网络设备，可以是NR系统中的下一代基站(next Generation node B，gNB)，可以是LTE系统中的演进型基站(evolutional node B，eNB)，可以是全球移动通讯(global system of mobile communication，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(nodeB，NB)等。

下面先解释一些本申请涉及的技术术语。
1、子载波：正交频分复用(orthogonal frequency division multiplexing，OFDM)系统中将频域资源划分为若干个子资源，每个频域上的子资源可称为一个子载波。子载波也可以理解为频域资源的最小粒度；
2、子载波间隔：OFDM系统中，频域上相邻的两个子载波的中心位置或峰值位置之间的间隔值。例如，LTE系统中的子载波间隔为15kHz等；NR系统的子载波间隔可以是15kHz，或30kHz，或60kHz，或120kHz，或240kHz等；
NR系统中子载波间隔可通过网络设备配置，例如子载波间隔配置μ＝0对应的子载波间隔为15kHz，子载波间隔配置μ＝1对应的子载波间隔为30kHz，子载波间隔配置μ＝2对应的子载波间隔为60kHz，子载波间隔配置μ＝3对应的子载波间隔为120kHz，子载波间隔配置μ＝4对应的子载波间隔为240kHz等。
3、资源块：频域上连续的N个子载波可称为一个资源块。例如，LTE系统中的一个资源块包括12个子载波，NR系统的一个资源块也包括12子载波。随着通信系统的演进，一个资源块包括的子载波个数也可以是其他值；
4、时隙(slot)：NR系统中，时隙长度和子载波间隔有关。15kHz子载波间隔对应的一个时隙的长度为1ms，30kHz子载波间隔对应的时隙长度为1/2＝0.5ms，60kHz子载波间隔对应的一个时隙的长度为1/4＝0.25ms，120kHz子载波间隔对应的一个时隙的长度为1/8＝0.125ms，240kHz子载波间隔对应的一个时隙的长度为1/16＝0.0625ms。
NR中下行资源调度的基本时间单位是一个时隙(slot)，一般而言，一个slot在时间上由14个OFDM符号组成。在时域上，NR系统中的数据传输被组织成时间长度为10ms的帧(frame),每个帧被分成10个相同大小长度为1ms的子帧(subframe),而每个子帧可包含一个或多个时隙(根据子载波间隔决定，当子载波为15kHz时，每个子帧包含一个时隙)。每个帧由一个系统帧号(System Frame Number，SFN)来标识，SFN的周期等于1024，因此SFN在1024个帧后自行重复。
5、子帧(subframe)：NR系统中一个子帧的时间长度为1ms；
6、半帧(half frame)：NR系统中一个半帧的时间长度为5ms，每个帧可以分为两个半帧，每个半帧包含5个子帧，例如半帧0包含子帧0至子帧4，半帧1包含子帧5至子帧9。
7、帧(frame)：NR系统一个帧的时间长度为10ms，每个帧包括10个子帧。
8、OFDM符号：OFDM系统中时域上最小的时间单元，NR系统中，对于常规循环前缀(normal cyclic prefix)，一个时隙包括14个OFDM符号。
9、BWP：NR标准中提出的新的概念，是网络侧配置给终端设备的一段连续的带宽资源，可实现网络侧和终端设备侧灵活传输带宽配置。
BWP由频域上连续的资源块(resource block，RB)组成，BWP为终端设备带宽内的一个子集。BWP在频域上的最小粒度为1个资源块(resource block，RB)。系统可为终端设备配置一个或多个BWP，且多个BWP在频域上可以重叠(overlap)，如图2所示，基 站为终端设备配置了3个BWP，其中BWP1和BWP2重叠，BWP1和BWP3不重叠。
NR系统中，可以通过BWP配置信息指示BWP。BWP配置信息由基站通过无线资源控制(radio resource control，RRC)信令通知给终端设备。其中，BWP的频域位置是通过位置和带宽(location And Bandwidth)字段进行指示的。通过位置和带宽字段的值可以确定偏置RB start和长度L RBs。最终BWP的起始资源块(resource block，RB)对应的公共资源块的编号为
Figure PCTCN2020107580-appb-000022
O carrier表示BWP所在载波的最低频可用的(lowest usable)子载波相对预设参考点Point A的间隔，该间隔用RB的个数进行表示。
10、控制资源集合(control-resource set,CORESET)：在NR中，PDCCH在一个可配置的控制资源集合(control-resource set,CORESET)上传输。CORESET是用于发送PDCCH的时频资源，一个BWP中可以配置多个CORESET，并且CORESET在频域上不一定要占据整个系统带宽。CORESET类似于LTE系统中一个子帧上用于PDCCH传输的控制区域，但CORESET的时频结构更加灵活。LTE中PDCCH始终占据整个系统带宽，NR的PDCCH不需要跨整个系统带宽，CORESET的这种设计使得NR可以支持不同带宽能力的终端设备，例如，某些终端设备可能不支持非常大的带宽，比如100MHz，并且有益于前向兼容。
目前的标准中，CORESET的频域资源中第一个包含6个RB的组的第一个公共资源块(common resource block，CRB)的索引为
Figure PCTCN2020107580-appb-000023
Figure PCTCN2020107580-appb-000024
为BWP的起始CRB。具体的，如图3所示，BWP起始位置距离BWP内第一个RB组的起始位置间隔X个RB，BWP结束位置距离BWP内最后一个RB组的结束位置间隔Y个RB，如果X和Y都不是6的整数倍，那么有(X+Y)不能配置为CORESET，从而造成资源浪费。
CORESET的频域资源可以通过频域资源(frequencyDomainResources)字段进行指示，频域资源字段为一个长度固定为45的比特位图(bitmap)。该比特位图中的每个比特与一个非重叠且包含6个连续PRB的组一一对应，并以一个下行BWP内的PRB索引递增的顺序进行编号。
11、Point A：用来指示资源块的公共参考点，Point A的位置由网络设备配置。
12、公共资源块(common resource block，CRB)：对于子载波间隔配置μ，CRB从0开始，按照频率由低到高的顺序依次递增编号。对于子载波配置μ，Point A就对应于CRB0的子载波0的中心位置。因此确定了Point A的位置，也就确定了每个CRB的编号。BWP内的每个RB都有对应的CRB编号
Figure PCTCN2020107580-appb-000025
在BWP内，每个RB也有自己的编号，BWP内的RB的编号记为

本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例中，以终端设备和网络设备之间的交互为例进行说明，本申请实施例提 供的方法还可以适用于其他执行主体之间的交互，例如可以是终端设备芯片或模块，与网络设备中的芯片或模块之间的交互，当执行主体为芯片或模块时，可以参考本申请实施例中的描述，在此不再赘述。
结合前面的描述，如图4所示，为本申请实施例提供的一种资源配置方法流程示意图。参见图4，该方法包括：
步骤401：网络设备确定为终端设备配置的BWP。
需要说明的是，网络设备可以为终端设备配置一个或者多个BWP，图4的流程中以一个BWP为例进行说明，不代表只配置了一个BWP。网络设备为终端设备配置其它BWP时，每个BWP的配置以及指示方法相同，在此不再赘述。
步骤402：网络设备向所述终端设备发送第一信息。
其中，所述第一信息用于指示所述BWP的起始RB对应的CRB的编号
Figure PCTCN2020107580-appb-000031
以及所述BWP占用的连续RB的个数L RBs。所述BWP的起始RB对应的CRB的编号
Figure PCTCN2020107580-appb-000032
以及所述BWP占用的连续RB的个数L RBs满足以下条件的一项或者多项：
Figure PCTCN2020107580-appb-000033
Figure PCTCN2020107580-appb-000034
其中，mod为取余运算，K为正整数。
Figure PCTCN2020107580-appb-000035
可以看作是所述BWP的结束RB对应的CRB的编号。L RBs也可以看作是BWP的长度。
进一步可选地，L RBs还可以满足以下条件的一项或者多项：
L RBs小于或者等于L，L为所述终端设备支持的最大传输带宽或者所述终端设备首选(preferred)的工作带宽所包括的连续RB的个数；
L RBsmod K＝0。
需要说明的是，所述K为预设值，或者所述K的取值可以由所述网络设备发送给所述终端设备。K值为预设值时，可选地，K为6。
考虑到后续NR系统中可能会针对低成本物联场景，引入窄带终端设备，或者称为工作带宽受限的终端设备，或者，工作带宽有限的终端设备，网络设备需要结合不同工作带宽的终端设备的控制信道的控制信道元素(control channel element，CCE)占用的RB数，不同工作带宽的终端设备的数据信道在资源分配时采用的资源块组(resource block group，RBG)对应的RB数，来确定一个K值，并通知给终端设备，具体取决于网络设备的实现。以下为几个示例，K的取值可以为CCE占用的RB数以及的RBG对应的RB数中的最小值或者最大值等。网络设备在确定K的取值时采用的原则可以是尽可能避免在资源分配时出现资源碎片，资源碎片即该部分资源既没有分配给窄带终端设备使用，但不能分配给宽带终端设备使用。这里宽带终端设备可以是NR支持增强工作带宽(enhanced mobile broadband,eMBB)业务的终端设备，其工作带宽在FR1最大为100MHz，在FR2最大为400MHz。窄带终端设备可以是工作带宽受限的终端设备，具体带宽限制大小在本实施例中不做限定。例如，带终端设备可以是在FR1小于或者等于20MHz，和/或，在FR2小于或者等于50MHz的终端设备。
需要说明的是，第一信息可以通过RRC信令，或者系统消息，或者媒体接入控制层控制元素MAC CE发送，例如可以通过RRC信令中的位置和带宽(location And Bandwidth)字段携带。
步骤403：终端设备接收来自网络设备的第一信息。
步骤404：终端设备根据所述第一信息确定所述网络设备配置的BWP。
根据上面的方法，在配置BWP时，保证BWP的起始CRB的编号，和/或，BWP包括的最后一个RB对应的CRB的编号为K的整数倍，可以保证更多的RB可被用于CORESET，从而提高资源利用率。
本申请实施例中，第一信息可以为资源指示值(resource indication value，RIV)的索引值，或者第一信息可以为RIV。当然，第一信息也可以存在其他实现方式，本申请实施例并不限定。其中，例如，第一信息为RIV的索引值时，满足上面的条件的RIV的索引值可以依次为0,1,2,…,N-1，其中0表示满足上面的条件的最小RIV的索引值，N-1表示满足上面的条件的最大RIV的索引值，其中N为满足上面的条件的RIV的个数，此时第一信息指示的值可以为0至N-1中的一个。
需要说明的是，其中RIV的确定方式可以如下：
如果

则
Figure PCTCN2020107580-appb-000037
否则

其中，

表示向下取整，L RBs≥1且不超过
Figure PCTCN2020107580-appb-000040
Figure PCTCN2020107580-appb-000041
的取值是预先配置的，例如一般配置
Figure PCTCN2020107580-appb-000042
举例来说，如图5所示，假设RBstart为3，L RBs为10，
Figure PCTCN2020107580-appb-000043
由于
Figure PCTCN2020107580-appb-000044
所以
Figure PCTCN2020107580-appb-000045
当第一信息指示的RIV为2478时，表示BWP的偏置RB start为3，长度L RBs为10。
结合上面的举例，当终端设备根据第一信息确定RIV为2478时，可以根据以下方式确定RB start和L RBs。
步骤一：确定
Figure PCTCN2020107580-appb-000046
的值。
步骤二：如果
Figure PCTCN2020107580-appb-000047
则确定

表示向下取整，
Figure PCTCN2020107580-appb-000054
表示向上取整，mod表示取模运算。
下面结合图6说明如何根据参考点(Point A)、RB start以及L RBs确定BWP。图6中，参考点是预先配置的，RB start和
Figure PCTCN2020107580-appb-000055
可以满足以下关系：
Figure PCTCN2020107580-appb-000056
其中，O carrier表示BWP所在载波的最低频可用的(lowest usable)子载波相对预设参考点的间隔，该间隔用RB的个数进行表示，O carrier的取值也可以预先配置。
从上面的描述可知，根据RB start可以确定BWP的起始RB对应的CRB的编号
Figure PCTCN2020107580-appb-000057
从而可以将从起始RB开始的连续L RBs个RB作为BWP包括的RB。
进一步的，结合前面的描述，如图7所示，以K＝6为例，假设当前存在5个BWP，对应的RIV分别为RIV1至RIV5。其中，根据RIV1和RIV2确定的
Figure PCTCN2020107580-appb-000058
和L RBs满足图4流程中的条件，根据RIV3、RIV4和RIV5确定的
Figure PCTCN2020107580-appb-000059
和L RBs中的至少一项不满足图4流程中的条件。当网络设备需要为终端设备配置多个BWP时，则可以将不满足条件的RIV值剔除，仅配置满足条件的RIV值，从而可以节省信令开销。
需要说明的是，终端设备支持的最大传输带宽或者所述终端设备首选的工作带宽可以为终端设备向网络设备指示的，例如终端设备可以向网络设备发送第三信息，所述第三信 息用于指示所述终端设备支持的最大传输带宽或者所述终端设备首选的工作带宽。第三信息的具体实现方式，本申请实施例并不限定，在此不再赘述。
进一步的，网络设备还可以向终端设备指示在所述BWP中配置的CORESET的频域资源。具体的，如图8所示，为本申请实施例提供的一种资源配置方法流程示意图。参见图8，该方法包括：
步骤801：网络设备确定第二信息；
步骤802：网络设备向终端设备发送第二信息。
其中，所述第二信息用于指示在BWP中配置的CORESET的频域资源。
步骤803：终端设备接收来自网络设备的第二信息；
步骤804：终端设备根据所示第二信息确定在BWP中配置的CORESET的频域资源。
需要说明的是，第二信息可以通过RRC信令发送，例如可以通过RRC信令中的频域资源(frequencyDomainResources)字段携带。
所述第二信息可以为包括至少一个比特的比特位图，该比特位图中的每个比特对应一个RB或者对应一个非重叠且包含6个连续RB的组。例如，如果比特位图中的对应比特为1，则对应的RB组被用于CORESET；如果比特位图中的对应比特为0，则对应的RB组不被用于CORESET。
本申请实施例中，所述第二信息包括的比特数根据所述终端设备支持的最大传输带宽或者所述终端设备首选的工作带宽确定。
举例来说，所述第二信息包括的比特数为
Figure PCTCN2020107580-appb-000060
或者
Figure PCTCN2020107580-appb-000061
或者
Figure PCTCN2020107580-appb-000062
或者
Figure PCTCN2020107580-appb-000063
其中，N为所述终端设备支持的最大传输带宽或者所述终端设备首选的工作带宽所包括的连续RB的个数，
Figure PCTCN2020107580-appb-000064
表示向上取整。
由于第二信息包括的比特数是根据终端设备支持的最大传输带宽或者终端设备首选的工作带宽确定的，相比于现有技术中，第二信息始终按照270个RB进行配置，可以减少第二信息包括的比特数，从而降低信令开销。以低能力(Reduced Capability，REDCAP)终端设备为例，FR1UE支持的最大传输带宽为20MHz，对应的支持的最大传输带宽以RB表述为106个RB。按照上述方式，指示CORESET频域资源的第二信息包括的比特数可以为17比特，相比于现有技术中固定的45比特，能够明显减少信令的开销。
需要说明的是，终端设备支持的最大传输带宽或者所述终端设备首选的工作带宽可以为终端设备向网络设备指示的，例如终端设备可以向网络设备发送第三信息，第三信息的具体实现方式，本申请实施例并不限定，在此不再赘述。本申请实施例中，图4所示的流程和图8所示的流程可以分别单独实施，也可以结合起来实施，本申请实施例对此并不限定。
