Current interference measurement primarily focuses on communication scenarios; however, there are no suitable interference measurement solutions for sensing scenarios or integrated sensing and communication (ISAC) scenarios.

[0004] Therefore, how to perform interference measurement in sensing scenarios or ISAC has become an urgent technical problem to be solved. Summary of the Invention

This application also provides corresponding apparatus, computer-readable storage media, and computer program products.

[0006] This application provides a communication method applied to a first communication device. The first communication device can refer to the device itself, a component within the device responsible for communication and / or sensing functions (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. The circuit or chip responsible for communication and / or sensing functions can be a modem chip (also known as a baseband chip), a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip. The device can be a network device or a terminal device, and the network device can include access network equipment or core network equipment. The method includes: sending information about at least one first measurement resource to a second communication device, the at least one first measurement resource being used to measure interference signals, the interference signals including communication signals and / or sensing signals; and receiving an interference measurement report, the interference measurement report being used for interference management.

[0007] In this application, the first communication device can be a central node, a sensing function (SF) network element, a sensing management function (SMF) network element, or a device corresponding to such a device. The central node can be a node that configures sensing parameters for the transmitting end or receiving end of the sensing signal, and / or a node that summarizes the sensing results. The central node can be a network device or a chip within a network device; of course, it can also be other types of devices. The SF network element / SMF network element can be a node used for sensing function management, or a node that performs all or part of the sensing function. The function and form of the SF network element / SMF network element can be the same as or similar to the central node. The transmitting end is also called a transmitting node, and the receiving end is also called a receiving node. A transmitting node refers to a node used to transmit sensing signals, and a receiving node refers to a node used to receive the echo signals of the sensing signals.

[0008] In this application, the second communication device can be a device corresponding to a receiving node or a sensing node; wherein, a sensing node refers to a node that integrates a transmitting end of sensing signals and a receiving end of echo signals.

[0009] In this application, the transmitting node, receiving node, or sensing node can all be access network equipment or chips in access network equipment, terminal equipment or chips in terminal equipment.

[0010] In this application, the information of the first measurement resource is used to indicate a resource for measuring interfering signals that interfere with sensing or communication signals. The first measurement resource can measure interfering signals, and there can be one or more interfering signals. The information of the first measurement resource can be sent separately or included in resource configuration or report configuration.

[0011] In this application, the interference measurement report may include multiple pieces of information obtained through interference measurements, such as: channel state information reference signal received power (CSI-RSRP), channel state information received signal strength indication (CSI-RSSI), channel state information signal to interference plus noise ratio (CSI-SINR), sensing reference signal reference signal received power (sensing RS-RSRP), and cross link interference received signal strength indication (CLI-RSSI), etc. Therefore, the first communication device can perform interference management based on the interference measurement report.

[0012] In this application, interference management may include interference coordination or interference cancellation. Interference coordination refers to the first communication device coordinating with other interference sources that interfere with the sensing process of the second communication device to adjust at least one of the following: signal transmission power, signal transmission time, carrier frequency, or beam angle, or other operations that may reduce interference. Interference cancellation refers to eliminating interference signals in the sensing signal.

[0013] In the first aspect mentioned above, the first communication device can configure one or more first measurement resources for measuring interference signals for the second communication device. In this way, the second communication device can measure communication signals and / or sensing signals that interfere with communication or sensing. Then, based on the interference measurement report, interference management can be effectively carried out, realizing interference measurement and interference management in sensing scenarios or ISAC, thereby improving sensing and / or communication performance.

[0014] In one possible implementation, the method further includes: sending information about a second measurement resource to a second communication device, the second measurement resource being used to measure a useful signal; the second measurement resource corresponding to at least one first measurement resource, the useful signal including a communication signal or a sensing signal.

[0015] In this application, the information of the second measurement resource and the information of at least one first measurement resource can be located in the same resource configuration or report configuration, thus associating the channel measurement resource and the interference measurement resource one by one.

[0016] In this possible implementation, the second measurement resource corresponds to at least one first measurement resource, which is beneficial for calculating the signal and SINR, and can improve the accuracy of SINR calculation and the precision of interference management.

[0017] In one possible implementation, the first or second measurement resource includes any one of the following: channel state information reference signal (CSI-RS) resources, positioning reference signal (PRS) resources, sounding reference signal (SRS) resources, track reference signal (TRS) resources, demodulation reference signal (DMRS) resources, phase track reference signal (PTRS) resources, synchronization signaling block (SSB) resources, or bundled reference signal resources; wherein, the bundled reference signal resources include a combination of at least two resource blocks containing at least one of the following reference signals: CSI-RS, PRS, SRS, TRS, DMRS, PTRS, or SSB.

[0018] In this application, the bundled reference signal can be a combination of the same reference signal on at least two (resource elements, REs), or a combination of different reference signals on at least two REs.

[0019] This possible implementation provides a variety of resources that can be used for interference measurement or useful signal measurement, increasing the flexibility of measuring either interference or useful signals. Furthermore, interference signals can be measured using a reference signal used to measure the communication signal, achieving interference measurement without introducing additional overhead.

[0020] In one possible implementation, the method further includes: receiving at least one interference information sent by the second communication device, wherein the at least one interference information includes interference information between sensing signals, interference information between sensing signals and communication signals, interference information between the communication signals and sensing signals, interference information between the first communication signal and the sensing signal and the second communication signal, or interference information between the communication signal and the first sensing signal and the second sensing signal.

[0021] In this application, at least one interference information may be included in the interference measurement report or may be separate from the interference measurement report.

[0022] This possible implementation provides multiple types of interference information, allowing the first communication device to perform interference management based on different types of interference information, thereby improving the accuracy of interference management.

[0023] In one possible implementation, the interference information includes at least one of the following: the total power of the interference signal, the power corresponding to each resource unit, the phase corresponding to the interference signal, and the time delay corresponding to the interference signal.

[0024] In this application, the total power of the interference signal can be the sum of the power corresponding to each resource unit used for interference measurement.

[0025] In this possible implementation, the interference information includes multiple measurement information related to the interference signal, which is beneficial for more accurate interference management.

[0026] In one possible implementation, the second measurement resource and at least one first measurement resource are used to determine at least one signal-to-interference-plus-noise ratio (SINR) of the useful signal and the interference and noise signals. The at least one SINR includes at least one of the following: a signal-to-interference-plus-noise ratio of the sensed signal to the sensed signal (SS-SINR), a signal-to-interference-plus-noise ratio of the sensed signal to the communication signal (SC-SINR), a signal-to-interference-plus-noise ratio of the communication signal to the sensed signal (CS-SINR), an interference-plus-noise ratio of the first communication signal and the sensed signal to the second communication signal (CS-C-SINR), or an interference-plus-noise ratio of the communication signal and the first sensed signal to the second sensed signal (CS-S-SINR).

[0027] In this application, Among them, P signal P represents the total power of the useful signal. interference P represents the total power of the interference signal. noise This represents the total power of the noise signal.

[0028] In this application, P can be measured using at least one first measuring resource. interference P can be measured through the second measurement resource.signal P noise The value of P can be determined based on the receiver device level and the effective bandwidth of operation, or it can be determined based on the noise measurement results. noise .

[0029] In this possible implementation, at least one SINR may include at least one of SS-SINR, SC-SINR, CS-SINR, CS-C-SINR, or CS-S-SINR, which enriches the types of SINR. The first communication device can perform interference management based on different types of SINR, which can improve the accuracy of interference management.

[0030] In one possible implementation, the method further includes: sending first indication information to a second communication device, the first indication information being used to indicate the measurement quantity of the interference measurement, the measurement quantity including at least one of the following parameters: RSRP, RSSI, SINR, multi-path channel (MPC), point cloud, range angle velocity (RAV) spectrum, channel information, or radio frequency map (RF map); correspondingly, the interference measurement report also includes the measured value of the measurement quantity or the mapping value based on the measurement quantity.

[0031] In this application, the mapping value based on the measurement value refers to the value calculated based on the measurement value. Such as: channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), layer indicator (LI), L1-RSRP or CSI-RS resource indicator (CRI), etc.

[0032] In this possible implementation, the first communication device can also indicate the measured quantity of the interference measurement through the first indication information. In this way, the interference measurement report will report the measured value of the corresponding quantity or the mapping value based on the quantity. The variety of measured quantities can improve the accuracy of interference management.

[0033] In one possible implementation, the method further includes: receiving capability information sent by a second communication device, the capability information including whether interference measurement is supported using at least one of PRS, SRS, TRS, DMRS, PTRS, SSB or bundled reference signals.

[0034] In this possible implementation, the interaction capability information between the first communication device and the second communication device can enable the first communication device to know the type of reference signal supported by the second communication device. Therefore, when configuring the first measurement resources, the resource configuration for interference measurement can be performed according to the capabilities of the first communication device, thereby improving the accuracy of resource configuration.

[0035] In one possible implementation, the first measurement resource is a non-zero power channel state information reference signal (NZP-CSI-RS) resource. The method further includes: transmitting a first reference signal for interference measurement, or transmitting second indication information to a third communication device, the second indication information being used to instruct the third communication device to transmit a second reference signal for interference measurement.

[0036] In this possible implementation, if the first measurement resource is an NZP-CSI-RS resource, indicating a scenario with a known interference source, the first communication device can send a first reference signal to the second communication device. This allows the second communication device to distinguish between interference signals and useful signals by transmitting a first reference signal with a known resource distribution. Alternatively, the first communication device can send a second indication message to a third communication device, which is the interference source. This second indication message instructs the third communication device to send a second reference signal to further distinguish between interference signals and useful signals. This improves the accuracy of interference measurements in scenarios with known interference sources.

The method includes: receiving information from at least one first measurement resource, the at least one first measurement resource being used to measure interference signals, the interference signals including communication signals and / or sensing signals; and sending an interference measurement report, the interference measurement report being used for interference management.

[0038] In the second aspect described above, the second communication device can perform interference measurement based on one or more first measurement resources configured by the first communication device for measuring interference signals. In this way, the second communication device can measure communication signals and / or sensing signals that interfere with communication or sensing, and then effectively manage interference based on the interference measurement report. This enables interference measurement and management in sensing scenarios or ISACs.

[0103] 7. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects.

[0104] 8. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly via the air interface or sending indirectly via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY via the air interface or receiving indirectly from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0105] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0106] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0107] 9. In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (hereinafter referred to as instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed; for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0108] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and the various methods / designs / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various methods / designs / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various methods / designs / implementations within each embodiment can be combined to form new embodiments, methods, or implementations based on their inherent logical relationships. The following descriptions of the embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0109] The sensing method provided in this application can be applied to either a single sensing scenario or a joint sensing scenario. A single sensing scenario refers to a scenario where a single sensing node obtains the required sensing result after sensing. A joint sensing scenario refers to a scenario where multiple sensing nodes sense the same sensing area, and then each sensing node sends its own determined sensing result to a central node, which then fuses the multiple sensing results to reduce sensing uncertainty and improve sensing performance.

[0110] The individual or joint sensing scenarios involved in the embodiments of this application can be single-base sensing scenarios, dual-base sensing scenarios, or hybrid single-base and dual-base sensing scenarios. A dual-base sensing scenario refers to a sensing scenario where the transmitter of the sensing signal and the receiver of the echo signal are not the same communication device. A single-base sensing scenario refers to a sensing scenario where the transmitter of the sensing signal and the receiver of the echo signal belong to the same communication device; a single-base sensing scenario can also be called a self-sensing scenario. A hybrid dual-base and single-base sensing scenario refers to a sensing scenario in which the participating communication devices include both integrated transceiver communication devices and separate transceiver communication devices.

[0111] The dual-base sensing scenario can be understood by referring to Figure 1A. As shown in Figure 1A, this dual-base sensing scenario includes two transmitters, four receivers, and multiple target objects. The two transmitters are transmitter Tx101 and transmitter Tx102; the four receivers are receivers Rx103, Rx104, Rx105, and Rx106, and a central node 107; the target objects can be various types of buildings or other objects. The central node 107 can configure transmission parameters for one or more transmitters, and it can also configure reception parameters for one or more receivers. The central node 107 can also aggregate the sensing results from multiple receivers. The scenario shown in Figure 1A may also include an interference device, which can interfere with the sensing process of receivers Rx105 and Rx106. The central node 107 can also send information on measurement resources for interference measurement to receivers Rx105 or Rx106, so that receivers Rx105 or Rx106 can use the corresponding measurement resources to perform interference measurement. The central node 107 can also coordinate interference with the interference device, or perform interference management such as interference cancellation on the interference information in the sensing results.

[0112] The transmitter Tx101 transmits a sensing signal SS1, and the echo signal ES1 generated by SS1 after passing through the building is received by the receiver Rx103.

[0113] Transmitter Tx102 transmits SS2, and ES2 generated by SS2 passing through a building is received by receiver Rx103; Transmitter Tx102 transmits SS3, and ES3 generated by SS3 passing through a building is received by receiver Rx104; Transmitter Tx102 transmits SS4, and ES4 generated by SS4 passing through a building is received by receiver Rx105; ES5 generated by SS4 passing through a building is received by receiver Rx106.

[0114] It should be noted that SS2, SS3, and SS4 can be sensing signals emitted from the same transmitting beam. However, sensing signals within the range of this transmitting beam will produce echo signals in different directions when encountering buildings at different locations, such as ES2, ES3, ES4, and ES5. Echo signals in different directions can be received by different receiving terminals. Of course, SS2, SS3, and SS4 can also be sensing signals in different beams of the transmitting terminal Tx102.

[0115] In a dual-base sensing scenario, echo signals generated by sensing signals transmitted from the same transmitter can be received by different receivers. For example, ES2 is received by receiver Rx103, ES3 by receiver Rx104, ES4 by receiver Rx105, and ES5 by receiver Rx106. Echo signals generated by sensing signals transmitted from different transmitters can also be received by the same receiver, such as ES1 and ES2 being received by receiver Rx103. Of course, echo signals generated by sensing signals transmitted from the same transmitter can also be received by the same receiver. This application does not limit the correspondence between transmitters and receivers; it is related to the number of transmitters or receivers within a certain area. In either case, the receiver can determine the sensing result based on its received echo signals. Alternatively, the receiver can transmit relevant data from the received echo signals to other communication devices for them to determine the sensing result.

[0116] The single-base sensing scenario can be understood by referring to Figure 1B. As shown in Figure 1B, this single-base sensing scenario may include a central node 107, sensing nodes 108, and multiple target objects. Sensing node 108 includes a transmitter of sensing signals and a receiver of echo signals. The central node 107 can configure the transmission and reception parameters for sensing node 108. The scenario shown in Figure 1B may also include an interference device, which can interfere with the sensing process of sensing node 108. The central node 107 can also send information about measurement resources for interference measurement to sensing node 108, facilitating the sensing node 108 to use the corresponding measurement resources for interference measurement. The central node 107 can also coordinate interference with the interference device or perform interference management such as interference cancellation on the interference information in the sensing results.

[0117] It should be noted that the single-base sensing scenario can include multiple sensing nodes, not limited to the one shown in Figure 1B. When there are multiple sensing nodes, the central node 107 can also summarize the sensing results of multiple sensing nodes.

[0118] When sensing node 108 measures targets in the environment, it can emit one or more beams. The sensing signals SS on the one or more beams can detect targets at different locations. The sensing node then receives the corresponding echo signals ES, and can determine the sensing result based on the ES. Of course, sensing node 108 can also send relevant data from the received echo signals to other communication devices, which can then determine the sensing result.

[0119] In the scenarios described in Figures 1A and 1B above, the central node 107 can also be called a sensing function (SF) network element or a sensing management function (SMF) network element, etc.

[0120] In the scenarios described in Figures 1A and 1B above, the receiver, transmitter, and sensing node can all be terminal devices or network devices, and the central node can also be a terminal device or a network device. The receiver, transmitter, sensing node, and central node shown in Figures 1A and 1B are not limited to their specific forms.

[0121] In addition, the hybrid single-base and dual-base sensing scenario refers to a sensing scenario that includes both the sensing process of the transmitter and receiver as shown in Figure 1A, and the sensing node as shown in Figure 1B.

[0122] The terminal equipment and network equipment of this application are described below.

[0123] Terminal equipment: can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connectivity, or other processing device connected to a wireless modem.

[0124] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be called subscriber unit, subscriber station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc.

[0125] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0126] Terminal devices can also be drones, robots, terminals in device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in telemedicine or telehealth services, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.

[0127] Furthermore, terminal devices can also be terminal devices in future communication systems beyond the fifth generation (5G) (such as 5G Advanced communication systems) or in future evolved public land mobile networks (PLMNs). For example, 5G Advanced networks can further expand the form and function of 5G communication terminals; 5G Advanced terminals include, but are not limited to, vehicles, cellular network terminals (integrating satellite terminal functions), drones, and Internet of Things (IoT) devices.

[0128] In this embodiment, the terminal device can also obtain artificial intelligence (AI) services provided by the network device. Optionally, the terminal device can also have AI processing capabilities.

[0129] Network equipment: This can be equipment within a wireless network. For example, network equipment can be a RAN node (or device) that connects terminal devices to the wireless network, and can also be called a base station. Currently, some examples of RAN equipment include: base stations, evolved NodeBs (eNodeBs), gNBs (gNodeBs) in 5G communication systems, transmission reception points (TRPs), evolved Node Bs (eNBs), radio network controllers (RNCs), Node Bs (NBs), home base stations (e.g., home evolved Node Bs, or home Node Bs (HNBs), base band units (BBUs) or wireless fidelity (Wi-Fi) access points (APs), satellites, drones, unmanned spacecraft, communication balloons, and other non-ground equipment. Additionally, in a network architecture, network equipment can include central unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment that includes both CU and DU nodes.

[0130] Optionally, the RAN node can also be a macro base station, micro base station, indoor station, relay node, donor node, or a radio controller in a cloud radio access network (CRAN) scenario. The RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0131] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be configured separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), radio heads (RHs), or remote radio heads (RRHs).

[0132] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0133] Communication between access network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0134] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0135] Table 1

[0136] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or device form used in the network device. For ease of description, the embodiments of this application are not limited.

[0137] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN gateway or P-GW) in 4th generation (4G) networks; and access and mobility management function (AMF), user plane function (UPF), or session management function (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0138] In this embodiment of the application, the network device may also have network nodes with AI capabilities, which can provide AI services to terminal devices or other network devices. For example, it may be an AI node, computing power node, RAN node with AI capabilities, core network element with AI capabilities, etc. on the network side (access network or core network).

[0139] In this embodiment of the application, the network device can also be a network node with sensing capabilities, which can provide sensing services for terminal devices or other network devices. The network node can sense the sensing target by transmitting sensing signals or receiving echo signals.

[0140] The structure of an ORAN system with sensing capabilities can be understood by referring to Figure 1C. As shown in Figure 1C, the ORAN system may include terminal equipment, access network equipment, core network equipment, and operations administration and maintenance (OAM) equipment. Terminal equipment communicates with access network equipment via air interface. Figure 1C illustrates that access network equipment includes CU and DU, which communicate with each other via the F1 interface. Access network equipment and core network equipment communicate via the NG interface. Access network equipment or core network equipment can also communicate with OAM equipment via the NG interface.

[0141] In this application, one or more of the following devices—core network equipment, access network equipment, terminal equipment, or OAM equipment—may be equipped with one or more sensing modules. Similarly, one or more sensing modules may be installed in the CU or DU within the access network equipment. Optionally, the CU may be further divided into CU-CP and CU-UP. One or more sensing modules may be installed in each of the CU-CP and / or CU-UP. The sensing modules are used to implement corresponding sensing functions. The sensing modules deployed in different network elements may be the same or different.

[0142] As shown in Figure 1C, the sensing module in the ORAN system can perform sensing functions. During the sensing process, the receiving end may receive not only the echo signal of the sensing signal, but also interference from other communication signals or sensing signals in the environment, which may affect the sensing performance. Therefore, if interference can be measured and managed, the sensing performance can be improved. Currently, some interference measurements related to communication tasks are defined in communication scenarios, such as channel state information interference measurement (CSI-IM) or non-zero power channel state information reference signal (NZP-CSI-RS) interference measurement. These interference measurement processes lack support for interference measurement in sensing or ISAC scenarios. This makes it difficult for communication systems to perform effective interference measurement and management when performing sensing or integrated sensing tasks, limiting the performance of communication systems in complex sensing and communication intertwined environments.

[0143] Based on this, embodiments of this application provide a communication method for interference measurement in sensing or ISAC scenarios, thereby effectively managing interference and improving sensing performance. The communication method provided in this application is described below from the perspective of a first communication device and a second communication device. The first communication device can refer to the device itself, or a component within the device responsible for communication and / or sensing functions (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first communication device. The circuit or chip responsible for communication and / or sensing functions can be a modem chip (also known as a baseband chip), or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip. The device can be a network device or a terminal device, and the network device can include access network equipment or core network equipment. The second communication device can refer to the device itself, or a component within the device responsible for communication and / or sensing functions (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the second communication device. The circuits or chips responsible for communication and / or sensing functions may be modem chips (also known as baseband chips), or system-on-a-chip (SoC) or system-in-package (SoC) containing a modem core. This device can be an access network device or a terminal device.

[0144] The first communication device can be a central node, a sensing function (SF) network element, or a sensing management function (SMF) network element. The central node can be a node that configures sensing parameters for the transmitting or receiving end of the sensing signal, and / or a node that summarizes the sensing results. This central node can be a network device or a chip within a network device; of course, it can also be other types of devices. The SF network element / SMF network element can be a node used for sensing function management, or a node that performs all or part of the sensing functions. The function and form of this SF network element / SMF network element can be the same as or similar to the central node. The transmitting end is also called a transmitting node, and the receiving end is also called a receiving node. A transmitting node refers to a node used to transmit sensing signals, and a receiving node refers to a node used to receive the echo signals of the sensing signals.

[0145] The second communication device can be a device corresponding to a receiving node or a sensing node; where a sensing node refers to a node that integrates the transmitting end of sensing signals and the receiving end of echo signals.

[0146] As shown in Figure 2, the communication method provided in this application embodiment includes:

[0147] S201. The first communication device sends information about at least one first measurement resource to the second communication device. Correspondingly, the second communication device receives information about at least one first measurement resource.

[0148] In this application, at least one first measurement resource is used to measure interference signals, which include communication signals and / or sensing signals.

[0149] In this application, the information of the first measurement resource is used to indicate a resource for measuring interfering signals that interfere with sensing or communication signals. The first measurement resource can measure interfering signals, and there can be one or more interfering signals. The information of the first measurement resource can be sent separately or included in resource configuration or report configuration.

[0150] In this application, the information of the first measurement resource may be an index or identifier used to indicate the first measurement resource, such as the identifier of the subcarrier, the identifier of the time domain symbol in the time slot, etc.

[0151] S202. The second communication device performs interference measurement based on at least one first measurement resource and obtains an interference measurement report.

[0152] In this application, the interference measurement report may include multiple pieces of information obtained through interference measurement, such as: channel state information reference signal received power (CSI-RSRP), channel state information received signal strength indication (CSI-RSSI), channel state information signal to interference plus noise ratio (CSI-SINR), sensing reference signal reference signal received power (sensing RS-RSRP), and cross link interference received signal strength indication (CLI-RSSI), etc.

[0153] S203. The second communication device sends an interference measurement report. Correspondingly, the first communication device receives the interference measurement report.

[0154] S204. The first communication device performs interference management based on the interference measurement report.

[0155] In this application, interference management may include interference coordination or interference cancellation. Interference coordination refers to the first communication device coordinating with other interference sources that interfere with the sensing process of the second communication device to adjust at least one of the following: signal transmission power, signal transmission time, carrier frequency, or beam angle, or other operations that may reduce interference. Interference cancellation refers to eliminating interference signals in the sensing signal.

[0156] In the solution provided in this application embodiment, the first communication device can configure one or more first measurement resources for measuring interference signals for the second communication device. In this way, the second communication device can measure communication signals and / or sensing signals that interfere with communication or sensing. Then, based on the interference measurement report, interference management can be effectively carried out, realizing interference measurement and interference management in sensing scenarios or ISAC, thereby improving sensing and / or communication performance.

[0157] The solution provided in this application embodiment can configure not only a first measurement resource for interference measurement, but also a second measurement resource for measuring useful signals. For example, S205 can be included after S201. It should be noted that the information of the second measurement resource and the information of at least one first measurement resource can be located in the same resource configuration or report configuration and sent together, without distinguishing the order. Figure 2 is only used as an example of a separate case and should not be construed as a limitation on the order of sending the first and second measurement resources.

[0158] S205. The first communication device sends information about the second measurement resource to the second communication device. Correspondingly, the second communication device receives the information about the second measurement resource.

[0159] In this application, the information of the second measurement resource may be an index or identifier used to indicate the second measurement resource, such as the identifier of the subcarrier, the identifier of the time domain symbol in the time slot, etc.

[0160] In this application, the second measurement resource is used to measure a useful signal; the second measurement resource corresponds to at least one first measurement resource, and the useful signal includes a communication signal or a sensing signal.

[0161] The second measurement resource corresponds to at least one first measurement resource, which is beneficial for calculating the signal and SINR, improving the accuracy of SINR calculation and the precision of interference management.

[0162] The first or second measurement resource mentioned above includes any one of the following:

[0163] Resources for channel state information reference signal (CSI-RS);

[0164] Resources for positioning reference signal (PRS);

[0165] Resources for sounding reference signals (SRS);

[0166] Resources for tracking reference signals (TRS);

[0167] Resources for the demodulation reference signal (DMRS);

[0168] Resources for phase track reference signal (PTRS);

[0169] Resources of the synchronization signaling block (SSB);

[0170] Resources of bundled reference signals (RS); wherein the resources of bundled reference signals include a combination of at least two resources containing at least one of the following reference signals: CSI-RS, PRS, SRS, TRS, DMRS, PTRS, or SSB.

[0171] Taking the first measurement resource as an example, the different RSs mentioned above used for interference measurement can be indicated by adding a Resource Type in the Resource Configuration or Report Configuration. The newly added Resource Type information element content can include:

[0172] PRS-ResourcesForInterference;

[0173] SRS-ResourcesForInterferenc;

[0174] TRS-ResourcesForInterferenc;

[0175] DMRS-ResourcesForInterferenc;

[0176] PTRS-ResourcesForInterferenc;

[0177] SSB-ResourcesForInterferenc;

[0178] Bunlded RS-ResourcesForInterferenc:SSB+CSI-RS / SSB+PRS….

[0179] The bundled reference signal can be a combination of the same reference signal on at least two resource elements (REs), or a combination of different reference signals on at least two REs. Refer to Figures 3A or 3B for an understanding of bundled reference signals.

[0180] As shown in Figure 3A, one resource block (RB) includes 14 time-domain symbols and 12 subcarriers. Therefore, this RB includes 14 * 12 = 168 resource elements (REs). Taking the bundled reference signal containing a reference signal PRS as an example, if the PRS is carried on the three REs formed by subcarrier 3 and time-domain symbols 3, 5, and 7 shown in Figure 3A, then the PRS on these three REs is a bundled RS, and these three REs are resources of the bundled RS.

[0181] As shown in Figure 3B, taking a bundled reference signal containing multiple reference signals as an example, such as PRS, SRS and TRS, the PRS is carried on the RE formed by subcarrier 3 and time domain symbol 3 as shown in Figure 3B, the SRS is carried on the RE formed by subcarrier 3 and time domain symbol 5, and the TRS is carried on the RE formed by subcarrier 3 and time domain symbol 7. The PRS, SRS and TRS on these three REs are bundled RS, and these three REs are resources of bundled RS.

[0182] Figures 3A and 3B only use PRS, SRS and TRS as examples for illustration. In reality, the bundled reference signal can include a combination of any of the above reference signals on multiple REs.

[0183] As described above, the embodiments of this application provide a variety of resources that can be used for interference measurement or useful signal measurement, improving the flexibility of measuring interference signals or useful signals. Furthermore, interference signals can be measured using a reference signal used to measure communication signals, achieving interference measurement without introducing additional overhead.

[0184] The information regarding at least one first measurement resource and the information regarding the second measurement resource may correspond to the need to associate the channel measurement resource and the interference measurement resource one-to-one in CSI-ReportConfig, that is:

[0185] It should be noted that, in actual configuration, either nzp-CSI-RS-ResourcesForInterference CSI-ResourceConfigId or csi-IM-ResourcesForInterference CSI-ResourceConfigId is selected, and it is not necessary to configure both. nzp-CSI-RS-ResourcesForInterference CSI-ResourceConfigId can be used for scenarios with known interference sources, while csi-IM-ResourcesForInterference CSI-ResourceConfigId can be used for scenarios with unknown interference sources.

[0186] Furthermore, the CSI-RS in the channel measurement or interference measurement examples above are just examples; in reality, they can all be replaced with other possible reference signals, such as: PRS, SRS, TRS, DMRS, PTRS, SSB, or bundled RS.

[0187] In the ISAC scenario, interference between sensing signals may be involved, as well as interference between sensing signals and communication signals, interference between communication signals and sensing signals, and interference between communication signals and the first sensing signal and the second sensing signal.

[0188] Depending on the situation, the information for the first and second measurement resources in ReportConfig will differ. Several examples are given below to illustrate this.

[0189] Example 1. Interference between sensing signals;

[0190] Example 1 illustrates the use of PRS measurement as one sensing signal as the useful signal and PRS measurement as another sensing signal as the interference signal. In practice, the PRS used for sensing measurement or interference measurement can be replaced by any one of CSI-RS, SRS, TRS, DMRS, PTRS, SSB, or bundled RS.

[0191] Example 2. Interference of sensing signals on communication signals;

[0192] Example 2 illustrates the use of CSI-RS to measure communication signals (useful signals) and PRS to measure sensed signals (interference signals). In practice, CSI-RS for channel measurement or PRS for interference measurement can be replaced by any one of CSI-RS, PRS, SRS, TRS, DMRS, PTRS, SSB, or bundled RS.

[0193] Example 3. Interference information of communication signals on sensing signals;

[0194] It can also be written as:

[0205] With the above configuration, the second communication device can measure at least one interference information. This interference information includes interference between sensing signals, interference between sensing signals and communication signals, interference between communication signals and sensing signals, interference between the first communication signal and the sensing signal and the second communication signal, or interference between the communication signal and the first sensing signal and the second sensing signal. This interference information can be included in an interference measurement report sent to the first communication device, or it can be sent to the first communication device independently of the interference measurement report.

[0206] The aforementioned interference information may include at least one of the following: the total power of the interference signal, the power corresponding to each resource unit, the phase of the interference signal, and the time delay of the interference signal. The total power of the interference signal may be the sum of the power corresponding to each resource unit used for interference measurement.

[0207] The correspondence between the second measurement resource and at least one first measurement resource shown in Examples 1 to 4 above is beneficial for determining at least one SINR of the useful signal and the interference and noise signals. The at least one SINR includes at least one of the following: the signal-to-interference-plus-noise ratio (SS-SINR) of the sensing signal to the sensing signal, the signal-to-interference-plus-noise ratio (SC-SINR) of the sensing signal to the communication signal, the signal-to-interference-plus-noise ratio (CS-SINR) of the communication signal to the sensing signal, the interference-noise ratio (CS-C-SINR) of the first communication signal and the sensing signal to the second communication signal, or the interference-noise ratio (CS-S-SINR) of the communication signal and the first sensing signal to the second sensing signal.

In this way, the first communication device can perform interference management based on different types of SINR, which can improve the accuracy of interference management.

[0211] In this embodiment, the aforementioned reportconfig may further include first indication information, which indicates the measurement quantity of the interference measurement. This first indication information can be represented by a Report Quantity, which indicates the measurement quantity reported in the interference measurement report. The measurement quantity includes at least one of the following parameters: RSRP, RSSI, SINR, multi-path channel (MPC), point cloud, range angle velocity (RAV) spectrum, channel information, or radio frequency map (RF map). Correspondingly, the interference measurement report also includes the measured value of the measurement quantity or a mapping value based on the measurement quantity.

[0212] Among them, the measurements related to MPC can include: time delay, range, time offset, Doppler, velocity, and angle for each path, such as angle of arrival (AoA), angle of departure (AoD), zenith of arrival (ZOA), zenith of departure (ZOD), and phase.

[0213] Point cloud-related measurements can include: the position (x, y, z) of points in the point cloud or... Point intensity or power, phase, doppler, or velocity, etc.

[0214] Measurements related to the RAV spectrum may include range velocity map (RV map), range doppler map (RD map), range angle map (RA map), angle velocity map (AV map), angle doppler map (AD map), or information on strong points in the spectrum, the average value of the spectrum, peak side lobe ratio (PSLR), integrated side lobe level ratio (ISLR), etc.

[0215] The measurements of channel information may include: the total power of the interference signal, the power corresponding to each RE, the phase of the interference signal, and the time delay.

[0216] The measurements of an RF map can include T RF-map elements, where T ≥ 1. RF map elements can have various representations, such as ray tracing or multipath information, beamforming information, channel quality indication (CQI), RSSI, power spectral density (PSD), channel H information, etc.

[0217] Each RF mapping element can include ray tracing or multipath information. For example, each path / ray can include information about the path / ray's amplitude, delay, angle, etc. It can also include one or more paths / rays, such as a set of {amplitude, delay, angle...} etc.

[0218] In this application, the mapping value based on the measurement value refers to the value calculated based on the measurement value. Such as: channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), layer indicator (LI), L1-RSRP or CSI-RS resource indicator (CRI), etc.

[0219] The communication method provided in this application embodiment can be applied to the dual-base sensing scenario shown in Figure 1A, and can also be applied to the single-base sensing scenario shown in Figure 1B, which will be described below.

[0220] As shown in Figure 4, in a dual-base sensing scenario, the central node, SF, or SMF network element is a base station (which can be referred to as base station 1). If the central node, SF, or SMF network element is a core network device, the information sent by the core network device can be forwarded through the base station. The receiving node of the echo signal corresponding to the sensing signal is also the node for interference measurement, which is the terminal device (mobile phone) in Figure 4; the interference device (interference source) is the base station (which can be referred to as base station 2) or the UE (vehicle). The transmitting node of the sensing signal can coincide with or not coincide with the central node, SF, or SMF network element (Figure 4 illustrates this with an example of coincidence), and the sensing target is a moving target (drone).

[0221] As shown in Figure 4, the communication method provided in this application embodiment includes:

[0222] S401. The receiving node sends capability information to the central node / SF network element / SMF network element. Correspondingly, the central node / SF network element / SMF network element receives the capability information.

[0223] The capability information includes whether it supports interference measurement using at least one of the following reference signals: PRS, SRS, TRS, DMRS, PTRS, SSB, or bundled reference signals.

[0224] If the capability information indicates that the receiving node supports interference measurement using at least one of the following reference signals: PRS, SRS, TRS, DMRS, PTRS, SSB, or bundled reference signals, then S402 is executed.

[0225] S402. The central node / SF network element / SMF network element sends resource configuration information to the receiving node. Correspondingly, the receiving node receives the resource configuration information.

[0226] The resource configuration information includes at least one first measurement resource, and may also include information on a second measurement resource, or may include first indication information.

[0227] Information regarding the first measurement resource, the second measurement resource, and the first indication information can be found in the preceding descriptions. This resource configuration information can be the reportconfig described earlier.

[0228] S403. The receiving node performs interference measurement based on the resource configuration information.

[0229] This step can measure one or more of the following parameters: SINR (mentioned earlier), MPC-related measurements, point cloud-related measurements, RAV spectrum-related measurements, channel information measurements, or RF map measurements. It can also calculate the mapping value of the measurement value based on the measurement value.

[0230] S404. The receiving node determines whether the measurement results meet the reporting conditions. If they do, then proceed to S405.

[0231] Reporting only when the reporting conditions are met can reduce invalid reports and save on unnecessary reporting costs.

[0232] The reporting conditions can be that some interference measurement parameters meet preset thresholds, such as SINR being greater than the corresponding threshold value.

[0233] S405. The receiving node sends an interference measurement report to the central node / SF network element / SMF network element. Correspondingly, the central node / SF network element / SMF network element receives the interference measurement report.

[0234] Interference measurement reports can include various measured quantities or mapping values ​​of measured quantities.

[0235] S406. The central node / SF network element / SMF network element performs interference management based on the interference measurement report.

[0236] The processes S401 to S406 described above can be used for measuring unknown interference sources, and interference measurements can be performed using CSI-IM-Resources. If the above scenario involves a known interference source, it may also include S407, or S408 and S409.

[0237] S407. The central node / SF network element / SMF network element sends the first reference signal.

[0238] The first reference signal is a reference signal with a known resource distribution. In this embodiment, transmitting a first reference signal with a known resource distribution can help the receiving node distinguish between interference signals and useful signals. This improves the accuracy of interference measurement in scenarios with known interference sources.

[0239] S408. The central node / SF network element / SMF network element sends a second indication message to the base station or UE that is the interference source. Correspondingly, the base station or UE receives the second indication message.

[0240] The second indication information is used to instruct the base station or UE to send a second reference signal for interference measurement.

[0241] S409. The base station or UE sends a second reference signal to the receiving node. Correspondingly, the receiving node receives the second reference signal.

[0242] The central node / SF network element / SMF network element can instruct the interference source to send a second reference signal through second indication information to help the receiving node distinguish between interference signals and useful signals. This improves the accuracy of interference measurements in scenarios with known interference sources.

[0243] As shown in Figure 5, in a dual-base sensing scenario, the central node, SF, or SMF network element is a base station (BS). If the central node, SF, or SMF network element is a core network device, the information sent by the core network device can be forwarded through the base station. The receiving node of the echo signal corresponding to the sensing signal is also the node for interference measurement, which is also a BS in Figure 5. In the scenario shown in Figure 5, the central node, SF, or SMF network element is also the receiving node of the echo signal of the sensing signal, all of which are BSs. The transmitting end of the sensing signal is UE1, the interference device (interference source) is UE2, and the sensing target is a moving target (UAV).

[0246] Both UE1's capability information and UE2's capability information can include whether they support interference measurement using at least one of the following reference signals: PRS, SRS, TRS, DMRS, PTRS, SSB, or bundled reference signals.

[0247] Since the central node, SF or SMF network element, and the receiving node are all BS, it is not necessary for the central node, SF or SMF network element to send resource configuration information to the receiving node. However, this scenario involves a known interference source, UE2, so the BS can also send a second indication message to UE2 to instruct UE2 to send a reference signal for directional interference measurement.

[0248] The scenario of the known interference source UE2 can execute S502, or execute S503 and S504.

[0249] S502.UE1 sends a first reference signal to BS. Correspondingly, BS receives the first reference signal.

[0254] S506.BS determines whether the measurement results meet the reporting conditions. If they do, then proceed to S507.

[0255] S507.BS manages interference based on interference measurement reports.

[0256] As shown in Figure 6, in a dual-base sensing scenario, the central node, SF, or SMF network element is the base station (BS). If the central node, SF, or SMF network element is a core network device, the information sent by the core network device can be forwarded through the base station. The receiving node of the echo signal corresponding to the sensing signal is also the node for interference measurement, which is UE1 in Figure 6. The transmitting end of the sensing signal is the BS, the interference device (interference source) is UE2, and the sensing target is a moving target (UAV). Furthermore, this scenario assumes that the interference source UE2 is known.

[0261] The resource configuration information includes at least one first measurement resource, and may also include information on a second measurement resource, or may include first indication information.

[0262] Information regarding the first measurement resource, the second measurement resource, and the first indication information can be found in the preceding descriptions. This resource configuration information can be the reportconfig described earlier.
