RedCap UEs suffer from reduced positioning accuracy in RRC_INACTIVE and RRC_IDLE states when performing frequency hopping measurements and reporting of positioning reference signals. In particular, it is difficult to combine PRS signals to improve bandwidth when not all hopping signals can be received.
By introducing measurement and failure reporting mechanisms, and by receiving frequency hopping threshold requests for successful and failed measurements, network devices can schedule frequency hopping operations to ensure that RedCap UEs receive all hopping signals, thereby improving positioning accuracy.
Through measurement and failure reporting mechanisms, the network can effectively schedule frequency hopping operations, improve the positioning accuracy and system performance of RedCap UEs, and enhance network capacity.

[0023] As used herein, the terms “resource,” “transmission resource,” “resource block,” “physical resource block” (PRB), “uplink resource,” or “downlink resource” can refer to any resource used to perform communication, such as communication between a terminal device and a network device, including resources in the time domain, frequency domain, spatial domain, code domain, or any other combination of time, frequency, spatial, and / or code domain resources used to enable communication. In the following, unless explicitly stated otherwise, resources in the frequency and time domains will be used as examples of transmission resources used to describe some exemplary embodiments of this disclosure. Note that the exemplary embodiments of this disclosure are equally applicable to other resources in other domains.
[0024] For downlink (DL) positioning reference signal (PRS) frequency hopping (FH) used for positioning of RedCap user equipment (UE), it is agreed that RedCap UEs support PRS reception (Rx) frequency hopping for Radio Resource Control Inactive (RRC_INACTIVE) and Radio Resource Control Idle (RRC_IDLE) states. However, PRS frequency hopping may not be used only for RedCap UEs; it may also apply to normal UEs.
[0025] When a RedCap UE is performing a location operation, the total PRS bandwidth (BW) is typically wider than the RedCap UE's BW. For example, as Figure 1A As shown, the RedCap UE can receive a hop 105 of a 20 MHz PRS transmission, and the five hops of this PRS transmission are transmitted consecutively. The RedCap UE can then combine the PRS received in the five hops. Furthermore, as... Figure 1B As shown, the RedCap UE receives the overlapping PRB 110 between two adjacent frequency hopping frequencies to measure the phase difference between the frequencies, as the phase difference may be unavoidable due to inherent equipment impairments. The maximum bandwidth supported by the RedCap UE is 20MHz for FR1 and 400MHz for FR2.
[0026] As stated above, regarding frequency hopping measurements and reporting, it is agreed that for DL Rx hopping or UL Tx hopping, the UE or gNB may report a single measurement based on multiple hops received for positioning using DL PRS or UL SRS. The UE or gNB may also report a single measurement associated with a single received hop. For DL PRS Rx hopping, a single instance of the measurement gap can be used for all frequency hopping received with DL PRS having an Rx hopping. However, the reported measurement may not be based on a single instance of the measurement gap. The UE is not forced to measure all frequency hopping, but may attempt to do so. Further investigation is needed regarding how many / which received hops are used in measurement reports.
[0027] When frequency hopping is used for PRS transmission in a RedCap UE, the RedCap UE needs to receive all frequency hops so that it can combine the received PRS signals. To maximize the benefits of frequency hopping, each hop needs to be transmitted on a different carrier / frequency. If the RedCap UE cannot receive the signal for a particular hop, combining all hops is impossible, thus reducing positioning accuracy. Therefore, it is difficult to perform RedCap positioning using frequency hopping when the RedCap UE fails to receive a signal in multiple hops. For Rx frequency hopping, there will be overlapping RBs (Resource Blocks) between different or adjacent hops. The UE receives PRS through multiple frequency hops and combines them into a wideband PRS. Based on the overlapping RBs, the UE estimates the phase difference between hops. When the UE combines multiple frequency hops into a wideband PRS, the UE uses the estimated phase difference between the frequency hops.
[0028] An example embodiment of this disclosure provides a measurement reporting scheme. Using this scheme, a first device (such as a UE) receives a first request for a measurement report from a second device (such as a location server), the measurement report being sent based on conditions related to a first frequency hopping threshold for a successful measurement of a reference signal. Alternatively or additionally, the first device receives a second request for a failure report, the failure report being sent based on conditions related to a second frequency hopping threshold for a failed measurement of the reference signal. Based on receiving at least one of the first and second requests, the first device sends at least one of the measurement report and the failure report.
[0029] In this way, the network can obtain information about successful and / or failed transmissions of the reference signal. The network can then take action. For example, if the initial transition fails to be delivered to the first device, frequency hopping can be stopped. The remaining frequency hopping transmissions can be rescheduled so that the first device can receive all transitions. Therefore, the transmission performance of the reference signal can be improved, and consequently, system performance and network capacity can be increased.
[0030] It should be noted that although this problem originates from the positioning of RedCap UEs, the solution proposed in this paper can be generally applied to any other use case and purpose. For example, the proposed solution can be applied to other devices, including terminal devices and network devices. Furthermore, the proposed solution can be applied to sounding reference signals (SRS) used for UL positioning and other reference signals for other purposes. Additionally, the proposed solution can be applied to sidelink positioning reference signals.
[0031] Figure 2 An example communication environment 200 in which example embodiments of the present disclosure may be implemented is shown.
[0032] The communication environment 200 includes a terminal device 210, such as a UE. In an NR positioning scenario, the terminal device 210 can operate as a RedCap UE. The communication environment 200 also includes a base station 220, such as a gNB, that can communicate with the terminal device 210. The base station 220 can serve one or more cells and / or manage one or more Transmit / Receive Points (TRPs), where one or more cells or TRPs can enable one or more beams.
[0033] like Figure 2 As shown, the communication environment 200 includes a location server 230, such as a location management function (LMF). The location server 230 can provide location-related services to the terminal device 210. The location server 230 can be implemented by a physical or virtual device. The location server 230 can be implemented as a hardware-based, firmware, and / or algorithm-based software component within any network node (such as a terminal device, base station, etc.).
[0034] In some exemplary embodiments, the link from base station 220 or location server 230 to terminal device 210 may be referred to as a downlink, and the link from terminal device 210 to base station 220 or location server 230 may be referred to as an uplink. In DL, base station 220 or location server 230 is a transmitting (TX) device (or transmitter), and terminal device 210 is a receiving (RX) device (or receiver). In UL, terminal device 210 is a TX device (or transmitter), and base station 220 or location server 230 is an RX device (or receiver).
[0035] Communication in communication environment 200 can be implemented according to any suitable communication protocol, including but not limited to cellular communication protocols such as first-generation (1G), second-generation (2G), third-generation (3G), fourth-generation (4G), fifth-generation (5G), and sixth-generation (6G), wireless local network communication protocols such as IEEE 802.11, and / or any other currently known or future-developed protocols. Furthermore, communication can utilize any suitable wireless communication technology, including but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiple Access (OFDM), Discrete Fourier Transform Extended OFDM (DFT-s-OFDM), and / or any other currently known or future-developed technologies.
[0036] It should be understood that, for the purpose of explanation, Figure 2 The number and type of devices are shown without implying any limitations. For example, location server 230 is shown as physically separate from base station 220 for illustration only. In some example embodiments, location server 230 may be co-located with base station 220, or physically integrated into or implemented as part of base station 220.
[0037] In the communication environment 200, the terminal device 210 can be configured with frequency hopping for a reference signal. In a positioning scenario, the reference signal can be a Positioning Reference Signal (PRS). For example, each hop with the PRS can be sent from the base station 220 to the terminal device 210. Multiple hops are sequentially used to transmit the PRS over a wide bandwidth (BW). The location server 230 can provide positioning assistance data to the terminal device 210 via the base station 220, which includes at least a configuration of frequency hopping for the DL PRS. In some embodiments, based on a request from the location server 230, the terminal device 210 can transmit a condition measurement report and / or a condition failure report to the location server 230.
[0038] In the following description, for illustrative purposes, some example embodiments are depicted in which terminal device 210 or UE sends a report to location server 230 or base station 220. However, in some example embodiments, the operations described with respect to the terminal device or UE can be implemented on the network side for UL positioning purposes. In this case, the operations described with respect to the network can be implemented at the terminal device.
[0039] Figure 3 A signaling diagram of an example measurement reporting process 300 between a first device 310 and a second device 320 according to some example embodiments of the present disclosure is shown. The first device 310 may operate as one of a terminal device and a base station or a location server, and the second device 320 may operate as the other of a terminal device and a base station or a location server. For purposes of discussion, the first device 310 will be referred to as... Figure 2 The terminal device 210 operates and the second device 320 acts as... Figure 2 Some embodiments are described in the case of operation of base station 220 or location server 230.
[0040] like Figure 3 As shown, the second device 320 can send (330) a first request for a conditional measurement report to the first device 310. The condition for the measurement report is based on a first frequency hopping threshold for a successful measurement of a reference signal. The reference signal may include the PRS in DL positioning. In some example embodiments, the first frequency hopping threshold may be the number of consecutive successful frequency hoppings, for example, X=3 [hops], where X represents any integer.
[0041] For example, in a DL positioning scenario where the second device 320 operates as an LMF 230 and the first device 310 operates as a terminal device 210, when the frequency hopping configuration for the DL PRS (as an example of a reference signal) is provided to the first device 310 as positioning assistance data, the second device 320 may request a report (also called a positioning measurement report) from the first device 310 regarding positioning measurements on a specific resource of the DL PRS only if the first device 310 successfully performs measurements from more than a predetermined number of consecutive frequency hoppings indicated by a first frequency hopping threshold. In other words, the first device 310 may send a positioning measurement report only if the number of successful measurements from consecutive DL PRS frequency hopping is greater than the configured threshold. In some example embodiments, the first frequency hopping threshold may be a percentage value of the number of successful frequency hoppings, such as Y% frequency hopping, where Y represents a positive number.
[0042] The first frequency hopping threshold can be configured by a second device 320 that can operate as a location server 230. In some example embodiments, a common value for the number of successful frequency hopping can be configured by the second device 320 (operating as a location server 230 for different base stations). In some other example embodiments, different values for the number of successful frequency hopping can be configured by the second device 320 (operating as a location server 230) for the respective base stations. For example, the first frequency hopping threshold can be configured by the second device 320 to have a common value or to have different values for each gNB / TRP.
[0043] In some example embodiments, the first frequency hopping threshold may include a common value for the number of successful frequency hoppings defined in the technical specification. For example, the first frequency hopping threshold may be a common value defined in the specification.
[0044] Alternatively or additionally, the first frequency hopping threshold may include a value of a threshold for the number of successful frequency hoppings set by the first device 310. In the example, if the first device 310 fails to obtain sufficient measurements, the first device 310 may report the suggested threshold value to the network (e.g., a location server or base station).
[0045] After receiving (335) the first request from the second device 320, the first device 310 sends (340) a measurement report to the second device 320. Accordingly, the second device 320 receives (345) the measurement report. In some example embodiments, the first device 310 may determine whether the value of a first number of frequency hopping corresponding to a successful measurement is equal to or greater than a first frequency hopping threshold. If the first device 310 determines that the value of the first number is equal to or greater than the first frequency hopping threshold, the first device 310 may send a measurement report based on a successful measurement.
[0046] In one example, in an embodiment where the first frequency hopping threshold includes the number of consecutive successful frequency hoppings, in a DL positioning scenario where the first device 310 operates as terminal device 210 and the reference signal is DL PRS, the first device 310 can perform DL PRS frequency hopping for a configured DL PRS resource. The first device 310 can report positioning measurements for a specific DL PRS resource configured for DL PRS frequency hopping from more than a threshold number of consecutive DL PRS frequency hoppings for each DL PRS resource. Positioning measurements may include, for example, Reference Signal Time Difference (RSTD) or UE Rx-Tx time difference.
[0047] For example, the first device 310 can be configured to send 18 PRS from 18 TRPs for DL PRS frequency hopping. Assume that positioning measurements require at least 4 out of 6 frequency hopping frequencies. If the first device 310 obtains 10 timing measurements from 10 TRPs based on more than 3 DL PRS frequency hopping frequencies, then the first device 310 will report these 10 timing measurements and discard the others. In this way, the second device 320 (e.g., location server 230) can filter out less accurate measurements to accurately estimate the location of the first device 310. Based on this feature, the first measurement filtering / selection process can be performed by the first device 310.
[0048] In some example embodiments, if the first device 310 determines that the value of the first number is less than the first frequency hopping threshold, the first device 310 may send one or more reference signal resource identifiers (IDs) associated with one or more failed frequency hopping, wherein the measurement failed on the one or more frequency hopping. The ID may include an ID identifying a resource of a reference signal or multiple IDs identifying the failed frequency hopping.
[0049] Alternatively or additionally, the first device 310 may send the number to indicate how many frequency hoppings were missed. In some example embodiments, the number may include the number of lost frequency hoppings that meet a first frequency hopping threshold. Alternatively, or as another alternative, the first device 310 may send a suggested first frequency hopping threshold for a successful measurement of the reference signal.
[0050] For example, in a DL positioning scenario where the first device 310 operates as terminal device 210 and the reference signal is DL PRS, the first device 310 can perform DL PRS reception using frequency hopping. If the first device 310 successfully performs a measurement, it can report the positioning measurement. Otherwise, if the first device 310 does not obtain a measurement that meets a first frequency hopping threshold—for example, if the first device 310 does not obtain a measurement based on the threshold number of DL PRS frequency hopping—it will not report the positioning measurement. Additionally, the first device 310 can report the DL PRS resource ID and how many DL PRS frequency hoppings it needs to receive to achieve the threshold number of hoppings for that DL PRS resource.
[0051] Therefore, the second device 320 can be rescheduled to transmit the reference signal. In some example embodiments, the second device 320 can transmit a configuration for the failed portion of the reference signal, where the failed portion corresponds to a failed frequency hopping. The second device 320 can then send the failed portion of the reference signal to the first device 310. For example, if the second device 320 operates as a location server 230, it can instruct the base station 220 to transmit the failed portion of the reference signal. If the second device 320 operates as a base station 220, it can send the failed portion of the reference signal to the first device 310. Alternatively or additionally, the second device 320 can transmit additional configuration for the reference signal. The reference signal can then be retransmitted.
[0052] In some example embodiments, the first device 310 may send an indication of whether the successful portion of the reference signal has been stored, where the successful portion of the reference signal has been successfully received by the first device. In the example, the rescheduling of the failed portion of the reference signal may depend on such an indication. For example, the first device 310 may indicate the ability to store and decode. If the first device 310 can store the normally received portion of the reference signal on the successful frequency hopping, then the first device 310 will indicate failed frequency hopping, and those failed frequency hoppings will be retransmitted. The first device 310 can then combine the signals from all the frequency hoppings. If the first device 310 is unlikely to store the normally received portion of the reference signal (e.g., due to the limited internal storage / buffer size of the first device 310), then the first device 310 will request the retransmission of all hops in future transmissions.
[0053] For example, a second device 320 (such as location server 230) can reschedule to transmit the failed portion of the reference signal. The second device 320 can indicate how to configure the next RS in one of the two options above: configure the failed portion of the reference signal, or reconfigure the reference signal. If the failed portion of the reference signal is configured, the first device 310 can (restart) receive the failed portion. This option can be enabled if the first device 310 is indicating that the successfully received portion of the RS corresponding to the successful frequency hopping is stored. The first device 310 can also (restart) receive retransmitted RSs.
[0054] Alternatively or additionally, the second device 320 may send (330) a second request to the first device 310 for a conditional failure report. The condition for the failure report is based on a second frequency hopping threshold for failed measurements of the reference signal. For example, if the first device 310 detects a certain number of failures in measuring frequency hopping, the second device 320 may request the first device 310 to send a failure report (or report reception failure). In some example embodiments, the first device 310 may be configured with conditions for determining RS FH failure.
[0055] The second frequency hopping threshold may include the number of consecutive failed frequency hoppings. Alternatively or additionally, the second frequency hopping threshold may include at least one of the following: a percentage value of the number of failed frequency hoppings, a threshold value of the number of failed frequency hoppings configured by the location server, a threshold value of the number of failed frequency hoppings defined in the technical specification, or a threshold value of the number of failed frequency hoppings set by the first device.
[0056] After receiving the second request (335) from the second device 320, the first device 310 sends a failure report to the second device 320. In some example embodiments, the first device 310 may stop receiving reference signals.
[0057] In some example embodiments, the first device 310 may determine whether the value of a second frequency hopping number corresponding to a failed measurement is equal to or greater than a second frequency hopping threshold. If it is determined that the value of the second number is equal to or greater than the second frequency hopping threshold, the first device 310 may send a failure report. The features associated with the first frequency hopping threshold also apply to the second frequency hopping threshold. For simplicity, details will be omitted.
[0058] In some example embodiments, measurements fail on a second number of frequency hopping events. In one example, the first device 310 may determine the expected failure of measurements on the second number of frequency hopping events based on conflicts between reference signal resources used for a reference signal and resources used for other signals or channels.
[0059] For example, the first device 310 can determine whether any conflict may occur between the reference signal resource and the synchronization signal block (SSB) resource based on the current scheduling information received from the base station 220 and / or the information provided regarding the SSB locations, including the serving cell and neighboring cells. Based on this determination / observation, the first device 310 makes a further decision regarding whether future reception of the reference signal with FH is successfully measured (i.e., the number of hops successfully measured is greater than the second frequency hopping threshold). If failure is expected, the first device 310 determines and reports a reception failure to the network. Therefore, the first device 310 can stop receiving the reference signal. For example, the first device 310 can calculate the number of frequency hopping steps for the receivable reference signal. Based on this calculation, the first device 310 will declare a reception failure.
[0060] For a specific cell, the first device 310 may be aware of a conflict between the reference signal resource and the SSB resource. If so, the first device 310 can report the failure to the second device 320 (which can be either the base station 220 or the location server 230), causing the base station 220 to cancel the reference signal transmission. If the second device 320 operates as the location server 230, it can notify the base station 220 of the report from the first device 310. The base station 220 then cancels the reference signal transmission. By doing so, the base station 220 can schedule other DL data, physical downlink shared channels, and physical downlink control channels instead of the reference signal.
[0061] In some example embodiments, there are cases where another signal or channel that conflicts with the reference signal has a higher priority than the reference signal. For example, for a serving cell, both data transmission and the reference signal can be scheduled simultaneously. Then, the first device 310 cannot receive both and needs to select one. As another example, when a neighboring cell transmits a reference signal, the neighboring cell can transmit both the SSB and RS simultaneously. Then, the first device 310 also needs to select which signal to receive. This selection can be based on its priority, which can be predefined or configured by the network. For example, the SSB can have a higher priority than the reference signal. As a result, the first device 310 can send a failure report regarding the reference signal to the second device 320.
[0062] In some example embodiments, the number of consecutive failure frequency hoppings can be the first Z frequency hoppings, where Z represents any integer. In this way, the first device 310 can initially indicate that FH can be stopped due to reception failure.
[0063] Failure reports can be sent by the first device 310 in Radio Resource Control (RRC) signaling. For example, the first device 310 can use RRC signaling to send a failure indication. Alternatively or additionally, failure reports can be sent in physical control channels such as the Physical Uplink Control Channel (PUCCH) and / or physical shared channels such as the Physical Uplink Shared Channel (PUSCH).
[0064] Alternatively or additionally, failure reports can be sent in resources indicated by the second device 320. For example, if the first device 310 is not configured with resources for reporting, the network can additionally indicate resources for reporting by the first device 310. As another example, failure reports can be sent in transmitted data. For example, the first device 310 in an RRC connection can use a payload to attach failure reports to outgoing data (or data transmission).
[0065] In some example embodiments, the first device 310 may indicate whether to store the received RS. The first device 310 may then resume receiving the failed portion or the net set of reference signals. The features and operations associated with the first device 310 in the failure case, as described above, also apply to failure reporting scenarios. Details will be omitted for simplicity.
[0066] Figure 4 An example failure reporting process according to some example embodiments of the present disclosure is illustrated. In this example, the first device 310 operates as the terminal device 210, and the reference signal is PRS.
[0067] like Figure 4 As shown, the first device 310 can determine that a conflict between the PRS transmission and other DL transmissions occurs at times 402, 404, and 406. The first device 310 can then report the failure of the DL PRS FH before the PRS transmission begins.
[0068] The following will refer to Figure 5A and 5B A detailed description of the example measurement reporting process is provided. In these examples, UE 502 serves as... Figure 3 The first device 310 is operated as an example implementation, and the LMF 504 is operated as an example implementation of the second device 320. The reference signal is DL PRS.
[0069] In such Figure 5A In the illustrated process 508, at 510, LMF 504 may send positioning assistance data including DL PRS configuration for PRS FH. At 512, LMF 504 may configure conditions, including the number of measurement thresholds that may depend on a first or second frequency hopping threshold. At 514, LMF 504 may request a positioning measurement report for a specific PRS resource (e.g., a first request, indicated by request "A"). At 516, LMF 504 may request a report regarding reception failure (e.g., a second request, indicated by request "B"). At 518, UE 502 may send an indication of its capabilities in storage and decoding.
[0070] In response to the second request, at 520, UE 502 can calculate the number of potential reception failures for the DL PRS transition. At 522, UE 502 can determine whether to declare a failure based on configured conditions. At 524, UE 502 can report the failure to LMF 504. At 526, LMF 504 can send an indication to gNB 506 regarding the failed UE report. At 528, gNB 506 can choose not to transmit the PRS with FH. At 530, gNB 506 can schedule and transmit additional DL data.
[0071] In response to the first request, at 532, gNB 506 can send a PRS to UE 502 on each hop. At 534, if the measurement requirements are not met, UE 502 can determine not to report. At 536, UE 502 can report the DL PRS resource ID and the required number of DL PRS hops to LMF 504 to ensure the threshold is met. At 538, LMF 504 can indicate whether to restart receiving the failed portion or receive a new set of PRS. At 540, LMF 504 can reschedule to send the PRS.
[0072] Figure 5B The process in 550 is similar to Figure 5A The process is as follows: 500. The only difference is that at 552, the failure report is sent by UE 502 to both gNB 506 and LMF 504. Therefore, LMF 504 does not need to instruct gNB 506 to report the failure.
