[0029] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0030] It should be noted that in this disclosure, expressions such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplarily" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of expressions such as "exemplarily" or "for example" is intended to present the relevant concepts in a detailed manner.

[0031] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0032] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is simply a way to describe an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, A and B, and only B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0033] The integration of interawareness, enabling traditional communication systems to integrate both communication and perception capabilities, is a key evolutionary direction for next-generation communication technologies. Perception signals typically feature large bandwidth, high density of time and frequency domain resources, and long processing cycles. Configuring dedicated perception signals within a communication system consumes significant resource overhead. Traditional individual communication signals occupy relatively small frequency domain resources and are typically processed in time slots. Directly multiplexing a single communication signal for perception significantly impacts perception capabilities.

[0034] There are many types of communication signals and they are flexible to configure. If multiple or a variety of different communication signals can be used in combination for perception, there is no need to configure additional perception signals for perception.

[0035] Based on this, embodiments of the present disclosure provide a sensing method that determines and transmits at least one target signal to achieve sensing in conjunction with the at least one target signal. This method utilizes multiple existing signals for sensing, eliminating the need for configuring additional dedicated sensing signals. This reduces sensing resource overhead and improves spectrum resource utilization.

[0036] This disclosure can be applied to the following scenarios:

[0037] 1. Scenarios where communication and perception cover a large area, and the base station has strong multiple-in multiple-out (MIMO) (i.e., simultaneous multi-beam) capabilities. In this scenario, when the communication signal that can be used together does not meet the perception requirements in the airspace, an additional set of perception signals that meet the requirements can be generated through MIMO multi-beam, that is, the airspace requirements of perception and communication can be met simultaneously through space division, and the perception requirements for the time domain, frequency domain, power, and radio frequency initial phase of the combined signal can be met by adopting the scheduling restrictions, supplementary signals, or radio frequency index restrictions of the present disclosure. For example, in scenarios with large-scale coverage in smart cities, the urban environment has high communication resource requirements due to the high population density, and the perception resource requirements are also high due to factors such as the large number of vehicles, pedestrians, and low-altitude drones in the urban area.

[0038] 2. Scenarios where communication and perception resources are mostly covered by a limited number of beams. In this scenario, even if the perception transmitter does not have strong MIMO multi-beam capabilities, since communication and perception are concentrated in a limited number of beams most of the time, resource scheduling can easily meet the spatial domain requirements of the perception-based signal. The time domain, frequency domain, power, and RF initial phase requirements of the perception-based signal can be met by using the scheduling restrictions disclosed herein, supplementary signals, or the RF indicators of the base station itself. Examples include linear coverage scenarios such as highways, railways, urban main roads, low-altitude airways, and border lines, as well as indoor scenarios where fewer beams are required due to wider beams.

[0039] The network architecture of the communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiments of the present disclosure may include a synesthesia signal transmitter (referred to as a synesthesia transmitter, for example, including but not limited to a base station, a terminal), a communication receiving terminal (for example, including but not limited to a terminal, a base station) and a perception receiving terminal (for example, including but not limited to a terminal, a base station). The function of the synesthesia transmitter is to transmit the synesthesia signal through the wireless air interface according to the configuration requirements. The function of the communication receiving terminal is to receive the communication signal and process it to obtain the communication information. The function of the perception receiving terminal is to receive the synesthesia signal after being scattered by the perception target and perform perception processing to obtain perception information.

[0040] For example, in an example where both the interaural signal transmitter and the perception receiver are base stations, and the communication receiver is a terminal, Figure 1 illustrates a schematic diagram of the architecture of a communication system according to some embodiments. As shown in Figure 1 , communication system 10 includes base station 11 and terminal 12. Base station 11 and terminal 12 are communicatively connected.

[0041] In some embodiments, base station 11 is configured to provide wireless access services to multiple terminals 12. For example, a base station 11 provides a service coverage area (also referred to as a cell). Terminals 12 within this area can communicate with base station 11 via wireless signals, thereby receiving the wireless access services provided by base station 11. The service coverage areas of base stations 11 may overlap, and terminals 12 within the overlapping areas can receive wireless signals from multiple base stations 11.

[0042] In some embodiments, the base station 11 is configured to send a sensing signal, receive a signal scattered by a sensing target, and perform sensing processing to obtain sensing information.

[0043] In some embodiments, base station 11 can connect to multiple terminals 12. For example, base station 11 can connect to terminal 12 and terminal 12. Terminal 12 and terminal 12 can be located in the same cell, or in different cells. That is, one base station 11 can provide network services to terminal 12 in one cell, or can provide network services to terminals 12 in multiple cells simultaneously.

[0044] In some embodiments, the base station 11 can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network side devices such as primary cells and secondary cells.

[0045] In some embodiments, the terminal 12 can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may sometimes also be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., but the embodiments of the present disclosure are not limited to this.

[0046] In some embodiments, a base station may transmit a sensing signal to sense a target, and simultaneously receive an echo signal from the target in response to the sensing signal, and process the echo signal to obtain sensing information. Alternatively, a base station may transmit a sensing signal to sense a target, and a terminal may receive an echo signal from the target in response to the sensing signal, and process the echo signal to obtain sensing information.

[0047] Figure 2 is a flow chart of a method for sensing according to some embodiments. Exemplarily, the method for sensing provided by the present disclosure can be applied to the network architecture shown in Figure 1 , for example, can be applied to the base station in Figure 1 .

[0048] As shown in FIG2 , the method for sensing provided by the present disclosure may include: S201 to S202 .

[0049] S201: Determine at least one target signal.

[0050] Communication resources and sensing resources of at least one target signal overlap. At least one target signal is used for joint sensing.

[0051] S202: Send at least one target signal.

[0052] In the embodiment of the present disclosure, when perception is required, the synaesthesia transmitting end may obtain perception resources, combine at least one target signal with the perception resources, and send the signal, thereby realizing the perception function and communication function of surrounding targets.

[0053] In some embodiments, the at least one target signal includes at least one of the following: a communication signal, a supplementary signal. The communication signal may be a demodulation reference signal (DMRS), a positioning reference signal (PRS), a remote interference management reference signal (RIM-RS), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), a data signal, etc. The supplementary signal may include at least one of the following: a perception signal, a signal having the format of a communication signal and not carrying communication information (i.e., a virtual communication signal).

[0054] It should be noted that at least one target signal includes a communication signal, so sending at least one target signal can simultaneously achieve the functions of communication and perception.

[0055] It should be understood that the virtual communication signals referred to here refer to signals generated according to the communication signal format (including but not limited to communication reference signals, calibration signals, data signals, etc.), but in reality, these communication signals cannot be used to transmit real information. For example, a reference signal or data signal is configured to be sent to a virtual terminal to assist in perception, but in reality, this virtual terminal does not exist. Therefore, this virtual communication signal does not have the traditional information communication capability. Pure perception signals include but are not limited to linear frequency modulation signals and phase coded signals used by traditional radar.

[0056] In some embodiments, the technical solution provided by the present disclosure further includes: determining the perception resources based on the configuration information of the perception resources.

[0057] In some embodiments, the configuration information of the sensing resource includes at least one of the following: a frequency domain configuration parameter of the sensing resource, a time domain configuration of the sensing resource, and a beam identifier (BeamID) of the sensing resource.

[0058] In some embodiments, the frequency domain configuration parameters of the sensing resource include at least one of the following: bandwidth, starting position in the frequency domain, ending position in the frequency domain, and comb_size. The comb_size mentioned here can be understood as the resource element (RE) interval of the signal in the frequency domain, which can be used to characterize the frequency domain resource density of the signal. When the comb_size is comb_size, it means that there is a valid signal on only one RE with equal intervals on each comb_size RE.

[0059] It should be understood that the end position in the frequency domain configuration parameters in the frequency domain can also be determined based on the starting position in the frequency domain and the number of REs (or resource blocks) occupied by the perceived resources, or based on the starting position in the frequency domain and the bandwidth.

[0060] In some embodiments, the time domain configuration parameters of the sensing resource include at least one of the following: Doppler processing duration, the interval between two consecutive time-frequency units in the sensing resource (i.e., the time difference between two adjacent time-frequency units), the position of each time domain unit, the position of the target time domain unit and the intervals of other time domain units relative to the target time domain unit, and the distribution rule of the time domain units. The distribution rule of the time domain units can be used to indicate how the time domain units are configured according to a non-uniform period, for example, the intervals of the time domain units are distributed according to an arithmetic progression.

[0061] In some embodiments, the configuration information of the sensing resources is determined in one of the following ways: predefined, self-configured, or configured by another node. That is, the synaesthesia originating node can determine the configuration information in a predefined manner, or obtain the configuration information based on user input, or receive configuration information sent by another nearby node (e.g., a base station).

[0062] For example, FIG3 is a schematic diagram of a distribution of sensing resources according to some embodiments. As shown in FIG3, it includes multiple sensing resource blocks, each of which corresponds to a time domain unit and a frequency domain unit. In the time domain, it includes N t Time domain units, numbered from left to right as 0, 1, ..., N t -1. The interval between two adjacent time domain units is T SRI The starting position in the time domain is t start , the end position is t end , t start With t end The time between is the Doppler processing time. In the frequency domain, including N f Frequency domain units, numbered from bottom to top as 0, 1…, N f-1. The interval between two adjacent frequency domain units is comb_size. The starting position in the frequency domain is k start , the end position is k end , k start With k end The difference between them multiplied by the sparseness multiplied by the subcarrier spacing is the bandwidth.

[0063] In some embodiments, the power spectral density of each target signal in the at least one target signal is the same. It should be understood that the purpose of having the same power spectral density of the target signals used together is to ensure that the power or SNR of the echo signal corresponding to each target signal in the at least one target signal is substantially the same, thereby ensuring that the SNR, peak-to-average ratio, main-lobe-to-sidelobe ratio, or sidelobe ratio after Doppler processing meet perception requirements.

[0064] In some embodiments, each target signal in at least one target signal is transmitted using the same spatial beam. It should be understood that the shared spatial beam identifiers of the target signals are identical to ensure that the power of the transmitted signal reaching the target and background is the same within a sensing resource or Doppler processing duration.

[0065] In some embodiments, the initial RF phases of the target signals in at least one target signal are the same. It should be understood that the initial RF phases of the target signals used together are the same. This restriction is used to meet the requirements of perception scenarios such as A transmits and B receives, such as scenarios where the base station transmits and the terminal receives, or where the terminal transmits and the base station receives. The purpose is to avoid the impact of RF phase errors on the perception receiving end (for example, in the A transmits and B receives scenario, if the initial RF phase of the transmitting end changes, then the receiving end will have adverse effects such as reduced SNR of the perceived target, increased side lobes, and widened main lobes when performing perception Doppler processing).

[0066] In some embodiments, the communication resource satisfies at least one of the following in the frequency domain: the communication resource is continuous in the frequency domain; the frequency domain starting position of the communication resource is less than or equal to the frequency domain starting position of the perception resource; the frequency domain ending position of the communication resource is greater than or equal to the frequency domain ending position of the perception resource; the bandwidth of the communication resource is greater than or equal to the bandwidth of the perception resource; the sparseness (comb_size) of the communication resource is less than or equal to the sparseness of the perception resource.

[0067] It should be noted that, in order to enable the communication resources to meet the above conditions, the technical solution of the present disclosure may determine at least one target signal in the following manner.

[0068] In some embodiments, the sensing resource includes multiple frequency domain units in the frequency domain, and the determining of at least one target signal in the above S201 includes steps a1 to c1.

[0069] Step a1: for each frequency domain unit among the multiple frequency domain units included in the sensing resource in the frequency domain, if there is a communication signal to be transmitted on the frequency domain unit, determine whether the frequency domain resource corresponding to the communication signal to be transmitted covers the frequency domain unit;

[0070] Step b1: If the judgment result is yes, the communication signal to be transmitted is used as the target signal corresponding to the frequency domain unit;

[0071] Step c1: If the judgment result is no, the communication signal to be transmitted and the supplementary signal are used as the target signal corresponding to the frequency domain unit.

[0072] In some embodiments, in the above step a1, if there is no communication signal to be transmitted, then at least one target signal is determined in the above S201, and step d1 is also included: when there is no communication signal to be transmitted on the frequency domain unit, the supplementary signal is used as the target signal corresponding to the frequency domain unit.

[0073] In one implementation, if there is no available communication signal on a certain frequency domain unit (for example, the frequency domain is discontinuous, the frequency domain width is insufficient, etc.), if the perception performance requirements are not high or acceptable, the signal on the frequency domain unit can be not used, and the perception receiving end can be informed through signaling.

[0074] It should be noted that perceptual quality can be guaranteed only if a usable signal exists in each of the multiple frequency domain units in the perception resource. Therefore, if the frequency domain corresponding to the communication signal to be transmitted on the frequency domain unit does not meet the frequency domain width of the frequency domain unit, a supplementary signal is required to ensure that the frequency domain resources corresponding to the communication signal to be transmitted and the supplementary signal meet the frequency domain width of the frequency domain unit, thereby increasing the frequency domain density of the overall perception signal and improving perception performance.

[0075] For example, FIG4 is a frequency domain schematic diagram of selecting a target signal according to some embodiments. As shown in FIG4, the width of a frequency domain unit is k in the figure. start -k endFor case 1, there is a communication signal to be transmitted on the frequency domain unit, and the frequency domain width corresponding to the communication signal is greater than or equal to the width of the frequency domain unit, then the communication signal can be determined to be the target signal. For case 2, there are communication signal 1 and communication signal 2 on the frequency domain unit, and the two communication signals do not overlap in the frequency domain. As can be seen from the figure, the frequency domain width corresponding to communication signal 1 and communication signal 2 is greater than or equal to the width of the frequency domain unit, then the two communication signals can be determined to be the target signal. For case 3, it is similar to case 2, but the difference is that there is partial overlap between the two communication signals in the frequency domain. For case 4, although there is a communication signal, the frequency domain width of the communication signal is less than the width of the frequency domain unit, then a supplementary signal needs to be added so that the frequency domain width corresponding to the communication signal and the supplementary signal is greater than or equal to the width of the frequency domain unit. For case 5, there is no communication signal to be transmitted, then a supplementary signal can be added, and the frequency domain width of the supplementary signal must be greater than or equal to the width of the frequency domain unit.

[0076] Figure 5 is a schematic diagram of a thinning-out of a combined target signal according to some embodiments. As shown in Figure 5 , in the frequency domain, the left side shows the expected distribution of the combined target signal, the middle shows the distribution after combining multiple different communication signals, and the right side shows the distribution after combining a communication signal and a supplemental signal.

[0077] In some embodiments, the sensing resource includes multiple first time domain units in the time domain; the determining of at least one target signal in the above S201 includes steps a2 to c2.

[0078] Step a2: for each first time domain unit among the multiple first time domain units included in the sensing resource in the time domain, if there is a communication signal to be transmitted on the first time domain unit, determine whether the time domain resource corresponding to the communication signal to be transmitted covers the first time domain unit;

[0079] Step b2: If the judgment result is yes, use the communication signal to be transmitted as the target signal corresponding to the first time domain unit;

[0080] Step c2: If the judgment result is no, the communication signal to be transmitted and the supplementary signal are used as the target signal corresponding to the first time domain unit.

[0081] In some embodiments, if there is no communication signal to be transmitted in the above step a2, at least one target signal is determined in the above S201, and step d2 is also included: when there is no communication signal to be transmitted on the first time domain unit, the supplementary signal is used as the target signal corresponding to the first time domain unit.

[0082] In some embodiments, if there is no communication signal to be transmitted in step a2, determining at least one target signal in step S201 further includes step e2: if there is no communication signal to be transmitted in the first time domain unit, determining the target signal in a second time domain unit adjacent to the first time domain unit. The second time domain unit is a time domain location closest to the first time domain unit.

[0083] In one implementation, if there is no available communication signal on a first time domain unit (for example, the frequency domain is discontinuous, the frequency domain width is insufficient, etc.), if the perception performance requirements are not high or acceptable, the signal on the first time domain unit can be not used, and the perception receiving end can be informed through signaling.

[0084] For example, the description is made in conjunction with FIG6. The expected time domain position distribution of the combined target signal is shown in FIG6, and the time domain unit is numbered t n-3 to t n+3 In one scenario, if a time domain unit lacks a signal to be transmitted, or the time domain resource of the signal to be transmitted does not meet the conditions (for example, discontinuity in the time domain, insufficient time domain length, etc.), a supplementary signal needs to be configured. For example, in Figure 6, corresponding to t n If there is no available communication signal on the first time domain unit at the time instant, an additional supplementary signal is configured for joint use. In another scenario, if the signal to be transmitted on a certain time domain unit is unavailable or occupied by other signals, the communication signal to be transmitted on the nearest (previous or next) second time domain unit can be found for joint use. For example, in FIG6 corresponding to t n If the signal in the first time domain unit at a moment is unavailable, the target signal is determined in the adjacent previous time domain unit.

[0085] Figure 7 is a flow chart of a method for sensing according to some embodiments. Exemplarily, the method for sensing provided by the present disclosure can be applied to the network architecture shown in Figure 1 , for example, it can be applied to the base station in Figure 1 as a sensing receiving end.

[0086] As shown in FIG. 7 , the method for sensing provided by the present disclosure may include: S701 to S702 .

[0087] S701. Receive at least one target signal.

[0088] Communication resources and sensing resources of at least one target signal overlap, and at least one target signal is used for joint sensing.

[0089] S702: Acquire perception information based on at least one target signal.

[0090] In the embodiment of the present disclosure, the sensing receiving end may process at least one target signal for a duration corresponding to the sensing resource (e.g., the aforementioned Doppler processing duration) to obtain sensing information. For example, the sensing information may be positioning information of the sensing target.

[0091] For details about the target signal and sensing resources, please refer to the description of the sensing originator, which will not be repeated here.

[0092] In some embodiments, the communication receiving end may receive at least one target signal, process the target signal in a time period required for communication (eg, a time slot as a period), and obtain communication information.

[0093] The technical solution of the present disclosure is described below in conjunction with scenarios.

[0094] Scenario 1: Perception base station sends and base station receives.

[0095] Step 1. The base station selects the target signal according to the communication and perception requirements (i.e., the configuration information of the aforementioned perception resources). For example, the bandwidth of the perception resource is 100 MHz, located at carrier 0, the interval of the perception resource time domain unit is 0.25 ms, the Doppler processing time of the perception resource is 32 ms (i.e., a total of 128 perception signals are required in the time domain), and the comb size of the perception resource is comb_size = 2. The available target signals within 32 ms are reasonably allocated. The communication signal here is one or more types of signals, such as DMRS, PRS, CSI-RS, RIM-RS, data signals, etc.

[0096] Step 2. When the communication signal within the required 32ms does not meet the requirements of the perception resources, the time-frequency resources can be adjusted according to the relevant descriptions of the above steps a1 to d1, and steps a2 to e2, so that at least one determined target signal can meet the requirements of the perception resources, and the scheduling information corresponding to the adjusted time-frequency resources can be obtained.

[0097] Step 3: The base station transmits the adjusted scheduling information to the corresponding terminal (which can be one or more different terminals), and then the base station transmits the corresponding target signal on the adjusted time-frequency resources, including but not limited to communication signals, supplementary signals, etc.

[0098] Step 4: The terminal receives and processes the communication signal according to the scheduling information and obtains the corresponding communication information.

[0099] Step 5: The base station receives the sensing signal reflected by the sensing target, processes the corresponding signal, and obtains the sensing information.

[0100] Scenario 2: The perception terminal sends and the terminal receives.

[0101] Step 1: The terminal transmits a communication and sensing scheduling request to the base station. The base station selects target signals based on communication and sensing requirements, such as a 200MHz sensing resource bandwidth located at carrier 0, a 0.25ms sensing resource time domain unit interval, a 64ms Doppler processing time for the sensing resource (i.e., a total of 256 sensing signals are required in the time domain), and a comb size of 1 for the sensing resource. The base station then rationally allocates available target signals within the 64ms period. Communication signals here are one or more types of signals, such as DMRS, PRS, CSI-RS, RIM-RS, and data signals.

[0102] Step 2. When the communication signal within the required 64ms does not meet the requirements of the perception resources, the time-frequency resources can be adjusted according to the relevant descriptions of the above steps a1 to d1, and steps a2 to e2, so that at least one determined target signal can meet the requirements of the perception resources, and the scheduling information corresponding to the adjusted time-frequency resources can be obtained.

[0103] Step 3: The base station transmits the adjusted scheduling information to the corresponding terminal, and then the terminal transmits the corresponding target signal on the adjusted time-frequency resources, including but not limited to communication signals, supplementary signals, etc.

[0104] Step 4: The base station receives and processes the communication signal according to the scheduling information and obtains the corresponding communication information.

[0105] Step 5: The terminal receives the sensing signal reflected by the sensing target, processes the corresponding signal, and obtains the sensing information.

[0106] Scenario 3: Perception base station sends and terminal receives.

[0107] Step 1. The base station selects the target signal according to the communication and perception requirements. For example, the bandwidth of the perception resource is 100 MHz, located at carrier 0, the interval of the perception resource time domain unit is 0.25 ms, the Doppler processing time of the perception resource is 32 ms (ie, a total of 128 perception signals are required in the time domain), and the comb size of the perception resource is comb_size = 2. The available target signals within 32 ms are reasonably allocated. The communication signal here is one or more types of signals, such as DMRS, PRS, CSI-RS, RIM-RS, data signals, etc.

[0108] Step 2. When the communication signal within the required 64ms does not meet the requirements of the perception resources, the time-frequency resources can be adjusted according to the relevant descriptions of the above steps a1 to d1, and steps a2 to e2, so that at least one determined target signal can meet the requirements of the perception resources, and the scheduling information corresponding to the adjusted time-frequency resources can be obtained.

[0109] Step 3: The base station transmits the adjusted scheduling information to the corresponding terminal, and then transmits the corresponding target signal on the adjusted time-frequency resources, including but not limited to communication signals, supplementary signals, etc.

[0110] Step 4: The terminal receives and processes the communication signal according to the scheduling information and obtains the corresponding communication information.

[0111] Step 5: The terminal receives the sensing signal reflected by the sensing target, processes the corresponding signal, and obtains the sensing information.

[0112] Scenario 4: The perception terminal sends and the base station receives.

[0113] Step 1: The terminal transmits a communication and sensing scheduling request to the base station. The base station determines the selection signal based on the communication and sensing requirements, such as the sensing resource bandwidth of 100 MHz, located at carrier 0, the interval of the sensing resource time domain unit of 0.25 ms, the Doppler processing time of the sensing resource of 32 ms (i.e., a total of 128 sensing signals are required in the time domain), and the comb size of the sensing resource comb_size = 2. The base station reasonably allocates the available target signals within 32 ms. The communication signal here is one or more types of signals, such as DMRS, PRS, CSI-RS, RIM-RS, data signals, etc.

[0114] Step 2. When the communication signal within the required 64ms does not meet the requirements of the perception resources, the time-frequency resources can be adjusted according to the relevant descriptions of the above steps a1 to d1, and steps a2 to e2, so that at least one determined target signal can meet the requirements of the perception resources, and the scheduling information corresponding to the adjusted time-frequency resources can be obtained.

[0115] Step 3: The base station transmits the adjusted scheduling information to the corresponding terminal, and then the terminal transmits the corresponding target signal on the adjusted time-frequency resources, including but not limited to communication signals, supplementary signals, etc.

[0116] Step 4: The base station receives and processes the communication signal according to the scheduling information and obtains the corresponding communication information.

[0117] Step 5: The base station receives the sensing signal reflected by the sensing target, processes the corresponding signal, and obtains the sensing information.
