Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a data collection method, a reference signal sending method, a terminal, and a network side device. Background Art

[0002] In the New Radio (NR) system, in order to combat the path loss in high-frequency scenarios, the transmitter and receiver obtain matching beam pairs through beam management (BM) to improve the beamforming gain. In the existing downlink beam management process, the network-side device selects a suitable transmit beam for subsequent communication based on the beam measurement information reported by the terminal, and indicates the selected beam information to the terminal. In order to obtain the optimal beam pair, the network-side device needs to send a channel state information reference signal (CSI-RS) / synchronization signal block (SSB) on all transmit beams (Tx beams), which consumes a lot of reference signal resources; at the same time, the terminal needs to use all receive beams (Rx beams) to measure the CSI-RS / SSB sent on all Tx beams separately, which results in a large measurement overhead.

[0003] In order to solve these problems, it is proposed to use artificial intelligence (AI) / machine learning (ML) technology. Based on the measurement of some beams (pairs) or historical beam (pair) measurement results, the optimal beam (pair) can be predicted, thereby saving reference signal resource overhead, terminal measurement overhead and measurement delay.

[0004] Currently, model training and model inference can be done on the network side or on the terminal side. However, when the model is trained on the terminal side, how to collect beam quality on the terminal side to complete model training / model update / model monitoring is an urgent problem that technicians in this field need to solve.

[0103] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0104] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0105] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0106] In order to facilitate a clearer understanding of the embodiments of the present application, some relevant technical knowledge is first introduced as follows.

[0107] In the existing beam measurement process, the network side device configures the CSI reporting information and the measurement resources associated with it to the terminal through the Radio Resource Control (RRC) signaling. When the content of the CSI report is L1-RSRP or Signal to Interference Noise Ratio (SINR), the terminal reports the index of the best N reference signals in the measurement resource and the corresponding L1-RSRP or L1-SINR, where N is configured by the network side device. From the above process, it can be seen that the existing beam measurement mechanism is that the network side device configures the terminal-level beam measurement reference signal, the terminal measures the reference signal, and feeds back the beam measurement result to the network side device, so that the network side device can select the best downlink transmission beam.

[0108] The 3rd Generation Partnership Project (3GPP) proposed the use of artificial intelligence (AI) / machine learning (ML) technology to predict the optimal beam (pair) based on the measurement of some beams (pairs) or historical beam (pair) measurement results, thereby saving reference signal resource overhead, terminal measurement overhead and measurement delay. Among them, the air interface AI topic uses the following two sub-use cases as sub-use cases of AI beam management:

[0109] Beam management case 1 (BM-case1): Spatial beam prediction, that is, predicting the top-K beams (pairs) in set A (Set A) based on set B (Set B) measured at a certain moment;

[0110] Beam management use case 2 (BM-case2): Time domain beam prediction, that is, predicting the Top-K beams (pairs) of Set A at the next N' moments based on Set B measured at the historical N moments.

[0111] When training an AI / ML model, you need to obtain model input data and label information. Model input information may include:

[0112] (1) Measurement results of Set B beam sets, such as Layer 1 (L1)-Reference Signal Received Power (RSRP). To obtain such data, the network side equipment needs to configure the CSI-RS / SSB resources sent on the beams in Set B, and the terminal performs measurements to obtain the measurement results.

[0113] (2) Downlink transmit Tx or receive beam ID Rx beam ID. The beam set of Set B can be a fixed pattern or selected from a preconfigured pattern or a random pattern. When the beam set of Set B is a preconfigured pattern or a random pattern, using the transmit beam ID Tx beam ID as the model input (for downlink Tx beam prediction) or using the Tx beam ID and Rx beam ID as the model input (for beam pair prediction) can improve the prediction accuracy of the model.

[0114] The output of the AI / ML model can be the identification (ID) of the predicted Top-K beams (pairs) of SetA, or the predicted RSRP of the beams (pairs) of SetA. Regardless of which model output is used as the label, the network-side device needs to configure the CSI-RS / SSB resources sent on the SetA beam set, and the terminal performs measurements. In the implementation process, the quality of the beam refers to the quality of the reference signal sent on the beam (such as the L1-RSRP of the reference signal), and the ID of the beam refers to the index information of the reference signal sent on the beam.

[0115] For BM-Case1 spatial domain beam prediction, the beams in Set B and Set A can be different, for example, the beam in Set B is a narrow beam and the beam in Set A is a wide beam, or the beam in Set B is a subset of the beam in Set A. For BM-Case2 temporal domain beam prediction, in addition to the case where Set B and Set A are respectively wide and narrow beams, or Set B is a subset of Set A, it also includes the case where Set B and Set A are equal.

[0116] At present, 3GPP has discussed the collection method of training data on the terminal side, and believes that network (Network, NW) triggering (option 1) or terminal request (option 2) can be used as potential methods. If the model is trained on the terminal side, data can be collected by the terminal side and the model can be trained by the terminal itself or a third-party (such as a chipset vendor) server. To train the AI / ML model of beam management, the training data includes the quality of the beam, that is, the network side device needs to send a reference signal on the beam, and the terminal measures and obtains the quality of the reference signal (such as layer 1-RSRP). The ability of the terminal side to measure the beam is limited, such as the maximum number of reference signals that the terminal can measure is limited. The terminal needs to collect appropriate data for AI model training / model update, etc. From the perspective of the network side device, it is necessary to send a reference signal for the terminal to collect data. If the beam combinations corresponding to the data collected by each terminal are different, the network side device may need to send reference signals on different beams, and the reference signal overhead is large. At present, there is no existing technology for configuring reference signals for the UE side to collect beam quality, thereby completing model training / model update / model monitoring, etc. There is no specific method for initiating the data collection process, including how the terminal requests and how the network-side equipment cooperates or responds to the terminal's request.

[0117] Figure 1 A flow chart of a data collection method provided in an embodiment of the present application, wherein the method is applied to a terminal, such as Figure 1 As shown, the method comprises the following steps:

[0118] Step 100: According to the reference signal configuration information, measure the reference signal sent by the network side device to obtain the measurement result of the reference signal; the reference signal configuration information is obtained by at least one of the following: receiving the reference signal configuration information sent by the network side device; receiving the reference signal configuration information sent by the network side device based on the indication information of the terminal.

[0119] Specifically, in an embodiment of the present application, after the terminal receives the reference signal configuration information sent by the network side device, it can measure the reference signal sent by the network side device based on the received reference signal configuration information to obtain the reference signal measurement result, and then the collected reference signal measurement result can be used as model training data to perform model training, model update or model monitoring. Among them, the terminal can obtain the reference signal configuration information in a variety of ways; for example, the terminal can directly obtain the reference signal configuration information sent autonomously by the network side device; the terminal can also first send indication information to the network side device, and then receive the reference signal configuration information sent by the network side device based on the terminal's indication information, thereby effectively balancing the reference signal transmission overhead of the network side device and the needs of the terminal.

[0120] According to the data collection method of the embodiment of the present application, after the terminal receives the reference signal configuration information sent by the network side device, it can measure the reference signal based on the reference signal configuration information, and train, update and monitor the model according to the measurement result of the reference signal, so that the network side device does not need to send the reference signal on all transmission beams, and the terminal does not need to measure the reference signal on all beams, thereby realizing the collection of model training data, saving the resource overhead of the reference signal of the network side device, the measurement overhead of the terminal and the terminal measurement delay.

[0121] Optionally, the reference signal configuration information includes at least one of the following:

[0122] Configuration information of reference signals in the first reference signal set; measurement results of reference signals in the first reference signal set are used as model input data for model training, model updating or model monitoring;

[0123] Configuration information of reference signals in the second reference signal set; label information of measurement results of reference signals in the second reference signal set used for model training, model updating or model monitoring;

[0124] a relationship between the first reference signal set and the second reference signal set;

[0125] Pattern information of a first reference signal set.

[0126] Specifically, when training an AI / ML model, it is necessary to obtain model input data and label information. In an embodiment of the present application, the measurement results of the reference signals in the first reference signal set are used as model input data for model training, model update, or model monitoring; the measurement results of the reference signals in the second reference signal set are used as label information for model training, model update, or model monitoring. In the implementation process, the quality of the beam refers to the quality of the reference signal sent on the beam, the first reference signal set represents beam set Set B, and the second reference signal set represents beam set Set A.

[0127] Optionally, the relationship between the first reference signal set and the second reference signal set includes: the first reference signal set is a subset of the second reference signal set, the first reference signal set is equal to the second reference signal set, the beam corresponding to any reference signal in the first reference signal set is different from the beam corresponding to any reference signal in the second reference signal set, and the spatial reception parameter corresponding to any reference signal in the first reference signal set is different from the spatial reception parameter corresponding to any reference signal in the second reference signal set; the pattern information of the first reference signal set is used to indicate the reference signals included in the first reference signal set that the terminal needs to measure. Optionally, when the first reference signal set and the second reference signal set are equal, only the first reference signal set or the second reference signal set may be configured in the reference signal configuration information; when the first reference signal set is a subset of the second reference signal set, the reference signal configuration information may not carry the configuration information of the reference signals in the first reference signal set and the pattern information of the first reference signal set, and the terminal can determine the reference signals to be measured in the first reference signal set according to the measurement results of the reference signals in the second reference signal set, so that the terminal can flexibly obtain the configuration information of the reference signals to be measured in a variety of ways.

[0128] In the data collection method of the embodiment of the present application, the reference signal configuration information includes one or more of the configuration information of the reference signals in the first reference signal set, the configuration information of the reference signals in the second reference signal set, the relationship between the first reference signal set and the second reference signal set, and the pattern information of the first reference signal set, so that the terminal can flexibly obtain the configuration information of the reference signals required for measurement in a variety of ways, and then can collect the input data and label information required for model training to complete the training, monitoring and updating of the terminal side model.

[0129] Optionally, the configuration information includes at least one of the following:

[0130] The time domain information, frequency domain information, sequence information and power information of the reference signal.

[0131] Specifically, in an embodiment of the present application, the time domain information, frequency domain information, sequence information and power information of the reference signal to be measured are indicated to the terminal through the configuration information of the reference signal in the first reference signal set and the configuration information of the reference signal in the second reference signal set, so that the terminal can accurately measure the reference signal based on the configuration information to obtain the measurement result of the reference signal and train, update or monitor the model.

[0132] Optionally, receiving reference signal configuration information sent by a network side device includes:

[0133] Receive a system message sent by a network side device; the system message carries reference signal configuration information.

[0134] Specifically, in an embodiment of the present application, the network side device can autonomously send reference signal configuration information to the terminal, and the terminal can directly obtain the reference signal configuration information and measure the reference signal. Optionally, the network side device can broadcast the reference signal configuration information to each terminal through a system message, that is, the network side device autonomously determines the reference signal configuration and provides the same reference signal configuration information to all terminals. After the terminal receives the reference signal configuration information carried in the system message, it can measure the reference signal on demand to collect data and train the model. In the above method, the network side device carries the reference signal configuration information based on the system message, the implementation method is simple, the configuration efficiency of the reference signal is higher, and the overhead of signaling resources and the transmission overhead of the reference signal are effectively saved.

[0135] Figure 2 A flow chart of a data collection method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0136] Step 200: The network side device sends a system message to the terminal, where the system message carries reference signal configuration information used by the terminal to collect training data; wherein the reference signal configuration information includes:

[0137] (1) Configuration information of reference signals in the first reference signal set (Set B beam set) for the AI-based beam management model (such as time domain, frequency domain, sequence, power, etc.).

[0138] For example, the first reference signal set: {CSI-RS reference signal 9, CSI-RS reference signal 13, CSI-RS reference signal 18, CSI-RS reference signal 22}.

[0139] (2) Configuration information of reference signals in the second reference signal set (Set A beam set) for the AI-based beam management model (such as time domain, frequency domain, sequence, power, etc.).

[0140] For example, the second reference signal set: {CSI-RS reference signal 0, CSI-RS reference signal 1, …, CSI-RS reference signal 31}, and time domain and frequency domain information of CSI-RS reference signal 0 to CSI-RS reference signal 31.

[0141] (3) A relationship between the first reference signal set (Set B beam set) and / or the second reference signal set (Set A beam set), such as a subset relationship, an equal relationship, or a different relationship.

[0142] For example, the first reference signal set and the second reference signal set are in a subset relationship.

[0143] (4) Pattern information of the first reference signal set: When the first reference signal set is a subset of the second reference signal set, the pattern information of the first reference signal set is used to indicate which reference signals in the second reference signal set are reference signals in the first reference signal set that the terminal needs to measure.

[0144] Among them, when the first reference signal set is equal to the second reference signal set, or the first reference signal set is a subset of the second reference signal set, the configuration information of the reference signals in the first reference signal set and the pattern information of the first reference signal set are optional, that is, the network side device can only configure the configuration information of the reference signals in the second reference signal set, and the terminal can select the pattern of the first reference signal set from the second reference signal set. For example, the terminal selects the reference signals whose L1-RSRP is greater than the threshold in the second reference signal set to form the first reference signal set.

[0145] Step 201: The network side device sends a reference signal to the terminal;

[0146] Step 202: Each terminal measures the reference signal as required according to the reference signal configuration information obtained in step 200. When the terminal has a model training or model update requirement, the terminal receives the reference signal according to the reference signal configuration information in step 200, otherwise the terminal does not receive the reference signal.

[0147] Repeat steps 201-202 until the terminal collects enough data according to its own needs, and then perform model training or model update based on the collected data.

[0148] For example, the terminal receives a system message, receives CSI-RS reference signal 0 to CSI-RS reference signal 31 according to the received reference signal configuration information, and stops receiving the above reference signals after collecting a certain amount of data (such as 30,000 data samples). The L1-RSRP of {CSI-RS reference signal 9, CSI-RS reference signal 13, CSI-RS reference signal 18, CSI-RS reference signal 22} in these 30,000 samples is used as the model input, and the L1-RSRP of {CSI-RS reference signal 0, CSI-RS reference signal 1, ..., CSI-RS reference signal 31} is used as the model output to train the AI ​​model, which can predict the optimal beam of the entire set of 32 beams based on the beam quality of the 4 subset beams.

[0149] In the data collection method of the embodiment of the present application, the network side device provides the same reference signal configuration information to all terminals through system messages, and the terminals measure the reference signals on demand to collect training data and train the model. The implementation method is simple and the configuration efficiency of the reference signal is higher, which effectively saves the overhead of signaling resources and the transmission overhead of the reference signal.

[0150] Optionally, receiving reference signal configuration information sent by a network side device based on indication information of a terminal includes:

[0151] Receive multiple reference signal configuration information sent by network side equipment;

[0152] Selecting at least one reference signal configuration information from a plurality of reference signal configuration information;

[0153] Sending indication information to a network side device, where the indication information is used to indicate at least one reference signal configuration information selected by the terminal;

[0154] Receive reference signal configuration information sent by a network side device based on the indication information of the terminal.

[0155] Specifically, in the embodiment of the present application, after the terminal receives multiple reference signal configuration information sent by the network side device, the terminal can select at least one reference signal configuration information from the multiple reference signal configuration information sent by the network side device based on its own measurement capability and model training / update requirements and feed it back to the network side device. After the network side device receives the feedback information sent by the terminal, it can send the corresponding reference signal configuration information to the terminal according to the selection of the terminal.

[0156] Figure 3 A flow chart of a data collection method provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method comprises the following steps:

[0157] Step 300: The network side device sends supported multiple reference signal configuration information to each terminal.

[0158] For example, the network side device supports reference signal configuration #1 and reference signal configuration #2.

[0159] Among them, reference signal configuration #1:

[0160] The second reference signal set: {CSI-RS reference signal 0, CSI-RS reference signal 1, ..., CSI-RS reference signal 31}, and time domain and frequency domain information of CSI-RS reference signal 0 to CSI-RS reference signal 31.

[0161] The first reference signal set and the second reference signal set are in a subset relationship;

[0162] The first reference signal set: {CSI-RS reference signal 9, CSI-RS reference signal 13, CSI-RS reference signal 18, CSI-RS reference signal 22}.

[0163] Reference signal configuration #2:

[0164] Second reference signal set: {CSI-RS reference signal 0, CSI-RS reference signal 1, ..., CSI-RS reference signal 31};

[0165] The first reference signal set is different from the second reference signal set;

[0166] The first reference signal set: {SSB reference signal 0, SSB reference signal 1, …, SSB reference signal 7}.

[0167] Step 301: The terminal feeds back selected reference signal configuration information to a network side device.

[0168] For example, terminal 1 selects reference signal configuration #1, and terminal 2 can train an AI model to predict 32 beams based on 8 wide beams and select reference signal configuration #2.

[0169] Step 302: After receiving the feedback from the terminal, the network side device sends a response to the terminal, wherein the response information may be an activation signaling.

[0170] For example, the network side device sends activation information of reference signal configuration #1 to terminal 1, and sends activation information of reference signal configuration #2 to terminal 2.

[0171] Step 303: The network-side device sends a reference signal corresponding to reference signal configuration #1 to terminal 1, and sends a reference signal corresponding to reference signal configuration #2 to terminal 2.

[0172] Step 304: The terminal measures the reference signal based on the received reference signal configuration information to obtain a reference signal measurement result.

[0173] Steps 303 to 304 are repeated until the terminal collects enough data.

[0174] For example, terminal 2 receives the reference signal according to reference signal configuration #2, and after collecting a certain amount of data (such as 30,000 data samples), sends a data collection stop signaling to the network side device. The network side device deactivates reference signal configuration #2. Each sample includes the L1-RSRP of {SSB reference signal 0, SSB reference signal 1, ..., SSB reference signal 7} and the L1-RSRP of {CSI-RS reference signal 0, CSI-RS reference signal 1, ..., CSI-RS reference signal 31}. The terminal uses the L1-RSRP of {SSB reference signal 0, SSB reference signal 1, ..., SSB reference signal 7} in these 30,000 samples as model input and the L1-RSRP of {CSI-RS reference signal 0, CSI-RS reference signal 1, ..., CSI-RS reference signal 31} as model output to train the AI ​​model, which can predict the optimal beam in the 32 CSI-RS beam set based on the beam quality of 8 SSB beams.

[0175] Step 305: The terminal sends a data collection stop signaling to the network side device.

[0176] Step 306: After receiving the data collection stop signaling sent by the terminal, the network side device deactivates the corresponding reference signal configuration information and stops sending the reference signal.

[0177] The terminal performs model training or model update based on the collected data.

[0178] In the data collection method of the embodiment of the present application, after the terminal receives the multiple reference signal configuration information sent by the network side device, the terminal can select the appropriate reference signal configuration information according to its own situation and feed it back to the network side device, and the network side device can also send the corresponding reference signal to the terminal according to the terminal's selection. That is, different terminals can select the reference signal configuration information suitable for their own capabilities and model training / model update requirements from the multiple reference signal configuration information provided by the network side device. The configuration result of the reference signal is jointly determined by the network side device and the terminal, which effectively balances the reference signal transmission overhead and the terminal's needs.

[0179] Optionally, receiving reference signal configuration information sent by a network side device based on indication information of a terminal includes:

[0180] Sending indication information to the network side device; the indication information is used to indicate the reference signal configuration information requested by the terminal;

[0181] Receive reference signal configuration information sent by a network side device based on the indication information of the terminal.

[0182] Specifically, in an embodiment of the present application, the terminal first sends indication information to the network side device to indicate the reference signal configuration information requested by the terminal to the network side device. After the network side device learns the reference signal configuration information requested by the terminal, it can send the reference signal configuration information to the terminal based on the request of the terminal. Optionally, since the network side device needs to balance the requests of multiple terminals and the reference signal transmission overhead, the reference signal configuration information provided by the network side device to the terminal can be the same as the reference signal configuration information requested by the terminal, or can be different from the reference signal configuration information requested by the terminal (such as the reference signal period, the length of the transmission window), thereby effectively balancing the reference signal transmission overhead of the network side device and the needs of the terminal.

[0183] Figure 4 A flow chart of a data collection method provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method comprises the following steps:

[0184] Step 400: The terminal sends reference signal configuration request information to the network side device, including:

[0185] (1) Configuration information of reference signals in the first reference signal set (Set B beam set) for the AI-based beam management model (such as time domain, frequency domain, sequence, and power-related information);

[0186] (2) Configuration information of reference signals in the second reference signal set (Set A beam set) for the AI-based beam management model (such as time domain, frequency domain, sequence, and power-related information);

[0187] (3) a relationship between the first reference signal set and / or the second reference signal set, such as a subset relationship, an equal relationship, or a different relationship;

[0188] Alternatively, the information includes an identifier of an AI / ML model (such as a model ID) or an identifier of an AI / ML function (such as a functionality ID) or a dataset identifier (dataset ID), which is used to indicate that the terminal requests a reference signal corresponding to the model ID or functionality ID or dataset ID. In addition, the terminal may also carry the purpose of requesting a reference signal in the request information. For example, if the terminal requests a reference signal for model training and carries model ID#5, it indicates that the terminal requests the same reference signal configuration information as the training dataset of model ID#5.

[0189] For example, the terminal needs to update the AI / ML model corresponding to model ID#5. The terminal sends a data collection request signaling to the network side device, and the data collection request signaling carries the model identifier (model ID#5).

[0190] After the terminal accesses the cell, it has informed the network side of the application conditions of device model ID#5 through the model registration or model identification process, including:

[0191] The first reference signal set and the second reference signal set are in a subset relationship;

[0192] The first reference signal set includes 4 reference signals;

[0193] The second reference signal set includes 32 reference signals.

[0194] Step 401: After receiving the request information from the terminal, the network device sends reference signal configuration information to the terminal. The reference signal configuration information sent by the network device may be different from the configuration information requested by the terminal, such as the network device sends more preferred reference signal configuration information according to the current network status.

[0195] For example, the network side device sends the reference signal configuration information to the terminal according to the above application conditions during model registration or model identification of model ID#5.

[0196] Step 402: The network side device sends a reference signal to the terminal.

[0197] Step 403: The terminal measures the reference signal according to the received reference signal configuration information.

[0198] Repeat steps 402 to 403 until the terminal collects enough data.

[0199] Step 404: The terminal sends a data collection stop signaling to the network side device.

[0200] For example, the terminal receives the reference signal according to the reference signal configuration information, and after collecting a certain amount of data (such as 5000 data samples), sends a data collection stop signaling to the network side device. The network side device sends a confirmation message to the terminal, and the confirmation message may be a signaling for releasing the above reference signal configuration, indicating that the network side device no longer sends the reference signal corresponding to the above configuration information.

[0201] Step 405: After receiving the data collection stop signaling sent by the terminal, the network side device sends a response message or confirmation message of the terminal data collection signaling to the terminal. The terminal performs model training or model update according to the collected data.

[0202] For example, the terminal updates the AI / ML model of model ID #5 based on the 5,000 data samples collected. The updated model is more suitable for the current channel environment and improves the performance of the model.

[0203] In the data collection method of the embodiment of the present application, the terminal informs the network side device of its reference signal configuration requirements, and the network side device sends the final reference signal configuration information to the terminal based on the requirements of each terminal and the reference signal overhead, thereby effectively balancing the reference signal sending overhead of the network side device and the requirements of the terminal.

[0204] Optionally, the indication information includes at least one of the following:

[0205] the number of reference signals in the first reference signal set;

[0206] the number of reference signals in the second reference signal set;

[0207] a relationship between the first reference signal set and the second reference signal set;

[0208] The identification of the model;

[0209] Identification of model functionality;

[0210] Dataset identifier;

[0211] The requested data volume or the reference signal sending window duration;

[0212] The reason for the request or the purpose of the request.

[0213] Specifically, in an embodiment of the present application, the terminal can inform the network side device of its own reference signal configuration requirements in a displayed manner. For example, the request information of the reference signal configuration information sent by the terminal to the network side device includes at least one of the following: the number of reference signals in the first reference signal set, the number of reference signals in the second reference signal set and the relationship between the first reference signal set and the second reference signal set, the period of the reference signal corresponding to the first reference signal set and / or the second reference signal set (the terminal can determine the transmission period according to its own moving speed), the first reference signal set and / or the reference signal corresponding to the first reference signal set. The amount of data or the reference signal transmission window duration. Optionally, the terminal can also inform the network side device of its own reference signal configuration requirements in an implicit manner. For example, the request information of the reference signal configuration information sent by the terminal to the network side device includes at least one of the following: the identification of the model, the identification of the model function, the data set identification, the requested amount of data or the reference signal transmission window duration and the request reason or request purpose, which is used to indicate that the terminal requests the reference signal corresponding to the identification model ID of the model or the identification functionality ID of the model function or the identification dataset ID.

[0214] In the data collection method of the embodiment of the present application, the terminal can inform the network side device of its reference signal configuration requirements in an explicit or implicit manner, and the implementation method is flexible and diverse.

[0215] Optionally, receiving reference signal configuration information sent by a network side device based on indication information of a terminal includes:

[0216] A radio resource control RRC message sent by a network side device is received; the RRC message carries reference signal configuration information.

[0217] Specifically, in an embodiment of the present application, after the terminal indicates the reference signal configuration information requested by the terminal to the network side device, the terminal can obtain the reference signal configuration information sent by the network side device based on the indication information of the terminal. Optionally, the network side device can send a radio resource control RRC message to the terminal, and carry the reference signal configuration information in the RRC message.

[0218] In the data collection method of the embodiment of the present application, the network side device carries the reference signal configuration information based on the existing radio resource control RRC message, which is simple to implement and saves the overhead of signaling resources.

[0219] Optionally, after obtaining the measurement result of the reference signal, the method further includes:

[0220] Sending first information to a network side device; the first information is used to request to stop sending a reference signal or to deactivate reference signal configuration information;

[0221] Receive second information sent by the network side device; the second information is used to instruct the network side device to deactivate the reference signal configuration information or the terminal to stop receiving the reference signal.

[0222] Specifically, in an embodiment of the present application, after the terminal obtains the measurement result of the reference signal, that is, after the terminal completes the collection of training data, the terminal can send a first message to the network side device to inform the network side device that the data collection has been completed, and request the network side device to stop sending the reference signal or the network side device to deactivate the reference signal configuration information. After the network side device receives the first message sent by the terminal, it can also be known that the terminal has completed the collection of training data, and the network side device can instruct the terminal to deactivate the reference signal configuration information or the terminal to stop receiving the reference signal. Optionally, the network side device can also send a timer to the terminal to inform the terminal to deactivate the reference signal configuration information or the terminal to stop receiving the reference signal after the timer expires.

[0223] In the data collection method of the embodiment of the present application, the terminal notifies the network side device that the terminal has completed the collection of training data, and the network side device can promptly deactivate the reference signal configuration information or stop sending the reference signal, thereby effectively saving the reference signal sending overhead.

[0224] Figure 5 A schematic diagram of a reference signal sending method provided in an embodiment of the present application, wherein the method is applied to a network side device, such as Figure 5 As shown, the method comprises the following steps:

For example, the network side device can directly send the reference signal configuration information to the terminal; the network side device can also send the reference signal configuration information to the terminal based on the indication information sent by the terminal.

[0227] Step 501: Send a reference signal to a terminal based on reference signal configuration information; the reference signal is used by the terminal to measure the reference signal to obtain a measurement result of the reference signal.

[0228] Specifically, after the network side device sends the reference signal configuration information to the terminal, it can send the reference signal based on the reference signal configuration information. The terminal can also measure the reference signal according to the received reference signal configuration information and obtain the reference signal measurement result to train, update and monitor the model.

[0229] In the reference signal sending method of the embodiment of the present application, the network side device can directly send the reference signal configuration information to the terminal, or send the reference signal configuration information to the terminal based on the indication information of the terminal, which effectively balances the reference signal sending overhead of the network side device and the needs of the terminal. In addition, after the network side device sends the reference signal configuration information to the terminal, the network side device can send the reference signal according to the reference signal configuration information, and the terminal can also measure the reference signal according to the received reference signal configuration information and obtain the measurement result of the reference signal to train, update and monitor the model, so that the network side device does not need to send the reference signal on all transmission beams, and the terminal does not need to measure the reference signal on all beams, thereby realizing the collection of model training data, saving the resource overhead of the reference signal of the network side device, the measurement overhead of the terminal and the measurement delay of the terminal.

Optionally, when the first reference signal set and the second reference signal set are equal, only the first reference signal set or the second reference signal set may be configured in the reference signal configuration information; when the first reference signal set is a subset of the second reference signal set, the reference signal configuration information may not carry the configuration information of the reference signals in the first reference signal set and the pattern information of the first reference signal set, and the terminal can determine the reference signals to be measured in the first reference signal set according to the measurement results of the reference signals in the second reference signal set, so that the terminal can flexibly obtain the configuration information of the reference signals to be measured in a variety of ways.
