Description

Data collection method, device and communication equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on January 31, 2024, with application number 202410138097.6 and application name “Data Collection Method, Device and Communication Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a data collection method, apparatus, and communication equipment. Background Art

[0003] Artificial Intelligence (AI) and Machine Learning (ML) have demonstrated remarkable capabilities in internet-based fields such as image and speech recognition. The capabilities of AI / ML in wireless communication systems are also being explored. For positioning, in direct AI / ML positioning, the AI / ML model directly outputs the location of the user equipment (UE), while in AI / ML-assisted positioning, the model outputs intermediate measurements such as time of arrival (ToA).

[0004] The input of the AI / ML model may be determined based on a dynamic transmission-reception point (TRP) combination (dynamic TRP pattern). When the UE / location management function (LMF) collects data for the model, it needs to collect a large amount of training data. Without knowing the prior information of the dynamic TRP combination, the LMF may configure more TRPs to send downlink positioning reference signals (DL-PRS) and / or configure more TRPs to measure the uplink sounding reference signals (UL-SRS) sent by the UE, resulting in some TRPs sending DL-PRS or some TRPs measuring UL-SRS results being useless, resulting in a waste of air interface resources and information transmission resources.

[0325] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0326] When describing the embodiments of the present disclosure, some concepts used in the following description are first explained.

[0327] 1. AI / ML Model

[0328] When the AI / ML model performs inference, the input of the model can be the channel-related information obtained by the UE after measuring the DL-PRS sent by the TRP; or the input of the model can be the channel-related information obtained after the TRP measures the uplink sounding reference signal position (UL-SRS-Position, UL-SRS-pos) sent by the UE. As shown in Figure 1, the channel-related information includes: Channel Impulse Response (CIR), Channel Frequency Response (CFR), Power Delay Profile (PDP), Delay Profile (DP), etc. The output of the model can be the UE position or an intermediate quantity used to determine the UE position.

[0329] 2. AI / ML Positioning Solutions

[0330] (1) Based on UE positioning, AI / ML models are deployed on the UE side to achieve direct AI / ML positioning or AI / ML-assisted positioning;

[0331] (2) Based on UE-assisted / LMF positioning, AI / ML models are deployed on the UE side to achieve AI / ML-assisted positioning;

[0332] (3) Based on UE-assisted / LMF positioning, AI / ML models are deployed on the LMF side to achieve direct AI / ML positioning;

[0333] (4) Next Generation Radio Access Network (NG-RAN) node-assisted positioning, deploying AI / ML models on the next Generation Node B (gNB) side of the fifth-generation mobile communication technology (5G) to achieve AI / ML-assisted positioning;

[0334] (5) NG-RAN node assisted positioning, deploying AI / ML models on the LMF side to achieve direct AI / ML positioning.

[0335] The models of solutions (1) and (2) are deployed on the UE side, and the output of the models is an intermediate quantity used to determine the UE location (for AI / ML-assisted positioning, the output of the model can be ToA, Reference Signal Time Difference (RSTD), etc.), or the output of the model is the UE location. The model of solution (4) is deployed on the gNB / TRP side, and the output of the model is an intermediate quantity used to determine the UE location.

[0336] For the UE-side models of scheme (1) and scheme (2), the number of TRPs measured by the UE can be multiple TRPs, for example: 18 TRPs. The UE can obtain the channel-related information corresponding to the 18 TRPs through the DL-PRSs sent by the 18 TRPs respectively. The input of the model is determined based on the channel-related information corresponding to the 18 TRPs obtained by the UE.

[0337] If the TRP corresponding to the channel-related information of the model input is the same in all the data of the training model, it can be called a fixed TRP pattern. For example, the input of the model of all the training data is determined by the channel-related information corresponding to the fixed 18 TRPs. The UE may also measure the DL-PRS sent by some of the 18 TRPs for the following reasons to obtain the corresponding channel-related information and determine the input of the model. At this time, among all the data of the training model, some of the 18 TRPs corresponding to the model input of different data may be different, that is, in the training data of the model, there are multiple TRP patterns (some of the 18 TRPs constitute the TRP pattern) to obtain the channel-related information to determine the input of the model. In this case, the TRP corresponding to the channel-related information of the model input may change, which can be called a dynamic TRP pattern.

[0338] The reason why the UE measures the dynamic TRP pattern to obtain channel-related information may be:

[0339] 1) Impact of network energy saving, for example, a TRP cannot send DL-PRS for energy saving;

[0340] 2) Provide flexibility to the base station. For example, when some TRPs in TRP pattern 1 cause severe interference when sending DL-PRS, the base station can send DL-PRS according to TRP pattern 2.

[0341] 3) The measurement results of some TRPs among the 18 TRPs measured by the UE may have large interference and poor signal quality.

[0342] For the gNB-side model of solution (4), similar to the UE-side model, the model input can be determined based on the UL-SRS-pos transmitted by the UE measured at multiple TRPs. For all data trained on the model, the TRPs corresponding to the channel-related information input to the model can be the same or different. That is, the gNB-side model input can be determined based on the UL-SRS-pos channel-related information obtained from the TRP corresponding to the fixed TRP pattern or the dynamic TRP pattern.

[0343] For the LMF side model of solution (3), the input of the model can be determined based on the channel-related information corresponding to the DL-PRS sent by multiple TRPs measured by the UE. For the LMF side model of solution (5), the input of the model can be determined based on the channel-related information corresponding to the UL-SRS-pos sent by the UE measured by multiple TRPs. Regardless of solution (3) or solution (5), for all data of the training model, the TRP corresponding to the channel-related information input to the model may be the same or different, that is, the input of the LMF side model may be determined based on the DL-PRS channel-related information obtained by the UE corresponding to the fixed TRP pattern or the dynamic TRP pattern, or the UL-SRS-pos channel-related information obtained by the TRP.

[0344] Embodiments of the present disclosure provide a data collection method, apparatus, and communication device to address the problem of resource waste during data collection for AI / ML models.

[0345] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0346] As shown in FIG2 , an embodiment of the present disclosure provides a data collection method, which is applied to a first device and specifically includes the following steps:

[0347] Step 201: A first device sends first indication information to a second device, where the first indication information is used to instruct a first node in a first set to send and / or measure a reference signal;

[0348] Step 202: The first device receives feedback information sent by the second device, where the feedback information is determined based on a measurement result of a reference signal sent and / or measured by the first node;

[0349] The feedback information includes at least one of the following:

[0350] measurement results corresponding to some or all of the first nodes in the first set;

[0351] the order and / or identification of some or all of the first nodes in the first set;

[0352] The second device expects information about the first node.

[0353] In this embodiment, the first device may be an LMF or a third-party entity, and the second device may be one or more of a terminal, a base station, and a TRP. The first set includes multiple first nodes, each of which can be used to send and / or receive a reference signal. If the first node is, for example, a TRP, then the first set is a TRP set. The first device sends first indication information to the second device, where the first indication information is used to notify the second device that the first node in the first set sends a reference signal and / or that the first node in the first set measures a reference signal.

[0354] In some embodiments, taking the first node being a TRP and the second device being a terminal as an example, the first device sends a first indication message to the terminal, instructing the TRP in the first set to send a downlink positioning reference signal (DL-PRS). The terminal can measure the DL-PRS to obtain a measurement result, and send feedback information to the first device based on the measurement result.

[0355] In some embodiments, taking the first node as a TRP and the second device as a base station as an example, the first device sends a first indication message to the base station, instructing the TRP in the first set to measure the uplink positioning reference signal (UL-SRS-pos) sent by the terminal, and the TRP in the first set measures the UL-SRS-pos and obtains the measurement results. The base station can send feedback information to the first device based on the measurement results.

[0356] In some embodiments, taking the first node being a TRP and the second device being a TRP as an example, the first device sends a first indication message to the TRP, instructing the TRP in the first set to measure the UL-SRS-pos sent by the terminal, the TRP in the first set measures the UL-SRS-pos and obtains the measurement result, and sends feedback information to the first device based on the measurement result.

[0357] The feedback information may include measurement results corresponding to some or all first nodes in the first set, wherein the measurement result may be a measurement result corresponding to a reference signal sent by the first node, or a measurement result obtained by the first node measuring the reference signal.

[0358] And / or, the feedback information may include the ranking and / or identification of some or all of the first nodes in the first set. The ranking (and / or identification) may be the ranking (and / or identification) of each first node determined by the second device itself, or the ranking (and / or identification) of some nodes fed back by the second device based on the ranking (and / or identification) indicated by the first device.

[0359] And / or, the feedback information may include information about the first node expected by the second device. The first node expected by the second device may include some or all of the nodes in the first set, and may also include other first nodes outside the first set. The first node expected by the second device may be determined by the second device based on historical experience, or may be the optimal node determined by the second device based on signal measurement results.

[0360] After receiving the feedback information sent by the second device, the first device can determine the node for sending and / or measuring the reference signal based on the feedback information, thereby avoiding wasting resources due to configuring too many nodes and / or measuring unnecessary signals.

[0361] In an embodiment of the present disclosure, a first device sends first indication information to a second device, instructing a first node in a first set to send and / or measure a reference signal, so that the second device measures and / or sends a reference signal at a corresponding position based on the indication information and sends feedback information to the first device. The feedback information may include the measurement results, sorting, identification and / or information of the first nodes expected by the second device of each first node in the first set, so that the first device can configure a suitable network node to send and / or measure the reference signal based on the feedback information, thereby avoiding the waste of resources caused by configuring redundant nodes, and also avoiding the waste of resources caused by the second device measuring unnecessary reference signals.

[0362] As an optional embodiment, the method further includes:

[0363] determining a second set according to the feedback information;

[0364] Sending second indication information to the second device, where the second indication information is used to instruct the first node in the second set to send and / or measure a reference signal;

[0365] The first nodes included in the second set are at least partially identical to the first nodes included in the first set.

[0366] In this embodiment, the first device can determine the reference signal sent and / or measured by the first node in the second set based on the feedback information of the second device, and the measurement results corresponding to the reference signal sent and / or measured by the first node in the second set can be used to determine channel-related information, and then determine the input of the model and / or function used for positioning.

[0367] For example: the first device selects some first nodes as the second set based on the measurement results, identifications and sorting corresponding to the first nodes in the first set, and the first nodes in the second set send and / or measure reference signals. The second device determines channel-related information as input to the positioning model and / or function based on the measurement results of the first nodes in the second set sending and / or measuring the reference signals, thereby avoiding waste of resources.

[0368] For another example: the first device selects some of the first nodes in the first set as the second set based on the first node expected by the second device, and the first nodes in the second set send and / or measure reference signals. The second device determines channel-related information as input to the positioning model and / or function based on the measurement results of the first nodes in the second set sending and / or measuring the reference signals, thereby avoiding waste of resources.

[0369] It should be noted that the first nodes expected by the second device may all be nodes in the first set or some of the nodes in the first set. The nodes included in the second set may all be nodes in the first set or some of the nodes in the first set.

[0370] In some embodiments, the number of first nodes included in the first set is greater than or equal to the number of first nodes included in the second set;

[0371] and / or,

[0372] The second set is a subset of the first set.

[0373] For example, the first set includes 10 first nodes with indexes from 1 to 10, and the first device determines, based on feedback information from the second device, that the first nodes with indexes from 1 to 5 constitute the second set. For another example, the first set includes 10 first nodes with indexes from 1 to 10, and the first device determines, based on feedback information from the second device, that the first nodes with indexes from 1 to 5 in the first set and the first nodes with indexes from 11 to 15 expected by the second device constitute the second set.

[0374] In some embodiments, the first node in the first set sends and / or measures a reference signal at a first time; and / or the first node in the second set sends and / or measures a reference signal at a second time.

[0375] In this embodiment, the first time and the second time are different. The first indication information sent by the first device to the second device may instruct the first node in the first set to send and / or measure the reference signal at the first time. The second indication information sent by the first device to the second device may instruct the first node in the second set to send and / or measure the reference signal at the second time.

[0376] In some embodiments, the time format corresponding to the first time and / or the second time includes at least one of the following:

[0377] (1) Time period: The first time and / or the second time may be a time period, and the time period corresponding to the first time is different from the time period corresponding to the second time. The first time and / or the second time may be a time period within a cycle, and the time period corresponding to the first time within the cycle is different from the time period corresponding to the second time within the cycle.

[0378] (2) Time window; the first time and / or the second time may be a time window, and the time window corresponding to the first time is different from the time window corresponding to the second time.

[0379] (3) A target period in X periods, where X is a positive integer; the first time and / or the second time may be a period, specifically one of the X periods. For example, the LMF instructs the first node in the first set to send and / or measure a reference signal in the first period of four periods. In some embodiments, the same period may include both the first time and the second time, but the first time and the second time correspond to different time ranges.

[0380] (4) Time determined according to the transmission period of the reference signal. The first time and / or the second time may be determined according to the transmission period of the reference signal, for example, the first time is related to the transmission period of the DL-PRS, and the second time is related to the transmission period of the UL-SRS-pos.

[0381] As an optional embodiment, the method further includes:

[0382] Send third indication information to the second device, where the third indication information is used to indicate time-related information corresponding to the first time and / or the second time, where the time-related information includes at least one of the following:

[0383] 1) The time range of the time period; the time period may be a time period within a cycle, for example, the first time is a time period within the first time range within a certain cycle.

[0384] 2) The time range of the time window; the time window may be a time window within a cycle, for example, the second time is a time window of a second time range within a certain cycle.

[0385] 3) the value of X;

[0386] 4) The identifier of the target period; it may be a value of the target period, for example: the first period, the second period, etc., or period 1, period 2, etc.;

[0387] 5) The length of a cycle;

[0388] 6) the starting position of the target cycle in the X cycles;

[0389] 7) The end position of the target cycle in the X cycles.

[0390] In this embodiment, the first device may send time-related information of the first time and / or time-related information of the second time to the second device. For example, if the first device instructs the TRP in the first set to send DL-PRS in the x1th period in X periods, the first device may indicate at least one of the following information: the value of X, the value of x1, the length of a period, and the starting and / or ending position of the x1th period in the X periods. X is greater than or equal to x1, preferably, x1=1.

[0391] For another example: when the first time and / or the second time is a time period or a time window, the first device can indicate a method for determining the time period or time window, for example: the first device instructs the TRP in the second set to measure UL-SRS-pos in a certain time period, and the first device can indicate the time range of the time period.

[0392] As an optional embodiment, the relationship between the first time and the second time includes at least one of the following:

[0393] (1) The duration corresponding to the second time is R times the duration corresponding to the first time, and R is greater than 0;

[0394] In this embodiment, R may be greater than or equal to 1, or may be less than 1, that is, the length of the second time may be greater than or equal to the first time, or may be less than the length of the first time. For example: the first device indicates that the second time is r times the first time, or the first time is r times the second time. Here, r may be greater than or equal to 1, or may be less than 1.

[0395] (2) The starting position of the second time is determined according to the ending position of the first time;

[0396] In this embodiment, the starting position of the second time can be determined based on the ending position of the first time. For example, the starting position of the second time is a period length (or a preset time length) after the ending position of the first time.

[0397] (3) The period corresponding to the second time is a period other than the period corresponding to the first time in the X periods.

[0398] In this embodiment, among the X cycles, other cycles except the cycle corresponding to the first time may be considered as target cycles corresponding to the second time.

[0399] In some embodiments, the method further includes: sending fourth indication information to the second device, where the fourth indication information is used to indicate: the relationship between the first time and the second time.

[0400] In this embodiment, the relationship between the first time and the second time may be determined by the second device itself, or may be pre-configured by the network side, or may be indicated by the first device to the second device.

[0401] In some embodiments, the information of the first node desired by the second device is determined according to at least one of the following indicators:

[0402] Reference signal received power RSRP;

[0403] Reference signal received quality RSRQ;

[0404] Quality indicator information;

[0405] Channel indication of line of sight LOS;

[0406] Channel indication for non-line-of-sight (NLOS)

[0407] In this embodiment, the second device may determine the desired first node based on the measurement result of the reference signal. For example, the second device is a UE, the first node is a TRP node, and the UE measures the DL-PRS sent by all TRPs in the first set to obtain a measurement value, where the measurement value includes at least one of the following: RSRP, quality indication information, LOS channel indication, and NLOS channel indication; the UE sorts the RSRPs of all TRPs in the first set and determines the optimal M TRPs as the desired TRPs, and the UE feeds back information about the optimal M TRPs to the first device.

[0408] For example, the second device is a gNB, the first node is a TRP node, and all TRPs in the first set measure UL-SRS-pos to obtain measurement values. The measurement values ​​include at least one of the following: RSRP, quality indicator information, LOS channel indicator, and NLOS channel indicator. The gNB sorts the RSRPs of all TRPs in the first set and determines the optimal N TRPs. The gNB then feeds back the optimal N TRPs to the first device.

[0409] In some embodiments, the information of the first node desired by the second device includes at least one of the following:

[0410] identifiers of N first nodes expected by the second device, where N is a positive integer;

[0411] an ordering of the N first nodes desired by the second device;

[0412] the priorities of the N first nodes desired by the second device;

[0413] The number of N first nodes expected by the second device; that is, the value of the number N;

[0414] M first node combinations expected by the second device, where M is a positive integer and the first node combination includes at least one of the first nodes; the first node combination expected by the second device may be determined by the second device based on a measurement result of the first node;

[0415] identifiers corresponding to the M first node combinations expected by the second device;

[0416] Among the candidate node combinations indicated by the first device, the second device expects P first node combinations, where P is a positive integer; the first device configures one or more candidate node combinations for the second device, and the second device selects the expected P first node combinations from the candidate node combinations;

[0417] Identifiers corresponding to P first node combinations expected by the second device among the candidate node combinations indicated by the first device;

[0418] S first node rankings expected by the second device, where S is a positive integer, and the first node rankings include a ranking of at least one of the first nodes; the first node ranking expected by the second device may be determined by the second device based on a measurement result of the first node;

[0419] Identifiers corresponding to the order of the S first nodes expected by the second device;

[0420] The second device expects T first node rankings from the candidate node rankings indicated by the first device, where T is a positive integer; the first device configures one or more candidate node rankings for the second device, and the second device selects the expected T first node rankings from the candidate node rankings;

[0421] In the candidate node ranking indicated by the first device, the identifiers corresponding to the T first node rankings expected by the second device.

[0422] In this embodiment, the "node combination" in the first node combination and candidate node combination refers to one or more first nodes, which can be grouped based on different parameters to form different node combinations. Taking the first node as a TRP as an example, the node combination can be expressed as a TRP combination (pattern).

[0423] As an optional embodiment, the method further includes:

[0424] Sending information of the candidate node combinations to the second device, where each candidate node combination is composed of at least one first node in the first set;

[0425] The candidate node combination information includes at least one of the following:

[0426] One or more first nodes corresponding to each candidate node combination;

[0427] The identifier corresponding to each candidate node combination.

[0428] In this embodiment, the first device may send information about one or more candidate node combinations to the second device. Each candidate node combination includes one or more first nodes. The first set may include multiple candidate node combinations. For example: the first device is LMF, the first node is TRP, LMF indicates one or more TRP pattern information included in the first set, and a TRP pattern may include one or more TRPs in the first set; it may also include a TRP pattern identifier corresponding to each TRP pattern.

[0429] As an optional embodiment, the method further includes:

[0430] Sending information about the candidate node rankings to the second device, where each candidate node ranking includes a ranking of at least one first node in the first set; wherein the information about the candidate node rankings includes at least one of the following:

[0431] One or more first nodes corresponding to each candidate node ranking;

[0432] The identifier corresponding to each candidate node ranking.

[0433] In this embodiment, the first device may send information about one or more candidate node rankings to the second device. Each candidate node ranking includes rankings of one or more first nodes. The first set may include multiple candidate node rankings.

[0434] As an optional embodiment, the sending the first indication information to the second device includes:

[0435] Sending first indication information to the second device every A cycles, where A is a positive integer;

[0436] The receiving feedback information sent by the second device includes:

[0437] Feedback information sent by the second device is received every B cycles, where B is a positive integer.

[0438] In this embodiment, the first device may instruct the first node in the first set to transmit and / or measure a reference signal every A cycles. The second device may send feedback information to the first device every B cycles. Preferably, B is equal to A. For example, the LMF instructs the TRP in the first set to transmit DL-PRS or measure UL-SRS-pos every A cycles, and the second device (one or more of the UE, gNB, and TRP) sends feedback information every A cycles.

[0439] As an optional embodiment, the method further includes:

[0441] The first node combination corresponding to the first node in the second set is at least one of the candidate node combinations corresponding to the first node in the first set.

[0442] In this embodiment, after the first device receives the feedback information sent by the second device, it can determine, based on the feedback information, that the first node combination included in the second set is at least one of the node combinations included in the first set. For example, the LMF can determine, based on the feedback information, that the TRP pattern included in the second TRP set is at least one of the TRP patterns in the first TRP set.

[0443] In an embodiment of the present disclosure, a first device instructs a second device to transmit and / or measure a reference signal at a first time. Upon receiving the instruction, the second device measures and / or transmits the reference signal at the first time, obtains measurement results for each first node in the first set, and sends feedback information to the first device based on the measurement results. The first set may be the entire set of first nodes, including some unnecessary nodes. Using the measurement results of all nodes as input for a positioning model and / or function would waste resources. Upon receiving the feedback information sent by the second device, the first device determines a second set based on the feedback information. The second set is determined based on node information expected by the second device and / or the measurement results, ranking, and / or identifiers of each node in the first set. Therefore, the first node in the second set is the optimal node that meets the second device's expectations. The first device sends a second instruction to the second device, instructing the first node in the second set to transmit and / or measure the reference signal at a second time. The second device may measure and / or transmit the reference signal at the second time, determine channel-related information based on the obtained measurement results, and further determine input for the positioning model and / or function.

[0444] Taking the first device as an LMF, the first node as a TRP, and the second device as a UE or a gNB as an example: the LMF instructs the TRPs in the entire TRP set to send DL-PRS or measure UL-SRS-pos, and the UE measures the DL-PRS sent by all TRPs in the entire TRP set to obtain measurement values ​​(such as RSRP, quality indication information, and LOS / NLOS channel indication), or all TRPs in the entire TRP set measure UL-SRS-pos to obtain measurement values ​​(such as RSRP, quality indication information, and LOS / NLOS channel indication), and the UE / gNB sorts the RSRPs of all TRPs in the entire TRP set and determines the optimal M TRPs (or TRP pattern), and the UE / gNB feeds back the optimal M TRPs (or TRP pattern) to the LMF; or, the UE / gNB feeds back the sorting and / or number of TRPs corresponding to all or part of the TRPs in the entire TRP set (which may be the number of the optimal M TRPs); or, the UE / gNB feeds back the RSRPs corresponding to all or part of the TRPs in the entire TRP set. In some embodiments, the LMF instructs the entire TRP set to send DL-PRS or measure UL-SRS-pos every A periods, and the UE / gNB feeds back the optimal TRP information every B periods.

[0445] The LMF determines a second set based on feedback from the UE / gNB within the next X-1 time periods / cycles, and instructs the TRPs in the second set to transmit DL-PRS or measure UL-SRS-pos. The UE / gNB determines channel-related information based on the measurement results of the DL-PRS or UL-SRS-pos transmitted by the TRPs in the second set. This channel-related information can be used to determine the input of the AI / ML model.

[0446] The following example illustrates an implementation method for determining input information for an AI / ML model based on the data collection method disclosed herein.

[0447] Example 1: Take the first device as LMF, the second device as UE, the first node as TRP, and the AI ​​model deployed on the UE side as an example.

[0448] Step 11: LMF sends a first indication message to the UE, instructing the TRP in the first set to send DL-PRS within the first time.

[0449] The first time may be a cycle, for example, LMF may instruct the TRP in the first set to send DL-PRS in the x1th cycle among X cycles; the first time may also be a time period, for example, LMF may instruct the TRP in the first set to send DL-PRS within a period of time.

[0450] The method for determining the first time may be related to the transmission period of DL-PRS, for example: LMF instructs the TRP in the first set to send DL-PRS within the period of Y DL-PRS resources or resource sets.

[0451] In some embodiments, the LMF may indicate the definition / value of the first time to the UE, for example:

[0452] When the first time is a period, the LMF indicates at least one of the following: the value of X in the X periods, the value of x1, the length of one period, and the start / end position of the x1 period in the X periods; where X is greater than or equal to x1, preferably x1=1;

[0453] When the first time is a time period / time window, the LMF may indicate a method for determining the time period, for example, the LMF may indicate a time range, a starting system frame number (SFN), an ending SFN, etc. of the time period. The time period may also be a time period within a cycle, and the LMF may indicate the length of the cycle, an offset of the time period within the cycle (a starting position offset and / or an ending position offset), the length of the time period, etc.

[0454] The first set includes one or more TRPs, and preferably the number of TRPs included in the first set is greater than or equal to the number of TRPs included in the second set.

[0455] The first set may include one or more TRP patterns. When the LMF indicates that the TRP in the first set sends the DL-PRS within the first time, it may also indicate one or more TRP pattern information included in the first set. A TRP pattern may include one or more TRPs in the first set.

[0456] The TRP pattern information indicated by the LMF may be a TRP identifier included in a TRP pattern. For example, the first set includes 10 TRPs, and the TRP identifiers are {0, 1, ..., 9}, respectively. The TRP identifiers of the TRPs included in TRP pattern 1 are {0, 1, 2}, the TRP identifiers of the TRPs included in TRP pattern 2 are {3, 4, 5}, and the TRP identifiers of the TRPs included in TRP pattern 3 are {6, 7, 8, 9}. When indicating one or more TRP pattern information included in the first set, the LMF may also include the TRP pattern identifier corresponding to each TRP pattern.

[0457] Step 12: The UE determines feedback information based on the DL-PRS sent by the TRP in the first set. The feedback information carries information related to one or more TRPs / TRP patterns. The TRP in the one or more TRPs / TRP patterns is the TRP in the first set. The UE sends feedback information to the LMF.

[0458] In some embodiments, the UE determines channel-related information based on the DL-PRS sent by the TRP in the first set, and the channel-related information can be used to determine the input of the AI ​​model. The input of the AI ​​model can be the DL-PRS channel-related information obtained by the UE measuring the DL-PRS signal sent by the TRP, and the channel-related information can be at least one of CIR, PDP, DP, RSRP, etc. Here, the TRP measured by the UE can be multiple, that is, the UE obtains the DL-PRS channel-related information corresponding to multiple TRPs by measuring the DL-PRS signals sent by multiple TRPs in the first set, and determines the input of the AI ​​model based on this. The output of the AI ​​model is the UE position or an intermediate quantity related to the position, and the intermediate quantity related to the position can be one or more of the time of arrival (ToA), angle of arrival (AoA), reference signal time difference (RSTD), RSRP, LOS / NLOS indicator, etc.

[0459] The UE determines the feedback information based on the DL-PRS sent by the TRP in the first set, further comprising: the UE measures the DL-PRS sent by the TRP in the first set to obtain measurement results corresponding to all TRPs or some TRPs, where the measurement results may be at least one of RSRP, signal-to-noise and interference ratio (SINR), quality indication information, and LOS / NLOS channel indication. The UE determines the feedback information based on the measurement results corresponding to all TRPs or some TRPs, where the feedback information carries information related to one or more TRPs / TRP patterns, where the TRPs in the one or more TRPs / TRP patterns are TRPs in the first set, and the feedback information may be at least one of the following:

[0460] 1) Measurement results of some / all TRPs in the first set, such as RSRP, SINR, etc.;

[0461] 2) TRP identifiers corresponding to the best N TRPs in the first set;

[0462] 3) The order of the best N TRPs in the first set. The feedback information may include the order of the best N TRPs according to a certain indicator (e.g., RSRP). For example, if N=4, the feedback information may include the order of the best four TRPs as TRP 1, TRP 5, TRP 3, and TRP 8.

[0463] 4) a ranking metric, ranking basis, or ranking method for the best N TRPs in the first set, such as ranking based on measurement quality indicators, ranking based on LOS / NLOS channel indicators from largest to smallest, or ranking based on RSRP from largest to smallest, etc.;

[0464] 5) The order of all TRPs in the first set. The feedback information may include the order of all TRPs according to a certain indicator (e.g., RSRP);

[0465] 6) The value of N for the best N TRPs in the first set;

[0466] 7) The optimal M TRP patterns consisting of some TRPs in the first set, each TRP pattern including one or more TRPs in the first set. The TRP pattern may be different from the one or more TRP pattern information indicated by the LMF in step 11. The UE may independently determine the number of TRPs included in a TRP pattern and the specific TRPs included;

[0467] 8) Identifiers corresponding to the optimal M TRP patterns formed by some TRPs in the first set.

[0468] 9) The best M TRP patterns among one or more candidate TRP patterns indicated by the LMF; the TRP pattern fed back by the UE needs to belong to one or more candidate TRP patterns indicated by the LMF, and the UE can feed back the TRP pattern identifier corresponding to each TRP pattern in the best M TRP patterns;

[0469] 10) The identifiers corresponding to the best M TRP patterns among one or more candidate TRP patterns indicated by LMF.

[0470] 11) An optimal S first node ranking consisting of a portion of the TRPs in the first set, where S is a positive integer, and the first node ranking includes a ranking of at least one first node;

[0471] 12) The identifiers corresponding to the optimal S first node rankings of the partial TRPs in the first set;

[0472] 13) The best T TRP rankings among one or more candidate TRP rankings indicated by LMF, where T is a positive integer;

[0473] 14) Identification of the best T TRP rankings among one or more candidate TRP rankings indicated by LMF.

[0474] In this embodiment, the optimal TRP / TRP pattern may be the TRP / TRP pattern expected by the UE, and may be determined by the UE based on historical experience or measurement results (such as RSRP).

[0475] Step 13: LMF determines the TRP in the second set to send DL-PRS within the second time based on the feedback information sent by the UE.

[0476] The second time is similar to the first time in definition. The second time may be a period. For example, the LMF may instruct the TRPs in the second set to send DL-PRS within the x2th period of X periods. The second time may also be a time period. For example, the LMF may also instruct the TRPs in the second set to send DL-PRS within the second time period. The determination of the second time may be related to the DL-PRS transmission period. For example, the LMF may instruct the TRPs in the second set to send DL-PRS within the period of Y1 DL-PRS resources / resource sets.

[0477] The LMF may indicate the definition / value of the second time to the UE, for example:

[0478] When the second time is a cycle, the LMF indicates at least one of the following: a value of x in X cycles, a value of x2, a length of a cycle, and a start / end position of the x2th cycle in the X cycles; where X is greater than or equal to x2, preferably x2 is greater than x1 and x2 is greater than 1;

[0479] When the second time is a time period / actual window, the LMF may indicate a method for determining the time period, for example, the LMF indicates the time range, the starting SFN, the ending SFN, etc. of the time period. The time period may also be a time period within a cycle (for example, the second time period), and the LMF indicates the length of the cycle, the offset of the time period in the cycle (the starting position offset and / or the ending position offset), the length of the time period, etc.

[0480] In some embodiments, LMF may further indicate the relationship between the second time and the first time. For example, LMF indicates that the second time is R times the first time, or the first time is R times the second time.

[0481] The LMF determines to send DL-PRS at the TRP in the second set at the second time based on the feedback information sent by the UE. In some embodiments, the LMF may determine, based on the feedback information, that the TRP pattern included in the second set is at least one of the TRP patterns in the first set; or, the TRP included in the second set is a subset of the TRP included in the first set. The LMF may know the TRP / TRP pattern in the first set that the UE prefers based on the feedback information fed back by the UE, so that the TRP in the second set indicated by the LMF at the second time to send DL-PRS is more preferred by the UE.

[0482] Step 14: The UE determines channel-related information based on the DL-PRS sent by the TRP in the second set, and the channel-related information can be used to determine the input of the AI ​​model.

[0483] In some embodiments, the second time is a relatively long time, and the LMF can instruct the TRP in the second set to send DL-PRS within a relatively long time. Since the second set is determined based on the feedback information of the UE, the TRP included in the second set is more needed or more preferred by the UE. The UE can determine the channel-related information based on the DL-PRS sent by the more preferred TRP, and determine the input of the AI ​​model based on the obtained channel-related information, so as to achieve the purpose of AI model data collection, avoid unnecessary information in the data collection process, and avoid waste of resources.

[0484] In this embodiment, the LMF transmits DL-PRS by instructing more TRPs included in the first set at the first time, so that the UE can determine the feedback information by measuring the DL-PRS sent by the TRP in the first set and send it to the LMF. Then, the LMF can instruct the second set including fewer TRPs to transmit DL-PRS at a relatively long second time, thereby saving the resource overhead of DL-PRS. However, due to reasons such as the mobility of the UE, the feedback information determined by the UE based on the DL-PRS sent by the TRP in the first set is not necessarily valid for a long time. The UE can send feedback information to the LMF at intervals. Assuming that the LMF instructs the TRP in the first set to transmit DL-PRS every A cycles, and the UE sends feedback information every B cycles, for example, the UE determines the feedback information based on the DL-PRS sent by the TRP in the first set within one cycle out of A cycles and sends it to the LMF, preferably A is equal to B.

[0485] In addition, in addition to the LMF periodically instructing the TRPs in the first set to send DL-PRS as described above, the LMF can also instruct the TRPs in the first set to send DL-PRS once. For example: in step 11, when the first time is a time point or a period of time, the LMF instructs the TRPs in the first set to send DL-PRS at a time point or within a period of time. The LMF can also instruct the TRPs in the first set to send DL-PRS in a semi-continuous manner. Here, the LMF instructs / activates the TRPs in the first set to send DL-PRS through indication information. The TRPs in the first set send DL-PRS according to a certain period or within a period of time. When the LMF instructs / deactivates the TRPs in the first set to send DL-PRS through indication information, the TRPs in the first set stop sending DL-PRS.

[0486] In addition to the periodic transmission of feedback information from the UE to the LMF as described above, the UE can also send feedback information once, and the timing of the UE sending the feedback information may depend on the instruction of the LMF. The UE can also send feedback information in a semi-continuous manner. Here, the LMF instructs / activates the UE to send feedback information through indication information. The UE sends feedback information to the LMF according to a certain period or within a period of time. When the LMF instructs / deactivates the UE to send feedback information through indication information, the UE stops sending feedback information.

[0487] In this embodiment, the LMF instructs the first set including more TRPs to send DL-PRS at the first time, so that the UE can determine the feedback information by measuring the DL-PRS sent by the TRP in the first set and send it to the LMF, and then the LMF can instruct the second set including fewer TRPs to send DL-PRS at a relatively long second time, thereby saving the resource overhead of DL-PRS.

[0488] Example 2: Take the case where the first device is an LMF, the second device is a gNB, the first node is a TRP, and the AI ​​model is deployed on the gNB side.

[0489] Step 21: The LMF instructs the TRP in the first set to measure UL-SRS-pos within the first time.

[0490] The first time may be a period, for example, the LMF may indicate that the TRP in the first set measures UL-SRS-pos within the x1th period of X periods. The first time may also be a time period, for example, the LMF may also indicate that the TRP in the first set measures UL-SRS-pos within a period of time. The manner of determining the first time may be related to the transmission period of UL-SRS-pos, for example, the LMF indicates that the TRP in the first set measures UL-SRS-pos within a period of Y UL-SRS-pos resources / resource sets.

[0491] The LMF may indicate the definition / value of the first time to the gNB. The content of the indication is similar to that in Example 1 and is not repeated here.

[0492] The first set may include one or more TRP patterns. When indicating the TRP measurement UL-SRS-pos in the first set within the first time, the LMF may also indicate one or more TRP pattern information included in the first set. A TRP pattern may include one or more TRPs in the first TRP set. Here, the TRP pattern information indicated by the LMF may be a TRP identifier included in a TRP pattern.

[0493] Step 22: The TRP in the first set measures the UL-SRS-pos sent by the UE to determine the feedback information, which carries information related to one or more TRPs / TRP patterns. The TRP in the one or more TRPs / TRP patterns is the TRP in the first TRP set; the gNB / TRP sends the feedback information to the LMF.

[0494] In some embodiments, the TRP in the first set measures the UL-SRS-pos sent by the UE to determine channel-related information, which can be used to determine the input of the AI ​​model.

[0495] The feedback information determined by measuring the UL-SRS-pos sent by the UE using the TRP in the first set also includes: obtaining measurement results corresponding to all or some TRPs using the UL-SRS-pos sent by the UE using the TRP in the first set, where the measurement results may be one or more of RSRP, SINR, quality indication information, and LOS / NLOS channel indication. The gNB / TRP determines feedback information based on the measurement results corresponding to all or some TRPs, where the feedback information carries information related to one or more TRPs / TRP patterns, where the TRPs in the one or more TRPs / TRP patterns are the TRPs in the first set. The content included in the feedback information is similar to that in Example 1 and is not further described here.

[0496] Step 23: The LMF determines the TRP measurement UL-SRS-pos in the second set within the second time based on the feedback information sent by the gNB / TRP.

[0497] The second time is defined similarly to the first time. The second time may be a period, for example, LMF may indicate that the TRP in the second set measures UL-SRS-pos within the x2th period in X periods. The second time may also be a time period, for example, LMF may also indicate that the TRP in the second set measures UL-SRS-pos within the second time period. The method for determining the second time may be related to the transmission period of UL-SRS-pos, for example, LMF indicates that the TRP in the second set measures UL-SRS-pos within the period of Y2 UL-SRS-pos resources / resource sets.

[0498] The LMF may indicate the definition / value of the second time to the gNB / TRP, similar to Example 1, and will not be further described here.

[0499] The LMF determines the TRP pattern measured UL-SRS-pos in the second set within the second time based on the feedback information sent by the gNB / TRP. The LMF may determine, based on the feedback information, that the TRP pattern included in the second set is at least one of the TRP patterns in the first set; or that the TRP included in the second set is a subset of the TRP included in the first set.

[0500] Step 24: The gNB / TRP measures the UL-SRS-pos sent by the UE based on the TRP in the second set to determine channel-related information, which can be used to determine the input of the AI ​​model.

[0501] In this embodiment, due to factors such as UE mobility, the feedback information determined by the gNB / TRP based on the UL-SRS-pos sent by the UE measured by the TRP in the first set is not necessarily valid in the long term. The gNB / TRP can send feedback information to the LMF at regular intervals.

[0502] In addition, in addition to the LMF periodically indicating that the TRP in the first set measures UL-SRS-pos, the LMF can also indicate the TRP in the first set to measure UL-SRS-pos once. For example, in step 21, when the first time is a time point or a period of time, the LMF indicates that the TRP in the first set measures UL-SRS-pos at a time point or a period of time. The LMF can also indicate that the TRP in the first set measures UL-SRS-pos in a semi-continuous manner. Here, the LMF indicates / activates the TRP in the first set to measure UL-SRS-pos through indication information. The TRP in the first set measures UL-SRS-pos according to a certain period or within a period of time. When the LMF indicates / deactivates the TRP in the first set to measure UL-SRS-pos through indication information, the TRP in the first set stops measuring UL-SRS-pos.

[0503] In addition to periodic feedback transmission from the gNB / TRP to the LMF, the gNB / TRP can also send feedback information once, depending on the instructions of the LMF. The gNB / TRP can also send feedback information semi-continuously. Here, the LMF instructs / activates the gNB / TRP to send feedback information through an indication message. The gNB / TRP sends feedback information to the LMF periodically or over a period of time. When the LMF instructs / deactivates the gNB / TRP to send feedback information through an indication message, the gNB / TRP stops sending feedback information.

[0504] In this embodiment, the LMF measures UL-SRS-pos at the first time by indicating more TRPs included in the first set, so that the gNB / TRP can determine the feedback information by measuring the UL-SRS-pos sent by the UE through the TRP in the first set and send it to the LMF, and then the LMF can indicate the second TRP set including fewer TRPs to measure UL-SRS-pos at a relatively long second time, saving unnecessary channel-related information of the TRP to determine the UL-SRS-pos.

[0505] In an embodiment of the present disclosure, a first device sends first indication information to a second device, instructing a first node in a first set to send and / or measure a reference signal, so that the second device measures and / or sends a reference signal at a corresponding position based on the indication information and sends feedback information to the first device. The feedback information may include the measurement results, sorting, identification and / or information of the first nodes expected by the second device of each first node in the first set, so that the first device can configure a suitable network node to send and / or measure the reference signal based on the feedback information, thereby avoiding the waste of resources caused by configuring redundant nodes, and also avoiding the waste of resources caused by the second device measuring unnecessary reference signals.

[0506] As shown in FIG3 , an embodiment of the present disclosure further provides a data collection method, which is applied to a second device and includes:

[0507] Step 301: A second device receives first indication information sent by a first device, where the first indication information is used to instruct a first node in a first set to send and / or measure a reference signal;

[0508] Step 302: The second device determines feedback information according to a measurement result of the reference signal sent and / or measured by the first node;

[0509] Step 303: The second device sends the feedback information to the first device;

[0510] The feedback information includes at least one of the following:

[0511] measurement results corresponding to some or all of the first nodes in the first set;

[0512] the order and / or identification of some or all of the first nodes in the first set;

[0513] The second device expects information about the first node.

[0514] In this embodiment, the first device may be an LMF or a third-party entity, and the second device may be one or more of a terminal, a base station, and a TRP. The first set includes multiple first nodes, each of which can be used to send and / or receive a reference signal. If the first node is, for example, a TRP, then the first set is a TRP set. The first device sends first indication information to the second device, where the first indication information is used to notify the second device that the first node in the first set sends a reference signal and / or that the first node in the first set measures a reference signal.

[0515] The second device sends a reference signal according to the first indication information and / or measures the reference signal sent by the first node to obtain a measurement result, determines feedback information based on the measurement result, and sends the feedback information to the first device, so that the first device determines the second set based on the feedback information.

[0516] In some embodiments, taking the first node being a TRP and the second device being a terminal as an example, the first device sends a first indication message to the terminal, instructing the TRP in the first set to send a downlink positioning reference signal (DL-PRS). The terminal can measure the DL-PRS to obtain a measurement result, and send feedback information to the first device based on the measurement result.

[0517] In some embodiments, taking the first node as a TRP and the second device as a base station as an example, the first device sends a first indication message to the base station, instructing the TRP in the first set to measure the uplink positioning reference signal (UL-SRS-pos) sent by the terminal, and the TRP in the first set measures the UL-SRS-pos and obtains the measurement results. The base station can send feedback information to the first device based on the measurement results.

[0518] In some embodiments, taking the first node being a TRP and the second device being a TRP as an example, the first device sends a first indication message to the TRP, instructing the TRP in the first set to measure the UL-SRS-pos sent by the terminal, the TRP in the first set measures the UL-SRS-pos and obtains the measurement result, and sends feedback information to the first device based on the measurement result.

[0519] The feedback information may include measurement results corresponding to some or all first nodes in the first set, wherein the measurement result may be a measurement result corresponding to a reference signal sent by the first node, or a measurement result obtained by the first node measuring the reference signal.

[0520] And / or, the feedback information may include the ranking (and / or identification) of some or all of the first nodes in the first set. The ranking (and / or identification) may be the ranking (and / or identification) of each first node determined by the second device itself, or the ranking (and / or identification) of some nodes fed back by the second device based on the ranking (and / or identification) indicated by the first device.

[0521] And / or, the feedback information may include information about the first node expected by the second device. The first node expected by the second device may include some or all of the nodes in the first set, and may also include other first nodes outside the first set. The first node expected by the second device may be determined by the second device based on historical experience, or may be the optimal node determined by the second device based on signal measurement results.

[0522] After receiving the feedback information sent by the second device, the first device can determine the node for sending and / or measuring the reference signal based on the feedback information, thereby avoiding wasting resources due to configuring too many nodes and / or measuring unnecessary signals.

[0523] In an embodiment of the present disclosure, a first device sends first indication information to a second device, instructing a first node in a first set to send and / or measure a reference signal. The second device measures and / or sends a reference signal at a corresponding position based on the indication information and sends feedback information to the first device. The feedback information may include the measurement results, sorting, identification and / or information of the first nodes expected by the second device of each first node in the first set, so that the first device can configure a suitable network node to send and / or measure the reference signal based on the feedback information, thereby avoiding the waste of resources caused by configuring redundant nodes, and also avoiding the waste of resources caused by the second device measuring unnecessary reference signals.

[0524] As an optional embodiment, the method further includes:

[0525] receiving second indication information sent by the first device, where the second indication information is used to instruct a first node in a second set to send and / or measure a reference signal;

[0526] determining channel-related information according to a measurement result of a reference signal sent and / or measured by the first node in the second set;

[0527] The second set is determined according to the feedback information, and the first nodes included in the second set are at least partially identical to the first nodes included in the first set.

[0528] In this embodiment, the first device can determine the reference signal sent and / or measured by the first node in the second set based on the feedback information of the second device, and the measurement results corresponding to the reference signal sent and / or measured by the first node in the second set can be used to determine channel-related information, and then determine the input of the model and / or function used for positioning.

[0529] For example: the first device selects some first nodes as the second set based on the measurement results, identifications and sorting corresponding to the first nodes in the first set, and the first nodes in the second set send and / or measure reference signals. The second device determines channel-related information as input to the positioning model and / or function based on the measurement results of the first nodes in the second set sending and / or measuring the reference signals, thereby avoiding waste of resources.

[0530] In some embodiments, the number of first nodes included in the first set is greater than or equal to the number of first nodes included in the second set; and / or, the second set is a subset of the first set.

[0531] For example, the first set includes 10 first nodes with indexes from 1 to 10, and the first device determines, based on feedback information from the second device, that the first nodes with indexes from 1 to 5 constitute the second set. For another example, the first set includes 10 first nodes with indexes from 1 to 10, and the first device determines, based on feedback information from the second device, that the first nodes with indexes from 1 to 5 in the first set and the first nodes with indexes from 11 to 15 expected by the second device constitute the second set.

[0532] In some embodiments, the first node in the first set sends and / or measures a reference signal at a first time; and / or the first node in the second set sends and / or measures a reference signal at a second time.

[0533] In this embodiment, the first time and the second time are different. The first indication information sent by the first device to the second device may instruct the first node in the first set to send and / or measure the reference signal at the first time. The second indication information sent by the first device to the second device may instruct the first node in the second set to send and / or measure the reference signal at the second time.

[0534] In some embodiments, the time format corresponding to the first time and / or the second time includes at least one of the following:

[0535] Time period;

[0536] Time window;

[0537] The target period in X periods, where X is a positive integer;

[0538] The time is determined according to the transmission period of the reference signal.

[0539] In some embodiments, the first time and / or the second time may be a time period within a cycle, and the time period corresponding to the first time within the cycle is different from the time period corresponding to the second time within the cycle.

[0540] As an optional embodiment, the method further includes:

[0542] the timeframe of the said period;

[0543] The time range of the time window;

[0544] the value of X;

[0545] an identifier of the target period;

[0546] The length of a cycle;

[0547] The starting position of the target cycle in the X cycles;

[0548] The target cycle is the end position of the X cycles.

[0549] In this embodiment, the first device may send time-related information of the first time and / or time-related information of the second time to the second device. For example, if the first device instructs the TRP in the first set to send DL-PRS in the x1th period in X periods, the first device may indicate at least one of the following information: the value of X, the value of x1, the length of a period, and the starting and / or ending position of the x1th period in the X periods. X is greater than or equal to x1, preferably, x1=1.

[0550] For another example: when the first time and / or the second time is a time period or a time window, the first device can indicate a method for determining the time period or time window, for example: the first device instructs the TRP in the second set to measure UL-SRS-pos in a certain time period, and the first device can indicate the time range of the time period.

[0551] As an optional embodiment, the relationship between the first time and the second time includes at least one of the following:

[0552] (1) The duration corresponding to the second time is R times the duration corresponding to the first time, and R is greater than 0;

[0553] In this embodiment, R may be greater than or equal to 1, or may be less than 1, that is, the length of the second time may be greater than or equal to the first time, or may be less than the length of the first time. For example: the first device indicates that the second time is r times the first time, or the first time is r times the second time. Here, r may be greater than or equal to 1, or may be less than 1.

[0554] (2) The starting position of the second time is determined according to the ending position of the first time;

[0555] In this embodiment, the starting position of the second time can be determined based on the ending position of the first time. For example, the starting position of the second time is a period length (or a preset time length) after the ending position of the first time.

[0556] (3) The period corresponding to the second time is a period other than the period corresponding to the first time in the X periods.

[0557] In this embodiment, among the X cycles, other cycles except the cycle corresponding to the first time may be considered as target cycles corresponding to the second time.

[0558] In some embodiments, the method further comprises:

[0559] Receive fourth indication information sent by the first device, where the fourth indication information is used to indicate: a relationship between the first time and the second time.

[0560] In this embodiment, the relationship between the first time and the second time may be determined by the second device itself, or may be pre-configured by the network side, or may be indicated by the first device to the second device.

[0573] the number of N first nodes expected by the second device;

[0574] M first node combinations expected by the second device, where M is a positive integer, and the first node combination includes at least one first node;

[0575] identifiers corresponding to the M first node combinations expected by the second device;

[0576] Among the candidate node combinations indicated by the first device, P first node combinations expected by the second device, where P is a positive integer;

[0577] Identifiers corresponding to P first node combinations expected by the second device among the candidate node combinations indicated by the first device;

[0581] In the candidate node ranking indicated by the first device, the identifiers corresponding to the T first node rankings expected by the second device.

[0582] In this embodiment, the "node combination" in the first node combination and candidate node combination refers to one or more first nodes, which can be grouped based on different parameters to form different node combinations. For example, if the first node is a TRP, the node combination can be expressed as a TRP pattern.

[0583] As an optional embodiment, the method further includes:

[0584] receiving information of the candidate node combinations sent by the first device, where each candidate node combination is composed of at least one first node in the first set;

[0585] The candidate node combination information includes at least one of the following:

[0586] One or more first nodes corresponding to each candidate node combination;

[0587] The identifier corresponding to each candidate node combination.

[0588] In this embodiment, the first device may send information about one or more candidate node combinations to the second device. Each candidate node combination includes one or more first nodes. The first set may include multiple candidate node combinations. For example: the first device is LMF, the first node is TRP, LMF indicates one or more TRP pattern information included in the first set, and a TRP pattern may include one or more TRPs in the first set; it may also include a TRP pattern identifier corresponding to each TRP pattern.

[0591] The candidate node ranking information includes at least one of the following:

[0592] One or more first nodes corresponding to each candidate node ranking;

[0594] In this embodiment, the first device may send information about one or more candidate node rankings to the second device. Each candidate node ranking includes rankings of one or more first nodes. The first set may include multiple candidate node rankings.

[0597] The sending the feedback information to the first device includes:

[0598] The feedback information is sent to the first device every B cycles, where B is a positive integer.

[0599] In this embodiment, the first device may instruct the first node in the first set to transmit and / or measure a reference signal every A cycles. The second device may send feedback information to the first device every B cycles. Preferably, B is equal to A. For example, the LMF instructs the TRP in the first set to transmit DL-PRS or measure UL-SRS-pos every A cycles, and the second device (one or more of the UE, gNB, and TRP) sends feedback information every A cycles.

[0600] In some embodiments, the method further comprises: determining input information of a model and / or function for positioning according to the channel-related information.

[0601] In this embodiment, after the first device receives the feedback information sent by the second device, it can determine, based on the feedback information, that the first node combination included in the second set is at least one of the node combinations included in the first set. For example, the LMF can determine, based on the feedback information, that the TRP pattern included in the second TRP set is at least one of the TRP patterns in the first TRP set.
