图2示出了本申请一个示例性实施例提供的信号传输方法的流程图,示例性的可以应用于如图1所示的终端和接入网设备中,该方法包括以下内容中的至少部分内容:
步骤201:接入网设备通过至少一个频域单元向终端发送省电信号。

其中,频域单元用于指示频域位置。也就是说该频域单元用于指示发送省电信号在频域上的位置。该省电信号用于指示是否唤醒终端的主接收机或主收发机。也就是说接入网设备可以通过该省电信号唤醒终端的主接收机或主收发机,或者也可以通过该省电信号不唤醒终端的主接收机或主收发机。该主接收机用于处理下行数据。该主收发机用于处理上行数据和/或下行数据。

在一些实施例中,接入网设备通过至少一个频域单元向终端发送省电信号,终端在通过任一频域单元接收到接入网设备发送的省电信号后,即可确定需要唤醒终端的主接收机或主收发机。也可以理解为,本申请实施例中通过省电信号直接触发唤醒终端的主接收机或主收发机为隐式指示方式。
在另一些实施例中,若终端仍需要保持主接收机或主收发机为睡眠状态, 则接入网设备不会通过至少一个频域单元向终端发送省电信号,因此终端也会保持接收不到省电信号,因此终端会保持主接收机或主收发机为睡眠状态。
在一些实施例中,该省电信号中包括第一指示信息或第二指示信息,该第一指示信息指示终端唤醒主接收机或主收发机,该第二指示信息指示终端不唤醒主接收机或主收发机,若接入网设备向终端发送的省电信号包括的为第一指示信息,则终端根据该省电信号包括的第一指示信息唤醒主接收机或主收发机。若接入网设备向终端发送的省电信号包括的为第二指示信息,则终端根据该省电信号包括的第二指示信息保持主接收机或主收发机为睡眠状态。
本申请提供了一种通过至少一个频域单元接收省电信号的方案,该省电信号可以指示终端是否唤醒主接收机或主收发机,以便于确定是否通过主接收机或主收发机处理上行数据和/或下行数据,保证终端根据省电信号调整自身的工作状态,提高终端通信的准确性以及可靠性。
图2所示实施例对接入网设备和终端之间可以通过至少一个频域单元进行通信进行说明。而该频域单元可以包括不同的种类,下面对该频域单元的种类进行说明。
在一些实施例中,该频域单元为CC(Component Carrier,分量载波),或者,该频域单元为BWP(Band Width Part,部分带宽)。
下面针对不同的频域单元的种类进行说明。
第一种:该频域单元为CC。
在本申请实施例中,终端可以获取至少一个频域单元,并且该终端的至少一个频域单元可以采用不同的方式配置。

在本申请实施例中,接入网设备可以为终端配置至少一个载波,则接入网设备在确定至少一个载波后,向终端发送第一配置信令,该第一配置信令即可指示至少一个载波,终端根据接收的第一配置信令即可确定接入网设备为终端配置的至少一个载波。
可选地,该第一配置信令为动态信令、半静态信令或其他信令,本申请实 施例不做限定。
例如,该第一配置信令为RRC(Radio Resource Control,无线资源控制)信令、MAC CE(Media Access Control Control Element,媒体访问控制控制单元)、DCI(Downlink Control Information,下行控制信息)信令。
在另一些实施例中,终端还可以通过默认方式确定至少一个载波。
在本申请实施例中,终端的至少一个载波还可以由终端通过默认方式确定,也就是说无需接入网设备为终端配置至少一个载波,而是由终端自行确定至少一个载波。
