[0001] The present application claims priority from the Chinese patent application No. 202411110673.2 and titled "A communication method and related apparatus" filed on August 13, 2024 with the State Intellectual Property Office, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular, to a communication method and related apparatus. BACKGROUND

[0003] Wireless communication can be transmission communication between two or more communication nodes without propagation through a conductor or cable. Generally, the communication nodes can include one or more network devices and / or one or more terminal devices.

[0004] Currently, in a communication system, a communication device can calculate and determine a transmission resource of a signal, and perform transmission and reception of the signal on the transmission resource. For example, the transmission resource can include a time domain resource, a frequency domain resource, etc. for carrying the signal. In this way, different communication devices can transmit service data related to a communication service through the communication system to obtain a communication service.

[0005] With the development of communication technology, in addition to providing communication services, future communication systems can also provide perception services. However, for communication devices, how to implement object perception is a technical problem to be solved. SUMMARY

[0006] The present application provides a communication method and related apparatus for improving perception performance.

[0007] The first aspect of the present application provides a communication method, which is performed by a first communication device. The first communication device can be a communication apparatus (e.g., a terminal device or a network device), or the first communication device can be a part of the communication apparatus (e.g., a circuit or a chip responsible for communication functions (e.g., a Modem chip (also referred to as a baseband chip), a system on chip (SoC) chip, such as an SoC chip including a modem core, or a system in package (SIP) chip), etc.), or the first communication device can also be a logic module or software capable of implementing all or part of the functions of the communication apparatus. In the method, the first communication device determines a first signal, the first signal is carried in a first frequency band, and the first signal is used for sensing. The first frequency band is different from a second frequency band. The second frequency band is located in a mobile service spectrum, and part or all of the first frequency band is located in a radio location service (RLS) spectrum. The first communication device transmits the first signal.

[0008] Based on the above scheme, the first communication device transmits a first signal used for sensing, and the first signal is carried in a first frequency band, which is different from a second frequency band. The second frequency band is located in a mobile service spectrum, and part or all of the first frequency band is located in a radio location service spectrum. In other words, part or all of the sensing signal can be carried in the radio location service spectrum. Thus, different communication devices can use the radio location service spectrum to implement the transmission of the sensing signal, and can avoid or reduce the interference of the communication signal transmitted in the mobile service spectrum on the sensing signal, so as to improve the sensing performance.

[0009] Optionally, the bandwidth of the first frequency band can be greater than the bandwidth of the second frequency band. Since the size of the sensing bandwidth is positively correlated with the level of the sensing performance (for example, increasing the sensing bandwidth can improve the sensing resolution and can achieve finer-grained distance sensing; for another example, increasing the sensing bandwidth can obtain more sensing data acquisition, and can obtain more sensing information), therefore, different communication devices can use the first frequency band to implement the transmission of the sensing signal, so as to further improve the sensing performance.

[0010] It should be understood that the mobile service spectrum can refer to a spectrum used for wireless communication, including but not limited to an international mobile telecommunications (IMT) spectrum, or a wireless access system / radio local area network (WAS / RLAN) spectrum, etc.

[0011] It should be appreciated that the radio location service spectrum can be replaced by other implementations different from the mobile service spectrum, such as the amateur service spectrum, or the fixed service (FS) spectrum, etc.

[0012] In this application, a frequency band can be replaced by other terms, such as a frequency spectrum, a frequency band, a frequency domain, a frequency domain resource, a frequency spectrum resource, a frequency, a frequency interval, a frequency resource, or a channel, etc. For example, the first frequency band can be replaced by the first frequency spectrum, the first frequency band, the first frequency domain, the first frequency domain resource, the first frequency spectrum resource, the first frequency, the first frequency interval, the first frequency resource, or the first channel, etc. For another example, the second frequency band can be replaced by the second frequency spectrum, the second frequency band, the second frequency domain, the second frequency domain resource, the second frequency spectrum resource, the second frequency, the second frequency interval, the second frequency resource, or the second channel, etc.

[0013] Similarly, in this application, a frequency spectrum can be replaced by other terms, such as a frequency band, a frequency domain, a frequency domain resource, a frequency spectrum resource, a frequency, or a frequency resource, etc. For example, the mobile service spectrum can be replaced by the mobile service frequency band, the mobile service frequency band, the mobile service frequency domain, the mobile service frequency domain resource, the mobile service frequency spectrum resource, the mobile service frequency, or the mobile service frequency resource, etc. For another example, the radio location service spectrum can be replaced by the radio location service frequency band, the radio location service frequency band, the radio location service frequency domain, the radio location service frequency domain resource, the radio location service frequency spectrum resource, the radio location service frequency, or the radio location service frequency resource, etc.

In the technical solutions provided in the embodiments of the present application, the device for implementing the function of the network device is taken as an example to describe the technical solutions provided in the embodiments of the present application.

[0105] (3) Configuration and pre-configuration: in the present application, configuration and pre-configuration will be used simultaneously. Configuration refers to that the network device sends some parameter configuration information or parameter values to the terminal device through a message or signaling, so that the terminal device determines the communication parameters or the resources in the transmission according to the values or information. Pre-configuration is similar to configuration, which can be parameter information or parameter values agreed by the network device and the terminal device in advance, or parameter information or parameter values adopted by the network device or the terminal device according to a standard protocol, or parameter information or parameter values pre-stored in the network device or the terminal device. The present application does not limit this.

[0106] Further, the values and parameters can be changed or updated.

[0107] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" refers to one or more, and "multiple" refers to two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the cases of A alone, A and B together, and B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or multiple items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0108] (5) In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.

[0109] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0110] It can be understood that the information may be processed as necessary between the source and the destination of the information transmission, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood, and will not be repeated here.

[0111] (6) In embodiments of the present application, "indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. Information indicated by certain information (indication information described below) is referred to as to-be-indicated information. In a specific implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and other parts of the to-be-indicated information are known or agreed in advance. For example, the indication of specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, predefined by a protocol), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that the indication information can be used to indicate the to-be-indicated information for a sender of the indication information, and the indication information can be used to determine the to-be-indicated information for a receiver of the indication information.

[0112] In the present application, the same or similar parts between various embodiments can be mutually referred to, unless otherwise specified. In various embodiments of the present application, and various implementation manners / implementation methods / implementation approaches in each embodiment, if there is no special specification and no logical conflict, the terms and / or descriptions between different embodiments, and between various implementation manners / implementation methods / implementation approaches in each embodiment are consistent and can be mutually referred to, and the technical features in different embodiments, and in various implementation manners / implementation methods / implementation approaches in each embodiment can be combined to form new embodiments, implementation manners, implementation methods, or implementation approaches according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.

[0113] In order to facilitate understanding of the method provided by the embodiments of the present application, the system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is used to more clearly illustrate the scheme of the embodiments of the present application, and does not constitute a limitation on the scheme provided by the embodiments of the present application.

[0114] Referring to FIG. 1a, an architecture diagram of a communication system 1000 to which embodiments of the present application are applied is shown. As shown in FIG. 1a, the communication system includes a RAN 100 and a core network 200, and optionally, the communication system 1000 can further include an Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1a, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1a, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1a). The terminal 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is connected to the core network 200 through wire or wireless. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network device and the logical functions of the RAN node. The terminals can be connected to each other and the RAN nodes can be connected to each other through wire or wireless.

[0115] FIG. 1b shows an example diagram of an O-RAN system, which can include other components than those shown in the figure. As shown, an access network device (RAN, which can be an eNB or a gNB or a next generation access network device) communicates with a core network (CN) through a backhaul link and communicates with a UE through an air interface.

[0116] In a possible implementation, the present application can be applied to a long term evolution (LTE) wireless communication system, an NR wireless communication system, and a future evolved new radio (NR) wireless communication system. For example, the present application can be applied to an orthogonal frequency division multiplexing (OFDM) system in LTE, an OFDM system in NR, and a future OFDM system and an OFDM-like system, etc.

[0117] In a wireless communication system (for example, the system shown in FIG. 1a or FIG. 1b), wireless communication sensing fusion is one of the key technologies currently studied by communication networks, and can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude, intelligent network, etc. Communication sensing fusion realizes unified design of communication and sensing functions through signal joint design, hardware sharing, etc. The sensing in communication sensing fusion can be understood as a wireless sensing technology based on a communication system. For example, a terminal device or a network device transmits a wireless signal to a target area or an object and receives a reflected echo signal of the object, and obtains a corresponding sensing result (for example, the number, position, moving speed, and identity of the target object) through analysis of the received signal. Optionally, the target object can be an active object or a passive object, for example, the target object can be replaced by a sensing object, a scatterer, a target, an object, or an obstacle, etc., which is not limited here.

[0118] In other words, in addition to providing communication services, future communication systems can also provide sensing services. Such a network can be understood as an integrated sensing and communication (ISAC) network. However, for a communication device, how to implement object sensing is a technical problem that needs to be solved.

[0119] As an example, taking an access network device and / or a terminal device as a sensing device as an example, a sensing signal can be transmitted between an access network device and a terminal device, between terminal devices, and between access network devices. The following will be described with reference to the process shown in FIG. 2, taking a target object as a vehicle as an example.

[0120] As shown in FIG. 2, the sensing signal can have the following six modes:

[0121] (a) The access network device transmits a sensing signal, and the access network device receives the sensing signal.

[0122] (b) The terminal device transmits a sensing signal, and the terminal device receives the sensing signal.

[0123] (c) One access network device transmits a sensing signal, and another access network device receives the sensing signal.

[0124] (d) One terminal device transmits a sensing signal, and another terminal device receives the sensing signal.

[0125] (e) The access network device transmits a sensing signal, and the terminal device receives the sensing signal.

[0126] (f) The terminal device transmits a sensing signal, and the access network device receives the sensing signal.

[0127] In some embodiments, a communication device can transmit signals using mobile service spectrum, some communication devices can obtain communication services through signal transmission, and some communication devices can obtain perception services through signal transmission. However, when both signals of communication services and signals of perception services are transmitted through mobile service spectrum, the two services will inevitably interfere with each other, thereby affecting the perception performance. Therefore, how to improve the perception performance has not yet been solved.

[0128] To solve the above problems, the present application provides a communication method and related devices, which will be described in detail below in conjunction with the accompanying drawings.

[0129] Please refer to FIG. 3, which is an implementation schematic diagram of the communication method provided by the present application. The method includes the following steps.

[0130] It should be understood that, in the following, the first communication device and the second communication device in FIG. 3 are taken as an example to illustrate the execution subject of the interaction, but the present application does not limit the execution subject of the interaction. For example, the first communication device and / or the second communication device can be a communication device, or a chip, a baseband chip, a modem chip, a system on chip (SoC) chip containing a modem core, a system in package (SIP) chip, a communication module, a chip system, a processor, a logic module or software in the communication device, etc. Optionally, the communication device can be a terminal device or a network device (for example, the network device can be an access network device, an access network element, etc.).

[0131] S301. The first communication device transmits a first signal, and correspondingly, the second communication device receives the first signal. The first signal is used for perception. The first frequency band is different from the second frequency band. The second frequency band is located in the mobile service spectrum, and part or all of the first frequency band is located in the radio positioning service spectrum.

[0132] S302. The second communication device determines a perception result based on the first signal.

[0133] It should be understood that the mobile service spectrum can refer to a spectrum used for mobile communications, including but not limited to an international mobile telecommunications (IMT) spectrum, or a wireless access system / radio local area network (WAS / RLAN) spectrum, etc. For example, the IMT spectrum can include one or more of 3400 megahertz (MHz) to 3800 MHz, 7125 MHz to 8400 MHz, 10 gigahertz (GHz) to 10.5 GHz.

[0134] It should be understood that the radio location service spectrum can be replaced by other implementations different from the mobile service spectrum, such as an amateur service spectrum, or a fixed service (FS) spectrum, etc. For example, the radio location service spectrum can include one or more of 2900 MHz to 3400 MHz, 8500 MHz to 10 GHz.

[0135] In this application, the frequency band can be replaced by other terms, such as a frequency spectrum, a frequency band, a frequency domain, a frequency domain resource, a frequency spectrum resource, a frequency, a frequency interval, a frequency resource, or a channel, etc. For example, the first frequency band can be replaced by the first frequency spectrum, the first frequency band, the first frequency domain, the first frequency domain resource, the first frequency spectrum resource, the first frequency, the first frequency interval, the first frequency resource, or the first channel, etc. For another example, the second frequency band can be replaced by the second frequency spectrum, the second frequency band, the second frequency domain, the second frequency domain resource, the second frequency spectrum resource, the second frequency, the second frequency interval, the second frequency resource, or the second channel, etc.

[0136] Similarly, in this application, the frequency spectrum can be replaced by other terms, such as a frequency band, a frequency domain, a frequency domain resource, a frequency spectrum resource, a frequency, or a frequency resource, etc. For example, the mobile service spectrum can be replaced by the mobile service frequency band, the mobile service frequency band, the mobile service frequency domain, the mobile service frequency domain resource, the mobile service frequency spectrum resource, the mobile service frequency, or the mobile service frequency resource, etc. For another example, the radio location service spectrum can be replaced by the radio location service frequency band, the radio location service frequency band, the radio location service frequency domain, the radio location service frequency domain resource, the radio location service frequency spectrum resource, the radio location service frequency, or the radio location service frequency resource, etc.

[0137] It is to be understood that a signal (e.g., the first signal) for sensing can be understood as being transmitted by a transmitting device, and after reaching a receiving device via a backscattered signal formed by collision (e.g., at least one of reflection, diffraction, or scattering) with various obstacles in a physical space, the receiving device can obtain a sensing result based on the received backscattered signal.

[0138] Optionally, the transmitting device and the receiving device can be the same device (e.g., the first communication device can receive the first signal, a backscattered signal of the first signal, or a reflected signal, etc.), or can be different devices (e.g., the second communication device can receive the first signal, a backscattered signal of the first signal, or a reflected signal, etc.).

[0139] Optionally, a sensing result obtained by a signal (e.g., the first signal) can be used for sensing (or for reflecting) one or more of obstacle information of the signal in a physical space, transmission channel information formed by collision with obstacles, or transmission path information.

[0140] Exemplarily, a sensing result can include one or more of positioning, measurement, detection, channel sensing, monitoring, tracking, time measurement, distance measurement, angle measurement, speed measurement, Doppler shift measurement, point cloud measurement, or sensing feedback. Correspondingly, the sensing result can be applied to one or more of environmental sensing, target identification, target positioning and tracking, or target imaging. The environmental sensing can include one or more of geographical position, distance, speed, angle, map, pose, scale, imaging, or material, etc.

[0141] It is to be noted that a signal (e.g., the first signal) for sensing can be referred to as a sensing signal, a reflected signal, a sensing feedback signal, a sensing response signal, a detection signal, or a radar signal, etc.

[0142] Optionally, the first frequency band being different from the second frequency band can include that a center frequency point of the first frequency band is different from a center frequency point of the second frequency band, and / or a bandwidth of the first frequency band is different from a bandwidth of the second frequency band.

[0143] In some embodiments, the first frequency band and the second frequency band satisfy any one of the following modes A to C.

[0144] Mode A. The second frequency band is contained in the first frequency band.

[0145] Mode B. The second frequency band partially overlaps with the first frequency band.

[0146] Mode C. The second frequency band is spaced apart from the first frequency band by 0 or 1 or more frequency domain units.

[0147] The following will provide some examples to describe the mode A to mode C.

[0148] It should be noted that any one of the first frequency band and the second frequency band can include one or more continuous frequency ranges, and in the following examples, the second frequency band includes one continuous frequency range, and the first frequency band includes one or more continuous frequency ranges.

[0149] As shown in FIG. 4a, it is an example of mode A. In FIG. 4a, the first frequency band and the second frequency band each include a continuous frequency range, wherein the starting frequency point of the first frequency band and the second frequency band is the same, and the ending frequency point of the two is different.

[0150] As shown in FIG. 4b, it is another example of mode A. In FIG. 4b, the first frequency band and the second frequency band each include a continuous frequency range, wherein the ending frequency point of the first frequency band and the second frequency band is the same, and the starting frequency point of the two is different.

[0151] As shown in FIG. 4c, it is another example of mode A. In FIG. 4c, the first frequency band and the second frequency band each include a continuous frequency range, wherein the ending frequency point and the starting frequency point of the first frequency band and the second frequency band are different.

[0152] As shown in FIG. 4d, it is another example of mode A. In FIG. 4d, the second frequency band includes a continuous frequency range, and the first frequency band includes two continuous frequency ranges (i.e. the first frequency band_1 and the first frequency band_2 in the figure), the starting frequency point of the first frequency band_1 and the second frequency band is the same, and the ending frequency point of the first frequency band_1 and the second frequency band is different (which can also be the same), and the first frequency band_2 and the second frequency band have no common frequency range.

[0153] In mode A, the relationship between the second frequency band shown in FIG. 4d and any one of the first frequency band_1 and the first frequency band_2 can also refer to the implementation of FIGS. 4a to 4c described above, which will not be repeated here.

[0154] Optionally, the above frequency point can be replaced by other terms, such as frequency, frequency unit, or frequency domain unit, etc.

[0155] As shown in FIG. 4e, it is an example of mode B. In FIG. 4e, the first frequency band and the second frequency band each include a continuous frequency range, wherein the second frequency band includes a frequency band A not included in the first frequency band, and the first frequency band includes a frequency band B not included in the second frequency band.

[0156] As shown in FIG. 4f, it is another example of mode B. In FIG. 4f, the first frequency band and the second frequency band each include a continuous frequency range, wherein the second frequency band includes a frequency band C not included in the first frequency band, and the first frequency band includes a frequency band D not included in the second frequency band.

[0157] As shown in FIG. 4g, another example of the manner B. In FIG. 4g, the second frequency band contains one continuous frequency range, and the first frequency band contains two continuous frequency ranges (i.e., the first frequency band_1 and the first frequency band_2 in the figure), the second frequency band contains the frequency band E which is not contained by the first frequency band_1, the first frequency band_1 contains the frequency band D which is not contained by the second frequency band, and the first frequency band_2 and the second frequency band do not have a common frequency range.

[0158] It can be understood that, in the manner B, the relationship between the second frequency band shown in FIG. 4g and any one of the first frequency band_1 and the first frequency band_2 can also refer to the implementation of FIGS. 4e to 4f described above, which will not be repeated here.

[0159] As shown in FIG. 4h, an example of the manner C. In FIG. 4h, the first frequency band and the second frequency band each contain one continuous frequency range, wherein the terminal frequency point of the second frequency band is spaced apart from the starting frequency point of the first frequency band by 0 frequency units, i.e., the two frequency points can be the same frequency point.

[0160] As shown in FIG. 4i, another example of the manner C. In FIG. 4i, the first frequency band and the second frequency band each contain one continuous frequency range, wherein the terminal frequency point of the first frequency band is spaced apart from the starting frequency point of the second frequency band by 0 frequency units, i.e., the two frequency points can be the same frequency point.

[0161] As shown in FIG. 4j, another example of the manner C. In FIG. 4j, the first frequency band contains two continuous frequency ranges (i.e., the first frequency band_1 and the first frequency band_2 in FIG. 4j), wherein the terminal frequency point of the first frequency band_1 is spaced apart from the starting frequency point of the second frequency band by 0 frequency units, i.e., the two frequency points can be the same frequency point; and the starting frequency point of the first frequency band_2 is spaced apart from the terminal frequency point of the second frequency band by 0 frequency units, i.e., the two frequency points can be the same frequency point.

[0162] It can be understood that, in the manner C, the relationship between the second frequency band shown in FIG. 4j and any one of the first frequency band_1 and the first frequency band_2 can also refer to the implementation of FIGS. 4h to 4i described above, which will not be repeated here.

[0163] As shown in FIG. 4k, another example of the manner C. In FIG. 4k, the first frequency band and the second frequency band each contain one continuous frequency range, wherein the terminal frequency point of the first frequency band is spaced apart from the starting frequency point of the second frequency band by a frequency range G, which can be one or more frequency units, which can include one or more of, for example, a subcarrier, a subcarrier group, a resource block, a physical resource block, a resource block group, a partial bandwidth, and the like.

[0164] As shown in FIG. 4l, another example of the manner C is shown. In FIG. 4l, the first frequency range contains two continuous frequency ranges (i.e., the first frequency range_1 and the first frequency range_2 in FIG. 4l), wherein the terminal frequency point of the first frequency range_1 is spaced apart from the starting frequency point of the second frequency range by a frequency range H, which can be one or more frequency units; and the starting frequency point of the first frequency range_2 is spaced apart from the terminal frequency point of the second frequency range by a frequency range I, which can be one or more frequency units.

[0165] It can be understood that, in the manner C, the relationship between the second frequency range shown in FIG. 4l and any one of the first frequency range_1 and the first frequency range_2 can also refer to the implementation of FIGS. 4h-4i described above, which will not be described herein.

[0166] It can be understood that, in the above examples, the second frequency range contains one continuous frequency range is taken as an example, in actual application, the second frequency range can contain two or more continuous frequency ranges, and the specific implementation can refer to the foregoing description. Similarly, in the above examples, the first frequency range contains one or two continuous frequency ranges is taken as an example, in actual application, the first frequency range can contain two or more continuous frequency ranges, and the specific implementation can refer to the foregoing description.

[0167] Based on the scheme shown in FIG. 3, the first signal for sensing sent by the first communication device in S301 is borne in the first frequency range, which is different from the second frequency range. Wherein, the second frequency range is located in the mobile service spectrum, and part or all of the first frequency range is located in the radio positioning service spectrum. In other words, part or all of the sensing signal can be borne in the radio positioning service spectrum. Thus, different communication devices can utilize the radio positioning service spectrum to implement the transmission of the sensing signal, and can avoid or reduce the interference of the communication signal transmitted on the mobile service spectrum on the sensing signal, so as to improve the sensing performance.

[0168] Optionally, the bandwidth of the first frequency range can be greater than the bandwidth of the second frequency range. Since the size of the sensing bandwidth is positively correlated with the level of the sensing performance (for example, increasing the sensing bandwidth can improve the sensing resolution, and can implement more fine-grained distance sensing; for another example, increasing the sensing bandwidth can obtain more sensing data acquisition, and can obtain more sensing information), therefore, different communication devices can utilize the first frequency range to implement the transmission of the sensing signal, so as to further improve the sensing performance.

[0169] Optionally, in the method shown in FIG. 3, after the second communication device determines the sensing result in S302, the second communication device can also send indication information indicating the sensing result to other communication devices, for example, the other communication devices can be the first communication device, or an access network element, a core network element and the like with a sensing function.

[0170] It should be noted that the method shown in FIG. 3 can be applied to various sensing scenarios, which will be described below in combination with some implementation examples.

[0171] Example one, the method shown in FIG. 3 can be applied to a self-sensing (or mono-static sensing) scenario, i.e., the first communication device and the second communication device can be the same device.

[0172] As an implementation example, the first communication device and the second communication device are the same device. For example, the first communication device and the second communication device can be the access network device in the (a) scenario shown in FIG. 2. For another example, the first communication device and the second communication device can be the terminal device in the (b) scenario shown in FIG. 2. For another example, the first communication device and the second communication device can be a network element with sensing function, including an access network element, a core network element, or a server, etc.

[0173] Example two, the method shown in FIG. 3 can be applied to a multi-static sensing (or Bi / Multi-static sensing) scenario, i.e., the first communication device and the second communication device can be different devices.

[0174] As an implementation example, the first communication device and the second communication device can both be network devices, for example, the first communication device and the second communication device can be the two access network devices in the (c) scenario shown in FIG. 2.

[0175] As an implementation example, the first communication device and the second communication device can both be terminal devices, for example, the first communication device and the second communication device can be the two terminal devices in the (d) scenario shown in FIG. 2.

[0176] As an implementation example, the first communication device can be a network device, and the second communication device can be a terminal device, for example, the first communication device can be the access network device in the (e) scenario shown in FIG. 2, and the second communication device can be the terminal device in the (e) scenario shown in FIG. 2.

[0177] As an implementation example, the first communication device can be a terminal device, and the second communication device can be an access network device, for example, the first communication device can be the terminal device in the (f) scenario shown in FIG. 2, and the second communication device can be the access network device in the (f) scenario shown in FIG. 2.

[0178] Optionally, the number of second communication devices can be one or more. That is, the above scheme can be applied to a one-to-many receiving scenario. Wherein, in the case that the number of second communication devices is more than one, the second communication devices can include one or more terminal devices, and / or one or more network devices.

[0179] For example, in the (c) or (f) scenario shown in Fig. 2, the second communication device can include one or more terminal devices, and / or one or more network devices, in addition to including the certain access network device.

[0180] For example, in the (d) or (e) scenario shown in Fig. 2, the second communication device can include one or more terminal devices, and / or one or more network devices, in addition to including the certain terminal device.

[0181] In a possible implementation, as shown in Fig. 4m, the method shown in Fig. 3 further includes:

[0182] Step A. The second communication device sends first information, and correspondingly, the first communication device receives the first information. The first information is used to indicate the first frequency band.

[0183] In step A, the first communication device can receive the first information used to indicate the first frequency band, so that the first communication device can implement the sending of the sensing signal based on the indication of the sender of the first information, and further so that the receiver of the sensing signal can obtain the sensing result on the specified first frequency band.

[0184] Optionally, before step A, the method shown in Fig. 4m further includes:

[0185] Step B. The first communication device sends second information, and correspondingly, the second communication device receives the second information. The second information is used to request the first information.

[0186] In step B, the first communication device can send the second information used to request the first information, so that the receiver of the second information can send the first information to the first communication device based on the request, and so that the above sensing process can be adapted to the request of the first communication device.

[0187] As an example, the second information indicates at least one of the following: a frequency band supported by the first communication device, a signal transmission power range supported by the first communication device, a signal reception power range supported by the first communication device, a signal waveform supported by the first communication device, or a signal modulation mode supported by the first communication device.

[0188] In other words, the receiver of the second information can obtain the signal processing mode supported by the first communication device based on the at least one of the above, so that the receiver of the second information can indicate the first frequency band based on the signal processing mode supported by the first communication device, to avoid or reduce the situation that the first communication device cannot perform sensing based on the specified frequency band.

[0189] In a possible implementation, the process in which the first communication apparatus sends the second information in step A includes: in the case that the first condition is met, the first communication apparatus sends the second information; the first condition includes at least one of the following:

[0190] The first communication apparatus receives or sends a second signal, and the second signal is carried in the second frequency band; wherein the second signal is used to determine the first sensing result and the performance of the first sensing result is lower than or equal to a first threshold value;

[0191] The first communication apparatus receives second information, and the second information indicates that the performance of the first sensing result is lower than or equal to a second threshold value; or

[0192] The first communication apparatus determines that the performance corresponding to the signal interference information of the second frequency band is lower than or equal to a third threshold value.

[0193] Specifically, in the case that the first condition is met, the first communication apparatus can determine that the current sensing performance is poor, and for this purpose, the first communication apparatus can send, in step B, second information used to request first information, so as to improve the sensing performance through the first frequency band indicated by the first information.

[0194] Optionally, in addition to the above-mentioned first condition, the first communication apparatus can also trigger the sending of the second information based on other manners. For example, the first communication apparatus sends the second information based on a configured or pre-configured period.
