Description

Technical Field

[0001] The present disclosure relates to a wireless communication system, and more particularly, to a method and apparatus for processing a wireless transmission profile used when an unmanned aerial vehicle terminal sends and receives service messages based on U2X communication via a PC5 interface in the wireless communication system. Background Art

[0002] Fifth-generation (5G) mobile communication technology defines wide frequency bands to enable high transmission rates and new services. 5G mobile communication technology can be implemented not only in "sub-6 GHz" frequency bands such as 3.5 GHz, but also in ultra-high frequency ("above 6 GHz") bands known as mmWave, such as 28 GHz and 39 GHz. Furthermore, to achieve transmission rates fifty times faster than 5G mobile communication technology and ultra-low latency one-tenth that of 5G mobile communication technology, 6G mobile communication technology (referred to as a "beyond 5G system") is being considered in the terahertz frequency band (e.g., the 95 GHz to 3 THz band).

[0003] In the early stages of 5G mobile communication technology, in order to support services associated with enhanced Mobile Broadband (eMBB), Ultra Reliable & Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC) and meet the performance requirements associated therewith, standardization is underway on the following items: beamforming and massive MIMO for mitigating radio wave path loss and increasing radio wave transmission range in millimeter waves, parameter sets (numerology, for example, operating multiple subcarrier spacings) for efficient utilization of millimeter wave resources and dynamic operation of time slot formats, initial access technology supporting multi-beam transmission and broadband, definition and operation of BWP (bandwidth part), new channel coding methods such as LDPC (low-density parity check) codes for large-capacity data transmission and polar codes for highly reliable transmission of control information, L2 preprocessing, and network slicing for providing dedicated networks tailored to specific services.

[0004] Currently, in view of the services to be supported by 5G mobile communication technology, discussions are underway on improvements and performance enhancements of initial 5G mobile communication technology, and there is already physical layer standardization on technologies such as: Vehicle-to-everything (V2X) for assisting driving determination of autonomous vehicles based on information about the location and status of vehicles sent by the vehicles and for enhancing user convenience, New Radio Unlicensed (NR-U) for system operation in unlicensed frequency bands that complies with various regulatory requirements, NR UE energy saving, Non-Terrestrial Network (NTN) as UE-satellite direct communication for ensuring coverage in areas where communication with terrestrial networks is unavailable, and positioning.

[0005] Furthermore, in the area of ​​radio interface architecture / protocols, standardization is underway on technologies such as the Industrial Internet of Things (IIoT), which supports new services through interworking and integration with other industries; Integrated Access and Backhaul (IAB), which provides nodes for expanding network service areas by integrating wireless backhaul and access links; mobility enhancements including conditional handover and Dual Active Protocol Stack (DAPS) handover; and two-step random access (NR two-step RACH) for simplifying the random access procedure. In the area of ​​system architecture / services, standardization is also underway on a 5G baseline architecture (e.g., a service-based architecture or service-based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies; and Mobile Edge Computing (MEC), which allows for receiving services based on the location of the UE.

[0006] If such a 5G mobile communication system is commercialized, the already exponentially growing number of connected devices will be connected to the communication network, and it is therefore expected that enhanced functionality and performance of the 5G mobile communication system and the integrated operation of connected devices will be necessary. To this end, new research is being planned related to: xtended reality (XR) for efficient support of augmented reality (AR), virtual reality (VR), mixed reality (MR), etc.; 5G performance improvement and complexity reduction through the use of artificial intelligence (AI) and machine learning (ML); support for AI services; support for metaverse services; and drone communications.

[0007] Furthermore, such advancements in 5G mobile communication systems will serve not only as a foundation for the development of new waveforms, Full Dimensional MIMO (FD-MIMO), multi-antenna transmission technologies (such as array antennas and massive antennas) for ensuring coverage in the terahertz band for 6G mobile communication technology, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional spatial multiplexing technologies using orbital angular momentum (OAM), and reconfigurable intelligent surfaces (RIS), but will also serve as a foundation for the development of full-duplex technologies for improving the frequency efficiency and system networks of 6G mobile communication technology, AI-based communication technologies for achieving system optimization by leveraging satellites and AI (artificial intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technologies for implementing services with a complexity level that exceeds the operational capabilities of UEs by utilizing ultra-high-performance communication and computing resources.

[0023] UE-to-UE direct communication (sidelink communication) using the 5G communication system is being studied, and it is expected to be applied to, for example, vehicle-to-everything (V2X) networks, public safety networks, and drone communications, and thus UE-to-UE direct communication can provide various services to users.

[0024] Embodiments of the present disclosure provide a method and apparatus for processing a TX profile, ie, a wireless transmission profile, for sending and receiving service messages of an unmanned aerial vehicle in a wireless communication system supporting unmanned aerial vehicles.

[0025] The technical subject matter involved in the present disclosure may not be limited to the above-mentioned technical subject matter, and those skilled in the art to which the present disclosure belongs may clearly understand other technical subject matter not mentioned herein from the following description.

[0026] The embodiments of the present disclosure can provide secure drone communication or urban air mobility communication in a wireless communication system.

[0027] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that in the accompanying drawings, identical or similar elements are referred to by identical or similar reference numerals as much as possible. In addition, detailed descriptions of known functions or configurations that may make the subject matter of the present disclosure unnecessarily unclear will be omitted.

[0028] When describing the embodiments of this specification, descriptions related to technical contents well-known in the relevant field and not directly related to the present disclosure will be omitted. Such unnecessary descriptions are omitted in order to prevent the main idea of ​​the present disclosure from being obscured and to convey the main idea more clearly.

[0029] For the same reason, in the accompanying drawings, some elements may be exaggerated, omitted or schematically shown. In addition, the size of each element does not fully reflect the actual size. In the various drawings, the same or corresponding elements are assigned the same reference numerals.

[0030] The advantages and features of the present disclosure and the manner in which they are achieved will become apparent by reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present disclosure is not limited to the embodiments set forth below, but may be implemented in various forms. The following embodiments are provided only to fully disclose the present disclosure and to inform those skilled in the art of the scope of the present disclosure, and the present disclosure is limited only by the scope of the appended claims. Throughout the specification, the same or similar reference numerals indicate the same or similar elements.

[0031] Here, it will be understood that each box of the flowchart diagram and the combination of boxes in the flowchart diagram can be implemented by computer program instructions. These computer program instructions can be provided to the processor of a general-purpose computer, a special-purpose computer or other programmable data processing device to produce a machine so that the instructions run by the processor of the computer or other programmable data processing device create a component for implementing the function specified in one or more flowchart boxes. These computer program instructions can also be stored in a computer-usable or computer-readable memory, which can guide the computer or other programmable device to operate in a particular manner so that the instructions stored in the computer-usable or computer-readable memory produce an article of manufacture including an instruction component that implements the function specified in one or more flowchart boxes. The computer program instructions can also be loaded onto a computer or other programmable data processing device so that a series of operating steps are executed on the computer or other programmable device to produce a computer-implemented process so that the instructions running on the computer or other programmable device provide steps for implementing the function specified in one or more flowchart boxes.

[0032] In addition, each block in the flowchart diagram may represent a module, code segment, or code portion that includes one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions mentioned in the blocks may not appear in order. For example, two blocks shown in succession may actually run substantially simultaneously, or the blocks may sometimes run in reverse order, depending on the functions involved.

[0033] As used in the embodiments of the present disclosure, the term "unit" refers to a software element or a hardware element, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC), and a "unit" can perform certain functions. However, a "unit" does not always have a meaning limited to software or hardware. A "unit" can be configured to be stored in an addressable storage medium or to run one or more processors. Therefore, a "unit" includes, for example, a software element, an object-oriented software element, a class element or a task element, a process, a function, a property, a procedure, a subroutine, a program code segment, a driver, firmware, microcode, a circuit, data, a database, a data structure, a table, an array, and a parameter. The elements and functions provided by a "unit" can be combined into a smaller number of elements or "units", or divided into a larger number of elements or "units". In addition, elements and "units" can be implemented as replicating one or more CPUs within an equipment or a secure multimedia card.

[0034] The following detailed description of the embodiments of the present disclosure is mainly directed to the New Radio Access Network (New RAN, NR) as the radio access network and the packet core (5G system or 5G core network or next generation core (NG Core)) as the core network in the 5G mobile communication standard specified by the 3rd Generation Partnership Project (3GPP) as a mobile communication standardization group, but based on the determination of those skilled in the art, the main ideas of the present disclosure can be applied to other communication systems with similar backgrounds through some modifications without significantly departing from the scope of the present disclosure.

[0035] In the 5G system, a network data collection and analysis function (NWDAF) can be defined as a network function for analyzing and providing data collected in the 5G network to support network automation. The NWDAF can collect / store / analyze information from the 5G network and provide the results to unspecified network functions (NFs), and the analysis results can be used independently in each NF.

[0036] In the following description, for convenience, some terms and names defined in the 3rd Generation Partnership Project (3GPP) standards (standards for 5G, NR, LTE, or similar systems) may be used. However, the present disclosure is not limited to these terms and names and can be applied in the same manner to systems conforming to other standards.

[0037] In the following description, for the convenience of description, terms referring to signals, terms referring to channels, terms referring to control information, terms referring to network entities, terms referring to equipment elements, etc. are illustratively used. Therefore, the present disclosure is not limited to the terms used herein, and other terms referring to subjects with equivalent technical meanings may be used.

[0038] In the following description, a base station is an entity that allocates resources to terminals and can be at least one of a gNode B, eNode B, Node B, base station (BS), radio access unit, base station controller, and node on a network. Terminals can include user equipment (UE), mobile stations (MS), cellular phones, smartphones, computers, or multimedia systems capable of performing communication functions. However, these are merely examples, and base stations and terminals are not limited to these examples. In this disclosure, for convenience, the term "eNB" may be used interchangeably with the term "gNB." That is, a base station described as an "eNB" may also be referred to as a "gNB." In this disclosure, the term "terminal" can refer not only to mobile phones, NB-IoT equipment, and sensors, but also to various wireless communication equipment.

[0039] In the following description, the terms "physical channel" and "signal" may be used interchangeably with the terms "data" or "control signal." For example, the term "physical downlink shared channel (PDSCH)" refers to a physical channel on which data is transmitted, but PDSCH may also be used to refer to "data." That is, in this disclosure, the expression "transmitting a physical channel" may be interpreted as having the same meaning as the expression "transmitting data or a signal via a physical channel."

[0040] In the following description of this disclosure, higher signaling refers to a signal transmission scheme from a base station to a terminal via a downlink data channel of the physical layer, or from a terminal to a base station via an uplink data channel of the physical layer. Higher signaling can also be understood as radio resource control (RRC) signaling or a media access control (MAC) control element (CE).

[0041] In addition, as used in the present disclosure, the expression "greater than" or "less than" is used to determine whether a specific condition is satisfied or achieved, but this is intended to illustrate examples only and does not exclude "greater than or equal to" or "equal to or less than." A condition indicated by the expression "greater than or equal to" may be replaced by a condition indicated by "greater than," a condition indicated by the expression "equal to or less than" may be replaced by a condition indicated by "less than," and a condition indicated by "greater than and equal to or less than" may be replaced by a condition indicated by "greater than and less than."

[0042] In addition, the present disclosure will be described using terms adopted in some communication standards (eg, the 3rd Generation Partnership Project (3GPP)), but they are for illustrative purposes only. The present disclosure can also be easily applied to other communication systems through modification.

[0043] UE-to-UE direct communication (sidelink communication) using the 5G communication system is being studied, and it is expected that UE-to-UE direct communication will be applied to, for example, vehicle-to-everything (V2X), public safety networks, and drone communications, and thus various services can be provided to users.

[0044] The present disclosure provides a method and apparatus for processing a U2X communication TX profile, which is a wireless transmission profile used to transmit and receive service messages for unmanned aerial vehicles (UAVs) using a PC5 interface in a wireless communication system supporting UAVs. The UAV service messages may include, for example, at least one of information capable of identifying the UAV and control information for controlling the UAV, or a combination thereof.

[0045] According to an embodiment of the present disclosure, by synchronizing wireless transmission profiles between UEs that exchange service messages of unmanned aerial vehicles in a wireless communication system, secure drone communications and urban air mobility communications can be provided.

[0046] The present disclosure may provide a method and apparatus for using a direct communication interface (e.g., PC5 or sidelink) between UEs in a wireless communication system to control an unmanned aerial vehicle (e.g., a drone or unmanned aerial vehicle (UAV)) or control air mobility (e.g., urban air mobility (UAM)) without the need for a pilot or with only limited pilot participation. In the present disclosure, scenarios using a direct communication interface between UEs may include a process for obtaining UAV identification information or UAM identification information of an unmanned aerial vehicle or urban air mobility from an agency that controls the unmanned aerial vehicle or urban air mobility (e.g., an agency responsible for law enforcement such as the Federal Aviation Administration of the United States). Based on a control policy, a UE installed on an unmanned aerial vehicle may send the UAV identification information to a UE managed by the control agency.

[0047] According to an embodiment, a UE may transmit UAV identification information or UAM identification information via a direct communication interface between UEs. In the present disclosure, in addition to messages including UAV identification information or UAM identification information, messages including information required for controlling an unmanned aerial vehicle or urban air mobility may be defined as UAV control messages. Of course, the present disclosure is not limited to this example, and UAV control messages may also include various messages.

[0048] UEs installed on unmanned aerial vehicles, UEs installed on urban air mobility systems, or UEs managed by regulatory agencies (law enforcement) can send, receive, and process UAV control messages including required control information via a direct communication interface between UEs. Examples of scenarios using UAV control messages that can be operated according to various embodiments of the present disclosure include UE identifier broadcast control and collision detection and collision avoidance control, as shown in Table 1 below. However, the present disclosure is not limited thereto.

[0049] Table 1

[0050]

[0051] According to various embodiments of the present disclosure, the UAV control message may include a remote UE identity (used when the UE identity of unmanned mobility is remotely transmitted), a remote UE identity request (used when a request for transmitting the UE identity of unmanned mobility is remotely initiated), a remote UE positioning information (used when the location information of unmanned mobility is remotely transmitted), a remote UE positioning request (used when the location information of unmanned mobility is remotely transmitted), a remote UE path information (used when the moving path of unmanned mobility is remotely transmitted), a remote UE path request (used when a request for the moving path of unmanned mobility is remotely initiated), and a detect and avoid (DAA) control (used to notify the detection of a collision of unmanned mobility or an indication to avoid a collision), and may be transmitted through a PC5 interface.

[0052] As an embodiment, the unmanned vehicle service message including the UE identifier, that is, the removal UE identification of the unmanned vehicle, may include the following Table 2. However, the present disclosure is not limited thereto.

[0053] Table 2

[0054]

[0055] The unmanned vehicles used in the present disclosure may include all of unmanned aerial vehicles and urban air mobility. Of course, unmanned vehicles are not limited to this example and may include all types of vehicles without people on board as well as unmanned aerial vehicles and urban air mobility.

[0056] A method performed by a UE in a wireless communication system may include: an operation of determining whether transmission or reception of a UAV (Unmanned Aerial Vehicle) service message or a UAM (Urban Air Mobility) service message using U2X communication based on a PC5 interface is authenticated; an operation of determining a TX profile mapped to transmission or reception of a service message through U2X communication based on a PC5 interface; an operation of determining radio transmission parameters corresponding to the TX profile; an operation of performing transmission or reception by using the radio transmission parameters corresponding to the TX profile; and an operation of transmitting a destination layer 2 identifier mapped to a service identifier of the service message, PC5 RAT information mapped to the service identifier of the service message, and TX profile information mapped to the service identifier of the service message from a higher layer (upper layer) of the UE to an AS layer of the UE.

[0057] Figure 1 A scenario of supporting unmanned vehicle service messages in a wireless communication system according to an embodiment of the present disclosure is shown.

[0058] refer to Figure 1 UE 1 101 and UE 2 102 may be UEs in a wireless communication system supporting unmanned vehicles. For example, UE 1 101 may be a UE managed by an organization that manages unmanned vehicles. UE 2 102 may be a UE installed on an unmanned vehicle. As another example, UE 1 101 and UE 2 102 may be UEs installed on an unmanned vehicle. UE 2 102 may broadcast (multicast or one-way unicast) a UAV control message 1 or a UAM control message 1 110 to UE 1 101 via a direct communication interface (e.g., PC5 or sidelink).

[0059] based on Figure 1 The following describes an example scenario in which UE 1 101 and UE 2 102 transmit and receive unmanned vehicle control signaling. UE 2 102 may transmit its own identification information to UE 1 101 using a direct communication interface (e.g., PC5 or sidelink) to identify information related to operating the unmanned vehicle (authentication information, user registration information, etc.). UE 1 101 may be a UE that manages the unmanned vehicle (e.g., a UE managed by an organization that regulates unmanned vehicles). UE 2 102 may be a UE installed in the unmanned vehicle. For example, UE 2 102's identification information may be included in a UAV control message 1 or a UAM control message 1 110 transmitted by UE 2 102 to UE 1 101.

[0060] Figure 2 A scenario of supporting unmanned vehicle service messages in a wireless communication system according to an embodiment of the present disclosure is shown.

[0061] refer to Figure 2 UE 1 201 and UE 2 202 may be UEs in a wireless communication system supporting unmanned vehicles. For example, UE 1 201 may be a UE managed by an organization that manages unmanned vehicles. UE 2 202 may be a UE installed in an unmanned vehicle. For another example, UE 1 201 and UE 2 202 may be UEs installed in an unmanned vehicle.

[0062] According to an embodiment of the present disclosure, UE 1 201 and UE 2 202 may broadcast (multicast or one-way / two-way unicast) UAV control messages through a direct communication interface (eg, PC5 or sidelink).

[0063] based on Figure 2 The following describes an example scenario in which UE 1 201 and UE 2 202 transmit and receive unmanned mobility control signaling. UE 1 201, managed by an organization that manages unmanned vehicles, can use a direct communication interface (e.g., PC5 or sidelink) to transmit a UAV (or UAM) control message 2 210 requesting that identification information be transmitted to UE 2 202, mounted on the unmanned vehicle, in order to identify information (authentication information, user registration information, etc.) on the unmanned vehicle operated by the organization that manages unmanned vehicles. UE 2 202 can then use the direct communication interface to transmit a UAV (or UAM) control message 3 220 including its own identification information to UE 1 202.

[0064] In addition, according to an embodiment of the present disclosure, at least one of a UAV control message 2 210 and a UAV control message 3 220 or a combination thereof may be transmitted and received between UE 1 201 and UE 2 202 to request stopping of flight or provide information on a flight segment.

[0065] When based on Figure 1 and Figure 2 In the embodiment, when UE 1 101 or 201 and UE 2 102 or 202 are both UEs installed on unmanned vehicles, the UAV control messages sent and received by UE 1 and UE 2 may correspond to signaling including the UE's motion path, position (e.g., 3D position information), etc., or signaling for establishing a direct communication connection to exchange messages including the UE's motion path, position (e.g., 3D position information), etc. and configure a direct communication connection session.

[0066] When based on Figure 1 and Figure 2In an embodiment, when UE 1 and UE 2 transmit and receive UAV control messages using U2X communication over a PC5 interface, the PC5 interface may correspond to a PC5 interface over an LTE RAT or a PC5 interface over an NR RAT. Therefore, UE 1 and UE 2 should be aware of whether UAV control messages can be transmitted and received using U2X communication over a PC5 interface, and whether messages can be transmitted and received using a PC5 interface over an LTE RAT or a PC5 interface over an NR RAT when messages can be transmitted and received using U2X communication over a PC5 interface. Such information may be defined as a TX profile, i.e., a wireless transmission profile that can be applied to UE 1 and UE 2 to transmit and receive UAV control messages using U2X communication.

[0067] The TX profiles applied to UAV control messages should be synchronized to allow UE 1 and UE 2 to transmit and receive UAV control messages using U2X communication. That is, when transmitting and receiving UAV control messages, one UE can correctly receive the UAV control message sent by the other UE only when the same TX profile is applied. If UE 1 and UE 2 are not synchronized in the TX profiles applied to transmit and receive UAV control messages using U2X communication, one UE cannot correctly receive the UAV control message sent by the other UE. That is, when a different TX profile is applied, one UE cannot correctly receive the UAV control message sent by the other UE. Therefore, a method for configuring and synchronizing the TX profiles used for U2X communication may be required to allow UEs that will transmit and receive UAV control messages to use the same TX profile. In particular, since a unicast link for transmitting and receiving UAV control messages between UEs is not configured, a TX profile for U2X communication may be used when wireless transmission configuration information indicating how to transmit and receive UAV control messages cannot be exchanged. For example, when the UAV control message is transmitted in a multicast type or a broadcast type or is transmitted before a unicast link is configured, the TX profile for U2X communication can be used to synchronize wireless transmission configuration information between the transmitting UE and the receiving UE.

[0068] As an embodiment of the present disclosure, the policy in Table 3 below may be configured in the UE to allow the UE to send or receive UAM service messages or UAV service messages according to U2X communication based on the PC5 interface. However, the present disclosure is not limited thereto.

[0071]

[0072] As an embodiment of the present disclosure, a TX profile (i.e., a wireless transmission profile that can be applied to send and receive UAV control messages using U2X communication) can be defined separately from a TX profile defined for V2X communication based on the PC5 interface or proximity service (ProSe) communication based on the PC5 interface.

[0073] As an embodiment of the present disclosure, a TX profile that can be applied to sending and receiving UAV service messages using U2X communication and a TX profile that can be applied to sending and receiving UAM service messages using U2X communication can be defined identically or separately.

[0089] As an embodiment of the present disclosure, an example of a TX profile that can be applied to transmit and receive a UAV control message using U2X communication may include the following Table 6. However, the present disclosure is not limited thereto.

[0090] The embodiment of Table 6 is an example of a case where TX profile mapping when LTE PC5-based U2X communication is used to serve a UAV (or UAM) service identifier and TX profile mapping when NR PC5-based U2X communication is used to serve a UAV (or UAM) service identifier are separately configured.

When the UAV (or UAM) service message is authenticated, the UE may transmit the UAV (or UAM) service message, and the authentication information may include Table 3.

[0111] In operation 320, the UE may collect transmission-related information corresponding to the UAV (or UAM) service message generated in operation 310.

[0115] Figure 4 An operation of a UE processing a radio transmission profile for transmitting a service message in a wireless communication system according to an embodiment of the present disclosure is illustrated.

[0116] refer to Figure 4 In operation 410, when a UAV (or UAM) service message (e.g., a UAV UE ID or UAM UE ID broadcast) and a UAV (or UAM) service message are transmitted, the UE may obtain information to be referenced from a higher layer (upper layer) for selecting radio transmission parameters to be configured. In operation 410, an example of the information referenced by the UE may include Table 9. However, the present disclosure is not limited thereto.

Figure 5 illustrates the operation of the higher layers (upper layers) of the UE, and Figure 6 The diagram illustrates the operation of the AS layer of the UE.

[0120] Figure 5 An operation of a UE processing a radio transmission profile for receiving a service message in a wireless communication system according to an embodiment of the present disclosure is illustrated.

[0121] refer to Figure 5 , the UE may identify whether the UE is authenticated to receive the UAV (or UAM) service message. The authentication information of the UAV (or UAM) service message may include the information in Table 3. However, the present disclosure is not limited thereto.

[0122] In operation 520, the UE may identify information required to receive a UAV (or UAM) service message. The information required to receive the service message in operation 520 may include a UAV (or UAM) service identifier mapped to the UAV (or UAM) service message, a PC5 RAT mapped to the UAV (or UAM) service message, and TX profile information mapped to the UAV (or UAM) service message.

[0123] A UE can identify destination Layer 2 ID information for receiving UAV (or UAM) service messages via PC5-based U2X communication. For example, a destination Layer 2 ID corresponding to a UAV UE ID or UAM UE ID broadcast service can be configured in the UE. This information can be used to determine whether the destination Layer 2 ID of a message received from the sending UE matches the destination Layer 2 ID configured in the UAV (or UAM) service message corresponding to the received message.

[0124] In operation 530, the UE may transmit information regarding at least one of PC5 QoS (PQFI for NR, PPPP / PPPR for LTE), a TX profile, and a destination Layer 2 ID for receiving U2X communication messages, or a combination thereof, to the AS layer of the UE. For example, the information transmitted to the AS layer in operation 530 may include Table 9. However, the present disclosure is not limited thereto.

[0125] Figure 6 An operation of a UE processing a radio transmission profile for receiving a service message in a wireless communication system according to an embodiment of the present disclosure is illustrated.

[0126] refer to Figure 6 In operation 610, the UE may obtain information required for receiving a UAV (or UAM) service message from a higher layer (upper layer) of the UE.

[0127] In operation 620 , the UE may configure radio transmission parameters for receiving a UAV (or UAM) service message in operation 620 based on the information acquired in operation 610 .

[0128] The UE may receive TX profile information corresponding to the destination Layer 2 ID corresponding to the UAV (or UAM) service message from a higher layer (upper layer). Thereafter, when receiving and processing a UAV (or UAM) service message sent using U2X communication, the UE may receive and process the UAV (or UAM) service message based on PC5 QoS and the TX profile corresponding to the destination Layer 2 ID. For example, to receive and process a UAM UE ID or UAV UE ID broadcast service message, the UE may apply radio transmission parameters corresponding to the TX profile configured for the UAM UE ID or UAV UE ID broadcast service.

[0129] In operation 630, the UE may receive a transport block including a UAV (or UAM) service message. In operation 630, upon receiving the transport block, the UE may apply a radio transmission parameter corresponding to the TX profile.

[0130] In operation 640, the UE may determine whether the destination Layer 2 ID of the received message matches the destination Layer 2 ID configured in the UAV (or UAM) service message corresponding to the received message. That is, the UE may determine whether the destination of the UAV (or UAM) service message included in the received transport block is the UE. The UE's operation in operation 640 may be handled by the UE's higher layers (upper layers). For example, if the UE's AS layer, which receives the transport block including the UAV (or UAM) service message, only knows some information about the destination Layer 2 ID of the UAV (or UAM) service message and therefore has limitations in handling destination address mapping in operation 630, the UE's higher layers (upper layers) may also perform an operation to identify whether the destination address is mapped.
