[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202311255282.5, filed on September 26, 2023, entitled “Data Collection Method, Reference Signal Transmission Method, Terminal and Network Side Device,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of wireless communication technologies, and in particular to a data collection method, a reference signal sending method, a terminal, and a network-side device. Background Art

[0004] 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 the 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.

[0005] To address these issues, artificial intelligence (AI) / machine learning (ML) technology has been proposed. 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.

[0006] Currently, model training and inference can be performed on both network-side devices and terminal devices. However, when training models on the terminal side, how to collect beam quality data on the terminal side to complete model training, model updates, and model monitoring is an urgent problem that technicians in this field need to solve.

[0106] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0107] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0108] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0109] In order to facilitate a clearer understanding of the various embodiments of the present disclosure, some relevant technical knowledge is first introduced as follows.

[0110] In the existing beam measurement process, the network-side device configures CSI reporting information and associated measurement resources for the terminal through Radio Resource Control (RRC) signaling. When the CSI reporting content is L1-RSRP or Signal to Interference Noise Ratio (SINR), the terminal reports the indexes of the best N reference signals in the measurement resources 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 results to the network-side device, so that the network-side device can select the optimal downlink transmit beam.

[0111] The 3rd Generation Partnership Project (3GPP) has proposed using artificial intelligence (AI) / machine learning (ML) technology to predict the optimal beam (pair) based on measurements of some beams (pairs) or historical beam (pair) measurements, thereby saving reference signal resource overhead, terminal measurement overhead, and measurement latency. The air interface AI project identifies the following two sub-use cases as sub-use cases for AI beam management:

[0112] Beam Management Case 1 (BM-case 1): Spatial beam prediction, which predicts the top-K beams (pairs) in Set A based on Set B measured at a specific moment.

[0113] Beam management use case 2 (BM-case 2): Time-domain beam prediction, that is, predicting the top-K beams (pairs) of Set A at the next N' time points based on Set B measured at the past N time points.

[0114] When training an AI / ML model, you need to obtain input data and label information. Model input information may include:

[0115] (1) Measurement results of Set B beams, such as Layer 1 (L1) Reference Signal Received Power (RSRP). To obtain this data, the network must configure the CSI-RS / SSB resources transmitted on the beams in Set B, and the terminal must perform the measurement to obtain the measurement results.

[0116] (2) Downlink transmit or receive beam ID. The beam set of Set B can be a fixed pattern, 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 as the model input (for downlink Tx beam prediction) or using both the Tx beam ID and the Rx beam ID as the model input (for beam pair prediction) can improve the model's prediction accuracy.

[0117] The output of the AI / ML model can be the identification (ID) of the predicted Top-K beams (pairs) of SetA or the RSRP of the predicted 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 the measurement. 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 beam ID refers to the index information of the reference signal sent on the beam.

[0118] For BM-Case1 spatial beam prediction, the beams in Set B and Set A can be different. For example, the beam in Set B can be narrow and the beam in Set A can be wide. Alternatively, the beam in Set B can be a subset of the beam in Set A. For BM-Case2 temporal beam prediction, in addition to the cases where Set B and Set A are respectively wide and narrow beams, or Set B is a subset of Set A, Set B and Set A can also be equal.

[0119] 3GPP is currently discussing methods for collecting training data on the terminal side, considering network (NW) triggering (Option 1) or terminal request (Option 2) as potential methods. If model training occurs on the terminal side, data can be collected by the terminal itself or by a third-party server (such as a chipset vendor) to train the model. To train AI / ML models for beam management, the training data includes beam quality. This requires network equipment to transmit reference signals on beams, and the terminal to measure and obtain reference signal quality (such as Layer 1 RSRP). The terminal's ability to measure beams is limited, such as the maximum number of reference signals that the terminal can measure. The terminal needs to collect appropriate data for AI model training / model updates. From the perspective of network equipment, reference signals need to be transmitted for terminal data collection. If the data collected by each terminal corresponds to different beam combinations, the network equipment may need to transmit reference signals on different beams, resulting in high reference signal overhead. Currently, there is no existing technology for configuring reference signals for UE-side beam quality monitoring to facilitate model training / model updates / model monitoring. 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.

[0120] FIG1 is a flow chart of a data collection method provided by an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG1 , the method includes the following steps:

[0121] Step 100: Measure a reference signal sent by a network-side device according to reference signal configuration information to obtain a reference signal measurement result; the reference signal configuration information is obtained by at least one of the following: receiving reference signal configuration information sent by a network-side device; receiving reference signal configuration information sent by a network-side device based on indication information of a terminal.

[0122] Specifically, in the embodiment of the present disclosure, 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. It should be noted that since model monitoring judges the performance of the model based on the monitoring results over a period of time, model monitoring can be understood or replaced by performance 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.

[0123] According to the data collection method of the embodiment of the present disclosure, 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. In this way, the network side device does not need to send the reference signal on all transmit 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.

[0124] Optionally, the reference signal configuration information includes at least one of the following:

[0125] Configuration information of reference signals in the first reference signal set; measurement results of the reference signals in the first reference signal set are used as input data for model training, model updating, or model monitoring;

[0126] 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;

[0127] a relationship between the first reference signal set and the second reference signal set;

[0128] Pattern information of the first reference signal set.

[0129] Specifically, when training an AI / ML model, it is necessary to obtain input data and label information. In the disclosed embodiment, the measurement results of the reference signals in the first reference signal set are used as 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.

[0130] 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 parameters corresponding to any reference signal in the first reference signal set are different from the spatial reception parameters corresponding to any reference signal in the second reference signal set; and 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, the reference signal configuration information may only configure the first reference signal set or the second reference signal set; 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. The terminal can independently determine the reference signals to be measured in the first reference signal set based on the measurement results of the reference signals in the second reference signal set, thereby allowing the terminal to flexibly obtain the configuration information of the reference signals to be measured in a variety of ways.

[0131] In the data collection method of the embodiment of the present disclosure, 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 thus can collect the input data and label information required for model training to complete the training, monitoring and updating of the terminal-side model.

[0132] Optionally, the configuration information includes at least one of the following:

[0133] Time domain information, frequency domain information, sequence information and power information of the reference signal.

[0134] Specifically, in the embodiment of the present disclosure, 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.

[0135] Optionally, receiving reference signal configuration information sent by a network-side device includes:

[0136] Receive a system message sent by a network-side device; the system message carries reference signal configuration information.

[0137] Specifically, in an embodiment of the present disclosure, 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.

[0138] FIG2 is a flow chart of a data collection method provided by an embodiment of the present disclosure. As shown in FIG2 , the method includes the following steps:

[0139] Step 200: The network-side device sends a system message to the terminal. The system message carries reference signal configuration information used by the terminal for training data collection. The reference signal configuration information includes:

[0140] (1) Configuration information of the 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.).

[0141] 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}.

[0142] (2) Configuration information of the reference signals in the second reference signal set (Set A beam set) used for the AI-based beam management model (such as time domain, frequency domain, sequence, power, etc.).

[0143] 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.

[0144] (3) The 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.

[0145] For example, the first reference signal set and the second reference signal set are in a subset relationship.

[0146] (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.

[0147] 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 independently select the pattern of the first reference signal set from the second reference signal set. For example, the terminal selects reference signals in the second reference signal set whose L1-RSRP is greater than a threshold to form the first reference signal set.

[0148] Step 201: The network side device sends a reference signal to the terminal;

[0149] In step 202, each terminal measures the reference signal as needed according to the reference signal configuration information obtained in step 200. When a terminal has a model training or model update requirement, it receives the reference signal according to the reference signal configuration information in step 200; otherwise, the terminal does not receive the reference signal.

[0150] 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.

[0151] For example, a terminal receives a system message and, based on the received reference signal configuration information, receives CSI-RS reference signals 0 through 31. After collecting a certain amount of data (e.g., 30,000 data samples), it stops receiving these reference signals. 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 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 model output to train an AI model. This model can predict the optimal beam for the full set of 32 beams based on the beam quality of the four subset beams.

[0152] In the data collection method of the embodiment of the present disclosure, the network-side device provides the same reference signal configuration information to all terminals through system messages. The terminals measure the reference signals on demand to collect training data and train the model. The implementation 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.

[0153] Optionally, receiving reference signal configuration information sent by a network-side device based on indication information of a terminal includes:

[0154] Receive multiple reference signal configuration information sent by network side equipment;

[0155] Selecting at least one reference signal configuration information from a plurality of reference signal configuration information;

[0156] 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;

[0157] Receive reference signal configuration information sent by a network-side device based on the indication information of the terminal.

[0158] Specifically, in an embodiment of the present disclosure, after a terminal receives multiple types of reference signal configuration information sent by a network device, the terminal may select at least one type of reference signal configuration information from the multiple types of reference signal configuration information sent by the network device based on its own measurement capabilities and model training / update requirements, and feed the selected type of reference signal configuration information back to the network device. After receiving the feedback information sent by the terminal, the network device may send the corresponding reference signal configuration information to the terminal based on the terminal's selection.

[0159] FIG3 is a flow chart of a data collection method provided by an embodiment of the present disclosure. As shown in FIG3 , the method includes the following steps:

[0160] Step 300: The network-side device sends supported multiple reference signal configuration information to each terminal.

[0161] For example, the network-side device supports reference signal configuration #1 and reference signal configuration #2.

[0162] Among them, reference signal configuration #1:

[0163] The second reference signal set includes {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.

[0164] The first reference signal set and the second reference signal set are in a subset relationship;

[0165] First reference signal set: {CSI-RS reference signal 9, CSI-RS reference signal 13, CSI-RS reference signal 18, CSI-RS reference signal 22}.

[0166] Reference Signal Configuration #2:

[0167] Second reference signal set: {CSI-RS reference signal 0, CSI-RS reference signal 1, ..., CSI-RS reference signal 31};

[0168] The first reference signal set is different from the second reference signal set;

[0169] First reference signal set: {SSB reference signal 0, SSB reference signal 1, ..., SSB reference signal 7}.

[0170] Step 301: The terminal feeds back selected reference signal configuration information to the network side device.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] Step 304: The terminal measures the reference signal based on the received reference signal configuration information to obtain a reference signal measurement result.

[0176] Repeat steps 303 to 304 until the terminal collects enough data.

[0177] For example, Terminal 2 receives reference signals according to Reference Signal Configuration #2. After collecting a certain amount of data (e.g., 30,000 data samples), it sends a data collection stop signaling to the network device. The network 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 an AI model. This model can predict the optimal beam in a set of 32 CSI-RS beams based on the beam quality of 8 SSB beams.

[0178] Step 305: The terminal sends a data collection stop signaling to the network side device.

[0179] 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.

[0180] The terminal performs model training or model update based on the collected data.

[0181] In the data collection method of the disclosed embodiments, after a terminal receives multiple reference signal configuration information sent by a network device, it can select the appropriate reference signal configuration information based on its own circumstances and feedback it to the network device. The network device can then send the corresponding reference signal to the terminal based on the terminal's selection. In other words, different terminals can select the reference signal configuration information that suits their capabilities and model training / model update requirements from the multiple reference signal configuration information provided by the network device. The reference signal configuration result is jointly determined by the network device and the terminal, effectively balancing the reference signal transmission overhead and the terminal's needs.

[0182] Optionally, receiving reference signal configuration information sent by a network-side device based on indication information of a terminal includes:

[0183] Sending indication information to the network side device; the indication information is used to indicate the reference signal configuration information requested by the terminal;

[0184] Receive reference signal configuration information sent by a network-side device based on the indication information of the terminal.

[0185] Specifically, in an embodiment of the present disclosure, the terminal first sends indication information to the network-side device to indicate the reference signal configuration information requested by the terminal. 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 terminal's request. 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.

[0186] FIG4 is a flow chart of a data collection method provided by an embodiment of the present disclosure. As shown in FIG4 , the method includes the following steps:

[0187] Step 400: The terminal sends reference signal configuration request information to the network side device, including:

[0188] (1) Configuration information of reference signals in the first reference signal set (Set B beam set) used in the AI-based beam management model (e.g., time domain, frequency domain, sequence, and power-related information);

[0189] (2) Configuration information of reference signals in the second reference signal set (Set A beam set) used in the AI-based beam management model (e.g., time domain, frequency domain, sequence, and power-related information);

[0190] (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;

[0191] Alternatively, the information includes an identifier of an AI / ML model (e.g., a model ID), an identifier of an AI / ML function (e.g., a functionality ID), or a dataset ID, indicating that the terminal is requesting a reference signal corresponding to the model ID, functionality ID, or dataset ID. Furthermore, the terminal may also include the purpose of requesting a reference signal in the request information. For example, if the terminal requests a reference signal for model training and also includes model ID #5, it indicates that the terminal is requesting the same reference signal configuration information as the training dataset for model ID #5.

[0192] 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).

[0193] After the terminal accesses the cell, it informs the network side of the application conditions of device model ID #5 through the model registration or model identification process, including:

[0194] The first reference signal set and the second reference signal set are in a subset relationship;

[0195] The first reference signal set includes 4 reference signals;

[0196] The second reference signal set includes 32 reference signals.

[0197] 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, for example, the network device sends more preferred reference signal configuration information based on the current network status.

[0198] 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.

[0199] Step 402: The network-side device sends a reference signal to the terminal.

[0200] Step 403: The terminal measures the reference signal according to the received reference signal configuration information.

[0201] Repeat steps 402 to 403 until the terminal collects enough data.

[0202] Step 404: The terminal sends a data collection stop signaling to the network side device.

[0203] For example, the terminal receives reference signals according to the reference signal configuration information, and after collecting a certain amount of data (e.g., 5000 data samples), sends data collection stop signaling to the network device. The network device sends a confirmation message to the terminal, which may be a signaling to release the reference signal configuration, indicating that the network device will no longer send the reference signal corresponding to the configuration information.

[0204] 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 based on the collected data.

[0205] For example, the terminal updates the AI / ML model with model ID #5 based on 5,000 collected data samples. The updated model is more suitable for the current channel environment and improves model performance.

[0206] In the data collection method of the embodiment of the present disclosure, the terminal informs the network side device of its own reference signal configuration requirements. 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, effectively balancing the reference signal transmission overhead of the network side device and the requirements of the terminal.

[0207] Optionally, the instruction information includes at least one of the following:

[0208] the number of reference signals in the first reference signal set;

[0209] the number of reference signals in the second reference signal set;

[0210] a relationship between the first reference signal set and the second reference signal set;

[0211] The identification of the model;

[0212] Identification of the model's functionality;

[0213] Dataset identifier;

[0214] Requested data volume or reference signal sending window duration;

[0215] The reason or purpose of the request.

[0216] Specifically, in an embodiment of the present disclosure, a terminal may notify a network device of its own reference signal configuration requirements in an explicit manner. For example, the reference signal configuration information request information sent by the terminal to the network 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 signals corresponding to the first reference signal set and / or the second reference signal set (the terminal may determine the transmission period based on its own mobile speed), the data volume of the first reference signal set and / or the reference signals corresponding to the first reference signal set, or the reference signal transmission window duration. Optionally, the terminal may also notify the network device of its own reference signal configuration requirements in an implicit manner. For example, the reference signal configuration information request information sent by the terminal to the network device includes at least one of the following: a model identifier, a model function identifier, a dataset identifier, the requested data volume or reference signal transmission window duration, and a request reason or request purpose, indicating that the terminal is requesting a reference signal corresponding to the model ID, the model function identifier, or the dataset ID.

[0217] According to the data collection method of the embodiment of the present disclosure, the terminal can inform the network side device of its own reference signal configuration requirements in an explicit or implicit manner, and the implementation method is flexible and diverse.

[0218] Optionally, receiving reference signal configuration information sent by a network-side device based on indication information of a terminal includes:

[0219] Receive a radio resource control (RRC) message sent by a network-side device; the RRC message carries reference signal configuration information.

[0220] Specifically, in an embodiment of the present disclosure, after the terminal indicates the reference signal configuration information requested by the terminal to the network device, the terminal can obtain the reference signal configuration information sent by the network device based on the terminal's indication information. Optionally, the network device can send a radio resource control (RRC) message to the terminal, and the RRC message can carry the reference signal configuration information.

[0221] In the data collection method of the embodiment of the present disclosure, 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.

[0222] Optionally, after obtaining the measurement result of the reference signal, the method further includes:

[0223] Sending first information to a network side device; the first information is used to request to stop reference signal transmission or deactivate reference signal configuration information;

[0224] 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.

[0225] Specifically, in an embodiment of the present disclosure, 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.

[0226] In the data collection method of the embodiment of the present disclosure, 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, effectively saving the reference signal sending overhead.

[0227] FIG5 is a flow chart of a reference signal transmission method according to an embodiment of the present disclosure. The method is applied to a network-side device. As shown in FIG5 , the method includes the following steps:

[0228] Step 500: Send reference signal configuration information to the terminal; or, send reference signal configuration information to the terminal based on instruction information of the terminal;

[0229] Specifically, in the embodiments of the present disclosure, the network side device may send the reference signal configuration information to the terminal in various ways. For example, the network side device may directly send the reference signal configuration information to the terminal; the network side device may also send the reference signal configuration information to the terminal based on indication information sent by the terminal.

[0230] 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 and obtain a measurement result of the reference signal.

[0231] 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 results for model training, updating and monitoring.

[0232] In the reference signal sending method of the disclosed embodiment, the network-side device can directly send reference signal configuration information to the terminal, or send reference signal configuration information to the terminal based on the terminal's indication information, effectively balancing 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 reference signal measurement results for model training, updating, and monitoring. This enables the collection of model training data without the network-side device having to send reference signals on all transmit beams and the terminal having to measure reference signals on all beams, thereby saving the reference signal resource overhead of the network-side device, the measurement overhead of the terminal, and the terminal measurement delay.

[0233] Optionally, the reference signal configuration information includes at least one of the following:

[0234] Configuration information of reference signals in the first reference signal set; measurement results of the reference signals in the first reference signal set are used as input data for model training, model updating, or model monitoring;

[0235] 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;

[0236] a relationship between the first reference signal set and the second reference signal set;

[0237] Pattern information of the first reference signal set.

[0238] Specifically, when training an AI / ML model, it is necessary to obtain input data and label information. In the disclosed embodiment, the measurement results of the reference signals in the first reference signal set are used as 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.

[0239] 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 parameters corresponding to any reference signal in the first reference signal set are different from the spatial reception parameters corresponding to any reference signal in the second reference signal set; and 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, the reference signal configuration information may only configure the first reference signal set or the second reference signal set; 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. The terminal can independently determine the reference signals to be measured in the first reference signal set based on the measurement results of the reference signals in the second reference signal set, thereby allowing the terminal to flexibly obtain the configuration information of the reference signals to be measured in a variety of ways.

[0240] In the data collection method of the embodiment of the present disclosure, 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 thus can collect the input data and label information required for model training to complete the training, monitoring and updating of the terminal-side model.

[0241] Optionally, time domain information, frequency domain information, sequence information and power information of the reference signal.

[0242] Specifically, in the embodiment of the present disclosure, 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.

[0243] Optionally, sending reference signal configuration information to the terminal includes:

[0244] Send a system message to the terminal; the system message carries reference signal configuration information.

[0245] Specifically, in an embodiment of the present disclosure, 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.

[0246] Optionally, sending reference signal configuration information to the terminal based on indication information of the terminal includes:

[0247] Sending multiple reference signal configuration information to the terminal;

[0248] receiving indication information sent by a terminal; the indication information is used to instruct the terminal to select at least one reference signal configuration information from a plurality of reference signal configuration information;

[0249] Reference signal configuration information is sent to the terminal based on the indication information of the terminal.

[0250] Specifically, in an embodiment of the present disclosure, after a network device sends configuration information of multiple reference signals supported by the terminal, the terminal can, based on its own measurement capabilities and model training / update requirements, select at least one reference signal configuration information from the multiple reference signal configuration information sent by the network device and feed it back to the network device. After receiving the feedback information sent by the terminal, the network device can send the corresponding reference signal configuration information to the terminal based on the terminal's selection.

[0251] In the reference signal transmission method of the disclosed embodiments, a network device provides a terminal with multiple optional reference signal configuration information. The terminal can select the appropriate reference signal configuration information based on its own situation and feedback it to the network device. The network device can then transmit the corresponding reference signal to the terminal based on the terminal's selection. In other words, different terminals can select the reference signal configuration information that suits their capabilities and model training / model update requirements from the multiple reference signal configuration information provided by the network device. The reference signal configuration result is jointly determined by the network device and the terminal, effectively balancing the reference signal transmission overhead and the terminal's needs.

[0252] Optionally, sending reference signal configuration information to the terminal based on indication information of the terminal includes:

[0253] receiving indication information sent by a terminal; the indication information is used to indicate reference signal configuration information requested by the terminal;

[0254] Reference signal configuration information is sent to the terminal based on the indication information of the terminal.

[0255] Specifically, in the disclosed embodiments, after receiving indication information sent by a terminal and learning the reference signal configuration information requested by the terminal, the network device can send the reference signal configuration information to the terminal based on the terminal's request. Optionally, because the network device needs to balance the requests of multiple terminals and the reference signal transmission overhead, the reference signal configuration information provided by the network 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 (e.g., reference signal period, transmission window length), thereby effectively balancing the reference signal transmission overhead of the network device and the requirements of the terminal.

[0256] Optionally, the instruction information includes at least one of the following:

[0257] the number of reference signals in the first reference signal set;

[0258] the number of reference signals in the second reference signal set;

[0260] The identification of the model;

[0261] Identification of the model's functionality;

[0262] Dataset identifier;

[0263] Requested data volume or reference signal sending window duration;

[0264] The reason or purpose of the request.

[0265] Specifically, in an embodiment of the present disclosure, the network device may obtain the reference signal configuration requirements of the terminal through the reference signal configuration information explicitly sent by the terminal. For example, the request information for reference signal configuration information received by the network 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 signals corresponding to the first reference signal set and / or the second reference signal set (the terminal may determine the transmission period based on its own moving speed), the data volume of the first reference signal set and / or the reference signals corresponding to the first reference signal set, or the reference signal transmission window duration. Optionally, the network device may also obtain the reference signal configuration requirements of the terminal through the reference signal configuration information implicitly sent by the terminal. For example, the request information for reference signal configuration information received by the network device includes at least one of the following: a model identifier, a model function identifier, a dataset identifier, a requested data volume or a reference signal transmission window duration, and a request reason or request purpose, indicating that the terminal is requesting the reference signal corresponding to the model ID, the model function identifier, or the dataset ID.

[0266] In the reference signal sending method of the embodiment of the present disclosure, the network side device can obtain the reference signal configuration requirement of the terminal through the reference signal configuration information displayed or implicitly sent by the terminal, and the implementation method is flexible and diverse.

[0267] Optionally, sending reference signal configuration information to the terminal based on indication information of the terminal includes:

[0268] A radio resource control (RRC) message is sent to the terminal; the RRC message carries reference signal configuration information.

[0269] Specifically, in an embodiment of the present disclosure, after the network side device receives the indication information sent by the terminal, the network side device can send reference signal configuration information to the terminal 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 the RRC message carries the reference signal configuration information.

[0270] In the reference signal sending method of the disclosed embodiment, 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 signaling resource overhead.

[0271] Optionally, after sending the reference signal to the terminal based on the reference signal configuration information, the method further includes:

[0272] receiving first information sent by a terminal; the first information is used to request to stop reference signal transmission or deactivate reference signal configuration information;

[0273] Sending second information to the terminal; 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.

[0274] Specifically, in an embodiment of the present disclosure, after a network device sends a reference signal to a terminal, if the network device receives the first information sent by the terminal, it can be informed that the terminal has completed the collection of training data, and the network device can then instruct the terminal to deactivate the reference signal configuration information or the terminal to stop receiving the reference signal. Optionally, the network device can also send a timer to the terminal to instruct the terminal to deactivate the reference signal configuration information or the terminal to stop receiving the reference signal after the timer expires.

[0275] According to the reference signal sending method of the embodiment of the present disclosure, the network side device can learn that the terminal has completed the collection of training data by receiving the first information sent by the terminal, so that the network side device can promptly deactivate the reference signal configuration information or stop sending the reference signal, effectively saving the reference signal sending overhead.

[0276] The methods and devices provided in the various embodiments of the present disclosure are based on the same application concept.
