具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例进行说明之前，对相关内容进行简要说明。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在欧洲地区通信设备遵循“先听后说”(Listen-Before-Talk，LBT)原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进 行信号发送。且为了保证公平性，在一次传输中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。
目前在3GPP版本16(Rel-16)的NR-U技术用于7GHz以下的非授权频段，在后续的技术演进中，会考虑在更高的频段的非授权频谱的使用，以及相关的技术，如在Rel-17标准中讨论的52.6GHz-71GHz。
下面对新无线(New Radio，NR)系统中的同步信号(SS，synchronization signal)/物理广播信道(Physical Broadcast Channel，PBCH)块(block)进行说明。
NR系统中的公共信道和信号，如同步信号和广播信道，需要通过多波束扫描的方式覆盖整个小区，便于小区内的终端设备(User Equipment，UE)接收。SS的多波束发送可通过定义SS/PBCH簇集合(burst set)实现。一个SS burst set包含一个或多个SS/PBCH block，一个SS block用于承载一个波束的同步信号和广播信道。因此，一个SS burst set可以包含小区内SS block number个波束的同步信号。SS block number的最大数目L与系统的频段有关；具体的，在3GHz以下的频率范围，L的值为4；在3GHz到6GHz的频率范围，L的值为8；在6GHz到52.6GHz的频率范围，L的值为64。
一个SS/PBCH block(以下简称SSB)中包含一个符号的主同步信号(Primary Synchronization Signal，PSS)，一个符号的辅同步信号(Secondary Synchronization Signal，SSS)和两个符号的PBCH，如图1所示。其中，PBCH所占的时频资源中包含解调参考信号(demodulation reference signal，DMRS)，用于PBCH的解调。
SS/PBCH burst set内所有的SS/PBCH block在5ms的时间窗内发送，并以一定的周期重复发送，周期通过高层的参数SSB-timing进行配置，包括5ms，10ms，20ms，40ms，80ms，160ms等。对于终端设备来说，通过接收到的SS/PBCH block得到该SSB的索引(index)，SSB index对应该SSB在5ms时间窗内的相对位置，)根据该信息和PBCH中承载的半帧指示，或者帧同步。其中，SS/PBCH block的index通过PBCH的DMRS或者PBCH承载的信息来指示。在授权频谱中，例如，6GHz以下的频段，SSB burst中包含的SSB最多有8个，SSB index的取值为0-7。在使用授权频谱的NR系统中，SSB index可以用于获得帧同步和准共址(Quasi Co-Located，QCL)关系；对于前者，通过SSB index和半帧指示获得SSB在无线帧中的位置，从而获得帧同步。
对于SSB的频域位置，标准定义了用于初始接入的SSB所在的同步栅格的频域位置。对于授权频谱，同步栅格之间的间隔为1.2MHz或1.44MHz，分别对应0-3GHz和3-24.25GHz频率范围，如下表1所示。
表1.全局频率栅格的GSCN参数
Figure PCTCN2020105893-appb-000001
对于24.25GHz-100GHz的频段范围内的同步栅格的位置，同步栅格之间的间隔为17.28MHz，如下表所示。
表2.全局频率栅格的GSCN参数
Figure PCTCN2020105893-appb-000002
同步栅格之间间隔较小的原因是由于授权频段支持不同的信道带宽和频段分配，需要允许在尽可能多的频域位置上发送同步信号块以部署小区。对于非授权频谱，由于6GHz-7GHz频率范围的非授权频谱的信道带宽为20MHz，并且是多个运营商共享使用，因此信道带宽20MHz中不需要定义很多同步栅格的位置，通过减少同步栅格的位置可以减少UE的盲检测复杂度。在Rel-16的标准中定义每个20MHz只有一个允许的同步栅格。
PBCH信道承载的信息包括主信息块(Master information block，MIB)信息和物理层信息中8比特信息。物理层系统帧号(System Frame Number，SFN)、半帧指示、SSB索引等。PBCH承载的MIB信息包括6比特的SFN信息域，1比特的子载波间隔信息域，4比特的SSB的子载波偏移(ssb-SubcarrierOffset)信息域和8比特的pdcch-ConfigSIB1信息域等。其中，8比特的pdcch-ConfigSIB1信息域用于指示承载SIB1的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的调度信息的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的搜索空间信息。
针对SIB1的接收，在初始接入过程中，终端设备都是在主小区接收SIB1。在NR-U系统中，还有一种SIB1接收的情况是在辅小区接收SIB1。这是为了在NR-U系统中支持自动邻区关联(automatic neighbour relations，ANR)功能，以解决解决不同运营商部署小区时可能产生物理小区ID(PCI)冲突的问题。由于ANR功能依赖于SIB1的获取，需要在辅小区支持SIB1的接收。终端设备在接收到辅小区的SIB1之后，可以上报小区全球标识(Cell Global Identity，CGI)，用于网络的ANR功能。为了在辅小区接收SIB1，终端设备需要接收辅小区上配置的SS/PBCH block来获得Type0-PDCCH的搜索空间信息。由于辅小区并非用于初始接入的小区，用于携带Type0-PDCCH的搜索空间信息的SS/PBCH block的频域位置也并非位于同步栅格上，而是通过测量配置信息配置的SSB的频域位置的绝对无线频道编号(Absolute Radio Frequency Channel Number，ARFCN)，这样的SSB称为ANR SSB。在这种情况下，需要设计如何通过非同步栅格上接收到的SS/PBCH block来获得Type0-PDCCH的搜索空间信息。通过辅小区接收SIB1的示意图，如图2所示，包括以下步骤：
步骤1，检测ANR SS/PBCH block，解码PBCH获得MIB信息。
步骤2，通过MIB信息获得子载波偏移信息ssb-SubcarrierOffset得到

步骤3，根据k SSB确定common RB(CRB)的边界。
步骤4，根据MIB中的CORESET#0信息确定第一RB偏移。
步骤5，根据ANR SS/PBCH block的中心频率和该信道带宽内定义的允许的同步栅格的GSCN之间的频率偏移，确定第二RB偏移。

本申请实施例提供的控制信息的传输方法的一种可选处理流程，如图4所示，包括以下步骤：
步骤S201，终端设备从信道带宽内允许的至少两个同步栅格中确定一个第一同步栅格。
在一些实施例中，在信道带宽内允许的同步栅格的数量大于或等于两个的情况下，需从多个同步栅格中确定一个第一同步栅格；所述第一同步栅格用于确定控制资源集合的信息。
在一些实施例中，终端设备可以根据预设的规则从信道带宽内允许的至少两个同步栅格中确定一个第一同步栅格，即第一同步栅格为预定义的；在具体实施时，可以是协议约定的，也可以是终端设备与网络设备协商约定的。在另一些实施例中，终端设备可以根据终端设备检测到的SSB中的指示信息确定一个第一同步栅格。下面针对这两种确定第一同步栅格的方式分别进行说明。
方式1、在第一同步栅格为预定义的情况下，所述第一同步栅格为所述信道带宽内允许的同步栅格中频率最高的同步栅格；或者，所述第一同步栅格为所述信道带宽内允许的同步栅格中频率最低的同步栅格；或者，所述信道带宽内允许的同步栅格为N个，N为奇数，所述第一同步栅格为按频率大小顺序排列的N个同步栅格中第(N+1)/2个同步栅格；或者，所述信道带宽内允许的同步栅格为N个，N为偶数，所述第一同步栅格为按频率大小顺序排列的N个同步栅格中第N/2个同步栅格；或者，所述信道带宽内允许的同步栅格为N个，N为偶数，所述第一同步栅格为按频率大小顺序排列的N个同步栅格中第N/2+1个同步栅格；或者，所述第一同步栅格为与所述终端设备检测到的SSB的频率位置满足第一关系的同步栅格；或者，所述第一同步栅格由所述终端设备检测到的SSB中携带的PCI确定。
针对所述第一同步栅格为所述信道带宽内允许的同步栅格中频率最高的同步栅格的情况举例说明：若信道带宽内允许的同步栅格的数量为N，N个同步栅格对应的频率关系为f 1﹤f 2﹤f 3﹤…﹤f N，则频率f N对应的同步栅格为第一同步栅格。
针对所述第一同步栅格为所述信道带宽内允许的同步栅格中频率最低的同步栅格的情况举例说明：若信道带宽内允许的同步栅格的数量为N，N个同步栅格对应的频率关系为f 1﹤f 2﹤f 3﹤…﹤f N，则频率f 1对应的同步栅格为第一同步栅格。
针对所述信道带宽内允许的同步栅格为N个，N为奇数，所述第一同步栅格为按频率大小顺序排列的N个同步栅格中第(N+1)/2个同步栅格的情况举例说明：若信道带宽内允许的同步栅格的数量为7，将7个同步栅格对应的频率由大到小或者由小到大的顺序排列，则确定第3个同步栅格为第一同步栅格。
针对所述信道带宽内允许的同步栅格为N个，N为偶数，所述第一同步栅格为按频率大小顺序排列的N个同步栅格中第N/2个同步栅格的情况举例说明：若信道带宽内允许的同步栅格的数量为8，将8个同步栅格对应的频率由大到小或者由小到大的顺序排列，则确定第4个同步栅格为第一同步栅格。
针对所述信道带宽内允许的同步栅格为N个，N为偶数，所述第一同步栅格为按频率大小顺序排列的N个同步栅格中第N/2+1个同步栅格的情况举例说明：若信道带宽内 允许的同步栅格的数量为8，将8个同步栅格对应的频率由大到小或者由小到大的顺序排列，则确定第5个同步栅格为第一同步栅格。
针对所述第一同步栅格为与所述终端设备检测到的SSB的频率位置满足第一关系的同步栅格的情况举例说明：在一些实施例中，所述第一关系可以是与所述SSB的频率位置距离最近，或者与所述SSB的频率位置距离最远；因此，所述第一同步栅格可以是与所述终端设备检测到的SSB的频率位置距离最近的频率对应的同步栅格；或者，所述第一同步栅格可以是与所述终端设备检测到的SSB的频率位置距离最远的频率对应的同步栅格。
针对所述第一同步栅格由所述终端设备检测到的SSB中携带的PCI确定的情况举例说明：在一些实施例中，所述第一同步栅格为与所述终端设备检测到的SSB中携带的PCI具有对应关系的同步栅格。在具体实施时，所述PCI与所述第一同步栅格具有对应关系，可以是基于所述信道带宽内允许的同步栅格的数目对所述PCI执行取模运算得到的取模运算结果，与所述第一同步栅格的编号具有对应关系。若所述信道带宽内允许的同步栅格的数目为5，则对PCI执行模5运算得到的结果为0、或1、或2、或3、或4。所述信道带宽内允许的5个同步栅格可以按照同步栅格的频率位置由高到低的顺序、或者按照同步栅格的频率位置由低到高的顺序预先编号，如5个同步栅格的编号分别为0、1、2、3和4；当然，也可以对同步栅格以其他可实施的方式进行编号，如编号为A、B、C…等。以5个同步栅格的编号分别为0、1、2、3和4为例，若对PCI执行模5运算得到的结果为1，则终端设备确定第一同步栅格为编号为1的同步栅格。
方式2，终端设备可以根据终端设备检测到的SSB中的指示信息确定一个第一同步栅格。在一些实施例中，所述指示信息可以用于指示所述第一同步栅格的频率位置。
其中，所述指示信息的指示方式在本申请实施例中不做具体限定。如，所述SSB承载于PBCH上，则可以利用PBCH DMRS序列指示所述第一同步栅格的频率位置，也可以利用PBCH中承载的信息域中的比特信息指示所述第一同步栅格的频率位置。
步骤S202，基于所述第一同步栅格确定控制资源集合的信息。
在一些实施例中，终端设备确定检测到的SSB对应的频率与所述第一同步栅格对应的频率之间的第二资源块偏移，根据检测到的SSB中的MIB信息确定第一资源块偏移；根据第一资源块偏移和第二资源块偏移，确定控制资源集合的频域位置。在具体实施时，终端设备可以根据第一资源块偏移、第二资源块偏移、Type0-PDCCH的搜索空间信息来确定控制资源集合的信息。
在一些实施例中，终端设备确定检测到的SSB对应的频率与所述第一同步栅格对应的频率之间的第二资源块偏移时，可以根据SSB对应的中心频率与所述第一同步栅格对应的中心频率确定第二资源块偏移；也可以根据SSB对应的边缘频率与所述第一同步栅格对应的边缘频率确定第二资源块偏移；还可以根据所述SSB的某一个RB的common RB确定，如根据SSB的第一个RB对应的common RB之间的距离确定第二资源块偏移。
本申请实施例提供的控制信息的传输方法的另一种可选处理流程，如图5所示，包括以下步骤：
步骤S301，网络设备发送SSB，所述SSB用于终端设备从信道带宽内允许的至少两个同步栅格中确定一个第一同步栅格。
在一些实施例中，所述网络设备向终端设备发送SSB，所述SSB用于所述终端设备从信道带宽内允许的多个同步栅格中确定一个第一同步栅格，所述第一同步栅格用于确定控制资源集合的频域位置。
在一些实施例中，所述SSB包括指示信息，所述指示信息用于指示所述第一同步栅格的频率位置。在另一些实施例中，所述SSB中携带的PCI用于确定所述第一同步栅 格。
针对所述SSB中携带的PCI用于确定所述第一同步栅格的场景，所述PCI与所述第一同步栅格具有对应关系。其中，所述PCI与所述第一同步栅格的对应关系可以包括：基于所述信道带宽内允许的同步栅格的数目对所述PCI执行取模运算得到的取模运算结果，与所述第一同步栅格的编号具有对应关系。
在具体实施时，所述第一同步栅格的编号是基于所述信道带宽内允许的同步栅格的频率位置由高到低的顺序标识得到；或者，所述第一同步栅格的编号是基于所述信道带宽内允许的同步栅格的频率位置由低到高的顺序标识得到。
举例来说，若所述信道带宽内允许的同步栅格的数目为5，则对PCI执行模5运算得到的结果为0、或1、或2、或3、或4。所述信道带宽内允许的5个同步栅格可以按照同步栅格的频率位置由高到低的顺序、或者按照同步栅格的频率位置由低到高的顺序预先编号，如5个同步栅格的编号分别为0、1、2、3和4；当然，也可以对同步栅格以其他可实施的方式进行编号，如编号为A、B、C…等。以5个同步栅格的编号分别为0、1、2、3和4为例，若对PCI执行模5运算得到的结果为1，则终端设备确定第一同步栅格为编号为1的同步栅格。
下面基于不同的确定第一同步栅格的方式，对本申请实施例提供的控制信息的传输方法的具体实现过程进行详细描述。
通过预定义的方式确定第一同步栅格的情况下，本申请实施例提供的一种控制信息的传输方法的详细处理流程，如图6所示，包括以下步骤：
步骤S401，网络设备向终端设备发送ANR SS/PBCH block。
步骤S402，终端设备解码PBCH获得MIB信息，通过MIB信息获得子载波偏移信息。
步骤S403，终端设备根据子载波偏移信息确定CRB的边界。
步骤S404，终端设备根据MIB信息中的公共控制资源集合的信息确定第一资源块偏移。
步骤S405，终端设备根据预定义的规则从信道带宽内允许的多个同步栅格中确定一个第一同步栅格。
以预定义的规则为信道带宽内距离所述终端设备检测到的SSB的频率位置最近的频率对应的同步栅格为第一同步栅格为例，如图7所示，信道带宽内预定义的GSCN包括：GSCN0、GSCN1和GSCN2，SSB的ARFCN距离GSCN1最近，则确定GSCN1对应的栅格为第一同步栅格。
以预定义的规则为第一同步栅格由所述终端设备检测到的SSB中携带的PCI确定为例，终端设备接收并解调SSB之后得到PCI，根据预先定义的PCI与第一同步栅格的对应关系确定第一同步栅格。若信道带宽内允许的同步栅格的数量为3，则对PCI执行取模运算，得到的结果为0，信道带宽内允许的3个同步栅格的编号分别与0、1和2对应；则确定编号与0对应的同步栅格为第一同步栅格。这里，不同的PCI可能对应不同的第一
步骤S406，终端设备根据检测到的SSB对应的频率与所述第一同步栅格对应的频率确定第二资源块偏移。
在一些实施例中，以图7为例，终端设备根据GSCN1与SS/PBCH block所在的ARFCN之间的频率偏移确定第二资源块偏移。
步骤S407，终端设备根据第一资源块偏移和第二资源块偏移确定控制资源集合的频率位置。
需要说明的是，本申请实施例中，步骤S401至步骤S404，以及步骤S406至步骤 S407的可基于现有技术实现，这里不再赘述。
本申请实施例中，通过预先定义第一同步栅格，能够节省网络设备向终端设备指示第一同步栅格带来的信令开销。
通过SSB中的指示信息确定一个第一同步栅格的情况下，本申请实施例提供的另一种控制信息的传输方法的详细处理流程，如图8所示，包括以下步骤：
步骤S501，网络设备向终端设备发送ANR SS/PBCH block，终端设备解码PBCH获得MIB信息。
步骤S502，终端设备通过MIB信息获得子载波偏移信息。
步骤S503，终端设备根据子载波偏移信息确定CRB的边界。
步骤S504，终端设备根据MIB信息中的公共控制资源集合的信息确定第一资源块偏移。
步骤S505，终端设备根据SSB中的指示信息从信道带宽内允许的多个同步栅格中确定一个第一同步栅格。
在一些实施例中，SSB中包括指示信息，所述指示信息用于指示第一同步栅格的频率位置。
在一些实施例中，所述指示信息的指示方式在本申请实施例中不做具体限定。如，所述SSB承载于PBCH上，则可以利用PBCH DMRS序列指示所述第一同步栅格的频率位置，也可以利用PBCH中承载的信息域中的比特信息指示所述第一同步栅格的频率位置。
举例来说，PBCH承载的信息包括来自高层的A比特信息和物理层相关的额外8比特信息，其中，物理层相关的信息包括SFN、半帧指示、SSB index等。具体定义可以如下：
PBCH承载的比特包括来自高层的MIB信息，共A比特，
Figure PCTCN2020105893-appb-000008
以及来自物理层相关的8比特，
Figure PCTCN2020105893-appb-000009
其中A比特MIB信息的定义如下标准所描述，即包括6比特的SFN，1比特的子载波间隔信息，4比特的SSB的子载波偏移，DMRS相关信息、调度SIB的PDCCH的资源信息等，还包含1个空闲比特。其中，物理层相关的8比特，
Figure PCTCN2020105893-appb-000010
中，
Figure PCTCN2020105893-appb-000011
为SFN的最低4位，
Figure PCTCN2020105893-appb-000012
为半帧指示。当L SSB＝64时，
Figure PCTCN2020105893-appb-000013
为SSB index的最高3位，否则，
Figure PCTCN2020105893-appb-000014
为参数k SSB的最高位，
Figure PCTCN2020105893-appb-000015
为保留比特。其中，L SSB为最大的SSB个数，k SSB为SSB的子载波偏移信息。当系统频带小于6GHz时，即L SSB小于64时，层1相关的信息有2比特保留比特。
在一些实施例中，SSB不是用于终端设备的初始接入，其中，PBCH承载的信息可以用来表示其他的含义，例如多个允许的同步栅格的其中一个同步栅格的位置。举例来说，信道带宽内预定义了5个同步栅格，通过SSB的指示信息指示其中一个同步栅格的位置，用于计算第二资源块偏移。在PBCH中的具体指示方法在这里不做限定，例如利用PBCH DMRS序列，利用PBCH中承载的上述信息域中的比特等。
如图9所示，信道带宽内预定义的GSCN包括：GSCN0、GSCN1和GSCN2，SSB的指示信息指示第一同步栅格的频率位置对应GSCN0。
步骤S506，终端设备根据检测到的SSB对应的频率与所述第一同步栅格对应的频率确定第二资源块偏移。
在一些实施例中，以图8为例，终端设备根据GSCN0与SS/PBCH block所在的ARFCN之间的频率偏移确定第二资源块偏移。
步骤S507，终端设备根据第一资源块偏移和第二资源块偏移确定控制资源集合的频率位置。
需要说明的是，本申请实施例中，步骤S501至步骤S504，以及步骤S506至步骤S507的可基于现有技术实现，这里不再赘述。
本申请实施例中，网络设备可以通过SSB灵活的指示第一同步栅格的位置，使得终端设备可以根据SSB的指示从信道带宽内允许的多个同步栅格中确定第一同步栅格，实现了控制资源集合的灵活配置。
需要说明的是，本申请实施例中所述的SSB可以是ANR SSB。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
