网络设备向用户设备发送的配置信息用于配置唤醒信号对应的频域位置。用户设备接收到配置信息后，获取了唤醒信号对应的频域位置。唤醒信号对应的频域位置可以为以下一种：
同步信号块对应的频域位置；控制资源集合CORESET#0对应的频域位置；初始BWP对应的频域位置；以及激活BWP对应的全部或部分的频域位置。
在本申请的一种实施方式中，唤醒信号对应的频域位置为同步信号块对应的频域位置。这样，可以使得处于RRC空闲状态的用户设备102在使用同步信号块对应的频域位置接收同步信号块、并且基于同步信号块完成同步之后，无需进行射频处理参数的调整，继续使用此频域位置接收唤醒信号，从而降低用户设备接收唤醒信号的处理复杂度。
在本申请的一种实施方式中，唤醒信号对应的频域位置为控制资源集合CORESET#0对应的频域位置。这样，可以使得处于RRC空闲状态的用户设备102在接收同步信号完成同步、并且使用CORESET#0对应的频域位置接收CORESET#0中的下行控制信息(Downlink Control Information，DCI)之后，无需进行射频处理参数的调整，继续使用此频域位置接收唤醒信号。

示例的，所述唤醒信号对应的频域位置也可以为激活BWP对应的全部频域位置，即所述唤醒信号对应的频域位置为激活BWP对应的频域位置。这样，可以使得处于RRC连接状态的用户设备102在激活BWP上接收下行信息之后，无需进行射频处理参数的调整，并且无需进行带宽部分切换，继续使用此频域位置接收唤醒信号。
在本申请的一种实施方式中，唤醒信号对应的频域位置为激活BWP对应的部分频域位置。这样，可以使得处于RRC连接状态的用户设备102在激活BWP对应的部分频域位置上接收下行信息之后，无需进行射频处理参数的调整，继续使用此频域位置接收唤醒信号。
在一些可能的实施方式中，用户设备在辅小区中根据所述子载波间隔接收所述唤醒信号，所述唤醒信号对应的频域位置为第一激活带宽部分对应的频域位置。可选的，第一激活带宽部分(first active BWP)为专业术语，用于指示辅小区中的默认激活BWP。这样，可以使得辅小区内处于RRC连接状态的用户设备102在第一激活带宽部分对应的频域位置上接收下行信息之后，无需进行射频处理参数的调整，继续使用此频域位置接收唤醒信号。
在一些可能的实施方式中，所述唤醒信号对应的频域位置的中心位置可以为所述同步信号块对应的频域位置的中心位置，或者控制资源集合CORESET#0对应的频域位置的中心位置。
可选的，所述唤醒信号对应的频域位置的中心位置为所述同步信号块对应的频域位置的中心位置。这样，可以使得用户设备102在接收同步信号块执行同步之后，直接确定出唤醒信号对应的频域位置的中心位置，无需进行射频处理参数的调整，方便用户设备在后续接收唤醒信号。
在一些可能的实施方式中，所述唤醒信号对应的频域位置的中心位置为控制资源集合CORESET#0对应的频域位置的中心位置。这样可以使得用户设备102在接收CORESET#0中的下行控制信息(DCI)之后，直接确定出唤醒信号对应的频域位置的中心位置，无需进行射频处理参数的调整，方便用户设备在后续接收唤醒信号。
其中，唤醒信号对应的频域位置的端部位置可以设置有频域保护间隔。其中，频域位置的端部位置包括频域位置中最高频率对应的位置，以及频域位置中最低频率对应的位置。
步骤S302，网络设备101在所述频域位置上根据子载波间隔向用户设备102发送唤醒信号。
网络设备101向用户设备102发送的唤醒信号对应的子载波间隔为：同步信号(synchronizing signal)/物理广播信道块(physical broadcast channel，PBCH)块的子载波间隔。用户设备102根据所述子载波间隔接收唤醒信号。
用户设备102在所述频域位置上根据所述子载波间隔接收唤醒信号。
根据本申请提供的实施方式，用户设备102在接收同步信号块执行同步之后，便可根据同步信号块的子载波间隔在网络设备配置的频域位置上接收唤醒信号；无需进行基带参数的调整也无需进行射频参数的调整，直接使用所述子载波间隔对应的基带参数在所述频域位置上接收唤醒信号；可以有效降低用户设备接收唤醒信号的复杂度，节省用户设备的功耗。
在一些可能的实施方式中，步骤S301之前还包括:根据协议约定获取所述频域保护间隔。
在一些可能的实施方式中，还可以由网络设备102为用户设备配置所述频域保护间隔。
在一示例，如图4所示，步骤S301和步骤S302之前还包括：步骤S301’，网络设备101发送指示信息，用户设备102接收网络设备发送的指示信息；其中，所述指示信息用于指示所述频域保护间隔。即，网络设备先向用户设备102发送所述配置信息，再向用户设备102发送配置信息。
在另一示例中，如图5所示，步骤S301’在步骤S301之前，即网络设备先向用户设备102发送所述指示信息，再向用户设备102发送所述配置信息。
在另一示例中，网络设备101可以在同时发送所述配置信息和所述指示信息，即在同一信令中发送所述配置信息和所述指示信息。
本公开实施例提供了一种传输唤醒信号的方法，此方法包括：网络设备101在根据子载波间隔向用户设备102发送唤醒信号并且所述子载波间隔为同步信息块对应的子载波间隔，用户设备102确定未从网络设备接收到用于配置唤醒信号对应的频域位置的配置信息时，在预先设定的频域位置上根据所述子载波间隔接收唤醒信号。
在一些可能的实施方式中，预先设定的频域位置对于用户设备102而言是预设已存储的一种默认的频域位置，或者是根据协议约定获取的一固定的频域位置。
本公开实施例中的唤醒信号的子载波间隔为同步信号块的子载波间隔。
网络设备在需要向用户设备发送唤醒信号时，根据此子载波间隔向用户设备发送唤醒信号，用户设备根据此子载波间隔接收网络设备发送的唤醒信号。即网络设备和用户设备之间无需为针对传输唤醒型号协商采用何种子载波间隔，两者均单独的采用协议约定的子载波间隔即可。
例如，协议约定的用于向用户设备102发送唤醒信号的子载波间隔为15KHz，则网络设备采用15KHz向用户设备102发送唤醒信号，用户设备102采用15KHz接收网络设备用户设备102发送唤醒信号。
