[0041] 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.

[0042] 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).

[0043] 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.

[0044] 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).

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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).

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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).

[0056] 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.

[0057] 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).

[0058] 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).

[0059] 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.

[0060] 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

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. For example, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a crucial role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. AI can also facilitate rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0073] - 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.

[0091] - 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] 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.

[0093] 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.

[0094] Below, the integrated sensing and communication (ISAC) mentioned above is described in detail.

[0095] 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. 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. 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 sensing transmitter (e.g., bistatic sensing).

[0144] Meanwhile, in the prior art, in order to support a sensing service, a Tx UE can transmit a sensing RS (reference signal) to a target sensing area, and if the Tx UE can perform a beam-based operation, the sensing RS can be transmitted through the beam. However, in the prior art, when the Tx UE supports multiple sensing services, a specific operation for transmitting each sensing RS related to the multiple sensing services is not defined. In this case, the following problems may occur. For example, when the Tx UE transmits each sensing RS to each target sensing area related to the multiple sensing services, resource management operations or scheduling operations for transmitting each sensing RS may be performed separately, which may reduce the efficiency of resource use. In this case, for example, more time / frequency resources may be consumed to separately transmit different sensing RSs. Or, for example, transmitting each sensing RS separately may reduce the resources available for transmitting data, etc. In addition, for example, even when each target sensing area overlaps with another, the operation of transmitting the sensing RS may be performed repeatedly / independently without considering this. In this case, for example, the latency associated with the transmission of multiple sensing RSs may increase. Or, for example, since the transmission for each sensing RS is performed individually, the power of the terminal may be unnecessarily consumed. In particular, for example, if the Tx UE can perform beam-based operation, the Tx UE may individually transmit the multiple sensing RSs through the beam set for each of the multiple sensing RSs, which may further aggravate the above-described problems.

[0145] Accordingly, in the present disclosure, a method for transmitting a sensing RS for each of a plurality of sensing services and a device supporting the same are proposed.

[0146] In addition, in conventional communications (e.g., NR Uu or NR 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., 1. sensing latency: the time taken from when a terminal triggering sensing triggers the sensing procedure to when the sensing result of the target object is received from the receiving terminal, 2. sensing accuracy, etc.).

[0147] Therefore, in the present disclosure, the sensing behavior of a device (e.g., a terminal, a base station, or a sensing management function (SMF)) in ISAC is regarded as a service that must satisfy ISAC sensing QoS requirements, and the device behavior based on the sensing QoS is proposed as follows.

[0148] [Proposal #1] Defining QoS profiles or QoS flows for sensing in ISAC

[0149] In this disclosure, we propose an operation in which sensing in ISAC is regarded as a higher layer service that must satisfy sensing QoS (or sensing quality) based on the sensing results, as follows. In addition, a new QoS (e.g., SQFI) for the ISAC sensing service can be defined as follows.

[0150] - Yes, SQFI (sensing QoS flow ID)

[0151] - SQFI 1~8 (differentiated by the level of sensing QoS requirements (e.g., 1. sensing accuracy, 2. sensing latency: e.g., latency boundary from sensing triggering to receiving sensing results, 3. sensing priority: e.g., 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 SQFI value, the 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.

[0152] For example, a higher layer (e.g., a V2X layer or an application layer or a sensing layer or a sensing protocol, etc., if the device triggering the sensing procedure is a V2X terminal) of a device (e.g., a terminal or a base station or an SMF) can trigger an AS (access stratum) layer (e.g., a MAC layer and / or an RRC layer and / or a PHY layer, etc.) to perform a sensing operation when a certain condition is satisfied and a sensing service is triggered. In this case, for example, when the upper layer of the device triggers a sensing procedure to the AS layer, the sensing triggering indication primitive may be transmitted together with a sensing service QoS profile or a sensing service QoS flow ID (e.g., SQFI), so that the device performing the sensing may perform a sensing operation (e.g., a procedure for receiving a sensing result from a sensing RS (reference signal) transmitting device or a sensing RS receiving device within a latency budget) so as to satisfy the QoS requirements of the sensing (e.g., the QoS requirements of the sensing service QoS profile or the QoS requirements mapped to the sensing service QoS flow ID). For example, if the device that triggers sensing is not a terminal but an external network entity (e.g., SMF), when the SMF transmits a sensing trigger message to the device that performs sensing (e.g., a sensing RS transmitting device), the sensing trigger message may include sensing service QoS requirements (e.g., QoS requirements of a sensing service QoS profile, or QoS requirements mapped to a sensing service QoS flow ID) and transmit the message.For example, a device that receives a sensing message and sensing service QoS requirements from an SMF can perform a sensing operation (e.g., a procedure for receiving a sensing result from a sensing RS (reference signal) transmitting device or a sensing RS receiving device within a latency budget) so as to satisfy the QoS requirements of the sensing (e.g., a QoS requirement of a sensing service QoS profile or a QoS requirement mapped to a sensing service QoS flow ID).

[0153] [Proposal #2] A method for multiplexing a sensing RS and a communication signal (e.g., a control signal or a data signal) based on an SQFI (e.g., a sensing service QoS identifier) ​​in an ISAC.

[0154] For example, a device may transmit multiple RSs for multiple sensing services. In this case, if the device has a communication signal (e.g., a control signal or a data signal) to transmit to a destination device (e.g., a receiving device), the multiple RSs and the communication signal may be multiplexed. In the present disclosure, when a single device transmits multiple sensing RSs, a method of multiplexing them with an SQFI-based communication signal is proposed as follows.

[0155] For example, a device that transmits multiple sensing RSs (e.g., a device that transmits sensing RSs by triggering a sensing procedure by itself, or a device that transmits sensing RSs by requesting / triggering a sensing procedure from a counterpart device) may transmit sensing RSs associated with each sensing service by multiplexing them with a communication signal, wherein the SQFI associated with each sensing service is the same. For example, the SQFI may be transmitted in the form of "Sensing RS" + "Sensing RS" + "Sensing RS" + "Control signal (e.g., PSCCH)", or "Sensing RS" + "Sensing RS" + "Sensing RS" + "Control signal (e.g., PSCCH) + Data signal (e.g., PSSCH)". In addition, for example, the device may transmit multiple sensing RSs by multiplexing them with a communication signal, regardless of the QoS requirements of the sensing service (e.g., SQFI). In addition, for example, when a device transmits multiple sensing RSs by multiplexing them with a communication signal, the transmission power must be shared among the multiple RS transmissions, which may reduce the gain in terms of transmission power. Therefore, when multiple sensing RSs can be multiplexed with a communication signal, the sensing RS transmission device and the receiving device and / or scatterers that receive the sensing RSs and collect the sensing results may be applied only when the distance between them is below a certain distance threshold (e.g., a preset threshold, or a threshold set from a base station). For example, the certain distance threshold may be determined based on the zone ID information of the Rx entity (e.g., the sensing receiver).Alternatively, for example, the predetermined distance threshold may be limited to a case where the Tx entity (e.g., sensing transmitter) / Rx entity (e.g., sensing receiver) have the same zone ID (e.g., an identifier that distinguishes the region where the sensing transmitter and / or sensing receiver are located). Alternatively, for example, the predetermined distance threshold may be limited to a case where the difference in zone ID values ​​for the regions where the Tx entity (e.g., sensing transmitter) / Rx entity (e.g., sensing receiver) are located is less than or equal to a threshold.

[0156] [Proposal #3] A method for multiplexing sensing RSs based on sensing modes (e.g., monostatic sensing or bistatic sensing) in ISAC.

[0157] For example, ISAC sensing can support a sensing mode using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing) (see (a) of FIG. 8) and a sensing mode using separate sensing receivers and sensing transmitters (e.g., bistatic sensing) (see (b) of FIG. 8). For example, from the perspective of a sensing transmitter transmitting a sensing RS, a destination (e.g., sensing receiver) ID in monostatic sensing and a destination (e.g., sensing receiver) ID in bistatic sensing can be different from each other. In the above-described proposal #2 of the present disclosure, an operation of multiplexing a plurality of sensing RSs is proposed. In the present disclosure, in the case where a sensing transmitter has multiple sensing RSs to transmit according to a sensing service, the following operation is proposed to allow multiplexing only between RSs of the same sensing mode (e.g., monostatic sensing or bistatic sensing), so that the sensing RSs can be transmitted through a single common communication signal.

[0158] For example, when multiple sensing RSs for monostatic sensing are multiplexed onto a common communication signal, the sensing transmitter can transmit the sensing RSs with the following ID settings. For example, a field indicating a source ID and a destination ID for the sensing RSs and a field indicating a source ID and a destination ID for the communication data can be independently defined in a communication control message (e.g., a control message via a physical control channel) for transmitting communication data (e.g., data transmission via a physical shared channel) so that the source ID / destination ID of each (e.g., the sensing RSs and the communication data) can be independently indicated. For example, in the case of monostatic sensing, the source ID field and the destination ID field can indicate the same ID value (e.g., the source ID). Also, for example, when using a common field as an ID field for sensing RS and communication data, the destination ID of the monostatic sensing RS can be indicated with the same ID value as the source ID. For example, when indicating the source ID and the destination ID with the same ID, the (full) source ID can be reconstructed by concatenating the source ID and the destination ID. Or, for example, the sensing transmitter can include an indicator flag (e.g., flag value "0" = monostatic sensing, or flag value "1" = bistatic sensing) in a control message (e.g., a control message transmitted over a physical shared channel) to distinguish whether the sensing RS is an RS for monostatic sensing or bistatic sensing.Alternatively, for example, in the case of monostatic sensing (e.g., flag = 0), the sensing transmitter may indicate only the source ID without the destination ID (or only the destination ID without the source ID) in the control message.

[0159] For example, when multiple sensing RSs for bistatic sensing are multiplexed onto a common communication signal, the sensing transmitter can transmit the sensing RSs through the following ID settings. For example, in a communication control message (e.g., a control message via a physical control channel) for transmitting communication data (e.g., data transmission via a physical shared channel), a field indicating a source ID and a destination ID for the sensing RSs and a field indicating a source ID and a destination ID for the communication data can be independently defined, so that the source ID / destination ID of each (e.g., the sensing RS and the communication data) can be independently indicated. In addition, for example, when a common field is used as an ID field for the sensing RS and the communication data, only the sensing RSs having the same destination ID as the destination ID of the communication data can be filtered, and the sensing RSs can be multiplexed onto a common communication signal and then transmitted.

[0160] [Proposal #4] A Multiplexing Operation Method of Sensing RSs Based on the Sensing Priority of ISAC Services

[0161] As another embodiment of the above-described proposal #2 and proposal #3, the sensing transmitter can transmit multiple sensing RSs for sensing services having the same "sensing priority (e.g., a parameter indicating the priority of sensing performance among QoS requirements of the sensing service)" by multiplexing them into one common signal (e.g., "sensing RS" + "sensing RS" + "sensing RS" + "control signal (e.g., PSCCH)", or "sensing RS" + "sensing RS" + "sensing RS" + "control signal (e.g., PSCCH) + data signal (e.g., PSSCH)").

[0162] [Proposal #5] A method for multiplexing sensing RSs based on overlapping of spatial filter (or transmission beam (Tx beam), or reception beam (Rx beam)) areas (or coverage) used for RS transmission of sensing services.

[0163] For example, when multiple sensing RSs related to different sensing services are multiplexed to a single common signal (e.g., a control signal or a data signal), overlapping of target sensing areas (or overlapping of spatial filter (or transmission beam, or reception beam) areas (or coverage) applied to the sensing RSs, or overlapping of reference signal (RS) areas (or coverage) used to determine transmission power of the sensing RSs) may be considered as a criterion for selecting the sensing RSs that can be multiplexed. For example, when multiple sensing RSs related to different sensing services are multiplexed onto a common wireless communication signal (e.g., a control signal or a data signal), sensing RSs related to sensing services with overlapping sensing regions (target sensing regions) can be multiplexed onto a common wireless signal (e.g., a control signal or a data signal). Or, for example, sensing RSs with overlapping spatial filter (or transmission beam, or reception beam) regions (or coverages) used for RS transmission of sensing services can be multiplexed onto a common wireless communication signal. Or, for example, sensing RSs with overlapping RS (reference signal) regions (or coverages) used for determining transmission power of sensing RSs can be multiplexed onto a common wireless communication signal (e.g., a control signal or a data signal).In addition, for example, if the multiplexing criteria of the proposal #5 above (e.g., whether the spatial filter (or transmission beam, or reception beam) area (or coverage) used for RS transmission of the sensing service overlaps, or whether the RS (reference signal) area (or coverage) used for determining the transmission power of the sensing RS overlaps) are not met, a gap symbol may be required between the different sensing RSs. For example, if the multiplexing criteria of the proposal #5 above are met, the sensing RSs can be multiplexed without a gap symbol between the sensing RSs.

[0164] The multiplexing operation described in proposals #2, #3, #4 and #5 of the present disclosure may be supported even when the common signal to be multiplexed (e.g., a signal for wireless communication (e.g., data transmission)) is data of a separate service other than the ISAC sensing service. However, the multiplexing operation of the sensing RSs may be allowed only when, for example, all common signals having a priority equal to or higher than the priority of the sensing service associated with the sensing RS can be multiplexed, and otherwise (e.g., when all common signals having a priority equal to or higher than the priority of the sensing service associated with the sensing RS cannot be multiplexed), only the common signals may be configured to be transmitted. For example, in the above-described case where multiplexing operation of sensing RSs on a common signal is allowed, the number of sensing RSs to be multiplexed in ascending (or descending) order of SQFI (sensing QoS flow ID) values ​​can be determined (e.g., pre-configuration, set by the base station, or set through negotiation between terminals).

[0165] The embodiments of FIGS. 9 to 12 below are specific embodiments related to the above-described proposal #5.

[0166] FIG. 9 illustrates a method for transmitting sensing RSs for each of a plurality of sensing services according to an embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure.

[0167] Referring to FIG. 9, in the case of bi-static sensing, a Tx UE providing a sensing service can transmit a sensing RS (reference signal) to a target sensing area (TSA), and an Rx UE receiving the sensing RS reflected from the TSA can perform sensing for the target sensing area based on the received sensing RS. For example, if a sensing procedure is triggered so that the Tx UE provides multiple sensing services (sensing service #1 and sensing service #2), the Tx UE can transmit sensing RS #1 to TSA #1 associated with sensing service #1, and transmit sensing RS #2 to TSA #2 associated with sensing service #2. For example, even if the sensing service #1 and the sensing service #2 are different sensing services, if the TSA #1 and the sensing service #2 related to the sensing service #1 overlap each other, according to the proposal #5 described above, the Tx UE can transmit the sensing RS #1 and the sensing RS #2 by multiplexing them on a resource related to at least one of a control channel or a shared channel (or, the sensing RS #1 and the sensing RS #2 can be transmitted by being mapped on a resource related to at least one of a control channel or a shared channel). In this case, for example, the sensing RS #1 and the sensing RS #2 can be multiplexed on a resource related to at least one of a control channel or a shared channel based on the overlapping area of ​​the TSA #1 and the TSA #2 being greater than or equal to a threshold value. For example, the sensing RS #1 and the sensing RS #2 multiplexed on resources associated with at least one of the control channel or the shared channel may be transmitted to the TSA #1 or the TSA #2.For example, the multiplexed sensing RS #1 and sensing RS #2 may be reflected from the TSA #1 or the TSA #2 and received by the Rx UE. For example, the Rx UE that receives the multiplexed sensing RS #1 and sensing RS #2 may perform sensing for the TSA #1 and / or the TSA #2 based on the sensing RS #1 and / or the sensing RS #2. For example, the Rx UE may transmit / report the sensing results for the sensing service #1 and / or the sensing service #2 obtained based on the sensing for the TSA #1 and / or the TSA #2 to the Tx UE.

[0168] Also, referring to FIG. 9, a beam (beam #1 with beam forming performed in the direction of TSA #1) for transmitting sensing RS #1 related to sensing service #1 and a beam (beam #2 with beam forming performed in the direction of TSA #2) for transmitting sensing RS #2 related to sensing service #2 may be set respectively, but when TSA #1 related to sensing service #1 and sensing service #2 overlap each other, beam #1 and beam #2 may also overlap each other. In this case, for example, if the sensing procedure is triggered so that the Tx UE provides multiple sensing services (sensing service #1 and sensing service #2), the Tx UE does not transmit each sensing RS through the beam set for each sensing RS (i.e., does not transmit sensing RS #1 through beam #1 and does not transmit sensing RS #2 through beam #2), but rather, the Tx UE can multiplex the sensing RS #1 and sensing RS #2 according to the proposal #5 described above, so that the multiplexed sensing RS #1 and sensing RS #2 can be transmitted together through either the beam #1 or the beam #2.

[0169] FIG. 10 illustrates a method for multiplexing multiple sensing RSs according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure.

[0170] Referring to FIG. 10, a Tx UE triggered to provide sensing service #1 and sensing service #2 may transmit sensing RS #1 associated with sensing service #1 and sensing RS #2 associated with sensing service #2 by multiplexing them with wireless communication signals (e.g., control signals and / or data signals) when TSA #1 associated with sensing service #1 and TSA #2 associated with sensing service #2 overlap. For example, FIG. 10 may illustrate an example of the multiplexed sensing RSs (sensing RS #1 and sensing RS #2) and wireless communication signals (e.g., control signals and / or data signals). For example, the sensing RS #1 may be mapped onto a time / frequency resource associated with a control channel or a time / frequency resource associated with a shared channel. And, for example, the sensing RS #2 can be mapped onto the time / frequency resources associated with the control channel or the time / frequency resources associated with the shared channel. In summary, when TSA #1, where the sensing RS #1 is transmitted, and TSA #2, where the sensing RS #2 is transmitted, overlap with each other, the sensing RS #1 and the sensing RS #2 can be multiplexed with a wireless communication signal (e.g., a control signal and / or a data signal) and transmitted together.

[0171] Also, referring to FIG. 10, when TSA #1 related to sensing service #1 and TSA #2 related to sensing service #2 overlap, sensing RS #1 transmitted to TSA #1 and sensing RS #2 transmitted to TSA #2 can be multiplexed without a gap (or gap symbol) between sensing RS #1 and sensing RS #2. For example, even if a beam for transmitting the sensing RS #1 and a beam for transmitting the sensing RS #2 are respectively set, if the sensing RS #1 and the sensing RS #2 are multiplexed without a gap (or gap symbol) between them, the Tx UE can perform transmission of the multiplexed sensing RS #1 and sensing RS #2 using only one of the beam for transmitting the sensing RS #1 and the beam for transmitting the sensing RS #2, without having to perform beam switching between the beam for transmitting the sensing RS #1 and the beam for transmitting the sensing RS #2. Hereinafter, related technologies will be described in detail in the embodiments of FIG. 11 and FIG. 12.

[0172] FIG. 11 illustrates a method for transmitting multiple sensing RSs when target sensing areas associated with each sensing service do not overlap, according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure.

[0173] Referring to FIG. 11, for an ISAC sensing service, a Tx UE may transmit a sensing RS based on a beam. For example, if the Tx UE is configured to provide multiple ISAC sensing services, the Tx UE may transmit a sensing RS for each of the multiple ISAC sensing services via a beam. For example, the multiple ISAC sensing services may be based on sensing for multiple different target sensing areas (TSAs). For example, if the multiple target sensing areas are TSA #1, TSA #2, and TSA #3, sensing RS #1 may be transmitted to TSA #1, sensing RS #2 may be transmitted to TSA #2, and sensing RS #3 may be transmitted to TSA #3. In this case, for example, beam #1 may be set for transmission of the sensing RS #1, beam #2 may be set for transmission of the sensing RS #2, and beam #3 may be set for transmission of the sensing RS #3. For example, when the plurality of sensing areas (TSA #1, TSA #2, TSA #3) do not overlap with each other, the sensing RSs (sensing RS #1, sensing RS #2, sensing RS #3) for each of the plurality of sensing areas may be transmitted in different directions. In this case, for example, the areas covered by the beams (beam #1, beam #2, beam #3) for transmission of the respective sensing RSs may not overlap with each other. For example, when a Tx UE transmits multiple sensing RSs (sensing RS #1, sensing RS #2, sensing RS #3) based on multiple non-overlapping beams (beam #1, beam #2, beam #3), a gap may need to be guaranteed for performing beam management operations such as beam forming or beam switching related to the multiple beams (beam #1, beam #2, beam #3).For example, when a Tx UE transmits sensing RS #1, sensing RS #2, and sensing RS #3 within one slot, as in the embodiment of FIG. 10 described above, sensing RS #1, sensing RS #2, and sensing RS #3 may be mapped onto time / frequency resources associated with a control channel or time / frequency resources associated with a shared channel. In this case, for example, the sensing RS #1, the sensing RS #2, and the sensing RS #3 may be multiplexed such that a gap (or gap symbol) is set between the sensing RS #1, the sensing RS #2, and the sensing RS #3. For example, the Tx UE can transmit sensing RS #1 to TSA #1 via beam #1 and then perform beam management (e.g., beam forming or beam switching) in the gap associated with beam #2 to transmit sensing RS #2. And, for example, the Tx UE can transmit sensing RS #2 to TSA #2 via beam #2 and then perform beam management (e.g., beam forming or beam switching) in the gap associated with beam #3 to transmit sensing RS #3. And, for example, the Tx UE can transmit sensing RS #3 to TSA #3 via beam #3.

[0174] FIG. 12 illustrates a method for transmitting multiple sensing RSs when target sensing areas associated with each sensing service overlap, according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.

[0175] Referring to FIG. 12, as in the embodiment of FIG. 11 described above, when the plurality of target sensing areas are TSA #1, TSA #2, and TSA #3, respectively, sensing RS #1 may be transmitted to TSA #1, sensing RS #2 may be transmitted to TSA #2, and sensing RS #3 may be transmitted to TSA #3. In this case, for example, beam #1 may be set for transmission of sensing RS #1, beam #2 may be set for transmission of sensing RS #2, and beam #3 may be set for transmission of sensing RS #3. Meanwhile, in FIG. 12, unlike the embodiment of FIG. 11 described above, the plurality of sensing areas (TSA #1, TSA #2, and TSA #3) may overlap each other. For example, when the plurality of sensing areas (TSA #1, TSA #2, TSA #3) overlap with each other, the sensing RSs (sensing RS #1, sensing RS #2, sensing RS #3) for each of the plurality of sensing areas can be transmitted in the same direction or in a direction within a specific threshold value. In this case, for example, the areas covered by the beams (beam #1, beam #2, beam #3) for transmission of the respective sensing RSs can overlap with each other. In this case, for example, beam #1 for transmission of the sensing RS #1 can also be used for transmission of the sensing RS #2 or the sensing RS #3. Or, for example, beam #2 for transmission of the sensing RS #2 can also be used for transmission of the sensing RS #1 or the sensing RS #3. Or, for example, beam #3 for transmission of the sensing RS #3 can also be used for transmission of the sensing RS #1 or the sensing RS #2.For example, if TSA #1, TSA #2, and TSA #3 all overlap (or, if the area where TSA #1, TSA #2, and TSA #3 overlap each other is greater than or equal to a threshold value), as shown in FIG. 12, sensing RS #1, sensing RS #2, and sensing RS #3 may be mapped onto time / frequency resources associated with a control channel or time / frequency resources associated with a shared channel. In this case, for example, the sensing RS #1, the sensing RS #2, and the sensing RS #3 may be multiplexed without a gap (or a gap symbol) between the sensing RS #1, the sensing RS #2, and the sensing RS #3. For example, the sensing RS #1, the sensing RS #2, and the sensing RS #3 multiplexed without the gap can be transmitted to the TSA #1 using only the beam #1. Meanwhile, the multiplexed sensing RS #1, the sensing RS #2, and the sensing RS #3 can be reflected by the TSA #1 and received by the Rx UE. For example, the Rx UE can perform sensing for TSA #1 based on the received sensing RS #1, perform sensing for TSA #2 based on the received sensing RS #2, or perform sensing for TSA #3 based on the received sensing RS #3.

[0176] [Proposal #6] A method for reporting sensing results

[0177] In the present disclosure, a sensing result reporting procedure based on a timer (e.g., a timer set to latency boundary) for each QoS requirement of a sensing service (e.g., a sensing latency boundary requirement of SQFI) is proposed as follows.

[0178] For example, the sensing transmitter can perform a sensing operation by setting the QoS requirement of each sensing service (e.g., the sensing latency boundary requirement of SQFI: the latency boundary from when sensing is triggered to when the sensing result is received) as the sensing reporting timer value. For example, when the sensing transmitter triggers a sensing procedure and transmits a sensing RS, the sensing reporting timer can be started by setting the sensing latency boundary of the sensing service related to the sensing RS. For example, the sensing transmitter can receive or monitor a sensing result reporting message from a sensing receiver until the sensing reporting timer expires. For example, if the sensing transmitter does not receive a sensing report message from the sensing receiver until the sensing reporting timer expires, the sensing transmitter may stop monitoring sensing reporting messages related to the corresponding sensing service (or for sensing RSs related to the corresponding sensing service). For example, when transmitting a sensing RS, the sensing transmitter may include a sensing latency boundary value related to the corresponding sensing service (or for sensing RSs related to the corresponding sensing service) in a control message transmitted together with the sensing RS and transmit the sensing latency boundary value to the sensing receiver.For example, when the sensing receiver receives a sensing RS and a control message, it can check a sensing latency boundary value related to the sensing service (or for the sensing RS related to the sensing service), set and operate a timer with the sensing latency boundary value from the time of receiving the sensing RS, and transmit a sensing result reporting message to the sensing transmitter before the timer (e.g., the sensing latency boundary) expires. In addition, for example, the sensing latency boundary value related to the sensing service (or for the sensing RS related to the sensing service) can be defined in advance for each QoS level (e.g., SQFI) of the sensing service. And, for example, when transmitting a sensing RS, the sensing transmitter can transmit a sensing service QoS level (e.g., SQFI) value related to the corresponding sensing service to the sensing receiver in a control message transmitted together with the sensing RS. For example, when the sensing receiver receives a sensing RS and a control message, the sensing receiver can check the QoS level (e.g., SQFI) value related to the corresponding sensing service and derive a latency boundary value related to sensing result reporting of the corresponding sensing service. For example, the sensing receiver can set and operate a timer with a sensing latency boundary value from the time of receiving the sensing RS, and can transmit a sensing result reporting message to the sensing transmitter before the timer (e.g., sensing latency boundary) expires.

[0179] For example, a sensing result reporting message transmitted by a sensing receiver can be transmitted to a sensing transmitter via a MAC CE or a physical signal. In this case, for example, the logical channel prioritization (LCP) priority of the sensing result reporting MAC CE can be set lower than the priority of a control message for link establishment and higher than the priority of general communication data.

[0180] For reference, the above LCP procedure may be as follows:

[0181] For example, when a terminal has multiple messages or data to transmit (e.g., MAC CEs or communication data or (PC5) RRC messages), the terminal can first generate a MAC PDU for a message (or data) 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 MAC CE with a higher priority can be multiplexed into the MAC PDU first to generate the MAC PDU.

[0182] In the present disclosure, as described above, a method is proposed for defining QoS for sensing in an ISAC, thereby performing a procedure for a base station and / or a terminal to satisfy sensing requirements based on sensing QoS.

[0192] In embodiments of the present disclosure, the transmission beam may be interpreted as being replaced by a spatial TX (transmission) filter or a spatial domain TX (transmission) filter.

[0193] In embodiments of the present disclosure, the reception beam may be interpreted as being replaced by a spatial RX (reception) filter or a spatial domain RX (reception) filter.

In an embodiment of the present disclosure, the fact that the spatial setting information (or beam information) for reception is the same may mean that the two different reception signals are in a QCL TypeD relationship and / or use the same spatial RX parameter.

[0200] FIG. 13 illustrates a method for a first 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.

[0201] Referring to FIG. 13, in step S1310, the first device may transmit at least one of a control channel and a shared channel. In step S1320, the first device may transmit a first sensing reference signal (RS) related to a first sensing service. In step S1330, the first device may transmit a second sensing RS related to a second sensing service. For example, based on the overlapping of a first target sensing region related to the first sensing service and a second target sensing region related to the second sensing service, the first sensing RS and the second sensing RS may be transmitted on a resource related to at least one of the control channel and the shared channel.

[0202] For example, the first sensing RS and the second sensing RS may be multiplexed on the resource associated with at least one of the control channel or the shared channel.

[0203] For example, the first sensing RS and the second sensing RS can be multiplexed without a gap between the first sensing RS and the second sensing RS.

[0204] For example, the first sensing RS and the second sensing RS multiplexed on the resource associated with at least one of the control channel or the shared channel can be transmitted without a time gap.

[0205] For example, the first sensing RS and the second sensing RS multiplexed without a gap on the resource associated with at least one of the control channel or the shared channel may be transmitted via a single beam. For example, the single beam may be either a first beam for transmission of the first sensing RS or a second beam for transmission of the second sensing RS.

[0206] For example, a timer for receiving a sensing result for the first target sensing area obtained based on the first sensing RS may be initiated based on transmission of the first sensing RS. For example, monitoring for receiving the sensing result for the first target sensing area may be performed until the timer expires. For example, the length of the timer may be determined based on information related to the quality of service (QoS) of the first sensing service.

[0207] For example, the length of a timer for transmitting the sensing result for the first target sensing area by the second device that received the control channel and the first sensing RS may be determined based on information related to the QoS of the first sensing service included in the control channel.

[0208] For example, based on the fact that information related to QoS of the first sensing service and information related to QoS of the second sensing service are the same, the first sensing RS and the second sensing RS may be multiplexed on the resource associated with at least one of the control channel or the shared channel.

[0209] For example, based on the second device receiving the first sensing RS and the second sensing RS being within a threshold distance from the first device, the first sensing RS and the second sensing RS may be multiplexed on the resource associated with at least one of the control channel or the shared channel.

[0210] For example, based on the priority associated with the first sensing service being the same as the priority associated with the second sensing service, the first sensing RS and the second sensing RS may be multiplexed on the resource associated with at least one of the control channel or the shared channel.

[0211] 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 transmit at least one of a control channel and a shared channel. Then, the processor (102) of the first device (100) can control the transceiver (106) to transmit a first sensing reference signal (RS) related to a first sensing service. Then, the processor (102) of the first device (100) can control the transceiver (106) to transmit a second sensing RS related to a second sensing service. For example, based on the overlapping of the first target sensing area associated with the first sensing service and the second target sensing area associated with the second sensing service, the first sensing RS and the second sensing RS may be transmitted on a resource associated with at least one of the control channel and the shared channel.

[0212] 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, based on execution by the at least one processor, may cause the first device to: transmit at least one of a control channel and a shared channel; transmit a first sensing reference signal (RS) associated with a first sensing service; and transmit a second sensing RS associated with a second sensing service. For example, based on an overlap between a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be transmitted on a resource associated with at least one of the control channel and the shared channel.

[0213] According to one embodiment of the present disclosure, a processing device configured to control a first device may be provided. For example, the processing device may include at least one processor; and at least one memory coupled 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 first device to: transmit at least one of a control channel or a shared channel; transmit a first sensing reference signal (RS) associated with a first sensing service; and transmit a second sensing RS associated with a second sensing service. For example, based on an overlap between a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be transmitted on a resource associated with at least one of the control channel or the shared channel.

[0214] 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 first device to: transmit at least one of a control channel and a shared channel; transmit a first sensing reference signal (RS) associated with a first sensing service; and transmit a second sensing RS associated with a second sensing service. For example, based on an overlap between a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be transmitted on a resource associated with at least one of the control channel and the shared channel.

[0215] FIG. 14 illustrates a method for a second device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 14 may be combined with various embodiments of the present disclosure.

[0216] Referring to FIG. 14, in step S1410, the second device may receive at least one of a control channel or a shared channel. In step S1420, the second device may receive a first sensing reference signal (RS) associated with a first sensing service. In step S1430, the second device may receive a second sensing RS associated with a second sensing service. For example, based on the overlapping of a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be received on a resource associated with at least one of the control channel or the shared channel.

[0217] 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 receive at least one of a control channel and a shared channel. Then, the processor (202) of the second device (200) can control the transceiver (206) to receive a first sensing reference signal (RS) related to a first sensing service. Then, the processor (202) of the second device (200) can control the transceiver (206) to receive a second sensing RS related to a second sensing service. For example, based on the overlapping of the first target sensing area associated with the first sensing service and the second target sensing area associated with the second sensing service, the first sensing RS and the second sensing RS may be received on a resource associated with at least one of the control channel or the shared channel.

[0218] 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 coupled 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: receive at least one of a control channel or a shared channel; receive a first sensing reference signal (RS) associated with a first sensing service; and receive a second sensing RS associated with a second sensing service. For example, based on an overlap between a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be received on a resource associated with at least one of the control channel or the shared channel.

[0219] 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 coupled 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: receive at least one of a control channel or a shared channel; receive a first sensing reference signal (RS) associated with a first sensing service; and receive a second sensing RS associated with a second sensing service. For example, based on an overlap between a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be received on a resource associated with at least one of the control channel or the shared channel.

[0220] 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: receive at least one of a control channel and a shared channel; receive a first sensing reference signal (RS) associated with a first sensing service; and receive a second sensing RS associated with a second sensing service. For example, based on an overlap between a first target sensing region associated with the first sensing service and a second target sensing region associated with the second sensing service, the first sensing RS and the second sensing RS may be received on a resource associated with at least one of the control channel and the shared channel.

[0221] According to various embodiments of the present disclosure, when a terminal supporting multiple sensing services transmits sensing RSs related to multiple sensing services, if target sensing areas for each of the multiple sensing services overlap, the multiple sensing RSs may be multiplexed and transmitted. In this case, for example, instead of individually transmitting the sensing RSs for each of the multiple sensing services, if the target sensing areas overlap, the sensing RSs may be multiplexed and transmitted together, thereby improving the efficiency of resource use. Specifically, for example, instead of individually transmitting the sensing RS #1 related to sensing service #1 to TSA #1 and the sensing RS #2 related to sensing service #2 to TSA #2, the sensing RS #1 and the sensing RS #2 may be multiplexed and only one transmission may be performed to either TSA #1 or TSA #2, thereby efficiently managing and scheduling resources for transmitting the sensing RSs. In addition, since, for example, sensing RS #1 and sensing RS #2 can be transmitted by performing a single transmission, the latency associated with the transmission of multiple sensing RSs can be reduced, and the efficiency of power usage can be improved. In particular, for example, when beam-based operation is supported, even if a transmission beam is set for each of multiple sensing RSs, if the target sensing areas overlap with each other, the sensing RSs can be multiplexed and transmitted through a single transmission beam, so that the efficiency of the resource usage described above can be further improved, the latency associated with the transmission of the multiple sensing RSs described above can be further reduced, and the efficiency of the power usage described above can be further improved.

[0239] FIG. 17 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 17 can be combined with various embodiments of the present disclosure.

[0240] Referring to FIG. 17, 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. 17 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 16. The hardware elements of FIG. 17 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 16. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 16. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 16, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 16.

[0241] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 17. 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).

[0242] 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.

[0243] 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.

[0244] 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. 17. For example, a wireless device (e.g., 100, 200 of FIG. 16) 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.
