需要说明的是，本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号，均为经用户授权或者经过各方充分授权的，且相关数据的收 集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
首先，对本申请所涉及的名词进行说明。
省电信号：终端的主接收机或者主收发机在无需处理数据的情况下可以处于睡眠状态，接入网设备通过该省电信号可以唤醒主接收机或主收发机，以便于终端在无需处理数据的情况下节省资源。
主接收机：终端若需要接收接入网设备发送的下行数据，则可以通过该主接收机接收下行数据，并且还可以通过该主接收机对下行数据进行处理。需要说明的是，终端还包括对应的辅接收机，该辅接收机可以接收接入网设备发送的省电信号。

其次，对本申请的应用场景进行说明：
图1示出了本申请一个示例性实施例提供的通信***的框图，该通信***可以包括：终端10和接入网设备20。
终端10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为接入网设备。接入网设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备20的数量可以有多个，两个邻近的接入网设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的接入网设备20之间进行波束报告发送，也即与不同的接入网设备20建立连接。
该接入网设备20可以包括各种形式的宏基站、微基站、中继站、接入点等等。在采用不同的无线接入技术的***中，具备接入网设备功能的设备的名称 可能会有所不同，例如在5G NR(New Radio，新空口)***中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。
本申请实施例中的“5G NR***”也可以称为5G***或者NR***，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR***，也可以适用于5G NR***后续的演进***。
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。
步骤202：终端通过至少一个频域单元接收接入网设备发送的省电信号，省电信号用于指示是否唤醒终端的主接收机或主收发机，主接收机用于处理下行数据，主收发机用于处理上行数据和/或下行数据。
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，该省电信号为WUS(Wake up signal，唤醒信号)信号、LP WUS(Low Power Wake up signal，低功耗唤醒信号)信号、PEI(Paging Early Indication，寻呼提前指示)信号、DCP(DCI for power saving，省电DCI)信号或者其他信号，本申请实施例不做限定。
在本申请实施例中，接入网设备和终端之间配置有至少一个频域单元，则接入网设备可以通过至少一个频域单元向终端发送省电信号，终端即可对至少一个频域单元进行检测，进而可以通过至少一个频域单元接收接入网设备发送的省电信号。
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。
在一些实施例中，接入网设备为终端配置至少一个载波。其中，接入网设备向终端发送第一配置信令，该第一配置信令用于配置至少一个载波，终端接收接入网设备发送的第一配置信令后，即可确定接入网设备配置的至少一个载波。
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。
在一些实施例中，若接入网设备未通过第一配置信令为终端配置至少一个载波，也就是说终端在未接收到接入网设备发送的第一配置信令的情况下，采用默认方式确定至少一个载波。
可选地，终端通过默认方式确定至少一个载波包括：
(1)将第一小区对应的载波确定为至少一个载波。
其中，该第一小区为主小区、主辅小区或者其他小区。
在本申请实施例中，终端可以将第一小区对应的载波确定为至少一个载波。例如，将主小区对应的载波确定为至少一个载波。或者，将主辅小区对应的载波确定为至少一个载波。
(2)将小区标识最高或最低对应的载波确定为至少一个载波。
