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：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11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，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，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、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11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，终端11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。

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和终端11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，终端11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。

如图2所示，本申请实施例提供一种载波聚合方法，包括：
步骤S101：确定在非授权频段上进行载波聚合的主载波；
步骤S102：在所述主载波上触发载波聚合的执行。
本实施例中提供一种载波聚合方法，该载波聚合方法应用于各种通信设备中，具体如，该载波聚合方法应用于有需求利用载波聚合技术进行数据发送的发送端。
进行载波聚合时进行聚合的载波可分为：主载波和副载波。
所述主载波，是相对于副载波而言，主载波除了用于传输数据外，还会传输用于与载波聚合相关的控制信令，例如，控制载波聚合开始、结束的控制信令等，以及调度副载波上的数据传输的控制指令。该控制信令还可包括：控制载波聚合的其他载波聚合参数，例如，该载波聚合参数用于指示以下至少之一但不限于：利用载波聚合技术传输数据时所使用帧格式、子帧格式等。再例如，所述与载波聚合相关的控制指令还可包括：指示终端在副载波上进行信道检测的控制指令。
在另一些实施例中，所述主载波还可用于传输与载波聚合无关的其他控制信令。
在一些实施例中，所述主载波还可用于传输反馈信息。例如，所述主载波还可以用于传输载波聚合传输的数据的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈；该HARQ反馈包括主载波所传输数据的HARQ反馈，和/或副载波所传输数据的HARQ反馈。所述HARQ反馈包括但限于：指示数据传输成功的确认字符(Acknowledgement character，ACK)和/或，指示数据传输失败的否认字符(Non Acknowledgement character，NACK)。
所述副载波，又可以称为辅载波。在本实施例，所述副载波主要辅助主载波的传输。
在本实施例中，进行载波聚合的所使用的频段为非授权频段。进行载波聚合的主载波和至少一个副载波都是来自非授权频段。
在本实施例中，所述非授权频段上的载波聚合，根据载波聚合的数量可分为：双载波聚合及多载波聚合，多载波聚合实现的2个以上的载波聚合。例如，双载波聚合将使用到一个主载波和一个副载波；而多载波聚合将使用到一个主载波和两个或两个以上的副载波。
在本实施例中，所述非授权频段上的载波聚合，根据聚合的载波的频点分布，可包括：
非授权频段的同一个频带内的连续载波聚合；
非授权频段的同一个频带内的非连续载波聚合；
非授权频段的不同频段的带间载波聚合。
参考图3所示，载波1和载波2来自非授权频段的同一个频带且频点连续的载波，是一种频带内连续载波聚合。
参考图4所示，载波1和载波2来自非授权频段的同一个频带的频点不连续的载波，是一种频带内不连续载波聚合。
参考图5所示，载波1和载波2来自非授权频段的不同频带的载波，是一种频带间载波聚合。由于载波1和载波2来自不同的频带，不同的频带所对应的频点范围是不同的，故载波1和载波2是另一种非连续载波聚合。
在本实施例中，所述主载波上传输的控制信令还可包括：载波聚合的载波数量和/或载波的频点等指示信息。
所述非授权频段可认为是一种公共频段，通信设备基于竞争机制使用所述非授权频段进行数据传输。在使用非授权频段之前，可以使用信道检测技术对非授权频段进行监听，基于监听的结果进行非授权频段的竞争等。
例如，在5G新无线(New Radio，NR)中存在以下非授权频段：5G NR技术包含LWA(LTE-WLAN aggregation,LTE-WiFi链路聚合)、LTE-U(LTE unlicensed，非授权频段LTE)、LAA(licensed-assisted access,许可辅助接入)等频段。
在本实施例中，在进行载波聚合的操作之前，先确定出主载波。然后在主载波上触发载波聚合的执行。
所述步骤S102可包括：在主载波上发送进行载波聚合的通知或指令，如此收发双端都知道当前启动了载波聚合传输。
本申请实施例的载波聚合是在非授权频段上执行的，而非限于授权频段，如此，相当于扩大了进行载波聚合的频段，减少了因为局限于授权频段导致的载波聚合所使用频段少进而导致载波聚合的机会少和失败率高的问题，与此同时，本申请实施例还规范了在非授权频段上进行载波聚合的方式，触发载波聚合的执行是由主载波上传输的指令或通知来实现的，如此，一旦主载波确定，可以通过主载波的监听，就能够及时的获取是否进行载波聚合的指令，减少传输方法因为载波聚合的通知或指令没有及时传输导致的接收效果差的问题；提升了利用载波聚合技术进行数据传输的效果。
在一些实施例中，所述步骤S101可包括：
根据预先配置的载波信息，确定在所述非授权频段上进行载波聚合的所述主载波。
在本实施例中，基站等网络侧设备可以预先配置进行载波聚合的载波信息，该载波信息中包含有主载波的载波标识等。故在本实施例中，发送端可以根据预先配置的载波信息，确定出在非授权频段上进行载波聚合的主载波。
例如，基站会预先配置终端可以用于进行载波聚合的载波信息。如 此，终端根据载波信息就可以知道在非授权频段上载波聚合的主载波。
例如，基站在完成载波信息的配置之后，会利用授权频段或非授权频段发送给终端。具体地如，基站会利用物理层信令或者高层信令将所述载波信息发送给终端。该物理层信令包括但不限于：利用物理下行控制信道(Physical Downlink Control Channel，PDCCH)下发的下行控制信息(Downlink Control Information，DCI)等。所述高层信令包括但不限于媒体访问控制层(Medium Access Control，MAC)信令或者无线资源控制(Radio Resource Control，RRC)信令。
通过授权频段或非授权频段上各种控制信令携带所述载波信息发送给终端，如此终端就可以简便的根据所述载波信息确定出在非授权频段上进行载波聚合的主载波。
基站下发所述载波信息的信令可包括：广播信令、组播信令或者单播信令。
在本实施例中，所述载波信息包括：指示载波聚合的载波聚合关系的信息。该载波聚合关系至少可用于表征载波聚合的主载波和副载波。
在一些实施例中，所述方法还包括：
在所述主载波上执行信道检测；
或者，
在所述主载波和副载波上执行信道检测。
在本实施例中，在进行确定载波聚合之前，可进行载波的信道检测。
具体如，在主载波上执行信道检测，例如，对主载波进行信道侦听。
在一个实施例中，在主载波上进行信道检测，不在副载波上进行信道检测；在检测到主载波空闲时，如果需要执行载波聚合操作，就可以在主载波上触发载波聚合的操作；然后执行步骤S102触发执行载波聚合。
在另一个实施例中，进行信道检测的一端会在主载波上和至少一个 副载波上执行信道检测。例如，在主载波和所有的副载波上都进行信道检测。再例如，在主载波和部分副载波上执行信道检测。
在完成了信道检测之后，将根据信道检测的检测结果，确定是否执行载波聚合、执行载波聚合的时间等与载波聚合相关的载波聚合参数。
在一些实施例中，所述步骤S102可包括：
在检测到所述主载波空闲时，在所述主载波上触发载波聚合的执行。
在本实施例中，在主载波通过所述信道检测(例如，当前时刻主载波是空闲的)时，在主载波上触发载波聚合的执行，此处的触发载波聚合的执行，包括：发送执行载波聚合的通知和指令。
在一些实施例中，所述方法还包括：
当发送端为终端时，所述终端将执行信道检测的检测结果上报给基站；
所述步骤S102，包括：
在所述主载波上，接收基站基于所述检测结果下发的触发执行载波聚合的执行指令。
在本实施例中，若有数据要发送的发送端为终端时，终端将在主载波执行信道检测的检测结果上报给基站，或者，终端将在主载波和副载波上执行信道检测的检测结果均上报给基站。
如此，基站在接收到所述检测结果之后，会决策是否进行载波聚合和/或决策出进行载波聚合的载波聚合参数。该载波聚合参数包括：载波聚合的时间参数、载波聚合的频率参数、载波聚合的载波数量、载波聚合的方式参数等。
在执行载波聚合时，终端会收到基站在主载波上下发触发执行载波聚合的执行指令。
终端接收到该执行指令，可根据执行指令和/或进行载波聚合的载波 信息，激活载波聚合功能。
在一些实施例中，所述方法还包括：
当发送端为终端时，所述终端接收基站下发的所述载波信息；
所述步骤S101可包括：
所述终端根据所述载波信息指示的所述载波信息，确定在所述非授权频段上进行载波聚合的所述主载波。
若发送端为终端，终端会接收基站下发的所述载波信息，该载波信息可为携带在基站下发的各种信令或消息中，例如，该载波信息可携带在前述实施例提供的授权频段的广播信息、组播消息或单播信息中。
如此，终端在步骤S101中将根据从基站接收的载波信息，确定在非授权频段上进行载波聚合的所述主载波。
在一些实施例中，如图6所示，所述方法还包括：
向所述基站上报所述终端的载波聚合能力信息，
所述接收基站下发的所述载波聚合的载波信息，包括：
接收基站基于所述载波聚合能力信息下发的所述载波信息。
终端还会事先将自身的载波聚合能力信息发送给基站，以供基站确定是否允许终端进行载波聚合和/或如何执行载波聚合。
在一些实施例中，终端可以在授权频段或非授权频段上向基站上报所述载波聚合能力信息。具体的如，终端可以通过授权频段的上行信道上报所述载波聚合能力信息，具体如，可以通过授权频段的物理上行控制信道(Physical Uplink Control Channel，PUCCH)上报所述载波聚合能力信息。
在一些实施例中，终端在与基站建立RRC连接的过程中，上报所述载波聚合能力信息。具体地，基站下发了RRC连接建立消息；终端接收到RRC连接建立消息之后，向基站返回基站RRC连接建立完成消息； 在该RRC连接建立完成消息中可携带有所述载波聚合能力信息，如此，在终端和基站完成RRC连接建立的过程中，同步完成了所述载波聚合能力信息的上报；如此，无需引入额外的信令进行所述载波聚合能力信息的上报。
在另一些实施例中，终端可以在与基站完成RRC连接建立之后，主动上报所述载波聚合能力信息。
在另一些实施例中，终端在于基站RRC连接重建立过程中，所述载波聚合能力信息可以携带在RRC连接冲配置完成消息中一同发送上报给基站。
基站在接收到所述载波聚合能力信息之后，会根据该终端的载波聚合能力信息来配置，以与终端的载波聚合能力相适配；减少配置的载波信息并不与终端的载波聚合能力匹配导致的载波聚合失败现象。
在一些实施例中，所述载波聚合能力信息用于指示以下至少之一：
所述终端是否支持在非授权频段上进行载波聚合；
所述终端支持的最大载波聚合数量。
在一些实施例中，所述载波聚合能力信息还可以用于指示：终端是否支持在授权频段上进行载波聚合；或者，终端是否支持载波聚合。
只要在终端支持在非授权频段上进行载波聚合时，才执行所述步骤S101至步骤S102。
终端支持的最大载波聚合数量，例如，有的终端仅支持双载波聚合，有的终端却可以支持两个或两个以上的载波聚合。
在为终端配置载波聚合的载波信息时，载波信息所指示的载波聚合的载波个数不超过所述终端支持的最大载波聚合数量。
在一些实施例中，所述载波聚合能力信息还可用于指示终端支持的载波聚合的载波之间的频点间隔等。
在一些实施例中，所述步骤S101可包括：根据动态确定的载波信息，确定所述主载波。
在前述实施例中，载波信息是预先配置的。在本实施例中，所述载波信息可为动态确定的。
如此，在步骤S101中可以根据动态确定的载波信息确定所述主载波。
具体如，至少对非授权频段的一个或多个载波进行信道检测，在检测到至少一个载波空闲时，可将最早检测到的空闲载波作为载波聚合的主载波。在确定主载波之后，就会将该载波的载波标识作为主载波标识写入到载波信息中。
在本实施例中，动态确定进行载波聚合的所述载波信息，如此，即相当于动态确定载波聚合的主载波；如此，可以动态的根据非授权频段上载波的闲忙状况，灵活配置载波聚合的相关信息；如此相对于静态配置，可以增大载波聚合的操作次数和实现成功率。
在一些实施例中，所述方法还包括：
当发送端为基站时，所述基站在所述非授权频段的载波上进行信道检测；
所述基站将最早检测到的空闲载波作为所述动态确定的载波信息所指示的所述主载波。
若进行信道检测的是基站，则基站将在非授权频段的多个载波上进行信道检测，然后将最早检测到的空闲载波作为主载波，并根据确定的主载波生成确定所述载波信息。
在本实施例中，最早检测到的空闲载波作为主载波，能够尽可能快的实现载波聚合，减少载波聚合的时延，减少载波聚合起始时间晚导致的传输效率低的现象。在一些实施例中，所述步骤S102可包括：在确定所述主载波后，在所述主载波向终端发送进行触发执行载波聚合的执行 指令。
基站在确定主载波之后，若确定需要执行载波聚合，会在主载波上向终端发送触发执行载波聚合的执行指令，如此，终端在接收到所述执行指令会执行载波聚合的操作。
在一些实施例中，所述方法还包括：
当发送端为终端时，所述终端在所述非授权频段的载波上进行信道检测，获得检测结果；
将所述检测结果上报给基站，其中，所述检测结果用于供所述基站确定所述主载波。
在发送端为终端时，终端会在非授权频段的载波上进行信道检测，获得检测结果，通过检测结果上报给基站，由基站最终确定选择主载波，和/或决策是否执行载波聚合。
具体如，具体如，基站将根据所述检测结果动态确定所述载波信息。
在本申请实施例中，所述载波信息用于指示以下至少之一：
主载波；
载波带宽；
主载波的频点；
副载波的频点。
所述载波信息可包括：指示所述主载波的载波标识；指示载波带宽的带宽信息；指示主载波和/或副载波所对应频点的频点信息等。
在有的情况下，一个载波的最大带宽为20MHz；在有的情况下，一个载波的最大带宽可达80MHz。图10展示的为一个带宽为80MHz的载波，该载波分为了4个带宽部分，分别是带宽部分1、带宽部分2、带宽部分3及带宽部分4，其中，每一个带宽部分为20MHz。
如图7所示，本实施例提供一种载波聚合装置，包括：
第一确定模块71，被配置为确定在非授权频段上进行载波聚合的主载波；
触发模块72，被配置为在所述主载波上触发载波聚合的执行。

在还有一些实施例中，所述载波信息用于指示以下至少之一：

载波带宽；

以下结合上述任意实施例提供几个具体示例：
示例1：
本申请中给出了在非授权频段上实现载波聚合的方法，可以有效的支持在非授权频段上支持数据速率要求比较高的业务传输。
本申请中提出的方法如下：
终端上报自己的载波聚合能力信息。所述载波聚合能力信息指示了终端的载波聚合能力。例如，该载波聚合能力信息至少用于指示：终端是否支持在非授权频谱上支持载波聚合；终端最大能支持的载波聚合数量等信息。
终端可以通过在授权频段或是非授权频段上上报该载波聚合能力信息。例如，终端可以在建立RRC连接的过程中或是建立RRC连接之后与基站的通信过程中上报该能力。
载波聚合关系可以预先配置，也可以动态确定；若载波聚合关系预先配置，则会预先配置形成前述的载波信息。
在预先配置载波聚合关系的情况下，当终端具备在非授权频段上进行载波聚合的能力时，基站会预先配置终端可以用于载波聚合的载波信息，所述载波信息可以用于指示以下至少之一：
主载波，载波带宽，参与载波聚合的载波所对应频点等信息。
发送端在非授权频谱上进行操作时，具体的载波聚合方式可以包括但不限于以下几种：
第一种：在可以作为主载波的载波上执行信道检测等操作，在确定了主载波之后，可以通过主载波来控制副载波上的操作，比如信道接入机制，一些控制信息的通知等。
第二种：在所有载波上执行信道检测操作。当可以工作的载波是副载波时，无法执行载波聚合的操作。
针对第一种：仅在主载波上进行信道检测的操作时，发送端(例如基站或终端)也可以优先在载波1上执行信道检测，若检测到对应的载波空闲，就占用该载波以进行载波聚合。当成功占用到载波1后，在指示在载波2和载波3上的操作。
针对第二种：在所有载波上执行信道检测的操作时，可如图8所示：当发送端是基站时，基站预先确定载波1作为载波聚合操作时的主载波，载波2和载波3作为载波聚合操作时的副载波。
基站可以在载波1，载波2和载波3上都执行信道检测，当基站检测到载波2或是载波3空闲，基站可以在载波2和载波3上进行数据传输，但是无法触发载波2和载波3上的载波聚合操作。当检测到载波1空闲，占用载波1，并可以在载波1上触发载波聚合的执行，聚合空闲的载波2和/或载波3。同理，当发送端是终端时，终端接收基站的指示预先确定载波1作为载波聚合操作时的主载波，载波2和载波3作为载波聚合操作时的副载波。终端在载波1，载波2，载波3上执行信道检测，并通知基站检测结果。基站基于检测结果决定是否触发载波聚合的执行。
示例2：
在动态确定载波聚合关系的情况下，当终端在非授权频段上进行载波聚合的能力时，基站会在所有的载波上执行信道检测的操作，当在某个载 波上成功占用信道之后，可以在该载波上触发终端进行载波聚合的操作。
触发终端进行载波聚合的操作可包括但不限于：
通知终端聚合载波的信息；
在副载波上的信道接入机制，控制信息的传输等。
如图9所示，当发送端在任何一个载波上通过了信道检测，可以确定该载波为主载波，在其上触发和执行载波聚合的操作。本申请中给出了在非授权频段上实现载波聚合的方法，可以有效的支持在非授权频段上支持数据速率要求比较高的业务传输。
在发送端(基站或终端)分别在非授权频段的载波1、载波2及载波3上都进行信道检测，若检测到有空闲的载波都可以作为主载波，以触发载波聚合的执行。在本示例中，会将最早检测到的空闲载波作为主载波，触发载波聚合的执行。例如，在图10中最早检测到空闲载波为载波2，基站会将载波2配置为载波聚合的主载波，形成动态确定的载波信息。
如此，比对图8所示的预先配置载波1为主载波，在载波1、载波2和载波3的空闲状况相同时，由于载波信息的配置方式不同，进入会导致载波聚合的开始时间不同和使用的主载波不同。
本实施例还提供一种通信设备，包括：
天线；
存储器；
处理器，分别与所述天线及存储器连接，用于通过执行存储在所述存储器上的可执行程序，控制所述天线收发无线信号，并能够执行前述任意实施例提供的所述载波聚合方法的步骤。
