Description

Technical Field

[0001] Embodiments of the present application relate to the field of communications, and in particular, to an interference measurement method and related devices. Background Art

[0002] The reason for the formation of interference in communications is that the communication signals of different users overlap in the time domain, frequency domain, or spatial domain, resulting in mutual influence of different communication signals and ultimately reducing communication performance. To improve communication performance, a communication device needs to perform interference measurement to obtain an interference measurement result, and then perform processing such as communication link management, channel estimation, and data demodulation based on the interference measurement result.

[0003] Similar to the interference in communications, there may also be interference in the sensing scenario. For example, there may be mutual influence between other signals and the sensing signal in the sensing measurement, ultimately reducing the sensing performance. To improve the sensing performance, interference management such as interference measurement is also required.

[0004] However, the interference measurement in traditional technologies is performed on the time-frequency resource grid defined in communications. In the sensing scenario, when the time-frequency resources occupied by the interference signal overlap with the time-frequency resources occupied by the sensing measurement, it may not affect the sensing measurement. Therefore, the interference measurement resources in traditional technologies may not be applicable to measure the interference level in the sensing scenario. Summary of the Invention

[0005] The present application provides an interference measurement method and related devices for measuring the interference level on sensing in the sensing scenario and improving the accuracy of interference measurement in the sensing scenario.

[0006] In a first aspect, the present application provides an interference measurement method. This interference measurement method can be executed by a sensing device or by components of the sensing device (such as components like a processor, a chip, or a chip system, etc.). Taking the sensing device as an example, before or during the sensing measurement, the sensing device acquires a first interference measurement resource, and the first interference measurement resource is related to the measurement dimension of the sensing measurement of the sensing device; then, the sensing device receives an interference measurement signal sent by an interference device through the first interference measurement resource.

[0007] In the present application, since the first interference measurement resource for transmitting the interference measurement signal between the sensing device and the interference device is related to the measurement dimension of the sensing measurement of the sensing device, the interference measurement signal can reflect the interference situation of the interference device on the sensing device in the measurement dimension of the sensing measurement, which is beneficial for the sensing device to more accurately detect the influence of the interference device on the sensing device and improve the accuracy of interference measurement in the sensing scenario.

[0008] 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 sensing measurement in the measurement dimension. Optionally, the interference measurement range is used to indicate the range within which the sensing measurement cannot tolerate interference. It can be understood that when the projection of the interference measurement signal in this measurement dimension after sensing processing falls within this interference measurement range, the interference measurement signal will interfere with the sensing measurement; when the projection of the interference measurement signal in this measurement dimension after sensing processing does not fall within this interference measurement range, the interference measurement signal will not interfere with the sensing measurement. This is beneficial for the sensing device to determine whether it is affected by the interfering device within this interference measurement range, and is beneficial for further improving the accuracy of interference measurement in the sensing scenario.

[0009] In a possible implementation, the interference measurement method further includes: the sensing device determines interference measurement information based on the interference measurement signal, and the interference measurement information is used to indicate the interference situation of the interference measurement signal on the sensing device in the sensing measurement dimension.

[0010] In this implementation, the sensing device determines the interference measurement information based on the received interference measurement signal, and quantifies the interference received by the sensing device into a specific value, which is beneficial for intuitively reflecting the interference received by the sensing device and facilitating subsequent interference management.

[0011] In a possible implementation, the interference measurement information includes the interference measurement value of the interference measurement signal in the measurement dimension. Optionally, the interference measurement information includes the interference measurement value of the interference measurement signal within the interference measurement range in the measurement dimension.

[0012] 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 for improving the accuracy and efficiency of subsequent interference management.

[0013] In a possible implementation, for the sensing device to obtain the first interference measurement resource, it includes: the sensing device sends a first interference measurement request, and the first interference measurement request includes the measurement dimension of the sensing measurement and the first resource indication information, where the first resource indication information is used to indicate at least one first candidate interference measurement resource, and 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, and the first interference measurement response includes second resource indication information, where the second resource indication information is used to indicate the first interference measurement resource. Among them, the first interference measurement resource is determined based on at least one first candidate interference measurement resource.

[0014] In this embodiment, the sensing device triggers negotiation with the interference device to determine the first interference measurement resource, which is beneficial for the sensing device to initiate interference measurement when interference management is required, so as to enable the sensing device to perform interference measurement on demand and improve the flexibility of interference measurement. In addition, the first interference measurement request includes the measurement dimension of the sensing measurement, which is beneficial for the interference device to consider the measurement dimension of the sensing measurement when determining the first interference measurement resource, so that the interference device can determine a resource more suitable for measuring the interference of this measurement dimension, thereby improving the accuracy of interference measurement.

[0015] Optionally, the first interference measurement request further includes an interference measurement range, and the first candidate interference measurement resource is related to the interference measurement range. This is beneficial for the interference device to consider the interference measurement range when determining the first interference measurement resource, so that the interference device can determine a resource more suitable for measuring the interference of this measurement dimension, thereby improving the accuracy of interference measurement.

[0016] In a possible implementation manner, the interference measurement method further includes: the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement and the 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 can be specified by a protocol or pre-configured, and the present application does not limit this.

[0017] In this embodiment, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension and the first correspondence, which is beneficial for improving the efficiency of determining the first candidate interference measurement resource and saving the processing overhead of the sensing device.

[0018] In a possible implementation manner, the interference measurement method further includes: the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement and the interference measurement range.

[0019] In this embodiment, since the sensing device considers the measurement dimension of the sensing measurement and the interference measurement range when determining the first candidate interference measurement resource, it is beneficial for the sensing device to determine a candidate resource suitable for measuring interference measurement, thereby improving the accuracy of interference measurement.

[0020] In a possible implementation manner, the sensing device obtains the first interference measurement resource, including: the sensing device receives a second interference measurement request, where the second interference measurement request includes third resource indication information for indicating at least one second candidate interference measurement resource supported by the interference device; the sensing device sends a second interference measurement response, where the second interference measurement response includes fourth resource indication information for indicating the first interference measurement resource. Among them, the first interference measurement resource is determined based on at least one second candidate interference measurement resource.

[0021] In this embodiment, the interference device triggers the negotiation with the sensing device to determine the first interference measurement resource, which can realize the active triggering of interference management by the interference device in a scenario with fewer interference devices, thereby improving the efficiency of interference management.

[0022] In a possible implementation, the interference measurement method further includes: 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.

[0023] In this embodiment, the process of the sensing 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 sensing measurement, so that the sensing device can determine a resource that is more suitable for measuring the interference of this measurement dimension, thereby improving the accuracy of interference measurement.

[0024] 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.

[0025] In this embodiment, the process of the sensing 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 sensing measurement and the interference measurement range, which is beneficial for the sensing device to determine whether it is affected by the interference device within this interference measurement range, and is further beneficial for improving the accuracy of interference measurement in the sensing scenario.

[0026] In a possible implementation, the second candidate interference measurement resource is related to the measurement dimension of the sensing measurement.

[0027] In this embodiment, the second candidate interference measurement resource provided by the interference device to the sensing device not only considers the capabilities of the interference device, but also takes into account the measurement dimension of the sensing measurement, which is beneficial for providing the sensing device with a more accurate candidate interference measurement resource 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 being beneficial for improving the efficiency of interference measurement.

[0028] In a possible implementation, the measurement dimension of the sensing measurement includes any one of the following:

[0029] 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 combined with angle measurement.

[0030] In a possible implementation, the interference measurement method further includes: 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; wherein, the parameters of the sensing signal include at least one of signal power, signal phase or signal amplitude; the sensing measurement resources include at least one of time domain resources, frequency domain resources or port resources.

[0031] In this implementation, the sensing device can determine the interference level of the interfering device on the sensing device based on the interference measurement information. The sensing device determines the sensing signal sent during the subsequent sensing measurement with reference to the interference measurement information, which is beneficial to reducing the interference of the interfering device in the measurement dimension of the sensing measurement, thereby effectively mitigating or eliminating the sensing interference.

[0032] In a possible implementation, the interference measurement method further includes: if the interference degree indicated by the interference measurement information is greater than a first threshold, the sensing device sends a first message to the interfering device, and the first message includes an interference measurement report, and the interference measurement report includes the measurement dimension of the sensing measurement, the interference measurement information and a second threshold.

[0033] Optionally, the first threshold is the maximum interference that the sensing device can tolerate. For example, when the interference degree received by the sensing device is greater than the first threshold, the sensing measurement service of the sensing device may not be able to proceed normally.

[0034] Optionally, the second threshold is used to indicate the desired interference degree of the sensing device. It can be understood that the second threshold is used to indicate to what extent the sensing device expects to control the interference during normal operation. It can also be understood that the second threshold is used to indicate to what extent the sensing device recommends the interfering device to reduce the interference. Optionally, the second threshold is less than or equal to the first threshold.

[0035] In this implementation, in order to reduce the interference caused by the interfering device to the sensing device, in addition to providing the interference measurement information and the measurement dimension to the interfering device, the sensing device also provides a reference value (i.e., the second threshold) for recommending to the interfering device to what extent to reduce the interference measurement signal, which is beneficial to the quick and effective interference adjustment of the interfering device and improves the efficiency and accuracy of interference management.

[0036] In a possible implementation, the interference measurement method further includes: if the interference degree indicated by the interference measurement information is greater than a first threshold, the sensing device sends a first message to the interfering device, and the first message includes at least one adjustment instruction, and each adjustment instruction is used to instruct the interfering device to adjust a parameter of the interference measurement signal.

[0037] In this embodiment, the sensing device directly provides an adjustment instruction for adjusting the interference measurement signal to the interference device, and the interference device only needs to adjust the parameters of the interference measurement signal according to this adjustment instruction. This is beneficial to saving the processing overhead of the interference device for calculating the adjusted parameters.

[0038] In a possible implementation manner, 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; the resources include at least one of time-domain resources, frequency-domain resources or port resources.

[0039] In this embodiment, the sensing device can send the first information to the interference device, and this first information provides a basis for the interference device to adjust the interference measurement signal, which is beneficial for the interference device to accurately adjust the interference measurement signal to reduce the interference of the interference device on the sensing device in the measurement dimension of the sensing measurement, so as to effectively mitigate or eliminate the sensing interference.

[0040] In a second aspect, the present application provides an interference measurement method. This interference measurement method can be executed by the interference device or by components of the interference device (such as components such as a processor, a chip or a chip system, etc.). Taking the interference device as an example, the interference device acquires a first interference measurement resource, and the first interference measurement resource is related to the measurement dimension of the sensing measurement of the sensing device; then, the interference device sends an interference measurement signal through the first interference measurement resource.

[0041] In the present application, since the first interference measurement resource for transmitting the interference measurement signal between the sensing device and the interference device is related to the measurement dimension of the sensing measurement of the sensing device, therefore, this interference measurement signal can reflect the interference situation of the interference device on the sensing device in the measurement dimension of the sensing measurement, which is beneficial for the sensing device to more accurately detect the influence of the interference device on the sensing device and improve the efficiency of interference measurement in the sensing scenario.

Specifically, the interference device receives a first interference measurement request, which includes the measurement dimension of the sensing measurement and first resource indication information for indicating at least one first candidate interference measurement resource, and each first candidate interference measurement resource is related to the measurement dimension of the sensing measurement; then, the interference device sends a first interference measurement response, which includes second resource indication information for indicating the first interference measurement resource. Wherein, the first interference measurement resource is determined based on at least one first candidate interference measurement resource.

Wherein, the first interference measurement resource is determined based on at least one second candidate interference measurement resource.

[0050] Optionally, the second candidate interference measurement resource is related to the measurement dimension of the sensing measurement.

[0073] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0074] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned accompanying drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments described here can be implemented in an order other than that illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0075] It should be understood that the term "and / or" in this text is merely a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Here, A and B can be single or multiple. Additionally, the character " / " in this text generally indicates that the associated objects before and after are in an "or" relationship. Furthermore, the expression "at least one of the following" or its similar expressions in this text are used to represent any combination of the listed items. For example, at least one of A, B, and (or) C can represent the following situations: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, B and C exist simultaneously, A and C exist simultaneously, and A, B, and C exist simultaneously. Here, A, B, and C can be single or multiple.

[0076] The interference measurement method provided in this application is mainly applied to interference measurement in a sensing scenario. For example, before or during the sensing measurement of a target object by a sensing device, the sensing device measures the interference situation of an interfering device on the sensing device. The sensing scenario mainly involves a sensing device, an interfering device, and a target object. Among them, the sensing device can be an access network device, a terminal device, or other devices or apparatuses capable of implementing sensing measurement functions through wireless signals; the interfering device can be an access network device, a terminal device, or other devices capable of emitting wireless signals that may cause interference to other communication devices; the target object can be an unmanned aerial vehicle, a vehicle, a building, a roadside device, etc.

[0077] Exemplarily, Figure 1 is an example diagram of a sensing scenario. As Figure 1 shown, the sensing device can be access network device 1. Access network device 1 performs sensing measurement on target objects such as roadside devices and vehicles, and the interfering device that may cause interference to access network device 1 is access network device 2. Another example is that the sensing device can be terminal device 1. Terminal device 1 performs sensing measurement on target objects such as roadside devices and vehicles, and the interfering device that may cause interference to terminal device 1 can be access network device 2 or terminal device 2.

[0078] Exemplarily, the aforementioned sensing device and / or interfering device can be terminal devices and / or access network devices in a 5G NR (5G New Radio) system, the 6th generation mobile communication technology (6G) system, and subsequent evolved formats. The communication between the sensing device and the interfering device can be cellular network communication or proximity communication (PC5), which is not limited in this application. For example, Figure 1The cellular network communication is adopted between the terminal device 1 as the sensing device and the access network device 2 as the interfering device. For another example, Figure 1 The PC5 communication is adopted between the terminal device 1 as the sensing device and the terminal device 2 as the interfering device in

[0079] Among them, the terminal device includes a device that provides voice and / or data connectivity to users. For example, it may include a handheld device with wireless connection capabilities or a processing device connected to a wireless modem. In cellular network communication, the terminal device can communicate with the radio access network (RAN) through the Uu interface and communicate with the core network (e.g., the 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 can 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 can be a mobile phone, tablet (Pad), computer with wireless transceiver function, virtual reality (VR) device, augmented reality (AR) device, 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 so on.

[0080] In addition, the access network device can be any device with wireless transceiver functions and can be used to be responsible for functions related to the air interface. For example, functions such as wireless link maintenance, radio resource management, and partial mobility management functions. In addition, the access network device can also be configured with a baseband unit (BBU) and has baseband signal processing functions. Exemplarily, the access network device can be the access network device (radio access network, RAN) that currently provides services to the terminal device. Currently, some common examples of the access network device are: Node B (NB), evolved Node B (eNB or eNodeB), next-generation Node B (gNB) in the 5G new radio (NR) system, nodes in the 6G system (for example, xNodeB), transmission reception point (TRP), radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved Node B or home Node B (HNB)), etc. In addition, in network architectures such as cloud radio access network (CloudRAN) or open radio access network (ORAN), the access network device can 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 device including the CU and the DU splits the protocol layer of the gNB in the NR system, and the functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0081] It should be understood that in practical applications, the sensing device and the interference device can be implemented using any of the foregoing examples. In this embodiment and subsequent embodiments, only the sensing device and the interference device are used as examples for introduction.

[0082] Since the interference in the sensing scenario is mainly due to the overlap of sensing signals of different users in one or more measurement dimensions, which causes different sensing signals to affect each other and ultimately reduces the sensing performance. Therefore, to measure the interference in the sensing scenario, it is necessary to define and measure the interference in dimensions other than the time domain, frequency domain, and spatial domain in combination with the sensing requirements. For this purpose, the present application provides an interference measurement method and related devices for measuring the interference level to sensing in the sensing scenario and improving the accuracy and efficiency of interference measurement in the sensing scenario.

[0083] The following will introduce the main process of the interference measurement method provided by the present application in combination with Figure 2 This interference measurement method can be executed by the sensing device and the interfering device, or by components of the sensing device and the interfering device (such as components such as a processor, a chip, or a chip system). In the following, an example of execution by the sensing device and the interfering device will be used for introduction. As Figure 2 shown, the interference measurement method includes the following steps:

[0084] Step 201, the sensing device acquires the first interference measurement resource; correspondingly, the interfering device acquires the first interference measurement resource.

[0085] Among them, the first interference measurement resource is a resource for measuring interference in the sensing scenario. It can be understood that this first interference measurement resource is used to transmit interference measurement signals in the sensing scenario. For example, before or during the sensing measurement, in order to avoid interference affecting the sensing measurement, the sensing device and the interfering device will acquire the first interference measurement resource, and then the interfering device can send interference measurement signals through the first interference measurement resource, and the sensing device can receive interference measurement signals through the first interference measurement resource.

[0086] Among them, the first interference measurement resource is related to the measurement dimension of the sensing measurement of the sensing device. It can be understood that the time domain characteristics, frequency domain characteristics, or spatial domain characteristics of this first interference measurement resource match the measurement dimension of the sensing measurement. It can also be understood that the interference measurement signals transmitted on this first interference measurement resource have a high probability of interfering with the sensing measurement of the sensing device in this measurement dimension.

[0087] Optionally, the measurement dimension of the sensing 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 combined with angle measurement.

[0088] 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 will give a simple example for introduction:

[0089] In one example, if the measurement dimension is distance measurement, the frequency-domain bandwidth of the first interference measurement resource needs to satisfy a constraint. For example, the frequency-domain bandwidth of the first interference measurement resource is greater than a 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 with a relatively large 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 there is interference for the sensing device, that is, to improve the accuracy of interference measurement in the scenario of sensing distance.

[0090] In another example, if the measurement dimension is speed measurement, the time-domain characteristics of the first interference measurement resource need to satisfy a constraint. For example, the duration of the first interference measurement resource in the time domain is greater than a second threshold and / or the time-domain repetition period is less than a third threshold. It can be understood that when the sensing device measures whether there is interference in the speed dimension, configuring the first interference measurement resource with a relatively long duration and a relatively small time-domain repetition interval is beneficial for the sensing device to obtain a higher speed resolution and a larger speed measurement range during interference measurement, and to improve the accuracy of interference measurement in the scenario of sensing speed.

[0091] In another example, if the measurement dimension is angle measurement, the spatial-domain characteristics of the first interference measurement resource need to satisfy a constraint. The spatial-domain characteristics include the characteristics of the antenna ports. For example, the number of antenna ports involved in the first interference measurement resource is greater than a 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 a higher angle resolution during interference measurement, and to improve the accuracy of interference measurement in the scenario of sensing angle.

[0092] 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 satisfy a constraint. The spatial-domain characteristics include the characteristics of the antenna ports. For example, the frequency-domain bandwidth of the first interference measurement resource is greater than a fifth threshold, and / or the number of antenna ports involved in the first interference measurement resource is greater than a 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 relatively large bandwidth and involving a relatively large number of antenna ports is beneficial for the sensing device to obtain higher distance and angle resolutions during interference measurement, so as to obtain a higher imaging resolution, and to improve the accuracy of interference measurement in the scenario of sensing imaging. In another example, if the measurement dimension is distance and speed joint measurement, that is, the sensing measurement measures both distance and speed, the first interference measurement resource needs to satisfy both the constraints for distance measurement and the constraints for speed measurement. For example, both the frequency-domain bandwidth and the time-domain characteristics of the first interference measurement resource need to satisfy the constraints. For details, please refer to the examples where the measurement dimension is distance and the examples where the measurement dimension is speed.

[0093] In another example, if the measurement dimension is distance combined with angle measurement, that is, the sensing measurement measures both distance and angle, then the first interference measurement resource needs to satisfy the constraints on both distance measurement and angle measurement. For example, both the frequency domain bandwidth and the spatial domain characteristics of the first interference measurement resource need to satisfy the constraints. For details, please refer to the example where the measurement dimension is distance and the example where the measurement dimension is angle.

[0094] In another example, if the measurement dimension is speed combined with angle measurement, that is, the sensing measurement measures both speed and angle, then the first interference measurement resource needs to satisfy the constraints on both speed measurement and angle measurement. For example, both the time domain characteristics and the spatial domain characteristics of the first interference measurement resource need to satisfy the constraints. For details, please refer to the example where the measurement dimension is speed and the example where the measurement dimension is angle.

[0095] In another example, if the measurement dimension is distance, speed combined with angle measurement, that is, the sensing measurement measures distance, speed, and angle simultaneously, then the first interference measurement resource needs to satisfy the constraints on distance measurement, speed measurement, and angle measurement simultaneously. For example, both the frequency domain bandwidth, the time domain characteristics, and the spatial domain characteristics of the first interference measurement resource need to satisfy the constraints. For details, please refer to the example where the measurement dimension is distance, the example where the measurement dimension is speed, and the example where the measurement dimension is angle.

[0096] It should be understood that in practical applications, for a certain measurement dimension, the first interference measurement resource may also have other constraints in the time domain, frequency domain, or spatial domain, and examples are not listed one by one in this application.

[0097] 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 sensing measurement in the measurement dimension. It can be understood that this first interference measurement resource is not only related to the measurement dimension of the sensing measurement but also related to the effective measurement range of the sensing measurement in the measurement dimension.

[0098] Optionally, the interference measurement range is used to indicate the range where the sensing measurement cannot tolerate interference. It can be understood that when the projection of the interference measurement signal in this measurement dimension after sensing processing falls within this interference measurement range, this interference measurement signal will interfere with the sensing measurement; when the projection of the interference measurement signal in this measurement dimension after sensing processing does not fall within this interference measurement range, this interference measurement signal will not interfere with the sensing measurement.

[0099] 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 this distance dimension. For example, when 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, if the interference measurement range is 0m to 1000m and the interval length of the interference measurement range is 1000m, 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 this speed dimension. For example, when 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, if the interference measurement range is -30m / s to +30m / s and the interval length of the interference measurement range is 2×30m / s, 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 are also affected by the interference measurement range in this measurement dimension, and examples are not listed one by one here.

[0100] It should be noted that the first interference measurement resource can be a reused interference measurement resource (IMR) in traditional technologies or a newly defined resource for interference measurement for the sensing scenario, and this application does not limit it. Exemplarily, if the first interference measurement resource is a reused IMR in traditional technologies, 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, the CSI-RS resource includes a non-zero power (NZP) CSI-RS resource and a zero power (ZP) CSI-RS resource.

[0101] In addition, the sensing device and the interference device can respectively obtain the first interference measurement resource, or can negotiate and determine the first interference measurement resource after signaling exchange. The following are introduced separately:

[0102] In a possible implementation, the sensing device and the interfering device respectively obtain the first interference measurement resource. For example, the sensing device receives pre-configured first configuration information or first configuration information from other communication devices, and 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 other communication devices, and the second configuration information is used to configure the first interference measurement resource.

[0103] 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 the interference measurement resource negotiated and determined by the sensing device and the interfering device after signaling interaction.

[0104] In one implementation, the sensing device triggers the negotiation to determine the 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 foregoing at least one candidate interference measurement resource. For specific details, please refer to the relevant introduction in the subsequent text Figure 4 Corresponding to the relevant introduction in the embodiment, it will not be elaborated here.

[0105] In another implementation, the interfering device triggers the 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 foregoing at least one second candidate interference measurement resource. For specific details, please refer to the relevant introduction in the subsequent text Figure 5 Corresponding to the relevant introduction in the embodiment, it will not be elaborated here.

[0106] Step 202, 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.

[0107] Among them, the interference measurement signal generally refers to the signal sent by the interfering device through the first interference measurement resource. The interference measurement signal can be a signal newly defined by the interfering device, or the working signal of the interfering device, or a signal pre-configured 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 signals may be different.

[0108] In a possible implementation, if the sensing device and the interfering device respectively obtain the 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 pre-configured trigger period or trigger event.

[0109] In another possible implementation, if the sensing device and the interfering device negotiate and determine the first interference measurement resource through signaling interaction, 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 transmission of an interference measurement signal through the first interference measurement resource. For specific details, please refer to the relevant introduction in the following text. Figure 4 Or Figure 5 For the relevant introduction in the corresponding embodiments, it will not be elaborated here.

[0110] Step 203: The sensing device determines interference measurement information based on the interference measurement signal.

[0111] In this embodiment, step 203 is an optional step. It should be understood that the sensing device can calculate the interference measurement information every time it receives an interference measurement signal. In addition, the sensing device can also trigger the determination of the interference measurement information based on at least one interference measurement signal when the number of consecutive received interference measurement signals reaches a threshold or when the duration of waiting to receive the interference measurement signal reaches a threshold. This application does not limit.

[0112] Specifically, the sensing device performs sensing processing on the interference measurement signal for the measurement dimension of the sensing measurement and outputs the interference measurement information. Among them, the interference measurement information is used to indicate the interference situation of the interference measurement signal on the sensing device in the sensing measurement dimension.

[0113] It should be understood that different measurement dimensions associated with the first interference measurement resource result in differences in the interference measurement signals received by the sensing device, and further result in different interference measurement information determined by the sensing device.

[0114] Exemplarily, if the measurement dimension of the sensing measurement is distance measurement, the sensing device performs pulse compression processing on the received interference measurement signal in the fast time dimension (i.e., the distance dimension) to obtain the interference measurement information in the distance dimension. Exemplarily, if the measurement dimension of the sensing measurement is speed measurement, the sensing device performs matched filtering processing on the received interference measurement signal in the slow time dimension (i.e., the speed dimension) to obtain the interference measurement information in the speed dimension or the Doppler dimension. Exemplarily, if the measurement dimension of the sensing measurement is angle measurement, the sensing device performs processing such as matched filtering or super-resolution estimation in the array angle dimension on the received interference measurement signal to obtain the interference measurement information in the angle dimension. Exemplarily, if the measurement dimension of the sensing measurement is imaging measurement, the sensing device performs imaging processing (for example, back projection (BP) algorithm processing or wavenumber domain algorithm processing, etc.) on the received interference measurement signal to obtain the interference measurement information in the imaging space dimension.

[0115] Optionally, the interference measurement information includes the 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:

[0116] 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 a preset power.

[0117] Optionally, the interference measurement information includes the interference measurement values within the interference measurement range of the interference measurement signal in 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, 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 can perform quantization processing on the interference measurement result (e.g., the pulse compression result in the distance dimension) based on predefined quantization rules, and the output interference measurement information includes the index after quantization of the amplitude value of the pulse compression result.

[0118] Exemplarily, Figure 3A and Figure 3B are examples where the measurement dimension of the perception measurement is the angle measurement. Figure 3A and Figure 3B In, the abscissa is the angle of the angle spectrum corresponding to the transmitting antenna array, and the ordinate is the angle of the angle spectrum corresponding to the receiving antenna array. Figure 3A The position A in is the angle spectrum obtained after the interference signal is subjected to perception processing, Figure 3A The position B in is the angle spectrum obtained after the target signal is subjected to perception processing, and the white frame line range is the interference measurement range in the two-dimensional angle domain. As Figure 3A shown, both the target signal and the interference signal have a large amplitude response in the two-dimensional angle domain after perception processing. Since the target signal and the interference signal do not overlap in the two-dimensional angle domain after perception processing, that is, the angle spectrum at position B and the angle spectrum at position A do not overlap, and even the angle spectrum at position A is not within the interference measurement range, therefore, the interference signal does not form an effective interference to the target signal. For the situation shown in Figure 3A there is no need to perform interference suppression. As Figure 3BAs shown, as the target signal changes, the position of the target signal in the two-dimensional angular domain after sensing processing moves to position C, and the interference measurement range also changes as position C moves. The position of the interference signal in the two-dimensional angular domain after sensing processing (i.e., position A) is within the interference measurement range. The target signal and the interference signal are close to overlapping in the two-dimensional angular domain after sensing processing, that is, position C and position A are close to overlapping. At this time, the interference signal forms an effective interference to the target signal, and interference suppression is required.

[0119] Optionally, the sensing device can determine at least one reference point within the interference measurement range. The sensing device determines the interference measurement value at the position where the reference point is located based on the interference measurement signal. At this time, the interference measurement information output by the sensing device includes the interference measurement value at the position where the reference point is located.

[0120] Exemplarily, still taking Figure 3A and Figure 3B as an example, the range of the white frame line is the interference measurement range in the two-dimensional angular domain, and the white dots are reference points. When the sensing device calculates the interference measurement value, it can only calculate the interference measurement value of one or more reference points shown in Figure 3A or Figure 3B , rather than necessarily calculating for the entire interference measurement range, which is beneficial to saving the computing overhead of the sensing device.

[0121] In this embodiment, since the first interference measurement resource for transmitting the interference measurement signal between the sensing device and the interference device is related to the measurement dimension of the sensing measurement of the sensing device, the interference measurement signal can reflect the interference situation of the interference device on the sensing device in the measurement dimension of the sensing measurement, which is beneficial for the sensing device to more accurately detect the influence of the interference device on the sensing device and improve the accuracy of interference measurement in the sensing scenario. In addition, the first interference measurement resource is also related to the interference measurement range, and the interference measurement range is the effective measurement range of the sensing measurement in the measurement dimension. It is beneficial for the sensing device to determine whether it is affected by the interference device within the interference measurement range, which is beneficial to further improving the accuracy of interference measurement in the sensing scenario.

[0122] Next, an embodiment of the interference measurement method provided by the present application will be introduced in conjunction with Figure 4 . In this embodiment, the interference measurement is initiated by the sensing device, that is, the sensing device triggers the negotiation with the interference device to determine the first interference measurement resource. As shown in Figure 4 , the sensing device and the interference device mainly perform the following steps:

[0123] Step 401, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement.

[0124] Among them, the first candidate interference measurement resource is a candidate resource for determining the first interference measurement resource. Each of the at least one first candidate interference measurement resources is related to the measurement dimension of the sensing measurement. For the explanations of the measurement dimension of the sensing measurement and the first interference measurement resource, please refer to the relevant introduction in step 201 above, which will not be elaborated here.

[0125] In a possible implementation manner, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement and the characteristics of the interference measurement resource corresponding to the measurement dimension.

[0126] Exemplarily, taking the measurement dimension as speed measurement as an example, it is required that the time-domain characteristics of the interference measurement resource for measuring interference in the speed dimension satisfy the constraints. For example, the constraint is that the duration of the interference measurement resource in the time domain is greater than a second threshold and / or the time-domain repetition period is less than a third threshold. The sensing device determines at least one time-frequency resource that satisfies the foregoing constraints as the first candidate interference measurement resource. Among them, the foregoing constraints may be pre-configured in the sensing device or determined by the sensing device based on an algorithm, which is not limited in this application.

[0127] In another possible implementation manner, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement and the first correspondence. Among them, 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 pre-configured, which is not limited in this application.

[0128] Exemplarily, the first correspondence may be shown in Table 1-1 as follows:

[0129] Table 1-1

[0130] Measurement Dimensions of Perceptual Measurement Interference Measurement Resources Distance Measurement Resource 1, Resource 2 Speed Measurement Resource 3, Resource 4, Resource 5 Angle Measurement Resource 6, Resource 7 Imaging Measurement Resource 8

[0131] As shown in the example of Table 1-1, if the sensing measurement dimension is distance measurement, the sensing device can determine Resource 1 and / or Resource 2 as the first candidate interference measurement resource based on the sensing measurement dimension and the first correspondence; if the sensing measurement dimension is speed measurement, the sensing device can determine at least one of Resource 3, Resource 4, or Resource 5 as the first candidate interference measurement resource based on the sensing measurement dimension and the first correspondence. The remaining examples are similar and will not be elaborated here.

[0132] 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 the explanation of the interference measurement range, please refer to the relevant introduction in step 201 above, which will not be elaborated here. The following will be introduced separately:

[0133] In a possible implementation, the sensing device determines at least one first candidate interference measurement resource based on the measurement dimension of the sensing measurement and the interference measurement range. Wherein, the measurement dimension of the sensing measurement is used to determine the constraint on the characteristics of the interference measurement resource corresponding to the measurement dimension, and the interference measurement range is used to determine the threshold of the constraint.

[0134] Exemplarily, if the measurement dimension of the sensing 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 -v m / s to +v m / 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 sensing measurement is speed measurement and the interference measurement range is -v m / s to +v m / s, the sensing device selects at least one time-frequency resource as at least one first candidate interference measurement resource from the time-frequency resources with a time-domain repetition period less than λ / (2v).

[0135] 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. Wherein, 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 can be specified by a protocol or pre-configured, which is not limited in this application.

[0136] Exemplarily, taking the measurement dimension of the sensing measurement as speed measurement as an example, the second correspondence can be shown in Table 2-1 as follows:

[0137] Table 2-1

[0138]

[0139] Exemplarily, taking Table 1-1 and Table 2-1 as examples, if the measurement dimension of the perception measurement is speed measurement, the perception device determines, based on this measurement dimension and the first corresponding relationship 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 this interference measurement range and the second corresponding relationship shown in Table 2-1, that the interference measurement resource applicable to 5 m / s to 10 m / s is Resource 4, that is, the perception device determines that Resource 4 is the first candidate interference measurement resource. It should be understood that Table 2-1 only shows the second corresponding relationship when the measurement dimension is speed measurement. In actual applications, there are also second corresponding relationships for other measurement dimensions, which are not listed one by one in this application.

[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 refer to the second corresponding relationship to determine the first candidate interference measurement resource. For example, the measurement dimension of the perception measurement is speed measurement, and the interference measurement range is 4 m / s to 8 m / s. The perception device refers to the interference measurement range in the second corresponding relationship that is closest to 4 m / s to 8 m / s to determine the interference measurement resource, that is, refers to 5 m / s to 10 m / s to determine that Resource 4 is the first candidate interference measurement resource.

[0141] In another possible implementation, the perception device determines at least one first candidate interference measurement resource based on the measurement dimension of the perception measurement, the perception service type, the first corresponding relationship, and the third corresponding relationship. Among them, the first corresponding relationship includes at least one measurement dimension and at least one interference measurement resource corresponding to each measurement dimension. The third corresponding relationship includes at least one perception service type corresponding to the same measurement dimension and at least one interference measurement resource corresponding to each perception service type. This third corresponding relationship can be stipulated by the protocol or pre-configured, and this application does not limit it.

[0142] Exemplarily, taking the measurement dimension of the perception measurement being speed measurement as an example, the third corresponding relationship can be shown in Table 3-1 as follows:

[0143] Table 3-1

[0144]

[0145] 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, based on this measurement dimension and the first corresponding relationship shown in Table 1-1, that the interference measurement resources applicable to speed measurement include Resource 3, Resource 4, and Resource 5. If the perception service type is to measure the speed of non-motor vehicles, the perception device determines, based on this perception service type and the third corresponding relationship shown in Table 3-1, that the interference measurement resource applicable to measuring the speed of non-motor vehicles is Resource 3, 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 corresponding relationship when the measurement dimension is speed measurement, and there are also third corresponding relationships for other measurement dimensions in actual applications, which are not listed one by one in this application.

[0146] It should be noted that step 401 is an optional step. For example, at least one first candidate interference measurement resource is pre-configured in the perception device. Whenever the perception device needs to perform a measurement, the perception device may not execute step 401 and directly trigger the execution of step 402.

[0147] Step 402, the perception device sends a first interference measurement request; correspondingly, the interference device receives the first interference measurement request.

[0148] In one example, if communication is possible between the perception device and the interference device, the perception device sends a first interference measurement request to the interference device; correspondingly, the interference device receives the first interference measurement request from the perception device. For example, both the perception device and the interference device are access network devices (e.g., TRP), and the first interference measurement request is transmitted between the perception device and the interference device through the Xn interface. Another example is that both the perception device and the interference device are terminal devices, and the first interference measurement request is transmitted between the perception device and the interference device through the PC5 interface. Another example is that the perception device is a terminal device and the interference device is an access network device; or the perception device is an access network device and the interference device is a terminal device, then the first interference measurement request is transmitted between the perception device and the interference device through the Uu interface.

[0149] 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 a coordinating device; correspondingly, the interfering device receives the first interference measurement request from the sensing device via the coordinating device. For example, both the sensing device and the interfering device are terminal devices and do not support PC5 communication, and the coordinating device is an access network device. The terminal device acting as the sensing device and the terminal device acting as the interfering device forward the first interference measurement request through the access network device. Another example is that both the sensing device and the interfering device are access network devices, and there is no available communication interface between the sensing device and the interfering device. The coordinating device is another access network device, which communicates with the sensing device and the interfering device respectively through the Xn interface. Thus, the access network device acting as the sensing device and the access network device acting as the interfering device forward the first interference measurement request through the access network device acting as the coordinating device.

[0150] It should be understood that the sensing device may send the first interference measurement request to one interfering device or 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.

[0151] Among them, the first interference measurement request includes the measurement dimension of the sensing measurement and the 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 receiving the first interference measurement request, the interfering device can know that the first candidate interference measurement resource is related to the measurement dimension based on the measurement dimension.

[0152] Exemplarily, if the first interference measurement request includes information indicating distance measurement and information indicating Resource 1 and Resource 2, the interfering device knows from 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.

[0153] Optionally, the first resource indication information may be the index of each first candidate interference measurement resource among at least one first candidate interference measurement resource. For example, if the sensing device and the interfering device have pre-agreed on the indexes of some resources through pre-configuration or signaling negotiation before performing step 402, the sensing device may indicate to the interfering device which resources are the first candidate interference measurement resources through the indexes of the resources.

[0154] Optionally, the first interference measurement request further includes an interference measurement range, so that the interfering device takes the interference measurement range into consideration in the subsequent process of determining the first interference measurement resource.

[0155] Step 403: The interference device determines a first interference measurement resource based on the measurement dimension of the perception measurement and at least one first candidate interference measurement resource.

[0156] In a possible implementation manner, the interference device selects, from at least one first candidate interference measurement resource, the resource supported by the interference device as the first interference measurement resource, that is, the first interference measurement resource is a subset of at least one first candidate interference measurement resource. Exemplarily, if the perception device provides 3 first candidate interference measurement resources, which are 1 MHz 40 ms, 10 MHz 10 ms, and 20 MHz 5 ms respectively, and if the interference device only supports transmitting signals on a 10 MHz resource, then the interference device determines 10 MHz 10 ms as the first interference measurement resource.

[0157] Optionally, the interference device may also determine, from at least one first candidate interference measurement resource with reference to the measurement dimension, the resource supported by the interference device and suitable for interference measurement in this measurement dimension as the first interference measurement resource. Exemplarily, if the perception device provides 4 first candidate interference measurement resources for interference measurement in the distance measurement dimension, which are 1 MHz 40 ms, 10 MHz 10 ms, 10 MHz 40 ms, and 20 MHz 5 ms respectively. If the interference device only supports transmitting signals on a 10 MHz resource, and 10 MHz 10 ms is more suitable for interference measurement in the distance measurement dimension than 10 MHz 40 ms, then the interference device determines 10 MHz 10 ms as the first interference measurement resource.

[0158] 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. Exemplarily, if the perception device provides 5 first candidate interference measurement resources for interference measurement in the distance measurement dimension, which are 1 MHz 40 ms, 10 MHz 10 ms, 10 MHz 15 ms, 10 MHz 40 ms, and 20 MHz 5 ms respectively. If the interference device only supports transmitting signals on a 10 MHz resource, and both 10 MHz 10 ms and 10 MHz 15 ms are relatively suitable for interference measurement in the distance measurement dimension, then the interference device selects, from 10 MHz 10 ms and 10 MHz 15 ms, the resource that is more likely to cause interference to the interference measurement range in the distance measurement dimension as the first interference measurement resource.

[0159] It should be noted that the first interference measurement resource determined by the interference device may not belong to at least one first candidate interference measurement resource provided by the sensing device. For example, the sensing device may not be aware of the capabilities of the interference device, resulting in no resources in the at least one first candidate interference measurement resource provided by the sensing device that the interference device can use, or no resources applicable to this measurement dimension and supported by the interference device. In this case, the interference device determines the first interference measurement resource based on the measurement dimension of the sensing measurement and the resources supported by the interference device. At this time, the first interference measurement resource determined by the interference device may partially overlap or completely non-overlap with a certain first candidate interference measurement resource provided by the sensing device in the time domain, frequency domain, or spatial domain, which is not limited in this application.

[0160] In a possible implementation, if the interference device fails to determine a suitable resource as the first interference measurement resource from at least one first candidate interference measurement resource, the interference device determines the first interference measurement resource based on the measurement dimension of the sensing measurement and the constraints of the characteristics of the interference measurement resource corresponding to this measurement dimension.

[0161] Exemplarily, taking the measurement dimension as speed measurement as an example, it is required that the time-domain characteristics of the interference measurement resource used for measuring interference in the speed dimension satisfy the constraints. For example, the constraint is that the duration of the interference measurement resource in the time domain is greater than a second threshold and / or the time-domain repetition period is less than a third threshold. The interference device determines at least one time-frequency resource that satisfies the foregoing constraints and is supported by the interference device as the first interference measurement resource. Among them, the foregoing constraints may be pre-configured in the interference device or determined by the interference device based on an algorithm, which is not limited in this application.

[0162] In another possible implementation, if the interference device fails to 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 interference device also determines the first interference measurement resource based on the measurement dimension of the sensing measurement and the interference measurement range. Among them, the measurement dimension of the sensing measurement is used to determine the constraints of the characteristics of the interference measurement resource corresponding to this measurement dimension, and the interference measurement range is used to determine the threshold of this constraint.

[0163] Exemplarily, if the measurement dimension of the sensing measurement is speed measurement, the time-domain characteristics of the interference measurement resources 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 resources 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 -v m / s to +v m / s (v is a non-zero real number), then the time-domain repetition period of the interference measurement resources 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 sensing measurement is speed measurement and the interference measurement range is -v m / s to +v m / s, the interference device selects at least one time-frequency resource supported by the interference device as the first interference measurement resource from the time-frequency resources with a time-domain repetition period less than λ / (2v).

[0164] In this step, the interference device preferentially screens the first interference measurement resources from at least one first candidate interference measurement resource provided by the sensing device. Since at least one first candidate interference measurement resource provided by the sensing device is related to the measurement dimension of the sensing measurement, the interference device only needs to screen the resources supported by the interference device from at least one first candidate interference measurement resource as the first interference measurement resources, which is beneficial to reducing the complexity of the interference device to determine the first interference measurement resources and saving the processing overhead of the interference device. In addition, when the interference device fails to determine the first interference measurement resources from at least one first candidate interference measurement resource, the interference device can determine the first interference measurement resources based on the measurement dimension (and the interference measurement range) of the sensing measurement, which is beneficial to ensuring the reliability of the interference device to determine the first interference resources.

[0165] It should be noted that step 403 is an optional step. For example, if the interference device does not participate in the interference measurement, the interference device does not execute step 403; if the interference device participates in the interference measurement, the interference device executes step 403.

[0166] Step 404, the interference device sends a first interference measurement response; correspondingly, the sensing device receives the first interference measurement response.

[0167] Among them, the first interference measurement response is used to indicate whether the interference device participates in interference measurement. For example, the first interference measurement response includes first indication information. One value of the first indication information indicates that the interference device participates in interference measurement, and another value of the first indication information indicates that the interference device does not participate in measurement. It should be understood that if the first interference measurement response indicates that the interference device does not participate in interference measurement, the interference device and the sensing device do not perform the subsequent steps 405 to 406; if the first interference measurement response indicates that the interference device participates in interference measurement, the interference device and the sensing device perform the 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.

[0168] Step 405, the interference device sends an interference measurement signal through the first interference measurement resource; correspondingly, the sensing device receives the interference measurement signal sent by the interference device through the first interference measurement resource.

[0169] Step 406, the sensing device determines interference measurement information based on the interference measurement signal.

[0170] In this embodiment, steps 405 to 406 are similar to the previous steps 202 to 203. For specific details, please refer to the relevant descriptions in the previous steps 202 to 203, which will not be elaborated here.

[0171] In this embodiment, since the sensing device provides the measurement dimension of the sensing measurement and at least one first candidate interference measurement resource to the interference device, the interference device determines the first interference measurement resource based on the measurement dimension of the sensing measurement and at least one first candidate interference measurement resource. Since the finally determined first interference measurement resource for transmitting the interference measurement signal is related to the measurement dimension of the sensing measurement of the sensing device, the interference measurement signal can reflect the interference situation of the interference device on the sensing device in the measurement dimension of the sensing measurement, which is beneficial to the sensing device to more accurately detect the influence of the interference device on the sensing device and improve the accuracy of interference measurement in the sensing scenario. In addition, the sensing device triggers the negotiation with the interference device to determine the first interference measurement resource, which is beneficial for the sensing device to initiate interference measurement when interference management is required, so as to realize the interference measurement performed by the sensing device on demand and improve the flexibility of interference measurement.

[0172] Next, in combination with Figure 5 Another embodiment of the interference measurement method provided by this application will be introduced. In this embodiment, the interference device initiates interference measurement, that is, the interference device triggers the negotiation with the sensing device to determine the first interference measurement resource. As Figure 5 shown, the sensing device and the interference device mainly perform the following steps:

[0173] Step 501, the interference device sends a second interference measurement request; correspondingly, the sensing device receives the second interference measurement request.

[0174] In one example, if communication is possible between the interference device and the sensing device, the interference device sends a second interference measurement request to the sensing device; correspondingly, the sensing device receives the second interference measurement request from the interference device. For example, both the interference device and the sensing device are access network devices (e.g., TRP), and the second interference measurement request is transmitted between the interference device and the sensing device through the Xn interface. Another example is that both the interference device and the sensing device are terminal devices, and the second interference measurement request is transmitted between the interference device and the sensing device through the PC5 interface. Yet another example is that the interference device is a terminal device and the sensing device is an access network device; or the interference device is an access network device and the sensing device is a terminal device, then the second interference measurement request is transmitted between the interference device and the sensing device through the Uu interface.

[0175] In another example, if direct communication is not possible between the interference device and the sensing device, the interference device can forward the second interference measurement request to the sensing device through a coordination device; correspondingly, the sensing device receives the second interference measurement request from the interference device via the coordination device. For example, both the interference device and the sensing device are terminal devices and do not support PC5 communication, and the coordination device is an access network device. The terminal device acting as the interference device and the terminal device acting as the sensing device forward the second interference measurement request through the access network device. Another example is that both the interference device and the sensing device are access network devices, and there is no available communication interface between the interference device and the sensing device. The coordination device is another access network device, which communicates with the sensing device and the interference device through the Xn interface respectively. Thus, the access network device acting as the interference device and the access network device acting as the sensing device forward the second interference measurement request through the access network device acting as the coordination device.

[0176] In addition, the interference device can send the second interference measurement request to one sensing device or multiple sensing devices, which is not limited in this application. When the interference device sends the second interference measurement resource to multiple sensing devices, the interference device can broadcast the second interference measurement resource. For example, the interference device periodically broadcasts the second interference measurement request to request the surrounding sensing devices to cooperate in the interference measurement, so that the surrounding sensing devices can update the interference situation. The interference device notifies the sensing devices to perform interference measurement in a broadcast mode, which is beneficial to improving the efficiency of interference measurement.

[0177] Among them, 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 interference device. The second candidate interference measurement resource is a resource supported by the interference device, that is, the interference device can send a working signal or a signal dedicated to interference measurement on the second candidate interference measurement resource.

[0178] Optionally, the second candidate interference measurement resource is related to the measurement dimension of the sensing measurement. The second interference measurement request includes the third resource indication information and the measurement dimension related to the second candidate interference measurement resource.

[0179] In a possible implementation manner, at least one second candidate interference measurement resource is related to the same measurement dimension. For example, each second candidate interference measurement resource among at least one second candidate interference measurement resource is related to distance measurement. Another example is that each second candidate interference measurement resource among at least one second candidate interference measurement resource is related to speed measurement. Another example is that each second candidate interference measurement resource among at least one second candidate interference measurement resource is related to angle measurement. Another example is that each second candidate interference measurement resource among at least one second candidate interference measurement resource is related to imaging measurement.

[0180] Optionally, the interference device can send the second interference measurement request multiple times. The second candidate interference measurement resources included in the second interference measurement request sent at the same time are related to one measurement dimension, and the second candidate interference measurement resources included in the second interference measurement requests sent at different times are related to different measurement dimensions. For example, the interference device broadcasts the second interference measurement request at regular intervals. The second candidate interference measurement resources included in the second interference measurement request broadcast by the interference device at the first moment are related to distance measurement, the second candidate interference measurement resources included in the second interference measurement request broadcast by the interference device at the second moment are related to speed measurement, and the second candidate interference measurement resources included in the second interference measurement request broadcast by the interference device at the third moment are related to angle measurement, etc.

[0181] In this embodiment, the second candidate interference measurement resources provided by the interference device to the sensing device not only consider the capabilities of the interference device, but also consider the measurement dimensions of the sensing measurement, which is beneficial to providing the sensing device with more accurate candidate interference measurement resources applicable to a certain measurement dimension, and is also beneficial to the sensing device to more quickly determine the first interference measurement resource applicable to a certain measurement dimension, thereby being beneficial to improving the efficiency of interference measurement. In addition, for the second candidate interference measurement resources of different measurement dimensions, the interference device sends them in different second interference measurement requests respectively, which can provide different second candidate interference measurement resources for the sensing device to select for different measurement dimensions, and is beneficial to the sensing device to measure the interference of different measurement dimensions and improve the diversity of interference measurement.

[0182] In another possible implementation, different second candidate interference measurement resources among at least one second candidate interference measurement resource are related to different measurement dimensions. For example, the third resource indication information included in the second interference measurement request indicates 3 second candidate interference measurement resources. One second candidate interference measurement resource is related to distance measurement, another second candidate interference measurement resource is related to speed measurement, and another second candidate interference measurement resource is related to angle measurement. In this example, the second interference measurement request includes 3 second candidate interference measurement resources and the measurement dimensions related to each second candidate interference measurement resource.

[0183] In this implementation, the interference device can provide multiple second candidate interference measurement resources to the sensing device through one second interference measurement request, and the multiple candidate interference measurement resources are respectively applicable to multiple measurement dimensions. This is beneficial for the sensing device to obtain second candidate interference measurement resources for different measurement dimensions through fewer signaling, so as to facilitate the sensing device to initiate interference measurement for other measurement dimensions subsequently, which is beneficial for 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 distance measurement and a candidate interference measurement resource 2 related to speed measurement, then 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 for saving signaling overhead.

[0184] Step 502, the sensing device determines a first interference measurement resource based on the measurement dimension of the sensing measurement and at least one second candidate interference measurement resource.

[0185] Among them, the measurement dimension of the sensing measurement is the measurement dimension of the sensing measurement that the sensing device is performing, or the measurement dimension of the sensing measurement that the sensing device is about to initiate.

[0186] Specifically, the sensing device selects a resource applicable to perform interference measurement in this measurement dimension from at least one second candidate interference measurement resource and determines it as the first interference measurement resource. This first interference measurement resource is a subset of at least one second candidate interference measurement resource.

[0187] In a 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 constraints of the characteristics of the interference measurement resource corresponding to this measurement dimension.

[0188] Exemplarily, taking the measurement dimension as speed measurement as an example, it is required that the time-domain characteristics of the interference measurement resources used for measuring interference in the speed dimension satisfy the constraints. For example, the constraint is that the duration of the interference measurement resources 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 the resources that satisfy the foregoing constraints from at least one second candidate interference measurement resource as the first interference measurement resource. Among them, the foregoing constraints may be pre-configured in the sensing device or determined by the sensing device based on an algorithm, which is not limited in this application.

[0189] 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 the explanation of the first correspondence, please refer to the relevant introduction in step 401 above, which will not be elaborated here.

[0190] Exemplarily, taking Table 1-1 introduced above as an example, if the sensing measurement dimension is distance measurement, the sensing device can determine the resources corresponding to this measurement dimension as Resource 1 and Resource 2 based on the sensing measurement dimension and the first correspondence. If Resource 1 belongs to the second candidate interference measurement resource, for example, Resource 1 overlaps or partially overlaps with a certain second candidate interference measurement resource, then the sensing device determines Resource 1 as the first interference measurement resource.

[0191] Optionally, when determining 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 is an introduction to each:

[0192] In a 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 interference measurement range.

[0193] Among them, the measurement dimension of the sensing measurement is used to determine the characteristic constraints of the interference measurement resources corresponding to this measurement dimension, and the interference measurement range is used to determine the threshold of this characteristic constraint. The sensing device determines the resources that satisfy the characteristic constraints of the interference measurement resources corresponding to this measurement dimension and reach the threshold of this constraint from at least one second candidate interference measurement resource as the first interference measurement resource.

[0194] Exemplarily, if the measurement dimension of the sensing measurement is speed measurement, the time-domain characteristics of the interference measurement resources 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 -v m / s to +v m / s (v is a non-zero real number), then the time-domain repetition period of the interference measurement resources 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 sensing measurement is speed measurement and the interference measurement range is -v m / s to +v m / s, the sensing device selects, from at least one second candidate interference measurement resource, the time-frequency resource with a time-domain repetition period less than λ / (2v) as the first interference measurement resource.

[0195] In another possible implementation manner, 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 the explanations of the first correspondence and the second correspondence, please refer to the relevant introductions in step 401 above, which will not be elaborated here.

[0196] Exemplarily, taking Table 1-1 and Table 2-1 introduced above as an example, if the sensing measurement dimension is speed measurement, the sensing device determines, based on the sensing 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 sensing device determines, based on this 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 sensing device determines, from at least one second candidate interference measurement resource, the second candidate interference measurement resource that overlaps or partially overlaps with Resource 4 as the first interference measurement resource.

[0197] In another possible implementation manner, 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 the explanations of the first correspondence and the third correspondence, please refer to the relevant introductions in step 401 above, which will not be elaborated here.

[0198] Exemplarily, taking Table 1-1 and Table 3-1 introduced above as examples, if the measurement dimension of the perception measurement is speed measurement, the perception device determines that the interference measurement resources applicable to speed measurement include Resource 3, Resource 4, and Resource 5 based on this measurement dimension and the first corresponding relationship shown in Table 1-1. If the perception service type is to measure the speed of non-motor vehicles, the perception device determines that the interference measurement resource applicable to measuring the speed of non-motor vehicles is Resource 3 based on this perception service type and the third corresponding relationship shown in Table 3-1. Then, the perception device determines the second candidate interference measurement resource that overlaps or partially overlaps with Resource 3 from at least one second candidate interference measurement resource as the first interference measurement resource.

[0199] It should be understood that if the perception device fails to select the first interference measurement resource from at least one second candidate interference measurement resource, the perception device does not participate in the interference measurement.

[0200] It should be noted that step 502 is an optional step. For example, if the perception device does not participate in the interference measurement, the perception device does not execute step 502; if the perception device participates in the interference measurement, the perception device executes step 502.

[0201] Step 503, the perception device sends a second interference measurement response; correspondingly, the interference device receives the second interference measurement response.

[0202] Among them, 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] 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 interference device and the perception device do not execute the subsequent steps 504 to step 505; if the second interference measurement response indicates that the perception device participates in the interference measurement, the interference device and the perception device execute the subsequent steps 504 to step 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.

[0204] Step 504, the interference device sends an interference measurement signal through the first interference measurement resource; correspondingly, the perception device receives the interference measurement signal sent by the interference device through the first interference measurement resource.

[0205] Step 505, the perception device determines interference measurement information based on the interference measurement signal.

[0206] In this embodiment, steps 504 to 505 are similar to steps 202 to 203 described above. For specific details, please refer to the relevant descriptions in steps 202 to 203 above, which will not be elaborated here.

[0207] In this embodiment, since the interference 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 the measurement dimension of the sensing measurement and the at least one second candidate interference measurement resource. Since the finally determined first interference measurement resource for transmitting the interference measurement signal is related to the measurement dimension of the sensing measurement of the sensing device, the interference measurement signal can reflect the interference situation of the interference device on the sensing device in the measurement dimension of the sensing measurement, which is beneficial for the sensing device to more accurately detect the influence of the interference device on the sensing device and improve the efficiency of interference measurement in the sensing scenario. In addition, the interference device triggers the negotiation with the sensing device to determine the first interference measurement resource, which can achieve the active triggering of interference management by the interference device in the scenario with fewer interference devices and improve the efficiency of interference management.

[0208] 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 Figure 6 shown, the sensing device and the interference device can also perform the following steps:

[0209] Step 601, 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.

[0210] Among them, the sensing signal is the measurement signal sent by the sensing device when performing the sensing measurement. The sensing measurement resources are used to send the aforementioned sensing signal. Exemplarily, the sensing 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), etc., or a redefined continuous wave (CW) signal, a frequency modulated CW (FMCW) signal, a linear frequency modulation (LFM) signal, a phase modulated CW (PMCW) signal, an orthogonal frequency division multiplexing (OFDM) signal, etc.

[0211] Since the sensing device can determine the interference level of the interfering device on the sensing device based on the interference measurement information, to reduce the impact of the interfering device on the sensing device, the sensing device determines the sensing signal to be sent during the subsequent sensing measurement process with reference to the interference measurement information. 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. Among them, the parameters of the sensing signal include at least one of signal power, signal phase, or signal amplitude; the sensing measurement resources include at least one of time-domain resources, frequency-domain resources, or port resources.

[0212] In a possible implementation, the sensing device determines the parameters of the sensing signal based on the interference measurement information, and configures specific parameters to minimize the interference received by the sensing signal in the measurement dimension.

[0213] In an example, the difference between the power of the sensing signal determined by the sensing device and the signal power of the interference measurement signal is greater than a preset threshold. For example, if the sensing 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, then the sensing device determines that the power of the sensing signal to be sent is -30 dBm + 80 dBm, that is, 50 dBm.

[0214] In another example, the waveform of the sensing signal determined by the sensing device is orthogonal to the waveform of the interference measurement signal, so that the sensing signal and the interference measurement signal do not interfere with each other in the measurement dimension. For example, when both the sensing device and the interfering device use the FMCW waveform, and at the same time, when the frequency f1 of the FMCW waveform of the sensing device is close to the frequency f2 of the FMCW waveform of the interfering device, the interfering device may interfere with the sensing device. To avoid interference, the sensing 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 interfering device satisfies the preset threshold at any time. Another example is that when both the sensing device and the interfering device use the PMCW waveform, to avoid interference, the sensing device can adjust the phase sequence used to generate the PMCW waveform, so that the cross-correlation between the PMCW waveform of the sensing device and the PMCW waveform of the interfering device is reduced below the threshold.

[0215] 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.

[0216] In one example, the sensing measurement resources occupied by the sensing signal determined by the sensing device do not overlap with the first interference measurement resources. Since the sensing measurement resources do not overlap with the first interference measurement resources, the sensing device is not interfered by the interfering device.

[0217] In another example, the sensing measurement resources occupied by the sensing signal determined by the sensing device overlap or partially overlap with the first interference measurement resources, so that the sensing measurement in the measurement dimension is not affected by the signal sent by the first interference measurement resources.

[0218] Optionally, after the sensing device executes step 601, the sensing device may further execute step 603, and then the interfering device may also execute step 603. If, after the sensing device executes step 601, the interference of the sensing device by the interfering device is reduced to almost not affecting the sensing measurement, the sensing device may not execute step 602, and thus may not trigger the interfering device to execute step 603.

[0219] Step 602, the sensing device sends the first information; correspondingly, the interfering device receives the first information.

[0220] Optionally, if the interference degree indicated by the interference measurement information is greater than the first threshold, the sensing device sends the first information to the interfering device. Wherein, the first threshold is the critical value for triggering 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 degree received by the sensing device is greater than the first threshold, the sensing measurement service of the sensing device may not be able to proceed normally.

[0221] It should be understood that the first threshold may be the threshold of peak interference or the threshold of average interference, and the present application does not limit. For example, if the interference measurement information is the average power of the interference measurement signal in the measurement dimension after sensing processing, the first threshold is the threshold of the average power (i.e., the threshold of average interference). Another example is that if the peak power of the interference measurement signal in the measurement dimension after sensing processing, the first threshold is the threshold of the peak power (i.e., the threshold of peak interference). Another example is that if the ratio of the power of the interference measurement signal after sensing processing to the preset power, the first threshold is the threshold of the ratio.

[0222] Optionally, the first threshold is related to the measurement dimension of the sensing measurement.

[0223] Optionally, 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; the resources include at least one of time domain resources, frequency domain resources or port resources.

[0224] In addition, the first information can be implemented in various ways, which will be introduced separately below:

[0225] In one possible implementation, the first information includes an interference measurement report, which includes the measurement dimension of the sensing measurement, interference measurement information, and a second threshold. The second threshold is the degree of interference that the sensing device expects to achieve. It can be understood that the second threshold is used to indicate to what extent the interference should be controlled during the normal operation of the sensing device. It can also be understood that the second threshold is used to indicate to what extent the sensing device recommends that the interfering device lower the interference. Optionally, the second threshold is less than or equal to the first threshold.

[0226] In this implementation, in order to reduce the interference caused by the interfering device to the sensing device, in addition to providing the interference measurement information and the measurement dimension to the interfering device, the sensing device also provides a reference value (i.e., the second threshold) for recommending to what extent the interfering device should lower the interference measurement signal, which is beneficial to the rapid and effective interference adjustment of the interfering device and improves the efficiency and accuracy of interference management.

[0227] In another possible implementation, the first information includes at least one adjustment instruction, and each adjustment instruction is used to instruct the interfering device to adjust a parameter of the interference measurement signal. Among them, the parameter includes at least one of signal power, signal phase, or signal amplitude.

[0228] In this implementation, the sensing device directly provides the adjustment instruction for adjusting the interference measurement signal to the interfering device, and the interfering device only needs to adjust the parameter of the interference measurement signal according to this adjustment instruction. This is beneficial to saving the processing overhead of the interfering device for calculating the adjusted parameter.

[0229] Optionally, the adjustment instruction can be an instruction indicating the adjustment amplitude of the interference measurement parameter. Exemplarily, taking the adjustment of power as an example, the adjustment instruction included in the first information is 10 dB, indicating that the interfering device should lower the power of the interference measurement signal by 10 dB.

[0230] Step 603, the interfering device adjusts the parameter of the interference measurement signal and / or the resource occupied by the interference measurement signal based on the first information.

[0231] In one embodiment, the first information includes an interference measurement report, which includes the measurement dimension of the sensing measurement, interference measurement information, and a second threshold. The interference measurement information can reflect the current degree of interference of the sensing device, and the second threshold indicates the desired degree of interference of the sensing device. The interference device adjusts the signal power of the interference measurement signal based on the second threshold, so that the degree of interference of the adjusted interference measurement signal on the sensing device is less than or equal to the second threshold. For example, before adjustment, the power of the interference measurement signal is 40 dBm, the average power of the interference measurement signal after sensing processing in the measurement dimension is -60 dBm, and the second threshold is -80 dBm. Then the interference device determines that the power of the adjusted interference measurement signal is 40 dBm - (-60 dBm + 80 dBm), that is, 20 dBm, and the average power of the adjusted interference measurement signal after sensing processing in the measurement dimension is -80 dBm.

[0232] In another embodiment, the first information includes at least one adjustment instruction, and each adjustment instruction is used to instruct the interference device to adjust a parameter of the interference measurement signal. The interference device adjusts the interference measurement signal based on the at least one adjustment instruction. For example, taking the adjustment of power as an example, the adjustment instruction included in the first information is 10 dB, and the interference device reduces the power of the interference measurement signal by 10 dB.

[0233] In this embodiment, after the sensing device determines the interference measurement information, the sensing device can determine the sensing signal based on the interference measurement information, or instruct the interference device to adjust the interference measurement signal through the first information. Therefore, the interference of the interference device in the measurement dimension of the sensing measurement can be reduced by adjusting the sensing signal or the interference measurement signal, so as to more effectively slow down or eliminate the sensing interference.

[0234] Corresponding to the solution given in the foregoing method embodiment, the embodiment of the present application also provides a corresponding device (for example, a communication device) and a communication system. The device includes modules or units corresponding to each part in the foregoing embodiment. The module or unit can be software, hardware, or a combination of software and hardware.
