具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
诸如AR(Augmented Reality，增强现实)/VR(Virtual Reality，虚拟现实)、车车通信等新型互联网应用的不断涌现对无线通信技术提出了更高的要求，驱使无线通信技术不断进行演进以满足应用的需求。目前，蜂窝移动通信技术正在处于新一代技术的演进阶段。这里所说的新一代技术的一个重要特点就是支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求，如eMBB(enhanced Mobile Broad Band，增强移动宽带)业务类型主要 的要求侧重在大带宽，高速率等方面；URLLC(Ultra Reliable Low Latency Communication，超高可靠超低时延通信)业务类型主要的要求侧重在较高的可靠性以及低的时延方面；mMTC(massive Machine Type Communication，大型机器类通信)业务类型主要的要求侧重在大的连接数方面。因此，新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
对于LTE系统中的动态调度来说，一个调度信令只能指示一个时频资源，该时频资源用于指示时域单元中的频域资源。这里所说的时域单元是时间上的单位，可以是符号、子帧、时隙、无线帧等通信系统中常用的时域单元。请参考图1，其示出了LTE系统中的资源调度方法的示意图。图1中以时域单元为子帧，且一个阴影区域和一个白色填充区域组成一个子帧为例进行说明，其中，阴影区域是下行控制区域，用于传输控制信令，这里的控制信令包括调度信令，以指示UE在其箭头所指示的一个时频资源上进行数据传输；白色填充区域是下行数据区域，即调度信令的箭头所指示的时频资源，用于供UE进行数据传输。
UE的续航能力是一个影响UE性能的重要指标。由于UE需要持续检测是否接收到信令，虽然在UE不需要进行业务交互时，基站并没有信令发送给UE，但是，UE仍然需要检测是否接收到信令，导致UE的能耗较多，所以，LTE系统中定义了休眠态，当UE不需要进行业务交互时进入休眠态，以避免对信令的检测，降低UE的能耗。
当UE处于休眠态时，UE可以基于基站的配置，周期性地监听PDCCH(Physical Downlink Control Channel，物理下行控制信道)。可选的，UE可以在寻呼时刻(PO)时刻监听PDCCH；如果接收到下行控制信令中具有UE的寻呼消息的指示，则进入到激活状态，以进行数据传输；如果接收到的下行控制信令中没有UE的寻呼消息的指示，则继续进入休眠态，并周期性重新监听PDCCH，以节省UE的能耗，请参考图2。和/或，基站可以在发送寻呼消息之前发送唤醒信号，该唤醒信号中携带有是否具有UE的寻呼消息的指示。UE可以周期性监听是否接收到唤醒信号，如果接收到唤醒信号中具有UE的寻呼消息的指示，则进入到激活状态，以进行数据传输；如果接收到的唤醒信号中没有UE的寻呼消息的指示，则继续进入休眠态，并周期性重新监听唤醒信号， 以节省UE的能耗，请参考图3。
虽然通过监听PDCCH和/或唤醒信号的方法可以节省UE的能耗，但是基站为UE配置了多个载波的情况下，终端需要在每个载波上进行唤醒信息的检测，这也会导致UE的能耗较大。其中，唤醒信息包括下行控制信令和/或唤醒信号。
这里所说的载波是用于承载数据传输的无线资源，该无线资源可以是载波，也可以是载波上的带宽部分，还可以是两者的结合，或是其他定义的无线资源块，本实施例不作限定。
本实施例中，可以通过一条唤醒信息指示UE进行载波激活。其中，载波激活指的是UE激活被指示的载波上的数据传输和/或信令检测行为，被指示的载波是基站预先配置给UE的，可以处于激活或是非激活的状态。也即，可以通过一条唤醒信息指示UE激活在至少两个载波上的数据传输和/或信令检测行为，从而解决了UE需要在每个载波上检测唤醒信息的问题，达到了节省UE的能耗，提高UE的续航能力的效果。
下面将对本公开实施例提供的载波激活方法所涉及到的实施环境进行简要的说明。
图4为本公开实施例提供的载波激活方法所涉及到的实施环境的示意图，如图1所示，该实施环境可以包括UE401和至少一个基站402(图4中仅示出了一个基站402)，其中，基站402可以在预定载波上向UE401发送唤醒信息，UE401根据该唤醒信息激活载波。
图5是根据一示例性实施例示出的一种载波激活方法的流程图，该载波激活方法应用于图4所示的实施环境中，如图5所示，该载波激活方法包括以下步骤。
在步骤501中，基站生成唤醒信息。
在步骤502中，基站在预定载波上向UE发送该唤醒信息，该预定载波是分配给UE的至少两个载波中被配置了传输唤醒信息的载波。
在步骤503中，UE在预定载波上接收唤醒信息。
在步骤504中，UE根据唤醒信息激活预定载波和至少一个其他载波，或，UE根据唤醒信息激活至少两个其他载波，该其他载波是至少两个载波中除预 定载波之外的载波。
其中，步骤501-502可以单独实现成为基站侧的实施例，步骤503-504可以单独实现成为UE侧的实施例。
综上所述，本公开提供的载波激活方法，在预定载波上接收唤醒信息，根据该唤醒信息激活预定载波和至少一个其他载波，或，根据唤醒信息激活至少两个其他载波，由于可以通过一条唤醒信息指示UE激活至少两个载波，从而解决了UE需要在每个载波上检测唤醒信息，根据唤醒信息确定是否需要激活该载波的问题，达到了节省UE的能耗，提高UE的续航能力的效果。
本公开中，UE激活载波的实现方式有四种，下面分别以四个实施例对这四种实现方式进行详细说明。
图6是根据另一示例性实施例示出的一种载波激活方法的流程图，该载波激活方法应用于图4所示的实施环境中，如图6所示，该载波激活方法包括如下步骤。
在步骤601中，基站生成携带有序列的唤醒信号，该序列用于指示UE激活预定载波和至少一个其他载波，或，该序列用于指示UE激活至少两个预定载波。
在实现本步骤之前，基站可以先为UE配置至少两个载波，再从该至少两个载波中指定一个载波传输唤醒信号，该被基站指定的载波称为预定载波。
其他载波是相对于预定载波来说的，即其他载波可以是为UE分配的至少两个载波中除预定载波之外的载波。假设基站为UE分配的载波包括载波1、2、3、4，且预定载波是1，则其他载波可以是载波2、3、4中的一种或两种或全部三种。
在实现本步骤时，基站可以从为UE分配的至少两个载波中确定待激活的载波，再根据待激活的载波生成携带有序列的唤醒信号。其中，在一种实现方式中，该唤醒信号除了可以指示UE激活预定载波，还可以指示UE激活至少一个其他载波；在另一种实现方式中，该唤醒信息可以指示UE激活至少两个其他载波。
本实施例提供了三种序列，下面分别对这三种序列进行说明。
1)在第一种实现方式中，该序列包括至少两个指示位，每个指示位用于指示一个载波，且数值为预定数值的各个指示位所指示的载波为待激活的载 波，待激活的载波中包括预定载波和至少一个其他载波，或，待激活的载波中包括至少两个其他载波。
其中，序列中指示位的位数可以等于基站为该UE分配的载波的个数，比如，基站为UE分配了4个载波，则该序列包括4个指示位。或者，序列中指示位的位数还可以等于基站为其它UE分配的载波的个数，且该个数大于基站为UE分配的载波的个数。比如，基站为UE分配了4个载波，为其它UE分配了8个载波，则该序列包括8个指示位，且其中有4个指示位是预留的。
基站可以预先获取指示位与载波标识的第一对应关系，在确定待激活的载波后，在该第一对应关系中查找各个载波标识所对应的指示位，将该指示位的数值设置为预定数值；将剩余指示位的数值设置为除预定数值以外的数值。
比如，序列包括4个指示位，根据第一对应关系确定该4个指示位由前到后依次指示载波1-4，假设待激活的载波是载波1和2，且预定数值是1，除预定数值以外的数值是0，则基站生成的序列可以为1100。
需要说明的第一点是，第一对应关系可以由基站发送给UE，也可以在通信协议中指定，本实施例不作限定。
需要说明的第二点是，预定数值和除预定数值以外的数值可以由基站通知UE，也可以在通信协议中指定，本实施例不作限定。
需要说明的第三点时，不同UE的唤醒信号中的序列可以相同，也可以不同，本实施例不作限定。
2)在第二种实现方式中，该序列用于指示一个第一载波集合，该第一载波集合中的各个载波是待激活的载波，待激活的载波中包括预定载波和至少一个其他载波，或，待激活的载波中包括至少两个其他载波。
基站可以预先获取序列与第一载波集合的第二对应关系，在确定待激活的载波后，先确定该待激活的载波所对应的第一载波集合，再在第二对应关系中查找该第一载波集合对应的序列。其中，待激活的载波所对应的第一载波集合是指第一载波集合中的载波与待激活的载波完全相同。比如，待激活的载波为载波1、2，则第一载波集合中只包括载波1、2；待激活的载波为载波2、3，则第一载波集合中只包括载波2、3。
在实现时，第一载波集合中包括多个载波是指第一载波集合中包括多个载波的载波标识，由于每个载波标识用于标识一个载波，也就相当于第一载波集合包括多个载波。
比如，第二对应关系中序列1所指示的第一载波集合包括载波1-4，序列2所指示的第一载波集合包括载波5-8，假设待激活的载波是载波1-4，则基站生成的序列为序列1。
需要说明的是，第二对应关系可以由基站发送给UE，也可以在通信协议中指定，本实施例不作限定。
3)在第三种实现方式中，每个序列用于指示一个待激活的载波，待激活的载波中包括预定载波和至少一个其他载波，或，待激活的载波中包括至少两个其他载波。
唤醒信号中包括至少两个序列，且每个序列用于指示一个待激活的载波。可选的，这里所说的序列之间满足正交关系，以保证序列检测的准确性。
基站可以预先获取序列与载波标识的第三对应关系，在确定待激活的载波后，在该第三对应关系中查找各个载波标识所对应的序列。
比如，第三对应关系中序列1指示载波1，序列2指示载波2，序列3指示载波3，序列4指示载波4，假设待激活的载波是载波2和3，则基站生成的序列包括序列2和3。
需要说明的是，第三对应关系可以由基站发送给UE，也可以在通信协议中指定，本实施例不作限定。
在步骤602中，基站在预定载波上向UE发送该唤醒信号，该预定载波是分配给UE的至少两个载波中被配置了传输唤醒信号的载波。
基站确定预先配置的预定载波，在该预定载波上向UE发送唤醒信号。
在步骤603中，UE在预定载波上接收唤醒信号。
在步骤604中，UE读取唤醒信号中的序列；根据序列激活预定载波和至少一个其他载波，或，根据序列激活至少两个其他载波，该其他载波是至少两个载波中除预定载波之外的载波。
对应于上述三种序列，UE可以采用以下三种方式激活载波。
1)当序列由基站通过第一种实现方式生成时，UE可以确定数值为预定数值的各个指示位，再在第一对应关系中查找各个指示位所指示的载波标识，再激活各个载波标识所指示的载波。
2)当序列由基站通过第二种实现方式生成时，UE可以在第二对应关系中查找该序列所指示的第一载波集合，再激活该第一载波集合中的各个载波。
3)当序列由基站通过第三种实现方式生成时，UE可以在第三对应关系中 查找每个序列所指示的载波标识，再激活各个载波标识所指示的载波。
其中，步骤601-602可以单独实现成为基站侧的实施例，步骤603-604可以单独实现成为UE侧的实施例。
综上所述，本公开提供的载波激活方法，在预定载波上接收唤醒信息，根据该唤醒信息激活预定载波和至少一个其他载波，或，根据唤醒信息激活至少两个其他载波，由于可以通过一条唤醒信息指示UE激活至少两个载波，从而解决了UE需要在每个载波上检测唤醒信息，根据唤醒信息确定是否需要激活该载波的问题，达到了节省UE的能耗，提高UE的续航能力的效果。
图7是根据另一示例性实施例示出的一种载波激活方法的流程图，该载波激活方法应用于图4所示的实施环境中，如图7所示，该载波激活方法包括如下步骤。
在步骤701中，基站生成携带有指示信息的下行控制信令，该指示信息用于指示UE激活预定载波和至少一个其他载波，或，该指示信息用于指示UE激活至少两个其他载波。
其中，载波、预定载波、其他载波的解释详见步骤601中的描述。
在实现本步骤时，基站可以从为UE分配的至少两个载波中确定待激活的载波，再根据待激活的载波生成携带有指示信息的下行控制信令。其中，在一种实现方式中，该下行控制信令除了可以指示UE激活预定载波，还可以指示UE激活至少一个其他载波；在另一种实现方式中，该下行控制信令可以指示UE激活至少两个其他载波。
需要说明的是，这里所说的指示信息可以理解为图6所示的实施例中的序列，则指示信息的生成过程详见步骤601中的描述。
下面对基站将指示信息添加到下行控制信令中的添加方式进行介绍。
在第一种添加方式中，当指示信息在下行控制信令中的位置固定时，将指示信息添加到下行控制信令中固定的位置处。
指示信息在下行控制信令中的位置固定包括两种情况：第一种情况是指示信息的位数固定，此时，指示信息在下行控制信令中的起始位置和结束位置均固定；第二种情况是指示信息的位数不固定，此时，可以是指示信息在下行控制信令中的起始位置固定，结束位置不固定，也可以是指示信息在下行控制信令中的结束位置固定，起始位置不固定，本实施例不作限定。
若指示信息的位数固定，且其在下行控制信令中的位置固定，则可以在通信协议中指定位置信息；也可以在基站第一次向UE发送下行控制信令之前指示位置信息，UE对该位置信息进行存储，后续，基站不需要每次向UE发送下行控制信令之前指示该位置信息；也可以在基站每次向UE发送下行控制信令之前指示该位置信息。其中，位置信息可以包括起始位置和结束位置，或，可以包括起始位置和位数，或，可以包括结束位置和位数。
若指示信息的位数不固定，且其在下行控制信令中的位置固定，则可以在通信协议中指定该起始位置或结束位置，基站还需要在每次发送的下行控制信令之前指示该指示信息的位数；或者，也可以在基站第一次向UE发送下行控制信令之前指示该起始位置或结束位置，基站还需要在每次发送的下行控制信令中指示该指示信息的位数；或者，基站可以在每次发送的下行控制信令之前指示该指示信息的起始位置和结束位置。
以指示信息的位数固定，且其在下行控制信令中的位置固定为例，假设指示信息在下行控制信令中的起始位置是第5比特，位数是2，则基站可以将该指示信息的数值添加到下行控制信令中第5-6比特的位置处。
在第二种添加方式中，当指示信息在下行控制信令中的位置不固定时，生成位置信息，该位置信息用于指示本次指示信息在下行控制信令中的位置，将指示信息添加到下行控制信令中位置信息所指示的位置处。
指示信息在下行控制信令中的位置不固定包括两种情况：第一种情况是指示信息的位数固定，此时，可以根据指示信息在下行控制信令中的起始位置推断出结束位置，或者，可以根据指示信息在下行控制信令中的结束位置推断出起始位置。第二种情况是指示信息的位数不固定，此时，指示信息在下行控制信令中的起始位置和结束位置均不固定。
若指示信息的位数固定，且其在下行控制信令中的位置不固定，则可以在通信协议中指定该位数，也可以在基站第一次向UE发送下行控制信令之前指示该位数。此后，基站需要在每次发送的下行控制信令中指示该起始位置和/或结束位置。
若指示信息的位数不固定，且其在下行控制信令中的位置不固定，则基站需要在每次发送下行控制信令之前指示该起始位置和结束位置，或者，基站需要在每次发送下行控制信令之前指示该起始位置和位数，或者，基站需要在每次发送下行控制信令之前指示该结束位置和位数。
以指示信息的位数不固定，且其在下行控制信令中的位置不固定为例，假设指示信息为2比特，且基站要将其添加到下行控制信令中的第5-6比特的位置处，则基站可以生成用于指示本次指示信息位于下行控制信令中第5-6比特的位置信息，再将指示信息添加到下行控制信令中的第5-6比特的位置处。
在步骤702中，基站在预定载波上向UE发送该下行控制信令，该预定载波是分配给UE的至少两个载波中被配置了传输下行控制信令的载波。
基站确定预先配置的预定载波，在该预定载波上向UE发送下行控制信令。
在步骤703中，UE在预定载波上接收该下行控制信令。
在步骤704中，UE读取下行控制信令中的指示信息；根据该指示信息激活预定载波和至少一个其他载波，或，根据该指示信息激活至少两个其他载波，该其他载波是至少两个载波中除预定载波之外的载波。
对应于基站将指示信息添加到下行控制信令中的两种添加方式，UE从下行控制信令中获取指示信息也有两种获取方式，下面分别对这两种获取方式进行介绍。本实施例中以下行控制信令为下行控制信令为例，若将指示信息添加到其他下行控制信令中，其获取方式与下面所述的两种获取方式相同，此处不作赘述。
在第一种获取方式中，当指示信息在下行控制信令中的位置固定时，从下行控制信令中固定的位置处读取指示信息。
若指示信息的位数固定，且其在下行控制信令中的位置固定，则UE可以从通信协议中获取指示信息在下行控制信令中的位置信息；也可以在基站第一次发送下行控制信令之前获取该位置信息，UE对该位置信息进行存储，后续，基站不需要每次向UE发送下行控制信令之前指示该位置信息；还可以在基站每次发送下行控制信令之前获取该位置信息。其中，位置信息可以包括起始位置和结束位置，或，可以包括起始位置和位数，或，可以包括结束位置和位数。UE再根据上述位置信息确定指示信息在下行控制信令中的位置，从该位置处读取指示信息。
若指示信息的位数不固定，且其在下行控制信令中的位置固定，则UE可以从通信协议中获取指示信息在下行控制信令中的起始信息，或，可以在基站第一次发送下行控制信令之前获取指示信息的起始位置，再从本次接收到的下行控制信令中获取指示信息的位数；或者，UE可以从通信协议中获取指示信息在下行控制信令中的结束信息，或，可以在基站第一次发送下行控制信令之 前获取指示信息的结束位置，再从本次接收到的下行控制信令中获取指示信息的位数；或者，UE可以在基站每次发送下行控制信令之前获取指示信息的起始位置和结束位置。UE再根据上述信息确定指示信息在下行控制信令中的位置，从该位置处读取指示信息。
以指示信息的位数固定，且其在下行控制信令中的位置固定为例，假设指示信息在下行控制信令中的起始位置是第5比特，位数是2，则UE可以从下行控制信令中第5-6比特的位置处读取指示信息。
在第二种获取方式中，当指示信息在下行控制信令中的位置不固定时，获取位置信息，位置信息用于指示本次指示信息在下行控制信令中的位置；从下行控制信令中位置信息所指示的位置处读取指示信息。
若指示信息的位数固定，且其在下行控制信令中的位置不固定，则UE可以从通信协议中获取指示信息的位数，或，在基站第一次发送下行控制信令之前获取指示信息的位数，再从本次接收到的下行控制信令中获取指示信息的起始位置和/或结束位置，根据上述信息确定指示信息在下行控制信令中的位置，从该位置处读取指示信息。
若指示信息的位数不固定，且其在下行控制信令中的位置不固定，则UE可以在基站每次发送下行控制信令之前获取指示信息的起始位置和结束位置；或者，UE可以在基站每次发送下行控制信令之前获取指示信息的起始位置和位数；或者，UE可以在基站每次发送下行控制信令之前获取指示信息的结束位置和位数。UE再根据上述信息确定指示信息在下行控制信令中的位置，从该位置处读取指示信息。
以指示信息的位数不固定，且其在下行控制信令中的位置不固定为例，假设指示信息为2比特，且位置信息指示该指示信息添加到下行控制信令中的第5-6比特的位置处，则UE根据该位置信息从下行控制信令中第5-6比特处读取指示信息。
在得到指示信息后，若将该指示信息理解为图6所示的实施例中的序列，则根据指示信息激活载波的流程详见步骤604中的描述。
其中，步骤701-702可以单独实现成为基站侧的实施例，步骤703-704可以单独实现成为UE侧的实施例。
综上所述，本公开提供的载波激活方法，在预定载波上接收唤醒信息，根据该唤醒信息激活预定载波和至少一个其他载波，或，根据唤醒信息激活至少 两个其他载波，由于可以通过一条唤醒信息指示UE激活至少两个载波，从而解决了UE需要在每个载波上检测唤醒信息，根据唤醒信息确定是否需要激活该载波的问题，达到了节省UE的能耗，提高UE的续航能力的效果。
图8是根据另一示例性实施例示出的一种载波激活方法的流程图，该载波激活方法应用于图4所示的实施环境中，如图8所示，该载波激活方法包括如下步骤。
在步骤801中，基站在第一映射关系中确定第二载波集合所指示的预定载波的载波标识，该第二载波集合是根据待激活的载波确定的，且待激活的载波中包括预定载波和至少一个其他载波，或，待激活的载波中包括至少两个其他载波。
其中，载波、预定载波、其他载波的解释详见步骤601中的描述。
在实现本步骤时，基站可以从为UE分配的至少两个载波中确定待激活的载波，确定该待激活的载波所对应的第二载波集合，并预先获取载波标识与第二载波集合的第一映射关系，在该第一映射关系中查找该第二载波集合对应的载波标识。其中，待激活的载波所对应的第二载波集合是指第二载波集合中的载波与待激活的载波完全相同。比如，待激活的载波为载波1、2，则第二载波集合中只包括载波1、2；待激活的载波为载波2、3，则第二载波集合中只包括载波2、3。
在实现时，第二载波集合中包括多个载波是指第二载波集合中包括多个载波的载波标识，由于每个载波标识用于标识一个载波，也就相当于第二载波集合包括多个载波。
比如，第一映射关系中载波标识1所指示的第二载波集合包括载波1-2，载波标识2所指示的第二载波集合包括载波3-4，假设待激活的载波是载波1-2，则基站确定的载波标识为载波标识1，请参考图9。
需要说明的是，第一映射关系可以由基站发送给UE，也可以在通信协议中指定，本实施例不作限定。
当第一映射关系由基站发送给UE时，基站可以将第一映射关系携带在RRC(Radio Resource Control，载波控制)信令或MAC(Medium Access Control，媒体接入控制)CE(Control Element，控制单元)或物理层信令中发送给UE。
在步骤802中，基站在载波标识所标识的预定载波上向UE发送唤醒信息， 该预定载波是分配给UE的至少两个载波中被配置了传输唤醒信息的载波。
比如，基站确定的载波标识为载波标识1，若载波标识1用于标识载波1，则基站确定预定载波是载波1，并在载波1上向UE发送唤醒信息。其中，唤醒信息可以是唤醒信号，也可以是下行控制指令，本实施例不作限定。
需要说明的是，这里所说的唤醒信息的作用是指示UE读取预定载波的载波标识，在一种实现方式中，该载波标识除了可以指示UE激活预定载波，还可以指示UE激活至少一个其他载波；在另一种实现方式中，该载波标识可以指示UE激活至少两个其他载波。
在步骤803中，UE在预定载波上接收唤醒信息。
在步骤804中，UE在第一映射关系中确定预定载波的载波标识所指示的第二载波集合。
在步骤805中，UE激活第二载波集合中的各个载波。
其中，UE根据唤醒信息激活预定载波和至少一个其他载波，或，UE根据唤醒信息激活至少两个其他载波，可以替换为：UE激活第二载波集合中的各个载波。
其中，步骤801-802可以单独实现成为基站侧的实施例，步骤803-805可以单独实现成为UE侧的实施例。
综上所述，本公开提供的载波激活方法，在预定载波上接收唤醒信息，根据该唤醒信息激活预定载波和至少一个其他载波，或，根据唤醒信息激活至少两个其他载波，由于可以通过一条唤醒信息指示UE激活至少两个载波，从而解决了UE需要在每个载波上检测唤醒信息，根据唤醒信息确定是否需要激活该载波的问题，达到了节省UE的能耗，提高UE的续航能力的效果。
图10是根据另一示例性实施例示出的一种载波激活方法的流程图，该载波激活方法应用于图4所示的实施环境中，如图10所示，该载波激活方法包括如下步骤。
在步骤1001中，基站在第二映射关系中确定第三载波集合所指示的载波的载波标识，该第三载波集合是根据待激活的载波确定的，且待激活的载波中包括预定载波和至少一个其他载波，或，待激活的载波中包括至少两个其他载波。
其中，步骤1001的实现流程详见步骤801中的描述。
在步骤1002中，基站生成携带有序列的唤醒信息，该序列用于指示载波标识所标识的载波。
在得到了载波标识后，若唤醒信息为唤醒信号，则基站可以根据步骤601所述的流程生成唤醒信息；若唤醒信息为下行控制指令，则基站可以根据步骤701所述的流程生成唤醒信息。
在步骤1003中，基站在预定载波上向UE发送该唤醒信息，该预定载波是分配给UE的至少两个载波中被配置了传输唤醒信息的载波。
基站确定预先配置的预定载波，在该预定载波上向UE发送唤醒信息。
在步骤1004中，UE在预定载波上接收唤醒信息。
在步骤1005中，UE读取唤醒信息中的序列。
在得到了唤醒信息后，若唤醒信息为唤醒信号，则基站可以根据步骤604所述的流程读取序列；若唤醒信息为下行控制指令，则基站可以根据步骤704所述的流程读取序列。
在步骤1006中，UE在第二映射关系中确定载波标识所指示的第三载波集合，该载波标识是根据序列所指示的载波确定的，该第三载波集合中包括预定载波和至少一个其他载波，或，该第三载波集合中包括至少两个其他载波。
其中，第三载波集合中包括多个载波是指第三载波集合中包括多个载波的载波标识，由于每个载波标识用于标识一个载波，也就相当于第三载波集合包括多个载波。
在步骤1007中，UE激活第三载波集合中的各个载波。
其中，UE根据唤醒信息激活预定载波和至少一个其他载波，或，UE根据唤醒信息激活至少两个其他载波，可以替换为：UE激活第三载波集合中的各个载波。
其中，步骤1001-1003可以单独实现成为基站侧的实施例，步骤1004-1007可以单独实现成为UE侧的实施例。
