Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] Wireless communication can be a transmission communication between two or more communication nodes that does not propagate through conductors or cables. Generally, the communication node may include one or more network devices, and / or one or more terminal devices.

[0003] Currently, in communication systems, communication equipment can calculate and determine signal transmission resources, and transmit and receive signals on those resources. These transmission resources may include time-domain resources, frequency-domain resources, etc., used to carry signals. In this way, different communication devices can transmit service data related to communication services through the communication system to obtain communication services.

[0004] With the development of communication technology, future communication systems may provide not only communication services but also sensing services. However, for communication devices, how to achieve object sensing is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides a communication method and related apparatus for improving sensing performance.

[0006] The first aspect of this application provides a communication method executed by a first communication device. The first communication device can be a communication equipment (such as a terminal device or network device), or it can be a component of the communication equipment (e.g., a circuit or chip responsible for communication functions (such as a modem chip, a system-on-chip (SoC) chip, such as an SoC chip containing a modem core, or a system-in-package (SIP) chip)). Alternatively, the first communication device can also be a logic module or software capable of implementing all or part of the functions of the communication equipment. In this method, the first communication device determines a first signal carried in a first frequency band for sensing purposes; wherein the first frequency band is different from a 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 location service (RLS) spectrum; the first communication device transmits the first signal.

[0007] Based on the above scheme, the first signal for sensing transmitted by the first communication device is carried in a first frequency band, which is different from the second frequency band. The second frequency band is located in the mobile service spectrum, while part or all of the first frequency band is located in the radio positioning service spectrum. In other words, part or all of the sensing signal can be carried in the radio positioning service spectrum. Therefore, different communication devices can utilize the radio positioning service spectrum to transmit the sensing signal, avoiding or reducing interference from communication signals transmitted on the mobile service spectrum, thereby improving sensing performance.

[0008] Optionally, the bandwidth of the first frequency band can be greater than that of the second frequency band. Since the size of the sensing bandwidth is positively correlated with the level of sensing performance (for example, increasing the sensing bandwidth can improve the sensing resolution and enable finer-grained distance sensing; also, increasing the sensing bandwidth can obtain more sensing data and more sensing information), different communication devices can use the first frequency band to transmit sensing signals in order to further improve sensing performance.

[0009] It should be understood that mobile service spectrum can refer to the spectrum used for wireless communication, including but not limited to the spectrum of the International Mobile Telecommunications (IMT) system or the spectrum of the Wireless Access System / Radio Local Area Network (WAS / RLAN).

[0010] It should be understood that the radio positioning service spectrum can be replaced with other implementations different from the mobile service spectrum, such as amateur service spectrum or fixed services (FS) spectrum.

[0011] In this application, "frequency band" can be replaced with other terms, such as spectrum, frequency band, frequency domain, frequency domain resource, spectrum resource, frequency, frequency interval, frequency resource, or channel. For example, "first frequency band" can be replaced with "first spectrum," "first frequency band," "first frequency domain," "first frequency domain resource," "first spectrum resource," "first frequency," "first frequency interval," "first frequency resource," or "first channel." Similarly, "second frequency band" can be replaced with "second spectrum," "second frequency band," "second frequency domain," "second frequency domain resource," "second spectrum resource," "second frequency," "second frequency interval," "second frequency resource," or "second channel."

[0012] Similarly, in this application, "spectrum" can be replaced with other terms, such as frequency band, frequency zone, frequency domain, frequency domain resources, spectrum resources, frequency, or frequency resources. For example, "mobile service spectrum" can be replaced with "mobile service frequency band," "mobile service frequency zone," "mobile service frequency domain," "mobile service frequency domain resources," "mobile service spectrum resources," "mobile service frequency," or "mobile service frequency resources." As another example, "radio positioning service spectrum" can be replaced with "radio positioning service frequency band," "radio positioning service frequency zone," "radio positioning service frequency domain," "radio positioning service frequency domain resources," "radio positioning service spectrum resources," "radio positioning service frequency," or "radio positioning service frequency resources."

[0013] It should be understood that a signal (e.g., a first signal) used for sensing can be understood as the signal being sent by a transmitting device and, after being transmitted by an echo signal formed by collisions with various obstacles in physical space (e.g., at least one of reflection, diffraction, or scattering), reaching a receiving device, the receiving device can obtain a sensing result based on the received echo signal.

[0014] Optionally, the transmitting device and the receiving device can be the same device (for example, the first communication device can receive the first signal, the echo signal of the first signal, or the reflected signal, etc.), or they can be different devices (for example, the second communication device can receive the first signal, the echo signal of the first signal, or the reflected signal, etc.).

[0015] Optionally, the perception results obtainable by a signal (e.g., a first signal) are used to perceive (or reflect) one or more of the following: obstacle information in physical space, transmission channel information formed by collision with an obstacle, or transmission path information.

[0016] For example, the perception results may include one or more of the following: localization, measurement, detection, channel sensing, monitoring, tracking, time measurement, distance measurement, angle measurement, velocity measurement, Doppler frequency shift measurement, point cloud measurement, or perception feedback. Correspondingly, these perception results can be applied to various services, such as environmental perception, target recognition, target localization and tracking, or target imaging, one or more of the following. Environmental perception may include one or more of the following: geographic location, distance, velocity, angle, map, attitude, scale, imaging, or material.

[0017] It should be noted that the signal used for sensing (e.g., the first signal) can be called a sensing signal, a reflected signal, a sensing feedback signal, a sensing response signal, a detection signal, or a radar signal, etc.

[0018] Optionally, the first frequency band being different from the second frequency band may include: the center frequency of the first frequency band being different from the center frequency of the second frequency band, and / or the bandwidth of the first frequency band being different from the bandwidth of the second frequency band.

[0019] In one possible implementation of the first aspect, the method further includes: the first communication device receiving first information, the first information being used to indicate the first frequency band.

[0020] Based on the above scheme, the first communication device can receive first information for indicating the first frequency band, so that the first communication device can transmit the sensing signal based on the instruction of the sender of the first information, thereby enabling the receiver of the sensing signal to obtain the sensing result on the designated first frequency band.

[0024] Based on the above scheme, the recipient of the second information can obtain the signal processing method supported by the first communication device based on at least one of the above methods, so that the recipient of the second information can indicate the first frequency band based on the signal processing method supported by the first communication device, thereby avoiding or reducing the situation where the first communication device cannot sense based on the specified frequency band.

[0025] In one possible implementation of the first aspect, the first communication device sending the second information includes: the first communication device sending the second information when a first condition is met; the first condition includes at least one of the following:

[0027] The first communication device receives second information, which indicates that the performance of the first sensing result is lower than or equal to a second threshold; or

[0028] The first communication device determines that the performance corresponding to the signal interference information of the second frequency band is lower than or equal to a third threshold.

[0029] Based on the above scheme, if the first condition is met, the first communication device can determine that the current sensing performance is poor. Therefore, the first communication device can send second information to request first information in order to improve the sensing performance through the first frequency band indicated by the first information.

[0030] Optionally, in addition to the first condition mentioned above, the first communication device may also trigger the transmission of the second information based on other methods. For example, the first communication device may transmit the second information based on a configured or pre-configured period. Alternatively, the first communication device may transmit the second information when its local idle computing power and / or battery power are above a threshold.

[0031] Optionally, the performance of the sensing result can indicate the quality of the sensing result. For example, the performance of the sensing result can indicate at least one of the accuracy, precision, or sensitivity of the sensing result. Accordingly, the threshold of the sensing performance (e.g., at least one of the first threshold, the second threshold, and the fourth and fifth thresholds described below) can be one or more of the accuracy threshold, precision threshold, or sensitivity threshold.

[0032] Optionally, the above-mentioned perception results may include at least one of the following: positioning measurement results, distance measurement results, and angle measurement results.

[0038] The first communication device determines that the signal interference information of the second frequency band is lower than or equal to the sixth threshold.

[0039] Based on the above scheme, if the second condition is met, the first communication device can determine that the current sensing performance is poor. Therefore, the first communication device can send a first signal carried in the first frequency band to improve the sensing performance through the first frequency band.

[0040] Optionally, different perceived performance thresholds (e.g., two or more of the first threshold, second threshold, third threshold, or fourth threshold) can be the same or different.

[0041] Optionally, the performance thresholds (e.g., the third threshold and the sixth threshold) corresponding to different signal interference information can be the same or different.

[0042] Optionally, in addition to the second condition mentioned above, the first communication device may also trigger the transmission of the first signal in other ways. For example, the first communication device may transmit the first signal based on a configured or pre-configured period. Alternatively, the first communication device may transmit the first signal when its local idle computing power and / or battery power are above a threshold.

[0043] In one possible implementation of the first aspect, the method further includes: the first communication device transmitting third information, the third information being used to indicate the first frequency band.

[0044] Based on the above scheme, the first communication device can also send third information, enabling the recipient of the third information to clearly identify the first frequency band carrying the first signal. For example, the recipient of the third information can receive the first signal based on the first frequency band indicated by the third information to obtain the sensing result of the first signal. Furthermore, the recipient of the third information can manage or schedule the sensing frequency bands of one or more first communication devices based on the first frequency band indicated by the third information.

[0045] In one possible implementation of the first aspect, any of the following is satisfied:

Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN.

[0096] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CUs (control plane, CP), CUs (user plane, UP), or radio units (RUs). CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0097] 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 open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU.

Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0104] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0105] (3) Configuration and Pre-configuration: In this application, both configuration and pre-configuration are used. Configuration refers to the network device sending configuration information or parameter values ​​of some parameters to the terminal device through messages or signaling, so that the terminal device can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​that the network device and the terminal device have negotiated in advance, or it can be parameter information or parameter values ​​that the network device or the terminal device uses as specified by the standard protocol, or it can be parameter information or parameter values ​​that are pre-stored in the network device or the terminal device. This application does not limit this.

[0106] Furthermore, these values ​​and parameters can be changed or updated.

[0107] (4) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0108] (5) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY through the air interface or receiving indirectly from YY through the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0109] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0110] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0111] (6) In the embodiments of this application, "instruction" may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is an association between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts of the information to be instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0112] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The embodiments described below do not constitute a limitation on the scope of protection of this application.

[0113] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0114] Please see Figure 1a This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 1a As shown, the communication system includes RAN 100 and core network 200. Optionally, the communication system 1000 may also include Internet 300. RAN 100 includes at least one RAN node (e.g., Figure 1a 110a and 110b, collectively referred to as 110, may also include at least one terminal (such as...). Figure 1aRAN 100, denoted as RAN 120a-120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1a (Not shown in the image). Terminal 120 connects wirelessly to RAN node 110, and RAN node 110 connects wirelessly or via a wired connection to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminals can connect to each other, and RAN nodes can connect to each other, via wired or wireless connections.

[0115] Figure 1b An example diagram of an O-RAN system is shown, which may include other components besides those shown in the diagram. As illustrated, the access network device (RAN, such as an eNB, gNB, or next-generation access network device) communicates with the core network (CN) via a backhaul link and with the UE via an air interface.

[0116] In one possible implementation, this application can be applied to long-term evolution (LTE) wireless communication systems, NR wireless communication systems, and future new radio (NR) wireless communication systems. For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, future OFDM systems, and OFDM-like systems.

[0117] In wireless communication systems (e.g.) Figure 1a or Figure 1b In the system shown, wireless communication sensing fusion is one of the key technologies in current communication network research, and it can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude airspace, and intelligent networks. Communication sensing fusion achieves unified design of communication and sensing functions through signal joint design and hardware sharing. Sensing in communication sensing fusion can be understood as wireless sensing technology based on the communication system. For example, terminal devices or network devices transmit wireless signals to a target area or object and receive the echo signals reflected by the object. The corresponding sensing results are obtained by analyzing the received signals, such as the number, location, speed, and identification of the target object. Optionally, the target object can be an active or passive object; for example, the target object can be replaced by a sensing object, scatterer, target, object, or obstacle, etc., without limitation here.

[0118] In other words, future communication systems may provide not only communication services but also sensing services; such networks can be understood as integrated sensing and communication (ISAC) networks. However, for communication devices, how to achieve object sensing is a technical problem that urgently needs to be solved.

[0119] As an example, taking access network devices and / or terminal devices as sensing devices, sensing signals may be transmitted between access network devices and terminal devices, between terminal devices, and between access network devices. The following will combine... Figure 2 The process shown is illustrated using a vehicle as an example.

[0120] like Figure 2 As shown, the sensing signal can have the following six modes:

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

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

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

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

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

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

[0127] In some embodiments, communication devices can use mobile service spectrum to transmit signals. Some communication devices can obtain communication services through signal transmission, while others can obtain sensing services. However, when both communication service signals and sensing service signals are transmitted through mobile service spectrum, these two services will inevitably interfere with each other, thus affecting sensing performance. Therefore, there is currently no solution to improve sensing performance.

[0128] To address the aforementioned problems, this application provides a communication method and related apparatus, which will be described in detail below with reference to the accompanying drawings.

[0129] Please see Figure 3 This is a schematic diagram of an implementation of the communication method provided in this application, which includes the following steps.

[0130] It should be understood that in the following text, Figure 3 This application illustrates the method using a first and a second communication device as examples of the execution entities in the interactive illustration, but it does not limit the execution entities of this interactive illustration. For example, the first and / or second communication devices can be communication equipment, or chips, baseband chips, modem chips, system-on-chip (SoC) chips containing modem cores, system-in-package (SIP) chips, communication modules, chip systems, processors, logic modules, or software within the communication equipment. Optionally, the communication equipment can be a terminal device or a network device (e.g., the network device can be an access network device, access network element, etc.).

[0131] S301. The first communication device sends a first signal, and correspondingly, the second communication device receives the first signal. The first signal is used for sensing; 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 the sensing result based on the first signal.

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

[0134] It should be understood that the radio positioning service spectrum can be replaced with other implementations different from the mobile service spectrum, such as amateur service spectrum or fixed services (FS) spectrum. For example, the radio positioning service spectrum may include one or more segments of spectrum from 2900MHz to 3400MHz and 8500MHz to 10GHz.

[0135] In this application, "frequency band" can be replaced with other terms, such as spectrum, frequency band, frequency domain, frequency domain resource, spectrum resource, frequency, frequency interval, frequency resource, or channel. For example, "first frequency band" can be replaced with "first spectrum," "first frequency band," "first frequency domain," "first frequency domain resource," "first spectrum resource," "first frequency," "first frequency interval," "first frequency resource," or "first channel." Similarly, "second frequency band" can be replaced with "second spectrum," "second frequency band," "second frequency domain," "second frequency domain resource," "second spectrum resource," "second frequency," "second frequency interval," "second frequency resource," or "second channel."

[0136] Similarly, in this application, "spectrum" can be replaced with other terms, such as frequency band, frequency zone, frequency domain, frequency domain resources, spectrum resources, frequency, or frequency resources. For example, "mobile service spectrum" can be replaced with "mobile service frequency band," "mobile service frequency zone," "mobile service frequency domain," "mobile service frequency domain resources," "mobile service spectrum resources," "mobile service frequency," or "mobile service frequency resources." As another example, "radio positioning service spectrum" can be replaced with "radio positioning service frequency band," "radio positioning service frequency zone," "radio positioning service frequency domain," "radio positioning service frequency domain resources," "radio positioning service spectrum resources," "radio positioning service frequency," or "radio positioning service frequency resources."

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

[0138] Optionally, the transmitting device and the receiving device can be the same device (for example, the first communication device can receive the first signal, the echo signal of the first signal, or the reflected signal, etc.), or they can be different devices (for example, the second communication device can receive the first signal, the echo signal of the first signal, or the reflected signal, etc.).

[0139] Optionally, the perception results obtainable by a signal (e.g., a first signal) are used to perceive (or reflect) one or more of the following: obstacle information in physical space, transmission channel information formed by collision with an obstacle, or transmission path information.

[0140] For example, the perception results may include one or more of the following: localization, measurement, detection, channel sensing, monitoring, tracking, time measurement, distance measurement, angle measurement, velocity measurement, Doppler frequency shift measurement, point cloud measurement, or perception feedback. Correspondingly, these perception results can be applied to various services, such as environmental perception, target recognition, target localization and tracking, or target imaging, one or more of the following. Environmental perception may include one or more of the following: geographic location, distance, velocity, angle, map, attitude, scale, imaging, or material.

[0141] It should be noted that the signal used for sensing (e.g., the first signal) can be called 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 may include: the center frequency of the first frequency band being different from the center frequency of the second frequency band, and / or the bandwidth of the first frequency band being different from the 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 methods A to C.

[0144] Method A. The second frequency band is included in the first frequency band.

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

[0146] Method C. The second frequency band is separated from the first frequency band by 0, 1 or more frequency domain units.

[0147] The following examples will describe methods A through C.

[0148] It should be noted that either the first frequency band or the second frequency band may include one or more continuous frequency ranges. In the following example, the second frequency band includes one continuous frequency range, and the first frequency band includes one or more continuous frequency ranges.

[0149] like Figure 4a The image shown is an example of method A. Figure 4a In this system, the first frequency band and the second frequency band each contain a continuous frequency range. The starting frequency of the first frequency band and the second frequency band are the same, but their ending frequency is different.

[0150] like Figure 4b The image shows another example of method A. Figure 4b In this system, the first frequency band and the second frequency band each contain a continuous frequency range. The first frequency band and the second frequency band have the same ending frequency, but their starting frequencies are different.

[0151] like Figure 4c The image shows another example of method A. Figure 4c In this context, the first frequency band and the second frequency band each contain a continuous frequency range, wherein the ending frequency and the starting frequency of the first frequency band and the second frequency band are different from each other.

[0152] like Figure 4d The image shows another example of method A. Figure 4d In the diagram, the second frequency band contains a 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 diagram). The starting frequency points of the first frequency band_1 and the second frequency band are the same, and the ending frequency points of the first frequency band_1 and the second frequency band are different (or they can be the same). The first frequency band_2 and the second frequency band do not share a common frequency range.

[0153] In method A, Figure 4d The relationship between the second frequency band and any of the first frequency bands_1 and_2, as shown above, can also be referred to the above. Figures 4a to 4c The implementation details are omitted here.

[0154] Optionally, the above frequency points can be replaced with other terms, such as frequency, frequency unit, or frequency domain unit.

[0155] like Figure 4e The image shown is an example of method B. Figure 4e In the above, the first frequency band and the second frequency band each contain a continuous frequency range. The second frequency band includes frequency band A, which is not included in the first frequency band, and the first frequency band includes frequency band B, which is not included in the second frequency band.

[0156] like Figure 4f The image shows another example of method B. Figure 4f In the above, the first frequency band and the second frequency band each contain a continuous frequency range. The second frequency band includes frequency band C, which is not included in the first frequency band, and the first frequency band includes frequency band D, which is not included in the second frequency band.

[0157] like Figure 4g The image shows another example of method B. Figure 4g In the diagram, the second frequency band contains a continuous frequency range, the first frequency band contains two continuous frequency ranges (i.e., the first frequency band_1 and the first frequency band_2 in the diagram), the second frequency band contains the frequency band E that is not included in the first frequency band_1, the first frequency band_1 contains the frequency band D that is not included in the second frequency band, and the first frequency band_2 and the second frequency band do not share a common frequency range.

[0158] Understandably, in method B, Figure 4g The relationship between the second frequency band and any of the first frequency bands_1 and_2, as shown above, can also be referred to the above. Figures 4e to 4f The implementation details are omitted here.

[0159] like Figure 4h The image shown is an example of method C. Figure 4h In this, the first frequency band and the second frequency band each contain a continuous frequency range. The ending frequency of the second frequency band is 0 frequency units away from the starting frequency of the first frequency band, meaning that these two frequency points can be the same frequency point.

[0160] like Figure 4i The image shows another example of method C. Figure 4i In this, the first frequency band and the second frequency band each contain a continuous frequency range. The end frequency of the first frequency band and the start frequency of the second frequency band are separated by 0 frequency units, meaning that these two frequency points can be the same frequency point.

[0161] like Figure 4j The image shows another example of method C. Figure 4j In the first frequency band, there are two consecutive frequency ranges (i.e. Figure 4j The first frequency band_1 and the first frequency band_2 are defined as follows: the end frequency of the first frequency band_1 is 0 frequency units away from the start frequency of the second frequency band, meaning that these two frequency points can be the same frequency point; and the start frequency of the first frequency band_2 is 0 frequency units away from the end frequency of the second frequency band, meaning that these two frequency points can be the same frequency point.

[0162] Understandably, in method C, Figure 4j The relationship between the second frequency band and any of the first frequency bands_1 and_2, as shown above, can also be referred to the above. Figures 4h to 4i The implementation details are omitted here.

[0163] like Figure 4k The image shows another example of method C. Figure 4k In the above, the first frequency band and the second frequency band each contain a continuous frequency range. The frequency range G between the end frequency of the first frequency band and the start frequency of the second frequency band can be one or more frequency units, which can include one or more of the following: subcarrier, subcarrier group, resource block, physical resource block, resource block group, partial bandwidth, etc.

[0164] like Figure 4l The image shows another example of method C. Figure 4l In the first frequency band, there are two consecutive frequency ranges (i.e. Figure 4lThe first frequency band_1 and the first frequency band_2 are in the range of frequency range H between the end frequency of the first frequency band_1 and the start frequency of the second frequency band, where the frequency range H can be one or more frequency units; and the start frequency of the first frequency band_2 is separated from the end frequency of the second frequency band by a frequency range I, where the frequency range I can be one or more frequency units.

[0165] Understandably, in method C, Figure 4l The relationship between the second frequency band and any of the first frequency bands_1 and_2, as shown above, can also be referred to the above. Figures 4h to 4i The implementation details are omitted here.

[0166] It is understandable that, in the above example, the second frequency band is described as containing one continuous frequency range. In practical applications, the second frequency band can contain two or more continuous frequency ranges. For specific implementation details, please refer to the previous description. Similarly, in the above example, the first frequency band is described as containing one or two continuous frequency ranges. In practical applications, the first frequency band can contain two or more continuous frequency ranges. For specific implementation details, please refer to the previous description.

[0167] based on Figure 3 In the illustrated scheme, the first sensing signal transmitted by the first communication device in S301 is carried on a first frequency band, which is different from the second frequency band. The second frequency band is located in the mobile service spectrum, while part or all of the first frequency band is located in the radio positioning service spectrum. In other words, part or all of the sensing signal can be carried in the radio positioning service spectrum. Therefore, different communication devices can utilize the radio positioning service spectrum to transmit the sensing signal, avoiding or reducing interference from communication signals transmitted on the mobile service spectrum, thereby improving sensing performance.

[0168] Optionally, the bandwidth of the first frequency band can be greater than that of the second frequency band. Since the size of the sensing bandwidth is positively correlated with the level of sensing performance (for example, increasing the sensing bandwidth can improve the sensing resolution and enable finer-grained distance sensing; also, increasing the sensing bandwidth can obtain more sensing data and more sensing information), different communication devices can use the first frequency band to transmit sensing signals in order to further improve sensing performance.

[0169] Optional, in Figure 3 In the method shown, 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 access network elements, core network elements, etc. that have sensing functions.

[0170] It should be noted that, Figure 3 The method shown can be applied to various sensing scenarios, and will be introduced below with some implementation examples.

[0171] Example 1, Figure 3 The method shown can be applied to scenarios of self-sensing (or mono-static sensing), that is, 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... Figure 2 The access network equipment in scenario (a) shown. For example, the first communication device and the second communication device can be... Figure 2 The terminal device in scenario (b) shown. For example, the first and second communication devices can be network elements with sensing capabilities, including access network elements, core network elements, or servers, etc.

[0173] Example 2, Figure 3 The method shown can be applied to multi-station sensing (or bi / multi-static sensing) scenarios, where the first communication device and the second communication device can be different devices.

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

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

[0176] As an example of implementation, 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... Figure 2 In the access network equipment shown in scenario (e), the second communication device can be Figure 2 The access device in scenario (e) shown.

[0177] As an example of implementation, 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... Figure 2 In the scenario shown (f), the terminal device and the second communication device can be... Figure 2 The access network equipment in scenario (f) shown.

[0178] Optionally, the number of second communication devices can be one or more. That is, the above scheme can be applied to scenarios where one device transmits and multiple devices receive. Where there are multiple second communication devices, the second communication devices may include one or more terminal devices, and / or one or more network devices.

[0179] For example, in Figure 2 In the scenarios shown in (c) or (f), the second communication device may include, in addition to an access network device, one or more terminal devices and / or one or more network devices.

[0180] For example, in Figure 2 In the scenario shown in (d) or (e), the second communication device may include, in addition to a terminal device, one or more terminal devices and / or one or more network devices.

[0181] In one possible implementation, such as Figure 4m As shown, Figure 3 The method shown also 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 first information for indicating the first frequency band, so that the first communication device can transmit a sensing signal based on the instruction of the sender of the first information, thereby enabling the receiver of the sensing signal to obtain a sensing result on the specified first frequency band.

[0184] Optionally, before step A, Figure 4m The method shown also includes:

[0185] Step B. The first communication device sends the 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 may send second information to request first information, so that the recipient of the second information can send the first information to the first communication device based on the request, and the above-mentioned 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: the frequency band supported by the first communication device, the range of signal transmission power supported by the first communication device, the range of signal reception power supported by the first communication device, the signal waveform supported by the first communication device, or the signal modulation method supported by the first communication device.

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

[0189] In one possible implementation, the process of the first communication device sending the second information in step A includes: the first communication device sending the second information when a first condition is met; the first condition includes at least one of the following:

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

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

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

[0193] Specifically, if the first condition is met, the first communication device can determine that the current sensing performance is poor. Therefore, the first communication device can send second information in step B to request first information in order to improve the sensing performance through the first frequency band indicated by the first information.

[0194] Optionally, in addition to the first condition mentioned above, the first communication device may also trigger the transmission of the second information based on other methods. For example, the first communication device may transmit the second information based on a configured or pre-configured period. Alternatively, the first communication device may transmit the second information when its local idle computing power and / or battery power are above a threshold.

[0195] Optionally, the performance of the sensing result can indicate the quality of the sensing result. For example, the performance of the sensing result can indicate at least one of accuracy, precision, or sensitivity. Accordingly, the sensing performance threshold (e.g., at least one of the first threshold, the second threshold, and the fourth and fifth thresholds described below) can be one or more of the accuracy threshold, precision threshold, or sensitivity threshold. For example, the performance of the sensing result being lower than a certain sensing performance threshold can include at least one of the following: the accuracy of the sensing result is lower than the accuracy threshold, the precision of the sensing result is lower than the precision threshold, or the sensitivity of the sensing result is lower than the sensitivity threshold.

[0196] Optionally, the above-mentioned perception results may include at least one of the following: positioning measurement results, distance measurement results, and angle measurement results.

[0197] Optionally, different performance thresholds (e.g., the first threshold and the second threshold) can be the same or different.

[0198] Optionally, the signal interference information may include one or more of the following: signal and interference plus noise ratio (SINR), interference power, signal-to-noise ratio (SNR), or other interference-related information. Correspondingly, the threshold for the signal interference information (e.g., a third threshold, or a sixth threshold described below) may be one or more of the following: SINR threshold, interference power threshold, or SNR threshold. For example, a performance level corresponding to the signal interference information being lower than a certain performance threshold (e.g., a third threshold, or a sixth threshold described below) may include at least one of the following: the SINR of the sensed signal is lower than the SINR threshold, the interference power of the sensed signal is higher than the interference power threshold, or the SNR of the sensed signal is lower than the SNR threshold.

[0199] In one possible implementation, the process of the first communication device transmitting the first signal in S301 includes: the first communication device transmitting the first signal when a second condition is met; the second condition includes at least one of the following:

[0200] The first communication device receives or transmits a second signal, which is carried in the second frequency band; wherein the second signal is used to determine a first sensing result and the performance of the first sensing result is lower than or equal to a fourth threshold.

[0201] The first communication device receives second information, which indicates that the performance of the first sensing result is lower than or equal to a fifth threshold; or

[0202] The first communication device determines that the signal interference information of the second frequency band is lower than or equal to the sixth threshold.

[0203] Specifically, if the second condition is met, the first communication device can determine that the current sensing performance is poor. Therefore, the first communication device can send a first signal carried in the first frequency band in S301 to improve the sensing performance through the first frequency band.

[0204] Optionally, different performance thresholds (e.g., two or more of the first threshold, second threshold, third threshold, or fourth threshold) can be the same or different.

[0205] Optionally, the thresholds corresponding to different signal interference information (e.g., the third threshold and the sixth threshold) can be the same or different.

[0206] Optionally, if the first threshold is the same as the fourth threshold, the second threshold is the same as the fifth threshold, and the third threshold is the same as the sixth threshold, the first condition and the second condition can be regarded as the same condition.

[0207] Optionally, in addition to the second condition mentioned above, the first communication device may also trigger the transmission of the first signal in other ways. For example, the first communication device may transmit the first signal based on a configured or pre-configured period. Alternatively, the first communication device may transmit the first signal when its local idle computing power and / or battery power are higher than a seventh threshold (which may be the same as or different from any of the aforementioned thresholds).

[0208] In one possible implementation, such as Figure 4m As shown, Figure 3 The method shown also includes:

[0209] Step C. The first communication device sends third information, and correspondingly, the second communication device receives the third information, which is used to indicate the first frequency band.
