[0040] 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.

[0041] 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).

[0042] 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.

[0043] 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).

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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).

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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).

[0055] FIG. 3 shows the structure of a wireless frame 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.

[0056] Referring to FIG. 3, radio frames may be used, for example, in uplink transmission, downlink transmission, and / or device-to-device transmission. For example, a radio frame may have a length of 10 ms and may be defined as two 5 ms half-frames (HF). For example, a half-frame may contain five 1 ms subframes (SF). For example, a subframe may be divided into one or more slots, and the number of slots within a subframe may be determined by subcarrier spacing (SCS). For example, each slot may contain 12 or 14 OFDM(A) symbols according to a cyclic prefix (CP).

[0057] For example, when normal CP is used, each slot may contain 14 symbols. For example, when extended CP is used, each slot may contain 12 symbols. Here, for example, the symbols may include OFDM symbols (or CP-OFDM symbols) and SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0058] Table 2 below shows the number of symbols per slot (N) according to the SCS setting (u) when Normal CP or Extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot) exemplifies.

[0059] CP Type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slot Normal CP 15kHz (u=0) 1410 130kHz (u=1) 1420 260kHz (u=2) 1440 4120kHz (u=3) 1480 8240kHz (u=4) 14160 16 Extended CP 60kHz (u=2) 1240 4

[0060] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be configured differently among multiple cells merged into a single terminal. Accordingly, the (absolute time) interval of a time resource (e.g., subframe, slot, or TTI (transmit time interval)) composed of the same number of symbols may be configured differently among the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTI, etc. may be referred to as time units.

[0061] For example, multiple numerologies or SCSs may be supported to support various services. For example, if the SCS is 15 kHz, a wide area in traditional cellular bands may be supported, and if the SCS is 30 kHz / 60 kHz, dense-urban, lower latency, and wider carrier bandwidth may be supported. For example, if the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz may be supported to overcome phase noise.

[0062] FIG. 4 shows a slot structure of a frame 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 the embodiments may be omitted.

[0063] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain and may correspond to a single numerology (e.g., SCS, CP length, etc.). For example, a carrier may include up to N BWPs (where N is a positive integer). For example, data communication may be performed through an active BWP. For example, each element may be referred to as a resource element (RE) in a resource grid and may be mapped to a single complex symbol.

[0064] For example, a BWP can be a continuous set of PRBs in a given numerology. For example, a PRB can be selected from a continuous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0065] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the terminal may not monitor downlink radio link quality on DL BWPs other than the active DL BWP on the PCell (primary cell). For example, the terminal may not receive PDCCH (physical downlink control channel), PDSCH (physical downlink shared channel), or CSI-RS (channel state information-reference signal) (except for RRM (radio resource management)) outside of the active DL BWP. For example, the terminal may not trigger CSI (channel state information) reporting for an inactive DL BWP. For example, the terminal may not transmit PUCCH (physical uplink control channel) or PUSCH (physical uplink shared channel) outside of the active UL (uplink) BWP. For example, for the downlink, the initial BWP can be given as a consecutive set of resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For example, for the uplink, the initial BWP can be given by the system information block (SIB) for the random access procedure. For example, the default BWP can be set by the upper layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if the terminal fails to detect DCI (downlink control information) for a certain period, the terminal can switch the active BWP of the terminal to the default BWP.

[0066] FIG. 5 illustrates an example of a BWP according to an 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, proposals, methods, and / or operations of the embodiments may be omitted. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0067] Referring to FIG. 5, for example, a common resource block (CRB) may be a numbered carrier resource block from one end of the carrier band to the other, and a PRB may be a numbered resource block within each BWP. For example, point A may indicate a common reference point for the resource block grid.

[0068] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP It can be set by ). For example, point A may be an external reference point of the PRB of a carrier where the subcarrier 0 of all numerologies (e.g., all numerologies supported by the network in that carrier) are aligned. For example, offset may be the PRB interval between the lowest subcarrier in a given numerology and point A. For example, bandwidth may be the number of PRBs in a given numerology.

[0069] FIG. 6 illustrates a communication structure that can be provided in a 6G system 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, proposals, methods, and / or operations of said embodiments may be omitted.

[0070] 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.

[0071] - 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.

[0072] - 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.

[0086] - 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).

[0087] - 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).

[0088] - 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.

[0089] - Integrated Sensing and Communication (ISAC)

[0090] - 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.

[0091] FIG. 7 illustrates an example of a communication scenario based on a 6G system according to an 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, proposals, methods, and / or operations of the embodiments may be omitted.

[0092] Referring to FIG. 7, NTN communication can be performed based on a satellite network, HIBS (high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS)), and an aeronautical communication-capable terminal (e.g., AAM). For example, to improve coverage, devices such as a satellite network, HIBS, and an aeronautical communication-capable terminal (e.g., AAM) can act as relays. For example, an AAM can communicate with a base station, a satellite network, etc., and / or an AAM can communicate directly with a terminal, another AAM, etc.

[0093] Below, the integrated sensing and communication (ISAC) mentioned above will be explained in detail.

[0094] Integrated Sensing and Communication (ISAC) refers to wireless sensing, a technology that utilizes radio frequencies to determine the instantaneous linear velocity, angle, and distance (range) of objects, thereby obtaining information about the characteristics of the environment and / or objects within that environment. Since radio frequency sensing capabilities do not require connecting to objects via devices within a network, they can provide services for object location determination without the need for devices. The ability to obtain range, velocity, and angle information from radio frequency signals can provide a wide range of new functions, such as various object detection and recognition (e.g., vehicles, humans, animals, UAVs), as well as high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to various industries (e.g., unmanned aerial vehicles, smart homes, V2X, factories, railways, public safety, etc.) that enable applications such as intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, and health and traffic management. In some cases, wireless sensing may utilize non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP-based sensing. For example, the operation of a wireless sensing service (e.g., sensing operation) may depend on the transmission, reflection, and scattering processing of wireless sensing signals. Thus, wireless sensing can provide an opportunity to enhance existing communication systems from communication networks to wireless communication and sensing networks. FIG. 8 illustrates an example of a sensing operation according to an 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, proposals, methods, and / or operations of said embodiment may be omitted. Specifically, FIG. 8(a) illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and FIG. 8(b) illustrates an example of sensing using a separated sensing receiver and a sensing transmitter (e.g., bistatic sensing).

For example, if BS#1 and BS#2 are the same BS, it may mean BS-BS mono-static sensing operation. For example, the BS may be a base station or a TRP (transmission and reception point). For example, if BS#1 and / or BS#2 are one or more BSs, it may mean BS-BS multi-static sensing operation.

[0108] - BS-UE sensing: Sensing in which a BS transmits a sensing RS and a UE receives the sensing RS. For example, the BS may be a base station or a TRP (transmission and reception point). For example, if the BS and / or the UE are one or more BSs and / or one or more UEs, it may imply a BS-UE multi-static sensing operation.

[0109] - UE-BS sensing: Sensing in which a UE transmits a sensing RS and a BS receives the sensing RS. For example, the BS may be a base station or a TRP (transmission and reception point).

For example, the BS may be a base station or a TRP (transmission and reception point). For example, if UE#1 and / or UE#2 are one or more UEs, this may mean a UE-UE multi-static sensing operation.

[0111] - Sensing Device: UE and / or TRP

[0112] - TSA: Target sensing area

[0113] - SMF: Sensing Management Function

[0114] - SF: Sensing function. In an ISAC, this may refer to a network entity that controls and manages the sensing procedures of a UE or TRP. For example, the SF can receive reports on sensing data collected by sensing a UE or TRP and can store such sensing data. Alternatively, for example, it can provide sensing data for a sensing service to a sensing device.

[0115] - Non-3GPP Sensing Data: Sensing data collected by performing sensing based on non-3GPP communication, rather than sensing data collected by performing sensing based on 3GPP communication (e.g., camera data, video data, or data collected by performing sensing based on other RATs (e.g., Wi-Fi)).

[0116] - Third party entity: This may refer to a server device operated by a sensing service operator (e.g., a business operator utilizing / operating sensing data for a sensing service). For example, it may receive and store sensing data for a sensing service from a sensing device. For example, it may provide sensing data for a sensing service to a sensing device.

[0117] - Forward Scatter: It is known that when the bistatic angle approaches 180 degrees, the RCS increases by more than tens of times—for example, by about 30 dB—compared to the monostatic case. This phenomenon can be explained using Babinet's principle. According to Babinet's principle, when a target-shaped hole is drilled in an infinite sheet of perfect conductors, the signal diffracted through that hole must have the same magnitude and opposite phase as the signal diffracting around a perfectly-absorbing target, and the sum of the two signals must be zero. In other words, the forward scatter effect is a result of co-phase disturbances of waves occurring in the target's shadow region. Due to this interference, the field is focused on a line perpendicular to the target's shadow region. In practice, the target's shadow beam exhibits high directional gain on the non-illuminated side of the target.

[0118] - Underlay Sensing Signal Transmission: Underlay sensing signal transmission refers to a communication concept that enables sensing devices participating in a sensing service to communicate simultaneously without affecting signals for existing communication services. It can be designed to avoid interfering with the communication service UE's communication by using low-power signals in the frequency band used by the communication service UE.

[0119] FIG. 9 illustrates a support scenario for a sensing service in an ISAC 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.

[0120] Referring to FIG. 9, the six main sensing modes are as follows. Specifically, FIG. 9 (a) represents gNB monostatic. In this case, the same gNB can perform both Tx and Rx roles. FIG. 9 (b) represents gNB bistatic. In this case, one gNB can perform the Tx role and the other gNB can perform the Rx role. FIG. 9 (c) represents gNB-to-UE bistatic. In this case, the gNB can perform the Tx role and the UE can perform the Rx role. FIG. 9 (d) represents UE-to-gNB bistatic. In this case, the UE can perform the Tx role and the gNB can perform the Rx role. FIG. 9 (e) represents UE monostatic. In this case, the same UE can perform both Tx and Rx roles. Figure 9 (f) represents a bi-static UE. In this case, one UE can perform the Tx role and another UE can perform the Rx role.

[0121] Meanwhile, in conventional communication (e.g., NR Uu or NR sidelink), the sensing procedure of a device (e.g., terminal or base station) was not considered a service. However, since the primary purpose of an ISAC service is to rapidly detect and distinguish a target object through sensing, it is necessary to classify the sensing procedure (or behavior) as a service that must satisfy a QoS requirement (e.g., sensing latency: the time taken from a terminal triggering the sensing procedure to receiving the sensing result of the target object from a receiving terminal, or sensing accuracy, etc.). For example, in ISAC, the sensing behavior of a device (e.g., terminal, base station, or SMF (sensing management function)) can be considered a service that must satisfy the ISAC sensing QoS requirement, and the terminal can perform a sensing behavior based on that sensing QoS (e.g., transmitting a sensing reference signal and / or receiving a sensing reference signal).

[0122] For example, sensing in ISAC can be considered as a higher-layer service that must satisfy sensing QoS (or sensing quality) based on sensing results, and a new QoS for ISAC sensing services (e.g., SQFI (Sensing QoS Flow ID)) can be defined as follows.

[0123] - SQFI(Sensing QoS Flow ID)

[0124] - SQFI 1 to 8: For example, they can be distinguished according to the level of sensing QoS requirements. For example, sensing QoS requirements may include sensing accuracy, sensing latency (e.g., the latency boundary from sensing triggering to receiving the sensing result), or sensing priority (e.g., a priority that can be used to determine which sensing service is opened first based on priority when multiple sensing procedures are required). For example, a smaller (or higher) SQFI value may be defined as a sensing service with tighter QoS requirements (e.g., a sensing service requiring high sensing accuracy, or a sensing service requiring low / lower / lowest sensing latency).

[0125] In addition, ISAC defines terminal and TRP (or base station) operations to support sensing services such as detection, localization, and tracking.

[0126] For example, the sensing QoS for ISAC services (detection, localization, tracking, etc.) may be as follows.

[0127] - Detection QoS: Detection probability, false alarm probability

[0128] - Localization QoS: Localization of the static objects, QoS parameter of localization (e.g., time delay, AoA (angle of arrival))

[0129] - Tracking QoS: Tracking changes in the state of a moving target (e.g., vehicle or drone) (range, angle, velocity, etc.)

[0130] FIG. 10 illustrates a QoS model for a conventional 5G communication service according to one embodiment of the present disclosure. The embodiment of FIG. 10 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.

[0131] Referring to FIG. 10, a QoS model (e.g., QoS flow to DRB mapping) is shown to support communication services (e.g., uplink transmission, downlink transmission, uplink reception, downlink reception) in a conventional 5G system. For example, a user plane function (UPF), which is an entity of the core network, can map service data flows (e.g., video, VoIP, Best Effort, etc.) received from a data network (DN) to (each) QoS flows. And, for example, the UPF can organize one or more QoS flows into a single PDU session. For example, a gNB (or the gNB's SDAP) can map the QoS flows for service data received from the UPF to the DRB. In this case, for example, the gNB (or the gNB's SDAP) can map one QoS flow to one DRB, or map multiple QoS flows to one DRB.

[0132] Meanwhile, when there is logical channel data and / or MAC CE and / or control messages (e.g., PC5-S message, PC5 RRC message) to be transmitted, the terminal can perform the LCP (logical channel prioritization) procedure according to the priority order.

[0133] The LCP procedure may be as follows. For example, when a terminal has multiple messages or data to be transmitted (e.g., MAC CE, communication data, (PC5) RRC message), it may generate a MAC PDU first for the message with the highest priority based on priority. For example, when the terminal has a MAC CE and data to be transmitted, if the destinations of the MAC CE and the data are different, it may generate a MAC PDU by multiplexing the message with the highest priority (e.g., MAC CE) into the MAC PDU first, and then accommodate the generated MAC PDU in the grant by using the allocated grant preferentially. Additionally, for example, if the destinations of the messages are the same, it may preferentially select the message with the highest priority to perform the multiplexing operation for generating the MAC PDU.

[0134] Meanwhile, in an ISAC, traffic for sensing services is generated and transmitted along with conventional communication service traffic, which can lead to flooding of traffic (e.g., communication service traffic and sensing service traffic) on the air interface. For example, in conventional LTE / NR systems, when communication service traffic becomes overloaded, the priority of traffic transmission is determined based on the logical channel priority among communication service traffics, thereby resolving the traffic overload problem by preferentially transmitting logical channel data with higher priority. However, conventional technology does not support priority determination rules among traffics belonging to the same logical channel. Therefore, there is no mechanism to resolve traffic overload in an ISAC when it occurs for sensing signals (e.g., sensing reference signals) and / or sensing data (e.g., sensing measurement data) for sensing services that have the same logical channel priority.

[0135] Additionally, the sensing device needs to transmit sensing measurement data to a core network entity and / or a sensing service provider. At this time, the initial sensing measurement data measured by the sensing device (e.g., data obtained by receiving a sensing reference signal and extracting sensing results for a target object) may be raw data that has not been processed (e.g., compression or removal of information not suitable for the purpose of the target sensing service). Furthermore, the sensing device may generally process the data collected by measuring the sensing signal and transmit it to the core network entity. Therefore, from the perspective of general sensing measurement data, the amount of raw data that has not been processed may be greater than (or larger than) the amount of processed data. In addition, the processing of sensing measurement data may be performed by the sensing device, but the sensing device may also transmit the raw data collected by monitoring the sensing signal to a base station or core network entity (e.g., a sensing function (SF) and / or a sensing service provider's server (e.g., a sensing service provider server)), and the base station or core network entity may process this raw data to generate the final sensing measurement data. Furthermore, communication service traffic data is generally mostly processed data (e.g., compressed or removed of unnecessary content), and in the event of traffic overload, the transmission priority of the processed communication service traffic may be determined based on the logical channel priority of the communication service traffic.

[0136] However, since ISAC must support both communication and sensing services, traffic overload can occur frequently. In conventional communication services, the transmission priority of processed data (e.g., PDU (protocol data unit)) was determined based on the QoS priority of that data (e.g., logical channel priority based on QoS requirements). However, in sensing services, it is common to transmit not only processed data but also raw data (e.g., unprocessed sensing measurement data). Alternatively, for example, raw data may have a larger data volume than processed data. Additionally, for example, in the case of sensing measurement raw data, the sensing device may not directly process the sensing measurement raw data but merely transmit the measured sensing raw data to a base station and / or core network entity (e.g., a sensing function (SF) and / or a sensing service provider's server (e.g., a sensing service provider server)), and the base station and / or core network entity (e.g., a sensing function (SF) and / or a sensing service provider's server (e.g., a sensing service provider server)) may process the sensing raw data to generate a final sensing measurement data result. Therefore, it may not be desirable to determine the transmission priority of the data based on the QoS or logical channel priority of the processed communication service data. Therefore, a mechanism for determining transmission priority between communication service traffic (e.g., processed data) and sensing service traffic (e.g., processed sensing measurement data or sensing measurement data based on unprocessed raw data) may be required.

[0137] In summary, according to conventional technology, the transmission priority of data can only be determined based on QoS priority (or logical channel priority), and cannot take into account the characteristics of the sensing data (e.g., whether the sensing data is processed, the volume of the sensing data, the importance of the sensing data, the latency sensitivity of the sensing data, etc.). Furthermore, although sensing data and communication data may coexist in ISAC, if only logical channel priority is considered as in the case where only communication data exists, urgent sensing data may be transmitted later than communication data, or large volumes of non-urgent sensing data may be transmitted unnecessarily first. In this case, for example, QoS requirements related to the sensing data may not be guaranteed. Alternatively, for example, problems such as network overload and / or waste of wireless resources may occur.

[0138] In this disclosure, a method for determining priority for transmitting sensing measurement data in an ISAC and an apparatus supporting the same are proposed.

[0139] In this disclosure, a procedure for determining the transmission priority between communication service traffic (e.g., processed data) and sensing service traffic (e.g., processed sensing measurement data or sensing measurement data based on unprocessed raw data) is proposed as follows.

[0140] For example, a network entity operated by a sensing service provider may request measurement results for a specific sensing service from a sensing device (via a base station). In this case, for example, when requesting sensing measurement data results, the network entity operated by the sensing service provider may request processed sensing measurement data or unprocessed sensing measurement data.

[0141] For example, when transmitting processed sensing measurement data, the transmission priority determination rule between communication service data and sensing data based on unprocessed raw data may be as follows.

[0142] For example, the determination of the transmission priority (or PDU generation priority) for processed communication service traffic can be based on the logical channel priority (or QoS requirements or service priority) of the communication service traffic.

[0143] For example, the determination of the transmission priority (or PDU generation priority) for processed sensing data (e.g., processed sensing measurement data) among sensing service traffic may be based on the logical channel priority (or QoS requirements or service priority) of the sensing service traffic (e.g., sensing measurement data and / or sensing reference signal).

[0144] For example, the determination of the transmission priority (or PDU generation priority) for raw sensing data (e.g., processed sensing measurement data) among sensing service traffic may be based on the transmission priority level (e.g., "urgent" / "not urgent" or "high importance" / "low importance") transmitted by the core network or base station. For example, if the transmission priority level is "urgent" or "high importance," the transmission priority may be considered the highest priority (or may have the same priority as the highest priority among logical channel priorities (or service priorities)). For example, if the transmission priority level is "not urgent" or "low importance," the transmission priority (or PDU generation priority) can be compared and determined with other data (e.g., communication service data or sensing service data) based on the logical channel priority (or service priority) associated with the service (or, if it is "not urgent" or "low importance," the transmission priority (or PDU generation priority) of sensing measurement data based on the raw data of the sensing service can be considered as having the same priority as the lowest priority among the logical channel priority or the service priority).

[0145] Alternatively, for example, a core network entity performing a sensing service management function (e.g., a sensing function (SF) and / or a management server of a sensing service provider) may transmit the transmission priority level of the raw data for the sensing service to be received (e.g., "urgent" / "not urgent" or "high importance" / "low importance") to the base station and / or the sensing device upon a request for sensing measurement data based on unprocessed raw data. For example, if the transmission of communication service data, processed sensing measurement data related to the sensing service, and unprocessed sensing measurement data occurs simultaneously from the sensing device, the data transmission priority (or PDU generation priority) may be determined by applying the following rules.

[0146] For example, if a sensing device receives a request for raw data-based sensing measurement data from a base station and / or a core network entity (e.g., a network server where a sensing function (SF) or a sensing service is operated) and transmits the sensing measurement data, and the transmission priority level of the raw data-based sensing measurement data of the requested sensing service is "urgent" or "high importance," and a situation arises where communication service traffic and / or the transmission of processed sensing service measurement data overlap, the raw data-based sensing measurement data with a priority level of "urgent" or "high importance" may be considered as having the highest transmission priority (or, the highest PDU generation priority), and the raw data-based sensing measurement data may be transmitted first (or, it may be considered to have the same priority as the highest priority among logical channel priorities (or service priorities)).

[0147] For example, if a sensing device receives a request for raw data-based sensing measurement data from a base station or core network entity (e.g., a network server where a sensing function (SF) or sensing service is operated) and transmits the sensing measurement data, and the transmission priority level (or PDU generation priority) of the requested raw data-based sensing measurement data is "not urgent" or "low importance," and a situation arises where communication service traffic and / or the transmission of processed sensing service measurement data overlap, the logical channel priority associated with the raw data-based sensing measurement data with a priority level of "not urgent" or "low importance" may be compared with the logical channel priority of the remaining transmitted data (e.g., communication service data or processed sensing measurement data), and the transmission of the data with the highest priority may be performed preferentially (or, if it is "not urgent" or "low importance," the sensing service The transmission priority (or PDU generation priority) of raw data-based sensing measurement data can be considered to have the same priority as the lowest priority among logical channel priority or service priority.

[0148] FIG. 11 illustrates a method for transmitting sensing data based on a priority set in the sensing data, 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.

[0149] Referring to FIG. 11, in step S1110, UE 1 can acquire sensing data. For example, UE 1 can acquire sensing data based on sensing. Or, for example, if UE 1 performs monostatic sensing, it can acquire sensing data based on the transmission and reception of a sensing signal. Or, for example, if UE 1 performs bistatic sensing, it can acquire sensing data based on the reception of a sensing signal. For example, UE 1 can acquire sensing data by performing sensing based on receiving a request for sensing data for a sensing service from a network entity (or SF (sensing function), or server) that manages the sensing service.

[0150] In step S1120, UE 1 can check the priority of the sensing data (e.g., transmission priority). For example, UE 1 can check the priority set for the sensing data (e.g., transmission priority). For example, the priority set for the sensing data (e.g., transmission priority) can be set to either high or low. Or, for example, the priority set for the sensing data (e.g., transmission priority) can be set to either urgent or not-urgent. Or, for example, the priority set for the sensing data (e.g., transmission priority) can be set to either high importance or low importance. For example, as described above, the priority of the sensing data (e.g., transmission priority) can be set binary. For example, the priority of the sensing data (e.g., transmission priority) described above can be defined as a new priority different from the priority set for a conventional logical channel. For example, the priority of sensing data (e.g., transmission priority) may be set by a network entity (or SF (sensing function), or server) managing the sensing service. Or, for example, the priority of sensing data (e.g., transmission priority) may be set by a network entity (or SF (sensing function), or server) managing the sensing service based on information (or requirements) related to the sensing service. Or, for example, UE 1 may receive information related to the priority of sensing data set by a network entity (or SF (sensing function), or server) managing the sensing service.

[0151] In step S1130, based on the fact that the priority of the sensing data (e.g., transmission priority) is set to high (or urgent) or high importance, UE 1 may transmit the sensing data to UE 2 with the highest priority. Alternatively, for example, based on the fact that the priority of the sensing data (e.g., transmission priority) is set to high (or urgent) or high importance, UE 1 may transmit the sensing data without performing a comparison (e.g., LCP procedure) of the priority of the logical channel to which the sensing data is mapped (e.g., priority set on the logical channel to which the sensing data is mapped). Alternatively, for example, based on the fact that the priority of the sensing data (e.g., transmission priority) is set to high (or urgent) or high importance, UE 1 may regard the priority of the logical channel to which the sensing data is mapped (e.g., priority set on the logical channel to which the sensing data is mapped) as the highest priority. Alternatively, for example, based on the fact that the priority of the sensing data (e.g., transmission priority) is set to high (or urgent, or high importance), UE 1 may transmit the sensing data preferentially over the communication data, even if there is communication data mapped to the logical channel with the highest priority.

[0152] FIG. 12 illustrates a method for transmitting sensing data based on a priority set in the sensing data, 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.

[0153] Referring to FIG. 12, in step S1210, UE 1 can acquire sensing data. For example, UE 1 can acquire sensing data based on sensing. Or, for example, if UE 1 performs monostatic sensing, it can acquire sensing data based on the transmission and reception of a sensing signal. Or, for example, if UE 1 performs bistatic sensing, it can acquire sensing data based on the reception of a sensing signal. For example, UE 1 can acquire sensing data by performing sensing based on receiving a request for sensing data for a sensing service from a network entity (or SF (sensing function), or server) that manages the sensing service.

[0154] In step S1220, UE 1 can check the priority of the sensing data (e.g., transmission priority). For example, UE 1 can check the priority set for the sensing data (e.g., transmission priority). For example, the priority set for the sensing data (e.g., transmission priority) can be set to either high or low. Or, for example, the priority set for the sensing data (e.g., transmission priority) can be set to either urgent or not-urgent. Or, for example, the priority set for the sensing data (e.g., transmission priority) can be set to either high importance or low importance. For example, as described above, the priority of the sensing data (e.g., transmission priority) can be set binary. For example, the priority of the sensing data (e.g., transmission priority) described above can be defined as a new priority different from the priority set for a conventional logical channel. For example, the priority of sensing data (e.g., transmission priority) may be set by a network entity (or SF (sensing function), or server) managing the sensing service. Or, for example, the priority of sensing data (e.g., transmission priority) may be set by a network entity (or SF (sensing function), or server) managing the sensing service based on information (or requirements) related to the sensing service. Or, for example, UE 1 may receive information related to the priority of sensing data set by a network entity (or SF (sensing function), or server) managing the sensing service.

[0155] In step S1230, based on the fact that the priority of the sensing data (e.g., transmission priority) is set to low (or not-urgent, or low importance), a comparison can be performed between the priority of the logical channel to which the sensing data is mapped (e.g., priority set on the logical channel to which the sensing data is mapped) and the priority of the logical channel related to the communication data (e.g., priority set on the logical channel to which the communication data is mapped) (e.g., LCP procedure).

[0156] In step S1240, UE 1 can transmit sensing data to UE 2 based on the fact that the priority of the logical channel to which the sensing data is mapped (e.g., priority set on the logical channel to which the sensing data is mapped) is higher than the priority of the logical channel related to the communication data (e.g., priority set on the logical channel to which the communication data is mapped). Alternatively, for example, although not illustrated in FIG. 12 for convenience of explanation, UE 1 can transmit communication data to UE 2 based on the fact that the priority of the logical channel to which the sensing data is mapped (e.g., priority set on the logical channel to which the sensing data is mapped) is lower than the priority of the logical channel related to the communication data (e.g., priority set on the logical channel to which the communication data is mapped). For example, based on the fact that the priority of the sensing data (e.g., transmission priority) is set to low (or not-urgent, or low importance), the priority of the logical channel to which the sensing data is mapped (e.g., priority set on the logical channel to which the sensing data is mapped) can be considered the lowest priority.

[0157] The embodiment(s) of the present disclosure can be extended and applied to all six sensing scenarios of FIG. 9 described above.

[0158] For example, the applicability of (some) proposed methods / rules of this disclosure and / or related parameters (e.g., thresholds) may be set specifically to resource pools (or differently or independently). For example, the applicability of (some) proposed methods / rules of this disclosure and / or related parameters (e.g., thresholds) may be set specifically to congestion levels (or differently or independently). For example, the applicability of (some) proposed methods / rules of this disclosure and / or related parameters (e.g., thresholds) may be set specifically to service priorities or service types (or differently or independently). For example, the applicability of (some) proposed methods / rules of this disclosure and / or related parameters (e.g., thresholds) may be set specifically to QoS requirements (e.g., latency, reliability) or QoS profiles or PQIs (or differently or independently). For example, the applicability of (some) proposed methods / rules of the present disclosure and / or related parameters (e.g., thresholds) may be set specifically (or differently or independently) to a traffic type (e.g., periodic or non-periodic generated traffic).

[0181] Referring to FIG. 14, in step S1410, the second device may request sensing data related to a sensing service from the first device. In step S1420, the second device may transmit information related to the priority of the sensing data to the first device. For example, the priority of the sensing data may be set to high or low.

[0182] The proposed method above may be applied to a device according to various embodiments of the present disclosure. First, the processor (202) of the second device (200) may control the transceiver (206) to request sensing data related to a sensing service from the first device. Then, the processor (202) of the second device (200) may control the transceiver (206) to transmit information related to the priority of the sensing data to the first device.

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 execution by the at least one processor, the instructions may cause the second device to: request sensing data related to a sensing service from the first device; and transmit information related to the priority of the sensing data to the first device.

[0186] According to various embodiments of the present disclosure, when transmitting sensing data based on priority, a two-step priority comparison / verification can be performed. Alternatively, the transmission priority of the sensing data may not rely solely on the logical channel priority, but may instead prioritize a new priority that takes into account the characteristics of the sensing data. Specifically, for example, if the priority of the sensing data newly defined in the present disclosure is set to urgent or high importance, the sensing data can be transmitted preferentially over the communication data even if the priority of the logical channel related to the sensing data is lower than the priority of the logical channel related to the communication data, thereby ensuring the quality of the sensing service. Alternatively, for example, if the priority of the sensing data newly defined in the present disclosure is set to not-urgent or low importance, the priority of the logical channel related to the sensing data and the priority of the logical channel related to the communication data can be compared according to the existing LCP procedure, thereby preventing the waste of wireless resources caused by the transmission of unnecessary large volumes of sensing data and ensuring the stability of the network.

[0204] FIG. 17 illustrates a signal processing circuit for a transmission signal according to one embodiment of the present disclosure. The embodiment of FIG. 17 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.

[0205] Referring to FIG. 17, 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. 17 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 16. The hardware elements of FIG. 17 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 16. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 16. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 16, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 16.

[0206] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 17. 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).

[0207] 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.

[0208] 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.

[0209] 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. 17. For example, a wireless device (e.g., 100, 200 in FIG. 16) 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.
