[0104] In some embodiments, positioning can be enhanced based on AI technology to enhance positioning accuracy through AI models trained with large amounts of data.
[0105] In some embodiments, the positioning use case may include two sub-use cases: direct AI / ML positioning and AI / ML assisted positioning.
[0106] In some embodiments, depending on the entity where the AI model resides and the entity performing the (positioning) calculation, it can be divided into five sub-scenarios as shown in Figures 2A to 2E. Please refer to Figures 2A to 2E, which are schematic diagrams of AI positioning sub-scenarios according to embodiments of the present disclosure.
[0107] The sub-scenario shown in Figure 2A can also be described as Case 1, or "Case 1: UE-based positioning with UE-side model, direct AI / ML or AI / ML assisted positioning." In Figure 2A, the AI model is deployed on the UE side, and the UE performs positioning calculations, supporting direct AI / ML positioning or AI / ML assisted positioning. In some embodiments, the gNB can send a positioning reference signal (PRS) to the UE. Furthermore, the UE can perform PRS measurements and input the collected data (including but not limited to PRS measurement results) into the AI model for inference, obtaining a positioning result output by the AI model. Furthermore, the UE can send the positioning result (such as the location shown in Figure 2A) to the LMF.
[0108] Among them, the sub-scenario shown in Figure 2B can also be described as Case 2a, or "Case 2a: UE-assisted / LMF-based positioning with UE-side model, AI / ML assisted positioning". In Figure 2B, the AI model is deployed on the UE side, and the LMF side performs positioning calculations, supporting AI / ML assisted positioning. In some embodiments, the gNB can send PRS to the UE; further, the UE can perform PRS measurement and input the collected data (including but not limited to PRS measurement results) into the AI model for inference to obtain intermediate results output by the AI model; further, the UE can send the intermediate results (such as the intermediate results shown in Figure 2B) to the LMF, so that the LMF can perform positioning calculations based on the intermediate results.
[0109] The sub-scenario shown in Figure 2C can also be described as Case 2b, or "Case 2b: UE-assisted / LMF-based positioning with LMF-side model, direct AI / ML positioning." In Figure 2C, the AI model is deployed on the LMF side, which performs positioning calculations and supports direct AI / ML positioning. In some embodiments, the gNB can send a PRS to the UE; further, the UE can perform PRS measurements and send PRS-based measurement results (such as the PRS-based measurement shown in Figure 2C) to the LMF; further, the LMF can input the collected data (including but not limited to the PRS-based measurement results) into the AI model for inference, thereby obtaining the positioning results output by the AI model.
[0110] Among them, the sub-scenario shown in Figure 2D can also be described as Case 3a, or "Case 3a: NG-RAN node assisted positioning with gNB-side model, AI / ML assisted positioning". In Figure 2D, the AI model is deployed on the gNB side, and the LMF side performs positioning calculations, supporting AI / ML-assisted positioning. In some embodiments, the UE can send a channel sounding reference signal (SRS) to the gNB; the gNB can perform SRS measurement and input the collected data (including but not limited to SRS measurement results) into the AI model for inference to obtain intermediate results output by the AI model; further, the gNB can send the intermediate results (such as the intermediate results shown in Figure 2D) to the LMF, so that the LMF can perform positioning calculations based on the intermediate results.
[0111] The sub-scenario shown in Figure 2E can also be described as Case 3b, or "Case 3b: NG-RAN node assisted positioning with LMF-side model, direct AI / ML positioning." In Figure 2E , the AI model is deployed on the LMF side, and the LMF performs positioning calculations, supporting direct AI / ML positioning. In some embodiments, the UE can send an SRS to the gNB; the gNB can perform SRS measurements and send SRS-based measurement results to the LMF (such as the SRS-based measurement shown in Figure 2E ); further, the LMF can input the collected data (including but not limited to the SRS measurement results) into the AI model for inference, thereby obtaining the positioning results output by the AI model.
[0112] In some embodiments, for the case where the AI model is deployed on the UE side, such as the sub-scenarios shown in Figures 2A and 2B, a transmission point (transmission / reception point, TRP) can send PRS to multiple UEs based on the same PRS configuration, and a UE may receive PRS sent by multiple TRPs, where each TRP can be based on the same or different PRS configuration; in this case, since the PRSs sent by multiple TRPs on the same time-frequency resources may interfere with each other, the PRS configured on the network side may not meet the quality requirements of the AI model on the UE side.
[0113] For example, FIG3A is a schematic diagram showing PRS interference in the time domain according to an embodiment of the present disclosure. As shown in FIG3A , time is represented horizontally, increasing from left to right, each large rectangle represents a PRS resource set, and each small rectangle in the large rectangle represents a PRS resource included in the PRS resource set. Assuming that TRP#1 sends PRS to UE#1 on PRS resource #1 and PRS resource #5, and TRP#2 sends PRS to UE#1 on PRS resource #1 and PRS resource #2, the PRSs sent by TRP#1 and TRP#2 on the same time domain resource (that is, the time domain resource corresponding to PRS resource #1) may interfere with each other, resulting in the data collected by UE#1 failing to meet the quality requirements of the AI model for training data.
[0114] For example, FIG3B is a schematic diagram illustrating PRS interference in the frequency domain according to an embodiment of the present disclosure. As shown in FIG3B , in a time slot, PRS resource #1 and PRS resource #2 are two adjacent PRS resources; wherein PRS resource #1 includes SL PRS resource #0 and SL PRS resource #1 using different comb offsets, and PRS resource #2 includes SL PRS resource #2 and SL PRS resource #3 using different comb offsets. In this case, interference may exist between adjacent SL PRS resource #0 and SL PRS resource #1, interference may exist between adjacent SL PRS resource #2 and SL PRS resource #3, and even interference may exist between SL PRS resource #0 and SL PRS resource #2.
[0115] FIG4 is a schematic diagram illustrating an interaction method of a positioning reference signal muting request and configuration method according to an embodiment of the present disclosure.
[0116] As shown in FIG4 , the method for requesting and configuring positioning reference signal muting includes:
[0117] Step S401: The terminal sends a first request signaling to a network device.
[0118] In some embodiments, an AI model is deployed on the terminal. The AI model can be used for direct AI positioning and / or AI-assisted positioning. For example, the terminal can be a UE as shown in Figure 2A, or the terminal can be a UE as shown in Figure 2B. For the AI-based positioning process, please refer to the embodiments related to Figures 2A and 2B above, which will not be repeated here.
[0119] In some embodiments, the network device may include a core network device. In some embodiments, the core network device may include a LMF.
[0120] In some embodiments, the first request signaling is used to request the first TRP to perform PRS muting processing.
[0121] In some embodiments, the terminal may receive PRSs sent by multiple TRPs, and the first TRP may include one or more TRPs among the multiple TRPs.
[0122] In some embodiments, the first TRP may include a TRP in which the PRS sent to the terminal does not meet the quality requirements of the AI model. And / or, the first TRP may include a TRP in which the PRS sent by the first TRP interferes with the PRS sent by the second TRP, resulting in the PRS sent by the second TRP to the terminal not meeting the quality requirements of the AI model.
[0123] It should be noted that in the embodiments of the relevant technology, the PRS silence configuration is usually determined by the network side, which may result in the PRS configured on the network side not meeting the quality requirements of the AI model on the UE side. In the above embodiment of the present disclosure, the terminal sends a first request signaling to the network device through the terminal, and the terminal can request the first TRP to perform PRS silence processing. Accordingly, in the case where the AI model is deployed on the UE side, the terminal can actively request the network device to perform PRS silence processing on the first TRP, which is conducive to the terminal triggering the PRS silence configuration on demand and reducing the interference between the PRSs sent by multiple TRPs, thereby meeting the quality requirements of the AI model for data (including but not limited to the original data collected by the terminal, the training data in the training phase, the input data in the reasoning phase, etc.), thereby improving the positioning accuracy.
[0124] In some embodiments, the first request signaling is used to indicate that the terminal expects the first TRP not to send a PRS, that is, the terminal sending the first request signaling expects the first TRP not to send a PRS to the terminal and not to send a PRS to other terminals. And / or, the first request signaling is used to indicate that the terminal expects the first TRP not to send a PRS to the terminal. And / or, the first request signaling is used to indicate that the terminal expects the first TRP to stop sending a PRS to the terminal.
[0125] It should be noted that in the above embodiment, "stop sending PRS" may mean that the network device has already started sending PRS to the terminal, and the terminal requests the network device to stop sending PRS. "not sending PRS" may mean that the network device has not yet started sending PRS to the terminal, and the terminal requests the network device not to send PRS, or it may mean that the network device has already started sending PRS to the terminal, and the terminal requests the network device to stop sending PRS.
[0126] In the above embodiment, the first request signaling may include the TRP identifier of the first TRP. For example, the first request signaling may include the TRP ID of the first TRP. In some possible implementations, the dl-PRS-ID IE in the first request signaling may represent the TRP identifier. For the specific implementation of the dl-PRS-ID IE, please refer to the embodiment related to step 501 below, which will not be described in detail here.
[0127] In some embodiments, the first request signaling is used to indicate that the terminal desires the first TRP not to send the first PRS resource set. That is, the terminal sending the first request signaling desires the first TRP not to send the first PRS resource set to the terminal itself and not to send the first PRS resource set to other terminals. And / or, the first request signaling is used to indicate that the terminal desires the first TRP not to send PRS to the terminal on the first PRS resource set. And / or, the first request signaling is used to indicate that the terminal desires the first TRP to stop sending PRS to the terminal on the first PRS resource set.
[0128] In the above embodiment, the first request signaling may include the resource set identifier of the first PRS resource set, or the TRP identifier of the first TRP and the resource set identifier of the first PRS resource set. For example, the first request signaling may include the resource set ID of the first PRS resource set. In some possible implementations, the NR-DL-PRS-ResourceSet IE in the first request signaling may represent the resource set identifier. For the specific implementation of the NR-DL-PRS-ResourceSet IE, please refer to the embodiment related to step 501 below, which will not be described in detail here.
[0129] It should be noted that, in the above embodiment, when the first request signaling is used to indicate that the terminal expects the first TRP not to send PRS or the first PRS resource set, the network device may not reconfigure the first PRS configuration information and not send PRS or the first PRS resource set, or the network device may first reconfigure the first PRS configuration information and then not send PRS or the first PRS resource set according to the reconfigured first PRS configuration information.
[0130] In some embodiments, the first request signaling is used to indicate that the terminal expects the first TRP to reconfigure the first PRS configuration information according to the PRS muting requirement. The first PRS configuration information is used for data collection in the AI model training phase.
[0131] In the above embodiment, the first request signaling may include a TRP identifier, a resource set identifier, and / or a PRS muting pattern. The PRS muting pattern is used to indicate the PRS muting requirement of the terminal. For example, the first request signaling may include the TRP ID of the first TRP and the PRS muting pattern desired by the terminal.
[0132] In some embodiments, the PRS muting mode includes a first mode and / or a second mode. The first mode is used to indicate whether a PRS muting period includes multiple consecutive PRS transmission periods, and whether muting is performed on the PRS resource sets within each PRS transmission period during each PRS muting period. The second mode is used to indicate whether a PRS muting period includes one PRS transmission period, and whether muting is performed on repeated instances in the PRS resource sets during each PRS muting period. For the specific implementation of the first mode, please refer to the embodiment related to FIG. 6A below, and for the specific implementation of the second mode, please refer to the embodiment related to FIG. 6B below, which will not be described in detail here.
[0133] In some possible implementations, the DL-PRS-MutingOption1 IE in the first request signaling may indicate that the PRS muting mode expected by the terminal is the first mode, and the NR-MutingPattern IE in the first request signaling may indicate the specific content of the first mode. In other possible implementations, the DL-PRS-MutingOption2 IE in the first request signaling may indicate that the PRS muting mode expected by the terminal is the second mode, and the NR-MutingPattern IE in the first request signaling may indicate the specific content of the second mode. For the specific implementation of the DL-PRS-MutingOption1 IE, the DL-PRS-MutingOption2 IE, and the NR-MutingPattern IE, please refer to the embodiment related to step 501 below, which will not be described in detail here.
[0134] In some embodiments, in addition to the PRS muting mode, the PRS muting requirement may also include at least one of the following: a frequency range of the PRS, such as FR1, FR2, etc.; a PRS resource allocation bandwidth, such as the number of PRBs; a PRS resource period; a PRS resource set period; the number of repeated transmissions of the PRS resource; the number of PRS symbols; the comb density of the PRS; and spatial domain information of the PRS, such as quasi-co-location (QCL) information.
[0135] In some embodiments, the first PRS configuration information and the legacy PRS configuration information may be independent of each other. In this case, the first request signaling may be effective only for the first PRS configuration information. The legacy PRS configuration information refers to the PRS configuration information known to those skilled in the art before the introduction of the AI model for positioning enhancement, and is not described in detail here.
[0136] In other embodiments, the first PRS configuration information and the legacy PRS configuration information are not independent of each other, that is, the legacy PRS configuration information may be used as the first PRS configuration information, or the legacy PRS configuration information may be adjusted to obtain the first PRS configuration information.
[0137] In some embodiments, the terminal may send the first request signaling to the network device before data collection in the AI model training phase. And / or, the terminal may send the first request signaling to the network device after data collection in the AI model training phase begins.
[0138] In some embodiments, the terminal may send a first request signaling to the network device based on prior information before collecting data in the AI model training phase. The prior information may include information obtained in the previous AI model training phase. For example, during the previous model training process, it was found that the PRS received by the terminal from TRP#1 did not meet the quality requirements of the AI model, and TRP#1 and TRP#2 interfered with each other. Therefore, before collecting data in this AI model training phase, a first request signaling may be sent to the network device. The first request signaling is used to request the network device to reconfigure the first PRS configuration information of TRP#1 and TRP#2, or the first request signaling is used to request the network device not to send PRS to the terminal on TRP#1 and TRP#2.
[0139] In some embodiments, after the data collection of the AI model training phase begins, the terminal may send a first request signaling to the network device in response to the received PRS not meeting the quality requirements of the AI model. If the signal-to-noise ratio (SNR) corresponding to the PRS received by the terminal is less than the first threshold, it can be determined that the received PRS does not meet the quality requirements of the AI model. And / or, if the signal-to-interference-plus-noise ratio (SINR) corresponding to the PRS received by the terminal is less than the second threshold, it can be determined that the received PRS does not meet the quality requirements of the AI model. Regarding the specific values of the first threshold and the second threshold, the present disclosure does not limit this.
[0140] In some embodiments, the terminal sends a first request signaling to the network device in response to the PRS received in any PRS transmission period not meeting the quality requirements of the AI model. Alternatively, the terminal sends a first request signaling to the network device in response to the number of PRS transmission periods in which the PRS received in any PRS silent period does not meet the quality requirements of the AI model exceeding a third threshold. The third threshold is greater than 0 and less than the number of PRS transmission periods included in a PRS silent period. The specific value of the third threshold is not limited in this disclosure.
[0141] In some embodiments, the PRS may include a PRS sent on one PRS resource; or, the PRS includes a PRS sent on one PRS resource set; or, the PRS includes a PRS sent on one TRP.
[0142] In some embodiments, the terminal sends a first request signaling to the network device in response to a PRS received on a PRS resource not meeting the quality requirements of the AI model. And / or, the terminal sends a first request signaling to the network device in response to a PRS received on a PRS resource set not meeting the quality requirements of the AI model. The terminal sends a first request signaling to the network device in response to a PRS received on a TRP not meeting the quality requirements of the AI model.
[0143] In some embodiments, the first request signaling is used to indicate that the terminal does not expect to receive the PRS sent by the first TRP after the first duration. The first duration may at least include the sum of the transmission duration of the terminal sending the first request signaling to the network device and the transmission duration of the network device sending the PRS to the terminal.
[0144] In some embodiments, the first request signaling is used to indicate that the terminal does not expect to receive the first PRS resource set sent by the first TRP after the second duration. The second duration may at least include the sum of the transmission duration of the terminal sending the first request signaling to the network device and the transmission duration of the network device sending the first PRS resource set to the terminal.
[0145] In some embodiments, the first request signaling is used to indicate that the terminal expects to receive a PRS sent by the first TRP according to the reconfigured first PRS configuration information after a third duration. The third duration may at least include the sum of a transmission duration for the terminal to send the first request signaling to the network device and a transmission duration for the network device to send the PRS to the terminal.
[0146] In some embodiments, the first PRS configuration information is used for data collection during the AI model training phase, and the second PRS configuration information is used during the AI model inference phase. If the terminal sends a first request signaling to the network device, and the network device reconfigures the first PRS configuration information, the terminal expects the second PRS configuration information to be consistent with the reconfigured first PRS configuration information.
[0147] In the above embodiments, the terminal can actively request the network device to reconfigure the first PRS configuration information during the training phase of the AI model, so that the PRS sent by the network device to the terminal according to the reconfigured first PRS configuration information can meet the data quality requirements of the AI model and improve the training effect of the AI model; and the terminal expects that in the inference phase of the AI model, the network device can send PRS to the terminal according to the second PRS configuration information consistent with the reconfigured first PRS configuration information, so that the input data in the inference phase of the AI model can also meet the data quality requirements of the AI model, thereby improving the positioning accuracy.
[0148] In some embodiments, the network device may receive first request signaling.
[0149] Step S402: The network device performs PRS silencing processing on the first TRP.
[0150] In some embodiments, the network device may perform PRS muting processing on the first TRP according to the PRS muting requirements of the terminal.
[0151] In one possible implementation, the first request signaling is used to instruct the first TRP not to send a PRS to the terminal, and the network device may not send a PRS to the terminal on the first TRP. And / or, the first request signaling is used to instruct the first TRP not to send a PRS to the terminal on the first PRS resource set, and the network device may cause the first TRP to not send a PRS to the terminal on the first PRS resource set. And / or, the first request signaling is used to instruct the first TRP to reconfigure the first PRS configuration information according to the PRS muting requirement, and the network device may cause the first PRS configuration information to be reconfigured according to the PRS muting requirement. The PRS muting mode included in the first request signaling is a first mode, and the network device reconfigures the first PRS configuration information according to the first mode. Alternatively, the PRS muting mode included in the first request signaling is a second mode, and the network device reconfigures the first PRS configuration information according to the second mode.
[0152] In the above embodiment, by sending a first request signaling to the network device by the terminal, the terminal can request to perform PRS silencing processing on the first TRP according to the PRS silencing requirement of the terminal. Accordingly, in the case where the AI model is deployed on the UE side, the terminal can actively request the network device to perform PRS silencing processing on the first TRP, which is conducive to the terminal triggering PRS silencing configuration on demand, reducing interference between PRSs sent by multiple TRPs, thereby meeting the AI model's data quality requirements and improving positioning accuracy.
[0153] In other embodiments, the network device may not perform PRS muting processing on the first TRP according to the PRS muting requirement of the terminal. In one possible implementation, the network device may not perform PRS muting processing on the first TRP, or the network device may independently determine new first PRS muting configuration information, and the new first PRS muting configuration information may fully or partially meet the PRS muting requirement.
[0154] In the above embodiment, since a TRP may send PRS to multiple UEs based on the same PRS configuration, when the TRP receives the first request signaling sent by some of the UEs, the TRP can comprehensively consider the overall network conditions and determine whether the current PRS configuration needs to be adjusted, instead of adjusting the PRS configuration in response to the first request signaling sent by any UE. This is beneficial to improving the overall performance and stability of the network and avoiding unnecessary signaling overhead, that is, avoiding the network equipment from frequently reconfiguring the PRS configuration and notifying the terminal of the new PRS configuration.
[0155] In some embodiments, the network device may send the PRS to the terminal according to the reconfigured first PRS configuration information.
[0156] In some embodiments, the network device may send the PRS to the terminal according to the second PRS configuration information. In some possible implementations, the second PRS configuration information is consistent with the reconfigured first PRS configuration information.
[0157] The communication method involved in the embodiment of the present disclosure may include at least one of steps S401 to 402. For example, step S401 may be implemented as an independent embodiment, and step S402 may be implemented as an independent embodiment.
[0158] In some embodiments, steps S401 and S402 may be performed in an interchangeable order or simultaneously.
[0159] In some embodiments, step S401 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
[0160] In some embodiments, step S402 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
[0161] In some embodiments, reference may be made to other optional embodiments described before or after the description corresponding to FIG. 4 .
[0162] First, embodiments of the present disclosure provide a method for requesting positioning reference signal muting. Figure 5 is a schematic flow chart illustrating a method for requesting positioning reference signal muting according to an embodiment of the present disclosure. The method for requesting positioning reference signal muting illustrated in this embodiment can be executed by a terminal.
[0163] As shown in FIG5 , the method for requesting positioning reference signal muting may include the following steps:
[0164] In step S501, a first request signaling is sent to a network device, where the first request signaling is used to request a first TRP to perform PRS silencing processing.
[0165] For example, UE#1 may send a first request signaling to the LMF, where the first request signaling is used to request TRP#1 to perform PRS silencing processing.
[0166] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0167] Optionally, the network device may receive a first request signaling sent by the terminal. In a further implementation, the network device may perform PRS muting processing on the first TRP according to the PRS muting requirement of the terminal; or may not perform PRS muting processing on the first TRP according to the PRS muting requirement of the terminal.
[0168] According to an embodiment of the present disclosure, the terminal sends a first request signaling to the network device through the terminal, and the terminal can request the first TRP to perform PRS silencing processing. Accordingly, in the case where the AI model is deployed on the UE side, the terminal can actively request the network device to perform PRS silencing processing on the first TRP, which is beneficial for the terminal to trigger the PRS silencing configuration on demand, reduce the interference between the PRSs sent by multiple TRPs, thereby meeting the AI model's quality requirements for data (including but not limited to the original data collected by the terminal, training data in the training phase, input data in the inference phase, etc.), and thus improve positioning accuracy.
[0169] In some embodiments, the first request signaling is used to indicate at least one of the following: the terminal expects the first TRP not to send PRS to the terminal; the terminal expects the first TRP not to send PRS to the terminal on the first PRS resource set; the terminal expects the first TRP to reconfigure the first PRS configuration information according to the PRS silence requirement, and the first PRS configuration information is used for data collection in the artificial intelligence AI model training phase, and the AI model is deployed on the terminal.
[0170] In some embodiments, the first request signaling includes at least one of the following: a TRP identifier, the TRP identifier is used to identify the first TRP; a resource set identifier, the resource set identifier is used to identify the first PRS resource set; a PRS muting mode, the PRS muting mode is used to indicate a PRS muting requirement.
[0171] In some embodiments, the PRS silent mode includes a first mode and / or a second mode; wherein the first mode is used to indicate whether one PRS silent period includes multiple consecutive PRS transmission periods, and whether silent processing is performed on the PRS resource set in each PRS transmission period in each PRS silent period; and the second mode is used to indicate whether one PRS silent period includes one PRS transmission period, and whether silent processing is performed on the repeated instances in the PRS resource set in each PRS silent period.
[0172] In some possible implementations, the dl-PRS-ID IE in the first request signaling may indicate a TRP identifier. The NR-DL-PRS-ResourceSet IE in the first request signaling may indicate a resource set identifier. The DL-PRS-MutingOption1 IE in the first request signaling may indicate that the terminal's desired PRS muting mode is the first mode. The DL-PRS-MutingOption2 IE in the first request signaling may indicate that the terminal's desired PRS muting mode is the second mode. The NR-MutingPattern IE in the first request signaling may indicate the specific content of the first mode or the second mode.
[0173] For example, the IE information that may be included in the first request signaling is as follows:
[0174] In some possible implementations, the first mode may be a mode of muting based on a DL PRS resource set. In the IE information of the above example, the dl-prs-MutingBitRepetitionFactor in the DL-PRS-MutingOption1 IE may indicate the number of PRS transmission periods included in a PRS muting period, and the NR-MutingPattern is a bitmap in which each bit indicates whether each PRS transmission period in the dl-prs-MutingBitRepetitionFactor PRS transmission periods is muted.
[0175] For example, FIG6A is a schematic diagram illustrating a method for performing PRS muting based on a first mode according to an embodiment of the present disclosure. As shown in FIG6A , the dl-prs-MutingBitRepetitionFactor is 4, meaning that a PRS muting period includes four consecutive PRS transmission periods. The NR-MutingPattern may include four bits, wherein the second bit indicates that the corresponding PRS transmission period is muted, and wherein the first, third, and fourth bits indicate that the corresponding PRS transmission period is not muted. That is, the first mode shown in FIG6A indicates that, in every four PRS transmission periods, muting is performed on the DL PRS resource set within the second PRS transmission period (indicated by a small rectangle with an unfilled gray background color).
[0176] In some possible implementations, the second mode may be a muting mode based on repeated instances in a DL PRS resource set. In the above example IE information, NR-MutingPattern is a bitmap, in which each bit indicates whether repeated instances of all resources in a PRS transmission period are muted.
[0177] For example, FIG6B is a schematic diagram illustrating a second pattern for performing PRS muting according to an embodiment of the present disclosure. As shown in FIG6B , a PRS resource set may include four PRS resources and repeated instances of each PRS resource (repeated instances are shown with the same pattern). In this case, the NR-MutingPattern may include eight bits, wherein the third and fifth bits indicate that the corresponding PRS transmission period is muted, and wherein the first, second, fourth, sixth, seventh, and eighth bits indicate that the corresponding PRS transmission period is not muted. That is, the second pattern shown in FIG6B indicates that, within the PRS resource set transmitted within each PRS transmission period, muting is performed on PRS resource #3 and PRS resource #5 (shown by small rectangles with an unfilled gray background color), while muting is not performed on the other resources in each PRS resource set (shown by small rectangles with a filled gray background color).
[0178] In some embodiments, sending a first request signaling to a network device includes: sending a first request signaling to the network device before data collection in an AI model training phase.
[0179] In some embodiments, sending the first request signaling to the network device includes: sending the first request signaling to the network device based on a priori information.
