具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1是本申请实施例提供的一种通信系统的架构100的示意图。如图1所示，该通信系统100包括核心网设备110、接入网设备120和至少一个终端设备(如图1中的终端设备130和终端设备140)。终端设备通过无线的方式与接入网设备相连，接入网设备通过无线或有线方式与核心网设备连接。核心网设备与接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的接入网设备的功能。终端设备可以是固定位置的，也可以是可移动的。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。
本申请的实施例对该通信系统中包括的核心网设备、接入网设备和终端设备的数量不做限定。例如图2是本申请实施例提供的一种通信系统的架构200的示意图。在图2所示的通信系统200中，包括核心网设备210、接入网设备220、接入网设备230以及终端设备240。
本申请实施例的技术方案可以应用于各种通信系统，例如：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、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、第五代(5th generation，5G)系统或新空口(new radio，NR)、以及未来的通信系统，例如6G通信系统等。

在一些部署中，gNB可以包括CU和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能；DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，以实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，以实现无线链路控制(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。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和AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，CU可以作为接入网中的网络设备，也可以作为核心网(core network，CN)中的网络设备，本申请对此不做限定。
此外，本申请实施例中的终端设备可以指用户设备(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、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、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)、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，5G网络中的终端设备或者下一代通信系统(例如，6G通信系统)的终端设备，或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
接入网设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请的实施例对接入网设备和终端设备的应用场景不做限定。

上述应用于本申请实施例的网络架构100或者网络架构200仅是举例说明，适用本申请实施例的网络架构并不局限于此，任何能够实现上述各个设备的功能的网络架构都适用于本申请实施例。
在本申请实施例中，如果没有特殊说明，网络设备均指接入网设备。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系统层，以及运行在操作系统层上的应用层。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。该操作系统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系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。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(例如处理器、芯片、或芯片系统等)。
为了便于理解本申请实施例，作出以下说明。
第一、在下文示出的本申请实施例中的文字说明或者附图中的术语，“第一”、“第二”等以及各种数字编号仅为描述方便进行的区分，而不必用于描述特定的顺序或者先后次序，并不用来限制本申请实施例的范围。例如，在本申请实施例中用于区分不同的信道带宽等。
第二、下文示出的本申请实施例中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可以包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其他步骤或者单元。
第三、在本申请实施例中，“示例性的”或者“例如”等词用于表示例子、例证或说明，被描述为“示例性的”或者“例如”的实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
第四、在本申请实施例中，小区可以称服务小区。是高层从资源管理或移动性管理或服务单元的角度来描述的。每个网络设备的覆盖范围可以被划分为一个或多个服务小区，且该服务小区可以看作由一定频域资源组成。在本申请实施例中，小区可以替换为服务小区或载波单元(component carrier，CC，或者称，成员载波、组成载波、载波等)。
第五、在本申请实施例中，信道带宽(channel bandwidth，CB)是指终端设备，例如UE，所支持的几种固定的带宽配置，如5MHz、10MHz等，是包含在终端设备对应的工作频带内的。传输带宽配置(transmission bandwidth configuration)是指在所配置的终端设备的信道带宽内实际用于发送内容的资源块(resource block，RB)的数量。传输带宽配置包含在信道带宽中，但不是全部占满，其余的部分为保护带(guard band)。信道带宽、传输带宽和保护带宽的示意图如图3所示所示。
第六、在本申请实施例中，point A是指0号公共资源块(common resource block，CRB)的0号子载波的中心位置。CRB是指整个系统带宽内对所有物理资源块(physical resource block，PRB)进行统一索引的所有带宽部分(bandwidth part，BWP)中PRB的参考点或者标尺。
第七、同步信号块(synchronization signal block，SSB)。SSB由主同步信号(Primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)和物理广播信道(physical broadcast channel block，PBCH)组成。其中，PSS即主同步序列，终端设备开机进入NR系统后，首先搜索PSS，一旦检测到了PSS，就会同步到PSS周期。同时，终端设备获知SSS的发送定时。通过检测SSS，确定该小区的物理层小区标识(physical-layer cell identity，PCI)。PBCH承载主信息块(master information block，MIB)，包含系统帧号，小区闭塞标识以及系统信息块(system information block，SIB)参数集等信息。终端设备要根据这些信息来获取网络设备广播的其余系统信息。
第八、在本申请实施例中，终端设备以某一信道带宽接入某一小区是指，终端设备采用某一信道带宽对应的业务带宽接入某一小区对应的系统带宽，例如，终端设备以第一信道带宽接入第一小区是指，终端设备采用第一信道带宽对应的业务带宽接入第一小区对应的系统带宽。
第九、带宽部分(BWP)：由于NR中同一小区中不同终端设备的发射或者接收能力 可能是不同的，系统可以为每个终端设备配置相应的带宽，这一部分配置给终端设备的带宽称为BWP，终端设备在自己的BWP上传输。BWP可以是载波上一组连续的频域资源，不同的BWP可以占用的频域资源可以部分重叠，也可以互不重叠。不同的BWP占用的频域资源的带宽可以相同，也可以不同，本申请对此不作限定。
第十，在本申请实施例中，“用于指示”可以包括用于直接指示和用于间接指示，也可以包括显式指示和隐式指示。将某一信息(如下文所述的第一信息)所指示的信息称为待指示信息，则具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如待指示信息本身或者该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的。例如，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
当前，通信系统中存在部分可以支持n28的45MHz全频段范围的终端设备，这部分终端设备还无法使用运营商可能获取的新频段，例如788MHz～798MHz。为了前向兼容，网络设备允许配置的系统带宽为40MHz。然而，对于仅能够使用30MHz信道带宽的终端设备来讲，由于终端设备的业务带宽(30MHz)与系统带宽(40MHz)不再相同，因此，该类型的终端设备将无法正常接入网络。具体地，30MHz信道带宽对应的保护带宽592.5kHz大于40MHz系统带宽对应的保护带宽552.5kHz。如图4所示，当终端设备以30MHz的业务带宽接入40MHz系统带宽时，若网络设备将初始下行BWP配置在频带下边缘，由于系统带宽的point A与终端设备业务带宽的point A的频域位置一致，导致30MHz业务带宽的下边缘低于758MHz，使得终端设备无法接入小区。即使初始下行BWP没有配置在频带下边缘，终端设备成功接入小区，网络设备在配置终端设备专用BWP时也会出现上述问题。
基于上述问题，本申请实施例提供的通信方法和装置，使得现网中的高能力终端设备能够充分利用网络设备下发的频谱资源的同时，其他终端依然可以正常接入，保证了系统性能的稳定性。
下面将结合附图，对本申请中的技术方案进行描述。
图5是本申请实施例提供的一种通信方法500的示意性流程图，如图5所示，该方法包括如下多个步骤。
S501，终端设备以第一信道带宽接入第一小区。
具体地，终端设备在未获取到先验信息的情况下，在同步栅格(synchronization raster)上盲检测或者监听网络设备发送的SSB，检测到SSB后，终端设备获取承载在MIB上的SIB1，通过SIB1获取网络设备下发的第一小区对应的载波带宽，并在初始下行BWP上以第一信道带宽接入该第一小区。
S502，终端设备向网络设备发送第一信息。
具体地，终端设备向网络设备发送的第一信息用于指示终端设备支持以第一信道带宽接入第二小区。或者，终端设备向网络设备发送的第一信息用于指示终端设备支持的第一信道带宽应用的保护带宽不大于第二信道带宽对应的最小保护带宽，其中，第二信道带宽大于第一信道带宽，第一信道带宽对应的最小保护带宽大于第二信道带宽对应的最小保护 带宽。
可选的，该第一信息还用于指示终端设备支持第二信道带宽。
在一种可实现的方式中，该第一信息可以承载在最大功率回退(maximum output power reduction，MPR)消息中。
示例性的，可以利用MPR未被定义的字段、比特、位图(bit map)、码位(code point)、或状态(state)来指示该第一信息。
S503，网络设备向终端设备发送第二信息。
具体地，网络设备接收到终端设备发送的第一信息后，网络设备根据终端设备支持以第一信道带宽接入第二小区，或者根据终端设备支持的第一信道带宽对应的保护带宽不大于第二信道带宽对应的最小保护带宽，获知该终端设备获知该终端设备能够以小带宽的业务带宽接入大带宽的载波小区。此时，网络设备向终端设备发送第二信息，该第二信息用于指示终端设备接入第二小区，同时，第二信息还用于指示第一信道带宽或第二信道带宽对应的载波带宽，该载波带宽为第二小区对应的载波带宽。其中，第一小区对应的频带与第二小区对应的频带属于同一个工作频带。
其中，该第二信息可以是网络设备以广播形式下发的SIB1携带的信息。
S504，终端设备以第一信道带宽接入第二小区。
具体地，终端设备接收到网络设备发送的第二信息后，以第一信道带宽接入第二小区。其中，终端设备接入第二小区时的第一信道带宽对应的频率范围，与终端设备接入第一小区时的第一信道带宽对应的频率范围不同。
在一种可实现的方式中，该第二小区可以是与第一小区共站的其他小区，或者该第二小区可以是第一小区的辅小区，本申请不做限定。
基于上述方案，本申请实施例提供的通信方法，网络设备可以根据终端设备上报的信息获取终端设备的能力，并基于终端设备的能力信息为终端设备配置大带宽的载波小区，使具有不同的终端设备可以依据自身能力灵活选择接入大带宽的小区。本申请的方法可以应用于扩展带宽的网络系统，能够兼顾网络系统中的各类终端设备，使支持更大带宽的终端设备充分利用频谱资源的同时，其他终端设备无需升级即可正常工作，保证网络系统的稳定性和通信的可靠性。
接下来，以第一信道带宽为30MHz，第二信道带宽为40MHz举例，对不同的终端设备的接入进行详细说明。
若终端设备为仅支持30MHz业务带宽的终端设备时，该方法如图6的通信方法600所示，具体地，可以包括如下多个步骤。
S601，终端设备以30MHz的信道带宽接入30MHz的小区。
可选地，在S601之前，网络设备向终端设备广播SSB，终端设备接收到SSB后，可获取承载在MIB上的SIB1的物理下行共享信道(physical downlink control channel，PDCCH)信息。并获取到30MHz的小区对应的载波带宽。通过获取的信息，终端设备在初始下行BWP上接入30MHz的小区。
S602，终端设备向网络设备上报支持以30MHz的信道带宽接入40MHz的小区。
具体地，终端设备接入30MHz的小区后，与网络设备建立无线资源控制(radio resource control，RRC)连接。
可选地，网络设备向终端设备发送RRC配置，终端设备通过RRC配置获取专用BWP，并在激活的BWP内向网络设备发送支持以30MHz的信道带宽接入40MHz的小区的指示信息。
可选地，该S602可以是该终端设备向网络设备发送其支持的30MHz的信道带宽的保护带宽小于或者等于40MHz的信道带宽的保护带宽。
应理解，根据图4可知，当该终端设备支持的30MHz的信道带宽的保护带宽不大于40MHz的信道带宽的保护带宽时，该终端设备能够以30MHz的信道带宽接入40MHz的小区。
S603，网络设备向终端设备发送指示终端设备以30MHz的信道带宽接入40MHz的小区的指示信息。
在一种可实现的方式中，网络设备接收到终端设备在S602中上报的指示信息后，可以通过配置辅小区配置40MHz的小区对应的载波带宽发送给终端设备。
示例性地，网络设备可以通过如下信令配置40MHz的辅小区对应的载波带宽，具体的，可以是通过secondaryCellGroup->reconfigurationWithSync->ServingCellConfigCommon->DownlinkConfigCommon->scs-SpecificCarrierList->carrierBandwidth来实现配置。
在另一种可实现的方式中，网络设备接收到终端设备在S602中上报的指示信息后，可以通过将终端设备切换至40MHz的小区，并将该40MHz的小区对应的载波带宽配置下发给终端设备。
示例性地，网络设备可以通过如下信令来配置40MHz的小区对应的载波带宽，具体的，可以是通过masterCellGroup->reconfigurationWithSync->ServingCellConfigCommon->DownlinkConfigCommon->scs-SpecificCarrierList->carrierBandwidth来实现配置。
可选的，该40MHz的小区可以与终端设备接入的30MHz的小区属于同站址小区。
S604，终端设备以30MHz的信道带宽接入40MHz的小区。
在一种可实现的方式中，若网络设备通过信令配置40MHz的辅小区对应的载波带宽，则终端设备以接收到的40MHz的载波带宽接入40MHz的辅小区。
在一种可实现的方式中，若网络设备通过信令配置40MHz的另一个小区对应的载波带宽，则终端设备以接收到的40MHz的载波带宽切换到40MHz的小区。
需要说明的是，在本申请实施例中，网络设备配置载波带宽仍为160RB，但是配置BWP只能从CRB#1开始，即跳过CRB#0。这样做的原因是：40MHz带宽的保护带宽为552.5kHz，假设保护带宽的下边界刚好为758MHz，30MHz业务带宽和40MHz系统带宽的pointA有相同的频域位置，则CRB#0的下边界为758.5525MHz。而30MHz业务带宽所需的保护带宽为592.5kHz，对应的频域位置为758.5925MHz，一个RB的频域宽度为180kHz。若从CRB#1开始配置BWP，则调度的起始频域位置为180kHz+758.5925MHz＝758.7725MHz>758.5925MHz。能够保证30MHz带宽对应的保护带宽不会落入CRB#0的范围。或者，配置的BWP不限制，可以从CRB#0开始配置，但是当调度传输的时候做一个限制只允许从CRB#1及更大index的CRB开始调度，不能调度CRB#0。这种做法能够获得和BWP配置限制相同的技术效果。
若终端设备为支持40MHz业务带宽的终端设备时，本申请实施例提供的通信方法如图7所示的方法700，具体地，可以包括如下多个步骤。
相较于上述图6所示的方法600来说，该方法700的区别在于S703。
具体地，当网络设备接收到终端设备在S702中上报的指示信息后，可通过上述S602中举例示出的信令，为终端设备配置30MHz的小区载波配置或者为终端设备配置40MHz的小区载波配置。
可选地，终端设备还可以通过S705向网络设备上报该终端设备能够以40MHz的信道带宽接入40MHz的小区。即，该终端设备为支持40MHz的信道带宽的高能力终端设备。
其中，该方法700的S701、S702以及S704可以相应的参考上述图6所示的方法600中的S601、S602以及S604，此处不再赘述。
此外，若终端设备为支持40MHz业务带宽的终端设备时，本申请实施例提供的通信方法还包括如图8所示的方法800，具体地，可以包括如下多个步骤。
相较于上述图7所示的方法700来说，该方法800的区别在于S804。
具体地，当终端设备接收到网络设备下发的指示信息后，终端设备选择以40MHz业务带宽接入40MHz系统带宽的小区。
当前，通信系统中还存在一种只支持第一信道带宽的终端设备，并且可以支持系统带宽内的所有频率范围，例如图9所示，若该终端设备支持30MHz的业务带宽，其可以使用758MHz-788MHz的信道带宽与网络设备进行通信，或者也可以使用773MHz-803MHz的信道带宽与网络设备进行通信。常见的此类终端设备，例如带宽滤波器。
图10是本申请实施例提供的一种通信方法1000的示意性流程图，如图10所示，该方法包括如下多个步骤。
S1001，终端设备以第一频率范围接入第一小区。
具体地，终端设备在未获取到先验信息的情况下，在同步栅格(synchronization raster)上盲检测或者监听网络设备发送的SSB，通过SIB1获取网络设备下发的第一小区对应的载波带宽，以第一频率范围接入该第一小区。
应理解，网络设备广播的SIB1还包括子载波间隔以及载波所在的频段号，以及SSB与point A的偏移位置等信息。
S1002，终端设备向网络设备发送第一信息。
可选的，该第一信息用于指示终端设备支持的频率范围超过第一频率范围。
可选的，该第一信息用于指示终端设备能够支持第二频率范围。
可选的，该第一信息用于指示所述终端设备支持当第一信道带宽应用/对应的保护带宽不大于第二信道带宽对应的最小保护带宽时，能够满足射频指标。其中，第一信道带宽为第一频率范围对应的信道带宽，第二信道带宽大于第一信道带宽，且第二信道带宽对应的最小保护带宽小于第一信道带宽对应的最小保护带宽。
在一种可实现的方式中，该第一信息可以承载在最大功率回退(maximum output power reduction，MPR)消息中。
示例性的，可以利用MPR未被定义的字段、比特、位图(bit map)、码位(code point)、或状态(state)来指示该第一信息。
S1003，网络设备向终端设备发送第二信息。
具体地，网络设备接收到终端设备发送的第一信息后，网络设备向终端设备发送第二信息，该第二信息用于指示终端设备接入第二小区。
其中，该第二信息可以是网络设备以广播形式下发的SIB1携带的信息。
S1004，终端设备接入第二小区。
具体地，终端设备接收到网络设备发送的第二信息后，可以以第一信道带宽接入第二小区或者以第一信道带宽接入第二小区或者以第三信道带宽接入第二小区。其中，终端设备接入第二小区时的第一信道带宽对应的频率范围，与终端设备接入第一小区时的第一信道带宽对应的频率范围不同。
可选的，第一频率范围为终端设备接入第一小区时的第一信道带宽对应的频率范围，第二频率范围为终端设备接入第二小区时的第一信道带宽对应的频率范围。示例性的，若第一信道带宽为30MHz，当第一频率范围为758MHz-788MHz时，第二频率范围为773MHz-803MHz。
可选的，第一频率范围为终端设备接入第一小区时的第一信道带宽对应的频率范围，第二频率范围为终端设备接入第二小区时的第二信道带宽对应的频率范围。示例性的，若第一信道带宽为30MHz，第二信道带宽为40MHz时，当第一频率范围为758MHz-788MHz时，第二频率范围可以是788MHz-798MHz、773MHz-798MHz、或者778MHz-798MHz等。
可选的，第一频率范围为终端设备接入第一小区时的第一信道带宽对应的频率范围，第二频率范围大于终端设备接入第二小区时的第三信道带宽对应的频率范围。其中，当第一信息用于指示终端设备支持当第一信道带宽应用/对应的保护带宽不大于第二信道带宽对应的最小保护带宽，且能够满足射频指标时，第三信道带宽对应的最小保护带宽不大于第一信道带宽应用/对应的所述保护带宽。示例性的，若第一信道带宽为30MHz，第二信道带宽为40MHz时，第三信道带宽可以为25MHz，20MHz等比30MHz小的标准带宽。当第一频率范围为758MHz-788MHz时，第二频率范围可以是788MHz-798MHz、773MHz-798MHz、或者778MHz-798MHz等。但需要说明的是，为了满足单调性，同时能够保证射频指标，该终端设备的30MHz应用的保护带宽不大于40MHz对应的保护带宽552.5kHz，同时30MHz应用的这个保护带宽需要大于等于25MHz/20MHz等更小的标准带宽对应的保护带宽。
在一种可实现的方式中，该第二小区可以是与第一小区共站的小区，或者该第二小区可以是第一小区的辅小区，本申请不做限定。
基于上述方案，本申请实施例提供的通信方法，可以应用于扩展带宽的网络系统，能够兼顾网络系统中的各类终端设备，保证网络系统的稳定性和通信的可靠性。
需要说明的是，在本申请提供的上述实施例中，其应用的通信系统或者应用的场景中的终端设备或者用户设备，应至少包括legacy UE，即本申请的实施例中所说明的终端设备应用于legacy UE共存的场景中。
此外，还需要说明的是，本申请的实施例仅针对下行信道进行了说明，对于上行信道传输来说，本申请依然适用。
