Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0049] FIG. 1 is a schematic diagram of an application scenario according to an embodiment of the present application.

[0050] As shown in FIG. 1, a communication system 100 can include a first device 110 and a second device 120. The second device 120 can communicate with the first device 110 through an air interface. The first device 110 and the second device 120 support multi-service transmission.

[0051] It should be understood that the embodiments of the present application are only exemplarily described with reference to the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Long Term Evolution (LTE) system, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), an Internet of Things (IoT) system, a Narrow Band Internet of Things (NB-IoT) system, an enhanced Machine-Type Communications (eMTC) system, a 5G communication system (also referred to as a New Radio (NR) communication system), a 6th generation mobile communication (6G) system, or a future communication system, etc.

[0052] In the communication system 100 shown in FIG. 1, the second device 120 can be an access network device that communicates with the first device 110. The access network device can provide communication coverage for a particular geographic area, and can communicate with the first device 110 (e.g., a user equipment (UE)) located within the coverage area.

[0054] The first device 110 can be any first device, including but not limited to a first device that employs wired or wireless connection with the second device 120 or other first devices.

[0055] For example, the first device 110 can refer to an Ambient-Internet of Things (A-IOT) device, an access terminal, a UE, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user equipment.

[0056] The first device 110 can be used for Device to Device (D2D) communication.

[0057] The wireless communication system 100 can further include a core network device 130 in communication with the second device 120, which can be a 5G core (5GC) device, e.g., an Access and Mobility Management Function (AMF), e.g., an Authentication Server Function (AUSF), e.g., a User Plane Function (UPF), e.g., a Session Management Function (SMF). Alternatively, the core network device 130 can also be an Evolved Packet Core (EPC) device of an LTE network, e.g., a Session Management Function + Core Packet Gateway (SMF + PGW-C) device. It should be understood that the SMF + PGW-C can implement the functionalities of both the SMF and the PGW-C. During the evolution of the network, the core network device can also be referred to as other names, or new network entities can be formed by dividing the functions of the core network, which are not limited by the embodiments of the present application.

[0058] The functional units in the communication system 100 can also be connected and communicate through a next generation (NG) interface.

Optionally, the wireless communication system 100 can comprise a plurality of second devices 120 and each second device 120 can comprise other number of first devices 110 within its coverage. The embodiments of the present application do not limit the number of second devices 120 and the number of first devices 110 within the coverage of each second device 120.

[0061] It should be noted that Fig. 1 is only used to illustrate the system to which the embodiments of the present application are applied. Of course, the method shown in the embodiments of the present application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in the present application. The term "and / or" in the present application is only used to describe the association relationship of the associated objects. It means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the associated objects. It should also be understood that the "indication" mentioned in the embodiments of the present application can be direct indication or indirect indication, or can represent an associated relationship.

The present application does not limit this.

[0062] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all of them belong to the protection scope of the embodiments of the present application.

[0063] The next generation network (e.g., 6G communication network) is expected to be a fusion of mobile communication network, sensing network and computing network. In a narrow sense, the sensing network refers to a system with the ability of target positioning (range finding, speed measurement, angle measurement), target imaging, target detection, target tracking and target identification, and in a broad sense, refers to a system with all services, networks, users and terminals, and the attributes and states of environmental objects. From the perspective of sensing applications, sensing can include the following categories:

[0064] (1) Outdoor / wide area / local area applications: including smart city (e.g., weather monitoring, etc.), smart transportation / high-speed rail (e.g., high-precision map construction, road supervision, intrusion detection, etc.), low-altitude application (e.g., unmanned aerial vehicle monitoring and obstacle avoidance, flight intrusion detection, flight path management, etc.), etc.

[0065] (2) Indoor / local area applications: including smart home and health management (e.g., respiratory monitoring, intrusion detection, gesture / posture recognition, motion monitoring, mobile trajectory tracking, etc.), smart factory (e.g., intrusion detection, material detection, defect detection of goods, etc.), etc.

[0066] The above is only an exemplary classification of some sensing applications, and the application areas of sensing are not limited to the above examples.

[0067] Wireless communication and sensing are two important applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment to achieve target positioning, action recognition, imaging and other environmental sensing. Traditional sensing and wireless communication exist independently, and the separate design wastes wireless spectrum and hardware resources.

[0068] In the era of Beyound 5G (B5G) and 6G, communication spectrum moves to millimeter wave, terahertz, and visible light communication. In the future, the spectrum of wireless communication will coincide with the traditional sensing spectrum. The communication and sensing integration technology integrates wireless communication and sensing functions, which can use wireless resources of wireless communication to realize the function of sensing; can use the widely deployed cellular network to realize sensing services in a larger area; can use base stations and multiple terminals for joint sensing to achieve higher sensing accuracy; and can reuse the hardware modules of wireless communication to realize sensing functions and reduce costs.

[0069] In summary, the communication and sensing integration technology enables the future wireless communication system to have sensing capability, providing a basis for the development of future smart transportation, smart city, smart factory, unmanned aerial vehicle and other services.

[0070] According to the different sensing signal sending and receiving modes, sensing can be divided into at least 8 working modes:

[0071] (1) Base station self-generation and self-reception sensing mode

[0072] Referring to FIG. 2, the base station self-transmit self-receive sensing mode is that the base station Remote Radio Unit (RRU) or the base station uses the reflection / diffraction signals of the communication signals transmitted by itself for sensing, which is a typical case considered in the system in which the sensing receiver and the transmitter are jointly deployed at the same location, such as a single station radar. The base station self-transmit self-receive sensing enables the base station to sense the information of the surrounding environment. Since the transmitter and the receiver are on the same platform, they can be easily synchronized at the clock level, and the sensing result can be clearly resolved by the single base station node without the assistance of external equipment. However, this setup requires the base station to have full duplex capability or equivalent capability.

[0073] (2) Terminal self-transmit self-receive sensing mode

[0074] Referring to FIG. 3, the terminal self-transmit self-receive sensing mode is similar to the base station self-transmit self-receive sensing mode, that is, the terminal uses the reflection / diffraction signals of the communication signals transmitted by itself for sensing.

[0075] (3) Inter-base station cooperative sensing mode

[0076] Referring to FIG. 4, the inter-base station cooperative sensing mode refers to a case in which a base station uses the downlink communication signals received from other base stations for sensing. In terms of sensing, this is equivalent to the setup of a double station and a multi-station radar, in which the transmitter and the receiver are spatially separated, but their clock requirements are synchronized. The inter-base station cooperative sensing mode can adapt to the positions of the sensing target and the environment in real time, and is particularly suitable for high-speed mobile scenarios such as highways and high-speed rails, and can provide near-global coverage sensing services.

[0077] (4) Inter-terminal cooperative sensing mode

[0078] Referring to FIG. 5, the inter-terminal cooperative sensing mode is similar to the inter-base station cooperative sensing mode, that is, a terminal uses the downlink communication signals received from other terminals for sensing. The inter-terminal cooperative sensing mode is mainly used in indoor local scenarios. Considering the complex propagation environment in indoor scenarios, the direct path for base station sensing is less, and the sensing performance is severely affected. At the same time, with the development of intelligent devices, the number and types of intelligent terminal devices in indoor scenarios are increasing. The inter-terminal cooperative sensing mode will effectively improve the sensing performance and efficiency of indoor environments.

[0079] (5) Base station-terminal cooperative sensing mode

[0080] Referring to FIG. 6, the base station-terminal cooperative sensing mode refers to a case in which the base station transmits downlink communication signals, and the terminal performs sensing based on the received downlink communication signals.

[0081] (6) Terminal-base station cooperative sensing mode

[0082] Referring to FIG. 7, the terminal-base station cooperative sensing mode refers to that the terminal transmits an uplink communication signal, and the base station performs sensing based on the received uplink communication signal.

[0083] (7) Sensing mode in which the sensed target is a sensing signal transmitting node

[0084] Referring to FIG. 8, the sensing mode in which the sensed target is a sensing signal transmitting node refers to that the sensed target (e.g., a terminal or an electronic device, etc.) transmits an uplink communication signal to the base station, and the base station performs sensing based on the received uplink communication signal.

[0085] (8) Sensing mode in which the sensed target is a sensing signal receiving node

[0086] Referring to FIG. 9, the sensing mode in which the sensed target is a sensing signal receiving node refers to that the sensed target (e.g., a terminal or an electronic device, etc.) receives a downlink communication signal transmitted by the base station, and performs sensing based on the received uplink communication signal.

[0087] It should be noted that the sensing signal transmitting node and the sensing signal receiving node can be collectively referred to as a sensing node, and in the above eight working modes, there is only a single or a pair of sensing nodes, while in a wireless communication system, the number of terminal devices (mobile phones, IoT devices, etc.) is large. When there are multiple sensing nodes (i.e., base stations, mobile phones, IoT devices, etc. that can transmit and / or receive sensing signals) around a sensed object, multiple sensing nodes participating in sensing can improve the accuracy of sensing, and can meet more complex sensing service requirements and provide more abundant sensing services. When there are multiple sensing nodes in a wireless communication system, a sensing control node can be present to control and manage the entire sensing service to improve efficiency. The sensing control node can be a base station, a terminal, or a core network element. An example in which multiple sensing nodes participate in sensing is shown in FIG. 10. The communication system 100 can include a first sensing node 1001, a second sensing node 1002, a third sensing node 1003, a fourth sensing node 1004, and a fifth sensing node 1005.

[0088] In a wireless communication system, a sensing signal (reference signal) can be used as a channel state information reference signal (CSI-RS) to measure channel state, or as a demodulation reference signal (DMRS) to assist demodulation, or as a phase noise tracking reference signal (PT-RS) to assist positioning, etc. The signal is usually continuously mapped or equally spaced mapped in a certain bandwidth in the frequency domain. For example, the DMRS is continuously mapped in the frequency domain range occupied by a physical uplink shared channel (PUSCH) / physical downlink shared channel (PDSCH) or the like, and occupies all subcarriers. The CSI-RS can be mapped at an interval of subcarriers in the full system bandwidth, but this way cannot flexibly configure frequency domain resources for different sensing signals according to different sensing purposes, resulting in poor sensing effect.

[0089] Therefore, embodiments of the present application provide a resource configuration method. A first device can determine resource configuration information used when transmitting a first sensing signal. Based on this, frequency domain resources can be flexibly configured based on channel state when transmitting the first sensing signal. In this way, the sensing effect is improved, and resource overhead is saved.

[0090] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0091] FIG. 11 shows a resource configuration method provided by an embodiment of the present application. The method can include:

[0092] S100, a first device sends resource configuration information, which is used to determine a first frequency domain resource where a first sensing signal is located.

[0093] It should be noted that the resource configuration information can be sent by the first device in a broadcast or multicast manner. The resource configuration information can be used not only to send the first sensing signal, but also to receive the first sensing signal.

[0094] It should be noted that the resource configuration method provided in the embodiments of the present application can be applied to various communication scenarios, such as a cellular communication scenario and a WiFi communication scenario, and the embodiments of the present application do not limit this.

[0095] It can be seen that, in the resource configuration method provided in the embodiments of the present application, the first device can determine the first frequency domain resource in which the first sensing signal is located, and based on this, the frequency domain resource can be flexibly configured based on the channel state when the first sensing signal is transmitted. In this way, not only the sensing effect is improved, but also the resource overhead is saved.

[0096] In some embodiments, the first device mentioned in the embodiments of the present application can be a base station, a terminal, a server, a core network, or a sensing information collector, and the embodiments of the present application do not limit this.

[0097] In an optional embodiment of the present application, the first device is a sensing configuration node, that is, the first device only configures resource configuration information and sends the configured resource configuration information to a second device (a sensing signal receiving node) and a third device (a sensing signal sending node), the third device determines the first frequency domain resource based on the received resource configuration information, and then sends the first sensing signal to the second device on the first frequency domain resource. Meanwhile, the second device determines the first frequency domain resource based on the received resource configuration information, and then receives the first sensing signal sent by the third device on the first frequency domain resource.

[0098] In the embodiments of the present application, the first device sends the first sensing signal.

[0099] In another optional embodiment of the present application, the first device is not only a sensing configuration node but also a sensing signal sending node, that is, the first device not only configures resource configuration information and sends it to the second device, but also sends the first sensing signal to the second device on the first frequency domain resource corresponding to the configured resource configuration information. Meanwhile, the second device determines the first frequency domain resource based on the received resource configuration information, and then receives the first sensing signal sent by the third device on the first frequency domain resource.

[0100] In the embodiments of the present application, the first frequency domain resource includes a first subcarrier in a first resource block group, and the resource configuration information includes one or more of the following:

[0101] The first configuration information is used to determine the first resource block group;

[0102] The second configuration information is used to determine the first subcarrier in at least one first resource block group in the first resource block group; the first subcarrier is used to transmit the first sensing signal;

[0103] The third configuration information is used to determine the number of resource blocks and / or the number of subcarriers in at least one first resource block group.

[0104] It should be noted that there are multiple resource block groups (RBGs) on the bandwidth of the sensing system, and when the first sensing signal is transmitted, the first sensing signal can be transmitted on the first resource block group in the multiple resource block groups based on the first configuration information in the resource configuration information, where the number of the first resource block group is 1 or more, and the present embodiment does not limit this.

[0105] It should be noted that since there are multiple resource blocks (RBs) on each resource block group RBG, each resource block RB usually includes 12 subcarriers, and therefore when the first sensing signal is transmitted, the first sensing signal can be transmitted on the first subcarrier of each first resource block group in the at least one first resource block group based on the second configuration information in the resource configuration information, where the number of the first subcarrier is 1 or more, and the present embodiment does not limit this.

[0106] It should be noted that the third configuration information can be used to determine the number of resource blocks RB in each resource block group RBG in the at least one first resource block group, and after the number of resource blocks RB in each resource block group RBG is determined, the number of subcarriers in each resource block group RBG can be determined.

[0107] It should be noted that the first resource block group, the first subcarrier, and the number of subcarriers can be determined based on the resource configuration information, or can be agreed through a protocol, and the present embodiment does not limit this.

[0108] In the present embodiment, the first device transmits the first sensing signal on the first subcarrier in the first resource block group, and the first resource block group and the first subcarrier are determined based on the resource configuration information.

[0109] It should be noted that the first frequency domain resource is the first subcarrier in the first resource block group, that is, the first device determines the first resource block group according to the first configuration information in the resource configuration information, and determines the first subcarrier according to the second configuration information and the third configuration information, and then the first device can transmit the first sensing signal to the second device on the first subcarrier in the first resource block group.

[0110] In the present embodiment, the first device receives the sensing information and / or the feedback information, and the sensing information and / or the feedback information are determined based on the first sensing signal.

[0111] It should be noted that after the second device receives the resource configuration information sent by the first device, first, the second device determines the first frequency domain resource for receiving the first sensing signal according to the resource configuration information, that is, the first subcarrier in the first resource block group, then the second device receives the first sensing signal sent by the first device / third device on the first subcarrier in the first resource block group, and performs sensing and / or measurement based on the first sensing signal to obtain sensing information and / or feedback information, and finally, the second device sends the sensing information and / or feedback information to the first device and / or the third device.

[0112] It should be noted that if the first sensing signal is sent by the first device to the second device, the third device does not participate in sensing, at this time, the second device only needs to send the sensing information and / or feedback information to the second device, if the first sensing signal is sent by the third device to the second device, at this time, the second device can choose to send the sensing information and / or feedback information to the first device and the third device, or can choose to send the sensing information and / or feedback information to only the first device or the third device, and the embodiments of the present application do not limit this.

[0113] In the embodiments of the present application, the first configuration information includes any one of the following:

[0114] The first sequence number is used to determine the first resource block group;

[0115] The first start sequence number is used to determine the starting resource block group of the first resource block group, and the first length is used to determine the number of resource block groups in the first resource block group;

[0116] The first mapping information is used to determine the first resource block group;

[0117] The first comb mapping interval is used to determine the first resource block group.

[0118] It should be noted that the first configuration information is used to determine the first resource block group for transmitting the first sensing signal, which can specify a resource block group RBG by the first sequence number, can indicate a plurality of continuous resource block groups RBG by the first start sequence number and the first length, can indicate any resource block group RBG in the frequency domain range by the first mapping information, or can configure the interval of the resource block group RBG occupied by the first sensing signal by the first comb interval, and the embodiments of the present application do not limit this.

[0119] In an example, the location of the first resource block group is agreed by protocol, for example, the protocol agrees to transmit the first sensing signal on the first resource block group RBG of the system bandwidth, or the protocol agrees to transmit the first sensing signal on the middle resource block group RBG of the system bandwidth, or the protocol agrees to transmit the first sensing signal on the last resource block group RBG of the system bandwidth, etc.

[0120] In an example, the location of the first resource block group is determined by a first sequence number in the first configuration information, since a corresponding sequence number is edited in advance for each resource block group RBG of the system bandwidth, the first resource block group can be indicated by the first sequence number; referring to FIG. 12, if the first sequence number is 6, the resource block group RBG with the sequence number of 6 is the first resource block group, which is used to transmit the first sensing signal.

[0121] In an example, the location of the first resource block group is determined by a first start sequence number and a first length in the first configuration information, since a corresponding sequence number is edited in advance for each resource block group RBG of the system bandwidth, the start resource block group RBG can be indicated by the first start sequence number, and then the number of resource block groups in the first resource block group is indicated by the first length; referring to FIG. 13, if the first start sequence number is 5 and the first length is 5, the first resource block group is composed of the continuous 5 resource block groups RBG starting from the resource block group RBG with the sequence number of 5, which is used to transmit the first sensing signal.

[0122] In an example, the location of the first resource block group is determined by a first mapping information bitmap in the first configuration information, at this time, the number of bits in the first mapping information bitmap is the same as the number of resource block groups RBG in the system bandwidth, each bit in the first mapping information bitmap corresponds to a resource block group RBG, and the bit value of 1 indicates that the corresponding resource block group RBG is used to transmit the first sensing signal, and the bit value of 0 indicates that the corresponding resource block group RBG is not used to transmit the first sensing signal; referring to FIG. 14, it can be seen that if the bit values of the 1st bit, the 5th bit, the 7th bit and the 14th bit in the first mapping information bitmap are 1, and the bit values of the remaining bits are all 0, the first resource block group is composed of the 4 resource block groups RBG corresponding to the 1st bit, the 5th bit, the 7th bit and the 14th bit, which is used to transmit the first sensing signal.

[0123] In an example, the location of the first resource block group is determined by a first comb mapping interval in the first configuration information, at this time, the interval value of the first comb mapping interval is used to determine the first resource block group from the resource block groups RBG of the system bandwidth; referring to FIG. 15, it can be seen that if the interval value of the first comb mapping interval is 4, the first resource block group is composed of 1 resource block group RBG every 4 resource block groups RBG starting from the first resource block group RBG of the system bandwidth, which is used to transmit the first sensing signal.

[0124] It can be understood that the first configuration information can select continuous, or periodic, or random frequency domain positions for the transmission of the first sensing signal, which can adapt to different sensing accuracy requirements. Based on this, a frequency domain position with better channel conditions can be selected for sensing, which can not only improve the sensing effect, but also improve the resource utilization of the system.

[0125] In the embodiments of the present application, the second configuration information includes any one of the following:

[0126] Second mapping information, the number of bits in the second mapping information is the same as the number of subcarriers in the at least one first resource block group, and the value of each bit in the second mapping information is used to indicate a first subcarrier from the at least one first resource block group;

[0127] Second starting sequence number and second length, the second starting sequence number is used to indicate a starting subcarrier of the first subcarrier from the at least one first resource block group, and the second length is used to indicate the number of subcarriers in the first subcarrier;

[0128] Second comb mapping interval, the interval value of the second comb mapping interval is used to indicate the first subcarrier from the at least one first resource block group.

[0129] It should be noted that the second configuration information is used to determine the first frequency domain resource for transmitting the first sensing signal, i.e., the first subcarrier in the first resource block group. The second mapping information can be used to indicate any subcarrier on each first resource block group in the at least one first resource block group, the second starting sequence number and the second length can be used to indicate consecutive subcarriers from each first resource block group, and the second comb mapping interval can be used to configure the interval of the subcarriers occupied by the first sensing signal. The embodiments of the present application do not limit this.

[0130] In an example, the position of the first subcarrier is determined by the second mapping information bitmap in the second configuration information. At this time, the number of bits in the second mapping information bitmap is the same as the number of subcarriers in each first resource block group, each bit in the second mapping information bitmap corresponds to a subcarrier, and the bit value of 1 indicates that the corresponding subcarrier is used for transmitting the first sensing signal, and the bit value of 0 indicates that the corresponding subcarrier is not used for transmitting the first sensing signal. Referring to FIG. 16, it can be seen that for each first resource block group, if there are 48 subcarriers in a first resource block group, the bit values of the 2nd bit, the 5th bit, and the 46th bit in the second mapping information bitmap are 1, and the bit values of the remaining bits are all 0. Then, the 4 subcarriers corresponding to the 2nd bit, the 5th bit, and the 46th bit form the first subcarrier, which is used for transmitting the first sensing signal.

[0131] In an example, the position of the first subcarriers is determined by a second starting sequence number and a second length in the second configuration information. For each first resource block group, since the corresponding sequence number is edited in advance for each subcarrier therein, the starting subcarrier can be indicated by the second starting sequence number, and then the number of subcarriers in the first subcarriers is indicated by the second length. Referring to FIG. 17, if the second starting sequence number is 1 and the second length is 5, the first subcarriers are composed of the continuous 5 subcarriers starting from the subcarrier with the sequence number 1 in each first resource block group, and are used to transmit the first sensing signal.

[0132] In an example, the position of the first subcarriers is determined by a second comb mapping interval in the second configuration information. At this time, the interval value of the second comb mapping interval is used to determine the first subcarriers from each first resource block group. Referring to FIG. 18, it can be seen that if the interval value of the second comb mapping interval is 2, the first subcarriers are composed of every 2 subcarriers starting from the first subcarrier in each first resource block group, and are used to transmit the first sensing signal.

[0133] It can be understood that the second configuration information can be used to flexibly select the frequency domain interval for the transmission of the first sensing signal, which can adapt to different sensing range requirements, improve the sensing effect, and improve the resource utilization rate of the system and save the sensing resource overhead.

[0134] In the embodiments of the present application, the third configuration information includes a first value, the first value is used to indicate the number of resource blocks in at least one first resource block group, and the number of subcarriers is determined according to the number of resource blocks and the subcarriers in each resource block.

[0135] It should be noted that since the determined first resource block group used to transmit the first sensing signal includes at least one first resource block group, when the first subcarriers are determined from each first resource block group according to the second configuration information, the number of subcarriers in each first resource block group needs to be determined first. It can be known that each first resource block group includes one or more resource blocks RB, and each RB usually includes 12 subcarriers. Based on this, the number of subcarriers in each first resource block group can be determined.

[0136] It should be noted that the number of resource blocks RB included in each first resource block group can be determined by protocol agreement or by the third configuration information, and the embodiments of the present application do not limit this.

[0137] In an example, if the first value contained in the third configuration information is 4, it indicates that each first resource block group includes 4 resource blocks (RBs), and since each RB usually includes 12 subcarriers, it can be determined that the number of subcarriers in each first resource block group is 48. Correspondingly, if the first value contained in the third configuration information is 6, it indicates that each first resource block group includes 6 resource blocks (RBs), and since each RB usually includes 12 subcarriers, it can be determined that the number of subcarriers in each first resource block group is 72.

[0138] For example, referring to FIG. 19, an example manner of determining the first subcarriers of the first resource block groups is provided in the embodiments of the present application. First, based on the first mapping information in the first configuration information, it is determined that the first resource block groups are the resource block groups (RBGs) with serial numbers 4, 8 and 12 in the system bandwidth. Then, based on the third configuration information, it is determined that each resource block group (RBG) in the system bandwidth includes 4 resource blocks (RBs). Since each resource block (RB) usually includes 12 subcarriers, each first resource block group (RBG) in the first resource block groups includes 48 subcarriers. Finally, based on the interval value of the second comb mapping interval in the second configuration information, it is determined that the first subcarriers are formed by 2 subcarriers occupying 1 subcarrier starting from the first subcarrier in each first resource block group, and the first subcarriers are used to transmit the first sensing signal.

[0139] In an optional embodiment of the present application, the first device is a sensing configuration node, the second device is a sensing signal receiving node, and the third device is a sensing signal transmitting node. An example signaling flow is as follows:

[0140] The first device transmits the first configuration information, and / or the second configuration information, and / or the third configuration information.

[0143] In another alternative embodiment of the present application, the first device is a sensing configuration node and a sensing signal sending node, the second device is a sensing signal receiving node, and an exemplary signaling flow is as follows:

[0144] The first device sends the first configuration information, and / or the second configuration information, and / or the third configuration information, and sends the first sensing signal on the first subcarriers of the first resource block group corresponding to the first configuration information, and / or the second configuration information, and / or the third configuration information.

Based on this, the frequency domain positions with better channel conditions can be selected for sensing, which can not only improve the sensing effect, but also improve the resource utilization of the system by flexible configuration.
