[0038] 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.

[0039] 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).

[0040] 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.

[0041] 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 may be transmitted and received as a single message (e.g., MsgA), and / or Msg2 and Msg4 may be transmitted and received as a single message (e.g., MsgB).

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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).

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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).

[0053] 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.

[0054] 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).

[0055] 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).

[0056] 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.

[0057] 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

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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, large-scale 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.

[0069] - 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.

[0070] - 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.

[0084] - 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).

[0085] - 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).

[0086] - 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.

[0087] - 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.

[0088] - 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.

[0090] 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.

[0091] For example, a terminal can obtain information about the characteristics of the environment and / or 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 capabilities do not require connecting to an object via a device within the network, they can provide services for object location determination without a device. 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, object recognition (e.g., vehicles, humans, animals, UAVs), and high-precision localization, tracking, and activity recognition. Radio 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, radio 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. Therefore, wireless sensing can provide an opportunity to enhance existing communication systems from communication networks into wireless communication and sensing networks.

[0092] 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, suggestions, methods, and / or operations of the embodiments 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).

[0093] Referring to FIG. 8, a sensing transmitter may transmit a sensing signal for sensing one or more objects (and / or the environment surrounding the objects). For example, the sensing signal may be a radio (frequency) signal defined to be transmittable by a base station / terminal. For example, a sensing receiver may receive a signal that is scattered or reflected by one or more objects (and / or the environment surrounding the objects) from the sensing signal transmitted by the sensing transmitter. For example, at the sensing receiver, sensing data may be derived from the scattered or reflected signal, and a sensing result may be generated or obtained through processing of the sensing data. Here, for example, the sensing result may include characteristic information (e.g., location, distance, speed, angle, etc.) about one or more objects (and / or the environment surrounding the objects). For example, the sensing results generated / acquired in this way may be utilized for wireless sensing services (e.g., detection, tracking of objects and / or environments, etc.) or provided / disclosed to a trusted third party.

[0094] For example, a sensing transmitter may be a base station or terminal that transmits a sensing signal to be used for the operation of a sensing service, and the sensing transmitter may be located at the same base station or terminal as the sensing receiver or at a different base station or terminal. For example, a sensing receiver may be a base station or terminal that receives a sensing signal to be used for the operation of a sensing service, and the sensing receiver may be located at the same base station or terminal as the sensing transmitter or at a different base station or terminal. For example, a sensing target may be an object to be detected by deriving the characteristics of an object within the environment from the 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 that of a sensing target. For example, monostatic sensing may be a sensing in which the sensing transmitter and the sensing receiver coexist at the same base station or terminal. For example, bistatic sensing may be sensing where the sensing transmitter and the sensing receiver are located at different base stations or terminals. For example, multistatic sensing may be sensing where 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 below 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 above or equal to a threshold, it may be defined as bistatic sensing or multistatic sensing.For example, the terminal can transmit a sensing signal over a wireless interface that can be used for sensing purposes. For example, the terminal can transmit a sensing signal over a 3GPP wireless interface that can be used for sensing purposes.

[0095] For example, the common framework of the ISAC channel model can be composed of components of the target channel and components of the background channel. For example, this can be obtained based on Equation 1.

[0096]

[0097] Here, for example, target channel H target It may include all [multipath] components affected by the sensing target. For example, background channel H Background It may include other [multipath] components that do not belong to the target channel.

[0098] For example, radar cross-section (RCS) may be a measure of how well a radar sensor can detect a target. Therefore, it can often be referred to as an electromagnetic characteristic of the target. For example, a larger RCS may indicate that the target can be detected more easily. For example, in radar sensor measurements, power may be transmitted toward the target, and the target may reflect some of the power back to the receiver. For example, received power may be based on the target's RCS, among other factors. For example, received power may be proportional to the RCS. For example, the target's RCS 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.

[0099] FIG. 9 illustrates the relationship between RCS, distance (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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0100] Referring to Fig. 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 equation can be defined as Equation 2.

[0101]

[0102] Here, for example, P TX can be transmitter power [W], and G TXε₀ can be the gain of the transmitting antenna [dimensionless], D can be the distance between the EUT (equipment under test) and the target [m], and RCS is the radar cross-section [m² 2 ] could be, and P RX can be the power [W] that the EUTT receives back from the object, and A eff is the effective area of ​​the receiving antenna [m 2 ] can be. For example, A eff It can be obtained based on mathematical formula 3.

[0103]

[0104] Here, for example, G RX λ 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].

[0105] For example, if a transmitter and a receiver are placed together and the same antenna is used for transmission and reception (G TX = G RX = G), the related radar mathematical formula can be defined as Equation 4.

[0106]

[0107] Here, for example, P TX ε₀ can be transmitter power [W], G can be the gain of the transmitting antenna [dimensionless], D can be the distance between the EUT (equipment under test) and the target [m], and RCS is the radar cross-section [m² 2 ] could be, and P RX ≠ Power [W] received back from the object by the EUT.

[0108] Meanwhile, in recognizing the movement or gesture of an object to be sensed, it is not possible to determine this through conventional information such as the distance to the object, the object's speed of movement, and the object's orientation. Instead, micro-Doppler frequency values ​​generated, for example, by the rotation of a UAV's wings, the movement of a walking person's arms and legs, or the flapping of a bird's wings, can be estimated, and based on the pattern of the estimated micro-Doppler frequency, the object or the object's movement / gesture can be recognized.

[0125] FIG. 10 illustrates a procedure for reporting sensing results 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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0126] To estimate the micro-Doppler frequency described above, a method may be used, for example, to estimate time-varying Doppler frequency values ​​based on a Time-Velocity Diagram (TVD) obtained by performing a Short-Time Fourier Transform (STFT) based on a received sensing signal, and / or, for example, to calculate a Cadence-Velocity Diagram (CVD) that estimates the frequency of occurrence of specific Doppler frequency values ​​by applying a Fast Fourier Transform (FFT) along the time axis based on the TVD (e.g., the time axis on the TVD is transformed into a cadence frequency axis), and / or, for example, to estimate the time interval of periodic Doppler frequency values ​​generated by periodically repeating movements by obtaining an Inverse Fast Fourier Transform (IFFT) value obtained by taking the logarithm of the result of the STFT. For example, the TVD may be obtained by performing an STFT based on a received sensing signal, and the TVD may visualize and represent changes in Doppler frequency values ​​and / or velocity values ​​along the time axis. Therefore, time-varying Doppler frequency values ​​can be estimated. For example, CVD can be obtained or calculated by applying an FFT to the time axis based on TVD. Here, for example, CVD can be used to estimate the frequency at which specific Doppler frequency values ​​occur or the periodicity of the movement. Here, for example, the time axis on the TVD can be transformed and represented as a cadence frequency axis.

[0127] For example, in order to report a sensing result through the micro-Doppler frequency estimation described above, the sensing transmitter and / or sensing receiver and / or SMF performing the sensing may perform the following operations. In an embodiment of the present disclosure, the first device may refer to the sensing receiver and / or sensing transmitter, and the second device may refer to the sensing transmitter and / or SMF. For example, in step S1010, setting information related to the micro-Doppler measurement (e.g., parameters associated with STFT) may be set for the first device and / or the second device. For example, in step S1020, the first device may obtain a sensing result for the sensing signal based on the setting information related to the micro-Doppler measurement (e.g., parameters associated with STFT). For example, in step S1030, the first device may report the sensing result to the second device.

[0128] For example, the sensing receiver can report a sensing result associated with the Time-Velocity Diagram (TVD) result obtained through the above STFT.

[0129] For example, parameters associated with an STFT to be performed based on a received sensing signal (e.g., as described below) may be set (in advance) (in a resource pool), or may be set in a sensing transmitter and / or a sensing receiver, or said parameters may be requested by a sensing transmitter and / or a sensing receiver. For example, parameters associated with an STFT (e.g., configuration information related to micro-Doppler measurements) may include at least one of an STFT block length, an interval length between STFT blocks (or an STFT block period), and / or an overlapping ratio between STFT blocks.

[0130] For example, the SMF can instruct / transmit information about the above parameters to the sensing transmitter and / or sensing receiver (e.g., to include it in the sensing result report value for the sensing signal).

[0131] For example, the sensing transmitter can transmit information about the parameter to the sensing receiver through a (control) channel associated with the sensing signal to be transmitted.

[0132] For example, the sensing receiver may transmit the parameter information to the SMF and / or the sensing transmitter in connection with a request to transmit a sensing signal that it wishes to receive.

[0133] For example, a sensing receiver may obtain a micro-Doppler frequency estimation-based sensing result based on a received sensing signal, and / or the sensing receiver may request the SMF and / or the sensing transmitter to change the parameter(s) in conjunction with a sensing signal to be requested from the sensing transmitter based on the sensing result. For example, if the micro-Doppler frequency estimation-based sensing result does not satisfy the required sensing QoS, the sensing receiver may transmit the parameter information associated with an additionally transmitted sensing signal to the SMF and / or the sensing transmitter to satisfy the required sensing QoS.

[0134] For example, when a sensing receiver reports a sensing result associated with a micro-Doppler frequency for a received sensing signal, it may include parameter information associated with the processing of the received sensing signal in the reported value.

[0135] For example, the SMF may request the sensing transmitter and / or sensing receiver to use the parameter(s) in conjunction with the sensing signal based on the sensing results reported from the sensing receiver. For example, if the sensing results reported from the sensing receiver do not satisfy the required sensing QoS, the SMF may transmit the parameter information associated with the additionally transmitted sensing signal to the sensing transmitter and / or sensing receiver to satisfy the required sensing QoS. For example, to obtain micro-Doppler frequency estimation results with high frequency resolution in conjunction with micro-Doppler frequency estimation, the STFT block length may be set to a relatively long length. For example, to obtain micro-Doppler frequency estimation results with high time resolution in conjunction with micro-Doppler frequency estimation (e.g., to obtain micro-Doppler frequency estimation results that vary within a shorter time), the STFT block length may be set to a short length, and / or the interval length between the STFT blocks may be changed to a short length.

[0136] For example, the sensing receiver may report information regarding the TVD results to the SMF. For example, the entire TVD results may be reported to the SMF by the STFT block index. For example, TVD result values ​​above a threshold set (previously by the SMF) by time (or STFT block index), and / or TVD result values ​​within the threshold interval, and / or micro-Doppler frequency values ​​associated with the TVD result values ​​may be reported. For example, the range or minimum / maximum values ​​of the micro-Doppler frequency values ​​by time (or STFT block index) may be reported. For example, micro-Doppler frequency values ​​associated with up to M TVD result values ​​(within the threshold interval) by time (or STFT block index) may be reported. For example, only the differential values ​​of the values ​​associated with the above reports by STFT block index k may be reported (e.g., the difference between STFT block index k and index k-1 is reported). For example, at least one of the following estimated parameter values ​​extracted based on the above TVD results may be reported to be used for micro-Doppler frequency-based object estimation.

[0137] - Bandwidth of the entire Doppler frequency spectrum including micro-Doppler frequency values ​​estimated based on the above TVD results

[0138] - Bandwidth of the entire Doppler frequency spectrum excluding micro-Doppler frequency values, estimated based on the above TVD results

[0139] - A period or time interval in which an arbitrary micro-Doppler frequency value is repeated, estimated based on the above TVD results.

[0140] - Standard deviation / variance of Doppler frequency values ​​estimated based on the above TVD results

[0141] For example, the sensing receiver may estimate the Cadence-Velocity Diagram (CVD) and report associated sensing results. For example, the sensing receiver may report the M largest CVD result values. For example, the M largest CVD result values ​​may be the top M CVD result values ​​from the largest CVD result value. For example, cadence frequency values ​​associated with the M CVD result values ​​may be reported. For example, a velocity profile associated with the cadence frequency values ​​(e.g., a velocity diagram having / corresponding to the cadence frequency) may be reported to the SMF. For example, the M values ​​may be set (in advance) to the sensing transmitter and / or sensing receiver (by the SMF). For example, the above operation may be additionally performed in conjunction with the STFT result when the sensing receiver reports the STFT result.

[0142] For example, the sensing receiver may estimate the time interval of the periodic Doppler frequency values ​​and report the associated sensing results. For example, the sensing receiver may report the M largest result values ​​for the IFFT values ​​corresponding to the log value of the STFT. For example, the M largest result values ​​may be the top M result values ​​from the largest result value. For example, the time interval values ​​of the periodic Doppler frequency values ​​associated with the M result values ​​may be reported to the SMF. For example, the above operation may be additionally performed in conjunction with the STFT result when the sensing receiver reports the STFT result.

[0146] FIG. 11 illustrates a method performed by a first device according to one embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0147] Referring to FIG. 11, in step S1110, the first device can obtain setting information related to micro-Doppler measurement. In step S1120, the first device can obtain a sensing result for a sensing signal based on the setting information related to micro-Doppler measurement. In step S1130, the first device can report the sensing result to the second device.

[0149] For example, the sensing result may include information related to the Time-Velocity Diagram (TVD) result obtained by performing STFT based on the configuration information related to the micro-Doppler measurement. For example, the information related to the TVD result may include TVD result values ​​for each STFT block index.

[0150] For example, setting information related to the micro-Doppler measurement can be obtained based on a channel or control channel related to the sensing signal.

[0151] Additionally, for example, the first device may transmit a request to the second device for a change in configuration information related to the micro-Doppler measurement based on the sensing result and the sensing QoS (Quality of Service). For example, the request may include at least one of information related to additional sensing signals, information related to the STFT block length, information related to the interval length between STFT blocks, information related to the STFT block period, or information related to the overlap ratio between STFT blocks.

[0152] For example, the sensing result may include at least one of information related to the STFT block length, information related to the interval length between STFT blocks, information related to the STFT block period, or information related to the overlap ratio between STFT blocks, which were used to obtain the sensing result.

[0195] FIG. 15 shows a signal processing circuit for a transmission signal according to one embodiment of the present disclosure. The embodiment of FIG. 15 can be combined with various embodiments of the present disclosure.

[0196] Referring to FIG. 15, 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. 15 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 14. The hardware elements of FIG. 15 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 14. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 14. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 14, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 14.

[0197] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 15. 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).

[0198] 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.

[0199] 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.

[0200] 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. 15. For example, a wireless device (e.g., 100, 200 in FIG. 14) 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.
