[0030] For the purpose of making the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0031] The network architecture and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical scheme of the embodiments of the present application, and do not constitute a limitation on the technical scheme provided by the embodiments of the present application. It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new service scenarios, the technical scheme provided by the embodiments of the present application is also applicable to similar technical problems.

[0032] Please refer to FIG. 1, which shows a schematic diagram of a network architecture 100 according to an embodiment of the present application. The network architecture 100 can include: a terminal device 10, an access network device 20 and a core network element 30.

[0033] The terminal device 10 can refer to a UE (User Equipment), an access terminal, a user unit, a user 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. Alternatively, the terminal device 10 can 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 function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted 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., and the embodiments of the present application are not limited thereto. For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in the cell managed by each access network device 20. The terminal device can also be referred to as a terminal or a UE, and those skilled in the art can understand its meaning.

[0034] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the name of the "access network device" may change. For ease of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. Optionally, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network element 30. Illustratively, in the LTE (Long Term Evolution) system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in the 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN. In the embodiments of the present application, the "network device" refers to the access network device 20, such as a base station, unless otherwise specified.

[0035] The core network element 30 is a network element deployed in the core network, and the main functions of the core network element 30 are to provide user connection, manage users, and complete bearer for services, and provide an interface to external networks as a bearer network. For example, the core network element in the 5G NR system can include an AMF (Access and Mobility Management Function) entity, a UPF (User Plane Function) entity, and an SMF (Session Management Function) entity.

[0036] In some embodiments, the access network device 20 and the core network element 30 communicate with each other through a certain 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 through a certain air interface technology, such as the Uu interface.

[0037] The "5G NR system" in this application embodiment can 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 this application embodiment can be applied to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (such as 6G systems (6th Generation System)). They can also be applied to other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, and this application does not limit them in this regard.

[0038] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0039] Integrated communication and sensing refers to the fusion of communication and sensing functions, enabling future communication systems to simultaneously possess both communication and sensing capabilities. While transmitting information over a wireless channel, the system actively recognizes and analyzes the channel's characteristics to perceive the physical features of the surrounding environment, thus enhancing both communication and sensing functions. For example, by using base station signals to sense information about the surrounding environment and designing communication links, obstacles can be avoided, improving communication performance.

[0040] Next-generation networks (such as 6G networks) are expected to be a fusion of mobile communication networks, sensing networks, and computing networks. In a narrow sense, a sensing network refers to a system with capabilities such as target localization (range measurement, velocity measurement, angle measurement), target imaging, target detection, target tracking, and target recognition. In a broad sense, a sensing network refers to a system that possesses the attributes and states of all services, networks, users, terminals, and environmental objects. From the perspective of sensing applications, sensing can be categorized as follows:

[0041] Outdoor, wide-area, or local applications include smart cities (e.g., weather monitoring), smart transportation / high-speed rail (e.g., high-precision map building, road monitoring, intrusion detection), and low-altitude applications (e.g., drone monitoring and obstacle avoidance, flight intrusion detection, flight path management).

[0042] Indoor or local area applications: including smart home and health management (e.g. respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, mobile trajectory tracking, etc.), smart factory (e.g. intrusion detection, material detection, article defect detection, etc.), etc.

[0043] The above is only exemplary, and provides a classification of some sensing applications, and the application area of sensing is not limited to the above examples.

[0044] Wireless communication and sensing are two important applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment to achieve environmental sensing such as target positioning, action recognition, imaging, etc. Traditional sensing and wireless communication exist independently, and the separate design wastes wireless spectrum and hardware resources. In the B5G (Beyound 5G) and 6G era, the communication spectrum moves to millimeter wave, terahertz, and visible light communication. In the future, the spectrum of wireless communication will coincide with the traditional sensing spectrum. Communication and sensing integration technology integrates wireless communication and sensing functions, which can use wireless communication resources to achieve sensing functions; can use widely deployed cellular networks to implement sensing services in a larger area; can use base stations and multiple terminals for joint sensing to achieve higher sensing accuracy; and can reuse wireless communication hardware modules to implement sensing functions and reduce costs. In summary, communication and sensing integration technology enables future wireless communication systems to have sensing capabilities, providing a foundation for the development of future smart transportation, smart cities, smart factories, and unmanned aerial vehicles.

[0045] The "sensing" mentioned in the embodiments of the present application refers to a process of directly or indirectly obtaining sensing information of a target or an environment based on at least one sensing signal such as a sound wave, an electromagnetic wave, or a light wave (including but not limited to a laser). For example, by sending and receiving a sensing signal and measuring or otherwise processing the sensing signal, sensing information of a sensing target or an environment is obtained, such as implementing positioning, distance measurement, speed measurement, angle measurement, target imaging, target detection, target tracking, target recognition, etc.

[0046] In addition, the "sensing" mentioned in the embodiments of the present application can also be replaced by any other word that can represent the meaning of sensing, such as positioning, distance measurement, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition, etc.

[0047] The nodes participating in sensing include the following:

[0048] Sensing transmitting node: a node for transmitting a sensing signal.

[0049] Sensing receiving node: a node for receiving a sensing signal.

[0050] Sensing node: the sensing transmitting node and the sensing receiving node are collectively referred to as a sensing node, i.e., a node for performing sensing.

[0051] Sensing management node: a node for managing and controlling a sensing task. The sensing management node configures a sensing task to the sensing node, and the sensing node feeds back a sensing result to the sensing management node after performing sensing. The sensing management node can also be referred to as a sensing control node or other names, which are not limited in the present application.

[0052] Sensing trigger node: a node for initiating sensing, setting a configuration of a sensing scene, and analyzing a sensing feedback sent by a sensing node.

[0053] For sensing, there are 8 modes as shown in FIG. 2.

[0054] Mode 1, base station self-sensing and self-receiving: a base station transmits a sensing signal and receives a backwave 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 a sensing target, and the base station receives a backwave signal (i.e., the sensing signal reflected by the sensing target) after the sensing signal is reflected by the sensing target.

[0055] Mode 2, terminal self-sensing and self-receiving: a terminal transmits a sensing signal and receives a backwave signal. In mode 2, the sensing transmitting node and the sensing receiving node are the same terminal. That is, the terminal transmits a sensing signal to a sensing target, and the terminal receives a backwave signal after the sensing signal is reflected by the sensing target.

[0056] Mode 3, base station cooperative sensing: one base station (such as base station A in the figure) transmits a sensing signal, and another base station (such as base station B in the figure) receives a backwave signal. In mode 3, the sensing transmitting node and the sensing receiving node are different base stations. That is, one base station transmits a sensing signal to a sensing target, and another base station receives a backwave signal after the sensing signal is reflected by the sensing target.

[0057] Mode 4, terminal cooperative 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 a backwave signal. In mode 4, the sensing transmitting node and the sensing receiving node are different terminals. That is, one terminal transmits a sensing signal to a sensing target, and another terminal receives a backwave signal after the sensing signal is reflected by the sensing target.

[0058] Mode 5, base station-terminal cooperative sensing: a base station transmits a sensing signal, and a terminal receives a backwave signal. In mode 5, the sensing transmitting node is a base station, and the sensing receiving node is a terminal. That is, the base station transmits a sensing signal to a sensing target, and the terminal receives a backwave signal after the sensing signal is reflected by the sensing target.

[0059] Mode 6, terminal-base station cooperative sensing: the terminal sends the sensing signal, and the base station receives the echo signal. In mode 6, the sensing sending node is the terminal, and the sensing receiving node is the base station. That is, the terminal sends the sensing signal to the sensing target, and the base station receives the echo signal after the sensing signal is reflected by the sensing target.

[0060] 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. Since the sensing target (terminal) is the sensing sending node, the sensing signal sent by the sensing sending node (terminal) to the sensing receiving node (base station) does not need to be reflected and can be directly analyzed by the base station after being received.

[0061] 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, the terminal needs to feed back the sensing result to the base station after receiving the sensing signal, so that the base station knows the sensing result.

[0062] The sending node of the sensing signal and the receiving node of the sensing signal can be collectively referred to as a sensing node. In the above eight sensing modes, there is only one or a pair of sensing nodes, and in a wireless communication system, the number of terminal devices (such as mobile phones, IoT devices, etc.) is large. When there are multiple sensing nodes (i.e., base stations, mobile phones, IoT devices, etc. that can send and / or receive sensing signals) around a sensed object, multiple sensing nodes jointly participating in sensing can improve the accuracy of sensing and meet more complex sensing service requirements to provide more abundant sensing services. As shown in FIG. 3, when there are multiple sensing nodes (such as sensing node 1, sensing node 2, and sensing node 3 in FIG. 3) in the system, there can be a sensing control node 31 to control and manage the entire sensing service to improve efficiency. The sensing control node 31 can be a base station, a terminal device, or a core network element.

[0063] Random phase refers to a phase update introduced due to a change (for example, turning on, turning off, adjusting parameters, etc.) in the state of at least one of a transmitter antenna, a radio frequency module (including various devices connected to a radio frequency channel), a digital processing module, and a clock module during signal sending and receiving.

[0064] If a device has more than one transmitter, each transmitter can generate an independent random phase. The random phase is generally consistent within the transmission signal bandwidth, but the random phase values generated at different times are different and randomly distributed within a certain radian range. The time-domain random phase can seriously affect the measurement of Doppler or speed, and even usually cause the Doppler or speed to be unable to be measured.

[0065] Phase-based ranging refers to measuring the phase of a received signal and comparing or operating with the phase of a transmitted signal to achieve ranging.

[0066] Phase-based velocity measurement refers to that the change of the phase of a received signal is caused by the change of the distance R of an object, and thus the phase change of the received signal in a period of time t is observed to estimate the Doppler or velocity through R / t.

[0067] Random phase generally has no rule and is difficult to estimate. However, the existence of random phase will cause errors in phase-based ranging and velocity measurement. Therefore, random phase elimination technology is crucial for phase-based sensing technology.

[0068] Please refer to FIG. 4, which shows a flowchart of a configuration method according to an embodiment of the present application. The method can be applied to the scenarios or architectures shown in FIGS. 1 to 3. The method can include the following step 410.

[0069] In step 410, a first node transmits configuration information, which is used to indicate the consistency relationship of a plurality of antenna ports of a sensing transmitting node.

[0070] In some embodiments, the first node is a sensing transmitting node, which refers to a node that transmits a sensing signal.

[0071] In some embodiments, the first node is a sensing management node, which refers to a node that manages and controls a sensing task.

[0072] In some embodiments, the first node can be a core network element, a network device or a terminal device.

[0073] In some embodiments, the first node transmits the configuration information in a broadcast manner, and the first node broadcasts the configuration information.

[0074] In some embodiments, the first node transmits the configuration information to a second node.

[0075] In some embodiments, the second node receives the configuration information. For example, the second node receives the configuration information broadcast by the first node, or the second node receives the configuration information transmitted by the first node to the second node.

[0076] In some embodiments, the second node is a sensing receiving node, which refers to a node that receives a sensing signal.

[0077] In some embodiments, the second node can be a network device or a terminal device.

[0078] In some embodiments, an antenna port refers to an interface between an antenna and a radio frequency front end for transmitting radio frequency signals. An antenna port is related to a physical layer. An antenna port is a logical concept, not a physical concept like a radio frequency antenna. Each antenna port represents a specific and unique channel model. One antenna port can be mapped to a single physical antenna or multiple physical antennas.

[0079] In some embodiments, an antenna channel refers to a transmission path of a signal from a baseband to a transmitting antenna or a receiving antenna, including the processing of the signal in an antenna system.

[0080] In some embodiments, there is a certain mapping relationship between an antenna port and an antenna channel.

[0081] In some embodiments, the mapping relationship between an antenna port and an antenna channel can be understood through physical connections. In a wireless communication system, an antenna port is one-to-one with an antenna channel, or an antenna port is one-to-many with an antenna channel. Each antenna port corresponds to one or more antenna channels, and signals are transmitted and received through each channel. Therefore, the "antenna port" mentioned in this application can also be replaced by "antenna channel".

[0082] Secondly, from the perspective of signal processing, the mapping relationship between the antenna port and the antenna channel is also reflected in the scheduling and allocation of signals. In a multi-antenna system, the selection and scheduling of antenna ports will affect the transmission and reception of signals. Different antenna ports correspond to different antenna channels, and through reasonable scheduling, signal isolation and resource allocation between multiple users can be achieved.

[0083] In addition, the mapping relationship between the antenna port and the antenna channel also involves the design and deployment of the antenna array. In a large-scale antenna system, the mapping relationship between the antenna port and the antenna channel needs to consider the structure and layout of the antenna array to achieve effective control and management of signals.

[0084] In some embodiments, the multiple antenna ports of the sensing transmitting node refer to the multiple transmitting antenna ports of the sensing transmitting node, i.e., the sensing transmitting node has multiple transmitting antenna ports for transmitting sensing signals. In the embodiments of the present application, unless otherwise specified, the antenna port refers to the transmitting antenna port.

[0085] In some embodiments, the consistency relationship comprises at least one of: whether the consistency exists; and at least one group of antenna ports having the consistency. The consistency can exist or not exist. In addition, each group of antenna ports having the consistency comprises at least two antenna ports. For example, antenna port 1 and antenna port 2 have the consistency, and the two antenna ports can be regarded as a group of antenna ports having the consistency. For example, antenna port 1, antenna port 2, and antenna port 3 have the consistency, and the three antenna ports can be regarded as a group of antenna ports having the consistency.

[0086] In some embodiments, the configuration information is used to indicate whether the plurality of antenna ports of the sensing sending node has the consistency, which means that the configuration information is used to indicate that all the antenna ports of the sensing sending node have the consistency, or is used to indicate that all the antenna ports of the sensing sending node do not have the consistency. All the antenna ports having the consistency means that any two antenna ports of the plurality of antenna ports of the sensing sending node have the consistency. All the antenna ports not having the consistency means that any two antenna ports of the plurality of antenna ports of the sensing sending node do not have the consistency.

[0087] For example, the sensing sending node has two antenna ports, including antenna port 1 and antenna port 2. If antenna port 1 and antenna port 2 have the consistency, the configuration information is used to indicate that the two antenna ports of the sensing sending node have the consistency. If antenna port 1 and antenna port 2 do not have the consistency, the configuration information is used to indicate that the two antenna ports of the sensing sending node do not have the consistency.

[0088] For example, the sensing sending node has three antenna ports, including antenna port 1, antenna port 2, and antenna port 3. If any two antenna ports of the three antenna ports have the consistency, i.e., antenna port 1, antenna port 2, and antenna port 3 have the consistency, the configuration information is used to indicate that the three antenna ports of the sensing sending node have the consistency. If there are at least two antenna ports of the three antenna ports that do not have the consistency, such as antenna port 1 and antenna port 2 have the consistency, but antenna port 1 and antenna port 3 do not have the consistency, the configuration information is used to indicate that the three antenna ports of the sensing sending node do not have the consistency. If any two antenna ports of the three antenna ports do not have the consistency, i.e., antenna port 1 and antenna port 2 do not have the consistency, antenna port 1 and antenna port 3 do not have the consistency, and antenna port 2 and antenna port 3 also do not have the consistency, the configuration information is also used to indicate that the three antenna ports of the sensing sending node do not have the consistency.

[0089] In some embodiments, the configuration information is used to indicate whether the multiple antenna ports of the sensing transmitting node have coherence, which means that the configuration information is used to indicate that there is at least one group of antenna ports having coherence among all the antenna ports of the sensing transmitting node, or used to indicate that there is no any group of antenna ports having coherence among all the antenna ports of the sensing transmitting node.

[0090] For example, the sensing transmitting node has three antenna ports, including antenna port 1, antenna port 2 and antenna port 3. If any two of the three antenna ports have coherence, i.e., antenna port 1, antenna port 2 and antenna port 3 have coherence, the configuration information is used to indicate that there is at least one group of antenna ports having coherence among all the antenna ports of the sensing transmitting node. If there are at least two antenna ports having coherence among the three antenna ports, such as antenna port 1 and antenna port 2 have coherence, but antenna port 1 and antenna port 3 do not have coherence, the configuration information is also used to indicate that there is at least one group of antenna ports having coherence among all the antenna ports of the sensing transmitting node. If any two of the three antenna ports do not have coherence, i.e., antenna port 1 and antenna port 2 do not have coherence, antenna port 1 and antenna port 3 do not have coherence, and antenna port 2 and antenna port 3 do not have coherence, the configuration information is used to indicate that there is no any group of antenna ports having coherence among all the antenna ports of the sensing transmitting node.

[0091] In some embodiments, the configuration information is used to indicate that there is at least one group of antenna ports having coherence among the multiple antenna ports of the sensing transmitting node, and each group of antenna ports having coherence includes at least two antenna ports.

[0092] For example, the sensing transmitting node has three antenna ports, including antenna port 1, antenna port 2 and antenna port 3. If any two of the three antenna ports have coherence, i.e., antenna port 1, antenna port 2 and antenna port 3 have coherence, the configuration information is used to indicate that there is one group of antenna ports having coherence among the multiple antenna ports of the sensing transmitting node, i.e., {antenna port 1, antenna port 2, antenna port 3}; or the configuration information is used to indicate that there are three groups of antenna ports having coherence among the multiple antenna ports of the sensing transmitting node, i.e., {antenna port 1, antenna port 2}, {antenna port 1, antenna port 3}, {antenna port 2, antenna port 3}.

[0093] Exemplarily, the sensing transmitting node has 3 antenna ports, including antenna port 1, antenna port 2 and antenna port 3. If antenna port 1 and antenna port 2 have consistency, but antenna port 1 and antenna port 3 do not have consistency, the configuration information is used to indicate that, in the multiple antenna ports of the sensing transmitting node, a group of antenna ports having consistency, i.e., {antenna port 1, antenna port 2}.

[0094] Exemplarily, the sensing transmitting node has 4 antenna ports, including antenna port 1, antenna port 2, antenna port 3 and antenna port 4. If antenna port 1 and antenna port 2 have consistency, antenna port 3 and antenna port 4 have consistency, but antenna port 1 and antenna port 3 or 4 do not have consistency, and antenna port 2 and antenna port 3 or 4 do not have consistency, the configuration information is used to indicate that, in the multiple antenna ports of the sensing transmitting node, 2 groups of antenna ports having consistency, i.e., {antenna port 1, antenna port 2}, {antenna port 3, antenna port 4}.

[0095] Through the above method, the configuration information sent by the first node can indicate whether the multiple antenna ports of the sensing transmitting node have consistency, and / or at least one group of antenna ports having consistency, so that the receiving end can utilize the consistency of the multiple antenna ports for signal processing.

[0096] In some embodiments, the configuration information includes at least one of the following: first information, second information; wherein the first information is used to indicate the number of antenna ports of the sensing transmitting node, and the second information is used to indicate the consistency relationship of the multiple antenna ports of the sensing transmitting node.

[0097] In some embodiments, the first information used to indicate the number of antenna ports of the sensing transmitting node refers to the first information used to indicate the number of transmitting antenna ports of the sensing transmitting node. The second information used to indicate the consistency relationship of the multiple antenna ports of the sensing transmitting node refers to the second information used to indicate the consistency relationship of the multiple transmitting antenna ports of the sensing transmitting node. The consistency relationship of the multiple transmitting antenna ports includes at least one of the following: whether having consistency; at least one group of antenna ports having consistency. For specific descriptions, refer to the above embodiments.

[0098] In some embodiments, the second information is used to indicate the consistency relationship of the multiple antenna ports of the sensing transmitting node, including: the second information is used to indicate that all the antenna ports of the sensing transmitting node have consistency; or, the second information is used to indicate that all the antenna ports of the sensing transmitting node do not have consistency. Illustratively, when the second information is a first value, it is used to indicate that all the antenna ports of the sensing transmitting node have consistency; when the second information is a second value, it is used to indicate that all the antenna ports of the sensing transmitting node do not have consistency; wherein the first value and the second value are different. For example, the first value is "yes", and the second value is "no". Alternatively, the second information can be represented by 1 bit, the first value is "1", and the second value is "0"; or, the first value is "0", and the second value is "1".

[0099] In some embodiments, the second information is used to indicate the consistency relationship of the multiple antenna ports of the sensing transmitting node, including: the second information is used to indicate that, among all the antenna ports of the sensing transmitting node, there is at least one group of antenna ports having consistency; or, the second information is used to indicate that, among all the antenna ports of the sensing transmitting node, there is no any group of antenna ports having consistency.

For example, the first value is "yes", and the second value is "no". Alternatively, the second information can be represented by 1 bit, the first value is "1", and the second value is "0"; or, the first value is "0", and the second value is "1".

[0100] In some embodiments, the second information is used to indicate the consistency relationship of the multiple antenna ports of the sensing transmitting node, including: the second information is used to indicate at least one group of antenna ports of the sensing transmitting node having consistency. Wherein, the antenna ports can be represented by numbers, and different antenna ports can be distinguished by different numbers. The above numbers can also be called indexes, identifications or other names, which are not limited in the present application. The numbers of the antenna ports can be configured by the sensing transmitting node, or configured by the first node, or determined according to a pre-defined default rule, which are not limited in the present application.

[0101] In some embodiments, the second information includes at least one group of antenna port numbers, and each group of antenna port numbers includes at least two numbers of antenna ports having consistency.

[0102] Exemplarily, the sensing transmitting node has 3 antenna ports, including antenna port 1, antenna port 2 and antenna port 3, and the numbers of the 3 antenna ports are assumed to be 1, 2 and 3 respectively. If any two of the 3 antenna ports have consistency, i.e., antenna port 1, antenna port 2 and antenna port 3 have consistency, the configuration information includes first information and second information, the first information is used to indicate that the number of antenna ports of the sensing transmitting node is 3, and the second information is used to indicate that, among the 3 antenna ports of the sensing transmitting node, a group of antenna ports having consistency is {antenna port 1, antenna port 2, antenna port 3}, and the second information can include the numbers {1, 2, 3} of the group of antenna ports.

[0103] Exemplarily, the sensing transmitting node has 3 antenna ports, including antenna port 1, antenna port 2 and antenna port 3, and the numbers of the 3 antenna ports are assumed to be 1, 2 and 3 respectively. If antenna port 1 and antenna port 2 have consistency, but antenna port 1 and antenna port 3 do not have consistency, the configuration information includes first information and second information, the first information is used to indicate that the number of antenna ports of the sensing transmitting node is 3, and the second information is used to indicate that, among the 3 antenna ports of the sensing transmitting node, a group of antenna ports having consistency is {antenna port 1, antenna port 2}, and the second information can include the numbers {1, 2} of the group of antenna ports.

[0104] Exemplarily, the sensing transmitting node has 4 antenna ports, including antenna port 1, antenna port 2, antenna port 3 and antenna port 4, and the numbers of the 4 antenna ports are assumed to be 1, 2, 3 and 4 respectively. If antenna port 1 and antenna port 2 have consistency, antenna port 3 and antenna port 4 have consistency, but antenna port 1 and antenna port 3 or 4 do not have consistency, and antenna port 2 and antenna port 3 or 4 do not have consistency, the configuration information includes first information and second information, the first information is used to indicate that the number of antenna ports of the sensing transmitting node is 4, and the second information is used to indicate that, among the 4 antenna ports of the sensing transmitting node, 2 groups of antenna ports having consistency are {antenna port 1, antenna port 2} and {antenna port 3, antenna port 4}, and the second information can include the numbers {1, 2} and {3, 4} of the 2 groups of antenna ports.

[0105] In the above manner, the second information can explicitly indicate the consistency relationship of the multiple antenna ports of the sensing transmitting node.

[0106] In some embodiments, the second information can also implicitly indicate the coherence relationship of the multiple antenna ports of the perception sending node by using other parameters or information. For example, by using an antenna panel indication, the antenna ports belonging to the same antenna panel / TRP (Transmission Reception Point) have coherence, and the antenna ports not belonging to the same panel / TRP do not have coherence.

[0107] In some embodiments, the n antenna ports have coherence, including: when the baseband signals of the n antenna ports are the same, the amplitudes of the transmission signals of the n antenna ports have coherence, and / or the phases of the transmission signals of the n antenna ports have coherence, n being an integer greater than 1.

[0108] If the baseband signals of the n antenna ports are different, the baseband signals can be eliminated at the receiving end, which is equivalent to the baseband signals of the n antenna ports being the same, and the random phase can still be eliminated by using the coherence of the n antenna ports.

[0109] It can be understood that the essence of coherence is that the influence of the radio frequency channel on the signal is the same, or the difference is less than a threshold value. The coherence of the antenna ports includes amplitude coherence and / or phase coherence, and the coherence of the antenna ports can be due to the fact that the antenna ports corresponding to the same radio frequency channel naturally have coherence, i.e., the difference in the signals is less than a threshold value. It can also be obtained by using a calibration algorithm or a calibration network that meets certain accuracy requirements.

[0110] In some embodiments, the amplitudes of the transmission signals of the n antenna ports have coherence, including: the amplitude difference of the transmission signals of the n antenna ports is less than a first threshold value; and / or the phases of the transmission signals of the n antenna ports have coherence, including: the phase difference of the transmission signals of the n antenna ports is less than a second threshold value. The first threshold value and / or the second threshold value can be agreed upon by a protocol or preconfigured, which is not limited in the present application.

[0111] In some embodiments, the configuration information further includes third information, the third information being used to indicate the amplitude and / or phase difference of the transmission signals between the antenna ports having coherence. For example, the amplitude and / or phase difference can be whether it is less than a threshold value, or can be a difference level (or a difference level), or can be a specific difference value. The threshold value can be agreed upon by a protocol or preconfigured, which is not limited in the present application. In addition, each difference level corresponds to a range of difference values. Taking the phase difference as an example, difference level 1 represents that the phase difference is between 0-0.01π, difference level 2 represents that the phase difference is between 0.01π-0.05π, and difference level 3 represents that the phase difference is greater than 0.05π.

[0112] By the above manner, the amplitude and / or phase difference of the signals transmitted between the antenna ports with consistency is indicated in the configuration information, so that the receiving end can utilize the consistency of the multiple antenna ports and the difference to perform signal processing, which helps to improve the accuracy of the perception result.

[0113] Considering the amplitude and / or phase of the signals transmitted by different antenna ports, there is generally no absolute same. In some embodiments, in addition to the information for indicating whether there is consistency, the configuration information can further include fourth information for indicating a consistency parameter of the antenna ports. The consistency parameter can be understood as a relevant parameter for distinguishing whether the antenna ports have consistency.

[0114] For example, the consistency parameter includes an amplitude consistency parameter and / or a phase consistency parameter. The amplitude consistency parameter is used to distinguish whether the antenna ports have consistency from the perspective of the amplitude of the signals transmitted by the antenna ports. For example, the amplitude consistency parameter includes a first amplitude value. If the amplitude difference of the signals transmitted by any two antenna ports is less than the first amplitude value, it is determined that the two antenna ports have consistency. If the amplitude difference of the signals transmitted by any two antenna ports is greater than the first amplitude value, it is determined that the two antenna ports do not have consistency. The phase consistency parameter is used to distinguish whether the antenna ports have consistency from the perspective of the phase of the signals transmitted by the antenna ports. For example, the phase consistency parameter includes a first phase value. If the phase difference of the signals transmitted by any two antenna ports is less than the first phase value, it is determined that the two antenna ports have consistency. If the phase difference of the signals transmitted by any two antenna ports is greater than the first phase value, it is determined that the two antenna ports do not have consistency. Exemplarily, the unit of the first amplitude value can be dB, and the unit of the first phase value can be degrees.

[0115] By including the fourth information for indicating the consistency parameter of the antenna ports in the configuration information, the receiving or processing node of the perception signal can help to judge the accuracy of the perception result.

[0116] In some embodiments, as shown in FIG. 5, the method further includes the following steps:

[0117] In step 420, the second node obtains the perception result based on the consistency relationship between the antenna ports.

[0118] In step 430, the second node transmits the perception result information. The perception result information includes one of the following: the perception result, and auxiliary information of the perception result. The auxiliary information is used to indicate the consistency relationship between the antenna ports based on which the perception result is obtained.

[0119] In some embodiments, the first node receives the perception result information.

[0120] In some embodiments, the second node obtains the sensing result by: for sensing signals respectively sent by n antenna ports with consistency, performing correlation calculation on the received n sensing signals to obtain a correlation calculation result, wherein the correlation calculation is used to eliminate the influence of random phases of the n antenna ports on the sensing result, and n is an integer greater than 1; and obtaining the sensing result according to the correlation calculation result.

[0121] Nowadays, a radio device usually has multiple transmitting antenna ports or receiving antenna ports. For multiple transmitting antenna ports or receiving antenna ports with good consistency, for example, a base station, the random phases of the multiple transmitting antenna ports or receiving antenna ports can be considered to be the same, and the random phases can be eliminated by performing correlation calculation on the channels of the multiple antenna ports.

[0122] This embodiment takes breathing monitoring as an example to illustrate the method for eliminating the random phases of multiple antenna ports. As shown in FIG. 6, a sending end 61 is a base station or a WiFi (Wireless Fidelity) device, and the multiple antenna ports of the device have consistency, that is, the random phases of the multiple antenna ports are consistent. A receiving end 62 is a terminal device, and the volume and cost of the terminal device are limited, and it is difficult to ensure that the random phases of the multiple antenna ports are consistent. When a target person 63 breathes, the sending end 61 sends signals to the target person 63 through the multiple antenna ports. For the sake of simplicity, it is assumed that the number of transmitting antenna ports of the sending end 61 is 2. Similarly, it is assumed that the number of receiving antenna ports of the receiving end is 2, and the signals are reflected and scattered to the receiving end 62 through the target person 63.

[0123] The sending end 61 sends sensing signals through two orthogonal antenna ports (that is, antenna port 1 and antenna port 2 shown in the figure), and the channel information of the two antenna ports can be respectively obtained at the receiving end 62. On the first receiving antenna port, the sensing signals from the two transmitting antenna ports can be received as h 11 =c 11 ej(2π(pattern11(t)+θ)),h 12 =c 12 ej(2π(pattern12(t)+θ)), where c is a channel amplitude, pattern(t) is the influence of the movement / respiration of the target person 63 on the channel phase, and θ is a random phase term. The correlation calculation is performed on the two, that is, R1=h 11 *h 12 =c 11 c 12ej(2π(pattern11(t)-pattern12(t))), where * represents conjugate multiplication. As can be seen from R1, the phase term of variable R1 after correlation calculation of the perceived signals of the two transmitting antenna ports has no random phase θ. Since pattern11(t) and pattern12(t) are not exactly the same, pattern11(t)-pattern12(t) can still reflect the movement / respiration regularity of the perceived target. Similarly, at the second receiving antenna port, the correlation function R2 of the signals of the two transmitting antenna ports can also be obtained. 21 *h 22 = c 21 c 22 ej(2π(pattern21(t)-pattern22(t))), and similarly, pattern21(t)-pattern22(t) can still reflect the movement / respiration regularity of the perceived target.

[0124] The R1 and R2 of the two receiving antenna ports are directly combined, for example, R1R2 is multiplied, so that the phase superposition of the two can further strengthen the phase change caused by the perceived target. The R1 and R2 of the two receiving antenna ports can also be respectively subjected to spectrum analysis to obtain the movement regularity of the perceived target, and then combined to eliminate the influence of noise.

[0125] As can be seen from the foregoing, for the perceived signals transmitted by multiple antenna ports with consistency, the receiving end of the perceived signals can perform correlation calculation on the multiple perceived signals received thereby to eliminate the influence of the random phases of the multiple antenna ports on the perceived results, so as to obtain more accurate perceived results, such as more accurate ranging or speed measurement results.

[0126] The present application takes into account that in some product implementations, multiple antenna ports / channels share a hardware channel, so that the multiple antenna ports / channels generate the same random phase or similar random phases. By using this feature, the random phase can be eliminated through correlation of the signals of the multiple antenna ports / channels. However, which antenna ports / channels share the hardware channel is often an implementation problem, which depends on the implementation of the transmitting end and cannot be known by the receiving end. Therefore, by sending the consistency information of the antenna ports / channels of the transmitting node to the receiving end, the receiving end can eliminate the random phase based on the multiple antenna ports / channels.

[0127] Of course, if the transmitting end eliminates or reduces the random phase difference between the antenna ports / channels by using some other enhancement technology, for example, a software algorithm, as long as the random phase difference is below a certain threshold value, the antenna ports / channels can also be considered to have consistency and be configured to the receiving end. In summary, in the present application, the implementation manner of the consistency of the transmitting antenna ports / channels is not restricted.

[0128] In some embodiments, the second node sends the sensing result information including the sensing result.

[0129] In some embodiments, the second node sends the sensing result information including the sensing result and auxiliary information of the sensing result, the auxiliary information being used to indicate a consistency relationship among antenna ports based on which the sensing result is obtained. Illustratively, the auxiliary information is used to indicate whether the sensing result is obtained based on a transmission signal of antenna ports having consistency. Illustratively, the auxiliary information is used to indicate which group or groups of antenna ports having consistency the sensing result is obtained based on. By carrying the auxiliary information of the sensing result in the sensing result information, the receiver of the sensing result information can know how the sensing result is obtained, so as to evaluate the accuracy of the sensing result.

[0130] In summary, the technical scheme provided by the embodiments of the present application tells the consistency relationship of the multiple antenna ports of the transmission end of the sensing signal to the reception end of the sensing signal, so that the reception end of the sensing signal can make correlation calculation on the sensing signal transmitted by the above-mentioned antenna ports having consistency, so as to eliminate the influence of the random phase of the multiple antenna ports of the transmission end on the sensing result, which helps to obtain a more accurate sensing result.
