具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
图1A示出了本申请涉及的无线通信系统。所述无线通信系统不限于长期演进(Long Term Evolution，LTE)系统，还可以是未来演进的第五代移动通信(the 5th Generation，5G)系统、NR系统，机器与机器通信(Machine to Machine，M2M)系统等。如图1A所示，无线通信系统100可包括：一个或多个网络设备101和一个或多个用户设备102。其中：
网络设备101可以为基站，基站可以用于与一个或多个用户设备进行通信，也可以用于与一个或多个具有部分用户设备功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)。基站可以是时分同步码分多址(Time Division Synchronous Code Division Multiple Access，TD-SCDMA)系统中的基站收发台(Base Transceiver Station，BTS)，也可以是LTE系统中的演进型基站(Evolutional Node B，eNB)，以及5G系统、新空口(NR)系统中的基站。另外，基站也可以为接入点(Access Point，AP)、传输节点(Trans TRP)、中心单元(Central Unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。
用户设备102可以分布在整个无线通信系统100中，可以是静止的，也可以是移动的。 在本申请的一些实施例中，终端102可以是移动设备、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元，远程单元、用户代理、移动客户端等等。
具体的，网络设备101可用于在网络设备控制器(未示出)的控制下，通过无线接口103与用户设备102通信。在一些实施例中，所述网络设备控制器可以是核心网的一部分，也可以集成到网络设备101中。网络设备101与网络设备101之间也可以通过回程(blackhaul)接口104(如X2接口)，直接地或者间接地，相互通信。
频域资源在各个运营商之间进行分配，一个band(频段)下的不同频域资源可能分配给不同的运营商。如下图1B所示，载波A和载波C分配给运营商A，载波B分配给运营商B。如果用户设备在载波A搜索到SSB1，但是SSB1没有关联RMSI，则运营商A的网络设备通过该SSB1中的PBCH指示小区定义的SSB(cell defining SSB)的频域位置。假如在载波A上的SSB可以指示从载波A到载波C上的cell defining SSB的频域位置，由于载波B由于是运营商B所使用的载波，其包含的cell defining SSB的频域位置不会被运营商A的网络设备所指示，那么载波B所在的频域资源不存在用户设备需要搜索的关联RMSI的SSB。如果用户设备搜索载波B所在的资源，会导致用户设备在不存在SSB传输的频域范围内做无用的搜索，增长了用户设备的初始搜索过程所需要的时间，进而增长了用户设备初始接入网络设备所需要的时间。
可见，本申请中，网络设备通过给用户设备指示某些频域范围内SSB的频域位置，从而避免了用户设备在不存在SSB的频域范围内做无用的搜索，加快了用户设备的初始搜索过程，进而减少了初始搜索过程中的功率消耗，以及有助于用户设备搜索不同运营商的频域范围内的SSB。
需要说明的，图1示出的无线通信系统100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。

基于前述无线通信系统100、用户设备200以及网络设备300分别对应的实施例，本申请实施例提供了指示方法。
请参见图4，图4为本申请实施例提供的一种指示方法的流程示意图，包括以下步骤：
步骤401：网络设备向用户设备发送指示，所述指示用于指示在第一频域范围内SSB的第一频域位置。
进一步地，所述SSB关联RMSI。
其中，RMSI承载在物理下行共享信道(Physical Downlink Shared Channel，PDSCH)上，PDSCH的下行控制信息(Downlink Control Infornation，DCI)承载在物理下行控制信道(Physical Downlink Control CHannel，PDCCH)上，PDCCH所在的时频资源位置通过物理广播信道(Physical Broadcast Channel，PBCH)来指示，PBCH还指示其所在的SSB是否关联RMSI。因此可通过关联RMSI的SSB来获取RMSI。
具体地，频域资源在各个运营商之间进行分配，一个band下的不同频域资源可能分配给不同的运营商。如下图1B所示，载波A和载波C分配给运营商A，载波B分配给运营商B。如果用户设备在载波A搜索到SSB1，但是SSB1没有关联RMSI，则运营商A的网络设备通过该SSB1中的PBCH指示cell defining SSB的频域位置。假如在载波A上的SSB可以指示从载波A到载波C上的cell defining SSB的频域位置，由于载波B由于是运营商B所使用的载波，其包含的cell defining SSB的频域位置不会被运营商A的网络设备所指示，那么载波B所在的频域资源不存在用户设备需要搜索的关联RMSI的SSB。如果用户设备搜索载波B所在的资源，会导致用户设备在不存在SSB传输的频域范围内做无用的搜索，增长了用户设备的初始搜索过程所需要的时间，进而增长了用户设备初始接入网络设备所需要的时间。
可见，本申请中，网络设备通过给用户设备指示某些频域范围内SSB的频域位置，从而避免了用户设备在不存在SSB的频域范围内做无用的搜索，加快了用户设备的初始搜索过程，进而减少了初始搜索过程中的功率消耗，以及有助于用户设备搜索不同运营商的频域范围内的SSB。
在本申请的一实施例中，所述网络设备向用户设备发送指示，所述指示用于指示在第一频域范围内SSB的第一频域位置，包括：
所述网络设备向所述用户设备发送第一消息，所述第一消息用于指示所述第一频域范围；
所述网络设备向所述用户设备发送第二消息，所述第二消息用于指示所述SSB的所述第一频域位置。
其中，第一消息和第二消息可以携带在网络设备给用户设备发送的下行数据中，也可以携带在网络设备给用户设备发送的下行消息中等等，在此不作限定。
其中，网络设备可一起将第一消息和第二消息一起发送给用户设备，也可以分开将第一消息和第二消息发给用户设备。
在本申请的一实施例中，所述网络设备通过物理广播信道PBCH中的第一信息域承载所述第二消息，所述第一信息域包括RMSI的控制信息资源集合(Control Resource Set，CORESET)信息域。
具体地，PBCH中包括RMSI的CORESET信息域，在现有技术中，这个信息域是用于指示SSB的频域位置的信息域。在本申请中，由于PBCH所在的SSB没有关联RMSI，所以这个没有关联RMSI的SSB对应的PBCH的这个信息域是空闲域，因此在本申请中，网络设备使用这个信息域指示关联RMSI的SSB的频域位置。
在本申请的一实施例中，所述网络设备通过物理广播信道PBCH中的除了所述第一信息域之外的第二信息域承载所述第一消息。
在本申请的一实施例中，所述第二信息域包括以下至少一种：PRB grid offset信息域中的保留值、RMSI的子载波间隔SCS信息、小区禁止接入指示信息(Cell Barred)、同频重选信息(IntraFreq Reselection)。
其中，具体地，PBCH中承载用于指示PBCH所在的SSB是否关联RMSI的信息。现有技术中，网络设备可通过PBCH的PRB grid offset信息域中的保留值指示不存在RMSI。在6MHZ以下，PRB grid offset信息域包括5个比特位，5个比特位总共有1到32个编码位，这32个编码位中有24个编码位已被使用，还剩8个编码位空闲。
其中，RMSI SCS是用于接收RMSI和后续随机接入和接收其他系统信息的信息。如果PBCH所在的SSB没有关联RMSI，这个没有关联RMSI的SSB对应的PBCH的RMSI SCS是空闲的，因此在该种情况下，可使用RMSI SCS指示其他信息。
其中，Cell Barred用于指示该小区是否允许接入。如果PBCH所在的SSB没有关联RMSI，这个没有关联RMSI的SSB对应的PBCH的Cell Barred是空闲的，因此在该种情况下，可使用Cell Barred指示其他信息。
其中，IntraFreq Reselection用于指示是否允许同频重选。如果PBCH所在的SSB没有关联RMSI，这个没有关联RMSI的SSB对应的PBCH的IntraFreq Reselection是空闲的，因此在该种情况下，可使用IntraFreq Reselection指示其他信息。
可见，在PBCH所在的SSB没有关联RMSI的情况下，网络设备可使用PRB grid offset信息域中的保留值、RMSI SCS、Cell Barred、IntraFreq Reselection中的至少一种来指示频域范围。
在本申请的一实施例中，所述第二消息包括频域位置信息，所述频域位置信息包括位置信息，所述频域位置信息指示SSB在所述第一频域范围内同步栅格的绝对位置；或者，所述频域位置信息包括频域偏移，所述频域偏移是所述第一频域位置所在的同步栅格与PBCH所在的SSB对应同步栅格之间的间隔。
其中，上述间隔可以是同步栅格的个数，也可以是频域宽度等等，在此不作限定。
基于前述无线通信系统100、用户设备200以及网络设备300分别对应的实施例，本申请实施例提供了检测方法。
请参见图5，图5为本申请实施例提供的一种指示方法的流程示意图，包括以下步骤：
步骤501：用户设备接收来自网络设备的指示，所述指示用于指示在第一频域范围内SSB的第一频域位置。
步骤502：所述用户设备基于所述指示检测SSB。
进一步地，所述SSB关联RMSI。
其中，RMSI承载在PDSCH上，PDSCH的DCI承载在PDCCH上，PDCCH所在的时频资源位置通过PBCH来指示，PBCH还指示其所在的SSB是否关联RMSI。因此可通过关联RMSI的SSB来获取RMSI。
具体地，频域资源在各个运营商之间进行分配，一个band下的不同频域资源可能分配 给不同的运营商。如下图1B所示，载波A和载波C分配给运营商A，载波B分配给运营商B。如果用户设备在载波A搜索到SSB1，但是SSB1没有关联RMSI，则运营商A的网络设备通过该SSB1中的PBCH指示cell defining SSB的频域位置。假如在载波A上的SSB可以指示从载波A到载波C上的cell defining SSB的频域位置，由于载波B由于是运营商B所使用的载波，其包含的cell defining SSB的频域位置不会被运营商A的网络设备所指示，那么载波B所在的频域资源不存在用户设备需要搜索的关联RMSI的SSB。如果用户设备搜索载波B所在的资源，会导致用户设备在不存在SSB传输的频域范围内做无用的搜索，增长了用户设备的初始搜索过程所需要的时间，进而增长了用户设备初始接入网络设备所需要的时间。
具体实现中，用户设备基于所述指示检测SSB，包括：在进行SSB检测时，用户设备直接在第一频域范围内的第一频域位置上进行SSB检测。
可见，本申请中，网络设备通过给用户设备指示某些频域范围内SSB的频域位置，从而避免了用户设备在不存在SSB的频域范围内做无用的搜索，加快了用户设备的初始搜索过程，进而减少了初始搜索过程中的功率消耗，以及有助于用户设备搜索不同运营商的频域范围内的SSB。
在本申请的一实施例中，所述用户设备接收来自网络设备的指示，所述指示用于指示在第一频域范围内SSB的第一频域位置，包括：
所述用户设备接收来自所述网络设备的第一消息，所述第一消息用于指示所述第一频域范围；

具体地，PBCH中包括RMSI的CORESET信息域，在现有技术中，这个信息域是用于指示SSB的频域位置的信息域。在本申请中，由于PBCH所在的SSB没有关联RMSI，所以这个没有关联RMSI的SSB对应的PBCH的这个信息域是空闲域，因此在本申请中，网络设备使用这个信息域指示关联RMSI的SSB的频域位置。
在本申请的一实施例中，所述网络设备通过物理广播信道PBCH中的除了所述第一信息域之外的第二信息域承载所述第一消息。
在本申请的一实施例中，所述第二信息域包括以下至少一种：物理资源块PRB栅格偏移grid offset信息域中的保留值、RMSI的子载波间隔SCS信息、小区禁止接入指示信息、同频重选信息。
其中，具体地，PBCH中承载用于指示PBCH所在的SSB是否关联RMSI的信息。现有技术中，网络设备可通过PBCH的PRB grid offset信息域中的保留值指示不存在RMSI。在6MHZ以下，PRB grid offset信息域包括5个比特位，5个比特位总共有1到32个编码位，这32个编码位中有24个编码位已被使用，还剩8个编码位空闲。
其中，RMSI SCS是用于接收RMSI和后续随机接入和接收其他系统信息的信息。如果PBCH所在的SSB没有关联RMSI，这个没有关联RMSI的SSB对应的PBCH的RMSI SCS是空闲的，因此在该种情况下，可使用RMSI SCS指示其他信息。
其中，Cell Barred用于指示该小区是否允许接入。如果PBCH所在的SSB没有关联RMSI，这个没有关联RMSI的SSB对应的PBCH的Cell Barred是空闲的，因此在该种情况下，可使用Cell Barred指示其他信息。
其中，IntraFreq Reselection用于指示是否允许同频重选。如果PBCH所在的SSB没有关联RMSI，这个没有关联RMSI的SSB对应的PBCH的IntraFreq Reselection是空闲的，因此在该种情况下，可使用IntraFreq Reselection指示其他信息。
可见，在PBCH所在的SSB没有关联RMSI的情况下，网络设备可使用PRB grid offset信息域中的保留值、RMSI SCS、Cell Barred、IntraFreq Reselection中的至少一种来指示频域范围。
在本申请的一实施例中，所述第二消息包括频域位置信息，所述频域位置信息包括位置信息，所述频域位置信息指示SSB在所述第一频域范围内同步栅格的绝对位置；或者，所述频域位置信息包括频域偏移，所述频域偏移是所述第一频域位置所在的同步栅格与PBCH所在的SSB对应同步栅格之间的间隔。
其中，上述间隔可以是同步栅格的个数，也可以是频域宽度等等，在此不作限定。
