具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面首先介绍本公开实施例的实施环境：
图1示例性示出了一种基于网络控制中继器的系统架构的示意图，网络控制中继器(NCR，Network controlled repeater)可以以低成本的方式提高系统覆盖，如图1所示，网络控制中继器由两部分组成，移动终端(NCR-MT，Network controlled repeater Mobile termination)部分可以用来接收网络设备(例如基站、高层网络设备)发送的控制命令，控制命令用于控制转发器(NCR-Fwd，Network controlled repeater-Forwarding)的行为，即回传链路(backhaul link)和接入链路(control link)上的行为，比如波束指示方向、转发的开启和关闭等。其中，参照图1，回传链路可以用于转发器与网络设备通信，接入链路可以用于转发器与用户设备通信，进而使得用户设备能够通过该网络控制中继器与网络设备进行通信。可以理解的是，该网络控制中继器还可以与多个用户设备通信。
具体地，上述高层网络设备可以包括移动性管理网元、会话管理网元、用户面网元以及数据网络(data network，DN)。用户设备可以通过基站以及用户面网元与DN通信。
上述网元既可以是4G架构中的网元、还可以是5G架构中的网元。
数据网络(data network，DN)，为用户提供数据传输服务，可以是协议数据单元(Protocol Data Unit，PDN)网络，如因特网(internet)、IP多媒体业务(IP Multi-media Service，IMS)等。
移动性管理网元可以包括是5G中的接入与移动性管理实体(access and mobility management function，AMF)。移动性管理网元负责移动网络中用户设备和/或网络控制中继器的接入与移动性管理。其中，AMF负责用户设备和/或网络控制中继器接入与移动性管理，NAS消息路由，会话管理功能实体(session management function，SMF)选择等。AMF可以作为中间网元，用来传输用户设备和/或网络控制中继器和SMF之间的会话管理消息。
会话管理网元，负责转发路径管理，如向用户面网元下发报文转发策略，指示用户面网元根据报文转发策略进行报文处理和转发。会话管理网元可以是5G中的SMF，负责会话管理，如会话创建/修改/删除，用户面网元选择以及用户面隧道信息的分配和管理等。
用户面网元可以是5G架构中的用户面功能实体(user plane function，UPF)。UPF负责报文处理与转发。
本公开实施例提供的系统架构中还可以包括数据管理网元，用于处理用户设备和/或网络控制中继器设备标识，接入鉴权，注册以及移动性管理等。在5G通信系统中，该数据管理网元可以是统一数据管理(unified data management，UDM)网元。
本公开实施例提供的系统架构中还可以包括策略控制功能实体(policy control function，PCF)或者为策略计费控制功能实体(policy and charging control function，PCRF)。其中，PCF 或者PCRF负责策略控制决策和基于流计费控制。
本公开实施例提供的系统架构中还可以包括网络存储网元，用于维护网络中所有网络功能服务的实时信息。在5G通信系统中，该网络存储网元可以是网络存储库功能(network repository function，NRF)网元。网络存储库网元中可以存储了很多网元的信息，比如SMF的信息，UPF的信息，AMF的信息等。网络中AMF、SMF、UPF等网元都可能与NRF相连，一方面可以将自身的网元信息注册到NRF，另一方面其他网元可以从NRF中获得已经注册过的网元的信息。其他网元(比如AMF)可以根据网元类型、数据网络标识、未知区域信息等，通过向NRF请求获得可选的网元。如果域名系统(domain name system，DNS)服务器集成在NRF，那么相应的选择功能网元(比如AMF)可以向NRF请求获得要选择的其他网元(比如SMF)。
上述网络设备中的基站可以作为接入网络(access network，AN)的一个具体实现形式，还可以称为接入节点，如果是无线接入的形式，称为无线接入网(radio access network，RAN)，可以为用户设备和/或网络控制中继器提供无线接入服务。接入节点具体可以是全球移动通信(global system for mobile communication，GSM)系统或码分多址(code division multiple access，CDMA)系统中的基站，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(NodeB)，还可以是LTE系统中的演进型基站(evolutional node B，eNB或eNodeB)，或者是5G网络中的基站设备、小基站设备、无线访问节点(WiFiAP)、无线互通微波接入基站(worldwide interoperability for microwave access base station，WiMAX BS)等，本公开对此并不限定。
上述用户设备(user equipment，UE)，也可称为终端、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置等。用户设备可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、物联网终端设备，比如火灾检测传感器、智能水表/电表、工厂监控设备等等。
上述功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。
基于以上的系统架构，波束赋型信息的指示可以通过半静态的方式对回传链路和/或控制链路上的波束进行指示。由于控制链路和回传链路都是NCR和网络设备之间的链路， 因此至少网络控制中继器的移动终端和转发器工作在相同频段或者相近频段的时候，可以假设控制链路和回传链路的大尺度信道特性是相同的，因此在控制链路上使用的波束可以假设为回传链路的波束。
在相关技术中，对于控制链路的波束配置可以是分别针对每个信号/信道进行指示的，也可以是针对多个信道/信号指示的，此时多个信道可以用同一个波束进行指示，下行接收和上行发送比如PUCCH、PUSCH、PDCCH、PDSCH都统一使用一个波束。这样，在进行控制链路波束配置时，可能为移动终端的控制链路配置多个TCI(传输配置指示，Transmission Configuration Indicator)状态以指示多个波束，而在此种情况下，如何更加快速、准确地使得网络控制中继器确定其回传链路应用的最优波束是亟待解决的问题。
具体地，在相关技术中，对于为移动终端的控制链路配置多个波束的情况下，网络控制中继器需要对每一波束进行测试以确定回传链路性能最好的波束，导致波束确定效率低下，无法保证通信的即时性。
为了解决相关技术中存在的问题，本公开实施例提供一种回传链路的波束指示方法、装置及存储介质。
图2是根据一示例性实施例示出的一种回传链路的波束指示方法的流程图，应用于网络控制中继器，如图2所示，方法包括：
S201、网络控制中继器接收网络设备发送的用于配置回传链路的波束的信令，信令包括波束指示信息。
其中，网络设备可以是基站，也可以是高层网络设备，该高层网络设备例如可以是核心网中的网络设备(例如接入与移动性管理实体等)。
S202、网络控制中继器根据波束指示信息，从网络设备为网络控制中继器的控制链路配置的多个波束中确定回传链路使用的目标波束。
其中，该目标波束可以是网络设备确定的为控制链路配置的多个波束中的传输效果较好的波束。
在一示例中，波束指示信息包括波束标识、参考信号标识、波束相关信息、回传链路与网络控制中继器中目标物理信道的绑定关系中的一者或多者。
其中，在波束指示信息包括波束标识、参考信号标识、波束相关信息、回传链路与网络控制中继器中目标物理信道的绑定关系中的多者的情况下，网络控制中继器可以根据不同信息确定目标波束的速率，从波束指示信息中选取确定速率最快的信息用于确定回传链路使用的目标波束。
其中，波束标识(beam ID)以及参考信号标识(RS ID，Reference Signal ID)，与网络设备为网络控制中继器的控制链路配置的多个波束存在一一对应的关系。目标物理信道可以是网络设备与网络控制中继器通信的控制链路中任意一个信道，该目标物理信道可以是网络设备检测到的性能最好的信道。
在一示例中，波束相关信息包括网络设备为控制链路配置的传输配置指示信息、空间关系指示信息以及准同址信息中的一者或多者。
其中，网络控制中继器的控制链路配置的波束时发送的传输配置指示状态(TCI-State)中可以包括用于唯一标识该传输配置指示状态的传输配置指示状态标识(TCI-StateID)，传输配置指示信息可以是传输配置指示中的传输配置指示状态标识(TCI-StateID)。同理，空间关系指示信息可以包括空间关系指示(SRI，spatial relation indicator)对应的唯一标识，准同址信息可以包括准同址(QCL，quasi-co-location)对应的唯一标识。
或者，传输配置指示信息可以是传输配置指示状态，空间关系指示信息可以包括空间关系指示，准同址信息可以包括准同址，本公开对此不作限定。
值得说明的是，传输配置指示状态(TCI-State)中，可以包括准同址(QCL)，其中，准同址可以指示对应的空间接收参数，在假设波束对应(beam correspondence)的情况下，用户设备或者网络控制中继器的空间发送参数和空间接收参数是相同的，进而可以基于该准同址确定波束。另外，不同的准同址类型(QCL type)所包含的信道特性不同，具有QCL关系的两个参考信号具有相同的信道特性。
此外，空间关系指示(SRI，spatial relation indicator)中可以包括网络控制中继器与网络设备之间的空间关系，进而该网络控制中继器可以根据该空间关系从多个波束中确定与该空间关系对应的波束。
采用上述方案，网络设备可以通过发送目标波束对应的传输配置指示信息、空间关系指示信息以及准同址信息任意一个，网络控制中继器即可基于对应的波束指示信息确定该目标波束，无需对为控制链路配置的多个波束一一测试，有效地提高了回传链路的波束确定效率。
在又一些示例中，用于配置回传链路的波束的信令为基站发送的RRC信令，或者，为高层网络设备发送的OAM(Operation Administration and Maintenance，操作管理和维护)消息携带的信令。
可选地，RRC信令是基站通过单播或者组播的方式发送的。
可以理解的是，与基站通信的网络控制中继器可以有多个，对于接入该基站的网络控 制中继器，或者，网络控制中继器组，基站可以针对性地发送RRC信令，以指示每一网络控制中继器，或者每一网络控制中继器组的回传链路使用的波束。
采用上述方案，基站通过单播或组播的方式向网络控制中继器发送RRC信令指示该网络控制中继器回传链路使用的波束，可以根据针对性地进行指示，能够有效地确保每一网络控制中继器回传链路使用的波束的性能。
在本公开实施例中，网络控制中继器通过接收网络设备发送的信令中的波束指示信息，并根据该波束指示信息即可以快速、准确地从网络控制中继器中的移动终端与网络设备通信的控制链路使用的多个波束中，确定网络控制中继器中的转发器与网络设备通信的回传链路使用的波束，网络控制中继器无需对该多个波束一一测试即可以快速地确定回传链路性能较好的波束，有效地提高了通信的效率与性能。
图3是根据一示例性实施例示出的一种回传链路的波束指示方法的流程图，应用于网络控制中继器，如图3所示，方法包括：
S301、网络控制中继器接收网络设备发送的用于配置回传链路的波束的信令，信令包括波束指示信息；其中，波束指示信息包括波束标识或者参考信号标识。
S302、网络控制中继器根据参考信号标识，或者，波束标识确定回传链路使用的目标波束。
可以理解的是，网络控制中继器的控制链路在配置多个波束后，可以对多个波束中的每一波束或者每一波束对应的参考信号进行唯一标识，其中，参考信号标识与参考信号存在唯一对应的关系，波束标识与波束存在唯一对应的关系。
其中，网络设备可以是基站也可以是高层网络设备，信令可以是基站通过单播或组播方式发送的RRC信令，也可以是高层网络设备发送的OAM消息携带的信令，本公开实施例对此不作限定。
采用上述方案，网络控制中继器通过接收网络设备发送的信令中的波束标识或者参考信号标识即可直接的确定网络设备指示的回传链路使用的目标波束，网络控制中继器无需对该多个波束一一测试即可以令回传链路可以快速地确定性能较好的波束，有效地提高了通信的效率与性能。

S502、网络控制中继器根据波束指示信息，从网络设备为网络控制中继器的控制链路配置的多个波束中确定回传链路使用的目标波束。
S503、网络控制中继器根据通信协议中的预设时长或者网络设备配置的预设时长，确定目标波束的生效时间，预设时长为相对特定时刻的时长。
其中，特定时刻包括网络控制中继器接收波束指示信息所在的PDSCH的结束时刻，和/或，网络控制中继器反馈针对包括波束指示信息的PDSCH的HARQ-ACK信息的上行资源的最后一个符号的时刻。
其中，网络设备可以是基站也可以是高层网络设备，信令可以是基站通过单播或组播方式发送的RRC信令，也可以是高层网络设备发送的OAM消息携带的信令，本公开实施例对此不作限定。
示例地，该预设时长可以是X个单位时长，该单位时长可以是一个时隙对应的时长，也可以也一个符号对应的时长或者一个子帧对应的时长，本公开也不做具体限定。
例如，若网络控制中继器接收波束指示信息所在信令的PDSCH的结束时刻为slot n对应的时刻，单位时长为时隙，其中，slot表示时隙，n为时隙的编号，若该网络控制中继 器回传链路使用目标波束的生效时间可以为slot n+X对应的时刻，即在编号为n+X的时隙对应的时刻启用该压缩模型。
采用上述方案，通过在通信协议中规定该预设时长，并基于与波束知识信息对应的特定时刻，确定该目标波束的生效时间，能够使得该网络设备中继器能够基于使用该波束的回传链路与网络设备进行可靠通信，保证了网络设备中继器与网络设备的通信质量。

其中，网络设备可以是基站也可以是高层网络设备，信令可以是基站通过单播或组播方式发送的RRC信令，也可以是高层网络设备发送的OAM消息携带的信令，本公开实施例对此不作限定。
可以理解的是，目标物理信道可以是网络控制中继器的移动终端与网络设备通信的控制链路的一个信道，该信道可以是网络设备确定的通信性能较好的一个信道。
具体地，在步骤S602中以及步骤S603中，网络控制中继器可以根据该绑定关系确定该目标物理信道使用的第一波束的参考信号标识并根据该参考信号标识确定目标波束；或者，可以根据该物理信道使用的波束的波束标识，并根据该波束标识确定目标波束。
采用上述方案，网络控制中继器通过接收网络设备发送的波束信息中的回传链路与网络控制中继器中目标物理信道的绑定关系，根据该绑定关系确定与回传链路绑定的信道使用的目标波束，无需对该多个波束一一测试即可以令回传链路可以快速地确定性能较好的波束，有效地提高了通信的效率与性能。
图7是根据一示例性实施例示出的一种回传链路的波束指示方法的流程图，应用于网络控制中继器，如图7所示，方法包括：
S701、网络控制中继器接收网络设备发送的用于配置回传链路的波束的信令，信令包括波束指示信息；其中，波束指示信息包括回传链路与网络控制中继器中目标物理信道的绑定关系。

其中，网络设备可以是基站也可以是高层网络设备，信令可以是基站通过单播或组播方式发送的RRC信令，也可以是高层网络设备发送的OAM消息携带的信令，本公开实施例对此不作限定。
可以理解的是，在本公开实施例中，目标物理信道使用的第一波束可以是目标物理信道将要使用而还未开始使用的波束。
采用上述方案，在波束指示信息包括回传链路与网络控制中继器中目标物理信道的绑定关系的情况下，回传链路确定的目标波束的生效时间和与该回传链路绑定的目标物理信道使用对应的第一波束的时间一致，可以有效地保证网络控制中继器通过回传链路与网络设备之间的通信的可靠性。

其中，基于该预定义规则确定的在接收到信令之前，和/或，在目标波束生效之前回传 链路使用的波束，可以是网络设备为网络控制中继器的控制链路配置的多个波束之外的波束，也可以是该多个波束中的一个波束。另外，该预定义规则可以是预先配置于该网络控制中继器中的，也可以是通过网络设备发送给该网络控制中继器的。本公开实施例对此不作具体限定。
采用上述方案，通过根据预定义规则确定在接收到信令之前，和/或，在目标波束生效之前回传链路使用的波束，可以确保网络控制中继器的转发器可以在网络设备指示的回传链路的波束生效之前，该回传链路仍然可以有效地基于预定义规则确定的波束进行通信，保证了网络控制中继器与网络设备的通信之间的鲁棒性。

在一示例中，波束指示信息包括波束标识、参考信号标识、波束相关信息、回传链路与网络控制中继器中目标物理信道的绑定关系中的一者或多者。
另外，波束相关信息包括网络设备为控制链路配置的传输配置指示信息、空间关系指示信息以及准同址信息中的一者或多者。
其中，在接收到信令之前对应的第一预定义规则，与在目标波束生效之前对应的第二预定义规则可以相同也可以不同，进而，基于第一预定义规则确定的第二波束与基于第二预定义规则确定的第三波束可以是相同的波束，也可以是不同的波束。基于第一预定义规则与第二预定义确定回传链路使用的波束的方式在下述实施例中将更为详细的介绍，本公开实施例在此不作赘述。
采用上述方案，分别根据第一预定义规则以及第二预定义规则，确定接收到信令之前回传链路使用的波束，以及目标波束生效之前使用的波束，可以保证网络控制中继器在接收到信令之前使用的波束以及目标波束生效之前使用的波束均能够具备较好的通信性能，有效地保证了网络控制设备的转发器与网络设备之间的通信质量。

在一些可选实施例中，网络控制中继器在确定目标波束包括两个波束的情况下，根据目标波束中的第一目标波束进行下行接收，第二目标波束进行上行发送。
其中，第一目标波束与第二目标波束可以是网络中继控制器从目标波束包括的两个波束中随机选取的，也可以是根据预设规则选取的，本公开对此不作限定。

本领域内技术人员可以理解，前述的多个由网络控制中继器执行的实施例和多个由网络设备执行的实施例是相互对应的，因此对于相当的步骤可能只在一侧进行了描述，而另一侧必然执行对应的操作。举例来说，网络设备是广播或通过单播的方式或通过组播的方式向网络控制中继器发送用于配置回传链路的波束的信令；则终端必然会通过对应的方式接收该信令。
