  • 5G (fifth generation mobile communication technology) systems can provide greater bandwidth and higher data rates, and can support more types of terminals and vertical services. For this reason, the frequency band range/working bandwidth supported by the 5G system is significantly larger than that of the 2G, 3G and 4G systems, and the 5G system supports higher carrier frequencies. For example, 5G systems can be deployed in the millimeter wave band.

In other words, traditional radio frequency transponders cannot interact with other devices to amplify/enhance target signals (e.g. base stations/terminal equipment, etc.). Specifically, in terms of reception, traditional radio frequency transponders do not support measurement/demodulation/decoding of the forwarded signal, nor do they receive signals other than the forwarded signal. In terms of transmission, traditional RF transponders only amplify and forward signals, and do not support generating signals and transmitting self-generated signals.

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。
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,射频转发器只是将接收到的所有信号直接放大并转发。
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放大/增强目标信号(e.g.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转发信号进行测量/解调/解码,也不接收转发信号之外的信号。在发送方面,传统射频转发器仅放大并转发信号,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,放大增益、天线方向等)通常是人工设置或调整的,而不能自适应和/或动态调整。例如,射频转发器的天线方向通常在初始安装的时候由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。再例如,射频转发器的放大增益也在初始安装时进行设置和调整,以尽可能达到预期的覆盖增强效果。
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,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。这样的射频转发器配置在5G系统中,一方面,射频转发器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、宽度的动态变化可能不匹配,导致放大或增强目标信号的性能及效果不显著,另一方面,采用较宽的发送波束也可能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,导致整个系统的噪声和干扰水平的升高,进而降低网络吞吐量。
为了解决上述问题中的一个或多个,一方面,转发器可以根据基站的指示调整终端侧的波束方向和/或宽度。另一方面,为了能够确定和终端设备匹配的波束,和/或支持终端设备进行波束校准,转发器可以根据基站的指示周期性或半持续地对终端侧波束进行波束扫描或重复。由此,可以尽可能放大/增强目标信号,同时减小对其他设备的干扰。
而为了实现上述方式,需要转发器具有通信功能。本申请实施例提供一种网络设备和转发器间的通信方法及装置,能够支持转发器接收(例如包括检测序列、解调、解扰、解码以及解读等中的至少一个)网络设备发送的信息,和/或,向网络设备发送(例如包括生成信息、生成序列、加扰、编码、调制、映射到时频资源等中的至少一个)信息。

图2是当前系统中使用波束进行通信的一示意图。如图2所示,在当前的使用转发器的通信系统中,转发器使用较宽的波束,且天线的方向固定,从而,转发器收发天线的波束方向、波束宽度和作为网络设备的gNB以及作为终端设备的的UE的收发天线的波束方向、宽度的动态变化可能不匹配,导致放大或增强目标信号的性能及效果不显著,另一方面,由于转发器采用较宽的发送波束,也可能对较大范围内的其它设备(例如,网络设备或终端设备)造成明显干扰,导致整个系统的噪声和干扰水平的升高,进而降低网络吞吐量。
图3是本申请实施例的一个使用场景的一示意图。如图3所示,在一个作为网络设备的gNB101下面,部署有多个转发器,即第一转发器103-1和第二转发器103-2, 第一转发器103-1和第二转发器103-2服务于不同的UE。
在该场景下,网络设备与转发器之间的信息发送和/或信息接收可能需要是转发器特定的或者是多个转发器共用的。例如,需要支持以下通信方式:
网络设备发送的信息(例如控制信息等)可以针对一个转发器(也就是说,该信息是一个转发器特定的(repeater specific/dedicated)或多个转发器(也就是说,该信息是多个转发器共用的(group common)。为便于以下描述,这里将一个信息针对的转发称为目标转发器,目标转发器能够接收并确定该信息的全部或部分是针对它的,和/或,能够确定哪部分信息是针对它的。而非目标转发器不能接收该信息,或者接收并能够确定该信息不是针对它的。再例如,一个转发器向网络设备发送信息(例如针对控制信息的响应信息、测量上报信息、触发信息,请求信息、确认信息(例如ACK/NACK)等),该网络设备能够接收并确定该信息是来自该转发器的。
例如,如图3所示,gNB101发送的信息可以针对第二转发器103-2,第二转发器103-2能够接收并确定该信息的全部或部分是针对第二转发器103-2的,和/或,能够确定哪部分信息是针对第二转发器103-2的。而第一转发器103-1不能接收该信息,或者接收(例如包括检测序列、解调、解扰、解码以及解读等中的至少一个)并能够确定该信息不是针对第一转发器103-1的。再例如,gNB101发送的信息可以针对第一转发器103-1和第二转发器103-2,第一转发器103-1和第二转发器103-2都能接收该信息,并且能够确定各自对应其中哪部分信息。再例如,第二转发器103-2向gNB101发送信息,gNB101能够接收并确定该信息是来自第二转发器103-2的。
而当前的机制无法支持上述通信方式。
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。
实施例1
