[0044] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0045] In the description of this disclosure, unless otherwise stated, the symbol " / " indicates an "or" relationship; for example, A / B can mean A or B. "And / or" in this document merely represents a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: only A, only B, and A and B. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and the terms "first," "second," etc., do not necessarily imply differences.

[0046] It should be noted that in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] Integrated sensing and communication (ISAC) combines communication and sensing capabilities, endowing networks with the ability to both support communication and perceive the physical world. Sensing capabilities primarily focus on wireless signal sensing to perform functions such as positioning, ranging, velocity measurement, imaging, detection, identification, and environmental reconstruction. By transmitting and receiving sensing signals between sensing nodes or within a single sensing node, and analyzing the direct, reflected, scattered, and diffracted signals of the wireless signals, the perception results of the target or environment are obtained. Furthermore, wireless sensing measurements can be combined with radar, cameras, and other sensors to obtain the final perception results.

[0048] Sensing modes include monostatic, bistatic, and multi-static. For example, base station monostatic (single-site sensing), base station A transmitting B receiving (dual-site sensing), base station transmitting terminal receiving, terminal transmitting base station receiving, terminal monostatic, terminal A transmitting B receiving, and multi-static (any combination of the above sensing modes).

[0049] In integrated communication and sensing systems, to support sensing modes where base stations transmit and receive signals independently or terminals transmit and receive signals independently, it is necessary to overcome the limitations of traditional full-duplex technology and improve spectrum efficiency and system flexibility. However, this innovation brings challenges. When uplink and downlink signals are transmitted simultaneously on the same frequency, severe self-interference and cross-interference occur, requiring equipment or network to implement interference suppression and elimination measures. Furthermore, interference problems exist even in other sensing modes, such as the A-transmit, B-receive sensing mode. Moreover, in designs where sensing and communication functions are separated, interference also exists between sensing and communication. Therefore, addressing these interference problems will be a crucial task in advancing integrated communication and sensing systems.

[0050] Interference mainly includes self-interference and cross-interference. The following description, with reference to the attached figures, addresses different types of interference.

[0051] (1) Base station self-interference

[0052] For example, referring to Figure 1, this interference is caused by the base station transmitting and receiving simultaneously on the same frequency. If the sensing signal used is a linear frequency modulated signal, then the transmission and reception are not on the same frequency, mainly due to adjacent channel interference.

[0053] (2) Base station-to-base station interference

[0054] Scenario 1: Interference between sensing and communication.

[0055] Downlink signals / channels transmitted by neighboring stations interfere with uplink signals / channels received by the base station. Sensing signals transmitted by neighboring stations interfere with uplink signals / channels used for communication received by the base station. Communication signals / channels transmitted by neighboring stations interfere with uplink sensing signals received by the base station. For example, referring to Figure 2, sensing signals transmitted by base station 1 interfere with communication signals / channels received by base station 2 from terminals within the same cell.

[0056] Scenario 2: Interference between sensing base stations. Sensing signals transmitted by neighboring stations interfere with the sensing signals measured by the base station. Two self-transmitting and self-receiving base stations interfere with each other, for example, as shown in Figure 3.

[0057] (3) Base station-terminal interference:

[0058] Neighboring stations' downlink signal / channel transmissions can interfere with the terminal's reception of the local station's downlink signal / channel. As shown in Figure 4, to detect drones, the downtilt angle of the sensing base station and the communication base station may differ. The coverage of the communication base station is limited by the scenario (e.g., densely populated urban areas, rural areas), obstructions, and capacity; therefore, the sensing base station's coverage area may be wider than that of the communication base station, leading to greater interference from the sensing base station to terminals covered by neighboring communication base stations. Specifically:

[0059] Scenario 1: Interference between sensing and communication

[0060] As shown in Figure 4, the sensing signals sent by the neighboring station interfere with the terminal's downlink communication signals / channel reception.

[0061] Downlink communication signals / channel interference sent by neighboring stations affect the terminal's downlink sensing signals / channel reception.

[0062] Scenario 2: Interference between sensing nodes

[0063] The sensing signal transmission of a base station interferes with the sensing signal reception of a terminal.

[0064] (4) Terminal-base station interference:

[0065] The uplink signals / channels sent by neighboring terminals interfere with the base station's reception of uplink signals / channels sent by terminals in this cell.

[0066] Scenario 1: Interference between sensing and communication

[0067] The sensing signals transmitted by neighboring terminals interfere with the uplink communication signals / channels received by the base station.

[0068] The uplink communication signals / channels transmitted by neighboring terminals interfere with the uplink sensing signals / channels received by the base station.

[0069] Scenario 2: Interference between sensing nodes

[0070] The uplink sensing signal sent by the neighboring terminal interfered with the base station.

[0071] For example, as shown in Figure 5: Uplink sensing signals sent by terminals within the range of base station 2 interfere with the uplink communication signals / channels received by base station 1.

[0072] (5) Terminal self-interference

[0073] Interference arises when the terminal transmits and receives simultaneously on the same frequency. If the sensing signal used is a linear frequency modulated signal, the transmission and reception will be on different frequencies, mainly due to adjacent channel interference, as shown in Figure 6.

[0074] (6) Terminal-to-terminal interference

[0075] Interference from neighboring terminals' transmissions affects terminal measurements, specifically:

[0076] Scenario 1: Interference between sensing and communication

[0077] The uplink or side-link sensing signals transmitted by neighboring terminals interfere with the downlink or side-link communication signals / channel reception of the terminal.

[0078] The uplink / sidelink communication signals / channels transmitted by neighboring stations interfere with the downlink / sidelink sensing signal reception of the terminal.

[0079] Scenario 2: Interference between perceptions

[0080] The uplink / sideline sensing signal transmission of neighboring terminals interferes with the downlink / sideline sensing signal reception of the terminal.

[0081] For example, as shown in Figure 7, the uplink sensing signal transmission of neighboring UE 2 interferes with the downlink communication signal / channel reception of UE 1.

[0082] The difference between self-interference in full-duplex communication and self-interference in induction:

[0083] Self-interference in full-duplex communication: All components of the self-transmitted signal received in the receiving link belong to self-interference, including components that leak directly from the transmitting antenna to the receiving antenna, as well as components emitted / scattered / diffracted by the environment or target objects.

[0084] Synesthetic self-interference: It aims to eliminate directly leaked components while retaining components reflected / scattered / diffracted by the environment or target.

[0085] In view of this, this disclosure provides a method for handling inductive interference. This method involves acquiring an interference solution to reduce the interference level of a first node on a second node, and then executing the interference solution. In this way, in an integrated inductive and sensory system, adaptable to different interference situations, an effective interference solution can be acquired and executed to achieve interference suppression and elimination, thereby improving the communication performance of the entire network.

[0086] The scenarios to which this disclosure can be applied include, but are not limited to, any of the communication networks shown in Figures 1 to 7 above.

[0087] In this embodiment of the disclosure, the network architecture of the communication network (including but not limited to 3G, 4G, 5G, and future mobile communication networks) may include at least a first node, a second node, and a core network element. The first node is an interference source node or an interference node, and the second node is an interference-affected node.

[0088] In some embodiments, the second node and the core network element can be collectively referred to as the third node.

[0089] It should be understood that, in some examples, the interference source node may include, but is not limited to, at least one of the following: a communication node, a sensing node, or a synergistic sensing node. The interfered node may include, but is not limited to, at least one of the following: a communication node, a sensing node, or a synergistic sensing node.

[0090] A sensing node refers to a wireless sensing node that participates in the transmission or reception of sensing signals. A sensing node includes, but is not limited to, at least one of the following: base station (BS or TRP), terminal (UE), positioning reference unit (PRU), and sensing reference unit (SRU).

[0091] In some embodiments, the sensing signal transmission configuration includes at least one or more of the following: identification information of the sensing reference signal, number of time-domain symbols of the sensing reference signal, period of the sensing reference signal, transmission beam configuration of the sensing reference signal, comb structure size of the sensing reference signal, comb offset of the sensing reference signal, time-domain offset of the sensing reference signal, bandwidth of the sensing reference signal, time-domain position of the sensing reference signal, power configuration information of the sensing reference signal, power configuration parameters of the sensing reference signal (such as P0, alpha, etc.), path loss reference signal type or index, etc. One or more of these parameters can be configured for a specific sensing signal resource or a set of sensing signal resources. For example, the sensing core network sends the transmission configuration of the sensing transmitting node to the sensing receiving node. The transmission configuration of the sensing transmitting node includes the index, beam direction, and power of each sensing signal transmission resource.

[0092] A communication node refers to a wireless communication node that participates in transmitting or receiving communication signals. Communication nodes include, but are not limited to, base stations (BS or TRP), terminals (UE), routers, and relay nodes.

[0093] Integrated sensing nodes include, but are not limited to, base stations and terminals. The function of an integrated sensing node is to transmit or receive integrated sensing signals via a wireless air interface according to configuration requirements. Communication nodes can receive communication signals and process them to acquire communication information. Sensing receivers can receive integrated sensing signals scattered / reflected / diffracted by the sensing target and perform sensing processing to acquire sensing information.

[0094] For example, Figure 8 shows a schematic diagram of the architecture of a communication system provided in an embodiment of this disclosure. As shown in Figure 8, the communication system 10 includes multiple base stations (e.g., base station 21 and base station 22) and multiple terminals (e.g., terminal 31, terminal 32, terminal 33, and terminal 34). The multiple base stations and multiple terminals can be communicatively connected. A base station can provide network services to terminals in one cell, or it can provide network services to terminals in multiple cells simultaneously.

[0095] In some embodiments, the base station is used to receive or transmit communication signals.

[0096] In some embodiments, the base station is used to transmit sensing signals and receive signals after being scattered / reflected / diffracted by the sensing target and perform sensing processing to obtain sensing information.

[0097] In some embodiments, the base station can transmit sensing signals to sense a target, and simultaneously, the base station can receive and process the echo signal from the target to obtain sensing information. Alternatively, the base station can transmit sensing signals to sense a target, and the terminal can process the echo signal from the target to obtain sensing information.

[0098] In some embodiments, the base station may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station in a 5G network, or a base station in a future communication system. The base station may include various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network-side devices such as primary cells and secondary cells.

The term "terminal" can sometimes also refer to a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent, or UE device, etc., but this disclosure does not limit the terminology used in this embodiment.

[0100] It should be noted that Figure 8 is only an exemplary framework diagram. The number of devices included in Figure 8 and the names of each device are not limited. In addition to the devices shown in Figure 8, the communication system may also include other devices, such as core network devices.

[0101] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0102] This disclosure provides a method for handling inductive interference, applied to a first node. As shown in Figure 9, the method includes steps S101-S102.

[0103] S101, The first node obtains an interference solution, which is used to reduce the interference of the first node on the second node.

[0107] In some embodiments, the beam configuration scheme includes at least one of the following: recommended and / or unrecommended beam information; recommended and / or unrecommended beam pairs; and interference measurement reporting for null filtering.

[0108] The beams in this disclosure may include a transmit beam and a receive beam.

[0109] For example, the transmit beam or the receive beam can be changed or adjusted based on recommended and / or not recommended beam information.

[0110] In some embodiments, determining the beam configuration scheme requires different nodes to exchange their beam information. For example, in sensing beam or sensing resource interaction, if interference between sensing and communication is considered, it is necessary to exchange the beam information of sensing and communication.

[0111] In some embodiments, the beam configuration scheme involves the interference source node sending the transmission resource configuration information (including transmission beam configuration information) of the interference source node to the interference recipient node, and the interference recipient node selecting an appropriate receiving beam.

[0112] In some embodiments, the beam configuration scheme involves the interference source node sending resource configuration information to the sensing core network, and the sensing core network recommending a suitable receiving beam for the interfered node.

[0113] In some embodiments, the beam configuration scheme further includes null-beaming, which can maximize the amplification of the useful signal and suppress interference signals. The first node adjusts the beam or the precoding matrix according to the channel conditions to suppress the beam gain in the direction of interference.

[0114] In some embodiments, beam information is bound to at least one of the following parameters: sensing area index, timestamp, receiving beam, receiving quasi-co-location (QCL) resource, transmitting beam, spatial relationship of transmission, resource index of signal, and first indication information; wherein the first indication information is used to indicate whether the beam information is a recommended beam or a non-recommended beam.

[0117] For example, the required signal power can be increased or the power of the interfering signal can be reduced.

[0118] For example, the affected node can increase the power of its transmitted signal as much as possible, or the source node can reduce the power of its transmitted signal to reduce the impact of the interference.

[0119] In some embodiments, the signal includes at least one of the following: uplink sensing signal, uplink communication signal, downlink sensing signal, downlink communication signal, lateral sensing signal, and lateral communication signal.

[0120] S102, First node execution interference solution.

[0121] In some embodiments, the first node receives interference feedback information from the second node, which is used to determine the interference situation of the second node after the first node executes the interference solution.

[0122] For example, interference feedback information includes at least one of the following: whether the interference has been resolved, whether the interference has been mitigated, and the degree to which the interference has been resolved.

[0123] In some embodiments, the first node sends resource configuration information to the third node, where the third node is the second node or a core network element.

[0124] In some embodiments, after executing the interference solution, the first node updates the resource configuration information to obtain the updated resource configuration information; the first node then sends the updated resource configuration information to the third node.

[0125] The updated resource configuration information includes updated transmit signal / channel configurations, and the updated transmit signal / channel configuration parameters may be offset values ​​based on the initial configuration.

[0126] For example, the interference source node can send the updated transmission signal / channel configuration to the sensing core network. The updated transmission signal / channel configuration parameters may be offset values ​​based on the initial configuration.

[0127] In some embodiments, S101 can be implemented as S201.

[0128] S201, Interference solution for the first node receiving data sent by the second node.

[0129] In some embodiments, before receiving the interference solution sent by the second node, the first node obtains the interference measurement report from the second node. The interference measurement report may have other names, such as interference measurement result, interference measurement report, etc. This allows the first node to pre-determine the interference situation experienced by the second node in order to perform subsequent operations.

[0130] In some embodiments, the interference measurement report includes at least one of the following: channel impulse response information, power delay spectrum, delay distribution information, target channel information, interference information of the target path, null space of the interference channel, eigenvectors corresponding to the third preset number of strongest singular values ​​of the interference channel eigenvalue decomposition or a feature space composed of eigenvectors, eigenvectors corresponding to the fourth preset number of weakest singular values ​​of the interference channel eigenvalue decomposition or a feature space composed of eigenvectors, received signal strength indication (RSSI) information, reference signal received power, reference signal received quality, signal-to-noise ratio, signal-to-interference-plus-noise ratio (SNR), reference signal received power of the target path, beam pointing vector, number of time-domain samples for channel interference measurement, number of antenna ports for channel interference measurement, information of the received antenna reference point (ARP), beam precoding matrix, index of interfered resources (e.g., index of interfered sensing signal resources), time information of interference, and index of sensing area.

[0132] In some embodiments, before receiving the interference solution sent by the second node, the first node obtains the interference information of the second node. This allows the first node to pre-determine the interference situation experienced by the second node in order to perform subsequent operations.

[0133] In some embodiments, the first node obtaining interference information from the second node may include at least one of the following: the first node requests interference information from the second node, and the second node sends interference information to the first node; or the first node receives interference information sent by the second node.

[0134] For example, the second node sends the interference information to multiple possible first nodes via unicast, multicast, or broadcast.

[0135] The interference information includes at least one of the following: interference resource index, second indication information, timestamp, time window, received beam, and power of the first node, wherein the second indication information is used to indicate whether the second node is interfered with.

[0136] The index of interfered resources can be at least one of the following: a sensing signal resource index, a sensing signal resource set index, a communication signal resource index, a communication signal resource and index, or a sensing signal resource pool index. Second indication information can be provided via an indicator.

[0137] In some embodiments, the first node sends resource configuration information to the second node. This allows the second node to determine interference solutions based on the resource configuration information, thereby mitigating interference when processing signals.

[0138] The resource configuration information can be transmission resource configuration information within a preset time window or within a preset frequency range. In some embodiments, the resource configuration information may include: transmission period, duration, start time, number of repetitions, frequency start position, bandwidth, sequence number, etc.

[0139] In some embodiments, the second node sends a resource configuration request to the first node, the resource configuration request being used to request the first node's resource configuration information.

[0140] For example, if a first node sends a positioning reference signal, a second node can request the first node to provide the positioning reference signal configuration information.

[0141] In some embodiments, the interference solution received by the first node from the second node includes at least one of the following: a mute configuration scheme; a beam configuration scheme; and a power control scheme.

[0142] The details of each interference solution can be found in the descriptions in the above embodiments, and will not be repeated here.

[0143] For example, as shown in Figure 10, the first node is designated as the interference source node and the second node as the interference-affected node. The method includes at least one of the following operations:

[0150] Operation 7: The affected node sends interference feedback information to the interference source node.

[0151] The descriptions related to operations 1-7 can be found in the above embodiments and will not be repeated here.

[0152] In some embodiments, S101 can be implemented as S301.

[0160] The resource configuration information can be transmission resource configuration information within a preset time window or within a preset frequency range. In some embodiments, the resource configuration information may include: transmission period, duration, start time, number of repetitions, frequency start position, bandwidth, sequence number, etc.

[0161] In some embodiments, a core network element collects resource configuration information of a second node and / or a first node, including: the core network element requests a node to assist in collecting resource configuration information of the second node and / or the first node.

[0162] For example, if the second node and / or the first node are transmitting communication signals and have no direct connection to the sensing core network, the sensing core network can still request a node to assist in collecting the transmission resource configuration information of the second node and / or the first node.

[0163] If the second node and / or the first node sends a positioning reference signal, the sensing core network can request the positioning core network to provide the positioning reference signal configuration information of the second node and / or the first node.

[0164] In some embodiments, the interference solution is determined by the core network elements collecting interference measurement reports from the second node and / or the first node.

[0165] In some embodiments, the interference solution collects interference measurement reports from a second node and / or a first node for the core network element, including: the core network element receiving interference measurement reports sent by the second node and / or the first node; or, the core network element sending interference measurement report request information to the second node and / or the first node, and receiving interference measurement reports sent by the second node and / or the first node.

[0166] Information related to interference measurement reports can be found in the descriptions in the above embodiments, and will not be repeated here.

[0167] In some embodiments, the interference measurement report request information (or signaling) may include one or more of the following: channel impulse response information, power delay spectrum, delay distribution information, target channel information, interference information of the target path, null space of the interference channel, eigenvectors corresponding to the third preset number of strongest singular values ​​of the interference channel eigenvalue decomposition or a feature space composed of eigenvectors, eigenvectors corresponding to the fourth preset number of weakest singular values ​​of the interference channel eigenvalue decomposition or a feature space composed of eigenvectors, signal strength indication information, reference signal received power, reference signal received quality, signal-to-noise ratio, signal-to-interference-plus-noise ratio (SIN / INF / NOT), reference signal received power of the target path, beam pointing vector, number of time-domain samples for channel interference measurement, number of antenna ports for channel interference measurement, information of the receiving antenna reference point, beam precoding matrix, index of interfered resources, time information of interfered events, and index of sensing area.

[0168] In some embodiments, before collecting interference measurement reports from the second node and / or the first node, the core network element may first send interference measurement resource configuration information to the second node and / or the first node so that the second node and / or the first node can measure and obtain interference measurement reports based on the interference measurement resource configuration information.

[0169] Interference measurement resource configuration information may include the signal type and interference measurement signal resources.

[0171] The details of the solutions for each type of interference can be found in the descriptions in the above embodiments, and will not be repeated here.

[0177] Operation 5: The affected node sends interference feedback information to the sensing core network.

[0178] The descriptions related to operations 1-5 can be found in the above embodiments and will not be repeated here.

[0179] In some embodiments, operation S101 can be implemented as S401-S402.

[0180] S401, The first node obtains the interference measurement report from the second node.

[0181] Information related to the interference measurement report can be found in the above description and will not be repeated here.

[0182] In some embodiments, the first node obtains the interference measurement report of the second node, including: the first node obtains the interference measurement report of the second node from the second node or a core network element.

[0183] In some embodiments, the first node obtains the interference measurement report of the second node from the core network element, including: the core network element sending an interference measurement report request message to the second node, the core network element receiving the interference measurement report sent by the second node, and forwarding the interference measurement report to the first node.

[0184] In some embodiments, before the first node obtains the interference measurement report of the second node from the core network element, the method further includes: the first node sending a request message to the core network element, the request message being used to request the core network element to coordinate and resolve the interference problem.

[0185] In some embodiments, the request information includes interference information, which includes at least one of the following: an index of interfered resources, second indication information, a timestamp, a time window, a received beam, and the power of the first node, wherein the second indication information is used to indicate whether the second node is interfered with.

[0186] In some embodiments, before the first node obtains the interference measurement report of the second node from the core network element, the core network element further includes: collecting resource configuration information of the second node and / or the first node.

[0187] In some embodiments, the core network element collects resource configuration information from a second node and / or a first node, including: the core network element sending resource configuration request information to the second node and / or the first node; and the core network element receiving the resource configuration information sent by the second node and / or the first node; or, the second node and / or the first node sending its own resource configuration information to the core network element. The resource configuration request information is used to request the second node and / or the first node to send its own resource configuration information.

[0188] The resource configuration information can be transmission resource configuration information within a preset time window or within a preset frequency range. In some embodiments, the resource configuration information may include: transmission period, duration, start time, number of repetitions, frequency start position, bandwidth, sequence number, etc.

[0189] In some embodiments, before the first node obtains the interference measurement report from the second node from the core network element, the process may further include: the core network element sending interference measurement resource configuration information to the second node, and the second node measuring the interference based on the interference measurement resource configuration information to obtain the interference measurement report.

[0190] In some embodiments, before the first node obtains the interference measurement report from the second node from the core network element, the core network element may further include: sending auxiliary information to the first node, the auxiliary information being used to determine interference measurement resource configuration information.

[0191] Interference measurement resource configuration information includes the signal type and interference measurement signal resources.

[0192] The configuration information for interference measurement resources may include at least one of the following: the index of the interference measurement resource, the starting frequency domain position, the bandwidth, the number of physical resource blocks, the starting position in the time domain, the duration, the period, the number of repetitions, zero-power interference measurement resources, and non-zero-power interference measurement resources.

[0193] In some embodiments, the first node obtains the interference measurement report from the second node, including: the first node receiving the interference measurement report sent by the second node.

[0194] In some embodiments, before the first node receives the interference measurement report sent by the second node, the method further includes: the second node receiving information about the first node sent by a core network element. The information about the first node includes at least one of the following: the index of the first node, the serving base station index of the first node, the sensing signal transmission resource configuration of the first node, the interference measurement resource configuration information of the first node, the time-domain length, time-domain start position, period, repetition count, bandwidth, comb size, comb offset, beam configuration, and power configuration of the interference measurement signal resource / resource set. In this way, the second node can determine the first node from which it needs to receive the interference measurement report.

[0195] In some embodiments, the information of the first node is determined based on at least one of the following: the location information of the second node, the area information where the second node is located, and the information of multiple neighboring areas surrounding the second node.

[0196] For example, the sensing core network determines the distribution information of sensing nodes around the disturbed sensing node as possible interference source nodes, or the sensing core network can learn about the information of possible interference source nodes around the disturbed sensing node through interaction with other core networks (such as the positioning core network).

[0197] S402. The first node determines the interference solution based on the interference measurement report from the second node.

[0198] In some embodiments, the first node adjusts its transmission beam accordingly to minimize the impact on the second node based on the interference measurement report from the second node.

[0199] For example, the interference source node receives an interference measurement report from the interfered node or from the sensing core network. The interference source node can adjust its transmission beam accordingly to minimize the impact on the interfered node.

[0200] For example, if the interference source node is a terminal, the interfered node or the serving base station or sensing core network of the interfered node can send the interference measurement report to the serving base station of the interference source node, and the serving base station can determine how to adjust the transmission configuration.

[0201] For example, taking interference between sensing nodes as an example, as shown in Figure 3, the sensing signals sent by two sensing nodes can interfere with each other. The two sensing nodes need to sense different targets, and the sensing nodes can be base stations or roadside units (RSUs). The two sensing nodes shown in the figure are sensing in a self-transmitting and self-receiving mode; in reality, the sensing nodes may also be in a mode where A transmits and B receives. This interference can be handled by referring to the interference processing flow shown in Figure 12, which includes at least one of the following operations.

[0202] Operation 1: The affected node sends a first request message to the sensing core network. The request message is used to request the sensing core network to coordinate a solution to resolve the interference.

[0203] Operation 2: The sensing core network receives resource configuration information (including signal / channel transmission configuration information) sent by the interference source node.

[0204] Operation 3: The core sensing network sends interference measurement resource configuration information to the affected nodes.

[0205] Operation 4: Measure the interference at the affected node and obtain the interference measurement report.

[0206] Operation 5: The core sensing network sends an interference measurement report request to the affected node.

[0207] Operation 6: The affected node sends an interference measurement report to the sensing core network.

[0208] Operation 7: The core sensing network sends an interference measurement report to the interference source node.

[0209] Operation 8: The interference source node sends the updated resource configuration information to the sensing core network.

[0210] Operations 5, 6, and 7 can be replaced by the sensing core network sending information about possible interference source nodes to the affected nodes, and the affected nodes sending interference measurement reports to the possible interference source nodes.

[0211] The descriptions related to operations 1-8 can be found in the above embodiments and will not be repeated here.

[0212] For example, if the interfered node or the interference source node is a terminal, after receiving the request information from the interfered sensing node, the sensing core network can send auxiliary information to the serving base station of the interfered node. This auxiliary information is used to determine the interference measurement resource configuration information. The sensing core network can provide possible interference source information to the serving base station of the interfered node. The interfered node, its serving base station, or the sensing core network can send an interference measurement report to the serving base station of the interference source node, which will then determine how to adjust the transmission configuration. Possible actions by the terminal performing interference measurement include: the terminal performs measurement if and only if the interference signal to be measured is completely contained within the active bandwidth part (BWP); or if the interference measurement signal and the active BWP partially overlap, the terminal measures the portion of the signal falling within the active BWP. The terminal's interference measurement report can also report the measured bandwidth / frequency domain information (e.g., the frequency domain start position and bandwidth of the measurement result).

[0213] It is understandable that the above describes how the interference source node (first node) determines the interference solution based on the interference measurement report of the interfered node (second node). Due to channel reciprocity, the interference source node (first node) can also measure the channel to obtain the interference measurement report and determine the interference solution based on it. The signaling process involved includes at least one of the following: the sensing core network collects interference information from the interfered node; the sensing core network identifies possible interference source nodes; the sensing core network forwards or partially sends the interference information of the interfered node to the possible interference source node or to the serving base station of the interference source node; the possible interference source node measures the channel conditions to determine the interference measurement report; and the possible interference source node can report the interference measurement report to its serving base station.

[0214] For example, taking interference between sensing nodes and communication nodes as an example, as shown in Figure 13, if the time-division duplex configurations of the two base stations are different, base station 1 transmits sensing signals on the downlink (D) symbol, while base station 2 simultaneously receives sensing signals and the uplink communication signals / channels of the terminal on the uplink (U) symbol. In this case, base station 2 does not need to have full-duplex capability, but there may be interference between the sensing signals transmitted by base station 1 and the communication signals / channels transmitted by the terminal. Furthermore, if the time-division duplex configurations of the two base stations are consistent, it is still possible that due to the timing inconsistency between the two base stations, at a certain moment, one base station transmits downlink interference to the other base station receiving uplink.

[0215] The core network can be used to manage interference in a coordinated manner (such as the sensing core network participating in the management of interference around a certain area).

[0216] For example, if some nodes are only used for communication and do not participate in specific sensing services, the sensing core network can send interference measurement resource configuration information and request these nodes to report interference measurement reports. In other words, the core network can designate some nodes for interference control.

[0217] For example, if some nodes are only used for communication and do not participate in specific sensing services, the sensing core network can request resource configuration information (such as signal / channel transmission configuration, including beamforming) from that node or its serving base station. The sensing core network can then send an interference solution to that node or its serving base station. For example, the interference solution may include recommended / not recommended beamforming information, recommended / not recommended symbol lengths, and recommended / not recommended resource indexes.

[0218] If a node does not have a direct signaling connection to the core network, then nodes need to exchange information, which may include at least one of the following:

[0219] The affected node requests interference measurement resource configuration information from potential interference source nodes in the vicinity; this request signaling can be sent via broadcast, multicast, or unicast. If it is a sidechain-aware node, the affected node may request it via sidechain control information.

[0220] The interference source node sends interference measurement resource configuration information to the interfered node;

[0221] The affected node measures the channel to determine the interference measurement report and sends it to the interference source node.

[0222] Based on this, the first node can obtain and implement effective interference solutions to achieve interference suppression and elimination, thereby improving the communication performance of the entire network.

[0223] This disclosure provides a method for handling inductive interference, applied to a second node. As shown in Figure 14, the method includes steps S501-S502.

[0224] S501, The second node determines the interference solution, which is used to reduce the interference of the first node to the second node.

[0225] In some embodiments, the interference solution includes at least one of the following: a silent configuration scheme; a beam configuration scheme; and a power control scheme.

[0226] In some embodiments, the mute configuration scheme includes at least one of the following: a mute configuration scheme for target sensing signal resources or resource sets; a mute configuration scheme for transmission resources or resource sets within a target time period; a mute configuration scheme for repetitive transmission resources or resource sets; mute configuration information for transmission resources or resource sets over a target period; a mute configuration scheme for target frequency domain resources; a mute configuration scheme for target time domain resources; a mute configuration scheme for transmission resources in the target beam direction; a mute configuration scheme for transmission resources in a target comb structure; and a mute configuration scheme for transmission resources on target symbols.

[0227] A muting configuration scheme can transform signals on transmission resources into zero-power signals. The target frequency domain resource for muting can be a target physical resource block or a target resource element.

[0228] In some embodiments, the beam configuration scheme includes at least one of the following: recommended and / or unrecommended beam information; recommended and / or unrecommended beam pairs; and interference measurement reporting for null filtering.

[0229] The beams in this disclosure may include a transmit beam, a receive beam, or a transmit-receive beam pair.

[0230] For example, the transmit beam or the receive beam can be changed or adjusted based on recommended and / or not recommended beam information.

[0231] In some embodiments, determining the beam configuration scheme requires different nodes to exchange their beam information. For example, in sensing beam or sensing resource interaction, if interference between sensing and communication is considered, it is necessary to exchange the beam information of sensing and communication.

[0232] In some embodiments, the beam configuration scheme involves the interference source node sending the transmission resource configuration information (including transmission beam configuration information) of the interference source node to the interference recipient node, and the interference recipient node selecting an appropriate receiving beam.

[0233] In some embodiments, the beam configuration scheme involves the interference source node sending resource configuration information to the sensing core network, and the sensing core network recommending a suitable receiving beam for the interfered node.

[0234] In some embodiments, the beam configuration scheme further includes null-beaming, which can maximize the amplification of the useful signal and suppress interference signals. The first node adjusts the beam or the precoding matrix according to the channel conditions to suppress the beam gain in the direction of interference.

[0235] In some embodiments, beam information is bound to at least one of the following parameters: sensing area index, timestamp, receiving beam, receiving quasi-co-located resource, transmitting beam, spatial relationship of transmission, resource index of signal, and first indication information; wherein the first indication information is used to indicate whether the beam information is a recommended beam or a non-recommended beam.

[0236] For example, the resource index of a signal includes at least one of the following: a sensing signal resource index, a synchronization signal block (SSB) resource index, a channel state information reference signal (CSI-RS) resource index, a sounding reference signal (SRS) resource index, and a downlink positioning reference signal (DL PRS) resource index.

[0237] In some embodiments, the power control scheme includes at least one of the following: a power adjustment range for the signal; a power adjustment amount for the signal; a resource index for the signal; a configuration index for the signal; timing information; a recommended power range for the signal; a non-recommended power range for the signal; and beam information associated with the signal.

[0238] For example, the required signal power can be increased or the power of the interfering signal can be reduced.

[0239] For example, the affected node can increase the power of its transmitted signal as much as possible, or the source node can reduce the power of its transmitted signal to reduce the impact of the interference.

[0240] In some embodiments, the signal includes at least one of the following: uplink sensing signal, uplink communication signal, downlink sensing signal, downlink communication signal, lateral sensing signal, and lateral communication signal.

[0241] S502, Second Node Interference Solution.

[0242] In some embodiments, the second node sends an interference solution to the first node or a core network element.

[0243] In some embodiments, before the second node sends the interference solution to the first node, the second node receives information about the first node sent by the core network element. The information about the first node includes at least one of the following: the index of the first node, the index of the serving base station of the first node, the configuration of the sensing signal transmission resources of the first node, the configuration of the interference measurement signal resources of the first node, the time domain length, time domain start position, period, number of repetitions, bandwidth, comb structure size, comb structure offset, beam configuration, and power configuration of the interference measurement signal resources / resource set.

[0244] In some embodiments, the information of the first node is determined based on at least one of the following: the location information of the second node, the area information where the second node is located, and the information of multiple neighboring areas surrounding the second node.

[0245] In some embodiments, the second node transmits capability information, which is used to determine at least one of the following: whether null filtering is supported; whether interference measurement reporting is supported; the number of interference measurements that can be reported; the type of interference measurement that can be reported; whether channel impulse response (CIR) is supported and the dimensions of the supported CIR; whether power delay profile (PDP) is supported and the dimensions of the supported PDP; and whether delay distribution is supported. Profile (DP) or supported delay distribution dimension; whether it supports target channel or supports target channel reporting dimension; whether it supports reporting the feature space of the target channel; the strongest first preset number of path interference that can be supported; whether it supports the second preset number of path interference; whether it supports reporting the null space of the interference channel; whether it supports reporting the eigenvectors corresponding to the third preset number of strongest singular values ​​of the interference channel eigenvalue decomposition or the feature space composed of eigenvectors; whether it supports reporting the eigenvectors corresponding to the fourth preset number of weakest singular values ​​of the interference channel eigenvalue decomposition or the feature space composed of eigenvectors; whether it supports reporting the beam pointing vector; whether it supports reporting the beam precoding matrix indicator (PMI); whether it supports recommended or not recommended beam information; the maximum number of recommended beams / beam pairs that can be supported; whether it supports recommended or not recommended power configuration; the number of pre-configured sensing signals that can be supported; the maximum sensing signal power that can be supported; the range of sensing signal power that can be supported; the number of interference measurement resources that can be supported; whether it supports silent part resources.

[0246] The information on recommended or not recommended beams may include at least one of the following: the number of recommended or not recommended uplink beams, the number of recommended or not recommended downlink beams, and the number of recommended or not recommended sidelink beams.

[0247] The maximum supported sensing signal power may also include the supported sensing signal power modification amount or the supported sensing signal power range.

[0248] The number of interference measurement resources that can be supported can include the number of periodic, non-periodic, or semi-persistent interference measurement resources.

[0249] Whether or not resources can be muted can also be referred to as the supported mute mode.

[0250] For example, a sensing node can report one or more capability information to the sensing core network or base station. In this way, the sensing core network or base station can determine the corresponding interference measurement resource information and the corresponding interference solutions based on the one or more capability information reported by the sensing node.

[0251] In some embodiments, S501 can be implemented as follows:

[0252] S601, The second node obtains the resource configuration information of the first node.

[0253] S602, The second node generates an interference solution based on the resource configuration information of the first node.

[0254] Resource configuration information can be transmission resource configuration information within a time window or a certain frequency range. In some embodiments, resource configuration information may include: transmission period, duration, start time, number of repetitions, frequency start position, bandwidth, sequence number, etc.

[0255] In some embodiments, before the second node obtains the resource configuration information of the first node, the method further includes: the second node sending resource configuration request information to the first node, the resource configuration request information being used to request the acquisition of the resource configuration information of the first node.

[0256] For example, if a first node sends a positioning reference signal, a second node can request the first node to provide the positioning reference signal configuration information.

[0257] Other signaling interaction processes involved in this embodiment can be referred to the description in S201.

[0258] In some embodiments, S501 can be implemented as follows:

[0259] S701, The second node obtains the interference solution determined by the first node.

[0260] In some embodiments, before the second node obtains the interference solution determined by the first node, the second node sends its own interference measurement report or forwards it to the first node via a core network element. In this way, the first node or the core network element can determine the interference solution based on the interference measurement report.

[0261] In some embodiments, the second node obtains the interference solution determined by the first node, including: the second node receiving the interference solution sent by the first node, or the second node requesting information from the first node, the requesting information being used to request the first node to send the interference solution.

[0262] The specific signaling interaction process involved in the interference solution determined by the first node can be found in the descriptions in S401-S402.

[0263] In some embodiments, S501 can be implemented as follows:

[0264] S801, the second node obtains the interference solution determined by the core network elements.

[0265] In some embodiments, the second node obtains the interference solution determined by the core network element, including: the second node sending a first request message to the core network element, the first request message being used to request the core network element to determine the interference solution; and the second node receiving the interference solution sent by the core network element.

[0266] In some embodiments, the first request information includes interference information, which includes at least one of the following: an index of interfered resources, second indication information, a timestamp, a time window, a received beam, and the power of the first node, wherein the second indication information is used to indicate whether the second node is interfered with.

[0267] In some embodiments, the second node sends an interference measurement report to the core network element. This allows the core network element to determine an interference solution based on the interference measurement report.

[0268] In some embodiments, before the second node sends its interference measurement report to the core network element, the second node receives interference measurement resource configuration information sent by the core network element. The interference measurement resource configuration information may include at least one of the following: index of the interference measurement resource, starting frequency domain position, bandwidth, number of physical resource blocks, starting time domain position, time length, period, number of repetitions, zero-power interference measurement resource, and non-zero-power interference measurement resource.

[0269] Other signaling interaction processes involved in the interference solutions determined by the core network elements can be found in the description in S301.

[0270] It is understandable that other related content in S501-S502 can also be found in the descriptions in S101-S102.

[0271] Based on this, in the scenario of integrated sensing, the second node can adapt to different interference situations, obtain and execute effective interference solutions to achieve the effect of interference suppression and elimination, thereby improving the communication performance of the entire network.

[0272] The method for determining the above beam configuration scheme is described below:

[0273] In some embodiments, the beam configuration scheme is determined based on beam pairing, which aims to find the optimal beams of interfering nodes and the beams of the interfered nodes to minimize interference between nodes in the spatial domain.

[0274] In some embodiments, determining the beam configuration scheme requires different nodes to exchange their beam information.

[0275] For example, sensing beams or sensing resource interaction; if interference between sensing and communication is considered, it is necessary to interact with the beam information of sensing and communication.

[0276] For example, the interference source node sends its transmission resource configuration information (including beam information) to the interfered node, and the interfered node selects a suitable receiving beam. The interference source node then sends its resource configuration information (including beam information) to the sensing core network, and the sensing core network recommends a suitable receiving beam for the interfered node.

[0277] In some embodiments, the beam configuration scheme is determined through the interaction of recommended or not recommended beam information between different nodes, including at least one of the following:

[0278] The interfered node provides the sensing core network with recommended or unrecommended transmission beam information. "Recommended" can mean recommending the transmission of a certain sensing transmission resource index or targeting a certain interference source node.

[0279] The sensing core network provides recommended or unrecommended transmission beam information to interference source nodes. "Recommended transmission beam information" can refer to a sensing transmission resource index that is recommended for transmission.

[0280] The affected node provides the interference source node with recommended or unrecommended transmission beam information. "Recommended transmission beam information" can mean recommending the transmission of a certain sensing transmission resource index.

[0281] The sensing core network provides recommended or unrecommended receiving beam information to the interfered nodes. The "receiving beam" indicator can be a reference signal index.

[0282] The affected node reports the measurement results of one or more received beams to the sensing core network or the interference source node.

[0283] For example, if the affected node is a terminal, the terminal can provide interference information or an interference measurement report to the base station, which will then resolve the interference. If the interference source is a terminal, the base station can adjust the transmission configuration for the interfering terminal via radio resource control (RRC), media access control element (MAC CE), or downlink control information (DCI). If the interference source is a terminal in a neighboring cell, the base station can notify the neighboring base station of the interference measurement report or recommend / dislike beam information via the Xn interface. If the interference source is another base station, the base station can also notify the neighboring base station of the interference measurement report or recommend / dislike beam information via the Xn interface. Alternatively, the base station can send the interference measurement results or recommended / dislike beam information to the sensing core network, which will then suggest transmission configurations or forward the interference measurement report to the neighboring base station.

[0284] For example, if the interfered node is a terminal, the terminal can also provide interference information, interference measurement reports, or recommended / not recommended beam information to the sensing core network. The sensing core network provides recommended or not recommended beam information to the terminal's serving base station, which is then configured by the serving base station for the terminal.

[0285] For example, considering interference between terminal positioning and communication, such as interference between the terminal's reception of sensing signals from neighboring cells and the terminal's reception of communication signals from the base station, the terminal can send recommended or unrecommended beams to the base station, carried by MAC CE or DCI. Alternatively, the terminal can send recommended or unrecommended beam information to the sensing core network. Unrecommended beams may be associated with significant channel interference, while recommended beams may be from directions with less signal interference.

[0286] For example, taking the interference between the terminal's positioning and sensing as an example, such as interference between the downlink positioning signal received by the terminal from base station 1 and the downlink sensing signal received by the terminal from base station 2. The terminal may send recommended or unrecommended beam information to the base station (including base station 1 or base station 2) or the sensing core network, and the terminal may also send recommended or unrecommended beam information to the positioning core network.

[0287] For example, taking perception involving only the terminal (sidechain perception) as an example, the beam configuration scheme can be determined through one or more of the following interactive recommendations:

[0288] The terminal sends recommended or unrecommended beam information to the sensing core network or to the base station;

[0289] Terminals send recommended or unrecommended beam information to other terminals via sidelink signaling. Recommended or unrecommended beam indicators are added to the sidelink control information (SCI) or the control element (SL MAC CE) of the sidelink media access control layer. Each beam indicator may be associated with a time-frequency domain resource.

[0290] For example, taking a sensing scenario involving only the base station as an example, the beam configuration scheme can be determined through one or more of the following interactive recommendations: the base station can send recommended or unrecommended beam information to other base stations via Xn signaling; the base station sends recommended or unrecommended beam information to the sensing core network; and the sensing core network sends recommended or unrecommended beam information to the base station.

[0291] In some embodiments, beam information is bound to at least one of the following parameters: sensing area index, timestamp, receiving beam, receiving quasi-co-located resource, transmitting beam, spatial relationship of transmission, resource index of signal, and first indication information; wherein the first indication information is used to indicate whether the beam information is a recommended beam or a non-recommended beam.

[0292] The following describes how the power control scheme is determined in different scenarios:

[0293] The interfered party and the interfering party employ different power control schemes. For example, the interfered party can maximize its transmission power, while the interfering party can reduce its transmission power to mitigate the impact of interference.

[0294] For example, as shown in Figure 15, in the sensing mode where the base station transmits and the terminal receives, although communication and sensing are not on the same symbol, there may be interference between the terminal receiving the downlink sensing signal from base station 1 and the terminal receiving the downlink communication signal / channel from base station 2. To mitigate the interference of sensing on communication, the power of the downlink communication signal / channel transmitted by base station 2 can be increased or the power of the downlink sensing signal transmitted by base station 1 can be decreased.

[0295] For example, in a sensing mode where the base station transmits and the terminal receives, one or more of the following signaling methods can be introduced to reduce interference:

[0296] (1) The terminal sends downlink sensing signal power requirement information to the sensing core network or base station, wherein the power requirement information may include at least one of the following:

[0297] The following parameters are considered: power adjustment amount for downlink sensing signal resources or power adjustment amount for downlink sensing signal resource sets, where power can be power spectral density, energy per resource element (EPRE), or power configuration parameters such as P0 or alpha; power adjustment range for downlink sensing signal resources or resource sets; downlink sensing signal resource index or downlink sensing signal resource set index; downlink sensing signal configuration index; time information, such as timestamps or time windows, start times, or durations; recommended power range for downlink sensing signals, such as recommended power spectral density ranges; unrecommended power ranges for downlink sensing signals, such as unrecommended power spectral density ranges; path loss reference signal type or path loss reference signal index; associated beam information, such as downlink receive beam or downlink transmit beam.

[0298] (2) The terminal can also send the recommended communication signal power to the base station via signaling (such as MAC CE).

[0299] (3) After receiving the downlink sensing signal power configuration recommendation sent by the terminal, the sensing core network can instruct the base station to make corresponding adjustments.

[0300] (4) The sensing core network may send one or more pre-configured sensing signal configurations to the terminal. Each pre-configured sensing signal can be associated with at least one of the following parameters: pre-configuration index, sensing signal resource index, sensing signal resource set index, sensing signal transmission power, bandwidth, number of combs, period, number of repetitions, time domain length, and beam configuration.

[0301] (5) The terminal can request a set of pre-configured sensing signal configurations from the sensing core network, and the request signaling includes a pre-configured index.

[0302] (6) The sensing core network can send power information of suggested downlink sensing signal resources or downlink sensing signal resource sets to the base station. The power information of suggested downlink sensing signal resources or downlink sensing signal resource sets may include at least one of the following: downlink sensing signal power adjustment amount, wherein the power can be power spectral density or EPRE or power configuration parameters, such as P0 or alpha; downlink sensing signal power adjustment range; downlink sensing signal resource index or downlink sensing signal configuration index; time information, such as timestamp or time window, start time, or duration; recommended power range of downlink sensing signals, such as recommended power spectral density range; unrecommended power range of downlink sensing signals, such as unrecommended power spectral density range; path loss reference signal type or path loss reference signal index; associated beam information, such as receive beam or transmit beam.

[0303] For example, in the terminal-sent sensing mode, the receiving terminal or the receiving base station (not the service station) can send uplink / side-link sensing signal power recommendation information to the interfering terminal or to the sensing core network.

[0304] For the sensing mode where the terminal transmits and the base station receives, one or more of the following signaling methods can be introduced to reduce interference:

[0305] (1) The base station sends the power requirement information of the uplink sensing signal to the sensing core network. The base station can be the serving station or neighboring station of the terminal. The power requirement information of the uplink sensing signal may include at least one of the following: the uplink sensing signal power adjustment amount, wherein the power can be the power spectral density or EPRE or power configuration parameters, such as P0 or alpha; the uplink sensing signal power adjustment range; the uplink sensing signal resource index or the uplink sensing signal configuration index or the uplink sensing signal resource set index; time information, such as timestamp or time window, start time, or duration; the recommended power range of the uplink sensing signal, such as the recommended power spectral density range; the unrecommended power range of the uplink sensing signal, such as the unrecommended power spectral density range; the path loss reference signal type or the path loss reference signal index; and the associated beam information, such as the uplink receiving beam or the uplink transmitting beam.

[0306] (2) The base station can also send a recommended signal power to the serving base station of the terminal through Xn signaling. The recommended signal power can be associated with a certain sensing signal resource index, or the recommendation can be associated with a certain sensing signal resource set index.

[0307] (3) After receiving the uplink sensing signal power configuration recommendation sent by the base station, the sensing core network can instruct the terminal or the terminal's serving base station to make corresponding adjustments.

[0308] (4) The sensing core network may send one or more pre-configured sensing signal configurations to the base station. Each pre-configured sensing signal can be associated with at least one of the following parameters: pre-configuration index, sensing signal transmission power, bandwidth, number of combs, period, number of repetitions, time domain length, and beam configuration.

[0309] (5) The base station can request a set of pre-configured sensing signal configurations from the sensing core network, and the request signaling includes a pre-configured index.

[0310] For example, in a sensing mode where terminals transmit and receive (which may include self-transmission and self-reception by the terminal, or transmission by terminal A and reception by terminal B), one or more of the following signaling methods can be introduced to reduce interference:

[0311] (1) The terminal sends downlink sensing signal power requirement information to the sensing core network. The downlink sensing signal power requirement information may include at least one of the following: the power adjustment amount of the sideline sensing signal, wherein the power can be the power spectral density or EPRE or power configuration parameters, such as P0 or alpha; the power adjustment range of the sideline sensing signal; the resource index or configuration index of the sideline sensing signal; time information, such as timestamp or time window, start time, or duration; the recommended power range of the sideline sensing signal, such as the recommended power spectral density range; the unrecommended power range of the sideline sensing signal, such as the unrecommended power spectral density range; the path loss reference signal type or path loss reference signal index; and the associated beam information, such as the sideline receiving beam or the sideline transmitting beam.

[0312] (2) After receiving the recommended power configuration of the side-line sensing signal sent by the terminal, the sensing core network can instruct the terminal or the terminal's serving base station to make corresponding adjustments.

[0313] (3) The terminal can also send recommended power configurations to other terminals through sidechain signaling. The sidechain signaling can be PC5-RRC, SL MAC CE, SCI or higher layer signaling.

[0314] (4) The sensing core network may send one or more pre-configured sensing signal configurations to the terminal. Each pre-configured sensing signal can be associated with at least one of the following parameters: pre-configuration index, sensing signal resource index, sensing signal resource set index, sensing signal transmission power, bandwidth, number of combs, period, number of repetitions, time domain length, and beam configuration.

[0315] (5) The terminal can request a set of pre-configured sensing signal configurations from the sensing core network, and the request signaling includes a pre-configured index.

[0316] (6) The base station may send one or more pre-configured sensing signal configurations to the terminal. Each pre-configured sensing signal can be associated with at least one of the following parameters: pre-configuration index, sensing signal resource index, sensing signal resource set index, sensing signal transmission power, bandwidth, number of combs, period, number of repetitions, time domain length, and beam configuration.

[0317] (7) The terminal may request a set of pre-configured sensing signal configurations from the terminal, and the request signaling includes a pre-configured index.

[0318] For example, in a sensing mode where base stations transmit and receive (which may include base station self-transmission and self-reception, or base station A transmitting and base station B receiving), one or more of the following signaling methods can be introduced to reduce interference:

[0319] (1) The base station sends power requirement information of the sensing signal to the sensing core network. The power requirement information of the sensing signal may include at least one of the following: power adjustment amount of the sensing signal, wherein the power can be power spectral density or EPRE or power configuration parameters, such as P0 or alpha; power adjustment range of the sensing signal; sensing signal resource index or sensing signal configuration index or sensing signal resource set index; time information, such as timestamp or time window, start time, or duration; recommended power range of the sensing signal, such as recommended power spectral density range; unrecommended power range of the sensing signal, such as unrecommended power spectral density range; path loss reference signal type or path loss reference signal index; associated beam information, such as receive beam or transmit beam.

[0320] (2) After receiving the recommended power configuration of the sensing signal sent by the base station, the sensing core network can instruct other base stations to make corresponding adjustments.

[0321] (3) The base station can send the power requirements of the sensing signal to other base stations through the Xn interface.

[0322] (4) The sensing core network may send one or more pre-configured sensing signal configurations to the base station. Each pre-configured sensing signal can be associated with at least one of the following parameters: pre-configuration index, sensing signal resource index, sensing signal resource set index, sensing signal transmission power, bandwidth, number of combs, period, number of repetitions, time domain length, and beam configuration.

[0323] (5) The base station can request a set of pre-configured sensing signal configurations from the sensing core network, and the request signaling includes a pre-configured index.

[0324] (6) The sensing core network can send suggested power information to the base station, such as: the amount of sensing signal power adjustment, where the power can be power spectral density or EPRE or power configuration parameters, such as P0 or alpha; the range of sensing signal power adjustment; the sensing signal resource index or sensing signal configuration index or sensing signal resource set index; time information, such as timestamp or time window, start time, or duration; the recommended power range of the sensing signal, such as the recommended power spectral density range; the unrecommended power range of the sensing signal, such as the unrecommended power spectral density range; the path loss reference signal type or path loss reference signal index; and associated beam information, such as the receive beam or transmit beam.

[0325] For example, as shown in FIG16, the process of mitigating interference by adjusting power may include at least one of the following operations.

[0326] Operation 1: If the sensing node is a terminal, the base station and the sensing core network first interact to configure the on-demand sensing signals that the base station can support. The sensing signal configuration includes the power configuration of a certain sensing signal resource or a set of sensing signal resources. If the sensing node is a base station, the sensing core network directly interacts with the sensing node to configure the sensing signals.

[0327] Operation 2: The core network of the sensing network sends pre-configuration information of the sensing signal to the sensing nodes, wherein the pre-configuration information includes power configuration.

[0328] Operation 3: The sensing node can send a first request signaling to the sensing core network. The request includes at least: requesting the pre-configuration of a certain sensing signal; or requesting specific on-demand sensing signal configuration parameters; or requesting the modification of a certain sensing signal configuration parameter.

[0329] Operation 4: The sensing core network can send a second request signaling to the sensing node to request the sensing node's capabilities or to request the sensing node's sensing measurement results or interference measurement reports. For example, the capabilities may include the power configuration that the sensing node can support.

[0330] Operation 5: The sensing node sends the first information to the sensing core network. The first information includes at least one of the following: capability information, sensing measurement results, and interference measurement results.

[0331] Operation 6: The sensing core network determines the transmission requirements of the sensing reference signal, determines the configuration of the sensing reference signal, or modifies the transmission parameters of the sensing reference signal.

[0332] Operation 7: If the sensing node is a terminal, the sensing core network can request the terminal's serving base station to reconfigure the sensing reference signal or request the sensing node's serving base station to modify the sensing parameter configuration. If the sensing node is a base station, the sensing core network can request the base station to reconfigure the sensing reference signal or request the sensing node to modify the sensing parameter configuration. The sensing parameter configuration includes power configuration.

[0333] Operation 8: The base station sends the updated sensing signal transmission configuration or reports error indications to the sensing core network.

[0334] Operation 9: The sensing core network sends the sensing signal transmission configuration to the sensing nodes. This configuration includes the updated sensing signal transmission configuration.

[0335] For example, as shown in Figure 17, a flow chart for configuring sensing signals when the sensing node is a base station is given, wherein the sensing signal configuration includes power configuration, which includes at least one of the following steps:

[0336] Operation 1: The core network of the sensing network collects possible interference information, such as interference measurement reports from sensing nodes;

[0337] Operation 2: The core network requests a new sensing signal configuration or a modification of sensing parameter configuration from the sensing node, such as requesting an adjustment of the sensing signal amount.

[0338] Operation 3: The sensing node sends the updated sensing signal to the sensing core network, either sending configuration information or reporting error indications.

[0339] The following describes the above-mentioned interference measurement resource configuration information and silent configuration scheme:

[0340] In sensing, the sensing core network can send mute configuration information to either the interference source node or the interfered node. Alternatively, the interfered node can send required, recommended, or discouraged mute configuration information to the interference source node. The interfered node can also send required, recommended, or discouraged mute configuration information to the sensing core network. For example, if the sensing core network is aware of interference issues in sensing, it can send mute configuration information to the transmitting node to prevent it from transmitting signals / channels on highly interfering resources; or, for example, if the sensing core network is aware of interference information for a certain time period or a certain beam direction, it can send mute configuration information to the receiving node to prevent it from receiving highly interfering signals / channels.

[0341] A mute configuration can be applied to a specific sensing signal resource or a set of sensing signal resources. A mute configuration can be applied to a specific time period, a specific repetition, or a specific period. Alternatively, a mute configuration can be applied to certain frequency domain resources, such as a specific physical resource block, resource element, or comb structure. A mute configuration can also be applied to a specific beam direction or a specific node.

[0342] In the sensing process, the sensing core network, as a core network element, can collect interference measurement results from multiple nodes. The sensing core network sends interference measurement resource configuration information to the nodes. This interference measurement resource can be a dedicated resource for interference measurement or based on existing sensing signals. The sensing core network can request interference measurement reports from nodes as additional measurement quantities. Alternatively, the base station can send interference measurement resource configuration information to the sensing nodes. Or, the sensing core network can request the base station to configure resources for interference measurement, and the base station will send the interference measurement resource configuration to the sensing nodes or the sensing core network. After receiving the interference measurement resource configuration information, the sensing nodes can perform measurements accordingly and obtain an interference measurement report. The content of the interference measurement report is as described above.

[0343] The configuration information for interference measurement resources may include at least one of the following: the index of the interference measurement resource, the starting frequency domain position, the bandwidth, the number of physical resource blocks, the starting position in the time domain, the duration, the period, the number of repetitions, zero-power interference measurement resources, and non-zero-power interference measurement resources.

[0344] Interference resources can be zero-power signal resources or non-zero-power signal resources. For example, the sensing core network sends zero-power interference signal resource configurations and non-zero-power interference signal resource configurations to sensing nodes.

[0345] For example, if interference measurement is performed based on sensing signals, the sensing core network can perform at least one of the following: designate a certain sensing signal resource for interference measurement, or mute a certain sensing signal resource for interference measurement; convert a certain period into a zero-power sensing signal for interference measurement; or mute a certain period of sensing signal resources or a set of sensing signal resources; convert a certain repetition into a zero-power sensing signal; or mute a certain repetition of sensing signal resources or a set of sensing signal resources; convert sensing signals at certain time points (such as certain symbols) into zero-power sensing signals, or mute sensing signal resources or sets of sensing signals at certain times or certain symbols;

[0346] Transform the sensing signal resource, or certain physical resource blocks or frequency domain resources of the sensing signal resource, into zero power, such as by changing the comb size of the sensing signal resource, or by muting certain physical resource blocks or frequency domain resources of the sensing signal.

[0347] For example, a sensing node may also request, on demand, at least one of the following from the sensing core network, or a receiving sensing node may request, on demand, at least one of the following from the sensing node: specifying a sensing signal resource for interference measurement, or muting a sensing signal resource for interference measurement; converting a period into a zero-power sensing signal for interference measurement, or muting a sensing signal resource or set of sensing signals for a period; converting a repetition into a zero-power sensing signal, or muting a repetition of a sensing signal resource or set of sensing signals; converting sensing signals at certain time points (e.g., certain symbols) into zero-power sensing signals, or muting sensing signal resources or sets of sensing signals at certain times or certain symbols; converting sensing signal resources or certain physical resource blocks or frequency domain resources of sensing signal resources into zero power, such as changing the comb size of sensing signal resources, or muting certain physical resource blocks or frequency domain resources of sensing signals.

[0348] For example, Figures 18-22 illustrate several types of sensing signal mute configurations or zero-power sensing signal configurations. The sensing core network can configure a bitmap, or sensing nodes can request bitmap configuration, wherein the bit length of the bitmap is configurable, indicating that sensing signal resources or sets of sensing signal resources are configured to zero power or be mute at certain times of one or more cycles.

[0349] For example, Figure 18(a) shows the initial configuration of the sensing signal resource set, including a first sensing signal resource, a second sensing signal resource, a third sensing signal resource, and a fourth sensing signal resource; Figure 18(b) shows the second sensing signal resource muted for a certain period; and Figure 18(c) shows the sensing signal resource set muted for a certain period.

[0350] For example, Figure 19(a) shows the initial configuration of the sensing signal resource set, including a first sensing signal resource and a second sensing signal resource; Figure 19(b) shows the second sensing signal resource repeated in each silence cycle; and Figure 19(c) shows the sensing signal resource set repeated in each silence cycle.

[0351] For example, Figure 20(a) shows the initial configuration of the sensing signal resource set, including the first sensing signal resource, the second sensing signal resource, the third sensing signal resource, and the fourth sensing signal resource; Figure 20(b) shows the second sensing signal resource during the silent target time period (i.e., the time period from T1 to T2 in the figure); Figure 20(c) shows the sensing signal resource set during the silent target time period.

[0352] For example, certain frequency domain resources of the sensing signal resource set can be muted, such as as shown in Figure 21, by muting comb structure 1 (comb1) into comb structure 2 (comb2). The original comb structure size of the sensing reference signal is 1. The sensing node can request the sensing core network or the sensing core network can mute some resource blocks of comb structure 1. The remaining resource blocks of the comb structure can be used to measure interference.

[0353] For example, Figure 22(a) shows the initial configuration of the sensing signal resource set, including the first sensing signal resource, the second sensing signal resource, the third sensing signal resource, and the fourth sensing signal resource; Figure 22(b) shows some frequency domain resources of the second sensing signal resource during the silent target time period (i.e., the time period from T1 to T2 in the figure).

[0354] For example, the sensing core network may send one or more pre-configured sensing signal mute configurations or zero-power sensing signal configurations to sensing nodes, with each pre-configuration associated with a pre-configuration index. A sensing node may request one of these pre-configured sensing signal mute configurations or zero-power sensing signal configurations from the sensing core network, with the request signaling including the pre-configuration index.

[0355] For example, the base station of the sensing node can provide the sensing node with one or more pre-configured sensing signal mute configurations or zero-power sensing signal configurations, each pre-configuration being associated with a pre-configuration index. The sensing node can request one of the pre-configured sensing signal mute configurations or zero-power sensing signal configurations from the base station, with the request signaling including the pre-configuration index.

[0356] For example, other base stations can provide the base station with one or more pre-configured sensing signal mute configurations or zero-power sensing signal configurations, each pre-configuration being associated with a pre-configuration index. The base station can request one of these pre-configured sensing signal mute configurations or zero-power sensing signal configurations from other base stations, with the request signaling including the pre-configuration index.

[0357] For example, other terminals can provide the terminal with one or more pre-configured sensing signal mute configurations or zero-power sensing signal configurations, each pre-configuration being associated with a pre-configuration index. The terminal can request one of these pre-configured sensing signal mute configurations or zero-power sensing signal configurations from other terminals, with the request signaling including the pre-configuration index.

[0358] The sensing core network can request interference measurement reports from sensing nodes, which may include received signal strength indications or reference signal received power. Furthermore, the sensing core network can configure one or more pre-configured sensing signal mute configurations or zero-power sensing signal configurations.

[0359] As an example, based on the above scheme, the following methods can be adopted to address interference between sensing nodes and positioning nodes:

[0360] If the interfered node is a sensing node, after receiving the interference information from the sensing node, the sensing core network requests resource configuration information for the positioning signal from the positioning core network. This configuration may be limited to a certain frequency domain range or a certain time range. The sensing core network may send at least one of the following to the positioning core network or the nodes participating in the positioning: an interference measurement report from the sensing node, the relevant information contained in the interference measurement report can be referred to in other embodiments; recommended or not recommended beam information; recommended or not recommended power configuration information; recommended silent positioning resources, where "silent" can be for a certain positioning reference signal resource, or for a certain beam direction, for certain frequency domain resources, or for certain time domain resources.

[0361] If the affected node is a location node, the location core network can also request resource configuration information of the sensing signal from the sensing core network for interference measurement. This configuration may be limited to a certain frequency domain range or a certain time range. The location core network can send at least one of the following to the sensing core network or participating nodes: an interference measurement result report of the location node, the information contained in the interference measurement report can be referred to in other embodiments; recommended or not recommended beam information; recommended or not recommended power configuration information; recommended silent sensing resources, where "silent" can be for a certain sensing reference signal resource, or for a certain beam direction, for certain frequency domain resources, or for certain time domain resources.
