[0033] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0034] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0035] Please refer to FIG1 , which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 may include: a terminal device 10 , an access network device 20 , and a core network element 30 .

[0036] The terminal device 10 may refer to a UE (User Equipment), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user apparatus. Optionally, the terminal device 10 may also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5GS (5th Generation System) or a terminal device in a future-evolved PLMN (Public Land Mobile Network), etc., but the embodiments of the present application are not limited thereto. For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art may understand its meaning.

[0037] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal devices 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal devices 10 are collectively referred to as access network equipment. Optionally, communication can be established between terminal devices 10 and core network elements 30 through access network equipment 20. For example, in an LTE (Long Term Evolution) system, access network equipment 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs within EUTRAN. In a 5G NR system, access network equipment 20 may be a Radio Access Network (RAN) or one or more gNBs within the RAN. In the embodiment of the present application, unless otherwise specified, the "network device" refers to the access network device 20, such as a base station.

[0038] The core network element 30 is a network element deployed in the core network. The functions of the core network element 30 are mainly to provide user connection, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network elements in the 5G NR system may include network elements such as the AMF (Access and Mobility Management Function) entity, the UPF (User Plane Function) entity, and the SMF (Session Management Function) entity.

[0039] In some embodiments, the access network device 20 and the core network element 30 communicate with each other via an air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0040] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (e.g., 6G systems (6th Generation Systems, sixth generation mobile communication systems)), as well as other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit this.

[0041] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0042] Synaesthesia refers to the integration of communication and perception, enabling future communication systems to simultaneously perform both functions. While transmitting information over wireless channels, systems proactively learn and analyze channel characteristics to perceive the physical characteristics of the surrounding environment, thereby enhancing these two functions. For example, using base station signals to sense the surrounding environment allows communication links to be designed to avoid obstacles and improve communication performance.

[0043] Next-generation networks (such as 6G networks) are expected to be a fusion of mobile communication networks, perception networks, and computing power networks. In a narrow sense, a perception network refers to a system capable of target positioning (ranging, speed, and angle measurement), target imaging, target detection, target tracking, and target recognition. In a broad sense, a perception network refers to a system that understands the attributes and states of all services, networks, users, and terminals, as well as environmental objects. From the perspective of perception applications, perception can be categorized as follows:

[0044] Outdoor, wide-area or local-area applications: including smart cities (e.g., weather monitoring), smart transportation / high-speed rail (e.g., high-precision map construction, road supervision, intrusion detection), and low-altitude applications (e.g., drone monitoring and obstacle avoidance, flight intrusion detection, flight path management).

[0045] Indoor or local applications: including smart home and health management (such as respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, mobile trajectory tracking, etc.), smart factories (such as intrusion detection, material detection, object defect detection, etc.), etc.

[0046] The above is just an example, providing some classifications of perception applications. The application areas of perception are not limited to the above examples.

[0047] Wireless communication and sensing are two key applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment to enable environmental perception, such as target location, motion recognition, and imaging. Traditionally, sensing and wireless communication exist independently, and this separate design wastes wireless spectrum and hardware resources. Entering the B5G (Beyond 5G) and 6G eras, the communication spectrum is shifting towards millimeter-wave, terahertz, and visible light communications. The spectrum for wireless communication will overlap with the spectrum for traditional sensing. Integrated communication and sensing technology merges wireless communication and sensing functions, leveraging wireless resources for sensing. It can leverage widely deployed cellular networks to achieve sensing services over larger areas. It can leverage base stations and multiple terminals for joint sensing, achieving higher sensing accuracy. It can also reuse wireless communication hardware modules for sensing, reducing costs. In short, integrated communication and sensing technology empowers future wireless communication systems with sensing capabilities, laying the foundation for the development of smart transportation, smart cities, smart factories, drones, and other services.

[0048] "Perception," as used in the embodiments of this application, refers to the process of directly or indirectly obtaining perceptual information about a target or environment based on at least one perceptual signal, such as sound waves, electromagnetic waves, or light waves (including but not limited to lasers). For example, perceptual information about a target or environment may be obtained by sending and receiving perceptual signals and measuring or otherwise processing the perceptual signals, thereby enabling services such as positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0049] In addition, the word "perception" mentioned in the embodiments of the present application can also be replaced by any other word that can express perception-related meanings, such as positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking and target recognition.

[0050] The nodes involved in perception are as follows:

[0051] Perception sending node: the sending node of the perception signal.

[0052] Perception receiving node: a receiving node that perceives signals.

[0053] Perception nodes: Perception sending nodes and perception receiving nodes are collectively referred to as perception nodes, that is, nodes that perform perception.

[0054] Perception Management Node: A node that manages and controls perception tasks. The Perception Management Node assigns perception tasks to the Perception Nodes, which then perform perception and provide feedback to the Perception Management Node after performing the perception task.

[0055] Perception trigger node: a node that initiates perception, sets the configuration of the perception scenario, and parses the perception feedback sent by the perception node.

[0056] Regarding perception, it can be divided into 8 modes as shown in Figure 2.

[0057] Mode 1, base station self-transmitting and self-receiving sensing: The base station transmits a sensing signal and receives an echo signal. In Mode 1, the sensing transmitting node and the sensing receiving node are the same base station. That is, the base station transmits a sensing signal to the sensing target. After the sensing signal is reflected by the sensing target, the same base station receives an echo signal (i.e., the sensing signal after being reflected by the sensing target).

[0058] Mode 2, terminal-based self-transmission and self-reception: The terminal sends a sensing signal and receives an echo signal. In Mode 2, the sensing sending node and the sensing receiving node are the same terminal. That is, the terminal sends a sensing signal to the sensing target, which is then reflected by the sensing target and then received by the same terminal as the echo signal.

[0059] Mode 3, base station cooperative sensing: One base station (base station A in the figure) transmits a sensing signal, and another base station (base station B in the figure) receives the echo signal. In Mode 3, the sensing sending node and the sensing receiving node are different base stations. That is, one base station transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the other base station.

[0060] Mode 4, terminal collaborative sensing: One terminal (such as terminal A in the figure) transmits a sensing signal, and another terminal (such as terminal B in the figure) receives the echo signal. In Mode 4, the sensing sending node and the sensing receiving node are different terminals. That is, one terminal transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the other terminal.

[0061] Mode 5, base station-terminal collaborative sensing: The base station transmits a sensing signal, and the terminal receives an echo signal. In Mode 5, the base station is the sensing transmitting node, and the terminal is the sensing receiving node. Specifically, the base station transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the terminal.

[0062] Mode 6, terminal-base station collaborative sensing: The terminal transmits a sensing signal, and the base station receives an echo signal. In Mode 6, the sensing transmitting node is the terminal, and the sensing receiving node is the base station. Specifically, the terminal transmits a sensing signal to the sensing target, which is then reflected by the sensing target and then received as an echo signal by the base station.

[0063] In Mode 7, the sensing target is the sensing signal sending node. In Mode 7, the sensing sending node is the terminal, and the sensing receiving node is the base station. Because the sensing target (terminal) is the sensing sending node, the sensing signal is sent from the sensing sending node (terminal) to the sensing receiving node (base station) without reflection. The base station can directly receive and interpret the sensing result.

[0064] In Mode 8, the sensing target is the sensing signal receiving node. In Mode 8, the sensing sending node is the base station, and the sensing receiving node is the terminal. Since the sensing target (terminal) is the sensing receiving node, after receiving the sensing signal, the terminal needs to feed back the sensing result to the base station so that the base station can obtain the sensing result.

[0065] The sending node and receiving node of the perception signal can be collectively referred to as the perception node. In the above eight perception modes, there is only one or a pair of perception nodes. In wireless communication systems, the number of terminal devices (such as mobile phones, IoT devices, etc.) is large. When there are multiple perception nodes (i.e., base stations, mobile phones, IoT devices, etc. that send and / or receive perception signals) around a perceived object, the joint participation of multiple perception nodes in perception will improve the accuracy of perception and meet more complex perception service requirements, providing richer perception services. As shown in Figure 3, when there are multiple perception nodes in the system (such as perception node 1, perception node 2, and perception node 3 in Figure 3), there may be a perception control node 31 to control and manage the entire perception service to improve efficiency. The perception control node 31 can be a base station, a terminal device, or a core network element.

[0066] Please refer to FIG4 , which shows a flow chart of a method for configuring a sensing signal provided by an embodiment of the present application. The method may include the following step 410 .

[0067] In step 410, the first node sends configuration information, where the configuration information is used to configure a first parameter. The first parameter includes at least one of the following parameters: a time interval of a perception signal, a number of perception signals, and an interval of a perception signal.

[0068] In some embodiments, the first node is configured to configure the perception signal. The first node sends configuration information, where the configuration information is used to configure a first parameter related to the perception signal. Exemplarily, the configuration information is used to configure the first parameter related to the transmission and / or reception of the perception signal.

[0069] In some embodiments, the first node can be any of the following: an access network device (such as a base station), a terminal device, a server, a core network element, or a perception information collector. In the embodiments of the present application, there is no limitation on the specific device used to implement the first node. For example, for the perception system shown in Figure 3, the first node can be a perception control node.

[0070] In some embodiments, the perception signal may be a specific reference signal, such as a CSI-RS (Channel State Information Reference Signal), a PT-RS (Phase-tracking Reference Signal), a DMRS (Demodulation Reference Signal), an SRS (Sounding Reference Signal), a PRS (Positioning Reference Signal), etc. The perception signal may also be a data signal. In the embodiments of the present application, there is no limitation on the specific type of signal of the perception signal, and this may be determined based on actual conditions without specific requirements.

[0071] In some embodiments, the time interval of the perception signal is used to send and / or receive the perception signal. For example, when the above-mentioned configuration information is configured for a sending node of the perception signal, the time interval of the perception signal may be a sending time interval of the perception signal, which is used to send the perception signal within the time interval. For example, when the above-mentioned configuration information is configured for a receiving node of the perception signal, the time interval of the perception signal may be a receiving time interval of the perception signal, which is used to receive the perception signal within the time interval. For example, when the above-mentioned configuration information is configured for a sending node and a receiving node of the perception signal, or for the self-transmitting and self-receiving perception mode described above, the time interval of the perception signal may include a sending time interval and a receiving time interval of the perception signal, wherein the sending time interval of the perception signal is used to send the perception signal within the time interval, and the receiving time interval of the perception signal is used to receive the perception signal within the time interval. Optionally, the sending time interval of the perception signal and the receiving time interval of the perception signal may be the same or different.

[0072] In some embodiments, when the first parameter includes a time interval for a perception signal, the configuration information may configure one time interval for the perception signal, or may configure multiple time intervals for the perception signal. Exemplarily, the configuration information is used to configure one or more transmission time intervals for the perception signal. Exemplarily, the configuration information is used to configure one or more reception time intervals for the perception signal. Exemplarily, the configuration information is used to configure at least one set of corresponding transmission time intervals and reception time intervals for the perception signal, each set of corresponding transmission time intervals and reception time intervals including one transmission time interval and one reception time interval. Exemplarily, when transmission and reception share the same time interval, the configuration information is used to configure one or more time intervals for the perception signal, and the time intervals are used for transmitting and receiving the perception signal.

[0073] In some embodiments, all or part of the time domain resources within the time interval of the perception signal are used to send and / or receive the perception signal. Exemplarily, all or part of the time domain resources within the time interval of sending the perception signal are used to send the perception signal. Exemplarily, all or part of the time domain resources within the time interval of receiving the perception signal are used to receive the perception signal. Exemplarily, in the case where sending and receiving share the same time interval, all or part of the time domain resources within the time interval of the perception signal are used to send and receive the perception signal. For example, in the case where sending and receiving share the same time interval, the first part of the time domain resources within the time interval of the perception signal is used to send the perception signal, and the second part of the time domain resources is used to receive the perception signal; wherein, the first part of the time domain resources and the second part of the time domain resources may overlap (including full or partial overlap) or may not overlap in the time domain.

[0074] In some embodiments, the time intervals are periodic. For example, as shown in FIG5 , the time intervals are periodic, and there is no time interval between two adjacent time intervals in the time domain. For example, as shown in FIG6 , the time intervals are periodic, and there is a time interval between two adjacent time intervals in the time domain.

[0075] In some embodiments, the time interval is non-periodic. In other words, only one time interval is configured. For example, as shown in FIG7 , the time interval is non-periodic, and only one time interval is configured.

[0076] In some embodiments, whether the time interval is periodic or aperiodic may be specified by the protocol or configured through the above-mentioned configuration information. In some embodiments, if the time interval is periodic, whether there is a time interval between two adjacent time intervals in the time domain, and the length of the time interval, may also be specified by the protocol or configured through the above-mentioned configuration information.

[0077] In some embodiments, the time interval includes one or more time domain units. In some embodiments, the time domain unit is any one of the following: symbol, time slot, frame, sub-frame, millisecond (ms), second (s). The above description of the time domain unit is only exemplary, and the present application does not limit it to other time domain units. In addition, the above symbols can be OFDM (Orthogonal Frequency Division Multiplexing) symbols, FMCW (Frequency Modulated Continuous Wave, frequency modulated continuous wave), OTFS (Orthogonal Time Frequency Space, orthogonal time-frequency space modulation) symbols, etc., and the present application does not limit this.

[0078] In some embodiments, the time interval is determined based on at least two of the following parameters: the starting time domain unit of the time interval, the ending time domain unit of the time interval, and the duration of the time interval. The starting time domain unit of the time interval refers to the first time domain unit occupied by the time interval, that is, the earliest time domain unit in the time domain occupied by the time interval. The ending time domain unit of the time interval refers to the last time domain unit occupied by the time interval, that is, the latest time domain unit in the time domain occupied by the time interval. Exemplarily, the time interval can be determined based on the starting time domain unit and the ending time domain unit of the time interval. Exemplarily, the time interval can also be determined based on the starting time domain unit and the duration of the time interval. Exemplarily, the time interval can also be determined based on the ending time domain unit and the duration of the time interval.

[0079] In some embodiments, the configuration information is also used to configure the time offset of the first perception signal in the time interval. Alternatively, the configuration parameters of the time interval include, in addition to at least two parameters of the starting time domain unit of the time interval, the ending time domain unit of the time interval, and the duration of the time interval, the time offset of the first perception signal. Exemplarily, the time offset of the first perception signal refers to the offset value of the starting time domain unit of the first perception signal sent or received within the time interval relative to the starting time domain unit of the time interval. In some embodiments, if the time offset of the first perception signal is configured, the perception signal can be sent and / or received starting from the position of the time offset of the first perception signal in the time interval; if the time offset of the first perception signal is not configured, the perception signal can be received starting from the starting time domain unit of the time interval, or starting from the time domain unit where the activation signaling is received, or starting from the start time indicated by the activation signaling.

[0080] In some embodiments, the number of perception signals includes: the number of perception signals sent within a time interval, and / or the number of perception signals received within a time interval. For example, for a perception signal sending time interval, the number of perception signals refers to the number of perception signals sent within a sending time interval. For example, for a perception signal receiving time interval, the number of perception signals refers to the number of perception signals received within a receiving time interval. For example, when sending and receiving share the same time interval, the number of perception signals may include the number of perception signals sent within the time interval, and may also include the number of perception signals received within the time interval; the number of perception signals sent and the number of perception signals received may be the same or different. For example, as shown in FIG. 5 , FIG. 6 , or FIG. 7 , the number of perception signals within a time interval is 3.

[0081] In some embodiments, the interval of a perception signal refers to the time interval in the time domain. For example, the interval of a transmitted perception signal refers to the interval between two adjacent transmitted perception signals, such as the interval between the starting time domain units of two adjacent transmitted perception signals. The interval of a perception signal includes: the interval of perception signals transmitted within a time interval, and / or the interval of perception signals received within a time interval. For example, the interval of received perception signals refers to the interval between two adjacent received perception signals, such as the interval between the starting time domain units of two adjacent received perception signals. Exemplarily, for a perception signal transmission time interval, the interval of a perception signal refers to the interval of perception signals transmitted within a transmission time interval. Exemplarily, for a perception signal reception time interval, the interval of a perception signal refers to the interval of perception signals received within a reception time interval. Exemplarily, when transmission and reception share the same time interval, the interval of a perception signal may include the interval of perception signals transmitted within the time interval, and may also include the interval of perception signals received within the time interval; wherein the interval of transmitted perception signals and the interval of received perception signals may be the same or different. Exemplarily, as shown in FIG. 5 , FIG. 6 or FIG. 7 , within a time interval, there is a gap between two adjacent perception signals.

[0082] In some embodiments, the number of perception signals and the interval between perception signals may not be limited to a time interval. Exemplarily, the number of perception signals refers to the number of perception signals sent, or the number of perception signals received. Exemplarily, the interval between perception signals refers to the time interval between two adjacent perception signals sent, or the time interval between two adjacent perception signals received. For example, the second node sends and / or receives perception signals according to the above number and / or interval, starting from the time domain unit in which the configuration information is received, or from the time domain unit in which the activation signaling is received, or from the starting time domain unit indicated by the activation signaling.

[0083] In some embodiments, the interval of sensing the signal may include one or more time domain units. Exemplarily, the time domain unit is any one of the following: symbol, time slot, frame, subframe, millisecond, second, etc.

[0084] In some embodiments, within a time interval of a perception signal, the perception signals may be sent or received at equal intervals throughout the entire interval, or the number of perception signals may be limited so that they are sent or received at equal intervals within a portion of the time interval, with no perception signals being sent or received for the remainder. For example, as shown in FIG5 , FIG6 , or FIG7 , within a time interval, the number of perception signals is three, and the three perception signals are sent or received at equal intervals within a portion of the time interval, with no perception signals being sent or received for the remainder of the time interval.

[0085] In some embodiments, the configuration information is used to configure frequency domain resources for perception signals. The frequency domain resources are used to transmit and / or receive perception signals. For example, when the configuration information is configured for a node transmitting a perception signal, the transmitting node may transmit the perception signal on the frequency domain resources. For example, when the configuration information is configured for a node receiving a perception signal, the receiving node may detect or receive the perception signal on the frequency domain resources.

[0086] In some embodiments, the frequency domain resources include one or more frequency domain units. In some embodiments, the frequency domain unit is any one of the following: subcarrier, RB (Resource Block), sub-band, BWP (Bandwidth Part), RBG (Resource Block Group). The above description of the frequency domain unit is only exemplary, and this application does not limit it to other frequency domain units.

[0087] In some embodiments, the frequency domain resources are indicated by a bitmap or determined based on the frequency domain starting position and the number of included frequency domain units. For example, a bitmap may indicate one frequency domain unit in the frequency domain, or multiple frequency domain units that are continuous or non-continuous in the frequency domain, as the frequency domain resources for the perception signal. For example, a frequency domain unit in the frequency domain, or multiple frequency domain units that are continuous or non-continuous in the frequency domain, may be indicated by the frequency domain starting position and the number of included frequency domain units.

[0088] In some embodiments, the configuration information is used to configure activation signaling for a perception signal. The activation signaling is used to activate the transmission and / or reception of the perception signal. In some embodiments, the activation signaling is used to determine a starting time domain unit for transmitting and / or receiving the perception signal. Exemplarily, the perception signal is transmitted and / or received starting from the time domain unit in which the activation signaling is received. Exemplarily, the perception signal is transmitted and / or received starting from the starting time domain unit indicated by the activation signaling.

[0089] In some embodiments, within a time interval, the perception signals satisfy at least one of the following conditions: the frequency domain resources of the perception signals are the same, the intervals of the frequency domain resources of the perception signals are pre-configured or specified, the frequency domain intervals of the perception signals are the same, the time domain intervals of the perception signals are the same, and the spatial parameters of the perception signals are the same.

[0090] The frequency domain resources of the perception signals can be the same or different within a time interval. The frequency domain resources of the perception signals can be the same or different within different time intervals. When the frequency domain resources of the perception signals are the same, this helps simplify configuration and the content of the configuration information. Furthermore, the frequency domain resources of the perception signals can be configured using the above-mentioned configuration information or specified by the protocol.

[0091] Within a time interval, the frequency domain resources of the sensing signal may or may not have gaps. If within a time interval, the frequency domain resources of the sensing signal have gaps, the gaps may be pre-configured or specified, for example, configured through the above-mentioned configuration information, or specified by a protocol.

[0092] The frequency domain intervals of the sensing signals can be the same or different within a time interval. The frequency domain intervals of the sensing signals can be the same or different within different time intervals. When the frequency domain intervals of the sensing signals are the same, this helps simplify configuration and the content of the configuration information. Furthermore, the frequency domain intervals of the sensing signals can be configured using the aforementioned configuration information or specified by a protocol.

[0093] Within a time interval, the time domain intervals of the sensing signals can be the same or different. Within different time intervals, the time domain intervals of the sensing signals can be the same or different. When the time domain intervals of the sensing signals are the same, this helps simplify configuration and the content of the configuration information. Furthermore, the time domain intervals of the sensing signals can be configured using the above-mentioned configuration information or specified by the protocol.

[0094] The spatial parameters of the perception signals can be the same or different within a time interval. The spatial parameters of the perception signals can be the same or different within different time intervals. These spatial parameters include, but are not limited to, at least one of the following: transmit antenna port, receive antenna port, transmit beam, and receive beam. When the spatial parameters of the perception signals are the same, this simplifies configuration and configuration information. Furthermore, the spatial parameters of the perception signals can be configured using the aforementioned configuration information or specified by the protocol.

[0095] In some embodiments, the first parameter is determined based on a second parameter, where the second parameter includes at least one of the following parameters: sensing accuracy and sensing range. The second parameter reflects the sensing requirements of the sensing service, and different sensing accuracies and / or sensing ranges correspond to different sensing requirements.

[0096] In some embodiments, perception accuracy refers to the accuracy of perception information obtained by processing perception signals. Perception accuracy can be understood as the minimum granularity of the perception result expression, or the minimum interval between multiple perception results, or the minimum value of the perception result. The above-mentioned processing may include measuring the perception signal or other processing methods, which is not limited in this application. Taking the speed of the perception target obtained by measuring the perception signal as an example, the perception accuracy may include the speed perception accuracy for the perception target. Speed ​​perception accuracy can be understood as the minimum granularity of the speed that can be perceived. Exemplarily, the unit of speed perception accuracy can be m / s (meters / second), km / h (kilometers / hour), etc., which is not limited in this application. Exemplarily, the speed perception accuracy can be 0.1m / s, 0.5m / s, 1m / s, 2m / s, 5m / s, 10m / s, etc., which is not limited in this application.

[0097] In some embodiments, a perception interval refers to the interval in which the perception information obtained by processing the perception signal lies. The perception interval can also be understood as a perception range or a perception result range. The above-mentioned processing may include measuring the perception signal or other processing methods, which is not limited in this application. Taking the speed of the perception target obtained by measuring the perception signal as an example, the perception interval may include a speed perception interval for the perception target. The speed perception interval can be understood as the minimum and maximum values ​​of the speed that can be perceived, or the interval range between the above minimum and maximum values. For example, the unit of the speed perception interval can also be m / s (meters per second), km / h (kilometers per hour), etc., which is not limited in this application. For example, the speed perception interval can be [-1m / s, 1m / s), [-2m / s, 2m / s), [-5m / s, 5m / s), [-10m / s, 10m / s), etc., which is not limited in this application. Since speed has a direction, the above-mentioned negative sign can be understood as the direction of speed.

[0098] In some embodiments, the first node determines the first parameter (including at least one parameter of the time interval, number, and interval of the perception signal) based on the second parameter (including at least one parameter of the perception accuracy and the perception interval) and sends configuration information. The configuration information may include the above-mentioned first parameter or any other information that can determine the above-mentioned first parameter. The node that receives the configuration information can then obtain the first parameter based on the configuration information and send and / or receive the perception signal based on the first parameter. In this way, perception measurement that meets the requirements of the above-mentioned perception accuracy and / or perception interval can be achieved.

[0099] In some embodiments, the configuration information is used to configure the second parameter, and the second parameter includes at least one of the following parameters: perception accuracy and perception interval. The description of perception accuracy and perception interval can be found above and will not be repeated here.

[0100] In some embodiments, when the configuration information is used to configure a second parameter and the second parameter includes perceptual accuracy, the configuration information includes a numerical value of the perceptual accuracy, or the configuration information includes an index of the perceptual accuracy. For example, a first mapping relationship may exist between different perceptual accuracies and different indexes. This first mapping relationship may be preconfigured or specified, and the configured perceptual accuracy may be obtained by searching the first mapping relationship based on the perceptual accuracy index included in the configuration information.

[0101] In some embodiments, when the configuration information is used to configure a second parameter and the second parameter includes a perception interval, the configuration information includes a value of the perception interval, or the configuration information includes an index of the perception interval. For example, a second mapping relationship may exist between different perception intervals and different indexes. This second mapping relationship may be preconfigured or specified, and the configured perception interval may be obtained by searching the second mapping relationship based on the index of the perception interval included in the configuration information.

[0102] In some embodiments, the configuration information sent by the first node is used to configure a first parameter (including at least one of the time interval, number, and interval of the perception signal) and a second parameter (including at least one of the perception accuracy and the perception interval). The second node sends and / or receives the perception signal based on the received configuration information. This approach also enables perception measurements that meet the aforementioned perception accuracy and / or perception interval requirements.

[0103] In some embodiments, the perception accuracy and / or perception interval (that is, the second parameter mentioned above) of the perception signal is determined according to business needs, or is indicated by the application layer, or is indicated or configured by other nodes. Among them, different business needs may correspond to different perception accuracy and / or perception intervals. For example, the two different business needs of speed measurement for pedestrians and vehicles have different corresponding perception accuracy and / or perception intervals. In addition, the above method can be executed by the physical layer of the first node, that is, the physical layer determines and sends configuration information. Therefore, whether the physical layer determines the first parameter based on the second parameter, or the configuration information sent by the physical layer is used to configure the first parameter and the second parameter, the second parameter can be indicated to the physical layer by the application layer. Of course, in some other embodiments, the second parameter can also be indicated or configured to the first node by other nodes. The other node can be any node in the perception system other than the first node, such as a server, and this application does not limit this.

[0104] In some embodiments, the first parameter includes parameters that satisfy at least one of the following conditions:

[0105] The time interval of the perceived signal is negatively correlated with the perception accuracy;

[0106] The product of the interval between perception signals and the number of perception signals is negatively correlated with perception accuracy;

[0107] When the interval of perception signals is determined, the number of perception signals is negatively correlated with perception accuracy;

[0108] When the number of perception signals is determined, the interval between perception signals is negatively correlated with perception accuracy;

[0109] The interval of the perceived signal is negatively correlated with the perception interval;

[0110] The time interval of perceiving the signal is negatively correlated with the perceiving interval;

[0111] The product of the interval of the perception signal and the number of the perception signals is negatively correlated with the perception interval;

[0112] When the interval of the perception signal is determined, the number of perception signals is negatively correlated with the perception interval;

[0113] When the number of perception signals is determined, the interval between the perception signals is negatively correlated with the perception interval.

[0114] Among them, A and B are negatively correlated, which means that the larger A is, the smaller B is, and the smaller A is, the larger B is.

[0115] Channel modeling in a channel system includes both large-scale and small-scale channel models. The influencing parameter of the large-scale channel model is the distance between the transmitter and receiver. The main influencing parameters of the small-scale channel model are environmental factors, such as whether there is obstruction, whether it is indoors or outdoors, whether it is on plains, in mountainous areas, or in towns, and whether there is a direct path or multipath. Therefore, the antennas, distance, and relative speed of the transmitter and receiver will affect the channel.

[0116] When perception is used for speed measurement, the channel response can be simplified to Where H(t) refers to the channel response at time t, h′ represents the time-invariant parameter used to calculate the channel response, and λ is the signal wavelength, which can be obtained from the carrier center frequency f c Calculated with the speed of light c, v is the speed and j represents the imaginary unit.

[0117] N channel responses with a time interval of Δt are H(0), H(1), H(2), …, H(N-1). Discrete Fourier Transform (DFT) is performed on these N channel responses to obtain X(k), where Δt is the time interval between two adjacent sensing signal reception / transmissions.

[0118] when When X(k) is the largest, the speed can be calculated.

[0119] It can be seen that the speed perception accuracy is The speed perception range is When N is large enough or infinite, the maximum speed is That is, the speed perception range is

[0120] It can be seen from the above formula that the time interval of the perception signal is negatively correlated with the speed perception accuracy; the product of the interval of the perception signal and the number of perception signals is negatively correlated with the speed perception accuracy; when the interval of the perception signal is determined, the number of perception signals is negatively correlated with the speed perception accuracy; when the number of perception signals is determined, the interval of the perception signal is negatively correlated with the speed perception accuracy; the interval of the perception signal is negatively correlated with the speed perception interval; the time interval of the perception signal is negatively correlated with the speed perception interval; the product of the interval of the perception signal and the number of perception signals is negatively correlated with the speed perception interval; when the interval of the perception signal is determined, the number of perception signals is negatively correlated with the speed perception interval; when the number of perception signals is determined, the interval of the perception signal is negatively correlated with the speed perception interval.

[0126] In some embodiments, the second node can be any of the following: an access network device (such as a base station), a terminal device, a server, a core network element, or a perception information collector. In the embodiments of the present application, there is no limitation on the specific device used to implement the second node.

[0132] In some embodiments, the configuration information is used to configure activation signaling of the perception signal. According to the activation signaling, the second node sends and / or receives the perception signal starting from the time domain unit in which the activation signaling is received, or starting from the starting time domain unit indicated by the activation signaling.

[0133] In some embodiments, the first parameter is specified by the protocol. The second node sends and / or receives the perception signal according to the first parameter specified by the protocol. In some embodiments, at least one parameter of the time interval of the perception signal, the number of perception signals, and the interval of the perception signal is specified by the protocol.

[0136] In some embodiments, the second node sends and / or receives the perception signal according to the first parameter, including: the second node occupies all or part of the time domain resources in the time interval to send and / or receive the perception signal.

[0137] In addition, for details not described in detail in this embodiment, please refer to the relevant introduction and description in the embodiment of the configuration method above.

[0138] The technical solution provided in the embodiment of the present application specifies at least one parameter of the time interval, number, and interval of the perception signal through configuration or protocol, and the nodes in the perception system send and / or receive perception signals according to the above parameters, which can meet different perception needs.

[0139] Below, the configuration and transmission method of the perception signal provided by this application is described using an example in which a first node sends configuration information and a second node sends and / or receives a perception signal based on the configuration information. As shown in Figure 9, the method may include the following steps:

[0140] Step 910: The first node sends configuration information.

[0141] Step 920: The second node sends and / or receives a perception signal according to the configuration information.

[0142] In some embodiments, the configuration information is used to configure a first parameter, where the first parameter includes at least one of the following parameters: a time interval of a perception signal, a number of perception signals, and an interval between perception signals. In some embodiments, the configuration information is also used to configure frequency domain resources for the perception signal. In some embodiments, the configuration information is also used to configure activation signaling for the perception signal.

[0143] In some embodiments, the first node determines the first parameter based on a second parameter, where the second parameter includes at least one of the following parameters: sensing accuracy and sensing interval. Exemplarily, the first node determines at least one of the following parameters: a time interval of a sensing signal, a number of sensing signals, or an interval between sensing signals based on at least one of the sensing accuracy and sensing interval. After determining the first parameter based on the second parameter, the first node may send the determined first parameter to the second node via configuration information, so that the second node sends and / or receives sensing signals based on the configuration information.

[0144] In some embodiments, the configuration information is used to configure the time interval of the perception signal, the number of perception signals, the interval of the perception signal, and the frequency domain resources of the perception signal. For example, the configuration information indicates that N consecutive perception signals with a time interval of T are sent and / or received on the frequency domain resources configured in one or more time intervals. The one or more time intervals may be periodic or signaling-triggered.

[0145] Taking the perception application scenario of speed measurement as an example, assuming that the walking speed is approximately 1.5m / s (meters / second), there are a first node and a second node in the perception system. The first node is configured with a perception signal, and the second node sends and / or receives a perception signal. The perception signal is used to measure the moving speed of the perception target (person).

[0146] Assume f c =2GHz, if you want to measure the speed of a person walking, you can determine the corresponding sensing signal configuration information based on the speed range of 1.5m / s. It can be calculated that Δt = 0.05s, that is, when configuring the perception signal, the interval of the perception signal is configured as T = 0.05s, so that the perception target moving speed in the interval of [-1.5m / s, 1.5m / s) can be detected.

[0147] Assume f c =2GHz, if the required speed perception accuracy is 0.1m / s, then according to the speed perception accuracy It can be calculated that N = 15. When configuring the sensing signal, the number of sensing signals with an interval of T = 0.05s is at least N = 15, which can meet the requirement of a speed sensing accuracy of 0.1m / s.

[0148] If speed measurement is required every time interval L, a periodic transmission time interval needs to be configured for the sensing signal, and at least N sensing signals with an interval of T are continuously sent on the frequency domain resources configured in each time interval L. Correspondingly, the first node sends activation signaling to start the periodic time interval L.

[0149] In some embodiments, the configuration information is used to configure a first parameter and a second parameter; the first parameter includes at least one of the following: a time interval of a perception signal, the number of perception signals, and an interval of perception signals; the second parameter includes at least one of the following: perception accuracy and a perception interval. In some embodiments, the configuration information is also used to configure frequency domain resources for the perception signal. In some embodiments, the configuration information is also used to configure activation signaling for the perception signal.

[0155] For example, the configuration information is used to configure the time interval L of the perception signal and the interval T of the perception signal within the time interval L. Starting from the start time of the time interval L on the configured frequency domain resources, or starting from the position of the transmission time offset O of the first perception signal in the time interval L, or starting from the activation signaling, or starting from the start time indicated by the activation signaling, the perception signal is sent once every interval T, and floor(L / T)+1 perception signals are sent, where floor means rounding down.

[0156] According to this configuration, the perception signal sent / received can achieve a speed perception accuracy of Speed ​​perception range is speed perception.

[0157] Example 3: The configuration information is used to configure the time interval, number, interval, and frequency domain resources of the sensing signal. Optionally, the configuration information is also used to configure an activation instruction.

[0158] For example, the configuration information is used to configure the time interval L of the perception signal, the interval T of the perception signal within the time interval L, and the number of continuously transmitted perception signals. Starting from the start time of the time interval L, or from the position of the transmission time offset O of the first perception signal in the time interval L, or from the activation signaling, or from the start time indicated by the activation signaling, the perception signal is transmitted once every interval T on the configured frequency domain resources, for a total of N perception signals, where N ≤ floor(L / T)+1, where floor indicates rounding down. This implicitly indicates that the perception signals are transmitted at equal intervals within the entire or partial range of the time interval T.

[0159] According to this configuration, the perception signal sent / received can achieve a speed perception accuracy of Speed ​​perception range is speed perception.

[0160] Example 4: The configuration information is used to configure the number, interval, and frequency domain resources of the sensing signals. Optionally, the configuration information is also used to configure an activation instruction.

Starting from the access time, or the activation signaling, or the start time indicated by the activation signaling, the perception signal is sent once every T interval on the configured frequency domain resources, and a total of N perception signals are sent.

[0163] Example 5: The configuration information is used to configure the number of sensing signals, sensing accuracy, and frequency domain resources. Optionally, the configuration information is also used to configure an activation instruction.

[0164] For example, the configuration information is used to configure the number of perception signals N and the speed perception accuracy X, starting from the access time, or the activation signaling, or the start time indicated by the activation signaling on the configured frequency domain resources, and every interval A perception signal is sent once, and a total of N perception signals are sent.

[0165] According to this configuration, the sent / received perception signal can achieve a speed perception accuracy of X and a speed perception range of speed perception.

[0166] Example 6: The configuration information is used to configure the number of sensing signals, sensing intervals, and frequency domain resources. Optionally, the configuration information is also used to configure an activation instruction.

[0167] For example, the configuration information is used to configure the number of perception signals N and the speed perception interval [V_min, V_max), starting from the access time, or the activation signaling start, or the start time indicated by the activation signaling, on the configured frequency domain resources, and every interval A perception signal is sent once, and a total of N perception signals are sent.

[0168] The perception signals sent / received according to this configuration can achieve speed perception with a speed perception accuracy of V_max / (N-1) and a speed perception interval of [V_min, V_max).

[0169] Example 7: The configuration information is used to configure the interval, perception accuracy, and frequency domain resources of the sensing signal. Optionally, the configuration information is also used to configure an activation instruction.

[0170] For example, the configuration information is used to configure the interval T of the perception signal and the speed perception accuracy X. Starting from the access time, or the activation signaling, or the start time indicated by the activation signaling, the perception signal is sent once every T interval on the configured frequency domain resource.
