[0033] In the following description, "when, if, or in the case of" can be replaced with "based on".

[0035] In this disclosure, higher-layer parameters can be parameters configured, pre-configured, or predefined for the UE.

[0038] The technologies proposed in this disclosure can be implemented as 6G wireless technologies and can be applied to various 6G systems. 6G systems can possess key features such as eMBB (enhanced Mobile Broadband), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), artificial intelligence (AI) integrated communication, tactile internet, high throughput, high network capacity, high energy efficiency, low backhaul and access network congestion, and enhanced data security.

[0039] Figure 1 A communication structure that can be provided in a 6G system according to one embodiment of the present disclosure is shown. Figure 1 The implementation methods can be combined with various implementation methods of this disclosure.

[0040] New network features in 6G may include: - Satellite Integrated Network - Connecting Intelligence: Unlike previous generations of wireless communication systems, 6G is revolutionary, and wireless evolution will shift from "connecting everything" to "connecting intelligence." AI can be applied to every step of the communication process (or every step of signal processing as described below).

[0041] - Seamless integration of wireless information and power transfer

[0042] - Ubiquitous Hyper-3D Connectivity: Hyper-3D connectivity will be created in ubiquitous 6G for access to drones, networks of very low Earth orbit satellites, and core network functions.

[0043] Among the new network features of 6G mentioned above, some general requirements can be as follows.

[0044] - Small community network

[0045] - Ultra-dense heterogeneous networks

[0046] - High-capacity return

[0047] - Radar technology integrated with mobile technology: High-precision positioning (or location-based services) achieved through communication is one of the functions of 6G wireless communication systems. Therefore, radar systems will be integrated with 6G networks.

[0048] - Softwareization and Virtualization

[0049] The key implementation technologies of 6G systems are described below.

[0050] Artificial Intelligence: Introducing AI into telecommunications can simplify and improve real-time data transmission. AI can use numerous analyses to determine how to perform complex target operations, meaning it can improve efficiency and reduce processing latency. Time-consuming tasks such as handover, network selection, and resource scheduling can be completed instantly using AI. AI can also play a significant role in M2M, machine-to-human, and human-to-machine communications. Furthermore, AI can enable rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, smart structures, smart networks, smart devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0051] -THz communication (terahertz communication): Data rates can be increased by increasing bandwidth. This can be achieved by using sub-THz communication with wide bandwidth and applying advanced massive MIMO technology. THz waves (also known as sub-millimeter radiation) refer to the frequency band between 0.1 THz and 10 THz, where the corresponding wavelengths are typically in the range of 0.03 mm to 3 mm. The 100 GHz-300 GHz frequency band range (sub-THz band) is considered the main part of the THz frequency band used for cellular communication. Adding sub-THz bands to the millimeter wave band increases the capacity of 6G cellular communication. The 300 GHz-3 THz band in the defined THz frequency band is in the far-infrared (IR) band. The 300 GHz-3 THz band is part of the optical band, but it is on the boundary of the optical band, just behind the RF band. Therefore, the 300 GHz-3 THz band exhibits similarity to RF. Figure 2 The electromagnetic spectrum according to one embodiment of the present disclosure is shown. Figure 2The implementation methods can be combined with various embodiments of this disclosure. Key characteristics of THz communication include (i) a wide range of available bandwidth supporting very high data rates, and (ii) high path loss at high frequencies (for which highly directional antennas are indispensable). The narrow beamwidth generated by highly directional antennas reduces interference. The small wavelength of THz signals allows a greater number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array techniques that can overcome range limitations.

[0065] - Unmanned Aerial Vehicles (UAVs): UAVs, or unmanned aerial vehicles, will be a crucial component of 6G wireless communication. In most cases, UAV technology will be used to provide high-speed data wireless connectivity. Base station (BS) entities are mounted on UAVs to provide cellular connectivity. UAVs possess specific characteristics not found in fixed BS infrastructure (e.g., ease of deployment, strong line-of-sight links, and degrees of freedom of controlled mobility). During emergencies such as natural disasters, the deployment of terrestrial communication infrastructure is economically infeasible and sometimes unable to provide service in volatile environments. UAVs can easily handle these situations. UAVs will be a new paradigm in wireless communication. This technology contributes to the three fundamental requirements of wireless networks: eMBB, URLLC, and mMTC. UAVs can also support many other purposes such as enhanced network connectivity, fire detection, disaster emergency services, security and surveillance, pollution monitoring, parking monitoring, accident monitoring, and more. Therefore, UAV technology is considered one of the most important technologies for 6G communication.

[0066] - Advanced Air Mobility (AAM): AAM is a higher-level concept than Urban Air Mobility (UAM). UAM refers to air transportation that can be used in urban centers, while AAM can refer to transportation that includes movement between urban centers and regional bases.

[0067] - Autonomous Driving (Autonomous Driving, Self-Driving): Vehicle-to-everything (V2X) (a key element in building the infrastructure for autonomous driving) is a technology that allows vehicles to communicate with various elements on the road and share information to perform autonomous driving (e.g., vehicle-to-vehicle (V2V) wireless communication and vehicle-to-infrastructure (V2I) wireless communication). To maximize the performance of autonomous driving and ensure high safety, high transmission speeds and low latency technologies are necessary. Furthermore, in the future, autonomous driving will go beyond simply delivering warnings or guidance messages to the driver to proactively intervene in vehicle operation and directly control the vehicle in dangerous situations; therefore, the amount of information that needs to be sent and received will be substantial, and 6G is expected to maximize autonomous driving with faster transmission speeds and lower latency than 5G.

[0068] Meanwhile, although the infrastructure capable of V2X communication (e.g., roadside units (RSUs), servers, etc.) and road users (e.g., vehicles, pedestrians, etc.) are gradually emerging, V2X adoption is still in its early stages and appears to be a long process until a cooperative intelligent transportation system (C-ITS) environment consisting of fully networked (or equipped) road users and infrastructure is established. Until then, V2X services will be provided and used in a mixed manner, with networked road users and infrastructure alongside unnetworked (or unequipped) road users and infrastructure lacking V2X communication capabilities. To this end, solutions are currently being developed to identify unnetworked road users existing between networked infrastructure and road users and to integrate these unnetworked road users into V2X services.

[0069] Figure 3 An example is given of an infrastructure device at an intersection that detects non-networked road users and transmits this information to networked road users.

[0070] For example, such as Figure 3As shown, when a networked RSU and road users (Vulnerable Road Users (VRUs) #2, VRU #3, Vehicle #2, Vehicle #3) are present at an intersection, and a non-networked road user (VRU #1, Vehicle #1) is also present, the RSU can detect the non-networked road user (VRU #1, Vehicle #1) and provide its status information to the networked road users (VRUs #2, VRU #3, Vehicle #2, Vehicle #3). Additionally, for example, networked road users can also detect non-networked road users using installed sensors and can send proxy messages. Typically, for example, there can be services and messages (e.g., SDSM (Sensor Data Sharing Message), CPM (Collective Perception Message)) that integrate objects detected by sensors into a single message and send that single message. Additionally, for example, there can be messages (e.g., SBSM (Proxy Basic Safety Message)) that are generated and sent as a proxy / alternative to the status message of a single non-networked road user, currently being standardized by SAE. For example, the services and messages mentioned above can be represented as proxy messages, and these messages (proxy messages) can refer to a UE with communication capabilities (e.g., vehicle / VRU / RSU / server, etc.) generating and sending status messages (e.g., cooperative awareness messages (CAM), basic safety messages (BSM), VRU awareness messages (VAM), personal safety messages (PSM)) on behalf of a road user who does not have V2X communication equipment (not equipped), is not connected (not connected), or has V2X communication capabilities but is currently unable to send its status messages (disabled / unavailable).

[0071] For example, in the current standard document for SBSM (SAE J2945 / 8), which is being standardized, a vehicle can generate and send a Basic Safety Message (BSM) for a non-connected road user. In this scenario, when a non-connected road user is detected by multiple connected road users, the standard document applies rules to prevent the duplicate transmission of information messages for road users that detect the same object. For example, as a method for limiting the repeated transmission of proxy status messages (e.g., SBSMs) as described in this document, if the same object detected by multiple connected vehicles (e.g., device A, device B, etc.) or identified as the same object (because the object exists within a diameter of 1.5m) is a connected road user and that connected road user sends its own status message (e.g., BSM), or if the detected object is a non-connected road user and a message (e.g., SBSM) including information about that non-connected road user is sent by a connected road user (e.g., device A) and that message is received by another connected road user (e.g., device B), then the connected road user (e.g., device B) may postpone and / or stop transmission for a specific duration (e.g., 5 seconds in the case of J2945 / 8) even if it detects the same non-connected road user. For example, this method can allow a network infrastructure or road user that was previously transmitting proxy messages to have priority in transmitting messages.

[0072] Meanwhile, the above-mentioned content is described in the current standard documents related to SBSM as follows.

[0073] - Limit SBSM duplicate transmissions

[0074] If the host vehicle (HV) receives an SBSM indicating an object within a 1.5m diameter range of the location of a vehicle already detected by the HV, the HV may perform the following actions.

[0075] For example, the transmission of the SBSM for a detected vehicle can be delayed by 5 seconds. For example, the 5-second timer can be reset whenever an SBSM representing a detected vehicle is received.

[0076] For example, the transmission of an SBSM representing a detected vehicle can be stopped immediately for 5 seconds. Alternatively, the 5-second timer can be reset whenever an SBSM representing a detected vehicle is received.

[0077] Meanwhile, when multiple transmitters detect / identify / analyze the same object or information and send it to surrounding UEs, the aforementioned conventional message sending method can assign a sending priority to the transmitter that most recently sent the same information to prevent duplicate transmission of the same information. This is the simplest method to prevent duplicate transmission, but it may fail to consider the capabilities of sending candidates capable of sending the same information in every situation. For example, when multiple networked road users (e.g., sending candidates) detect a single non-networked road user and identify a single transmitter to avoid duplicate transmission of proxy messages (e.g., CPM, SDSM, SBSM, etc.) that include information about non-networked road users, if some transmitters have already sent proxy messages for non-networked road users to their surroundings—that is, the sending candidates have already received the message—the UE that has already sent the proxy message has priority to send proxy messages for non-networked road users and can continue to send proxy messages, while other candidates cannot. In this situation, for example, due to the failure to consider the relationship between non-networked road users and sending candidates and / or the situation and capabilities of all sending candidates, there may be limitations in providing status information of non-networked road users to networked road users.

[0078] Figure 4 A conventional method is shown for sending agent messages for multiple connected vehicles that detect a single non-connected vehicle.

[0079] For example, such as Figure 4As shown, when two connected vehicles (HV A 420 and HV B 430) detect a non-connected vehicle 410, and HV A 420 is already sending a proxy message (e.g., SBSM) 440 containing information about the non-connected vehicle, according to the conventional sending method, HV B 430 must postpone or stop sending the non-connected vehicle's proxy message within 5 seconds. However, for example, when considering the relationship and circumstances (e.g., position, relative speed, angle, or driving lane) between the non-connected vehicle and connected vehicles capable of sending the non-connected vehicle's status information, HV B 430, which is in the same lane and driving in the same direction as the non-connected vehicle, can detect information related to the non-connected vehicle 410 more effectively and can generate and send proxy messages for a longer period of time compared to HV A 420, which has priority by sending the non-connected vehicle's proxy message 440. For example, if HV A 420 passes by non-connected vehicle 410 after 1 second and can no longer detect the non-connected vehicle or generate and send proxy messages, then because HV B 430 cannot perform transmission within 5 seconds using the current method, the information of non-connected vehicle 410 may not be provided to other connected road users for 4 seconds. That is, for example, there may be gaps in the sharing of information related to non-connected vehicles, and other connected road users may have difficulty identifying non-connected road users, which may pose a threat to traffic safety.

[0080] Furthermore, for example, when propagating information, the propagation area can be expanded through multi-hop and / or relay transmission. A potential problem arises when multi-hop and / or relay transmission is performed from a single information source, allowing the same UE to receive duplicate information from multiple relay UEs after several hops / relays via multiple relays. Even in these cases, wireless communication resources can be excessively consumed.

[0081] This disclosure proposes a method for configuring transmission priority by considering the state and environment of transmission candidates (including the correlation between the information to be transmitted and the transmission candidates) to avoid duplicate transmissions when multiple transmitters are capable of transmitting the same information, as well as an apparatus supporting the method. For example, "same information" can refer to the source / origin of information, such as information obtained from the same source, information in the same context, or information detected from the same object. Additionally, for example, the priority of the message transmitter can be configured based on sensing / identification / analysis capabilities, communication / transmission capabilities, or tracking and transmission persistence capabilities related to the information the transmission candidate wants to transmit. Furthermore, for example, when multiple networked infrastructures or road users detect proxy messages from non-networked road users and want to send the information from the non-networked road users to surrounding networked road users, in the transmission method for avoiding duplicate transmissions, the transmitter can be selected by calculating the tracking and transmission persistence of multiple transmission candidates. For example, tracking and transmission persistence can be represented by quantitative figures and can be calculated differently for each transmitter, taking into account the relationship and / or circumstances between the transmitter and the non-networked road users.

[0082] In this disclosure, when multiple transmitters are capable of sending / transmitting the same source of information (e.g., objects, events, information, etc.), a method for configuring transmission priority is proposed in the method for selecting a single and / or specific transmitter / sender to avoid duplicate transmissions, taking into account the state and environment of the transmission candidates (including the correlation between the information to be sent and the transmission candidates). In this case, for example, the source of the information may include information obtained by sensors (e.g., information of non-networked objects and / or objects that do not send information messages themselves) or road event information (e.g., road construction information, accident information, traffic congestion information, or weather information), etc. Additionally, for example, the transmitter may be an information generator and / or sender (e.g., a UE that receives information from another source and sends that information). The elements in this disclosure that define the relationship between the source of the information and the transmission / forwarding candidates can configure the priority of the message transmitter based on at least one of the following elements: sensing / identification / analysis capabilities, communication / transmission capabilities, or tracking and transmission persistence capabilities of the information to be sent. For example, these elements may include sensor capabilities, sensor data processing capabilities, communication capabilities (e.g., the strength of communication signals), distance from the information source, relative speed, direction of movement, direction of detection, trackable time, transmission duration, etc.

[0083] For example, when considering services that share information about objects / road users detected by sensors, wireless communication resources can be saved by selecting a single or specific transmitter from among multiple transmission candidates that detect the same object, thus preventing the duplicate transmission of the same information. For example, when selecting a single or specific transmitter, a quantity / specific value (e.g., transmission persistence level / value) used to configure priority can be calculated and exchanged as a comparison criterion. For example, when multiple networked road users or infrastructure (e.g., servers / RSUs) detect information about non-networked road users detected by sensors and want to transmit / provide this information to / from surrounding networked road users, in a transmission method to avoid duplicate transmissions, a single transmitter can be selected by calculating and comparing specific values ​​of multiple transmission candidates, while considering the relationship and circumstances (e.g., tracking and transmission persistence) between the transmission candidate and the non-networked road user (e.g., the source of the information). For example, the distance, relative speed, difference in heading direction, difference between the heading direction and the sensor's detection direction, message transmission history for the same object (e.g., number of transmissions), and type of transmission candidate (e.g., RSU, vehicle, bicycle, pedestrian) between the detected non-networked road user and each transmission candidate can be used as specific values ​​for configuring priority. For example, these specific values ​​for configuring priority can be transmitted to surrounding networked infrastructure and / or road users by being included in the agent message of the non-networked road user, and other transmission candidates receiving this specific value can determine whether to transmit by comparing it with their own specific value. For example, when a networked vehicle detects an object using its sensors and does not receive a message containing information about the detected object, it can transmit the object information along with specific values ​​for configuring its own priority. For example, refer to the above. Figure 4 If networked road users ( Figure 4 HV A 420 in the middle is sending to non-networked road users ( Figure 4 Information about non-connected vehicles (410) and messages with specific values ​​(e.g., SBSM) Figure 4 If the proxy message 440 sent from HVA is detected, then the same non-networked road user ( Figure 4 Another connected road user (410) of the non-connected road user ( Figure 4 The HV B 430 in the middle can transmit agent messages to non-networked road users by means of a transmitter that has already sent the message ( Figure 4 The specific value of HVA 420 in the data is related to itself. Figure 4 The specific value of HV B 430 in the code is compared to determine whether to send. For example, if it is itself ( Figure 4A specific value of HV B 430 in the data is higher (or lower) than that of the transmitter that has already sent the data. Figure 4 A specific value in HV A 420 can stop transmission; conversely, if it is lower (or higher) than the value of the transmitter that has already transmitted (…), transmission can be stopped. Figure 4 A specific value in HV A 420 can be used to perform transmission. For example, a specific value used to configure the priority of the transmission candidate (x) can be calculated as follows. For example, this specific value can be interpreted as being replaced by the transmission persistence level (TPL), and the function used to calculate the TPL of the transmission candidate (x) can be shown in Functional Equation 1 below.

[0084] [Function Equation 1]

[0085] TPL = a × Distance + b × Relative Speed ​​+ c × Heading Difference + d × Angle Between Heading and Detection Direction + e / (Message Counter + 1) + f × Type of Sending Candidate

[0086] For example, a, b, c, d, e, and f in Equation 1 above are coefficients that can be configured in various ways for each service or message. Additionally, for example, distance can refer to the distance between the information source and the sending candidate, relative speed can refer to the relative speed between the information source and the sending candidate, and heading difference can refer to the difference between the direction of movement of the information source and the direction of movement of the sending candidate. For example, if among multiple sending candidates there is a sending candidate that is close to the detected object and moving in the same direction at a similar speed, that sending candidate can be selected as a single sender with high priority. For example, the angle between the heading and the detection direction can refer to the difference between the direction in which the sending candidate senses / observes the information source and the direction it is moving. For example, if the information source is a non-connected vehicle, this value can be calculated as low when the sending candidate is traveling in the same lane and / or path, or as high when the sending candidate is traveling in different lanes and / or paths (e.g., the non-connected vehicle is turning left and the sending candidate is turning right). For example, a message counter can refer to the number of times a message has been sent (e.g., MSGCount) to take into account the previous sending history of messages to the information source. That is, among sending candidates in similar environments, those with a previous sending history can send information continuously. For example, the type of sending candidate can refer to the type of sending candidate, and the type of sending candidate can be configured with a specific value for each type as an element that can take into account the characteristics of the transmitter. For example, if a superior infrastructure (e.g., a server / RSU) in terms of sensor performance, communication capabilities, etc., is a sending candidate, a bonus can be assigned to a specific value used to configure the sending priority. For example, by configuring the infrastructure value to "1", the vehicle value to "5", and the pedestrian value to "9", the infrastructure (e.g., the server / RSU) can be given a higher sending priority (with a lower value) than the vehicle or pedestrian. Additionally, for example, the vehicle can be given a higher sending priority (with a lower value) than the pedestrian. For example, the above description of selecting a single transmitter from multiple transmission candidates for a single object detected by a sensor is one example, and the contents of this disclosure can be applied when it is necessary to limit or control duplicate transmissions between other V2X services or when it is necessary to select a single or specific transmitter. For example, multi-hop or relaying can be used in V2X services to extend information propagation or communication range. In such cases, for example, this can lead to duplicate transmissions of the same information through multiple relay UEs. In such cases, for example, priority configuration can be performed to select a single or specific transmitter / sender from multiple transmission / relay candidates by considering the relationship between the information source and the transmission / forwarding candidates as described in this disclosure, as well as other relevant factors.

[0087] The method presented in this disclosure can be implemented in conjunction with the SBSM retransmission restriction method for proxy V2V (vehicle-to-vehicle) secure communication services in the content of the SAE standard (J2945 / 8) which is currently being standardized, as described in the following embodiments.

[0088] Figure 5 A method for transmitting proxy messages by a single transmitter at a road intersection to detect non-networked vehicles, based on an embodiment of this disclosure, is shown. Figure 5 The implementation methods can be combined with various implementation methods of this disclosure.

[0089] Reference Figure 5 When a connected vehicle (HVA) 520, which detects a non-connected vehicle 510, attempts to send a message (e.g., SBSM) 521 containing information about the non-connected vehicle (e.g., location, speed, direction, etc.), it can check whether a message containing information about the same vehicle or identified as the same vehicle exists. For example, if no received message exists, HVA 520 can calculate the Transmission Persistence Level (TPL) as described by way of example in this disclosure and send it along with the information about the non-connected vehicle. For example, the Transmission Persistence Level (TPL) for the non-connected vehicle 510 by HVA 520 can be calculated as follows.

[0090] f(HV A, t0) = 0.5 × 20[m] + 0.5 × 1[m / s] + 0.03 × 0[deg] + 0.03 ×30[deg] + 0.01 / (0+1) + 1 × 5 = 16.41

[0091] Figure 6 A method for selecting a single transmitter among multiple transmitters for detecting non-networked vehicles at a road intersection, based on an embodiment of the present disclosure, is shown. Figure 6 The implementation methods can be combined with various implementation methods of this disclosure.

[0092] Reference Figure 6 , Figure 6 The examples shown above can be the situations described above. Figure 5The scenario illustrated (e.g., time t0) is followed by a subsequent scenario (e.g., time t1). For example, a connected vehicle (HVA 620) that detects a non-connected vehicle 610 can calculate its own (HVA 620) TPL and send it along with information about the non-connected vehicle to surrounding road users. For example, in this scenario, a connected vehicle (HVB 630) that detects a non-connected vehicle 610 can receive a proxy message (e.g., SBSM) and a transmission persistence level (TPL) 621 from a transmitter (HVA 620) that has already sent the message when entering the ramp. For example, before detecting a non-connected vehicle 610 and sending a proxy message for the non-connected vehicle, HVB 630 can calculate its own transmission persistence level (TPL) and determine whether to send it by comparing it with the TPL of a transmitter that has already sent the message (e.g., HVA 620). For example, at this time, the Transmission Persistence Level (TPL) of the connected vehicles (HV A 620, HV B 630) can be calculated as follows.

[0093] f(HV A, t1) = 0.5 × 20[m] + 0.5 × 1[m / s] + 0.03 × 0[deg] + 0.03 ×30[deg] + 0.01 / (1+1) + 1 × 5 = 16.45

[0094] f(HV B, t1) = 0.5 × 10[m] + 0.5 × 5[m / s] + 0.03 × 10[deg] + 0.03× 0[deg] + 0.01 / (0+1) + 1 × 5 = 12.81

[0095] In this scenario, for example, HV B 630 can check that its own Transmission Persistence Level (TPL) is lower than that of HVA 620, and can transmit the non-networked vehicle information message 631. For example, after receiving the non-networked vehicle information message (e.g., SBSM) and the Transmission Persistence Level (TPL) 631 from HV B 630, HVA 620 can check that its own Transmission Persistence Level (TPL) is higher than that of HV B 630, and then HVA 620 can stop transmitting the non-networked vehicle information message.

[0096] Figure 7 A method for detecting road construction information and transmitting it to surrounding road users, based on an embodiment of the present disclosure, is shown. Figure 7 The implementation methods can be combined with various implementation methods of this disclosure.

[0097] Reference Figure 7 For example, in a service that notifies road users of road information, this involves detecting road construction information and sending that information as a V2X message (e.g., Roadside Alert (RSA), Road Safety Message (RSM), Basic Safety Message (BSM) Part 2, Distributed Environmental Notification Message (DENM)) to nearby road users. Figure 7 In this context, when vehicle A730, vehicle B740, and RSU720 detect / identify road construction (710) and send a message to surrounding road users, a single transmitter can be selected to avoid duplicate transmissions. In such cases, for example, when a single transmitter is selected by calculating a specific value proposed in this disclosure for priority configuration, the Transmission Persistence Level (TPL) can be calculated as follows.

[0098] f(RSU, t0) = 0.5 × 10[m] + 0.5 × 0[m / s] + 0.03 × 0[deg] + 0.03 ×30[deg] + 0.01 / (0+1) + 1 × 1 = 6.91

[0099] f(Vehicle A, t0) = 0.5 × 10[m] + 0.5 × 5[m / s] + 0.03 × 0[deg] + 0.03× 30[deg] + 0.01 / (0+1) + 1 × 5 = 13.41

[0100] f(vehicle B, t0) = 0.5 × 20[m] + 0.5 × 5[m / s] + 0.03 × 0[deg] + 0.03× 0[deg] + 0.01 / (0+1) + 1 × 5 = 17.51

[0101] In the example calculation above, the type of the sending candidate (e.g., RSU=1, vehicle=5) can be reflected in the value of the Sending Persistence Level (TPL), which allows RSU to be selected as a single sender.

[0102] Figure 8 An example of a method for transmitting road construction information to surrounding road users using multi-hops is provided based on an embodiment of the present disclosure. Figure 8 The implementation methods can be combined with various implementation methods of this disclosure.

[0103] Reference Figure 8When messages (e.g., DENM / RSA) sent by RSU 810 are transmitted in a multi-hop manner to surrounding road users (vehicle A 821, vehicle B 822) to extend the propagation range, considering wireless communication resources, it may be necessary to select specific transmitters rather than all transmitters. For example, as Figure 8 As shown, after RSU 810 sends information (e.g., DENM / RSA) to road users (vehicle A 821, vehicle B 822) within the communication range, the road users who receive the information (vehicle A 821, vehicle B 822) can send the same information to surrounding road users (e.g., vehicle A 821 sends it to vehicle C 823 and vehicle E 825, vehicle B 822 sends it to vehicle C 823 and vehicle D 824) to extend the information propagation range. In this situation, for example, when a specific or single relay must be selected due to constraints in wireless communication resources, a specific value for selecting the transmitter can be calculated by considering the relationship between the information source and the relay as presented in this disclosure and the circumstances. For example, when applying the implementation of the Transmission Persistence Level (TPL) described above, vehicle B 822 can be assigned a transmission priority, and vehicles C 823 and D 824 can receive the same information through information propagation. For example, this is a more efficient and continuous information transmission than selecting vehicle A 821 as the transmitter / sender and sending information to vehicle C 823 and vehicle E 825.

[0104] Figure 9 A flowchart illustrating an embodiment of this disclosure for determining transmission priority based on TPL to prevent duplicate transmissions is shown. Figure 9 The implementation methods can be combined with various implementation methods of this disclosure.

[0105] Reference Figure 9 In step S910, multiple sending candidates can evaluate the Transmission Durability Level (TPL) by considering the relationship and circumstances between the information source and each sending candidate, in order to configure the priority for transmitter selection. In step S920, if each of the multiple sending candidates receives a message about the information source from other sending candidates, each of the multiple sending candidates can compare its own Transmission Durability Level (TPL) with the TPLs of the other sending candidates. In step S930, after comparing the Transmission Durability Levels (TPLs) of the multiple sending candidates, each of the multiple sending candidates can determine whether to send the information message or stop sending.

[0106] Figure 10 A method for preventing duplicate transmission of agent messages based on a TPL, according to an embodiment of the present disclosure, is shown. Figure 10The implementation methods can be combined with various implementation methods of this disclosure.

[0107] Reference Figure 10UE 1 and UE 2 can be networked (or equipped with the function) UEs (e.g., road users or RSUs). In step S1010, UE 1 can detect objects (or situations) on the road, and UE 2 located around UE 1 can also detect objects (or situations) on the same road detected by UE 1. For example, objects on the same road detected by UE 1 and UE 2 can be non-networked (or unequipped) UEs (e.g., road users) (or situations on the same road detected by UE 1 and UE 2 can be road construction, traffic accidents, traffic congestion, weather, etc.). On the other hand, if the object detected by UE 1 and UE 2 is a non-networked UE, the object does not have the ability to send information related to itself to surrounding road users (e.g., UE 1 or UE 2), so UE 1 or UE 2 around the object can send information related to the object on behalf of the object. In step S1020, each of UE 1 and UE 2 can calculate a Transmission Persistence Level (TPL) value representing the correlation between the detected object and itself. For example, the TPL value can represent the tracking capability or persistent information transmission capability of each UE in UE 1 and UE 2 for a detected object. For example, even if UE 1 and UE 2 detect the same object, the sensor performance, data processing capability, communication performance, distance from the detected object, and direction of movement of UE 1 and UE 2 may differ. Therefore, the TPL value of UE 1 for the object calculated by UE 1 and the TPL value of UE 2 for the object calculated by UE 2 may be different from each other. For example, each UE in UE 1 and UE 2 can calculate the TPL value based on the function equation 1 described above. In step S1030, UE 2 can send a message including its own TPL value to UE 1, which is a peripheral transmission candidate. For example, the message including UE 2's TPL value may be a Proxy Basic Security Message (SBSM), which includes information related to the object detected by UE 2. In step S1040, UE 1 can determine that UE 1 and UE 2 have detected the same object based on the information included in the message received in step S1030 as described above. UE 1 can also compare its own TPL value calculated in step S1020 as described above with the TPL value of UE 2 included in the message received in step S1030 as described above, to prevent duplicate transmission of proxy messages for the object. For example, UE 1 can determine whether to send a new message containing information related to the detected object based on the comparison between UE 1's TPL value and UE 2's TPL value.That is, for example, if the message received by UE 1 from UE 2 that includes object-related information is a proxy message that includes object-related information at time t0, UE 1 can determine whether to send a proxy message that includes object-related information at time t1 after time t0 by comparing the TPL values. In step S1050, UE 1 can send a new message including object-related information to UE 2 based on the fact that UE 1's TPL value is less than UE 2's TPL value. In this case, for example, UE 1 can include UE 1's TPL value in the new message and send it to UE 2. That is, for example, UE 1 can determine that its tracking capability for the object or its persistence capability for sending information about the object is superior to UE 2's tracking capability or persistence capability for sending information based on the fact that UE 1's TPL value is less than UE 2's TPL value. Furthermore, UE 1 can determine that the priority associated with sending a proxy message that includes information related to the detected object is higher than the priority associated with UE 2's sending a proxy message that includes information related to the detected object. Therefore, UE 1 can send a new proxy message including UE 1's TPL value and information related to the detected object to UE 2. In step S1060, UE 2, having received the message from UE 1, can stop sending proxy messages including information related to the detected object. For example, UE 2 can determine that its own TPL value is greater than UE 1's TPL value based on the TPL value of UE 1 included in the message sent from UE 1 in step S1050 as described above. That is, for example, UE 2 can determine that its tracking capability for the object or its persistence capability for sending information about the object is not superior to UE 1's tracking capability or persistence capability for sending information based on the fact that UE 2's TPL value is greater than UE 1's TPL value. Furthermore, UE 2 can determine that the priority associated with sending proxy messages including information related to the detected object is lower than the priority associated with UE 1 sending proxy messages including information related to the detected object. Therefore, even if UE 2 is able to detect the object and analyze the information related to the object, it can stop sending proxy messages including information related to the object.

[0108] According to various embodiments of this disclosure, by configuring the priority of message transmitters based on tracking and transmission persistence, duplicate transmissions can be effectively prevented, and wireless communication resources can be used efficiently. Furthermore, for example, transmitters capable of effectively detecting / identifying / analyzing information to be transmitted and continuously transmitting information can be selected. For example, when generating and transmitting information by detecting moving objects using sensors, it is advantageous to use transmission candidates with excellent environments for object detection, as this provides high-quality information. In this case, for example, high-level information can be provided to surrounding UEs to improve traffic safety and flow efficiency. Additionally, for example, by selecting a single or specific transmitter to avoid duplicate transmissions, wireless communication resources can be used efficiently. Furthermore, for example, as an effect of the proxy message transmission method proposed in this disclosure, by continuously transmitting proxy messages including information about non-networked road users, the gaps between proxy messages can be minimized, and by continuously transmitting detailed information, surrounding networked infrastructure or road users can more efficiently identify non-networked road users. In this case, for example, the quality of V2X services can be improved, thereby improving traffic safety and efficiency.

[0109] Figure 11 A method for performing wireless communication by a first device based on an embodiment of the present disclosure is shown. Figure 11 The implementation methods can be combined with various implementation methods of this disclosure.

[0110] Reference Figure 11 In step S1110, the first device can detect an object. In step S1120, the first device can obtain a first Transmission Persistence Level (TPL) value associated with the object. In step S1130, the first device can receive a first message from the second device, the first message including a second TPL value associated with the object. In step S1140, the first device can determine whether to send a second message based on the first TPL value and the second TPL value, the second message including information related to the object.

[0111] For example, it can be determined whether to send a second message based on a comparison between a first TPL value and a second TPL value.

[0112] For example, a first TPL value can be obtained based on the correlation between the first device and the object. And, for example, a second TPL value can be obtained based on the correlation between the second device and the object.

[0113] For example, the first TPL value can be obtained based on the distance between the first device and the object.

[0114] For example, the first TPL value can be obtained based on the relative velocity between the first device and the object. That is, for example, the first TPL value can be obtained based on the relative velocity of the first device relative to the object.

[0115] For example, the first TPL value can be obtained based on the heading difference between the first device and the object. That is, for example, the first TPL value can be obtained based on the difference between the heading direction of the first device and the heading direction of the object.

[0116] For example, the first TPL value can be obtained based on the angle between the heading of the first device and the object and the detection direction. That is, for example, the first TPL value is obtained based on the angle between the heading direction of the first device and the detection direction relative to the object.

[0117] For example, the first TPL value can be obtained based on the message count of the first device. That is, for example, the first TPL value can be determined based on the number of messages related to the object that the first device has already sent before determining whether to send a second message.

[0118] For example, the first TPL value can be obtained based on the type of the first device.

[0119] For example, the first TPL value can be obtained by summing all of the following: (i) a value determined based on the distance between the first device and the object multiplied by a first coefficient, (ii) a value determined based on the relative velocity between the first device and the object multiplied by a second coefficient, (iii) a value determined based on the heading difference between the first device and the object multiplied by a third coefficient, (iv) a value determined based on the angle between the heading and the detection direction between the first device and the object multiplied by a fourth coefficient, (v) a value obtained by dividing a fifth coefficient by the sum of the message count of the first device and 1, and (vi) a value determined based on the type of the first device multiplied by a sixth coefficient.

[0120] For example, based on the fact that the first TPL value is less than the second TPL value, a second message including the first TPL value can be sent.

[0121] For example, if a second message based on a first TPL value less than the second TPL value is sent to the second device, the second device may be stopped from sending a third message containing information related to the object.

[0122] For example, if the first TPL value is greater than the second TPL value, the first device can be stopped from sending the second message.

[0123] The proposed method can be applied to apparatuses according to various embodiments of this disclosure. First, the processor 102 of the first apparatus 100 can detect an object. Furthermore, the processor 102 of the first apparatus 100 can obtain a first Transmission Persistence Level (TPL) value associated with the object. Furthermore, the processor 102 of the first apparatus 100 can control a transceiver 106 to receive a first message from a second apparatus, the first message including a second TPL value associated with the object. Furthermore, the processor 102 of the first apparatus 100 can determine whether to send a second message based on the first TPL value and the second TPL value, the second message including information related to the object.

For example, the instructions, upon execution, cause a first device to perform an operation, the operation including: detecting an object; obtaining a first transmission persistence level (TPL) value associated with the object; receiving a first message from a second device, the first message including a second TPL value associated with the object; and determining, based on the first TPL value and the second TPL value, whether to send a second message, the second message including information related to the object.

[0137] Figure 13 A communication system 1 based on an embodiment of the present disclosure is shown. Figure 13 The implementation methods can be combined with various implementation methods of this disclosure.

[0138] Reference Figure 13The communication system 1, which applies various embodiments of this disclosure, includes a wireless device, a base station (BS), and a network. Herein, a wireless device refers to a device that performs communication using a radio access technology (RAT) (e.g., 5G New RAT (NR) or Long Term Evolution (LTE)) and may be referred to as a communication / radio / 5G device. Wireless devices may include, but are not limited to, robots 100a, vehicles (100b-1, 100b-2), extended reality (XR) devices (100c), handheld devices 100d, home appliances 100e, Internet of Things (IoT) devices 100f, and artificial intelligence (AI) devices / servers 400. For example, a vehicle may include a vehicle with wireless communication capabilities, an autonomous vehicle, and a vehicle capable of performing vehicle-to-vehicle communication. Herein, a vehicle may include an unmanned aerial vehicle (UAV) (e.g., a drone). XR devices can include augmented reality (AR) / virtual reality (VR) / mixed reality (MR) devices and can take the form of head-up displays (HMDs), head-up displays (HUDs) installed in vehicles, televisions, smartphones, computers, wearable devices, home appliances, digital signage, vehicles, robots, etc. Handheld devices can include smartphones, smart tablets, wearable devices (e.g., smartwatches or smart glasses) and computers (e.g., laptops). Home appliances can include TVs, refrigerators, and washing machines. IoT devices can include sensors and smart meters. For example, the BS and network can be implemented as wireless devices, and a particular wireless device (200a) can operate as a BS / network node relative to other wireless devices.

[0139] In addition to LTE, NR, and 6G, the wireless communication technologies implemented in the wireless devices 100a to 100f of this disclosure may also include narrowband Internet of Things (IoT) for low-power communication. In this case, for example, NB-IoT technology may be an example of low-power wide-area network (LPWAN) technology and may be implemented as a standard such as LTE Cat NB1 and / or LTE Cat NB2, and is not limited to the aforementioned names. Alternatively or additionally, the wireless communication technologies implemented in the wireless devices 100a to 100f of this disclosure may perform communication based on LTE-M technology. In this case, as an example, LTE-M technology may be an example of LPWAN and may be referred to by various names including enhanced machine-type communication (eMTC). For example, LTE-M technology may be implemented as at least one of various standards such as 1) LTE Cat 0, 2) LTE Cat M1, 3) LTE Cat M2, 4) LTE non-bandwidth limited (non-BL), 5) LTE-MTC, 6) LTE machine-type communication, and / or 7) LTE M, and is not limited to the aforementioned names. Alternatively or additionally, the wireless communication technology implemented in the wireless devices 100a to 100f of this disclosure may include at least one of Bluetooth, Low Power Wide Area Network (LPWAN), and ZigBee for low power communication, and is not limited to the names mentioned above. As an example, ZigBee technology may generate personal area networks (PANs) related to low / low power digital communication based on various standards including IEEE 802.15.4, and may be referred to by various names.

[0140] Wireless devices 100a to 100f can connect to network 300 via BS 200. AI technology can be applied to wireless devices 100a to 100f, and wireless devices 100a to 100f can connect to AI server 400 via network 300. Network 300 can be configured using a 3G network, a 4G (e.g., LTE) network, or a 5G (e.g., NR) network. Although wireless devices 100a to 100f can communicate with each other via BS 200 / network 300, wireless devices 100a to 100f can perform direct communication with each other (e.g., sidelink communication) without going through the BS / network. For example, vehicles 100b-1 and 100b-2 can perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). IoT devices (e.g., sensors) can perform direct communication with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.

[0141] Wireless communication / connections 150a, 150b, or 150c can be established between wireless devices 100a to 100f / BS 200 or BS200 / BS 200. Here, the wireless communication / connection can be established via various RATs (e.g., 5G NR) such as uplink / downlink communication 150a, sidelink communication 150b (or D2D communication), or inter-BS communication (e.g., relay, access backhaul integration (IAB)). The wireless devices and BS / wireless devices can transmit / receive radio signals to / from each other via wireless communication / connections 150a and 150b.

[0152] Can be via Figure 15 The signal processing circuit 1000 converts codewords into radio signals. In this document, a codeword is a sequence of encoded bits for an information block. The information block may include a transport block (e.g., a UL-SCH transport block, a DL-SCH transport block). Radio signals can be transmitted via various physical channels (e.g., PUSCH and PDSCH).

[0153] Specifically, the codeword can be converted into a scrambled bit sequence by scrambler 1010. The scrambling sequence used for scrambling can be generated based on an initial value, which may include the ID information of the wireless device. The scrambled bit sequence can be modulated into a modulation symbol sequence by modulator 1020. The modulation scheme may include pi / 2-binary phase shift keying (pi / 2-BPSK), m-phase shift keying (m-PSK), and m-quadrature amplitude modulation (m-QAM). The complex modulation symbol sequence can be mapped to one or more transmission layers by layer mapper 1030. The modulation symbol of each transmission layer can be mapped (pre-encoded) to one or more corresponding antenna ports by pre-encoder 1040. The output z of pre-encoder 1040 can be obtained by combining the output y of layer mapper 1030 with N The M precoding matrix W is obtained by multiplying the two matrices. Here, N is the number of antenna ports, and M is the number of transmission layers. The precoder 1040 can perform precoding after performing transform precoding (e.g., DFT) for complex modulation symbols. Alternatively, the precoder 1040 can perform precoding without performing transform precoding.

Time-frequency resources may include multiple symbols in the time domain (e.g., CP-OFDMA symbols and DFT-s-OFDMA symbols) and multiple subcarriers in the frequency domain. Signal generator 1060 can generate radio signals from the mapped modulation symbols, and the generated radio signals can be transmitted to other devices via each antenna. For this purpose, signal generator 1060 may include an inverse fast Fourier transform (IFFT) module, a cyclic prefix (CP) inserter, a digital-to-analog converter (DAC), and an up-converter.

[0155] Can be with Figure 15 The signal processing procedures (1010~1060) are configured in reverse order for the signal processing procedures used to receive signals in a wireless device. For example, a wireless device (e.g., Figure 14 The receiver (e.g., 100, 200) can receive radio signals from the outside via the antenna port / transceiver. The received radio signals can be converted into baseband signals using a signal recovery unit. For this purpose, the signal recovery unit may include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a Fast Fourier Transform (FFT) module. Next, the baseband signals can be recovered into codewords through a resource demapping process, a post-encoding process, a demodulation processor, and a descrambling process. The codewords can be recovered into the original information blocks through decoding. Therefore, the signal processing circuitry (not illustrated) used for receiving signals may include a signal recovery unit, a resource demapping unit, a post-encoder, a demodulator, a descrambler, and a decoder.
