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。
传统射频转发器在转发过程中，不对转发信号进行解调/解码。传统射频转发器的天线方向是固定的。传统射频转发器的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。在传统射频转发器工作的过程中，天线方向不发生改变。此外，传统射频转发器不具备通信功能，不能够和基站进行信息交互，因此也不支持基站对其进行自适应和/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。
特别是毫米波波段频率高、小波长的特点更利于在基站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，基站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。
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，传统射频转发器的天线不可动态地调整方向、波束较宽。这样的射频转发器配置在5G系统中，虽然能够帮助增强信号强度，但也会由于发送波束较宽而对周围的其它基站或者终端设备造成比较明显的干扰，进而因为新干扰的增加而降低整个网络的吞吐量。
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。转发器通过与网络设备通信，可以接收网络设备根据网络实时情况做出的针对转发的指示或配置(例如，波束指示或配置，转发带宽等)，并根据该指示或配置来转发信号。采用本申请的实施方案中的转发器能够更好地加强信号覆盖并减小对周围其它设备的干扰，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：
转发器使用预定义的波束或者网络设备指示或配置的波束转发来自所述网络设备的信号，和/或，所述转发器使用预定义的波束或者所述网络设备指示或配置的波束向所述网络设备转发信号。
根据本申请实施例的另一方面，提供一种转发器，包括：
转发模块，其使用预定义的波束或者网络设备指示或配置的波束转发来自所述网络设备的信号，和/或，使用预定义的波束或者所述网络设备指示或配置的波束向所述网络设备转发信号。
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用于指示或配置所述转发器的波束的配置信息；以及
所述网络设备发送经由所述转发器转发的信号，和/或，接收经由所述转发器转发的信号。

配置模块，其向转发器发送用于指示或配置所述转发器的波束的配置信息；以及
通信模块，其发送经由所述转发器转发的信号，和/或，接收经由所述转发器转发的信号。
根据本申请实施例的另一方面，提供一种第三设备的通信方法，包括：
第三设备使用预定义的波束或者网络设备指示或配置的波束，向网络设备发送经由转发器转发的信号，和/或，接收经由所述转发器转发的来自所述网络设备的信号。
根据本申请实施例的另一方面，提供一种第三设备，包括：
通信模块，其使用预定义的波束或者网络设备指示或配置的波束，向网络设备发送经由转发器转发的信号，和/或，接收经由所述转发器转发的来自所述网络设备的信号。
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，所述通信系统还包括：
转发器，其使用预定义的波束或者所述网络设备指示或配置的波束转发来自所述网络设备的信号，和/或，使用预定义的波束或者所述网络设备指示或配置的波束向所述网络设备转发信号。
本申请实施例的有益效果之一在于：转发器通过预定义的波束或者网络设备指示或配置的波束来转发信号，从而能够实现更好的信号覆盖以及减小对周围其它设备的干扰，由此能够提高整个网络的传输效率。
