[0073] A terminal may also be referred to as user equipment (UE), terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc.

[0074] The network-side device 12 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0075] In some embodiments of the present application, the access network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of the present application, the network-side device may also be a base station located in a location such as land or water.

[0076] In some embodiments of the present application, the core network device may be referred to as a core network node, a core network element, or a core network function, for example, including but not limited to at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized Network Configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (Binding Support Function) Function, BSF), application function (Application Function, AF), etc. It should be noted that in the embodiment of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0077] In wireless communications, the movement of terminals or other objects in the communication environment can cause changes in the wireless channel. The base station uses real-time channel measurement information fed back by the terminals to select the terminal's transmission parameters, determine the terminal's modulation and coding scheme (MCS), and determine the terminal's beamforming or precoding information.

[0078] Channel information can include spatial dimension information such as Precoding Matrix Indicator (PMI) and Rank Indication (RI); or quality dimension information such as Channel Quantity Indicator (CQI), Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), and Signal to Interference plus Noise Ratio (SINR). Taking into account the transmission overhead of the wireless channel, PMI uses a quantized representation of the eigenvector of the bare channel; while CQI, RSRP, RSRQ, and RSSI are quantized representations of transmission quality. If the quantization step size is too large, the base station side will not be able to obtain rich channel information, and thus will not be able to allocate an MCS, beam, or precoding that better matches the channel to the terminal, thereby limiting the system throughput.

[0079] To facilitate understanding of the embodiments of the present application, the channel quality indicator (CQI) feedback related to the present application is explained.

[0080] In some scenarios, the supported CQI feedback includes wideband feedback and subband feedback. In practice, wideband CQI feedback is often used.

[0081] In some scenarios, CQI reporting under at least one of the following modulation modes may be supported:

[0082] Quadrature Phase Shift Keying (QPSK), 16QAM, 64QAM, 256QAM, and 1024QAM.

[0083] For example, a CQI report may include a CQI index, and one CQI index may correspond to a set of information: modulation, code rate, and efficiency.

[0084] To facilitate understanding of the embodiments of the present application, the hybrid automatic repeat request (HARQ) feedback related to the present application is explained.

[0085] After receiving the Physical Downlink Shared Channel (PDSCH), the terminal performs channel estimation based on the Demodulation Reference Signal (DMRS), demodulates the PDSCH based on the estimated channel, and further provides HARQ feedback based on the Cyclic Redundancy Check (CRC) check result. If the CRC check is correct, it indicates that the PDSCH demodulation is correct, and a positive acknowledgment (ACK) is fed back. If the CRC check is incorrect, it indicates that the PDSCH demodulation failed, and a negative acknowledgment (NACK) is fed back.

[0086] To facilitate understanding of the embodiments of the present application, the PMI feedback related to the present application is explained.

[0087] The terminal measures the transmission channel based on the Channel State Information Reference Signal (CSI-RS). It then uses the codebook type (e.g., type 1 or type 2) configured by the base station and the terminal's implementation algorithm to find the codebook identifier that best matches the channel and feeds it back to the base station.

[0088] The CQI feedback in related technologies has the following problems:

[0089] 1. The feedback cycle is dozens of scheduling cycles, and the feedback delay is long;

[0090] 2. CQI is obtained based on CSI-RS measurement and does not fully match the interference situation of PDSCH transmission;

[0091] 3. The determination of the CQI value is strongly related to the implementation algorithm on the terminal side. Generally, the base station cannot directly use it for MCS allocation after obtaining it.

[0092] The HARQ feedback in related technologies has the following problems:

[0093] HARQ feedback can only indicate whether a terminal successfully or unsuccessfully transmits a PDSCH using the MCS currently assigned by the network. For example, if a terminal is assigned MCS 9 and receives an ACK response, this only indicates that MCS levels 0 to 9 can be correctly received, but it is unknown whether MCS 10 can be correctly received. Similarly, if a terminal is assigned MCS 9 and receives a NACK response, this only indicates that MCS levels above 9 cannot be correctly received, but it is unknown whether MCS 8 can be correctly received. Therefore, HARQ feedback cannot indicate the MCS level that best matches the current channel, limiting the degree of match between the base station's assigned MCS and the actual wireless channel.

[0094] The PMI feedback in the related art performs excessive quantization processing on the wireless channel, which limits the matching degree between the precoding used by the base station and the actual wireless channel.

[0095] In summary, a channel information transmission method is needed that can take into account the feedback overhead of the terminal and obtain rich channel information on the network side.

[0096] The information transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0109] The seventh indication is used to indicate description information of the first channel information.

[0110] It should be noted that in the embodiments of the present application, the AI ​​unit may also be referred to as an AI model, an ML (machine learning) model, an ML unit, an AI structure, an AI function, an AI feature, a machine learning model, a neural network, a neural network function, a neural network function, etc., or an AI model may also refer to a processing unit that can implement specific algorithms, formulas, processing procedures, capabilities, etc. related to AI, or an AI model may be a processing method, algorithm, function, module or unit for a specific data set, or an AI model may be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as a graphics processing unit (GPU), a neural network processing unit (NPU), a tensor processing unit (TPU), an application specific integrated circuit (ASIC), etc. This application does not make any specific limitations on this.

[0111] In some embodiments, the first indication is used to indicate a processing method related to encoding, compression, modulation, feature extraction, denoising, etc. of the first channel information. The processing method may be related to the AI ​​unit, or may not be related to the AI ​​unit, or may be partially related to the AI ​​unit. That is, the processing of the first channel information may be entirely based on the AI ​​unit, or may be partially based on the AI ​​unit, or may not be based on the AI ​​unit, for example, using a traditional solution. When related to the AI ​​unit, the processing of the first channel information may be implemented by an AI unit that integrates multiple functions, or the processing of the first channel information may be implemented by multiple separate AI units, or the processing of the first channel information may be implemented by some functions by a separate AI unit and some functions by an AI unit that integrates multiple functions.

[0112] In some implementations, the first indication is used to indicate at least one of the following:

[0113] whether to perform joint coding on the first channel information;

[0114] whether the joint encoding of the first channel information includes source coding;

[0115] whether the joint encoding of the first channel information includes channel coding;

[0116] whether the joint encoding of the first channel information includes modulation;

[0117] whether the joint encoding of the first channel information includes nonlinear transformation compression processing;

[0118] whether the joint encoding of the first channel information includes denoising;

[0119] whether to perform nonlinear transformation compression processing on the first channel information;

[0120] whether to perform denoising processing on the first channel information;

[0121] whether to jointly encode the first channel information based on the AI ​​unit;

[0122] whether to perform source coding on the first channel information based on the AI ​​unit;

[0123] whether to perform channel coding on the first channel information based on the AI ​​unit;

[0124] whether to modulate the first channel information based on the AI ​​unit;

[0125] whether to perform nonlinear transformation and compression processing on the first channel information based on the AI ​​unit;

[0126] Whether to perform denoising processing on the first channel information based on the AI ​​unit.

[0127] Optionally, multiple processing methods for the first channel information may be predefined, and then the processing method for the first channel information may be indicated by indicating a processing method in the predefined methods.

[0128] Optionally, each of the above processing configurations may correspond to a corresponding indication bit, and different values ​​of the indication bit are used to indicate different processing methods.

[0129] For example, whether the first channel information is jointly encoded may correspond to 1 bit, and different values ​​of the 1 bit are used to indicate whether the first channel information is jointly encoded or not. Exemplarily, a value of 1 indicates that the first channel information is jointly encoded, and a value of 0 indicates that the first channel information is not jointly encoded.

[0130] For another example, whether the joint coding of the first channel information includes source coding may correspond to one bit, and different values ​​of the one bit are used to indicate whether the joint coding of the first channel information includes source coding and whether the joint coding of the first channel information does not include source coding. Exemplarily, a value of 1 indicates that the joint coding of the first channel information includes source coding, and a value of 0 indicates that the joint coding of the first channel information does not include source coding.

[0131] It should be understood that the first indication may include all of the above configurations, or may only indicate part of the configuration. When indicating part of the configuration, the remaining part may adopt the default configuration, which is not limited in this application.

[0132] For example, the first indication may explicitly indicate whether source coding, channel coding, modulation, joint coding, nonlinear transform compression processing, or denoising processing is performed on the first channel information based on the AI ​​unit, or it may be performed on the first channel information based on the AI ​​unit by default, or it may be performed on the first channel information based on the AI ​​unit by default without source coding, channel coding, modulation, joint coding, nonlinear transform compression processing, or denoising processing, or it may be performed on the first channel information based on the AI ​​unit by default, or it may be performed on the first channel information based on the traditional scheme by default. In this case, the first indication may not indicate whether source coding, channel coding, modulation, joint coding, nonlinear transform compression processing, or denoising processing is performed on the first channel information based on the AI ​​unit.

[0133] It should be noted that, when the first indication is used to indicate source coding, channel coding, modulation, joint coding, nonlinear transformation compression processing, or denoising processing of the first channel information, the traditional scheme is used by default to perform source coding, channel coding, modulation, joint coding, nonlinear transformation compression processing, or denoising processing on the first channel information, or, the first channel information is subjected to source coding, channel coding, modulation, joint coding, nonlinear transformation compression processing, or denoising processing based on the AI ​​unit by default, or, the first indication may explicitly indicate whether the AI ​​unit is used to perform source coding, channel coding, modulation, joint coding, nonlinear transformation compression processing, or denoising processing on the first channel information.

[0134] It should be noted that nonlinear compression transformation is a method of extracting data features and reducing data dimensions. Other feature extraction and compression methods can also be used, and this application does not limit this.

[0135] In some embodiments, the terminal may determine, according to the first indication, to perform the first operation on the first channel information.

[0136] For example, if the first indication is used to instruct to jointly encode the first channel information, the first operation includes jointly encoding the first channel information, where the joint encoding refers to joint encoding of information source encoding and information source encoding.

[0137] For another example, if the first indication is used to instruct to perform nonlinear transformation and compression processing on the first channel information, the first operation may include performing nonlinear transformation and compression processing on the first channel information.

[0138] For another example, if the first indication is used to indicate that the first channel information is jointly encoded based on the AI ​​unit, the first operation may include jointly encoding the first channel information based on the AI ​​unit.

[0139] For another example, if the first indication is used to indicate that the first channel information is not modulated based on the AI ​​unit, the first operation may include modulating the first channel information using a traditional scheme.

[0140] Exemplarily, the first operation may include at least one of the following operations:

[0141] jointly encoding the first channel information based on the first AI unit and modulating the first channel information based on the second AI unit;

[0145] performing source coding on the first channel information based on a third AI unit, performing channel coding on the first channel information based on a conventional scheme, and modulating the first channel information using a conventional scheme;

[0146] The first channel information is source-coded using a conventional scheme, channel-coded based on a conventional scheme, and modulated using a conventional scheme.

[0147] In some embodiments, the second indication is used to indicate valid time information of the first indication, or valid time information of the first operation, that is, the time during which the terminal can process the channel information based on the first indication.

[0148] Optionally, the first indication may be a semi-continuous configuration, or an aperiodic configuration, or a periodic configuration. For example, the validity period corresponding to the first indication may be a single time period, or a periodic time period.

[0150] period information of the first indication;

[0151] Valid time information corresponding to the first indication within a period.

[0152] In some embodiments, the validity period information corresponding to the first indication within a period may be indicated using a bitmap. For example, a period includes N time units, and the bitmap may include N bits, where N is a positive integer, and each bit corresponds to a time unit, such as a time slot. The value of each bit indicates whether the first indication is valid in the corresponding time unit. For example, a value of 1 indicates valid, and otherwise indicates invalid.

[0153] In some other embodiments, the valid time information corresponding to the first indication within a period may include at least one of the following:

[0154] A first duration, indicating the duration during which the first indication is valid within a period;

[0155] A first ratio indicates the ratio of the effective duration of the first indication in a cycle to the duration of the cycle;

[0156] The first offset indicates a starting position where the first indication becomes valid within a cycle.

[0157] In some embodiments, the first information includes multiple first indications, that is, the first information indicates multiple first operations. Optionally, the multiple first indications correspond to different time periods within a cycle, or in other words, different first operations are performed in different time periods within a cycle, for example, the first channel information is processed based on a certain first operation in a first time period within a cycle, and the first channel information is processed based on another first operation in a second time period within the cycle.

[0158] Optionally, different first operations may correspond to different processing objects, or different first indications may correspond to different processing objects, or the first information includes first indications for different processing objects, or first operations for processing different objects.

[0159] For example, the multiple first indications may include a first indication for processing a first object and a first indication for processing a second object; wherein the first object may be a first measurement quantity, such as the transmission error probability of all levels of MCS; the second object may be a second measurement quantity, such as the difference between the current transmission error probability of all levels of MCS and a reference measurement quantity, and the reference measurement quantity may be, for example, a measurement quantity corresponding to the first channel information.

[0160] In some embodiments, the third indication is used to indicate a method for obtaining the first channel information, or in other words, the network-side device instructs (or configures or allows) the terminal to obtain the first channel information. For example, the third indication is used to indicate whether the first channel information is obtained through measurement or prediction. That is, the network-side device instructs, configures, or allows the terminal to obtain the first channel information through measurement or prediction.

[0161] It should be noted that when the third indication is used to indicate that the first channel information is obtained through measurement, it can be considered that the first channel information does not include the predicted channel information. For example, the first channel information can be obtained directly through measurement, or it can be obtained by processing the measurement results. The processing here does not include prediction. In this case, the time-frequency resources corresponding to the first channel information are no more than the time-frequency resources corresponding to the measurement; when the third indication is used to indicate that the first channel information is obtained through prediction, it can be considered that the first channel information includes the predicted channel information and the measured channel information, that is, the first channel information can be composed of the predicted channel information and the measured channel information. In this case, the time-frequency resources corresponding to the first channel information are more than the time-frequency resources corresponding to the measurement.

[0162] In some embodiments of the present application, the method 200 further includes:

[0163] The first channel information is acquired according to the third indication and the second channel information, wherein the second channel information is obtained by measuring a reference signal. The second channel information is also called channel measurement information or measurement information.

[0164] For example, if the third indication is used to indicate that the first channel information is obtained through measurement, the terminal can use the second channel information as the first channel information, or process the first channel information to obtain the first channel information, wherein the time-frequency resources corresponding to the first channel information (for example) are the same as the time-frequency resources corresponding to the second channel information, or the time-frequency resources corresponding to the first channel information are part of the time-frequency resources corresponding to the second channel information. For example, the time slot and physical resource block (PRB) corresponding to the first channel information are the same as the time slot and PRB corresponding to the second channel information. For another example, the time slot and PRB corresponding to the first channel information are part of the time slot and PRB corresponding to the second channel information.

[0165] For another example, if the third indication is used to indicate that the first channel information is obtained by prediction, the terminal may perform prediction based on the second channel information to obtain the first channel information, wherein the time-frequency resources corresponding to the first channel information are more than the time-frequency resources corresponding to the second channel information. For example, the terminal may perform prediction based on the second channel information to obtain channel information that occupies more time domain resources (e.g., time slots) and / or more frequency domain resources (e.g., PRBs), and use the channel information as the first channel information.

[0166] In an embodiment of the present application, the first channel information, or the information source for semantic communication transmission of channel information, may be channel measurement information, or may be obtained by processing the channel measurement information, or may be obtained by predicting the channel measurement information.

[0167] In some embodiments, the fourth indication is used to indicate at least one of the following measurement quantities:

[0168] Signal-to-interference-and-noise ratio SINR;

[0169] Reference signal received power RSRP;

[0170] Reference signal received quality RSRQ;

[0171] Received signal strength indication RSSI;

[0172] Channel quality indication CQI;

[0173] Precoding matrix indicator PMI;

[0174] HARQ information of the physical downlink channel (e.g. PDSCH);

[0175] Statistical information of transmission results obtained by transmitting a physical downlink channel (eg, PDSCH) based on at least one MCS.

[0176] In some embodiments, the measurement quantity indicated by the fourth indication may be a measurement quantity that the network side device instructs (or configures, or allows) the terminal to use, that is, the network side device instructs or configures or allows the terminal to use the at least one measurement quantity to obtain the third information.

[0177] Optionally, when the first information does not include the fourth indication, the terminal may use a default measurement quantity. Optionally, the default measurement quantity may be RSRP, CQI, or PMI, etc., which is not limited in this application. Alternatively, the terminal may use channel measurement information, that is, obtain the measurement quantity without processing the channel measurement information.

[0178] In some embodiments, the fourth indication may explicitly indicate at least one measurement quantity, or a combination of measurement quantities, or may implicitly indicate at least one measurement quantity or a combination of measurement quantities, such as an identifier corresponding to the measurement quantity, or an identifier of the combination of measurement quantities. This application does not limit the specific indication method.

[0179] In some embodiments of the present application, the method 200 further includes:

[0180] The second channel information is processed according to the measurement amount indicated by the fourth indication to obtain at least one measurement amount, wherein the first channel information includes the at least one measurement amount, and the second channel information is obtained by measuring a reference signal.

[0181] In some embodiments, the statistical information of the transmission result obtained based on at least one MCS transmission physical downlink channel (eg, PDSCH) may be statistical information obtained through measurement, or may also be predicted statistical information.

[0182] Optionally, the statistical information may be a probability of successful PDSCH transmission or a probability of transmission failure based on at least one MCS.

[0183] In some embodiments, the at least one MCS may include at least one MCS, and the at least one MCS may be the MCS actually assigned by the network-side device in multiple transmissions, or may include all MCSs supported by the terminal (or all-level MCSs), or the at least one MCS includes the MCS actually assigned by the network-side device and also includes the MCS level for instructing the terminal to make a prediction. For example, the terminal may predict statistical information (for example, the probability of correct transmission or the probability of transmission error) of PDSCH transmission corresponding to more MCS levels based on the demodulation result (i.e., demodulation success or failure) of PDSCH demodulation based on the MCS actually assigned by the network-side device, the DMRS channel measurement result or the channel estimation result of the PDSCH.

[0184] In some embodiments, when the first channel information is obtained through measurement and the terminal does not process the channel measurement information when acquiring the first channel information, the first channel information may include at least one of the following:

[0185] Downlink reference signal measurement results, such as CSI-RS measurement results and PDSCH DMRS measurement results.

[0186] In some embodiments, when the first channel information is obtained through measurement and the terminal processes the channel measurement information (for example, processes it into at least one measurement quantity according to the fourth indication) when acquiring the first channel information, the first channel information may include at least one of the following measurement quantities:

[0187] CSI-RS measurement quantities, such as SINR, RSRP, RSRQ, and RSSI;

[0188] PDSCH DMRS measurement quantity, such as SINR;

[0189] HARQ information corresponding to the MCS assigned by the network side device obtained based on PDSCH demodulation.

[0190] In some embodiments, when the first channel information is obtained through prediction, the first channel information may include at least one of the following measurement quantities:

[0191] The measurement quantities corresponding to more time-frequency resources, such as SINR, RSRP, RSRQ, and RSSI, are predicted based on the CSI-RS measurement results.

[0192] The measurement quantity corresponding to more time-frequency resources, such as SINR, is predicted based on the PDSCH DMRS measurement results;

[0193] Statistical information of PDSCH transmission results corresponding to more MCSs, such as the probability of successful PDSCH transmission and the probability of failed PDSCH transmission, predicted based on the PDSCH transmission result corresponding to at least one MCS. This statistical information may include the time domain resources where the PDSCH transmission is located (e.g., the time slot where the PDSCH is located) in the time domain, and may also include future time domain resources. In the frequency domain, it may include the frequency domain resources where the PDSCH transmission is located (e.g., the PRB where the PDSCH is located), and may also include more frequency domain resources.

[0194] Figures 3 to 8 illustrate schematic diagrams of several processing methods on the terminal side (i.e., the transmitter side) and the network side (i.e., the receiver side) provided in the embodiments of the present application. It should be understood that the processing methods illustrated in Figures 3 to 8 are examples. In other embodiments, the terminal and the network side device may also adopt other processing methods, and this application does not limit this. It should be noted that the processing methods of the terminal and the network side device correspond to each other. For example, the terminal processes the first channel information based on the first information to obtain the third information. After obtaining the third information, the network side device can perform corresponding reverse processing on the third information according to the first information to obtain the recovered first channel information.

[0195] In the example of Figure 3, the terminal uses processing mode 1. In processing mode 1, the terminal does not perform joint coding on the first channel information. Instead, the terminal performs channel coding and modulation on the first channel information. The first channel information is obtained by processing the second channel information (e.g., the measurement result of the downlink reference signal). For example, the second channel information is processed according to the fourth indication to obtain at least one measurement quantity. This at least one measurement quantity is included as the first channel information in uplink control information (UCI), which is then carried in the physical uplink control channel (PUCCH). It is then channel coded and modulated to become third information, which is then transmitted through the transmitter. After receiving the third information, the network-side device, as the receiving end, first demodulates it, then performs channel decoding, and then decodes the PUCCH to recover the first channel information. In this case, the channel information recovered by the network-side device is at least one measurement quantity.

[0196] In the example of Figure 4, the terminal uses processing method 2. This processing method 2 differs from processing method 1 in that the first channel information is the second channel information, that is, the terminal does not process the second channel information. In this case, the channel information recovered by the network-side device is the second channel information, that is, the first channel information.

[0197] In the example of Figure 5, the terminal adopts processing mode 3, wherein in processing mode 3, the terminal jointly encodes the first channel information, wherein the joint encoding includes or does not include modulation, and the first channel information is obtained by processing the second channel information (for example, the measurement result of the downlink reference signal), for example, the second channel information is processed according to the fourth indication to obtain at least one measurement quantity. The at least one measurement quantity is included in the second information, and the second information is jointly encoded and modulated by the source channel to become the third information, which is sent out through the transmitter. After the network-side device receives the third information as the receiving end, it first demodulates and then performs joint decoding of the source channel to recover the first channel information. In this case, the channel information recovered by the network-side device is at least one measurement quantity.

[0198] In the example of Figure 6, the terminal uses processing mode 4. This processing mode 4 differs from processing mode 3 in that the first channel information is the second channel information, that is, the terminal does not process the second channel information. In this case, the channel information recovered by the network-side device is the second channel information, that is, the first channel information.

[0199] In the example of Figure 7, the terminal adopts processing mode 5, wherein in processing mode 5, the terminal performs joint coding on the first channel information, wherein the joint coding includes source channel joint coding and modulation, and the first channel information is obtained by processing the second channel information (for example, the measurement result of the downlink reference signal), for example, the second channel information is processed according to the fourth indication to obtain at least one measurement quantity. The at least one measurement quantity is included in the second information, and the second information becomes the third information after being jointly coded with the source channel (the joint coding already includes modulation) and is sent out through the transmitter. After the network-side device receives the third information as the receiving end, it first performs source channel joint decoding (the joint decoding already includes demodulation) to recover the first channel information. In this case, the channel information recovered by the network-side device is at least one measurement quantity.

[0200] In the example of Figure 8, the terminal uses processing method 6. This processing method 6 differs from processing method 5 in that the first channel information is the second channel information, that is, the terminal does not process the second channel information. In this case, the channel information recovered by the network-side device is the second channel information, that is, the first channel information.

[0201] It should be understood that the various processes in Figures 3 to 8 can be implemented using AI units or based on traditional solutions, and this application does not limit this. Before the first channel information enters the source coding, it can also include feature extraction operations, such as nonlinear compression; source-channel joint coding or source coding can also include denoising operations, which this application does not limit.

[0202] In some embodiments, the fifth indication is used to indicate at least one of the following measurement purposes:

[0203] Used to measure channel quality (or to obtain channel quality information predicted by the terminal), to assign a modulation and coding scheme (MCS) to the terminal, to assign precoding information to the terminal, and to schedule terminal selection. Optionally, when the first information does not include the fifth indication, the terminal may consider the measurement purpose to be a default measurement purpose. Optionally, the default measurement purpose may be for obtaining channel quality, etc., which is not limited in this application.

[0204] In some embodiments, the fifth indication may explicitly indicate at least one measurement purpose, or a combination of measurement purposes, or may implicitly indicate at least one measurement purpose or a combination of measurement purposes, such as an identifier corresponding to the measurement purpose, or an identifier of the combination of measurement purposes. This application does not limit the specific indication method.

[0205] In some embodiments, the terminal may obtain first channel information having a stronger correlation with the measurement purpose according to the fifth indication. For example, the terminal may determine first channel information having a stronger correlation with the measurement purpose from the second channel information according to the measurement purpose.

[0206] For example, when the measurement purpose indicated by the fifth indication is to allocate an MCS to the terminal, the terminal may determine the corresponding MCS level with the goal of maximizing the effective transmission rate:

[0207] Among them, R l is the transmission rate or spectrum efficiency corresponding to MCS level l, p NACK,l is the transmission error probability corresponding to MCS level l; R l (1-p NACK,l ) is the effective transmission rate corresponding to MCS level 1.

[0208] For example, the terminal can calculate several MCSs that maximize the effective transmission rate according to the above formula, and then only feed back the identifiers of these several MCSs and the corresponding transmission error probabilities to the network side, without transmitting the transmission error probabilities corresponding to all MCS levels, thereby saving transmission overhead.

[0209] That is, the first channel information may include identifiers of the multiple MCSs of the terminal and corresponding transmission error probabilities.

[0210] In some embodiments, the at least one measurement quantity indicated by the fourth indication is associated with one measurement purpose, or is associated with multiple measurement purposes, that is, multiple measurement purposes can use the same set of measurement quantities. Optionally, the measurement quantities associated with different measurement purposes can be the same, or different.

[0211] For example, channel quality-related measurement quantities (eg, SINR, RSRP, RSRQ, RSSI), or the probability of correct or erroneous PDSCH transmission corresponding to at least one MCS, etc., can be used to determine channel quality.

[0212] As shown in Figure 9, the first channel information may include the transmission failure probability of the PDSCH corresponding to the full-order MCS (i.e., all MCS levels), which is denoted as X1. After processing by the sixth AI unit, it is Z1=G1(X1), where G1() represents the mapping processing function of the sixth AI unit. It is then modulated and sent to the base station. The base station demodulates to obtain Z1', and then the recovered X1' (first channel information) is obtained after inference by the seventh AI unit on the base station side, such as the transmission failure probability of the PDSCH corresponding to the full-order MCS.

[0213] For example, measurement quantities related to spatial information (such as PMI, RI, etc.) can be used to allocate precoding information to the terminal, and statistical probability information of PDSCH transmission failure or correct transmission corresponding to at least one MCS can be used to allocate MCS to the terminal.

[0214] As shown in Figure 10, the first channel information may include the transmission failure probability of the PDSCH corresponding to the full-order MCS, denoted as X2. After processing by the eighth AI unit, it is Z2=G2(X2), where G2() represents the mapping processing function of the eighth AI unit. It is then modulated and sent to the base station. The base station demodulates to obtain Z2', and then the information on the base station side and Z2' are simultaneously used as inputs of the ninth AI unit. The AI ​​unit performs inference to obtain an inference result, for example, the MCS assigned to the terminal.

[0215] For example, when the second information obtained by the base station is used to determine downlink precoding information of the terminal, the information on the base station side may include channel information obtained based on an uplink reference signal (eg, SRS).

[0216] For another example, when the second information obtained by the base station is used to determine the MCS of the terminal, the information on the base station side may include MSC information used for uplink transmission, or channel quality obtained based on an uplink reference signal.

[0217] For another example, when the base station obtains the second information for determining the scheduled user (or the scheduled terminal), the user MCS (or the terminal MCS) and the user's precoding (or the terminal's precoding), the information on the base station side may include historical user scheduling information (or terminal scheduling information), historical user transmission rate information (or terminal transmission rate information), channel information obtained based on the uplink reference signal (for example, SRS), etc.

[0218] For another example, measurement quantities related to channel quality (such as SINR, RSRP, RSRQ, and RSSI) can be used to determine channel quality and can also be used to allocate MCS and / or precoding information to a terminal.

[0219] That is, multiple measurement purposes can share a set of first channel information.

[0220] As shown in Figure 11, the first channel information may include CSI-RS and / or PDSCH DMRS measurement results, denoted as X3. After processing by the tenth AI unit, the result is Z3 = G3(X3), where G3() represents the mapping function of the tenth AI unit. This information is then modulated and sent to the base station. The base station demodulates the information to obtain Z3', which then serves as input to the eleventh AI unit on the base station side. This AI unit performs inference to obtain an inference result, such as allocating MCS and precoding information to the terminal. This means that two measurement objectives are simultaneously included.

[0221] It should be understood that in the examples of Figures 9 to 11, the AI ​​unit on the terminal side (for example, the sixth AI unit, the eighth AI unit, and the tenth AI unit) may also include a modulation unit, that is, the modulation function can be implemented by the AI ​​unit, or the AI ​​unit may include a denoising unit, or it may also include a nonlinear transformation compression unit (or called a feature extraction unit). The AI ​​units on the network side (for example, the seventh AI unit, the ninth AI unit, and the eleventh AI unit) and the AI ​​units on the terminal side correspond to each other and can be adjusted accordingly according to the functions of the AI ​​units on the terminal side. This application does not limit this.

[0222] In some embodiments of the present application, the sixth indication includes but is not limited to at least one of the following:

[0223] whether to use verification information to verify the first channel information;

[0224] A verification method for the verification information;

[0225] Whether to compress the verification information;

[0226] Whether to perform the same processing on the verification information and the first channel information.

[0227] In some embodiments, when the sixth indication is used to indicate that the first channel information is to be verified using verification information, the first information includes the verification information of the first channel information.

[0228] In some embodiments, the verification method of the verification information may refer to a method for generating the verification information based on the first channel information. It should be understood that this application does not limit the specific indication method of the verification method. For example, the verification method may adopt a verification function, an executable program, or an AI unit for verification. It should also be understood that the verification method of the verification information may be indicated in an explicit or implicit manner, and this application does not limit this.

[0229] For example, the verification function indication may be used to indicate a target verification function in at least one predetermined verification function. For example, each verification function corresponds to an index or identifier, and the verification function indication may be used to indicate the index or identifier, or may directly indicate a specific verification function.

[0230] For another example, the executable program indication may be used to indicate a target executable program among at least one predetermined executable program. For example, each executable program corresponds to an index or identifier, and the executable program indication may be used to indicate the index or identifier, or may directly indicate a specific executable program.

[0231] For another example, the AI ​​unit indicator can be used to indicate a target AI unit among at least one predetermined AI unit for verification. For example, each AI unit corresponds to an index or identifier, and the AI ​​unit indicator can be used to indicate the index or identifier, or can directly indicate parameters of a specific AI unit.

[0232] In some embodiments, the sixth indication is used to indicate that the verification information is to be transmitted and processed differently from the first channel information, for example, using traditional channel coding and traditional modulation. Alternatively, the same transmission processing may be used for the verification information and the first channel information. This application does not limit this.

[0233] In some embodiments, when the sixth indication is used to indicate that the verification information is to be processed in the same manner as the first channel information, the terminal may process the verification information based on the first indication, for example, inputting the first channel information and the verification information together into the corresponding module for processing. For the specific processing method, please refer to the relevant description of the aforementioned embodiment. For the sake of brevity, it will not be repeated here.

[0234] In some embodiments, the verification information can be used to determine the recovery performance of the channel information, or the transmission recovery performance of the first channel information. For example, when the terminal and the network-side device process the channel information based on the AI ​​unit, the network-side device can monitor the transmission performance corresponding to the first indication based on the verification information, for example, to determine the transmission recovery performance of the transmission mode corresponding to the first indication. If the transmission mode corresponding to the first indication is implemented by the AI ​​unit, the reasoning performance of the AI ​​unit is reflected.

[0235] The following describes the behavior of the terminal and network-side devices in combination with two methods of processing verification information.

[0236] Case 1: The terminal processes the verification information in a different way than the first channel information

[0237] In some embodiments, the terminal may generate verification information according to the verification method.

[0238] For example, if the first channel information is represented by X, the terminal can generate verification information Y based on a verification function f() known to the network side device, that is, Y=F(), or can also generate the verification information Y based on an executable program known to the network side device or an AI unit known to the network side device, which is not limited in this application. The terminal can also process the first channel information to obtain Z=G(X).

[0239] In this embodiment, the terminal uses the verification information as auxiliary information and does not process it based on the transmission mode of the first indication, but uses traditional channel coding and debugging to align and process it to ensure lossless transmission of the verification information. For example, the terminal can send Y and Z together to the network side device, that is, the third information includes Y and Z. After the network side device receives Z, it can perform corresponding reverse processing on Z to obtain X', and then the network side device calculates Y'=F(X') based on the verification function F() and X'. The network side device determines the similarity of X and X' by comparing the difference between Y and Y', thereby determining the recovery performance of the first channel information of the transmission mode corresponding to the first indication. If the transmission mode corresponding to the first indication is implemented by an AI unit, the reasoning performance of the AI ​​unit is reflected. Among them, because the verification information is lossless transmission, the Y recovered by the network side and the Y at the sending end are the same.

[0240] Case 2: Perform the same transmission processing on the verification information and the first channel information

[0241] In some embodiments, the terminal may generate verification information according to the verification method. For example, if the first channel information is represented by X, the verification information Y may be generated based on a verification function F() known to the network side device, i.e., Y=F(). Alternatively, the verification information Y may be generated based on an executable program known to the network side device or an AI unit known to the network side device, which is not limited in this application.

[0242] In this embodiment, the terminal may process Y and X together into W through the transmission operation corresponding to the first indication and then send the result to the network device, i.e., the third information includes W. After receiving W, the network device reversely processes W to recover X' and Y'. The network device then calculates Y" = F(X') based on the check function F() and X'. The network device determines the similarity between X and X' by comparing the difference between Y" and Y', thereby determining the recovery performance of the first channel information using the transmission mode corresponding to the first indication. If the transmission mode corresponding to the first indication is implemented by an AI unit, the reasoning performance of the AI ​​unit is reflected.

[0243] In some embodiments, the seventh indication is used to indicate description information of the first channel information, for example, including data format information of the first channel information. The data format information of the first channel information may include at least one of the following:

[0244] The input order of at least one measurement quantity, dimension information of the at least one measurement quantity, and accuracy information of the at least one measurement quantity. However, when the terminal uses an AI unit to process the first channel information, the description information of the first channel information can be understood as description information related to the AI ​​unit. Optionally, the description information of the first channel information can also include preprocessing information of the at least one measurement quantity. This preprocessing information can be used to indicate the preprocessing method used to obtain the at least one measurement quantity.

[0245] In some embodiments, the first information further includes at least one of the following:

[0246] an eighth indication, used to indicate a processing method for the first channel information, or used to indicate a comparative monitoring scheme adopted by the terminal, wherein the processing methods indicated by the eighth indication and the first indication are different;

[0247] The ninth indication is used to instruct the terminal to feed back at least one channel information, for example, feeding back the channel information obtained by processing the first channel information based on the first indication and the channel information obtained by processing the first channel information based on the eighth indication.

[0248] In some embodiments, when the first information does not include the sixth indication, the first information includes the eighth indication; or, when the sixth indication is used to indicate not to use verification information to verify the first channel information, the first information includes the eighth indication.

[0249] In some embodiments, the eighth indication may be used to indicate at least one of the following:

[0250] whether to perform joint coding on the first channel information;

[0251] whether the joint encoding of the first channel information includes source coding;

[0252] whether the joint encoding of the first channel information includes channel coding;

[0253] whether the joint encoding of the first channel information includes modulation;

[0254] whether the joint encoding of the first channel information includes nonlinear transformation compression processing;

[0255] whether the joint encoding of the first channel information includes denoising;

[0256] whether to perform nonlinear transformation compression processing on the first channel information;

[0257] whether to perform denoising processing on the first channel information;

[0258] whether to jointly encode the first channel information based on the AI ​​unit;

[0259] whether to perform source coding on the first channel information based on the AI ​​unit;

[0260] whether to perform channel coding on the first channel information based on the AI ​​unit;

[0261] whether to modulate the first channel information based on the AI ​​unit;

[0262] whether to perform nonlinear transformation and compression processing on the first channel information based on the AI ​​unit;

[0263] Whether to perform denoising processing on the first channel information based on the AI ​​unit.

[0264] In some embodiments, the terminal may determine, based on the eighth indication, to perform a second operation on the first channel information, where the second operation is different from the first operation.

[0265] Exemplarily, the second operation may include at least one of the following operations:

[0266] jointly encoding the first channel information based on a twelfth AI unit and modulating the first channel information based on a thirteenth AI unit;

[0267] performing joint encoding on the first channel information based on a twelfth AI unit and modulating the first channel information using a traditional scheme;

[0268] performing source coding on the first channel information based on a fourteenth AI unit, performing channel coding on the first channel information based on a fifteenth AI unit, and modulating the first channel information based on a sixteenth AI unit;

[0269] performing source coding on the first channel information based on a fourteenth AI unit, performing channel coding on the first channel information based on a fifteenth AI unit, and modulating the first channel information using a traditional scheme;

[0270] performing source coding on the first channel information based on a fourteenth AI unit, channel coding on the first channel information using a conventional scheme, and modulating the first channel information using a conventional scheme;

[0271] The first channel information is source-coded using a conventional scheme, channel-coded using a conventional scheme, and modulated using a conventional scheme.

[0272] Exemplarily, the first operation may include jointly encoding the first channel information based on the first AI unit and modulating the first channel information based on the second AI unit, and the second operation may include at least one of the following:

[0273] performing joint encoding on the first channel information based on a twelfth AI unit and modulating the first channel information using a traditional scheme;

[0277] The first channel information is source-coded using a conventional scheme, channel-coded using a conventional scheme, and modulated using a conventional scheme.

[0278] In some embodiments, the processing scheme indicated by the eighth indication and the processing scheme indicated by the first indication can be used as a comparison scheme to monitor transmission performance based on the first indication, for example, to determine the transmission recovery performance of the transmission method corresponding to the first indication. If the transmission method corresponding to the first indication is implemented by an AI unit, the reasoning performance of the AI ​​unit is reflected.

[0279] In some embodiments, the method 200 further includes:

[0280] The terminal processes the first channel information according to the first instruction to obtain fourth information;

[0281] The terminal processes part or all of the first channel information according to the eighth indication to obtain fifth information; wherein the third information includes the fourth information and the fifth information.

[0282] Optionally, when the fifth information is obtained by processing part of the information in the first channel information, the third information also includes a tenth indication for indicating the position of the part of the information in the first channel information, or the terminal processes the information of the default position in the first channel information (the network side device knows the position, that is, the terminal and the network side device have the same understanding of the position). In this case, the third information may not include the tenth indication.

[0283] In some embodiments, if the third information includes fourth information and fifth information, wherein the fifth information is obtained by processing the first channel information according to the eighth indication, the method 200 further includes:

[0284] The network side device decodes the fourth information and the fifth information respectively to obtain the eighth information and the ninth information; based on the eighth information and the ninth information, the performance of transmission recovery of the first channel information is determined. For example, when the first channel information is measured based on the AI ​​unit, it can be used to monitor the reasoning performance of the AI ​​unit.

[0285] In some other embodiments, if the third information includes fourth information, fifth information, and a tenth indication, wherein the fifth information is obtained by processing part of the first channel information according to the eighth indication, and the tenth indication is used to indicate the position of the part of the information in the first channel information, the method 200 further includes:

[0288] Based on the partial information of the eighth information and the tenth information, the performance of transmission recovery of the first channel information is determined. For example, when the first channel information is processed based on the AI ​​unit, it can be used to monitor the reasoning performance of the AI ​​unit.

[0289] In some embodiments, the eleventh indication can be used to indicate a specific pattern in at least one predetermined pattern. For example, each predetermined pattern corresponds to an index or identifier. The eleventh indication can indicate the index or identifier of the specific pattern, or it can also explicitly indicate the specific content of the specific pattern, or it can also indicate the position of the partial information in the first channel information in a bitmap manner, or it can also indicate the starting position of the partial information in the first channel information, continuous length and other information. This application does not limit the specific indication method.

[0290] The following describes two monitoring methods with reference to specific examples.

[0291] Example 1:

[0292] Assume that the first channel information is X, and the information obtained by the terminal after processing the first channel information based on the first indication is Z=G(X). The information obtained by the terminal after processing the first channel information based on the eighth indication is O=H(X). The terminal can send both Z and O to the network-side device, that is, the third information may include Z and O. After receiving Z and O, the network-side device can perform corresponding reverse processing on Z and O to obtain X' and X". The network-side device can determine the transmission recovery performance of the first channel information based on the difference between X' and X", such as the recovery similarity of the first channel information. For example, when processing the first channel information based on the AI ​​unit, the inference performance of the AI ​​unit can be determined based on the difference between X' and X".

[0293] Example 2:

[0294] Assuming that the first channel information is X, the terminal obtains information Z=G(X) after processing the first channel information based on the first instruction, and the terminal processes part of the first channel information (denoted as X) based on the eighth instruction. P ) is processed and the information obtained is O P =H(X P ), the terminal can Z and O P are all sent to the network side device, that is, the third information may include Z and O P Optionally, the third information may further include an eleventh indication for indicating the position of the partial information in X. After receiving the third information, the network side device may perform the operations on Z and O in the third information. P Perform the corresponding reverse processing to obtain X' and X P ", then obtain part of the content X in X' according to the eleventh instruction or based on a predefined method P '. By contrast X P ' and X P"The difference between X' and X" is used to determine the transmission recovery performance of the first channel information, such as the recovery similarity of the first channel information. For example, when the first channel information is processed based on the AI ​​unit, the reasoning performance of the AI ​​unit can be determined according to the difference between X' and X".

[0295] In other embodiments, the eighth indication is used to indicate a comparison scheme used for monitoring, for example, the eighth indication is used to indicate an MCS error probability transmission scheme based on differential feedback. That is, the MCS error probability transmission scheme based on differential feedback is used as the comparison scheme.

[0296] In the following, a description is given of a specific embodiment by taking a differential feedback scheme using MCS transmission error probability as an example for comparison and monitoring.

[0297] In this embodiment, the measurement purpose indicated by the fifth indication is to determine the MCS of the terminal, and the measurement quantity indicated by the fourth indication is the transmission error probability corresponding to the MCS level. Assume that the terminal determines part of the MCS as the first channel information according to the maximum effective rate criterion.

[0298] At this time, the eighth indication may indicate an MCS error probability transmission scheme based on differential feedback.

[0299] Combining several ways of reporting information by the terminal, the processing process on the terminal side is explained.

[0300] Method 1: Only report the transmission error probability of the MCS level, without reporting the MCS identifier

[0301] Step 1: The terminal sorts the MCS levels according to the MCS levels included in the first channel information and in ascending or descending order according to the MCS identifier (which may be configured in the first indication or the eighth indication, or agreed in the protocol), and uses the first MCS as the reference MCS;

[0302] Step 2: The terminal quantizes the transmission error probability of the reference MCS (the quantization method can be equal interval quantization or unequal interval quantization);

[0303] Step 3: The terminal calculates the transmission error probability of the remaining MCS minus the reference MCS, and then quantizes the difference; (the quantization method can be equal interval quantization or unequal interval quantization);

[0304] Step 4: Include the quantized reference MCS transmission error probability and the quantized difference into the UCI, carry it into the PUCCH or PUSCH, and send it to the network.

[0305] Method 2: Report the transmission error probability of the MCS level and the MCS identifier.

[0306] Step 1: The terminal sorts the MCS levels included in the first channel information in ascending or descending order according to the transmission error probability of the MCS (which can be configured in the first indication or the eighth indication, or agreed in the protocol), and uses the first MCS as the reference MCS.

[0307] Step 2: The terminal quantizes the transmission error probability of the reference MCS; (the quantization method can be equal interval quantization or unequal interval quantization)

[0308] Step 3: The terminal calculates the error probability of the remaining MCS minus the reference MCS, and then quantizes the difference. (The quantization method can be equal interval quantization or unequal interval quantization)

[0309] Step 4: Include the quantized reference MCS transmission error probability, the quantized difference, the reference MCS identifier, and the identifiers of the remaining MSCs into the UCI, carry it into the PUCCH or PUSCH, and send it to the network.

[0310] Method 3: Report the transmission error probability of the MCS level and the MCS identifier.

[0311] The difference from method 2 is that method 2 determines the reference MCS according to the transmission error probability of the MCS, while method 3 determines the target MCS according to the maximum effective transmission rate.

[0312] Step 1: The terminal sorts the MCS levels included in the first channel information in descending order according to the maximum effective transmission rate, and uses the first MCS as a reference MCS.

[0313] Step 2: The terminal quantizes the transmission error probability of the reference MCS; (the quantization method can be equal interval quantization or unequal interval quantization)

[0314] Step 3: The terminal calculates the error probability of the remaining MCS minus the reference MCS, and then quantizes the difference. (The quantization method can be equal interval quantization or unequal interval quantization)

[0315] Step 4: The terminal includes the quantized reference MCS transmission error probability, the quantized difference, the reference MCS identifier, and the identifiers of the remaining MSCs, or includes the quantized reference MCS transmission error probability and the quantized difference (assuming that the MCS identifier is already included in the first channel information) in the UCI, carries it in the PUCCH or PUSCH, and sends it to the network.

[0316] In some embodiments, the step of sorting the MCS levels based on maximizing the effective transmission rate may include sorting the MCS levels according to the following formula:

[0317] Among them, Rl is the transmission rate or spectrum efficiency corresponding to MCS level l, p NACK,l is the transmission error probability corresponding to MCS level l; R l (1-p NACK,l ) is the effective transmission rate corresponding to MCS level l, l * Indicates maximizing the effective transmission rate.

[0318] In some embodiments of the present application, the method 200 further includes:

[0319] The terminal receives at least one candidate information, where each candidate information corresponds to at least one transmission configuration, and the at least one candidate information includes the first information.

[0320] Optionally, in a case where the at least one candidate information includes one candidate information, the terminal may process the second information based on the one candidate information, that is, the one candidate information is the first information.

[0321] Optionally, when the at least one candidate information includes multiple candidate information, the terminal may select one of the multiple candidate information as the target information for processing the second information, or the terminal may select the target information based on the instruction of the network-side device. For example, the network-side device may send an eleventh indication to the terminal, and the eleventh indication is used to indicate the target information among the multiple candidate information. Optionally, the eleventh indication may explicitly or implicitly indicate the target information. For example, each candidate information among the multiple candidate information corresponds to an index or identifier, and the eleventh indication may be used to indicate the index or identifier corresponding to the target information, or may also explicitly indicate the specific content included in the target information.

[0322] Optionally, different transmission configurations may correspond to different transmission accuracy requirements, or different transmission configurations may correspond to different source similarity requirements, or different transmission configurations may correspond to different processing complexities, or different transmission configurations may correspond to different transmission overheads, or different transmission configurations may correspond to different levels (e.g., different quantization levels) of channel information provided to the network side device. Thus, the network side device may flexibly select an appropriate transmission configuration to process the second information based on the specific scenario to meet the requirements of the scenario. Alternatively, the terminal may also request the desired transmission configuration from the network based on the specific scenario to meet the requirements of the scenario.

[0323] In some embodiments of the present application, the method 200 further includes:

[0324] The terminal receives sixth information from the network-side device, where the sixth information is used to trigger the terminal to send third information, for example, trigger the terminal to send the third information based on the first information.

[0325] That is, the terminal may send the third information to the terminal based on the triggering of the network side device.

[0326] In other embodiments, the terminal may also trigger itself to send the third information to the network-side device, which is not limited in this application.

[0327] In some embodiments, the sixth information may include an eleventh indication, that is, when the network side device triggers the terminal to send the third information, it also indicates the transmission configuration of the channel information, that is, which information is used to process the channel information to obtain the third information.

[0328] Optionally, the sixth information may include an eleventh indication for indicating a transmission configuration, or may include multiple eleventh indications for indicating multiple transmission configurations, that is, the network side device can configure one or more transmission configurations for the terminal, and the terminal can determine that the first information includes one or more transmission configurations based on the sixth information.

[0329] In some embodiments of the present application, the method 200 further includes:

[0330] The terminal sends seventh information to the network side device, and the seventh information is used to request that the third information be sent to the network side device, or to request that the third information be sent to the network side device based on the first information, or to request the network side device to configure the target information among multiple candidate information for the terminal.

[0331] For example, when receiving the seventh information from the terminal, the network side device sends the sixth information to the terminal, triggering the terminal to send the third information.

[0332] That is, the network side device triggering the terminal to send the third information may be based on the terminal's request, or may be decided by the network side device itself, and this application does not limit this.

[0333] In some embodiments, the seventh information includes a twelfth indication, and the twelfth indication can be used to indicate a transmission configuration desired by the terminal, that is, to indicate the candidate information based on which the terminal desires to obtain the third information.

[0334] Optionally, the seventh information may include a twelfth indication for indicating a transmission configuration, or may include multiple twelfth indications for indicating multiple transmission configurations, that is, the terminal may request one or more transmission configurations from the network side device.

[0335] Optionally, the twelfth indication may explicitly or implicitly indicate the candidate information (or transmission configuration) that the terminal expects to use, for example, indicating the index or identifier of the expected candidate information.

[0336] In some embodiments, the third information may include a thirteenth indication, which is used to indicate which candidate information (or transmission configuration) the third information is processed based on, so that the network side device can perform corresponding processing on the third information based on the candidate information (or transmission configuration), thereby ensuring the correspondence between network side processing and terminal side processing, and ensuring the accuracy of transmission recovery.

[0337] In some embodiments, the third information may include one or more thirteenth indications, used to instruct the terminal to obtain one or more transmission configurations used by the third information.

[0338] Optionally, the thirteenth indication may explicitly or implicitly indicate the first information. For example, the thirteenth indication may indicate the same content as the eleventh indication, for example, indicating an index or identifier corresponding to the first information, or may also indicate specific content included in the first information, which is not limited in this application.

If the first information also includes multiple eighth indications, the corresponding multiple second operations are also activated.

[0375] Embodiment 3: Semi-persistent configuration or aperiodic configuration based on terminal request.

[0376] The information transmission method may include the following steps:

[0383] Optionally, in some embodiments, the seventh information includes a twelfth indication, that is, the twelfth indication in the seventh information indicates a transmission configuration or a transmission processing operation.

[0384] Then, in step S302, the terminal requests a transmission configuration or transmission processing operation corresponding to a twelfth indication.

[0388] In step 303, the network-side device triggers transmission configurations or transmission processing operations corresponding to multiple eleventh indications. The first information may include the transmission configurations corresponding to the multiple eleventh indications. For example, if the first information includes multiple first indications, the first operation corresponding to each first indication is activated. If the first information includes multiple eighth indications, the transmission configuration or processing operation corresponding to each second indication is activated.

[0389] In summary, in an embodiment of the present application, the terminal can obtain first information, which is used to indicate the transmission configuration of the channel information, including the configuration of the processing method of the channel information, the verification method configuration, the model-related configuration, etc., and then process the second information according to the first information, wherein the second information includes the first channel information, and further send the third information to the network side device. Correspondingly, the network side device can recover the channel information based on the third information. Since the third information is obtained by processing the second information based on the first information, compared with directly sending the second information to the network side device, when the network side obtains the same richness of channels, the transmission overhead can be greatly reduced; or compared with the case where the network side sends the third information with the same transmission overhead, richer channel information can be provided to the network side device. In this way, the network side device can allocate an MCS or precoding information that better matches the channel to the terminal based on the channel information or select a more suitable user for scheduling, thereby improving the throughput of the system.
