[0040] FIG. 1 illustrates a device-to-device communication procedure according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0041] 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).

[0042] 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.

[0043] 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).

[0044] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer 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.

[0045] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process, 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.

[0046] 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.

[0047] FIG. 2 illustrates a radio protocol architecture according to an embodiment of the present disclosure. The embodiment of FIG. 2 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. For example, (a) of FIG. 2 may illustrate a radio protocol stack of a user plane for uplink communication or downlink communication, and (b) of FIG. 2 may illustrate a radio protocol stack of a control plane for uplink communication or downlink communication. For example, (c) of FIG. 2 may illustrate a radio protocol stack of a user plane for device-to-device communication, and (d) of FIG. 2 may illustrate a radio protocol stack of a control plane for device-to-device communication.

[0048] 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.

[0049] 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.

[0050] 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).

[0051] 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.

[0052] For example, the functions of the PDCP layer in the user plane may include the forwarding of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include the forwarding of control plane data and ciphering / integrity protection.

[0053] 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.

[0054] 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).

[0055] FIG. 3 illustrates the structure of a wireless frame according to an embodiment of the present disclosure. The embodiment of FIG. 3 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0056] 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).

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

[0058] 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.

[0059] CP type SCS (15*2 u )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

[0060] 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.

[0061] 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.

[0062] FIG. 4 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 4 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0063] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain, and may correspond to 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.

[0064] 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.

[0065] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the 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.

[0066] FIG. 5 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 5 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0067] Referring to FIG. 5, for example, a common resource block (CRB) may be a 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.

[0068] 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.

[0069] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to an embodiment of the present disclosure. The embodiment of FIG. 6 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0070] 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.

[0071] - 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.

[0072] - 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.

[0086] Advanced Air Mobility (AAM): AAM can be a broad concept encompassing urban air mobility (UAM), regional air mobility (RAM), and uncrewed aerial systems (UAS). For example, AAM can include UAM, RAM, UAS, and uncrewed aerial vehicles (UAVs).

[0087] - 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.

[0088] 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.

[0089] - Integrated sensing and communication (ISAC)

[0090] - 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.

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

[0093] Below, the integrated sensing and communication (ISAC) mentioned above is described in detail.

[0094] 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 processing of wireless sensing signals. Therefore, wireless sensing may 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 the embodiments may be omitted. Specifically, FIG. 8 (a) illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and FIG. 8 (b) illustrates an example of sensing using a separated sensing receiver and a sensing transmitter (e.g., bistatic sensing).

[0140] - SL PRS sequence ID

[0141] - SL PRS spatial relation: can be set to SL SSB or DL ​​PRS or UL SRS or UL SRS for positioning or PSCCH DMRS or PSSCH DMRS or PSFCH or SL CSI RS, etc.

[0142] - SL PRS CCH: SL PRS control channel. Can signal SL PRS resource configuration information and resource location, etc.

[0143] Meanwhile, when the terminal has logical channel data and / or MAC CE and / or control message (e.g., PC5-S message, PC5 RRC message) to transmit, the terminal can perform the LCP procedure according to the LCP (logical channel prioritization) priority order.

[0144] For example, the LCP procedure may be as follows. For example, when a terminal has multiple messages or data to transmit (e.g., MAC CE, communication data, (PC5) RRC message), the terminal may first generate a MAC PDU for a message with a higher priority based on priority. For example, when the terminal has a MAC CE and data to transmit, if the destinations of the MAC CE and the data are different, the terminal may first multiplex a message with a higher priority (e.g., MAC CE) into the MAC PDU to generate a MAC PDU. In addition, for example, when the destinations of messages are the same, the terminal may perform a multiplexing operation for generating a MAC PDU by preferentially selecting a message with a higher priority.

[0145] Meanwhile, in conventional communications (e.g., NR Uu or NR SL (sidelink)), the sensing procedure of a device (e.g., a terminal or a base station) was not considered a service. However, since the main purpose of the ISAC service is to quickly detect and distinguish a target object through sensing, it is necessary to classify the sensing procedure (or operation) as a service that must satisfy one QoS requirement (e.g., sensing latency: the time it takes for a terminal that triggers sensing to trigger the sensing procedure and for a receiving terminal to receive the sensing result of the target object, or sensing accuracy, etc.). For example, in ISAC, a sensing behavior of a device (e.g., a terminal or a base station or a sensing management function (SMF)) can be regarded as a service that must satisfy ISAC sensing QoS requirements, and the terminal can perform a sensing behavior (e.g., transmitting a sensing RS (reference signal) and / or receiving a sensing RS) based on the sensing QoS.

[0146] For example, in ISAC, sensing can be considered as a higher layer service that must satisfy sensing QoS (or sensing quality) based on sensing results, and a new QoS for ISAC sensing service can be defined as follows.

[0147] - For example, a new QoS for the ISAC sensing service can be defined as “SQFI (sensing QoS flow ID)”.

[0148] - For example, the value of the SQFI can be classified into 1 to 8 (e.g., depending on the level of the sensing QoS requirement (e.g., sensing accuracy, sensing latency: latency boundary from when sensing is triggered to receiving the sensing result, sensing priority: priority that can be used to determine which sensing service to trigger first based on priority when multiple sensing procedures are required)). For example, the smaller (or higher) the value of the SQFI, the tighter (tighter) (e.g., a sensing service requiring high sensing accuracy, or a sensing service requiring low / lower / lowest sensing latency) the sensing service can be defined.

[0149] Meanwhile, according to the prior art, in order to perform sensing for a target sensing area related to a sensing service, a base station can determine / configure a UE that performs transmission / reception of a sensing RS (e.g., an uplink sensing RS or a downlink sensing RS), and transmit information about the sensing RS or configuration information related to the sensing RS to the UE determined to perform transmission / reception of the sensing RS. However, if only a specific UE determined / configured by the base station is allowed to perform an operation of receiving a sensing RS reflected from a target sensing area, the following problem may occur. For example, due to the mobility of the specific UE determined / configured by the base station (or, if the target sensing area is based on a specific cluster, due to the mobility of the specific cluster), the distance between the specific UE and the target sensing area may exceed a threshold value, or the line of sight (LOS) between the specific UE and the target sensing area may not be secured. In this case, if, for example, only the specific UE determined / configured by the base station is allowed to receive the sensing RS and perform sensing based on the received sensing RS, the reception quality related to the sensing RS may be degraded, or the reliability of sensing for the target sensing area measured based on the received sensing RS and / or the reliability of the measurement result may be degraded. Or, for example, if only the specific UE is determined / configured to receive the sensing RS, only the specific UE may use resources for transmitting and receiving the sensing RS, and thus the efficiency of resource use for sensing the target sensing area may be degraded.Or, for example, if only a specific UE is determined / configured to receive the sensing RS, the specific UE may not be able to cover the entire wide target sensing area, and thus the larger the target sensing area, the lower the reliability of the sensing may be.

[0150] In the present disclosure, a method for transmitting an ISAC sensing reference signal (RS) of a terminal via uplink transmission (e.g., transmission from a terminal to a base station), a method for transmitting an ISAC sensing reference signal (RS) of a base station via downlink transmission (e.g., transmission from a base station to a terminal), and a method for receiving a sensing reference signal via overhearing of an uplink signal (e.g., sensing RS transmission via uplink) and a downlink signal (e.g., sensing RS transmission via downlink) transmitted by a neighboring terminal of the terminal within a sensing area, and a device supporting the same are proposed.

[0151] 1. Definition of uplink CG (configured grant) for transmitting ISAC sensing RS

[0152] 1-1. Type 1 uplink CG (configured grant) for transmitting ISAC sensing RS

[0153] For example, the base station can configure the uplink CG (configured grant) for ISAC sensing RS transmission by QoS (e.g., sensing period) or sensing priority or ISAC-CS (configured scheduling)-RNTI (radio network temporary identifier) ​​or sensing service group (or sensing service group identifier) ​​(e.g., uplink resource period, uplink resources per period, QoS ID of sensing service that can use uplink CG (configured grant), sensing priority, or sensing service distinguishing identifier that can use uplink CG (configured grant) (e.g., ISAC-CS-RNTI)) and transmit it to the terminal (e.g., via a dedicated RRC message, system information, or pre-configuration). For example, the terminal may transmit the QoS (e.g., QoS identifier associated with the sensing service and / or sensing RS, sensing cycle) or sensing service priority or ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​of the sensing service (or sensing RS) to the base station through assistance information (e.g., UE assistance information) so that the base station can set uplink CG for ISAC sensing RS transmission to the terminal.Additionally, for example, the terminal may be allocated an ISAC-CS-RNTI (e.g., identifier information for distinguishing a sensing service and / or a sensing RS associated with a sensing service so that the base station can allocate transmission resources for a specific sensing service and / or a sensing RS associated with the sensing service to the terminal) from the base station through a random access procedure. For example, when an ISAC sensing RS transmission via uplink transmission is triggered, the terminal may transmit a periodic sensing RS to the base station using an ISAC sensing UL (uplink) CG. In addition, for example, a terminal (e.g., a sensing RS transmitting terminal and / or a sensing RS receiving terminal) interested in the same sensing service (e.g., a sensing service distinguished by QoS (e.g., QoS identifier associated with the sensing service and / or sensing RS, sensing cycle) or sensing service priority or ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​of the same sensing service (or sensing RS) may overhear an uplink sensing RS transmitted by a neighboring terminal at every uplink CG cycle set by QoS (e.g., QoS identifier associated with the sensing service and / or sensing RS, sensing cycle) or sensing service priority or ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​of the same sensing service (or sensing RS) when the ISAC sensing RS monitoring operation is triggered.In addition, for example, when there is a pending sensing RS transmission, the sensing RS transmitter may cancel the pending sensing RS transmission if the sensing RS associated with the sensing service (or sensing RS) of which it is interested has overheard a threshold value or more, the sensing RS associated with the sensing service having the same QoS (e.g., QoS identifier, sensing cycle associated with the sensing service and / or sensing RS) or the sensing service priority or the ISAC-CS-RNTI or the sensing service group (or sensing service group identifier).

[0154] 1-2. Type 2 uplink CG (configured grant) for transmitting ISAC sensing RS

[0155] For example, the base station can configure the uplink CG (configured grant) for ISAC sensing RS transmission by QoS (e.g., sensing cycle) or sensing priority of the sensing service (or sensing RS) or by ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​(e.g., uplink resource cycle, uplink resources per cycle, QoS ID of the sensing service that can use the uplink CG (configured grant), sensing priority, or sensing service distinguishing identifier that can use the uplink CG (configured grant) (e.g., ISAC-CS-RNTI)) and transmit it to the terminal (e.g., via a dedicated RRC message, system information, or pre-configuration). In addition, for example, the base station can activate or deactivate ISAC sensing RS transmission for QoS (e.g., QoS identifier associated with the sensing service and / or sensing RS, sensing cycle) or sensing service priority or ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​of a specific sensing service (or sensing RS) via downlink control information (DCI) (or physical downlink control channel (PDCCH)). For example, the terminal can transmit periodic ISAC sensing RS to the base station using uplink CG when receiving ISAC sensing CG type 2 activation (e.g., via PDCCH). In addition, for example, the terminal can stop transmission operation of periodic ISAC sensing RS when receiving ISAC sensing CG type 2 deactivation (e.g., via PDCCH).Alternatively, for example, a UE that receives an ISAC sensing CG type 2 activation may notify the surrounding sensing area of ​​the start of ISAC sensing RS transmission (e.g., via broadcast or groupcast), and other terminals within the sensing area that receive this notification message may overhear the sensing RS message transmitted by the surrounding terminal within the sensing area (e.g., perform overhearing at every CG cycle).

[0156] 2. Downlink SPS (semi-persistent scheduling) for sensing ISAC RS

[0157] For example, the base station can configure downlink SPS (semi-persistent scheduling) resources for ISAC sensing RS transmission by QoS (e.g., sensing cycle) or sensing priority of sensing service (or sensing RS) or ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​(e.g., downlink resource cycle, downlink resources by cycle, sensing service QoS ID that can monitor DL ​​(downlink) sensing RS through downlink SPS (semi-persistent scheduling), sensing priority, or sensing service distinguishing identifier that can use downlink SPS (semi-persistent scheduling) (e.g., ISAC-CS-RNTI)) and transmit them to the terminal (e.g., via a dedicated RRC message, system information, or pre-configuration). Additionally, for example, the base station can activate or deactivate downlink ISAC sensing RS transmission for QoS (e.g., QoS identifier associated with the sensing service and / or sensing RS, sensing cycle) or sensing service priority or ISAC-CS-RNTI or sensing service group (or sensing service group identifier) ​​of a specific sensing service (or sensing RS) via DCI (or PDCCH). For example, the terminal can receive the ISAC sensing RS transmitted by the base station every DL SPS cycle when receiving a downlink SPS (semi-persistent scheduling) activation for downlink sensing RS transmission (e.g., via PDCCH).Additionally, for example, the UE may stop receiving periodic ISAC sensing RSs upon receiving DL SPS deactivation for DL ​​ISAC sensing RSs transmitted by the base station (e.g., via PDCCH). Alternatively, for example, the UE, which has received DL SPS activation for downlink sensing RSs, may notify the surrounding sensing areas of the start of downlink ISAC sensing RS transmission (e.g., via broadcast or groupcast), and other UEs within the sensing area that have received this notification message may overhear the downlink sensing RS messages transmitted by the base station within the sensing area (e.g., perform overhearing at every DL SPS period).

[0158] 3. Assistance information for ISAC sensing

[0159] For example, the terminal may include the following information in the UE assistance information and transmit it to the base station, which may help the base station set the uplink ISAC sensing RS transmission resources and / or the downlink (DL) assignment for the downlink ISAC sensing RS transmission.

[0160] - Sensing service QoS information (e.g., sensing priority, required latency budget, sensing coverage, sensing periodicity, required sensing accuracy, etc.)

[0161] Alternatively, for example, a UE may report the following information to a base station, a transmission reception point (TRP), or a sensing management function (SMF) so that the base station, the transmission reception point (TRP), or the sensing management function (SMF) can allocate resources appropriate for the sensing QoS to UEs with different sensing QoS (e.g., type 1 UE and type 2 UE).

[0162] For example, the sensing QoS for the ISAC service is as follows.

[0163] - Detection: detection probability, false alarm probability

[0164] - Localization: Localization of static objects, QoS parameters of localization (e.g., time delay, angle of arrival)

[0165] - Tracking: Tracking the state variation (e.g. range, angle, speed, etc.) of a moving target (e.g. vehicle or drone).

[0166] For example, the auxiliary information transmitted for ISAC service operation of a UE based on Uu signaling is as follows.

[0167] - Auxiliary information for ISAC sensing services based on detection QoS (e.g., auxiliary information to be transmitted when transmitting sensing signals for detection (e.g., sensing reference signals or sensing measurement reports))

[0168] - QoS type information (e.g., detection), detection QoS level (or requirement of false alarm probability, or requirement of detection probability)

[0169] - Allocate resources by judging the level of interference with communication resources based on the detection QoS level (e.g., allocate support that can minimize interference with communication signals for services with tight requirements on false alarm probability).

[0170] - Auxiliary information for localization QoS (e.g., auxiliary information to be transmitted when transmitting sensing signals for the purpose of localization measurement (e.g., sensing reference signal or sensing measurement report))

[0171] - QoS type information (e.g., localization), localization accuracy level

[0172] - Auxiliary information for tracking QoS (e.g., auxiliary information to be transmitted when transmitting sensing signals (e.g., sensing reference signals or sensing measurement reports) for the purpose of tracking a moving object)

[0173] - QoS type information (e.g., tracking), tracking object information (e.g., vehicle or drone), tracking interval

[0174] For example, the auxiliary information transmitted for ISAC service operation of a UE based on sidelink signaling is as follows.

[0175] - Auxiliary information for ISAC sensing services based on detection QoS (e.g., auxiliary information to be transmitted when transmitting sidelink sensing signals for detection (e.g., sensing reference signals or sensing measurement reports))

[0176] - QoS type information (e.g., detection), detection QoS level (or requirement of false alarm probability, or requirement of detection probability)

[0177] - Allocate resources by judging the level of interference with communication resources based on the detection QoS level (e.g., allocate support that can minimize interference with communication signals for services with tight requirements on false alarm probability).

[0178] - Auxiliary information for localization QoS (e.g., auxiliary information to be conveyed when transmitting sidelink sensing signals for the purpose of localization measurement (e.g., sensing reference signal or sensing measurement report))

[0179] - QoS type information (e.g., localization), localization accuracy level

[0180] - Auxiliary information for tracking QoS (e.g., auxiliary information to be transmitted when transmitting sidelink sensing signals (e.g., sensing reference signals or sensing measurement reports) for the purpose of tracking a mobile device)

[0181] - QoS type information (e.g., tracking), tracking object information (e.g., vehicle or drone), tracking interval

[0182] 4. DG (dynamic grant) for sensing RS transmission

[0183] (Option #1) For example, the terminal may be allocated uplink ISAC sensing RS transmission resources by transmitting a sensing RS request MAC CE (e.g., including a destination (DST) ID and a sensing RS priority and / or a sensing QoS flow ID and / or an ISAC-sensing-RNTI) to the base station.

[0184] (Option #2) For example, by defining specific SR (scheduling request) configurations for sensing RSs (e.g., one SR configuration per ISAC sensing RS transmission, or each SR configuration per each sensing QoS flow ID and / or ISAC-sensing-RNTI), the UE can request sensing RS resources from the base station only through SR transmissions without transmitting buffer status reports (BSRs).

[0185] (Option #3) BSR (buffer status report) format for ISAC sensing RS transmission: For example, the BSR transmitted by a terminal to allocate resources for ISAC sensing RS transmission may include the following information.

[0186] - Sensing RS reception destination ID, sensing QoS flow ID (or sensing service priority, or sensing RS priority, or ISAC-sensing-RNTI)

[0187] Meanwhile, when considering the mobility of a terminal transmitting / receiving a sensing RS (reference signal) (e.g., a change in the target sensing area (TSA) where the terminal can transmit / receive the sensing RS), always using the same grant (or transmission resource, or resource pool) may not be optimal in terms of interference control related to the sensing RS or use of a sensing beam suitable for the TSA. In consideration of this, for example, a different grant (or transmission resource, or resource pool) may be set according to the "TSA (target sensing area)", the "index of the sensing beam", the "reference signal (and / or RSRP value of the reference signal) used to determine the sensing beam", the "location of the terminal transmitting / receiving the sensing RS", the "sensing operation type (e.g., between terminals or between the terminal and the TRP)", etc. Alternatively, for example, the TRP may signal multiple grant (or transmission resource, or resource pool) candidates to be used for transmitting / receiving the sensing RS to the terminal transmitting / receiving the sensing RS, and the terminal transmitting / receiving the sensing RS may select the grant (or transmission resource, or resource pool) to be finally used through interference measurement on the grant (or transmission resource, or resource pool), etc. (and / or report the selected grant (or transmission resource, or resource pool) information to the TRP). For example, when the terminal transmitting the sensing RS can no longer perform sensing RS transmission related to TSA to the terminal receiving the sensing RS due to its mobility, etc., the terminal may transmit release information for the related grant (or transmission resource, or resource pool).

[0188] Alternatively, for example, information about a sensing signal may be shared with neighboring UEs to enable other UEs to overhear a sensing RS (S-RS) transmitted / received via uplink or downlink between a base station and a UE. For example, a base station may transmit information about a sensing signal for a sensing RS (S-RS) configured for a specific UE (e.g., RNTI information for configuring uplink or downlink resources and / or the uplink or downlink resource information) to a neighboring UE of the UE (e.g., a UE subscribed to the same sensing service (or a UE interested in the same sensing service), or a UE located in the same zone (or area)). Or, for example, when a base station transmits information about a sensing signal for a sensing RS (S-RS) set for a specific terminal (e.g., RNTI information for setting uplink or downlink resources and / or the uplink or downlink resource information) to the terminal, the terminal can transmit information about the sensing signal received from the base station to its neighboring terminals.For example, the neighboring terminal may overhear a downlink sensing RS transmitted by the base station to a neighboring terminal (a specific terminal neighboring the neighboring terminal that received the sensing signal information) and / or an uplink sensing RS transmitted by the neighboring terminal (a specific terminal neighboring the neighboring terminal that received the sensing signal information) to the base station using the received sensing signal information (e.g., RNTI information for setting uplink or downlink resources and / or the uplink or downlink resource information). Additionally, for example, a UE that overhears the uplink sensing RS or downlink sensing RS may include information (e.g., RNTI and / or UE / cell ID and / or time stamp) about which UE the sensing RS (e.g., uplink sensing RS or downlink sensing RS) was measured in a sensing RS measurement report and transmit the information to a sensing client, a base station, or a network. For example, since a UE that overhears the uplink sensing RS or downlink sensing RS is an entity that was not included in the scheduling for the sensing operation, the UE may request the base station for a resource to report a measurement report, and the base station may set a resource in response to the request.In this case, for example, the transmission resource request message for the sensing RS measurement report transmitted by the overhearing UE may include information (e.g., RNTI and / or UE / cell ID) about which UE the sensing RS (e.g., uplink sensing RS or downlink sensing RS) was measured for.

[0189] In addition, for example, when a sensing signal using a downlink or uplink resource set by a base station for sensing a TSA at the request of a specific UE (UE 1) is overheard by another UE (UE 2), the sensing management function (SMF) will receive the detection result for an object in the TSA sensed by the UE 1 and the detection result for an object in the TSA sensed by the UE 2, which may be different from the TSA sensed by the UE 1. Depending on whether the sensing performance for the same object is to be improved through multi-static sensing from the sensing results by one or more UEs or whether the sensing will be of the nature of environment sensing for other multiple TSAs, the required operations and signaling may differ. For example, for the above purpose, the UE (UE 1 or UE 2) can include its own location information in the measurement report it reports, and the SMF can estimate information about the TSA sensed by the UE (UE 1 or UE 2) from the location information.

[0190] FIG. 9 illustrates a method for overhearing a downlink sensing reference signal according to an 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.

[0191] Referring to FIG. 9, in order to perform bi-static sensing for a sensing region (or a target sensing region), a base station may transmit configuration information for downlink sensing (or information related to a downlink sensing reference signal). Or, for example, the base station may broadcast system information for sensing (e.g., a system information block (SIB)) via RRC. For example, the base station may transmit the configuration information for downlink sensing (or information related to a downlink sensing reference signal) including information specifying a UE that will receive a downlink sensing reference signal in order to perform sensing for the sensing region (or the target sensing region). For example, when the base station specifies UE B as a UE that receives a downlink sensing reference signal, the configuration information for downlink sensing (or information related to a downlink sensing reference signal) may be transmitted including configuration information for downlink sensing of UE B. For example, the configuration information for downlink sensing of the UE B may include RNTI information related to the UE B or resource information for receiving a downlink sensing reference signal of the UE B. For example, the UE B that receives the configuration information for downlink sensing (or information related to the downlink sensing reference signal) from the base station may know that it is a UE that receives a downlink sensing reference signal and may monitor the downlink sensing reference signal transmitted from the sensing area.For example, when the UE B receives a downlink sensing reference signal transmitted from the sensing area, the UE B can perform sensing for the sensing area based on the received downlink sensing reference signal (the downlink sensing reference signal received by a specific UE in FIG. 9), and transmit / report the sensing measurement result for the sensing area to the base station or the sensing management function (SMF) (or, sensing function (SF)).

[0192] In addition, for example, UE A, which is a neighboring UE of UE B configured to perform sensing by the base station (or UE A, which is a UE located around UE B), can also receive the configuration information for the downlink sensing (or information related to the downlink sensing reference signal) transmitted (or broadcasted) by the base station. For example, UE A can know that UE B, not UE A itself, is the UE receiving the downlink sensing reference signal based on the received configuration information for the downlink sensing (or information related to the downlink sensing reference signal). In this case, for example, when a certain condition is satisfied in the relationship with UE B, not only UE B but also UE A can receive (or overhear) the downlink sensing reference signal transmitted from the sensing area. For example, if the "certain condition" relates to a "sensing service", and the sensing service that UE A is interested in is the same as the sensing service that UE B is interested in, not only UE B but also UE A can receive (or overhear) a downlink sensing reference signal transmitted from the sensing area. For example, UE A can also perform sensing for the sensing area based on the received downlink sensing reference signal (the overheard downlink sensing reference signal of FIG. 9) and transmit / report the sensing measurement result for the sensing area to the base station (or SMF (sensing management function)). Or, for example, if the "certain condition" relates to an "area", and if the area that UE A includes is the same as the area that UE B includes, not only UE B but also UE A can receive (or overhear) a downlink sensing reference signal transmitted from the sensing area.For example, the UE A may also perform sensing for the sensing area based on the received downlink sensing reference signal (the overheard downlink sensing reference signal of FIG. 9), and transmit / report the sensing measurement result for the sensing area to the base station (or, sensing management function (SMF)). In this case, for example, the UE A may transmit / report the sensing measurement result together with identification information (e.g., UE A's own location information, etc.) indicating that its sensing result was generated based on the overheard downlink sensing reference signal.

[0193] In addition, for example, the base station can receive sensing measurement results for the sensing area from the UE B, as well as sensing measurement results for the sensing area from the UE A that overhears the downlink sensing reference signal, so that the base station can perform multi-static sensing.

[0194] FIG. 10 illustrates a method for overhearing an uplink sensing reference signal according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0195] Referring to FIG. 10, in order to perform bi-static sensing for a sensing region (or a target sensing region), a base station may transmit configuration information for uplink sensing (or information related to an uplink sensing reference signal). Or, for example, the base station may broadcast system information for sensing (e.g., a system information block (SIB)) via RRC. For example, the base station may transmit the configuration information for uplink sensing (or information related to an uplink sensing reference signal) including information specifying a UE that will transmit an uplink sensing reference signal in order to perform sensing for the sensing region (or the target sensing region). For example, when the base station specifies UE B as a UE that transmits an uplink sensing reference signal, the configuration information for uplink sensing (or information related to an uplink sensing reference signal) may be transmitted including configuration information for uplink sensing of UE B. For example, the configuration information for uplink sensing of the UE B may include RNTI information related to the UE B or resource information for transmission of an uplink sensing reference signal of the UE B.

[0196] For example, UE B, which receives configuration information for uplink sensing (or information related to an uplink sensing reference signal) from the base station, can recognize that it is a UE transmitting an uplink sensing reference signal and can transmit the uplink sensing reference signal to the sensing area. For example, when the base station receives an uplink sensing reference signal transmitted from the sensing area, the base station can perform sensing for the sensing area based on the received uplink sensing reference signal (uplink sensing reference signal received by the base station in FIG. 10).

[0197] In addition, for example, UE A, which is a neighboring UE of UE B configured to transmit an uplink sensing reference signal by the base station (or UE A, which is a UE located around UE B), can also receive configuration information for uplink sensing (or information related to an uplink sensing reference signal) transmitted (or broadcast) by the base station. For example, UE A can know that a base station, not UE A itself, is the entity that receives the uplink sensing reference signal based on the received configuration information for uplink sensing (or information related to an uplink sensing reference signal). In this case, for example, when a certain condition is satisfied in the relationship between UE A and UE B, not only the base station but also the UE A can receive (or overhear) the uplink sensing reference signal transmitted by UE B. For example, if the "certain condition" relates to a "sensing service", and the sensing service that UE A is interested in is the same as the sensing service that UE B is interested in, not only the base station but also the UE A can receive (or overhear) an uplink sensing reference signal transmitted from the sensing area. For example, the UE A can also perform sensing for the sensing area based on the received uplink sensing reference signal (the overheard downlink sensing reference signal of FIG. 10) and transmit / report the sensing measurement result for the sensing area to the UE B or the base station (or a sensing management function (SMF)). Or, for example, if the "certain condition" relates to an "area", and the area that UE A includes is the same as the area that UE B includes, not only the base station but also the UE A can receive (or overhear) an uplink sensing reference signal transmitted from the sensing area.For example, the UE A may also perform sensing for the sensing area based on the received uplink sensing reference signal (the overheard uplink sensing reference signal of FIG. 10), and transmit / report the sensing measurement result for the sensing area to the UE B or the base station (or, sensing management function (SMF)). In this case, for example, the UE A may transmit / report the sensing measurement result together with identification information (e.g., UE A's own location information, etc.) indicating that its sensing result was generated based on the overheard uplink sensing reference signal.

[0198] FIG. 11 illustrates a method for overhearing a sensing reference signal according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0199] Referring to FIG. 11, in step S1110, UE A can obtain configuration information for sensing transmitted from a base station. For example, the configuration information for sensing may include information related to a sensing reference signal (e.g., RNTI information related to a UE receiving a sensing reference signal or resource information for transmitting and receiving a sensing reference signal). For example, even if the base station transmits the configuration information for sensing to UE B rather than UE A, if UE A is also included in an area including UE B or if UE A is interested in the same sensing service as the sensing service of interest of UE B, UE A may also be determined to be a UE that is allowed to receive (overhear) a sensing reference signal for UE B. In step S1120, the UE B set as the target UE by the base station can not only receive the sensing reference signal transmitted from the target sensing area, but also the UE A can receive (overhear) the sensing reference signal transmitted from the target sensing area based on the configuration information for sensing of the UE B. For example, if the UE A determines that it is also a UE that is allowed to receive (overhear) the sensing reference signal for the UE B, as in the above-described step S1110, the UE A can receive (overhear) the sensing reference signal transmitted from the target sensing area. In step S1130, the UE A can perform sensing for the sensing area based on the overheard sensing reference signal (for example, the UE B can also perform sensing for the sensing area based on the received sensing reference signal). In step S1140, the UE B can report to the base station the sensing result for the target sensing area measured based on the received sensing reference signal, and the UE A can also report to the base station the sensing result for the target sensing area measured based on the overheard sensing reference signal.In this case, for example, UE A may transmit / report the sensing measurement result together with identification information (e.g., UE A's own location information, etc.) indicating that its sensing result was generated based on an overhearing sensing reference signal.

[0200] Meanwhile, for example, in ISAC, efficient resource management may be required to satisfy the performance or QoS requirements for both sensing and communication functions using limited bandwidth or resources. For example, if a large amount of bandwidth is allocated to the communication function, the bandwidth for the sensing function may be insufficient, and conversely, if a large amount of bandwidth is allocated to the sensing function, the bandwidth for the communication function may be insufficient.

[0201] Therefore, in the present disclosure, we propose the following operation for allocating resources for a UE according to the amount of function (sensing and communication) activity.

[0202] For example, the UE may transmit auxiliary information for sensing activity or communication activity to the base station. For example, the base station may manage radio resources (e.g., sensing resources and communication resources) based on auxiliary information received from the UE (e.g., buffer status of sensing activity: e.g., buffer status for sensing RS transmission, or buffer status of communication activity: buffer status for communication data / communication signal). For example, in the case of an ISAC signal in which a sensing signal is embedded in a communication signal, the base station and the TRP can allocate fewer symbols for the sensing signal to the terminal than for the communication signal based on the auxiliary information reported by the terminal if there are many communication activity reports, or can allocate more symbol resources for the sensing signal (compared to the communication signal) to the terminal if there are few communication activity reports and many sensing activity reports (e.g., this does not mean that there are more symbols for the sensing signal than for the communication signal).

[0203] As described above, in the present disclosure, terminal operations for ISAC sensing RS transmission and ISAC sensing RS reception are proposed.

[0204] FIG. 12 illustrates a method for a first device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0205] Referring to FIG. 12, in step S1210, the first device can obtain configuration information for a second device that transmits or receives a first sensing reference signal. In step S1220, the first device can receive the first sensing reference signal based on the configuration information for the second device. In step S1230, the first device can perform sensing for a target sensing area related to the first sensing reference signal.

[0206] For example, based on information related to resources included in the configuration information for the second device, the first sensing reference signal can be received by the first device.

[0207] For example, based on information related to resources included in the configuration information for the second device, the first sensing reference signal can be received by the first device.

[0208] For example, based on the sensing service that the first device is interested in being the same as the sensing service that the second device is interested in, the first device can receive the first sensing reference signal based on the configuration information for the second device.

[0209] For example, based on the area including the first device being the same as the area including the second device, the first device can receive the first sensing reference signal based on the setting information for the second device.

[0210] Additionally, for example, the first device may transmit information related to a sensing result for the target sensing area measured based on the first sensing reference signal to the base station based on the base station transmitting the first sensing reference signal. For example, the information related to the sensing result may include identification information indicating that the first sensing reference signal is a sensing reference signal for the second device.

[0211] Additionally, for example, the first device may transmit information related to a sensing result for the target sensing area measured based on the first sensing reference signal to the second device based on the second device transmitting the first sensing reference signal. For example, the information related to the sensing result may include identification information indicating that the first sensing reference signal is a sensing reference signal for a base station.

[0212] Additionally, for example, the first device can report information related to a sensing result for the target sensing region measured based on the first sensing reference signal. For example, the information related to the sensing result can include location information of the first device for estimating information related to the target sensing region. For example, whether the information related to the sensing result is to be used for the purpose of multi-static sensing or for the purpose of environment sensing for a plurality of target sensing regions including the target sensing region can be determined based on the location information of the first device.

[0213] Additionally, for example, based on the first device obtaining configuration information for the second device from the base station, the first device may request the base station for resources to report sensing results for the target sensing area measured based on the first sensing reference signal.

[0214] For example, based on information related to the target sensing area, resources for transmitting or receiving the first sensing reference signal can be set.

[0215] Additionally, for example, the first device may obtain information on a plurality of candidate resources associated with at least one sensing reference signal. Furthermore, for example, the first device may measure interference for each of the plurality of candidate resources. For example, the first device may select a resource for receiving the first sensing reference signal from among the plurality of candidate resources based on the interference-related information. Furthermore, for example, information related to the selected resource may be transmitted to a base station.

[0216] For example, information for releasing a resource associated with the second sensing reference signal may be received by the first device based on the second device failing to transmit the second sensing reference signal after transmitting the first sensing reference signal.

[0217] The proposed method can be applied to devices according to various embodiments of the present disclosure. First, the processor (102) of the first device (100) can control the transceiver (106) to obtain configuration information for a second device that transmits or receives a first sensing reference signal. Then, the processor (102) of the first device (100) can control the transceiver (106) to receive the first sensing reference signal based on the configuration information for the second device. Then, the processor (102) of the first device (100) can perform sensing for a target sensing area related to the first sensing reference signal.

[0218] According to one embodiment of the present disclosure, a first device configured to perform wireless communication may be provided. For example, the first 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, the instructions, when executed, may cause a first device to: obtain configuration information for a second device that transmits or receives a first sensing reference signal; receive the first sensing reference signal based on the configuration information for the second device; and perform sensing for a target sensing area associated with the first sensing reference signal.

[0221] FIG. 13 illustrates a method for a second device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 13 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0222] Referring to FIG. 13, in step S1310, the second device can transmit setting information for a third device that performs sensing for a target sensing area to the third device. In step S1320, the second device can transmit a first sensing reference signal to the target sensing area. In step S1330, the second device can receive a sensing result for the target sensing area from the first device. For example, the sensing result may be a sensing result measured based on the first sensing reference signal received by the first device based on the setting information for the third device.

[0223] The proposed method can be applied to devices according to various embodiments of the present disclosure. First, the processor (202) of the second device (200) can control the transceiver (206) to transmit setting information for a third device that performs sensing for a target sensing area to the third device. Then, the processor (202) of the second device (200) can control the transceiver (206) to transmit a first sensing reference signal to the target sensing area. Then, the processor (202) of the second device (200) can control the transceiver (206) to receive a sensing result for the target sensing area from the first device. For example, the sensing result can be a sensing result measured based on the first sensing reference signal received by the first device based on the setting information for the third device.

[0224] 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, the instructions, based on execution by the at least one processor, may cause the second device to: transmit configuration information for a third device performing sensing for a target sensing region to the third device; transmit a first sensing reference signal to the target sensing region; and receive a sensing result for the target sensing region from the first device. For example, the sensing result may be a sensing result measured based on the first sensing reference signal received by the first device based on the configuration information for the third device.

[0225] 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, the instructions, based on execution by the at least one processor, may cause the second device to: transmit configuration information for a third device performing sensing of a target sensing region to the third device; transmit a first sensing reference signal to the target sensing region; and receive a sensing result for the target sensing region from the first device. For example, the sensing result may be a sensing result measured based on the first sensing reference signal received by the first device based on the configuration information for the third device.

[0226] According to one embodiment of the present disclosure, a non-transitory computer-readable storage medium having instructions recorded thereon may be provided. For example, the instructions, when executed, may cause a second device to: transmit configuration information for a third device performing sensing of a target sensing region to the third device; transmit a first sensing reference signal to the target sensing region; and receive a sensing result for the target sensing region from the first device. For example, the sensing result may be a sensing result measured based on the first sensing reference signal received by the first device based on the configuration information for the third device.

[0227] According to various embodiments of the present disclosure, a neighboring UE of a specific UE determined / configured by a base station as a UE performing transmission / reception of a sensing RS (e.g., an uplink sensing RS or a downlink sensing RS) may overhear a sensing RS (uplink sensing RS) transmitted by the specific UE or a sensing RS (downlink sensing RS) transmitted by the base station for the specific UE, even if the neighboring UE is not determined / configured by the base station as a UE performing transmission / reception of the sensing RS. Specifically, for example, due to the mobility of a specific UE determined / set by a base station (or, if the target sensing area is based on a specific cluster, due to the mobility of the specific cluster), even if the distance between the specific UE and the target sensing area exceeds a threshold or the line of sight (LOS) between the specific UE and the target sensing area is not secured, a neighboring UE of the specific UE can receive (e.g., overhear) a sensing RS for the specific UE. In this case, for example, if the neighboring UE is in an environment advantageous for receiving the sensing RS for the specific UE, the reception quality related to the sensing RS received by the neighboring UE can be guaranteed, and the reliability / accuracy of sensing for the target sensing area measured by the neighboring UE based on the sensing RS received and / or the reliability / accuracy of the measurement result can be increased. Alternatively, for example, the quality of a sensing service related to the sensing RS can be improved because the sensing result measured based on the sensing RS received by the specific UE can be additionally used in addition to the sensing result measured based on the sensing RS overheard by the neighboring UE.Alternatively, for example, neighboring UEs other than the specific UE determined / configured by the base station may also receive the sensing RS, thereby improving the efficiency of resource utilization for sensing in the target sensing area. Alternatively, for example, by allowing neighboring UEs around the specific UE other than the specific UE determined / configured by the base station to receive the sensing RS (e.g., overhearing), the sensing range associated with the sensing RS may be expanded.

[0245] Fig. 16 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of Fig. 16 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.

[0246] Referring to FIG. 16, 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. 16 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 15. The hardware elements of FIG. 16 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 15. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 15. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 15, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 15.

[0247] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 16. 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).

[0248] 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.

[0249] 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.

[0250] 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. 16. For example, a wireless device (e.g., 100, 200 of FIG. 15) 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.
