Detailed Description
So that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the present invention will be rendered by reference to the appended drawings, which are included for purposes of illustration and not limitation.
Before describing the channel state information transmission method provided by the embodiment of the present invention in detail, a codebook in the related art is briefly described.
In a New Radio (NR) system with a fifth Generation (5th Generation, 5G), a terminal device reports a Type ii codebook for characterizing CSI to a network device. The Type II codebook is independently coded in a frequency domain (namely each sub-band); due to the fact that the space quantization precision of the Type II codebook is high, the terminal device needs to feed back a large amount of channel information to the network device, a large amount of network resources are occupied, and network overhead is increased.
The Type II codebook is represented by the following formula:
wherein, W1Representing 2L spatial beams (beams),represents M Discrete Fourier Transform (DFT) basis vectors,representing the weighting coefficients of arbitrary spatial beam, frequency domain DFT vector pairs. W1The two polarization directions of (a) include space basis vectors (SD basis), as shown in fig. 1, and the SD basis of the two polarization directions are pol0 and pol1, respectively.
In the related art, terminal equipment reportsThe method comprises the following steps: the number of SDbases configured by the network device is adopted, and the number of SD bases is represented by L. Or, the number of FD bases configured by the network device is adopted, where the number of FD bases is represented by M, and M is a parameter related to a frequency domain bandwidth reported by the terminal device to the network device. Or, adopting the number K of the maximum nonzero coefficients configured by the network equipment0To restrainReporting a maximum number of elements. Alternatively, the determination may be made through a bitmap and/or indication informationThe number of non-zero elements, and/or the number of non-zero elements inOf (c) is used. Alternatively, the determination is made by one or more sets of parameters including amplitude and phaseThe quantization accuracy of (1); the location of the strongest coefficient is indicated by the SCI using independent differences for the two polarization directions.
Wherein the value of M is equal toM FD bases are selected by the terminal device from N3 DFT vectors, and as shown in fig. 2, three columns (shaded in fig. 2) with serial numbers 0, 4 and 9 are selected from 13 DFT vectors as FD bases. 2L is equal toL SD bases are selected by the terminal device from the N1N20102 DFT vectors.
In the related art, the SCI indicates the strongest non-zero coefficient, and the bit width fixation of the SCI indicating the strongest non-zero coefficient comprises two schemes, wherein the first scheme is that the bit width of the SCI is SCIOrThe second is that the bit width of SCI isWherein, K0Is the number of largest non-zero coefficients of each layer; 2K0Is the number of largest non-zero coefficients of all layers. K0β 2LM, <tttranslation = β ">tβ <t/t >tis the maximum non-zero coefficient factor for determining the number of maximum non-zero coefficients β is configured by the network device through high layer signaling.l is the number of SD bandwidths, 2L is the number of SD bandwidths for 2 polarization directions, L is configured by the network device through high layer signaling.
The bit width of SCI isThe position of the non-zero coefficient needs to be determined by cyclic shifting. The bit width of SCI isA schematic diagram of the position of the strongest non-zero coefficient, as shown in fig. 3; for maximum K0The position of the strongest non-zero coefficient is determined with 5 bits, as in fig. 3 filled with dots, for 20 non-zero coefficients. The bit width of SCI isThen, based on fig. 3, select 3 rd, 4 th, 5th, 6 th, 7 th columns of the M DFT vectors to cyclically shift to, for example, 0 th, 1 th, 2 th, 6 th, 7 th columns of another schematic diagram of the position of the strongest non-zero coefficient shown in fig. 4, and indicate the row number of SCI by using 2 bits in the 0 th column; the positions filled with dots as in fig. 4 are the positions of the strongest non-zero coefficients.
In the related art, when the network device configures the terminal device to adopt the first of the two schemes of the bit width of the SCI, in some scenes, the bit width of the SCI adopts the first scheme, compared with the second scheme, the cost of the CSI fed back to the network device by the terminal device is small; however, in other scenarios, the bit width of the SCI is larger in the first scheme than in the second scheme, and the overhead of CSI fed back to the network device by the terminal device is larger.
