技术领域
本申请涉及通信领域，具体涉及一种频域偏移的确定方法及装置、通信设备和可读存储介质。
背景技术
在FR2x,即Beyond52.6GHz频段，有可能会出现同步信号块(Synchronization Signal Block，SSB)的子载波间隔(Subcarrier Spacing,SCS)小于公共资源块(Common Resource Block，CRB)的SCS的情况，例如SSB SCS＝480k，CRB SCS＝960k。在实现本申请过程中，发明人发现现有技术中至少存在如下问题：如果按照现有协议(在FR2中定义k ssb用4个bits表示)方式去配置k ssb，其中，k ssb是指SSB资源最低频率到

的偏移量可能会有sync raster(同步栅格)或channel raster(信道栅格)不能使用，导致K ssb指示效果比较差。
发明内容
本申请实施例的目的是提供一种频域偏移的确定方法及装置、通信设备和可读存储介质，以解决现有技术中按照现有协议去配置K ssb，导致K ssb指示效果比较差的技术问题。
第一方面，本申请实施例提供了一种频域偏移的确定方法，包括：对同步信号块SSB进行检测；根据所述SSB中的第一指示域和/或第二指示域，确定所述SSB相对于公共资源块栅格的频域偏移值；其中，所述第一指示域为SSB频域偏移指示域，所述第二指示域为与所述第一指示域不同的至少一 个指示域的部分或者全部。
第二方面，本申请实施例提供了一种频域偏移的确定装置，包括：检测模块，用于对同步信号块SSB进行检测；确定模块，用于根据所述SSB中的第一指示域和/或第二指示域，确定所述SSB相对于公共资源块栅格的频域偏移值；其中，所述第一指示域为SSB频域偏移指示域，所述第二指示域为与所述第一指示域不同的至少一个指示域的部分或者全部。
第三方面，本申请实施例提供了一种通信设备，该通信设备包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的方法的步骤。

具体实施方式
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作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。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不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，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
首先对本申请相关术语进行解释：
1)初始搜索
用户设备(User Equipment，UE)在开机或者进行小区切换时需要用到初始搜索，其目的是获得小区的下行同步：1)时间同步检测；2)频率同步检测。
需要说明的是，初始搜索的一个最主要的功能是找到可以使用的网络，即UE根据其所支持的工作频段以及协议规定的同步信号快编号全局同步信道号(Global Synchronization Channel Number，GSCN)进行全网频段的盲搜。根据协议规定，在FR2频段(24.25G-100GHz)中，UE会以17.28MHz的步长(sync raster)进行盲检，以找到适合自己接入的频段用以接入。
2)SSB结构
初始搜索的过程由同步信号块(Synchronization Signal Block，SSB)完成。 SSB由主同步序列(Primary Synchronization Signal，PSS),辅同步序列(Secondary Synchronization Signal，SSS),PBCH(物理广播信道),解调参考信号(Demodulation Reference Signal，DMRS)在四个连续的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号内组成，主要用于下行同步，其结构如图1所示。
3)绝对坐标系
绝对坐标系是以Point A为参考点，用公共资源块(Common Resource Blocks，CRB)为“刻度”来表示的坐标体系；其中，Point A对应着CRB的载波0的中心点，其中，CRB在频域上由12个载波组成，从Point A开始从0往上编号。绝对坐标的作用之一就是通过Point A来找到可用资源(Bandwidth Part，BWP)位置。
4)K ssb指示
在成功解码SSS/PSS和物理广播信道(Physical Broadcast Channel，PBCH)以及SIB1后，可以通过已知的SSB位置(SSB的频域和时域资源数固定)来相对的获得Point A的位置，其主要包含的参数有：1)K ssb，即SSB资源最低频率到
Figure PCTCN2021089882-appb-000002
的偏移量；2)offsettopointA，即
Figure PCTCN2021089882-appb-000003
到Point A之间的Reference RB数量，如图2所示，图2是根据本申请实施例的Point A,offsetToPointA以及K ssb三者之间的关系示意图。
此外，根据标准协议描述，offsetToPointA的SCS是确定值，在FR1中是15k，在FR2中是60k。CRB的SCS是根据高层的subCarrierSpacingCommon配置的，FR1中可以是15k和30k；在FR2中是60k和120k。K ssb的SCS在FR1中是15k，在FR2中是根据高层subCarrierSpacingCommon配置的。与此同时，K ssb的值在FR2中是根据ssb-SubcarrierOffset指示的，总共4bits，即2 4＝16。因此可支持一个RB，即12个子载波的值。而在FR1中，K ssb低四位是ssb-SubcarrierOffset指示的，高一位由PBCH中除去MIB中的A+6位指示。
5)PBCH
由于SSB的内部结构是协议标准化的，因此，当UE在特定的同步频点搜到同步信号后，就可以尝试对SSB进行解码；其中，SSB里面包含的最重要的信息就是主信息块(Master Information Block,MIB)，其中，MIB包括以下信息：
systemFrameNumber IE：系统帧号；其中，完整的系统帧号需要10bit，而MIB的Payload中帧号只有高位6bit，低位的4bit在PBCH传输块中的非MIB比特中传送；
subCarrierSpacingCommon IE：初始接入流程中下行信号的子载波间隔，指示SIB1/OSI/初始接入的Msg2/Msg4/寻呼消息的子载波间隔；
ssb-SubcarrierOffset IE：SSB的最低子载波和与其最近的PRB之间的子载波间隔数；
dmrs-Type A-Position IE：PDSCH DMRS参考信号的配置；
pdcch-ConfigSIB1 IE：SIB1_PDCCH的配置，包括：控制资源集(Control Resource Set，CORESET)和搜索空间配置；
cellBarred IE：无线资源控制(Radio Resource Control，RRC)的接入控制参数，用于标识该小区是否被禁止；
intraFreqReselection IE：RRC接入控制参数，用于标识小区是否允许同频重选；
spare：保留bit位。
如图3所示，PBCH除了MIB信息还包括了一些其他信息：
A+1～A+4：增加的是4bit帧号信息，获得系统帧号的低位4bit后，结合前MIB中systemFrameNumber的6bit信息，就会得到整个10bit的帧号信息；
A+5：增加半帧信息bit，该bit指示是前半帧还是后半帧；
A+6～A+8：如果最大的SSB Index L＝64(即F>6GHz)，A+6～A+8标识SSB Index的高3位，否则，A+6：K ssb的高1位，A+7/A+8：保留bit。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的 频域偏移的确定方法和频域偏移的确定装置可以应用于无线通信系统中。该无线通信系统可以为新空口(New Radio，NR)系统，或者其他系统，例如：演进型长期演进(Evolved Long Term Evolution，eLTE)系统或者长期演进(Long Term Evolution，LTE)系统，或者后续演进通信系统等。进一步，可以应用于上述无线通信系统中的非授权频段(Unlicensed Band)。
请参见图4，图4是本申请实施例可应用的一种网络系统的结构图，如图4所示，包括终端11、中间设备12和网络设备13，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或者机器人等终端侧设备，需要说明的是，在本申请实施例中并不限定终端11的具体类型。中间设备12可以是大型智能表面(Large Intelligent Surfaces，LIS)等新型人造超材料的设备、反向散射设备(backscatter)、WiFi设备或者中继设备(例如：层一中继、放大转发中继或者透明转发中继等)等。上述网络设备13可以是网络设备、WiFi设备或者终端设备。其中，网络设备可以是4G基站，或者5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者传输接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备13可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。
本申请实施例中，终端11可以通过中间设备12与网络设备13进行通信，例如：中间设备12可以转发终端11向网络设备13发送的信号，也可以转发网络设备13向终端11发送的信号。其中，中间设备12的转发可以是直接转发、透明转发、放大转发或者对信号进行变频或者调制再发送等等，对此不作限定。当然，本申请实施例中，终端11与中间设备12之间传输的信号可以是用于在终端11和中间设备12之间需要传输的信号，即该场景可以不包括网络设备13。另外，终端11可以直接与网络设备13进行通信。
另外，本申请实施例中，LIS设备是一种新型的人造材料设备，LIS节点 可以动态地/半静态地调整自身的电磁特性，影响辐射到LIS节点的电磁波的反射/折射行为，例如改变反射/折射信号的频率、幅度、相位、极化方向、波束空间能量分布。LIS节点可以对电磁信号的反射波/折射信号进行操控，实现波束扫描/波束赋形等功能。
需要说明的是，本申请实施例提供的频域偏移的确定方法，执行主体可以为通信设备，该通信设备可以为上述终端或中间设备。本申请实施例中以终端执行加载频域偏移的确定方法为例，说明本申请实施例提供的频域偏移的确定方法。
请参见图5，图5是本申请实施例提供的一种频域偏移的确定方法的流程图，如图5所示，该方法的步骤包括：
步骤S502，对同步信号块SSB进行检测；
步骤S504，根据所述SSB中的第一指示域和/或第二指示域，确定所述SSB相对于公共资源块栅格的频域偏移值；
其中，所述第一指示域为SSB频域偏移指示域，所述第二指示域为与所述第一指示域不同的至少一个指示域的部分或者全部。
需要说明的是，在本申请实施例中以在第一频段上对SSB进行检测示例，而该第一频段在具体应用场景中可以是sync raster部分或全部，或其他可以传输同步信号块的频段。
在本申请的可选实施例中，本申请中涉及到的第二指示域可以为下情况中的至少一种：
情况1：所述第二指示域为公共SCS指示域的部分或全部。
可选地，对于上述情况1中的第二指示域为公共SCS指示域的部分或全部，的前提条件是：在公共子载波间隔SCS和第一SCS存在关联关系，其中，所述第一SCS为在所述第一频段检测到所述SSB的情况下确定的所述SSB的SCS。
基于上述情况1，本申请实施例中的频域偏移的确定方法，在具体应用场景中可以是：在>52.6GHz频段运行时，通过SSB的SCS可以得到CORESET#0 的SCS，即SSB的SCS和CORESET#0的SCS有绑定关系，例如支持(SSB,CORESET#0)＝(480K,960K),(960K,960K)，(1920K,1920K)，此时SSB的SCS为480K或者960K时，CORESET#0的SCS为960K；SSB的SCS为1920K时，CORESET#0的SCS为1920K。此时可以利用>52.6GHz频段中的subCarrierSpacingCommon指示域去指示K ssb最高位或最低位：当其指示最高位时，ssb-SubcarrierOffset指示K ssb低四位；当其指示最低位时，ssb-SubcarrierOffset指示K ssb高四位。
也就是说，若初始接入过程中的SCS是固定值，则可以将subCarrierSpacingCommon用作指示K ssb。需要说明的是，上述具体应用于场景>52.6GHz频段时，subCarrierSpacingCommon指示域为第二指示域，而ssb-SubcarrierOffset则是第一指示域。通过本申请实施例中的该方式，在不需要额外增加比特数量的情况下，可以利用现有未使用的指示域结合ssb-SubcarrierOffset指示K ssb，节省资源的同时又可以利用更多的比特去配置K ssb，从而可以更加灵活地进行K ssb配置。
情况2：所述第二指示域为物理下行共享信道解调参考信号位置指示域的部分或全部。
对于上述情况2中的所述第二指示域为物理下行共享信道解调参考信号位置指示域的部分或全部的前提条件是：在物理下行共享信道解调参考信号位置指示域和第一SCS存在关联关系的情况下，所述第二指示域为物理下行共享信道解调参考信号位置指示域的部分或全部；其中，所述第一SCS为在第一频段检测到所述SSB的情况下确定的所述SSB的SCS。
基于上述情况2，本申请实施例中的频域偏移的确定方法，在具体应用场景中可以是：在>52.6GHz频段运行时，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)-解调参考信号(Demodulation Reference Signal，DMRS)，即PDSCH-DMRS；其中，参考信号位置确定为2或3；或，参考信号的位置与SCS存在绑定关系，例如SCS480对应参考位置2；SCS960对应参考位置3，此时不需要DMRS-TypeA-Position去指示PDSCH DMRS的位 置，则此时可以利用>52.6GHz频段传输时SSB中的DMRS-TypeA-Position指示域去指示K ssb最高位或最低位：当其指示最高位时，ssb-SubcarrierOffset指示K ssb低四位；当其指示最低位时，ssb-SubcarrierOffset指示K ssb高四位。
也就是说，若PDSCH DMRS参考信号位置确定，则此时可以将dmrs-TypeA-Position用作指示K ssb。需要说明的是，上述具体应用场景中的>52.6GHz频段传输时SSB中的DMRS-TypeA-Position指示域为第二指示域，而ssb-SubcarrierOffset则是第一指示域。可见，通过本申请实施例中的该方式，在不需要额外增加比特数量的情况下，可以利用现有未使用的指示域结合ssb-SubcarrierOffset指示K ssb，节省资源的同时又可以利用更多的比特去配置K ssb，从而可以更加灵活地进行K ssb配置。
情况3：所述第二指示域为物理下行控制信道配置系统信息块指示域中的部分或全部。
基于上述情况3，本申请实施例中的频域偏移的确定方法，在具体应用场景中可以是：在>52.6GHz频段运行时，CORESET#0的配置表格进行修改，并且有效的entry数进行减少，例如只支持SSB和CORESET#0之间FDM的复用方式，或者支持SSB和CORESET#0的Multiplexing pattern 2/3，此时一个示例如表1所示，此时只需要2bit进行CORESET#0配置。而在FR1，FR2需要4bit进行指示，则此时可以利用>52.6GHz频段传输时SSB中的CORESET#0配置的高M比特位或者低M比特位(M>＝1)去指示K ssb高位或低位：当其指示高位时，ssb-SubcarrierOffset指示K ssb低四位；当其指示低位时，ssb-SubcarrierOffset指示K ssb高四位。
同理，Search space#0的配置表格也可以类似于CORESET#0用作K ssb指示。
Figure PCTCN2021089882-appb-000004
表1
也就是说，若SIB1_PDCCH的CORESET以及搜索空间不需要8bits的数据去指示，则空余的bit可以用来指示K ssb。需要说明的是，>52.6GHz频段传输时SSB中的CORESET#0配置的高M比特位或者低M比特位(M>＝1)为第二指示域，而ssb-SubcarrierOffset则是第一指示域。可见，通过本申请实施例中的该方式，在不需要额外增加比特数量的情况下，可以利用现有未使用的指示域结合ssb-SubcarrierOffset指示K ssb，节省资源的同时又可以利用更多的比特去配置K ssb，从而可以更加灵活地进行K ssb配置。
情况4：所述第二指示域为预留指示域的部分或全部。
其中，基于该第二指示域的可选项，本申请的实施例在具体应用场景中可以是：在>52.6GHz频段运行时，利用该频段SSB中的Spare bit进行K ssb最高位或最低位指示。当其指示最高位时，ssb-SubcarrierOffset指示K ssb低四位；当其指示最低位时，ssb-SubcarrierOffset指示K ssb高四位。
需要说明的是，>52.6GHz频段SSB中的Spare bit为第二指示域，而ssb-SubcarrierOffset则是第一指示域。可见，通过本申请实施例的该方式，在不需要额外增加比特数量的情况下，可以利用现有未使用的指示域结合ssb-SubcarrierOffset指示K ssb，节省资源的同时又可以利用更多的比特去配置K ssb，从而可以更加灵活地进行K ssb配置。
情况5：所述第二指示域为以下至少一个指示域的组合：公共SCS指示域、物理下行共享信道解调参考信号位置指示域(PDSCH-DMRS)、物理下行控制信道配置系统信息块指示域、预留指示域。
也就是说，可以利用上述情况1)至情况4)中各个指示域中的比特组合去指示K ssb高N位或低N位(N>1)。例如，公共SCS指示域中的一个比特 与PDSCH-DMRS指示域中的一个比特组合，公共SCS指示域中的一个比特与预留指示域中的两个比特组合等；其中，当其比特组合指示高N位时，ssb-SubcarrierOffset指示K ssb低四位；当其比特组合指示低N位时，ssb-SubcarrierOffset指示K ssb高四位。
可见，比起上述情况1)至情况4)中将单个指示域作为第二指示域的方式，在此情况5)中将多个指示域的组合作为第二指示域，可以利用更多的比特去指示K ssb，即指示K ssb的可能性更多。
可选地，本申请实施例中的频域偏移值包括：所述第一指示域的第一比特和所述第二指示域的第二比特联合指示的频域偏移值。其中，该第一比特的比特数量可以是一个或多个，且该第二比特的比特数量也可以是一个或多个。
进一步地，该所述第二指示域的第二比特，包括如下至少一项：所述第二指示域的空余比特、所述第二指示域的保留比特。对此，以上述情况1)至情况4)为例可知，该空余比特可以是以下指示域组合中的一个或多个比特组合：公共SCS指示域、物理下行共享信道解调参考信号位置指示域(PDSCH-DMRS)、物理下行控制信道配置系统信息块指示域；而该保留比特为预留指示域中的比特。
