2. Channel Matrix

1. Channel model

In a Multiple Input Multiple Output (MIMO) system, the transmitter has a antennas and the receiver has b antennas. The channel model of the MIMO channel can be expressed as:

r＝Hs+n ₀ ;

Among them, r is the received signal vector after passing through the MIMO channel; s is the transmitted signal vector at the transmitter; H is the b×a order channel matrix for the MIMO channel; n ₀ is the additive noise vector.

In the precoding mode, the transmitter can use the precoding mode to optimize the spatial characteristics of the transmitted signal vector s according to the channel matrix H, so that the spatial distribution characteristics of the transmitted signal vector s match the channel matrix H, thereby effectively reducing Dependence on the receiver algorithm and simplify the receiver algorithm. Through precoding, system performance can be effectively improved.

Precoding can use linear or nonlinear methods. Due to complexity and other reasons, only linear precoding is generally considered in current wireless communication systems. After precoding, the channel model of the MIMO signal can be expressed as:

r＝HWs+n ₀ ;

Among them, W is the precoding matrix.

For MU-MIMO, the receiver cannot perform channel estimation on signals sent to other devices, so transmitter precoding can effectively suppress multi-user interference. It can be seen that it is beneficial to the system that the transmitter knows the channel matrix and uses appropriate precoding to process it.

In addition, in the precoding method, the precoding matrix W and the channel matrix H jointly determine the equivalent channel matrix (such as HW), and the equivalent channel matrix determines the channel characteristics/characteristics, etc. In addition, in some cases, the precoding matrix W can be derived from the channel matrix H. For example, the precoding matrix W can be a matrix under a certain transformation of the channel matrix H.

2. Singular Value Decomposition (SVD) of the channel matrix H

The singular value decomposition of the channel matrix H can be:

H＝U∑V ^T ;

Among them, U=[u ₁ ,u ₂ ,…, _ub ] is an orthogonal matrix or unitary matrix of order b×b, that is, it satisfies U ^T U=I;

V=[v ₁ , v ₂ ,..., _va ] is an orthogonal matrix or chief matrix of order a×a, that is, it satisfies V ^T V=I. The column vectors in V can be called right-singular vectors of the channel matrix H;

∑ is a diagonal matrix of order a×a. The elements on the diagonal are p=min(b,a) singular values σ ₁ , σ ₂ ,..., σ _p of the channel matrix H, which are reduced in descending order The order of σ ₁ >σ ₂ >...>σ _p .

3. Processing of channel matrix H

Perform matrix multiplication on the conjugate transpose H ^T of the channel matrix and the channel matrix H to obtain a square matrix H ^T H of order a×a. By performing eigendecomposition on the square matrix H ^T H, the obtained eigenvalues and eigenvectors exist as follows:

(H ^T H)v _i =λ _i v _i ,i∈[1,a];

Among them, λ _i represents the eigenvalue of the square matrix H ^T H; _vi represents the eigenvector of the square matrix H ^T H.

It can be obtained from H=U∑V ^T , (H ^T H)=V∑ ² V ^T .

Therefore, the eigenvectors of H ^T H also represent the column vectors in V above. That is to say, all the eigenvectors of H ^T H can form the above V, and the eigenvectors of the square matrix H ^T H can be the right singular vector of the channel matrix H.

4. Obtaining the channel matrix H

In this embodiment of the present application, the terminal equipment performs channel measurement/evaluation/detection/estimation through downlink reference signals to obtain the channel matrix H. Among them, the downlink reference signal may include channel state information reference signal (Channel State Information Reference Signal, CSI-RS), synchronization information block (SSB) or physical broadcast channel demodulation reference signal (PBCH DMRS).

For example, the terminal device can perform downlink channel evaluation/detection/estimation/measurement on the current channel according to the CSI-RS to obtain the channel matrix, thereby obtaining the channel matrix through the CSI-RS.

For another example, the terminal device can perform downlink channel measurement/evaluation/detection/estimation on the current channel according to SSB or PBCH DMRS to obtain the channel matrix, thereby obtaining the channel matrix through SSB or PBCH DMRS.

3. CSI reporting process

1. CSI configuration

The protocol standards developed by 3GPP have conducted relevant research on CSI.

CSI can be channel state information used by the terminal device to feed back the downlink channel quality to the network device. That is, the terminal device can feed back the downlink channel quality to the network device based on CSI, so that the network device can select an appropriate modulation and coding strategy for the transmission of downlink data. (Modulation and Coding Scheme, MCS), reduce the block error rate (Block Error Rate, BLER) of downlink data transmission, and perform corresponding beam management, mobility management, adaptation tracking, rate matching and other processing.

The relevant configuration information for CSI can be defined by the high-level parameter CSI-MeasConfig. Among them, CSI-MeasConfig can indicate or include the following two high-level parameters: CSI resource configuration information (CSI-ResourceConfig) and CSI report configuration information (CSI-ReportConfig).

In addition, since CSI-ReportConfig will indicate or contain CSI-ResourceConfigId, CSI-ResourceConfig will be associated (corresponding/mapping) to CSI-ReportConfig through CSI-ResourceConfigId.

CSI-ReportConfig is used to configure CSI reporting, that is, configure CSI reporting.

CSI-ResourceConfig is used to configure CSI-RS resources for CSI measurement. In addition, CSI-ResourceConfig can configure a resource set (such as ResourceSet), and the ResourceSet can include the most basic CSI-RS resources (such as CSI-RS-Resource).

CSI-RS-Resource may indicate or include NZP-CSI-RS resource set (NZP-CSI-RS-ResourceSet), CSI Interference Measurement (CSI-IM) resource set (CSI-IM-ResourceSet), SSB resource There are three types of sets (CSI-SSB-ResourceSet).

NZP-CSI-RS-ResourceSet can be used for channel measurement and/or interference measurement; CSI-IM-ResourceSet can be used for interference measurement; CSI-SSB-ResourceSet can be used for channel measurement.

The type of CSI-RS resources can be periodic, semi-persistent or aperiodic.

The report configuration type (reportConfigType) in CSI-ReportConfig can be used to indicate the report type of the CSI report. Among them, the CSI report can be transmitted through the physical uplink control channel (physical uplink control channel, PUCCH) or the physical uplink shared channel (physical uplink shared channel, PUSCH).

2. CSI report

(1) Report type of CSI report

Report types of CSI reports may include: periodic (periodic) CSI reports, aperiodic (aperiodic) CSI reports, semi-persistent (semi-persistent on PUCCH) CSI reports, and semi-persistent CSI reports carried on PUSCH.

It should be noted that since the PUCCH needs to be used to report periodic CSI, the periodic CSI report is carried by the PUCCH. Since PUSCH needs to be used to report aperiodic CSI, aperiodic CSI reports are carried by PUSCH.

For aperiodic CSI reports and semi-persistent CSI reports carried on PUSCH, network equipment will also configure the high-level parameter TriggerState and the high-level parameter reportTriggerSize to cooperate with the CSI request field (CSI request field) in DCI (downlink control information, DCI).

◆Periodic CSI report

After configuring periodic CSI-RS Resource and Report parameters through RRC messages (or RRC signaling), they will take effect immediately without the need to activate or trigger CSI-RS transmission and CSI reporting through MAC-CE/DCI.

◆Semi-persistent CSI report carried on PUCCH

If you configure semi-persistent CSI-RS transmission through RRC messages, you need to activate CSI-RS transmission through MAC CE1 first, and then activate CSI reporting through MAC CE2; if you configure periodic CSI-RS transmission through RRC messages, you do not need to activate CSI-RS transmission through MAC CE1 Activate CSI-RS transmission and only activate CSI reporting through MAC CE2.

◆Semi-persistent CSI report carried on PUSCH

If you configure semi-persistent CSI-RS transmission through RRC messages, you need to activate CSI-RS transmission through MAC CE1 first, and then trigger CSI reporting through DCI; if you configure periodic CSI-RS transmission through RRC messages, you do not need to activate CSI through MAC CE1 -RS is sent while only triggering CSI reporting via DCI.

It should be noted that for DCI, the DCI can be DCI format (format) 0_1 scrambled using SP-CSI-RNTI (semi-persistent CSI RNTI), and the CSI request field in the DCI can pass the code point (codepoint) The settings are associated with the corresponding trigger state (TriggerState). The associated CSI-ReportConfig will be defined in the TriggerState, so that the CSI-ReportConfig associated with the PUSCH upper half-persistent CSI report can be found through the TriggerState.

◆Aperiodic CSI report

For the scenario of aperiodic CSI-RS transmission and aperiodic CSI reporting, aperiodic CSI-RS transmission and aperiodic CSI reporting are both triggered by DCI, and the process is similar to the above-mentioned semi-persistent CSI reporting.

When the corresponding TriggerState is associated with the codepoint of the CSI request field in DCI format 0_1/0_2, it is different from the DCI trigger in the above-mentioned semi-persistent CSI report. If the value of the CSI request field is 0, it means that the trigger half cycle is not required. CSI report; if the value of the CSI request field is 1, then the table Indicates that the aperiodic CSI report associated with TriggerState 1 is triggered, and so on.

(2) Type of information contained in the CSI report

The CSI report may contain at least one of the following information: layer 1 reference signal received power (L1-RSRP), layer 1 signal-to-noise and interference ratio (L1) -SINR), CSI-related information, etc.

Specifically, CSI-related information may include at least one of the following information: CSI-RS Resource Indicator (CRI), Synchronization Signal Block Resource Indicator (SS/PBCH block resource indicator) , SSBRI), rank indicator index (rank indicator, RI), precoding matrix indicator index (precoding matrix indicator, PMI), channel quality indicator index (channel quality indicator, CQI), layer indicator index (layer indicator, LI), etc.

It should be noted that the CRI (or SSBRI) may represent the CSI-RS (or SSB) resources recommended (or selected) by the terminal device. Among them, a CSI-RS (or SSB) resource can represent a beam or antenna direction.

RI can represent the number of layers recommended (or selected) by the terminal device, and the number of layers can determine which codebook. Among them, each layer corresponds to a codebook, and a codebook consists of one or more codewords. For example, a codebook with a level of 2 or a codebook with a level of 1.

PMI can represent the index of the codeword in the codebook recommended (or selected) by the terminal device, or the quantized precoding information. Among them, one codeword corresponds to one precoding matrix. RI and PMI can collectively represent the number of layers and precoding matrix recommended by the terminal device.

CQI can indicate the channel quality of the current channel that the terminal device feeds back to the network device. Among them, the terminal device needs to calculate CQI.

(3)CSI report on PUSCH

The standard protocols specified by 3GPP (such as NR R15/16/17) support Type I (Type I) CSI feedback (feedback), Type II CSI feedback, Enhanced (Enhanced) Type II CSI feedback, and Further Enhanced (Further Enhanced) Type II CSI feedback.

The basic principle of Type I CSI feedback is that the terminal device can match the codebook specified by the protocol with the estimated channel, select the codebook that best matches the channel, and then feed back the index corresponding to the codebook to the network device.

The basic principle of Type II CSI feedback, enhanced Type II CSI feedback and further enhanced Type II CSI feedback is: use high-resolution CSI feedback to perform certain processing on the estimated channel, thereby feeding back the processed information, including amplitude and Phase quantization, etc.

The CSI report on PUSCH supports Type I CSI feedback, Type II CSI feedback, enhanced Type II CSI feedback, and further enhanced Type II CSI feedback.

For Type I CSI feedback, Type II CSI feedback, enhanced Type II CSI feedback and further enhanced Type II CSI feedback on PUSCH, a CSI report can be composed of two parts (part), namely Part 1 (Part 1) and Part 2 (Part 2).

The payload size of Part 1 is fixed, and Part 1 can be used to determine the number of information bits in Part 2.

Additionally, Part 1 and Part 2 may contain different content under different circumstances. details as follows:

◆For Type I CSI feedback: Part 1 can include RI (if reported), CRI (if reported), CQI of the first codeword (if reported); Part 2 can include PMI (if reported) reported), CQI (if reported) of the second codeword when RI (if reported) is greater than 4, LI (if reported).

◆For Type II CSI feedback: Part 1 may contain an indication of the RI (if reported), CQI, and the number of non-zero wideband amplitude coefficients for each layer of Type II CSI. Among them, the fields of Part 1 (RI, CQI, indication of the number of non-zero wideband amplitude coefficients per layer) are coded separately. Part 2 may contain Type II CSI PMI, LI (if reported). Among them, part 1 and part 2 are encoded separately.

◆For enhanced Type II CSI feedback: Part 1 can contain RI (if reported), CQI, all layers of enhanced Type II CSI) non-zero amplitude An indication of the total number of coefficients. Among them, the fields of part 1 (RI, CQI, indication of the total number of non-zero amplitude coefficients) are coded separately. Part 2 may include PMI that enhances Type II CSI. Part 1 and part 2 may be encoded separately.

It should be noted that the relevant content/concepts/definitions/explanations, etc. in "(3) CSI report on PUSCH" can be found in the corresponding chapters in the standard protocol 38.214, and there are no specific restrictions on this. In addition, the relevant content/concepts/definitions/explanations, etc. in "(3) CSI Report on PUSCH" may also be adapted to the modifications/changes of the standard protocol 38.214. Those skilled in the art can also deduce/obtain the modified content by combining the relevant content/concepts/definitions/explanations, etc. in "(3) CSI Report on PUSCH". Therefore, the modified content is also within the scope of protection claimed by this application and will not be described again.

(4)Priority of CSI report

A CSI report is associated with a priority value Pri _CSI (y,k,c,s):

Pri _CSI (y,k,c,s)=2·N _cells ·M _s ·y+N _cells ·M _s ·k+M _s ·c+s; where,

-For aperiodic CSI reports scheduled to be carried on PUSCH, the value of y can be 0; for semi-persistent CSI reports scheduled to be carried on PUSCH, the value of y can be 1; for scheduled CSI reports carried on PUCCH For semi-persistent CSI reports, the value of y can be 2; for periodic CSI reports scheduled to be carried on the PUCCH, the value of y can be 3; and so on.

The value of -k may be determined by the type of information contained in the CSI report indicated by the information in CSI-ReportConfig (such as reportQuantity).

For example, for a CSI report that contains (carrying/carrying) L1-RSRP or L1-SINR, the value of k can be 0; for a CSI report that does not contain (carrying/bearing) L1-RSRP or L1-SINR, the value of k can be Value can be 1; etc.

The value of -c can be the serving cell index value.

The value of -s can be the value of reportConfigID in CSI-ReportConfig.

The value of -N _cells can be the value of the high-level parameter maxNrofServingCells.

The value of -M _s can be the value of the high-level parameter maxNrofCSI-ReportConfigurations.

It should be noted that the name of the maximum number of serving cells specified in the 5G standard is maxNrofServingCells, the name of the configuration index of the CSI report is reportConfigID, and the name of the maximum number of configurations of the CSI report is maxNrofCSIReportConfigurations, but other standards specify names with the same meaning. The same applies to this application, that is, this application does not limit the names of these parameters.

Since a CSI report is associated with a priority value, if the priority value Pri _CSI (y,k,c,s) associated with one CSI report is less than the priority value Pri _CSI (y,k) associated with another CSI report ,c,s), then the priority of this CSI report is higher than the priority of the other CSI report.

If two CSI reports are transmitted on the same carrier and at least one OFDM symbol overlaps with each other in the time domain, the two CSI reports collide during transmission.

When an end device is configured to transmit two conflicting CSI reports,

- If the values of y are different between the two CSI reports, and except in the case where one of the y has a value of 2 and the other of y has a value of 3, the following rules apply:

◆The terminal device does not transmit CSI reports with a higher priority value Pri _CSI (y,k,c,s);

- Otherwise, the two CSI reports can be multiplexed or discarded based on the priority value.

It should be noted that the relevant content/concepts/definitions/explanations, etc. in the above "(4) CSI report priority" can be found in the corresponding chapters of the standard protocol 38.214, and there are no specific restrictions on this. In addition, the relevant content/concepts/definitions/explanations, etc. in "(4) Priority of CSI Reports" may also be modified to adapt to the modifications/changes of the standard protocol 38.214. Those skilled in the art can also deduce/obtain the modified content by combining the relevant content/concepts/definitions/explanations, etc. in "(4) Priority of CSI Reports". Therefore, the modified content is also within the scope of protection claimed by this application and will not be described again.

(5) CSI processing unit (CPU) occupied by CSI report

①Meaning

In a component carrier (Component Carrier, CC), the terminal device can indicate the number of simultaneous CSI calculations (simultaneous CSI calculations) it supports through the high-level parameter simultaneousCSI-ReportsPerCC, N _CPU ; in all component carriers, the terminal device can use the high-level parameter to indicate the number of simultaneous CSI calculations (N CPU) it supports. The parameter simultaneousCSI-ReportsAllCC indicates the number of simultaneous CSI calculations supported by itself, N _CPU .

If the terminal device supports simultaneous CSI calculation, the terminal device is said to have N _CPUs for processing CSI reports.

It should be noted that the CPU occupied by the CSI report can represent the terminal device's ability to process CSI. N _CPU can be understood as the maximum number or total number of CPUs supported by the terminal device. In addition, the N _CPU can be reported by the terminal device to the network device through high-level parameters (such as simultaneousCSI-ReportsPerCC and/or simultaneousCSI-ReportsAllCC).

If the calculation of CSI in a given OFDM symbol has occupied L CPUs, the terminal device has N _CPUs - L unoccupied CPUs.

Among N _CPU -L unoccupied CPUs, if N CSI reports occupy their respective CPUs sequentially on the same OFDM symbol, and the CPU occupied by the n (n=0,...,N-1)th CSI report The quantity is Then the terminal device does not need to update (update) NM ₁ CSI report with low priority, M ₁ (0≤M ₁ ≤N) is used established maximum value.

For example, the network device configures three CSI reports for the terminal device, namely CSI report 0, CSI report 1 and CSI report 2. Among the corresponding priorities of the three CSI reports, the priority of CSI report 0 is higher than the priority of CSI report 1, and the priority of CSI report 1 is higher than the priority of CSI report 2. In the case where the terminal device has 10 unoccupied CPUs, if the CSI report 0 occupies 5 CPUs (i.e. ), CSI report 1 occupies 3 CPUs (i.e. ), CSI report 2 occupies 5 CPUs (i.e. ), then since 5+3+5>10, the terminal device does not need to update CSI report 2.

②Amount of CPU occupied by one CSI report

The number of CPUs occupied by a CSI report is O _CPU and can exist as follows:

◆If the high-level parameter reportQuantity in CSI-ReportConfig is set to 'none', and the high-level parameter trs-Info is configured in CSI-RS-ResourceSet, then O _CPU = 0. In other words, the number of CPUs occupied by the CSI report is 0.

◆If the high-level parameter reportQuantity in CSI-ReportConfig is set to 'cri-RSRP', 'ssb-Index-RSRP', 'cri-SINR', 'ssb-Index-SINR' or 'none' (at this time CSI-RS- ResourceSet is not configured with the high-level parameter trs-Info), then U _CPU = 1. In other words, the number of CPUs occupied by the CSI report is 1.

◆If the high-level parameter reportQuantity in CSI-ReportConfig is set to 'cri-RI-PMI-CQI', 'cri-RI-i1', 'cri-RI-i1-CQI', 'cri-RI-CQI' or 'cri -RI-LI-PMI-CQI', then:

- If max(μ _PDCCH ,μ _CSI-RS ,μ _UL )<3, a CSI report is triggered aperiodic, L=0 CPUs are occupied, and the terminal device does not send a transmission block (or HARQ-ACK or both ), and the CSI corresponds to a single CSI with wideband frequency granularity and corresponds to up to 4 CSI-RS ports in a single resource with codebookType set to 'typeI-SinglePanel' or reportQuantity set to 'cri-RI- CQI', then O _CPU = N _CPU . In other words, the number of CPUs occupied by CSI reporting is the total number of CPUs reported by the terminal equipment. Among them, μ _PDCCH corresponds to the subcarrier spacing of the PDCCH that transmits DCI, and μ _UL corresponds to the bearer The subcarrier spacing of the PUSCH of CSI, μ _CSI-RS corresponds to the subcarrier spacing of the aperiodic CSI-RS triggered by DCI.

- If the codebookType in the CSI-ReportConfig corresponding to a CSI report is set to 'typeI-SinglePanel', and the corresponding CSI-RS resource set used for channel measurement is configured with 2 resource groups, including N resource pairs, M For resources under the assumption of single-site transmission, O _CPU =2N+M. In other words, the number of CPUs occupied by the CSI report is 2N+M.

- Otherwise, O _CPU = K _s , K _s is the NZP-CSI-RS resource used for channel measurement in the NZP-CSI-RS-ResourceSet (also called is the number of channel measurement resources). That is to say, the number of CPUs occupied by the CSI report is the number of channel measurement resources associated with the CSI report.

③The number of OFDM symbols occupied by the CPU

●For CSI reports where the high-level parameter reportQuantity in CSI-ReportConfig is not set to ‘none’, the number of OFDM symbols occupied by the CPU occupied by the CSI report can exist as follows:

-The OFDM symbols occupied by the CPU occupied by periodic CSI reporting or semi-persistent CSI reporting (excluding the first (initial) semi-persistent CSI report on PUSCH after the PDCCH triggering report) are:

Starting from the first symbol of the earliest CSI-RS/CSI-IM/SSB resource used for channel measurement or interference measurement, and the respective latest CSI-RS/CSI-IM/SSB timing is no later than The corresponding CSI reference resource is up to the last symbol of the reported resource, where the reported resource is the PUSCH/PUCCH used to carry the periodic CSI report or semi-persistent CSI report.

Starting from the first symbol after the PDCCH to the last symbol of the reported resource, where the reported resource is the PUSCH used to carry the first semi-persistent CSI report.

●For CSI reports where the high-level parameter reportQuantity in CSI-ReportConfig is set to ‘none’ and the CSI-RS-ResourceSet is not configured with the high-level parameter trs-Info, the number of OFDM symbols occupied by the CPU occupied by the CSI report can exist as follows:

-The OFDM symbols occupied by the CPU occupied by the semi-persistent CSI report (excluding the first (initial) semi-persistent CSI report on the PUSCH after the report is triggered by the PDCCH) are:

Starting from the first symbol of the earliest one of each transmission occasion (transmission occasion) of the periodic or semi-persistent CSI-RS/SSB resources used for L1-RSRP calculation, until Z′ ₃ symbols after the last symbol of the latest one in the CSI-RS/SSB resources used for channel measurement for L1-RSRP calculation.

-The OFDM symbols occupied by the CPU occupied by the aperiodic CSI report are:

From the first symbol after the PDCCH that triggers the CSI report to the last symbol between Z ₃ symbols after the first symbol after the PDCCH that triggers the CSI report and Z′ ₃ symbols after the measurement resource; where , the measurement resource is the latest one among the CSI-RS/SSB resources used for channel measurement in L1-RSRP calculation.

It should be noted that the relevant content/concepts/definitions/explanations, etc. in the above "(5) CPU occupied by CSI report" can be found in the corresponding chapters of the standard protocol 38.214, and there are no specific restrictions on this. In addition, the relevant content/concepts/definitions/explanations, etc. in "(5) CPU occupied by CSI report" may also be modified to adapt to the modification/change of the standard protocol 38.214. Those skilled in the art can also deduce/obtain the modified content by combining the relevant content/concepts/definitions/explanations, etc. in "(5) CPU occupied by CSI report". Therefore, the modified content is also within the scope of protection claimed by this application and will not be described again.

It should be noted that the relevant content/concepts/definitions/explanations, etc. in the above "(6) CSI calculation time requirements for CSI reports" can be found in the corresponding chapters of the standard protocol 38.214, and there are no specific restrictions on this. In addition, the relevant content/concepts/definitions/explanations, etc. in "(6) CSI calculation time requirements for CSI reports" may also be adapted to the modifications/changes of standard protocol 38.214.

Therefore, the modified content is also within the scope of protection claimed by this application and will not be described again.

4. Introducing compression processing into the CSI calculation process

As a possible application scenario, this application can introduce compression processing in the process of CSI calculation, that is, CSI feedback that supports compression processing.

It should be noted that this application can adopt various methods to introduce compression processing in the process of CSI calculation.

For example, this application uses AI algorithms to introduce compression processing into the CSI calculation process in order to improve the corresponding accuracy, etc. This is because AI algorithms can establish solutions to some complex problems through training with large amounts of data, and have the ability to process large amounts of complex information and with high processing accuracy. They can effectively solve some problems that are difficult to solve using traditional modeling methods, such as Some nonlinear problems, parameters are too complex and other problems. Among them, AI algorithms can include machine learning (ML), deep learning (DL), etc.

Combined with the content in "3. CSI Reporting Process" above, since the channel information obtained by the terminal device through channel measurement may have characteristics such as a large number of bits, feedback of the channel information directly through the CSI report will result in occupied resources. There are many problems, such as large signaling overhead, etc. Therefore, the method of not directly feeding back the channel information is usually used. Instead, the channel information needs to be processed accordingly to obtain CSI related information (such as RI, PMI, etc.), and then the CSI related information is fed back. That is, codebook-based CSI feedback.

However, when compression processing is introduced in the process of CSI calculation, the terminal device in the embodiment of the present application can compress the channel information through a compression processing module (such as an AI module), and feed back the compressed channel information ( or reported). Compared with codebook-based CSI feedback, the compressed channel information has the characteristics of smaller number of bits and higher accuracy, which results in less resources occupied, less signaling overhead, and higher accuracy.

In addition, in some scenarios, compared with codebook-based CSI feedback, the compressed channel information may have more information (that is, the compressed channel information has higher accuracy), such as amplitude information.

In the above "3. CSI report process", the embodiment of the present application introduces the information types and information contained in the CSI report without introducing compression processing. CSI report on PUSCH, priority of CSI report, CPU occupied by CSI report, CSI calculation time requirement of CPU report, etc.

In combination with the above content, the following embodiments of the present application will specifically introduce the information type contained in the CSI report, the CSI report on the PUSCH, the priority of the CSI report, the CPU occupied by the CSI report, and the CSI reported by the CPU when compression processing is introduced. Calculation time requirements, and other related content.

1. Channel information, compression information, configuration information, first CSI report and second CSI report

(1)Channel information

It should be noted that channel information can characterize channel characteristics/characteristics.

Combined with the content in "2. Channel Matrix" above, the channel information in the embodiment of the present application may include at least one of the following: channel matrix H, equivalent channel matrix, and precoding matrix W (precoding matrix W can be derived from the channel matrix H out), the right singular vector V of the channel matrix H, the eigenvector v _i of the square matrix H ^T H (the eigenvector of the matrix obtained by multiplying the conjugate transpose H ^T of the channel matrix H by the channel matrix H), the channel matrix H correlation vector (such as the vector of the channel matrix H under certain deformation, etc.).

In addition, in some possible implementations, the channel information may also include time domain information of the channel, channel information in the delay-doppler domain, etc., which are not specifically limited.

Combined with the content in "4. Acquisition of Channel Matrix H" above, in some possible implementations, channel information can be obtained by channel measurement/evaluation/detection/estimation through downlink reference signals.

(2) Compressed information

Since the channel information may have characteristics such as a large number of bits, directly feeding back the channel information will lead to problems such as occupying more resources and high signaling overhead. Therefore, the method of not directly feeding back the channel information is usually adopted. In order to reduce occupied resources, signaling overhead, etc., embodiments of the present application adopt a method of compressing channel information, so that the compressed channel information (ie, compressed information) has characteristics such as a smaller number of bits.

In this embodiment of the present application, the compressed information may be information after the channel information has been compressed. The compression processing of channel information may include at least one of compression, quantization, coding, etc.

In some possible implementations, the terminal device in the embodiment of the present application can use the compression processing module to compress the channel information. The compressed channel information has the characteristics of smaller number of bits, higher precision, etc., so that the occupied resources Less, less signaling overhead, higher accuracy, etc.

In addition, the compression processing module may be a software unit and/or a hardware unit that uses AI models/AI algorithms (such as convolutional neural network algorithms, deep neural network algorithms, etc.) to perform information processing.

For example, the terminal device can input channel information into the AI module to obtain compressed information. That is, the compressed information is the information after the channel information has been compressed by the AI module, thereby utilizing the AI module's ability to process large amounts of complex information/data and its ability to process high accuracy to achieve compression of channel information and ensure the accuracy of the compressed information. .

Therefore, in the embodiment of this application, "compressed information" can be regarded as information after compression processing. "Channel information" can be regarded as the information before compression processing. Taking the AI module to compress channel information as an example, the compressed information can be understood as the output information of the AI module; the channel information can be understood as the input information of the AI module.

Of course, in this embodiment of the present application, the terminal device can also compress and process the channel information through other methods to obtain compressed information.

For example, the other method may be a lossy compression method, a lossless compression method, etc. Among them, lossy compression is mainly some quantization algorithms, such as a rate, u rate, Lloyds and other optimal quantization. Lossless compression mainly involves some coding algorithms, such as subband coding, differential coding, Huffman coding, etc.

In some possible implementations, the terminal device can perform channel measurement through the downlink reference signal to obtain channel information, compress the channel information to obtain compressed information, and report the compressed information to the network device through a CSI report. Correspondingly, the network device can perform corresponding decompression processing on the compressed information to obtain channel information.

For example, taking the AI module for compression processing as an example, the terminal device performs channel measurement through CSI-RS to obtain channel information, inputs the channel information into the AI module for compression to obtain the compressed information, and then sends it to the network device through PUSCH or PUCCH. Correspondingly, the network device inputs the compressed information to the AI module and decompresses it to obtain the channel information. For another example, taking the AI module for compression processing as an example, the terminal device performs channel measurement through CSI-RS to obtain channel information, inputs the channel information into the AI module for compression, and then undergoes quantization, coding, etc. to obtain the compressed information. Finally, through PUSCH or PUCCH is sent to the network device. Correspondingly, the network device performs corresponding decoding, dequantization and other processing on the compressed information, and then inputs it to the AI module for decompression to obtain channel information.

(3)Configuration information

①Definition

In this embodiment of the present application, the network device can determine the CSI report containing (carrying) compression information through configuration information, thereby informing (notifying/instructing/requiring, etc.) the terminal device that the CSI report should contain compression information through network configuration.

For example, the configuration information may be used to determine a CSI report containing compression information. Alternatively, the configuration information may be used to indicate that the CSI report contains compression information. Alternatively, the configuration information is used to indicate the type of information included in the CSI report. For example, the information types contained in the CSI report include information type 1 and information type 2. The CSI report of information type 1 includes compressed information, and the CSI report of information type 2 does not include compressed information. In this case, the configuration information is used to indicate Information type 1 indicates that the configuration information indicates that the CSI report includes compression information. Of course, the embodiments of the present application may also use other methods to describe the configuration information used to determine the CSI report including compression information, which is not limited.

Of course, the configuration information can also be described using other terms, such as indication information, first information, etc., as long as they have the same meaning/function/interpretation/concept, etc., they are all within the scope of protection claimed by the embodiments of this application, and no specific details will be given on this. limit.

In some possible implementations, the configuration information can also be used to configure CSI reports and/or CSI resources.

For example, combined with the content in "1. CSI Configuration" above, the configuration information may include CSI-MeasConfig, CSI-ReportConfig or CSI-ResourceConfig. Among them, CSI-ReportConfig can be associated (corresponding/mapping, etc.) to CSI-ResourceConfig.

③Transmission of configuration information

In this embodiment of the present application, configuration information may be transmitted during cell search, cell reselection, uplink and downlink synchronization, cell access, cell camping, initial access, or uplink and downlink resource scheduling.

In some possible implementations, the configuration information may be carried by system information (SI), high-level signaling (such as RRC signaling), or terminal device-specific signaling.

④The type of information contained in the configuration information

●First instruction information

In some possible implementations, determining the CSI report containing (carrying) compression information through configuration information can be achieved in the following manner:

The configuration information may include first indication information, and the first indication information is used to indicate that the CSI report includes compression information. This enables the network device to indicate (configuration) to the terminal device that the CSI report needs to include compressed information during the CSI feedback process. In this regard, the terminal device needs to perform compression processing on the channel information to obtain the compressed information, and feedback the compressed information.

For example, the first indication information may be located in CSI-ReportConfig of the configuration information.

For example, the network device may indicate to the terminal device that the CSI report contains compression information through the first indication information in the CSI-ReportConfig.

Of course, the first indication information can also be described using other terms. As long as they have the same meaning/function/interpretation/concept, etc., they are within the scope of protection claimed by the embodiments of this application, and there is no specific limitation on this.

●First length information (optional)

In some possible implementations, the network device may indicate the length of the channel information to the terminal device through the first length information, so that the terminal device can obtain or use use. That is to say, the first length information can be used to indicate the length of the channel information.

This is because the channel information has a certain length (such as the length of the channel matrix (the length of the channel matrix can be determined by the dimensions of the channel matrix), the length of the vector associated with the channel matrix, etc.), so the network device configures the terminal device based on compression processing During the CSI feedback process, it is convenient for the terminal device to obtain or use it by indicating (configuring) the length of the signal information obtained by the terminal device.

For example, the network device may indicate the length of the channel information (or the length of the information before compression processing or the length of the input information of the AI module) to the terminal device through CSI-ReportConfig.

Of course, the first length information can also be described using other terms. As long as they have the same meaning/function/interpretation/concept, etc., they are within the scope of protection claimed by the embodiments of this application, and there is no specific limitation on this.

Generally, the length of the signal information indicated by the network device needs to comply with the reporting capability of the terminal device.

Therefore, in some possible implementations, the first length information may be determined by the terminal capability information reported by the terminal device. The terminal capability information may include the lengths of multiple channel information.

It can be understood that in the process of the terminal device reporting its own capabilities to the network device, the terminal device will report the lengths of multiple channel information. Then, the network device can select one length from the plurality of channel information, and then indicate it to the terminal device during the configuration process of the CSI report.

●Second length information (optional)

In some possible implementations, the network device may indicate the length of the compressed information to the terminal device through the second length information, so that the terminal device can obtain or use the compressed information. That is to say, the second length information can be used to indicate the length of the compressed information.

This is because the compressed information has a certain length. Therefore, when configuring CSI feedback based on compression processing to the terminal device, the network device can indicate (configure) the length of the compressed information required by the terminal device to facilitate the terminal device to obtain or use it. .

For example, the network device may indicate the length of the compressed information (or the length of the information after compression processing or the length of the output information of the AI module) to the terminal device through CSI-ReportConfig.

Of course, the second length information can also be described using other terms. As long as it has the same meaning/function/interpretation/concept, etc., it is within the scope of protection claimed by the embodiments of this application, and there is no specific limitation on this.

In addition, the length of the compressed information indicated by the network device needs to comply with the reporting capability of the terminal device.

Therefore, in some possible implementations, the second length information may be determined by the terminal capability information reported by the terminal device. The terminal capability information may include multiple lengths of compressed information.

It can be understood that in the process of the terminal device reporting its own capabilities to the network device, the terminal device will report the lengths of multiple compressed information. Then, the network device can select one of the lengths of the plurality of compressed information, and then indicate it to the terminal device during the process of configuring CSI feedback based on compression processing.

In addition, in some possible implementations, the standard protocol may specify the association (correspondence/mapping) relationship between the first length information and the second length information. The association relationship can be pre-configured, network configured or specified by the protocol. During specific implementation, the network device can only indicate (configure) the first length information (or the second length information), thereby configuring the first length information and the second length information at the same time through this association relationship, which is beneficial to reducing signaling overhead. wait.

Correspondingly, in the terminal capability information, embodiments of the present application can also establish an association (correspondence/mapping) relationship between the lengths of multiple channel information and the lengths of multiple compressed information. The association relationship can be pre-configured, network configured or specified by the protocol. During specific implementation, the terminal device can only report the lengths of multiple channel information (or the lengths of multiple compressed information), thereby simultaneously reporting the lengths of multiple channel information and the lengths of multiple compressed information through this association relationship, which is beneficial to Can reduce signaling overhead, etc.

●Receive antenna quantity information (optional)

In some possible implementations, when the terminal device reports its own capabilities to the network device, the terminal device can report the number of antennas to the network by receiving the antenna number information. The device reports the total number of receiving antennas it has so that network devices can learn or refer to it. That is to say, the receiving antenna number information can be used to indicate the number of receiving antennas required by the terminal device to obtain channel information.

Since the dimension of the channel matrix H in the channel information (such as b×a) is composed of the number of transmitting antennas of the network device (such as a) and the number of receiving antennas of the terminal device (such as a), the network device will indicate to the terminal device (Configuration) The number of receiving antennas that the terminal device needs to use when obtaining signal information (such as b). Usually, the number of receiving antennas indicated by the network device is less than or equal to the total number of receiving antennas reported by the terminal device.

For example, the terminal device reports to the network device that it has four receiving antennas. Then, the network device can indicate to the terminal device through CSI-ReportConfig that two receiving antennas need to be used to obtain channel information.

Of course, the information on the number of receiving antennas can also be described using other terms. As long as they have the same meaning/function/interpretation/concept, etc., they are within the scope of protection claimed by the embodiments of this application, and there is no specific limitation on this.

To sum up, the configuration information may include at least one of the following: first indication information, first length information, second length information, and receiving antenna number information.

(4) First CSI report and second CSI report

Since the embodiment of the present application needs to discuss the CSI report under CSI feedback based on compression processing, in order to facilitate the distinction, the embodiment of the present application refers to the CSI report under CSI feedback based on compression processing (that is, the CSI report based on compression processing) as The "first CSI report" and the CSI report under CSI feedback that is not based on compression processing are called "second CSI reports".

That is to say, the first CSI report is a CSI report containing compressed information, that is, the embodiment of this application mainly discusses the first CSI report in "4. Introducing compression processing in the process of CSI calculation".

The second CSI report is a CSI report that does not include compressed information. That is, the embodiment of this application mainly discusses the second CSI report in "3. Process of CSI reporting (CSI reporting)".

Consistent with the content in "(1) Report type of CSI report" above, CSI reports based on compression processing can include: periodic CSI reports, aperiodic CSI reports, semi-persistent CSI reports carried on PUCCH, and CSI reports carried on PUSCH. Semi-persistent CSI reporting, no further details on this.

3. Under CSI feedback based on compression processing, the type of information contained in the CSI report

①Compress information

Since the embodiment of the present application requires compression of channel information to obtain compressed information, during the CSI feedback process, in order to save signaling and resource overhead, the CSI report based on compression processing may only include compressed information.

At this time, the network device needs to process the compressed information through compression processing to obtain channel information, and then determine CSI related information (such as RI, PMI, etc.) through the channel information.

②Interference measurement result information (optional)

In some possible implementations, since the compressed information only involves relevant channel measurement results, in order to ensure that the network device can obtain the relevant interference measurement results, the CSI report based on compression processing may also include interference measurement result information. The interference measurement result information may be used to indicate the interference measurement result. For example, the interference measurement result information may include at least one of interference measurement result information based on CSI-IM (ie, CSI interference measurement signal/resource) and interference measurement result based on NZP-CSI-RS.

In some possible implementations, the interference measurement result may be obtained by the terminal device performing interference measurement through NZP-CSI-RS-ResourceSet and/or CSI-IM-ResourceSet.

That is to say, the second indication information can be used to indicate relevant characteristics of the compressed information.

Combined with the content in "④ Information type contained in configuration information" above, the network device may indicate (configure) the length of the compressed information and/or the length of the channel information required by the terminal device, or not.

In addition, in some implementations, the network device may indicate the length of multiple compressed information and/or the length of the channel information to the terminal device, and the terminal device may select one from them.

However, in some possible implementations, the terminal device may not perform processing as instructed by the network device, that is, the length of the channel information and/or the length of the compressed information obtained by the terminal device may be different from what the network device indicates, or the network device may No instructions were given. In this regard, the terminal device reports the relevant characteristics of the compressed information (related characteristics/related formats, etc.) to the network device, which helps the network device decompress the compressed information based on the relevant characteristics of the compressed information to ensure that the obtained channel information is more accurate.

Of course, the second indication information can also be described using other terms. As long as they have the same meaning/function/interpretation/concept, etc., they are within the scope of protection claimed by the embodiments of this application, and there is no specific limitation on this.

In addition, the relevant characteristics of the compressed information can represent the information characteristics of the compressed information before and after compression processing.

Of course, the relevant features of the compressed information can also be described using other terms. As long as they have the same meaning/function/interpretation/concept, etc., they are within the scope of protection claimed by the embodiments of this application, and there is no specific limitation on this.

For example, the relevant characteristics of the compressed information may include at least one of the following: the length of the channel information, the length of the compressed information, the location of the compressed information in the AI module, etc.

It should be noted that since the AI module can be composed of multiple layers (such as convolution layer, pooling layer, etc.), the position of the compressed information in the AI module can indicate which layer in the AI module outputs the compressed information.

To sum up, the CSI report based on compression processing may include at least one of the following information: compression information, interference measurement result information, L1-RSRP, L1-SINR, CSI related information, and second indication information.

4. CSI report on PUSCH under CSI feedback based on compression processing

(1) Part 1 and Part 2

Combined with the content in the above "(3) CSI report on PUSCH", a CSI report based on compression processing can be composed of two parts, namely part 1 and part 2.

In order to facilitate distinction and description, in the embodiment of the present application, "Part 1" may also be called "Part 1" and "Part 2" may be called "Part 2". Therefore, the payload size of the first part is fixed and the first part can be used to determine the number of information bits in the second part.

Since part 1 is of fixed size and part 2 has a variable size and depends on part 1, this application can be implemented as follows:

Put some important information in part 1, so that when part 2 is discarded, the terminal device can still report important information to the network device through part 1 Use it as a relevant reference to avoid the loss of important information;

Put some information that determines the size of part 2 in part 1, so that the network device can use this information to retrieve part 2 and avoid blindly checking part 2, thereby improving retrieval efficiency.

Combined with the content in the above "2. Types of information contained in CSI reports under CSI feedback based on compression processing", the contents of Part 1 and Part 2 are as follows:

- Part 1 may contain at least one of the following: compression information, interference measurement result information, SSBRI, CRI, RI, CQI, LI, second indication information.

- Part 2 may contain at least one of the following: compression information, interference measurement result information, PMI, LI, CQI of the second codeword (if reported) when RI (if reported) is greater than 4.

It should be noted that the content contained in Part 1 and Part 2 is different. For example, if part 1 contains compressed information, part 2 does not contain compressed information. That is, in some possible implementations, the compressed information may be located in Part 1 or Part 2. In this way, by putting the compressed information into part 1 or part 2, it is helpful to improve the flexibility of transmitting the compressed information.

In some possible implementations, the interference measurement information may be located in Part 1 or Part 2. In this way, by putting the interference measurement result information into part 1 or part 2, it is beneficial to improve the flexibility of transmitting compressed information.

In some possible implementations, the SSBRI may be located in Part 1. This is because, since SSBRI can be important information/information that determines the size of part 2/information with a fixed size, SSBRI is located in part 1, which is beneficial to avoid the loss of important information, or avoid blind checking of part 2.

In some possible implementations, the CRI may be located in Part 1. This is because, since the CRI can be important information/information that determines the size of part 2/information with a fixed size, the CRI is located in part 1, which is beneficial to avoid the loss of important information, or avoid blind inspection of part 2.

In some possible implementations, the RI may be located in Part 1. This is because, since the RI can be important information/information that determines the size of part 2/information with a fixed size, the RI is located in part 1, which is beneficial to avoiding the loss of important information or blindly checking part 2.

In some possible implementations, the CQI may be located in Part 1. This is because, since the CQI can be important information/information that determines the size of part 2/information with a fixed size, the CQI is located in part 1, which is beneficial to avoid the loss of important information, or avoid blind detection of part 2.

In some possible implementations, the LI may be located in Part 1. This is because, since LI can be used as important information or information that determines the size of part 2, LI is located in part 1, which is beneficial to avoid the loss of important information, or avoid blind inspection of part 2.

In some possible implementations, the PMI can be located in part 2. This is because PMI is located in part 2 due to the characteristics of non-fixed size and large resource occupation overhead, which is beneficial to ensure the transmission of PMI.

In some possible implementations, the second indication information may be located in Part 1. This is because, since the second indication information can be used as important information or information that determines the size of part 2, the second indication information is located in part 1, which is beneficial to avoiding the loss of important information or blindly checking part 2.

(2) Group 0 (group 0) and group 1 (group 1) (optional)

In addition, since the interference measurement result information may include at least one of CSI-IM-based interference measurement results and NZP-CSI-RS-based interference measurement results, the following may exist:

If part 2 contains interference measurement result information, part 2 may contain group 0 and/or group 1. Among them, there are the following:

- If the terminal device is configured with CSI-IM, part 2 may contain CSI-IM-based interference measurement results, and the CSI-IM-based interference measurement results may be located in group 0.

- If the terminal device is not configured with CSI-IM, part 2 may not contain the interference measurement results based on CSI-IM; at this time, the interference measurement results based on NZP-CSI-RS may be in group 0.

- If the terminal device is configured with NZP-CSI-RS, Part 2 may contain interference measurement results based on NZP-CSI-RS, and based on NZP-CSI-RS The interference measurement results are in group 1.

- If the terminal device is not configured with NZP-CSI-RS, Part 2 may not contain interference measurement results based on NZP-CSI-RS.

In this embodiment of the present application, the value of y′ may be determined by the report type of the CSI report based on compression processing.

In some possible implementations, the value of y′ may be the same as or different from the value of y mentioned above.

(2)The value of k′

In this embodiment of the present application, the value of k′ may be determined based on the type of information contained in the first CSI report, which is based on compression processing. CSI report.

For example, the value of k′ can be determined by the type of information contained in the CSI report based on compression processing indicated by reportQuantity in CSI-ReportConfig.

In some possible implementations, the value of k′ may be the same as or different from the value of k mentioned above.

In some possible implementations, the value of k′ can be one of 0, 0.5, 1, 2, 3, etc.

In addition, in order to facilitate distinction and description, the embodiment of the present application may refer to k′ as the “first parameter”. Therefore, the priority of the CSI report based on compression processing may be determined by the first parameter, and the first parameter may be determined by the type of information contained in the CSI report based on compression processing (ie, the first CSI report).

(3)The value of c′

In this embodiment of the present application, the value of c′ may be consistent with the value of c mentioned above, that is, the value of c′ is the serving cell index value.

(4)The value of s′

In this embodiment of the present application, the value of s′ may be determined by the configuration identifier of the CSI report based on compression processing.

For example, the value of s′ is consistent with the value of s mentioned above, that is, the value of s′ is the value of reportConfigID in CSI-ReportConfig.

(5)The value of N′ _cells

In this embodiment of the present application, the value of N′ _cells may be determined by the maximum number of serving cells.

For example, the value of N' _cells can be consistent with the value of N _cells mentioned above, that is, the value of N' _cells is the value of maxNrofServingCells in CSI-ReportConfig.

In addition, in this embodiment of the present application, the value of N′ _cells may also be determined by the maximum number of serving cells configured with CSI reporting based on compression processing.

(6)The value of M′ _s

In this embodiment of the present application, the value of M′ _s may be determined by the maximum number of configurations of channel state information reports based on compression processing.

In addition, in this embodiment of the present application, the value of M′ _s may be determined by the maximum number of channel state information reports.

For example, the value of M′ _s can be consistent with the value of M _s , that is, the value of M′ _s is the value of maxNrofCSI-ReportConfigurations in CSI-ReportConfig.

(7)The value of a

In this embodiment of the present application, the value of a can be determined by the value range of k′. For example, if the value of k′ is one of 0 and 1, then the value of a can be 2; if the value of k′ can be one of 0, 0.5, 1, 2, and 3, then The value of a can be 5.

In some possible implementations, the value of a can be an integer greater than 1.

(8) Priority comparison

Since a compression-based CSI report is associated with a priority value, if the priority value Pri′ _CSI (a,y′,k′,c′,s′) associated with a compression-based CSI report is smaller than another The priority value associated with a compression-based CSI report is Pri′ _CSI (a, y′, k′, c′, s′), then the priority of the compression-based CSI report is higher than that of another compression-based CSI report. The priority of CSI report processing.

Since a compression-based CSI report is associated with a priority value, if the priority value Pri′ _CSI (a,y′,k′,c′,s′) associated with a compression-based CSI report is smaller than another If the priority value associated with a CSI report that is not based on compression processing is Pri _CSI (y, k, c, s), then the priority of the CSI report based on compression processing is higher than that of another CSI report that is not based on compression processing. priority.

(9) Priority between group 0 and group 1

Combined with the content in "4. CSI report on PUSCH under compression-based CSI feedback" above, if part 2 of the compression-based CSI report contains interference measurement result information, the interference measurement result information needs to be grouped.

In addition, in this embodiment of the present application, the priority of group 0 may be higher than the priority of group 1, that is, group 0 > group 1.

Therefore, when uplink feedback resources (ie, PUCCH/PUSCH carrying compression-based CSI reports) are limited and part 2 of the compression-based CSI reports needs to be discarded, the discarding is performed in order of priority, that is, priority is discarded. Group 1.

6. Under CSI feedback based on compression processing, the CPU occupied by CSI report

(1) The number of CPU occupied by a CPU report based on compression processing

Combined with the content in the above "②The number of CPUs occupied by a CSI report", the number of CPUs O' _CPU occupied by a CSI report based on compression processing can exist as follows:

①O′ _CPU =O _CPU

That is, the O′ _CPU is the same as the O _CPU described above. Therefore, it can exist as follows:

◆If the high-level parameter reportQuantity in CSI-ReportConfig is set to 'none', and the high-level parameter trs-Info is configured in CSI-RS-ResourceSet, then O' _CPU = 0. It should be noted that this method may or may not exist, and there is no specific restriction on this.

◆If the high-level parameter reportQuantity in CSI-ReportConfig is set to 'cri-RSRP', 'ssb-Index-RSRP', 'cri-SINR', 'ssb-Index-SINR' or 'none' (at this time CSI-RS- ResourceSet is not configured with high-level parameter trs-Info), then O′ _CPU =1. It should be noted that this method may or may not exist, and there is no specific restriction on this.

- If max(μ _PDCCH ,μ _CSI-RS ,μ _UL )<3, a CSI report is triggered aperiodic, L=0 CPUs are occupied, and the terminal device does not send a transmission block (or HARQ-ACK or both ), and this CSI corresponds to a single CSI with wideband frequency granularity, and corresponds to up to 4 CSI-RS ports in a single resource, with codebookType set to 'typeI-SinglePanel' (or reportQuantity set to 'cri-RI -CQI'), then O' _CPU =N _CPU . That is to say, the number of CPUs occupied by the CSI report based on compression processing is the total number of CPUs reported by the terminal device.

- Otherwise, O′ _CPU =K _s , where K _s is the number of NZP-CSI-RS resources (also called channel measurement resources) used for channel measurement in the NZP-CSI-RS-ResourceSet. That is to say, the number of CPUs occupied by the compression-based CSI report is the number of channel measurement resources associated with the compression-based CSI report.

②O′ _CPU ≠O _PPU

In other words, O' _CPU is not the same as the above-mentioned O _CPU .

③O′ _CPU can be determined by K _s

That is, O′ _CPU may be determined by the number of channel measurement resources associated with the compressed processed CSI report.

For example, O′ _CPU =K _s , O′ _CPU >K _s , O′ _CPU <K _s or O′ _CPU =K _s +σ. Among them, σ is the offset value specified by the preconfiguration, network configuration or protocol.

④O′ _CPU is the first value

The first value may be preconfigured, network configured, or specified by a protocol.

It should be noted that the first value can be understood as a fixed value, which is specified by pre-configuration, network configuration or protocol. In other words, the O′ _CPU is preconfigured, network configured, or specified by the protocol.

Of course, the first value can also be described using other terms, and there is no specific limitation on this.

(2) A CPU based on compression processing reports the number of OFDM symbols occupied by the occupied CPU.

It should be noted that the number of OFDM symbols occupied by the CPU reported based on compression processing can be compared with the above "③CPU occupied" The content in "Number of OFDM Symbols" is consistent and will not be described again.

7. CSI calculation time requirements for CSI reports under CSI feedback based on compression processing

Combined with the content in the above "(6) CSI calculation time requirements for CSI reports", the CSI calculation time requirements (Z _AI , Z′ _AI ) based on CSI reports can exist as follows:

①(Z _AI ,Z′ _AI )≠(Z(m),Z′(m))

That is, (Z _AI ,Z′ _AI ) is different from the above (Z(m), Z′(m)). In other words, (Z _AI ,Z′ _AI ) is different from the above (Z(m), Z′(m)).

For example, (Z _AI ,Z′ _AI )≠(Z ₁ ,Z′ ₁ ), or (Z _AI ,Z′ _AI )≠(Z ₂ ,Z′ ₂ ), or (Z _AI ,Z′ _AI )≠( Z ₃ ,Z′ ₃ ).

②(Z _AI ,Z′ _AI )=(Z(m),Z′(m))

That is, (Z _AI ,Z′ _AI ) is the same as (Z(m), Z′(m)) described above.

For example, (Z _AI ,Z′ _AI )=(Z ₁ ,Z′ ₁ ), or (Z _AI ,Z′ _AI )=(Z ₂ ,Z′ ₂ ), or (Z _AI ,Z′ _AI )=( Z ₃ ,Z′ ₃ ).

③(Z _AI ,Z′ _AI ) is determined by (Z(m),Z′(m))

That is to say, (Z _AI , Z′ _AI ) may have an associated (corresponding/mapping, etc.) relationship with (Z(m), Z′(m)).

For example, (Z _AI ,Z′ _AI )=(Z ₁ +Δz ₁ ,Z′ ₁ +Δz ₂ ), or (Z _AI ,Z′ _AI )=(Z ₂ +Δz ₃ ,Z′ ₂ +Δz ₄ ) , or (Z _AI ,Z′ _AI )=(Z ₃ +Δz ₅ ,Z′ ₃ +Δz ₆ ). Among them, Δz ₁ , Δz ₂ , Δz ₃ , Δz ₄ , Δz ₅ and Δz ₆ can be positive or negative values, and Δz ₁ , Δz ₂ , Δz ₃ , Δz ₄ , Δz ₅ and Δz ₆ can be preconfigured, Required by network configuration or protocol.

③Z _AI is the second value, and Z′ _AI is the third value

It should be noted that the second value can be understood as a fixed value, which is specified by preconfiguration, network configuration or protocol. The third value can be understood as a fixed value, which is specified by preconfiguration, network configuration or protocol.

Of course, the second value and the third value can also be described using other terms, and there is no specific limitation on this.

5. An example of a CSI report transmission method

To sum up, the following embodiments of the present application take the interaction between the terminal device and the network device as an example to introduce a channel state information report transmission method according to the embodiment of the present application. It should be noted that, as the execution subject of this method, the terminal device may also be a chip, chip module or module, etc. In other words, this method is applied to terminal equipment. Correspondingly, as the execution subject of this method, the network device can also be a chip, chip module or module, etc. In other words, this method is applied to network equipment.

As shown in Figure 2, it is a schematic flow chart of a channel state information report transmission method according to an embodiment of the present application, which specifically includes the following steps:

S210. The network device sends configuration information. The configuration information is used to determine the first CSI report. The first CSI report is a CSI report containing compressed information. The compressed information is information after the channel information has been compressed.

It should be noted that for "configuration information", "first CSI report", "compression information" and "channel information", please refer to the above "1. Channel information, compression information, configuration information, first CSI report and second CSI report" for details. "CSI Report" or other related content, we will not go into details here.

Correspondingly, the terminal device obtains the configuration information.

S220. The terminal device sends the first CSI report, and the first CSI report is sent according to the configuration letter. That is to say, the terminal device sends the first CSI report according to the configuration information.

Correspondingly, the network device receives the first CSI report, and the first CSI report is received according to the configuration information. That is to say, the network device receives the first CSI report according to the configuration information.

It can be seen that since the channel information may have characteristics such as a large number of bits, direct feedback of the channel information will result in more resources being occupied and signaling overhead. Therefore, the method of not directly feeding back the channel information is usually adopted. In order to reduce occupied resources and signaling overhead, embodiments of the present application adopt a method of compressing channel information, so that the compressed channel information (i.e., compressed information) has the characteristics of a smaller number of bits and higher accuracy.

In order to realize feedback of compressed information, embodiments of the present application use CSI reports to feedback compressed information, and introduce configuration information, so that the network device can send configuration information to the terminal device to determine the CSI report containing the compressed information (i.e., the first CSI report), and the network device can configure information to receive the first CSI report, and the terminal device can send the first CSI report according to the configuration information, thereby realizing feedback compression information through the transmission of the first CSI report, so that It is beneficial to reduce occupied resources, reduce signaling overhead and improve accuracy.

In some possible implementations, the channel information is obtained by the terminal device performing channel measurement through downlink reference signals.

It can be seen that the embodiments of the present application can perform channel measurement through downlink reference signals to obtain channel information.

In some possible implementations, the terminal device can compress the channel information based on the following methods to obtain compressed information:

The terminal device compresses the channel information through the artificial intelligence module to obtain compressed information. In other words, the compressed information is the information after the channel information has been compressed and processed by the artificial intelligence module.

It should be noted that, for details, please refer to the content in "(2) Compressed Information" above, which will not be described again.

It can be seen that since the AI module can establish solutions to some complex problems through training with a large amount of data, and has the ability to process large amounts of complex information/data and the ability to process with high accuracy, the embodiments of the present application can use the AI module to solve problems. The channel information is compressed in order to achieve compression of the channel information and ensure the accuracy of the compressed information.

In some possible implementations, the number of CSI processing units occupied by the first CSI report is a first value, and the first value is preconfigured, network configured, or specified by the protocol.

It should be noted that for details, please refer to the content in "6. CPU occupied by CSI report under CSI feedback based on compression processing" above, which will not be described again.

It can be seen that the embodiment of the present application can determine the number of CSI processing units occupied by the first CSI report as the first value through preconfiguration, network configuration, or protocol stipulation.

In some possible implementations, the number of CSI processing units occupied by the first CSI report is determined by the number of channel measurement resources associated with the first CSI report.

It can be seen that the embodiment of the present application can determine the number of CSI processing units occupied by the first CSI report through the number of channel measurement resources associated with the first CSI report.
