可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
出于不同的考虑，不同的国家的频谱监管以及分配机构对于频谱的规划与分配有不同，例如3.5GHz在中国为授权的NR频段，而在美国则为非授权频段；又例如，37GHz中国为可能会划分为授权的NR频段，而在美国则可能会划分为非授权频段。
上述频谱分配上的差异可能会导致终端设备在不同的国家或地区漫游时，在同一频段上(如3.5GH频段上)，有的国家或地区部署的为非授权频段的系统，而有的国家或地区部署的为授权频段系统。在非授权频段上，由于LBT机制，承载同步信号和物理广播信道(Physical Broadcast Channel，PBCH)的同步信号块(Synchronous Signal Block，SSB或SS Block)的发送可能存在概率性的成功发送或不成功发送；与SSB关联的剩余最小系统信 息(Remaining Minimum System Information，RMSI)也可能存在概率性的成功发送或不成功发送；终端设备的上行传输需要采用LBT机制；终端设备的上行传输需要满足功率谱密度的限制要求等。因此，终端设备在非授权频段系统中进行通信时所执行的操作与其在授权频段系统中执行的操作可能会有不同。
这样，当终端设备在不同的国家或地区漫游时，若不同国家或地区之间的频谱划分不同，则终端设备则无法有效地进行通信。
因此，本申请实施例提出，因此，网络设备通过向终端设备指示该网络设备的工作频段属性或系统属性，使得该终端设备根据网络设备指示的工作频段属性确定该网络设备的工作频段为授权频段还是非授权频段，从而能够相应地执行授权频段或非授权频段上的操作，或者，该终端设备根据网络设备指示的系统属性确定该网络设备工作于授权频段系统还是非授权频段系统，从而能够相应地执行授权频段系统或非授权频段系统中的操作，从而实现有效的数据传输。
图2是本申请实施例的通信方法的流程交互图。图2中所示的终端设备例如可以为图1中所示的终端设备120。图2中所示的网络设备例如可以为图1中所示的网络设备110。如图2所示，该通信方法可以包括以下部分或全部内容：
在210中，网络设备向终端设备发送指示信息，该指示信息用于指示该网络设备的工作频段属性或系统属性。
其中，该工作频段属性用于表示该网络设备的工作频段为授权频段还是非授权频段，该系统属性用于表示该网络设备工作于授权频段系统还是非授权频段系统。
在220中，该终端设备接收该网络设备发送的该指示信息。
在230中，该终端设备基于该工作频段属性或该系统属性，与该网络设备进行通信。
在240中，该网络设备基于该工作频段属性或该系统属性，与该终端设备进行通信。
具体地，该终端设备接收网络设备发送的指示信息，假设该指示信息用于指示该网络设备的工作频段属性。其中，网络设备的工作频段属性表示该网络设备支持的频段为授权频段(licensed frequency bands)还是非授权频段(unlicensed frequency bands)。若该网络设备的工作频段为授权频段，则该终端设备执行授权频段上相应的通信操作，例如基于网络设备配置的资源与网络设备之间进行数据传输等等；若该网络设备的工作频段为非授权频段，则该终端设备执行非授权频段上相应的通信操作，例如基于LBT方式，侦听信道是否空闲，并在确定信道为空闲后进行数据传输等等。
终端设备接收网络设备发送的指示信息，假设该指示信息用于指示该网络设备的系统属性。其中，网络设备的系统属性表示该网络设备所在的系统为授权频段系统(unlicensed NR系统)还是非授权频段系统(licensed NR系统)。若该网络设备工作于授权频段系统，则该终端设备执行授权频段上相应的通信操作，例如基于网络设备配置的资源与网络设备之间进行数据传输等等；若该网络设备工作于非授权频段系统，则该终端设备执行非授权频段上相应的通信操作，例如基于LBT方式，侦听信道是否空闲，并在确定信道为空闲后进行数据传输等等。
应理解，该网络设备的工作频段为授权频段，可以理解为，该网络设备工作于授权频段系统；该网络设备的工作频段为非授权频段，可以理解为，该网络设备工作于非授权频段系统。
因此，网络设备通过向终端设备指示该网络设备的工作频段属性或系统属性，该终端设备根据网络设备指示的工作频段属性确定该网络设备的工作频段为授权频段还是非授权频段，从而能够相应地执行授权频段或非授权频段上的操作，或者，该终端设备根据网络设备指示的系统属性确定该网络设备工作于授权频段系统还是非授权频段系统，从而能够相应地执行授权频段系统或非授权频段系统中的操作，从而实现有效的数据传输。
可选地，该指示信息包括但不限于以下中的任意一种：同步信号块(Synchronizing Signal Block，SSB)中的主同步信号(Primary Synchronization Signal，PSS)、该SSB中的辅同步信号(Secondary synchronization signal，SSS)、该SSB中的PBCH、无线资源控制(Radio Resource Control，RRC)信令、RMSI、其他系统信息(Other System Information，OSI)。
也就是说，网络设备通过上述的PSS、SSS、PBCH、RMSI、OSI等信息向终端设备指示该网络设备的工作频段属性或系统属性。具体地，网络设备可以通过这些信息隐式或者显示地指示该网络设备的工作频段属性或者系统属性。
方式1 隐式指示
下面以该指示信息为PSS和PBCH为例，具体描述网络设备如何进行隐式指示。
可选地，该指示信息为该PSS。
其中，在210之前，该网络设备根据该网络设备的该工作频段属性或该系统属性，确定用于生成该指示信息的序列，并基于该序列生成该指示信息。
相应地，在220之前，该终端设备根据用于生成该指示信息的序列，确定该网络设备的该工作频段属性或系统属性。
其中，该网络设备的工作频段为授权频段或该网络设备工作于授权频段系统时，用于生成该指示信息的序列为第一序列，该网络设备的工作频段为 非授权频段或该网络设备工作于非授权频段系统时，用于生成该指示信息的序列为第二序列，该第一序列与该第二序列为不同序列。
也就是说，网络设备的工作频段为授权频段和非授权频段时，该网络设备生成该PSS所使用的序列不同；或者说，该网络设备工作于授权频段系统和非授权频段系统时，该网络设备生成该PSS所使用的序列不同。终端设备根据生成该PSS的序列，确定该网络设备的工作频段属性或系统属性。
进一步地，可选地，该不同序列的循环移位值不同。
举例来说，该网络设备的工作频段为授权频段或该网络设备工作于授权频段系统时，用于生成该PSS的第一序列为：
d PSS(n)＝1-2x(m)，
其中，
Figure PCTCN2018079358-appb-000001
0≤n＜127。
其中，x(i+7)＝x((i+4)+x(i))mod2；[x(6)x(5)x(4)x(3)x(2)x(1)]＝[1 1 1 0 1 1 0]。
可以看出，生成PSS采用的为m序列，频率上的三个循环移位值分别为0、43和86。
而该网络设备的工作频段为非授权频段或该网络设备工作于非授权频段系统时，用于生成该PSS的第二序列为：
d PSS(n)＝1-2x(m),
其中，
Figure PCTCN2018079358-appb-000002
0≤n＜127。
这时，频率上的三个循环移位值分别为0+offset、43+offset和86+offset。这里假设offset＝22，则三个循环移位值分别为22、65和108。
那么，终端设备通过检测网络设备发送的该PSS，确定生成该PSS的序列d PSS，由于该网络设备的工作频段属性不同或系统属性不同时，m序列不同，从而序列d PSS也不同，因此，该终端设备可以根据不同的序列d PSS确定该网络设备的工作频段属性或系统属性。
可选地，该指示信息为该PBCH。
其中，在210之前，该网络设备根据该网络设备的该工作频段属性或该系统属性，确定用于对该指示信息进行调制的解调参考信号DMRS序列，并根据该DMRS序列对该指示信息进行调制。
相应地，在220之前，终端设备根据解调该指示信息所使用的解调参考信号(Demodulation Reference Signal，DMRS)序列，确定所述网络设备的所述工作频段属性或所述系统属性。
其中，该网络设备的工作频段为授权频段或该网络设备工作于授权频段系统时，用于生成该指示信息的序列为第一序列，该网络设备的工作频段为非授权频段或该网络设备工作于非授权频段系统时，用于生成该指示信息的 序列为第二序列，该第一序列与该第二序列为不同序列。
也就是说，该网络设备的工作频段为授权频段和非授权频段时，网络设备对该指示信息进行调制的DMRS序列不同；或者说，该网络设备工作于授权频段系统和非授权频段系统时，网络设备对该指示信息进行调制的DMRS序列不同。终端设备根据成功解调该PBCH的DMRS序列，确定该网络设备的工作频段属性或系统属性。
进一步地，可选地，该不同的DMRS序列的初始加扰序列不同。
举例来说，该网络设备的工作频段为授权频段或该网络设备工作于授权频段系统时，用于生成该PBCH的第一DMRS序列为：
Figure PCTCN2018079358-appb-000003
其中，假设该r(m)序列的初始加扰序列为：
Figure PCTCN2018079358-appb-000004
其中，
Figure PCTCN2018079358-appb-000005
n hf为传输PBCH的子帧中的半帧编号，i SSB为SSB索引的最少有效比特数。
而该网络设备的工作频段为非授权频段或该网络设备工作于非授权频段系统时，用于生成该PBCH的第二序列为：
Figure PCTCN2018079358-appb-000006
但是，这时，该r(m)序列的初始加扰序列设置为：
Figure PCTCN2018079358-appb-000007
其中，
Figure PCTCN2018079358-appb-000008
n hf为传输PBCH的子帧中的半帧编号，i SSB为SSB索引的最少有效比特数。
那么，终端设备通过检测网络设备发送的该PBCH，确定生成该PBCH的序列r(m)，由于该网络设备的工作频段属性不同或系统属性不同时，序列r(m)中的初始序列不同，从而该序列r(m)也不同，因此，该终端设备能够根据不同的r(m)序列确定该网络设备的工作频段属性或系统属性。
应理解，在方式1中，仅以生成PSS使用的m序列，以及调制或解调PBCH的DMRS序列为例，描述了网络设备如何进行隐式指示，但本申请并不限于此，采用其他物理信道或其他序列来进行隐式指示的方式，也应落在本申请的保护范围之内。
方式2 显示指示
可选地，该指示信息携带属性标识，该属性标识用于表示该网络设备的工作频段属性或系统属性。
其中，在210之前，该网络设备根据该网络设备的该工作频段属性或该 系统属性，确定该指示信息中的携带的该属性标识。
相应地，在220之前，该终端设备根据该指示信息中的携带的该属性标识的值，确定该网络设备的该工作频段属性或该系统属性。
其中，该网络设备的工作频段为授权频段或该网络设备工作于授权频段系统时，该属性标识的值为第一数值，该网络设备的工作频段为非授权频段或该网络设备工作于非授权频段系统时，该属性标识的值为第二数值，该第一数值与该第二数值不同。
也就是说，该网络设备的工作频段分别为授权频段和非授权频段时，该指示信息中携带的属性标识的值是不同的；该网络设备工作于授权频段系统和非授权频段系统时，该指示信息中携带的属性标识的值也不同。终端设备根据该指示信息中携带的该属性标识的值，确定该网络设备的工作频段属性或系统属性。
例如，可以采用PBCH中的一个预留比特位，比如PBCH中的有效载荷(payload)字段中的预留比特位，当该比特位上的值为1时，指示该网络设备的工作频段为非授权频段或该网络设备的系统为非授权频段系统。当该比特位上的值为0时，指示该网络设备的工作频段为授权频段或该网络设备的系统为授权频段系统。
又例如，在PBCH、RMSI或OSI中添加该属性标识，当该属性标识的取值为1时，指示该网络设备的工作频段为非授权频段或该网络设备的系统为非授权频段系统。当该属性标识的取值为0时，指示该网络设备的工作频段为授权频段或该网络设备的系统为授权频段系统。
可选地，若该网络设备的工作频段为非授权频段或该网络设备工作于非授权频段系统，则240中，该终端设备与该网络设备进行通信，包括：该终端设备基于LBT的方式与该网络设备进行通信。
由于该网络设备的工作频段为非授权频段或该网络设备工作于非授权频段系统，因此终端设备需要基于LBT的方式，侦听信道是否空闲，并在确定信道为空闲后与网络设备进行通信。
这样，即使终端设备在不同的国家或地区漫游时，不同国家或地区之间的频谱划分不同，那么终端设备也可以有效地获取当前待接入网络的频段时非授权频段还是授权频段，从而执行相应的操作，实现在不同频段上有效的数据传输。
