传统的波束赋形技术中，首先采用EBB(Eigenbased Beamforming)技术进行单用户波束赋形，以实现单用户的传输层的正交化，从而达到增益最大化，再基于用户间的信道正交化，抑制用户间的信道干扰。In the traditional beamforming technology, EBB (Eigenbased Beamforming) technology is first used for single-user beamforming to realize the orthogonalization of the transmission layer of a single user, so as to maximize the gain, and then based on the channel orthogonalization between users , to suppress channel interference between users.

然而，用户间的信道正交化过程会破坏单用户的传输层之间的正交性，从而使得各传输层之间产生干扰，降低通信质量。However, the channel orthogonalization process between users will destroy the orthogonality between transmission layers of a single user, thereby causing interference between transmission layers and reducing communication quality.

在实际应用中，通过波束赋形，可以产生指向终端设备的专用波束，不同终端设备的波束在空间进行区分，使得不同终端设备能在同一小区同时同频的进行数据通信，从而有效得提高时频资源的利用率。In practical applications, beamforming can generate dedicated beams pointing to terminal devices, and the beams of different terminal devices are distinguished in space, so that different terminal devices can perform data communication at the same frequency and at the same time in the same cell, thereby effectively improving the time Utilization of frequency resources.

其中，波束赋形是一种有效在MU-MIMO系统中实现用户空分复用的技术手段，可以使得配对终端设备能同时同频的进行数据通信，提高时频资源的利用率。Among them, beamforming is a technical means to effectively realize user space division multiplexing in the MU-MIMO system, which can enable paired terminal devices to perform data communication at the same time and frequency, and improve the utilization rate of time-frequency resources.

在传统的MU-MIMO波束赋形方法中，通常是先采用EBB进行单用户的波束赋形，即对每个终端设备对应的信道的赋形空间进行正交分解，使得信道中的各传输层之间正交，从而达到增益最大化；再基于用户间的信道正交化，对不同终端设备对应的传输层进行正交化处理，从而抑制用户间的信道干扰。In the traditional MU-MIMO beamforming method, EBB is usually used first to perform single-user beamforming, that is, to perform orthogonal decomposition on the shaping space of the channel corresponding to each terminal device, so that each transmission layer in the channel Orthogonal between them, so as to maximize the gain; based on the channel orthogonalization between users, the transmission layer corresponding to different terminal devices is orthogonalized, so as to suppress the channel interference between users.

然而，此波束赋形算法将单用户的最大增益子信道选取和用户间的信道去相关过程割裂开来，用户间的信道正交化过程会破坏单用户的传输层之间的正交性，从而使得各传输层之间产生干扰，降低通信质量。However, this beamforming algorithm separates the maximum gain subchannel selection of a single user from the channel decorrelation process between users, and the channel orthogonalization process between users will destroy the orthogonality between the transmission layers of a single user. As a result, interference occurs between the various transmission layers and communication quality is reduced.

For terminal device 1, its jth channel space is the current channel space of channel 1; for terminal device 2, its jth channel space is the current channel space of channel 2; for terminal device 3, its jth channel space is the current channel space of channel 3 channel space.

在一些实施例中，每个信道中有多个传输层。示例性的，信道1包括3个传输层，分别为：传输层a1、传输层a2和传输层a3，信道2包括2个传输层，分别为：传输层b1、传输层b2；信道3包括4个传输层，分别为：传输层c1、传输层c2、传输层c3和传输层c4，也就是说，这3个终端设备对应的传输层的传输层个数最大值为4，即J的值为4，j为区间[1,4]中的任一整数。In some embodiments, there are multiple transport layers per channel.

具体的，采用传输层间的信道正交技术，获取每个传输层的目标赋形空间。示例性的，以j＝1为例，在本步骤中，在确定每个终端设备对应的第1信道空间之后，采用信道正交技术，分别确定信道1中传输层a1对应的目标赋形空间、信道2中传输层b1对应的目标赋形空间，以及信道3中传输层c1对应的目标赋形空间，从而保证传输层a1对应的目标赋形空间、传输层b1对应的目标赋形空间以及传输层c1对应的目标赋形空间之间的正交化。Specifically, the channel orthogonal technology between transmission layers is used to obtain the target shaping space of each transmission layer. Exemplarily, taking j=1 as an example, in this step, after determining the first channel space corresponding to each terminal device, the channel orthogonal technology is used to respectively determine the target shaping space corresponding to the transmission layer a1 in channel 1 , the target shaping space corresponding to the transport layer b1 in channel 2, and the target shaping space corresponding to the transport layer c1 in channel 3, so as to ensure the target shaping space corresponding to the transport layer a1, the target shaping space corresponding to the transport layer b1, and Orthogonalization between the target shaped spaces corresponding to the transmission layer c1.

需要说明的是，在每个传输层的目标赋形空间的计算过程中，均采用信道正交技术，可以保证每个终端设备的传输层之间的信道正交，从而防止各传输层之间产生干扰，有助于提升通信质量。It should be noted that in the calculation process of the target shaped space of each transmission layer, the channel orthogonal technology is used to ensure that the channels between the transmission layers of each terminal device are orthogonal, thereby preventing the Interference can help improve communication quality.

在一些实施例中，当j等于1时，确定第j信道空间为终端的初始信道空间。In some embodiments, when j is equal to 1, the jth channel space is determined as the initial channel space of the terminal.

其中，初始信道空间是由网络设备对信道进行测量得到的。Wherein, the initial channel space is obtained by the network device measuring the channel.

在另一些实施例中，当j大于1时，需要从终端设备的初始信道空间中剥离掉前j-1个传输层已经选择了的赋形空间，从而确定当前剩余的信道空间作为第j信道空间。In other embodiments, when j is greater than 1, it is necessary to strip off the shaped space selected by the first j-1 transmission layers from the initial channel space of the terminal device, so as to determine the current remaining channel space as the jth channel space.

In addition, through the channel-orthogonal technology between channels, the channel spaces between different transmission layers of the same terminal device can also be guaranteed to be orthogonal (for example, the target shaping space corresponding to the second transmission layer and the target shaping space corresponding to the first transmission layer Shape space is orthogonal, the target shape space corresponding to the third transmission layer is orthogonal to the target shape space corresponding to the first transmission layer and the second transmission layer), and then the interference between the transmission layers can be prevented to the greatest extent, and the communication quality.
