Description

Technical Field

[0001] This topic generally relates to wireless communications. Specifically, this topic relates to methods, apparatus, and systems for improving resource utilization and reducing interference during wireless communications of unmanned aerial vehicle (UAV) user equipment (UE). Background Technology

[0002] In recent years, global interest in UAV-based services has increased dramatically. Various drone operations, personal flight entertainment experiences, and cargo delivery are example use cases. These and other uses likely depend on enhanced remote control capabilities and data transmission, which are of interest to service providers / operators and drone manufacturers. The original New Radio (NR) design was not anticipated for use with UAVs and therefore suffers from various drawbacks, limitations, and disadvantages. Therefore, the innovative methods, devices, and systems described in this paper are needed.

[0003] More specifically, in the original New Radio (NR), Radio Resource Management (RRM) measurements, for measurements of the serving cell and neighboring cells, can be performed in Radio Resource Control (RRC) Connected mode; for idle measurements, in RRC Idle and RRC Inactive modes; and for cell selection and reselection, in RRC Idle and RRC Inactive modes. RRM measurements can be performed on reference signaling (e.g., synchronization signal block (SSB) or Channel State Information Reference Signal (CSI-RS)). The network can configure RRM measurements via system information (SI) or dedicated RRC messages. A typical RRM measurement configuration may include the frequency, the SSB to be measured, the number of reference signals used to derive the radio quality of the cell, and the SSB measurement timing configuration (SMTC); that is, the UE can perform SSB measurements within the configured SMTC.

[0022] Figure 1 A diagram of an example wireless communication system 100 is shown, which includes a plurality of communication nodes (or simply nodes) configured to communicate wirelessly with each other. Typically, a communication node includes at least one user equipment 102 and at least one wireless access node 104. Figure 1 The example wireless communication system 100 is shown as including two user equipments 102 (including a first user equipment 102 (1) and a second user equipment 102 (2)) and a wireless access node 104. However, various other examples of wireless communication system 100 may exist, including any combination of various combinations of one or more user equipments 102 and / or one or more wireless access nodes 104.

[0023] Typically, user equipment described herein (such as user equipment 102) may include a single electronic device or apparatus capable of wireless communication over a network, or multiple electronic devices or apparatuses (e.g., a network of multiple electronic devices or apparatuses). User equipment may include, or be otherwise referred to as, a user terminal, user terminal equipment, or user equipment (UE). Furthermore, user equipment may be, or includes, mobile devices (such as mobile phones, smartphones, smartwatches, tablets, laptops, vehicles, or other vessels (as a non-limiting example, those driven by a person, motor, or engine, such as automobiles, airplanes, trains, ships, or bicycles)) or fixed or stationary devices (as a non-limiting example, such as desktop computers, or other computing devices that are typically stationary for extended periods (such as appliances, other relatively heavy devices including those for the Internet of Things (IoT), or computing devices used in commercial or industrial environments)). In various embodiments, user equipment 102 may include transceiver circuitry 106 coupled to antenna 108 to enable wireless communication with wireless access node 104. Transceiver circuitry 106 may also be coupled to processor 110, which may also be coupled to memory 112 or other storage devices. The memory 112 may store instructions or code therein, which, when read and executed by the processor 110, cause the processor 110 to implement the various methods described herein.

[0024] Furthermore, wireless access nodes as described herein (such as wireless access node 104) typically include a single electronic device or apparatus, or multiple electronic devices or apparatuses (e.g., a network of multiple electronic devices or apparatuses), and may include one or more base stations or other wireless network access points capable of wirelessly communicating with one or more user equipments and / or with one or more other wireless access nodes 104 via a network. For example, in various embodiments, wireless access node 104 may include a 4G LTE base station, a 5G NR base station, a 5G centralized unit base station, a 5G distributed unit base station, a next-generation Node B (gNB), an enhanced Node B (eNB), or other similar or next-generation (e.g., 6G) base station. Wireless access node 104 may include transceiver circuitry 114 coupled to an antenna 116 (antenna 116 may include an antenna tower 118 in various ways) to enable wireless communication with user equipment 102 or another wireless access node 104. Transceiver circuitry 114 may also be coupled to one or more processors 120, which may also be coupled to memory 122 or other storage devices. The memory 122 may store instructions or code therein that, when read and executed by the processor 120, cause the processor 120 to implement one or more of the methods described herein.

[0025] In various embodiments, two communication nodes in wireless system 100—such as user equipment 102 and wireless access node 104, two user equipment 102 without wireless access node 104, or two wireless access nodes 104 without user equipment 102—can be configured to wirelessly communicate with each other in or through a mobile network and / or wireless access network according to one or more standards and / or specifications. Typically, standards and / or specifications can define rules or procedures under which communication nodes can wirelessly communicate, and these rules or procedures in various embodiments may include those for communication in the millimeter (mm) band, and / or those with multiple antenna schemes and beamforming capabilities. Additionally or alternatively, the standards and / or specifications are those that define wireless access technologies and / or cellular technologies (such as, as a non-limiting example, Fourth Generation (4G) Long Term Evolution (LTE), Fifth Generation (5G) New Radio (NR), or New Radio Unlicensed (NR-U)).

[0026] Furthermore, in the wireless system 100, communication nodes are configured to wirelessly communicate with each other. Typically, communication between two communication nodes in the wireless system 100 can be or includes transmitting or receiving, and is usually simultaneous, depending on the perspective of the specific node in the communication. For example, for a given communication between a first node and a second node, where the first node transmits a signal to the second node and the second node receives a signal from the first node, the first node can be referred to as a source or transmitting node or device, and the second node can be referred to as a destination or receiving node or device, and the communication can be considered as the transmission of the first node and the reception of the second node. Of course, since each communication node in the wireless system 100 can both transmit and receive signals, a single communication node can be both a transmitting / source node and a receiving / destination node simultaneously, or switch between source / transmitting node and destination / receiving node.

[0027] Furthermore, specific signals can be characterized or defined as uplink (UL) signals, downlink (DL) signals, or sidelink (SL) signals. An uplink signal is a signal transmitted from user equipment 102 to radio access node 104. A downlink signal is a signal transmitted from radio access node 104 to user equipment 102. A sidelink signal is a signal transmitted from one user equipment 102 to another user equipment 102, or from one radio access node 104 to another radio access node 104. Moreover, for sidelink transmission, the first / source user equipment 102 transmits the sidelink signal directly to the second / destination user equipment 102 without forwarding it to radio access node 104.

[0028] Furthermore, the signals transmitted between communication nodes in system 100 can be characterized or defined as data signals or control signals. Typically, data signals are signals that include or carry data (such as multimedia data, e.g., voice and / or image data), while control signals are signals that carry control information that configures the communication nodes to communicate with each other in a specific way, or otherwise controls how the communication nodes transmit data signals to each other. Additionally, specific signals can be defined or characterized by combinations of data / control and uplink / downlink / sidelink signals, including uplink control signals, uplink data signals, downlink control signals, downlink data signals, sidelink control signals, and sidelink data signals.

[0029] For at least some specifications (such as 5G NR), data signals and control signals are transmitted and / or carried on physical channels. Typically, a physical channel corresponds to a set of time-frequency resources used for signal transmission. Different types of physical channels can be used to transmit different types of signals. For example, physical data channels (or simply data channels) are used to transmit data signals, and physical control channels (or simply control channels) are used to transmit control signals. Example types of physical data channels include, but are not limited to, physical downlink shared channels (PDSCH) for transmitting downlink data signals, physical uplink shared channels (PUSCH) for transmitting uplink data signals, and physical sidelink shared channels (PSSCH) for transmitting sidelink data signals. Furthermore, example types of physical control channels include, but are not limited to, physical downlink control channels (PDCCH) used for communicating downlink control signals, physical uplink control channels (PUCCH) used for transmitting uplink control signals, and physical sidelink control channels (PSCCH) used for transmitting sidelink control signals. As used herein, for simplicity, unless otherwise stated, a specific type of physical channel is also used to refer to the signals transmitted on that specific type of physical channel, and / or the transmission on that specific type of transmission. By way of example, PDSCH refers to the physical downlink shared channel itself, downlink data signals transmitted on the PDSCH, or downlink data transmission. Therefore, a communication node sending or receiving a PDSCH means that the communication node is sending or receiving signals on the PDSCH.

[0030] Additionally, for at least some specifications such as 5G NR and / or for at least some types of control signals, the control signals transmitted by the communication nodes may include control information necessary to enable the transmission of one or more data signals between the communication nodes and / or the scheduling of one or more data channels (or one or more transmissions on data channels). For example, such control information may include: information necessary to correctly receive, decode, and demodulate data signals received on a physical data channel during data transmission; and / or information necessary to grant uplink scheduling authorization, which informs the user equipment of the resources and transmission formats used for uplink data transmission. In some embodiments, the control information includes downlink control information (DCI) transmitted from the radio access node 104 to the user equipment 102 in the downlink direction. In other embodiments, the control information includes uplink control information (UCI) or sidelink control information (SCI), the uplink control information being sent from user equipment 102 to radio access node 104 in the uplink direction, and the sidelink control information being sent from one user equipment 102 (1) to another user equipment 102 (2) in the sidelink direction.

[0031] Furthermore, in the wireless communication system 100, the time slot format of multiple time slots or frames can be configured by the wireless access node 104 or specified by a protocol. In some examples, time slots can be indicated or designated as downlink time slots, flexible time slots, or uplink time slots. Similarly, in various embodiments, orthogonal frequency divisional multiplexing (OFDM) symbols can be indicated or designated as downlink symbols, flexible symbols, or uplink symbols.

[0032] Figure 2 An example of base station 200 is shown. Example base station 200 may include transceiver (Tx / Rx) circuitry 208 for transmitting / receiving communication with a UE and / or other base stations. Base station 200 may also include network interface circuitry 209 for enabling the base station to communicate with other base stations and / or the core network (e.g., via optical or wired interconnects, Ethernet, and / or other data transmission media / protocols). Base station 200 may optionally include input / output (I / O) interfaces 206 for communicating with operators, etc.

[0033] Base station 200 may also include system circuitry 204. System circuitry 204 may include processor 221 and / or memory 222. Memory 222 may include operating system 224, instructions 226, and parameters 228. Instructions 226 may be configured to cause one or more processors 124 to perform the functions of the base station. Parameters 228 may include parameters for supporting the execution of instructions 226. For example, parameters may include network protocol settings, bandwidth parameters, radio frequency mapping allocation, and / or other parameters.

[0034] As used herein, the term “network” (reference numeral 200) is interchangeable with gNB in ​​NR, eNB in ​​LTE, base station, core network, or radio access node of a wireless network.

[0035] Figure 3An example of an electronic device is shown for implementing terminal device 300 (e.g., user equipment (UE)). UE 300 may be a mobile device, such as a smartphone or a mobile communication module installed in a vehicle. UE 300 may include: a communication interface 302, system circuitry 304, input / output (I / O) interface 306, display circuitry 308, and storage device 309. Display circuitry 308 may include a user interface 310. System circuitry 304 may include any combination of hardware, software, firmware, or other logic / circuit. System circuitry 304 may be implemented, for example, through one or more system-on-a-chip (SoC), application-specific integrated circuit (ASIC), discrete analog and digital circuitry, and other circuitry. System circuitry 304 may be part of the implementation of any desired functionality in UE 300. In this regard, system circuitry 304 may include logic that facilitates, for example, decoding and playing music and video, such as MP3, MP4, MPEG, AVI, FLAC, AC3, or WAV decoding and playback; running applications; accepting user input; saving and retrieving application data; establishing, maintaining, and terminating cellular phone calls or data connections, such as internet connections; establishing, maintaining, and terminating wireless network connections, Bluetooth connections, or other connections; and displaying relevant information on user interface 310. User interface 310 and input / output (I / O) interface 306 may include a graphical user interface, a touch-sensitive display, haptic feedback or other haptic outputs, voice or facial recognition inputs, buttons, switches, speakers, and other user interface elements. Additional examples of I / O interface 306 may include a microphone, video and still image cameras, temperature sensors, vibration sensors, rotation and orientation sensors, headset and microphone input / output jacks, Universal Serial Bus (USB) connectors, memory card slots, radiation sensors (e.g., infrared (IR) sensors), and other types of inputs.

[0036] refer to Figure 3The communication interface 302 may include radio frequency (RF) transmit (Tx) and receive (Rx) circuitry 316, which processes the transmission and reception of signals via one or more antennas 314. The communication interface 302 may include one or more transceivers. This transceiver may be a wireless transceiver, including modulation / demodulation circuitry, a digital-to-analog converter (DAC), a shaping table, an analog-to-digital converter (ADC), filters, waveform shapers, preamplifiers, power amplifiers, and / or other logic for transmission and reception via one or more antennas or (for some devices) via a physical (e.g., wired) medium. The transmitted and received signals may follow any of the following formats, protocols, modulations (e.g., QPSK (Quadrature Phase Shift Keying), 16-QAM (Quadrature Amplitude Modulation), 64-QAM, or 256-QAM), frequency channels, bit rates, and encodings. As a specific example, communication interface 302 may include a transceiver supporting transmission and reception under the following standards: 2G, 3G, BT, WiFi, Universal Mobile Telecommunications System (UMTS), High Speed ​​Packet Access (HSPA)+, 4G / Long Term Evolution (LTE), and 5G standards. However, the techniques described below are applicable to other wireless communication technologies, regardless of whether these technologies originate from the 3rd Generation Partnership Project (3GPP), the GSM (Global System for Mobile Communications) Association, 3GPP2, the IEEE (Institute of Electrical and Electronics Engineers), or other partners or standards bodies.

[0037] refer to Figure 3The system circuitry 304 may include one or more processors 321 and a memory 322. The memory 322 stores, for example, an operating system 324, instructions 326, and parameters 328. The processor 321 is configured to execute instructions 326 to perform the desired functions of the UE 300. Parameters 328 can provide and specify configuration and operational options for instructions 326. The memory 322 may also store any BT, WiFi, 3G, 4G, 5G, or other data that the UE 300 will send or has received via the communication interface 302. In various implementations, the system power of the UE 300 may be provided by a power storage device (e.g., a battery or transformer).

[0038] Flight path information update In the LTE specification (3GPP TS 36.331) and related 3GPP discussion documents, the UAV UE 300 can report a planned flight path to the network or base station. This flight path may include a list of waypoints. Waypoints may include location information and / or timestamp information. Location information describes the planned location of the UAV UE 300 along the planned flight path. Timestamp information describes the expected or estimated time for the UAV UE 300 to arrive at the planned location.

[0039] refer to Figure 4 This illustrates the communication 400 between the UAV UE 300 and the base station (gNB) 200. For example... Figure 4 As shown, the UAV UE300 can generate or otherwise obtain an initial or updated flight path 401. An indication of the availability of this flight path 401 can be sent to the network 200 via a first RRC message in step S405. The first RRC message can be, for example, an RRC establishment complete message, an RRC reconfiguration complete message, an RRC recovery complete message, or a UE Assistance Information message.

[0040] In S410, network 200 can then request flight path information by sending a second RRC message. The second RRC message can be a UE Information Request message.

[0041] In S415, the UAV UE 300 can respond to the second RRC message by sending a third RRC message that includes flight path 401. The third RRC message can be a UE Information Response message.

[0042] According to conventional technology, UAV UE 300 will send a flight path availability indication to network 200 using a first RRC message in either of the following situations: (1) when UAV UE 300 has an initial flight path 401, UAV UE 300 indicates that flight path 401 is available by including an indicator, thereby triggering a flight path indication process; and (2) if UAV UE 300 has an updated flight path, UAV UE 300 indicates that the updated flight path 401 is available by including an indicator, thereby triggering a flight path update indication process. Network 200 configures an incremental (delta) time threshold and / or an incremental distance threshold. If the waypoint location changes beyond the configured incremental distance threshold, UAV UE 300 triggers a flight path update indication. If the waypoint timestamp changes beyond the configured incremental time threshold, UAV UE 300 triggers a flight path update indication process.

[0043] Continuing with the conventional technique, when UAV UE 300 passes a waypoint on a reported flight path, UAV UE 300 considers the passed waypoint obsolete and removes it from flight path 401 stored within UAV UE 300. UAV UE 300 then triggers a flight path update notification procedure by sending a first RRC message to network 200. The first RRC message indicates that flight path 401 has been updated, or that the updated flight path 401 is available to network 200. However, network 200 cannot distinguish the reason for triggering the flight path update notification and requests an updated flight path 401 by sending a second RRC message to UAV UE 300. If flight path 401 is updated simply because UAV UE 300 passed a waypoint, this update may be useless to network 200, especially when the passed waypoint includes a timestamp. Unnecessary updates to flight path 401 and associated acquisition processes waste radio resources and cause unnecessary interference to airborne UEs in flight and other base stations 200 on the ground.

[0044] Therefore, the technical solutions of this topic will now be described to address these problems in conventional techniques. Specifically, a waypoint can be considered outdated if the UAV UE 300 has already flown past a waypoint, or if the associated timestamp of the waypoint has expired. The flight path update notification process according to this topic may include: sending a first RRC message to network 200 to indicate that flight path 401 is available or that an update to flight path 401 is available.

[0045] The UAV UE 300 can internally determine whether a waypoint is outdated, and when a waypoint is outdated, it can determine whether a flight path notification process can be triggered based on rules. In the example, the rule can specify whether the flight path update notification process is prohibited or not prohibited for one or more of the following reasons: (1) one or more waypoints are outdated, (2) one or more waypoints including timestamps are outdated, or (3) one or more waypoints without timestamps are outdated.

[0046] Alternatively or additionally, in another example, network 200 may be configured to allow or disallow triggering flight path update / availability notifications for outdated waypoints. Allowing or disallowing triggering flight path update / availability notifications may be based on one or more of the following reasons: (1) one or more waypoints are outdated, (2) one or more waypoints including timestamps are outdated, or (3) one or more waypoints without timestamps are outdated.

[0047] Network 200 can configure whether to allow triggering flight path update / availability notifications by including a first indicator in the System Information (SI) of the serving cell or in the RRC message sent from Network 200 to UAV UE300. The absence of the first indicator may mean that triggering flight path update / availability notifications is allowed or not allowed for the aforementioned reasons.

[0048] UAV UE 300 can determine whether to initiate a flight path update / availability notification process based on the presence or value of the first indicator.

[0049] Based on this example, network 200 can be configured to trigger a flight path update / availability notification when one or more waypoints become outdated. This approach provides flexibility to network 200, as it can determine whether to allow flight path update / availability notifications based on its own implementation.

[0050] Alternatively or additionally, in another example, the UAV UE 300 may indicate to the network 200 that flight path 401 has been updated or is available due to outdated waypoints, and the network 200 may determine whether to request flight path 401 based on this indication. The UAV UE 300 may indicate to the network 200 at least one of the following reasons for triggering a flight path update / availability notification: (1) one or more waypoints are outdated, (2) one or more waypoints including timestamps are outdated, or (3) one or more waypoints without timestamps are outdated. The UAV UE 300 may indicate these reasons by including a second indicator in the first RRC message of S405. This first RRC message may be a UE assistance information message, an RRC recovery completion message, or an RRC reconfiguration completion message. The network 200 may determine whether to request a flight path based on the presence or value of the second indicator.

[0051] Based on this example, UAV UE 300 can indicate to network 200 the reason for updating flight path 401. Network 200 can then determine whether to request an update to flight path 401 based on the indicated reason, which may provide network 200 with the opportunity to avoid requesting an update to flight path if the updated flight path is not useful to network 200.

[0052] Each description in the preceding examples may be combined or used independently as needed without departing from the scope of this topic. For example, a rule may be defined specifying that the flight path update / availability notification process is prohibited because one or more waypoints, including timestamps, have expired. In the system information (SI), network 200 may indicate that the flight path update / availability notification is allowed because one or more waypoints, excluding timestamps, have expired. UAV UE 300 may trigger the flight path update / availability notification by sending a first RRC message to network 200. The first RRC message may include an indicator indicating that the flight path update / availability notification was triggered because a waypoint, excluding timestamps, has expired. Network 200 may determine whether to request an updated flight path 401 based on the indicator included in the first RRC message from UAV UE 300. Using these techniques, radio resources can be utilized more efficiently while reducing radio interference during the acquisition of the updated flight path 401 by network 200.

[0053] Highly relevant measurement report configuration Figure 6A general overview 600 of the steps associated with configuring and transmitting measurement reports is shown. As previously described, in S601, multiple measurement IDs can be provided from network 200 to UAV UE 300. In S602, UAV UE 300 can determine whether the transmission of a measurement report to network 200 has been triggered based on the satisfaction of predetermined criteria. In S603, UAV UE 300 can transmit the measurement report to network 200 based on this determination.

[0054] In standard NR specifications, a UE 300 in RRC connected state can be configured with a list of measurement IDs (measIDs). Each measID is associated with a measurement object configuration and a measurement report configuration. The measurement object configuration includes information for SSB intra-frequency / inter-frequency measurements and / or CSI-RS intra-frequency / inter-frequency measurements. The measurement report configuration specifies the criteria used to trigger measurement report events. Measurement report events are based on cell measurement results, which can be derived from SS / PBCH (Synchronization Signal / Physical Broadcast Channel) blocks or CSI-RS. The measurement report configuration can be configured to be event-triggered or periodic.

[0055] Furthermore, according to standard NR specifications, when a measurement report is configured to be event-triggered, it is configured with an event type. The following describes some events and their associated descriptions: Event A3: The improvement in wireless signal quality of the neighboring cell compared to the PCell / PSCell (Primary Cell / Primary Secondary Cell) is greater than one offset.

[0056] Event A4: The improvement in the wireless signal quality of the neighboring cell is greater than the absolute threshold.

[0057] Event A5: The wireless signal quality of PCell / PSCell degrades more than absolute threshold 1, and the wireless signal quality of neighboring cells / SCells improves more than another absolute threshold 2.

[0058] Event H1: The UE altitude in the air is higher than the absolute threshold.

[0059] Event H2: The UE altitude in the air is below the absolute threshold.

[0060] Each event (e.g., events A3 through A5, event H1, event H2) is configured with entry and exit conditions. An event can be triggered if the measurement reporting configuration for a measID is event-triggered, and the entry condition for the associated event is met for all measurements taken within a predefined timer (i.e., time-to-trigger, TTT) configured for that event in one or more applicable cells; that is, UE 300 begins executing measurement reporting for that measID. For example, the entry condition for event A4 is that the signal quality improvement of a neighboring cell is greater than an absolute threshold. In another example, the entry condition for event H1 is that the UE's height is higher than an absolute threshold.

[0061] Further in line with the latest 3GPP developments, new measurement types have been introduced to enable combinations of highly relevant measurement report configurations and measurement report events. The new event types include traditional event A3, A4, or A5 thresholds, and one of event H1 or event H2 thresholds. A single TTT for each event has also been introduced.

[0062] Furthermore, based on the latest 3GPP developments, the newly introduced measurement report event type is defined as follows: Event A3H1: The improvement in wireless signal quality of the neighboring cell compared to the wireless signal quality of SpCell is greater than one offset, and the airborne UE altitude is higher than the threshold.

[0063] Event A3H2: The improvement in wireless signal quality of the neighboring cell compared to the wireless signal quality of SpCell is greater than one offset, and the airborne UE altitude is below the threshold.

[0064] Event A4H1: The improvement in the wireless signal quality of the neighboring cell is greater than threshold 1, and the airborne UE altitude is higher than threshold 2.

[0065] Event A4H2: The improvement in the wireless signal quality of the neighboring cell is greater than threshold 1, and the airborne UE altitude is lower than threshold 2.

[0066] Event A5H1: The radio signal quality of SpCell has degraded beyond threshold 1, the radio signal quality of neighboring cells has degraded beyond threshold 2, and the airborne UE altitude is above threshold 3.

[0067] Event A5H2: The radio signal quality of SpCell degrades more than threshold 1, and the radio signal quality of neighboring cells improves more than threshold 2, and the airborne UE altitude is below threshold 3.

[0068] The following code illustrates how the new event type, event A4H1, is defined. The new event A4H1 includes the event A4 threshold (a4-Threshold-r18) and the event H1 threshold (h1-Threshold-r18).

[0069]

[0070] The conditions for entering event A4H1 are: the improvement in signal quality of the neighboring cell is greater than threshold 1, which is based on the configured event A4 threshold (a4-Threshold-r18), and at the same time, the height of the UE is higher than threshold 2, which is associated with the configured event H1 threshold (h1-Threshold-r18).

[0071] The purpose of this new event type is to achieve a highly correlated measurement reporting configuration. According to this approach, the network configures different reporting configurations for different airborne UE altitudes. Traditional Ax event thresholds are correlated with altitude-based thresholds. This is beneficial for UAV UE use cases where the wireless environment varies significantly with altitude (i.e., elevation).

[0072] The problems with the aforementioned method based on the traditional NR specification are now described. Assume network 200 is configured with two measIDs, each associated with the same measurement object (e.g., MO-1), and each measID has a different measurement reporting configuration (e.g., MR-1 and MR-2 respectively). Therefore, it can be stated as follows: MeasID-1 {MO-1, MR-1} MeasID-2 { MO-1, MR-2}.

[0073] MR-1 and MR-2 are event-triggered types and are configured with event type eventA4H1.

[0074] MR-1 is configured with event 1 having A4-threshold 1 and H1-threshold 1.

[0075] MR-2 is configured with event 2 having A4-threshold 2 and H1-threshold 2.

[0076] Figure 5 The diagram shows a UAV UE 300 at an altitude (i.e., altitude) of 501 relative to H1-threshold 2 505 and H1-threshold 1 510, where H1-threshold 2 505 is greater than H1-threshold 1 510. Therefore, when the UAV UE 300 flies above altitude 501 where both H1-threshold 1 510 and H1-threshold 2 505 are met for entry, one of the following scenarios may occur: Case 1: Only the entry condition for event 1 is met.

[0077] Case 2: Only the entry condition for event 2 is met.

[0078] Case 3: The entry conditions for both Event 1 and Event 2 are met simultaneously.

[0079] In scenario 1, only the entry condition for event 1 is met, which necessarily means that A4-threshold 1 is met and A4-threshold 2 is not met. The question then arises as to whether UAV UE 300 should report the measurement results for measID-1. If these measurements are transmitted, network 200 could interpret them as meaning that UAV UE 300 is flying above H1-threshold 1 510 and below H1-threshold 2 505. Since network 200 is configured with measID-2, which applies when UAV UE 300 is flying above H1-threshold 2 505, it can be confusing whether UAV UE 300 should report for measID-1 in this scenario. This is problematic.

[0080] In scenario 3, UAV UE 300 will trigger measurement reports for both measID-1 and measID-2. In the legacy NR specification, when a measurement event is triggered, UAV UE 300 will transmit an RRC message to report the measurement result for the measID associated with that measurement event. This means that in scenario 3, UAV UE 300 could transmit two separate RRC messages for measID-1 and measID-2. This is problematic because transmitting a measurement report for measID-1 is unnecessary in this case. It is also problematic because when network 200 receives a measurement report for measID-1, network 200 will respond accordingly based on that report. However, this could be erroneous behavior because network 200 also configures another measID (i.e., measID-2), which is applied when UAV UE 300 is flying above H1-threshold 2505.

[0081] Therefore, the technical solution of this topic will now be described to address the problems in the technical solutions of the traditional NR specification.

[0082] In this embodiment, the first measurement ID and the second measurement ID are each associated with the same measurement object and the corresponding first measurement report configuration and second measurement report configuration, and the measurement report configuration specifies the signal quality conditions and altitude conditions for triggering the transmission of the first measurement report or the second measurement report to the base station.

[0083] Specifically, when the first event is configured with a first H1 threshold and the second event is configured with a second H1 threshold, the UAVUE 300 may make a first determination based on one or more of the following conditions: (1) the relationship between the first H1 threshold and the second H1 threshold; (2) whether the entry condition of the second event is met or applicable; and / or (3) the height of the UAVUE 300.

[0084] If the first event is configured with a first H2 threshold and the second event is configured with a second H2 threshold, the UAV UE300 may make a first determination based on one or more of the following conditions: (1) the relationship between the first H2 threshold and the second H2 threshold; (2) whether the entry condition of the second event is met or applicable; and / or (3) the height of the UAV UE300.

[0085] The first determination may allow one or more of the following: (1) a configuration associated with the first measID may be applied; (2) a measurement report may be sent for the first measID; (3) a first event may be triggered; and / or (4) when the entry condition applies to the first event, a measurement report entry may be included in the VarMeasReportList for the first measID.

[0086] Optional: If the first H1 threshold is greater than the second H1 threshold, and the height of the UAV UE 300 is higher than the value based on the second H1 threshold, or If the first H1 threshold is less than the second H1 threshold, and the entry condition for the second event is not met, or If the first H1 threshold is less than the second H1 threshold, and the height of the UAV UE 300 is greater than the value based on the first H1 threshold but less than the value based on the second H1 threshold, or If the first H2 threshold is less than the second H2 threshold, and the height of the UAV UE 300 is lower than the value based on the second H2 threshold, or If the first H2 threshold is greater than the second H2 threshold, and the entry condition for the second event is not met, or If the first H2 threshold is greater than the second H2 threshold, and the height of the UAV UE 300 is less than the value based on the first H2 threshold but greater than the value based on the second H2 threshold, Then, the UE determines that one or more of the following are allowed: (1) the configuration associated with the first measID can be applied; (2) the measurement report for the first measID can be transmitted to the network 200; (3) the first event can be triggered; (4) when the entry condition applies to the first event, the measurement report entry can be included in the VarMeasReportList for the first measID.

[0087] Alternatively, under one or more of the following conditions: The first H1 threshold is less than the second H1 threshold; The first H1 threshold is less than the second H1 threshold, and the entry condition for the second event is met or applicable; The first H1 threshold is less than the second H1 threshold, and the height of UAV UE 300 is higher than the value based on the second H1 threshold; The first H1 threshold is less than the second H1 threshold, and the height of UAV UE 300 is higher than the value based on the second H1 threshold, and the entry condition of the second event is met or applied; The first H2 threshold is greater than the second H2 threshold; The first H2 threshold is greater than the second H2 threshold, and the entry condition for the second event is met or applicable; The first H2 threshold is greater than the second H2 threshold, and the height of the UAV UE 300 is lower than the value based on the second H2 threshold; or The first H2 threshold is greater than the second H2 threshold, and the entry condition of the second event is met or applicable, and the height of UAVUE 300 is lower than the value based on the second H2 threshold; Then, UAV UE 300 determines one or more of the following: (1) the configuration associated with the first measID cannot be applied; (2) the measurement report for the first measID cannot be transmitted to the network 200; (3) the first event cannot be triggered; (4) when the entry condition applies to the first event, the measurement report entry cannot be included in the VarMeasReportList for the first measID.

[0088] Using these techniques, the UAV UE 300 can determine whether a measID is applicable, whether to report measurement results based on its current altitude, and / or whether there exists another configured measID associated with the same measurement object and sharing the same event type but with different H1 / H2 thresholds. Therefore, if both measIDs are satisfied, only one measurement report can be transmitted, avoiding confusion and potential incorrect responses from the network 200.

[0089] Alternatively or additionally, for events configured with both an Ax threshold and an H1 / H2 threshold, the UAV UE 300 may always include height information 501 in the measurement report message. When the UAV UE 300 is configured with a first measID: (1) the first measID may be associated with a first report configuration; (2) the first report configuration is set to be event-triggered; (3) the first event is configured with an Ax threshold and an H1 or H2 threshold; and (4) the Ax threshold may be an A3, A4, or A5 threshold.

[0090] In the RRC message used to report the measurement results for the first measID, the UAV UE 300 may include height information 501 (i.e., in S603). By default, height information is always included in the measurement results for the first measID, regardless of whether the network 200 configures the UAV UE 300 to include height information in the measurement report message. The height information is the current height (i.e., altitude) of the UAV UE 300, or the height at the time the first event is triggered.

[0091] Using the technical solutions disclosed in this subject matter, network 200 can always know the height of UAV UE 300 and can respond correctly based on height 501 and H1 / H2 thresholds associated with the reported measID and other measIDs. For example, if the current height of UAV UE 300 is greater than the H1 threshold associated with the reported measID, and another H1 threshold is configured for another measurement event, then network 200 can determine that the measurement report is not necessary.
