Description

一种通信方法及装置
本申请要求于2020年09月10日提交中国专利局、申请号为202010949394.0、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
第五代移动通信系统(5th generation wireless systems，5G)中，用户设备(User Equipment，UE)可处于三种工作状态中的一种，分别为RRC连接态(connected)、RRC空闲态(idle)、RRC非激活态(inactive)，网络设备可以向处于连接态、非激活态、空闲态的UE发送寻呼消息(paging)，以实现网络设备与UE之间的通信。
部分带宽(Bandwidth part，BWP)是5G新空口(New Radio,NR)标准提出的新概念，是网络侧配置给UE的一段连续的带宽资源，利用BWP可实现网络侧和UE侧的灵活传输带宽，BWP大致可分为两类：初始BWP(Initial BWP)和专用BWP(Dedicated BWP)，分别对应UE在不同工作状态时使用，现有技术中，基站可以在初始BWP或专用BWP上配置用于寻呼的配置信息，UE通过接收此配置信息，获知发送寻呼的物理下行控制信道(Physical Downlink Control Channel，PDCCH)，进而获取监听寻呼的位置，实现寻呼消息的接收。
然而，由于UE之间的差异性，不同的UE所支持的BWP可能不同，网络设备为了使UE设备接收到寻呼消息，需要同时在多个BWP位置同时进行寻呼，导致了寻呼资源浪费，影响寻呼效率的问题。
发明内容
本申请的目的在于提供一种通信方法及装置。用于解决解决寻呼资源浪费，影响寻呼效率的问题。
第一方面，本申请公开了一种通信方法，应用于网络设备，包括：接收第一能力信息，第一能力信息用于指示第一终端设备支持的部分带宽；根据第一能力信息，在目标部分带宽上发送第一寻呼消息。
基于上述技术内容，网络设备通过接收第一能力信息，从而确定第一终端设备支持的目标部分带宽，并向目标部分带宽上发送第一寻呼消息，其中，部分带宽用于承载寻呼或其他消息，由于目标部分带宽是与该第一终端设备支持的部分带宽相匹配，在该目标部分带宽发送第一寻呼消息，可以减少第一终端设备在其他部分带宽上接收寻呼消息，减少资源开销，提高了寻呼效率。
在一种可能的实现方式中，第一能力信息可以来自该第一终端设备。第一终端设备将 自身所支持的部分带宽信息作为第一能力信息上报给网络设备，可选地，第一能力信息可以承载在UE能力请求信息(UECapabilityInformation)消息或其他无线资源控制(Radio Resource Control，RRC)消息中，由第一终端设备发送给网络设备，其中，网络设备可以将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为基站。
在一种可能的实现方式中，第一能力信息可以来自核心网设备。可选地，核心网设备可以从应用服务器(APP server)获得第一能力信息，获取方式包括：获取第一终端设备的第一能力信息或获取多个终端设备的第一能力信息，多个终端设备包括第一终端设备。核心网设备将第一能力信息发送给网络设备。其中，核心网设备可以是会话管理功能(Session Management Function，SMF)网元或接入和移动性管理功能(Access and Mobility Management Function，AMF)网元。

具体实施方式
本申请实施例应用于第五代移动通信网络(5th-generation，5G)通信系统或未来可能出现的其他系统，还可以应用于其他通信系统，例如：无线局域网通信(wireless local area network，WLAN)系统，全球移动通信(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、等等。
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。需要说明的是，当本申请实施例的方案应用于5G系统、或者现有的系统、或未来可能出现的其他系统时，网络设备和终端设备的名称可能发生变化，但这并不影响本申请实施例方案的实施。
1)无线资源控制(Radio Resource Control，RRC)连接状态，在5G系统中，RRC连接状态包括RRC连接态(connected)、RRC空闲态(idle)、RRC非激活态(inactive)，当UE开机并未与无线网络建立连接时，UE处于RRC空闲态，处于RRC空闲态的UE不存在RRC连接，此时UE进行小区选择和重选，监听寻呼信道，跟踪区更新；当UE与无线网络连接，进行数据接收或发送时，UE处于RRC连接态；RRC非激活态是5G新增的一种RRC状态，处于RRC非激活态的UE，可以快速恢复至RRC连接态。
2)部分带宽(Bandwidth part，BWP)，5G-NR标准中提出的新的概念，是网络侧配置给UE的一段连续的带宽资源，可实现网络侧和UE侧灵活传输带宽。在系统的工作带宽(Carrier bandwidth)中，BWP是工作带宽的一个子集。如图1所示，在NR中BWP可以大致分为两类，即Initial BWP和Dedicated BWP。其中，Initial BWP是UE处于RRC空闲态时，在初始接入阶段使用的BWP；Dedicated BWP是UE进入RRC连接态后配置的BWP，协议规定，1个UE最多可以通过RRC信令配置4个Dedicated BWP，但同一时刻，1个UE只能有1个Dedicated BWP处于激活，即1个UE同时只能激活使用1个BWP，其中，第一个激活的BWP(First Active BWP)由RRC指示。通过不同类型的BWP，承载不同连接状态下的用于寻呼的下行控制信息(Downlink Control Information，DCI)，实现网络侧和UE侧之间的信息传输。

4)网络设备：可以是无线网络中的设备，例如网络设备可以为将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为基站。目前，一些RAN设备的举例为：5G通信系统中的新一代基站(generation Node B，gNodeB)、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)、家庭基站(例如，home evolved Node B，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wi-Fi)接入点(access point，AP)等。另外，在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。此外，在其它可能的情况下，网络设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请实施例中，为终端设备提供无线通信功能的装置称为网络设备。

图3为本申请实施例提供的一种应用场景图，如图3，网络设备例如为基站，基站向终端设备发送BWP配置，从而使基站与终端设备之间能够通过BWP进行数据的传输。在5G当前储备的方案中，基站可以在initial BWP和/或active BWP上配置用于寻呼的控制资源集(Control-resource set，CORESET)、搜索空间(search space)配置，终端设备通过此配置获知发送寻呼消息的时频资源位置(e.g.PDCCH)，然后通过预获取的参数计算寻呼帧(Paging Frame，PF)、寻呼时机(Paging Occasion，PO)，在PF、PO对应的位置监听寻呼消息，进而获取基站发送的寻呼消息。
在5G-NR协议中引入多播(Multicast)传输后，为了寻呼对多播业务感兴趣的终端设备或在多播组中的终端设备(以下简称“多播寻呼”)，网络设备设计了多播BWP，多播BWP是指用于传输多播业务的BWP，可以是由网络设备配置的。在本申请中，多播BWP有以下两种可能的实现方式，在一种可能的实现方式中，多播BWP包括扩展initial BWP或者扩展initial BWP中的一部分，图3A为本申请实施例提供的一种扩展initial BWP用于多播寻呼的示意图，如图3A所示，通过在原有的initial BWP的基础上，对initial BWP在频域上进行扩展，形成扩展initial BWP，将扩展出来的频带作为多播BWP，其中，对initial BWP在频域上进行扩展的方式有多种，例如，原有的initial BWP对应的频带为a赫兹(Hz)～bHz，将原有的initial BWP对应的频带扩展为aHz～cHz，其中，c大于b。此时，bHz～cHz频带对应的BWP为多播BWP，该多播BWP与扩展initial BWP相互重叠。再例如，原有的initial BWP对应的频带为aHz～bHz，将原有的initial BWP对应的频带扩展为dHz～bHz，其中，d小于a。还例如，原有的initial BWP对应的频带为aHz～bHz，将原有的initial BWP对应的频带扩展为dHz～cHz，其中，c大于b，且d小于a。
在另一种可能的实现方式中，多播BWP是通过引入独立多播BWP实现的，图3B为本申请实施例提供的一种独立多播BWP用于多播寻呼的示意图，如图3B所示，通过独立多播BWP实现多播BWP的方式与通过扩展initial BWP实现多播BWP的方式不同，独立多播BWP在频域上与initial BWP没有重叠部分，相互独立，例如，initial BWP对应的频带为aHz～bHz，独立多播BWP对应的频带为cHz～dHz，其中，a<b<c<d。此时，cHz～dHz频带对应的BWP即为独立多播BWP，独立多播BWP与对应频带为aHz～bHz的initial BWP之间不相互重叠。需要说明的是，独立多播BWP是为了将两种BWP区分阐述而在本申请中进行的简称，其概念与扩展initial BWP是相对的，并不限定独立多播BWP与其他专用 BWP没有重叠。
然而，由于不同的终端设备所支持的BWP可能不同，当网络设备想要寻呼某个UE时，网络设备无法确定UE接收寻呼的位置是在initial BWP还是多播BWP，为了能寻呼到UE，网络设备可能在两个BWP的寻呼位置都进行寻呼，导致寻呼资源的浪费。
为解决上述问题，本申请实施例提供了一种通信方法，通过终端设备的第一能力信息确定终端设备所支持的目标部分带宽，进而，实现终端设备与网络设置在目标部分带宽上的寻呼收发，提高寻呼效率，避免寻呼资源的浪费。
图4为本申请实施例提供的一种通信方法的流程示意图一，应用于网络设备，如图4所示，该方法包括：
S101、接收第一能力信息，第一能力信息用于指示第一终端设备支持的部分带宽。
示例性地，第一能力信息指示第一终端设备所支持的部分带宽，更具体地，第一能力信息指示第一终端设备所支持的部分带宽类型。例如指示第一终端支持在独立多播BWP上接收寻呼消息，还是在扩展initial BWP上接收寻呼消息，以实现多播寻呼业务。可选地，第一能力信息可以用1个比特(bit)或1个字段来指示终端设备支持的部分带宽，比如，当用1个bit来指示时，bit位的值为“1”表示支持在独立多播BWP上接收寻呼消息；反之，则表示不支持。
再例如，当用1个字段来指示是否支持信息时，当包括此字段时，表示支持该字段对应的多播能力，更具体地，例如，第一能力信息中包括A字段，代表第一终端设备支持在独立多播BWP上接收寻呼消息；第一能力信息中包括B字段，代表第一终端设备支持在扩展initial BWP上接收寻呼消息；反之，如果不包括此字段，表示不支持；需要说明的是，还可以通过多个bit或者至少一个字段来指示第一能力信息，本申请不限定指示第一能力信息的bit或字段的数量。
不同的终端设备，有各自对应的第一能力信息，第一能力信息用于指示第一终端设备支持的部分带宽。例如，图4A为终端设备与第一能力信息对应关系示意图，如图4A所示：终端设备A，对应的第一能力信息为支持第一部分带宽；终端设备B，对应的第一能力信息为支持第二部分带宽；终端设备C，对应的第一能力信息为支持第一部分带宽和第二部分带宽。其中，第一部分带宽、第二部分带宽为独立多播部分带宽或扩展初始部分带宽，扩展初始部分带宽即扩展initial BWP，通过在原有的initial BWP的基础上，对initial BWP在频域上进行扩展，形成扩展initial BWP，利用扩展出来的频带作为多播BWP，该多播BWP与扩展initial BWP相互重叠。独立多播部分带宽即独立多播BWP，通过独立多播BWP实现多播BWP的方式与通过扩展initial BWP实现多播BWP的方式不同，独立多播BWP在频域上与initial BWP没有重叠部分，是通过引入独立的BWP实现多播BWP。通过第一部分带宽和第二部分带宽对应不同的第一能力信息。例如，图4A中的第一部分带宽可为独立多播BWP，第二部分带宽可为扩展initial BWP。可以理解，对于终端设备A，支持在独立多播BWP上接收寻呼消息；对于终端设备B，支持在扩展initial BWP上接收寻呼消息。对于终端设备C，既支持在独立多播BWP上接收寻呼消息，又支持在扩展initial BWP上接收寻呼消息。
第一能力信息指示第一终端设备支持的部分带宽的实现方式有多种，例如，第一能力信息指示BWP标识，BWP标识对应终端设备支持的BWP；可选地，BWP标识可为一个 或多个。再例如，第一能力信息指示支持的BWP信息，BWP信息包括如下至少一种：BWP的起始位置、在频域的宽度、BWP对应的子载波间隔SCS。
第一能力信息为能够描述终端设备支持的BWP的标识，或者其他能够对BWP进行区分的字符串信息，该标识、字符串信息可以是预设的，此处不对第一能力信息的具体表现形式进行限定。
网络设备接收第一能力信息的方式有多种，例如，接收来自终端设备的第一能力信息，或者，接收来自核心网设备的能力信息。
在一种可能的实现中，终端设备向网络设备上报第一能力信息，用于指示支持接收寻呼消息的BWP。例如，终端设备向网络设备发送BWP标识，指示终端设备支持在BWP标识对应的BWP接收寻呼消息。具体地，例如，终端设备a向网络设备发送第一BWP标识，指示该终端设备a支持在独立多播BWP上接收寻呼消息，终端设备b向网络设备发送第二BWP标识，指示该终端设备b支持在扩展initial BWP上接收寻呼消息。
在另一种可能的实现中，核心网设备向网络设备发送第一能力信息，用于指示终端设备支持接收寻呼消息的BWP。例如，核心网设备向网络设备发送第一能力信息，第一能力信息中包括终端设备的标识信息，以及与该标识信息对应的BWP描述信息，可选地，BWP描述信息为BWP标识，终端设备支持在BWP标识对应的BWP接收寻呼消息。更加具体地，例如，核心网设备向网络设备发送第一能力信息，第一能力信息中包括终端设备的标识信息dev_1，以及与该终端设备的标识信息dev_1对应的第一BWP标识，该第一BWP标识用于指示标识信息为dev_1的终端设备支持在独立多播BWP上接收寻呼消息。再例如，核心网设备向网络设备发送第一能力信息，第一能力信息中包括终端设备的标识信息dev_2，以及与该终端设备的标识信息dev_2对应的第二BWP标识，该第二BWP标识用于指示标识信息为dev_2的终端设备支持在扩展initial BWP上接收寻呼消息。
进一步，网络设备可以根据第一能力信息确定第一终端设备支持接收寻呼消息的BWP。
S102、根据第一能力信息，在目标部分带宽上发送第一寻呼消息。
网络设备获得第一能力信息后，由于第一能力信息可以指示第一终端设备所支持的部分带宽，因此，网络设备根据该第一能力信息，可以确定一个目标部分带宽，以用于在该目标部分带宽上寻呼第一终端设备。其中，目标部分带宽是指用于向第一终端设备发送寻呼消息的BWP，例如第一终端设备支持的BWP为独立多播BWP，则目标部分带宽也为独立多播BWP；或者，第一终端设备支持的BWP为扩展initial BWP，则目标部分带宽也为扩展initial BWP，网络设备通过在目标部分带宽上，发送第一寻呼消息，可以实现对第一终端设备的寻呼，网络设备在目标部分带宽上发送第一寻呼消息的过程，此处不再赘述。
图5为本申请实施例提供的一种相关技术中网络设备对终端设备进行寻呼的示意图，如图5所示，由于不同的终端所支持的BWP不同，因此在独立多播BWP和扩展initial BWP上都可能有各自监听寻呼的位置，当网络设备想要寻呼终端设备时，网络设备无法确定终端设备接收寻呼的位置是在扩展initial BWP还是独立多播BWP，因此网络设备会在两个BWP的寻呼位置都进行寻呼，导致寻呼资源的浪费。
图6为本申请实施例提供的一种网络设备对终端设备进行寻呼的示意图，如图6所示，基站获得了第一能力信息，确定目标部分带宽(目标BWP)，进而可以在目标部分带宽上发送寻呼消息，对终端设备进行寻呼。
本申请中，网络设备通过接收第一能力信息，确定第一终端设备支持的目标部分带宽，向目标部分带宽上发送第一寻呼消息，其中，部分带宽用于承载寻呼或其他消息部分带宽用于承载寻呼或其他消息，由于目标部分带宽与该第一终端设备支持的部分带宽相匹配，在该目标部分带宽发送第一寻呼消息，可以减少网络设备在其他部分带宽上发送寻呼消息，相比于网络设备在多个部分带宽上尝试发送第一寻呼消息来说，能够有效减少网络设备的不必要的寻呼发送，缓解了寻呼资源浪费的问题，同时，能够有效减少第一终端设备的不必要的监听，降低终端设备的能耗，提高了寻呼效率。
图7为本申请实施例提供的一种通信方法的流程示意图二，如图7所示，本实施例提供的通信方法，在图4所示实施例提供的通信方法的基础上，按照第一能力信息的来源，对步骤S101进行了细化，则本实施例提供的通信方法包括：
S201、接收来自核心网设备的第二寻呼消息，第二寻呼消息中包括第一终端设备的标识信息。
核心网设备与网络设备之间通信连接，其中，网络设备例如为gNB。核心网设备例如为AMF，示例性地，AMF在需要进行多播寻呼时，向gNB发送第二寻呼消息，其中，第二寻呼消息中包括AMF需要进行寻呼的第一终端设备的标识信息以及具体的寻呼信息，gNB根据接收到的第二寻呼消息，能够将具体的寻呼信息发送至第一终端设备。
示例性地，第一终端设备的标识信息包括以下至少一种：终端标识、终端对应的组标识、终端对应的业务标识。
其中，终端标识用于唯一的指示一个终端设备。在一种可能的实现方式中，终端标识是核心网为终端设备配置的标识，具体地，终端标识例如是S-TMSI。在另一种可能的实现方式中，终端标识是存储在SIM卡中，例如IMSI；在又一种可能的实现方式中，终端标识是网络设备为终端设备配置的标识，具体地，终端标识例如为I-RNTI，这里，终端标识用于指示被寻呼的终端设备。
终端对应的组标识用于指示被寻呼的终端设备所对应的终端设备组，其中，终端设备组是指具有共同的组标识的多个终端设备，例如一个小区内的多个终端设备，终端设备组中的多个终端设备通过统一的组标识与其他外部网络设备进行通信连接。
终端对应的业务标识用于指示被寻呼的终端设备对应的业务标识，可选地，业务标识可以是多播业务标识；其中，多播业务的标识可以是TMGI或G-RNTI。
示例性地，第二寻呼消息中包括至少一个第一终端设备的标识信息，第一终端设备的标识信息与第一能力信息具有映射关系。在一种可能的实现方式中，网络设备内预设有至少一个第一能力信息，以及第一能力信息与终端设备的标识信息的映射表，该映射表中包括描述第一能力信息与终端设备的标识信息的映射关系的映射表项。网络设备根据第二寻呼消息中的第一终端设备的标识信息，以及该映射表中的映射表项，可以确定相应的第一能力信息。在另一种可能的实现方式中，第二寻呼消息中还包括有至少一个第一能力信息，各第一能力信息以一对一，或一对多的映射方式与第二寻呼消息中的第一终端设备的标识信息对应，即一个第一能力信息对应一个第一终端设备的标识信息，或者，一个第一能力信息对应多个第一终端设备的标识信息。网络设备通过第二寻呼消息，确定至少一个第一终端设备的标识信息，以及与该至少一个第一终端设备的标识信息对应的第一能力信息。
其中，第二寻呼消息包括以下至少一种：DRX配置、消息类型指示、寻呼优先级、TAI  list、寻呼尝试次数信息等。
本申请中，网络设备接收来自核心网设备的第二寻呼消息，从第二寻呼消息中获取第一终端设备的标识信息，根据预先获取的第一终端设备的标识信息与第一能力信息之间的映射关系，确定第一终端设备对应的第一能力信息。根据第一能力信息，在目标带宽上进行寻呼时，可以寻呼到该第一终端设备的目的。另外，终端标识可以指示一个终端设备，还可以指示一组终端设备，使网络设备可以通过一个终端标识对一组终端或者属于同一业务分组的多个终端设备进行寻呼，节省网络设备对第一终端设备寻呼的信令开销，同时提高网络设备对第一终端设备进行寻呼的效率。
在一种可能的实现方式中，第一终端设备的标识信息是第一终端设备上报给核心网设备的，或者，是核心网设备通过应用服务器获取的。第一终端设备的标识信息与第一终端设备的业务信息具有预设的映射关系，核心网设备可以通过第一终端设备的标识信息获知对应的业务信息，例如，核心网设备通过第一终端设备的标识信息，确定第一终端设备支持的多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)信息，和/或，第一终端设备感兴趣的多播业务信息，进而，确定具体地寻呼策略，实现与第一终端设备的业务信息相匹配的寻呼方式。
S202、根据第一能力信息，确定目标部分带宽。
图8为本申请实施例提供的一种确定目标部分带宽的流程示意图，如图8所示，在一种可能的实现方式中，网络设备确定目标部分带宽的方式包括：
当第一终端设备支持第一部分带宽时，确定目标部分带宽为第一部分带宽；当第一终端设备不支持第一部分带宽，且第一终端设备处于RRC空闲态或RRC非激活态，确定目标部分带宽为Initial BWP；当第一终端设备不支持第一部分带宽，且第一终端设备处于RRC连接态，确定目标部分带宽为Active BWP。其中，示例性地，第一部分带宽可以为多播BWP，或者扩展initial BWP。
具体地，由于第一部分带宽中承载了用于监听寻呼的位置，即search space和/或CORESET，因此，第一部分带宽的频域宽度大于初始部分带宽的频域宽度，和/或；第一部分带宽的频域位置不同于初始部分带宽的频域位置，和/或；第一部分带宽的子载波间隔不同于初始部分带宽的子载波间隔。第一部分带宽可以通过频域宽度、频域位置、子载波间隔中的至少一个与其他部分带宽进行区分。
在一种可能的实现方式中，在步骤S202之后，还包括：
S202a、向第一终端设备发送第一指示，第一指示用于指示目标部分带宽的信息。
示例性地，第一指示可以承载在网络设备发送给第一终端设备的配置信息中，用于指示第一终端设备接收寻呼的目标部分带宽信息。
其中，示例性地，目标部分带宽信息包括BWP标识，更具体地，BWP标识用于指示“扩展Initial BWP”，或者“独立多播BWP”。若目标部分带宽信息为BWP标识，终端设备根据BWP标识与BWP之间的映射关系确定BWP标识对应的目标部分带宽。在一种可能的实现中，终端设备确定BWP标识与BWP之间的映射关系，并发送给网络设备，例如终端设备在发送第一能力信息的同时可以发送BWP标识与BWP之间的映射关系；在另一种可能的实现中，网络设备确定BWP标识与BWP之间的映射关系，并发送给终端设备，相应的，终端设备接收来自网络设备的目标部分带宽信息和映射关系，目标部分带宽信息 为目标部分带宽的BWP标识，进一步，终端设备根据BWP标识和映射关系确定目标部分带宽，其中，网络设备确定的映射关系可以是根据来自核心网设备的指示信息确定的，例如，核心网设备确定BWP标识与BWP之间的映射关系并发送给接入网设备，接入网设备将映射关系发送给终端设备。
示例性地，目标部分带宽信息包括目标部分带宽在频域的位置信息指示，更具体地，例如，目标部分带宽信息包括描述“起始位置”和“频域带宽”的信息；再例如，目标部分带宽信息包括描述“结束位置”和“频域带宽”的信息；还例如，目标部分带宽信息包括描述“起始位置”和“结束位置”的信息。

示例性地，第一终端设备能够支持多种BWP，在接收网络设备发送的第一指示后，可以根据第一指示，在目标部分带宽对应的寻呼位置上接收寻呼消息，使得第一终端设备接收寻呼的目标部分带宽与网络设备发送寻呼的目标部分带宽相匹配。
本申请中，网络设备在确定目标部分带宽后，向第一终端设备发送用于指示该目标部分带宽的第一指示，使该第一终端设备能够获得目标部分带宽的信息，进而在该目标部分带宽上接收寻呼。其中，第一指示信息可以与第一寻呼消息同时发送，也可以在第一寻呼消息之前发送，通过向第一终端设备发送该第一指示，能够实现对第一终端设备的灵活配置，扩大本申请实施例的适用场景。
S203、在目标部分带宽上发送第一寻呼消息。
具体地，第一寻呼消息是网络设备根据第二寻呼消息生成的，第一寻呼消息包括第一终端设备的终端标识。示例性地，第一寻呼消息可以对应多播寻呼业务，也可以对应单播寻呼业务。

可选地，第一寻呼消息还可以包括接入类型，接入类型指示是否由于来自非3GPP访问的协议数据单元(Protocol Data Unit，PDU)会话而发出寻呼消息。
在一种可能的实现方式中，在目标部分带宽上发送第一寻呼消息，包括：在目标部分带宽对应的用于寻呼的时频资源位置上发送第一寻呼消息,其中，时频资源位置由目标部分带宽，以及目标部分带宽与search space、CORESET的对应关系确定的。不同的部分带宽与search space、CORESET的对应关系可以是网络设备预先配置的，例如，可以是网络设备通过RRC重配置消息发给终端设备的。
本申请实施例中，第一能力信息由核心网设备下发给网络设备，核心网设备通过不同的途径获得第一能力信息后，将终端设备的标识信息以及对应的能力信息下发给网络设备， 使网络设备能够获知第一终端设备所支持的BWP，从而使网络设备在向第一终端设备发送第一寻呼信息时，可以在第一终端设备所支持的目标部分带宽上进行寻呼，减少在多个BWP上进行寻呼所造成的寻呼资源浪费。
图9为本申请实施例提供的一种通信方法的流程示意图三，如图8所示，本实施例提供的通信方法，在图4所示实施例提供的通信方法的基础上，按照第一能力信息的来源，对步骤S101进行了细化，则本实施例提供的通信方法包括：

S501、确定第一能力信息，第一能力信息用于指示第一终端设备支持的部分带宽。
示例性地，第一终端设备确定第一能力信息，即确认自身所支持的部分带宽类型，例如为支持独立多播BWP，还是在Initial BWP上扩展用于多播寻呼的BWP，或者两种都支持等。其中，第一终端设备的第一能力信息可以是预先设置的，第一终端设备根据预设的信息，例如支持的协议、操作系统信息等，可以确定其所支持的部分带宽，即第一能力信息。

在一种可能的实现方式中，第一能力信息可以来自网络设备，网络设备在接收来自第一终端设备的第一能力信息后，向核心网设备转发，核心网设备接收网络设备转发的第一能力信息。例如，gNB将第一能力信息转发给AMF网元，其中，该转发消息可以为N2消息或NG2消息，N2为LTE中RAN设备和核心网设备之间的接口，NG2为NR中RAN设备和核心网设备之间的接口。
