[0039] FIG. 1 illustrates a device-to-device communication procedure according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

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

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

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

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

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

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

[0046] FIG. 2 illustrates a radio protocol architecture according to an embodiment of the present disclosure. The embodiment of FIG. 2 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.

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

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

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

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

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

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

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

[0054] FIG. 3 illustrates the structure of a wireless frame according to an embodiment of the present disclosure. The embodiment of FIG. 3 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.

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

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

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

[0058] CP type SCS (15*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

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

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

[0061] FIG. 4 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 4 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.

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

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

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

[0065] FIG. 5 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 5 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.

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

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

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

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

[0070] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. For example, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a 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.

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

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

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

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

[0088] - Integrated sensing and communication (ISAC)

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

[0090] FIG. 7 illustrates an example of a communication scenario based on a 6G system, according to an embodiment of the present disclosure. The embodiment of FIG. 7 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0091] Referring to FIG. 7, NTN communication can be performed based on satellite networks, high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS), 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.

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

[0093] Integrated Sensing and Communications (ISAC) is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the environment and / or the characteristics of objects within the environment. Because radio frequency sensing does not require a device to connect to the object through a network, it can provide services for object positioning without a device. The ability to obtain range, velocity, and angle information from radio frequency signals can enable a wide range of new capabilities, such as various object detection, object recognition (e.g., vehicles, humans, animals, UAVs), and high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to a variety of industries (e.g., unmanned aerial vehicles, smart homes, V2X, factories, railways, public safety, etc.), enabling applications such as intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, and health and traffic management. In some cases, wireless sensing can utilize non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP-based sensing. For example, the operation of a wireless sensing service (e.g., sensing operation) may depend on the transmission, reflection, and scattering processing of wireless sensing signals. Therefore, wireless sensing may provide an opportunity to enhance existing communication systems from communication networks to wireless communication and sensing networks. FIG. 8 illustrates an example of a sensing operation according to an embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. Specifically, FIG. 8 (a) illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and FIG. 8 (b) illustrates an example of sensing using a separated sensing receiver and a sensing transmitter (e.g., bistatic sensing).

[0126] In the present disclosure, the TRP and the base station may be replaced and used as the same entity.

[0127] In the present disclosure, the sensing signal and the sensing RS (reference signal) can be interpreted and used interchangeably.

[0128] In the present disclosure, a sensing message may be interchangeably used and interpreted as a sensing measurement report, an RRC message for a sensing operation, or a MAC CE for a sensing operation.

[0129] For example, an SL PRS transmission resource may be composed of an SL PRS resource set consisting of the following information:

[0130] - SL PRS resource set ID

[0131] - SL PRS Resource ID List: List of SL PRS resource IDs within the SL PRS resource set.

[0132] - SL PRS resource type: can be set to periodic or aperiodic or semi-persistent or on-demand

[0135] - Path loss reference for SL PRS power control: Can be set to SL SSB or DL ​​PRS or UL SRS or UL SRS for positioning or PSCCH DMRS or PSSCH DMRS or PSFCH or SL CSI RS, etc.

[0136] For example, the above SL PRS resource set may be composed of SL PRS resources composed of the following information.

[0137] - SL PRS resource ID

[0138] - SL PRS comb size: Interval between REs where SL PRS is transmitted within a symbol

[0146] - SL PRS periodicity: the period in the time domain between SL PRS resources, a unit of physical or logical slot in the resource pool where SL PRS is transmitted.

[0147] - SL PRS Offset: The offset in the time domain from the start of the first SL PRS resource to the reference timing, in units of physical or logical slots in the resource pool where the SL PRS is transmitted. The reference timing may be SFN=0 or DFN=0, or the time of successful reception or decoding of RRC / MAC-CE / DCI / SCI associated with the SL PRS resource.

[0148] - SL PRS sequence ID

[0149] - SL PRS spatial relation: can be set to SL SSB or DL ​​PRS or UL SRS or UL SRS for positioning or PSCCH DMRS or PSSCH DMRS or PSFCH or SL CSI RS, etc.

[0150] - SL PRS CCH: SL PRS control channel. Can signal SL PRS resource configuration information and resource location, etc.

[0151] Meanwhile, for example, when a terminal has logical channel data and / or MAC CE and / or control message (e.g., PC5-S message or PC5 RRC message) to transmit, the terminal may perform the LCP procedure according to the LCP (Logical Channel Prioritization) priority order as follows:

[0152] 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 with a higher priority based on priority. For example, when the terminal has MAC CEs and data to transmit, if the destinations of the MAC CEs and the data are different, the terminal can first multiplex a message with a higher priority (e.g., MAC CE) into the MAC PDU to generate a MAC PDU. In addition, for example, when the destinations of messages are the same, the terminal can perform a multiplexing operation for generating a MAC PDU by preferentially selecting a message with a higher priority.

[0153] 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., sensing latency: the time it takes for a terminal that triggers sensing to trigger the sensing procedure and for a receiving terminal to receive the sensing result of the target object, or sensing accuracy, etc.). For example, in ISAC, 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, and the terminal can perform a sensing operation (e.g., transmitting a sensing reference signal and / or receiving a sensing reference signal) based on the sensing QoS.

[0154] For example, sensing in ISAC can be considered as a higher layer service that must satisfy sensing QoS (or sensing quality) based on sensing results, and a new QoS (e.g., Sensing QoS Flow ID (SQFI)) for the ISAC sensing service can be defined as follows.

[0155] - SQFI (Sensing QoS Flow ID)

[0156] - SQFI 1 ~ 8: For example, they can be distinguished according to the level of sensing QoS requirements. For example, sensing QoS requirements can include sensing accuracy, sensing latency (e.g., latency boundary from sensing triggering to receiving sensing results), or sensing priority (e.g., priority that can be used to determine which sensing service is triggered first based on priority when multiple sensing procedures are required). For example, a sensing service with a smaller (or higher) SQFI value can be defined as having a tighter QoS requirement (e.g., a sensing service requiring high sensing accuracy, or a sensing service requiring low / lower / lowest sensing latency).

[0157] Additionally, ISAC defines terminal and TRP (or base station) operations to support sensing services such as detection, localization, and tracking.

[0158] For example, the sensing QoS for ISAC services (detection, localization, tracking, etc.) could be as follows:

[0159] - Detection QoS: detection probability, false alarm probability

[0160] - Localization QoS: localization of the static objects, QoS parameters of localization (e.g., time delay, angle of arrival)

[0161] - Tracking QoS: Tracking the status changes of moving targets (e.g., vehicles or drones) (range, angle, velocity, etc.)

[0162] FIG. 9 illustrates a support scenario for sensing services in an ISAC, according to an embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0163] Referring to Fig. 9, the six main sensing modes are as follows. Specifically, Fig. 9 (a) shows gNB mono-static. In this case, the same gNB can perform both Tx and Rx roles. Fig. 9 (b) shows gNB bi-static. In this case, one gNB can perform the Tx role and the other gNB can perform the Rx role. Fig. 9 (c) shows gNB-to-UE bi-static. In this case, the gNB can perform the Tx role and the UE can perform the Rx role. Fig. 9 (d) shows UE-to-gNB bi-static. In this case, the UE can perform the Tx role and the gNB can perform the Rx role. Fig. 9 (e) shows UE mono-static. In this case, the same UE can perform both Tx and Rx roles. Figure 9 (f) shows a UE bi-static. In this case, one UE can perform the Tx role and another UE can perform the Rx role.

[0164] Meanwhile, according to the prior art, although there is a specific definition of each system information for the initial setup related to communication services and a definition of the configuration information included in each system information, each system information for the initial setup related to sensing services has not yet been defined. In this case, the following problems may occur. For example, if system information related to sensing services is not transmitted and received during the initial setup procedure, a separate RRC connection may need to be performed for the sensing service or an additional signaling procedure may be required, which may result in overhead and latency in the initial setup for the sensing service. Alternatively, for example, since the sensing service may be managed as a separate service from the communication service, even if coverage for communication is secured through existing system information, coverage for sensing may not be secured, and therefore operations related to sensing signal monitoring and sensing result reporting related to the sensing service may not be performed smoothly. Or, for example, since existing system information does not include configuration information related to sensing coverage, target object / target sensing area, and sensing signal cycle, even if a sensing service is triggered for the UE, the accuracy and stability of sensing performed by the UE may be degraded, and problems of detection failure or false detection may occur.

[0165] In this disclosure, a method for transmitting an ISAC sensing signal using different spectrum resources is proposed as follows.

[0166] In addition, the present disclosure proposes an idle mode (e.g., an RRC state in which an RRC connection between a base station (or TRP) and a terminal is not established) operation method for supporting an ISAC sensing service and a device supporting the same, as follows.

[0167] For example, a base station may periodically transmit a System Information Block (SIB) N to perform scheduling for transmitting a sensing signal (e.g., a sensing reference signal) of a sensing transmitter and / or monitoring a sensing signal or transmitting sensing data (e.g., a sensing measurement report) of a sensing receiver. For example, the base station may include scheduling information (e.g., a transmission period of SIB N, etc.) related to transmission of SIB N including ISAC sensing scheduling information in SIB 1 and transmit the SIB 1 to terminals within cell coverage. For example, the following information may be included in SIB N:

[0168] Information that may be included in a SIB N (e.g., SIB for ISAC):

[0169] - Sensing coverage of the serving cell and / or location information of the serving cell (e.g., relative location information or absolute location information)

[0170] - Serving cell idle DRX configuration (e.g., in idle DRX for ISAC, DRX cycle / period or onduration timer for monitoring reference signals or cell search, etc.):

[0171] For example, an idle mode terminal can wake up for every idle DRX cycle / period included in SIB N and monitor sensing reference signals transmitted by a TRP (or base station). For example, the idle DRX cycle / period for monitoring ISAS sensing signals and ISAC target cell search can be set to a multiple of a legacy idle DRX cycle / period for a communication service (e.g., LTE or NR) (e.g., N × legacy idle DRX cycle / period, where the value of N can be conveyed or pre-configured via SIB N (e.g., SIB for ISAC).

[0172] FIG. 10 illustrates DRX configuration for communication and DRX configuration for ISAC according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0173] Referring to FIG. 10, a short idle DRX cycle / period (1010) represents a legacy idle DRX cycle / period for a communication server, and a long idle DRX cycle / period (1020) represents a DRX cycle / period for monitoring ISAC sensing reference signals and searching for ISAC sensing service target cells. For example, in an idle DRX cycle / period (1010) related to communication, a terminal may skip monitoring a signal transmitted by a base station for a sensing service (e.g., an ISAC sensing reference signal or an ISAC sensing service dedicated SIB). Additionally, for example, in an ISAC idle DRX cycle / period (1020), the terminal may skip monitoring a signal transmitted by the base station for a communication service (e.g., a communication-only SIB or a communication-only reference signal).

[0174] - Neighbor cell idle DRX configuration (e.g., DRX cycle / period or onduration timer):

[0175] For example, if an idle mode terminal needs to monitor a sensing signal (e.g., a sensing reference signal) of a neighbor TRP (or base station), it can wake up in the idle DRX cycle / period of the neighbor cell included in SIB N and monitor the sensing reference signal transmitted by the neighbor TRP (or base station).

[0176] - Target sensing area (TSA) information of the serving cell:

[0177] For example, it may include information related to the sensing object, location information of the sensing TSA (e.g., absolute location information or relative location information), period information of the sensing reference signal, and uplink resource information for reporting sensing data. Alternatively, for example, if the ISAC manages separate RACH resources, RACH resource allocation information may be included in the SIB for the ISAC.

[0178] - TSA (target sensing area) information of neighboring cells:

[0179] For example, it may include information related to the sensing object, location information of the sensing TSA (e.g., absolute location information or relative location information), period information of the sensing reference signal, and uplink resource information for reporting sensing data. Alternatively, for example, if the ISAC manages separate RACH resources, RACH resource allocation information may be included in the SIB for the ISAC.

[0180] - DRX cycle (cycle / period) for monitoring sensing reference signals or cell search in i-DRX (idle mode DRX) for ISAC:

[0181] For example, the idle DRX cycle / period for ISAC can be defined as "N × legacy idle DRX cycle / period", where the value of N can be conveyed or pre-configured via SIB N (e.g., SIB for ISAC).

[0182] Alternatively, for example, for seamless TSA (target sensing area) sensing and / or object sensing during handover of terminals, the following information may be exchanged between TRPs or between terminals or between TRPs and terminals.

[0183] - Information required for handover for sensing:

[0184] Information about pre-allocated periodic resources (e.g., configured grant for ISAC sensing measurement report) to transmit sensing data (e.g., sensing measurement report) to the target cell (or base station, or TRP) when handing over to a neighbor cell (or target cell (or base station, or TRP)).

[0185] - Information about the sensing object (e.g., object position (e.g., relative position or absolute position) information for object identification) that was being sensed in the previous cell or information about the target sensing area (TSA) that was being sensed in the previous cell (e.g., TSA position (e.g., relative position or absolute position) information for TSA identification)

[0186] In addition, the present disclosure proposes an idle mode operation (e.g., on-demand sensing reference signal) that enables the sensing reference signal to be transmitted only when requested by a terminal in order to save power of the TRP (or base station), as follows.

[0187] For example, if a sensing service is triggered when the UE is in RRC idle state (e.g., a new RACH condition), the UE may transmit an on-demand reference signal request message to the TRP (or base station), and the TRP (or base station) may transmit a sensing reference signal based on the request of the UE. In addition, for example, a random access channel (RACH) (e.g., a new RACH condition) procedure for an on-demand reference signal request of the UE in the RRC idle state may be performed. Alternatively, for example, the base station (or TRP) may allocate periodic (e.g., long period) uplink resources to the UE, and the UE may transmit an on-demand reference signal request message to the base station (or TRP) using the periodic uplink resources (e.g., configured grant) when needed.

[0188] FIG. 11 illustrates a method for a UE in an RRC_IDLE state to perform sensing operations based on the reception of system information, according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0189] Referring to FIG. 11, a UE in an RRC idle state can periodically monitor a synchronization signal block (SSB) to perform a cell search, and select a cell with the best received signal strength as a serving cell based on measurements such as RSRP. For example, the UE can select cell #1 as a serving cell. For example, the UE can receive SIB 1 related to cell #1 from a base station related to cell #1. For example, SIB 1 can include scheduling information related to an SIB for sensing (e.g., transmission period information of an SIB for ISCA sensing, etc.). For example, the UE can receive an SIB for sensing based on SIB 1. Or, for example, when a sensing service is triggered for a UE, the UE may request an SIB for sensing related to the sensing service after receiving SIB 1 (e.g., a request based on an RRC message or MAC CE), and the base station may transmit an SIB for sensing to the UE in response to the request. For example, when the sensing service triggered for the UE is a sensing service related to sensing for a target sensing area within cell #1, the UE may receive SIB 1 related to cell #1 and an SIB for sensing, and transmit and receive a sensing signal for sensing the target sensing area within cell #1 based on the SIB for sensing.

[0190] For example, the SIB for sensing received by the UE may include sensing coverage information of the serving cell, location information of the serving cell, DRX configuration information for sensing in the serving cell (e.g., information related to an active time for monitoring / receiving sensing signals or DRX cycle information for sensing), sensing signal information related to a sensing service (e.g., a transmission cycle of a sensing signal or resource information related to a sensing signal), target sensing area information related to the sensing service, etc. For example, the UE may perform beam forming or beam switching operation for monitoring sensing signals transmitted from at least one TRP included in the serving cell based on the sensing coverage information of the serving cell. Or, for example, the UE may perform scheduling (e.g., beam configuration for monitoring sensing signals, priority setting related to transmission / reception of sensing signals, or priority setting related to measurement reporting for sensing signals, etc.) to ensure sensing for a specific area based on the sensing coverage information of the serving cell. Alternatively, for example, the UE may apply a quality of service (QoS) (e.g., sensing precision or sensing cycle, etc.) related to a sensing service triggered for the UE based on the sensing coverage information of the serving cell. Alternatively, for example, the UE may perform cooperative sensing by receiving a sensing signal from a TRP associated with a neighbor cell for sensing an area outside the sensing coverage based on the sensing coverage information of the serving cell. Alternatively, for example, the UE may determine whether to perform cell reselection or handover for sensing an area outside the sensing coverage based on the sensing coverage information of the serving cell. Alternatively, for example, the UE may utilize location information of the serving cell to improve the accuracy of sensing.Alternatively, for example, the UE may perform monitoring of sensing signals transmitted from a TRP associated with the serving cell based on DRX configuration information associated with the serving cell to save power.

[0191] Meanwhile, for example, as described above, if the UE selects cell #1, but the sensing service triggered for the UE is related to cell #2 neighboring cell #1 (e.g., if the target object related to the sensing service is related to cell #2, not cell #1), it may be necessary to monitor the sensing signal transmitted in the TRP related to cell #2. Accordingly, for example, the SIB for the sensing may include DRX configuration information for sensing in cell #2 neighboring cell #1 (e.g., information related to the active time for monitoring / receiving the sensing signal or DRX cycle information for sensing), location information of cell #2, sensing signal information transmitted in the TRP related to cell #2 (e.g., transmission cycle of the sensing signal or resource information related to the sensing signal), target object information related to the sensing service, etc. In this case, for example, as described above, the UE can perform monitoring of sensing signals transmitted from the TRP associated with cell #2 based on the information included in the SIB for sensing, and perform sensing of a target object associated with cell #2.

[0192] Alternatively, for example, if the UE needs to monitor sensing signals transmitted by a TRP associated with cell #2 rather than a TRP associated with cell #1 due to mobility of a target object sensed by the UE (e.g., if the target object moved from cell #1 to cell #2), the UE may receive information to perform a handover. For example, the information to perform a handover may include information related to sensing signals transmitted by a TRP associated with cell #2, information related to resources for reporting measurement results for sensing signals transmitted by the TRP associated with cell #2. Or, for example, if the UE performs a handover, the UE may report information related to a sensed target object based on sensing signals transmitted by a TRP associated with cell #1 to a TRP associated with cell #2 or a base station before performing the handover.

[0193] Embodiments of the present disclosure can be extended and applied to all six sensing scenarios of FIG. 9 described above.

[0194] Also, for example, the wording of "configuration" (or "designation") in the present disclosure can be extended to mean that the base station notifies the terminal through a pre-defined (PHY layer or higher layer) channel / signal (e.g., SIB, RRC, MAC CE) (and / or provided through pre-configuration and / or that the terminal notifies other terminals through a pre-defined (PHY layer or higher layer) channel / signal (e.g., SL MAC CE, PC5 RRC, etc.)). Also, for example, the wording of "PSFCH" in the present disclosure can be extended to mean "(NR or LTE) PSSCH (and / or (NR or LTE) PSCCH and / or (NR or LTE) SL SSB and / or UL channel / signal)". Also, for example, the proposal(s) of the present disclosure can be combined and used in a new way.

[0195] Also, for example, the term "specific threshold" in the present disclosure may mean a threshold that is defined in advance or set (in advance) by a higher layer (e.g., including an application layer) of a network or a base station or a terminal. Also, for example, the term "specific set value" may mean a value that is defined in advance or set (in advance) by a higher layer (e.g., including an application layer) of a network or a base station or a terminal. Also, for example, "set by the network / base station" may mean an operation in which the base station sets (in advance) to the UE via higher layer RRC signaling, sets / signals to the UE via MAC CE, or signals to the UE via DCI.

[0196] The unicast service of the present disclosure can be interpreted by replacing the source layer-2 ID and destination layer-2 ID pair.

[0197] The groupcast service of the present disclosure can be interpreted by replacing the groupcast destination layer-2 ID.

[0198] The broadcast service of the present disclosure can be interpreted by replacing the broadcast destination layer-2 ID.

[0199] The control message (or signal) and data message (or signal) of the present disclosure may mean a control message (or signal) and data message (or signal) for wireless communication (e.g., LTE communication, NR communication, 6G communication, Wi-Fi communication, Bluetooth communication, and other wireless communication) other than a radar signal.

[0200] The source ID and destination ID of the present disclosure may mean a source layer 1 ID, a destination layer 1 ID, and / or may mean a source layer 2 ID, a destination layer 2 ID.

[0201] For example, whether (some) of the proposed methods / rules of the present disclosure are applicable and / or related parameters (e.g., thresholds) can be set resource pool-specifically (or differently or independently).

[0206] Referring to FIG. 12, in step S1210, the first device may receive second system information including information for scheduling first system information related to sensing. In step S1220, the first device may receive the first system information based on the second system information. In step S1230, the first device may transmit or receive a sensing signal based on the first system information. For example, the first system information may include information related to sensing coverage of a serving cell.

[0207] For example, the first system information may include location information of the serving cell.

[0208] For example, the first system information may include first DRX (discontinuous reception) configuration information related to the serving cell for the sensing. For example, the first DRX cycle included in the first DRX configuration information may be set to a cycle that is N times longer than a second DRX cycle included in the second DRX configuration information for communication. For example, N may be set to an integer greater than 1. For example, based on the sensing signal being transmitted from a Transmission-Reception Point (TRP) related to the serving cell, monitoring of the sensing signal may be performed within the first DRX cycle. For example, cell search for a sensing service related to the sensing signal may be performed within the first DRX cycle.

[0209] For example, the first system information may include third DRX configuration information related to a neighboring cell other than the serving cell for the sensing. For example, based on the sensing signal being transmitted in a TRP related to the neighboring cell, monitoring of the sensing signal may be performed within a third DRX cycle included in the third DRX configuration information.

[0210] For example, the first system information may include at least one of target sensing area information related to the serving cell, target object information related to the serving cell, period information of the sensing signal related to the serving cell, resource information for reporting a measurement result for the sensing signal related to the serving cell, or random access channel (RACH) resource information for the sensing related to the serving cell.

For example, the first system information may include information related to sensing coverage of a serving cell.

[0217] 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: receive second system information including information for scheduling first system information related to sensing; receive the first system information based on the second system information; and transmit or receive a sensing signal based on the first system information. For example, the first system information may include information related to sensing coverage of a serving cell.

[0218] 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: receive second system information including information for scheduling first system information related to sensing; receive first system information based on the second system information; and transmit or receive a sensing signal based on the first system information.

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.

[0220] Referring to FIG. 13, in step S1310, the second device may transmit second system information including information for scheduling first system information related to sensing to the first device. In step S1320, the second device may transmit the first system information to the first device based on the second system information. For example, the first system information may include information related to the sensing coverage of a serving cell related to the second device.

[0221] The proposed method can be applied to devices according to various embodiments of the present disclosure. First, the processor (202) of the second device (200) can control the transceiver (206) to transmit second system information including information for scheduling first system information related to sensing to the first device. Then, the processor (202) of the second device (200) can control the transceiver (206) to transmit the first system information to the first device based on the second system information. For example, the first system information can include information related to the sensing coverage of a serving cell related to the second device.

[0222] 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: transmit second system information, including information for scheduling first system information related to sensing, to the first device; and, based on the second system information, transmit the first system information to the first device. For example, the first system information may include information related to sensing coverage of a serving cell associated with the second device.

[0223] 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 first system information may include information related to sensing coverage of a serving cell associated with the second device.

[0225] According to various embodiments of the present disclosure, a UE for which a sensing service is triggered can transmit and receive sensing signals based on information included in system information for sensing. Specifically, for example, since SIB 1 received in an initial setup procedure includes scheduling information for an SIB for sensing, and the SIB for sensing may include configuration information for the sensing service, such as sensing coverage, a target sensing area, a period of the sensing signal, resources for transmitting and receiving the sensing signal, and DRX configuration information for monitoring the sensing signal, the UE for which the sensing service is triggered can perform initial configuration for the sensing service without performing a separate RRC connection or an additional signaling procedure. Accordingly, for example, overhead and delay that may occur in the initial setup procedure for the sensing service can be minimized. Alternatively, for example, sensing coverage for a sensing service provided separately from a communication service may be provided to the UE, so that the UE for which the sensing service is triggered can stably monitor sensing signals within the secured sensing coverage. Alternatively, for example, a UE triggered by a sensing service may perform sensing based on configuration information included in an SIB for sensing, thereby improving the accuracy and stability of sensing. Alternatively, for example, a UE may monitor a sensing signal based on DRX configuration information for sensing among configuration information included in an SIB for sensing, thereby improving the power efficiency of a UE providing a sensing service.

[0243] Fig. 16 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of Fig. 16 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0244] Referring to FIG. 16, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operations / functions of FIG. 16 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 15. The hardware elements of FIG. 16 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 15. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 15. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 15, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 15.

[0245] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 16. Here, the codeword is an encoded bit sequence of an information block. The information block can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).

[0246] 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.

[0247] 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.

[0248] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 16. For example, a wireless device (e.g., 100, 200 of FIG. 15) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
