[0090] In another possible implementation, the configuration information for collecting training data is carried in a positioning system information block (posSIB) message, that is, the positioning management function network element can send the configuration information for collecting training data to the terminal device through the posSIB message.

[0091] Optionally, as shown in FIG. 4, the positioning management function network element can send the posSIB message carrying the configuration information for training data collection to the terminal device through the first access network device, that is, step S310 can be replaced by:

[0092] S410, the positioning management function network element sends an assistance information control message to the first access network device through new radio (NR) positioning protocol A (NRPPa) signaling. Correspondingly, the first access network device receives the assistance information control message from the positioning management function network element.

[0093] The assistance information control message is used to configure at least one positioning system information (posSI) message, wherein the at least one posSI message includes the configuration of the first posSIB message, and the first posSIB message carries the configuration information for collecting training data.

[0094] Exemplarily, the positioning management function network element can send the configuration of the first posSIB message to the first access network device through the NRPPa signaling, and the configuration of the first posSIB message is as follows:

[0095] S420, the first access network device sends a first posSIB message carrying configuration information for collecting training data to the terminal device. Correspondingly, the terminal device receives the first posSIB message carrying the configuration information for collecting training data from the first access network device.

[0096] For example, the first access network device can send the first posSIB message to the terminal device through radio resource control (RRC) signaling. The terminal device can receive the first posSIB message carrying the configuration information for collecting training data from the first access network device, decode the first posSIB, and then send training data to the positioning management function network element according to the configuration information for collecting training data in the first posSIB message. The first posSIB message is as follows:

[0097] Alternatively, as shown in FIG. 5, as a possible implementation, step S420 can be replaced by S430, that is, it can be understood that in the communication method provided in the embodiments of the present application, the method 300 does not exist, and step S430 is as follows:

[0098] S430, the first access network device sends an assistance information feedback message to the positioning management function network element through NRPPa signaling. Correspondingly, the positioning management function network element receives the assistance information feedback message from the first access network device.

[0099] In the embodiments of the present application, the assistance information feedback contains an assistance information failure list, and the list contains the type of the posSIB message corresponding to the first posSIB message, indicating that the first access network device fails to send the first posSIB message.

[0100] For example, the assistance information feedback sent by the first access network device to the positioning management function network element through NRPPa signaling is as follows:

[0101] For example, the type of the first posSIB message can be posSIBType6-1, the type of the first posSIB message can be posSIBType8-1, or it can be other types of posSIB messages, which are not limited in the embodiments of the present application. For example, posSIBType6-1 can be used to carry assistance data for collecting training data, and posSIBType8-1 can be used to carry a request for collecting training data, which are not limited in the embodiments of the present application.

[0102] In the embodiments of the present application, the assistance data used for collecting training data includes first PRS configuration related assistance data. Optionally, the assistance data used for collecting training data also includes terminal device position estimation assistance data, which is not described herein.

[0103] The first PRS configuration related assistance data includes one or more of the following: first indication information, or a candidate PRS resource index list. The first indication information is used to indicate one or more second access network devices that send PRS, and / or PRS configuration information corresponding to each of the one or more second access network devices.

[0104] In a possible implementation, the one or more second access network devices send PRS to the terminal device, and the terminal device can measure the PRS to obtain measurement data.

[0105] For example, the second access network device can be a transmission and receiving point (TRP), wherein the one or more second access network devices can or can not include the first access network device, and the embodiments of the present application do not limit this.

[0106] The candidate PRS resource index list indicates PRS resources that need to be measured by the terminal device. For example, the candidate PRS resource index list can include PRS resources corresponding to beams covering the terminal device and adjacent beams. In this scheme, the first PRS configuration related assistance data includes the candidate PRS resource index list, the terminal device measures PRS resources in the candidate PRS resource index list, and sends corresponding measurement data to the positioning management function network element, which can enable the terminal device to measure PRS according to the candidate PRS resource index list to obtain measurement data, thereby increasing the accuracy of the measurement data, avoiding resource waste caused by excessive measurement by the terminal device, and further helping to ensure consistency between model training and model inference and improve positioning accuracy.

[0107] As a possible implementation, the first PRS configuration related assistance data does not include the candidate PRS resource index list, i.e., the candidate PRS resource index list is default, and the terminal device needs to measure and report measurement data and / or label data corresponding to all configured PRS resources. In this way, the terminal device can measure all configured PRS resources, which can improve the generalization of the AI model for beam configuration.

[0108] Exemplarily, in the case that the assistance data for collecting training data is the same as the assistance data for positioning, i.e., the terminal device acquires training data by using the assistance data for positioning, the positioning management function network element sends the assistance data for positioning to the terminal device through LPP signaling, as shown below:

[0109] Exemplarily, in the case that the assistance data for collecting training data is different from the assistance data for positioning, i.e., the terminal device acquires training data by using the assistance data for collecting training data, the positioning management function network element sends the assistance data for collecting training data to the terminal device through LPP signaling, as shown below:

[0110] S320, the terminal device sends training data to the positioning management function network element according to the configuration information for collecting training data. Correspondingly, the positioning management function network element receives the training data from the terminal device.

[0111] Exemplarily, the positioning management function network element can introduce an information element (IE) for the AI positioning method in the LPP signaling when the terminal device needs to report measurement data and label data at the same time, so as to distinguish the non-AI positioning method and the AI positioning method.

[0112] In a possible implementation manner, the positioning management function network element sends a request for collecting measurement data and a request for collecting label data to the terminal device through the IE for the AI positioning method, and the terminal device provides measurement data and label data to the positioning management function network element through the IE for the AI positioning method.

[0113] In another possible implementation manner, the positioning management function network element sends a request for collecting measurement data to the terminal device through the IE for the AI positioning method, and sends a request for collecting label data to the terminal device through a location information request (NR-DL-TDOA-RequestLocationInformation) IE based on a downlink time difference of arrival (DL-TDOA) method and / or a location information request (NR-DL-AoD-RequestLocationInformation) IE based on a downlink angle of departure (DL-AoD) method, and the terminal device sends measurement data to the positioning management function network element through the IE for the AI positioning method, and sends label data to the positioning management function network element through a location information report (NR-DL-TDOA-ProvideLocationInformation) IE based on the DL-TDOA method and / or a location information report (NR-DL-AoD-ProvideLocationInformation) IE based on the DL-AoD method.

[0114] In another possible implementation, when the terminal device needs to report the measurement data and the tag data at the same time, the positioning management function network element sends a request for collecting the measurement data and a request for collecting the tag data to the terminal device through an NR-DL-TDOA-RequestLocationInformation IE and / or an NR-DL-AoD-RequestLocationInformation IE, and the terminal device sends the measurement data and the tag data to the positioning management function network element through an NR-DL-TDOA-ProvideLocationInformation IE and / or an NR-DL-AoD-ProvideLocationInformation IE.

[0115] Optionally, the communication method provided in the embodiments of the present application further includes:

[0116] S330, the positioning management function network element trains the AI model according to the training data.

[0117] In a possible implementation, after receiving the training data, the positioning management function network element can train the AI model, thereby improving the reliability of the AI model.

[0118] Optionally, as shown in FIG. 3, the communication method provided in the embodiments of the present application further includes:

[0119] S340, the positioning management function network element sends the first network additional condition to the terminal device. Correspondingly, the terminal device receives the first network additional condition from the positioning management function network element.

[0131] Alternatively, the first network additional condition can comprise other network status information, which is not limited in the embodiments of the application.

[0132] Optionally, as shown in FIG. 3, the communication method provided by the embodiments of the application further comprises:

[0133] S350, the terminal device sends first feedback information to the location management function network element. Correspondingly, the location management function network element receives the first feedback information from the terminal device.

[0134] In the embodiments of the application, the first feedback information indicates that the first network additional condition is different from the second network additional condition, where the second network additional condition is a network additional condition of the AI model in the training stage, and the second network additional condition indicates part or all network status information of the one or more second access network devices in the model training stage.

[0135] The second network additional condition comprises part or all of network states of the one or more second access network devices in the model training stage, and / or at least one second association ID, the at least one second association ID indicating part or all of network state information of the one or more second access network devices in the model training stage.

[0136] Specific examples of the second network additional condition can refer to specific examples of the first network additional condition, which are not described herein again.

[0137] In the embodiments of the present application, the first feedback information can comprise one or more of the following: an error indication, network state information that is different between part or all of network state information of the one or more second access network devices in the model inference stage included in the first network additional condition and part or all of network state information of the one or more second access network devices in the model training stage included in the second network additional condition, or an association ID that is different between the at least one second association ID and the at least one first association ID. The error indication is used to indicate that the first network additional condition is different from the second network additional condition.

[0138] For example, the first feedback information sent by the terminal device to the location management function network element can be as follows:

[0139] It should be noted that the terminal device can send the first feedback information before AI positioning, or can send the first feedback information in the process of AI positioning, and the embodiments of the present application do not limit this.

[0140] Optionally, as shown in FIG. 3, the communication method provided by the embodiments of the present application further comprises:

[0141] S360, the first access network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the first access network device.

[0142] In the embodiments of the present application, the first indication information is used to instruct the terminal device to send training data to the location management function network element.

[0143] In the stage of collecting training data, in one possible implementation manner, the terminal device can send measurement data and label data to the location management function network element. In another possible implementation manner, the terminal device can send measurement data to the location management function network element.

[0144] It should be noted that the form of reporting the measurement data together with the label data is applicable to the case that the label data is provided by the terminal device providing the measurement data, and the form of only reporting the measurement data is applicable to the case that the label data is provided by the network side device (such as the positioning management function network element), and is also applicable to the case that the label data is inaccurate, such as the terminal device that is not a positioning reference unit (PRU), the terminal device with low signal interference noise ratio (SINR), the terminal device in a non line of sight (NLOS) environment, and the like. Therefore, the first access network device can group the plurality of terminal devices according to different situations, and instruct the terminal devices to send the measurement data to the positioning management function network element, or instruct the terminal devices to send the measurement data and the label data to the positioning management function network element. When there are a plurality of terminal devices reporting the training data, the first indication information can be sent through the group common downlink control information (DCI), so as to save the resource for indication.

[0145] In a possible implementation manner, the first indication information is group common DCI for collecting downlink positioning training data. The first indication information comprises one or more of the following: a first information field or a second information field; wherein the first information field is used to indicate the type of the training data. The second information field is used to indicate whether the terminal device reports the quality information of the label data to the first access network device, and the quality information of the label data is used to represent the accuracy of the label data.

[0146] It should be understood that although not embodied in FIG. 3, S320 can be replaced by: the terminal device sends the training data to the positioning management function network element according to the configuration information for collecting the training data and the first indication information. Correspondingly, the positioning management function network element receives the training data from the terminal device.

[0147] For example, the group common DCI for collecting downlink positioning training data is scrambled by a corresponding RNTI (such as defined as DTDC-RNTI), where the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI is divided into multiple blocks, each block corresponding to the control information of a group of terminal devices, and each block includes a first information field and / or a second information field. For example, the first information field occupies 1 bit, and bit 0 indicates that the measurement data and the label data are reported together, and bit 1 indicates that only the measurement data is reported. For another example, the second information field occupies 1 bit, and bit 0 indicates that the quality information of the label data is not reported, and bit 1 indicates that the quality information of the label data is reported. Bit 0 and bit 1 of the first information field and the second information field can also represent meanings opposite to the above examples, which are not limited.

[0148] It should be noted that the number of information bits transmitted in the group common DCI for collecting downlink positioning training data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI for collecting downlink positioning training data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI for collecting downlink positioning data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group common DCI for collecting downlink positioning data, the terminal device blind decodes the information bits of the group common DCI for collecting downlink positioning data, where the position index of the first bit of the block corresponding to the terminal device in the group common DCI for collecting downlink positioning data is indicated by a high-level parameter.

[0149] In another possible implementation, the first indication information is a group common DCI for collecting training data. The first indication information includes one or more of the following: a first information field, or a second information field. The first information field is used to indicate the type of training data. The second information field is used to indicate whether the terminal device reports quality information of the label data to the first access network device, and the quality information of the label data is used to represent the accuracy of the label data.

[0150] Optionally, although not embodied in FIG. 3, the communication method provided by the embodiments of the present application further includes: the first access network device sends a first high-level parameter to the terminal device. Correspondingly, the terminal device receives the first high-level parameter from the first access network device.

[0151] In the embodiments of the present application, the first high-level parameter indicates that the first indication information is used to collect downlink positioning training data.

[0152] It should be understood that although not embodied in FIG. 3, S320 can be replaced by: the terminal device sends training data to the positioning management function network element according to the configuration information for collecting training data, the first indication information, and the first high-layer parameter.

[0153] For example, the group-common DCI for collecting training data is scrambled by a corresponding RNTI (such as defined as TDC-RNTI), where the value range of the RNTI is 0001-FFF2. The information transmitted by the group-common DCI for collecting training data is divided into multiple blocks, each block corresponds to the control information of a group of terminal devices, and the fields present in the block are explicitly indicated and / or implicitly indicated by the first high-layer parameter. For the terminal device of downlink positioning, the explicitly indicated manner is that the high-layer parameter indicates downlink AI positioning, and the implicitly indicated manner is that the terminal device is pre-configured with PRS-related configuration, at this time, the first information field and / or the second information field are present in the block. For example, the first information field occupies 1 bit, and bit 0 indicates that the measurement data and the label data are reported together, and bit 1 indicates that only the measurement data is reported. For another example, the second information field occupies 1 bit, and bit 0 indicates that the quality information of the label data is not reported, and bit 1 indicates that the quality information of the label data is reported. Bit 0 and 1 of the first information field and the second information field can also represent the opposite meaning of the above examples, which is not limited.

[0154] It should be noted that the number of information bits transmitted in the group-common DCI for collecting training data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group-common DCI for collecting training data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group-common DCI for collecting training data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and the common search space corresponding to the group-common DCI for collecting training data, the terminal device decodes the information bits of the group-common DCI for collecting training data by blind detection, where the position index of the first bit of the block corresponding to the terminal device in the group-common DCI for collecting training data is indicated by the high-layer parameter, and at the same time, the terminal device receives the high-layer parameter indicating downlink AI positioning and / or pre-configured PRS-related configuration to determine whether the first information field and / or the second information field is present in the block.

[0155] Optionally, as shown in FIG. 3, the communication method provided by the embodiments of the present application further comprises:

[0156] S370, the first access network device sends second indication information to the terminal device. Correspondingly, the terminal device receives the second indication information from the first access network device.

[0157] In the embodiments of the present application, the second indication information is used to instruct the terminal device to send monitoring data to the positioning management function network element, and the monitoring data is used to monitor the AI model performance.

[0158] In the stage of collecting monitoring data, in one possible implementation, the terminal device can send measurement data and label data to the positioning management function network element. In another possible implementation, the terminal device can send measurement data to the positioning management function network element. In yet another possible implementation, the terminal device can send label data to the positioning management function network element.

[0159] It should be noted that the form of reporting measurement data and label data together is applicable to the case where the label data is provided by the terminal device providing the measurement data, the form of reporting only measurement data is applicable to the case where the label data is provided by the network side device (such as the positioning management function network element), the form of reporting only label data is applicable to the case where the data provided by the surrounding terminal device is used as label data and / or auxiliary information, and is also applicable to the case where the positioning management function network element monitors the terminal device side model and the label data is provided by the terminal device providing the inference result. Therefore, the first access network device can group a plurality of terminal devices according to the above different cases, instruct the terminal device to report measurement data and label data, or instruct the terminal device to report measurement data, or instruct the terminal device to report label data. When there are a plurality of terminal devices reporting training data, the second indication information can be sent through group common DCI to save the resource of indication.

[0160] In one possible implementation, the second indication information is group common DCI used to collect downlink positioning monitoring data. The second indication information includes one or more of the following: a third information field, or a fourth information field. The third information field is used to indicate the type of monitoring data, and the type of monitoring data includes one or more of the following: measurement data, or label data; and the fourth information field is used to indicate whether the terminal device sends quality information of label data to the first access network device, and the quality information of label data is used to represent the accuracy of the label data.

[0161] It should be understood that although not embodied in FIG. 3, S320 can be replaced by: the terminal device sends training data to the positioning management function network element according to the configuration information used to collect training data and the second indication information. Correspondingly, the positioning management function network element receives the training data from the terminal device.

[0162] For example, the group common DCI for collecting downlink positioning monitoring data is scrambled by a corresponding RNTI (such as DMDC-RNTI) with a value range of 0001-FFF2. The information transmitted by the group common DCI for collecting downlink positioning monitoring data is divided into multiple blocks, each block corresponding to the control information of a group of terminal devices, and there is a third information field and / or a fourth information field in the block. The third information field occupies 2 bits, and bits 00 represent simultaneous reporting of measurement data and label data, bits 01 represent reporting only measurement data, and bits 10 represent reporting only label data. The fourth information field indicates 1 bit, and bit 0 represents not reporting quality information of label data, and bit 1 represents reporting quality information of label data. The 4 bits of the third information field can also represent different meanings from the above example, and the 2 bits of the fourth information field can also represent meanings opposite to the above example, which are not limited.

[0163] It should be noted that the number of information bits transmitted in the group common DCI for collecting downlink positioning monitoring data is not greater than the number of information bits of DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted by the group common DCI for collecting downlink positioning monitoring data is less than the number of information bits of DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI for collecting downlink positioning monitoring data until the number of bits is consistent with DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group common DCI for collecting downlink positioning monitoring data, the terminal device decodes the information bits of the group common DCI for collecting downlink positioning monitoring data by blind decoding, wherein the first bit of the block corresponding to the terminal device is indicated by a high-level parameter.

[0164] In another possible implementation, the second indication information is a group common DCI for collecting monitoring data. The second indication information includes one or more of the following: a third information field or a fourth information field; wherein the third information field is used to indicate the type of monitoring data; and the fourth information field is used to indicate whether the terminal device reports quality information of label data to the first access network device, and the quality information of label data is used to represent the accuracy of the label data.

[0165] Optionally, although not embodied in FIG. 3, the communication method provided by the embodiments of the present application further includes: the first access network device sends a second high-level parameter to the terminal device. Correspondingly, the terminal device receives the second high-level parameter from the first access network device.

[0166] In the embodiments of the present application, the second high-layer parameter indicates that the second indication information is used for collecting downlink positioning monitoring data.

[0167] It should be understood that although not embodied in FIG. 3, S320 can be replaced by: the terminal device sends training data to the positioning management function network element according to the configuration information used for collecting training data, the second indication information, and the second high-layer parameter.

[0168] For example, the group common DCI used for collecting monitoring data is scrambled by a corresponding RNTI (such as defined as MDC-RNTI), wherein the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI used for collecting monitoring data is divided into multiple blocks, each block corresponds to the control information of a group of terminal devices, and the fields present in each block are explicitly indicated and / or implicitly indicated by the second high-layer parameter. For the UE of downlink positioning, the explicit indication is that the second high-layer parameter indicates downlink positioning, and the implicit indication is that the terminal device is pre-configured with PRS related configuration, and at this time, the third information field and / or the fourth information field are present in the block. For example, the third information field occupies 2 bits, and bits 00 represent that the measurement data and the label data are reported at the same time, bits 01 represent that only the measurement data is reported, and bits 10 represent that only the label data is reported. The fourth information field occupies 1 bit, and bit 0 represents that the quality information of the label data is not reported, and bit 1 represents that the quality information of the label data is reported.

[0169] It should be noted that the number of information bits transmitted in the group common DCI used for collecting monitoring data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI used for collecting monitoring data is less than the number of bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI used for collecting monitoring data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group common DCI used for collecting monitoring data, the terminal device decodes the information bits of the group common DCI used for collecting monitoring data through blind decoding, wherein the first bit of the block corresponding to the terminal device is indicated by the position index of the group common DCI used for collecting monitoring data by the second high-layer parameter, and at the same time, the terminal device receives the second high-layer parameter indicating downlink positioning and / or pre-configured PRS related configuration to determine that the third information field and / or the fourth information field are present in the block.

[0170] Optionally, as shown in FIG. 6, step S360 or step S370 can be replaced by:

[0171] S680, the first access network device sends third indication information to the terminal device. Correspondingly, the terminal device receives the third indication information from the first access network device.

[0172] In the embodiments of the present application, the third indication information is used to instruct the terminal device to send the first data of the AI model to the positioning management function network element, and the first data includes one or more of the following: training data, or monitoring data used to monitor the AI model, and the type of the first data includes one or more of the following: measurement data, or label data.

[0173] In a possible implementation, the third indication information is a group common DCI used to collect downlink positioning first data. The third indication information includes one or more of the following: a fifth information field, or a sixth information field; wherein the fifth information field is used to indicate the type of the first data; and the sixth information field is used to indicate whether the terminal device reports quality information of label data to the positioning management function network element, and the quality information of the label data is used to represent the accuracy of the label data.

[0174] It should be understood that although it is not embodied in FIG. 6, S320 can be replaced by: the terminal device sends the training data to the positioning management function network element according to the configuration information used to collect the training data and the third indication information.

[0175] For example, the fifth information field occupies 2 bits, and the bit 00 indicates that the measurement data and the label data are reported at the same time, the bit 01 indicates that only the measurement data is reported, and the bit 10 indicates that only the label data is reported. For another example, the sixth information field occupies 1 bit, and the bit 0 indicates that the quality information of the label data is not reported, and the bit 1 indicates that the quality information of the label data is reported.

[0176] It should be noted that the number of information bits transmitted in the group common DCI used to collect the downlink positioning first data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI used to collect the downlink positioning first data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI used to collect the downlink positioning first data until the number of bits is consistent with the DCI format 1_0. After receiving the RNTI and the common search space corresponding to the group common DCI used to collect the downlink positioning first data configured by the RRC signaling, the terminal device decodes the information bits of the group common DCI used to collect the downlink positioning first data through blind decoding, wherein the position index of the first bit of the block corresponding to the terminal device in the group common DCI used to collect the downlink positioning first data is indicated by the higher layer parameter.

[0177] In another possible implementation, the third indication information is a group common DCI used to collect the first data. The third indication information includes one or more of the following: a fifth information field, or a sixth information field; wherein the fifth information field is used to indicate the type of the first data; and the sixth information field is used to indicate whether the terminal device reports the quality information of the label data to the first access network device, the quality information of the label data being used to represent the accuracy of the label data.

[0178] Optionally, although not embodied in FIG. 6, the communication method provided in the embodiments of the present application further includes: the first access network device sends a third higher layer parameter to the terminal device. Correspondingly, the terminal device receives the third higher layer parameter from the first access network device.

[0179] In the embodiments of the present application, the third higher layer parameter indicates that the third indication information is used to collect the downlink positioning first data.

[0180] It should be understood that although not embodied in FIG. 6, S320 can be replaced by: the terminal device sends the training data to the positioning management function network element according to the configuration information used to collect the training data, the third indication information, and the third higher layer parameter.

[0181] Exemplarily, the group common DCI for collecting the first data is scrambled by a corresponding RNTI (such as defined as DC-RNTI), wherein the RNTI has a value range of 0001-FFF2. The information transmitted by the group common DCI for collecting the first data is divided into multiple blocks, each block corresponds to control information of a group of terminal devices, and the fields present in the block are explicitly indicated and / or implicitly indicated by a third high-layer parameter. For the terminal device in downlink positioning, the explicit indication is that the third high-layer parameter indicates downlink positioning, and the implicit indication is that the terminal device is pre-configured with PRS related configuration, and at this time, the fifth information field and / or the sixth information field are present in the block. For example, the fifth information field can occupy 2 bits, and bits 00 represent that the measurement data and the label data are reported at the same time, bits 01 represent that only the measurement data is reported, and bits 10 represent that only the label data is reported. For another example, the sixth information field occupies 1 bit, and bit 0 represents that the quality information of the label data is not reported, and bit 1 represents that the quality information of the label data is reported.

[0182] It should be noted that the number of information bits transmitted in the group common DCI for collecting the first data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI for collecting the first data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI for collecting the first data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI corresponding to the group common DCI for collecting the first data and the common search space, the terminal device decodes the information bits of the group common DCI for collecting the first data by blind detection, wherein the position index of the first bit of the block corresponding to the terminal device in the group common DCI for collecting the first data is indicated by the high-layer parameter, and at the same time, the terminal device receives the third high-layer parameter indicating downlink positioning and / or is pre-configured with PRS related configuration, to determine that the fifth information field and / or the sixth information field are present in the block.

[0183] The communication method provided by the embodiment of the present application provides a way of collecting training data.

[0184] Exemplarily, as shown in FIG. 7, it is a schematic diagram of an example of the communication method provided by the embodiment of the present application. In this method, the first access network device initiates the collection of training data. The method 700 includes the following steps:

[0185] S710, the first access network device sends configuration information for collecting training data to the terminal device. Correspondingly, the terminal device receives the configuration information for collecting training data from the first access network device.

[0186] In the embodiments of the present application, the training data is training data of an AI model, and the AI model is used for positioning. Optionally, the training data can be used to train the AI model.

[0187] In the embodiments of the present application, the type of the training data includes one or more of the following: measurement data, or label data. The measurement data is obtained by the terminal device measuring PRS.

[0188] In the embodiments of the present application, the configuration information for collecting training data includes one or more of the following: assistance data for collecting training data, or a request for collecting training data.

[0189] In a possible implementation, the configuration information for collecting training data includes the assistance data for collecting training data, and the terminal device can collect the training data according to the assistance data for collecting training data.

[0191] In yet another possible implementation, the configuration information for collecting training data includes the assistance data for collecting training data and the request for collecting training data, and the terminal device can collect the training data according to the assistance data for collecting training data and the request for collecting training data.

[0192] Alternatively, as a possible implementation, the first access network device can not send the configuration information for collecting training data to the terminal device, and the terminal device can obtain the training data according to the assistance data in the configuration information for positioning, and then send the training data to the first access network device. Alternatively, the first access network device and the terminal device can obtain the training data through other manners, which are not limited in the embodiments of the present application.

[0193] Optionally, the request for collecting training data can include one or more of the following: a request for collecting measurement data, or a request for collecting label data.

[0194] In the embodiments of the present application, the assistance data for collecting training data and the assistance data in the configuration information for positioning can be the same or different, which are not limited in the embodiments of the present application.

[0195] In a possible implementation, the configuration information for collecting the training data is carried in a system information block (SIB) message. Alternatively, the first access network device can send the configuration information for collecting the training data to the terminal device through the SIB message.

[0196] For example, the first access network device configures, through the SIB1, scheduling information of an SI message containing a first SIB message (for example, the first SIB message can be SIB27, and the present application does not limit the first SIB message) that contains the configuration information for collecting the training data. For example, the period of the SI message can be configured as at least one of 8, 16, 32, 64, 128, 256, or 512, and the unit is frame, and the present application does not limit the period. The terminal device receives and decodes the first SIB message according to the physical downlink shared channel (PDSCH) time-frequency resource obtained by decoding the DCI format 1_0 scrambled by the SI-RNTI in the SI window corresponding to the SI message containing the first SIB message configured by the SIB1 message, and performs PRS measurement according to the configuration information for collecting the training data carried in the first SIB message, and reports the training data to the first access network device. The first SIB message (SIB27) is shown in the following example:

[0197] In another possible implementation, the configuration information for collecting the training data is carried in RRC signaling. Alternatively, the first access network device sends the configuration information for collecting the training data to the terminal device through the RRC signaling.

[0198] Alternatively, as a possible implementation, the measurement data measured by the terminal device can be used for minimization drive test (MDT), and the measurement data includes at least one of the following: DP, PDP, CIR, PS, CFR, or multipath parameters.

[0199] The MDT measurement of the measurement data adopts at least one of the following modes:

[0202] 2. Measurement reporting based on MDT measurement configuration, including at least one of the following reporting modes: periodic reporting, A2 event triggered reporting or A2 event triggered periodic reporting.

[0203] For example, in the instant MDT mode, the RRC measurement configuration configured for the terminal device is as follows:

[0204] II. Logged MDT. As shown in FIG. 8, the logged MDT includes at least one of the following steps:

[0205] Step 1: The first access network device sends a LoggedMeasurementConfiguration message (logged MDT configuration message) to the terminal device through RRC signaling to start the logged MDT process, and requests the terminal device to perform channel measurement and measurement data storage through PRS in the idle state and / or inactive state, and report the channel measurement data when reporting MDT.

[0206] For example, the LoggedMeasurementConfiguration message is as follows:

[0207] Step 2: The terminal device sends a UEInformationResponse message to the first access network device through RRC signaling, which includes the logged MDT results reported, including measurement data and / or UE location information.

[0208] For example, the UEInformationResponse message is as follows:

[0209] In another possible implementation, in the AI-based beam management use case, the beam RSRP and / or beam index measured by the terminal device can also be supported for MDT measurement, and in the AI-based CSI prediction use case, the channel matrix and / or the feature vector corresponding to the channel matrix measured by the terminal device can also be supported for MDT measurement. The MDT measurement of these measurement quantities can also use the instant MDT mode and / or the logged MDT mode.

[0210] The configuration mode of measurement collection and reporting triggering in the instant MDT mode is as described in mode 1, and the RRC measurement configuration configured for the terminal device is as follows:

[0211] In the logged MDT mode, there are at least the following at least one step:

[0212] Step one: the first access network device sends a LoggedMeasurementConfiguration message to the terminal device through RRC signaling to start the logged MDT process, and requests the UE to measure at least one of the following measurement quantities through SSB and / or CSI-RS in the idle state and / or inactive state: beam RSRP, beam index, channel matrix, or eigenvector corresponding to the channel matrix, store the measurement data, and report the stored measurement data when reporting MDT.

[0213] For example, the LoggedMeasurementConfiguration message is as follows:

[0214] Step two: the terminal device sends a UEInformationResponse message to the network side through RRC signaling, and the message includes the reported logged MDT result, which includes at least one of the following data: beam RSRP, beam index, channel matrix, or eigenvector corresponding to the channel matrix.

[0215] For example, the UEInformationResponse message is as follows:

[0225] The related description of the first indication information can refer to the related description in step S370, and only the first indication information used for instructing the terminal device to send the monitoring data to the positioning management function network element is replaced by the second indication information used for instructing the terminal device to send the monitoring data to the first access network device. Correspondingly, the corresponding description that the terminal device sends the training data to the positioning management function network element according to the second indication information is modified to the corresponding description that the terminal device sends the monitoring data to the first access network device according to the second indication information, and details are not described herein again.

[0226] Optionally, as shown in FIG. 9, step S730 or step S740 can be replaced by:

[0227] S950, the first access network device sends third indication information to the terminal device. Correspondingly, the terminal device receives the third indication information from the first access network device.

[0228] In the embodiment of the present application, the third indication information is used for instructing the terminal device to send the first data to the first access network device.

[0229] The related description of the third indication information can refer to the related description in step S680, and only the third indication information used for instructing the terminal device to send the first data to the positioning management function network element is replaced by the third indication information used for instructing the terminal device to send the first data to the first access network device. Correspondingly, the corresponding description that the terminal device sends the first data to the positioning management function network element according to the third indication information is modified to the corresponding description that the terminal device sends the first data to the first access network device according to the third indication information, and details are not described herein again.

[0230] The communication method provided in the embodiment of the application includes that a first access network device sends configuration information for collecting training data to a terminal device, the terminal device receives the configuration information for collecting training data from the first access network device, collects training data according to the configuration information for collecting data, and sends the training data to the first access network device, thereby providing a way for collecting training data.

[0231] Exemplarily, as shown in FIG. 10, it is a schematic diagram of an example of the communication method provided in the embodiment of the application. In the method, a positioning management function network element initiates collection of training data, and the method 1000 includes the following steps.

[0232] S1010, the positioning management function network element sends configuration information for collecting training data to a first access network device. Correspondingly, the first access network device receives the configuration information for collecting training data from the positioning management function network element.

[0233] In the embodiment of the application, the training data is training data of an AI model, and the AI model is used for positioning.

[0234] In the embodiment of the application, the training data includes one or more of the following: first measurement data, or positioning intermediate quantities, wherein the first measurement data is obtained by one or more second access network devices performing measurement on sounding reference signals (SRS).

[0235] The one or more second access network devices include the first access network device, or the one or more second access network devices do not include the first access network device, which is not limited in the embodiment of the application.

[0236] In a possible implementation, the configuration information for collecting training data is carried in NRPPa signaling.

[0237] In the embodiment of the application, the configuration information for collecting training data includes one or more of the following: first indication information, or a request for collecting training data. The first indication information is used to indicate first SRS configuration information.

[0238] Optionally, the request for collecting training data can include a request for collecting first measurement data, and / or a request for collecting positioning intermediate quantities.

[0239] The positioning intermediate quantities can include one or more of the following: RTOA, AoA, multiple AoAs, LOS / NLOS indication, RSRP, RSRPP, gNB side Rx-Tx time difference.

[0240] Exemplarily, the configuration information for collecting training data sent by the positioning management function network element to the first access network device through NRPPa signaling is as follows:

[0241] S1020, the first access network device sends training data to the positioning management function network element. Correspondingly, the positioning management function network element receives the training data from the first access network device.

[0242] Optionally, as shown in FIG. 10, the communication method provided by the embodiment of the application further includes:

[0243] S1030, the positioning management function network element trains the AI model according to the training data.

[0244] In a possible implementation, after receiving the training data, the positioning management function network element can train the AI model, thereby improving the reliability of the AI model.

[0245] Optionally, as shown in FIG. 10, the communication method provided by the embodiment of the application further includes:

[0246] S1040, the positioning management function network element sends a transmission requirement of SRS for collecting training data to the first access network device. Correspondingly, the first access network device receives the transmission requirement of SRS for collecting training data from the positioning management function network element.

[0247] The transmission requirement of SRS for collecting training data can be the same as or different from the transmission requirement of SRS for positioning, and the embodiment of the application does not limit this. For example, since the model training is non-real-time, the SRS resource for collecting training data can be configured with a longer transmission period. In addition, the measurement corresponding to the SRS for collecting training data can be different from the SRS for positioning in terms of channel estimation, beam management, positioning, and the like. The corresponding measurement is at least one of the following measurement data: DP, PDP, CIR, PS, CFR or multipath parameter.

[0248] For example, the transmission requirement of SRS for collecting training data sent by the positioning management function network element to the first access network device can be as follows:

[0249] S1050, the first access network device sends first SRS configuration information to the positioning management function network element. Correspondingly, the positioning management function network element receives the first SRS configuration information from the first access network device.

[0250] The first SRS configuration information includes configuration information of the SRS for collecting training data configured by the first access network device to the terminal device.

[0251] The first SRS configuration information can be the same as or different from the SRS configuration information for positioning, and the embodiment of the application does not limit this.

[0252] For example, when the first SRS configuration information is different from the SRS configuration information for positioning, the first SRS configuration information sent by the first access network device to the positioning management function network element through the NRPPa signaling is as follows:

[0253] Optionally, as shown in FIG. 10, the communication method provided by the embodiment of the application further includes:

[0254] S1060, the positioning management function network element sends a first request to the terminal device. Correspondingly, the terminal device receives the first request from the positioning management function network element.

[0255] In the embodiment of the application, the first request is used to request the label data of the first measurement data. Optionally, the first request can include a reporting mode of the label data of the first measurement data obtained by measuring the PRS.

[0256] For example, the first request can be as follows:

[0257] S1070, the terminal device sends a first response to the positioning management function network element. Correspondingly, the positioning management function network element receives the first response from the terminal device.

[0258] In a possible implementation manner, the first response includes one or more of the following: the label data of the first measurement data, the timestamp corresponding to the label data of the first measurement data, or the second indication information; wherein the label data of the first measurement data is determined by the terminal device based on the second measurement data, the second measurement data is obtained by the terminal device measuring the PRS, and the second indication information is used to indicate that the second measurement data is the label data of the first measurement data. That is, in this implementation manner, the terminal device determines that the second measurement data is the label data of the first measurement data.

[0259] For example, the terminal device determines whether the second measurement data can be used as the label data corresponding to the first measurement data based on its own implementation. For example, it is determined whether the position of the terminal device when receiving the PRS and the position of the terminal device when sending the SRS are consistent, and if the terminal device determines that the second measurement data obtained by the PRS is used as the label data corresponding to the first measurement data, the label data of the first measurement data, the timestamp corresponding to the label data of the first measurement data, or the second indication information is sent to the positioning management function network element.

[0260] Or, the terminal device determines that the second measurement data cannot be the label data corresponding to the first measurement data, and provides the following at least one data to the location management function network element: the second measurement data, and a reason why the second measurement data cannot be the label data corresponding to the first measurement data. The reason can be, for example, that the terminal device position when the PRS is received and the terminal device position when the SRS is sent are inconsistent.

[0261] For example, the terminal device sends the first response to the location management function network element as follows:

[0262] In another possible implementation, the first response includes one or more of the following: the second measurement data, a timestamp corresponding to the second measurement data, or a stationary duration; and the method further includes: determining, by the location management function network element, that the second measurement data is the label data of the first measurement data according to the first response; and wherein the second measurement data is obtained by the terminal device measuring the PRS. That is, in this implementation, the location management function network element determines that the second measurement data is the label data of the first measurement data.

[0263] For the stationary duration, if the PRS used to obtain the second measurement data is received before the SRS is sent, the stationary duration is the difference between the SRS sending time and the time of the last position change before the SRS is sent, and if the PRS used to obtain the second measurement data is received after the SRS is sent, the stationary duration is the difference between the PRS receiving time and the time of the last position change before the PRS is received. The stationary duration is used to assist the location management function network element in determining whether to use the second measurement data as the label data corresponding to the first measurement data for model training or model monitoring.

[0264] For example, the terminal device reports the data matching information to the location management function network element as follows. In this example, the stationary duration is in units of symbols, and if the stationary duration exceeds the value range, the maximum value 8960 is taken.

[0265] The communication method provided by the embodiments of the present application includes: the location management function network element sends configuration information for collecting training data to the first access network device; the first access network device receives the configuration information for collecting training data from the location management function network element, collects training data according to the configuration information for collecting training data, and sends the training data to the location management function network element, thereby providing a way to collect training data.

[0266] For example, as shown in FIG. 11, the method is an example of the communication method provided by the embodiments of the present application, and in this method, the first access network device sends the collection of training data. The method 1100 includes:

[0267] S1110, the first access network device sends configuration information for collecting training data to the terminal device. Correspondingly, the terminal device receives the configuration information for collecting training data from the first access network device.

[0268] In the embodiments of the present application, the training data is training data of an AI model, and the AI model is used for positioning.

[0269] In the embodiments of the present application, the configuration information for collecting training data includes one or more of the following: first SRS configuration information, or location reporting configuration information.

[0270] The first SRS configuration information includes configuration of an SRS resource set for data collection, and the configuration of the SRS resource set is used for the terminal device to send SRS to one or more second access network devices.

[0271] The location reporting configuration information is used for the terminal device to send location information to the first access network device.

[0272] The first SRS configuration information is used for scheduling the sending of SRS, and the location reporting configuration information is used for scheduling the location reporting of the terminal device to assist the first access network device to complete the collection of measurement data and / or label data.

[0273] In the embodiments of the present application, the training data can include one or more of the following: measurement data, or label data. The measurement data is obtained by one or more second access network devices measuring SRS. The label data includes location information.

[0274] In a possible implementation, the configuration information for collecting training data is carried in RRC signaling. Or in other words, the first access network device sends the configuration information for collecting training data to the terminal device through RRC signaling.

[0275] For example, since model training is non-real-time, the SRS resource for collecting training data can be configured with a longer transmission period.

[0276] In addition, the measurement corresponding to the SRS for collecting training data is also different from the SRS for traditional channel estimation, beam management, positioning, etc. The corresponding measurement is at least one of the following channel measurement data: DP, PDP, CIR, PS, CFR or multipath parameter.

[0277] Exemplarily, when the resource type of the SRS resource used for collecting the training data is configured as non-periodic scheduling, the terminal device decodes at least one of the following DCI: DCI format 0_1, DCI format 0_2, DCI format 1_1, DCI format 1_2 or DCI format 2_3, and transmits one or more SRS resource sets indicated by the SRS request field in the DCI to be activated. For a terminal device without a configured service cell supplementary uplink, the SRS request field occupies (is expanded to) 3 bits, and different bit strings correspond to required activated SRS resource sets as shown in Table 1; for a terminal device with a configured service cell supplementary uplink, the first bit indicates whether to transmit SRS on the supplementary uplink, and the remaining bits indicate the required activated SRS resource set, such as the remaining bits occupying (being expanded to) 3 bits, and different bit strings correspond to required activated SRS resource sets as shown in Table 1.

[0278] Table 1

[0279] In the embodiments of the present application, the location reporting configuration information includes one or more of the following: a location reporting configuration identifier ID, a location reporting configuration associated SRS resource set, or a location reporting type.

[0280] In the embodiments of the present application, the location reporting type includes one or more of the following: location periodic reporting, location semi-persistent reporting, or location aperiodic reporting. Among them, the location semi-persistent reporting includes one or more of the following: physical uplink control channel (PUCCH) based location semi-persistent reporting, or physical uplink shared channel (PUSCH) based location semi-persistent reporting.

[0281] Exemplarily, for location periodic reporting, the terminal device is configured with at least one of the following parameters about the location reporting configuration information: reporting period, reporting slot offset, or PUCCH resource.

[0282] The reporting period can be configured with a slot length including at least one of the following: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1280, 2560, 5120, 10240, 20480, 40960 or 81920, consistent with the SRS configurable period.

[0283] The reporting slot offset indicates the time slot difference between the reporting time slot and the first time slot of the first frame. The configurable time slot length is a non-negative integer less than the configured reporting period.

[0284] The PUCCH resource indicates the time-frequency resource and format of the PUCCH used for reporting. Assuming that the reporting period is T loc , the reporting slot offset is T offset , then the time slot in which the terminal device reports the position information is satisfies the following formula:

[0285] For example, for PUCCH-based semi-persistent reporting, the terminal device is configured with at least one of the following parameters related to the reporting configuration: reporting period, reporting slot offset, or PUCCH resource.

[0286] The reporting period configurable time slot length includes at least one of the following: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1280, 2560, 5120, 10240, 20480, 40960, or 81920, consistent with the SRS configurable period.

[0287] The reporting slot offset indicates the time slot difference between the reporting time slot and the first time slot of the first frame. The configurable time slot length is a non-negative integer less than the reporting period configured by RRC signaling.

[0288] The PUCCH resource indicates the time-frequency resource and format of the PUCCH used for reporting. Assuming that the reporting period is T loc , the reporting slot offset is T offset , then the time slot in which the terminal device reports the position information is satisfies the following formula:

[0289] In this position reporting type, the MAC CE indicates whether the position reporting configuration information is activated. If the terminal device receives the MAC CE and the MAC CE indicates to activate the position reporting configuration information, the terminal device reports the position information of the terminal device through the configured PUCCH resource in the time slot that satisfies the above formula. If the terminal device receives the MAC CE and the MAC CE indicates to deactivate the position reporting configuration information, the terminal device no longer reports the position information of the terminal device.

[0290] For example, for PUSCH-based semi-persistent reporting, the terminal device is configured with a reporting period and / or a reporting slot offset list.

[0291] The reporting period configurable slot length includes at least one of 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1280, 2560, 5120, 10240, 20480, 40960, or 81920, consistent with the SRS configurable period.

[0292] The reporting slot offset list represents a list of candidate values of the time slot difference between the time slot of the report and the time slot of the DCI triggering the location reporting configuration information, and the number of candidate values is at most 16, and the range of the candidate values is 0-128.

[0293] In this location reporting type, the DCI indicates that the terminal device activates or deactivates the location reporting configuration information, wherein the DCI is at least one of DCI format 0_0, DCI format 0_1, DCI format 0_2, or DCI format 0_3, and the DCI indicates the reporting slot offset and the time-frequency resource of the PUSCH. If the terminal device receives the uplink scheduling DCI and the DCI indicates to activate the location reporting configuration information, the terminal device reports for the first time in the PUSCH resource configured in the time slot corresponding to the reporting slot offset indicated by the DCI, and then reports in the corresponding time slot according to the configured reporting period. If the terminal device receives the DCI and the DCI indicates to deactivate the reporting configuration, the terminal device does not report the location information of the terminal device.

[0294] For example, for aperiodic reporting, the terminal device is configured with a reporting slot offset list. The reporting slot offset list represents a list of candidate values of the time slot difference between the time slot of the report and the time slot of the DCI triggering the location reporting configuration information, and the number of candidate values is at most 16, and the range of the candidate values is 0-128.

[0295] In this reporting type, the DCI indicates that the terminal device activates the location reporting configuration information, wherein the DCI is at least one of DCI format 0_0, DCI format 0_1, DCI format 0_2, or DCI format 0_3, and the DCI indicates the reporting slot offset and the time-frequency resource of the PUSCH. If the terminal device receives the uplink scheduling DCI and the DCI indicates to activate the location reporting configuration information, the terminal device reports in the PUSCH resource configured in the time slot corresponding to the reporting slot offset indicated by the DCI.

[0296] If the physical channel resources scheduled by the location reporting configuration information of the two terminal devices are transmitted on the same carrier and overlap at least on one symbol, the reporting of the location information of the two terminal devices will collide. In order to avoid the collision of the reporting of the location information of the two terminal devices, the priority of the location reporting can be set.

[0297] Optionally, in the embodiments of the present application, the priority corresponding to the location reporting type can include: the priority of the periodic location reporting is greater than that of the semi-persistent location reporting, the priority of the semi-persistent location reporting is greater than that of the aperiodic location reporting, and the priority of the semi-persistent location reporting based on PUSCH is greater than that of the semi-persistent location reporting based on PUCCH. The priority corresponding to the location reporting type is used for sequentially scheduling the reporting of the location information of the terminal device in the case of limited physical resources.

[0298] For example, the above priority is set because the model training needs a large amount of training data, so the priority of the periodic location reporting is greater than that of the semi-persistent location reporting, and the priority of the semi-persistent location reporting is greater than that of the aperiodic location reporting. Because PUSCH can carry more information than PUCCH, the priority of the semi-persistent location reporting based on PUSCH is greater than that of the semi-persistent location reporting based on PUCCH.

[0299] In the embodiments of the present application, the priority of the terminal device reporting the location information corresponding to the location reporting configuration information is determined by the priority value corresponding to the location reporting configuration ID, and the priority of the terminal device reporting the location information corresponding to the location reporting configuration information is negatively related to the priority value corresponding to the location reporting configuration ID.

[0300] For example, if the reporting type corresponding to the location reporting configuration information of the two terminal devices is configured to be the same, the smaller the location reporting configuration ID of the terminal device is, the higher the priority of the location reporting of the terminal device is. Therefore, the priority value (Priority Value) associated with the location reporting configuration information of the terminal device is as follows, wherein s loc represents the location reporting configuration ID of the terminal device, M s,loc represents the maximum value of the location reporting configuration ID of the terminal device, y loc indicates the location reporting type corresponding to the location reporting configuration information of the terminal device, y loc = 0 represents periodic location reporting, y loc = 1 represents semi-persistent location reporting based on PUSCH, y loc = 2 represents semi-persistent location reporting based on PUCCH, y loc = 3 represents aperiodic location reporting. Pri loc (y loc , s loc ) = M s,loc · y loc + sloc

[0301] According to the above priority rules, if the two terminal device location reporting configuration information corresponds to different location reporting types (except that one location reporting type is location periodic reporting and the other location reporting type is PUCCH-based location semi-persistent reporting), the location reporting of the terminal device with high priority is discarded. If the two terminal device location reporting configuration information corresponds to the same location reporting type (y loc ) or the two location reporting types are location periodic reporting and PUCCH-based location semi-persistent reporting respectively, the physical channel resources corresponding to the two terminal device location reporting configuration information are multiplexed for terminal device location reporting or the location information reporting of the terminal device with high priority is discarded.

[0302] In the embodiments of the present application, if the physical channel resources scheduled by the location reporting configuration information and the physical resources scheduled by the CSI reporting configuration information of the same terminal device are transmitted on the same carrier and overlap at least in one symbol, the reporting of the location information and the CSI will also collide. In order to avoid the collision between the terminal device location information reporting and the CSI reporting, at least one of the following priority rules can be set:

[0303] The first priority rule is as follows: Since the model training does not necessarily use labeled data, the priority of the terminal device location information reporting is lower than that of the CSI reporting. Therefore, the associated priority value formula of the CSI reporting is as follows:

[0304] Wherein, s represents the CSI reporting configuration ID, M s represents the maximum value of the CSI reporting configuration ID, c represents the service cell index, N cells represents the maximum number of service cells, k=0 represents the CSI reporting carrying L1-RSRP or L1-SINR, k=1 represents the CSI reporting not carrying L1-RSRP or L1-SINR, y=0 represents CSI aperiodic reporting, y=1 represents PUCCH-based CSI non-persistent reporting, y=2 represents PUCCH-based CSI non-persistent reporting, and y=3 represents CSI periodic reporting. CSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s ·c+s

[0305] The priority value formula of the terminal device location information reporting is as follows: loc (y loc ,s loc )=8·N cells ·Ms +M s,loc ·y loc +s loc

[0306] wherein s loc denotes the terminal device location reporting configuration ID, M s,loc denotes the maximum value of the terminal device location reporting configuration ID, y loc indicates the reporting type corresponding to the terminal device location reporting configuration information, y loc = 0 indicates terminal device location periodic reporting, y loc = 1 indicates terminal device location non-persistent reporting based on PUSCH, y loc = 2 indicates terminal device location non-persistent reporting based on PUCCH, y loc = 3 indicates terminal device location aperiodic reporting.

[0307] The second priority rule is as follows: in order to avoid excessive resource occupation by CSI reporting, the priority of terminal device location periodic reporting is higher than that of CSI semi-persistent reporting based on PUSCH, CSI semi-persistent reporting, and CSI semi-persistent reporting based on PUCCH. The priority of terminal device location aperiodic reporting is lower than that of CSI periodic reporting.

[0308] Correspondingly, the priority formula of CSI reporting is as follows: Pri CSI (y, k, c, s) = 2 · N cells · M s · y + y · M s,loc + N cells · M s · k + M s · c + s

[0309] wherein s denotes the CSI reporting configuration ID, M s denotes the maximum value of the CSI reporting configuration ID, c denotes the serving cell index, N cells denotes the maximum number of serving cells, k = 0 indicates CSI reporting carrying L1-RSRP or L1-SINR, k = 1 indicates CSI reporting not carrying L1-RSRP or L1-SINR, M s,loc denotes the maximum value of the terminal device location reporting configuration ID, y = 0 indicates CSI aperiodic reporting, y = 1 indicates CSI non-persistent reporting based on PUSCH, y = 2 indicates CSI non-persistent reporting based on PUCCH, and y = 3 indicates CSI periodic reporting.

[0310] Correspondingly, the priority formula of terminal device location reporting is as follows: Pri loc (y loc ,s loc) = (2y loc + 2) · N cells · M s + M s,loc · y loc + s loc

[0311] wherein s loc indicates the terminal device location reporting configuration ID, y loc indicates the reporting type corresponding to the terminal device location reporting configuration, y loc = 0 indicates periodic reporting of the terminal device location, y loc = 1 indicates non-persistent reporting of the terminal device location based on PUSCH, y loc = 2 indicates non-persistent reporting of the terminal device location based on PUCCH, y loc = 3 indicates aperiodic reporting of the terminal device location.

[0312] According to the above priority rules, if the reporting type corresponding to the CSI reporting configuration and the reporting type corresponding to the terminal device location reporting configuration information are different (except that one reporting type is periodic reporting and the other reporting type is semi-persistent reporting based on PUCCH), the reporting content with a higher priority is discarded; if the two reporting types are the same or the two reporting types are periodic reporting and semi-persistent reporting based on PUCCH respectively, the physical channel resources corresponding to the CSI reporting configuration and the terminal device location reporting configuration are multiplexed for reporting or the reporting content with a higher priority is discarded.

[0313] In the embodiments of the present application, the correspondence between the scheduling type of the SRS resource set associated with the location reporting configuration information and the location reporting type includes:

[0314] The location reporting type is periodic reporting of the location, and the scheduling type of the SRS resource set associated with the location reporting configuration information is periodic scheduling.

[0315] For example, when the location reporting type is periodic reporting, the resource type of the SRS resource set associated with the location reporting configuration information is periodic scheduling. At this time, the terminal device reports the location information of the terminal device at at least one SRS resource sending time within a reporting period before the reporting time at each reporting time. In order to avoid wasting air interface resources due to reporting empty content, the configured reporting time slot offset should be no less than the minimum value of the time slot offset of the associated SRS resource set, and the configured reporting period should be no less than the minimum value of the period of the associated SRS resource set. Configuring the reporting period to be the minimum value of the period of the associated SRS resource set can reduce the air interface overhead of each reporting, and configuring a large enough reporting period (such as no less than the maximum value of the period of the associated SRS resource set) can reduce the reporting frequency and leave more time-frequency resources.

[0316] The position reporting type is a PUCCH-based position semi-persistent reporting or a PUSCH-based position semi-persistent reporting, and the scheduling type of the SRS resource set associated with the position reporting configuration information is one or more of the following: periodic scheduling, or semi-persistent scheduling.

[0317] For example, when the position reporting type is a PUCCH-based semi-persistent reporting or a PUSCH-based semi-persistent reporting, the resource type of the SRS resource set associated with the position reporting configuration information is periodic scheduling and / or semi-persistent scheduling. At this time, the terminal device reports the position information of the terminal device at at least one SRS resource sending time within a reporting period before the reporting time. In order to avoid wasting air interface resources by reporting empty content, the configured reporting period should be greater than or equal to the minimum value of the period of the associated SRS resource set. Configuring the reporting period to be the minimum value of the period of the associated SRS resource set can reduce the air interface overhead of each report, and configuring a large enough reporting period (such as greater than or equal to the maximum value of the period of the associated SRS resource set) can reduce the reporting frequency to leave more time-frequency resources.

[0318] The position reporting type is a position aperiodic reporting, and the scheduling type of the SRS resource set associated with the position reporting configuration information is one or more of the following: periodic scheduling, semi-persistent scheduling, or aperiodic scheduling.

[0319] For example, when the position reporting type is configured as an aperiodic reporting, the resource type of the SRS resource set associated with the position reporting configuration information is at least one of the following: periodic scheduling, semi-persistent scheduling, or aperiodic scheduling. When the resource type of the SRS resource set associated with the position reporting configuration information is periodic scheduling or semi-persistent scheduling, the terminal device reports the position information of the terminal device at at least one SRS resource sending time within a period before the reporting time, and if the resource type of the SRS resource set associated with the position reporting configuration information also has aperiodic scheduling, the period is the maximum value between the maximum period of the SRS resource set and the maximum difference between the aperiodic SRS and the reporting time, otherwise the period is the maximum period of the SRS resource set. When the resource type of the SRS resource set associated with the position reporting configuration information is all aperiodic scheduling, the terminal device reports the position information of the terminal device at at least one SRS resource sending time within a period before the reporting time, and the period is the maximum difference between the aperiodic SRS and the reporting time.

[0320] In another possible implementation, the configuration information for collecting training data is carried in a SIB message. Or in other words, the first access network device sends the configuration information for collecting training data to the terminal device through the SIB message.

[0321] Exemplarily, the first access network device configures, through the SIB1, scheduling information of an SI message containing a second SIB message (for example, the second SIB message can be a SIB26 message) comprising configuration information for collecting training data, and a period of the SI message is configurable as at least one of 8, 16, 32, 64, 128, 256 or 512, in units of frames. The terminal device receives and decodes the second SIB message according to PDSCH time-frequency resources obtained by decoding DCI format 1_0 scrambled by SI-RNTI in an SI window corresponding to the SI message containing the second SIB message configured by the SIB1, and the terminal device sends training data to the first access network device based on the configuration information for collecting training data included in the second SIB message.

[0322] Exemplarily, the second SIB message can be as follows:

[0323] Alternatively, as a possible implementation, the first access network device can multiplex configuration information of an existing MDT to obtain training data, wherein the configuration information for collecting training data is carried in a newly added field of the configuration information of the MDT. For details, reference can be made to the related description in the method 900, and only uplink is replaced by downlink, which will not be described herein again.

[0324] S1120, the terminal device sends label data and / or the SRS to the first access network device according to the configuration information for collecting training data. Correspondingly, the first access network device receives the label data and / or the SRS from the terminal device.

[0325] Optionally, as shown in FIG. 11, the communication method provided by the embodiment of the present application further comprises:

[0326] S1130, the first access network device trains the AI model according to the training data.

[0327] Optionally, the first access network device receives the SRS from the terminal device and measures to obtain measurement data (applicable to a case where one or more second access network devices include the first access network device).

[0328] In a possible implementation, after receiving the training data, the first access network device can train the AI model, thereby improving the reliability of the AI model.

[0329] Optionally, as shown in FIG. 11, the communication method provided by the embodiment of the present application further comprises:

[0330] S1140, the first access network device sends a first request to the positioning management function network element. Correspondingly, the positioning management function network element receives the first request from the first access network device.

[0331] In the embodiments of the present application, the first request is used to request the tag data. The first access network device can send the first request to the positioning management function network element through NRPPa signaling.

[0332] In a possible implementation, the first request includes a sending timestamp of the SRS, and the SRS is used by the positioning management function network element to obtain the tag data.

[0333] In S1150, the positioning management function network element sends a first response to the first access network device. Correspondingly, the first access network device receives the first response from the positioning management function network element.

[0334] In the embodiments of the present application, the first response includes one or more of the following: the tag data, or the sending timestamp of the SRS. The sending timestamp of the SRS is the sending time of the SRS used by the positioning management function network element to estimate the measurement data corresponding to the tag data.

[0335] Optionally, as shown in FIG. 11, the communication method provided by the embodiments of the present application further includes:

[0336] In S1160, the first access network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the first access network device.

[0337] In the embodiments of the present application, the first indication information is used to instruct the terminal device to send the SRS to one or more second access network devices, and / or to send the tag data to the first access network device.

[0338] When the terminal device sends the SRS, in a possible implementation, the terminal device can send the tag data to the first access network device. In another possible implementation, the terminal device can not send the tag data to the first access network device.

[0339] It should be noted that the case that the terminal device does not send the tag data to the first access network device is applicable to the case that the tag data is provided by the network side device (for example, the positioning management function network element), and is also applicable to the case that the tag data is inaccurate, for example, the data collection object is a terminal device that is not a PRU, a terminal device with low SINR measurement, and a terminal device in a NLOS environment. Therefore, the first access network device can group a plurality of terminal devices according to the above different cases, and instruct the terminal device to send the tag data to the first access network device, or instruct the terminal device not to send the tag data to the first access network device.

[0340] In a possible implementation, the first indication information is a group common DCI for collecting uplink positioning training data, and the first indication information includes one or more of the following: a first information field, a second information field, or a third information field. The first information field is used to indicate a set of SRS resources activated by the terminal device. The second information field is used to indicate whether the terminal device sends label data to the first access network device. The third information field is used to indicate whether the terminal device reports quality information of the label data to the first access network device, and the quality information of the label data is used to represent the accuracy of the label data.

[0341] It should be understood that although not embodied in FIG. 11, S1120 can be replaced with: the terminal device sends label data and / or SRS to the first access network device according to the configuration information for collecting training data and the first indication information. Correspondingly, the first access network device receives the label data and / or SRS from the terminal device.

[0342] For example, the group common DCI for collecting uplink positioning training data is scrambled by a corresponding RNTI (such as defined as UTDC-RNTI), and the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI for collecting uplink positioning training data is divided into multiple blocks, each block corresponds to control information of a group of terminal devices, and there is at least one of the following fields in the block: the first information field, the second information field, or the third information field. The first information field indicates a set of SRS resources that need to be activated for the corresponding terminal device group. The second information field indicates whether the terminal device needs to report label data, occupies 1 bit, and bit 0 represents not reporting label data, and bit 1 represents reporting label data, or the opposite meaning is adopted. The third information field indicates whether the terminal device needs to report the quality of the label data, occupies 1 bit, and 0 represents not reporting the quality information of the label data, and 1 represents reporting the quality information of the label data.

[0343] It should be noted that the number of information bits transmitted in the group common DCI for collecting uplink positioning training data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted by the group common DCI for collecting uplink positioning training data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero needs to be filled at the end of the information bits of the group common DCI for collecting uplink positioning training data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group common DCI for collecting uplink positioning training data, the terminal device decodes the information bits of the group common DCI for collecting uplink positioning training data by blind detection, and the position index of the first bit of the block corresponding to the terminal device in the DCI is indicated by a high-level parameter.

[0344] In another possible implementation, the first indication information is a group common DCI for collecting training data, and the first indication information includes one or more of the following: a first information field, a second information field, or a third information field. The first information field is used to indicate a SRS resource set activated by the terminal device. The second information field is used to indicate whether the terminal device sends label data to the first access network device. The third information field is used to indicate whether the terminal device reports quality information of the label data to the first access network device, and the quality information of the label data is used to represent the accuracy of the label data.

[0345] For example, the group common DCI for collecting training data is scrambled by a corresponding RNTI (such as TDC-RNTI), and the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI for collecting training data is divided into multiple blocks, each block corresponds to the control information of a group of terminal devices, and the fields present in the block are explicitly indicated and / or implicitly indicated by a first higher layer parameter. For the terminal device of uplink positioning, the explicit indication is that the first higher layer parameter indicates uplink AI positioning, and the implicit indication is that the terminal device is pre-configured with SRS related configuration, and at least one of the following fields is present in the block: the first information field, the second information field, or the third information field, wherein the first information field indicates the SRS resource set that needs to be activated for the corresponding terminal device group. The second information field indicates whether the terminal device needs to report label data, and occupies 1 bit, 0 represents not reporting label data, and 1 represents reporting label data. The third information field indicates whether the terminal device needs to report quality information of the label data, and occupies 1 bit, 0 represents not reporting quality information of the label data, and 1 represents reporting quality information of the label data.

[0346] It should be noted that the number of information bits transmitted in the group common DCI for collecting training data is not greater than the number of bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI for collecting training data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI for collecting training data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group DCI, the terminal device obtains the information bits of the group common DCI for collecting training data through blind decoding, wherein the position index of the first bit of the block corresponding to the terminal device in the group common DCI for collecting training data is indicated by a higher layer parameter, and the terminal device receives the first higher layer parameter indicating uplink AI positioning and / or pre-configured SRS related configuration to determine that at least one of the following fields is present in the block: the first information field, the second information field, and the third information field.

[0347] Optionally, although not shown in FIG. 11, the communication method provided by the embodiments of the present application further includes: the first access network device sends a first high-layer parameter to the terminal device, and the first high-layer parameter is used to indicate that the second indication information is used to collect uplink positioning training data.

[0348] It should be understood that although not shown in FIG. 11, S1120 can be replaced by: the terminal device sends label data and / or SRS to the first access network device according to the configuration information used to collect training data, the first indication information, and the first high-layer parameter. Correspondingly, the first access network device receives the label data and / or SRS from the terminal device.

[0349] Optionally, as shown in FIG. 11, the communication method provided by the embodiments of the present application further includes:

[0350] S1170, the first access network device sends the second indication information to the terminal device. Correspondingly, the terminal device receives the second indication information from the terminal device.

[0351] In the embodiments of the present application, the second indication information is used to indicate that the terminal device sends SRS to one or more second access network devices, and / or sends monitored label data to the first access network device. The monitored label data is used to monitor the AI model performance.

[0352] In the monitoring link, in one possible implementation manner, the terminal device sends monitoring data to the first access network device, in another possible implementation manner, the terminal device does not report monitoring data while sending SRS, and in still another possible implementation manner, the terminal device only reports monitoring data.

[0353] It should be noted that the reporting of the monitored label data while sending SRS is applicable to the case where the monitoring data is provided by the terminal device sending SRS, the reporting of the monitoring data while sending SRS is applicable to the case where the monitoring data is provided by a network side device (such as a positioning management function network element), and the reporting of only the monitored label data is applicable to the case where the data provided by surrounding terminal devices is used as monitoring data and / or auxiliary information, and is also applicable to the case where the positioning management function network element monitors the gNB side model and the monitoring data is provided by the terminal device. Therefore, the first access network device can group the terminal devices according to the above different cases, and instruct the terminal devices to send SRS and / or report monitoring data.

[0354] In a possible implementation, the second indication information is a group common DCI for collecting the uplink positioning monitoring data. The second indication information includes one or more of the following: a fourth information field, a fifth information field, or a sixth information field. The fourth information field is used to indicate a set of SRS resources activated by the terminal device; the fifth information field is used to indicate whether the terminal device reports label data to the first access network device; and the sixth information field is used to indicate whether the terminal device reports quality information of the label data to the first access network device, the quality information of the label data being used to represent accuracy of the label data.

[0355] It should be understood that although not embodied in FIG. 11, S1120 can be replaced with: the terminal device sends monitoring data and / or SRS to the first access network device according to the configuration information for collecting the training data and the second indication information.

[0356] For example, the group common DCI for collecting the uplink positioning monitoring data is scrambled by a corresponding RNTI (such as defined as UMDC-RNTI), where the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI for collecting the uplink positioning monitoring data is divided into multiple blocks, each block corresponding to control information of a group of terminal devices, and each block includes at least one of the following fields: the fourth information field, the fifth information field, or the sixth information field. The fourth information field indicates a set of SRS resources that need to be activated by the corresponding group of terminal devices. The fifth information field occupies 1 bit, where 0 indicates that no label data is reported, and 1 indicates that label data is reported. The sixth information field indicates whether the terminal device needs to report quality information of the label data, and occupies 1 bit, where 0 indicates that no quality information of the label data is reported, and 1 indicates that quality information of the label data is reported.

[0357] It should be noted that the number of information bits transmitted in the group common DCI for collecting the uplink positioning monitoring data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted by the group common DCI for collecting the uplink positioning monitoring data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI for collecting the uplink positioning monitoring data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and the common search space corresponding to the group DCI, the terminal device decodes the information bits of the group DCI by blind detection, where the first bit of the block corresponding to the terminal device is indicated by a high-level parameter.

[0358] In another possible implementation, the second indication information is a group common DCI for collecting the monitoring data. The second indication information includes one or more of the following: a fourth information field, a fifth information field, or a sixth information field; the fourth information field is used to indicate a set of SRS resources activated by the terminal device; the fifth information field is used to indicate whether the terminal device reports label data to the first access network device; and the sixth information field is used to indicate whether the terminal device reports quality information of the label data to the first access network device, the quality information of the label data being used to represent accuracy of the label data.

[0359] Optionally, although not shown in FIG. 11, the communication method provided in the embodiments of the present application further includes: the first access network device sends a second high-layer parameter to the terminal device. Correspondingly, the terminal device receives the second high-layer parameter from the first access network device.

[0360] The second high-layer parameter is used to indicate that the second indication information is used to collect uplink positioning monitoring data.

[0361] It should be understood that, although not shown in FIG. 11, S1120 can be replaced with: the terminal device sends monitoring data and / or SRS to the first access network device according to the configuration information for collecting training data, the second indication information, and the second high-layer parameter. Correspondingly, the first access network device receives the monitoring data and / or SRS from the terminal device.

[0362] For example, the group common DCI for collecting the monitoring data is scrambled by a corresponding RNTI (such as defined as MDC-RNTI), wherein the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI for collecting the monitoring data is divided into multiple blocks, each block corresponds to control information of a group of terminal devices, and the fields present in the block are explicitly indicated and / or implicitly indicated by the second high-layer parameter. For the terminal device for uplink positioning, the explicit indication is that the high-layer parameter indicates uplink AI positioning, and the implicit indication is that the terminal device is pre-configured with SRS related configuration, and at least one of the following fields is present in the block: the fourth information field, the fifth information field, and the sixth information field. The fourth information field indicates a set of data collection SRS resources that need to be activated for the corresponding terminal device group. The fifth information field indicates whether the terminal device needs to report label data, occupies 1 bit, 0 represents not reporting label data, and 1 represents reporting label data. The sixth information field indicates whether the terminal device needs to report quality of the label data, occupies 1 bit, 0 represents not reporting quality information of the label data, and 1 represents reporting quality information of the label data.

[0363] It should be noted that the number of information bits transmitted in the group common DCI for collecting monitoring data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI for collecting monitoring data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group DCI until the number of bits is consistent with the DCI format 1_0. After receiving the RNTI and the common search space corresponding to the group common DCI for collecting monitoring data configured by the RRC signaling of the terminal device, the terminal device decodes the information bits of the group common DCI for collecting monitoring data through blind decoding. The position index of the first bit of the block corresponding to the terminal device in the group common DCI for collecting monitoring data is indicated by the high-level parameter. Meanwhile, the terminal device receives the second high-level parameter indicating the uplink AI positioning and / or the SRS related configuration configured in advance to determine whether there is at least one of the following domains in the block: the fourth information domain, the fifth information domain, and the sixth information domain.

[0364] Optionally, as shown in FIG. 12, step S1160 or step S1170 can be replaced by:

[0365] S1280, the first access network device sends third indication information to the terminal device. Correspondingly, the terminal device receives the third indication information from the first access network device.

[0366] In the embodiments of the present application, the first indication information is used to instruct the terminal device to send SRS to one or more second access network devices, and / or to send first data to the first access network device. The first data includes one or more of the following: label data for training, or label data for monitoring, and the label data for monitoring is used to monitor the performance of the AI model.

[0367] In a possible implementation, the third indication information is a group common DCI for collecting uplink positioning first data. The third indication information includes one or more of the following: a seventh information domain, an eighth information domain, or a ninth information domain; wherein the seventh information domain is used to indicate the SRS resource set activated by the terminal device; the eighth information domain is used to indicate whether the terminal device reports the first data to the first access network device; and the ninth information domain is used to indicate whether the terminal device reports the quality information of the first data to the first access network device, and the quality information of the first data is used to represent the accuracy of the label data.

[0368] It should be understood that although not embodied in FIG. 11, S1120 can be replaced with: the terminal device sends first data and / or SRS to the first access network device according to the configuration information for collecting training data and the third indication information. Correspondingly, the first access network device receives the first data and / or SRS from the terminal device.

[0369] For example, the group common DCI for collecting the first uplink positioning data is scrambled by a corresponding RNTI (such as defined as UDC-RNTI), where the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI for collecting the first uplink positioning data is divided into multiple blocks, each block corresponding to the control information of a group of terminal devices, and there is at least one of the following domains in the block: a seventh information domain, an eighth information domain, and a ninth information domain, where the seventh information domain indicates the SRS resource set that needs to be activated for the corresponding terminal device group. The eighth information domain indicates whether the terminal device needs to report the tag data, occupying 1 bit, where 0 represents not reporting the tag data and 1 represents reporting the tag data; the ninth information domain indicates whether the terminal device needs to report the quality information of the tag data, occupying 1 bit, where 0 represents not reporting the quality information of the tag data and 1 represents reporting the quality information of the tag data.

[0370] It should be noted that the number of information bits transmitted in the group common DCI for collecting the first uplink positioning data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted by the group common DCI for collecting the first uplink positioning data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group DCI until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and the common search space corresponding to the group common DCI for collecting the first uplink positioning data, the terminal device decodes the information bits of the group common DCI for collecting the first uplink positioning data through blind detection, where the position index of the first bit of the block corresponding to the terminal device in the group common DCI for collecting the first uplink positioning data is indicated by a high-level parameter.

[0371] In another possible implementation, the third indication information is a group common DCI for collecting the first data. The third indication information includes one or more of the following: a seventh information domain, an eighth information domain, or a ninth information domain; where the seventh information domain is used to indicate the SRS resource set activated by the terminal device; the eighth information domain is used to indicate whether the terminal device reports the first data to the first access network device; and the ninth information domain is used to indicate whether the terminal device reports the quality information of the first data to the first access network device, where the quality information of the first data is used to represent the accuracy of the tag data.

[0372] For example, the group common DCI for collecting the first data is scrambled by a corresponding RNTI (such as defined as DC-RNTI), wherein the value range of the RNTI is 0001-FFF2. The information transmitted by the group common DCI for collecting the first data is divided into multiple blocks, each block corresponds to the control information of a group of terminal devices, and the fields present in the block are explicitly indicated and / or implicitly indicated by a high-level parameter. For the terminal device for uplink positioning, the explicit indication is that a third high-level parameter indicates uplink AI positioning, and the implicit indication is that the terminal device is pre-configured with SRS related configuration, and at least one of the following fields is present in the block: a seventh information field, an eighth information indication field, or a ninth information field, wherein the seventh information field indicates a set of SRS resources that need to be activated for the corresponding terminal device group. The eighth information field indicates whether the terminal device needs to report tag data, occupies 1 bit, 0 represents not reporting tag data, and 1 represents reporting tag data; the ninth information field indicates whether the terminal device needs to report quality information of the tag data, occupies 1 bit, 0 represents not reporting quality information of the tag data, and 1 represents reporting quality information of the tag data.

[0373] It should be noted that the number of information bits transmitted in the group common DCI for collecting the first data is not greater than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell. If the number of information bits transmitted in the group common DCI for collecting the first data is less than the number of information bits of the DCI format 1_0 monitored in the common search space of the same serving cell, zero padding is needed at the end of the information bits of the group common DCI for collecting the first data until the number of bits is consistent with the DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group DCI of the terminal device, the terminal device obtains the information bits of the group common DCI for collecting the first data by blind decoding, wherein the position index of the first bit of the block corresponding to the terminal device in the group common DCI for collecting the first data is indicated by a high-level parameter, and the terminal device receives a third high-level parameter indicating uplink AI positioning and / or pre-configured SRS related configuration to determine that at least one of the following fields is present in the block: the seventh information field, the eighth information field, or the ninth information field.

[0374] Optionally, although Figure 11 does not embody it, the communication method provided by the embodiments of the present application further includes: the first access network device sends a third high-level parameter to the terminal device, and the third high-level parameter is used to indicate that the third indication information is used to collect uplink positioning training data.

[0375] It should be understood that although not embodied in FIG. 11, S1120 can be replaced with: the terminal device sends first data and / or SRS to the first access network device according to the configuration information for collecting training data, the third indication information, and the third high-layer parameter. Correspondingly, the first access network device receives the first data and / or SRS from the terminal device.

[0376] Optionally, as shown in FIG. 13, step S1160, or step S1170, or step S1280 can be replaced with:

[0377] S1390, the first access network device sends fourth indication information to the terminal device. Correspondingly, the terminal device receives the fourth indication information from the first access network device.

[0378] In the embodiments of the present application, the fourth indication information is used to indicate the SRS resource set activated by the terminal device.

[0379] In the case where multiple terminal devices are configured with SRS configuration information and triggered SRS configuration information, interference between SRSs is easily caused, so the terminal devices can be configured in groups and instructed to send SRSs in batches. In addition, data collection and model training for terminal devices under the same conditions (such as the same terminal device Tx TEG and the same scenario) can improve the fitting degree of the trained model, thereby improving the accuracy of AI positioning, so it is also necessary to configure corresponding SRSs for terminal devices in groups to complete the training of various models.

[0380] In a possible implementation manner, the fourth indication information is DCI format 2_3.

[0381] For example, for a common DCI format 2_3, the terminal device is configured with a high-layer parameter srs-TPC-PDCCH-Group = typeB, and the position index of the first bit of the block corresponding to the terminal device in the DCI is indicated by a high-layer parameter. There is an SRS request field in the block, which indicates the SRS resource set that needs to be activated by the terminal device. This field can refer to the case without configuration of a serving cell auxiliary uplink in Embodiment 4. In order to avoid mutual interference of SRSs sent by terminal devices in the group, the SRS resource sets of each terminal device activated by the value of the SRS request field should not overlap in the time-frequency domain or be orthogonal in the code domain.

[0382] In another possible implementation manner, the fourth indication information is a group-common DCI for collecting training data.

[0383] Exemplarily, the group common DCI for collecting training data is scrambled by a corresponding RNTI (such as defined as DC-RNTI), wherein the RNTI has a value range of 0001-FFF2. The information transmitted by the group DCI is divided into multiple blocks, each block corresponds to the control information of a group of terminal devices, and there is an SRS request field in the block, which has at least one of the following forms:

[0384] The first form: for terminal devices not configured by a higher layer with a service cell supplementary uplink, the field indicates a set of data collection SRS resources that need to be activated, such as the field occupying 2 bits, different bit strings corresponding to the required activated data collection SRS resource set are shown in Table 2; for terminal devices configured by a higher layer with a service cell supplementary uplink, one bit in the field indicates whether to transmit SRS on the supplementary uplink, and the remaining bits indicate a set of data collection SRS resources that need to be activated, such as the remaining 2 bits, different bit strings corresponding to the required activated SRS resource set are shown in Table 2.

[0385] The second form: for terminal devices not configured by a higher layer with a set of SRS resources of resource type aperiodic scheduling, the field occupies 0 bits; for terminal devices configured by a higher layer with a set of SRS resources of resource type aperiodic scheduling, the form of the field is the same as the first form.

[0386] It should be noted that, in order to avoid mutual interference of SRS transmitted by terminal devices in the group, the SRS resource set of each terminal device activated by the value of the SRS request field should not overlap in the time-frequency domain or be orthogonal in the code domain. The number of information bits transmitted in the group DCI is not greater than the number of information bits of DCI format 1_0 monitored in the common search space of the same service cell. If the number of information bits transmitted by the group DCI is less than the number of information bits of DCI format 1_0 monitored in the common search space of the same service cell, zero padding is needed at the end of the information bits of the group DCI until the number of bits is consistent with DCI format 1_0. After receiving the RRC signaling configured RNTI and common search space corresponding to the group DCI of the terminal device, the information bits of the group DCI are obtained by blind detection, wherein the position index of the first bit of the block corresponding to the terminal device in the DCI is indicated by a higher layer parameter.
