具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本文中提及的“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。
请参考图1，其示出了本申请一个实施例提供的移动通信系统的结构示意图。该移动通信系统可以包括：接入网设备10和终端20。
接入网设备10部署在无线接入网中用以为终端20提供无线接入功能。接入网设备可以是基站(Base Station，BS)。接入网设备10可以经由一个或多个天线与终端20进行无线通信。接入网设备10可以为其所在地理区域提供通信覆盖。所述基站可以包括宏基站，微基站，中继站，接入点等不同类型。在一些实施例中，基站可以被本领域技术人员称为基站收发机、无线基站、接入点、无线收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、节点B(NodeB)、演进的节点B(evolved NodeB，eNB或eNodeB)或者其它一些适当的术语。示例性地，在5G系统中，基站被称为gNB。为方便描述，本申请实施例中，上述为终端20提供无线通信功能的装置统称为接入网设备。
终端20可以散布于整个移动通信系统中，并且每个终端20可以是静止的 或者移动的。终端20还可以被本领域技术人员称为移动站、用户站、移动单元、用户单元、无线单元、远程单元、移动设备、用户设备、无线设备、无线通信设备、远程设备、移动用户站、接入终端、移动终端、无线终端、远程终端、手持设备、用户代理、移动客户端、客户端或者一些其它适当的术语。终端20可以是蜂窝电话、个人数字助理(Personal Digital Assistant，PDA)、无线调制解调器、无线通信设备、手持设备、平板电脑、膝上型计算机、无绳电话、无线本地环路(Wireless Local Loop，WLL)站等。终端20能够与移动通信系统中的接入网设备10进行通信。

上述图1所示的移动通信系统可以是长期演进(Long Term Evolution，LTE)系统，也可以是基于LTE系统的下一代演进系统，如LTE-A(LTE-Advanced)系统或第五代(5th Generation，5G)系统(又称NR系统)，还可以是基于5G系统的下一代演进系统，等等。本申请实施例中，术语“系统”和“网络”经常被可互换地使用，但本领域技术人员可理解其含义。
本公开实施例描述的通信系统以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信系统的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
在图1所示通信系统中，终端需要利用同步信号块(即同步信号和物理广播信道资源块(Synchronization Signal and PBCH Block，SSB)完成初始接入。
在时域上，一个SSB占用4个符号(也即正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号)，包括：1个符号的主同步信号(Primary Synchronized Signal，PSS)、1个符号的辅同步信号(Secondary Synchronized Signal，SSS)和2个符号的物理广播信道(Physical Broadcast Channel，PBCH)。在SSB内，符号按递增顺序从0到3编号。在频域上，一个SSB占用24个连 续的资源块(Resource Block，RB)。每一个RB包括12个子载波，上述24个RB中的子载波按递增顺序从0到287编号，以编号最低的RB为起始。对于PSS和SSS，资源映射到中间第127个子载波；对于PBCH，资源映射到第288个子载波。PSS、SSS、PBCH具有同样的循环前缀(Cyclic Prefix，CP)长度和子载波间隔。子载波间隔可配置为15kHz、30kHz、120kHz和240kHz。
在初始接入过程中，终端会首先检测接收同步信号块，获取SSB中的主信息块(Master Information Block，MIB)，从MIB中获取终端监听调度其他系统消息(例如系统信息块1(System Information Block 1，SIB1)的物理下行控制信道(Physical Downline Control Channel，PDCCH)的控制资源集合0(COntrol REsource SET0，CORESET0)以及搜索空间(Search Space，SS)的配置。MIB中能够携带的信息较少，分别使用了4个比特来指示不同的CORESET0的配置和SS的配置。根据MIB的指示，终端可以确定CORESET#0相对于同步信号快的频率偏移，以及CORESET0所占据的频率资源大小，即RB的数目。
为了适应不同的通信服务的需求，图1所示通信系统中存在两种终端，分别为第一终端和第二终端。两种终端的能力可以有所不同，示例性地，第二终端所支持的最大传输带宽大于第一终端所支持的最大传输带宽。图2是根据一示例性实施例示出的第一终端和第二终端支持的最大传输带宽的关系示意图。如图2所示，第一终端和第二终端的频道带宽(Channel bandwidth)相同。第二终端支持的最大传输带宽大于第一终端支持的最大传输带宽。
在本公开实施例中，第一终端也可以称为能力缩减新空口设备(reduced Capability NR device)、能力缩减用户设备(reduced Capability UE)或者能力受限用户设备(Capability restricted UE)。示例性地，第一终端可以为工业物联网中的一些传感器，智慧城市中的无线视频监控设备，以及可穿戴设备如手环、手表和健康医疗监控设备等。第二设备也可以称为正常设备。
相关技术中，对于第二终端而言，CORESET0所占据的频率资源大小和指示比特的对应关系由TS38.213中Table13-1到Table13-10给出。例如协议规定，对于最小频道带宽为5MHz或者10MHz的频道，当SCS为15KHz时所能配置的CORESET0的最小频域宽度为24个RB。对于第二终端，在给定频道带宽和SCS下，其支持的最大传输带宽会大于对应的所能配置的CORESET0的最小频域宽度。如果第一终端在给定频道带宽下所支持的最大传输带宽小于第二终端设备，例如为20个RB，如果仍然按照最小频域宽度为24个RB来配置 CORESET0，配置的CORESET0的频域宽度就会超出第一终端的最大传输带宽，影响第一终端对于重要系统消息，例如MIB、SIB1等的接收，从而影响第一终端接入通信系统。
图3是根据一示例性实施例示出的一种配置信息确定方法的流程图。该方法可以由图1中的第一终端执行，参见图3，该方法包括以下步骤：
在步骤301中，第一终端接收MIB；
在步骤302中，第一终端基于MIB确定第一控制资源集合的配置信息，第一控制资源集合的配置信息包括第一控制资源集合的频域宽度，第一控制资源集合的频域宽度小于第二终端的第二控制资源集合的频域宽度，第二控制资源集合的频域宽度是基于该MIB确定的。
在一种可能的实施方式中，MIB包括用于指示第一终端第一控制资源集合的配置信息的第一配置字段和用于指示第二终端第二控制资源集合的配置信息的第二配置字段。
在该实施方式中，通过在MIB中新增第一配置字段，使得第一终端和第二终端可以通过MIB中的不同字段分别获取对应的控制资源集合的配置信息。
在另一种可能的实施方式中，MIB包括用于指示控制资源集合的配置信息的配置字段；
第一终端基于MIB确定第一控制资源集合的配置信息，包括：
第一终端基于第一映射关系，将配置字段的取值对应的控制资源集合作为第一控制资源集合的配置信息，第一映射关系为配置字段的取值与控制资源集合的配置信息的对应关系，第一映射关系中配置字段的取值所对应的控制资源集合的配置信息与第二映射关系中相同配置字段的取值对应的控制资源集合的配置信息不同，第二映射关系用于使所述第二终端基于第二映射关系确定所述第二控制资源集合的配置信息。
在该实施方式中，第一终端和第二终端基于不同的映射关系，由MIB中的同一用于指示控制资源集合的配置信息的配置字段，映射出不同的控制资源集合的配置信息，MIB中无需新增字段，能够满足MIB中所能携带的信息比特数量极端受限的情况。
在另一种可能的实施方式中，第一控制资源集合的频域宽度等于第二终端的第二控制资源集合的频域宽度与宽度差值之差，宽度差值为整数。
在该实施方式中，第一终端可以根据第二控制资源集合的频域宽度与宽度差值计算得到第一控制资源集合的频域宽度。
可选地，MIB包括用于指示控制资源集合的配置信息的配置字段；所述配置字段的不同取值对应的宽度差值相同，或者，所述配置字段的不同取值中至少部分对应的宽度差值不同。

在步骤402中，第一终端基于该第一信令，确定第一控制资源集合的配置信息。
示例性地，该第一信令可以是接入网设备发送给第一终端的。
可选地，第一控制资源集合的配置信息还包括以下的至少一个参数：同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，第一控制资源集合的频率资源与对应的同步信号块的频率偏移值。

值得说明的是，前述步骤401-402与上述可选步骤可以任意组合。
在本公开的一个实施例中，可以通过SSB中的MIB指示第二终端第二控制资源集合的配置信息的第二配置字段，并通过其他任何可行的信令来指示第一终端第一控制资源集合的配置信息的第一配置字段，本公开实施例中并不对此做出限定。

在步骤501中，确定第一信令，其中所述第一信令中至少包括用于指示第一终端的第一控制资源集合的配置信息的第一配置字段和用于指示第二终端第二控制资源集合的配置信息的第二配置字段；所述第一控制资源集合的频域宽度小于第二终端的第二控制资源集合的频域宽度；
在步骤502中，将所述第一信令发送到第一终端。
可选地，第一控制资源集合的配置信息还包括以下的至少一个参数：同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，第一控制资源集合的频率资源与对应的同步信号块的频率偏移值。
可选地，所述第一信令还用于指示物理下行控制信道PDCCH的监听参数。

值得说明的是，前述步骤501-502与上述可选步骤可以任意组合。
在本公开的所有实施例中，可以通过SSB中的MIB指示第二终端第二控制资源集合的配置信息的第二配置字段，并通过其他任何可行的信令来指示第一终端第一控制资源集合的配置信息的第一配置字段，本公开实施例中并不对此做出限定。

在步骤601中，第一终端接收SSB，SSB包括MIB。
MIB中包括用于指示第一终端第一控制资源集合的配置信息的第一配置字段和用于指示第二终端第二控制资源集合的配置信息的第二配置字段。
例如，在以下MIB格式中，pdcch-ConfigSIB1-RestrictUE为第一配置字段，是新增加的专门用于配置第一终端的CORESET0的配置字段，pdcch-ConfigSIB1为第二配置字段，为MIB中的原有字段。其他字段均为MIB中的原有字段。
Figure PCTCN2020075591-appb-000001
在步骤602中，第一终端基于第一配置字段确定第一控制资源集合的配置信息。
通过该步骤602即可实现第一终端基于MIB确定第一控制资源集合的配置信息，第一控制资源集合的配置信息包括第一控制资源集合的频域宽度。第一控制资源集合的频域宽度小于第二终端的第二控制资源集合的频域宽度。第二控制资源集合是基于该MIB确定的，这表示第一终端和第二终端为同一通信系统(例如图1所示通信系统)中的终端。
示例性地，对于相同的频道带宽，第二终端所支持的最大传输带宽大于第一终端所支持的最大传输带宽。
可选地，第一控制资源集合的配置信息还可以包括以下的至少一个参数：同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，第一控制资源集合的频率资源与对应的同步信号块的频率偏移值。
可选地，该步骤602可以包括：

可选地，第一控制资源集合的频域宽度等于第二终端的第二控制资源集合的频域宽度与宽度差值之差，宽度差值为整数。
可选地，该方法还可以包括：第一终端基于MIB确定PDCCH的监听参数。
可选地，第一终端和第二终端基于主信息块MIB确定出的PDCCH的监听参数相同或者不同。
可选地，所述PDCCH的监听参数包括以下的至少一个参数：初始符号位置、时隙的位置、一个时隙中搜索空间的数量。
在本公开实施例中，第一终端基于MIB确定出的第一控制资源集合的频域宽度小于基于该MIB确定出的第二终端的第二控制资源集合的频域宽度，使得第一终端能够在较小的频域宽度上完成对第一控制资源集合相关的系统信息的检测和接收，降低了对第一终端的能力要求，便于第一终端接入通信系统。
并且，在第一终端所支持的最大传输带宽小于第二终端所支持的最大传输带宽时，第一终端基于MIB确定出的第一控制资源集合的频域宽度小于第二终端基于MIB确定出的第二控制资源集合的频域宽度，可以保证第一终端对第一控制资源集合相关的系统信息的正常接收。
此外，通过在MIB中新增用于指示所述第一终端所述第一控制资源集合的配置信息的第一配置字段，使得MIB中同时包括用于指示所述第一终端所述第一控制资源集合的配置信息的第一配置字段和用于指示所述第二终端所述第二控制资源集合的配置信息的第二配置字段，从而第一终端和第二终端可以通过MIB中的不同字段分别获取对应的控制资源集合的配置信息，实现方式简单。

在步骤702中，向第一终端发送所述SSB，其中所述SSB包括MIB，且所述MIB中至少包括用于使所述第一终端基于第一配置字段确定第一控制资源集合的配置信息。
通过上述实施例可以生成第一终端用于确定第一控制资源集合的配置信息的MIB，并通过SSB发送给第一终端。其中，第一控制资源集合的配置信息包括第一控制资源集合的频域宽度。第一控制资源集合的频域宽度小于第二终端的第二控制资源集合的频域宽度。第二控制资源集合是基于该MIB确定的，这表示第一终端和第二终端为同一通信系统(例如图1所示通信系统)中的终端，对于相同的频道带宽，第二终端所支持的最大传输带宽大于第一终端所支持的最大传输带宽。
可选地，第一控制资源集合的配置信息包括以下至少一个参数：同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，以及第一控制资源集合的频率资源与对应的同步信号块的频率偏移值。
可选地，该步骤702可以包括：
向第一终端发送所述SSB，其中所述SSB包括MIB，且所述MIB中至少包括用于使所述第一终端基于第一配置字段确定第一控制资源集合的配置信息，以使所述第一终端基于所述第一配置字段的取值与控制资源集合的对应关系，确定所述第一控制资源集合的配置信息。该对应关系可以是协议规定的。
可选地，第一控制资源集合的频域宽度等于第二终端的第二控制资源集合的频域宽度与宽度差值之差，宽度差值为整数。
可选地，所述MIB还用于指示PDCCH的监听参数。
可选地，所述第一终端和所述第二终端基于所述主信息块MIB确定出的PDCCH的监听参数相同或者不同。
可选地，所述PDCCH的监听参数包括以下至少一个参数：初始符号位置、时隙的位置，以及一个时隙中搜索空间的数量。
在本公开实施例中，在第一终端所支持的最大传输带宽小于第二终端所支持的最大传输带宽时，使得第一终端基于MIB确定出的第一控制资源集合的频域宽度小于第二终端基于MIB确定出的第二控制资源集合的频域宽度，保证第一终端对第一控制资源集合相关的系统信息的正常接收。
此外，通过在MIB中新增用于指示所述第一终端所述第一控制资源集合的配置信息的第一配置字段，使得MIB中同时包括用于指示所述第一终端所述第一控制资源集合的配置信息的第一配置字段和用于指示所述第二终端所述第二控制资源集合的配置信息的第二配置字段，从而第一终端和第二终端可以通过MIB中的不同字段分别获取对应的控制资源集合的配置信息，实现方式简单。
在本公开的所有实施例中，可以通过SSB中的MIB指示第二终端第二控制资源集合的配置信息的第二配置字段，并通过其他任何可行的信令来指示第一终端第一控制资源集合的配置信息的第一配置字段，本公开实施例中并不对此做出限定。
图8是根据一示例性实施例示出的一种配置信息确定方法的流程图。该方法可以由前述第一终端执行，参见图8，该方法包括以下步骤：
在步骤801中，第一终端接收SSB，SSB包括MIB。
MIB中包括用于指示控制资源集合的配置信息的配置字段。示例性地，MIB的格式可以为步骤601所示例子去除第一配置字段后的格式。
在步骤802中，第一终端基于第一映射关系，将该配置字段的取值对应的控制资源集合作为第一控制资源集合的配置信息，第一映射关系为配置字段的取值与控制资源集合的配置信息的对应关系，第一映射关系中配置字段的取值所对应的控制资源集合的配置信息与第二映射关系中相同配置字段的取值对应的控制资源集合的配置信息不同，第二映射关系用于使所述第二终端基于第二映射关系确定所述第二控制资源集合的配置信息。
这里，第二控制资源集合是基于该MIB确定的，这表示第一终端和第二终端为同一通信系统(例如图1所示通信系统)中的终端。
示例性地，对于相同的频道带宽，第二终端所支持的最大传输带宽大于第一终端所支持的最大传输带宽。
通过该步骤802可以实现第一终端基于所述主信息块MIB确定第一控制资源集合的配置信息。
可选地，所述第一控制资源集合的配置信息还包括以下的至少一个参数：同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，第一控制资源集合的频率资源与对应的同步信号块的频率偏移值。
在现有NR协议中，第二终端通过接收MIB得到controlResourceSetZero信息(即配置字段中用于指示CORESET0的配置的4个比特的取值)，通过TS38.213中Table 13-1到13-10映射得到不同的controlResourceSetZero取值对应的SSB与COREST0之间的复用关系、CORESET0的频域宽度、CORESET0的时域symbol数目、和CORESET0的频率资源与对应SSB的频率偏移值等信息。也就是说，第二映射关系包括Table 13-1到13-10。
在本公开实施例中，可以为第一终端配置与TS38.213中Table 13-1到13-10不同的表作为第二映射关系，使得对于该配置字段的相同取值(index)，第一终端所对应的CORESET0的频域宽度小于第二终端对应的CORESET0的频域宽度。这里，频域宽度即RB的数量。
在本公开实施例中，对于同一controlResourceSetZero取值，第一控制资源集合的配置信息中的其他参数(即前述同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，第一控制资源集合的频率资源与对应的同步信号块的频率偏移值)中的部分或者全部参数可以设置为与第二控制资源集合的配置信息中对应参数不同，即具有不同的值，以适应第一终端的需求。例如对于SSB和CORESET0的复用方式1的情况下，CORESET0的频率资源应该包 括SSB所占据的频率资源，CORESET0和SSB之间的频率偏移值设置可以进行适当的调整以适应带宽宽度的变化。
例如，对应表13-1，新增加表13-1a定义第一终端在相同的取值下新的CORESET0的配置信息。
表13-1:对于最小信道带宽为5MHz或者10MHz的频带，{SS/PBCH块，PDCCH}子载波间隔为{15，15}kHz时，Type0-PDCCH搜索空间集合的CORESET的资源块和时隙符号集合。

表13-1a:对于最小信道带宽为5MHz或者10MHz的频带，{SS/PBCH块，PDCCH}子载波间隔为{15，15}kHz时，Type0-PDCCH搜索空间集合的CORESET的资源块和时隙符号集合，仅用于能力受限UE。
Figure PCTCN2020075591-appb-000004
在表13-1中，取值0对应的第二控制资源集合的配置信息为：SSB和CORESET的复用关系为1，CORESET0的频域宽度为24个RB，符号数目为2，第一控制资源集合的频率资源与对应的SSB的频率偏移值为0。在表13-1a中，取值0对应的第一控制资源集合的配置信息为：SSB和CORESET的复用关系为1，CORESET0的频域宽度为20个RB，符号数目为2，第一控制资源集合的频率资源与对应的SSB的频率偏移值为0。可见，取值为0时，第一控制资源集合的频域宽度小于第二控制资源集合的频域宽度，第一控制资源集合的配置信息中的其他参数与第二控制资源集合的配置信息中的其他参数的值相同。
在表13-1中，取值1对应的第二控制资源集合的配置信息为：SSB和 CORESET的复用关系为1，CORESET0的频域宽度为24个RB，符号数目为2，第一控制资源集合的频率资源与对应的SSB的频率偏移值为2。在表13-1a中，取值1对应的第一控制资源集合的配置信息为：SSB和CORESET的复用关系为1，CORESET0的频域宽度为20个RB，符号数目为2，第一控制资源集合的频率资源与对应的SSB的频率偏移值为0。可见，取值为0时，第一控制资源集合的频域宽度小于第二控制资源集合的频域宽度，第一控制资源集合的配置信息中的其他参数中，第一控制资源集合的频率资源与对应的SSB的频率偏移值与第二控制资源集合的频率资源与对应的SSB的频率偏移值不同，SSB和CORESET的复用关系和符号数目相同，也即是，第一控制资源集合的配置信息中的其他参数中，部分参数与第二控制资源集合的配置信息中对应参数的值不同。
需要说明的是，上述仅以表13-1中的部分表项为例，对第一映射关系和第二映射关系的不同进行了示例性说明，本公开实施例并不以此为限，配置字段的各个取值对应的参数值，可以根据实际需要设置。
在本公开实施例中，第一终端基于MIB确定出的第一控制资源集合的频域宽度小于基于该MIB确定出的第二终端的第二控制资源集合的频域宽度，使得第一终端能够在较小的频域宽度上完成对第一控制资源集合相关的系统信息的检测和接收，降低了对第一终端的能力要求，便于第一终端接入通信系统。
并且，在第一终端所支持的最大传输带宽小于第二终端所支持的最大传输带宽时，第一终端基于MIB确定出的第一控制资源集合的频域宽度小于第二终端基于MIB确定出的第二控制资源集合的频域宽度，可以保证第一终端对第一控制资源集合相关的系统信息的正常接收。
此外，由于MIB中所能够携带的信息比特数是极端受限的，MIB中字段的增加会造成很大的标准影响，也会影响以往NR用户设备对系统消息的接收。该实施例中，对于MIB中配置字段的相同取值，第一终端和第二终端使用不同的映射关系，得到不同的控制资源集合的配置信息，无需改变MIB中原有的字段，从而避免了相应的不良影响。
图9是根据一示例性实施例示出的一种配置信息确定方法的流程图。该方法可以由前述第一终端执行，参见图9，该方法包括以下步骤：
在步骤901中，第一终端接收SSB，SSB包括MIB。
MIB中包括用于指示控制资源集合的配置信息的配置字段。示例性地，MIB的格式可以为步骤601所示例子去除第一配置字段后的格式。
在步骤902中，第一终端确定该配置字段的取值对应的宽度差值以及第二控制资源集合的配置信息。
在本公开实施例中，宽度差值为整数，例如，为4。需要说明的是，宽度差值的具体数值可以根据实际需要设置，本公开对此不做限制。
第二控制资源集合的配置信息包括第二控制资源集合的频域宽度。
在步骤903中，第一终端基于该宽度差值和第二控制资源集合的配置信息，确定第一控制资源集合的配置信息。
第一控制资源集合的配置信息包括第一控制资源集合的频域宽度。
可选地，所述第一控制资源集合的配置信息还包括以下的至少一个参数：同步信号块与控制资源集合的复用关系，第一控制资源集合的符号数目，第一控制资源集合的频率资源与对应的同步信号块的频率偏移值。
示例性地，在该步骤903中，可以将第二终端的第二控制资源集合的频域宽度与宽度差值之差作为第一控制资源集合的频域宽度，使得第一控制资源集合的频域宽度小于第二终端的第二控制资源集合的频域宽度；将第二控制资源集合的配置信息中除了第二控制资源集合的频域宽度之外的其他参数作为第一控制资源集合的配置信息中除了第一控制资源集合的频域宽度之外的其他参数。
在本公开实施例中，对于相同的频道带宽，所述第二终端所支持的最大传输带宽大于所述第一终端所支持的最大传输带宽。
通过该步骤902至步骤903即可实现第一终端基于所述主信息块MIB确定第一控制资源集合的配置信息。
在一种可能的实施方式中，所述配置字段的不同取值对应的宽度差值相同，也即是，不同宽度差值的取值为固定值。
在另一种可能的实施方式中，所述配置字段的不同取值中至少部分对应的宽度差值不同。在该实施方式中，配置字段的取值与宽度差值的对应关系可以采用列表表示。例如以下配置字段的取值与频域宽度的对应关系表所示，取值为0和1时，对应的频域宽度相同，均为4，而取值为2时，对应的频域宽度为2，与取值为0和1时对应的频域宽度不同。需要说明的是，配置字段的取值与频域宽度的对应关系表中取值的数量仅为示例，本公开实施例并不以此为限。

在本公开实施例中，第一终端基于MIB确定出的第一控制资源集合的频域宽度小于基于该MIB确定出的第二终端的第二控制资源集合的频域宽度，使得第一终端能够在较小的频域宽度上完成对第一控制资源集合相关的系统信息的检测和接收，降低了对第一终端的能力要求，便于第一终端接入通信系统。
并且，在第一终端所支持的最大传输带宽小于第二终端所支持的最大传输带宽时，第一终端基于MIB确定出的第一控制资源集合的频域宽度小于第二终端基于MIB确定出的第二控制资源集合的频域宽度，可以保证第一终端对第一控制资源集合相关的系统信息的正常接收。
此外，由于MIB中所能够携带的信息比特数是极端受限的，MIB中字段的增加会造成很大的标准影响，也会影响以往NR用户设备对系统消息的接收。该实施例中，第一终端可以基于MIB中配置字段确定宽度差值和第二控制资源集合的频域宽度，并根据宽度差值和第二控制资源集合的频域宽度确定第一控制资源集合的频域宽度，无需改变MIB中原有的字段，从而避免了相应的不良影响。在本公开的所有实施例中，可以通过SSB中的MIB指示第二终端第二控制资源集合的配置信息的第二配置字段，并通过其他任何可行的信令来指示第一终端第一控制资源集合的配置信息的第一配置字段，本公开实施例中并不对此做出限定。
示例性地，在图8和/或图9所示的方法中，还可以包括：基于MIB确定PDCCH的监听参数。
可选地，所述PDCCH的监听参数包括以下的至少一个参数：初始符号位置、时隙的位置、一个时隙中搜索空间的数量。
协议规定，第二终端通过接收MIB得到searchSpaceZero信息，通过Table13-11到Table13-15得到不同searchSpaceZero取值对应的终端在CORESET0上监听PDCCH的参数，如初始符号位置、时域时隙的位置、一个 时隙中搜索空间的个数等。
在一种可能的实施方式中，可以对第一终端定义新的和第二终端不同的对应配置字段取值下的PDCCH监听参数。例如，可以对应Table13-11到Table13-15增加对应的表，用于供第一终端根据不同searchSpaceZero取值确定出对应的PDCCH监听参数。在这种情况下，所述第一终端和所述第二终端基于所述主信息块MIB确定出的PDCCH的监听参数可以相同也可以不同。
在另一种可能的实施方式中，第一终端也以基于Table13-11到Table13-15确定MIB中配置字段取值对应的PDCCH监听参数。在这种情况下，所述第一终端和所述第二终端基于所述主信息块MIB确定出的PDCCH的监听参数相同。
图10至图12分别显示了第一终端和所述第二终端的CORESET0的时间频率资源之间的关系。
如图10所示，第一终端和第二终端在相同的时间单元和时域符号上对PDCCH进行监听，第二终端的CORESET0的频域资源包含第一终端的CORESET0的频域资源。也即是，第二终端的CORESET0时间频率资源包含第一终端的CORESET0的时间频率资源，通过接入网设备的调度可以用同一个PDCCH以及对应的PDSCH传输相同的系统消息给两种终端。
如图11所示，第一终端和第二终端在相同的时间单元和时域符号上对PDCCH进行监听，但第二终端的CORESET0的频域资源包含第一终端的CORESET0的频域资源不重合，也即是，第二终端的CORESET0时间频率资源和第一终端的CORESET时间频率资源不重合，那么接入网设备需要分别发送PDCCH以及对应的PDSCH传输系统消息给两种终端。虽然增加了系统开销，不过可以为第一终端定义与第二终端不同的系统消息。
如图12所示，第一终端的PDCCH监听参数和第二终端的PDCCH监听参数不一致，使得第一终端和第二终端在不同的时间单元和时域符号上检测接收PDCCH。在这种情况下，第二终端的CORESET0的时间频率资源和第一终端的CORESET0的时间频率资源不重合，接入网设备需要分别发送PDCCH以及对应的PDSCH传输系统消息给两种终端。虽然增加了系统开销，不过可以为第一终端定义与第二终端不同的系统消息。
