相关申请的交叉引用
本申请要求在2022年03月04日提交中国专利局、申请号为202210211027.X、申请名称为“一种通信方法及装置”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，尤其涉及一种通信方法及装置。
背景技术
目前，在新无线系统中，空闲状态的终端设备可以基于同步信号块(synchronization signal block,SSB)进行小区重选。终端设备基于SSB进行小区重选时是基于小区定义的同步信号/物理广播信道块(cell defining synchronization signal block，CD-SSB)的。但是终端设备的初始带宽部分(bandwidth part，BWP)上可能不存在CD-SSB，导致终端设备无法正常进行小区重选，进而导致通信中断，或者通信质量差等问题。
因此，如何提升终端设备的通信性能成为亟待解决的技术问题。
发明内容
本申请提供一种通信方法及装置，用于提高终端设备的通信性能。
第一方面，本申请提供一种通信方法，该方法的执行主体可以是终端设备，也可以是终端设备中的芯片或电路。以终端设备为例，该终端设备在空闲态或者非激活态驻留在第一小区中，方法包括：终端设备基于第一NCD-SSB频点对第一小区进行测量，以及基于第一NCD-SSB频点和/或CD-SSB频点对第二小区进行测量。终端设备根据第一小区的测量结果以及第二小区的测量结果进行小区重选。
本申请实施例提供一种基于NCD-SSB频点进行测量的方式，使得终端设备可以在没有配置CD-SSB频点或者基于CD-SSB频点无法进行小区重选的情况下，可以基于NCD-SSB频点进行小区重选，可以避免由于无法进行小区重选导致终端设备的通信性能较差的问题，因此，通过本申请实施例提供的方法可以提升小区重选的灵活性，还可以提升终端设备的通信性能。
一种可能的设计中，终端设备基于第一NCD-SSB频点对第二小区进行测量，包括：终端设备根据来自网络设备的第一信息，基于第一NCD-SSB频点对第二小区进行测量，第一信息用于指示第一NCD-SSB频点可用于邻区测量。上述方式中，终端设备可以在网络设备的指示下进行邻区测量，从而可以提升小区重选的灵活性。
一种可能的设计中，终端设备基于第一NCD-SSB频点和CD-SSB频点对第二小区进行测量，包括：终端设备基于第一NCD-SSB频点对第二小区进行测量；终端设备根据第二小区的测量结果确定第二小区不能作为重选的目标小区；终端设备基于CD-SSB频点对第二小区进行测量。通过上述设计，可以在第一NCD-SSB频点无法进行小区重选的情况 下，可以基于CD-SSB频点进行小区重选，从而可以避免由于无法进行小区重选导致终端设备的通信性能较差的问题。
一种可能的设计中，在终端设备基于第一NCD-SSB频点对第二小区进行测量之前，方法还包括：终端设备接收来自网络设备的第二信息，第二信息用于指示根据CD-SSB频点对邻区进行测量。上述方式中，终端设备可以在网络设备的指示下进行邻区测量，从而可以提升小区重选的灵活性。
一种可能的设计中，终端设备基于CD-SSB频点对第二小区进行测量，包括：终端设备根据来自网络设备的第三信息，基于CD-SSB频点对第二小区进行测量，第三信息用于指示只可基于CD-SSB频点进行邻区测量。上述方式中，终端设备可以在网络设备的指示下进行邻区测量，从而可以提升小区重选的灵活性。
一种可能的设计中，在终端设备基于第一NCD-SSB频点和/或CD-SSB频点对第二小区进行测量之前，方法还包括：终端设备确定第一小区的测量结果满足第一NCD-SSB频点对应的阈值，其中，第一NCD-SSB频点对应的阈值为网络设备配置的，或者，第一NCD-SSB频点对应的阈值为根据CD-SSB频点对应的阈值以及第一小区的功率补偿值确定的。上述设计，通过功率补偿值可以降低发射功率不同对小区重选带来的影响，例如，假设第一小区在第一NCD-SSB频点上的参考信号的发送功率比CD-SSB频点上的参考信号的发送功率不同，因此终端设备基于第一NCD-SSB频点和CD-SSB频点确定的第一小区的测量结果不同，从而得到的小区重选结果可能不同，上述方式通过功率补偿值可以将基于不同频点的测量结果进行拉齐，从而可以提升小区重选的准确性。
一种可能的设计中，方法还包括：终端设备接收来自网络设备的第四信息，第四信息用于指示第一小区的功率补偿值。通过该设计，使得终端设备可以将基于不同频点的测量结果进行拉齐，从而可以提升小区重选的准确性。
一种可能的设计中，终端设备根据第一小区的测量结果以及第二小区的测量结果进行小区重选，包括：终端设备根据第一小区的测量结果确定第一小区的R值；终端设备根据第二小区的测量结果确定第二小区的R值；终端设备根据第一小区的R值以及第二小区的R值进行小区重选。
一种可能的设计中，终端设备根据第一小区的测量结果确定第一小区的R值，包括：终端设备根据第一小区的测量结果以及第一小区的功率补偿值确定第一小区的R值。上述设计，上述方式通过功率补偿值可以将基于不同频点的测量结果进行拉齐，从而可以降低发射功率不同对小区重选带来的影响，提升小区重选的准确性。
一种可能的设计中，终端设备根据第二小区的测量结果确定第二小区的R值，包括：终端设备根据第二小区的测量结果以及第二小区的功率补偿值确定第二小区的R值。上述方式通过功率补偿值可以将基于不同频点的测量结果进行拉齐，从而可以降低发射功率不同对小区重选带来的影响，提升小区重选的准确性。
一种可能的设计中，方法还包括：终端设备接收来自网络设备的第五信息，第五信息用于指示第二小区的功率补偿值。上述设计，使得终端设备可以基于功率补偿值将不同频点的测量结果进行拉齐。
第二方面，本申请提供一种通信方法，该方法的执行主体可以是网络设备，也可以是网络设备中的芯片或电路。以网络设备为例，方法包括：网络设备根据第二小区的NCD-SSB频点的配置确定指示信息，指示信息用于指示终端设备对第二小区进行测量时采用第一 NCD-SSB频点和/或CD-SSB频点，终端设备在空闲态或者非激活态驻留在第一小区中；网络设备向终端设备发送该指示信息。
本申请实施例提供一种基于NCD-SSB频点进行测量的方式，使得终端设备可以在没有配置CD-SSB频点或者基于CD-SSB频点无法进行小区重选的情况下，可以在网络设备的指示下进行小区重选，从而可以提升小区重选的灵活性，还可以提升终端设备的通信性能。
一种可能的设计中，指示信息指示终端设备对第二小区进行测量时采用第一NCD-SSB频点，具体包括：指示信息指示第一NCD-SSB频点可用于邻区测量。
通过该方式，使得终端设备可以基于第一NCD-SSB频点对邻区进行测量，不需要终端设备因为测量而切换BWP，因此可节省终端设备的功耗。例如，终端设备可以直接在包含第一NCD-SSB频点的BWP上接收寻呼以及发起随机接入(random access channel,RACH)，而不是基于CD-SSB频点进行同步以及测量后，再转移到包含第一NCD-SSB频点的BWP进行接收寻呼以及RACH，从而可以实现更加快速的接入，以及，减少空闲态频繁在不同BWP上切换。
一种可能的设计中，指示信息指示终端设备对第二小区进行测量时采用第一NCD-SSB频点和CD-SSB频点，具体包括：指示信息指示根据CD-SSB频点对邻区进行测量。
通过该方式可以测量未配置第一NCD-SSB频点的邻区进行测量，从而可以提升邻区的测量结果的准确性，使得终端设备可以重选到信号质量更好的邻区中进行通信，提升终端设备的通信性能。
一种可能的设计中，指示信息指示终端设备对第二小区进行测量时采用CD-SSB频点，具体包括：指示信息指示只可基于CD-SSB频点进行邻区测量。
该方式通过基于第一NCD-SSB频点和CD-SSB频点邻区的进行测量，可以提升邻区的测量结果的准确性，使得终端设备可以重选到信号质量更好的邻区中进行通信，提升终端设备的通信性能。
一种可能的设计中，方法还包括：网络设备向终端设备发送第四信息和/或第五信息，第四信息用于指示第一小区的功率补偿值，第五信息用于指示第二小区的功率补偿值。通过该设计，使得终端设备可以将基于不同频点的测量结果进行拉齐，从而可以提升小区重选的准确性。

具体实施方式
下面将结合附图对本申请作进一步地详细描述。
以下，对本申请实施例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，可以为具有无线收发功能的设备或可设置于任一设备中的芯片，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、XR设备(如VR设备、AR设备、MR设备等)、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、视频监控中的无线终端以及可穿戴终端设备等。终端设备还可以是eMBB UE、URLLC UE、无人机、其他物联网(internet of things，IoT)设备、定位设备、上文术语介绍1)中所述的能力降低的终端设备等。
网络设备，可以为用于实现接入网设备的功能的装置，接入网设备可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，例如可以是NR系统中的下一代基站(next Generation node B，gNB)，可以是长期演进(long term evolution，LTE)系统中的演进型基站(evolutional node B，eNB)等。网络设备，也可以为能够支持网络设备实现该接入网设备功能的装置，例如芯片系统，该装置可以被安装在网络设备中。
2)能力降低(reduced capability，REDCAP)的终端设备(REDCAP UE)包括3GPP Rel-17 和3GPP Rel-18定义的REDCAP UE，具体的，可以具有如下至少一项特征：
1.在频段(frequency range，FR)1初始接入时和/或初始接入后的最大带宽不超过20MHz。在FR 2初始接入时和/或初始接入后的最大带宽不超过100MHz，在3GPP Rel-18中定义的REDCAP终端设备所支持的最大带宽为5MHz。
2.支持的接收天线(Rx)分支的最小数量为1。
3.协议版本为NR Rel-17或以上。
4.仅支持半双工频分双工(frequency division duplex，FDD)。
5.若具有1Rx分支，支持1个下行(downlink，DL)最大多入多出(multiple-in multiple-out，MIMO)层。若具有2个Rx分支，支持2个DL MIMO层。
能力降低的终端设备可以理解为是相对于传统终端设备(legacy UE)降低了能力的终端设备，所述能力包括但不限于上述五个方面的特征，其中，传统终端设备可以例如为增强移动宽带(enhanced Mobile Broadband,eMBB)终端设备或超高可靠低时延通信(ultra-reliable low-latency communication,URLLC)终端设备。
3)S准则
S准则指终端设备选择驻留的小区的参考信号接收功率(reference signal received power，RSRP)相关的测量值(下面称为Srxlev值)应大于0，且，参考信号接收质量(reference signal received quality，RSRQ)相关的测量值(下面称为Squal值)应大于0，也就是，终端设备选择Srxlev值大于0且Squal值大于0的小区进行驻留。
其中，Srxlev值满足如下公式：Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–Qoffsettemp。其中，Qrxlevmeas为在该小区测量得到的接收电平值，Qrxlevmin为最小接收电平值，Qrxlevminoffset为最小接收电平值偏置，Pcompensation等于MAX(PEMAX－PUMAX，0)，PEMAX为终端设备配置的最大上行可用的发射功率，PUMAX为终端设备的最大发射功率，由终端设备自身的能力等级来决定。Qoffsettemp为临时功率补偿。
Squal值满足如下公式：Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)–Qoffsettemp。其中，Qqualmeas为在该小区测量得到的小区信号质量值。Qqualmin为最小信号质量值。Qqualminoffset为最小信号质量值偏置。Qoffsettemp为临时功率补偿。
4)R准则
小区重选指终端设备在处于空闲态时通过监测邻区和当前驻留的小区(下面称为服务小区)的信号质量以选择一个最好的小区提供服务信号的过程。其中，邻区可以包括同频邻区、异频邻区，当然也可以包括其他类型的邻区，这里不再一一列举。同频邻区为与服务小区中心频点相同的邻区，如图1所示，异频邻区为与服务小区的中心频点不同的邻区，如图2所示。在同频邻区中进行小区重选的过程可以称为同频小区重选，在异频邻区中进行小区重选的过程可以称为异频小区重选。对于同频邻区或者异频但具有同等优先级的邻区，终端设备可以根据R准则对邻区进行重选排序。
R准则用于小区重选过程中确定目标小区。R准则为：若在检测时间内邻区的R值均超过服务小区的R值，则该邻区可以作为小区重选的候选小区。其中，邻区的R值满足如下公式：Rn＝Qmeas,n-Qoffset–Qoffsettemp，Rn为邻区的R值，Qmeas,n为邻区的信号的测量量，Qoffset为小区偏置，Qoffsettemp为邻区的临时补偿值。且服务小区的R值满足如下公式：Rs＝Qmeas,s+Qhyst–Qoffsettemp，Rs值为服务小区的R值，Qmeas,s为服 务小区的信号的测量量，Qhyst为小区重选迟滞值，Qoffsettemp为服务小区的临时补偿值。
如图3所示，小区重选的过程可以包括：
S301，终端设备根据测量启动标准，对邻区进行信号测量。
在同频小区重选过程中，测量启动标准可以为：当服务小区的信号满足Srxlev>SIntraSearchP且Squal>SIntraSearchQ时，终端设备可以不对同频邻区进行信号测量，否则执行对同频邻区的信号测量。SIntraSearchP和SIntraSearchQ为启动同频小区信号测量的门限值，可以是网络设备通过系统消息广播的。
在异频或异系统小区重选过程中，网络设备可以对各频点设置优先级。对于高优先级频点邻区，其中，高优先级频点邻区的频点的优先级高于服务小区的频点的优先级，终端设备可以总是执行对这些邻区的信号测量。对于同优先级频点邻区和低优先级频点邻区，其中，同优先级频点邻区的频点的优先级等于服务小区的频点的优先级，低优先级频点邻区的频点的优先级低于服务小区的频点的优先级，测量启动标准可以为：当服务小区的信号满足Srxlev>SnonIntraSearchP且Squal>SnonIntraSearchQ时，终端设备可以不对这些异频邻区进行信号测量，否则可以执行对异频邻区的信号测量。SnonIntraSearchP和SnonIntraSearchQ为启动异频邻区信号测量的门限值，可以是网络设备通过系统消息广播的。
其中，服务小区的Srxlev和Squal可以参阅上述术语介绍3)的相关描述，这里不再赘述。
S302，终端设备根据对邻区的测量结果确定目标小区。
在同频小区重选过程中，终端设备可以将满足R准则的候选邻区的R值进行排序，终端设备可以选择R值最高的小区作为目标小区。
在异频小区重选过程中，对于高优先级频点邻区，终端设备可以将满足如下条件的候选邻区中频点的优先级最高的邻区作为目标小区：邻区的Srxlev和Squal均满足对应的门限值，且持续时间大于预设时长，该门限值为邻区的用于高优先级频点邻区重选的门限值。
若没有高优先级频点邻区符合小区重选的条件，终端设备可以在同优先级频点邻区中选择目标小区，终端设备可以将满足R准则的候选邻区的R值进行排序，终端设备可以选择R值最高的小区作为目标小区。
若没有高优先级频点邻区和同优先级频点邻区符合小区重选的条件，终端设备可以在低优先级频点邻区中选择目标小区。对于低优先级频点邻区，若服务小区的Srxlev和Squal均小于对应的门限值，该门限值为服务小区的用于低优先级频点邻区重选的门限值，且邻区的Srxlev和Squal均大于对应的门限值，该门限值为邻区的用于低优先级频点邻区重选的门限值，且持续时间大于预设时长。
5)CD-SSB
CD-SSB是指关联于系统信息块(system information block，SIB)1的SSB。例如，CD-SSB是能够配置小区的必要信息(如控制资源集(control-resource set，CORESET)#0和/或SIB1)的SSB。其中，CORESET#0可用于终端设备解析SIB1，SIB1是用于提供小区特性信息的SIB，比如，SIB1包括非接入(non-access，NAS)层的系统信息。另外，本申请中所述的CD-SSB频点是指CD-SSB的频点，也就是CD-SSB对应的频率位置。
6)NCD-SSB
NCD-SSB是指不与SIB1关联的SSB，例如，NCD-SSB缺少用于配置小区的完整信 息，例如，NCD-SSB仅包括SSB，或者缺少SIB1的必要字段。另外，本申请中所述的NCD-SSB频点是指NCD-SSB的频点，也就是NCD-SSB对应的频率位置。
本申请实施例中的术语“系统”和“网络”可被互换使用，“频点”和“频率”可被互换使用。“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的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC或ABC。以及，除非有特别说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两个信息的内容、优先级或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
5G标准目前同意基于SSB进行测量。空闲状态的终端设备可以基于SSB进行小区重选。目前，终端设备基于SSB进行小区重选时是基于CD-SSB频点的。但是终端设备的初始BWP上可能不存在CD-SSB，导致终端设备无法正常进行小区重选，进而导致通信中断，或者通信质量差等问题。例如，目前在针对RedCap UE的讨论中，支持将RedCap UE专用的部分带宽(bandwidth part，BWP)设置在载波边缘。其中，RedCap UE专用的BWP包括但不限于RedCap UE专用的初始(initial)BWP。例如，RedCap UE的专用BWP可包括初始上行(uplink，UL)BWP和初始下行(downlink，DL)BWP，其中，初始上行BWP的中心频点和初始下行BWP的中心频点相同，又考虑到目前的时分双工(time division duplexing，TDD)UE只有一个锁相环，因此，目前的RedCap UE的专用BWP可能未配置CD-SSB频点。例如，如图4所示，小区1包括BWP#0，BWP#2和BWP#3，其中，BWP#0上包含CD-SSB，BWP#2上即不包含CD-SSB也不包含NCD-SSB，BWP#3上包含NCD-SSB，不包含CD-SSB，若终端设备的初始BWP被配置为BWP#2或BWP#3，则终端设备的初始BWP上不存在CD-SSB。这种场景中，终端设备无法基于CD-SSB频点进行小区重选，导致终端设备的通信质量较差甚至会产生中断。
因此，如何提升终端设备的通信性能成为亟待解决的技术问题。
基于此，本申请实施例提供一种通信方法及装置，用于提高终端设备的通信性能。其中，方法和装置是基于同一构思的，由于方法及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。
本申请提供的通信方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)、窄带物联网(narrow band internet of things，NB-IoT)、LTE，也可以是第五代(5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(new radio，NR)系统以及6G或者未来通信发展中出现的新的通信系统等。
图5示出了本申请实施例提供的通信方法可适用的通信系统的架构，所述通信系统的 架构中可以包括网络设备和终端设备。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题同样适用。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
本申请提供的方法可以应用于终端设备，该终端设备在空闲态或者非激活态驻留在第一小区中。下面对该终端设备的同频小区重选方法和异频小区重选方法分别进行说明。
参见图6，为本申请提供的一种同频小区重选方法的流程示意图。该方法包括：
S601，终端设备基于第一NCD-SSB频点对第一小区进行测量。
应理解，S601仅为“终端设备对第一小区进行测量”的一种可能的实现方式，在具体实施中，可以通过其他方式对第一小区进行测量。如终端设备也可以基于CD-SSB频点对第一小区进行测量，得到第二测量结果。又如，终端设备可以基于第一NCD-SSB频点和基于CD-SSB频点对第一小区进行测量。终端设备根据第一测量结果和第二测量结果确定第一小区的测量结果。
为了将上述实现方式进行区分，可以将基于第一NCD-SSB频点对第一小区进行测量的实现方式称为方式1.1，将基于CD-SSB频点对第一小区进行测量的实现方式称为方式1.2，将基于第一NCD-SSB频点和基于CD-SSB频点对第一小区进行测量的实现方式称为方式1.3。
方式1.3的一种可能的实施方案为，终端设备可以将基于第一NCD-SSB频点对第一小区进行测量得到的第一测量结果和基于CD-SSB频点对第一小区进行测量得到的第二测量结果的平均值作为第一小区的测量结果。
方式1.3的另一种可能的实施方案为，终端设备可以将基于第一NCD-SSB频点对第一小区进行测量得到的第一测量结果和基于CD-SSB频点对第一小区进行测量得到的第二测量结果的加权和作为第一小区的测量结果。
一种可能的实施方式中，在步骤S602之前，终端设备可以确定第一小区的测量结果满足第一NCD-SSB频点对应的阈值，其中，第一NCD-SSB频点对应的阈值为网络设备配置的，或者，第一NCD-SSB频点对应的阈值为根据CD-SSB频点对应的阈值以及第一小区的功率补偿值确定的。
例如，终端设备可以确定第一小区的测量结果满足如下公式时，执行如下步骤S602：
SrxlevNCD-SSB≤SIntraSearchPNCD-SSB，且，SqualNCD-SSB≤SIntraSearchQNCD-SSB，其中，SrxlevNCD-SSB和SqualNCD-SSB根据第一小区的测量结果确定，SIntraSearchPNCD-SSB和SIntraSearchQNCD-SSB为第一NCD-SSB对应的启动同频小区信号测量的门限值，其中，SIntraSearchPNCD-SSB和SIntraSearchQNCD-SSB为网络设备配置的，例如，网络设备可以通过SIB1等系统消息广播第一NCD-SSB对应的启动同频小区信号测量的门限值SIntraSearchPNCD-SSB和SIntraSearchQNCD-SSB。

上述SrxlevNCD-SSB和SqualNCD-SSB的确定方式可以参阅前文术语介绍3)中Srxlev和Squal的确定方式，这里不再重复赘述。
S602，终端设备对第二小区进行测量。
一种实现方式，终端设备可以对一个或多个邻区进行测量，第二小区为该一个或多个邻区中的任一小区，本申请实施例以第二小区为例介绍终端设备对邻区进行测量的方式，其他邻区的测量方式可以参阅第二小区的测量方式。
具体的，终端设备可以通过如下三种方式中任一方式对第二小区进行测量：
方式2.1，终端设备可以基于第一NCD-SSB频点对第二小区进行测量。通过该方式，使得终端设备可以基于第一NCD-SSB频点对邻区进行测量，不需要终端设备因为测量而切换BWP，因此可节省终端设备的功耗。例如，终端设备可以直接在包含第一NCD-SSB频点的BWP上接收寻呼以及发起RACH，而不是基于CD-SSB频点进行同步以及测量后，再转移到包含第一NCD-SSB频点的BWP进行接收寻呼以及RACH，从而可以实现更加快速的接入，以及，减少空闲态频繁在不同BWP上切换。
方式2.2，终端设备也可以基于CD-SSB频点对第二小区进行测量。通过该方式可以测量未配置第一NCD-SSB频点的邻区进行测量，从而可以提升邻区的测量结果的准确性，使得终端设备可以重选到信号质量更好的邻区中进行通信，提升终端设备的通信性能。
方式2.3，终端设备可以基于第一NCD-SSB频点和CD-SSB频点对第二小区进行测量。该方式通过基于第一NCD-SSB频点和CD-SSB频点邻区的进行测量，可以提升邻区的测量结果的准确性，使得终端设备可以重选到信号质量更好的邻区中进行通信，提升终端设备的通信性能。
例如，终端设备可以基于第一NCD-SSB频点对第二小区进行测量，得到第三测量结果，基于CD-SSB频点对第二小区进行测量，得到第四测量结果。终端设备根据第三测量结果和第四测量结果确定第二小区的测量结果。举例说明，可以将第三测量结果和第四测量结果的平均值作为第二小区的测量结果。或者，可以将第三测量结果和第四测量结果的加权和作为第一小区的测量结果。
又例如，终端设备可以基于第一NCD-SSB频点对包括第二小区在内的多个邻区进行测量。终端设备根据该多个邻区的测量结果确定该多个邻区不能作为重选的目标小区，或者该频点没有检测到邻区，则基于CD-SSB频点对该多个邻区进行测量。
再例如，终端设备可以基于第一NCD-SSB频点对至少一个第一邻区进行测量，基于CD-SSB频点对至少一个第二邻区进行测量。其中，第二小区可以属于上述第一邻区，也可以属于上述第二邻区。
一种实现方式中，终端设备也可以在网络设备的指示下确定采用上述方式2.1或者上述方式2.2或者上述方式2.3对第二小区进行测量，例如，网络设备可以根据第二小区的 NCD-SSB频点的配置确定终端设备对第二小区进行测量采用的频点。
例如，网络设备向终端设备发送第一信息。其中，第一信息用于指示第一NCD-SSB频点可用于邻区测量，或者，第一信息指示基于第一NCD-SSB频点进行邻区测量，或者，第一信息指示第一NCD-SSB频点上的邻区足够进行小区重选，或者，第一信息指示可以只基于第一NCD-SSB频点进行邻区测量。相应的，终端设备可以根据第一信息采用上述方式2.1对第二小区进行测量。
又例如，网络设备向终端设备发送第二信息，第二信息指示根据CD-SSB频点对邻区进行测量，或者，第二信息指示结合CD-SSB频点对邻区进行测量，或者，第二信息指示在进行邻区测量时采用第一NCD-SSB和CD-SSB频点，或者，第二信息指示CD-SSB可用于邻区测量，或者只基于CD-SSB进行邻区测量。相应的，终端设备可以根据第二信息采用上述方式2.3对第二小区进行测量。
再例如，网络设备向终端设备发送第三信息，第三信息用于指示只可基于CD-SSB频点进行邻区测量。相应的，终端设备可以根据第三信息采用上述方式2.2对第二小区进行测量。一种示例性说明中，“只可基于CD-SSB频点进行邻区测量”可以理解为在对邻区进行测量时只可基于CD-SSB频点对邻区进行测量。
另一种实现方式中，终端设备也可以自主确定邻区测量的方式。例如，终端设备可以基于第一NCD-SSB频点对包括第二小区在内的多个邻区进行测量，若该多个邻区不能作为重选的目标小区，则终端设备基于CD-SSB频点对该多个邻区进行测量。
S603，终端设备根据第一小区的测量结果以及第二小区的测量结果进行小区重选。
一种实现方式中，终端设备可以根据第一小区的测量结果确定第一小区的R值，根据第二小区的测量结果确定第二小区的R值。终端设备根据第一小区的R值以及第二小区的R值进行小区重选。
可选的，终端设备在确定第一小区的R值时，可以根据第一小区的测量结果以及第一小区的功率补偿值确定。例如，Rs＝Qmeas,s+Qhyst–Qoffsettemp+offset1，其中，Rs、Qmeas,s、Qhyst、Qoffsettemp的含义可以参阅前文术语介绍4)的相关描述，offset1为第一小区对应的功率偏移值。
一种实施方式中，第一小区的功率补偿值可以是网络设备广播的，例如，网络设备可以在第一小区在第一NCD-SSB频点上的参考信号的功率与在CD-SSB频点上的参考信号的功率不一致时，广播第一小区的功率补偿值。
上述方式可以通过功率补偿值可以降低发射功率不同对小区重选带来的影响，例如，假设第一小区在第一NCD-SSB频点上的参考信号的发送功率比CD-SSB频点上的参考信号的发送功率不同，因此终端设备基于第一NCD-SSB频点和CD-SSB频点确定的第一小区的测量结果不同，从而得到的小区重选结果可能不同，上述方式通过功率补偿值可以将基于不同频点的测量结果进行拉齐，从而可以提升小区重选的准确性。
可选的，终端设备在确定第二小区的R值时，可以根据第二小区的测量结果以及第二小区的功率补偿值确定。例如，Rn＝Qmeas,n-Qoffset–Qoffsettemp+offset2，其中，Rn、Qmeas,n、Qoffset、Qoffsettemp的含义可以参阅前文术语介绍4)的相关描述，offset2为第二小区对应的功率偏移值。
一种实施方式中，第二小区的功率补偿值可以是网络设备广播的，例如，若终端设备基于上述方式a或上述方式c对第二小区进行测量，网络设备可以在第二小区在第一 NCD-SSB频点上的参考信号的功率与在CD-SSB频点上的参考信号的功率不一致时，广播第二小区的功率补偿值。
上述方式通过功率补偿值可以将基于不同频点的测量结果进行拉齐，从而可以降低发射功率不同对小区重选带来的影响，提升小区重选的准确性。例如，终端设备重选到第二小区后，可能驻留在第二小区的其他频点上例如CD-SSB频点，上述设计通过功率补偿值可以将基于不同频点的测量结果进行拉齐，可以提升小区重选的准确性。
可选的，网络设备可以在系统消息中配置至少一个NCD-SSB频点。具体实现中，网络设备可以通过显示或者隐示的方式指示NCD-SSB频点对应的小区。
一种实现方式中，网络设备可以通过NCD-SSB频点关联的CD-SSB频点指示该NCD-SSB频点对应的小区。具体的，网络设备可以通过显示或者隐示的方式指示NCD-SSB频点与CD-SSB频点之间的关联关系。例如，网络设备可以通过频点的排序序号指示NCD-SSB频点关联的CD-SSB频点，举例说明，第二NCD-SSB频点为NCD-SSB频点列表中排序序号为3，则第二NCD-SSB频点与CD-SSB频点列表中排序序号为3的CD-SSB频点具有关联关系。
另一种实现方式中，网络设备可以广播NCD-SSB频点列表，其中，该NCD-SSB频点列表包括至少一个NCD-SSB频点，以及每个NCD-SSB频点对应的物理小区标识(physical cell identifier，PCI)。其中，同一个PCI关联的NCD-SSB频点属于同一个小区。
另一种实现方式中，网络设备可以广播邻区列表，其中，该邻区列表包括至少一个邻区，可选的包含每个邻区对应的NCD-SSB频点和/或CD-SSB频点，即每个邻区的配置中包含对应的NCD-SSB频点和/或CD-SSB频点。一种可能的实施方式中，对于同频邻区，网络设备可以不指示该邻区的CD-SSB频点。

一种实现方式中，以该一个或多个邻区中的第二小区为例，若终端设备基于第一NCD-SSB频点测量第二小区，则终端设备可以根据第二小区基于第一NCD-SSB频点的测量结果以及第二小区的功率补偿值确定第二小区的R值。例如，以上述方式2.1测量第二小区为例，第二小区的R值可以满足如下条件：Rn＝Qmeas,n-Qoffset–Qoffsettemp+offset2，其中，Rn、Qmeas,n、Qoffset、Qoffsettemp的含义可以参阅前文术语介绍4)的相关描述，offset2为第二小区对应的功率偏移值。
可选的，若步骤S701中终端设备基于第一NCD-SSB频点测量第一小区，则终端设备可以根据第以小区基于第一NCD-SSB频点的测量结果以及第一小区的功率补偿值确定第一小区的R值。例如，以上述方式1.1测量第一小区为例，第一小区的R值可以满足如下条件：Rs＝Qmeas,s+Qhyst–Qoffsettemp+offset1，其中，Rs、Qmeas,s、Qhyst、Qoffsettemp的含义可以参阅前文术语介绍4)的相关描述，offset1为第一小区对应的功率偏移值。

并且，终端设备可以基于NCD-SSB频点对同频邻区进行测量，不需要终端设备因为测量而切换BWP，因此可节省终端设备的功耗。例如，终端设备可以直接在包含该NCD-SSB频点的BWP上接收寻呼以及发起RACH，而不是基于CD-SSB频点进行同步以及测量后，再转移到包含第一NCD-SSB频点的BWP进行接收寻呼以及RACH，从而可以实现更加快速的接入，以及，减少空闲态频繁在不同BWP上切换。
并且，本申请实施例中通过功率补偿值可以降低发射功率不同对小区重选带来的影响。
上面介绍了同频小区重选的方法，下面介绍异频小区重选的方法。其中，异频小区重 选的方法中，对于同优先级频点邻区，小区重选的方法与上述图6和图7所述的同频小区重选方法类似，区别在于，同频小区重选方法中启动同频小区重选时终端设备采用的是启动同频小区信号测量的门限值，而异频小区重选的方法中启动异频小区重选时终端设备采用的是启动异频小区信号测量的门限值。具体可以参阅上述图6和图7所述的同频小区重选方法，重复之处不再赘述。
