[0050] FIG. 1 illustrates a device-to-device communication procedure 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, proposals, methods, and / or operations of the embodiments may be omitted.

[0051] Referring to FIG. 1, in step S101, a first device and a second device can perform synchronization. For example, the first device can be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device can 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 can perform an initial cell search operation. For example, the first device can detect at least one synchronization signal transmitted by the second device according to a predefined rule. Here, for example, the synchronization signal can include a plurality of synchronization signals classified according to a structure or purpose (e.g., a primary synchronization signal, a secondary synchronization signal, etc.). 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., a cell identifier).

[0052] In step S103, the first device can obtain system information transmitted by the second device. For example, the system information may include information related to the properties, characteristics, and / or capabilities of the second device required 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 system information before receiving the system information. For example, the request and provision of system information may be performed after a random access procedure described below.

[0053] In step S105, the first device and the second device can perform a random access procedure. For example, the first device can transmit and / or receive at least one message (e.g., a random access preamble, a random access response message, etc.) for the random access procedure based on information related to a 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 can transmit a preamble (e.g., Msg1) through the random access channel, the first device can receive a random access response message (e.g., Msg2), the first device can transmit a message (e.g., Msg3) including 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 can receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be sent and received as one message (e.g., MsgA), and / or Msg2 and Msg4 can be sent and received as one message (e.g., MsgB).

[0054] 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 that controls a connection (e.g., a radio resource control (RRC) layer), a layer that handles mapping between logical channels and transport channels (e.g., a media access control (MAC) layer), a layer that handles physical channels (e.g., a physical (PHY) layer), etc. For example, the first device and the second device may perform at least one of signaling for establishing a connection, signaling for determining settings related to communication, and / or signaling for indicating allocated resources. For example, the control information may be signaled / transmitted via 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.

[0055] 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, transmit, and / or receive data based on signaling of control information. 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, waveform demodulation for each antenna, signal arrangement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0056] For example, the layers of a radio interface protocol between a first device and a second device can be divided into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, a physical layer belonging to the first layer can provide an information transfer service using a physical channel, and an RRC (radio resource control) layer located in the third layer can play a role in controlling radio resources between the first device and the second device. For this purpose, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0057] FIG. 2 illustrates a radio protocol architecture according to an 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 the embodiments may be omitted. For example, (a) of FIG. 2 may illustrate a radio protocol stack of a user plane for uplink communication or downlink communication, and (b) of FIG. 2 may illustrate a radio protocol stack of a control plane for uplink communication or downlink communication. For example, (c) of FIG. 2 may illustrate a radio protocol stack of a user plane for device-to-device communication, and (d) of FIG. 2 may illustrate a radio protocol stack of a control plane for device-to-device communication.

[0058] For example, the physical layer can provide information transmission services to upper layers using physical channels. For example, the physical layer can be connected to the upper layer, the medium access control (MAC) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through the transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted over the wireless interface. For example, data can be transmitted between different physical layers, for example, between the physical layers of a first device and a second device, through a physical channel. For example, the physical channel can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and time and frequency can be utilized as radio resources.

[0059] For example, the MAC layer can provide services to the upper layer, the radio link control (RLC) layer, through logical channels. For example, the MAC layer can provide a mapping function from multiple logical channels to multiple transport channels. For example, the MAC layer can provide a logical channel multiplexing function by mapping multiple logical channels to a single transport channel. For example, the MAC sublayer can provide data transmission services on logical channels.

[0060] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee the various quality of service (QoS) required by radio bearers (RBs), the RLC layer can provide three operating modes: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat request (ARQ).

[0061] For example, the RRC (radio resource control) layer can be defined only in the control plane. For example, the RRC layer can be responsible for controlling logical channels, transport channels, and physical channels in relation to the configuration, re-configuration, and release of radio bearers. For example, an RB can mean a logical path provided by a first layer (e.g., a physical layer) and a second layer (e.g., a MAC layer, an RLC layer, a PDCP (packet data convergence protocol) layer, a SDAP (service data adaptation protocol) layer, etc.) for data transmission between a first device and a second device.

[0062] For example, the functions of the PDCP layer in the user plane may include forwarding of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include forwarding of control plane data and ciphering / integrity protection.

[0063] For example, establishing an RB can refer to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. For example, RBs can be divided into two types: signaling radio bearers (SRBs) and data radio bearers (DRBs). For example, SRBs can be used as a channel to transmit RRC messages in the control plane, while DRBs can be used as a channel to transmit user data in the user plane.

[0064] For example, if an RRC connection is established between the RRC layer of the terminal and the RRC layer of the base station, the terminal will be in the RRC_CONNECTED state, and if not, it may be in the RRC_IDLE state. For example, in the case of NR, the RRC_INACTIVE state is additionally defined, and a terminal in the RRC_INACTIVE state can release the connection with the base station while maintaining the connection with the core network.

[0065] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) for transmitting system information, and / or a downlink shared channel (SCH) for transmitting user traffic or control messages. For example, traffic or control messages of a downlink multicast or broadcast service may be transmitted through the downlink SCH, or may be transmitted through a separate downlink multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) for transmitting initial control messages, and / or an uplink shared channel (SCH) for transmitting user traffic or control messages. For example, a logical channel located above a 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).

[0066] FIG. 3 illustrates the structure of a wireless frame according to an 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.

[0067] Referring to FIG. 3, for example, a radio frame may be used 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 include 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 according to a subcarrier spacing (SCS). For example, each slot may include 12 or 14 OFDM (A) symbols, depending on a cyclic prefix (CP).

[0068] For example, when normal CP is used, each slot can contain 14 symbols. For example, when extended CP is used, each slot can contain 12 symbols. Here, for example, the symbols can contain OFDM symbols (or CP-OFDM symbols), SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0069] Table 2 below shows the number of symbols per slot (N) depending on 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 ) is an example.

[0070] CP type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slotNormal CP15kHz (u=0)1410130kHz (u=1)1420260kHz (u=2)14404120kHz (u=3)14808240kHz (u=4)1416016Extended CP60kHz (u=2)12404

[0071] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single terminal. Accordingly, the (absolute time) interval of time resources (e.g., subframes, slots, or transmit time intervals (TTIs)) composed of the same number of symbols may be set differently between the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTIs, etc. may be referred to as time units.

[0072] For example, multiple numerologies, or SCSs, may be supported to support various services. For example, a 15 kHz SCS may support wide areas in traditional cellular bands, while a 30 kHz / 60 kHz SCS may support dense urban areas, lower latency, and wider carrier bandwidth. For example, a 60 kHz or higher SCS may support bandwidths greater than 24.25 GHz to overcome phase noise.

[0073] FIG. 4 illustrates a slot structure of a frame according to an 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, proposals, methods, and / or operations of the embodiments may be omitted.

[0074] 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 one numerology (e.g., SCS, CP length, etc.). For example, a carrier may include at most N BWPs (where N is a positive integer). For example, data communication may be performed through an activated BWP. For example, each element may be referred to as a resource element (RE) in the resource grid, and one complex symbol may be mapped to it.

[0075] For example, a BWP may be a contiguous set of PRBs in a given numerology. For example, a PRB may be selected from a contiguous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0076] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the UE may not monitor the downlink radio link quality in a DL BWP other than the active DL BWP on the PCell (primary cell). For example, the UE may not receive a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), or a channel state information-reference signal (CSI-RS) (except for radio resource management (RRM)) outside of the active DL BWP. For example, the UE may not trigger channel state information (CSI) reporting for an inactive DL BWP. For example, the UE may not transmit a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) outside of the active UL BWP. For example, for downlink, the initial BWP can be given as a set of consecutive resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For uplink, for example, 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 a higher layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if a terminal does not detect DCI (downlink control information) for a certain period of time, the terminal may switch its active BWP to a default BWP.

[0077] 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.

[0078] Referring to FIG. 5, for example, a common resource block (CRB) may be a carrier resource block numbered from one end of a 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 a resource block grid.

[0079] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP ) can be set by. For example, point A can be an outer reference point of the PRB of a carrier where subcarrier 0 of all numerologies (e.g., all numerologies supported by the network on that carrier) aligns. For example, the offset can be the PRB spacing between the lowest subcarrier in a given numerology and point A. For example, the bandwidth can be the number of PRBs in a given numerology.

[0080] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to an 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 the embodiments may be omitted.

[0081] As core implementation technologies of the 6G system, 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.

[0082] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. For example, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a crucial role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. AI can also facilitate rapid communication in brain-computer interfaces (BCIs). 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.

[0083] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by using sub-THz communication with wide bandwidths and applying advanced massive MIMO technology. THz waves, also known as sub-millimeter waves, typically refer to the frequency range between 0.1 THz and 10 THz, with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz to 300 GHz band (sub-THz band) is considered a key part of the THz spectrum for cellular communications. Adding the sub-THz band to the mmWave band will increase the capacity of 6G cellular communications. Among the defined THz bands, 300 GHz to 3 THz lies in the far infrared (IR) frequency band. While part of the optical band, the 300 GHz to 3 THz band lies at the boundary of the optical band, immediately following the RF band. Therefore, this 300 GHz to 3 THz band exhibits similarities to RF. Key characteristics of THz communications include (i) the widely available bandwidth to support very high data rates and (ii) the high path loss that occurs at high frequencies (requiring highly directional antennas). The narrow beamwidths generated by highly directional antennas reduce interference. The small wavelength of THz signals allows for a significantly larger number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array technologies to overcome range limitations.

[0097] 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 can include UAM, RAM, UAS, and uncrewed aerial vehicles (UAVs).

[0098] - Autonomous driving (self-driving): V2X (vehicle to everything), a key element in building autonomous driving infrastructure, can be a technology that allows cars to communicate and share with various elements on the road for autonomous driving, such as vehicle to vehicle (V2V) wireless communication and vehicle to infrastructure (V2I) wireless communication.

[0099] Non-terrestrial network (NTN): NTN can refer to a network or network segment that utilizes radio frequency (RF) resources mounted on satellites (or UAS platforms). NTN services may be considered to secure wider coverage or provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0100] - Integrated sensing and communication (ISAC): Wireless sensing is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the characteristics of the environment and / or objects within the environment.

[0101] - Reconfigurable intelligent surface (RIS): RIS can be used to manipulate and enhance signal propagation in wireless communication environments. For example, a 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 example, a RIS can improve signal reception by controlling the path, phase, and / or intensity of the propagating signal. For example, in the case of a RIS, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For example, because a RIS can be reconfigured to suit different environments, it can meet various communication requirements and operate effectively in dynamic network environments.

[0102] 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.

[0103] Referring to FIG. 7, NTN communication can be performed based on satellite networks, high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS), and terminals capable of aerial communication (e.g., AAMs). For example, to improve coverage, etc., devices such as satellite networks, HIBS, and terminals capable of aerial communication (e.g., AAMs) 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.

[0104] For example, a terminal can obtain information about the environment and / or the characteristics of objects within the environment by using radio frequency sensing to determine the instantaneous linear velocity, angle, distance (range), etc. of an object. Since radio frequency sensing does not require a device to connect to the object through a network, it can provide a service for object positioning without a device. The ability to obtain range, velocity, and angle information from radio frequency signals can enable a wide range of new capabilities, such as various object detection, object recognition (e.g., vehicles, humans, animals, UAVs), and high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to a variety of industries (e.g., unmanned aerial vehicles, smart homes, V2X, factories, railways, public safety, etc.), enabling applications that provide, for example, intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, health and traffic management, and more. In some cases, wireless sensing can utilize non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP-based sensing. For example, the operation of wireless sensing services, e.g., sensing operations, may depend on the transmission, reflection, and scattering of wireless sensing signals. Therefore, wireless sensing offers an opportunity to enhance existing communication systems from a communications network to a wireless communication and sensing network.

[0105] FIG. 8 illustrates an example of a sensing operation according to an embodiment of the present disclosure. The embodiment of FIG. 8 can 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. Specifically, (a) of FIG. 8 illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and (b) of FIG. 8 illustrates an example of sensing using a separated sensing receiver and sensing transmitter (e.g., bistatic sensing).

[0106] Referring to FIG. 8, a sensing transmitter can transmit a sensing signal for sensing one or more objects (and / or an environment around the objects). For example, the sensing signal can be a radio (frequency) signal defined to be transmittable by a base station / terminal. For example, a sensing receiver can receive a signal scattered / reflected by one or more objects (and / or an environment around the objects) from a sensing signal transmitted from the sensing transmitter. For example, in the sensing receiver, sensing data can be derived from the scattered / reflected signal, and a sensing result can be generated / obtained through processing the sensing data. Here, for example, the sensing result can include characteristic information (e.g., position, distance, speed, angle, etc.) about one or more objects (and / or an environment around the objects). For example, the sensing results generated / obtained in this way may be utilized for wireless sensing services (e.g., detection, tracking, etc. of objects and / or environments) or provided / disclosed to a trusted third party.

[0107] For example, a sensing transmitter may be a base station or terminal that transmits a sensing signal to be used for a sensing service to operate, and the sensing transmitter may be located in the same or different base station or terminal as a sensing receiver. For example, a sensing receiver may be a base station or terminal that receives a sensing signal to be used for a sensing service to operate, and the sensing receiver may be located in the same or different base station or terminal as a sensing transmitter. For example, a sensing target may be an object to be detected by deriving characteristics of an object in the environment from a sensing signal. For example, a background environment may be a background that is not a sensing target (e.g., clutter, environmental objects, etc.). For example, an environment object may be an object whose location is known other than a sensing target. For example, monostatic sensing may be sensing in which a sensing transmitter and a sensing receiver coexist in the same base station or terminal. For example, bistatic sensing may be sensing in which the sensing transmitter and the sensing receiver are located in different base stations or terminals. For example, multistatic sensing may be sensing in which there are multiple sensing transmitters and / or multiple sensing receivers for a (single) sensing target. For example, monostatic sensing, bistatic sensing, and / or multistatic sensing may be distinguished based on the angle between the sensing transmitter, the sensing target, and the sensing receiver. For example, if the angle between the sensing transmitter, the sensing target, and the sensing receiver is less than or equal to a threshold, it may be defined as monostatic sensing or semi-monostatic sensing. For example, if the angle between the sensing transmitter, the sensing target, and the sensing receiver is greater than or equal to a threshold, it may be defined as bistatic sensing or multistatic sensing.For example, the terminal may transmit a sensing signal over a wireless interface that can be used for sensing purposes. For example, the terminal may transmit a sensing signal over a 3GPP wireless interface that can be used for sensing purposes.

[0108] For example, the common framework of the ISAC channel model can be composed of target channel components and background channel components. For example, this can be obtained based on mathematical equation 1.

[0109]

[0110] Here, for example, target channel H target may include all [multipath] components affected by the sensing target. For example, background channel H Background may contain other [multipath] components that do not belong to the target channel.

[0111] For example, radar cross-section (RCS) may be a measure of how well a radar sensor can detect a target. Therefore, it is often referred to as an electromagnetic characteristic of the target. For example, a larger RCS may indicate that the target is more easily detectable. For example, in a radar sensor measurement, power may be transmitted toward the target, and the target may reflect some of the power back to the receiver. For example, the received power may be based on the RCS of the target, among other factors. For example, the received power may be proportional to the RCS. For example, the RCS of a target may be based on at least one of the frequency of the radar signal, the target material, the target shape, the target size, the direction of the incident and reflected waves relative to the target, the target movement, and / or the target illumination.

[0112] FIG. 9 illustrates the relationship between RCS, range (D), and power 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, proposals, methods, and / or operations of the embodiments may be omitted.

[0113] Referring to Figure 9, the RCS of a radar target may be a virtual area required to intercept the power density transmitted from the target. For example, the relevant radar mathematical formula may be defined as in Equation 2.

[0114]

[0115] Here, for example, P TX can be the transmitter power [W], and G TXcan be the gain of the transmitting antenna [dimensionless], D can be the distance between the equipment under test (EUT) and the target [m], and RCS can be the radar cross section [m 2 ] can be, P RX can be the power [W] received back by the EUT from the object, and A eff is the effective area of ​​the receiving antenna [m 2 ] can be. For example, A eff can be obtained based on mathematical formula 3.

[0116]

[0117] Here, for example, G RX can be the gain of the receiving antenna [dimensionless], λ can be the wavelength of the radio signal [m], λ = c / f, c can be the speed of light 299792458 [m / s], and f can be the frequency [Hz].

[0118] For example, if the transmitter and receiver are co-located and the same antenna is used for both transmission and reception (G TX = G RX = G), the related radar mathematical formula can be defined as in mathematical formula 4.

[0119]

[0120] Here, for example, P TX can be the transmitter power [W], G can be the gain of the transmitting antenna [dimensionless], D can be the distance between the equipment under test (EUT) and the target [m], and RCS can be the radar cross section [m 2 ] can be, P RX can be the power [W] received back by the EUT from the object.

[0121] FIG. 10 illustrates an example of a protocol layer used to support transmission of an LTE positioning protocol (LPP) message between a location management function (LMF) and a UE, according to an 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 the embodiments may be omitted.

[0122] LPP PDUs can be transmitted via non-access stratum (NAS) PDUs between an access and mobility management function (AMF) and a UE. Referring to FIG. 10, LPP can be terminated between a target device (e.g., a UE in the control plane or a secure user plane location (SUPL) enabled terminal (SET) in the user plane) and a location server (e.g., an LMF in the control plane or a secure user plane location (SUPL) location platform (SLP) in the user plane). LPP messages can be conveyed in the form of transparent PDUs over an intermediate network interface using a suitable protocol, such as NGAP (NG application protocol) over the NG-C (NG-control plane) interface, NAS / RRC over the LTE-Uu and NR-Uu interfaces. The LPP protocol enables positioning for NR and LTE using various positioning methods.

[0123] For example, a target device and a location server can exchange capability information, positioning assistance data, and / or location information via the LPP protocol. For example, LPP messages can be used to exchange error information and / or indicate the termination of an LPP procedure.

[0171] Previously, NR positioning up to Release 17 could only support network-based Uu positioning, which performed location search under the connection between the target UE and the network (gNB / LMF). Meanwhile, starting from NR Release 18, sidelink positioning (SL positioning) using sidelink communication can be supported. Sidelink positioning can be a new method that can perform positioning operations by exchanging positioning reference signals through a direct connection with anchor UEs around the target UE, rather than the base station. Positioning operations at the physical layer can be performed by transmitting and measuring SL PRS (sidelink positioning reference signal) between the target UE and the anchor UE.

[0172] Uu positioning can use the LPP protocol. An LPP session can be a point-to-point communication protocol between a target UE and an LMF. Through the LPP protocol, the target UE can receive positioning information from the LMF. The LMF can configure the target UE and the base station (gNB) through the LPP protocol and the NRPPa protocol, exchange positioning-related messages, and perform positioning operations. Meanwhile, in Release 18 sidelink positioning, positioning operations can be performed by exchanging sidelink positioning protocol messages with the target UE, server UE (or LMF), and anchor UEs. Sidelink positioning can use the sidelink positioning protocol (SLPP) to configure and exchange messages between UEs.

[0173] Positioning methods (e.g., sidelink positioning) require the target to possess a communication terminal, and signaling messages must be exchanged between the transmitter and the target for position measurement. This increases the overhead of signal processing between the target and the transmitter, and fundamentally limits positioning if the target does not possess a separate communication terminal.

[0174] In contrast, Integrated Sensing and Communication (ISAC) can accurately detect the presence and movement of a target, regardless of whether the target is carrying a communication terminal. Furthermore, it can reliably acquire detailed sensing information, such as the target's distance, speed, and angle. ISAC can estimate the target's characteristics simply by analyzing the information reflected from the target's signal emitted by the transmitter, without requiring a separate response signal or message from the target. Accordingly, ISAC significantly reduces the amount of signaling compared to positioning methods, significantly lowering overhead and enabling more efficient and flexible sensing and communication operations simultaneously.

[0175] FIG. 11 illustrates an example of an ISAC service according to an 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, proposals, methods, and / or operations of the embodiments may be omitted.

[0176] Referring to Figure 11, examples of various application areas where ISAC can be applied are illustrated. Specifically, ISAC can support predictive maintenance and employee localization and authorization in smart manufacturing and industrial IoT, and provide weather prediction, pollution monitoring, rain monitoring, and insect monitoring in environmental monitoring.

[0177] Additionally, in the field of Sensing as a Service, it can be utilized in drone monitoring and management, mobile crowd sensing, channel knowledge map construction, and cooperative localization and imaging.

[0178] Furthermore, in the field of remote sensing, it can support satellite imaging and broadcasting, drone swarm SAR imaging, and in the field of smart homes, it can be utilized for human proximity detection, spatial-aware control, sensing-aided wireless charging, fall detection, and vital signal monitoring.

[0179] Additionally, in the field of human-computer interaction (HCI), it enables gesture recognition, keystroke recognition, and arm / head activity recognition, and in the field of vehicle-to-everything (V2X) communication, it can provide various services such as high precision location, vehicle platooning, extended sensor, simultaneous localization and mapping, and secure hands-free access.

[0180] Integrated Sensing and Communication (ISAC) technology, which integrates target sensing and user communication functions in recent 6th-generation (6G) mobile communication systems, is attracting attention as a key standardization target. ISAC technology, as shown in Figure 11, is emerging as an essential technology in diverse industries, including autonomous driving, smart factories, drones, and healthcare, based on its advantages such as efficient frequency utilization, reuse of existing communication infrastructure, and cost savings due to integrated sensing and communication.

[0181] FIG. 12 illustrates various integrated sensing and communication (ISAC) systems according to an embodiment of the present disclosure. Specifically, (a) of FIG. 12 illustrates an example of a network-based monostatic ISAC system, (b) of FIG. 12 illustrates an example of a network-based bistatic ISAC system, and (c) of FIG. 12 illustrates an example of a network-UE-based bistatic ISAC system (①) and a network-coordinated UE bistatic ISAC system (①+②). In addition, (d) of FIG. 12 may show an example of a UE-based monostatic ISAC system, (e) of FIG. 12 may show an example of a UE-network bistatic ISAC system, and (f) of FIG. 12 may show an example of a UE-based bistatic ISAC system. The embodiment of FIG. 12 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. For example, the network may be a TRP. For example, the network may be a base station.

[0182] Referring to FIG. 12, various ISAC systems may be considered in the present disclosure to include various ISAC service embodiments. For example, in the present disclosure, a base station may be represented as a BS. For example, in the present disclosure, a terminal may be represented as a UE. For example, a transmitter may transmit a signal for sensing, and a receiver may perform sensing based on a signal reflected from an object. FIG. 12(a) may represent a network-based monostatic ISAC system. In this system, a BS transmits an ISAC signal to multiple targets and receives the reflected signal to estimate the distance and velocity of the targets. Here, the targets may be UEs. FIG. 12(b) may represent a network-based bistatic ISAC system. In this system, two BSs may cooperate to estimate the distance and velocity of the same multiple targets. BS 1 may be a transmitter and BS 2 may be a receiver. BS 2 may receive the ISAC signals transmitted by BS 1 that are reflected by targets. BS 2 may then estimate the distance and velocity of the targets. Unlike monostatic systems, bistatic ISAC systems may not have information about the transmitted signals. Therefore, bistatic ISAC systems can obtain radar information matrices of targets through pilot signals that are already known to both the transmitter and receiver. Figure 12 (c) may be a network-UE-based bistatic ISAC system. In this system, the BS may transmit an ISAC signal. The BS may use a beamforming technique to direct most of the reflected signals toward the UE or to return some of the reflected signals to the BS.In the former case, the UE can receive most of the signals transmitted by the BS and perform target range and velocity estimation. While this allows the UE to quickly obtain the necessary target information, the UE performs all the processing, potentially increasing computational complexity. In contrast, in the latter case, the BS first estimates the target range and velocity, similar to a monostatic ISAC system, and then, based on the estimation results, informs the UE of an appropriate target estimation technique. This allows the UE to immediately perform target estimation using the technique provided by the BS, thereby reducing complexity.

[0183] Figure 12(d) may be a UE-based monostatic ISAC system. The system can directly estimate the target range and velocity at the UE. Figure 12(e) may be a UE-network bistatic ISAC system. The BS can estimate the range and velocity of multiple targets by receiving the ISAC signal transmitted by the UE reflected from the target. Figure 12(f) may be a UE-based bistatic ISAC system. In the system, the range and velocity of targets can be estimated through bistatic between different UEs.

[0184] For example, in the present disclosure, a “specific threshold” may mean a threshold that is defined in advance or set (in advance) by a higher layer (including an application layer) of a network or a base station or a terminal. For example, in the present disclosure, a “specific set value” may mean a value that is defined in advance or set (in advance) by a higher layer (including an application layer) of a network or a base station or a terminal. For example, in the present disclosure, “set by the network / base station” may mean an operation in which the base station sets (in advance) to the UE via higher layer RRC signaling, sets / signals to the UE via MAC CE, or signals to the UE via DCI.

[0185] For example, in the present disclosure, a message may be interpreted as being replaced with at least one of a control message, a data message, a signal, a data signal, and / or a control signal.

[0186] For example, referring to a standard document, some procedures and technical specifications related to the present disclosure may be as follows.

[0187] For example, in this disclosure, several names are exemplary and may be replaced / considered as other names that perform the same / similar function based on what is described in each step (regardless of the name).

[0188] For example, actions for positioning QoS guarantees can be proposed.

[0189] In conventional Uu positioning, the LMF can inform the UE of the QoS value of the triggered positioning service. Then, the base station or UE can request resource allocation from the base station to satisfy the QoS. The UE or base station can transmit measured data to the LMF or UE to calculate the location and QoS value.

[0190] If the final calculated location and corresponding QoS do not meet the level required by the positioning service, the positioning service may be considered failed. Subsequently, new positioning operations may be performed using new services or new positioning methods.

[0191] Sidelink positioning can also perform operations to satisfy QoS in the same / similar manner as Uu positioning.

[0192] The problem is that the QoS values ​​for these positioning operations are calculated after the positioning service is calculated, i.e., based on the final result. For example, if QoS failure occurs, actions to ensure QoS, such as allocating more base stations or allocating more resources, are performed, resulting in positioning time delays.

[0193] For example, for sidelink positioning, an SL-PRS resource request MAC CE can be proposed.

[0194] In sidelink communication between UEs, independent communication links are established between peers, so it is necessary to distinguish data to be transmitted for each communication link, for example, by destination index (where, for example, each peer may have a different destination index value). Therefore, SL-BSR MAC CE was introduced, which is distinct from the conventional BSR.

[0195] FIG. 13 illustrates an example of a sidelink buffer status reporting MAC according to an embodiment of the present disclosure. The embodiment of FIG. 13 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.

[0196] Referring to FIG. 13, for example, the Sidelink Buffer Status Report (SL-BSR) MAC CE may be configured as one of the following:

[0197] - SL-BSR format (variable size); or

[0198] - Truncated SL-BSR format (variable size).

[0199] For example, the SL-BSR and truncated SL-BSR MAC control elements may include one destination index field, one LCG ID field, and one buffer size field for each reported target group.

[0200] For example, the SL-BSR format can be identified by a MAC subheader with an LCID.

[0201] For example, the fields of SL-BSR MAC CE can be defined as follows:

[0202] - Destination Index: The Destination Index field can identify a destination. This field can be 5 bits long. This value, if present, can be set to an index corresponding to an SL destination identifier associated with the same destination as reported in sl-TxResourceReqList, sl-TxResourceReqListDisc, sl-TxResourceReqListCommRelay, and sl-TxResourceReqListL2-U2U. This value can be indexed sequentially from 0 in the same ascending order of the SL destination identifiers within sl-TxResourceReqList, sl-TxResourceReqListDisc, sl-TxResourceReqListCommRelay, and sl-TxResourceReqListL2-U2U. If multiple lists are reported, this value can be indexed sequentially across all lists in the same order as presented in the SidelinkUEInformationNR message.

[0203] - LCG ID: The Logical Channel Group ID field can identify the group of logical channels(s) for which the SL buffer status is reported. This field can be 3 bits long.

[0204] - Buffer Size: The Buffer Size field may identify the total amount of data available for data capacity calculation procedures after the MAC PDU is constructed across all logical channels of the destination's logical channel group (for example, the value of the Buffer Size field may be 0 after the logical channel prioritization procedure). The amount of data may be expressed in bytes. The sizes of the RLC header and MAC subheader may not be considered when calculating the buffer size. The length of this field may be 8 bits. For the truncated SL-BSR format, the number of included Buffer Size fields may be maximized as long as it does not exceed the number of padding bits.

[0205] For example, the buffer sizes of LCGs may be indicated in order of priority of the sidelink logical channels that hold data to be transmitted in each LCG, regardless of the destination index field value.

[0206] In sidelink positioning between UEs, the sidelink positioning reference signal (SL-PRS) is not data coming from an upper layer, so it does not correspond to a previously defined logical channel, and the corresponding data size does not exist. Therefore, for SL-PRS resource allocation, it is impossible to use the SL-BSR MAC CE, which conveys the required data size for each logical channel group.

[0207] Therefore, a new MAC CE, SL-PRS resource request MAC CE, is introduced, and the MAC CE includes SL-PRS priority information and SL-PRS bandwidth information to be transmitted for each destination index.

[0208] SL-PRS priority can be determined / set based on positioning QoS. However, the specific determination method is not specified in the 3GPP standard. The UE can determine / calculate the SL-PRS priority and required bandwidth based on positioning QoS and notify the base station.

[0209] Using this information, the base station can allocate bandwidth to meet the performance requirements of the positioning service. It can also prioritize multiple resource requests.

[0210] FIG. 14 illustrates an example of an SL-PRS resource request MAC CE according to an embodiment of the present disclosure. The embodiment of FIG. 14 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.

[0211] Referring to Figure 14, for example, an SL-PRS resource request MAC CE may be identified by a MAC subheader with an eLCID. For example, the SL-PRS resource request MAC CE may include the following fields, which may be variable in size:

[0212] - Destination Index: The Destination Index field can identify a destination. This field can be 5 bits long. If present, this value can be set to an index corresponding to an SL destination identifier associated with the same destination reported in the sl-PosTxResourceReqList. This value can be indexed sequentially from 0 in the same ascending order of the SL destination identifiers in the sl-PosTxResourceReqList. If multiple lists are reported, this value can be indexed sequentially across all lists in the same order as presented in the SidelinkUEInformationNR message.

[0213] - SL-PRS Priority: The priority of the pending SL-PRS transmission. This field can be 3 bits long.

[0214] - SL-PRS Bandwidth: The minimum bandwidth required for a pending SL-PRS transmission. This field can be 5 bits long. The encoding of this field can be identical to sl-PRS-Bandwidth in IE SL-PRS-QoS-Info, and a code point value of 0 can correspond to the sl-PRS-Bandwidth field value "mhz5", a code point value of 1 can correspond to the sl-PRS-Bandwidth field value "mhz10", and so on.

[0215] - R: Reserved bit, can be set to 0.

[0216] Thus, in sidelink positioning, QoS for positioning reference signals, not data, and the SL-PRS MAC CE to satisfy this were introduced. However, SL-PRS priorities are for relative priority comparisons between UEs and / or services and do not reflect the actual required / targeted positioning QoS. Furthermore, bandwidth does not reflect the actual required / targeted positioning QoS in sidelink positioning.

[0217] Conventional positioning services determine whether the service's QoS requirements are met based on the final calculated location value. If the QoS requirements are not met, subsequent resource reallocation is performed. This has the limitation that remedial actions can only be taken after a QoS failure has occurred, resulting in increased delays until positioning is determined.

[0218] Furthermore, in sidelink positioning, the SL-PRS resource request MAC CE was introduced to request resources based on PRS signals rather than data. However, this MAC CE only reflects priorities based on QoS and does not actually reflect the quantitative difference between the target QoS and the current QoS. This makes it difficult for the base station to make appropriate resource allocation decisions, limiting sensing performance optimization.

[0219] In this way, the conventional technology lacks a mechanism for recognizing and controlling sensing or positioning QoS in real time, which makes it difficult to control resources efficiently and improve QoS satisfaction.

[0220] The present disclosure aims to address the limitations of conventional structures that make it difficult to achieve real-time quality of service (QoS) in wireless sensing (e.g., ISAC) services. Conventional positioning / sensing systems determine whether to allocate additional resources only after comparing the calculated results with the target QoS after the service is completed. Therefore, if the target criteria are not met, the same process must be repeated, resulting in accumulated delay and overhead. Furthermore, existing control messages, such as the SL-PRS resource request MAC CE, only convey “priority,” making it impossible to determine the quantitative difference between the target and current QoS. This makes it difficult for base stations (gNBs) / servers to immediately assess appropriate resources, resulting in over / under allocation of resources or a deterioration in QoS satisfaction. Furthermore, because the target QoS values ​​are not shared in real time between the sensing node (UE) and the resource management entity (gNB), it is difficult for both devices to assess the service status based on the same criteria at the same time.

[0221] In summary, the core task of this disclosure is to provide a mechanism that can simultaneously and numerically report target QoS values ​​and current measured QoS values, thereby realizing delay-free resource rebalancing and precise QoS-awareness.

[0222] In the present disclosure, for example, a QoS-awareness enhancement method and message structure for ensuring sensing QoS may be proposed. For example, a sensing node (e.g., UE) may directly transmit currently measured QoS information, including target QoS information (e.g., accuracy, reliability) corresponding to a sensing session, to a sensing resource allocation entity (e.g., gNB), thereby enabling resource control based on QoS-awareness.

[0223] The present disclosure may include the following specific configurations:

[0224] - Definition of a sensing QoS reporting message structure that includes detailed QoS parameters such as target accuracy, current accuracy, best / worst accuracy, etc.

[0225] - A method of conveying the QoS information (or delta information) through MAC CE or sensing protocol.

[0226] - A method of classifying and transmitting the number of detected objects based on the QoS threshold.

[0227] - A structure that simultaneously improves resource efficiency and QoS satisfaction by dynamically increasing or decreasing resources based on the difference between the target QoS and the current QoS on the receiving side.

[0228] In the present disclosure, a QoS-awareness enhancement method and message for sensing QoS assurance can be proposed.

[0229] For example, sensing QoS-awareness enhancements can be proposed.

[0230] FIG. 15 illustrates a sensing procedure according to an embodiment of the present disclosure. The embodiment of FIG. 15 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.

[0231] Referring to FIG. 15, for example, in step S1510, the first device can obtain information related to a target QoS value associated with a sensing service. For example, in step S1510, the third device can set information related to a target QoS value associated with a sensing service to the first device. For example, a representative index among the sensing performance / quality indices may be the accuracy of the detected target object. For example, this may indicate the accuracy of the detected object. For example, such sensing accuracy may be closely related to the resource allocation of the assigned sensing signal.

[0232] For example, especially in UE-based sensing (wherein, for example, the UE may be not only a normal UE but also a public / infrastructure UE such as a conventional RSU or PSU), the UE may be responsible for sensing analysis / processing. In this case, for example, regardless of the sensing mode (TRP mono-static, UE mono-static, TRP-TRP bi-static, UE-UE bi-static, TRP-UE bi-static, UE-TRP bi-static, etc.), the UE should be able to request resources to satisfy the quality required by the sensing service it wants to perform.

[0233] For this purpose, for example, the UE may transmit sensing session information, assuming that associated sensing services, here one sensing service is associated with one sensing session. For example, in step S1520, the first device may measure a QoS value associated with the sensing service. For example, in step S1530, the first device may report information related to a target QoS value and information related to a measured QoS value. For example, the quality (sensing accuracy) of the sensing service requested / targeted in the sensing session may be transmitted, and the currently measured quality may be transmitted. For example, direct QoS-awareness between the sensing node and the sensing resource allocation entity may be enabled by transmitting the target QoS value of a specific sensing service and the currently measured QoS value.

[0234] For example, although not shown in Fig. 15, if the sensing resource allocation entity is a base station, the received target QoS and the current QoS value can be compared, and if the current QoS is insufficient compared to the target QoS, more resources can be allocated. Or, for example, conversely, if the current QoS exceeds the target QoS, the allocated resources can be reduced to increase resource efficiency.

[0235] For example, in FIG. 15, the first device may be a terminal. For example, the first device may be a device, a portable device, a wireless device, etc. For example, the second device may be a base station. For example, the second device may be a radio access network (RAN) node, a non-terrestrial network (NTN) cell / node, a transmission reception point (TRP), a network, an integrated access and backhaul (IAB) node, a device, a portable device, a wireless device, etc. For example, the third device may be a server or a server terminal. For example, the third device may be an anchor or an anchor terminal. For example, the third device may be a location server. For example, the third device may be a location management function (LMF). For example, the first device and / or the second device may be a sensing entity. For example, the third device may be a sensing entity.

[0236] For example, by utilizing these direct QoS values, sensing QoS-awareness can be improved. This can, for example, address the issue of delays caused by the use of indirect parameters, and ultimately increase the probability of satisfying sensing QoS (e.g., the success rate of sensing service operation).

[0237] For example, a method for conveying target / current QoS information may be proposed.

[0238] For example, the currently measured sensing quality (sensing accuracy) may include at least one of the following:

[0239] - Average accuracy value of all detected target objects (current averaged accuracy)

[0240] - Worst accuracy value of all detected target objects

[0241] - Best accuracy value of all detected target objects

[0242] For example, in the above example, three accuracy values ​​can be distinguished. For example, all or some values ​​can be sent. For example, the values ​​to be sent can be set.

[0243] Additionally, signaling overhead can be reduced, for example, by transmitting a delta value between the target QoS value and the current QoS value.

[0244] Alternatively, for example, by sensing accuracy of the currently detected target object, the quality (sensing accuracy) may include at least one of the following:

[0245] - Number of target objects detected above target QoS

[0246] - Number of target objects detected below target QoS

[0247] In the example above, for example, the target QoS can be used as a single threshold value. Additionally, for example, a separate threshold value other than the target QoS can be set / received. For example, such a threshold value can have one or more multiple values. In this way, for example, when separate and / or multiple threshold values ​​are set, target objects can be distinguished and transmitted based on the threshold settings, and the number of objects can be calculated accordingly.

[0248] In this disclosure, accuracy may be used as an example of sensing QoS. This is merely an example; other QoS parameters, such as confidence level / value, may also be used. For example, even when using QoS parameters other than accuracy, the method proposed in this disclosure can be applied in the same or similar manner.

[0249] For example, a target / current QoS information delivery message may be proposed.

[0250] For example, the above QoS report message may utilize messages of various protocol layers, such as sensing protocol, RRC, or MAC signaling.

[0251] For example, when delivered via a sensing protocol (or RRC), a QoS structure / message may be utilized. For example, when delivered via a sensing protocol (or RRC), a SensingQoSReport may be utilized. For example, a SensingQoSReport may (optionally) include horizontalAccuracy. For example, a SensingQoSReport may (optionally) include verticalAccuracy.

[0252] For example, horizontalAccuracy may contain at least one of the following:

[0253] - Target Accuracy: This field can indicate the target accuracy (related to the sensing service).

[0254] - Current Accuracy: This field can indicate the current accuracy (related to the sensing service). For example, the current accuracy could be the (average) accuracy value for all detected objects.

[0255] - Worst Accuracy: This field can indicate the worst accuracy (related to the sensing service). For example, the worst accuracy could be the worst accuracy value for all detected objects.

[0256] - Best Accuracy: This field can indicate the best accuracy (related to the sensing service). For example, the best accuracy could be the best accuracy value for all detected objects.

[0257] For example, VerticalAccuracy may contain at least one of the following:

[0258] - Target Accuracy: This field can indicate the target accuracy (related to the sensing service). For example, the target accuracy can have a value between 0 and 127.

[0259] - Current Accuracy: This field can indicate the current accuracy (related to the sensing service). For example, the target accuracy could be the (average) accuracy value for all detected target objects. For example, the current accuracy could have a value between 0 and 127.

[0261] - Best Accuracy: This field can indicate the best accuracy (related to the sensing service). For example, the best accuracy could be the best accuracy value for all detected objects. For example, the best accuracy could have a value between 0 and 127.

[0262] - Target Confidence: This field can indicate the target confidence (related to the sensing service). For example, the target confidence can have a value between 0 and 100.

[0263] - Current Confidence: This field can indicate the current confidence level (related to the sensing service). For example, the current confidence level could be the (average) confidence level of all detected objects. For example, the current confidence level could have a value between 0 and 100.

[0264] - Worst Confidence: This field can indicate the worst confidence level (related to the sensing service). For example, the worst confidence level could be the worst confidence level for all detected objects. For example, the worst confidence level could have a value between 0 and 100.

[0265] - Best Confidence: This field can indicate the best confidence level (related to the sensing service). For example, the best confidence level could be the best confidence value for all detected objects. For example, the best confidence level could have a value between 0 and 100.

[0266] For example, when delivered via a sensing protocol (or RRC), a QoS structure / message as shown in Table 3 below may be utilized. Table 3 shows a Sensing QoS Report IE (information element) for delivering measured QoS information according to an embodiment of the present disclosure. The embodiment of Table 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.

[0290] The above methods proposed in this disclosure can be applied to both 3GPP sensing data and non-3GPP sensing data.

[0291] For example, in the present disclosure, the sensing data may be data derived by a sensing wireless measurement entity based on a wireless signal that is influenced (e.g., reflected, refracted, or diffracted) by an object or environment of interest for sensing purposes. For example, this data may be raw measurements and optionally be further processed within the sensing wireless measurement entity. For example, the sensing data may include at least one of 3GPP sensing data or non-3GPP sensing data.

[0292] For example, in the present disclosure, 3GPP sensing data is data obtained from 3GPP wireless signals that have been affected (e.g., reflected, refracted, diffracted) by an object or environment of interest for sensing purposes, and may optionally be processed within a 5G system.

[0293] For example, in the present disclosure, non-3GPP sensing data may be data provided by a non-3GPP sensor (e.g., video, LiDAR, sonar) about an object or environment of interest for sensing purposes.

[0294] For example, in the present disclosure, 5G / 6G wireless sensing may be a 5GS / 6GS capability that provides the ability to acquire information about characteristics of an environment and / or objects within the environment (e.g., shape, size, orientation, speed, position, distance, relative motion between objects, etc.) using NR radio frequency signals, and in some cases may be extended by information generated through capabilities previously defined in the EPC and / or E-UTRAN.

[0295] For example, in the present disclosure, sensing assistance information may be provided to the 5G system from a trusted third party and may be used to support the derivation of sensing results. This information may not include 3GPP sensing data. Examples of sensing assistance information may include map information, area information, a UE identifier (ID) attached to or located near a sensing target, UE location information, UE speed information, and the like.

[0296] For example, in the present disclosure, sensing context information may be information that a 5G / 6G system exposes to a trusted third party along with sensing results, providing context regarding the conditions under which the sensing results were derived. This information may not include 3GPP sensing data. For example, examples of sensing context information may include map information, area information, capture time, UE location, and ID. This context information may be required in scenarios where sensing results must be combined with data from other sources outside of 5GS.

[0297] For example, in the present disclosure, a sensing group may be a set of sensing transmitters and sensing receivers whose locations are known and capable of synchronously collecting sensing data.

[0298] For example, in the present disclosure, a sensing receiver may be an entity that receives sensing signals used by a sensing service in its operation. The sensing receiver may be part of a RAN node or a UE. The sensing receiver may be located in the same entity as the sensing transmitter or in a different entity.

[0299] For example, in the present disclosure, the sensing result may be processed 3GPP sensing data requested by a service consumer.

[0300] For example, in the present disclosure, a sensing signal may be a transmission signal on a 3GPP radio interface that can be used for sensing purposes. For example, this definition may refer to a NR radio frequency signal, and in some cases, may be extended to information generated from existing functions of the EPC and / or E-UTRAN.

[0301] For example, a sensing transmitter may be an entity that transmits sensing signals used by a sensing service in its operation. The sensing transmitter may be part of a RAN node or a UE. The sensing transmitter may be located in the same entity as the sensing receiver or in a different entity.

[0302] For example, a target sensing service area may be a location area in Cartesian coordinates that satisfies a specific sensing service quality and that is to sense the environment and / or object characteristics within the environment derived from (e.g., reflected, refracted, diffracted) 3GPP radio signals. This may include both indoor and outdoor environments.

[0303] For example, the present disclosure may be applied to a base station (e.g., a TRP) and / or a terminal monostatic. For example, the present disclosure may also be applied to a base station-base station (e.g., a TRP-TRP), a base station-UE (e.g., a TRP-UE), a UE-base station (e.g., a UE-TRP), and / or a UE-UE bistatic.

[0305] For example, whether the proposed rule of the present disclosure applies and / or the related parameter setting values ​​can be specifically (or differently or independently) set depending on whether PUCCH configuration is supported (e.g., when PUCCH resources are configured or when PUCCH resources are not configured). For example, whether the proposed rule of the present disclosure applies and / or the related parameter setting values ​​can be specifically (or differently or independently) set for a resource pool (e.g., a resource pool where PSFCH is configured or a resource pool where PSFCH is not configured).

For example, the instructions, based on execution by the at least one processor, may cause a second device to: receive, from a first device, information related to a target quality of service (QoS) value associated with a sensing service and information related to a measured QoS value associated with the sensing service; and transmit a sensing resource to the first device based on receipt of the information related to the target QoS value associated with the sensing service and the information related to the measured QoS value associated with the sensing service.

[0404] For example, by utilizing these direct QoS values, sensing QoS-awareness can be improved. This can, for example, address the issue of delays caused by the use of indirect parameters, and ultimately increase the probability of satisfying sensing QoS (e.g., the success rate of sensing service operation).

[0405] This disclosure enables real-time recognition of the QoS of sensing services, enabling more appropriate and agile resource control. Therefore, by quantitatively assessing whether the target QoS is insufficient or exceeded, resource overuse and waste can be reduced. Compared to existing indirect indicator-based resource request methods, this accuracy-based, direct information delivery structure can simultaneously improve the success rate and time efficiency of sensing services.

[0406] The present disclosure comprises the steps of (i) acquiring target QoS information, (ii) measuring current QoS, and (iii) reporting including the two values, thereby achieving the following effects.

[0407] First, the base station or sensing server can immediately compare the target and current QoS values, so that when the target is expected to be missed, additional resources can be immediately allocated without service interruption, or conversely, resources can be recovered when the target is exceeded, thereby significantly reducing delays caused by service retries.

[0408] Second, by optionally including a delta value representing the difference between two values ​​or the number of objects above / below the target in the report message, control plane signaling can be minimized while preserving quantitative gap information, allowing the base station to increase or decrease resources based on scientific evidence.

[0409] Third, real-time QoS awareness is achieved by sensing nodes and resource management entities sharing the same target value at the same time, thereby improving both sensing success rate and resource efficiency.

[0410] Fourth, in addition to accuracy, other QoS parameters such as confidence / integrity can also be transmitted through the same framework, allowing for universal expansion to various sensing scenarios in 5G as well as 6G ISAC environments.

[0411] Ultimately, the present disclosure provides technical and economic benefits of (a) increasing the success rate of sensing services, (b) minimizing service delay, and (c) maximizing network resource efficiency by implementing “real-time QoS-awareness-based resource control.”

[0412] The various embodiments of the present disclosure may be combined with each other, and some descriptions, functions, procedures, proposals, methods and / or operations of the various embodiments may be omitted.

[0430] FIG. 23 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 23 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.

[0431] Referring to FIG. 23, 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 operations / functions of FIG. 23 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 22. The hardware elements of FIG. 23 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 22. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 22. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 22, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 22.

[0432] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 23. Here, the codeword is an encoded bit sequence of an information block. The information block can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).

[0433] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010). The scramble sequence used for scrambling is generated based on an initialization value, and the initialization value may include ID information of the 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 a precoding matrix W of N*M. 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 complex modulation symbols. In addition, the precoder (1040) can perform precoding without performing transform precoding.

[0434] The resource mapper (1050) can map modulation symbols of each antenna port to time-frequency resources. The time-frequency resources can include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. The signal generator (1060) generates a wireless signal from the mapped modulation symbols, and the generated wireless signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) can include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0435] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 23. For example, a wireless device (e.g., 100, 200 of FIG. 22) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks 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.
