具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请中术语“和/或”，仅仅是一种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。另外，本文中字符“/“，表示前后关联对象是一种“或”的关系。
本申请实施例中出现的“多个”是指两个或两个以上。本申请实施例中出现的第一、第二等描述，仅作示意与区分描述对象之用，没有次序之分，也不表示本申请实施例中对设备个数的特别限定，不能构成对本申请实施例的任何限制。本申请实施例中出现的“连接”是指直接连接或者间接连接等各种连接方式，以实现设备间的通信，本申请实施例对此不做任何限定。
本申请实施例的技术方案可以应用于如图1所示的示例通信系统100，该示例通信系统100包括终端110和网络设备120，终端110与网络设备120通信连接。
该示例通信系统100例如可以是：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE系统(LTE-based access to unlicensed spectrum，LTE-U)、免授权频谱上的NR系统(NR-based access tounlicensed spectrum，NR-U)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例中的终端110可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、中继设备、车载设备、可穿戴设备，未来5G网络中的终端或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端等，本申请 实施例对此并不限定。
本申请实施例中的网络设备120可以是用于与终端通信的设备，该网络设备可以是LTE系统中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继设备、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。
一般地，search space set(搜索空间集合)包含PDCCH监听时机、搜索空间类型等性质。PDCCH监听时机包括监听的时隙级别的周期和偏移量、时隙内的起始符号等；Search space set一般会绑定CORESET(Control Resource Set，控制资源集合)；CORESET包含PDCCH的频域资源和持续时间(符号数)等性质，一个PDCCH由一个或多个CCEs组成，一个PDCCH由n个CCEs组成，那么其聚合等级为n，一个CCE由6个REGs组成，一个REG等于一个OFDM符号内的一个资源块(Resource Block，RB)，一个CORESET中的REGs以时间优先的方式从小到大编号，编号0对应CORESET中第一个OFDM符号和最低编号的资源块。一个CORESET关联到一个CCE-to-REG映射，一个CORESET中的CCE-to-REG映射可以为交织或非交织，并且由REG bundles描述。
NR中的剩余最小系统信息相当于LTE中的SIB1，其包括除了MIB外的主要的系统信息。RMSI也可以称为SIB1。RMSI是在PDSCH里承载的，而 PDSCH是通过PDCCH调度的。承载RMSI的PDSCH一般被称为RMSI PDSCH，调度RMSI PDSCH的PDCCH一般被称为RMSI PDCCH。
RMSI PDCCH所在的search space set(搜索空间集合)一般被称为Type0-PDCCH search space set。一般地，Type0-PDCCH search space set可以由MIB配置，或者由RRC配置(切换等情形下)。Type0-PDCCH search space set可以被配置为search space 0(或search space set 0)。Type0-PDCCH search space set可以绑定CORESET 0。除了RMSI PDCCH的search space set，其他的公共搜索空间或公共搜索空间集合，如OSI PDCCH的search space set(Type0A-PDCCH search space set)、RAR PDCCH的search space set(Type1-PDCCH search space set)、paging PDCCH的search space set(Type2-PDCCH search space set)等，都可以配置为search space set 0。这些其他的公共搜索空间或公共搜索空间集合可以绑定CORESET0。一般地，上述公共搜索空间或公共搜索空间集合都可以被重新配置。
RMSI PDCCH监听时机与同步信号块有关联关系。UE根据RMSI PDCCH监听时机表格获得此关联关系。在初始接入过程中，UE搜索到某个同步信号块，UE根据PBCH指示的表格的行索引，确定该同步信号块关联的RMSI PDCCH的时域位置(起始符号索引或第一个符号索引)，就能够检测出RMSI PDCCH，并根据RMSI PDCCH调度来接收和解码RMSI PDSCH。
在NR中，一般地，UE是支持100MHz带宽的UE。UE在初始接入时，盲检同步信号块中的PSS/SSS/PBCH，获得PBCH内携带的MIB和时间索引信息。UE通过MIB中的信息获得调度SIB1的CORESET(可以称为CORESET0)及其search space set(可以称为search space set 0)的配置，进而，UE可以监听调度承载SIB1的PDSCH的Type0-PDCCH，并解码出SIB1。由于PBCH内通过表格来设置CORESET0的带宽，所以CORESET0的最大带宽在协议中被隐式地定义了。进一步来说，协议规定承载SIB1的PDSCH的频域资源在CORESET0的带宽(PRBs)内，因此承载SIB1的PDSCH的最大带宽在协议中也被隐式地定义了。实际上，在空闲态，UE工作在初始激活下行BWP(initial active DL BWP)内，该初始激活下行BWP的频域位置默认地与CORESET0的频域位置相同(非默认地，初始激活下行BWP的频域位置可以 通过信令修改为覆盖CORESET0的频域位置)。

步骤S201、获取高层参数；

需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模板并不一定是本申请所必须的。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
在本申请所提供的几个实施例中，应该理解到，所揭露的装置，可通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如上述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性或其它的形式。
上述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
上述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储器中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储器 中，包括若干指令用以使得一台计算机设备(可为个人计算机、服务器或者网络设备等)执行本申请各个实施例上述方法的全部或部分步骤。而前述的存储器包括：U盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成，该程序可以存储于一计算机可读存储器中，存储器可以包括：闪存盘、只读存储器(英文：Read-Only Memory，简称：ROM)、随机存取器(英文：Random Access Memory，简称：RAM)、磁盘或光盘等。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
