技术领域
本申请涉及通信技术领域，尤其涉及一种资源配置方法及装置。
背景技术
新无线(new radio，NR)系统中，控制资源集合(control resource set,CORESET)用于传输下行物理控制信道(physical downlink control channel,PDCCH)。目前，协议规定了如何配置属于CORESET的频域资源。具体的，第一，CORESET的频域资源是按照资源块组(resource block group，RBG)的粒度进行分配，一个RBG包括6个资源块(resource block,RB)，即CORESET的频域资源包括的RB数为6的整倍数，例如CORESET包括6个RB或12个RB等。第二，分配给CORESET的RBG包括的所有RB，要完全位于CORESET所在的带宽部分(bandwidth part，BWP)范围内，即COREST的频域资源要完全位于其所在的BWP范围内。第三，CORESET的频域资源的起始RB仅能是在索引为6的整倍数的RB上。
根据上面的方法，如果BWP内没有整块的连续的资源，则无法为CORESET配置频域资源，或者可能导致BWP起始或者结束附近的资源不能配置给CORESET，导致资源利用率降低，降低CORESET频域资源配置的灵活性。

具体实施方式
下面结合说明书附图对本申请实施例做详细描述。

本申请实施例中，以终端设备以及网络设备之间的交互为例进行描述，需要说明的是，本申请实施例提供的方法，不仅可以应用于终端设备与网络侧之间的交互，还可以应用于任意两个设备之间的交互中，本申请实施例对此并不限定。
本申请实施例中，终端设备可以简称为终端，为具有无线收发功能的设备或可设置于该设备的芯片。其中，终端设备也可以称为用户设备(user equipment，UE)、接入终端等。在实际应用中，本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业传感器、可穿戴设备、智能监控终端、工业控制(industrial control)中的无线终端等。本申请实施例中，用于实现终端设备的功能的装置可以是终端设备；也可以是能够支持终端设备实现该功能的装置，例如芯片系统，该装置可以被安装在终端设备中或者与终端设备匹配使用。
网络设备：可以是无线网络中各种制式下无线接入设备，也可以称为接入网设备。例如网络设备可以是将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点，又可以称为RAN设备或基站。一些网络设备的举例为：下一代基站(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)等。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。网络设备包括CU和DU时，多个DU可以由 一个CU集中控制。本申请实施例中，用于实现网络设备的功能的装置可以是网络设备；也可以是能够支持网络设备实现该功能的装置，例如芯片系统，该装置可以被安装在网络设备中或者与网络设备匹配使用。
首先对本申请可能涉及的技术术语进行简单介绍，这些关于术语的介绍只是作为示例，并不是对这些术语的限定。
符号，可以是指正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。
带宽部分(bandwidth part，BWP)：BWP是频域上一段连续的资源。按照传输方向划分，BWP包括上行BWP和下行BWP，上行BWP用于上行传输，下行BWP用于下行传输。上行信道或者信号传输完全在上行BWP内进行，下行信道或者信号传输完全在下行BWP内进行。由于终端设备只能在BWP范围内进行数据传输，因此终端数据传输的参数大都是基于BWP配置的，例如物理层参数、高层参数等。
CORESET，是一个时频资源集合，用于传输下行PDCCH。CORESET在频域上包括个RB、在时域上包括连续个符号。CORESET在频域上是按照RBG的粒度进行分配，一个RBG包括6个RB，即CORESET的频域资源包括的RB数为6的整倍数，例如包括6个RB、12个RB等。
其中，传输PDCCH的资源由一个或多个控制信道元素(control channel element，CCE)聚合构成，传输PDCCH的资源包含的CCE数量就是这个PDCCH的聚合等级(aggregation level，AL)。一个CCE由6个资源单元组(resource element group，REG)组成，每个REG在时域上包括一个符号、在频域上包括一个RB，一个RB在频域上包括12个资源单元(resource element，RE)。如图1所示，示意出一种CORESET包括的资源示意图。图中CORESET包括N个CCE，每个CCE包括6个REG。
网络设备通过比特位图的方式给终端设备配置CORESET的频域资源，具体的，网络设备可以向终端设备发送包括该比特位图的无线资源控制(radio resource control，RRC)消息，该RRC消息中还可以包括CORESET的其他参数，例如CORESET在时域占用的符号数、CORESET的标识等。如图2所示，比特位图中的比特一一对应于不重叠的RBG，CORESET包括的RBG起始于BWP内的第一个RBG，比特位图中的第一个(最左侧/最高位)比特对应于BWP内的第一个RBG(RBG 0)。一个比特如果置为1，则指示该比特对应的RBG属于该CORESET的频域资源，即该RBG分配给了该CORESET。另外，BWP内的第一个RBG的第一个公共资源块(common RB，CRB)的CRB索引为其中，为该BWP的起始频域资源的CRB索引，且该BWP的带宽为个连续的PRB，表示向上取整。完全位于BWP外的RBG以及不完全位于BWP内的RBG(跨BWP边界)，均不能配置给CORESET，即不能完全包含在CORESET所在的BWP内的RBG不能分配给该CORESET。假设图中，RBG 0至RBG 2位于BWP内，RBG 3中的部分RB位于BWP外，如果RBG 0至RBG1配置给CORESET，那么比特位图可以为1100，其中比特位图中的比特按照从左到右依次对应RBG 0至RBG 3。
通过上面的描述可知，分配给CORESET的RB有很多限制条件，导致BWP内很多RB不能够分配给CORESET，导致CORESET中传输的PDCCH受到限制，降低了PDCCH的传输性能，降低了资源利用率。例如，对于支持的最大带宽为5MHz的终端设备，在带宽为5MHz且子载波间隔为30kHz的BWP中，能够分配给CORESET的RB数量最大为6，由于CORESET的时域资源最多包含3个符号，因此最大能支持的PDCCH的聚合等级为2,导致PDCCH的传输性能比较差。
为此，本申请提供一种方法，可以提高CORESET的频域资源分配的灵活性，提高资源利用率，提高PDCCH的传输性能。
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。
本申请中，以网络设备以及终端设备之间交互为例进行说明，网络设备执行的操作也可以由网络设备内部的芯片或模块执行，终端设备执行的操作也可以由终端设备内部的芯片或模块执行。
如图3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，该方法包括：
S301：网络设备确定配置信息。
其中，配置信息用于指示属于控制资源集合的至少一个资源块组，每个资源块组包括X个资源块，X为正整数。举例来说，X为大于0且小于或等于6的整数。例如，X的取值为{1,2,3,6}中的一个。
通过改变每个资源块组包括的资源块数量，使得控制资源集合的频域资源配置的粒度更精细，可以将更多的资源块配置给控制资源集合的频域资源，使得控制资源集合包含的时频资源更多，可以支持更高的PDCCH AL，提升了PDCCH的传输性能。
一种实现方式中，X的取值为预定义的或者为网络设备通过信令配置的。
一种实现方式中，X等于一个资源单元组的频域资源所对应的资源块的个数，或者X等于一个资源单元组集合的频域资源所对应的资源块的个数。资源单元组集合可以是指REG bundle。
例如，一个资源单元组，频域上包括一个RB，时域上包括1个符号，因此每个资源单元组的频域资源对应的资源块的个数可以等于1。例如，PDCCH中的CCE映射到REG时是按照先频域再时域的顺序映射，因此一个资源单元组集合对应的资源块的个数与资源单元组集合包含的资源单元组数量和控制资源集合包含的符号数量有关。示例性地，一个资源单元组集合包含6个资源单元组，控制资源集合包含3个符号，则一个资源单元组集合对应2个资源块；控制资源集合包含2个符号，则一个资源单元组集合对应3个资源块。
一种实现方式中，至少一个资源块组包括至少一个第一资源块组，第一资源块组所包括的X个资源块中的至少一个资源块位于控制资源集合所处的BWP外，这X个资源块中除了上述至少一个资源块之外的资源块(如果存在的情况下)，位于控制资源集合所处的BWP内。
对于第一资源块组，既可以是包括BWP的结束资源块的资源块组，即与BWP的结束资源块交叠的资源块组，也可以是包括该BWP的起始资源块的资源块组，即与BWP的起始资源块交叠的资源块组。如果第一资源块组包括该BWP的起始资源块的资源块组，可以认为是该BWP内的第一个资源块组。
一种实现方式中，至少一个资源块组还包括至少一个第二资源块组，第二资源块组所包括的X个资源块均位于控制资源集合所处的BWP内。
举例来说，如图4所示，图中的RBG 0和RBG 3为第一资源块组，RBG 1和RBG 2为第二资源块组。RBG 0中的3个RB位于BWP外，另外3个RB位于BWP内；同样的，RBG3中的3个RB位于BWP外，另外3个RB位于BWP内。而RBG 1和RBG 2包括的RB均位于BWP内。
另外，对于一个资源块组，其包括的X个资源块均位于控制资源集合所处的BWP外时，该资源块组可以配置给该控制资源集合，也可以不配置给该控制资源集合，本申请对此并不限定。
一种实现方式中，至少一个资源块组中的第一个资源块组中的第一个资源块的公共资源块索引为其中，为BWP的起始资源块的公共资源块索引，表示向下取整。
举例来说，X＝6时，至少一个资源块组中的第一个资源块组中的第一个资源块的公共资源块索引为
由于BWP内的第一个资源块组的第一个资源块的公共资源块索引为导致BWP的起始资源块至公共资源块索引为的资源块不能配置给控制资源集合。通过本申请，为控制资源集合配置的第一个资源块组中的第一个资源块的公共资源块索引为使得BWP的起始资源块至公共资源块索引为的资源块能够配置给控制资源集合，提高了资源利用率。
又一种实现方式中，无论X取值如何，所述至少一个资源块组中的第一个资源块组中的第一个资源块的公共资源块索引均为
其中，为BWP的起始资源块的公共资源块索引，表示向下取整。
通过该方式，不同类型的CORESET共存时，不同类型的CORESET的起始RB都只能在索引为6的整倍数的RB上，可以避免或者降低下行资源碎片化，提高资源利用率。
其中，上面的实现方式可以不依赖于图3的方法流程而独立实施，即只要为终端设备配置控制资源集合时，都可以将属于控制资源集合的第一个资源块组中的第一个资源块的公共资源块索引配置为
一种实现方式中，BWP的起始资源块的公共资源块索引满足：
或者，
其中，表示BWP包括的资源块数量，mod表示取模运算。
举例来说，X＝6时，满足：
又一种实现方式中，无论X取值如何，BWP的起始资源块的公共资源块索引满足：
或者，
其中，表示BWP包括的资源块数量，mod表示取模运算。
通过该实现方式，不同类型的CORESET共存时，不同类型的CORESET的起始RB以及相应的BWP的起始RB或者结束RB都只能在索引为6的整倍数的RB上，可以避免或者降低下行资源碎片化，提高资源利用率。
其中，上面的实现方式可以不依赖于图3的方法流程而独立实施。只要为终端设备配置BWP时，都可以为终端设备配置满足上面公式的起始资源块。
通过这种方法，这样可以保证控制资源集合的起始资源块和BWP的起始资源块的位置是对齐的，或者控制资源集合的结束资源块和BWP的结束资源块的位置是对齐的，避免资源碎片化，实现尽可能利用BWP的频域资源，提高了资源利用率。
一种实现方式中，如果控制资源集合的频率资源包含的资源块数量不再是6的整倍数，控制资源集合中的控制资源单元到资源单元组的映射方式为交织映射时，计算出的交织器的列数可能不是整数，其中，交织器用于将控制资源集合中的控制资源单元映射到资源单元组。为此，本申请中，交织器的列数C可以满足以下形式：
其中，为控制资源集合包括的资源单元组个数，L为一个资源单元组集合对应的资源单元组个数，R为交织器的行数，表示向上取整，交织器用于将控制资源集合中的控制资源单元映射到资源单元组。
举例来说，交织器f(x)可以满足以下形式：
其中，x＝cR+r；r＝0，1，...，R-1；c＝0，1，...，C-1；nshift为偏移值，该偏移值可以为网络设备配置的，也可以为协议预设的值。
其中，上面的实现方式可以不依赖于图3的方法流程而独立实施，即只要控制资源集合的频率资源包含的资源块数量不是6的整倍数时，都可以采用上面的方法确定交织器的列数。
本申请中，配置信息的具体实现方式并不限定。举例来说，配置信息可以为比特位图(bitmap)。比特位图中的每一个比特对应一个资源块组。如果比特位图中的一个比特的取值为1，则该比特对应的资源块组属于控制资源集合的频域资源；如果比特位图中的一个比特的取值为0，则该比特对应的资源块组不属于该控制资源集合的频域资源。
再举例来说，配置信息为比特位图时，比特位图中的每一个比特对应一个资源单元组。如果比特位图中的一个比特的取值为1，则该比特对应的资源单元组的频域资源对应的资源块属于控制资源集合的频域资源；如果比特位图中的一个比特的取值为0，则该比特对应的资源单元组的频域资源对应的资源块不属于该控制资源集合的频域资源。
再举例来说，配置信息为比特位图时，比特位图中的每一个比特对应一个资源单元组集合。如果比特位图中的一个比特的取值为1，则该比特对应的资源单元组集合的频域资源对应的资源块属于控制资源集合的频域资源；如果比特位图中的一个比特的取值为0，则该比特对应的资源单元组集合的频域资源对应的资源块不属于该控制资源集合的频域资源。
S302：网络设备向终端设备发送配置信息；相应的，终端设备接收来自网络设备的配置信息。
具体的，网络设备可以通过RRC消息发送配置信息，也可以通过媒体接入控制(media access control，MAC)控制元素(control element，CE)发送配置信息，本申请对此并不限定。
一种可能的实现方式中，网络设备也可以不发送配置信息，也就是说S302为可选步骤，在该情况下，属于控制资源集合的至少一个资源块组可以通过协议预定义的。
S303：网络设备通过控制资源集合向终端设备发送物理下行控制信道。
本申请中，由于网络设备可以将BWP外的资源块配置给控制资源集合，而终端设备仅支持在BWP内进行通信，因此控制资源集合中的有些资源块中传输的数据可能无法被终端设备接收。此时，有些资源块对于控制资源集合是有效的(valid)，有些资源块对于控制资源集合是无效的(invalid)，终端设备可以通过控制资源集合中的有效资源块接收PDCCH。
本申请中，控制资源集合的有效资源块是指传输PDCCH可用的资源块。或者，对于属于控制资源集合的资源块，如果该资源块能够用于传输PDCCH，即该资源块是用于传输PDCCH的候选资源块， 那么该资源块是控制资源集合中的有效资源块。
相应的，控制资源集合的无效资源块是指不可用于传输PDCCH的资源块。或者，对于属于控制资源集合的资源块，如果该资源块不能够用于传输PDCCH，即该资源块不是用于传输PDCCH的候选资源块，那么该资源块是控制资源集合中的无效资源块。
第一种实现方式中，对于属于控制资源集合的一个资源块组，该资源块组中满足以下条件的资源块为有效资源块：
条件一，资源块位于控制资源集合所处的BWP内；
条件二，资源块对应的资源单元组集合对应连续的L个资源单元组，L为一个资源单元组集合对应的资源单元组个数，L为正整数。
其中，对于属于控制资源集合的一个资源块组，该资源块组中满足上述条件的资源块，也可以称为能够用于传输PDCCH的资源块，或者传输PDCCH的候选资源块等。相应的，对于属于控制资源集合的一个资源块组，该资源块组中不满足以上条件的资源块，也可以称为不能够用于传输PDCCH的资源块，或者传输PDCCH的非候选资源块等。
其中，资源单元组集合是资源控制集合中的CCE到REG映射时的最小粒度。L的取值并不限定，例如L等于2或3或6等。L的取值可以为协议预设的，也可以是网络设备配置的，本申请对此并不限定。
举例来说，以BWP的带宽为5MHz、子载波间隔为30kHz为例，BWP带宽为11个RB，对应的RB索引为0至10。如果为控制资源集合分配12个RB，对应的RB索引为0至11。图5和图6中的每一个小方格代表一个REG，一个REG在频域对应一个RB，在时域对应一个符号。如图5所示，当控制资源集合的时域持续时间为3个符号时，如果L配置为3，那么如图5所示，由于控制资源集合中RB索引为11的RB位于BWP外，因此该RB是无效资源块。图5所示的控制资源集合中，能够用于传输PDCCH的资源块的RB索引为0至10，即有效资源块的RB索引为0至10。由于资源单元组集合对应的RB位于BWP内，因此该控制资源集合包括11个资源单元组集合，即每一行的3个小方格代表一个资源单元组集合，11个资源单元组集合的编号分别为集合#0至集合#10。
如图6所示，当控制资源集合的时域持续时间为3个符号时，如果L配置为6，那么如图6所示，该控制资源集合包括6个资源单元组集合，即每两行的6个小方格代表一个资源单元组集合，6个资源单元组集合的编号分别为集合#0至集合#5。由于控制资源集合中RB索引为11的RB位于BWP外，该RB是无效资源块，因此编号为集合#5的资源单元组集合不能包括该RB，导致编号为集合#5的资源单元组集合只对应3个资源单元组。进一步的，由于编号为集合#5的资源单元组集合对应的资源单元组数量小于6，因此编号为集合#5的资源单元组集合对应的RB是无效资源块。即图6所示的控制资源集合中，能够用于传输PDCCH的资源块的RB索引为0至9，即有效资源块的RB索引为0至9。
第二种实现方式中，对于属于控制资源集合的一个资源块组，该资源块组中满足以下条件一的资源块为有效资源块：
条件一，资源块位于控制资源集合所处的BWP内。
其中，对于属于控制资源集合的一个资源块组，该资源块组中满足上述条件一的资源块，也可以称为能够用于传输PDCCH的资源块，或者传输PDCCH的候选资源块等。相应的，对于属于控制资源集合的一个资源块组，该资源块组中不满足以上条件一的资源块，也可以称为不能够用于传输PDCCH的资源块，或者传输PDCCH的非候选资源块等。
相应的，对于属于控制资源集合的一个资源单元集合，该资源单元集合对应连续的L个资源单元组时，该资源单元集合为有效的资源单元集合；该资源单元集合对应的资源单元组数量小于L时，该资源单元集合为无效的资源单元集合。
举例来说，如前面的图6所示，编号为集合#5的资源单元组集合只对应3个资源单元组，但是该资源单元组集合对应的RB位于BWP内，因此该RB是有效资源块，但是该资源单元集合为无效的资源单元集合。
本申请中，在第一种实现方式和第二种实现方式中，网络设备可以在控制资源集合的有效资源块中传输PDCCH，具体传输PDCCH的过程，本申请对此并不限定，不再赘述。
第三种实现方式中，对于属于控制资源集合的一个资源块组，资源块组中属于控制资源集合的资源块为有效资源块，即该资源块组中的每个资源块均为有效资源块，不论该资源块是否位于BWP外。
该实现方式中，属于控制资源集合的资源块组中的每一个资源块，也可以称为能够用于传输PDCCH的资源块，或者传输PDCCH的候选资源块等。
举例来说，如前面的图5所示，索引为11的资源块虽然位于BWP外，也属于有效资源块，即图5所示的控制资源集合中，有效资源块的索引为0至11，即能够用于传输PDCCH的资源块的索引为0至11对应的资源块。
在第三种实现方式中，网络设备可以只通过控制资源集合中位于BWP内的资源块传输PDCCH对应的数据，也可以通过控制资源集合中位于BWP外的资源块传输PDCCH对应的数据。举例来说，Y为大于1的整数，如果Y个资源块为属于控制资源集合的至少一个资源块组中用于传输PDCCH的资源块，在Y个资源块中包括位于BWP内的资源块和位于BWP外的资源块的情况下，网络设备可以采用以下任一方式通过Y个资源块发送PDCCH对应的数据。
方式一，网络设备将PDCCH对应的数据映射到Y个资源块上，并发送映射到Y个资源块上的数据。
其中，网络设备将PDCCH对应的数据映射到Y个资源块上，是指网络设备将PDCCH承载的下行控制信息，根据所述Y个资源块所包含的资源进行编码和速率匹配，进而将速率匹配后获得的编码比特，按照一定的规则映射到所述Y个资源块上。
在方式一中，无论PDCCH对应的数据映射到BWP内的资源块，还是映射到BWP外的资源块，网络设备均通过该资源块发送映射到该资源块中的PDCCH对应的数据。
该方式可以理解为，无论PDCCH所对应资源块是位于BWP内还是BWP外，或者说位于终端设备的信道带宽内还是终端设备的信道带宽外，网络设备均根据该PDCCH所对应的所有资源块进行编码、速率匹配、加扰、调制、资源映射等，并且会传输完整的PDCCH，或者说，传输该PDCCH所对应的所有资源块中的数据。终端设备可以仅接收位于BWP内的资源块中的PDCCH对应的数据，不接收位于BWP外的资源中的PDCCH对应的数据，即终端采用打孔方式接收、处理该PDCCH。
一种实现方式中，在方式一中，PDCCH是重复传输的，即PDCCH传输次数大于1。对于每次PDCCH重复传输，网络设备均传输完整的PDCCH，虽然在一次PDCCH传输中，终端设备无法接收位于BWP外的资源块中PDCCH对应的数据，但对于不同次重复传输的PDCCH，终端设备可以采用跳频方式接收PDCCH对应的数据，每次接收PDCCH对应的数据的不同部分，这样可以获得额外的编码增益以及频率分集增益，提高PDCCH的传输性能。
一种实现方式中，在方式一中，PDCCH承载的下行控制信息是通过公共无线网络临时标识(radio network temporary identity，RNTI)加扰的，其中公共RNTI包括以下中的至少一项：
寻呼RNTI、系统信息RNTI、随机接入过程中的消息2RNTI、随机接入过程中的消息B RNTI、临时小区RNTI。
方式二，网络设备将PDCCH对应的数据映射到Y个资源块上，并发送映射到Y个资源块中位于BWP内的资源块上的数据。
方式二中，对于位于BWP内的资源块，网络设备通过该资源块发送映射到该资源块中的PDCCH对应的数据；对于位于BWP外的资源块，网络设备虽然将PDCCH对应的数据映射到该资源块中，但最终不发送映射到该资源块中的数据，即将映射到该资源块中的数据进行打孔处理。
该方式可以理解为，无论PDCCH所对应资源块是位于BWP内还是BWP外，或者说位于终端设备的信道带宽内还是终端设备的信道带宽外，网络设备均根据该PDCCH所对应的所有资源块进行编码、速率匹配、加扰、调制、资源映射等，但是仅会传输位于BWP内的资源块中对应的PDCCH数据，不传输位于BWP外的资源中的PDCCH对应的数据，即网络设备采用打孔方式处理、传输该PDCCH。相应地，终端设备也仅接收位于BWP内的资源块中的PDCCH对应的数据，不接收位于BWP外的资源中的PDCCH对应的数据，即终端设备采用打孔方式接收、处理该PDCCH。
一种实现方式中，在方式二中，PDCCH的传输次数等于1，这样可以减少资源消耗，提高资源利用率。
本申请中，网络设备采用方式一或者方式二，使用控制资源集合传输PDCCH时，是根据Y个资源块对PDCCH进行编码和速率匹配的，即在对PDCCH进行编码和速率匹配处理时，对应的资源块数量为Y。
相应地，如果用于传输PDCCH的Y个资源块包括BWP外的资源块，终端设备在使用控制资源集 合接收PDCCH时，终端设备仅在Y个资源块中位于BWP内的资源块中接收PDCCH对应的数据。但是终端设备认为网络设备是根据Y个资源块对PDCCH进行编码和速率匹配的，而不是根据位于BWP内的资源块对PDCCH进行编码和速率匹配的。因此终端设备可以根据Y个资源块对PDCCH进行译码等处理。
S304：终端设备根据配置信息通过控制资源集合接收物理下行控制信道。
通过上面的方法，所述网络设备为控制资源集合配置的每个资源块组包括的资源块数量可以小于6，从而使得更多的资源块可能被配置给控制资源集合；另外，可以为控制资源集合配置包括位于BWP之外的资源块的资源块组，进一步提高了资源配置的灵活性，提高了资源利用率。
如图7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，该方法包括：
S701：网络设备确定配置信息。
一种实现方式中，配置信息用于指示控制资源集合的起始资源块的资源块索引以及控制资源集合的带宽。其中，起始资源块的资源块索引可以为起始资源块的物理资源块索引；网络设备可以通过指示控制资源集合的带宽对应的资源块数量，实现指示控制资源集合的带宽。
一种实现方式中，配置信息用于指示控制资源集合的起始资源块的资源块索引以及控制资源集合的带宽对应的资源块数量的联合编码值。
举例来说，起始资源块的资源块索引为物理资源块索引时，指示信息为资源指示值(resource indication value，RIV)，该RIV的取值可以满足以下形式：
如果则如果则
其中，为控制资源集合所在的BWP的大小(即包括的RB数)，LRB为控制资源集合的带宽对应的资源块数量，RBstart为控制资源集合的起始资源块的物理资源块索引。
S702：网络设备向终端设备发送配置信息；相应的，终端设备接收来自网络设备的配置信息。
S703：网络设备通过控制资源集合向终端设备发送物理下行控制信道。
S704：终端设备根据配置信息通过控制资源集合接收物理下行控制信道。
S702至S704可以参考S302至S304中的描述，在此不再赘述。
通过上面的方法，配置信息可以分别指示控制资源集合的起始资源块的资源块索引以及控制资源集合的带宽，从而可以使得控制资源集合的起始资源块配置的更灵活，提升了控制资源集合频域资源配置的灵活性。
