Description

Communication method and apparatus

[0001] The present application claims priority from the Chinese patent application No. 202410745191.8 filed on June 7, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a communication method and apparatus. BACKGROUND

[0003] The 3rd Generation Partnership Project (3GPP) is actively promoting the research of Communication and Sensing Integration, in which sensing technology is a core component. Various different sensing use cases have been identified, and the channel modeling of sensing is being further explored.

[0004] In the positioning scenario, sensing technology shows its unique advantages, especially the ability to combine with multipath effects for positioning. The multipath effect in wireless communication refers to the phenomenon that wireless signals pass through multiple paths to reach the receiving end during transmission. By analyzing these multipath signals, sensing technology can extract information closely related to positioning, such as signal arrival time and arrival angle, thereby achieving more accurate positioning of the target. In addition, sensing technology is not only suitable for positioning static targets, but also widely used in tracking and positioning dynamic targets. By continuously sensing the position and motion state of the target, the system can update the target's position information in real time, achieving continuous and accurate tracking of the target.

[0005] However, sensing technology pays more attention to the multipath information reflected by specific sensing objects and / or sensing areas, which means that the traditional measurement and reporting method cannot be directly applied to sensing technology. SUMMARY

[0006] The present application provides a communication method and apparatus, which can realize sensing of sensing objects and / or sensing areas.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0008] In a first aspect, a communication method is provided. The execution subject of the method can be a signal receiving device, a component or device (e.g., a processor, a chip, or a chip system) applied to the signal receiving device, or a logic module or software capable of realizing all or part of the function of the signal receiving device. The communication method comprises: obtaining first information for determining a first path from a path indication device, the first path being at least one path related to a sensing object and / or a sensing area, and sending second information for indicating a measurement result corresponding to the first path to a sensing device.

[0009] In the first aspect, the above-mentioned first information and second information are exchanged between the above-mentioned devices, so that the signal receiving device can provide the measurement result corresponding to the path related to the sensing object and / or the sensing area to the sensing device, reduce redundant reporting, and ensure that the measurement result required by the sensing device can be reported without being screened out, thereby achieving the sensing purpose.

[0010] In combination with the first aspect, in a possible design, the second information comprises a measurement result of the first path; or the second information comprises the measurement result of the first path and matching degree information, where the matching degree information is used to indicate a matching degree of the first path and the first information.

[0011] In this design, when the second information comprises the measurement result of the first path, the signaling overhead required by the second information is small. When the second information comprises the measurement result of the first path and the matching degree information, the matching degree of the first path and the first information can be determined based on the second information.

[0012] In combination with the first aspect, in a possible design, the first information is obtained by receiving the first information from a sensing network element.

[0013] In this design, the path indication device is the sensing network element, and the first information is provided by the sensing network element to the signal receiving device, so that the first information can be used to determine the second information.

[0014] In combination with the first aspect, in a possible design, the first information indicates a first angle interval; or the first information indicates a second angle interval. Optionally, when the first information indicates the first angle interval, the first path comprises a path with an angle of arrival in the first angle interval; or when the first information indicates the second angle interval, the first path comprises a path with a difference in angle of arrival compared to a preset first angle in the second angle interval.

[0015] In this design, the first information is designed to indicate an expected angle, such as the first angle interval or the second angle interval, and the first path can be determined based on the expected angle.

[0016] With reference to the first aspect, in a possible design, the first information indicates a first time interval; or the first information indicates a second time interval. Optionally, when the first information indicates the first time interval, the first path includes a path with a time of arrival in the first time interval; or when the first information indicates the second time interval, the first path includes a path with a difference in time of arrival compared with a preset first time in the second time interval.

[0017] In this design, the first information is designed to indicate an expected time, for example, the first time interval or the second time interval, and the first path can be determined based on the expected time.

[0018] With reference to the first aspect, in a possible design, the method further includes: transmitting a signal and receiving a return wave of the signal, the signal being used for sensing a sensing object and / or a sensing area; or receiving a signal, the signal being used for sensing a sensing object and / or a sensing area.

[0019] In this design, the signal receiving device is applicable to a self-transmitting and self-receiving scenario, and transmits the signal and receives the return wave of the signal. Alternatively, the signal receiving device is applicable to a scenario in which different devices play the roles of a signal transmitter and a signal receiver, and receives the signal.

[0020] With reference to the first aspect, in a possible design, the transmitting the signal and receiving the return wave of the signal includes: transmitting the signal and receiving the return wave of the signal based on a first angle interval, where the first information includes the first angle interval; or transmitting the signal and receiving the return wave of the signal based on a second angle interval, where the first information includes the second angle interval.

[0021] In this design, the signal receiving device transmits the signal and receives the return wave of the signal, i.e., a self-transmitting and self-receiving scenario, and the first information indicates the first angle interval or the second angle interval. In this case, the signal receiving device transmits the signal based on the first angle interval or the second angle interval to emit the signal and receive the return wave of the signal, so that the signal can pass through the sensing object and / or the sensing area that needs to be sensed.

[0023] In the design, the second information is further used to indicate whether the path from the sensing object and / or the sensing area to the signal receiving device is a visual path or a non-visual path, which is a more accurate indication of whether the path from the sensing object and / or the sensing area to the signal receiving device is a visual path or a non-visual path compared to the conventional indication of whether the complete path from the signal sending device to the signal receiving device is a visual path or a non-visual path, and the sensing accuracy can be improved.

[0024] In combination with the first aspect, in a possible design, the first information is further used to indicate at least one sensing object and / or sensing area; and the second information is used to indicate the measurement result corresponding to the first path corresponding to the at least one sensing object and / or sensing area.

[0025] In the design, when there are multiple sensing objects and / or sensing areas, the first information further indicates the sensing objects and / or sensing areas, which can be used to distinguish the sensing objects and / or sensing areas, so that the signal receiving device can determine the second information corresponding to the sensing objects and / or sensing areas based on the first information, and then send the second information to the sensing device, so that the sensing device can determine the second information corresponding to the sensing objects and / or sensing areas, and thus accurate sensing can be implemented.

[0027] In the design, after receiving the third information, the signal receiving device can determine the measurement model used when performing signal measurement based on the third information, for example, when the third information indicates that the path is a visual path, a stronger signal measurement model can be used to match the actual measurement result. When the third information indicates that the path is a non-visual path, a weaker signal measurement model can be used to match the actual measurement result, and thus it can be more accurately determined whether the path from the sensing object and / or the sensing area to the signal receiving device is a visual path or a non-visual path.

[0028] The second aspect provides a communication method, an execution subject of the method can be a path indication device, a component or device (for example, a processor, a chip, or a chip system) applied to the path indication device, or a logic module or software capable of realizing all or part of the functions of the path indication device. The communication method includes: first, sending first information used to determine a first path to a signal receiving device, the first path being at least one of the paths related to a sensing object and / or a sensing area; and then receiving second information used to indicate a measurement result corresponding to the first path.

[0029] In a second aspect, the first information and the second information are exchanged between the devices, so that the signal receiving device can provide the sensing device with the measurement result corresponding to the path of the sensing object and / or the sensing area, and the sensing purpose can be achieved.

[0030] In a possible design of the second aspect, the second information includes the measurement result of the first path; or the second information includes the measurement result of the first path and matching degree information, where the matching degree information is used to indicate the matching degree of the first path and the first information.

[0031] In this design, when the second information includes the measurement result of the first path, the signaling overhead required by the second information is smaller. When the second information includes the measurement result of the first path and the matching degree information, the matching degree of the first path and the first information can be determined based on the second information.

[0032] In a possible design of the second aspect, the first information is acquired by receiving the first information from the sensing network element.

[0033] In this design, the path indicating device is the sensing network element, the first information is provided by the sensing network element to the signal receiving device, and then the first information can be used to determine the second information.

[0034] In a possible design of the second aspect, the first information indicates a first angle interval; or the first information indicates a second angle interval. Optionally, when the first information indicates the first angle interval, the first path includes a path with an angle of arrival in the first angle interval; or when the first information indicates the second angle interval, the first path includes a path with a difference in angle of arrival from a preset first angle in the second angle interval.

[0035] In this design, the first information is designed to indicate an expected angle, for example, the first angle interval or the second angle interval, and the first path can be determined based on the expected angle.

[0036] In a possible design of the second aspect, the first information indicates a first time interval; or the first information indicates a second time interval. Optionally, when the first information indicates the first time interval, the first path includes a path with a time of arrival in the first time interval; or when the first information indicates the second time interval, the first path includes a path with a difference in time of arrival from a preset first time in the second time interval.

[0037] In this design, the first information is designed to indicate an expected time, for example, the first time interval or the second time interval, and the first path can be determined based on the expected time.

[0038] With reference to the second aspect, in a possible design, the method further includes: sending a signal, the signal being used for sensing the sensing object and / or the sensing area; or receiving a signal, the signal being used for sensing the sensing object and / or the sensing area.

[0039] In this design, the path indication apparatus is a signal sending apparatus, or the path indication apparatus is a signal receiving apparatus.

[0040] With reference to the second aspect, in a possible design, the second information is further used to indicate that the path of the signal from the sensing object and / or the sensing area to the signal receiving apparatus is a line-of-sight path, or the second information is further used to indicate that the path of the signal from the sensing object and / or the sensing area to the signal receiving apparatus is a non-line-of-sight path.

[0041] In this design, the second information is further used to indicate whether the path of the signal from the sensing object and / or the sensing area to the signal receiving apparatus is a line-of-sight path or a non-line-of-sight path, which more accurately indicates whether the path of the signal from the sensing object and / or the sensing area to the signal receiving apparatus is a line-of-sight path or a non-line-of-sight path, and improves sensing accuracy.

[0042] With reference to the second aspect, in a possible design, the method further includes: sending third information, the third information being used to indicate that the path of the signal from the signal sending apparatus to the sensing object and / or the sensing area is a line-of-sight path, or the third information being used to indicate that the path of the signal from the signal sending apparatus to the sensing object and / or the sensing area is a non-line-of-sight path.

[0043] In this design, after receiving the third information, the signal receiving apparatus can determine a measurement model used when performing signal measurement based on the third information. For example, when the third information indicates that the path is a line-of-sight path, a measurement model for strong signals can be used to match actual measurement results. When the third information indicates that the path is a non-line-of-sight path, a measurement model for weak signals can be used to match actual measurement results, and thus the path of the sensing object and / or the sensing area to the signal receiving apparatus can be more accurately determined to be a line-of-sight path or a non-line-of-sight path.

[0044] With reference to the second aspect, in a possible design, the first information is further used to indicate the at least one sensing object and / or the sensing area; and the second information is used to indicate measurement results corresponding to first paths corresponding to the at least one sensing object and / or the sensing area.

[0071] The network architecture and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0072] Before introducing the embodiments of the present application, some terms related to the embodiments of the present application are explained.

[0073] Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS): In wireless communication and positioning technology, understanding the concepts of LOS and NLOS is crucial for improving positioning accuracy and reliability.

[0074] LOS: In the LOS condition, the signal propagation path is straight, i.e., there is no obstacle blocking between the transmitting point and the receiving point. This propagation mode usually has the smallest path loss and the highest signal quality.

[0075] NLOS: In contrast to LOS, under NLOS conditions, the signal propagation path is blocked by obstacles, and the signal reaches the receiving point through reflection, scattering, or diffraction. This can cause problems such as signal attenuation, multipath effects, and time delay spread, which can affect positioning accuracy.

[0076] LOS indicator: In order to improve positioning accuracy, the system needs to know which measurement results are based on LOS paths and which are based on NLOS paths. Because in traditional positioning scenarios, LOS paths are usually more reliable than NLOS paths, giving LOS paths higher weights in positioning algorithms can improve positioning accuracy. The LOS indicator is an indicator that identifies the probability of whether a measurement path is an LOS path. For example, the LOS indicator can use 1-bit information to represent it, where 0 indicates a higher probability of an LOS path, and 1 indicates a higher probability of an NLOS path.

[0077] Primary path and multipath: In the fields of wireless communication, radar, sonar, and many other fields involving signal propagation, signals often do not propagate along a direct path from the transmitting point to the receiving point, but can arrive through multiple paths. Among these paths, some are formed by direct signal propagation (i.e., the so-called "primary path" or "line-of-sight path"), while others are formed by reflection, refraction, or diffraction of signals after encountering obstacles such as buildings, mountains, atmospheric layers, etc., which are called "multipath".

[0078] Sensing Function (SF) network element: A new type of network element involved in the 5th generation (5G) mobile communication system evolution (5G-Advanced, 5G-A / 5.5G) converged sensing network architecture. This network element has main sensing functions, including sensing control functions and sensing computing functions. It can exist independently or be combined with other network elements, and can be deployed in a centralized or distributed manner. The SF network element can perform tasks such as selection of sensing devices, control of sensing services, and processing of measurement data (measurement results) of sensing scenarios independently or jointly with other network elements. These functions make the SF network element play an important role in the converged sensing network, helping to upgrade the capabilities of wireless and network, and meet the requirements of diversified converged sensing scenarios and sensing service requirements.

[0079] Among them, the measurement data of the sensing scenario refers to various information data about the environment, objects or other objects collected by the sensing device in various sensing scenarios. These data can be physical quantities, chemical quantities, biological quantities, etc., and are used to realize functions such as monitoring, identification, and positioning of target objects.

[0080] In the positioning scenario, the request and reporting of measurement results are usually dominated by the first path. This is because the first path (line-of-sight path or direct path) provides the shortest and most direct propagation path from the transmission point to the receiving point. This path usually has the smallest propagation delay and the most stable signal characteristics, and is therefore more reliable and accurate in calculating location information. Alternatively, the base station or user equipment can also report a certain number of multipaths on this basis. Unlike the positioning scenario, the measurement results of interest in the perception scenario are generally not the first path, but the measurement results of the multipath reflected by a certain area or object. For example, the terminal measures 20 multipaths, and selects and reports the measurement results of the 10 multipaths with the strongest signal or the earliest time of arrival. However, the reflected path of a certain area or object of interest in the perception scenario may not be among the 10 multipaths.

[0081] At this time, it is difficult to achieve the purpose of perception based on the 10 multipath measurement results. That is, as described in the background, the traditional measurement and reporting method cannot be directly applied to the perception technology.

[0082] To solve the above technical problems, the embodiment of the present application provides a communication method, which is described below in conjunction with the accompanying drawings of the specification.

[0083] The communication method provided by the embodiment of the present application can be applied to various communication systems, such as a long term evolution (LTE) system, a 5G mobile communication system, a wireless fidelity (WiFi) system, a future communication system, or a system integrating multiple communication systems, etc., without limitation. The 5G can also be referred to as new radio (NR).

[0084] The communication method provided by the embodiments of the present application can be applied to various communication scenarios, for example, can be applied to one or more of the following communication scenarios: enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC), machine type communication (MTC), massive machine type communication (mMTC), device to device (D2D), vehicle to everything (V2X), vehicle to vehicle (V2V), and internet of things (IoT), etc.

[0085] The communication method provided by the embodiments of the present application will be described below taking the communication system shown in FIG. 1 as an example.

[0086] FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present application, as shown in FIG. 1, the communication system can include:

[0093] It should be understood that the signal transmitting device 110 and the signal receiving device 120 can be the same device or different devices. For example, in a self-transmit and self-receive (STSR) scenario, one device transmits and receives wireless signals simultaneously, in which case the signal transmitting device 110 and the signal receiving device 120 are the same device. For another example, in a point-to-point communication scenario, different devices play the roles of signal transmitter and signal receiver, in which case the signal transmitting device 110 and the signal receiving device 120 are different devices. In addition, the naming of the devices is not limited in the present disclosure, and alternatively, the signal transmitting device 110, the signal receiving device 120, the path indicating device 130, and the sensing device 140 can be collectively referred to as a communication device or other names.

[0099] The network equipment in the access network is mainly used to implement at least one of the functions of resource scheduling of the terminal, wireless resource management, and wireless resource control. Specifically, the network equipment in the access network can include any one of a base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), and some other access node. In the embodiments of the present application, the device for implementing the function of the network equipment can be a network equipment, or can be a device capable of supporting the network equipment to implement the function, such as a chip system, which can be installed in the network equipment or used in matching with the network equipment.

As shown in FIG. 2, in the communication system, a base station 210 is responsible for sending signals as a signal sending device, and the signals reach a terminal 220 along a first path and multiple paths. The terminal 220 is responsible for receiving the signals reaching through different paths as a signal receiving device.

[0102] An SF network element 230 plays the role of a path indicating device and a sensing device. The SF network element 230 is responsible for sending first information to the terminal 220, and the first information is used to indicate at least one path in a path related to a sensing object and / or a sensing area. After receiving the first information, the terminal 220 performs corresponding measurement, and feeds back a measurement result corresponding to the path indicated by the first information to the SF network element 230.

[0103] After receiving the measurement result from the terminal 220, the SF network element 230 performs sensing analysis based on the data, so as to achieve various application purposes such as target detection and tracking, environment monitoring, and action monitoring.

[0104] It should be noted that FIG. 2 is only an exemplary framework diagram, and the number of nodes included in FIG. 2 and the state of the terminal are not limited.

[0105] With the above-described communication system, the embodiment of the present application provides a communication method. The signal receiving device first acquires the first information from the path indicating device, and then sends the second information to the sensing device based on the first information. The first information can be used to determine at least one path related to the sensing object and / or the sensing area, referred to as the first path, and the second information indicates the measurement result corresponding to the first path. Through the interaction of the above-mentioned first information and the second information between the devices, the signal receiving device can provide the sensing device with the measurement result corresponding to the path related to the sensing object and / or the sensing area, thereby achieving the sensing purpose.

[0106] The communication method provided by the embodiment of the present application is described below from the perspective of the logic of each step. FIG. 3 shows a flowchart of the communication method provided by the embodiment of the present application. As shown in FIG. 3, the method can include the following steps:

[0107] S310, the path indicating device sends the first information for determining the first path to the signal receiving device, and correspondingly, the signal receiving device receives the first information for determining the first path from the path indicating device.

[0108] According to the introduction of the path indicating device in the embodiment of the present application, the path indicating device can be a network device in the access network or the core network. For example, a base station or an SF network element. That is, the signal receiving device can acquire the first information from the network device in the access network or the core network, and the first information is used to determine the first path, which is at least one path related to the sensing object and / or the sensing area. In one possible interpretation, the first path can also be interpreted as the expected path between the signal receiving device and the sensing object and / or the sensing area to be measured. The path indicating device can acquire the first information, for example, the first information can be configured in the path indicating device by human, or the first information can be indicated to the path indicating device by other network elements (such as the sensing device). In one possible interpretation, the first path can also be referred to as at least one path of the multipath passing through the sensing object and / or the sensing area.

[0109] The first information can be designed as information such as the angle and / or time of the sensing object and / or the sensing area. The present application will further describe the first information after step S320, which will not be described in detail here.

[0110] The sensing object can refer to a target or entity that needs to be monitored or tracked. The sensing object can be any thing with physical or virtual existence, such as a person, a vehicle, a device, a building, etc. The sensing object can be static or dynamic, depending on the requirements of the application scenario, which is not limited.

[0111] The perception area can refer to a specific geographical or logical area where the perception activity is performed. The area can be a part of physical space, such as a room, a street, or a city, or a logically defined range, such as a network coverage area or a data collection area. The size and shape of the perception area can be defined according to the requirements of the application scenario, without limitation.

[0112] It should be understood that the first information can also have other possible names, such as auxiliary information, reference information, etc.

[0113] S320, the signal receiving device sends second information for indicating the measurement result corresponding to the first path to the perception device, and correspondingly, the perception device receives the second information for indicating the measurement result corresponding to the first path from the signal receiving device.

[0114] Wherein, when the signal receiving device receives the signal sent by the signal sending device through the first path and / or the multipath, the signal receiving device can perform measurement based on the received signal to obtain the measurement result. For example, the signal receiving device can perform measurement by at least one of the following measurement methods 1-4, and then obtain the measurement result corresponding to each path signal respectively:

[0115] Method 1. Time of arrival (TOA) measurement:

[0116] The distance is inferred by measuring the time of arrival of the signal. This method is commonly used in positioning systems such as global positioning system (GPS). In the phase offset acquisition method, correlation operation is used, and the requirement for frequency synchronization is higher.

[0117] Method 2. Time difference of arrival (TDOA) measurement: TDOA is obtained by measuring TOA and subtracting, and the position is calculated according to the geometric principle. This method does not require strict time synchronization, but the technical complexity is higher.

[0118] Method 3. Angle-of-arrival (AOA) measurement: the angle of arrival of the signal is measured by using a directional antenna or an antenna array, so as to perform positioning.

[0119] Method 4. Received signal strength measurement: the signal quality or position estimation is evaluated by measuring the received signal strength (such as received signal strength, reference signal received power, etc.).

[0120] Based on a specific implementation scenario, the signal receiving device can flexibly adopt any one or more of the above measurement methods for measurement, or adopt other measurement methods for measurement, which is not limited. In addition, the specific measurement process can refer to the description of related technologies, and the present application will not be described here.

[0121] After the signal receiving device measures the measurement results corresponding to each path signal respectively, the second information can be determined based on the first information, and the second information is sent to the sensing device, which is used to indicate the measurement result corresponding to the first path introduced in step S310. Exemplarily, the second information can include the measurement result of the first path. Alternatively, the second information can include the measurement result of the first path and the matching degree information, which is used to indicate the matching degree of the first path and the first information, wherein the matching degree information can be determined based on the measurement result of the first path and the first information, and the specific determination process will be introduced in combination with the first information after the first information is described, which will not be described here.

[0122] In the embodiment of the present application, the signal receiving device first obtains the first information from the path indicating device, and then sends the second information to the sensing device based on the first information, the first information can be used to determine at least one path related to the sensing object and / or the sensing area, which is called the first path, and the second information indicates the measurement result corresponding to the first path. Through the interaction of the above first information and second information between each device, the signal receiving device can provide the sensing device with the measurement result corresponding to the path related to the sensing object and / or the sensing area, and then the sensing purpose can be achieved.

[0123] As described above, the first information and the second information are introduced as follows:

[0124] In an embodiment, the first information can indicate a first angle interval, the first path includes a path with an angle of arrival within the first angle interval, or the first path includes a path with an angle of arrival within the first angle interval and a path with an angle of arrival not within the first angle interval. In this scenario, the signal receiving device can use angle of arrival measurement, and the measurement result is the angle of arrival of each path.

[0125] Preferably, when the first path includes a path with an angle of arrival within the first angle interval, the second information can include the measurement result of the first path. Exemplarily, assuming that the first angle interval (hereinafter referred to as range1) is 45°±2°, the measured angle of arrival of path A is 45°, and the measured angle of arrival of path B is 42°, then path A meets the first angle interval, and path B does not meet the first angle interval, at this time, path B is not the first path, and path A is the first path. The second information at this time includes the measurement information of path A, and does not include the measurement information of path B.

[0126] When the first paths include paths with an angle of arrival within the first angle interval and paths with an angle of arrival not within the first angle interval, the second information can include measurement results of the first paths and matching degree information indicating a matching degree of the first paths with the first information. In this case, the angle of arrival of each path is compared with the first angle interval to determine the matching degree information of each path. For example, as shown in FIG. 4, assuming that range1: 45°±2°, the angle of arrival of path A is measured as 48°, and the angle of arrival of path B is measured as 42°, both path A and path B are the first paths. At this time, the absolute value of 48° minus 45° can be taken as the matching degree information of path A (hereinafter referred to as degree-A), which is expressed by the formula: degree-A = |48°-45°| = |3°|; and the absolute value of 42° minus 45° can be taken as the matching degree information of path B (hereinafter referred to as degree-B), which is expressed by the formula: degree-B = |42°-45°| = |-3°|, at this time, the smaller the value of the matching degree information, the more matched the path is with the first information. The second information includes the measurement results of path A and path B and the matching degree information.

[0127] It should be understood that the above-described manner of determining the matching degree information is an example, and other manners can be designed to determine the matching degree information in specific implementation, which is not limited.

[0128] In an embodiment, the first information can further indicate a second angle interval, the first paths include paths with an angle of arrival difference (hereinafter referred to as angle difference) from the preset first angle within the second angle interval, or the first paths include paths with an angle of arrival difference from the preset first angle within and not within the second angle interval. At this time, the second angle interval can be understood as an interval that limits the relative angle. The first angle can be flexibly set, for example, it can be set as the angle of arrival of the first path. For another example, when the signal is continuously measured, the angle of arrival of a certain path measured before can be set as the first angle, which is not limited. In this case, similar to when the first information indicates the first angle interval, the signal receiving device can use the angle of arrival measurement, and the measurement result is the angle of arrival of each path.

[0129] Preferably, when the first paths include paths with angle differences within the second angle interval, the second information can include the measurement results of the first paths. For example, as shown in FIG. 5, assuming that the first angle is the angle of arrival of the first path, the second angle interval (hereinafter referred to as range2) is an absolute value of the angle difference (hereinafter referred to as Δ1) ≤ 5°, the expression is range2: |Δ1|≤5°, the angle difference measured by path A is 8°, and the angle difference measured by path B is 1°, path A does not meet the first angle interval, and path B meets the first angle interval. At this time, path A is not the first path, and path B is the first path. The second information at this time includes the measurement information of path B and does not include the measurement information of path A.

[0130] When the first paths include paths with angle differences within the second angle interval and paths with angle differences not within the second angle interval, the second information can include the measurement results of the first paths and matching degree information indicating the matching degree of the first paths with the first information. At this time, the angle differences of the angles of arrival of the paths with respect to the first angle are compared with the second angle interval to determine the matching degree information of the paths. For example, assuming that range2: |Δ1|≤5°, the angle difference measured by path A is 8°, and the angle difference measured by path B is 1°, both path A and path B are the first paths, the absolute value of 8° can be used as the matching degree information of path A, and the absolute value of 1° can be used as the matching degree information of path B. At this time, the smaller the value of the matching degree information, the more matched the path is with the first information. The second information includes the measurement results of path A and path B and the matching degree information.

[0131] In an embodiment, the first information indicates a first time interval, the first paths include paths with arrival times within the first time interval, or the first paths include paths with arrival times within the first time interval and paths with arrival times not within the first time interval. In this case, the signal receiving device can use arrival time measurement, and the measurement result is the arrival time of each path.

[0132] Preferably, when the first paths include paths with arrival times within the first time interval, the second information can include the measurement results of the first paths. For example, as shown in FIG. 6, assuming that the first time interval (hereinafter referred to as range3) is T1±5 nanoseconds (ns), the arrival time measured by path A is ta=T1+2 ns, and the arrival time measured by path B is tb=T1+6 ns, path A meets the first time interval, and path B does not meet the first time interval. At this time, path B is not the first path, and path A is the first path. The second information at this time includes the measurement information of path A and does not include the measurement information of path B.

[0133] When the first paths include paths with arrival times within the first time interval and paths with arrival times not within the first time interval, the second information can include measurement results of the first paths and matching degree information indicating matching degrees of the first paths with the first information. In this case, the arrival times of the paths are compared with the first time interval to determine the matching degree information of the paths. For example, assuming that range3: T1±5ns, the arrival time measured by path A is ta=T1+2ns, and the arrival time measured by path B is tb=T1+6ns, both path A and path B are the first paths. At this time, the absolute value of T1+2 minus T1 can be taken as the matching degree information of path A, which is expressed by the formula: degree-A=|T1+2-T1|=|2|; the absolute value of T1+6 minus T1 can be taken as the matching degree information of path B, which is expressed by the formula: degree-B=|T1+6-T1|=|6|. At this time, the smaller the value of the matching degree information, the more matched the path is with the first information. The second information includes the measurement results of path A and path B and the matching degree information.

[0134] It should be understood that the first time interval and the arrival time are described by taking the time unit as nanoseconds in the present application, and other time granularities can be designed based on the needs of the scene in the specific implementation, which is not limited.

[0135] In an embodiment, the first information can also indicate a second time interval, and the first paths include paths with time differences (hereinafter referred to as time differences) of arrival times relative to a preset first time within the second time interval, or the first paths include paths with time differences of arrival times relative to a preset first time within and not within the second time interval. At this time, the second time interval can be understood as an interval that limits the relative time. The first time can be flexibly set, for example, it can be set as the arrival time of the first path. For another example, when the signal is continuously measured, the arrival time of a certain path measured before the signal can be set as the first time, which is not limited. In this case, similar to when the first information indicates the first time interval, the signal receiving device can use the arrival time measurement, and the measurement result is the arrival time of each path. For example, as shown in FIG. 7, assuming that the second time interval is ≤2ns, the time difference measured by path A is 3ns, and the time difference measured by path B is 1ns, path A does not meet the second time interval, and path B meets the second time interval. At this time, path A is not the first path, and path B is the first path. The second information at this time includes the measurement information of path B, and does not include the measurement information of path A.

[0136] Preferably, when the first paths include paths with time differences within the second time interval, the second information can include the measurement results of the first paths. For example, assuming that the second time interval (hereinafter referred to as range4) is |Δ2|≤2ns, the path A measures a time difference of 3ns, and the path B measures a time difference of 1ns, the path A does not meet the first time interval, and the path B meets the first time interval. In this case, the path A is not the first path, and the path B is the first path. The second information includes the measurement information of the path B, but does not include the measurement information of the path A.

[0137] When the first paths include paths with time differences within the second time interval and paths with time differences not within the second time interval, the second information can include the measurement results of the first paths and the matching degree information indicating the matching degree of the first paths with the first information. In this case, the time difference between the arrival time of each path and the first time is compared with the second time interval to determine the matching degree information of each path. For example, assuming that range4: |Δ2|≤2ns, the path A measures a time difference of 3ns, and the path B measures a time difference of 1ns, both the path A and the path B are the first paths. In this case, the absolute value of 3ns can be used as the matching degree information of the path A, and the absolute value of 1ns can be used as the matching degree information of the path B. The smaller the value of the matching degree information, the more matched the path is with the first information. The second information includes the measurement results of the path A and the path B and the matching degree information.

[0138] In an embodiment, the matching degree information can also be used to determine which measurement results of the first paths are included in the second information. In this case, the second information can include the measurement results of at least one first path with higher matching degree information and the matching degree information. For example, assuming that the second information can include measurement results of ten first paths, the paths can be sorted based on the matching degree information, and the measurement results of the top ten paths with higher matching degree information are used as the content of the second information. In this case, the second information does not have to carry too much data, and the signaling overhead of transmitting the second information is small.

[0139] In an embodiment, when the first paths include paths with arrival angles within the first angle interval, or when the first paths include paths with angle differences within the second angle interval, or when the first paths include paths with arrival times within the first time interval, or when the first paths include paths with time differences within the second time interval, the second information can also include the measurement results of the first paths and the matching degree information described above, without limitation.

[0140] It can be seen from the above that the embodiments of the present application introduce the design of the first path and the content of the second information when the first information indicates the expected angle, such as the first angle interval or the second angle interval, and introduce the design of the first path and the content of the second information when the first information indicates the expected time, such as the first time interval or the second time interval. It should be understood that the first information can indicate the expected angle or the expected time alone, or can indicate both the expected angle and the expected time, in which case the first path can be a path that meets the expected angle and the expected time indicated by the first information, or the first path can be a path that meets at least one of the expected angle and the expected time indicated by the first information. That is, the above-mentioned multiple embodiments can be flexibly combined and applied, for example, the first information indicates the first angle interval and the first time interval, the first information indicates the first angle interval and the second time interval, the first information indicates the second angle interval and the first time interval, or the first information indicates the second angle interval and the second time interval, without limitation.

[0141] In the embodiments of the present application, the signal receiving device first obtains the first information from the path indicating device, and then sends the second information to the sensing device based on the first information. The first information can indicate the expected angle and / or the expected time, and then at least one path related to the sensing object and / or the sensing area, referred to as the first path, can be determined based on the expected angle and / or the expected time, and the second information indicates the measurement result corresponding to the first path. By interacting the above-mentioned first information and the second information between devices, the signal receiving device can provide the sensing device with the measurement result corresponding to the path related to the sensing object and / or the sensing area, and thus the sensing purpose can be achieved.

[0142] In an embodiment, in the scenario where there are multiple sensing objects and / or sensing areas, in order to enable the sensing device to distinguish which second information should be corresponded to different sensing objects and / or sensing areas, the first information is used to indicate at least one sensing object and / or sensing area, so that the signal receiving device can determine the second information corresponding to each sensing object and / or sensing area based on the first information. At this time, the second information can include the measurement result of the first path corresponding to each sensing object and / or sensing area. For example, in a certain sensing scene, there are a sensing object M and a sensing area N, at this time, the first information indicates the first path corresponding to the sensing object M, and indicates the first path corresponding to the sensing area N.

[0143] For example, the first information can include an identity (ID) of the at least one perception object and / or the perception area. After the signal receiving device receives the ID of the perception object and / or the perception area, the ID of the perception object and / or the perception area can be used as an index to distinguish the second information corresponding to each perception object and / or perception area.

[0144] It should be understood that, when there is only one perception object or one perception area, the first information can or can not indicate the perception object or the perception area, without limitation, because there is no need to distinguish different perception objects or perception areas.

[0145] In the embodiments of the present application, when there are multiple perception objects and / or perception areas, the first information can also indicate each perception object and / or perception area, which can be used to distinguish each perception object and / or perception area, so that the signal receiving device can determine the second information corresponding to each perception object and / or perception area based on the first information, and then send the second information to the perception device, so that the perception device can clearly determine the second information corresponding to each perception object and / or perception area, and thus achieve accurate perception.

[0146] In an embodiment, the signal receiving device and the signal sending device are the same device, the signal receiving device sends signals and receives echoes of the signals, that is, a self-transmitting and self-receiving scenario, and the first information indicates the first angle interval or the second angle interval. At this time, the signal receiving device can send signals and receive echoes of the signals based on the first angle interval or the second angle interval. For example, the first angle interval range1 is 45°±2°, and the beam angle of the signal receiving device can satisfy 45°±2° to achieve signal transmission. For another example, the second angle interval range2 is |Δ1|≤5°, and assuming that the preset first angle is 30°, the beam angle of the signal receiving device can satisfy 30°±5°.

[0147] In an embodiment, the second information is further used to indicate whether a path (referred to as a first sub-path) from the sensing object and / or the sensing area to the signal receiving device is a line-of-sight path or a non-line-of-sight path. The first path includes a path (referred to as a second sub-path) from the signal sending device to the sensing object and / or the sensing area and the first sub-path. The signal receiving device can determine whether the first sub-path is a line-of-sight path or a non-line-of-sight path by judging the measured multipath signals. For example, the signal receiving device can determine whether the first sub-path is a line-of-sight path or a non-line-of-sight path based on the reference signal received power (RSRP) of the received signal. If the RSRP is low, it indicates that the signal is weak, and at this time, the signal is likely to have been reflected once before reaching the signal receiving device, and the probability of determining that the first sub-path is a non-line-of-sight path is high. If the RSRP is high, it indicates that the signal is strong, and at this time, the signal is likely to have been directly reflected to the signal receiving device, and the probability of determining that the first sub-path is a line-of-sight path is high.

[0148] For example, as shown in FIG. 8, two first sub-paths in the first path are shown: first sub-path A and first sub-path B. It can be seen that the first sub-path A reaches the signal receiving device without refraction and is a line-of-sight path, while the first sub-path B reaches the signal receiving device with refraction and is a non-line-of-sight path. The second information corresponding to the first sub-path A indicates that the first sub-path A is a line-of-sight path, and the second information corresponding to the first sub-path B indicates that the first sub-path B is a non-line-of-sight path.

[0149] Specifically, the second information can include a probability that the first sub-path is a line-of-sight path (or a non-line-of-sight path).

[0150] Alternatively, the second information can include a probability of one reflection or a probability of two reflections of the first path. One reflection indicates that the signal reaches the signal receiving device after being reflected once by the sensing object and / or the sensing area. Two reflections indicate that the signal reaches the signal receiving device after being reflected twice by the sensing object and / or the sensing area.

[0151] In the embodiments of the present application, the second information is further used to indicate whether a path from the sensing object and / or the sensing area to the signal receiving device is a line-of-sight path or a non-line-of-sight path. Compared with the traditional indication of whether the complete path from the signal sending device to the signal receiving device is a line-of-sight path or a non-line-of-sight path, the present application more accurately indicates whether the path from the sensing object and / or the sensing area to the signal receiving device is a line-of-sight path or a non-line-of-sight path, and can improve the sensing accuracy.

[0152] In an embodiment, as shown in FIG. 9, the method can further include:

[0153] S330, the signal sending device sends the third information to the signal receiving device, and correspondingly, the signal receiving device receives the third information from the signal sending device.

[0154] The third information is used to indicate whether the path from the signal sending device to the sensing object and / or the sensing area is a visual path or a non-visual path. The signal sending device can determine the third information in a previous measurement process or manually configure the third information on the signal sending device. After receiving the third information, the signal receiving device can determine the measurement model used when performing signal measurement based on the third information. For example, when the third information indicates that the path is a visual path, a stronger signal measurement model can be used to match the actual measurement result. When the third information indicates that the path is a non-visual path, a weaker signal measurement model can be used to match the actual measurement result, so as to more accurately determine whether the path from the sensing object and / or the sensing area to the signal receiving device is a visual path or a non-visual path.

[0155] Optionally, the third information can also be sent by the sensing device to the signal sending device and forwarded by the signal sending device to the signal receiving device, which is not limited.

[0156] It can be understood that the step S330 can be combined with the step S310 and / or the step S320, or can be applied alone, that is, the communication method provided by the embodiment of the present application can include the step S330, the step S310 and the step S320, or the communication method provided by the embodiment of the present application includes the step S330 and the step S320, at this time, the second information is used to indicate whether the path (referred to as a first sub-path) from the sensing object and / or the sensing area to the signal receiving device is a visual path or a non-visual path, or the communication method provided by the embodiment of the present application includes the step S330, and the description of each step is described above and will not be repeated.

[0157] It can be understood that the step S330 can be combined with the step S310 and / or the step S320, or can be applied alone, that is, the communication method provided by the embodiment of the present application can include the step S330, the step S310 and the step S320, or the communication method provided by the embodiment of the present application includes the step S330 and the step S320, at this time, the second information is used to indicate whether the path (referred to as a first sub-path) from the sensing object and / or the sensing area to the signal receiving device is a visual path or a non-visual path, or the communication method provided by the embodiment of the present application includes the step S330, and the description of each step is described above and will not be repeated.

[0168] In the embodiments of the present application, the first information and the second information are exchanged between the devices, so that the signal receiving device can provide the sensing device with the measurement result corresponding to the path of the sensing object and / or the sensing area, and the sensing purpose can be achieved.

[0169] In an embodiment, the second information includes the measurement result of the first path, or the second information includes the measurement result of the first path and matching degree information, where the matching degree information is used to indicate the matching degree of the first path and the first information.

[0170] In this embodiment, when the second information includes the measurement result of the first path, the signaling overhead required by the second information is small. When the second information includes the measurement result of the first path and the matching degree information, the matching degree of the first path and the first information can be determined based on the second information.

[0171] In an embodiment, the obtaining module 111 is specifically configured to receive the first information from the sensing network element.

[0172] In this embodiment, the path indicating device is the sensing network element, and the sensing network element provides the signal receiving device with the first information, so that the first information can be used to determine the second information.

[0173] In an embodiment, the first information indicates a first angle interval, or the first information indicates a second angle interval. Optionally, when the first information indicates the first angle interval, the first path includes a path with an angle of arrival within the first angle interval, or when the first information indicates the second angle interval, the first path includes a path with a difference in angle of arrival from a preset first angle within the second angle interval.

[0178] In this embodiment, the signal receiving device is applicable to a self-transmitting and self-receiving scenario, and transmits a signal and receives an echo of the signal. Alternatively, the signal receiving device is applicable to a scenario in which different devices play the roles of a signal transmitter and a signal receiver, and the signal receiving device receives a signal.

[0179] In an embodiment, the transceiver module 112 is specifically configured to: transmit a signal and receive an echo of the signal based on a first angle interval, wherein the first information comprises the first angle interval; or transmit a signal and receive an echo of the signal based on a second angle interval, wherein the first information comprises the second angle interval.

[0180] In this embodiment, the signal receiving device transmits a signal and receives an echo of the signal, i.e., a self-transmitting and self-receiving scenario, and the first information indicates a first angle interval or a second angle interval. In this case, the signal receiving device transmits a signal based on the first angle interval or the second angle interval to emit the signal and receive an echo of the signal, so as to ensure that the signal can pass through a perception object and / or a perception area that needs to be perceived.

[0181] In an embodiment, the second information is further used to indicate that a path of a signal from a perception object and / or a perception area to the signal receiving device is a visual path, or the second information is further used to indicate that the path of the signal from the perception object and / or the perception area to the signal receiving device is a non-visual path.

[0182] In this embodiment, the second information is further used to indicate whether a path of a signal from a perception object and / or a perception area to the signal receiving device is a visual path or a non-visual path. Compared with a traditional indication of whether a complete path from a signal transmitting device to a signal receiving device is a visual path or a non-visual path, the indication of whether the path of the signal from the perception object and / or the perception area to the signal receiving device is a visual path or a non-visual path is more accurate, and the perception accuracy can be improved.

[0183] In an embodiment, the first information is further used to indicate at least one perception object and / or at least one perception area; and the second information is used to indicate a measurement result corresponding to a first path corresponding to each of the at least one perception object and / or the at least one perception area.

[0184] In this embodiment, when there are multiple sensing objects and / or sensing areas, the first information further indicates the sensing objects and / or sensing areas, which can be used to distinguish the sensing objects and / or sensing areas, so that the signal receiving device can determine the second information corresponding to each sensing object and / or sensing area based on the first information, and then send the second information to the sensing device, so that the sensing device can determine the second information corresponding to each sensing object and / or sensing area, and then achieve accurate sensing.

[0185] In an embodiment, the transceiver module 112 is further configured to receive third information from the signal sending device, the third information being used to indicate that the path from the signal sending device to the sensing object and / or sensing area is a line-of-sight path, or the third information being used to indicate that the path from the signal sending device to the sensing object and / or sensing area is a non-line-of-sight path.

[0186] In this embodiment, after receiving the third information, the signal receiving device can determine the measurement model used when performing signal measurement based on the third information. For example, when the third information indicates that the path is a line-of-sight path, a stronger signal measurement model can be used to match the actual measurement result. When the third information indicates that the path is a non-line-of-sight path, a weaker signal measurement model can be used to match the actual measurement result, so as to more accurately determine whether the path from the sensing object and / or sensing area to the signal receiving device is a line-of-sight path or a non-line-of-sight path.

[0192] In this embodiment, after receiving the third information, the signal receiving device can determine the measurement model to be used when performing signal measurement based on the third information. For example, when the third information indicates that the path is a line-of-sight path, a stronger signal measurement model can be used to match the actual measurement result. When the third information indicates that the path is a non-line-of-sight path, a weaker signal measurement model can be used to match the actual measurement result, so as to more accurately determine whether the path from the perceiving object and / or the perceiving area to the signal receiving device is a line-of-sight path or a non-line-of-sight path.
