背景技术
双连接(Dual Connectivity，DC)场景，例如，演进的通用移动通信***(Universal Mobile Telecommunications System，UMTS)陆面无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)与新空口(New Radio，NR)节点之间的双连接，或者两个NR节点之间的双连接，或者两个长期演进(Long Term Evolution，LTE)节点之间的双连接。一个节点扮演了主基站(Master Node，MN)，另一个扮演了辅基站(Secondary Node，SN)。MN和SN通过网络接口相连接。
多连接(Multiple Connectivity，MC)场景，在双连接基础上，一个MN可以和多个SN组成多连接。
为了解决终端设备耗电较高的问题，引入了节能信号的概念。节能信号通常情况下会携带用户设备(User Equipment，UE)的标识(Identity，ID)信息，UE通过检测节能信号，并做相关匹配来判断是否为与自己对应的节能信号，例如，节能信号可以是叫醒信号(Wake Up Signal，WUS)信号。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，并 不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
双连接DC场景介绍如下：
几种节点解释如下：
演进型基站(evolutional Node B，eNB)：LTE***下基站。
5G基站(generation Node B，gNB)：面向UE提供NR的用户面和控制面的节点，通过NG接口连接到5G核心网(5G Core Network，5GC)。
en-gNB：面向UE提供NR用户面和控制面的节点，在EN-DC架构中扮演辅节点。
ng-eNB：面向UE提供演进的陆地无线接入网(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)用户面和控制面的节点，通过NG接口连接到5GC。
NG-C：NG-RAN和5GC之间的控制面接口；
NG-U：在NG-RAN和5GC之间的用户面接口；
几种架构定义：
MR-DC：演进的UMTS陆面无线接入(Evolved Universal Terrestrial Radio Access，E-UTRA)与NR节点之间的双连接。在MR-DC中，其中一个节点扮演了主基站MN，另一个扮演了辅基站SN。MN和SN通过网络接口相连接，其中至少MN连接到核心网(5GC或演进分组核心网(Envolved Packet Core，EPC))。
MR-DC包含以下几种架构：
E-UTRA-NR双连接(EN-DC)：如图1所示，在这种架构下，UE连接到一个作为MN的eNB和一个作为SN的en-gNB。其中eNB(即MN)通过S1接口连接到演进分组核心网EPC，通过X2接口连接到en-gNB(即SN)。而en-gNB也可能通过S1-U接口连接到EPC，以及X2-U接口连接到其他en-gNB。
NG-RAN E-UTRA-NR双连接(NGEN-DC)：如图2所示，在这种架构下，UE连接到一个作为MN的ng-eNB，并连接到一个作为SN的gNB。其中 ng-eNB连接到5GC和gNB，其中nb-eNB拥有LTE的协议层功能，而gNB通过Xn接口连接到ng-eNB。
NR-E-UTRA双连接(NE-DC)：如图3所示，在NE-DC中，UE连接到一个作为MN的gNB以及一个作为SN的ng-eNB。其中gNB连接到5GC，而ng-eNB通过Xn接口连接到gNB。
NR-DC：UE与两个gNB连接，其中一个gNB作为主节点，另外一个gNB作为辅节点；
LTE-DC：UE与两个eNB连接，其中一个eNB作为主节点，另一个eNB作为辅节点。
在本发明实施例中，DC包括以上MR-DC、NR-DC和LTE-DC3个大分类。
关于双连接用户面承载介绍如下：
从UE侧的角度来看，双连接存在三种承载类型：主小区组(Master Cell Group，MCG)承载、SCG承载和***(split)承载。
从网络侧的角度来看，每个承载(MCG，SCG与split承载)可以被终止在MN或者SN。网络侧协议终止选择如图4和图5所示，分别针对EN-DC与MR-DC和5GC(NGEN-DC与NE-DC)。
关于节能(Power Saving)介绍如下：
为了解决终端设备耗电较高的问题，引入了节能信号的概念。目前有以下两种节能方案。节能信号通常情况下会携带UE的标识(ID)信息，UE通过检测节能信号，并做相关匹配来判断是否为与自己对应的节能信号，举例来讲，节能信号可以是叫醒信号WUS信号，或所述UE的信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)。
方式一：UE周期性接收节能信号。网络会配置节能信号发送的周期信息，或UE按照其他配置的周期，比如非连续接收(Discontinuous Reception，DRX)周期，或半静态调度(Semi-persistent Scheduling，SPS)周期，侦听节能信号。如果UE接收到了与自己对应的节能信号，那么UE将在接收到节能信号后， 将持续侦听n个时隙和/或子帧和/或符号的物理层下行控制信道PDCCH，其中n为大于等于1的整数。如果UE没有接收到与自己对应的节能信号，那么UE将进入节能状态，即不再侦听PDCCH。具体流程如图6所示。
方式二：如图7所示，UE根据节能信号指示判断是否要侦听PDCCH。在这种情况下，UE需要一直侦听节能信号，这里假定UE侦听节能信号的耗电量非常低。当UE检测到与其对应的节能信号后，UE将持续侦听n个时隙和/或子帧和/或符号的PDCCH，n为大于等于1的整数。之后UE会进入到节能状态，即不再侦听PDCCH。
如图8所示，UE在MN对应的小区组即主小区组MCG上侦听节能信号的位置，与SN对应的小区组即辅小区组SCG上侦听节能信号的位置不同，导致UE在t1(t3，t5)时刻侦听节能信号进入节能状态后，还需要在t2(t4，t6)时刻醒来。而现有技术无法解决UE多次醒来侦听节能信号的问题。
综上，在DC场景下，如果每个节点单独配置节能信号，可能由于各自配置的时间点不同，多次唤醒UE监听而造成UE的电量损耗。由于主、辅节点是双连接的基站，因此可以仅在其中一个节点上配置节能信号，使得UE在没有数据接收时仅监听一套节能信号，避免监听多个小区上的节能信号造成UE电量损耗。
本申请实施例提供了信号传输方法及装置，用以使得UE仅监听一个CG的节能信号，避免多次唤醒UE监听节能信号而造成UE的电量损耗。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。

下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是，本申请实施例的展示顺序仅代表实施例的先后顺序，并不代表实施例所提供的技术方案的优劣。
本发明实施例的核心思想为：网络侧节点，例如MN，配置UE仅监听一个CG上的节能信号。
在网络侧：
发送节能信号的CG可能是MCG或者SCG；
MCG告知或触发发送节能信号的CG，开启节能信号发送功能；
MCG告知其他CG，挂起与该UE的连接；
MCG向UE发送节能信号配置信息；UE收到该配置信息后，应用该配置信息，保持与配置的发送节能信号的CG的连接，即只监听该CG下的节能信号，挂起与其余CG的连接，针对其他CG不进行数据接收也不进行节能信号监听。
网络侧节点有数据到达时：
如果有数据到达的网络侧节点不包含发送节能信号的CG，有数据到达的网络侧节点需要通过节点间信令告知该CG，从而触发该CG发送节能信号给UE；
进一步，还可以：有数据到达的网络侧节点或者MN，通过节点间信令，恢复或删除与所述UE挂起连接的CG；
或者，有数据到达的网络侧节点向挂起的CG分流数据，隐式恢复与所述 UE挂起连接的CG。
如果有数据到达的网络侧节点包含发送节能信号的CG，除了触发该CG发送节能信号给UE之外，进一步还可以：
有数据到达的网络侧节点通过节点间信令，恢复或删除之前挂起的CG；
或者，有数据到达的网络侧节点向之前挂起的CG分流数据，隐式的恢复之前挂起的CG。
其中，所述网络侧节点为主基站MN或辅基站SN。
可选地，所述节点间信令是有数据到达的所述网络侧节点直接向发送节能信号的CG所在的网络侧节点发送的，或者是经过MN中转的。
相应地，在UE侧：
UE在监听节能信号时，如果收到属于自己的节能信号，可以是：
UE在该CG上开始监听PDCCH，但仍挂起与其余CG的连接；直到收到重新恢复CG或者重配CG的配置后，根据网络侧指示恢复双连接(DC)或多连接MC工作；
或者，UE在该CG上开始监听PDCCH，并主动恢复与挂起的CG的连接(监听挂起的CG上的PDCCH)。

步骤903：MN向UE发送节能信号配置信息，通知UE仅监听MCG上节能信号。该信息可以使用RRC连接重配消息(RRC Connection Reconfiguration/RRC Reconfiguration)承载。节能信号配置信息包括但不限于以下内容：节能信号在MN上的资源位置信息，例如节能信号的周期、节能信号的频域位置等；该配置信息还可以包括节能信号的ID信息，可选的，该 ID信息可以用于表示节能信号的扰码信息，或该ID信息可以用于表示计算节能信号的符号偏移量信息，该同一ID信息可以发送给一个UE，也可以发送给多个UE。
步骤904：UE收到MN发送的节能信号配置信息后，执行节能信号的配置过程，并按照节能信号配置信息，进入节能状态开始监听MCG的节能信号。UE在配置成功后可以向MN发送RRC连接重配成功(RRC Connection Reconfiguration Complete/RRC Reconfiguration Complete)消息。

本申请是参照根据本申请实施例的方法、设备(***)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、 嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
