[0003] This application relates to the field of communication technology, and in particular to a sensing method and apparatus. Background Technology

[0004] Communication-sensing integration combines wireless communication and sensing functions into a single system. It utilizes the various propagation characteristics of wireless signals to achieve sensing functions such as target localization, detection, imaging, and identification, thereby acquiring information about the surrounding physical environment, improving communication performance, and enhancing user experience. In communication-sensing integration technology, sensing signals can be used to obtain information such as the position and velocity of targets in the environment.

[0005] Currently, the perception performance is poor, so how to improve the perception performance has become an urgent problem to be solved. Summary of the Invention

[0006] This application provides a sensing method to improve sensing performance.

[0007] Firstly, a sensing method is provided, which can be applied to a first device. Optionally, the first device is a terminal-side device, also referred to as a terminal device. The terminal device is, for example, a terminal equipment, or other equipment including terminal equipment functions, or a circuit, or a system-on-a-chip (or chip, such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core or a system-in-package (SIP) chip) or other functional module, which can implement the functions of the terminal equipment, and is, for example, disposed in the terminal equipment. Alternatively, the first device is a network-side device, also referred to as a network device. The network device is, for example, a network device, or other equipment including network device functions, or a circuit, or a system-on-a-chip (or chip) or other functional module, which can implement the functions of the network device, and is, for example, disposed in the network device. The network device includes, for example, core network equipment and / or access network equipment. The method includes: a first device receiving a first sensing signal on a first sensing resource, and receiving a second sensing signal on a second sensing resource, wherein the first sensing signal and the second sensing signal are used to sense target information.

[0008] In this embodiment, the first device can receive two sensing signals on different resources, and perceive target information through the two sensing signals, resulting in better sensing performance. Furthermore, receiving the first and second sensing signals on different resources (e.g., sensing resources) helps reduce the probability of conflict between the first and second sensing signals.

[0009] In the embodiments of this application, the sensing target information can also be referred to as determining target information, running sensing services, or simply performing sensing. The target information can be determined based on the received information of the sensing signal, such as receiving phase and / or receiving amplitude.

[0010] In one possible implementation, the method further includes: the first device transmitting the second sensing signal on the second sensing resource.

[0011] In the above technical solution, transmitting the second sensing signal through the first device helps reduce the number of devices required to sense target information. For example, only the device that transmits the first sensing signal (e.g., the second device) and the first device are needed, without introducing other devices. The first sensing signal transmitted by the first device and the second sensing signal transmitted by the second device can jointly sense the target information.

[0012] In one possible implementation, the first sensing resource includes a first time-domain resource, and the second sensing resource includes a second time-domain resource; wherein the first time-domain resource overlaps with the second time-domain resource; or, the interval between the first time-domain resource and the second time-domain resource is less than a first time interval.

[0013] In the above technical solution, the first time-domain resources and the second time-domain resources overlap, or the interval between the first time-domain resources and the second time-domain resources is less than the first time interval. This makes the arrival times of the first sensing signal and the second sensing signal at the target similar, which can reduce the difference in perceived target information caused by target movement or attitude changes, thereby helping to improve sensing performance. In addition, the interval between the first time-domain resources and the second time-domain resources is less than the first time interval, which means that different time-domain resources can be allocated to the first sensing signal and the second sensing signal, resulting in better resource allocation.

[0014] In one possible implementation, the first time interval is determined based on perceived demand, or the first time interval is determined based on perceived quality of service (QoS), or the first time interval is predefined.

[0015] In the above technical solution, the sensing requirements can be, for example, the target's moving speed, sensing accuracy, etc. The faster the target moves, the shorter the first time interval; the slower the target moves, the longer the first time interval. Or, the higher the sensing accuracy, the shorter the first time interval; the lower the sensing accuracy, the longer the first time interval. Or, the higher the sensing service quality, the longer the first time interval; the lower the sensing service quality, the shorter the first time interval. In this way, resources can be better allocated while ensuring sensing performance.

[0016] In one possible implementation, the first sensing resource includes a first frequency domain resource, and the second sensing resource includes a second frequency domain resource; wherein the first frequency domain resource belongs to a first frequency domain resource set, and the second frequency domain resource belongs to a second frequency domain resource set; or, the first frequency domain resource and the second frequency domain resource belong to different frequency domain units of a third frequency domain resource set.

[0017] In the above technical solution, the first frequency domain resource and the second frequency domain resource belong to different frequency domain resource sets, or the first frequency domain resource and the second frequency domain resource belong to different frequency domain units in the same frequency domain resource set. This can reduce the probability of conflict between the first sensing signal and the second sensing signal, thereby reducing the mutual influence between the first sensing signal and the second sensing signal.

[0018] In one possible implementation, the first frequency domain resource belongs to a first frequency domain resource set, and the second frequency domain resource belongs to a second frequency domain resource set. The first frequency domain resource set and the second frequency domain resource set satisfy at least one of the following relationships: the minimum frequency domain interval between the frequency domain units included in the first frequency domain resource set and the frequency domain units included in the second frequency domain resource set is greater than or equal to the first frequency domain interval; the minimum frequency domain interval between the multiple frequency domain units included in the first frequency domain resource set is greater than or equal to the second frequency domain interval; the minimum frequency domain interval between the multiple frequency domain units included in the second frequency domain resource set is greater than or equal to the third frequency domain interval; the minimum frequency domain interval between the multiple frequency domain units included in the first frequency domain resource set is the same as the minimum frequency domain interval between the multiple frequency domain units included in the second frequency domain resource set; the total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located is the same as the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located; the index of the first frequency domain resource set is different from the index of the second frequency domain resource set; or, the number of frequency domain units included in the first frequency domain resource set is the same as the number of frequency domain units included in the second frequency domain resource set. By using the methods described above, the probability of sensor signal collisions can be reduced.

[0019] In one possible implementation, the index of the first frequency domain resource set is different from the index of the second frequency domain resource set; the index of the second frequency domain resource set is determined based on the total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located and / or the index of the first frequency domain resource set; or, the index of the first frequency domain resource set is determined based on the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located and / or the index of the second frequency domain resource set.

[0020] In the above technical solution, the index of the first frequency domain resource set is related to the index of the second frequency domain resource set and / or the total number of frequency domain resource sets in the time unit where the second frequency domain resource set is located, or the index of the second frequency domain resource set is related to the index of the first frequency domain resource set and / or the total number of frequency domain resource sets in the time unit where the first frequency domain resource set is located. Thus, when configuring resources, only the index of one frequency domain resource set and / or the total number of frequency domain resource sets in the time unit where that frequency domain resource set is located needs to be configured, which helps reduce the transmission overhead of resource configuration information.

[0021] In one possible implementation, the first frequency domain resource and the second frequency domain resource belong to different frequency domain units of a third frequency domain resource set. The multiple frequency domain units of the third frequency domain resource set satisfy at least one of the following relationships: the minimum frequency domain spacing of the multiple frequency domain units of the third frequency domain resource set is greater than or equal to a fourth frequency domain spacing; the minimum frequency domain spacing of the multiple frequency domain units of the first frequency domain resource in the third frequency domain resource set is the same as the minimum frequency domain spacing of the multiple frequency domain units of the second frequency domain resource; the index of the sub-frequency domain resource set corresponding to the first frequency domain resource in the third frequency domain resource set is different from the index of the sub-frequency domain resource set corresponding to the second frequency domain resource; or, the number of frequency domain units of the first frequency domain resource in the third frequency domain resource set is the same as the number of frequency domain units of the second frequency domain resource. By using the above methods, the probability of sensing signal collisions can be reduced.

[0022] In one possible implementation, the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set is different from the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set; the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set is determined based on the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set; or, the index of the first frequency domain resource set is determined based on the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set.

[0023] In the above technical solution, the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set is related to the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set, or the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set is related to the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set. This way, when configuring resources, only the index of one sub-frequency domain resource set needs to be configured, which helps reduce the transmission overhead of resource configuration information.

[0024] In one possible implementation, the third frequency domain resource set includes N1 frequency domain units, where N1 is an integer greater than 1. The first frequency domain resource is the frequency domain unit among the N1 frequency domain units whose index x satisfies x mod M1 = i. The second frequency domain resource is the frequency domain unit among the N1 frequency domain units whose index x satisfies x mod M1 = i. The frequency domain unit M1 = j, where M1 is an integer greater than 1 and less than N1, and i and j are integers greater than or equal to 0 and less than M1, i ≠ j; or, the third frequency domain resource set includes N1 frequency domain units, where N1 is an integer greater than 1, the first frequency domain resource is the frequency domain unit with index x of a·N1 / M1~((a+1)·N1 / M1)-1 among the N1 frequency domain units, the second frequency domain resource is the frequency domain unit with index x of b·N1 / M1~((b+1)·N1 / M1)-1 among the N1 frequency domain units, M1 is an integer greater than 1 and less than N1, and a and b are integers greater than or equal to 0 and less than M1, a ≠ b; or, the third frequency domain resource set includes P1 physical resource blocks, where P1 is an integer greater than 1, and the first frequency domain resource is the frequency domain unit with index y of index y satisfying y mod ... The first frequency domain resource is a physical resource block with index y of M1 = i, where M1 is an integer greater than 1, and i and j are integers greater than or equal to 0 and less than P1, with i ≠ j; or, the third frequency domain resource set includes P1 physical resource blocks, where P1 is an integer greater than 1, the first frequency domain resource is a physical resource block with index y of a·P1 / M1 ~ ((a+1)·P1 / M1)-1, and the second frequency domain resource is a physical resource block with index y of b·P1 / M1 ~ ((b+1)·P1 / M1)-1, where M1 is an integer greater than 1 and less than P1, and a and b are integers greater than or equal to 0 and less than M1, with a ≠ b. By using the above methods, the probability of sensing signal collisions can be reduced.

[0025] Based on the above description, the first and second sensing resources can satisfy any one of the following relationships: Relationship 1: The first time-domain resource overlaps with the second time-domain resource, and the first and second frequency-domain resources belong to different frequency-domain resource sets. That is, the first frequency-domain resource belongs to the first frequency-domain resource set, and the second frequency-domain resource belongs to the second frequency-domain resource set. Relationship 2: The first time-domain resource overlaps with the second time-domain resource, and the first and second frequency-domain resources belong to different frequency-domain units of the same frequency-domain resource set. That is, the first and second frequency-domain resources belong to different frequency-domain units in the third frequency-domain resource set. Relationship 3: The interval between the first and second time-domain resources is less than or equal to the first time interval, and the first and second frequency-domain resources belong to different frequency-domain resource sets. That is, the first frequency-domain resource belongs to the first frequency-domain resource set, and the second frequency-domain resource belongs to the second frequency-domain resource set. Relationship 4: The interval between the first time domain resource and the second time domain resource is less than or equal to the first time interval, and the first frequency domain resource and the second frequency domain resource belong to different frequency domain units of the same frequency domain resource set, that is, the first frequency domain resource and the second frequency domain resource belong to different frequency domain units in the third frequency domain resource set.

[0026] In one possible implementation, receiving a first sensing signal on a first sensing resource and receiving a second sensing signal on a second sensing resource includes: a first sensing receiver of the first device receiving the first sensing signal on the first sensing resource and the first sensing receiver receiving the second sensing signal on the second sensing resource.

[0027] In the above technical solution, the first device can receive two sensing signals on different resources through the same sensing receiver, which can reduce the number of sensing receivers in the first device and save costs. Furthermore, based on the first sensing signal, the second sensing signal can determine different information about the sensing target, thereby improving sensing performance through joint sensing.

[0028] In one possible implementation, the method further includes: a second sensing receiver of the first device receiving the first sensing signal on the first sensing resource; and / or, the second sensing receiver receiving the second sensing signal on the second sensing resource.

[0029] In the above technical solution, the first device receives the same sensing signal through different sensing receivers, which can increase the number of sensing signals received by the first device. Taking the first device receiving the second sensing signal on the second sensing resource through the second sensing receiver as an example, the first device receives one first sensing signal and two second sensing signals, which can determine different information of the sensing target, thereby improving the sensing performance through joint sensing.

[0030] In one possible implementation, receiving a first sensing signal on a first sensing resource and receiving a second sensing signal on a second sensing resource includes: a first sensing receiver of the first device receiving the first sensing signal on the first sensing resource, and a second sensing receiver of the first device receiving the second sensing signal on the second sensing resource.

[0031] In the above technical solution, the first device can receive different sensing signals through different sensing receivers, which can reduce the probability of sensing signal reception conflicts.

[0032] In one possible implementation, the method further includes: the first sensing receiver receiving the second sensing signal on the second sensing resource; and / or, the second sensing receiver receiving the first sensing signal on the first sensing resource.

[0033] In the above technical solution, the first device receives the same sensing signal through different sensing receivers, which can increase the number of sensing signals received by the first device. Taking the first device receiving the second sensing signal on the second sensing resource through the first sensing receiver as an example, the first device receives one first sensing signal and two second sensing signals, which can determine different information of the sensing target, thereby improving the sensing performance through joint sensing.

[0034] In one possible implementation, the first sensing signal and the second sensing signal satisfy at least one of the following relationships: the distance between the transmitting end and the receiving end of the first sensing signal is greater than or equal to k1·λ1; the distance between the transmitting end and the receiving end of the second sensing signal is greater than or equal to k2·λ2; the distance between the receiving end of the first sensing signal and the receiving end of the second sensing signal is greater than or equal to k3·λ1, and the receiving ends of the first and second sensing signals are different; the distance between the receiving end of the first and the receiving ends of the second sensing signal is greater than or equal to k3·λ2, and the receiving ends of the first and second sensing signals are different; wherein k1, k2, and k3 are constants, λ1 is the wavelength of the first sensing signal, and λ2 is the wavelength of the second sensing signal.

[0035] In the above technical solution, the relationship between the first sensing signal and the second sensing signal is only an example. In other embodiments, the first sensing signal and the second sensing signal may also satisfy other relationships, such as the distance between the transmitting end of the first sensing signal and the transmitting end of the second sensing signal being greater than or equal to k7·λ1, or the distance between the transmitting end of the first sensing signal and the transmitting end of the second sensing signal being greater than or equal to k7·λ2. This application embodiment does not limit this.

[0036] The distance between the transmitting and receiving ends of the same sensing signal ensures sufficient propagation distance for the sensing signal, allowing for slight differences between the received and transmitted signals (such as differences in amplitude, phase, and frequency). Considering the measurement error of the first device, k1·λ1 (or k2·λ2, k4·λ3) balances antenna size and sensing performance. The distance between the receiving ends of different sensing signals ensures that the reception of sensing signals does not interfere with each other. Considering the measurement error of the first device, this distance relationship balances antenna size and sensing performance.

[0037] Furthermore, when the same receiving end receives both the first and second sensing signals, the distance relationships based on both the first and second sensing signals can be satisfied, thus ensuring sensing performance. The distance between the transmitting ends of different sensing signals is to ensure that the transmission of sensing signals does not interfere with each other, i.e., to avoid signal coupling problems. Additionally, when the same transmitting end transmits both the first and second sensing signals, the distance relationships based on both the first and second sensing signals can be satisfied, thus ensuring sensing performance.

[0038] In one possible implementation, the method further includes: the first device receiving a third sensing signal on a third sensing resource, the third sensing signal being used to sense the target information.

[0039] In the above technical solution, the first device can receive three sensing signals on different resources, and perceive target information through the three sensing signals. This allows for joint perception of target information and results in better sensing performance. Furthermore, receiving the first, second, and third sensing signals on different resources helps reduce the probability of sensing signal conflicts, thereby minimizing the influence between the sensing signals.

[0040] In one possible implementation, the first sensing resource includes a first time-domain resource, the second sensing resource includes a second time-domain resource, and the third sensing resource includes a third time-domain resource; wherein the first time-domain resource, the second time-domain resource, and the third time-domain resource overlap; or, the interval between any two of the first time-domain resource, the second time-domain resource, and the third time-domain resource is less than or equal to a second time interval.

[0041] In the above technical solution, the first, second, and third time-domain resources overlap, or the interval between any two of the first, second, and third time-domain resources is less than the second time interval. This makes the arrival times of the first, second, and third sensing signals at the target similar, reducing the differences in perceived target information caused by target movement or attitude changes, thereby improving sensing performance. Furthermore, the interval between any two of the first, second, and third time-domain resources is less than the second time interval, meaning different time-domain resources can be allocated to the first, second, and third sensing signals, resulting in better resource allocation.

[0042] In one possible implementation, the second time interval is determined based on perceived demand, or the second time interval is determined based on perceived quality of service (QoS), or the second time interval is predefined.

[0043] In the above technical solution, the sensing requirements can be, for example, the target's moving speed, sensing accuracy, etc. The faster the target moves, the shorter the first time interval; the slower the target moves, the longer the first time interval. Or, the higher the sensing accuracy, the shorter the first time interval; the lower the sensing accuracy, the longer the first time interval. Or, the higher the sensing service quality, the longer the first time interval; the lower the sensing service quality, the shorter the first time interval. In this way, resources can be better allocated while ensuring sensing performance.

[0044] In one possible implementation, the first sensing resource includes a first frequency domain resource, the second sensing resource includes a second frequency domain resource, and the third sensing resource includes a third frequency domain resource; wherein the first frequency domain resource belongs to a first frequency domain resource set, the second frequency domain resource belongs to a second frequency domain resource set, and the third frequency domain resource belongs to a fourth frequency domain resource set; or, the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource belong to different frequency domain units of a fifth frequency domain resource set.

[0045] In the above technical solution, the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource belong to different frequency domain resource sets, or the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource belong to different frequency domain units in the same frequency domain resource set, which can reduce the probability of conflict between the first sensing signal, the second sensing signal, and the third sensing signal.

[0046] In one possible implementation, the first frequency domain resource belongs to a first frequency domain resource set, the second frequency domain resource belongs to a second frequency domain resource set, and the third frequency domain resource belongs to a fourth frequency domain resource set. The first, second, and fourth frequency domain resource sets satisfy at least one of the following relationships: the minimum frequency domain interval between the frequency domain units included in the first and second frequency domain resource sets is greater than or equal to a fifth frequency domain interval; the minimum frequency domain interval between the frequency domain units included in the first and fourth frequency domain resource sets is greater than or equal to a sixth frequency domain interval; the minimum frequency domain interval between the frequency domain units included in the second and fourth frequency domain resource sets is greater than or equal to a seventh frequency domain interval; the minimum frequency domain interval between multiple frequency domain units included in the first frequency domain resource set is greater than or equal to an eighth frequency domain interval; the minimum frequency domain interval between multiple frequency domain units included in the second frequency domain resource set is greater than or equal to... The minimum frequency interval of the multiple frequency units included in the fourth frequency domain resource set is greater than or equal to the tenth frequency domain interval; the minimum frequency intervals of the multiple frequency units included in the first frequency domain resource set, the second frequency domain resource set, and the fourth frequency domain resource set are all the same; the total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located, the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located, and the total number of frequency domain resource sets in the third time unit where the fourth frequency domain resource set is located are all the same; or, the indices of the first frequency domain resource set, the second frequency domain resource set, and the fourth frequency domain resource set are all different, and the number of frequency domain units included in the first frequency domain resource set, the second frequency domain resource set, and the fourth frequency domain resource set are all the same. Through the above methods, the probability of sensing signal collisions can be reduced.

[0047] In one possible implementation, the indices of the first frequency domain resource set, the second frequency domain resource set, and the fourth frequency domain resource set are all different; the index of the fourth frequency domain resource set is determined based on at least one of the following: the total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located, the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located, the index of the first frequency domain resource set, and the index of the second frequency domain resource set; or, the index of the second frequency domain resource set is determined based on at least one of the following: the total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located, the total number of frequency domain resource sets in the third time unit where the fourth frequency domain resource set is located, the index of the first frequency domain resource set, and the index of the fourth frequency domain resource set; or, the index of the first frequency domain resource set is determined based on at least one of the following: the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located, the total number of frequency domain resource sets in the third time unit where the fourth frequency domain resource set is located, the index of the second frequency domain resource set, and the index of the fourth frequency domain resource set.

[0048] In the above technical solution, the index of the first frequency domain resource set is related to at least one of the following: the index of the second frequency domain resource set, the index of the fourth frequency domain resource set, the total number of frequency domain resource sets in the time unit where the second frequency domain resource set is located, and the total number of frequency domain resource sets in the time unit where the fourth frequency domain resource set is located; or, the index of the second frequency domain resource set is related to at least one of the following: the index of the first frequency domain resource set, the index of the fourth frequency domain resource set, the total number of frequency domain resource sets in the time unit where the first frequency domain resource set is located, and the total number of frequency domain resource sets in the time unit where the fourth frequency domain resource set is located; or, the index of the fourth frequency domain resource set is related to at least one of the following: the index of the first frequency domain resource set, the index of the second frequency domain resource set, the total number of frequency domain resource sets in the time unit where the first frequency domain resource set is located, and the total number of frequency domain resource sets in the time unit where the second frequency domain resource set is located. In this way, when configuring resources, only the index of one frequency domain resource set and / or the total number of frequency domain resource sets in the time unit where that frequency domain resource set is located can be configured, which helps to reduce the transmission overhead of resource configuration information.

[0049] In one possible implementation, the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource belong to different frequency domain units of a fifth frequency domain resource set. The multiple frequency domain units of the fifth frequency domain resource set satisfy at least one of the following relationships: the minimum frequency domain spacing of the multiple frequency domain units of the fifth frequency domain resource set is greater than the eleventh frequency domain spacing; the minimum frequency domain spacing of the multiple frequency domain units of the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource in the fifth frequency domain resource set are all the same; the indices of the sub-frequency domain resource sets corresponding to the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource in the fifth frequency domain resource set are all different; or, the number of frequency domain units of the first frequency domain resource, the second frequency domain resource, and the third frequency domain resource in the fifth frequency domain resource set are all the same. By using the above methods, the probability of sensing signal collisions can be reduced.

[0050] In one possible implementation, the indices of the sub-frequency domain resource sets corresponding to the first frequency domain resource set, the second frequency domain resource set, and the fourth frequency domain resource set are all different; the indices of the sub-frequency domain resource sets corresponding to the second frequency domain resource set are determined based on the indices of the sub-frequency domain resource sets corresponding to the first frequency domain resource set and / or the fourth frequency domain resource set; or, the indices of the first frequency domain resource set are determined based on the indices of the sub-frequency domain resource sets corresponding to the second frequency domain resource set and / or the fourth frequency domain resource set; or, the indices of the fourth frequency domain resource set are determined based on the indices of the sub-frequency domain resource sets corresponding to the second frequency domain resource set and / or the first frequency domain resource set.

[0051] In the above technical solution, the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set is related to the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set and / or the index of the sub-frequency domain resource set corresponding to the fourth frequency domain resource set; or, the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set is related to the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set and / or the index of the sub-frequency domain resource set corresponding to the fourth frequency domain resource set; or, the index of the sub-frequency domain resource set corresponding to the fourth frequency domain resource set is related to the index of the sub-frequency domain resource set corresponding to the first frequency domain resource set and / or the index of the sub-frequency domain resource set corresponding to the second frequency domain resource set.

[0175] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0176] In this application embodiment, the number of nouns, unless otherwise specified, refers to "singular nouns or plural nouns," that is, "one or more." "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. 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. For example, A / B means: A or B. "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, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, and c can be single or multiple.

[0177] 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 size, content, order, timing, priority, or importance of the multiple objects. Furthermore, the numbering of steps in the various embodiments described in this application is only to distinguish different steps and is not used to limit the order in which the steps are performed.

[0178] Before introducing the technical solutions provided in the embodiments of this application, the technical terms, applicable network architectures, and scenarios involved in the embodiments of this application will be introduced first.

[0179] (1) Perception can also be replaced by: sensing process, sensing operation, sensing detection, and detection processing.

[0180] Perception can be understood as a technology that can acquire information about the characteristics of the environment and / or objects in the environment. This information includes, but is not limited to, shape, size, orientation, speed, position, distance between objects, or relative motion.

[0181] The working principle of sensing is as follows: the sensing transmitter sends a sensing signal, the sensing receiver receives the sensing signal reflected and / or scattered by the sensing target (also known as the echo signal), and obtains the sensing result, such as position, speed, distance, shape, size, etc., based on the received sensing signal.

[0182] Sensing target: also referred to as target, detected target, sensed object, or sensed object, etc., the embodiments of this application are not limited thereto. The sensing target can be any tangible object in the environment capable of reflecting electromagnetic waves. For example, the sensing target can be a stationary object such as a building. Alternatively, the sensing target can be a mobile object such as a vehicle, drone, person, automated equipment, or terminal device. The sensing target may include one or more scattering points used to deduce the characteristics of the target.

[0183] (2) Sensing signals

[0184] A sensing signal is a signal transmitted over the air interface that can be used to sense a target. It can also be called a signal acting on sensing, a sensing reference signal, or a reference signal used for sensing. Sensing services can be implemented by processing the sensing signal; that is, the sensing signal is used to determine information about the sensing target. The sensing signal can be transmitted alone, or it can be transmitted along with communication signals, or it can be a communication signal used for sensing services. This communication signal can be understood as a reference signal for communication; that is, the sensing signal can be used to perform communication, including transmitting communication data, control information, and measurement results.

[0185] Communication-sensing integration (also known as sensing) is an important technological direction. Communication systems possess sensing capabilities, enabling integrated design of communication and sensing. Communication-sensing integration takes various forms, such as using communication signals to perform sensing functions or using sensing results to assist communication. Sensing functions include target detection, among others.

[0186] In this embodiment, the first sensing signal, the second sensing signal, and / or the third sensing signal are all sensing signals. The sensing signal can be any one of the following: channel state information-reference signal (CSI-RS), synchronization signal block (SSB), positioning reference signal (PRS), sounding reference signal (SRS), sensing reference signal, demodulation reference signal (DMRS), physical random access channel (PRACH), and service request signal (SR). The SRS can be a multi-input multi-output (MIMO) SRS or a positioning SRS, etc.

[0187] For example, in this embodiment, the first sensing resource, the second sensing resource, and / or the third sensing resource are all sensing resources. A sensing resource can be any one of the following: CSI-RS resource, SSB resource, PRS resource, SRS resource, sensing reference signal resource, DMRS resource, PRACH resource (e.g., random access channel occasion, RACH occasion, i.e., RO resource), or SR resource.

[0188] The sensed signal can propagate via the path of "sensing transmitter - sensing target - sensing receiver", or via the path of "sensing transmitter - sensing receiver", or via the path of "sensing transmitter - interference / environment - sensing receiver". In other words, the sensed signal can be a single path or a combination of the above paths, and the sensing receiver receives the sum of the signals from the above paths.

[0189] In this embodiment of the application, the terms "transmitting end", "transmitting end of sensing signal", and "sensing transmitting end" have the same meaning and can be used interchangeably. Similarly, the terms "receiving end", "receiving end of sensing signal", and "sensing receiving end" have the same meaning and can be used interchangeably.

[0190] Therefore, in this embodiment, the transmitted sensing signal can be called sensing signal A, and the received sensing signal can be called sensing signal B. In fact, sensing signal A and sensing signal B are the same signal (e.g., both are referred to as sensing signals). During sensing, changes in sensing signal B compared to sensing signal A include changes caused by reflection or scattering from the sensing target, such as changes in the time and / or frequency domains of the sensing signal, and changes in the amplitude and / or phase of the sensing signal. These changes reflect, to some extent, the information of the sensing target.

[0191] (3) Resource Unit

[0192] Resources include two dimensions: time domain and / or frequency domain. The unit of time domain resources is a time unit, or a time-domain unit. In this embodiment, time unit and time-domain unit have the same meaning and can be used interchangeably. The unit of frequency domain resources is a frequency-domain unit, or a frequency unit. In this embodiment, frequency-domain unit and frequency unit have the same meaning and can be used interchangeably.

[0193] A time unit can be a symbol, an orthogonal frequency division multiplexing (OFDM) symbol, a slot, a sensing slot, a mini-slot, a partial slot, a sub-frame, a frame, or a radio frame. In other words, a time-domain resource can be one or more symbols, OFDM symbols, slots, sensing slots, mini-slots, partial slots, sub-frames, frames, or radio frames.

[0194] Frequency domain units can be resource elements (REs), physical resource blocks (PRBs), resource blocks (RBs), RB sets, channels, subchannels, control channel elements (CCEs), interlacing, combs, resource pools, bandwidth parts (BWPs), bandwidth part groups (BWPGs), carriers, carrier groups, bands, etc. In other words, a frequency domain resource can be one or more resource elements, resource blocks, RB sets, channels, subchannels, control channel elements, interlacing, combs, resource pools, bandwidth parts, bandwidth part groups, carriers, carrier groups, bands, etc.

[0195] The time and frequency units mentioned above can be combined arbitrarily. For example, a resource unit can be a time-frequency resource unit where the time unit is a symbol and the frequency unit is a resource particle. Another example is a time-frequency resource unit where the time unit is a symbol and the frequency unit is a resource block.

[0196] In the embodiments of this application, the time unit for transmitting the sensing signal can also be called the transmission occasion of the sensing signal, and the two can be used interchangeably.

[0197] (4) The positioning principle of Fresnel diffraction

[0198] The Fresnel diffraction positioning principle is based on the target being located on an ellipse or hyperbola with the positions of the transmitting (TX) and receiving (RX) ends of the sensing signal as foci, and the distance the sensing signal travels along the "TX-target-RX" path as its major axis. For example, referring to Figure 1A, taking a point on an ellipse where the target is located, the foci of the ellipse are the positions of TX and RX, and the distance along the major axis of the ellipse is the distance the sensing signal travels along the "TX-target-RX" path.

[0199] As shown in Figure 1A, the distance between TX and RX is D, meaning the distance the sensing signal travels along the "TX-RX" path is D; the distance between TX and the target is d1, and the distance between the target and RX is d2, meaning the distance the sensing signal travels along the "TX-target-RX" path is d1+d2. The sensing signal received by RX includes the sensing signal propagated along the "TX-target-RX" path (e.g., sensing signal 1) and the sensing signal propagated along the "TX-RX" path (e.g., sensing signal 2). The distance difference between sensing signal 1 and sensing signal 2 satisfies the following formula 1:

[0200] in, N represents the number of wavelengths of the subcarriers (hereinafter referred to as subcarriers) used to modulate the sensing signal corresponding to this distance difference, where N is an integer number of cycles, i.e., the integer part of the number of wavelengths of the subcarriers (N is an integer). This is the fractional part of the number of wavelengths of the subcarrier. Let λ be the phase difference between the received phase of sensing signal 1 and the received phase of sensing signal 2, λ be the wavelength of the subcarrier, c be the propagation speed of the sensing signal (i.e., the speed of light), and f be the frequency of the subcarrier.

[0201] in, This indicates the Fresnel region where the target is located. Here, N indicates that the target is located between the Nth Fresnel region and the (N+1)th Fresnel region. This indicates that the target is located at the 2πth part of the interval. The corresponding position.

[0202] It is understandable that sensing signal 1 and sensing signal 2 are sensing signals that are the same sensing signal propagated through different paths. The sensing signals received by the receiving end from these different paths may have certain differences, such as differences in received amplitude and / or received phase. Therefore, for ease of description, they are referred to as sensing signal 1 and sensing signal 2. In fact, the sensing signal received by the receiving end is the sum of sensing signal 1 and sensing signal 2.

[0203] The phase change frequency (or amplitude change frequency) of the sensed signal received by the receiver and this phase difference The frequencies of change are the same. Therefore, the phase difference can be determined based on the phase (or amplitude) of the received sensed signal. Then based on this phase difference Determine the propagation distance d1+d2 of the "TX-target-RX" path. That is, the target is located on an ellipse with the positions of TX and RX as foci and d1+d2 as the major axis.

[0204] As can be seen from Formula 1, when determining D, When λ, c, and f are given, the value of d1+d2 can be determined, thus allowing the construction of an ellipse (ellipse 1) with the positions of TX and RX as foci and d1+d2 as the major axis. Here, D can be determined based on the positions of TX and RX, the wavelength or frequency of the subcarrier used to modulate the sensing signal is a known parameter, and the phase difference can be determined from the phase of the received sensing signal. That is, only the number of cycles N is unknown. Therefore, once the number of cycles N is determined, the ellipse 1 can be constructed.

[0205] Optionally, the sensing signal can be modulated using one or more subcarriers. When the sensing signal is modulated using multiple (e.g., M) subcarriers, the propagation distance difference of the sensing signal corresponding to each subcarrier satisfies Formula 1 above, and the frequencies (or wavelengths) of different subcarriers correspond to different phase differences. Taking the i-th subcarrier among these multiple subcarriers as an example, the propagation distance difference of the sensing signal corresponding to the i-th subcarrier satisfies the following Formula 2. Where 1≤i≤M, and i is an integer.

[0206] in, N represents the number of wavelengths corresponding to this distance difference. i It represents the integer number of cycles of the i-th subcarrier, that is, the integer part of the number of wavelengths of the i-th subcarrier. The fractional part representing the number of wavelengths of the i-th subcarrier. The phase difference of the received phase of the sensing signal modulated using the i-th subcarrier is taken as an example, where the sensing signal received by the receiver on the i-th subcarrier is the sum of sensing signal 1 and sensing signal 2. Let λ be the phase difference between the received phase of sensing signal 1 and the received phase of sensing signal 2. i Let f be the wavelength of the i-th subcarrier, c be the propagation speed of the sensed signal (i.e., the speed of light), and f be the wavelength of the i-th subcarrier. i Let be the frequency of the i-th subcarrier.

[0207] Understandable. This indicates the Fresnel region where the target is located. Where N... i This indicates that the target is located at the Nth position. i Fresnel District and Nth i The interval between +1 Fresnel zones. This indicates that the target is located at the 2πth part of the interval. The corresponding position.

[0208] It is understandable that the subcarrier i (i = 1, 2, ..., M) and subcarrier j (j = 1, 2, ..., M) included in the sensing signal both satisfy Formula 1. That is, the integer number N of subcarrier i... i The integer number N of subcarrier j jThe following formula 3 is satisfied:

[0209] As can be seen from Formula 3, based on the phase difference of multiple subcarriers The integer number N can be determined. i N j Then, the propagation distance d1+d2 of the "TX-target-RX" path is determined.

[0210] In other words, the first device can be based on the frequency of the subcarrier (e.g., f). i (or the wavelength of the subcarrier (e.g., λ)) i )) and phase difference (e.g. Determine the distance d1+d2 of the path propagation from "TX-target-RX". The target is located on an ellipse with the positions of TX and RX as foci and d1+d2 as the major axis.

[0211] Similarly, a hyperbola can be constructed with the positions of RX1 (sensing receiver 1) and RX2 (sensing receiver 2) as foci, and the distance difference of the sensing signal propagating along the paths "TX-target-RX2" and "TX-target-RX1" as the real axis. For example, referring to Figure 1B, the target is located on a hyperbola with the positions of RX1 and RX2 as foci and |d3-d4| as the real axis. In this embodiment, an ellipse is used as an example.

The terminal device can communicate with multiple base stations using different access technologies. The core network equipment is used to implement functions such as mobility management, data processing, session management, policy and accounting. The names of the equipment implementing core network functions may differ in systems using different access technologies; this application does not limit this.Taking the 5th generation (5G) mobile communication technology system as an example, the core network equipment includes, for example, access and mobility management function (AMF), session management function (SMF), policy control function (PCF), or user plane function (UPF), etc.

[0216] 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 RAN (ORAN) system, CU can also be called open CU (open CU, O-CU), DU can also be called open DU (open DU, O-DU), CU-CP can also be called open CU-CP (open CU-CP, O-CU-CP), CU-UP can also be called open CU-UP (open CU-CP, O-CU-UP), and RU can also be called open RU (open RU, O-RU).

[0218] In this application embodiment, the communication device used to implement the network device function can be a network device or a device capable of supporting the network device to implement the function, such as a chip system, which can be installed in the network device. In the technical solutions provided in the embodiments of this application, the technical solutions provided in the embodiments of this application are described with the example of a network device being used to implement the function of a network device (for example, an access network device being used to implement the function of an access network device, or a core network device being used to implement the function of a core network device).

[0219] The preceding text introduced some terms and concepts involved in the embodiments of this application. The following text introduces the technical background involved in the embodiments of this application.

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

[0221] Communication-sensing integration combines wireless communication and sensing functions into a single system. It utilizes the various propagation characteristics of wireless signals to achieve sensing functions such as target localization, detection, imaging, and identification, thereby acquiring information about the surrounding physical environment, improving communication performance, and enhancing user experience. In communication-sensing integration technology, sensing signals are used to obtain information such as the position and velocity of targets in the environment. Taking target position acquisition as an example, please refer to Figure 1A or Figure 1B. Sensing signals can only determine that the target lies on an ellipse or hyperbola, but cannot determine the specific point on the ellipse or hyperbola, resulting in poor positioning accuracy, i.e., poor sensing performance.

[0222] In view of this, embodiments of this application provide a sensing method and apparatus. In this method, a first apparatus can receive different sensing signals (e.g., the first sensing signal and the second sensing signal described below) on different resources, and perceive target information through the two sensing signals, resulting in better sensing performance. Furthermore, receiving the first sensing signal and the second sensing signal on different resources (e.g., sensing resources) helps reduce the probability of conflict between the first sensing signal and the second sensing signal.

[0223] The technical solutions provided in the embodiments of this application can be applied to integrated communication and sensing systems. An integrated communication and sensing system is a system that integrates communication and sensing systems. Sensing can also be understood as detection, such as detecting the position, distance, and angle of a target object. In an integrated communication and sensing system, one or more communication devices can be used as sensing (detection) nodes to form a sensing network. The working principle of sensing is to determine the attribute information (e.g., speed, distance, shape, size, etc.) of the sensed target by sending a signal and receiving the sensing signal (also called the echo signal) reflected by the sensed target. The sensed target can be a fixed object, such as mountains, forests, or buildings, or a movable object, such as a vehicle, drone, human body, or terminal device. The communication device acting as a sensing node is also called a sensing device, sensing apparatus, or detector. Any device with sensing capabilities can be used as a sensing device; for example, a terminal device with sensing capabilities is a type of sensing device.

[0224] This application does not limit the type of communication system in the integrated communication and sensing system. For example, the communication system can be a communication system related to the 3rd Generation Partnership Project (3GPP). For example, the communication system can be LTE, the sixth generation (5G) mobile communication system (e.g., NR communication system), or it can also be applied to other future mobile communication systems, or other similar communication systems. Other similar communication systems may include wireless fidelity (WIFI), vehicle-to-everything (V2X), Internet of Things (IoT) systems, narrowband Internet of Things (NB-IoT) systems, and so on.

[0225] Please refer to Figure 2, which is a schematic diagram of various sensing modes provided in the embodiments of this application. Figure 2 illustrates a vehicle as the sensing target and provides six sensing modes. Among them, the vehicle in Figure 2 is for illustration, and the sensing target can also be other forms. The six sensing modes are: the sensing mode of network device A sending and receiving sensing signals as shown in (1) of Figure 2, that is, network device A sends and receives sensing signals; the sensing mode of terminal device A sending and receiving sensing signals as shown in (2) of Figure 2, that is, terminal device A sends and receives sensing signals; the sensing mode of network device A sending sensing signals and network device B receiving sensing signals as shown in (3) of Figure 2; the sensing mode of terminal device A sending sensing signals and terminal device B receiving sensing signals as shown in (4) of Figure 2; the sensing mode of network device A sending sensing signals and terminal device A receiving sensing signals as shown in (5) of Figure 2; and the mode of terminal device A sending sensing signals and network device A receiving sensing signals as shown in (6) of Figure 2. Figure 2 shows a smartphone as an example of a terminal device.

[0226] For sensing, depending on the different transmitting and receiving ends of the sensing signal, sensing modes can be divided into two types: mono-static sensing and bi-static sensing. In mono-static sensing mode, the transmitting and receiving ends of the sensing signal are located in the same device (e.g., network device or terminal device). For example, the sensing modes shown in Figure 2 (1) or (2).

[0227] In dual-station sensing mode, the transmitting end and the receiving end of the sensing signal are not in the same device. For example, the sensing modes shown in Figure 2 (3), (4), (5) or (6).

[0228] The embodiments of this application can be applied to any of the scenarios shown in Figure 2, or they can also be used in other scenarios, such as any scenario involving sensing services.

[0229] The method provided in the embodiments of this application is described below with reference to the accompanying drawings. In various embodiments of this application, the signal used to implement the sensing function or sensing service is referred to as the sensing signal. The sensing signal is transmitted through reflection, scattering, or diffraction, etc. The sensing device (e.g., the first device) can determine the relevant characteristics of the sensing target based on the received sensing signal, such as estimating time delay, Doppler, or angular spectrum information based on the received sensing signal to determine information such as the distance, angle, or velocity of the sensing target. In addition, the sensing device can also send measurement results to other devices (e.g., sensing network elements, the second, third, fourth, or fifth devices described below), such as sending information such as the distance, angle, or velocity of the sensing target. In the accompanying drawings corresponding to the various embodiments of this application, steps indicated by dashed lines are optional steps.

[0267] Sensing resources can include time-domain resources and / or frequency-domain resources. Specifically, the time-domain resources can be described as time-domain resources of the sensed signal, the starting time-domain unit of the time-domain resources can be described as the starting time-domain unit of the sensed signal, the ending time-domain unit of the time-domain resources can be described as the ending time-domain unit of the sensed signal, and the time-domain pattern of the time-domain resources can be described as the time-domain pattern of the sensed signal. Similarly, the frequency-domain resources can be described as frequency-domain resources of the sensed signal, the starting frequency-domain unit of the frequency-domain resources can be described as the starting frequency-domain unit of the sensed signal, the ending frequency-domain unit of the frequency-domain resources can be described as the ending frequency-domain unit of the sensed signal, the frequency-domain pattern of the frequency-domain resources can be described as the frequency-domain pattern of the sensed signal, the frequency-domain interval of the frequency-domain resources can be described as the frequency-domain interval of the sensed signal, and the number of frequency-domain units of the frequency-domain resources can be described as the number of frequency-domain units of the sensed signal, etc.

[0268] This application provides a sensing method. Please refer to Figure 3, which is a flowchart of the method.

[0269] S301: Receive a first sensing signal on a first sensing resource and a second sensing signal on a second sensing resource.

[0270] Step S301 can be performed by the first device or by a module therein (e.g., a processor, chip, chip system, circuit, etc.). For example, the first device receives a first sensing signal on a first sensing resource and a second sensing signal on a second sensing resource.

[0271] Figure 3 shows an example of a first device receiving a first sensing signal on a first sensing resource and a second sensing signal on a second sensing resource.

[0272] First, we will introduce the relationship between the first and second sensing resources in the time and frequency domains.

[0273] The relationship between the first and second sensory resources in the time domain.

[0274] The first sensing resource includes a first temporal resource; that is, the temporal resource of the first sensing resource is the first temporal resource. This first temporal resource may include one or more time units. When the first temporal resource includes multiple time units, these multiple time units may be continuous or discontinuous.

[0275] Furthermore, the second sensing resource includes a second time-domain resource, that is, the time-domain resource of the second sensing resource is the second time-domain resource. The second time-domain resource may also include one or more time units. When the second time-domain resource includes multiple time units, these multiple time units may be continuous or discontinuous. The embodiments of this application do not limit the number and continuity of time units included in the first time-domain resource and the second time-domain resource.

[0276] The first time-domain resource may overlap with the second time-domain resource, or the interval between the first and second time-domain resources may be less than or equal to a first time interval. It is understood that the interval between the first and second time-domain resources being less than or equal to the first time interval includes both cases where the first and second time-domain resources overlap and cases where they do not overlap. Therefore, to avoid repetition, this embodiment takes the case where the interval between the first and second time-domain resources is less than or equal to the first time interval, and the first and second time-domain resources do not overlap, as an example. The overlap between the first and second time-domain resources can also be understood as incomplete overlap, meaning that some time units of the first time-domain resource may overlap with some time units of the second time-domain resource. The following discussion addresses the relationship between the first and second time-domain resources when they include different numbers of time units.

[0277] The first time-domain resource may overlap with the second time-domain resource, which can be understood as the first time-domain resource for receiving the first sensing signal from the first device overlapping with the second time-domain resource for receiving the second sensing signal. Similarly, the interval between the first time-domain resource and the second time-domain resource is less than or equal to a first time interval, which can be understood as the interval between the first time-domain resource for receiving the first sensing signal from the first device and the second time-domain resource for receiving the second sensing signal from the first device being less than or equal to the first time interval.

[0278] The following discussion addresses the relationship between the first and second time-domain resources when they include different numbers of time units.

[0279] Case 1: The first time-domain resource includes one time unit (e.g., time unit 1), and the second time-domain resource includes one time unit (e.g., time unit 2).

[0280] The overlap between the first time domain resource and the second time domain resource can be the overlap of time unit 1 and time unit 2, that is, time unit 1 and time unit 2 are the same time unit.

[0281] The interval between the first time domain resource and the second time domain resource is less than or equal to the first time interval, or the interval between time unit 1 and time unit 2 is less than or equal to the first time interval.

[0282] Case 2: The first time domain resource includes one time unit (e.g., time unit 1), and the second time domain resource includes multiple time units.

[0283] The overlap between the first time-domain resource and the second time-domain resource can be the overlap between the first time-domain resource and any one of the multiple time-domain resources included in the second time-domain resource.

[0284] The interval between the first time-domain resource and the second time-domain resource being less than or equal to the first time interval can be either the interval between time unit 1 and the first time unit among the multiple time units included in the second time-domain resource, or the interval between time unit 1 and the first time unit, which is less than or equal to the first time interval. For example, if time unit 1 is earlier than the first time unit, the interval between time unit 1 and the first time unit is less than or equal to the first time interval. Alternatively, the interval between time unit 1 and the last time unit among the multiple time units included in the second time-domain resource can also be less than or equal to the first time interval. For example, if time unit 1 is later than the last time unit, the interval between time unit 1 and the last time unit is less than or equal to the first time interval.

[0285] Case 3: The first time domain resource includes multiple time units, and the second time domain resource includes one time unit (e.g., time unit 2).

[0286] The overlap between the first time domain resource and the second time domain resource can be any time unit among the multiple time units included in the first time domain resource overlapping with time unit 2.

[0287] The interval between the first time-domain resource and the second time-domain resource being less than or equal to the first time interval can be either the interval between the first time unit and time unit 2 in a plurality of time units included in the first time-domain resource being less than or equal to the first time interval. For example, if the first time unit is later than time unit 2, the interval between the first time unit and time unit 2 is less than or equal to the first time interval. Alternatively, the interval between the last time unit and time unit 2 in a plurality of time units included in the first time-domain resource being less than or equal to the first time interval can also be either the interval between the last time unit and time unit 2 in a plurality of time units included in the first time-domain resource being less than or equal to the first time interval. For example, if the last time unit is earlier than time unit 2, the interval between the last time unit and time unit 2 is less than or equal to the first time interval.

[0288] Case 4: The first time domain resource includes multiple time units, and the second time domain resource includes multiple time units.

[0289] The overlap between the first time-domain resource and the second time-domain resource can be as follows: any time unit among the multiple time units included in the first time-domain resource overlaps with any time unit among the multiple time units included in the second time-domain resource; or the first time unit of the first time-domain resource overlaps with the first time unit of the second time-domain resource; or the last time unit of the first time-domain resource overlaps with the last time unit of the second time-domain resource; or the first time-domain resource and the second time-domain resource can completely overlap, that is, the number of time units included in the first time-domain resource is the same as the number of time units included in the second time-domain resource, the first time unit of the first time-domain resource overlaps with the first time unit of the second time-domain resource, and the last time unit of the first time-domain resource overlaps with the last time unit of the second time-domain resource.

[0290] The interval between the first time-domain resource and the second time-domain resource being less than or equal to the first time interval can be: the interval between the first time unit of the first time-domain resource and the first time unit of the second time-domain resource is less than or equal to the first time interval; or the interval between the last time unit of the first time-domain resource and the last time unit of the second time-domain resource is less than or equal to the first time interval; or the interval between the last time unit of the first time-domain resource and the first time unit of the second time-domain resource is less than or equal to the first time interval, for example, when the last time unit of the first time-domain resource is earlier than the first time unit of the second time-domain resource, the interval between the last time unit of the first time-domain resource and the first time unit of the second time-domain resource is less than or equal to the first time interval; or the interval between the first time unit of the first time-domain resource and the last time unit of the second time-domain resource is less than or equal to the first time interval, for example, when the first time unit of the first time-domain resource is later than the last time unit of the second time-domain resource, the interval between the first time unit of the first time-domain resource and the last time unit of the second time-domain resource is less than or equal to the first time interval. In the following embodiments, it is taken that both the first and second time-domain resources include multiple time units as an example.

[0291] Optionally, the first time interval may be determined by the first device based on sensing requirements, or it may be indicated by other devices (such as the second or fifth device described below), or it may be determined according to sensing QoS, or it may be predefined by the protocol. The sensing requirements may be, for example, sensing accuracy requirements; the higher the sensing accuracy, the smaller the first time interval, and the lower the sensing accuracy, the larger the first time interval. Alternatively, the sensing requirements may be speed requirements; the faster the speed, the smaller the first time interval, and the slower the speed, the larger the first time interval. The sensing requirements may also be the maximum speed of the sensing target; the faster the maximum speed, the smaller the first time interval, and the slower the maximum speed, the larger the first time interval. The speed requirements may be, for example, the target's movement speed requirements, or the first device's movement speed requirements; this embodiment of the application does not limit this.

[0292] The relationship between the first and second sensing resources in the frequency domain.

[0293] The first sensing resource also includes a first frequency domain resource, that is, the frequency domain resource of the first sensing resource is the first frequency domain resource. The first frequency domain resource may include one or more frequency domain units. When the first frequency domain resource includes multiple frequency domain units, the multiple frequency domain units may be continuous or discontinuous. The embodiments of this application do not limit the number or continuity of the frequency domain units included in the first frequency domain resource.

[0294] For example, the first frequency domain resource may include one or more first frequency domain units, and the mapping of the first sensing signal onto the first sensing resource can be understood as the mapping of the first sensing signal onto the first frequency domain unit of the first sensing resource. The first frequency domain unit may be, for example, a PRB, a RE, or other frequency domain units, and the embodiments of this application do not limit it in this way.

[0295] Furthermore, the second sensing resource includes a second frequency domain resource, that is, the frequency domain resource of the second sensing resource is the second frequency domain resource. The second frequency domain resource may also include one or more frequency domain units. When the second frequency domain resource includes multiple frequency domain units, these multiple frequency domain units may be continuous or discontinuous. This application embodiment does not limit the number and continuity of the frequency domain units included in the second frequency domain resource. In this application embodiment, it is taken as an example that both the first frequency domain resource and the second frequency domain resource include multiple frequency domain units.

[0296] For example, the second frequency domain resource may include one or more second frequency domain units, and the mapping of the second sensing signal onto the second sensing resource can be understood as the mapping of the second sensing signal onto the second frequency domain units of the second sensing resource. The second frequency domain unit may be, for example, a PRB, a RE, or other frequency domain units, and the embodiments of this application do not limit this.

[0297] Optionally, the first frequency domain resource and the second frequency domain resource are orthogonal, that is, the first frequency domain resource and the second frequency domain resource can belong to different frequency domain resource sets; or, the first frequency domain resource and the second frequency domain resource can belong to different frequency domain units in the same frequency domain resource set.

[0298] As one implementation, the first frequency domain resource and the second frequency domain resource belong to different frequency domain resource sets. For example, the first frequency domain resource belongs to the first frequency domain resource set, and the second frequency domain resource belongs to the second frequency domain resource set.

[0299] Optionally, the first frequency domain resource set and the second frequency domain resource set are distributed in a comb pattern. For example, the first frequency domain resource set is the first comb tooth, and the second frequency domain resource set is the second comb tooth, that is, the first frequency domain resources belong to the first comb tooth, and the second frequency domain resources belong to the second comb tooth.

[0300] As an alternative implementation, the first and second frequency domain resources can also belong to different frequency domain units within the same set of frequency domain resources. For example, the first and second frequency domain resources may belong to different frequency domain units within the same set of frequency domain resources.

[0301] Optionally, the third frequency domain resource set is distributed in a comb-like pattern. For example, the third frequency domain resource set is a third comb, meaning that the first and second frequency domain resources belong to different frequency domain units within the third comb.

[0302] The following discussion addresses the relationships satisfied by frequency domain resource sets when the first and second frequency domain resources belong to different frequency domain resource sets, or when the first and second frequency domain resources belong to different frequency domain units of the same frequency domain resource set.

[0303] Case A: The first frequency domain resource belongs to the first frequency domain resource set, and the second frequency domain resource belongs to the second frequency domain resource set. The first frequency domain resource set and the second frequency domain resource set satisfy at least one of the following relationships:

[0304] (1) The minimum frequency domain interval between the frequency domain units included in the first frequency domain resource set and the frequency domain units included in the second frequency domain resource set is greater than or equal to the first frequency domain interval. That is, the frequency domain interval between any frequency domain unit included in the first frequency domain resource set and any frequency domain unit included in the second frequency domain resource set is greater than or equal to the first frequency domain interval. Or, the frequency domain interval between two frequency domain units with the same index in the first and second frequency domain resource sets is greater than or equal to the first frequency domain interval. For example, please refer to Figure 4. The frequency domain interval 1 in Figure 4 is the minimum frequency domain interval between the frequency domain units included in the first and second frequency domain resource sets, and this frequency domain interval 1 is greater than or equal to the first frequency domain interval.

[0305] It is understandable that the first frequency domain spacing is to avoid the mutual interference between the first and second sensing signals.

[0306] (2) The minimum frequency domain interval of the multiple frequency domain units included in the first frequency domain resource set is greater than or equal to the second frequency domain interval. That is, the frequency domain interval between any two frequency domain units included in the first frequency domain resource set is greater than or equal to the second frequency domain interval. The minimum frequency domain interval of the multiple frequency domain units included in the first frequency domain resource set can also be understood as the frequency domain interval between frequency domain units with adjacent indices in the first frequency domain resource set. For example, please refer to Figure 4. The frequency domain interval 2 in Figure 4 is the minimum frequency domain interval of the multiple frequency domain units included in the first frequency domain resource set, and this frequency domain interval 2 is greater than or equal to the second frequency domain interval.

[0307] It is understandable that the second frequency domain spacing is to avoid mutual interference between the first sensing signals on different frequency domain units.

[0308] (3) The minimum frequency domain spacing of the multiple frequency domain units included in the second frequency domain resource set is greater than or equal to the third frequency domain spacing. That is, the frequency domain spacing between any two frequency domain units included in the second frequency domain resource set is greater than or equal to the third frequency domain spacing. The minimum frequency domain spacing of the multiple frequency domain units included in the second frequency domain resource set can also be understood as the frequency domain spacing between frequency domain units with adjacent indices in the second frequency domain resource set. For example, please refer to Figure 4. The frequency domain spacing 3 in Figure 4 is the minimum frequency domain spacing of the multiple frequency domain units included in the second frequency domain resource set, and this frequency domain spacing 3 is greater than or equal to the third frequency domain spacing.

[0309] It is understandable that the third frequency domain spacing is to avoid mutual interference between the second sensing signals on different frequency domain units.

[0310] (4) The minimum frequency domain spacing of the multiple frequency domain units included in the first frequency domain resource set is the same as the minimum frequency domain spacing of the multiple frequency domain units included in the second frequency domain resource set. That is, the frequency domain spacing between indexed adjacent frequency domain units in the first frequency domain resource set is the same as the frequency domain spacing between indexed adjacent frequency domain units in the second frequency domain resource set. For example, please refer to Figure 4, where frequency domain spacing 2 and frequency domain spacing 3 are the same.

[0311] It is understandable that the frequency domain spacing is the same so that the first frequency domain resource set and the second frequency domain resource set do not overlap, that is, to avoid the mutual influence between the first sensing signal and the second sensing signal.

[0312] (5) The total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located is the same as the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located. Alternatively, it can be described as the total number of frequency domain resource sets in the first time unit being the same as the total number of frequency domain resource sets in the second time unit, wherein the frequency domain resource set in the first time unit includes the first frequency domain resource set, and the frequency domain resource set in the second time unit includes the second frequency domain resource set.

[0313] It is understandable that the total number of frequency domain resource sets is the same. In order to determine different first frequency domain resource sets and second frequency domain resource sets among multiple frequency domain resource sets, the first frequency domain resource sets and second frequency domain resource sets are guaranteed not to overlap, that is, to avoid mutual interference between the first sensing signal and the second sensing signal.

[0314] Taking a comb-like distribution of the first and second frequency domain resource sets as an example, the total number of frequency domain resource sets in the first time unit containing the first frequency domain resource set can be understood as the comb index of the first frequency domain resource set (i.e., the first comb tooth). Similarly, the total number of frequency domain resource sets in the second time unit containing the second frequency domain resource set can be understood as the comb index of the second frequency domain resource set (i.e., the second comb tooth). In other words, the total number of frequency domain resource sets in the first time unit containing the first frequency domain resource set is the same as the total number of frequency domain resource sets in the second time unit containing the second frequency domain resource set; this can be understood as the comb index of the first comb tooth being the same as the comb index of the second comb tooth.

[0315] For example, the comb number of the first comb tooth and the comb number of the second comb tooth are both A. Each A consecutive frequency domain units (e.g., PRBs) includes one first frequency domain unit, meaning the minimum frequency domain interval between two first frequency domain units is A. Each A consecutive PRBs includes one second frequency domain unit, meaning the minimum frequency domain interval between two second frequency domain units is also A. For example, A = 4, and further, A = 8.

[0316] (6) The index of the first frequency domain resource set is different from the index of the second frequency domain resource set. Alternatively, it can be understood that the index of the starting frequency domain unit (e.g., the first starting frequency domain unit) of the first frequency domain resource set is different from the index of the starting frequency domain unit (e.g., the second starting frequency domain unit) of the second frequency domain resource set.

[0317] Taking the example where the first and second frequency domain resource sets are distributed like a comb, the index of the frequency domain resource set can be understood as the comb offset. For example, the index of the first frequency domain resource set can be understood as the offset of the first comb tooth, and the index of the second frequency domain resource set can be understood as the offset of the second comb tooth.

[0318] For example, the frequency domain units included in the first and second frequency domain resource sets are PRBs. The index of the first starting frequency domain unit (e.g., the first starting PRB) can be understood as the first starting PRB offset, and the index of the second starting frequency domain unit (e.g., the second starting PRB) can be understood as the second starting PRB offset. Here, the first starting PRB offset is the PRB offset of the first comb tooth, and the second starting PRB offset is the PRB offset of the second comb tooth.

[0319] The index of the first frequency domain resource set is different from that of the second frequency domain resource set. This can be understood as the starting PRB offset of the first comb tooth being different from that of the second comb tooth.

[0320] For example, the frequency domain units included in the first and second frequency domain resource sets are REs. The index of the first starting frequency domain unit (e.g., the first starting RE) can be understood as the first starting RE offset, and the index of the second starting frequency domain unit (e.g., the second starting RE) can be understood as the second starting RE offset. Here, the first starting RE offset is the RE offset of the first comb tooth, and the second starting RE offset is the RE offset of the second comb tooth.

[0321] The index of the first frequency domain resource set is different from the index of the second frequency domain resource set. This can be understood as the starting RE offset of the first comb tooth being different from the starting RE offset of the second comb tooth.

[0322] Optionally, the index of the first frequency domain resource set can be determined based on the index of the second frequency domain resource set and / or the total number of frequency domain resource sets in the second time unit where the second frequency domain resource set is located (e.g., the comb number of the second comb tooth); or, the index of the second frequency domain resource set can be determined based on the index of the first frequency domain resource set and / or the total number of frequency domain resource sets in the first time unit where the first frequency domain resource set is located (e.g., the comb number of the first comb tooth).

[0323] It is understandable that relation (6) can be understood as the offset of the first comb tooth can be determined based on the offset of the second comb tooth and / or the comb number of the second comb tooth; or, the offset of the second comb tooth can be determined based on the offset of the first comb tooth and / or the comb number of the first comb tooth.

[0324] As an example, the difference between the offset of the first comb tooth (e.g., B1) and the offset of the second comb tooth (e.g., B2) is a first value. This first value can be related to the comb number of the first comb tooth (e.g., A1), or it can be related to the comb number of the second comb tooth (e.g., A2). Taking the first value being related to the comb number of the first comb tooth as an example.

[0325] For example, the first value is A1 / 2, that is, B1-B2 = A1 / 2 or B1-B2 = -A1 / 2.

[0326] For example, the first value is Right now or

[0327] For example, the first value is Right now or

[0328] As another example, the difference between the offset of the first comb tooth (e.g., B1) and the offset of the second comb tooth (e.g., B2) is greater than or equal to a second value. For example, this second value could be F, i.e., B1-B2≥F or B2-B1≥F.

[0329] As another example, the difference between the offset of the first comb tooth (e.g., B1) and the offset of the second comb tooth (e.g., B2) is less than or equal to a third value. For example, this third value could be G, i.e., B1-B2≤F or B2-B1≤F.

[0330] As another example, the offset of the first comb tooth (e.g., B1) is equal to the offset of the second comb tooth (e.g., B2). For example, the RE offset of the first comb tooth is equal to the RE offset of the second comb tooth.

[0331] In the above example, the offset of the first comb tooth can be either the PRB offset (first starting PRB offset) or the RE offset (first starting RE offset). Similarly, the offset of the second comb tooth can be either the PRB offset (second starting PRB offset) or the RE offset (second starting RE offset).

[0332] (7) The number of frequency domain units included in the first frequency domain resource set is the same as the number of frequency domain units included in the second frequency domain resource set.

[0333] For example, the number of first frequency domain units D1 included in the first comb tooth is the same as the number of second frequency domain units D2 included in the second comb tooth. That is, D1 = D2. The number of frequency domain units can be either the number of PRBs or the number of REs.

[0334] Case B: The first frequency domain resource and the second frequency domain resource belong to different frequency domain units in the third frequency domain resource set, and the multiple frequency domain units in the third frequency domain resource set satisfy at least one of the following relationships.

[0335] (1) The minimum frequency domain spacing of multiple frequency domain units in the third frequency domain resource set is greater than or equal to the fourth frequency domain spacing. That is, in the third frequency domain resource set, the frequency domain spacing between any frequency domain unit mapping the first sensing signal and any frequency domain unit mapping the second sensing signal is greater than or equal to the fourth frequency domain spacing. The minimum frequency domain spacing of multiple frequency domain units included in the third frequency domain resource set can also be understood as the frequency domain spacing between frequency domain units with adjacent indices in the third frequency domain resource set.

[0336] It is understandable that the fourth frequency domain spacing is to avoid the mutual interference between the first and second sensing signals.

[0337] (2) The minimum frequency domain spacing of multiple frequency domain units of the first frequency domain resource in the third frequency domain resource set is the same as the minimum frequency domain spacing of multiple frequency domain units of the second frequency domain resource in the third frequency domain resource set. That is, in the third frequency domain resource set, the minimum frequency domain spacing of two frequency domain units mapping the first sensing signal is the same as the minimum frequency domain spacing of two frequency domain units mapping the second sensing signal. Or, in the third frequency domain resource set, the spacing of two adjacent frequency domain units mapping the first sensing signal is the same as the spacing of two adjacent frequency domain units mapping the second sensing signal.

[0338] It is understandable that the minimum frequency domain spacing of multiple frequency domain units of the first frequency domain resource in the third frequency domain resource set is the same as the minimum frequency domain spacing of multiple frequency domain units of the second frequency domain resource in the third frequency domain resource set in order to ensure that the first frequency domain resource and the second frequency domain resource do not overlap, that is, to avoid mutual interference between the first sensing signal and the second sensing signal.

[0339] Optionally, the third frequency domain resource set includes a first sub-frequency domain resource set and a second sub-frequency domain resource set, wherein the first frequency domain resources belong to the first sub-frequency domain resource set and the second frequency domain resources belong to the second sub-frequency domain resource set.

[0340] For example, the third frequency domain resource set includes the first sub-frequency domain resource set corresponding to the first frequency domain resource and the second sub-frequency domain resource set corresponding to the second frequency domain resource. The minimum frequency domain spacing of multiple frequency domain units of the first frequency domain resource in the third frequency domain resource set can also be understood as the frequency domain spacing between indexed adjacent frequency domain units in the first sub-frequency domain resource set, and the minimum frequency domain spacing of multiple frequency domain units of the second frequency domain resource can also be understood as the frequency domain spacing between indexed adjacent frequency domain units in the second sub-frequency domain resource set.

[0341] Optionally, the first sub-frequency domain resource set and the second sub-frequency domain resource set satisfy at least one of the following relationships:

[0342] (2A) The minimum frequency domain spacing of the multiple frequency domain units included in the first sub-frequency domain resource set is greater than or equal to the frequency domain spacing A. That is, the frequency domain spacing between any two frequency domain units included in the first sub-frequency domain resource set is greater than or equal to the frequency domain spacing A. The minimum frequency domain spacing of the multiple frequency domain units included in the first sub-frequency domain resource set can also be understood as the frequency domain spacing between frequency domain units with adjacent indices in the first sub-frequency domain resource set.

[0343] It is understandable that the frequency domain spacing A is to avoid mutual interference between the first sensing signals on different frequency domain units.

[0344] (2B) The minimum frequency domain spacing of the multiple frequency domain units included in the second sub-frequency domain resource set is greater than or equal to the frequency domain spacing B. That is, the frequency domain spacing between any two frequency domain units included in the second sub-frequency domain resource set is greater than or equal to the frequency domain spacing B. The minimum frequency domain spacing of the multiple frequency domain units included in the second sub-frequency domain resource set can also be understood as the frequency domain spacing between frequency domain units with adjacent indices in the second sub-frequency domain resource set.

[0345] It is understandable that the frequency domain spacing B is to avoid mutual interference between the second sensing signals on different frequency domain units.

[0346] (3) The index of the sub-frequency domain resource set corresponding to the first frequency domain resource in the third frequency domain resource set (e.g., the first sub-frequency domain resource set) is different from the index of the sub-frequency domain resource set corresponding to the second frequency domain resource (e.g., the second sub-frequency domain resource set). The index of the first sub-frequency domain resource set can also be understood as the index of the starting frequency domain unit of the first sub-frequency domain resource set, and the index of the second sub-frequency domain resource set can also be understood as the index of the starting frequency domain unit of the second sub-frequency domain resource set.

[0347] As an example, the third frequency domain resource set includes N1 frequency domain cells, where N1 is an integer greater than 1. The first frequency domain resource consists of the frequency domain cells with index x satisfying x mod M1 = i among the N1 frequency domain cells. The second frequency domain resource consists of the frequency domain cells with index x satisfying x mod M1 = j among the N1 frequency domain cells. M1 is an integer greater than 1 and less than N1, and i and j are integers greater than or equal to 0 and less than M1, i ≠ j. That is, the first sub-frequency domain resource set includes the frequency domain cells with index x satisfying x mod M1 = i among the N1 frequency domain cells, and the second sub-frequency domain resource set includes the frequency domain cells with index x satisfying x mod M1 = j among the N1 frequency domain cells.

[0348] "Mod" is an abbreviation for modulo operation, used to calculate the remainder after dividing two numbers. The modulo operation is usually expressed as a mod b, where a is the dividend, b is the divisor, and the result is the remainder after dividing a by b.

[0349] Where M1 can be any one of {1,2,3,4,5,6,7,8,9,10}. Alternatively, M1 can be the number of sensing signals carried by the third frequency domain resource set. Taking the example that each sensing signal corresponds to one sub-frequency domain resource set, M1 is the number of sub-frequency domain resource sets included in the third frequency domain resource set. For example, if the third frequency domain resource set only carries the first and second sensing signals, then M1 = 2.

[0350] Optionally, the first sub-frequency domain resource set includes frequency domain units with odd index numbers among the N1 frequency domain units, and the second sub-frequency domain resource set includes frequency domain units with even index numbers among the N1 frequency domain units, i.e., i = 1, j = 0. For example, please refer to Figure 5(a), where Figure 5(a) takes frequency domain unit RE and N1 = 24 as an example.

[0351] Alternatively, the first sub-frequency domain resource set includes frequency domain units with even index numbers among the N1 frequency domain units, and the second sub-frequency domain resource set includes frequency domain units with odd index numbers among the N1 frequency domain units, i.e., i = 0, j = 1.

[0352] As another example, the third frequency domain resource set includes N1 frequency domain units, where N1 is an integer greater than 1. The first frequency domain resource consists of frequency domain units with index x satisfying x mod M1 = i, and the second frequency domain resource consists of frequency domain units with index x satisfying x mod M1 = j. M1 is an integer greater than 1 and less than N1, and i and j are integers greater than or equal to 0 and less than M1, where i ≠ j. That is, the first sub-frequency domain resource set includes frequency domain units with index x satisfying x mod M1 = i, and the second sub-frequency domain resource set includes frequency domain units with index x satisfying x mod M1 = j. The descriptions of M1 and mod can be found in the descriptions of M1 and mod above, and will not be repeated here.

[0353] As another example, the third frequency domain resource set includes N1 frequency domain units, where N1 is an integer greater than 1. The first frequency domain resource is the frequency domain unit with index x of a·N1 / M1~((a+1)·N1 / M1)-1 among the N1 frequency domain units. The second frequency domain resource is the frequency domain unit with index x of b·N1 / M1~((b+1)·N1 / M1)-1 among the N1 frequency domain units. M1 is an integer greater than 1 and less than N1. a and b are integers greater than or equal to 0 and less than M1, and a≠b. That is, the first sub-frequency domain resource set includes frequency domain units with index numbers x of a·N1 / M1 to ((a+1)·N1 / M1)-1 among the N1 frequency domain units, and the second sub-frequency domain resource set includes frequency domain units with index numbers x of b·N1 / M1 to ((b+1)·N1 / M1)-1 among the N1 frequency domain units. The description of M1 can be found above and will not be repeated here.

[0354] In this context, "·" is an abbreviation for multiplication, for example, a·N1 means a multiplied by N1; " / " is an abbreviation for division, for example, N1 / M1 means N1 divided by M1, where N1 is the dividend and M1 is the divisor.

[0355] Taking M1=2 as an example, the first sub-frequency domain resource set includes frequency domain units with index numbers 0 to (N1 / 2)-1 among the N1 frequency domain units, and the second sub-frequency domain resource set includes frequency domain units with index numbers N1 / 2 to N1-1 among the N1 frequency domain units, that is, a=0, b=1. For example, please refer to Figure 5(b), which takes frequency domain unit RE and N1=24 as an example; or, the first sub-frequency domain resource set includes frequency domain units with index numbers N1 / 2 to N1-1 among the N1 frequency domain units, and the second sub-frequency domain resource set includes frequency domain units with index numbers N1 / 2 to N1-1 among the N1 frequency domain units, that is, a=1, b=0.

[0356] As another example, the third frequency domain resource set includes N1 frequency domain units, where N1 is an integer greater than 1. The first frequency domain resource consists of frequency domain units with index x of a·N1 / M1 to ((a+1)·N1 / M1)-1, and the second frequency domain resource consists of frequency domain units with index x of b·N1 / M1 to ((b+1)·N1 / M1)-1. M1 is an integer greater than 1 and less than N1, and a and b are integers greater than or equal to 0 and less than M1, where a≠b. That is, the first sub-frequency domain resource set includes frequency domain units with index x of a·N1 / M1 to ((a+1)·N1 / M1)-1, and the second sub-frequency domain resource set includes frequency domain units with index x of b·N1 / M1 to ((b+1)·N1 / M1)-1. The descriptions of M1, "·", and " / " can be found in the descriptions of M1, "·", and " / " above, and will not be repeated here.

[0357] As another example, the third frequency domain resource set includes P1 physical resource blocks, where P1 is an integer greater than 1. The first frequency domain resource is the physical resource block with index y satisfying y mod M1 = i among the P1 physical resource blocks. The second frequency domain resource is the physical resource block with index y satisfying y mod M1 = j among the P1 physical resource blocks, where M1 is an integer greater than 1, and i and j are integers greater than or equal to 0 and less than P1, i ≠ j. That is, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index y satisfying y mod M1 = i among the P1 physical resource blocks, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index y satisfying y mod M1 = j among the P1 physical resource blocks. The descriptions of M1 and mod can be found in the descriptions of M1 and mod above, and will not be repeated here.

[0358] Taking M1=2 as an example, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with odd index numbers among the P1 physical resource blocks, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with even index numbers among the P1 physical resource blocks, i.e., i=1, j=0. For example, please refer to Figure 5(c). Figure 5(c) takes the frequency domain unit as RE, N1=24, and each physical resource block includes 6 frequency domain units, i.e., P1=4, as an example. In Figure 5, #i is the index number of the physical resource block; or, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with even index numbers among the P1 physical resource blocks, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with odd index numbers among the P1 physical resource blocks, i.e., i=0, j=1.

[0359] As another example, the third frequency domain resource set includes P1 physical resource blocks, where P1 is an integer greater than 1. The first frequency domain resource is the physical resource block with index y satisfying y mod M1 = i, and the second frequency domain resource is the physical resource block with index y satisfying y mod M1 = j, where M1 is an integer greater than 1, and i and j are integers greater than or equal to 0 and less than P1, i ≠ j. That is, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource block with index y satisfying y mod M1 = i, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource block with index y satisfying y mod M1 = j. The description of M1 can be referred to the above description, and will not be repeated here. The descriptions of M1 and mod can be referred to the above descriptions of M1 and mod, and will not be repeated here.

[0360] As another example, the third frequency domain resource set includes P1 physical resource blocks, where P1 is an integer greater than 1. The first frequency domain resource is the physical resource block with index y of a·P1 / M1~((a+1)·P1 / M1)-1 among the P1 physical resource blocks. The second frequency domain resource is the physical resource block with index y of b·P1 / M1~((b+1)·P1 / M1)-1 among the P1 physical resource blocks. M1 is an integer greater than 1 and less than P1. a and b are integers greater than or equal to 0 and less than M1, and a≠b. That is, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index numbers y of a·P1 / M1 to ((a+1)·P1 / M1)-1 among the P1 physical resource blocks, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index numbers y of b·P1 / M1 to ((b+1)·P1 / M1)-1 among the P1 physical resource blocks. The descriptions of M1, "·", and " / " can be found in the descriptions of M1, "·", and " / " above, and will not be repeated here.

[0361] Taking M1=2 as an example, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index numbers 0 to (N1 / 2)-1 in the P1 physical resource blocks, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index numbers N1 / 2 to N1-1 in the P1 physical resource blocks, that is, a=1, b=0. For example, please refer to (d) in Figure 5. Figure 5 (d) takes the frequency domain unit as RE, N1=24, and each physical resource block includes 6 frequency domain units, that is, P1=4. Alternatively, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index numbers N1 / 2 to N1-1 in the P1 physical resource blocks, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource blocks with index numbers 0 to (N1 / 2)-1 in the P1 physical resource blocks, that is, a=0, b=1.

[0362] As another example, the third frequency domain resource set includes P1 physical resource blocks, where P1 is an integer greater than 1. The first frequency domain resource is the physical resource block with index y of a·P1 / M1~((a+1)·P1 / M1)-1, and the second frequency domain resource is the physical resource block with index y of b·P1 / M1~((b+1)·P1 / M1)-1. M1 is an integer greater than 1 and less than P1, and a and b are integers greater than or equal to 0 and less than M1, where a≠b. That is, the frequency domain units included in the first sub-frequency domain resource set are the frequency domain units included in the physical resource block with index y of a·P1 / M1~((a+1)·P1 / M1)-1, and the frequency domain units included in the second sub-frequency domain resource set are the frequency domain units included in the physical resource block with index y of b·P1 / M1~((b+1)·P1 / M1)-1. The description of M1 can be found in the above description and will not be repeated here. Similarly, the descriptions of M1, "·", and " / " can be found in the above descriptions of M1, "·", and " / " and will not be repeated here.

[0363] (4) The number of frequency domain units of the first frequency domain resource in the third frequency domain resource set (e.g., the number of frequency domain units included in the first sub-frequency domain resource set) is the same as the number of frequency domain units of the second frequency domain resource (e.g., the number of frequency domain units included in the second sub-frequency domain resource set).

[0364] The number of frequency domain units can be either the number of PRBs or the number of REs. For example, in the third frequency domain resource set, the number of PRBs in the first frequency domain resource is the same as the number of PRBs in the second frequency domain resource. Similarly, in the third frequency domain resource set, the number of REs in the first frequency domain resource is the same as the number of REs in the second frequency domain resource.

[0365] As mentioned above, the first time-domain resource overlaps with the second time-domain resource, or the interval between the first time-domain resource and the second time-domain resource is less than or equal to the first time interval; and the first frequency-domain resource and the second frequency-domain resource belong to different frequency-domain resource sets, or the first frequency-domain resource and the second frequency-domain resource belong to different frequency-domain units of the same frequency-domain resource set. Based on the above description, the following introduces the possible relationships that the first sensing resource and the second sensing resource can satisfy. The first sensing resource and the second sensing resource can satisfy any of the following relationships:

[0366] Relationship 1: The first time-domain resource overlaps with the second time-domain resource, and the first frequency-domain resource and the second frequency-domain resource belong to different frequency-domain resource sets. That is, the first frequency-domain resource belongs to the first frequency-domain resource set, and the second frequency-domain resource belongs to the second frequency-domain resource set.

[0367] Relationship 2: The first time-domain resource overlaps with the second time-domain resource, and the first frequency-domain resource and the second frequency-domain resource belong to different frequency-domain units of the same frequency-domain resource set. That is, the first frequency-domain resource and the second frequency-domain resource belong to different frequency-domain units in the third frequency-domain resource set.

[0368] Relationship 3: The interval between the first time-domain resource and the second time-domain resource is less than or equal to the first time interval, and the first frequency-domain resource and the second frequency-domain resource belong to different frequency-domain resource sets. That is, the first frequency-domain resource belongs to the first frequency-domain resource set, and the second frequency-domain resource belongs to the second frequency-domain resource set.

[0369] Relationship 4: The interval between the first time domain resource and the second time domain resource is less than or equal to the first time interval, and the first frequency domain resource and the second frequency domain resource belong to different frequency domain units of the same frequency domain resource set, that is, the first frequency domain resource and the second frequency domain resource belong to different frequency domain units in the third frequency domain resource set.

[0370] In any of the above relationships, the first frequency domain resource set is, for example, the first comb tooth, the second frequency domain resource set is, for example, the second comb tooth, and the third frequency domain resource set is, for example, the third comb tooth.

[0371] For example, please refer to Figure 6, which shows an example of the four relationships mentioned above. In Figure 6, the first sensing signal is CSI-RS, the resource mapped to CSI-RS is the first sensing resource, and the second sensing signal is SRS, the resource mapped to SRS is the second sensing resource. In Figure 6, (a) is an example of relationship 1, (b) is an example of relationship 2, (c) is an example of relationship 3, and (d) is an example of relationship 4.

[0372] Optionally, the first sensing resource and the second sensing resource can also be configured. For example, the first sensing resource and the second sensing resource can be configured before executing S301.

[0373] For example, the first and second sensing resources can be configured via a fifth device. This fifth device can be, for example, the first device, or it can be the second, third, or fourth device described below, or it can be any other device; this application embodiment does not limit this. In this application embodiment, the fifth device is taken as an example where it is not any of the first, second, third, or fourth devices.

[0374] Optionally, the method for configuring the first sensing resource and the second sensing resource may be: the fifth device sends first configuration information to the first device and the second device, the first configuration information being used to configure the first sensing resource and the second sensing resource; or, the fifth device sends the first configuration information to the first device and sends second configuration information to the second device, the first configuration information being used to configure the first sensing resource and the second sensing resource, and the second configuration information being used to configure the first sensing resource.

[0375] Optionally, the method shown in Figure 3 may further include S301a and / or S301b:

[0376] S301a: Send a second sensing signal on the second sensing resource.

[0377] Step S301a may be performed by the first device or by a module therein (e.g., processor, chip, chip system, circuit, etc.). Alternatively, step S301a may be performed by the second device or by a module therein (e.g., processor, chip, chip system, circuit, etc.).

[0378] S301b: Send a first sensing signal on the first sensing resource.

[0379] Step S301b can be performed by the first device or by a module therein (e.g., processor, chip, chip system, circuit, etc.). Alternatively, step S301b can be performed by the second device or by a module therein (e.g., processor, chip, chip system, circuit, etc.).

[0380] S301a and / or S301b may be executed before S301, or S301a and / or S301b may be executed simultaneously with S301. This application embodiment does not limit the execution order of S301a and / or S301b with S301.

[0381] In this embodiment, the first sensing signal and the second sensing signal may be sent by the same device. As one example, both the first sensing signal and the second sensing signal may be sent by a first device. As another example, both the first sensing signal and the second sensing signal may be sent by other devices. For instance, both the first sensing signal and the second sensing signal may be sent by a second device.

[0382] Alternatively, the first sensing signal and the second sensing signal may be transmitted by different devices. As one example, the first sensing signal may be transmitted by another device, and the second sensing signal may be transmitted by the first device. For example, the first sensing signal may be transmitted by the second device, and the second sensing signal may be transmitted by the first device. As another example, both the first and second sensing signals may be transmitted by other devices, and the devices transmitting the first and second sensing signals are different. For example, the first sensing signal may be transmitted by the second device, and the second sensing signal may be transmitted by a third device.

[0383] This application does not limit the apparatus for transmitting the first sensing signal and the second sensing signal. In this application, an example is taken where the first sensing signal is transmitted by the second apparatus and the second sensing signal is transmitted by the first apparatus. For example, the first apparatus transmits the second sensing signal on the second sensing resource, and the second apparatus transmits the first sensing signal on the first sensing resource.

[0384] Figure 3 illustrates an example where the first device sends a second sensing signal on the second sensing resource, and the second device sends a first sensing signal on the first sensing resource.

[0385] In the embodiments of this application, the first device and the second device can be different devices, such as the first device being a terminal device and the second device being a network device; or, the first device and the second device can also be different devices within the same device, such as the first device and the second device being different modules (e.g., processor, chip, chip system, circuit, etc.) within the terminal device. The embodiments of this application do not limit this.

[0386] In this embodiment of the application, the first device and the second device are different devices. For example, in this embodiment of the application, the first device is a terminal device and the second device is a network device.

[0387] The first sensing signal can be, for example, CSI-RS, or other forms of sensing signal. The second sensing signal can be, for example, SRS, or other forms of sensing signal.

[0388] The transmitting end of the sensing signal (e.g., a sensing transmitter) can be any one of the following: a transmitting port, a transmitting radio frequency channel, a transmitting radio frequency integrated circuit, a transmitting baseband channel, a transmitting antenna, a transmitting antenna element, a transmitting antenna array element, a transmitting remote radio frequency unit, or a transmitting wireless unit of the device transmitting the sensing signal. For example, the transmitting end of the first sensing signal can be any one of the following: a transmitting port, a transmitting radio frequency channel, a transmitting radio frequency integrated circuit, a transmitting baseband channel, a transmitting antenna, a transmitting antenna element, a transmitting antenna array element, a transmitting remote radio frequency unit, or a transmitting wireless unit of the second device. Similarly, the transmitting end of the second sensing signal can be any one of the following: a transmitting port, a transmitting radio frequency channel, a transmitting radio frequency integrated circuit, a transmitting baseband channel, a transmitting antenna, a transmitting antenna element, a transmitting antenna array element, a transmitting remote radio frequency unit, or a transmitting wireless unit of the first device.

[0389] In this process, the second device sends a first sensing signal on the first sensing resource, and the first device receives the first sensing signal on the first sensing resource. That is, the sending end and the receiving end of the first sensing signal are not in the same device. That is, the sensing mode corresponding to the first sensing signal is a dual-station sensing mode. For example, the sensing mode corresponding to the first sensing signal is the sensing mode shown in (3), (4), (5) or (6) in Figure 2. That is, the first sensing signal is a sensing signal sent by A and received by B.

[0390] The first device sends a second sensing signal on the second sensing resource and receives the second sensing signal on the second sensing resource. That is, the sending end and receiving end of the second sensing signal are in the same device. That is, the sensing mode corresponding to the second sensing signal is a single-station sensing mode. For example, the sensing mode corresponding to the second sensing signal is the sensing mode shown in (1) or (2) in Figure 2. That is, the second sensing signal is a self-sent and self-received sensing signal.

[0391] It can be understood that the sensing signal transmitted by A and received by B (i.e., the first sensing signal) and the self-transmitted and self-received sensing signal (i.e., the second sensing signal) can satisfy any one of the above conditions 1 to 4 in the time domain. Furthermore, the sensing signal transmitted by A and received by B (i.e., the first sensing signal) and the self-transmitted and self-received sensing signal (i.e., the second sensing signal) can satisfy any one of the above conditions A and B in the frequency domain.

[0392] The first and second sensing signals are used to sense target information. This target information may include, for example, at least one of the following: the existence of the target, the target's location information, the distance between the target and the first device, the target's direction information, the target's speed information, the target's acceleration information, the target's direction of motion information, or the target's motion state information. The target's speed information, acceleration information, and direction information can be obtained from changes in the distance between the target and the first device. Optionally, if the target is a living being, such as a person or animal, the target information may also include the target's respiratory rate, heart rate, etc.

[0393] It is understood that the first sensing signal and the second sensing signal are used together to sense target information, or in other words, the target sensed by the first sensing signal and the second sensing signal is the same. In this embodiment of the application, the target information is taken as the target's location information, that is, the target is located using the sensing signal.

[0394] In this embodiment, perceiving target information can also be referred to as determining target information, running a perception service, or simply as performing perception; these terms can be used interchangeably. Specifically, performing perception may include determining at least one of the following: target motion information, target motion change information, target position information, target distance information, target speed information, and target angle information. That is, determining target information can be replaced by determining at least one of motion information, motion change information, position information, distance information, speed information, and angle information.

[0395] For example, after a sensing signal is transmitted from the transmitting end, it may reach the receiving end (e.g., the first device) after being reflected, diffracted, or scattered by one or more targets in physical space. The receiving end can determine the target information based on the characteristics of the received sensing signal. For example, the characteristics of the sensing signal after reflection, diffraction, or scattering by the target are different from the characteristics of the sensing signal transmitted from the transmitting end. The change in the characteristics of the sensing signal received by the receiving end relative to the characteristics of the sensing signal transmitted by the transmitting end can reflect the target information. It can be understood that the receiving end determines the target information based on the change in the characteristics of the sensing signal from the transmitting end to the receiving end; therefore, it can also be said that the transmitted sensing signal (e.g., the first sensing signal, the second sensing signal, and the third sensing signal described below) is used to sense target information.

[0396] Optionally, the target information can be determined based on the received information of the sensing signal. This received information may include, for example, at least one of the following: signal amplitude information, signal phase information, in-phase (I) path information, and quadrature-phase (Q) path information. For instance, the target information is calculated based on at least one of the aforementioned received information; that is, the target information is the result of a calculation based on at least one of the aforementioned signal amplitude information, signal phase information, in-phase path information, and quadrature-phase path information. For example, if the target information is the target's position information and the received information is the received phase, the target information can be determined according to Formula 1 based on the received information of the sensing signal.

[0397] Optionally, the target information can also be a sensing measurement result obtained by measuring the sensing signal. For example, the sensing measurement result can be at least one of the following: time delay information, Doppler information, angle information, signal strength information, etc. In this embodiment, the target information is determined based on the received information of the sensing signal as an example.

[0398] In this embodiment of the application, the first device may include one or more sensing receivers, through which the first device can receive the first sensing signal and the second sensing signal. The sensing receiver may be, for example, any one of a receiving port, a receiving radio frequency channel, a receiving radio frequency integrated circuit, a receiving baseband channel, a receiving antenna, a receiving antenna vibrator, a receiving antenna array element, a receiving remote radio frequency unit, or a receiving wireless unit.

[0399] In one implementation, the first device includes a first sensing receiver. Specifically, the first sensing receiver receives a first sensing signal on a first sensing resource, and the first sensing receiver also receives a second sensing signal on a second sensing resource. The descriptions of the first sensing resource, the second sensing resource, the first sensing signal, and the second sensing signal are given above and will not be repeated here.

[0400] For example, referring to Figure 7A, the first device includes a first sensing receiver. Figure 7A is an example of a target information determined by the first device through receiving a first sensing signal and a second sensing signal at the first sensing receiver. In Figure 7A, TX1 is the transmitting end of the first sensing signal in the second device (e.g., the second sensing transmitting end), TX2 is the transmitting end of the second sensing signal in the first device (e.g., the first sensing transmitting end), and RX1 is the first sensing receiver of the first device; in Figure 7A, ellipse 1 is determined based on the first sensing signal, ellipse 2 is determined based on the second sensing signal, and the target is located at the intersection of ellipse 1 and ellipse 2.

[0401] In other words, the target information can be determined by the first and second sensing signals. As shown in Formulas 1 and 2, in addition to the received information of the sensing signals, constructing an ellipse also requires information such as the position of the transmitting end of the sensing signals, the position of the receiving end of the sensing signals, and the wavelength or subcarrier frequency of the sensing signals.

[0402] For example, ellipse 1 is determined based on the position of the second sensing transmitter, the first sensing signal, and the position of the first sensing receiver. Ellipse 1 is an ellipse with the positions of the first sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 1 is determined based on the position of the second sensing transmitter, the phase (e.g., the first receiving phase) of the first sensing signal received by the first sensing receiver, the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the first sensing signal.

[0403] For example, ellipse 2 is determined based on the position of the first sensing transmitter, the second sensing signal, and the position of the first sensing receiver. Ellipse 2 is an ellipse with the positions of the first sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 2 is determined based on the position of the first sensing transmitter, the phase of the second sensing signal received by the first sensing receiver (e.g., the second receiving phase), the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0404] The intersection of ellipse 1 and ellipse 2 is the location of the target.

[0405] In another implementation, the first device includes a first sensing receiver and a second sensing receiver. The first device can receive the first sensing signal and the second sensing signal through the first sensing receiver and the second sensing receiver. For example, the first sensing receiver of the first device receives the first sensing signal on the first sensing resource, and the second sensing receiver of the first device receives the second sensing signal on the second sensing resource.

[0406] Optionally, the straight line connecting the first sensing receiver and the first sensing transmitter is perpendicular to the straight line connecting the second sensing receiver and the first sensing transmitter. Based on this design, the major axes of ellipse 2 and ellipse 3 are perpendicular. The position of the sensing target can be determined based on the information from ellipse 2 and ellipse 3.

[0407] For example, referring to Figure 7B, the first device includes a first sensing receiver and a second sensing receiver. Figure 7B is an example of a target information determined by the first device through receiving a first sensing signal via the first sensing receiver and a second sensing signal via the second sensing receiver. In Figure 7B, TX1 is the transmitter of the first sensing signal (e.g., the second sensing transmitter), TX2 is the transmitter of the second sensing signal (e.g., the first sensing transmitter), RX1 is the first sensing receiver, and RX2 is the second sensing receiver; in Figure 7B, ellipse 1 is determined based on the first sensing signal, ellipse 3 is determined based on the second sensing signal, and the target is located at the intersection of ellipse 1 and ellipse 3.

[0408] For example, ellipse 1 is determined based on the position of the second sensing transmitter, the first sensing signal, and the position of the first sensing receiver. Ellipse 1 is an ellipse with the positions of the first sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 1 is determined based on the position of the second sensing transmitter, the first receiving phase, the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the first sensing signal.

[0409] For example, ellipse 3 is determined based on the position of the first sensing transmitter, the position of the second sensing signal, and the position of the second sensing receiver. Ellipse 3 is an ellipse with the positions of the second sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 3 is determined based on the position of the first sensing transmitter, the second receiving phase, the position of the second sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0410] The intersection of ellipse 1 and ellipse 3 is the location of the target.

[0411] As shown in Figures 7A and 7B, the target position determined based on two sensing signals includes two locations (e.g., the two intersection points shown in Figures 7A and 7B). Therefore, to further determine the target position, such as which of the two intersection points the target is located at, at least one more ellipse can be constructed based on at least one sensing signal (i.e., three ellipses are needed). The target information (e.g., the target position) is determined based on the intersection point of this at least one ellipse with the two ellipses shown in Figure 7A or 7B. In this embodiment, constructing another ellipse is taken as an example.

[0412] For example, target information can be determined based on the intersection of ellipse 1, ellipse 2, and ellipse 3.

[0413] For example: Ellipse 1, ellipse 2, and ellipse 3 are determined based on the sensing signals received by the first device.

[0414] The descriptions of Ellipse 1, Ellipse 1 and Ellipse 3 can be found in Figures 7A and 7B, and will not be repeated here.

[0415] For example, ellipse 1 is determined based on the position of the second sensing transmitter, the first sensing signal, and the position of the first sensing receiver. Ellipse 1 is an ellipse with the positions of the first sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 1 is determined based on the position of the second sensing transmitter, the phase (e.g., the first receiving phase) of the first sensing signal received by the first sensing receiver, the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the first sensing signal.

[0416] For example, ellipse 1 is determined based on the position of the second sensing transmitter, the first sensing signal, and the position of the first sensing receiver. Ellipse 1 is an ellipse with the positions of the first sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 1 is determined based on the position of the second sensing transmitter, the first receiving phase, the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the first sensing signal.

[0417] For example, ellipse 2 is determined based on the position of the first sensing transmitter, the second sensing signal, and the position of the first sensing receiver. Ellipse 2 is an ellipse with the positions of the first sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 2 is determined based on the position of the first sensing transmitter, the phase of the second sensing signal received by the first sensing receiver (e.g., the second receiving phase), the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0418] For example, ellipse 3 is determined based on the position of the first sensing transmitter, the position of the second sensing signal, and the position of the second sensing receiver. Ellipse 3 is an ellipse with the positions of the second sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 3 is determined based on the position of the first sensing transmitter, the second receiving phase, the position of the second sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0419] The intersection of ellipse 1, ellipse 2, and ellipse 3 is the location of the target.

[0420] For example, an ellipse 4 can be constructed, thereby determining the target information based on the intersection points of ellipses 1, 2, and 4; or the target information can be determined based on the intersection points of ellipses 1, 3, and 4. Ellipse 4 can be determined based on the sensing signals received by the first device, or it can be constructed based on the sensing signals received by the second device, or it can be determined based on the sensing signals received by the third device, or it can be determined based on the sensing signals received by the fourth device. This application does not limit this. Examples of constructing ellipse 4 based on sensing signals received by different devices are described below.

[0421] Example 1: Ellipse 4 is determined based on the sensing signal received by the first device.

[0422] In one implementation, ellipse 4 is determined based on the first sensing signal received by the first device. It is understood that an ellipse has already been constructed based on the first sensing signal, such as ellipse 1 in Figure 7A or Figure 7B. Ellipse 1 is determined by the first sensing signal received by the first sensing receiver. Therefore, in order to construct ellipse 4 differently from ellipse 1, the first device can also receive the first sensing signal through a sensing receiver different from the first sensing receiver. For example, the first device can also receive the first sensing signal through a second sensing receiver to construct ellipse 4, as shown in Figure 8A. In Figure 8A, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, RX1 is the first sensing receiver, RX2 is the second sensing receiver, ellipse 1 and ellipse 4 are determined based on the first sensing signal, ellipse 2 is determined based on the second sensing signal, and the target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4.

[0423] For example, ellipse 4 shown in Figure 8A is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0424] For example, ellipse 4 is determined based on the position of the first sensing transmitter, the position of the first sensing signal, and the position of the second sensing receiver. Ellipse 4 is an ellipse with the positions of the second sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the position of the first sensing transmitter, the phase of the first sensing signal received by the second sensing receiver (e.g., the third receiving phase), the position of the second sensing receiver, and the wavelength (or subcarrier frequency) of the first sensing signal.

[0425] In Figure 8A, the intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0426] In another implementation, ellipse 4 is determined based on the second sensing signal received by the first device. It is understood that an ellipse has been constructed based on the second sensing signal, such as ellipse 2 shown in FIG. 7A, or ellipse 3 shown in FIG. 7B. Ellipse 4 determined based on FIG. 7A and FIG. 7B are described below respectively.

[0427] For example, referring to Figure 7A, ellipse 2 is determined based on the second sensing signal received by the first sensing receiver. Therefore, in order to construct an ellipse 4 that is different from ellipse 2, the first device can also receive the second sensing signal through a sensing receiver different from the first sensing receiver. For example, the first device can also receive the second sensing signal through the second sensing receiver to construct ellipse 4, as shown in Figure 8B. In Figure 8B, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, RX1 is the first sensing receiver, RX2 is the second sensing receiver, ellipse 1 is determined based on the first sensing signal, and ellipses 2 and 4 are determined based on the second sensing signal. The target is located at the intersection of ellipses 1, 2, and 4.

[0428] Ellipse 4 shown in Figure 8B is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0429] Ellipse 4 is determined based on the position of the second sensing transmitter, the second sensing signal, and the position of the second sensing receiver. Ellipse 4 is an ellipse with the positions of the second sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the position of the second sensing transmitter, the phase of the second sensing signal received by the second sensing receiver (e.g., the fourth receiving phase), the position of the second sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0430] In Figure 8B, the intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0431] For example, referring to Figure 7B, ellipse 3 is determined based on the second sensing signal received by the second sensing receiver. Therefore, in order to construct an ellipse 4 that is different from ellipse 3, the first device can also receive the second sensing signal through a sensing receiver different from the second sensing receiver. For example, the first device can also receive the second sensing signal through the first sensing receiver to construct ellipse 4, as shown in Figure 8C. In Figure 8C, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, RX1 is the first sensing receiver, RX2 is the second sensing receiver, ellipse 1 is determined based on the first sensing signal, and ellipses 3 and 4 are determined based on the second sensing signal. The target is located at the intersection of ellipses 1, 3, and 4.

[0432] Ellipse 4 shown in Figure 8C is determined based on Figure 7B. Therefore, the relevant descriptions of ellipse 1 and ellipse 3 can be found in the descriptions of ellipse 1 and ellipse 3 in Figure 7B, and will not be repeated here.

[0433] Ellipse 4 is determined based on the position of the second sensing transmitter, the second sensing signal, and the position of the first sensing receiver. Ellipse 4 is an ellipse with the positions of the first sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the position of the second sensing transmitter, the second receiving phase, the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0434] In Figure 8C, the intersection of ellipse 1, ellipse 3, and ellipse 4 is the location of the target.

[0435] In another implementation, ellipse 4 is determined based on a third sensing signal received by the first device.

[0436] The third sensing signal is carried by the third sensing resource. The relationship between the third sensing resource and the first and second sensing resources can be referred to in the following text on the relationship between the third sensing resource and the first and second sensing resources, and will not be repeated here.

[0437] Optionally, the third sensing signal may be sent by the aforementioned first device, or by the aforementioned second device, or by other devices, such as a third device. This third device is different from the first and second devices. This application embodiment does not limit this; in this embodiment, the third sensing signal is taken as being sent by a third device. Specifically, it may be sent by the third sensing transmitter of the third device.

[0438] As mentioned above, in the embodiments of this application, taking the first device as a terminal device and the second device as a network device as an example, the third device being different from the first and second devices can be understood as the third device being a device different from the first and second devices, such as the third device being a terminal device different from the first device, or the third device being a network device different from the second device.

[0439] The third device being different from the first and second devices can also be understood as the third device and the first device being different devices within the same device. For example, the first device and the third device are different modules (e.g., processors, chips, chip systems, circuits, etc.) within a terminal device; or the third device and the second device are different devices within the same device. For example, the second device and the third device are different modules (e.g., processors, chips, chip systems, circuits, etc.) within a network device. This application embodiment does not limit this. In this application embodiment, the example given is that the third device is a different device from the first and second devices.

[0440] As mentioned above, the first device may include a first sensing receiver, through which the first device can receive a first sensing signal and a second sensing signal; or, the first device may also include a first sensing receiver and a second sensing receiver, whereby the first sensing receiver is used to receive the first sensing signal and the second sensing receiver is used to receive the second sensing signal.

[0441] Optionally, the first device may also receive the third sensing signal using a receiver that receives the first sensing signal and / or the second sensing signal. As one example, the first device may receive the first sensing signal, the second sensing signal, and the third sensing signal via the first sensing receiver. As another example, the first device may receive the first sensing signal and the third sensing signal via the first sensing receiver, and receive the second sensing signal via the second sensing receiver. As yet another example, the first device may receive the first sensing signal via the first sensing receiver, and receive the second and third sensing signals via the second sensing receiver.

[0442] Alternatively, the first device may receive the third sensing signal through a sensing receiver different from the one that receives the first and second sensing signals. As an example, the first device may receive the first and second sensing signals through the first sensing receiver, and the third sensing signal through the second sensing receiver. As another example, the first device may receive the first sensing signal through the first sensing receiver, the second sensing signal through the second sensing receiver, and the third sensing signal through another sensing receiver different from the first and second sensing receivers (e.g., a fifth sensing receiver). In this embodiment, the example is taken where the first device receives the first, second, and third sensing signals through the first sensing receiver.

[0443] Please refer to Figure 8D. In Figure 8D, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, TX3 is the sensing transmitter of the third device (e.g., the third sensing transmitter), RX1 is the first sensing receiver, ellipse 1 is determined based on the first sensing signal, ellipse 2 is determined based on the second sensing signal, and ellipse 4 is determined based on the third sensing signal. The target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4.

[0444] Ellipse 4 shown in Figure 8D is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0445] Ellipse 4 is determined based on the position of the third sensing transmitter, the third sensing signal, and the position of the first sensing receiver. Ellipse 4 is an ellipse with the positions of the first sensing receiver and the third sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the position of the third sensing transmitter, the phase of the third sensing signal received by the first sensing receiver (e.g., the fifth receiving phase), the position of the first sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0446] The intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0447] Example 2: Ellipse 4 is determined based on the sensing signal received by the second device.

[0448] In one implementation, ellipse 4 is determined based on the first sensing signal received by the second device. It is understood that an ellipse has already been constructed based on the first sensing signal, such as ellipse 1 in Figure 7A or Figure 7B. Ellipse 1 is determined by the first sensing signal received by the sensing receiver of the first device. Therefore, to ensure that the constructed ellipse 4 differs from ellipse 1, the first sensing signal can also be received by the second device to construct ellipse 4, as shown in Figure 8E. In Figure 8E, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, RX1 is the first sensing receiver, and RX3 is the sensing receiver of the second device (e.g., a third sensing receiver). Ellipses 1 and 4 are determined based on the first sensing signal, ellipse 2 is determined based on the second sensing signal, and the target is located at the intersection of ellipses 1, 2, and 4.

[0449] For example, please refer to Figure 8E. Ellipse 4 shown in Figure 8E is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0450] Ellipse 4 is determined based on the positions of the second sensing transmitter, the first sensing signal, and the third sensing receiver. Ellipse 4 is an ellipse with the positions of the third sensing receiver and the second sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the positions of the second sensing transmitter, the phase of the first sensing signal received by the third sensing receiver (e.g., the sixth receiving phase), the wavelength (or subcarrier frequency) of the first sensing signal.

[0451] In Figure 8E, the intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0452] In another implementation, ellipse 4 is determined based on the second sensing signal received by the first device. It is understood that an ellipse has already been constructed based on the second sensing signal, such as ellipse 2 shown in Figure 7A, or ellipse 3 shown in Figure 7B. Ellipse 2 and ellipse 3 are determined by the second sensing signal received by the sensing receiver of the first device. Therefore, in order to construct ellipse 4 differently from ellipse 2 and ellipse 3, the second sensing signal can also be received by the second device to construct ellipse 4 (not shown in the figures). The target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4. Alternatively, the target is located at the intersection of ellipse 1, ellipse 3, and ellipse 4.

[0453] For example, ellipse 4 is determined based on the position of the first sensing transmitter, the second sensing signal, and the position of the third sensing receiver. Ellipse 4 is an ellipse with the positions of the third sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the positions of the first sensing transmitter, the third sensing receiver, the phase of the second sensing signal received by the third sensing receiver (e.g., the seventh receiving phase), and the wavelength (or subcarrier frequency) of the third sensing signal.

[0454] The location of the target is the intersection of ellipse 1, ellipse 2 and ellipse 4, or the location of the target is the intersection of ellipse 1, ellipse 3 and ellipse 4.

[0455] In another implementation, ellipse 4 is determined based on a third sensing signal received by the second device.

[0456] The description of the third sensing signal can be found in Example 1, and will not be repeated here. The second device can receive the third sensing signal through the third sensing receiver to construct ellipse 4 (not shown in the figure). The target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4. Alternatively, the target is located at the intersection of ellipse 1, ellipse 3, and ellipse 4.

[0457] For example, ellipse 4 is determined based on the position of the third sensing transmitter, the third sensing signal, and the position of the third sensing receiver. Ellipse 4 is an ellipse with the positions of the third sensing receiver and the third sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the positions of the third sensing transmitter and the third sensing receiver, the phase of the third sensing signal received by the third sensing receiver (e.g., the eighth receiving phase), and the wavelength (or subcarrier frequency) of the third sensing signal.

[0458] The location of the target is the intersection of ellipse 1, ellipse 2 and ellipse 4, or the location of the target is the intersection of ellipse 1, ellipse 3 and ellipse 4.

[0459] Example 3: Ellipse 4 is determined based on the sensing signal received by the third device.

[0460] In one implementation, ellipse 4 is determined based on the first sensing signal received by the third device. It is understood that an ellipse has already been constructed based on the first sensing signal, such as ellipse 1 in Figure 7A or Figure 7B. Ellipse 1 is determined by the first sensing signal received by the first sensing receiver of the first device. Therefore, to ensure that the constructed ellipse 4 differs from ellipse 1, the first sensing signal can also be received by the third device to construct ellipse 4, as shown in Figure 8F. In Figure 8F, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, RX1 is the first sensing receiver, and RX4 is the sensing receiver of the third device (e.g., the fourth sensing receiver). Ellipses 1 and 4 are determined based on the first sensing signal, ellipse 2 is determined based on the second sensing signal, and the target is located at the intersection of ellipses 1, 2, and 4.

[0461] For example, please refer to Figure 8F. Ellipse 4 shown in Figure 8F is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0462] For example, ellipse 4 is determined based on the position of the second sensing transmitter, the first sensing signal, and the position of the fourth sensing receiver. Ellipse 4 is an ellipse with the position of the fourth sensing receiver and the position of the second sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the position of the second sensing transmitter, the phase of the first sensing signal received by the fourth sensing receiver (e.g., the ninth receiving phase), the position of the fourth sensing receiver, and the wavelength (or subcarrier frequency) of the first sensing signal.

[0463] In Figure 8F, the intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0464] In another implementation, ellipse 4 is determined based on the second sensing signal received by the third device. It is understood that an ellipse, such as ellipse 2 shown in Figure 7A, has already been constructed based on the second sensing signal. Ellipse 2 and ellipse 3 are determined by the second sensing signal received by the sensing receiver of the first device. Therefore, to ensure that the constructed ellipse 4 differs from ellipses 2 and 3, the second sensing signal can also be received by the third device to construct ellipse 4, as shown in Figure 8G. In Figure 8G, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, RX1 is the first sensing receiver, and RX4 is the sensing receiver of the third device (e.g., a fourth sensing receiver). Ellipse 1 is determined based on the first sensing signal, and ellipses 2 and 4 are determined based on the second sensing signal. The target is located at the intersection of ellipses 1, 2, and 4.

[0465] For example, please refer to Figure 8G. Ellipse 4 shown in Figure 8G is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0466] For example, ellipse 4 is determined based on the positions of the first sensing transmitter, the second sensing signal, and the fourth sensing receiver. Ellipse 4 is an ellipse with the positions of the fourth sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the positions of the first sensing transmitter, the phase of the second sensing signal received by the fourth sensing receiver (e.g., the tenth receiving phase), the position of the fourth sensing receiver, and the wavelength (or subcarrier frequency) of the second sensing signal.

[0467] In Figure 8G, the intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0468] In another implementation, ellipse 4 is determined based on a third sensing signal received by a third device.

[0469] The description of the third sensing signal can be found in Example 1, and will not be repeated here. The third device can receive the third sensing signal through the fourth sensing receiver to construct ellipse 4, as shown in Figure 8H. In Figure 8H, TX1 is the second sensing transmitter, TX2 is the first sensing transmitter, TX3 is the third sensing transmitter, RX1 is the first sensing receiver, RX4 is the fourth sensing receiver, ellipse 1 is determined based on the first sensing signal, ellipse 2 is determined based on the second sensing signal, and ellipse 4 is determined based on the third sensing signal. The target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4.

[0470] For example, please refer to Figure 8H. Ellipse 4 shown in Figure 8H is determined based on Figure 7A. Therefore, the relevant descriptions of ellipse 1 and ellipse 2 can be found in the descriptions of ellipse 1 and ellipse 2 in Figure 7A, and will not be repeated here.

[0471] For example, ellipse 4 is determined based on the position of the third sensing transmitter, the third sensing signal, and the position of the fourth sensing receiver. Ellipse 4 is an ellipse with the positions of the fourth sensing receiver and the third sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the position of the third sensing transmitter, the phase of the third sensing signal received by the fourth sensing receiver (e.g., the eleventh receiving phase), the position of the fourth sensing receiver, and the wavelength (or subcarrier frequency) of the third sensing signal.

[0472] In Figure 8H, the intersection of ellipse 1, ellipse 2 and ellipse 4 is the location of the target.

[0473] Example 4: Ellipse 4 is determined based on the sensing signal received by the fourth device.

[0474] In one implementation, ellipse 4 is determined based on the first sensing signal received by the fourth device.

[0475] In this embodiment, the fourth device does not transmit any of the first, second, or third sensing signals; that is, in this application embodiment, the fourth device does not transmit any sensing signals. In other words, the fourth device is different from any of the first, second, or third devices.

[0476] As mentioned above, in the embodiments of this application, the first device is a terminal device, the second device is a network device, and the third device is a different device from the first and second devices. The fourth device being different from any of the first, second, or third devices can be understood as the fourth device being a different device from any of the first, second, or third devices. For example, the fourth device is a different terminal device from the first device, or a different network device from the second device, or the fourth device is a different terminal device (or network device) from the third device.

[0477] The fourth device differs from any of the first, second, or third devices. This can also be understood as the fourth device and the first device being different devices within the same device, such as different modules (e.g., processors, chips, chip systems, circuits, etc.) within a terminal device; or the fourth device and the second device are different devices within the same device, such as different modules (e.g., processors, chips, chip systems, circuits, etc.) within a network device; or the fourth device and the third device are different devices within the same device, such as different modules (e.g., processors, chips, chip systems, circuits, etc.) within a terminal device (network device). This application does not limit this to specific cases. In this application embodiment, the example given is that the fourth device is a different device from any of the first, second, or third devices.

[0478] It is understood that an ellipse has been constructed based on the first sensing signal, such as ellipse 1 in Figure 7A or Figure 7B. Ellipse 1 is determined by the first sensing signal received by the sensing receiver of the first device. Therefore, in order to construct an ellipse 4 that is different from ellipse 1, the first sensing signal can also be received by the sensing receiver of the fourth device (e.g., the fifth sensing receiver) to construct ellipse 4 (not shown in the figure).

[0479] Ellipse 4 is determined based on the first sensing signal. For example, ellipse 4 is determined based on the position of the second sensing transmitter, the position of the fifth sensing receiver, the phase of the first sensing signal received by the fifth sensing receiver (e.g., the twelfth receiving phase), and the wavelength (or subcarrier frequency) of the first sensing signal. Ellipse 4 is an ellipse with the position of the fifth sensing receiver and the position of the second sensing transmitter as its foci.

[0480] In another implementation, ellipse 4 is determined based on the second sensing signal received by the fourth device.

[0481] It is understood that an ellipse has been constructed based on the second sensing signal, such as ellipse 2 shown in Figure 7A, or ellipse 3 shown in Figure 7B. Ellipse 2 or ellipse 3 is determined by the second sensing signal received by the sensing receiver of the first device. Therefore, in order to construct an ellipse 4 that differs from ellipse 2 or ellipse 3, the second sensing signal can also be received by a fifth sensing receiver to construct ellipse 4 (not shown in the figures). The target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4. Alternatively, the target is located at the intersection of ellipse 1, ellipse 3, and ellipse 4.

[0482] For example, ellipse 4 is determined based on the position of the first sensing transmitter, the second sensing signal, and the position of the fifth sensing receiver. Ellipse 4 is an ellipse with the positions of the fifth sensing receiver and the first sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the second sensing signal, for example, based on the position of the first sensing transmitter, the position of the fifth sensing receiver, the phase of the second sensing signal received by the fifth sensing receiver (e.g., the thirteenth receiving phase), and the wavelength (or subcarrier frequency) of the second sensing signal.

[0483] The location of the target is the intersection of ellipse 1, ellipse 2 and ellipse 4, or the location of the target is the intersection of ellipse 1, ellipse 3 and ellipse 4.

[0484] In another implementation, ellipse 4 is determined based on the third sensing signal received by the fourth device.

[0485] The description of the third sensing signal can be found in Example 1, and will not be repeated here. The fourth device can receive the third sensing signal through the fifth sensing receiver to construct ellipse 4 (not shown in the figure). The target is located at the intersection of ellipse 1, ellipse 2, and ellipse 4. Alternatively, the target is located at the intersection of ellipse 1, ellipse 3, and ellipse 4.

[0486] For example, ellipse 4 is determined based on the position of the third sensing transmitter, the third sensing signal, and the position of the fifth sensing receiver. Ellipse 4 is an ellipse with the positions of the fifth sensing receiver and the third sensing transmitter as its foci. Specifically, ellipse 4 is determined based on the positions of the third sensing transmitter, the fifth sensing receiver, the phase of the third sensing signal received by the fifth sensing receiver (e.g., the fourteenth receiving phase), and the wavelength (or subcarrier frequency) of the third sensing signal.

[0487] The location of the target is the intersection of ellipse 1, ellipse 2 and ellipse 4, or the location of the target is the intersection of ellipse 1, ellipse 3 and ellipse 4.

[0488] As mentioned above, after constructing ellipse 4, target information can be determined based on the intersection points of ellipse 1, ellipse 2, and ellipse 4, or based on the intersection points of ellipse 1, ellipse 3, and ellipse 4. The determination of target information based on the intersection points of ellipse 1, ellipse 2, and ellipse 4, or based on the intersection points of ellipse 1, ellipse 3, and ellipse 4, can be implemented by the first device or by other devices. These other devices can be any of the second, third, fourth, or fifth devices, or they can be sensing network elements, etc. This application embodiment does not limit this.

[0489] If the target information is determined to be realized by the first device, the first device can also receive first information, which can be determined by the second device based on at least one of the first, second, or third sensing signals; and / or, the first information can be determined by the third device based on at least one of the first, second, and third sensing signals; and / or, the first information can be determined by the fourth device based on at least one of the first, second, and third sensing signals. That is, the first information comes from at least one of the second, third, or fourth devices.

[0490] As an example, the first information may include received information of the sensing signal (e.g., received phase and / or received amplitude). For example, the first information may include received information of at least one of a first sensing signal, a second sensing signal, or a third sensing signal. Optionally, the first information may also include at least one of the following: the location of the sensing transmitter, the location of the sensing receiver, the distance between the sensing transmitter and the sensing receiver, and the wavelength (or subcarrier frequency) of the sensing signal. The descriptions of the sensing transmitter and sensing receiver can refer to the relevant descriptions of the sensing receiver and sensing transmitter included in the device corresponding to the first information, such as the relevant descriptions of the sensing receiver and sensing transmitter included in Examples 2 to 4, which will not be repeated here. Taking the first information being transmitted by the second device as an example, the first information may also include at least one of the following: the location of the second sensing transmitter, the location of the third sensing receiver, the wavelength (or subcarrier frequency) of the first sensing signal, and the distance between the third sensing receiver and the second sensing transmitter.

[0491] As another example, the first information includes information about an ellipse determined based on the received sensing signal. For example, the first information includes information about an ellipse determined based on at least one of the received first sensing signal, second sensing signal, or third sensing signal, such as the information about ellipse 4 in Examples 2 to 4. Taking the example that the first information is sent by the second device, the first information may include information about at least one of the three types of ellipse 4 described in Example 2.

[0492] If it is determined that the target information is implemented by another device, the first device can also send second information to that other device.
