[0039] FIG. 1 illustrates a device-to-device communication procedure according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure.

[0040] Referring to FIG. 1, in step S101, a first device and a second device can perform synchronization. For example, the first device can be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device can be a base station, a network, a RAN node, an NTN node / cell, a TRP, a terminal and / or at least one of the devices proposed in the present disclosure. For example, the first device can perform an initial cell search operation. For example, the first device can detect at least one synchronization signal transmitted by the second device according to a predefined rule. Here, for example, the synchronization signal can include a plurality of synchronization signals classified according to a structure or purpose (e.g., a primary synchronization signal, a secondary synchronization signal, etc.). Through this, the first device can identify the boundaries of the frame, subframe, time unit, slot, and / or symbol of the second device, and the first device can obtain information about the second device (e.g., a cell identifier).

[0041] In step S103, the first device can obtain system information transmitted by the second device. For example, the system information may include information related to the properties, characteristics, and / or capabilities of the second device required to connect to the second device and use the service. For example, the system information may be classified according to content (e.g., whether it is essential for connection), transmission structure (e.g., the channel used, whether it is provided on-demand), etc. For example, the system information may be classified into a master information block (MIB) and a system information block (SIB). For example, if necessary, the first device may transmit a signal requesting system information before receiving the system information. For example, the request and provision of system information may be performed after a random access procedure described below.

[0042] In step S105, the first device and the second device can perform a random access procedure. For example, the first device can transmit and / or receive at least one message (e.g., a random access preamble, a random access response message, etc.) for the random access procedure based on information related to a random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device can transmit a preamble (e.g., Msg1) through the random access channel, the first device can receive a random access response message (e.g., Msg2), the first device can transmit a message (e.g., Msg3) including information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device can receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be sent and received as one message (e.g., MsgA), and / or Msg2 and Msg4 can be sent and received as one message (e.g., MsgB).

[0043] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer that controls a connection (e.g., a radio resource control (RRC) layer), a layer that handles mapping between logical channels and transport channels (e.g., a media access control (MAC) layer), a layer that handles physical channels (e.g., a physical (PHY) layer), etc. For example, the first device and the second device may perform at least one of signaling for establishing a connection, signaling for determining settings related to communication, and / or signaling for indicating allocated resources. For example, the control information may be signaled / transmitted via a control channel. For example, the control information and / or the control channel may be used to schedule at least one of data, a data channel (e.g., a shared channel), and / or control information on the data channel.

[0044] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process, transmit, and / or receive data based on signaling of control information. For example, when transmitting data, the first device or the second device may perform at least one of channel encoding, rate matching, scrambling, constellation mapping, layer mapping, waveform modulation, antenna mapping, and / or resource mapping on the information bits. For example, when receiving data, the first device or the second device may perform at least one of signal extraction from resources, waveform demodulation for each antenna, signal arrangement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0045] For example, the layers of a radio interface protocol between a first device and a second device can be divided into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, a physical layer belonging to the first layer can provide an information transfer service using a physical channel, and an RRC (radio resource control) layer located in the third layer can play a role in controlling radio resources between the first device and the second device. For this purpose, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0046] FIG. 2 illustrates a radio protocol architecture according to an embodiment of the present disclosure. The embodiment of FIG. 2 can be combined with various embodiments of the present disclosure. For example, (a) of FIG. 2 may illustrate a radio protocol stack of a user plane for uplink communication or downlink communication, and (b) of FIG. 2 may illustrate a radio protocol stack of a control plane for uplink communication or downlink communication. For example, (c) of FIG. 2 may illustrate a radio protocol stack of a user plane for device-to-device communication, and (d) of FIG. 2 may illustrate a radio protocol stack of a control plane for device-to-device communication.

[0047] For example, the physical layer can provide information transmission services to upper layers using physical channels. For example, the physical layer can be connected to the upper layer, the medium access control (MAC) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through the transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted over the wireless interface. For example, data can be transmitted between different physical layers (e.g., between the physical layers of a first device and a second device) through a physical channel. For example, the physical channel can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and time and frequency can be utilized as radio resources.

[0048] For example, the MAC layer can provide services to the upper layer, the radio link control (RLC) layer, through logical channels. For example, the MAC layer can provide a mapping function from multiple logical channels to multiple transport channels. For example, the MAC layer can provide a logical channel multiplexing function by mapping multiple logical channels to a single transport channel. For example, the MAC sublayer can provide data transmission services on logical channels.

[0049] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee the various quality of service (QoS) required by radio bearers (RBs), the RLC layer can provide three operating modes: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat request (ARQ).

[0050] For example, the RRC (radio resource control) layer can be defined only in the control plane. For example, the RRC layer can be responsible for controlling logical channels, transport channels, and physical channels in relation to the configuration, re-configuration, and release of radio bearers. For example, an RB can mean a logical path provided by a first layer (e.g., a physical layer) and a second layer (e.g., a MAC layer, an RLC layer, a PDCP (packet data convergence protocol) layer, a SDAP (service data adaptation protocol) layer, etc.) for data transmission between a first device and a second device.

[0051] For example, the functions of the PDCP layer in the user plane may include forwarding of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include forwarding of control plane data and ciphering / integrity protection.

[0052] For example, establishing an RB can refer to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. For example, RBs can be divided into two types: signaling radio bearers (SRBs) and data radio bearers (DRBs). For example, SRBs can be used as a channel to transmit RRC messages in the control plane, while DRBs can be used as a channel to transmit user data in the user plane.

[0053] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) for transmitting system information, and / or a downlink shared channel (SCH) for transmitting user traffic or control messages. For example, traffic or control messages of a downlink multicast or broadcast service may be transmitted through the downlink SCH, or may be transmitted through a separate downlink multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) for transmitting initial control messages, and / or an uplink shared channel (SCH) for transmitting user traffic or control messages. For example, a logical channel located above a transmission channel and mapped to the transmission channel may include at least one of a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and / or a multicast traffic channel (MTCH).

[0054] FIG. 3 illustrates the structure of a wireless frame according to an embodiment of the present disclosure. The embodiment of FIG. 3 can be combined with various embodiments of the present disclosure.

[0055] Referring to FIG. 3, for example, a radio frame may be used in uplink transmission, downlink transmission, and / or device-to-device transmission. For example, a radio frame may have a length of 10 ms and may be defined as two 5 ms half-frames (HF). For example, a half-frame may include five 1 ms subframes (SF). For example, a subframe may be divided into one or more slots, and the number of slots within a subframe may be determined according to a subcarrier spacing (SCS). For example, each slot may include 12 or 14 OFDM (A) symbols, depending on a cyclic prefix (CP).

[0056] For example, when normal CP is used, each slot can contain 14 symbols. For example, when extended CP is used, each slot can contain 12 symbols. Here, for example, the symbols can contain OFDM symbols (or CP-OFDM symbols), single carrier-FDMA (SC-FDMA) symbols (or Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) symbols).

[0057] Table 2 below shows the number of symbols per slot (N) depending on the SCS setting (u) when normal CP or extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot ) is an example.

[0058] CP type SCS (15*2u )N slot symb N frame,u slot N subframe,u slot Normal CP15kHz (u=0)1410130kHz (u=1)1420260kHz (u=2)14404120kHz (u=3)14808240kHz (u=4)1416016Extended CP60kHz (u=2)12404

[0059] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single terminal. Accordingly, the (absolute time) interval of time resources (e.g., subframes, slots, or transmit time intervals (TTIs)) composed of the same number of symbols may be set differently between the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTIs, etc. may be referred to as time units.

[0060] For example, multiple numerologies, or SCSs, may be supported to support various services. For example, a 15 kHz SCS may support wide areas in traditional cellular bands, while a 30 kHz / 60 kHz SCS may support dense urban areas, lower latency, and wider carrier bandwidth. For example, a 60 kHz or higher SCS may support bandwidths greater than 24.25 GHz to overcome phase noise.

[0061] FIG. 4 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 4 can be combined with various embodiments of the present disclosure.

[0062] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain, and may correspond to one numerology (e.g., SCS, CP length, etc.). For example, a carrier may include at most N BWPs (where N is a positive integer). For example, data communication may be performed through an activated BWP. For example, each element may be referred to as a resource element (RE) in the resource grid, and one complex symbol may be mapped to it.

[0063] For example, a BWP may be a contiguous set of PRBs in a given numerology. For example, a PRB may be selected from a contiguous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0064] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the UE may not monitor the downlink radio link quality in a DL BWP other than the active DL BWP on the PCell (primary cell). For example, the UE may not receive a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), or a channel state information-reference signal (CSI-RS) (except for radio resource management (RRM)) outside of the active DL BWP. For example, the UE may not trigger channel state information (CSI) reporting for an inactive DL BWP. For example, the UE may not transmit a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) outside of the active UL BWP. For example, for downlink, the initial BWP can be given as a set of consecutive resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For uplink, for example, the initial BWP can be given by the system information block (SIB) for the random access procedure. For example, the default BWP can be set by a higher layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if a terminal does not detect DCI (downlink control information) for a certain period of time, the terminal may switch its active BWP to a default BWP.

[0065] FIG. 5 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 5 can be combined with various embodiments of the present disclosure. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0066] Referring to FIG. 5, for example, a common resource block (CRB) may be a carrier resource block numbered from one end of a carrier band to the other, and a PRB may be a numbered resource block within each BWP. For example, point A may indicate a common reference point for a resource block grid.

[0067] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP ) can be set by. For example, point A can be an outer reference point of the PRB of a carrier where subcarrier 0 of all numerologies (e.g., all numerologies supported by the network on that carrier) aligns. For example, the offset can be the PRB spacing between the lowest subcarrier in a given numerology and point A. For example, the bandwidth can be the number of PRBs in a given numerology.

[0068] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to an embodiment of the present disclosure. The embodiment of FIG. 6 can be combined with various embodiments of the present disclosure.

[0069] As core implementation technologies of the 6G system, technologies such as artificial intelligence (AI), THz (terahertz) communication, optical wireless technology, free-space optical transmission (FSO) backhaul networks, massive MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0070] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. For example, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a key role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. AI can also facilitate rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0071] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by using sub-THz communication with wide bandwidths and applying advanced massive MIMO technology. THz waves, also known as sub-millimeter waves, typically refer to the frequency range between 0.1 THz and 10 THz, with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz to 300 GHz band (sub-THz band) is considered a key part of the THz spectrum for cellular communications. Adding the sub-THz band to the mmWave band will increase the capacity of 6G cellular communications. Among the defined THz bands, 300 GHz to 3 THz lies in the far infrared (IR) frequency band. While part of the optical band, the 300 GHz to 3 THz band lies at the boundary of the optical band, immediately following the RF band. Therefore, this 300 GHz to 3 THz band exhibits similarities to RF. Key characteristics of THz communications include (i) the widely available bandwidth to support very high data rates and (ii) the high path loss that occurs at high frequencies (requiring highly directional antennas). The narrow beamwidths generated by highly directional antennas reduce interference. The small wavelength of THz signals allows for a significantly larger number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array technologies to overcome range limitations.

[0085] Advanced Air Mobility (AAM): AAM can be a broad concept encompassing urban air mobility (UAM), regional air mobility (RAM), and uncrewed aerial systems (UAS). For example, AAM can include UAM, RAM, UAS, and uncrewed aerial vehicles (UAVs).

[0086] - Autonomous driving (self-driving): V2X (vehicle to everything), a key element in building autonomous driving infrastructure, can be a technology that allows cars to communicate and share with various elements on the road for autonomous driving, such as vehicle to vehicle (V2V) wireless communication and vehicle to infrastructure (V2I) wireless communication.

[0087] Non-terrestrial network (NTN): NTN can refer to a network or network segment that utilizes radio frequency (RF) resources mounted on satellites (or UAS platforms). NTN services may be considered to secure wider coverage or provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0088] - Integrated sensing and communication (ISAC)

[0089] - Reconfigurable intelligent surface (RIS): RIS can be used to manipulate and enhance signal propagation in wireless communication environments. For example, a RIS can be composed of many small antennas, or metasurfaces, arranged on a surface, each of which can actively control the phase, amplitude, polarization, etc. of the reflected signal. For example, a RIS can improve signal reception by controlling the path, phase, and / or intensity of the propagating signal. For example, in the case of a RIS, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For example, because a RIS can be reconfigured to suit different environments, it can meet diverse communication requirements and operate effectively in dynamic network environments.

[0090] 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.

[0091] Referring to FIG. 7, NTN communication can be performed based on satellite networks, high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS), terminals capable of aerial communication (e.g., AAM), etc. For example, to improve coverage, etc., devices such as satellite networks, HIBS, terminals capable of aerial communication (e.g., AAM), etc. can act as relays. For example, AAMs can communicate with base stations, satellite networks, etc., and / or AAMs can communicate directly with terminals, other AAMs, etc.

[0092] Below, the integrated sensing and communication (ISAC) mentioned above is described in detail.

[0093] Integrated Sensing and Communications (ISAC) 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 environment and / or the characteristics of objects within the environment. Because radio frequency sensing does not require a device to connect to the object through a network, it can provide services for object positioning without a device. The ability to obtain range, velocity, and angle information from radio frequency signals can enable a wide range of new capabilities, such as various object detection, object recognition (e.g., vehicles, humans, animals, UAVs), and high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to a variety of industries (e.g., unmanned aerial vehicles, smart homes, V2X, factories, railways, public safety, etc.), enabling applications 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 can 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 of wireless sensing signals. Therefore, wireless sensing may provide an opportunity to enhance existing communication systems from a communication network to a wireless communication and sensing network.

[0142] Meanwhile, in a UE-UE sensing operation, when an Rx entity determines a target sensing area (TSA) and performs sensing, it is necessary to define the sensing operation. In addition, according to the prior art, a Tx UE may transmit a sensing signal (or a sensing RS (reference signal)) to be transmitted for a sensing service to a target sensing area (TSA) related to the sensing service (or in the direction of the target sensing area) without considering the distance between the Tx UE and the Tx UE itself. In this case, the following problems may occur. For example, even if a sensing signal transmitted by a Tx UE to a target sensing area is reflected from the target sensing area and received by the Rx UE, if the distance between the Tx UE and the target sensing area exceeds a certain level, the reception quality of the sensing signal may deteriorate due to signal attenuation (path loss) or multipath fading. In this case, for example, even if sensing is performed for a target sensing area based on a sensing signal received by the Rx UE, the reliability of the sensing result for the target sensing area may be lowered and the quality of a sensing service related to the target sensing area based on the sensing result may be degraded.And, for example, if a sensing service related to a target sensing area requires a high level (e.g., high priority or low latency) of QoS requirements, the farther the distance between the Tx UE and the target sensing area, the more likely it is that the sensing signal to be transmitted by the Tx UE and / or the sensing result to be generated by the Rx UE based on the sensing signal will not satisfy the requirement(s) required by the sensing service, and therefore, the Tx UE may need to re-perform settings related to transmission of the sensing signal (e.g., transmission power setting, transmission resource selection, transmission beam selection, etc.). And, due to this, unnecessary power consumption of the Tx UE and / or the Rx UE may occur, inefficiency in use of time / frequency resources may occur, and service quality may be degraded due to delay.

[0143] In the present disclosure, in a UE-UE sensing operation, when an Rx entity determines a target sensing area (TSA) and performs sensing, a method for indicating a TSA and a method for determining a Tx entity based on the TSA are proposed.

[0144] In addition, the present disclosure proposes a method for transmitting a sensing signal based on a threshold distance or threshold time related to a target sensing area and a device supporting the same.

[0145] For example, in the case of UE-UE bi-static sensing, in which a Tx UE transmits a sensing RS (reference signal), and an Rx UE receives a signal reflected by an object from the sensing RS and performs a measurement on the received sensing RS to perform a sensing operation, the Tx UE and / or the Rx UE can perform UE-BS bi-static sensing through the following operations.

[0146] For example, an Rx UE may determine a TSA and transmit the TSA information to Tx UEs around the TSA.

[0147] For example, the Tx UE that receives the TSA information can determine whether to transmit a sensing RS (reference signal) for performing sensing for the TSA based on a distance between a representative location of the TSA and a location of the Tx UE itself. For example, if the distance between the representative location of the TSA and a location of the Tx UE itself is less than or equal to a threshold value set (in advance) (in a resource pool), the sensing RS can be transmitted for the purpose of sensing for the TSA. Alternatively, for example, if the distance between the representative location of the TSA and a location of the Rx UE itself is greater than a threshold value set (in advance) (in a resource pool), the sensing RS can not be transmitted for the purpose of sensing for the TSA. Alternatively, for example, the threshold value can be determined based on a quality of service (QoS) for a sensing service associated with the sensing RS (e.g., a priority associated with the service, a sensing latency requirement, etc.). Alternatively, for example, the Rx UE may transmit the threshold value to the Tx UE in association with the TSA information.

[0148] For example, the Tx UE may be instructed of a maximum threshold time interval value during which it expects to transmit the sensing RS associated with the TSA. For example, the maximum threshold time interval value may be set (in advance) (per resource pool). Or, for example, the maximum threshold time interval value may be transmitted by the Rx UE to the Tx UE. Or, for example, the maximum threshold time interval value may be determined based on the TSA information. Or, for example, the maximum threshold time interval value may be determined based on an area of ​​the TSA. Or, for example, the Tx UE may divide the location / area indicated by the TSA into one or more sub-TSAs, and form a separate transmission beam for each sub-TSA to transmit the sensing RS.

[0149] For example, a method for determining resources for transmitting sensing RSs while minimizing transmission collisions between the Tx UEs may be as follows.

[0150] For example, the Tx UE can select a resource to transmit the sensing RS based on identifier (ID) information representing the Tx UE. For example, the Tx UE can select a time domain in which to select a final sensing RS transmission resource based on the ID among candidate transmission resources determined based on its own channel sensing, and can randomly determine the final sensing RS transmission resource among candidate transmission resources belonging to the time domain. Or, for example, the Tx UE can divide the candidate transmission resources determined based on channel sensing into N groups (pre-configured in a resource pool), select one group among the N groups based on the ID, and randomly determine the final sensing RS transmission resource among candidate transmission resources belonging to the selected group. For example, the N value can be transmitted from the Rx UE to the Tx UE in conjunction with the TSA information. Alternatively, for example, the Tx UE may transmit to the Rx UE information about candidate transmission resources determined based on its own channel sensing, and the Rx UE may transmit to the Tx UE information about final sensing RS transmission resources to be transmitted by the Tx UE based on the information about the candidate transmission resources received from the Tx UE. For example, when the Rx UE receives information about candidate transmission resources from the one or more Tx UEs, the Rx UE may determine final transmission resources of each Tx UE and transmit information about each final transmission resource to each Tx UE so that the sensing RS transmission resources to be finally transmitted by each Tx UE do not collide with each other in the time and / or frequency domain.

[0151] FIG. 9 illustrates a method for transmitting a sensing signal based on a threshold distance, according to an embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure.

[0152] Referring to FIG. 9, in step S910, a Tx UE (or Tx entity) may receive information related to a target sensing area (TSA) from an Rx UE (or Rx entity). For example, the Rx UE may determine a target sensing area related to a sensing service, and may include the determined target sensing area in information related to the target sensing area and transmit the information to the Tx UE. For example, the information related to the target sensing area may be received through a control channel or a shared channel.

[0153] In step S920, the Tx UE may obtain / determine a distance between the target sensing region and the Tx UE itself. For example, the Rx UE may determine a location of the target sensing region based on the information related to the target sensing region received in step S910. For example, the information related to the target sensing region may include zone ID information related to the target sensing region. In this case, for example, the location of the target sensing region may be determined based on the zone ID information. Alternatively, for example, the information related to the target sensing region may include coordinate information related to the target sensing region and / or radius information from the coordinates. In this case, for example, the location of the target sensing region may be determined based on the coordinate information and the radius information. For example, as described below, the distance between the target sensing region and the Tx UE may be used to determine a reception quality related to a sensing signal to be transmitted by the Tx UE to the target sensing region. Alternatively, for example, the distance between the target sensing area and the Tx UE may be used to determine the reliability of the sensing result for the target sensing area to be measured based on the sensing signal received by the Rx UE when the sensing signal to be transmitted to the target sensing area is reflected from the target sensing area and received by the Rx UE, or to determine whether the sensing result can satisfy the requirements or quality of service (QoS) of the service related to the sensing signal to be transmitted to the target sensing area.

[0154] In step S930, the Tx UE may determine whether to transmit a sensing signal based on the distance between the target sensing area and the Tx UE itself.

[0155] For example, the Tx UE may compare the distance between the target sensing area and the Tx UE itself with a threshold value to determine whether to transmit the sensing signal. In this case, for example, the threshold value may be (pre-)set in a resource pool for transmitting and receiving the sensing signal. Or, for example, the threshold value may be determined based on a requirement or quality of service (QoS) of a sensing service related to the sensing signal (e.g., priority related to a sensing service, latency related to a sensing service, etc.). Or, for example, information related to the threshold value may be included in the information related to the target sensing area by the Rx UE in the above-described step S910 and transmitted to the Tx UE, or may be transmitted to the Tx UE together with the information related to the target sensing area.

[0156] Meanwhile, for example, when the distance is less than or equal to the threshold value, the Tx UE may decide to transmit the sensing signal to the target sensing area. For example, when the distance is less than or equal to the threshold value, the Tx UE may determine that reception quality related to the sensing signal to be transmitted to the target sensing area is good, and therefore, the Tx UE may decide to transmit the sensing signal to the target sensing area. Or, for example, when the distance is less than or equal to the threshold value, the Tx UE may determine that reliability of the sensing result for the target sensing area may be higher than a threshold level, and therefore, the Tx UE may decide to transmit the sensing signal to the target sensing area. Alternatively, for example, if the distance is less than or equal to the threshold value, the Tx UE may determine that the sensing result for the target sensing area can satisfy a requirement or quality of service (QoS) of a sensing service related to the sensing signal, and thus the Tx UE may decide to transmit the sensing signal to the target sensing area.

[0157] Meanwhile, for example, when the distance is greater than the threshold value, the Tx UE may decide not to transmit the sensing signal to the target sensing area. For example, when the distance is greater than the threshold value, the Tx UE may determine that the reception quality related to the sensing signal to be transmitted to the target sensing area is likely to be poor, and therefore, the Tx UE may decide not to transmit the sensing signal to the target sensing area. Or, for example, when the distance is greater than the threshold value, the Tx UE may determine that the reliability of the sensing result for the target sensing area may be lower than a threshold level, and therefore, the Tx UE may decide not to transmit the sensing signal to the target sensing area. Alternatively, for example, if the distance is greater than the threshold value, the Tx UE may determine that the sensing result for the target sensing area does not meet the requirement or quality of service (QoS) of the sensing service related to the sensing signal, and thus the Tx UE may decide not to transmit the sensing signal to the target sensing area.

[0158] In step S940, the Tx UE may transmit the sensing signal to the target sensing area based on the distance between the target sensing area and the Tx UE itself. For example, as described above in step S930, if the distance between the target sensing area and the Tx UE is less than or equal to the threshold value, the Tx UE may transmit the sensing signal to the target sensing area.

[0159] FIG. 10 illustrates a method for transmitting a sensing signal based on a threshold distance or threshold time, according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure.

[0160] Referring to FIG. 10, in step S1010, a Tx UE (or Tx entity) may receive information related to a target sensing area (TSA) from an Rx UE (or Rx entity). For example, the Rx UE may determine a target sensing area related to a sensing service, and may include the determined target sensing area in information related to the target sensing area and transmit it to the Tx UE. For example, the information related to the target sensing area may be received through a control channel or a shared channel.

[0161] In step S1020, the Tx UE may determine whether to transmit a sensing signal based on information related to a threshold time.

[0162] For example, information related to the threshold time may be (pre-)set in a resource pool for transmitting and receiving the sensing signal. Or, for example, information related to the threshold time may be determined based on the target sensing area. In this case, for example, as the size of the target sensing area increases, the threshold time may be set to a smaller value. Or, for example, such as setting or obtaining the above-described threshold value (see the embodiment of FIG. 9), information related to the threshold time may be included in the information related to the target sensing area by the Rx UE and transmitted to the Tx UE, or may be transmitted to the Tx UE together with information related to the target sensing area.

[0163] Meanwhile, for example, the threshold time may be a maximum threshold time during which the Tx UE is expected to transmit a sensing signal to the target sensing region. Or, for example, the threshold time may be a maximum threshold time during which the sensing signal to be transmitted by the Tx UE is expected to be reflected by the target sensing region and received by the Rx UE that transmitted information related to the target sensing region. Or, for example, the threshold time may be a maximum time interval from a time when the Tx UE receives information related to the target sensing region to a time when the Tx UE is expected to transmit a sensing signal to the target sensing region. Or, for example, the threshold time may be a maximum time interval from a time when the Tx UE receives information related to the target sensing region to a time when the Tx UE completes resource selection and / or beamforming for transmitting a sensing signal and is expected to transmit a sensing signal to the target sensing region. Alternatively, for example, the threshold time may be a maximum threshold time during which the quality of service related to the sensing signal to be transmitted by the Tx UE to the target sensing area can be guaranteed.

[0164] Meanwhile, for example, if it is determined that the Tx UE can complete the above-described step(s) within the threshold time, the Tx UE may decide to transmit the sensing signal to the target sensing area. Specifically, for example, if it is determined that the Tx UE can 1) select a resource for transmitting a sensing signal, and 2) transmit the sensing signal to the target sensing area within the threshold time, the Tx UE may decide to transmit the sensing signal to the target sensing area. Or, for example, if it is determined that the Tx UE can 1) perform beam selection and / or beam forming for transmitting a sensing signal, and 2) transmit the sensing signal to the target sensing area based on a transmission beam (Tx beam) within the threshold time, the Tx UE may decide to transmit the sensing signal to the target sensing area. Meanwhile, for example, if the Tx UE determines that it cannot complete the above-described step(s) within the threshold time, the Tx UE may decide not to transmit the sensing signal. In this case, for example, the Tx UE may release the resource selected to transmit the sensing signal.

[0165] Additionally, for example, the Tx UE may consider the distance between the target sensing area and the Tx UE together, as in the embodiment of FIG. 9 described above. For example, the Tx UE may obtain / determine the distance between the target sensing area and the Tx UE, as in step S920 of FIG. 9 described above, and may determine whether to transmit the sensing signal to the target sensing area based on the distance between the target sensing area and the Tx UE itself, as in step S930 of FIG. 9 described above. In this case, for example, if the Tx UE 1) receives information related to a target sensing area within the threshold time, 2) determines a distance between the target sensing area and the Tx UE itself, 3) determines whether the distance is less than or equal to a threshold, 4) performs resource selection and / or beam selection and / or beam forming for transmitting a sensing signal, and 5) determines that the sensing signal can be transmitted to the target sensing area based on the selected resource and / or transmission beam (Tx beam), the Tx UE may decide not to transmit the sensing signal. In this case, for example, the Tx UE may release a resource selected for transmitting the sensing signal.

[0166] In step S1030, the Tx UE may transmit the sensing signal to the target sensing area within the threshold time. Or, for example, the Tx UE may transmit the sensing signal to the target sensing area within the threshold time based on a distance between the target sensing area and the Tx UE itself. In this case, for example, only when it is determined that the distance between the target sensing area and the Tx UE is less than or equal to the threshold value and the Tx UE can transmit the sensing signal to the target sensing area within the threshold time, the Tx UE may transmit the sensing signal to the target sensing area.

[0174] For example, the sensing signal may not be transmitted based on the distance between the first device and the target sensing area being greater than a threshold value.

[0175] For example, the threshold value may be determined based on information related to quality of service (QoS) associated with the sensing signal.

[0176] For example, the sensing signal may be transmitted within a threshold time. For example, the threshold time may be the maximum threshold time within which the first device is expected to transmit the sensing signal. For example, the threshold time may be determined based on information related to the target sensing area. For example, the threshold time may be determined based on the size of the target sensing area.

[0177] For example, the resource for transmitting the sensing signal may be selected based on information related to the ID (identifier) ​​of the first device.

[0178] For example, a resource for transmitting the sensing signal may be randomly selected from among a plurality of candidate resources included in a time domain determined based on information related to the ID of the first device.

[0179] For example, a resource for transmitting the sensing signal may be randomly selected from a candidate resource set determined based on information related to the ID of the first device among one or more candidate resource sets.

[0180] Additionally, for example, the first device may transmit information related to a plurality of candidate resources determined based on sensing to the second device. Furthermore, for example, the first device may receive information related to a first resource selected from the plurality of candidate resources from the second device. For example, the sensing signal may be transmitted based on the first resource.

[0181] For example, based on the target sensing region being divided into a plurality of regions, a first sensing signal may be transmitted through a first beam associated with a first region among the plurality of regions, and a second sensing signal may be transmitted through a second beam associated with a second region other than the first region.

In step S1220, the second device may perform sensing of the target sensing area based on a sensing signal.

[0210] FIG. 15 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 15 may be combined with various embodiments of the present disclosure.

[0211] 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 operations / functions of FIG. 15 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 14. The hardware elements of FIG. 15 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 14. For example, blocks 1010 to 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.

[0212] 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 can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).

[0213] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010). The scramble sequence used for scrambling is generated based on an initialization value, and the initialization value may include ID information of the wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by a precoding matrix W of N*M. Here, N is the number of antenna ports, and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on complex modulation symbols. In addition, the precoder (1040) can perform precoding without performing transform precoding.

[0214] The resource mapper (1050) can map modulation symbols of each antenna port to time-frequency resources. The time-frequency resources can include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. The signal generator (1060) generates a wireless signal from the mapped modulation symbols, and the generated wireless signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) can include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0215] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 15. For example, a wireless device (e.g., 100, 200 of FIG. 14) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
