Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure. It should be noted that, unless otherwise specified, the embodiments of this disclosure and the features in the embodiments can be combined with each other.

[0023] For ease of understanding, the terminology used in the embodiments of this disclosure will be introduced first.

[0024] 1. Non-terrestrial Network (NTN)

[0025] NTN is a key technology introduced in 5G, providing wireless resources through network devices such as satellites or drones instead of terrestrial base stations. Based on the different ways the satellite processes the signal, it can be divided into transparent transmission mode and regeneration mode. Transparent transmission mode: The NTN ground station sends the network device's signal to the satellite. The satellite converts the signal to its own frequency band before transmitting it to the terminal. Aside from frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, acting like a repeater. Regeneration mode: After the NTN ground station sends the gNB signal to the satellite, the satellite first demodulates and decodes the signal before re-encoding and modulating it (this process is regeneration), and then transmits the regenerated signal through its own frequency band.

[0026] Table 1 below shows the satellite altitude, orbit, and coverage area of ​​a typical NTN network:

[0027] Table 1

[0028]

[0029] 2. Synchronization Signal / Physical Broadcast Channel Block Measurement Timing Configuration (SMTC)

[0030] The NTN system introduces Connected-State Propagation Delay Difference (PDD) reporting and SMTC adjustment, which together optimize NTN mobility management and synchronization performance. PDD reporting refers to the terminal measuring the propagation delay difference between different satellites or base stations in connected mode and reporting this data to the network. The terminal obtains real-time delay difference data by measuring the propagation delay difference between the serving cell and neighboring cells. After this data is reported to the network, the network can make dynamic resource allocation and handover decisions based on this information to ensure communication continuity and stability. SMTC is the timing configuration for Synchronization Signal Block (SSB) measurement, which determines when the terminal performs SSB measurement. In the NTN system, the transmission time of SSB may change dynamically due to satellite movement. Therefore, the SMTC configuration needs to be adjusted to ensure that the UE can perform measurements within the correct time window, maintaining synchronization and network connectivity.

[0031] The data reported by PDD provides crucial decision-making support for SMTC adjustments. The network can dynamically adjust the SMTC configuration based on real-time latency difference data to optimize terminal measurement performance and synchronization accuracy.

[0032] 3. Conditional Handover (CHO)

[0033] Handover Request (CHO) is a condition-based autonomous handover mechanism that allows a terminal to proactively trigger a handover process when specific conditions are met, without waiting for explicit instructions from the network. For example, the network configures handover trigger conditions to the terminal via Radio Resource Control (RRC) signaling. The terminal continuously monitors the signal quality of the serving cell and neighboring cells, and automatically initiates handover preparation when the conditions are met. Once the conditions are further met, the terminal immediately performs the handover, reducing signaling interaction latency. If the serving cell signal quality deteriorates further to the execution threshold, the terminal immediately initiates the handover, sends a random access request to the target cell, completes context transmission, releases resources in the original cell, and completes the handover.

[0159] The embodiments disclosed herein can be applied to satellite communications, Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G NR, Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation Radio Access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0160] For some embodiments, the connected state propagation delay difference (PDD) reporting and SMTC adjustment are introduced in the NTN system. In the NTN system, the propagation delay between the satellite and the ground terminal is much higher than that of the terrestrial network, and the high-speed movement of the satellite (the LEO speed is about 7.8 km / s) causes the dynamic change of the delay difference between the serving cell and the neighboring cell (for example, the delay difference between adjacent satellites can reach 4 - 6 ms and continue to drift). The impact is that the traditional static SMTC window (such as the longest 5 ms) cannot cover the dynamically changing SSB reception time of the neighboring cell, resulting in the terminal missing the measurement opportunity.

[0161] For some embodiments, in the terrestrial network (TN), the SMTC is configured based on the serving cell timing. In the NTN, due to the movement of the satellite, there is a significant time offset (time shift) between the arrival time of the neighboring cell SSB and the serving cell SSB, and this offset changes in real time with the satellite position. The terminal measures and reports the propagation delay difference between the serving cell and the neighboring cell, providing a basis for the network device to dynamically adjust the SMTC. Specifically, the terminal combines the ephemeris information (obtained through SIB19 broadcast or RRC signaling, for example) and its own GNSS position to calculate the accurate geometric delay difference.

[0162] For some embodiments, the connected state location-based measurement reporting / CHO execution conditions introduced in the NTN system. In the terrestrial network (TN), the difference in the reference signal received power (RSRP) between the cell edge and the center is significant (usually > 10 dB), which can trigger measurement and handover. However, in the NTN satellite cell (especially LEO), the beam coverage diameter can reach 50 - 100 km, and the difference in RSRP between the cell center and the edge is extremely small (< 3 dB), and the signal strength-based measurement mechanism completely fails.

[0163] For some embodiments, the relative speed of the LEO satellite with respect to the earth's surface is about 7.56 km / s, and the propagation delay changes rapidly (for example, the two-way delay of a 600 km high satellite reaches 25 ms); the service window is short (the single cell residence time is only 6 - 7 seconds). The satellite position changes in real time, and the terminal needs to combine the ephemeris (orbital parameters) and GNSS positioning to calculate the cell coverage boundary and handover timing.

[0164] For some embodiments, in the location-based measurement reporting mechanism, the terminal obtains the longitude and latitude coordinates through GNSS and calculates the straight-line distance (distance) from the reference point (referenceLocation) of the serving cell. For example, when distance (the distance between the terminal and the reference point of the serving cell) > distanceThres (the coverage radius of the serving cell) and distance (the distance between the terminal and the reference point of the neighboring cell) < distanceThres_neighbor (the coverage radius of the neighboring cell), the reporting is triggered.

[0165] In some embodiments, the NTN system adds a location-based condition to the RSRP / RSRQ conditions. For example, when the terminal's location enters a preset handover area of ​​a candidate cell (e.g., the distance to the target cell reference point is <5km), handover is immediately triggered. The location-based condition can be configured independently or simultaneously with the RSRP condition.

[0166] In some embodiments, the above-mentioned SMTC configuration, measurement gap configuration, cell handover condition configuration, etc. are for terminals whose GNSS positioning error meets the protocol index requirements. When the terminal's GNSS positioning error increases (i.e., GNSS positioning accuracy decreases), since the network equipment does not know that the terminal's GNSS positioning error has increased, the original configurations can no longer accurately measure the neighboring cell reference signal or may cause premature / late handover, affecting service quality and user experience.

[0167] To this end, this disclosure proposes a communication scheme in which a network device sends first information to a terminal, and the terminal sends its GNSS positioning error to the network device based on the first information. The GNSS positioning error can be used by the network device to configure reasonable measurement configurations for the terminal, such as SMTC configuration information, measurement gap configuration information, cell handover condition configuration information, etc., to achieve better service cell handover and improve service quality and user experience.

[0168] Figure 2 This is a schematic diagram illustrating a communication method according to an embodiment of the present disclosure. It is used for illustration. Figure 1 Implementation methods of communication systems, such as Figure 2 As shown, the method includes the following steps:

[0169] Step S201: The network device sends the first information to the terminal.

[0170] In some embodiments, the terminal receives first information sent by the network device.

[0171] In some embodiments, the terminal is in RRC connected state.

[0172] In some embodiments, the first information may be configuration information or indication information, etc., and the terminal may send the terminal's GNSS positioning error to the network device based on the first information.

[0173] In some embodiments, the first information may include at least one of the following A, B, and C:

[0174] A. First configuration: This first configuration can be used to configure the type of GNSS positioning error to be transmitted. The terminal can send the terminal's GNSS positioning error to the network device according to the GNSS positioning error type configured by the network device.

[0175] In some examples, the GNSS positioning error type is determined by at least one of the following:

[0176] RMSE (e.g., the terminal determines the GNSS positioning error by calculating the RMSE based on the first configuration, and then sends the GNSS positioning error of this type to the network device); CEP (e.g., the terminal determines the GNSS positioning error by calculating the CEP50 or CEP60 based on the first configuration, and then sends the GNSS positioning error of this type to the network device), etc.

[0177] B. Second configuration: This second configuration can be used to configure the transmission method of GNSS positioning error. The terminal can send the terminal's GNSS positioning error to the network device according to the transmission method configured by the network device.

[0178] C. Third Configuration: This third configuration can be used to configure the transmission of information regarding the availability of GNSS positioning. For example, in scenarios where GNSS positioning is temporarily unavailable or the terminal's GNSS positioning error increases (GNSS positioning accuracy decreases), the network device is configured to configure the terminal to report auxiliary information regarding the availability of GNSS positioning.

[0179] In some examples, when a terminal determines that GNSS positioning is available (i.e., triggers the reporting of GNSS positioning availability information), the terminal can send the GNSS positioning availability information and / or the GNSS positioning error currently obtained by the terminal to the network device, such as through RRC messages and / or MAC CE bearers. Correspondingly, the network device receives the GNSS positioning availability information and / or the GNSS positioning error currently obtained by the terminal.

[0180] In some examples, when a terminal determines that GNSS positioning is unavailable (i.e., triggers the reporting of GNSS positioning unavailable information), the terminal can send GNSS positioning unavailable information and / or estimated unavailability duration information to the network device, such as through RRC messages and / or MAC CE bearers. Correspondingly, the network device receives the GNSS positioning unavailable information and / or estimated unavailability duration information sent by the terminal.

[0181] In some examples, the transmission method of GNSS positioning errors may include at least one of the following: a1, b1, and c1:

[0182] a1. Request-response method, i.e., one-shot reporting, where the terminal sends its GNSS positioning error based on a request from the network device. This method is suitable when the network device detects a problem (such as not receiving the expected neighbor cell measurement reports due to inappropriate SMTC or measurement gap configuration) and wants to adjust the SMTC or measurement gap configuration through a single GNSS positioning error report.

[0183] b1. Periodic transmission mode: The network device can be configured with a corresponding transmission period. For example, the terminal sends the actual GNSS positioning error to the network device at regular intervals according to the transmission period.

[0184] c1. Event-triggered transmission method: Network devices can be configured with corresponding trigger thresholds or ranges. When a terminal determines that a trigger event is met based on the trigger threshold or range, it can send the terminal's actual GNSS positioning error to the network device. This method can save signaling overhead.

[0185] In some examples, the triggering event for the event triggering method includes one of the following: a2, b2, c2, d2, and e2:

[0186] a2. The GNSS positioning error currently obtained by the terminal is higher than a first threshold, which can be configured by the network device. For example, if the GNSS positioning error currently obtained by the terminal is higher than the first threshold, the terminal sends its currently obtained GNSS positioning error to the network device.

[0187] b2. The GNSS positioning error currently obtained by the terminal is lower than the second threshold, which can be configured by the network device. For example, if the GNSS positioning error currently obtained by the terminal is lower than the second threshold, the terminal sends its currently obtained GNSS positioning error to the network device.

[0188] c2. The GNSS positioning error currently obtained by the terminal is within the first error range, which can be configured by the network device. For example, if the GNSS positioning error currently obtained by the terminal is within the first error range, the terminal sends its currently obtained GNSS positioning error to the network device.

[0189] d2. The GNSS positioning error currently obtained by the terminal is outside the second error range. This second error range can be configured by the network device. For example, if the GNSS positioning error currently obtained by the terminal is outside the second error range, the terminal sends its currently obtained GNSS positioning error to the network device.

[0190] e2. The GNSS positioning error currently obtained by the terminal exceeds the third threshold compared to the GNSS positioning error previously transmitted. This third threshold can be configured by the network device. For example, if the GNSS positioning error currently obtained by the terminal exceeds the third threshold compared to the GNSS positioning error previously transmitted, the terminal will send its currently obtained GNSS positioning error to the network device.

[0191] In some embodiments, the first information may be carried by at least one of the following:

[0192] MAC CE; L1 signaling (such as one-time reporting suitable for triggering one-time reporting (a1)); RRC messages (such as RRC reconfiguration messages suitable for configuring one-time reporting (a1), periodic reporting (b1) and event-triggered reporting (c1)), etc.

[0193] In step S202, the terminal sends its GNSS positioning error to the network device based on the first information.

[0194] In some embodiments, the network device receives the GNSS positioning error sent by the terminal based on the first information.

[0195] In some embodiments, the terminal may obtain its own GNSS positioning error, which is affected by many factors, such as signal-to-noise ratio (SNR, which can be used to determine the clarity of the signal), satellite geometric distribution (PDOP, such as the arrangement of satellites above the terminal), number of satellites (such as the more satellites involved in positioning, the more accurate the positioning), number of frequency points, etc.

[0196] In some embodiments, GNSS positioning error can be obtained through at least one of the following:

[0197] RMSE (such as GNSS positioning error calculated from RMSE); CEP (such as GNSS positioning error calculated from CEP50 or CEP60, etc.), etc.

[0198] In some embodiments, the GNSS positioning error of the terminal sent to the network device can be transmitted via MAC CE and / or RRC messages, for example, through measurement reporting or UE assistance information (UAI) to the network device.

[0199] In some embodiments, the GNSS positioning error sent by the terminal can be used to determine measurement configuration information for the measurement of the serving cell and / or neighboring cells.

[0200] In some examples, the measurement configuration information may include at least one of the following:

[0201] SMTC configuration information; measurement gap configuration information; cell handover condition configuration information, etc.

[0202] In this way, network devices configure reasonable measurement settings for the terminal based on its GNSS positioning error, such as SMTC configuration information, measurement gap configuration information, and cell handover condition configuration information.

[0203] In some embodiments, after the terminal sends its GNSS positioning error to the network device, the network device can adjust the configuration of the SMTC, and / or the measurement gap, and / or the cell handover conditions based on the GNSS positioning error, and then send the adjusted configuration to the terminal. For example, when the terminal reports a deterioration in GNSS positioning accuracy to the network device, the network device can configure a longer-duration SMTC and measurement gap configuration so that the terminal can measure neighboring cell reference signals; or for cell handover, the network device can configure a stricter distance threshold for neighboring cells or simultaneously configure RSRP-based execution conditions to correct errors in location-based execution conditions.

[0204] The communication method involved in this embodiment may include at least one of steps S201 to S202. For example, step S201 may be implemented as a standalone embodiment; or step S202 may be implemented as a standalone embodiment. In addition, some or all of the steps in steps S201 to S202 may be combined as a standalone embodiment, and this embodiment does not limit this.

[0205] This disclosure proposes a communication scheme that allows network devices to configure reasonable measurement settings for connected terminals based on the GNSS positioning errors reported by the terminals, such as SMTC configuration information, measurement gap configuration information, and cell handover condition configuration information, in order to achieve better service cell handover and improve service quality and user experience.

[0206] Figure 3 This is a schematic diagram illustrating a communication method according to an embodiment of this disclosure. For example... Figure 3 As shown, the method includes:

[0207] Step S301: The network device sends configuration information to the terminal.

[0208] In some embodiments, the terminal receives configuration information sent by the network device.

[0209] In some embodiments, the configuration information may include at least one of the following:

[0210] A. First configuration, which can be used to configure the type of GNSS positioning error transmitted.

[0211] B. Second configuration, which can be used to configure the transmission method of GNSS positioning errors.

[0212] C. Third configuration, which can be used to configure whether GNSS positioning is available.

[0213] In step S302, the terminal sends its GNSS positioning error to the network device based on the configuration information.

[0214] In some embodiments, the terminal may send its GNSS positioning error to the network device according to the GNSS positioning error type configured in the network device.

[0215] In some embodiments, the terminal may send its GNSS positioning error to the network device according to the transmission method configured by the network device.

[0216] In some embodiments, when a terminal determines that GNSS positioning is available (i.e., triggers the reporting of GNSS positioning availability information), the terminal may send the GNSS positioning availability information and / or the GNSS positioning error currently obtained by the terminal to the network device, such as through RRC messages and / or MAC CE bearers. Correspondingly, the network device receives the GNSS positioning availability information and / or the GNSS positioning error currently obtained by the terminal sent by the terminal.

[0217] In some embodiments, when a terminal determines that GNSS positioning is unavailable (i.e., triggers the reporting of GNSS positioning unavailable information), the terminal may send GNSS positioning unavailable information and / or estimated unavailability duration information to the network device, such as through RRC messages and / or MAC CE bearers. Correspondingly, the network device receives the GNSS positioning unavailable information and / or estimated unavailability duration information sent by the terminal.

[0218] Optionally, alternative implementations of steps S301 and S302 can be found in other alternative implementations involved in steps S201 to S202, which will not be repeated here.

[0219] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0220] The communication method involved in the embodiments of this disclosure may include at least one of steps S301 to S302. For example, step S301 may be implemented as a standalone embodiment; or step S302 may be implemented as a standalone embodiment. In addition, some or all of the steps in steps S301 to S302 may be combined as standalone embodiments, and this embodiment does not limit this.

[0221] This disclosure proposes a communication scheme that allows network devices to configure reasonable measurement settings for connected terminals based on the GNSS positioning errors reported by the terminals, such as SMTC configuration information, measurement gap configuration information, and cell handover condition configuration information, in order to achieve better service cell handover and improve service quality and user experience.

[0222] The following are some exemplary specific solutions proposed in the embodiments of this disclosure:

[0223] This disclosure proposes a method for a terminal in RRC connected state (or simply a connected state terminal) to report GNSS positioning accuracy auxiliary information. By reporting GNSS positioning accuracy, the method assists network devices in configuring reasonable SMTC configuration and measurement gap configuration, as well as configuring reasonable handover execution conditions.

[0224] As an optional method: GNSS positioning accuracy reporting by connected terminals. Connected terminals receive configuration information from network devices, which instructs the terminals to report GNSS positioning accuracy.

[0225] In some embodiments, the network device indicates the type of GNSS positioning error reported by the terminal, such as root mean square error (RMSE), circular error probable (CEP) 50, or CEP 60, etc.

[0226] In some embodiments, the network device instructs the terminal to report GNSS positioning accuracy in a certain way. In some examples, the reporting method can be request-response, i.e., one-shot reporting. (This method is suitable when the network discovers a problem (e.g., due to an inappropriate SMTC / measurement gap configuration, the expected neighbor cell measurement reports are not received) and expects to adjust the SMTC / measurement gap through a single positioning accuracy report.)

[0227] In some examples, the reporting method can be periodic reporting, with the network device configured with a corresponding reporting period. This method is simple to implement.

[0228] In some examples, the reporting method can be event-triggered reporting (saving signaling overhead), with the network device configured with a corresponding trigger threshold or range. Triggering events can be achieved in the following ways:

[0229] When the currently obtained GNSS positioning error is higher than the pre-configured threshold, the terminal sends the currently obtained GNSS positioning error to the network device.

[0230] When the currently obtained GNSS positioning error is lower than the pre-configured threshold, the terminal sends the currently obtained GNSS positioning error to the network device.

[0231] When the currently obtained GNSS positioning error falls within the pre-configured error range, the terminal sends the currently obtained GNSS positioning error to the network device.

[0232] When the currently obtained GNSS positioning error deviates from the pre-configured error range, the terminal sends the currently obtained GNSS positioning error to the network device.

[0233] When the currently obtained GNSS positioning error exceeds a pre-configured threshold compared to the GNSS positioning error previously reported by the terminal, the terminal sends the currently obtained GNSS positioning error to the network device.

[0234] In some embodiments, configuration information can be sent via MAC CE or L1 signaling (suitable for triggering one-time reporting) or RRC messages (e.g., RRC reconfiguration messages, suitable for configuring one-time reporting, periodic reporting, and event-triggered reporting).

[0235] In some embodiments, the GNSS positioning accuracy / error acquired by the connected terminal is affected by factors such as signal-to-noise ratio (SNR), position dilution of precision (PDOP), number of satellites, and number of frequency points. The terminal reports the GNSS positioning error when it determines that the conditions are met based on the network device configuration. The reporting signaling can be a MACCE or RRC message (e.g., UAI (UE assistance information), measurement reporting, etc.).

[0236] In some embodiments, after the terminal reports GNSS positioning accuracy, the terminal may receive adjusted SMTC / CHO execution conditions from the network device. For example, when the terminal reports a deterioration in positioning accuracy, the network device may configure a longer duration SMTC and measurement gap so that the terminal can measure neighboring cell reference signals; for cell handover, the network device may configure stricter distance thresholds for neighboring cells or simultaneously configure RSRP-based execution conditions to correct errors in location-based execution conditions.

[0237] As an alternative, the GNSS positioning status of the connected terminal is reported as available / unavailable.

[0238] In some embodiments, for scenarios involving temporary GNSS positioning unavailability and decreased GNSS positioning accuracy, network devices can be configured to allow terminals to report auxiliary information regarding GNSS positioning availability / unavailability. When a terminal triggers the reporting of GNSS availability information, it can append the currently acquired GNSS positioning accuracy / error information; when a terminal triggers the reporting of GNSS unavailability information, it can append the estimated duration of unavailability. Configuration and reporting can be implemented via signaling such as RRC / MAC CE.

[0239] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0240] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0241] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
