Description

转发器、网络设备及其通信方法 技术领域
本申请涉及通信领域。
背景技术
与传统的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系统的部署频率通常明显高于3G和4G系统。例如，5G系统可以部署在毫米波波段。
然而，承载频率越高，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。
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
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)放大和转发终端设备与网络设备之间的通信信号，是比较常用的部署手段。射频转发器在3G系统和4G系统的实际部署中具有较为广泛的应用。通常来说，射频转发器是一种在射频域放大和转发网络设备与终端设备往来信号的设备。
发明人发现，针对5G系统在部署中遇到的覆盖问题，采用射频转发器进行覆盖增强是可行的解决方案之一。但是，传统转发器不具备与网络设备通信的能力，不能从网络设备处直接获得上下行配置的相关信息。因此，这样的转发器配置在5G系统中，虽然能够帮助增强信号强度，但是不够灵活而无法应对复杂的环境变化，进而无法达到在3G系统和4G系统中部署相同射频转发器的同等效果。
针对上述问题的至少之一，本申请实施例提供了一种转发器、网络设备及其通信方法。转发器具有与网络设备通信的能力。转发器通过接收网络的指示信息，与网络设备进行通信或者对网络设备与第三设备之间的信号进行转发。采用本申请的实施方法，可以根据网络实时情况通过与转发器进行通信(进行上下行(UL/DL)信号和/或信息传输)， 对转发器的转发进行及时、适当的调整。本申请实施例的转发器能够更好地加强信号覆盖并应对环境变化，由此能够提高整个网络的传输效率。
根据本申请实施例的一方面，提供一种转发器的通信方法，包括：
转发器接收网络设备发送的第一指示信息；
其中，所述第一指示信息用于指示一组时间单位；所述一组时间单位中的第一时间单位能够被所述转发器用于向所述网络设备发送由所述转发器生成的第一信号，所述一组时间单位中的第二时间单位能够被所述转发器用于向所述网络设备发送不由所述转发器生成的第二信号。
根据本申请实施例的另一方面，提供一种转发器，包括：
接收部，其接收网络设备发送的第一指示信息；
其中，所述第一指示信息用于指示一组时间单位；所述一组时间单位中的第一时间单位能够被所述转发器用于向所述网络设备发送由所述转发器生成的第一信号，所述一组时间单位中的第二时间单位能够被所述转发器用于向所述网络设备发送不由所述转发器生成的第二信号。
根据本申请实施例的另一方面，提供一种网络设备的通信方法，包括：
网络设备向转发器发送第一指示信息；
其中，所述第一指示信息用于指示一组时间单位，所述一组时间单位中的第一时间单位能够被所述转发器用于向所述网络设备发送由所述转发器生成的第一信号，所述一组时间单位中的第二时间单位能够被所述转发器用于向所述网络设备发送不由所述转发器生成的第二信号。
根据本申请实施例的另一方面，提供一种网络设备，包括：
发送部，其向转发器发送第一指示信息；
其中，所述第一指示信息用于指示一组时间单位，所述一组时间单位中的第一时间单位能够被所述转发器用于向所述网络设备发送由所述转发器生成的第一信号，所述一组时间单位中的第二时间单位能够被所述转发器用于向所述网络设备发送不由所述转发器生成的第二信号。
根据本申请实施例的另一方面，提供一种通信系统，包括网络设备和终端设备，所述通信系统还包括：
网络设备，其发送第一指示信息，所述第一指示信息用于指示一组时间单位；
转发器，其接收所述第一指示信息；其中，所述一组时间单位中的第一时间单位能 够被所述转发器用于向所述网络设备发送由所述转发器生成的第一信号，所述一组时间单位中的第二时间单位能够被所述转发器用于向所述网络设备发送不由所述转发器生成的第二信号。
本申请实施例的有益效果之一在于：转发器和网络设备之间的通信和转发的时间单位可以由网络设备配置，由此能够根据网络实时情况通过与转发器的通信对转发器的转发进行及时的调整，可以更好地加强信号覆盖并应对环境变化，从而能够提高整个网络的传输效率。

在本申请实施例中，术语“用户设备”(UE，User Equipment)例如是指通过网络设备接入通信网络并接收网络服务的设备，也可以称为“终端设备”(TE，Terminal Equipment)。终端设备可以是固定的或移动的，并且也可以称为移动台(MS，Mobile Station)、终端、用户、用户台(SS，Subscriber Station)、接入终端(AT，Access Terminal)、站，等等。

图1是本申请实施例的应用场景的示意图，如图1所示，为了方便说明，以一个网络设备(例如5G基站gNB)101、一个转发器(Repeater)102和一个终端设备(UE) 103为例进行说明，本申请不限于此。如图1所示，终端设备103与网络设备101建立连接、与其通信。为了增加通信质量，终端设备103与网络设备101之间的信号经由转发器102进行转发。网络设备101，终端设备103与转发器102之间的信号交互均采用基于波束的接收和发送方法。
如图1所示，网络设备101可以具有第一小区/载波，网络设备101、转发器102和终端设备103可以在该第一小区进行转发/通信；但本申请不限于此，例如网络设备101还可以具有其他小区/载波。

图1中以转发器可以转发网络设备和终端设备之间的信号为例进行说明，但本申请不限于此。例如，转发器可以作为第二设备，在第一设备和第三设备之间进行信号转发，并能够与第一设备和/或第三设备直接进行通信；第一设备至第三设备可以是前述的网络中的任意设备。以下的实施例中，以第一设备为网络设备，第三设备为终端设备为例进行说明。
图2是TDD转发器的一示意图。如图2所示，时分双工(TDD，Time Division Duplex)转发器有两条通路。转发器的两侧天线分别对准网络设备和需要被服务的终端设备可能存在的区域，通过时分方式在网络设备和终端设备之间转发信号。
传统转发器在转发过程中，不对转发信号进行解调/解码。传统转发器的天线方向基本是固定的，通常在初始安装的时候人工进行设置和调整，以使得网络设备侧的天线指向网络设备来波方向，终端设备侧的天线指向需要增强部署的地方。在传统转发器工作的过程中，天线方向不发生改变。此外，传统转发器不具备通信功能，不能够和网络设备进行信息交互，因此也不支持网络设备对其进行自适应和/或较为动态的配置。
相比于3G和4G系统，部署在较高频段和毫米波频段的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，有向天线成为网络设备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。
特别是毫米波波段频率高、小波长的特点，更利于在网络设备和终端设备中设置包含较多阵子的天线面板。天线阵子个数的增加有助于更为精准的波束赋形，即更容易形成窄波束。窄波束汇聚能量有助于增强信号，并同时减小对其它设备的干扰。另一方面， 由于窄波束的指向精准，对信道测量和波束管理的要求非常高，因此5G系统支持较为复杂但精准的信道测量、天线校准和波束管理方案，网络设备可以通过这些方案有效而精准地控制终端设备的接收波束和发送波束，以达到更好的通信效果。
传统转发器不具备与网络设备通信的能力，转发器需要自行探测/确定网络中相关的上下行配置(TDD UL/DL config)。而后，在网络的下行时间单位，转发器切换至下行转发位置，即从网络设备侧接收信号，经过放大等处理后，从终端设备侧将信号发送出去；在网络的上行时间单位，转发器切换至上行转发位置，即从终端设备侧接收信号，经过放大等处理后，从网络设备侧将信号发送出去。
因此，传统转发器虽然能够帮助增强信号强度，但是不够灵活而无法应对复杂的环境变化，进而降低整个网络的吞吐量。为了使得转发器的转发能够更为灵活以适应5G网络的特点，网络需要对转发器进行协助，并能够根据网络实时情况对转发器的转发进行配置；而转发器需要具有与网络设备通信的能力，能够从网络设备处接收辅助信息和/或配置信息等(例如TDD UL DL配置，发送/接收空间滤波器的指示等)，也能进行必要的反馈和上报。
发明人在对相关领域进行研究的过程中发现，转发器与网络设备进行通信，需要生成发送给网络设备的发送信号，或者，对网络设备发送过来的信号进行处理。如何将转发器转发和通信功能复用在一起，可能是实现具有通信功能转发器的一个关键点，也是实现所述具有与网络通信功能的转发器亟需解决的问题。
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。
在本申请实施例中，波束(beam)也可以表述为波瓣、参考信号(RS)、传输配置指示(TCI，transmission configuration indication)、空域滤波器(spatial domain filter)等。或者，也可以表述为波束索引、波瓣索引、参考信号索引、传输配置指示索引、空域滤波器索引等。上述参考信号例如为信道状态信息参考信号(CSI-RS)、探测参考信号(SRS)、供转发器使用的RS、由转发器发送的RS等。上述TCI也可以表述为TCI状态(state)。
在本申请实施例中，转发器还可以表述为直放站、射频转发器、中继器、射频中继器；或者也可以表述为直放站节点、转发器节点、中继器节点；或者还可以表述为智能直放站、智能转发器、智能中继器、智能直放站节点、智能转发器节点、智能中继器节点，等等，本申请不限于此。
在本申请实施例中，网络设备可以是终端设备的服务小区的设备，也可以是转发器所在的小区的设备，还可以是转发器的服务小区的设备，也可以是转发器的父节点(Parent node)，本申请对该转发器的名称不做限制，只要能实现上述功能的设备，都包含于本申请的转发器的范围内。
第一方面的实施例
本申请实施例提供一种转发器的通信方法，从转发器一侧进行说明。
图3是本申请实施例的转发器的通信方法的一示意图，如图3所示，该方法包括：
301，转发器接收网络设备发送的第一指示信息；
其中，所述第一指示信息用于指示一组时间单位，所述一组时间单位中的第一时间单位能够被所述转发器用于(available for)向所述网络设备发送由所述转发器生成的第一信号，所述一组时间单位中的第二时间单位能够被所述转发器用于(available for)向所述网络设备发送不由所述转发器生成的第二信号。
在一些实施例中，第一指示信息可以是上层信令也可以是物理层信令，但本申请不限于此。上层信令例如可以是无线资源控制(RRC，Radio Resource Control)信令或者介质访问控制(MAC，Media Access Control)信令。物理层信令例如可以是物理下行控制信道(PDCCH，Physical Downlink Control Channel)或下行控制信息(DCI，Downlink Control Information)，也可以称为动态信令。
在一些实施例中，第一指示信息可以由一个或多个信令来配置和/或指示。可以是在某一个时间由网络设备配置和/或指示给转发器，也可以是在多个时间分别由网络设备通过静态信令、半静态信令、动态信令中的一种或多种配置和/或指示给转发器。
例如，第一指示信息可以由网络设备通过公共信令(common RRC信令)广播给该转发器。该公共信令中至少配置第一时间单位(例如U1)和/或第二时间单位(例如U2)；此外，该公共信令还可以配置其他时间单位，例如用于下行的时间单位(D)等等。
转发器可以使用该公共信令中配置的第一时间单位(例如U1)向网络设备发送第一信号，使用该公共信令中配置的第二时间单位(例如U2)向网络设备发送第二信号。
再例如，第一指示信息可以由网络设备通过公共信令(common RRC信令)和专用信令(dedicated RRC信令)配置给该转发器。该公共信令中至少配置第一时间单位(例如U1)和/或第二时间单位(例如U2)；此外，该公共信令还可以配置其他时间单位，例如用于下行的时间单位(D)等。该专用信令可以将其他时间单位再配置为第一时间 单位(例如U1)和/或第二时间单位(例如U2)等。
转发器可以使用该公共信令和专用信令共同配置的第一时间单位(例如U1)向网络设备发送第一信号，使用该公共信令和专用信令共同配置的第二时间单位(例如U2)向网络设备发送第二信号。
再例如，第一指示信息可以由网络设备通过公共信令和专用信令配置、再通过动态信令(例如PDCCH)指示给该转发器。该公共信令中至少配置第一时间单位(例如U1)和/或第二时间单位(例如U2)；此外，该公共信令还可以配置其他时间单位，例如用于下行的时间单位(D)等。该专用信令可以将其它时间单位再配置为第一时间单位(例如U1)和/或第二时间单位(例如U2)等，该动态信令可以将其它时间单位再配置为第一时间单位(例如U1)和/或第二时间单位(例如U2)等。
转发器可以使用该公共信令、专用信令和动态信令共同配置和指示的第一时间单位(例如U1)向网络设备发送第一信号，使用该公共信令、专用信令和动态信令共同配置和指示的第二时间单位(例如U2)向网络设备发送第二信号。
以上仅示意性对第一指示信息进行了说明，但本申请不限于此。
由此，转发器和网络设备之间的上行通信和上行转发的时间单位可以由网络设备配置，能够根据网络实时情况进行上行传输，从而可以更好地加强信号覆盖并应对环境变化，由此能够提高整个网络的传输效率。
在一些实施例中，可选地，如图3所示，该方法还可以包括：
302，转发器在第一时间单位向网络设备发送第一信号，和/或，在第二时间单位向网络设备发送第二信号。
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。
由此，上行通信与上行转发被时分复用，对设备的要求较低，有助于降低转发器的实现成本。实现成本的降低有助于未来转发器设备在网络部署中的应用，也有利于以较小的代价增强网络部署(例如提高网络覆盖)。
在一些实施例中，网络设备向转发器指示和/或配置一组时间单位的周期，和/或，向转发器指示和/或配置一组时间单位所对应的子载波间隔。关于周期和/或子载波间隔的配置和指示，可以是与第一指示信息一起进行的，也可以是独立于第一指示信息而分 别进行的。
在一些实施例中，所述一组时间单位中的时间单位是符号(symbol)、时隙(slot)、子帧(subframe)中的至少一种。例如可以是符号(symbol)这一种，也可以是时隙(slot)这一种，还可以是同时包括符号(symbol)和时隙(slot)这两种，等等，本申请不限于此。
