Description

[0002] For Artificial Intelligence (AI) positioning, User Equipment (UE), Transmission-Reception Point (TRP), and Next-Generation NodeB (gNB) determine channel measurements using measurement reference signals (Positioning Reference Signals (PRS) / Sounding Reference Signals-pos). AI / ML models take these channel measurements as input, and their output can be user location or intermediate positioning data (such as Time of Arrival (ToA), line-of-sight (LoS) / non-line-of-sight (NLoS) indicators, etc.). Model inputs typically satisfy specific statistical characteristics and exhibit a certain mapping relationship with user location / intermediate positioning data. Through sufficient data collection and supervised learning, AI / ML models can learn this pattern, thereby enhancing positioning accuracy. However, the data collection for model training depends on the configuration of the positioning reference signals, and the availability of flexible and diverse positioning reference signal configurations cannot guarantee the performance of AI / ML models.

[0034] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0035] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] To facilitate understanding of the solution proposed in this application, the relevant content will be introduced first.

[0038] Regarding AI positioning, five cases have been reached to further study the potential technical solutions and protocol impacts of AI positioning.

[0039] In Case 3a, the model is deployed on the gNB / TRP side, and the channel measurement entity is also the gNB / TRP. The gNB / TRP determines the model input by measuring the SRS-pos signals transmitted by UEs in its own cell and neighboring cells, and starts model training after collecting sufficient training data. During data collection, the gNB / TRP needs to receive the neighboring cell SRS-pos configuration sent by the Location Management Function (LMF) to obtain the time-frequency location of the neighboring cell SRS-pos signals it needs to measure. The SRS-pos configuration determines the measurement location of the gNB / TRP, thus affecting the AI / ML model input. That is, the SRS-pos configuration is closely related to the performance of the AI / ML model.

[0040] In existing technologies, each gNB / TRP can only decide on the SRS-pos configuration of its own cell, and the measurement preferences of neighboring cells (such as the configuration corresponding to the SRS-pos signal of this cell that the neighboring cell expects to measure) are not considered when making this decision. The drawback is that when a neighboring cell deploys an AI / ML model and wants to measure the SRS-pos signal of this cell as model input, the SRS-pos configuration of this cell may not be the most preferred by the neighboring cell, thus affecting the measurement results and the AI / ML model input, and consequently affecting the performance of the AI / ML model.

[0041] For Case 3b, the model is deployed on the LMF side, and the channel measurement entity is the gNB / TRP. The gNB / TRP measures the SRS-pos signals transmitted by UEs in its own cell and neighboring cells, and then sends the channel measurements to the LMF. The LMF determines the model input, and starts model training after collecting sufficient training data. In Case 3b, the model is trained on the LMF side, so the LMF has model-related information (such as the SRS-pos configuration of each gNB / TRP during model data collection). In this case, having the LMF specify the SRS-pos configuration of each gNB / TRP ensures the consistency of the AI / ML model training and inference phases on the LMF side, thereby ensuring the performance of the AI / ML model. Existing technology supports the LMF requesting SRS-pos transmission features from the gNB / TRP. The gNB / TRP refers to the features requested by the LMF to determine the SRS-pos configuration of its own cell and feeds it back to the LMF.

[0042] For example, see Figure 1 The LMF can send a POSITIONING INFORMATION REQUEST to the gNB / TRP. This request may contain SRS-pos transmission characteristics preferred by the LMF. Specifically, the SRS-pos transmission characteristics that the LMF can request include: the number of SRS-pos resource sets, the number of SRS-pos resources in each resource set, and the period of each SRS-pos resource. Upon receiving the POSITIONING INFORMATION REESPONSE from the LMF, if the request contains the requested SRS-pos transmission characteristics, the gNB / TRP can refer to the LMF's request to determine the SRS-pos configuration for its cell. Subsequently, it sends a POSITIONING INFORMATION RESPONSE to the LMF, which includes the cell's SRS-pos configuration.

[0043] See afterward. Figure 2After receiving the location information feedback, the LMF can send a POSITIONING ACTIVATION REQUEST to the gNB / TRP. The activation request contains the SRS-pos configuration that the LMF wants to activate. If the gNB / TRP accepts the request, it will activate the corresponding SRS-pos transmission.

[0044] See Figure 3 The LMF can also send a MEASUREMENT REQUEST to each gNB / TRP. The MEASUREMENT REQUEST includes the SRS-pos configuration of the cell / neighbor cell. If the gNB / TRP accepts the request, it will start the measurement at the corresponding time and frequency location.

[0045] It should be noted that while existing technologies support the LMF requesting preferred SRS-pos transmission features from the gNB / TRP, the SRS-pos transmission features that the LMF can request are relatively limited. The LMF can only request: the number of SRS-pos resource sets, the number of SRS-pos resources contained in each resource set, and the period of each SRS-pos resource. On the gNB / TRP side, there may be multiple candidate SRS-pos configurations that satisfy the features requested by the LMF, but the final configuration may not be the one most preferred by the LMF, which will also affect the performance of the AI / ML model.

[0046] To address the aforementioned technical problems, embodiments of this application provide information transmission methods, apparatuses, devices, and media. The methods and apparatuses are based on the same concept. Since the methods and apparatuses solve problems in similar ways, their implementations can be mutually referenced, and repeated details will not be elaborated upon.

[0047] like Figure 4 The diagram shown is a flowchart illustrating an information transmission method provided in an embodiment of this application. This method is applied to a first wireless access device, meaning it is executed by the first wireless access device, which may be a gNB / TRP. Specifically, the method includes:

[0048] Step 401: Send a first request to the first core network device, the first request including the identifier and / or parameter set of the first positioning reference signal configuration.

[0049] Optionally, the first core network device is a core network device used for location management, such as an LMF network element.

[0050] The identifier and / or parameter set of the first positioning reference signal configuration refers to the identifier and / or parameter set of the positioning reference signal configuration preferred or preferred for measurement by the first wireless access device. It should be noted that the first core network device, by receiving the first request sent by the first wireless access device, can ascertain which one or more positioning reference signal configurations the first wireless access device prefers or prefers to measure (as can be determined through the identifier of the positioning reference signal configuration), and / or can ascertain the conditions that the preferred or preferred positioning reference signal configuration of the first wireless access device must meet (as can be determined through the parameter set of the positioning reference signal configuration).

[0051] Optionally, the first positioning reference signal is configured as the positioning reference signal configuration of a neighboring cell. It should be understood that the positioning reference signal configuration of a neighboring cell refers to the positioning reference signal configuration of a neighboring cell that the first wireless access device prefers or tends to measure.

[0052] Optionally, the set of parameters configured for the first positioning reference signal includes one or more of the following:

[0053] Period, the period being used to indicate the period of the positioning reference signal resource;

[0054] Offset, the offset being used to indicate the starting position of the positioning reference signal resource;

[0055] Symbol count, which indicates the total number of symbols occupied by a single positioning reference signal resource;

[0056] Frequency offset, which is used to indicate the location of the starting resource block of the positioning reference signal resource;

[0057] Comb configuration, wherein the comb configuration is used to indicate the comb mapping method of the positioning reference signal resources;

[0058] Frequency hopping configuration, wherein the frequency hopping configuration is used to indicate the frequency domain position of the location reference signal resource under frequency hopping conditions;

[0059] Spatial information, which is used to indicate the transmission beam associated with the positioning reference signal resource.

[0060] It should be noted that the positioning reference signal involved in the embodiments of this application is SRS, and / or SRS-pos, and the set of parameters configured for the positioning reference signal includes the transmission characteristics of the positioning reference signal.

[0061] The solution corresponding to step 401 is applicable to the scenario where the AI / ML model is deployed on the first wireless access device side. The first wireless access device, acting as both a channel measurement entity and a network deployment entity, requests the identifier and / or parameter set of the first positioning reference signal configuration from the first core network device. This helps the first core network device to more clearly understand the positioning reference signal configurations of neighboring cells that it prefers to measure. Subsequently, the first core network device can negotiate with the wireless access devices corresponding to the neighboring cells. The neighboring cells can refer to the request from the first wireless access device to determine their own positioning reference signal configuration, enabling the first wireless access device to measure its preferred positioning reference signal resources to determine channel measurements. The obtained channel measurements can be used to determine the AI / ML model input, thereby maximizing the performance of the AI / ML model.

[0062] Alternatively, in step 402, a second request is received from the first core network device, the second request including a set of parameters configured for the second positioning reference signal.

[0063] Optionally, the second positioning reference signal is configured as the positioning reference signal configuration for this cell. It should be understood that the positioning reference signal configuration for this cell refers to the positioning reference signal configuration of this cell (the cell provided by the first radio access device) that the first core network device prefers or tends to use.

[0064] Optionally, the set of parameters configured for the second positioning reference signal includes one or more of the following:

[0065] Period, the period being used to indicate the period of the positioning reference signal resource;

[0066] Offset, the offset being used to indicate the starting position of the positioning reference signal resource;

[0067] Symbol count, which indicates the total number of symbols occupied by a single positioning reference signal resource;

[0068] Frequency offset, which is used to indicate the location of the starting resource block of the positioning reference signal resource;

[0069] Comb configuration, wherein the comb configuration is used to indicate the comb mapping method of the positioning reference signal resources;

[0070] Frequency hopping configuration, wherein the frequency hopping configuration is used to indicate the frequency domain position of the location reference signal resource under frequency hopping conditions;

[0071] Spatial information.

[0072] The parameter set for the second positioning reference signal configuration refers to the parameter set of the positioning reference signal configuration (for this cell) preferred or tended to be used by the first core network device (such as an LMF network element). It should be noted that the first wireless access device can learn the conditions that the positioning reference signal configuration (for this cell) preferred or tended to be used by the first core network device must meet by receiving a second request sent by the first core network device. Furthermore, the first core network device can provide more detailed transmission characteristics of the positioning reference signal (i.e., the specific content included in the parameter set of the second positioning reference signal configuration). This helps the first wireless access device to more clearly understand the positioning reference signal configuration preferred by the first core network device, thereby ensuring that the final positioning reference signal configuration helps maximize the performance of the AI / ML model.

[0073] The solution corresponding to step 402 is applicable to situations where the AI / ML model is deployed on the first core network device or the first wireless access device side.

[0074] When the AI / ML model is deployed on the first core network device side, that is, the first core network device acts as a network deployment entity, it requests the first radio access device for the set of parameters of the (cell-specific) positioning reference signal configuration preferred or tended to be used by the first core network device. This set of parameters provides more detailed transmission characteristics of the positioning reference signal, which helps the first radio access device to understand the positioning reference signal configuration preferred by the first core network device more clearly, thereby ensuring that the final positioning reference signal configuration helps to maximize the performance of the AI / ML model.

[0075] When the AI / ML model is deployed on the first wireless access device side, the first core network device can request the first wireless access device a set of parameters for the (cell-specific) positioning reference signal configuration that the first core network device prefers or tends to use. This set of parameters provides more detailed transmission characteristics of the positioning reference signal, which helps the first wireless access device to understand the positioning reference signal configuration preferred by the first core network device more clearly.

[0076] As an optional implementation, before sending the first request to the first core network device in step 401, the method of this application further includes:

[0077] The system receives at least one positioning reference signal configuration information sent by the first core network device, wherein each positioning reference signal configuration information includes an identifier of a positioning reference signal configuration and a positioning reference signal configuration.

[0078] That is, receiving a set of positioning reference signal configuration information sent by the first core network device, including M positioning reference signal configurations and corresponding configuration identifiers. M is an integer greater than or equal to 1.

[0079] It should be noted that at least one positioning reference signal configuration information is generated by the first core network device based on the positioning reference signal configuration reported by other wireless access devices.

[0080] The identifier for the positioning reference signal configuration is used to identify the positioning reference signal configuration, such as positioning reference signal configuration 1 and positioning reference signal configuration 2.

[0081] Each of the positioning reference signal configuration information includes an identifier of a positioning reference signal configuration and a positioning reference signal configuration, which can be understood as: each of the positioning reference signal configuration information includes a positioning reference signal configuration and an identifier of the positioning reference signal configuration.

[0082] Optionally, each positioning reference signal configuration corresponds to one or more positioning reference signal resources (identified by the ID of the positioning reference signal resource), one or more positioning reference signal resource sets (identified by the ID of the positioning reference signal resource set), or an uplink positioning reference signal configuration on a wireless access device.

[0083] One of the uplink positioning reference signal configurations on a wireless access device can be a positioning reference signal configuration on a gNB / TRP UL BWP, and / or a gNB / TRP UL Active BWP.

[0084] Furthermore, the method in this embodiment of the invention further includes:

[0085] Based on the received at least one positioning reference signal configuration information, the identifier of the first positioning reference signal configuration is determined, wherein the identifier of the first positioning reference signal configuration includes the identifier of at least one positioning reference signal configuration among the at least one positioning reference signal configuration information.

[0086] As described above, each positioning reference signal configuration information includes an identifier for a positioning reference signal configuration and a positioning reference signal configuration. If there are M positioning reference signal configuration information items, then there are M identifiers for positioning reference signal configurations and M positioning reference signal configurations.

[0087] In this step, the first wireless access device selects one or more identifiers of positioning reference signal configurations from at least one positioning reference signal configuration information as the identifier of the first positioning reference signal configuration. That is, the identifier of the first positioning reference signal configuration includes the identifiers of at least one positioning reference signal configuration from at least one positioning reference signal configuration information. It can also be understood that the first wireless access device may have one or more preferred or preferred positioning reference signal configurations for measurement.

[0088] Optionally, each of the positioning reference signal configurations corresponds to one or more positioning reference signal resources, one or more sets of positioning reference signal resources, or a wireless access device uplink positioning reference signal configuration.

[0089] Here, if each of the positioning reference signal configurations corresponds to a positioning reference signal resource, then a positioning reference signal configuration includes at least one of the following: an identifier of the positioning reference signal configuration, positioning reference signal frequency information, and positioning reference signal resource information.

[0090] The positioning reference signal frequency information includes at least one of the following: point A location, sub-carrier space (SCS), starting resource block (RB) location, and bandwidth (BW).

[0091] A positioning reference signal resource includes at least one of the following: resource ID, period, offset, starting symbol position, number of symbols, frequency offset, comb configuration, frequency hopping configuration, and spatial information. Specifically, the period indicates the period of the positioning reference signal resource; the offset indicates the starting position of the positioning reference signal resource; the starting symbol position indicates which symbol in the transmission time slot the positioning reference signal resource should begin transmission in; the number of symbols indicates the total number of symbols occupied by a single positioning reference signal resource; the frequency offset indicates the starting RB position of the positioning reference signal resource; the comb configuration indicates the comb mapping method of the positioning reference signal resource, including the comb value and offset; and the frequency hopping configuration indicates the frequency domain position of the positioning reference signal resource under frequency hopping conditions.

[0092] If each of the positioning reference signal configurations corresponds to a positioning reference signal resource set, then a positioning reference signal configuration includes at least one of the following: an identifier of the positioning reference signal configuration, positioning reference signal frequency information, and a positioning reference signal resource set information.

[0093] The information regarding the frequency of the positioning reference signal is described in the section above and will not be repeated here.

[0094] A single positioning reference signal resource set includes at least one of the following: resource set ID, resource IDs contained within the set, and resource type. The resource type indicates whether the positioning reference signal resources in the positioning reference signal resource set are periodic, semi-periodic, or aperiodic.

[0095] The contents of a positioning reference signal resource information, and a detailed explanation of those contents, are described in the sections above and will not be repeated here.

[0096] If each of the positioning reference signal configurations corresponds to an uplink positioning reference signal configuration on a wireless access device, then a positioning reference signal configuration includes at least one of the following: an identifier of the positioning reference signal configuration, positioning reference signal frequency information, one or more positioning reference signal resource set information, and one or more positioning reference signal resource information.

[0097] The information regarding the positioning reference signal frequency includes the details described above and will not be repeated here.

[0098] The contents of a single positioning reference signal resource set are described in the above sections and will not be repeated here.

[0099] The contents of a positioning reference signal resource information, and a detailed explanation of those contents, are described in the sections above and will not be repeated here.

[0100] As an optional implementation, the method of this application also includes:

[0101] Receive a measurement request message sent by the first core network device, wherein the measurement request message includes one or more of the following:

[0102] Configuration of positioning reference signals from the second wireless access device;

[0103] The identifier configured for the first positioning reference signal;

[0104] At least one positioning reference signal configuration information;

[0105] Measure the start and end times.

[0106] This implementation involves the first core network device sending a first request to the first wireless access device. The first core network device then determines the preferred neighboring cell positioning reference signal configuration based on the identifier and / or parameter set of the first positioning reference signal configuration, and / or determines to update the neighboring cell positioning reference signal configuration based on the preferred neighboring cell positioning reference signal configuration. After the first core network device negotiates and confirms with the neighboring cell, the measurement phase begins.

[0107] When the model is deployed on the first wireless access device side, as an optional implementation method for later model training, the method of this application also includes:

[0108] The system receives the truth label and / or label type corresponding to the channel measurement quantity sent by the first core network device. The channel measurement quantity is determined by the first wireless access device by measuring the positioning reference signal corresponding to the first positioning reference signal.

[0109] Here, the label type can be ToA or Los / NLoS indicators.

[0110] During the model training phase, the model needs to be optimized by analyzing the error between the predicted value output by the model and the true value corresponding to the ground truth label, so as to obtain a stable model.

[0111] As an optional implementation, the method of this application also includes:

[0112] The first wireless access device reports capability information to the first core network device, wherein the capability information indicates that the first wireless access device supports the identifier of requesting the configuration of the first positioning reference signal, and / or supports the set of parameters for requesting the configuration of the first positioning reference signal.

[0113] When the first wireless access device participates in data collection for model training on the other wireless access devices' side, it can report the local cell's positioning reference signal configuration to the first core network device. This information is used by the first core network device to generate positioning reference signal configuration information, which then allows other wireless access devices to select their preferred positioning reference signal configuration, thereby ensuring that the final positioning reference signal configuration helps maximize AI / ML model performance. As an optional implementation, the method of this invention further includes:

[0114] Receive a third request message sent by the first core network device, the third request message being used to request the first radio access device to configure the uplink positioning reference signal;

[0115] Send to the first core network device the positioning reference signal configuration on the uplink active bandwidth of the first radio access device, or the positioning reference signal configuration on at least a portion of other uplink bandwidths of the first radio access device, excluding the uplink active bandwidth; or...

[0116] According to the first indication information carried in the third request message, the first core network device is sent the uplink positioning reference signal configuration of the first wireless access device; wherein, the first indication information is used to indicate whether the first wireless access device reports the positioning reference signal configuration on other uplink bandwidths of the first wireless access device, excluding the uplink active bandwidth.

[0117] This implementation provides three methods for the first wireless access device to report the location reference signal configuration: First, the first wireless access device only reports the location reference signal configuration on the first wireless access device's uplink active bandwidth (such as UL Active BWP); Second, the first wireless access device reports the location reference signal configuration on at least some other uplink bandwidths (such as other UL BWPs besides UL Active BWP) in addition to the uplink active bandwidth; Third, the first wireless access device decides whether to report the location reference signal configuration on other uplink bandwidths (such as other UL BWPs besides UL Active BWP) based on the instruction of the first core network device, i.e., the first instruction information in the third request message.

[0118] For example, the first indication information is a 1-bit indication bit, used to indicate whether the first wireless access device reports the positioning reference signal configuration on other uplink bandwidths besides the uplink active bandwidth. Wherein, the indication bit is 0, indicating that the first wireless access device only reports the positioning reference signal configuration on the uplink active bandwidth of the first wireless access device; the indication bit is 1, indicating that the first wireless access device reports the positioning reference signal configuration on other uplink bandwidths besides the uplink active bandwidth.

[0119] The information transmission method in this application embodiment, by sending a first request to a first core network device, the first request including the identifier and / or parameter set of a first positioning reference signal configuration, helps the first core network device to more clearly understand the positioning reference signal configuration of neighboring cells preferred by the first radio access device, thereby ensuring that the positioning reference signal configuration of neighboring cells helps to maximize the performance of the AI / ML model on the first radio access device side; or, receiving a second request sent by the first core network device, the second request including the parameter set of a second positioning reference signal configuration, which helps the first radio access device to more clearly understand the positioning reference signal configuration preferred by the first core network device, thereby ensuring that the positioning reference signal configuration of the current cell helps to maximize the performance of the AI / ML model.

[0120] like Figure 5 The diagram shown is a flowchart illustrating an information transmission method provided in an embodiment of this application. This method is applied to a first core network device, meaning it is executed by the first core network device, which can be an LMF network element. Specifically, the method includes:

[0121] Step 501: Receive a first request sent by a first wireless access device, the first request including an identifier and / or a set of parameters of a first positioning reference signal configuration;

[0122] It should be noted that this embodiment is a method embodiment corresponding to the first wireless access device, i.e., the first core network device side. For a detailed understanding and explanation of related terms or steps, please refer to the description of the method on the first wireless access device side; it will not be repeated here.

[0123] Optionally, the first positioning reference signal is configured as the positioning reference signal configuration of a neighboring cell. It should be understood that the positioning reference signal configuration of a neighboring cell refers to the positioning reference signal configuration of a neighboring cell that the first wireless access device prefers or tends to measure.

[0124] Optionally, the set of parameters configured for the first positioning reference signal includes one or more of the following:

[0125] Period, the period being used to indicate the period of the positioning reference signal resource;

[0128] Frequency offset, which is used to indicate the location of the starting resource block of the positioning reference signal resource;

[0129] Comb configuration, wherein the comb configuration is used to indicate the comb mapping method of the positioning reference signal resources;

[0130] Frequency hopping configuration, wherein the frequency hopping configuration is used to indicate the frequency domain position of the location reference signal resource under frequency hopping conditions;

[0131] Spatial information, which is used to indicate the transmission beam associated with the positioning reference signal resource.

[0132] Here, by receiving a first request from a first radio access device, the first core network device can learn which one or more positioning reference signal configurations the first radio access device prefers or tends to measure (identified by the identifier of the positioning reference signal configuration), and / or, what conditions the preferred or preferred positioning reference signal configuration must meet (identified by the parameter set of the positioning reference signal configuration). This helps the first core network device to more clearly understand the positioning reference signal configurations of neighboring cells preferred by the first radio access device. Subsequently, the first core network device can negotiate with the radio access devices corresponding to the neighboring cells. The neighboring cells can refer to the request from the first radio access device to determine the positioning reference signal resource configuration of the neighboring cells, enabling the first radio access device to measure its preferred positioning reference signal resources to determine channel measurements. The obtained channel measurements can be used to determine the input of the AI / ML model, thereby maximizing the performance of the AI / ML model.

[0133] Alternatively, in step 502, a second request is sent to the first wireless access device, the second request including a set of parameters for the second positioning reference signal configuration.

[0134] Optionally, the second positioning reference signal is configured as the positioning reference signal configuration for this cell. It should be understood that the positioning reference signal configuration for this cell refers to the positioning reference signal configuration of this cell (the cell provided by the first radio access device) that the first core network device prefers or tends to use.

[0135] Optionally, the set of parameters configured for the second positioning reference signal includes one or more of the following:

[0136] Period, the period being used to indicate the period of the positioning reference signal resource;

[0137] Offset, the offset being used to indicate the starting position of the positioning reference signal resource;

[0138] Symbol count, which indicates the total number of symbols occupied by a single positioning reference signal resource;

[0139] Frequency offset, which is used to indicate the location of the starting resource block of the positioning reference signal resource;

[0140] Comb configuration, wherein the comb configuration is used to indicate the comb mapping method of the positioning reference signal resources;

[0141] Frequency hopping configuration, wherein the frequency hopping configuration is used to indicate the frequency domain position of the location reference signal resource under frequency hopping conditions;

[0142] Spatial information.

[0143] It should be noted that by sending a second request to the first radio access device, the first core network device can enable the first radio access device to know the conditions under which the (cell-specific) location reference signal configuration preferred or favored by the first core network device meets. Furthermore, the first core network device can provide more detailed transmission characteristics of the location reference signal (i.e., the specific content included in the parameter set of the second location reference signal configuration). This helps the first radio access device to more clearly understand the location reference signal configuration preferred by the first core network device, thereby ensuring that the final location reference signal configuration helps maximize the performance of the AI / ML model.

[0144] As an optional implementation, before receiving the first request sent by the first wireless access device in step 501, the method of this application further includes:

[0145] Obtain at least one positioning reference signal configuration information;

[0146] At least one of the positioning reference signal configuration information is sent to the first wireless access device, each of the positioning reference signal configuration information including an identifier of a positioning reference signal configuration and a positioning reference signal configuration.

[0147] Optionally, each of the positioning reference signal configurations corresponds to one or more positioning reference signal resources, one or more sets of positioning reference signal resources, or a wireless access device uplink positioning reference signal configuration.

[0148] Here, the positioning reference signal configuration of the second wireless access device (i.e., any wireless access device other than the first wireless access device) can be reported to the first core network device, so that the first core network device can obtain at least one positioning reference signal configuration information. The specific implementation is described below.

[0149] As an optional implementation, obtaining at least one of the positioning reference signal configuration information includes:

[0150] Send a fourth request message to the second wireless access device, the fourth request message being used to request the second wireless access device to configure the uplink positioning reference signal;

[0151] Here, the second wireless access device refers to any wireless access device other than the first wireless access device.

[0152] Receive the uplink positioning reference signal of the second wireless access device sent by the second wireless access device and configure it;

[0153] Based on the received uplink positioning reference signal configuration from the second wireless access device, at least one of the positioning reference signal configuration information is generated.

[0154] As an optional implementation, receiving the uplink positioning reference signal configuration of the second wireless access device sent by the second wireless access device includes:

[0155] Receive the positioning reference signal configuration on the uplink activation bandwidth of the second wireless access device sent by the second wireless access device; or,

[0156] The second wireless access device receives a positioning reference signal configuration sent by the second wireless access device, which includes at least a portion of the other uplink bandwidths besides the uplink activation bandwidth.

[0157] This implementation presents two methods for the second wireless access device to report the location reference signal configuration. First, the second wireless access device only reports the location reference signal configuration on its uplink active bandwidth (such as the UL Active BWP). Second, the second wireless access device reports the location reference signal configuration on at least a portion of other uplink bandwidths (such as other UL BWPs besides the UL Active BWP), in addition to the uplink active bandwidth.

[0158] Optionally, the fourth request message includes second indication information, which is used to indicate whether the second wireless access device reports the positioning reference signal configuration on other uplink bandwidths of the second wireless access device, excluding the uplink active bandwidth.

[0159] Here, the second wireless access device, based on the instruction from the first core network device, namely the second instruction information in the fourth request message, decides whether to report the positioning reference signal configuration on other uplink bandwidths (such as other UL BWPs besides UL Active BWP).

[0160] For example, the second indication information is a 1-bit indication bit, used to indicate whether the second wireless access device reports the positioning reference signal configuration on other uplink bandwidths besides the uplink active bandwidth. Specifically, if the indication bit is 0, it indicates that the second wireless access device only reports the positioning reference signal configuration on the uplink active bandwidth; if the indication bit is 1, it indicates that the second wireless access device reports the positioning reference signal configuration on other uplink bandwidths besides the uplink active bandwidth.

[0161] As an optional implementation, the method of this application also includes:

[0162] After receiving the first request sent by the first wireless access device, the system determines the first positioning reference signal configuration based on the identifier and / or parameter set of the first positioning reference signal configuration included in the first request, and / or determines whether to update the parameter set of the current positioning reference signal configuration based on the first positioning reference signal configuration.

[0163] Furthermore, as an optional implementation, the method of this application also includes:

[0164] If a set of parameters for updating the current positioning reference signal configuration is determined, a fifth request message is sent to the second wireless access device, the fifth request message including the identifier and / or parameter set of the first positioning reference signal configuration;

[0165] The system receives a first response message from a second wireless access device. This first response message is sent when the second wireless access device determines that it can update its uplink positioning reference signal configuration according to the content of the fifth request message. The first response message includes confirmation information, an identifier and / or a set of parameters for the first positioning reference signal configuration, and / or the uplink positioning reference signal configuration of the second wireless access device; or...

[0166] The second response message is received from the second wireless access device when the second wireless access device determines that it cannot update the uplink positioning reference signal configuration of the second wireless access device according to the content of the second request message. The second response message includes rejection information and / or the reason for rejection.

[0167] It should be noted that after receiving the first request sent by the first wireless access device, the first core network device can determine which one or more neighboring cells the first wireless access device tends to measure based on the identifier and / or parameter set of the first positioning reference signal configuration included in the first request. (If the first request includes the identifier of the first positioning reference signal configuration, the cell ID can be determined based on the corresponding resource configuration or resource set configuration of the corresponding reference signal configuration. Alternatively, if the first request includes the parameter set of the first positioning reference signal configuration, the first core network device can determine which one or more wireless access devices' positioning reference signal configurations satisfy the first request based on the uplink positioning reference signal configuration of the second wireless access device sent by the second wireless access device. These wireless access devices that satisfy the request can all be considered as cells that the first wireless access device tends to measure.) After the first core network device determines the parameter set for updating the neighboring cell positioning reference signal configuration of the first radio access device according to the first positioning reference signal configuration, the first core network device needs to negotiate with the neighboring cells (i.e., the second radio access devices, which can be one or more) that the first radio access device tends to measure, requesting these radio access devices to transmit positioning reference signals according to the first positioning reference signal configuration. The specific negotiation process is implemented in the above manner. If a first response message is received from the second radio access device, it indicates successful negotiation, and the second radio access device will transmit positioning reference signals according to the first positioning reference signal configuration. If a second response message is received from the second radio access device, it indicates negotiation failure. Furthermore, after receiving the first response message from the second radio access device, the method of this application further includes:

[0168] Send a measurement request message to the first wireless access device and / or the second wireless access device, the measurement request message including one or more of the following:

[0169] Configuration of positioning reference signals from the second wireless access device;

[0170] At least one positioning reference signal configuration information;

[0171] The identifier configured for the first positioning reference signal;

[0172] Measure the start and end times.

[0173] Here, upon receiving the first response message from the second wireless access device, it indicates that the negotiation was successful. The second wireless access device will transmit the positioning reference signal according to the configuration of the first positioning reference signal. After that, it can enter the measurement phase, that is, the first core network device sends a measurement request message to the first wireless access device and / or the second wireless access device and subsequent steps.

[0174] When the model is deployed on the first wireless access device side, as an optional implementation method for later model training, the method of this application also includes:

[0175] Send a truth label and / or label type corresponding to the channel measurement quantity to the first wireless access device, wherein the channel measurement quantity is determined by the first wireless access device by measuring the positioning reference signal corresponding to the first positioning reference signal.

[0176] During the model training phase, the model needs to be optimized by analyzing the error between the predicted value output by the model and the true value corresponding to the ground truth label, so as to obtain a stable model.

[0177] As an optional implementation, the method of this application also includes:

[0178] The first wireless access device receives capability information reported by the first wireless access device, wherein the capability information indicates that the first wireless access device supports an identifier for requesting a first positioning reference signal configuration and / or a set of parameters for requesting a first positioning reference signal configuration.

[0179] The information transmission method in this application embodiment receives a first request sent by a first wireless receiving device. The first request includes an identifier and / or parameter set of a first positioning reference signal configuration. This helps the first core network device to more clearly understand the positioning reference signal configuration of the neighboring cells preferred by the first wireless access device, thereby ensuring that the final positioning reference signal configuration helps to maximize the performance of the AI / ML model on the first wireless access device side. Alternatively, a second request is sent to the first wireless access device. The second request includes a parameter set of a second positioning reference signal configuration. This helps the first wireless access device to more clearly understand the positioning reference signal configuration of the local cell preferred by the first core network device, thereby ensuring that the final positioning reference signal configuration helps to maximize the performance of the AI / ML model.

[0180] The following examples illustrate the implementation process of the information transmission method of this application from the perspective of inter-device interaction.

[0181] Example 1: For Case 3a, the model is deployed on the gNB side, and the gNB requests the identifier of the first positioning reference signal configuration.

[0182] Step 11: The first gNB / TRP sends a positioning reference signal request message to the LMF;

[0183] The location reference signal request information includes an identifier corresponding to the location reference signal configuration preferred by the first gNB / TRP. It should be understood that the location reference signal configuration preferred by the first gNB / TRP refers to the location reference signal configuration of the neighboring cells preferred by the first gNB / TRP.

[0184] Step 12: The LMF determines the positioning reference signal configuration based on the positioning reference signal request information, and / or determines whether to update the positioning reference signal transmission characteristics.

[0186] The granularity of each positioning reference signal configuration information can be selected in several ways, possibly including the following:

[0194] The period is used to indicate the period of the positioning reference signal resources.

[0219] Send a positioning reference signal configuration request message to the second gNB / TRP, the positioning reference signal configuration request message including the determined positioning reference signal configuration and / or the updated positioning reference signal transmission characteristics;

[0220] The second gNB / TRP should be understood as any gNB / TRP other than the first gNB / TRP.

[0221] If the second gNB / TRP determines that it can configure the UE to send a positioning reference signal according to the positioning reference signal configuration and / or the updated positioning reference signal transmission characteristics (which can also be understood as updating the positioning reference signal configuration on the uplink bandwidth of the second gNB / TRP according to the positioning reference signal configuration and / or the updated positioning reference signal transmission characteristics), then the second gNB / TRP sends a positioning reference signal configuration response message to the LMF. The response message includes confirmation information, and / or the positioning reference signal configuration, and / or the identifier corresponding to the positioning reference signal configuration.

[0222] If the second gNB / TRP cannot configure the UE to send a positioning reference signal according to the positioning reference signal configuration and / or the updated positioning reference signal transmission characteristics, then the second gNB / TRP sends a positioning reference signal configuration response message to the LMF, which includes rejection information and / or the reason for rejection.

[0223] Optionally, if the second gNB / TRP determines that the UE can send a positioning reference signal according to the positioning reference signal configuration and / or the updated positioning reference signal transmission characteristics, after the LMF receives the corresponding positioning reference signal configuration response message, it may further include: sending measurement request information to the third gNB / TRP, the measurement request information including the positioning reference signal configuration sent by the second gNB / TRP, and / or, the identifier corresponding to the positioning reference signal configuration, and / or, the positioning reference signal configuration information, and / or, the measurement start and end time.

[0225] Optionally, before the LMF generates the positioning reference signal configuration information, the method in this embodiment further includes:

[0226] Send a positioning reference signal configuration request to the second gNB / TRP.

[0227] After receiving the positioning reference signal configuration request information, the second gNB / TRP reports the positioning reference signal configuration of its cell to the LMF. Specifically, the methods by which the second gNB / TRP reports the positioning reference signal configuration include the following:

[0244] Option 3: The second gNB / TRP, based on LMF indication, decides whether to report the positioning reference signal configuration on other UL BWPs besides the UL Active BWP.

[0245] The LMF's Location Reference Signal Configuration Request message to the second gNB / TRP includes a 1-bit indicator bit to indicate whether the second gNB / TRP should report the location reference signal configuration on UL BWPs other than the UL Active BWP. When the indicator bit is 0, the second gNB / TRP is instructed to report only the location reference signal configuration on the UL Active BWP, in which case the second gNB / TRP uses the first method described above. When the indicator bit is 1, the second gNB / TRP is instructed to report the location reference signal configuration on some / all UL BWPs other than the UL Active BWP, in which case the second gNB / TRP uses the second method described above.
