Description

频域资源配置方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种频域资源配置方法及装置。
背景技术

Release 18提出了对降低能力(RedCap)终端设备进一步缩减带宽，以支持工厂传感器等数据速率不高且造价敏感的业务类型，同时，仍然可能支持15KHz，30KHz等子载波间隔的配置，导致带宽范围内的可用的频域资源减少。如果仍然采用相关技术中CORESET频域资源的分配方式，可能导致带宽范围内的部分频域资源可能始终得不到利用。

下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了更好的理解本申请实施例公开的一种频域资源配置方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1a，图1a为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个第一网络设备、一个第二网络设备和一个终端设备，图1a所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备和两个或两个以上的终端设备。图1a所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(Long Term Evolution，LTE)系统、第五代移动通信系统、5G新空口系统，或者其他未来的新型移动通信系统等。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101和可以为演进型基站(Evolved NodeB，eNB)、传输点(Transmission Reception Point，TRP)、NR系统中的下一代基站(Next Generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(Wireless Fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(Central Unit，CU)与分布式单元(Distributed Unit，DU)组成的，其中，CU也可以称为控制单元(Control Unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(Mobile Station，MS)、移动终端设备(Mobile Terminal，MT)等，也可以是降低能力终端设备(RedCap UE)、演进的降低能力终端设备(eRedCap UE)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(Mobile Phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、 增强现实(Augmented Reality，AR)终端设备、工业控制(Industrial Control)中的无线终端设备、无人驾驶(Self-Driving)中的无线终端设备、远程手术(Remote Medical Surgery)中的无线终端设备、智能电网(Smart Grid)中的无线终端设备、运输安全(Transportation Safety)中的无线终端设备、智慧城市(Smart City)中的无线终端设备、智慧家庭(Smart Home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
相关技术中，终端设备控制资源集CORESET(Control Resource Set)在时域上占用连续的1至3个符号，在频域上采用类似物理下行共享信道PDSCH(Physical Downlink Shared Channel)资源分配类型0(PDSCHresource allocation type 0)的方式进行频域资源的配置。频域资源分配的基本粒度是6个RB(Resource Block，资源块)。
Release 18中提出了对降低能力(Reduced Capability，RedCap)终端设备进一步缩减带宽，以支持工厂传感器等数据速率不高且造价敏感的业务类型，同时，仍然可能支持15KHz，30KHz等子载波间隔的配置，导致带宽范围内的可用的频域资源减少。
在子载波间隔SCS(sub-carrier spacing)为30KHz时，5MHz的带宽下只有11个可用RB。如果仍然采用相关技术中CORESET频域资源的配置方式，以6个RB为基本粒度进行CORESET频域资源的配置，那么对于物理下行控制信道PDCCH(Physical Downlink Control Channel)来说，带宽范围内的部分频域资源可能始终得不到利用，如图1b所示，图1b为本申请实施例提供的一种相关技术中频域资源配置示意图。这会减少CORESET所包括的REG个数，导致不能支持更高的聚合等级，如图1b所示可支持最高聚合等级AL(Aggregation Level)为2，进而影响终端设备下行传输PDCCH的覆盖和传输性能。
可以理解的是，本申请实施例描述的通信系统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，随着系统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。
下面结合附图对本申请所提供的频域资源配置方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种频域资源配置方法的流程示意图。需要说明的是，本申请实施例的频域资源配置方法由终端设备执行。如图2所示，该方法可以包括如下步骤：
步骤201，接收网络设备发送的第一指示信息。
在本申请实施例中，终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示该终端设备确定控制资源集CORESET占用的频域资源。
可选地，该第一指示信息包括至少1比特，该第一指示信息的每一位比特能够指示对应的一组频域资源单位是否为该CORESET占用的频域资源。
在本申请实施例中，该一组频域资源单位中包括6个频域资源单位。频域资源单位可以为资源块RB，物理资源块PRB(PhysicalResource Block)，虚拟资源块VRB(Virtual Resource Block)，公共资源块CRB(CommonResource Block)等。
步骤202，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外。
在本申请实施例中，终端设备能够根据该第一指示信息确定该CORESET占用的频域资源，其中， 该CORESET占用的频域资源中可以包括在该终端设备支持的带宽之外的频域资源。也就是，该第一指示信息指示的该CORESET资源可以超过该终端设备支持的带宽。
可以理解，在本申请实施例中，该带宽可以是带宽(bandwidth)，也可以是部分带宽(bandwidth part，BWP)。
在一些实施方式中，终端设备能够根据第二指示信息，确定该第一频域资源。也就是，终端设备能够根据该第二指示信息，确定第一指示信息指示的CORESET占用的频域资源中的哪部分频域资源在终端设备支持的带宽之外，以尽量保证PDCCH的传输在终端设备支持的带宽范围之内，提高下行信道的信息传输的可靠性。
可选地，第二指示信息包括以下中的至少一个：PDCCH候选信道(PDCCH candidates)的个数，PDCCH候选信道占用的资源个数，资源粒子组REG(Resource Element Group)捆绑包(REG bundle)中资源粒子组的个数，和资源粒子组REG的循环位移参数。
其中，REG的循环位移参数可以用n shift表示，表示REG在交织映射至CCE时，REG bundle循环位移的位移量。REG捆绑包(REG bundle)中REG的个数可以用REG bundle size表示，可以取值为2,3,6等。REG的循环位移参数和REG bundle中REG的个数能够影响控制信道单元CCE(Control Channel Element)和REG的映射关系。
一个REG在频域上占用一个RB，在时域上占用一个时域符号(symbol)，在CORESET内按照先时域后频域的方式为REG编号，如图3a所示，图3a为本申请实施例提供的一种资源粒子组编号示意图。时域和/或频域上多个连续的REG组成一个REG bundle，一个bundle内的传输采用相同的预编码，也就是说一个bundle内的传输可以进行联合信道估计。一个CCE占用6个REG，可以通过交织和非交织两种方式完成CCE到REG(CCE-to-REG)之间的映射。如图3b，图3c和图3d所示，图3b为本申请实施例提供的一种CCE-to-REG非交织映射示意图，图3c和图3d为本申请实施例提供的一种CCE-to-REG交织映射示意图。交织的映射方式是要经过交织器的交织，如图3c和图3d所示，图3c和图3d中每个REG bundle中REG的个数L为2，交织器的行数R为2，CORESET中包括的REG的个数
Figure PCTCN2022085977-appb-000001
为12，交织器的列数C为3，每个CCE会对应3个REG bundle，图3c中REG的循环位移参数n shift＝0，图3d中REG的循环位移参数n shift＝1。
在一些实施方式中，终端设备能够从REG映射至的至少一个CCE中，根据各CCE的编号，确定目标CCE。能够根据该目标CCE对应的REG频域占用至少一个频域资源单位，确定第一频域资源。
在一些实施方式中，终端设备能够根据物理下行控制信道PDCCH候选信道的个数，确定未映射至PDCCH候选信道的至少一个CCE，确定该未映射至PDCCH候选信道至少一个CCE对应的频域资源单位中，设定个数的频域资源单位在带宽之外。
在一些实施方式中，终端设备将第一指示信息指示的CORESET占用的资源中最低频的频域资源单位，与终端设备支持的带宽中最低频的频域资源单位对齐，或者，将CORESET占用的资源中最高频的频域资源单位，与所述终端设备支持的带宽中最高频的频域资源单位对齐。
综上，通过接收网络设备发送的第一指示信息，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外，终端设备CORESET占用的频域资源允许超过该终端设备支持的带宽，使得终端设备能够尽可能地支持更高的聚合等级，有效提高下行信道的传输性能，增强下行信道的覆盖，提高系统通信效率，有效减少 资源浪费，提高资源利用率。
请参见图4，图4是本申请实施例提供的一种频域资源配置方法的流程示意图。需要说明的是，本申请实施例的频域资源配置方法由终端设备执行。如图4所示，该方法可以包括如下步骤：
步骤401，接收网络设备发送的第一指示信息。
在本申请实施例中，终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示该终端设备确定控制资源集CORESET占用的频域资源。
可选地，该第一指示信息包括至少1比特，该第一指示信息的每一位比特能够指示对应的一组频域资源单位是否为该CORESET占用的频域资源。
在本申请实施例中，该一组频域资源单位中包括6个频域资源单位。频域资源单位可以为资源块RB，物理资源块PRB，虚拟资源块VRB，公共资源块CRB等。
步骤402，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外。
在本申请实施例中，终端设备能够根据该第一指示信息确定该CORESET占用的频域资源，其中，该CORESET占用的频域资源中可以包括在该终端设备支持的带宽之外的频域资源。也就是，该第一指示信息指示的该CORESET资源可以超过该终端设备支持的带宽。
可以理解，在本申请实施例中，该带宽可以是带宽，也可以是部分带宽BWP。
步骤403，从该资源粒子组REG映射至的至少一个控制信道单元CCE中，根据各该CCE的编号，确定目标CCE。
其中，该目标CCE对应的REG频域占用至少一个频域资源单位。
在一些实施方式中，目标CCE是REG映射之后，编号最高的CCE。
在本申请实施例中，根据第一指示信息指示的CORESET占用的频域资源，和网络设备配置的该CORESET时域上占用的符号数，能够确定该CORESET内的至少一个REG。根据REG budle中包括的REG个数(REG bundle size)，交织映射时REG的循环位移参数n shift，交织器的行数等，能够确定该至少一个REG和至少一个CCE之间的映射关系。
可以理解的是，在本申请实施例中，如果REG到CCE之间是非交织映射，且所有REGbundle都能映射到CCE，则在该CORESET占用的频域资源中最高频的频域资源单位的REG必然会对应该映射的至少一个CCE中编号最高的CCE。
如果REG到CCE之间是交织映射，则根据前述相关参数的不同(REG budle中包括的REG个数，交织映射时REG的循环位移参数n shift，交织器的行数等)，REG到CCE的映射方式可能不同。
作为一种示例，请参见图5，图5为本申请实施例提供的一种CCE-to-REG交织映射示意图。如图5所示，该第一指示信息指示该CORESET在频域上占用12个频域资源单位，网络设备配置的该CORESET时域上占用3个符号，REG bundle size＝3，终端设备支持的带宽中包括11个频域资源单位。则频域上一个频域资源单位对应的3个REG为一个REGbundle，按照先时域后频域的方式对CORESET内的REG进行编号，如图5中编号为0,1,2的REG组成REG bundle 0，编号为3,4,5的REG组成REG bundle 1，编号为6,7,8的REG组成REG bundle 2……，该CORESET占用的资源中包括36个REG，12个REG bundle。
若REG的循环位移参数n shift＝1，交织器行数为2，交织映射后则如图5所示，REG bundle 1和REG bundle 7对应CCE#0，REG bundle 2和REG bundle 8对应CCE#1，REG bundle 3和REG bundle 9对应CCE#2，REG bundle 4和REG bundle 10对应CCE#3，REG bundle 5和REG bundle 11对应CCE#4，REG bundle 6和REG bundle 0对应CCE#5。
若REG的循环位移参数n shift＝0，交织器行数为2，交织映射后则如图5所示，REG bundle 0和REG bundle 6对应CCE#0，REG bundle 1和REG bundle 7对应CCE#1，REG bundle 2和REG bundle 8对应CCE#2，REG bundle 3和REG bundle 9对应CCE#3，REG bundle 4和REG bundle 10对应CCE#4，REG bundle 5和REG bundle 11对应CCE#5。
在一些实施方式中，目标CCE是REG映射之后，编号最高的CCE，也就是CCE#5。在该示例中，在REG的循环位移参数n shift＝1的情况下，目标CCE(CCE#5)对应的REG是编号为0,1,2的REG(REG bundle 0)以及编号为18,19,20的REG(REG bundle 6)；在REG的循环位移参数n shift＝0的情况下，目标CCE(CCE#5)对应的REG是编号为15,16,17的REG(REG bundle 5)以及编号为33,34,35的REG(REG bundle 11)。
该目标CCE对应的REG在频域上占用至少一个频域资源单位。在该示例中，在REG的循环位移参数n shift＝1的情况下，该目标CCE对应的REG在频域上占用REG bundle 0和REG bundle 6所在的两个频域资源单位；在REG的循环位移参数n shift＝0的情况下，该目标CCE对应的REG在频域上占用REG bundle 5和REG bundle 11所在的两个频域资源单位。
步骤404，响应于该目标CCE对应的REG频域所在的至少一个频域资源单位中，包括该CORESET占用的频域资源中最低频的频域资源单位，确定至少该最低频的频域资源单位在该终端设备支持的带宽之外。
在本申请实施例中，如果该目标CCE对应的REG频域所在的至少一个频域资源单位中，包括了该CORESET占用的频域资源中最低频的频域资源单位，也就是包括了该第一指示信息指示的频域资源中最低频的频域资源单位，确定至少该最低频的频域资源单位在该终端设备支持的带宽之外。
作为一种示例，如前所述，在该示例中，在REG的循环位移参数n shift＝1的情况下，目标CCE(CCE#5)对应的REG是编号为0,1,2的REG(REG bundle 0)以及编号为18,19,20的REG(REG bundle 6)，该目标CCE对应的REG在频域上占用REG bundle 0和REG bundle 6所在的两个频域资源单位。其中，REG bundle 0所在的频域资源单位，是该CORESET占用的频域资源中最低频的频域资源单位，确定至少该最低频的频域资源单位在该终端设备支持的带宽之外，也就是确定至少该REG bundle 0所在的频域资源单位在该终端设备支持的带宽之外。在该示例中，配置给CORESET的资源在频域上占用12个频域资源单位，该终端设备支持的带宽包括11个频域资源单位，因此，只需要确定1个频域资源单位(该REG bundle 0所在的频域资源单位)在该终端设备支持的带宽之外。
在一些示例中，如果配置给CORESET的资源在频域上占用的频域资源单位个数，与终端设备支持的带宽包括的频域资源单位个数的差值为N(N>1，N为正整数)，则确定按照频率从低到高排序为前N个的频域资源单位在该终端设备支持的带宽之外(其中，必然包括该最低频的频域资源单位)。
步骤405，响应于该目标CCE对应的REG频域所在的至少一个频域资源单位中，包括该CORESET占用的频域资源中最高频的频域资源单位，确定至少该最高频的频域资源单位在该终端设备支持的带宽之外。
在本申请实施例中，如果该目标CCE对应的REG频域所在的至少一个频域资源单位中，包括了该CORESET占用的频域资源中最高频的频域资源单位，也就是包括了该第一指示信息指示的频域资源中最高频的频域资源单位，确定至少该最高频的频域资源单位在该终端设备支持的带宽之外。
作为一种示例，如前所述，在该示例中，在REG的循环位移参数n shift＝0的情况下，目标CCE(CCE#5)对应的REG是编号为15,16,17的REG(REG bundle 5)以及编号为33,34,35的REG(REG bundle 11)，该目标CCE对应的REG在频域上占用REG bundle 5和REG bundle 11所在的两个频域资源单位。其中，REG bundle 11所在的频域资源单位，是该CORESET占用的频域资源中最高频的频域资源单位，确定至少该最高频的频域资源单位在该终端设备支持的带宽之外，也就是确定至少该REG bundle 11所在的频域资源单位在该终端设备支持的带宽之外。在该示例中，配置给CORESET的资源在频域上占用12个频域资源单位，该终端设备支持的带宽包括11个频域资源单位，因此，只需要确定1个频域资源单位(该REG bundle 11所在的频域资源单位)在该终端设备支持的带宽之外。
在一些示例中，如果配置给CORESET的资源在频域上占用的频域资源单位个数，比终端设备支持的带宽包括的频域资源单位个数为N(N>1，N为正整数)，则确定按照频率从高到低排序为前N个的频域资源单位在该终端设备支持的带宽之外(其中，必然包括该最高频的频域资源单位)。
综上，通过接收网络设备发送的第一指示信息，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外，从该资源粒子组REG映射至的至少一个控制信道单元CCE中，根据各该CCE的编号，确定目标CCE，根据该目标CCE对应的REG频域所在的至少一个频域资源单位中，是包括该CORESET占用的频域资源中最低频的频域资源单位，还是包括该CORESET占用的频域资源中最高频的频域资源单位，确定在该终端设备支持的带宽之外的频域资源单位，终端设备CORESET占用的频域资源允许超过该终端设备支持的带宽，使得终端设备能够尽可能地支持更高的聚合等级，有效提高下行信道的传输性能，增强下行信道的覆盖，提高系统通信效率，能够尽量保证下行信道的传输在该终端设备支持的带宽范围之内，提高通信传输的可靠性，有效减少资源浪费，提高资源利用率。
请参见图6，图6是本申请实施例提供的一种频域资源配置方法的流程示意图。需要说明的是，本申请实施例的频域资源配置方法由终端设备执行。如图6所示，该方法可以包括如下步骤：
步骤601，接收网络设备发送的第一指示信息。
在本申请实施例中，终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示该终端设备确定控制资源集CORESET占用的频域资源。
可选地，该第一指示信息包括至少1比特，该第一指示信息的每一位比特能够指示对应的一组频域资源单位是否为该CORESET占用的频域资源。
在本申请实施例中，该一组频域资源单位中包括6个频域资源单位。频域资源单位可以为资源块RB，物理资源块PRB，虚拟资源块VRB，公共资源块CRB等。
步骤602，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外。
在本申请实施例中，终端设备能够根据该第一指示信息确定该CORESET占用的频域资源，其中，该CORESET占用的频域资源中可以包括在该终端设备支持的带宽之外的频域资源。也就是，该第一指 示信息指示的该CORESET资源可以超过该终端设备支持的带宽。
可以理解，在本申请实施例中，该带宽可以是带宽，也可以是部分带宽BWP。
步骤603，根据物理下行控制信道PDCCH候选信道的个数，确定未映射至物理下行控制信道PDCCH候选信道的至少一个控制信道单元CCE。
在本申请实施例中，能够根据物理下行控制信道PDCCH候选信道的个数，确定未映射至PDCCH候选信道的至少一个CCE，进而根据该未映射至PDCCH候选信道的至少一个CCE，确定在终端设备支持的带宽范围之外的频域资源。
若干个CCE会聚合成PDCCH，聚合成PDCCH的CCE个数就是聚合等级AL，所有可能是PDCCH的资源就叫PDCCH候选信道(PDCCH candidate)。
作为一种示例，请参见图7，图7为本申请实施例提供的一种CCE-to-REG交织映射示意图。如图7所示，该第一指示信息指示该CORESET在频域上占用12个频域资源单位，网络设备配置的该CORESET时域上占用3个符号，REG bundle size＝3，终端设备支持的带宽中包括11个频域资源单位。则频域上一个频域资源单位对应的3个REG为一个REGbundle，按照先时域后频域的方式对CORESET内的REG进行编号，如图7中编号为0,1,2的REG组成REG bundle 0，编号为3,4,5的REG组成REG bundle 1，编号为6,7,8的REG组成REG bundle 2……，该CORESET占用的资源中包括36个REG，12个REG bundle。在该示例中，PDCCH候选信道个数为1，聚合等级AL＝4。
在该示例中，该CORESET占用的资源中包括36个REG，每个CCE对应6个REG，因此该CORESET占用的资源中包括6个CCE。在该示例中，PDCCH候选信道个数为1，聚合等级AL＝4，确定CCE#0-CCE#3映射至PDDCH候选信道PDCCH candidate#0，确定未映射至PDCCH候选信道的至少一个CCE为CCE#4和CCE#5。
可以理解的是，在本申请实施例中，该示例仅作为一种示例性示出的方法，确定未映射至PDCCH候选信道的至少一个CCE，还可以根据通信系统以及协议规定，采用其他方式确定PDCCH候选信道中的CCE以及未映射至PDCCH候选信道的至少一个CCE，在此不作限定。
步骤604，确定该未映射至PDCCH候选信道的至少一个CCE对应的频域资源单位中，频率最高设定个数的频域资源单位和/或频率最低设定个数的频域资源单位，在该终端设备支持的带宽之外。
其中，该设定个数是根据该第一指示信息指示该CORESET在频域上占用的频域资源单位个数，和该终端设备支持的带宽中包括的频域资源单位个数确定的。
可以理解，频率最高设定个数是指，按照频率从高至低排序为前设定个数，或者按照频率从低至高排序为后设定个数；频率最低设定个数是指，按照频率从高至低排序为后设定个数，或者按照频率从低至高排序为前设定个数。
在一些实施方式中，该设定个数为，配置给CORESET的资源在频域上占用的频域资源单位个数，与终端设备支持的带宽包括的频域资源单位个数的差值，也就是，该设定个数N＝配置给该CORESET的资源在频域上占用的频域资源单位个数-该终端设备支持的带宽中包括的频域资源单位个数。
作为第一种可能的实施方式，在未映射至PDCCH候选信道的至少一个CCE对应的频域资源单位中，按照频率排序为前N个频域资源单位，在该终端设备支持的带宽之外。可选地，该频率排序可以为从低至高排序，也可以为从高至低排序。
作为第二种可能的实施方式，在未映射至PDCCH候选信道的至少一个CCE对应的频域资源单位 中，按照频率排序为后N个频域资源单位，在该终端设备支持的带宽之外。可选地，该频率排序可以为从低至高排序，也可以为从高至低排序。
作为第三种可能的实施方式，在未映射至PDCCH候选信道的至少一个CCE对应的频域资源单位中，按照频率排序为前m个和后(N-m)个频域资源单位，在该终端设备支持的带宽之外。可选地，该频率排序可以为从低至高排序，也可以为从高至低排序。其中，m为自然数。
作为一种示例，如前所述，在该示例中，若REG的循环位移参数n shift＝1，交织器行数为2，交织映射后则如图7所示，REG bundle 1和REG bundle 7对应CCE#0，REG bundle 2和REG bundle 8对应CCE#1，REG bundle 3和REG bundle 9对应CCE#2，REG bundle 4和REG bundle 10对应CCE#3，REG bundle 5和REG bundle 11对应CCE#4，REG bundle 6和REG bundle 0对应CCE#5。
若REG的循环位移参数n shift＝0，交织器行数为2，交织映射后则如图7所示，REG bundle 0和REG bundle 6对应CCE#0，REG bundle 1和REG bundle 7对应CCE#1，REG bundle 2和REG bundle 8对应CCE#2，REG bundle 3和REG bundle 9对应CCE#3，REG bundle 4和REG bundle 10对应CCE#4，REG bundle 5和REG bundle 11对应CCE#5。
在该示例中，配置给CORESET的资源在频域上占用的频域资源单位个数，与终端设备支持的带宽包括的频域资源单位个数的差值N＝1。
若REG的循环位移参数n shift＝1，未映射至PDCCH候选信道的至少一个CCE(CCE#4和CCE#5)，对应的频域资源单位为REG bundle 5，REG bundle 11，REG bundle 6和REG bundle 0所在的频域资源单位。在该示例中，可以确定REG bundle 0所在的频域资源单位在该终端设备支持的带宽之外，也可以确定REG bundle 11所在的频域资源单位在该终端设备支持的带宽之外。
若REG的循环位移参数n shift＝0，未映射至PDCCH候选信道的至少一个CCE(CCE#4和CCE#5)，对应的频域资源单位为REG bundle 4，REG bundle 10，REG bundle 5和REG bundle 11所在的频域资源单位。在该示例中，确定REG bundle 11所在的频域资源单位在该终端设备支持的带宽之外。
在一些示例中，如果N>1，N为正整数，比如，该终端设备支持的带宽包括10个频域资源单位，则N＝2。若REG的循环位移参数n shift＝1，在该示例中，可以确定REG bundle 0和REG bundle 11所在的频域资源单位在该终端设备支持的带宽之外。若REG的循环位移参数n shift＝0，在该示例中，可以确定REG bundle 10和REG bundle 11所在的频域资源单位在该终端设备支持的带宽之外。
综上，通过接收网络设备发送的第一指示信息，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外，根据物理下行控制信道PDCCH候选信道的个数，确定未映射至物理下行控制信道PDCCH候选信道的至少一个控制信道单元CCE，确定该未映射至PDCCH候选信道的至少一个CCE对应的频域资源单位中，频率最高设定个数的频域资源单位和/或频率最低设定个数的频域资源单位，在该终端设备支持的带宽之外，终端设备CORESET占用的频域资源允许超过该终端设备支持的带宽，使得终端设备能够尽可能地支持更高的聚合等级，有效提高下行信道的传输性能，增强下行信道的覆盖，提高系统通信效率，能够尽量保证下行信道的传输在该终端设备支持的带宽范围之内，提高通信传输的可靠性，有效减少资源浪费，提高资源利用率。
请参见图8，图8是本申请实施例提供的一种频域资源配置方法的流程示意图。需要说明的是，本 申请实施例的频域资源配置方法由终端设备执行。如图8所示，该方法可以包括如下步骤：
步骤801，接收网络设备发送的第一指示信息。
在本申请实施例中，终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示该终端设备确定控制资源集CORESET占用的频域资源。
可选地，该第一指示信息包括至少1比特，该第一指示信息的每一位比特能够指示对应的一组频域资源单位是否为该CORESET占用的频域资源。
在本申请实施例中，该一组频域资源单位中包括6个频域资源单位。频域资源单位可以为资源块RB，物理资源块PRB，虚拟资源块VRB，公共资源块CRB等。
步骤802，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外；该CORESET占用的频域资源中最低频的频域资源单位，与该终端设备支持的带宽中最低频的频域资源单位对齐；或者，该CORESET占用的频域资源中最高频的频域资源单位，与该终端设备支持的带宽中最高频的频域资源单位对齐。
在本申请实施例中，终端设备能够根据该第一指示信息确定该CORESET占用的频域资源，其中，该CORESET占用的频域资源中可以包括在该终端设备支持的带宽之外的频域资源。也就是，该第一指示信息指示的该CORESET资源可以超过该终端设备支持的带宽。
可以理解，在本申请实施例中，该带宽可以是带宽，也可以是部分带宽BWP。
在本申请实施例中，作为第一种可能的实施方式，该CORESET占用的频域资源中最低频的频域资源单位，与该终端设备支持的带宽中最低频的频域资源单位对齐。也就是，该第一指示信息指示的起始的频域资源单位为，该终端设备支持的带宽的频率从低至高的第一个频域资源单位。
作为第二种可能的实施方式，该CORESET占用的频域资源中最高频的频域资源单位，与该终端设备支持的带宽中最高频的频域资源单位对齐。也就是，该第一指示信息指示的终止的频域资源单位为，该终端设备支持的带宽的频率从低至高的最后一个频域资源单位。
综上，通过接收网络设备发送的第一指示信息，根据该第一指示信息，确定控制资源集CORESET占用的频域资源，其中，该CORESET占用的频域资源中的第一频域资源在该终端设备支持的带宽之外；该CORESET占用的频域资源中最低频的频域资源单位，与该终端设备支持的带宽中最低频的频域资源单位对齐，或者，该CORESET占用的频域资源中最高频的频域资源单位，与该终端设备支持的带宽中最高频的频域资源单位对齐，终端设备CORESET占用的频域资源允许超过该终端设备支持的带宽，使得终端设备能够尽可能地支持更高的聚合等级，有效提高下行信道的传输性能，增强下行信道的覆盖，提高系统通信效率，有效减少资源浪费，提高资源利用率。
需要说明的是，因为CORESET#0的资源配置方式与其他CORESET不同，在本申请各实施例中，如果该控制资源集CORESET为CORESET#0，则该第一指示信息为剩余最小系统消息RMSI(Remaining Minimum System Information)，该RMSI信令用于从协议约定的至少一个频域资源长度和对应的符号个数的组合中，确定该CORESET#0的频域资源长度和对应的符号个数。
作为一种示例，当子载波间隔SCS为30KHz时，协议约定的至少一个频域资源长度和对应的符号个数的组合可以如下表所示。
Figure PCTCN2022085977-appb-000002
表1 CORESET#0的频域资源长度和对应的符号个数配置
为了提高资源利用率，减少不必要的资源浪费，同时提高传输效率和质量，在设计CORESET#0的频域资源长度和对应的符号个数的组合时，可以尽量满足该频域资源长度不要超过终端设备支持的带宽，该频域资源长度和对应的符号个数的组合所包括的REG的个数(也就是RB的个数和符号个数的乘积)尽量为6的整数倍等等。
可以理解，该表格只是作为一种示例，示例性地给出一些可能的CORESET#0的频域资源长度和对应的符号个数的组合，还可以设计更多的组合，以满足和适应更多的场景和带宽需要，该表格仅作为一种示例，而不对本申请实施例进行限定。

在本申请实施例中，如果该控制资源集CORESET为CORESET#0，则该第一指示信息为剩余最小系统消息RMSI，该RMSI信令用于从协议约定的至少一个频域资源长度和对应的符号个数的组合中，确定该CORESET#0的频域资源长度和对应的符号个数。
综上，通过向终端设备发送第一指示信息，该第一指示信息，用于确定控制资源集CORESET占用的频域资源；其中，该CORESET占用的频域资源中的第一频域资源在所述终端设备支持的带宽之外，终端设备CORESET占用的频域资源允许超过该终端设备支持的带宽，使得终端设备能够尽可能地支持更高的聚合等级，有效提高下行信道的传输性能，增强下行信道的覆盖，提高系统通信效率，有效减少资源浪费，提高资源利用率。
