[0030] Technical features described individually within one drawing in this disclosure may be implemented individually or simultaneously.

[0031] In the present disclosure, a higher layer parameter may be a parameter that is set for the terminal, pre-set, or pre-defined. For example, a base station or a network may transmit the higher layer parameter to the terminal. For example, the higher layer parameter may be transmitted via radio resource control (RRC) signaling or medium access control (MAC) signaling.

[0032] In the present disclosure, "configured or defined" may be interpreted as being configured or pre-configured to a device through pre-defined signaling (e.g., SIB, MAC, RRC) from a base station or network. In the present disclosure, "configured or defined" may be interpreted as being pre-configured to a device.

[0034] The technology proposed in this disclosure can be used in various wireless communication systems such as CDMA (code division multiple access), FDMA (frequency division multiple access), TDMA (time division multiple access), OFDMA (orthogonal frequency division multiple access), and SC-FDMA (single carrier frequency division multiple access). CDMA can be implemented with wireless technologies such as UTRA (universal terrestrial radio access) or CDMA2000.

[0035] The technology proposed in this disclosure can be implemented as 6G wireless technology and can be applied to various 6G systems. For example, 6G systems may have key factors such as eMBB (enhanced mobile broadband), URLLC (ultra-reliable low latency communications), mMTC (massive machine-type communication), AI (artificial intelligence) integrated communication, tactile internet, high throughput, high network capacity, high energy efficiency, low backhaul and access network congestion, and enhanced data security.

[0036] FIG. 1 illustrates a communication procedure between devices according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0037] Referring to FIG. 1, in step S101, the first device and the second device can perform synchronization. For example, the first device may be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device may be a base station, a network, a RAN node, an NTN node / cell, a TRP, a terminal and / or at least one of the devices proposed in the present disclosure. For example, the first device may perform an initial cell search operation. For example, the first device may detect at least one synchronization signal transmitted according to a rule predefined by the second device. Here, for example, the synchronization signal may include a plurality of synchronization signals (e.g., primary synchronization signal, secondary synchronization signal, etc.) classified according to structure or use. Through this, the first device can identify the boundaries of the frame, subframe, time unit, slot, and / or symbol of the second device, and the first device can obtain information about the second device (e.g., cell identifier).

[0038] In step S103, the first device may obtain system information transmitted by the second device. For example, the system information may include information related to the attributes, characteristics, and / or capabilities of the second device that are necessary to connect to the second device and use the service. For example, the system information may be classified according to content (e.g., whether it is essential for connection), transmission structure (e.g., the channel used, whether it is provided on-demand), etc. For example, the system information may be classified into a master information block (MIB) and a system information block (SIB). For example, if necessary, the first device may transmit a signal requesting the system information prior to receiving the system information. For example, the request and provision of the system information may be performed after a random access procedure described later.

[0039] In step S105, the first device and the second device may perform a random access procedure. For example, the first device may transmit and / or receive at least one message for the random access procedure (e.g., random access preamble, random access response message, etc.) based on information related to the random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device may transmit a preamble (e.g., Msg1) through the random access channel, and the first device may receive a random access response message (e.g., Msg2). The first device may transmit a message (e.g., Msg3) containing information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device may receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be transmitted and received as a single message (e.g., MsgA), and / or Msg2 and Msg4 can be transmitted and received as a single message (e.g., MsgB).

[0040] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer controlling the connection (e.g., a radio resource control (RRC) layer), a layer handling mapping between a logical channel and a transmission channel (e.g., a media access control (MAC) layer), and a layer handling a physical channel (e.g., a physical (PHY) layer). For example, the first device and the second device may perform at least one of signaling to establish a connection, signaling to determine settings related to communication, and / or signaling to indicate allocated resources. For example, the control information may be signaled / transmitted through a control channel. For example, the control information and / or the control channel may be used to schedule at least one of data, a data channel (e.g., a shared channel), and / or control information on the data channel.

[0041] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process data based on signaling of control information and transmit and / or receive it. For example, when transmitting data, the first device or the second device may perform at least one of channel encoding, rate matching, scrambling, constellation mapping, layer mapping, waveform modulation, antenna mapping, and / or resource mapping on the information bits. For example, when receiving data, the first device or the second device may perform at least one of signal extraction from resources, antenna-specific waveform demodulation, signal placement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0042] For example, the layers of the radio interface protocol between the first device and the second device can be classified into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, the physical layer belonging to layer 1 can provide an information transfer service using a physical channel, and the radio resource control (RRC) layer located at layer 3 can perform the role of controlling radio resources between the first device and the second device. To this end, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0043] FIG. 2 illustrates a radio protocol architecture according to one embodiment of the present disclosure. The embodiment of FIG. 2 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of said embodiment may be omitted. For example, FIG. 2(a) may represent a radio protocol stack in the user plane for uplink communication or downlink communication, and FIG. 2(b) may represent a radio protocol stack in the control plane for uplink communication or downlink communication. For example, FIG. 2(c) may represent a radio protocol stack in the user plane for device-to-device communication, and FIG. 2(d) may represent a radio protocol stack in the control plane for device-to-device communication.

[0044] For example, the physical layer can provide information transmission services to upper layers using a physical channel. For example, the physical layer can be connected to the upper layer, the MAC (medium access control) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through a transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted through a wireless interface. For example, data can be transmitted through a physical channel between different physical layers (e.g., between the physical layers of a first device and a second device). For example, the physical channel can be modulated using the OFDM (orthogonal frequency division multiplexing) method, and time and frequency can be utilized as wireless resources.

[0045] For example, the MAC layer can provide services to the upper layer, the RLC (radio link control) layer, through logical channels. For example, the MAC layer can provide mapping functions from multiple logical channels to multiple transmission channels. For example, the MAC layer can provide logical channel multiplexing functions through mapping from multiple logical channels to a single transmission channel. For example, the MAC sublayer can provide data transmission services over logical channels.

[0046] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee various quality of service (QoS) required by a radio bearer (RB), the RLC layer can provide three modes of operation: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat requests (ARQ).

[0047] For example, the RRC (radio resource control) layer may be defined only in the control plane. For example, the RRC layer may be responsible for controlling logical channels, transmission channels, and physical channels in relation to the configuration, reconfiguration, and release of radio bearers. For example, RB may refer to a logical path provided by the first layer (e.g., physical layer) and the second layer (e.g., MAC layer, RLC layer, PDCP (packet data convergence protocol) layer, SDAP (service data adaptation protocol) layer, etc.) for data transfer between a first device and a second device.

[0048] For example, the functions of the PDCP layer in the user plane may include the delivery of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include the delivery of control plane data and encryption / integrity protection.

[0049] For example, the establishment of an RB can mean the process of defining the characteristics of the wireless protocol layer and channel to provide specific services, and setting each specific parameter and method of operation. For example, an RB can be divided into two types: an SRB (signaling radio bearer) and a DRB (data radio bearer). For example, an SRB can be used as a channel to transmit RRC messages in the control plane, and a DRB can be used as a channel to transmit user data in the user plane.

[0050] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) that transmits system information and / or a shared channel (SCH) that transmits user traffic or control messages. For example, traffic or control messages for a downlink multicast or broadcast service may be transmitted via a downlink SCH or via a separate multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) that transmits initial control messages and / or a shared channel (SCH) that transmits user traffic or control messages. For example, a logical channel located above the transmission channel and mapped to the transmission channel may include at least one of a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and / or a multicast traffic channel (MTCH).

[0051] FIG. 3 illustrates a communication structure that can be provided in a 6G system according to one embodiment of the present disclosure. The embodiment of FIG. 3 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0052] As core implementation technologies for 6G systems, technologies such as artificial intelligence (AI), THz (Terahertz) communication, optical wireless technology, free space optical transmission (FSO) backhaul networks, massive MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0053] - Artificial Intelligence: Introducing AI into communications can streamline and enhance real-time data transmission. AI can determine how complex target tasks are performed using numerous analyses. For example, AI can increase efficiency and reduce processing latency. Time-consuming tasks such as handover, network selection, and resource scheduling can be performed instantly using AI. AI can also play a significant role in M2M, machine-to-human, and human-to-machine communication. Furthermore, AI can enable rapid communication in Brain-Computer Interfaces (BCI). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0054] - THz Communication: Data transmission rates can be increased by expanding bandwidth. This can be achieved by using sub-THz communication with wide bandwidth and applying advanced large-scale MIMO technology. THz waves, also known as sub-millimeter radiation, generally refer to a frequency band between 0.1 THz and 10 THz with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz-300 GHz band range (Sub-THz band) is considered the primary portion of the THz band for cellular communication. Adding the Sub-THz band to the mmWave band increases 6G cellular communication capacity. Among the defined THz bands, the 300 GHz-3 THz band is located in the far-infrared (IR) frequency band. Although the 300 GHz-3 THz band is part of the optical band, it lies at the boundary of the optical band and immediately following the RF band. Therefore, this 300 GHz-3 THz band exhibits similarities to RF. Key characteristics of THz communication include (i) widely available bandwidth to support very high data transmission rates, and (ii) high path loss occurring at high frequencies (highly directional antennas are indispensable). The narrow beam width generated by highly directional antennas reduces interference. The small wavelength of THz signals allows a much larger number of antenna elements to be integrated into devices and BSs operating in this band. This enables the use of advanced adaptive array technologies that can overcome range limitations.

[0068] - Advanced Air Mobility (AAM): AAM can be a broad concept encompassing Urban Air Mobility (UAM), Regional Air Mobility (RAM), and Uncrewed Aerial Systems (UAS). For example, AAM may include UAM, RAM, UAS, and UAVs (uncrewed aerial vehicles).

[0069] - Autonomous driving (self-driving): V2X (vehicle to everything), a core element of building autonomous driving infrastructure, refers to technologies that enable vehicles to communicate and share with various elements on the road to perform autonomous driving, such as wireless communication between vehicles (vehicle to vehicle, V2V) and between vehicles and infrastructure (vehicle to infrastructure, V2I).

[0070] - Non-terrestrial Network (NTN): An NTN may refer to a network or network segment that utilizes RF (radio frequency) resources mounted on a satellite (or UAS platform). The use of NTN services may be considered to secure wider coverage or to provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0071] - Integrated Sensing and Communication (ISAC)

[0072] - Reconfigurable Intelligent Surface (RIS): An RIS can be used to manipulate and enhance signal propagation in a wireless communication environment. For example, an RIS can be composed of many small antennas or metasurfaces arranged on a surface, each of which can actively control the phase, amplitude, polarization, etc., of the reflected signal. For instance, an RIS can improve signal reception by controlling the path, phase, and / or strength of the propagating signal. For instance, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For instance, since an RIS can be reconfigured to suit various environments, it can meet diverse communication requirements and operate effectively in dynamic network environments.

[0073] Meanwhile, as the performance of Electronic Control Units (ECUs) improves in the automotive industry, there is a shift from combinations of distributed individual ECUs to integrated, high-performance central ECUs. Simultaneously, there is active interest and development in Software Defined Vehicles (SDVs), which define and control vehicle functions through software. While conventional vehicles were designed around hardware, SDVs integrate internal and external systems into software, enabling flexible control of various functions such as autonomous driving, infotainment, and driver assistance systems. Similar to the smartphone revolution, this offers the advantage of continuously improving functionality through software updates and is expected to play a crucial role in future mobility, particularly in autonomous vehicles. In other words, SDVs will make it easier to provide consumers with continuous performance improvements and new features through software updates and upgrades, without altering the vehicle's mechanical components (e.g., chassis, drivetrain, braking system, steering system, exterior, etc.). For example, it can enable features that provide continuously enhanced safety, convenience, and mobility to vehicle users (e.g., drivers, passengers) at a low cost. Additionally, for instance, by continuously monitoring, updating, or upgrading the software of ECUs used for engine control, it is possible to improve vehicle fuel efficiency and reduce emissions to meet environmental regulations. Furthermore, for instance, driving performance and the safety of drivers and passengers can be enhanced through software updates or upgrades of Advanced Driving Assistance Systems (ADAS) and Automated Driving Systems (ADS).

[0074] For example, as SDVs become more widespread, new features or improvements to existing ones may be possible through software updates or upgrades without replacing mechanical parts; however, the capabilities of electric and electronic components (e.g., computation, memory, power, etc.) required by the updated or upgraded software may increase. For instance, technological advancements will increase the computing power required by the functions and software of new vehicles, and to power this, new vehicles will require onboard units and peripherals (e.g., ECUs, memory, batteries, etc.) with increased computing power. However, the computing resources and capabilities of onboard units installed in existing SDVs are limited, and installing high-performance onboard units from the outset to anticipate high future requirements may lead to cost issues. To address this, offboard computation or offloading can be utilized. For example, when a specific function / software of a vehicle is offloaded and computed offboard (e.g., server, cloud), the vehicle transmits unprocessed information / data (e.g., sensor data) of the vehicle to the offboard (e.g., server, cloud, third system) and receives the information processed offboard to use the offloaded function.

[0075] Meanwhile, off-board computing or offloading can overcome the limitations of a vehicle's onboard system by enabling continuously evolving high-performance functions / software or complex data processing; however, since the vehicle must exchange data to offload functions / software, it is inevitably dependent on network performance (e.g., latency, packet loss / errors, throughput, etc.). Furthermore, not only the network performance between the vehicle and the off-board system but also the computing performance of the off-board system can affect the overall quality of service for offloading. For instance, if the Quality of Service (QoS) of offloading—including off-board computing performance or communication / network performance—is poor, functions / software may not be able to execute stably and smoothly. For example, in autonomous driving systems directly linked to vehicle safety, latency and reliability are critical factors. For example, when a vehicle's autonomous driving functions are offloaded, data transmission and processing take time, which can cause delays in situations requiring real-time operation. Furthermore, immediate responses are required in scenarios such as emergency braking or collision avoidance, and offloaded computation may struggle to meet these demands if the quality of the offloading service is degraded. Additionally, if a vehicle is located in the outskirts of an urban area or in a region with weak network coverage, data transmission may be unreliable or impossible. This can disrupt the vehicle's autonomous driving functions or real-time data processing, posing a significant safety risk.

[0076] The present disclosure proposes a method and apparatus that support the same, wherein when a vehicle performs offboard computing or offloading one or more functions or software of the vehicle, the priority of the functions or software to be offloaded is set and the offloading is coordinated based on the predicted Quality of Service (QoS) of the offloading.

[0077] For example, when it is decided or proceeded to perform computations for high-performance vehicle functions / software—such as data analysis, remote or autonomous driving, or user convenience features—offboard rather than onboard, the vehicle's onboard system uploads information / data for computation to the offboard system (e.g., cloud, server, third-party system). Upon receiving this, the offboard system performs a specific function (e.g., data processing) and then transmits the computation result data back to the vehicle's onboard system. For instance, the vehicle's onboard system can receive values ​​computed offboard and execute the corresponding function / software. Here, "vehicle" may refer to the vehicle's onboard system and local devices, while "offboard" may refer to external systems other than local devices. Additionally, for instance, "offboard computation" or "offloading" may refer to data processing taking place on an offboard system (e.g., server, cloud, surrounding vehicle) that is an external device / system to the device where the data was generated (e.g., vehicle, sensor, EUC, onboard). Alternatively, for example, it may mean executing vehicle functions / software by utilizing off-board computing resources rather than on-board computing resources. In this case, for example, computing resources may include all components and information necessary to execute vehicle functions / software, such as computing units (e.g., CPU, GPU, etc.), storage devices (e.g., RAM, SSD, HDD, etc.), power sources (e.g., battery, power supply unit, etc.), platforms (e.g., digital twin, simulation tool, etc.), information / data (e.g., traffic information, statistics-based database, etc.), and machine learning / artificial intelligence models. Furthermore, for example, functions / software may include applications, containers, code, libraries, environment variables and configuration files, data computation, and data storage executed to perform said functions / software.

[0078] In this disclosure, a method for setting the offloading priority of a vehicle's functions / software using one or more of the values ​​listed below is proposed.

[0079] (1) Function type: Type of function / software to be offloaded

[0080] For example, it can be configured based on driving functions, safety functions, comfort / convenience functions, or infotainment.

[0081] (2) Safety Integrity Level (SIL) (or (Automotive) SIL): A level derived through threat and hazard analysis and risk assessment of the function / software to be offloaded (e.g., HARA (Hazard Analysis and Risk Assessment), TARA (Threat Analysis and Risk Assessment)).

[0082] For example, it can be set to QM (Quality Management), (A)SIL A, (A)SIL B, (A)SIL C, or (A)SIL D.

[0083] Alternatively, it may be defined based on functional and safety standards, such as IEC 61508, IEC 62601, ISO 26262, or cybersecurity standards, such as ISO / SAE 21434.

[0084] (3) Consecutiveness: The level and / or time (value) at which off-board operations related to the function / software to be offloaded must be continuous or sustained

[0085] For example, the continuity level can be set to High, Mid, or Low.

[0086] Alternatively, for example, a time value requiring continuity (e.g., target maintain time) can be set.

[0087] (4) Requirements: Function / software requirements

[0088] For example, it can be configured based on the following items required by the function / software to be offloaded.

[0089] - Transmission rate: The data transmission speed required by the function / software

[0090] - Latency: The latency required by the function / software

[0091] - Packet Loss Rate / Packet Error Rate: The packet loss / error rate required by the function / software

[0092] - Throughput: The amount of processing required by a function / software

[0093] - Jitter: Jitter required by the function / software

[0094] - Scalability: Variability of function / software requirements and ability to respond to predicted QoS

[0095] For example, the vehicle can use the information listed above to set the offloading priority of each function / software. For instance, the priority factors listed above (e.g., factors for setting offloading priorities) can be utilized as input parameters for priority setting functions, machine learning / artificial intelligence (e.g., reinforcement learning), or dynamic scheduling (e.g., ACO (Ant Colony Optimization)).

[0096] In addition, the present disclosure proposes a method for transmitting the priority setting (e.g., offloading priority) after setting the priority elements (e.g., elements for setting offloading priority) and / or the priority based thereon. For example, priority information of a function / software defined by the offboard (e.g., elements for setting offloading priority or offloading priority setting) may be transmitted to the onboard. Alternatively, for example, priority information of a function / software defined by the onboard (e.g., elements for setting offloading priority or offloading priority setting) may be transmitted to the offboard. In this case, for example, a protocol and / or interface between the vehicle's onboard and offboard may be required to transmit the set priority.

[0097] Table 2 below shows the priority elements of the function / software to be offloaded that may be included in messages transmitted and received between onboard and offboard to set the offloading priority.

[0098] For example, the vehicle can transmit priority information to the offboard as shown in Table 2 below to allow the offboard to set the offloading priority of the function / software.

[0099] Function Type: Driving function, safety function, convenience function, or infotainment Safety Integrity Level (SIL) QM, (A) SIL A, (A) SIL B, (A) SIL C, or (A) SIL D Continuity: High, Medium, Low Target Maintenance Time Requirements Transmission Rate Latency Packet Loss Rate, Packet Error Rate Throughput Jitter Scalability

[0100] Furthermore, the present disclosure proposes a method for coordinating offloading based on priority setting values ​​of functions / software and predictive QoS of offloading. For example, the vehicle or offboard may compute and share predictive offloading QoS information to measure and predict the quality of service of the onboard transmission of unprocessed data, offboard computation, and processing data reception processes, which are part of the vehicle's offloading process, in order to predict potential performance degradation during future offloading operations and to prepare for the smooth operation of the vehicle's functions. In this case, for example, offloading QoS (or predictive offloading QoS information) may refer to communication / network performance connecting the vehicle's onboard and offboard, offboard computational performance, offboard availability, etc. For example, offloading service quality (or offloading QoS) can be measured and / or predicted based on statistical modeling, simulation, real-time data, or machine learning / artificial intelligence.

[0101] FIG. 4 illustrates a method for adjusting offloading priorities offboard according to one embodiment of the present disclosure. The embodiment of FIG. 4 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0102] For example, upon receiving priority factors and / or priority values ​​defined based on the offloading's predicted QoS, the offboard can adjust the allocation of computing resources for each function / software according to priority. For instance, if the predicted QoS fluctuates, the offboard can use the priority received from the onboard in a priority queue to allow the onboard to offload high-priority functions / software first.

[0103] Specifically, referring to FIG. 4, if the vehicle's onboard determines that it is impossible to execute a specific function / software using only onboard computing resources, the vehicle's onboard may send an offboard request to request an operation (e.g., offboard operation) related to the specific function / software to the offboard. For example, upon receiving an offboard request from the onboard, the offboard may allocate its computing resources for the onboard. For example, when the allocation of computing resources for the onboard is completed at the offboard, the offboard may send an offboard approval to the onboard. For example, the vehicle's onboard may initiate an offboard procedure based on receiving the offboard approval. For example, if the vehicle's onboard measures and acquires data (e.g., unprocessed data) based on one or more sensors mounted on the vehicle, the vehicle's onboard may transmit the data to the offboard. For example, the vehicle's onboard may transmit unprocessed data to the offboard for offboarding. For example, the off-board, having received unprocessed data from the on-board, can perform off-board operations based on computing resources allocated for the on-board. For example, if the off-board obtains processed data based on off-board operations on the unprocessed data, the off-board can transmit the processed data to the on-board.

[0104] For example, through the offloading procedure described above, the vehicle's onboard can measure / predict the offloading QoS. For example, if the vehicle's onboard sets offloading priorities for one or more functions / software in accordance with the proposal of the present disclosure, the vehicle's onboard can transmit the offloading priority settings and the measured / predicted offloading QoS to the offboard. Or, for example, the vehicle's onboard can transmit information used for setting offloading priorities (e.g., offloading priority determining factors) to the offboard. For example, the offboard can adjust (or reset) the offloading settings based on the offloading priority settings (or information used for setting offloading priority) received from the onboard. Or, for example, the offboard can adjust (or reset) the offloading settings based on the offloading priority settings (or information used for setting offloading priority) and the offloading QoS received from the onboard. Alternatively, for example, if the offboard receives only offloading priority settings from the onboard and not offloading QoS, the offboard may measure / predict the offloading QoS and adjust (or reset) the offloading settings based on the measured / predicted offloading QoS and the received offloading priority settings (or information used for offloading priority settings). Meanwhile, for example, the offboard may transmit offloading (re)setting information (or adjusted offloading setting information) to the onboard, and the vehicle's onboard may perform offloading based on the offloading (re)setting information (or adjusted offloading setting information) received from the offboard. In this case, for example, the vehicle's onboard may offload some of one or more functions based on the offloading (re)setting information (or adjusted offloading setting information), and perform the remaining functions based on onboard operations without offloading.

[0105] FIG. 5 illustrates a method for adjusting offloading priorities onboard according to one embodiment of the present disclosure. The embodiment of FIG. 5 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0106] For example, a vehicle that receives priority elements and / or priority values ​​defined based on the predicted QoS of offloading can request offloading after adjusting the offloading request to the priority for each function / software.

[0107] Specifically, referring to FIG. 5, if the vehicle's onboard determines that it is impossible to execute a specific function / software using only onboard computing resources, the vehicle's onboard may send an offboard request to request an operation (e.g., offboard operation) related to the specific function / software to the offboard. For example, upon receiving an offboard request from the onboard, the offboard may allocate its computing resources for the onboard. For example, when the allocation of computing resources for the onboard from the offboard is completed, the offboard may send an offboard approval to the onboard. For example, the vehicle's onboard may initiate an offboard procedure based on receiving the offboard approval. For example, if the vehicle's onboard measures and acquires data (e.g., unprocessed data) based on one or more sensors mounted on the vehicle, the vehicle's onboard may transmit the data to the offboard. For example, the vehicle's onboard may transmit unprocessed data to the offboard for offboarding. For example, the off-board, having received unprocessed data from the on-board, can perform off-board operations based on computing resources allocated for the on-board. For example, if the off-board obtains processed data based on off-board operations on the unprocessed data, the off-board can transmit the processed data to the on-board.

[0108] For example, through the off-boarding procedure described above, the off-board can measure / predict the off-boarding QoS. For example, the off-board can transmit the off-boarding settings and the measured / predicted off-boarding QoS to the vehicle's on-board. Alternatively, for example, the off-board can transmit information used for setting off-boarding priorities (e.g., off-boarding priority determining factors) to the vehicle's on-board. For example, the vehicle's on-board can adjust (or reset) the off-boarding settings based on the off-boarding QoS received from the off-board. Alternatively, for example, if the vehicle's on-board receives only the off-boarding settings and not the off-boarding QoS from the off-board, the vehicle's on-board can measure / predict the off-boarding QoS and adjust (or reset) the off-boarding settings based on the measured / predicted off-boarding QoS and off-boarding priorities. For example, the vehicle's on-board can perform off-boarding based on the adjusted (or reset) off-boarding settings. For example, an adjusted (or reset) offloading setting may include an adjusted offloading priority for one or more functions that are the subject of offloading. In this case, for example, the vehicle's onboard may offload some of the one or more functions based on the adjusted (or reset) offloading setting, and perform the remaining functions based on onboard operations without offloading.

[0109] FIG. 6 illustrates a method for setting offloading priorities according to one embodiment of the present disclosure. The embodiment of FIG. 6 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0110] Referring to FIG. 6, the vehicle may use various functions / software based on off-board computation. For example, when the vehicle is driving using one or more functions via off-board computation, the off-board priority of the functions / software to be off-boarded can be set. For example, as proposed in the present disclosure, the priority can be set based on the Automotive Safety Integrity Level (ASIL). For example, the vehicle's onboard can offload Function A (e.g., autonomous driving), Function B (e.g., vision sensor data processing), and Function C (e.g., infotainment). In this case, for example, if the off-board priority is set based on ASIL, Function A can be set to a high priority of 'ASIL D', Function B can be set to a medium priority of 'ASIL C', and Function C can be set to a low priority of 'ASIL A'. For example, when the vehicle sets the off-board priority for one or more functions, the vehicle can transmit the off-board priority setting. Meanwhile, for example, the vehicle may receive information predicting the off-board off-loading QoS. For instance, Functions A, B, and C may all be off-loaded in sections of the planned route that have a high off-loading QoS, but the off-loading may be adjusted based on the prediction that the QoS will degrade in urban areas. In this case, for instance, the off-loading may be adjusted so that only the high-priority Functions A and B are off-loaded (e.g., when the vehicle requests off-board off-loading, it requests off-loading only for Functions A and B, excluding Function C). Alternatively, for instance, based on the adjusted off-board priority, high-priority functions (e.g., Functions A and B) may be performed on-board, while only low-priority functions (e.g., Function C) may be performed off-board.Alternatively, for example, when low offloading QoS is predicted due to communication / network performance degradation, Function A, which has high functional safety requirements, can be excluded from offloading by performing it onboard, while Functions B and C, which are insensitive to offloading QoS, can be performed as offboard operations.

[0111] Meanwhile, the proposal of the present disclosure may be applied not only when the vehicle adjusts / resets offloading settings based on offloading QoS obtained from the offboard as in the embodiment of FIG. 6 described above, but also when the offboard adjusts / resets offloading settings based on offloading QoS and transmits them to the vehicle. For example, when the offboard (or server) adjusts offloading settings based on offloading priorities received from the onboard, it may instruct the vehicle to offload only high-priority functions. Alternatively, for example, when the offboard (or server) adjusts offloading settings based on offloading priorities received from the onboard, it may instruct the vehicle to perform high-priority functions on the onboard and offload only low-priority functions.

[0112] FIG. 7 illustrates a flowchart of an operation for setting and / or adjusting an offloading priority according to one embodiment of the present disclosure. The embodiment of FIG. 7 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0113] Referring to FIG. 7, in step S710, the vehicle's onboard can analyze the offloading priority elements of the function / software to be offloaded and set the offloading priority based thereon. In step S720, the onboard can transmit the offloading priority elements of the function / software and / or the offloading priority setting to the offboard. Alternatively, for example, if the onboard obtains offloading prediction QoS information by measuring and predicting the offloading service quality, it can transmit such information to the offboard. For example, as described above, offloading prediction QoS information can be obtained from the onboard and transmitted to the offboard, or the offboard can directly measure and predict the offloading service quality to obtain offloading prediction QoS information. In step S730, the offboard can adjust the offloading based on the offloading priority setting of the function / software received from the onboard. Alternatively, for example, if the offboard obtains offloading prediction QoS information, the offboard may adjust the offloading by considering the offloading priority setting and the offloading prediction QoS information together. In step S740, the offboard may request the onboard to perform the adjusted offloading. Specifically, for example, the offboard may transmit offloading settings to the onboard, and the offloading settings transmitted by the offboard to the onboard may include the offloading priority setting adjusted by the offboard in the aforementioned step S730. For example, the offboard may request the onboard to perform offloading based on the adjusted offloading priority setting included in the offloading settings.

[0114] FIG. 8 illustrates a method in which a first device performs wireless communication according to one embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0115] Referring to FIG. 8, at step S810, an offloading priority associated with a first offloading setting can be set. At step S820, information associated with the offloading priority can be transmitted to a second device. At step S830, a second offloading setting adjusted based on the offloading priority can be received from the second device.

[0116] For example, the second offloading setting may include information requesting the second device to perform offloading adjusted based on the second offloading setting.

[0117] For example, the above offloading priority may be set based on information related to at least one of (i) the type of function to be offloaded, (ii) the safety integrity level of the function to be offloaded, (iii) the continuity level of the function to be offloaded, or (iv) the requirements of the function to be offloaded.

[0118] For example, based on the second offloading setting above, the allocation of computing resources for offloading the first device can be adjusted.

[0119] Additionally, for example, the first device may adjust the offloading priority of one or more functions subject to offloading based on the second offloading setting. For example, at least one of the one or more functions included in the offloading priority associated with the first offloading setting may be excluded from the target of offloading based on the second offloading setting. For example, at least one of the one or more functions may be performed based on the onboard operation of the first device.

[0120] For example, the second offloading setting may be obtained by adjusting the first offloading setting based on (i) the offloading priority and (ii) the predicted Quality of Service (QoS) associated with offloading. For example, the predicted QoS obtained based on the transmission of unprocessed data from the first device to the second device and the reception of processed data from the second device to the first device may be transmitted from the first device to the second device. For example, the predicted QoS obtained based on information related to the planned path of the first device or information related to the expected path of the first device may be transmitted from the first device to the second device. For example, the predicted QoS may be obtained based on at least one of statistical modeling, simulation, real-time data, machine learning, or artificial intelligence. For example, the lower the predicted QoS, the greater the degree of adjustment for the first offloading setting may be.

[0121] Additionally, for example, the first device may transmit at least one priority determination element related to the offloading priority to the second device.

[0122] The proposed method above may be applied to a device according to various embodiments of the present disclosure. First, a processor (102) of a first device (100) may set an offloading priority associated with a first offloading setting. Then, the processor (102) of the first device (100) may control a transceiver (106) to transmit information associated with the offloading priority to a second device. Then, the processor (102) of the first device (100) may control a transceiver (106) to receive a second offloading setting adjusted based on the offloading priority from the second device.

[0123] According to one embodiment of the present disclosure, a first device configured to perform wireless communication may be provided. For example, the first device may include at least one transceiver; at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on the instructions executed by the at least one processor, the first device may: set an offloading priority associated with a first offloading setting; transmit information associated with the offloading priority to a second device; and receive a second offloading setting adjusted based on the offloading priority from the second device.

[0124] According to one embodiment of the present disclosure, a processing device configured to control a first device may be provided. For example, the processing device may include at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on the instructions executed by the at least one processor, the first device may: set an offloading priority associated with a first offloading setting; transmit information associated with the offloading priority to a second device; and receive a second offloading setting adjusted based on the offloading priority from the second device.

[0125] According to one embodiment of the present disclosure, a non-transient computer-readable storage medium recording instructions may be provided. For example, when the instructions are executed, the first device may: set an offloading priority associated with a first offloading setting; transmit information associated with said offloading priority to a second device; and receive a second offloading setting adjusted based on said offloading priority from the second device.

[0126] FIG. 9 illustrates a method in which a second device performs wireless communication according to one embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0127] Referring to FIG. 9, at step S910, information including an offloading priority associated with a first offloading setting can be received from the first device. At step S920, based on the information including the offloading priority, a second offloading setting adjusted from the first offloading setting can be obtained. At step S930, the second offloading setting can be transmitted to the first device.

[0128] The proposed method above may be applied to a device according to various embodiments of the present disclosure. First, a processor (202) of a second device (200) may control a transceiver (206) to receive information including an offloading priority related to a first offloading setting from a first device. Then, the processor (202) of the second device (200) may obtain a second offloading setting adjusted from the first offloading setting based on the information including the offloading priority. Then, the processor (202) of the second device (200) may control a transceiver (206) to transmit the second offloading setting to the first device.

[0129] According to one embodiment of the present disclosure, a second device configured to perform wireless communication may be provided. For example, the second device may include at least one transceiver; at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on the instructions being executed by the at least one processor, the second device may: receive information from the first device including an offloading priority associated with a first offloading setting; obtain a second offloading setting adjusted from the first offloading setting based on the information including the offloading priority; and transmit the second offloading setting to the first device.

[0130] According to one embodiment of the present disclosure, a processing device configured to control a second device may be provided. For example, the processing device may include at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on the instructions being executed by the at least one processor, the second device may: receive information from a first device including an offloading priority associated with a first offloading setting; obtain a second offloading setting adjusted from the first offloading setting based on the information including the offloading priority; and transmit the second offloading setting to the first device.

[0131] According to one embodiment of the present disclosure, a non-transient computer-readable storage medium recording instructions may be provided. For example, when the instructions are executed, the second device may: receive from the first device information including an offloading priority associated with a first offloading setting; obtain a second offloading setting adjusted from the first offloading setting based on the information including the offloading priority; and transmit the second offloading setting to the first device.

[0132] According to various embodiments of the present disclosure, by setting the priority of functions / software to be offloaded and adjusting them agilely according to the predicted offloading QoS, functions / software with high priority can be offloaded preferentially over other functions / software, thereby enabling the smooth operation of vehicle functions / software by preparing in advance even in situations where a decrease in QoS is predicted.

[0133] Alternatively, for example, onboard and / or offloading can maintain the level of performance required by the vehicle by adjusting offloading with priority values ​​set based on predictive QoS, thereby preparing for and preventing delays and interruptions in safety and performance-sensitive functions / software. For example, if the priority of functions / software is not set and latency increases or data transmission packets are lost due to degraded offloading QoS, the quality of the offloaded functions / software may not be guaranteed. However, according to various embodiments of the present disclosure, such cases can be prepared for and prevented in advance, and high-performance functions / software can be used in the vehicle through safe and robust offloading based on predictive QoS. In particular, this may be essential, for example, for driving and safety-related functions.

[0143] FIG. 11 shows a wireless device according to one embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0144] Referring to FIG. 11, the first wireless device (100) and the second wireless device (200) can transmit and receive wireless signals through various wireless access technologies (e.g., LTE, NR). Here, {the first wireless device (100), the second wireless device (200)} may correspond to {wireless device (100x), base station (200)} and / or {wireless device (100x), wireless device (100x)} of FIG. 10.

[0151] FIG. 12 shows a signal processing circuit for a transmission signal according to one embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0152] Referring to FIG. 12, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operation / function of FIG. 12 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 11. The hardware elements of FIG. 12 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 11. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 11. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 11, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 11.

[0153] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 12. Here, the codeword is an encoded bit sequence of an information block. The information block may include a transmission block (e.g., UL-SCH transmission block, DL-SCH transmission block). The wireless signal can be transmitted through various physical channels (e.g., PUSCH, PDSCH).

[0154] Specifically, a codeword can be converted into a scrambled bit sequence by a scrambler (1010). The scrambled sequence used for scrambling is generated based on an initialization value, which may include ID information of a wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by an N*M precoding matrix W. Here, N is the number of antenna ports and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on the complex modulation symbols. Additionally, the precoder (1040) can perform precoding without performing transform precoding.

[0155] A resource mapper (1050) can map the modulation symbols of each antenna port to a time-frequency resource. The time-frequency resource may include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. A signal generator (1060) generates a radio signal from the mapped modulation symbols, and the generated radio signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) may include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0156] The signal processing process for a received signal in a wireless device can be configured as the inverse of the signal processing process (1010–1060) of FIG. 12. For example, a wireless device (e.g., 100, 200 in FIG. 11) can receive a wireless signal from the outside through an antenna port / transceiver. The received wireless signal can be converted into a baseband signal through a signal restorer. To this end, the signal restorer may include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a Fast Fourier Transform (FFT) module. Subsequently, the baseband signal can be restored into a codeword through a resource de-mapper process, a postcoding process, a demodulation process, and a de-scrambling process. The codeword can be restored into the original information block through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
