[0002] This application relates to the field of communication sensing, and more particularly to a sensing method, device, storage medium, and program product. Background Technology

[0003] Currently, the integration of communication and sensing is an important technological direction. Sensing functions can be accomplished through communication signals; or communication can be assisted based on sensing results.

[0004] One existing sensing method involves a transmitter sending a sensing signal (e.g., channel state information-reference signal, CSI-RS) to a receiver. This method is based on a single carrier and a single receiver to sense target motion. However, the sensing results obtained using this method are susceptible to time-varying channel effects caused by Doppler shift, making it difficult to accurately reflect the motion of the sensed target.

[0005] Another existing sensing method involves a transmitter sending sensing signals to two receivers. This method, based on a single carrier and dual receivers, can overcome the problems of time-varying channels and random phase caused by Doppler shift. However, this method requires two receivers, increasing hardware costs.

[0006] Therefore, how to accurately perceive the target with relatively low hardware cost is an urgent problem to be solved. Summary of the Invention

[0007] This application provides a sensing method, apparatus, storage medium, and program product that accurately achieves target sensing with relatively low hardware cost.

[0008] Firstly, a sensing method is provided, which can be executed by a sensing receiver or by a module (e.g., processor, chip, chip system, circuit, etc.) in the sensing receiver.

[0009] The method includes: receiving a first sensing signal, the first sensing signal including a first sub-signal and a second sub-signal, the first sub-signal being carried on a first resource and the second sub-signal being carried on a second resource; and determining information about a sensing target based on the first sub-signal and the second sub-signal.

[0010] Alternatively, the method includes: receiving a first sensing signal on a first resource set, the first resource set including a first resource and a second resource, the first sensing signal including a first sub-signal and a second sub-signal, the first resource carrying the first sub-signal and the second resource carrying the second sub-signal; and determining information about a sensing target based on the first sub-signal and the second sub-signal.

[0011] Using this method, the sensing receiver receives a sensing signal transmitted by the sensing transmitter on a first resource set. This sensing signal includes a first sub-signal and a second sub-signal, which are carried on different resources. This allows the sensing receiver to determine the information of the sensing target based on the first and second sub-signals, thus eliminating the need for multiple sensing receivers and reducing hardware costs. Furthermore, determining the information of the sensing target based on the first and second sub-signals overcomes the problems of time-varying channels and random phases caused by Doppler, ensuring the accuracy of the sensing.

[0012] In conjunction with the first aspect, in one possible design, a first sensing signal is received, the first sensing signal including a first sub-signal and a second sub-signal, the first sub-signal being carried on a first resource and the second sub-signal being carried on a second resource; and information about the sensing target is determined based on at least one of information from the conjugate multiplication of the first sub-signal and the second sub-signal, information from the amplitude division, and information from the phase subtraction.

[0013] Alternatively, the method includes: receiving a first sensing signal on a first resource set, the first resource set including a first resource and a second resource, the first sensing signal including a first sub-signal and a second sub-signal, the first resource carrying the first sub-signal and the second resource carrying the second sub-signal; and determining information about a sensing target based on at least one of information from the conjugate multiplication of the first sub-signal and the second sub-signal, information from the amplitude division, and information from the phase subtraction.

[0014] Using this method, the sensing receiver receives a sensing signal transmitted by the sensing transmitter on a first resource set. This sensing signal includes a first sub-signal and a second sub-signal, which are carried on different resources. This allows the sensing receiver to determine the information of the sensing target based on at least one of the following: information from the conjugate multiplication of the first and second sub-signals, information from the amplitude division, and information from the phase subtraction. This eliminates the need for multiple sensing receivers, reducing hardware costs. Furthermore, determining the information of the sensing target based on at least one of the following overcomes the problems of time-varying channels and random phases caused by Doppler, ensuring the accuracy of the sensing.

[0015] In conjunction with the first aspect, in another possible design, the first sub-signal and the second sub-signal have a quasi-colocation (QCL) relationship.

[0016] With this design, the first and second sub-signals experience similar channels and can be used for joint processing, thereby overcoming the problems of time-varying channels and random phases caused by Doppler.

[0017] In conjunction with the first aspect, in another possible design, the information of the sensing target includes at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, speed information of the sensing target, and angle information of the sensing target.

[0018] In conjunction with the first aspect, in another possible design, the first sensing signal is used to determine information about the sensing target; or, the first sensing signal is used to determine at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, speed information of the sensing target, and angle information of the sensing target.

[0019] In conjunction with the first aspect, in another possible design, the motion information of the perceived target includes whether the perceived target is moving, or the distance the perceived target has moved; the speed information of the perceived target includes the speed of the perceived target, or the number of breaths the perceived target takes per minute.

[0020] In conjunction with the first aspect, in another possible design, the first sensing signal includes a signal received after the second sensing signal is reflected or scattered by the sensing target; or, the first sensing signal is a signal received after the second sensing signal is reflected or scattered by the sensing target; or, the first sensing signal is the second sensing signal; or the first sensing signal includes the second sensing signal; wherein the second sensing signal is transmitted by the sensing transmitter.

[0021] In conjunction with the first aspect, in another possible design, the first sub-signal includes a signal received after the third sub-signal is reflected or scattered by the sensing target; or, the first sub-signal is the third sub-signal; wherein the third sub-signal is transmitted by the sensing transmitter.

[0022] In conjunction with the first aspect, in another possible design, the second sub-signal includes the signal received after the fourth sub-signal is reflected or scattered by the sensing target; or, the second sub-signal is the fourth sub-signal; wherein the fourth sub-signal is transmitted by the sensing transmitter.

[0023] In conjunction with the first aspect, in another possible design, the change in the first sensing signal relative to the second sensing signal includes changes caused by reflection or scattering via the sensing target.

[0024] In conjunction with the first aspect, in another possible design, the change of the first sub-signal relative to the third sub-signal includes the change caused by reflection or scattering via the sensing target.

[0025] In conjunction with the first aspect, in another possible design, the change of the second sub-signal relative to the fourth sub-signal includes the change caused by reflection or scattering via the sensing target.

[0026] Using this design, information about the sensed signal can be determined based on changes in the sensed signal. For example, information about the sensed signal can be determined by changes in the amplitude and / or phase of the sensed signal.

[0027] In conjunction with the first aspect, in another possible design, the method further includes: smoothing and filtering the amplitude information of at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction; and / or smoothing and filtering the phase information of at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction.

[0028] Using this design, smoothing filtering can reduce the impact of noise on the sensing results. For example, it can remove the influence of high-frequency noise on the sensing results.

[0029] In conjunction with the first aspect, in another possible design, the method further includes: performing Fourier transform processing on the amplitude information of at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction, to determine the information of the sensing target; and / or performing Fourier transform processing on the phase information of at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction, to determine the information of the sensing target; and / or performing Multi-Signal Classification (MUSIC) processing on the amplitude information of at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction, to determine the information of the sensing target; and / or performing MUSIC processing on the phase information of at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction, to determine the information of the sensing target.

[0030] One method for processing amplitude information using FFT or MUSIC is to first determine the division information between the first and second sub-signals, and then perform FFT or MUSIC processing on the amplitude information of this division information. The division information is complex division information, which can be determined by dividing the amplitudes and subtracting the phases. Alternatively, one can first determine the amplitude division information between the first and second sub-signals, and then perform FFT or MUSIC processing on this amplitude division information.

[0031] Using this design, FFT or MUSIC processing can reflect information about the sensed target, such as the speed of its motion. This is because, taking conjugate multiplication as an example, information about the sensed target can be obtained from the information obtained by multiplying the first and second sub-signals conjugately. For example, as the target moves away from the sensing receiver (or sensing transmitter), the amplitude or phase of the information obtained by multiplying the first and second sub-signals conjugately fluctuates. The frequency of this fluctuation reflects the speed of the sensed target's motion. After FFT or MUSIC processing, its peak value corresponds to the frequency of this fluctuation. To distinguish the frequency of the signal from the frequency of the fluctuation, in this application, the frequency of the fluctuation is referred to as the motion frequency.

[0032] Similarly, the amplitude division and phase subtraction information also exhibit fluctuations as the target moves away from the sensing receiver (or sensing transmitter). Consequently, after FFT or MUSIC processing, the peak value corresponds to the motion frequency of the sensed target.

[0033] In conjunction with the first aspect, in another possible design, the first resource and the second resource have the same time domain but different frequency domains.

[0034] In conjunction with the first aspect, in another possible design, the first sensing signal is located in a first portion and / or a second portion of a portion of the bandwidth of the sensing transmitter, wherein the first portion of the bandwidth includes resource blocks in the portion of the bandwidth whose index is less than or equal to a first value, and the second portion of the bandwidth includes resource blocks in the portion of the bandwidth whose index is greater than or equal to a second value.

[0035] In conjunction with the first aspect, in another possible design, the first sensing signal is located in a first portion and / or a second portion of the partial bandwidth of the sensing receiver, wherein the first portion of the partial bandwidth includes at least one resource block whose index gradually increases from the resource block corresponding to the lowest index, and the second portion of the partial bandwidth includes at least one resource block whose index gradually decreases from the resource block corresponding to the highest index.

[0036] In conjunction with the first aspect, in another possible design, the first resource includes the highest resource unit with the highest resource block index in a portion of the bandwidth, and the second resource includes the lowest resource unit with the lowest resource block index in a portion of the bandwidth.

[0037] This design allows sensing signals to be transmitted on both sides of a portion of the bandwidth, while communication signals can be transmitted within continuous frequency domain units of that bandwidth. This facilitates resource allocation for communication signals and reduces the impact of sensing on communication.

[0038] In conjunction with the first aspect, in another possible design, the frequency resources of the first sensing signal are associated with at least one of the following parameters: the number of frequency units included in the first resource set, a first frequency difference, a sensing bandwidth, and a first frequency offset; wherein the first frequency difference is the frequency difference between any two frequency units among the plurality of frequency units included in the first resource set; and the first frequency offset is the frequency offset of the lowest frequency unit of the first sensing signal relative to the lowest frequency unit of a portion of the bandwidth, or the frequency offset of the lowest resource block of the first sensing signal relative to the lowest resource block of a portion of the bandwidth.

[0039] In conjunction with the first aspect, in another possible design, the frequency resources of the first resource and / or the second resource are associated with at least one of the following parameters: the number of frequency units included in the first resource and / or the second resource, the first frequency difference, the second frequency difference, the sensing bandwidth, the first frequency offset, and the second frequency offset; wherein, the first frequency difference is the frequency difference between every two frequency units among the plurality of frequency units included in the first resource set; the second frequency difference is the frequency difference between every two frequency units among the plurality of frequency units included in the first resource and / or the second resource; the first frequency offset is the first frequency offset of the lowest resource unit of the first sensing signal relative to the lowest resource unit of a portion of the bandwidth, or, the first frequency offset of the lowest resource block of the first sensing signal relative to the lowest resource block of a portion of the bandwidth; the second frequency offset is the frequency difference between the frequency unit with the smallest index in the first resource and the frequency unit with the smallest index in the second resource, or, the frequency difference between the frequency unit with the largest index in the first resource and the frequency unit with the largest index in the second resource.

[0040] This design allows for the allocation of appropriate resource sizes to sensing signals, ensuring that the resource sizes meet the needs of the sensing services. More sensing resources are allocated to critical sensing services, while less important services receive fewer. This, in turn, guarantees that all types of sensing services have adequate sensing resources from a system perspective, thus ensuring the reliability of sensing at the system level.

[0041] In conjunction with the first aspect, in another possible design, the first sensing signal is a periodically transmitted signal, the period being associated with information of the sensing service, wherein the information of the sensing service includes at least one of the following: sensing speed accuracy, sensing speed resolution, sensing distance accuracy, sensing distance resolution, maximum sensing speed, and maximum sensing distance.

[0042] In conjunction with the first aspect, in another possible design, the method further includes: receiving Y first sensing signals on Y first time units; and determining information about the sensing target based on Y first pieces of information, each of the Y first pieces of information being obtained based on the first sensing signals received on each of the Y first time units.

[0043] In conjunction with the first aspect, in another possible design, the method further includes: the first information being at least one of information obtained by multiplying the first sub-signal and the second sub-signal by their conjugates, information obtained by dividing the amplitudes, and information obtained by subtracting the phases.

[0044] In conjunction with the first aspect, in another possible design, the first resource has the same frequency resources on the Y first time units; and / or the second resource has the same frequency resources on the Y first time units.

[0045] In conjunction with the first aspect, in another possible design, the information obtained by performing Fourier transform or MUSIC transform on the amplitude information or phase information of the processed information of the first sub-signal and the second sub-signal in the Y first time units is the first sensing information. The processed information of the first sub-signal and the second sub-signal includes at least one of the following: information of conjugate multiplication of the first sub-signal and the second sub-signal, information of amplitude division, and information of phase subtraction. The first sensing information corresponds to at least one motion frequency. The information of the sensing target is determined based on a first value, which is the peak value in the first sensing information corresponding to at least one non-zero motion frequency among the at least one motion frequency.

[0046] This design, based on the peak value in the first sensing information corresponding to at least one non-zero motion frequency, determines the information of the sensing target, thus improving the reliability of sensing. Removing information with a zero motion frequency removes the sensing signal directly coupled from the sensing transmitter to the sensing receiver. This is because information with a zero motion frequency corresponds to the static component of the first sensing signal and does not include the information of the sensing target; correspondingly, information with non-zero motion frequencies corresponds to the dynamic component of the first sensing signal and includes the information of the sensing target. By determining the peak value of the first sensing information in the non-zero motion frequencies, the influence of the static component on the sensing result can be eliminated, meaning that the portion including the information of the sensing target can be extracted. For example, the static component includes the sensing signal transmitted from the sensing transmitter that arrives directly at the sensing receiver without being reflected or scattered by the sensing target. In actual sensing, the signal energy of this static component is very large; removing information with a zero motion frequency is equivalent to removing the information of this static component from the first sensing signal.

[0047] In conjunction with the first aspect, in yet another possible design, the first resource includes M. A A first frequency unit, the second resource including M A A second frequency unit, in each of the Y first time units, the first signal is carried by the M A A first frequency unit, the second signal being carried in the M A The second frequency unit, M A It is a positive integer.

[0048] In conjunction with the first aspect, in yet another possible design, the M A =1, the first sensing information has C first values, the C first values ​​are used to determine the information of C sensing targets, and C is a positive integer.

[0049] In conjunction with the first aspect, C is defaulted to 1, meaning that information about one perceived target is determined. This first perceived information has a first value, which is used to determine the information about the one perceived target.

[0050] In conjunction with the first aspect, in yet another possible design, the M A Greater than 1, M A The M first sensing information comprises N first sensing information pieces, wherein at least one of the N first sensing information pieces has a first value greater than at least one of the X first sensing information pieces, and the X first sensing information pieces are the M A The perceived information other than the N first perceived information pieces, M A Each piece of perceived information is carried on M in the Y first time units. AThe first sub-signal on the first frequency unit and carried in M A The information obtained by performing Fourier transform or MUSIC transform on the amplitude or phase information of the second sub-signal processed on the second frequency unit, where N and X are both positive integers.

[0051] In conjunction with the first aspect, in yet another possible design, the M A Greater than 1, the M A Each piece of perceived information includes at least one peak, M A The perceived information includes N first perceived information items, wherein the N first perceived information items include C largest first values ​​among the at least one peak value, and the M A Each piece of perceived information is carried on M in the Y first time units. A The first sub-signal on the first frequency unit and carried in M A The information obtained by performing Fourier transform or MUSIC transform on the amplitude or phase information of the second sub-signal processed on the second frequency unit, where N and X are both positive integers.

[0052] Using this design, M A When the value is greater than 1, it's equivalent to allocating more frequency domain resources to sensing services. M A Each piece of perceived information includes at least one peak; information with a higher peak can be used to determine the information of the perceived target. This helps avoid interference affecting the perception results.

[0053] In conjunction with the first aspect, in another possible design, N=1, the first sensing information has a first value, which is used to determine information about a sensing target.

[0054] In conjunction with the first aspect, in another possible design, N is greater than 1, and the N first sensing information have C first values, which are used to determine the information of the C sensing targets.

[0055] In conjunction with the first aspect, in yet another possible design, the M A If the value is greater than 1, the first perceived information is M. A The perceptual information with the largest peak value among the perceptual information, namely M A Each piece of perceived information is carried on M in the Y first time units. A The first sub-signal on the first frequency unit and carried in M A The information obtained by performing Fourier transform or MUSIC transform on the amplitude or phase information of the second sub-signal processed on the second frequency unit.

[0056] In conjunction with the first aspect, in another possible design, the first sensing information has C first values, which are used to determine information about C sensing targets, where C is a positive integer.

[0057] In conjunction with the first aspect, in another possible design, receiving the first sensing signal includes: receiving the first sensing signal on the first resource set at a first port; or, receiving the first sensing signal on the first resource set at a first radio frequency channel; or, receiving the first sensing signal on the first resource set at a first radio frequency integrated circuit; or, receiving the first sensing signal on the first resource set at a first baseband channel; or, receiving the first sensing signal on the first resource set at a first antenna; or, receiving the first sensing signal on the first resource set at a first antenna element; or, receiving the first sensing signal on the first resource set at a first antenna array element; or, receiving the first sensing signal on the first resource set at a first remote radio frequency unit; or, receiving the first sensing signal on the first resource set at a first wireless unit.

[0058] Using this design, existing technologies overcome the problems of time-varying channels and random phases caused by Doppler by using two sensing receivers. However, in this scheme, reception is completed using only one sensing receiver, which overcomes the above problems while saving hardware overhead for the sensing receiver compared to existing technologies.

[0059] In conjunction with the first aspect, in another possible design, the method further includes: receiving first perception request information, wherein the first perception request information is used to request configuration information of the perception signal; or, sending second perception request information, wherein the second perception request information is used to request configuration information of the perception signal; wherein the first perception request information and the second perception request information include at least one of the following: perception scene, perception service type, confidence level, accuracy of positioning estimation, accuracy of velocity estimation, distance resolution, velocity resolution, maximum distance, maximum velocity, maximum perception service latency, refresh rate, missed detection rate, false alarm rate; the configuration information of the perception signal includes at least one of the following: frequency resources of the first resource set, time domain resources of the first resource set, code domain resources of the first resource set, frequency resources of the first resource and / or the second resource, time domain resources of the first resource and / or the second resource, and code domain resources of the first resource and / or the second resource.

[0061] This design allows for the allocation of appropriate resource sizes to sensing signals, ensuring that the resource size aligns with the needs of the sensing services. More sensing resources are allocated to critical sensing services, while less important services receive fewer. This system-wide approach guarantees that all types of sensing services have adequate resources, ensuring system-level reliability. Sensing transmitters and / or receivers can request sensing resources based on the needs of the sensing services, improving system efficiency.

[0063] Secondly, a sensing method is provided, which can be executed by a sensing transmitter or by a module (such as a processor, chip, chip system, circuit, etc.) in the sensing transmitter.

[0064] The method includes: sending a second sensing signal, the second sensing signal including a third sub-signal and a fourth sub-signal, the third sub-signal being carried on a first resource, the fourth sub-signal being carried on a second resource, and the second sensing signal being used to determine information about the sensing target.

[0065] Alternatively, the method includes: transmitting a second sensing signal on a first resource set, the first resource set including a first resource and a second resource, the second sensing signal including a third sub-signal and a fourth sub-signal, the first resource carrying the third sub-signal, the second resource carrying the fourth sub-signal, the second sensing signal being used to determine information about a sensing target.

[0066] Using this method, the sensing transmitter sends a second sensing signal to the sensing receiver on a first resource set. This second sensing signal includes a third sub-signal and a fourth sub-signal, which are carried on different resources. This allows the sensing receiver to determine the information of the sensing target based on the first and second sub-signals, thus eliminating the need for multiple sensing receivers and reducing hardware costs. Furthermore, determining the information of the sensing target based on the first and second sub-signals overcomes the problems of time-varying channels and random phases caused by Doppler, ensuring the accuracy of the sensing.

[0067] In conjunction with the second aspect, in one possible design, the information of the sensing target includes at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, speed information of the sensing target, and angle information of the sensing target.

[0105] This method allows for the allocation of appropriate resource sizes to sensing signals, ensuring that the resource size aligns with the needs of the sensing services. More sensing resources are allocated to critical sensing services, while fewer resources are allocated to less critical services. This, in turn, guarantees that all types of sensing services have adequate sensing resources from a system perspective, and ensures the reliability of sensing at the system level.

Furthermore, the allocation of sensing resources can be based on direct allocation from network devices or on requests from the sensing transmitter and / or receiver. Both the transmitter and receiver can request sensing resources according to the needs of the sensing services, improving system efficiency. It also facilitates allocating slightly more sensing resources to important sensing services and correspondingly, slightly fewer sensing resources to less important services.

[0204] The scheme of this application will be further described below with reference to the accompanying drawings.

[0205] The technical solution provided in this application can be applied to various communication systems, such as fifth-generation (5G) communication systems. th This technology can be applied to various scenarios, including 5G mobile communication systems, future evolution systems, and converged communication systems, as well as existing communication systems. The application scenarios of the technical solutions provided in this application can include multiple areas, such as machine-to-machine (M2M), macro-micro communication, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC), and massive machine-type communication (mMTC). These scenarios may include, but are not limited to, communication between terminal devices, communication between network devices, and communication between network devices and terminal devices. Network devices include access network devices and core network devices. The following descriptions use examples of communication between network devices and terminal devices.

[0206] Figure 1 illustrates a possible, non-limiting communication system. As shown in Figure 1, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. The communication system 1000 may also include an Internet 300. RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal device (120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal device 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 200. The core network devices in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0207] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G mobile communication systems, or future-oriented evolution systems. RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0208] RAN node 110, also known as network equipment, access network equipment, RAN entity, or access node, constitutes part of the communication system and assists terminal equipment in achieving wireless access. Multiple RAN nodes 110 in the communication system 1000 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal equipment 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminal equipment 120j accessing RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal equipment. RAN node 110 and terminal equipment 120 are sometimes referred to as sensing devices. For example, network elements 110a and 110b in Figure 1 can be understood as sensing devices with base station functions, and network elements 120a-120j can be understood as sensing devices with terminal equipment functions.

[0209] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6th-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system. A RAN node can be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Optionally, a RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0210] In another possible scenario, multiple RAN nodes assist terminal devices in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), central unit-control planes (CU-CPs), central unit-user planes (CU-UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0211] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open-centralized unit (O-CU), DU can also be called an open-distributed unit (O-DU), CU-CP can also be called an open-centralized unit-control plane (O-CU-CP), CU-UP can also be called an open-centralized unit-user plane (O-CU-UP), and RU can also be called an open-radio unit (O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0212] Terminal equipment can also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal device, access terminal, subscriber unit, user station, user terminal, wireless communication equipment, user agent, or user device, etc. Terminal equipment can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminal equipment can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the form of the terminal equipment.

[0213] Communication between network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0214] Base stations and terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminal equipment.

[0215] The roles of base stations and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 through 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol. In this case, relative to 110a, 120i is also a base station. Therefore, both base stations and terminal devices can be collectively referred to as sensing devices. 110a and 110b in Figure 1 can be called sensing devices with base station functions, and 120a-120j in Figure 1 can be called sensing devices with terminal device functions.

[0216] In this embodiment, the base station is also referred to as a network device. The apparatus for implementing the functions of the network device can be a network device itself; it can also be an apparatus capable of supporting the network device in implementing those functions, such as a chip system, hardware circuit, software module, or a hardware circuit plus a software module. This apparatus can be installed in the network device or used in conjunction with the network device. In this embodiment, the example of a network device being used to implement the functions of the network device is used only and does not constitute a limitation on the solutions of this embodiment.

[0217] Furthermore, in this embodiment, the UE is also referred to as a terminal device. The apparatus for implementing the functions of the terminal device can be the terminal device itself; it can also be an apparatus capable of supporting the terminal device in implementing those functions, such as a chip system, hardware circuit, software module, or a hardware circuit plus a software module. This apparatus can be installed in the terminal device or used in conjunction with the terminal device. In this embodiment, only the apparatus for implementing the functions of the terminal device is described as a terminal device, and this does not constitute a limitation on the solutions of this embodiment.

[0218] It should be understood that the number and type of each device in the communication system shown in Figure 1 are for illustrative purposes only, and this application is not limited thereto. In actual applications, the communication system may include more terminal devices, more access network devices, and other network elements, such as core network devices and / or network elements used to implement artificial intelligence functions.

[0219] It is understandable that all or part of the functions implemented by one or more of the terminal devices, access network devices, core network devices, or network elements used to implement artificial intelligence functions can be virtualized, that is, implemented through one or more of dedicated or general-purpose processors and corresponding software modules. Among these, the terminal devices and access network devices involve air interface transmission, and the transmit and receive functions of this interface can be implemented in hardware. Core network devices, such as operation administration and maintenance (OAM) network elements, can also be virtualized. Optionally, one or more of the functions of the virtualized terminal devices, access network devices, core network devices, or network elements used to implement artificial intelligence functions can be implemented by cloud devices, such as cloud devices in over-the-top (OTT) systems.

[0220] In the research of 5.5-generation (5.5G) and future mobile networks, the integration of communication and sensing (also known as sensing) is an important technological direction. Communication systems possess sensing capabilities, enabling integrated design of communication and sensing. Similar to Long Term Evolution (LTE) / New Radio (NR) communication systems, sensing does not require a separate sensing network or customized terminals, resulting in low deployment, usage, and maintenance costs. Sensing functionality relies on network and terminal capabilities, continuously iterating and evolving.

[0221] The integration of communication and sensing takes many forms, such as using communication signals to perform sensing functions or using sensing results to assist communication. Sensing functions include target detection and target tracking. Sensing targets (also called the sensed targets) include unmanned aerial vehicles (UAVs), human targets, automotive vehicles, automated guided vehicles, and objects creating hazards on roads / railways.

[0222] One sensing method is the single CSI-RS method. As shown in Figure 2, a schematic diagram of a single-antenna receiving model can be used as the sensing signal to detect target motion. The sensing transmitter (Tx) sends CSI-RS signals, and the sensing receiver (Rx) receives the CSI-RS signals sent by the sensing transmitter, or signals reflected or scattered by the target. The signal received by the sensing receiver is the sum of the CSI-RS signal received directly at the sensing receiver without target reflection, and the CSI-RS signal received at the sensing receiver after target reflection.

[0223] As the target moves further away from the Tx side (or Rx side), the amplitude of the received signal fluctuates. Target motion can be sensed by the amplitude of the received signal, and the speed of the target motion can also be sensed by the frequency of the changes in the received signal amplitude.

[0224] Similarly, as the target moves away from the Tx side (or Rx side), the phase of the received signal fluctuates. Target motion can be sensed by the phase of the received signal, and the speed of the target motion can also be sensed by the frequency of the phase changes in the received signal.

[0225] This method can sense target motion based on a single carrier f1 and a single receiver Rx. For example, it can sense target motion by detecting the amplitude and / or phase of the received signal. Another example is to sense the speed of the target motion by detecting the frequency of changes in the amplitude and / or phase of the received signal.

[0226] Because it's necessary to sense changes in the target over time, CSI-RS signals need to be sent periodically. The movement of the target, or its speed, is determined by comparing changes in the sensed signals over a period of time. Specifically, in a single CSI-RS method, the speed of the target's movement can be sensed by the frequency of amplitude and / or phase changes in the received signal within a time period Tw. For example, in respiratory sensing, the speed of the target's movement corresponds to the number of breaths per second.

[0227] However, after the accumulation period Tw, the single CSI-RS method is affected by the time-varying channel caused by Doppler. Taking respiratory sensing as an example, the velocity of chest cavity movement is v = 2D. b • bpm / 60, where D b bpm represents the distance the chest cavity moves during inhalation or exhalation, and bpm represents the number of breaths per minute. The Doppler shift caused by chest cavity movement is fm. d = v·f1 / c, where f1 is the carrier frequency of the sensed signal. The coherence time is T = 1 / f d =30c / D b ·bpm·f. With D b Taking 1cm, bpm=30 as an example, v=0.01m / s, f1=6GHz as an example, the Doppler frequency shift f d =20Hz, coherence time T=5s. That is to say, when the time period Tw exceeds 5s, the sensing results will be affected by the time-varying channel.

[0228] The sensing signals are transmitted periodically. If there is a radio frequency (RF) interruption between any two sensing signal transmissions, a time-varying random phase will be superimposed on the sensing signals. This will cause the amplitude and / or phase variations of the received sensing signal within the time period Tw to be affected by the random phase, and the amplitude and / or phase variations will no longer reflect the target's velocity. For example, in respiratory sensing, due to the influence of the random phase, the amplitude and / or phase variations of the received sensing signal within the time period Tw will no longer reflect the target's respiratory rate (bpm).

[0229] Another sensing method is the CSI-RS quotient method. Figure 3 shows a schematic diagram of a dual-antenna receiving model. In the CSI-RS quotient method, CSI-RS is still used as the sensing signal to detect the target's motion. Compared to the single CSI-RS method, a receiving end for the sensing signal is added. Taking two receiving ends as an example, the transmitting end (Tx) sends CSI-RS signals, and receiving end 1 (Rx1) and receiving end 2 (Rx2) receive the CSI-RS signals sent by Tx, or receive signals reflected or scattered by the target. Specifically, the signal received by Rx1 is the sum of the signal directly received by the CSI-RS on the Rx1 side without target reflection and the signal received by the CSI-RS on the Rx1 side after target reflection; the signal received by Rx2 is the sum of the signal directly received by the CSI-RS on the Rx2 side without target reflection and the signal received by the CSI-RS on the Rx2 side after target reflection. Then, the quotient of the signals received by Rx1 and Rx2 is constructed.

[0230] It can be seen that the amplitude of the received signal quotient fluctuates as the target moves away from the Tx side (or Rx side). Target motion can be sensed by the amplitude of the received signal, and the speed of the target motion can also be sensed by the frequency of the changes in the received signal amplitude.

[0231] Similarly, as the target moves further away from the Tx side (or Rx side), the phase of the received signal fluctuates. Target motion can be sensed by the phase of the received signal, and the speed of the target motion can also be sensed by the frequency of the phase changes in the received signal.

[0232] This method is based on a single carrier f1 and dual receivers Rx to sense target motion. For example, target motion can be sensed by the amplitude and / or phase of the quotient of the signals received from Rx1 and Rx2. As another example, the speed of the target motion can be sensed by the frequency of amplitude and / or phase changes of the quotient of the signals received from Rx1 and Rx2.

[0233] The CSI-RS quotient method described above can overcome the problems of time-varying channels and random phase caused by Doppler. However, the CSI-RS quotient method requires two Rx terminals, therefore two receiving channels are needed to receive the sensed signal in order to use the CSI-RS quotient method. In other words, devices with only one receiving channel cannot use the CSI-RS quotient method.

[0234] Therefore, overcoming the Doppler effect while accurately perceiving the target with relatively low hardware costs is an urgent problem to be solved.

[0235] In view of this, this application provides a sensing scheme in which a sensing transmitter sends a sensing signal to a sensing receiver on a first resource set. The sensing signal includes a first sub-signal and a second sub-signal, which are carried on different resources respectively. This allows the sensing receiver to determine the information of the sensing target based on the information of the first and second sub-signals, such as at least one of conjugate multiplication, amplitude division, and phase subtraction, thereby eliminating the need for multiple sensing receivers and reducing hardware costs. Furthermore, determining the information of the sensing target based on the first and second sub-signals overcomes the problems of time-varying channels and random phases caused by Doppler, thus improving the accuracy of sensing.

[0236] As shown in Figure 4, there are six sensing modes. In the following description, network devices can be understood as TRPs (e.g., base stations), and terminal devices can be understood as UEs.

[0237] The six modes are:

[0238] (1) Network device-to-network device dual station, as shown in Figure 4(a), one network device (network device A) sends a sensing signal and another network device (network device B) receives the sensing signal.

[0239] (2) A single network device station, as shown in Figure 4(b), sends and receives sensing signals.

[0240] (3) Dual-station network device-terminal device, as shown in Figure 4(c), the network device sends sensing signals and the terminal device receives sensing signals.

[0241] (4) Dual station of terminal device and network device, as shown in Figure 4(d), the terminal device sends sensing signals and the network device receives sensing signals.

[0242] (5) Terminal device-terminal device dual station, as shown in Figure 4(e), one terminal device (terminal device A) sends a sensing signal and the other terminal device (terminal device B) receives the sensing signal.

[0243] (6) Single terminal equipment station, as shown in Figure 4(f), the same terminal equipment sends and receives sensing signals.

[0244] The following terms may be used in the embodiments of this application:

[0245] Sensing signal: A signal transmitted over the air interface that can be used to sense the destination; it can also be called a sensing reference signal. Sensing services can be implemented by processing the sensing signal.

[0246] Sensing transmitter: A network device or terminal device that sends sensing signals. The sensing transmitter can be located in the same network device or terminal device as the sensing receiver; or it can be located in a different network device or terminal device than the sensing receiver.

[0247] Sensing receiver: A network device or terminal device that receives sensing signals. The sensing receiver can be located in the same network device or terminal device as the sensing transmitter; alternatively, it can be located in a different network device or terminal device.

[0248] Sensing target: also known as the perceived target, target, etc. The characteristics of the target are derived based on the sensed signals.

[0249] Mono-static sensing: The sensing transmitter that sends sensing signals and the sensing receiver that receives sensing signals are located in the same network device or terminal device.

[0250] Bi-static sensing: The sensing transmitter that sends sensing signals and the sensing receiver that receives sensing signals are not in the same network device or terminal device.

[0251] Figure 5 shows a flowchart of a sensing method provided in an embodiment of this application. Exemplarily, the method may include the following steps:

[0252] S501. Send a second sensing signal on the first resource set.

[0253] Step S501 can be performed by the sensing transmitter or by its modules (e.g., processor, chip, chip system, circuit, etc.).

[0254] Accordingly, a first sensing signal is received from the first resource set. This reception can be performed by a sensing receiver or by a module therein (e.g., a processor, chip, chip system, circuit, etc.).

[0255] For example, the sensing transmitter can be a network device or a terminal device, and the sensing receiver can be a network device or a terminal device. This embodiment can be applied to any of the above six sensing modes. For example, when this embodiment is applied to the above-mentioned sensing mode (1), both the sensing transmitter and the sensing receiver can be network devices (e.g., network device A and network device B, respectively); when this embodiment is applied to the above-mentioned sensing mode (2), the sensing transmitter and the sensing receiver are the same network device; when this embodiment is applied to the above-mentioned sensing mode (3), the sensing transmitter is a network device and the sensing receiver is a terminal device; when this embodiment is applied to the above-mentioned sensing mode (4), the sensing transmitter is a terminal device and the sensing receiver is a network device; when this embodiment is applied to the above-mentioned sensing mode (5), both the sensing transmitter and the sensing receiver can be terminal devices (e.g., terminal device A and terminal device B, respectively); when this embodiment is applied to the above-mentioned sensing mode (6), the sensing transmitter and the sensing receiver are the same terminal device.

[0256] In this context, "sensing" refers to the signal propagating via a path that can be "sensing transmitter - sensing target - sensing receiver," "sensing transmitter - sensing receiver," or "sensing transmitter - interference / environment - sensing receiver." In other words, the sensing signal can be a single path or a combination of these paths. The sensing receiver receives the sum of these paths. Therefore, regarding the first and second sensing signals, the second sensing signal is transmitted by the sensing transmitter, reflected or scattered by the sensing target, and ultimately received by the sensing receiver is the first sensing signal. Changes in the first sensing signal compared to the second sensing signal include changes caused by reflection or scattering from the sensing target, such as changes in the time and / or frequency domains, and changes in amplitude and / or phase. These changes reflect, to some extent, the information of the sensing target.

[0257] Therefore, it can be considered that: the first sensing signal includes the signal received after the second sensing signal is reflected or scattered by the sensing target; further, the first sensing signal may also include the second sensing signal received directly by the sensing receiver from the sensing transmitter; or, the first sensing signal is the signal received after the second sensing signal is reflected or scattered by the sensing target, that is, the first sensing signal may not include other signals; or, the first sensing signal is the second sensing signal, that is, although the second sensing signal is reflected or scattered by the sensing target, the information carried by the first sensing signal and the second sensing signal is still considered unchanged; or, the first sensing signal includes the second sensing signal, and further, the first sensing signal may also include other signals.

[0258] The first sensing signal comprises two components, or two parts, namely a first sub-signal and a second sub-signal. Exemplarily, the first and second sub-signals are generated from the same sequence, which is the same sequence that generates the first sensing signal. That is, the first and second sub-signals belong to the same signal. Alternatively, the first and second sub-signals are independent signals, for example, they are generated from different sequences. Exemplarily, the first and second sub-signals may contain the same frequency; they may contain different frequencies; or they may contain partially the same frequency and partially different frequencies. The different frequencies may be different resource elements (REs), different resource blocks (RBs), or different subcarriers.

[0259] For example, consider a first sensing signal comprising four frequencies corresponding to RE1, RE2, RE3, and RE4. The frequencies corresponding to the first and second sub-signals can be interleaved. For instance, the first sub-signal may include the frequencies corresponding to RE1 and RE3, and the second sub-signal may include the frequencies corresponding to RE2 and RE4. Alternatively, the first and second sub-signals can be continuously distributed. For instance, the first sub-signal may include the frequencies corresponding to RE1 and RE2, and the second sub-signal may include the frequencies corresponding to RE3 and RE4. Furthermore, the first and second sub-signals can partially overlap. For instance, the first sub-signal may include the frequencies corresponding to RE1, RE2, and RE3, and the second sub-signal may include the frequencies corresponding to RE2, RE3, and RE4.

[0260] The second sensing signal comprises two components, or two parts, namely a third sub-signal and a fourth sub-signal. Exemplarily, the third and fourth sub-signals are generated from the same sequence, which is the same sequence that generates the second sensing signal. That is, the third and fourth sub-signals belong to the same signal. Alternatively, the third and fourth sub-signals are independent signals, for example, they are generated from different sequences. Exemplarily, the third and fourth sub-signals may contain the same frequency; they may contain different frequencies; or they may contain partially the same frequency and partially different frequencies. The different frequencies may be different REs, different RBs, or different subcarriers.

[0261] For example, the second sensing signal includes four frequencies corresponding to RE1, RE2, RE3, and RE4. The frequencies corresponding to the third and fourth sub-signals can be interleaved. For example, the third sub-signal includes the frequencies corresponding to RE1 and RE3, and the fourth sub-signal includes the frequencies corresponding to RE2 and RE4. The third and fourth sub-signals can also be continuously distributed. For example, the third sub-signal includes the frequencies corresponding to RE1 and RE2, and the fourth sub-signal includes the frequencies corresponding to RE3 and RE4. The third and fourth sub-signals can also partially overlap. For example, the third sub-signal includes the frequencies corresponding to RE1, RE2, and RE3, and the fourth sub-signal includes the frequencies corresponding to RE2, RE3, and RE4.

[0262] In other words, the receiving end's reception of the first sensing signal can also be understood as receiving the first and second sub-signals; similarly, the sending end's transmission of the second sensing signal can also be understood as transmitting the third and fourth sub-signals. The third sub-signal transmitted by the sending end arrives at the receiving end via a different transmission path, and the signal received by the receiving end is the first sub-signal; similarly, the fourth sub-signal transmitted by the sending end arrives at the receiving end via a different transmission path, and the signal received by the receiving end is the second sub-signal.

[0263] Therefore, it can be considered that: the first sub-signal includes the signal received after the third sub-signal is reflected or scattered by the sensing target; further, the first sub-signal may also include the third sub-signal directly received by the sensing receiver from the sensing transmitter; or, the first sub-signal is the signal received after the third sub-signal is reflected or scattered by the sensing target, that is, the first sub-signal may not include other signals; or, the first sub-signal is the third sub-signal, that is, although the third sub-signal is reflected or scattered by the sensing target, the information carried by the first sub-signal and the third sub-signal is still considered unchanged; or, the first sub-signal includes the third sub-signal, and further, the first sub-signal may also include other signals.

[0264] Similarly, it can be considered that: the second sub-signal includes the signal received after the fourth sub-signal is reflected or scattered by the sensing target; further, the second sub-signal may also include the fourth sub-signal directly received by the sensing receiver from the sensing transmitter; or, the second sub-signal is the signal received after the fourth sub-signal is reflected or scattered by the sensing target, that is, the second sub-signal may not include other signals; or, the second sub-signal is the fourth sub-signal, that is, although the fourth sub-signal is reflected or scattered by the sensing target, the information carried by the second sub-signal and the fourth sub-signal is still considered unchanged; or, the second sub-signal includes the fourth sub-signal, and further, the second sub-signal may also include other signals.

[0265] For example, consider the first sensing signal and the second sensing signal, which include four frequencies corresponding to RE1, RE2, RE3, and RE4. The frequencies corresponding to the first and second sub-signals are interleaved; that is, the frequencies corresponding to the third and fourth sub-signals can also be interleaved. For example, the first and third sub-signals include the frequencies corresponding to RE1 and RE3, and the second and fourth sub-signals include the frequencies corresponding to RE2 and RE4. Alternatively, the first and second sub-signals can be continuously distributed, meaning the third and fourth sub-signals can also be continuously distributed. For example, the first and third sub-signals include the frequencies corresponding to RE1 and RE2, and the second and fourth sub-signals include the frequencies corresponding to RE3 and RE4. Furthermore, the first and second sub-signals can partially overlap, meaning the third and fourth sub-signals can also partially overlap. For example, the first and third sub-signals include the frequencies corresponding to RE1, RE2, and RE3, and the second and fourth sub-signals include the frequencies corresponding to RE2, RE3, and RE4.

[0266] The sensing signal in this embodiment can also be referred to as a signal acting on sensing, a sensing reference signal, or a reference signal used for sensing. The sensing signal can be a signal transmitted separately; it can also be a signal transmitted together with a communication signal; or it can be a communication signal used for sensing services.

[0267] Exemplarily, the sensing signal in this embodiment can be any one of the following: channel state information-reference signal (CSI-RS), synchronization signal block (SSB), positioning reference signal (PRS), and sounding reference signal (SRS). The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS. In this embodiment, both the first sensing signal and the second sensing signal are referred to as sensing signals, and the first sub-signal, second sub-signal, third sub-signal, and fourth sub-signal can also be referred to as sensing signals. These signals are all signals that can determine information about the sensing target. It is understood that the first sensing signal including the first and second sub-signals, and the second sensing signal including the third and fourth sub-signals, are merely examples; the first and second sensing signals can include more sub-signals. Implementations of the first and second sensing signals including more sub-signals can refer to this embodiment.

[0268] For example, the first and second sub-signals described above have a quasi-co-location (QCL) relationship. Similarly, the third and fourth sub-signals described above have a quasi-co-location relationship.

[0269] The first resource set includes a first resource and a second resource. The first resource carries a first sub-signal and / or a third sub-signal, and the second resource carries a second sub-signal and / or a fourth sub-signal. For example, the first resource and the second resource may contain the same frequency resource; they may be different frequency resources; or they may be partially the same frequency resource and partially different frequency resources.

[0270] In one example, the first and second resources have the same time domain but different frequency domains; that is, the first and second sub-signals are carried on the same time unit but different frequency units. For example, the first and second sub-signals are carried on different REs of the same symbol, and the frequency domain interval between the first and second sub-signals is Δf. For example, the first sub-signal is transmitted on the RE corresponding to f1, and the second sub-signal is transmitted on the RE corresponding to f2. The first sub-signal can be expressed as exp(2jπf1t), and the second sub-signal can be expressed as exp(2jπf2t). Here, f1 and f2 represent that the first and second sub-signals are carried on different frequency domain resources, and |f1-f2| is the frequency difference between the first and second sub-signals. Exemplarily, the frequency domain interval between the first and second resources is less than or equal to a first threshold, so that |f1-f2| is as small as possible to reduce the impact of time-varying channels.

[0271] In another example, the first and second resources have different time and frequency domains, meaning the first and second sub-signals are carried on different time units and different frequency units. For example, if the first and second sub-signals are carried on M1 REs and M2 symbols, then the first and second sub-signals are carried on the first resource set (M = M1 * M2) consisting of M1 REs and M2 symbols.

[0272] In the above example, the time unit can be a system frame, subframe, time slot, micro-time slot, orthogonal frequency division multiplexing (OFDM) symbol, etc. The frequency unit can be a subcarrier, RB, RE, control channel element (CCE), etc.

[0273] Optionally, the frequency domain resources of the first resource include M A The frequency domain resources of the first frequency unit and / or the second resource include M B A second frequency unit. Exemplarily, in this embodiment, M A =M B Among them, M A The value is an integer greater than or equal to 1. That is, the first resource and the second resource can each include multiple frequency units, and the first resource and the second resource contain different frequency units or partially different frequency units. The frequency domain resources of the first resource set include M frequency units, and the number of first frequency units included in the first resource and the number of second frequency units included in the frequency domain resources of the second resource are equal. It can be understood that M of these M frequency units... A The frequency domain resources of the first resource are M frequency units. AThe first frequency unit. M of these M frequency units. A Each frequency unit is a frequency domain resource of the second resource, namely M. A There is a second frequency unit. The first frequency unit can be any one of subcarrier, RB, RE, CCE, etc. The second frequency unit can also be any one of subcarrier, RB, RE, CCE, etc. For example, both the first and second frequency units can be REs.

[0274] The relationship between the first resource and the second resource satisfies any of the following conditions: M of the first resource A M of the first frequency unit and the second resource A The second frequency units can be staggered; or, the M of the first resource... A M of the first frequency unit and the second resource A The second frequency units can also be continuously distributed; or, the M of the first resource... A M of the first frequency unit and the second resource A The second frequency units can also partially overlap. That is, in the first resource set, a certain frequency unit can belong to both the first frequency unit and the second frequency unit; or, in the first resource set, a certain frequency unit can belong to both the first frequency unit and the second frequency unit.

[0275] The frequency domain spacing between the first frequency unit and the second frequency unit can be less than or equal to a second threshold. Alternatively, the frequency domain spacing between the m-th first frequency unit included in the first resource and the m-th second frequency unit included in the second resource can be less than or equal to the second threshold. Where m is greater than or equal to 1 and less than or equal to M. A The integer is used to ensure that the frequency units in the first and second resources have the smallest possible frequency domain difference, thereby reducing the impact of time-varying channels.

[0276] The frequency domain spacing between the first frequency unit and the second frequency unit can be greater than or equal to a third threshold. Alternatively, the frequency domain spacing between the m-th first frequency unit included in the first resource and the m-th second frequency unit included in the second resource can be greater than or equal to the third threshold. Where m is greater than or equal to 1 and less than or equal to M. A The frequency difference between the frequency units in the first and second resources must not be too small; otherwise, the first and second sub-signals will carry information about overly similar sensing targets. In extreme cases, if the frequency difference is zero, it is equivalent to the first and second sub-signals carrying the same information about the same sensing target, and their combined information will not have any additional incremental information.

[0277] For example, taking the first sensing signal and / or the second sensing signal as including four frequency units RE1, RE2, RE3, and RE4, the indices of these four frequency units are in ascending or descending order. The relationship between the frequency units in the first resource and the frequency units in the second resource satisfies any of the following:

[0278] a) M, the first resource A M of the first frequency unit and the second resource A The second frequency units can be staggered.

[0279] In other words, each first frequency unit of the first resource and each second frequency unit of the second resource are interleaved.

[0280] For example, the first resource includes first frequency units RE1 and RE3, and the second resource includes second frequency units RE2 and RE4. The first sub-signal is the sensing signal carried on RE1 and RE3, the second sub-signal is the sensing signal carried on RE2 and RE4, the third sub-signal is the sensing signal carried on RE1 and RE3, and the fourth sub-signal is the sensing signal carried on RE2 and RE4.

[0281] For example, the frequency domain interval between the first frequency unit RE1 and the second frequency unit RE2 is less than or equal to the second threshold. The frequency domain interval between the first frequency unit RE3 and the second frequency unit RE4 is less than or equal to the second threshold.

[0282] For example, the frequency domain interval between the first frequency unit RE1 and the second frequency unit RE2 is greater than or equal to the third threshold. The frequency domain interval between the first frequency unit RE3 and the second frequency unit RE4 is greater than or equal to the third threshold.

[0283] b) M of the first resource A M of the first frequency unit and the second resource A The second frequency units can also be distributed continuously.

[0284] For example, the first resource includes first frequency units RE1 and RE2, and the second resource includes second frequency units RE3 and RE4. The first sub-signal is the sensing signal carried on RE1 and RE2, the second sub-signal is the sensing signal carried on RE3 and RE4, the third sub-signal is the sensing signal carried on RE1 and RE2, and the fourth sub-signal is the sensing signal carried on RE3 and RE4.

[0285] For example, the frequency domain interval between the first frequency unit RE1 and the second frequency unit RE3 is less than or equal to the second threshold. The frequency domain interval between the first frequency unit RE2 and the second frequency unit RE4 is less than or equal to the second threshold.

[0286] For example, the frequency domain interval between the first frequency unit RE1 and the second frequency unit RE3 is greater than or equal to the third threshold. The frequency domain interval between the first frequency unit RE2 and the second frequency unit RE4 is greater than or equal to the third threshold.

[0287] c) M of the first resource A M of the first frequency unit and the second resource A The second frequency units can also partially overlap.

[0288] For example, the first resource includes first frequency units RE1, RE2, and RE3, and the second resource includes second frequency units RE2, RE3, and RE4. The first sub-signal is the sensing signal carried on RE1, RE2, and RE3; the second sub-signal is the sensing signal carried on RE2, RE3, and RE4; the third sub-signal is the sensing signal carried on RE1, RE2, and RE3; and the fourth sub-signal is the sensing signal carried on RE2, RE3, and RE4.

[0289] For example, the frequency domain interval between the first frequency unit RE1 and the second frequency unit RE2 is less than or equal to the second threshold. The frequency domain interval between the first frequency unit RE2 and the second frequency unit RE3 is less than or equal to the second threshold. The frequency domain interval between the first frequency unit RE3 and the second frequency unit RE4 is less than or equal to the second threshold.

[0290] For example, the frequency domain interval between the first frequency unit RE1 and the second frequency unit RE2 is greater than or equal to the third threshold. The frequency domain interval between the first frequency unit RE2 and the second frequency unit RE3 is greater than or equal to the third threshold. The frequency domain interval between the first frequency unit RE3 and the second frequency unit RE4 is greater than or equal to the third threshold.

[0291] The frequency of the sensing signal can be determined through the following implementation: The sensing signal can be a first sensing signal and / or a second sensing signal. That is, the frequency resources of the first resource set are determined through the following implementation. Alternatively, the sensing signal can also be at least one of a first sub-signal, a second sub-signal, a third sub-signal, and / or a fourth sub-signal. That is, the frequency resources of the first resource and / or the second resource are determined through the following implementation.

[0292] In one implementation, the first sensing signal and / or the second sensing signal are located in the first and / or second portions of the bandwidth part (BWP) at the sensing transmitter. The first portion of the bandwidth includes resource blocks whose index is less than or equal to a first value, and the second portion of the bandwidth includes resource blocks whose index is greater than or equal to a second value. For example, the first portion carries a first sub-signal, and the second portion carries a second sub-signal; and / or, the first portion carries a third sub-signal, and the second portion carries a fourth sub-signal. That is, the first resource includes the first portion, and the second resource includes the second portion; or, the first resource is the first portion, and the second resource is the second portion. Here, the BWP can be understood as a BWP used for sensing, or a BWP carrying sensing services.

[0293] In another implementation, the highest RE with the highest RB index and the lowest RE with the lowest RB index in the BWP may carry the first sub-signal and the second sub-signal, respectively; and / or, the highest RE with the highest RB index and the lowest RE with the lowest RB index in the BWP may carry the third sub-signal and the fourth sub-signal, respectively. That is, the first resource includes the highest RE with the highest RB index in the BWP, and the second resource includes the lowest RE with the lowest RB index in the BWP. Alternatively, the highest-indexed RE and the lowest-indexed RE in the BWP may carry the first sub-signal and the second sub-signal, respectively; and / or, the highest-indexed RE and the lowest-indexed RE in the BWP may carry the third sub-signal and the fourth sub-signal, respectively. That is, the first resource includes the highest-indexed RE in the BWP, and the second resource includes the lowest-indexed RE in the BWP. Here, the BWP can be understood as a BWP used for sensing, or a BWP carrying sensing services.

[0294] In another implementation, the first sensing signal and / or the second sensing signal are located in the first and / or second parts of the BWP at the sensing transmitter. The first part of the BWP includes at least one resource block whose index gradually increases from the lowest index, and the second part of the BWP includes at least one resource block whose index gradually decreases from the highest index. For example, the first part carries a first sub-signal, and the second part carries a second sub-signal; and / or, the first part carries a third sub-signal, and the second part carries a fourth sub-signal. That is, the first resource includes the first part, and the second resource includes the second part; or, the first resource is the first part, and the second resource is the second part. Here, the BWP can be understood as a BWP used for sensing, or a BWP carrying sensing services.

[0295] Sensing signals are transmitted on both sides of a portion of the bandwidth, while communication signals can be transmitted within a continuous frequency domain unit of that portion of the bandwidth. This facilitates resource allocation for communication signals and reduces the impact of sensing on communication.

[0296] In another implementation, the frequency resources of the sensed signal are associated with at least one of the following parameters: the number of frequency units included in the sensed signal, a first frequency difference, a second frequency difference, a sense bandwidth, a first frequency offset, and a second frequency offset. The number of frequency units included in the sensed signal can be understood as the number M of frequency units included in the first resource set, or as the number M of frequency units included in the first resource and / or the second resource. A The first frequency difference Δf is the frequency difference between any two frequency elements in the M frequency elements; the second frequency difference Δf A It is M A The frequency difference between any two first frequency units in each first frequency unit, and / or, is M. A The frequency difference between every two second frequency units in a second frequency unit; the sensing bandwidth is the bandwidth used for sensing, or the bandwidth carrying sensing services; the first frequency offset is the first frequency offset of the lowest RE of the sensing signal relative to the lowest RE of the BWP, or the first frequency offset of the lowest RB of the sensing signal relative to the lowest RB of the BWP; the second frequency offset Δf 1,2 It is the frequency difference between the frequency unit with the smallest index in the first resource and the frequency unit with the smallest index in the second resource, or it is the frequency difference between the frequency unit with the largest index in the first resource and the frequency unit with the largest index in the second resource.

[0297] The following description assumes the following parameters as an example to illustrate how to determine the frequency resources carrying the first sensing signal and / or the second sensing signal, i.e., how to determine the frequency resources of the first resource set: the number of frequency units is M, the first frequency difference is Δf, and the sensing bandwidth is BW. S The first frequency offset is fo. That is, M is the number of frequency units included in the first resource set, or it can be the number of frequency units carrying the first sensing signal and / or the second sensing signal; the first frequency difference Δf is the frequency difference between every two frequency units in the M frequency units.

[0298] In one example, the frequencies of the first sensing signal and / or the second sensing signal can be determined based on the number of frequency units M and the first frequency difference Δf (determining the frequency resources of the first resource set):

[0299] The first sensing signal and / or the second sensing signal includes frequency units with a frequency of (m-1)·Δf, where m = 1, 2, ..., M. For example, the first sensing signal and / or the second sensing signal includes frequency units with indices {0, Δf, 2Δf, ..., (M-1)·Δf}.

[0300] In other words, the m-th frequency unit in the first resource set is (m-1)·Δf, where m = 1, 2, ..., M. For example, the first resource set includes frequency units with indices {0, Δf, 2Δf, ..., (M-1)·Δf}.

[0301] In this example, the first sub-signal, the second sub-signal, the third sub-signal, and / or the fourth sub-signal are determined using any one of case 1), case 2), or case 3). That is, the frequency resources of the first resource and / or the second resource are determined using any one of case 1), case 2), or case 3).

[0302] Case 1):

[0303] The first and / or third sub-signal is carried by a frequency unit with a frequency of 2(m1-1)·Δf, where m1 = 1, 2, ..., M / 2. For example, the first and / or third sub-signal is carried by a frequency unit with the index {0, 2Δf, 4Δf, ..., (M-2)·Δf}. The second and / or fourth sub-signal is carried by a frequency unit with a frequency of (2m1-1)·Δf, where m1 = 1, 2, ..., M / 2. For example, the second and / or fourth sub-signal is carried by a frequency unit with the index {Δf, 3Δf, 5Δf, ..., (M-1)·Δf}.

[0304] That is, the m1-th frequency unit in the first resource is 2(m1-1)·Δf, where m1 = 1, 2, ..., M / 2; the m1-th frequency unit in the second resource is (2m1-1)·Δf, where m1 = 1, 2, ..., M / 2. For example, the first resource includes frequency units with indices {0, 2Δf, 4Δf, ..., (M-2)·Δf}, and the second resource includes frequency units with indices {Δf, 3Δf, 5Δf, ..., (M-1)·Δf}.

[0305] In case 1, the first resource M A M of the first frequency unit and the second resource A The second frequency units are interleaved, where M A =M / 2.

[0306] Situation 2):

[0307] The first and / or third sub-signal is carried by a frequency unit with a frequency of (m1-1)·Δf, where m1 = 1, 2, ..., M / 2. For example, the first and / or third sub-signal is carried by a frequency unit with an index of {0,Δf, 2Δf, ..., (M-2)·Δf / 2}. The second and / or fourth sub-signal is carried by a frequency unit with a frequency of (M+2m1-1)·Δf / 2, where m1 = 1, 2, ..., M / 2.

[0466] The "good" channel quality measurement result includes at least one of the following: a channel quality indication (CQI) greater than or equal to a first CQI threshold, a signal-to-noise ratio (SNR) less than or equal to a first SNR threshold, a signal-to-interference plus noise ratio (SINR) less than or equal to a first SINR threshold, and a channel busy ratio (CBR) less than or equal to a first CBR threshold.

[0467] Another approach is to determine the number M of frequency units in the first resource set, and the number M of frequency units in the first resource and / or the second resource, based on the energy of the sensed signal.

[0474] Optionally, the lower the energy of the sensed signal, the smaller Δf 1,2 The smaller the value, and / or the higher the energy of the sensed signal, the better. 1,2 The larger the value.

[0475] The sensing signal can be a first sensing signal and / or a second sensing signal, or it can be a first sub-signal, a second sub-signal, a third sub-signal and / or a fourth sub-signal.

[0476] The low energy of the sensed signal includes: the RSSI of the sensed signal being less than or equal to a first RSSI threshold, the RSRP of the sensed signal being less than or equal to a first RSSI threshold, and the power backoff value of the sensed signal being greater than or equal to a first power backoff threshold. Similarly, the high energy of the sensed signal includes: the RSSI of the sensed signal being greater than or equal to a first RSSI threshold, the RSRP of the sensed signal being greater than or equal to a first RSSI threshold, and the power backoff value of the sensed signal being less than or equal to a first power backoff threshold.

[0477] Wherein, the first sensing signal and the second sensing signal are used to determine information about the sensing target; or, the first sensing signal and the second sensing signal are used to determine at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, velocity information of the sensing target, and angle information of the sensing target. Similarly, the first sub-signal, the second sub-signal, the third sub-signal, and / or the fourth sub-signal are used to determine information about the sensing target; or, the first sub-signal, the second sub-signal, the third sub-signal, and / or the fourth sub-signal are used to determine information about the sensing target; or, the first sub-signal, the second sub-signal, the third sub-signal, and / or the fourth sub-signal are used to determine at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, velocity information of the sensing target, and angle information of the sensing target.

[0478] In this invention, the first sensing signal and / or the second sensing signal are periodically transmitted signals. The period of the first sensing signal can be understood as the time interval of the first sensing signal, and similarly, the period of the second sensing signal can be understood as the time interval of the second sensing signal. In this invention, the period of the first sensing signal and / or the period of the second sensing signal can be simply referred to as the period of the sensing signal, denoted as P. Exemplarily, the period of the sensing signal is associated with information of the sensing service. The information of the sensing service includes at least one of the following: sensing speed accuracy, sensing speed resolution, sensing distance accuracy, sensing distance resolution, maximum sensing speed, and maximum sensing distance.

[0479] For example, the sensing transmitter can transmit Y second sensing signals over Y first time units, and correspondingly, the sensing receiver can receive Y first sensing signals over Y first time units. The time domain range of these Y first time units can be regarded as a sensing window; that is, the Y first time units can also be understood as a sensing window. In other words, information about the sensing target is determined based on the first sensing signals and / or second sensing signals accumulated within the sensing window.

[0480] In this embodiment, the first time unit can be a symbol or a time slot, such as a sensing symbol or a sensing time slot.

[0481] For example, the first resource has the same frequency resources across Y first time units; and / or, for example, the second resource has the same frequency resources across Y first time units. That is, in each of the Y first time units, the first resource is the same frequency domain resource; and / or, in each of the Y first time units, the second resource is the same frequency domain resource. This is because the channel has frequency-selective fading, and using the same frequency domain resources ensures that the frequency-selective fading is as similar as possible across the Y first time units, thereby increasing the reliability of sensing.

[0482] The first sub-signal and / or the third sub-signal are mapped onto the first resource. That is, in each of the Y first time units, the first sub-signal is mapped onto the same frequency domain resource. In each of the Y first time units, the third sub-signal is mapped onto the same frequency domain resource.

[0483] The second sub-signal and / or the fourth sub-signal are mapped onto the first resource. That is, in each of the Y first time units, the second sub-signal is mapped onto the same frequency domain resource. Similarly, in each of the Y first time units, the fourth sub-signal is mapped onto the same frequency domain resource.

[0484] The period of the first sensing signal can be determined based on the sensing window and / or the number of first sensing signals within the sensing window. The duration Tw of the sensing window is determined by the sensing speed resolution and / or sensing distance resolution. The number of first sensing signals within the sensing window is determined by the maximum sensing speed and / or the maximum sensing distance, or the period of the sensing signal is determined by the maximum sensing speed and / or the maximum sensing distance.

[0485] In this embodiment, the velocity resolution v res It is based on the perceived target's movement distance D b The duration Tw of the perception window is determined by the velocity resolution v. res , the perceived target's movement distance D bThe duration Tw of the perception window satisfies the following relationship: v res =2D b / T w For example, in respiratory perception, D b This represents the distance the chest cavity moves during inhalation or exhalation. (D) b Taking 1cm as an example, the duration T of the sensing window w =60s, then the velocity resolution v res The value is 0.0003 m / s; correspondingly, if a velocity resolution v is achieved... res =0.0003m / s, then the duration T of the sensing window w Requires T w =60s. Other examples can be found in Table 1.

[0486] Table 1 Velocity resolution v res Determined example

[0487] For example, in respiratory sensing, it is necessary to sense the number of breaths per minute (bpm) of the target. The period of the first sensing signal and / or the second sensing signal can be determined based on the respiratory rate resolution and / or the maximum respiratory rate. The duration Tw of the sensing window can be determined based on the respiratory rate resolution (Δbpm) and / or the maximum respiratory rate (Max). bpm This is correct. This is because, in respiratory perception, velocity resolution can be understood as respiratory rate resolution, such as the resolution of breaths per second or breaths per minute. In respiratory perception, maximum velocity can be understood as the maximum number of breaths, such as the maximum number of breaths per second or the maximum number of breaths per minute.

[0488] For example, in respiratory perception, the respiratory rate resolution Δbpm is based on the velocity resolution v. res Definitely. Breath rate resolution Δbpm and velocity resolution v. res Satisfying relation: v res =D b ·Δbpm / 30, that is, Δbpm=30v res / D b With D b Taking Δbpm = 1 as an example, when Δbpm = 1, the corresponding v res ≈0.0003m / s; correspondingly, v res When the velocity is 0.0003 m / s, the corresponding Δbpm ≈ 1. Other examples can be found in Table 2.

[0489] Table 2. Respiratory rate resolution Δbpm and velocity resolution v in respiratory perception. res Relationship Example

[0490] An example in the perception of breath:

[0491] The relationship between respiratory rate resolution and the duration of the perception window (Tw) is: Δbpm = 60 / Tw. For example, if a resolution of Δbpm ≤ 1 is required, a time-domain window with Tw ≥ 60 s is needed. Similarly, if a resolution of Δbpm ≤ 2 is required, a time-domain window with Tw ≥ 30 s is needed. And if a resolution of Δbpm ≤ 3 is required, a time-domain window with Tw ≥ 20 s is needed. Other examples can be found in Table 1.

[0492] Maximum number of breaths bpm The duration of the perception window (Tw) and the number of first-time units (Y) satisfy the following relationship: Max bpm = 60*Y / 2*Tw. For example, if you need to perceive Max... bpm For a case where Tw = 60, then within a perception window of 60s, Y ≥ 120 cycles of sensing signal are required. For example, if it is necessary to sense Max... bpm For the use case where Tw = 30, then within a perception window of Tw = 60s, Y ≥ 60 cycles of sensing signal are required. Other examples can be found in Table 1.

[0493] The period P of the sensed signal, the duration Tw of the sense window, and the number of first time units Y satisfy the relationship: P = Tw / Y. For example, with Tw = 60s and Y ≥ 120, the period P needs to be ≤ 500ms. Another example is with Tw = 30s and Y ≥ 30, in which case the period P needs to be ≤ 1000ms. Other examples can be found in Table 3.

[0494] Table 3. Examples of determining the number of first time units and / or the period of the sensing signal in respiratory sensing.

[0495] The configuration of the aforementioned sensing signals can be configured in several ways. The sensing signals can be a first sensing signal and / or a second sensing signal, or a first sub-signal, a second sub-signal, a third sub-signal, and / or a fourth sub-signal.

[0496] One configuration method involves the network device sending configuration information for a sensing signal. This configuration information includes at least one of the following pieces of information about a first resource set: the number of frequency elements M in the first resource set, the first frequency difference Δf, and the sensing bandwidth BW. S The first frequency offset fo. Alternatively, the configuration information of the sensing signal includes at least one of the following information about the first resource and / or the second resource: the number M of frequency units included in the first resource and / or the second resource. A First frequency difference Δf, second frequency difference Δf A Perceived bandwidth BW SFirst frequency offset fo, second frequency offset Δf 1,2 .

[0497] It can be the configuration information for the sensing transmitter to send sensing signals, or the configuration information for the sensing receiver to send sensing signals.

[0498] The specific configuration methods for the six different perception modes mentioned above are as follows:

[0499] For example, in a dual-site network device mode, network device A sends configuration information for sensing signals to network device B. Network device A then sends a second sensing signal to network device B, and network device B receives the first sensing signal. Alternatively, network device B sends a second sensing signal to network device A, and network device A receives the first sensing signal.

[0500] For example, in a dual-site mode of network device-terminal device, the network device sends configuration information for sensing signals to the terminal device. The network device sends a second sensing signal to the terminal device, and the terminal device receives the first sensing signal. Alternatively, the terminal device sends a second sensing signal to the network device, and the network device receives the first sensing signal.

[0501] For example, in a dual-site mode of terminal device-network device, the network device sends configuration information for sensing signals to the terminal device. The terminal device sends a second sensing signal to the network device, and the network device receives the first sensing signal. Alternatively, the network device sends a second sensing signal to the terminal device, and the terminal device receives the first sensing signal.

[0502] For example, in a dual-site terminal device mode, the network device sends configuration information for sensing signals to terminal device A and / or terminal device B. Terminal device A sends a second sensing signal to terminal device B, and terminal device B receives the first sensing signal. Alternatively, terminal device B sends a second sensing signal to terminal device A, and terminal device A receives the first sensing signal.

[0503] For example, in a dual-station terminal device mode, terminal device A sends configuration information for sensing signals to terminal device B. Terminal device A then sends a second sensing signal to terminal device B, and terminal device B receives the first sensing signal. Alternatively, terminal device B sends a second sensing signal to terminal device A, and terminal device A receives the first sensing signal.

[0504] For example, in a dual-station terminal device mode, terminal device B sends configuration information for sensing signals to terminal device A. Terminal device A then sends a second sensing signal to terminal device B, and terminal device B receives the first sensing signal. Alternatively, terminal device B sends the second sensing signal to terminal device A, and terminal device A receives the first sensing signal.

[0505] For example, in a single-site terminal device mode, the network device sends configuration information for sensing signals to the terminal device. The terminal device then sends a second sensing signal and receives the first sensing signal. In other words, the terminal device transmits and receives sensing signals independently.

[0506] In this embodiment, the network device can be understood as a TRP (e.g., a base station), and the terminal device can be understood as a UE.

[0507] Another configuration method involves the terminal device sending a sensing request message, and the network device sending configuration information for the sensing signal. For example, the sensing receiver sends a sensing request message to the sensing sender, or the sensing sender sends a sensing request message to the sensing receiver. This sensing request message is used to request the configuration information for the sensing signal.

[0508] After receiving the aforementioned sensing request information, the network device sends sensing response information to the sensing sender and / or sensing receiver. This sensing response information can be configuration information for the sensing signal. The configuration information for the sensing signal can meet the sensing service requirements of the terminal device.

[0509] For example, the sensing receiver is a terminal device, and the sensing transmitter is a network device. The terminal device sends a sensing request message to the network device. Based on the sensing request message from the terminal device, the network device sends configuration information for the sensing signal back to the terminal device.

[0510] For example, the perception request information can be understood as perception business requirement information. For instance, the perception request information (or perception business requirement information) includes at least one of the following: the number M of frequency units included in the first resource set, and the number M of frequency units included in the first resource and / or the second resource. A First frequency difference Δf, second frequency difference Δf A Perceived bandwidth BW S First frequency offset fo, second frequency offset Δf 1,2 .

[0511] For example, the perception request information can also be understood as perception service type information. For instance, the perception request information includes at least one of the following: perception scenario, perception service type, confidence level, accuracy of location estimation, accuracy of speed estimation, distance resolution, speed resolution, maximum distance, maximum speed, maximum perception service latency, refresh rate, missed detection rate, and false alarm rate. The estimation accuracy can include horizontal and / or vertical accuracy. The resolution can include horizontal and / or vertical resolution. For example, in respiratory perception, speed resolution can be understood as respiratory rate resolution, such as the resolution of respiratory rates per second or respiratory rates per minute. In respiratory perception, maximum speed can be understood as the maximum number of respiratory rates, such as the maximum number of respiratory rates per second or the maximum number of respiratory rates per minute.

[0512] For example, the sensing request information can also be understood as the capability information of the terminal device. For example, the sensing request information includes at least one of the following: the dynamic range of the analog-to-digital converter (ADC), the number of quantization bits of the ADC, the maximum sensing distance capability, the maximum sensing speed capability, the distance between the sensing transmitter and the sensing receiver, and the sensing signal carrier frequency.

[0513] The above information, including the number of frequencies, the frequency difference between any two frequencies, the sensing bandwidth, the first frequency offset, the number of phases, the phase difference between any two phases, and the phase offset, is associated with the capabilities of the terminal device.

[0514] Another configuration method is that the sensing transmitter itself determines the configuration information of the first sensing signal. For example, if the network device is the sensing transmitter, it determines the configuration information of the first sensing signal itself; or, if the terminal device is the sensing transmitter, it determines the configuration information of the first sensing signal itself.

[0515] For example, the sensing transmitter can determine the configuration information of the first sensing signal based on at least one of the sensing service requirement information, sensing service type information, and terminal device capability information, as described above.

[0516] Based on the above configuration methods, the signaling interaction process is clarified. Flexible configuration of the first sensing signal based on business needs, and the allocation of sensing resources that better meet business requirements, can improve the reliability of sensing services. A reasonable resource size can be allocated to the sensing signal, ensuring that the resource size aligns with the needs of the sensing service. More sensing resources are allocated to important sensing services, and correspondingly, fewer sensing resources are allocated to less important sensing services. Thus, from a system perspective, this ensures that all types of sensing services have appropriate sensing resources, guaranteeing the reliability of sensing at the system level. The sensing transmitter and / or sensing receiver can request sensing resources according to the needs of the sensing service, improving system efficiency.

[0517] In this embodiment, the first frequency difference Δf can be associated with at least one of the following information: sensing scene, sensing service type, confidence level, accuracy of positioning estimation, accuracy of velocity estimation, distance resolution, velocity resolution, maximum distance, maximum velocity, maximum sensing service latency, refresh rate, missed detection rate, and false alarm rate. Alternatively, the second frequency difference Δf A It can be associated with at least one of the following: sensing scene, sensing service type, confidence level, accuracy of positioning estimation, accuracy of velocity estimation, distance resolution, velocity resolution, maximum distance, maximum velocity, maximum sensing service latency, refresh rate, missed detection rate, and false alarm rate. Alternatively, sensing bandwidth BW. S It can be associated with at least one of the following information: sensing scene, sensing service type, confidence level, accuracy of positioning estimation, accuracy of velocity estimation, distance resolution, velocity resolution, maximum distance, maximum velocity, maximum sensing service latency, refresh rate, missed detection rate, and false alarm rate. Alternatively, the first frequency offset fo can be associated with at least one of the following information: sensing scene, sensing service type, confidence level, accuracy of positioning estimation, accuracy of velocity estimation, distance resolution, velocity resolution, maximum distance, maximum velocity, maximum sensing service latency, refresh rate, missed detection rate, and false alarm rate. Alternatively, the second frequency offset Δf 1,2 It can be associated with at least one of the following information: sensing scene, sensing service type, confidence level, accuracy of positioning estimation, accuracy of velocity estimation, distance resolution, velocity resolution, maximum distance, maximum velocity, maximum sensing service latency, refresh rate, missed detection rate, and false alarm rate.

[0518] It is understandable that the first resource set includes the number of frequency units M, and the first resource and / or the second resource includes the number of frequency units M. A First frequency difference Δf, second frequency difference Δf A Perceived bandwidth BW S First frequency offset fo, second frequency offset Δf 1,2The value of at least one parameter is related to the capabilities of the terminal device. The capabilities of the terminal device can be at least any one of the following: ADC dynamic range, ADC quantization bits, maximum sensing distance capability, maximum sensing speed capability, distance between the sensing transmitter and the sensing receiver, and sensing signal carrier frequency.

[0519] S502. The sensing receiver determines the information of the sensing target based on at least one of the following: information from the conjugate multiplication of the first sub-signal and the second sub-signal, information from the amplitude division, and information from the phase subtraction.

[0520] After receiving the first sub-signal and the second sub-signal, the sensing receiver can perform at least one of the following operations on the first sub-signal and the second sub-signal: conjugate multiplication, amplitude division, and phase subtraction, to obtain at least one of the following information: information from the conjugate multiplication of the first sub-signal and the second sub-signal, information from the amplitude division, and information from the phase subtraction. Based on at least one of the following information from the conjugate multiplication of the first sub-signal and the second sub-signal, information from the amplitude division, and information from the phase subtraction, the information of the sensing target is determined.

[0521] For example, after the sensing receiver receives the first sub-signal and the second sub-signal, it can perform conjugate multiplication on the first sub-signal and the second sub-signal to obtain the information of the conjugate multiplication of the first sub-signal and the second sub-signal, and determine the information of the sensing target based on the information of the conjugate multiplication of the first sub-signal and the second sub-signal.

[0522] For example, after the sensing receiver receives the first sub-signal and the second sub-signal, it can divide the amplitude of the first sub-signal and the second sub-signal to obtain the information of the amplitude division of the first sub-signal and the second sub-signal, and determine the information of the sensing target based on the information of the amplitude division of the first sub-signal and the second sub-signal.

[0523] For example, after the sensing receiver receives the first sub-signal and the second sub-signal, it can subtract the phases of the first sub-signal and the second sub-signal to obtain the phase difference information of the first sub-signal and the second sub-signal, and determine the information of the sensing target based on the phase difference information of the first sub-signal and the second sub-signal.

[0524] For example, after the sensing receiver receives the first sub-signal and the second sub-signal, it can divide the amplitude of the first sub-signal and subtract the phase of the second sub-signal to obtain information about the division of the amplitude of the first sub-signal and the subtraction of the phase of the first sub-signal and the second sub-signal. Based on the information about the division of the amplitude of the first sub-signal and the subtraction of the phase of the first sub-signal and the second sub-signal, the information of the sensing target can be determined.

[0525] In this context, amplitude division and phase subtraction can be understood as division. That is, after the sensing receiver receives the first sub-signal and the second sub-signal, it can divide the first sub-signal and the second sub-signal to obtain the information of the division between the first sub-signal and the second sub-signal, and determine the information of the sensing target based on the information of the division between the first sub-signal and the second sub-signal.

[0526] This embodiment involves a sensing receiver, which can reduce hardware costs while overcoming the impact of channel variations on sensing. A sensing receiver can be understood as a port, a radio frequency chain (RF chain), a radio frequency integrated circuit (RF IC), a baseband chain, an antenna, an antenna element, an antenna array element, a remote unit, or a radio unit. For example, the sensing receiver receives a first sensing signal from a first resource set at a first port, where the first port is a port; or, it receives the first sensing signal from the first resource set at a first radio frequency channel, where the first radio frequency channel is a transmission channel; or, it receives the first sensing signal from the first resource set at a first radio frequency integrated circuit, where the first radio frequency integrated circuit is a radio frequency integrated circuit; or, it receives the first sensing signal from the first resource set at a first baseband channel, where the first baseband channel is a baseband channel; or, it receives the first sensing signal from the first resource set at a first antenna, where the first antenna is an antenna; or, it receives the first sensing signal from the first resource set at a first antenna element, where the first antenna element is an antenna element; or, it receives the first sensing signal from the first resource set at a first remote radio frequency unit, where the first remote radio frequency unit is a remote radio frequency unit; or, it receives the first sensing signal from the first resource set at a first wireless unit, where the first wireless unit is a wireless unit.

[0527] The process of determining the information of the sensing target can also be referred to as operating the sensing service, or simply as performing sensing. The information of the sensing target includes at least one of the following: motion information of the sensing target, motion change information of the sensing target, distance information of the sensing target, speed information of the sensing target, and angle information of the sensing target. In other words, determining the information of the sensing target can be replaced by determining at least one of the following: motion information, motion change information, distance information, speed information, and angle information.

[0528] The target of perception can be at least one of an object, a device, or an environment.

[0529] Conjugate multiplication includes multiplying the first sub-signal by the conjugate of the second sub-signal, or multiplying the conjugate of the first sub-signal by the second sub-signal. The conjugate can be represented as conj(·) or real(·) - i × imag(·), where i is the imaginary unit, real(·) represents the real part, and imag(·) represents the imaginary part. For example, the first sub-signal s... m The conjugate of is real(s) m )-i×imag(s m For example, the second sub-signal s n The conjugate of is real(s) n )-i×imag(s n ).

[0530] Conjugate multiplication can be: s m ×conj(s n ) = [real(s m )+i×imag(s m )]×[real(s n )-i×imag(s n )]=real(s m )×real(s n )+imag(s m )×imag(s n )+i×[imag(s m )×real(s n )-real(s m )×imag(s n It can also be s. n ×conj(s m ) = [real(s n )+i×imag(s n )]×[real(s m )-i×imag(s m )]=real(s m )×real(s n )+imag(s m )×imag(s n )+i×[imag(s n )×real(s m )-real(s n )×imag(s m )).

[0531] For example, the sensing transmitter sends a second sensing signal, the second sensing signal including a third sub-signal and a fourth sub-signal represented as exp(2jπf1t) and exp(2jπf2t), respectively. The sensing receiver receives a first sensing signal including a first sub-signal and a second sub-signal. The first sub-signal s m Represented as: [α1+α2exp(2jπΔd1(t)f1 / c)]exp(2jπf1t+2jπd1f1 / c)*h1(t); and the second sub-signal s n This can be expressed as: [α1+α2exp(2jπΔd1(t)f2 / c)]exp(2jπf2t+2jπd1f2 / c)*h2(t). Then, the conjugate multiplication of the first and second sub-signals can be expressed as: s m (t)*conj(s n (t)). Where f1 is the frequency unit carrying the first sub-signal, f2 is the frequency unit carrying the second sub-signal, t represents time (i.e., Y first time units), α1 represents the energy attenuation of the first sensing signal through the "sensing transmitter-sensing receiver", α2 represents the energy attenuation of the first sensing signal through the "sensing transmitter-sensing target-sensing receiver", d1 represents the distance between the sensing transmitter and the sensing receiver, Δd1(t) represents the path difference between "sensing transmitter-sensing target-sensing receiver" and "sensing transmitter-sensing receiver", c represents the speed of light, h1(t) represents the experienced channel of the first sub-signal and / or the third sub-signal, and h2(t) represents the experienced channel of the second sub-signal and / or the fourth sub-signal.

[0532] The influence of the channel is mainly in the time-varying component; that is, if the duration Tw of the sensing window exceeds the correlation time, it will be affected by the time-varying channel, and vice versa. The correlation time is inversely proportional to the frequency. The time-varying channel components in h1(t) and h2(t) are respectively... and In other words, the correlation times of the channel are c / v·f1 and c / v·f2, respectively.

[0533] For the joint information model (conjugate multiplication, amplitude division, and / or phase subtraction), the influence of channels h1(t), h2(t), can be eliminated as much as possible using a single sensing receiver while reflecting the target movement information. After conjugate multiplication (or amplitude division and phase subtraction), the time-varying channel part is... This is equivalent to the coherence time becoming c / v·(f2-f1). With a larger coherence time, the duration Tw of the sensing window is more likely to meet the requirement of being smaller than the coherence time. When f2-f1 is sufficiently small, the time-varying part of the channel approaches 0 (the coherence time approaches infinity).

[0534] For example, the frequency domain resources of the first resource set include M frequency elements. M of these M frequency elements... A The frequency domain resources of the first resource are M frequency units. A A first frequency unit; M of the M frequency units B Each frequency unit is a frequency domain resource of the second resource, namely M. B A second frequency unit.

[0535] Optionally, the frequency domain resources of the first resource include M A The frequency domain resources of the first frequency unit and / or the second resource include M B A second frequency unit. Where M A M is an integer greater than or equal to 1. B It is an integer greater than or equal to 1.

[0536] The number of first frequency units included in the frequency domain resources of the first resource is equal to the number of second frequency units included in the frequency domain resources of the second resource, that is, M A It can be equal to M B .

[0537] The frequency domain spacing between the first frequency unit and the second frequency unit can be less than or equal to a second threshold. Alternatively, the frequency domain spacing between the m-th first frequency unit included in the first resource and the m-th second frequency unit included in the second resource can be less than or equal to a second threshold, where m is greater than or equal to 1 and less than or equal to M. A Integers.

[0538] The frequency domain spacing between the first frequency unit and the second frequency unit can be greater than or equal to a third threshold. Alternatively, the frequency domain spacing between the m-th first frequency unit included in the first resource and the m-th second frequency unit included in the second resource can be greater than or equal to the third threshold. Where m is greater than or equal to 1 and less than or equal to M. A Integers.

[0539] The above conjugate multiplication can be understood as multiplying the conjugate of the sensing signal carried in the m-th first frequency unit and the sensing signal carried in the m-th second frequency unit. The above amplitude division can be understood as dividing the sensing signal carried in the m-th first frequency unit by the sensing signal carried in the m-th second frequency unit. The above phase subtraction can be understood as subtracting the phase of the sensing signal carried in the m-th first frequency unit from the phase of the sensing signal carried in the m-th second frequency unit.

[0540] Further, the information of the sensing target is determined based on Y pieces of first information, each of the Y pieces of first information being obtained based on a first sensing signal received in each of the Y first time units. The sensing receiver receives Y first sensing signals in the Y first time units. Correspondingly, the sensing transmitter receives Y first sensing signals in the Y first time units.

[0541] The conjugate multiplication of Y first sensing signals can be understood as multiplying the conjugate of the sensing signal carried in the m-th first frequency unit and the sensing signal carried in the m-th second frequency unit in each first time unit. This yields Y pieces of information from the conjugate multiplication. The amplitude division of Y first sensing signals can be understood as dividing the sensing signal carried in the m-th first frequency unit and the sensing signal carried in the m-th second frequency unit in each first time unit. This yields Y pieces of information from the amplitude division. The phase subtraction of Y first sensing signals can be understood as subtracting the phase of the sensing signal carried in the m-th first frequency unit and the sensing signal carried in the m-th second frequency unit in each first time unit. This yields Y pieces of information from the phase subtraction.

[0542] The sensing signal carried on the first frequency unit can also be understood as the first sub-signal carried on the first frequency unit; the sensing signal carried on the second frequency unit can also be understood as the second sub-signal carried on the second frequency unit. The m-th first frequency unit can be denoted as the m1-th first frequency unit, and similarly, the m-th second frequency unit can be denoted as the m1-th second frequency unit.

[0543] The time domain range of the Y first time units can be considered as a sensing window, or the time domain of the Y first time units belongs to the sensing window. The sensing receiver determines the information of the sensing target based on the first sensing signal and / or the second sensing signal accumulated within the sensing window. The duration of the sensing window is denoted as Tw. The Y first time units can be represented by t, that is, the complex domain signal is s. n (t) and s m (t) represents a time series over Y first time units. For example, t = {0, 1, 2, ..., Y-1}, or t = {1, 2, 3, ..., Y}, or t = {a, a+1, a+2, ..., a+Y-1}.

[0544] For example, if the sensing receiver triggers sensing at time unit n, then according to the sensing window in [nT] A ,nT B The first sensing signal within a period of [ ] determines the information of the sensing target. The sensing window can also include the concept of the frequency domain; for example, the sensing window may include the frequency domain resources of the first resource set. Where T B For sensing processing time, such as TB The value can be any one of the time slots {0,1,2,3,4,5,6,7,8,9,10}. Where T... A -T B To sense the duration of the window, T A T B The relationship between Tw and Tw satisfies Tw = T A -T B .

[0545] For example, the Y first time units can be discrete time units within the perception window or continuous time units within the perception window. The first time unit can be a symbol, or a symbol within a time slot.

[0546] Furthermore, within the Y first time units (or, within the perception window), the information of the perceived target is determined based on at least one of the information obtained by multiplying the first sub-signal and the second sub-signal by their conjugates, dividing the amplitudes, and subtracting the phases.

[0547] Performing an FFT on the first sensing signal received in the first time unit yields a complex signal in the frequency domain, which represents the amplitude and phase information at each frequency unit. Specifically, performing an FFT on the first sensing signal received in each first time unit yields the sensing signal at each frequency unit in the first resource set. For example, the amplitude Amp and phase Ang of the first sensing signal on the first resource, and the amplitude Amp and phase Ang of the first sensing signal on the second resource, can be obtained. The sensing signal at each frequency unit can be M... A The first sub-signal carried by each first frequency unit, and / or, the sensed signal on each frequency unit can be M A The second sub-signal is carried by the second frequency unit.

[0548] Taking the first sensing signal and / or the second sensing signal as having four frequency units RE1, RE2, RE3, and RE4 as an example, the indices of these four frequency units are in ascending or descending order. The complex frequency domain signal of the first sensing signal on RE1 is s1, where |s1| is the amplitude Amp1 and ∠(s1) is the phase Ang1; the complex frequency domain signal of the first sensing signal on RE2 is s2, where |s2| is the amplitude Amp2 and ∠(s2) is the phase Ang2; the complex frequency domain signal of the first sensing signal on RE3 is s3, where |s3| is the amplitude Amp3 and ∠(s3) is the phase Ang3; the complex frequency domain signal of the first sensing signal on RE4 is s4, where |s4| is the amplitude Amp4 and ∠(s4) is the phase Ang4.

[0549] The first sub-signal includes RE m complex domain signal sm . s m (t) represents the frequency domain complex signal (m = 1, 2, 3, ..., M) at the m-th frequency unit in the Y first time units. Similarly, the second sub-signal is included in RE. n complex domain signal s n . s n (t) represents a complex frequency domain signal (n = 1, 2, 3, ..., M) at the nth frequency unit across Y first time units. Here, t represents the time sequence across the Y first time units. The mth frequency unit is the mth frequency unit among the M frequency units included in the frequency domain resources of the first resource set. The value of m is an integer from 1 to M, or an integer from 0 to M-1. The nth frequency unit is the nth frequency unit among the M frequency units included in the frequency domain resources of the first resource set. The value of n is an integer from 1 to M, or an integer from 0 to M-1.

[0550] For example, Y first sensing signals are received in Y first time units, the frequency domain complex signal on RE1 is s1(t), the frequency domain complex signal on RE2 is s2(t), the frequency domain complex signal on RE3 is s3(t), and the frequency domain complex signal on RE4 is s4(t).

[0551] In the Y first time units, based on the frequency domain complex signal s in the nth frequency unit. n (t) and the frequency domain complex signal s at the m-th frequency unit m The information from the conjugate multiplication of (t) determines the information of the perceived target. The information from the conjugate multiplication is s. n (t)×conj(s m (t) can also be s m (t)×conj(s n (t)). s n The conjugate of (t) can be understood as conj(s) n (t))=real(s n (t))-imag(s n (t)), and correspondingly, s m The conjugate of (t) can be understood as conj(s) m (t))=real(s m (t))-imag(s m (t)).

[0552] In the Y first time units, based on the frequency domain complex signal s in the nth frequency unit. n (t) and the frequency domain complex signal s at the m-th frequency unit m The information obtained by dividing the amplitude of (t) determines the information of the perceived target. The information obtained by dividing the amplitude is... It can also be

[0553] In the Y first time units, based on the frequency domain complex signal s in the nth frequency unit. n (t) and the frequency domain complex signal s at the m-th frequency unit m The information obtained by subtracting the phase from (t) determines the information of the perceived target. The information obtained by dividing the amplitude is ∠(s). n (t))-∠(s m (t) can also be ∠(s) m (t))-∠(s n (t)).

[0554] In the Y first time units, based on the frequency domain complex signal s in the nth frequency unit. n (t) and the frequency domain complex signal s at the m-th frequency unit m The information obtained by dividing (t) determines the information of the perceived target. The information obtained by dividing is s. n (t) / s m (t) can also be s m (t) / s n (t). The information from the division can also be represented as amplitude division and phase subtraction. or

[0555] In this embodiment, |·| represents finding the magnitude or modulus, ∠(·) represents finding the angle, phase or initial phase, real(·) represents finding the real part, imag(·) represents finding the imaginary part, and conj(·) represents conjugate.

[0563] b) M of the first resource A M of the first frequency unit and the second resource A The second frequency units can also be distributed continuously.

[0564] In other words, each first frequency unit of the first resource and each second frequency unit of the second resource are interleaved.

[0565] For example, the first frequency units are RE1 and RE2, and the second frequency units are RE3 and RE4. The first sub-signal is the sensing signal carried on RE1 and RE2, and the second sub-signal is the sensing signal carried on RE3 and RE4.

[0566] For example, conjugate multiplication can be understood as the conjugate multiplication of the sensing signal carried on RE1 with the sensing signal carried on RE3, and the conjugate multiplication of the sensing signal carried on RE2 with the sensing signal carried on RE4.

[0569] For example, division can be understood as dividing the sensing signal carried on RE1 by the sensing signal carried on RE3, and dividing the sensing signal carried on RE2 by the sensing signal carried on RE4. The division information in the Y first time units can be understood as the set of division information obtained by dividing the sensing signal carried on RE1 by the sensing signal carried on RE3 in each first time unit; and the set of division information obtained by dividing the sensing signal carried on RE2 by the sensing signal carried on RE4 in each first time unit.

[0570] c) M of the first resource A M of the first frequency unit and the second resource A The second frequency units can also partially overlap.

[0571] For example, the first frequency unit is RE1, RE2, and RE3, and the second frequency unit is RE2, RE3, and RE4. The first sub-signal is the sensing signal carried on RE1, RE2, and RE3, and the second sub-signal is the sensing signal carried on RE2, RE3, and RE4.

[0572] For example, conjugate multiplication can be understood as the conjugate multiplication of the sensing signal carried on RE1 with the sensing signal carried on RE2, the conjugate multiplication of the sensing signal carried on RE2 with the sensing signal carried on RE3, and the conjugate multiplication of the sensing signal carried on RE3 with the sensing signal carried on RE4. The information obtained from the conjugate multiplication across the Y first time units can be understood as the set of information obtained from the conjugate multiplication of the sensing signal carried on RE1 with the sensing signal carried on RE2 in each first time unit; the set of information obtained from the conjugate multiplication of the sensing signal carried on RE2 with the sensing signal carried on RE3 in each first time unit; and the set of information obtained from the conjugate multiplication of the sensing signal carried on RE3 with the sensing signal carried on RE4 in each first time unit.

[0573] For example, amplitude division can be understood as dividing the amplitude of the sensing signal carried on RE1 by the amplitude of the sensing signal carried on RE2, dividing the amplitude of the sensing signal carried on RE2 by the amplitude of the sensing signal carried on RE3, and dividing the amplitude of the sensing signal carried on RE3 by the amplitude of the sensing signal carried on RE4.

[0574] For example, phase subtraction can be understood as subtracting the phase of the sensing signal carried on RE1 from the phase of the sensing signal carried on RE2, subtracting the phase of the sensing signal carried on RE2 from the phase of the sensing signal carried on RE3, and subtracting the phase of the sensing signal carried on RE3 from the phase of the sensing signal carried on RE4. The phase subtraction information in the Y first time units can be understood as the set of phase subtraction information obtained by subtracting the phase of the sensing signal carried on RE1 from the phase of the sensing signal carried on RE2 in each first time unit; the set of phase subtraction information obtained by subtracting the phase of the sensing signal carried on RE2 from the phase of the sensing signal carried on RE3 in each first time unit; and the set of phase subtraction information obtained by subtracting the phase of the sensing signal carried on RE3 from the phase of the sensing signal carried on RE4 in each first time unit.

[0575] For example, division can be understood as the division of the sensing signal carried on RE1 with the sensing signal carried on RE2, the division of the sensing signal carried on RE2 with the sensing signal carried on RE3, and the division of the sensing signal carried on RE3 with the sensing signal carried on RE4. The division information in the Y first time units can be understood as the set of division information obtained by dividing the sensing signal carried on RE1 with the sensing signal carried on RE2 in each first time unit; the set of division information obtained by dividing the sensing signal carried on RE2 with the sensing signal carried on RE3 in each first time unit; and the set of division information obtained by dividing the sensing signal carried on RE3 with the sensing signal carried on RE4 in each first time unit.

[0576] For example, before or after performing at least one of the following processes on the first and second sub-signals: conjugate multiplication, amplitude division, and phase subtraction, sampling, digital-to-analog conversion, automatic gain control, etc., may also be performed on the first and second sub-signals.

[0577] For example, based on the amplitude information Amp m,n (t) and / or phase information Ang m,n (t) Determine the information of the perceived target. Amplitude information (Amp) m,n (t) can be the amplitude information after conjugate multiplication, or the amplitude information after amplitude division. Phase information Ang m,n (t) can be the phase information after conjugate multiplication or the phase information after phase subtraction.

[0578] In one example, the amplitude information Amp m,n (t) can be the amplitude information of the conjugate multiplication of the first sub-signal and the second sub-signal. Over Y first time units, the amplitude information of the conjugate multiplication includes Amp. m,n (t)=|s n (t)×conj(s m (t))|or Amp m,n (t)=|s m (t)×conj(s n (t))|.

[0579] In another example, amplitude information Amp m,n (t) can be the amplitude information of the information obtained by dividing the amplitudes of the first sub-signal and the second sub-signal. In the Y first time units, the amplitude information of the amplitude division includes Amp. m,n (t)=|s n (t)| / |s m (t)|or Amp m,n (t)=|s m (t)| / |s n (t)|.

[0580] In another example, phase information Ang m,n (t) can be the phase information of the conjugate multiplication of the first sub-signal and the second sub-signal. In Y first time units, the phase information of the conjugate multiplication includes Ang. m,n (t)=∠(s n (t)×conj(s m (t)))or Ang m,n (t)=∠(s m (t)×conj(s n (t))).

[0581] In another example, phase information Amp m,n (t) can be the first sub-signal and the second sub-signal. In Y first time units, the phase information of the phase subtraction includes Ang. m,n (t)=∠(s n (t))-∠(s m (t)) or Ang m,n (t)=∠(s m (t))-∠(s n (t)).

[0582] Furthermore, the amplitude information in at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction can be smoothed; and / or, the phase information in at least one of the information from the conjugate multiplication of the first sub-signal and the second sub-signal, the information from the amplitude division, and the information from the phase subtraction can be smoothed.

[0583] Optionally, for amplitude information Amp m,n (t) and / or phase information Ang m,n (t) is smoothed. Specifically, the amplitude information Amp can be smoothed over each of the Z first time units in the Y first time units. m,n (t) and / or phase information Ang m,n (t) Perform smoothing filtering. Z is a positive integer less than or equal to Y. The benefit of smoothing filtering is that it can reduce the impact of noise on the sensing results.

[0584] For example, the amplitude information Amp in each of the Z first time units out of the Y first time units. m,n (t) Perform smoothing filtering, and / or, for the phase information Ang in each of the Z first time units in the Y first time units. m,n (t) is used for smoothing filtering.

[0585] For example, the real part real(s) of the information from the conjugate multiplication over every Z first time units in Y first time units. n (t)×conj(s m (t))) Perform smoothing filtering, and / or, for the information of the conjugate multiplication at each of the Z first time units in the Y first time units, the imaginary part imag(s) n (t)×conj(s m (t))) Perform smoothing filtering.

[0586] For example, the real part real(s) of the information from the conjugate multiplication over every Z first time units in Y first time units. m (t)×conj(s n(t))) Perform smoothing filtering, and / or, for the information of the conjugate multiplication at each of the Z first time units in the Y first time units, the imaginary part imag(s) m (t)×conj(s n (t))) Perform smoothing filtering.

[0587] The duration Z of the smoothing filter window can be determined based on the perceived latency. For example, the duration Z of the smoothing filter window is less than or equal to the perceived latency * 2.

[0588] Furthermore, the amplitude and / or phase information from at least one of the following—the information from the conjugate multiplication of the first and second sub-signals, the information from amplitude division, and the information from phase subtraction—can be processed using a Fast Fourier Transform (FFT) and / or a Multiple Signal Classification (MUSIC) algorithm to obtain the first sensing information. The peak value of the FFT / MUSIC processing result corresponds to the target velocity on the horizontal axis. In this application, FFT can be simply referred to as Fourier Transform.

[0589] The first resource includes M A A first frequency unit, the second resource includes M A There are two second frequency units. The m-th frequency unit belongs to the frequency domain resource of the first resource, and the n-th frequency unit belongs to the frequency domain resource of the second resource. The m-th first frequency unit in the first resource and the n-th second frequency unit in the second resource are called a pair of frequency units. For example, m = n. The M-th frequency unit in the first resource... A M in the first frequency unit and the second resource A The second frequency unit is called M. A For frequency units.

[0590] Similarly, the first resource carries the first sensing signal, and the second resource carries the second sensing signal. Then, the first sub-signal carried by the m-th first frequency unit in the first resource and the second sub-signal carried by the n-th second frequency unit in the second resource are called a pair of sensing signals. For example, m = n. The M-th frequency unit in the first resource... A The first sub-signal carried by the first frequency unit and the M in the second resource A The second sub-signal carried by the second frequency unit is called the M-pair sensing signal.

[0591] The information of the sensing target is determined by multiplying the conjugate of the sensing signals on the first frequency unit and the sensing signals on the second frequency unit; or, the information of the sensing target is determined by dividing the amplitudes of the sensing signals on the first frequency unit and the sensing signals on the second frequency unit; or, the information of the sensing target is determined by subtracting the phases of the sensing signals on the first frequency unit and the sensing signals on the second frequency unit; or, the information of the sensing target is determined by dividing the amplitudes and subtracting the phases of the sensing signals on the first frequency unit and the sensing signals on the second frequency unit.

[0592] The sensing signals from the first frequency unit and the second frequency unit can determine one amplitude information Amp. m,n (t) and / or 1 phase information Ang m,n (t). M A M can be determined from the sensing signals on the first frequency unit and the sensing signals on the second frequency unit. A Amp amplitude information m,n (t) and / or M A Phase information Ang m,n (t). That is, the M of the first sensing signals received in the first Y time units can be obtained. A Amp amplitude information m,n (t) and / or M A Phase information Ang m,n (t).

[0593] Optionally, for amplitude information Amp m,n (t) and / or phase information Ang m,n (t) Perform FFT and / or MUSIC processing.

[0594] Figure 6 shows a schematic diagram illustrating FFT or MUSIC processing of amplitude and / or phase information for a single sensing target, as exemplified by an embodiment of this application. The M values ​​are processed over Y first time units. A =1 Amp of amplitude information of the sensing signal on the first frequency unit and the sensing signal on the second frequency unit m,n (t) and / or phase information Ang m,n(t) Performing FFT or MUSIC processing can determine information about the perceived target, such as its velocity. The information after FFT or MUSIC processing is called the first perception information (curve 1 in Figure 6). The first perception information includes perception information corresponding to different motion frequencies. Among the perception information corresponding to non-zero motion frequencies, the peak value of the perception information corresponds to the first motion frequency f, which is associated with the velocity of the perceived target. The horizontal axis corresponding to the peak value is the first motion frequency f, so in respiratory perception, the target's respiratory information bpm = 60 * f. In order to distinguish the frequency carrying the perception signal from the frequency of fluctuation, in this embodiment, the frequency of fluctuation is called the motion frequency.

[0595] For example, if the motion frequency range corresponding to FFT (or MUSIC) processing is [0, fs], then the first motion frequency is determined based on the peak value of the first sensing information within the range of (0, fs]. As another example, if the motion frequency range corresponding to FFT (or MUSIC) processing is [-fs / 2, fs / 2], then the first motion frequency is determined based on the peak values ​​of the first sensing information within the ranges of [-fs / 2, 0) and (0, fs / 2]. Components with motion frequencies equal to 0 (or part thereof) do not reflect the target's motion change information, but are generally the motion frequencies corresponding to the peak values ​​of the first sensing information. Components with motion frequencies not equal to 0 reflect the target's motion change information; therefore, components with motion frequencies equal to 0 need to be excluded, which simplifies the signal processing flow and improves the reliability of sensing.

[0596] For M in Y first time units A =1 Amp of amplitude information of the sensing signal on the first frequency unit and the sensing signal on the second frequency unit m,n (t) and / or phase information Ang m,n (t) Performing FFT or MUSIC processing can determine the information of C sensed targets, such as the velocity information of C sensed targets, meaning that C targets have different velocities, where C is a positive integer greater than 1. In the sensed information corresponding to non-zero motion frequencies, the C peaks of the sensed information correspond to C first motion frequencies, and the C first motion frequencies are associated with the velocities of C sensed targets. As shown in Figure 7, this is a schematic diagram of FFT or MUSIC processing of amplitude information and / or phase information for multiple sensed targets, as exemplified by an embodiment of this application. For example, there are C = 2 targets, and these 2 targets have different velocities. Then, the 2 peaks of the first sensed information correspond to 2 first motion frequencies, which are respectively associated with the velocities of the 2 sensed targets.

[0597] Figure 8 shows another schematic diagram illustrating FFT or MUSIC processing of amplitude and / or phase information for a single sensing target, as exemplified by an embodiment of this application. Y first time units, M... A= 2 pairs of sensing signals from the first frequency unit and the second frequency unit can determine two amplitude information Amp. m,n (t) and / or 2 phase information Ang m,n (t), representing two sets of sensing information (curves 1 and 2 in Figure 8). Each set of sensing information includes sensing information corresponding to different motion frequencies. Among the sensing information corresponding to non-zero motion frequencies, the sensing information with the largest peak value is the first sensing information. As shown in Figure 8, the peak value of the sensing information corresponding to curve 1 is greater than the peak value of the sensing information corresponding to curve 2; therefore, the sensing information corresponding to curve 1 is considered the first sensing information. Among the sensing information corresponding to non-zero motion frequencies, the peak value of the first sensing information corresponds to the first motion frequency, which is associated with the speed of the sensed target.

[0598] Figure 9 shows another schematic diagram illustrating FFT or MUSIC processing of amplitude and / or phase information for multiple sensing targets, as exemplified by an embodiment of this application. Y first time units, M... A =2 The joint information of the sensing signals in the first frequency domain unit and the sensing signals in the second frequency domain unit can determine M. A = 2 amplitude information Amp m,n (t) and / or M A = 2 phase information Ang m,n (t), which represents two pieces of perceived information (curve 1 and curve 2 in Figure 9). In other words, the M of the first perceived signals received in the Y first time units can be obtained. A Amp amplitude information m,n (t) and / or M A Phase information Ang m,n (t). Among the perceived information corresponding to non-zero motion frequencies, the perceived information with the largest peak value is the first perceived information. Among the perceived information corresponding to non-zero motion frequencies, the C peak values ​​of the first perceived information correspond to C first motion frequencies, and the C first motion frequencies are associated with C perceived target velocities. As shown in Figure 9, for example, there are C = 2 targets, and these 2 targets have different velocities. The peak values ​​of the perceived information corresponding to curve 1 are all greater than the peak values ​​of the perceived information corresponding to curve 2. Therefore, the perceived information corresponding to curve 1 is the first perceived information, and the two peak values ​​of the first perceived information correspond to two first motion frequencies, which are respectively associated with the velocities of the two perceived targets.

[0599] As shown in Figures 6-9, determining the target information based on the peak value in the first sensing information corresponding to at least one non-zero motion frequency can improve the reliability of sensing. Removing information with a zero motion frequency removes the sensing signal directly coupled from the sensing transmitter to the sensing receiver. This is because information with a zero motion frequency corresponds to the static component of the first sensing signal and does not include the target information; correspondingly, information with non-zero motion frequencies corresponds to the dynamic component of the first sensing signal and includes the target information. By determining the peak value of the first sensing information in the non-zero motion frequencies, the influence of the static component on the sensing result can be eliminated, meaning that the portion including the target information can be extracted. For example, the static component includes the sensing signal transmitted from the sensing transmitter that arrives directly at the sensing receiver without being reflected or scattered by the target. In actual sensing, the signal energy of this static component is very large; removing information with a zero motion frequency is equivalent to removing the information of this static component from the first sensing signal.

[0600] FFT or MUSIC processing can reflect information about the sensed target, such as the speed of its motion. This is because, taking conjugate multiplication as an example, information about the sensed target can be obtained from the information obtained by multiplying the first and second sub-signals conjugately. For example, as the target moves away from the sensing receiver (or sensing transmitter), the amplitude or phase of the information obtained by multiplying the first and second sub-signals conjugately fluctuates. The frequency of this fluctuation reflects the speed of the sensed target's motion. After FFT or MUSIC processing, its peak value corresponds to the frequency of this fluctuation. To distinguish the frequency of the signal from the frequency of the fluctuation, in this application, the frequency of the fluctuation is referred to as the motion frequency.

[0601] Similarly, the amplitude division and phase subtraction information also exhibit fluctuations as the target moves away from the sensing receiver (or sensing transmitter). Consequently, after FFT or MUSIC processing, the peak value corresponds to the motion frequency of the sensed target.

[0602] Optionally, the velocities of multiple targets can be determined sequentially using interference cancellation (e.g., determining the bpm of multiple targets in respiratory sensing). The above process describes determining the information of the sensing target based on a first sensing signal transmitted in one time unit. Further, the sensing transmitter can also transmit Y first sensing signals in Y first time units. Correspondingly, the sensing receiver receives Y first sensing signals in Y first time units. The sensing receiver determines the information of the sensing target based on the Y first pieces of information, where each of the Y first pieces of information is obtained based on the first sensing signal received in each of the Y first time units.

[0603] For example, the frequency resources of the first resource and the second resource can be the same across the Y first time units; that is, the frequency resources of the first resource and the second resource remain unchanged in each of the Y first time units. This can save on resource configuration overhead.

[0604] According to an embodiment of this application, a sensing method is provided in which a sensing transmitter sends a sensing signal to a sensing receiver on a first resource set. The sensing signal includes a first sub-signal and a second sub-signal, which are respectively carried on different resources. This allows the sensing receiver to determine the information of the sensing target based on at least one of the following: information obtained by multiplying the first and second sub-signals by their conjugates, information obtained by dividing the amplitudes, and information obtained by subtracting the phases. This eliminates the need for multiple sensing receivers and reduces hardware costs. Furthermore, determining the information of the sensing target based on at least one of the following overcomes the problems of time-varying channels and random phases caused by Doppler, ensuring the accuracy of the sensing.

[0605] It is understood that, in the above embodiments, the methods and / or steps implemented by the sensing transmitter can also be implemented by components (e.g., chips or circuits) that can be used in the sensing transmitter; and the methods and / or steps implemented by the sensing receiver can also be implemented by components (e.g., chips or circuits) that can be used in the sensing receiver.
