Description

控制信道元CCE索引的确认方法及相关产品 技术领域
本申请涉及通信处理技术领域，尤其涉及一种控制信道元CCE索引的确认方法及相关产品。
背景技术
物联网(The Internet of Things，简称IOT)是指通过各种信息传感器、射频识别技术、全球定位系统、红外感应器、激光扫描器等各种装置与技术，实时采集任何需要监控、连接、互动的物体或过程，采集其声、光、热、电、力学、化学、生物、位置等各种需要的信息，通过各类可能的网络接入，实现物与物、物与人的泛在连接，实现对物品和过程的智能化感知、识别和管理。
在5G NR的物联网场景中，PDCCH(Physical Downlink Control Channel，物理下行控制信道)的覆盖可能会降低，有如下原因：物联网UE的接收天线数减少，导致PDCCH的接收天线分集增益降低；物联网UE的接收天线效率降低，如天线尺寸减小等，导致PDCCH的接收天线增益降低；物联网UE的带宽减小，导致PDCCH的频率分集增益降低h和PDCCH的聚合等级受限，因此，PDCCH需要覆盖恢复。

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的监听时机、搜索空间类型等性质。PDCCH的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)。
参阅图2，图2提供了一种CCE(Control Channel Element，控制信道元)索引的确认方法，该方法可以由用户设备执行，该方法如图2所示，包括如下步骤：
