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、RMSI)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，CORESET#0)以及搜索空间(Search Space，SS)的配置信息。根据MIB的指示，终端可以确定CORESET#0相对于同步信号块的频率偏移，以及CORESET#0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，第二终端所支持的初始接入带宽部分的带宽大于第一终端所支持的初始接入带宽部分的带宽，也即是，第二终端的接入带宽能力超过第一终端的接入带宽能力。
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)、能力受限用户设备(Capability restricted UE)或者新空口简化设备(NR-lite)。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，例如移动终端等。
图2是根据一示例性实施例示出的一种初始接入带宽部分的确定方法的流程图。该方法可以由前述第一终端执行，参见图2，该方法包括以下步骤：

可选地，所述第一终端基于第一规则确定第一初始接入带宽部分，包括：
若所述第二初始接入带宽部分不超过所述第一终端的接入带宽能力，则将所述第二初始接入带宽部分作为所述第一初始接入带宽部分。
可选地，所述根据控制资源集合0的配置信息确定所述第一初始接入带宽部分，包括：
将所述控制资源集合0所在的频率资源，确定为所述第一初始接入带宽部分；或者，

可选地，所述根据所述第一终端的接入带宽能力，确定所述第二初始接入带宽的部分带宽为所述第一初始接入带宽部分，包括：
将所述第二初始接入带宽部分的起始频率位置作为所述第一初始接入带宽部分的起始位置，并根据所述第一终端的接入带宽能力作为所述起始频率位置的偏移量以确定所述第一初始接入带宽的结束位置。
值得说明的是，前述步骤201与上述可选步骤可以任意组合。
图3是根据一示例性实施例示出的一种初始接入带宽部分的配置方法的流程图。该方法可以由前述接入网设备执行，参见图3，该方法包括以下步骤：
在步骤301中，生成剩余主系统信息RMSI，所述RMSI包括用于指示第二终端的初始接入带宽部分的第一配置信息和用于指示第一终端的初始接入带宽部分的第二配置信息，所述第一终端的接入带宽能力小于所述第二终端的接入带宽能力；
在步骤302中，发送所述RMSI。
图4是根据一示例性实施例示出的一种初始接入带宽部分的确定方法的流程图。该方法可以由图1中的接入网设备和终端共同执行，在图4所示实施例中，终端包括第一终端和第二终端，第一终端的接入带宽能力低于第二终端的接入带宽能力，参见图4，该方法包括以下步骤：
在步骤401中，接入网设备发送CORESET#0的配置信息和RMSI。
CORESET#0的配置信息用于指示CORESET#0所在的频率资源。示例性地，CORESET#0的配置信息可以包括起始频率位置和频域的宽度等信息。
终端可以根据CORESET#0的配置信息可以获取调度系统消息(例如SIB1、RMSI等)的PDCCH。
终端在获取到RMSI关联的PDCCH之后，再获取该PDCCH对应的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，从PDSCH数据中解析出RMSI。
在一种可能的实施方式中，该RMSI中包括用于指示第二终端的初始接入带宽部分的第一配置信息。在另一种可能的实施方式中，该RMSI中不包括该第一配置信息。
在步骤402中，第一终端根据CORESET#0的配置信息确定第一初始接入带宽部分。
在一种可能的实施方式中，该步骤402包括：将CORESET#0所在的频率资源，确定为第一初始接入带宽部分。也即是，将CORESET#0所占的频率大小和频率带宽确定为第一初始接入带宽部分。
在另一种可能的实施方式中，该步骤402包括：将CORESET#0所在的频率资源的起始频率位置作为第一初始接入带宽部分的起始位置，并将第一终端的接入带宽能力作为起始频率位置的偏移量以确定第一初始接入带宽的结束位置。
在步骤403中，第二终端接收CORESET#0的配置信息和RMSI。
在步骤404中，第二终端根据该RMSI确定第二初始接入带宽部分。
在该步骤404中，如果RMSI中包括第一配置信息，则将第一配置信息所指示的初始接入带宽部分作为第二初始接入带宽部分。或者，如果RMSI中不包括第一配置信息，则根据CORESET#0的配置信息，确定第二初始接入带宽部分。也即是，将所述控制资源集合0所在的频率资源，确定为第二初始接入带宽部分。
示例性地，图4所示方法可以用于确定初始下行接入带宽部分。也即是，第一初始接入带宽部分和第二初始接入带宽部分均为初始下行接入带宽部分。
需要说明的是，在图4所示方法中，第一规则为仅根据CORESET#0的配置信息确定第一初始接入带宽部分(参见步骤402)。第二规则为：如果RMSI中包括第一配置信息，则将第一配置信息所指示的初始接入带宽部分作为第二 初始接入带宽部分；如果RMSI中不包括第一配置信息，则根据CORESET#0的配置信息，确定第二初始接入带宽部分(参见步骤404)，也即是，第一规则和第二规则不完全相同。
在本公开实施例中，无论RMSI中是否包含第一配置信息，也无论第一配置信息所指示的初始接入带宽部分是否超过第一终端的接入带宽能力，第一终端均根据CORESET#0的配置信息确定第一初始接入带宽部分，由于CORESET#0所在的频率资源较小，所以根据CORESET#0的配置信息确定出的第一初始带宽部分不会超过第一终端的接入带宽能力，有利于第一终端的正常工作。
图5是根据一示例性实施例示出的一种初始接入带宽部分的确定方法的流程图。该方法可以由前述接入网设备和终端共同执行，在图5所示实施例中，终端包括第一终端和第二终端，第一终端的接入带宽能力低于第二终端的接入带宽能力，参见图5，该方法包括以下步骤：
在步骤501中，接入网设备发送RMSI。
在一种可能的实施方式中，该RMSI包括用于指示第二终端的初始接入带宽部分的第一配置信息和用于指示第一终端的初始接入带宽部分的第二配置信息。在另一种可能的实施方式中，该RMSI包括该第二配置信息，而不包括该第一配置信息。
为了保证第一终端确定出的第一初始接入带宽部分不超过第一终端的接入带宽能力，该第二配置信息指示的初始接入带宽部分不超过第一终端的接入带宽能力。
示例性地，当RMSI中同时包括第一配置信息和第二配置信息时，第二配置信息所指示的初始接入带宽部分小于第一配置信息所指示的初始接入带宽部分。
在步骤502中，第一终端接收该RMSI。
在步骤503中，第一终端根据该第二配置信息确定第一初始接入带宽部分。
也即是，将第二配置信息所指示的初始接入带宽部分，作为该第一初始接入带宽部分。
在步骤504中，第二终端接收该RMSI。
在步骤505中，第二终端根据该RMSI确定第二初始接入带宽部分。
该步骤505的相关内容可以参见前述步骤404，在此省略详细描述。
示例性地，图5所示方法可以用于确定初始下行接入带宽部分，或者，初始上行接入带宽部分。也即是，第一初始接入带宽部分和第二初始接入带宽部分均为初始下行接入带宽部分，或者，均为初始上行接入带宽部分。
需要说明的是，在图5所示方法中，第一规则为：根据第二配置信息确定第一初始接入带宽部分(参见步骤503)。第二规则为：如果RMSI中包括第一配置信息，则将第一配置信息所指示的初始接入带宽部分作为第二初始接入带宽部分；如果RMSI中不包括第一配置信息，则根据CORESET#0的配置信息，确定第二初始接入带宽部分(参见步骤404)，也即是，第一规则和第二规则完全不同。
在本公开实施例中，针对接入带宽能力较差的第一终端，单独设置第二配置信息，保证第一终端根据第二配置信息确定出的第一初始接入带宽部分不超过第一终端的接入带宽能力，有利于第一终端的正常工作。
图6是根据一示例性实施例示出的一种初始接入带宽部分的确定方法的流程图。该方法可以由前述接入网设备和终端共同执行，在图6所示实施例中，终端包括第一终端和第二终端，第一终端的接入带宽能力低于第二终端的接入带宽能力，参见图6，该方法包括以下步骤：
在步骤601中，接入网设备发送CORESET#0的配置信息和RMSI。
在一种可能的实施方式中，该RMSI包括用于指示第二终端的初始接入带宽部分的第一配置信息和用于指示第一终端的初始接入带宽部分的第二配置信息中的至少一种。在另一种可能的实施方式中，该RMSI既不包括第一配置信息，也不包括该第二配置信息。也就是说，接入网设备可以在RMSI中配置第一配置信息，也可以不配置第一配置信息；同样地，接入网设备可以在RMSI中配置第二配置信息，也可以不配置第二配置信息。
在步骤602中，第一终端接收RMSI。
在步骤603中，第一终端根据该RMSI确定第一初始接入带宽部分。
该步骤603可以包括：若RMSI中的第二配置信息未缺失(即RMSI包括第二配置信息)，则根据RMSI中的第二配置信息确定所述第一初始接入带宽；或者，若所述RMSI中的第二配置信息缺失(即RMSI不包括第二配置信息)，则根据CORESET#0的配置信息确定第一初始接入带宽部分。
这里，根据RMSI中的第二配置信息确定所述第一初始接入带宽的方式可以参见步骤503；根据CORESET#0的配置信息确定第一初始接入带宽部分的方式可以参见步骤402，在此省略详细描述。
在步骤604中，第二终端接收该RMSI。
在步骤605中，第二终端根据该RMSI确定第二初始接入带宽部分。
该步骤605的相关内容可以参见前述步骤404，在此省略详细描述。
可选地，图6所示方法可以用于确定初始下行接入带宽部分。也即是，第一初始接入带宽部分和第二初始接入带宽部分均为初始下行接入带宽部分。
需要说明的是，在图6所示方法中，第一规则为：根据第二配置信息确定第一初始接入带宽部分(参见步骤603)。第二规则为：如果RMSI中包括第一配置信息，则将第一配置信息所指示的初始接入带宽部分作为第二初始接入带宽部分；如果RMSI中不包括第一配置信息，则根据CORESET#0的配置信息，确定第二初始接入带宽部分，也即是，第一规则和第二规则完全不同。
在本公开实施例中，针对接入带宽能力较差的第一终端，单独设置第二配置信息，当RMSI中包括第二配置信息时，第一终端根据第二配置信息确定出的第一初始接入带宽部分不超过第一终端的接入带宽能力，而当RMSI中不包括第二配置信息时，第一终端根据CORESET#0的配置信息确定第一初始接入带宽部分，由于CORESET#0所在的频率资源较小，所以根据CORESET#0的配置信息确定出的第一初始带宽部分不会超过第一终端的接入带宽能力。因此，可以保证第一终端确定出的第一初始接入带宽部分不会超过第一终端的接入带宽能力，从而有利于第一终端的正常工作。
图7是根据一示例性实施例示出的一种初始接入带宽部分的确定方法的流程图。该方法可以由前述接入网设备和终端共同执行，在图7所示实施例中，终端包括第一终端和第二终端，第一终端的接入带宽能力低于第二终端的接入带宽能力，参见图7，该方法包括以下步骤：

在步骤702中，第一终端接收RMSI。
在步骤703中，第一终端根据第一配置信息确定第二初始接入带宽部分；
在步骤704中，第一终端根据第一终端的接入带宽能力，确定第二初始接入带宽的部分带宽为第一初始接入带宽部分。
示例性地，该步骤704可以包括：第一终端将第二初始接入带宽部分的起始频率位置作为第一初始接入带宽部分的起始位置，并将第一终端的接入带宽能力作为该起始频率位置的偏移量以确定第一初始接入带宽的结束位置。
在步骤705中，第二终端接收RMSI。
在步骤706中，第二终端根据该RMSI确定第二初始接入带宽部分。
可选地，图7所示方法可以用于确定初始下行接入带宽部分，或者，初始上行接入带宽部分。也即是，第一初始接入带宽部分和第二初始接入带宽部分均为初始下行接入带宽部分，或者，均为初始上行接入带宽部分。
当第二初始接入带宽部分为初始下行接入带宽时，该步骤706可以参见前述步骤404。
当第二初始接入带宽部分为初始上行接入带宽部分时，该步骤706可以包括：将RMSI中的第一配置信息所指示的初始接入带宽部分作为第二初始接入带宽部分。
需要说明的是，在图7所示方法中，第一规则为：根据第二配置信息确定第一初始接入带宽部分(参见步骤703和704)。第二规则参见步骤706，也即是，第一规则和第二规则完全不同。
在本公开实施例中，针对接入带宽能力较差的第一终端，通过根据所述第一终端的接入带宽能力，确定所述第二初始接入带宽的部分带宽为所述第一初始接入带宽部分，使得在第二初始接入带宽大于第一终端的接入带宽能力的情况下，第一终端确定出的第一初始接入带宽部分不会超过第一终端的接入带宽能力，有利于第一终端的正常工作。

在步骤803中，第一终端根据第一配置信息确定第二初始接入带宽部分。
在步骤804中，第一终端比较所述第二初始接入带宽部分和所述第一终端的接入带宽能力。
若所述第二初始接入带宽部分超过第一终端的接入带宽能力，则执行步骤805，若所述第二初始接入带宽部分不超过所述第一终端的接入带宽能力，则执行步骤806。
在步骤805中，第一终端根据CORESET#0的配置信息确定所述第一初始接入带宽部分。
该步骤805的相关内容可以参见前述步骤402。
在本公开的一些实施例中，该步骤805可以被替换为前述步骤503，或者，前述步骤603，或者，前述步骤703和704。

下面以分别对初始下行带宽部分(initial DL BWP)和初始上行带宽部分(initial UL BWP)的确定进行示例性说明。
一、initial DL BWP的确定
当RMSI所配置的initial DL BWP不大于第一终端的接入带宽能力时，第一终端按照RMSI中的配置设定initial DL BWP；
当RMSI所配置的initial DL BWP大于第一终端的接入带宽能力时，采用以下3种方式中的任一种确定initial DL BWP：
第一种、第一终端根据预定义规则1或2确定initial DL BWP
预定义规则1：将CORESET#0所占的频率大小和频率带宽设定为用户的initial DL BWP；
预定义规则2：以CORESET#0的起始频率位置为起点，根据第一终端的带 宽能力确定initial DL BWP的终点。
第二种、接入网设备在RMSI中为第一终端(也可以称为NR-lite)额外配置一个Initial DL BWP_extra(即第二配置信息)，第一终端将这个initial DL BWP_extra作为initial DL BWP。
第三种、第一种与第二种的结合。接入网设备可以在RMSI中额外配置Initial DL BWP_extra，但接入网设备也可以不配置Initial DL BWP_extra，当接入网设备不配置Initial DL BWP_extra时使用第一种方式确定initial DL BWP，当接入网设备配置Initial DL BWP_extra时，使用第二种方式确定initial DL BWP。
二、initial UL BWP的确定
当RMSI所配置的initial UL BWP不大于第一终端的接入带宽能力时，第一终端按照RMSI中的配置设定initial UL BWP。当RMSI所配置的initial UL BWP大于第一终端的接入带宽能力时，采用以下3种方式中的任一种确定initial UL BWP：

第二种、接入网设备在RMSI中为第一终端(也可以称为NR-lite)额外配置一个Initial UL BWP_extra(即第二配置信息)，第一终端将这个initial UL BWP_extra作为initial UL BWP。
第三种、第一种与第二种的结合。接入网设备可以在RMSI中额外配置Initial UL BWP_extra，但接入网设备也可以不配置Initial UL BWP_extra，当接入网设备不配置Initial UL BWP_extra时，使用第一种方式确定initial UL BWP；当接入网设备配置了Initial UL BWP_extra时，使用第二种方式确定initial UL BWP。
在本公开实施例中，针对接入带宽能力较差的第一终端，当第一配置信息所指示的初始接入带宽部分(即第二初始接入带宽部分)超过第一终端的初始接入带宽能力时，通过根据CORESET#0的配置信息确定第一初始接入带宽部分，或者，通过第二配置信息确定第一初始接入带宽部分，通过根据所述第一终端的接入带宽能力，确定所述第二初始接入带宽的部分带宽为所述第一初始接入带宽部分，使得在第二初始接入带宽大于第一终端的接入带宽能力的情况下，第一终端确定出的第一初始接入带宽部分始终不会超过第一终端的接入带宽能力，有利于第一终端的正常工作。
