The precoding information may include the precoding itself or the quantization value corresponding to the precoding, various sub-band or broadband precoding matrix identifiers PMI, etc.

[0042] In some examples, the channel information is information obtained based on a reference signal (such as CSI-RS) for describing the channel environment between communication nodes. In some examples, the channel information is a complex matrix, which can be called a channel matrix. The size of the channel matrix is ​​related to the number of transmitting antennas Nt, the number of receiving antennas Nr, and resource elements.

[0047] In the embodiment of the present disclosure, transmitting CSI means transmitting CSI (or channel state information) on uplink transmission resources. In one example, transmitting a CSI report means transmitting the content indicated in the CSI report, such as CSI, etc., where transmitting includes sending or receiving.

[0049] Multi-antenna technology, as a key technical means to improve the spectrum efficiency of wireless communications, is widely used in various wireless communication systems, and its performance optimization is inseparable from accurate CSI. Channel state information can be obtained through a variety of information processing methods, such as artificial intelligence (AI) based on different models, by decomposing eigenvalues ​​or singular values, and based on codebooks. Among them, multi-antenna technology includes multiple input multiple output (MIMO), joint transmission of multiple transmission nodes (JT), high-frequency beamforming, etc.

[0050] In this regard, the embodiment of the present disclosure provides a channel state information transmission method, which determines a target information processing method from N information processing methods, and obtains CSI according to the target information processing method; generates a first CSI report according to the target information processing method and the CSI; and sends the first CSI report so that the second node can obtain the CSI and the information processing method corresponding to the CSI based on the first CSI report. The first node can select an appropriate target information processing method from the N information processing methods based on the current scenario or current demand, thereby improving the accuracy of the channel state information.

[0051] In addition, for the downlink, generally speaking, the channel changes with the environment and the movement of the terminal. Different information processing methods may correspond to different channels. The terminal can obtain the downlink channel information, so that it can select the appropriate information processing method to obtain CSI, so as to better match the current channel. In this way, selecting the appropriate information processing method according to the different channels to obtain channel state information helps to provide the accuracy of CSI.

The communication network in the embodiment of the present disclosure includes but is not limited to the third generation mobile communication technology (3G), the fourth generation mobile communication technology (4G), the fifth generation mobile communication technology (5G) and future mobile communication networks, such as 6G, 7G, etc. The network architecture may include network side devices (for example, including but not limited to base stations) and receiving side devices (for example, including but not limited to terminals).

In the device-to-device communication between the two communication nodes, the first communication node and the second communication node may both be base stations or terminals. The first communication node and the second communication node may be referred to as the first node and the second node, respectively. In other embodiments, the first node and the second node need to be determined according to the semantic environment.

[0053] For example, the network side device is a base station and the receiving side device is a terminal. Figure 1 FIG. 1 is a schematic diagram showing an architecture of a communication system provided by an embodiment of the present disclosure.

[0055] In some embodiments, the first node 101 determines a target information processing mode from N information processing modes, and obtains CSI according to the target information processing mode. The first node 101 generates a first CSI report according to the target information processing mode and the CSI, and sends the first CSI report so that the second node 102 can obtain the CSI and the information processing mode corresponding to the CSI based on the first CSI report. In this way, the first node 101 can select an appropriate target information processing mode from multiple information processing modes based on the current scenario or current demand, thereby improving the accuracy of the channel state information.

[0075] In the case of acquiring N information processing modes based on the received first signaling and a predefined method, the manner of acquiring the N information processing modes includes:

[0076] M information processing methods are acquired based on the first signaling, and N information processing methods are determined from the M information processing methods based on a predefined method, where M is greater than or equal to N.

[0077] Among them, the predefined method includes: when the capacity of the transmission resource corresponding to the first CSI report (for example, the transmission resource carrying the first CSI report) is greater than or equal to the first preset threshold value, M information processing methods are determined to be N information processing methods, where M is equal to N.

[0078] The predefined manner includes: when the capacity of the transmission resource corresponding to the first CSI report is less than the second preset threshold value, the N information processing manners include one of the following:

[0079] An information processing method in which the index value is less than the first preset index value among the M information processing methods.

[0080] An information processing method in which the index value is greater than the second preset index value among the M information processing methods.

[0081] The information processing method with an odd index value among the M information processing methods.

[0082] The information processing method with an even index value among the M information processing methods.

[0083] Since the capacity of the transmission resource corresponding to the first CSI report indicates the ability to transmit CSI, when the CSI obtained based on the information processing method is large, more transmission resources are required to transmit the first CSI report. However, the size of the CSI obtained based on different information processing methods is different. Therefore, when the capacity of the transmission resource carrying the first CSI report is large, the first node has more types of information processing methods to choose from. In this way, based on the capacity of the transmission resource, a variety of information processing methods that are more suitable for the capacity size can be determined, otherwise only the information processing method that matches the transmission bit corresponding to the CSI and the capacity of the transmission resource can be selected. Optionally, the first preset threshold value and the second preset threshold value may be the same or different.

[0084] In some embodiments, the capacity of the transmission resource includes one of the following: the number of REs corresponding to the transmission resource; the number of modulation symbols that the transmission resource can transmit; the number of effective modulation symbols that the transmission resource can transmit; the number of bits that the transmission resource can transmit; the number of effective bits that the transmission resource can transmit; wherein the number of effective modulation symbols is the number of modulation symbols corresponding to the information source transmitted by the transmission resource. The number of effective bits that the transmission resource can transmit refers to the number of bits corresponding to the information source transmitted by the transmission resource after quantization. That is, it does not include bits such as channel coding, CRC, and rate matching.

[0085] In some embodiments, the first node obtains channel information according to the received reference signal. After the first node obtains N information processing modes, the channel information is processed according to the N information processing modes to obtain N channel state information. N performance indicators are calculated according to the N channel state information and the channel information, and K information processing modes whose performance indicators meet the preset requirements are selected as target information processing modes. K and N are positive integers, and K is less than or equal to N. Optionally, K=1.

[0086] In one example, the performance indicator is the correlation between the channel state information (e.g., precoding matrix) and the channel matrix, cosine similarity (CS), squared generalized cosine similarity (SGCS), etc. The performance indicator that meets the preset requirements includes but is not limited to at least one of the following: K performance indicators with the largest values ​​among N performance indicators, or K performance indicators among N performance indicators whose performance indicators are greater than or equal to a first preset indicator threshold, where the first preset threshold is a real number.

[0087] In one example, the performance indicator is the distance between the channel state information (e.g., a precoding matrix) and the channel matrix, or the norm, mean square error (MSE), normalized mean square error (NMSE), etc. of the difference between the precoding matrix and the channel matrix. The performance indicator meets the preset requirements including but not limited to at least one of the following: K performance indicators with the smallest values ​​among N performance indicators, and K performance indicators among N performance indicators that are less than or equal to a second preset indicator threshold.

[0088] The above is a description of determining N information processing methods. The following describes the first CSI report.

[0089] In some embodiments, the first CSI report includes at least a first part of a CSI report, the first part of the CSI report includes at least a first field, and the first field is used to indicate parameters of a target information processing method.

[0090] The parameter of the target information processing method includes at least one of the following: an index of the target information processing method, and a resource index corresponding to the target information processing method. The resource index includes at least one of the following: a model index corresponding to the target information processing method, a function index corresponding to the target information processing method, a reference signal index corresponding to the target information processing method, a beam index corresponding to the target information processing method, and an auxiliary index (associated ID) corresponding to the target information processing method.

[0091] For example, the first field is used to indicate the target information processing method or the index of the target information processing method. For example, K information processing methods are selected from N information processing methods as the target information processing methods. The first field indicates the indexes of K information processing methods (information processing method indicator, IPMI). K and N are positive integers, and K is less than or equal to N.

[0092] It should be pointed out that the index of the target information processing method indicated by the first field can be replaced by the function identifier corresponding to the target information processing method and the model identifier corresponding to the target information processing method, which will not be described in detail below.

[0093] In some embodiments, the first field includes C bits, where C bits are used to indicate parameters (e.g., indexes) of the target information processing method, and C is a positive integer of ceil(log2(N)). ceil() is the rounding of a number. Log2() is the logarithm of a number with a base of 2.

[0094] In some embodiments, the first field includes N bits, the N bits correspond to N information processing methods, and the value of the i-th bit in the N bits is used to indicate whether the i-th information processing method is the target information processing method, that is, the value of one bit is used to indicate whether the information processing method corresponding to the bit is the target information processing method. For example, when the i-th bit takes the first value, it indicates that the i-th information processing method is the target information processing method, and when the i-th bit takes the second value, it indicates that the i-th information processing method is not the target information processing method. Here, the first value and the second value are two different values, which can be real numbers, Boolean values, integers, strings, etc., such as one is 1 and the other is 0, or one is TRUE and the other is FALSE, i=1,…,N.

[0095] In some embodiments, the first field includes D bits, and the D bits are used to indicate one row in the information processing mode table, and the information processing mode table includes at least one row, and each row includes a parameter combination of at least one information processing mode selected from N information processing modes. Take N=2, 3, 4 as an example, as shown in Table 1:

[0096] Table 1

[0097]

[0098]

[0099] Among them, Bit field mapped to index is a bit field mapped to the index, and IPMI is a combination of indexes of the information processing method.

[0100] It should be noted that in other embodiments, N may take other values, which are not listed here. In other embodiments, for a value of N, the number of rows of the table included may also be obtained through negotiation between the first node or the second node, and may be all or part of all possible combinations of at least one information processing method selected from the N information processing methods.

[0101] In some embodiments, the first part of the CSI report also includes a second field, and the second field is used to transmit the first part of the CSI content. The first part of the CSI content includes at least one of the following: broadband CQI, first channel state information, CRI, RI, LI, non-zero amplitude coefficient of each layer, non-zero amplitude coefficient indication of each layer, etc. The first channel state information is channel state information obtained based on the second type of information processing method, such as the first type of broadband precoding matrix indicator PMI (type IPMI) and the first type of subband precoding matrix indicator PMI. For example, the broadband indicator of the typeI codebook, or the typeI subband indicator, i1, i2, i11, i12, i13, i21, i22, etc., can also be various second type precoding matrix indicators other than type I.

[0102] Exemplarily, different CSIs in the first part of the CSI report are carried by independent fields. For example, at least one field from the fourth field to the eighth field is included, which is used to transmit the first part of the CSI content. The fourth field is used to indicate the broadband CQI. The fifth field is used to indicate the broadband type IPMI. The sixth field is used to indicate CRI. The seventh field is used to indicate RI. The eighth field is used to indicate LI. In other embodiments, the first part of the CSI content has other fields in addition to the first to eighth fields here, which are not listed one by one here. In other embodiments, the first part of the CSI report has only one or more of the first to eighth fields, which do not necessarily exist at the same time. In other embodiments, the above-mentioned various fields can also be replaced by a bit group, or a string of bits, or a row in a table. The first to eighth indications are used to distinguish different fields and are not used for sorting.

[0103] In some embodiments, the first CSI report also includes a second part of a CSI report, and the second part of the CSI report is used to transmit the second part of the CSI. Among them, the second part of the CSI includes at least one of the following: subband CQI, second channel state information. The second channel state information is the CSI obtained according to the first type of information processing method. In one embodiment, the second channel state information is a precoding matrix or a quantized value of the precoding matrix obtained according to AI. In one embodiment, the subband CQI here is obtained based on the precoding matrix included in or corresponding to the first channel state information, or based on the right singular vector or matrix of the correlation matrix of the channel matrix.

[0104] The second field of the first part of the CSI report in the first CSI report is used to transmit the first part of the CSI content, and the second part of the CSI report in the first CSI report is used to transmit the second part of the CSI content. In addition to the first field and the second field, the first part of the CSI report may also include a third field. The third field is used to indicate whether the first CSI report also includes the third part of the CSI report, and the third part of the CSI report is used to transmit the third part of the CSI content. The third part of the CSI content is the remaining content of the CSI except for the CSI transmitted by the first part of the CSI report and / or the second part of the CSI report.

[0105] In some embodiments, optionally, the first part of the CSI may be empty, and the third part of the CSI may be empty. In this case, the CSI includes that the first part may only include the first field and / or the third field, and the second part of the CSI report is used to transmit the entire content of the CSI.

[0106] In some embodiments, optionally, the first part of the CSI content may be empty, in which case the CSI including the first part may only include the first field and / or the third field, and the second part of the CSI report is used to transmit the second part of the CSI content, and the third part of the CSI report is used to transmit the third part of the CSI report.

[0107] In some embodiments, optionally, the content of the first part of the CSI is not empty, and the content of the third part of the CSI is not empty. In this case, the CSI includes that the first part may only include the first field and / or the third field, the content of the first part of the CSI, and the second part of the CSI report is used to transmit the content of the second part of the CSI, and the third part of the CSI report is used to transmit the content of the third part of the CSI.

[0108] In some embodiments, optionally, the content of the first part of the CSI is not empty, and the content of the third part of the CSI is not empty. In this case, the CSI includes the first part which may include the first field and / or the third field, the content of the first part of the CSI, and the second part of the CSI report is used to transmit the content of the second part of the CSI, and the third part of the content is transmitted using the second CSI report.

[0109] In some embodiments, when the third field is used to indicate that the first CSI report also includes the third part of the CSI report, the channel state information transmission method of the embodiment of the present disclosure also includes: receiving configuration information of the second CSI report; sending a second CSI report based on the configuration information, and the second CSI report is used to transmit the third part of the CSI content.

[0110] Although the first CSI report also includes the third part of the CSI report, the third part of the CSI report is carried in the second CSI report. For example, when the content of the CSI is large, the first CSI report cannot carry all the CSI, so the third part of the CSI is carried in the second CSI report. In this way, even if the transmission resources carrying the first CSI report are small, the first node can still transmit all the CSI to the second node, thereby ensuring the integrity of the CSI. Optionally, the transmission resources for transmitting the first CSI report and the second CSI report can meet different time domain resources and / or different frequency domain resources, such as transmission on different time slots, or transmission on different frequency domain resources in the same time slot.

[0111] It should be noted that the first node requests the second node to send the configuration information of the second CSI report through a high-layer signaling and / or a physical layer signaling, and the second node sends the configuration information of the second CSI report after receiving the request information. After receiving the configuration information, the first node transmits the third part of the CSI report through the second CSI report.

[0112] In some embodiments, the transmission time difference corresponding to the first CSI report and the second CSI report is less than the preset time difference. In the case where the transmission time difference corresponding to the first CSI report and the second CSI report is less than the preset time difference, the second CSI report is sent. In the case where the transmission time difference corresponding to the first CSI report and the second CSI report is greater than or equal to the preset time difference, the second CSI report is not sent. It should be understood that the transmission time difference is the difference between the transmission time points of the first CSI report and the second CSI report. After determining the transmission time point of the second CSI report, if it is determined that the transmission time difference between this transmission time and the transmission time of the first CSI report is less than the preset time difference, the second CSI report is not sent. It can also be understood that the transmission time point (or transmission time slot) of the first CSI report and the transmission time point of the second CSI report are both less than or equal to the preset time point. Among them, the transmission time difference includes time slot difference, sub-time slot difference, symbol difference, etc.

[0113] After receiving the second CSI report, the second node determines from the third field in the first CSI report that the third part of the CSI report is also included, and then continues to receive the second CSI report before the preset time point.

[0114] If the second node does not receive the second CSI report before the preset time point, the second CSI report is no longer received.

[0115] Alternatively, if the receiving time point of the first CSI report and the receiving time point of the second CSI report received by the second node are later than the preset time point, the second CSI report is discarded.

[0116] Alternatively, if the second node does not receive the second CSI report before the preset time point, or the difference between the reception time points of the first CSI report and the second CSI report is greater than the preset time difference, the first CSI report and the second CSI report are discarded.

[0117] In some embodiments, the first node obtains at least two types of channel state information according to at least two information processing methods. The at least two information processing methods include at least one first type of information processing method and at least one second type of information processing method. The at least two types of channel state information include at least one first type of channel state information and at least one second type of channel state information. The first node obtains a first type of channel state information and a second type of channel state information according to a first type of information processing method and a second type of information processing method, respectively.

[0118] In the case where the first node obtains a first type of channel state information and a second type of channel state information, the second type of channel state information includes at least one of the following: a broadband second type of precoding information, at least one broadband CQI, CRI, RI, LI. Among them, the broadband CQI is obtained based on the broadband second type of precoding information. RI is obtained based on the broadband CQI. CRI is obtained based on the broadband CQI and RI. LI is obtained according to the broadband CQI. The broadband second type of precoding information includes at least one of the following codebook indexes: type I codebook, type II codebook, type II port selection codebook, enhanced typeII codebook, enhanced type II selection codebook, Further enhanced type II selection codebook, Doppler codebook, joint transmission (CJT) codebook. Here, the first type of channel state information includes but is not limited to precoding information generated by nonlinear technologies such as artificial intelligence.

[0119] In some embodiments, in the second CSI report, the priority of the third part of the CSI content is greater than or equal to the priority of other content in the second CSI report except the third part of the content.

[0120] In some embodiments, the priority of the second CSI report including the third part of the CSI is greater than or equal to that of other CSI reports not including the third part of the CS in the same time slot.

[0121] In some embodiments, the first part of the CSI report and the second part of the CSI report are transmitted in different channels. For example, the first part of the CSI report is transmitted on a physical uplink control channel (PUCCH), and the second part of the CSI report is transmitted on a physical uplink shared channel (PUSCH). The first part of the CSI report and the second part of the CSI report are transmitted on different physical uplink shared channels, and they belong to transmission resources in different time slots or frequency domains.

[0122] In some embodiments, the CSI report first part and the CSI report second part are transmitted in the same channel.

[0123] In some embodiments, the first CSI report and the second CSI report correspond to the same CSI report configuration information, and the transmission time slots of the first CSI report and the second CSI report are different. The first part of the CSI report and the second part of the CSI report are transmitted on the transmission resources corresponding to the same CSI report, and the third part of the CSI report is transmitted on the transmission resources corresponding to another CSI report (e.g., the second CSI report).

[0124] In some embodiments, the first part of the CSI report, the second part of the CSI report, and the third part of the CSI report are transmitted on the same transmission resource corresponding to the CSI report, but the third part of the CSI report and the first part of the CSI report are transmitted in different time slots in the same transmission resource.

[0125] The channel state information transmission method provided by the embodiment of the present disclosure can be applied to Figure 1 A second node 102 is shown in the communication system. Figure 3 A schematic diagram of another channel state information transmission method is shown in FIG. Figure 3 As shown, the channel state information transmission method includes the following S301.

[0126] S301. The second node receives a first CSI report.

[0127] The first CSI report includes a target information processing method and CSI obtained based on the target information processing method. The target information processing method is selected from N information processing methods, where N is a positive integer greater than or equal to 1.

[0128] After the second node receives the first CSI report, it can determine the CSI and the target information processing method for generating the CSI based on the first CSI report. The first node can select the target information processing method from N information processing methods. In this way, the first node can select an adaptive target information processing method from multiple information processing methods based on the current scenario or current demand, thereby improving the accuracy of the channel state information. In addition, after the second node receives the first CSI report, it can determine the target information processing method based on the first CSI, and based on the information processing method on the second node corresponding to the target information processing method, such as a decoder, etc., it can select the corresponding decoder to process the obtained CSI to obtain the final CSI. Alternatively, the second node can determine whether the obtained CSI is the first type of precoding information or the second type of precoding information, or which type of second type of precoding, through the target information processing method. In some embodiments, the second type of precoding information can be used to monitor the information processing method corresponding to the first type of precoding information to monitor its performance.

[0129] In some embodiments, the second node needs to obtain a target information processing mode according to the received first CSI report, and knows which information processing mode the first node used to obtain the channel state information according to the obtained target information processing mode. In some embodiments, the second node will also process the obtained CSI accordingly to the obtained target information processing mode to obtain the final channel state information to improve the accuracy of the channel state information. In one example, the decoder corresponding to the target information processing mode is determined according to the target information processing mode to process the obtained CSI to obtain the final channel state information. In one example, the capability of the first node is determined according to the target information processing mode.

[0130] It should be pointed out that, for descriptions on determining the target information processing method, the CSI transmission method, etc., reference may be made to the description on the first node side, and the embodiments of the present disclosure will not be repeated here.

The above integrated modules may be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiments of the present disclosure is schematic and is only a logical function division. There may be other division methods in actual implementation. The following is an example of dividing each functional module corresponding to each function.
