Description

Interference measurement method and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 25, 2023, with application number 202311603460.9 and invention name “An interference measurement method and related device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and in particular to an interference measurement method and related devices. Background Art

[0003] Interference in communications arises from the overlap of communication signals from different users in the time, frequency, or spatial domains. This causes the signals to interfere with each other, ultimately degrading communication performance. To improve communication performance, communication devices perform interference measurements to obtain interference measurement results. These results are then used to implement processes such as communication link management, channel estimation, and data demodulation.

[0004] Similar to interference in communications, interference can also exist in perception scenarios. For example, other signals may interfere with the perception signal during the perception measurement, ultimately degrading perception performance. To improve perception performance, interference management, such as interference measurement, is also necessary.

[0005] However, traditional interference measurement techniques perform interference measurements on a time-frequency resource grid defined during communication. In sensing scenarios, when the time-frequency resources occupied by the interfering signal overlap with those used for sensing measurement, this may not affect the sensing measurement. Therefore, the interference measurement resources used in traditional techniques may not be suitable for measuring interference levels in sensing scenarios.

[0006] Summary of the Invention

[0007] The present application provides an interference measurement method and related devices for measuring the interference level to perception in a perception scenario and improving the accuracy of interference measurement in the perception scenario.

[0008] In a first aspect, the present application provides an interference measurement method, which can be performed by a perception device or by a component of the perception device (for example, a processor, a chip, or a chip system). Taking the perception device as an example, before or during the perception measurement, the perception device obtains a first interference measurement resource, where the first interference measurement resource is related to the measurement dimension of the perception measurement of the perception device; then, the perception device receives an interference measurement signal sent by the interfering device through the first interference measurement resource.

[0009] In the present application, since the first interference measurement resource for transmitting the interference measurement signal between the perception device and the interfering device is related to the measurement dimension of the perception measurement of the perception device, the interference measurement signal can reflect the interference of the interfering device on the perception device in the measurement dimension of the perception measurement, which is beneficial for the perception device to more accurately detect the impact of the interfering device on the perception device and improve the accuracy of interference measurement in the perception scenario.

[0010] In a possible implementation, the first interference measurement resource is related to the interference measurement range, and the interference measurement range is the effective measurement range of the perception measurement in the measurement dimension. Optionally, the interference measurement range is used to indicate the range in which the perception measurement cannot tolerate interference. It can be understood that when the projection of the interference measurement signal in the measurement dimension after perception processing falls into the interference measurement range, the interference measurement signal will interfere with the perception measurement; when the projection of the interference measurement signal in the measurement dimension after perception processing does not fall into the interference measurement range, the interference measurement signal will not interfere with the perception measurement. This is beneficial for the perception device to determine whether it is affected by the interfering device within the interference measurement range, and is beneficial to further improve the accuracy of interference measurement in the perception scenario.

[0011] In a possible implementation, the interference measurement method further includes: the sensing device determining interference measurement information based on the interference measurement signal, where the interference measurement information is used to indicate interference conditions of the interference measurement signal on the sensing device in a sensing measurement dimension.

[0012] In this embodiment, the sensing device determines interference measurement information based on the received interference measurement signal and quantifies the interference experienced by the sensing device into a specific value, which is conducive to intuitively reflecting the interference experienced by the sensing device and facilitates subsequent interference management.

[0013] In a possible implementation, the interference measurement information includes an interference measurement value of the interference measurement signal in a measurement dimension. Optionally, the interference measurement information includes an interference measurement value of the interference measurement signal within an interference measurement range in the measurement dimension.

[0014] In this implementation, the interference measurement information determined by the sensing device can reflect the interference situation within the interference measurement range in the measurement dimension, which is beneficial to improving the accuracy and efficiency of subsequent interference management.

[0015] In one possible implementation, the sensing device obtains a first interference measurement resource, including: the sensing device sends a first interference measurement request, the first interference measurement request includes a measurement dimension of the sensing measurement and first resource indication information, the first resource indication information is used to indicate at least one first candidate interference measurement resource, each first candidate interference measurement resource is related to the measurement dimension of the sensing measurement; the sensing device receives a first interference measurement response, the first interference measurement response includes second resource indication information, the second resource indication information is used to indicate the first interference measurement resource. The first interference measurement resource is determined based on the at least one first candidate interference measurement resource.

[0016] In this embodiment, the sensing device triggers negotiation with the interfering device to determine the first interference measurement resource, which facilitates the sensing device to initiate interference measurement when interference management is required, thereby enabling the sensing device to perform interference measurement on demand and improving the flexibility of interference measurement. In addition, the first interference measurement request includes the measurement dimension of the sensing measurement, which facilitates the interfering device to take the measurement dimension of the sensing measurement into consideration when determining the first interference measurement resource, so that the interfering device can determine a resource that is more suitable for measuring interference in the measurement dimension, thereby improving the accuracy of the interference measurement.

[0017] Optionally, the first interference measurement request also includes an interference measurement range, and the first candidate interference measurement resource is related to the interference measurement range. This helps the interfering device take the interference measurement range into consideration when determining the first interference measurement resource, so that the interfering device can determine a resource that is more suitable for measuring interference in the measurement dimension, thereby improving the accuracy of the interference measurement.

[0018] In one possible implementation, the interference measurement method further includes: the sensing device determining at least one first candidate interference measurement resource based on a measurement dimension of the sensing measurement and a first correspondence, where the first correspondence includes at least one measurement dimension and at least one interference measurement resource corresponding to each measurement dimension. The first correspondence may be specified by a protocol or preconfigured, and is not limited in this application.

[0019] In this implementation, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension and the first corresponding relationship, which is conducive to improving the efficiency of determining the first candidate interference measurement resource and saving processing overhead of the sensing device.

[0020] In a possible implementation, the interference measurement method further includes: the sensing device determining at least one first candidate interference measurement resource based on a measurement dimension of the sensing measurement and an interference measurement range.

[0021] In this embodiment, since the sensing device considers the measurement dimension and interference measurement range of the sensing measurement when determining the first candidate interference measurement resource, it is beneficial for the sensing device to determine the candidate resource suitable for measuring interference measurement, thereby improving the accuracy of interference measurement.

[0022] In one possible implementation, the sensing device acquires the first interference measurement resource, including: the sensing device receives a second interference measurement request, the second interference measurement request includes third resource indication information, and the third resource indication information is used to indicate at least one second candidate interference measurement resource supported by the interfering device; and the sensing device sends a second interference measurement response, the second interference measurement response includes fourth resource indication information, and the fourth resource indication information is used to indicate the first interference measurement resource. The first interference measurement resource is determined based on the at least one second candidate interference measurement resource.

[0023] In this implementation, the interfering device triggers negotiation with the sensing device to determine the first interference measurement resource, which can enable the interfering device to actively trigger interference management in a scenario with fewer interfering devices, thereby improving the efficiency of interference management.

[0024] In a possible implementation, the interference measurement method further includes: the sensing device determining a first interference measurement resource based on a measurement dimension of the sensing measurement and at least one second candidate interference measurement resource.

[0025] In this embodiment, the process of the perception device determining the first interference measurement resource based on at least one second candidate interference measurement resource takes into account the measurement dimension of the perception measurement, so that the perception device determines a resource that is more suitable for measuring the interference of the measurement dimension, thereby improving the accuracy of the interference measurement.

[0026] In a possible implementation, the sensing device determines the first interference measurement resource based on the measurement dimension of the sensing measurement and at least one second candidate interference measurement resource, including: the sensing device determines the first interference measurement resource based on the measurement dimension of the sensing measurement, the interference measurement range and at least one second candidate interference measurement resource.

[0027] In this embodiment, the process of the perception device determining the first interference measurement resource based on at least one second candidate interference measurement resource takes into account the measurement dimension and interference measurement range of the perception measurement, which is beneficial for the perception device to determine whether it is affected by the interference device within the interference measurement range, and is beneficial to further improve the accuracy of interference measurement in the perception scenario.

[0028] In a possible implementation, the second candidate interference measurement resource is related to a measurement dimension of the perception measurement.

[0029] In this embodiment, the second candidate interference measurement resource provided by the interfering device to the perception device not only takes into account the capabilities of the interfering device, but also takes into account the measurement dimension of the perception measurement, which is conducive to providing the perception device with more accurate candidate interference measurement resources suitable for a certain measurement dimension, and is also conducive to the perception device to more quickly determine the first interference measurement resource suitable for a certain measurement dimension, thereby helping to improve the efficiency of interference measurement.

[0030] In a possible implementation, the measurement dimension of the perception measurement includes any one of the following:

[0031] Distance measurement; or speed measurement; or angle measurement; or imaging measurement; or distance combined with speed measurement; or distance combined with angle measurement; or speed combined with angle measurement; or distance, speed and angle measurement.

[0032] In a possible implementation, the interference measurement method further includes: the perception device determines the parameters of the perception signal and / or the perception measurement resources occupied by the perception signal based on the interference measurement information; wherein the parameters of the perception signal include at least one of signal power, signal phase, or signal amplitude; and the perception measurement resources include at least one of time domain resources, frequency domain resources, or port resources.

[0033] In this embodiment, the perception device can determine the interference level of the interfering device to the perception device based on the interference measurement information. The perception device refers to the interference measurement information to determine the perception signal sent by the perception device in the subsequent perception measurement process, which is conducive to reducing the interference of the interfering device in the measurement dimension of the perception measurement, thereby effectively mitigating or eliminating the perception interference.

[0034] In a possible implementation, the interference measurement method further includes: if the interference level indicated by the interference measurement information is greater than a first threshold, the perception device sends first information to the interference device, the first information includes an interference measurement report, and the interference measurement report includes a measurement dimension of the perception measurement, interference measurement information, and a second threshold.

[0035] Optionally, the first threshold is the maximum interference that the sensing device can tolerate. For example, when the interference level experienced by the sensing device is greater than the first threshold, the sensing measurement service of the sensing device may not be performed normally.

[0036] Optionally, the second threshold is used to indicate the desired interference level of the sensing device. This can be understood as indicating the desired interference level for the sensing device during normal operation. This can also be understood as indicating the desired interference level that the sensing device recommends the interfering device reduce. Optionally, the second threshold is less than or equal to the first threshold.

[0037] In this embodiment, in order to reduce the interference caused by the interfering device to the sensing device, the sensing device, in addition to providing interference measurement information and measurement dimensions to the interfering device, also provides a reference value (i.e., the second threshold) for recommending the interfering device to lower the interference measurement signal to a certain extent, which is conducive to the interfering device to quickly and effectively adjust the interference and improve the efficiency and accuracy of interference management.

[0038] In a possible implementation, the interference measurement method further includes: if the interference level indicated by the interference measurement information is greater than a first threshold, the sensing device sends first information to the interfering device, the first information including at least one adjustment indication, each adjustment indication being used to instruct the interfering device to adjust a parameter of the interference measurement signal.

[0039] In this embodiment, the sensing device directly provides the interference device with an adjustment instruction for adjusting the interference measurement signal, and the interference device only needs to adjust the parameters of the interference measurement signal according to the adjustment instruction, which helps to save the processing overhead of the interference device for calculating the adjusted parameters.

[0040] In one possible implementation, the first information is used to instruct the interfering device to adjust the parameters of the interference measurement signal and / or the resources occupied by the interference measurement signal; wherein the parameters of the interference measurement signal include at least one of signal power, signal phase, or signal amplitude; and the resources include at least one of time domain resources, frequency domain resources, or port resources.

[0041] In this embodiment, the perception device can send first information to the interfering device. The first information provides a basis for the interfering device to adjust the interference measurement signal, which is conducive to the interfering device accurately adjusting the interference measurement signal to reduce the interference of the interfering device in the measurement dimension of the perception measurement, thereby effectively mitigating or eliminating the perception interference.

[0042] In a second aspect, the present application provides an interference measurement method, which can be performed by an interfering device or by a component of the interfering device (e.g., a processor, a chip, or a chip system). Taking the interfering device as an example, the interfering device obtains a first interference measurement resource, which is related to the measurement dimension of the perception measurement of the perception device; then, the interfering device sends an interference measurement signal through the first interference measurement resource.

[0043] In the present application, since the first interference measurement resource for transmitting the interference measurement signal between the perception device and the interfering device is related to the measurement dimension of the perception measurement of the perception device, the interference measurement signal can reflect the interference of the interfering device on the perception device in the measurement dimension of the perception measurement, which is beneficial for the perception device to more accurately detect the impact of the interfering device on the perception device and improve the efficiency of interference measurement in the perception scenario.

[0045] In a possible implementation, the interference measurement signal is used by the sensing device to determine interference measurement information based on the interference measurement signal, where the interference measurement information is used to indicate interference conditions of the interference measurement signal on the sensing device in a sensing measurement dimension.

[0046] In a possible implementation, the interference measurement information includes an interference measurement value of the interference measurement signal in a measurement dimension. Optionally, the interference measurement information includes an interference measurement value of the interference measurement signal within an interference measurement range in the measurement dimension.

[0047] In one possible implementation, the sensing device triggers acquisition of a first interference measurement resource. Specifically, the interfering device receives a first interference measurement request, the first interference measurement request includes a measurement dimension of the sensing measurement and first resource indication information, the first resource indication information is used to indicate at least one first candidate interference measurement resource, each first candidate interference measurement resource is related to the measurement dimension of the sensing measurement; then, the interfering device sends a first interference measurement response, the first interference measurement response includes second resource indication information, the second resource indication information is used to indicate the first interference measurement resource. The first interference measurement resource is determined based on the at least one first candidate interference measurement resource.

[0048] Optionally, before sending the first interference measurement response, the interfering device will further perform the following steps: the interfering device determines a first interference measurement resource based on a measurement dimension of the perception measurement and at least one first candidate interference measurement resource.

[0049] Optionally, if the first interference measurement request further includes an interference measurement range, the interfering device determines the first interference measurement resource based on the measurement dimension of the perception measurement and at least one first candidate interference measurement resource, including:

Specifically, the interfering device sends a second interference measurement request, the second interference measurement request includes third resource indication information, and the third resource indication information is used to indicate at least one second candidate interference measurement resource supported by the interfering device. Then, the interfering device receives a second interference measurement response, the second interference measurement response includes fourth resource indication information, and the fourth resource indication information is used to indicate the first interference measurement resource. The first interference measurement resource is determined based on the at least one second candidate interference measurement resource.

[0075] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0076] The terms "first," "second," "third," "fourth," and the like (if any) in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0077] It should be understood that the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be single or multiple. In addition, the character " / " in this article generally indicates that the previous and next associated objects are in an "or" relationship. In addition, "at least one of the following" or similar expressions in this article is used to represent any combination of the listed items; for example, at least one of A, B and (or) C can represent the following six situations: A exists alone, B exists alone, C exists alone, A and B exist at the same time, B and C exist at the same time, A and C exist at the same time, and A, B and C exist at the same time, where A, B, and C can be single or multiple.

[0078] The interference measurement method provided in this application is mainly used for interference measurement in perception scenarios. For example, before or during the perception measurement of the target object by the perception device, the perception device measures the interference of the interfering device on the perception device. The perception scenario mainly involves perception devices, interfering devices and target objects. Among them, the perception device can be an access network device, a terminal device or other device or apparatus that can realize the perception measurement function through wireless signals; the interfering device can be an access network device, a terminal device or other device that can transmit wireless signals and may cause interference to other communication devices; the target object can be a drone, a vehicle, a building and a roadside device, etc.

[0079] For example, Figure 1 illustrates a perception scenario. As shown in Figure 1, the perception device can be access network device 1, which performs perception measurements on target objects such as roadside devices and vehicles. The interfering device that may interfere with access network device 1 is access network device 2. For another example, the perception device can be terminal device 1, which performs perception measurements on target objects such as roadside devices and vehicles. The interfering device that may interfere with terminal device 1 can be either access network device 2 or terminal device 2.

[0080] Exemplarily, the aforementioned sensing device and / or interference device may be a 5G NR (5G New Radio) system, the 6th generation mobile communication technology (6G) system, and terminal devices and / or access network devices in subsequent evolutionary formats. The communication between the sensing device and the interference device may be cellular network communication or short-range communication (proximity communication, PC5), which is not limited in this application. For example, cellular network communication is adopted between the terminal device 1 as a sensing device and the access network device 2 as an interference device in Figure 1. For another example, PC5 communication is adopted between the terminal device 1 as a sensing device and the terminal device 2 as an interference device in Figure 1.

[0081] Among them, the terminal device includes a device that provides voice and / or data connectivity to the user. For example, it may include a handheld device with wireless connection function or a processing device connected to a wireless modem. In cellular network communications, the terminal device can communicate with the radio access network (RAN) through the Uu interface, and communicate with the core network (for example, the 5G core network (5th generation core, 5GC)) through the RAN. Optionally, in the PC5 communication scenario, the terminal device supports a direct communication interface (i.e., the PC5 interface) and can communicate with other terminal devices that support the PC5 interface through the PC5 interface. It should be understood that the terminal device may also be referred to as a terminal, user equipment (UE), wireless terminal device, mobile terminal (MT) device, subscriber unit, subscriber station, mobile station (MS), mobile, remote station, access point (AP), remote terminal device, access terminal device, user terminal device, user agent, or user device, etc. In addition, the terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) device, an augmented reality (AR) device, or an extended reality (XR) service terminal. In addition, the terminal device can also be an Internet of Things (IOT) terminal, for example, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like.

[0082] Furthermore, an access network device can be any device with wireless transceiver capabilities and can be responsible for air interface-related functions, such as radio link maintenance, radio resource management, and some mobility management functions. Furthermore, the access network device can be configured with a baseband unit (BBU) that performs baseband signal processing. Exemplarily, the access network device can be the radio access network (RAN) currently providing services to the terminal device. Currently, some common examples of access network equipment include: Node B (NB), evolved Node B (eNB or eNodeB), next generation Node B (gNB) in 5G new radio (NR) systems, nodes in 6G systems (e.g., xNodeB), transmission reception point (TRP), radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB or home NodeB (HNB)), etc. In addition, in network structures such as cloud radio access network (CloudRAN) or open radio access network (ORAN), access network equipment may include at least one of a centralized unit (CU) (also known as a control unit), a distributed unit (DU), and a radio unit (RU). Among them, the RAN equipment including CU and DU splits the protocol layer of gNB in ​​the NR system, centrally controls some protocol layer functions in CU, and distributes some or all of the remaining protocol layer functions in DU, which is centrally controlled by CU.

[0083] It should be understood that in actual applications, the sensing device and the interfering device can be implemented using any of the aforementioned examples. In this embodiment and subsequent embodiments, only the sensing device and the interfering device are used as examples for introduction.

[0084] Since the interference in the perception scenario is mainly due to the overlap of the perception signals of different users in one or more measurement dimensions, which causes different perception signals to affect each other, and ultimately reduces the perception performance. Therefore, to measure the interference in the perception scenario, it is necessary to define interference and measure interference in dimensions other than the time domain, frequency domain, and spatial domain in combination with the perception requirements. To this end, the present application provides an interference measurement method and related devices for measuring the level of interference to perception in a perception scenario, thereby improving the accuracy and efficiency of interference measurement in the perception scenario.

[0085] The main process of the interference measurement method provided by this application is introduced below in conjunction with Figure 2. The interference measurement method can be performed by a sensing device and an interference device, or by components of the sensing device and the interference device (for example, a processor, a chip, or a chip system). The following is an example of the execution by the sensing device and the interference device. As shown in Figure 2, the interference measurement method includes the following steps:

[0086] Step 201: The sensing device obtains a first interference measurement resource; accordingly, the interfering device obtains the first interference measurement resource.

[0087] The first interference measurement resource is a resource used to measure interference in a perception scenario. It can be understood that the first interference measurement resource is used to transmit an interference measurement signal in a perception scenario. For example, before or during a perception measurement, in order to avoid interference affecting the perception measurement, the perception device and the interfering device will obtain the first interference measurement resource, so that the interfering device can send the interference measurement signal through the first interference measurement resource, and the perception device can receive the interference measurement signal through the first interference measurement resource.

[0088] The first interference measurement resource is related to the measurement dimension of the perception measurement of the perception device. It can be understood that the time domain characteristics, frequency domain characteristics, or spatial domain characteristics of the first interference measurement resource match the measurement dimension of the perception measurement. It can also be understood that the interference measurement signal transmitted on the first interference measurement resource has a high probability of interfering with the perception measurement of the perception device in the measurement dimension.

[0089] Optionally, the measurement dimension of the perception measurement includes any one of the following: distance measurement; or speed measurement; or angle measurement; or imaging measurement; or distance combined with speed measurement; or distance combined with angle measurement; or speed combined with angle measurement; or distance, speed and angle measurement.

[0090] It should be understood that for different measurement dimensions, the first interference measurement resource has different time domain characteristics, frequency domain characteristics or spatial domain characteristics. The following is a simple example:

[0091] In one example, if the measurement dimension is distance measurement, the frequency domain bandwidth of the first interference measurement resource needs to meet the constraint. For example, the frequency domain bandwidth of the first interference measurement resource is greater than the first threshold. It can be understood that when the sensing device measures whether there is interference in the distance dimension, configuring the first interference measurement resource to have a larger frequency domain bandwidth is beneficial for the sensing device to obtain a higher distance resolution during interference measurement, so as to more accurately detect whether the sensing device has interference, that is, to improve the accuracy of interference measurement in the scenario of sensing distance.

[0092] In another example, if the measurement dimension is speed measurement, the time domain characteristics of the first interference measurement resource need to meet the constraints. For example, the duration of the first interference measurement resource in the time domain is greater than the second threshold and / or the time domain repetition period is less than the third threshold. It can be understood that when the perception device measures whether there is interference in the speed dimension, configuring the first interference measurement resource with a longer duration and a smaller time domain repetition interval is beneficial for the perception device to obtain a higher speed resolution and a larger speed measurement range during interference measurement, thereby improving the accuracy of interference measurement in the scenario of perception speed.

[0093] In another example, if the measurement dimension is an angle measurement, the spatial characteristics of the first interference measurement resource need to meet the constraints. The spatial characteristics include the characteristics of the antenna port. For example, the number of antenna ports involved in the first interference measurement resource is greater than the fourth threshold. It can be understood that when the sensing device measures whether there is interference in the angle dimension, configuring the first interference measurement resource to involve as many antenna ports as possible is beneficial for the sensing device to obtain higher angular resolution during interference measurement, thereby improving the accuracy of interference measurement in the scenario of sensing angle.

[0094] In another example, if the measurement dimension is imaging measurement, the frequency domain bandwidth and spatial domain characteristics of the first interference measurement resource need to meet constraints. The spatial domain characteristics include antenna port characteristics. For example, the frequency domain bandwidth of the first interference measurement resource is greater than the fifth threshold, and / or the number of antenna ports involved in the first interference measurement resource is greater than the sixth threshold. It can be understood that when the sensing device measures whether there is interference in the imaging dimension, configuring the first interference measurement resource with a larger bandwidth and involving more antenna ports is beneficial for the sensing device to obtain higher distance and angular resolution during interference measurement, thereby obtaining higher imaging resolution and improving the accuracy of interference measurement in the sensing imaging scenario. In another example, if the measurement dimension is distance combined with speed measurement, that is, the sensing measurement measures both distance and speed, then the first interference measurement resource needs to meet both the constraints on distance measurement and the constraints on speed measurement. For example, the frequency domain bandwidth and time domain characteristics of the first interference measurement resource need to meet constraints. For details, please refer to the example where the measurement dimension is distance and the example where the measurement dimension is speed.

[0095] In another example, if the measurement dimension is distance combined with angle measurement, that is, the perception measurement measures both distance and angle, then the first interference measurement resource must meet both the constraints for distance measurement and the constraints for angle measurement. For example, both the frequency domain bandwidth and spatial domain characteristics of the first interference measurement resource must meet the constraints. For details, please refer to the example where the measurement dimension is distance and the example where the measurement dimension is angle.

[0096] In another example, if the measurement dimension is speed combined with angle measurement (i.e., the perceptual measurement measures both speed and angle), the first interference measurement resource must satisfy both speed and angle measurement constraints. For example, both the time domain and spatial domain characteristics of the first interference measurement resource must satisfy the constraints. For details, see the example where the measurement dimension is speed and the example where the measurement dimension is angle.

[0097] In another example, if the measurement dimension is distance, speed, and angle measurement, that is, the perception measurement simultaneously measures distance, speed, and angle, then the first interference measurement resource must simultaneously meet the constraints for distance measurement, speed measurement, and angle measurement. For example, the frequency domain bandwidth, time domain characteristics, and spatial domain characteristics of the first interference measurement resource must all meet the constraints. For details, please refer to the example with distance as the measurement dimension, the example with speed as the measurement dimension, and the example with angle as the measurement dimension.

[0098] It should be understood that in actual applications, for a certain measurement dimension, the first interference measurement resource may have other constraints in the time domain, frequency domain or spatial domain, and this application will not list examples one by one.

[0099] Optionally, the first interference measurement resource is related to the interference measurement range, and the interference measurement range is the effective measurement range of the perception measurement in the measurement dimension. It can be understood that the first interference measurement resource is not only related to the measurement dimension of the perception measurement, but also related to the effective measurement range of the perception measurement in the measurement dimension.

[0100] Optionally, the interference measurement range is used to indicate a range within which the perception measurement cannot tolerate interference. It can be understood that when the projection of the interference measurement signal in the measurement dimension after perception processing falls within the interference measurement range, the interference measurement signal will interfere with the perception measurement; when the projection of the interference measurement signal in the measurement dimension after perception processing does not fall within the interference measurement range, the interference measurement signal will not interfere with the perception measurement.

[0101] Exemplarily, if the measurement dimension is distance measurement, the interference measurement range is the effective measurement range in the distance dimension, and the first interference measurement resource is related to the interval length of the effective measurement range in the distance dimension. For example, if the measurement dimension is distance measurement, and the interval length of the interference measurement range is h, the time domain repetition period of the first interference measurement resource is greater than c / h (where c is the speed of light). For example, the interference measurement range is 0m to 1000m, the interval length of the interference measurement range is 1000m, and the time domain repetition period of the first interference measurement resource is greater than c / (1000m). Exemplarily, if the measurement dimension is speed measurement, the interference measurement range is the effective measurement range in the speed dimension, and the first interference measurement resource is related to the interval length of the effective measurement range in the speed dimension. For example, if the measurement dimension is speed measurement, and the interval length of the interference measurement range is 2v, the time domain repetition period of the first interference measurement resource is less than λ / (2v) (where λ is the carrier wavelength). For example, the interference measurement range is -30m / s to +30m / s, the interval length of the interference measurement range is 2×30m / s, and the time domain repetition period of the first interference measurement resource is less than λ / (2×30m / s) (where λ is the carrier wavelength). Similarly, when the measurement dimension is angle measurement, imaging measurement, and joint measurement, the time domain characteristics, frequency domain characteristics, or spatial domain characteristics of the first interference measurement resource will also be affected by the interference measurement range in the measurement dimension. Examples are not listed here one by one.

[0102] It should be noted that the first interference measurement resource can be an interference measurement resource (IMR) reused in a traditional technology, or a resource newly defined for interference measurement for a perception scenario, and this application is not limited. Exemplarily, if the first interference measurement resource is an IMR reused in a traditional technology, the first interference measurement resource can be a channel state information reference signal (CSI-RS) resource or a demodulation reference signal (DM-RS) resource. Among them, CSI-RS resources include non-zero power (NZP) CSI-RS resources and zero power (ZP) CSI-RS resources.

[0103] In addition, the sensing device and the interfering device can obtain the first interference measurement resource separately, or they can determine the first interference measurement resource through negotiation after signaling exchange. The following are introduced respectively:

[0104] In one possible implementation, the sensing device and the interfering device each obtain a first interference measurement resource. For example, the sensing device receives pre-configured first configuration information or first configuration information from another communication device, where the first configuration information is used to configure the first interference measurement resource. For another example, the interfering device receives pre-configured second configuration information or second configuration information from another communication device, where the second configuration information is used to configure the first interference measurement resource.

[0105] In another possible implementation, the sensing device and the interfering device determine the first interference measurement resource after signaling interaction, that is, the first interference measurement resource is an interference measurement resource determined by negotiation after signaling interaction between the sensing device and the interfering device.

[0106] In one implementation, the sensing device triggers negotiation to determine a first interference measurement resource. For example, the sensing device sends at least one first candidate interference measurement resource to the interfering device, and the interfering device determines the first interference measurement resource based on its own capabilities and with reference to the at least one candidate interference measurement resource. For details, please refer to the relevant description of the embodiment corresponding to FIG. 4 below, which is not repeated here.

[0107] In another implementation, the interfering device triggers negotiation to determine the first interference measurement resource. For example, the interfering device provides at least one second candidate interference measurement resource to the sensing device, and the sensing device determines the first interference measurement resource based on information such as the measurement dimension of the sensing measurement and with reference to the at least one second candidate interference measurement resource. For details, please refer to the relevant description of the embodiment corresponding to FIG. 5 below, which is not repeated here.

[0108] In step 202, the interfering device sends an interference measurement signal through a first interference measurement resource; accordingly, the sensing device receives the interference measurement signal sent by the interfering device through the first interference measurement resource.

[0109] The interference measurement signal generally refers to a signal sent by an interfering device through a first interference measurement resource. The interference measurement signal may be a newly defined signal of the interfering device, an operating signal of the interfering device, or a signal preconfigured in the interfering device, which is not limited in this application. When the measurement dimensions associated with the first interference measurement resource are different, the interference measurement signal may be different.

[0110] In one possible implementation, if the sensing device and the interfering device respectively obtain a first interference measurement resource, then when interference measurement is required, the sensing device sends an instruction to the interfering device to trigger the interfering device to send an interference measurement signal on the first interference measurement resource; or, the interfering device sends an interference measurement signal on the first interference measurement resource based on a preconfigured trigger period or trigger event.

[0111] In another possible implementation, if the sensing device and the interfering device negotiate and determine the first interference measurement resource through signaling interaction, then when the interfering device notifies the sensing device that the first interference measurement resource has been selected or when the interfering device receives an indication from the sensing device that the first interference measurement resource has been selected, the interfering device triggers the sending of an interference measurement signal through the first interference measurement resource. For details, please refer to the relevant description in the corresponding embodiments of FIG. 4 or FIG. 5 below, which will not be repeated here.

[0112] Step 203: The sensing device determines interference measurement information based on the interference measurement signal.

[0113] In this embodiment, step 203 is optional. It should be understood that the sensing device may calculate interference measurement information each time it receives an interference measurement signal. Furthermore, the sensing device may trigger the determination of interference measurement information based on at least one interference measurement signal only when the number of consecutive interference measurement signal receptions reaches a threshold, or when the duration of waiting to receive an interference measurement signal reaches a threshold. This application is not limiting.

[0114] Specifically, the sensing device performs sensing processing on the interference measurement signal in the sensing measurement dimension and outputs interference measurement information, wherein the interference measurement information is used to indicate the interference condition of the interference measurement signal on the sensing device in the sensing measurement dimension.

[0115] It should be understood that the measurement dimensions associated with the first interference measurement resources are different, resulting in differences in the interference measurement signals received by the perception device, and further resulting in different interference measurement information determined by the perception device.

[0116] Exemplarily, if the measurement dimension of the perception measurement is distance measurement, the perception device performs pulse compression processing of the fast time dimension (i.e., the distance dimension) on the received interference measurement signal to obtain interference measurement information of the distance dimension. Exemplarily, if the measurement dimension of the perception measurement is speed measurement, the perception device performs matched filtering processing of the slow time dimension (i.e., the speed dimension) on the received interference measurement signal to obtain interference measurement information of the speed dimension or Doppler dimension. Exemplarily, if the measurement dimension of the perception measurement is angle measurement, the perception device performs matching filtering or super-resolution estimation of the array angle dimension on the received interference measurement signal to obtain interference measurement information of the angle dimension. Exemplarily, if the measurement dimension of the perception measurement is imaging measurement, the perception device performs imaging processing (e.g., back projection (BP) algorithm processing or wavenumber domain algorithm processing, etc.) on the received interference measurement signal to obtain interference measurement information of the imaging space dimension.

[0117] Optionally, the interference measurement information includes an interference measurement value of the interference measurement signal in the measurement dimension. Optionally, the interference measurement information includes at least one of the following interference measurement values:

[0118] The average power of the interference measurement signal in the measurement dimension after perception processing; or, the peak power of the interference measurement signal in the measurement dimension after perception processing; or, the ratio of the power of the interference measurement signal after perception processing to the preset power.

[0119] Optionally, the interference measurement information includes an interference measurement value of the interference measurement signal within the interference measurement range on the measurement dimension. Optionally, the interference measurement value is used to indicate the average interference level or the highest interference level within the interference measurement range. In one example, the interference measurement value may be the average value or the maximum value measured within the interference measurement range. For example, taking the measurement dimension of the perception measurement as the distance measurement as an example, the interference measurement information includes the average amplitude value or the maximum amplitude value of the pulse compression result determined by the perception device within the interference measurement range. In another example, the perception device is capable of quantizing the interference measurement result (for example, the pulse compression result on the distance dimension) based on a predefined quantization rule, and the output interference measurement information includes the index of the quantized amplitude value of the pulse compression result.

[0120] For example, Figures 3A and 3B are examples of sensing measurements where the measurement dimension is angle measurement. In Figures 3A and 3B, the horizontal axis is the angle of the angular spectrum corresponding to the transmitting antenna array, and the vertical axis is the angle of the angular spectrum corresponding to the receiving antenna array. Position A in Figure 3A is the angular spectrum obtained after the interference signal is sensed and processed, and position B in Figure 3A is the angular spectrum obtained after the target signal is sensed and processed. The white framed area is the interference measurement range within the two-dimensional angular domain. As shown in Figure 3A, both the target signal and the interference signal have a large amplitude response in the two-dimensional angular domain after sensing and processing. Since the target signal and the interference signal do not overlap in the two-dimensional angular domain after sensing and processing, that is, the angular spectrum at position B does not overlap with the angular spectrum at position A, and even the angular spectrum at position A is not within the interference measurement range, the interference signal does not effectively interfere with the target signal. For the situation shown in Figure 3A, no interference suppression is required. As shown in Figure 3B, as the target signal changes, the position of the target signal in the two-dimensional angular domain after sensing and processing moves to position C, and the interference measurement range also changes with the movement of position C. After sensing and processing, the interference signal's position in the 2D angular domain (i.e., position A) is within the interference measurement range. After sensing and processing, the target signal and the interference signal nearly overlap in the 2D angular domain, i.e., position C and position A nearly overlap. At this point, the interference signal effectively interferes with the target signal, requiring interference suppression.

[0121] Optionally, the sensing device may determine at least one reference point within the interference measurement range. The sensing device may determine an interference measurement value at the location of the reference point based on the interference measurement signal. In this case, the interference measurement information output by the sensing device includes the interference measurement value at the location of the reference point.

[0122] For example, still using Figures 3A and 3B as an example, the white framed range represents the interference measurement range within the two-dimensional angular domain, and the white dots represent reference points. When calculating interference measurement values, the sensing device can only calculate the interference measurement values ​​for one or more reference points shown in Figures 3A or 3B, rather than necessarily for the entire interference measurement range, which helps to save computing overhead for the sensing device.

[0123] In this embodiment, since the first interference measurement resource for transmitting the interference measurement signal between the perception device and the interfering device is related to the measurement dimension of the perception measurement of the perception device, the interference measurement signal can reflect the interference of the interfering device on the perception device in the measurement dimension of the perception measurement, which is beneficial for the perception device to more accurately detect the impact of the interfering device on the perception device, and improve the accuracy of interference measurement in the perception scenario. In addition, the first interference measurement resource is also related to the interference measurement range, which is the effective measurement range of the perception measurement in the measurement dimension. It is beneficial for the perception device to determine whether it is affected by the interfering device within the interference measurement range, and it is beneficial to further improve the accuracy of interference measurement in the perception scenario.

[0124] An embodiment of the interference measurement method provided by the present application is described below in conjunction with FIG4. In this embodiment, the interference measurement is initiated by the sensing device, that is, the sensing device triggers negotiation with the interfering device to determine the first interference measurement resource. As shown in FIG4, the sensing device and the interfering device mainly perform the following steps:

[0125] Step 401: The sensing device determines at least one first candidate interference measurement resource based on a measurement dimension of a sensing measurement.

[0126] The first candidate interference measurement resource is a candidate resource used to determine the first interference measurement resource. Each of the at least one first candidate interference measurement resource is related to a measurement dimension of a perception measurement. For an explanation of the measurement dimension of the perception measurement and the first interference measurement resource, please refer to the relevant introduction in step 201 above and will not be repeated here.

[0127] In a possible implementation, the sensing device determines at least one first candidate interference measurement resource based on a measurement dimension of the sensing measurement and a constraint on a feature of the interference measurement resource corresponding to the measurement dimension.

[0128] Exemplarily, taking the measurement dimension as speed measurement as an example, the time domain characteristics of the interference measurement resource used to measure interference in the speed dimension are required to meet the constraints. For example, the constraint is that the duration of the interference measurement resource in the time domain is greater than the second threshold and / or the time domain repetition period is less than the third threshold. The sensing device determines at least one time-frequency resource that meets the aforementioned constraints as the first candidate interference measurement resource. The aforementioned constraints can be pre-configured in the sensing device or determined by the sensing device based on an algorithm, which is not limited by this application.

[0129] In another possible implementation, the sensing device determines at least one first candidate interference measurement resource based on a measurement dimension of the sensing measurement and a first correspondence. The first correspondence includes at least one measurement dimension and at least one interference measurement resource corresponding to each measurement dimension. This first correspondence may be specified by a protocol or preconfigured, and is not limited in this application.

[0130] For example, the first correspondence relationship may be as shown in the following Table 1-1:

[0131] Table 1-1

[0132] As shown in Table 1-1, if the perception measurement dimension is distance measurement, the perception device may determine resource 1 and / or resource 2 as the first candidate interference measurement resource based on the perception measurement dimension and the first correspondence. If the perception measurement dimension is speed measurement, the perception device may determine at least one of resource 3, resource 4, or resource 5 as the first candidate interference measurement resource based on the perception measurement dimension and the first correspondence. The remaining examples are similar and are not further described here.

[0133] Optionally, when the sensing device determines at least one first candidate interference measurement resource, the sensing device not only refers to the measurement dimension of the sensing measurement, but also refers to the interference measurement range or the sensing service type. For an explanation of the interference measurement range, please refer to the relevant introduction in step 201 above, which will not be repeated here. The following are introduced separately:

[0134] In one possible implementation, the sensing device determines at least one first candidate interference measurement resource based on a measurement dimension of a sensing measurement and an interference measurement range, wherein the measurement dimension of the sensing measurement is used to determine a constraint on a characteristic of the interference measurement resource corresponding to the measurement dimension, and the interference measurement range is used to determine a threshold for the constraint.

[0135] Exemplarily, if the measurement dimension of the perception measurement is speed measurement, the time domain characteristics of the interference measurement resource corresponding to the speed measurement dimension need to meet the constraint, for example, the constraint is that the time domain repetition period of the interference measurement resource is less than a certain threshold. In addition, the interference measurement range is used to determine the aforementioned threshold. For example, if the interference measurement range is -vm / s to +vm / s (v is a non-zero real number), the time domain repetition period of the interference measurement resource is less than λ / (2v) (where λ is the carrier wavelength), that is, the threshold is λ / (2v). Exemplarily, if the measurement dimension of the perception measurement is speed measurement, and the interference measurement range is -vm / s to +vm / s, the perception device selects at least one time-frequency resource from the time-frequency resources whose time domain repetition period is less than λ / (2v) as at least one first candidate interference measurement resource.

[0136] In another possible implementation, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement, the interference measurement range, the first correspondence, and the second correspondence. The first correspondence includes at least one measurement dimension and at least one interference measurement resource corresponding to each measurement dimension. The second correspondence includes at least one interference measurement range corresponding to the same measurement dimension and at least one interference measurement resource corresponding to each interference measurement range. The second correspondence may be specified by a protocol or preconfigured, and is not limited by this application.

[0137] For example, taking the measurement dimension of the perception measurement as speed measurement, the second corresponding relationship may be as shown in the following Table 2-1:

[0138] Table 2-1

[0139] Exemplarily, taking Table 1-1 and Table 2-1 as an example, if the measurement dimension of the perception measurement is speed measurement, the perception device determines that the interference measurement resources suitable for speed measurement include resource 3, resource 4 and resource 5 based on the measurement dimension and the first correspondence shown in Table 1-1. If the interference measurement range is 5m / s to 10m / s, the perception device determines that the interference measurement resource suitable for 5m / s to 10m / s is resource 4 based on the interference measurement range and the second correspondence shown in Table 2-1, that is, the perception device determines resource 4 as the first candidate interference measurement resource. It should be understood that Table 2-1 only shows the second correspondence when the measurement dimension is speed measurement. In actual applications, there are second correspondences for other measurement dimensions, and this application does not list examples one by one.

[0140] It should be understood that in actual applications, the interference measurement range known to the perception device may not completely overlap with the interference measurement range in the second corresponding relationship, but the perception device can still determine the first candidate interference measurement resource with reference to the second corresponding relationship. For example, the measurement dimension of the perception measurement is speed measurement, and the interference measurement range is 4m / s to 8m / s. The perception device determines the interference measurement resource with reference to the interference measurement range closest to 4m / s to 8m / s in the second corresponding relationship, that is, determines resource 4 as the first candidate interference measurement resource with reference to 5m / s to 10m / s.

[0141] In another possible implementation, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement, the sensing service type, the first correspondence, and the third correspondence. The first correspondence includes at least one measurement dimension and at least one interference measurement resource corresponding to each measurement dimension. The third correspondence includes at least one sensing service type corresponding to the same measurement dimension and at least one interference measurement resource corresponding to each sensing service type. The third correspondence may be specified by a protocol or preconfigured, and is not limited by this application.

[0142] For example, taking the measurement dimension of the perception measurement as speed measurement, the third corresponding relationship may be as shown in the following Table 3-1:

[0143] Table 3-1

[0144] Exemplarily, taking Table 1-1 and Table 3-1 as examples, if the measurement dimension of the perception measurement is speed measurement, the perception device determines that the interference measurement resources suitable for speed measurement include resource 3, resource 4, and resource 5 based on the measurement dimension and the first correspondence shown in Table 1-1. If the perception service type is to measure the speed of a non-motor vehicle, the perception device determines that the interference measurement resource suitable for measuring the speed of a non-motor vehicle is resource 3 based on the perception service type and the third correspondence shown in Table 3-1, that is, the perception device determines resource 3 as the first candidate interference measurement resource. It should be understood that Table 3-1 only shows the third correspondence when the measurement dimension is speed measurement. In actual applications, there are also third correspondences for other measurement dimensions, and this application does not list examples one by one.

[0145] It should be noted that step 401 is an optional step. For example, if at least one first candidate interference measurement resource is preconfigured in the sensing device, whenever the sensing device wants to perform measurement, the sensing device may not execute step 401 but directly trigger the execution of step 402.

[0146] Step 402: The sensing device sends a first interference measurement request; accordingly, the interfering device receives the first interference measurement request.

[0147] In one example, if the sensing device and the interfering device can communicate with each other, the sensing device sends a first interference measurement request to the interfering device; accordingly, the interfering device receives the first interference measurement request from the sensing device. For example, the sensing device and the interfering device are both access network devices (for example, TRP), and the first interference measurement request is transmitted between the sensing device and the interfering device via the Xn interface. For another example, the sensing device and the interfering device are both terminal devices, and the first interference measurement request is transmitted between the sensing device and the interfering device via the PC5 interface. For another example, the sensing device is a terminal device and the interfering device is an access network device; or, the sensing device is an access network device and the interfering device is a terminal device, then the first interference measurement request is transmitted between the sensing device and the interfering device via the Uu interface.

[0148] In another example, if the sensing device and the interfering device cannot communicate directly, the sensing device may forward the first interference measurement request to the interfering device through the coordination device; accordingly, the interfering device receives the first interference measurement request from the sensing device from the coordination device. For example, the sensing device and the interfering device are both terminal devices and do not support PC5 communication, the coordination device is an access network device, and the terminal device as the sensing device and the terminal device as the interfering device forward the first interference measurement request through the access network device. For another example, the sensing device and the interfering device are both access network devices, and there is no available communication interface between the sensing device and the interfering device, the coordination device is another access network device, and the coordination device communicates with the sensing device and the interfering device respectively through the Xn interface, and then the access network device as the sensing device and the access network device as the interfering device forward the first interference measurement request through the access network device as the coordination device.

[0149] It should be understood that the sensing device may send the first interference measurement request to one interfering device or to multiple interfering devices, and this application does not limit this. In addition, when the sensing device sends the first interference measurement request to multiple interfering devices, the sensing device may broadcast the first interference measurement request, which is beneficial to saving signaling overhead.

[0150] The first interference measurement request includes a measurement dimension of the sensing measurement and first resource indication information. The first resource indication information is used to indicate at least one first candidate interference measurement resource, that is, at least one first candidate interference measurement resource determined by the sensing device based on information such as the measurement dimension. After the interfering device receives the first interference measurement request, the interfering device can learn, based on the measurement dimension, that the first candidate interference measurement resource is associated with the measurement dimension.

[0151] Exemplarily, if the first interference measurement request includes information indicating distance measurement and information indicating resource 1 and resource 2, the interfering device learns based on the received first interference measurement request that the sensing device requests to measure interference in the distance measurement dimension, and expects the interfering device to send an interference measurement signal on resource 1 or resource 2.

[0152] Optionally, the first resource indication information may be an index of each first candidate interference measurement resource in the at least one first candidate interference measurement resource. For example, if the sensing device and the interfering device pre-agreed on the indexes of some resources through pre-configuration or signaling negotiation before executing step 402, the sensing device may indicate to the interfering device which resources are first candidate interference measurement resources through the resource indexes.

[0153] Optionally, the first interference measurement request further includes an interference measurement range, so that the interfering device takes the interference measurement range into consideration during a subsequent process of determining the first interference measurement resource.

[0154] Step 403: The interfering device determines a first interference measurement resource based on the measurement dimension of the sensing measurement and at least one first candidate interference measurement resource.

[0155] In one possible implementation, the interfering device selects a resource supported by the interfering device from at least one first candidate interference measurement resource as the first interference measurement resource, that is, the first interference measurement resource is a subset of the at least one first candidate interference measurement resource. For example, if the sensing device provides three first candidate interference measurement resources, namely 1 MHz 40 ms, 10 MHz 10 ms, and 20 MHz 5 ms, and if the interfering device only supports signaling on a 10 MHz resource, the interfering device determines 10 MHz 10 ms as the first interference measurement resource.

[0156] Optionally, the interference device may also refer to the measurement dimension and determine, from at least one first candidate interference measurement resource, a resource supported by the interference device and suitable for interference measurement in the measurement dimension as the first interference measurement resource. For example, if the sensing device provides four first candidate interference measurement resources for interference measurement in the distance measurement dimension, namely 1MHz 40ms, 10MHz 10ms, 10MHz 40ms and 20MHz 5ms. If the interference device only supports signaling on 10MHz resources, and 10MHz 10ms is more suitable for measuring interference in the distance measurement dimension than 10MHz 40ms, the interference device determines 10MHz 10ms as the first interference measurement resource.

[0157] Optionally, if the first interference measurement request includes an interference measurement range, the interference device may also refer to the interference measurement range when determining the first interference measurement resource. For example, if the sensing device provides 5 first candidate interference measurement resources for interference measurement in the distance measurement dimension, they are 1MHz 40ms, 10MHz 10ms, 10MHz 15ms, 10MHz 40ms and 20MHz 5ms. If the interference device only supports signaling on 10MHz resources, and both 10MHz 10ms and 10MHz 15ms are more suitable for measuring interference in the distance measurement dimension, the interference device selects the resource that is more likely to interfere with the interference measurement range in the distance measurement dimension from 10MHz 10ms and 10MHz 15ms as the first interference measurement resource.

[0158] It should be noted that the first interference measurement resource determined by the interfering device may not belong to the at least one first candidate interference measurement resource provided by the sensing device. For example, the sensing device may not be clear about the capabilities of the interfering device, resulting in no resources that can be used by the interfering device in the at least one first candidate interference measurement resource provided by the sensing device, or no resources that are applicable to the measurement dimension and supported by the interfering device. In this case, the interfering device determines the first interference measurement resource based on the measurement dimension of the sensing measurement and the resources supported by the interfering device. At this time, the first interference measurement resource determined by the interfering device may partially overlap or completely not overlap with a certain first candidate interference measurement resource provided by the sensing device in the time domain, frequency domain or spatial domain, and this application is not limited.

[0159] In a possible implementation, if the interfering device fails to determine a suitable resource as the first interference measurement resource from at least one first candidate interference measurement resource, the interfering device determines the first interference measurement resource based on constraints on a measurement dimension of the perceived measurement and a characteristic of the interference measurement resource corresponding to the measurement dimension.

[0160] Exemplarily, taking the measurement dimension as speed measurement as an example, the time domain characteristics of the interference measurement resource used to measure interference in the speed dimension are required to meet the constraints. For example, the constraint is that the duration of the interference measurement resource in the time domain is greater than the second threshold and / or the time domain repetition period is less than the third threshold. The interfering device determines at least one time-frequency resource that meets the aforementioned constraints and is supported by the interfering device as the first interference measurement resource. The aforementioned constraints can be pre-configured in the interfering device or determined by the interfering device based on an algorithm, which is not limited in this application.

[0161] In another possible implementation, if the interfering device does not determine a suitable resource as the first interference measurement resource from at least one first candidate interference measurement resource, and the first interference measurement request includes an interference measurement range, the interfering device further determines the first interference measurement resource based on a measurement dimension of a perception measurement and the interference measurement range. The measurement dimension of the perception measurement is used to determine a constraint on a characteristic of the interference measurement resource corresponding to the measurement dimension, and the interference measurement range is used to determine a threshold value for the constraint.

[0162] Exemplarily, if the measurement dimension of the perception measurement is speed measurement, the time domain characteristics of the interference measurement resource corresponding to the speed measurement dimension need to meet the constraint, for example, the constraint is that the time domain repetition period of the interference measurement resource is less than a certain threshold. In addition, the interference measurement range is used to determine the aforementioned threshold. For example, the interference measurement range is -vm / s to +vm / s (v is a non-zero real number), then the time domain repetition period of the interference measurement resource is less than λ / (2v) (where λ is the carrier wavelength), that is, the threshold is λ / (2v). Exemplarily, if the measurement dimension of the perception measurement is speed measurement, and the interference measurement range is -vm / s to +vm / s, the interference device selects at least one time-frequency resource supported by the interference device from the time-frequency resources with a time domain repetition period less than λ / (2v) as the first interference measurement resource.

[0163] In this step, the interfering device preferentially screens the first interference measurement resource from at least one first candidate interference measurement resource provided by the sensing device. Since the at least one first candidate interference measurement resource provided by the sensing device is related to the measurement dimension of the sensing measurement, the interfering device only needs to screen the resources supported by the interfering device from the at least one first candidate interference measurement resource as the first interference measurement resource, which is beneficial to reducing the complexity of the interfering device in determining the first interference measurement resource and saving the processing overhead of the interfering device. In addition, when the interfering device fails to determine the first interference measurement resource from at least one first candidate interference measurement resource, the interfering device can determine the first interference measurement resource based on the measurement dimension (and interference measurement range) of the sensing measurement, which is beneficial to ensure the reliability of the interfering device in determining the first interference resource.

[0164] It should be noted that step 403 is an optional step. For example, if the interfering device does not participate in interference measurement, the interfering device does not perform step 403; if the interfering device participates in interference measurement, the interfering device performs step 403.

[0165] Step 404: The interfering device sends a first interference measurement response; accordingly, the sensing device receives the first interference measurement response.

[0166] Among them, the first interference measurement response is used to indicate whether the interfering device participates in the interference measurement. For example, the first interference measurement response includes first indication information, one value of the first indication information indicates that the interfering device participates in the interference measurement, and another value of the first indication information indicates that the interfering device does not participate in the measurement. It should be understood that if the first interference measurement response indicates that the interfering device does not participate in the interference measurement, the interfering device and the perception device do not perform subsequent steps 405 to 406; if the first interference measurement response indicates that the interfering device participates in the interference measurement, the interfering device and the perception device perform subsequent steps 405 to 406, and the first interference measurement response includes second resource indication information, and the second resource indication information is used to indicate the first interference measurement resource.

[0167] In step 405 , the interfering device sends an interference measurement signal through the first interference measurement resource; correspondingly, the sensing device receives the interference measurement signal sent by the interfering device through the first interference measurement resource.

[0168] Step 406: The sensing device determines interference measurement information based on the interference measurement signal.

[0169] In this embodiment, steps 405 to 406 are similar to steps 202 to 203 above. For details, please refer to the relevant descriptions in steps 202 to 203 above, which will not be repeated here.

[0170] In this embodiment, since the perception device provides the interference device with the measurement dimension of the perception measurement and at least one first candidate interference measurement resource, the interference device determines the first interference measurement resource based on the measurement dimension of the perception measurement and the at least one first candidate interference measurement resource. Since the first interference measurement resource finally determined for transmitting the interference measurement signal is related to the measurement dimension of the perception measurement of the perception device, the interference measurement signal can reflect the interference of the interference device on the perception device in the measurement dimension of the perception measurement, which is beneficial for the perception device to more accurately detect the impact of the interference device on the perception device and improve the accuracy of interference measurement in the perception scenario. In addition, the perception device triggers negotiation with the interference device to determine the first interference measurement resource, which is beneficial for the perception device to initiate interference measurement when interference management is required, thereby enabling the perception device to perform interference measurement on demand and improve the flexibility of interference measurement.

[0171] Another embodiment of the interference measurement method provided by the present application is described below in conjunction with FIG5 . In this embodiment, the interference measurement is initiated by the interfering device, that is, the interfering device triggers a negotiation with the sensing device to determine the first interference measurement resource. As shown in FIG5 , the sensing device and the interfering device mainly perform the following steps:

[0172] Step 501: The interfering device sends a second interference measurement request; correspondingly, the sensing device receives the second interference measurement request.

[0173] In one example, if the interfering device and the perception device can communicate, the interfering device sends a second interference measurement request to the perception device; accordingly, the perception device receives the second interference measurement request from the interfering device. For example, the interfering device and the perception device are both access network devices (e.g., TRP), and the second interference measurement request is transmitted between the interfering device and the perception device via the Xn interface. For another example, the interfering device and the perception device are both terminal devices, and the second interference measurement request is transmitted between the interfering device and the perception device via the PC5 interface. For another example, the interfering device is a terminal device and the perception device is an access network device; or, the interfering device is an access network device and the perception device is a terminal device, then the second interference measurement request is transmitted between the interfering device and the perception device via the Uu interface.

[0174] In another example, if the interfering device and the perception device cannot communicate directly, the interfering device may forward the second interference measurement request to the perception device through the coordination device; accordingly, the perception device receives the second interference measurement request from the interfering device from the coordination device. For example, the interfering device and the perception device are both terminal devices and do not support PC5 communication, the coordination device is an access network device, and the terminal device serving as the interfering device and the terminal device serving as the perception device forward the second interference measurement request through the access network device. For another example, the interfering device and the perception device are both access network devices, and there is no available communication interface between the interfering device and the perception device, the coordination device is another access network device, and the coordination device communicates with the perception device and the interfering device respectively through the Xn interface, and then the access network device serving as the interfering device and the access network device serving as the perception device forward the second interference measurement request through the access network device serving as the coordination device.

[0175] In addition, the interfering device may send a second interference measurement request to one sensing device, or may send a second interference measurement request to multiple sensing devices, which is not limited in this application. When the interfering device sends a second interference measurement resource to multiple sensing devices, the interfering device may broadcast the second interference measurement resource. For example, the interfering device periodically broadcasts a second interference measurement request to request the surrounding sensing devices to cooperate in interference measurement, so that the surrounding sensing devices update the interference situation. The interfering device notifies the sensing devices in batches in a broadcast mode to perform interference measurement, which is conducive to improving the efficiency of interference measurement.

[0176] The second interference measurement request includes third resource indication information, where the third resource indication information is used to indicate at least one second candidate interference measurement resource supported by the interfering device. The second candidate interference measurement resource is a resource supported by the interfering device, that is, the interfering device can send a working signal or a signal dedicated to interference measurement on the second candidate interference measurement resource.

[0177] Optionally, the second candidate interference measurement resource is related to a measurement dimension of the perception measurement. The second interference measurement request includes third resource indication information and a measurement dimension related to the second candidate interference measurement resource.

[0178] In one possible implementation, at least one second candidate interference measurement resource is associated with the same measurement dimension. For example, each second candidate interference measurement resource in the at least one second candidate interference measurement resource is associated with distance measurement. For another example, each second candidate interference measurement resource in the at least one second candidate interference measurement resource is associated with speed measurement. For another example, each second candidate interference measurement resource in the at least one second candidate interference measurement resource is associated with angle measurement. For another example, each second candidate interference measurement resource in the at least one second candidate interference measurement resource is associated with imaging measurement.

[0179] Optionally, the interfering device may send a second interference measurement request multiple times, the second candidate interference measurement resource included in the second interference measurement request sent at the same time is related to one measurement dimension, and the second candidate interference measurement resources included in the second interference measurement request sent at different times are related to different measurement dimensions. For example, the interfering device broadcasts the second interference measurement request at a certain interval, the second candidate interference measurement resource included in the second interference measurement request broadcast by the interfering device at the first moment is related to distance measurement, the second candidate interference measurement resource included in the second interference measurement request broadcast by the interfering device at the second moment is related to speed measurement, the second candidate interference measurement resource included in the second interference measurement request broadcast by the interfering device at the third moment is related to angle measurement, etc.

[0180] In this embodiment, the second candidate interference measurement resource provided by the interfering device to the sensing device takes into account not only the capabilities of the interfering device but also the measurement dimension of the sensing measurement. This is beneficial for providing the sensing device with more accurate candidate interference measurement resources applicable to a certain measurement dimension, and is also beneficial for the sensing device to more quickly determine the first interference measurement resource applicable to a certain measurement dimension, thereby improving the efficiency of interference measurement. In addition, for the second candidate interference measurement resources of different measurement dimensions, the interfering device carries them in different second interference measurement requests and sends them, which can provide different second candidate interference measurement resources for different measurement dimensions for selection by the sensing device, which is beneficial for the sensing device to measure interference in different measurement dimensions and improve the diversity of interference measurement.

[0181] In another possible implementation, different second candidate interference measurement resources in at least one second candidate interference measurement resource are associated with different measurement dimensions. For example, the third resource indication information included in the second interference measurement request indicates three second candidate interference measurement resources, one second candidate interference measurement resource is associated with distance measurement, another second candidate interference measurement resource is associated with speed measurement, and another second candidate interference measurement resource is associated with angle measurement. In this example, the second interference measurement request includes three second candidate interference measurement resources and the measurement dimension associated with each second candidate interference measurement resource.

[0182] In this embodiment, the interfering device can provide a plurality of second candidate interference measurement resources to the sensing device through a second interference measurement request, and the plurality of candidate interference measurement resources are respectively applicable to a plurality of measurement dimensions. This is beneficial for the sensing device to obtain the second candidate interference measurement resources for different measurement dimensions through less signaling, so that the sensing device can subsequently initiate interference measurements for other measurement dimensions, which is beneficial to saving signaling overhead. For example, if the sensing device needs to perform interference measurement for the distance measurement dimension in the first time period and needs to perform interference measurement for the speed measurement dimension in the second time period, and the third resource indication information received by the sensing device indicates a candidate interference measurement resource 1 related to the distance measurement and a candidate interference measurement resource 2 related to the speed measurement, the sensing device can use the candidate interference measurement resource 1 for the current interference measurement for the distance measurement dimension, and use the candidate interference measurement resource 2 for the subsequent interference measurement for the speed measurement dimension. Therefore, it is beneficial to save signaling overhead.

[0183] Step 502: The sensing device determines a first interference measurement resource based on a measurement dimension of the sensing measurement and at least one second candidate interference measurement resource.

[0184] The measurement dimension of the perception measurement is the measurement dimension of the perception measurement being performed by the perception device, or the measurement dimension of the perception measurement that is about to be started by the perception device.

[0185] Specifically, the sensing device selects a resource suitable for performing interference measurement in the measurement dimension from at least one second candidate interference measurement resource and determines it as a first interference measurement resource. The first interference measurement resource is a subset of the at least one second candidate interference measurement resource.

[0186] In a possible implementation, the sensing device determines the first interference measurement resource from at least one second candidate interference measurement resource based on a measurement dimension of the sensing measurement and a constraint on a feature of the interference measurement resource corresponding to the measurement dimension.

[0187] Exemplarily, taking the measurement dimension as speed measurement as an example, the time domain characteristics of the interference measurement resource used to measure interference in the speed dimension are required to meet the constraints. For example, the constraint is that the duration of the interference measurement resource in the time domain is greater than the second threshold and / or the time domain repetition period is less than the third threshold. The sensing device selects a resource that meets the aforementioned constraints from at least one second candidate interference measurement resource as the first interference measurement resource. The aforementioned constraints may be pre-configured in the sensing device or determined by the sensing device based on an algorithm, which is not limited by this application.

[0188] In another possible implementation, the sensing device determines the first interference measurement resource from at least one second candidate interference measurement resource based on the measurement dimension of the sensing measurement and the first correspondence. For an explanation of the first correspondence, please refer to the relevant introduction in step 401 above and will not be repeated here.

[0189] For example, taking Table 1-1 described above as an example, if the perception measurement dimension is a distance measurement, the perception device can determine, based on the perception measurement dimension and the first correspondence, that the resources corresponding to the measurement dimension are resource 1 and resource 2. If resource 1 belongs to the second candidate interference measurement resource, for example, resource 1 overlaps or partially overlaps with a second candidate interference measurement resource, the perception device determines resource 1 as the first interference measurement resource.

[0190] Optionally, when the sensing device determines the first interference measurement resource, the sensing device not only refers to the measurement dimension of the sensing measurement, but also refers to the interference measurement range or the sensing service type. The following are respectively introduced:

[0191] In a possible implementation, the sensing device determines the first interference measurement resource from at least one second candidate interference measurement resource based on a measurement dimension and an interference measurement range of the sensing measurement.

[0192] The measurement dimension of the sensing measurement is used to determine a characteristic constraint of the interference measurement resource corresponding to the measurement dimension, and the interference measurement range is used to determine a threshold value of the characteristic constraint. The sensing device determines, from at least one second candidate interference measurement resource, a resource that satisfies the characteristic constraint of the interference measurement resource corresponding to the measurement dimension and reaches the threshold value of the constraint as a first interference measurement resource.

[0193] Exemplarily, if the measurement dimension of the perception measurement is speed measurement, the time domain characteristics of the interference measurement resource corresponding to the speed measurement dimension need to satisfy that the time domain repetition period is less than a certain threshold. In addition, the interference measurement range is used to determine the aforementioned threshold. For example, if the interference measurement range is -vm / s to +vm / s (v is a non-zero real number), the time domain repetition period of the interference measurement resource is less than λ / (2v) (where λ is the carrier wavelength), that is, the threshold is λ / (2v). Exemplarily, if the measurement dimension of the perception measurement is speed measurement, and the interference measurement range is -vm / s to +vm / s, the perception device selects a time-frequency resource with a time domain repetition period less than λ / (2v) from at least one second candidate interference measurement resource as the first interference measurement resource.

[0194] In another possible implementation, the sensing device determines the first interference measurement resource from at least one second candidate interference measurement resource based on the measurement dimension of the sensing measurement, the interference measurement range, the first correspondence, and the second correspondence. For an explanation of the first correspondence and the second correspondence, please refer to the relevant introduction in step 401 above and will not be repeated here.

[0195] For example, taking Table 1-1 and Table 2-1 described above as an example, if the perception measurement dimension is speed measurement, the perception device determines, based on the perception measurement dimension and the first correspondence shown in Table 1-1, that the interference measurement resources applicable to speed measurement include resource 3, resource 4, and resource 5. If the interference measurement range is 5 m / s to 10 m / s, the perception device determines, based on the interference measurement range and the second correspondence shown in Table 2-1, that the interference measurement resource applicable to 5 m / s to 10 m / s is resource 4. Then, the perception device determines, from at least one second candidate interference measurement resource, a second candidate interference measurement resource that overlaps or partially overlaps with resource 4 as the first interference measurement resource.

[0196] In another possible implementation, the sensing device determines the first interference measurement resource from at least one second candidate interference measurement resource based on the measurement dimension of the sensing measurement, the sensing service type, the first correspondence, and the third correspondence. For an explanation of the first correspondence and the third correspondence, please refer to the relevant introduction in step 401 above and will not be repeated here.

[0197] For example, using Tables 1-1 and 3-1 described above as an example, if the measurement dimension of the sensing measurement is speed measurement, the sensing device determines, based on the measurement dimension and the first correspondence shown in Table 1-1, that the interference measurement resources suitable for speed measurement include Resource 3, Resource 4, and Resource 5. If the sensing service type is measuring the speed of a non-motor vehicle, the sensing device determines, based on the sensing service type and the third correspondence shown in Table 3-1, that the interference measurement resource suitable for measuring the speed of a non-motor vehicle is Resource 3. The sensing device then determines, from at least one second candidate interference measurement resource, a second candidate interference measurement resource that overlaps or partially overlaps with Resource 3 as the first interference measurement resource.

[0198] It should be understood that if the sensing device fails to select the first interference measurement resource from the at least one second candidate interference measurement resource, the sensing device does not participate in the interference measurement.

[0199] It should be noted that step 502 is an optional step. For example, if the sensing device does not participate in interference measurement, the sensing device does not perform step 502; if the sensing device participates in interference measurement, the sensing device performs step 502.

[0200] Step 503: The sensing device sends a second interference measurement response; correspondingly, the interfering device receives the second interference measurement response.

[0201] The second interference measurement response includes fourth resource indication information, and the fourth resource indication information is used to indicate the first interference measurement resource.

[0202] Among them, the second interference measurement response is used to indicate whether the perception device participates in the interference measurement. For example, the second interference measurement response includes second indication information, one value of the second indication information indicates that the perception device participates in the interference measurement, and another value of the second indication information indicates that the perception device does not participate in the measurement. It should be understood that if the second interference measurement response indicates that the perception device does not participate in the interference measurement, the interfering device and the perception device do not perform subsequent steps 504 to 505; if the second interference measurement response indicates that the perception device participates in the interference measurement, the interfering device and the perception device perform subsequent steps 504 to 505, and the second interference measurement response includes fourth resource indication information, and the fourth resource indication information is used to indicate the first interference measurement resource.

[0203] Step 504: The interfering device sends an interference measurement signal through the first interference measurement resource; correspondingly, the sensing device receives the interference measurement signal sent by the interfering device through the first interference measurement resource.

[0204] Step 505: The sensing device determines interference measurement information based on the interference measurement signal.

[0205] In this embodiment, steps 504 to 505 are similar to steps 202 to 203 above. Please refer to the relevant descriptions in steps 202 to 203 above for details, which will not be repeated here.

[0206] In this embodiment, since the interference device provides at least one second candidate interference measurement resource to the perception device, the perception device determines the first interference measurement resource based on the measurement dimension of the perception measurement and the at least one second candidate interference measurement resource. Since the first interference measurement resource finally determined for transmitting the interference measurement signal is related to the measurement dimension of the perception measurement of the perception device, the interference measurement signal can reflect the interference of the interference device on the perception device in the measurement dimension of the perception measurement, which is conducive to the perception device to more accurately detect the impact of the interference device on the perception device and improve the efficiency of interference measurement in the perception scenario. In addition, the interference device triggers the negotiation with the perception device to determine the first interference measurement resource, which can realize the active triggering of interference management by the interference device in the scenario with fewer interference devices, thereby improving the efficiency of interference management.

[0207] In addition, after the sensing device obtains the interference measurement information, the sensing device will perform interference management based on the interference measurement information. As shown in FIG6 , the sensing device and the interfering device may further perform the following steps:

[0208] Step 601: The sensing device determines parameters of a sensing signal and / or sensing measurement resources occupied by the sensing signal based on interference measurement information.

[0209] Among them, the perception signal is a measurement signal sent by the perception device when performing perception measurement. The perception measurement resource is used to send the aforementioned perception signal. Exemplarily, the perception signal can be a reference signal already defined in existing communications, such as a channel state information reference signal (CSI-RS), a demodulation reference signal (DM-RS), a positioning reference signal (PRS), or a redefined continuous wave (CW) signal, a frequency modulated continuous wave (FMCW) signal, a linear frequency modulation (LFM) signal, a phase modulated continuous wave (PMCW) signal, an orthogonal frequency division multiplexing (OFDM) signal, etc.

[0210] Because the sensing device can determine the interference level of the interfering device on the sensing device based on the interference measurement information, in order to reduce the impact of the interfering device on the sensing device, the sensing device refers to the interference measurement information to determine the sensing signal sent by the sensing device in subsequent sensing measurement processes. Specifically, the sensing device determines the parameters of the sensing signal and / or the sensing measurement resources occupied by the sensing signal based on the interference measurement information. The parameters of the sensing signal include at least one of signal power, signal phase, or signal amplitude; and the sensing measurement resources include at least one of time domain resources, frequency domain resources, or port resources.

[0211] In a possible implementation, the sensing device determines parameters of the sensing signal based on the interference measurement information, and configures specific parameters to minimize interference to the sensing signal in the measurement dimension.

[0212] In one example, the difference between the power of the perception signal determined by the perception device and the signal power of the interference measurement signal is greater than a preset threshold. For example, if the perception device determines, based on the interference measurement information, that the power of the interference measurement signal is -30 dBm and the preset power threshold is 80 dBm, the perception device determines the power of the perception signal to be -30 dBm + 80 dBm, i.e., 50 dBm.

[0213] In another example, the waveform of the perception signal determined by the perception device is orthogonal to the waveform of the interference measurement signal, so that the perception signal and the interference measurement signal do not interfere with each other in the measurement dimension. For example, when the perception device and the interference device both use FMCW waveforms, and at the same time, the frequency f1 of the FMCW waveform of the perception device and the frequency f2 of the FMCW waveform of the interference device are close, the interference device may interfere with the perception device. In order to avoid interference, the perception device can adjust the FMCW waveform it uses so that the difference between the frequency of the FMCW waveform it uses and the frequency of the FMCW waveform used by the interference device meets the preset threshold at any time. For another example, when the perception device and the interference device both use PMCW waveforms, in order to avoid interference, the perception device can adjust the phase sequence used to generate the PMCW waveform so that the cross-correlation between the PMCW waveform of the perception device and the PMCW waveform of the interference device is reduced to below the threshold value.

[0214] In another possible implementation, the sensing device determines the sensing measurement resources occupied by the sensing signal based on the interference measurement information, that is, the sensing measurement resources used by the sensing device to send the sensing signal during the sensing measurement process.

[0215] In one example, the sensing measurement resource occupied by the sensing signal determined by the sensing device does not overlap with the first interference measurement resource. Since the sensing measurement resource does not overlap with the first interference measurement resource, the sensing device is not interfered with by the interfering device.

[0216] In another example, the sensing measurement resource occupied by the sensing signal determined by the sensing device overlaps or partially overlaps with the first interference measurement resource, so that the sensing measurement in the measurement dimension is not affected by the signal sent by the first interference measurement resource.

[0217] Optionally, after the sensing device executes step 601, the sensing device may further execute step 603, and the interfering device may further execute step 603. If, after the sensing device executes step 601, the interference of the interfering device on the sensing device is reduced to a level that hardly affects the sensing measurement, the sensing device may not execute step 602, and thus does not trigger the interfering device to execute step 603.

[0218] Step 602: The sensing device sends first information; correspondingly, the interfering device receives the first information.

[0219] Optionally, if the interference level indicated by the interference measurement information is greater than a first threshold, the sensing device sends a first message to the interfering device. The first threshold is a critical value that triggers the sensing device to notify the interfering device to adjust the interference signal. It can be understood that the first threshold is the maximum interference that the sensing device can tolerate. For example, when the interference level experienced by the sensing device is greater than the first threshold, the sensing measurement service of the sensing device may not function properly.

[0220] It should be understood that the first threshold can be a threshold for peak interference or a threshold for average interference, and this application does not limit it. For example, if the interference measurement information is the average power of the interference measurement signal in the measurement dimension after perception processing, the first threshold is the threshold for average power (i.e., the threshold for average interference). For another example, if the interference measurement signal has a peak power in the measurement dimension after perception processing, the first threshold is the threshold for peak power (i.e., the threshold for peak interference). For another example, if the ratio of the power of the interference measurement signal after perception processing to the preset power is greater than or equal to the power of the preset power, the first threshold is the threshold for the ratio.

[0221] Optionally, the first threshold is related to a measurement dimension of the perception measurement.

[0222] Optionally, the first information is used to instruct the interference device to adjust the parameters of the interference measurement signal and / or the resources occupied by the interference measurement signal; wherein the parameters of the interference measurement signal include at least one of signal power, signal phase or signal amplitude; and the resources include at least one of time domain resources, frequency domain resources or port resources.

[0223] In addition, the first information can be implemented in multiple ways, which are introduced below:

[0224] In one possible implementation, the first information includes an interference measurement report, which includes a measurement dimension of the sensing measurement, interference measurement information, and a second threshold. The second threshold is the level of interference that the sensing device expects to achieve. It can be understood that the second threshold is used to indicate the level to which the sensing device expects interference to be controlled during normal operation. It can also be understood that the second threshold is used to indicate the level to which the sensing device recommends the interfering device reduce interference. Optionally, the second threshold is less than or equal to the first threshold.

[0225] In this embodiment, in order to reduce the interference caused by the interfering device to the sensing device, the sensing device, in addition to providing interference measurement information and measurement dimensions to the interfering device, also provides a reference value (i.e., the second threshold) for recommending the interfering device to lower the interference measurement signal to a certain extent, which is conducive to the interfering device to quickly and effectively adjust the interference and improve the efficiency and accuracy of interference management.

[0226] In another possible implementation, the first information includes at least one adjustment instruction, each adjustment instruction being used to instruct the interfering device to adjust a parameter of the interference measurement signal, wherein the parameter includes at least one of signal power, signal phase, or signal amplitude.

[0227] In this embodiment, the sensing device directly provides the interference device with an adjustment instruction for adjusting the interference measurement signal, and the interference device only needs to adjust the parameters of the interference measurement signal according to the adjustment instruction, which helps to save the processing overhead of the interference device for calculating the adjusted parameters.

[0228] Optionally, the adjustment instruction may indicate an adjustment range of the interference measurement parameter. For example, taking power adjustment as an example, the adjustment instruction included in the first information is 10 dB, instructing the interfering device to reduce the power of the interference measurement signal by 10 dB.

[0229] Step 603: The interfering device adjusts parameters of the interference measurement signal and / or resources occupied by the interference measurement signal based on the first information.

[0230] In one embodiment, the first information includes an interference measurement report, and the interference measurement report includes a measurement dimension of the perception measurement, interference measurement information, and a second threshold. The interference measurement information can reflect the current interference level of the perception device, and the second threshold indicates the interference level expected by the perception device. The interference device adjusts the signal power of the interference measurement signal based on the second threshold so that the interference level of the adjusted interference measurement signal on the perception device is less than or equal to the second threshold. For example, the power of the interference measurement signal before adjustment is 40dBm, and the average power of the interference measurement signal in the measurement dimension after perception processing is -60dBm, and the second threshold is -80dBm. The interference device determines that the power of the adjusted interference measurement signal is 40dBm-(-60dBm+80dBm), that is, 20dBm, and the average power of the adjusted interference measurement signal in the measurement dimension after perception processing is -80dBm.

[0231] In another embodiment, the first information includes at least one adjustment instruction, each adjustment instruction being used to instruct the interfering device to adjust a parameter of the interference measurement signal. The interfering device adjusts the interference measurement signal based on the at least one adjustment instruction. For example, using power adjustment as an example, if the adjustment instruction included in the first information is 10 dB, the interfering device lowers the power of the interference measurement signal by 10 dB.

[0232] In this embodiment, after the sensing device determines the interference measurement information, the sensing device can determine a sensing signal based on the interference measurement information, or instruct the interfering device to adjust the interference measurement signal through the first information. Therefore, by adjusting the sensing signal or the interference measurement signal, the interference of the interfering device in the measurement dimension of the sensing measurement can be reduced, thereby more effectively mitigating or eliminating the sensing interference.

[0233] Corresponding to the scheme given in the above method embodiment, the embodiment of the present application also provides a corresponding device (e.g., a communication device) and a communication system, wherein the device includes a module or unit for executing each part of the above embodiment. The module or unit can be software, hardware, or a combination of software and hardware. The following is only a brief description of the device and system. For the implementation details of the scheme, reference can be made to the description of the above method embodiment, which will not be repeated below.

[0234] As shown in Figure 7, Figure 7 is a structural diagram of a device 70 provided in an embodiment of the present application. The specific implementation of the perception device or interference device in the flowchart shown in Figures 2, 4, 5 or 6 can refer to the internal structure of the device 70 shown in Figure 7. When the device 70 is used to implement the function of the perception device in the method shown in Figures 2, 4, 5 or 6, the device 70 can be an access network device, a terminal device or other device or apparatus capable of realizing the perception measurement function through wireless signals. When the device 70 is used to implement the function of the interference device in the method shown in Figures 2, 4, 5 or 6, the device 70 can be an access network device, a terminal device or other device capable of transmitting wireless signals that may cause interference to other communication devices.

[0235] As shown in Figure 7, the device 70 may include a processor 701 and a transceiver 702, with the processor 701 coupled to the transceiver 702. The processor 701 may be a baseband processor or a central processing unit (CPU), and the baseband processor and CPU may be integrated or separate.
