Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to sensing methods and apparatus. Background Technology

[0002] In radar sensing technology, the maximum speed that radar can detect is determined by both the wavelength and the pulse repetition interval (PRI). The smaller the PRI, the larger the speed detection range.

[0003] Typically, radars use a fixed PRI (Primary Point of Detection) when transmitting sensing signals at the factory; that is, radars can only transmit sensing signals using a fixed PRI.

[0004] However, given a fixed PRI (Primary Parameter), the maximum sensing speed is also fixed. That is, the maximum speed at which a target can be sensed is fixed. In this case, if the target's speed exceeds the maximum sensing speed, speed measurement ambiguity will occur, leading to an error in the perceived target speed. Summary of the Invention

[0005] This application provides a sensing method and apparatus that can improve sensing performance.

[0006] Firstly, a sensing method is provided. This method can be executed by a Radio Access Network (RAN) node, or by components of the RAN node, such as the RAN node's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the RAN node's functions. The following description uses an RAN node as an example. The method includes: determining a first sensing resource, the time unit interval of which is a first interval; determining a second sensing resource, the time unit interval of which is a second interval, the second interval being smaller than the first interval, and the time unit interval of the sensing resource being the interval between adjacent time units within the sensing resource; and transmitting a sensing signal on the second sensing resource.

[0007] Based on this scheme, the interval between adjacent time units in the sensing resources carrying the sensing signals is adjustable rather than a fixed value, which can better adapt to sensing needs and improve sensing performance.

[0008] Specifically, the interval between adjacent time units in the sensing resources used to carry the sensing signal can be initially set to a larger interval. Subsequently, the interval between adjacent time units of the sensing resources can be adjusted to a smaller interval. Compared to before adjusting the time unit interval, the sensing speed range can be expanded, thereby achieving flexible adjustment of the sensing speed range. This allows for the identification of speed measurement ambiguity through different sensing speed ranges, accurately sensing the target speed, solving the speed measurement ambiguity problem, and improving sensing performance. Furthermore, compared to always configuring a small time unit interval for the sensing resources, i.e., always configuring a high density of sensing resources, the larger initial time unit interval of the sensing resources in this application's scheme saves on sensing resource overhead, thus avoiding the occupation of large amounts of time-frequency resources and preventing a decrease in communication performance, thereby reducing the impact of sensing on communication.

[0009] In one possible design, the method further includes: sending first configuration information, the first configuration information being used to configure at least one sensing resource, each of the at least one sensing resource having a QCL relationship with a reference resource, the at least one sensing resource including the first sensing resource; and sending second configuration information, the second configuration information being used to update the time unit interval of some or all of the at least one sensing resource having a QCL relationship with the first reference resource to a second interval. Wherein, the sensing resource obtained after updating the time unit interval of some or all of the sensing resources having a QCL relationship with the first reference resource to the second interval includes the second sensing resource.

[0010] Based on this possible implementation, after configuring the first sensing resource with the first configuration information, the time unit interval of the first sensing resource is updated with the second configuration information. Therefore, the second configuration information can be carried in the DCI. Compared with reconfiguring sensing resources with a smaller time unit interval, the effective delay time of the second sensing resource can be reduced, so that the updated time unit can take effect as soon as possible. This is because there is a certain reconfiguration delay when reconfiguring resources, and the update of the time unit interval of the sensing resource cannot take effect immediately.

[0011] In one possible design, the second configuration information includes first indication information and second indication information; wherein the first indication information is used to indicate the first sensing resource, and the second indication information is used to indicate the second interval.

[0012] In one possible design, the first indication information includes a resource identifier of a first sense resource, or a resource identifier of a first reference resource; and / or, the second indication information includes a ratio of a second interval to a first interval, or includes a second interval.

[0013] Based on this possible design, when the first indication information includes the resource identifier of the first sensing resource, it can accurately indicate the sensing resource that needs to be updated. When the first indication information includes the resource identifier of the first reference resource, it can indicate one or more sensing resources with a QCL relationship with it to be updated based on a single resource identifier. When there are multiple sensing resources with a QCL relationship with the first reference resource, signaling overhead can be saved compared to indicating the resource identifiers of each of the multiple sensing resources one by one.

[0014] Furthermore, when the second indication information includes the ratio of the second interval to the first interval, the second interval can be indicated with fewer bits, thereby saving signaling overhead. Including the second interval in the second indication information allows for more flexible indication of the second interval, enhancing its flexibility.

[0015] In one possible design, sending the second configuration information includes: receiving third indication information from a sensing network element, the third indication information indicating the time unit interval for updating a sensing resource that has a QCL relationship with the first reference resource; and sending the second configuration information according to the third indication information.

[0016] In one possible design, the third indication information includes at least one of the following: the resource identifier of the first sensing resource, the resource identifier of the first reference resource, the second interval, the maximum sensing speed, or the sensing requirement.

[0017] In one possible design, the method further includes: sending third configuration information, the third configuration information being used to configure at least one sensing resource, the at least one sensing resource including a third sensing resource, the time unit interval of the third sensing resource including a first interval and a second interval. Specifically, within a first time period, the time unit interval of the third sensing resource is the first interval, and the third sensing resource is the first sensing resource; within a second time period, the time unit interval of the third sensing resource is the second interval, and the third sensing resource is the second sensing resource; the first time period and the second time period do not overlap.

[0018] Based on this possible implementation, by configuring two time unit intervals for the same sensing resource with a single configuration message, the sensing speed range can be flexibly adjusted, which can reduce the overhead of configuration signaling.

[0019] In one possible design, the method further includes: sending a sensing signal on the first sensing resource.

[0020] In one possible design, the method further includes: acquiring a first sensing result, the first sensing result being determined based on a sensing signal carried on a first sensing resource; updating the time unit interval of the first sensing resource from a first interval to a second interval based on the first sensing result, thereby obtaining a second sensing resource.

[0021] Secondly, a sensing method is provided. This method can be executed by a terminal, or by components of the terminal, such as the terminal's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the terminal's functions. The following description uses a RAN node as an example. The method includes: determining a first sensing resource, the time unit interval of which is a first interval; determining a second sensing resource, the time unit interval of which is a second interval, the second interval being smaller than the first interval, and the time unit interval of the sensing resource being the interval between adjacent time units within the sensing resource; and receiving a sensing signal on the second sensing resource. The technical effects of this second aspect are similar to those of the first aspect described above, and will not be repeated here.

[0022] In one possible design, determining a first sensing resource includes: receiving first configuration information, the first configuration information being used to configure at least one sensing resource, each of the at least one sensing resource having a QCL relationship with a reference resource, and the at least one sensing resource including the first sensing resource. Determining a second sensing resource includes: receiving second configuration information, the second configuration information being used to update the time unit interval of some or all of the at least one sensing resource that has a QCL relationship with the first reference resource to a second interval.

[0023] In one possible design, the second configuration information includes first indication information and second indication information; wherein the first indication information is used to indicate the first sensing resource, and the second indication information is used to indicate the second interval.

[0024] In one possible design, the first indication information includes a resource identifier of a first sense resource, or a resource identifier of a first reference resource; and / or, the second indication information includes a ratio of a second interval to a first interval, or includes a second interval.

[0025] In one possible design, determining the first resource and determining the second resource includes: receiving third configuration information, which is used to configure at least one sensing resource, the at least one sensing resource including the third sensing resource, and the time unit interval of the third sensing resource including a first interval and a second interval. Specifically, within a first time period, the time unit interval of the third sensing resource is the first interval, and the third sensing resource is the first sensing resource; within a second time period, the time unit interval of the third sensing resource is the second interval, and the third sensing resource is the second sensing resource; the first time period and the second time period do not overlap.

[0026] In one possible design, the method further includes: receiving a sensing signal on a first sensing resource; and sending a first sensing result, the first sensing result being determined based on the sensing signal carried on the first sensing resource.

[0027] The technical effects of any possible design in the second aspect can be referred to the technical effects of the corresponding design in the first aspect mentioned above, and will not be repeated here.

[0028] In one possible design, combining the first or second aspect, the first sensing resource and the first reference resource have a quasi-co-located QCL relationship; the second sensing resource and the first reference resource have a QCL relationship.

[0029] Based on this possible design, the first sensing resource and the second sensing resource are associated with the same beam. Therefore, for the same beam direction, the solution of this application can configure the first sensing resource and the second sensing resource in the time domain, thereby flexibly adjusting the sensing speed range in the beam direction.

[0030] In one possible design, combining the first or second aspect, the resource identifier of the second sensing resource is the same as the resource identifier of the first sensing resource.

[0031] Combining the first or second aspect, in one possible design, the first and second sensing resources are periodic resources, and the first and second sensing resources are distributed alternately in the time domain.

[0032] Based on this possible design, the first sensing resource and the second sensing resource are distributed at intervals, enabling the receiver to perform joint detection based on the first sensing resource and the second sensing resource, thereby identifying speed measurement ambiguity and accurately sensing the speed of the target where speed measurement ambiguity occurs, thus improving sensing performance.

[0033] Thirdly, a sensing method is provided. This method can be executed by a RAN node, or by components of the RAN node, such as the RAN node's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the RAN node's functions. The following description uses a RAN node as an example. The method includes: transmitting a sensing signal on a first sensing resource; updating the time unit interval of the first sensing resource from a first interval to a second interval, where the second interval is smaller than the first interval, and the time unit interval of the sensing resource is the interval between adjacent time units in the sensing resource; and transmitting a sensing signal on the updated first sensing resource.

[0034] Based on this scheme, the interval between adjacent time units in the sensing resources used to carry the sensing signal can be initially set to a larger interval. Subsequently, the interval between adjacent time units of the sensing resources can be adjusted to a smaller interval. Compared with before adjusting the time unit interval, the sensing speed range can be expanded, thereby achieving flexible adjustment of the sensing speed range. Furthermore, by using different sensing speed ranges, speed measurement ambiguity can be identified, and the actual speed of the target can be accurately sensed, solving the problem of speed measurement ambiguity and improving sensing performance. In addition, compared with always configuring a small time unit interval for the sensing resources, i.e., always configuring a high density of sensing resources, the scheme of this application can save the overhead of sensing resources and reduce the impact of sensing on communication.

[0035] In one possible design, the method further includes: sending first configuration information, which is used to configure a first sensing resource; and sending second configuration information, which is used to update the time unit interval of the first sensing resource from a first interval to a second interval.

[0036] Fourthly, a sensing method is provided. This method can be executed by a terminal, or by components of the terminal, such as the terminal's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the terminal's functions. The following description uses a RAN node as an example. The method includes: receiving a sensing signal on a first sensing resource; updating the time unit interval of the first sensing resource from a first interval to a second interval, where the second interval is smaller than the first interval, and the time unit interval of the sensing resource is the interval between adjacent time units in the sensing resource; and receiving the sensing signal on the updated first sensing resource. The technical effects of this fourth aspect are similar to those of the third aspect described above, and will not be repeated here.

[0037] In one possible design, the method further includes: receiving first configuration information, the first configuration information being used to configure a first sensing resource; and receiving second configuration information, the second configuration information being used to update the time unit interval of the first sensing resource from a first interval to a second interval.

[0038] In conjunction with the third or fourth aspect, in one possible design, the first sensing resource and the first reference resource have a quasi-co-located QCL relationship.

[0039] Fifthly, a sensing method is provided. This method can be executed by a RAN node, or by components of the RAN node, such as the RAN node's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the RAN node's functions. The following description uses a RAN node as an example. The method includes: transmitting a sensing signal on a first sensing resource. The time unit interval of the first sensing resource includes a first interval and a second interval, the second interval being smaller than the first interval. The time unit interval of the sensing resource is the interval between adjacent time units within the sensing resource. Specifically, within a first time period, the time unit interval of the first sensing resource is the first interval; within a second time period, the time unit interval of the first sensing resource is the second interval; the first time period and the second time period do not overlap.

[0040] Based on this scheme, sensing resources can be configured with larger time unit intervals in one period and smaller time unit intervals in another period. This allows for flexible adjustment of the sensing speed range through different time unit intervals, enabling the identification of speed measurement ambiguity and accurate perception of the target's actual speed, thus resolving the speed measurement ambiguity problem and improving sensing performance. Furthermore, compared to consistently configuring sensing resources with smaller time unit intervals (i.e., consistently configuring high-density sensing resources), the scheme in this application can save on sensing resource overhead and reduce the impact of sensing on communication.

[0041] In one possible design, the method further includes: sending first configuration information, which is used to configure a first sensing resource.

[0042] Sixthly, a sensing method is provided. This method can be executed by a terminal, or by components of the terminal, such as the terminal's processor, chip, or chip system, or by a logic module or software capable of implementing all or part of the terminal's functions. The following description uses a RAN node as an example. The method includes: receiving a sensing signal on a first sensing resource. The time unit interval of the first sensing resource includes a first interval and a second interval, the second interval being smaller than the first interval. The time unit interval of the sensing resource is the interval between adjacent time units within the sensing resource. Specifically, within a first time period, the time unit interval of the first sensing resource is the first interval; within a second time period, the time unit interval of the first sensing resource is the second interval; the first time period and the second time period do not overlap. The technical effects of this sixth aspect are similar to those of the fifth aspect described above, and will not be repeated here.

[0043] In one possible design, the method further includes: receiving first configuration information, which is used to configure a first sensing resource.

[0044] In conjunction with the fifth or sixth aspect, in one possible design, the first configuration information is also used to configure the first time period and / or the second time period.

[0045] In conjunction with the fifth or sixth aspect, in one possible design, the first time period and the second time period are periodic time periods, with the first time period and the second time period alternating.

A terminal determines the first sensing resource with the first interval and the second sensing resource with the second interval, and receives the sensing signal on the second sensing resource.

[0047] In one possible design, the method further includes: a RAN node sending first configuration information, the first configuration information being used to configure at least one sensing resource, each of the at least one sensing resource having a QCL relationship with a reference resource, the at least one sensing resource including the first sensing resource; a terminal receiving the first configuration information, the first configuration information determining the first sensing resource; the RAN node sending second configuration information, the second configuration information being used to update the time unit interval of some or all of the at least one sensing resource having a QCL relationship with the first reference resource to a second interval; the terminal receiving the second configuration information, and determining a second sensing resource based on the second configuration information.

Before introducing the embodiments, some terms involved in this application are explained.

[0087] To facilitate understanding of the technical solutions of the embodiments of this application, a brief introduction to the relevant technologies of this application is given below.

[0088] 1. Quasi-colocation (QCL) relationship:

[0089] QCL relationships are used to indicate that multiple resources have one or more identical or similar communication characteristics. For multiple resources with quasi-colocation relationships, the same or similar communication configurations can be used.

[0090] For example, signals carried on resources with a QCL relationship have the same or similar parameters; or, the parameters of one resource (also called QCL parameters) can be used to determine the parameters of another resource with a QCL relationship; or, the two resources have the same parameters; or, the parameter difference between the two resources is less than a certain threshold. The parameters may include one or more of the following: delay spread, Doppler spread, Doppler shift, average delay, average gain, spatial Rx parameters, etc. The spatial Rx parameters may include one or more of the following: angle of arrival (AOA), average AOA, AOA spread, angle of departure (AOD), average departure angle AOD, AOD spread, receive antenna spatial correlation parameters, transmit antenna spatial correlation parameters, transmit beam, receive beam, and resource identifier.

[0091] In the NR system, QCL relationships can be categorized into the following four types based on different parameters:

[0092] Type A: Doppler frequency shift, Doppler spread, average time delay, time delay spread;

[0093] Type B: Doppler frequency shift, Doppler spread;

[0094] Type C: Doppler frequency shift, average time delay;

[0095] Type D: Space reception parameters.

[0096] QCLs of type D are used to indicate beams, that is, QCLs defined based on spatial reception parameters. Resources with the QCLtypeD relationship have beams with the same spatial characteristics and can be received using the same receiving beam.

[0097] In communication protocols, beamforming can be manifested as a spatial domain filter, spatial parameter, spatial setting, QCL information, QCL assumption, QCL indication, etc. Beamforming can be indicated through Transmission Configuration Indicator (TCI) state parameters, spatial relation parameters, or by identifying various resources, such as resource indices for Channel State Information Reference Signals (CSI-RS), Synchronous Signal / Physical Broadcast Channel Blocks (SS / PBCH blocks or SSBs), and Sounding Reference Signals (SRS).

[0098] 2. Wireless communication:

[0099] In wireless communication systems, communication can be categorized into different types based on the type of transmitter and receiver. For example, sending information from a network device or base station (BS) to a terminal or user equipment (UE) is typically called downlink (DL) communication, while sending information from a terminal to a network device is called uplink (UL) communication.

[0100] In Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A), and New Radio (NR) systems, based on the different duplex modes, they can be mainly divided into Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes. For wireless communication systems operating in TDD mode, the downlink and uplink carriers share the same carrier frequency.

[0101] 3. Wireless sensing, sensing signals:

[0102] The technical principles of wireless sensing differ somewhat from those of wireless communication. For example, in wireless communication, the transmitting end modulates information onto radio waves and sends it to the receiving end, which then demodulates the signal carried on the radio waves to obtain the information. In a sensing scenario, the transmitting device radiates electromagnetic waves into the surrounding environment to send sensing signals. The receiving device receives the sensing signals reflected from the surrounding environment and analyzes and compares them with the transmitted sensing signals to perceive relevant information about the surrounding environment, such as the presence of the target, the number of targets, and the location of each target. For instance, the reflected sensing signals can also be called echo signals or echoes of sensing signals; these terms are interchangeable and not limited to one another.

[0103] A sensing signal can be understood as a signal used to sense (or detect) a target. The target can also be understood as a target object, such as a scatterer or reflector. The sensing signal can be a detection signal, a linear frequency modulated signal, a radar signal, a radar sensing signal, a radar detection signal, an environmental sensing signal, a pulse signal, or a signal in a wireless communication system. The sensing signal can be a reference signal; for example, its initial amplitude and phase information can be pre-configured to the receiver through a configuration sequence. The sensing signal can also be a data signal; the receiver can calculate the initial amplitude and phase of each data signal using known modulation methods such as data verification. The sensing signal can also have other names, which are not specifically limited in this application.

[0104] Generally, sensing can be categorized into single-site sensing and dual-site sensing modes. In single-site sensing mode, the transmitting and receiving ends of the sensing signal are the same device. In terms of the sensing process, this station must both transmit and receive the reflected signals from the target surface; therefore, single-site sensing mode can also be called a self-transmitting and self-receiving module.

[0105] In dual-station sensing mode, the transmitting and receiving ends of the sensing signals are two different devices. From the sensing process perspective, station A transmits the sensing signal, and the reflected signal from the target surface is received by station B. Therefore, dual-station sensing mode can also be called self-transmitting and other-receiving or A-transmitting and B-receiving mode.

[0106] 4. Integrated communication and sensing:

[0107] In the evolution of fifth-generation (5G) wireless communication technology towards 5G-Advanced (5G-A) and future communication technologies, integrated communication and sensing technology is considered one of the key technologies for expanding the service capabilities of mobile communication networks. The core idea of ​​this technology is to add sensing capabilities to the mobile communication network, building capabilities such as target detection, imaging, and identification, thereby integrating communication and sensing capabilities into a single network to achieve harmonious coexistence and even mutual benefit.

[0108] For example, in integrated communication and sensing technology, the sensing mode can include... Figure 1 The six sensing scenarios are shown. Among them, sensing scenarios (1) and (4) are single-site sensing modes. In sensing scenario (1), the base station transmits and receives data automatically, and in sensing scenario (4), the terminal transmits and receives data automatically. Sensing scenarios (2), (3), (5), and (6) are dual-site sensing modes. In sensing scenario (2), base station A transmits data and base station B receives data. In sensing scenario (3), the base station transmits data and the terminal receives data. In sensing scenario (5), the terminal transmits data and the base station receives data. In sensing scenario (6), terminal A transmits data and terminal B receives data. Among them, sensing scenarios (3)-(6) can also be called UE-assisted sensing scenarios.

[0109] Furthermore, in an integrated communication and sensing system, the base station has the ability to communicate with terminals and also possesses sensing capabilities. For example, such as... Figure 2 As shown in (a), the base station can communicate with the terminal and can perform self-transmitting and self-receiving sensing, such as sending sensing signals and receiving echo signals; or, as... Figure 2 As shown in (b), base station A can communicate with the terminal and can perform self-transmitting and receiving sensing, such as sending sensing signals and having base station B receive the echo signals.

[0110] In traditional radar sensing, the maximum speed that radar can detect is fixed. If the target's speed exceeds the maximum detection speed, speed measurement ambiguity will occur, leading to errors in the perceived target speed.

[0111] For example, such as Figure 3 As shown, taking a sensing signal consisting of 5 pulses within a coherent processing interval (CPI), with the interval between pulses being the pulse repetition interval (PRI), according to the Nyquist criterion, the distortion-free sampling frequency must be greater than twice the signal frequency, i.e.:

[0112]

[0113] Among them, fs f represents the sampling frequency. D λ represents the Doppler frequency, v represents the sensing speed (i.e., the speed at which large targets can be sensed), λ represents the wavelength (λ = c / carrier frequency), and c represents the speed of light.

[0114] From the above relationships, it can be seen that the maximum sensing speed is determined by both wavelength and PRI. The denser the sensing symbols and the smaller the PRI, the larger the sensing speed range. For example, taking a carrier frequency of 26 GHz, a subcarrier spacing of 120 kHz, and a PRI of one time slot as an example, the unambiguous sensing speed range can be obtained as -23 to 23 m / s. Under this configuration, if the speed of the target being sensed is 25 m / s, the sensed speed will be 2 m / s, that is, speed ambiguity occurs.

[0115] Currently, in integrated communication and sensing solutions, base stations typically configure sensing-related settings for terminals, such as configuring the sequence for generating sensing signals and the time-frequency location of the sensing signals. Subsequently, the base station transmits sensing signals according to the configured time-frequency resources, and the terminal receives the sensing signals reflected from the target on those time-frequency resources to perform sensing.

[0116] However, similar to radar sensing, when sensing resources are fixed, the maximum sensing speed is also fixed. That is, the maximum speed of a target that can be sensed is fixed. In this case, if the target's movement exceeds the maximum sensing speed, velocity ambiguity will occur, leading to errors in the sensed target speed.

[0117] Based on this, this application provides a sensing method in which the interval between adjacent time units in the sensing resources used to carry the sensing signal can be set to a larger interval. Subsequently, the interval between adjacent time units can be adjusted to a smaller interval, thereby expanding the sensing speed range and realizing flexible adjustment of the sensing speed range. This allows for the identification of speed measurement ambiguity through different sensing speed ranges, thus improving sensing performance. Furthermore, compared to continuously sending sensing signals at smaller time unit intervals, the overhead of sensing resources can be reduced.

[0118] The technical solutions of this application embodiment can be used in various communication systems, including third-generation partnership project (3GPP) communication systems, such as fourth-generation (4G) systems like Long Term Evolution (LTE), fifth-generation (5G) systems like New Radio (NR), LTE and 5G hybrid networking systems, sensing systems, integrated communication and sensing systems, non-terrestrial networks (NTN), device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, machine-type communication (MTC) systems, Internet of Things (IoT) systems, or other future communication systems. The communication system can also be a non-3GPP communication system; there is no limitation on this.

[0119] The communication systems described above are merely illustrative examples, and are not limited to those described herein. The communication systems provided in this application do not impose any limitations on the solutions described herein. This will be explained uniformly here and will not be repeated below.

[0120] Figure 4 A possible, non-limiting system schematic diagram is shown. For example... Figure 4 As shown, the communication system 40 includes a radio access network (RAN) 400. Optionally, it may also include a core network (CN) 500 and / or the Internet. Figure 4 (Not shown in the image). RAN 400 includes at least one RAN node (e.g., ...). Figure 4 410a and 410b (collectively referred to as 410) and at least one terminal (such as Figure 4 The 420a-420j in the core network are collectively referred to as 420. The core network 500 includes at least one core network device.

[0121] Optionally, RAN 400 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 4(Not shown in the image). Terminal 420 connects to RAN node 410 wirelessly (e.g., via air interface communication). RAN node 410 connects to core network 500 wirelessly or via wired connection. The core network equipment in core network 500 and RAN node 410 in RAN 400 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0122] In one possible implementation, RAN 400 can be a 3GPP-related cellular system, such as a 4G or 5G mobile communication system, an NTN system (e.g., an NTN supporting pass-through mode and / or regenerative mode, or an NTN supporting eye-fixed cell mode and / or eye-moving cell mode), or a future-oriented evolution system. RAN 400 can also be an open RAN (O-RAN or ORAN), a cloud radioaccess network (CRAN), or a wireless fidelity (WiFi) system. RAN 400 can also be a communication system integrating two or more of the above systems.

[0123] In some scenarios, the roles of RAN node 410 and terminal 420 are relative, for example, Figure 4 Network element 420i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminal 420j accessing RAN 400 via network element 420i, network element 420i is a base station; however, for base station 410a, network element 420i is a terminal. RAN node 410 and terminal 420 are sometimes referred to as communication devices, for example... Figure 4 Network elements 410a and 410b can be understood as communication devices with base station functions, while network elements 420a-420j can be understood as communication devices with terminal functions.

[0124] In one possible implementation, RAN node 410 is a network-side device with wireless transceiver capabilities. RAN nodes, sometimes also referred to as RAN entities or access nodes, constitute part of the communication system and are used to assist terminals in achieving wireless access. Multiple RAN nodes 410 in the communication system 40 can be of the same type or different types.

[0125] As one possible implementation, RAN node 410 can be an access network device, such as a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a base station evolved by 3GPP, a base station in a future mobile communication system, an access node in a WiFi system, a wireless relay node, a wireless backhaul node, etc.

[0126] For example, a RAN node can be a macro base station (such as...) Figure 4 410a), micro base stations or indoor stations (such as Figure 4 RAN nodes can be 410b, relay nodes or donor nodes, or wireless controllers in CRAN scenarios. Optionally, RAN nodes can also be servers, wearable devices, vehicles or in-vehicle equipment, etc. For example, in V2X technology, the RAN node can be a roadside unit (RSU).

[0127] As another possible implementation, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, with different RAN nodes each implementing some of the functions of the access network equipment. For example, RAN nodes can be central units (CU), distributed units (DU), CU-control plane (CP), CU-user plane (UP), radio units (RU), or sensing units (SU), etc.

[0128] For example, the CU and DU can be configured separately or included in the same network element, such as in the baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0129] Optionally, the CU can be connected to the core network and one or more DUs. The CU may have some of the core network's functions. Furthermore, access network equipment may include one or more CUs, one or more DUs, and one or more RUs.

[0130] For example, the CU can be used to perform layer 2 (L2) and layer 3 (L3) functions. Furthermore, the CU can also have some of the core network functions. The DU can be used to perform layer 1 (L1) and some L2 functions, and the RU can be used to perform L1 computing and radio frequency (RF) digital functions.

[0131] like Figure 5 As shown, a CU can connect to the core network and one or more DUs. A backhaul interface exists between the CU and the core network to carry traffic between them. A midhaul interface exists between the CU and the DU to carry traffic between them. A DU can connect to one or more RUs. A fronthaul interface exists between the DU and the RU to carry traffic between them.

[0132] In terms of hardware, CU and DU can include a chassis platform, motherboard, peripheral devices, and cooling equipment. The motherboard contains processing units, memory, internal input / output (I / O) interfaces, and external connection ports. Its hardware accelerator is designed with interfaces, and hardware functional components include: storage for software, hardware, and system debugging interfaces, and a single-board management controller.

[0133] DUs are typically implemented using multi-core processors and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on a multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to a field-programmable gate array (FPGA) / graphics processing unit (GPU)-based hardware accelerator; or all L1 functions can be offloaded to an FPGA / GPU-based hardware accelerator, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. Hardware accelerators support interconnection with x86 or non-x86 processors. Similarly, accelerators have a multi-channel peripheral component interconnect express (PCIe) interface pointing to the central processing unit (CPU) and external connections via GbE.

[0134] An RU may include an O-RAN processing unit (OPU), a digital processing unit (DPU), and an RF processing unit.

[0135] The OPU is used to receive Enhanced Common Public Radio Interface (eCPRI) frames from the O-RAN fronthaul and perform fronthaul interface, L1 layer (coding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or application-specific integrated circuit (ASIC).

[0136] The DPU is used to perform synchronization, uplink (UL) digital downconversion (DDC), downlink (DL) digital upconversion (DUC), channel failure ratio (CFR), and digital pre-distortion (DPD) processing. It improves power amplifier efficiency by reducing the peak-to-average power ratio (PAPR) / adjacent channel leakage ratio (ACLR) of the RF front-end. The DPU can be implemented as an FPGA or ASIC.

[0137] The RF processing unit includes a transceiver module, up / down converters, power amplifiers (PA), low-noise amplifiers (LNA), and Tx / Rx filters. Analog-to-digital conversions (such as digital-to-analog converters (DACs), analog-to-digital converters (ADCs), RF sampling, and frequency conversion) can be performed within the transceiver module. Note that physical and logical partitions within the RF processing unit do not require specific boundaries.

[0138] 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 O-RAN central unit (O-CU), DU can also be called an O-RAN distributed unit (O-DU), CU-CP can also be called an O-RAN central unit control plane (O-CU-CP), CU-UP can also be called an O-RAN central unit user plane (O-CU-UP), and RU can also be called an O-RAN radio unit (O-RU).

[0139] As another possible implementation, the RAN node can also be a non-real time RAN intelligent controller (Non-RT RIC or NRT RIC) and / or a near-real time RAN intelligent controller (Near-RT RIC or nRT RIC).

[0140] Non-RT RIC is used to implement non-real-time intelligent management of the RAN, enabling artificial intelligence (AI) / machine learning (ML) for model training and updates, and guiding applications / functions within the Near-RT RIC based on policies. Near-RT RIC is used to implement near real-time intelligent management of the RAN, achieving near real-time control and optimization of O-RAN modules and resources through data collection and related operations on the E2 interface. The E2 interface can be understood as an open interface between two nodes (or endpoints).

[0141] All or part of the functions of the RAN node in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform), or through software modules, hardware modules, or a combination of software and hardware modules. The RAN node in this application can also be a logical node, logical module, or software capable of implementing all or part of the functions of the access network equipment, or a device with some access network equipment functions, such as a chip system, which can be installed in the access network equipment.

[0142] In one possible implementation, the core network equipment can refer to the equipment in the core network 500 that provides service support to the terminal. In this embodiment, the core network equipment in the core network 500 includes sensing function (SF) network elements. The SF network elements are primarily responsible for sensing services and are used to implement sensing functions. Sensing functions include, for example, sensing control functions and / or sensing computing functions. Furthermore, the SF network elements can also support sensing billing functions when the terminal and / or RAN node perform sensing.

[0143] In one possible scenario, the functionality of the SF network element can be implemented by the network data analytics function (NWDAF) network element, or the SF network element and the NWDAF network element can be co-located. Alternatively, the SF network element can be deployed integrated with the core network or deployed independently.

[0144] In one possible implementation, terminal 420 is a user-side device with wireless transceiver capabilities. It can be a fixed device, mobile device, handheld device (e.g., mobile phone), wearable device, in-vehicle device, or a wireless device (e.g., communication module, modem, or chip system, etc.) built into the aforementioned devices. The terminal is used to connect people, objects, and machines, and can be widely used in various scenarios, such as: cellular communication, device-to-device (D2D) communication, V2X communication, MTC communication, IoT, virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, drones, robots, etc. For example, a terminal can be a handheld terminal in cellular communication, a communication device in D2D, an IoT device in MTC, a surveillance camera in intelligent transportation and smart cities, or a communication device on a drone; or, a terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the device form of the terminal. A terminal may sometimes be referred to as a UE, user terminal, user device, user unit, user station, terminal, access terminal, access station, UE station, remote station, mobile device, or wireless communication device, etc.

[0145] In one possible implementation, RAN node 410 has both wireless communication and sensing capabilities. Terminal 420 has wireless communication capabilities; furthermore, some terminals may have sensing capabilities. For example, as... Figure 6 As shown, the RAN node can communicate wirelessly and sense with terminal 1 and terminal 3, and communicate with terminal 2. Furthermore, the RAN node can also perform self-transmitting and self-receiving sensing to perceive its surrounding environment.

[0146] It should be noted that the system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0147] The following is combined Figure 4 The communication system shown here, taking the interaction between the RAN node and the terminal as an example, describes the communication method provided in the embodiments of this application. It should be noted that in the following embodiments of this application, the message names, parameter names, or information names between the RAN node and the terminal are just examples, and other names may be used in other embodiments. The method provided in this application is not specifically limited in this regard.

[0148] It is understood that in the embodiments of this application, the RAN node or terminal may execute some or all of the steps in the embodiments of this application. These steps or operations are merely examples, and the embodiments of this application may also perform other operations or variations thereof. Furthermore, the various steps may be executed in different orders as presented in the embodiments of this application, and it is not necessarily necessary to execute all the operations in the embodiments of this application.

[0149] It is understood that this application uses RAN nodes and terminals as examples to illustrate the execution of the interaction, but this application does not limit the execution subject of the interaction. For example, the method executed by the RAN node in this application can also be executed by a module (e.g., a chip, chip system, or processor) applied to the RAN node, or by a logical node, logical module, or software that can implement all or part of the RAN node's functions; similarly, the method executed by the terminal in this application can also be executed by a module (e.g., a chip, chip system, or processor) applied to the terminal, or by a logical node, logical module, or software that can implement all or part of the terminal's functions.

[0150] The perception provided by the embodiments of this application will be described below. For example... Figure 7 As shown, the sensing method may include the following steps:

[0151] S701, the RAN node determines the first sensing resource. The time unit interval of the first sensing resource is the first interval.

[0152] As one possible implementation, in this embodiment, the sensing resource is used to carry sensing signals. The sensing resource includes at least one time unit. When the sensing resource includes multiple time units, these multiple time units are discontinuous in the time domain. The interval between adjacent time units in the sensing resource is equal. The interval between adjacent time units in the sensing resource can be understood as the time unit interval of the sensing resource. That is, the interval between adjacent time units in the first sensing resource is the first interval.

[0153] For example, the interval between adjacent time units can be understood as: the difference in the index of adjacent time units, the number of time units between adjacent time units, the interval between the start position of the previous time unit and the start position of the next time unit in adjacent time units, the interval between the end position of the previous time unit and the end position of the next time unit in adjacent time units, etc.

[0154] For example, a time unit can be an orthogonal frequency division multiplexing (OFDM) symbol, slot, microslot, subframe, frame, etc., without limitation. An OFDM symbol can be understood as the smallest time unit in the time domain of an OFDM system. In one possible interpretation, during the evolution of 5G-A and future communication technologies, the time unit in this application can also be understood as the smallest time unit under the corresponding communication system or communication standard.

[0155] For example, taking OFDM symbols as the time unit, in the case of DDDSU frame structure in a TDD system, one possible distribution of the first sensing resource can be as follows: Figure 8 As shown. Where D represents the downlink time slot, U represents the uplink time slot, and S represents the mixed uplink / downlink time slot and guard slot. See also... Figure 8 The first sensing resource includes OFDM symbol 6 in the first and third downlink time slots, with an interval of two time slots (i.e., the first interval), or 14 OFDM symbols. The other OFDM symbols in the first and third downlink time slots, as well as the second downlink time slot, can be used for downlink communication between RAN nodes and terminals; OFDM symbols 0-9 in time slot S can be used for downlink transmission, OFDM symbols 10-11 are used as a guard interval, and OFDM symbols 12-13 are used for uplink communication; OFDM symbols in time slot U are used for uplink communication.

[0156] As one possible implementation, the first sensing resource and the first reference resource have a QCL relationship, such as a QCLtypeD relationship. That is, the beams corresponding to the first sensing resource and the first reference resource have the same spatial characteristics, or in other words, they correspond to the same beam. For ease of explanation, the beams corresponding to the first sensing resource and the first reference resource in the following embodiments of this application are referred to as the first beam.

[0157] For example, the first reference resource can be a reference signal resource, such as a CSI-RS resource, SSB resource, SRS resource, etc. Alternatively, the first reference resource can also be a downlink channel resource, such as a physical downlink control channel (PDCCH) resource, etc., without limitation.

[0158] For example, the first beam is a portion of the beam transmitted by the RAN node. The area covered by the first beam can be understood as the perceived region of interest. The determination of the first beam and related implementations will be described in detail in subsequent embodiments, and will not be repeated here.

[0159] S702, RAN node determines the second sensing resource.

[0160] The time unit interval of the second sensing resource is the second interval, that is, the interval between adjacent time units in the second sensing resource is the second interval. The second interval is smaller than the first interval.

[0161] As one possible implementation, the second sensing resource and the first sensing resource can have the same parameters except for the time unit interval. For example, the relative starting positions of the first and second sensing resources are the same, such as the first time unit of both being located in OFDM symbol 6 of the downlink time slot; or the duration of the first and second sensing resources is the same, which can be understood as the time between the first and last time units in the sensing resource, and the duration can also be understood as CPI; or the frequency domain resources of the first and second sensing resources are the same; or the time domain periods of the first and second sensing resources are the same.

[0162] For example, taking OFDM symbols as the time unit, in the case of DDDSU frame structure in a TDD system, one possible distribution of the second sensing resources can be as follows: Figure 9 As shown in (a) above. Where D represents the downlink time slot, U represents the uplink time slot, and S represents the mixed uplink / downlink time slot and guard slot. See also... Figure 9In (a), the second sensing resource includes OFDM symbol 6 and OFDM symbol 13 in the first two downlink time slots, and OFDM symbol 6 in the third downlink time slot, wherein the interval between adjacent OFDM symbols (i.e., the second interval) is 7 OFDM symbols. The other OFDM symbols in the three downlink time slots can be used for downlink communication. OFDM symbols 0-9 in time slot S can be used for downlink transmission, OFDM symbols 10-11 are used as a guard interval, and OFDM symbols 12-13 are used for uplink communication; OFDM symbols in time slot U are used for uplink communication.

[0163] As another possible implementation, the second sensing resource and the first sensing resource can differ in parameters other than the time unit interval. For example, the durations of the first sensing resource and the second sensing resource can be different, such as... Figure 9 As shown in (b), the second sensing resource may include OFDM symbol 6 and OFDM symbol 13 in three downlink time slots, and OFDM symbol 6 in time slot S. At this time, compared to Figure 8 The first sensory resource shown is Figure 9 The second sensing resource shown in (b) has a longer duration. Furthermore, other parameters of the second and first sensing resources, such as frequency domain resources, may differ, but this application does not specifically limit this.

[0164] As one possible implementation, the second sensing resource and the first reference resource have a QCL relationship. If the first sensing resource and the first reference resource also have a QCL relationship, it can be assumed that the second sensing resource and the first sensing resource correspond to the same beam; that is, the second sensing resource also corresponds to the first beam.

[0165] When both the second sensing resource and the first sensing resource have a QCL relationship with the first reference resource, it can be assumed that for the same beam, or the same beam direction, or the same coverage area, or the same sensing space, sensing resources can be configured with larger time unit intervals and smaller time unit intervals, respectively.

[0166] Of course, the reference resource that has a QCL relationship with the second sensing resource does not have to be the first reference resource. For example, it can be the second reference resource, that is, a reference resource that has a QCL relationship with the second sensing resource, and is different from the reference resource that has a QCL relationship with the first sensing resource. This application does not make specific limitations in this regard.

[0167] As one possible implementation, the resource identifier of the second sensing resource is the same as that of the first sensing resource. In this case, the second sensing resource and the first sensing resource can be understood as the same resource, or they can be understood as different resources. Alternatively, the resource identifier of the second sensing resource can be different from that of the first sensing resource. In this case, the second sensing resource and the first sensing resource can be understood as different resources. This application does not make any specific limitations on this.

[0168] As one possible implementation, the second sensing resource can be understood as an updated first sensing resource. For example, the RAN node updates the time unit interval of the first sensing resource from the first interval to the second interval to obtain the second sensing resource, or obtains the updated first sensing resource.

[0169] It should be noted that there is no strict order between the above steps S701 and S702. Step S701 can be executed first, followed by step S702; or step S702 can be executed first, followed by step S701; or steps S701 and S702 can be executed simultaneously. This application does not impose any specific restrictions on this.

[0170] S703, RAN nodes send sensing signals on the second sensing resource.

[0171] Optionally, the RAN node may also transmit sensing signals on the first sensing resource. For ease of description, in the following embodiments of this application, the sensing signal transmitted on the first sensing resource will be referred to as the first sensing signal, and the sensing signal transmitted on the second sensing resource will be referred to as the second sensing signal.

[0172] In other words, the RAN node acts as the transmitter of the sensing signal. The receiver of the sensing signal can be this RAN node, meaning the RAN node performs self-transmission and self-reception; alternatively, the receiver of the sensing signal can be a terminal or another RAN node. This application does not specifically limit this, meaning step S703 may also include: the RAN node / terminal / other RAN node receiving the second sensing signal on the second sensing resource. Furthermore, the RAN node / terminal / other RAN node also receives the first sensing signal on the first sensing resource. Figure 7 The following explanation uses the receiving end of the sensing signal as an example.

[0173] As is understandable, the receiving end of the sensing signal receives the signal formed after the sensing signal sent by the RAN node is reflected by targets in the surrounding environment. For ease of description, this embodiment uses the receiving end receiving the sensing signal as an example.

[0174] As one possible implementation, when the first and second sensing resources are periodic resources, the first and second sensing resources can be distributed alternately in the time domain, or there can be a first sensing resource between two adjacent second sensing resources, or there can be a second sensing resource between two adjacent first sensing resources.

[0175] For example, the coherent processing time with an odd index includes the first sensing resource, and the coherent processing time with an even index includes the second sensing resource. For instance, the first sensing resource is configured in the first coherent processing time, the second sensing resource is configured in the second coherent processing time, the first sensing resource is configured in the third coherent processing time, the second sensing resource is configured in the fourth coherent processing time, and so on. Accordingly, during the coherent processing time with an odd index, the RAN node transmits the first sensing signal on the first sensing resource, and during the coherent processing time with an even index, the RAN node transmits the second sensing signal on the second sensing resource.

[0176] As another possible implementation, multiple first sensing resources can exist between two adjacent second sensing resources. For example, first sensing resources can be configured during the first and second coherent processing times, second sensing resources can be configured during the third coherent processing time, first sensing resources can be configured during the fourth and fifth coherent processing times, second sensing resources can be configured during the sixth coherent processing time, and so on. Correspondingly, during the first, second, fourth, fifth… coherent processing times, the RAN node transmits first sensing signals on the first sensing resources, and during the third, sixth, ninth… coherent processing times, the RAN node transmits second sensing signals on the second sensing resources.

[0177] The above example illustrates the situation where there are two first sensing resources between two adjacent second sensing resources. In addition, there may be other numbers of first sensing resources between two adjacent second sensing resources, such as three or four first sensing resources, without any limitation.

[0178] Based on this scheme, the interval between adjacent time units in the sensing resources used to carry the sensing signal can be initially set to a larger interval. Subsequently, the interval between adjacent time units of the sensing resources can be adjusted to a smaller interval. Compared with before adjusting the time unit interval, the sensing speed range can be expanded, thereby achieving flexible adjustment of the sensing speed range. This allows for the identification of speed measurement ambiguity through different sensing speed ranges and accurate perception of the target's actual speed, solving the problem of speed measurement ambiguity and improving sensing performance. Furthermore, compared to always configuring a small time unit interval for the sensing resources, i.e., always configuring a high density of sensing resources, the scheme of this application initially configures a larger time unit interval for the sensing resources, thus saving the overhead of sensing resources and avoiding the occupation of large amounts of time-frequency resources, which could lead to a decrease in communication performance. In other words, it can reduce the impact of sensing on communication.

[0179] In one possible implementation, when the receiving end of the sensing signal is a terminal or another RAN node, the RAN node needs to send configuration information to the receiving end to configure the sensing resources. For example, the RAN node can configure the sensing resources in three ways, which will be explained below using a terminal as the receiving end.

[0180] Method 1: The RAN node sends first configuration information and second configuration information to the terminal. Correspondingly, the terminal receives the first and second configuration information from the RAN node.

[0181] The first configuration information is used to configure at least one sensing resource. This at least one sensing resource includes a first sensing resource. The time units included in each of these at least one sensing resources are located at different positions. Each sensing resource configured in the first configuration information has a QCL relationship with a reference resource. That is, each sensing resource is associated with one beam. For example, if a RAN node can transmit 32 beams, the first configuration information configures 32 sensing resources, each associated with one of the 32 beams of the RAN node.

[0182] As one possible implementation, the first configuration information can be carried in a radio resource control (RRC) message, such as an RRC reconfiguration message.

[0183] As one possible implementation, after sending the first configuration information, the RAN node can transmit sensing signals on at least one sensing resource configured in the first configuration information. Correspondingly, after receiving the first configuration information, the terminal can determine at least one sensing resource, including the first sensing resource, based on the first configuration information. Furthermore, the terminal can receive sensing signals on this at least one sensing resource.

[0184] As one possible implementation, the RAN node can send the second configuration information to the terminal after sending the first configuration information.

[0185] Wherein, the second configuration information is used to update the time unit interval of the first sensing resource among the at least one sensing resource to the second interval; or, the second configuration information is used to update the time unit interval of some or all of the sensing resources that have a QCL relationship with the first reference resource among the at least one sensing resources to the second interval, wherein the some or all of the sensing resources that have a QCL relationship with the first reference resource include the first sensing resource.

[0186] Accordingly, after receiving the second configuration information, the terminal can determine the second sensing resource based on the second configuration information. For example, it can update the interval of the first sensing resource to the second interval based on the second configuration information to obtain the second sensing resource. Similarly, the RAN node also updates the interval of the first sensing resource to the second interval to obtain the second sensing resource.

[0187] As one possible implementation, the second configuration information may include first indication information and second indication information. The first indication information indicates a first sensing resource, and the second indication information indicates a second interval.

[0188] For example, the first indication information may include the resource identifier of the first sensing resource. In this case, the second configuration information can be considered as being used to update the time unit interval of the portion of the sensing resources (i.e., the first sensing resource) that has a QCL relationship with the first reference resource to the second interval.

[0189] Alternatively, the first indication information may include the identifier of the first reference resource. In this case, the second configuration information can be considered as being used to update the time unit intervals of all sensing resources that have a QCL relationship with the first reference resource among at least one sensing resource to the second interval. For example, if both the first sensing resource and the third sensing resource have a QCL relationship with the first reference resource among the at least one sensing resource, then the time unit intervals of both the first sensing resource and the third sensing resource need to be updated to the second interval.

[0190] Optionally, the first indication information may further include the resource identifier of the second sensing resource. In this case, the resource identifier of the second sensing resource can be understood as the updated resource identifier of the first sensing resource. Alternatively, the first indication information may not include the identifier of the second sensing resource; in this case, the resource identifier of the second sensing resource and the resource identifier of the first sensing resource can be considered to be the same.

[0191] Based on this possible implementation, when the first indication information includes the resource identifier of the first sensing resource, it can accurately indicate the sensing resource that needs to be updated. When the first indication information includes the resource identifier of the first reference resource, it can indicate one or more sensing resources with a QCL relationship with it to be updated based on a resource identifier. When there are multiple sensing resources with a QCL relationship with the first reference resource, signaling overhead can be saved compared to indicating the resource identifiers of each of the multiple sensing resources one by one.

[0192] For example, the second indication information may include the ratio of the second interval to the first interval. For instance, the second indication information may be carried by 2 bits, each value of which may correspond to a ratio of the second interval to the first interval. The correspondence between the values ​​of the 2 bits and the ratio of the second interval to the first interval may be shown in Table 1.

[0193] Table 1

[0194] Bit value The ratio of the second interval to the first interval meaning 00 1 / 2 The time unit interval is updated to 1 / 2 of the original. 01 1 / 4 The time unit interval is updated to 1 / 4 of the original. 10 1 / 8 The time unit interval is updated to 1 / 8 of the original. 11 1 / 16 The time unit interval has been updated to 1 / 16 of its original value.

[0195] Alternatively, the second indication information may include a second interval. For example, the second indication information may be carried by multiple bits, the values ​​of which are the values ​​of the second interval.

[0196] Based on this possible implementation, when the second indication information includes the ratio of the second interval to the first interval, the second interval can be indicated with fewer bits, thereby saving signaling overhead. For example, when the first interval is 14 OFDM symbols and the second interval is 7 OFDM symbols, if the second interval is indicated by the bit values ​​carrying the second indication information, three bits are required, for example, these three bits are set to "111". If the second interval is indicated by the correspondence shown in Table 1 above, only two bits are required. When the second indication information includes the second interval, the second interval can be indicated flexibly, improving the flexibility of indicating the second interval.

[0197] As one possible implementation, the second indication information indicates the implementation of the second interval, which can be referred to the implementation of the dl-PRS-Periodicity-and-ResourceSetSlotOffset field in the positioning reference signal (PRS) configuration, and / or the implementation of the CSI-ResourcePeriodicityAndOffset field in the CSI-RS configuration, which will not be elaborated here.

[0198] As one possible implementation, the second configuration information can be carried in the downlink control information (DCI). Based on this implementation, compared to reconfiguring sensing resources with smaller time unit intervals via RRC messages, the effective latency of the second sensing resources can be reduced, allowing the second sensing resources to take effect as soon as possible. This is because reconfiguration based on RRC messages has a certain reconfiguration delay, and the update of the time unit interval of the sensing resources cannot take effect immediately.

[0199] In one possible implementation, the RAN node can send the second configuration information in the following three scenarios:

[0200] Scenario 1: The sensing network element sends a third indication message to the RAN node. Correspondingly, the RAN node receives the third indication message from the sensing network element and, based on the third indication message, sends the second configuration information.

[0201] The third indication information specifies the time unit interval for updating sensing resources that have a QCL relationship with the first reference resource. In other words, the RAN node sends the second configuration information based on the triggering or indication from the sensing network element.

[0202] As one possible implementation, when a RAN node transmits a sensing signal on at least one sensing resource configured in the first configuration information, the receiving end of the sensing signal can report the sensing results obtained based on the sensing signal to the sensing network element. The sensing results may include, for example, the location of the sensing target, the speed of the sensing target, and the type of the sensing target (such as buildings, pedestrians, vehicles, etc.) corresponding to each sensing resource.

[0203] After receiving the sensing results, the sensing network element can analyze them. Furthermore, it can also perform fusion analysis by combining the sensing results reported by other devices or historical sensing results.

[0204] If the sensing network element determines, based on analysis, that the upper limit of the target's movement speed is fixed within the coverage area of ​​the first beam corresponding to the first sensing resource, for example, if the maximum movement speed of the target within the coverage area of ​​the first beam is 40m / s for a long period of time, then the sensing network element can infer that speed measurement ambiguity may have occurred, and thus send a third indication message to the RAN node to instruct the RAN node to send a second configuration message.

[0205] Alternatively, the sensing network element can know in advance the range of target movement speeds within the coverage area of ​​the first beam, for example, based on a sensing map. If the sensing result reported by the receiver indicates that the target movement speed within the coverage area of ​​the first beam is not within that speed range, or is close to the minimum speed within that range, the sensing network element can infer that speed measurement ambiguity may have occurred, and thus send third indication information to the RAN node to instruct the RAN node to send second configuration information.

[0206] Alternatively, the sensing network element can continuously monitor the velocity of a target within the coverage area of ​​the first beam based on analysis. If the sensing network element detects a jump in the velocity of the target within a certain coherent time interval, it can infer that velocity measurement ambiguity may have occurred, and thus send a third indication message to the RAN node.

[0207] For example, suppose the sensing network element analyzes and obtains the following characteristics of the velocity of a sensed target: the velocity is 9 m / s in the first coherent time interval, 10 m / s in the second coherent time interval, and 1 m / s in the third coherent time interval. That is, the velocity of the target changes abruptly within the three coherent time intervals. Then the sensing network element can determine that velocity ambiguity may have occurred. If no velocity ambiguity has occurred, the velocity of the target in the third coherent time interval might be 12 m / s.

[0208] As one possible implementation, the third indication information may include at least one of the following: the resource identifier of the first sensing resource, the resource identifier of the first reference resource, the second interval, the maximum sensing speed, or the sensing requirement.

[0209] For example, if the third indication information includes the resource identifier of the first sensing resource, the first indication information may include either the resource identifier of the first sensing resource or the resource identifier of the first reference resource. If the third indication information includes the resource identifier of the first reference resource, the first indication information may include the resource identifier of the first reference resource. If the third indication information includes the maximum sensing speed or sensing requirement, the RAN node can determine the second interval based on the maximum sensing speed or sensing requirement, thereby indicating the second interval through the second indication information.

[0210] Scenario 2: The RAN node sends second configuration information based on prior information. This prior information can indicate the type of area covered by each beam of the RAN node.

[0211] For example, such as Figure 10 As shown, the prior information acquired by the RAN node can instruct RAN node beams #0 and #1 to cover buildings, and beams #2 and #3 to cover roads. Based on Figure 10The example shown shows that the first configuration information configuration can configure 4 sensing resources, which are associated with beam #0, beam #1, beam #2 and beam #3 respectively.

[0212] As one possible implementation, this prior information could be obtained by the RAN node based on relevant engineering parameters during RAN node deployment. Alternatively, it could be determined by the RAN node after beam scanning, using the results of the beam scan. Alternatively, the RAN node could acquire sensing results and determine the prior information based on those results.

[0213] For example, the sensing result is obtained based on the sensing signal carried on at least one sensing resource configured with the first configuration information. For instance, the RAN node can transmit the sensing signal on at least one sensing resource configured with the first configuration information, and the receiving end can receive the sensing signal on the at least one sensing resource and determine the sensing result based on the received sensing signal. If the receiving end and the RAN node are different devices, the receiving end can feed back the sensing result to the RAN node; if the receiving end is the RAN node, the RAN node determines the sensing result based on the received sensing signal.

[0214] It is understandable that, since the at least one sensing resource includes the first sensing resource, the sensing result can be considered to include the first sensing result, which is determined based on the sensing signal carried on the first sensing resource.

[0215] For example, based on Figure 10 In the example shown, the perception results can indicate that the target's speed is 0 within the coverage areas corresponding to beams #0 and #1, and greater than 0 within the coverage areas corresponding to beams #2 and #3. Therefore, the RAN node can determine from the perception results that the areas covered by beams #0 and #1 are mainly buildings or roadsides, with a low probability (or even 0) of high-speed targets; while the areas covered by beams #2 and #3 are mainly roads, with a higher probability of high-speed targets.

[0216] As one possible implementation, the RAN node can, based on prior information, identify the sensing resources corresponding to beams with a higher probability of high-speed targets appearing within the coverage area as the first sensing resources, for example... Figure 10 The sensing resource corresponding to beam #2 or beam #3 shown can be the first sensing resource. After determining the first sensing resource, second configuration information is sent to update the time unit interval of the first sensing resource to the second interval, thereby changing the speed measurement range, realizing flexible configuration of the speed measurement range and solving the problem of speed measurement ambiguity.

[0217] For sensing resources corresponding to beams with a low probability of high-speed targets appearing within the coverage area, such as Figure 10For the sensing resources corresponding to beams #0 and #1 shown, the RAN node may not update their time unit intervals, thus maintaining a low density of time units. Compared to updating the time unit intervals of all sensing resources to smaller intervals, this saves time-frequency resources occupied by sensing resources and reduces the impact of sensing on communication.

[0218] Scenario 3: The RAN node sends second configuration information based on the analysis of the sensing results. This is similar to Scenario 1 above, where the sensing network element analyzes the sensing results and sends third instruction information based on the analysis results. The difference is that in Scenario 3, the RAN sends second configuration information based on the analysis results, which will not be elaborated upon here.

[0219] Method 2: The RAN node sends third configuration information to the terminal. Correspondingly, the terminal receives the third configuration information from the RAN node. This third configuration information is used to configure at least one sensing resource, which includes the third sensing resource. The time unit interval of the third sensing resource includes a first interval and a second interval.

[0220] Within the first time period, the time unit interval of the third sensing resource is the first interval; in this case, the third sensing resource can be understood as the first sensing resource. Within the second time period, the time unit interval of the third sensing resource is the second interval; in this case, the third sensing resource can be understood as the second sensing resource. The first and second time periods do not overlap.

[0221] For example, the first time period can be the coherent processing time for indexes with odd numbers, and the second time period can be the coherent processing time for indexes with even numbers. Alternatively, the first time period can be the coherent processing time for indexes 1, 2, 4, 5, 7, 8..., and the second time period can be the coherent processing time for indexes 3, 6, 9..., without restriction.

[0222] In this scenario, the resource identifiers of the first and second sensing resources can be considered to be the same. That is, when initially configuring sensing resources, RAN nodes can configure two time unit intervals for certain sensing resources, enabling / activating different time unit intervals in different time periods, thereby achieving flexible changes in the speed measurement range.

[0223] For example, the third configuration information may include fourth and fifth indication information, whereby the fourth indication information indicates the first interval and the fifth indication information indicates the second interval. The fourth and fifth indication information can be carried by multiple bits, each value of which corresponds to a time unit interval. For example, the correspondence between bit values ​​and time unit intervals can be shown in Table 2.

[0224] Table 2

[0225] Bit value Time unit interval 00 2 OFDM symbols 01 4 OFDM symbols 10 8 OFDM symbols 11 16 OFDM symbols

[0226] Of course, there may be other correspondences between bit values ​​and time unit intervals. Table 2 is only an example description, and this application does not make specific limitations on such correspondences.

[0227] As one possible implementation, the third configuration information can also indicate the first time period and the second time period. Alternatively, the first time period and the second time period can be predefined by the protocol, preconfigured by the RAN node, or pre-negotiated by the RAN node and the terminal, without restriction.

[0228] As one possible implementation, the third sensing resource and the first reference resource have a QCL relationship. The determination of the third sensing resource can refer to Method 1 above to determine the relevant implementation of the first sensing resource, which will not be repeated here.

[0229] In one possible implementation, the third configuration information is used to configure at least one sensing resource, which has multiple available candidate time unit intervals, and the sensing resource corresponds to different time unit intervals in different time periods.

[0230] For example, when multiple sensing resources are configured in the third configuration information, each sensing resource can be configured with multiple available candidate time unit intervals. For instance, the third configuration information configures sensing resource 1, sensing resource 2, and sensing resource 3, and also configures time unit interval 11 and time unit interval 12 for sensing resource 1, time unit interval 21 and time unit interval 22 for sensing resource 2, and time unit interval 31 and time unit interval 32 for sensing resource 3.

[0231] Alternatively, when multiple sensing resources are configured in the third configuration information, these multiple sensing resources can be configured with multiple shared, available candidate time unit intervals. For example, if the third configuration information configures sensing resources 1, 2, and 3, and also configures time unit intervals a and b, then the time unit interval of sensing resource 1 is time unit interval a for a period of time and time unit interval b for another period of time; the time unit interval of sensing resource 2 is time unit interval a for a period of time and time unit interval b for another period of time; and the time unit interval of sensing resource 3 is time unit interval a for a period of time and time unit interval b for another period of time.

[0232] Optionally, when configured using either method one or method two, both the first sensing resource and the second sensing resource can have a QCL relationship with the first reference resource.

[0233] Based on the above method one or method two, for the same beam direction, multiple first sensing resources and second sensing resources can be configured in the time domain, and the first sensing resources and second sensing resources can be distributed at intervals, such as alternating distribution or multiple first sensing resources configured between two adjacent second sensing resources, so that the receiver can perform joint detection, thereby improving sensing performance.

[0234] For example, based on Figure 10 The example shown illustrates an alternating distribution of the first and second sensing resources in the time domain, with a carrier frequency of 260 GHz and a subcarrier spacing of 120 kHz. For beam #2, during the first coherent processing time, the RAN node can initially configure the time unit interval of the first sensing resource to two time slots, at which point the sensing speed range is approximately -11 to 11 m / s. Subsequently, during the second coherent processing time, the RAN node adjusts the time unit interval of the first sensing resource associated with beam #2 to seven OFDM symbols, at which point the sensing speed range is approximately -44 to 44 m / s.

[0235] In this scenario, if the actual speed of a target is 13 m / s, then in the first coherent processing time, due to velocity ambiguity, the target's speed will be falsely detected as 2 m / s. However, in the second coherent processing time, because the perceived speed range is larger, the target's speed can be accurately detected as 13 m / s. In other words, by jointly detecting within two coherent processing times, velocity ambiguity can be identified, and the true speed of the target with velocity ambiguity can be accurately perceived, thereby improving perception performance.

[0236] Method 3: The RAN node sends the fourth configuration information to the terminal. Correspondingly, the terminal receives the fourth configuration information from the RAN node.

[0237] The fourth configuration information is used to configure multiple sensing resources, including a first sensing resource and a second sensing resource. The time unit interval of the first sensing resource is a first interval, and the time unit interval of the second sensing resource is a second interval. For example, the first sensing resource and the second sensing resource may correspond to different beams, or the first sensing resource and the first reference resource may have a QCL relationship, and the second sensing resource and the second reference resource may have a QCL relationship, but the first reference resource and the second reference resource are different. The resource identifier of the first sensing resource and the resource identifier of the second sensing resource are different.

[0238] For example, based on Figure 10 In the example shown, the first sensing resource can be the sensing resource corresponding to beam #0 or beam #1, and the second sensing resource can be the sensing resource corresponding to beam #2 or beam #3.

[0239] In other words, in this third approach, the first and second sensing resources can be understood as different resources. The second sensing resource can be understood as a sensing resource configured simultaneously with the first sensing resource. That is, during the initial configuration of sensing resources, sensing resources with different time unit intervals can be configured for different beams.

[0240] As one possible implementation, the probability of a high-speed target appearing within the coverage area of ​​the beam corresponding to the first sensing resource is low, or even zero. For example, the beam corresponding to the first sensing resource covers buildings or roadsides. The probability of a high-speed target appearing within the coverage area of ​​the beam corresponding to the second sensing resource is high. For example, the beam corresponding to the second sensing resource covers roads. The acquisition of the coverage areas of the beams corresponding to the first and second sensing resources can be referred to the relevant description of scenario 2 in method one above, and will not be repeated here.

[0241] Based on this approach, compared to configuring sensing resources with smaller time unit intervals for all beams of the RAN node, the time and frequency resources occupied by sensing resources can be saved, allowing more time and frequency resources to be used for communication, thereby reducing the impact of sensing on communication.

[0242] It should be noted that the above three methods can be applied, or can be appropriately modified, to scenarios where the receiver of the sensing signal is another RAN node. For example, the first configuration information, the second configuration information, and the third configuration information are exchanged through the interface between RAN nodes, as described above, and will not be repeated here.

[0243] Figure 7 The illustrated embodiment distinguishes sensing resources with different time unit intervals from the perspective of two sensing resources (a first sensing resource and a second sensing resource). In one possible configuration, Figure 7 The first and second perceptual resources in the text are different names for the same perceptual resource at different time intervals. For ease of description, except... Figure 7 In addition to the method shown, this application also provides a sensing method, such as Figure 11 As shown, the sensing method includes the following steps:

[0244] S1101, the RAN node transmits a sensing signal on the first sensing resource. The time unit interval of the first sensing resource is the first interval.

[0245] As one possible implementation, the sensing resource is used to carry the sensing signal. The sensing resource includes at least one time unit. The time unit interval of the sensing resource is the interval between adjacent time units within the sensing resource. Refer to the relevant description in step S701 above; it will not be repeated here.

[0246] As one possible implementation, the first sensing resource and the first reference resource have a QCL relationship, for example, a QCLtypeD relationship. Refer to the above description of the first reference resource and this QCL relationship; further details will not be repeated here.

[0247] S1102, the RAN node updates the time unit interval of the first sensing resource from the first interval to the second interval, where the second interval is smaller than the first interval.

[0248] In other words, before step S1102, the time unit interval of the first sensing resource is the first interval. After step S1102, the time unit interval of the first sensing resource is updated to the second interval.

[0249] As one possible implementation, the parameters of the first sensing resource remain unchanged except for the time unit interval. Alternatively, the RAN node may also update other parameters of the first sensing resource, which is not specifically limited in this application.

[0250] S1103. The RAN node transmits a sensing signal on the updated first sensing resource. That is, the RAN node is the transmitter of the sensing signal.

[0251] As one possible implementation, in this embodiment, the updated first sensing resource can be understood as, or referred to as, the second sensing resource. Therefore, Figure 11 The detailed description of the updated first sensing resource can be found in the description of the second sensing resource in the above method embodiments, and will not be repeated here. The description of the first sensing resource before the update time unit interval can also be found in the description of the first sensing resource in the above method embodiments, and will not be repeated here.

[0252] Optionally, the RAN node can also send a sensing signal on the first sensing resource before the update. For example, after step S1101, the RAN node sends a sensing signal on the first sensing resource, then executes step S1102 to update the time unit interval of the first sensing resource from the first interval to the second interval, and then executes step S1103 to send a sensing signal on the updated first sensing resource.

[0253] As one possible implementation, the receiving end of the sensing signal can be the RAN node, that is, the RAN node performs self-transmission and self-reception; or, the receiving end of the sensing signal can be a terminal or another RAN node. This application does not specifically limit this, that is, step S1103 may also include: the RAN node / terminal / other RAN node receives the sensing signal on the updated first sensing resource. Figure 11 The following explanation uses the receiving end of the sensing signal as an example.

[0254] As is understandable, the receiving end of the sensing signal receives the signal formed after the sensing signal sent by the RAN node is reflected by targets in the surrounding environment. For ease of description, this embodiment uses the receiving end receiving the sensing signal as an example.

[0255] As one possible implementation, the first sensing resource with a time unit interval of the first interval and the first sensing resource with a time unit interval of the second interval can be distributed alternately. For example, the coherent processing time with an odd index includes the first sensing resource with a time unit interval of the first interval, and the coherent processing time with an even index includes the first sensing resource with a time unit interval of the second interval. Refer to the relevant description of the alternating distribution of the first and second sensing resources in step S703 above, which will not be repeated here.

[0256] As another possible implementation, after configuring multiple first sensing resources with a first time unit interval, a first sensing resource with a second time unit interval is configured. For example, a first sensing resource with a first time unit interval can be configured during the first and second coherent processing times, during the third coherent processing time, during the fourth and fifth coherent processing times, during the sixth coherent processing time, and so on. Refer to the description in step S703 above regarding the existence of multiple first sensing resources between two adjacent second sensing resources; it will not be repeated here.

[0257] As one possible implementation, when the receiver of the sensing signal is a terminal or another RAN node, the RAN node needs to send configuration information to the receiver to configure the sensing resources. For example, taking a terminal as the receiver of the sensing signal, the RAN node can configure the sensing resources in the following way:

[0258] The RAN node sends first configuration information and second configuration information to the terminal. Correspondingly, the terminal receives the first configuration information and second configuration information from the RAN node.

[0259] The first configuration information is used to configure the first sensing resource, and the time unit interval of the first sensing resource configured by the first configuration information is the first interval.

[0260] Optionally, the first configuration information may configure at least one sensing resource, which includes a first sensing resource with a time unit interval of a first interval, and the positions of the time units included in each sensing resource are different. Each of the at least one sensing resource configured in the first configuration information has a QCL relationship with a reference resource.

[0261] As one possible implementation, after the RAN node sends the first configuration information, it can send sensing signals on at least one sensing resource configured in the first configuration information. Correspondingly, after receiving the first configuration information, the terminal can determine at least one sensing resource, including the first sensing resource, based on the first configuration information. Furthermore, the terminal can receive sensing signals on this at least one sensing resource. Refer to the relevant description in Method 1 above; it will not be repeated here.

[0262] As one possible implementation, the RAN node can send the second configuration information to the terminal after sending the first configuration information.

[0263] The second configuration information is used to update the time unit interval of the first sensing resource from the first interval to the second interval. Alternatively, the second configuration information is used to update the time unit interval of some or all sensing resources that have a QCL relationship with the first reference resource to the second interval, wherein the some or all sensing resources that have a QCL relationship with the first reference resource include the first sensing resource.

[0264] Accordingly, after receiving the second configuration information, the terminal can determine the updated first sensing resource based on the second configuration information, and then receive sensing signals on the updated first sensing resource.

[0265] As one possible implementation, the second configuration information may include first indication information and second indication information. The first indication information indicates the first sensing resource, and the second indication information indicates the second interval. Refer to the relevant description in Method 1 above; it will not be repeated here.

[0266] In one possible implementation, the RAN node can send the second configuration information under scenario 1, scenario 2, or scenario 3. Scenario 1, scenario 2, and scenario 3 can be referred to the relevant descriptions in Method 1 above, and will not be repeated here.

[0267] It should be noted that the above configuration method for sensing resources can be applied to, or can be appropriately modified to, scenarios where the receiver of the sensing signal is another RAN node. For example, the first configuration information and the second configuration information can be exchanged through the interface between RAN nodes, as described above, and will not be repeated here.

[0268] Based on this scheme, the interval between adjacent time units in the sensing resources used to carry the sensing signal can be initially set to a larger interval. Subsequently, the interval between adjacent time units of the sensing resources can be adjusted to a smaller interval. Compared with before adjusting the time unit interval, the sensing speed range can be expanded, thereby achieving flexible adjustment of the sensing speed range. Furthermore, by using different sensing speed ranges, speed measurement ambiguity can be identified, and the actual speed of the target can be accurately sensed, solving the problem of speed measurement ambiguity and improving sensing performance. In addition, compared with always configuring a small time unit interval for the sensing resources, i.e., always configuring a high density of sensing resources, the scheme of this application can save the overhead of sensing resources and reduce the impact of sensing on communication.

[0269] Figure 11 In the method shown, the RAN node first configures a first sensing resource, and then updates the time unit interval of the first sensing resource from a first interval to a second interval. Furthermore, this application also provides a sensing method in which the RAN node can configure two time unit intervals for the same resource when configuring sensing resources. Figure 12 As shown, the sensing method includes the following steps:

[0270] S1201, the RAN node transmits sensing signals on the first sensing resource. That is, the RAN node is the transmitter of the sensing signals.

[0271] The time unit interval of the first sensing resource includes a first interval and a second interval, with the second interval being shorter than the first interval. The sensing resources and their time unit intervals can be found in the foregoing descriptions and will not be repeated here.

[0272] Within the first time period, the time unit interval of the first sensing resource is the first interval; within the second time period, the time unit interval of the first sensing resource is the second interval. The first and second time periods do not overlap.

[0273] As one possible implementation, the receiving end of the sensing signal can be the RAN node, that is, the RAN node performs self-transmission and self-reception; or, the receiving end of the sensing signal can be a terminal or another RAN node. This application does not specifically limit this, that is, step S1201 may also include: the RAN node / terminal / other RAN node receiving the sensing signal on the first sensing resource. Figure 12 The following explanation uses the receiving end of the sensing signal as an example.

[0274] As is understandable, the receiving end of the sensing signal receives the signal formed after the sensing signal sent by the RAN node is reflected by targets in the surrounding environment. For ease of description, this embodiment uses the receiving end receiving the sensing signal as an example.

[0275] As one possible implementation, the first sensing resource and the first reference resource have a QCL relationship, for example, a QCLtypeD relationship. Refer to the above description of the first reference resource and this QCL relationship; further details will not be repeated here.

[0276] As one possible implementation, the first time period and the second time period are periodic time periods, which alternate. For example, the first time period can be the coherent processing time with an odd index, and the second time period can be the coherent processing time with an even index.

[0277] As another possible implementation, there can be multiple first time periods between two adjacent second time periods. For example, the first time period can be a coherent processing time with indices of 1, 2, 4, 5, 7, 8... and the second time period can be a coherent processing time with indices of 3, 6, 9... without limitation.

[0278] As one possible implementation, the first sensing resource and the first reference resource have a QCL relationship. The determination of the first sensing resource can refer to Method 1 above to determine the relevant implementation of the first sensing resource, which will not be repeated here.

[0279] As one possible implementation, when the receiver of the sensing signal is a terminal or another RAN node, the RAN node needs to send configuration information to the receiver to configure the sensing resources. For example, taking a terminal as the receiver of the sensing signal... Figure 12 As shown, before step S1201, the method further includes:

[0280] The S1200 and RAN nodes send the first configuration information to the terminal. Correspondingly, the terminal receives the first configuration information from the RAN node.

[0281] The first configuration information is used to configure the first sensing resource. For example, the first configuration information may include a fourth indication information and a fifth indication information, whereby the fourth indication information indicates a first interval and the fifth indication information indicates a second interval. The relevant explanation of the third configuration information in Method Two above can be referred to, and will not be repeated here.

[0282] As one possible implementation, the first configuration information is also used to configure a first time period and / or a second time period. Refer to the explanation regarding the third configuration information indicating the first and second time periods in Method Two above; it will not be repeated here.

[0283] Based on this scheme, sensing resources can be configured with larger time unit intervals in one period and smaller time unit intervals in another period. This allows for flexible adjustment of the sensing speed range through different time unit intervals, enabling the identification of speed measurement ambiguity and accurate perception of the target's actual speed, thus resolving the speed measurement ambiguity problem and improving sensing performance. Furthermore, compared to consistently configuring sensing resources with smaller time unit intervals (i.e., consistently configuring high-density sensing resources), the scheme in this application can save on sensing resource overhead and reduce the impact of sensing on communication.

[0284] In one possible implementation, for the above method embodiments, in a CU-DU architecture or ORAN system, the function of interaction between the RAN node and the terminal can be implemented by the DU or O-DU. The information sent by the RAN node to the terminal can be generated by the DU or O-DU, or it can be generated by the CU or O-CU and sent to the DU or O-DU. The function of interaction between the RAN node and the core network can be implemented by the CU or O-CU. The processing function of the RAN node can be implemented by the CU or O-CU, or by the DU or O-DU, or by a combination of CU and DU (or O-CU and O-DU), without limitation.

[0310] All relevant content of each step involved in the above method embodiments can be referenced from the functional description of the corresponding functional module, and will not be repeated here.

[0311] In this application, the communication device 130 can be presented in an integrated manner, divided into various functional modules. Here, "module" can refer to an application-specific integrated circuit (ASIC), a circuit, a processor and memory that executes one or more software or firmware programs, integrated logic circuits, and / or other devices that can provide the above functions.

[0312] In some embodiments, when Figure 13 When the communication device 130 is a chip or chip system, the function / implementation process of the transceiver module 1302 can be implemented through the input / output interface (or communication interface) of the chip or chip system, and the function / implementation process of the processing module 1301 can be implemented through the processor (or processing circuit) of the chip or chip system.

[0313] Since the communication device 130 provided in this embodiment can execute the above method, the technical effects it can achieve can be referred to the above method embodiment, and will not be repeated here.

[0314] As a possible product form, the RAN node or terminal described in the embodiments of this application can be implemented using one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gate logic, discrete hardware components, any other suitable circuits, or any combination of circuits capable of performing the various functions described throughout this application.

[0315] As another possible product form, the RAN node or terminal described in the embodiments of this application can be implemented using a general bus architecture. For ease of explanation, see [link to documentation]. Figure 14 , Figure 14 This is a schematic diagram of the structure of a communication device 1400 provided in an embodiment of this application. The communication device 1400 includes a processor 1401 and a transceiver 1402. The communication device 1400 can be a RAN node, or a chip or chip system therein; or, the communication device 1400 can be a terminal, or a chip or module therein. Figure 14 Only the main components of the communication device 1400 are shown. In addition to the processor 1401 and transceiver 1402, the communication device may further include a memory 1403 and input / output devices. Figure 14 (Not indicated).

[0317] Optionally, the processor 1401, transceiver 1402, and memory 1403 can be connected via a communication bus.

[0318] When the communication device is powered on, the processor 1401 can read the software program in the memory 1403, execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 1401 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit. The RF circuit processes the baseband signal and transmits the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1401. The processor 1401 converts the baseband signal into data and processes the data.

For example, in a distributed scenario, the radio frequency circuitry and antenna can be arranged remotely, independent of the communication device.
