Description

无线通信系统中的电子设备、方法和计算机可读存储介质
本申请要求于2017年11月29日提交中国专利局、申请号为201711227563.4、发明名称为“无线通信系统中的电子设备、方法和计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明的实施例总体上涉及无线通信领域，具体地涉及无线通信系统中的作为主发送设备的电子设备和作为辅发送设备的电子设备、由无线通信系统中的作为主发送设备的电子设备执行的无线通信方法和由无线通信系统中的作为辅发送设备的电子设备执行的无线通信方法、以及计算机可读存储介质。
背景技术
波束赋形是一种基于天线阵列的信号预处理技术，波束赋形通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束，从而能够获得明显的阵列增益。因此，波束赋形技术在扩大覆盖范围、改善边缘吞吐量以及干扰抑止等方面都有很大的优势。在未来的通信系统中，波束赋形是一项能够增加频谱和功率的利用率的重要技术。
在使用波束赋形的无线通信系统中，存在需要多个发送设备同时向接收设备发送波束信号的场景，也就是说，不同的发送设备需要同时向接收设备所在的区域发送波束信号，即波束间的同步。在无线通信系统中传统的同步仅仅涉及不同的发送设备在时间方面和频率方面的同步，并未涉及在波束方面的同步。
因此，有必要提出一种方案，以实现不同的发送设备同时向接收设备所在的区域发送波束信号。
发明内容
这个部分提供了本公开的一般概要，而不是其全部范围或其全部特 征的全面披露。

根据本公开的另一方面，提供了一种用作无线通信系统中的辅发送设备的电子设备，包括处理电路，被配置为：从所述无线通信系统中的主发送设备接收与用于特定时间期间的波束赋形的区域相关联的信息；以及在所述特定时间期间生成波束信号并向所述区域发送所述波束信号，其中，在所述特定时间期间所述主发送设备与所述电子设备同时生成波束信号并向所述区域发送所述波束信号。

根据本公开的另一方面，提供了一种由无线通信系统中的作为辅发送设备的电子设备执行的无线通信方法，包括：从所述无线通信系统中的主发送设备接收与用于特定时间期间的波束赋形的区域相关联的信息；以及在所述特定时间期间生成波束信号并向所述区域发送所述波束信号，其中，在所述特定时间期间所述主发送设备与所述电子设备同时生成波束信号并向所述区域发送所述波束信号。
根据本公开的另一方面，提供了一种计算机可读存储介质，包括可执行计算机指令，所述可执行计算机指令当被计算机执行时使得所述计算 机执行根据本公开所述的无线通信方法。
使用根据本公开的无线通信系统中的电子设备、由无线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质，主发送设备可以确定用于波束赋形的区域并将与该区域相关联的信息发送至辅发送设备，从而使得主发送设备和辅发送设备同时向该区域发送波束信号，以实现波束间的同步。

值得注意的是，图1中仅示出了无线通信系统包括一个主发送设备和两个辅发送设备的场景，无线通信系统还可以包括一个或多于两个的辅发送设备。也就是说，无线通信系统中包括一个主发送设备以及一个或多个辅发送设备，即无线通信系统包括多个发送设备。进一步，无线通信系统还可以包括多个用户设备。此外，图1仅示出了用户设备是无人机的情形，用户设备还可以是其它类型的用户侧设备。也就是说，本公开适用于以下场景：需要多个发送设备同时向用户设备所在的区域执行波束扫描。此外，本公开的实施例优选地可以用于高频段的场景中，例如NR(New Radio，新无线)系统中。
本公开针对这样的场景提出了一种无线通信系统中的电子设备、由无线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质，以实现不同的发送设备同时向接收设备所在的区域发送波束信号。

这里，电子设备200的各个单元都可以包括在处理电路中。需要说明的是，电子设备200既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，确定单元210可以确定用于特定时间期间的波束赋形的区域。这里，特定时间期间可以表示主发送设备与辅发送设备提前约定好的一段时间期间。
根据本公开的实施例，通信单元220可以将与确定单元210确定的区域相关联的信息发送至无线通信系统中的一个或多个辅发送设备，以用于一个或多个辅发送设备在特定时间期间生成波束信号并向该区域发送波束信号。这里，通信单元220向一个或多个辅发送设备中的每个辅发送设备发送的与区域相关联的信息可以是相同的，也可以是不相同的。当辅发送设备收到了与区域相关联的信息之后可以在与主发送设备约定好的特定时间期间生成波束信号并向该区域发送波束信号。
根据本公开的实施例，波束赋形单元230可以在特定时间期间与一个或多个辅发送设备同时生成波束信号并向该区域发送波束信号。也就是说，在特定时间期间，主发送设备与一个或多个辅发送设备都向同一个扫描区域发送波束信号。
由此可见，根据本公开的实施例的电子设备200，可以确定用于特定时间期间的波束赋形的区域，并可以将与该区域相关联的信息发送至辅发送设备，由此主发送设备和辅发送设备可以同时向该扫描区域发送波束信号。这样一来，可以实现不同的发送设备同时对一个扫描区域发送波束信号，以实现波束间的同步。
图3是示出根据本公开的实施例的扫描区域的示意图。如图3所示，A、B和C表示三个发送设备，其中一个是主发送设备，另外两个是辅发送设备。由于A、B和C中的每一个都可以采用波束赋形，即利用天线阵列来形成波束。因此A、B和C中的每一个都可以包括天线阵列。在图3中，用天线阵列的俯视图来表示每个发送设备。如图3所示，灰色区域表示主发送设备确定的用于波束赋形的区域，字母O表示区域的中心，该区域位于由连接A、B和C中的每两个相邻的发送设备的连线组成的三角形的内部。
值得注意的是，图3虽然示出了用于波束赋形的区域是圆形的情形，但是区域也可以是其它形状的二维平面区域。此外，区域还可以为三维空间区域。例如，当无线通信系统中包括具有高度信息的用户设备(例如无人机)时，区域可以为三维空间区域。此外，区域的尺寸是由主发送设备根据波束的宽度、区域的位置和发送设备的灵敏度等参数确定的。
图4是示出根据本公开的实施例的主发送设备和辅发送设备同时向用于波束赋形的区域发送波束信号的示意图。如图4所示，A、B和C中的每个发送设备同时生成波束信号，并向用于波束赋形的区域发送波束信号。
根据本公开的实施例，在特定时间期间开始的时候，主发送设备和辅发送设备都开始向同一个扫描区域发送波束信号。进一步，特定时间期间可以包括一个或多个OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)符号，在特定时间期间的每个OFDM符号中，主发送设备和辅发送设备都向同一个扫描区域发送波束信号。因此，在本公开的实施例中，特定时间期间可以表示扫描参数保持不变的时间。也就是说，在特定时间期间，主发送设备和辅发送设备关于波束赋形的参数保持不变，从而能够保证在整个特定时间期间都向同一个扫描区域发送波束信号。因此，在本公开的实施例中，主发送设备和辅发送设备可以同步地进行波束赋形，即“同时”向一个扫描区域发送波束信号。
根据本公开的实施例，主发送设备和辅发送设备进行波束赋形的行 为可以是周期性的。也就是说，在一个波束赋形周期中，主发送设备和辅发送设备进行波束赋形的参数不变，在不同的波束赋形周期中进行波束赋形的参数不同。根据本公开的实施例，特定时间期间可以为下一个波束赋形周期。这里约定主发送设备和辅发送设备的波束赋形周期相同并且同步。因此，当主发送设备向辅发送设备发送了与区域相关联的信息后，辅发送设备可以在当前时刻的下一个波束赋形周期向该区域发送波束信号，而主发送设备也可以在当前时刻的下一个波束赋形周期向该区域发送波束信号，以达到同时的目的。
根据本公开的实施例，主发送设备和辅发送设备的波束赋形周期可以是时隙级的，即波束赋形周期为一个或多个时隙；也可以是符号级的，即波束赋形周期为一个或多个OFDM符号。
根据本公开的实施例，主发送设备/辅发送设备发送的波束信号可以包括数据信息或例如参考信号的控制信息，即，主发送设备/辅发送设备形成波束指向该区域并通过功率控制向该区域发送波束信号。
如图2所示，电子设备200还可以包括计算单元240，被配置为计算与区域相关联的信息。根据本公开的实施例，与所述区域相关联的信息可以包括与区域的位置相关联的信息。也就是说，辅发送设备可以通过该信息直接获知区域的位置，或者可以通过该信息向区域所在的位置发送波束信号。
根据本公开的实施例，与区域相关联的信息包括区域的位置信息，位置信息用于一个或多个辅发送设备确定波束的方向信息和功率信息。这里，与区域相关联的信息可以包括区域的位置信息，以使得每个辅发送设备根据区域的位置信息来确定该辅发送设备波束的方向信息和功率信息。在这种情况下，主发送设备向每个辅发送设备发送的与区域相关联的信息是相同的，然后每个辅发送设备根据该信息确定波束的方向信息和功率信息。
根据本公开的实施例，与区域相关联的信息包括针对一个或多个辅发送设备中的每个辅发送设备的波束的方向信息和功率信息。在这种情况下，主发送设备向每个辅发送设备发送的与区域相关联的信息是不同的。也就是说，主发送设备可以分别向每个辅发送设备发送针对该辅发送设备的波束的方向信息和功率信息。
根据本公开的实施例，波束的方向信息可以确定波束的方向，而波 束的功率信息可以确定波束在上述方向上传输的距离。也就是说，由波束的方向信息和功率信息两者可以确定波束所能够到达的最远区域。
根据本公开的实施例，计算单元240不仅可以计算针对每个辅发送设备的波束的方向信息和功率信息，还可以计算针对电子设备200的波束的方向信息和功率信息。下面将详述计算单元240的计算过程。
根据本公开的实施例，计算单元240可以根据每个辅发送设备的位置信息和区域的位置信息确定针对每个辅发送设备的波束的功率信息。进一步，计算单元240可以根据电子设备200的位置信息和区域的位置信息确定针对电子设备200的波束的功率信息。
根据本公开的实施例，计算单元240可以根据发送设备与区域之间的距离确定针对该发送设备的波束的功率信息。即，计算单元240可以根据辅发送设备与区域之间的距离确定针对该辅发送设备的波束的功率信息，并根据电子设备200与区域之间的距离确定针对电子设备200的波束的功率信息。这里，在计算与区域之间的距离时，可以用区域的中心来代表区域从而计算与区域的中心之间的距离。根据本公开的实施例，计算单元240在获取了发送设备与区域之间的距离之后，可以根据本领域中公知的任意一种方法(例如，链路预算的方法)来确定针对该发送设备的波束的功率信息，本公开对此不做限定。
图5是示出根据本公开的实施例的确定波束的功率信息的示意图。如图5所示，假定A是作为主发送设备的电子设备200，B和C是辅发送设备，则A可以根据O和A两点之间的距离OA确定针对电子设备200的波束的功率信息，根据O和B两点之间的距离OB确定针对辅发送设备B的波束的功率信息，根据O和C两点之间的距离OC确定针对辅发送设备C的波束的功率信息。
根据本公开的实施例，计算单元240可以根据电子设备200与区域之间的距离以及辅发送设备的位置信息来确定辅发送设备与区域之间的距离。这里，由于区域是电子设备200确定的，因此电子设备200可以计算出电子设备200与区域之间的距离。进一步，计算单元240还需要获取每个辅发送设备的位置，从而可以计算出电子设备200与每个辅发送设备之间的距离以及连接电子设备200与辅发送设备的连线与连接电子设备200与区域的连线之间的夹角。根据本公开的实施例，电子设备200的计算单元240可以通过各种方法获取每个辅发送设备的位置，例如通过辅发送设备上报的方式，或者通过由基站设备通知的方式等等，本公开对此不 做限定。仍然以图5为例，计算单元240获取了OA后，可以根据下式来计算OB和OC：
Figure PCTCN2018116903-appb-000001
Figure PCTCN2018116903-appb-000002
这里，OA可以由主发送设备A直接获取，而当主发送设备A获取了B和C的位置信息后，可以获取AB和AC的值，以及∠OAB和∠OAC的角度值。
根据本公开的实施例，计算单元240可以根据电子设备200、一个或多个辅发送设备和区域的位置信息以及发送设备的天线阵列的方向信息确定针对该发送设备的波束的方向信息。也就是说，计算单元240可以根据电子设备200、每个辅发送设备和区域的位置信息以及辅发送设备的天线阵列的方向信息确定针对辅发送设备的波束的方向信息。进一步，计算单元240还可以根据电子设备200、每个辅发送设备和区域的位置信息以及电子设备200的天线阵列的方向信息确定针对电子设备200的波束的方向信息。
根据本公开的实施例，计算单元240可以确定连接发送设备和区域的连线的方向与发送设备的天线阵列的宽侧(Broadside)方向之间的夹角，该夹角也称为发送设备的发射角(AoD，Angle of Departure)，并根据该夹角来确定针对发送设备的波束的方向信息。这里，每个发送设备获取了发射角后，就可以确定针对发送设备的波束的方向信息。
图6是示出根据本公开的实施例的确定波束的方向信息的示意图。如图6所示，每个发送设备的天线阵列附近的虚线示出了天线阵列的宽侧方向。这里，天线阵列的宽侧方向指的是与天线阵列的两个轴线均垂直的方向，而轴线表明了天线阵列的排列方向。如图6所示，主发送设备A的宽侧方向与OA之间的夹角为主发送设备A的发射角，辅发送设备B的宽侧方向与OB之间的夹角为辅发送设备B的发射角，辅发送设备C的宽侧方向与OC之间的夹角为辅发送设备C的发射角。根据本公开的实施例，计算单元240可以确定每个发送设备的发射角。
根据本公开的实施例，计算单元240可以根据所有发送设备的位置信息和区域的位置信息计算出每个发送设备的波束扫描角，并且根据每个发送设备的波束扫描角和该发送设备的天线阵列的方向来确定该发送设备的发射角。这里，定义发送设备的波束扫描角为如下两个方向的夹角： 连接该发送设备与区域的连线的方向；以及连接该发送设备与相邻的一个发送设备的连线的方向。仍然以图6为例，定义OA的方向和AB的方向之间的夹角∠OAB为主发送设备A的波束扫描角。同理，可以定义∠OBC为辅发送设备B的波束扫描角，定义∠OCA为辅发送设备C的波束扫描角。
根据本公开的实施例，作为主发送设备A的电子设备200的计算单元240在获知了辅发送设备B的位置并确定了区域的位置之后，可以直接确定∠OAB的角度值。进一步，计算单元240可以根据以下公式来确定∠OBC和∠OCA的角度值：
Figure PCTCN2018116903-appb-000003
Figure PCTCN2018116903-appb-000004
这里，arccos表示反余弦函数，并且BC和AC的值在获知了B和C的位置之后即可计算出来，OB、OC和OA的值在计算发送设备的波束的功率信息时已经计算出来。
根据本公开的实施例，通信单元220可以从一个或多个辅发送设备中的每个辅发送设备接收该辅发送设备的天线阵列的方向信息。这里，可以用发送设备的天线阵列的轴线方向与连接该发送设备与相邻的一个发送设备之间的连线的方向之间的夹角来表示天线阵列的方向信息。图7是示出根据本公开的实施例的天线阵列的方向信息的示意图。如图7所示，用主发送设备A的天线阵列的轴线与AB方向的夹角α来表示主发送设备A的天线阵列的方向信息。同理地，可以用辅发送设备B的天线阵列的轴线与BC方向的夹角β来表示辅发送设备B的天线阵列的方向信息，用辅发送设备C的天线阵列的轴线与AC方向的夹角γ来表示辅发送设备C的天线阵列的方向信息。这里，每个辅发送设备都可以向主发送设备上报该辅发送设备的天线阵列的方向信息。
根据本公开的实施例，计算单元240在获取了发送设备的天线阵列的方向信息和发送设备的波束扫描角之后，可以根据上述信息来确定该发送设备的发射角。
图8是示出根据本公开的实施例的天线阵列的立体示意图。如图8 所示，天线阵列设置在天线阵列板上，该天线阵列有两条互相垂直的轴线，与这两条轴线都垂直的方向定义为宽侧方向。进一步，轴线与AB的夹角α表示发送设备A的天线阵列的方向信息，OA和AB之间的夹角∠OAB定义为发送设备A的波束扫描角。而宽侧方向与OA之间的夹角定义为发送设备A的发射角。如图8所示，可以根据下述公式来计算发送设备A的发射角：
A的发射角＝π/2-∠OAB-α。
类似地，计算单元240还可以计算发送设备B和C的发射角为：
B的发射角＝∠OBC-π/2+β
C的发射角＝π/2-∠OCA-γ。
根据本公开的实施例，当用于波束赋形的区域为三维空间区域时，计算单元240在计算方向信息时还可以计算AO、BO和CO与水平方向的夹角，以使得主发送设备和辅发送设备发送的波束可以到达三维的区域。此外，计算单元240也可以不计算上述夹角，波束赋形单元230在进行波束赋形时可以先扫描位于地面上的二维的区域，再扫描该区域的空间区域。
如上所述，计算单元240可以根据发送设备与区域之间的距离确定针对每个发送设备的波束的功率信息，并进一步可以确定针对每个发送设备的波束的方向信息，例如用每个发送设备的发射角来表示波束的方向信息。值得注意的是，如上以两个辅发送设备(即相邻的发送设备之间的连线可以构成一个三角形)为例对方向信息和功率信息的计算进行了描述，但是对于其它数目的辅发送设备的情形可以采用类似的方法对方向信息和功率信息进行计算。因此，通信单元220可以将针对每个发送设备的波束的功率信息和方向信息发送至相应的发送设备。进一步，计算单元240还可以将针对电子设备200的波束的方向信息和功率信息发送至波束赋形单元230。
根据本公开的实施例，波束赋形单元230可以根据计算单元240计算出的针对电子设备200的波束的方向信息和功率信息在特定时间期间向用于波束赋形的区域发送波束信号。也就是说，波束赋形单元230根据波束的方向信息确定发送波束的方向，并根据波束的功率信息确定发送波束的功率。进一步，波束赋形单元230需要在与辅发送设备约定好的特定时间期间根据上述参数发送波束信号。
根据本公开的实施例，计算单元240可以将与区域相关联的位置信息发送至辅发送设备。与区域相关联的位置信息可以包括区域的位置信息，从而使得辅发送设备可以计算波束的方向信息和功率信息。与区域相关联的位置信息也可以包括针对辅发送设备的波束的方向信息和功率信息。也就是说，计算针对辅发送设备的波束的方向信息和功率信息的主体可以为主发送设备，也可以为辅发送设备。当主发送设备和辅发送设备获取了波束的方向信息和功率信息以后，可以在特定时间期间根据各自的参数向同一个区域发送波束信号，由此实现不同的发送设备同时向一个区域发送波束信号。
根据本公开的实施例，主发送设备和辅发送设备是针对用户设备而言的。也就是说，不同的用户设备的主发送设备和辅发送设备可以是不同的。进一步，可以用多种方法来选择无线通信系统中的主发送设备和辅发送设备。例如，由当前为用户设备提供服务的发送设备来确定该用户设备的主发送设备和辅发送设备。例如，为用户设备提供服务的发送设备可以确定自己为主发送设备，确定与该发送设备相邻的一个或多个发送设备为辅发送设备，具体的选取原则可以根据实际情况而定，本公开对比不做限定。当然，也可以由用户设备周围的所有发送设备通过交互信息来确定主发送设备和辅发送设备。
也就是说，根据本公开的实施例，如图2所示，电子设备200还可以包括确定单元250，用于确定电子设备200作为主发送设备，并且可以从无线通信系统中的多个发送设备中选取一个或多个发送设备作为辅发送设备。进一步，通信单元220可以向一个或多个辅发送设备发送指示信息，以指示一个或多个辅发送设备用作辅发送设备。
根据本公开的实施例，指示信息还可以包括主发送设备和其它辅发送设备的识别信息，以用于接收指示信息的辅发送设备获取该用户设备的所有发送设备的信息。进一步，指示信息还可以包括主发送设备和其它辅发送设备的位置信息和/或天线阵列的方向信息等参数，以用于辅发送设备计算针对该辅发送设备的波束的方向信息和功率信息。
根据本公开的实施例，响应于电子设备200发送的指示信息，辅发送设备可以向电子设备200发送辅发送设备的位置信息和/或天线阵列的方向信息等参数，以用于电子设备200计算针对该辅发送设备的波束的方向信息和功率信息。
根据本公开的实施例，电子设备200还可以向用户设备发送电子设 备200和一个或多个辅发送设备的识别信息，以用于用户设备知晓其所有的发送设备的信息，例如可以用于对来自电子设备200和一个或多个辅发送设备的信息进行检测等目的。
图9是示出根据本公开的实施例的确定主发送设备和辅发送设备的的信令流程图。如图9所示，在步骤S901中，为用户设备提供服务的发送设备确定自己为主发送设备，并确定辅发送设备，这里假定主发送设备确定了两个辅发送设备：辅发送设备1和辅发送设备2。接下来，在步骤S902中，主发送设备向辅发送设备1和辅发送设备2分别发送指示信息，以指示其用作辅发送设备。接下来，在步骤S903中，辅发送设备1和辅发送设备2分别向主发送设备上报参数，这里的参数例如可以包括位置信息和/天线阵列的方向信息等。接下来，可选地，在步骤S904中，主发送设备可以向用户设备发送主发送设备和辅发送设备的识别信息。
如上所述，可以由用户设备周围的发送设备(例如当前为该用户设备提供服务的发送设备)来确定该用户设备的主发送设备和辅发送设备。下面将详细描述另一种确定主发送设备和辅发送设备的方式。
根据本公开的实施例，主发送设备和辅发送设备也可以由无线通信系统中的基站设备来确定。这里的基站设备可以是当前为用户设备提供服务的基站设备，例如当前为用户设备提供服务的发送设备所在的小区的基站设备。
根据本公开的实施例，电子设备200的通信单元220可以从无线通信系统中的基站设备接收指示信息，指示信息用于指示电子设备200用作主发送设备。进一步，指示信息还可以包括一个或多个辅发送设备的识别信息，以用于电子设备200知晓所有辅发送设备，便于后续的计算。
根据本公开的实施例，电子设备200还可以包括估计单元260，用于估计电子设备200与用户设备之间的链路质量。根据本公开的实施例，估计单元260可以响应于来自用户设备的参考信号信息来估计电子设备200与用户设备之间的链路质量。这里，用户设备可以向其周围的多个发送设备发送参考信号，以使得多个发送设备均估计其与用户设备之间的链路质量。
根据本公开的实施例，通信单元220还可以将链路质量信息发送至基站设备，以用于基站设备根据链路质量信息确定主发送设备和一个或多个辅发送设备。这里，用户设备周围的所有发送设备都可以发送链路质量 信息至基站设备，以用于基站设备选取主发送设备和辅发送设备。例如，基站设备可以选择链路质量最好的发送设备作为主发送设备，选择链路质量较好的其它发送设备作为辅发送设备，具体的选择规则本公开不做限定。
图10(a)是示出根据本公开的另一个实施例的确定主发送设备和辅发送设备的信令流程图。如图10(a)所示，在步骤S1001中，用户设备向其周围的所有发送设备发送参考信号，这里假定用户设备向三个发送设备发送了参考信号。接下来，在步骤S1002中，三个发送设备响应于接收到的参考信号对发送设备与用户设备之间的链路质量进行测量。接下来，在步骤S1003中，三个发送设备分别向基站设备发送链路质量测量的测量报告。接下来，在步骤S1004中，基站设备根据接收到的测量报告选择合适的主发送设备和辅发送设备。接下来，在步骤S1005中，基站设备向主发送设备和辅发送设备发送指示信息，以指示哪个发送设备用作主发送设备和哪些发送设备用作辅发送设备。接下来，与图9中的步骤S903类似，在步骤S1006中，辅发送设备可以向主发送设备上报相关的参数。接下里，可选地，与图9中的步骤S904类似，在步骤S1007中，主发送设备可以向用户设备发送主发送设备和辅发送设备的识别信息。如图10(a)所示，基站设备可以根据发送设备测量的用户设备与发送设备之间的上行链路的质量来确定主发送设备和辅发送设备。
图10(b)是示出根据本公开的又一个实施例的确定主发送设备和辅发送设备的信令流程图。如图10(b)所示，在步骤S1001中，用户设备周围的所有发送设备向用户设备发送参考信号，这里假定三个发送设备向用户设备发送了参考信号。根据本公开的实施例，由于用户设备周围的发送设备可能不知晓用户设备的位置所以无法向用户设备发送波束信号。在这种情况下，发送设备可以利用诸如广播信道的公共控制信道向用户设备发送参考信号。接下来，在步骤S1002中，用户设备响应于接收到的多个参考信号分别测量用户设备与多个发送设备之间的下行链路质量。接下来，在步骤S1003中，用户设备向基站设备发送链路质量测量的测量报告，测量报告可以包括针对不同的发送设备的链路质量的测量结果。接下来，在步骤S1004中，基站设备根据接收到的测量报告选择合适的主发送设备和辅发送设备。接下来，在步骤S1005中，基站设备向主发送设备和辅发送设备发送指示信息，以指示哪个发送设备用作主发送设备和哪些发送设备用作辅发送设备。接下来，与图9中的步骤S903类似，在步骤S1006中，辅发送设备可以向主发送设备上报相关的参数。接下里，可选地，与 图9中的步骤S904类似，在步骤S1007中，主发送设备可以向用户设备发送主发送设备和辅发送设备的识别信息。如图10(b)所示，基站设备可以根据发送设备测量的用户设备与发送设备之间的下行链路的质量来确定主发送设备和辅发送设备。
如上所述，可以由基站设备来为用户设备确定主发送设备和辅发送设备。这样一来，选择的主发送设备和辅发送设备的链路质量都比较好，使得用户设备接收到的信号质量也比较好，有助于后续的波束赋形过程。
根据本公开的实施例的电子设备200可以协助参与各种通信过程，力图对用户设备进行定位、用户设备的切换以及CoMP传输等，下面将详细描述为了实现这几种通信过程的电子设备200的配置。
<2.2用于对用户设备进行定位的配置>
根据本公开的实施例，由于主发送设备和辅发送设备可以同时向一个区域发送波束信号，因而可以实现对用户设备的定位。
根据本公开的实施例，定位的过程可以是由用户设备触发的，也可以是由为用户设备提供服务的基站设备触发的。此外，为了实现定位，需要有多个辅发送设备，也就是说，至少需要三个发送设备同时向一个区域发送波束信号。
根据本公开的实施例，由于电子设备200和辅发送设备并不知晓用户设备的位置，因此电子设备200的确定单元210可以根据用户设备在各个位置出现的概率来确定用于波束赋形的区域，并优先选择用户设备出现的概率较高的位置作为用于波束赋形的区域。也就是说，用于波束赋形的区域是用户设备可能出现的位置。例如，电子设备200可以根据用户设备的历史信息(例如，用户经常出现的地方、用户初始接入该无线通信系统时的位置等信息)估计用户设备在各个位置出现的概率，并选择用户设备出现概率最高并且尚未被扫描过的区域作为用于波束赋形的区域。这里，在用于对用户设备进行定位的配置中，由于主发送设备和辅发送设备并不知晓用户设备的位置，因此只能逐一向各个区域发送波束信号直到确定用户设备的位置为止，因此这样的过程也可以称为“波束扫描”的过程。也就是说，确定的用于波束赋形的区域可以称为扫描区域，并且波束赋形的周期也可以称为扫描周期。
根据本公开的实施例，电子设备200的通信单元220可以向用户设 备发送电子设备200和一个或多个辅发送设备的识别信息，以用于用户设备对来自电子设备200和一个或多个辅发送设备的信息进行检测。也就是说，无论主发送设备和辅发送设备是由哪个实体确定的，作为主发送设备的电子设备200都可以向用户设备发送所有发送设备的识别信息。这样一来，用户设备可以确定需要检测哪些发送设备的信号以实现定位。
根据本公开的实施例，通信单元220可以从用户设备接收对电子设备200和一个或多个辅发送设备发送的波束信号的反馈信息，该反馈信息可以表明用户设备是否接收到了来自全部发送设备的波束信号。
根据本公开的实施例，用户设备可以只有在接收到了来自全部发送设备的波束信号的情况下才向主发送设备发送反馈信息。也就是说，反馈信息表明用户设备接收到了来自电子设备200和所有辅发送设备的波束信号。这样一来，电子设备200可以设置定时器，在定时器期满前没有收到反馈信息的情况下了可以确定用户设备没有位于本次扫描的区域中；如果电子设备200在定时器期满前收到了反馈信息，则可以确定用户设备位于本次扫描的区域中。在这种情况下，反馈信息可以包括定位需要的各种参数，例如，当采用TDOA(Time Difference of Arrival，到达时间差)算法时，反馈信息可以包括来自各个发送设备的波束信号的到达时间等信息。本公开可以采用本领域中公知的任意一种算法对用户设备进行定位，因此对定位算法以及反馈信息不做限定。
根据本公开的实施例，用户设备也可以在每个波束扫描周期都向电子设备200发送反馈信息，该反馈信息需要表明用户设备是否在上一个波束扫描周期接收到了来自全部发送设备的波束信号。例如，用户设备在第n个扫描周期没有收到来自全部发送设备的波束信号，则在第n+1个扫描周期向电子设备200发送反馈信息，以表明用户设备在n个扫描周期没有收到来自全部发送设备的波束信号；用户设备在第n+1个扫描周期接收到了来自全部发送设备的波束信号，则在第n+2个扫描周期向电子设备200发送反馈信息，反馈信息中可以包括定位需要的各种参数。这样一来，电子设备200可以确定在第n+1个扫描周期中扫描的区域是用户所在的位置，从而实现定位。
根据本公开的实施例，当电子设备200接收到了包括定位需要的各种参数的反馈信息后，可以由电子设备200来计算用户设备的位置，也可以将上述信息发送至为用户设备提供服务的基站设备，由基站设备来计算用户设备的位置。
根据本公开的实施例，如图2所示，电子设备200还可以包括定位单元270，用于根据来自用户设备的反馈信息对用户设备进行定位。本公开对定位算法不做限定。
根据本公开的实施例，当接收到的来自用户设备的反馈信息表明用户设备没有接收到来自全部发送设备的波束信号，或者在定时器期满没有收到来自用户设备的反馈信息的情况下，确定单元210还可以重新确定用于特定时间期间的波束赋形的区域，通信单元220还可以将与重新确定的区域相关联的信息发送至一个或多个辅发送设备，并且波束赋形单元230还可以在特定时间期间向重新确定的区域发送波束信号。这里，确定单元210仍然可以选择用户设备出现概率最高并且尚未被扫描过的区域作为用于波束赋形的区域，也就是说，确定单元210可以从尚未被扫描过的区域中选择用户设备出现概率最高的区域作为用于波束赋形的区域。后续的处理流程与前述描述的过程类似，在此不再赘述。根据本公开的实施例，电子设备200可以重复执行这样的过程，直到接收到来自用户设备的表明用户设备接收到来自全部发送设备的波束信号的反馈信息从而实现定位为止。
图11(a)是示出根据本公开的实施例的对用户设备进行定位的信令流程图。图11(a)示出了无线通信系统包括一个主发送设备和两个辅发送设备的情形。在图11(a)中，用户设备可以只有在接收到了来自全部发送设备的波束信号的情况下才向主发送设备发送反馈信息。如图11(a)所示，在步骤S1101中，主发送设备确定用于波束赋形的区域。接下来，在步骤S1102中，主发送设备将与该区域相关联的信息发送至辅发送设备1和辅发送设备2。接下来，在步骤S1103中，主发送设备和辅发送设备同时向该区域发送波束信号。接下来，在步骤S1104中，主发送设备设置定时器并确定在定时器期满前是否收到了来自用户设备的反馈信息，这里假定主发送设备在定时器期满前没有收到来自用户设备的反馈信息。接下来，在步骤S1105中，主发送设备重新确定用于波束赋形的区域。接下来，在步骤S1106中，主发送设备将与重新确定的区域相关联的信息发送至辅发送设备1和辅发送设备2。接下来，在步骤S1107中，主发送设备和辅发送设备同时向重新确定的区域发送波束信号。接下来，在步骤S1108中，假定用户设备在定时器期满前向主发送设备发送了反馈信息。接下来，在步骤S1109中，主发送设备设置定时器并确定在定时器期满前收到了来自用户设备的反馈信息。接下来，在步骤S1110中，主发送设备可以根据收到的反馈信息进行定位计算。
图11(b)是示出根据本公开的另一个实施例的对用户设备进行定位的信令流程图。图11(b)示出了无线通信系统包括一个主发送设备和两个辅发送设备的情形。在图11(b)中，用户设备在每个波束赋形周期都向主发送设备发送反馈信息，该反馈信息需要表明用户设备是否在上一个波束赋形周期接收到了来自全部发送设备的波束信号。如图11(b)所示，在步骤S1101中，主发送设备确定用于波束赋形的区域。接下来，在步骤S1102中，主发送设备将与该区域相关联的信息发送至辅发送设备1和辅发送设备2。接下来，在步骤S1103中，主发送设备和辅发送设备同时向该区域发送波束信号。接下来，在步骤S1104中，用户设备向主发送设备发送反馈信息，该反馈信息表明用户设备在上一个波束赋形周期没有收到来自全部发送设备的波束信号。接下来，在步骤S1105中，主发送设备根据反馈信息确定用户设备没有收到来自全部发送设备的波束信号。接下来，在步骤S1106中，主发送设备重新确定用于波束赋形的区域。接下来，在步骤S1107中，主发送设备将与重新确定的区域相关联的信息发送至辅发送设备1和辅发送设备2。接下来，在步骤S1108中，主发送设备和辅发送设备同时向重新确定的区域发送波束信号。接下来，在步骤S1109中，用户设备向主发送设备发送反馈信息，该反馈信息表明用户设备在上一个波束赋形周期收到了来自全部发送设备的波束信号。接下来，在步骤S1110中，主发送设备确定用户设备收到了来自全部发送设备的波束信号。接下来，在步骤S1111中，主发送设备可以根据收到的反馈信息进行定位计算。
图12(a)是示出根据本公开的实施例的对用户设备进行定位的示意图。如图12(a)所示，主发送设备可以根据用户设备的历史信息对多个区域进行优先级排序，并按照优先级从高到低的顺序依次将多个区域设置为用于波束赋形的区域。这里优先级的设置可以例如根据用户设备出现的概率高低，用户设备出现的概率越高，该区域的优先级越高等。这里假定四个区域O1、O2、O3和O4的优先级依次降低，并且需要定位的用户设备位于O2中。
图12(b)是示出针对图12(a)所示的情形的根据本公开的实施例的对用户设备进行定位的时序图。在图12(b)中，采用用户设备在每个波束赋形周期都上报反馈信息的方式。如图12(b)所示，在第n个周期中，主发送设备确定O1作为用于波束赋形的区域，并计算区域O1的相关参数(例如区域O1的位置信息、针对主发送设备和辅发送设备的波束的方向信息和功率信息等)。进一步，在第n个周期中主发送设备将与O1 相关联的信息发送至辅发送设备。接下来，在第n+1个扫描周期中，主发送设备和辅发送设备可以同时生成波束从而向O1发送波束信号。同时，在第n+1个周期中，主发送设备还需要将区域O2作为用于波束赋形的区域，并计算与O2相关联的参数以及发送至辅发送设备。接下来，在第n+2个周期，主发送设备和辅发送设备可以同时生成波束从而向O2发送波束信号。同时，在第n+2个周期中，用户设备可以向主发送设备发送反馈信息，以表明用户设备是否在第n+1个周期接收到了来自所有发送设备的波束信号，这里假定用户设备的反馈信息表明没有在第n+1个周期接收到了来自所有发送设备的波束信号。也就是说，用户设备没有位于O1中。在第n+2个周期中，主发送设备还需要将区域O3作为用于波束赋形的区域，并计算与O3相关联的参数以及发送至辅发送设备。接下来，在第n+3个周期，主发送设备和辅发送设备可以同时生成波束从而向O3发送波束信号。同时，在第n+3个周期中，用户设备可以向主发送设备发送反馈信息，以表明用户设备是否在第n+2个周期接收到了来自所有发送设备的波束信号，这里假定用户设备的反馈信息表明在第n+2个周期接收到了来自所有发送设备的波束信号。也就是说，用户设备位于O2中。此时，主发送设备正在将区域O4作为用于波束赋形的区域，并计算与O4相关联的参数以及发送至辅发送设备，由于主发送设备接收反馈信息需要一定的时间，因而可能已经计算了一部分与O4相关联的参数。当主发送设备接收到表明用户设备在第n+2个周期接收到了来自所有发送设备的波束信号的反馈信息后，立即停止计算参数，并根据反馈的参数对用户设备进行定位。
如上所述，根据本公开的实施例的电子设备200可以依次将不同的区域确定为用于波束赋形的区域，并与辅发送设备同时扫描每个区域，直到确定出用户设备的位置为止。这里，由于用户设备可能是移动的，因此多个发送设备同时发送波束能够实现更精确的定位效果。
<2.3用于用户设备的切换的配置>
当用户设备从一个发送设备(例如TRP或基站等)的覆盖范围移动到另一个发送设备的覆盖范围时就需要进行切换。在切换的过程中，为了保持连接的稳定，通常采用“软切换”(Soft handover)的方式，即先与多个发送设备进行连接然后断开与原先提供服务的发送设备的连接。为了实现“软切换”，用户需同时接收多个发送设备发来的信号。在切换的过 程中，用户设备需建立有效集、相邻集和候选集三个集合，并保持与这些集合中的发送设备的连接。其中，有效集是指正在与用户设备“软切换”相连接的发送设备形成的集合；候选集指当前的发送设备不在有效集里，没有参与软切换，但是已有足够的导频强度表明该发送设备可以被加到有效集里；相邻集(监测集)是指当前不在候选集里，但根据某种算法被认为很快可以进入候选集的发送设备的集合。移动台对于列在相邻集里的小区要连续搜索和测量，但是在测量的时间里，导频强度还没有强到可以增加到候选集中。
而在采用波束赋形的无线通信系统中，信号均通过模拟/数字预编码形成波束来进行发送。在这种情况下，要实现“软切换”，需要多个发送设备发出的波束同步照射到用户设备，因此根据本公开的实施例的电子设备200可以用于这种过程。
在用于切换的实施例中，由于用户设备的位置是已知的，所以确定单元210可以根据用户设备的位置信息确定用于特定时间期间的波束赋形的区域。也就是说，用户设备位于确定的区域中。
根据本公开的实施例，电子设备200或者为用户设备提供服务的基站设备还可以确定有效集中接收信号功率最强(或者信噪比最大)的发送设备作为主发送设备，有效集中的其它发送设备以及候选集和相邻集中的发送设备作为辅发送设备。
根据本公开的实施例，当电子设备200属于有效集时，其利用波束向该区域发送控制信号和数据信号；当电子设备200属于候选集或相邻集时，其利用波束向该区域发送控制信号。同理，当辅发送设备属于有效集时，其利用波束向该区域发送控制信号和数据信号；当辅发送设备属于候选集或相邻集时，其利用波束向该区域发送控制信号。
根据本公开的实施例，用户设备可以根据接收到的来自所有发送设备的波束信号来确定有效集、候选集和相邻集中的发送设备。例如，如果候选集中的发送设备利用波束发送的控制信号足够强，且有效集未满，将该发送设备移入有效集；如果相邻集中的发送设备利用波束发送的控制信号足够强，且候选集未满，将该发送设备移入候选集；如果有效集中的发送设备利用波束发送的控制信号的强度变弱，且候选集未满，将该发送设备移入候选集；如果候选集中的发送设备利用波束发送的控制信号的强度变弱，且相邻集未满，将该发送设备移入相邻集。
根据本公开的实施例，电子设备200可以追踪用户设备的位置，并且当电子设备200确定用户设备发生移动时，可以根据移动后的位置重新执行上述过程。即，确定单元210可以根据移动后的用户设备的位置信息重新确定用于特定时间期间的波束赋形的区域，通信单元220可以将与重新确定的区域相关联的信息发送至一个或多个辅发送设备，以用于一个或多个辅发送设备在特定时间期间向重新确定的区域发送波束信号，并且波束赋形单元230可以在特定时间期间向重新确定的区域发送波束信号。同样地，确定单元210重新确定的区域也是根据用户设备的移动后的位置确定的，后续的流程与前文中所述类似，在此不再赘述。
如上所述，根据本公开的实施例的电子设备200，可以根据用户的位置确定用于波束赋形的区域，从而使得电子设备200和辅发送设备同时向一个区域发送波束信号，以便于用户设备更加精确地确定与切换有关的集合，实现软切换。
<2.4用于CoMP的配置>
CoMP指多个发送设备通过相互协作同时为一个用户设备提供服务。这些发送设备在地理上分离，通过相关的接口或光纤而无线相连。CoMP利用宏分集技术提高了小区边缘的频谱效率，扩大了小区的覆盖范围。下行CoMP按照数据处理方式不同可分为多点联合处理和多点协调调度。在多点联合处理方式中，多个发送设备需要同时向用户设备发送数据。
而在采用波束赋形的无线通信系统中，信号均通过模拟/数字预编码形成波束来进行发送。在这种情况下，要实现多点联合处理，需要多个发送设备发出的波束同步照射到用户设备，因此根据本公开的实施例的电子设备200可以用于这种过程。
在用于CoMP传输的实施例中，由于用户设备的位置是已知的，所以确定单元210可以根据用户设备的位置信息确定用于特定时间期间的波束赋形的扫描区域。也就是说，用户设备位于确定的区域中。
根据本公开的实施例，电子设备200和辅发送设备可以利用波束向该区域发送数据信号。
根据本公开的实施例，电子设备200可以追踪用户设备的位置，并且当电子设备200确定用户设备发生移动时，可以根据移动后的位置重新 执行上述过程。即，确定单元210可以根据移动后的用户设备的位置信息重新确定用于特定时间期间的波束赋形的区域，通信单元220可以将与重新确定的区域相关联的信息发送至一个或多个辅发送设备，以用于一个或多个辅发送设备在特定时间期间向重新确定的区域发送波束信号，并且波束赋形单元230可以在特定时间期间向重新确定的区域发送波束信号。同样地，确定单元210重新确定的区域也是根据用户设备的移动后的位置确定的，后续的流程与前文中所述类似，在此不再赘述。
由此可见，根据本公开的实施例的电子设备200，可以根据用户的位置确定用于波束赋形的区域，从而使得电子设备200和辅发送设备同时向一个区域发送波束信号，以使得多个发送设备可以通过相互协作同时为一个用户设备提供服务。
由此可见，根据本公开的实施例，主发送设备可以确定用于波束赋形的区域并将与该区域相关联的信息发送至辅发送设备，从而使得主发送设备和辅发送设备同时向该区域发送波束信号，以实现波束间的同步。进一步，这样的过程有助于诸如定位、切换和CoMP的通信过程。

<5.2对用户设备进行定位的方法流程图>
图16是示出根据本公开的实施例的对用户设备进行定位的方法流程图。
如图16所示，在步骤S1510中，无线通信系统中的主发送设备确定用于特定时间期间的波束赋形的区域。接下来，在步骤S1520中，主发送设备将与该区域相关联的信息发送至一个或多个辅发送设备。这里，可以采用前文中所述的任意一种方法来确定无线通信系统中的主发送设备以及一个或多个辅发送设备，并且与该区域相关联的信息也可以是前文中所述的任意一种信息。接下来，在步骤S1530中，主发送设备和辅发送设备在特定时间期间同时向该区域发送波束信号。根据本公开的实施例，主发送设备可以设置定时器，并在步骤S1540中判断在定时器期满前是否收到来自用户设备的反馈信息。这里，如果用户设备位于该区域中，那么会接收到来自主发送设备和辅发送设备的信息，并根据接收到的信息生成反馈信息发送至主发送设备；如果用户设备没有位于该区域中，那么不会接收到来自主发送设备和辅发送设备的信息，那么主发送设备也就不会收到反馈信息。接下来，如果在步骤S1540中主发送设备在定时器期满前接收到了反馈信息，那么在步骤S1550中，主发送设备可以利用反馈信息对用户设备进行定位。这里，定位的方法可以包括但不限于TDOA算法。接下来，如果在步骤S1540中主发送设备在定时器期满前没有接收到反馈信息，那么返回步骤S1510。此时，主发送设备重新确定用于特定时间期间的波束赋形的扫描区域，重新确定的区域与前一次确定的区域为不重合的区域，并且此时的特定时间期间可以为下一个波束赋形周期。

<5.3用户设备的切换的方法流程图>
图17是示出根据本公开的实施例的用于用户设备的切换的方法流程图。
如图17所示，在步骤S1610中，无线通信系统中的主发送设备确定用于特定时间期间的波束赋形的区域。这里，由于用户设备的地理位置是已知的，所以主发送设备可以根据用户设备的位置信息来确定该区域，即，用户设备位于用于波束赋形的区域中。接下来，在步骤S1620中，主发送设备将与该区域相关联的信息发送至一个或多个辅发送设备。这里，可以采用前文中所述的任意一种方法来确定无线通信系统中的主发送设备以及一个或多个辅发送设备，并且与该区域相关联的信息也可以是前文中所述的任意一种信息。接下来，在步骤S1630中，主发送设备和辅发送设备在特定时间期间同时向该区域发送波束信号。根据本公开的实施例，由于用户设备位于该区域中，所以用户设备可以接收到来自主发送设备和辅发送设备的波束信号。接下来，在步骤S1640中，用户设备可以根据对接收到的波束信号进行测量从而确定切换相关的集合，包括但不限于有效集、候选集和相邻集。接下来，在步骤S1650中，用户设备可以判断主发送设备的信号功率是否是有效集中最强的。如果在步骤S1650中确定主发送设备的信号功率不是有效集中最强的，那么在步骤S1660中，可以将有效集中功率最强的发送设备重新确定为新的主发送设备，并将有效集中其它发送设备以及候选集和相邻集中的发送设备确定为新的辅发送设备。如果在步骤S1650中确定主发送设备的信号功率仍然是有效集中最强的，那么在步骤S1670中，不会改变主发送设备，并且主发送设备追踪用户设备的位置。接下来，在步骤S1680中，主发送设备可以判断用户设备的位置是否发生变化。如果在步骤S1680中确定用户设备的位置发生变化，则主发送设备可以根据用户设备变化后的位置重新确定用于波束赋形的区域并从步骤S1610开始重新执行根据本公开的方法。如果在步骤S1680中确定用户设备的位置没有发生变化，则返回步骤S1670继续追踪用户设备的位置，直到用户设备的位置发送变化为止。
如图17所示，主发送设备可以根据用户设备的位置确定用于波束赋 形的区域，并且主发送设备和辅发送设备可以利用波束同时向用户设备发送波束信号，从而用户设备可以利用这些信号确定与切换相关的集合，协助执行切换过程。这样一来，确定出的与切换相关的集合更加精确，从而使得用户设备的切换更加精确有效。

如图18所示，在步骤S1710中，无线通信系统中的主发送设备确定用于特定时间期间的波束赋形的区域。这里，由于用户设备的地理位置是已知的，所以主发送设备可以根据用户设备的位置信息来确定该区域，即，用户设备位于该区域中。接下来，在步骤S1720中，主发送设备将与该区域相关联的信息发送至一个或多个辅发送设备。这里，可以采用前文中所述的任意一种方法来确定无线通信系统中的主发送设备以及一个或多个辅发送设备，并且与该区域相关联的信息也可以是前文中所述的任意一种信息。接下来，在步骤S1730中，主发送设备和辅发送设备在特定时间期间同时向该区域发送波束信号。根据本公开的实施例，由于用户设备位于该区域中，所以用户设备可以接收到来自主发送设备和辅发送设备的波束信号。接下来，在步骤S1740中，用户设备对来自主发送设备和辅发送设备的波束信号进行解调，从而实现CoMP传输。接下来，在步骤S1750中，主发送设备可以追踪用户设备的位置。接下来，在步骤S1760中，主发送设备可以判断用户设备的位置是否发生变化。如果在步骤S1760中确定用户设备的位置发生变化，则主发送设备可以根据用户设备变化后的位置重新确定用于波束赋形的区域并从步骤S1710开始重新执行根据本公开的方法。如果在步骤S1760中确定用户设备的位置没有发生变化，则返回步骤S1750继续追踪用户设备的位置，直到用户设备的位置发送变化为止。
如图18所示，主发送设备可以根据用户设备的位置确定用于波束赋形的区域，并且主发送设备和辅发送设备可以利用波束同时向用户设备发送波束信号，从而实现利用波束的CoMP传输。这样一来，用户设备接收到的信息是主发送设备和辅发送设备同时发送的，不会因为用户设备的位置的改变而导致信息丢失。
以上详述了根据本公开的实施例的方案应用于定位、切换和CoMP 传输等应用的方法流程，但是本公开并不限于此，本公开可以应用于所有需要利用波束同时发送信息的场景。
