交叉引用

背景技术
在新空口(New Radio，NR)系统中，为了进一步提高用户设备(User Equipment，UE)的省电性能，引入了基于物理下行控制信道(Physical downlink control channel，PDCCH)的唤醒信号(Wake Up Signal，WUS)。WUS的作用是告知UE在特定的非连续接收(Discontinuous Reception，DRX)的持续时间(onDuration)期间，是否需要监听PDCCH。UE根据该指示，决定下一个DRX周期是否启动onDuration定时器，以及是否进行PDCCH监听。当没有数据的情况，UE可以不需要监听onDuration期间的PDCCH，相当于UE在整个DRX长周期(Long cycle)中都可以处于休眠状态，从而更进一步的省电。
网络侧设备(例如，基站)可以基于节能的目的，进入某些节能模式。比如，可以关闭基站部分或全部的上行传输和/或下行传输，并使基站持续监控来自终端UE或其它设备的唤醒信号(WUS)。当处于节能模式的基站接收到唤醒信号后，可以再转入其它基站工作状态，例如，基站完全开启，或转为浅度节能工作模式等。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的唤醒信号的信息确定方案进行详细地说明。
图2示出本申请实施例中的唤醒信号的信息确定方法的一种流程示意图，该方法200 可以由终端执行。换言之，所述方法可以由安装在终端上的软件或硬件来执行。如图2所示，该方法可以包括以下步骤。
S210，终端获取至少一个WUS配置信息。
在本申请实施例中，终端可以从网络侧设备接收所述至少一个WUS配置信息。例如，网络侧设备通过配置信令，为终端配置所述至少一个WUS配置信息。
或者，终端也可以根据协议约定的方式，获取所述至少一个WUS配置信息。例如，协议可以约定对于位于某种类型小区的终端的WUS配置信息，终端可以根据其当前所在小区的类型，获取对应的WUS配置信息。
S220，终端根据所述至少一个WUS配置信息，确定发送上行唤醒信号的目标功率参考源和/或上行唤醒信号的发送功率。
在本申请实施例中，目标功率参考源是指终端在确定上行WUS的发送功率时，所参考的参考信号的来源，例如，终端可以参考目标功率参考源的参考信号确定上行WUS的发送功率。例如，终端可以根据目标功率参考源的参考信号的发送功率和/或接收功率等，确定上行WUS的发送功率。其中，目标功率参考源可以为终端的服务小区，也可以为节能小区。
通过本申请实施例提供的技术方案，终端获取至少一个WUS配置信息，根据所述至少一个WUS配置信息，确定发送上行WUS的目标功率参考源和/或上行唤醒信号的发送功率，从而可以在需要发送上行WUS时，确定发送上行WUS的功率参考源和/或上行唤醒信号的发送功率，进而实现上行WUS的发送，通过发送上行WUS唤醒节能小区，节省网络侧设备的功耗。
在本申请实施例的一个可能的实现方式中，所述WUS配置信息可以包括但不限于以下至少之一：
(1)功率参考源信息，用于指示确定唤醒信号的功率参考源。终端通过功率参考源信息，可以确定发送WUS的功率参考源。
可选地，功率参考源信息可以为缺省参考源。例如，在缺省的情况下，所述功率参考源可以是服务小区、节能小区、节能小区的关联小区、全球导航卫星系统(Global Navigation Satellite System，GNSS)系统(如全球定位系统(Global Positioning System，GPS))、其它UE、或没有参考源，具体可以根据实际应用确定。
(2)功率参考源的优先级信息；该优先级信息用于指示对应的功率参考源的优先级。当终端有多个可用的功率参考源时，终端可以根据各个功率参考源的优先级，确定使用功率参考源。
可选地，服务小区或节能小区对应的功率参考源的优先级可以为缺省值。例如，可以 预先约定服务小区或节能小区对应的功率参考源的优先级。
(3)第一阈值，用于指示在目标功率参考源的参考信号的接收功率低于或等于所述第一阈值的情况下，调整唤醒信号的目标功率参考源。通过第一阈值，可以指示UE在当前发送WUS使用的功率参考源的接收功率(例如，参考信号接收功率(Reference Signal Receiving Power，RSRP))低于或等于第一阈值时，调整WUS的目标功率参考源，例如，将发送WUS使用的功率参考源更换为参考信号接收功率更高的功率参考源。
(4)第二阈值，用于指示在目标功率参考源的参考信号的接收质量低于或等于所述第二阈值的情况下，调整唤醒信号的目标功率参考源。通过第二阈值，可以指示UE在当前发送WUS使用的功率参考源的接收质量(例如，参考信号接收质量(Reference Signal Receiving Quality，RSRQ))低于或等于第二阈值时，调整WUS的目标功率参考源，例如，将发送WUS使用的功率参考源更换为参考信号接收质量更高的功率参考源。
(5)服务小区参考信号的第二发送功率；通过服务小区参考信号的第二发送功率，在终端以服务小区为发送WUS的功率参考源时，可以根据服务小区参考信号的第二发送功率，确定发送WUS的第一发送功率。
(6)服务小区与节能小区之间的路损；通过服务小区与节能小区之间的路损，在终端以服务小区为发送WUS的功率参考源时，可以根据服务小区与节能小区之间的路损，确定发送WUS的第一发送功率。
(7)节能小区对唤醒信号的第一目标接收功率；通过节能小区对唤醒信号的第一目标接收功率，使得在终端发送WUS前，可以根据节能小区对唤醒信号的第一目标接收功率，确定发送WUS的第一发送功率。
(8)唤醒信号的初始功率修正系数；通过唤醒信号的初始功率修正系数，使得终端在确定发送WUS的第一发送功率时，可以对确定出的第一发送功率进行修正。
(9)服务小区的第二目标接收功率；通过服务小区的第二目标接收功率，在终端以服务小区为发送WUS的功率参考源时，可以根据服务小区的第二目标接收功率，确定发送WUS的第一发送功率。
(10)唤醒信号的最大发送功率；通过唤醒信号的最大发送功率，终端可以控制发送WUS的第一发送功率的最大值，从而使得终端发送WUS的第一发送功率不会超过唤醒信号的最大发送功率。
(11)唤醒信号的发送功率调整步长。通过唤醒信号的发送功率调整步长，终端在发送WUS时，可以将发送WUS的第一发送功率按照所述发送功率调整步长递增，以保证网络侧设备能够接收到终端发送的WUS。
在本申请实施例中，终端可以根据上述WUS配置信息中包括的一项或多项信息确定 上行WUS的目标功率参考源。
例如，所述至少一个WUS配置信息中包括一个功率参考源信息的情况下，终端确定上行WUS的目标功率参考源为所述功率参考源信息指示的功率参考源。
在一个可能的实现方式，终端根据所述至少一个WUS配置信息，确定发送所述上行唤醒信号的目标功率参考源包括以下至少之一：
(1)所述终端确定多个所述功率参考源中的第一功率参考源为所述目标功率参考源，其中，所述至少一个WUS配置信息中为所述第一功率参考源配置了对应的WUS配置。
例如，网络侧设备为终端配置的或协议约定的至少一个WUS配置信息中为第一功率参考源配置了对应的WUS配置。其中，所述WUS配置可以包括WUS的时频域信息、WUS的周期、WUS的信号特征、WUS的最大发送次数、WUS的生效区域等信息中的一项或多项。
又例如，网络侧设备为配置第一功率参考源的小区配置中包含所述至少一个WUS配置信息。
又例如，网络侧设备为终端配置的或协议约定的至少一个WUS配置信息中指示的功率参考源包含第一功率参考源，或网络侧设备为终端配置的或协议约定的至少一个WUS配置信息中的小区信息指示为第一功率参考源。
举例来说，小区1是UE的服务小区，服务小区为UE配置的WUS配置信息指示小区2是一个功率参考源(即有一个WUS配置信息里指示小区2是一个可选的功率参考源，或者说小区2的小区配置(CellConfig)里包含WUS配置信息(WUS Config))，但是没有配置小区3是一个功率参考源(即没有任何一个WUS配置信息里指示小区3是一个可选的功率参考源，或者说小区3的CellConfig里不包含WUS Config)。则在UE检测到小区3的同步信号块(Synchronization Signal Block，SSB)，UE实际是不能将小区3作为功率参考源，并利用小区3的SSB调整WUS发送功率的。因为小区3可能就是简单的一个正常工作的小区，跟任何节能小区都没有关系，即小区3并不是节能小区的关联小区。
(2)所述终端确定多个功率参考源中优先级最高的功率参考源为所述目标功率参考源，其中，所述多个功率参考源为所述至少一个WUS配置信息中的功率参考源信息对应的功率参考源。
例如，所述至少一个WUS配置信息中配置了多个功率参考源及其优先级，多个功率参考源包括服务小区和节能小区，且节能小区的功率参考源优先级比服务小区高，UE可以将其中优先级最高的功率参考源(例如，节能小区)作为目标功率参考源。
(3)所述终端选择所述多个功率参考源中的第二功率参考源作为目标功率参考源，其中，所述终端能够检测到所述第二功率参考源发送的测量参考信号。
也就是说，终端使用能检测到其发送的测量参考信号的第二功率参考源作为目标功率参考源。采用该可能的实现方式，终端可以根据测量第二功率参考源发送的测量参考信号的测量结果，确定发送WUS的功率。
在该可能的实现方式中，测量参考信号包括但不限于SSB、信道状态信息(Channel state information，CSI)参考信号(Reference Signal，RS)或专用RS。
(4)所述终端根据终端实现从多个所述功率参考源中选择所述目标功率参考源。
也就是说，可以由终端实现决定目标功率参考源。例如，终端可以根据本地设置或本地策略，从多个所述功率参考源中选择所述目标功率参考源。
(5)所述终端选择所述多个功率参考源中的第三功率参考源作为目标功率参考源，其中，所述第三功率参考源为参考信号的信号强度最强的功率参考源或参考信号的信号质量最强的功率参考源。
其中，终端可以采用上述(1)至(5)中的之一确定目标功率参考源，也可以组合其中的两者或三者或全部确定目标功率参考源。
例如，网络侧设备为UE配置了多个WUS功率参考源及其优先级，功率参考源包括服务小区和节能小区，且节能小区的功率参考源优先级比服务小区高。若UE准备发送WUS的时候，可以同时检测到来自服务小区的SSB/RS和节能小区的SSB/RS，则UE可以使用优先级最高的功率参考源，即节能小区作为WUS功率参考源。若UE仅能检测到服务小区的SSB/RS，即便节能小区的WUS功率参考源优先级比服务小区高，UE也没办法使用节能小区作为WUS功率参考源，这时只能把服务小区作为WUS功率参考源。由此可见，此例子结合了上述(1)至(3)中的实现方式。
又如，网络侧设备仅为UE配置了节能小区作为UE发送WUS的功率参考源。若UE准备发送WUS的时候，仅能检测到服务小区的SSB/RS，UE也没办法使用节能小区作为WUS功率参考源。此时，若网络侧设备为UE配置了发送WUS的缺省初始功率，UE可以基于实现决定是使用所述缺省初始功率发送WUS，还是等待UE接收到节能小区的SSB/RS之后再确定UE发送WUS的功率。由此可见，此例子结合了上述(1)、(3)和(4)。
在一个可能的实现方式中，如图3所示，S220可以包括S221和S222，即终端可以在确定发送上行唤醒信号的目标功率参考源之后，根据所述目标功率参考源，确定所述上行唤醒信号的发送功率。
例如，终端可以根据测量目标功率参考源发送的参考信号得到的接收功率，确定上行 WUS的发送功率。
或者，在另一个可能的实现方式中，终端也可以直接将服务小区为上行WUS的目标功率参考源，根据所述第一WUS配置信息确定上行WUS的发送功率。
可选的，终端可以按照以下之一的方式确定上行WUS的初始发送功率：
(1)Ptx-init＝Ptarget-ES+Ppathloss-2+Prx-Ptx，其中，Ptarget-ES为节能小区对唤醒信号的第一目标接收功率，Ppathloss-2为服务小区与节能小区之间的路损，Ptx为服务小区参考信号的第二发送功率，Prx为所述终端测量服务小区的参考信号得到的接收功率，Ptx-init为上行WUS的初始发送功率。
在该可能的实施方式中，服务小区参考信号的第二发送功率Ptx，节能小区对唤醒信号的第一目标接收功率Ptarget-ES以及服务小区与节能小区之间的路损Ppathloss-2可以是终端从网络侧设备接收或从协议约定的方式确定的，例如，这些参数可以包括在WUS配置信息中。
服务小区向终端发送测量参考信号，例如SSB、CSI-RS或专用RS，终端通过测量服务小区发送的测量参考信号，得到接收功率Prx，则可以得到服务小区到UE的路损为：
Ppathloss-1＝Ptx-Prx
若服务小区将服务小区和节能小区之间空口路损Ppathloss-2和节能小区对WUS的第一目标接收功率Ptarget-ES和服务小区参考信号发送功率Ptx配置给UE，则UE发送WUS的初始功率Ptx-init为：
Ptx-init＝Ptarget-ES+(Ppathloss-2-Ppathloss-1＝Ptarget-ES+Ppathloss-2+Prx-Ptx。
通过该可能的实施方式，可以根据服务小区参考信号的第二发送功率、节能小区对唤醒信号的第一目标接收功率以及终端测量服务小区的测量参考信号得到接收功率，确定发送上行WUS的初始功率，以保证终端发送的上行WUS能够被节能小区所接收。
(2)Ptx-init＝Ptarget-ES+Ppathloss-2+Prx-Ptx+PΔ，其中，PΔ为唤醒信号的初始功率修正系数。
在该可能的实现方式中，如果UE从网络侧设备接收或从协议约定的方式，确定以下参数：
WUS初始功率修正系数PΔ；
在上述(1)的基础上，若UE考虑到功率修正系数，则UE发送上行WUS的初始功率Ptx-init为：
Ptx-init＝Ptarget-ES+Ppathloss-2+Prx-Ptx+PΔ。
通过该可能的实施方式，可以对实施方式(1)确定的初始发送功率进行修正，以进一步使得终端以该初始发送功率发送的WUS能够被节能小区所接收。
对于上述实施方式(1)和(2)，可选的，若Ppathloss-1＞Ppathloss-2，则UE不使用服务小区作为WUS的功率参考源。也就是说，在服务小区到UE的路损大于服务小区与节能小区之间的路损的情况下，则服务小区不适合作为上行WUS的目标功率参考源，因此，UE不使用服务小区作为WUS的功率参考源。
(3)Ptx-init＝Ptarget-Serv+Ptx-Prx，其中，Ptarget-Serv为服务小区的目标接收功率。
在该可能的实现方式中，UE从网络侧设备接收或从协议约定的方式，确定以下参数：
-服务小区参考信号的第二发送功率Ptx；
-服务小区的第二目标接收功率Ptarget-Serv；
例如，上述WUS配置信息中可以包括上述参数。
若服务小区向终端发送测量参考信号，如SSB、CSI-RS或专用RS。测量参考信号的功率Ptx为协议约定的或网络侧设备通过WUS配置信息告知UE。UE测量接收到的测量参考信号，确定接收功率为Prx，则服务小区到UE的路损为：
Ppathloss-1＝Ptx-Prx；
则UE发送WUS的初始功率Ptx-init为：
Ptx-init＝Ptarget-Serv+Ppathloss-1＝Ptarget-Serv+Ptx-Prx。
通过该可能的实施方式，可以根据服务小区的第二目标接收功率和服务小区参考信号的发送功率，确定发送WUS的初始发送功率，以使得UE初始发送的WUS能够被节能小区所接收。
(4)Ptx-init＝Ptarget-Serv+Ptx-Prx+PΔ。
通过该可能的实施方式，可以对实施方式(3)确定的初始发送功率进行修正，以进一步使得终端以该初始发送功率发送的WUS能够被节能小区所接收。
(5)P′tx-init＝min(Ptx-wusMax，Ptx-init)，其中，Ptx-wusMax为唤醒信号的最大发送功率，P′tx-init为最后确定的上行WUS的初始发送功率。
在实施方式(1)至(4)的基础上，UE从网络侧设备接收或从协议约定的方式，确定以下参数：
WUS的最大发送功率Ptx-wusMax；
例如，上述WUS配置信息中可以包括WUS的最大发送功率Ptx-wusMax。
UE通过上述实施方式(1)至(4)中任一种实施方式确定Ptx-init，若UE考虑到WUS的最大发送功率，则UE发送上行WUS的初始发送功率Ptx-init为：
P′tx-init＝min(Ptx-wusMax，Ptx-init)
通过该可能的实施方式，可以保证上行WUS的初始发送功率不会超过WUS的最大 发送功率。
在一个可能的实现方式中，所述终端根据所述至少一个WUS配置信息，确定所述上行唤醒信号的发送功率，还可以包括：在确定所述上行唤醒信号的初始发送功率之后，所述终端可以按照所述唤醒信号的发送功率调整步长，调整所述上行唤醒信号的发送功率，直至所述上行唤醒信号的发送功率达到所述最大发送功率。
例如，UE从网络侧设备接收或从协议约定的方式，确定以下参数：
WUS的发送功率调整步长Pramping；
UE第一次发送上行WUS的时候，以初始发送功率Ptx-init或P′tx-init发送上行WUS。若此后UE仍需发送上行WUS，则可以使用WUS的发送功率调整步长Pramping逐步抬升功率，例如，第二次发送WUS的功率就变成Ptx-init+Pramping或P′tx-init+Pramping，以此类推，直到UE发送WUS的功率达到WUS最大发送功率，或UE停止发送WUS。
通过上述可能的实现方式，通过以发送功率调整步长Pramping逐步抬升发送上行WUS的发送功率，可以进一步确保节能小区能够接收到UE发送的上行WUS。
其中，上述实施方式(1)确定上行WUS的初始发送功率的理论原理如图4所示，若UE在服务小区(servingCell)和节能小区(Energy Saving-Cell，ES-Cell)在空间上连接的直线上，则UE通过可以计算出UE和节能小区(ES-Cell)之间的路损Ppathloss-3为：
Ppathloss-3＝Ppathloss-2-Ppathloss-1
该Ppathloss-3是UE和ES-Cell之间理论上的最大路损，也就是说，使用Ppathloss-3所确定的UE发送上行WUS的初始功率实际上是UE发送上行WUS理论上所需的最大功率。
具体来说，若UE不在服务小区(servingCell)和节能小区(ES-Cell)在空间上连接的直线上，UE通过Ppathloss-2-Ppathloss-1计算出来的UE和节能小区(ES-Cell)之间的路损P′pathloss-3实际上是比上述Ppathloss-3要小的，从而可能会导致UE确定WUS的初始发送功率时偏小。UE可以通过上述实施方式(2)进行优化，也可以通过以唤醒信号的发送功率调整步长逐步抬升上行WUS的发送功率解决初始发送功率时偏小的问题。
终端在最开始需要发送上行WUS时，可以通过上述各个可能的实现方式确定WUS的目标功率参考源，然而终端在移动的过程中，原来可用的WUS功率参考源可能变得不可用，需要调整WUS功率参考源。例如，原来UE的WUS的功率参考源只有服务小区，但UE在移动过程中逐渐远离服务小区，接近节能小区，这时候WUS的功率参考源可能会发生多种变化，例如：变成服务小区和节能小区都可作为WUS功率参考源、变成只有节能小区可以作为WUS功率参考源、或者变成只有GNSS系统可以作为WUS功率参考源等，因此，在一个可能的实现方式中，如图5所示，在S220之后，该方法还可以包括以下步骤：
S230，所述终端根据所述WUS配置信息，调整发送所述上行唤醒信号的目标功率参考源。
在一个可能的实现方式，S230也可以在图3中的S221之后执行，也可以在图3中的S222之后执行。例如，当UE按照第一WUS配置发送上行WUS(举例来说，所述WUS配置可以包含WUS的时频域信息、WUS的周期、WUS的信号特征、WUS的最大发送次数、WUS的生效区域等WUS配置)时，UE可以调整上行WUS的目标功率参考源，然后按照调整后的目标功率参考源，确定上行WUS的发送功率。
在上述可能的实现方式中，可选地，所述终端根据所述至少一个WUS配置信息，调整发送所述上行唤醒信号的目标功率参考源，可以包括：在满足触发条件的情况下，所述终端根据所述至少一个WUS配置信息，调整发送所述上行唤醒信号的目标功率参考源。也就是说，在该可能的实现方式中，在满足一定的触发条件的情况下，终端再调整上行WUS的目标功率参考源。
可选地，所述触发条件包括但不限于以下至少之一：
(1)所述终端与所述目标功率参考源发生失步。也就是说，在终端与当前WUS的目标功率参考源的同步状态变为失步时，终端可以调整WUS的目标功率参考源。
(2)所述终端测量所述目标功率参考源的参考信号得到的接收功率低于或等于所述第一阈值。在终端测量当前WUS的目标功率参考源的参考信号得到接收功率(例如，RSRP)低于或等于第一阈值的情况下，终端与当前WUS的目标功率参考源之间的路损较大，则需要调整WUS的目标功率参考源。
(3)所述终端测量所述目标功率参考源的参考信号得到的接收质量低于或等于所述第二阈值。在终端测量当前WUS的目标功率参考源的参考信号得到接收质量(例如，RSRQ)低于或等于第二阈值的情况下，终端与当前WUS的目标功率参考源之间的路损较大，则终端调整WUS的目标功率参考源。
(4)所述终端接收到重配置消息，其中，所述重配置消息中的WUS配置信息未包含所述目标功率参考源。在终端接收的重配置消息中重配置的WUS配置信息中未包含当前WUS的目标功率参考源，则指示网络侧设备不推荐终端使用当前WUS的目标功率参考源，则终端调整WUS的目标功率参考源。其中，该重配置消息可以为RRC重配置消息。
(5)所述终端接收到服务小区的系统消息，其中，所述系统消息中的WUS配置信息未包含所述目标功率参考源。在终端接收的系统消息中配置的WUS配置信息中未包含当前WUS的目标功率参考源，则指示网络侧设备不推荐终端使用当前WUS的目标功率参考源，则终端调整WUS的目标功率参考源。
(6)所述终端检测到优先级高于所述目标功率参考源的功率参考源的测量参考信号。在UE检测到优先级更高的功率参考源的SSB或RS(如CSI-RS或专用RS)的情况下，UE可以调整当前WUS的目标功率参考源，例如，调整为优先级更高的功率参考源。
(7)所述终端离开第一WUS配置信息的生效区域，其中，所述第一WUS配置信息为所述至少一个WUS配置信息中包括所述目标功率参考源的WUS配置信息。在UE离开当前WUS的目标功率参考源对应的WUS配置信息的生效区域的情况下，UE需要调整WUS的目标功率参考源，以选择更合适的功率参考源发送上行WUS。
(8)所述终端发送上行唤醒信息的次数达到所述第一WUS配置信息所确定的唤醒信号的最大发送次数。例如，第一WUS配置信息中可以包括WUS配置，该WUS配置中包括WUS的最大发送次数，如果终端使用第一WUS配置信息配置的功率参考源作为WUS的目标功率参考源发送WUS的次数超过该最大发送次数，则说明以该功率参考源作为WUS的目标功率参考源不合适，不能被节能小区成功接收，因此，终端调整WUS的目标功率参考源。
在一个可能的实现方式中，与终端确定上行WUS的目标功率参考源相似，所述终端根据所述至少一个WUS配置信息，调整发送所述上行唤醒信号的目标功率参考源，可以包括以下至少之一的实施方式：
(1)所述终端将所述目标功率参考源调整为第一功率参考源，其中，所述第一功率参考源为配置了对应的WUS配置信息的功率参考源；
(2)所述终端将所述目标功率参考源调整为所述多个功率参考源中优先级最高的功率参考源；
(3)所述终端将所述目标功率参考源调整为所述多个所述功率参考源中的第二功率参考源，其中，所述终端能够检测到所述第二功率参考源发送的测量参考信号；
(4)所述终端按照终端实现调整所述目标功率参考源；
(5)所述终端将所述目标功率参考源调整为所述多个功率参考源中的第三功率参考源，其中，所述第三功率参考源为参考信号的信号强度最强的功率参考源或参考信号的信号质量最强的功率参考源。
与终端确定上行WUS的目标功率参考源相似，终端可以按照以上之一的实施方式调整上行WUS的目标功率参考源，也可以按照以上至少之一的实施方式的组合调整上行WUS的目标功率参考源，具体可以参见上述关于终端确定上行WUS的目标功率参考源的描述，在此不再赘述。
通过本申请实施例提供的技术方案，终端可以确定发送用于唤醒节能小区的上行WUS的发送功率，以保证终端发送的上行WUS能够被节能小区所检测到。
基于本申请实施例的同一技术构思，本申请实施例还提供了一种唤醒信号的配置方法，该方法可以由网络侧设备执行，换言之，所述方法可以由安装在网络侧设备上的软件或硬件来执行。如图6所示，该方法600可以包括以下步骤。
S610，网络侧设备获取终端的至少一个WUS配置信息，其中，所述WUS配置信息用于确定终端发送上行WUS的功率参考源和/或上行唤醒信号的发送功率；
S620，网络侧设备向所述终端发送所述至少一个WUS配置信息。
其中，所述至少一个WUS配置信息与方法200中的所述至少一个WUS配置信息相同，具体可以参见方法200中的相关描述，在此不再赘述。
在一个可能的实现方式中，所述WUS配置信息包括但不限于以下至少之一：
(1)功率参考源信息，用于指示确定唤醒信号的功率参考源；
(2)功率参考源的优先级信息；
(3)第一阈值，用于指示在目标功率参考源的参考信号的接收功率低于或等于所述第一阈值的情况下，调整唤醒信号的目标功率参考源；
(4)第二阈值，用于指示在目标功率参考源的参考信号的接收质量低于或等于所述第二阈值的情况下，调整唤醒信号的目标功率参考源；
(5)服务小区参考信号的第二发送功率；
(6)服务小区与节能小区之间的路损；
(7)节能小区对唤醒信号的第一目标接收功率；
(8)唤醒信号的初始功率修正系数；
(9)服务小区的第二目标接收功率；
(10)唤醒信号的最大发送功率；
