小区的信号质量或强度比较弱，那么终端设备应进行小区测量，以切换到信号质量或强度更高的小区。
因此，为了减少终端设备的测量，作为一个可选的实施例，还可以在WUR链路上定义减少终端设备的测量的方法。具体地：
在一种实施方案中，可以配置第一门限值，当终端设备在WUR链路上对服务小区的测量参考信号测得的测量结果高于该第一门限值时(说明当前服务小区的信号质量或强度是比较好的)，终端设备可以在WUR链路上不根据第一信息进行小区测量(不进行小区测量)；否则，当终端设备需要在WUR链路上根据第一信息进行小区测量，即当终端设备在WUR链路上对服务小区的测量参考信号测得的测量结果小于或等于第一门限值时(说明当前服务小区的信号质量或强度可能是比较弱的)，再进行小区测量。
在另一种实施方案中，还可以对不同优先级的频点分别处理。具体地，可以对于频点的优先级高于第一优先级的小区进行测量，以及，在服务小区进行测量的测量结果小于或等于第二门限值时，对频点的优先级等于或低于第一优先级的小区进行测量，第一优先级为服务小区的频点的优先级。该方案中，也将优先级高于第一优先级的频点也称为高优先级的频点，也将优先级等于或低于第一优先级的频点也称为中低优先级的频点。换句话说，该方案中，对高优先级的频点始终在WUR链路上测量，而对于中低优先级的频点采用上述所描述的通过第一门限值来确定是否进行测量。
可选地，上述所述的第一门限值或第二门限值，可以是单一测量结果的门限，也可以是多个测量结果的门限。但应注意，当是多个测量结果的门限时，需要各个测量结果指标均高于对应门限才认为是高于门限。
应理解，对于上述在WUR链路上定义的测量行为，由于在部分情况下减少了终端设备进行小区测量的次数，因此可以降低终端设备的功耗。
通常，对于终端设备而言，当其在主链路上接收到测量参考信号时可以确定出测量参考信号的频域信息，而当其在WUR链路上接收到测量参考信号时是无法获得测量参考信号的频域信息的，即终端设备无法知道WUR链路上的测量参考信号的带宽和WUR链路的部署带宽的关系，导致在WUR链路上，终端设备只能将整个WUR接收带宽作为测量的频率范围。鉴于此本申请中， 在WUR链路上进行小区测量时，还定义一种新的评价指标，其中，该评价指标可以是如下的一种或多种：
1)测量参考信号在第一时频资源中的测量结果
其中，第一时频资源包括第一时域资源和第一频域资源，第一时域资源为时间区间上接收的测量参考信号所占用的时间单元(即测量参考信号的时间范围)，第一频域资源为测量参考信号的部署带宽(也可以认为是整个WUR接收带宽)。可以看出，该评价指标反映的是针对测量参考信号的测量结果，例如针对测量参考信号的接收功率。
本申请中，将该测量参考信号在第一时频资源中的测量结果也可以称为WUR-RSRP。
2)终端设备在第二时频资源内接收到的总功率。
其中，第二时频资源包括第二时域资源和第二频域资源，第二时域资源包括的时间单元的个数为第一时域资源包括时间单元的个数的K倍，第二频域资源为测量参考信号的部署带宽。具体地，终端设备在第二时频资源内接收到的总功率是指在第二时频资源内接收到的所有信号的总功率，即还包括了服务小区和非服务小区、相邻信道干扰、热噪声等接收功率。
本申请中，将终端设备在在第二时频资源内接收到的总功率也可以称为WUR-RSSI。
为便于理解，图6为本申请提供的一种WUR-RSRP和WUR-RSSI的统计区域的示意图。如图6所示，WUR-RSRP的统计区域和WUR-RSSI的统计区域中，所统计的频域资源均为整个WUR接收带宽，区别在于所统计的时域资源。
3)第一接收质量，第一接收质量为K*第一时频资源中的测量结果/第二时频资源内接收到的总功率。
本申请中，将第一接收质量也称为WUR-RSRQ。
在主链路上，由于接收信号强度指示(received signal strength indicator，RSSI)的测量频率范围和测量参考信号的带宽可以不一样，因此在主链路中的计算参考信号接收质量(reference signal recived quality，RSRQ)的公式中，通过N来做一个缩放。而在WUR链路上，由于无法区分不同的频率范围，因此，本申请中，通过在时域上做设计，将WUR-RSSI的时域测量范围配置为测量参考信号长度的K倍，此时计算WUR-RSRQ时，可以通过K来做缩放。
4)目标误块率，目标误块率为终端设备接收到的唤醒信号校验不通过的比例。
本申请中，将目标误块率也称为WUR-BLER。
由于WUR链路的接收机需要做到低成本低功耗，因此通常可能会采用量化阶次较低的量化器。例如，采用OOK调制时，WUR模块仅需要将接收信号判决为0或者1即可，此时，一个1-bit的量化器即可满足信号解调的需求。但是这种粗糙的量化器可能会导致WUR-RSRQ难以计算。例如，如图7所示，左侧是收到的信号，当采用高精度量化器(量化值的范围是0～9)量化时，信号可以分别被量化为5、2、7、3。而采用低精度量化器时，信号只能被量化为1、0、1、0。
应理解，当量化结果很粗糙时，即使接收的信号功率相差较大，但是在经过量化后取值也可能是相同的。这样，就可能存在计算出来的WUR-RSRQ恒等于1的问题，导致计算出来的WUR-RSRQ不准确的问题。因此，本申请中，还定义了目标误块，其中，目标误块率为终端设备接收到的唤醒信号校验不通过的比例，更具体地，是指终端设备在特定的时频资源内的接收到的唤醒信号校验不通过的比例。可以理解的是，本申请中的WUR-BLER可以反映出信道质量，WUR-BLER越低，说明信道质量越好。
5)第二接收质量，第二接收质量为基于第一映射表确定的与目标误块率具有映射关系的接收质量，第一映射表中包括测量参考信号的接收质量与误块率之间的映射关系。
该方案中，通过定义测量参考信号的接收质量与误块率之间的映射关系，来间接得到第二接收质量。
本实施例中，通过定义新的测量所需要的指标，可以使得终端设备在对每个时间区间上接收到的测量参考信号时，基于上述指标获得不同的测量结果，从而完成测量。
