Detailed ways

In order to understand the features and technical content of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present invention.

Before describing in detail the channel state information transmission method provided by the embodiment of the present invention, a brief description of the codebook in the related technology is first given.

In the 5th Generation (5G) New Radio (NR) system, a terminal device reports a Type II codebook for characterizing CSI to a network device. Type Ⅱ codebook Type Ⅱ codebook is independently encoded in the frequency domain (that is, each subband); due to the high spatial quantization accuracy of Type Ⅱ codebook, terminal equipment needs to feed back a large amount of channel information to network equipment, occupying a lot of network resources and increasing Network overhead.

TypeⅡ codebook is expressed by the following formula:

Among them, W ₁ represents 2L spatial beams (beam),

Represents M discrete Fourier Transform (DFT) basis vectors,

Represents the weighting coefficient of arbitrary space beam and frequency domain DFT vector pairs. A schematic view of a space-based vector (SD basis) of the two polarization directions W ₁ comprises, as shown in FIG. 1, SD basis even a direction of polarization and respectively pol0 pol1.

In related technologies, terminal equipment reports

The method includes: the number of SD basis configured by the network device, and the number of SD basis is represented by L. Alternatively, the number of FD basis configured by the network device is used, and the number of FD basis is represented by M, where M is a parameter related to the frequency domain bandwidth reported by the terminal device to the network device. Alternatively, the network device adopts the maximum number of non-zero coefficients K ₀ configured by the network device to restrict

The maximum number of reported elements. Or, determined by bitmap and/or instruction information

The number of non-zero elements in, and/or non-zero elements in

In the location. Or, determined by one or more sets of parameters including amplitude and phase

The quantization accuracy in the medium; for the two polarization directions, independent differences are used, and the position of the strongest coefficient is indicated by SCI.

Among them, the value of M is equal to

The number of columns, M FD basis is selected by the terminal equipment from the N3 column DFT vector, the schematic diagram of selecting the FD basis in the DFT vector, as shown in Figure 2, select the sequence numbers from the 13 columns of DFT vectors as 0, 4 and The three columns of 9 (shown by the shadow in Figure 2) are used as the FD basis. The value of 2L is equal to

The number of rows, L SD basis is selected by the terminal device from N1N20102 DFT vectors.

In the related technology, the SCI indicates the strongest non-zero coefficient, and the bit width of the SCI indicating the strongest non-zero coefficient includes two solutions. The first is that the bit width of the SCI is

or

The second is that the bit width of SCI is

Among them, K ₀ is the number of maximum non-zero coefficients in each layer; 2K ₀ is the number of maximum non-zero coefficients in all layers. K ₀ = β2LM, β is the largest non-zero coefficient factor, used to determine the number of the largest non-zero coefficient, β is configured by the network device through high-level signaling. L is the number of SD basis, 2L is the number of SD basis corresponding to the two polarization directions, and L is configured by the network equipment through high-level signaling.

The bit width of SCI is

At this time, it is necessary to determine the position of the non-zero coefficient by cyclic shift. The bit width of SCI is

When, a schematic diagram of the position of the strongest non-zero coefficient is shown in Figure 3; for the maximum K ₀ =20 non-zero coefficients, 5 bits are used to determine the position of the strongest non-zero coefficient, as shown in Figure 3 with a dot Filling position. The bit width of SCI is

When, based on Figure 3, select the 3rd, 4th, 5th, 6th, and 7th columns of the M DFT vectors to cyclically shift to the 0th, 4th, 5th, 6th, and 7th columns in another schematic diagram of the position of the strongest non-zero coefficient as shown in Figure 4

Columns

1, 2, 6, and 7, and use the 2 bits in column 0 to indicate the number of SCI rows; the position filled with dots in Figure 4 is the position of the strongest non-zero coefficient.

In related technologies, when the network equipment configuration terminal device adopts the first of the two schemes of the above-mentioned SCI bit width, in some scenarios, the SCI bit width adopts the first scheme compared with the second scheme. The overhead of the CSI fed back by the terminal device to the network device is small; however, in other scenarios, the bit width of the SCI adopts the first solution compared to the second solution, and the overhead of the CSI fed back by the terminal device to the network device is large.
