Description

一种通信方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
与传统的2G(第二代移动通信技术)、3G(第三代移动通信技术)、4G(第四代移动通信技术)系统相比，5G(第五代移动通信技术)系统能够提供更大的带宽以及更高的数据率，并且能够支持更多类型的终端和垂直业务。为此，5G系统支持的频带范围/工作带宽明显大于2G，3G和4G系统，并且，5G系统支持更高的载波频率。例如，5G系统可以部署在毫米波波段。
然而，载波频率越高，信号在传输过程中遇到的衰落越严重。因此，在5G系统的实际部署中，特别是在毫米波段，如何更好的增强小区覆盖，成为亟待解决的问题。
为了更好的解决蜂窝移动通信系统在实际部署中的覆盖问题，采用射频转发器(RF Relay/Repeater)放大和转发设备之间的信号，是比较常用的部署手段。射频转发器在2G系统，3G系统和4G系统的实际部署中具有较为广泛的应用，其优点在于低成本，易部署，且不会增加过多时延。通常来说，射频转发器是一种在射频域放大(amplify)和转发(forward)设备往来信号的设备。也就是说，射频转发器是一种非再生类型的中继节点，它们只是将接收到的所有信号直接放大并转发。
另外，传统射频转发器不具备通信功能。也就是说，传统射频转发器不能够和其他设备(例如基站/终端设备等)进行信息交互。具体地，在接收方面，传统射频转发器不支持对接收到的信号进行测量/解调/解码等。在发送方面，传统射频转发器仅放大并转发接收到的射频信号，不支持生成信号和发送自身生成的信号。
因此，传统射频转发器的工作相关配置(例如，天线方向(波束方向和/或宽度(或者说大小))、转发方向、开关状态、放大增益等)不受控于网络，通常是人工设置或调整的。例如，天线方向通常在初始安装的时候人工进行设置和调整，以使得基站侧的天线指向基站来波方向，终端侧的天线指向需要增强部署的地方。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申 请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，针对5G系统在部署中遇到的覆盖问题，采用传统射频转发器进行覆盖增强是可行的解决方案之一。但是，由于传统射频转发器的工作相关配置(例如，天线方向(波束方向和/或宽度(或者说大小))、转发方向、开关状态、放大增益等)不受控于网络，一方面，其放大转发目标信号的效果可能不理想，另一方面，其可能对网络中其他设备造成明显干扰，提升系统的噪声和干扰水平，进而降低网络吞吐量。
以天线方向为例，相比于2G、3G和4G系统，5G系统采用了更为高级和复杂的MIMO(多进多出)技术。在5G系统中，尤其针对较高的载波频率，有向天线成为基站与终端设备的基本部件，基于波束赋形(Beam forming)技术发送和接收信号是5G系统中基本的信号传输方式。基站和终端设备的(模拟)波束方向、宽度(大小)等可能由于位置变化等因素动态变化(也就是波束切换)。然而，传统射频转发器的天线不可动态地调整方向、波束较宽，其收发天线的波束方向、波束宽度不能灵活匹配基站和终端设备的位置以及收发天线的波束方向、宽度的动态变化。
图1是部署于5G系统中的射频转发器的收发天线的一个示例，如图1所示，这样的射频转发器配置在5G系统中，一方面，其可能由于其收发天线的波束方向、波束宽度和基站和终端设备的收发天线的波束方向、宽度的动态变化不匹配，放大/增强目标信号的性能/效果不显著，另一方面，其可能由于采用较宽的发送波束也对较大范围内的其它设备(例如基站或者终端设备)造成明显干扰，提升整个系统的噪声和干扰水平，进而降低网络吞吐量。
为了解决上述问题至少之一，网络(基站)可以对射频转发器的工作相关配置进行一些控制。而为了实现网络对射频转发器的工作相关配置的控制，需要支持网络(基站)和射频转发器之间的信息交互，使得射频转发器可以根据网络(基站)的指示设置和/或调整工作相关配置，例如天线方向(波束方向和/或宽度(或者说大小))、转发方向、开关状态、放大增益等。也就是说，射频转发器具有通信功能，以接收(解调/测量/解码/解读等)网络(基站)的发送的信息，和/或，向网络(基站)发送信息。
然而，关于如何支持上述信息交互以及射频转发器如何在支持上述信息交互的情况下工作，目前还没有具体的方法。
针对上述问题，本申请实施例提供了一种通信方法、装置和系统，以支持网络设备(基站)和射频转发器之间的信息交互，以使得射频转发器在支持上述信息交互的情况下工作。
在本申请实施例中，涉及射频转发器在支持和网络之间的信息交互的情况下的波束指示。
根据本申请实施例的一方面，提供一种通信装置，配置于转发器，所述装置包括第一模块和第一模块，其中，
所述第一模块获取第一波束指示，所述第一波束指示至少用于所述第一模块在第一频带接收来自第一网络设备的信号，和/或，所述转发器的第一模块获取第二波束指示，所述第二波束指示至少用于所述第一模块在第一频带向所述第一网络设备发送信号；
所述第一模块获取第三波束指示，所述第三波束指示至少用于所述转发器的第二模块在第二频带接收来自第二网络设备的第三信号，所述第三信号用于被转发；和/或，所述第一模块获取第四波束指示，所述第四波束指示至少用于所述第二模块在第二频带将来自终端设备的、经过处理的第四信号转发给所述第二网络设备；
所述第一频带和所述第二频带在频域不重叠。
本申请实施例的有益效果之一在于：根据本申请实施例，通过获取第一波束指示和/或第二波束指示，能够实现转发器与基站(第一网络设备)之间的通信(信息交互)，此外，通过获取第三波束指示和/或第四波束指示，能够实现转发器对基站(第二网络设备)和终端设备之间的信号的转发。

为了使本申请实施例易于理解，下面对本申请实施例涉及的术语和场景进行举例说明。
在本申请实施例中，具有前述通信功能的射频转发器可以称为NCR(network-controlled repeater)或SR(smart repeater)等，不限于此。
图2是该NCR的一个示例的示意图，如图2所示，该NCR 21在功能上分为NCR-MT(Mobile Termination)211和NCR-Fwd(Forwarding)212两部分。该NCR-MT211用于通过控制链路(C-link，Control link)与gNB 22进行通信，以进行信息交互，交互的信息例如包括侧控制信息(side control information)，该控制链路基于NR的Uu接口，并且，该侧控制信息至少用于对NCR-Fwd 212的控制。此外，该NCR-Fwd212用于通过回程链路(B-link，Backhaul link)和接入链路(A-link，Access link) 在gNB 22和UE 23之间执行UL(上行)和/或DL(下行)射频信号(RF signal)放大和转发(amplify-and-forwarding)，该NCR-Fwd 212的行为根据从gNB 22接收到的侧控制信息和/或其他信息进行控制。
在上述示例中，gNB 22和UE 23的数量可以分别是一个或多个。其中，与NCR-MT进行通信的gNB和被NCR-Fwd放大转发相应射频信号的gNB可以有交集，也可以没有交集。
当前，NR支持较大的频率范围。至NR Rel-17，定义了多个频率范围，例如，FR1和FR2。其中，FR2还可以进一步分为FR2-1和FR2-2。
由于高频(例如FR2)的覆盖范围较小，如果采用高频(例如FR2)保证基础覆盖(例如，支持UE的初始接入，建立/重建RRC连接等)，意味着需要较高密度部署大量站点，成本较高。因而，在目前的实际部署中，部分运营商采用低频(例如FR1)保证基础覆盖；而高频(例如FR2)则作为热点覆盖，用于流量卸载(traffic off-load)或者说容量增强，不用于保证基础覆盖(例如，不支持UE的初始接入，建立/重建RRC连接等)。
同时，由于高频的覆盖范围小且信号容易被阻挡，NCR可能仅用于放大并转发高频的信号，而不放大转发低频的信号。
图3是本申请实施例的实施场景的一个示例的示意图，如图3所示，NCR 31通过控制链路(C-link)与第一gNB 32进行通信，以实现信息交互，其中，控制链路基于NR的Uu接口。另外，NCR 31还可以通过回程链路(Backhaul link)和接入链路(Access link)在第二gNB 34和UE 33之间执行UL(上行)/DL(下行)射频信号放大和转发，例如可以根据从第一gNB 32收到的信息进行放大和转发等操作。
此外，在图3的场景中，NCR 31在高频(例如FR2)进行第二gNB 34和UE 33之间的信号的放大和转发操作，而在低频(例如FR1)进行与第一gNB 32的通信操作，但本申请不限于此，图3的场景只是举例说明，例如，NCR 31还可以在低频(例如FR1)进行第一gNB 32和UE 33之间的信号的放大和转发操作，和/或在在高频(例如FR2)进行与第一gNB 32的通信操作；再例如，第二gNB 34和第一gNB 32也可以相同，等。
在图3的示例中，第一gNB 32和第二gNB 34可以是相同的网络设备，也可以是不同的网络设备，关于网络设备的含义已经在前面做了说明，此处不再赘述。
图4是NCR的链路和频率范围的关系的示意图，如图4所示，控制链路涉及的频率范围为FR1或者FR1和FR2，也就是说，NCR-MT可以在FR1或者FR1和FR2接收和/或发送物理信号；回程链路和接入链路涉及的频率范围为FR2，也就是说，NCR-Fwd在FR2放大转发射频信号。
下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本申请的限制。
第一方面的实施例
本申请实施例提供一种通信方法。
图5是本申请实施例的通信方法的一示意图，如图5所示，该方法包括：
501：转发器的第一模块获取第一波束指示，所述第一波束指示至少用于所述第一模块在第一频带接收来自第一网络设备的信号，和/或，所述转发器的第一模块获取第二波束指示，所述第二波束指示至少用于所述第一模块在第一频带向所述第一网络设备发送信号；
502：所述第一模块获取第三波束指示，所述第三波束指示至少用于所述转发器的第二模块在第二频带接收来自第二网络设备的第三信号，所述第三信号用于被转发；和/或，所述第一模块获取第四波束指示，所述第四波束指示至少用于所述第二模块在第二频带将来自终端设备的、经过处理的第四信号转发给所述第二网络设备；所述第一频带和所述第二频带在频域不重叠。
在本申请实施例中，第一波束指示和/或第二波束指示用于转发器的第一模块在第一频带与网络设备(第一网络设备)进行通信；第三波束指示和/或第四波束指示用于转发器的第二模块在第二频带对网络设备(第二网络设备)和终端设备之间的信号(射频信号)进行转发。由此，能够实现转发器在第一频带与基站(第一网络设备)之间的通信(信息交互)，并且转发器在第二频带对基站(第二网络设备)和终端设备之间的信号的转发。此外，第一频带和第二频带在频域上不重叠，转发器可以在不同频带分别用于基础覆盖和热点覆盖的网络部署场景中工作。例如，第一频带在低频，用于基础覆盖，第二频带在高频，用于热点覆盖，转发器的第一模块在第一频带与网络通信，网络通过侧控制信息(side control information)和/或其他信息控制转发器的第二模块在第二频带如何/是否放大转发射频信号，以扩大热点覆盖范围。
在上述实施例中，以转发器在第二频带进行信号转发为例进行说明，但本申请不限于此，转发器还可以在第一频带进行信号转发，其中，在第一频带进行信号转发的操作可以合并到第二模块中，也可以通过独立于第二模块的其他模块(第三模块)实现。例如，转发器包括两个转发模块(NCR-Fwd)，第一转发模块用于在第一频带进行信号转发，第二转发模块用于在第二频带进行信号转发，来自网络设备的侧控制信息和/或其他信息用于控制转发器的第一转发模块和/或第二转发模块。也就是说，第二模块包括第一转发模块和第二转发模块；或者，第二模块包括第二转发模块，而独立于第二模块的其他模块(第三模块)包括第一转发模块。
在一些实施例中，第三模块仅用于放大和转发射频信号。
