技术领域Technical field

本申请涉及通信领域，特别涉及一种数据传输的方法和设备。The present application relates to the field of communications, and in particular, to a method and device for data transmission.

背景技术Background technique

面向2020年及未来，移动互联网和物联网业务将成为移动通信发展的主要驱动力。第五代移动通信技术(5th-Generation，5G)将满足人们在居住、工作、休闲和交通等领域的多样化业务需求，即使在密集住宅区、办公室、体育场、露天集会、地铁、快速路、高铁和广域覆盖等具有超高流量密度、超高连接数密度、超高移动性特征的场景，也可以为用户提供超高清视频、虚拟现实、云桌面、在线游戏等极致业务体验。与此同时，5G还将渗透到物联网及各种行业领域，与工业设施、医疗仪器、交通工具等深度融合，有效满足工业、医疗、交通等垂直行业的多样化业务需求，实现真正的“万物互联”。For 2020 and beyond, mobile Internet and IoT services will become the main driving force for the development of mobile communications. The 5th generation of mobile communication technology (5th-Generation, 5G) will meet the diverse business needs of people in the areas of residence, work, leisure and transportation, even in dense residential areas, offices, stadiums, open air gatherings, subways, expressways, High-speed rail and wide-area coverage, such as ultra-high traffic density, ultra-high connection density, and ultra-high mobility, can also provide users with ultra-high-definition video, virtual reality, cloud desktop, online games and other extreme business experiences. At the same time, 5G will penetrate into the Internet of Things and various industries, and integrate with industrial facilities, medical instruments, and transportation to effectively meet the diversified business needs of vertical industries such as industry, medical care, and transportation, and achieve real “ Everything is connected."

为满足上述各种业务需求，其中大规模天线技术(Massive-MIMO)被认为是5G的关键技术之一，它是唯一可以十倍、甚至百倍提升***容量的无线技术。相比于4/8天线***，大规模多天线技术能够通过不同维度(空域、时域、频域等)提升频谱效率和能量利用效率。In order to meet the above various business requirements, Massive-MIMO is considered to be one of the key technologies of 5G, and it is the only wireless technology that can increase system capacity ten times or even 100 times. Compared to 4/8 antenna systems, large-scale multi-antenna technology can improve spectral efficiency and energy utilization efficiency through different dimensions (space, time domain, frequency domain, etc.).

目前4/8天线***，一般采用开环或者闭环码本指示(codebook index)来实现上行多输入多输出(multiple-input multiple-output，MIMO)(最大4流)，一旦基站侧天线数增多(例如，16、32、64或256天线)、上行流数增多(如8、12、24、36或48流)，会使得流间相关性比较高，然而原标准中码本本身与实际上行信道可能会相差较远，在某些场景如果仍然采用开环或者原简单的码本指示方式，从而导致***整体性能降低。At present, 4/8 antenna systems generally use an open-loop or closed-loop codebook index to implement multiple-input multiple-output (MIMO) (maximum 4-stream), once the number of antennas on the base station side increases ( For example, 16, 32, 64, or 256 antennas, and the number of upstream streams (such as 8, 12, 24, 36, or 48 streams) will make the inter-stream correlation higher. However, the original standard codebook itself and the actual row channel It may be far from each other. In some scenarios, if the open loop or the original simple codebook indication method is still used, the overall performance of the system is degraded.

因此，如何提高***性能，成为亟待解决的问题。Therefore, how to improve system performance has become an urgent problem to be solved.

The embodiment of the present application is not limited to this.

网络侧设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络侧设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位***、PDA和/或用于在无线通信***100上通信的任意其它适合设备。The network side device 102 can communicate with a plurality of terminal devices (e.g., the terminal device 116 and the terminal device 122).

为了使得本发明实施例更容易理解，下面首先对本发明实施中涉及的一些描述加以说明，这些说明不应视为对本发明所需要保护的范围的限定。In order to make the embodiments of the present invention easier to understand, the following description of the embodiments of the present invention is to be construed as a limitation of the scope of the invention.

在MIMO传输场景下，为了消除数据流之间的部分或全部干扰，信号的发送端(例如，终端设备)需要使用预编码矩阵对发送信号进行预编码，发送端采用预编码处理后发送信号x和接收端接收到的接收信号y和之间的关系可以如下公式所示：In the MIMO transmission scenario, in order to eliminate some or all of the interference between the data streams, the transmitting end of the signal (for example, the terminal device) needs to precode the transmitting signal using the precoding matrix, and the transmitting end uses the precoding process to transmit the signal x. The relationship between the received signal y and the received signal received by the receiving end can be as follows:

y＝HWx+ny=HWx+n

其中，x为发送端的发送信号，y为接收端(例如，网络设备)的接收信号，H为信道矩阵，W为预编码矩阵，n表示噪声。Where x is the transmission signal of the transmitting end, y is the received signal of the receiving end (for example, the network device), H is the channel matrix, W is the precoding matrix, and n is the noise.

本申请实施例中主要涉及发送端(例如，上行传输时，该发送端为终端设备)如何确定预编码矩阵的方案。The embodiment of the present application mainly relates to a scheme for determining a precoding matrix by a transmitting end (for example, when the transmitting end is a terminal device in uplink transmission).

目前标准/产品支持网络设备(例如，基站BS)侧最大8天线上行接收，一般采用开环或者闭环码本指示(codebook index)来实现上行MIMO(最大4流)。At present, the standard/product support network device (for example, the base station BS) side has a maximum 8-antenna uplink reception, and generally adopts an open-loop or closed-loop codebook index to implement uplink MIMO (maximum 4-stream).

例如，如图2所示，在开环模式下，网络设备(例如，基站BS)侧不进行码本指示，直接对终端设备进行上行调度，多个终端设备(例如，图2中示出了4个终端设备)各自确定对应的预编码矩阵，并将数据映射至各天线并发送。For example, as shown in FIG. 2, in the open loop mode, the network device (for example, the base station BS) does not perform the codebook indication, and directly performs uplink scheduling on the terminal device, and multiple terminal devices (for example, shown in FIG. 2) Each of the four terminal devices determines a corresponding precoding matrix and maps the data to each antenna and transmits.

再例如，如图3所示，在闭环模式下，网络设备侧和终端设备侧预存储有相同的码本，基站侧首先根据上行信道状态通过下行控制信息DCI指示终端设备合适的预编码阈值的码本索引(codebook index)，终端设备根据码本索引查询码本获取预编码矩阵，并对发送信号进行预编码。For example, as shown in FIG. 3, in the closed loop mode, the network device side and the terminal device side pre-store the same codebook, and the base station side first indicates the appropriate precoding threshold of the terminal device by using the downlink control information DCI according to the uplink channel state. The codebook index is used by the terminal device to obtain a precoding matrix according to the codebook index query codebook, and precode the transmitted signal.

上述图2和图3的方案可以适用于网络设备侧天线数较少的情况，然而，一旦基站侧天线数增多(例如，16、32、64或256天线)、上行流数增多(如8、12、24、36或48流)，会使得流间相关性比较高，如果仍然采用开环模式，或者闭码本指示方式，终端设备使用的预编码矩阵可能与实际上行信道可能会相差较远，导致***整体性能降低。The schemes of FIG. 2 and FIG. 3 above can be applied to the case where the number of antennas on the network device side is small. However, once the number of antennas on the base station side increases (for example, 16, 32, 64, or 256 antennas), the number of upstream streams increases (for example, 8, 12, 24, 36 or 48 streams), the inter-stream correlation is relatively high. If the open-loop mode or the closed-code mode is still used, the precoding matrix used by the terminal device may be far from the actual channel. , resulting in a reduction in overall system performance.

鉴于已有方案的问题，本申请实施例巧妙地提出一种确定预编码的方法，为了避免终端设备使用与信道状态相差较大的预编码矩阵进行预编码，本申请实施例摒弃了现有开环或闭环码本指示的方案，而是采用网络设备直接将预编码矩阵反馈给终端的方案，同时由于预编码矩阵信息量较大，为了降低网络资源，提高***整体性能，如图4所示，本申请实施例通过网络设备发送压缩后的预编码矩阵，终端设备解压缩获取与信道状态对应的预编码矩阵。具体地，网络设备可以基于测量信道计算终端设备对应的上行传输的预编码矩阵；并将所有待发送的预编码矩阵进行压缩预处理，并向终端设备发送压缩后的预编码矩阵；终端设备收到的网络设备侧发送的信息后，解压缩出相应的预编码矩阵(反压缩过程)，并基于预编码矩阵进行上行MIMO编码，并将预编码后的数据发送至网络设备。In view of the problem of the existing solution, the embodiment of the present application subtly proposes a method for determining the precoding. In order to prevent the terminal device from precoding using a precoding matrix having a large difference in channel state, the embodiment of the present application discards the existing The scheme indicated by the ring or closed-loop codebook is a scheme in which the network device directly feeds back the precoding matrix to the terminal. At the same time, because the amount of information of the precoding matrix is large, in order to reduce network resources and improve overall system performance, as shown in FIG. In this embodiment, the compressed precoding matrix is sent by the network device, and the terminal device decompresses and obtains a precoding matrix corresponding to the channel state. Specifically, the network device may calculate a precoding matrix of the uplink transmission corresponding to the terminal device based on the measurement channel; perform pre-compression preprocessing on all precoding matrices to be sent, and send the compressed precoding matrix to the terminal device; After the information sent by the network device side is sent, the corresponding precoding matrix (decompression process) is decompressed, and uplink MIMO coding is performed based on the precoding matrix, and the precoded data is sent to the network device.

通过上述方案本申请实施例实现了终端侧采用更精确的预编码矩阵(例如与信道状态相近或一致的预编码矩阵)进行上行MIMO编码，解决了现有技术的问题，能够提高***性能。Through the foregoing solution, the embodiment of the present application implements uplink MIMO coding by using a more accurate precoding matrix (for example, a precoding matrix similar to or consistent with a channel state), which solves the problems of the prior art and can improve system performance.

以下，为了便于理解和说明，作为示例而非限定，以将本申请的传输信道状态信息的方法在通信***中的执行过程和动作进行说明。Hereinafter, for ease of understanding and explanation, the execution process and actions of the method for transmitting channel state information of the present application in the communication system will be described by way of example and not limitation.

For example, the uplink resource used by the user includes 20 M bandwidth, for a total of 110 RB. Assuming that the 5RB is a sub-band, the 20M bandwidth is a total of 22 sub-bands.

应理解，不同子带上下调度的层数可能不同，为了便于描述，本文中均以子带的上行调度的层数相同即均为r为例描述，但本申请实施例并不限于此。It should be understood that the number of layers that are scheduled in different sub-bands may be different.

情况一，该网络设备选取该左奇异矩阵和该右奇异矩阵的前N列，以及选取该特征值组成的对角矩阵的前N个特征值，得到压缩左奇异矩阵、压缩右奇异矩阵和压缩特征值，其中，该预编码矩阵信息包括该压缩左奇异矩阵、该压缩右奇异矩阵以及该压缩特征值，0<N<m，m表示该终端设备的发射天线数目；In the first case, the network device selects the left N singular matrix and the first N columns of the right singular matrix, and selects the first N eigenvalues of the diagonal matrix composed of the eigenvalues to obtain a compressed left singular matrix, a compressed right singular matrix, and a compression An eigenvalue, where the precoding matrix information includes the compressed left singular matrix, the compressed right singular matrix, and the compressed feature value, 0<N<m, where m represents the number of transmitting antennas of the terminal device;

情况二，该网络设备选取该左奇异矩阵和该右奇异矩阵的前N列，以及选取该对角矩阵的前N个特征值，得到压缩左奇异矩阵、压缩右奇异矩阵和压缩特征值；该网络设备对该压缩左奇异矩阵、压缩右奇异矩阵和压缩特征值进行量化，得到该预编码矩阵信息。In the second case, the network device selects the left singular matrix and the first N columns of the right singular matrix, and selects the first N eigenvalues of the diagonal matrix to obtain a compressed left singular matrix, a compressed right singular matrix, and a compressed eigenvalue; The network device quantizes the compressed left singular matrix, the compressed right singular matrix, and the compressed eigenvalues to obtain the precoding matrix information.

上述情况一和情况二的区别在于，情况一中，无需对压缩左奇异矩阵、该压缩右奇异矩阵以及该压缩特征值进行量化编码等，而是直接将这些信息作为预编码矩阵信息，网络设备可以直接将该预编码矩阵信息映射到时频资源上向终端设备发送，能够减少数据处理过程。在情况二中，网络设备需要经过压缩左奇异矩阵、该压缩右奇异矩阵以及该压缩特征值进行量编码等过程后将预编码矩阵信息发送至终端设备，经过编码等过程，能够提高数据的抗干扰能力、提供安全性等，能够提升网络性能。The difference between the first case and the second case is that in the first case, the compressed left singular matrix, the compressed right singular matrix, and the compressed eigenvalue need not be quantized, and the information is directly used as the precoding matrix information, and the network device The precoding matrix information can be directly mapped to the time-frequency resource and transmitted to the terminal device, which can reduce the data processing process. In case 2, the network device needs to send the precoding matrix information to the terminal device after the compressed left singular matrix, the compressed right singular matrix, and the compressed eigenvalue are encoded, and the data can be improved by encoding and the like. Interference ability, security, etc., can improve network performance.

例如，网络设备将新矩阵W进行SVD分解[U,S,V]＝SVD(W)；得到左奇异矩阵(或称为左奇异向量)U([m][m]),特征值组成的对角矩阵S([m][r*subband_num]),右奇异矩阵(或称为右奇异向量)V([r*subband_num][r*subband_num])。For example, the network device performs SVD decomposition of the new matrix W [U, S, V] = SVD (W); obtains a left singular matrix (or called left singular vector) U ([m] [m]), which is composed of eigenvalues. Diagonal matrix S([m][r*subband_num]), right singular matrix (or right singular vector) V([r*subband_num][r*subband_num]).

之后，网络设备分别取U和V的前N列，得到压缩左奇异矩阵U1,压缩右奇异矩阵V1，取S矩阵中前N个特征值(λ ₁,λ ₂,....λ _N)得到压缩特征值；仅将U1、V1、N个特征值(即压缩特征值)发送至终端侧，具体的，在情况一中网络设备直接发送U1、V1、压缩特征值，在情况二中网络设备需要对U1、V1、压缩特征值进行量化编码等过程后再发送。 After that, the network device takes the first N columns of U and V respectively, obtains the compressed left singular matrix U1, compresses the right singular matrix V1, and takes the first N eigenvalues (λ ₁ , λ ₂ , . . . λ _N ) in the S matrix. The compressed feature value is obtained; only the U1, V1, and N feature values (ie, the compressed feature value) are sent to the terminal side. Specifically, in case 1, the network device directly sends the U1, V1, and the compressed feature value, and in the second case, the network The device needs to perform the process of quantizing and encoding the U1, V1, and compression feature values before sending.

由于U1、V1和压缩特征值的数据量少于原W的数据量。因此，本申请实施例网络设备仅将U1、V1和压缩特征值发送至终端设备，能够减少传输的信息量，降低网络资源，提高***整体性能。Since the data amount of U1, V1 and the compressed feature value is smaller than the data amount of the original W. Therefore, the network device in the embodiment of the present application only sends the U1, V1, and the compressed feature values to the terminal device, which can reduce the amount of information transmitted, reduce network resources, and improve overall system performance.

It should be understood that, in the embodiment of the present application, the value of N may be a predetermined one, or the network device may be configured according to requirements, and the embodiment of the present application is not limited thereto.

假设N＝3，则获取压缩左奇异矩阵U1(8*3),压缩右奇异矩阵V1(44*3)的具体形式如下所示，压缩特征值包括λ ₁,λ ₂,λ ₃。 Assuming N=3, the compressed left singular matrix U1 (8*3) is obtained, and the specific form of the compressed right singular matrix V1 (44*3) is as follows, and the compressed feature values include λ ₁ , λ ₂ , λ ₃ .

在获取到压缩左奇异矩阵U1、右奇异矩阵V1和压缩特征值后，网络设备侧将U1,V1,压缩特征值通过一定的方式发送至终端侧。After acquiring the compressed left singular matrix U1, the right singular matrix V1, and the compressed feature value, the network device side sends the U1, V1, and compressed feature values to the terminal side in a certain manner.

发送方式1：根据上述情况一，网络设备将U1,V1,压缩特征值直接映射于时频域，发送至终端侧。例如，上述信息在频域上占用159个RE的资源。Transmission mode 1: According to the above case 1, the network device directly maps the U1, V1, and compressed feature values to the time-frequency domain, and sends the signal to the terminal side. For example, the above information occupies resources of 159 REs in the frequency domain.

其中，U1:占用8*3＝24个re资源，V1:占用44*3＝132个re资源，压缩特征值：占用 3个re资源。Among them, U1: occupies 8*3=24 re resources, V1: occupies 44*3=132 re resources, and compresses feature values: occupies 3 re resources.

Specifically, the IQ can be quantified using the following formula.

ceil(I*power(2,7))Ceil(I*power(2,7))

ceil(Q*power(2,7))Ceil(Q*power(2,7))

例如，针对数据0.583-0.213i而言，I＝0.583,可表示为01001011(0.583量化后数据是75，对应7bit是1001010)，Q＝-0.213,可表示为10011100(0.213量化后数据是28，对就7bit是0011100)。For example, for data 0.583-0.213i, I=0.583, which can be expressed as 010011011 (0.583 after quantization, the data is 75, corresponding to 7bit is 1001010), and Q=-0.213, which can be expressed as 10011100 (0.213 after quantization, the data is 28, Right on 7bit is 0011100).

应理解，本申请实施例中也可以采用其他方式对U1,V1,压缩特征值进行量化，只要能够将U1,V1,压缩特征值发送至终端设备侧即可，本申请实施例并不限于此。It should be understood that, in the embodiment of the present application, the U1, V1, and the compressed feature value may be quantized in other manners, as long as the U1, V1, and the compressed feature value can be sent to the terminal device side, the embodiment of the present application is not limited thereto. .

压缩方式二：Compression method two:

具体的，该网络设备对该多个预编码矩阵进行线性平均，获得平均预编码矩阵；该网络设备将该多个预编码矩阵分别与该平均预编码矩阵进行作差，获取该多个预编码矩阵中每个预编码矩阵对应的差值预编码矩阵；该网络设备对该平均预编码矩阵和该多个预编码矩阵中每个预编码矩阵对应的差值预编码矩阵进行量化处理，获取该预编码矩阵信息。Specifically, the network device performs linear averaging on the plurality of precoding matrices to obtain an average precoding matrix. The network device performs a difference between the plurality of precoding matrices and the average precoding matrix to obtain the multiple precodings. a difference precoding matrix corresponding to each precoding matrix in the matrix; the network device quantizes the average precoding matrix and the difference precoding matrix corresponding to each precoding matrix in the plurality of precoding matrices, and obtains the Precoding matrix information.

例如，子带的预编码矩阵为W _i(二维矩阵[m][r],其中，m表示终端侧上行发送天线，r表示上行调度的层数)，网络设备将所有子带预编码矩阵W _i,进行线性平均，获得平均预编码矩阵W _AVG。 For example, the precoding matrix of the subband is W _i (two-dimensional matrix [m][r], where m represents the terminal side uplink transmitting antenna, r represents the number of uplink scheduling layers), and the network device pre-codes all sub-band precoding matrices W _i , linear averaging is performed to obtain an average precoding matrix W _AVG .

W _AVG＝(W ₁+W ₂+...+Wsubband_num)/subband_num W _AVG = (W ₁ + W ₂ +... + Wsubband_num) / subband_num

之后，网络设备将矩阵W _i与矩阵W _AVG进行作差，得到差值预编码矩阵Wsub _i(i＝1～subband_num) After that, the network device performs a difference between the matrix W _i and the matrix W _AVG to obtain a difference precoding matrix Wsub _i (i=1 to subband_num).

Wsub _i＝W _AVG-W _i,i＝1～subband_num Wsub _i =W _AVG -W _i ,i=1~subband_num

最后，网络设备对W _AVG、Wsub _i(i＝1～subband_num)进行量化获取该预编码矩阵信息。 Finally, the network device quantizes W _AVG and Wsub _i (i=1 to subband_num) to obtain the precoding matrix information.

由于各个子带的预编码矩阵相似，Wsub _i中各个元素的值相对较小，因此仅需要少量bit表示Wsub _i信息。 Since the precoding matrices of the respective subbands are similar, the values of the respective elements in the Wsub _i are relatively small, so only a small number of bits are required to represent the Wsub _i information.

由于W _AVG、Wsub _i的信息的数据量少于原W的数据量。因此，本申请实施例仅将仅将W _AVG、Wsub _i的信息发送至终端设备，能够减少传输的信息量，降低网络资源，提高***整体性能。 The amount of data of the information of W _AVG and Wsub _i is less than the amount of data of the original W. Therefore, the embodiment of the present application only transmits the information of W _AVG and Wsub _i to the terminal device, which can reduce the amount of information transmitted, reduce network resources, and improve overall system performance.

下面结合图8具体的例子，详细描述本申请实施例中在压缩方式二中采用矩阵作差的方式对多个预编码矩阵进行压缩的具体方案。A specific scheme for compressing a plurality of precoding matrices in a compression mode in the second compression mode in the embodiment of the present application is described in detail below with reference to the specific example of FIG. 8.

具体而言，如图8所示，网络设备侧首先接收终端设备发送的上行测量导频信号，进行信道估计、上行预编码计算，获得各子带的预编码矩阵W _i，W _i矩阵维度为8*2。W _i的具体形式如下： Specifically, as shown in FIG. 8, the network device side first receives the uplink measurement pilot signal sent by the terminal device, performs channel estimation, and uplink precoding calculation, and obtains a precoding matrix W _{i of} each subband, and the W _i matrix dimension is 8*2. The specific form of W _i is as follows:

然后，网络设备将所有子带预编码矩阵W _i,进行线性平均，获得平均预编码矩阵W _AVG， Then, the network device performs linear averaging on all subband precoding matrices W _i to obtain an average precoding matrix W _AVG .

W _AVG＝(W ₁+W ₂+...+W ₂₂)/22 W _AVG = (W ₁ + W ₂ +... + W ₂₂ ) / 22

然后，网络设备对矩阵W _i和矩阵W _AVG进行比较，得到各个预编码矩阵对应的到差值 Then, the network device compares the matrix W _i and the matrix W _AVG to obtain a difference value corresponding to each precoding matrix.

预编码矩阵Wsub _i。 Precoding matrix Wsub _i .

Wsub _i＝W _AVG-W _i,i＝1～22,Wsub _i:8*2 Wsub _i =W _AVG -W _i ,i=1～22,Wsub _i :8*2

在获取到Wsub _i和W _AVG后，网络设备侧通过一定的方式将Wsub _i和W _AVG发送至终端侧。例如，对W _AVG、Wsub _i(i＝1～22)进行量化，由于各子带信息相近，因此Wsub _i和W _AVG相比，Wsub _i中各个元素的值相对较小，因此仅需要少量bit表示Wsub _i信息。 After acquiring Wsub _i and W _AVG , the network device side sends Wsub _i and W _AVG to the terminal side in a certain manner. For example, if W _AVG and Wsub _i (i=1 to 22) are quantized, since each sub-band information is similar, Wsub _i and W _AVG have relatively small values of each element in Wsub _i , so only a small number of bits are needed. Indicates Wsub _i information.

具体的，本申请实施例中可以通过以下方式进行量化：对W _AVG中共8*2,16个元素的实部/虚部进行8bit量化，1bit表示符号位(例如，0表示正数，1表示负数)，7bit表示量化数据；对Wsub _i(i＝1～22)，每个子带16个元素的实部/虚部进行4bit量化，1bit表示符号位，3bit表示数据位。则量化信息的长度为：W _AVG:8*2*2(IQ)*8bit＝256bit；Wsub _i(i＝1～22):8*2*2(IQ)*4bit*22(subband)＝2816bit；量化后的总信息长度Total_len＝256+2816＝3072bit。 Specifically, in the embodiment of the present application, the quantization may be performed by performing 8-bit quantization on the real/imaginary part of the 8 A2 and 16 elements in the W _AVG , and 1 bit represents the sign bit (for example, 0 represents a positive number, and 1 represents Negative), 7 bits represent quantized data; for Wsub _i (i = 1 to 22), the real/imaginary part of each sub-band 16 elements is 4-bit quantized, 1 bit represents a sign bit, and 3 bit represents a data bit. Then the length of the quantized information is: W _AVG : 8 * 2 * 2 (IQ) * 8 bit = 256 bit; Wsub _i (i = 1 ~ 22): 8 * 2 * 2 (IQ) * 4 bit * 22 (subband) = 2816 bit The total information length after quantization is Total_len=256+2816=3072bit.

应理解，上述对W _AVG、Wsub _i(i＝1～22)的量化的方式仅是示例性的，在实际应用中也可以采用其他量化方式进行量化，由于Wsub _i是相对值，因此数值较小，对其量化仅需少量的量化bit。 It should be understood that the above-mentioned methods for quantifying W _AVG and Wsub _i (i=1 to 22) are merely exemplary. In practical applications, other quantization methods may also be used for quantization. Since Wsub _i is a relative value, the value is compared. Small, only a small amount of quantized bits are needed for its quantization.

可选地，作为另一实施例，在网络设备发送量化后的W _AVG、Wsub _i(i＝1～22)的情况下，为了使得终端设备能够获取该预编码矩阵信息。该方法还包括网络设备发送量化模式指示信息。也就是说，网络设备向终端设备发送量化模式指示信息以及量化后的信息。具体的，如图9所示，网络设备发送的量化模式指示信息可以包括量化模式以及量化后总长度，网络设备发送的量化后的信息可以包括W _AVG、Wsub _i(i＝1～22)的量化信息。 Optionally, as another embodiment, in a case where the network device sends the quantized W _AVG and Wsub _i (i=1 to 22), in order to enable the terminal device to acquire the precoding matrix information. The method also includes the network device transmitting the quantization mode indication information. That is, the network device transmits the quantization mode indication information and the quantized information to the terminal device. Specifically, as shown in FIG. 9, the quantization mode indication information sent by the network device may include a quantization mode and a total length after quantization, and the quantized information sent by the network device may include W _AVG and Wsub _i (i=1 22 22).

可选地，作为另一实施例，该压缩模式指示信息和该预编码矩阵信息是该网络设备一起发送或者独立发送的。Optionally, as another embodiment, the compressed mode indication information and the precoding matrix information are sent together or independently by the network device.

例如，以支持上行24流的ULMIMO场景为例，假设每个UE为2流，则可以共有12个进行UL MIMO传输。网络设备对每个终端设备待发送的所有预编码矩阵进行压缩，并将压缩模式和压缩后的数据信息(即预编码矩阵信息)发送至终端侧。For example, taking an UL MIMO scenario supporting uplink 24 streams as an example, assuming that each UE is 2 streams, a total of 12 UL MIMO transmissions can be performed. The network device compresses all precoding matrices to be transmitted by each terminal device, and transmits the compressed mode and the compressed data information (ie, precoding matrix information) to the terminal side.

具体的，压缩模式的具体说明可以如下表1所示，压缩模式指示信息可以为6bit的数据，其中，前面的2bit，即压缩模式(前2bit)用于表示上文描述的压缩方式一或压缩方式二对应的编号；后面的4bit，即压缩模式(后4bit)用于表示N的取值，其中，压缩模式0或1(前2bit)对应上文中的压缩方式一，在压缩模式0(前2bit)中，直接将压缩后信息映射至频域发送侧终端侧。在压缩模式1(前2bit)中，对压缩后信息量化后再发送至终端侧。压缩模式2(前2bit)，对应上文中的压缩方式二，在压缩模式2(前2bit)中，压缩后信息量化发送至终端侧，由于在压缩方式二中不涉及N的取值，因此，这种模式下，压缩模式(后4bit)是无效的为缺省值(Default)。Specifically, the specific description of the compressed mode may be as shown in Table 1 below, and the compressed mode indication information may be 6 bits of data, wherein the previous 2 bits, that is, the compressed mode (first 2 bits) is used to represent the compression mode or compression described above.
