[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0031] In this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0032] It should be noted that in this disclosure, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0033] In the field of wireless communication, deterministic analysis of signal coverage is a critical step in ensuring network performance and quality of service. This analysis relies heavily on a deep understanding of the surrounding environment, including factors such as the shape, location, and material of objects within it. However, current techniques, such as 3D environment reconstruction based on optical photography or laser point clouds, while accurately capturing the shape and location information of each object in the environment, have significant limitations in obtaining material information about objects.

[0034] The materials of objects in the environment have a significant impact on the propagation of wireless communication signals. Different materials exhibit varying characteristics in signal reflection, absorption, and transmission, directly affecting signal transmission distance, intensity, and stability. Therefore, without determining the materials of objects in the environment, deterministic analysis of signal coverage will struggle to achieve the desired accuracy. Thus, a method for determining the materials of objects in the environment is urgently needed.

[0035] Ray tracing is a deterministic modeling method for channels, treating signal propagation as the refraction, reflection, and scattering of rays. For example, Figure 1 This paper presents a ray tracing effect diagram in a three-dimensional environment. In forward ray tracing, multiple rays are emitted from the transmitting end, and the rays are tracked according to the principle of electromagnetic wave propagation to obtain the path of the rays to the receiving end, and further obtain the characteristics of the received signal.

[0036] Nvidia has developed a simulation tool for wireless communication using TensorFlow, which implements a differentiable ray tracing process. By comparing the measured results with the simulation results, we can differentiate the difference with respect to the parameters involved in ray tracing, and adjust the uncertain parameters based on the derivative, including the dielectric constant of the environmental material and antenna parameters.

[0037] In view of this, this disclosure provides a method for determining the material of an object by acquiring a signal measurement report in the target environment and determining the material of the object in the target environment based on the signal measurement report. This method enables the determination of the material of objects in the environment, which is beneficial for accurately analyzing the signal coverage in the environment.

[0038] The object material determination method provided in this disclosure can be applied to systems with various communication standards. For example, the systems to which this object material determination method is applicable include, but are not limited to, Long Term Evolution (LTE) systems, various versions based on LTE evolution, 5th-generation mobile communication technology (5G) systems, and ambient internet of things (Ambient IoT) systems. Furthermore, the object material determination method provided in this disclosure can also be applied to future-oriented communication systems (such as 6G communication systems).

[0039] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G, and future mobile communication networks) in this disclosure embodiment may include at least a first communication node and a second communication node. It should be understood that, in this example, in the downlink, the first communication node may be a network-side device (e.g., including but not limited to a base station), and the second communication node may be a terminal-side device (e.g., including but not limited to a terminal). Of course, in the uplink, the first communication node may also be a terminal-side device, and the second communication node may also be a network-side device. In device-to-device communication between the two communication nodes, both the first and second communication nodes can be a base station or a terminal. The first and second communication nodes may be referred to as the first node and the second node, respectively.

[0040] For example, taking the first node as the base station and the second node as the terminal, such as... Figure 2 The diagram shown is a structural schematic of a communication system provided in an embodiment of this disclosure. The communication system includes a terminal 10 and a base station 20. There may be one or more terminals 10 and base stations 20, and the number is not limited.

[0041] In some embodiments, base station 20 provides wireless access service to terminal 10. A base station 20 provides at least one service coverage area (also referred to as a cell). Terminal 10 entering this area can communicate with base station 20 via wireless signals to receive the wireless access service provided by base station 20.

[0042] In some embodiments, a base station (BS) can be a base station in LTE, Long Term Evolution Advanced (LTEA) or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system. The base station can include various network-side devices such as macro base stations, micro base stations, home base stations, wireless remote extensions, reconfigurable intelligent surfaces (RISs), routers, relays, transmit-and-receive points (TRPs), wireless fidelity (WIFI) devices, and user equipment (UE).

[0044] It should be noted that, Figure 2 This is just an example framework diagram. Figure 2 The number of devices included and the names of each device are unlimited, except for... Figure 2 In addition to the devices shown, the communication system may also include other devices, such as core network equipment.

[0045] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0046] This disclosure provides a method for determining the material of an object, applying a first node. For example... Figure 3 As shown, the method includes the following steps:

[0047] S101. Obtain a signal measurement report from the target environment.

[0048] The signal measurement report includes at least one of the following: reference signal received power (RSRP), channel matrix, multipath information received by the first node, multipath information received by the second node, channel state information, identification information of the second node, location information of the second node, and attitude information of the antenna on the second node side. The signal measurement report may also be referred to as the signal measurement result, and this disclosure does not impose any limitation on this terminology.

[0049] The received multipath information includes at least one of the following: the time delay of each received path, the power of each received path, and the angle of each received path.

[0050] In some embodiments, the location information of the second node is the location information of the second node when it receives the measurement signal sent by the first node.

[0051] In some embodiments, obtaining a signal measurement report in the target environment includes: receiving and measuring the measurement signal sent by the second node in the target environment to obtain a signal measurement report in the target environment; or, receiving a signal measurement report in the target environment sent by the second node.

[0052] In some embodiments, receiving and measuring the measurement signal sent by the second node in the target environment to obtain a signal measurement report in the target environment includes: sending measurement configuration information to the second node, the measurement configuration information including at least one of the following: frequency domain information of the measurement signal (including the frequency point of the measurement signal), power of the measurement signal, time domain information of the measurement signal, and type of the measurement signal; receiving and measuring the measurement signal sent by the second node in the target environment based on the measurement configuration information to obtain a signal measurement report in the target environment.

[0053] The power of the measurement signal includes the transmission power and the reception power of the measurement signal.

[0054] The time-domain information of the measurement signal includes the time slot information occupied by the measurement signal. For example, the transmission time slot and the reception time slot of the measurement signal.

[0055] The type of measurement signal can be at least one of the following: sounding signal, demodulation reference signal (DMRS) signal, ZC sequence (Zadoff-Chu sequence), or M sequence (pseudo-random sequence).

[0056] Antenna attitude information includes at least one of the following: antenna angle (e.g., antenna azimuth, antenna elevation, etc.), antenna height, and antenna position. Adjustment of antenna attitude may include adjustments to at least one of the following: antenna angle (e.g., antenna azimuth, antenna elevation, etc.), antenna height, and antenna position.

[0057] In some embodiments, the measurement signal is sent after the second node moves to the first target position, and / or after the antenna attitude on the second node side is adjusted to the first antenna attitude.

[0058] In some embodiments, the measurement configuration information may also include information on the first target location that the second node needs to move to and / or information on the first antenna attitude that the second node side antenna attitude needs to be adjusted to.

[0059] Understandably, the first node can use gradient and target environment information to determine whether the position of the second node needs adjustment. If adjustment is required, the information on the first target position that the second node needs to move to can be determined and configured in the measurement configuration information to instruct the second node to move its position, thereby obtaining better material recognition results.

[0060] In some embodiments, before receiving and measuring the measurement signal transmitted by the second node in the target environment based on the measurement configuration information, the method further includes: the first node moving to the second target location; and / or, the first node adjusting the attitude information of the first node-side antenna to the attitude of the second antenna.

[0061] In some embodiments, the second node receives state information of the second node sent by the second node, the state information of the second node including the position information of the second node when sending measurement signals and / or the attitude information of the antenna.

[0062] In some embodiments, receiving a signal measurement report in the target environment sent by the second node includes: sending a measurement signal to the second node in the target environment; and receiving the signal measurement report in the target environment sent by the second node, wherein the signal measurement report is obtained by the second node receiving and measuring the measurement signal.

[0063] In some embodiments, before sending the measurement signal to the second node in the target environment, the method further includes: sending measurement configuration information to the second node, the measurement configuration information including at least one of the following: frequency domain information of the measurement signal, power of the measurement signal, time domain information of the measurement signal, and type of the measurement signal. This allows the second node to receive the measurement signal sent by the first node in the target environment based on the measurement configuration information, thereby improving signal reception efficiency.

[0064] In some embodiments, the measurement signal is sent after the first node moves to the second target position, and / or after the antenna attitude on the first node side is adjusted to the second antenna attitude.

[0065] In some embodiments, a first indication message is received from a second node, the first indication message being used to instruct the first node to send a measurement signal to the second node in the target environment.

[0066] In some embodiments, the first indication information is sent after the second node moves to the first target location, and / or after the antenna attitude on the second node side is adjusted to the first antenna attitude. The first indication information includes the state information of the second node, which includes information about the first target location and / or information about the first antenna attitude.

[0067] In some embodiments, the measurement configuration information may also include information on the first target location that the second node needs to move to and / or information on the first antenna attitude that the second node side antenna attitude needs to be adjusted to.

[0068] In some embodiments, the information of the first target location is configured based on signaling (e.g., radio resource control (RRC) signaling).

[0069] In some embodiments, the information of the second target location is configured based on signaling (e.g., RRC signaling).

[0070] In some embodiments, the information of the first antenna attitude is configured based on signaling (e.g., RRC signaling).

[0071] In some embodiments, the second antenna attitude information is configured based on signaling (e.g., RRC signaling).

[0072] It is understandable that, when both the first and second nodes are movable terminal devices, the first target position can be determined by the second node itself in conjunction with its surrounding environment, and vice versa. The first or second target position can also be determined by the first node based on gradient and target environment information. In this way, moving the first and second nodes to appropriate positions before measuring the signal can improve measurement accuracy and further enhance the accuracy of determining the object's material composition.

[0073] In some embodiments, sending measurement configuration information to the second node includes: sending second indication information to the second node, the second indication information being used to indicate the start of measuring measurement signals in the target environment to obtain a signal measurement report; receiving state information of the second node sent by the second node in response to the second indication information, the state information of the second node including the position information of the second node and / or the attitude information of the second node's side antenna; and sending measurement configuration information to the second node based on the state information of the second node.

[0074] In some embodiments, measurement configuration information is sent to the second node based on the status information of the second node and the information of the target environment.

[0075] S102. Based on the signal measurement report, determine the material of objects in the target environment.

[0076] In some embodiments, a signal measurement report is input into an object material determination model to obtain the material of an object in the target environment. The object material determination model is used to determine the material of an object in the target environment based on the signal measurement report. The object material determination model is trained on a preset model using training samples, which consist of the signal measurement report. The training process includes updating the initial discrete probability distribution of the object material in the environment on different sample materials based on gradients. The training process also includes taking the derivative of the difference between the signal measurement report and the channel estimate generated based on the current discrete probability distribution with respect to the discrete probability distribution, and generating the required gradient.

[0077] In this way, based on the comparison between signal measurement reports and ray tracing theoretical results, gradients are used for iterative training to identify the material of objects in the target environment.

[0078] For example, assuming a defined 3D environment with given wireless parameters for both the UE and BS, the channel between them is determined by the materials of various objects in the environment. The channel coefficients can be approximated by ray tracing, and the ray tracing result can be expressed as:

[0079] h = f(materials),

[0080] Here, f(materials) is differentiable with respect to materials. h can represent a parameter in the channel measurement report, such as the channel coefficient h (channel matrix h). The channel coefficient h will be used as an example below.

[0081] If the material of each object in the environment is unknown, this patent treats the material of each object as a discrete probability distribution. For example, assuming the possible materials of each object with an unknown material in the environment are {wooden board, marble}, then the material of each object with an unknown material can be represented as a discrete probability distribution vector (p1, p2). Initially, it can be assumed that the probability of obtaining each material is the same, i.e., the discrete probability distribution vector is (0.5, 0.5). Since materials are a discrete probability distribution, they are not differentiable and cannot be updated using gradients. This disclosure uses differentiable transformation techniques (such as Gumbel-softmax) to transform the final channel coefficient h obtained by taking values ​​according to the probability distribution into a differentiable behavior, thereby enabling gradient-based updates to the probability distribution.

[0082] Suppose the discrete probability distribution of a material is (p1, p2, ... p... k We calculate (y1, y2, ... y) as shown in the following formula. k ),

[0083]

[0084] Among them, g i =-log(-log(u) i )),u i ~U(0,1) is a scalar obtained by sampling from the Gumbel distribution, and τ is a scalar parameter chosen by the user, similar to the temperature parameter in softmax. This yields (y1,y2,…y k After that, it is used as the one-hot representation of the material, and thus the value corresponding to (p1, p2, ... p) is calculated. k The channel coefficient h of ) and this process relative to (p1,p2,…p k Differentiable, p i Let k be the probability of the i-th possible material, where k is a positive integer.

[0085] Meanwhile, it is assumed that the measured results of the channel coefficients under this environment are as follows: (That is, the channel coefficients determined based on the signal measurement report obtained from the above channel measurements), then The loss is the actual measured result. The difference between the channel estimate (estimated channel coefficients h) and the channel estimate generated based on the current discrete probability distribution. Channel measurements are performed at multiple points, using gradient descent and leveraging... Can be used for pi To update, that is:

[0086]

[0087] Where r is the learning rate chosen by the user. After multiple iterations and convergence (after multiple iterations satisfy the iteration conditions), the final discrete probability distribution corresponding to each possible object material in the environment is obtained, and thus the material distribution of objects in the environment is obtained.

[0088] It can be observed whether there are objects that have a major influence on the channel coefficient, which greatly affects the material identification results. Specifically, if the channel received by a receiver is mainly affected by object A, then the material of object A can be determined quickly and accurately using this channel data. Conversely, if the channel coefficient is relatively evenly affected by multiple objects, then the channel coefficient is less effective for material identification, and it may only become effective after most objects have been identified. This property is mainly affected by the positions of the transmitter and receiver. In actual measurements, we need to configure the measurement signal according to the positions of both. If conditions permit, the positions of the transmitter and receiver can be adjusted, for example, by placing the UE closer to one object while moving it away from other objects, to improve the identification effect.

[0089] Based on this, signal measurement reports are obtained from the target environment; based on these reports, the material of objects in the target environment is determined. This enables the determination of the material of objects in the environment, which is beneficial for accurately analyzing the signal coverage in the environment.

[0090] This disclosure provides a method for determining the material of an object, using a second node. For example... Figure 4 As shown, the method includes the following steps:

[0095] In some embodiments, the measurement signal is sent after the second node moves to the first target position, and / or the antenna attitude on the second node side is adjusted to the first antenna attitude.

[0096] In some embodiments, the measurement configuration information may also include information on the first target location that the second node needs to move to and / or information on the first antenna attitude that the second node side antenna attitude needs to be adjusted to.

[0097] In some embodiments, the status information of the second node is sent to the first node.

This allows the second node to receive the measurement signal transmitted by the first node in the target environment based on the measurement configuration information, thereby improving signal reception efficiency.

[0100] In some embodiments, the measurement signal is sent after the first node moves to the second target position, and / or after the antenna attitude on the first node side is adjusted to the second antenna attitude.

[0101] In some embodiments, a first indication message is sent to a first node, the first indication message being used to instruct the first node to send a measurement signal to a second node in a target environment.

[0102] In some embodiments, the first indication information is sent after the second node moves to the first target position, and / or after the antenna attitude on the second node side is adjusted to the first antenna attitude. The first indication information includes the state information of the second node, which includes information about the first target position and / or information about the first antenna attitude.

[0103] In some embodiments, the measurement configuration information may also include information on the first target location that the second node needs to move to and / or information on the first antenna attitude that the second node side antenna attitude needs to be adjusted to.

[0107] For a more detailed description of step S201, as well as a more detailed description of each technical feature therein, and a description of the beneficial effects, please refer to the corresponding first node side method embodiment section above, which will not be repeated here.

[0108] Based on this, this disclosure treats the material of each 3D model in the environment as a discrete variable, and uses derivatives to update the probability distribution on the discrete variable, thereby identifying the material of each object in the 3D environment. Based on experiments and theoretical derivations, the positions of the transmitter (first node) and receiver (second node), as well as the errors between the measurement results of the previous stage and the theoretical analysis, all affect the material identification effect and can be used to guide the next measurement action. Based on the need for material identification of objects in the environment, this disclosure designs the signal measurement process to achieve better identification results.
