However, if configured simultaneously, some parameters may conflict. This issue requires further investigation. Summary of the Invention

[0044] In wireless communication systems, adapting airborne UEs (e.g., UAV UEs) to existing systems has been studied. A key characteristic of airborne UEs is that after they take off, they experience very low line-of-sight path loss with neighboring cells. In this situation, the airborne UE can not only receive strong signals from many neighboring cells but also cause significant interference to them. To detect this, the network (NW) is configured to measure the airborne UE and determine the situation based on measurement results reported from the airborne UE. New event triggers H1 / H2 are introduced to trigger measurement reports when the UAV UE's flight altitude is above or below a threshold.

[0045] In NR, it has been agreed to introduce a height-dependent measurement feature, meaning that measurement-dependent parameters can be configured for each altitude range in a single configuration, and multiple values ​​associated with multiple altitude ranges can be configured simultaneously. This feature aims to reduce signaling overhead and latency for Radio Resource Control (RRC) reconfiguration based on UE altitude reports, and further reduce interference caused by the corresponding signaling. More specifically, in the Measurement Target (MO) configuration, parameters... ssb - to measure This parameter can be configured for each altitude range, controlling which synchronization signals and PBCH blocks (SSBs) the UE measures, rather than all SSBs. In the Measurement Reporting (MR) configuration, thresholds for events A3 / A4 / A5 can be configured for each altitude range, along with another parameter. number of triggering cells . number of triggering cells The purpose is for interference detection, and when such parameters are configured, a measurement report will be triggered after multiple cells meet the reporting conditions instead of just one cell, thereby avoiding overly frequent measurement reports and reducing signaling overhead and interference.

[0046] However, some issues need to be considered and studied. One issue is that when... ssb - to measure When configured, the UE only measures the configured SSB, while when number of triggering cells When configured, the UE may need to (as expected by the NW) measure all SSBs. Because ssb - to measure In the MO configuration, and number of triggering cells In MR configuration, these two parameters can therefore be configured together, even for the same or overlapping height ranges. When both are configured together, the UE can measure only... ssb - to measure This will cause inaccurate and interfering measurement results. It has been proposed that when... number of triggering cells When configured, ignore ssb - to measure That is, when number of triggering cells When configured, the UE always measures all SSBs to obtain accurate interference measurement results. However, this means that the configured SSBs... to measure It is not effective in all cases, therefore it cannot be utilized. ssb - to measure Its advantages include, for example, mobility optimization.

[0047] Another issue is that it is configured for ssb - to measure and number of triggering cells The height ranges may not be entirely identical; that is, there may be overlapping and non-overlapping height ranges. How should the UAV UE handle this situation? ssb - to measure and number of triggering cells The conflict in SSB measurements between them needs to be further investigated.

[0048] A solution is proposed to address the aforementioned problems. According to embodiments of this disclosure, the UE can receive two highly relevant parameters from a network entity: a first parameter indicating at least one SSB for measuring a first altitude range, and a second parameter indicating the number of cells used to trigger measurement reports for a second altitude range. The UE can conditionally ignore one of the two highly relevant parameters. Note that “ignoring” one of the two parameters also means “prioritizing” the other parameter. Therefore, the UE will follow the “prioritized” parameter and determine the “ignored” parameter as invalid. In this disclosure, the two phrases have the same or opposite meanings.

[0049] The first parameter is in the Measurement Target (MO) configuration. ssb - to measure And the second parameter is in the measurement report configuration. number of triggering cells In some embodiments, if a specific height range is targeted... ssb - to measure and number of triggering cells If both are configured, the UE can ignore them. number of triggering cells In some embodiments, whether to measure the configured ssb - to measure The (multiple) SSBs or all SSBs in the time range are used for interference configured by the time range. In some embodiments, whether the configured [interference] is measured... ssb - to measure The (multiple) or all SSBs in the configuration are used to interfere with the reported flight path. In some embodiments, whether the configured [SSBs] are measured... ssb - to measure The (multiple) or all SSBs in the parameter are used for interference indicated in RRC signaling or MAC / PHY signaling. In some embodiments, the UE may periodically prioritize numberoftriggeringcells and measure all SSBs, while at other times, the UE measures only the configured (multiple) SSBs. In some embodiments, the UE may ignore one of the parameters based on the number of observed cells.

[0050] Additionally, the UE can ignore one of the parameters for a specific altitude range. In some embodiments, for the altitude range associated with the ignored parameter, one of the parameters is ignored. In some embodiments, for ssb - to measure and number of triggering cells The overlapping height ranges between parameters are ignored. In some embodiments, for the affected height ranges of other parameters, one of the parameters is ignored.

[0051] The various aspects of this disclosure are described in the context of wireless communication systems. Figure 1Examples of wireless communication systems 100 that may be implemented in accordance with some embodiments of this disclosure are shown. Wireless communication system 100 may include one or more network entities 102 (also referred to as network devices (NEs)), one or more UEs 104, a core network 106, and a packet data network 108. Wireless communication system 100 may support various radio access technologies. In some implementations, wireless communication system 100 may be a 4G network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, wireless communication system 100 may be a 5G network, such as an NR network. In other implementations, wireless communication system 100 may be a combination of 4G and 5G networks, or other suitable radio access technologies, including IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20. Wireless communication system 100 may support radio access technologies beyond 5G. In addition, the wireless communication system 100 can support technologies such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA).

[0052] One or more network entities 102 may be distributed across a geographical area to form a wireless communication system 100. One or more network entities among the network entities 102 described herein may be, include, or may be referred to as network nodes, base stations, network elements, radio access networks (RANs), base transceiver stations, access points, NodeBs, eNodeBs (eNBs), next-generation NodeBs (gNBs), or other suitable terms. Network entities 102 and UE 104 may communicate via communication link 110, which may be a wireless or wired connection. For example, network entities 102 and UE 104 may perform wireless communication (e.g., receive signaling, send signaling) via a Uu interface. In a 3GPP non-terrestrial network (NTN), network entity 102 in satellite form may communicate directly with UE 104 using an NR / LTE Uu interface. This satellite may be a transparent satellite or a regenerated satellite. For an NTN with a transparent satellite, a terrestrial base station may communicate with the UE via the satellite. For an NTN with a regenerated satellite, the base station may be located on the satellite and communicate directly with the UE.

[0053] Network entity 102 can provide a geographic coverage area 112 for which it can support services (e.g., voice, video, packet data, messaging, broadcasting, etc.) for one or more UEs 104 within the geographic coverage area 112. For example, network entity 102 and UE 104 can support wireless communication of signals associated with services (e.g., voice, video, packet data, messaging, broadcasting, etc.) based on one or more radio access technologies. In some implementations, network entity 102 can be mobile, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but different geographic coverage areas 112 can be associated with different network entities 102. The information and signals described herein can be represented using a variety of different techniques and methods. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced in the description can be represented by voltage, current, electromagnetic waves, magnetic fields or particles, light fields or particles, or any combination thereof.

[0054] One or more UEs 104 may be distributed across a geographical area of ​​the wireless communication system 100. UE 104 may include or be referred to as a mobile device, wireless device, remote device, remote unit, handheld device, or subscriber device, or some other suitable term. In some implementations, UE 104 may be referred to as a unit, station, terminal, or client, among other examples. Alternatively or additionally, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a Machine Type Communication (MTC) device, among other examples. In some implementations, UE 104 may be stationary within the wireless communication system 100. In some other implementations, UE 104 may be mobile within the wireless communication system 100. In some other implementations, UE 104 may be a UAV UE and may communicate with one or more network entities 102 while in flight.

[0055] One or more UEs 104 can be devices of different forms or with different capabilities. Some examples of UEs 104 are shown in... Figure 1 It is shown in the middle. For example... Figure 1 As shown, UE 104 can communicate with various types of devices, such as network entity 102, other UE 104, or network devices (e.g., core network 106, packet data network 108, relay devices, integrated access and backhaul (IAB) nodes, or another network device). Alternatively or additionally, UE 104 can support communication with other network entities 102 or UE 104, which can act as relays in the wireless communication system 100.

[0056] UE 104 can also support direct wireless communication with other UE 104s via communication link 114. For example, UE 104 can support direct wireless communication with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, communication link 114 may be referred to as a side link. For example, UE 104 can support direct wireless communication with another UE 104 via a PC5 interface.

[0057] Network entity 102 may support communication with core network 106, or communication with another network entity 102, or both. For example, network entity 102 may interface with core network 106 via one or more backhaul links 116 (e.g., via S1, N2, N2, or another network interface). Network entities 102 may communicate with each other via backhaul links 116 (e.g., via X2, Xn, or another network interface). In some implementations, network entities 102 may communicate directly with each other (e.g., between network entities 102). In some other implementations, network entities 102 may communicate with each other or indirectly (e.g., via core network 106). In some implementations, one or more network entities 102 may include sub-components, such as access network entities, which may be an example of an access node controller (ANC). The ANC may communicate with one or more UEs 104 via one or more other access network transport entities, which may be referred to as wireless heads, smart wireless heads, or transmit-receive points (TRPs).

[0058] In some implementations, network entity 102 can be configured in a decomposed architecture that can utilize a protocol stack physically or logically distributed across two or more network entities 102, such as an Integrated Access Backhaul (IAB) network, an Open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a Virtualized RAN (vRAN) (e.g., a Cloud RAN (C-RAN)). For example, network entity 102 may include one or more of the following: a Central Unit (CU), a Distributed Unit (DU), a Radio Unit (RU), a RAN Intelligent Controller (RIC) (e.g., a Near-RT RIC, a Non-RT RIC), a Service Management and Orchestration (SMO) system, or any combination thereof.

[0059] An RU can also be referred to as a radio head, intelligent radio head, remote radio head (RRH), remote radio unit (RRU), or transmit-receive point (TRP). One or more components in network entity 102 within a decomposed RAN architecture can be co-located, or one or more components in network entity 102 can be located in different locations (e.g., separate physical locations). In some implementations, one or more network entities 102 in a decomposed RAN architecture can be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0060] The functional division among CU, DU, and RU can be flexible and can support different functions depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combination thereof) are performed at the CU, DU, or RU. For example, the functional division of the protocol stack can be adopted between the CU and DU, such that the CU can support one or more layers of the protocol stack, while the DU can support one or more different layers of the protocol stack. In some implementations, the CU can host upper-layer protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functions and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU can connect to one or more DUs or RUs, and one or more DUs or RUs can host lower-layer protocol layer functions and signaling, such as Layer 1 (L1) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC), Media Access Control (MAC) layer), and each can be at least partially controlled by the CU 160.

[0061] Alternatively, or alternatively, the functional division of the protocol stack can be adopted between DU and RU, such that DU can support one or more layers of the protocol stack, while RU can support one or more different layers of the protocol stack. DU can support one or more different cells (e.g., via one or more RUs). In some implementations, the functional division between CU and DU or between DU and RU can be within the protocol layer (e.g., some functions for the protocol layer can be performed by one of CU, DU, or RU, while other functions of the protocol layer are performed by a different one of CU, DU, or RU).

[0062] The CU can be further functionally divided into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU can connect to one or more DUs via mid-range communication links (e.g., F1, F1c, F1-u), while the DUs can connect to one or more RUs via front-end communication links (e.g., open front-end (FH) interfaces). In some implementations, the mid-range or front-end communication links can be implemented based on interfaces (e.g., channels) between layers of a protocol stack, supported by corresponding network entities 102 communicating via such communication links.

[0063] Core network 106 can support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. Core network 106 can be an evolved packet core (EPC) or a 5G core network (5GC), which may include control plane entities (e.g., Mobility Management Entity (MME), Access and Mobility Management Functions (AMF)) that manage access and mobility, and user plane entities (e.g., Serving Gateway (S-GW), Packet Data Network (PDN) Gateway (P-GW), or User Plane Functions (UPF)) that route or interconnect packets to external networks. In some implementations, control plane entities may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signaling bearers, etc.), for one or more UEs 104 served by one or more network entities 102 associated with core network 106.

[0064] Core network 106 can communicate with packet data network 108 via one or more backhaul links 116 (e.g., via S1, N2, N2, or another network interface). Packet data network 108 may include application server 118. In some implementations, one or more UEs 104 may communicate with application server 118. UE 104 may establish a session (e.g., Protocol Data Unit (PDU) session, etc.) with core network 106 via network entity 102. Core network 106 can use the established session (e.g., established PDU session) to route traffic (e.g., control information, data, etc.) between UE 104 and application server 118. PDU session may be an example of a logical connection between UE 104 and core network 106 (e.g., one or more network functions of core network 106).

[0065] In the wireless communication system 100, network entity 102 and UE 104 can use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communication). In some implementations, network entity 102 and UE 104 can support different resource structures. For example, network entity 102 and UE 104 can support different frame structures. In some implementations, such as in 4G, network entity 102 and UE 104 can support a single frame structure. In some other implementations, such as in 5G and other suitable wireless access technologies, network entity 102 and UE 104 can support various frame structures (i.e., multiple frame structures). Network entity 102 and UE 104 can support various frame structures based on one or more digital technologies.

[0066] One or more digital technologies may be supported in the wireless communication system 100, and the digital technologies may include subcarrier spacing and cyclic prefix. The first digital technology (e.g., μ =0) can be associated with the first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first digital technique (e.g., ...) associated with the first subcarrier spacing (e.g., 15 kHz) is... μ =0) can utilize one time slot per subframe. Second digital technologies (e.g., μ =1) can be associated with the second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. The third digital technology (e.g., μ =2) can be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth digital technology (e.g., μ =3) can be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth digital technology (e.g., μ =4) can be associated with the fifth subcarrier spacing (e.g., 240 kHz) and the normal cyclic prefix.

[0067] The time intervals of resources (e.g., communication resources) can be organized according to frames (also called radio frames). Each frame can have a duration, for example, 10 milliseconds (ms). In some implementations, each frame can include multiple subframes. For example, each frame can include 10 subframes, and each subframe can have a duration, for example, 1 ms. In some implementations, each frame can have the same duration. In some implementations, each subframe of a frame can have the same duration.

[0068] Alternatively or concurrently, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may include a certain number (e.g., quantity) of time slots. The number of time slots in each subframe may also depend on one or more digital technologies supported in the wireless communication system 100. For example, a first digital technology, a second digital technology, a third digital technology, a fourth digital technology, and a fifth digital technology (i.e., ...) associated with corresponding subcarrier intervals of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz. μ =0、 μ =1、 μ =2、 μ =3、 μ =4) One time slot per subframe, two time slots per subframe, four time slots per subframe, eight time slots per subframe, and 16 time slots per subframe can be used, respectively. Each time slot can include a certain number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of time slots in a subframe can depend on the digital technology. For a normal cyclic prefix, a time slot can include 14 symbols. For an extended cyclic prefix (e.g., for a 60 kHz subcarrier spacing), a time slot can include 12 symbols. The relationship between the number of symbols per time slot, the number of time slots per subframe, and the number of time slots per frame for both normal and extended cyclic prefixes can depend on the digital technology. It should be understood that for the first digital technology (e.g., quantity) associated with the first subcarrier spacing (e.g., 15 kHz), μ The reference of =0 can be used interchangeably between subframes and time slots.

[0069] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, frequency channels, etc., based on frequency or wavelength. For example, the wireless communication system 100 can support one or more operating frequency bands, such as frequency range names FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some implementations, network entity 102 and UE 104 can perform wireless communication on one or more operating frequency bands. In some implementations, FR1 can be used by network entity 102 and UE 104, as well as other devices or apparatuses, for cellular communication services (e.g., control information, data). In some implementations, FR2 can be used by network entity 102 and UE 104, as well as other devices or apparatuses, for short-range, high data rate capabilities.

[0070] FR1 can be associated with one or more digital technologies (e.g., at least three digital technologies). For example, FR1 can be associated with the following: a first digital technology (e.g., μ =0), which includes a 15 kHz subcarrier spacing; second digital technology (e.g., μ =1), which includes a 30 kHz subcarrier spacing; third digital technology (e.g., μ =2), which includes a subcarrier spacing of 60 kHz. FR2 can be associated with one or more digital technologies (e.g., at least two digital technologies). For example, FR2 can be associated with a third digital technology (e.g., μ =2), which includes a 60 kHz subcarrier spacing; and a fourth digital technology (e.g., μ =3), which includes a subcarrier spacing of 120 kHz.

[0071] Figure 2 Examples of process flows for conditionally ignoring one of a first height-related parameter and a second height-related parameter, according to some exemplary embodiments of this disclosure, are shown. Process flow 200 may involve a UE 201 and a network entity (e.g., a base station) 202. Process flow 200 may be applied to a reference... Figure 1 The wireless communication system 100, for example, UE 201 can be any of UE 104, and network entity 202 can be any of network entity 102. It should be understood that process flow 200 can be applied to other communication scenarios.

[0072] At 210, network entity 202 can send a first parameter and a second parameter to UE 201. The first parameter indicates at least one synchronization signal and PBCH block (SSB) for measurement for a first altitude range, and the second parameter indicates the number of cells for triggering measurement reporting for a second altitude range 215. Accordingly, at 220, UE 201 can receive the first parameter and the second parameter 215 from network entity 202.

[0073] In some implementations, the first parameter can be from the measurement target (MO) configuration. ssb - to measure And the second parameter can be from the measurement report configuration. number of trigghering cells In some embodiments, UE 201 may be a UAV (UAV) UE.

[0074] When the first parameter is active, UE 201 will only measure the SSB(s) indicated in the first parameter for the associated first altitude range. When the first parameter is not configured or active, the UE may measure all SSBs. When the second parameter is active, UE 201 will report the measurement results according to the second parameter. For example, the UE triggers a measurement report after multiple cells, as indicated by the second parameter, meet the measurement report triggering conditions (e.g., events A3 / A4 / A5). Conversely, if the second parameter is not configured or active, UE 201 may trigger a measurement report as soon as a cell meets the measurement report triggering conditions.

[0075] At 230, network entity 202 can send condition information 235 to UE 201. Correspondingly, at 240, UE 201 can receive condition information 235 from network entity 202. This condition information can instruct UE 201 when or under what event to ignore which of the first and second parameters. In other words, if both parameters are configured for a certain altitude, a UE at that altitude can ignore one of the two parameters and only consider the other parameter to be in effect. Figure 2 Although condition information 235 is shown in signaling separate from the first parameter and the second parameter 215, it should be understood that condition information 235 may be sent in the same signaling along with either the first parameter or the second parameter 215.

[0076] At position 250, UE 201 conditionally ignores one of the first and second parameters. UE 201 can determine which of the first and second parameters to ignore based on received conditional information. Alternatively, UE 201 can also determine to ignore a predefined parameter of the first and second parameters without conditional information. In some embodiments, if both the first and second parameters are configured, and the associated first and second height ranges overlap, UE 201 ignores the second parameter. For example, UE 201 can ignore the second parameter when it is located at a specific height within the overlapping range.

[0077] Condition information 235 may include a third parameter indicating that one of the first and second parameters is ignored within a time range. UE 201 may ignore one of the first and second parameters based on this time range. For example, the third parameter may indicate that during the immediate time range immediately after UE 201 begins flight (i.e., the ascent phase), UE 201 ignores the second parameter to improve mobility performance.

[0078] Condition information 235 may include a fourth parameter that indicates at least one waypoint in the path reported to the UE to ignore one of the first and second parameters. UE 201 may ignore one of the first and second parameters based on at least one waypoint. For example, the fourth parameter may indicate that UE 201 ignores one of the two parameters when the UE is traveling around a specific waypoint or between two waypoints.

[0079] Condition information 235 may include a fifth parameter associated with one of the first and second parameters. The fifth parameter may indicate which of the first and second parameters is ignored. The fifth parameter may be associated with an ignored parameter or a prioritized parameter. Therefore, UE 201 may, based on the fifth parameter, ignore or prioritize one of the indicated first and second parameters.

[0080] Condition information 235 may include a sixth parameter indicating the periodicity of ignoring one of the first and second parameters. UE 201 may ignore one of the first and second parameters based on this periodicity. For example, the sixth parameter may indicate the periodicity of ignoring the first parameter. UE 201 may periodically ignore the first parameter, causing it to measure all SSBs to suppress interference. By periodically measuring all SSBs, UE 201 may have a larger number of observed cells with corresponding measurement results than a threshold. If the number of observed cells is larger than the configured threshold, indicating strong inter-cell interference, UE 201 may further ignore the first parameter. In addition to the parameters mentioned above, other parameters may also be possible as condition information, such as the UE's horizontal / vertical velocity, a specific location, or a specific altitude range.

[0081] Given that the associated height ranges for the first and second parameters may be inconsistent (e.g., overlapping), a height range for one of the parameters that is ignored needs to be defined. In some embodiments, this height range may be an associated range for the ignored parameter. Alternatively, the height range may be the overlapping range of the first and second height ranges. Alternatively, the height range may be the union of the first and second height ranges.

[0082] refer to Figure 2At point 260, UE 210 measures (multiple) SSBs and reports the measurement results to network entity 202 based on the priority of the first and second parameters. If the first parameter is prioritized (and the second parameter is ignored), UE 210 measures only the configured (multiple) SSBs and triggers a report once a cell meets the measurement report triggering condition, thus improving mobility performance. On the other hand, if the second parameter is prioritized (and the first parameter is ignored), UE 201 measures all (multiple) SSBs to reduce inference and triggers a report only after multiple cells meet the measurement report triggering condition, thus effectively reducing measurement report signaling and inference.

[0083] Figure 3 A schematic diagram is shown illustrating an example of a second parameter being conditionally ignored according to some exemplary embodiments of this disclosure. For better understanding, Figure 3 Reference ssb - to measure As the first parameter and number of triggering cells It is described as the second parameter.

[0084] In some embodiments, the UAV UE can be configured simultaneously for each height. ssb - to measure and each height number of triggering cells In other words, for UAV UEs, the range of heights associated with different altitudes... ssb - to measure and number of triggering cells One or more values ​​are configured simultaneously.

Furthermore, the above configuration and ignoring only apply to specific height ranges.

[0087] Figure 4 A schematic diagram is shown illustrating an example of a first and second parameter based on a time range that is conditionally ignored according to some exemplary embodiments of this disclosure. For better understanding, Figure 4 Reference ssb - to measure As the first parameter and number of triggering cells It is described as the second parameter.

That is, for... ssb - to measure and number of triggering cells Each configuration value, in addition to the associated height range, also has an associated time range.

For a height range of 1, number of triggering cells#1 Configured. For height range 2, number of triggering cells#2 Configured. For the time range T1 corresponding to the rising phase of the UAV UE, number of triggering cells Ignored; and for the time range T2 after the UAV UE reaches a certain flight altitude, ssb - to measure Ignored. By prioritizing for time range T1 ssb - to measure Mobility performance is improved; and by prioritizing for time range T2 number of triggering cellsAll SSBs in the cell were measured, and inter-cell interference could be effectively reduced.

[0090] Figure 5 A schematic diagram is shown illustrating an example of a first and second parameter based on waypoints conditionally ignored according to some exemplary embodiments of this disclosure. For better understanding, Figure 5 Reference ssb - to measure As the first parameter and number of triggering cells It is described as the second parameter.

[0091] In some embodiments, when ssb - to measure and number of triggering cells When both are configured, number of triggering cells or ssb - to measure Ignored, the reported flight path contains multiple associated waypoints and timestamps. That is, for ssb - to measure and number of triggering cells Each configuration value, in addition to the associated altitude range, is configured with associated waypoints in the reported flight path and optionally with a timestamp.

[0092] exist Figure 5 In the case of height range 1, ssb - to measure#1 Configured. For height range 2, ssb - ? Configured. For a height range of 1, to measure#2 Configured. And for a height range of 2, number of triggering cells#1 Configured. On the other hand, UAV UE in number of triggering cells#2 The report includes flight path information, which includes Flight Path Info Report Information also includes Way Point and related way Point Location The network can be configured to ignore which parameter in `numberoftriggeringcells` and `ssb-tomeasure` is related to. timestamp The relationships between information.

For another example, it might be for... number of triggering cells and way Point Location #1 The path between them way Point Location #2 It was ignored.

[0093] In some embodiments, when ssb - to measure and ssb - to measure Both should be ignored when configured. number of triggering cells or number of triggering cells This can be explicitly indicated in RRC signaling or MAC / PHY signaling. That is, for each configuration...ssb - to measure and ssb - to measure number of triggering cells It should be noted that there seems to be an unclear part in the original text around "ssb - " and "ssb - " which is translated as "ssb - " in a rather ambiguous way as the original seems incomplete at those points. You may want to double - check the original text for accuracy. In addition to the associated height range, the value can also indicate, for example, which parameter is ignored via 1 bit. For example, for a height range of 1, ssb - to measure#1 Configured. For height range 2, ssb - to measure#2 Configured. For a height range of 1, number of triggering cells#1 Configured. And for a height range of 2, number of triggering cells#2 Configured. And for a height range of 1, 1 bit is set to "1" to indicate. ssb - to measure Ignored, while for a height range of 2, bit 1 is set to "0" to indicate... number of triggering cells It was ignored.

[0094] In some embodiments, when ssb - to measure and number of triggering cells When both are configured, the UAV UE can be ignored. ssb - to measure Or, in other words, periodically prioritizing those with a period configured by the network. number of triggering cells The starting point and offset used for periodic measurements can also be configured by the network. Alternatively, the starting point can also be defined, for example, after a successful handover. In this way, the UAV UE can periodically measure all SSBs and measure the configured SSBs during idle periods.

[0095] The UAV UE periodically measures all SSBs and identifies observed cells with corresponding measurement results (RSRP / RSRQ of the SSB) greater than a threshold. If the number of observed cells is greater than or less than a configured threshold, the UAV UE can choose to ignore or prioritize one of the two parameters. For example, if the number of observed cells is greater than 10, priority is given. number of triggering cells Otherwise, prioritize. ssb - to measure .

[0096] Figure 6 A schematic diagram illustrating an example of the height range associated with the first and second parameters is provided. For ease of understanding, Figure 6 Reference ssb - to measure As the first parameter and number of triggering cells It is described as the second parameter.

[0097] In some embodiments, the UAV UE can be configured with each height... ssb - to measure and each height number of triggering cells In other words, for UAV UEs, the range of heights associated with different altitudes... sb - to measure and number of triggering cells One or more values ​​are configured simultaneously. For example... Figure 6 As shown, it is configured for sb - to measure The height range is from A meters to C meters, and it is configured fornumber of triggering cells The altitude range is from B meters to D meters. There may be overlap between these two altitude ranges (i.e., from B meters to C meters).

[0098] if sb - to measure and number of triggering cells One of the parameters is ignored; in some embodiments, the UAV UE may ignore one of the parameters associated with the height range used for that ignored parameter. For example, in Figure 6 In the middle, if sb - to measure If ignored, sb - to measure The distance between A meters and C meters is ignored. Alternatively, the UAV UE can be ignored for... ssb - to measure and number of triggering cell One of the parameters in the overlapping height range between them. For example Figure 6 ,if ssb - to measure If ignored, ssb - to measure The values ​​between B meters and C meters are ignored. Alternatively, the UAV UE may ignore one of the parameters used for all affected height ranges for another parameter. For example, in the above figure, if ssb - to measure If ignored, ssb - to measure The distance between B meters and D meters is ignored; it is used for number of triggering cell The affected height range. Because there is no number of triggering cell It is configured for a height range from A meters to B meters, so it is actually used for ssb - to measure and number of triggering cell The union of two height ranges (i.e., from A meters to D meters). ssb - to measure It was ignored.

[0099] According to the reference Figures 2 to 6 In some of the embodiments discussed, one of the highly relevant parameters for SSB measurement collisions can be conditionally ignored at the UE. In this way, the performance of the wireless communication system can be improved according to the needs of a specific scenario.
