背景技术
在无线通信网络中，载波聚合(carrier aggregation，CA)技术可通过多个载波(例如主载波和辅载波)为终端提供更多的传输带宽，从而获得更高的传输速率。CA技术中支持对辅载波的激活和去激活操作，例如可通过媒体接入控制(media access control，MAC)控制元素(control element，CE)激活辅载波。然而，由于MAC CE的处理时间较长，导致激活辅载波需要较长的时间，无法快速的满足大带宽业务的需求。因此，如何能够更快地激活辅载波，成为亟需解决的问题。

具体实施方式
本申请实施例提供的通信方法及装置可以应用于通信系统中。如图1示出了一种通信系统结构示意图。该通信系统中包括一个或多个网络设备(清楚起见，图中示出网络设备10和网络设备20)，以及与该一个或多个网络设备通信的一个或多个终端设备。图1中所示终端设备11和终端设备12与网络设备10通信，所示终端设备21和终端设备22与网络设备20通信。可以理解的是，网络设备和终端设备也可以被称为通信设备。
本发明实施例描述的技术可用于各种通信系统，例如2G，3G，4G，4.5G，5G通信系统，多种通信系统融合的系统，或者未来演进网络。例如长期演进(long term evolution，LTE)系统，新空口(new radio,NR)系统，无线保真(wireless-fidelity，WiFi)系统，以及第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的蜂窝系统等，以及其他此类通信系统。
图2示出了通信系统的一种可能的架构举例示意图，如图2所示无线接入网(radio access network，RAN)中的网络设备是集中单元(centralized unit，CU)和分布单元(distributed unit,DU)分离架构的基站(如gNodeB或gNB)。RAN可以与核心网相连(例如可以是LTE的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通 过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如分组数据汇聚层协议(packet data convergence protocol，PDCP)层及无线资源控制(radio resource control,RRC)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(media access control，MAC)层，物理(physical)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。图2所示的网络架构可以应用于5G通信系统，其也可以与LTE系统共享一个或多个部件或资源。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现，也可以进一步将控制面(CP)和用户面(UP)分离，即CU的控制面(CU-CP)和用户面(CU-UP)可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。
可以理解的是，本申请中提供的实施例也适用于CU和DU不分离的架构。
本申请中，网络设备可以是任意一种具有无线收发功能的设备。包括但不限于：LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，NR中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point,TRP)，3GPP后续演进的基站，WiFi系统中的接入节点，无线中继节点，无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，中继站，或，气球站等。多个基站可以支持上述提及的同一种技术的网络，也可以支持上述提及的不同技术的网络。基站可以包含一个或多个共站或非共站的TRP。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、CU，和/或，DU。网络设备还可以是服务器，可穿戴设备，或车载设备等。以下以网络设备为基站为例进行说明。所述多个网络设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端设备进行通信，也可以通过中继站与终端设备进行通信。终端设备可以与不同技术的多个基站进行通信，例如，终端设备可以与支持LTE网络的基站通信，也可以与支持5G网络的基站通信，还可以支持与LTE网络的基站以及5G网络的基站的双连接。
终端是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、可穿戴终端设备等等。本申请的实施例 对应用场景不做限定。终端有时也可以称为终端设备、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、终端设备、无线通信设备、UE代理或UE装置等。终端也可以是固定的或者移动的。
在无线通信网络中，例如长期演进(long term evolution，LTE)或新空口(new radio，NR)中，为满足更大峰值速率的需求，需要提供更大的传输带宽。由于大带宽连续频谱的稀缺，载波聚合(carrier aggregation，CA)成为提供更大传输带宽的一种解决方案。CA是将两个或更多个成员载波(component carrier，CC)聚合在一起以支持更大的传输带宽。CC一般可分为主成员载波(primary component carrier，PCC)和辅成员载波(secondary component carrier，SCC)。其中，PCC也可以被称为主载波或主小区(primary cell，Pcell)中，SCC也可以被称为辅载波或辅小区(secondary cell，Scell)。
考虑终端的功耗，CA中提供辅载波的激活和去激活机制，以在终端需要更大传输带宽时激活辅载波，而在终端不需要大传输带宽时去激活辅载波起到节省电量的作用。网络设备可以通过终端的上报信息获知终端的辅载波是否已完成激活。例如，终端向网络设备上报辅载波的信道状态信息(channel state information，CSI)报告，网络设备通过该CSI报告可以获知终端的上述辅载波已经完成激活。
激活辅载波的机制可以通过媒体接入控制的控制单元(media access control control element，MAC CE)实现。然而，由于MAC CE的处理时间较长，导致激活辅载波需要较长的时间，无法快速的满足大带宽业务的需求。因此，如何能够更快地激活辅载波，成为亟需解决的问题。
本申请实施例提供的方法中，通过使用物理层信令触发待激活辅载波的CSI操作，使得辅载波的激活更加快速，从而减少了辅载波的激活时间，进而满足业务的时延需求。
下面以具体实施例结合附图对本申请的技术方案进行详细说明。下述实施例和实施方式可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。应理解，本申请中所解释的功能可以通过独立硬件电路、使用结合处理器/微处理器或通用计算机而运行的软件、使用专用集成电路，和/或使用一个或多个数字信号处理器来实现。当本申请描述为方法时，其还可以在计算机处理器和被耦合到处理器的存储器中实现。

本申请中的非周期CSI上报可理解为通过信令触发的一次或多次CSI上报。例如，终端可以接收用于触发非周期CSI上报的DCI，对测量结果(例如通过非周期CSI测量或半持续CSI测量获周期性测量获得的测量结果)进行一次或多次上报(例如上报给网络设备)。非周期CSI上报的测量结果也可称为非周期CSI报告。
可以理解，用于触发非周期CSI测量的DCI和用于触发非周期CSI上报的DCI可以是同一个DCI，也可以是不同的DCI。
本申请中的半持续CSI测量可理解为通过信令触发的在一段时间内的至少一次CSI测量。例如，终端可以接收用于触发半持续CSI测量的DCI，在一段时间内对CSI-RS进行至少一次测量，该CSI-RS可以是周期性、或半持续性的。
本申请中的半持续CSI上报可理解为通过信令触发的在一段时间内的至少一次CSI上报。例如，终端可以接收用于触发半持续CSI上报的DCI，在一段时间内对测量结果(例如通过半持续CSI测量或周期性测量获得的测量结果)进行至少一次上报(例如上报给网络设备)。半持续CSI上报的测量结果也可称为半持续CSI报告。
