请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个基站12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进 行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实 施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，通过波束管理确定载波1的最优波束为波束i，载波2的波束i与载波1的波束i方向不一致，如果采用统一波束管理在载波2上选择波束i，会导致该载波2上的链路性能较差，甚至失去连接，为了减少这一现象，同时尽可能的在支持统一波束管理时，采用统一波束管理以减少波束管理的信令开销。如图3所示，本实施例提供一种波束管 理方法，其中，应用于基站中，包括：
S110：根据终端的波束管理能力信息，下发对辅载波进行单独波束管理的配置信息。
本申请实施例应用于各种类型的基站中，例如，4G基站或5G基站等。
基站在给终端配置载波时，针对支持多载波的终端，可以为终端配置一个主载波和一个或多个辅载波。终端可以在主载波上收发控制信令，根据该控制信令控制终端在主载波和/或辅载波上的传输行为。
在一些实施例中，所述主载波为中终端的服务小区的载波；所述辅载波可为终端的服务小区的邻小区的载波。
所述波束管理能力信息指示：终端对多个载波采用统一管理方式的能力强弱。例如，所述波束管理能力信息的信息内容可包括以下一项或多项；
所述终端的多载波统一管理能力强弱等级的指示信息；
所述终端进行多载波统一管理能力时支持的载波间最大频域相对位置的指示信息。
不同的多载波统一管理能力强弱等级，对应了不同的多载波统一管理能力强弱的载波间最大频域相对位置；等级越高，则进行多载波统一管理时支持的载波间最大频域相对位置越大。例如，指示终端的多载波统一管理能力强弱等级可分为：2个等级、3个等级或者4个等级等。例如，在分为2个等级时，终端的多载波统一管理能力强弱可分为“低”及“高”两个等级，等级越高，则说明终端的多载波统一管理能力强弱越强，支持频域相对位置越远的两个载波之间的统一管理。在分为3个等级时，终端的多载波统一管理能力强弱可分为“低”、“中”、及“高”，在分为4个等级时，终端的的多载波统一管理能力强弱可分为“低”、“较 低”、“较高”及“高”。若波束管理能力信息是直接指示等级，则可以用一个或多个比特直接指示等级，例如，用1个比特指示两个等级，用2个比特指示3个等级或4个等级等。
此处的是采用统一管理方式即：为了减少单独管理每一个波束导致的信令开销大，会认为主载波和至少一个辅载波的最优波束方向是一样的。实际应用时，由于终端的软硬件能力及不同载波的频率不同，实质上任意两个载波的最优波束方向可能是存在一定偏差，但是有的情况下，这种偏差是可以接受的，即对通信质量的影响较小，但是有的情况下两个载波的最优波束方向存在较大偏差，若此时基于同一个管理方式进行波束管理，会导致在对应载波上的通信质量差，甚至出现链路断开的现象。
例如，有的终端的终端能力比较强，例如，包含较多天线或者这些天线之间的覆盖范围比较大的终端，具有的载波的统一管理能力就比较强，如此，即便两个载波实际上的最优波束方向偏差比较大，但是还是在终端的天线的覆盖范围内，则可以采用载波的统一管理方式进行波束管理，从而减少信令开销。但是有的终端的天线少或者天线阵列的覆盖范围小的情况下，仅采用载波的统一管理方式是，就可能会导致上述通信质量差甚至链路断开的现象。
为了解决上述现象，针对副载波，基站在为终端进行载波管理配置时，会根据终端的波束管理能力信息，会确定是否要为终端的辅载波皮遏制单独的波束管理。即S110可包括：当根据终端的波束管理能力信息确定出需要对终端的辅载波进行单独波束管理时，下发对辅载波进行单独波束管理的配置信息；和/或当根据终端的波束管理能力信息确定出不需要对终端的辅载波进行单独波束管理时，不下发对辅载波进行单独波束管理的配置信息，可仅下发主载波的波束管理的配置信息。
在本申请实施例中，终端的主载波默认是配置波束管理的。若确定该终端直接采用统一波束管理，则仅会在主载波上进行波束测量，基于主载波上的波束测量确定最优波束方向。然后统一以主载波上进行波束测量得到的最优波束方向，视为该终端的所有载波上的最优波束方向。例如，一个终端配置有N个载波，其中，一个主载波和N-1个辅载波；N为等于或大于2的正整数。若采用统一波束管理，则会基于主载波上的波束测量得到的主载波上的最优波束方向，同时视为主载波和辅载波上的所有载波的最优波束方向。
但是若根据终端的波束管理能力信息，确定出当前为终端配置的主载波和辅载波采用基于主载波的统一波束管理的话，可能会导致为辅载波上确定的最优波束方向，与辅载波的实际最优波束方向偏差太大的现象，则此时需要对辅载波进行单独的波束管理。
在本申请实施例中，波束管理包括以下一项或多项：
波束测量，包括：在对应载波上的各个波束上发送参考信号，对参考信号进行测量得到测量结果；
波束测量结果的上报；
波束指示，例如，终端或基站指示在任意一个为终端配置的辅载波上进行通信的波束；
波束恢复，包括：波束失效之后如何进行一个或多个载波上的波束恢复。
总之，在本申请实施例中，不会直接对终端采用基于一个载波(例如，主载波)的统一波束管理方式，而是会根据终端的波束管理能力信息，确定是否需要为其配置的辅载波单独进行波束管理，减少统一采用基于主载波的统一波束管理导致的在辅载波上的通信质量差及甚至链路失效的现象。
基站在根据终端的波束管理能力信息确定出为终端配置的至少一个辅载波需要进行单独波束管理时，为下发辅载波的单独波束管理的配置信息，该辅载波的单独波束管理的配置信息，可以与主载波的波束管理的配置信息一同下发，也可以单独下发辅载波的单独波束管理的配置信息。例如，在一些实施例中，所述方法还包括：
根据是否为终端的辅载波是否需要单独管理的确定结果，下发终端进行载波管理的配置信息；
终端会根据所述配置信息进行载波管理。例如，若为终端配置了辅载波的单独管理，则终端会根据所述配置信息进行辅载波的单独管理，终端进行所述辅载波的单独管理包括：在辅载波上进行参考信号测量和/或上报测量结果。
所述配置信息包括：基于主载波进行波束管理的第一配置；或者，基于主载波进行波束管理的第一配置及基于辅载波进行波束管理的第二配置。
所述第一配置至少包括：在所述主载波上发送参考信号的时频域资源。所述第二配置至少包括：在所述辅载波上发送参考信号的时频域资源。
在一些实施例中，所述第一配置和第二配置还包括：测量结果的上报条件和/或测量条件等。测量条件，用于指示终端进行对应载波上参考信号的条件，例如，当前选定的波束的波束质量低于质量阈值时，进行主载波和辅载波的波束重新测量，以重新确定主载波和/或辅载波的最优波束方向想。上报条件，用于指示终端进行对应载波上参考信号之后，需要上报的测量结果，有的测量结果相当于指示当前选定的波束方向即为主载波和/或辅载波的最优波束方向，则可以不用上报；例如，通过波束测量发现最优波束方向发生了变化，则可上报重新确定的最优波束方 向。
在一些实施例中，如图4所示，所述S110，包括：
S111：确定出所述终端的主载波与任意一个所述辅载波之前的频域相对位置；
S112：根据所述频域相对位置及所述波束管理能力信息，确定所述辅载波是否满足辅载波单独波束管理条件；
S113：当所述辅载波满足所述辅载波单独波束管理条件时，下发对满足所述辅载波单独波束管理条件的辅载波进行单独波束管理的所述配置信息。
不同载波具有不同的频率。如此，不同载波在频域是有一定位置偏移量的。在本申请中会使用频域相对位置来衡量两个载波在频域的相对位置。
若两个载波的频率差比较大，由于不同的频率在相同信道内的传输效果是不一样的，如此可能会导致两个载波的最优波束方向的偏差较大。故在本申请实施例中，会结合任意辅载波和主载波之间的频域相对位置和终端的波束管理能力信息，确定为该终端配置的辅载波是否满足辅载波单独波束管理条件，则需要单独在该辅助上进行波束管理。
总之在本实施例中，会确定任意一个辅载波和主载波之前的频域相对位置和终端的波束管理能力信息所对应的最大频域相对位置进行比较，某一个辅载波的频域相对位置，小于前述终端的管理能力信息指示的波束管理能力所对应的最大频域相对位置，则可认为该辅载波不满足辅载波单独波束管理条件，该辅载波满足基于主载波的统一管理条件。若满足统一管理条件，则该辅载波基于该主载波的统一管理条件，仅对主载波进行波束测量等波束管理，将主载波的波束管理直接认定为是对该辅载波的波束管理。
在一些实施例中，所述S112可包括：
根据所述频域相对位置及所述波束管理能力信息，确定出存在与所述主载波之间的的所述频域相对位置超出所述终端基于所述主载波的统一管理能力时，确定与所述主载波之间的频域相对位置超出所述终端基于所述主载波的统一管理能力范围的所述辅载波满足所述辅载波单独波束管理条件。
在一些实施例中，所述波束管理能力信息指示统一波束管理的最大相对频域位置为XMhz，若频域相对位置对应的频率差大于XMhz，则确定满足所述辅载波单独波束管理条件，否则可认为不满足辅载波单独波束管理条件。
在另一些实施例中，表征频域相对位置的频率比值，大于波束管理能力对应的最大比值时，则可认为满足所述辅载波单独波束管理条件，否则认为不满足所述辅载波单独波束管理条件。
总之，在本申请实施例中，指示所述频域相对位置的相对位置参数有很多种，可以将相对位置参数与该相对位置参数所对应的阈值进行比较，基于阈值比较的结果，确定是否满足辅载波单独波束管理条件。
通常情况下，两个载波之间的频率差越大，则越有可能需要进行单独波束管理。
例如，所述频域相对位置由以下参数至少之一指示：
所述主载波和所述辅载波的中心频率的频率差；例如，主载波的中心频率为f1、辅载波的中心频率为f2；该频率差为f1-f2或f2-f1；
所述主载波和所述辅载波的中心频率差，与所述主载波和所述辅载波的中心频率和的比值；该比值可为：(f2-f1)/(f1+f2)。在一些实施例中，还可以预定倍数比值，A*(f2-f1)/(f1+f2)，该A可为任意正数，例如A可为0到1之间的任意小数、A可为1、2或3。
所述主载波所在频段和所述辅载波所在频段的频率差。该频率差可为两个频段的中心频率的频率差。例如，主载波所在频段A，辅载波所在频段B，频段A的中心频率f11；频段B的中心频率f12；则此时所述主载波所在频段和所述辅载波所在频段的频率差为：f11-f12或f12-f11。
在一些实施例中，所述频域相对位置还可以由主载波和辅载波之间的比值。主载波的中心频率为f1、辅载波的中心频率为f2，则该比值为：f1/f2或者f2/f1。
图8A所示的载波1和载波2是位于相同的频带A上，两者之间的载波间隔可为两个载波中心频率的频率差，这种频率差即为前述的频域相对位置的一种。
图8B所示的载波1和载波2是位于不同的频带上，载波1位于频带A上，载波2位于频带B上，两者之间的载波间隔可为两个载波中心频率的频率差，这种频率差即为前述的频域相对位置的一种。
在一些实施例中，如图5所示，所述方法还包括：
S101：向终端发送多载波的波束管理能力的上报指示；
S102：接收终端根据所述上报指示发送的所述波束管理能力信息。
基站下发上报指示，该上报指示在终端进行多载波进行传输，则指示进行波束管理能力信息的上报。
在一些实施例中，基站可以就终端主动上报的波束管理能力信息，也可以是根据终端的终端类型推测波束管理能力信息。
通过上报指示的下发，触发有需要的终端进行波束管理能力信息上报，减少信令开销；相对于基站记录所有终端的波束管理能力信息，可以减少终端存储的信息量。
在一些实施例中，所述方法还包括：
当存在需要单独管理的辅载波时，在所述辅载波上发送参考信号；
接收终端对所述参考信号的测量结果。
若存在需要单独管理的副载波，即存在满足辅载波单独波束管理条件的辅载波，则在该辅载波上发送参考信号，例如，使用该载波在各个波束方向上发送参考信号，接收终端对参考信号的测量结果，从而可以确定出在该辅载波的最优波束方向。
进一步地，在一些实施例中终端可能支持一个主载波和多个辅载波，此时，若有一个辅载波已经确定需要单独管理，剩余辅载波在确定是否需要单独管理时，不仅需要根据剩余辅载波与主载波之间的频域相对位置确定是否要单独管理，同时还需要和已确定需要单独管理的辅载波之间的频域相对位置，进一步确定是否是可以和已确定需要单独管理的辅载波之间进行统一波束管理。在本申请实施例中，将已确定需要单独管理的载波称为第一载波，该第一载波包括但不限于：主载波和已确定需要单独管理的辅载波。将尚未确定需要单独管理的辅载波可称之为第二载波；在具体的实现过程中，可以根据第二载波和各个第一载波之间的频域相对位置及终端的波束管理能力信息，确定对应的第二载波是否可以和某一个第一载波进行统一波束管理，若可以，则该第二载波与其中某一个第一波束进行统一波束管理，否则可认为需要进行单独波束管理。如此，在终端存在多个辅载波时，若有两个辅载波之间的频率相差较小，导致的最优波束方向的偏差较小的情况下，可以使得这两个辅载波之间采用统一波束管理，以进一步减少波束管理导致的信令开销。此处，第一载波和第二载波之间确定频域相对位置的方式，及判断是否采用单独波束管理或波束统一管理方式的方式，可以参见本申请实施例中，主载波和辅载波的频域相对位置的确定及是否满足辅载波单独波束管理条件的判定，此处就不赘述了。
在基站侧进行辅载波的单独波束管理时，所述方法还可包括：
在辅载波上以不同方向的波束发送参考信号；
接收终端对参考信号的测量结果，该测量结果包括但不限于波束的参考信号接收功率和/或参考信号接收质量；在一些实施例中，该测量结果还可以是终端基于测量选择的最优波束的波束索引等最优波束方向的指示信息。
此处的参考信号包括但不限于：信道状态信息参考信号(Channel Status Information-Reference Signal，CSI-RS)。例如，该参考信号还可包括：同步信号。该同步信号包括：主同步信号和/或辅同步信号。
如图6所示，本实施例提供一种波束管理方法，其中，应用于终端中，包括：
S210：接收对辅载波进行单独波束管理的配置信息，其中，所述配置信息是基于所述终端的管理能力信息确定的；
S220：根据所述配置信息，进行辅载波的单独波束管理。
本申请实施例波束管理方法所应用的终端可为各种类型的终端，包括但不限于：手机、可穿戴式设备或平板电脑等用户终端、还可以是车载终端、智能家居和/或智能办公设备等。
在本申请实施例中，终端接收基站下发的辅载波单独波束管理的配置信息，该配置信息包含有用于终端单独进行波束管理的配置信息，此时，终端接收到该配置信息之后，就可以针对辅载波单独进行波束管理。值得注意的是，在本申请实施例中，辅载波的单独波束管理可认为是区分主载波的波束管理而言的，即若一个辅载波进行单独波束管理(或波束的单独管理)则认为：该辅载波和主载波需要分别进行波束测量，基于波束测量结果，分别选择该辅载波和主载波的最优波束方向的测量。此处的波束测量包括：通过参考信号的发送进行波束质量和/或接收功率的测量。
如此，终端根据基站的配置信息进行载波的波束管理时，不会仅进行基于主载波的统一波束管理，或者，针对每一个主载波和辅载波的单独波束管理，而是会根据终端的波束管理能力信息，在有需要进行辅载波的单独波束管理时，可以辅载波单独的波束管理，从而确保使用辅载波通信时能够确保最优波束方向，确保通信质量。在无需进行辅载波的单独波束管理时，则进行基于主载波的统一波束管理，以减少波束管理的信令。
在本申请实施例中，所述方法还包括：
上报终端的波束管理能力信息，其中，所述波束管理能力信息，用于供基站确定是否需要单独管理所述终端的辅载波。
基站获取终端的波束管理能力信息的方式有多种，例如，可包括中单上报波束管理能力信息。此处终端的波束管理能力信息的上报，包括但不限于终端主动上报，也可以是基于基站的上报指示的上报。
故在一些实施例中，如图7所示，所述方法还包括：
S201：接收基站下发的上报指示；
S202：根据所述上报指示，上报所述波束管理能力信息。
在一些实施例中，所述S220可包括：
根据所述配置信息，确定出当存在需单独管理的辅载波时，在所述辅载波上接收参考信号；
上报所述参考信号的测量结果。
此处测量的参考信号包括但不限于CSI-RS等。在一些实施例中，总之，本申请实施例所述的参考信号是各种用于测量不同波束方向的波束质量的参考信号。
终端扫描同一个载波上不同波束方向上的波束发送的参考信号，确定在一个载波在不同波束方向上的接收质量，然后可以根据接收质量选 择使用主载波和任意一个辅载波的最优波束方向。基于选择的最优波束方向进行通信，能够确保通信质量。
上报的测量结果可包括以下一项或多项：
在各个波束方向的参考信号接收功率；
在各个波束方向的参考信号接收质量；
最优波束方向的波束索引；
最优波束方向的波束索引集合，该波束索引集合对应于一个或多个波束索引。

下发单元，被配置为当所述辅载波满足所述辅载波单独波束管理条件时，下发对满足所述辅载波单独波束管理条件的辅载波进行单独波束管理的所述配置信息。
在一些实施例中，所述第二确定单元，被配置为根据所述频域相对位置及所述波束管理能力信息，确定出存在与所述主载波之间的的所述频域相对位置超出所述终端基于所述主载波的统一管理能力时，确定与所述主载波之间的频域相对位置超出所述终端基于所述主载波的统一管理能力范围的所述辅载波满足所述辅载波单独波束管理条件。

以下结合任意一个实施例提供几个示例：
示例1：
本公开针对现有波束管理方案未考虑不同终端的能力，对所有的多载波场景采用统一的波束管理方案，可能会造成某些载波上的波束方向比较差，从而影响链路性能。为了减少上述问题，本示例提供的方案依据终端的不同能力选择不同波束管理方案，既可以避免了能力差终端选择了较差的波束方向，又可以节省能力强的终端的信令开销。
本示例提供的波束处理方法的应用场景包括但不限于以下至少之一：
指载波聚合技术，双链接技术(DC，Dual connectivity)还可以包括多接入系统的双链接技术(Muti-RAT dual connectivity，MRDC)，如，4G网络辅节点的双连接(EUTRA-NR Dual Connection，EN-DC)EN-DC和5G网络(NR-E-UTRA Dual Connectivity，NE-DC)NE-DC等。
基站侧向终端发射消息要求终端上报多载波情况下波束管理能力，终端上报所述多载波情况下波束管理能力，基站根据所述终端上报的多载波波束管理能力确定是否有载波需要进行单独的波束管理。具体的流程示意 图11所示，包括：
S601：基站向终端发射消息要求终端上报多载波波束管理能力，例如，基站通过上报指示，要求终端上报多载波波束管理能力；
S602：终端反馈多载波波束管理能力，例如，终端通过波束管理能力信息指示自身对多载波的波束管理能力；
S603：基站根据终端反馈的多载波管理能力，确定哪些波束需要进行单独波束管理；
S604：对终端进行波束管理。
示例2：
基站在给终端配置其他载波(此处的其他载波至少包括辅载波)时，向终端发射消息要求终端上报多载波情况下波束管理能力，终端上报所述多载波情况下波束管理能力，基站根据所述终端上报的多载波波束管理能力确定是否有载波需要进行单独的波束管理。
在一个实施例中，所述终端上报的波束管理能力可通过比特(bit)值指示能力的差别，比如“低”，“中”，“高”，或者“低”和“高”等。基站收到该信息后，根据波束管理所在的载波，即基站在该载波上需要发射参考信号或者同步信号，一般为主载波，以及需要配置的辅载波之间的位置关系是否满足要求终端上报的要求，如果超出要求，则判断辅载波上需要做单独的波束管理，即发射参考信号。
所述“低”，“中”，“高”，的确定方法可根据不同的频段和载波的不同位置来确定。在一个实施例中可依据如下确定。
设两个载波在频段A(Band A)的中心频点为f1和f2,根据参数：F1＝2*(f2-f1)/(f1+f2)的值来确定。比如F1小于某一值X1时，认为是“低”；在X1和X2之间是“中”；大于X2，认为是“高”。其中，X2大于X1。此处，X1和X2均为用于确定终端所支持的频域相对位置的阈值。
所述根据不同的频段和载波的不同位置来确定能力等级的方法，在另一个实施例中，可直接根据两个载波间的距离差来决定。如参数F2＝f2-f1，然后依据F2小于某一值Y1时，认为是“低”；在Y1和Y2之间是“中”；大于Y2，认为是“高”。X2大于X1。
基站收到终端的上报的能力等级，比如某个终端在该频段A上报的能力等级为“低”，则基站根据需要给该终端配置的载波信息，计算出F1，或F2是否大于X1或者Y1；
如果是，则基站判断需要在辅载波上配置进行波束管理的参考信号如CSI-RS(Channel State Information Reference Signal)或同步信号块(Synchronization signal block，SSB)信号。终端扫描该信号，根据信号的强度如最大的参考信号接收功率(Reference Signal Receiving Power，RSRP)来确定该辅助载波上的下行接收的最佳波束(beam)i。
如果否，基站无需在该辅载波上进行波束管理，即无需在该载波上额外发射参考信号如CSI-RS(Channel State Information Reference Signal)或SSB信号。即如果主载波上终端的最佳波束方向为i，则其它辅载波上也采用该波束方向i。
示例3：
在一个实施例中所述终端上报的波束管理能力，可直接上报具体的参数值。如例1中的F1或者F2，具体的参数值上报方法，依据需要上报的精度来确定需要的比特数量。如2比特(bit)的信息，可上报四种不同的值，下表以F1上报为例。
F1对应的值 比特(Bit)值
F1_1 00
F1_2 01
F1_3 10
F1_4 11
表1
基站收到终端的上报的能力等级对应的具体参数值，则基站根据需要给该终端配置的载波信息，计算出F1，或F2是否大于X1或者Y1，如果是，则基站判断需要在辅载波上配置进行波束管理的参考信号；如果否，基站无需在该辅载波上进行波束管理，即无需在该载波上额外发射参考信号。
示例4：
在另一个实施例中，如果基站需要配置的辅载波在另一个频段上。如图8B所示，载波1在频段A(Band A)上，而载波2在频段B(Band B)上。一些方案中可能对于这种频段间的载波聚合直接采用独立的波束管理，这种方案虽然能搞保证辅载波上的比较优的性能，但需要额外的信令开销。但实际上一些终端设计能力较强，或者两个频段如频段A和频段B之间的频率间隔不太大，依然可以采用共同的波束管理。因此，同样为了考虑终端的能力，因此上述例1、例2和例3中的方法依然可使用。
