具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述之外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在NR系统中，网络设备可以在不同波束方向上发送一系列SSB(或称为SSB集合)，例如SSB1、SSB2、SSB3等。不同波束方向上的SSB(或称为不同索引的SSB)通常指示的type0 PDCCH的CORESET信息是相同的，CORESET信息用于指示type0 PDCCH在频域上的资源块RB和时域上的符号。不同波束方向上的SSB通常是时分发送的，相应的， 不同波束方向上的SSB对应的type0 PDCCH的监听时机可能不重叠、不完全重叠、或者完全重叠。
5G NR系统主要是为了支持eMBB业务而设计的，其主要技术是为了满足高速率、高频谱效率、大带宽的需要。实际上，除了eMBB，还存在多种不同的业务类型，例如传感器网络、视频监控、可穿戴等，它们在速率、带宽、功耗、成本等方面与eMBB业务有着不同的需求。支持这些业务的终端相比支持eMBB的终端的能力是降低的，如支持的带宽减小、处理时间放松、天线数减少等。为了更好的支持除eMBB业务之外的其他业务类型，需要针对这些业务和相应的低能力终端对NR系统进行优化，这样的系统称为NR-light系统。
在NR-light系统中，type0 PDCCH的CORESET的带宽比较有限，为了保证type0PDCCH的接收性能，通常采用时域上的重复发送，即在多个时间单元上发送type0 PDCCH。那么，对于每个索引的SSB对应的type0 PDCCH的监听时机可能都需要包含更多的时间单元。为了在带宽有限的CORESET承载每个索引的SSB对应的type0 PDCCH，就需要不同索引的SSB对应的type0 PDCCH监听时机尽量不重叠。为了满足上述要求，将会占用大量的下行子帧，造成接收SIB1的延迟。
基于上述存在的问题，本申请实施例提供一种控制信道资源的确定方法，对公共控制信道PDCCH的CORESET信息进行确定，通过SSB的PBCH承载的MIB信息，结合预定义的规则或者结合其他信息(比如索引信息、时间单元信息等)，确定不同索引的SSB对应的CORESET信息，确定的不同索引的SSB中存在至少两个SSB对应的CORESET信息不完全相同，从而使得UE在同一时间单元上的不同CORESET上检测type0 PDCCH，减小接收SIB1的延迟，使系统设计更加灵活。同时，针对任一SSB，type0 PDCCH的CORESET随着时间变化而变化，增加了CORESET的频率分集，提高了type0 PDCCH的接收性能。
本申请实施例的技术方案主要应用于基于NR技术的通信系统，例如第五代移动通信技术(5th generation mobile networks，简称5G)通信系统、NR-light系统等。也可以应用于其它的通信系统，只要该通信系统中存在实体需要指示与另一个实体通信时，另一个实体需要通过某种方式解读提前数据传输即可，例如可以应用在网络设备和终端设备之间进行多数据块的调度，或者两个终端设备，其中一个承担接入网络的功能等。具体的，该通信系统可以是例如：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、高级的长期演进LTE-A(LTE Advanced)系统、LTE频分双工(Freq终端设备ncy Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)等。
本申请实施例的技术方案中所称的终端设备可以是无线终端，也可以是有线终端。无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，简称RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，简称PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，简称SIP)话机、无线本地环路(Wireless Local Loop，简称WLL)站、个人数字助理(Personal Digital Assistant，简称PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile  Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。
本申请实施例的技术方案中所称的网络设备是一种部署在无线接入网用以提供无线通信功能的设备，可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是LTE中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，或者新空口NR网络中的收发点(transmission reception point,TRP)或者下一代节点B(generation nodeB，gNB)，或者未来其他的网络系统中的基站等等，在此并不限定。
本申请实施例的技术方案中的NR系统中，同步信号(Synchronization Signal，SS)与物理广播信道(Physical Broadcast Channel，PBCH)块是按照一定时频域资源关系以SS/PBCH资源块的形式出现，简称为同步信号块(Synchronization Signal Block,SSB)。SSB可以包括PBCH，主同步信号(primary synchronization signal，PSS)，辅同步信号(Secondary synchronization signal，SSS)中的至少一个。终端设备在接收到SSB后，可以取得与网络设备的时间同步，并且获取网络的基本配置信息，除此之外，终端设备还需要得到一些必要的系统信息才可以完成驻留小区及初始接入，这些必要的系统信息在NR中被称为RMSI(Remaining Minimum System Information)。RMSI可认为是LTE中的SIB1消息，主要通过物理下行共享信道(Physical Down Link Shared Channel，PDSCH)发送，而PDSCH信道需要物理下行控制信道(Physical Down Link Control Channel，PDCCH)的下行控制信息(Downlink Control Information，DCI)来调度。SSB承载信息的信道为PBCH，PBCH用于承载主信息块(main information block,MIB)。终端设备需要从MIB的pdcch-ConfigSIB1字段中得到调度RMSI的PDCCH信道信息，终端设备在该PDCCH上进行盲检，获得RMSI，即SIB1消息。
本申请实施例中的SSB与PDCCH具有准共址(Quasi Co-location,QCL)关系，可以表示两者具有相同的波束，或者具有相同的以下部分或者全部参数：入射角(angle of arrival,AOA)、主(Dominant)入射角AOA、平均入射角、入射角的功率角度谱(power angular spectrum(PAS)of AoA)、出射角(angle of departure,AoD)、主出射角、平均出射角、出射角的功率角度谱、终端发送波束成型、终端接收波束成型、空间信道相关性、基站发送波束成型、基站接收波束成型、平均信道增益、平均信道时延、时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移等。当SSB与PDCCH具有QCL关系时，也可称为两者具有关联关系，关联也可以称为映射，对应，相关，分配。上述关联关系可以由网络设备配置，也可以由标准规定，或者网络设备和终端设备预先约定。
图1为本申请实施例提供的一种通信系统的结构示意图。如图1所示，该系统包括网络设备，网络设备可以为基站(Base station，BS)，以及与网络设备通信连接的多个终端设备，例如图1所示的UE1至UE6。其中，基站可以是多波束的基站，也可以是单波束的基站。终端设备可以是固定的终端设备，也可以是移动的终端设备。基站和UE1至UE6组成一个通信系统，在该通信系统中，基站可以采用波束扫描方式发送一系列SSB，以使UE1至UE6中的一个或多个UE根据接收到的至少一个SSB确定至少一个SSB对应的CORESET信息，进行PDCCH的检测，接收SIB1。
下面结合附图以具体的几个实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程在某些实施例中不再赘述。
图2为本申请实施例提供的一种控制信息资源的确定方法的流程图。如图2所示，本实施例提供的方法可应用于图1所示的任意一个UE，该方法包括如下步骤：
步骤101、接收多个SSB，多个SSB中的每个SSB包含CORESET信息和SSB索引信息。
在本申请实施例中，多个SSB中的每个SSB包含CORESET信息，不同SSB包含的CORESET信息可以相同也可以不同。
示例性的，多个SSB包括SSB0、SSB1、SSB2，SSB0包含的CORESET信息为CORESET#0-0，SSB1包含的CORESET信息为CORESET#0-1，SSB2包含的CORESET信息为CORESET#0-2。其中，CORESET#0-0、CORESET#0-1、CORESET#0-2可以是完全相同的CORESET，也可以是不完全相同的CORESET。上述3个SSB的CORESET不完全相同可以理解为3个SSB中的至少2个SSB包含的CORESET不完全相同，还可以理解为3个SSB中的任意2个SSB包含的CORESET不完全相同。
对于每一个SSB，该SSB包含的CORESET信息可以承载在SSB的PBCH的MIB信息中。MIB信息中包含的CORESET信息可以是该SSB对应的CORESET信息(即MIB信息中指示的是该SSB真实的CORESET信息)，也可以是该SSB的一个参考CORESET信息(即并非该SSB真实的CORESET信息)。不同情况的CORESET信息对应的后续处理存在差异，具体可参见下文步骤102。
具体的，在SSB的PBCH承载的MIB信息的pdcch-ConfigSIB1字段中，指示了type0PDCCH的CORESET信息。其中，CORESET信息包括type0 PDCCH在频域上的资源块RB和在时域上的符号。在实际应用中，可通过在pdcch-ConfigSIB1字段中指示表1中的任一索引(index)，确定该索引对应的CORESET的RB个数(Number of RBs)、符号数(Number of Symbols)以及相比SSB的RB偏移值(RB offset)，从而得到上述CORESET信息。
表1
Figure PCTCN2020077255-appb-000001
需要说明的是，上述表1示出了子载波间隔为15kHz的情况，CORESET的带宽可以配置为24、48、96个RB，CORESET的符号个数可以为1、2、3，CORESET的频域位置相比SSB的频域位置偏移的RB个数可以为0、2、4、12、16、38。表1中的SSB与CORESET的复用方式为方式1，即PDCCH与SSB采用时分复用方式。当然，SSB与CORESET的复用方式还可以是方式2(PDCCH与SSB采用频分和时分复用方式)或方式3(PDCCH与SSB采用频分复用方式)。上述表1仅作为示例，对于不同子载波间隔或不同复用方式，对应的表格内容存在差异。
具体的，在SSB的PBCH承载的MIB信息的pdcch-ConfigSIB1字段中，还指示了type0PDCCH的搜索空间Searchspace信息，该信息用于确定type0 PDCCH的监听时机(即起始OFDM符号编号)。
type0 PDCCH的监听时机通过以下方式确定：
对于SSB与CORESET的复用方式为方式1，UE在两个连续的时隙监听type0 PDCCH公共搜索空间。两个连续的时隙中起始时隙的编号为n 0，每个索引的SSB对应一个监听窗口，该监听窗口的起始时隙的编号n 0可通过公式一确定：
Figure PCTCN2020077255-appb-000002
式中，i为SSB的索引号，μ为与子载波间隔Δf相关的系统参数，
Figure PCTCN2020077255-appb-000003
为一个无线帧中的时隙的个数，M和O均通过PBCH中的Searchspace信息指示。O的取值在6GHz以下频域(frequency range 1)时包括{0,2,5,7}，在6GHz以上频域(frequency range 2)时包括{0,2.5,5,7.5}。M的取值包括{1/2,1,2}。
在确定起始时隙的编号n 0之后，还需要进一步确定监听窗口所在的无线帧编号SFN C，可通过公式二或三确定：
Figure PCTCN2020077255-appb-000004
Figure PCTCN2020077255-appb-000005
即如果
Figure PCTCN2020077255-appb-000006
计算得到的时隙个数小于一个无线帧包含的时隙个数，SFN C为偶数无线帧，如果
Figure PCTCN2020077255-appb-000007
计算得到的时隙个数大于或等于一个无线帧包含的时隙个数，SFN C为奇数无线帧。
在本申请实施例中，SSB的PBCH承载的MIB信息的pdcch-ConfigSIB1字段包含8比特，type0 PDCCH的CORESET信息和Searchspace信息各占4比特。不同索引的SSB的PBCH承载的CORESET信息可以相同也可以不同，其中，不同索引的SSB的PBCH承载的CORESET信息不同即不同索引的SSB对应的MIB信息不同。
步骤102、根据SSB包含的CORESET信息和SSB索引信息，确定SSB的索引对应的CORESET信息。
其中，包含不同SSB索引信息的多个SSB对应的CORESET信息不完全相同。
在本申请实施例中，UE接收多个SSB，根据多个SSB确定多个SSB对应的CORESET信息。为了便于理解，下面以第一SSB为例进行说明，第一SSB为多个SSB中的任意一个SSB。其中，第一SSB包括以下两种情况：
在第一种情况下，第一SSB包含的CORESET信息为第一SSB对应的CORESET信息。需要指出的是，第一SSB包含的CORESET信息是指第一SSB的PBCH中指示的CORESET信息。该情况下，第一SSB包含的CORESET信息就是第一SSB对应的CORESET信息。不同索引的SSB包含的CORESET信息不完全相同，即不同索引的SSB对应的CORESET信息不完全相同。
作为一种示例，UE接收到多个SSB，例如SSB0、SSB1、SSB2、SSB3。SSB0包含的CORESET信息为SSB0对应的CORESET信息，SSB1包含的CORESET信息为SSB1对应的CORESET信息，SSB2包含的CORESET信息为SSB2对应的CORESET信息，SSB3包含的CORESET信息为SSB3对应的CORESET信息。上述4个索引的SSB包含的CORESET信息不完全相同，即指示的这4个索引的SSB对应的CORESET信息不完全相同。其中，CORESET信息不完全相同包括RB不完全相同(即RB可以部分重叠或者不重叠)。可选的，上述4个索引的SSB中存在至少两个SSB包含的CORESET信息不完全相同。
作为另一种示例，如图3所示，上述4个索引的SSB包含的CORESET信息不同，即指示的这4个索引的SSB对应的CORESET信息不同。其中，CORESET信息不同包括RB 不同(RB不重叠)，或者，RB不同且符号数不同。RB由RB个数和RB偏移值确定，RB不同包括RB个数不同，和/或，RB偏移值不同。图3示出的4个索引的SSB对应的CORESET信息，分别为CORESET#0-0、CORESET#0-1、CORESET#0-2、CORESET#0-3，它们具有相同的RB个数、符号数，只是RB偏移值不同。可选的，上述4个索引的SSB中存在至少两个SSB包含的CORESET信息不同，即指示的这4个索引的SSB中存在至少两个SSB对应的CORESET信息不同。
采用上述第一种情况确定多个SSB对应的CORESET信息，由于不同索引的SSB中存在至少两个SSB包含的CORESET信息不完全相同，即不同索引的SSB中存在至少两个SSB对应的CORESET信息不完全相同，那么即使不同索引的SSB对应的type0 PDCCH的监听时机发生了重叠，由于CORESET信息不完全相同，UE可以在同一时间单元的不完全相同的CORESET上接收对应的type0 PDCCH，从而避免占用大量的下行子帧，降低接收SIB1的延迟，使系统设计更加灵活。
在第二种情况下，第一SSB包含的CORESET信息并非第一SSB对应的CORESET信息，第一SSB包含的CORESET信息可以被看作是一个参考的CORESET信息。
具体的，可通过如下一种可能的实现方式确定第一SSB对应的CORESET信息：
根据第一SSB包含的CORESET信息和索引信息，确定第一SSB对应的CORESET信息。其中，索引信息用于指示CORESET与第一SSB的RB偏移值，可通过如下公式四确定RB偏移值。
RB offset i＝RB offset 0+i×NB          公式四
式中，RB offset i为第一SSB对应的CORESET信息中的RB偏移值，RB offset 0为第一SSB包含的CORESET信息中的RB偏移值，i为第一SSB的索引号，NB表示窄带narrow band的带宽。
其中，i的取值范围为[0,L-1]，L为SSB所在频段对应的SSB的最大个数。SSB的最大个数L与系统的频段有如下关系：频段(frequency range)小于或者等于3GHz，L取4；频段大于3GHz且小于6GHz，L取8；频段大于或者等于6GHz且小于52.6GHz，L取64。
其中，第一SSB的索引号可通过PBCH的解调参考信号(Demodulation Reference Signal，DMRS)或者PBCH承载的信息来指示。
通过公式四可确定第一SBB对应的CORESET信息，由公式四可知，第一SSB包含的CORESET信息与第一SSB对应的CORESET信息通常是不同的。
需要说明的是，上述的实现方式仅作为一种示例，还可根据其他预设规则确定第一SSB对应的CORESET信息，对此本申请实施例不作任何限制。
上述第二种情况下，不同索引的SSB包含的CORESET信息均为上述参考的CORESET信息，即不同索引的SSB包含的CORESET信息相同。不同索引的SSB对应的CORESET信息均可以通过上述的实现方式确定。
作为一种示例，UE接收到多个SSB，例如SSB0、SSB1、SSB2、SSB3。SSB0、SSB1、SSB2、SSB3包含的CORESET信息相同。UE根据SSB0包含的CORESET信息和SSB0的索引号，确定SSB0对应的CORESET信息，SSB0对应的CORESET信息为SSB0真实的CORESET信息。同理，UE根据SSB1包含的CORESET信息和SSB1的索引号，确定SSB1对应的CORESET信息；UE根据SSB2包含的CORESET信息和SSB2的索引号，确定SSB2对应的CORESET信息；UE根据SSB3包含的CORESET信息和SSB3的索引号，确定SSB3对应的CORESET信息。如此一来，上述4个索引的SSB对应的CORESET平移至不同的窄带上，如图4所示，上述4个索引的SSB对应的CORESET信息，具有相同的RB个数、符号数，只是RB偏移值不同。上述4个索引的SSB对应的CORESET分别为CORESET#0-0、CORESET#0-1、CORESET#0-2、CORESET#0-3，它们是基于相同的CORESET信息(即参考的CORESET信息)分别平移不同的RB偏移值(RB Offset 0、RB  Offset 1、RB Offset 2、RB Offset 3)得到的。上述4个索引的SSB对应的CORESET信息不同。
该示例中确定的4个索引的SSB对应的CORESET信息不同，与第一种情况的图3示例的结果一致，两者的区别在于：第一种情况不同索引的SSB包含的CORESET信息本身就不同，指示的不同索引的SSB对应的CORESET信息就不同；第二种情况不同索引的SSB包含的CORESET信息相同，需要通过其他信息(例如索引信息)确定不同索引的SSB对应的CORESET信息不同。
采用上述第二种情况确定多个SSB对应的CORESET信息，由于确定的不同索引的SSB对应的CORESET信息不同，那么即使不同索引的SSB对应的type0 PDCCH的监听时机发生了重叠，由于CORESET信息不同，UE可以在同一时间单元的不同CORESET上接收对应的type0 PDCCH，从而避免占用大量的下行子帧，降低接收SIB1的延迟，使系统设计更加灵活。另外，由于不同索引的SSB中的PBCH指示相同的CORESET信息，对相关技术改动小，便于不同索引的SSB的PBCH进行合并。
可选的，上述第一SSB对应的CORESET信息在不同时间单元中的至少两个时间单元不完全相同。
步骤103、根据多个SSB对应的CORESET信息检测PDCCH。
本申请实施例提供的控制信道资源的确定方法，UE接收多个SSB，其中多个SSB中的每个SSB包含CORESET信息和SSB索引信息，针对每一个SSB，UE根据SSB包含的CORESET信息和SSB索引信息确定SSB对应的CORESET信息。UE确定的包含不同索引信息的多个SSB对应的CORESET信息不完全相同，UE根据多个SSB对应的CORESET信息检测PDCCH。由于不同索引的SSB对应CORESET信息不完全相同，UE可以在同一时间单元的不完全相同的CORESET上接收不同索引SSB对应的PDCCH，提高了PDCCH的接收性能，降低了UE接收SIB1的延迟，使系统设计更加灵活。
图5为本申请实施例提供的一种控制信息资源的确定方法的流程图。如图5所示，本实施例提供的方法可应用于图1所示的任意一个UE，该方法包括如下步骤：
步骤201、接收第一SSB，第一SSB包含第一CORESET信息和第一SSB的索引信息。
相关技术中，第一SSB包含的第一CORESET信息通常为第一SSB对应的CORESET信息，即指示该SSB对应的真实的CORESET信息。本步骤中，第一SSB包含的第一CORESET信息为一个参考的CORESET信息，UE需要结合其他信息确定该SSB对应的真实的CORESET信息。
步骤202、根据第一CORESET信息和第一SSB的索引信息，确定第一SSB对应的第二CORESET信息；
步骤203、根据第一SSB对应的第二CORESET信息检测PDCCH。
本申请实施例中的步骤202同上述实施例中步骤102的第二种情况，其实现原理和技术效果可参见上述实施例，此处不再赘述。
相关技术中，第一SSB对应的CORESET信息通常是固定不变的，除非网络设备重新配置了新的第一SSB对应的CORESET信息。为了进一步提升type0 PDCCH的接收性能，下述实施例从多个SSB的任意一个SSB角度出发，确定低能力UE如何实现type0 PDCCH的CORESET的窄带跳频，通过窄带跳频，不仅可以实现SSB对应的CORESET信息在不同时间单元不完全相同，还可以实现在某一时间单元的不同索引的SSB对应的CORESET信息不完全相同。
下面结合附图6对本申请实施例提供的控制信道资源的确定方法进行详细描述。
图6为本申请实施例提供的一种控制信息资源的确定方法的流程图。如图6所示，本实施例提供的方法可应用于图1所示的任意一个UE，该方法包括如下步骤：
步骤301、确定第一SSB对应的第二CORESET信息。
在本申请实施例中，第一SSB包含的第一CORESET信息可以为第一SSB对应的第二CORESET信息。相应的，UE可根据第一SSB包含的第一CORESET信息确定第一SSB对应的第二CORESET信息。
或者，第一SSB包含的第一CORESET信息为一个参考的CORESET信息。相应的，UE可根据第一SSB包含的第一CORESET信息和第一SSB的索引信息确定第一SSB对应的第二CORESET信息。
步骤302、根据第二CORESET信息和时间单元信息，确定第一SSB对应的多个第三CORESET信息。
其中，多个第三CORESET信息分别对应不同的时间单元，多个第三CORESET信息不完全相同。
多个第三CORESET信息不完全相同可以理解为多个第三CORESET信息中的至少两个第三CORESET信息不完全相同，还可以理解为多个第三CORESET信息中的任意两个不完全相同。
作为一种示例，时间单元信息包括时间单元的编号，例如无线帧号、子帧号、时隙号等，时间单元的编号可以是一个或多个。
作为另一种示例，时间单元信息可以是UE监听type0 PDCCH的搜索空间的一个或多个监听时机。例如，第一SSB对应的CORESET属于UE监听type0 PDCCH的搜索空间的CORESET，该搜索空间包括不同的监听时机，该监听时机属于时间单元信息的一种，UE可以根据第一SSB对应的CORESET确定第一SSB对应的不同监听时机的多个CORESET。
本申请实施例中的时间单元可以是无线帧、子帧、时隙等，对此本申请实施例不作任何限制。
作为一种示例，步骤302包括：
通过如下公式五确定第一SSB对应的多个第三CORESET信息。
RB offset j＝RB offset 0+j×NB             公式五
式中，RB offset j为第一SSB对应的第三CORESET信息中的RB偏移值，RB offset 0为第一SSB对应的第二CORESET信息中的RB偏移值，j为第一时间单元的编号，NB表示窄带narrow band的带宽。
通过公式五可确定第一SSB对应的多个第三CORESET信息，由公式五可知，第一SSB对应的多个第三CORESET信息不完全相同。
需要说明的是，上述的实现方式仅作为一种示例，还可根据其他预设规则确定第一SSB对应的多个第三CORESET信息，对此本申请实施例不作任何限制。
综上，UE可以根据第一SSB包含的第一CORESET信息和时间单元信息确定第一SSB对应的多个第三CORESET信息，其中，第一SSB包含的第一CORESET信息为第一SSB对应的CORESET信息(即上述第二CORESET信息)。UE还可以根据第一SSB包含的第一CORESET信息、第一SSB的索引信息和时间单元信息，确定第一SSB对应的多个第三CORESEST信息。其中，上述的多个第三CORESET信息分别对应不同的时间单元，多个第三CORESET信息不完全相同。
作为一种示例，UE接收SSB0，SSB0包含的第一CORESET信息为SSB0对应的CORESET信息，UE根据SSB0包含的第一CORESET信息和无线帧SFN信息，确定多个第二CORESET信息，例如图7所示的第n个无线帧的第二CORESET信息(图7中的CORESET#0-0)，以及第n+i个无线帧的第二CORESET信息(图7中的CORESET#0-0’)。其中，n和i均为大于或者等于1的正整数。由图7可知，第n个无线帧和第n+i个无线帧的第二CORESET信息不同，此处的第二CORESET信息不 同是指RB个数和符号数相同，只是RB偏移值不同。
步骤303、根据多个第二CORESET信息检测PDCCH。
本申请实施例提供的控制信道资源的确定方法，UE接收第一SSB，其中第一SSB包含第一CORESET信息，UE根据第一CORESET信息确定第一SSB对应的第二CORESET信息，或者，UE根据第一CORESET信息和第一SSB的索引信息确定第一SSB对应的第二CORESET信息。随后，UE根据确定的第二CORESET信息和时间单元信息，确定第一SBB对应的多个第三CORESET信息，其中，多个第三CORESET信息对应不同的时间单元，确定的多个第三CORESET信息不完全相同。UE根据多个第三CORESET信息检测PDCCH。由于SSB对应的CORESET信息不再是固定不变的，SSB对应的CORESET信息随着时间的变化而变化，增加了检测type0 PDCCH的频率分集，提高了type0 PDCCH的接收性能。另外，从多个不同索引的SSB角度，可以使得同一时间单元的不同索引的SSB对应的CORESET不完全相同，UE在同一时间单元的不同CORESET上检测type0PDCCH，降低UE接收SIB1的延迟，使系统设计更加灵活。
图8为本申请实施例提供的一种控制信息资源的确定方法的流程图。如图8所示，本实施例提供的方法可应用于图1所示的基站，该方法包括如下步骤：
步骤401、确定多个SSB对应的CORESET信息。
其中，多个SSB中的每个SSB对应的CORESET信息是根据SSB包含的CORESET信息，或者，根据SSB包含的CORESET信息和SSB索引信息确定的。包含不同索引信息的多个SSB对应的CORESET信息不完全相同。
在本申请实施例中，基站以波束扫描方式向UE发送一系列SSB，例如SSB0、SSB1、SSB2、SSB3。相应的，UE可能接收到该基站发送的一系列SSB中的至少一个SSB，即UE可能接收到一个SSB，或者，UE接收到多个SSB(两个或两个以上)。
对于基站发送的一系列SSB中的任意一个SSB，例如第一SSB，该第一SSB包含的CORESET信息包括以下两种情况：
在第一种情况下，第一SSB包含的CORESET信息为第一SSB对应的CORESET信息，即第一SSB包含的CORESET信息直接指示了该第一SSB对应的CORESET信息。该情况下，基站直接根据第一SSB包含的CORESET信息确定第一SSB对应的CORESET信息。
在第二种情况下，第一SSB包含的CORESET信息并非第一SSB对应的CORESET信息，第一SSB包含的CORESET信息可以被看作是一个参考的CORESET信息。需要说明的是，在该情况下，不同索引的SSB包含的CORESET信息相同，基站可根据每个SSB包含的CORESET信息和该SSB的索引信息，确定该SSB对应的CORESET信息。示例性的，基站可根据第一SSB包含的CORESET信息和第一SSB的索引信息，确定第一SSB对应的CORESET信息。
步骤402、根据多个SSB对应的CORESET信息发送物理下行控制信道PDCCH。
具体的，基站根据步骤401确定的多个SSB对应的CORESET信息发送PDCCH。确定的不同索引的多个SSB对应的CORESET信息不完全相同。多个SSB对应的CORESET信息不完全相同可以理解为多个SSB中的至少两个SSB对应的CORESET信息不完全相同，还可以理解为多个SSB中的任意两个SSB对应的CORESET信息不完全相同。
其中，至少两个SSB对应的CORESET信息不完全相同包括至少两个SSB对应的RB不完全相同。
本申请实施例中的部分名词与UE侧的方法实施例相同，具体可参见上述实施例，此处不再赘述。
本申请实施例提供的控制信道资源的确定方法中，基站通过SSB包含的CORESET信息确定SSB对应的CORESET信息，或者通过SSB包含的CORESET信息和SSB索引信息确定SSB对应的CORESET信息。其中，基站确定的包含不同索引信息的多个SSB对 应的CORESET信息不完全相同。基站根据确定的多个SSB对应的CORESET信息发送PDCCH。上述方法减小了SIB1的发送延迟，使系统设计更加灵活。
在上述实施例的基础上，可选的，多个SSB中的任意一个SSB对应的CORESET信息在不同时间单元中的至少两个时间单元不完全相同。
图9为本申请实施例提供的一种控制信道资源的确定方法的流程图。如图9所示，本实施例提供的方法可应用于图1所示的基站，该方法包括如下步骤：
步骤501、根据第一SSB包含的第一CORESET信息和第一SSB的索引信息，确定第一SSB对应的第二CORESET信息。
在本申请实施例中，第一SSB包含的第一CORESET信息为一个参考的CORESET信息，基站需要根据该参考的CORESET信息和第一SSB的索引信息，确定第一SSB对应的第二CORESET信息。其中，第二CORESET信息为第一SSB对应的真实的CORESET信息。本步骤的具体实现方式可参见图2所示实施例中步骤102的第二种情况，此处不再赘述。
步骤502、根据第二CORESET信息发送PDCCH。
基站根据上述实施例的确定方法，确定第一SSB对应的第二CORESET信息，该第一SSB对应的第二CORESET信息可以随着时间的变化而变化，即该第一SSB对应的CORESET信息在不同时间单元可以不完全相同。
下面结合附图10对基站如何确定在不同时间单元的某一SSB对应的CORESET信息进行详细说明。
图10为本申请实施例提供的一种控制信道资源的确定方法的流程图。如图10所示，本实施例提供的方法可应用于图1所示的基站，该方法包括如下步骤：
步骤601、确定第一SSB对应的第二CORESET信息。
在一种可能的实现方式中，基站根据第一SSB包含的第一CORESET信息确定第一SSB对应的第二COERSET信息。
在另一种可能的实现方式中，基站根据第一SSB包含的第一CORESET信息确定第一SSB对应的第二CORESET信息。
步骤602、根据第二CORESET信息和时间单元信息，确定第一SSB对应的多个第三CORESET信息。其中，多个第三CORESET信息分别对应不同的时间单元，多个第三CORESET信息不完全相同。
本步骤的具体实现同图6所示实施例的步骤302，具体可参见上述实施例，此处不再赘述。
步骤603、根据多个第三CORESET信息发送PDCCH。
本申请实施例提供的控制信道资源的确定方法，基站首先根据第一SSB包含的第一CORESET信息，或者，根据第一SSB包含的第一CORESET信息和第一SSB的索引信息，确定第一SSB对应的第二CORESET信息。随后，基站根据确定第二CORESET信息和时间单元信息，确定第一SBB对应的多个第三CORESET信息，其中，确定的多个第三CORESET信息不完全相同。基站根据多个第三CORESET信息发送PDCCH。由于SSB对应的CORESET信息不再是固定不变的，SSB对应的CORESET信息随着时间的变化而变化，增加了发送type0 PDCCH的频率分集。另外，从多个不同索引的SSB角度，可以使得同一时间单元的不同索引的SSB对应的CORESET不完全相同，基站在同一时间单元的不同CORESET上发送type0 PDCCH，降低基站发送SIB1的延迟，使系统设计更加灵活。
