Description

Method, device and communication system for receiving and sending data Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies. Background Art

[0002] Massive multiple-input multiple-output (MIMO) technology is one of the key technologies for 5G mobile communications. MIMO can provide higher channel capacity, but achieving these benefits depends on obtaining accurate channel state information.

[0003] In MIMO technology, terminal devices measure spatial channels and provide channel state information (CSI) back to the network. Based on this CSI, the network selects an appropriate precoding matrix for downlink transmission to the terminal, minimizing the probability of bit errors in the terminal's reception.

[0004] The channel state information generation and feedback process can be summarized as follows. The network device sends a channel state information reference signal (CSI-RS) to each terminal device. The terminal device estimates the channel using the received CSI-RS and obtains an estimate of the spatial channel matrix. The terminal device further uses the estimated spatial channel to obtain CSI. In new radio (NR) technology, CSI feedback is implicit. That is, the terminal device feeds back CSI in the form of recommended transmission parameters to the network device. These transmission parameters include the channel state information reference signal resource indicator (CQI), precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), synchronization signal block resource indicator (SSBRI), layer indicator (LI), rank indicator (RI), and physical layer RSRP (L1-RSRP). The base station can directly use the parameters recommended by the terminal device for downlink transmission, or it can choose not to use the recommended parameters.

[0005] When using the traditional codebook method to feed back CSI, if the rank of the spatial channel matrix estimated by the terminal device is greater than 1, the RI fed back by the terminal device to the base station (if reported) may be greater than 1. In this case, the PMI is a multi-rank codebook. In NR Rel-15, two codebooks, type I and type II, are defined. The former is a conventional precision codebook and can be used for single-user multiple input multiple output (SU-MIMO) and multi-user multiple input multiple output (MU-MIMO) transmission. The latter is a high-precision codebook, mainly used in MU-MIMO scenarios. The latter has higher accuracy than the former, but has higher overhead. Both NR codebooks use a parameterized codebook structure and are divided into two levels (W=W1W2), where W1 describes the long-term, wideband characteristics of the channel and contains an oversampled DFT beam (group); W2 describes the short-term, subband characteristics of the channel. For the above two codebooks, the selection method of W1 is the same. Regarding the selection of W2, the type I codebook consists of a weighted column selection vector, which selects a beam for the subband from the oversampled beams in W1. In the high-precision type II codebook, W2 is used to linearly combine the DFT beams in W1.

[0006] To address the excessive overhead of the Type II codebook, Rel-16 defines an enhanced Type II codebook (e-type II codebook). The e-type II codebook still uses a two-level structure: reporting a set of wideband beams and then adding a set of narrowband combining coefficients to each beam. The enhancement to the Rel-16 e-type II codebook leverages frequency domain correlation to reduce reporting overhead. Furthermore, the e-type II CSI allows for a two-fold increase in the frequency domain granularity of PMI reporting.

[0007] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0008] Summary of the Invention

[0009] There is a certain delay in the generation of CSI after the terminal device measures the channel, and there is also a delay in the use of the CSI after the base station performs scheduling (such as MU-MIMO scheduling) after receiving the CSI. Therefore, the time at which the channel corresponding to the CSI is different from the time at which it is applied, which is called channel aging. In some scenarios, such as when the terminal device moves at a fast speed (for example, greater than or equal to 30km / h) or the surrounding environment changes rapidly, the channel aging problem will be serious. In order to cope with the channel aging problem, in Rel-18, an auto-regression (AR) algorithm is used to predict the channel at more than one moment in the future (relative to the moment when CSI is generated), and an enhanced type II codebook for predicted PMI is defined. In this application, we refer to it as the Rel-18 codebook. For the case of predicting the channel at one moment in the future, the Rel-18 codebook is similar to the Rel-16 codebook. In the case of predicting the channel at more than one time instant in the future, the Rel-18 codebook compresses the channel in the Doppler domain by utilizing the time correlation of the channels at more than one time instant.

[0010] With the development of artificial intelligence / machine learning (AI / ML) technology, applying AI / ML technology to the physical layer of wireless communications to solve the difficulties of traditional methods has become a current technical direction.

[0073] Embodiments of the first aspect

[0074] An embodiment of the first aspect of the present application provides a method for receiving data, which is applied to a network device.

[0075] FIG3 is a schematic diagram of a method for receiving data. As shown in FIG3 , the method includes:

[0076] 301. The network device sends a first configuration to the terminal device, where the first configuration is used to configure the terminal device to obtain first data for artificial intelligence model performance monitoring and / or artificial intelligence model training; and

[0077] 302. Receive the first data sent by the terminal device.

[0078] In operation 301, the network device sends a first configuration to the terminal device; in operation 302, the terminal device can collect and send data based on the first configuration, wherein the data obtained by the terminal device through data collection is the collected data, and the data sent by the terminal device based on the collected data is the first data.

[0079] The collected data may be ground-truth channel state information (CSI), for example, including at least one of the following data: information about right singular vectors of a spatial channel matrix, and information about the spatial channel matrix. The information about right singular vectors of the spatial channel matrix may refer to right singular vectors of the spatial channel matrix.

[0080] The first data may be the collected data itself, or the collected data may be processed to generate the first data, and the terminal device sends the first data.

[0081] After receiving the first data sent by the terminal device, the network device can use the first data to perform artificial intelligence (AI / ML) model performance monitoring and / or artificial intelligence model training.

[0082] The first configuration includes at least one of the following information:

[0083] First information, which is used to instruct the terminal device to collect data;

[0084] Second information, which is used to indicate information about channel state information (CSI) resource settings for data collection by the terminal device;

[0085] third information, which is used to indicate a method for sending the first data;

[0086] fourth information, which is used to indicate a report amount of sending the first data;

[0087] fifth information, which is used to indicate the number of layers or the limit of the number of layers for collecting data;

[0088] sixth information, which is used to indicate how the first data represents the collected data;

[0089] seventh information indicating the amount of collected data; and

[0090] The eighth information is used to indicate frequency domain information of the collected data.

[0091] The method of the present application is described in detail below through different embodiments.

[0092] Example 1:

[0093] The network device performs AI / ML model performance monitoring. The network device receives the CSI generated by the AI / ML-based CSI generation model from the terminal device and uses the AI / ML-based CSI reconstruction model to recover the CSI.

[0094] One monitoring method is to calculate the similarity between the output of the AI / ML-based reconstruction model on the network device side (or called recovered CSI) and the true CSI (ground-truth CSI), and compare it with a predefined and / or standard-specified and / or network device-configured threshold. The higher the similarity, the better the performance of the bilateral AI / ML model (the bilateral AI / ML model includes: an AI / ML-based CSI generation model and an AI / ML-based CSI reconstruction model). Conversely, the lower the similarity, the worse the performance of the bilateral AI / ML model (i.e., the AI / ML-based CSI generation model and the AI / ML-based CSI reconstruction model). When the similarity is lower than the threshold, the performance of the bilateral AI / ML model is unacceptable.

[0095] The similarity can be described by squared generalized cosine similarity (SGCS). The expression of SGCS is as follows:

[0096] where w i is the true CSI at the ith frequency domain unit, is the output of the AI / ML-based reconstruction model at the i-th frequency domain unit (i.e., the recovered CSI), and N is the total number of frequency domain units. E{·} represents the number of The average operation of the samples.

[0097] Since the network device side does not have real CSI, when performing AI / ML model monitoring on the network device side, the terminal device needs to send data related to the real CSI to the network device. The terminal device needs to perform data collection to obtain collected data (e.g., real CSI), and then send first data related to the collected data to the network device.

[0098] Embodiment 1 provides a method for a network device to configure a terminal device to obtain first data, corresponding to operation 301 in Figure 3. In various embodiments of the present application, "the terminal device obtains the first data" may also be referred to as "the terminal device performs data collection."

[0099] The method in which the network device configures the terminal device to obtain the first data may include the following three configuration methods.

[0100] The first configuration method: the network device sends the first configuration via an RRC message or other message. In the first method, the message sending the first configuration is also used to trigger the terminal device to obtain the first data.

[0101] The first method is described below.

[0102] In some implementations, the first possibility of the first configuration is a CSI report configuration. For example, one or more of the first information to the eighth information may be added to the CSI report configuration as the first configuration.

[0103] 1. The first information is used to instruct the terminal device to collect data.

[0104] The first information in the first configuration can be optional. For example, the default setting is to not collect data. This has the beneficial effect of sending on demand, saving signaling overhead. It can also be mandatory, which has the beneficial effect of clearly and unambiguously indicating whether to collect data, making it simple and clear.

[0105] 2. The second information is used to instruct the terminal device on the CSI resource settings for data collection.

[0106] In some embodiments, the second information is optional. If it is not provided, the terminal device uses the information of the CSI resource setting for channel measurement associated with the CSI report configuration.

[0107] In some implementations, the second information is mandatory. In this case, the CSI resource configuration information for CSI reporting and the CSI resource configuration information for data collection may be the same or different.

[0108] The time domain characteristics of the channel state information (CSI) resource setting corresponding to the second information and the channel state information (CSI) resource setting for generating the channel state information (CSI) are the same or different. The beneficial effect of the two being the same is: simple implementation and simple logic. The beneficial effect of the two being different is: saving reference signal overhead. Specifically, it is possible that the terminal device is required to send channel state information (CSI) only at individual moments, then the channel state information (CSI) resource setting for generating the channel state information (CSI) can be non-periodic, that is, the channel state information reference signal (CSI-RS) is sent on demand, saving reference signal overhead; on the other hand, the terminal device may need to collect a large amount of data, then the channel state information (CSI) resource setting corresponding to the second information can be periodic or semi-continuous.

[0109] Some examples are as follows, not limited to the following two examples: For example, the channel state information (CSI) resource setting for generating the channel state information (CSI) is aperiodic, and the channel state information (CSI) resource setting corresponding to the second information is aperiodic, semi-persistent, or periodic.

[0110] For example, the channel state information (CSI) resource setting corresponding to the second information is periodic or semi-continuous, the channel state information (CSI) resource setting for generating the channel state information (CSI) is periodic or semi-continuous, and the period of the first channel state information reference signal (CSI-RS) resource under the channel state information (CSI) resource setting corresponding to the second information configured by the network device and the period of the second channel state information reference signal (CSI-RS) resource under the channel state information (CSI) resource setting for generating the channel state information (CSI) are the same or different.

[0111] in:

[0112] The period of the first channel state information reference signal (CSI-RS) resource is different from the period of the second channel state information reference signal (CSI-RS) resource, and the smaller period of the first channel state information reference signal (CSI-RS) resource and the second channel state information reference signal (CSI-RS) resource is used for data collection and generation of channel state information (CSI). For example, the period of the CSI-RS (periodic and / or semi-persistent) used for data collection may be shorter than the period of the CSI-RS (periodic and / or semi-persistent) used for generating CSI, that is, data with a specific period needs to be collected, and a large amount of data needs to be collected, but CSI is not necessarily reported for each collected CSI-RS. In this way, CSI-RS that meets the required period can be collected, and the amount of collected data can be increased, and CSI at unnecessary moments does not need to be reported, thereby saving overhead; or

[0113] The periodicity of the first channel state information reference signal (CSI-RS) resource is shorter than the periodicity of the second channel state information reference signal (CSI-RS) resource; or

[0114] The period of the first channel state information reference signal (CSI-RS) resource is the same as the period of the second channel state information reference signal (CSI-RS) resource, and the first channel state information reference signal (CSI-RS) resource or the second channel state information reference signal (CSI-RS) resource is used for data collection and generation of channel state information (CSI).

[0115] 3. The third information is used to indicate the method of sending the first data.

[0116] in:

[0117] The manner of sending the first data indicated by the third information is periodic, aperiodic, or semi-continuous; and / or

[0118] The manner of sending the first data indicated by the third information is to send the first data on a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH); and / or

[0119] The manner of sending the first data indicated by the third information is the same as or different from the manner of sending a channel state information (CSI) report.

[0120] For example:

[0121] The manner of sending the CSI report and sending the first data are both periodic, and the periods and / or time slot offsets of the two are the same or different; or

[0122] The manner of sending the CSI report is aperiodic, and the manner of sending the first data is periodic; or the manner of sending the CSI report and the manner of sending the first data are both semi-continuous; or

[0123] The CSI report is sent on the PUCCH, and the first data is sent on the PUSCH; or both the CSI report and the first data are sent on the PUSCH.

[0124] 4. Fourth information, used to indicate a reported amount of the first data sent. The reported amount indicated by the fourth information includes precoding matrix information, / or channel quality indicator information, / or channel state information reference signal resource information, / or information about the layer of the collected data, and / or information about the number of layers of the collected data.

[0125] 5. The fifth information is used to indicate the number of layers or the limit of the number of layers for collecting data.

[0126] Network devices may need to collect data from all spatial layers, or only a subset of them. For example, a network device may need to monitor the performance of an AI / ML model across all spatial layers, or the performance of AI / ML models across all spatial layers. Another example is that a network device may only need to monitor the performance of an AI / ML model across a subset of spatial layers, such as the strongest spatial layer (the first spatial layer).

[0127] The value corresponding to the fifth information may be the same as or different from the value corresponding to the rank indicator restriction or the value corresponding to the rank restriction. Both have the same beneficial effect of simple implementation, and the limit on the number of layers for collecting data is the same as the limit on the number of layers for sending channel state information, avoiding the collection of useless data. The benefit of the former being less than the latter is on-demand data collection, which is highly targeted. In some scenarios, if only the performance of the AI / ML model of a specific spatial layer needs to be monitored, only data from that spatial layer needs to be collected. Or, in some scenarios, if only the AI / ML models of the two highest-power spatial layers need to be trained, only data from these two spatial layers needs to be collected. The benefit of the former being less than the latter is that all data is collected, resulting in more comprehensive and large-scale data. In some scenarios, channel state information for only one spatial layer may need to be fed back, and downlink transmission only uses this single transmission layer. However, data from all spatial layers needs to be collected for model training, or data from all spatial layers needs to be collected to monitor the performance of inactive AI / ML models for future use.

[0128] The fifth information can be optional. If the fifth information is omitted, data for all airspace layers can be collected by default, or data for only a pre-agreed portion of airspace layers can be collected by default, such as the first airspace layer (the strongest airspace layer). The fifth information can also be mandatory. The beneficial effect is that the configuration is straightforward and clear, and the collection and reporting of data for unnecessary airspace layers is avoided, saving reporting overhead and reducing the complexity and storage requirements of terminal device implementation.

[0129] 6. Sixth information, used to indicate how the first data represents the collected data. The terminal device needs to represent the collected data as the first data and send the first data to the network device.

[0130] The way in which the first data indicated by the sixth information represents the collected data may be, for example, at least one of the following ways:

[0131] Method a: scalar quantize at least one component (eg, each component) of the collected data, for example, scalar quantize each component of the right singular vector of the spatial channel matrix.

[0132] Method b: using a first method to represent at least a portion of the collected data, the first method being a codebook specified by the 3rd Generation Partnership Project (3GPP) standardization or a method obtained by expanding the value range of at least one parameter of the codebook specified by the 3GPP standardization.

[0133] In some examples of the above method b, the network device also needs to configure the value or value range of the parameter of the first method. The parameter is used to describe one or more of the following:

[0134] The number of channel state information reference signal (CSI-RS) antenna ports; and / or the number of antenna ports in the first dimension in one polarization direction; and / or the number of antenna ports in the second dimension in one polarization direction; and / or the number of antenna panels; and / or information on oversampling of spatial basis; and / or the number of spatial basis; and / or the number of frequency domain basis; and / or the number of time domain basis; and / or information on the number of non-zero combining coefficients; and / or information on the number of subbands of precoding matrix indicator (PMI); and / or the number of time moments to which the information of the channel matrix included in a precoding matrix indicator (PMI) belongs; and / or a quantization method for the reference amplitude; and / or a quantization method for the differential amplitude; and / or a quantization method for the phase.

[0135] In some examples of the above-mentioned approach b, the codebook specified by the 3rd Generation Partnership Project (3GPP) standardization includes at least one of the following:

[0136] Type I single-panel codebook, Type I multi-panel codebook, Type II codebook, Type II port selection codebook, enhanced Type II codebook, enhanced Type II port selection codebook, further enhanced Type II port selection codebook, enhanced Type II codebook for CJT, further enhanced Type II port selection codebook for CJT, Enhanced Type II codebook for predicted PMI, further enhanced Type II port selection codebook for predicted PMI.

[0137] In some examples of the above-mentioned method b, the sixth information instructs the terminal device to use the enhanced second-category codebook or expand the value range of at least one parameter of the enhanced second-category codebook to represent data collected at one moment. The beneficial effect is that the data representation is highly accurate, and one PMI only has data at one moment, which is simple and easy to read. In other examples, the sixth information instructs the terminal device to use the enhanced second-category codebook indicated for the predicted precoding matrix or expand the value range of at least one parameter of the enhanced second-category codebook indicated for the predicted precoding matrix to represent data collected at more than one moment. Using this method, one PMI can contain data at more than one moment (it can be one or more than one), and compression of data at more than two moments can be achieved, thereby reducing the number of bits required to represent the data, thereby reducing the overhead of sending data compared to the "using the enhanced second-category codebook or expanding the value range of at least one parameter of the enhanced second-category codebook".

[0138] For detailed description of the first method, please refer to Example 2.

[0139] 7. The seventh information is used to indicate the amount of data collected.

[0140] 8. The eighth information is used to indicate the frequency domain information of the collected data. The frequency domain information includes, for example, the number of subbands, the size of subbands, and / or the number of PRBs in a bandwidth part.

[0141] The eighth information is optional. If it is not set, the frequency domain information for data collection is the same as the frequency domain information for CSI reporting. If it is not set, the frequency domain information for data collection is different from the frequency domain information for CSI reporting. For example, the frequency domain range for data collection may be a subset of the frequency domain range for CSI reporting.

[0142] For the first possibility of the first configuration, the terminal device sends the first data to the network device via uplink control information (UCI). The CSI and the first data may be sent in the same CSI report. The CSI and the first data may also be sent in different reports, that is, the CSI is sent in a CSI report and the first data is sent in another CSI report; or, the CSI is sent in a CSI report and the collected data is sent in a newly defined report, which is, for example, an independent report.

[0143] In the first possibility of the first configuration, at least part of the information of the first configuration is information added to a channel state information (CSI) reporting configuration or a modification of at least part of the information in the channel state information (CSI) reporting configuration.

[0144] In the first possibility, the first configuration may include at least one of the above-mentioned first to eighth information, wherein, in the first to eighth information, if a certain information is optional, then when the information is not included in the first configuration, the content indicated by the information can be obtained from the channel state information (CSI) report configuration.

[0145] A second possibility of the first configuration is a separately defined configuration. For example, at least a portion of the information of the first configuration is information in a separately defined configuration. The separately defined configuration may be named, for example, uplink control information (UCI) configuration, data collection configuration, or AI / ML-based CSI reporting configuration. In this second possibility, the first configuration may include at least one of the first to eighth information described above, where each information may be mandatory.

[0146] In the second possible embodiment of the first configuration, the terminal device may send the first data to the network device via uplink control information (UCI), and / or media access control element (MAC CE) signaling, and / or RRC messages. The use of UCI has the advantage of fast transmission speed and low latency. The use of RRC messages has the advantage of a large amount of data transmitted. The use of MAC CE signaling has the advantage of achieving a certain balance between signaling latency and the amount of data transmitted.

[0147] In the first embodiment, a second configuration method in which the network device configures the terminal device to obtain the first data is as follows.

[0148] Second configuration method: The network device sends the first configuration via an RRC message. The relevant descriptions in the first configuration method above can also be applied to the second configuration method.

[0149] The difference between the second configuration method and the first configuration method is that the first configuration is inactive by default, and the network device activates the first configuration by sending a signaling to the terminal device, where the signaling is a Media Access Control Element (MAC CE) signaling.

[0150] In the second configuration method, the trigger for the terminal device to obtain the first data (or the terminal device to collect data) requires signaling (e.g., MAC CE signaling) activation. In addition, in some embodiments, MAC CE signaling can be deactivated to cause the terminal device to stop data collection.

[0151] The second configuration method has the following advantages: only one RRC configuration is required, saving configuration signaling overhead; in addition, starting and stopping data collection can be achieved through MAC CE signaling activation and deactivation, without the need to reconfigure RRC messages.

[0152] In the second configuration method, the first configuration may be the first possibility, i.e., at least a portion of the information in the first configuration is information added to or modified from a channel state information (CSI) report configuration; or the first configuration may be the second possibility, i.e., the first configuration is a separately defined configuration, for example, at least a portion of the information in the first configuration is information in a separately defined configuration. For descriptions of the first and second possibilities, reference may be made to the relevant descriptions in the first configuration method.

[0153] For the first possible configuration, the terminal device sends the collected data to the network device via UCI. For the second possible configuration, the terminal device may send the collected data to the network device via UCI, MAC CE signaling, or RRC message. The advantage of using UCI is fast transmission speed and low latency. The advantage of using RRC message is a large amount of data sent. The advantage of using MAC CE signaling is a certain balance between signaling delay and the amount of data sent.

[0154] Third configuration method: The network device sends the first configuration via an RRC message. The relevant descriptions in the first configuration method above are applicable to the third configuration method.

[0155] The third configuration method differs from the first configuration method in that the first configuration is inactive by default, and the network device activates the first configuration by sending a signaling to the terminal device, such as downlink control information (DCI) signaling, and triggers the terminal device to collect data.

[0156] The downlink control information (DCI) signaling may be a newly defined DCI signaling (eg, independently configured DCI signaling), or a field added to an existing DCI, or unused fields or reserved code points in the existing DCI may be repurposed.

[0157] The third configuration method has the following advantages: only one RRC configuration is required, thus saving configuration signaling overhead; and starting data collection only requires a DCI indication, without the need to reconfigure the RRC message.

[0158] The third configuration method can be combined with the second configuration method. For example, the network device selects a subset of the first configuration through MAC CE signaling, and then activates at least one configuration in the subset through DCI signaling, and triggers the terminal device to collect data.

[0159] In this third configuration method: the first configuration may be the first possibility, that is, at least part of the information of the first configuration is information added to the channel state information (CSI) report configuration or is a modification of at least part of the information in the channel state information (CSI) report configuration; or the first configuration may be the second possibility, that is, the first configuration is a separately defined configuration, for example, at least part of the information of the first configuration is information in a separately defined configuration. For descriptions of the first possibility and the second possibility, reference may be made to the relevant description in the first configuration method.

[0160] For the first possible configuration, the terminal device sends the collected data to the network device via UCI. For the second possible configuration, the terminal device may send the collected data to the network device via UCI, MAC CE signaling, or RRC message. The advantage of using UCI is fast transmission speed and low latency. The advantage of using RRC message is a large amount of data sent. The advantage of using MAC CE signaling is a certain balance between signaling delay and the amount of data sent.

[0161] Example 2:

[0162] Embodiment 2 can be applied to artificial intelligence model training and / or artificial intelligence model performance monitoring.

[0163] Since the terminal device needs to send the collected data to the network device, when choosing a method to represent the data, not only the accuracy of the data representation should be considered, but also the overhead of sending the data. As shown in Example 1, one way to describe the data is to represent each component of the real CSI (vector) using scalar quantization. The characteristics of this method of representing data are high accuracy and high overhead. In order to reduce overhead and maintain good performance as much as possible, the first method given in Example 1 of the invention can be used to represent the collected data (i.e., the real CSI). The first method is a code book specified by 3GPP standardization or a method obtained by expanding the value range of at least one parameter of the code book specified by 3GPP standardization.

[0164] The 3GPP-specified codebook is a method for terminal devices to represent actual CSI. This allows for reporting CSI with relatively low overhead and recommending precoding matrices for network devices. The 3GPP-specified codebook can be used to represent collected data. Note that the design of the 3GPP-specified codebook, including its accuracy and overhead, is intended to recommend precoding matrices to network devices.

[0165] The beneficial effect of using a method obtained by expanding the value range of at least one parameter of the codebook specified by the 3GPP standard to represent the true CSI is to improve the accuracy of the collected data (such as the true CSI):

[0166] On the one hand, for AI / ML model monitoring scenarios on network devices, improving the accuracy of the representation of real CSI can better describe the similarity between the recovered CSI and the real CSI, thereby improving the accuracy of the model monitoring results;

[0167] On the other hand, in AI / ML model training scenarios, improving the accuracy of real CSI representation can enable AI / ML models to better learn real channel information, thereby obtaining better AI / ML models.

[0168] In some embodiments, the collected data is represented by using the enhanced second-category codebook or expanding the value range of at least one parameter of the enhanced second-category codebook. It is used to represent the collected data at one moment, and the beneficial effect is that the data representation is high in accuracy, and one PMI only has data at one moment, which is simple and easy to read. In some embodiments, the collected data is represented by using the enhanced second-category codebook indicated by the predicted precoding matrix or expanding the value range of at least one parameter of the enhanced second-category codebook indicated by the predicted precoding matrix. Using this method, when one PMI contains data at more than one moment (it can be one or more than one), compression of data at more than two moments can be achieved, thereby reducing the number of bits required to represent the data, thereby reducing the overhead of sending data.

[0169] In some embodiments, the number of spatial layers of data collected is the same as the number of spatial layers of the CSI. In some embodiments, the number of spatial layers of data collected is different from the number of spatial layers of the CSI. The network device may collect more or less data than the number of spatial layers of the CSI as needed. For example, if the data quality is poor, the network device only collects data from the strongest spatial layers; or if the data quality is good, the network device collects more data than the number of spatial layers of the CSI for AI / ML model training. For another example, if the network device only needs to monitor the performance of the AI / ML model in the strongest spatial layer, the network device only collects data from the strongest spatial layer.

[0170] In some implementations, expanding the value range of at least one parameter of the enhanced second-category codebook includes expanding the value range of at least one of the following parameters:

[0171] 1. Value of L: Its value range can be expanded. For example, L=5 and / or L=6 and / or L=7 and / or L=8 and / or L=9 can be added to the parameter value range of the enhanced second-category codebook.

[0172] 2. β value: Its value range can be expanded. For example, β=0.6 is added to the parameter value range of the enhanced second-category codebook.

[0173] 3.p v The value of (v=1,2): Its value range can be expanded. For example, add p to the parameter value range of the enhanced second type codebook. v =0.65 and / or

[0174] 4.p v The value of (v=3,4): Its value range can be expanded. For example, add p to the parameter value range of the enhanced second type codebook. v =0.3 and / or pv =0.35, and / or

[0175] 5. Quantization accuracy of the reference amplitude: Expand its value range. For example, add 5-bit quantization to the parameter value range of the enhanced second-category codebook.

[0176] 6. Quantization accuracy of differential amplitude: Expand its value range. For example, add 4-bit quantization to the parameter value range of the enhanced second-category codebook.

[0177] 7. Phase quantization accuracy: Expand its value range. For example, add 5-bit quantization to the parameter value range of the enhanced second-category codebook.

[0178] Some possible value combinations after the value range is expanded are shown in Table 1 below. The rows with parameter value group index "1, 2, 3" are some possible value combinations after the value range is expanded. The row with parameter value group index "paramCombination-r16=6" is a set of parameters with the best performance corresponding to the enhanced second-category codebook. Simulation results show that expanding the value range of at least one parameter of the enhanced second-category codebook can improve the similarity between the representation of the real CSI and its exact value (for example, the squared generalized cosine similarity SGCS described in Example 1). The simulation results are recorded in the "SGCS of the first spatial layer" column in Table 1 below.

[0179] Table 1

[0180] Some examples of possible value combinations after the value range is expanded can also be shown in Table 2 below.

[0181] Table 2

[0182] The quantization accuracy of the reference amplitude is 4 bits, the quantization accuracy of the differential amplitude is 4 bits, and the quantization accuracy of the phase is 4 bits.

[0183] In some embodiments, expanding the value range of at least one parameter of the enhanced second-category codebook indicating the predicted precoding matrix includes expanding the value range of at least one of the following parameters:

[0184] 1. Value of L: Its value range can be expanded. For example, L=7 and / or L=8 and / or L=9 and / or L=10 can be added to the parameter value range of the enhanced second-category codebook.

[0185] 2. β value: Its value range can be expanded. For example, β = 0.55 or β = 0.6 can be added to the parameter value range of the enhanced second-category codebook.

[0186] 3.p v The value of (v=1,2): Its value range can be expanded. For example, add p to the parameter value range of the enhanced second type codebook. v =0.65 and / or

[0187] 4.p v The value of (v=3,4): Its value range can be expanded. For example, add p to the parameter value range of the enhanced second type codebook. v =0.3 and / or p v =0.35, and / or

[0188] 5. Quantization accuracy of the reference amplitude: Expand its value range. For example, add 5 bits of quantization to the parameter value range of the enhanced second-category codebook for the predicted precoding matrix indication.

[0189] 6. Quantization accuracy of differential amplitude: Expand its value range. For example, add 4-bit quantization to the parameter value range of the enhanced second-category codebook for the predicted precoding matrix indication.

[0190] 7. Phase quantization accuracy: Expand its value range. For example, add 5 bits of quantization to the parameter value range of the enhanced second-category codebook for the predicted precoding matrix indication.

[0191] 8. Q value: Its value range can be expanded. For example, Q=3 is added to the parameter value range of the enhanced second-type codebook indicating the predicted precoding matrix.

[0192] Some possible value combinations after the value range is expanded are shown in Table 3 below. The rows with parameter value group indexes "1, 2, 3" are some possible value combinations after the value range is expanded. The row with parameter value group index "paramCombination-Doppler-r18=9" is the set of parameters with the best performance corresponding to the enhanced second-category codebook. Simulation results show that expanding the value range of at least one parameter of the enhanced second-category codebook can improve the similarity between the representation of the real CSI and its exact value (SGCS described in Example 1). The simulation results are recorded in the "SGCS of the first spatial domain layer" column in the table below.

[0193] Table 3

[0194] Some examples of possible value combinations after the value range is expanded may also be shown in Table 4 below.

[0195] Table 4

[0196] The quantization accuracy of the reference amplitude is 4 bits, the quantization accuracy of the differential amplitude is 4 bits, and the quantization accuracy of the phase is 4 bits.

[0197] In the second embodiment, regarding L, β, p v For the meaning of Q, please refer to related technologies, for example, 3GPP TS 38.214 V18.1.0 (2023-12).

[0198] In some embodiments, for different channel conditions and / or terminal device factors, such as the moving speed of the terminal device, and the scene (indoor, outdoor, urban, suburban), the parameters of the expanded value range are different, and the expanded value range is also different.

[0199] For example, the network device receives the ninth information sent by the terminal device, and the ninth information is used to report the movement information of the terminal device and / or the information of the environment in which the terminal device is located. The network device determines the type of the at least one parameter and / or the value range of the at least one parameter based on the ninth information; or, the ninth information is used to report the information of the type of the at least one parameter and / or the value range of the at least one parameter determined by the terminal device.

[0200] The ninth information is carried by at least one of the following messages and / or resources:

[0201] Terminal equipment auxiliary information (UAI, UE assistant information), newly defined radio resource control (RRC) message, media access control element (MAC CE) signaling, and physical uplink control channel resources similar to scheduling requests (PUCCH SR-like resources).

[0202] According to the second embodiment, the present application can provide a method for receiving data. FIG4 is a schematic diagram of the method, as shown in FIG4 , the method includes:

[0203] Operation 401: Receive first data obtained by a terminal device for artificial intelligence model performance monitoring and / or artificial intelligence model training, wherein the first data represents the data collected by the terminal device in a manner including: using a first method to represent at least a portion of the collected data, wherein the first method is a codebook specified by the Third Generation Partnership Project (3GPP) standardization or a method obtained by expanding the value range of at least one parameter of the codebook specified by the Third Generation Partnership Project (3GPP) standardization.

[0204] In some embodiments, the method further comprises:

[0205] 402. The network device receives ninth information sent by the terminal device.

[0206] For the description of operations 401 and 402 , please refer to the above description of the second embodiment.

[0207] Example 3:

[0208] As shown in FIG3 , the method for receiving data of the present application further includes:

[0209] Operation 303: The network device sends signaling to the terminal device to instruct the terminal device to collect data; or, the network device receives request information from the terminal device, wherein the network device sends the first configuration to the terminal device based on the request information.

[0210] In some embodiments, network device-side AI / ML model monitoring (i.e., data collection by a terminal device) may be triggered by the network device. The network device sends the first configuration, after which the terminal device collects data based on the first configuration and sends the first data. The first configuration is sent via an RRC message.

[0211] In other embodiments, network device-side AI / ML model monitoring (i.e., data collection by the terminal device) may be initiated by the terminal device. The terminal device sends a request to the network device, requesting the network device to perform network device-side AI / ML model monitoring. The reason for the terminal device sending the request may be that the terminal device's bit error rate exceeds a previously set threshold. The network device may send signaling to confirm the terminal device's request and send the first configuration. The terminal device then collects and sends the collected data according to the first configuration. The network device may also send signaling to reject the terminal device's request.

[0212] In some examples, the request information is carried by at least one of the following messages and / or resources: terminal equipment auxiliary information (UAI, UE assistant information), a newly defined radio resource control (RRC) message, a media access control element (MAC CE) signaling, and a physical uplink control channel resource (PUCCH SR-like resource) similar to a scheduling request.

[0213] In some examples, the network device may confirm the terminal device request and send signaling of the first configuration: such as an RRC message.

[0214] In some examples, the network device may also reject the signaling requested by the terminal device: such as RRC message, MAC CE signaling, or DCI signaling.

[0215] According to an embodiment of the first aspect of the present application, the terminal device can be configured, and the terminal device can collect data and send data based on the configuration for artificial intelligence model performance monitoring and / or artificial intelligence model training.

[0216] Embodiments of the second aspect

[0217] The embodiment of the second aspect provides a method for sending data, which is applied to a terminal device, for example, the terminal device 202 in Figure 2. For the parts of the embodiment of the second aspect that are the same as those of the embodiment of the first aspect, reference can be made to the description of the embodiment of the first aspect, which will not be repeated here.

[0218] FIG5 is a schematic diagram of a method for sending data according to an embodiment of the second aspect. The method includes:

[0219] 501. Receive a first configuration sent by a network device, where the first configuration is used to configure the terminal device to obtain first data for artificial intelligence model performance monitoring and / or artificial intelligence model training; and

[0220] 502. Send the first data to the network device.

[0221] In some embodiments, the first configuration includes at least one of the following information:

[0223] Second information, which is used to indicate information about channel state information (CSI) resource settings for data collection by the terminal device;

[0224] third information, which is used to indicate a method for sending the first data;

[0225] fourth information, which is used to indicate a report amount of sending the first data;

[0226] fifth information, which is used to indicate the number of layers or the limit of the number of layers for collecting data;

[0227] sixth information, which is used to indicate how the first data represents the collected data;

[0228] seventh information indicating the amount of collected data; and

[0229] The eighth information is used to indicate frequency domain information of the collected data.

[0230] In some embodiments, the collected data includes at least one of the following data:

[0231] Information of the right singular vectors of the spatial channel matrix, information of the spatial channel matrix.

[0232] In some embodiments, the second information is optional, wherein, if the second information is absent, the terminal device uses information of a channel state information (CSI) resource setting associated with a channel state information (CSI) report configuration for channel measurement; or

[0233] The second information is mandatory, wherein the information of channel state information (CSI) resource setting for channel state information (CSI) reporting and the information of channel state information (CSI) resource setting for data collection indicated by the second information are the same as or different.

[0234] In some embodiments, the time domain characteristics of the channel state information (CSI) resource setting corresponding to the second information and the channel state information (CSI) resource setting used to generate the channel state information (CSI) are the same or different.

[0235] The time domain characteristics of the channel state information (CSI) resource setting corresponding to the second information and the channel state information (CSI) resource setting for generating the channel state information (CSI) are the same or different. The two following embodiments are only examples and are not limited to these two examples. In some embodiments, the channel state information (CSI) resource setting for generating the channel state information (CSI) is aperiodic, and the channel state information (CSI) resource setting corresponding to the second information is aperiodic, semi-persistent, or periodic.

[0236] In some embodiments, the channel state information (CSI) resource setting corresponding to the second information is periodic or semi-continuous, the channel state information (CSI) resource setting for generating the channel state information (CSI) is periodic or semi-continuous, and the period of the first channel state information reference signal (CSI-RS) resource under the channel state information (CSI) resource setting corresponding to the second information configured by the network device and the period of the second channel state information reference signal (CSI-RS) resource under the channel state information (CSI) resource setting for generating the channel state information (CSI) are the same or different.

[0237] In some embodiments, a periodicity of the first channel state information reference signal (CSI-RS) resource is different from a periodicity of the second channel state information reference signal (CSI-RS) resource, and data collection and channel state information (CSI) generation both use the first channel state information reference signal (CSI-RS) resource and the second channel state information reference signal (CSI-RS) resource with a smaller periodicity; or

[0238] The periodicity of the first channel state information reference signal (CSI-RS) resource is shorter than the periodicity of the second channel state information reference signal (CSI-RS) resource; or
