Description

Information reporting method, configuration sending method, device, equipment and medium Technical Field

[0001] The present application relates to the field of communications, and in particular to an information reporting method, a configuration sending method, an apparatus, a device, and a medium. Background Art

[0002] One of the new technologies proposed by the 3GPP (Third Generation Partnership Project) is to integrate wireless sensing with mobile communications to achieve converged sensing communication services. Using higher frequency bands, wider bandwidths, and larger antenna arrays, the entire communication system can be used as a sensor to achieve high-precision, high-resolution perception.

[0003] Communication transmission can be categorized as single-carrier or multi-carrier. In multi-carrier transmission scenarios, each subcarrier has a different center frequency and corresponding wavelength. During the perception process, factors such as distance, speed, and multipath environment affect each subcarrier differently, meaning that information from different subcarriers contributes differently to the perception results. Therefore, selecting the subcarriers for perception in multi-carrier scenarios is a pressing issue.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide an information reporting method, a configuration sending method, an apparatus, a device, and a medium. The technical solutions are as follows:

[0006] According to one aspect of the present application, a method for reporting perception information is provided, the method being performed by a second node, the method comprising:

[0008] According to one aspect of the present application, a method for sending a perception signal configuration is provided, where the method is performed by a first node and includes:

[0009] A second perception signal configuration is sent to the second node, where the second perception signal configuration includes second information, where the second information is used to indicate a frequency domain unit.

[0010] According to one aspect of the present application, a device for reporting perceived information is provided, the device comprising:

[0011] The first sending module is used to send first information to the first node, where the first information is used to indicate a frequency domain unit that meets a first feature, and the first feature is a feature related to perception.

[0012] According to one aspect of the present application, a device for sending a perception signal configuration is provided, the device comprising:

[0013] The second sending module is configured to send a second perception signal configuration to the second node, where the second perception signal configuration includes second information, and the second information is used to indicate a frequency domain unit.

[0014] According to one aspect of the present application, a sensing device is provided, comprising:

[0015] A processor; a transceiver connected to the processor; a memory for storing executable instructions of the processor;

[0016] The processor is configured to load and execute the executable instructions to implement the above-mentioned method for reporting information for perception, or the above-mentioned method for sending perception signal configuration.

[0017] According to one aspect of the present application, a computer-readable storage medium is provided, in which at least one program is stored. The at least one program is loaded and executed by a processor to implement the above-mentioned information reporting method for perception, or the above-mentioned method for sending perception signal configuration.

[0018] According to one aspect of the present application, a chip is provided, which includes a programmable logic circuit and / or program instructions.

[0021] The second node is a perception node that receives the perception signal or a perception management node responsible for management. The second node can select a frequency domain unit that meets the first feature based on the features of the received perception signal and report it to the first node, so that the first node can understand the features of the frequency domain unit when sending subsequent perception signals and select a suitable frequency domain unit to send the perception signal, thereby avoiding poor perception effect caused by selecting an unsuitable frequency domain unit due to blind selection; or, the first node directly uses all frequency domain units for perception, which affects other signals, such as communication signals or signals sent by other users. After the second node sends the first information to the first node, the first node can send the perception signal based on the first information. The first information indicates the frequency domain unit that meets the first feature. Using the frequency domain unit indicated by the first information to send the perception signal instead of using the frequency domain units of the entire frequency domain to send the perception signal can improve resource utilization and save energy of the first node and the second node.

[0046] Before introducing the technical solutions of this application, we first introduce and explain some of the background technologies involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0047] FIG1 shows a block diagram of a perception system provided by an exemplary embodiment of the present application. The perception system may include: one or more perception nodes 10 and a perception target 20 .

[0048] The sensing nodes 10 include sensing sending nodes and sensing receiving nodes. They may include base stations, terminals, IoT (Internet of Things) devices, or various handheld devices with wireless communication capabilities, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to wireless modems, as well as various forms of user equipment, MSs (Mobile Stations), etc. There are usually multiple sensing nodes 10.

[0049] The sensing target 20 is the target object to be sensed, including the user equipment (UE), person, object, or area to be sensed. For example, if the sensing application is indoor intrusion monitoring, the sensing target 20 is the indoor intruder; if the sensing application is vehicle speed measurement, the sensing target 20 is the target vehicle on the road. If the sensing application is drone monitoring, the sensing target 20 is the drone device.

[0050] Optionally, the perception system also includes a perception control node 30, which can also be called a perception management node. The perception control node 30 is used to control and manage perception services, thereby improving perception efficiency. It can include base stations, terminals, IoT devices, or various handheld devices with wireless communication capabilities, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to wireless modems, as well as various forms of user equipment, mobile stations, etc. Optionally, the functions of the perception control node 30 include, but are not limited to: managing perception services, sending configuration information to perception nodes and / or perceived targets to configure the transmission / reception of perception measurement signals or the transmission / reception of perception signals, configuring perception nodes and / or perceived targets to report measurement results and / or perception results, and sending perception assistance information to perception nodes and / or perceived targets.

[0051] The perception node 10 and the perception control node 30 communicate with each other through communication signals.

[0052] As the spectrum for wireless communications and sensing gradually overlap, integrated communication and sensing technology merges these two functions, leveraging the wireless resources of wireless communications to implement sensing. The following is a brief introduction to integrated communication and sensing.

[0053] Communication and perception integration

[0054] Next-generation networks, such as 6G (Sixth Generation Mobile Communications), are expected to integrate mobile communication networks, perception networks, and computing networks. In a narrow sense, a perception network refers to a system capable of target positioning (ranging, speed, and angle measurement), target imaging, target detection, target tracking, and target recognition. In a broader sense, it refers to a system that understands the attributes and status of all services, networks, users, terminals, and environmental objects. From the perspective of perception applications, perception can be categorized as follows:

[0055] Outdoor / wide-area / local-area applications: including smart cities (e.g., weather monitoring), smart transportation / high-speed rail (e.g., high-precision map construction, road supervision, intrusion detection), and low-altitude applications (e.g., drone monitoring and obstacle avoidance, flight intrusion detection, flight path management).

[0056] Indoor / local applications: including smart home and health management (such as respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, and mobile trajectory tracking), smart factories (such as intrusion detection, material detection, and object defect detection), etc.

[0057] It should be noted that the above only shows the classification of some perception applications, but the classification and scope of perception applications are not limited to this.

[0058] Wireless communication and perception are two key applications of modern radio frequency technology. Perception uses radio waves to detect parameters of the physical environment, enabling environmental perception such as target location, motion recognition, and imaging. Traditionally, perception and wireless communication exist independently, and this separate design wastes wireless spectrum and hardware resources. With the advent of the Beyond Fifth Generation (B5G) and 6G eras, the communication spectrum is shifting towards millimeter-wave, terahertz, and visible light communications. The spectrum for future wireless communications will overlap with the spectrum for traditional perception. Integrated communication and perception technology merges wireless communication and perception, leveraging wireless resources for perception; enabling sensing services over a wider range using widely deployed cellular networks; achieving higher perception accuracy through joint perception using base stations and multiple terminals; and reusing wireless communication hardware modules for perception, reducing costs. In short, integrated communication and perception technology empowers future wireless communication systems with perception capabilities, providing a foundation for the development of smart transportation, smart cities, smart factories, drones, and other services.

[0059] Nodes and / or entities involved in perception include but are not limited to:

[0060] Sensing sending node: the sending node of the sensing signal.

[0061] Sensing receiving node: a receiving node that senses the signal.

[0062] Perception nodes: Perception sending nodes and perception receiving nodes are collectively referred to as perception nodes, that is, nodes that perform perception.

[0063] Perception can be achieved through at least one of eight modes. Figure 2 shows eight possible modes of perception.

[0064] Mode 1: Base station autonomous sensing. In Mode 1, the sensing sending node and the sensing receiving node are the same base station 41. Specifically, base station 41 transmits a sensing signal to sensing target 42. After the sensing signal is reflected by sensing target 42, the same base station 41 receives the reflected signal (i.e., the sensing signal after being reflected by the sensing target).

[0065] Mode 2: Terminal-based self-transmission and self-reception. In Mode 2, the sensing sending node and the sensing receiving node are the same terminal 43. That is, terminal 43 sends a sensing signal to sensing target 44. After the sensing signal is reflected by sensing target 44, the same terminal 43 receives the reflected signal.

[0066] Mode 3: Base station cooperative sensing. In mode 3, the sensing sending node and the sensing receiving node are different base stations. That is, one base station 45 sends a sensing signal to the sensing target 46. After the sensing signal is reflected by the sensing target 46, another base station 47 receives the reflected signal.

[0067] Mode 4: Terminal Collaborative Sensing. In Mode 4, the sensing sending node and the sensing receiving node are different terminals. That is, one terminal 48 sends a sensing signal to a sensing target 49. After the sensing signal is reflected by the sensing target 49, another terminal 50 receives the reflected signal.

[0068] Mode 5: Base station-terminal collaborative sensing. In Mode 5, the sensing sending node is base station 51, and the sensing receiving node is terminal 53. Specifically, base station 51 sends a sensing signal to sensing target 52. After the sensing signal is reflected by sensing target 52, terminal 53 receives the reflected signal.

[0069] Mode 6: Terminal-Base Station Collaborative Sensing. In Mode 6, the sensing sending node is terminal 54, and the sensing receiving node is base station 56. Specifically, terminal 54 sends a sensing signal to sensing target 55. After the sensing signal is reflected by sensing target 55, base station 56 receives the reflected signal.

[0070] Mode 7: The sensing target is the sensing sending node. In Mode 7, the sensing sending node is terminal 57, and the sensing receiving node is base station 58. Because the sensing target (terminal 57) is the sensing sending node, the sensing signal is sent from the sensing sending node (terminal 57) to the sensing receiving node (base station 58) without reflection. Base station 58 can directly receive and interpret the sensing result.

[0071] Mode 8: The sensing target is the sensing receiving node. In Mode 8, the sensing sending node is base station 59, and the sensing receiving node is terminal 60. Since the sensing target (terminal 60) is the sensing receiving node, after receiving the sensing signal, terminal 60 needs to feed back the sensing result to base station 59, so that base station 59 can obtain the sensing result.

[0072] In the eight sensing modes shown in Figure 2, there is only a single sensing node (for example, in modes 1 and 2, a single node is both a sensing sending node and a sensing receiving node) or a pair of sensing nodes (for example, in modes 3 through 8, the sensing sending node and the sensing receiving node are different paired nodes). However, in wireless communication systems, there are a large number of terminal devices (for example, mobile phones, IoT devices, etc.). When multiple sensing nodes (including sensing sending nodes and sensing receiving nodes, i.e., base stations, mobile phones, IoT devices, etc. that send and / or receive sensing signals) are present around a sensing target, the joint participation of multiple sensing nodes in sensing can improve the accuracy of sensing, meet the needs of more complex sensing services, and provide richer sensing services. When there are multiple sensing nodes in the system, a sensing control node may be present to control and manage the entire sensing service to improve efficiency. This sensing control node can be a base station, a terminal, or a core network element.

[0073] Multi-carrier sensing system

[0074] Multi-carrier sensing refers to the use of a multi-carrier transmission scheme to transmit sensing signals during the sensing process. OFDM (Orthogonal Frequency-Division Multiplexing) signals are widely used in NR (New Radio) communication systems. OFDM technology is one of the implementation methods of multi-carrier transmission schemes. It divides the channel into several orthogonal sub-channels, converts high-speed data signals into parallel low-speed sub-data streams, and modulates them for transmission on each sub-channel. In an integrated communication and sensing system, the use of the OFDM signal format can make sensing in the communication system easier to implement. Perception in the communication system is achieved by multiplexing the sensing (reference) signal into the OFDM signal in the communication system, and the perception result is obtained based on the channel information of each sub-carrier where the sensing (reference) signal is located in the OFDM signal.

[0075] Each subcarrier in an OFDM signal has a different center frequency and corresponding wavelength. Therefore, during the perception process, factors such as distance, speed, and multipath environment affect each subcarrier differently. During perception, the information from different subcarriers contributes differently to the perception result. Some subcarriers clearly exhibit the signal characteristics required for perception, while others are less so. During the perception process, using only subcarriers that clearly exhibit the perceived signal characteristics can achieve accurate perception results and eliminate the influence of other subcarriers. Therefore, subcarrier screening is an effective method for improving performance and efficiency in the perception process.

[0076] FIG3 shows a flow chart of a method for reporting perceived information provided by an exemplary embodiment of the present application. The method is executed by the second node, and the method includes:

[0077] Step 210: Send first information to the first node, where the first information is used to indicate a frequency domain unit that meets a first feature, where the first feature is a feature related to perception.

[0078] A frequency domain unit is the basic unit for dividing the frequency domain. For example, a frequency domain unit is an RB (Resource Block) or a subcarrier. The frequency domain units that meet the first characteristic are a portion of all frequency domain units in the full bandwidth, or a portion of all frequency domain units that carry perception signals.

[0079] In some embodiments, the frequency domain unit that meets the first characteristic is selected by the second node; or, the frequency domain unit that meets the first characteristic is selected by the perception receiving node; or, the frequency domain unit that meets the first characteristic is selected by the perception control node; or, the frequency domain unit that meets the first characteristic is selected by the perception management node.

[0080] The first feature is a feature related to perception. Alternatively, it can be said that the first feature is a feature that facilitates perception. Alternatively, it can be said that the first feature is a feature that is sensitive to perception, or that is sensitive to perceptual signals. The first feature is described in "(1) First Feature" below and will not be further described here.

[0081] In summary, the method provided in the embodiment of the present application shows that the second node sends a frequency domain unit that meets the first feature to the first node. The second node is a sensing node that receives the sensing signal or a sensing management node responsible for management. The second node can select a frequency domain unit that meets the first feature based on the characteristics of the received sensing signal and report it to the first node, so that the first node can understand the characteristics of the frequency domain unit when sending the subsequent sensing signal and select an appropriate frequency domain unit to send the sensing signal, thereby avoiding the selection of a frequency domain unit that is not suitable for sensing due to blind selection, resulting in poor sensing effect; or, the first node does not select and directly uses all frequency domain units for sensing, resulting in affecting other signals, such as communication signals or signals sent by other users. After the second node sends the first information to the first node, the first node can send the sensing signal based on the first information. The first information indicates the frequency domain unit that meets the first feature. Using the frequency domain unit indicated by the first information to send the sensing signal instead of using the frequency domain units of the entire frequency domain to send the sensing signal can improve resource utilization and save energy for the first and second nodes.

[0082] FIG4 shows a flow chart of a method for sending a perception signal configuration according to an exemplary embodiment of the present application. The method is executed by the first node, and the method includes:

[0083] Step 310: Send a second sensing signal configuration to the second node, where the second sensing signal configuration includes second information, and the second information is used to indicate a frequency domain unit.

[0084] In some embodiments, the second information is used to indicate a frequency domain unit that meets the first characteristic. In other words, the second information is used to indicate a frequency domain unit, and the frequency domain unit indicated by the second information is a frequency domain unit that meets the first characteristic.

[0085] A frequency domain unit is a basic unit for dividing the frequency domain. For example, a frequency domain unit is an RB or a subcarrier. The frequency domain unit indicated by the second information is a portion of the frequency domain units of the full bandwidth, or a portion of the frequency domain units of all frequency domain units that carry perception signals.

[0086] The first feature is a feature related to perception. Alternatively, it can be said that the first feature is a feature that facilitates perception. Alternatively, it can be said that the first feature is a feature that is sensitive to perception, or that is sensitive to perceptual signals. The first feature is described in "(1) First Feature" below and will not be further described here.

[0087] In summary, in the method provided in the embodiment of the present application, the first node sends a second perception signal configuration to the second node, and the second perception signal configuration includes second information for indicating a frequency domain unit that meets the first characteristic. Informing the second node that it needs to detect the perception signal on the frequency domain unit indicated by the second information can eliminate the need for the second node to perform perception detection on all frequency domain units, thereby reducing the energy consumption of the second node and the complexity of information reception at the second node. The first node and the second node agree on the frequency domain unit for sending the perception signal through configuration, that is, agree on the frequency domain unit that participates in perception, which can reduce the complexity of the second node's reception as much as possible. The second node does not need to distinguish whether the signal on each frequency domain unit is a perception signal, and only needs to perceive on the frequency domain unit indicated by the second information.

[0088] In the optional embodiment based on FIG. 3 or FIG. 4 , the first feature is described in detail.

[0089] (1) First characteristic

[0090] In some embodiments, the first feature includes at least one of the following features:

[0091] First correlation type;

[0092] Second correlation type;

[0093] The first parameter change type;

[0094] The second parameter change type;

[0095] The first parameter variance type;

[0096] The second parameter variance type;

[0097] The correlation is greater than a first correlation threshold;

[0098] The correlation is less than a second correlation threshold;

[0099] The parameter change is greater than the first parameter threshold;

[0100] The parameter change is less than the second parameter threshold;

[0101] The parameter change variance is greater than the first variance threshold;

[0102] The parameter change variance is less than the second variance threshold.

[0103] Among them, the correlation of the first correlation type is higher than the correlation of the second correlation type; the parameter change of the first parameter change type is higher than the parameter change of the second parameter type; the parameter change variance of the first parameter change variance type is higher than the parameter change variance of the second parameter change variance type; the first correlation threshold is greater than or equal to the second correlation threshold; the first parameter threshold is greater than or equal to the second parameter threshold; the first variance threshold is greater than or equal to the second variance threshold.

[0104] In some embodiments, the first correlation type and the second correlation type are determined based on a third correlation threshold; the first parameter change type and the second parameter change type are determined based on a third parameter threshold; the first parameter change variance type and the second parameter change variance type are determined based on a third variance threshold.

[0105] Next, it is shown how to determine the type based on the threshold.

[0106] For example, when the correlation of the frequency domain unit is greater than or equal to the third correlation threshold, the frequency domain unit is of the first correlation type; when the correlation of the frequency domain unit is less than the third correlation threshold, the frequency domain unit is of the second correlation type. Alternatively, when the correlation of the frequency domain unit is greater than the third correlation threshold, the frequency domain unit is of the first correlation type; when the correlation of the frequency domain unit is less than or equal to the third correlation threshold, the frequency domain unit is of the second correlation type.

[0107] For example, when the parameter change of the frequency domain unit is greater than or equal to the third parameter threshold, the frequency domain unit is of the first parameter type; when the parameter change of the frequency domain unit is less than the third parameter threshold, the frequency domain unit is of the second parameter type. Alternatively, when the parameter change of the frequency domain unit is greater than the third parameter threshold, the frequency domain unit is of the first parameter type; when the parameter change of the frequency domain unit is less than or equal to the third parameter threshold, the frequency domain unit is of the second parameter type.

[0108] For example, when the parameter change variance of the frequency domain unit is greater than or equal to the third variance threshold, the frequency domain unit is of the first parameter change variance type; when the parameter change variance of the frequency domain unit is less than the third variance threshold, the frequency domain unit is of the second variance type. Alternatively, when the parameter change variance of the frequency domain unit is greater than the third variance threshold, the frequency domain unit is of the first variance type; when the parameter change variance of the frequency domain unit is less than or equal to the third variance threshold, the frequency domain unit is of the second variance type.

[0109] In some embodiments, the correlation is greater than a first correlation threshold; the correlation is less than a second correlation threshold; the parameter change is greater than the first parameter threshold; the parameter change is less than the second parameter threshold; the parameter change variance is greater than the first variance threshold; and the parameter change variance is less than the second variance threshold. For the above situations, when the first correlation threshold and the second correlation threshold are equal and the correlation is equal to the first correlation threshold, the first feature is considered to belong to the same class with a correlation greater than the first correlation threshold; or, the first feature is considered to belong to the same class with a correlation less than the first correlation threshold. When the first parameter threshold and the second parameter threshold are equal and the parameter change is equal to the first correlation threshold, the first feature is considered to belong to the same class with a parameter change greater than the first parameter threshold; or, the first feature is considered to belong to the same class with a parameter change less than the first parameter threshold. When the first variance threshold and the second variance threshold are equal and the parameter change variance is equal to the first variance threshold, the first feature is considered to belong to the same class with a parameter change variance greater than the first variance threshold; or, the first feature is considered to belong to the same class with a parameter change variance less than the first variance threshold. The term "equal" is not limited in this application.

[0110] Next, we will briefly introduce concepts such as correlation, parameter change, and parameter change variance.

[0111] In some embodiments, the correlation of the frequency domain unit is used to indicate the correlation of the channel corresponding to the frequency domain unit, which is obtained by performing a correlation operation on the channel corresponding to the frequency domain unit. The correlation operation of the channel is a measure of the similarity of two channels; the higher the correlation, the more similar the two frequency domain units or the channels corresponding to the two frequency domain units are; the lower the correlation, the greater the difference between the two frequency domain units or the channels corresponding to the two frequency domain units. Under normal circumstances, the channel will be affected by the environment in which it is located. When the two channels are in the same environment or a similar environment or in a static and unchanging environment, that is, when the environmental factors corresponding to the channels are the same or the environmental factors are similar or the environmental factors do not change, the correlation between the two channels is high; when the two channels are in different environments or a channel environment changes or multipath interference occurs, that is, when the environmental factors corresponding to the channels are different or the environmental factors change or multipath interference occurs, the correlation between the two channels is low.

[0112] In some embodiments, the first feature includes a first correlation type and a second correlation type, and the frequency domain units that meet the first feature are a plurality of frequency domain units of the second correlation type and one or a few frequency domain units of the first correlation type. This ensures the integrity of the perceived information while reducing the number of frequency domain units used to achieve dimensionality reduction for the processed data of the second node, thereby reducing the computational complexity of the second node.

[0113] In some embodiments, the parameter includes at least one of the amplitude, phase, real part, and imaginary part. The parameter change of the frequency domain unit refers to the parameter change when the signal is transmitted on different time domain units and the same frequency domain unit; or, the parameter change of the frequency domain unit refers to the parameter value of the channel change of the frequency domain unit. For example, the amplitude 1 of the perception signal when it is transmitted on {time domain unit 1, frequency domain unit 1} and the amplitude 2 of the perception signal when it is transmitted on {time domain unit 2, frequency domain unit 1} are measured respectively, and the difference between the amplitude 1 and the amplitude 2 is calculated as the amplitude change of the frequency domain unit 1. The parameter change of the frequency domain unit can also be described by CSI (Channel State Information).

[0114] By way of example and not limitation, the first parameter change type includes at least one of a first amplitude change type, a first phase change type, a first real part change type, and a first imaginary part change type; the second parameter change type includes at least one of a second amplitude change type, a second phase change type, a second real part change type, and a second imaginary part change type.

[0115] In some embodiments, the parameter change variance of the frequency domain unit refers to the variance of the parameter change of the signal in different time domain units in the same frequency domain unit.

[0117] In some embodiments, the above-mentioned threshold information such as the first correlation threshold, the second correlation threshold, the third correlation threshold, the first parameter threshold, the second parameter threshold, the third parameter threshold, the first variance threshold, the second variance threshold and the third procedure threshold is agreed upon by the communication protocol; or, is configured by the first node for the second node; or, is configured by the perception management node for the perception receiving node; or, is configured by the perception sending node for the perception receiving node.

[0118] In some embodiments, the first feature also includes at least one of a first signal quality type; a second signal quality type. The first signal quality type and the second signal quality type are determined based on a signal quality threshold. When the signal quality of the frequency domain unit is greater than or equal to the signal quality threshold, the frequency domain unit is of the first signal quality type; when the signal quality of the frequency domain unit is less than the signal quality threshold, the frequency domain unit is of the second signal quality type. Or, when the signal quality of the frequency domain unit is greater than the signal quality threshold, the frequency domain unit is of the first signal quality type; when the signal quality of the frequency domain unit is less than or equal to the signal quality threshold, the frequency domain unit is of the second signal quality type. The signal quality can be SNR (Signal-to-Noise Ratio) or SINR (Signal to Interference plus Noise Ratio).

[0119] (2) Distribution characteristics of frequency domain units that meet the first characteristic

[0120] In some embodiments, the frequency domain units indicated by the first information and / or the second information in the perception signal configuration meet at least one of the following conditions: non-continuous; equally spaced; and unequally spaced.

[0121] In some embodiments, the frequency domain units indicated by the first information and / or the second information in the perception signal configuration meet at least one of the following conditions: continuous; equally spaced; and unequally spaced.

[0122] In some embodiments, the combination of the above distribution features can be summarized as: discontinuous and unequally spaced; discontinuous and equally spaced; discontinuous; continuous and unequally spaced; continuous and equally spaced; continuous. The above distribution features are further described below with reference to the accompanying drawings.

[0123] Exemplarily, the distribution characteristics of the frequency domain units are discontinuous and unequally spaced. Discontinuous means that any two frequency domain units that meet the first characteristic are not adjacent; unequally spaced means that the interval between the i-th frequency domain unit that meets the first characteristic and the i+1-th frequency domain unit that meets the first characteristic is not a fixed value, and i is a positive integer. As shown in part (1) of Figure 5, frequency domain unit 0, frequency domain unit 4, and frequency domain unit 6 are not adjacent, that is, the distribution characteristics of the frequency domain units that meet the first characteristic are discontinuous. The interval between frequency domain unit 0 and frequency domain unit 4 is 4, and the interval between frequency domain unit 4 and frequency domain unit 6 is 2, that is, the distribution characteristics of the frequency domain units that meet the first characteristic are unequally spaced. In summary, the distribution characteristics of the frequency domain units that meet the first characteristic shown in part (1) of Figure 5 are discontinuous and unequally spaced.

[0124] Exemplarily, the distribution characteristics of the frequency domain units are discontinuous and equally spaced. Discontinuous means that any two frequency domain units that meet the first characteristic are not adjacent; equally spaced means that the interval between the i-th frequency domain unit that meets the first characteristic and the i+1-th frequency domain unit that meets the first characteristic is a fixed value, and i is a positive integer. As shown in part (2) of Figure 5, frequency domain unit 0, frequency domain unit 2, frequency domain unit 4, frequency domain unit 6, and frequency domain unit 8 are not adjacent, that is, the distribution characteristics of the frequency domain units that meet the first characteristic are discontinuous. The interval between frequency domain unit 0 and frequency domain unit 2, the interval between frequency domain unit 2 and frequency domain unit 4, the interval between frequency domain unit 4 and frequency domain unit 6, and the interval between frequency domain unit 6 and frequency domain unit 8 are all 2, that is, the distribution characteristics of the frequency domain units that meet the first characteristic are equally spaced. In summary, the distribution characteristics of the frequency domain units that meet the first characteristic shown in part (2) of Figure 5 are discontinuous and equally spaced.

[0125] Exemplarily, the distribution characteristic of the frequency domain unit is discontinuous. Discontinuous means that any two frequency domain units that meet the first characteristic are not adjacent. Frequency domain units with discontinuous distribution characteristics are shown in parts (1) and (2) of Figure 5.

[0126] In some embodiments, a frequency domain unit group can be used to represent one or more frequency domain units. For example, when the distribution characteristics of the frequency domain units are continuous and equally spaced, the frequency domain unit group includes multiple frequency domain units. When the distribution characteristics of the frequency domain units are continuous and unequally spaced, the frequency domain unit group includes one or more frequency domain units. When the distribution characteristics of the frequency domain units are continuous, the frequency domain unit group includes one frequency domain unit. When the distribution characteristics of the frequency domain units include non-continuous, the frequency domain unit group includes one frequency domain unit. The frequency domain unit group includes: one frequency domain unit or at least two continuous frequency domain units. The interval between the frequency domain unit groups can be the interval between the first frequency domain units of adjacent frequency domain unit groups or the interval between the last frequency domain unit of the previous frequency domain unit group and the first frequency domain unit of the next frequency domain unit group, that is, the interval between the i-th frequency domain unit group and the i+1-th frequency domain unit group is the interval between the first frequency domain unit in the i-th frequency domain unit group and the first frequency domain unit in the i+1-th frequency domain unit group, or the interval between the last frequency domain unit in the i-th frequency domain unit group and the first frequency domain unit in the i+1-th frequency domain unit group.

[0127] Exemplarily, the distribution characteristics of the frequency domain units are continuous and non-equally spaced. Continuous means that there are at least two adjacent frequency domain units among the frequency domain units that meet the first characteristic; non-equally spaced means that the i-th frequency domain unit group that meets the first characteristic and the i+1-th frequency domain unit group that meets the first characteristic are not fixed values, and i is a positive integer. As shown in part (3) of Figure 5, frequency domain unit 0 is adjacent to frequency domain unit 1, forming frequency domain unit group a1; frequency domain unit 4 forms frequency domain unit group a2; frequency domain unit 6, frequency domain unit 7 and frequency domain unit 8 are adjacent to each other, forming frequency domain unit group a3; since there are at least two adjacent frequency domain units, the distribution characteristics of the frequency domain units that meet the first characteristic are continuous; when the interval between the frequency domain unit groups is the interval between the first frequency domain units of the adjacent frequency domain unit groups, the interval between the frequency domain unit group a1 and the frequency domain unit group a2 is 4, and the frequency domain units The interval between group a2 and frequency domain unit group a3 is 2, that is, the intervals are not equal, and the distribution characteristics of the frequency domain units that meet the first characteristic are non-equal intervals; when the interval between frequency domain unit groups is the interval between the last frequency domain unit of the adjacent previous frequency domain unit group and the first frequency domain unit of the next frequency domain unit group, the interval between frequency domain unit group a1 and frequency domain unit group a2 is 3, and the interval between frequency domain unit group a2 and frequency domain unit group a3 is 2, that is, the intervals are not equal, and the distribution characteristics of the frequency domain unit groups that meet the first characteristic are non-equal intervals. In summary, the distribution characteristics of the frequency domain units that meet the first characteristic shown in part (3) of Figure 5 are continuous and non-equally spaced.

[0128] Exemplarily, the distribution characteristics of the frequency domain units are continuous and equally spaced. Continuous means that there are at least two adjacent frequency domain units among the frequency domain units that meet the first characteristic; equally spaced means that the i-th frequency domain unit group that meets the first characteristic and the i+1-th frequency domain unit group that meets the first characteristic are fixed values, where i is a positive integer. As shown in part (4) of Figure 5, frequency domain unit 0 and frequency domain unit 1 are adjacent, forming frequency domain unit group a1; frequency domain unit 3 and frequency domain unit 4 are adjacent, forming frequency domain unit group a2; frequency domain unit 6 and frequency domain unit 7 are adjacent, forming frequency domain unit group a3; since there are at least two adjacent frequency domain units, the distribution characteristics of frequency domain units that meet the first feature are continuous; when the interval between frequency domain unit groups is the interval between the first frequency domain units of adjacent frequency domain unit groups, the interval between frequency domain unit group a1 and frequency domain unit group a2, and the interval between frequency domain unit group a2 and frequency domain unit group a3 are both 3, that is, the distribution characteristics of frequency domain units that meet the first feature are equally spaced; when the interval between frequency domain unit groups is the interval between the last frequency domain unit of the previous frequency domain unit group and the first frequency domain unit of the next frequency domain unit group, the interval between frequency domain unit group a1 and frequency domain unit group a2, and the interval between frequency domain unit group a2 and frequency domain unit group a3 are both 2, that is, the distribution characteristics of frequency domain units that meet the first feature are equally spaced. In summary, the distribution characteristics of the frequency domain units that meet the first characteristic shown in part (4) of FIG5 are continuous and equally spaced.

[0129] As shown in part (5) of Figure 5, frequency domain unit 0 is adjacent to frequency domain unit 1, forming frequency domain unit group a1; frequency domain unit 3, frequency domain unit 4 and frequency domain unit 5 are adjacent to each other, forming frequency domain unit group a2; frequency domain unit 7 is adjacent to frequency domain unit 8, forming frequency domain unit group a3; since there are at least two adjacent frequency domain units, the distribution characteristics of frequency domain units that meet the first characteristic are continuous. When the interval between frequency domain unit groups is the interval between the first frequency domain units of adjacent frequency domain unit groups, the interval between frequency domain unit group a1 and frequency domain unit group a2 is 3, and the interval between frequency domain unit group a2 and frequency domain unit group a3 is 4, that is, the intervals are not equal, and the distribution characteristics of frequency domain units that meet the first characteristic are non-equal intervals; in summary, the distribution characteristics of frequency domain units that meet the first characteristic shown in part (5) of Figure 5 are continuous and non-equal intervals. When the interval between the frequency domain unit groups is the interval between the last frequency domain unit of the adjacent previous frequency domain unit group and the first frequency domain unit of the next frequency domain unit group, the interval between the frequency domain unit group a1 and the frequency domain unit group a2, and the interval between the frequency domain unit group a2 and the frequency domain unit group a3 are both 2, that is, the distribution characteristics of the frequency domain units that meet the first feature are equally spaced. In summary, the distribution characteristics of the frequency domain units that meet the first feature shown in part (5) of Figure 5 are continuous and equally spaced.

[0130] Exemplarily, the distribution characteristic of the frequency domain unit is continuous. Continuity means that there are at least two adjacent frequency domain units in the frequency domain unit that meets the first characteristic. As shown in part (6) of Figure 5, the frequency domain units that meet the first characteristic are frequency domain unit 0 to frequency domain unit 7, where frequency domain unit 0 is adjacent to frequency domain unit 1, frequency domain unit 1 is adjacent to frequency domain unit 2, ..., frequency domain unit 6 is adjacent to frequency domain unit 7, that is, the characteristic of the frequency domain units that meet the first characteristic is continuous.

There are 120 frequency domain units, frequency domain unit 0 to frequency domain unit 119. The distribution characteristics of these 120 frequency domain units are continuous and equally spaced. Each frequency domain unit group includes two consecutive frequency domain units, and the interval between the frequency domain unit groups is the interval between the first frequency domain units of adjacent frequency domain unit groups, that is, the interval between the frequency domain unit groups is 21. The frequency domain units that meet the first characteristic are {2, 3, 23, 24, 44, 45, 65, 66, 86, 87, 107, 108}.

[0149] The frequency domain unit range is represented using a bitmap, whereby frequency domain units that meet the first characteristic are represented as 1 and frequency domain units that do not meet the first characteristic are represented as 0; alternatively, frequency domain units that meet the first characteristic are represented as 0 and frequency domain units that do not meet the first characteristic are represented as 1.

The number of occupied frequency domain units is the number of frequency domain units that meet the first characteristic starting from the starting frequency domain unit group. The frequency domain unit range shown in FIG6 can be described as {starting frequency domain unit group: 2, 3; number of occupied frequency domain units: 12}.

This method is usually used to describe continuous frequency domain units. The frequency domain unit range shown in part (6) of Figure 5 can be described as {starting frequency domain unit group: 0; ending frequency domain unit group: 7}.

[0154] In some embodiments, the frequency domain unit pattern is used to indicate the frequency domain units that meet the first feature among a plurality of consecutive frequency domain units. The representation of the frequency domain unit pattern is similar to the frequency domain unit range.

[0155] In some embodiments, when the first information and / or the second information are used to indicate the frequency domain unit that meets the first characteristic, the following indication methods may be used. It should be noted that the embodiments of the present application only list some indication methods, but the protection scope of the embodiments of the present application is not limited thereto.

[0156] Method 1: Use frequency domain unit index.

[0157] When the number of frequency domain units meeting the first characteristic is less than the frequency domain unit threshold, the frequency domain unit index is directly used to indicate the frequency domain units meeting the first characteristic. The frequency domain unit threshold is configured by the first node or agreed upon by the communication protocol.

[0158] As shown in Figure 7, there are 120 subcarriers, from subcarrier 0 to subcarrier 119. Every 12 subcarriers form an RB, RB0 to RB9. The subcarriers that meet the first characteristic are subcarrier 24 to subcarrier 47. The frequency domain unit that meets the first characteristic is represented by a frequency domain unit index, which can be represented as subcarriers {24, 25, ..., 46, 47}.

[0159] Method 2: Use frequency domain unit set index.

[0160] When there are at least two frequency domain units that meet the first feature, the at least two frequency domain units that meet the first feature can be regarded as a frequency domain unit set. The frequency domain units that meet the first feature are represented by a frequency domain unit set index.

[0161] In some embodiments, the number of frequency domain units included in the frequency domain unit set is configured by the first node or agreed upon by the communication protocol. For example, a frequency domain unit set is an RB, a frequency domain unit is a subcarrier, and an RB includes 12 subcarriers.

[0162] As shown in Figure 7, there are 120 subcarriers, from subcarrier 0 to subcarrier 119. Every 12 subcarriers form an RB, RB0 to RB9. The subcarriers that meet the first characteristic are subcarrier 24 to subcarrier 47. The frequency domain unit that meets the first characteristic is represented by a frequency domain unit set index, that is, the RB index used to represent the subcarrier that meets the first characteristic can be expressed as {2, 3}.

[0163] In some embodiments, there are 6 types of frequency domain unit sets, each of which includes 10 frequency domain units. The distribution of frequency domain units in the 6 frequency domain unit sets is shown in parts (1) to (6) of Figure 5. The frequency domain unit set index is used to indicate the distribution of frequency domain units in the frequency domain unit set corresponding to the index. The 6 frequency domain unit sets can be represented by 6 bits or 3 bits. The frequency domain unit set corresponding to part (1) in Figure 5 is recorded as frequency domain unit set 1, the frequency domain unit set corresponding to part (2) in Figure 5 is recorded as frequency domain unit set 2; the frequency domain unit set corresponding to part (3) in Figure 5 is recorded as frequency domain unit set 3; the frequency domain unit set corresponding to part (4) in Figure 5 is recorded as frequency domain unit set 4; the frequency domain unit set corresponding to part (5) in Figure 5 is recorded as frequency domain unit set 5; and the frequency domain unit set corresponding to part (6) in Figure 5 is recorded as frequency domain unit set 6. If 3 bits are used to represent the frequency domain unit set index, the correspondence between the frequency domain unit set index and the frequency domain unit set is shown in Table 1 below.

[0164] Table 1. Correspondence between frequency domain unit set index and frequency domain unit set

[0165] That is, the frequency domain unit set index can be used to indicate the position of the frequency domain unit set, and can also be used to indicate the type of the frequency domain unit set.

[0166] Method 3: Use frequency domain unit index and frequency domain unit set index.

[0167] If not all frequency domain units in the frequency domain unit set meet the first characteristic, a frequency domain unit index and a frequency domain unit set index may be used for representation.

[0168] As shown in Figure 8, there are 120 subcarriers, subcarrier 0 to subcarrier 119. Every 12 subcarriers form an RB, RB0 to RB9. The subcarriers that meet the first feature are subcarrier 27 to subcarrier 30 and {subcarrier 37, subcarrier 39, subcarrier 41, subcarrier 43, subcarrier 45, subcarrier 47}. The frequency domain unit index and frequency domain unit set index are used to represent the frequency domain unit that meets the first feature, which can be represented as the frequency domain unit set index {2, 3} and the frequency domain unit index 1 {27, 28, 29, 30} and the frequency domain unit index 2 {37, 39, 41, 43, 45, 47}.

[0169] In some embodiments, the plurality of frequency domain unit sets are M frequency domain unit sets. Then the frequency domain unit set index is represented by M bits; or the frequency domain unit set index is represented by bits to represent, Each frequency domain unit set includes N frequency domain units. The frequency domain units that meet the first characteristic included in each frequency domain unit set can be indicated by a frequency domain unit index. The frequency domain unit index is represented by N bits, or the frequency domain unit index is represented by bits to represent, Indicates rounding up.

[0170] For example, the frequency domain unit set index is adopted below The frequency domain unit index is represented by bits, and the frequency domain unit index is represented by N bits for illustration. As shown in Figure 8, there are 10 frequency domain unit sets (RBs), each of which includes 12 frequency domain units (subcarriers). The frequency domain unit index in the frequency domain unit set can be represented by a bitmap, that is, the i-th bit represents the i-th frequency domain unit, the value of the i-th bit is 0, indicating that the i-th frequency domain unit does not meet the first feature, and the value of the i-th bit is 1, indicating that the i-th frequency domain unit meets the first feature. The frequency domain unit set index needs The frequency domain unit index requires 12 bits. The bit representation of the frequency domain unit index and the frequency domain unit set index is shown in Table 2 below.

[0171] Table 2. Bit representation of frequency domain unit index and frequency domain unit set index

[0172] Method 4: Use frequency domain unit range.

[0173] The frequency domain unit range is represented by a bitmap; or, the frequency domain unit range includes: a starting frequency domain unit group and the number of occupied frequency domain units; or, the frequency domain unit range includes: a starting frequency domain unit group and an ending frequency domain unit group; or, the frequency domain unit range includes: a starting frequency domain unit group, the number of occupied frequency domain units, and a frequency domain unit interval; or, the frequency domain unit range includes: a starting frequency domain unit group, the number of occupied frequency domain units, and a frequency domain unit density. The method of using the frequency domain unit range to represent the frequency domain units that meet the first characteristic is shown in the description corresponding to Figure 6 above and will not be repeated here.

[0174] Method 5: Use frequency domain unit pattern.

[0175] In some embodiments, the frequency domain unit pattern is used to indicate frequency domain units that meet the first characteristic in a plurality of consecutive frequency domain units.

[0176] As shown in Figure 6, there are 120 frequency domain units, from frequency domain unit 0 to frequency domain unit 119. The distribution characteristics of these 120 frequency domain units are continuous and equally spaced. Each frequency domain unit group includes two consecutive frequency domain units, and the interval between frequency domain unit groups is the interval between the first frequency domain units of adjacent frequency domain unit groups, that is, the interval between frequency domain unit groups is 21. The frequency domain units that meet the first characteristic are {2, 3, 23, 24, 44, 45, 65, 66, 86, 87, 107, 108}.

[0177] The frequency domain unit pattern is represented using a bitmap, whereby frequency domain units that meet the first characteristic are represented as 1 and frequency domain units that do not meet the first characteristic are represented as 0; alternatively, frequency domain units that meet the first characteristic are represented as 0 and frequency domain units that do not meet the first characteristic are represented as 1. The following example uses frequency domain units that meet the first characteristic as 1 and frequency domain units that do not meet the first characteristic as 0. The frequency domain unit pattern shown in Figure 6 can be described as {0011…11…11…0}.

[0178] The frequency domain unit pattern includes: a starting frequency domain unit group and a number of occupied frequency domain units. The number of occupied frequency domain units is the number of frequency domain units that meet the first characteristic starting from the starting frequency domain unit group. The frequency domain unit pattern shown in FIG6 can be described as {starting frequency domain unit group: 2, 3; number of occupied frequency domain units: 12}. The number of occupied frequency domain units is the total number of frequency domain units from the starting frequency domain unit group to the ending frequency domain unit group. The frequency domain unit pattern shown in part (6) of FIG5 can be described as {starting frequency domain unit group: 0; number of occupied frequency domain units: 8}.

[0179] The frequency domain unit pattern includes: a starting frequency domain unit group and an ending frequency domain unit group. This method is usually used to describe continuous frequency domain units.

[0180] The frequency domain unit pattern includes: a starting frequency domain unit group, a number of occupied frequency domain units, and a frequency domain unit interval. The number of occupied frequency domain units is the number of frequency domain units that meet the first characteristic starting from the starting frequency domain unit group. The frequency domain unit pattern shown in Figure 6 can be described as {starting frequency domain unit group: 2, 3; number of occupied frequency domain units: 12; frequency domain unit interval: 21}. The number of occupied frequency domain units is the total number of frequency domain units from the starting frequency domain unit group to the ending frequency domain unit group. The frequency domain unit pattern shown in Figure 6 can be described as {starting frequency domain unit group: 2, 3; number of occupied frequency domain units: 106; frequency domain unit interval: 21}.

[0181] The frequency domain unit pattern includes: a starting frequency domain unit group, a number of occupied frequency domain units, and a frequency domain unit density. The number of occupied frequency domain units is the number of frequency domain units that meet the first characteristic starting from the starting frequency domain unit group. If the first frequency domain range is frequency domain unit 0 to frequency domain unit 119, the frequency domain unit pattern shown in Figure 6 can be described as {starting frequency domain unit group: 2, 3; number of occupied frequency domain units: 12; frequency domain unit interval: 12}. The number of occupied frequency domain units is the total number of frequency domain units from the starting frequency domain unit group to the ending frequency domain unit group. If the first frequency domain range is frequency domain unit 0 to frequency domain unit 119, the frequency domain unit pattern shown in Figure 6 can be described as {starting frequency domain unit group: 2, 3; number of occupied frequency domain units: 106; frequency domain unit interval: 12}.

[0182] In some embodiments, a frequency domain unit pattern is used, including: using an RB frequency domain pattern and a subcarrier pattern within the RB. A frequency domain unit that meets the first feature can be represented by using an RB frequency domain pattern and a subcarrier pattern within the RB. In this case, the RBs that meet the first feature in the RB frequency domain pattern correspond to the subcarrier pattern within the same RB, that is, the subcarrier distribution characteristics that meet the first feature included in each RB that meets the first feature are the same; or a frequency domain unit that meets the first feature can be represented by using an RB frequency domain pattern and subcarrier patterns within multiple RBs. In this case, the representation methods used for the subcarrier patterns within multiple RBs can be the same or different, such as subcarrier pattern 1 within the RB is represented by a bitmap, subcarrier pattern 2 within the RB includes a starting frequency domain unit group and the number of occupied frequency domain units, and subcarrier pattern 3 within the RB includes: a starting frequency domain unit group, the number of occupied frequency domain units, and the frequency domain unit interval, etc.

[0183] Method 6: Use frequency domain unit range and frequency domain unit pattern.

[0184] In some embodiments, at least one of the frequency domain unit pattern and the frequency domain unit range may constitute a perception signal frequency domain pattern.

[0185] For example, the frequency domain unit is RB, and the frequency domain pattern of the perception signal includes the RB frequency domain range and the subcarrier pattern within the RB. That is, the above-mentioned fourth and fifth methods can be combined for representation.

[0186] Specific combinations may include: the RB frequency domain range is represented by a bitmap, and the subcarrier pattern within the RB is also represented by a bitmap; or, the RB frequency domain range includes: the starting RB group and the number of RB occupied, and the subcarrier pattern within the RB includes: the starting subcarrier group and the number of subcarrier occupied; or, the RB frequency domain range includes: the starting RB group and the ending RB group, and the subcarrier pattern within the RB includes: the starting subcarrier group and the ending subcarrier group; or, the RB frequency domain range includes: the starting RB group, the number of RB occupied and the RB interval, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of subcarrier occupied or, the RB frequency domain range includes: the starting RB group, the number of RB occupied and the RB density, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of subcarrier occupied and the subcarrier density; or, the RB frequency domain range is represented by a bitmap, and the subcarrier pattern within the RB includes: the starting subcarrier group and the number of subcarrier occupied; or, the RB frequency domain range is represented by a bitmap, and the subcarrier pattern within the RB includes: the starting subcarrier group and the ending subcarrier group; or, the RB frequency domain range is represented by a bitmap, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of subcarrier occupied and the ending subcarrier group. Carrier spacing; or, the RB frequency domain range is represented by a bitmap, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of subcarrier occupations, and the subcarrier density; or, the RB frequency domain range includes: the starting RB group and the number of RB occupations, and the subcarrier pattern within the RB includes: the starting subcarrier group and the ending subcarrier group; or, the RB frequency domain range includes: the starting RB group and the number of RB occupations, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of subcarrier occupations, and the subcarrier spacing; or, the RB frequency domain range includes: the starting RB group and the number of RB occupations, and the subcarrier pattern within the RB includes : starting subcarrier group, number of occupied subcarriers and subcarrier density; or, the RB frequency domain range includes: the starting RB group and the ending RB group, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of occupied subcarriers and the subcarrier spacing; or, the RB frequency domain range includes: the starting RB group and the ending RB group, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of occupied subcarriers and the subcarrier density; or, the RB frequency domain range includes: the starting RB group, the number of occupied RBs and the RB spacing, and the subcarrier pattern within the RB includes: the starting subcarrier group, the number of occupied subcarriers and the subcarrier density.

[0187] It should be noted that a frequency domain unit range and a frequency domain unit pattern can be used to represent a frequency domain unit that meets the first feature, or a frequency domain unit range and multiple frequency domain unit patterns can be used to represent a frequency domain unit that meets the first feature. In this case, the representation methods used by multiple frequency domain unit patterns can be the same or different. For example, frequency domain unit pattern 1 is represented by a bitmap, frequency domain unit pattern 2 includes a starting frequency domain unit group and the number of occupied frequency domain units, and frequency domain unit pattern 3 includes: a starting frequency domain unit group, the number of occupied frequency domain units, and the frequency domain unit interval, etc.

[0188] As shown in Figure 8, there are 120 subcarriers, from subcarrier 0 to subcarrier 119. Every 12 subcarriers form an RB, RB0 to RB9. The subcarriers that meet the first characteristic are subcarriers 27 to 30 and {subcarrier 37, subcarrier 39, subcarrier 41, subcarrier 43, subcarrier 45, subcarrier 47}. The RB frequency domain range is represented by a bitmap, and the subcarrier pattern within the RB is also represented by a bitmap. The RB frequency domain range can be represented as 00 1100 0000, subcarrier pattern 1 within the RB can be represented as 0001 1110 0000, and subcarrier pattern 2 within the RB can be represented as 0101 0101 0101.

[0189] Method 7: Use frequency domain unit pattern index.

[0190] In the case of including a plurality of frequency domain unit patterns, a frequency domain unit pattern index may be used to indicate one frequency domain unit pattern among the plurality of frequency domain unit patterns.

[0191] In some embodiments, the multiple frequency domain unit patterns are sent by the second node to the first node; or, the multiple frequency domain unit patterns are configured by the first node; or, the multiple frequency domain unit patterns are agreed upon in a communication protocol.

[0192] In some embodiments, the plurality of frequency domain unit patterns are M frequency domain unit patterns. Then the frequency domain unit pattern index is represented by M bits; or the frequency domain unit pattern index is represented by bits to represent, Indicates rounding up.

[0193] For example, multiple frequency domain unit patterns include {frequency domain unit pattern 1: full bandwidth continuous frequency domain units; frequency domain unit pattern 2: starting frequency domain unit group = 2, 3, number of frequency domain unit occupancy = 106, frequency domain unit interval = 21; frequency domain unit pattern 3: starting frequency domain unit group = 1, ending frequency domain unit group = 5}. bits are used to represent the frequency domain unit pattern index. The corresponding relationship between the frequency domain unit pattern index and the frequency domain unit pattern is shown in Table 3 below.

[0194] Table 3. Correspondence between frequency domain unit pattern index and frequency domain unit pattern

[0195] Method 8: Using frequency domain unit pattern and frequency domain unit pattern index.

[0196] In some embodiments, the second node sends a plurality of frequency domain unit patterns and a frequency domain unit pattern index corresponding to a frequency domain unit that satisfies a first characteristic to the first node. The frequency domain unit pattern indicated by the frequency domain unit pattern index corresponding to the frequency domain unit that satisfies the first characteristic is all or part of the plurality of frequency domain unit patterns.

[0197] In some embodiments, the multiple frequency domain unit patterns corresponding to the frequency domain unit pattern index are the frequency domain unit patterns shown in the above-mentioned method five.

[0198] For example, multiple frequency domain unit patterns include {frequency domain unit pattern 1: full bandwidth continuous frequency domain units; frequency domain unit pattern 2: starting frequency domain unit group = 2, 3, number of frequency domain unit occupancy = 106, frequency domain unit interval = 21; frequency domain unit pattern 3: starting frequency domain unit group = 1, ending frequency domain unit group = 5}. bits are used to represent the frequency domain unit pattern index. The corresponding relationship between the frequency domain unit pattern index and the frequency domain unit pattern is shown in Table 3.

[0199] Method nine: using the frequency domain unit range, frequency domain unit pattern, and frequency domain unit pattern index.

[0200] In some embodiments, at least one of the frequency domain unit pattern and the frequency domain unit range may constitute a perception signal frequency domain pattern.

[0201] For example, the frequency domain unit is an RB, and the perception signal frequency domain pattern includes the RB frequency domain range and the subcarrier pattern within the RB. The frequency domain unit pattern index is used to indicate a perception signal frequency domain pattern among multiple perception signal frequency domain patterns.

[0202] In some embodiments, the multiple frequency domain unit patterns corresponding to the frequency domain unit pattern index are the perception signal frequency domain patterns shown in the sixth embodiment. The perception signal frequency domain pattern includes a frequency domain unit pattern and a frequency domain unit range. The multiple frequency domain unit patterns are sent by the second node to the first node; or, the multiple frequency domain unit patterns are configured by the first node; or, the multiple frequency domain unit patterns are agreed upon in a communication protocol.

[0203] For example, multiple perception signal frequency domain patterns include {perception signal frequency domain pattern 1: frequency domain unit range 1 {starting frequency domain unit group = 2, 3, number of frequency domain unit occupancy = 106, frequency domain unit spacing = 21}, frequency domain unit pattern 1 {starting frequency domain unit group = 3, number of frequency domain unit occupancy = 4, frequency domain unit density = 4}, frequency domain unit pattern 2 {starting frequency domain unit group = 1, frequency domain unit spacing = 2}; perception signal frequency domain pattern 2: frequency domain unit range 2 {starting frequency domain unit group = 0, number of frequency domain unit occupancy = 120}; perception signal frequency domain pattern 3: frequency domain unit range 3 {starting frequency domain unit group = 1, ending frequency domain unit group = 5}, frequency domain unit pattern 3 {starting frequency domain unit group = 0, number of frequency domain unit occupancy = 12, frequency domain unit density = 12}}. A 3-bit frequency domain unit pattern index can be used for representation. The first bit corresponds to perceptual signal frequency domain pattern 1. A value of 0 indicates that the frequency domain unit satisfying the first characteristic is not represented by perceptual signal frequency domain pattern 1, and a value of 1 indicates that the frequency domain unit satisfying the first characteristic is represented by perceptual signal frequency domain pattern 1. The second bit corresponds to perceptual signal frequency domain pattern 2. A value of 0 indicates that the frequency domain unit satisfying the first characteristic is not represented by perceptual signal frequency domain pattern 2, and a value of 1 indicates that the frequency domain unit satisfying the first characteristic is represented by perceptual signal frequency domain pattern 2. The third bit corresponds to perceptual signal frequency domain pattern 3. A value of 0 indicates that the frequency domain unit satisfying the first characteristic is not represented by perceptual signal frequency domain pattern 3, and a value of 1 indicates that the frequency domain unit satisfying the first characteristic is represented by perceptual signal frequency domain pattern 3. If the frequency domain unit pattern index is 001, it indicates that the frequency domain unit satisfying the first characteristic is represented by perceptual signal frequency domain pattern 3.

[0204] (4) Indication form of time domain unit

[0205] In some embodiments, the first information further includes a time domain unit. The second information further includes a time domain unit. The time domain unit is a time domain unit that satisfies the first feature, and the time domain unit may also be a time domain unit corresponding to a frequency domain unit that satisfies the first feature. The time domain unit indicated in the first information and the time domain unit indicated in the second information are the same, intersecting, or different. However, the indication form of the time domain unit in the first information and the second information may be at least one of the following, that is, the first information and the second information include at least one of the following:

[0206] Time domain unit index;

[0207] Time domain unit set index;

[0208] Time domain unit range;

[0209] Time domain unit pattern;

[0210] Time domain unit pattern index.

[0211] Among them, the time domain unit index is used to indicate the time domain unit; the time domain unit set index is used to indicate the time domain unit set, and the time domain unit set includes at least two time domain units; the time domain unit range is used to indicate the time domain range corresponding to the time domain unit; the time domain unit pattern is used to indicate the time domain unit in multiple consecutive time domain units; the time domain unit pattern index is used to indicate a time domain unit pattern in multiple time domain unit patterns.

[0212] In some embodiments, a time domain unit index is used to indicate a time domain unit that satisfies a first characteristic; a time domain unit set index is used to indicate a time domain unit set, the time domain unit set includes at least two time domain units, and at least one time domain unit of the at least two time domain units satisfies the first characteristic; a time domain unit range is used to indicate a time domain range, and at least one time domain unit within the time domain range satisfies the first characteristic; a time domain unit pattern is used to indicate a time domain unit that satisfies the first characteristic among a plurality of consecutive time domain units; a time domain unit pattern index is used to indicate a time domain unit pattern among a plurality of time domain unit patterns, or a time domain unit pattern index is used to indicate a time domain unit pattern that satisfies the first characteristic. By way of example and not limitation, a time domain unit is at least one of a frame, a subframe, a slot, or a symbol. Optionally, the time length of a frame is defined as 10ms; a frame includes 10 subframes, and the time length of a subframe is 1ms; a subframe includes i time slots, where i is a positive integer and the value of i is related to the subcarrier spacing. The larger the subcarrier spacing, the shorter the actual time length of a time slot; a time slot includes 14 symbols, which can be OFDM symbols. It should be noted that the time length of a frame can also be defined as other time lengths, such as 15ms, 20ms, etc., and this embodiment of the present application is not limited to this.

[0213] In some embodiments, the time domain unit set corresponding to the time domain unit set index includes: at least two time domain units. The at least two time domain units are continuous or discontinuous in the time domain.

[0214] In some embodiments, the expression form of the time domain unit set index is similar to the expression form of the frequency domain unit set index, the expression form of the time domain unit range is similar to the expression form of the frequency domain unit range, the expression form of the time domain unit pattern is similar to the expression form of the frequency domain unit pattern, and the expression form of the time domain unit pattern index is similar to the expression form of the frequency domain unit pattern index, which will not be repeated here.

[0215] In some embodiments, the first information or the second information can be used to indicate the frequency domain unit that meets the first characteristic and the time domain unit corresponding to the frequency domain unit. That is, the above-mentioned "indication form of the frequency domain unit" and "indication form of the time domain unit" can be implemented in combination.

[0216] For example, a perception signal pattern is used to indicate the time domain unit and the frequency domain unit. The perception signal pattern includes at least one of the frequency domain resource configuration and the time domain resource configuration. The frequency domain resource configuration can refer to the above-mentioned methods one to nine. The time domain resource configuration can refer to the indication form of the time domain unit. For example, the perception signal pattern is {frequency domain resource configuration: frequency domain unit range 1{starting frequency domain unit group = 0, number of frequency domain unit occupancy = 120}; time domain voluntary configuration: time domain unit range 1{starting time domain unit group = 9, ending time domain unit group = 29}}, or, {frequency domain resource configuration: frequency domain unit range 1{starting frequency domain unit group = 2, 3, number of frequency domain unit occupancy = 106, frequency domain unit interval = 21}; time domain resource configuration: time domain unit range 1{starting time domain unit group = 0, ending time domain unit group = 13}}, etc.

[0217] Exemplarily, the plurality of perception signal patterns include perception signal pattern 1, perception signal pattern 2, perception signal pattern 3, and perception signal pattern 4. Perception signal pattern 1 includes frequency domain resource configuration 1, perception signal pattern 2 includes frequency domain resource configuration 2 and time domain resource configuration 1, perception signal pattern 3 includes frequency domain resource configuration 3, and perception signal configuration 4 includes time domain resource configuration 2. bits are used to represent the perception signal pattern index. The corresponding relationship between the perception signal pattern index and the perception signal is shown in Table 4.

[0218] Table 4. Correspondence between perception signal pattern index and perception signal

[0219] Next, the method for reporting perception information and the method for sending perception signal configuration shown in the embodiments of the present application are further explained.

[0220] In an optional embodiment based on FIG. 3 or FIG. 4 , FIG. 9 shows an overall flow chart of a method for reporting perception information and a method for sending a perception signal configuration provided by an exemplary embodiment of the present application. The method includes:

[0221] Step 410: The first node sends a first sensing signal configuration to the second node.

[0222] The frequency domain unit configured by the first perception signal configuration has a larger range, for example, the frequency domain unit configured by the first perception signal configuration is a continuous subcarrier of the full bandwidth.

[0223] In some embodiments, the second node receives the first sensing signal configuration sent by the first node.

[0224] Step 420: The second node sends the first information to the first node.

[0225] In some embodiments, the second node receives a perception signal on a frequency domain unit configured by the first perception signal configuration, analyzes a characteristic of the frequency domain unit based on the perception signal received on the frequency domain unit, selects a frequency domain unit that satisfies the first characteristic, and indicates the frequency domain unit that satisfies the first characteristic using the first information.

[0226] In some embodiments, the second node sends the first information to the first node at a fixed time; the fixed time is a time interval, such as sending the first information to the first node every 60 seconds, and the frequency domain units satisfying the first characteristic indicated by each transmission of the first information are the same or different; the fixed time is configured by the first node or agreed upon in a communication protocol. Alternatively, the second node sends the first information to the first node based on a sensing service, such as sending the first information to the first node before formally processing the sensing service.

[0227] In some embodiments, the first node receives first information sent by the second node.

[0228] Step 430: The first node sends a second sensing signal configuration to the second node.

[0229] The frequency domain units configured by the second perception signal configuration are a subset of the frequency domain units configured by the first perception signal configuration.

[0230] In some embodiments, the second node receives the second sensing signal configuration sent by the first node.

[0231] In some embodiments, the first node obtains a second perception signal configuration based on the first information sent by the second node, where the second perception signal configuration includes second information, where the second information is used to indicate a frequency domain unit, and the frequency domain unit indicated by the second information is a frequency domain unit that satisfies the first characteristic.

[0232] In some embodiments, the frequency domain unit indicated by the second information is the same as the frequency domain unit indicated by the first information; or, the frequency domain unit indicated by the second information is a subset of the frequency domain unit indicated by the first information; or, the frequency domain unit indicated by the first information is a subset of the frequency domain unit indicated by the second information; or, the frequency domain unit indicated by the first information and the frequency domain unit indicated by the second information have an intersection. That is, the first node configures the frequency domain unit indicated by the first information to the second node based on the first information; or, the first node selects some of the frequency domain units indicated by the first information to configure to the second node based on the perception requirement; or, the first node selects some of the frequency domain units indicated by the first information in addition to all the frequency domain units indicated by the first information, and configures these frequency domain units to the second node based on the perception requirement; or, the first node selects some of the frequency domain units in addition to some of the frequency domain units indicated by the first information, and configures these frequency domain units to the second node based on the perception requirement.

[0233] In summary, the method provided in the embodiment of the present application illustrates the entire process of configuring the perception signal. First, the first node configures a frequency domain unit with a larger range through the first perception signal configuration, and the second node selects a frequency domain unit that satisfies the first feature on the frequency domain unit configured by the first perception signal configuration, and uses the first information to indicate all the frequency domain units that meet the first feature. The first node will determine the frequency domain units used for perception between the first node and the second node based on the frequency domain units indicated by the first information, that is, all or part of the frequency domain units in the frequency domain units indicated by the first information, and use the second information to indicate these frequency domain units. Finally, the first node will use the second perception signal configuration to configure the second information to the second node to complete the entire perception signal configuration process. This enables the first node to send a perception signal on a frequency domain unit that meets the first feature, and the second node to receive a perception signal on a frequency domain unit that meets the first feature. Compared with sending and receiving within the full frequency domain range, it can greatly save the resource overhead of the first node and the second node, improve resource utilization; at the same time, it can also minimize the impact on the original communication system.

[0234] In addition to the above-mentioned perception signal configuration and first information, in the information reporting method for perception and the method for sending the perception signal configuration, the first node and the second node can also use other information to interact, so that the entire perception configuration process becomes more controllable for the first node and the second node.

[0235] In an optional embodiment based on FIG. 9 , as shown in FIG. 10 , the first node uses the perception reporting configuration to instruct the second node to report the first information, and the method further includes step 510 .

[0236] Step 510: The first node sends a first perception reporting configuration to the second node.

[0237] In some embodiments, the perception reporting configuration is associated with a perception signal configuration, and the perception reporting configuration is used to indicate perception information obtained by the second node based on the perception signal. That is, the first perception reporting configuration is associated with the first perception signal configuration.

[0238] In some embodiments, the perception reporting configuration includes a transmission resource reporting indication, where the transmission resource reporting indication is used to instruct the second node to report first information to the first node, where the first information is used to indicate a frequency domain unit and / or a time domain unit that meets the first characteristic. That is, after receiving the transmission resource reporting indication, the second node sends the first information to the first node.

[0239] In some embodiments, the first perception reporting configuration includes a transmission resource reporting indication, which is used to instruct the second node to select a frequency domain unit that meets the first characteristic for reporting based on the first perception signal configuration.

[0240] In some embodiments, the second node receives the first perception reporting configuration sent by the first node.

[0241] In summary, the method provided in the embodiments of the present application instructs a second node to report first information through a first perception reporting configuration. Upon receiving the transmission resource reporting instruction in the first perception reporting configuration, the second node sends the first information to the first node, where the first information is used to indicate at least a frequency domain unit that satisfies the first characteristic. The first node instructs the second node to report the first information, enabling the first node to flexibly control the entire perception configuration process.

[0242] In an optional embodiment based on FIG. 9 , as shown in FIG. 11 , the first node uses the perception reporting configuration to indicate the type of perception results that the second node needs to collect during the perception process. The method further includes step 520 .

[0243] Step 520: The first node sends a second perception reporting configuration to the second node.

[0244] In some embodiments, the second perception reporting configuration is associated with a second perception signal configuration.

[0245] In some embodiments, the perception reporting configuration includes a perception result configuration, which is used to indicate the type of perception result to be collected by the second node, and the perception result includes at least one of the following information: channel information; perception parameters; instantaneous perception parameters; and perception parameter characteristics.

[0246] The channel information is used to indicate the information of the channel corresponding to the frequency domain unit. The channel information includes the channel amplitude and / or angle of each frequency domain unit. The channel information also includes at least one of the delay, channel amplitude, and angle of the time domain channel corresponding to the frequency domain unit. The perception parameter is used to indicate information related to the perception signal. The perception parameter includes at least one of speed, Doppler, distance, delay, and angle. Doppler is used to indicate the Doppler shift of the perception signal, that is, the difference between the transmit frequency and the receive frequency of the perception signal. The instantaneous perception parameter represents the perception parameter measured within the agreed time unit. The agreed time unit can be one or more subframes, one or more time slots, one or more symbols, etc. The perception parameter feature is used to indicate the measurement characteristics of the perception parameter, that is, how often the perception parameter is measured and how long the measurement time is. The perception parameter features include frequency, periodic components, etc.

[0247] In some embodiments, the second sensing reporting configuration includes a sensing result configuration, which is used to instruct the second node to collect sensing results related to the sensing result configuration on frequency domain units based on the second sensing signal configuration.

[0248] In some embodiments, the second node receives the perception reporting configuration sent by the first node.

[0249] In summary, the method provided in the embodiments of the present application instructs the second node to report perception results through a perception reporting configuration. The second node can configure selective measurements and reporting of perception results based on the perception results sent by the first node. This allows the first node to flexibly configure the required perception result types. Furthermore, by collecting perception result types based on the perception result configuration rather than directly collecting all perception result types, energy consumption of both the first and second nodes can be reduced.

[0250] In some embodiments, the first perception reporting configuration also includes a perception result configuration; or the second perception reporting configuration also includes a transmission resource reporting indication. That is, the perception reporting configuration includes the perception result configuration and / or the transmission resource reporting indication, and the first perception reporting configuration and the second perception reporting configuration are perception reporting configurations. This is not limited in the present embodiment.

[0251] In addition, description information may be used between the first node and the second node to indicate features of the frequency domain unit included in the first information / the second information.

[0252] In an optional embodiment based on FIG9 , as shown in FIG12 , the second node uses the first description information to describe the first feature to the first node. The method further includes step 530 .

[0253] Step 530: The second node sends first description information to the first node.

[0254] In some embodiments, the second node uses the first description information to indicate the frequency domain unit selection criteria of the second node to the first node. The content of the first description information is as shown in the following "(5) First Description Information / Second Description Information" and is not repeated here.

[0285] In an optional embodiment based on FIG9 , as shown in FIG14 , the second node collects the sensing results during the sensing process and reports them to the first node.

[0286] Step 550: The second node sends the perception result to the first node.

[0287] In some embodiments, the perception result is obtained based on frequency domain units that meet the first characteristic.

[0288] In some embodiments, the sensing result includes at least one of the following information: channel information; sensing parameters; instantaneous sensing parameters; and sensing parameter characteristics. Where the sensing result includes the instantaneous sensing parameters, the sensing result sent by the second node to the first node includes independent instantaneous sensing parameters measured over one or more time units.

[0290] In some embodiments, the first node receives the sensing result sent by the second node.

[0291] In summary, in the method provided in the embodiments of the present application, the second node transmits a perception result to the first node. This perception result is obtained by the second node based on the frequency domain unit indicated by the first information, or based on the frequency domain unit indicated by the second perception signal configuration. Based on this perception result, the first node can perform perception analysis, thereby completing the entire perception process. Simultaneously, the first node performs the perception analysis, which reduces the complexity of the second node, requiring the second node to simply receive the perception signal.

[0294] Next, several specific processes using the above-mentioned method for reporting information for perception and the method for sending perception signal configuration are shown.

[0295] 1. Subcarrier index or subcarrier set index.

[0296] The second node sends the first information to the first node. The first information can be called subcarrier information. The subcarrier information includes a subcarrier index or a subcarrier set index. For example, in the scenario of respiratory monitoring, breathing affects the amplitude of different subcarriers. Based on the amplitude change variance of the subcarrier, the subcarrier with the larger amplitude change variance is selected. The selected subcarrier is represented by the subcarrier index. As shown in Figure 15, the horizontal axis is the subcarrier index and the vertical axis is the amplitude change variance. The selected subcarrier index is 24-47.

[0297] In some embodiments, every 12 subcarriers may be represented as an RB, and an RB may be referred to as a subcarrier set or a subcarrier group. The subcarrier set index corresponding to FIG15 is {2, 3}.

[0298] 2. Perceptual signal frequency domain pattern or perceptual signal frequency domain pattern index.

[0299] In some embodiments, subcarriers with large amplitude variation variance exhibit periodicity. In this case, a perception signal frequency domain pattern can be used to indicate subcarriers with large amplitude variation variance. The perception signal frequency domain pattern includes an RB pattern and a subcarrier pattern within an RB. The specific representations are as described in Methods 4 to 9 in "(3) Frequency Domain Unit Indication Form" above and are not further described here.

[0300] 3. Perception signal pattern or perception signal pattern index.

[0301] In some embodiments, in addition to frequency domain units, the first information is also used to indicate time domain units. The perception signal pattern includes at least one of a frequency domain resource configuration and a time domain resource configuration. The specific representation is as described in "(3) Indication form of frequency domain units" and "(4) Indication form of time domain units" above and will not be repeated here.

[0302] FIG16 shows a block diagram of a device for reporting perceived information provided by an exemplary embodiment of the present application. The device can be implemented as a second node, or as a part of a second node, through software or hardware, or a combination of both. The device includes:

[0303] The first sending module 610 is used to send first information to the first node, where the first information is used to indicate a frequency domain unit that meets a first feature, and the first feature is a feature related to perception.

[0304] A frequency domain unit is the basic unit for dividing the frequency domain. For example, a frequency domain unit is an RB (Resource Block) or a subcarrier. The frequency domain units that meet the first characteristic are a portion of all frequency domain units in the full bandwidth, or a portion of all frequency domain units that carry perception signals.

[0305] In some embodiments, the frequency domain unit that meets the first characteristic is selected by the second node; or, the frequency domain unit that meets the first characteristic is selected by the perception receiving node; or, the frequency domain unit that meets the first characteristic is selected by the perception control node; or, the frequency domain unit that meets the first characteristic is selected by the perception management node.

[0306] The first feature is a feature related to perception. Alternatively, it can be said that the first feature is a feature that facilitates perception. Alternatively, it can be said that the first feature is a feature that is sensitive to perception, or that is sensitive to perceptual signals. The first feature is described in "(1) First Feature" below and will not be further described here.

[0307] In summary, the apparatus provided in the embodiment of the present application shows that the second node sends a frequency domain unit that meets the first feature to the first node. The second node is a sensing node that receives the sensing signal or a sensing management node responsible for management. The second node can select a frequency domain unit that meets the first feature based on the characteristics of the received sensing signal and report it to the first node, so that the first node can understand the characteristics of the frequency domain unit when sending the subsequent sensing signal and select an appropriate frequency domain unit to send the sensing signal, thereby avoiding the selection of an unsuitable frequency domain unit for sensing due to blind selection, resulting in poor sensing effect; or, the first node does not select and directly uses all frequency domain units for sensing, resulting in affecting other signals, such as communication signals or signals sent by other users. After the second node sends the first information to the first node, the first node can send the sensing signal based on the first information. The first information indicates the frequency domain unit that meets the first feature. Using the frequency domain unit indicated by the first information to send the sensing signal instead of using the frequency domain units of the entire frequency domain to send the sensing signal can improve resource utilization and save energy for the first and second nodes.

[0308] FIG17 shows a structural block diagram of a device for sending a perception signal configuration according to an exemplary embodiment of the present application. The device can be implemented as a first node, or as a part of a first node, through software or hardware, or a combination of both. The device includes:

[0309] The second sending module 710 is configured to send a second sensing signal configuration to the second node, where the second sensing signal configuration includes second information, and the second information is used to indicate a frequency domain unit.

[0310] In some embodiments, the second information is used to indicate a frequency domain unit that meets the first characteristic. In other words, the second information is used to indicate a frequency domain unit, and the frequency domain unit indicated by the second information is a frequency domain unit that meets the first characteristic.

[0311] A frequency domain unit is a basic unit for dividing the frequency domain. For example, a frequency domain unit is an RB or a subcarrier. The frequency domain unit indicated by the second information is a portion of the frequency domain units of the full bandwidth, or a portion of the frequency domain units of all frequency domain units that carry perception signals.

[0312] The first feature is a feature related to perception. Alternatively, it can be said that the first feature is a feature that facilitates perception. Alternatively, it can be said that the first feature is a feature that is sensitive to perception, or that is sensitive to perceptual signals. The first feature is described in "(1) First Feature" below and will not be further described here.

[0313] In summary, in the apparatus provided by the embodiment of the present application, the first node sends a second perception signal configuration to the second node, and the second perception signal configuration includes second information for indicating a frequency domain unit that meets the first characteristic. Informing the second node that it needs to detect the perception signal on the frequency domain unit indicated by the second information can eliminate the need for the second node to perform perception detection on all frequency domain units, thereby reducing the energy consumption of the second node and the complexity of information reception at the second node. The first node and the second node agree on the frequency domain unit for sending the perception signal through configuration, that is, agree on the frequency domain unit that participates in perception, which can reduce the complexity of the second node's reception as much as possible. The second node does not need to distinguish whether the signal on each frequency domain unit is a perception signal, and only needs to perceive on the frequency domain unit indicated by the second information.

[0314] Next, the apparatus for reporting perception information and the apparatus for sending perception signal configuration shown in the embodiments of the present application will be further described.

[0315] In an optional embodiment based on FIG. 16 or FIG. 17 , the apparatus for reporting perception information further includes a first receiving module 620 , and the apparatus for sending perception signal configuration further includes a second receiving module 720 .

[0316] The second sending module 710 is configured to send the first perception signal configuration to the second node.

[0317] The frequency domain unit configured by the first perception signal configuration has a larger range, for example, the frequency domain unit configured by the first perception signal configuration is a continuous subcarrier of the full bandwidth.

[0318] In some embodiments, the first receiving module 620 is configured to receive a first sensing signal configuration sent by a first node.

[0319] The first sending module 610 is configured for the second node to send first information to the first node.

[0320] In some embodiments, the second node receives a perception signal on a frequency domain unit configured by the first perception signal configuration, analyzes a characteristic of the frequency domain unit based on the perception signal received on the frequency domain unit, selects a frequency domain unit that satisfies the first characteristic, and indicates the frequency domain unit that satisfies the first characteristic using the first information.

[0321] In some embodiments, the second node sends the first information to the first node at a fixed time; the fixed time is a time interval, such as sending the first information to the first node every 60 seconds, and the frequency domain units satisfying the first characteristic indicated by each transmission of the first information are the same or different; the fixed time is configured by the first node or agreed upon in a communication protocol. Alternatively, the second node sends the first information to the first node based on a sensing service, such as sending the first information to the first node before formally processing the sensing service.

[0322] In some embodiments, the second receiving module 720 is configured to receive first information sent by a second node.

[0323] The second sending module 710 is configured to send a second sensing signal configuration to the second node.

[0324] In some embodiments, the first receiving module 620 is configured to receive a second sensing signal configuration sent by the first node.

[0325] In some embodiments, the first node obtains a second perception signal configuration based on the first information sent by the second node, where the second perception signal configuration includes second information, where the second information is used to indicate a frequency domain unit, and the frequency domain unit indicated by the second information is a frequency domain unit that satisfies the first characteristic.

[0326] In some embodiments, the frequency domain unit indicated by the second information is the same as the frequency domain unit indicated by the first information; or, the frequency domain unit indicated by the second information is a subset of the frequency domain unit indicated by the first information; or, the frequency domain unit indicated by the first information is a subset of the frequency domain unit indicated by the second information; or, the frequency domain unit indicated by the first information and the frequency domain unit indicated by the second information have an intersection. That is, the first node configures the frequency domain unit indicated by the first information to the second node based on the first information; or, the first node selects some of the frequency domain units indicated by the first information to configure to the second node based on the perception requirement; or, the first node selects some of the frequency domain units indicated by the first information in addition to all the frequency domain units indicated by the first information, and configures these frequency domain units to the second node based on the perception requirement; or, the first node selects some of the frequency domain units in addition to some of the frequency domain units indicated by the first information, and configures these frequency domain units to the second node based on the perception requirement.

[0327] In summary, the device provided in the embodiment of the present application shows the entire process of perceptual signal configuration. First, the first node configures a frequency domain unit with a larger range through the first perceptual signal configuration, and the second node selects a frequency domain unit that satisfies the first feature on the frequency domain unit configured by the first perceptual signal configuration, and uses the first information to indicate all frequency domain units that satisfy the first feature. The first node will determine the frequency domain units used for perception between the first node and the second node based on the frequency domain units indicated by the first information, that is, all or part of the frequency domain units in the frequency domain units indicated by the first information, and use the second information to indicate these frequency domain units. Finally, the first node will use the second perceptual signal configuration to configure the second information to the second node to complete the entire perceptual signal configuration process. This enables the first node to send a perceptual signal on a frequency domain unit that satisfies the first feature, and the second node to receive a perceptual signal on a frequency domain unit that satisfies the first feature. Compared with transmitting and receiving within the full frequency domain range, this can greatly save the resource overhead of the first node and the second node, improve resource utilization, and at the same time minimize the impact on the original communication system.

[0328] In an optional embodiment based on FIG. 16 or FIG. 17 , the apparatus for reporting perception information further includes a first receiving module 620 , and the apparatus for sending perception signal configuration further includes a second receiving module 720 .

[0329] The second sending module 710 is used to send the first perception reporting configuration to the second node.

[0330] In some embodiments, the perception reporting configuration is associated with a perception signal configuration, and the perception reporting configuration is used to indicate perception information obtained by the second node based on the perception signal. That is, the first perception reporting configuration is associated with the first perception signal configuration. The specific information of the first perception reporting configuration is as described in step 510 above and will not be further described here.

[0331] In some embodiments, the first receiving module 620 is configured to receive a first perception reporting configuration sent by a first node.

[0332] In summary, the apparatus provided in the embodiments of the present application instructs a second node to report first information through a first perception reporting configuration. Upon receiving the transmission resource reporting instruction in the first perception reporting configuration, the second node transmits the first information to the first node, where the first information is used to indicate at least a frequency domain unit that satisfies the first characteristic. The first node instructs the second node to report the first information, enabling the first node to flexibly control the entire perception configuration process.

[0337] The channel information is used to indicate the information of the channel corresponding to the frequency domain unit. The channel information includes the channel amplitude and / or angle of each frequency domain unit. The channel information also includes at least one of the delay, channel amplitude, and angle of the time domain channel corresponding to the frequency domain unit. The perception parameter is used to indicate information related to the perception signal. The perception parameter includes at least one of speed, Doppler, distance, delay, and angle. Doppler is used to indicate the Doppler shift of the perception signal, that is, the difference between the transmit frequency and the receive frequency of the perception signal. The instantaneous perception parameter represents the perception parameter measured within the agreed time unit. The agreed time unit can be one or more subframes, one or more time slots, one or more symbols, etc. The perception parameter feature is used to indicate the measurement characteristics of the perception parameter, that is, how often the perception parameter is measured and how long the measurement time is. The perception parameter features include frequency, periodic components, etc.

[0338] In some embodiments, the second sensing reporting configuration includes a sensing result configuration, which is used to instruct the second node to collect sensing results related to the sensing result configuration on frequency domain units based on the second sensing signal configuration.

[0339] In some embodiments, the first receiving module 620 is configured to receive a perception reporting configuration sent by the first node.

[0340] In summary, the apparatus provided in the embodiments of the present application instructs a second node to report a perception result through a perception reporting configuration. The second node can selectively measure and report the perception result based on the perception result configuration sent by the first node. This allows the first node to flexibly configure the required perception result type. Furthermore, by collecting perception result types based on the perception result configuration rather than directly collecting all perception result types, energy consumption of both the first and second nodes can be reduced.

[0341] In some embodiments, the first perception signal configuration further includes a perception result configuration; or the second perception signal configuration further includes a transmission resource reporting indication. That is, the perception signal configuration includes the perception result configuration and / or the transmission resource reporting indication.
