Description

Technical Field

[0001] The present disclosure relates to methods and apparatus for flight path reporting in a wireless communication system. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology that allows high-speed packet communications. Many solutions have been proposed for the LTE goal, including those aimed at reducing user and supplier costs, improving service quality, and expanding and improving coverage and system capacity. As upper layer requirements, 3GPP LTE requires reduced cost per bit, increased service availability, flexible use of frequency bands, simple structure, open interfaces, and appropriate power consumption of terminals.

[0003] The International Telecommunication Union (ITU) and 3GPP have begun work on developing requirements and specifications for New Radio (NR) systems. 3GPP must identify and develop the technical components required for successful standardization of new RATs that will meet both urgent market needs and longer-term requirements set forth by the ITU Radiocommunication Sector (ITU-R) International Mobile Telecommunications (IMT)-2020 process in a timely manner. In addition, NR should be able to use any spectrum band up to at least the 100 GHz range that can be used for wireless communications even in the more distant future.

[0004] The goal of NR is to be a single technology framework that addresses all use cases, requirements and deployment scenarios, including enhanced mobile broadband (eMBB), massive machine type communications (mMTC), ultra-reliable and low latency communications (URLLC), etc. NR should be inherently forward compatible. Summary of the invention

[0005] Technical issues

[0006] For airborne UEs, it can indicate that the flight path is available when performing handover or RRC connection related operations. The network can request flight path information, and the UE can respond with the flight path information. That is, the flight path information can be delivered to the network only when the network requests it. The network can use the flight path information to derive appropriate configurations (e.g., mobility configurations, beam-related configurations, and access control configurations). Even the flight path is an important factor in the network's determination of optimized UE configurations based on artificial intelligence / machine learning (AI / ML).

[0007] Currently, the UE indicates the availability of flight path information to the network only when the cell changes, including handovers. As a result, even if the flight path of the UE happens to be updated due to traffic conditions or weather conditions in the air, the update cannot be immediately reported to the network. This problem is more serious in cells with wide coverage, such as NTN. This is because a UE with high-speed mobility may change its position considerably within the same cell without handover and high-speed mobility, and does not trigger the reporting of updated flight path information (if any) within the cell.

[0008] Therefore, it is important to enable the UE to report updated flight path information to the network within the same cell.

[0009] One method is that the UE reports the flight path information whenever the flight path is updated. This method allows the network to identify the latest flight path. However, according to the traditional process, three steps are required to notify the flight path information: i) notify the updated flight path from the UE; ii) request the flight path information from the network; iii) send the flight path information from the UE. Unconditional reporting will cause downlink / uplink interference in the LOS environment and increase the signaling overhead. Even if the UE notifies all the flight path information without a network command in step i), that is, ii) and iii) are not necessary, this information may also be unnecessary from the network's perspective. On the other hand, there are locations where this information may be absolutely necessary.

[0010] Therefore, there is a need to study flight path reporting in wireless communication systems.

[0011] Technical Solution

[0012] In one aspect, a method performed by a wireless device in a wireless communication system is provided. The method includes the following steps: receiving a configuration for flight path information including a condition related to a specific location from a network; sending a first message including information about a first flight path to the network; determining whether the flight path of the wireless device is updated from the first flight path to a second flight path; based on (i) the current location of the wireless device satisfies the condition related to the specific location, and (ii) the flight path is updated, sending a second message including information about the second flight path to the network.

[0013] On the other hand, a device for implementing the above method is provided.

[0014] Beneficial Effects

[0015] The present disclosure has various benefits.

[0016] According to some embodiments of the present disclosure, a wireless device may efficiently send a flight path report of the wireless device.

[0017] For example, when the network receives the latest flight path information from the UE at the location where the UE's flight path information is actually needed, it can efficiently manage information for mobility configuration. In addition, this approach is more efficient in terms of signaling compared to notifying the network every time the flight path changes.

[0018] In other words, when the network receives the latest flight path information from the UE at a specific location where the UE's flight path data is needed, for example, the network can efficiently handle information for mobility configuration. In addition, this approach is more efficient in signaling than notifying the network every time the flight path changes.

[0019] For example, according to some embodiments of the present disclosure, updated flight path related information may be efficiently reported by using entry / exit conditions for a specific area.

[0020] According to some embodiments of the present disclosure, a wireless network system can provide an efficient solution for flight path reporting of wireless devices.

[0021] The advantageous effects that can be obtained by the specific embodiments of the present disclosure are not limited to the advantageous effects listed above. For example, there may be various technical effects that a person of ordinary skill in the relevant field can understand and / or derive from the present disclosure. Therefore, the specific effects of the present disclosure are not limited to those explicitly described herein, but may include various effects that can be understood or derived from the technical features of the present disclosure.

CDMA can be implemented by radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA can be implemented by radio technologies such as Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), or Enhanced Data Rates for GSM Evolution (EDGE). OFDMA can be implemented by radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE802.16 (WiMAX), IEEE 802.20, or Evolved UTRA (E-UTRA). UTRA is part of Universal Mobile Telecommunications System (UMTS). 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a part of Evolved UMTS (E-UMTS) using E-UTRA. 3GPP LTE adopts OFDMA in DL and SC-FDMA in UL. LTE-Advanced (LTE-A) is an evolved version of 3GPP LTE.

[0038] For ease of description, the implementation of the present disclosure is mainly described with respect to a 3GPP-based wireless communication system. However, the technical features of the present disclosure are not limited thereto.

[0045] The technical features described separately in one figure in the present disclosure can be implemented separately or simultaneously.

[0046] Although not limited thereto, the various descriptions, functions, processes, suggestions, methods and / or operational flowcharts of the present disclosure disclosed herein may be applied to various fields requiring wireless communication and / or connection between devices (e.g., 5G).

[0047] Hereinafter, the present disclosure will be described in more detail with reference to the accompanying drawings. Unless otherwise specified, the same reference numerals in the following drawings and / or descriptions may refer to the same and / or corresponding hardware blocks, software blocks and / or functional blocks.

[0048] Figure 1 An example of a communication system to which an implementation of the present disclosure is applied is shown.

[0049] exist Figure 1 The 5G usage scenarios shown in the present disclosure are only exemplary, and the technical features of the present disclosure may be applied to Figure 1 Other 5G usage scenarios shown in .

[0050] The three main demand categories for 5G include: (1) enhanced mobile broadband (eMBB) category, (2) massive machine type communication (mMTC) category, and (3) ultra-reliable and low-latency communication (URLLC) category.

[0051] Some use cases may require multiple categories for optimization, and other use cases may focus on only one key performance indicator (KPI). 5G supports such various use cases using a flexible and reliable approach.

[0052] eMBB goes far beyond basic mobile Internet access and covers rich two-way work and media and entertainment applications in the cloud and augmented reality. Data is one of the core driving forces of 5G, and in the 5G era, dedicated voice services may not be provided for the first time. In 5G, it is expected that voice will be simply processed as an application using a data connection provided by the communication system. The main reason for increasing business capacity is due to the increase in content size and the increase in the number of applications requiring high data transfer rates. As more and more devices are connected to the Internet, streaming services (audio and video), conversational video, and mobile Internet access will be more widely used. Many of these applications require a connection that is always on in order to push real-time information and alerts to users. Cloud storage and applications are rapidly increasing in mobile communication platforms and can be applied to both work and entertainment. Cloud storage is a special use case that accelerates the growth of uplink data transfer rates. 5G is also used for remote work in the cloud. When using a tactile interface, 5G requires much lower end-to-end latency to maintain a good user experience. Entertainment, such as cloud gaming and video streaming, is another core element that increases the demand for mobile broadband capabilities. Entertainment is essential for smartphones and tablets anywhere including high mobility environments such as trains, vehicles and airplanes. Other use cases are augmented reality for entertainment and information search. In this case, augmented reality requires very low latency and instantaneous data capacity.

[0053] Additionally, one of the most anticipated 5G use cases involves the ability to smoothly connect embedded sensors in all fields, i.e., mMTC. It is expected that the number of potential Internet of Things (IoT) devices will reach 204 billion by 2020. Industrial IoT is one of the categories that performs a major role in enabling smart cities, asset tracking, smart utilities, agriculture, and security infrastructure through 5G.

[0054] URLLC includes remote control and ultra-reliable / available low-latency links over the main infrastructure that will transform new services in industry (such as autonomous vehicles). The level of reliability and latency is necessary to control smart grids, automate industry, enable robotics, and control and adjust drones.

[0055] 5G is a means of providing streams estimated at hundreds of megabits per second to gigabits per second, and can complement fiber to the home (FTTH) and cable-based broadband (or DOCSIS). Such fast speeds are needed to deliver TV at a resolution of 4K or more (6K, 8K and more), as well as virtual reality and augmented reality. Virtual reality (VR) and augmented reality (AR) applications include almost immersive sports games. Specific applications may require special network configurations. For example, for VR games, game companies need to merge core servers into the network operator's edge network servers to minimize latency.

[0056] It is expected that cars, together with many use cases for mobile communications for vehicles, are new and important motivating forces in 5G. For example, the entertainment of passengers requires high simultaneous capacity and mobile broadband with high mobility. This is because future users continue to expect high-quality connections, regardless of their location and speed. Another use case in the automotive field is the AR dashboard. The AR dashboard enables the driver to identify objects in the dark in addition to the objects seen from the front window, and displays the distance to the object and the movement of the object by overlapping the information told by the driver. In the future, the wireless module realizes the communication between vehicles, the information exchange between the vehicle and the supporting infrastructure, and the information exchange between the vehicle and other connected devices (e.g., devices accompanied by pedestrians). The safety system guides the alternative route of the behavior so that the driver can drive more safely, thereby reducing the risk of accidents. The next stage will be remotely controlled or self-driving vehicles. This requires very high reliability and very fast communication between different self-driving vehicles and between vehicles and infrastructure. In the future, self-driving vehicles will perform all driving activities, and the driver will only focus on abnormal traffic that the vehicle cannot recognize. The technical requirements of self-driving vehicles require ultra-low latency and ultra-high reliability, so that traffic safety is increased to a level that cannot be achieved by humans.

[0057] Smart cities and smart homes / buildings, referred to as smart societies, will be embedded in high-density wireless sensor networks. Distributed networks of smart sensors will identify conditions for cost and energy efficient maintenance of cities or homes. Similar configurations can be performed for corresponding homes. All temperature sensors, window and heating controllers, burglar alarms and home appliances are wirelessly connected. Many of these sensors are typically low in data transfer rate, power and cost. However, certain types of devices may require real-time HD video to perform monitoring.

[0058] The consumption and distribution of energy, including heat or gas, is distributed at a higher level, making it necessary to automatically control the distribution sensor network. Smart grids collect information and use digital information and communication technologies to connect sensors to each other, so as to act according to the collected information. Since this information can include the behavior of supply companies and consumers, smart grids can improve the distribution of fuels such as electricity by methods with efficiency, reliability, economic feasibility, production sustainability and automation. Smart grids can also be considered as another sensor network with low latency.

[0059] Mission-critical applications (e.g., e-health) are one of the 5G use cases. The health segment includes many applications that can enjoy the benefits of mobile communications. Communication systems can support telemedicine that provides clinical treatment in remote locations. Telemedicine can help reduce barriers to distance and improve access to medical services that are not continuously available in remote rural areas. Telemedicine is also used to perform important treatments and save lives in emergency situations. Wireless sensor networks based on mobile communications can provide remote monitoring and sensors for parameters such as heart rate and blood pressure.

[0060] Wireless and mobile communications are becoming increasingly important in the field of industrial applications. Cabling is expensive in terms of installation and maintenance. Therefore, the possibility of replacing cables with reconfigurable radio links is an attractive opportunity in many industrial fields. However, in order to achieve this replacement, wireless connections need to be established with latency, reliability and capacity similar to cables, and the management of wireless connections needs to be simplified. When it comes to connecting to 5G, low latency and very low error probability are new requirements.

[0061] Logistics and freight tracking are important use cases for mobile communications, which allow inventory and packages to be tracked anywhere using location-based information systems. The use cases for logistics and freight tracking typically require low data rates but require location information with wide range and reliability.

[0108] Figure 6 and Figure 7 An example of a protocol stack in a 3GPP-based wireless communication system to which an implementation of the present disclosure is applied is shown.

[0109] Specifically, Figure 6 An example of a radio interface user plane protocol stack between a UE and a BS is illustrated, and Figure 7 An example of a radio interface control plane protocol stack between a UE and a BS is illustrated. The control plane refers to a path through which control messages for managing calls made between a UE and a network are transmitted. The user plane refers to a path through which data generated in an application layer (e.g., voice data or Internet packet data) is transmitted. Figure 6 , the user plane protocol stack can be divided into layer 1 (ie, PHY layer) and layer 2. Figure 7 , the control plane protocol stack can be divided into layer 1 (ie, PHY layer), layer 2, layer 3 (eg, RRC layer), and non-access stratum (NAS) layer. Layer 1, layer 2, and layer 3 are called access stratum (AS).

[0110] In the 3GPP LTE system, Layer 2 is separated into the following sublayers: MAC, RLC, and PDCP. In the 3GPP NR system, Layer 2 is separated into the following sublayers: MAC, RLC, PDCP, and SDAP. The PHY layer provides transport channels to the MAC sublayer, the MAC sublayer provides logical channels to the RLC sublayer, the RLC sublayer provides RLC channels to the PDCP sublayer, and the PDCP sublayer provides radio bearers to the SDAP sublayer. The SDAP sublayer provides Quality of Service (QoS) flows to the 5G core network.

[0111] In the 3GPP NR system, the main services and functions of the MAC sublayer include: mapping between logical channels and transport channels; multiplexing / demultiplexing MAC SDUs belonging to one or different logical channels to / from transport blocks (TBs) on transport channels for delivery to / from the physical layer; scheduling information reporting; error correction through hybrid automatic repeat request (HARQ) (one HARQ entity per cell in the case of carrier aggregation (CA); priority handling between UEs through dynamic scheduling; priority handling between logical channels of one UE through logical channel prioritization; padding. A single MAC entity can support multiple parameter sets, transmission timings, and cells. The mapping restrictions in the logical channel prioritization control which parameter set(s), cell, and transmission timing can be used by the logical channel.

[0112] MAC provides different kinds of data transmission services. In order to accommodate different kinds of data transmission services, multiple types of logical channels are defined, that is, each logical channel supports the transmission of a specific type of information. Each logical channel type is defined by what type of information is transmitted. Logical channels are divided into two groups: control channels and traffic channels. Control channels are used only for the transmission of control plane information, and traffic channels are used only for the transmission of user plane information. The broadcast control channel (BCCH) is a downlink logical channel for broadcasting system control information, the paging control channel (PCCH) is a downlink logical channel for transmitting paging information, system information change notifications, and indications of ongoing public warning services (PWS) broadcasts, the common control channel (CCCH) is a logical channel used to send control information between the UE and the network and is used by UEs that do not have an RRC connection with the network, and the dedicated control channel (DCCH) is a point-to-point bidirectional logical channel used by UEs with RRC connections to send dedicated control information between the UE and the network. The dedicated traffic channel (DTCH) is a point-to-point logical channel dedicated to one UE for transmitting user information. DTCH can exist in both the uplink and downlink. In the downlink, there are the following connections between logical channels and transport channels: BCCH can be mapped to the broadcast channel (BCH); BCCH can be mapped to the downlink shared channel (DL-SCH); PCCH can be mapped to the paging channel (PCH); CCCH can be mapped to DL-SCH; DCCH can be mapped to DL-SCH; and DTCH can be mapped to DL-SCH. In the uplink, there are the following connections between logical channels and transport channels: CCCH can be mapped to the uplink shared channel (UL-SCH); DCCH can be mapped to UL-SCH; and DTCH can be mapped to UL-SCH.

[0113] The RLC sublayer supports three transmission modes: transparent mode (TM), unacknowledged mode (UM) and acknowledged mode (AM). The RLC configuration is per logical channel without dependency on parameter sets and / or transmission duration. In 3GPP NR systems, the main services and functions of the RLC sublayer depend on the transmission mode and include: delivery of upper layer PDUs; sequence numbering independent of sequence numbering in PDCP (UM and AM); error correction through ARQ (AM only); segmentation (AM and UM) and re-segmentation (AM only) of RLC SDUs; reassembly of SDUs (AM and UM); duplicate detection (AM only); RLC SDU discard (AM and UM); RLC re-establishment; protocol error detection (AM).

[0114] In the 3GPP NR system, the main services and functions of the PDCP sublayer for the user plane include: sequence numbering; header compression and decompression using robust header compression (RoHC); transmission of user data; reordering and duplicate detection; in-sequence delivery; PDCP PDU routing (in the case of split bearers); retransmission of PDCP SDU; ciphering, deciphering and integrity protection; PDCP SDU discard; PDCP re-establishment and data recovery for RLC AM; PDCP status reporting for RLC AM; PDCP PDU duplication and duplicate discard indication to lower layers. The main services and functions of the PDCP sublayer for the control plane include: sequence numbering; ciphering, deciphering and integrity protection; transmission of control plane data; reordering and duplicate detection; in-sequence delivery; PDCP PDU duplication and duplicate discard indication to lower layers.

[0115] In 3GPP NR system, the main services and functions of SDAP include: mapping between QoS flows and data radio bearers; marking QoS flow ID (QFI) in both DL and UL packets. A single protocol entity of SDAP is configured for each individual PDU session.

[0116] In the 3GPP NR system, the main services and functions of the RRC sublayer include: broadcast of system information related to AS and NAS; paging initiated by 5GC or NG-RAN; establishment, maintenance and release of RRC connection between UE and NG-RAN; security functions including key management; establishment, configuration, maintenance and release of signaling radio bearers (SRBs) and data radio bearers (DRBs); mobility functions (including: handover and context transfer, UE cell selection and reselection and control of cell selection and reselection, inter-RAT mobility); QoS management functions; UE measurement reporting and control of reporting; detection and recovery of radio link failures; NAS message transmission from UE to NAS / from NAS to UE.

[0117] Figure 8 The frame structure in a 3GPP-based wireless communication system to which the implementation of the present disclosure is applied is shown.

[0118] Figure 8The frame structure shown in is merely exemplary, and the number of subframes, the number of time slots, and / or the number of symbols in a frame may vary. In a 3GPP-based wireless communication system, OFDM parameter sets (e.g., subcarrier spacing (SCS), transmission time interval (TTI) duration) may be configured differently between multiple cells aggregated for one UE. For example, if the UE is configured with different SCSs for cells aggregated for the cell, the (absolute time) duration of time resources (e.g., subframes, time slots, or TTIs) including the same number of symbols may be different among the aggregated cells. In this article, the symbol may include an OFDM symbol (or CP-OFDM symbol), an SC-FDMA symbol (or a discrete Fourier transform-spread-OFDM (DFT-s-OFDM) symbol).

[0119] Reference Figure 8 , downlink and uplink transmissions are organized into frames. Each frame has T f = 10ms duration. Each frame is divided into two half-frames, where each half-frame has a duration of 5ms. Each half-frame includes 5 sub-frames, where the duration of each sub-frame is T sf is 1ms. Each subframe is divided into time slots, and the number of time slots in a subframe depends on the subcarrier spacing. Each time slot includes 14 or 12 OFDM symbols based on the cyclic prefix (CP). In a normal CP, each time slot includes 14 OFDM symbols, and in an extended CP, each time slot includes 12 OFDM symbols. The parameter set is based on an exponentially scalable subcarrier spacing Δf=2u*15kHz.

[0120] Table 1 shows the subcarrier spacing according to Δf=2 u *N is the number of OFDM symbols per time slot of 15kHz slot symb , the number of time slots per frame N frame，u slot , and the number of time slots N per subframe for normal CP subframe，u slot .

[0121] [Table 1]

[0123] Table 2 shows the subcarrier spacing according to Δf=2 u *N is the number of OFDM symbols per time slot of 15kHz slot symb , the number of time slots per frame N frame，u slot , and the number of time slots N per subframe for the extended CP subframe，uslot .

[0125] u <![CDATA[N slot symb ]]> <![CDATA[N frame，u slot ]]> <![CDATA[N subframe，u slot ]]> 2 12 40 4

[0126] A slot includes a plurality of symbols (e.g., 14 or 12 symbols) in the time domain. For each parameter set (e.g., subcarrier spacing) and carrier, a common resource block (CRB) N indicated by higher layer signaling (e.g., RRC signaling) is allocated. start，u grid To begin, we define N size，u grid，x *N RB sc subcarriers and N subframe，u symb OFDM symbol resource grid, where N size，u grid，x is the number of resource blocks (RBs) in the resource grid, and the subscript x is DL for the downlink and UL for the uplink. N RB sc is the number of subcarriers per RB. In 3GPP-based wireless communication systems, N RB sc Typically 12. For a given antenna port p, subcarrier spacing configuration u, and transmission direction (DL or UL), there is one resource grid. The carrier bandwidth N for subcarrier spacing configuration u size，u grid Given by high-level parameters (e.g., RRC parameters). Each element in the resource grid for antenna port p and subcarrier spacing configuration u is called a resource element (RE), and one complex symbol can be mapped to each RE. Each RE in the resource grid is uniquely identified by an index k in the frequency domain and an index 1 representing the symbol position relative to a reference point in the time domain.

[0127] In 3GPP-based wireless communication systems, an RB is defined by 12 consecutive subcarriers in the frequency domain. In 3GPP NR systems, RBs are classified into CRBs and physical resource blocks (PRBs). CRBs are numbered upwards from 0 in the frequency domain for subcarrier spacing configuration u. The center of subcarrier 0 of CRB 0 for subcarrier spacing configuration u coincides with "point A" used as a common reference point for the resource block grid. In 3GPP NR systems, PRBs are defined within bandwidth parts (BWPs) and are numbered from 0 to N. size BWP，i -1 numbering, where i is the number of the bandwidth part. Physical resource block n in bandwidth part i PRB With common resource block n CRB The relationship between is as follows: PRB =nCRB +N size BWP,i , where N size BWP,i It is a common resource block where the bandwidth part starts relative to CRB 0. A BWP includes multiple consecutive RBs. A carrier can include up to N (e.g., 5) BWPs. A UE can be configured with one or more BWPs on a given component carrier. Only one BWP can be activated at a time among the BWPs configured for a UE. The active BWP defines the operating bandwidth of the UE within the operating bandwidth of the cell.

[0128] The NR frequency band may be defined as two types of frequency ranges, namely, FR1 and FR2. The numerical values ​​of the frequency ranges may vary. For example, the two types of frequency ranges (FR1 and FR2) may be as shown in Table 3 below. For ease of explanation, in the frequency range used in the NR system, FR1 may mean "sub-6 GHz range", FR2 may mean "above 6 GHz range" and may be referred to as millimeter wave (mmW).

[0131] As described above, the numerical value of the frequency range of the NR system can be changed. For example, FR1 may include a frequency band of 410 MHz to 7125 MHz, as shown in Table 4 below. That is, FR1 may include a frequency band of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or more. For example, a frequency band of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or more included in FR1 may include an unlicensed frequency band. The unlicensed frequency band may be used for various purposes, such as for communication of vehicles (e.g., autonomous driving).

[0134] In the present disclosure, the term "cell" may refer to a geographical area where one or more nodes provide a communication system or to a radio resource. "Cell" as a geographical area can be understood as a coverage range in which a node can provide services using a carrier, and "cell" as a radio resource (e.g., time-frequency resource) is associated with a bandwidth, which is a frequency range configured by a carrier. A "cell" associated with a radio resource is defined by a combination of downlink resources and uplink resources (e.g., a combination of DL component carriers (CCs) and UL CCs). A cell may be configured only by downlink resources, or may be configured by downlink resources and uplink resources. Since the DL coverage (which is the range in which a node can send a valid signal) and the UL coverage (which is the range in which a node can receive a valid signal from a UE) depend on the carrier that carries the signal, the coverage of a node may be associated with the coverage of a "cell" of a radio resource used by the node. Therefore, the term "cell" may be used to sometimes represent the service coverage of a node, to represent a radio resource at other times, or to represent the range in which a signal using a radio resource can reach with effective strength at other times.

[0135] In CA, two or more CCs are aggregated. The UE can receive or transmit on one or more CCs simultaneously according to its capabilities. CA is supported for both continuous CCs and non-contiguous CCs. When CA is configured, the UE has only one RRC connection with the network. When the RRC connection is established / reestablished / switched, one serving cell provides NAS mobility information, and when the RRC connection is reestablished / switched, one serving cell provides security input. This cell is called the primary cell (PCell). PCell is a cell operating on the primary frequency, where the UE performs an initial connection establishment process or initiates a connection reestablishment process. Depending on the UE capabilities, the secondary cell (SCell) can be configured to form a set of serving cells together with the PCell. SCell is a cell that provides additional radio resources on top of a special cell (PCell). Therefore, the set of configured serving cells for the UE always consists of one PCell and one or more SCells. For dual connection (DC) operation, the term "PCell" refers to the PCell of the primary cell group (MCG) or the primary SCell (PSCell) of the secondary cell group (SCG). SpCell supports PUCCH transmission and contention-based random access and is always activated. MCG is a set of serving cells associated with the master node, which includes SpCell (PCell) and optionally one or more SCells. For UEs configured with DC, SCG is a subset of serving cells associated with the secondary node, which includes PSCell and zero or more SCells. For UEs in RRC_CONNECTED that are not configured with CA / DC, there is only one serving cell consisting of PCell. For UEs in RRC_CONNECTED that are configured with CA / DC, the term "serving cell" is used to refer to the set of cells consisting of SpCell and all SCells. In DC, two MAC entities are configured in the UE: one for MCG and one for SCG.

[0136] Fig. 9 An example of data flow in a 3GPP NR system to which an implementation of the present disclosure is applied is shown.

[0137] Reference Fig. 9 , "RB" means radio bearer, and "H" means header. Radio bearers are classified into two groups: DRB for user plane data and SRB for control plane data. MAC PDU is transmitted / received to / from an external device through the PHY layer using radio resources. MAC PDU arrives at the PHY layer in the form of a transport block.

[0138] In the PHY layer, uplink transport channels UL-SCH and RACH are mapped to their physical channels PUSCH and PRACH, respectively, and downlink transport channels DL-SCH, BCH and PCH are mapped to PDSCH, PBCH and PDSCH, respectively. In the PHY layer, uplink control information (UCI) is mapped to physical PUCCH, and downlink control information (DCI) is mapped to PDCCH. MAC PDU related to UL-SCH is sent by UE via PUSCH based on UL grant, and MAC PDU related to DL-SCH is sent by BS via PDSCH based on DL assignment.

[0283] Describes operations related to UE information.

[0284] Fig.11 An example of a UE information procedure is shown.

[0285] E-UTRAN uses the UE Information procedure to request the UE to report information.

[0286] The E-UTRAN initiates this procedure by sending a UEInformationRequest message. The E-UTRAN shall initiate this procedure only after successful security activation.

[0287] Upon receipt of the UEInformationRequest message, the UE shall, only after successful security activation:

[0288] If the flightPathInfoReq field is present and the UE has flight path information available, then:

[0289] 2> Include flightPathInfoReport and set it to include a list of waypoints along the flight path;

[0290] 2>If includeTimeStamp is set to true:

[0291] 3> If this information is available at the UE, the field timeStamp is set to the time the UE aims to arrive at each waypoint;

[0292] For example, the UEInformationRequest message may include flightPathInfoReq-r15 and nonCriticalExtension. FlightPathInfoReq-r15 may include FlightPathInfoReportConfig-r15.

[0293] For example, the UEInformationResponse message may include (i) measResultListIdle-r15 (MeasResultListIdle-r15), (ii) flightPathInfoReport-r15 (FlightPathInfoReport-r15), and (iii) nonCriticalExtension (UEInformationResponse-v1610-IE).

[0294] For example, configure FlightPathInfoReport-r15 as follows:

[0295]

[0296] Table 5 shows an example of the LocationInfo information element.

[0297] The IE LocationInfo is used to convey detailed location information available at the UE to correlate measurements with the UE location information.

[0298] [Table 5]

[0299]

[0300]

[0301] In the following, technical features related to supporting over-the-air UE communications are described. Reference may be made to a portion of Section 23.17 of 3GPP TS 36.300 v16.5.0. The E-UTRAN-based mechanism for providing LTE connectivity to UEs capable of over-the-air communications is supported via the following functions:

[0302] -Subscription based over-the-air UE identification and authentication.

[0303] - Altitude reporting based on the event that the UE's altitude has crossed a network configured reference altitude threshold.

[0304] - Interference detection based on measurement reports, which are triggered when the number of configured cells (ie, greater than 1) simultaneously meets the triggering criteria.

[0305] -Signaling of flight path information from UE to E-UTRAN.

[0306] - Position information report, including horizontal and vertical speed of the UE.

[0307] <Subscription-based identification of over-the-air UE capabilities>

[0308] The support of over-the-air UE functionality is stored in the user's subscription information in the HSS. The HSS transmits this information to the MME during the attach, service request and tracking area update procedures.

[0309] The subscription information may be provided from the MME to the eNB via the S1 AP Initial Context Setup Request during the Attach, Tracking Area Update and Service Request procedures. Additionally, for X2-based handovers, the source eNodeB may include the subscription information in the X2-AP Handover Request message to the target eNodeB.

[0310] For intra-MME and inter-MME S1 based handover, the MME provides subscription information to the target eNB after the handover procedure.

[0311] <Altitude-based reporting for airborne UE communications>

[0312] An aerial UE can be configured with event-based altitude reporting. When the altitude of an aerial UE is above or below a configured threshold, the UE sends an altitude report. If configured, the report contains both altitude and position.

[0313] <Interference Detection and Mitigation for Over-the-Air UE Communications>

[0314] For interference detection, the airborne UE can be configured with RRM event A3, RRM event A4 or RRM event A5. When the single (per cell) RSRP value of the configured number of cells meets the configured event, RRM event A3, RRM event A4 or RRM event A5 triggers a measurement report. If configured, the report contains the RRM results and location.

[0315] For interference mitigation, over-the-air UEs may be configured with a dedicated UE-specific α parameter for PUSCH power control.

[0316] <Flight Path Information Report>

[0317] The E-UTRAN may request the UE to report flight path information consisting of multiple waypoints defined as 3D positions. If the flight path information is available at the UE, the UE reports up to the configured number of waypoints. The report may also include a timestamp for each waypoint if configured in the request and if available at the UE.

[0318] <Position Reporting for Over-the-Air UE Communications>

[0319] If configured, the location information for airborne UE communications may include horizontal and vertical speeds. The location information may be included in RRM reports and altitude reports.

[0320] In the following, technical features related to measurement report triggering are described. Reference may be made to a part of section 5.5.4 of 3GPP TS 38.331 v17.0.0.

[0485] In the following, technical features related to UE assistance information are described. Reference may be made to a part of section 5.7.4 of 3GPP TS 36.300 v16.5.0.

[0486] Fig.12 An example of UE assistance information is shown.

[0487] The purpose of this procedure is to inform the network that:

[0488] - its delay budget report carrying the expected increment / decrement of the connected mode DRX cycle length, or;

[0489] - its overheating assistance information, or;

[0490] - its IDC auxiliary information, or;

[0491] - its preference for DRX parameters to save power, or;

[0492] - its preference for maximum aggregate bandwidth to save power, or;

[0493] - its preference for the maximum number of secondary component carriers to save power, or;

[0494] - its preference for the maximum number of MIMO layers to save power, or;

[0495] - its preference for minimum scheduling offset across time slots to save power, or;

[0496] - its preference for RRC state, or;

[0497] - configuration grant assistance information for NR sidelink communications, or;

[0498] - their preference to be provided with reference time information, or;

[0499] - its preference for FR2 UL clearance, or

[0500] - its preference to transition from the RRC_CONNECTED state for MUSIM operation, or;

[0501] - their preference for MUSIM gaps, or;

[0502] - its relaxed state for RLM measurement, or;

[0503] - its relaxed state with respect to BFD measurement, or;

[0504] - the availability of data mapped to a radio bearer not configured for SDT; or;

[0505] - their preferences for the SCGs to be deactivated, or;

[0506] - indicates that the UE has uplink data to send for a DRB for which no MCG RLC bearer exists when the SCG is deactivated, or;

[0507] -Change the satisfaction status of the relaxation criteria for RRM measurements.

[0508] Additionally, for airborne UEs, it indicates the availability of the flight path during handover or RRC connection related operations. The network can request flight path information and the UE can respond with relevant details. In other words, flight path information is shared with the network only when requested. The network uses this information to derive the appropriate configuration (including mobility, beam-related settings, and access control). The flight path plays a crucial role in enabling the network to determine the optimized UE configuration (e.g., through AI / ML algorithms).

[0509] Currently, the UE only informs the network of the availability of flight path information during a cell change or handover. Therefore, any updates to the flight path due to air traffic or weather conditions cannot be immediately reported to the network. This problem is particularly important in cells with wide coverage such as NTN, where high-speed UEs can significantly change their location within the same cell without triggering a handover or reporting updated flight path information.

[0510] Therefore, it is crucial to enable the UE to report updated flight path information to the network within the same cell. One approach is to enable the UE to report the flight path information each time the flight path information is updated. However, according to the traditional process, notifying the flight path information requires three steps: i) notifying the updated flight path from the UE; ii) requesting the flight path information from the network; iii) sending the flight path information from the UE. Unconditionally reporting this information will introduce downlink / uplink interference in the LOS environment and increase the signaling overhead. Even if the UE notifies all flight path information without a network command in step i), steps ii) and iii) may not be necessary from the network's perspective. However, in certain locations, this information may be absolutely necessary.

[0511] Therefore, there is a need to study flight path reporting in wireless communication systems.

[0512] Hereinafter, a method for flight path reporting in a wireless communication system according to some embodiments of the present disclosure will be described with reference to the following drawings.

[0513] The following figures are created to explain specific embodiments of the present disclosure. The specific device names or specific signal / message / field names shown in the figures are provided as examples, so the technical features of the present disclosure are not limited to the specific names used in the following figures. In this article, a wireless device may be referred to as a user equipment (UE).

[0514] Fig.13 An example of a method for flight path reporting in a wireless communication system according to some embodiments of the present disclosure is shown.

[0515] Specifically, Fig.13 An example of a method performed by a wireless device in a wireless communication system is shown.

[0516] In step S1301 , the wireless device may receive a configuration for flight path information including conditions related to a specific location from a network.

[0517] For example, the condition associated with the specific location may be satisfied based on the following situations: (i) the wireless device enters the specific location from outside the specific location, or (ii) the wireless device leaves the specific location from outside the specific location. That is, when (i) the wireless device enters the specific location from outside the specific location, or (ii) the wireless device leaves the specific location from outside the specific location, it can be determined that the condition associated with the specific location is satisfied.

[0518] For example, the wireless device may send a radio resource control (RRC) reconfiguration complete message including the flight path available indication to the network. That is, the wireless device may send the RRC reconfiguration complete message including the flight path available indication before sending the first message in step S1302.

[0519] In step S1302, the wireless device may send a first message including information about a first flight path to a network.

[0520] For example, the wireless device may receive a UE information request message for flight path information from the network. The wireless device may send a first message including information about the first flight path to the network in response to the UE information request message. That is, the first message including information about the first flight path may be a UE information response message that responds to the UE information request message.

[0521] For example, the wireless device may receive an RRC reconfiguration including a configuration for the flight path information from the network.For example, the wireless device may receive an RRC reconfiguration including a configuration for the flight path information after sending the first message.

[0522] In step S1303 , the wireless device may determine whether the flight path of the wireless device is updated from the first flight path to the second flight path.

[0523] In step S1304, based on (i) the current location of the wireless device satisfies the condition related to the specific location, and (ii) the flight path is updated, the wireless device may send a second message including information about the second flight path to the network.

[0524] For example, the information about the second flight path may include all waypoints of the second flight path.

[0525] For example, the information about the second flight path may include one or more waypoints of the second flight path that are different from the first flight path.

[0526] For example, the second message may include UE Assistance Information (UAI). The UAI may include information of the second flight path.

[0527] According to some embodiments of the present disclosure, the information of the second flight path may include an indication notifying the wireless device that the flight path is updated. That is, based on (i) the current location of the wireless device satisfies a condition related to a specific location, and (ii) the flight path is updated, the wireless device may send a second message including information that the flight path of the wireless device has been updated to the second flight path to the network. In this case, the wireless device may send a third message including one or more path points of the second flight path to the network.

[0528] According to some embodiments of the present disclosure, a wireless device may send a measurement report including an indication that a flight path of the wireless device is updated to a network. The wireless device may receive a UE information request message for flight path information from the network. Then, the wireless device may send a UE information response message as a second message to the network. That is, the second message may be a UE information response message that responds to the UE information request message.

[0529] According to some embodiments of the present disclosure, a wireless device may communicate with at least one of a user device other than itself, a network, or an autonomous driving vehicle.

[0530] Fig.14 An example of a method for flight path reporting in a wireless communication system according to some embodiments of the present disclosure is shown.

[0531] Specifically, Fig.14 An example of a method performed by a wireless device in a wireless communication system is shown.

[0532] exist Fig.14 In this method, the location where the latest flight path of the UE is required is introduced. In terms of cell planning of the network, the network can request the latest flight path information from a specific location for mobility management, beam management and access control. Within a cell, the flight path information is only required when the flight path information has been updated.

[0533] For example, the network configures a specific location. While moving through the flight path, the UE derives its own location and whether the flight path has been updated. If the UE enters the specific location and if the flight path has been updated, the UE notifies the network of the updated flight path information.

[0534] In step S1401, the UE receives a configuration including information about a specific location for flight path update from a network.

[0535] That is, the network may configure specific location information for the UE for flight path updating.
