请参见图1，图1为本公开实施例提供的一种通信系统10的架构示意图。该通信系统10可包括但不限于一个网络侧设备和一个终端，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络侧设备，两个或两个以上的终端。图1所示的通信系统10以包括一个网络侧设备101和一个终端102为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络侧设备101是网络侧的一种用于发射或接收信号的实体。例如，网络侧设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络侧设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络侧设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络侧设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端102是用户侧的一种用于接收或发射信号的实体，如手机。终端也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)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)中的无线终端等等。本公开的实施例对终端所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供通信方法、装置及存储介质进行详细地介绍。
相关技术中，波束训练机制为两级训练方法，分别为同步信号块(synchronization signal block，SSB)的宽波束训练和接入后通过信道状态信息参考信号(channel state information reference signal，CSI-RS)进行的窄波束训练。
网络侧设备在发送SSB时会采用不同的波束进行传输，在一个同步脉冲序列集(synchronization signal burst set，SS burst set)中，不同SSB朝不同的方向发送，在终端接入网络侧设备时，接收SSB测得各个SSB对应的同步信号-参考信号接收功率(synchronization signalreference signal received power，或者，synchronization signal based referencesignal received power，SS-RSRP)，并根据测量的结果选择合适的波束。在随机接入过程中，终端会在其选择的波束方向对应的SSB索引(index)关联的随机接入时机发送前导序列，隐式指示网络侧设备合适的发送波束方向。
在终端接入网络后，网络侧设备会配置用于波束训练的参考信号，不同的参考信号对应不同的发射波束。终端通过接收参考信号并测量波束质量选择合适的波束方向，并根据上报设置上报选择结果，网络侧设备和终端可以通过此机制进行更窄的波束训练。
但是，由于更高的频段需要采用更加精细的波束进行传输，终端的轻微移动或是环境的变化都会导致波束方向的重新训练。沿用现有的波束训练框架维护波束方向将给网络侧设备带来极大的训练开销。
基于此，本公开实施例提供一种通信方法、装置及存储介质，以至少解决上述相关技术中存在的技术问题，降低网络测设备用于维护更加精细的波束的开销，解决更高的频段中波束训练开销大的问题。
请参见图2，图2是本公开实施例提供的一种通信方法的流程图。
如图2所示，该方法由网络侧设备执行，该方法可以包括但不限于如下步骤：
S21：向终端发送无线资源控制RRC消息，RRC消息包括第一指示信息，第一指示信息用于指示下行控制信息DCI中包括第一指示参数；向终端发送DCI，DCI包括第一指示参数，第一指示参数用于指示一组信道状态信息参考信号CSI-RS资源。
其中，网络侧设备向终端发送的无线资源控制(radio resource control，RRC)消息，RRC消息中包括第一指示信息，RRC消息携带的第一指示信息可以为新增的参数信息，或者为RRC消息中原有参数信息进行重新定义的，本公开实施例对此不作具体限制。
本公开实施例中，网络侧设备可以向终端发送包括第一指示信息的RRC消息，以指示DCI中包括第一指示参数，终端在接收到包括第一指示信息的RRC消息之后，能够对第一指示参数进行理解，进而终端根据第一指示参数执行相应的动作，从而开启三级波束训练机制。
其中，第一指示参数可以为DCI中的新增字段，其用于指示一组信道信息参考信号CSI-RS资源。从而网络侧设备发送DCI之后，能够通过新增字段的第一指示参数指示一组CSI-RS资源，网络侧设备可以采用更加精细的波束传输每个CSI-RS，例如：网络侧设备可以调整加在发射天线阵列上的导向矢量，以控制传输波束的宽度，从而采用更加精细的波速传输每个CSI-RS。
本公开实施例中，网络侧设备向终端发送DCI，可以采用较宽的波束传输DCI，例如：网络侧设备可以调整加在发射天线阵列上的导向矢量，以控制传输波束的宽度，以采用较宽的波束传输DCI。网络侧设备可以通过第一指示参数指示一组CSI-RS资源。
需要说明的是，本公开实施例中，在不需要开启三级波束训练机制的情况下，网络侧设备不向终端发送包括第一指示信息的RRC消息，而此时，DCI中可以包括第一指示参数或者还可以不包括第一指示参数，可以理解的是，在DCI中包括第一指示参数的情况下，由于终端未接收到网络侧设备发送的包括 第一指示信息的RRC消息，终端将无法理解DCI中的第一指示参数，终端将无法根据第一指示参数执行相应的动作，由此，也不会开启三级波束训练机制。
基于此，本公开实施例中，网络侧设备可以根据需要，发送包括第一指示信息的RRC消息或者发送不包括第一指示信息的RRC消息，以在真正需要传输数据时，开启三级训练机制，向终端发送包括第一指示参数的DCI，进行更加精细的波束训练。
通过实施本公开实施例，向终端发送无线资源控制RRC消息，RRC消息包括第一指示信息，第一指示信息用于指示下行控制信息DCI中包括第一指示参数；向终端发送DCI，DCI包括第一指示参数，第一指示参数用于指示一组信道状态信息参考信号CSI-RS资源。通过这种方式，能够在网络侧设备真正需要传输数据时再进行更加精细的波束训练，从而降低网络测设备用于维护更加精细的波束的开销，解决更高的频段中波束训练开销大的问题。

其中，网络侧设备发送的一组CSI-RS，每个CSI-RS对应第一指示参数中的一个CSI-RS资源的资源编号，终端接收网络侧设备发送的一组CSI-RS，反馈一个波束对应的CSI-RS资源的资源编号，从而可以确定波束为网络侧设备发送资源编号对应的CSI-RS使用的波束资源，以在后续网络侧设备向终端发送信息时使用该波束。

本公开实施例中，网络侧设备向终端发送物理下行共享信道PDSCH，之后发送一组CSI-RS，网络侧设备会采用更加精细的波束传输每个CSI-RS，每个CSI-RS对应第一指示参数中的一个CSI-RS资源的资源编号，终端接收网络侧设备发送的一组CSI-RS，需要反馈一个最佳波束的信息，也即反馈一个波束对应的CSI-RS资源的资源编号，从而可以确定该波束为网络侧设备发送资源编号对应的CSI-RS时使用的波束资源，以在后续网络侧设备向终端发送信息时使用该波束。
其中，终端可以在PDSCH的HARQ资源上反馈该波束的信息，也即复用PDSCH的HARQ资源反馈该波束对应的CSI-RS资源的资源编号。
本公开实施例中，网络侧设备可以在接收到终端的反馈之后，根据反馈的结果用于后续针对该终端的数据传输，由此，网络侧设备能够在没有数据传输时，维护一个较宽的波束，并在真正传输数据时，再进行更加精细的波束训练，从而能够降低网络侧设备维护更加精细的波束的开销，同时能够提高 PDSCH的传输效率，解决更高频段中波束训练开销大的问题。
需要说明的是，S41可以单独被实施，也可以结合本公开实施例中的任何一个其他步骤一起被实施，例如结合本公开实施例中的S21和/或S31一起被实施，本公开实施例并不对此做出限定。

其中，第二指示参数可以为DCI中的新增字段，其用于指示终端反馈波束对应的CSI-RS的资源编号所使用的第一上行反馈资源，从而，终端在接收到包括第二指示参数的DCI之后，能够在第一上行反馈资源上反馈波束对应的CSI-RS的资源编号。
可以理解的是，终端接收到包括第一指示信息和第二指示信息的RRC消息，以及接收到包括第一指示参数和第二指示参数的DCI之后，能够在接收网络侧设备发送的一组CSI-RS之后，确定一个波束对应的CSI-RS资源的资源编号之后，在第二指示参数指示的第一上行反馈资源上反馈该波束对应的CSI-RS的资源编号。

需要说明的是，S61可以单独被实施，也可以结合本公开实施例中的任何一个其他步骤一起被实施，例如结合本公开实施例中的S21和/或S31和/或S51一起被实施，本公开实施例并不对此做出限定。
在一些实施例中，在未接收到终端反馈的波束对应的CSI-RS的资源编号的情况下，在第一波束上向终端发送PDSCH，第一波束与终端反馈的波束不同。
