Description

Channel state information CSI report transmission method, terminal and network equipment

Technical field

The present invention relates to the field of communication technology, and in particular, to a transmission method of channel state information CSI report, a terminal and a network device.

Background technique

In the wireless communication system, the feedback of Channel State Information (CSI) has been enhanced. There are two types of CSI feedback: Type 1 and Type 2. Among them, Type 2 uses spatial orthogonal baseline linear combination (LC) to approximate CSI, such as the eigenvalue vector of the channel. Specifically, L orthogonal beams are selected from the oversampled 2-Dimentional Discrete Fourier Transform (2D DFT) beams, and the L orthogonal beams in each layer (or each eigenvalue vector) are calculated. ) corresponding combination coefficient (complex number), and quantize its amplitude value, phase value and/or phase angle value. Among them, L is configured by the network device, and the selection of orthogonal beams is based on bandwidth and applies to all ranks, that is, to all layers. The amplitude quantization of the combined coefficient can be configured as bandwidth quantization or bandwidth quantization and subband quantization, where subband amplitude (subband Amplitude) indicates bandwidth quantization when it is false (false), and bandwidth quantization and subband amplitude when it is true (true) indicates bandwidth quantization and subband quantization. Subband quantization. The phase angle quantization of the combined coefficients is completed on each sub-band.

Further, the CSI report corresponding to CSI feedback type 2 can be written as a 2L×R matrix with a codebook at frequency domain granularity m.

If the combined coefficients at all frequency domain granularities are cascaded together, the precoding matrix of layer r in the frequency domain can be obtained, and the precoding matrix can be written as a 2L×M matrix.

In order to reduce CSI feedback overhead, frequency domain compression using frequency domain correlation, time domain compression based on sparsity of time domain impulse response, and frequency domain difference can be used to compress the 2L×M matrix into 2L×K compression. matrix.

Specifically, the type 2 CSI report includes a first part (part1) and a second part (part2), where part1 has a fixed payload size and specifically includes: Rank Indication (RI), Channel Quality Indication (ChannelQuality Indication, CQI) and an indication of the number of non-zero amplitude combining coefficients for each layer bandwidth. part2 includes a Precoding Matrix Indicator (PMI). In the CSI report, part1 and part2 are encoded separately, and the payload size of part2 is determined based on the information of part1.

When the CSI report is transmitted on the Physical Uplink Share Channel (PUSCH), because the network device cannot predict the size of the CSI report, especially the payload size of part2 in the CSI report, the PUSCH resources allocated by the network device may not be able to accommodate the CSI. At this time, the terminal can discard the subband CSI information to ensure that the CSI report can be placed in the corresponding network configured uplink resources. However, for the codebook based on Fourier transform compression in New Radio (NR), the information put into the CSI report no longer has the concept of subbands. Therefore, the existing discarding scheme cannot be used, so the network equipment After receiving the CSI report, it is impossible to determine the part of the CSI discarded by the terminal. In this way, the network device will not be able to accurately judge the channel condition based on the CSI report, resulting in deterioration of CSI feedback performance.

Please refer to FIG. 1 , which shows a block diagram of a wireless communication system to which embodiments of the present invention are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be called a terminal device or a user terminal (User Equipment, UE).

The base station may communicate with the terminal 11 under the control of a base station controller, which in various examples may be part of the core network or certain base stations. Some base stations can communicate control information or user data with the core network through backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly through a backhaul link, which may be a wired or wireless communication link. Wireless communication systems can support operations on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies.

In existing wireless communication systems, type 2 CSI reports include the first part (part1) and the second part (part2), where part1 has a fixed payload size, specifically including: Rank Indication (RI), channel quality indicator (Channel Quality Indication, CQI) and an indication of the number of non-zero amplitude combination coefficients for each layer bandwidth. part2 includes a Precoding Matrix Indicator (PMI). In the CSI report, part1 and part2 are encoded separately, and the payload size of part2 is determined based on the information of part1.

The two-level codebook of CSI report at frequency domain granularity m can be written as:

Among them, N ₁ and N ₂ are the number of ports of the CSI Reference Signal (CSI-RS) in two dimensions respectively, R is the rank number or the number of layers; b' _l is the positive beam vector composed of 2D-DFT. Intersection vector, c _{l, r} (m) is the combination coefficient of the l-th orthogonal beam vector of layer r on frequency domain granularity m, r=1,2,…,R, l=1,2,…,2L , L is the number of selected orthogonal beams. The frequency domain granularity can be a subband or a resource block (RB). Taking the frequency domain granularity as a unit, the broadband can be divided into M frequency domain resources.

If the combined coefficients of all subbands are cascaded together, the precoding matrix of layer r in the frequency domain can be obtained. This precoding matrix is the precoding matrix of a certain layer in the broadband (or called the frequency domain), That is, by cascading all the combination coefficients at the frequency domain granularity together, the precoding matrix of layer r in the frequency domain can be obtained. The precoding matrix can be written as a 2L×M matrix, expressed as follows:

Among them, c _l,r (m) is the combination coefficient of the l-th orthogonal beam vector of layer r on frequency domain granularity m. The l-th row in W _2,r represents the combined coefficient matrix of the beam vector b′ _l at all frequency domain granularities, which is expressed as follows:

Due to the existence of frequency domain correlation, the above-mentioned coefficient matrices (W _2,r ) _2L×M can be further compressed in the frequency domain; on the other hand, the sparsity of the impulse response of the time domain channel can be compressed in the time domain.

The compression matrix is: extract elements from the product of the precoding matrix and the initial vector matrix of the orthogonal basis, and form a 2L×K matrix composed of the extracted elements. K is a value less than M. K can be configured by the network device, or It can be stipulated in the agreement, or it can be determined independently by the terminal. For example, spatial compression of CSI feedback type 2 is used to transform W _2,r into W ₃ , that is From the orthogonality of W ₃ />

Assume that W ₃ is determined as an M×M-dimensional inverse discrete Fourier Transform (IDFT) matrix, which is equivalent to transforming the combined coefficients of the frequency domain into the time domain, that is, transforming W _2,r :

If the spatially compressed frequency domain coefficients are sparse in the time domain, then only a small number of time domain coefficients with large amplitudes can be fed back, and the other time domain coefficients can be zero. Assuming that only the K time domain coefficients with the largest amplitudes after IDFT transformation are fed back, then Extract K columns from , and get/>

The number of complex numbers that need to be fed back in each layer is reduced from (2L-1)M to (2L)k _i , and the selected K1 non-zero coefficient numbers are fed back to achieve time domain compression, where The selected orthogonal basis vector matrix corresponding to the corresponding position is/>

Or, suppose includes the selected k _r optimal orthogonal vectors, where k _r <M, then W _2,r can be approximately restored. For example/> Including the selected k _r orthogonal DFT vectors, or the K right main singular vectors decomposed by singular value decomposition (SVD), etc. Transform W _2,r to get:

Therefore, the content that needs feedback changes from the 2L×M dimension W _2,r to the 2L×k _r dimension. And the numbers of the selected k _r orthogonal vectors. The number of complex numbers that need to be fed back in each layer is reduced from (2L-1)M to 2L*k _r , achieving frequency domain compression.

Therefore, what the terminal needs to feedback is the quantized and/> The selected orthogonal basis vector matrix corresponding to the corresponding position/> index indication information.

Currently, the polarization difference method has been used for quantization in NR. The specific quantification method is as follows: in The largest amplitude coefficients are found in the first L rows and the last L rows of the matrix to form a polarization matrix. The L row where the strongest amplitude coefficient is located is called the strong polarization part, and the other half is called the weak polarization part. for/> The first L rows and the last L rows in the matrix are normalized according to the corresponding maximum amplitude coefficients. The polarization matrix is also normalized according to the largest amplitude coefficient in its own matrix. The strong polarization coefficient in the polarization matrix is normalized to 1. There is no need to perform amplitude and phase quantization. The terminal informs the network equipment through the strongest coefficient indication information. Weak amplitude polarization coefficients need to be quantized. For polarization normalized/> Matrix (For{c _l,k ,(l,k)≠(l ^* ,k ^* )}), both amplitude and phase need to be quantized.

After codebook compression, the following parameters exist:

K0: The number of subset coefficients, configured by the network device, is used to indicate the multi-layer compression coefficient matrix How many coefficients need feedback, i.e. for/> Coefficients other than K0 coefficients in the matrix are considered to be 0 and there is no feedback. For rank1/2, K0 coefficients are selected independently between layers. For rank3/4, all layers jointly select 2*K0 coefficients, that is, for rank 1, only K0 coefficients need to be quantized. For rank>1, all layers need to quantize a total of 2*K0 coefficients.

Number Of Non-Zero Coefficients Indication (NNZCI), for multi-layer compression coefficient matrices The sum of all non-zero coefficients is K1, and the total number of subset coefficients is K0 or 2*K0. If K1 is less than the total number of subset coefficients, the terminal only needs to feed back K1 coefficients. Therefore, part 1 needs to feedback the indication information of the non-zero coefficient.

Bitmap: bitmap is a matrix with X rows and Xi columns. The rows are related to the number of SD beams, and the columns are related to the number of orthogonal fundamental beams, where i represents the layer. For each layer, there is an independent bitmap used to indicate the position of the non-zero coefficients of the current layer and the number of non-zero coefficients of the current layer.

When type 2 CSI reports are transmitted on PUSCH, since the network equipment cannot know the CSI feedback, especially the payload size of part 2, in advance, the allocated PUSCH resources may not be able to accommodate the complete CSI report content, so the terminal needs to discard part 2 of the CSI. Some content will not be fed back. Assuming that N CSI reports need to be fed back in one time slot, the priority of part2 content discarding of CSI (Priority) is shown in Table 1: Priority 0 is the highest priority, that is, the CSI report content is sent first; priority 2N is the lowest The priority is the CSI report content that is discarded first. When discarding, the entire CSI report content of each priority level is discarded.

Table 1: Part 2 CSI report priority

When the UE is scheduled to transmit uplink data (transport block) and one or more CSI reports on PUSCH, if Greater than/> Then part 2 of CSI is discarded step by step in the above order until/> Less than or equal to/> until. in:

O _CSI-2 is the number of bits of CSI part 2;

If O _CSI-2 ≥ 360, L _CSI-2 = 11; otherwise L _CSI-2 is the number of cyclic redundancy check (CRC) bits of CSI part 2 determined according to preset rules;

is the set CSI offset value;

is the total number of OFDM symbols in PUSCH, including all OFDM symbols that transmit DMRS;

is the number of REs used to transmit UCI on OFDM symbol l in PUSCH;

C _UL-SCH is the number of code blocks of UL-SCH transmitted on PUSCH;

If the DCI scheduling the PUSCH contains a code block group transmission information (CBGTI) field to instruct the UE not to send the r-th code block, K _r = 0; otherwise K _r is the r-th code block size of the UL-SCH transmitted on the PUSCH ;

Q' _CSI-1 is the number of coded modulation symbols for each layer of CSI part 1 transmitted on PUSCH;

If the number of HARQ-ACK information bits is greater than 2, Q' _ACK is the number of encoded modulation symbols for each layer transmitted on PUSCH. If the number of HARQ-ACK information bits is equal to 1 or 2, Q' _ACK = 0;

α is the proportion parameter of high-level configuration;

When the UE only transmits the CSI report on the PUSCH, part 2 of the CSI is discarded step by step in the above order until the code rate of part 2 CSI is lower than a threshold code rate c _T less than 1, where

is the set CSI offset value, and R is the code rate indicated by DCI.

When transmitting type 2 CSI on the PUCCH, part 2 CSI is still discarded according to the priority in Table 1, starting from the lowest priority until the code rate of part 2 CSI is less than or equal to the parameter maxCodeRate configured by the higher layer.

The existing type 2 CSI discarding scheme is to directly discard the subband CSI information, which is used to ensure that the CSI report can be placed in the uplink resources configured by the corresponding network device. However, for the codebook based on Fourier transform compression in New Radio (NR), the information put into the CSI report no longer has the concept of subbands. Therefore, the existing discarding scheme cannot be used, so the network equipment After receiving the CSI report, it is impossible to determine the part of the CSI discarded by the terminal. In this way, the network device will not be able to accurately judge the channel condition based on the CSI report, resulting in deterioration of CSI feedback performance.

In order to solve the above problems, embodiments of the present invention provide a transmission method of channel state information CSI report, a terminal and a network device to solve the problem that the network device cannot accurately determine the channel condition due to the inability to determine the part of the CSI discarded by the terminal. question.
