Description

Technical Field

[0001] The present disclosure relates to systems, methods, and devices for supporting communication and sensing. Background Art

[0002] As wireless communications have evolved over generations, technologies have been developed primarily for human-targeted services, such as voice calls, multimedia services, and data services. With the commercialization of 5G (fifth-generation) communication systems, the number of connected devices is expected to grow exponentially. An increasing number of these devices will be connected to communication networks. Examples of connected things include vehicles, robots, dashboards, home appliances, displays, smart sensors connected to various infrastructure, construction machinery, and factory equipment. Mobile devices are expected to develop in a variety of form factors, such as augmented reality glasses, virtual reality headsets, and holographic devices. To provide a variety of services by connecting hundreds of billions of devices and things in the 6G (sixth generation) era, efforts are underway to develop improved 6G communication systems. For these reasons, 6G communication systems are referred to as beyond 5G systems.

[0003] The 6G communication system, which is expected to be commercialized around 2030, will have a peak data rate of terabit (1,000 gigabit per second) and a radio latency of less than 100 μsec, and thus its rate will be 50 times that of the 5G communication system and its radio latency will be 1 / 10 that of the 5G communication system.

[0004] To achieve these high data rates and ultra-low latency, 6G communication systems are being considered in the terahertz band (e.g., the 95 GHz to 3 THz band). Due to the more severe path loss and atmospheric absorption in the terahertz band compared to the millimeter-wave band introduced in 5G, technologies that ensure signal transmission distance (i.e., coverage) are expected to become even more critical. Key technologies for ensuring coverage include the development of radio frequency (RF) components, antennas, new waveforms with better coverage than orthogonal frequency division multiplexing (OFDM), beamforming and massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, and multi-antenna transmission technologies such as massive antennas. Furthermore, new technologies for improving terahertz band signal coverage are being discussed, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable smart surfaces (RIS).

[0005] Furthermore, to improve spectrum efficiency and overall network performance, the following technologies have been developed for 6G communication systems: full-duplex technology, enabling uplink and downlink transmissions to use the same frequency resources simultaneously; network technologies that integrate satellites, high-altitude platform stations (HAPS), and other technologies; improved network architectures to support mobile base stations and optimize and automate network operations; dynamic spectrum sharing technologies with conflict avoidance based on spectrum usage prediction; the use of artificial intelligence (AI) in wireless communications to improve overall network operations by leveraging AI from the design phase of 6G development and internalizing end-to-end AI support capabilities; and next-generation distributed computing technologies to overcome the limitations of UE computing capabilities through the ultra-high-performance communication and computing resources available on the network (such as mobile edge computing (MEC) and the cloud). Furthermore, by designing new protocols for use in 6G communication systems, developing mechanisms for implementing hardware-based security environments and secure data usage, and developing technologies for maintaining privacy, efforts are underway to strengthen connectivity between devices, optimize networks, promote the softwareization of network entities, and increase the openness of wireless communications.

[0006] Research and development of 6G communication systems for hyperconnectivity, including both human-to-machine (P2M) and machine-to-machine (M2M), are expected to enable the next generation of hyperconnectivity experiences. Specifically, 6G communication systems are expected to provide services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replicas. Furthermore, 6G communication systems will enable services such as remote surgery for enhanced safety and reliability, industrial automation, and emergency response, enabling these technologies to be applied in a variety of fields, including industry, healthcare, automotive, and home appliances.

[0078] [Time-Frequency Resources]

[0079] The frame structure of a wireless communication system (eg, a 5G system) is described in more detail below with reference to the accompanying drawings.

[0080] Figure 2A is a diagram illustrating a basic structure of a time-frequency domain in a wireless communication system according to an embodiment of the present disclosure.

[0081] exist Figure 2A In the diagram, the horizontal axis refers to the time domain, and the vertical axis refers to the frequency domain. The basic unit of resources in the time domain and the frequency domain is a resource element (RE) 101, which can be defined by one orthogonal frequency division multiplexing (OFDM) symbol 102 on the time axis and one subcarrier 103 on the frequency axis. In the frequency domain, (For example, 12) consecutive REs may constitute a resource block (RB) 104. Figure 2A middle, is the number of OFDM symbols per subframe 110 for the subcarrier spacing setting (μ).

One time slot 202 or 203 may be defined as 14 OFDM symbols (i.e., the number of symbols per time slot ( )=14). One subframe 201 may consist of one or more time slots 202 and 203, and the number of time slots 202 and 203 per subframe 201 may differ according to μ (204 or 205), which is a value set for subcarrier spacing. FIG2 shows an example of a subcarrier spacing setting value μ=0 (204) and an example of a subcarrier spacing setting value μ=1 (205). When μ=0 (204), one subframe 201 may consist of one time slot 202, and when μ=1 (205), one subframe 201 may consist of two time slots (203).

[0085] [Joint Communications and Sensing (JCAS) System / Network]

[0086] The following describes a system that performs both communication and sensing. For example, a system that integrates communication and sensing functions into a single system is described. A system that performs both communication and sensing may be referred to as a JCAS system, but the terminology for the system is not limited to this. For example, the JCAS system may be referred to by other terms such as an integrated sensing and communication (ISAC) system, a joint sensing and communication (JSAC) system, a radar and communication (Radcom) system, or a dual-function radar communication (DFRC) system.

[0087] Figure 3 A JCAS system according to an embodiment of the present disclosure is shown.

[0088] Figure 3 The JCAS system 300 not only provides Figure 1 In addition to the communication functionality provided by the communication system 10, additional functionality for providing sensing and additional functionality for providing both communication and sensing may also be provided.

[0089] Reference Figure 3 , the JCAS system 300 may include at least one UE 310 (eg, UE1, UE2, etc.), at least one base station 320, and / or at least one target 330 (eg, target 1, target 2, etc.).

[0090] UE 310 may be an electronic device supporting communication functions and / or sensing functions. As an embodiment, UE 310 may include a UE, an MS, a wireless transmission / reception unit, a cellular phone, a smart phone, an MTC device, a computer, a wireless sensor, a vehicle, an IoT device, and / or an electronic device capable of performing other communication functions and / or sensing functions.

[0091] The UE 310 according to the embodiment can communicate with other UEs, or can communicate with the network (JCAS network) of the JCAS system 300 using a communication function. For example, similar to Figure 1 UE 310 may communicate with other UEs or may communicate with one or more network nodes (e.g., base station 320) in the radio access network of JCAS system 300. For example, UE 310 may receive communication signals (DL signals) from base station 320 through a communication channel and may transmit communication signals (UL signals) to base station 320.

[0092] According to an embodiment, the UE 310 may also support a sensing function. For example, the UE 310 may receive a sensing signal from the base station 320 via a sensing channel and may perform a sensing operation based on the sensing signal. For example, the UE 310 may transmit a sensing signal via a sensing channel. For example, the UE 310 may receive reflections of sensing signals transmitted from the base station 320 or another UE via a sensing channel and may perform a sensing operation based on the received reflections (reflected signals).

[0093] According to an embodiment, UE 310 may be a device registered in the JCAS network.

[0094] The base station 320 may be a network node that integrates and supports communication and sensing functions. A base station 320 that integrates and supports such communication and sensing functions may be referred to as a JCAS-enabled base station, a JSAC-enabled base station, or an ISAC-enabled base station. In an embodiment, the base station 320 is an entity that performs resource allocation for communication and sensing of the UE 310 and may be a wireless base station, a NodeB (NodeB), an eNB, a radio access unit, a network node, a network device, a node on a network, a base station controller, a TP, an AP, a relay station, a BBU, an RRU, an RRH, a CU, a DU, or a TRP.

[0095] According to an embodiment, the base station 320 can communicate with the UE 310, or can communicate with the core network of the JCAS system 300 or other networks using a communication function. For example, the base station 320 can send a communication signal (DL signal) to the UE 310 through a communication channel, and can receive a communication signal (UL signal) from the UE 310. The core network of the JCAS system 300 may include at least one network node for supporting a communication function (service) and a sensing function (service). According to an embodiment, the core network of the JCAS system 300 may be a 5G core network 5GC. As an embodiment, the 5GC may include an AMF, an SMF, an UPF, a PCF, an UDM, an UDR, an NSSF and / or an NSACF, and the description of each NF may refer to Figure 1 Depending on the implementation, the core network of the JCAS system 300 may be a core network other than 5GC (e.g., a 6G core network, a 4G (LTE) core network, etc.). In this case, the corresponding core network may include network functions (nodes) that perform the same or similar functions as the network functions (nodes) of the 5GC described above.

[0096] According to an embodiment, the base station 320 may support sensing functionality. For example, the base station 320 may transmit information required for sensing (e.g., resource allocation information for a sensing signal (e.g., time resource allocation information and / or frequency resource allocation information)). For example, the base station 320 may transmit a sensing signal via a sensing channel. For example, the base station 320 may receive reflections of sensing signals transmitted from itself, another base station, or the UE 310 via the sensing channel and may perform sensing operations based on the received reflections (reflected signals).

[0097] The target 330 is an entity to be sensed and may be a UE having a communication function (eg, Figure 1 UE 11 or Figure 3 The base station 320 (or UE 310) may transmit a sensing signal to the target 330 via a sensing channel. The base station 320 (or UE 310) may receive a reflection (reflected signal) from the target 330 and perform sensing based on the reflected signal. In this case, the reflected signal may be a reflection of the sensing signal transmitted by the base station 320 (or UE 310) or a reflection of a sensing signal transmitted by another device (e.g., another base station or another UE).

[0098] Depending on the embodiment, sensing may be performed by a single device, such as a single base station 320 or a single UE 310 (single-base scenario). Depending on the embodiment, sensing may be performed by multiple devices, such as a base station pair, a UE pair, or a UE / base station pair (dual-base scenario). Depending on the embodiment, sensing may be performed by a single device and / or a combination of multiple devices performing sensing jointly (multi-base scenario).

[0099] According to an embodiment, a sensing signal (reflection signal) reflected from the target 330 may be used to generate sensing data of the target 330 .

[0100] The sensed data may include information derived from the reflected signal (sensed information). Depending on the embodiment, the sensed information may include information that can be measured from signal strength, latency, timing, angle of arrival (AoA), time of flight (ToF), and / or other reflected signals.

[0101] In addition, the sensory data may further include a description of the sensory data, information for identifying a sensing purpose, information for identifying a sensing source, and / or information about a target associated with the sensory data (eg, target identification information, target location information, etc.).

[0102] According to an embodiment, the sensing data (or sensing information) may be used to generate a sensing result for the target. According to an embodiment, the sensing result may include information about the distance, position and / or velocity (Doppler) relative to the target.

[0103] Table 2 shows examples of elements and formulas for determining distance and speed through sensing.

[0104] [Table 2]

[0105] Referring to Table 2, the resolution (Rres) of the range that can be measured by the sensing operation can be determined based on the bandwidth (BW). The maximum range (maximum value) of the range that can be measured by the sensing operation can be determined based on the resolution (Rres) and / or the number of FFT points (N FFT ) is determined. Referring to Equation 2 in Table 2, as bandwidth BW increases, maximum range / range resolution can be improved. At the same time, due to its nature, sensing processing requires continuous frequency / bandwidth. Therefore, the maximum continuous frequency / bandwidth available in base station 320 must be used for sensing.

[0106] Referring to Table 2, the maximum value of the speed (Doppler) that can be measured by the sensing operation can be based on the interval between adjacent OFDM symbols allocated for sensing ( ) is determined. For example, with the interval ( ) is reduced, the maximum speed (maximum Doppler) can be improved. The resolution of the speed that can be measured by the sensing operation can be based on the duration of the accumulated OFDM symbols used for Doppler processing ( ) is determined. Referring to the equation in Table 2, as the duration ( ) increases, the velocity resolution (Doppler resolution) can be improved. Therefore, considering the Doppler requirements, it is necessary to set an appropriate sensing signal transmission period. As an implementation method, the duration ( ) can be associated with the number of symbols used for Doppler processing.

[0107] Depending on the implementation, the processing chain (e.g., PHY processing chain) used for communication (communication signals) can be the same as or different from the processing chain used for sensing (sensing signals). For example, the same modulation parameters, coding parameters, and / or waveform parameters can be used for communication and sensing. For example, different modulation parameters, coding parameters, and / or waveform parameters can be used for communication and sensing.

[0108] Depending on the embodiment, the RAT used for communication may be the same as or different from the RAT used for sensing.

[0109] Depending on the implementation, the same carrier (frequency carrier) or different carriers may be used for communication and sensing.

[0110] Depending on the implementation, different signal formats (structures) may be used for communication and sensing. For example, the sensing signal structure may be different from the communication signal structure.

[0111] Depending on the implementation, separate PHY channels or a common PHY channel can be used for communication and sensing. For example, separate PHY control channels (e.g., PDCCH and PUCCH) and separate PHY data channels (e.g., PDSCH and PUSCH) can be used for communication and sensing, respectively. For example, a common PHY control channel (e.g., PDCCH or PUCCH) can be used for communication and sensing. When the common PHY control channel is used for communication and sensing, the PHY data channel (e.g., PDSCH or PUSCH) can be used for communication and sensing separately or in common.

[0112] Figure 4 A multistatic sensing structure of a JCAS system according to an embodiment of the present disclosure is shown.

[0113] The sensing structures of the JCAS system can be classified into the following sensing structures according to the geometric structure.

[0114] A monostatic sensing configuration is one in which both the transmitting and receiving functions for sensing are located in the same device (or location). In a monostatic sensing configuration according to an embodiment, the transmitter that transmits the sensing signal and the receiver that receives the sensing signal may be included in the same device (e.g., a base station). In a monostatic sensing configuration according to an embodiment, a single device can transmit a sensing signal, receive the sensing signal reflected from a target, and perform sensing based on the sensing signal. In this monostatic sensing configuration, the transmitted sensing signal can act as self-interference. Therefore, methods for mitigating self-interference are necessary.

[0115] A bistatic sensing structure refers to a sensing configuration in which the transmitting and receiving functions for sensing are located in different devices (or locations). In a bistatic sensing structure according to embodiments, the transmitter that transmits the sensing signal and the receiver that receives the sensing signal may be included in different devices (e.g., a base station or DU). In a bistatic sensing structure according to embodiments, a first device may transmit a sensing signal, and a second device, different from the first device, may receive the sensing signal reflected from a target. The first device and / or the second device may then perform a sensing operation based on the sensing signal. In this bistatic sensing structure, it is necessary to consider a method for synchronizing the two devices that respectively perform the functions of transmitting and receiving the sensing signal. Various embodiments of the present disclosure are described below based on two synchronized devices. In this disclosure, in a bistatic sensing structure, the device that transmits the sensing signal is referred to as a transmitting (Tx) device or a transmitting role TRP, and the device that receives the sensing signal may be referred to as a receiving (Rx) device or a receiving role TRP. In this disclosure, a sensing mode that follows a bistatic sensing structure may be referred to as a bistatic sensing mode.

[0116] A multi-base sensing structure corresponds to a sensing structure in which multiple transmitting functions and multiple receiving functions for sensing are set in different devices (or locations). The multi-base sensing structure according to an embodiment may be a combination of a single-base and a dual-base sensing structure. For example, a JCAS system using a multi-base sensing structure may include at least one single-base TRP, at least one transmitting role TRP, and at least one receiving role TRP. In the case of a multi-base sensing structure, collaborative sensing using multiple TRPs is feasible, and thereby the robustness of sensing can be ensured. However, in the case of a multi-base sensing structure, more complex synchronization needs to be considered compared to a dual-base sensing structure. Hereinafter, various embodiments of the present disclosure will be described based on the synchronization established between JCAS systems using a multi-base sensing structure. In the present disclosure, a sensing mode that follows a multi-base sensing structure may be referred to as a multi-base sensing mode.

[0117] Reference Figure 4, a JCAS system 400 using a multistatic sensing structure / mode may include a sensing unit (SU) 410, at least one transmitting role TRP 420, at least one receiving role TRP 430, and / or at least one monostatic TRP 440. However, embodiments are not limited thereto, and the type and number of TRPs included in the JCAS system 400 for multistatic sensing may vary.

[0118] The JCAS system 400 according to an embodiment is Figure 3 The example of the JCAS system 300 supports all or some of the functions of the JCAS system 300 and may further support additional functions for multistatic sensing mode.

[0119] Depending on the implementation, the sending role TRP 420, receiving role TRP 430 and single base TRP 440 of the JCAS system 400 fully or partially support the Figure 3 The TRP / base station 320 of the JCAS system 300 supports the functions and may also support additional functions for multi-base sensing mode.

[0120] In a multistatic sensing structure, the sensing unit 410 is a high-level component of the TRP and may designate a role of the TRP according to the type of sensing operation (eg, a monostatic type or a bistatic type).

[0121] According to an embodiment, the sensing unit 410 may designate at least one monostatic TRP 440 for performing a monostatic type sensing operation / mode.

[0122] In the monostatic sensing configuration / mode, the monostatic TRP 440 may transmit a sensing signal, receive a sensing signal reflected from a target (e.g., object 3), and obtain a sensing result and / or sensing data based on the received sensing signal. The monostatic TRP 440 may transmit the sensing result and / or sensing data to the sensing unit 410.

[0123] Depending on the embodiment, the single-base TRP 440 can be a base station level (e.g., gNB level) device or a device at a lower level than the base station (e.g., DU level).

[0124] Depending on the embodiment, the sensing unit 410 may designate at least one transmit role TRP 420 and at least one receive role TRP 430 for performing bistatic sensing operations / modes. As an embodiment, the sensing unit 410 may associate one transmit role TRP 420 with multiple receive role TRPs 430 for bistatic sensing. As an embodiment, the sensing unit 410 may associate multiple transmit role TRPs 420 with one receive role TRP 430 for bistatic sensing.

[0125] In a bistatic sensing configuration / mode, the transmitting role TRP 420 may transmit a sensing signal. The receiving role TRP 430 may receive the sensing signal reflected from a target (e.g., Object 1 and Object 2) and may obtain a sensing result and / or sensing data based on the received sensing signal. The receiving role TRP 430 may transmit the sensing result and / or sensing data to the sensing unit 410.

[0126] Depending on the implementation, the transmit role TRP 420 and the receive role TRP 430 may be base station-level (e.g., gNB-level) devices. In this case, in a bistatic sensing configuration, the base station corresponding to the transmit role TRP 420 (the transmit role base station (e.g., Tx role gNB)) and the base station corresponding to the receive role TRP 430 (the receive role base station (e.g., Rx role gNB)) may be different base stations.

[0127] Depending on the implementation, the transmit role TRP 420 and the receive role TRP 430 may be lower-level (e.g., DU-level) devices of the base station. In this case, in a bistatic sensing configuration, the DU corresponding to the transmit role TRP 420 (transmit role DU) and the DU corresponding to the receive role TRP 430 (receive role DU) may belong to the same base station. For example, the transmit role DU and the receive role DU may be separate DUs controlled / managed by a single CU (e.g., separate DUs located in different locations).

[0128] According to an embodiment, the sensing unit 410 may generate sensing configuration information and notify a designated TRP of the generated sensing configuration information.

[0129] Depending on the embodiment, the sensing unit 410 may receive sensing results from the TRPs and transmit the corresponding sensing results or the combined sensing results to the TRPs. For example, the sensing unit 410 may receive sensing results from the receiving role TRP 430 and transmit the sensing results to the transmitting role TRP 420 associated with the receiving role TRP 430. For example, the sensing unit 410 may receive sensing results from the receiving role TRP 430 and the monostatic TRP 440, respectively, and transmit the combined sensing results to all TRPs.

[0130] The sensing unit 410 according to an embodiment may be a CU. For example, when the transmitting role TRP 420, the receiving role TRP 430, and the mono-base TRP 440 are DUs belonging to the same base station (or CU or gNB), the sensing unit 410 may be a CU that manages / controls the DUs.

[0131] Sensing unit 410, according to an embodiment, may be a higher-level entity than the base station. For example, if transmitting role TRP 420, receiving role TRP 430, and mono-base TRP 440 are base station-level devices, sensing unit 410 may be a higher-level entity of the base station. A higher-level entity of the base station may be an entity of the core network connected to the base station (e.g., an AMF or a newly defined network function (NF)). If a new NF is defined to perform the functions of sensing unit 410, the NF may request the AMF to transmit notifications / reports when necessary.

[0132] The sensing unit 410 according to the embodiment may be a specific base station. For example, if the transmitting role TRP 420, the receiving role TRP 430, and the monobase TRP 440 are base station-level devices, it may be one of the transmitting role TRP 420, the receiving role TRP 430, and the monobase TRP 440.

[0133] Hereinafter, various embodiments of a multi-sensing structure / mode will be described with reference to each of the accompanying drawings. For example, in a multi-base sensing structure / mode, a method for setting the role of a TRP for sensing is described. In addition, a method for generating sensing configuration information for multi-base sensing and providing it to a TRP and / or a UE is described. In addition, a method for transmitting sensing results and / or sensing data from a TRP to a sensing unit is described. In addition, the operation of a UE in a multi-base sensing structure / mode is described.

[0134] [Sensing Program]

[0135] Figure 5A The sensing process in the JCAS system according to an embodiment of the present disclosure is shown.

[0136] Figure 5A An example of a sensing process by a monostatic TRP 440 in a multistatic sensing structure (monostatic sensing process in a multistatic sensing structure) may be illustrated.

[0137] The monostatic sensing process in a multistatic sensing configuration may include at least one of the following operational features: The SU 410 may designate at least one monostatic TRP 440. The SU 410 may allocate resources for sensing.

[0138] The SU 410 may inform the designated monostatic TRP 440 of information on resource allocation for sensing (sensing resource allocation information) together with the role information.

[0139] The single-base TRP 440 may notify the sensing resource allocation information to at least one UE 310. In this case, unlike a general communication system (e.g., Figure 1Unlike the communication system 10), the UE 310 may use the notified sensing resource allocation information to perform an operation different from the existing communication operation in the resource region (or portion) allocated for sensing.

[0140] The monostatic TRP 440 may transmit a sensing signal, receive the sensing signal reflected from a target, and obtain sensing data and / or a sensing result based on the sensing signal.

[0141] The monostatic TRP 440 may transmit sensing data and / or sensing results to the SU 410 .

[0142] In the following, reference Figure 5A An example sensing process in a JCAS system is described.

[0143] Reference Figure 5A , in operation 1, the SU 410 may designate a monostatic TRP 440 for monostatic sensing.

[0144] In addition, SU 410 may perform resource allocation for sensing. For example, SU 410 may allocate time and frequency resources for sensing (or sensing signals). Examples of allocation of time and frequency resources for sensing may be as follows: Figure 6A and Figure 6B According to an embodiment, the sensing resources may not overlap with the communication resources.

[0145] In operation 2, the SU 410 may notify the monostatic TRP 440 of information regarding the role of the monostatic TRP (role information) and information regarding resource allocation for sensing (sensing resource allocation information). Depending on the embodiment, the SU 410 may transmit sensing configuration information including the role information and the sensing resource allocation information to the monostatic TRP 440. The role information may include information indicating that the corresponding TRP is designated as a monostatic TRP.

[0146] In operation 3, the monostatic TRP 440 may notify the UE 310 of the sensing resource allocation information. For example, the monostatic TRP 440 may transmit sensing configuration information including the sensing resource allocation information to the UE 310. As an embodiment, the sensing resource allocation information may include information regarding the time and frequency resources allocated in operation 1 for sensing (or sensing signals). Therefore, the UE 310 may be notified of the current sensing signal allocation status for the sensing signal.

[0147] In operation 4, the monostatic TRP 440 may perform a sensing operation using the resources allocated for sensing (e.g., time and frequency resources). For example, the monostatic TRP 440 may transmit a sensing signal using the time and frequency resources allocated for sensing. As an embodiment, the monostatic TRP 440 may transmit the sensing signal through at least one beam. The monostatic TRP 440 may receive a signal from a target (e.g., Figure 3 The sensing signal (reflected signal) may be reflected by the UE 310 or the target 330 ), and sensing data and / or a sensing result may be obtained based on the reflected signal.

[0148] In operation 5, the UE 310 may determine an operation to be performed using the received / notified information (e.g., sensing resource allocation information, sensing configuration information, etc.). For example, the UE 310 may identify time and frequency resources allocated for sensing based on the sensing resource allocation information, and may perform an operation (e.g., a communication operation and / or a sensing operation) based on the identified time and frequency resources.

[0149] According to an embodiment, the UE 310 may ignore the time and frequency resources allocated for sensing (or signals received through the corresponding resources).

[0150] Depending on the embodiment, UE 310 may perform communication operations using time and frequency resources different from those allocated for sensing. For example, UE 310 may receive communication signals (DL signals) using time and frequency resources allocated for DL ​​communication, rather than the time and frequency resources allocated for sensing. For example, UE 310 may transmit communication signals (UL signals) using time and frequency resources allocated for UL communication, rather than the time and frequency resources allocated for sensing. As an embodiment, information regarding the time and frequency resources allocated for communication may be transmitted from base station 320 to UE 310 via communication configuration information (e.g., PDCCH / DCI).

[0151] According to an embodiment, when the UE 310 supports a sensing function, the UE 310 may receive a sensing signal using time and frequency resources allocated for sensing, and may perform a sensing operation based on the received sensing signal. The UE 310 may perform a sensing operation to obtain sensing data and / or sensing results.

[0152] In operation 6, the monostatic TRP 440 may transmit a report (sensing result report) including sensing data and / or sensing results to the SU 410. As an embodiment, when the cooperative sensing mode is applied, the monostatic TRP 440 may transmit the sensing result report to the SU 410.

[0153] Meanwhile, according to the embodiment, some operations in the above operations 1 to 6 may be omitted, and / or additional operations may be further performed. In addition, the operations may be performed in an order different from the order shown / described, or multiple operations may be performed simultaneously.

[0154] At the same time, Figure 5A In the description, for ease of description, the process between a base station / TRP and a UE has been described as an example, but the embodiment is not limited thereto. For example, multiple UEs may be connected to a TRP. In this case, each UE may perform the same process between the TRP and the UE as described above with the corresponding TRP.

[0155] Figure 5B The sensing process in the JCAS system according to an embodiment of the present disclosure is shown.

[0156] Figure 5B An example of a sensing process by the transmitting role TRP 420 and the receiving role TRP 430 in a multistatic sensing structure (a bistatic sensing process in a multistatic sensing structure) may be shown.

[0157] The bistatic sensing process in a multistatic sensing configuration may include at least one of the following operational features: The SU 410 may designate at least one transmit role TRP 420 and at least one receive role TRP 430. The SU 410 may allocate resources for sensing.

[0158] The SU 410 may notify the designated transmitting role TRP 420 and receiving role TRP 430 of information on resource allocation for sensing (sensing resource allocation information) together with the role information.

[0159] The transmitting role TRP 420 and the receiving role TRP 430 may inform each of at least one related UE 310a and UE 310b of the sensing resource allocation information. In this case, unlike a general communication system (e.g., Figure 1 Unlike the communication system 10), the UE 310a and the UE 310b can use the notified sensing resource allocation information to perform operations different from the existing communication operations in the resource region (or part) allocated for sensing. The first UE 310a and the second UE 310b can perform Figure 3 In the present disclosure, the first UE 310a and the second UE 310b may be collectively referred to as UE 310.

[0160] The transmitting role TRP 420 may transmit a sensing signal.

[0161] The receiving role TRP 430 may receive a sensing signal reflected from a target and obtain sensing data and / or a sensing result based on the sensing signal.

[0162] The receiving role TRP 430 may transmit sensing data and / or sensing results to the SU 410 .

[0163] The SU 410 may transmit the sensing data and / or the sensing result to the transmitting role TRP 420 .

[0164] In the following, reference Figure 5B An example sensing process in a JCAS system is described.

[0165] Reference Figure 5B , in operation 1, the SU 410 may designate a transmit role TRP 420 and a receive role TRP 430 for bistatic sensing.

[0166] In addition, the SU 410 may perform resource allocation for sensing. For example, the SU 410 may allocate time and frequency resources for sensing (or sensing signals). Resource allocation for sensing (eg, time / frequency resource allocation) may be performed. Examples of allocation of time and frequency resources for sensing may include: Figure 6A and Figure 6B According to an embodiment, the sensing resources may not overlap with the communication resources.

[0167] In operation 2, the SU 410 may notify the transmitting role TRP 420 and the receiving role TRP 430 of information regarding the role of the bistatic TRP (role information) and information regarding resource allocation for sensing (sensing resource allocation information). Depending on the embodiment, the SU 410 may transmit sensing configuration information including the role information and the sensing resource allocation information to the transmitting role TRP 420 and the receiving role TRP 430. The role information may include information indicating that the corresponding TRP is designated as the transmitting role TRP or the receiving role TRP for bistatic sensing.

[0168] In operation 3, the transmitting role TRP 410 and the receiving role TRP 420 may transmit sensing resource allocation information to at least one UE 310a and UE 310b respectively associated therewith.

[0169] For example, the transmitting role TRP 410 may transmit sensing configuration information including sensing resource allocation information to at least one first UE 310a connected to the transmitting role TRP 410, and the receiving role TRP 420 may transmit sensing configuration information including sensing resource allocation information to at least one second UE 310b connected to the receiving role TRP 420.

[0170] As an embodiment, the sensing resource allocation information may include information about the time and frequency resources allocated for sensing (or sensing signals) in operation 1. Therefore, the current resource allocation state of the sensing signal may be notified to the UE 310. In the present disclosure, the sensing resource allocation information may be referred to as sensing resource allocation state information.

[0171] In operation 4, the transmitting role TRP 420 and the receiving role TRP 430 may perform a sensing operation using resources allocated for sensing (eg, time and frequency resources).

[0172] According to an embodiment, the transmission role TRP 420 may transmit the sensing signal using time and frequency resources allocated for sensing. In an embodiment, the transmission role TRP 420 may transmit the sensing signal through at least one beam.

[0173] According to an embodiment, the receiving role TRP 430 may receive the data from the target (e.g. Figure 3 UE 310, Figure 4 UE 310a and UE 310b, or Figure 3 According to an embodiment, the receiving role TRP 420 may receive the sensing signal through at least one beam.

[0174] In operation 5, UE 310a and UE 310b may use the received / notified information (e.g., sensing resource allocation information, sensing configuration information, etc.) to determine the operation to be performed. For example, UE 310a and UE 310b may identify the time and frequency resources allocated for sensing based on the sensing resource allocation information, and perform an operation (e.g., a communication operation and / or a sensing operation) based on the identified time and frequency resources. UE 310a and UE 310b may perform Figure 3 All or some of the functions supported by the UE 300.

[0175] According to an embodiment, UE 310a and UE 310b may ignore the time and frequency resources allocated for sensing (or signals received through the corresponding resources).

[0176] Depending on the embodiment, UE 310a and UE 310b may perform communication operations using time and frequency resources different from the time and frequency resources allocated for sensing. For example, UE 310a and UE 310b may receive communication signals (DL signals) using time and frequency resources allocated for DL ​​communication instead of the time and frequency resources allocated for sensing. For example, UE 310a and UE 310b may transmit communication signals (UL signals) using time and frequency resources allocated for UL communication instead of the time and frequency resources allocated for sensing. In an embodiment, information regarding the time and frequency resources allocated for communication may be transmitted from transmit role TRP 420 and receive role TRP 430 to UE 310a and UE 310b via communication configuration information (e.g., PDCCH / DCI).

[0177] According to an embodiment, when UE 310a and UE 310b support a sensing function, UE 310a and UE 310b may use the time and frequency resources allocated for sensing to receive a sensing signal and perform a sensing operation based on the received sensing signal. UE 310a and UE 310b may perform a sensing operation to obtain sensing data and / or sensing results.

[0178] In operation 6, the receiving role TRP 430 may transmit a report (sensing result report) including the sensing result and / or sensing data to the SU 410. As an embodiment, the receiving role TRP 430 may send the sensing result report to the SU 410 regardless of whether the sensing mode is the collaborative sensing mode.

[0179] In operation 7 , the sensing result report of the SU 410 may be transmitted to the receiving role TRP 420 .

[0180] Meanwhile, according to the embodiment, some operations in the above operations 1 to 6 may be omitted, and / or additional operations may be further performed. In addition, the operations may be performed in an order different from the order shown / described, or multiple operations may be performed simultaneously.

[0181] At the same time, Figure 5B In the description, for ease of description, the process between a base station / TRP and a UE has been described as an example, but the implementation is not limited thereto. For example, multiple UEs may be connected to a TRP base station. In this case, each UE may perform the same process between the TRP and the UE as described above with the corresponding TRP.

[0182] [Allocation of Sensing Resources]

[0183] Figure 6A and Figure 6BAn example of resource allocation for sensing according to an embodiment of the present disclosure is shown.

[0184] exist Figure 6A and Figure 6B In the embodiment, for the convenience of description, it is assumed that the time-frequency domain structure follows Figure 2A The time-frequency domain structure of the frame, subframe and time slot follows Figure 2B Frame, subframe and time slot structure, but the implementation is not limited thereto.

[0185] As an implementation, in the time domain, at least one OFDM symbol may be allocated for sensing. Figure 6A As shown, the first OFDM symbol (e.g., the sixth OFDM symbol (symbol index = 5)) in a first time slot (e.g., the first time slot (1st time slot) of a frame or cycle) and the second OFDM symbol (e.g., the sixth OFDM symbol (symbol index = 5)) in a second time slot after the first time slot (e.g., the second time slot (2nd time slot) of a frame or cycle) can be allocated for sensing.

[0186] As an embodiment, in the time domain, symbols for sensing (sensing symbols) may be allocated at predetermined intervals. For this purpose, the interval between adjacent OFDM symbols for sensing may be set by the base station 320 (or the transmitting role TRP 410 or the CU). ). Therefore, OFDM symbols for sensing can be allocated in the time domain at the same interval.

[0187] As an embodiment, in the time domain, OFDM symbols and / or time slots corresponding to a predetermined number (or duration) for Doppler processing may be allocated. To this end, the number of time slots used for Doppler processing or the duration of the accumulated symbols (OFDM symbols) used for Doppler processing ( ) can be set by the base station 320 (or the transmitting role TRP 410 or CU). Figure 6B As shown, a predetermined number of OFDM symbols in the time domain may be allocated for sensing. As an embodiment, the duration ( ) can be associated with the number of symbols used for Doppler processing.

[0188] As an embodiment, the base station 320 (or the transmitting role TRP 410 or the CU) may set an interval for Doppler processing ( ), number of time slots and / or duration ( For example, the base station 320 (or the transmitting role TRP 410 or the CU) may be based on the interval for Doppler processing ( ), number of time slots and / or duration ( ) to allocate OFDM symbols for sensing in the time domain. The base station 320 (or the transmitting role TRP 410 or the CU) may send information about the time resources allocated for sensing (sensing time resource information) to the UE 310. As an embodiment, the sensing time resource information may include an interval ( ), the number of time slots used for Doppler processing, the number of symbols used for Doppler processing, or the duration ( ). Therefore, the OFDM symbol allocation state for sensing may be notified to the UE 310. The UE 310 may perform an operation based on the notified information. Meanwhile, the duration ( ) is information sufficient for a receiving device (eg, base station 320) that senses a signal to know, and the duration may not be notified to UE 310.

[0189] As an embodiment, in the frequency domain, all or some of the subcarriers of the OFDM symbol allocated for sensing may be allocated for sensing. Figure 6A As shown, all of the subcarriers associated with the OFDM symbol allocated for sensing may be allocated for sensing. Figure 5A / Figure 5B As shown, some of the subcarriers associated with the OFDM symbols allocated for sensing may be allocated for sensing. In this case, the allocated subcarriers may be consecutive subcarriers.

[0190] [Interference Management]

[0191] In the case of a multi-base sensing structure, interference may occur between TRPs depending on the sensing operation. For example, interference may occur when multiple TRPs use the same sensing resources (e.g., time / frequency resources) to transmit sensing signals.

[0192] Figure 7A is a view illustrating an example of interference generated in a multistatic sensing structure according to an embodiment of the present disclosure.

[0193] Figure 7A An example of interference occurring when multiple transmit roles TRPs are configured for bistatic sensing in a multistatic sensing structure may be shown.

[0194] exist Figure 7A In the embodiment, it is assumed that the first sending TRP 420a and the first receiving TRP 430a are associated with each other, and the second sending TRP 420b and the second receiving TRP 430b are associated with each other.

[0195] Reference Figure 7A, each of the receiving role TRP 430a and the receiving role TRP 430b can receive sensing signals transmitted from multiple transmitting role TRPs 420a and 420b together (or simultaneously). In this case, when the first sensing signal transmitted from the first TRP 420b and the second sensing signal transmitted from the first TRP 420b are allocated to the same sensing resources (time / frequency resources), the sensing signals transmitted from the unrelated transmitting TRPs may interfere with the corresponding receiving TRPs. For example, the second sensing signal of the second transmitting TRP 420b transmitted via the same sensing resource as the first sensing signal of the first transmitting TRP 420a may interfere with the first receiving TRP 430a. In addition, when the first sensing signal and the second sensing signal are not distinguished, the bistatic sensing operation may also be affected.

[0196] Figure 7B is a view illustrating an example of interference generated in a multistatic sensing structure according to an embodiment of the present disclosure.

[0197] Figure 7B An example of interference between a transmit role TRP and a monostatic TRP for bistatic sensing in a multistatic sensing structure may be shown.

[0198] Reference Figure 7B , the monostatic TRP 440 may receive the sensing signal transmitted from the transmitting role TRP 420 together with (or simultaneously with) the sensing signal transmitted by itself. In this case, if the sensing signal transmitted from the transmitting role TRP 420 and its own sensing signal are allocated to the same sensing resource (time / frequency resource), the sensing signal transmitted from the transmitting role TRP 420 may interfere with the monostatic TRP 440.

[0199] The receiving role TRP 430 may receive the sensing signal transmitted from the monostatic TRP 440 together with (or simultaneously with) the sensing signal transmitted from the transmitting role TRP 420. In this case, when the sensing signal transmitted from the transmitting role TRP 420 and the sensing signal transmitted from the monostatic TRP 440 are allocated to the same sensing resource (time / frequency resource), the sensing signal transmitted from the monostatic TRP 440 may interfere with the receiving role TRP 430.

[0200] Figure 7C An example of sensing resource allocation for interference removal according to an embodiment of the present disclosure is shown.

[0201] Figure 7C An embodiment may be an embodiment of allocating non-overlapping sensing resources to each TRP (eg, transmitting role TRP, monostatic TRP) that transmits a sensing signal to remove interference in a multistatic sensing structure / mode.

[0202] According to an embodiment, sensing resource allocation may be performed by the SU for each TRP.

[0203] According to an embodiment, the allocation of sensing resources for each transmitted TRP may be performed at the time domain / frequency domain level. As an embodiment, the allocation information (e.g., Figure 8D time domain allocation information) and / or frequency domain allocation information (e.g., Figure 8D frequency domain allocation information) to perform resource allocation at the time domain / frequency domain level.

[0204] Depending on the embodiment, the allocation of sensing resources for each transmit TRP may be performed at a slot level with different offsets (slot offsets). Figure 7C As shown, the sensing resources for the first transmission role TRP (transmission role TRP 1) can be allocated with a first time slot offset (time slot offset 1), and the sensing resources for the first transmission role TRP (transmission role TRP2) can be allocated with a second time slot offset (time slot offset 0). Therefore, time slots that do not overlap with each other can be allocated to each transmission TRP. As an embodiment, the time slot repetition period information (e.g., Figure 8D time slot repetition period information) and / or time slot offset information (e.g., Figure 8D time slot offset information) to perform time slot level resource allocation.

[0205] According to an embodiment, the SU may transmit information about sensing resource allocation set for each transmission TRP to the TRP (eg, a transmission role TRP, a reception role TRP, and a monostatic TRP).

[0206] According to an embodiment, each TRP may transmit information about the sensing resource allocation set for each transmitting TRP to each of at least one UE. Thus, the UE may identify the sensing resources configured / allocated for each transmitting TRP and perform operations based on the sensing resources.

[0207] On the other hand, as in Figure 7C In an embodiment, when sensing resources are allocated separately for each transmitted TRP to remove interference, sensing overhead may increase and communication resources may decrease.

[0208] Figure 7D An example of sensing resource allocation for interference removal according to an embodiment of the present disclosure is shown.

[0209] Figure 7DAn embodiment may be one in which a different sensing sequence is assigned to each TRP (transmitting TRP) (e.g., a transmitting role TRP, a monostatic TRP) that transmits a sensing signal to eliminate interference in a multistatic sensing structure / mode. In this case, multiple TRPs can perform sensing operations using the same sensing resources without interference.

[0210] According to an embodiment, the sequence allocation and sensing resource allocation for each TRP may be performed by the SU. According to an embodiment, the SU may use the sensing configuration information (e.g., Figure 8D The sensing configuration information) provides each TRP with information on sequence allocation and sensing resource allocation for each TRP.

[0211] According to an embodiment, the sequence allocated to each TRP may be generated based on a pseudo-random noise (PN) sequence or an orthogonal sequence.

[0212] Reference Figure 7D , the same sensing resources can be allocated to multiple TRPs. For example, as shown in the figure, the same time / frequency resources can be allocated as sensing resources for the first transmission role TRP (transmission role TRP 1), the second transmission role TRP (transmission role TRP 2), and the monobase TRP. In this case, a different sensing sequence can be configured for each of the first transmission role TRP, the second transmission role TRP, and the monobase TRP. For example, as shown in the figure, a first sequence can be configured for the first transmission role TRP, a second sequence can be configured for the second transmission role TRP, and a third sequence can be configured for the monobase TRP.

[0213] According to an embodiment, each of the first transmission role TRP, the second transmission role TRP and the monobase TRP may transmit a sensing signal in the same sensing resource using its own sequence.

[0214] According to an embodiment, the SU may send sequence information to the TRPs (e.g., the transmitting role TRP, the receiving role TRP, and the mono-base TRP). The sequence information may include information about the sequence configured for the first transmitting role TRP, the sequence configured for the second transmitting role TRP, and / or the sequence configured for the mono-base TRP. The sequence information may be, for example Figure 8D The sequence information is in the form of

[0215] A receiving TRP (e.g., a receiving role TRP and a monostatic TRP) that receives a sensing signal according to an embodiment may receive the sensing signal using the sensing resources allocated for sensing. For example, the receiving TRP may receive a sensing signal transmitted from a first transmitting role TRP, a sensing signal transmitted from a second transmitting role TRP, and a sensing signal transmitted from a monostatic TRP using the same sensing resources allocated for sensing.

[0216] According to an embodiment, the receiving TRP can distinguish each received sensing signal based on the received sequence information. For example, the receiving TRP can separate the sensing signal transmitted from the first transmitting role TRP, the sensing signal transmitted from the second transmitting role TRP, and the sensing signal transmitted from the monostatic TRP based on the received sequence information. Therefore, the receiving TRP can perform the sensing operation without interference.

[0217] [Sensor configuration information]

[0218] Hereinafter, the configuration of the information for the configuration of sensing (sensing configuration information) is described. Figures 8A to 8D and Figure 11 The parameters in the sensing configuration information can be combined, changed or replaced with each other as long as they do not contradict each other.

[0219] According to an embodiment, the sensing configuration information may be used for SU-TRP notification. According to an embodiment, the sensing configuration information may be used for TRP-UE notification.

[0220] Figure 8A An example of sensing configuration information according to an embodiment of the present disclosure is shown.

[0221] exist Figure 8A In an embodiment, the sensing configuration information may have a hierarchical structure.

[0222] Reference Figure 8A , the sensing configuration information may include at least one piece of sensing resource configuration information (eg, Sensing-ResourceConfig).

[0223] The sensing resource configuration information may include resource configuration ID information (eg, ResourceConfigID), transmission mode information (eg, transmission mode), and / or at least one sensing resource set information (eg, SensingResourceSet #1, SensingResourceSet #2, etc.).

[0224] The resource configuration ID information may indicate an ID of the sensing resource configuration information.

[0225] The transmission mode information may indicate the transmission mode of the sensing signal (or sensing sequence) in the sensing configuration applied by the sensing resource configuration information. As an embodiment, the transmission mode may be one of a periodic transmission mode, a semi-persistent transmission mode, and an aperiodic transmission mode. As an embodiment, the multistatic sensing structure / mode may be limited to using only the periodic transmission mode. In this case, the transmission mode information may not be included in the sensing configuration information (or sensing resource configuration information).

[0226] As an embodiment, the resource configuration ID information and transmission mode information may be information at the sensing resource configuration information level, which is a higher level than the sensing resource set information level. A separate resource configuration ID (or sensing resource configuration information identified by a resource configuration ID) may be assigned to each transmission mode indicated by the transmission mode information. For example, the resource configuration ID of the sensing resource configuration information for a periodic transmission mode may be different from the resource configuration ID of the sensing resource configuration information for an aperiodic transmission mode. As described above, by configuring the resource configuration ID information and transmission mode information as the highest level of the sensing resource configuration information, separate sensing resource set information / sensing resource information may be configured for each transmission mode.

[0227] The sensing resource set information may include at least one piece of sensing resource information (eg, SensingResource #1 and SensingResource #2).

[0228] The sensing resource set information may also include sensing resource set information level information that varies depending on the transmission mode. For example, when the transmission mode is a semi-persistent transmission mode, the sensing resource set information may include trigger information (semi-persistent start trigger) for starting the semi-persistent transmission mode for the corresponding sensing resource set (e.g., SensingResourceSet #1) and / or trigger information (semi-persistent stop trigger) for stopping the semi-persistent transmission mode. For example, when the transmission mode is an aperiodic transmission mode, the sensing resource set information may include trigger information (aperiodic start trigger) and / or offset information (aperiodic offset) for starting the aperiodic transmission mode for the corresponding sensing resource set (e.g., SensingResourceSet #1). The sensing resource set information level may be a higher level than the sensing resource information level.

[0229] Sensing resource information may include information about sensing resources according to sensing requirements or application requirements. As an embodiment, multiple sensing resource information configured for each sensing requirement (or application) may be included in one piece of sensing resource set information. For example, SensingResource #1 configured according to a first sensing requirement (or first application) and SensingResource #2 configured according to a second sensing requirement (or second application) may be included in one piece of sensing resource set information (e.g., SensingResourceSet #1). As an embodiment, multiple sensing resource set information configured for each sensing requirement (or first application) may be included in one piece of sensing resource configuration information. For example, SensingResourceSet #1 configured according to a first sensing requirement (or first application) and SensingResourceSet #2 configured according to a second sensing requirement (or second application) may be included in one piece of sensing resource configuration information.

[0230] Sensing resource information, depending on the embodiment, may include information regarding the structure of the sensing signal, information regarding the waveform type, information used for measurement range, and / or information used for Doppler processing. As an embodiment, the information used for measurement range may include frequency resource allocation information for sensing. As an embodiment, the information used for Doppler processing may include time resource allocation information for sensing, information regarding the period for transmitting the sensing signal, information regarding the offset for transmitting the sensing signal (e.g., time slot offset), and / or information regarding the number of symbols required for Doppler processing (symbol count information used for Doppler processing). As an embodiment, when the same waveform is used for sensing and communication, information regarding the waveform type may not be included in the sensing resource information.

[0231] According to an embodiment, the SU 410 may transmit the sensing configuration information to the transmitting role TRP 420 , the receiving role TRP 430 , and / or the monostatic TRP 440 using a pre-configured interface (eg, an F1 interface or an X2 interface).

[0232] According to an embodiment, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430 or the monostatic TRP 440) may send the sensing configuration information to the UE 310 through higher layer signaling and / or PHY layer signaling.

[0233] For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, or the monobase TRP 440) may transmit the sensing configuration information via a radio resource control (RRC) message as higher layer signaling. As an embodiment, the RRC message may include all or part of the information included in the sensing configuration information.

[0234] For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, or the monostatic TRP 440) may transmit the sensing configuration information using system information (eg, SIB) as higher layer signaling. As an embodiment, the SIB may include part of the information included in the sensing configuration information.

[0235] For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, or the monostatic TRP 440) may use a MAC control element (CE) as higher layer signaling to transmit the sensing configuration information. As an embodiment, the MAC CE may include all or part of the information included in the sensing configuration information.

[0236] For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, or the monostatic TRP 440) may transmit the sensing configuration information via DCI as PHY layer signaling. As an embodiment, the DCI may include all or part of the information included in the sensing configuration information.

[0237] Figure 8B An example of sensing configuration information according to an embodiment is shown.

[0238] Figure 8B The sensing configuration information can be used for periodic transmission mode.

[0239] Figure 8B The sensing configuration information may be used for a TRP (eg, a transmitting role TRP 420, a receiving role TRP 430, or a mono-base TRP 440) to transmit the sensing configuration to the UE, but is not limited thereto.

[0240] Reference Figure 8B , the sensing configuration information may be in the form of a predefined table. For example, Figure 9B The configuration table for the sensing parameter set of the table may be predefined. In the table, the setting values ​​of the sensing parameters included in the sensing parameter set may be set to be different for each set ID indicated by the set ID information. For example, Figure 8B As shown, setting values ​​of sensing parameters included in a sensing parameter set for a first set ID (set ID=1) may be different from setting values ​​of sensing parameters included in a sensing parameter set for a second set ID (set ID=2).

[0241] As an embodiment, the sensing parameter set may include at least one sensing parameter. Figure 8BAs shown, the sensing parameter set may include a slot repetition period parameter / information, a slot offset parameter / information, an OFDM symbol index parameter / information, a start RE index parameter / information, an end RE index parameter / information, a sensing waveform parameter / information and / or a symbol count parameter / information for Doppler processing for each time slot.

[0242] Slot repetition period information, slot offset, and OFDM symbol index information for each slot may be used for time resource allocation for sensing.

[0243] The slot repetition period information may specify the period (slot repetition period) allocated to OFDM symbols (sensing symbols) for transmitting a sensing sequence (or sensing data). As an embodiment, the slot repetition period information may indicate the period in which the sensing symbols are allocated as a number of slots. In this disclosure, the slot repetition period information may be referred to as repetition period information or period information.

[0244] The time slot offset information may specify an offset from the start time of the period specified by the time slot repetition period information to the start time of the time slot to which the sensing symbol is assigned (sensing time slot). As an embodiment, the time slot offset information may specify the offset on a per-time slot basis. In the present disclosure, the time slot offset information may be referred to as offset information.

[0245] The OFDM symbol index information for each time slot may specify the index of the OFDM symbol corresponding to the sensing symbol in each time slot to which the sensing symbol is allocated. When multiple sensing symbols are allocated in the corresponding time slot, the OFDM symbol index information for each time slot may specify the OFDM symbol index for each of the multiple sensing symbols. In the present disclosure, the OFDM symbol index information for each time slot may be referred to as sensing symbol index information.

[0246] The start RE index information and the end RE index information may be used for frequency resource allocation for sensing.

[0247] The start RE index information may specify the index of the start RE for contiguous frequency allocation. The end RE index information may specify the index of the end RE for contiguous frequency allocation. The contiguous frequency resources specified by the start RE index information and the end RE index information may be used for sensing.

[0248] The sensing waveform information may specify the type of waveform used for sensing (or sensing operation). For example, the sensing waveform information may be one-bit information set to a first value (e.g., 0) indicating that the waveform type is an FMCW-based waveform or a second value (e.g., 1) indicating that the waveform type is an OFDM-based waveform.

[0249] The number of symbols used for Doppler processing may specify the number of accumulated symbols (OFDM symbols) required for Doppler processing (eg, 32, 64, 128, 256).

[0250] As an embodiment, for each value of the set ID in Table 9B, the setting values ​​of the parameters included in the sensing parameter set can be fixed values ​​(e.g., values ​​defined in a standard) or pre-shared values ​​among sensing devices. Therefore, sensing devices (e.g., base station 320, UE 310, SU 410, transmit role TRP 420, receive role TRP 430, and monostatic TRP 440) can pre-know the setting values ​​of the parameters included in the sensing parameter set for each value of the set ID (e.g., the table values ​​in Table 9B). Therefore, base station 320 (or transmit role TRP 420, receive role TRP 430, and monostatic TRP 440) can simply transmit (or broadcast) the value of the set ID information to UE 310, which will serve as sensing configuration information for sensing resource allocation. This reduces signaling overhead. In this case, UE 310 can obtain the setting values ​​of the parameters included in the sensing parameter set corresponding to the set ID based on the set ID in the set ID information and can perform operations (e.g., communication operations and / or sensing operations) based on the setting values.

[0251] According to an embodiment, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440) may transmit set ID information (or sensing configuration information including set ID information) to the UE 310 via higher layer signaling (e.g., SIB, RRC message, and / or MAC CE) or PHY layer signaling (e.g., DCI). For example, the base station 320 (the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440) may broadcast an SIB including set ID information. For example, the base station 320, the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440 may transmit an RRC message including set ID information to the UE 310. For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440) may transmit a MAC CE including set ID information to the UE 310. For example, the base station 320 (or the transmitting role TRP 420 , the receiving role TRP 430 , and the monobase TRP 440 ) may transmit a DCI including set ID information to the UE 310 .

[0252] According to an embodiment, the SU 410 may transmit the set ID information to the transmitting role TRP 420, the receiving role TRP 430, and / or the monostatic TRP 440 using a predefined interface (eg, an F1 interface, an X2 interface).

[0253] Figure 8C An example of sensing configuration information for a periodic transmission mode according to an embodiment is shown.

[0254] Figure 8C The sensing configuration information can be used for periodic transmission mode.

[0255] Figure 8C The sensing configuration information may be used by a TRP (eg, a transmitting role TRP 420, a receiving role TRP 430, or a mono-base TRP 430) to convey the sensing configuration to the UE, but the present disclosure is not limited thereto.

[0256] Reference Figure 8C The sensing configuration information may be in the form of a bitmap. For example, the configuration of the sensing parameter set may be configured in the form of a bitmap.

[0257] As an embodiment, the sensing parameter set may include at least one sensing parameter. Figure 8C As shown, the sensing parameter set may include time slot repetition period parameters / information, time slot offset parameters / information, time domain allocation parameters / information, frequency domain allocation parameters / information, sensing waveform parameters / information and / or symbol count parameters / information for Doppler processing.

[0258] The slot repetition period information, slot offset, and time domain allocation information may be used for time resource allocation for sensing.

[0259] The slot repetition period information may specify the period (slot repetition period) of OFDM symbols (sensing symbols) to which the sensing sequence (or sensing data) is assigned. As an embodiment, the slot repetition period information may indicate the period over which the sensing symbols are assigned, corresponding to the number of slots. As an embodiment, the slot repetition period information may be set to a two-bit value specifying the period (e.g., 1, 2, 4, or 8) to which the sensing symbols are assigned.

[0260] The slot offset information may specify an offset from the start time of the period specified by the slot repetition period information to the start time of the time slot to which the sensing symbol is assigned. As an embodiment, the slot offset information may specify the offset on a per-slot basis. As an embodiment, the slot offset information may be set to a two-bit value specifying the slot offset (e.g., 0, 1, 2, 3).

[0261] The time domain allocation information may be set to one of predefined values ​​to specify the index of the OFDM symbol corresponding to the sensing symbol in each time slot to which the sensing symbol is allocated. For example, the time domain allocation information may be one-bit information set to one of a first value (e.g., 0) indicating that one OFDM symbol is allocated as the sensing symbol in the corresponding time slot, or a second value (e.g., 1) indicating that two OFDM symbols are allocated as the sensing symbol in the corresponding time slot.

[0262] When the time domain allocation information is set to a first value (eg, 0) (indicating that one OFDM symbol is allocated as a sensing symbol), a value of an OFDM symbol index of a corresponding sensing symbol may be a predetermined value (eg, an OFDM symbol index value corresponding to the eighth OFDM symbol).

[0263] When the time domain allocation information is set to a second value (e.g., 1) (indicating that two OFDM symbols are allocated as sensing symbols), the values ​​of the OFDM symbol indexes of the corresponding two sensing symbols may be predetermined values ​​(e.g., an OFDM symbol index value corresponding to the first OFDM symbol and an OFDM symbol index value corresponding to the eighth OFDM symbol).

[0264] The frequency domain allocation information may include information for continuous frequency allocation. As an embodiment, the frequency domain allocation information may be one-bit information set to one of a first value (e.g., 0) indicating the entire bandwidth available / configurable in the base station (e.g., all RBs (e.g., the total system bandwidth)) or a second value (e.g., 1) indicating half the bandwidth of all RBs available / configurable in the base station (e.g., the first half of the RBs (e.g., the first half of the total system bandwidth)).

[0265] The sensing waveform information may specify the type of waveform used for sensing (or sensing operation). For example, the sensing waveform information may be one-bit information set to a first value (e.g., 0) indicating that the waveform type is an FMCW-based waveform or a second value (e.g., 1) indicating that the waveform type is an OFDM-based waveform.

[0266] The number of symbols used for Doppler processing may specify the number of accumulated symbols (OFDM symbols) required for Doppler processing (e.g., 32, 64, 128, 256). For example, the symbol count information used for Doppler processing may be two-bit information set to one of a first value (e.g., 0) indicating that the number of accumulated symbols required for Doppler processing is 32, a second value (e.g., 1) indicating that the number of accumulated symbols required for Doppler processing is 64, a third value (e.g., 2) indicating that the number of accumulated symbols required for Doppler processing is 128, and a fourth value (e.g., 3) indicating that the number of accumulated symbols required for Doppler processing is 256.

[0267] As an embodiment, the bitmap of the sensing parameter set can be set to a total of 9 bits. Figure 8C As shown, among the 9 bits, the two least significant bits (LSBs) can be used to set the time slot repetition period information, the next two bits can be used to set the time slot offset information, the next bit can be used to set the time domain allocation information, the next bit can be used to set the frequency domain allocation information, the next bit can be used to set the sensing waveform information, and the two most significant bits (MSBs) can be used to set the symbol count information for Doppler processing. However, this is merely an example of a bitmap of a sensing parameter set, and embodiments are not limited thereto.

[0268] For example, the parameters (information) of the sensing parameter set can also be used to Figure 8C The order shown varies depending on the order in which the bitmaps are configured.

[0269] For example, some parameters (information) in the sensing parameter set may be omitted, or a bitmap further including additional parameters (information) may be used. In this case, the length of the bitmap may be longer or shorter than 9 bits.

[0270] Depending on the embodiment, the type and order of the parameters (information) included in the sensing parameter set configured in the form of a bitmap, as well as the bitmap length, can be fixed values ​​(e.g., values ​​defined in the standard), or can be values ​​previously shared among devices used for sensing. Therefore, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, and the monobase TRP 440) can simply transmit (or broadcast) the bitmap of the sensing parameter set (sensing parameter bitmap) to the UE 310 for sensing resource allocation. This reduces signaling overhead. In this case, the UE 310 can obtain the setting values ​​of the parameters included in the sensing parameter set corresponding to the sensing parameter bitmap based on the setting values ​​of the sensing parameter bitmap, and can perform operations (e.g., communication operations and / or sensing operations) based on the setting values.

[0271] According to an embodiment, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, or the monostatic TRP 440) may transmit a sensing parameter bitmap (or sensing configuration information including the sensing parameter bitmap) to the UE 310 via higher layer signaling (e.g., SIB, RRC message, and / or MAC CE) or PHY layer signaling (e.g., DCI). For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440) may broadcast an SIB including the sensing parameter bitmap. For example, the base station 320, the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440 may transmit an RRC message including the sensing parameter bitmap to the UE 310. For example, the base station 320 (or the transmitting role TRP 420, the receiving role TRP 430, and the monostatic TRP 440) may transmit a MAC CE including the sensing parameter bitmap to the UE 310. For example, the base station 320 (or the transmitting role TRP 420 , the receiving role TRP 430 , and the monostatic TRP 440 ) may transmit a DCI including a sensing parameter bitmap to the UE 310 .

[0272] According to an embodiment, the SU 410 may transmit the sensing parameter bitmap to the transmitting role TRP 420 , the receiving role TRP 430 , and / or the monostatic TRP 440 using a pre-configured interface (eg, an F1 interface or an X2 interface).

[0273] at the same time, Figure 8B The sensing parameters in the sensing parameter set and Figure 8C The sensing parameters in the sensing parameter set can be combined or replaced with each other.

[0274] For example, Figure 8C Some or all of the parameters in the set of sensing parameters may be used with Figure 8B Some or all of the parameters in the sensing parameter set together with, or instead of Figure 8B Some or all of the parameters in the sensing parameter set are used to configure Figure 8B Configuration table. For example, Figure 8B Some or all of the parameters in the set of sensing parameters may be used with Figure 8C Some or all of the parameters in the sensing parameter set together with, or instead of Figure 8C Some or all of the parameters in the sensing parameter set are used to configure Figure 8C The sensing parameter bitmap.

[0275] For example, Figure 8B The sensing symbol index information (OFDM symbol index for each time slot) can be obtained by Figure 8CThe time domain allocation information of is used instead of, or vice versa. For example, Figure 8B The start RE index information and end RE index information can be obtained by Figure 8C The frequency domain allocation information is used instead of, or vice versa.

[0276] Figure 8D An example of sensing configuration information according to an embodiment is shown.

[0277] Figure 8D The sensing configuration information may be an example of sensing configuration information for a multistatic sensing structure / mode.

[0278] Figure 8D The sensing configuration information can be used to transmit the sensing configuration to the sending role TRP 420, the receiving role TRP 430 or the single base TRP 440.

[0279] Reference Figure 8D The sensing configuration information may include at least one sensing parameter field / information. For example, the sensing configuration information may include role indicator information, TRP ID information, associated bistatic transmission (Tx) TRP information, sequence information, time slot repetition period information, time slot offset information, time domain allocation information, frequency domain allocation information, sensing waveform information, and / or symbol count information for Doppler processing.

[0280] The role indicator information may be used to specify the role of a TRP. As an embodiment, the role indicator information may include single base indicator information, transmitting role indicator information, and / or receiving role indicator information. As an embodiment, the role indicator information may be set for each TRP.

[0281] The monostatic indicator information may indicate whether the TRP is a monostatic TRP. As an embodiment, the monostatic indicator information may be set to a first value (eg, 0) indicating that the corresponding TRP is a monostatic TRP or a second value (eg, 1) indicating that the corresponding TRP is not a monostatic TRP.

[0282] The transmission role indicator information may indicate whether the TRP is a TRP that performs a transmission role (transmission role TRP). As an embodiment, the transmission role indicator information may be set to a first value (e.g., 0) indicating that the corresponding TRP is a transmission role TRP or a second value (e.g., 1) indicating that the corresponding TRP is not a transmission role TRP.

[0283] The receiving role indicator information may indicate whether the corresponding TRP is a TRP that performs a receiving role (receiving role TRP). As an embodiment, the receiving role indicator information may be set to one of a first value (e.g., 0) indicating that the corresponding TRP is a receiving role TRP or a second value (e.g., 1) indicating that the corresponding TRP is not a receiving role TRP.

[0284] Depending on the embodiment, a piece of role indicator information may be used to indicate whether the corresponding TRP is a single-base TRP, a transmitting role TRP, or a receiving role TRP.

Meanwhile, according to an embodiment, the frequency domain allocation information may be provided by Figure 8B It is replaced by a combination of the start RE index information and the end RE index information.

[0293] As an embodiment, when sensing resources are individually allocated to each transmit TRP (e.g., transmit role TRP / single base TRP) to remove interference, time slot repetition period information, time slot offset information, time domain allocation information, and frequency domain allocation information may be set for each transmit TRP. Alternatively, the time slot repetition period information, time domain allocation information, and frequency domain allocation information may be set identically for each transmit TRP, and only the time slot offset information may be set differently for each transmit TRP.

[0294] The sensing waveform information may specify the type of waveform used for sensing (or sensing operation). For example, the sensing waveform information may be one-bit information set to a first value (e.g., 0) indicating that the waveform type is an FMCW-based waveform or a second value (e.g., 1) indicating that the waveform type is an OFDM-based waveform.

[0295] The number of symbols used for Doppler processing may specify the number of accumulated symbols (OFDM symbols) required for Doppler processing (e.g., 32, 64, 128, 256). For example, the symbol count information used for Doppler processing may be two-bit information set to one of a first value (e.g., 0) indicating that the number of accumulated symbols required for Doppler processing is 32, a second value (e.g., 1) indicating that the number of accumulated symbols required for Doppler processing is 64, a third value (e.g., 2) indicating that the number of accumulated symbols required for Doppler processing is 128, and a fourth value (e.g., 3) indicating that the number of accumulated symbols required for Doppler processing is 256.

[0350] Reference Figure 11 In operation 1110, the TRP 320 may transmit sensing configuration information for sensing configuration to at least one UE 310. As an embodiment, the transmitting role TRP 420, the receiving role TRP 430, and the monobase TRP 440 may transmit the same sensing configuration information to at least one UE associated with the transmitting role TRP 420.

For example, the TRP 320 may transmit an RRC message including the sensing configuration information to the UE 310. For example, the TRP 320 may transmit a MAC CE including the sensing configuration information to the UE 320. For example, the TRP 320 may broadcast an SIB including the sensing configuration information. For example, the TRP 320 may transmit a DCI including the sensing configuration information to the UE 320.

[0353] According to an embodiment, the sensing configuration information may include Figure 8A 、 Figure 8B 、 Figure 8C and / or Figure 8D All or some of the information included in.

[0357] As an embodiment, the time resource allocation information may include OFDM symbol index information specifying the index of at least one OFDM symbol allocated for sensing. For example, the time resource allocation information may include Figure 9B The sensing symbol index information or the time domain allocation information of FIG. 9C .

[0358] The transmission mode information may indicate a transmission mode of the sensing signal. As an embodiment, the transmission mode may be one of a periodic transmission mode, a semi-persistent transmission mode, and an aperiodic transmission mode. As an embodiment, the multistatic sensing structure / mode may be limited to using only the periodic transmission mode, and in this case, the transmission mode information may not be included in the sensing configuration information.

[0361] Figure 12A A sensing configuration process using system information (SI) according to an embodiment of the present disclosure is shown.

[0362] Figure 12A The sensing configuration process using SI between the base station / TRP 320 and the UE 310 may be shown. Figure 12A In an embodiment, TRP 320 can be a sending role TRP 420, a receiving role TRP 430 or a single base TRP 440.

[0363] Figure 12A The embodiment corresponds to the set ID information (eg, Figure 8BAn implementation manner in which the set ID information) uses SI as the sensing configuration information to be broadcast.

[0364] Reference Figure 12A In operation 1210a, the TRP 320 may broadcast the set ID information using the SI. For example, the TRP 320 may broadcast the SIB including the set ID information. As an embodiment, the TRP 320 may periodically broadcast the set ID information.

[0365] As an embodiment, the transmitting role TRP 420 and the receiving role TRP 430 may be based on the sensing configuration information (eg, Figure 8D The set ID in the set ID information is set using the sensing configuration information of the set ID.

[0366] When the set ID information is used as the sensing configuration information, the TRP 320 and the UE 310 need to know in advance the configuration of the sensing parameter set for each set ID.

[0367] In operation 1220b, the UE 310 may receive the set ID information and obtain (or decode) the sensing parameter (sensing parameter set) based on the set ID information. For example, the UE 310 may obtain the configuration of the sensing parameter set corresponding to the set ID indicated by the received set ID information. For example, when Figure 8B The table is previously shared between the TRP 320 and the UE 310, and if the set ID indicated by the received set ID information has a value of 1, a slot repetition period having a value of 4, a slot offset having a value of 1, an OFDM symbol index for each slot having a value of 7, a start RE index having a value of 0, an end RE index having a value of 1024, a sensing waveform having an OFDM-based waveform, and a symbol count having a count of 64 for Doppler processing can be obtained as a configuration of the sensing parameter set.

[0368] Thereafter, the TRP 320 and the UE 310 may perform communication operations and / or sensing operations based on the configuration of the sensing parameter set.

[0369] In this way, when the set ID information is used as sensing configuration information, signaling overhead can be reduced.

[0370] Figure 12B A sensing configuration process using system information (SI) according to an embodiment of the present disclosure is shown.

[0371] Figure 12B The sensing configuration process using SI between the base station / TRP 320 and the UE 310 may be shown. Figure 12BIn an embodiment, TRP 320 can be a sending role TRP 420, a receiving role TRP 430 or a single base TRP 440.

[0372] Figure 12B The embodiment corresponds to a sensing parameter bitmap (eg, Figure 8C An implementation manner in which the sensing parameter bitmap is broadcast using SI as the sensing configuration information.

[0373] Reference Figure 12B In operation 1210b, the TRP 320 may broadcast the sensing parameter bitmap using the SI. For example, the TRP 320 may broadcast the SIB including the sensing parameter bitmap. As an embodiment, the TRP 320 may periodically broadcast the sensing parameter bitmap.

[0374] As an embodiment, the transmitting role TRP 420 and the receiving role TRP 430 may be based on the sensing configuration information (eg, Figure 8D The set ID in the set ID information is set using the sensing configuration information of the set ID.

[0375] When the sensing parameter bitmap is used as the sensing configuration information, the TRP 320 and the UE 310 need to know in advance the configuration of the sensing parameter set associated with the sensing parameter bitmap. For example, the TRP 320 and the UE 310 may already know the configuration of the sensing parameter bitmap.

[0376] In operation 1220c, the UE 310 may receive the sensing parameter bitmap and obtain (or decode) the sensing parameter (sensing parameter set) based on the sensing parameter bitmap.

[0377] For example, the UE 310 may obtain the configuration of the sensing parameter set corresponding to the setting value of the sensing parameter bitmap. For example, when the sensing parameter bitmap has the configuration of the sensing parameter bitmap of Figure 9C, among the total 9 bits of the sensing parameter bitmap, two LSB bits can indicate the setting value of the time slot repetition period information (for example, indicating a setting value of one of the time slot repetition periods {1, 2, 4, 8}), the next two bits can indicate the setting value of the offset information (for example, indicating a setting value of one of the time slot offset {0, 1, 2, 3}), the next bit can indicate the setting value of the time domain allocation information (for example, indicating a setting value of one of the time domain allocation {0 or 1}), the next bit can indicate the setting value of the frequency domain allocation information (for example, indicating a setting value of one of the frequency domain allocation {0 or 1}), the next bit can indicate the setting value of the waveform type information (for example, indicating a setting value of one of the waveform types {FMCW (0), OFDM (1)}), and one MSB bit can indicate the setting value of the symbol count information for Doppler processing (for example, indicating a setting value of one of the symbol count {32, 64, 128, 256}).

[0378] Thereafter, the TRP 320 and the UE 310 may perform communication operations and / or sensing operations based on the configuration of the sensing parameter set.

[0379] In this way, when the sensing parameter bitmap is used as sensing configuration information, signaling overhead can be reduced.

[0384] In the time domain, time resources for sensing may be allocated at the time slot level. In this case, the time slot repetition period information, the time slot offset information and / or the time resource allocation information may be used as sensing configuration information to configure the time resources for sensing. As an embodiment, the time resource allocation information may be Figure 8B Sensing symbol index information or Figure 8C Time domain allocation information.

In this case, as shown in the figure, the allocation of sensing symbols (or sensing resources) may be repeated in a cycle corresponding to a length of four slots, a slot offset by one slot from the start slot of the corresponding cycle (the second slot of the corresponding cycle) may be allocated as the slot to which the sensing symbol is allocated, and the second OFDM symbol in the corresponding slot may be allocated as the sensing symbol. Furthermore, unlike the example shown, multiple OFDM symbols in a slot may be allocated as sensing symbols.

[0386] Figure 13B An example of sensing resource allocation according to an embodiment of the present disclosure is shown.

[0387] In the time domain, time resources for sensing can be allocated in OFDM symbol level. In addition, in the frequency domain, time resources for sensing can be allocated in RE level.

[0388] In the case of OFDM symbol level allocation, time resources may be allocated on a per OFDM symbol basis in a time slot. In this case, the time resource allocation information may be used as sensing configuration information to configure time resources for sensing. As an embodiment, the time resource allocation information may be Figure 8B Sensing symbol index information or Figure 8C Time domain allocation information.

In this case, as shown in the figure, the frequency resources (region) from the RE corresponding to the starting RE index information of the second OFDM symbol in the corresponding time slot (starting RE) to the RE corresponding to the ending RE index information (ending RE) can be allocated as sensing symbols in consecutive REs. Furthermore, unlike the example shown, multiple OFDM symbols in a time slot can be allocated as sensing symbols. Furthermore, depending on the embodiment, consecutive frequencies can be allocated for sensing at the RB level rather than the RE level. In this case, information indicating the index of the starting RB (starting RB index information) and information indicating the index of the ending RB (ending RB index information) can serve as sensing configuration information.

In this case, as shown in the figure, the allocation of sensing symbols (or sensing resources) for sensing may be repeated in a cycle corresponding to a length of four slots, a slot offset by one slot from the start slot of the slot repetition period (the second slot of the corresponding cycle) may be allocated as the slot to which the sensing symbol is allocated, and the second OFDM symbol in the corresponding slot may be allocated as the sensing symbol. Furthermore, unlike the example shown, multiple OFDM symbols in a slot may be allocated as sensing symbols.

[0395] According to an embodiment, in the periodic transmission mode, the start time of the first cycle (time slot repetition period) may correspond to the time when the sensing configuration information for the periodic transmission mode is transmitted by the SU.

[0593] [UE Operations in the JCAS System]

[0594] Hereinafter, an operation (eg, communication operation) of a UE in a JCAS system having a multistatic sensing structure is described.

[0595] Figure 24 is a diagram illustrating a downlink (DL) communication operation of a UE in a JCAS system according to an embodiment of the present disclosure.

[0596] In the case of the JCAS system, in order to perform sensing together with communication, the base station or SU needs to allocate resources for sensing and resources for communication, and provide notification of the allocated resources to the UE 310 through the TRP. In this case, unlike in a general communication system (e.g., Figure 1 Unlike the communication system 10 of FIG. 1 , the UE 310 needs to perform an operation different from the existing communication operation in the resource region (or portion) used for the notified sensing.

[0597] In the following, reference Figure 24 The DL communication operation of the UE in the JCAS system is exemplarily described.

[0598] Reference Figure 24 In operation 1, a TRP (eg, a transmit role TRP 420 or a receive role TRP 430 or a monostatic TRP 440) may identify resources allocated for sensing. For example, the TRP may identify time and frequency resources allocated for sensing (or sensing signals).

[0599] As an embodiment, resources for sensing may be allocated by the SU 410 and may be notified to the transmitting role TRP 420 , the receiving role TRP 430 , and the monostatic TRP 440 .

[0600] In addition, a TRP (e.g., a transmit role TRP 410 or a receive role TRP 420 or a monobase TRP 440) may identify resources allocated for communication. For example, a TRP may identify time and frequency resources allocated for communication (or communication signals). Figure 24 As shown, the resources allocated for sensing and the resources allocated for communication may not overlap.

[0601] As an embodiment, resources for communication may be allocated by the SU 410 and may be notified to the transmitting role TRP 420 , the receiving role TRP 430 , and the monobasic TRP 440 .

[0602] In operation 2, a TRP (e.g., transmitting role TRP 410, receiving role TRP 420, or monostatic TRP 440) may transmit sensing configuration information including information regarding resource allocation for sensing (sensing resource allocation information) to UE 310. As an embodiment, the sensing resource allocation information may include information regarding the time and frequency resources for sensing (or sensing signals) identified in operation 1. Thus, UE 310 may be informed of the current sensing signal allocation status for the sensing signals.

[0603] Depending on the embodiment, the TRP (e.g., transmitting role TRP 410, receiving role TRP 420, or monostatic TRP 440) may transmit communication configuration information to UE 310, either together with or separately from the sensing configuration information, including information regarding resource allocation for downlink communication (DL communication resource allocation information). Depending on the embodiment, the communication resource allocation information may include information regarding the time and frequency resources for the communication (or communication signal) identified in operation 1. Thus, UE 310 may be informed of the current resource allocation status for the communication signal.

[0604] In operation 3, a TRP (eg, the transmitting role TRP 410 or the receiving role TRP 420 or the monostatic TRP 440) may perform a sensing operation using resources allocated for sensing (eg, time and frequency resources).

[0605] According to an embodiment, the transmitting role TRP 420 may transmit a sensing signal using the time and frequency resources allocated for sensing. As an embodiment, the transmitting role TRP 420 may transmit the sensing signal via at least one beam. For example, the transmitting role TRP 420 may transmit a sensing signal directed to the UE 310 via the beam 2410 directed to the UE 310.

[0606] According to an embodiment, the receiving role TRP 430 may receive the data from the target (e.g. Figure 3 The sensing device detects a reflection (reflected signal) of a sensing signal reflected by the UE 310 or the target 330 , and obtains sensing data and / or a sensing result based on the reflected signal.

[0607] According to an embodiment, the monostatic TRP 440 may use the time and frequency resources allocated for sensing to transmit sensing signals, receive signals from targets (e.g., Figure 3The monostatic TRP 440 may transmit a sensing signal directed toward the UE 310 or target 330 using a beam 2410.

[0608] Depending on the embodiment, a TRP (e.g., transmit role TRP 410, receive role TRP 420, or monobase TRP 440) may perform communication operations using resources allocated for communication (e.g., time and frequency resources). For example, the TRP may transmit communication signals (downlink communication signals) via the PDSCH using the time and frequency resources allocated for communication. Depending on the embodiment, the TRP may transmit downlink communication signals via at least one beam.

[0609] In operation 4, the UE 310 may use the received / notified information (e.g., sensing resource allocation information and sensing configuration information) to determine the operation to be performed. For example, the UE 310 may identify the time and frequency resources allocated for sensing based on the sensing resource allocation information and may perform the operation based on the identified time and frequency resources.

[0610] According to an embodiment, the UE 310 may ignore a signal received through time and frequency resources allocated for sensing ( 2420 ).

[0611] According to an embodiment, UE 310 may perform communication operations using time and frequency resources different from the time and frequency resources allocated for sensing (2430). For example, UE 310 may receive communication signals (DL communication signals) via the PDSCH using time and frequency resources allocated for DL ​​communication different from the time and frequency resources allocated for sensing. For example, UE 310 may receive the DL communication signal in an OFDM symbol having an OFDM index allocated for DL ​​communication that is different from the index of the OFDM symbol allocated for sensing.

[0612] Meanwhile, according to the embodiment, some of the above operations 1 to 4 may be omitted, and / or additional operations may be further performed. In addition, the operations may be performed in an order different from the order shown, or multiple operations may be performed simultaneously.

[0613] At the same time, Figure 24In the embodiment, for ease of description, the process between the TRP 320 and one UE 310 has been described as an example, but the embodiment is not limited thereto. For example, multiple UEs may be connected to the TRP 320, and in this case, each UE may perform the same process as that of the TRP 320 and the process between the TRP 320 and the UE 310.

[0614] Figure 25 is a diagram illustrating an uplink (UL) communication operation of a UE in a JCAS system according to an embodiment of the present disclosure.

[0615] In the case of the JCAS system, in order to perform sensing together with communication, the base station or SU needs to allocate resources for sensing and resources for communication, and provide notification of the allocated resources to the UE 310 through the TRP. In this case, unlike in a general communication system (e.g., Figure 1 Unlike the communication system 10 of FIG. 1 , the UE 310 needs to perform an operation different from the existing communication operation in the resource region (or portion) used for the notified sensing.

[0616] In the following, reference Figure 25 The UL communication operation of the UE in the JCAS system is exemplarily described.

[0617] Reference Figure 25 In operation 1, a TRP (eg, a transmit role TRP 420 or a receive role TRP 430 or a monostatic TRP 440) may identify resources allocated for sensing. For example, the TRP may identify time and frequency resources allocated for sensing (or sensing signals).

[0618] As an embodiment, resources for sensing may be allocated by the SU 410 and may be notified to the transmitting role TRP 420 , the receiving role TRP 430 , and the monostatic TRP 440 .

[0619] In addition, a TRP (e.g., a transmit role TRP 420 or a receive role TRP 430 or a monobase TRP 440) may identify resources allocated for communication. For example, a TRP may identify time and frequency resources used for communication (or communication signals). Figure 25 As shown, the resources allocated for sensing and the resources allocated for communication may not overlap.

[0620] As an embodiment, resources for communication may be allocated by the SU 410 and may be notified to the transmitting role TRP 420 , the receiving role TRP 430 , and the monobasic TRP 440 .

[0621] In operation 2, a TRP (e.g., transmitting role TRP 420, receiving role TRP 430, or monostatic TRP 440) may transmit sensing configuration information including information regarding resource allocation for sensing (sensing resource allocation information) to UE 310. As an embodiment, the sensing resource allocation information may include information regarding the time and frequency resources for sensing (or sensing signals) identified in operation 1. Thus, UE 310 may be informed of the current sensing signal allocation status for the sensing signals.

[0622] Depending on the embodiment, the TRP (e.g., transmitting role TRP 420 or receiving role TRP 430) may transmit communication configuration information to UE 310, either together with or separately from the sensing configuration information, including information regarding resource allocation for UL communication (UL communication resource allocation information). Depending on the embodiment, the UL communication resource allocation information may include information regarding the time and frequency resources for the communication (or communication signal) identified in operation 1. Thus, the UE 310 may be informed of the current resource allocation status for the communication signal.

[0623] In operation 3, a TRP (eg, the transmitting role TRP 420 or the receiving role TRP 430 or the monostatic TRP 440) may perform a sensing operation using resources allocated for sensing (eg, time and frequency resources).

[0624] According to an embodiment, the transmit role TRP 420 may transmit a sensing signal using the time and frequency resources allocated for sensing. As an embodiment, the transmit role TRP 420 may transmit the sensing signal via at least one beam. For example, the transmit role TRP 420 may transmit a sensing signal directed toward the UE 310 via a beam directed toward the UE 310.

[0625] According to an embodiment, the receiving role TRP 430 may receive the data from the target (e.g. Figure 3 The system may further comprise detecting a reflection (reflected signal) of a sensing signal reflected by the UE 310, the target 330, or the monostatic TRP 440) and obtaining sensing data and / or a sensing result based on the reflected signal.

[0626] According to an embodiment, the monostatic TRP 440 may use the time and frequency resources allocated for sensing to transmit sensing signals, receive signals from targets (e.g., Figure 3The monostatic TRP 440 may transmit a sensing signal directed toward the UE 310 or target 330 using a beam 2410.

[0627] Depending on the embodiment, a TRP (e.g., transmit role TRP 420, receive role TRP 430, or monobase TRP 440) may perform communication operations using resources allocated for communication (e.g., time and frequency resources). For example, the TRP may receive communication signals (UL communication signals) via the PUSCH using time and frequency resources allocated for UL communication. Depending on the embodiment, the TRP may receive UL communication signals using at least one beam.

[0628] In operation 4, the UE 310 may use the received / notified information (eg, sensing resource allocation information and sensing configuration information) to determine an operation to be performed. For example, the UE 310 may perform an operation based on the sensing resource allocation information.

[0629] According to an embodiment, the UE 310 may ignore the sensing signal received through the time and frequency resources allocated for sensing ( 2510 ).

[0630] According to an embodiment, the UE 310 may perform communication operations using time and frequency resources different from the time and frequency resources allocated for sensing (2520). For example, the UE 310 may transmit a communication signal (UL communication signal) using time and frequency resources allocated for UL communication different from the time and frequency resources allocated for sensing. For example, the UE 310 may transmit the UL communication signal in an OFDM symbol allocated for UL communication having an OFDM index different from the index of the OFDM symbol allocated for sensing.

[0631] Meanwhile, according to the embodiment, some of the above operations 1 to 4 may be omitted, and / or additional operations may be further performed. In addition, the operations may be performed in an order different from the order shown, or multiple operations may be performed simultaneously.

[0632] At the same time, Figure 25 In the embodiment, for ease of description, the process between the TRP 320 and one UE 310 has been described as an example, but the embodiment is not limited thereto. For example, multiple UEs may be connected to the TRP 320, and in this case, each UE may perform the same process as that of the TRP 320 and the process between the TRP 320 and the UE 310.
