核心网设备可以与多个接入网设备连接，用于控制接入网设备，并且，可以将从网络侧(例如，互联网)接收到的数据分发至接入网设备。

此外，本申请实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于：磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(Compact Disc，CD)、数字通用盘(Digital Versatile Disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(Erasable Programmable Read-Only Memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的 各种其它介质。
需要说明的是，在本申请实施例中，在应用层可以运行多个应用程序，此情况下，执行本申请实施例的通信方法的应用程序与用于控制接收端设备完成所接收到的数据所对应的动作的应用程序可以是不同的应用程序。
图1是能够适用本申请实施例通信方法的系统100的示意图。如图1所示，该系统100包括接入网设备102，接入网设备102可包括1个天线或多个天线例如，天线104、106、108、110、112和114。另外，接入网设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
接入网设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，接入网设备102可以与类似于终端设备116或终端设备122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路(也称为下行链路)118向终端设备116发送信息，并通过反向链路(也称为上行链路)120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(Frequency Division Duplex，FDD)系统中，例如，前向链路118可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(Time Division Duplex，TDD)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为接入网设备102的扇区。例如，可将天线组设计为与接入网设备102覆盖区域的扇区中的终端设备通信。接入网设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端设备发送信号。在接入网设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，接入网设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外，与接入网设备通过单个天线或多天线发射分集向它所有的终端设备发送信号的方式相比，在接入网设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，接入网设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是PLMN网络、D2D网络、M2M网络、IoT网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他接入网设备，图1中未予以 画出。
作为示例而非限定，本申请实施例的通信方法可以应用于例如大带宽的通信系统中。
具体地说，随着移动用户的增加，以及大容量业务的出现(比如高清视频业务等)，移动通信向未来的5G系统或NR系统等的演进需要的一个重要的方面就是支持大带宽，带宽越大，用于进行数据传输的带宽资源就越多，能够支持的业务量就越大。在载波带宽为大带宽的通信系统中，考虑到UE的成本以及UE的业务量，UE支持的带宽可能小于载波带宽。其中，UE支持的带宽越大，UE的处理能力越强，UE的数据传输速率可能越高，UE的设计成本可能越高。例如，在5G系统中，载波带宽最大可能为400兆赫兹(MHz)，UE的射频带宽能力可能为20MHz、50MHz或100MHz等。在无线通信系统中，不同UE的射频带宽能力可以相同也可以不同。
在载波带宽为大带宽的通信系统中，由于UE的射频带宽能力小于载波带宽，提出了带宽部分(Bandwidth Part或carrier Bandwidth Part，BWP)的概念，即，一个BWP包括频域上的连续若干个PRB。
在网络设备为终端设备分配BWP时，网络设备和终端设备需要首先对资源的粒度和位置有一个一致的理解，然后，网络设备向终端设备指示为其分配的BWP所包括的PRB，进而确定该BWP。
因此，通信方法可以应用于UE确定BWP所处的位置和包含的PRB的数量的过程。
下面，结合图2对一个网络设备(例如，接入网设备，以下，为了便于理解和说明，记做网络设备#A)与一个终端设备(以下，为了便于理解和说明，记做终端设备#B)确定公共带宽中的PRB编号的基准PRB(记做PRB#0)的位置的方法200进行详细说明。公共带宽是指的系统最大可能支持的载波带宽，例如可能是275PRB。或者是绝对的PRB网格。其中，该PRB#0可以位于系统带宽中，或者，该PRB#0也可以是系统带宽外的PRB，本申请并未特别限定。系统带宽也称为小区带宽，载波带宽，是指基站实际采用的带宽。公共带宽的一个作用是BWP的配置。基站和UE对公共带宽的粒度和位置有一致的理解，基站通过指示BWP在公共带宽中的位置和大小，UE就可以确定对应的BWP的位置和大小。通过公共带宽，UE不需要知道基站实际采用的系统带宽的大小，UE确定BWP之后，后续的资源分配就在该BWP内进行。
在S210，网络设备#A可以确定该PRB#0的位置(具体地说，是频域位置)。
其中，PRB#0是公共带宽种PRB进行编号的参照点，即，自该PRB#0向高频方向PRB的编号依次递增。
作为示例而非限定，在本申请实施例中，网络设备#A可以根据分配给小区中多个终端设备#B的用于通信的资源(具体地说，是频域资源，例如，BWP，以下，为了便于理解和区分，记作BWP#A)，确定PRB#0的位置，以使该PRB#0对应的频率低于小区内所有UE的BWP#A对应的最低频率，即，基于该PRB#0的位置编号后的各PRB包括该小区内对应的全部UE的所有BWP#A对应的PRB。
作为示例而非限定，设网络设备#A所使用的系统带宽为系统带宽#A，则该PRB#0对应的频率可以低于该系统带宽#A的最低频率。
或者，PRB#0对应的频率也可以该高于该系统带宽#A的最低频率，本申请并未特别限定。
作为示例而非限定，该PRB#0可以作为网络设备#A提供的小区中的公共物理资源块(Common PRB)。
另外，网络设备#A可以确定用于确定该PRB#0的位置的参考点(以下，为了便于理解和区分，记作参考点#1)。
其中，参考点可以是绝对无线频率信道号指示的位置，本申请实施例中的绝对无线频率信道号是针对预配置的频率范围以设置粒度来划分后，进行编号得到的。设置粒度可以是信道栅格(channel raster)。一个信道栅格的大小可以为预定义的。比如一个信道栅格的大小为100kHz，也可以为一个PRB的大小，也可以为一个子载波的大小等等。本实施例中该信道栅格的大小是子载波级的，可选地，在sub6GHz的时候可以是15kHz，在毫米波(mmWave)的范围内可以是60kHz。

例如，网络设备#A还可以确定该参考点#1对应的是0号子载波(记作子载波#0)还是6号子载波(记作子载波#6)。或者说，网络设备#A还可以确定无线绝对频率信道号对应的是子载波#0还是子载波#6。
作为示例而非限定，网络设备#A可以根据该系统带宽#A所包含的RB个数确定信道栅格对应的是子载波#0还是子载波#6。
例如，当RB个数为偶数的时候，网络设备#A可以确定信道栅格对应的是子载波#0，或者说，网络设备#A可以确定参考点#1对应的是子载波#0，即，网络设备#A可以确定参考点#1为子载波#0的中心。
当RB个数为奇数的时候，网络设备#A可以确定信道栅格对应的是子载波#6，或者说，网络设备#A可以确定参考点#1对应的是子载波#6，即，网络设备#A可以确定参考点#1为子载波#6的中心。
应理解，以上列举的网络设备#A确定PRB#0、参考点#1以及参考点#1对应的子载波的标识的方法仅为示例性说明，本申请并未限定于此，其他能够使网络设备确定PRB编号起点以及用于确定该PRB编号起点的绝对频率位置的方法均落入本申请的保护范围内。
此外，网络设备#A还可以确定偏移量，具体地说，该偏移量指示该参考点#1与参考点#2之间的偏移单位的数量，其中，该参考点#2可以是该PRB#0的频域端点，例如，PRB#0的最低频点或者，PRB#0的子载波0所在的位置。
即，在本申请实施例中，该参考点#1与该参考点#2之间可以包括多个偏移单位，其中，每个偏移单位的大小相同。
并且，在本申请实施例中，偏移单位的大小可以以资源单位来衡量，或者说，偏移单 位与资源单位之间存在比例关系，随后，对该资源单位进行详细说明。
即，在本申请实施例中，一个偏移单位的大小可以是1个资源单位。
或者，在本申请实施例中，一个偏移单位的大小可以是1/2个资源单位。
作为示例而非限定，在本申请实施例中，偏移单位与资源单位的比例关系(即，一个偏移单位的大小是一个资源单位还是半个资源单位)可以是预定义的。例如，偏移单位与资源单位的比例关系可以是通信协议规定的。再例如，偏移单位与资源单位的比例关系可以是运营商或制造商预设在网络设备和终端设备中的。再例如，偏移单位与资源单位的比例关系可以是使用者或管理员输入至网络设备和终端设备中的。
或者，在本申请实施例中，偏移单位与资源单位的比例关系可以是网络设备#A通知给终端设备#B的。
应理解，以上列举的偏移单位与资源单位的比例关系的确定方式仅为示例性说明，本申请并未限定于此，只要能够使网络设备#A与终端设备#B所确定的偏移单位与资源单位的比例关系一致即可。
下面，对资源单位进行详细说明。
在本申请实施例中，资源单位的大小可以是预定义的。例如，资源单位的大小可以是通信协议规定的。再例如，资源单位的大小可以是运营商或制造商预设在网络设备和终端设备中的。再例如，资源单位的大小可以是使用者或管理员输入至网络设备和终端设备中的。
或者，在本申请实施例中，资源单位的大小系可以是网络设备#A通知给终端设备#B的。
在本申请实施例中，资源单位的大小可以以PRB来衡量，或者说，资源单位与PRB之间存在比例关系。
即，在本申请实施例中，一个资源单位的大小可以是1个PRB。
或者，在本申请实施例中，一个资源单位的大小可以是1/2个PRB。
再或者，在本申请实施例中，一个资源单位的大小可以是1/4个PRB。
再或者，在本申请实施例中，一个资源单位的大小可以是1/8个PRB。

再或者，在本申请实施例中，一个资源单位的大小可以是3个子载波。
再或者，在本申请实施例中，一个资源单位的大小可以是1.5个子载波。
作为示例而非限定，在本申请实施例中，资源单位与PRB的比例关系的比例关系可以是预定义的。例如，资源单位与PRB的比例关系可以是通信协议规定的。再例如，资源单位与PRB的比例关系可以是运营商或制造商预设在网络设备和终端设备中的。再例如，资源单位与PRB的比例关系可以是使用者或管理员输入至网络设备和终端设备中的。
或者，在本申请实施例中，资源单位与PRB的比例关系可以是网络设备#A通知给终端设备#B的。
再或者，在本申请实施例中，资源单位与PRB的比例关系可以是根据系统信息确定 的。
例如，系统信息可以包括系统带宽使用的子载波间隔。
再例如，系统信息还可以包括系统带宽使用的循环前缀(Cyclic Prefix，CP)。
再例如，系统信息还可以包括系统带宽使用的系统参数numerology。
作为示例而非限定，以下表1示出了不同的系统信息所对应的资源单位与PRB的比例关系的一例。
表1
子载波间隔 一个资源单位的大小
15kHz 1/2个PRB(或者说，6个子载波)
30kHz 1/4个PRB(或者说，3个子载波)
60kHz 1/8个PRB(或者说，1.5个子载波)
在一种可能的情况下，偏移量的取值范围的一种可能为276*4*2。其中，276表示最大275个PRB，考虑同步信号和数据的PRB Grid之间可能存在最大1个PRB的偏移，4表示60kHz的子载波间隔是15kHz子载波间隔的4倍，如果采用15kHz的1/2个PRB的粒度作为偏移单位，则需要定义偏移量的取值范围为276*4*2。
应理解，以上列举的资源单位与PRB的比例关系仅为示例性说明，本申请并未限定于此，只要能够使网络设备#A与终端设备#B所确定的资源单位与PRB之间的比例关系一致即可。
在S220，网络设备#A可以向终端设备#B发送信息#1(即，第一指示信息的一例)，该信息#A用于指示上述参考点#1，具体地说，该信息#A用于指示是参考点#1的频域位置。
并且，网络设备#A可以向终端设备#B发送信息#2(即，第二指示信息的一例)。该信息#2用于指示上述偏移量，即，参考点#1与参考点#2之间的偏移单位的数量。
从而，在S230，终端设备#B能够基于该信息#1确定参考点#1的频域位置。
并且，终端设备#B可以基于该信息#2确定参考点#1与参考点#2之间的偏移单位的数量。
如图3所示，参考点对应子载波的标识不同时，最终确定的PRB编号起点的位置可能相异。
因此，在S230，终端设备#B还可以确定该参考点#1对应的子载波的标识。
作为示例而非限定，在本申请实施例中，终端设备#B还可以基于以下方式确定的该参考点#1对应的子载波的标识。
方式1

作为示例而非限定，该信息#3可以占用1个比特位。
作为示例而非限定，在发送信息#3的情况下，信息#2的偏移粒度为PRB，偏移量的最大范围为276*4。
并且，作为示例而非限定，该信息#3可以携带在辅小区(Scell)的配置信息中，用于在Scell进行BWP的配置。Scell的配置信息可以承载在网络设备#A向终端设备#B发送的无线资源控制(Radio Resource Control，RRC)信令中，并且，可选地，该RRC信令可以是终端设备#B专有的RRC信令。
并且，作为示例而非限定，该信息#3可以携带在辅小区(Scell)的FDD的上行载波的配置信息中，用于在Scell在FDD情况下进行上行BWP的配置。Scell的配置信息可以承载在网络设备#A向终端设备#B发送的无线资源控制(Radio Resource Control，RRC)信令中，并且，可选地，该RRC信令可以是终端设备#B专有的RRC信令。
作为示例而非限定，在本申请实施例中，上述方法还可以用在增补上行链路(Supplementary Uplink，SUL)的BWP的配置中，此时，该信息#3可以携带在SUL的配置信息中，用于在SUL进行BWP的配置。SUL的配置信息可以承载在网络设备#A向终端设备#B发送的无线资源控制(Radio Resource Control，RRC)信令中，并且，可选地，该RRC信令可以是终端设备#B专有的RRC信令。
作为示例而非限定，在本申请实施例中，上述方法还可以用在主小区Pcell的FDD情况下上行载波的BWP的配置中，此时，该信息#3可以携带在剩余最小系统信息(Remaining Minimum System Information，RMSI)中，用于在Pcell的FDD情况下的上行载波进行BWP的配置。
方式2
可选地，网络设备#A和终端设备#B可以基于偏移量的奇偶情况，确定该参考点#1对应的子载波的标识。
例如，如果偏移量为奇数，或者说，该信息#2确定参考点#1与参考点#2之间的偏移单位的数量为奇数，则网络设备#A和终端设备#B可以确定该参考点#1对应子载波#0。
如果偏移量为偶数，或者说，该信息#2确定参考点#1与参考点#2之间的偏移单位的数量为偶数，则网络设备#A和终端设备#B可以确定该参考点#1对应子载波#6。
应理解，以上列举的网络设备#A和终端设备#B可以基于偏移量的奇偶情况，确定该参考点#1对应的子载波的标识的具体规则仅为示例性说明，本申请并未限定于此，例如，如果偏移量为奇数，则网络设备#A和终端设备#B可以确定该参考点#1对应子载波#6。如果偏移量为偶数，则网络设备#A和终端设备#B可以确定该参考点#1对应子载波#0。
可选地，在本申请实施例中，网络设备#A和终端设备#B可以在确定偏移单位与资源单位的比例满足规定要求时，基于偏移量的奇偶情况，确定该参考点#1对应的子载波的标识。
例如，在本申请实施例中，网络设备#A和终端设备#B可以在确定一个偏移单位的大小为1/2个资源单位时，基于偏移量的奇偶情况，确定该参考点#1对应的子载波的标识。
即，此情况下，终端设备#B还需要获知偏移单位与资源单位的比例。
作为示例而非限定，例如，偏移单位与资源单位的比例(即，一个偏移单位的大小为1个资源单位还是1/2个资源单位)可以是预定义的。例如，偏移单位与资源单位的比例关系可以是通信协议规定的。再例如，偏移单位与资源单位的比例关系可以是运营商或制造商预设在网络设备和终端设备中的。再例如，偏移单位与资源单位的比例关系可以是使用者或管理员输入至网络设备和终端设备中的。
或者，在本申请实施例中，网络设备#A还可以向终端设备#B发送信息#4，该信息#4可以用于指示偏移单位与资源单位的比例。
从而，终端设备#B可以基于该信息#4确定偏移单位与资源单位的比例，进而可以在一个偏移单位的大小为1/2个资源单位时，基于偏移量的奇偶情况，确定该参考点#1对应的子载波的标识。
由此，通过上述方式1或方式2，终端设备#B可以基于该信息#3确定该参考点#1对应的子载波的标识，进而，终端设备#B可以确定系统带宽中PRB的网格(Gird)。
在本申请实施例中，确定PRB#0的位置，除了需要使用上述参考点#1的位置、参考点#1对应的子载波标识和偏移量以外，还需要使用偏移单位的大小。
在本申请实施例中，终端设备#B也可以基于默认的偏移单位的大小确定PRB#0’的位置，进而基于预设的位置关系，确定PRB#0的位置(即，方式a)，或者，终端设备#B可以确定偏移单位的大小，进而基于上述参数确定PRB#0的位置(即，方式b)。下面，对上述两种方式分别进行详细说明。
方式a
在本申请实施例中，终端设备#B可以基于上述参考点#1的位置、参考点#1对应的子载波标识、偏移量和默认的偏移单位的大小，确定默认的PRB编号起点所对应的PRB(记作，PRB#0’)的位置。
例如，网络设备#A可以向终端设备#B发送信息#6，该信息#6用于指示默认的偏移单位的大小(或者说，默认的资源单位的大小)。
再例如，该默认的偏移单位的大小可以是基于默认的系统信息确定的，该默认的系统信息可以是默认的numerology、默认的子载波间隔或默认的CP中的任意一种参数的信息。
例如，设默认的子载波间隔为15kHz，则终端设备#B可以基于上述表1确定默认的子载波间隔为15kHz时，默认的资源单位的大小(1/2个PRB，或者说，6个子载波)，进而，终端设备#B可以基于默认资源单位的大小以及偏移单位与资源单位的比例，确定默认偏移单位的大小。
其中，该默认的系统信息可以是预定义的，例如，默认的系统信息可以是通信协议规定的。再例如，默认的系统信息可以是运营商或制造商预设在网络设备和终端设备中的。再例如，默认的系统信息可以是使用者或管理员输入至网络设备和终端设备中的。
或者，网络设备#A可以向终端设备#B发送该默认的系统信息。
由此，终端设备#B能够基于上述参考点#1的位置、参考点#1对应的子载波标识、偏移量和默认的偏移单位的大小，确定默认的子载波间隔下，PRB#0’的位置。
在本申请实施例中，网络设备#A和终端设备#B可以获取位置关系信息，其中，该位置关系信息可以用于指示多种系统信息下的PRB编号起点对应的PRB的位置关系。例如，如图4示出了该位置关系的一例。
从而，终端设备#B可以基于上述位置关系和如上所述确定PRB#0’的位置，确定该系统带宽#A实际使用的系统参数下的PRB#0的位置。
图5示出了默认的系统参数为15kHz时，基于方式a确定的实际的系统参数为30kHz时系统带宽中的各PRB的编号的情况的一例。
方式b
在本申请实施例中，终端设备#B还可以确定该偏移单位的大小(或者说，资源单位的大小)。
例如，网络设备#A可以向终端设备#B发送信息#5(即，第五指示信息的一例)，该信息#5用于指示偏移单位的大小(或者说，资源单位的大小)。
再例如，该偏移单位的大小可以是根据系统信息确定的，例如，该系统信息可以包括系统带宽#A所使用的numerology、子载波间隔或CP中的任意一种参数的信息。
例如，设系统带宽#A使用的子载波间隔为30kHz，则终端设备#B可以基于上述表1确定子载波间隔为30kHz时，资源单位的大小(1/4个PRB，或者说，3个子载波)，进而，终端设备#B可以基于资源单位的大小以及偏移单位与资源单位的比例，确定偏移单位的大小。
其中，该系统信息可以是预定义的，例如，系统信息可以是通信协议规定的。再例如，系统信息可以是运营商或制造商预设在网络设备和终端设备中的。再例如，系统信息可以是使用者或管理员输入至网络设备和终端设备中的。
或者，网络设备#A可以向终端设备#B发送该系统信息。
由此，终端设备#B能够基于上述参考点#1的位置、参考点#1对应的子载波标识、偏移量和偏移单位的大小，确定规定子载波间隔下，网络设备#A所确定的PRB#0的位置。
作为示例而非限定，例如，在本申请实施例中，可以使用3bit来指示系统信息，即，指示信息为15kHz，30kHz，60kHz，120kHz，240kHz和480kHz中的哪一种。
再例如，可以结合系统带宽所在的频带来指示系统信息。
例如，当系统带宽所在的频带(Band)为6GHz以下时，系统信息可能的numerology为15kHz或30kHz或60kHz，从而，可以用2bit的指示信息来区分。
再例如，当系统带宽所在的频带为6GHz以上时，系统信息可能的numerology为60kHz和120kHz，从而，可以用2bit的指示信息来区分。
如图5，以系统带宽为5MHz为例，假设网络设备和终端设备预定义默认的numerology(即，系统信息的一例)为15kHz，而实际在该载波上，网络设备为终端设备调度30kHz的数据。则该默认的系统信息下，系统带宽可以包括有25PRB，最小保护带对称分布在载波的两边。为了保证不同numerology的PRB边界对齐，30kHz的PRB Grid可能的位置如图5所示。对30kHz而言，需要的最小保护带宽为图7所示。因此，为了保证30kHz的业务的正常使用，图5中的PRB#0或者PRB#10将不能使用。实际使用的时候会浪费1个PRB。
因此，基于方式b，由于网络设备可以向终端设备指示了numerology，终端设备可以基于方式b直接确定参考点对应的子载波的标识为6号，则基于该方式b确定的11个PRB都可以正常使用，此时不会有浪费。
另外，在本申请实施例中，该系统带宽可以是基于FDD方式使用的载波的带宽。
此情况下，本申请实施例提供的技术可以应用于针对FDD情况下的上行的BWP配置。
具体地说，对于主小区(Primary Cell，Pcell)，本申请实施例提供的方案可以应用于针对上行传输的资源调度。
此情况下，参考点#1对应子载波#0还是子载波#6的指示信息可以包含在RMSI中。
或者，参考点#1对应子载波#0还是子载波#6可以通过调整偏移单位的数量(或者说， 资源单位的大小)来实现,例如，资源单位的大小可以是下行检测到的同步信号块(Synchronization Signal Block，SSB)对应的numerology下的PRB大小的一半。
对辅小区(Secondary Cell，Scell)，可以参考点#1对应子载波#0还是子载波#6的指示信息协议携带在下行的Scell的配置信息中，或者上行的Scell的配置信息中。
其中，参考点#1对应子载波#0还是子载波#6的指示信息可以与下行的偏移量指示信息一并发送，或者，参考点#1对应子载波#0还是子载波#6的指示信息可以与上行的偏移量指示信息一并发送。
另外，对于Scell，可以进一步指示上行的numerology和偏移量的对应关系，或者，上行的numerology和资源单位的大小之间关系可以预定义。
作为示例而非限定，在本申请实施例中，上述方法还可以用在增补上行链路(Supplementary Uplink，SUL)的BWP的配置中。此情况下，参考点#1对应子载波#0还是子载波#6的指示信息可以包含在SUL的配置信息中。并且，SUL的配置信息可以承载在网络设备#A向终端设备#B发送的无线资源控制(Radio Resource Control，RRC)信令中，并且，可选地，该RRC信令可以是终端设备#B专有的RRC信令。
其中，参考点#1对应子载波#0还是子载波#6的指示信息可以与上行的偏移量指示信息一并发送。
另外，对于SUL小区，可以进一步指示上行的numerology和偏移量的对应关系，或者，上行的numerology和资源单位的大小之间关系可以预定义。
在本申请实施例中，上述信息#1～信息#6中的部分或全部可以承载于同一消息或信令中一并发送，或者，上述信息#1～信息#6中的部分或全部信息可以承载于不同消息或信令中单独发送，本申请并未特别限定。
由此，基于上述过程，能够在终端设备无需获知系统带宽的大小的情况下，完成PRB#0的确定过程。由于网络设备无需告知终端设备系统带宽的大小，能够支持载波带宽的灵活变化，可以调整频谱的使用方法，比如部分带宽可以用于预留做其他用处；可以实现小区间的干扰协调，通过调整载波的中心和带宽避免强干扰；可以对不同的应用采用不同的载波，比如eMBB业务和URLLC业务可以采用不同的载波；可以适应业务量的灵活变化。并且，在LTE中，系统带宽是由PBCH通知的。在NR中，为了满足系统带宽的灵活变化，如果仍然采用PBCH通知，则系统带宽变化后，UE可能无法工作，此时需要小区重启，所有UE需要断开连接重新接入，过程会变得复杂。根据本申请提供的通信方法，能够避免该问题的发生。
