[0044] 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.

[0045] 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).

[0046] 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.

[0047] 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).

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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).

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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).

[0059] 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.

[0060] 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).

[0061] 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).

[0062] 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.

[0063] 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

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] - 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.

[0076] - 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] - 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.

[0092] 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.

[0093] - Integrated sensing and communication (ISAC): Wireless sensing is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the characteristics of the environment and / or objects within the environment.

[0094] - 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.

[0095] FIG. 7 illustrates an example of a communication scenario based on a 6G system, according to an embodiment of the present disclosure. The embodiment of FIG. 7 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0096] 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.

[0097] For example, a terminal can obtain information about the environment and / or the characteristics of objects within the environment by using radio frequency sensing to determine the instantaneous linear velocity, angle, distance (range), etc. of an object. Since radio frequency sensing does not require a device to connect to the object through a network, it can provide a service 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 that provide, for example, intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, health and traffic management, and more. 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 wireless sensing services, e.g., sensing operations, may depend on the transmission, reflection, and scattering of wireless sensing signals. Therefore, wireless sensing offers an opportunity to enhance existing communication systems from a communications network to a wireless communication and sensing network.

[0098] FIG. 8 illustrates an example of a sensing operation according to an embodiment of the present disclosure. The embodiment of FIG. 8 can 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, (a) of FIG. 8 illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and (b) of FIG. 8 illustrates an example of sensing using a separated sensing receiver and sensing transmitter (e.g., bistatic sensing).

[0099] Referring to FIG. 8, a sensing transmitter can transmit a sensing signal for sensing one or more objects (and / or an environment around the objects). For example, the sensing signal can be a radio (frequency) signal defined to be transmittable by a base station / terminal. For example, a sensing receiver can receive a signal scattered / reflected by one or more objects (and / or an environment around the objects) from a sensing signal transmitted from the sensing transmitter. For example, in the sensing receiver, sensing data can be derived from the scattered / reflected signal, and a sensing result can be generated / obtained through processing the sensing data. Here, for example, the sensing result can include characteristic information (e.g., position, distance, speed, angle, etc.) about one or more objects (and / or an environment around the objects). For example, the sensing results generated / obtained in this way may be utilized for wireless sensing services (e.g., detection, tracking, etc. of objects and / or environments) or provided / disclosed to a trusted third party.

[0100] For example, a sensing transmitter may be a base station or terminal that transmits a sensing signal to be used for a sensing service to operate, and the sensing transmitter may be located in the same or different base station or terminal as a sensing receiver. For example, a sensing receiver may be a base station or terminal that receives a sensing signal to be used for a sensing service to operate, and the sensing receiver may be located in the same or different base station or terminal as a sensing transmitter. For example, a sensing target may be an object to be detected by deriving characteristics of an object in the environment from a sensing signal. For example, a background environment may be a background that is not a sensing target (e.g., clutter, environmental objects, etc.). For example, an environment object may be an object whose location is known other than a sensing target. For example, monostatic sensing may be sensing in which a sensing transmitter and a sensing receiver coexist in the same base station or terminal. For example, bistatic sensing may be sensing in which the sensing transmitter and the sensing receiver are located in different base stations or terminals. For example, multistatic sensing may be sensing in which there are multiple sensing transmitters and / or multiple sensing receivers for a (single) sensing target. For example, monostatic sensing, bistatic sensing, and / or multistatic sensing may be distinguished based on the angle between the sensing transmitter, the sensing target, and the sensing receiver. For example, if the angle between the sensing transmitter, the sensing target, and the sensing receiver is less than or equal to a threshold, it may be defined as monostatic sensing or semi-monostatic sensing. For example, if the angle between the sensing transmitter, the sensing target, and the sensing receiver is greater than or equal to a threshold, it may be defined as bistatic sensing or multistatic sensing.For example, the terminal may transmit a sensing signal over a wireless interface that can be used for sensing purposes. For example, the terminal may transmit a sensing signal over a 3GPP wireless interface that can be used for sensing purposes.

[0101] For example, the common framework of the ISAC channel model can be composed of target channel components and background channel components. For example, this can be obtained based on mathematical equation 1.

[0102]

[0103] Here, for example, target channel H target may include all [multipath] components affected by the sensing target. For example, background channel H Background may contain other [multipath] components that do not belong to the target channel.

[0104] For example, radar cross-section (RCS) may be a measure of how well a radar sensor can detect a target. Therefore, it is often referred to as an electromagnetic characteristic of the target. For example, a larger RCS may indicate that the target is more easily detectable. For example, in a radar sensor measurement, power may be transmitted toward the target, and the target may reflect some of the power back to the receiver. For example, the received power may be based on the RCS of the target, among other factors. For example, the received power may be proportional to the RCS. For example, the RCS of a target may be based on at least one of the frequency of the radar signal, the target material, the target shape, the target size, the direction of the incident and reflected waves relative to the target, the target movement, and / or the target illumination.

[0105] FIG. 9 illustrates the relationship between RCS, range (D), and power according to one embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0106] Referring to Figure 9, the RCS of a radar target may be a virtual area required to intercept the power density transmitted from the target. For example, the relevant radar mathematical formula may be defined as in Equation 2.

[0107]

[0108] Here, for example, P TX can be the transmitter power [W], and G TXcan be the gain of the transmitting antenna [dimensionless], D can be the distance between the equipment under test (EUT) and the target [m], and RCS can be the radar cross section [m 2 ] can be, P RX can be the power [W] received back by the EUT from the object, and A eff is the effective area of ​​the receiving antenna [m 2 ] can be. For example, A eff can be obtained based on mathematical formula 3.

[0109]

[0110] Here, for example, G RX can be the gain of the receiving antenna [dimensionless], λ can be the wavelength of the radio signal [m], λ = c / f, c can be the speed of light 299792458 [m / s], and f can be the frequency [Hz].

[0111] For example, if the transmitter and receiver are co-located and the same antenna is used for both transmission and reception (G TX = G RX = G), the related radar mathematical formula can be defined as in mathematical formula 4.

[0112]

[0113] Here, for example, P TX can be the transmitter power [W], G can be the gain of the transmitting antenna [dimensionless], D can be the distance between the equipment under test (EUT) and the target [m], and RCS can be the radar cross section [m 2 ] can be, P RX can be the power [W] received back by the EUT from the object.

[0114] Below, the integrated sensing and communication (ISAC) mentioned above is described in detail.

[0115] 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 wireless sensing services (e.g., sensing operations) may depend on the transmission, reflection, and scattering of wireless sensing signals. Therefore, wireless sensing offers an opportunity to enhance existing communication systems from a communication network to a wireless communication and sensing network.

[0163] - SL PRS CCH: SL PRS control channel. Can signal SL PRS resource configuration information and resource location, etc.

[0164] For example, a UE (e.g., a MAC entity) may be configured with discontinuous reception (DRX) functionality to control the UE's PDCCH monitoring activity for the C-RNTI, CI-RNTI, CS-RNTI, INT-RNTI, SFI-RNTI, SP-CSI-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, TPC-SRS-RNTI and / or AI-RNTI of the UE (e.g., the MAC entity) by RRC. For example, when using discontinuous reception operation, the UE (e.g., the MAC entity) may also need to monitor the PDCCH according to the requirements of discontinuous reception. For example, when discontinuous reception is configured in RRC_CONNECTED, the UE (e.g., the MAC entity) may use discontinuous reception operation to discontinuously monitor the PDCCH for all activated serving cells. Otherwise, the terminal (e.g., MAC entity) may need to monitor the PDCCH. For example, if sidelink resource allocation mode 1 is configured by RRC, the discontinuous reception function may not be configured.

[0165] For example, RRC can control discontinuous reception operation by configuring the following parameters. For example, drx-onDurationTimer can mean the duration at the start of a discontinuous reception period. For example, drx-SlotOffset can mean the delay time before starting drx-onDurationTimer. For example, drx-InactivityTimer can mean the period after PDCCH occurrence indicating a new uplink or downlink transmission to a UE (e.g., MAC entity). For example, drx-RetransmissionTimerDL (per downlink HARQ process excluding broadcast process) can mean the maximum period until receiving a downlink retransmission. For example, drx-RetransmissionTimerUL (per uplink HARQ process) can mean the maximum period until receiving a grant for an uplink retransmission. For example, drx-LongCycleStartOffset may mean drx-StartOffset, which defines the subframe where a long discontinuous receive cycle and a long discontinuous receive cycle and a short discontinuous receive cycle start. For example, drx-ShortCycle may mean a short discontinuous receive cycle, and may be optional. For example, drx-ShortCycleTimer may mean a period of time for which the UE should follow a short discontinuous receive cycle, and may be optional. For example, drx-HARQ-RTT-TimerDL (per downlink HARQ process excluding broadcast process) may mean a minimum period of time before a downlink allocation for a HARQ retransmission that the UE (e.g., MAC entity) expects. For example, drx-HARQ-RTT-TimerUL (per uplink HARQ process) may mean the minimum period before an uplink HARQ retransmission grant that a terminal (e.g., a MAC entity) expects.

[0166] For example, the serving cell of a terminal (e.g., a MAC entity) may be configured into two discontinuous reception groups using separate discontinuous reception parameters by RRC. For example, if RRC does not configure an auxiliary discontinuous reception group, there may be only one discontinuous reception group, and all serving cells may belong to that discontinuous reception group. For example, if two discontinuous reception groups are configured, each serving cell may be uniquely assigned to one of the two groups. For example, the discontinuous reception parameters configured separately for each discontinuous reception group may include drx-onDurationTimer and / or drx-InactivityTimer. Additionally, for example, discontinuous reception parameters common to the discontinuous reception group may include drx-SlotOffset, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, drx-LongCycleStartOffset, drx-ShortCycle (optional), drx-ShortCycleTimer (optional), drx-HARQ-RTT-TimerDL and / or drx-HARQ-RTT-TimerUL.

[0167] For example, when a discontinuous reception cycle is configured, the active time for serving cells of a discontinuous reception group may include the time that drx-onDurationTimer or drx-InactivityTimer configured for the discontinuous reception group is running; the time that drx-RetransmissionTimerDL or drx-RetransmissionTimerUL is running on all serving cells of the discontinuous reception group; the time that ra-ContentionResolutionTimer or msgB-ResponseWindow is running; the time that a scheduling request is transmitted on PUCCH and is pending; and / or the time that a PDCCH indicating a new transmission addressed to the C-RNTI of the terminal (e.g., MAC entity) is not received after successfully receiving a random access response to a random access preamble that is not selected from among the contention-based random access preambles by the terminal (e.g., MAC entity).

[0168] For example, the terminal may perform the LCP procedure according to the LCP (Logical Channel Prioritization) priority order when there is logical channel data and / or MAC CE and / or control message (e.g., PC5-S message and / or PC5 RRC message) to transmit.

[0169] 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 priorities (e.g., priority). For example, when the terminal has 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., priority) 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 to generate a MAC PDU by preferentially selecting a message with a higher priority.

[0170] Meanwhile, 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 it takes for a terminal that triggers sensing to trigger the sensing procedure and receive the sensing result of the target object from a receiving terminal and / or 2. sensing accuracy, etc.). For example, in ISAC, the sensing behavior of a device (e.g., a terminal or a base station or a Sensing Management Function (SMF)) can be considered a service that must satisfy the ISAC sensing QoS requirement. For example, a terminal can perform sensing operations based on the corresponding sensing QoS (e.g., transmitting sensing RS and / or receiving sensing RS (sensing signal)). In addition, for example, in a sensing service, since sensing is performed for a target sensing area (TSA), it is necessary to perform sensing-related operations based on the target sensing area in order to perform sensing efficiently.

[0171] In the present disclosure, for example, sensing in ISAC can be considered as a higher layer service that must satisfy sensing QoS (or sensing quality) based on the sensing results. Furthermore, for example, a new QoS (e.g., SQFI) for the ISAC sensing service can be defined as follows.

[0172] - For example, the sensing QoS flow ID (SQFI) can be:

[0173] - SQFI 1~8 (can be distinguished 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, and / or 3. 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 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.

[0174] In this disclosure, a power saving operation for sensing RS (sensing signal) reception and sensing RS (sensing signal) transmission of a UE in ISAC is proposed.

[0175] For example, a UE supporting discontinuous reception (DRX) operation may use a data communication discontinuous reception configuration to monitor and receive ISAC sensing RS (sensing signals) transmitted by a base station, and / or may perform discontinuous reception operation using, for example, a dedicated discontinuous reception configuration for ISAC sensing RS (sensing signals) monitoring.

[0176] Hereinafter, enhancements to conventional data communication discontinuous reception settings for ISAC sensing RS (sensing signal) monitoring according to various embodiments are described.

[0177] In the present disclosure, a power saving (or discontinuous reception (DRX)) operation of a UE that monitors and receives an ISAC sensing RS (Reference Signal) (sensing signal) of a base station according to various embodiments is proposed as follows.

[0178] FIG. 10 illustrates a data communication discontinuous reception reuse method for ISAC sensing RS (sensing signal) monitoring, according to one embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0179] Referring to FIG. 10, for example, the base station may set an "ISAC Sensing RS occasion (or "downlink control signal (e.g., physical downlink control channel (PDCCH)" search space for ISAC sensing RS)") that allows the UE to monitor the ISAC sensing RS transmitted by itself (e.g., the base station) within an inactive period (e.g., a period during which the UE does not monitor the downlink control signal (e.g., physical downlink control channel (PDCCH)) of the base station for performing communication) of a communication discontinuous reception configuration (e.g., a discontinuous reception cycle, an Onduration timer, an Inactivity timer, a HARQ RTT timer (hybrid automatic repeat request round trip timer) and / or a Retransmission Timer, etc.). For example, a "downlink physical channel (e.g., physical downlink control channel)" search space may refer to a downlink resource grid area in which downlink physical channels (e.g., physical downlink control channels) may be transmitted. For example, a UE may perform blind decoding throughout this search space to find physical downlink control channel data (e.g., downlink control information (DCI)).

[0180] For example, the base station can set an ISAC sensing RS occasion after a certain offset (e.g., set by the base station to the UE via a dedicated RRC message, system information, and / or pre-configuration) from the end time of the onduration of the communication discontinuous reception. For example, the UE can monitor or receive the ISAC sensing RS transmitted by the base station in the ISAC sensing RS occasion after this offset when the onduration of the communication discontinuous reception expires. For example, the UE can monitor the ISAC sensing RS transmitted by the base station in the ISAC sensing RS occasion after the offset from the time when the onduration timer expires. However, for example, if an extended active time for communication (e.g., a discontinuous reception inactivity timer operation period and / or a discontinuous reception retransmission timer operation period) overlaps with an ISAC sensing RS (sensing signal) occasion, the UE may perform an extended active time operation for communication (e.g., receiving a base station signal and / or message for communication) without performing an ISAC sensing RS (sensing signal) monitoring operation at the ISAC sensing RS (sensing signal) occasion. Or, for example, if an extended active time for communication (e.g., a discontinuous reception inactivity timer operation period and / or a discontinuous reception retransmission timer operation period) overlaps with an ISAC sensing RS (sensing signal) occasion, the UE may perform an ISAC sensing RS (sensing signal) monitoring operation at the ISAC sensing RS (sensing signal) occasion without performing an extended active time operation for communication (e.g., receiving a base station signal and / or message for communication).Alternatively, for example, if the UE overlaps the extended active time for communication (e.g., the discontinuous reception inactivity timer operation period and / or the discontinuous reception retransmission timer operation period) with the ISAC sensing RS occasion, the UE may perform both the extended active time operation for communication (e.g., receiving base station signals and / or messages for communication) and the ISAC sensing RS monitoring operation during the ISAC sensing RS occasion (e.g., performing the communication discontinuous reception active time operation and monitoring the downlink ISAC sensing RS during the remaining active time period). For example, if there are multiple ISAC sensing RS occasions within the inactive period, the first ISAC sensing RS occasion (1. st The second ISAC Sensing RS occasion (2) in the Sensing RS (sensing signal) of the ISAC Sensing RS occasion ndThe location of an ISAC Sensing RS occasion can be indicated. Alternatively, for example, an interval (or offset) between ISAC sensing RS occasions can be preset and shared with the UE, and the UE can monitor the next ISAC sensing RS occasion after this interval (or offset). In addition, for example, the base station may or may not set an ISAC sensing RS occasion within a communication discontinuous reception cycle. For example, the base station may transmit an "ISAC sensing RS (sensing signal) occasion presentation indication (e.g., 0: indicating that there is no ISAC sensing RS (sensing signal) occasion in the inactive period of the cycle, 1: indicating that there is an ISAC sensing RS (sensing signal) occasion in the inactive period of the cycle)" to the UE at a certain offset from the start time of the communication discontinuous reception cycle (or, at the start time of the communication discontinuous reception cycle), so that the UE may determine whether to monitor the ISAC sensing RS (sensing signal) transmitted by the base station in the inactive period of the discontinuous reception cycle or operate in a sleep mode (a mode in which the base station does not monitor downlink signals transmitted).

[0181] For example, the base station can configure periodic downlink ISAC sensing RS (sensing signal) transmission resources (e.g., downlink semi-persistent scheduling for ISAC sensing RS (sensing signal) transmission of gNB) and transmit them to the UE. For example, in this case, the UE can regard the periodic downlink ISAC sensing RS (sensing signal) transmission resource period as an active time for communication discontinuous reception, and wake up even during a discontinuous reception inactive period to monitor the downlink ISAC sensing RS (sensing signal) transmitted by the base station.

[0182] In the present disclosure, for example, the base station may set ps-MonitorPeriodicISAC-RS to False so that the UE may skip the downlink ISAC RS (sensing signal) monitoring or reception operation in the periodic downlink ISAC RS (sensing signal) monitoring (or reception) period of the UE to maximize the power saving gain of the UE. For example, the UE may skip the downlink ISAC RS (sensing signal) monitoring or reception operation in the periodic downlink ISAC RS (sensing signal) monitoring period if it determines that ps-MonitorPeriodicISAC-RS is indicated as False. (For example, ps-MonitorPeriodicISAC-RS may instruct the UE to monitor periodic ISAC sensing RS (sensing signal) report(s) (when drx-onDurationTimer is not started). For example, if the field is absent (or the field is set to "false"), the UE may not monitor periodic ISAC sensing RS (sensing signal) report(s) (when drx-onDurationTimer is not started).)

[0183] Hereinafter, a description is given of a dedicated discontinuous reception setting definition for ISAC sensing RS (sensing signal) monitoring according to various embodiments.

[0184] FIG. 11 illustrates a dedicated discontinuous reception method for monitoring ISAC sensing RS (sensing signal) according to one embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0185] Referring to FIG. 11, for example, a UE may define an ISAC-dedicated discontinuous reception configuration for monitoring ISAC sensing RSs (sensing signals) transmitted by a base station. For example, the ISAC-dedicated discontinuous reception configuration may be composed of a discontinuous reception cycle and an onduration timer. For example, the UE may monitor or receive ISAC sensing RSs (sensing signals) transmitted by a base station in the onduration timer and operate in a sleep mode until the next discontinuous reception cycle (e.g., an inactive period from the expiration of the current onduration to the start of the next discontinuous reception cycle: during this period, the UE may not perform an ISAC sensing RS (sensing signal) monitoring operation transmitted by the base station).

[0186] For example, the UE may perform only the ISAC sensing RS (sensing signal) monitoring operation without performing the monitoring operation of the base station downlink signal for communication purposes during the onduration timer period of the ISAC dedicated discontinuous reception configuration. Alternatively, for example, the UE may perform both the monitoring operation of the base station downlink signal for communication purposes (e.g., the downlink physical control signal and / or the physical downlink control channel) and the ISAC sensing RS (sensing signal) monitoring operation during the onduration timer period of the ISAC dedicated discontinuous reception configuration. For example, a search space set for monitoring a downlink control signal for communication (e.g., a physical downlink control channel) and a search space set for monitoring ISAC sensing RS (sensing signals) can be independently configured and allocated to the UE so that the UE can perform both the monitoring operation of a base station downlink signal (e.g., a downlink physical control signal and / or a physical downlink control channel) for communication purposes and the monitoring operation of an ISAC sensing RS (sensing signal) during an active time (e.g., an onduration timer) of an ISAC dedicated discontinuous reception configuration. For example, the UE can perform both the monitoring operation of a base station downlink signal (e.g., a downlink physical control signal and / or a physical downlink control channel) and the monitoring operation of an ISAC sensing RS (sensing signal) during an active time (e.g., an onduration timer) using each of the allocated or configured search space sets.Also, referring to the embodiment of FIG. 11, for example, the base station can set an "ISAC sensing RS occasion (or "search space for downlink physical channel (e.g., physical downlink control channel)" ISAC sensing RS (sensing signal)") to allow the UE (e.g., the base station) to monitor the ISAC sensing RS (sensing signal) transmitted by itself during an inactive period of the ISAC dedicated discontinuous reception configuration (e.g., a period when the UE does not monitor the downlink control signal (e.g., physical downlink control channel) of the base station). The "downlink physical channel (e.g., physical downlink control channel)" search space can mean a downlink resource grid region in which the "downlink physical channel (e.g., physical downlink control channel)" can be transmitted. For example, the UE can perform blind decoding throughout the search space to find physical downlink control channel (e.g., downlink control information (DCI)) data. For example, the base station can set an ISAC sensing RS occasion after a certain offset (e.g., the base station can set it to the UE via a dedicated RRC message, system information, and / or preset) from the end time of the onduration of the ISAC-dedicated discontinuous reception. For example, the UE can monitor or receive the ISAC sensing RS transmitted by the base station in the ISAC sensing RS occasion after this offset when the onduration of the discontinuous reception expires. For example, if there are multiple ISAC sensing RS occasions within the inactivity period, the sensing RS of the first ISAC sensing RS occasion can indicate the location of the second ISAC sensing RS occasion.Alternatively, for example, an interval (or offset) between ISAC sensing RS (sensing signal) occasions can be set in advance and shared with the UE, and the UE can monitor the next ISAC sensing RS (sensing signal) after this interval (or offset).

[0187] In the present disclosure, for example, the base station may set ps-MonitorPeriodicISAC-RS to false so that the UE may skip the downlink ISAC RS (sensing signal) monitoring or reception operation in the periodic downlink ISAC RS (sensing signal) monitoring (or reception) period of the UE to maximize the power saving gain of the UE. For example, the UE may skip downlink ISAC RS (sensing signal) monitoring or reception operation in the periodic downlink ISAC RS (sensing signal) monitoring period if it determines that the ps-MonitorPeriodicISAC-RS is indicated as false. (For example, ps-MonitorPeriodicISAC-RS may instruct the UE to monitor periodic ISAC sensing RS (sensing signal) report(s) (when drx-onDurationTimer is not started). For example, if the field is absent (or the field is set to "false"), the UE may not monitor periodic ISAC sensing RS (sensing signal) report(s) (when drx-onDurationTimer is not started).)

[0188] Hereinafter, a communication discontinuous reception operation for periodic ISAC sensing RS (sensing signal) transmission of a UE according to various embodiments is described.

[0189] FIG. 12 illustrates a method of an embodiment 1 of an uplink ISAC sensing RS (sensing signal) transmission operation in a communication discontinuous reception 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.

[0190] Referring to FIG. 12, for example, a UE operating discontinuous reception (e.g., discontinuous reception operation for monitoring a physical downlink control channel of a base station) may transmit periodic ISAC sensing RS (sensing signal) to the base station in a section in which the onduration timer of the discontinuous reception has not started, if ps-TransmitPeriodicISAC-RS is set to True in the Downlink Control Information of Power Saving (DCP) setting. (For example, ps-TransmitPeriodicISAC-RS may instruct the UE to transmit periodic ISAC sensing RS (sensing signal) report(s) when drx-onDurationTimer has not started. For example, if the field is absent, the UE may not transmit periodic ISAC sensing RS (sensing signal) report(s) when drx-onDurationTimer has not started.) The ps-TransmitPeriodicISAC-RS parameter may be configured by the base station together with the discontinuous reception configuration and communicated to the UE (for example, via a dedicated RRC message, system information, and / or preset). For example, the periodic uplink ISAC RS (sensing signal) transmission resource may be configured or preset by the base station (for example, via a dedicated RRC message and / or system information).

[0191] In the present disclosure, for example, the base station can set ps-TransmitPeriodicISAC-RS to false so that the UE can skip uplink ISAC RS (sensing signal) transmission in the periodic uplink ISAC RS (sensing signal) transmission period of the UE to maximize the power saving gain of the UE. For example, if the UE determines that ps-TransmitPeriodicISAC-RS is indicated as false, the UE can skip uplink ISAC RS (sensing signal) transmission in the periodic uplink ISAC RS (sensing signal) transmission period. In addition, for example, if the sensing-RS (S-RS) (sensing signal) related detection and / or measurement is omitted for a certain period or more due to a discontinuous reception operation, the base station can set ps-TransmitPeriodicISAC-RS to false so that the UE skips the S-RS (sensing signal) reporting operation.

[0192] FIG. 13 illustrates a method of an uplink ISAC sensing RS (sensing signal) transmission operation embodiment 2 in a communication discontinuous reception 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.

[0193] Referring to FIG. 13, in the present disclosure, for example, a UE operating in discontinuous reception (e.g., discontinuous reception operation for monitoring a physical downlink control channel of a base station) may transmit periodic ISAC sensing RS (sensing signal) to the base station within the current discontinuous reception cycle if ps-TransmitPeriodicISAC-RS is set to true in the Downlink Control Information of Power Saving (DCP) setting, and if in the DCI 2_6 Wake Up Indication, referring to the embodiment of FIG. 13, sleep is indicated and the onduration timer is not started, the UE may transmit periodic ISAC sensing RS (sensing signal) report(s) to the base station. (For example, ps-TransmitPeriodicISAC-RS may instruct the UE to transmit periodic ISAC sensing RS (sensing signal) report(s) when drx-onDurationTimer is not started. For example, if there is no field In case, the UE may not transmit periodic ISAC sensing RS (sensing signal) report(s) when drx-onDurationTimer is not started.) For example, the ps-TransmitPeriodicISAC-RS parameter may be set by the base station together with the communication discontinuous reception setup and communicated to the UE (e.g., via a dedicated RRC message, system information and / or preset). For example, the periodic uplink ISAC RS (sensing signal) transmission resource may be set or preset by the base station (e.g., via a dedicated RRC message and / or system information).

[0194] In the present disclosure, for example, the base station may set ps-TransmitPeriodicISAC-RS to false to enable the UE to skip uplink ISAC RS (sensing signal) transmission in the periodic uplink ISAC RS transmission period of the UE when the onduration timer has not started within a discontinuous receive cycle (e.g., wake up indication = 0) to maximize the power saving gain of the UE. For example, the UE may skip uplink ISAC RS (sensing signal) transmission in the periodic uplink ISAC RS transmission period if it determines that ps-TransmitPeriodicISAC-RS is indicated as false. Additionally, if detection and / or measurement related to sensing-RS (S-RS) (sensing signal) is omitted for a certain period of time due to, for example, discontinuous reception operation, the base station may set ps-TransmitPeriodicISAC-RS to false to cause the UE to omit the S-RS (sensing signal) reporting operation.

[0195] FIG. 14 illustrates a method for setting a discontinuous reception pattern of a target sensing area (TSA)-specific S-RS (sensing RS) (sensing signal), according to one embodiment of the present disclosure. The embodiment of FIG. 14 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0196] Referring to FIG. 14, in the present disclosure, for example, a discontinuous reception pattern of a S-RS (sensing RS) (sensing signal) specific to a target sensing area (TSA) can be set. For example, the target sensing area here can be defined as a physical area or a set of S-RS (sensing signal) resources. In addition, for example, if the S-RS (sensing signal) reception operation is linked to a downlink (physical) control signal (e.g., a physical downlink control channel), a discontinuous reception pattern can be set for a separately set RNTI (for the purpose of ISAC operation) (e.g., a UE group RNTI) other than a C-RNTI (Cell-radio network temporary identifier). For example, in the case of UE to UE sensing, if it is defined in the form of overhearing uplink resources (or messages) (transmitted by another terminal), then from the terminal's perspective, for example, a discontinuous reception pattern related to monitoring a downlink (physical) control signal (e.g., a physical downlink control channel) and a discontinuous reception pattern related to receiving an S-RS (sensing signal) can be separately configured. For example, the discontinuous reception pattern can be used for purposes such as beam pairing operation related to an S-RS (sensing signal) and interference measurement related to an S-RS (sensing signal) (transmitted by another terminal).

[0197] For example, referring to (a) of FIG. 14, for example, the target sensing region may be single or multiple. For example, a discontinuous reception pattern for a target sensing region-specific S-RS (sensing RS) (sensing signal) may be set for each target sensing region. For example, the active times of the discontinuous reception patterns for a plurality of target sensing region-specific S-RS (sensing RS) (sensing signals) may be set so as not to overlap with each other for each target sensing region. For example, referring to (b) and / or (c) of FIG. 14, all and / or part of the discontinuous reception patterns for a plurality of target sensing region-specific S-RS (sensing RS) (sensing signals) may be set to overlap in all and / or part of the active times, or a specific active time may be included in another active time. For example, a discontinuous reception pattern for a target sensing area specific S-RS (sensing RS) (sensing signal) is not limited to the embodiment of FIG. 14, but can be combined with various embodiments of the present disclosure.

[0198] For example, S-RS (sensing signal) reception can exist in two forms: “only S-RS (sensing signal)” or “S-RS (sensing signal) + communication data”. For example, in the latter case, if an S-RS (sensing signal) specific discontinuous reception pattern is configured, the communication data related discontinuous reception pattern and the S-RS related discontinuous reception pattern can be operated simultaneously. For example, in another way, the UE can use the discontinuous reception configuration in a form where only the discontinuous reception pattern with a relatively short period among the two is applied. In addition, for example, the S-RS (sensing signal) reception operation can be allowed within the “communication data” related active time (for example, the discontinuous reception onduration timer, the discontinuous reception inactivity timer, and / or the discontinuous reception retransmission timer). For example, in this case, the active time can be operated in a form in which the active time is further extended. Or, for example, the communication data reception operation can be allowed within the “S-RS (sensing signal)” related active time. For example, in this case, it may work in the form of additional extension of active time.

[0199] For example, in a situation where “ON-Demand S-RS (sensing signal) transmission (e.g., S-RS transmission upon request of a base station and / or a counterpart terminal)” or “S-RS (sensing signal) retransmission is supported,” separate scheduling request (RS) resources and / or physical uplink control channel (PUCCH) resources may be set for each S-RS (sensing signal) resource. For example, at this time, a separate process for sensing operation (e.g., a process different from a hybrid automatic repeat request (HARQ) process) may be defined, so that a discontinuous reception operation related to S-RS (sensing signal) may be performed.

[0200] For example, the sensing operation may be performed in a manner such that “the terminal directly detects and / or measures the S-RS (sensing signal) to derive and / or utilize the sensing information” and “the terminal reports the S-RS-related detection and / or measurement values ​​to the base station and / or SMF, and the base station and / or SMF derive and / or utilize the sensing information.” For example, in the latter case, in order to reduce the reporting-related latency of the terminal, reporting resources for each S-RS (sensing signal) may be set in advance (for example, scheduling request resources only for reporting S-RS (sensing signal) detection and / or measurement values ​​and scheduling request resources for the other cases may be further separately set). Of course, separate discontinuous reception patterns may be set for, for example, two operations of different characteristics.

[0201] FIG. 15 illustrates a method for performing sensing for multiple target sensing areas according to an embodiment of the present disclosure. The embodiment of FIG. 15 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.

[0202] Referring to FIG. 15 , for example, the target sensing region may be singular or plural. For example, the target sensing region may be a physical location region, or a set of S-RS (sensing-RS) (sensing signal) resources. For example, if the target sensing region is a plurality of physical regions, referring to FIG. 15 (a), the plurality of target sensing regions may be regions that do not overlap each other. For example, referring to FIG. 15 (b) and / or FIG. 15 (c), all and / or part of the plurality of target sensing regions may overlap each other, and / or all and / or part of a specific target sensing region may be included within another target sensing region. For example, the target sensing region is not limited to the embodiment of FIG. 15 , but may be combined with various embodiments of the present disclosure.

[0203] The method proposed in this disclosure may have various improved effects compared to prior art, although these effects are not limited to those presented in this disclosure. For example, power saving can be maximized during sensing operations by setting a specific discontinuous reception pattern for a target sensing area (TSA) and performing a reception operation for a sensing RS (sensing signal). Furthermore, resource conflicts with resources associated with other target sensing areas can be reduced, for example.

[0204] According to various embodiments of the present disclosure, a power saving operation for ISAC sensing RS (sensing signal) transmission and ISAC sensing RS (sensing signal) reception is proposed.

[0224] FIG. 16 illustrates a method for a first device to perform wireless communication 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.

[0225] Referring to FIG. 16, in step S1610, the first device may acquire at least one piece of configuration information for discontinuous reception. In step S1620, the first device may select first configuration information related to the first target sensing area from among the at least one piece of configuration information. In step S1630, the first device may receive a sensing signal related to the first target sensing area based on the first configuration information.

[0226] Additionally, for example, second configuration information related to a second target sensing region may be selected from among the at least one configuration information. For example, the first configuration information may be configuration information independent of the second configuration information. For example, a first reporting resource related to receiving a sensing signal related to the first target sensing region may be set independently of a second reporting resource related to receiving a sensing signal related to the second target sensing region.

[0227] For example, the first configuration information may be configuration information for a wireless network temporary identifier associated with sensing that is independently set from the cell wireless network temporary identifier based on whether reception of a sensing signal associated with the first target sensing area is related to a downlink control signal.

[0228] For example, the first configuration information may be configuration information independent of the third configuration information used to monitor a downlink control signal, based on the first configuration information being configuration information used to monitor a sensing signal.

[0229] For example, the first target sensing area may be a physical area or a set of resources associated with the sensing signal.

[0230] For example, reception of communication data may be permitted within an active time for a sensing signal associated with the first target sensing region, which is set based on the first configuration information. For example, the active time for a sensing signal associated with the first target sensing region may be extended based on the fact that reception of the communication data is permitted within the active time for a sensing signal associated with the first target sensing region.

[0231] For example, reception of communication data may not be permitted within an active time for a sensing signal associated with the first target sensing area, which is set based on the first setting information.

[0232] For example, the sensing signal associated with the first target sensing region may be a sensing signal based on a request of the device or a retransmitted sensing signal. For example, based on the sensing signal associated with the first target sensing region being a sensing signal based on a request of the device or a retransmitted sensing signal, a scheduling request resource or a physical uplink control channel resource for the sensing signal associated with the first target sensing region may be configured. For example, the first configuration information may be configuration information associated with a process for sensing. For example, the process for sensing may be an independent process from a process for a hybrid automatic repeat request.

[0233] For example, the fourth setting information used for obtaining sensing information related to the sensing signal can be set independently from the fifth setting information used for reporting related to the sensing signal.

[0234] The above 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 first device (100) to obtain at least one piece of configuration information for discontinuous reception. Then, the processor (102) of the first device (100) can control the first device (100) to select first configuration information related to a first target sensing area from the at least one piece of configuration information. Then, the processor (102) of the first device can control the transceiver (106) to receive a sensing signal related to the first target sensing area based on the first configuration information.

[0235] 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: acquire at least one configuration information for discontinuous reception; select first configuration information related to a first target sensing region from among the at least one configuration information; and receive a sensing signal related to the first target sensing region based on the first configuration information.

[0236] 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.

[0261] FIG. 20 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 20 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.

[0262] Referring to FIG. 20, 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. 20 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 19. The hardware elements of FIG. 20 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 19. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 19. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 19, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 19.

[0263] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 20. 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).

[0264] 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.

[0265] 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.

[0266] 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. 20. For example, a wireless device (e.g., 100, 200 of FIG. 19) 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.
