Description

通信方法与通信装置
本申请要求于2022年2月14提交中国国家知识产权局、申请号为202210133059.2、申请名称为“通信方法与通信装置”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
本申请实施例涉及通信技术领域，更具体地，涉及一种通信方法与通信装置。
背景技术
卫星通信网络是一个由一定数量的低轨卫星组成的大规模星座向终端设备提供星地通信服务的通信网络。例如，该大规模星座可以是由上万颗低轨卫星组成。假设，一颗低轨卫星的覆盖区域规划为一个小区且一个小区的物理小区标识(physical cell identity，PCI)与一颗低轨卫星关联，则会有上万个小区，在这上万个小区中又会存在PCI相同的多个小区。
随着低轨卫星的移动和覆盖区域的改变，同一地点被不同低轨卫星覆盖时的PCI会发生变化。多个邻区的PCI可能会相同，这会产生一些问题。例如，一个驻留小区的两个或两个以上邻区具有相同PCI时，网络设备无法完成终端设备从驻留小区到目标邻区的正确切换。
因此，如何避免大规模星座通信系统中邻区之间发生小区标识混淆或冲突是亟待解决的技术问题。

本申请实施例中的网络设备具有无线收发功能的设备，用于与终端设备进行通信。接入网设备可以为无线接入网(radio access network，RAN)中的节点，又可以称为基站，还可以称为RAN节点。可以是LTE中的演进型基站(evolved Node B，eNB或eNodeB)；或者gNodeB(gNB)等5G网络中的基站或者5G之后演进的公共陆地移动网络(public land mobile network，PLMN)中的基站，宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机或者非第三代合作伙伴项目(3rd generation partnership project，3GPP)接入设备等。可选的，本申请实施例中的网络设备可以包括各种形式的基站，例如：宏基站、微基站(也称为小站)、中继站、WiFi系统中的接入节点，传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心以及设备到设备(Device-to-Device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备等，还可以包括云接入网(cloud radio access network，C-RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)、NTN通信系统中的网络设备，本申请实施例对此不作具体限定。

应理解，本申请实施例揭示的技术方案还可以应用于多卫星设备的通信场景。图1所示的内容仅作为示例性理解。
为便于理解本申请实施例揭示的技术方案，下文将对本申请实施例的相关技术术语进行简单的介绍。
第一，PCI
PCI是用于区分不同小区的无线信号，保证在相关小区覆盖范围内没有相同的物理小区标识。PCI是由小区标识1和小区标识组成，计算关系为：
其中，该是用于表示PCI的值。终端根据同步信号和物理广播信道块 (synchronization signal and physical broadcast channel block，SSB)的主同步信号(primary synchronization signals，PSS)使用的m序列确定小区标识2的值，例如，m序列为3条长度为127比特的序列，则该小区标识的取值范围为0～2。终端根据SSB中的辅同步信号(secondary synchronization signals，SSS)使用的gold序列确定小区标识1值，例如，每一个PSS对应336条长度为127比特的SSS序列，则该小区标识1的取值范围为0～335。因此，的取值范围为0～1007，最大可以支持1008个小区的PCI不重复命名。
当卫星通信系统中卫星设备的数量多于1008个时，该卫星通信系统会存在不同小区的PCI相同的情形。随着星座规模的不断增大，多个邻区出现相同PCI的情形也将变得更为常见。这会产生一些问题，如终端的邻区切换失败。具体可以见下文图2所示的内容。
邻区是指：相邻小区。邻区包括：一阶邻区、二阶邻区和多阶邻区。一阶邻区是指邻区关系中直接相邻的小区。二阶邻区是指邻区关系中间隔一个小区的小区。多阶邻区是指邻区关系中间隔两个以上(包含两个)小区的小区。
邻区关系是指：相邻小区之间的关系。邻区关系包括：一阶邻区关系、二阶邻区关系和多阶邻区关系。一阶邻区关系是指两个小区直接相邻。二阶邻区关系是指两个小区之间间隔一个小区。多阶邻区关系是指两个小区之间间隔两个以上(包含两个)的小区。
示例性地，Cell A和Cell B互为一阶邻区，Cell A和Cell D互为二阶邻区。换言之，Cell A的一阶邻区是Cell B，Cell A的二阶邻区是Cell D。Cell B的一阶邻区是Cell A，Cell D的二阶邻区是Cell A。
图2是本申请实施例提供的一阶邻区/二阶邻区PCI冲突的示意图。图2a示出的是一阶邻区PCI冲突的示意图。图2b示出的是二阶邻区PCI冲突的示意图(二阶邻区PCI冲突也可以理解是二阶邻区PCI混淆)。黑色箭头用于表示终端设备的移动方向。图2所示的内容仅作为示例性理解，不作为对本申请实施例要求的保护范围的限定。
在图2a中，Cell A和Cell E具有相同的PCI，Cell A与Cell E互为一阶邻区。终端从驻留小区Cell B切换到Cell A和Cell E的其中一个小区时，Cell B对应的源gNB不能根据终端上报的PCI区分出终端需要切换到哪个小区，这会造成源gNB可能向错误的目标gNB发送切换请求，造成切换失败。
在图2b中，Cell A和Cell C具有相同的PCI，Cell A与Cell C互为二阶邻区。Cell A和Cell C均与Cell B小区相邻，终端驻留在Cell B小区，当终端向Cell A小区移动，并向Cell B对应的源gNB上报测量结果(该测量结果包括一个小区的PCI为1)，Cell B对应的源gNB无法根据终端上报的PCI区分出终端究竟测量的是哪个小区，这会造成源gNB无法完成切换或者源gNB向错误的相邻gNB(目标gNB)发送切换请求。
正如图2所示，一阶邻区/二阶邻区PCI冲突会使得网络设备在终端需要进行切换时无法正确完成终端从驻留小区到目标邻区的切换行为。因此，大规模的星座通信系统需要避免多个PCI相同的邻区之间发生冲突的问题，或者说，大规模星座通信系统中需要避免邻区之间发生小区标识混淆或冲突的问题。
应理解，图2所示的问题仅是多个PCI相同的邻区之间发生冲突的一种示例，本申请实施例不限定多个PCI相同的邻区之间发生冲突的其他示例。
为便于描述，本申请实施例采用图2所示的问题进行描述，但是该描述并不能排除多 个PCI相同的邻区之间发生冲突的其他示例。
应理解，除了多个PCI相同的邻区之间会发生冲突之外，多个PCI mod N相同的相邻小区之间也可能发生冲突。例如，物理上行共享信道(physical uplink shared channel，PUSCH)/物理上行控制信道(physical uplink control channel，PUCCH)的解调参考信号(demodulation reference signal，DMRS)和探测参考信号(sounding reference signal，SRS)与ZC序列关联，ZC序列有30组根，根与PCI关联。如果相邻小区的PCI满足mod N关系(mod表示取模)且使用相同频率，那么上行参考信号之间也会产生干扰。因此，需要相邻小区避免PCI mod N相同。其中，N为正整数，例如N可以等于30，也可以是其他数值。
鉴于上述技术问题，本申请实施例提供一种通信方法与通信装置，能够解决大规模的星座通信系统中多个PCI(或者PCI mod N)相同的邻区之间发生冲突的问题，或者说，能够解决大规模星座通信系统中邻区之间发生小区标识混淆或冲突的问题。
图3是本申请实施例提供的通信方法的示意流程图。该方法包括：
S310，第二通信装置向第一通信装置发送第一配置信息。
相应的，第一通信装置接收第二通信装置发送的第一配置信息。
该第一配置信息包括第二通信装置的第一小区的第一标识更新信息和第一更新时刻信息，该第一标识更新信息用于确定第一小区在第一更新时刻或者第一更新时刻之后使用的第一标识信息。
一个可能的实现中，第二通信装置向第一通信装置发送的第一配置信息可以是根据星历信息确定的。例如，第二通信装置可以根据星历信息确定其各个小区的标识信息以及更新时间信息，从而确定第一配置信息。又例如，地面网络管理单元/网关根据星历信息配置该第二通信装置的各个小区的标识信息以及更新时间信息，并将该标识信息以及更新时间信息发送给第二通信装置，然后第二通信装置将各个小区的标识信息以及更新时间信息发送给各个小区覆盖范围内的第一通信装置。更具体的，地面网络管理单元/网关可以根据卫星星座以及小区分布等信息确定第一配置信息，并向第二通信装置发送将该第一配置信息，进一步地，第二通信装置将该第一配置信息发送给第一通信装置。
第一通信装置可以是一个小区覆盖范围内的任意一个终端设备(后文以终端设备代指第一通信装置进行描述)，第二通信装置可以是该小区对应的网络设备(后文以网络设备代指第二通信装置进行描述)。该小区可以是第一小区。因此，上述内容可以理解为：第一小区对应的网络设备向第一小区覆盖范围内的终端设备发送第一配置信息。
其中，该第一配置信息包括第一小区的两个参数：第一标识更新信息和第一更新时刻的信息。第一标识更新信息是用于确定第一小区在第一更新时刻或者第一更新时刻之后使用的第一标识信息的信息。第一更新时刻的信息是用于指示第一小区的标识信息发生更新或者更换的时刻的信息。
例如，在第一更新时刻之前，小区#S的PCI与第一小区的PCI相同，小区#S的标识信息与第一小区的标识信息也相同，小区#S与第一小区之间距离较远，小区#S与第一小区不符合邻区关系，这不会产生问题。随着卫星设备的移动和覆盖区域的改变，小区#S与第一小区之间的距离可能拉近，小区#S与第一小区符合邻区关系，即：小区#S是第一小区的邻区。小区#S的标识信息与第一小区的标识信息相同，小区#S与第一小区又符合 邻区关系，则可能会出现图2所示的问题。
因此，第一小区对应的网络设备在小区#S成为第一小区的邻区之前向第一小区覆盖范围内的终端设备发送第一配置信息，从而让该第一小区覆盖范围内的终端设备知晓第一小区在第一更新时刻或者第一更新时刻之后使用的标识信息将会变成由第一标识更新信息确定的第一标识信息。这可以使第一小区的标识信息与小区#S的标识信息能够区分，从而避免第一小区与小区#S之间发生小区标识混淆或冲突。
一种可能的实现方式中，该第一标识信息包括PCI。例如，第一小区的PCI在第一更新时刻之前与小区#S的PCI相同，第一小区可以在第一更新时刻或者第一更新时刻之后使用一个更新后的PCI，从而可以与小区#S的PCI区分，这可以避免第一小区与小区#S之间发生PCI混淆或冲突。
一种可能的实现方式中，该第一标识信息包括频点。例如，第一小区的PCI与频点在第一更新时刻之前与小区#S的PCI与频点均相同，第一小区可以在第一更新时刻或者第一更新时刻之后使用一个更新后的频点，从而可以与小区#S的频点区分，从而避免第一小区与小区#S之间发生频点混淆或冲突。
一种可能的实现方式中，该第一标识信息包括极化方向。例如，第一小区的PCI、频点和极化方向在第一更新时刻之前与小区#S的PCI、频点和极化方向均相同，第一小区可以在第一更新时刻或者第一更新时刻之后使用一个更新后的极化方向，从而可以与小区#S的极化方向区分，从而避免第一小区与小区#S之间发生极化方向混淆或冲突。
示例性地，第一小区的PCI、频点和极化方向在第一更新时刻之前与小区#S的PCI、频点和极化方向均是相同的，则可以通过改变第一小区的PCI、频点和极化方向这三个参数中的至少一个参数，使其与小区#S区分。例如，第一小区的PCI在第一更新时刻之前与该小区#S的PCI是相同的，则可以通过改变第一小区的PCI，使其与该小区#S的PCI不同。例如，第一小区的PCI和极化方向在第一更新时刻之前与该小区#S的PCI和极化方向是相同的，则可以通过改变第一小区的极化方向或者PCI，使其与该小区#S的极化方向或者PCI不同。又例如，第一小区的PCI和频点在第一更新时刻之前与小区#S的PCI和频点是相同的，则可以通过改变第一小区的频点或者PCI，使其与小区#S区分。第一小区的PCI、频点和极化方向在第一更新时刻之前与小区#S的PCI、频点和极化方向均是相同的，则可以通过改变第一小区的频点和极化方向这两个参数中的至少一个参数，使其与小区#S区分。
第一小区的PCI、频点和极化方向与小区#S的PCI、频点和极化方向均相同时，可以同时改变上述三个参数中的一个参数、两个参数或者三个参数，本申请实施例不作限定。
第一小区的PCI与小区#S的PCI相同时，可以同时改变上述三个参数中的一个参数、两个参数或者三个参数，本申请实施例也不作限定。
第一更新时刻可以是前述的小区#S成为第一小区的邻区的时刻，也可以是前述的小区#S成为第一小区的邻区的时刻之前的一个时刻。当第一更新时刻是前述的小区#S成为第一小区的邻区的时刻，该第一标识更新信息用于确定第一小区在第一更新时刻或者在第一更新时刻之后使用的第一标识信息。或者说，第一通信装置从第一更新时刻起开始使用第一标识信息。当第一更新时刻是前述的小区#S成为第一小区的邻区的时刻之前的一个时刻，该第一标识更新信息可以用于确定第一小区在第一更新时刻或者第一更新时刻之后 使用的第一标识信息。或者说，第一通信装置从第一更新时刻或者第一更新时刻之后的某个时刻起开始使用第一标识信息。
该第一更新时刻之后可以理解为是在前述的小区#S成为第一小区的邻区的时刻之前或者等于前述的小区#S成为第一小区的邻区的时刻。
应理解，第一标识信息可以包括PCI，也可以包括频点，还可以包括极化方向，也可以包括频点和极化方向，也可以包括PCI、频点和极化方向，也可以包括其他的信息，本申请实施例不作限定。
第一标识更新信息可以是前述的第一标识信息本身，也可以是第一标识信息与第一小区在第一更新时刻之前使用的标识信息之间的差值。该差值可以是正值，也可以是负值。下文将对此做进一步的说明。
S320，第一通信装置根据第一配置信息在第一更新时刻或者第一更新时刻之后使用第一标识信息进行通信。
具体地，第一小区覆盖范围内的终端设备接收第一配置信息之后，可以根据该第一配置信息在第一更新时刻或者第一更新时刻之后使用第一标识信息进行相应的通信。下文将对此做进一步的说明。
当第一更新时刻是前述的小区#S成为第一小区的邻区的时刻，第一小区覆盖范围内的终端设备可以在第一更新时刻使用第一标识信息进行通信。当第一更新时刻是前述的小区#S成为第一小区的邻区的时刻之前的一个时刻，第一小区覆盖范围内的终端设备可以在第一更新时刻或者第一更新时刻之后使用第一标识信息进行通信。该第一更新时刻之后可以理解为是在前述的小区#S成为第一小区的邻区的时刻之前或者等于前述的小区#S成为第一小区的邻区的时刻。
一种可能的实现方式中，在图2中，终端向网络设备上报的测量结果可以包括小区的PCI、频点、极化方向中的至少一项，网络设备则可以基于该测量结果确定该终端要切换到的目标小区(target cell)，并触发终端由驻留小区切换到目标小区。
具体来说，源gNB根据切换原则确定该终端要切换到的目标小区。例如，可以选择信号最强的小区作为切换的目标小区。由于小区间的PCI、频点或极化方向中的至少一项不同，因此，源gNB根据PCI、频点或极化方向中的至少一项区分出具体的目标小区，从而不会产生冲突问题。
另外，源gNB向终端发送目标小区的标识信息可以包括PCI，可以包括PCI和频点，可以包括：PCI和极化方向，或者也可以包括：PCI、频点和极化方向，这样就可以避免终端对具有相同PCI的相邻小区产生混淆。
应理解，在本申请实施例中，第一小区的SSB和第一小区的邻区的SSB可以使用相同频点，第一小区覆盖范围内的终端设备与第一小区的邻区覆盖范围内的终端设备进行邻区测量也可以使用同频测量，在此做统一说明，后文将不再赘述。
通过在与第一小区的标识相同的小区成为第一小区的邻区这一时刻或者这一时刻之前更新第一小区的标识信息，网络设备就可以根据不同的小区的标识信息将第一小区和邻区进行区分，避免第一小区与邻区的小区标识发生冲突或混淆，进而避免因小区标识冲突或混淆造成的小区切换失败等问题。通过上述技术方案，本申请实施例也能够避免PCI mod N相同的邻区之间因小区标识发生冲突或者混淆而导致小区切换失败的问题。
下文将结合图4至图9对本申请实施例提供的其他通信方法进行描述。
为便于描述，在下文中，本申请实施例以邻区关系为一阶邻区关系为例进行描述，但也可以拓展至二阶邻区关系和多阶邻区关系，且二阶邻区关系和多阶邻区关系对应的技术方案与一阶邻区关系对应的技术方案类似，因此，二阶邻区关系和多阶邻区关系对应的技术方案可以参考一阶邻区关系对应的技术方案，故不再赘述。
图4是本申请实施例提供的一种通信方法的示意流程图。该方法包括：
S410，网络设备#A确定小区#A与小区#B符合一阶邻区关系的时刻#A。
小区#A与小区#B是两个PCI相同的小区。例如，小区#A的PCI为#100，小区#B的PCI也为#100。
应理解，小区#A与小区#B也可以是两个PCI mod N相同的小区。N可以等于30。当小区#A与小区#B是PCI mod 30相同的一阶邻区时，网络设备#A也需要改变小区#A的标识信息，从而避免小区#A与小区#B之间发生冲突。该描述也适用于下文，后文将不再赘述。
随着卫星设备的移动，小区#A与小区#B之间的距离可能拉近，小区#A与小区#B可以符合一阶邻区关系(见图2a)。小区#A与小区#B的PCI相同可能会产生如图2所示的问题。
应理解，网络设备#A可以根据卫星设备的星历信息预测NTN中邻区关系的时变特性，并根据该时变特性确定小区#A与小区#B符合一阶邻区关系的时刻#A。小区#A是网络设备#A所对应的其中一个小区。小区#B可以是网络设备#A所对应的其中一个小区，也可以不是网络设备#A所对应的其中一个小区。
S420，网络设备#A确定小区#A的更新后的PCI。
为避免小区#A与小区#B在符合一阶邻区关系时因具有相同PCI而产生一阶邻区PCI冲突的问题，网络设备#A需要更新小区#A的PCI，即确定小区#A的更新后的PCI。该更新后的PCI能够使得小区#A与小区#B在PCI方面区分开。该更新后的PCI是不同于小区#A的邻区的PCI。例如，网络设备#A可以基于与小区#A的邻区对应的网络设备进行信息交互来确定小区#A的更新后的PCI。
在一个可能的例子中，S420#A，网络设备#A确定小区#A的更新后的PCI与更新前的PCI之间的PCI差值。该PCI差值可以是正值，也可以是负值。下文将对其进行描述。
S430，网络设备#A向终端设备#A发送配置信息#A，该配置信息#A包括更新后的PCI和时刻#B。
相应地，终端设备#A接收网络设备#A发送的配置信息#A。终端设备#A处于小区#A的覆盖范围之内。
一个可能的实现中，网络设备#A向终端设备#A发送的配置信息#A可以是根据星历信息确定的。
例如，网络设备#A可以根据星历信息确定其各个小区的标识信息以及更新时间信息，从而确定配置信息#A。
又例如，地面网络管理单元/网关根据星历信息配置网络设备#A的各个小区的标识信息以及更新时间信息，并将该标识信息以及更新时间信息发送给网络设备#A，然后网络设 备#A将各个小区的标识信息以及更新时间信息发送给各个小区覆盖范围内的终端设备。更具体的，地面网络管理单元/网关可以根据卫星星座以及小区分布等信息确定配置信息#A，并将该配置信息#A发送给网络设备#A，进一步地，网络设备#A将该配置信息#A发送给终端设备#A。换言之，网络设备#A可以根据地面网络管理单元/网关向网络设备#A发送其根据星历信息确定的网络设备#A的各个小区的标识信息以及更新时间信息来确定配置信息#A。或者说，地面网络管理单元/网关根据卫星星座以及小区分布等信息确定配置信息#A，并将该配置信息#A发送给网络设备#A，网络设备#A向对应小区的覆盖范围内的终端设备发送第一小区(以及第一小区的邻区)的PCI以及时间信息。该描述也适用于下文的频点和极化方向的描述，后文将不再赘述。
一种可能的实现方式中，配置信息#A可以是一个PCI更新信息元素(PCI update information element)。PCI update information element包括：更新后的PCI和时刻#B。
应理解，时刻#B可以是时刻#A，也可以是时刻#A之前的一个时刻。时刻#B是用于表示小区#A的PCI发生变化的一个时刻。该小区#A的PCI可以是在时刻#A发生变化，也可以是早于时刻#A发生变化。
示例性的，PCI update information element的结构如表1所示：
表1PCI update information element
或者，PCI update information element的结构也可以如下所示：
其中，PCI_value用于表示更新后的PCI，例如，可以使用10比特表示。TimeInfo_UTC用于表示时刻#B，其是一个协调世界时(coordinated universal time，UTC)时间参数，例如，可以使用39比特表示。TimeInfo_UTC时间单位可以为10ms，从格里高利日历(gregorian calendar)日期1900年1月1日(1899年12月31日24：00或1900年1月1日00:00)开始计算。
一种可能的实现方式中，时刻#B与定时器(timer)对应。例如，网络设备#A向终端设备#A配置一个长度为10秒的定时器，那么终端设备#A接收到配置信息#A之后开启定时器，并在定时器失效后(即10秒后)可以使用更新后的PCI。通过使用定时器，本申请实施例可以准确地指示小区的标识信息的更新或者更换时刻。
一种可能的实现方式中，时刻#B还可以与格林尼治标准时间(greenwich mean time，GMT)对应。通过使用UTC或GMT时间，本申请实施例能够更准确地指示小区的标识信息的更新或者更换时刻。
应理解，UTC和GMT可以称为标准时间。该标准时间还可以包括其他类型的时间。时刻#B可以与标准时间对应，也可以与定时器对应。
在又一个可能的例子中，S430#A，网络设备#A向终端设备#A发送的配置信息#A包括PCI差值和时刻#B。该PCI差值是网络设备#A根据小区#A的更新后的PCI与更新前的PCI确定的。该PCI差值可以存在正负之分。例如，小区#A的更新后的PCI为100，更新前的PCI为90，则PCI差值为(+10)。终端设备根据90+10得到更新后的PCI为100。又例如，小区#A的更新后的PCI为90，更新前的PCI为100，则PCI差值为(-10)。终端设备根据100-10得到更新后的PCI为90。网络设备#A将该PCI差值发送给终端设备#A，终端设备#A基于该PCI差值确定小区#A的更新后的PCI。
应理解，第一标识更新信息包含更新后的PCI，可以使得终端设备直接获取第一小区更新后的PCI。通过指示更新后的PCI与第一小区在第一更新时刻前使用的PCI之间的PCI差值，能够节约信令开销。
一种可能的实现方式中，网络设备#A可以通过广播/组播的方式向小区#A覆盖范围内的终端设备#A发送配置信息#A。如此可以避免为了发送上述配置信息而对不同终端设备调度不同资源，从而可以节省调度资源的信令开销和降低系统调度复杂度。
S440，终端设备#A根据配置信息#A在时刻#B或者时刻#B之后使用更新后的PCI进行通信。
或者说，终端设备#A从时刻#B或者时刻#B起开始使用更新后的PCI进行通信。
时刻#B之后的时刻可以是早于时刻#A或者与时刻#A等同的，即：小区#A的PCI需要在时刻#A这一刻或者时刻#A之前完成更新或者更换。该描述同样适用于本申请实施例的后续内容，后文将不再强调这一点。
具体地，终端设备#A使用更新的PCI对网络设备#A的小区进行测量以及与网络设备#A间进行通信。网络设备#A也使用更新后的PCI与终端设备#A进行通信，以及使用更新后的PCI对应的系统序列与终端设备#A进行通信。该系统序列包括相应的导频(PSS、SSS、信道状态信息参考信号(channel state information reference signal，CSI-RS)、解调参考信号(demodulatin reference signal，DMRS)、探测参考信号(sounding reference signal，SRS)等)和扰码等。上述导频序列、扰码等可以根据小区的PCI生成。
一种可能的实现方式中，若配置信息#A包括PCI差值，终端设备#A根据该PCI差值与更新前的PCI确定小区#A的更新后的PCI。
图4所示的PCI可以理解为是图3所示的第一标识信息。图4所示的更新后的PCI或者PCI差值可以理解为是图3所示的第一标识更新信息。图4所示的时刻#B可以理解为是图3所示的第一更新时刻。图4所示的UTC、GMT和定时器可以理解为是图3所示的第一更新时刻信息。
在图3所示的技术方案中，网络设备#A可以基于预测确定小区#A的其他时刻对应的PCI，如此就能够通过一次配置信息就可以确定一段时间内的多个PCI，如此，就可以避免多次频繁发送配置信息，并可以节约信令资源。例如，小区#A的多个时段对应的PCI， 如表2a所示。小区#A的多个时刻对应的PCI，如表2b所示。
表2a小区#A的多个时段对应的PCI
表2b小区#A的多个时刻对应的PCI
在表2a中，小区#A在时刻#A之前与小区#B的PCI(均为100)相同，小区#B在时刻#A成为小区#A的一阶邻区。小区#A的PCI需要在时刻#A或者时刻#A之前发生更换或更新，由100更换或更新为90。小区#A在时刻#F之前与小区#D的PCI(均为90)相同，小区#D在时刻#F成为小区#A的一阶邻区。小区#A的PCI需要在时刻#F或者时刻#F之前发生更换或更新，由90更换或更新为120。小区#A在时刻#Z之前与小区#G的PCI(均为120)相同，小区#G在时刻#Z成为小区#A的一阶邻区。小区#A的PCI需要在时刻#Z或者时刻#Z之前发生更换或更新，由120更换或更新为130。
在表2b中，小区#A在时刻#A的PCI为90，在时刻#F的PCI为120，在时刻#Z的PCI是130。通过指示不同时刻对应的PCI，本申请实施例能够区分第一小区的PCI与邻区的PCI，可以避免小区标识相同的多个邻区之间发生冲突，进而避免因小区标识冲突或混淆而造成小区切换失败。
上述的表2a和表2b是两种示例性表达方式，本申请实施例不限定其他的表达形式。
应理解，配置信息#A可以包括一个更新后的PCI和更新时刻(见表1)，也可以包括多个更新后的PCI和更新时刻(见表2)。
网络设备#A可以将表2所示的内容作为配置信息#A发送给小区#A覆盖范围内的终端设备#A，并由该终端设备#A按照表2所示的时间信息进行PCI的更换或者更新。
作为一个实施例，网络设备#A向终端设备#A发送的配置信息#A可以是网络设备#A接收小区#A的邻区对应的网络设备发送的配置信息。下文将对此做进一步的说明。
作为另一个实施例，网络设备#A可以向小区#A的邻区对应的网络设备发送该配置信息#A，如此可以使得第一小区的邻区的覆盖范围内的终端设备可以使用更新后的标识信息对第一小区进行测量以及与第一小区对应的网络设备进行通信。下文将对此做进一步的说明。
应理解，步骤S410和步骤S420可以是同时进行的，也可以是分先后进行的。本申请实施例对此不作具体限定。
通过在与第一小区的PCI(或者PCI mod N)相同的小区成为第一小区的邻区这一时 刻或者这一时刻之前更换第一小区的PCI，本申请实施例就可以根据小区的PCI的不同将第一小区和该与第一小区的更新前的PCI相同的小区区分开，如此，便可以避免第一小区与邻区发生PCI混淆或冲突。
应理解，在图4所示的技术方案中，小区#A与小区#B的频点和/或极化方向可以相同，也可以不同，本申请实施例不限定。
应理解，网络设备#A可以理解为是前述的第二通信装置，终端设备#A可以理解为是前述的第一通信装置。
图5是对图4所示的技术方案的示例性的描述。
图5是本申请实施例提供的一种避免一阶邻区PCI冲突的示意图。在图5，小区#A是Cell A，小区#B是Cell E。Cell A和Cell E的PCI均是10。在时刻#A之前，Cell A和Cell E不符合一阶邻区关系。在时刻#A，Cell A和Cell E符合一阶邻区关系。Cell A对应的网络设备需要在时刻#A或者时刻#A之前更新PCI，且更新后的PCI与Cell B和Cell F的PCI均是不同的，例如，将Cell A的PCI的值从10改为6。在时刻#A，Cell A与Cell E符合一阶邻区关系，但是Cell A与Cell E的PCI不相同，从而避免了一阶邻区PCI冲突。
图4所示的技术方案也可以适用于小区#A与小区#B符合二阶邻区关系或者多阶邻区关系的场景，具体内容与上述内容一致，在此不再赘述。
图4所示的配置信息#A可以被包括在系统信息块(system information block，SIB)、其他系统消息(other system information，OSI)、主系统信息块(mater information block，MIB)等的广播信息中的至少一种，并由网络设备向终端设备广播或组播发送，如此可以避免为了发送上述信令而对不同终端设备调度不同资源，从而可以节省调度资源的信令开销和降低系统调度复杂度。
一种可能的实现方式中，网络设备在无线资源控制(radio resource control，RRC)建立连接阶段以及后续通信过程中向终端设备发送该配置信息#A时，网络设备可以通过单播/组播消息发送该配置信息#A，例如通过在RRC信令(例如，RRC建立(RRCsetup)消息、RRC重配信令(RRCReconfiguration)、RRC恢复信令(RRCResume)等)、下行控制信息(downlink control information，DCI)、组DCI、媒体接入控制(medium access control，MAC)控制元素(control element，CE)、定时提前命令(timing advance command，TAC)中的至少一项中携带配置信息#A，或者随数据传输或在单独分配的物理下行数据共享信道(physical downlink shared channel，PDSCH)承载中向终端设备单播或组播发送，如此可以不必等待广播消息的更新时延(广播消息按照一定周期进行更新)，可以及时向终端设备发送与驻留小区/邻区的PCI更新相关的消息，具有更强的时效性。
图6是本申请实施例提供的再一种通信方法的示意流程图。该方法包括：
S610，同前述步骤S410。
S620，网络设备#A确定小区#A的更新后的频点。
为避免小区#A与小区#B在符合一阶邻区关系时因具有相同PCI而产生一阶邻区PCI冲突的问题，网络设备#A可以更新小区#A的频点，即确定小区#A的更新后的频点。该更新后的频点能够使得小区#A与小区#B在频点方面区分。
应理解，小区#A的更新后的频点可以与小区#A的其他PCI不同的邻区的频点相同，也可以不同。
在一个可能的例子中，S620#A，网络设备#A确定小区#A的更新后的频点与更新前的频点之间的频点差值。该频点差值可以是正值，也可以是负值。下文将对其进行描述。
S630，网络设备#A向终端设备#A发送配置信息#B，配置信息#B包括更新后的频点与时刻#B。
相应地，终端设备#A接收网络设备#A发送的配置信息#B。终端设备#A处于小区#A的覆盖范围之内。
一种可能的实现方式中，配置信息#B可以是一个频率更新信息元素(frequency update information element)。frequency update information element包括：更新后的频点和时刻#B。
应理解，时刻#B可以是时刻#A，也可以是时刻#A之前的一个时刻。时刻#B是用于表示小区#A的频点发生变化的一个时刻。该一个时刻可以是时刻#A，也可以早于时刻#A。
示例性地，frequency update information element的结构如表3所示：
表3Frequency update information element
或者，frequency update information element的结构也可以如下所示：
其中，Frequency_value用于表示更新后的频点。TimeInfo_UTC用于表示时刻#B。TimeInfo_UTC可以使用39比特表示。关于时刻#B的具体描述可以参见前述内容，在此不再赘述。
在又一个可能的例子中，S630#A，网络设备#A向终端设备#A发送的配置信息#B包括频点差值和时刻#B。该频点差值是网络设备#A根据小区#A的更新后的频点与更新前的频点确定的。例如，小区#A的更新后的频点为100GHz，更新前的频点为90GHz，则频点差值为(+10)GHz，终端设备根据90MHz+10MHz获得更新后的频点为100MHz。又例如，小区#A的更新后的频点为90GHz，更新前的频点为100GHz，则频点差值为(-10)GHz，终端根据100MHz-10MHz获得更新后的频点为90MHz。该频点差值存在正负之分。网络设备#A可以将该频点差值发送给终端设备#A，终端设备#A然后基于该频点差值确定小区#A的更新后的频点。通过配置频点差值，可以节省信令开销。
通过在配置信息#B中直接携带更新后的频点，本申请实施例能够使得终端设备直接获取第一小区更新后的频点。通过在配置信息#B中携带频点差值，本申请实施例能够节约信令开销。
该网络设备#A可以通过广播/组播的方式向小区#A的覆盖范围内的终端设备#A发送该配置信息#B。如此可以避免为了发送上述配置信息而对不同终端设备调度不同资源，从而可以节省调度资源的信令开销和降低系统调度复杂度。
S640，终端设备#A根据配置信息#B在时刻#B或者时刻#B之后使用更新后的频点进行通信。
或者说，终端设备#A从时刻#B或者时刻#B起开始使用更新后的频点进行通信。
具体地，终端设备#A接收配置信息#B之后，使用更新后的频点从网络设备#A获取同步信号、MIB和SIB等消息，并与网络设备#A进行通信。网络设备#A也使用更新后的频点发送MIB和SIB等消息。
一种可能的实现方式中，若配置信息#B包括频点差值，终端设备#A需要根据该频点差值与更新前的频点确定小区#A的更新后的频点。
图6所示的频点可以理解为是图3所示的第一标识信息。图6所示的更新后的频点或者频点差值可以理解为是图3所示的第一标识更新信息。图6所示的时刻#B可以理解为是图3所示的第一更新时刻。
在图6所示的技术方案中，网络设备#A可以基于预测确定小区#A的其他时刻对应的频点，如此就能够通过一次配置信息就可以确定一段时间内的多个频点，如此，就可以避免多次频繁发送配置信息，并可以节约信令资源。例如，小区#A的多个时段对应的频点，如表4a所示。小区#A的多个时刻对应的频点，如表4b所示。
表4a小区#A的多个时段对应的频点
表4b小区#A的多个时刻对应的频点
在表4a中，小区#A在时刻#A之前与小区#B的PCI和频点相同(均为频点1)，小区#B在时刻#A成为小区#A的一阶邻区。小区#A的频点需要在时刻#A或者时刻#A之前发生切换，由频点1切换为频点2。小区#A在时刻#F之前与小区#D的PCI和频点相同(均为频点2)，小区#D在时刻#F成为小区#A的一阶邻区。小区#A的频点需要在时刻#F或者时刻#F之前发生更换或更新，由频点2更换或更新为频点3。小区#A在时刻#Z之前与 小区#G的PCI和频点相同(均为频点3)，小区#G在时刻#Z成为小区#A的一阶邻区。小区#A的频点需要在时刻#Z或者时刻#Z之前发生更换或更新，由频点3更换或更新为频点4。
在表4b中，小区#A在时刻#A的频点为频点2，在时刻#F的频点为频点3，在时刻#Z的频点是频点4。通过指示不同时刻对应的频点，可以区分第一小区的频点与邻区的频点，便可以避免小区标识相同的多个邻区之间发生冲突，进而避免因小区标识冲突或混淆而造成小区切换失败。
上述的表4a和表4b是两种示例性表达方式，本申请实施例不限定其他的表达形式。
应理解，配置信息#B可以包括一个更新后的频点和更新时刻(见表3)，也可以包括多个更新后的频点和更新时刻(见表4)。
网络设备#A可以将表4所示的内容作为配置信息#B发送给小区#A覆盖范围内的终端设备#A，并由该终端设备#A按照表4所示的时间进行频点的更新或者更换。
在一种可能的实现方式中，网络设备#A向终端设备#A发送的配置信息#B可以是网络设备#A接收小区#A的邻区对应的网络设备发送的配置信息。下文将对此做进一步的说明。
在一种可能的实现方式中，网络设备#A可以向小区#A的邻区对应的网络设备发送该配置信息#B，如此可以让处于邻区覆盖范围内的终端设备能够根据小区#A更新后的频点对小区#A测量以及与小区#A的网络设备通信。下文将对此做进一步的说明。
在图2中，终端向网络设备上报的测量结果可以包括小区的PCI和频点，网络设备则可以基于该测量结果确定该终端要切换到的目标小区，并触发终端由驻留小区切换到目标小区。
具体来说，源gNB根据切换原则确定该终端要切换到的目标小区。例如，可以选择信号最强的小区作为切换的目标小区。由于小区间的频点不同，因此，源gNB根据频点区分出具体的目标小区，从而不会产生冲突问题。
另外，源gNB向终端发送目标小区的标识信息可以包括PCI和频点，这样就可以避免终端对具有相同PCI的相邻小区产生混淆。
通过在与第一小区的PCI(或者PCI mod N)相同的小区成为第一小区的邻区这一时刻或者这一时刻之前更换第一小区的频点，本申请实施例就可以根据小区的频点的不同将第一小区和该与第一小区的PCI相同的小区区分，如此，便可以避免小区标识相同的多个邻区之间发生冲突，进而避免因小区标识冲突或混淆而造成小区切换失败。
应理解，在图6所示的技术方案中，小区#A与小区#B的极化方向可以相同，也可以不同，本申请实施例不限定。
图7是对图6所示的技术方案的示例性的描述。
图7是本申请实施例提供的另一种避免一阶邻区PCI冲突的示意图。在图7中，小区#A是Cell A，小区#B是Cell E，Cell A和Cell E的PCI均是10，Cell A和Cell E的频点均是频点1。在时刻#A之前，Cell A和Cell E不符合一阶邻区关系。在时刻#A，Cell A和Cell E符合一阶邻区关系。Cell A对应的网络设备需要在时刻#A或者时刻#A之前将Cell A的频点从频点1改为频点2。在时刻#A，Cell A与Cell E符合一阶邻区关系，但是 Cell A与Cell E的频点不相同，从而避免了一阶邻区PCI冲突。
图6所示的技术方案也可以适用于小区#A与小区#B符合二阶邻区关系或者多阶邻区关系的场景，具体内容与上述内容一致，在此不再赘述。
一种可能的实现方式中，图6所示的配置信息#B可以由网络设备向终端设备广播或组播发送，例如，被包括在SIB、OSI、MIB等的广播信息中的至少一种，如此可以避免为了发送上述信令而对不同终端设备调度不同资源，从而可以节省调度资源的信令开销和降低系统调度复杂度。
一种可能的实现中，网络设备在RRC建立连接阶段以及后续通信过程中向终端设备发送该配置信息#B时，网络设备可以通过单播/组播消息发送该配置信息#B，例如通过在RRC信令(例如，RRC建立消息、RRC重配信令、RRC恢复信令等)、DCI、组DCI、MAC CE、TAC中的至少一项中携带配置信息#B，或者随数据传输或在单独分配的PDSCH承载中向终端设备单播或组播发送，如此可以不必等待广播消息的更新时延(广播消息按照一定周期进行更新)，可以及时向终端设备发送与驻留小区/邻区的频点更新相关的消息，具有更强的时效性。
图8是本申请实施例提供的另一种通信方法的示意流程图。该方法包括：
S810，同前述步骤S410。
S820，网络设备#A确定小区#A的更新后的极化方向。
为避免小区#A与小区#B在符合一阶邻区关系时因具有相同PCI而产生一阶邻区PCI冲突的问题，该网络设备#A可以更新小区#A的极化方向，即确定小区#A的更新后的极化方向。该更新后的极化方向能够使得小区#A与小区#B在极化方向方面区分。
S830，网络设备#A向终端设备#A发送配置信息#C，该配置信息#C包括更新后的极化方向和时刻#B。
相应地，终端设备#A接收该网络设备#A发送的配置信息#C。终端设备#A处于小区#A的覆盖范围之内。
一种可能的实现方式中，配置信息#C可以是一个极化方向更新信息元素(polarization direction update information element)。该polarization direction update information element包括：更新后的极化方向和时刻#B。
应理解，时刻#B可以是时刻#A，也可以是时刻#A之前的一个时刻。时刻#B是用于表示小区#A的极化方向发生变化的一个时刻。该小区#A的极化方向可以是在时刻#A发生变化，也可以是早于时刻#A发生变化。
示例性的，polarization direction update information element的结构如表5所示：
表5 polarization direction update information element
或者，polarization direction update information element的结构也可以是如下所示：

其中，Polarization direction_value用于表示更新后的极化方向，可以使用至少一个比特表示。例如，使用一个比特，“1”用于表示左旋方向，“0”用于表示右旋方向；或者，“1”用于表示右旋方向，“0”用于表示左旋方向。例如，使用两个比特，“11”用于表示左旋方向，“00”用于表示右旋方向；或者，“10”用于表示右旋方向，“01”用于表示左旋方向。TimeInfo_UTC用于表示时刻#B。关于时刻#B的描述可以参见前述内容，在此不再赘述。
通过在配置信息#C中直接携带更新后的极化方向，本申请实施例能够使得终端设备直接获取第一小区更新后的极化方向。
一个可能的实现方式，该配置信息#C包括指示比特，该指示比特用于指示终端设备更新第一小区的极化方向。该指示比特可以包括一个或多个比特。例如，比特“1”用于表示更新第一小区的极化方向，或者，比特“0”用于表示不更新第一小区的极化方向。如此，可以节约信令开销。
作为一个可能的实现方式，该配置信息#C包括更新时间信息，终端设备在接收到该配置信息#C后就会默认更新第一小区的极化方向。如此，可以节约信令开销。
该网络设备#A可以通过广播/组播/单独发送的方式向小区#A的覆盖范围内的终端设备#A发送该配置信息#C。如此可以避免为了发送上述配置信息而对不同终端设备调度不同资源，从而可以节省调度资源的信令开销和降低系统调度复杂度。
S840，终端设备#A根据配置信息#C在时刻#B或者时刻#B之后使用更新后的极化方向进行通信。
或者说，终端设备#A从时刻#B或者时刻#B起开始使用更新后的极化方向进行通信。
具体地，终端设备#A使用更新的极化方向对网络设备#A的小区进行测量以及与网络设备A间进行通信。
图8所示的极化方向可以理解为是图3所示的第一标识信息。图8所示的更新后的极化方向可以理解为是图3所示的第一标识更新信息。图8所示的时刻#B可以理解为是图3所示的第一更新时刻。
在图8所示的技术方案中，网络设备#A可以基于预测确定小区#A的其他时刻对应的极化方向，如此就能够通过一次配置信息就可以确定一段时间内的多个极化方向，如此，就可以避免多次频繁发送配置信息，并可以节约信令资源。例如，小区#A的多个时段对应的极化方向，如表6a所示。小区#A的多个时刻对应的极化方向，如表6b所示。其中，小区#B的PCI、小区#D的PCI、小区#G的PCI和小区#A的PCI均相同。
表6a小区#A的多个时段对应的极化方向

表6b小区#A的多个时刻对应的极化方向
在表6a中，小区#A在时刻#A之前与小区#B的极化方向(均为左旋方向)相同，小区#B在时刻#A成为小区#A的一阶邻区，小区#A的极化方向需要在时刻#A或者时刻#A之前发生更换或更新，由左旋方向更换或更新为右旋方向。小区#A在时刻#A～时刻#F之间与小区#D的极化方向(均为右旋方向)相同，小区#D在时刻#F成为小区#A的一阶邻区，小区#A的极化方向需要在时刻#F或者时刻#F之前发生更换或更新，由右旋方向更换或更新为左旋方向。小区#A在时刻#F～时刻#Z之间与小区#G的极化方向(均为左旋方向)相同，小区#G在时刻#Z成为小区#A的一阶邻区，因此，小区#A的极化方向需要在时刻#Z或者时刻#Z之前发生更换或更新，由左旋方向更换或更新为右旋方向。
在表6b中，小区#A在时刻#A的极化方向为右旋方向，在时刻#F的极化方向为左旋方向，在时刻#Z的极化方向是右旋方向。通过指示不同时刻对应的极化方向，本申请实施例能够使得第一小区的极化方向与邻区的极化方向区分，便可以避免小区标识相同的多个邻区之间发生冲突，进而避免因小区标识冲突或混淆而造成小区切换失败。
上述的表6a和表6b是两种示例性表达方式，本申请实施例不限定其他的表达形式。
应理解，配置信息#C可以包括一个更新后的极化方向和更新时刻(见表5)，也可以包括多个更新后的极化方向和更新时刻(见表6)。
网络设备#A可以将表6所示的内容发送给小区#A覆盖范围内的终端设备，并由该终端设备按照表6所示的时间信息进行极化方向的更新或者更换。
在一种可能的实现中，网络设备#A向终端设备#A发送的配置信息#C可以是网络设备#A接收小区#A的邻区对应的网络设备发送的配置信息。下文将对此做进一步的说明。
在一种可能的实现中，网络设备#A可以向小区#A的邻区对应的网络设备发送该配置信息#C，如此可以让处于邻区覆盖范围内的终端设备能够根据小区#A更新后的极化方向对小区#A测量以及与小区#A的网络设备通信。下文将对此做进一步的说明。
应理解，在图8所示的技术方案中，小区#A与小区#B的频点可以相同，也可以不同，本申请实施例不限定。
应理解，图8所示的配置信息#C可以被包括在SIB、OSI、MIB等的广播信息中的至少一种，由网络设备向终端设备广播或组播发送，如此可以避免为了发送上述信令而对不同终端设备调度不同资源，从而可以节省调度资源的信令开销和降低系统调度复杂度。
一种可能的实现方式中，网络设备在RRC建立连接阶段以及后续通信过程中向终端 设备发送该配置信息#C时，网络设备可以通过单播/组播消息发送该配置信息#C，例如通过在RRC信令、DCI、组DCI、MAC CE、TAC中的至少一项中携带配置信息#C，或者随数据传输或在单独分配的PDSCH承载中向终端设备单播或组播发送，如此可以不必等待广播消息的更新时延(广播消息按照一定周期进行更新)，可以及时向终端设备发送与驻留小区/邻区的极化方向更新相关的消息，具有更强的时效性。
一种可能的实现方式中，在图2中，终端向网络设备上报的测量结果可以包括小区的PCI和极化方向，网络设备则可以基于该测量结果确定该终端要切换到的目标小区，并触发终端由驻留小区切换到目标小区。
具体来说，源gNB根据切换原则确定该终端要切换到的目标小区。例如，可以选择信号最强的小区作为切换的目标小区。由于小区间的极化方向不同，因此，源gNB根据极化方向区分出具体的目标小区，从而不会产生冲突问题。
另外，源gNB向终端发送目标小区的标识信息可以包括PCI和极化方向，这样就可以避免终端对具有相同PCI的相邻小区产生混淆。
通过在与第一小区的PCI(或者PCI mod N)相同的小区成为第一小区的邻区这一时刻或者这一时刻之前更换第一小区的极化方向，本申请实施例就可以根据小区的极化方向的不同将第一小区和该与第一小区的PCI相同的小区区分，如此，便可以避免小区标识相同的多个邻区之间发生冲突，进而避免因小区标识冲突或混淆而造成小区切换失败。
在本申请实施例中，图4、图6和图8所示的技术方案之间可以互相组成新的技术方案。
示例性地，网络设备#A向小区#A发送的配置信息可以包括更新后的PCI和频点，也可以包括更新后的PCI和极化方向，也可以包括更新后的极化方向和频点。也可以包括更新后的PCI、频点和极化方向。具体内容可以参见前述描述，在此不再赘述。
图9是本申请实施例提供的又一种通信方法的示意流程图。该方法包括：
S910，网络设备#A向网络设备#B发送配置信息#A。
相应地，网络设备#B接收网络设备#A发送的配置信息#A。
具体地，网络设备#A在确定更新网络设备#A的小区#A的PCI之后，向小区#A的邻区对应的网络设备发送该配置信息#A。例如，网络设备#B对应的一个小区(如小区#C)是小区#A的一个邻区，网络设备#B会获取该配置信息#A。
应理解，网络设备#B可以理解为是第三通信装置，网络设备#A可以理解为是第二通信装置。
S920，网络设备#B向终端设备#B发送配置信息#A1。
相应地，终端设备#B接收网络设备#B发送的配置信息#A1。
应理解，网络设备#B向终端设备#B发送的配置信息#A1可以是配置信息#A，也可以基于配置信息#A增加一些信息得到的配置信息。例如，该新增的信息可以是小区#A更新前的PCI或者发生PCI更改的小区的小区标识(cell identity)。
应理解，终端设备#B处于小区#C的覆盖范围之内。小区#C是小区#A的一个邻区，网络设备#B为对应该小区#C的网络设备。
示例性地，该配置信息#A1是邻区PCI更新信息元素(neighbour PCI update information  element)。该neighbour PCI update information element的结构如表7所示：
表7neighbour PCI update information element
或者，neighbour PCI update information element的结构也可以是如下所示：
其中，PCI_value_old用于表示更新前的PCI值，例如，可以使用10比特来表示。PCI_value_new用于表示更新后的PCI值，例如，可以使用10比特来表示。终端设备#B接收到该配置信息#A1之后，可以获取的信息为：PCI为PCI_value_old的小区在时间TimeInfo_UTC之后将PCI更新到PCI_value_new。
一种可能的实现中，该配置信息#A1可以包括为小区标识(cell identity)、更新后的PCI和更新时刻信息。该cell identity用于表示PCI更新/切换的小区，例如，可以使用36比特来表示。该结构可以如下所示：
小区标识可以由基站标识和小区标号组成。例如，NR通信系统中的小区标识是由gNodeB ID和小区标号(cell ID)组成，小区标识的长度为36比特。在NR通信系统中，小区标识最大支持的小区数量为6.87e10。又例如，在通用移动通信系统演进陆地无线接入网络(evolution universal mobile telecommunications system terrestrial radio access network， E-UTRAN)通信系统中的小区标识是由eNodeB ID和小区标号组成，小区标识的长度为28比特。因此，在E-UTRAN通信系统中，小区标识最大支持的小区数量为2.68e8。每个小区都有对应的小区标号，该小区标号的最大长度为14比特，其最大支持的不重复小区数量为16384。
应理解，cell identity可以被包含在全球小区识别码(cell global identifier，CGI)信息中。全球小区标识包括移动国家码(mobile country code，Mcc)、移动网络码(mobile network code，Mnc)、基站标识、小区标号。例如，在NR通信系统中，基站标识为gNodeB ID。在E-UTRAN通信系统，基站标识为eNodeB ID。CGI的长度为60比特，其最大支持的数量为1.529e18。
通过以小区标识来区分小区，如此，本申请实施例可以使得网络设备#B对应的小区的覆盖范围内的终端设备可以确定发生PCI更新的小区是哪个小区，可以避免混淆。
终端设备#B可以通过SIB消息读取小区#A的CGI以及cell identity。因此，可以使用CGI替代Cell Identity，或者使用gNB ID或Cell ID替代Cell Identity。其中，eNB和gNB可以是4G系统的实体，也可以是5G系统的实体，或者，也可以是未来通信系统的实体。
S930，终端设备#B根据配置信息#A1在时刻#B或者时刻#B之后使用更新后的PCI进行通信。
具体地，终端设备#B使用更新的PCI对网络设备#A的小区进行测量以及与网络设备#A间进行通信。
图9所示的技术方案中，该配置信息#A1中的时刻信息可以是标准时间信息，也可以是定时器信息。若该时刻信息是定时器信息时，网络设备#B可以根据网络设备#A发送的定时器信息确定向小区#C发送的定时器的长度。
一种可能的实现方式，网络设备#A向小区#A覆盖范围内的终端发送的配置信息中的定时器的长度是长于网络设备#B向小区#C覆盖范围内的终端发送的配置信息中的定时器的长度的。网络设备#B可以根据网络设备#A发送的配置信息#A中定时器的长度和网络设备#A与网络设备#B之间的传输时延确定配置信息#A1中定时器的长度，如此，可以使网络设备#B对应的小区的覆盖范围内的终端设备与网络设备#A对应的第一小区的覆盖范围内的终端设备同步更新所属小区的标识信息。若该时刻信息是标准时间信息时，网络设备#A向小区#A发送的配置信息中的标准时间和网络设备#B向小区#C发送的配置信息中的标准时间是相同的。
通过上述技术方案，本申请实施例能够使得第一小区的邻区的覆盖范围内的终端设备可以使用更新后的标识信息对第一小区进行测量以及与第一小区对应的网络设备进行通信。
应理解，网络设备#A除了向网络设备#B发送的是配置信息#A，还可以向网络设备#B发送配置信息#B和配置信息#C，具体方案与图9所示的方案基本一致，在此不再赘述。
示例性地，网络设备#B接收网络设备#A发送的配置信息#B时，网络设备#B向终端设备#B发送配置信息#B1。示例性的，配置信息#B1可以是邻区频点更新信息元素(neighbour frequency update information element)。该neighbour frequency update information element的结构如表8所示：
表8 neighbourfrequency update information element
或者，neighbour frequency update information element的结构也可以是如下所示：
其中，cell identity用于表示频点更新/切换小区的小区标识，例如，可以使用36比特表示。Frequency_info_new用于表示小区更新后的频点信息。终端设备#B接收到该配置信息#B1之后，可以获取的信息为：小区标识为表8所示的CellIdentity的小区在时间TimeInfo_UTC之后将频点更新到Frequency_info_new。关于cell identity的描述可以参考前述描述，在此不再赘述。
一种可能的实现方式中，网络设备#B除了可以接收网络设备#A发送的由网络设备#A确定的配置信息之外，网络设备#B也可以向网络设备#A发送由网络设备#B确定的小区#C的配置信息，并由网络设备#A将其接收到的配置信息发送给小区#A的覆盖范围内的终端设备。具体内容可以参见前述内容，在此不再赘述。
一种可能的实现方式中，网络设备#A对应多个小区时，网络设备#A可以将其多个小区的PCI信息发送给网络设备#B。例如，示例性地，如表9a和表9b所示：
表9a网络设备#A对应的多个小区的多个时段对应的PCI
表9b网络设备#A对应的多个小区的多个时刻对应的PCI

应理解，表9a和表9b是两种示例性的表达方式，本申请实施例不限定其他的表达方式。
网络设备#B接收到上述信息之后，将其发送给网络设备#B所对应的小区的覆盖范围内的终端设备，并由网络设备#B所对应的小区的覆盖范围内的终端设备进行更新，从而进行对应的通信。
一种可能的实现方式中，网络设备#A也可以将其多个小区的频点信息发送给网络设备#B。示例性地，可见表10a和表10b：
表10a网络设备#A对应的多个小区的多个时段对应的频点
表10b网络设备#A对应的多个小区的多个时刻对应的频点
应理解，表10a和表10b是两种示例性的表达方式，本申请实施例不限定其他的表达方式。
网络设备#B接收到上述信息之后，将其发送给网络设备#B所对应的小区的覆盖范围内的终端设备，并由网络设备#B所对应的小区的覆盖范围内的终端设备进行更新，从而进行对应的通信。
网络设备#A也可以将其多个小区的极化方向信息发送给网络设备#B。示例性地，可见表11a和表11b：
表11a网络设备#A对应的多个小区的多个时段对应的极化方向

表11b网络设备#A对应的多个小区的多个时刻对应的极化方向
应理解，表11a和表11b是两种示例性的表达方式，本申请实施例不限定其他的表达方式。
网络设备#B接收到上述信息之后，将其发送给网络设备#B所对应的小区的覆盖范围内的终端设备，并由网络设备#B所对应的小区的覆盖范围内的终端设备进行更新，从而进行对应的通信。
上述图4至图9所示的技术方案之间也可以互相组合成新的技术方案，本申请实施例不作具体限定。
