Alternatively, the channel information may also be a CSI report. Alternatively, the channel information may also be time domain information, frequency domain information, time-frequency domain information, or channel information in the delay-doppler domain, etc., and there is no specific limitation on this.

Among them, in this application, channel information can be divided into known channel information and unknown channel information. Known channel information and unknown channel information are relative to whether the channel information has been determined. The channel information that has been determined is known channel information, and the channel information that has not yet been determined is unknown channel information. For example, known channel information can be understood as previous channel information or historical channel information, and unknown channel information can be understood as current channel information and/or future channel information. For another example, known channel information can be understood as previous channel information and/or current channel information, and unknown channel information can be understood as future channel information. It should be noted that in this application, the current channel information can also be described as current channel information, current channel information, or current channel information, etc.

In some embodiments, the previous channel information, current channel information, and future channel information may be measurement resources associated with the relative indication information (such as CSI-RS resources and/or channel state information interference measurement (CSI-RS)). IM) resources, etc.) in terms of the reception time. This indication information is sent by the network side to the terminal device and can indicate the associated measurement resources. Optionally, the reception time of the measurement resources associated with the indication information may be earlier than or equal to the reception time of the indication information. For example, the channel information determined before the reception time of the measurement resources associated with the indication information is the previous channel information; according to the indication information The channel information determined by the associated measurement resources is the current channel information; in The channel information for a certain period of time after the reception time of the measurement resources associated with the indication information (which may or may not include the reception time of the measurement resources associated with the indication information) is future channel information. Optionally, the reception time of the measurement resources associated with the indication information may be later than the reception time of the indication information. For example, the channel information determined before the reception time of the measurement resources associated with the indication information is the previous channel information; The channel information determined by the measurement resources (such as measured or predicted) is the current channel information; a certain period of time after the reception time of the measurement resources associated with the indication information (which may or may not include the measurement resources associated with the indication information) The channel information at the reception time is the future channel information. The measurement resources associated with the indication information may be configured in the configuration information. For example, the configuration information may be CSI measurement configuration (CSI-MeasConfig) information, CSI report configuration (CSI-ReportConfig) information, or CSI resources. Configuration information (i.e. CSI-ResourceConfig). The reception time of the measurement resource can be understood as the reception time of the measurement resource, or the time unit of receiving the measurement resource, or the basic time unit of receiving the measurement resource, etc.

In other embodiments, the previous channel information, current channel information, and future channel information may be relative to the time at which the measurement resource associated with the indication information is located.

It can also be understood as the measurement resource. The occupied time domain resources may be, for example, the time unit in which the resource occupancy is measured, or the basic time unit in which the resource occupancy is measured, etc. The time unit at which the measurement resource is located takes the time unit occupied by the measurement resource as an example. The time unit occupied by the measurement resource associated with the indication information may be earlier than, equal to, or later than the time unit at which the indication information is received. For example, the channel information determined before the time unit occupied by the measurement resources associated with the indication information is the previous channel information; the channel information determined based on the measurement resources associated with the indication information is the current channel information; the measurement resources associated with the indication information are the current channel information. The channel information for a certain period of time after the occupied time unit is the future channel information. For example, taking the time unit as a time slot, assume that the time unit at which the indication information is received is time slot 3 (that is, the index number of the slot is 3), and the time slot occupied by the measurement resource associated with the indication information is time slot 4. Then the channel information determined in and before time slot 3 is the previous channel information, and the channel information determined based on the measurement resources associated with the indication information is the current channel information. During the period from time slot 5 to time slot 7 The channel information within is the future channel information.

The same information or different information can be sent through different beams. It can be understood that the beam may be carried or characterized by a reference signal.

The beam information that has been determined is known beam information, and the beam information that has not yet been determined is unknown beam information. For example, known beam information can be understood as previous beam information or historical beam information, and unknown beam information can be understood as current beam information and/or future beam information. For another example, known beam information can be understood as previous beam information and/or current beam information, and unknown beam information can be understood as future beam information. It should be noted that in this application, the current wave Beam information can also be described as current beam information, current beam information, or current beam information, etc.

In some embodiments, the previous beam information, current beam information, and future beam information may be relative to the reception time of the measurement resources (such as CSI-RS resources and/or CSI-IM resources, etc.) associated with the indication information. This indication information is sent by the network side to the terminal device and can indicate the associated measurement resources. Optionally, the reception time of the measurement resources associated with the indication information may be earlier than or equal to the reception time of the indication information. For example, the beam information determined before the reception time of the measurement resources associated with the indication information is the previous beam information; according to the indication information The beam information determined by the associated measurement resources is the current beam information; the beam information for a certain period of time after the reception time of the measurement resources associated with the indication information (which may or may not include the reception time of the measurement resources associated with the indication information) is for future beam information. Optionally, the reception time of the measurement resources associated with the indication information may be later than the reception time of the indication information. For example, the beam information determined before the reception time of the measurement resources associated with the indication information is the previous beam information; The beam information determined by the measurement resources (such as measured or predicted) is the current beam information; a certain period of time after the reception time of the measurement resources associated with the indication information (which may or may not include the measurement resources associated with the indication information) The beam information at the reception time is the future beam information. The measurement resources associated with the indication information may be configured in the configuration information. For example, the configuration information may be CSI-MeasConfig, CSI report configuration information (i.e., CSI-ReportConfig), or CSI resource configuration information (i.e., CSI -ResourceConfig). The reception time of the measurement resource can be understood as the reception time of the measurement resource, or the time unit of receiving the measurement resource, or the basic time unit of receiving the measurement resource, etc.

In other embodiments, the previous beam information, current beam information, and future beam information may be relative to the time at which the measurement resource associated with the indication information is located. The moment when the measurement resource is located can be understood as the time or the time unit or the basic time unit where the measurement resource is located. It can also be understood as the time domain resource occupied by the measurement resource. For example, it can be the time unit occupied by the measurement resource, or The basic time unit for measuring resource occupation, etc. The time unit at which the measurement resource is located takes the time unit occupied by the measurement resource as an example. The time unit occupied by the measurement resource associated with the indication information may be earlier than, equal to, or later than the time unit at which the indication information is received. For example, the beam information determined before the time unit occupied by the measurement resources associated with the indication information is the previous beam information; the beam information determined based on the measurement resources associated with the indication information is the current beam information; the measurement resources associated with the indication information are the current beam information. The beam information for a certain period of time after the occupied time unit is the future beam information. For example, taking the time unit as a time slot, assume that the time unit at which the indication information is received is time slot 3 (that is, the index number of the slot is 3), and the time slot occupied by the measurement resource associated with the indication information is time slot 4. Then the beam information determined in time slot 3 and before is the previous beam information, and the beam information determined according to the measurement resources associated with the indication information is the current beam information. During the period from time slot 5 to time slot 7 The beam information within is the future beam information.

4. In this application, terminal equipment and network equipment can deploy artificial intelligence (AI) models or algorithms. AI models are a type of mathematical algorithm model that uses machine learning ideas to solve practical problems. The AI model can include a large number of parameters and calculation formulas (or calculation rules). The parameters in the AI model are values that can be obtained by training the AI model through the training data set. For example, if the AI model is used to compress or decompress or predict channel information, the training data set may include one or more channel information, for example. If the AI model is used to predict beam information, the training data set may include one or more beam information, for example. In a possible implementation, the AI model deployed in the terminal device can be used to compress channel information, predict channel information, predict beam information, etc., and the AI model deployed in the network device can be used to decompress channel information, etc. It should be understood that terminal devices and network devices can deploy one or more AI models, and different AI Models function differently.

In a communication system, generally the network device sends configuration information for obtaining CSI to the terminal device, so that the terminal device passively obtains the channel state information according to the configuration information. In this way, the terminal equipment has poor mobility. To solve this problem, please refer to Figure 2, which is a schematic flowchart of a communication method provided by an embodiment of the present application. As shown in Figure 2, the communication method includes the following steps 201 to 203. The method execution subject shown in Figure 2 can be a terminal device and a network device. Alternatively, the method execution body shown in Figure 2 may be a chip in the terminal device and a chip in the network device. Figure 2 takes terminal equipment and network equipment as execution subjects of the method as an example for illustration.

201. The terminal device obtains the first information, and the first information instructs the terminal device to obtain the first CSI report.

Optionally, step 201 may include: the terminal device receives the first information from the network device, and accordingly, the network device sends the first information to the terminal device.

In a possible implementation, the first information is carried in downlink control information (DCI) or media access control (media access control, MAC) signaling. In another possible implementation, the first information is carried in CSI-MeasConfig information.

Wherein, the first CSI report may include the first CSI.

In the first case (denoted as case 1), the first CSI indicates second channel information obtained by compressing the first channel information, and the first channel information is determined based on the reference signal from the network device. It can be understood that the terminal device can receive the reference signal from the network device to perform channel estimation based on the reference signal to obtain the first channel information. Then, the terminal device can compress the first channel information to obtain the second channel information. For example, the terminal device can use AI model 1 compresses the first channel information to obtain the second channel information. Finally, the terminal device may generate the first CSI according to the second channel information, that is, the first CSI may indicate the second channel information compressed according to the first channel information. When the network device obtains the first CSI, it can obtain the second channel information according to the first CSI indication, and decompress the second channel information to obtain the first channel information. For example, the network device can use AI model 2 to calculate the second channel information. The information is decompressed to obtain the first channel information. It can be seen that because the first CSI indicates the second channel information obtained by compressing the first channel information, resource overhead can be reduced, and the network device can also obtain high-precision channel information.

In the second case (denoted case 2), the first CSI indicates third channel information obtained based on the first channel information. Wherein, the first CSI indicates the third channel information obtained based on the first channel information, which can be understood as: the first CSI indicates the third channel information predicted based on the first channel information. For example, the terminal device can input the first channel information into the AI Model 3 predicts and obtains the third channel information.

For example, the first channel information may be previous channel information, and the terminal device may predict current channel information or future channel information (ie, third channel information) based on the previous channel information. For example, the terminal device may use the previous channel information to Input AI model 3 for prediction to obtain the current channel information or future channel information (ie, the third channel information).

As another example, the first channel information can be the current channel information, and the terminal device can predict future channel information (ie, the third channel information) based on the current channel information. For example, the terminal device can input the current channel information into the AI model 3 Prediction is made to obtain future channel information (ie, third channel information).

As another example, the first channel information may include previous channel information and current channel information. The terminal device may predict future channel information (ie, third channel information) based on the previous channel information and current channel information. For example, the terminal device The previous channel information and the current channel information can be input into the AI model 3 for prediction to obtain the future channel information. information (i.e. third channel information).

It should be understood that after the terminal device obtains the third channel information, the terminal device may generate the first CSI according to the third channel information, that is, the first CSI may indicate the third channel information obtained according to the first channel information. In the case where the network device obtains the first CSI, the third channel information may be obtained according to the first CSI indication. It can be seen that because the first CSI indicates the third channel information obtained based on the first channel information, the problem that the terminal equipment needs to perform measurement and channel estimation to obtain the third channel information is avoided.

In the third case (denoted case three), the first CSI indicates second beam information obtained based on the first beam information.

In a possible implementation, the first CSI indicates the second beam information obtained based on the first beam information, which can be understood as: the first CSI indicates the second beam information predicted based on the first beam information. For example, the terminal device uses the second beam information predicted based on the first beam information. The first beam information is input to the AI model 4 for prediction, and the second beam information is obtained. For example, the first beam information may be the previous beam information, and the terminal device may predict the current beam information or the future beam information (ie, the second beam information) based on the previous beam information. For example, the terminal device may use the previous beam information. Input AI model 4 for prediction to obtain the current beam information or future beam information (i.e., the second beam information). As another example, the first beam information can be the current beam information, and the terminal device can predict future beam information (ie, the second beam information) based on the current beam information. For example, the terminal device can input the current beam information into the AI model 4 Prediction is made to obtain future beam information (ie, second beam information). As another example, the first beam information may include previous beam information and current beam information, and the terminal device may predict future beam information (ie, second beam information) based on the previous beam information and current beam information, such as the terminal device The previous beam information and the current beam information can be input into the AI model 4 for prediction to obtain future beam information (ie, the second beam information).

In another possible implementation, the first beam information can be understood as partial beam information, and the second beam information can be understood as other beam information and/or partial beam information except the partial beam information. That is, the terminal device can obtain other beam information and/or partial beam information based on the partial beam information. For example, the terminal device can input partial beam information into the AI model 4 to obtain other beam information and/or partial beam information.

It can be seen that because the first CSI indicates the second beam information obtained based on the first beam information, the problem that the terminal equipment needs to receive the reference signal and then determine the second beam information is avoided.

Optionally, the number of first CSIs may be one or more. In a possible implementation, a first CSI may indicate any one or more of the above situations one to three. In another possible implementation, multiple first CSIs may indicate the above situations one to three, and different CSIs may indicate different information. For example, CSI1 indicates case one, CSI2 indicates case two, and CSI3 indicates case three. In another possible implementation, multiple first CSIs may indicate the above situations one to three, and the information indicated by different CSIs is the same. For example, both CSI1 and CSI2 indicate situation one.

202. The terminal device obtains the second CSI report based on the first information.

The second CSI report may include the second CSI.

In the first case (denoted as case 1), the second CSI indicates second channel information obtained by compression according to the first channel information, and the first channel information is determined according to the reference signal from the network device. It can be understood that the terminal device can receive the reference signal from the network device to perform channel estimation based on the reference signal to obtain the first channel information. Then, the terminal device can compress the first channel information to obtain the second channel information. For example, the terminal device can use AI model 1 versus first The channel information is compressed to obtain second channel information. Finally, the terminal device may generate the second CSI according to the second channel information, that is, the second CSI may indicate the second channel information compressed according to the first channel information. When the network device obtains the second CSI, it can obtain the second channel information according to the second CSI indication, and decompress the second channel information to obtain the first channel information. For example, the network device can use AI model 2 to obtain the second channel information. The information is decompressed to obtain the first channel information. It can be seen that because the second CSI indicates the second channel information obtained by compressing the first channel information, resource overhead can be reduced, and the network device can also obtain high-precision channel information.

In the second case (denoted case 2), the second CSI indicates third channel information obtained based on the first channel information. Wherein, the second CSI indicates the third channel information obtained based on the first channel information, which can be understood as: the second CSI indicates the third channel information predicted based on the first channel information. For example, the terminal device can input the first channel information into the AI Model 3 predicts and obtains the third channel information.

As another example, the first channel information may include previous channel information and current channel information. The terminal device may predict future channel information (ie, third channel information) based on the previous channel information and current channel information. For example, the terminal device The previous channel information and the current channel information can be input into the AI model 3 for prediction to obtain future channel information (ie, the third channel information).

It should be understood that after the terminal device obtains the third channel information, the terminal device may generate the second CSI according to the third channel information, that is, the second CSI may indicate the third channel information obtained according to the first channel information. In the case where the network device obtains the second CSI, the third channel information may be obtained according to the second CSI indication. It can be seen that because the second CSI indicates the third channel information obtained based on the first channel information, the problem that the terminal equipment needs to perform measurement and channel estimation to obtain the third channel information is avoided.

In the third case (denoted case 3), the second CSI indicates second beam information obtained based on the first beam information.

In a possible implementation, the second CSI indicates the second beam information obtained according to the first beam information, which can be understood as: the second CSI indicates the second beam information predicted according to the first beam information. For example, the terminal device uses the second beam information predicted according to the first beam information. The first beam information is input to the AI model 4 for prediction, and the second beam information is obtained. For example, the first beam information may be the previous beam information, and the terminal device may predict the current beam information or the future beam information (ie, the second beam information) based on the previous beam information. For example, the terminal device may use the previous beam information. Input AI model 4 for prediction to obtain the current beam information or future beam information (i.e., the second beam information). As another example, the first beam information can be the current beam information, and the terminal device can predict future beam information (ie, the second beam information) based on the current beam information. For example, the terminal device can input the current beam information into the AI model 4 Prediction is made to obtain future beam information (ie, second beam information). As another example, the first beam information may include previous beam information and current beam information, and the terminal device may predict future beam information (ie, second beam information) based on the previous beam information and current beam information, such as the terminal device The previous beam information and the current beam information can be input into the AI model 4 for prediction to obtain the future wave information. Beam information (i.e. second beam information).

It can be seen that because the second CSI indicates the second beam information obtained based on the first beam information, the problem that the terminal equipment needs to receive the reference signal to determine the second beam information is avoided.

In the fourth case (denoted case 4), the second CSI indicates the first channel information. It can be understood that the terminal device can receive a reference signal from the network device to perform channel estimation based on the reference signal to obtain the first channel information. After the terminal device obtains the first channel information, the terminal device may generate the second CSI according to the first channel information, that is, the second CSI may indicate the first channel information. In the case where the network device obtains the second CSI, the first channel information may be obtained according to the second CSI indication. It can be seen that because the second CSI indicates the first channel information, and the first channel information is obtained by the terminal device performing channel estimation based on the reference signal, it indicates that the terminal device independently decides to obtain the channel state information, which improves the initiative of the terminal device. It also improves the flexibility of terminal equipment in obtaining channel status information.

Optionally, the number of second CSIs may be one or more. In a possible implementation, a second CSI may indicate any one or more of the above situations 1 to 4. In another possible implementation, multiple second CSIs may indicate the above situations 1 to 4, and different CSIs may indicate different information. For example, CSI1 indicates case 1, CSI2 indicates case 2, CSI3 indicates case 3, and CSI4 indicates case 4. In another possible implementation, multiple second CSIs may indicate the above situations 1 to 4, and the information indicated by different CSIs may be the same. Illustratively, both CSI1 and CSI2 indicate case 1.

Optionally, the information indicated by the first CSI and the second CSI may be partially or completely the same or completely different, which is not limited here.

Optionally, the second CSI report may also include second information, and the second information indicates the CSI included in the second CSI report. In a possible implementation, part 1 of the second CSI report may include second information. In a possible implementation, the second information indicates that the CSI included in the second CSI report corresponds to the above-mentioned first situation, the above-mentioned second situation, the above-mentioned third situation, or the above-mentioned fourth situation.

203. The network device receives the second CSI report.

Correspondingly, the terminal device sends a CSI report.

Wherein, step 203 may include: the network device receives the second CSI report from the terminal device. Correspondingly, the terminal device sends the second CSI report to the network device.

It can be seen that when the terminal device obtains the first information, because the first information instructs the terminal device to obtain the first CSI report, and the terminal device can obtain the second CSI report based on the first information, it indicates that the terminal device can independently decide on CSI The acquisition improves the initiative of the terminal equipment and also improves the flexibility of the terminal equipment in obtaining CSI.

In a communication system, the network device generally sends the configuration information for obtaining the CSI to the terminal device, so that the terminal device will obtain the CSI according to the configuration information. When the accuracy of CSI is too low, CSI related processing can generally be implemented through radio resource control (RRC) reconfiguration messages. However, this method may cause high energy consumption of the terminal equipment. In order to solve this problem, please refer to Figure 3. Figure 3 is another communication provided by the embodiment of the present application. Flow diagram of the method. As shown in Figure 3, the communication method includes the following steps 301. The method execution subject shown in Figure 3 may be a terminal device. Alternatively, the method execution subject shown in Figure 3 may be a chip in the terminal device. Figure 3 takes the terminal device as the execution subject of the method as an example for illustration.

301. The terminal device obtains the first information, and determines whether to obtain the first CSI report based on the first information.

Optionally, the terminal device obtains the first information, which may include: the terminal device receives the first information from the network device, and accordingly, the network device sends the first information to the terminal device.

Optionally, the terminal device determines whether to obtain the first CSI report based on the first information, including: if the first information indicates that the terminal device does not obtain the first CSI report, the terminal device does not obtain or update the first CSI report; if the first information indicates that the terminal device does not obtain the first CSI report; The information instructs the terminal device to obtain the first CSI report, and the terminal device obtains (or reacquires) the first CSI report and sends the first CSI report.

The terminal device sending the first CSI report may include: the terminal device sending the first CSI report to the network device, and correspondingly, the network device receiving the first CSI report from the terminal device.

It can be seen that when the first information instructs the terminal device not to obtain the first channel status information report, the terminal device may not obtain or update the first channel status information report, thereby dynamically enabling the acquisition of the channel status information report. ; In the case where the first information instructs the terminal device to obtain the first channel status information report, the terminal device can obtain the first channel status information report, thereby dynamically enabling the acquisition of the channel status information report, which avoids the accuracy of CSI When it is too low, you need to use RRC reconfiguration messages to enable or disable CSI measurement and reporting, which will cause the terminal device to consume too much energy. It also saves the time to enable or disable CSI measurement and reporting.

Optionally, the first information is carried in DCI or MAC signaling.

Wherein, the first CSI report may include the first CSI. Regarding the first CSI, reference may be made to the relevant description of step 201 in Figure 2, which will not be described again here.

It can be seen that when the terminal device obtains the first information, the terminal device can determine whether to obtain the first CSI report based on the first information, thereby dynamically enabling or disabling the acquisition of the CSI report, and avoiding CSI When the accuracy is too low, RRC reconfiguration messages need to be used to enable or disable CSI, which may cause excessive energy consumption of the terminal device. This also saves time in enabling or disabling CSI.
