一种通信方法、装置及设备
相关申请的交叉引用
本申请要求在2022年04月11日提交中国专利局、申请号为202210376458.1、申请名称为“一种通信方法、装置及设备”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
本申请涉及通信领域，尤其涉及一种通信方法、装置及设备。
背景技术
在进行移动性管理时，终端设备可使用同步信号块(synchronization signal block，SSB)进行测量。当在设定时长内某一小区的测量结果均满足设定条件(例如，该小区的信号强度均大于或等于第一阈值)时，终端设备可生成测量报告，并向网络设备发送测量报告。这样，网络设备可根据测量报告对终端设备进行移动性管理，例如，将终端设备切换到其他网络设备中。
目前，移动通信系统(例如，第五代(the 5th generation，5G)移动通信系统)中引入了新型的终端设备，例如降低能力终端(reduced capability UE，RedCap UE)。相对于传统终端设备，新型终端设备支持的带宽范围较窄。例如，RedCap UE可支持20兆赫兹(MHz)带宽(针对频率范围1(frequency range 1，FR1))和100MHz带宽(针对频率范围2(frequency range 2，FR2)。而传统终端设备可支持100MHz带宽(针对FR1)和200MHz带宽(针对FR2)。因此，新型终端设备使用的部分带宽(bandwidth part，BWP)(例如，激活BWP)可能无法包含当前服务区的小区定义的SSB(cell defining SSB，CD-SSB)。这样，新型终端设备可能无法利用CD-SSB进行小区测量。
目前，针对新型终端设备，引入了非小区定义的SSB(Non-cell defining SSB，NCD-SSB)，NCD-SSB可包含在新型终端设备UE使用的BWP(例如，激活BWP)内。新型终端设备可使用NCD-SSB进行小区测量。
终端设备在进行BWP切换时，可能会更换使用的SSB，例如，从使用CD-SSB进行小区测量改为使用NCD-SSB进行小区测量。在切换BWP时，如何进行测量是一个亟需解决的技术问题。
发明内容
本申请提供一种通信方法、装置及设备，用于在切换BWP时进行测量。
第一方面，本申请实施例提供了一种通信方法。该方法包括：
终端设备可使用第一BWP关联的第一SSB进行测量；在接收到第一信息后，终端设备可重置第一测量。其中，第一信息可指示将终端设备的激活BWP切换为第二BWP；第一测量为使用第一SSB的测量。
通过该方法，在切换BWP之后，终端设备可重置使用第一SSB的测量，从而可避免 使用第一SSB的测量对使用第二BWP关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
在一种可能的设计中，第一测量可包括：在测量事件评估中使用第一SSB的测量结果的测量；和/或，在测量报告中上报的使用第一SSB的测量结果的测量。通过该设计，在切换BWP之后，终端设备可重置测量事件评估和/或测量报告中涉及的使用第一SSB的测量结果的测量，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
在一种可能的设计中，终端设备重置第一测量可包括以下至少一项：
C：终端设备重置第一测量的测量事件评估。例如，终端设备在切换BWP时，可重置基于第一SSB进行的测量而启动的评估状态，从而可提高测量事件评估和测量报告的准确性，避免网络设备基于不准确的测量报告进行RRM。
D：终端设备重置第一测量的测量报告上报。例如，终端设备在切换BWP时，可重置使用第一SSB进行小区测量时的上报信息，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量上报，避免网络设备基于不准确的测量报告进行RRM。
在一种可能的设计中，终端设备可通过以下至少一项操作来重置第一测量：
终端设备可删除或清空第一小区列表内的小区；第一小区列表可包括一个或多个小区；该一个或多个小区是第一测量中测量结果满足上报准则的小区；
终端设备可重置或停止第一定时器；第一定时器可用于评估第一测量是否满足上报准则；
终端设备可重置计数器；该计数器可用于指示终端设备发送第一测量的测量报告的次数。
该设计提供了重置第一测量的具体操作，易于实现。
在一种可能的设计中，上述方法还包括：终端设备可使用第二BWP关联的第二SSB进行测量。通过该设计，在切换BWP之后，终端设备可重置使用切换前的第一BWP所关联的第一SSB的测量，并使用第二BWP关联的第二SSB进行测量，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
在一种可能的设计中，第二SSB不同于第一SSB。通过该设计，当切换BWP前后的SSB不同时，在切换BWP之后，终端设备才重置使用切换前的第一BWP所关联的第一SSB的测量，从而保证测量的准确性。
在一种可能的设计中，第一SSB为CD-SSB，第二SSB为NCD-SSB；或者，第一SSB为NCD-SSB，第二SSB为CD-SSB；或者，第一SSB和第二SSB均为CD-SSB；或者，第一SSB和第二SSB均为NCD-SSB。
第二方面，本申请实施例提供了一种通信方法。该方法包括：终端设备可使用第一BWP关联的第一SSB进行测量；在接收到第一信息后，终端设备可停止或挂起第一测量对象关联的测量，和/或，终端设备可将第一测量对象关联的测量关联至第二测量对象。其中，第一信息可指示将终端设备的激活BWP切换为第二BWP；第一测量对象包含第一SSB；第二测量对象包含第二BWP关联的第二SSB。
通过该方法，在切换BWP之后，终端设备可停止或挂起切换前第一BWP所关联的第一SSB的测量，从而可避免进行不必要的第一SSB的测量，进而可实现在切换BWP时进行合理的测量和/或测量上报。
另外，在切换BWP之后，终端设备可将第一测量对象关联的测量关联至第二测量对象，第一测量对象包含第一SSB，第二测量对象包含第二BWP关联的第二SSB。这样，终端设备可以通过与第一测量对象关联的测量，来使用第二SSB进行测量，从而可实现在切换BWP时进行合理的测量和/或测量上报。
在一种可能的设计中，终端设备可将第一测量对象关联的测量上报配置关联至第二测量对象。
通过该设计，在切换BWP之后，终端设备可将第一测量对象关联的测量上报配置关联至第二测量对象，第一测量对象包含第一SSB，第二测量对象包含第二BWP关联的第二SSB。这样，即便第二SSB没有关联的测量上报配置，终端设备也可以通过与第一测量对象关联的测量上报配置，来使用第二SSB进行测量，从而可实现在切换BWP时进行合理的测量和/或测量上报。
并且，通过该设计，针对多个SSB，网络设备只需要发送一套上报配置给终端设备，从而可节约传输资源，节省信令开销。
在一种可能的设计中，第二SSB不同于第一SSB。通过该设计，当切换BWP前后的SSB不同时，在切换BWP之后，终端设备才停止或挂起第一测量对象关联的测量，和/或，将第一测量对象关联的测量关联至第二测量对象，从而保证测量的准确性。
在一种可能的设计中，第一SSB为CD-SSB，第二SSB为NCD-SSB；或者，第一SSB为NCD-SSB，第二SSB为CD-SSB；或者，第一SSB和第二SSB均为CD-SSB；或者，第一SSB和第二SSB均为NCD-SSB。

具体实施方式
本申请提供一种通信方法及设备，用以在切换BWP时进行测量。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。
在本申请实施例提供的方案中，终端设备可使用第一BWP关联的第一SSB进行测量；在接收到第一信息后，终端设备可重置第一测量。其中，第一信息可指示将终端设备的激活BWP切换为第二BWP；第一测量为使用第一SSB的测量。这样，在切换BWP之后，终端设备重置使用第一SSB的测量，从而可避免使用第一SSB的测量对使用第二BWP关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
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)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal，MT)、无线通信设备、终端代理或终端设备等。
例如，终端设备可以为具有无线连接功能的手持式设备，也可以是具有通信功能的车辆，车载设备(如车载通信装置，车载通信芯片)等。目前，一些终端设备的举例为：手机(mobile phone)、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、平板电脑、带无线收发功能的电脑、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，是移动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，还可以称为基站、无线接入网(radio access network，RAN)节点(或设备)、接入点(access point，AP)、接入网(access network，AN)设备。
目前，一些网络设备的举例为：新一代节点B(generation Node B，gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、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)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心、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，所述网络设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)。这种结构将网络设备的协议层拆分开，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。例如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)层和分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，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。
可选的，网络设备还可以包括有源天线单元(active antenna unit，AAU)。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY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+AAU发送的。
可以理解的是，网络设备可以为包括CU、DU、AAU中一项或多项。此外，可以将CU划分为接入网中的网络设备，也可以将CU划分为CN中的网络设备，本申请对此不做限定。
3)、在本申请中，基于NCD-SSB的测量结果可以替换为基于NCD-SSB频点的测量结果。SSB频点可以替换为SSB频率。测量事件评估可以替换为测量评估。测量报告上报可以替换为测量上报。基于SSB评估的测量报告可以替换为基于SSB的测量结果的测量报告。
本申请实施例中，对于名词的数目，除非特别说明，表示“单数名词或复数名词”，即“一个或多个”。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“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。“以下至少一项(个)”或其类似表达，是指这些项(个)中的任意组合，包括单项(个)或复数项(个)的任意组合。
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，而不应理解为指示或暗示相对重要性，也不应理解为指示或暗示顺序。
下面将结合附图，对本申请实施例应用的通信系统进行描述。
图1示出了本申请实施例提供的方法适用的移动通信系统的结构。参阅图1所示，在该系统中包括：网络设备和终端设备(例如图1中所示的终端设备a、终端设备b)。
所述网络设备，是网络侧能够接收和发射无线信号的实体，负责为处于其覆盖范围内的终端设备提供无线接入有关的服务，实现物理层功能、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功能。
所述终端设备，为用户侧能够接收和发射无线信号的实体，需要通过所述网络设备接入网络。所述终端设备可以为各种为用户提供语音和/或数据连通性的设备，例如图1所示，所述终端设备可以为车载设备、智能手机等。
其中，所述终端设备可以与一个网络设备建立连接，形成单连接通信系统；也可以与两个网络设备建立连接，形成双连接(dual connectivity，DC)通信系统。
还需要指出的是，如图1所示的移动通信系统作为一个示例，并不对本申请实施例提供的方法适用的通信系统构成限定。总之，本申请实施例提供的方法，适用于各种终端设备支持多发能力的通信系统和应用场景中，即本申请实施例还可以应用于各种类型和制式的通信系统，例如：5G通信系统、长期演进(Long Term Evolution，LTE)通信系统、无线保真(wireless fidelity，Wi-Fi)系统、6G通信系统以及未来通信系统、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)，本申请实施例不予限定。
下面介绍本申请相关的背景技术。
1、RedCapUE：
与增强移动宽带(enhanced Mobile Broadband，eMBB)和超可靠低时延通信(Ultra-Reliable and Low Latency Communication，URLLC终端设备相比，RedCap UE是降低能力的终端。例如，与eMBB和URLLC的终端设备相比，RedCap UE可能进行以下特性复杂度的降低：降低最大带宽能力、降低收发天线数目/天线通道(branch)数目、降低最大多进多出(multiple input multiple outpout，MIMO)层数能力、降低最大调制阶数(modulation order)能力、支持半双工频分双工(frequency division duplexing，FDD)(Half Duplex FDD，HD-FDD)等。
第三代合作伙伴计划(3rd generation partnership project，3GPP)版本17(release 17，R17)标准定义的RedCap UE的最大带宽能力为：20MHz带宽(针对FR1)，100MHz带宽(针对FR2)。而eMBB和URLLC的终端设备(也可以称为非RedCap的终端设备)的最大带宽能力可以为：100MHz带宽(针对FR1)，200MHz带宽(针对FR2)。
2、SSB，可用于终端设备进行定时同步和测量等操作。SSB可包括CD-SSB和NCD-SSB。
其中，CD-SSB是与系统信息块1(system information block 1，SIB1)相关联的SSB。终端设备可基于CD-SSB获取SIB1，进行如下操作至少一项：定时同步、进行无线链路监测(radio link monitoring，RLM)/波束失败检测(beam failure detection，BFD)/无线资源管理(radio resource management，RRM)测量和波束管理等。
NCD-SSB为缺少建立一个完整小区的信息的SSB。例如，NCD-SSB仅包含同步信号； 又例如，NCD-SSB未与SIB1相关联；再例如，与目前的SIB1相比，NCD-SSB关联的SIB1缺少部分字段。
另外，NCD-SSB可以是为新型终端设备(例如，RedCap UE)额外配置的SSB。由于RedCap UE最大带宽能力的限制，RedCap UE使用的BWP(例如，激活BWP)可能不包含当前服务区的CD-SSB。这种情况下，RedCap UE可能无法利用CD-SSB进行定时同步和测量等操作。因此，目前提供了NCD-SSB，NCD-SSB可包含在RedCap UE使用的BWP(例如，激活BWP)内，并可替代CD-SSB的功能。
如前所述，终端设备可根据SSB进行测量；这样，网络设备可根据UE根据SSB的RRM测量进行移动性控制(系统内或系统问的切换或重定向)或载波聚合/双连接建立。下面参考图2，以终端设备为UE为例，说明对终端设备根据SSB进行测量。
S201：网络设备向UE发送测量配置信息。
其中，测量配置信息中可包含以下至少一项测量配置参数：测量对象(MeasObj)、上报配置(ReportConfig)、测量标识(MeasId)等。
测量对象用于指示UE执行测量的对象。其中，测量对象可关联一个测量对象标识。测量对象中可包括以下至少一项：参考信号配置信息、以及小区相关信息等。新无线(new radio，NR)中的参考信号包括：SSB与信道状态信息参考信号(channel state information-reference signal，CSI-RS)。例如，如果网络设备配置UE基于SSB参考信号进行测量，则测量对象中可包含SSB的配置信息。
上报配置用于配置测量上报的规则和测量报告的格式。其中，上报配置可关联一个上报标识。上报配置中可包括以下至少一项：上报准则、上报周期、上报的测量报告的总数、上报的最大小区数、上报的测量结果的参考信号类型等。
其中，上报准则是触发UE进行测量上报(即触发UE发送测量报告)的准则；上报准则的类型可包括周期型和/或事件触发型等。周期型的上报准则为按照设定周期上报测量报告；UE可通过周期上报定时器进行周期性测量报告的上报，该周期上报定时器的定时时长为该设定周期。事件触发型的上报准则可以包括A类事件和/或B类事件。其中，A类事件为同无线接入技术(intra-radio accesss technology，intra-RAT)的事件，例如，A1事件、A2事件、A3事件和A5事件等中的至少一项。B类事件为异RAT(irnter-RAT)的事件，例如，B2事件。其中，上述任一事件的具体内容可参考对图5的说明，此处暂不展开。
测量标识可用于关联一个测量对象和一个上报配置；这样，一个测量标识可标识一个测量。UE可在上报的测量报告中包含相应的测量标识，以便网络设备确定该测量报告是哪个测量的结果。
另外，测量配置信息可承载于RRC消息中，例如，RRC重配置消息(RRCReconfigration)中。
S202：UE根据测量配置信息进行测量，并在满足上报准则时，向网络设备发送测量报告。
具体的，UE可根据测量配置信息，使用当前激活BWP关联的SSB进行服务区和/或邻区的测量，并对测量结果进行评估；当评估服务区和/或邻区满足上报准则时，UE可生成对应的测量报告，并向网络设备发送测量报告。
其中，事件触发型的上报准则可包括：在第一时长内测量结果持续满足事件的进入条件。可选的，第一时长可由网络配置的触发时间参数(timeToTrigger)来确定，换句话说，网络配置评估定时器的定时时长为第一时长。第一时长可包含在上报配置中。例如，当基于当前激活BWP关联的SSB检测到第一小区的测量结果满足事件的进入条件时，UE可启动该评估定时器。如果在评估定时器运行期间第一小区的测量结果均满足事件的进入条件，则在评估定时器超时后，UE向网络设备发送测量报告；和/或，如果在评估定时器运行期间该第一小区的测量结果不满足事件的进入条件，停止或重置该评估定时器。其中，第一小区为服务区和/或邻区中的任一小区。
另外，UE最多可上报N次测量报告。其中，N为正整数，可由网络设备来配置；例如，N为上报配置中的上报的测量报告的总数。
S203：网络设备根据来自UE的测量报告确定RRM操作。
例如，RRM操作可以为对UE执行切换；示例性的，可以为将UE切换到另一个网络设备(即目标网络设备)。又例如，RRM操作可以为：为UE添加辅小区或建立双连接。
目前，一个小区可能包括多个SSB(例如，CD-SSB和NCD-SSB)，UE在切换激活BWP(简称切换BWP)时，也可能会切换测量所使用的SSB。采用图2所示的方法进行测量时，在切换BWP后UE如何进行测量(例如，如何进行测量事件评估和/或测量报告上报)是需要解决的问题。具体的，UE通过图2所示的方法进行测量时，可能会存在如下问题：
1、如图3A所示，切换BWP时，UE正在基于切换BWP前的SSB进行测量评估。具体的，在T1时刻，UE基于BWP1关联的CD-SSB进行的小区测量满足事件的进入条件，从而启动评估定时器；在T2时刻，UE的激活BWP从BWP1切换到BWP2，并基于与BWP2关联的NCD-SSB对小区进行测量；在T2时刻，基于BWP1关联的CD-SSB的测量结果启动的评估定时器尚未超时，换句话说，基于CD-SSB进行的测量启动的评估状态正在进行；在T3时刻，UE得到BWP2关联的NCD-SSB的测量结果。在T2时刻之后，如何处理该评估状态，是需要解决的问题。
2、如图3B所示，切换BWP时，UE已完成基于切换BWP前的SSB的测量评估。具体的，在T4时刻，UE基于BWP1关联的CD-SSB进行的小区测量满足事件的进入条件，从而启动评估定时器；在T5时刻，评估定时器超时，UE触发向网络设备发送测量报告；在T6时刻，UE的激活BWP从BWP1切换到BWP2，并基于与BWP2关联的NCD-SSB对小区进行测量；在T7时刻，UE得到BWP2关联的NCD-SSB的测量结果。在T6时刻之后，如何处理基于CD-SSB进行的测量上报，是需要解决的问题，例如，是否要继续使用基于CD-SSB进行测量时的上报信息(例如，已上报测量报告的次数、上报小区列表)。
3、在一些场景中，测量对象有关联上报配置。例如，服务区包含CD-SSB和NCD-SSB；测量对象1包含CD-SSB，测量对象2包含NCD-SSB；测量对象1和测量对象2分别有关联上报配置。
在另一些场景中，仅部分测量对象有关联上报配置。例如，服务区包含CD-SSB和NCD-SSB；测量对象1包含CD-SSB，测量对象2包含NCD-SSB；测量对象1有关联上报配置，而测量对象2未关联上报配置。
在BWP切换时，如果测量使用的SSB也发生切换(例如，从CD-SSB切换到NCD-SSB)，UE应该如何进行测量是需要解决的问题。
下面结合附图对本申请提供的方案进行说明。
本申请实施例提供了一种通信方法，该方法可解决上述问题1和问题2。该方法可应用于图1所示的通信系统中。下面参阅图4所示的流程图，对该方法的流程进行具体说明。
S401：终端设备使用第一BWP关联的第一SSB进行测量。
其中，第一BWP可为终端设备当前的激活BWP。第一SSB可在第一BWP带宽范围内，也可不在第一BWP带宽范围内。
终端设备可使用第一BWP关联的第一SSB对终端设备的服务区和/或邻区进行测量。具体内容可参考S202，此处不再赘述。
S402：终端设备接收第一信息。第一信息可指示将终端设备的激活BWP切换为第二BWP。
其中，终端设备可接收来自网络设备的第一信息。第一信息可承载在现有的信令(例如，无线资源控制(radio resource control，RRC)重配置消息、下行控制信息(Downlink Control Information，DCI)等)中，也可承载在新的信令中。
S403：终端设备重置第一测量。其中，第一测量可为使用第一SSB的测量。
在一些可能的方式中，第一测量可为直接与第一SSB相关联的测量。具体地，第一测量对象包含第一SSB，第一测量与第一测量对象相关联。例如，终端设备对第一SSB进行测量获得服务区和/或邻区的测量结果(如，服务区和/或邻区的参考信号质量)，使用服务区和/或邻区的测量结果评估是否满足上报准则，和/或进行测量上报。
在另一些可能的方式中，第一测量可为使用第一SSB的测量结果的测量。例如，第一测量与第二测量对象相关联，第二测量对象包含第三SSB，终端设备对第三SSB进行测量获得邻区1的测量结果(如，邻区1的参考信号质量)；终端设备对第一SSB进行测量获得服务区的测量结果(如，服务区的参考信号质量)。终端设备可确定邻区1的参考信号质量是否高于服务区的参考信号质量，从而确定是否要上报测量报告。此时，第一测量为使用第一SSB的测量结果的测量，具体的，为使用第一SSB的测量结果和使用第三SSB的测量结果的测量。
在本申请中，信号质量可为信号强度。用于体现或表示信号强度的参数可以包括以下至少一项：参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)和接收的信号强度指示(received signal strength indication，RSSI)。
通过该方法，在切换BWP之后，终端设备可重置使用切换前的第一BWP所关联的第一SSB的测量，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
可选的，在本申请实施例的一些可能的实现方式中，第一测量可包括以下至少一项：
A：在测量事件评估中使用第一SSB的测量结果的测量。其中，第一SSB的测量结果可以为对第一SSB进行测量而获得的至少一个小区的测量结果。其中，至少一个小区可包括服务区和/或邻区。
B：在测量报告中上报的使用第一SSB的测量结果的测量；换句话说，是将第一SSB的测量结果包含在测量报告中的测量。第一SSB的测量结果的具体内容可参考A，此处不再赘述。
通过该方法，在切换BWP之后，终端设备可重置测量事件评估和/或测量报告中涉及的使用第一SSB的测量结果的测量，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
可选的，在本申请实施例的一些可能的实现方式中，S403可包括以下至少一项：
C：终端设备重置第一测量的测量事件评估。
例如，在BWP切换前，终端设备根据使用第一SSB(例如CD-SSB)进行的测量来启动评估定时器(即启动了评估状态，具体内容可参考问题1)；当接收到用于切换激活BWP的第一信息时，该评估定时器未超时，即基于切换前BWP关联的SSB进行的小区测量启动的评估状态正在进行；此时，终端设备可重置该正在进行的评估状态。
通过该方法，终端设备在切换BWP时，可重置基于第一SSB进行的测量而启动的评估状态(即解决问题1)，从而可提高测量事件评估和测量报告的准确性，避免网络设备基于不准确的测量报告进行RRM。
D：终端设备重置第一测量的测量报告上报。
例如，在BWP切换前，终端设备根据使用第一SSB(例如CD-SSB)进行的测量上报测量报告(具体内容可参考问题2)；当接收到用于切换激活BWP的第一信息时，终端设备可重置使用第一SSB进行测量时的上报信息。
通过该方法，终端设备在切换BWP时，可重置使用第一SSB进行小区测量时的上报信息(即解决问题2)，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量上报，避免网络设备基于不准确的测量报告进行RRM。
可选的，在本申请实施例的一些可能的实现方式中，在S403中，终端设备可通过以下至少一项操作，来重置第一测量：
E：终端设备删除或清空第一小区列表内的小区。
其中，第一小区列表可包括一个或多个小区；一个或多个小区是第一测量中测量结果满足上报准则的小区。上报准则的具体内容可参考S201和S202，重复之处不再赘述。此外，上报准则可为终端设备向网络设备发送测量报告时应满足的条件或要求，换句话说，上报准则可触发终端设备发送测量报告。
F：终端设备删除第一小区列表。其中，第一小区列表的具体内容可参考E，此处不再赘述。
G：终端设备重置或停止第一定时器。
其中，重置第一定时器可为将第一定时器的定时设置为初始值。其中，第一定时器的初始值可为第一定时器的定时时长。第一定时器的定时时长可为预先设定的，也可以为其他通信设备(例如，网络设备)通知给终端设备的。
可选的，第一定时器用于评估第一测量是否满足上报准则，例如，第一定时器为S202中的评估定时器。
另外，第一定时器的定时时长可为第一测量持续满足上报准则的时长，例如，S202中的第一时长。
H：终端设备重置计数器。
其中，计数器可用于指示终端设备发送第一测量的测量报告的次数。例如，计数器的初始值为0，终端设备每发送一次测量报告，就将计数器加1。
另外，计数器的初始值可为0，也可以为其他设定值。计数器的初始值可为预先设定的，也可以为其他通信设备(例如，网络设备)通知给终端设备的。每次发送测量报告时，终端设备可将计数器加1，也可以加其他设定值；换句话说，计数器的累加值可为1，也可以为其他设定值。
如前所述，终端设备最多可发送N次测量报告。通过重置计数器，在切换BWP之后，终端设备可重新对测量报告的发送次数进行计数，从而避免因第一测量的测量报告的次数达到N次而无法针对第二SSB的测量结果上报测量报告，进而可避免对网络设备的误导。
I：停止、暂停或重置周期上报定时器(例如，S201中的周期上报定时器)。
其中，重置周期上报定时器可为将周期上报定时器的定时设置为初始值。其中，周期上报定时器的初始值可为周期上报定时器的定时时长。周期上报定时器的定时时长可为网络设备通知给终端设备的。
可选的，当终端设备重置第一测量的测量事件评估时，终端设备可执行E、F和G中的至少一项；和/或，当终端设备重置第一测量的测量报告上报时，终端设备可执行E、F、H和I中的至少一项。
该方法提供了重置第一测量的具体操作，易于实现。
可选的，在本申请实施例的一些可能的实现方式中，该方法还包括：
S404：终端设备使用第二BWP关联的第二SSB进行测量。
其中，第二SSB可在第二BWP带宽范围内，也可不在第二BWP带宽范围内。
此外，S404的具体内容可参考S202，此处不再赘述。
另外，S404可在S402之后执行，也可在S403之后执行。
通过该方法，在切换BWP之后，终端设备可重置使用切换前的第一BWP所关联的第一SSB的测量，并使用第二BWP关联的第二SSB进行测量，从而可避免使用第一SSB的测量对使用切换后的第二BWP所关联的第二SSB测量的影响，进而可实现在切换BWP时进行合理的测量和/或测量上报。
可选的，在本申请实施例的一些可能的实现方式中，第二SSB不同于第一SSB。
在一些可能的方式中，第一SSB的频点可以不同于第二SSB的频点，和/或，第一SSB的子载波间隔(sub-carrier space)可以不同于第二SSB的子载波间隔。其中，SSB的频点可为SSB的中心频点，也可以为与中心频点偏移第一值的频点。其中，第一值可为正数，可为负数，也可以为0。第一值可以是预先设定的，也可以是其他通信设备(例如，网络设备)通知终端设备的。此时，第一SSB和第二SSB可以均为CD-SSB，也可以均为NCD-SSB。
在另一些可能的方式中，第一SSB的类型不同于第二SSB的类型。例如，第一SSB为CD-SSB，第二SSB为NCD-SSB；或者，第一SSB为NCD-SSB，第二SSB为CD-SSB。
另外，第二SSB不同于第一SSB可为步骤S403的条件，也就是说，当第二SSB不同于第一SSB，终端设备重置第一测量。
通过该方法，当切换BWP前后的SSB不同时，在切换BWP之后，终端设备才重置使用切换前的第一BWP所关联的第一SSB的测量，从而保证测量的准确性。
本申请实施例提供了一种通信方法，该方法可解决上述问题3。该方法可应用于图1所示的通信系统中。下面参阅图5所示的流程图，对该方法的流程进行具体说明。
S501：终端设备使用第一BWP关联的第一SSB进行测量。
S502：终端设备接收第一信息；第一信息可指示将终端设备的激活BWP切换为第二BWP。
S501-S502的具体内容可参考S401-S402，此处不再赘述。
S503：终端设备停止或挂起(也可称为暂停)第一测量对象关联的测量，第一测量对象包含第一SSB；和/或，终端设备将第一测量对象关联的测量关联至第二测量对象，第二测量对象包含第二BWP关联的第二SSB。
其中，终端设备停止或挂起(也可称为暂停)第一测量对象关联的测量的具体内容可参考S804；此处暂不展开。
通过该方法，在切换BWP之后，终端设备可停止或挂起切换前第一BWP所关联的第一SSB的测量，从而可避免进行不必要的第一SSB的测量，进而可实现在切换BWP时进行合理的测量和/或测量上报。
另外，在切换BWP之后，终端设备可将第一测量对象关联的测量关联至第二测量对象，第一测量对象包含第一SSB，第二测量对象包含第二BWP关联的第二SSB。这样，终端设备可以通过与第一测量对象关联的测量，来使用第二SSB进行测量，从而可实现在切换BWP时进行合理的测量和/或测量上报。
可选的，在本申请实施例的一些可能的实现方式中，S503中的“将第一测量对象关联的测量关联至第二测量对象”可包括：
终端设备将第一测量对象关联的测量上报配置关联至第二测量对象。其中，该测量上报配置可为S201中的上报配置。
通过该方法，在切换BWP之后，终端设备可将第一测量对象关联的测量上报配置关联至第二测量对象，第一测量对象包含第一SSB，第二测量对象包含第二BWP关联的第二SSB。这样，即便第二SSB没有关联的测量上报配置，终端设备也可以通过与第一测量对象关联的测量上报配置，来使用第二SSB进行测量，从而可实现在切换BWP时进行合理的测量和/或测量上报(即解决上述问题3)。
并且，通过该方法，针对多个SSB，网络设备只需要发送一套上报配置给终端设备，从而可节约传输资源，节省信令开销。
可选的，在本申请实施例的一些可能的实现方式中，第一测量对象关联的测量包含以下至少一项：
A1事件，A2事件，A3事件，A5事件，B2事件。
换句话说，第一测量对象关联的测量上报配置可以是以下至少一项：A1事件，A2事件，A3事件，A5事件，B2事件。
其中，A1事件的进入条件为：服务区的信号质量高于第二阈值。
A2事件的进入条件为：服务区的信号质量低于第三阈值。
A3事件的进入条件为：邻区的信号质量与服务区的信号质量之差大于第四阈值；换句话说，邻区的信号质量比服务区的信号质量高出一定偏移量，该偏移量为第四阈值。其中，服务区可以为特殊小区(Special Cell，SpCell)，即主小区(Primary Cell，PCell)和/或主辅小区(Primary Secondary Cell，PSCell)。
A5事件的进入条件为：服务区的信号质量低于第五阈值，且邻区的信号质量高于第六阈值。其中，服务区可以为SpCell，即PCell和/或PSCell。
B2事件的进入条件为：服务区的信号质量低于第七阈值，且inter-RAT邻区的信号质量高于第八阈值。其中，服务区可以为PCell。
可选的，上述任一事件的进入条件中，信号质量可为参考信号质量。另外，信号质量可为信号强度。用于体现或表示信号强度的参数可以包括以下至少一项：RSRP、RSRQ和RSSI。
可选的，在本申请实施例的一些可能的实现方式中，第二SSB不同于第一SSB。
在一些可能的方式中，第一SSB的频点可以不同于第二SSB的频点，和/或，第一SSB的子载波间隔可以不同于第二SSB的子载波间隔。其中，SSB的频点可为SSB的中心频点，也可以为与中心频点偏移第一值的频点。其中，第一值可为正数，可为负数，也可以为0。第一值可以是预先设定的，也可以是其他设备(例如，网络设备)通知终端设备的。此时，第一SSB和第二SSB可以均为CD-SSB，也可以均为NCD-SSB。
在另一些可能的方式中，第一SSB的类型不同于第二SSB的类型。例如，第一SSB为CD-SSB，第二SSB为NCD-SSB；或者，第一SSB为NCD-SSB，第二SSB为CD-SSB。
另外，第二SSB不同于第一SSB可为步骤S503的条件，也就是说，当第二SSB不同于第一SSB，终端设备执行S503。
通过该方法，当切换BWP前后的SSB不同时，在切换BWP之后，终端设备才执行S503，从而保证测量的准确性。
本申请实施例提供了一种通信方法，该方法为图4所示方法的一种可能的实现方式，可用于解决上述问题1。该方法可应用于图1所示的通信系统中。下面参阅图6所示的流程图，以第一SSB为CD-SSB，第二SSB为NCD-SSB，终端设备为UE为例，对该方法的流程进行具体说明。
S601：网络设备向UE发送RRC重配置消息(RRCReconfigration)。
其中，RRC重配置消息中包含测量配置信息，测量配置信息指示的配置内容可包含：CD-SSB测量配置和/或NCD-SSB测量配置。测量配置信息的具体内容可参考S201中的测量配置参数，此处不再赘述。
S602：UE保存来自网络设备的测量配置信息，并向网络设备发送RRC重配置完成消息(RRCReconfigrationComplete)。
S603：UE当前的激活BWP(例如，S401中的第一BWP)关联CD-SSB，UE基于CD-SSB(也可以称为基于CD-SSB频点)进行测量和/或测量事件评估。
S604：基于CD-SSB频点的测量结果，UE确定小区(例如，服务区或邻区)的测量结果满足测量配置信息中配置的测量事件(例如，满足测量配置信息中的上报准则包含的 事件的进入条件)，启动定时器T8。
其中，该定时器T8可为S202中的评估定时器和/或S403中的第一定时器。该定时器T8的定时时长可为S403中的第一时长。T8的定时时长可为网络设备配置的。
另外，S604的具体内容可参考S202，此处不再赘述。
S605：网络设备向UE发送DCI。
其中，该DCI可包含第一信息，第一信息用于指示BWP切换。切换后的激活BWP(例如，S402中的第二BWP)关联NCD-SSB。第一信息的具体内容可参考S402，此处不再赘述。
S606：UE的激活BWP切换到第二BWP后，UE可重置当前基于CD-SSB测量结果的评估状态。
可选的，UE可执行以下操作至少一项：
停止或重启正在运行的定时器；
删除第一小区列表；
删除或清空第一小区列表中的小区；
删除小区历史测量结果。
S606的具体内容可参考S403，此处不再赘述。
S607：UE使用切换后的激活BWP(例如，S404中的第二BWP)关联的NCD-SSB进行测量，并进行测量事件评估。
S608：基于NCD-SSB的测量结果，UE确定小区(服务区或邻区)的测量结果满足测量配置信息中配置的测量事件(例如，满足测量配置信息中的上报准则包含的事件的进入条件)，启动定时器T9。
其中，T9的定时时长可为网络设备配置的。
S608的具体内容可参考S202，此处不再赘述。
S609：在定时器T9运行期间，UE确定小区的测量结果均满足测量配置信息中配置的测量事件。定时器T9超时，UE向网络设备发送测量报告(MeasuremetReport)，该测量报告为基于NCD-SSB评估的测量报告。
在该方法中，同一小区同时配置CD-SSB和NCD-SSB测量时，若BWP切换前后的激活BWP关联不同的SSB，UE基于切换前的SSB评估的状态可能正在进行(例如，评估定时器正在运行)，UE可重置正在进行的评估状态，并基于当前激活BWP关联的SSB重新执行测量事件评估和测量报告上报。这样，当因BWP切换而使用新的SSB时，UE可以及时停止正在进行的基于切换前SSB评估结果的评估状态，从而增加了UE的可执行性(换句话说，UE易于实现该方法)，避免了UE向网络设备发送基于切换前SSB的测量报告，进而避免对网络设备的误导。
本申请实施例提供了一种通信方法，该方法为图4所示方法的另一种可能的实现方式，可用于解决上述问题2。该方法可应用于图1所示的通信系统中。下面参阅图7所示的流程图，以第一SSB为CD-SSB，第二SSB为NCD-SSB，终端设备为UE为例，对该方法的流程进行具体说明。
S701：网络设备向UE发送RRC重配置消息(RRCReconfigration)。
S702：UE保存来自网络设备的测量配置信息，并向网络设备发送RRC重配置完成消 息(RRCReconfigrationComplete)。
S703：UE当前的激活BWP(例如，S401中的第一BWP)关联CD-SSB，UE基于CD-SSB(也可以称为基于CD-SSB频点)进行测量和测量事件评估。
S704：基于CD-SSB频点的测量结果，UE确定小区(例如，服务区或邻区)的测量结果满足测量配置信息中配置的测量事件(例如，满足测量配置信息中的上报准则包含的事件的进入条件)，启动定时器T8。
S701-S704的具体内容可参考S601-S604，此处不再赘述。
S705：在定时器T8运行期间，UE确定小区的测量结果均满足测量配置信息中配置的测量事件。定时器T8超时，UE向网络设备发送第一测量报告(MeasuremetReport)，该第一测量报告为基于CD-SSB评估的测量报告。
另外，UE可更新维护的上报小区列表(即S403中的第一小区列表)，并将上报测量报告的计数加1(例如，将S403中的计数器加1)。
S706：网络设备向UE发送DCI。
其中，该DCI可包含第一信息，第一信息用于触发BWP切换。切换后的激活BWP(例如，S402中的第二BWP)关联NCD-SSB。第一信息的具体内容可参考S402，此处不再赘述。
S707：UE的BWP切换到第二BWP后，UE可重置基于CD-SSB的测量结果的历史上报信息。
可选的，UE可执行以下操作至少一项：
删除第一小区列表；
删除或清空第一小区列表中的小区；
删除已上报测量报告的次数；例如，重置计数器，该计数器用于指示UE发送基于CD-SSB的测量结果的测量报告的次数。
停止、暂停或重置正在运行的周期上报定时器。
S707的具体内容可参考对S403的说明，此处不再赘述。
S708：UE使用切换后的激活BWP(例如，S404中的第二BWP)关联的NCD-SSB进行测量，并重新进行测量事件评估。
S709：基于NCD-SSB频点的测量结果，UE确定小区(服务区或邻区)的测量结果满足测量配置信息中配置的测量事件(例如，满足测量配置信息中的上报准则包含的事件的进入条件)，启动定时器T9。
其中，T9的定时时长可为网络设备配置的。
S709的具体内容可参考S202，此处不再赘述。
S710：在定时器T9运行期间，UE确定小区的测量结果均满足测量配置信息中配置的测量事件。定时器T9超时，UE向网络设备发送第二测量报告(MeasuremetReport)，该第二测量报告为基于NCD-SSB评估的测量报告。
在该方法中，同一小区同时配置CD-SSB和NCD-SSB测量时，若BWP切换前后激活BWP关联不同的SSB，UE可重置基于切换前的SSB评估的历史上报信息。这样，当因BWP切换而使用新的SSB时，UE可以及时清除基于切换前SSB频点的历史上报信息，避免历史上报信息的残留影响新的SSB测量事件的上报，从而保证切换到新的SSB后可以触发上报新的测量报告。
本申请实施例提供了一种通信方法，该方法为图5所示方法的一种可能的实现方式，可用于解决上述问题3。该方法可应用于图1所示的通信系统中。下面参阅图8所示的流程图，以第一SSB为CD-SSB，第二SSB为NCD-SSB，终端设备为UE为例，对该方法的流程进行具体说明。
S801：网络设备向UE发送RRC重配置消息(RRCReconfigration)。
其中，RRC重配置消息中包含测量配置信息，测量配置信息指示的配置内容可包含：CD-SSB测量配置和/或NCD-SSB测量配置。
在一些可能的场景(下面称为场景1)中，对于小区1(例如，服务区)，测量配置信息可指示如下信息：测量对象1包含CD-SSB，测量对象1关联的上报配置(ReportConfig)为第一上报配置，测量对象1关联的测量标识为MeasId1；测量对象2包含NCD-SSB，测量对象2关联的上报配置(ReportConfig)为第二上报配置，测量对象2关联的测量标识为MeasId2。换句话说，对于小区1的基于CD-SSB和NCD-SSB的测量，网络设备将这两个测量都关联了上报配置，关联关系可参见图9A。其中，第一上报配置和第二上报配置可以相同，也可以不同。
在另一些可能的场景(下面称为场景2)中，对于小区1(例如，服务区)，测量配置信息可指示如下信息：测量对象1包含CD-SSB，测量对象1关联的上报配置(ReportConfig)为第一上报配置，测量对象1关联的测量标识为MeasId1；测量对象2包含NCD-SSB测量，测量对象2未关联上报配置和测量标识。换句话说，对于小区1的基于CD-SSB和NCD-SSB的测量，网络设备只针对CD-SSB关联了上报配置，关联关系可参见图9B的上图。
S802：UE当前的激活BWP(例如，S501中的第一BWP)关联CD-SSB，UE基于CD-SSB(也可以称为基于CD-SSB频点)进行测量和测量事件评估。
S803：网络设备向UE发送DCI。
其中，该DCI可包含第一信息，第一信息可用于触发BWP切换。切换后的激活BWP(例如，S503中的第二BWP)关联NCD-SSB。
S802-S803的具体内容可参考S501-S502，此处不再赘述。
S804：UE停止或挂起(也可称为暂停)第一测量对象关联的测量，第一测量对象包含CD-SSB；和/或，终端设备将第一测量对象关联的测量关联至第二测量对象，第二测量对象包含第二BWP关联的NCD-SSB。
下面分别针对场景1和场景2，对S804进行说明。
对于场景1：
切换BWP后的NCD-SSB频点所对应的测量对象(MeasObj)2关联了上报配置(ReportConfig)和测量标识(MeasId)，UE可使用测量对象2关联的ReportConfig(即第二上报配置)和MeasId(即MeasId2)进行测量事件评估，和/或进行测量报告上报。同时，UE可停止或忽略切换前CD-SSB频点对应的测量对象1的测量，例如，不使用测量对象1关联的ReportConfig(即第一上报配置)和MeasId(即MeasId1)进行测量事件评估，和/或进行测量报告上报。
对于场景2：
切换BWP后的NCD-SSB频点对应的测量对象(MeasObj)2未关联上报配置(ReportConfig)和测量标识(MeasId)，UE可将测量对象2与切换BWP前的ReportConfig(即第一上报配置)和测量标识(即MeasId1)关联(关联关系可参见图9B的下图)，并 基于调整后的关联关系进行测量事件评估，和/或进行测量报告上报。同时，UE可停止或忽略使用切换BWP前的CD-SSB频点对应的测量对象1进行测量事件评估和测量报告上报。
在场景2中，示出了UE调整MeasObj与ReportConfig和测量标识之间关联关系的示例。另外，MeasObj与ReportConfig和测量标识之间关联关系的调整也可以是基于网络设备配置的。例如，在网络设备通知UE切换BWP之后或者网络设备通知UE切换BWP时，网络设备可向UE发送用于指示调整后的关联关系的信息；UE基于该信息获取调整后的关联关系，并基于调整后的关联关系进行测量事件评估，和/或进行测量报告上报。
在该方法中，UE可基于所在当前激活BWP关联的SSB进行服务区的测量事件评估和测量报告上报，而忽略或停止基于切换BWP前的SSB测量而进行的服务区的测量事件评估和测量报告上报，从而明确了UE对服务区的测量事件评估和测量报告上报的行为，增强了UE的可执行性。
另外，在切换BWP之后，UE可忽略或停止基于切换前的SSB测量而进行的服务区的测量事件评估和测量报告上报，从而可避免进行不必要的第一SSB的测量，即避免UE的冗余评估和上报行为，提高测量事件评估和测量报告上报的准确性，进而可避免对网络设备的误导。
此外，在切换BWP之后，UE可将切换前SSB关联的测量关联至切换后的SSB。这样，即便切换后的SSB没有关联测量配置，UE也可以通过与切换前SSB关联的测量，来使用切换后的SSB进行测量，从而可实现在切换BWP时进行合理的测量和/或测量上报。
