具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请实施例提供的方法进行详细介绍之前，先对本申请实施例涉及的相关术语和实施环境进行简单介绍。
载波聚合(Carrier Aggregation，CA)
为了满足高速率的需求，5G中也支持载波聚合技术。
载波聚合是通过联合调度和使用多个成员载波(Component Carrier，CC)上的资源，使得新空口(New Radio，NR)系统可以支持更大的频段(band)，从而能够实现更高的系统峰值速率。根据所聚合载波在频谱上的连续性可以分为：连续性载波聚合和非连续性载波聚合。根据聚合的载波所在的频段(band)是否相同，分为频段内(Intra-band)载波聚合和频段间(Inter-band)载波聚合。
Scell激活
在一种实现方式中，辅载波的相关配置由主小区的基站通过RRC专用信令向用户设备(User Equipment，UE)进行配置。初始配置的辅载波状态为去激活状态，然后基站通过媒体接入控制控制信元(Medium Access Control Control Element，MAC CE)进行Scell的激活才能进行数据收发。在另一种实现方式中，辅载波的相关配置由主小区的基站通过RRC专有信令向UE进行配置，配置后默认处于激活状态。
以主小区的基站采用MAC CE信令来激活为例，结合参考图1，Scell激活包括如下几个步骤：
1、在时刻t1，主小区的基站向UE发送MAC CE，该MAC CE携带有辅载波激活(Scell activation)指示。UE接收MAC CE。
2、在时刻t2，UE向主小区的基站反馈混合自动重传请求确认(Hybrid Automatic Repeat request Acknowledge，HARQ ACK)。
3、在时刻t2至时刻t3，UE内部对MAC CE进行解码和处理，比如将MAC CE中的。
4、UE在时刻t3之后，对AGC进行设置，与辅小区进行时频域定时同步，然后等待接收辅小区的第一个同步信号块(Synchronization Signal Block，SSB)。等待第一个SSB的时长可视为T FirstSSB。
5、在时刻t4，UE监听到辅小区的第一个SSB，获知辅小区的信道状态参考信号(Channel State Information Reference Signal，CSI-RS)发送配置。
6、在时刻t5，UE根据监听到的CSI-RS，生成信道状态反馈报告；
7、在时刻t6，UE向辅小区的基站上报信道状态反馈报告。UE生成和上报信道状态反馈报告的时间可视为T CSI_Reporting，基站在获知UE的信道状态反馈后，调度UE进行数据传输。
在上述过程中，由于辅小区的SSB的周期较长，使得Scell激活过程带来的时延较大(也即上述T FirstSSB所导致的时延较长)，所以在相关技术中，决定引入相位参考信号(Tracking Reference Signal，TRS)来辅助UE快速激活Scell。
AGC
自动增益控制电路是在输入信号幅度变化较大时，能使输出信号幅度稳定不变或限制在一个很小范围内变化的特殊电路，简称为AGC电路。自动增益控制(AGC)电路是无线电接收设备中的重要电路，用来保证接收幅度的稳定，已广泛用于各种接收机、录音机和信号采集系统中，另外在光纤通信、微波通信、卫星通信等通信系统以及雷达、广播电视系统中也得到了广泛的应用。
在CA场景中，每一个载波的激活或者去激活，UE都需要重新设置AGC。在传统方案中都是AGC基于SSB信号的接收能量设置的。但是为了降低Scell激活时延，相关技术的Scell的激活过程决定采用TRS来代替SSB。相应地，AGC也要基于TRS的接收能量设置。目前，TRS的发送功率信息可以通过高层信令配置，例如powerControlOffsetSS{db-3,db0,db3,db6},即相对于辅同步信道的功率密度差-3db,0db,3db,6db。
在CA场景中，为了降低成本，减少终端复杂度，LNP(低噪声放大器)由一个频段的多个载波共享，因此，AGC设置时需要已经激活的或正在激活的载波上信号的功率信息，保证AGC的输出不会超过一定的门限，避免超出后续处理期间的有效工作区间。
在如图2所示的CA场景中，在t1时刻，UE接收到辅载波激活指示。在t2时刻，已经激活(active)的第一载波上发送第一SSB，正在激活(to be active)的第二载波上发送第二SSB。第一SSB和第二SSB需要在同一时隙发送。UE根据第一SSB和第二SSB的接收功率之和来设置AGC，以保证AGC的设置合理，AGC的输出不会超过一定的门限值。
同理，当采用TRS代替SSB的场景中，如图3所示。在t1时刻，UE接收到辅载波激活指示后。在t3时刻，已经激活的第一载波上发送第一TRS，正在激活的第二载波上发送第二TRS。第一TRS和第二TRS需要在同一时隙发送。UE根据第一TRS和第二TRS的接收功率之和来设置AGC，以保证AGC的设 置合理，AGC的输出不会超过一定的门限值。
但是由于TRS对于Pcell/PScell/Scell都是额外增加的信号，它会对已经在这些小区或载波上传输的终端受到影响，传输资源减少，甚至是干扰。
图4示出了本申请一个实施例提供的系统架构的示意图。该系统架构可以包括：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备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。
网络设备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。网络设备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系统中，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB或者接入网设备。随着通信技术的演进，“网络设备”这一名称可能会变化。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网络设备。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
在示例性的CA场景中，主小区/主辅小区对应一个单独的网络设备20，辅小区对应另一个单独的网络设备20，两个网络设备20之间可以通过光缆通信。
图5示出了本申请一个示例性实施例提供的载波激活方法的流程图。本实施例以该方法应用于终端中来举例说明。该方法包括：
步骤502：接收参考信号，参考信号的发送功率由同一个频带内的第一载波和第二载波上的信号发送功率确定，或，参考信号的发送功率由同一个频带内的第二载波上的信号发送功率确定；
终端是使用频段内(Intra-band)载波聚合或频段间(Inter-band)载波聚合的终端。
示例性的，参考信号是用于辅助终端进行第二载波激活的参考信号。参考信号包括以下信号中的至少一种：TRS、CSI-RS、主同步信号(Primary Synchronisation Signal，PSS)、辅同步信号(Secondary Synchronisation Signal，SSS)。本实施例中，以参考信号是TRS来举例说明。
示例性的如图6所示，该参考信号仅在正在激活的第二载波上发送，不需要在已经激活的第一载波上发送。终端在正在激活的第二载波上接收该参考信号，而无需在已经激活的第一载波上接收该参考信号。或者说，参考信号未在已经激活的第一载波上发送。
在本实施例中，该参考信号的发送功率是基于终端在同一个频段x上所使 用的所有载波上的信号发送功率来确定的。该频段x是正在激活的第二频段所在的频段。第二终端在该频段x上所使用的载波包括：已经激活的第一载波和正在激活的第二载波，或者，仅包括正在激活的第二载波。
其中，第一载波是已经激活的一个或多个载波，第二载波是正在激活(或即将激活)的一个或多个载波。图6中以第一载波和第二载波均为一个载波来举例说明。
在频段内载波聚合场景下，终端使用的频段可以为一个，在该频段中同时存在第一载波和第二载波。参考信号的发送功率由该频段中的第一载波和第二载波上的信号发送功率确定。或者说，参考信号的发送功率由该频段中的所有第一载波和所有第二载波上的信号发送功率确定。或者说，参考信号的发送功率由第一载波上的第一信号和第二载波上的第二信号的信号发送功率确定。其中，第一信号和第二信号是参考信号。比如，第一信号是第一SSB信号，第二信号是第二SSB信号。
在频段间载波聚合场景下，终端使用的频段可以为至少两个。假设正在激活的第二载波在频段x上。对于终端来讲：
若频段x上还存在已经激活的第一载波，则参考信号的发送功率由该频段x中的第一载波和第二载波上的信号发送功率确定。或者说，参考信号的发送功率由该频段x中的所有第一载波和所有第二载波上的信号发送功率确定。或者说，参考信号的发送功率由该频段x中的第一载波上的第一信号和第二载波上的第二信号的信号发送功率确定。其中，第一信号和第二信号是参考信号。比如，第一信号是第一SSB信号，第二信号是第二SSB信号。
若频段x上不存在已经激活的第一载波，也即已经激活的第一载波在其它频段y上，则参考信号的发送功率由该频段x中的第二载波上的信号发送功率确定。或者说，参考信号的发送功率由该频段x中的所有第二载波的信号发送功率确定。或者说，参考信号的发送功率由该频段x中的第二载波上的第二信号的信号发送功率确定。其中，第二信号是参考信号。比如，第二信号是第二SSB信号。
步骤504：基于参考信号激活第二载波；
终端基于参考信号的接收功率设置AGC；根据设置后的AGC激活第二载波。也即，终端在接收到该参考信号后，根据该参考信号的接收功率设置AGC(或调整AGC)。在设置AGC后，完成与辅小区的时频域同步、CSI测量和CSI报告，从而完成第二载波的激活，等待网络设备调度在第二载波上的数据传输。
示例性的，在CA场景中，第一载波包括主载波/主辅载波(PCell/PScell)，或者，第一载波包括主载波/主辅载波+辅载波(Scell)；第二载波包括辅载波(Scell)。
参考图6，在t1时刻，UE接收到Scell激活指示。在t4时刻，UE在正在激活的Scell上接收TRS，该TRS的发送功率由Pcell上的SSB的发送功率和Scell上的SSB的发送功率共同确定。UE在接收到该TRS后，根据该TRS的接收功率对自身的AGC进行合理设置。在设置AGC后，完成与Scell的时频域同 步、CSI测量和CSI报告，从而完成Scell的激活，等待网络设备调度在Scell上的数据传输。
综上所述，本实施例提供的方法中，由于参考信号的发送功率是由同一个频带内的第一载波和第二载波上的信号发送功率确定的，因此终端仅需要根据该单个参考信号的接收功率即可完成AGC的合理设置，从而基于该单个参考信号即可完成第二载波的激活过程。
在本实施例提供的方法中，由于终端仅需要根据该参考信号的接收功率即可完成AGC的合理设置，因此该参考信号可以仅在第二载波上发送，无需在第一载波上发送，从而减少对传输资源的占用，以及减少对其它终端的干扰。
