Description

METHOD PERFORMED BY FIRST NODE, METHOD PERFORMED BY SECOND NODE, AND CORRESPONDING NODES IN WIRELESS COMMUNICATION SYSTEM

[0001] The present disclosure relates to the technical field of wireless communication, and in particular to a method performed by a first node, a method performed by a second node, and corresponding nodes in a wireless communication system.

[0002] Considering the development of wireless communication from generation to generation, the technologies have been developed mainly for services targeting humans, such as voice calls, multimedia services, and data services. Following the commercialization of 5th-generation (5G) communication systems, it is expected that the number of connected devices will exponentially grow. Increasingly, these will be connected to communication networks. Examples of internet-of-things may include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machines, and factory equipment. Mobile devices are expected to evolve in various form-factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In order to provide various services by connecting hundreds of billions of devices and things in the 6th-generation (6G) era, there have been ongoing efforts to develop improved 6G communication systems. For these reasons, 6G communication systems are referred to as beyond-5G systems.

[0003] 6G communication systems, which are expected to be commercialized around 2030, will have a peak data rate of tera (1,000 giga)-level bps and a radio latency less than 100μsec, and thus will be 50 times as fast as 5G communication systems and have the 1 / 10 radio latency thereof.

[0004] In order to accomplish such a high data rate and an ultra-low latency, it has been considered to implement 6G communication systems in a terahertz band (for example, 95GHz to 3THz bands). It is expected that, due to severer path loss and atmospheric absorption in the terahertz bands than those in mmWave bands introduced in 5G, technologies capable of securing the signal transmission distance (that is, coverage) will become more crucial. It is necessary to develop, as major technologies for securing the coverage, radio frequency (RF) elements, antennas, novel waveforms having a better coverage than orthogonal frequency division multiplexing (OFDM), beamforming and massive multiple input multiple output (MIMO), full dimensional MIMO (FD-MIMO), array antennas, and multiantenna transmission technologies such as large-scale antennas. In addition, there has been ongoing discussion on new technologies for improving the coverage of terahertz-band signals, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable intelligent surface (RIS).

[0005] Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink transmission and a downlink transmission to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, high-altitude platform stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile base stations and the like and enabling network operation optimization and automation and the like; a dynamic spectrum sharing technology via collision avoidance based on a prediction of spectrum usage; an use of artificial intelligence (AI) in wireless communication for improvement of overall network operation by utilizing AI from a designing phase for developing 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of user equipment (UE) computing ability through reachable super-high-performance communication and computing resources (such as mobile edge computing (MEC), clouds, and the like) over the network. In addition, through designing new protocols to be used in 6G communication systems, developing mechanisms for implementing a hardware-based security environment and safe use of data, and developing technologies for maintaining privacy, attempts to strengthen the connectivity between devices, optimize the network, promote softwarization of network entities, and increase the openness of wireless communications are continuing.

[0006] It is expected that research and development of 6G communication systems in hyper-connectivity, including person to machine (P2M) as well as machine to machine (M2M), will allow the next hyper-connected experience. Particularly, it is expected that services such as truly immersive extended reality (XR), high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems. In addition, services such as remote surgery for security and reliability enhancement, industrial automation, and emergency response will be provided through the 6G communication system such that the technologies could be applied in various fields such as industry, medical care, automobiles, and home appliances.

[0007] 5th generation (5G) or new radio (NR) mobile communications is recently gathering increased momentum with all the worldwide technical activities on the various candidate technologies from industry and academia. The candidate enablers for the 5G / NR mobile communications include massive antenna technologies, from legacy cellular frequency bands up to high frequencies, to provide beamforming gain and support increased capacity, new waveform (e.g., a new radio access technology (RAT)) to flexibly accommodate various services / applications with different requirements, new multiple access schemes to support massive connections, and so on.

[0008] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0009] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0010] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0011] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0012] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0044] FIG. 1 illustrates an example wireless network according to embodiments of the present disclosure. The embodiment of the wireless network shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 could be used without departing from the scope of the present disclosure.

[0045] As shown in FIG. 1, the wireless network includes a base station (next generation nodeB, gNB or gNodeB) 101, a gNB 102, and a gNB 103. The gNB 101 communicates with the gNB 102 and the gNB 103. The gNB 101 also communicates with at least one network 130, such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0046] The gNB 102 provides wireless broadband access to the network 130 for a plurality of first user equipments (UEs) within a coverage area 120 of the gNB 102. The plurality of first UEs includes a UE 111, which may be located in a small business; a UE 112, which may be located in an enterprise (E); a UE 113, which may be located in a WiFi hotspot (HS); a UE 114, which may be located in a first residence (R1); a UE 115, which may be located in a second residence (R2); and a UE 116, which may be a mobile device (M), such as a cell phone, a wireless laptop, a wireless personal digital assistant (PDA), or the like.

The plurality of second UEs include the UE 115 and the UE 116, as well as subscriber stations (SS, for example, UEs) 117, 118 and 119. In some embodiments, one or more of the gNBs 101-103 may communicate with each other and with the UEs 111-116 using existing wireless communication techniques, and one or more of the UEs 111-119 may communicate directly with each other (e.g., UEs 117-119) using other existing or proposed wireless communication techniques.

[0048] Dotted lines show the approximate extents of the coverage areas 120 and 125, which are shown as approximately circular for the purposes of illustration and explanation only. It should be clearly understood that the coverage areas associated with gNBs, such as the coverage areas 120 and 125, may have other shapes, including irregular shapes, depending upon the configuration of the gNBs and variations in the radio environment associated with natural and man-made obstructions.

[0050] Although FIG. 1 illustrates one example of a wireless network, various changes may be made to FIG. 1. For example, the wireless network 100 could include any number of gNBs and any number of UEs in any suitable arrangement. Also, the gNB 101 could communicate directly with any number of UEs and provide those UEs with wireless broadband access to the network 130. Similarly, each gNB 102-103 could communicate directly with the network 130 and provide UEs with direct wireless broadband access to the network 130. Further, the gNBs 101, 102, and / or 103 could provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0051] FIG. 2 illustrates an example base station according to embodiments of the present disclosure. The embodiment of the gNB 102 illustrated in FIG. 2 is for illustration only, and the gNBs 101 and 103 of FIG. 1 could have the same or similar configuration. However, gNBs come in a wide variety of configurations, and FIG. 2 does not limit the scope of the present disclosure to any particular implementation of a gNB.

[0052] As shown in FIG 2, the gNB 102 includes multiple antennas 200a-200n, multiple radio frequency (RF) transceivers 201a-201n, a transmit (TX) processing circuitry 203, and a receive (RX) processing circuitry 204. The gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface (IF) 207.

[0053] The RF transceivers 201a-201n receive, from the antennas 200a-200n, incoming RF signals, such as signals transmitted by UEs in the network 100. The RF transceivers 201a-201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are sent to the RX processing circuitry 204, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 204 transmits the processed baseband signals to the controller / processor 205 for further processing.

[0054] The TX processing circuitry 203 receives analog or digital data (such as voice data, web data, electronic mail, or interactive video game data) from the controller / processor 205. The TX processing circuitry 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. The RF transceivers 201a-201n receive the outgoing processed baseband or IF signals from the TX processing circuitry 203 and up-converts the baseband or IF signals to RF signals that are transmitted via the antennas 201a-201n.

[0055] The controller / processor 205 can include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 205 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 201a-201n, the RX processing circuitry 204, and the TX processing circuitry 203 in accordance with well-known principles. The controller / processor 205 could support additional functions as well, such as more advanced wireless communication functions.

[0056] For instance, the controller / processor 205 could support beam forming or directional routing operations in which outgoing signals from multiple antennas 200a-200n are weighted differently to effectively steer the outgoing signals in a desired direction. Any of a wide variety of other functions could be supported in the gNB 102 by the controller / processor 205.

[0057] The controller / processor 205 is also capable of executing programs and other processes resident in the memory 206, such as an operating system (OS). The controller / processor 205 can move data into or out of the memory 206 as required by an executing process.

[0058] The controller / processor 205 is also coupled to the backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems over a backhaul connection or over a network. The interface 207 could support communications over any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G, LTE, or LTE-A), the interface 207 could allow the gNB 102 to communicate with other gNBs over a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the interface 207 could allow the gNB 102 to communicate over a wired or wireless local area network or over a wired or wireless connection to a larger network (such as the Internet). The interface 207 includes any suitable structure supporting communications over a wired or wireless connection, such as an Ethernet or RF transceiver.

[0059] The memory 206 is coupled to the controller / processor 205. Part of the memory 206 could include a random access memory (RAM), and another part of the memory 206 could include a Flash memory or other read only memory (ROM).

[0060] Although FIG. 2 illustrates one example of gNB 102, various changes may be made to FIG. 2. For example, the gNB 102 could include any number of each component shown in FIG. 2. As a particular example, an access point could include a plurality of interfaces 207, and the controller / processor 205 could support routing functions to route data between different network addresses. As another particular example, while shown as including a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, the gNB 102 could include multiple instances of each (such as one per RF transceiver). Also, various components in FIG. 2 could be combined, further subdivided, or omitted and additional components could be added according to particular needs.

[0061] FIG. 3 illustrates an example user equipment according to embodiments of the present disclosure. The embodiment of the UE 116 illustrated in FIG. 3 is for illustration only, and the UEs 111-115 and 117-119 of FIG. 1 could have the same or similar configuration. However, UEs come in a wide variety of configurations, and FIG. 3 does not limit the scope of the present disclosure to any particular implementation of a UE.

[0062] As shown in FIG. 3, the UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, TX processing circuitry 303, a microphone 304, and receive (RX) processing circuitry 305.

The memory 311 includes an OS 312 and one or more applications 313.

[0063] The RF transceiver 302 receives, from the antenna 301, an incoming RF signal transmitted by an gNB of the network 100. The RF transceiver 302 down-converts the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is sent to the RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. The RX processing circuitry 305 transmits the processed baseband signal to the speaker 306 (such as for voice data) or to the processor 307 for further processing (such as for web browsing data).

[0064] The TX processing circuitry 303 receives analog or digital voice data from the microphone 304 or other outgoing baseband data (such as web data, e-mail, or interactive video game data) from the processor 307. The TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuitry 303 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 301.

[0065] The processor 307 can include one or more processors or other processing devices and execute the OS 312 stored in the memory 311 in order to control the overall operation of the UE 116. For example, the processor 307 could control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceiver 302, the RX processing circuitry 305, and the TX processing circuitry 303 in accordance with well-known principles. In some embodiments, the processor 307 includes at least one microprocessor or microcontroller.

[0066] The processor 307 is also capable of executing other processes and programs resident in the memory 311, such as processes for CSI (Channel State Information) reporting on uplink channel. The processor 307 can move data into or out of the memory 311 as required by an executing process. In some embodiments, the processor 307 is configured to execute the applications 313 based on the OS 312 or in response to signals received from gNBs or an operator. The processor 307 is also coupled to the I / O interface 308, which provides the UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the processor 307.

[0067] The processor 307 is also coupled to the touchscreen display 310. The user of the UE 116 can use the touchscreen display 310 to enter data into the UE 116. The touchscreen display 310 may be a liquid crystal display, light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from web sites.

[0068] The memory 311 is coupled to the processor 307. Part of the memory 311 could include RAM, and another part of the memory 311 could include a Flash memory or other ROM.

[0069] Although FIG. 3 illustrates one example of UE 116, various changes may be made to FIG. 3. For example, various components in FIG. 3 could be combined, further subdivided, or omitted and additional components could be added according to particular needs. As a particular example, the processor 307 could be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Also, while FIG. 3 illustrates the UE 116 configured as a mobile telephone or smartphone, UEs could be configured to operate as other types of mobile or stationary devices.

[0070] The demand for the use of wireless data in the production activities of human society is gradually increasing, and the spectrum is gradually becoming a scarce resource. How to optimize the communication system and improve the spectrum utilization of the communication system has always been a hot issue for practitioners. At present, low-frequency resources for wireless communication are crowded, and the operating frequency band of the communication system is gradually developing towards higher frequency, so it is inevitable to conflict with the radar system that originally operates in the high frequency band. The cellular communication system and the radar system have very high similarity in terms of background theoretical knowledge and hardware structure, so the convergence of the cellular communication system and the radar system can be used as a potential means to improve the spectral efficiency. Meanwhile, the communication system and the radar system may also complement each other in performance to achieve mutual benefits and win-win results. Therefore, the integrated sensing and communications (ISAC for short), as a hot research direction in the communication field, becomes one of the candidate technologies of 6G. The core of the ISAC system is to use the same set of hardware devices to realize the function of sensing the surrounding environment at the expense of as little resource overhead as possible on the basis of ensuring the basic communication function. The sensed contents include, but not limited to, the distance, orientation, speed and even type of an object in the surrounding environment. Unlike the technology of positioning the access terminal in the conventional communication system, the ISAC technology can also sense various information of non-access objects, thus greatly improving the capability of the communication system to dynamically adjust the operating state (scheduling, beam management, early warning of access terminals, etc.) according to the surrounding environment.

[0071] At present, the most widely used communication systems are systems based on the 3rd generation partnership project (3GPP) protocol, for example, 4G communication systems such as LTE and LTE-A, and 5G communication systems such as NR. The signal waveforms used in these communication systems are all waveforms based on OFDM modulation. Considering forward compatibility, for example, OFDM communication signals can be used as sensing signals. Specifically, the sensing signal may be a physical signal and / or physical channel that can be used for sensing purposes. For example, when the sensing node is a base station, the sensing signal may be a downlink reference signal, a downlink physical channel or the like; and, when the sensing node is a terminal / user equipment, the sensing signal may be an uplink reference signal, an uplink physical channel or the like. The sensing signal sent by the sensing node is reflected by the target reflector and then re-received by the sensing node in the form of echo. The distance, speed, orientation or other sensing information of the target object can be sensed by processing the echo signal. The ISAC is expected to realize a sensing function, for example, a target detection function, including but not limited to determining the presence or absence of the target. Optionally, the sensing function may also include at least one of distance estimation of the target, speed estimation of the target and orientation estimation of the target.

[0072] In order to better satisfy the requirements of ISAC, the embodiments of the present disclosure provide a scheme for sensing measurement reporting. Based on the scheme provided by the present disclosure, a sensing node (e.g., a first node) may provide the sensing measurement result to another node (e.g., a second node), and the other node may perform related processing based on the received sensing measurement report.

[0073] In the embodiments of the present disclosure, the sensing mode may be classified into a single-node sensing mode and a multi-node sensing mode. In one optional implementation of the single-node sensing mode, the sensing node sends a sensing signal and receives an echo, and performs sensing measurement based on the echo. The multi-node sensing mode includes information interaction between at least two nodes. In one optional implementation, a third node sends a sensing signal, the sensing signal is reflected by a target object and then received by a first node, and the first node may perform sensing measurement (e.g., target detection) based on the received signal and reports a sensing measurement result to a second node, wherein the second node and the third node may be the same or different.

[0074] In the embodiments of the present disclosure, the transmitting node (transmitter) and the receiving node (receiver) of the sensing signal may be the same node or different nodes. In one implementation, the first node sends a sensing signal and receives an echo, and reports a sensing measurement result to the second node. In another implementation, the second node sends a sensing signal, and the first node receives an echo signal, performs sensing measurement and reports a sensing measurement result to the second node.

[0075] The specific way of calculating, by the sensing node, the sensing measurement result based on the received signal (the signal for sensing measurement) will not be limited in the embodiments of the present disclosure. Optionally, the sensing node may receive a first signal related to the sensing function. The first signal is the received signal corresponding to a second signal, the second signal includes at least one sensing signal, and one sensing signal may include at least one sub physical signal. The sensing node may perform sensing based on the first signal and report a sensing measurement report. Optionally, the sensing node may perform sensing based on the signal of at least one time window in the first signal. One time window may be correlated to at least one sub physical signal and / or correlated to a signal spaced apart from the sub physical signal by a first interval. The correlation here may include, but not limited to, the alignment of the position of the time window with the time-domain position of the sub physical signal. In the embodiments of the present disclosure, the mode of sensing measurement based on the signal in a single time window is called single-window measurement or single-window detection, and the mode of sensing measurement based on signals in at least two time windows is called multi-window measurement or multi-window detection.

[0076] In the embodiments of the present disclosure, the "time window" may be a window with a specific length (e.g., at least one of the time duration, the number of sampling points and the number of symbols); and a plurality of time windows may have the same length, or at least some of a plurality of time windows may have different lengths. The way of determining the related information (e.g., duration, starting time, ending time, etc.) of the "time window" will not be uniquely limited in the embodiments of the present disclosure, and may be predetermined, or configured, or determined according to an indication or other related parameters.

[0077] The name of the term "time window" will not be limited, and may also be called "window", "data window", "observation window", "time window", "detection window", "monitoring window", "sensing window", "auxiliary window", "time unit" or the like.

[0078] In the scheme provided in the embodiments of the present disclosure, the sensing signal (the signal for sensing) may be communication signals in the communication system, such as the above OFDM communication signal, or may be sensing signals used in the radar system, such as linear frequency modulation signals, or may be radio signals with a sensing function generated in other ways. Optionally, the sensing signal may be communication signals such as reference signals or pilot signals, to better realize forward compatibility. The meaning of the sensing signal includes, but not limited to, a special physical signal used for the integrated sensing and communications, wherein the physical signal that can be used for the integrated sensing and communications may be a reference signal. For example, the reference signal may be a demodulation reference signal, including demodulation reference signals of uplink / downlink shared channels, demodulation reference signals of uplink / downlink control channels, demodulation reference signals of broadcast channels or the like; and, the reference signals may also be sounding reference signals (SRSs), channel state information reference signals (CSI-RSs) or the like. The physical signal that can be used for the integrated sensing and communications may also be data signals or channels, for example, uplink / downlink / sidelink signals or channels carrying data, such as PUSCHs / PDSCHs; for another example, uplink / downlink / sidelink signals or channels carrying control information, such as PUCCHs / PDCCHs.

[0079] In the optional embodiments provided by the present disclosure, the type / format / style of the sensing signal, the occupied resource and other related information will not be uniquely limited. For example, the sensing signal may be a signal including a single sub physical signal, or may be a signal including a plurality of sub physical signals. Optionally, some information in the related information of the sensing signal may be predetermined, or may be configured, for example, configured for the UE by the base station.

[0080] The method provided in the embodiments of the present disclosure may be performed by any electronic device / node. For example, this node may be a user equipment in a wireless communication system or may be a network node, wherein the network node may be a base station or other network nodes, for example, a transmission / reception point (TRP), a relay node, a road side station or the like, e.g., a road side unit (RSU). The base station may be a base station with separated central and distributed units, or may be an integrated base station. For a separated base station, the node may be the central unit of the base station, or may be the distributed unit of the base station. The electronic device / node may also include one of the following: a core network, a positioning server (e.g., an LTE positioning protocol (LPP) server, etc.), a location management function (LMF) entity (e.g., the LMF may be located in the core network, or may be a local location management function entity located in the radio access network), a sensing function (SF) entity (e.g., the SF may be located in the core network, or may be a local sensing function entity located in the radio access network), and a sensing network element.

[0081] In addition, it is to be noted that some term names involved in the embodiments of the present disclosure may adopt the term names that already exist in the communication standards, while some term names may be newly added or defined term names. These newly added or defined term names may also adopt other names in future communication standards, or may be described in other ways (e.g., a paragraph of text description). The names or appellations of various signals / information / messages / parameters / configurations involved in the embodiments of the present disclosure are not unique; and theoretically, the names or appellations of these signals / information / messages / parameters / configurations can be altered as long as the functions or contents of these signals / information / messages / parameters / configurations or the explanations or descriptions of these signals / information / messages / parameters / configurations can be corresponding or associated.

[0082] For example, the sensing signal in the embodiments of the present disclosure may also be called a signal related to the sensing function, a sensing integration signal, an integration signal, a physical signal or other names. In the embodiments of the present disclosure, the transmitted / sent signal refers to the sensing signal sent by the transmitter, and the received signal refers to the signal corresponding to the sensing signal received by the receiver. For example, if the transmitter transmits a sensing signalaand the receiver receives a signalbcorresponding to the sensing signala(e.g., the echo of the sensing signala), the signalais the transmitted signal, and the signalbis the received signal.

[0083] In the embodiments of the present disclosure, the receiver (e.g., the first node) receiving the signal related to the sensing function may be described as that the receiver receives the signal / echo signal corresponding to the sensing signal, or may even be described as that the receiver receives the sensing signal, because the receiver receives the corresponding signal for the purpose of sensing although the sensing signal may not be transmitted by the receiver. For example, in the above example, the transmitter transmitting the sensing signalaand the receiver receiving the signalbmay also be described as that the receiver receives the signal a. It is clear to those skilled in the art that, due to the influence of attenuation, interference and other factors in the signal transmission process, the signal related to the signalareceived by the receiver and the transmitted signalaare corresponding signals but are not exactly the same. In addition, in addition to the sensing related signal, there may also be other signals in the signal received by the receiver. The other signals may include interference signals, or may include signals used for other functions, for example, data signals or signals for transmitting control information.

[0084] The technical solutions provided by the present disclosure and the technical effects achieved by the technical solutions will be described below by various optional implementations. The following implementations can be referred to, learned from or combined with each other if not conflicted or contradicted, and the same terms, similar characteristics, similar implementation steps or the like in different implementations will not be repeated.

[0085] For the interaction steps between different nodes (e.g., a node acting as the transmitter and a node acting as the receiver), the solution corresponding to the node on the one side can be obtained based on the description of the solution of the node on other side. For example, if a node receives a signal, it can be correspondingly concluded that a node (transmitter) sends a signal, and the corresponding node (receiver) receives the signal. The transmitter and the receiver may be the same node or different nodes. One transmitter may correspond to one or more receivers, and one receiver may receive signals transmitted by one or more different transmitters. In an embodiment including a plurality of steps, if the plurality of steps has no clear precedence order, the execution order of the plurality of steps is not uniquely defined in the embodiments of the present disclosure.

[0086] The optional implementations of the method provided by the present disclosure will be further described below with reference to the principle of the solutions provided by the present disclosure and several optional embodiments, and the steps in different embodiments can be combined or replaced with each other if not conflicted.

[0087] FIG. 4 shows a method performed by a first node in a wireless communication system according to an embodiment of the present disclosure. This method provides a new solution for reporting a sensing measurement report, wherein the first node is a receiving node / receiver. Optionally, the first node may be a user equipment, or the first node may be an intermediate node in the communication system, for example, a relay node in a relay network; or, the first node may also be a base station or a road side station. As shown in FIG. 4, the method may include the following steps.

[0088] In step S410, the first resource for reporting a sensing measurement report is determined.

[0089] In step S420, a sensing measurement report is sent to a second node on the first resource.

[0090] Optionally, the determining a first resource may include: determining the first resource based on at least one of first information, second information, a format of a sensing signal and capability information of the first node.

[0091] The first resource for reporting is a resource for transmitting a sensing measurement report. The first resource may include at least one of a time domain resource, a frequency domain resource and a beam domain resource. In the embodiment of the present disclosure, the granularity of the resource will not be limited. For example, the granularity of the time domain resource may be one OFDM symbol. Optionally, the first resource may be a reporting occasion. For example, the first node is configured with at least one reporting occasion, and the first node may select, from the configured reporting occasions, one or more occasions for reporting a sensing measurement report according to at least one of the above information.

[0092] In the embodiment of the present disclosure, the sending a sensing measurement report may also be described as reporting a sensing measurement report, sending a sensing result, sending a sensing measurement result or sending a sensing measurement quantity. The sensing measurement report includes at least one sensing measurement quantity, i.e., at least one of sensing information obtained based on the sensing related signal, for example, the distance, direction, angle, speed or the like of a target object. The sensing measurement quantity may include a sensing measurement quantity related to one or more sensing signals, for example, a sensing measurement result calculated based on the received signal corresponding to one or more sensing signals.

[0093] The second node may be a base station or a user equipment. For example, the first node may be a first base station, and the second node may be a second base station; or, the first node may be a UE, and the second node may be a base station; or, the second node may be a first UE, and the first node may be a first UE. For example, in a V2X application scenario, the first node and the second node may be vehicles, and the first vehicle may receive first information from a base station and send a measurement result to the second vehicle based on the first information.

[0094] In the embodiment of the present disclosure, the first information may be determined by the first node (e.g., the base station) itself, or the method may further include:

[0095] receiving the first information. That is, the first information may also be received by the first node from another node, and the other node may be or may not be the second node. The first node may send at least one sensing measurement report to the second node based on the first information. For example, the first node may be a user terminal, for example, a UE or other terminal devices, and the base station may configure the first information for the first node. For the convenience of description, in some embodiments hereinafter, the first information is also called sensing measurement reporting configuration, sensing reporting configuration or the like.

[0096] In the embodiment of the present disclosure, the first information may be information related to sensing measurement reporting, and may include, but not limited to, information related to sensing measurement requirements. The first information may include, but not limited to, information related to sensing measurement requirements, and may also include one or more of related information of a sensing signal associated with sensing measurement, related information of a sensing signal associated with reporting, and information related to a reporting resource. Based on the first information, the first node may know one or more of the sensing measurement report that should be reported, the resource on which the sensing measurement report can be reported, and other information.

[0097] The sensing measurement requirements may be interpreted as information related to the content expected to be reported, for example, the condition or constraint information that should be satisfied by the content expected to be reported. Based on the information related to sensing measurement requirements, the first node may report a measurement result satisfying the requirements to the second node, that is, the sensing measurement result reported by the first node may be a sensing result satisfying the requirements.

[0098] In the embodiment of the present disclosure, the format of the sensing signal is the style or type of the sensing signal, which may be one of a plurality of specified styles or types. The sensing signal may be a single-symbol signal or a multi-symbol signal, for example, a double-symbol signal, wherein the single-symbol signal occupies one OFDM symbol, while the double-symbol signal occupies two OFDM symbols. Optionally, the single-symbol signal or multi-symbol signal may include one or more sub physical signals. For a sensing signal containing a plurality of sub physical signals, the plurality of sub physical signals in the sensing signal may be the same or different signals. For example, they may be the same signals (e.g., reference signals). Optionally, sensing signals with different formats may have different sensing capabilities, for example, different maximum sensing distances. The way of defining the format of the sensing signal will not be limited in the embodiment of the present disclosure, and may include, but not limited to, the above way of classifying the format according to the number of resources occupied by the signal.

[0099] In an optional embodiment of the present disclosure, the sensing signal includes a cyclic prefix (CP) and at least one sub physical signal. Optionally, the format of the sensing signal may be related to at least one of the numbers of sub physical signals included in the sensing signal, the length of sub physical signals and the length of the CP in the sensing signal.

[0100] For sensing signals with different formats, the information such as the mode based on which the first node performs the sensing measurement and the required sensing measurement time may be different. Therefore, as an alternative, the first node may determine the first resource for reporting the sensing measurement report based on the format of the sensing signal. Optionally, the first node may determine the first resource for reporting the sensing measurement report based on at least one of the first information, the number of sub physical signals, the length of the CP and the length of sub physical signals.

[0101] In the embodiment of the present disclosure, the second information may also be called sensing signal configuration, sensing resource configuration, sensing measurement resource configuration or the like, and the second information includes information related to one or more sensing signals, such as information related to the format of the sensing signal and information related to the resource occupied by the sensing signal. The first node may perform sensing measurement based on the received signal corresponding to one or more sensing signals associated with the second information, and report a sensing measurement result corresponding to at least one sensing signal.

[0102] In the embodiment of the present disclosure, the capability information of the first node includes the sensing related capability of the first node, which may be the capability of the first node to process the sensing signal. The representation of the sensing capability information will not be limited. Optionally, the capability information is represented by reusing one or more existing parameters related to node capability in the communication system. For example, the first node may be a UE, and the sensing capability information of the UE may be related to the type of the UE. For another example, the first node may be a customer premise equipment (CPE), and the sensing capability information of the CPE may be relate to the type of the CPE.

[0103] Optionally, the capability information of the first node may include at least one of the following:

[0104] the number of sensing measurement processing units (SPUs) supported by the first node; and

[0105] the number of unoccupied sensing measurement processing units for the first node.

[0106] The embodiment of the present disclosure provides a new parameter for representing the sensing capability of the node, i.e., the sensing measurement processing unit. The name of the sensing measurement processing unit will not be limited in the embodiment of the present disclosure, and may be any other names. For example, the sensing measurement processing unit may also be represented by a sensing processing unit, a detection processing unit or the like.

[0107] In this optional scheme, such capability of a node may be represented by the number of SPUs. The larger the number is, the higher the capability is. The number may be the number of SPUs supported by the node or the number of unoccupied SPUs of the node. The SPU may be interpreted as the capability of the node to process the sensing signal or the capability of the node to perform sensing measurement. The reporting of the sensing measurement report by the first node needs to occupy the resource for the first node. The sensing measurement processing unit is used to represent the resource for the first node related to sensing measurement. For example, the number of SPUs supported by the first node represents the resource amount of related resources possessed by the first node, and the number of unoccupied SPUs for the first node represents the resource amount of related resources currently available for the first node.

[0108] In practical applications, different nodes may have different capabilities, so the nodes with different capabilities may take different time to obtain sensing measurement results when performing sensing measurement. In addition, sensing signals with different formats and difference in resources on which communication is based may also affect the time required by the first node to perform sensing measurement. If a node has higher capability, the node is more efficient in processing the sensing signal and can obtain the sensing measurement result corresponding to the sensing signal faster, so that the sensing measurement report can be reported faster. Therefore, the first resource for reporting the sensing measurement report may be related to the capability information of the first node.

[0109] Optionally, the method further includes: sending the capability information of the first node to a third node, for example, sending, to the third node, related information of at least one of the number of SPUs supported by the first node and / or the number of unoccupied SPUs, and / or information related to the type of the UE to the third node.

[0110] The third node may be the second node or other nodes. Optionally, the first node may receive configuration information sent by the third node, and the configuration information includes at least one of the first information and / or the second information.

[0111] Optionally, the first node sending the capability information to the third node may include: receiving, by the first node, information related to capability reporting (i.e., a capability information reporting instruction), and sending, by the first node, the capability information to the third node in response to the information.

[0112] Based on the above solution provided by the present disclosure, the first node may acquire configuration information more suitable for the capability information of the first node. Optionally, the first node may receive the received signal corresponding to the sensing signal based on the second information in the configuration information, perform measurement based on the one or more received signals and send the sensing measurement report to the second node based on the second information.

[0113] The embodiment of the present disclosure provides a new solution for reporting the sensing measurement result, which is different from that in the prior art. By using this method, any node in the communication system can determine a first resource for reporting based on the combination of one or more of the first information, the second information, the format of the sensing signal and the capability information of the first node, and send a sensing measurement report to the second node on the corresponding resource. The solution provided by the present disclosure provides a support for subsequent processing based on the sensing measurement result.

[0114] The first information, the second information, the format of the sensing signal and the capability information of the first node as well as an optional scheme for reporting the sensing measurement result based on one or more of the first information, the second information, the format of the sensing signal and the capability information of the first node in the embodiment of the present disclosure will be described below.

[0115] Optionally, the first information includes information related to sensing measurement requirements, and the information related to sensing measurement requirements may include information related to at least one of the following:

[0116] sensing range, and sensing accuracy.

[0117] The sensing range may include a range related to at least one sensing parameter; the sensing parameter may include, but not limited to, one or more of sensing distance, sensing speed, sensing angle and sensing orientation; and, the sensing accuracy may include, but not limited to, one or more of sensing distance accuracy, sensing angle accuracy, sensing speed accuracy and sensing orientation accuracy. For a sensing parameter, the sensing accuracy corresponding to this parameter refers to the accuracy satisfied by the sensing result corresponding to this parameter. For example, by taking sensing distance as an example, the sensing distance accuracy refers to the accuracy of the sensing result of the distance, for example, meter-level accuracy, decimeter-level accuracy or the like.

[0118] In the embodiment of the present disclosure, the sensing range may be the maximum sensing value, the minimum sensing value, a range interval or the like. Based on the information related to sensing measurement requirements, the first node may only report a sensing measurement result that satisfies the sensing range requirement. Optionally, the information related to the sensing distance / sensing speed / sensing angle / sensing range may be information related to a maximum sensing distance (or distance interval) / sensing speed (or speed interval) / sensing angle (or angle interval) / sensing orientation (or orientation interval).

[0119] Based on the information related to the sensing range, the first node may know one or more of the maximum sensing distance / distance interval corresponding to reporting, the maximum sensing speed / speed interval, the maximum sensing angle / angle interval and the maximum sensing orientation / orientation interval corresponding to reporting. The first node may report, among the sensing measurement results, a sensing measurement result satisfying at least one of the following, and may not report measurement results beyond the sensing range requirement:

[0120] a measurement result that belongs to the maximum sensing distance / distance interval;

[0121] a measurement result that belongs to the maximum sensing speed / speed interval;

[0122] a measurement result that belongs to the maximum sensing angle / angle interval; and

[0123] a measurement result that belongs to the maximum sensing orientation / orientation interval.

[0124] The sensing measurement result reported by the first node may be the measurement results corresponding to all sensing signals / sensing signal sets / sensing signal groups, or may be the measurement result of the sensing signal / sensing signal group / sensing signal set corresponding to the index of at least one sensing signal / sensing signal group / sensing signal set associated with sensing measurement, or may be the measurement result of the sensing signal / sensing signal group / sensing signal set corresponding to the index of the sensing signal / sensing signal group / sensing signal set associated with reporting. One sensing signal group may include one or more sensing signals, and one sensing signal set may include one or more sensing signal groups.

[0125] Optionally, in the sensing measurement process, the number of sensing signals / signal groups / signal sets on which sensing measurement (or reporting) is based may determine the maximum sensing range corresponding to measurement (or reporting), for example, one or more of the maximum sensing speed, the maximum sensing distance, the maximum sensing angle or the maximum sensing orientation. The first node determines the sensing range based on the above number of sensing signals / signal groups / signal sets. Optionally, in the sensing measurement process, the beam direction corresponding to the sensing signals / signal groups / signal sets on which the sensing measurement (or reporting) is based may determine the sensing angle / orientation corresponding to the sensing measurement (or reporting); and, the first node may determine the sensing angle / orientation based on the beam direction, may report the measurement report belongs to the sensing angle / orientation range among the sensing measurement results and may not report measurement results beyond this range.

[0126] In the embodiment of the present disclosure, the indices of the sensing signals / sensing signal groups / sensing signal sets are the identifiers of the sensing signals / signal groups / signal sets. The sensing signals / signal groups / signal sets associated with reporting may also be called the sensing signals / signal groups / signal sets on which reporting is based, i.e., the sensing signals / signal groups / signal sets related to the sensing measurement report. The index of at least one sensing signal / signal group / signal set being associated with sensing measurement means that it is expected that the first node can report the sensing measurement result (e.g., at least one sensing measurement quantity) of the sensing signals / sensing signal groups / sensing signal sets corresponding to the indices.

[0127] The sensing signals / signal groups / signal sets associated with sensing measurement may also be called the sensing signals / signal groups / signal sets for sensing measurement. According to the index of at least one sensing signal / signal group / signal set associated with sensing measurement, the first node may know that sensing measurement should be performed based on the sensing signals / sensing signal groups / sensing signal sets corresponding to the indices, that is, the sensing measurement result may be calculated based on the received signal corresponding to the sensing signal of the indices.

[0128] The index of at least one sensing signal / sensing signal group / sensing signal set on which reporting is based may be some or all of the indices of sensing signals / signal groups / signal sets on which the sensing measurement is based. The first node may report, according to one or more indices on which reporting is based, the sensing measurement results corresponding to some or all of the sensing signals in these indices.

[0129] Optionally, the first information may include the information related to sensing measurement requirements and / or at least one of the following:

[0130] the index of at least one sensing signal associated with sensing measurement; the index of at least one sensing signal group associated with sensing measurement, wherein one sensing signal group includes at least one sensing signal; the index of at least one sensing signal set associated with sensing measurement, wherein one sensing signal group includes at least one sensing signal group; information related to sensing measurement processing units required for sensing measurement; the index of at least one sensing signal associated with reporting; the index of at least one sensing signal group associated with reporting; the index of at least one sensing signal set associated with reporting; information related to a reporting resource (e.g., information related to at least one reporting occasion); and, information related to the format of the sensing signal.

[0131] In the embodiment of the present disclosure, the information related to sensing measurement processing units required for sensing measurement is the information related to the capability of the first node required for sensing measurement, and may be described as the occupied resource (e.g., computing resource) for the first node required for sensing measurement. Optionally, the information related to SPUs required by the sensing measurement requirements may be the information related to the number of SPUs required for sensing measurement. The number of SPUs required for sensing measurement refers to the resource for the first node occupied by the first node to perform sensing measurement, and may refer to the number of SPUs for the first node required for one sensing measurement, for example, the number of SPUs required by performing sensing measurement based on one sensing signal / sensing signal group / sensing signal set.

[0132] Optionally, based on the information related to SPUs required for the sensing measurement requirement, the first node may determine whether all sensing measurement results that are expected to be reported can be reported, or only some of the sensing measurement results can be reported. For example, if the first node is configured to report N sensing measurement reports (e.g., reporting the sensing measurement results corresponding to N sensing signals), but the total number of SPUs for the first node required by the N sensing measurement reports exceeds the number of unoccupied SPUs for the first node, the first node may give up reporting, or report as many sensing measurement reports as possible according to the number of unoccupied SPUs. Optionally, the first node may report some sensing measurement reports with higher priorities.

[0133] In the embodiment of the present disclosure, the reporting resource is the resource used for reporting the sensing measurement report, and the information related to a reporting resource refers to the information related to the resource for transmitting the measurement report. Based on this information, the first node may determine the configured resource for transmitting the measurement report.

[0134] Optionally, the information related to a reporting resource may include the information related to at least one reporting occasion, that is, the reporting resource may include at least one reporting occasion. Based on the information related to a reporting resource, the first node may determine various reporting occasions, and the first node may select one or more occasions (e.g., first resources) for transmitting the report from the reporting occasions; or, when one or more reporting occasions configured for the first node are not appropriate, the first node may give up sending the measurement report, or the first node may send a resource request to the second node or the third node and the second node or third node reconfigures one or more reporting occasions for the first node based on the request from the first node. Optionally, this request may include information related to a first time and / or information related to a second time, wherein the first time may be the earliest time when the first node can transmit the measurement report, and the second time may be the reporting time expected by the first node. On this basis, an optional scheme of the present disclosure may further include: sending, by the first node, third information to the second node, the third information being related to the resource (e.g., time) for transmitting the sensing measurement report.

[0135] If there is an appropriate (available) reporting occasion in the one or more configured sensing measurement reporting occasions, the first node may notify the selected reporting occasion to the second node, that is, the third information may include information related to the actual transmission occasion of the measurement report; and, the second node may receive the measurement report sent by the first node in the corresponding reporting occasion. Or, if there is no appropriate reporting occasion in the configured reporting occasions, the first node may re-request the second node a resource for transmitting the sensing measurement report by sending the related third information (e.g., the above resource request).

[0136] In the embodiment of the present disclosure, the first resource for reporting may also be related to the sub-carrier spacing. Since the size of the sub-carrier spacing will affect the communication rate, the communication quality and the time duration between two adjacent sampling points, different sub-carrier spacings will affect the time required by the first node to receive information and thus affect the time when the first node can perform reporting. Optionally, the possible earliest reporting time for the first node may be determined according to the sub-carrier spacing, and at least one first resource may be determined based on the possible earliest reporting time.

[0137] Optionally, the information related to at least one reporting occasion may include one or more of information related to the starting time of at least one reporting occasion (e.g., the first reporting occasion), information related to the time difference between adjacent reporting times, duration information of at least one reporting occasion and other information. For example, a plurality of reporting occasions are continuous in time, and the duration of each reporting occasion is the same, so the first node may determine other reporting occasions according to the starting time and duration of the first reporting occasion.

[0138] As an optional scheme, the information related to at least one reporting occasion includes at least one of the following:

[0139] information related to the first reporting occasion, the number of reporting occasions, and the offset (e.g., time domain offset and / or frequency domain offset) between adjacent reporting occasions.

[0140] Based on the information related to the first reporting occasion, the first node may determine the position of the first reporting time and may then determine the positions of other reporting times based on the offset between adjacent reporting occasions.

[0141] In the embodiment of the present disclosure, the information related to a reporting resource may include information related to the offset K2, wherein the offset is the time and / or frequency offset between the resource occupied by the configuration information and the reporting resource (i.e., the resource for transmitting the measurement report). Optionally, the offset may be the offset between the slot where the configuration information is located and the slot where the resource for reporting (e.g., at least one reporting occasion) is located. Optionally, the offset may be the offset between the frequency domain position where the configuration information is located and the frequency domain position where the resource for reporting (e.g., at least one reporting occasion) is located. The configuration information may include at least one of the first information and / or the second information.

[0142] Optionally, the offset K2 may be related to at least one of the following:

[0143] the sub-carrier spacing; the capability information of the first node, the capability information including the number of SPUs supported by the first node and / or the number of unoccupied SPUs for the first node; the capability of SPUs required for sensing measurement; the number of signals associated with sensing measurement, the number of signals including at least one of the number of sensing signals, the number of sensing signal groups and the number of sensing signal sets; the format of the sensing signal; and, the sensing measurement requirements.

[0144] The sensing measurement requirements may represent the level of a measurement requirement. The higher the measurement requirement, the larger the offset may be, because the first node needs to take more time to obtain a measurement result satisfying the requirement when the measurement requirement is higher. Optionally, the sensing measurement requirements may include the expected sensing range. The larger the sensing range is, the larger the offset is.

[0145] Optionally, the offset K2 may be the time difference between the time domain resource (e.g., the slot, the symbol, the sampling point, or the basic time unit defined by the NR system) where the configuration information is located and the time domain resource (i.e., the reporting resource, e.g., the slot, the symbol, the sampling point, or the basic time unit defined by the NR system) occupied by the measurement report. Based on the offset and the time of the configuration information obtained by the first node, the first node may calculate the position of the time domain resource (e.g., the slot, the symbol, the sampling point, or the basic time unit defined by the NR system) occupied by the sensing measurement reporting, e.g., the time domain position of each configured reporting occasion.

[0146] Optionally, the offset K2 may be the difference between the frequency domain position (e.g., sub-carrier, RE index, RB index, RBG index, PRB index, CRB index, VRB index, or BWP index) where the configuration information is located and the frequency domain position (e.g., sub-carrier, RE index, RB index, RBG index, PRB index, CRB index, VRB index, or BWP index) occupied by reporting. Based on the offset and the frequency domain position in the configuration information obtained by the first node, the position of the frequency domain resource (e.g., sub-carrier, RE index, RB index, RBG index, PRB index, CRB index, VRB index, or BWP index) occupied by the sensing measurement reporting may be calculated.

[0147] Based on the resource where the configuration information is located and the offset K2, the first node may determine the configured reporting resource. For example, the offset K2 is the slot difference between the slot where the configuration information is located and the configured first reporting slot. Based on the offset, the first node may determine the slot where the first reporting occasion is located.

[0148] In the embodiment of the present disclosure, the second information may be determined by the first node itself, or may be configured. Optionally, the method provided in the embodiment of the present disclosure may further include:

[0149] receiving the second information including information related to at least one sensing signal.

[0150] Optionally, the second information may include at least one of the following:

[0151] the information related to the format of the sensing signal; the index of at least one sensing signal; the index of at least one sensing signal group; the index of at least one sensing signal set; the information related to at least one resource, wherein the at least one resource includes at least one of the resource occupied by at least one sensing signal, the resource occupied by at least one sensing signal group and the resource occupied by at least one sensing signal set; the information related to the transmission period of at least one sensing signal; the information related to the transmission period of at least one sensing signal group; the information related to the transmission period of at least one sensing signal set; the information related to the number of sensing signals; the information related to the number of sensing signal groups; and, the information related to the number of sensing signal sets.

[0152] In the embodiment of the present disclosure, when the transmitting node sends a sensing signal, the mode of transmitting a sensing signal for one time can be adopted, or the mode of transmitting a sensing signal group or a sensing signal set can also be adopted. The "indices" mentioned in the description of the second information are the indices of the sensing signals / signal groups / signal sets to be transmitted by the transmitting node. The identification mode of the indices will not be limited in the embodiment of the present disclosure. For example, if M sensing signals are transmitted, the indices of the M sensing signals may be 0, 1, ..., M-1 successively. The "at least one resource" is the resource occupied by the sent sensing signal / signal group / signal set.

[0153] The "at least one sensing signal", "at least one sensing signal group" or "at least one sensing signal set" involved in the description of the second information can correspond to one or more sensing signals. The "more" here can mean that there are a plurality of signals, or the number of transmissions of the signal / signal group / signal set is greater than 1. For example, at least one sensing signal may be a plurality of signals transmitted for one time, or may be a plurality of signals transmitted for multiple times. One sensing signal group / sensing signal set may include a plurality of sensing signals, or at least one sensing signal group / sensing signal set includes a plurality of sensing signal groups / sensing signal sets. Each sensing group / signal set among the plurality of sensing signal groups / sensing signal sets may include one or more sensing signals, or the sensing signal set / sensing signal group is transmitted for multiple times. In other words, the second information acquired by the first node may be the information corresponding to at least two sensing signals (e.g., at least two reference signals).

[0154] Optionally, the at least two sensing signals corresponding to the second information have different sensing capabilities (e.g., maximum sensing distances).

[0155] The sensing signal / sensing signal group / sensing signal set may be transmitted periodically or aperiodically. In the periodical transmission mode, the second information may also include the information about the period. For a sensing signal group, the period may include the period between sensing signal groups, and / or the period between sensing signals in the sensing signal group. For a sensing signal set, the period may include at least one of the period between sensing signal sets / the period between sensing signal groups in the sensing signal set, and the period between sensing signals in the sensing signal group.

[0156] Based on the above second information, the first node may know one or more of the format of the sensing signal, the number of sensing signals / sensing signal groups / sensing signal sets, the occupied resource, the transmission period and other information, receive the received signals corresponding to at least one sensing signal / signal group / signal set, perform sensing based on some or all of the received signals, and obtain measurement results corresponding to one or more sensing signals / signal groups / signal sets.

[0157] Optionally, the determining the first resource for reporting the sensing measurement report may include:

[0158] determining the first resource based on at least one of the following:

[0159] the first information, the format of the sensing signal, the number of sensing signals, the number of sensing signal groups, the number of sensing signal sets, the number of sampling points corresponding to one sensing signal, the processing time for one sensing signal, the number of sensing measurement processing units supported by the first node, and the number of unoccupied sensing measurement processing units for the first node.

[0160] At least one of the format of the sensing signal, the number of sensing signals, the number of sensing signal groups, the number of sensing signal sets, the number of sampling points corresponding to one sensing signal and the processing time for one sensing signal may be known by the first node based on the second information, or may be predetermined.

[0161] The information related to at least one resource included in the second information may include the information related to the resource occupied by each sensing signal / signal group / signal set. Optionally, the information related to at least one resource includes: information related to the first resource, and information related to a relative relationship;

[0162] wherein the first resource is at least one of a resource occupied by a first sensing signal, a resource occupied by a first sensing signal group and a resource occupied by a first sensing signal set; and

[0163] the relative relationship includes at least one of the following:

[0164] information on an interval between resources occupied by adjacent sensing signals; information on an interval between resources occupied by adjacent sensing signal groups; and, information on an interval between resources occupied by adjacent sensing signal sets.

[0165] Based on this optional scheme, in a case where the second information corresponds to at least two sensing signals, for example, when the number of sensing signals / sensing signal groups / sensing signal sets (e.g., the number of transmissions) is greater than 1, the first node may determine the first resource (e.g., the resource occupied by the first sensing signal) according to the information related to the first resource in the second information, and the first node may determine the resources occupied by other sensing signals / sensing signal groups / sensing signal sets based on the first resource and the above relative relationship. For example, according to the second information, the first node may know the resource occupied by the sensing signal with an index of 1 (e.g., the index of the sensing signal transmitted for the first time), the number of transmissions of the sensing signal being 3 and the relative position relationship between resources occupied by adjacent sensing signals being of difference ofaslots. Thus, the first node may determine the transmitting resource of each sensing signal according to the second information, and may receive the received signals corresponding to the sensing signals on the corresponding resource, perform sensing based on some or all of the received signals and report sensing measurement reports corresponding to some or all of the received signals on the first resource.

[0166] As an optional scheme, the first node may determine the first resource for reporting the sensing measurement report in the following ways:

[0167] determining a first time interval based on at least one of the first information, the second information, the format of the sensing signal and the capability information of the first node, the first time interval being the minimum interval between a time unit where the sensing signal associated with sensing measurement is located and a time unit where the corresponding sensing measurement report is located; and

[0168] determining the first resource for reporting the sensing measurement report based on the first time interval.

[0169] For example, the first node may determine the first time interval based on at least one of the first information and the format of the sensing signal. For any sensing signal for which the sensing measurement report needs to be reported, the time unit difference between the time unit where the sensing signal is located and the time unit where the corresponding sensing measurement report is located cannot be less than the first time interval. The first node may select, from available reporting resources, a reporting resource satisfying a condition according to the first time interval.

[0170] In the embodiment of the present disclosure, the sensing signal may include a CP and at least one sub physical signal, and the determining a first time interval may include:

[0171] if the number of sub physical signals is 1, determining the first time interval based on the length of the CP; and

[0172] if the number of sub physical signal is at least 2, determining the first time interval based on the length of the CP and the length of the at least one sub physical signal.

[0173] Considering that the required time may be different when sensing measurement is performed based on the received signals corresponding to sensing signals with different formats, the first time interval may be related to the format of the sensing signal. Sensing signals with different formats may have different sensing capabilities / sensing ranges, and the sensing capability / sensing range of the sensing signal is related to the equivalent CP of the sensing signal, so the first time interval may be related to the equivalent CP length of the sensing signal. If a sensing signal includes only one sub physical signal, the equivalent CP length of this sensing signal is the length of the real CP of this signal; if a sensing signal includes a plurality of sub physical signals, the equivalent CP length of this sensing signal may be the length of the real CP of this sensing signal or the sum of the length of the real CP and the length of at least one sub physical signal. For example, if a sensing signal includes a CP and two sub physical signals, the equivalent CP length of this sensing signal may be sum of the length of the CP and the length of the first sub physical signal.

[0174] As an optional scheme, the first time interval includes a first number of time units, and the determining the first resource for reporting the sensing measurement report may include:

[0175] determining a second resource, a cyclic prefix of the second source starting from a next uplink time unit after the first number of time units after the end of the last time unit where the nthsensing signal is located, the resource used for reporting a sensing measurement report of the nthsensing signal being not earlier than the second resource, where n≥1; and

[0176] determining the first resource based on the second resource.

[0177] The second resource can be interpreted as considering the time required by the first node to receive the received signal corresponding to the sensing signal and calculate the sensing measurement result based on the received signal, and the transmission time of the sensing measurement report corresponding to one sensing signal is unlikely to be earlier than the time of measurement based on the sensing signal and / or obtaining the sensing measurement result by calculation. Optionally, the second resource may be a next possible resource that can be used for reporting when the time required for measurement and / or calculation is considered. For example, if it is necessary to report the sensing measurement report corresponding to the first sensing signal, the second resource may be a next uplink time unit after the first number of time units after the last time unit occupied by the first sensing signal.

[0178] The granularity of the uplink time unit will not be uniquely limited in the embodiment of the present disclosure. Optionally, one time unit may be one OFDM symbol.

[0179] Optionally, the determining the first resource may further include: determining a third resource based on at least one of the first information, the second information, the capability information of the first node and the format of the sensing signal, wherein the third resource is the first uplink time unit after a second number of time units after the time unit where the configuration information (information including the first information and / or the second information) is located, and the resource used for reporting is not earlier than the third resource.

[0180] Optionally, the cyclic prefix of the third resource starts from a next resource after a second number of resources after the end of the last resource where the configuration information is located, and the resource used for reporting is not earlier than the third resource. The third resource can be interpreted as the required resource when the time required by the first node to decode the configuration information is considered, and the reporting time of the first node is unlikely to be earlier than the decoding completion time. Optionally, the third resource may be a next uplink symbol after a first number of symbols after the last symbol where the configuration information is located. The first node may determine the first resource based on at least one of the second resource, the third resource and at least one configured reporting resource.

[0181] Optionally, the first number and / or the second number may be related to at least one of the following:

[0182] the sub-carrier spacing; the number of SPUs supported by the first node; the number of unoccupied SPUs for the first node; the number of SPUs required for sensing measurement; the number of signals on which sensing measurement is based, the number of signals including at least one of the number of sensing signals, the number of sensing signal groups and the number of sensing signal sets; the format of the sensing signal; and, the sensing measurement requirement.

[0183] Optionally, the first node may determine the first number and / or the second number by looking up a table based on at least one of the above items. For example, the first node may determine the first number and / or the second number by looking up a table according to the sub-carrier spacing, and may then determine the second resource and / or the third resource. The description of at least one of the above information can refer to the related description in other embodiments and will not be repeated here.

[0184] After determining one or more first resources (e.g., one or more reporting occasions), the first node may report the sensing measurement report on the first resource. Optionally, the first node sending a sensing measurement report to the second node may include:

[0185] sending at least one sensing measurement report to the second node based on at least one of the following:

[0186] the capability information of the first node, the capability information including at least one of the number of SPUs supported by the first node and the number of unoccupied SPUs for the first node; the priority information related to sensing measurement; the capability information of the first node required for sensing measurement, e.g., the number of SPUs required for sensing measurement; and, the sensing measurement requirements.

[0187] Optionally, the priority information is related to a sensing delay requirement.

[0188] Optionally, the capability information of the first node required for sensing measurement is related to at least one of the following:

[0189] the format of the sensing signal associated with sensing measurement; the sensing measurement requirements; the number of sub physical signals included in the sensing signal; the length of the CP of the sensing signal; the length of sub physical signals included in the sensing signal; the number of sensing signals; the number of sensing signal groups; the number of sensing signal sets; the number of sampling points corresponding to one sensing signal; the number of sampling points corresponding to one sub physical signal; and, the processing time for one sensing signal.

[0190] Optionally, if the first node can report the measurement results of all the received sensing signals (acquiring all sensing signals on which the measurement reporting configured in the sensing configuration is based), the first node reports all the measurement results to the second node, or reports, based on the first information, the sensing measurement results corresponding to all sensing signals expected to be reported. If the first node cannot report all measurement results, the first node may report some measurement results based on one or more pieces of the above information.

[0191] For example, the first node is configured to report the sensing measurement reports of three sensing signals (denoted as signal 1, signal 2 and signal 3), where the priority of the signal 1 is higher than that of the signal 2, and the priority of the signal 2 is higher than that of the signal 3; the number of occupied SPUs for the first node is 6; the sensing measurement of the signal 1 requires 3 SPUs, the sensing measurement of the signal 2 requires 2 SPUs, and the sensing measurement of the signal 3 also requires 2 SPUs. Thus, the first node may only report the sensing measurement results corresponding to the signal 1 and signal 2. Optionally, the sensing measurement requirements (e.g., the sensing ranges) can also be taken into account. If the sensing measurement results corresponding to high priorities do not satisfy the requirements, high priorities that do not satisfy the requirements can be excluded, and the measurement results satisfying the requirements corresponding to lower priorities can be reported. For example, in the above example, if it is assumed that the sensing measurement result corresponding to the sensing signal 2 does not satisfy the sensing measurement requirements and the sensing measurement results corresponding to the signal 1 and signal 3 satisfy the requirements, the sensing measurement results corresponding to the signal 1 and signal 3 can be reported.

[0192] Optionally, the first information may include one or more pieces of information related to the priority information of sensing measurement, and the first node may know the priority corresponding to each sensing measurement according to the information.

[0193] Optionally, different sensing scenarios may correspond to different priorities. For example, the configuration information may include scenario related information, and the first node may determine, based on the information, the priority corresponding to the sensing signal / sensing signal group / sensing signal set by looking up a table or by other predetermined ways. Or, the sensing scenario where the first node is located is unchanged, and the first node may know the priority based on this sensing scenario by looking up a table or by a predetermined way. The classification of the type of the application scenario will not be limited in the embodiment of the present disclosure. For example, the sensing measurement corresponding to a scenario with higher delay requirements may have a higher priority.

[0194] The number of SPUs required for each sensing signal may be configured by the first node, or may be calculated by the first node according to one or more pieces of information related to this number. For example, the first information includes the information related to the number of SPUs required for the sensing measurement of at least one sensing signal, or the first node may calculate this number according to the predetermined calculation mode.

[0195] Optionally, according to the number of SPUs required for the sensing signal, the number of unoccupied SPUs for the first node and the priority of the sensing signal, the first node may report the sensing measurement reports corresponding to one or more high-priority sensing signals that can be reported by the first node at most.

[0196] The embodiment of the present disclosure provides a new communication scheme related to the sensing application. Based on this scheme, the first node may realize the sensing function based on the received signal corresponding to the received sensing signal (which is actually the echo signal of the sensing signal sent by the transmitting node) and may report a sensing measurement result to the second node. Thus, the problem of the absence of the standardized process of the measurement reporting related to sensing in the ISAC system is solved.

[0197] Optionally, the sensing signal in the embodiment of the present disclosure may be a communication signal in the communication system, for example, a reference signal, so that the compatibility of the communication system and the radar system in the ISAC system can be realized. That is, by using the communication signal, the sensing function can be realized while the communication function is realized.

[0198] The operation implementations of the solution provided by the present disclosure will be described below by some optional embodiments. In practical applications, the steps in different embodiments can be combined or replaced with each other if not conflicted.

[0199] FIGS. 5A and 5B show optional implementations of the solution provided by the present disclosure. As shown in FIG. 5A, a nodeamay receive configuration information from a nodeband report a sensing measurement result (i.e., sending a sensing measurement report) to the nodebbased on the configuration information, wherein the configuration information may include first information and / or second information. In FIG. 5B, a nodeamay receive configuration information from a nodeband send a measurement report to a nodecbased on the configuration information.

[0200] The name of the "configuration information" will not be limited in the embodiment of the present disclosure, and may be called sensing configuration, sensing related configuration, sensing measurement configuration, sensing reporting configuration or other names.

[0201] Optionally, when the first node is a UE, the UE may receive the configuration information from a base station. The way of transmitting the configuration information will not be limited in the present disclosure. Optionally, the first node may obtain the configuration information by receiving a physical layer signaling or a high-layer signaling. As an alternative, the configuration information may be carried in an RRC message, wherein the RRC message may include, but not limited to, an RRC configuration message, an RRC reconfiguration message, an RRC establishment message or the like.

[0202] Optionally, when the first node is a base station, acquiring configuration information related to sensing can be interpreted as that the base station determines information related to sensing measurement or the base station receives the configuration information from other network elements (e.g., base stations or core network elements, etc.).

[0203] For the convenience of description, the following description will be given in some embodiments by taking the first node being a UE, the second node being a base station and the second node and the third node being the same as an example.

[0204] The first information may be interpreted as the information related to the sensing measurement requirements and sensing measurement quantity reporting, and the first information may be called sensing measurement reporting configuration or reporting configuration. The first information may include at least one parameter used for determining the information needed to be reported. For example, at least one of the content of the sensing measurement report sent by the first node and the report sending occasion is determined based on the first information. For example, the first information may include the index of at least one specified signal, and may also include one or more reporting occasions, wherein the specified signal refers to a sensing signal for which the measurement result needs to be sent. Based on the first information, the first node may send a measurement report to the second node on at least one configured reporting occasion. This report at least includes the sensing measurement result corresponding to the at least one specified signal. Optionally, the first information may also include information related to measurement parameters. For example, based on the configuration information, the type of the measurement quantity to be calculated can be known, for example, a measurement quantity related to distance detection, a measurement quantity related to orientation / angle, a measurement quantity related to speed, and one or more measurement quantities among the measurement quantities related to other physical quantities / parameters.

[0205] In the embodiment of the present disclosure, the measurement reporting may be a periodic report or an aperiodic reporting. For the periodic reporting, the first node may perform sensing measurement periodically and send a sensing measurement report to the second node periodically. Optionally, the configuration information may include period related information. For the aperiodic reporting, the first node may perform reporting for one time or multiple times based on one configuration information. During one-time reporting, the sensing measurement result corresponding to at least one sensing signal may be sent, and the measurement result corresponding to one sensing signal may include at least one sensing measurement quantity.

[0206] The second information may also be called sensing resource configuration. Based on the second information, the first node may determine the resource occupied by the sensing signal, i.e., the time frequency resource for transmitting the sensing signal. The first node may receive the received signal corresponding to the sensing signal on the corresponding resource and perform sensing measurement (e.g., performing a target detection algorithm) based on the received signal to obtain a sensing measurement result. Optionally, before the first node sends the sensing measurement report to the second node, the method may further include:

[0207] receiving, based on the second information, at least one first signal related to sensing, the first signal being the received signal corresponding to a second signal, the second signal including at least one of at least one sensing signal, at least one sensing signal group and at least one sensing signal set.

[0208] The sensing measurement report sent to the second node by the first node is related to the at least one sensing signal / signal group / signal set in the received signal.

[0209] The first signal may be an echo signal received by the first node for the sensing signal sent by another node (e.g., the second node) (a multi-node sensing mode), or may be an echo signal received by the first node for the sensing signal sent by the first node (a single-node sensing mode). Another node may send one or more sensing signals, and the first node may receive signals on the resource corresponding to the sensing signals based on the second information and calculate and report sensing measurement results based on some or all of the received signals.

[0210] Optionally, the sensing measurement report may include the measurement result corresponding to each transmitted sensing signal / signal group / signal set, or may be the measurement results corresponding to some sensing signals / signal groups / signal sets. The sensing information reported to the second node by the first node may be predetermined by the system (for example, only the measurement result corresponding to a specific sensing result is reported, and the specific sensing signal may be at least one sensing signal sent by the node that sends the sensing signal), or may be determined by the first node based on the first information. For example, the first information includes the indices of one or more sensing signals on which reporting is based, and the first node may only report the sensing measurement results of some or all of the sensing signals corresponding to these indices. For example, the first node may report, according to its own capability, the sensing measurement results that can be reported by the first node among the sensing measurement results corresponding to these indices. Optionally, the first node determines, according to the configuration information and / or its own capability, that the measurement results of the sensing signals corresponding to which indices can be reported on the configured reporting occasions, and the first node may neither calculate nor report the measurement results of sensing signals other than the sensing signals that can be reported.

[0211] In the embodiment of the present disclosure, the first information and the second information may be or may not be obtained simultaneously. The first information and the second information may be contained in the same configuration information, or may be contained in different pieces of configuration information, respectively. As an alternative, the first node acquiring the configuration information may include: acquiring first configuration information including the second information, and acquiring second configuration information including the first information. The first configuration information and the second configuration information may be the same configuration information, or may be different pieces of configuration information.

[0212] The configuration information acquired by the first node may include the information related to the format of the sensing signal, and the first node may know the format of the sensing signal based on this information. Optionally, the format of the sensing format may also correspond to the sensing measurement method, and the first node may determine, according to the information related to the format of the sensing signal, which sensing measurement method (e.g., which target detection algorithm) should be adopted.

[0213] As an optional scheme, FIGS. 6A and 6B show schematic diagrams of sensing signals of two formats according to the present disclosure. The sensing signal shown in FIG. 6A may include a CP and 1 sub physical signal, i.e., a sub physical signal 1, where the CP is the cyclic prefix of the sensing signal. The length of the rectangular box where the CP is located can schematically indicate the length of the CP, and the length of the rectangular box where the sub physical signal 1 is located can schematically indicate the length of this signal. When performing sensing measurement based on this sensing signal, the first node may calculate and obtain a sensing measurement result and report the sensing measurement result, e.g., a target detection result, based on the signal of a data widow A in the received signal, wherein the position of the data window A may be related to at least one sub physical signal in the sensing signal. For example, the position of the data window A in FIG. 6A is aligned with the position of the sub physical signal 1.

[0214] The sensing signal shown in FIG. 6B may include a CP and 2 sub physical signals, i.e., a sub physical signal 1 and a sub physical signal 2, wherein the sub physical signal 1 and the sub physical signal 2 may have the same signal length or different signal lengths. Optionally, in this example, the first node may perform sensing measurement based on the received signal corresponding to the sub physical signal 2. For example, the first node may perform target detection based on the received signal of the data window A related to (e.g., position aligned to) the position of the sub physical signal 2 to obtain a target detection result. The signal length is the information representing the length of the signal in the time domain, and can be interpreted as the time information occupied by the signal in the time domain, for example, one OFDM symbol, or can be interpreted as the number of sampling points corresponding to the signal.

[0215] Other signals in FIGS. 6A and 6B will not be limited in the embodiment of the present disclosure and can be any signals in the communication system, for example, signals of data channels, or signals of control channels, or reference signals.

[0216] In the embodiment of the present disclosure, the sensing capability (e.g., maximum sensing distance) of one sensing signal may correspond to the length of the cyclic prefix of this sensing signal. The length of the cyclic prefix corresponding to one signalamay be the length of the equivalent cyclic prefix of this signala. The equivalent cyclic prefix may also be called an extended cyclic prefix, a sensing cyclic prefix or other names. The length of the equivalent cyclic prefix may be the length of the actual cyclic prefix of this signala, or the length of at least one signalbbefore this signala, or the sum of the signal length of at least one signalbbefore this signalaand the length of the CP before the at least one signal. Both the signalaand the at least one signalbare sensing related signals, and the signalaand the at least one signalbmay be continuous in the time domain. The signalaand the signalbmay be sensing signals or sub physical signals. In the example shown in FIG. 6A, the equivalent cyclic prefix of the sub physical signal 1 is the length of the CP. In the example shown in FIG. 6B, the equivalent cyclic prefix of the sub physical signal 2 may be the length of the CP, or the length of the sub physical signal 1, or the length of the sub physical signal 1 and the CP.

[0217] When performing sensing measurement, the transmitting node may send one or more sensing signals. The second information may include the information related to the resource occupied by at least one sensing signal, and the resource may include a time domain resource and / or a frequency domain resource and / or a beam domain resource. Based on this information, the first node can know the resource for each sensing signal transmission, e.g., at least one of the transmission time, the occupied frequency band and the beam where the transmission occurs, and thus can receive the sensing signal on the corresponding resource. Optionally, sensing related measurement can be performed based on the resource.

[0218] Optionally, the second information may also include the index of at least one sensing signal to be sent by the transmitting node, i.e., the identifier of the sensing signal. Optionally, the second information may also include the indices of at least two sensing signals to be sent by the transmitting node, i.e., the identifiers of the sensing signals. Optionally, the second information may also include the number of sensing signals to be sent by the transmitting node. For example, if there are three sensing signal to be sent and the indices are 0, 1 and 2 successively, the second information may include indication information of the resource corresponding to the index 0, the resource corresponding to the index 1 and the resource corresponding to the index 2, or the second information includes indication information of the resource corresponding to the index 0. The resources occupied by the sensing signals corresponding to different indices are correlated, so the first node may determine the resources corresponding to the index 1 and index 2 according to the resource corresponding to the index 0. For example, the resources occupied by adjacent sensing signals or adjacent sensing signal groups or adjacent sensing signal sets are correlated, for example, they are adjacent and occupy the same resource amount, so the first node may determine the resources corresponding to other indices according to the resource occupied by the sensing signal / sensing signal group / sensing signal set corresponding to any index indicated in the configuration information.

[0219] FIG. 7 shows a flowchart of a method for reporting a sensing measurement result according to an optional embodiment of the present disclosure. As shown in FIG. 7, this method may include the following steps.

[0220] In step 1, a first node (e.g., a UE) reports information related to its own capability to a second node (e.g., a base station). The capability includes the capability of the first node related to sensing measurement, for example, the number of available SPUs of the first node (e.g., Nspu in FIG. 7), the type of the first node and other capability information. The step 1 is an optional step. Optionally, before sending the capability information to the second node, the first node may also receive a capability information reporting indication (e.g., a UE capability query signaling) sent by the second node. The first node reports the related capability according to the reporting indication.

[0221] In step 2, the first node receives a sensing related configuration from the second node. Optionally, the sensing related configuration may include configuration information (second information) related to the sensing signal and configuration information (first information) related to the sensing measurement reporting. As shown in FIG. 7, the second information may include a sensing resource configuration, and the first information may include a sensing measurement configuration and a configuration related to the sensing measurement reporting time. Optionally, the sensing measurement reporting time may include information on one or more sensing reporting times, e.g., a plurality of reporting occasions.

[0222] In step 3, the first node sends a sensing measurement report (i.e., the sensing measurement result reporting shown in FIG. 7) to the second node based on the sensing related configuration. Optionally, this step may include one or more steps in the following steps S31 to S35.

[0223] In step S31, the first node receives a sensing signal sent by the second node. Optionally, the first node may receive the received signals corresponding to at least one sensing signal based on the sensing resource configuration, or receive the received signal corresponding to at least one sensing signal group or at least one sensing signal set. It should be understood that the first node receiving the sensing signal sent by the second node may also be described as that the first node receive the echo signal of the sensing signal sent by the second node. Due to the interference, the reflection of the target object or other reasons, the signal sent by the second node is not exactly the same the signal received by the first node, but it can still be described as that the second node sends a sensing signal and the first node receives the sensing signal sent by the second node. This is clear for those skilled in the art.

[0224] In step 32, based on the capability information of the first node and some or all information in the sensing related configuration, the first node determines a first resource for reporting the sensing measurement report, including calculating the sensing measurement reporting time. In this step, before reporting the sensing measurement result, the first node may also perform computing resource conflict judgment and time conflict judgment based on its own capability information (e.g., the number of available SPUs) and the sensing related configuration information received from the second node, and then perform conflict processing. The first node may also calculate the sensing measurement reporting time based on the judgment result, and select the sensing measurement reporting time.

[0225] Optionally, the computing resource conflict judgment includes: determining a content to be reported based on the capability of the first node and the sensing related configuration. For example, if the current capability of the first node can report all contents expected to be reported by the first node in the sensing related configuration, there is no conflict in computing resources, and the first node can perform reporting according to the configuration. If the current capability of the first node cannot report all contents according to the configuration, for example, if it is configured in the sensing related configuration that the first node is configured to report N sensing measurement reports but the number of available SPUs of the first node cannot satisfy the number of SPUs required for N sensing measurement reports, the first node may report less than N sensing measurement reports through the computing resource conflict judgment. Optionally, the first node may report M sensing measurement reports with higher priorities, or determine M sensing measurement results to be reported according to the predetermined order or judgment rule, wherein the number of SPUs of the first node required for reporting M sensing measurement reports is not greater than the number of available SPUs of the first node.

[0226] Optionally, the time conflict judgment includes: determining, by the first node, the information of the earliest time when the first node can send the sensing measurement report according to the sensing related configuration, and calculating the sensing measurement reporting time based on the information of the earliest time and the sensing measurement reporting time configured for the first node, for example, selecting the actual reporting occasion from a plurality of configured reporting occasions.

[0227] In step 33, the first node sends the information related to the reporting time to the second node. By using this information, the first node may notify the selected sensing measurement reporting time to the second node.

[0228] In step S34, the first node performs measurement based on the sensing signal. The implementation order of the steps 32, 33 and 34 will not be limited.

[0229] In step S35, the first node reports a sensing measurement result to the second node, i.e., sending a sensing measurement report to the second node.

[0230] In the embodiment of the present disclosure, the content included in the sensing related configuration will not be uniquely limited. Several optional schemes of the sensing related configuration (also referred to as sensing configuration) provided in the present disclosure will be described below.

[0231] Optionally, the sensing related configuration may be obtained based on at least one of an RRC signaling, a medium access control (MAC) control element (CE) or physical layer control information. Optionally, the physical layer control information may include, but not limited to, downlink control information (DCI).

[0232] Optionally, the sensing related configuration may include a first parameter (second information) related to the sensing signal (e.g., reference signal / pilot signal), and a second parameter (first information) related to the sensing measurement requirements and sensing measurement quantity reporting. Optionally, the first parameter may include at least one of the following:

[0233] information related to the format (also referred to as style or type) of the sensing signal; the indices or identifiers (IDs) of at least one sensing signal; information related to the resource (e.g., time domain resource) occupied by the sensing signal; information related to the number of transmissions of the sensing signal; and, information related to the transmission period of the sensing signal.

[0234] Optionally, the sensing signal may be a time domain signal that occupies a certain period of time / symbol / sampling point. For example, in one configuration, the sensing signal occupies at least one symbol in one slot. For example, the sensing signal may be a single-symbol signal that occupies one symbol, or a double-symbol signal that occupies two symbols.

[0235] Optionally, the sensing signal may be a signal transmitted periodically, or a signal transmitted aperiodically. Optionally, the sensing signal, sensing signal group or sensing signal set may be transmitted for one time or multiple times.

[0236] The optional schemes of the sensing related configuration will be described below with reference to the examples shown in FIGS. 8A to 8D.

[0237] FIG. 8A shows an optional scheme of the sensing related configuration. In this optional scheme, the sensing related configuration (the sensing configuration in this figure) may include the information related to the transmission time of the sensing signal and the time information related to the sensing measurement reporting. In one configuration, the number of transmissions of the sensing signal may be 1. For example, the sensing signal configuration (the first parameter) may include the information indicating the transmission slot of the sensing signal, and may also include the starting symbol index and occupied length (e.g., the number of symbols) of the sensing signal. Based on the first parameter, the first node may know the transmission time of the sensing signal and then receive the sensing signal at the corresponding time. Optionally, as shown in FIG. 8A, the information related to the transmission time of the sensing signal may include an offset K1, where K1 represents the interval between the sensing configuration and the first sensing signal in one or more its scheduled sensing signals. The representation of the interval will not be limited in the present disclosure. For example, the value of K1 may directly represent the number of slots. For example, K1=1, it means that the difference between the slot of sending the sensing configuration and the slot of sending the first sensing signal is 1; or, the value of K1 has a correspondence relationship with the number of slots.

[0238] Optionally, the sensing configuration (the second parameter) may also include the information related to the time of the sensing measurement reporting, e.g., an offset K2 in FIG. 8A, where K2 represents the interval between the slot where the sensing configuration is located and the slot where the scheduled sensing measurement quantity reporting is located. When there are a plurality of configured sensing measurement reports, the interval may be the interval between the slot where the sensing configuration is located and the first sensing measurement reporting (the first node may determine, based on the interval, the times of other sensing measurement reports, for example, the time difference between adjacent reporting times is predetermined,), or may include the interval between the sensing configuration and each sensing measurement report.

[0239] FIG. 8B shows another optional scheme of the sensing related configuration. In this configuration, the number of transmissions of the sensing signal may be N, where N≥1. Optionally, N sensing signals form one sensing signal group. Optionally, the sensing signal configuration may indicate the starting slot of sending the sensing signal, the starting symbol index and occupied length (e.g., the number of symbols) of the sensing signal, and the period (e.g., the number of slots) of a single sensing signal in the sensing signal group. Based on the sensing signal configuration, the first node may know the transmission time of each sensing signal. For example, the first node may determine the starting time of sending the first sensing signal according to the offset K1, may receive the first sensing signal according to the starting time and the number of resources occupied by the sensing signal, and may receive other sensing signals according to the number of sensing signals in the sensing signal group and the time difference (e.g., the above period) between adjacent sensing signals. Similarly, the sensing configuration (the second parameter) may also include the information related to the time of the sensing measurement reporting, e.g., the offset K2 in FIG. 8B.

[0240] FIG. 8C shows another optional scheme of the sensing related configuration. In this configuration, as shown in FIG. 8C, the number of transmissions of the sensing signal group may be M, M sensing signal groups may form one sensing signal set, and one sensing signal group includes sensing signals transmitted for N times, where N≥1. Optionally, the sensing signal configuration may indicate the period (e.g., the number of frames / sub-frames) of a single sensing signal group in the sensing signal set. Different sensing signal groups in the sensing signal set may have the same or different periods. In this optional scheme, the offset K1 represents the interval between the transmission slot of the sensing configuration and the starting transmission slot of the first sensing signal group.

[0241] As an optional scheme, the first parameter related to the sensing reference signal in the sensing configuration may include information related to one or more of the following:

[0242] the index or ID of the sensing signal / sensing signal group / sensing signal set; the time frequency resource occupied by the sensing signal (e.g., the time offset K1 between the sensing configuration and the slot where the sensing signal is located, or the symbol or sampling point offset); the starting symbol index and occupied length (e.g., the number of symbols) of the sensing signal; the format of the sensing signal (e.g., the number of repeated sub physical signals in the sensing signals); and, the number of transmissions of the sensing signal.

[0243] In practical implementations, one or more of the above information may be included in the configuration, and some information may also be predetermined. For example, the length of the resource occupied by one sensing signal is fixed. For example, two symbols are occupied by sending a sensing signal for one time.

[0244] Optionally, the offset K1 represents the interval between the sensing configuration information and the first sensing signal in one or more its scheduled sensing signals. For example, with reference to the examples shown in Figs. 8A to 8C, K1 may represent the interval between the slot where the sensing configuration information is located and the slot where the first sensing signal in one or more its scheduled sensing signals is located. When the value of K1 is 0, it indicates that the interval is 0 slot, that is, the sensing configuration information and the first sensing signal in the one or more its scheduled sensing signals are transmitted in the same slot; and, when the value of K1 is 1, it indicated that the interval is 1 slot, that is, the slot where the sensing configuration information is located is the slot X, and the first sensing signal in the one or more its scheduled sensing signals is transmitted in the slot X+1. When this parameter is defaulted, the value of K1 may be a value predetermined by default. For example, when this parameter is defaulted, the value of K1 is defaulted to be 0 by the first node.

[0245] Optionally, the second parameter related to the sensing measurement requirements and sensing measurement quantity reporting in the sensing related configuration may include information related to at least one of the following:

[0246] the index or ID of the sensing reference signal on which sensing measurement is based; the parameter related to the sensing range (e.g., the sensing range may be related to the format of the sensing signal; for example, one sensing signal may include at least one sub physical signal, and the sensing range may be related to the length of the sub physical signal or related to the equivalent CP length of the sensing signal); the number of SPUs required for sensing measurement; the index or ID of at least one sensing signal corresponding to the measurement quantity reporting; and, the resource occupied by the measurement reporting, e.g., the time frequency resource occupied by the measurement quantity reporting corresponding to the index or ID of at least one sensing signal.

[0247] The index or ID of the sensing reference signal on which sensing measurement is based (i.e., the sensing signal associated with sensing measurement) may be interpreted as the index or ID for which the first node is configured to perform sensing measurement, and the sensing measurement result is obtained by performing sensing measurement on the sensing signal corresponding to this index or ID. For example, the sensing measurement result is obtained by performing target detection on the sensing signal corresponding to this index or ID. This index or ID may be the identifier of the sensing signal that the first node is expected to report the corresponding sensing measurement result, and may be the identifiers of some or all of the sensing signals sent by the second node.

[0248] The "sensing range" in the parameter related to the sensing range may be interpreted as the sensing measurement results in this sensing range that the first node is expected to report. The first node may report, to the second node, the measurement results satisfying this sensing range among the sensing measurement results obtained based on the each received sensing signal (which may be each sensing signal received based on the first parameter or may be the index or ID of the sensing signal on which sensing measurement is based).

[0249] The number of SPUs required for sensing measurement represents the capability of the first node to be occupied by sensing measurement, and this number should not be greater than the number of available SPUs of the first node. Optionally, the number of sensing measurement processing units required for sensing measurement may be related to at least one of the following:

[0250] the sensing range (the sensing range corresponding to the sensing measurement requirement); the format of the sensing signal; the number of transmissions of the sensing signal / sensing signal group / sensing signal set; the number of repetitions of the sensing signal; the number of repetitions of the sensing signal group; the number of repetitions of the sensing signal set; the period of the sensing signal; the period of the sensing signal group; and, the period of the sensing signal set.

[0251] The number of repetitions may refer to the number of repeated transmissions of the sensing signal / signal group / signal set. For a signal group, the number of repetitions may also be the number of sensing signals in one signal group or the number of identical sensing signals in this signal group. For a signal set, the number of repetitions may also be the number of signal groups included in one signal set or the number of identical signal groups among the included signal groups.

[0252] In an optional implementation, the number of sensing measurement processing units required for sensing measurement may be related to at least one of the sensing range and the format of the sensing signal. For example, the sensing signal in the sensing configuration includes a CP and a sub physical signal (e.g., a reference signal), wherein the sensing distance corresponding to the length of the CP is d1 meters, and the parameter related to the sensing range in the second parameter is the length corresponding to the length of the CP. The first node may obtain the measurement results within the sensing distance corresponding to the length of the CP by single-window detection, and the number of sensing measurement processing units required for sensing measurement may be Y1. For another example, the sensing signal in the sensing configuration includes a CP and a sub physical signal, wherein the sensing distance corresponding to the length of the CP is d1 meters, and the parameter related to the sensing range in the second parameter is the length corresponding to 2 times of the length of the CP, i.e., 2*d1 meters, which is greater than one time of the length of the CP. The second node needs to obtain the measurement results within two times of the length of the CP by a multi-window detection algorithm, the number of sensing measurement processing units required for sensing measurement is Y2, and Y2 is greater than Y1.

[0253] In an implementation, the number of sensing measurement processing units required for sensing measurement is related to the number of repetitions of the sensing signal and / or the number of repetitions of the sensing signal set and / or the period of the sensing signal and / or the period of the sensing signal set. For example, the larger the number of repetitions of the sensing signal, the larger the number of sensing measurement processing units required for sensing measurement is. For example, the larger the number of repetitions of the sensing signal set, the larger the number of sensing measurement processing units required for sensing measurement is.

[0254] Optionally, the second parameter may also include the indices or IDs of the sensing signals corresponding to the measurement quantity reporting (that is, the first node is expected to report the sensing measurement results corresponding to the indices or IDs), and the time frequency resource occupied by the measurement quantity reporting corresponding to the index or ID of the sensing reference signal. For example, the second parameter includes an offset K2 between the sensing configuration and the sensing measurement quantity reporting, as shown in FIGS. 8A to 8C, wherein the offset may be a slot offset, a symbol offset or a sampling point offset. For example, K2 represents the interval between the slot where the sensing configuration information is located and the slot where the scheduled sensing measurement quantity reporting is located. If the slot where the sensing configuration information is located is the slot X, its scheduled sensing measurement quantity reporting should be transmitted in the slot X+K2.

[0255] Optionally, the value of the offset K2 is related to at least one of the capability of the first node and the sensing measurement requirements. Optionally, the value of the offset K2 may be determined by at least one of the following:

[0256] the UE's computing capability for the sensing signal, the sensing measurement processing units occupied or required by the corresponding sensing measurement, the number of sensing signals on which sensing measurement is based, the number of sensing signal groups on which sensing measurement is based, and the number of sensing signal sets on which sensing measurement is based. For example, when the UE's computing capability for the sensing signals is lower, the value of K2 may be larger.

[0257] In an optional implementation, the value of the offset K2 is related to the capability of the first node. The higher the capability of the first node, the smaller the value of K2 may be. Optionally, the value of K2 may be related to the sensing measurement processing time of the first node. When the first node is triggered to report the sensing measurement quantity by the sensing configuration, the first node should provide a valid sensing measurement report for the nthtriggered report. Optionally, the first symbol (i.e., the first time unit, e.g., the first uplink symbol) carrying the corresponding sensing measurement quantity report should not be earlier than the symbol (the third resource). Optionally, the first symbol (e.g., the first uplink symbol) carrying the nthsensing measurement quantity report should not be earlier than the symbol (the second resource). Optionally, by taking the first symbol being an uplink symbol as an example, if the first uplink symbol carrying the corresponding sensing measurement quantity report contains the influence of timing advance, the first uplink symbol should not be earlier than the symbol ; and, if the first uplink symbol carrying the nthsensing measurement quantity report contains the influence of timing advance, the uplink symbol should not be earlier than the symbol .

[0258] The is defined as the next symbol with its CP starting after Z (a first number of) symbols (or the time occupied by Z symbols or the number of sampling points) after the end of the last symbol of the sensing configuration scheduling the sensing measurement quantity reporting, i.e., the first symbol after the Z symbols, e.g., the first uplink symbol. By taking the first node being a UE as an example, in the example shown in FIG. 8D, the first node may report its capability information (UE capability) and may then receive the sensing configuration (Sensing Config). Optionally, by parsing the obtained sensing configuration, the first node may determine the possible first symbol for reporting the corresponding sensing measurement report, for example, the uplink symbol corresponding to the T1 position in FIG. 8D. As a specific example, the starting position of the CP of the symbol is the symbol at T1. In the example of FIG. 8D, T2 represents the possible earliest reporting time when the first node reports the first sensing measurement report, T3 represents the starting time of the first sensing measurement reporting occasion configured for the first node, and T3' represents the starting time of the configured last sensing measurement reporting occasion.

[0259] The is defined as the first symbol (e.g., the first uplink symbol) with its CP starting after Z' (a second number of) symbols (or the time occupied by Z' symbols or the number of sampling points) after the end of the last symbol of the nthsensing signal scheduled by the sensing configuration, e.g., the first uplink symbol (e.g., the uplink symbol corresponding to the T2 position in FIG. 8D). As a specific example, the starting position of the CP of the symbol is the symbol at T1. In some implementations, if it is assumed that the sensing configuration schedules N sensing signals, the node may perform measurement based on the N sensing signals, or may perform measurement based on some of the N sensing signals. For example, the sensing configuration schedules 20 sensing signals, the first sensing measurement is based on the 1stto 10thsensing signals, and the second measurement is based on the 11thto 20thsensing signals. In some implementations, if the sensing configuration schedules N sensing signals and the indices of the sensing signals are from 0 to N-1, the index of the nthsensing signal is n-1, where the value of n satisfies the following condition: . The measurement based on the nthsensing signal may be a measurement performed for one time based on each sensing signal in the sensing signals having indices from 0 to n-1 respectively, and the measurement based on the nthsensing signal may also be at least one measurement performed based on all sensing signals in the sensing signals having indices from 0 to n-1. In some implementations, if the sensing configuration schedules N sensing signals and the indices of the sensing signals may be from 1 to N, the index of the nthsensing signal is n, where the value of n satisfies the following condition: . The measurement based on the nthsensing signal may be a measurement performed for one time based on each sensing signal in the sensing signals having indices from 1 to n respectively, and the measurement based on the nthsensing signal may also be at least one measurement performed based on all sensing signals in the sensing signals having indices from 1 to n.

[0260] The shown in FIG. 8D is defined as the first uplink symbol (for example, the uplink symbol corresponding to the T2' position in FIG. 8D) with its CP starting after Z'' symbols (or the time occupied by Z'' symbols or the number of sampling points) after the end of the last symbol of the first sensing signal scheduled by the sensing configuration. As a specific example, the starting position of the CP of the symbol is the symbol at T2'. That is, the value of the offset K2 should take into account the time for the second node to demodulate and decode the configuration information and the time for the second node to measure the sensing signal. The is the when the nthsensing signal is the first sensing signal.

[0261] Optionally, the values of the Z and Z' may be related to at least one of the following parameters:

[0262] the sub-carrier spacing, the type of the first node, the computing capability of the first node for the sensing signal, the sensing measurement processing units occupied or required by the corresponding sensing measurement (i.e., the resources for the first node occupied by sensing measurement), the number of sensing signals on which sensing measurement is based (i.e., sensing signals associated with sensing measurement), the number of sensing signal sets on which sensing measurement is based, the format or type of the sensing signal, and the sensing measurement requirements (e.g., the first node is notified in the configuration information to report the sensing measurement results within a certain distance).

[0263] In some embodiments, the values of Z and / or Z' are obtained by a method of looking up a table. The values of Z and / or Z' may be obtained by looking up a table. For example, in the example shown in Table 1, is Numerology, representing the sub-carrier spacing. In some implementations, the values of Z and / or Z' are related to the type of the first node and / or the computing / processing capability of the first node for the sensing signal. For example, when the first node is a handheld terminal and / or the computing capability of the first node is lower, the values of Z and / or Z' may be larger; and, when the first node is a special terminal and / or the computing capability of the first node is higher, for example, when the first node is a customer terminal device, or a customer premise equipment (CPE), the values of Z and / or Z' may be smaller.

[0264]

[0265] As an optional implementation, the values of Z and / or Z' may be related to the number of sensing signals / sensing signal groups / sensing signal sets on which sensing measurement is based. For example, if the number of sensing signals / sensing signal groups / sensing signal sets on which sensing measurement is based is larger, the values of Z and / or Z' may be larger; and, if the number of sensing signals / sensing signal groups / sensing signal sets on which sensing measurement is based is smaller, the values of Z and / or Z' may be smaller.

[0266] Optionally, the values of Z and / or Z' are related to the format or type of the sensing signal. For example, when the sensing distance corresponding to the format or type of the sensing signal is larger, the values of Z and / or Z' may be smaller; and, when the sensing distance corresponding to the format or type of the sensing signal is larger, the values of Z and / or Z' may be larger.

[0267] Optionally, the values of Z and / or Z' may be related to the sensing measurement requirements. For example, when the distance range required for sensing measurement is smaller, the values of Z and / or Z' may be smaller; and, when the distance range required for sensing measurement is larger, the values of Z and Z' may be larger.

[0268] As an optional implementation, the values of Z and / or Z' may be related to the sensing measurement processing units occupied or required by the corresponding sensing measurement, that is, the values are related to the resources for the first node to be occupied by sensing measurement. For example, when the number of sensing measurement processing units occupied or required by the corresponding sensing measurement is smaller, the values of Z and / or Z' may be smaller; and, the number of sensing measurement processing units occupied or required by the corresponding sensing measurement is larger, the values of Z and / or Z' may be larger.

[0269] In some optional implementations, the values of Z and / or Z' may be related to at least one of the format or type of the sensing signal and the sensing measurement requirements. In some optional implementations, the values of Z and / or Z' may be related to the format of the sensing signal. For example, if the length of a sub physical signal in the sensing signal is larger, the corresponding values of Z and / or Z' may be larger. For another example, if the number of sub physical signals in the sensing signal is larger, the corresponding values of Z and / or Z' may be larger.

[0270] In some optional implementations, the values of Z and / or Z' may be related to the sensing measurement requirements. For example, if the sensing distance range required for sensing measurement is larger, the corresponding values of Z and / or Z' may be larger. For another example, if the sensing speed range required for sensing measurement is larger, the corresponding values of Z and / or Z' may be larger. For another example, if the sensing angle range required for sensing measurement is larger, the corresponding values of Z and / or Z' may be larger. For another example, if the sensing accuracy required for sensing measurement is higher, the corresponding values of Z and / or Z' may be larger, wherein the sensing accuracy includes at least one of sensing distance accuracy, sensing angle accuracy and sensing speed accuracy.

[0271] In some optional implementations, the values of Z and / or Z' may be related to the format or type of the sensing signal and the sensing measurement requirements. For example, when the sensing distance corresponding to the format or type of the sensing signal is less than the distance range required for sensing measurement, the values of Z and / or Z' may be larger; and, when the sensing distance corresponding to the format or type of the sensing signal is greater than the distance range required for sensing measurement, the values of Z and / or Z' may be smaller. As an optional example, when the sensing signal includes a CP and a sub physical signal, the corresponding valid sensing range is the distance corresponding to the length of the CP; and, when the distance range required for sensing measurement is greater than the distance corresponding to the CP, the node needs to select a detection algorithm with higher computing complexity, so more processing time is needed, and the values of Z and / or Z' may be larger. That is, during the configuration of the first node, the value of K2 should be relatively large. For example, the first node is a UE, the second node is a base station, and the base station needs to reserve more sensing signal processing time for the UE while configuring K2.

[0272] In an optional implementation, the method of calculating Z' may be related to the format of the sensing signal. By taking the length of the sub physical signal in the sensing signal as an example, if the length of the sub physical signal in the sensing signal is larger, the value of Z' is larger; and, if the length of the sub physical signal in the sensing signal is smaller, the value of Z' is smaller. For example, in an indoor intrusion detection scenario, the sensing node needs to sense in a smaller range, so the sub physical signal in the sensing signal may be short. Thus, the processing time for each sub physical signal will be shorter, and the value of Z' is smaller. For another example, in an outdoor UAV detection scenario, the sensing node needs to sense in a lager range, so the sub physical signal in the sensing signal may be long. Thus, the processing time for each sub physical signal will be longer, and the value of Z' is larger. Similarly, if the number of sub physical signals in the sensing signal is larger, the value of Z' is larger; and, if the number of sub physical signals in the sensing signal is smaller, the value of Z' is smaller.

[0273] In an optional implementation, the method of calculating Z' may be related to the sensing measurement requirements. By taking the estimation accuracy of sensing measurement as an example, if the estimation accuracy is higher, the value of Z' is larger; and, if the estimation accuracy is lower, the value of Z' is larger. For example, in a UAV sensing scenario, the node needs to identify static and / or moving UAVs and need to identify objects accurately; and the required estimation accuracy is higher, and the value of Z' may be larger. For another example, in a tourist flow monitoring scenario, the node mainly needs to identify persons / bicycles moving at a low speed, and may determine sensing results by identifying the strength of the received signals; and the required estimation accuracy is lower, and the value of Z' may be smaller. The estimation accuracy of sensing measurement may include at least one of sensing distance accuracy, sensing angle accuracy and sensing speed accuracy.

[0274] In an optional implementation, the method of calculating Z' may be related to the format or type of the sensing signal. For example, the calculation of Z' may be related to the length of the CP of the sensing signal and / or the length of at least one sub physical signal in the sensing signal, and the sensing measurement distance in the sensing measurement requirement. The length of at least one sub physical signal in the sensing signal may be the lengths of one or more sensing signals in the sensing signal; or, when the sensing signal includes a plurality of sub physical signals, the length may refer to the length of a specific sub physical signal in the sensing signal, and the specific sub physical signal may be the first sub physical signal or repetitive sub physical signals. Optionally, the repetitive sub physical signals may be sub physical signals having the same signal length. For example, the sensing signal includes a sub physical signal 1, a sub physical signal 2 and a sub physical signal 3, wherein the signal 1 and the signal 2 have the same length, and the length may be the length of the signal 1.

[0275] The length of the CP / sub physical signal and / or the sensing distance in the sensing measurement requirements may implicitly determine the target detection method used by the first node (e.g., the UE), i.e., what calculation scheme adopted by the first node when performing sensing measurement based on the received signal. For example, the first node may adopt single-window detection or multi-window detection. Different detection methods have different calculation complexities and thus correspond to different calculation times.

[0276] In an optional implementation, the format of the sensing signal may be shown in FIG. 6A, the sensing signal includes 1 sub physical signal, and Z' may be calculated in the following way:

[0277] (Formula 1)

[0278] where is obtained by rounding down the quotient of the sensing distance and the distance corresponding to the length of the CP of the sensing signal, the sensing distance here is the distance corresponding to the sensing requirement, for example, being obtained based on the parameter related to the sensing range in the sensing configuration; represents the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this calculation; represents the number of sampling points corresponding to one sub physical signal; and, represents the time for processing one sensing signal (or sensing signal group / sensing signal set), for example, the number of symbols corresponding to the time required to process one sensing signal (or sensing signal group / sensing signal set).

[0279] It is to be noted that the number of sampling points corresponding to one sub physical signal refers to the number of sampling points of this sub physical signal when the receiver receives the signal. However, when the number of sampling points is used to represent the length of one sub physical signal, the number of sampling points refers to the number of sampling points (denoted by number A) of the time domain signal corresponding to this sub physical signal in the base band when the transmitter sends this sub physical signal. When the transmitter sends the sub physical signal, the time domain signal corresponding to the base band is modulated to a carrier (e.g., an OFDM sub-carrier) and then sent. In the receiving process of the receiver, the received signal is sampled to obtain a signal corresponding to the received signal after time domain sampling. The number of sampling points (denoted by number B) in this process may be the same as or different from the number A.

[0280] In an optional implementation, the format of the sensing signal may be shown in FIG. 6B, the sensing signal of this format includes 2 sub physical signals, and Z' may be calculated in the following way:

[0281] (Formula 2)

[0282] where is obtained by rounding down the quotient of the sensing distance and the distance corresponding to the sensing signal (the distance corresponding to the sensing signal may be the sensing / detection distance corresponding to the sub physical signal 1, or the distance corresponding to the CP, or the distance corresponding to the sub physical signal 1 and the CP); represents the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this calculation; represents the number of sampling points corresponding to one sub physical signal; and, represents the number of symbols corresponding to the time required to process one sensing signal (or sensing signal group / sensing signal set).

[0283] In an optional implementation, if it is assumed that the sensing signal includes R sub physical signals where R≥2, the method of calculating Z' may be as follows:

[0284] (Formula 3)

[0285] where is obtained by rounding down the quotient of the sensing distance and the distance corresponding to the sensing signal (the distance corresponding to the sensing signal may be the sensing / detection distance corresponding to the sub physical signal 1, or the distance corresponding to the CP, or the distance corresponding to the sub physical signal 1 and the CP); represents the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this calculation; represents the number of sampling points corresponding to one sub physical signal; and, represents the number of symbols corresponding to the time required to process one sensing signal (or sensing signal group / sensing signal set).

[0286] In an implementation, the value of Z' is related to the angle estimation accuracy of sensing measurement. Optionally, the type of the angle estimation accuracy of sensing measurement may be preset. For example, it is defined that the type of the angle estimation accuracy of sensing measurement is classified into at least two types. By taking the type of the angle estimation accuracy including three types (i.e., type 1 to type 3) as an example, the three accuracy types are denoted by Type I, Type II and Type III, respectively. It means that Type I corresponds to a high-accuracy angle estimation requirement, Type II corresponds to a medium-accuracy angle estimation requirement and Type III corresponds to a low-accuracy angle estimation requirement. In the actual sensing measurement, different types of angle estimation accuracy may correspond to different receiver detection algorithms. For example, Type I corresponds to a super-resolution angle algorithm, Type II corresponds to a non-super-resolution angle algorithm (e.g., a sum-difference beam estimation angle algorithm), and Type III corresponds to a sum beam based angle estimation algorithm. Different algorithms correspond to different complexities and require different processing times.

[0287] Optionally, if the accuracy requirement is higher, the value of Z' may be larger. For example, when the type of the angle estimation accuracy of sensing measurement is Type I, the value of Z' may be larger, for example, the value of Z' may be obtained by adding or multiplying by on the basis of the above Formula 1, Formula 2 and Formula 3; when the type of the angle estimation accuracy of sensing measurement is Type II, the value of Z' may be small, for example, the value of Z' may be obtained by adding or multiplying by on the basis of the above Formula 1, Formula 2 and Formula 3; and, when the type of the angle estimation accuracy of sensing measurement is Type III, the value of Z' may be smaller, for example, the value of Z' may be obtained by adding or multiplying by on the basis of the above Formula 1, Formula 2 and Formula 3, where , and .

[0288] As an alternative, the values of Z and / or Z' corresponding to different sensing measurement requirements and / or formats of sensing signals may be determined by looking up a table. For example, the sensing related configuration may include the information related to sensing measurement requirements and / or the related information of the format of the sensing signal. The first node may determine the values of Z and / or Z' corresponding to this configuration by looking up a table according to the information in the configuration, and then determine the first resource for reporting the sensing measurement report.

[0289] Optionally, before acquiring the sensing related configuration, the first node reports its own capability information to the second node, for example, the number of sensing measurement processing units that can be supported simultaneously in the current component carrier, and / or the number of sensing measurement processing units that can be supported simultaneously in all component carriers.

[0290] In an optional implementation, the sensing measurement processing capability of the first node is , i.e., the maximum number of SPUs that can be supported by the first node. If there areLSPUs occupied by the sensing measurement reporting on a certain OFDM symbol, the first node has available SPUs, that is, the number of unoccupied SPUs for the first node is . If the first node is configured with N sensing measurement reports on the above OFDM symbol (for example, being configured to send sensing measurement reports corresponding to N sensing signals) (where the nthsensing measurement report needs to occupy sensing measurement processing units), the first node may not need to update the sensing measurement quantity reporting with a lower priority, that is, N-M sensing measurement reports with lower priorities may not be transmitted, where , and is the maximum value satisfying the following condition: . In other words, the first node may determine, according to the priorities (sensing measurement priorities) of sensing measurement reports and the number of currently unoccupied SPUs for the first node, M sensing measurement reports with higher priorities that can be reported by the first node at most.

[0291] Optionally, the method of determining the sensing measurement priority may be related to at least one of the following parameters:

[0292] a parameter related to the sensing signal; and, a parameter related to the sensing measurement quantity reporting and / or sensing measurement requirements.

[0293] In some optional implementations, the sensing measurement priority may be related to the sensing measurement priority value. For example, one sensing measurement corresponds to one sensing measurement priority value, and a smaller sensing measurement priority value corresponds to a higher priority. Optionally, the priority value corresponding to the sensing measurement may be configured in the configuration information, i.e., being explicitly or implicitly determined according to the related information in the configuration information. For example, the sensing configuration includes the index of at least one sensing signal on which the sensing measurement is based and the priority value corresponding to this index (or the related information of the priority value, e.g., scenario indication information, different scenarios corresponding to different priority values).

[0294] In some optional implementations, the sensing measurement priority is related to the period of the sensing signal. For example, the sensing signal is aperiodic, the corresponding sensing measurement has a smaller priority value and a higher priority.

[0295] In some optional implementations, the sensing measurement priority is related to the index or ID of the sensing signal and / or the transmitting moment of the sensing signal. For example, if the index and ID value of the sensing signal is smaller and / or the transmitting moment of the sensing signal is earlier, the corresponding sensing measurement has a smaller priority value and a higher priority. The method of calculating the priority may be applied to, but not limited to, scenarios with lower delay requirements, for example, scene tourist flow monitoring, or trajectory tracking related scenarios, e.g., UAV trajectory drawing. For another example, if the index and ID value of the sensing signal is larger and / or the transmitting moment of the sensing signal is later, the corresponding sensing measurement has a smaller priority value and a higher priority. The above method of calculating the priority is applied to scenarios with higher delay requirements, such as intelligent traffic scenarios.

[0296] In some optional implementations, the sensing measurement priority is related to the sensing scenario / sensing requirement. For example, in scenarios with higher delay requirements, such as intelligent traffic scenarios and Internet of Vehicles scenarios, the corresponding sensing measurement has a higher priority; while in scenarios with lower delay requirements, such as scene tourist flow monitoring scenarios, the corresponding sensing measurement has a lower priority. As a specific example, the sensing configuration includes a parameter related to the sensing scenario. When the value of the parameter is 0, it indicates that the delay requirement is higher; and, when the value of the parameter is 1, it indicates that the delay requirement is lower.

[0297] In some optional implementations, the sensing measurement priority value may be calculated by a formula. For example, the sensing measurement priority value may be calculated by the following formula:

[0298]

[0299] whereyrepresents the parameter related to the period of the sensing signal,krepresents the parameter related to the type of the sensing measurement quantity,crepresents the index of the serving cell,srepresents the index of the sensing signal corresponding to the sensing measurement,qrepresents the parameter related to the sensing delay requirement, the value of is related to the high-layer parameter maxNrofServingCells (the maximum number of serving cells), and the value of is related to the high-layer parameter maxNrofCSI-ReportConfigurations (the maximum number of report configurations).

[0300] In some optional implementations, the sensing measurement priority value may be calculated by a formula. For example, the sensing measurement priority value is expressed as:

[0301]

[0302] Optionally, the sensing measurement priority value may also be related to some parameters in the above calculation formula. Optionally, some parameters may at least include theq. The specific value ofqis directly indicated in the sensing configuration, or may be determined according to the related parameter in the configuration.

[0303] In an optional implementation, the number of sensing measurement processing units required for sensing measurement is related to at least one of the following: the format of sensing signals associated with the sensing measurement reporting, the number of sensing signals (or sensing signal groups / sensing signal sets) associated with the sensing measurement reporting, and the sensing measurement requirements (e.g., the second node is notified in the configuration information to report the sensing measurement results within a certain distance).

[0304] As an optional implementation, the method of calculating the number (denoted by ) of sensing measurement processing units required for sensing measurement may be related to the format of the sensing signal associated with sensing measurement. For example, if the number of sub physical signals in the sensing signal is larger, the corresponding is larger. For another example, if the length of sub physical signals in the sensing signal is larger, the corresponding is larger.

[0305] As an optional implementation, the method of calculating may be related to the number of sensing signals (or sensing signal groups / sensing signal sets). For example, if the number of sensing signals (or sensing signal groups / sensing signal sets) is larger, the corresponding is larger.

[0306] In an optional implementation, the method of calculating may be related to the sensing measurement requirements. For example, if the speed required for sensing is higher, the corresponding is larger; and, if the speed required for sensing is lower, the corresponding is smaller. For another example, if the accuracy required for sensing is higher, the corresponding is larger; and, if the accuracy required for sensing is lower, the corresponding is smaller.

[0307] In an implementation, the corresponding may be defined according to the requirements for different types of sensing measurement requirements. By taking the angle estimation accuracy of sensing measurement as an example, it is defined that the type of the angle estimation accuracy of sensing measurement is classified into at least two types, for example, the above Type I, Type II and Type III. When the type of the angle estimation accuracy of sensing measurement is Type I, may have a value of ; when the type of the angle estimation accuracy of sensing measurement is Type II, may have a value of ; and, when the type of the angle estimation accuracy of sensing measurement is Type III, may have a value of , where .

[0308] As an optional implementation, the method of calculating may be related to the format of the sensing signal associated with sensing measurement and the sensing measurement requirements. For example, it may be related to the length of the CP of the sensing signal and / or the length of repetitive sub physical signals in the sensing signal, and the sensing measurement distance in the sensing measurement requirements. The length of the CP / sub physical signal and the sensing distance implicitly determine the detection method used by the UE, for example, single-window detection or multi-window detection. Different detection methods have different calculation complexities and thus correspond to different calculation times. Optionally, the first node may calculate the corresponding to each sensing measurement by itself according to the format or type of the sensing signal. Of course, the corresponding to each sensing measurement may also be indicated by the sensing configuration.

[0309] In an optional implementation, the format of the sensing signal may be shown in FIG. 6A, the number of sub physical signals is 1, and the method of calculating may be as follows:

[0310] (Formula 4)

[0311] where is obtained by rounding down the quotient of the sensing distance and the distance corresponding to the length of the CP; represents the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this calculation; is the number of sampling points corresponding to one sub physical signal; and, represents the number of sensing measurement processing units corresponding to one sensing signal (or sensing signal group / sensing signal set). In an implementation, may be the number of sampling points included in a single OFDM symbol (without CP). In an implementation, the value of may be related to the sensing distance accuracy. For example, if the distance accuracy is lower, the value of is larger. The physical meaning is that, if the corresponding distance between two adjacent sampling points is smaller, the required sampling frequency is increased, and the number of sampling points for a single sub physical signal needs to be increased.

[0312] In an optional implementation, the format of the sensing signal may be shown in FIG. 6B, the number of sub physical signals included in the sensing signal is 2, the method of calculating may be as follows:

[0313] (Formula 5)

[0314] where is obtained by rounding down the quotient of the sensing distance (sensing requirement) and the distance corresponding to the sub physical signal 1; represents the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this sensing computation; is the number of sampling points included in a single OFDM symbol (without CP); and, represents the number of symbols corresponding to the time required to process one sensing signal (or sensing signal group / sensing signal set). In an optional implementation, the number of sub physical signals included in the sensing signal is R, and the method of calculating may be as follows:

[0315] (Formula 6)

[0316] where is obtained by rounding down the quotient of the sensing distance (sensing requirement) and the distance corresponding to the sub physical signal 1 (or the sub physical signal 2); represents the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this sensing computation; is the number of sampling points included in a single OFDM symbol (without CP); and, represents the number of symbols corresponding to the time required to process one sensing signal (or sensing signal group / sensing signal set). Optionally, the value of may also be related to the sensing distance accuracy. For example, if the distance accuracy is higher, the value of is larger. Optionally, the value of may also be obtained by using at least one of the sensing speed and the sensing speed range in the information related to sensing measurement requirements and / or the sensing speed accuracy.

[0317] By taking R=3 as an example, for example, when the sensing speed corresponds to positive 20 m / s and / or negative 20 m / s or the sensing speed range corresponds to negative 20 m / s to positive 20 m / s, the sensing speed accuracy requirement is 1 m / s, one sensing signal is transmitted in each slot, and the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this calculation may be 40. For another example, when the sensing speed corresponds to positive 20 m / s and / or negative 20 m / s or the sensing speed range corresponds to negative 20 m / s to positive 20 m / s, the sensing speed accuracy requirement is 0.5 m / s, one sensing signal is transmitted in each slot, and the number of sensing signals (or sensing signal groups / sensing signal sets) corresponding to this calculation may be 80.

[0318] In an implementation, the value of is related to the angle estimation accuracy of sensing measurement, and the type of the angle estimation accuracy of sensing measurement may be preset, still taking the Type I, Type II and Type III described above as an example. When the type of the angle estimation accuracy of sensing measurement is Type I, the value of may be larger, for example, the value of may be obtained by adding or multiplying by on the basis of the above Formula 4, Formula 5 and Formula 6; when the type of the angle estimation accuracy of sensing measurement is Type II, the value of may be small, for example, the value of may be obtained by adding or multiplying by on the basis of the above Formula 4, Formula 5 and Formula 6; and, when the type of the angle estimation accuracy of sensing measurement is Type III, the value of may be smaller, for example, the value of may be obtained by adding or multiplying by on the basis of the above Formula 4, Formula 5 and Formula 6, where , and .

[0319] Some related descriptions about the sensing signal or some processing modes about the sensing signal in the above various embodiments of the present disclosure can also be applied to the sensing signal group or sensing signal set.

[0320] In the embodiment of the present disclosure, in the processing of reporting based on the configuration information, as shown in FIG. 7, the first node may perform the computing resource conflict judgment described above, for example, determining, according to the number of SPUs required for each measurement report and the number of available SPUs of the first node, whether all (or all configured) sensing measurement reports can be reported, and determining to report which sensing measurement reports based on the priority information in the case where all sensing measurement reports cannot be reported. Optionally, the first node may also perform time conflict judgment, i.e., determining the reporting time of the sensing measurement quantity.

[0321] As an optional scheme provided in the embodiment of the present disclosure, a method for determining and feeding back a sensing measurement quantity reporting time may include: receiving, by the first node, a sensing related configuration, and calculating, by the second node, sensing measurement reporting times based on the sensing related configuration and selecting a sensing measurement reporting time. The sensing related configuration may include a parameter related to a time frequency resource for the sensing measurement reporting. For example, the sensing related configuration may include a time domain resource for the sensing measurement reporting.

[0322] In an optional implementation, the time domain resource may include one or more sensing measurement reporting occasions (SROs). One sensing measurement reporting occasion corresponds to one OFDM symbol or a plurality of continuous OFDM symbols. For example, one sensing measurement reporting occasion includes one physical uplink traffic channel, e.g., a physical uplink shared channel, and one PUSCH may occupy one or more continuous OFDM symbols.

[0323] In an optional implementation, the first node may randomly select, from a plurality of configured sensing measurement reporting occasions, one or more sensing measurement reporting occasions for reporting sensing measurement quantities, i.e., sending sensing measurement reports to the second node. Optionally, the second node performs monitoring and decoding on the resources corresponding to a plurality of sensing measurement reporting occasions, to obtain one or more results. Optionally, the second node may merge the plurality of received results to improve the reliability of data transmission. For example, the second node receives time domain signals corresponding to two or more sensing signals, obtain two or more sensing signals based on the time domain signals, and obtains an intersection set or union set of the plurality of sensing signals. For another example, the second node receives time domain signals corresponding to two or more sensing results, summates or averages a plurality of time domain signals / a plurality of channel estimation results to increase the signal to noise ratio, and obtains a sensing result.

[0324] As an optional implementation, upon obtaining the sensing related configuration, the first node may calculate the sensing measurement reporting time. Optionally, the first node may determine the sensing measurement reporting time according to the time domain resource of the sensing related configuration (i.e., the resource occupied by the sensing related configuration), the time domain resource of the sensing signal (the resource where the sensing signal sent by the transmitting node is located), the decoding time of the sensing related configuration (the parsing time required by the first node after obtaining the sensing related configuration) and the time required for sensing measurement (the time to obtain the sensing measurement result based on the received signal). Optionally, the first node may select, from the configured reporting occasions, one or more reporting times not later than its determined reporting time to send a measurement report.

[0325] As an optional implementation, the first node determine, according to the sensing measurement reporting resource in the sensing related configuration and the sensing measurement reporting time calculated by the first node, the sensing measurement reporting occasion actually used by the sensing measurement report.

[0326] In an optional implementation, the first node selects the sensing measurement reporting time according to the determined sensing measurement reporting occasion actually used by the sensing measurement report. The first node may notify the second node of the selected sensing measurement reporting occasion actually used by the sensing measurement reporting.

[0327] As an example, as shown in FIG. 8D, the first node determine the time T1 based on the decoding time of the sensing related configuration and the sensing configuration information (for example, as shown in FIG. 9, the sensing related configuration includes the related configurations of two sensing signals, and each sensing signal occupies 1 OFDM symbol (with a CP)). The first node completes configuration after receiving the sensing related configuration, and the parsed time is T1. For example, T1 may be the starting position of the CP of a certain symbol including a CP. Further, the first node may determine the time T2 based on the sensing signal and the sensing measurement processing time (for example, T2 may be the starting position of a certain symbol including a CP). According to the T1 and T2, the first node determines the earliest moment of the possible reporting time of sensing measurement, for example, the later moment in T1 and T2. The first node determines, based on the earliest moment (e.g., T2) of the possible reporting time of sensing measurement and the sensing measurement reporting occasion, the sensing measurement reporting occasion of the actually transmitted sensing measurement result. For example, P sensing measurement reporting occasions are configured in the sensing configuration, where Q sensing measurement reporting occasions are later than the earliest moment of the possible reporting time of sensing measurement. The first node reports the information related to the Q sensing measurement reporting occasions, e.g., the indices or IDs of the reporting occasions; or, the first node reports the index or ID corresponding to the first sensing measurement reporting occasion in the Q sensing measurement reporting occasions; or, the first node reports the indices or IDs corresponding to any one or more sensing measurement reporting occasions in the Q sensing measurement reporting occasions. The second node may receive the sensing measurement report in the reporting occasion notified by the first node.

[0328] Optionally, it is assumed that the starting moment (e.g., T3' in FIG. 8D) of the first symbol of the configured last sensing measurement reporting occasion is earlier than the earliest moment (e.g., T2) of the possible reporting time of sensing measurement, that is, the last reporting occasion does not satisfy the possible earliest reporting time determined by the first node. At this time, the first node may apply for an uplink traffic in one or more reporting occasions in the available sensing measurement reporting occasions, for example, sending a scheduling request or buffer status report. For example, when the starting moment of the first sensing measurement reporting occasion is later than T1, the first node may apply for an uplink traffic in the first reporting occasion in the available sensing measurement reporting occasions, i.e., sending a resource request for requesting a resource for transmitting the measurement report, wherein the application information of the uplink traffic may include the time when the uplink traffic is expected to be scheduled by the base station, i.e., the time when the first node is expected to report.

[0329] In an optional implementation, it is assumed that the sensing configuration corresponds to N sensing signals, and the first node reports the measurement quantities corresponding to first M sensing signals in at least one of a plurality of sensing measurement reporting occasions, where M is less than N. For example, the sensing configuration corresponds to N sensing signals, the starting moment (T3') of the first symbol of the last sensing measurement reporting occasion is earlier than the earliest moment (T2) of the possible reporting time of sensing measurement. If the first node determines, according to one or more sensing measurement reporting occasions (e.g., the last sensing measurement reporting occasion) in the sensing related configuration, the number M of sensing signals corresponding to the sensing measurement that can be completed before the sensing measurement reporting occasion, the first node reports the sensing measurement results corresponding to first M sensing signals in the measurement reporting occasion. In other words, if the first node may obtain at least one sensing measurement result before at least one reporting occasion in the configured reporting occasions, the at least one sensing measurement result may be reported first in the at least one reporting occasion. Optionally, during reporting, the first node may also send a traffic application for applying for reporting resources for N-M sensing measurement results.

[0330] Optionally, if the number of sensing signals corresponding to the sensing configuration is 1 and the starting moment (T3') of the first symbol of the last sensing measurement reporting occasion is earlier than the earliest moment (T2) of the possible reporting time of sensing measurement, the first mode may ignore the sensing configuration, that is, the first node may not perform sensing measurement and sensing reporting.

[0331] Optionally, if the number of sensing signals corresponding to the sensing configuration is greater than 1 and the starting moment (T3') of the first symbol of the last sensing measurement reporting occasion is earlier than the earliest moment (T2) of the possible reporting time of sensing measurement, the first node may calculate the processing time corresponding to the first sensing signal, and calculate the earliest time (T2') of the sensing measurement quantity reporting corresponding to the first sensing signal according to the processing time corresponding to the first sensing signal and the time domain resource for the first sensing signal. When T2' is earlier than T3, the first node reports the sensing measurement quantity obtained based on the first sensing signal on the first sensing measurement reporting occasion, and also optionally applies for an uplink traffic on the first sensing measurement reporting occasion. When T2' is later than T3, the first node applies for an uplink traffic in the first sensing measurement reporting occasion.

[0332] Optionally, if the starting moment (T3') of the first symbol of the last sensing measurement reporting occasion is earlier than the earliest moment (T1) of demodulation / decoding of the sensing configuration, the first node ignores the sensing configuration.

[0333] In an optional implementation, the sensing measurement report may include a sensing related measurement quantity, and the measurement quantity may include at least one of the following: a measurement result related to the channel experienced by the sensing signal, a measurement result related to time, a measurement result related to a sampling point, and a measurement result related to power. For example, the sensing related measurement quantity may include the time or delay, or the relative time or relative delay of each path in at least one path in the channel experienced by the sensing signal. For another example, the sensing related measurement quantity may include the channel response power or an average of channel response powers of each path in the at least one path. For another example, the sensing related measurement quantity may include the index of the sampling point of the at least one path. For another example, the sensing related measurement quantity may include the index of the sampling point of the path, in the at least one path, having a time or delay or a relative time or relative delay within a preset range. In addition, it is to be noted that, the "uplink" and / or "downlink" descried in the optional embodiment of the present disclosure is a relative concept. It can be interpreted that one node sending a sensing measurement report to another node is uplink, i.e., the transmission direction from the report sender to the report receiver is uplink, and the transmission direction from the report receiver to the report sender is downlink.. When the report sender is a user equipment and the report receiver is a base station, the uplink / downlink in the embodiment of the present disclosure has the same meaning as the uplink / downlink in the current communication system.

[0334] It is to be noted that the optional schemes provided in the above various embodiments of the present disclosure can be implemented separately, and the embodiments or the steps in the embodiments can also be implemented in combination when the implementation steps in different embodiments are not conflicted.

[0335] Based on the same principle as the solutions provided in the above embodiments of the present disclosure, an embodiment of the present disclosure further provides a method performed by a second node in a wireless communication system. This method may include steps of:

[0336] receiving a sensing measurement report on a first resource, wherein the first resource is determined based on at least one of first information, a format of a sensing signal, second information, and capability information of the first node, and the first information includes information related to sensing measurement requirements.

[0337] It should be understood that this method is described by using the second node as the executive body, and its principle is the same as the principle of the above method performed by a first node, but the description perspective is different. The contents of various optional embodiments described above by using the first node as the executive body are also applied to the method performed by the second node and will not be repeated here.

[0338] Based on the same principle as the methods provided in the embodiments of the present disclosure, an embodiment of the present disclosure further provides a node.
