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.

[0042] It should be noted that the data reporting solution provided in this application can be applied to the data collection function of AI-based CSI-related use cases in communication information systems with wireless AI functions such as 5.5G or 6G.

[0043] Based on this, the technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0044] like Figure 2a FIG. 2 is a flow chart of a data reporting method 200 provided in an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by a terminal, and specifically may be executed by at least one of hardware and software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0045] S210: The terminal obtains at least two CSI data.

[0046] In this embodiment, the terminal may acquire CSI data at a predetermined time interval, may acquire CSI data according to a received data acquisition instruction, or may receive CSI data from other terminals, etc., which is not limited here.

[0047] Based on this, after acquiring or collecting CSI data, the terminal may group the collected multiple CSI data according to characteristic information of the CSI data to obtain one or more first CSI data groups. For example, at least two CSI data with the same, similar, or related characteristic information may be grouped into the same CSI data group. That is, the characteristic information corresponding to each CSI data in the first CSI data group is the same, similar, or related. In this case, because the characteristic information corresponding to each CSI data in the first CSI data group is the same, similar, or related, each CSI data in the first CSI data group may correspond to the same description information. That is, the at least two CSI data included in the first CSI data group may be characterized using the same target description information.

[0048] It is worth noting that, compared to related technologies that report CSI data at the CSI data granularity, it is necessary to report characteristic description information (also referred to as description information) corresponding to each CSI data to describe the characteristic information of the CSI data, thereby resulting in problems such as high data overhead and low data reporting efficiency when reporting CSI data. In this embodiment, CSI data with identical, similar, or associated characteristic information are grouped and then the characteristic information corresponding to the CSI data is reported to the network-side device in the form of CSI data groups. In this way, for CSI data with identical, similar, or associated characteristic information, only description information, i.e., the target description information, needs to be reported once. The network-side device can then know the characteristic information of each CSI data included in the first CSI data group, eliminating the need to report the characteristic information of each CSI data separately for each CSI data report. This effectively reduces data overhead when reporting CSI data, avoids waste of network resources, and improves data reporting efficiency.

[0049] In this embodiment, one CSI data in one of the first CSI data groups may correspond to one moment (such as a data collection moment), that is, the first CSI data group may include CSI data of at least one moment.

[0050] S220: The terminal sends first information to the network side device.

[0051] Among them, the first information includes the target description information, and the target description information is used to describe characteristic information corresponding to the first CSI data group, such as the terminal characteristics of the first CSI data group, the data characteristics of each CSI data in the first CSI data group, etc., which are not limited here.

[0052] In an optional implementation, the terminal may have multiple transmission modes or sequences when sending the first CSI data group and the target description information to the network side device.

[0053] For example, Figure 2b As shown, the target description information may be sent before the first CSI data group.

[0054] For example, Figure 2c As shown, the target description information can be sent after the first CSI data group is sent.

[0055] For example, Figure 2d As shown, the target description information may be reported together with the first CSI data in the first CSI data group when it is sent, such as by placing the target description information after the first CSI data or transmitting the first CSI data in a special format.

[0056] For example, Figure 2e As shown, when the last CSI data in the first CSI data group is sent, the description information of the first CSI data is reported together, such as adding the target description information after the last CSI data or transmitting the last CSI data in a special format.

[0057] It is worth noting that the aforementioned reporting of the first CSI data group may be performed with a CSI data group as the granularity or with a single CSI data as the granularity, and there is no limitation here.

[0058] Among them, if reporting is performed with CSI data group as the granularity, then the terminal sends fifth information to the network side device, and the fifth information includes the at least two CSI data included in the first CSI data group and the first association relationship, and the first association relationship includes the association relationship between the first CSI data and the target description information, so that the network side device can determine which target description information the first CSI data group corresponds to based on the first association relationship.

[0059] If reporting is performed at the granularity of a single CSI data, the terminal sends fifth information to the network-side device, where the fifth information includes the at least two CSI data and a first association relationship, where the first association relationship includes an association relationship between each CSI data and the first CSI data group, or the first association relationship includes an association relationship between each CSI data and the target description information, so that the network-side device determines the description information of each CSI data based on the first association relationship.

[0060] The CSI data mentioned in the embodiments of this application is a multi-dimensional matrix or tensor. The multiple dimensions include spatial, frequency, and time domain dimensions. The spatial dimension can be described by the number of transmit antennas, receive antennas, transmit ports, or receive ports. The frequency dimension can be described by the number of subcarriers, resource blocks, or subbands. The time dimension can be described by time slots, symbols, or frames.

[0061] In addition, the CSI data can be channel information estimated from the received Channel State Information Reference Signal (CSI-RS), or precoding matrix indicator (PMI) information generated during CSI feedback. The CSI data can be used for, but is not limited to, AI model training, communication quality prediction, etc.

[0062] In this embodiment, the terminal obtains at least two CSI data with identical, similar, or associated characteristic information, and sends target description information to the network-side device to describe the characteristic information corresponding to the first CSI data group including the at least two CSI data. Thus, through grouping, the CSI data belonging to the same CSI data group can share the same description information, thereby effectively reducing the data overhead caused by the need to additionally report the description information of each CSI data when reporting the CSI data, avoiding the waste of network resources, and improving data reporting efficiency.

[0063] like Figure 3 FIG. 3 is a flow chart of a data reporting method 300 provided in an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by a terminal, and specifically may be executed by at least one of hardware and software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.

[0064] S310: The terminal obtains at least two CSI data.

[0065] The characteristic information corresponding to the at least two CSI data are the same, similar or related.

[0066] S320: The terminal sends first information to the network side device.

[0067] The first information includes the target description information, and the target description information is used to describe characteristic information corresponding to the first CSI data group, and the first CSI data group includes the at least two CSI data.

[0068] It is understood that the implementation process of S310-S320 may refer to the relevant description in the aforementioned method embodiment 200. Of course, in this embodiment, in addition to referring to the relevant description in the aforementioned method embodiment 200, as an optional implementation, the first CSI data group is obtained by the terminal by grouping multiple acquired CSI data based on a CSI data grouping rule, where the CSI data grouping rule may be determined by protocol agreement, high-layer configuration, network-side configuration, terminal implementation, etc. In this embodiment, the CSI data grouping rule may include, but is not limited to: the characteristic information corresponding to each CSI data in the same CSI data group is the same, similar, or related.

[0069] That is, when grouping CSI data, the terminal can divide CSI data with the same, similar or related characteristic information into one CSI data group. In this way, only one description information needs to be reported for at least two CSI data in a CSI data group, so that the network side device can determine the characteristic information of all CSI data in the first CSI data group, avoiding the signaling overhead caused by the need to report the description information of each CSI data.

[0070] In this embodiment, the characteristic information corresponding to each CSI data in the same CSI data group is the same, similar, or related, and may include but is not limited to at least one of the following 01)-06).

[0071] 01) The channel scenarios corresponding to the CSI data in the same CSI data group are in the same scenario range or list.

[0072] The channel scenarios may include but are not limited to line of sight (LOS) channels, non-line of sight (NLOS) channels, and the like.

[0073] 02) The scenarios of the terminals corresponding to the CSI data in the same CSI data group are in the same scenario range or list.

[0074] The scene in which the terminal is located may be, but is not limited to, an indoor scene, an outdoor scene, an urban scene, a suburban scene, a plain scene, a mountainous scene, etc.

[0075] 03) The data acquisition positions corresponding to the various CSI data in the same CSI data group are located in the same position range or list.

[0076] The data acquisition location may be, but is not limited to, one or more of a cell, a sector, a city, or a region. In this embodiment, the data acquisition location may be identified by a location identifier.

[0077] 04) The data acquisition areas corresponding to the CSI data in the same CSI data group are located in the same area range or list.

[0078] The data acquisition area may be, but is not limited to, one or more of a cell, a sector, a city, a region, a area, etc. In this embodiment, the data acquisition area may be identified by an area identifier.

[0079] 05) The terminal movement speeds corresponding to the CSI data in the same CSI data group are in the same speed range or list.

[0080] For example, the speed range or list may include, but is not limited to, less than 10 km / h, less than 30 km / h, between 30 km / h and 60 km / h, etc. Based on this, the terminal may classify CSI data corresponding to a terminal moving speed less than 10 km / h into one CSI data group, or classify CSI data corresponding to a terminal moving speed less than 30 km / h into one CSI data group, or classify CSI data corresponding to a terminal moving speed between 30 km / h and 60 km / h into one CSI data group, etc.

[0081] For the above-mentioned 01)-05), taking the channel scenario as an example, if the target description information describes a channel scenario, then the network side device can determine that each CSI data in the first CSI data group corresponds to the channel scenario, such as each CSI data is collected based on the channel scenario; if the target description information describes a scenario range or list, then the network side device can determine that the channel scenarios corresponding to each CSI data in the first CSI data group are all within the scenario range or list.

[0082] 06) The time domain interval between two time-domain adjacent CSI data in the same CSI data group is the same, that is, the time interval between multiple consecutive CSI data in a CSI group is the same. In this way, only one time domain interval needs to be reported for a CSI data group to determine the time interval of all time-domain adjacent CSI data in the CSI data group, avoiding the signaling overhead caused by the need to report the time interval of each time-domain adjacent CSI data.

[0083] Based on this, when the terminal groups CSI data, if an interval change occurs in multiple consecutive CSI data, the terminal can group the data before the change point into one CSI data group. This can avoid problems such as different time intervals or CSI data omissions in different adjacent CSI data within the same CSI data group, thereby effectively improving the reliability of CSI data reporting.

[0084] For example, assuming that CSI data 1, CSI data 2, CSI data 3, and CSI data 4 are obtained, where the time interval between CSI data 1 and CSI data 2 is T1, the time interval between CSI data 2 and CSI data 3 is T2, and the time interval between CSI data 3 and CSI data 4 is T3, and T1 is different from T2, then CSI data 1 and CSI data 1 can be divided into one CSI data group, and CSI data 3 and CSI data 4 can be divided into one CSI data group.

[0085] As an optional implementation method, the target description information is used to describe characteristic information corresponding to the first CSI data group. Then, the target description information may include but is not limited to at least one of the following 11)-18).

[0086] 11) The number of CSI data included in the first CSI data group.

[0087] 12) A time domain interval (or time interval) between two CSI data sets that are adjacent in time domain in the first CSI data set.

[0088] 13) A timestamp corresponding to the first CSI data group.

[0089] The timestamp is used to describe the time information of each CSI data in the first CSI data group, such as collection time information, acquisition time information, etc. In this embodiment, one first CSI data group corresponds to one timestamp, that is, the timestamp is defined at the granularity of the CSI data group in this embodiment.

[0090] Optionally, the timestamp corresponding to the first CSI data group may be the timestamp of specific CSI data in the first CSI data group. For example, the specific CSI data may be any CSI data agreed upon in the protocol or specified by the network side or the terminal, such as the first CSI data or the last CSI data in the first CSI data group.

[0091] Based on this, in one implementation, if the time domain interval between two time-domain adjacent CSI data in the first CSI data group is used as a sub-information of the timestamp, then after receiving the target description information, the network-side device can combine the timestamp of the specific CSI data and the time domain interval between two time-domain adjacent CSI data to indirectly calculate the time points corresponding to all CSI data in the first CSI data group, such as the acquisition time points.

[0092] 14) A range or list of terminal moving speeds corresponding to the first CSI data group.

[0093] In an optional implementation, the network side device may perform, but is not limited to, model training of a speed specific model based on a range or list of terminal movement speeds corresponding to the first CSI data group.

[0094] 15) A range or list of channel scenarios corresponding to the first CSI data group, such as the LOS channel or NLOS channel.

[0095] 16) The range or list of scenes in which the terminal corresponds to the first CSI data group, such as indoor scenes, outdoor scenes, urban scenes, suburban scenes, plain scenes, mountainous scenes, etc.

[0096] The channel scenario or the scenario in which the terminal is located corresponding to the first CSI data group described in 15)-16) can be used for, but not limited to, model training of a scenario specific model.

[0097] 17) A range or list of data acquisition locations corresponding to the first CSI data group, such as a cell range or list, a sector range or list, a city range or list, a region range or list, a zone range or list, etc.

[0098] 18) The range or list of the data acquisition area corresponding to the first CSI data group, such as a cell range or list, a sector range or list, a city range or list, a region range or list, a zone range or list, etc.

[0099] The data acquisition position or data acquisition area corresponding to the first CSI data group described in 17)-18) can be used for, but not limited to, model training of a cell / site / region specific model.

[0100] In one possible implementation, when reporting the first CSI data group, the terminal may also receive fourth information (also referred to as a CSI data collection instruction) sent by the network-side device, and acquire or report CSI data based on the fourth information, thereby ensuring consistency in the understanding of the information such as acquisition and reporting of the first CSI data group between the terminal and the network-side device, thereby improving the reliability of the CSI data.

[0101] The fourth information may include but is not limited to at least one of the following 21)-23).

[0102] 21) A reporting method of CSI data, wherein the reporting method includes reporting with a single CSI data as a granularity or reporting with a CSI data group as a granularity.

[0103] In which, when the reporting method of the CSI data includes reporting with a single CSI data as the granularity, the fourth information may further include first indication information, used to indicate the association relationship between each reported CSI data and its corresponding description information, or used to indicate the association relationship between each reported CSI data and the CSI data group to which it belongs.

[0104] For example, in this embodiment, when the terminal reports the first CSI data group, it needs to report the association relationship between each CSI data and the target description information, or report the association relationship between each CSI data and the first CSI data group, so that the network side device can determine the characteristic information corresponding to each reported CSI data.

[0105] When the CSI reporting method includes reporting at the granularity of CSI data groups, the fourth information may further include at least one of second indication information and third indication information. The second indication information is used to indicate the CSI data grouping rule, i.e., the CSI data grouping rule used by the terminal when performing CSI data grouping is indicated by the network-side device; or, the second indication information is used to instruct the terminal to report the CSI data grouping rule, i.e., the CSI data grouping rule used by the terminal when performing CSI data grouping is determined by the terminal and indicated to the network-side device.

[0106] The third indication information is used to indicate an association relationship between the reported CSI data group and the description information corresponding to the CSI group, so that the network side device can determine the description information corresponding to the received CSI data group.

[0107] For example, in this embodiment, when the terminal reports the first CSI data group, it needs to report the association relationship between it and the target description information, so that the network side device can determine the characteristic information corresponding to the reported first CSI data group.

[0108] 22) CSI data acquisition configuration information or acquisition condition information, so that the terminal can acquire CSI data that meets the requirements according to the CSI data acquisition configuration information or acquisition condition information.

[0109] Optionally, the acquisition configuration information or acquisition condition information of the CSI data may include but is not limited to at least one of the port configuration information of the receiving / transmitting end, frequency domain configuration information, time domain configuration information, scenario information, channel quality conditions, etc.

[0110] The port configuration information of the receiving / transmitting end is used to instruct acquisition of the CSI data based on the port configuration of the receiving / transmitting port.

[0111] The frequency domain configuration information is used to indicate the frequency domain configuration used by the terminal when acquiring the CSI data. In this embodiment, the frequency domain configuration information may include, but is not limited to, bandwidth size, bandwidth part (BWP) size and frequency domain location, number of subbands and frequency domain location, number of resource blocks (RBs) and frequency domain location, etc.

[0112] The time domain configuration information is used to indicate the time domain configuration used by the terminal when acquiring the CSI data. In this embodiment, the time domain configuration information may be, but is not limited to, the time domain interval between adjacent CSI data, the acquisition duration of CSI data, and the like.

[0113] The scenario information is used to instruct the terminal to acquire the CSI data in a scenario corresponding to the scenario information. In this embodiment, the scenario information may be, but is not limited to, terminal movement speed, LOS scenario, NLOS scenario, indoor scenario, outdoor scenario, urban scenario, suburban scenario, etc.

[0114] The channel quality condition is used to instruct the terminal to acquire the CSI data under a channel that meets the channel quality condition. In this embodiment, the channel quality condition may be, but is not limited to, collecting and reporting CSI data when conditions described by indicators such as channel quality indicator (CQI), signal to interference plus noise ratio (SINR), signal-to-noise ratio (SNR), and reference signal received power (RSRP) are met.

[0115] 23) Reporting condition information of CSI data, so that the terminal can report CSI data to the network side device according to the reporting condition information of CSI data.

[0116] Among them, the reporting condition information of the CSI data may include but is not limited to at least one of the time information when the CSI data is reported, the number or amount of the CSI data to be reported (such as 1GB, 1T, etc.), the number or amount of CSI data groups to be reported, and the terminal power required when reporting the CSI data.

[0117] Regarding the time information when the CSI data is reported, if the time information is a first time interval, then: the terminal may report the CSI data at the first time interval after calculating the CSI data; or the terminal may report the CSI data at the first time interval after generating the first CSI data group, etc., and there is no restriction here.

[0118] Regarding the terminal power required for reporting the CSI data, if the terminal power is X, then: the terminal may report the CSI data (such as a CSI data group) when the actual detected terminal power is greater than or equal to X, to ensure that the CSI data can be reported in a timely manner.

[0119] It is worth noting that in addition to the aforementioned reporting condition information, other specific conditions, such as the terminal's service busy / idle level, can also be configured through protocol agreement, network-side configuration, etc., so that the terminal reports CSI data when specific conditions are met.

[0120] In one possible implementation, considering that when a terminal reports CSI data, there may be multiple CSI data groups, and some of the description information corresponding to these multiple CSI data groups is the same, while other description information is different for each CSI data group. In this embodiment, the same description information can be reported only once to further reduce the overhead associated with the description information.

[0121] For example, when there are N first CSI data groups, the target description information corresponding to the N first CSI data groups can be divided into first description information and at least one second description information, that is, the target description information can include first description information and at least one second description information. In this case, the first description information can be common description information shared by the N first CSI data groups, and the second description information is non-common description information shared by the N first CSI data groups, where N is an integer greater than or equal to 2. The first description information can be associated with the N first CSI data groups to describe the common characteristics of the N first CSI data groups, and each second description information can be associated with a first CSI data group to describe the non-common characteristics of the corresponding first CSI data group.

[0122] Exemplarily, it is assumed that there are N first CSI data groups, N=4, which are as follows.

[0123] The first CSI data group: contains K1 CSI data; the timestamp of the data group is timestamp1; the terminal moving speed is greater than 30km / h and less than or equal to 60km / h; suburban scene; the cell ID is ID1.

[0124] The second first CSI data group: contains K2 CSI data; the timestamp of the data group is timestamp2; the terminal moving speed is greater than 30km / h and less than or equal to 60km / h; suburban scene; the cell ID is ID1.

[0125] The third first CSI data group: contains K3 CSI data; the timestamp information of the data group is timestamp3; the terminal speed is greater than 30km / h and less than or equal to 60km / h; the scene is suburban; the cell ID is ID1.

[0126] The fourth first CSI data group: contains K4 CSI data; the timestamp of the data group is timestamp4; the terminal moving speed is greater than 30km / h and less than or equal to 60km / h; suburban scene; the cell ID is ID1.

[0127] The four first CSI data groups are discontinuous in timing, or in other words, discontinuous in the time domain. Except for the number of CSI data in each first CSI data group and the timestamp of the CSI data group, all other descriptive information is the same. In this case, the first descriptive information may include {terminal moving speed greater than 30 km / h and less than or equal to 60 km / h; suburban scene; cell ID is ID1}, and the second descriptive information is {CSI number, timestamp} for each first CSI data group.

[0128] In this case, the terminal may report the four first CSI data groups and their description information in an associated manner, that is, report the four first CSI data groups, report the first description information corresponding to one first CSI data group, and report the second description information corresponding to the four first CSI data groups. The first description information is associated with all four first CSI data groups, the first second description information is associated with the first first CSI data group, the second second description information is associated with the second first CSI data group, the third second description information is associated with the third first CSI data group, and the fourth second description information is associated with the fourth first CSI data group.

[0129] In another possible implementation, for the aforementioned target description information, in order to further reduce the overhead of the description information, in this embodiment, the target description information can also be represented by a predetermined identifier. That is, a predetermined identifier can be configured in advance for the description information of the CSI data group, and the terminal and the network side device (i.e., the transmitting and receiving ends) align the correspondence or association between the description information and the predetermined identifier. Then, when the CSI data group needs to be reported, if the description information corresponding to the CSI data group contains the identified description information, the identifier corresponding to the description information and the unidentified description information can be directly reported, thereby replacing the reporting of the description information with the reporting of the identification information, effectively reducing the overhead caused by the description information.

[0130] In this embodiment, the correspondence or association between the description information and the predetermined identifier can be configured through protocol agreement, dynamic interaction, etc. In this embodiment, taking dynamic interaction as an example, the terminal can send second information to the network-side device, where the second information includes the association or correspondence between the description information corresponding to different CSI data groups and the predetermined identifier. In other words, the terminal can configure or establish an identifier (i.e., a predetermined identifier) ​​for the target description information, first description information, second description information, etc. corresponding to the CSI data group, and send the identifier and the corresponding description information to the network-side device for registration.

[0131] Alternatively, the terminal receives third information sent from the network-side device, where the third information includes or is configured with an association or correspondence between description information of different CSI data groups and a predetermined identifier. That is, the network-side device generates description information and a corresponding identifier (i.e., a predetermined identifier) ​​and sends the corresponding association or association between the description information and the identifier to the terminal.

[0132] Based on this, when reporting the first CSI data group, the terminal can report the identifier information of the target description information instead of reporting specific description information, such as reporting the identifier corresponding to the first description information and the identifier corresponding to the second description information, effectively reducing data reporting overhead. In this embodiment, the predetermined identifier reported by the terminal can be one or more.

[0133] Of course, during the CSI data reporting process, for the description information of the unidentified CSI data group, the specific description information may be directly reported.

[0134] In an optional implementation, the terminal also sends terminal capability information to the network side device; wherein, the terminal capability information is used to indicate that the terminal has the ability to report CSI data in groups, so that the network side device can instruct the terminal to collect and report CSI data based on the terminal capability information, so that the network side device's instructions to the terminal match the terminal capabilities.

[0135] Optionally, the terminal capability information may include but is not limited to at least one of the following: whether the terminal supports CSI data group reporting, a CSI data grouping method supported by the terminal, etc.

[0136] Among them, as to whether the terminal supports CSI data group reporting, if the terminal supports CSI data group reporting, then the network side device can instruct the terminal to report the CSI data in a granularity of CSI data group; otherwise, it can be reported in a granularity of single CSI data.

[0137] For the CSI data grouping mode supported by the terminal, the network-side device may instruct the terminal to collect and report CSI data according to the CSI data grouping mode supported by the terminal. Optionally, the CSI data grouping mode may include but is not limited to at least one of the following modes 1 to 6.

[0138] Method 1: CSI data grouping based on the time domain interval when the CSI data is acquired.

[0139] Method 2: CSI data grouping based on the terminal's moving speed when the CSI data is acquired.

[0140] Method 3: CSI data grouping based on the channel scenario when the CSI data is acquired.

[0141] Method 4: CSI data grouping based on the scenario in which the terminal is located when the CSI data is acquired.

[0142] Mode 5: CSI data grouping based on the data acquisition position corresponding to the CSI data.

[0143] Mode 6: CSI data grouping based on the data acquisition area corresponding to the CSI data.

[0144] In this embodiment, a method is proposed to report the required CSI data in groups, and the CSI data in each group has the same, similar, or related characteristic information, so that only one characteristic information is reported in each group. This can significantly reduce the overhead of CSI data collection and improve the efficiency of data collection.

[0145] like Figure 4 FIG. 4 is a flow chart of a data reporting method 400 provided in an exemplary embodiment of the present application. The method 400 may be, but is not limited to, executed by a terminal, and specifically may be executed by at least one of hardware and software installed in the terminal. In this embodiment, the method 400 may include at least the following steps.

[0146] S410: The terminal obtains at least two CSI data.

[0147] The characteristic information corresponding to the at least two CSI data are the same, similar or related.

[0148] In this embodiment, the terminal may acquire CSI data at a predetermined time interval, may acquire CSI data according to a received data acquisition instruction, or may receive CSI data from other terminals, etc., which is not limited here.

[0149] S420: The terminal sends first information to the network side device.

[0150] Among them, the first information includes the target description information, and the target description information is used to describe the characteristic information corresponding to the at least two CSI data, such as the terminal characteristics corresponding to the at least two CSI data, the data characteristics of the at least two CSI data, etc., which are not limited here.

[0151] It is worth noting that, compared to related technologies that report CSI data at the CSI data granularity, which requires reporting description information corresponding to each CSI data to describe the characteristic information of the CSI data, thereby resulting in high data overhead and low data reporting efficiency when reporting CSI data, in this embodiment, for at least two CSI data sets with identical, similar, or associated characteristic information, only one description information, namely, the target description information, needs to be reported. This allows the network-side device to know the characteristic information of each CSI data set included in the at least two CSI data sets, eliminating the need to report the characteristic information for each CSI data set separately. This effectively reduces data overhead when reporting CSI data, avoids waste of network resources, and improves data reporting efficiency.

[0152] In this embodiment, each CSI data in the at least two CSI data may correspond to a time (such as a data collection time), that is, the at least two CSI data are CSI data corresponding to different time.

[0153] In an optional implementation, the terminal may have multiple transmission modes or orders when sending the at least two CSI data and the target description information to the network side device.

[0154] For example, Figure 5aAs shown, the target description information may be sent before the at least two CSI data.

[0155] For example, Figure 5b As shown, the target description information can be sent after the at least two CSI data are sent.

[0156] For example, Figure 5c As shown, the target description information may be reported together with the first CSI data among the at least two CSI data when it is sent, such as by placing the target description information after the first CSI data among the at least two CSI data or transmitting the first CSI data in a special format.

[0157] For example, Figure 5d As shown, when the last CSI data among at least two CSI data is sent, the description information of the first CSI data is reported together, such as the target description information is added after the last CSI data or the last CSI data is transmitted in a special format.

[0158] It is worth noting that for the reporting of the at least two CSI data mentioned above, if the reporting is performed with a single CSI data as the granularity, then the terminal sends fifth information to the network side device, and the fifth information includes the at least two CSI data and a first association relationship. The first association relationship is an association relationship between each of the CSI data and the target description information, so that the network side device determines the special description information of each CSI data based on the first association relationship.

[0159] As an optional implementation, the target description information may include but is not limited to at least one of the following 31)-38).

[0160] 31) The number of CSI data included in the at least two CSI data.

[0161] 32) A time domain interval (or time interval) between two CSI data that are adjacent in time domain among the at least two CSI data.

[0162] 33) Timestamps corresponding to the at least two CSI data.

[0163] The timestamp is used to describe the time information of each CSI data, such as collection time information, acquisition time information, etc. In this embodiment, one CSI data corresponds to one timestamp.

[0164] 34) A range or list of terminal movement speeds corresponding to the at least two CSI data.

[0165] In an optional implementation, the network side device may perform, but is not limited to, model training of a speed specific model based on a range or list of terminal movement speeds corresponding to the at least two CSI data.

[0166] 35) The range or list of channel scenarios corresponding to the at least two CSI data, such as the LOS channel or NLOS channel, etc.

[0167] 36) The range or list of scenes in which the terminal corresponds to the at least two CSI data, such as indoor scenes, outdoor scenes, urban scenes, suburban scenes, plain scenes, mountainous scenes, etc.

[0168] The channel scenarios or terminal scenarios corresponding to the at least two CSI data described in 35)-36) can be used for, but not limited to, model training of a scenario-specific model.

[0169] 37) A range or list of data acquisition locations corresponding to the at least two CSI data, such as a cell range or list, a sector range or list, a city range or list, a region range or list, a area range or list, etc.

[0170] 38) The range or list of data acquisition areas corresponding to the at least two CSI data, such as a cell range or list, a sector range or list, a city range or list, a region range or list, a zone range or list, etc.

[0171] The data acquisition location or data acquisition area corresponding to the at least two CSI data described in 37)-38) can be used for, but not limited to, model training of a cell / site / region specific model.

[0172] In one possible implementation, when the terminal reports the at least two CSI data, it can also receive fourth information (also called CSI data collection instructions) sent by the network-side device, so as to acquire or report CSI data based on the fourth information, thereby ensuring consistency in the understanding of the terminal and the network-side device regarding the acquisition, reporting, and other information of the at least two CSI data, thereby improving the reliability of the CSI data.

[0173] It can be understood that regarding the fourth information, reference can be made to the relevant description in the aforementioned method embodiment 300, which will not be repeated here.

[0174] In another possible implementation, for the aforementioned target description information, in order to further reduce the overhead of the description information, in this embodiment, the target description information can also be represented by a predetermined identifier. That is, a predetermined identifier can be configured in advance for the description information corresponding to the CSI data, and the terminal and the network-side device (i.e., the transmitting and receiving ends) align the correspondence or association between the description information and the predetermined identifier. Then, when the description information corresponding to the CSI data (such as the target description information) needs to be reported, if the description information contains the identified description information, the identifier corresponding to the description information and the unidentified description information can be directly reported, thereby replacing the reporting of the description information with the reporting of the identification information, effectively reducing the overhead caused by the description information.

[0175] In this embodiment, the correspondence or association between the descriptive information and the predetermined identifier can be configured through protocol agreement, dynamic interaction, or other methods. In this embodiment, taking dynamic interaction as an example, the terminal can send a second message to the network-side device, where the second message includes the association or correspondence between different descriptive information and the predetermined identifier. In other words, the terminal can configure or establish an identifier (i.e., a predetermined identifier) ​​for the descriptive information, and send the identifier and the corresponding descriptive information to the network-side device for registration.

[0176] Alternatively, the terminal receives third information sent from the network-side device, wherein the third information includes associations or correspondences between different descriptive information and predetermined identifiers. That is, the network-side device generates descriptive information and its corresponding identifier (i.e., the predetermined identifier), and sends the corresponding associations or associations between the descriptive information and the predetermined identifier to the terminal.

[0177] Based on this, when reporting the target description information corresponding to the at least two CSI data, the terminal can report the identifier information of the target description information instead of reporting the specific content of the target description information, effectively reducing data reporting overhead. In this embodiment, the predetermined identifier reported by the terminal can be one or more.

[0178] Of course, during the CSI data reporting process, for unidentified description information, the specific content of the description information can be directly reported.

[0179] In this embodiment, the terminal obtains at least two CSI data with the same, similar, or associated characteristic information and sends target description information to the network-side device to describe the characteristic information corresponding to the at least two CSI data. As a result, the at least two CSI data with the same, similar, or associated characteristic information share the same description information (also referred to as characteristic description information), thereby effectively reducing the data overhead caused by the need to additionally report the description information of each CSI data when reporting the CSI data, avoiding waste of network resources, and improving data reporting efficiency.

[0180] Based on the description of the data reporting method provided by the present application in the aforementioned method embodiments 200-400, for ease of understanding, the following further combines Figure 6 This application further provides an exemplary description of the implementation process of the data reporting method provided in this application, as follows, wherein it is assumed that the target description information is used to describe the characteristic information corresponding to the first CSI data group.

[0181] S610: The terminal sends terminal capability information to the network side device, indicating that the terminal has the capability of reporting CSI data in groups.

[0182] S620: The network side device sends fourth information, ie, a CSI data collection instruction, to the network side device according to the terminal capability information.

[0183] The fourth information may include but is not limited to a reporting method of CSI data, acquisition configuration information or acquisition condition information of CSI data, reporting condition information of CSI data, etc.

[0184] S630: After receiving the fourth information, the terminal obtains at least two CSI data, that is, a first CSI data group.

[0185] Optionally, the terminal may obtain multiple CSI data according to the fourth information, and then group the multiple CSI data according to a CSI data grouping rule to obtain the first CSI data group.

[0186] S640: The terminal reports first information to the network-side device, where the first information includes target description information, and the target description information is used to describe characteristic information corresponding to the first CSI data group.

[0187] It should be noted that the implementation process of S610-S640 included in this example can refer to the relevant description in the aforementioned method embodiment 200 or 300, and achieve the same or corresponding technical effects. To avoid repetition, it will not be repeated here.

In this embodiment, the method 700 may include at least the following steps.
