图3是初始接入过程中终端设备接收SSB和SIB1的一个示意图。如图3所示，在初始接入过程中，终端设备102接收SSB和SIB1的操作包括：
操作301、在sync raster上检测接收SSB；
操作302、判断SSB的小区禁止(cellBar)域是否为禁止(barred)，如果是，不需根据该SSB接收SIB1(不管该SSB是否有关联的SIB1)，并进一步判断频率内重选择域(intraFrequencyReselection)是否为不允许(notallowed)，如果是，则无需在该SSB的频域位置检测接收其他SSB(即，UE认为不能基于该频域位置发送的SSB接入网络)，否则(即，intraFrequencyReselection为允许(allowed))，可以继续在该SSB的频域位置检测接收其他SSB；此外，在操作302中，如果判断cellBar域不为禁止(barred)，则进行到操作303；
操作303、判断该SSB是否关联有SIB1(或者说是否存在CORESET(CORESET#0)forType0-PDCCH CSS(即针对Type0-PDCCH CSS的CORESET，其中CSS是公共搜索空间，common search space)，或者，该小区是否广播SIB1)，如果是，则进行到操作304，否则检测接收其它SSB；

操作2、小区A向UE发送报告全局CID的请求(Report Global-CID Request)，从而请求UE发送Phy-CID＝5的小区B的Global-CID(即，小区A指示(instructs)UE读取小区B广播的NCGI(s)/ECGI(s),TAC(s),RANAC(s),PLMN ID(s)等(不一定都广播))；
操作2b、UE从小区B获得广播信道(BCCH)等(即，UE接收小区B的MIB和SIB1，以读取小区B广播的NCGI(s)/ECGI(s),TAC(s),RANAC(s),PLMN ID(s)等(包括在SIB1中)。特别地，UE可能根据小区B的SSB承载的MIB确定该小区没有广播SIB1)；
操作3、UE将小区B的Global-CID发送给小区A(特别地，小区B没有广播SIB1时，上报noSIB1)。
图5是ANR过程中终端设备接收SSB和SIB1的一个示意图，如图5所示，在ANR过程中，终端设备102接收SSB和SIB1的操作包括：
操作501、在基站指示的频域位置根据基站指示的物理小区标识检测接收SSB；
操作502、判断在操作301中接收的该SSB是否有关联的SIB1(或者说是否存在CORESET(CORESET#0)forType0-PDCCH CSS，或者，该小区是否广播SIB1)，如是，则进行到操作503，如否，则返回操作501；
操作503、确定CORESET for Type0-PDCCH CSS；
操作504、在Type0-PDCCH CSS监听并接收用于调度用于承载SIB1的PDSCH 的PDCCH；
操作505、接收PDCCH调度的用于承载SIB1的PDSCH，从而获取SIB1。
在本申请的各实施例中，采用某一子载波间隔(SCS)的SSB对应的同步光栅(sync raster)的频域位置(或者说，为某一SCS的SSB定义的sync raster的频域位置)，是指：终端设备(例如，UE)盲检(例如，在没有接收到指示SSB频域位置的信令的情况下检测接收)采用该SCS的SSB时基于的频域位置。
第一方面的实施例
第一方面的实施例提供一种收发信号的方法，应用于网络设备，例如，图1的网络设备101。
图6是本申请第一方面的实施例中收发信号的方法的一个示意图，如图6所示，该方法包括：
操作601、发送用于指示同步信号/PBCH块(SS/PBCH block,SSB)的频域位置的指示信息。
在操作601中，在SSB的子载波间隔为960kHz的情况下，该指示信息不指示具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)对应的频域位置，也就是说，指示信息指示的频域位置不同于(即，不能是，或者说不应是)预定GSCN value的sync raster对应的频域位置。
在第一方面的实施例中，SSB可以在FR2-2的频率范围内发送。此外，该具有预定GSCN value的同步光栅(sync raster)也可以在FR2-2的频率范围内。
在第一方面的实施例中，指示信息可以被包含在RRC信令中。例如，无线资源控制(RRC)信令指示SCS为960kHz的SSB的频域位置时，不指示预定GSCN value的sync raster对应的频域位置。
在至少一个实施例中，在没有为SCS为960kHz的SSB定义相应的同步光栅的情况下，具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)是指120kHz和/或480kHz的SSB定义的同步光栅(也就是说，用于盲检SCS为120kHz的SSB的同步光栅，和/或，用于盲检SCS为480kHz的SSB的同步光栅))，例如，当无线资源控制(RRC)信令指示SCS为960kHz的SSB的频域位置时，不能指示对应120kHz和/或480kHz的GSCN value的频域位置。由此，能够满足前向兼容性 的要求。
关于前向兼容性问题的考虑如下：
由于Rel-17中的采用960kHz的SSB不用于支持初始接入，其包括的MIB和/或关联的SIB1可能不包括用于支持初始接入的必要信息，例如SIB1中可能不包括servingCellConfigCommon等。这种情况下，这个SSB将不能用于初始接入。也就是说，即使UE能够在初始接入时接收到这个SSB，也无法基于这个SSB完成初始接入以接入网络。若在当前版本中(Rel-17)中，该SSB可以在任意频域位置发送，而后续版本(e.g.Rel-18)支持基于960kHz的SSB的初始接入(也就是说，后续版本中，UE会盲检SCS为960kHz的SSB)，可能会对后续版本UE的初始接入造成影响。例如，后续版本的UE可能在进行初始接入时接收到的SCS为960kHz的SSB但无法基于该SSB获取用于支持初始接入的必要信息，进而无法基于该SSB完成初始接入，从而增加了UE进行初始接入的时延和复杂度。通过限制当前版本中SCS为960kHz的SSB的频域位置，可以保留后续版本基于当前版本不能使用的频域位置盲检SCS为960kHz的SSB进行初始接入的可能性，避免当前版本的SCS为960kHz的SSB对后续版本可能造成的负面影响，保证了前向兼容性。
在一个具体实例中，RRC信令可以是MeasObjectNR，例如，一个MeasObjectNR中的ssbSubcarrierSpacing指示960kHz时，该MeasObjectNR中的ssbFrequency不能指示对应120kHz和/或480kHz的GSCN value的频域位置，例如下面的表3所示。
表3
Figure PCTCN2021110690-appb-000003
Figure PCTCN2021110690-appb-000004
在另一个具体实例中，RRC信令可以是ServingCellConfigCommon，例如，一个ServingCellConfigCommon中的ssbSubcarrierSpacing指示960kHz时，该ServingCellConfigCommon中的DownlinkConfigCommon中的(frequencyInfoDL中的)absoluteFrequencySSB不能指示对应120kHz和/或480kHz的GSCN value的频域位置。
在至少另一个实施例中，具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)是为SCS为960kHz的SSB定义的同步光栅。例如，在为SCS为960kHz的SSB定义了相应的synchronization raster的情况下，当RRC信令指示SCS为960kHz的SSB的频域位置时，不指示(例如，不能指示)对应960kHz的GSCN value的频域位置，并且，该SSB不在(例如，不能在)针对960kHz定义的sync raster上发送。
在第一方面的实施例中，如图6所示，该收发信号的方法还可以包括：
操作602、发送SSB，其中，在该SSB的子载波间隔为960kHz的情况下，该SSB的频域位置不同于具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)对应的频域位置。
在操作602中发送的SSB为被操作601中的指示信息指示了频域位置的SSB。
此外，操作602中发送SSB的网络设备/小区与操作601中发送指示信息的网络设备/小区可以相同，也可以不同。由此，网络设备在发送的SSB的SCS为960kHz的情况下，限制当前版本中SCS为960kHz的SSB的频域位置，使得该SSB的频域位置不同于预定GSCN value的sync raster对应的频域位置在终端设备侧，这样，终端设备可以保留后续版本基于当前版本不能使用的频域位置盲检SCS为960kHz的 SSB进行初始接入的可能性，避免当前版本的SCS为960kHz的SSB对后续版本可能造成的负面影响，也能够保证前向兼容性。
第二方面的实施例
至少针对与第一方面的实施例相同的问题，本申请第二方面的实施例提供一种收发信号的方法，应用于终端设备。第二方面的实施例的收发信号的方法与第一方面的实施例的收发信号的方法对应。
如图7所示，收发信号的方法包括：
操作701、接收用于指示同步信号/PBCH块(SS/PBCH block,SSB)的频域位置的指示信息。
在操作701中，在SSB的子载波间隔为960kHz的情况下，该指示信息不指示具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)对应的频域位置。
其中，该指示信息被包含在RRC信令中。
在至少一个实施例中，该具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)是为120kHz和/或480kHz的SSB定义的同步光栅。
在至少另一个实施例中，该具有预定全局同步信道号取值(GSCN value)的同步光栅(sync raster)是为SCS为960kHz的SSB定义的同步光栅。
在第二方面的实施例中，SSB在FR2-2的频率范围内接收。此外，同步光栅在FR2-2的频率范围内。
根据第二方面的实施例，接收指示SSB的频域位置的指示信息，能够便于在指示信息所指示的频域位置发送或接收SSB，并且，能够保证前向兼容性。
第三方面的实施例
第三方面的实施例提供一种收发信号的方法，应用于网络设备，例如图1的网络设备101。
图8是第三方面的实施例的收发信号的方法的一个示意图，如图8所示，该收发信号的方法包括：
操作801、发送同步信号/PBCH块(SSB)。
在操作801中，在SSB的子载波间隔是960kHz的情况下，该SSB的主信息块(MIB)中，小区选择相关的域被设定为第一预定值和/或小区重选相关的域被设定为第二预定值。
在至少一个实施例中，小区选择相关的域例如为小区禁止(cellbar)域，小区重选相关的域例如为同频小区重选(intraFreqReselection)域。其中，第一预定值为指示禁止(barred)的值，第二预定值为指示允许(allowed)的值。如表4所示。

在上述MIB包括的信息域中，cellBarred和intraFreqReselection用于指示小区选择和重选相关的信息。在现有技术中，当某一SCS的SSB不用于小区选择和重选，这两个信息域(field)将没有作用，这也意味着这两个信息域可能被设为任意值。而如果SCS为960kHz的SSB不可能用于小区选择和重选，如果按照现有技术，则这两个信息域也可能设为任意值。然而，这样也可能存在前向兼容性问题。
因此，考虑前向兼容性，可能需要限制SCS为960kHz的SSB中的上述两个信息域的取值。例如，针对SCS为960kHz的SSB，该SSB中的MIB的cellBarred必须指示barred，和/或，intraFreqReselection必须指示allowed。例如表4所示，针对SCS为960kHz的SSB，该SSB中的MIB的cellBarred必须指示barred，并且，intraFreqReselection必须指示allowed。其中，该SSB的频域位置可以是受限的(例如，如第一方面的实施例所述)，也可以是不受限的。也就是说，第一方面的实施例和第二方面的实施例可以结合在一个实施方式中，此外，第一方面的实施例和第二方面的实施例也可以在不同的实施方式被单独实施。
其中，cellBarred必须指示barred是解决在1中说明的前向兼容性问题的另一个方法。这样，后续版本的UE即使在进行初始接入时接收到上述SCS为960kHz但无法用于初始接入的SSB，由于其cellBarred必须指示barred，该UE也不会基于该SSB的指示进一步接收其关联的SIB1，从而一定程度上降低了对后续版本UE的初始接入 的影响。
而intraFreqReselection必须指示allowed是因为：在传统方法中，如果最高阶的小区(highest ranked cell)的MIB中cellBarred指示barred，而intraFreqReselection指示notAllowed，终端设备可能会认为网络不允许选择或重选intra-frequency cells，也就是说，对网络设备来说，在这个频域位置发送SSB的小区都是禁止接入的。如果当前版本的SCS为960kHz的SSB在任意频域位置发送且intraFreqReselection的值是任意的，当后续版本UE在初始接入时可能由于检测到当前版本的SCS为960kHz的SSB，因此，在第二方面的实施例中，使intraFreqReselection的值为第二预定值(allowed)。
在至少一个实施例中，该SSB在FR2-2的频率范围内发送。
在至少一个实施例中，该同步光栅在FR2-2的频率范围内。
图9是第三方面的实施例的收发信号的方法的另一个示意图，如图9所示，该收发信号的方法包括：
操作901、发送同步信号/PBCH块(SSB)，该SSB的MIB中包括用于指示与该SSB关联的SIB1的内容相关的信息；以及
操作902、发送与SSB关联的SIB1。
在操作901中，在SSB的SCS为960kHz的情况下，用于指示SSB关联的SIB1的内容相关的信息指示：该SIB1仅用于自动相邻关系报告或小区全局标识报告(ANR/CGI report)，或者，SIB1不包括用于支持初始接入的信息。由此，能够避免当前版本的SCS为960kHz的SSB对后续版本可能造成的负面影响，从而保证前向兼容性。
操作901中，SSB在FR2-2的频率范围内被接收。此外，在操作901中，同步光栅在FR2-2的频率范围内。
根据第三方面的实施例，能避免当前版本的SCS为960kHz的SSB对后续版本可能造成的负面影响，从而保证前向兼容性。
