[0037] 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.

[0038] 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).

[0039] 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.

[0040] In step S105, the first device and the second device may perform a random access procedure. For example, the first device may transmit and / or receive at least one message for the random access procedure (e.g., random access preamble, random access response message, etc.) based on information related to the random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device may transmit a preamble (e.g., Msg1) through the random access channel, and the first device may receive a random access response message (e.g., Msg2). The first device may transmit a message (e.g., Msg3) containing information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device may receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be transmitted and received as a single message (e.g., MsgA), and / or Msg2 and Msg4 can be transmitted and received as a single message (e.g., MsgB).

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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).

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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).

[0052] 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.

[0053] 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).

[0054] 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).

[0055] 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.

[0056] 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

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] As core implementation technologies for 6G systems, technologies such as artificial intelligence (AI), THz (Terahertz) communication, optical wireless technology, free space optical transmission (FSO) backhaul networks, massive MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0068] - 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.

[0069] - 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] - 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).

[0085] - 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.

[0086] - Integrated Sensing and Communication (ISAC)

[0087] - 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.

[0088] 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.

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.

[0090] Below, the integrated sensing and communication (ISAC) mentioned above will be explained in detail.

[0091] Integrated Sensing and Communication (ISAC) refers to wireless sensing, a technology that utilizes radio frequencies to determine the instantaneous linear velocity, angle, and distance (range) of objects, thereby obtaining information about the characteristics of the environment and / or objects within that environment. Since radio frequency sensing capabilities do not require connecting to objects via devices within a network, they can provide services for object location determination without the need for devices. The ability to obtain range, velocity, and angle information from radio frequency signals can provide a wide range of new functions, such as various object detection and recognition (e.g., vehicles, humans, animals, UAVs), as well as high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to various industries (e.g., unmanned aerial vehicles, smart homes, V2X, factories, railways, public safety, etc.) that enable applications such as intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, and health and traffic management. In some cases, wireless sensing may utilize non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP-based sensing. For example, the operation of a wireless sensing service (e.g., sensing operation) may depend on the transmission, reflection, and scattering processing of wireless sensing signals. Thus, wireless sensing can provide an opportunity to enhance existing communication systems from communication networks to wireless communication and sensing networks. FIG. 8 illustrates an example of a sensing operation according to an embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of said embodiment may be omitted. Specifically, FIG. 8(a) illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and FIG. 8(b) illustrates an example of sensing using a separated sensing receiver and a sensing transmitter (e.g., bistatic sensing).

[0114] Meanwhile, resources for conventional radio link monitoring can be performed by measuring and reporting reference signals at the cell and / or beam level. However, for example, in the case of sensing, when monitoring reference signals at the cell or beam level, performance regarding background channels caused by the surrounding environment, rather than the target channel intended for sensing, may also be measured in combination. Furthermore, for example, in the case of sensing, performance regarding paths reflected by specific objects and areas may be of the utmost importance. Consequently, for the monitoring of a sensing link, it is necessary to measure and report performance regarding specific paths.

[0115] In summary, conventional sensing methods have limitations in that it is difficult to selectively observe the characteristics of paths associated with a specific target or sensing area, as various reflection paths in the time, space, and frequency domains are combined and processed without being distinguished from one another. Consequently, the reliability and accuracy of sensing results may be degraded due to the inclusion of reflection components formed by background environments or other objects unrelated to the target; furthermore, detection performance may be degraded as it is difficult to perform intensive sensing only in the area where the target is expected to be located.

[0116] In the present disclosure, a method for performing sensing of a target section and an apparatus supporting the same are proposed as follows.

[0117] For example, for the above operation, the SF (sensing function) and / or gNB may set a target path together when setting resources for link monitoring, and the receiver may measure and report reception performance for the path received within the set interval.

[0118] [Example #1] For example, the SF and / or gNB can set the target reception delay interval for measurement as follows, based on the relative position information of the target object and / or sensing area and the receiver.

[0119] For example, the receiving terminal may measure the received signal power (e.g., Reference Signals Received Path Power (RSRPP) or Reference Signal Strength Indicator (RSSI) per path, etc.) for path(s) received within a set reception time interval, and may report the measured received signal power value(s) along with information on the received signal resources to the SF and / or gNB. For example, the time interval may be a specific interval within the symbol interval based on the reception time of the sensing signal for monitoring, a specific time interval within the cyclic prefix (CP) interval of the sensing signal, or a specific time interval based on the Line of Sight (LoS) path, and this may be set in the form of an offset from the reference time and a duration. For example, the SF and / or gNB may have a sampling resolution on the time axis (e.g., a basic time unit) or ), or fixed time unit ( )) and number of samples( A specific target time interval may be indicated in the form of a product of ). For example, the time interval may be in the form of a set of time instant values ​​and / or time(s) of a specific delay path. For example, it may be in the form of a set of paths up to the M-th path within a specific time interval, M paths having received signal power above a preset threshold, or a set of paths indexed sequentially (e.g., ascending / descending). For example, it may be reported in the form of the received signal power of a reference path within the time interval (e.g., RSRPP with maximum received power) and the difference value thereof, or an average value for the entire path may be reported.

[0120] [Example #2] For example, the SF and / or gNB may set the target reception angle interval for measurement as follows, based on the relative position information of the target object and / or sensing area and the receiver.

[0121] For example, the receiving terminal may measure the received signal power (e.g., RSRPP or path-specific RSSI, etc.) for path(s) received within a set receiving angle interval and may report the measured received signal power value(s) along with information on the received signal resources to the SF and / or gNB. For example, the angle interval may be a specific interval within the receiving angle based on the receiving angle of a sensing signal for monitoring, or a specific angle interval based on the LoS path, and may be set in the form of an offset from the reference receiving angle and a duration interval (e.g., angle's width) for the azimuth and / or elevation angles. For example, the SF and / or gNB may have a resolution on the angle axis (e.g., fixed angular unit) )) and number of samples( A specific target time interval may be indicated in the form of a product of ). For example, the angle interval may be in the form of an instant value of a specific reception angle and / or a set of reception angle(s). For example, it may be in the form of a set of up to the M-th (M-th) path within a specific time interval, M paths having reception signal power above a preset threshold, or a set of paths indexed sequentially (e.g., ascending / descending). For example, it may be reported in the form of the reception signal power of a reference path (e.g., RSRPP with maximum reception power) and the difference value thereof, or an average value for the entire path may be reported.

[0122] [Example #3] For example, the SF and / or gNB can set the target reception frequency interval for measurement as follows, based on the relative position information of the target object and / or sensing area and the receiver.

[0123] For example, the receiving terminal may measure the received signal power (e.g., RSRPP or path-specific RSSI, etc.) for the received path(s) within a set frequency interval and may report the measured received signal power value(s) along with information on the received signal resources to the SF and / or gNB. For example, the frequency interval may be an offset range of the received frequency (e.g., frequency offset) relative to the center frequency of the sensing signal for monitoring, and may be set in the form of an offset from the reference frequency and a duration interval (e.g., frequency range). For example, the SF and / or gNB may have a resolution in the frequency axis (e.g., fixed frequency offset unit) )) and number of samples( A specific target time interval can be indicated in the form of a product of ). For example, the frequency interval may be in the form of a specific offset value and / or a set of offset value(s). For example, among paths having a specific frequency offset, it may be in the form of M paths having received signal power above a preset threshold, or a set of paths indexed sequentially (e.g., ascending / descending). Alternatively, for example, the frequency interval may be expressed as interval information associated with Doppler, and may be in the form of M points having power above a preset threshold among points having a specific Doppler component, or a set of points indexed sequentially (e.g., ascending / descending). For example, it may be reported in the form of the received signal power of a reference path (e.g., RSRPP with maximum received power) and the difference value thereof, or an average value for the entire path may be reported.

[0124] For example, measurements of a signal may be indicated in a combined form of time, angle, and frequency items. For example, measurements and reports regarding the receiving path may be performed within a specific time interval and at a specific reception angle (Example #1 + Example #2). For example, measurements and reports regarding the receiving path may be performed within a specific time interval and at a specific frequency (Example #1 + Example #3). For example, measurements and reports regarding the receiving path may be performed within a specific reception angle interval and at a specific frequency (Example #2 + Example #3). For example, measurements and reports regarding the receiving path may be performed within a specific time interval, at a specific reception angle, and at a specific frequency (Example #1 + Example #2 + Example #3).

[0125] For example, the SF and / or gNB may not restrict target paths for sensing link monitoring, and the receiving terminal may report to the SF and / or gNB about all paths received through a set signal, and / or paths having received signal power above a preset threshold. For example, it may be reported in the form of the received signal power of a reference path (e.g., RSRPP with maximum received power) and the difference value therefrom, or an average value for the entire path may be reported.

[0126] For example, in the operation described above, to obtain a measurement value for a target object, the receiver may obtain a receiveable (or decomposed) delay time, Doppler, and angle through signal processing, and a specific path corresponding to each value in the corresponding delay time-Doppler-angle domain may represent a single point on a 3D data cube. For example, the target segment information in the operation described above may be any segment information on the delay time / angle / Doppler data cube, or may be extended to target segment information for position information estimable from delay time and angle and / or velocity information estimable from Doppler.

[0127] For example, for the above-described operation, the receiver can report the sensing results in conjunction with the received paths during the sensing operation, and can perform the operation of filtering and measuring the sensing signal for monitoring the sensing link based on the set value.

[0128] For example, in the above-described reporting operation, the validity of the target interval (e.g., target interval for delay time, frequency offset, and reception angle) may be distorted due to the mobility of the receiver, and in this case, for example, the transceiver may perform the following operation.

[0129] For example, the SF and / or gNB can set an extended target interval that takes into account the mobility of the transmitter, receiver, and target. For example, a specific target interval on the time axis that takes into account the mobility of the receiver ( Guard time () at ) A target interval may be set and / or indicated, including ). For example, a specific target interval on the time axis considering the receiver's mobility ( The time () Target intervals may be set and / or indicated, including ). For example, for the operation described above, the receiver may report its mobility information to the SF and / or gNB in ​​advance, which may be information regarding the presence or absence of mobility and / or the magnitude of absolute mobility (e.g., absolute / relative velocity).

[0130] For example, the SF and / or gNB may pre-set a threshold for sensing results to validate the indicated target interval and notify the receiver. For example, a threshold associated with the receiver's mobility may be set. For example, if the receiver has mobility above a pre-set threshold, it may omit reporting the monitoring results. In this case, for example, it may report that the measurement value for the target interval is invalid due to the receiver's mobility. For example, if the receiver has mobility below the threshold, it may report the measurement value(s) in the target interval along with the presence or absence of mobility. For example, the receiver may determine validity itself and report the measurement value(s) in the target interval that have been pre-compensated for its mobility along with the presence or absence of mobility and / or compensation. Alternatively, for example, a threshold associated with the measurement result of the sensing signal may be set. For example, due to the receiver's mobility, the sensing result in terms of time, frequency, and angle (e.g., delay time ( ), frequency offset( ), reception angle( / Amount of change in )) (e.g., amount of change in latency for the same path ( ), change in reception angle( / ), frequency change amount( If )) is above a preset threshold, reporting for the target interval may be omitted. In this case, for example, it may be reported that the measurement value for the target interval is invalid due to the receiver's mobility. For example, if the receiver has mobility below the threshold, the measurement value(s) in the target interval or a preset target interval may be reported along with the presence or absence of mobility and / or compensation.

[0131] For example, the receiver can trigger a new target range setting by determining that the set target range is invalid and reporting values ​​associated with its mobility along with it.

[0132] For example, for the above-described operation, the receiver can determine its mobility through GNSS, positioning, and / or IMU (Inertial Measurement Unit) sensors, and accordingly, can continue adjustment operations for the target section and monitoring operations for the target path reflected and incident from the target object and / or target area.

[0133] For example, through the operation described above, monitoring of the sensing link can be performed, and the network can determine whether the sensing link has failed based on the measured and / or reported values. Additionally, for example, resources for the measurement value(s) can be configured for candidate transceivers to perform switching and recovery operations of the transceivers through comparison with the existing link.

[0134] FIG. 9 illustrates a method for performing sensing within a target interval set based on a target sensing area 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.

[0135] Referring to FIG. 9, a base station or a sensing function (SF) can set a target sensing area based on a moving target A. For example, the base station or SF can set a target sensing area where target A is expected to exist based on the location and mobility of target A. In this case, for example, the location information, direction of movement information, and speed information of target A can be obtained from previous sensing results or a network.

[0136] For example, a base station or SF may generate configuration information related to the target sensing area to be transmitted to a receiver (e.g., a sensing receiver). For example, the configuration information may include a target interval defined in the time, space, and / or frequency domains so that the receiver performs intensive sensing on the sensing signal related to the target sensing area.

[0137] For example, a base station or SF may set a reception delay interval based on the timing of reception of a sensing signal when a target sensing area is expected to exist within a certain distance range from a receiver. For example, the receiver may use the reception delay interval to process only the components of the sensing signal received within that interval and estimate the distance or range corresponding to the target sensing area based on the delay characteristics. Therefore, for example, the receiver may perform sensing only for the distance or range where the target sensing area is expected to exist, rather than for the entire distance range.

[0138] In addition, for example, a base station or SF may set a reception angle interval based on the reception angle of a sensing signal when a target sensing area is expected to be located in a certain direction relative to the receiver. For example, by selectively analyzing only the components of the sensing signal received within the reception angle interval, the receiver may limit reflections or clutter other than the direction in which the target sensing area is expected to be located, and perform spatially limited sensing on the target sensing area.

[0139] In addition, for example, a base station or SF may set a target reception frequency range in which a sensing signal related to the target sensing area is expected to be received based on mobility information of the target sensing area. For example, by analyzing only the components of the sensing signal received in the reception frequency range, the receiver may exclude reflections from stationary objects or moving objects unrelated to the target sensing area and improve the detection and estimation accuracy of the target sensing area.

[0140] Meanwhile, for example, due to the mobility of the receiver (or target sensing area), the target interval set by the aforementioned base station or SF may no longer be valid over time. In this case, for example, the base station or SF may include a guard interval in the target interval based on the mobility of the receiver (or target sensing area). For example, a reception delay interval, a reception angle interval, and / or a frequency interval set based on the time of reception of the sensing signal may be extended to include a margin (e.g., guard time, guard angle, or guard frequency) based on expected positional changes or velocity. As a result, even if, for example, the relative position or relative velocity of the receiver and the target sensing area changes, the sensing signal associated with the target sensing area may be maintained within the extended target interval.

[0141] Additionally, for example, if the receiver's mobility (e.g., absolute speed or relative speed) is above a threshold, the receiver may determine that the target interval set by the base station or SF no longer accurately includes the target sensing area. In this case, for example, the receiver may omit reporting the sensing results obtained in the target interval. Or, for example, the receiver may report that the sensing results obtained in the target interval are invalid. Or, for example, the receiver may trigger the base station or SF to reset (or update) the target interval.

[0142] Additionally, for example, if the amount of change in the sensing result acquired by the receiver in the target interval (e.g., the amount of change in the sensing result compared to the previous sensing result) is greater than a threshold, the receiver may determine that the target interval set by the base station or SF no longer accurately includes the target sensing area. In this case, for example, the receiver may omit reporting the sensing result acquired in the target interval. Or, for example, the receiver may report that the sensing result acquired in the target interval is invalid. Or, for example, the receiver may trigger the base station or SF to reset (or update) the target interval.

[0143] FIG. 10 illustrates a method in which a first device performs wireless communication 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 said embodiments may be omitted.

[0144] Referring to FIG. 10, in step S1010, the first device may obtain at least one of reception delay interval information or reception angle interval information related to a target sensing area. In step S1020, the first device may perform sensing for the target sensing area based on at least one of the reception delay interval information or the reception angle interval information.

[0145] For example, based on relative position information between the first device and the target sensing area, the reception delay interval information and the reception angle interval information may be set.

[0146] For example, monitoring of a sensing signal reflected by a target sensing area can be performed within a target interval set based on at least one of the reception delay interval information or the reception angle interval information.

[0147] For example, the reception delay interval information may include a time interval set based on the reception time of a sensing signal related to the target sensing area or a time interval set based on the line-of-sight (LoS) related to the target sensing area.

[0148] For example, the above-mentioned reception angle interval information may include an angle interval set based on the reception angle of a sensing signal related to the target sensing area or an angle interval set based on the LoS related to the target sensing area.

[0149] For example, at least one of the reception delay interval information or the reception angle interval information may include a guard interval set based on the mobility of the first device.

[0150] For example, whether to report a sensing result obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information may be based on the mobility and threshold value of the first device.

[0151] For example, based on the fact that the mobility of the first device is above a threshold value, it may be determined that the reception delay interval information or the reception angle interval information is invalid.

[0152] For example, whether to report a sensing result obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information may be based on the amount of change and threshold of the sensing result.

[0153] For example, based on the fact that the amount of change in the sensing result obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information is greater than or equal to a threshold value, it may be determined that the reception delay interval information or the reception angle interval information is invalid.

[0154] For example, based on at least one of the reception delay interval information or the reception angle interval information, signals other than the sensing signal associated with the target sensing area may be filtered.

[0155] Additionally, for example, the first device may acquire reception frequency interval information related to the target sensing area. For example, the measurement of the target sensing area may be performed based on at least one of the reception delay interval information, the reception angle interval information, or the reception frequency interval information.

[0156] For example, the above-mentioned receiving frequency interval information may include a frequency offset interval set based on the center frequency of the sensing signal associated with the target sensing area.

[0157] The proposed method above may be applied to a device according to various embodiments of the present disclosure. First, a processor (102) of a first device (100) may control a transceiver (106) to acquire at least one of reception delay interval information or reception angle interval information related to a target sensing area.

[0160] According to one embodiment of the present disclosure, a non-transient computer-readable storage medium recording instructions may be provided. For example, when the instructions are executed, the first device may: acquire at least one of reception delay interval information or reception angle interval information related to a target sensing area; and perform sensing of the target sensing area based on at least one of the reception delay interval information or the reception angle interval information.

[0161] FIG. 11 illustrates a method in which a second device performs wireless communication 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.

[0162] Referring to FIG. 11, in step S1110, the second device may transmit to the first device at least one of reception delay interval information or reception angle interval information related to a target sensing area. In step S1120, the second device may receive a sensing result for the target sensing area from the first device. For example, the sensing result may be obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information.

[0163] The proposed method above may be applied to a device according to various embodiments of the present disclosure. First, the processor (202) of the second device (200) may control the transceiver (206) to transmit at least one of reception delay interval information or reception angle interval information related to a target sensing area to the first device. Then, the processor (202) of the second device (200) may control the transceiver (206) to receive a sensing result for the target sensing area from the first device. For example, the sensing result may be obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information.

[0164] According to one embodiment of the present disclosure, a second device configured to perform wireless communication may be provided. For example, the second device may include at least one transceiver; at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on the instructions executed by the at least one processor, the second device may: transmit to the first device at least one of reception delay interval information or reception angle interval information related to a target sensing area; and receive a sensing result for the target sensing area from the first device. For example, the sensing result may be obtained within a target interval configured based on at least one of the reception delay interval information or the reception angle interval information.

[0165] According to one embodiment of the present disclosure, a processing device configured to control a second device may be provided. For example, the processing device may include at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on the instructions executed by the at least one processor, the second device may: transmit to the first device at least one of reception delay interval information or reception angle interval information related to a target sensing area; and receive a sensing result for the target sensing area from the first device. For example, the sensing result may be obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information.

[0166] According to one embodiment of the present disclosure, a non-transient computer-readable storage medium recording instructions may be provided. For example, when the instructions are executed, the second device may: transmit to the first device at least one of reception delay interval information or reception angle interval information related to a target sensing area; and receive a sensing result for the target sensing area from the first device. For example, the sensing result may be obtained within a target interval set based on at least one of the reception delay interval information or the reception angle interval information.

[0167] According to various embodiments of the present disclosure, by having a receiver perform sensing on a target interval set based on a target sensing area, only specific areas related to the target sensing area can be selectively sensed in the time, space, and / or frequency domains. In this case, for example, reflection components formed by a background environment, a stationary object, or other moving object unrelated to the target sensing area can be prevented from being included in the sensing result, thereby improving the sensing reliability and accuracy of the target sensing area. Alternatively, for example, by performing sensing using a reception delay interval, a reception angle interval, and a frequency interval set based on the reception time, reception angle, and center frequency of the sensing signal, respectively, resources can be concentrated only on the area where the target sensing area is expected to exist, without the need to sense the entire delay interval, the omnidirectional angle area, and the entire Doppler interval. This reduces the sensing throughput and allows for higher detection performance and tracking accuracy to be achieved with the same resources.

[0185] FIG. 14 shows a signal processing circuit for a transmission signal according to one 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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0186] Referring to FIG. 14, 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. 14 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 13. The hardware elements of FIG. 14 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 13. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 13. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 13, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 13.

[0187] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 14. 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).

[0188] 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.

[0189] 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.

[0190] 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. 14. For example, a wireless device (e.g., 100, 200 in FIG. 13) 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.
