具体实施方式
下面详细描述本公开的实施例，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。
随着无线通信技术的发展，新型互联网应用诸如车车通信(vehicle-to-vehicle communication，V2V)的涌现对于无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足应用的需求。当下，蜂窝移动通信技术正在处于新一代技术的演进阶段。其中，新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。
在具体的应用场景下，由于不同的业务类型对于无线通信技术有不同的要求，如增强移动宽带(enhanced Mobile Broad Band，eMBB)业务的需求侧重在大带宽、高速率等方面；超可靠低时延通信(Ultra Reliable Low Latency Communication，URLLC)业务的需求侧重在较高的可靠性以及低的时延方面；大规模机器式通信(massive Machine Type Communication，mMTC)业务的需求侧重在海量的连接数方面。可见，新一代的无线通信系统需要灵活、可配置的设计来支持多种业务类型的传输需求。
在相关技术中，中继是提高网络覆盖范围的简单、低成本的手段。目前，射频中继在第二代至第四代移动通信技术中进行了大量部署，用来补充覆盖，第五代移动通信技术(Fifth Generation，5G)在Rel-17标准协议中对射频中继进行了研究。第三代合作伙伴计划(Third Generation Partnership Project，3GPP)R18标准协议中启动对网络控制中继(Network-controlled Repeater，NCR)的研究，为中继引入一定的辅助信息和控制信令，比如，支持波束测量和波束控制，从而进一步提高中继的性能。
然而，目前5G NR所支持的中继为射频中继，其仅能够实现对信号的接收、射频转换和放大转发功能，不受基站控制，也并不支持波束赋形等操作，无法针对特定区域进行波束调整，也无法实现在用户移动过程中针对特定用户进行跟踪，使得系统性能在特定场景或复杂应用环境下受到限制。
为此，本公开提出了一种基于波束配置的通信方法、装置及系统，提供了一种适用于智能中继的波束管理方案，实现波束调整和赋形，有效提高通信系统灵活性和可配置性，为多种业务类型和复杂通信场景下的传输需求提供支撑。
可以理解的是，本公开提供的方案可以用于第五代移动通信技术(Fifth Generation，5G)及其后续通信技术，诸如第五代移动通信技术演进(5G-advanced)、第六代移动通信技术(SixthGeneration，6G)等，在本公开中不予限制。
下面结合附图对本申请所提供的基于波束配置的通信方法及装置进行详细地介绍。
图1示出了根据本公开实施例的一种基于波束配置的通信方法的流程示意图。如图1所示，该方法应用于第一网络设备。在本公开的实施例中，第一网络设备可以理解为基站，具体地，在5G通信场景中为gNB(next Generation Node B)。
该方法可以包括以下步骤。
S101，根据第二网络设备的能力信息，配置第二网络设备与终端之间的配置波束，并发送配置波束的配置信息。
在本公开的实施例中，第二网络设备可以理解为中继，例如智能中继(Smart repeater)。具体地，第二网络设备可以是网络控制中继(Network-controlled Repeater，NCR)。
可以理解的是，在本公开中，基站、中继以及终端之间的通信可分为配置阶段和指示阶段。其中，配置阶段发生于基站与中继之间，指示阶段发生于基站与中继或基站与终端之间。
在配置阶段，基站可以根据中继的能力信息，配置中继与终端之间所使用的波束，换言之，本方案中基站对于中继和终端之间使用的波束具有控制和决策能力。中继的能力信息包括中继的波束赋形能力、每个单元波束的索引以及波束信息中的至少一项，其中波束信息包括单元波束的方向信息和/或宽度信息，例如，相对于天线的阵列法线方向，每个波束的方向及角度范围。
S102，基于终端上报的波束测量结果，生成并发送波束指示信息。
其中，波束指示信息用于辅助中继和/或终端生成发送波束或者接收波束。
在本公开的实施例中，终端能够根据基站配置的配置波束的相关信息进行波束测量，从而获得测量结果并上报至基站，基站根据该测量结果，生成能够辅助中继和/或终端生成发送波束或接收波束的波束指示信息。
在本公开实施例中，波束测量结果为终端根据基站发送的配置波束的配置信息进行波束测量而获得的结果。例如，终端可以基于基站发送的配置波束的配置信息，对中继和终端之间使用的配置波束进行测量，该结果可以表征配置波束的波束质量，其可以使用任意能够衡量波束质量的参数，在本公开中不予限制。
换言之，在指示阶段，基站能够对所配置的波束向中继和/或终端进行指示，以在中继和终端之间使用所配置的波束。可以理解的是，基站对中继的指示与基站对终端的指示可以相互独立且隔离。
综上，根据本公开实施例提供的基于波束配置的通信方法，第一网络设备通过配置第二网络设备与终端之间的配置波束，并发送配置波束的配置信息，并基于终端上报的波束测量结果，可以生成并发送波束指示信息，该波束指示信息用于辅助第二网络设备和/或终端生成发送波束或者接收波束，从而实现波束调整和赋形，有效提高通信系统灵活性和可配置性，为多种业务类型和复杂通信场景下的传输需求提供支撑。

在本公开的实施例中，中继可以对所支持的单元波束进行全量上报，基站接收到上报的能力信息后，可以进行选择和决策。例如，中继上报64条波束的信息，基站能够判断是否直接使用或对其中的某些波束进行配置，从而针对特定区域或特定用户进行调整。
在本公开中，单元波束的方向信息和/或宽度信息可以理解为每个波束相对于天线的阵列法线方向的方向及角度范围。
S202，根据第二网络设备的能力信息，配置第二网络设备与终端之间的配置波束。
在本公开的实施例中，基站可以在配置阶段根据中继的能力信息配置中继与终端之间所使用的波束，即配置波束。中继与终端之间所使用的配置波束的生成方式包括：一个配置波束对应于一个单元波束；和/或一个配置波束由两个及两个以上单元波束合并形成。
在本公开的实施例中，配置波束指的是一个或多个配置波束，其中，每个配置波束均包括一个单元波束和/或由两个及两个以上单元波束合并形成的合并波束。换言之，本公开所描述的配置包括选择和组合，基站可以根据中继的能力信息配置一个或多个配置波束，其中每一个配置波束可以是上报能力中的某一个单元波束，也可以是多个单元波束的合成波束。
举例而言，中继上报了64个单元波束的信息，其能够达到360度的覆盖，基站可以根据中继的能力、网络覆盖情况、终端移动情况以及特定区域的具体场景等因素，选择或组合适用于当前场景的波束。应当说明的是，本公开重点关注通信过程中的信令交互，即，基站的输入和输出，对于基站的决策过程及其决策因素在此不予限制，基站可以根据任何通信场景中关注的因素进行决策。
在本公开的一些可选实施例中，基站可以对配置波束进行配置，从而获得配置波束的配置信息。其中，配置信息可以包括配置波束的索引信息和/或构成信息和/或测量参考信号的测量参考信号配置信息。
具体地，在一些可选实施例中，对配置波束进行配置的步骤具体包括：配置该配置波束的索引信息。例如，基站可以直接使用中继上报的单元波束的索引，或者为配置波束重新建立波束索引。
上述构成信息指的是，该配置波束是由哪个或哪些单元波束构成，其中包括各个单元波束的索引信息。
在一些可选实施例中，对配置波束进行配置的步骤具体还包括：对该配置波束配置测量参考信号(即关联参考信号)。

在一些可选实施例中，基站可以向中继发送配置波束的配置信息。
在一些可选实施例中，基站可以向中继发送测量参考信号配置信息，以辅助中继生成测量参考信号的发送波束，以发送测量参考信号。
可以理解的是，中继可以基于从基站接收的测量参考信号配置信息，生成测量参考信号的发送波束，从而向终端设备发送测量参考信号，以供终端设备对各个配置波束的测量参考信号进行测量。
在一些可选实施例中，基站可以向终端发送测量参考信号配置信息，以辅助终端基于该测参考信号配置信息对测量参考信号进行波束测量。其中，基站可以直接向终端发送配置信息，也可以通过中继向终端发送配置信息，其具体方式取决于终端的位置，在本公开中不予限制。
应当理解，在上述描述中阐明了，基站可以配置中继如何发送测量参考信号，中继可以基于基站的配置发送测量参考信号，终端可以基于基站的配置测量中继发出的波束(即测量参考信号)，换言之，基站可以向中继和终端下达命令(即配置信息)，基于此，中继去发送波束，终端去测量波束。例如，测量参考信号配置信息包括天线端口信息、时频资源信息、以及测量参考信号序列的产生参数中的至少一项，中继可以基于该配置信息执行在哪个端口上发送波束、占用了多少时频资源、如何发送波束，即，中继可以在指定的时频资源上，使用指定的天线端口和参考信号序列发送测量参考信号。对应地，终端可以基于该配置执行在哪个端口上接收波束、在哪些子载波上测量、如何进行波束测量。换言之，该配置信息对于中继和终端而言，内容是相同的，目的是不同的。
S204，接收终端上报的波束测量结果。
在本公开的实施例中，终端能够根据基站发送的测量参考信号配置信息对从中继接收到的测量参考信号进行测量，从而获得测量结果并上报至基站。

在本公开的实施例中，基于终端上报的测量结果，基站可以生成波束指示信息，其中，波束指示信息可以指示一个波束，也可以指示两个及两个以上波束及各个波束的加权系数。
例如，基站可以向中继发送波束指示信息，该波束指示信息包括一个或多个配置波束的索引信息，其可以通过配置波束的索引进行指示，或者通过配置波束所关联的测量参考信号进行指示。当波束指示信息指示两个及两个以上波束时，波束指示信息中还包括每个波束所对应的加权系数。
再例如，基站可以向终端发送波束指示信息，该波束指示信息包括一个或多个配置波束的索引信息，其可以通过配置波束的索引进行指示，或者通过配置波束所关联的测量参考信号进行指示。当波束指示信息指示两个及两个以上波束时，波束指示信息中还包括每个波束所对应的加权系数。
应当理解的是，在指示阶段，基站对中继的指示与基站对终端的指示可以是相互独立且隔离。本公开中，基站具有配置和决策能力，中继和终端可以根据基站的配置进行波束的收发，不再进行选择和判断，但本公开并不约束中继和终端具有一定的决策能力。
综上，根据本公开实施例提供的基于波束配置的通信方法，基站通过配置中继与终端之间的配置波束，并向中继和/或终端发送配置波束的配置信息，使得终端能够进行波束测量并上报测量结果，基站能够基于终端上报的波束测量结果，生成并发送波束指示信息，从而辅助第二网络设备和/或终端生成发送波束或者接收波束，因此，实现了波束调整和赋形，扩大了通信方法的适用场景，增强了通信系统的灵活性和可配置性，为多种业务类型和复杂通信场景下的传输需求提供有效支撑。
