为了避免上述可能的问题发生，可以在大带宽中只发送一个信号。例如可以在160MHz的大带宽中只发送一个SSB，以及可以将终端设备2通过终端设备2专用的信令配置一个新的所述终端设备2专用的载波在100M右侧，从而通过一个SSB即可扩大所述终端设备可以使用的频率范围，并且终端设备也不必须具有载波聚合的能力。但是现有的BWP基于RIV配置，计算RIV时采用的RB的个数最大为275，且BWP的起始位置为160MHz的左侧第一个RB，导致终端设备的BWP不能配置在100M的右侧以外，不能实现两个载波共享一个SSB的目的，因此无法很好解决上述问题。

在一种可能的设计中，所述BWP的带宽范围大于275个资源块RB。
在该方法中，终端设备可以在大于275个RB的带宽范围内确定BWP，终端可使用的频率范围提高，充分利用网络设备的大带宽特性，在大带宽范围内网络设备可以只发送一个广播信息，节省系统广播信息的开销，提升了频谱利用率，提高通信系统容量。
在一种可能的设计中，第一带宽参数为所述终端设备当前接入小区的载波带宽。
在一种可能的设计中，所述当前小区的载波带宽为小区的公共带宽或为公共广播消息中广播的公共带宽。
在一种可能的设计中，所述BWP的起始位置与所述终端设备专用的载波带宽的起始位置相关。

本申请实施例的技术方案可以应用于各种通信系统(也称无线通信系统)。通信系统通常包括但不限于第四代移动通信(4th-generation，4G)网络、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、5G通信系统或NR以及未来的其他通信系统如6G等。只要该通信系统中存在实体需要发送下行数据以及导频信息，另一个实体需要接收对应的下行数据以及导频信息均可，实体可以理解为通信系统中的通信设备，包括网络设备和/或终端设备。可以理解的是，本申请实施例也可以用于其他通信系统，只要该通信系统存在下行通信链路和上行通信链路。
例如可以为如图1所示的通信系统，该通信系统由基站(Base station)和UE1～UE3组成，在该通信系统中，基站可以发送下行数据给终端设备UE1～UE4，同时终端设备UE1～UE4也可以发送上行数据给基站。
为了便于理解本申请实施例，先对本申请实施例的应用场景进行说明。
在无线通信系统中，按照发送节点和接收节点种类的不同，可以将通信分为不同的类型。通常，将网络设备向终端设备发送信息称为下行(downlink，DL)通信，将终端设备向网络设备发送信息称为上行(uplink，UL)通信，即在下行通信中发送节点为网络设备，接收节点为终端设备，在上行通信中发送节点为终端设备，接收节点为网络设备。
网络设备(如基站)在下行信号中周期性的发送广播信号供终端设备接入使用，例如所述广播信号可以为单边带(single side band，SSB)信号。以网络设备为基站进行说明，基站在发送广播信号时，无论小区中是否有用户都会周期性的发送，而不传输数据业务信息，因此基站发送的广播信号会占用固定的系统开销。所述广播信号中包括小区的消息，例如包括小区的载波带宽和频率位置，小区的载波带宽最大值为275个物理资源块(physical resource block，PRB)。
终端设备接入小区后，小区网络还可以对终端设备进行单独的配置，对终端设备单独的配置中可以包括终端设备专用的载波配置和带宽部分(bandwidth part，BWP)配置。所述终端设备专用的载波配置包括起始位置和载波宽度，可以用一个信息表示，即所述终端设备专用的载波配置可以为一个。
在5G通信系统中，将终端设备划分为不同能力的终端设备，不同能力的终端设备可能支持不同的载波带宽，即不同能力的终端设备可能支持不同的载波能力。5G在设计之初，能够支持不同载波能力的终端设备能够在同一个大的带宽中工作，该机制可以通过终端设备专用的载波配置和BWP配置实现。目前5G通信系统中只支持为每个终端设备在一个小区载波中配置一个终端设备专用的载波，所述终端设备专用的载波可以小于小区的载波带宽，所述终端设备专用的载波每个终端设备只能配置一个。
5G通信系统中支持载波聚合，终端设备在FR1支持的最大载波带宽为100兆赫兹 (MHz)。其中第三代合作伙伴计划(3rd generation partnership project，3GPP)对5G频率范围进行了定义，包括FR1和FR2，FR1指450MHz-6000MHz，也被称为Sub-6GHz。当频谱带宽超过100MHz时，带宽可以分为多个载波，终端设备通过载波聚合可以使用所有频率带宽，每个载波为一个小区，每个小区均需要广播SSB等信号，因此多载波下会有多个SSB信号的发送，系统开销大。
当前5G新空口(new radio，NR)的R15版本中定义了多种载波带宽，如表1所示。表1中示出了NR频带/频段(Band)包括n1、n2和n3。n1、n2和n3均支持不同的子载波间隔(sub-carrier space，SCS)，例如表1中1、n2和n3均支持15千赫兹(kHz)、30kHz和60kHz的SCS。表1中“Yes”表示NR Band在不同的SCS下支持的带宽，如终端设备UE在频带n1下SCS为15kHz时，支持5MHz、10MHz、15MHz和20MHz，其它参见表1所示，不一一列举说明。
表1
Figure PCTCN2021072579-appb-000041
当前的5G NR的R16版本中增加定义了多种载波带宽如表2所示。相比于R15版本，R16版本中心定义了多种新的带宽，例如在频带n1中，R16版本定义了额外的25MHz、30MHz、40MHz和50MHz带宽选项。R16版本和R15版本的载波带宽其他区别，可以通过表1和表2对比确定，在此不一一列举说明。
表2

Figure PCTCN2021072579-appb-000043
一般的，表1和表2中所示的载波带宽为系统载波带宽，也可以理解为小区载波带宽。
对于支持R15版本的终端设备(这里称为“老终端”/“旧终端”)也需要接入R16的大带宽载波(SIB1中广播的载波带宽和位置)，因此R15中定义了前向兼容的机制。网络设备可以通过信令(如终端设备专用(UE dedicated)信令)给老终端配置新的带宽(包括带宽大小和位置)，使得老终端可以在新网络中的大带宽中进行通信。如图2所示，R16下小区的大带宽载波的系统带宽为50MHz，小区发送SSB信号供老终端初始接入使用，老终端可以在大带宽中进行通信，例如老终端接入小区后，小区为老终端分配的载波带宽为20MHz，然后在为老终端新配置的载波中对所述老终端进行BWP的配置，BWP的配置可以通过下述公式(1)实现。
Figure PCTCN2021072579-appb-000044
其中，
Figure PCTCN2021072579-appb-000045
为275个资源块(resource block，RB)，L RBs为BWP的带宽，所述L RBs小于或等于275，RB start为BWP的起始位置，如起始RB序号，该RB start对应于SIB1中广播的系统载波带宽的第一个RB，RIV为BWP的起始位置和带宽的指示参数。
通过以上设计和配置，小区可以为老终端配置终端设备专用的载波带宽和BWP，老终端设备作为具有小带宽能力的终端设备，也可以在一个大带宽中进行正常的接入和数据收发。
在目前的通信系统中一个基站可能支持大于100MHz的带宽，如图3所示，基站配置了两个载波，例如采用终端设备1专用的信令为终端设备1配置100MHz的载波，采用终端设备2专用的信令为终端设备2配置60MHz的载波。当基站配置了两个载波时，如图4所示，基站可以在每个在载波上单独发送广播信号，例如SSB，系统信息块(system information block，SIB)1，寻呼(paging)，控制资源集(control resource set，CORESET)0等信号。
当一个终端设备在不同的时刻由于某种原因需要从一个载波切换到另一个载波时，目前标准中执行的是载波间切换流程。
每个终端设备只能被配置一个终端设备专用的载波(包括载波起始位置和频域宽度)，因此对于一个大带宽载波，每个终端设备只能在有限的范围内进行通信，如图4所示，终端设备1只能在有限的范围内(如图4中所述终端设备1专用的载波带宽和/或BWP的带宽)，限制所述终端设备1可能使用的频率范围。
因此终端设备可以通过载波聚合的方式使用全部的频谱资源(或称为频率资源)，但是载波聚合是终端设备的一种能力，对于没有这种载波聚合能力的终端设备来说，仍然只能使用分配的第一个载波的资源，终端设备可使用的频率范围仍然受限，这种情况下还可 能会造成第一个载波中的用户数过多，而分配的第二个载波中的用户数较少，造成载波上的负载不均衡。
为了避免上述可能的问题发生，可以在大带宽中只发送一个信号。如图5所示，可以在160MHz的大带宽中只发送一个SSB，以及可以将终端设备2通过终端设备2专用的信令配置一个新的所述终端设备2专用的载波在100M右侧，从而通过一个SSB即可扩大所述终端设备可以使用的频率范围，并且终端设备也不必须具有载波聚合的能力。但是现有的BWP基于RIV配置，计算RIV时采用的RB的个数最大为275，且BWP的起始位置为160MHz的左侧第一个RB，导致终端设备的BWP不能配置在100M的右侧以外，不能实现两个载波共享一个SSB的目的，因此无法很好解决上述问题。
基于此，为了提高终端设备可使用的频率范围，本申请提出一种BWP的确定方法，本申请实施例提供的BWP的确定方法可以应用于如图1所示的通信系统中。在该方法中，终端设备可以在大于275个RB的载波带宽内确定BWP，终端设备可使用的频率范围提高，或者终端设备可以确定BWP的起始位置与终端设备专用的载波带宽有关，这样可以将BWP配置在系统载波带宽以外。因此充分利用网络设备的大带宽特性，在大带宽内网络设备可以只发送一个广播信息，节省系统广播信息的开销，提升了频谱利用率，提升通信系统容量。
实施例一：
在该实施例一中，所述终端设备可以在大于275个RB的载波带宽内确定BWP。下面参考图6，详细说明BWP的确定方法的具体过程，该过程包括：
S601：终端设备获取第一带宽参数、第二带宽参数和第三带宽参数。
所述第一带宽参数为所述BWP的带宽范围，即所述第一带宽参数用于表示/指示所述BWP的带宽范围，也就是说所述第一带宽参数为所述终端设备的BWP可用的最大带宽范围。所述BWP的带宽范围可以为所述BWP的带宽值，所述BWP可用的最大带宽范围也可以为所述BWP的最大带宽值。所述第一带宽参数可以为上述

后者可以为引入的新的带宽参数如
Figure PCTCN2021072579-appb-000047
所述BWP的带宽范围大于275个RB，或所述BWP的带宽值大于275个RB。
一种可能的方式中，所述BWP的带宽范围可以为固定范围/固定值，例如所述BWP的带宽范围为275的倍数，如可以为530，550，825，1100，1375，1650，1925，2200，2475等275倍数中的一个，或为550到500之间的整数，可以使得支持100M终端的用户支持接近200M带宽的频率共享一个SSB。可选的，网络设备可以直接配置所述第一带宽范围为固定范围/固定数值。或者可选的，所述网络设备可以配置所述第一带宽范围为所述终端设备当前接入小区(也称当前小区)的载波带宽，所述终端设备当前接入小区的载波带宽为固定范围/固定数值。所述终端设备当前接入小区的载波带宽为小区的公共带宽或为公共广播消息(如SIB1)中广播的公共带宽。

Figure PCTCN2021072579-appb-000048
而在本申请实施例中所述第一带宽参数大于275个RB，在大于275个RB的载波带宽内确定UE的BWP，终端设备可使用的频率范围提高，在一个大于275个RB的频率资源范围内可以只发送一个广播信息，从而降低公共广播信息的开销。

Figure PCTCN2021072579-appb-000049
目前标准中maxNrofPhysicalResourceBlocks为275个RB。在本申请实施例中，所述网络设备可以将FrequencyInfoDL-SIB消息中的maxNrofPhysicalResourceBlocks扩展为大于为275的数字，例如扩展后的数值可以为530，550，825，1100，1375，1650，1925，2200，2475等275倍数中的一个或为500到550之间的整数。通过配置更大的PRB的个数，网络设备能够配置更宽的系统载波带宽。
目前标准中基站通过BWP信息配置终端设备的BWP，例如BWP信息如下所示，其中locationAndBandwidth用于配置BWP的位置和带宽，cyclicPrefix用于配置BWP是否使用扩展循环前置，subcarrierSpacing用于配置BWP的子载波间隔：

所述第二带宽参数为所述BWP的带宽，所述BWP的带宽小于或等于所述BWP的带宽范围。即所述BWP的带宽为所述BWP的实际带宽，即为所述终端设备配置的BWP的带宽。所述第二带宽参数可以为上述L RBs。
所述第三带宽参数为所述BWP的起始位置，所述第三带宽参数可以为上述RB start。所述BWP的起始位置可以与系统载波带宽的起始位置相关，或者所述BWP的起始位置可以与所述终端设备专用的载波带宽的起始位置相关。例如所述BWP的起始位置为BWP的参考起始位置与偏移量的和确定，或所述BWP的起始位置为BWP的第一个PRB在载波带宽中的位置，所述BWP的参考起始位置可以与系统载波带宽的起始位置相关或者可以与所述终端设备专用的载波带宽的起始位置相关。在本申请实施例中所述终端设备专用的载波带宽指配置给所述终端设备使用的载波带宽，即采用所述终端设备的专用信令配置的载波带宽。
S602：所述终端设备根据第一带宽参数、第二带宽参数和第三带宽参数，确定所述终端设备的BWP的起始位置和带宽。

实施例二：
在该实施例二中，所述终端设备可以确定BWP的起始位置与终端设备专用的载波带宽有关。下面参考图7，详细说明BWP的确定方法的具体过程，该过程包括：
S701：终端设备获取第一带宽参数、第二带宽参数和第三带宽参数。
所述第一带宽参数为所述BWP的带宽范围。所述第二带宽参数为所述BWP的带宽，所述BWP的带宽小于或等于所述BWP的带宽范围。所述第一带宽参数和所述第二带宽参数的配置可以参见上述实施例一，相似之处不做赘述。
所述第三带宽参数用于指示所述BWP的起始位置，所述BWP的起始位置与所述UE专用的载波带宽的起始位置相关。可选的，所述网络设备配置所述终端设备的BWP时，配置所述终端设备的BWP的参考起始位置为ServingCellConfigCommon/ServingCellConfigCommonSIB中配置的载波的起始位置。目前标准中所述BWP的参考起始位置为系统载波的起始位置。在本申请实施例中，所述BWP的参考起始位置为所述终端设备专用的载波带宽起始位置。
所述终端设备专用的载波带宽的频率范围与所述终端设备当前接入小区的载波带宽的频率范围可以完全重叠、或者可以部分重叠、或者可以不重叠。可选的，所述网络设备可以通过所述终端设备的专用信令配置所述终端设备专用的载波带宽。例如所述网络设备可以通过ServingCellConfig/downlinkChannelBW-PerSCS-List配置所述终端设备占用的载波带宽：
Figure PCTCN2021072579-appb-000090
Figure PCTCN2021072579-appb-000091
S702：终端设备根据第一带宽参数、第二带宽参数和第三带宽参数，确定所述终端设备的BWP的起始位置和带宽。
所述S702的过程可以参见上述S601，相似之处不做赘述。
在该实施例二中，BWP的起始位置与终端设备专用的载波带宽有关，可以将终端设备的BWP配置在SIB1广播的载波带宽以外，如图8所示。
如果一个载波能够支持160MHz的大带宽，而终端设备仅能支持100MHz的大带宽，而不能支持160MHz的大带宽，根据目前标准，网络设备仅可以在100MHz范围内为终端设备配置一个载波，或基站支持一个大的带宽，而终端只支持一个小的带宽的场景，如图9所示，终端设备只能使用一个小的带宽。终端设备可使用的载波带宽受限，并且终端设备只能在配置的载波上收发信息，而不能在配置的载波以外，160MHz之内的频率资源上收发数据，因此降低了通信系统的灵活性以及该终端设备与其他终端设备进行多用户-多输入多输出(multi-user multiple-input multiple-output，MU-MIMO)配对的概率，降低了频段内负载均衡的灵活性，并且终端设备不能利用配置的载波带宽以外的频点，降低了终端设备的频率分集的性能。
基于此，本申请实施例还提供了实施例三。
实施例三：
在该实施例三中，网络设备可以为终端设备配置多个载波带宽。下面参考图10，详细说明BWP的确定方法的具体过程，该过程包括：
S1001：网络设备发送第一信令，所述第一信令用于为终端设备配置多个载波带宽，其中所述终端设备专用的载波带宽包括所述多个载波带宽。
可选的，所述多个载波带宽为所述终端设备在一个小区中的多个专用载波。例如所述多个载波带宽为所述终端设备在当前接入小区中的多个专用载波。所述多个载波带宽宽度可以相同或不同。
可选的，所述多个载波带宽宽度相同。
可选的，所述多个载波带宽的子载波间隔相同。
可选的，所述多个载波带宽在频域上为连续的子载波构成。
可选的，所述多个载波带宽在频域上为连续频率。
可选的，所述第一信令还用于配置多个BWP，其中每个载波带宽包括一个或多个BWP。
可选的，所述每个载波带宽的频率范围不重叠，每个BWP属于一个载波带宽，即每 个BWP不跨载波带宽。
可选的，不同专用载波带宽所包含的BWP为镜像BWP。
可选的，不同专用载波带宽中所包含的部分或全部BWP为同一个BWP配置的复制。
可选的，不同专用载波带宽所包含的BWP的参数部分相同或全部相同。
可选的，不同专用载波带宽所包含的BWP的参数部分统一配置。可选的，不同载波带宽内的BWP起始位置与所属载波带宽的起始位置的距离相同。
在一种可能的方式中，所述第一信令中配置有多个downlinkChannelBW-PerSCS-List，并且所述第一信令中配置多个BWP。
在一种可能的方式中，BWP与downlinkChannelBW-PerSCS-List相关联。
另一种可能的方式中，所述第一信令中配置多个BWP，每个BWP中增加载波的配置信息，例如在每个BWP中配置downlinkChannelBW-PerSCS-List字段，以说明该BWP所属的载波的位置，终端设备可以调整发射机的滤波器等特性进行收发信息。
S1002：所述终端设备接收所述第一信令。
可见在本申请实施例三中，小带宽的终端设备可以利用大带宽内的频率资源，达到频率分集的效果，提高单终端设备的吞吐量，且小带宽的终端设备可以在大带宽频率资源内传输，利于多用户时的终端设备配对，以及大带宽小区内的小带宽终端设备可以在大带宽内进行传输利于频率范围内的负载均衡，频率管理更灵活。
可以理解的是，上述实施例一、实施例二和实施例三可以单独使用，也可以结合使用，在本申请实施例中不做限定。
