Description

[Technical Field]

[0001] FIELD Embodiments of the present disclosure relate generally to the field of telecommunications, and more particularly to a communication method, apparatus, and computer storage medium for measurement reporting. [Background technology]

[0002] For airborne user equipment (UE), such as an unmanned aerial vehicle (UAV), if its height is lower than that of the network equipment, its radio characteristics are similar to those of ground-based UEs, i.e., multipath transmission and limited nearby interference. If its height is higher than that of the network equipment, its radio characteristics are different from those of ground-based UEs (e.g., line-of-sight transmission and strong nearby interference). Airborne UEs can detect more cells with similar signal strength and can detect more distant cells than ground-based UEs. In this case, measurement reports are triggered more frequently, which may increase signaling interference. Summary of the Invention [Problem to be solved by the invention]

[0031] The principles of the present disclosure will now be described with reference to some exemplary embodiments. It should be understood that these embodiments are set forth for illustrative purposes only and are intended to aid those skilled in the art in understanding and practicing the present disclosure, without implying any limitation on the scope of the present disclosure. The embodiments described herein can be implemented in a variety of ways other than those described below.

[0032] In the following description and claims, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Furthermore, communications between terminal devices and network devices within a communication network may be performed according to any appropriate generation of communication protocol, including, but not limited to, first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, fifth-generation (5G), 5.5G, 5G-Advanced, or sixth-generation (6G) communication protocols, and / or other protocols currently known or developed in the future. Embodiments of the present disclosure may be applied to various communication systems. Given the rapid development of communications, there will naturally be future types of communication technologies and systems in which the present disclosure may be embodied. The scope of the present disclosure should not be considered limited to only the aforementioned systems.

[0038] As used herein, the term "terminal device" refers to any device with wireless or wired communication capabilities. Examples of terminal devices include User Equipment (UE), personal computers, desktops, mobile phones, cellular phones, smartphones, personal digital assistants (PDAs), portable computers, tablets, wearable devices, Internet of Things (IoT) devices, Ultra-Reliable and Low Latency Communications (URLLC) devices, Internet of Everything (IoE) devices, Machine Type Communication (MTC) devices, vehicle-mounted devices for V2X communications (where X means pedestrian, vehicle, or infrastructure / network), Integrated Access and Backhaul (IAB) devices, spacecraft or airborne vehicles in Non-Terrestrial Networks (NTN) including satellites and High Altitude Platforms (HAPs) including Unmanned Aircraft Systems (UASs), Augmented Reality (AR), Mixed Reality (MR), and other technologies. These include, but are not limited to, extended reality (XR) devices, which include various types of reality such as real reality (VR) and virtual reality (VR), unmanned aerial vehicles (UAVs), which are aircraft without a human pilot, commonly known as drones, high speed train (HST) mounted devices, image capture devices such as digital cameras, sensors, game consoles, music storage and playback devices, or internet appliances that enable wireless or wired internet access and browsing.Additionally, a "terminal device" may have "multicast / broadcast" features to support public safety and mission-critical, V2X applications, transparent IPv4 / IPv6 multicast distribution, IPTV, smart TV, radio services, over-the-air software distribution, group communication, and IoT applications. It may also incorporate one or more subscriber identity modules (SIMs), known as multi-SIM. The term "terminal device" may be used interchangeably with UE, mobile station, subscriber station, mobile terminal, user terminal, or wireless device.

[0039] The term "network device," as used herein, refers to a device that can provide or host a cell or coverage area over which terminal devices can communicate. Examples of network devices include, but are not limited to, satellites, unmanned aerial systems (UAS) platforms, Node Bs (Node Bs or NBs), evolved Node Bs (eNode Bs or eNBs), next-generation Node Bs (gNBs), transmission reception points (TRPs), remote radio units (RRUs), radio heads (RHs), remote radio heads (RRHs), IAB nodes, low-power nodes such as femto nodes, pico nodes, and reconfigurable intelligent surfaces (RISs).

[0040] Terminal devices or network devices may be equipped with artificial intelligence (AI) or machine learning capabilities, which typically involve models trained from a large amount of collected data for a specific function and can be used to predict some information.

[0041] A terminal or network device can operate in multiple frequency ranges, such as FR1 (410 MHz to 7125 MHz), FR2 (24.25 GHz to 71 GHz), frequency bands above 100 GHz, and terahertz (THz). It can also operate in licensed, unlicensed, and shared spectrum. In a Multi-Radio Dual Connectivity (MR-DC) application scenario, a terminal device may have multiple connections with a network device. The terminal or network device can operate in full duplex, flexible duplex, and cross-division duplex modes.

[0042] Embodiments of the present disclosure may be implemented in test equipment such as signal generators, signal analyzers, spectrum analyzers, network analyzers, test terminal equipment, test network equipment, channel emulators, and the like.

[0043] As mentioned above, due to line-of-sight transmission and strong nearby interference, an airborne UE may detect more cells of similar signal strength and cells that are further away than a terrestrial UE, which may result in more frequent measurement reports and increased signaling interference.

[0044] In consideration of this, embodiments of the present disclosure provide a communication solution for measurement reports to solve the above and other potential problems. In one aspect, if a measurement value of a first cell satisfies a first condition, the terminal device includes the first cell in a first list. If the first list satisfies a second condition associated with a set of cells of interest, the terminal device transmits a measurement report. In this manner, delays in measurement reports can be avoided.

[0045] In another aspect, if the measurement value of a first cell satisfies a first condition, the terminal device includes the first cell in a first list. If the measurement value of a second cell in the first list satisfies a third condition, the terminal device includes the second cell in a second list. If the second list satisfies a fourth condition, the terminal device transmits a measurement report. This method can avoid frequent measurement reports due to the achievement of an end condition for a measurement event.

[0046] In yet another aspect, if the measurement value of the beam of the third cell satisfies a fifth condition, the terminal device includes the beam in a third list. If the third list satisfies a sixth condition, the terminal device transmits a measurement report. This method can avoid frequent measurement reports due to the presence of more cells at high altitudes.

[0047] In yet another aspect, the terminal device determines an eighth condition based on at least one of the beam measurements or the height of the terminal device. If the measurement of the fourth cell satisfies the eighth condition, the terminal device includes the fourth cell in the fifth list to trigger a measurement report. In this manner, the trigger condition can be adapted to avoid frequent measurement reports due to more cells being seen at high altitudes.

[0048] The principles and embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. <Example of a communication network>

[0049] 1 illustrates an exemplary communication environment 100 in which exemplary embodiments of the present disclosure may be implemented. Network environment 100 includes a terminal device 110 and a network device 120 that serves terminal device 110. Network device 120 may provide one or more cells to terminal device 110 or other terminal devices not shown. In the example of FIG. 1, network device 120 provides a serving cell 121 at an altitude above network device 120.

[0050] For convenience, the following description assumes that terminal device 110 is within serving cell 121 of network device 120. In the example of Figure 1, terminal device 110 is shown as an airborne terminal. It should be understood that embodiments of the present disclosure also apply to terrestrial terminals.

[0051] When the terminal device 110 is within the serving cell 121 of the network device 120, the terminal device 110 can communicate with the network device 120 via a service link, a radio link, etc. Communication in the direction from the terminal device 110 to the network device 120 is called UL communication, and communication in the reverse direction from the network device 120 to the terminal device 110 is called DL communication.

[0052] Communications in communication environment 100 may conform to any suitable standard, including, but not limited to, Long Term Evolution (LTE), LTE-Evolution, LTE-Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), and Global System for Mobile Communications (GSM). Furthermore, communications may be performed according to any currently known or future-developed generation of communications protocols. Examples of communications protocols include, but are not limited to, first-generation (1G), second-generation (2G), 2.5G, 2.75G, third-generation (3G), fourth-generation (4G), 4.5G, fifth-generation (5G), 5.5G, 5G-Advanced, or sixth-generation (6G) communications protocols.

[0053] It should be understood that the number of and connectivity between network devices, terminal devices, and serving cells is for illustrative purposes only, without implying any limitation. Communications environment 100 may include any suitable access network devices, terminal devices, and serving cells adapted to implement embodiments of the present disclosure.

[0054] In some scenarios, terminal device 110 may receive a measurement configuration from network device 120 and perform radio measurements based on the measurement configuration. Terminal device 110 may then report results of the radio measurements to network device 120.

[0055] In some embodiments, the terminal device 110 can derive cell measurements by measuring one or more beams associated with each cell configured by the network. For all cell measurements, the terminal device 110 can apply Layer 3 filtering before using the measurement to evaluate reporting criteria. For cell measurements, the network device 120 can configure Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), Receive Signal Channel Power (RSCP), or the ratio of energy per modulation bit to noise spectral density Ec / N0 (EcN0) as trigger quantities. For cell and beam measurements, the reporting quantity may be any combination of quantities (i.e., RSRP only; RSRQ only; SINR only; RSRP and RSRQ; RSRP and SINR; RSRQ and SINR; RSRP, RSRQ and SINR; RSCP only; EcN0 only; RSCP and EcN0). In some embodiments, Layer 3 beam-filtered measurements may be derived based on the Synchronization Signal and Physical Broadcast CHannel (SS / PBCH) block or the Channel State Information Reference Signal (CSI-RS).

[0056] In some embodiments, if one or more cells trigger a measurement event, the terminal device 110 may initiate a measurement reporting procedure. In some embodiments, the measurement event may include at least one of event A3 (neighbor offset becomes better than SpCell), event A4 (neighbor offset becomes better than a threshold), event A5 (SpCell becomes worse than threshold 1 and neighbor offset becomes better than threshold 2), A6 (neighbor offset becomes better than SCell), B1 (inter-RAT neighbor offset becomes better than a threshold), or B2 (PCell becomes worse than threshold 1 and inter-RAT neighbor offset becomes better than threshold 2). It should be noted that the present application is not limited to the above measurement events and corresponding start and stop conditions, and any suitable measurement event and corresponding start and stop conditions, existing or developed in the future, are possible.

[0057] Embodiments of the present disclosure provide a communication solution for measurement reporting, which will be explained in detail with reference to Figures 2 to 8. Example of a Report Based on a Set of Cells of Interest

[0058] 2 is a schematic diagram illustrating a communication process 200 for measurement reporting according to an embodiment of the present disclosure. For clarity, the process 200 will be described with reference to FIG. 1. The process 200 may include a terminal device 110 and a network device 120, as shown in FIG. 1.

[0059] As shown in FIG. 2 , network device 120 transmits (210) a measurement configuration to terminal device 110. In some embodiments, the measurement configuration indicates a start condition for a measurement event (also referred to herein as a first condition for convenience) and a trigger condition for a measurement report (also referred to herein as a second condition for convenience), where the trigger condition is associated with the start condition. The trigger condition is associated with a set of cells of interest. In some embodiments, the measurement configuration may include the set of cells of interest. It should be understood that the measurement configuration may also include any other suitable information.

[0060] Based on the measurement configuration, terminal device 110 can perform radio measurements.

[0061] Referring to FIG. 2, if the measurements of a cell (for convenience, also referred to herein as the first cell) satisfy the starting condition, the terminal device 110 may include (220) the first cell in a list (for convenience, also referred to herein as the first list).

[0062] Continuing with reference to FIG. 2, the terminal device may determine 220 whether the first list satisfies a trigger condition associated with a set of cells of interest. If the first list satisfies the trigger condition, the terminal device 110 may transmit 230 a measurement report. For clarity, some exemplary embodiments will be described in relation to embodiments 1-3. <Embodiment 1>

[0063] In this embodiment, the set of cells of interest may be the set of configured cells.

[0064] In some embodiments, if the number of cells in the first list is less than a predetermined number (also referred to herein as the first predetermined number for convenience) and the first cell is indicated in the set of cells of interest, terminal device 110 can determine that the trigger condition is met. In some embodiments, if the number of cells other than the first cell in the first list is equal to or greater than the first predetermined number and the first cell is indicated in the set of cells of interest, terminal device 110 can determine that the trigger condition is met.

[0065] 3A is a schematic diagram illustrating an example process 300A for measurement reporting based on a set of cells of interest, in accordance with some embodiments of the present disclosure. As shown in FIG. 3A, in step 310, the terminal device 110 may determine that a cell satisfies a trigger condition for event X.

[0066] In step 311, terminal device 110 may determine whether the number of cells in the list to which cells have not been added (e.g., cellTriggeredList) is greater than or equal to a predetermined number (e.g., numberOfTriggeringCells). If the number of cells in the list to which cells have not been added is less than the predetermined number, process 300A may proceed to step 312.

[0067] In step 312, terminal device 110 may add a cell to the list. In step 313, terminal device 110 may determine whether the number of cells in the list to which the cell was added is greater than or equal to a predetermined number. If the number of cells in the list to which the cell was added is less than the predetermined number, process 300A may proceed to step 314. In step 314, terminal device 110 may determine whether the first cell is indicated in a set of cells of interest. If the first cell is indicated in the set of cells of interest, process 300A may proceed to step 315. In step 315, terminal device 110 may initiate measurement reporting.

[0068] Returning to step 313, if the number of cells in the list to which the cell was added is greater than or equal to the predetermined number, process 300A may proceed to step 316. In step 316, terminal device 110 may initiate measurement reporting.

[0069] Returning to step 311, if the number of cells in the list to which a cell has not been added is greater than or equal to the predetermined number, process 300A may proceed to step 317. In step 317, terminal device 110 may add a cell to the list. In step 318, terminal device 110 may determine whether the first cell is indicated in the set of cells of interest. If the first cell is indicated in the set of cells of interest, process 300A may proceed to step 319. In step 319, terminal device 110 may initiate measurement reporting.

[0070] It should be understood that Figure 3A is for illustrative purposes only and is not intended to be limiting. For example, one of steps 314 and 318 in Figure 3A can be omitted. In some alternative embodiments, once it is determined that the first cell satisfies the trigger condition, terminal device 110 can determine whether the first cell is indicated in a set of cells of interest. If the first cell is indicated in the set of cells of interest, terminal device 110 can determine that the trigger condition is met. A measurement report is then transmitted.

[0071] In some embodiments, terminal device 110 can include fight path information in the measurement report. In some embodiments, the fight path information can be used to determine a set of cells configured by network device 120 (i.e., a set of cells of interest). In this manner, fight path information can be provided to network device 120 for handover decisions. <Embodiment 2>

[0072] In this embodiment, the set of cells of interest may be indicated by the cell weights.

[0073] In some embodiments, terminal device 110 can determine the weight of a cell in the first list, for example, from a configured set of cell weights. In some embodiments, for cells not configured with a weight, terminal device 110 can assume that the cell weight is a default value. For example, the default value may be 1 unit. It will be understood that other suitable values ​​are also possible.

[0074] If the sum of the weights of the cells in the first list (denoted herein as triggerValue) is greater than or equal to a predetermined value (also referred to herein as the first predetermined value for convenience), terminal device 110 may determine that a trigger condition is met and may transmit a measurement report (denoted herein as MR). In some embodiments, upon transmitting the measurement report, terminal device 110 may reset the sum of the weights, e.g., to zero or other suitable value. In this manner, a measurement report may be initiated whenever the sum of the weights of the cells in the first list is greater than or equal to the predetermined value.

[0075] For clarity, an example procedure can be described as follows: 2>If triggerType is set to event and the entry condition applicable to this event (i.e. the event corresponding to the eventId of the corresponding reportConfig in VarMeasConfig) is met for one or more applicable cells for all measurements after layer 3 filtering performed during the timeToTrigger defined for this event in VarMeasConfig: 3>If VarMeasReportList does not contain a measurement report entry for this measId: 4>Include a measurement report entry in VarMeasReportList for this measId; 3>Include the cells involved in the cellsTriggeredList defined in the VarMeasReportList for this measId; 3> If triggerWeight is set on the relevant cell 4>Increment triggerValue by the value of triggerWeight; 3> Otherwise 4>Increment triggerValue by the default value (i.e. 1); 3>If triggerValue is greater than or equal to triggerThreshold: 4>Initiate measurement reporting procedure; (4>Set triggerValue for this measId to 0) - Optional.

[0076] In some embodiments, if the sum of the weights of cells other than the first cell in the first list is less than a first predetermined value, terminal device 110 may add the first cell in the first list and determine whether the sum of the weights of the cells in the first list to which the first cell was added is greater than or equal to the first predetermined value. If the sum of the weights of the cells in the first list to which the first cell was added is greater than or equal to the first predetermined value, terminal device 110 may determine that a trigger condition is met. A measurement report may then be triggered. In this manner, once a measurement report is triggered, terminal device 110 does not continuously trigger a measurement report after the sum of the weights falls below the predetermined value unless the predetermined value of the sum of the weights is met again.

[0077] In some embodiments, if a cell in the first list satisfies the termination condition of the measurement event, the weight of that cell is subtracted from the sum of the weights of the cells in the first list.

[0078] For clarity, an example procedure can be described as follows: 2>If triggerType is set to event and the entry condition applicable to this event (i.e. the event corresponding to the eventId of the corresponding reportConfig in VarMeasConfig) is met for one or more applicable cells for all measurements after layer 3 filtering performed during the timeToTrigger defined for this event in VarMeasConfig: 3>If VarMeasReportList does not contain a measurement report entry for this measId: 4>Include a measurement report entry in VarMeasReportList for this measId; 3>Include the cells involved in the cellsTriggeredList defined in the VarMeasReportList for this measId; 3> If triggerValue (the sum of triggerWeight of all cells in cellsTriggeredList) is greater than or equal to triggerThreshold 4> If triggerWeight is set on the relevant cell 5>Increment triggerValue by the value of triggerWeight; 4> Otherwise 5>Increment triggerValue by the default value (i.e. 1); 3> Otherwise: 4> If the cell involved has a triggerWeight set: 5>Increment triggerValue by the value of triggerWeight; 4> Otherwise 5>Increment triggerValue by the default value (i.e. 1); 4>If triggerValue is greater than or equal to triggerThreshold: 5>Set numberOfReportsSent defined in VarMeasReportList for this measId to 0; 5>Initiate measurement reporting procedure.

[0079] 3B is a schematic diagram illustrating an example process 300B for cell weight-based measurement reporting in accordance with some embodiments of the present disclosure. As shown in FIG. 3B, at step 320, the terminal device 110 may determine that the cell satisfies a start condition for event X.

[0080] In step 321, terminal device 110 may determine whether the sum of the weights of the cells in the list to which cells have not been added (e.g., cellTriggeredList) is greater than or equal to a predetermined value (e.g., triggerThreshold). If the sum of the weights of the cells in the list to which cells have not been added is less than the predetermined value, process 300B may proceed to step 322.

[0081] In step 322, terminal device 110 may add the cell to the list. In step 323, terminal device 110 may determine whether the sum of the weights of the cells in the list to which the cell was added is greater than or equal to a predetermined value. If the sum of the weights of the cells in the list to which the cell was added is greater than or equal to the predetermined value, process 300B may proceed to step 324. In step 324, terminal device 110 may initiate measurement reporting.

[0082] Returning to step 321, if the number of cells in the list to which the cell has not been added is greater than or equal to the predetermined number, process 300B may proceed to step 325. In step 325, terminal device 110 may add the cell to a list (e.g., cellTriggeredList).

[0083] It should be understood that FIG. 3B is for illustrative purposes only and is not intended to be limiting.

[0084] Table 1 below shows a comparison example between the above measurement reporting solutions based on cell weights, where triggerThreshold=6. Table 1 JPEG2025533610000002.jpg98167Op1: If the first cell satisfies the start condition, if the sum of the weights of the cells in the list to which the first cell is not added is less than a predetermined value and the sum of the weights of the cells in the first list to which the first cell is added is greater than or equal to a predetermined value, measurement reporting is started; Op2: If the first cell satisfies the initiation condition, measurement reporting is initiated if the sum of the weights of the cells in the first list to which the first cell is added is greater than or equal to a predetermined value; Op3: If the first cell satisfies the start condition, the measurement report is started if the sum of the weights of the cells in the first list to which the first cell is added is equal to or greater than a predetermined value. After sending the measurement report, the sum of the weights is reset to 0. <Embodiment 3>

If the number of cells in the list to which the cell was added is less than the predetermined number, process 300C may proceed to step 334. In step 334, terminal device 110 may determine whether the quality of the first cell is higher than the quality of other cells (e.g., the best cell) in the first list. If the quality of the first cell is higher than the quality of other cells (e.g., the best cell), process 300C may proceed to step 335. In step 335, terminal device 110 may initiate measurement reporting.

For clarity, the process 400 will be described with reference to FIG. 1. The process 400 may include a terminal device 110 and a network device 120, as shown in FIG. 1.

[0097] 4, network device 120 transmits (410) a measurement configuration to terminal device 110. In some embodiments, the measurement configuration indicates a start condition (also referred to herein as a first condition for convenience), an end condition (also referred to herein as a third condition for convenience), and a trigger condition (also referred to herein as a fourth condition for convenience) for a measurement report, the trigger condition being associated with the end condition. It should be understood that the measurement configuration may also include any other suitable information.

[0098] Based on the measurement configuration, terminal device 110 can perform radio measurements. Referring to FIG. 4, terminal device 110 determines whether the measurement values ​​of a cell (also referred to herein as a first cell for convenience) satisfy a starting condition (420). If the measurement values ​​of the first cell satisfy the starting condition, terminal device 110 can include the first cell in a list (also referred to herein as a first list for convenience) (430). It should be noted that the present application does not limit the starting condition, and any suitable condition is possible.

[0099] 4, terminal device 110 determines whether measurements of a cell in the first list (also referred to herein as the second cell for convenience) satisfy an exit condition (440). If the measurements of the second cell satisfy the exit condition, terminal device 110 may include (450) the second cell in a list (also referred to herein as the second list or exit cell list for convenience). In some embodiments, if the second cell was reported in a previous measurement report (e.g., the most recent measurement report), terminal device 110 may determine that the exit condition is met and add the second cell to the second list.

[0100] 4, terminal device 110 determines whether the second list satisfies a trigger condition (460). If the second list satisfies the trigger condition, terminal device 110 transmits a measurement report (470). In some embodiments, if the second list satisfies the trigger condition, terminal device 110 may also empty the second list, e.g., delete all items in the second list.

[0101] In some embodiments, if a cell in the second list again satisfies the entry condition, the cell may be removed from the second list and added to the first list.

[0102] For clarity, some exemplary embodiments will be described in relation to embodiments 4-8. <Embodiment 4>

[0103] In this embodiment, the trigger condition is associated with the ending cell list.

As shown in FIG. 5A, at step 510, the terminal device 110 may determine that a cell satisfies an exit condition for event Y.

[0106] At step 511, terminal device 110 may remove the second cell from the first list. At step 512, terminal device 110 may include the second cell in the second list. At step 513, terminal device 110 may determine whether the number of cells in the second list (e.g., cellsLeavingList) to which the second cell was added is greater than or equal to a predetermined number (e.g., numberOfLeavingCells). If the number of cells in the second list to which the cell was added is greater than or equal to the predetermined number, process 500A may proceed to step 514. At step 514, terminal device 110 may start measurement reporting. At step 515, terminal device 110 may empty the second list.

[0107] 5A is for illustrative purposes only and is not intended to be limiting. In some alternative embodiments, if the number of cells in the second list is greater than or equal to a second predetermined number and at least one cell in the second list has been reported in a previous measurement report (e.g., the most recent measurement report), terminal device 110 may determine that a trigger condition is met and transmit a measurement report.

[0108] Table 2 below shows an example comparison between a conventional solution without an ending cell list and the current solution based on an ending cell list. In this example, numberOfLeavingCells=2. Table 2 JPEG2025533610000003.jpg58167Op1: If the number of cells in the end cell list is greater than or equal to a predetermined value, measurement reporting is initiated; Op2: If the number of cells in the ending cell list is equal to or greater than a predetermined value and at least one of the cells in the ending cell list has been triggered or reported in a previous measurement report, a measurement report is initiated. <Embodiment 5>

[0109] In this embodiment, the trigger condition is associated with at least one of a terminating cell list or a timer (also referred to herein as a report delay timer).

[0110] In some embodiments, if the second list is empty, terminal device 110 may start a timer when the second cell is added to the second list. In some embodiments, if the timer expires, terminal device 110 may determine that a trigger condition is met and may send a measurement report.

[0111] 5B is a schematic diagram illustrating another example process 500B for measurement reporting based on a terminating cell list, in accordance with some embodiments of the present disclosure. As shown in FIG. 5B, at step 520, the terminal device 110 may determine that a cell satisfies an exit condition for event Y.

[0112] In step 521, terminal device 110 may delete the second cell from the first list. In step 522, terminal device 110 may include the second cell in the second list. If the second list is empty, terminal device 110 may start a timer. Upon sending the measurement report, terminal device 110 may stop the timer if it is running.

[0113] In step 523, terminal device 110 may determine whether the number of cells in the second list (e.g., cellsLeavingList) to which the second cell was added is greater than or equal to a predetermined number (e.g., numberOfLeavingCells). If the number of cells in the second list to which the cell was added is greater than or equal to the predetermined number, process 500A may proceed to step 524. In step 524, terminal device 110 may initiate measurement reporting. In step 525, terminal device 110 may empty the second list. This disclosure does not limit the order of steps 524 and 525.

[0114] Returning to step 523, if the number of cells in the second list to which the second cell was added is less than the predetermined number, process 500B may proceed to step 526. In step 526, terminal device 110 may determine whether a timer has expired. If the timer has expired, process 500B may proceed to step 527. In step 527, terminal device 110 may initiate measurement reporting. In step 528, terminal device 110 may empty the second list. This disclosure does not limit the order of steps 527 and 528.

[0115] It should be understood that Figure 5B is for illustrative purposes only and is not intended to be limiting. In some alternative embodiments, if the number of cells in the second list to which the second cell was added is greater than or equal to the second predetermined number and the timer is running, terminal device 110 may determine that a trigger condition is met and send a measurement report.

[0116] For clarity, an example of the operation of the timer can be explained as follows: - Report delay timer starts: when the first relevant cell is included in the cellsLeavingList If the cellsLeavingList defined in the VarMeasReportList for this measId is empty, Include cells related to the cellsTriggeredList defined in the VarMeasReportList for this measId; Start or restart the reporting delay timer; - Stop Report Delay Timer: When starting the measurement reporting procedure for this event, stop the reporting delay timer (if running); - Report delay timer expires: Option 1: When the reporting delay timer expires, the measurement reporting procedure for this event begins. Option 2: If the number of cells in cellsLeavingList is greater than or equal to numberOfTriggeringCells, or the reporting delay timer (if configured) has not run: Initiate the measurement reporting procedure. <Embodiment 6>

[0117] In this embodiment, the trigger condition is associated with an ending cell list and a set of cells of interest.

[0118] In some embodiments, if the second cell is indicated in the set of cells of interest, terminal device 110 may determine that a trigger condition is met.

[0119] In some embodiments, if the number of cells in the second list is less than a second predetermined number and the second cell is indicated in the set of cells of interest, terminal device 110 may determine that the trigger condition is met.

[0120] In some embodiments, if the number of cells other than the second cell in the second list is greater than or equal to a second predetermined number and the second cell is indicated in the set of cells of interest, terminal device 110 may determine that the trigger condition is met.

[0121] 5C is a schematic diagram illustrating an example process 500C for measurement reporting based on a termination cell list and a set of cells of interest, in accordance with some embodiments of the present disclosure. As shown in FIG. 5C, at step 530, the terminal device 110 may determine that a cell satisfies an termination condition for event Y.

[0122] In step 531, terminal device 110 may remove the second cell from the first list.

[0123] In step 532, terminal device 110 may determine whether the second cell is indicated in the set of cells of interest. If the second cell is indicated in the set of cells of interest, process 500C may proceed to step 533. In step 533, terminal device 110 may determine that a trigger condition is met and may initiate measurement reporting.

[0124] Returning to step 532, if the second cell is not indicated in the set of cells of interest, process 500C may proceed to step 534. In step 534, terminal device 110 may add the second cell to the second list. In step 535, terminal device 110 may determine whether the number of cells in the second list (e.g., cellsLeavingList) to which the second cell was added is greater than or equal to a predetermined number (e.g., numberOfLeavingCells). If the number of cells in the second list to which the second cell was added is greater than or equal to the predetermined number, process 500C may proceed to step 536. In step 536, terminal device 110 may determine that a trigger condition is met and may initiate measurement reporting. In step 537, terminal device 110 may empty the second list.

[0125] It should be understood that FIG. 5C is for illustrative purposes only and is not intended to be limiting. <Embodiment 7>

[0126] In this embodiment, the trigger condition is associated with the ending cell list and the weight of the cell.

[0127] In some embodiments, terminal device 110 can determine weights of cells in the second list. If the sum of the weights of cells in the second list with or without the second cell added is greater than or equal to a predetermined value (also referred to herein as a second predetermined value for convenience), terminal device 110 can determine that a trigger condition is met and can transmit a measurement report.

[0128] In some embodiments, if the sum of the weights of cells other than the second cell in the second list is less than a second predetermined value and the sum of the weights of cells in the second list to which the second cell has been added is greater than or equal to the second predetermined value, the terminal device 110 can determine that the trigger condition is met and transmit a measurement report.

[0129] In some embodiments, upon transmission of a measurement report, terminal device 110 may reset the sum of the weights.

[0130] 5D is a schematic diagram illustrating an example process 500D for measurement reporting based on a termination cell list and cell weights, in accordance with some embodiments of the present disclosure. As shown in FIG. 5D, at step 540, the terminal device 110 may determine that a cell satisfies an termination condition for event Y.

[0131] In step 541, terminal device 110 may delete the second cell from the first list. In step 542, terminal device 110 may add the second cell to the second list. In step 543, terminal device 110 may determine whether the sum of the weights of the cells in the list to which the second cell was added is greater than or equal to a predetermined value. If the sum of the weights of the cells in the list to which the second cell was added is greater than or equal to the predetermined value, process 500D may proceed to step 544. In step 544, terminal device 110 may start measurement reporting and empty the second list.

[0132] It should be understood that FIG. 5D is for illustrative purposes only and is not intended to be limiting.

[0133] For clarity, an example procedure can be described as follows: 2> Else, if reportType is set to eventTriggered and the exit conditions applicable to this event are met for one or more cells included in the cellsTriggeredList defined in VarMeasReportList for this measId and for all measurements after layer 3 filtering taken during the timeToTrigger defined in VarMeasConfig for this event: 3>Delete the relevant cells in the cellsTriggeredList defined in the VarMeasReportList for this measId; 3>If reportOnLeave is set to true and triggerThreshold is not set for the corresponding reporting configuration: 4>Initiate the measurement reporting procedure specified in 5.5.5; 3>If reportOnLeave is set to true and triggerThreshold is set for the corresponding reporting configuration: 4>Include the relevant cell in the cellsLeavingList of this measId; 4> If triggerValue (the sum of triggerWeight of all cells in cellsLeavingList) is greater than or equal to triggerThreshold 5>Initiate measurement reporting procedure; 5>Set the triggerValue for this measId to 0 (or remove the cell in cellsLeavingList). <Embodiment 8>

[0134] In this embodiment, the trigger conditions are related to the end of the cell and the quality of the cell.

[0135] In some embodiments, if the second cell satisfies the termination condition, terminal device 110 may determine that the trigger condition is met if the quality of the second cell is worse than the quality of other cells (e.g., the worst cell) in the second list.

[0136] In some embodiments, if the number of cells in the second list to which the second cell is added is less than a predetermined number and the quality of the second cell is worse than the quality of the other cells in the second list (e.g., the worst cell), the terminal device 110 may determine that the trigger condition is met. <Example of a report based on beam measurements>

[0137] 6 is a schematic diagram illustrating another process 600 of communication for measurement reporting according to an embodiment of the present disclosure. For clarity, the process 600 will be described with reference to FIG. 1. The process 600 may include the terminal device 110 and the network device 120 as shown in FIG. 1.

[0138] 6, the network device 120 transmits (610) a measurement configuration to the terminal device 110. In some embodiments, the measurement configuration may indicate a starting condition associated with a beam measurement (also referred to herein as a fifth condition for convenience) and a corresponding trigger condition for a measurement report (also referred to herein as a sixth condition for convenience). In some embodiments, the measurement configuration may also indicate a starting condition associated with a cell measurement (also referred to herein as a seventh condition for convenience). It should be understood that the measurement configuration may also include any other suitable information.

[0139] Based on the measurement configuration, the terminal device 110 can perform beam measurements. Referring to Figure 6, if the measurement value of the beam of a cell (for convenience, also referred to as the third cell herein) satisfies a fifth condition, the terminal device 110 can include (620) the beam in a list (for convenience, also referred to as the third list herein). Note that the present application is not limited to the fifth condition, and any suitable condition can be realized.

[0140] Continuing with reference to FIG. 6, if the third list satisfies a sixth condition (i.e., a trigger condition), the terminal device 110 may transmit a measurement report (630). For clarity, some exemplary embodiments will be described in relation to embodiments 9 to 11. <Embodiment 9>

[0141] In this embodiment, the trigger condition is related to the number of beams in the cell.

[0142] In some embodiments, if the number of beams of the third cell in the third list is greater than or equal to a predetermined number (for convenience, also referred to herein as the third predetermined number), the terminal device 110 can determine that the third list meets the trigger condition.

[0143] For example, an example procedure for a beam-based measurement event can be described as follows. UE: 1> The conditions for starting this event are considered to be met if the condition A4-1' specified below is met; 1> If the condition A4-2' specified below is met, the completion condition of this event will be deemed to be met. Inequality A4-1' (starting condition) Mn + offset value - Hys>Thresh Inequality A4-2' (termination condition) Mn + offset value + Hys <Thresh The variables in the formula are defined as follows: Mn is the beam measurement result derived based on the SS / PBCH blocks or CSI-RS of the neighboring cell without taking the offset into account (or if reportType is set to eventBeamTriggered, Mn is the beam measurement result derived based on the SS / PBCH blocks or CSI-RS of the neighboring cell). An offset value is the sum of other offset values. Hys is the hysteresis parameter for this event (i.e., the hysteresis defined in reportConfigNR for this event). Thresh is the threshold parameter for this event; 2>If reportType is set to eventTriggered (i.e. eventBeamTriggered) and the corresponding reportConfig contains numberOfTriggeringBeams and the entry condition applicable to this event (i.e. the event corresponding to the eventId of the corresponding reportConfig in VarMeasConfig) is met for one or more beams of the applicable cell for all measurements after Layer 3 filtering performed during the timeToTrigger defined for this event in VarMeasConfig: 3>If VarMeasReportList does not contain a measurement report entry for this measId: 4>Include a measurement report entry in VarMeasReportList for this measId; 3> If the relevant cell is not included in cellsTriggeredList 4>Include the cells involved in the cellsTriggeredList defined in the VarMeasReportList for this measId; 3>If the number of beams in beamsTriggeredList is greater than or equal to numberOfTriggeringBeams: 4>Include the involved beams in the beamsTriggeredList of the corresponding cell; 3> Otherwise: 4>Include the involved beams in the beamsTriggeredList of the corresponding cell; 5>If the number of beams in beamsTriggeredList is greater than or equal to numberOfTriggeringBeams: 6>Set numberOfReportsSent defined in VarMeasReportList for this measId to 0; 6>Initiate measurement reporting procedure. <Embodiment 10>

[0144] In this embodiment, the trigger condition is associated with the number of beams in the third list, which may belong to different cells.

[0145] In some embodiments, if the number of beams in the third list is greater than or equal to a predetermined number (for convenience, also referred to herein as a fourth predetermined number), the terminal device 110 can determine that the third list meets the trigger condition.

[0146] In some embodiments, once the measurement report is transmitted, the terminal device 110 may reset the number of beams in the third list.

[0147] For example, an example procedure can be described as follows: 2>If reportType is set to eventTriggered (i.e. eventBeamTriggered) and the corresponding reportConfig contains sumNumberOfTriggeringBeams and the entry condition applicable to this event (i.e. the event corresponding to the eventId of the corresponding reportConfig in VarMeasConfig) is met for one or more beams of the applicable cell for all measurements after Layer 3 filtering performed during the timeToTrigger defined for this event in VarMeasConfig: 3>If VarMeasReportList does not contain a measurement report entry for this measId (first cell triggers the event): 4>Include a measurement report entry in VarMeasReportList for this measId; 3> If the relevant cell is not included in cellsTriggeredList 4>Include the cells involved in the cellsTriggeredList defined in the VarMeasReportList for this measId; 3>If numberOfBeams is greater than or equal to sumNumberOfTriggeringBeams 3> Increment triggeringBeamsCount by the number of beams that met the entry conditions applicable to this event 3> Otherwise 4> Increment triggeringBeamsCount by the number of beams that met the entry conditions applicable to this event 3>If numberOfBeams is greater than or equal to sumNumberOfTriggeringBeams 4> Initiate measurement reporting procedure. <Embodiment 11>

[0148] In some embodiments, if the measurement value of the third cell satisfies the trigger condition (i.e., the seventh condition), the terminal device 110 can include the third cell in a list (also referred to herein as the fourth list for convenience). If the number of cells in the fourth list is less than a predetermined number (also referred to herein as the fifth predetermined number for convenience) and the number of beams in the third list is equal to or greater than the fourth predetermined number, the terminal device 110 can determine that the third list satisfies the trigger condition and can start measurement reporting.

[0149] 7 is a schematic diagram illustrating an example process 700 for beam measurement-based measurement reporting in accordance with some embodiments of the present disclosure. As shown in FIG. 7, in step 710, the terminal device 110 may determine that the cell satisfies a start condition for event X.

[0150] In step 711, terminal device 110 may determine whether the number of cells in the fourth list to which the third cell has not been added is greater than or equal to a predetermined number (e.g., numberOfTriggeringCells). If the number of cells in the fourth list to which the third cell has not been added is less than the predetermined number, process 700 may proceed to step 712. In step 712, terminal device 110 may add the third cell to the fourth list.

[0151] In step 713, terminal device 110 may determine whether the number of cells in the fourth list to which the third cell was added is greater than or equal to a predetermined number. If the number of cells in the fourth list to which the third cell was added is less than the predetermined number, process 700 may proceed to step 714.

[0152] At step 714, the terminal device 110 may determine whether the number of beams in the third list (e.g., triggeringBeamsCount) is greater than or equal to a predetermined number (e.g., numberOfTriggeringBeams). If the number of beams in the third list is greater than or equal to the predetermined number, process 700 may proceed to step 715. At step 715, the terminal device 110 may increment the number of beams in the third list. It should be understood that the beams in the third list may belong to different cells.

[0153] Returning to step 714, if the number of beams in the third list is less than the predetermined number, process 700 may proceed to step 716. In step 716, terminal device 110 may increment the number of beams in the third list. In step 717, terminal device 110 may determine whether the number of beams in the third list is greater than or equal to the predetermined number. If the number of beams in the third list is greater than or equal to the predetermined number, in step 718, terminal device 110 may initiate measurement reporting.

[0154] Returning to step 713, if the number of cells in the fourth list to which the third cell was added is greater than or equal to the predetermined number, process 700 may proceed to step 719. In step 719, terminal device 110 may initiate measurement reporting.

[0155] Returning to step 711, if the number of cells in the fourth list to which the third cell has not been added is greater than or equal to the predetermined number, process 700 may proceed to step 720. At step 720, terminal device 110 may add the third cell to the fourth list.

[0156] It should be understood that FIG. 7 is for illustrative purposes only and is not intended to be limiting.

[0157] For clarity, an example procedure can be described as follows: 2>If reportType is set to eventTriggered (i.e. eventBeamTriggered) and the corresponding reportConfig contains numberOfTriggeringBeams and the entry condition applicable to this event (i.e. the event corresponding to the eventId of the corresponding reportConfig in VarMeasConfig) is met for one or more beams of the applicable cell for all measurements after Layer 3 filtering performed during the timeToTrigger defined for this event in VarMeasConfig: 3>If VarMeasReportList does not contain a measurement report entry for this measId (first cell triggers the event): 4>Include a measurement report entry in VarMeasReportList for this measId; 3>If the number of cells in cellsTriggeredList is greater than or equal to numberOfTriggeringCells: 4> If the relevant cell is not included in cellsTriggeredList 5>Include cells involved in the cellsTriggeredList defined in the VarMeasReportList for this measId; 3> Otherwise 4> If the involved cell is not included in cellsTriggeredList: 5>Include cells involved in the cellsTriggeredList defined in the VarMeasReportList for this measId; 4>If the number of cells in cellsTriggeredList is greater than or equal to numberOfTriggeringCells: 5> 5>Initiate the measurement reporting procedure specified in 5.5.5 4> Otherwise: 5>If numberOfBeams is greater than or equal to sumNumberOfTriggeringBeams 6> Increment triggeringBeamsCount by the number of beams that met the entry criteria applicable to this event 5> Otherwise 6> Increment triggeringBeamsCount by the number of beams that met the entry criteria applicable to this event 6>If numberOfBeams is greater than or equal to sumNumberOfTriggeringBeams 7> 7>Initiate measurement reporting procedure. <Example of adaptation of start conditions>

For clarity, the process 800 will be described with reference to FIG. 1. The process 800 may include the terminal device 110 and the network device 120, as shown in FIG. 1.

[0159] As shown in FIG. 8, network device 120 transmits 810 a measurement configuration to terminal device 110. In some embodiments, the measurement configuration may include a height-related offset (referred to herein as heightSpecificOffset). The height-related offset may be applied in a starting condition if the height of terminal device 110 is equal to or greater than a predetermined height. In some embodiments, the measurement configuration may include a beam-related offset (referred to herein as numberOfBeamsOffset). The beam-related offset may be applied in a starting condition if the number of beams in the cell that meet a predetermined quality condition is equal to or greater than a threshold number. It should be understood that the measurement configuration may also include any other suitable information.

[0160] In some embodiments, the initiation condition for a measurement event is evaluated based on beam measurements. If N beams satisfy the initiation condition for this event, terminal device 110 can add the corresponding cell to cellsTriggeredList2. In some embodiments, terminal device 110 can initiate measurement reporting if the number of cells in cellsTriggeredList2 other than the corresponding cell is less than or equal to numberOfTriggeringCells and the number of cells in cellsTriggeredList2 that includes the corresponding cell is greater than or equal to numberOfTriggeringCells.

[0161] In some embodiments, the starting condition is evaluated based on beam measurements. If N beams meet the starting condition for this event, and these beams are from N cells based on cell IDs (i.e., physical cell IDs (PCIs)), where N is greater than or equal to a threshold, terminal device 110 can start measurement reporting. Referring to FIG. 8, terminal device 110 can determine (820) a starting condition (also referred to herein as the eighth condition for convenience) based on at least one of beam measurements or the height of terminal device 110.

[0162] In some embodiments, if the height of terminal device 110 is equal to or greater than a predetermined height, terminal device 110 can determine an eighth condition based on a height-related offset.

[0163] In some embodiments, if the measurement report is triggered by a height event, the terminal device 110 can set aerialStatus according to the triggered height event and make an eighth condition determination based on the height-related offset associated with aerialStatus. For example, when event H1 starts, the terminal device 110 can set aerialStatus to 1. When event H2 starts, the terminal device 110 can set aerialStatus to 2. When event H1 or event H2 ends, the terminal device 110 can set aerialStatus to 0. For aerialStatus 0, 1, and 2, the corresponding height-related offsets for the measurement event can be heightSpecificOffset0, heightSpecificOffset1, and heightSpecificOffset2.

[0164] For example, an example procedure can be described as follows: 2>If triggerType is set to event, eventId is set to eventH1 or eventH2, and the start condition applicable to this event (i.e. the event corresponding to the eventId in the corresponding reportConfig in VarMeasConfig) is met during the timeToTrigger defined in the VarMeasConfig of this event, and VarMeasReportList does not contain a measurement report entry for this measId: 3>Include a measurement report entry in VarMeasReportList for this measId; 3>Set numberOfReportsSent defined in VarMeasReportList for this measId to 0; 3> Set aerialStatus to 1 for eventH1 and 2 for eventH2 3> Initiate the measurement reporting procedure.

[0165] For example, exemplary event A4 can be described as follows: UE: 1> The conditions for starting this event are considered to be met if the condition A4-1 set out below is met; 1> If the condition A4-2 specified below is met, the completion condition of this event will be deemed to be met. Inequality A4-1 (starting condition) Mn+offset value+heightSpecificOffset-Hys>Thresh Inequality A4-2 (termination condition) Mn+offset value+heightSpecificOffset+Hys <Thresh The variables in the formula are defined as follows: Mn is the measurement result of the neighboring cell without taking into account the offset. An offset value is the sum of other offset values. heightSpecificOffset is the height-specific offset for this event (i.e. depending on the aerialStatus, consider the corresponding offset in the reportConfigNR for this event) Hys is the hysteresis parameter for this event (i.e., the hysteresis defined in reportConfigNR for this event). Thresh is the threshold parameter for this event.

[0166] In some embodiments, if the number of beams in a cell that meet a predetermined quality condition is equal to or greater than a threshold number (for convenience, also referred to herein as a second threshold number), the terminal device 110 can determine an eighth condition based on beam-related offsets.

[0167] For example, exemplary event A4 can be described as follows: UE: 1> The conditions for starting this event are considered to be met if the condition A4-1 set out below is met; 1> If the condition A4-2 specified below is met, the completion condition of this event will be deemed to be met. Inequality A4-1 (starting condition) Mn+offset value+numberOfBeamsOffset-Hys>Thresh Inequality A4-2 (termination condition) Mn+offset value+numberOfBeamsOffset+Hys <Thresh The variables in the formula are defined as follows: Mn is the measurement result of the neighboring cell without taking into account the offset. An offset value is the sum of other offset values. numberOfBeamsOffset is the offset to be considered if the number of beams with beam metric values ​​exceeding absThreshSS-BlocksConsolidation is equal to or greater than the threshold. Hys is the hysteresis parameter for this event (i.e., the hysteresis defined in reportConfigNR for this event). Thresh is the threshold parameter for this event.

[0168] Continuing with reference to FIG. 8, if the measurement value of a cell (also referred to herein as the fourth cell for convenience) satisfies the eighth condition, the terminal device 110 may include (830) the fourth cell in a list (also referred to herein as the fifth list for convenience) to trigger a measurement report.

[0169] In some embodiments, if the number of beams in the fourth cell that satisfy the eighth condition is greater than or equal to a threshold number (for convenience, also referred to herein as the first threshold number), the terminal device 110 can determine that the measurement values ​​of the fourth cell satisfy the eighth condition.

[0170] This method also avoids frequent measurement reporting.

[0171] It should be understood that the solutions of the above embodiments 1 to 11 can be implemented separately or in any suitable combination. <Example of the method>

It should be understood that method 1100 may include additional blocks not shown and / or some blocks shown may be omitted, and that the scope of the present disclosure is not limited in this regard.

[0201] In block 1110, the terminal device 110 determines whether the measurement values ​​of the beam of the third cell satisfy a fifth condition. If the measurement values ​​of the beam of the third cell satisfy the fifth condition, the method 1100 proceeds to block 1120.
