Definitions

  • the present invention relates to a beamforming technology in the field of wireless communications, and in particular, to an acquisition method, a beam transmitting method, a communication node, a system, and a storage medium. Background technique
  • Beamforming is a technique for directional transmission of data. By beamforming directional data transmission, energy is concentrated in a useful direction, increasing the signal-to-noise ratio of the system, thereby increasing the coverage of the system.
  • the pilot information refers to information that is known to both the first communication node and the second communication node transmitted by the first communication node on the designated time-frequency resource.
  • the second communication node estimates channel information between the first communication node and the second communication node according to the received pilot information, calculates channel quality information, and selects the best discovered beam according to the channel quality information, so that the feedback channel quality information is compared. A good one or more beams are given to the first communication node.
  • the second communication node may also report channel quality information to the first communication node so that the first communication node has more information to reference when transmitting data.
  • the beamforming is actually applied, since the location of the first communication node is generally relatively fixed, and the second communication node is relatively randomly distributed around the first communication node, the distance between the different second communication nodes is different from the first communication node. Differently, the path loss experienced by the second communication node at different distances is different, so the degree of influence of the second communication node measurement pilot on noise or interference is different, and the reliability is also different.
  • the prior art generally transmits the same feature beam to each second communication node indiscriminately, for example, the same beam transmission power, beam gain, transmission beam multiplexing mode, and number of beams are the same, which leads to path loss.
  • the small second communication node wastes power resources, and the second communication node with large path loss makes the measurement pilot unreliable due to insufficient power resources.
  • the second communication node is on a horizontal plane The distribution may not be uniform. In some areas, the number of second communication nodes is large, and in some areas, there are fewer second communication nodes. As shown in FIG. 1, the corresponding downtilt angles at the same pitch L are different from the vertical direction, and the lower the downtilt angle corresponding to the distance from the first communication node, the larger the area of the formed loop. In Fig.
  • the vertical direction is divided into five regions, which are A, B, C, D, and E in order, and the length of each region is L, and it is apparent that the downtilt angle of the region A is larger than that of the region B.
  • the radius of the A region is small, the area of the area is rather small.
  • the distribution of the second communication node is relatively uniform, the second communication node of the area A is rather less.
  • the second communication node of the area E is more than the second communication node of the area D, and so on.
  • the prior art also transmits beams of the same feature to the second communication node of all areas indiscriminately, which also results in insufficient power or spatial resources in the dense place of the second communication node, and less second communication node.
  • Areas have endless power or airspace resources.
  • the spatial domain resources here are realized by the directionality of beamforming in the airspace. The narrower the beam, the more accurate the division of the airspace.

Description

获取方法、 波束发送方法、 通信节点、 系统和存储介质 技术领域
本发明涉及无线通信领域的波束赋形技术， 尤其涉及一种获取方法、 波束发送方法、 通信节点、 系统和存储介质。 背景技术
波束赋形是一种定向发送数据的技术， 通过波束赋形的定向数据发送， 使得能量集中在有用的方向， 增加了系统的信噪比， 从而提高了系统的覆 盖范围。
导频信息是指第一通信节点在指定的时频资源上发送的一种第一通信 节点和第二通信节点都知道的信息。 第二通信节点根据接收到的导频信息， 估计第一通信节点到第二通信节点间的信道信息， 计算信道质量信息， 根 据信道质量信息选择那个发现的波束最好 , 从而反馈信道质量信息较好的 一个或者多个波束给第一通信节点。 第二通信节点也可以上报信道质量信 息给第一通信节点， 以便于第一通信节点发送数据时有更多的信息参考。
实际应用波束赋形时， 由于第一通信节点位置一般比较固定， 而第二 通信节点比较随机地分布在第一通信节点的周围， 这导致不同的第二通信 节点离第一通信节点的距离是不一样的， 不同距离的第二通信节点经历的 路径损耗是不一样的， 所以第二通信节点测量导频受到噪声或者干扰的影 响程度是不一样， 可靠性也不一样。 现有技术一般不加区分地对每个第二 通信节点发送相同特征的波束， 比如相同的波束的发送功率、 波束增益、 发送波束的复用方式、 波束个数均相同， 这会导致路径损耗小的第二通信 节点浪费了功率资源， 而路径损耗大的第二通信节点由于得不到足够大的 功率资源而使得测量导频不可靠。 另外一方面， 第二通信节点在水平面上 的分布有可能并不均勾， 有的区域第二通信节点数目较多， 有的区域第二 通信节点较少。 如图 1所示， 从垂直方向来看相同间距 L下对应的下倾角 大小是不一样的， 离第一通信节点越远对应的下倾角越小， 但所形成的环 的面积越大。 在图 1中， 垂直方向分成 5个区域， 依次是 A、 B、 C、 D以 及 E且每个区域的长度是 L, 显然区域 A的下倾角比区域 B的大。 但由于 A 区域半径小， 所以区域面积反而更小， 如果第二通信节点分布较均匀， 那么区域 A的第二通信节点反而更少。 同理， 区域 E的第二通信节点比区 域 D的第二通信节点多等等。 现有技术也是不加区分地对所有区域的第二 通信节点发送相同特征的波束， 这也会导致第二通信节点密集的地方得不 到充分的功率或空域资源， 而第二通信节点少的区域有用不完的功率或空 域资源。 这里的空域资源由波束赋形在空域的定向性来实现， 波束越窄对 空域的划分越精确。

以下结合附图对本发明的优选实施例进行详细说明， 应当理解， 以下 所说明的优选实施例仅用于说明和解释本发明， 并不用于限定本发明。
实施例一：
如图 2所示， 本实施例提供一种波束信息获取方法， 所述方法包括： 步骤 S110: 接收第一通信节点发送的至少一种导频波束； 步骤 S120: 获取每种所述导频波束的配置信息或所接收的任意两种所 述导频波束的配置差异信息；
步骤 S130: 根据所述配置信息或所述配置差异信息， 计算所接收的任 意两种导频波束的发射功率的提升值；
步骤 S140: 计算所接收的所述导频波束的信道质量信息；
步骤 S150: 根据所述发射功率的提升值和所述信道质量信息选定导频 波束；
步骤 S160: 4艮据所述导频波束确定波束信息。
所述第一通信节点通常为固定通信节点， 如宏基站、 微基站、 直放站、 中继设备及拉远设备等接入无线网络的无线接入通信设备， 用以通过与第 二通信节点的交互， 实现第二通信节点的无线接入以及通信。 在本实施例 中为从第二通信节点侧描述的波束信息获取方法。 所述波束信息获取后， 所述方法还包括将所述获取的波束信息返回到第一通信节点， 用以第一通 信节点根据返回的波束信息波束赋形。 所述第二通信节点通常为： 数据卡、 手机、 笔记本电脑、 个人电脑、 平板电脑、 个人数字助理或蓝牙等各种终 端。
在所述步骤 S110中， 第二通信节点在第一通信节点的无线覆盖范围内 在指定的时间范围内， 可同时或不同时的接收到若干个导频波束； 若干个 导频波束根据导频波束是否相同， 可分为若干种， 在本实施例中第二通信 节点在第一通信节点的导频波束的扫描下， 能接收到一种或多种导频波束。 所述导频波束为承载了导频信息的波束。 波束为经过了波束赋形处理的具 有特定形状的无线波。
在具体的实现过程中， 所述步骤 S120可以与所述步骤 S110的执行顺 序不固定。 所述配置信息包括所述导频波束的波束发射功率、 波束最大增 益、 波束宽度以及波束发送个数的至少其中之一的绝对值； 所述配置差异信息包括任意两种导频波束的波束发射功率差值、 波束 最大增益差值、 波束宽度差值以及波束发送个数差值的至少其中之一。
通过所述配置信息或配置差异信息， 就可知道两种导频波束传输到同 一第二通信节点在功率方面的差异。 所述配置信息为直接表征了每一种导 频波束的功率、 辐射方向、 辐射角度和 /或发送次数等信息。 而所述配置差 异信息， 表征的是至少两种导频波束之间的差异信息， 如发送功率的差值 等， 在具体实现过程中， 优选同一第一通信节点所发送的任意两种导频波 束的差异信息都相同， 以便减少配置差异信息的形成和发送， 减少信令的 交互。
在具体的实现过程中， 所述配置信息或所述配置差异信息至少可以采 用以下三种方法：
第一种 ： 从所接收的导频波束上提取所述配置信息或配置差异信息； 采用这种方法， 在接收导频波束的同时， 接收了配置信息或配置差异信息。
第二种： 从第一通信节点所发送的控制信令中， 接收所述配置信息或 配置差异信息； 具体的所述控制信令如广播信道或多播信道， 以便使多个 第二通信节点同时接收到配置信息或配置差异信息。 采用这种方法， 所述 步骤 S120的执行顺序可位于所述步骤 S110之前、 之后或与所述步骤 S110 同时执行。 束的映射关系， 获取所述配置信息或配置差异信息。 采用此种方法， 为第 二通信节点与第一通信节点预先进行协商， 第二通信节点在固定的时频资 源上接收导频波束， 根据所述映射关系就可以知道每一种导频波束的配置 信息或两种导频波束的配置差异信息， 这种方式可以将信令开销降低最低。
所述步骤 S130, 才艮据任意两种导频波束的配置信息或配置差异信息， 可计算出每一种导频波束的提升值。 具体地， 如导频波束 1 的发射功率为 Nl瓦， 导频波束 2的发射功率为 N2瓦， 可知导频波束 2相对于导频波束 1 的提升值为 N2-N1 瓦。 在接收到导频波束后， 第二通信节点可根据现有 方法计算每一中导频波束所对应的信道质量信息。 在比较两种导频波束的 信道质量信息， 要将导频波束 2 的信道质量信息减去所述提升值， 再与导 频波束 2的信道质量信息进行比较， 从而获得更加精确的比较结果。
在本实施例所述的方法中， 才艮据第二通信节点在第一通信节点的分布 位置不同， 发送多种配置有差异的导频波束， 从而能提升第一通信节点的 功率及空间资源有效利用率。 在具体的实现过程中， 所述第二通信节点在 选定出最佳的一种或多种导频波束后， 对应的波束即可作为通信的波束， 第二通信节点可以返回导频波束的索引等信息以方便后续第一通信节点确 定与第二通信节点进行通信的波束。

步骤 S230: 发送所述导频波束；
步骤 S240: 发送每种导频波束的配置信息或任意两种所述导频波束的 配置差异信息。
