背景技术Background technique

协作多点(coordination multiple point，CoMP)传输是一种用于解决小区间干扰问题并提升小区边缘用户吞吐量的方法。在CoMP传输场景中，多个网络设备可以同时与一个终端设备进行通信，为了实现多个网络设备的协作传输，该多个网络设备中的主协作网络设备需要知道每个网络设备到终端设备的下行信道的信道情况。Coordination multiple point (CoMP) transmission is a method for solving inter-cell interference problems and improving cell edge user throughput. In a CoMP transmission scenario, multiple network devices can simultaneously communicate with one terminal device. To achieve coordinated transmission of multiple network devices, the primary cooperative network device of the multiple network devices needs to know each network device to the terminal device. The channel condition of the downlink channel.

信道状态信息(channel state information，CSI)用于表示通信***中通信链路的信道属性，在下行传输中，网络设备可以发送信道状态信息参考信号(channel state information reference signal，CSI-RS)，用于终端设备对下行信道进行测量。一般来说，终端设备可以将测量到的CSI反馈给网络设备，从而使网络设备获知下行信道的信道状态。The channel state information (CSI) is used to indicate the channel attribute of the communication link in the communication system. In the downlink transmission, the network device can transmit a channel state information reference signal (CSI-RS). The terminal device measures the downlink channel. Generally, the terminal device can feed back the measured CSI to the network device, so that the network device knows the channel state of the downlink channel.

具体地，在现有的CSI测量方法中，网络设备向终端设备指示CSI-RS资源和码本，该终端设备基于该CSI-RS资源和码本进行CSI测量，得到该信道的CSI。Specifically, in the existing CSI measurement method, the network device indicates a CSI-RS resource and a codebook to the terminal device, and the terminal device performs CSI measurement based on the CSI-RS resource and the codebook to obtain CSI of the channel.

然而，在CoMP传输场景中，当多个网络设备同时与终端设备进行数据传输时，不同信道之间可能会相互干扰，因此，采用现有方法进行CSI测量，CSI的精确度较低，从而影响数据传输性能。However, in a CoMP transmission scenario, when multiple network devices simultaneously transmit data with the terminal device, different channels may interfere with each other. Therefore, using existing methods for CSI measurement, the accuracy of CSI is low, thereby affecting Data transfer performance.

在CoMP传输场景中，网络设备通常需要参考终端设备反馈的CSI来确定合理的传输方案和调度策略。终端设备可根据网络设备所指示的参考信号资源，例如，信道状态信息参考信号(channel state information reference signal，CSI-RS)资源，进行CSI测量和反馈。In a CoMP transmission scenario, a network device usually needs to refer to the CSI fed back by the terminal device to determine a reasonable transmission scheme and scheduling policy. The terminal device may perform CSI measurement and feedback according to a reference signal resource indicated by the network device, for example, a channel state information reference signal (CSI-RS) resource.

可选地，本申请实施例中所述的CSI包括但不限于下列信息中的至少一项：预编码矩阵指示(precoding matrix indicator，PMI)、秩指示(rank indication，RI)和信道质量指示(channel quality indicator，CQI)、CSI-RS资源指示(CSI-RS resource indicator，CRI)和层指示(layer indication，LI)中的至少一项，本申请实施例对此不作限定。Optionally, the CSI described in the embodiment of the present application includes, but is not limited to, at least one of the following information: a precoding matrix indicator (PMI), a rank indication (RI), and a channel quality indicator ( The channel quality indicator (CQI), the CSI-RS resource indicator (CRI), and the layer indication (LI) are not limited in this embodiment of the present application.

假设网络设备1和网络设备2协作传输，终端设备根据网络设备1发送的CSI-RS估计信道矩阵H1，根据网络设备2发送的CSI-RS估计信道矩阵H2，网络设备1配置了码本W1，网络设备2配置了码本W2。其中，W1＝[v ₁₁ v ₁₂ … v _1n]，W2＝[v ₂₁ v ₂₂ … v _2m]，v _jk表示可选预编码矩阵，1≤j≤n,1≤k≤m。 Assuming that the network device 1 and the network device 2 are cooperatively transmitted, the terminal device estimates the channel matrix H1 according to the CSI-RS transmitted by the network device 1, and the network device 1 configures the codebook W1 according to the CSI-RS estimated channel matrix H2 transmitted by the network device 2. The network device 2 is configured with a codebook W2. Where W1=[v ₁₁ v ₁₂ ... v _1n ], W2=[v ₂₁ v ₂₂ ... v _2m ], v _jk represents an optional precoding matrix, 1≤j≤n, 1≤k≤m.

可选地，W1中可选预编码矩阵的个数n ₁例如可以根据W1的码本参数信息和W1的码本子集限制信息确定，W2中可选预编码矩阵的个数n ₂例如可以根据W2的码本参数信息和W2码本子集限制信息确定。 Optionally, the number n ₁ of optional precoding matrices in W1 may be determined according to, for example, codebook parameter information of W1 and codebook subset restriction information of W1, where the number n ₂ of optional precoding matrices in W2 may be, for example, It is determined according to the codebook parameter information of W2 and the W2 codebook subset restriction information.

现有技术中，该终端设备在H1×W1的等效信道下，在W1中确定第1个预编码矩阵，例如v ₁₁，该预编码矩阵v ₁₁使网络设备1的吞吐率最大；该终端设备在H2×W2的等效信道下确定第2个预编码矩阵，例如v ₂₁，该预编码矩阵v ₂₁使网络设备2的吞吐率最大。 In the prior art, the terminal device at an equivalent channel H1 × W1, and W1 is determined in a first pre-coding matrix, e.g. v _11, v ₁₁ the precoding matrix so that a maximum throughput of the network device; the terminal the second device determines the precoding matrix at the equivalent channel H2 × W2, e.g. v _21, v ₂₁ the precoding matrix so that the maximum throughput of the network device 2.

然而，在CoMP传输场景中，网络设备1和网络设备2的2个预编码矩阵之间会互相干扰，因此，网络设备1和网络设备2的***吞吐率总和比较低，即CSI的测量精确度较低，从而会影响数据传输性能。However, in the CoMP transmission scenario, the two precoding matrices of the network device 1 and the network device 2 interfere with each other. Therefore, the sum of the system throughput of the network device 1 and the network device 2 is relatively low, that is, the measurement accuracy of the CSI. Lower, which affects data transfer performance.

有鉴于此，本申请提供一种信道状态信息的测量方法，有利于提高CSI测量的精确度，进而提高数据传输性能。In view of this, the present application provides a method for measuring channel state information, which is advantageous for improving the accuracy of CSI measurement, thereby improving data transmission performance.
