Communication methods, communication devices and communication systems

[0001] This application claims priority to Chinese Patent Application No. 202411996679.4, filed with the China National Intellectual Property Administration on December 31, 2024, entitled "Communication Method, Communication Apparatus and Communication System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more specifically, to a communication method, communication device, and communication system. Background Technology

[0003] With the development and advancement of communication technologies, the Internet of Things, artificial intelligence, big data, and automation technologies are reshaping traditional industries and giving rise to intelligent applications such as smart cities and autonomous driving. Mobile communication systems are gradually evolving towards integrated sensing and communication (ISAC), meaning that future mobile communication systems will not only be able to provide communication services for various business needs of terminals, but also provide sensing services, becoming an important infrastructure supporting these emerging intelligent applications.

[0004] However, current mobile communication systems are mainly designed to provide communication services to terminals, and the corresponding mechanisms need to be improved in order for mobile communication systems to achieve ISAC. Summary of the Invention

[0005] This application provides a communication method, communication device, and communication system that can achieve targeted interference measurement, improve the accuracy of interference measurement, and thus improve the reliability of communication / sensing.

[0006] Firstly, a communication method is provided, which can be executed by a first node. The first node can be a communication device (such as a terminal, access network device, or core network device), or the first node can be a component applicable to the communication device (such as a chip, chip system, logic circuit, or software). The following explanation uses the execution of the method by the first node as an example.

[0007] The method includes: a first node sending first information, the first information being used to configure interference measurement, the first information also being used to indicate a first type among multiple interference measurement types; and the first node obtaining a first measurement report, the first measurement report including the measurement results of the interference measurement of the first type.

[0008] According to the above scheme, when the first node configures the interference measurement for the second node, it indicates the specific type of interference measurement. Only by accurately measuring different types of interference can the corresponding interference be effectively avoided / suppressed, enabling targeted interference measurement, improving the accuracy of interference measurement, and thus improving the reliability of communication / sensing.

[0009] For example, the first type is either a passive interference measurement type or an active interference measurement type.

[0010] In conjunction with the first aspect, in some embodiments of the first aspect, the first information is also used to indicate a first resource for measuring the first type of interference.

[0011] In one optional implementation, the first type is a passive interference measurement type, and acquiring the first measurement report includes: the first node transmitting a first signal on the first resource; and the first node receiving the first measurement report.

[0012] According to the above scheme, the first node and the second node can be two sensing nodes performing bi-base sensing, or two communication nodes communicating with each other. The passive interference measurement specifically measures the passive interference experienced by the first node when it sends signals (such as communication signals / sensing signals) to the second node. This effectively suppresses passive interference and improves the reliability of sensing and communication between the first and second nodes.

[0013] In another optional implementation, the first type is a passive interference measurement type, and the acquisition of the first measurement report includes: the first node measuring the signal received on the first resource to obtain the first measurement report.

[0014] According to the above scheme, the first node and the second node can be two sensing nodes performing bi-base sensing, or two communication nodes communicating. The passive interference measurement specifically measures the passive interference experienced by the second node when it sends signals (such as communication signals / sensing signals) to the first node. This effectively suppresses passive interference and improves the reliability of sensing and communication between the first and second nodes.

[0015] Optionally, in the two optional embodiments described above, the method further includes: a first node sending second information, the second information being used to instruct at least one interfering node to remain silent and / or not send signals on the first resource.

[0016] According to the above scheme, when performing passive interference measurement, the interfering node can be notified to remain silent to avoid active interference affecting the accuracy of the passive interference measurement results and improve the accuracy of passive interference measurement.

[0017] For example, remaining silent may include at least one of not sending a signal or sending a signal at a power level less than a power threshold.

[0018] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: a first node sending third information for configuring interference measurement, the third information further indicating that the interference measurement type is active interference measurement. The first node receives a second measurement report, the second measurement report including measurement results of the active interference measurement. The first node determines the at least one interfering node based on the second measurement report.

[0019] According to the above scheme, the interference node can be determined by the measurement results obtained during the active interference measurement process, so as to notify the interference node to remain silent during the passive interference measurement, thereby improving the accuracy of the passive interference measurement.

[0020] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: the first node determining a passive interference suppression strategy based on the first measurement report, the passive interference suppression strategy including at least one of spatial parameters, beam parameters, or power parameters for interference suppression.

[0021] According to the above scheme, the first node can obtain the passive interference measurement results based on the first measurement report, determine the passive interference suppression strategy based on the passive interference measurement results, and achieve targeted interference suppression to improve the reliability of sensing and communication.

[0022] In conjunction with the first aspect, in some embodiments of the first aspect, the first type is an active interference measurement type, and obtaining the first measurement report includes: the first node measuring the signal received on the first resource and obtaining the first measurement report.

[0023] According to the above scheme, the first node can be a sensing node that performs single-base sensing measurements. This method enables the measurement of active interference received during single-base sensing measurements, thereby achieving interference suppression.

[0024] In conjunction with the first aspect, in some embodiments of the first aspect, the first node does not send signals on the first resource.

[0025] According to the above scheme, when the first node performs active interference on the first resource, it does not transmit a signal on the first resource; that is, the first node receives a signal on the first resource but does not transmit a signal. This avoids the first node's own transmitted signal affecting the active interference measurement results, thus preventing inaccurate measurement results.

[0026] Secondly, a communication method is provided, which can be executed by a second node. The first node can be a communication device (such as a terminal, access network device, or core network device), or the second node can be a component applicable to the communication device (such as a chip, chip system, logic circuit, or software). The following explanation uses the execution of the method by the second node as an example.

[0027] The method includes: a second node receiving first information, the first information being used to configure interference measurement, and the first information further being used to indicate a first type among multiple interference measurement types; the second node sending a first measurement report, the first measurement report including the measurement results of the first type of interference measurement.

[0028] In conjunction with the second aspect, in some embodiments of the second aspect, the first type is a passive interference measurement type.

[0029] In conjunction with the second aspect, in some embodiments of the second aspect, the first information is also used to indicate a first resource for measuring the first type of signal interference.

[0030] In one optional implementation, the first type is a passive interference measurement type, and sending the first measurement report includes: the second node measuring the signal received on the first resource to obtain the first measurement report; and the second node sending the first measurement report.

[0031] In another alternative implementation, the first type is a passive interference measurement type, whereby the second node transmits a second signal on the first resource. The second node receives the echo signal of the second signal. The second node then transmits a first measurement report, which is obtained by measuring the echo signal.

[0032] In conjunction with the second aspect, in some embodiments of the second aspect, the first type is an active interference measurement type, and sending the first measurement report includes: the second node measuring the signal received on the first resource to obtain the first measurement report. The second node then sends the first measurement report.

[0033] Optionally, the second node may remain silent on the first resource.

[0034] In conjunction with the second aspect, in some embodiments of the second aspect, the method further includes: a second node receiving third information for configuring interference measurement, the third information also indicating that the interference measurement type is active interference measurement. The second node then sends a second measurement report, the second measurement report including the measurement results of the active interference measurement.

[0035] Thirdly, a communication device is provided. In one design, the device may include modules corresponding to the methods / operations / steps / actions described in the first aspect or any embodiment of the first aspect. These modules may be hardware circuits, software, or a combination of hardware circuits and software.

[0053] To facilitate understanding of the embodiments of this application, the following description is provided first:

[0054] In this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information for the purpose of instructing A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0055] In this application, " / " can indicate that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" can be used to describe three relationships between the related objects. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0056] In this application, "at least one" means one or more, and "more than one" means two or more, such as three, four, or more. Similar expressions (such as at least one, at least one, etc.) are used in the same way. "At least one of the following," "one or more of the following," or similar expressions refer to any combination of these items, which may include only a single item or a combination of multiple items. For example, at least one of a, b, or c can mean: a, or b, or c; a and b; or a and c; or b and c; or a, b, and c. Where a, b, and c can be single or multiple.

[0057] In this application, for the convenience of describing the technical solutions of the embodiments of this application, the terms "first" and "second" may be used to distinguish them. The terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0058] In this application, the words "exemplary," "example," or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary," "example," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. The use of the words "exemplary," "example," or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0059] In this application, "sending information / data" only indicates the direction of information / data transmission, including direct transmission via the device's communication interface (such as an air interface, or simply air interface). "Sending" can also be understood as the "output" of a module interface. "Sending" can include indirect transmission by the processing unit through the communication interface, meaning that after the processing unit outputs information / data through the module interface, it is transmitted to the device's communication interface and then sent out. "Receiving information / data" only indicates the direction of information / data transmission, including direct reception via the communication interface. "Receiving" can also be understood as the "input" of a module interface. "Receiving information / data" can include indirect reception by the processing unit through the communication interface, meaning that after the communication interface receives information / data, it is transmitted to the processing unit's module interface and then input to the processing unit. "Sending information / data to… (such as a terminal)" can be understood as the destination of the information being the terminal. It can include sending information / data directly or indirectly to the terminal. "Receiving information / data from… (such as a terminal)" can be understood as the source of the information being the terminal, and can include receiving information / data directly or indirectly from the terminal. Information / data may undergo necessary processing, such as format changes, between the source and destination, but the destination can understand the valid information / data from the source. Similar statements in this application can be understood in a similar way, and will not be repeated here.

[0060] The technical solutions of this application can be applied to various communication systems, such as 4G communication systems, 5G communication systems, satellite communication systems, wireless fidelity (WiFi) systems, and the solutions provided in this application can also be applied to future communication systems or other communication systems. This application does not limit these applications.

[0061] Figure 1 illustrates another possible, non-limiting system diagram. As shown in Figure 1, the communication system 10 includes a radio access network (RAN) 100, a core network (CN) 200, and a data network (DN) 300. RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. Access network node (or RAN node) 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and access network node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0062] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future evolution systems. RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0063] Access network node 110, sometimes also referred to as network equipment, access network device, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple access network nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of access network node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. Access network node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0064] In one possible scenario, the access network node can be a base station, such as an evolved NodeB (eNodeB), a next-generation NodeB (gNB), or a base station in a future mobile communication system. The access network node can be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Alternatively, the access network node can be an access point (AP), a transmission reception point (TRP), or an access node in a WiFi system. Optionally, the access network node can also be a server, a wearable device, a vehicle, or in-vehicle equipment. For example, the access network device in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of the access network node in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The access network node in this application may also be a logical node, logical module, or software that can implement all or part of the functions of the access network node.

[0065] In another possible scenario, multiple access network nodes collaborate to assist the terminal in achieving wireless access, with each access network node performing a portion of the base station's functions. For example, access network nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0066] A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used for communication in various scenarios. These scenarios include, but are not limited to, at least one of the following: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communications (mMTC), D2D, V2X, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearables, intelligent transportation, sensing terminals, terminals integrating communication and sensing, or smart cities, etc. Terminals can be mobile phones (as shown in Figure 1, 120a, 120j, and 120e), tablets, computers with wireless transceiver capabilities (as shown in Figure 1, 120g), customer-premises equipment (CPE), point-of-sale (POS) machines, wearable devices, vehicles (as shown in Figure 1, 120b), drones, helicopters, airplanes (as shown in Figure 1, 120i), ships, robots, robotic arms, sensors, detectors, or smart home devices (as shown in Figure 1, 120h), etc.

[0067] In this application embodiment, the communication method provided by this application is shown from the perspective of interaction between the terminal and the access network node, but this application does not limit the executing subject of the method. The terminal can be replaced by a module (such as a chip, chip system, processor, logic circuit, or software) configured in (or used for) the terminal, and the access network node can be replaced by a module (such as a chip, chip system, processor, logic circuit, or software) configured in (or used for) the access network device. When the executing subject is a module in the terminal or access network node, receiving / transmitting can be understood as input / output, that is, the module communicates with other modules or components of the terminal or access network node. In addition, the operation performed by a single executing subject can also be divided into operations performed by multiple executing subjects, which can be logically and / or physically separated. For example, the operation performed by the access network node can be divided into operations performed by at least one of CU, DU, RU, etc.

[0068] The relevant technologies and terms involved in the embodiments of this application will be explained below.

[0069] Sensing technology, applied to mobile communication systems, can utilize the radio frequency signals of the communication system for environmental perception, enabling functions such as target detection, environmental imaging, or localization. Sensing can be achieved through single-base sensing and dual-base sensing.

[0070] I. Mono-static Sensing

[0071] Single-base sensing refers to a system where the transmitter and receiver are located at the same or very close locations, transmitting signals and receiving signals reflected back from the target to achieve single-base sensing. For example, the transmitter and receiver can be located on the same device, achieving single-base sensing through self-transmission and self-reception. Single-base sensing is applied in mobile communication systems, where access network nodes or terminals can independently implement single-base sensing.

[0072] II. Bi-static Sensing

[0073] Two-base sensing refers to a system where the transmitter and receiver are located in different positions. Because the transmitter and receiver are separate, the target can be observed from different angles, improving target detection and identification capabilities. For example, the transmitter and receiver can be located in different devices. Two-base sensing is applied in mobile communication systems, and various combinations such as access network nodes and terminals, access network nodes with each other, and terminals with each other can all implement two-base sensing.

[0074] The accuracy of perception measurements can be reduced by non-target interference in the environment. Therefore, accurate measurement of interference in the environment and interference avoidance / suppression are crucial to ensuring the accuracy of perception measurements.

[0075] Currently, mobile communication systems define a resource for measuring and evaluating interference, called Channel State Information-Interference Measurement (CSI-IM) resource. Specifically, after the serving base station configures CSI-IM resources for a terminal, the serving base station does not transmit signals on these resources, while neighboring cell base stations transmit signals on them. The terminal receives signals on these CSI-IM resources and can measure the interference signal strength of neighboring cells. The base station can then use the obtained interference signal strength from neighboring cells to employ appropriate interference avoidance measures. Therefore, interference measurement based on CSI-IM resources is a method for measuring active interference.

[0076] Active interference refers to interference caused by signals actively generated by a transmitting device. In addition, passive interference, also known as passive signal interference, also exists in the channel. Passive interference refers to interference caused by objects or materials in the environment reflecting, absorbing, scattering, or attenuating wireless signals.

[0077] In sensing scenarios, both active and passive interference can significantly impact the accuracy of sensing measurements. For example, as shown in Figure 2, taking the bi-baseline sensing measurement performed by the first access network node and the terminal as an example, the first access network node sends a sensing signal, and the terminal receives the sensing signal to achieve sensing of the target, the UAV 201 shown in Figure 2, such as target identification or localization. However, the signal sent by the second access network node may cause active interference to the sensing signal. Furthermore, the sensing signal may be absorbed, scattered, reflected, or attenuated by the building 202 next to the UAV 201 before reaching the terminal, resulting in the sensing signal received by the terminal being affected by both active and passive interference.

[0078] Accurate measurement of different types of interference is essential for effectively avoiding / suppressing such interference, a mechanism currently lacking in mobile communication systems. Therefore, this application proposes indicating the specific type of interference to be measured during the interference measurement configuration, enabling targeted interference measurement, improving its accuracy, and ultimately enhancing the reliability of communication / sensing.

[0079] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0080] Figure 3 is a schematic flowchart of a communication method 300 provided in an embodiment of this application. In this communication method 300, the first node can be a network-side communication node. For example, the first node can be an access network node (such as a base station, CU, etc.) or a core network node (such as a sensing function (SF) node, etc.), but this application is not limited to these. The second node can be a network-side communication node or a terminal. For example, when the second node is a network-side communication node, the second node can be an access network node (such as a base station, DU, etc.). However, this application is not limited to these. The first node / second node can also be a component configured in a corresponding communication device (such as a network device or a terminal). For example, the component can be a chip, a chip system, a logic circuit, or software, etc.

[0081] The method 300 may include, but is not limited to, the following steps:

[0082] S310, the first node sends first information to the second node, the first information being used to configure interference measurement, and the first information also being used to indicate a first type among a variety of interference measurement types.

[0083] Accordingly, the second node receives the first information from the first node and determines to perform the first type of interference measurement based on the first information.

[0084] For example, the various interference measurement types may include passive interference measurement types and active interference measurement types. These various interference measurement types may also include other interference measurement types, which are not limited herein.

[0085] For example, an identifier for each of several interference measurement types can be predefined through the protocol, and this first information includes the identifier of the first type. The second node determines to perform the first type of interference measurement based on the identifier of the interference measurement type contained in the first information. Taking the multiple interference measurement types as an example, which include both passive and active interference measurements, the identifier for the passive interference measurement type is 0, and the identifier for the active interference measurement type is 1. If the identifier of the interference measurement type contained in the first information is 0, the second node determines to perform a passive interference measurement; if the identifier of the interference measurement type contained in the first information is 1, the second node determines to perform an active interference measurement.

[0086] For example, the first information may include measurement event configuration information, specifically, the measurement event configuration information is used to indicate that the type of interference measurement is a first type.

[0087] Specifically, the first information is further used to configure a first resource for the first type of interference measurement. For example, the first information includes measurement object configuration information used to configure the first resource.

[0088] It should be noted that the first information may also indicate the type of interference measurement or the first resource in other ways. This application does not limit the specific form in which the first information indicates the type of interference measurement or the first resource.

[0089] S320, the second node acquires a first measurement report, which includes measurement results of a first type of interference measurement.

[0090] The first measurement report can be a measurement report obtained by the first node based on the signal received by the first resource, and the second node can obtain the first measurement report from the first node. Alternatively, the first measurement report can be a measurement report obtained by the second node based on the signal received on the first resource. The following details the first type of interference measurement, which includes active interference measurement and passive interference measurement, respectively.

[0091] Example 1: The first type of interference measurement can be an active interference measurement.

[0092] The first node configures the second node to perform active interference measurement by sending a first message to the second node. Specifically, this first resource is used for active interference measurement.

[0093] The first node can interact with at least one node to collaboratively perform active interference measurement. For example, the at least one node may be a node that might actively interfere with the second node. The first node notifies the at least one node to send a signal on a first reference signal resource so that the second node can measure the active interference on the first reference signal resource. The at least one node includes a third node. The communication method 400 shown in Figure 4 will be described in detail below. It should be understood that this method 400 is described using the third node among at least one nodes as an example. If the at least one node also includes other nodes, the implementation method for the third node can be referred to, and will not be repeated here. The method 400 includes:

[0094] S401, the first node sends first information to the second node, which is used to configure active interference measurement. Accordingly, the second node receives the first information from the first node.

[0095] The first information specifically indicates that the interference measurement type is active interference measurement (i.e., an example of the first type of interference measurement). The second node determines to perform active interference based on the first information. Other functions of the first information can be found in the description of S301, and will not be repeated here.

[0096] S402, the first node sends interference measurement cooperation information to the third node. Correspondingly, the third node receives the interference measurement cooperation information from the first node.

[0097] The first node can use this interference measurement cooperation information to notify the third node to cooperate in performing interference measurements. This interference cooperation information can indicate a first resource and the type of interference measurement. That is, if the interference measurement cooperation information indicates that the interference measurement type is active interference measurement, then after receiving the interference measurement cooperation information, the third node can determine to perform active interference measurement on the first resource. Specifically, the third node determines to send a reference signal on the first resource so that the second node can measure the active interference.

[0098] It should be noted that this application does not restrict the order in which the first node executes S401 and S402. S402 can be executed after S401 or before S401.

[0099] S403, the third node sends a signal on the first resource. Correspondingly, the second node receives the signal on the first resource and, based on the received signal, obtains a first measurement report.

[0100] Specifically, the third node sends a signal on the first resource based on the interference measurement cooperation information, and the second node receives the signal on the first resource based on the first information.

[0101] In implementation 1-1, the first node and the second node can be two sensing nodes performing bibase sensing measurements, and in the sensing measurements, the first node sends a sensing signal to the second node. And / or, the first node and the second node are two communication nodes communicating, and in the communication, the first node sends a communication signal to the second node. The first node remains silent on the first resource, or in other words, the first node does not send a signal on the first resource. The third node sends a signal on the first resource, and the second node performs active interference measurements on the first resource.

[0102] For example, the first node can be a first access network node, and the second node can be a terminal. That is, the first access network node is the access network node that provides network services to the terminal, or it can be the access network node that manages the serving cell of the terminal. The first access network node and the terminal can be either two sensing nodes performing bi-baseline sensing measurements or two communication nodes communicating. The third node can be a second access network node, such as the second access network node managing the neighboring cells of the terminal's serving cell. The second access network node transmits signals on the first resource, while the first access network node does not transmit signals on the first resource. The terminal receives signals on the first resource and measures the active interference of the second access network node.

[0103] For example, the first node and the second node can be two sensing nodes performing bi-base sensing measurements. For instance, a sensing node can be an access network node or a terminal; both sensing nodes can be terminals, or both can be access network nodes, or one can be a terminal and the other an access network node. The third node can be an interfering node that actively interferes with the sensing node (i.e., the second node) receiving the sensing signal. This interfering node could be either a terminal or an access network node.

[0104] In implementation methods 1-2, the second node can be a sensing node performing single-base sensing measurements. When the second node performs active interference on the first resource, it does not transmit a signal on the first resource; that is, the second node receives a signal on the first resource but does not transmit a signal. The third node transmits a signal on the first resource, and the second node performs active interference measurements on the first resource. This avoids the signal transmitted by the second node itself affecting the active interference measurement results, thus preventing inaccurate measurement results.

[0105] For example, the second node can be an access network node performing single-base sensing, specifically, this access network node can be a base station or DU, etc., and the first node can be a core network node (such as an SF node), or the second node can be a DU performing single-base sensing. The first node can be a CU. This access network node does not transmit signals on the first resource in order to receive signals on the first resource to measure active interference. The third node can be other access network nodes that interfere with this access network node.

[0106] For example, the second node could be a terminal performing single-base sensing, and the first node could be an access network node or a core network node. This terminal does not transmit signals on the first resource in order to receive signals on the first resource to measure active interference. The third node could be an access network node or terminal that may be subject to interference.

[0107] The second node obtains a first measurement report based on the signal received on the first resource. This first measurement report includes the measurement results of active interference measurements.

[0108] The measurement results of active interference measurements may include one or more of the following:

[0109] Reference signal receiving power (RSRP), signal to interference plus noise ratio (SINR), received signal strength indicator (RSSI), or reference signal received quality (RSRQ).

[0110] In one example, the measurement parameters included in the measurement results for each of the various interference measurement types can be predefined through the protocol.

[0111] Based on the first information, the second node determines that the interference measurement type is active interference measurement. After receiving the signal on the first resource, the second node measures the predefined measurement parameters corresponding to active interference measurement, obtains the corresponding measurement parameters, and generates a first measurement report. This first measurement report includes the measurement parameters corresponding to the active interference measurement obtained by the second node.

[0112] In another example, the first information is also used to indicate the measurement parameters included in the first measurement report.

[0113] The second node measures the corresponding measurement parameters based on the signals received on the first resource, according to the measurement parameters indicated by the first information, and generates a first measurement report.

[0114] S404, the second node sends a first measurement report to the first node. Accordingly, the first node receives the first measurement report from the second node.

[0115] Based on the first measurement report, the first node can determine the measurement results of the active interference measurement performed by the second node, thereby determining the active interference situation of the third node on the second node.

[0116] Optionally, in step S405, if the first node determines that the third node is actively interfering with the second node, the first node can determine an active interference suppression strategy. Specifically, the first node determines that the third node is actively interfering with the second node based on the fact that the interference intensity of the third node is greater than or equal to an interference intensity threshold, wherein the interference intensity can be determined by the first node based on a first measurement report.

[0117] In embodiment 1-1 described above, the first node and the second node are two nodes that perform bistatic sensing measurements and / or communication. The first node can communicate with the second node and / or perform sensing measurements (such as transmitting sensing signals) with the second node according to an active interference suppression strategy.

[0118] Active interference suppression strategies may include interference suppression through at least one of time-domain resources, frequency-domain resources, code-domain resources, or power. Specifically, the first node may negotiate and determine an active interference suppression strategy with the third node. For example, through information exchange, on resources (such as time-domain resources and / or time-frequency resources) where the first node and the second node transmit communication / sensing signals, the third node may perform one or more of the following: power control, code division multiplexing of the resource, or not transmitting a signal. For example, the signal transmission power of the third node on the resource may not exceed the interference cooperation power threshold, but this application is not limited to this.

[0119] In embodiments 1-2 described above, the second node is a sensing node performing single-base sensing measurements. The first node, based on an active interference suppression strategy, determines the sensing resources for the second node's single-base sensing through operations such as coordinating the allocation of time-domain, frequency-domain, and code-domain resources and adjusting transmit power with the interfering third node. These sensing resources can be at least one of time-domain, frequency-domain, code-domain, or power resources capable of suppressing interference. The first node can send configuration information to the second node to configure the sensing resources for single-base sensing. The second node then performs single-base sensing measurements based on these resources. This approach avoids / suppresses active interference from the third node on the second node's single-base sensing measurements, improving the accuracy and reliability of the second node's single-base sensing.

[0120] According to the above scheme, the first node notifies the second node to perform active interference measurement via a first message. Upon receiving the first message, the second node can determine whether to perform active interference measurement based on the interference measurement type indicated by the first message and report a measurement report containing the measurement results of the active interference measurement. Through the indication of the first message, the first and second nodes reach a consensus on the interference measurement type and implement the corresponding interference measurement. This enables targeted interference measurement, improves the accuracy of interference measurement, and thus enhances the reliability of communication / sensing.

[0121] The above detailed explanation uses the first type of interference measurement as an example of active interference measurement. The following explanation uses the first type of interference measurement as an example of passive interference measurement.

[0122] Example 2: The first type of interference measurement can be a passive interference measurement.

[0123] Passive interference measurement primarily measures interference caused by passive interference targets in the environment. For example, the measurement results of passive interference measurement can be applied to passive interference suppression in sensing measurements. For instance, a node performing sensing measurements can perform passive interference measurements even when the target to be measured is absent, so that passive interference suppression can be achieved based on the passive interference measurement results during sensing measurements. However, this application is not limited to this; the measurement results of passive interference measurement can also be applied to passive interference suppression in communication.

[0124] When the interference measurement is a passive interference measurement, the following implementation methods may be included, but are not limited to, those described in detail below.

[0125] In implementation method 2-1, the first node and the second node are two sensing nodes performing bibase sensing or two communication nodes communicating. This passive interference measurement specifically measures the passive interference experienced by the first node when it sends a signal (such as a communication signal / sensing signal) to the second node. The following is a detailed description of the communication method 500 shown in Figure 5. This method 500 includes, but is not limited to, the following steps:

[0126] S501, the first node sends first information to the second node, which is used to configure passive interference measurement. Accordingly, the second node receives the first information from the first node.

[0127] Specifically, the first information can indicate that the interference measurement type is a passive interference measurement type (i.e., an example of the first type of interference measurement). Based on this first information, the second node determines to perform a passive interference measurement. Other functions of the first information can be found in the description of S301, and will not be repeated here. This first information is also used to configure a first resource, which is the resource for the first node to transmit signals and the resource for the second node to measure passive interference.

[0128] S502, the first node sends interference measurement cooperation information to the third node. Correspondingly, the third node receives the interference measurement cooperation information from the first node.

[0129] The first node can use this interference measurement cooperation information to notify the third node to cooperate in performing interference measurement. This interference cooperation information can indicate the first resource and the type of interference measurement. That is, if the interference measurement cooperation information indicates that the interference measurement type is passive interference measurement, then after receiving the interference measurement cooperation information, the third node can determine to perform passive interference measurement on the first resource. Specifically, the third node determines to remain silent on the first resource so that the second node can measure the passive interference.

[0130] Based on the preceding description of the embodiment shown in Figure 4, when the third node receives interference measurement cooperation information indicating that the interference measurement type is active interference measurement, the third node sends a signal on the resource indicated by the interference measurement cooperation information so that the second node can measure the active interference. When the third node receives interference measurement cooperation information indicating that the interference measurement type is active interference measurement, the third node remains silent on the resource indicated by the interference measurement cooperation information so that the second node can measure passive interference. In other words, the interference measurement cooperation method performed by the third node varies depending on the interference measurement type indicated by the interference measurement cooperation information.

[0131] It should be noted that this application does not restrict the order in which S501 and S502 are executed in the first node. S502 can be executed after S501 or before S501.

[0132] The third node acts as an active interference node to the second node. The first node can notify the active interference node of the second node to perform passive interference measurement cooperation through interference measurement cooperation information. This allows the active interference node to remain silent on the resources used by the second node to measure passive interference, preventing active interference signals from affecting the passive interference measurement of the second node. This improves the accuracy of the passive interference measurement of the second node.

[0133] Specifically, the first node determines that the third node is an active interference node of the second node based on the active interference measurement report of the second node. Specifically, the first node can configure the second node to perform active interference measurement and notify the third node to perform active interference measurement cooperation, thereby obtaining the active interference measurement report from the second node. Based on the active interference measurement results in the active interference measurement report, the first node can determine that the third node is an active interference node of the second node. That is to say, before S501, the first node can execute the active interference measurement process in the communication method 400 shown in Figure 4 above. For details, please refer to the previous description of the communication method 400 shown in Figure 4; it will not be repeated here.

[0134] S503, the third node remains silent on the first resource, the first node sends a signal on the first resource, and correspondingly, the second node receives a signal on the first resource. Based on the received signal, a first measurement report is obtained.

[0135] The third node remains silent on the first resource, meaning it does not transmit any signals on the first resource. The first node transmits signals on the first resource, and the second node receives signals on the first resource. The received channel includes multipath signals, i.e., signals that reach the second node through multiple transmission paths. Signals other than direct paths are signals that have been absorbed, reflected, or scattered by passive interference targets before reaching the second node. The second node can determine the measurement results of the passive interference measurement based on signals other than direct paths and generate a first measurement report, which includes the measurement results of the passive interference measurement.

[0136] Specifically, the third node sends a signal on the first resource based on the interference measurement cooperation information, and the second node receives the signal on the first resource based on the first information.

[0137] For example, the measurement results of this passive interference measurement may include at least one of the following: multipath parameters or channel information used to characterize the passive interference channel. Multipath parameters may include, but are not limited to, one or more of the following: transmission delay, signal strength, phase, and signal angle of arrival for each transmission path. Channel information of the interference channel may include, but is not limited to, one or more of the following: channel feature vector, channel eigenvalue, channel basis vector, and combination coefficients of basis vectors used to characterize the passive interference channel.

[0138] In one example, the measurement parameters (such as multipath parameters and / or channel information) included in the measurement results for each of the various interference measurement types can be predefined through the protocol.

[0139] Based on the first information, the second node determines that the interference measurement type is passive interference measurement. After receiving the signal on the first resource, the second node measures the predefined measurement parameters corresponding to the passive interference measurement and generates a first measurement report. This first measurement report includes the measurement parameters corresponding to the passive interference measurement obtained by the second node.

[0140] In another example, the first information is also used to indicate the measurement parameters included in the first measurement report.

[0141] The second node measures the corresponding measurement parameters based on the signals received on the first resource, according to the measurement parameters indicated by the first information, and generates a first measurement report.

[0142] S504, the second node sends a first measurement report to the first node. Correspondingly, the first node receives the first measurement report from the second node.

[0143] Based on the first measurement report, the first node can obtain the measurement results of the passive interference measurement performed by the second node.

[0144] S505, the first node determines the passive interference suppression strategy based on the measurement results of the passive interference measurement.

[0145] For example, the passive interference suppression strategy may include, but is not limited to, at least one of the following: precoding parameters, spatial parameters, beam parameters, or power parameters. For instance, the first node may precode the communication signal / sensing signal to be sent to the second node according to the precoding parameters before sending it to the second node. Alternatively, the first node may determine the transmission beam of the communication signal / sensing signal to be sent to the second node according to the beam parameters, and then send the communication signal / sensing signal to the second node through that beam. The first node may also send the communication signal / sensing signal to the second node according to the power parameters. These methods effectively suppress passive interference and improve the reliability of sensing and communication between the first and second nodes.

[0146] For example, in the method 500 shown in Figure 5, the first node can be a first access network node, the second node can be a terminal, and the third node can be a second access network node. The first access network node is the access network node that provides network services to the terminal, and the serving cell of the terminal is a cell managed by the first access network. The second access network node is an access network node that actively interferes with the signal received by the terminal. However, this application is not limited to this. The first node, second node, and third node can be three access network nodes or three terminals.

[0147] In implementation method 2-2, the first node and the second node are two sensing nodes performing bi-base sensing, or two communication nodes communicating. The passive interference measurement specifically measures the passive interference experienced by the second node when it sends a signal (such as a communication signal / sensing signal) to the first node. The following is a detailed description of the communication method 600 shown in Figure 6. This method 600 includes, but is not limited to, the following steps:

[0148] S601, the first node sends first information to the second node, the first information being used to configure passive interference measurement, and correspondingly, the second node receives the first information from the first node.

[0149] Specifically, this first information can indicate that the interference measurement type is a passive interference measurement type (i.e., an example of the first type of interference measurement). This first information is also used to configure a first resource, which, unlike S501 above, is a resource for the second node to transmit signals, and also a resource for the first node to measure passive interference. The second node can determine, based on the first information, to transmit signals on the first resource for performing passive interference measurements. Other functions of the first information can be found in the description of S301, and will not be repeated here.

[0150] In step S602, the first node sends interference measurement cooperation information to the third node, and correspondingly, the third node receives the interference measurement cooperation information from the first node. Step S602 is the same as step S502 above; for specific implementation, please refer to S502, and it will not be repeated here.

[0151] S603, the third node remains silent on the first resource, the second node sends a signal on the first resource, the first node receives a signal on the first resource, and obtains a first measurement report based on the received signal.

[0152] The specific method by which the first node obtains the first measurement report based on the received signal can be referred to the method by which the second node obtains the first measurement report based on the received signal in S503 above, and will not be repeated here.

[0153] In one implementation, the first node can send a first measurement report to a second node, which then determines a passive interference suppression strategy based on the passive interference measurement results in the first measurement report. The second node can then send communication signals / sensing signals to the first node according to this passive interference suppression strategy. Specific implementation details can be found in the embodiments of S504 and S505, which will not be elaborated upon here.

[0154] In another implementation, S605 and S606 may be included as follows.

[0155] Optionally, in S604, the first node determines a passive interference suppression strategy based on the measurement results of the passive interference measurement.

[0156] For example, the passive interference suppression strategy may include, but is not limited to, at least one of the precoding parameters, spatial parameters, beam parameters, or power parameters for interference suppression. Since the passive interference measurement in method 600 specifically measures the passive interference when the second node transmits a signal to the first node, the first node can determine the passive interference suppression strategy used when the second node transmits a signal to the first node.

[0157] Optionally, in step S605, the first node sends a passive interference suppression strategy to the second node. Correspondingly, the second node receives the passive interference suppression strategy from the first node.

[0158] The second node can send communication / sensing signals to the first node based on this passive interference suppression strategy. This effectively suppresses passive interference and improves the reliability of sensing and communication between the first and second nodes.

[0159] For example, in the method 600 shown in Figure 6, the first node can be a first access network node, the second node can be a terminal, and the third node can be a second access network node. The first access network node is the access network node that provides network services to the terminal, and the serving cell of the terminal is a cell managed by the first access network. The second access network node is an access network node that actively interferes with the signal received by the terminal. However, this application is not limited to this. The first node, second node, and third node can be three access network nodes or three terminals.

[0160] In implementation methods 2-3, the second node is a sensing node performing single-base sensing measurement, specifically measuring the passive interference experienced by the second node during single-base sensing. The first node can be the node controlling the second node to perform single-base sensing. The third node is the active interference node of the second node. The following is a detailed description of the communication method 700 shown in Figure 7. This method 700 includes, but is not limited to, the following steps:

[0161] S701, the first node sends first information to the second node, which is used to configure passive interference measurement, and the second node receives the first information from the first node accordingly.

[0162] Specifically, this first information can indicate that the interference measurement type is a passive interference measurement type (i.e., an example of the first type of interference measurement). This first information is also used to configure a first resource. Unlike S501 and S601 above, this first resource is a resource where the second node transmits a signal, and the second node receives the echo signal of this signal, thereby obtaining a measurement report based on the echo signal. The second node can determine, based on the first information, to perform a self-transmitting and self-receiving passive interference measurement on the first resource. Other functions of the first information can be found in the description of S301, and will not be repeated here.

[0163] In step S702, the first node sends interference measurement cooperation information to the third node. Correspondingly, the third node receives this interference measurement cooperation information from the first node. Step S702 is the same as step S502 described above; for specific implementation, please refer to S702, and it will not be repeated here.

[0164] S703, the third node remains silent on the first resource, the second node sends a signal on the first resource and receives the echo signal of the signal, and obtains the first measurement report based on the received echo signal.

[0165] The specific method by which the second node obtains the first measurement report based on the received echo signal can be referred to in the previous section S503, which describes how the second node obtains the first measurement report based on the received signal. It will not be repeated here.

[0166] S704, the second node sends a first measurement report to the first node. Accordingly, the first node receives the first measurement report from the second node.

[0167] S705, the first node determines the passive interference suppression strategy based on the measurement results of the passive interference measurement.

[0168] For example, the passive interference suppression strategy may include, but is not limited to, at least one of the precoding parameters, spatial parameters, beam parameters, or power parameters for interference suppression. Since the passive interference measurement in method 700 specifically measures the passive interference during single-base sensing measurement by the second node, the first node can determine the passive interference suppression strategy used by the second node during single-base sensing measurement based on the passive interference measurement results.

[0169] S706, the first node sends a passive interference suppression strategy to the second node. Correspondingly, the second node receives the passive interference suppression strategy from the first node.

[0170] The second node can perform single-base sensing measurements according to the passive interference suppression strategy. Specifically, the second node transmits a sensing signal according to the passive interference suppression strategy, such as transmitting a sensing signal based on at least one of precoding parameters, spatial parameters, beam parameters, or power parameters, and receives the echo signal of the sensing signal, realizing single-base sensing measurements based on the echo signal. By having the second node perform single-base sensing measurements based on the passive interference suppression strategy, passive interference can be effectively suppressed, improving the reliability of the single-base sensing measurements of the second node.

[0171] For example, in the method 700 shown in Figure 7, the first node can be a core network node (such as an SF node), the second node can be an access network node or terminal, and the third node can be an access network node or terminal that interferes with the second node. Alternatively, the first node, the second node, and the third node can all be access network nodes, such as the first node being a CU, the second node being a DU, and the third node being another access network node that actively interferes with the second node.

[0172] It is understood that, in order to implement the functions in the above embodiments, the access network node and terminal include hardware structures and / or software modules corresponding to perform each function. Those skilled in the art should readily recognize that, based on the units and method steps of the various examples described in conjunction with the embodiments disclosed in this application, this application can be implemented in hardware or a combination of hardware and computer software.
