Antenna resource allocation method and communication device Technical Field

[0001] The embodiments of the present application relate to the field of communication perception, and in particular to an antenna resource allocation method and a communication device. Background Art

[0002] With the development and advancement of communication technology, base stations in future cellular networks will not only enable the interconnection of people and objects, but will also possess perception capabilities. The enabling technology that enables the coexistence, mutual assistance, and reciprocity of communication and perception functions is called integrated sensing and communication (ISAC). ISAC integrates communication and perception functions into a single base station system, allowing communication and perception to share the same hardware resources. Massive multiple input multiple output (MIMO) antenna arrays can have up to 32×32 antennas. In the context of integrated sensing, antennas can be used not only for communication but also for perception. However, how to allocate antenna resources for communication and perception has become a pressing issue.

[0003] Summary of the Invention

[0004] The embodiments of the present application provide an antenna resource allocation method and a communication device, which can realize the allocation of antenna resources for communication and perception.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a method for allocating antenna resources is provided. The method can be executed by a first device, or by a component of the first device, such as a processor, chip, or chip system of the first device, or by a logic module or software that can implement all or part of the functions of the first device. The first device can be a device that sends a perception signal (such as a first communication device), a device that receives an echo signal (such as a second communication device), or a device other than a device that sends a perception signal and a device that receives an echo signal (such as a third communication device). The method includes: obtaining perception information of the first perception, and determining first information based on the perception information of the first perception. The perception information of the first perception is used to indicate the area where the perception target is located, and the first information includes a target array pattern and a scaling factor. The target array pattern and the scaling factor are used to determine the antenna array elements occupied by the second perception.

[0007] Based on this antenna resource allocation method, which uses a phased sensing approach (e.g., first sensing and second sensing), a first device can determine first information based on sensing information from the first sensing. The first information includes a target array pattern and scaling factor for determining antenna elements occupied by the second sensing. This allows a sensing device (e.g., a device sending a sensing signal or a device receiving an echo signal) to allocate antenna resources for sensing and communication based on the first information to perform the second sensing. This reduces interference between sensing and communication, improves antenna resource utilization, and enhances the accuracy of the second sensing.

[0008] In one possible design, the antenna array elements occupied by the second perception are antenna array elements in the first antenna array having an aperture of the first aperture, and the aperture of the first antenna array is greater than or equal to the first aperture. The phrase "the aperture of the first antenna array is greater than or equal to the first aperture" can also be expressed as "the first aperture is less than or equal to the aperture of the first antenna array." In this embodiment of the present application, the first aperture is also greater than the aperture of the antenna array formed by the antenna array elements occupied by the first perception, to improve perception accuracy.

[0009] In one possible design scheme, the target array pattern is used to determine the number and relative positions of the antenna elements occupied by the second perception, and the scaling factor is used to determine the element spacing of the antenna elements occupied by the second perception. In an embodiment of the present application, the target array pattern can be mapped to obtain an antenna array, and the parameters of the target array pattern include the average element spacing, the number of elements, the center wavelength of the antenna operation, and the array factor for indicating the mapped antenna array. According to the target array pattern, the number and relative positions of the antenna elements occupied by the second perception can be determined, and according to the scaling factor, the specific position of the antenna elements occupied by the second perception in the first antenna array can be determined. Therefore, based on the selection of the target array pattern and the determination of the scaling factor, not only can the antenna elements used for secondary perception be determined, but also the perception precision and accuracy of the secondary perception can be improved.

[0010] In one possible design scheme, the target array pattern can be determined based on the first angle range and the spatial resolution, and the first angle range is determined based on the perception information of the first perception. In the embodiment of the present application, the spatial resolution represents the resolution requirement for the target area. The higher the spatial resolution, the smaller the details or features that can be distinguished. The spatial resolution can be pre-agreed or pre-configured to determine the antenna array elements used for secondary perception to ensure perception accuracy. The first angle range is used to feedback the angle range of the perception target relative to the device for sending the perception signal or the device for receiving the echo signal. The first angle range can not only be used to determine the first information, but also as the beam scanning range for sending the perception signal or receiving the echo signal during the second perception, so as to improve the perception efficiency and accuracy of the second perception.

[0011] In one possible design scheme, the first angle range can be the angle range for sending the perception signal of the second perception, or the first angle range can be the angle range for receiving the second echo signal, where the second echo signal is the signal of the perception signal of the second perception after passing through the perception target. In the embodiment of the present application, the first angle range is calculated based on the perception information of the first perception, and is used to feedback the angle range of the perception target relative to the device for sending the perception signal or the device for receiving the echo signal. Therefore, the first angle range can not only be used to determine the first information, but also can be used as the beam scanning range for sending the perception signal or receiving the echo signal during the second perception, so as to improve the perception efficiency and accuracy of the second perception.

[0012] In one possible design scheme, the scaling factor can be determined based on the first angle range and the first parameter of the target array pattern, where the first parameter represents the electrical size of the average element spacing of the antenna array mapped by the target array pattern. In an embodiment of the present application, the first parameter can be used to characterize the relative position of the antenna array occupied by the second perception. Based on this design scheme, the scaling factor is set on the basis of ensuring the resolution and grating lobe level of the secondary perception. The scaling factor is performed by scaling the average element spacing of the antenna array mapped by the target array pattern to determine the element spacing between the antenna elements occupied by the second perception, that is, to determine the antenna array used by the second perception.

[0013] In one possible design scheme, the scaling factor can be determined based on the maximum element spacing that can be set for the antenna elements occupied by the second perception, the operating wavelength of the antenna in the first antenna array, and the first parameter, and the maximum element spacing is determined based on the first angle range.

[0014] In one possible design, the scaling factor can satisfy the following relationship: Where S is the scaling factor, d max is the maximum element spacing, λ is the operating wavelength of the antenna in the first antenna array, k p is the first parameter. In the embodiment of the present application, It can also be expressed as k0 to indicate the maximum electrical size of the array element spacing that can be set for the antenna array elements occupied by the second perception. Therefore, the scaling factor can also be expressed as

[0015] In one possible design, the maximum element spacing may be determined based on a maximum sine value and an operating wavelength of the antennas in the first antenna array, where the maximum sine value is the maximum value among the absolute values ​​of the sine values ​​calculated based on the angle values ​​in the first angle range.

[0016] In the embodiment of the present application, the maximum element spacing is determined to ensure that there is no ambiguity (no grating lobe) in the perception within the first angle range, and the element spacing of the antenna elements occupied by the second perception needs to satisfy d≤d max .

[0017] In one possible design solution, the maximum element spacing can satisfy the following relationship: where |sinθ| max is the maximum sine value.

[0018] In one possible design solution, the maximum array element spacing may be determined according to the length of the first angular range and the operating wavelength of the antennas in the first antenna array.

[0019] In one possible design solution, the maximum element spacing can satisfy the following relationship: Wherein, A is the length of the first angle range.

[0020] In a possible design solution, the first parameter may satisfy the following relationship: Among them, d p is the average element spacing of the antenna array mapped by the target array pattern, λ p The central wavelength at which the antennas in the antenna array operate, as mapped by the target array pattern.

[0021] In one possible design, the method provided in an embodiment of the present application may further include: sending first information. In this design, the first device, as a computing node, does not need to perform sensing antenna selection, and the second device, as a communication device, performs sensing antenna selection. Thus, after determining the first information, the first device needs to send the first information to the second device, so that the second device can determine the antenna array elements occupied by the second sensing based on the first information, thereby performing more accurate secondary sensing.

[0022] In a possible design scheme, the method provided in the embodiment of the present application may further include: sending a second information. The second information is used to indicate a first angle range, and the first angle range is the angle range for sending the second perceived perception signal, or the first angle range is the angle range for receiving the second echo signal, and the second echo signal is the signal of the second perceived perception signal after passing through the perception target. Based on this design scheme, the first device may also send the second information to the second device. In the case where the second device is a device for sending a perception signal, the first angle range is the angle range for sending the second perceived perception signal, so that the second device can scan and send the second perceived perception signal within the first angle range, thereby improving perception efficiency and accuracy. In the case where the second device is a device for receiving an echo signal, the first angle range is the angle range for receiving the second echo signal, so that the second device can scan and receive the second echo signal within the first angle range, thereby improving perception efficiency and accuracy.

[0023] In one possible design solution, the method provided in an embodiment of the present application may further include: determining third information based on the perception information of the first perception. The third information is used to indicate a second angle range. If the first angle range is the angle range for transmitting the perception signal of the second perception, the second angle range is the angle range for receiving the second echo signal; if the first angle range is the angle range for receiving the second echo signal, the second angle range is the angle range for transmitting the perception signal of the second perception.

[0024] In one possible design, the first angle range is the angle range for sending the perception signal of the second perception; obtaining the perception information of the first perception may include: receiving a first echo signal; and determining the perception information of the first perception based on the first echo signal. Based on this design, the first device may be a device that receives the echo signal (such as a second communication device), which may locally determine the first information based on the perception information of the first perception, thereby indicating the first information to the second device. The second device is then a device that sends the perception signal (such as the first communication device), so that the second device can determine the antenna array element occupied by the second perception based on the first information, and use the antenna array element occupied by the second perception to send the perception signal of the second perception, that is, perform secondary perception.

[0025] In one possible design, the method provided in an embodiment of the present application may further include: receiving a second echo signal, the second echo signal being a signal resulting from the second perception signal passing through a perception target; and determining perception information of the second perception based on the second echo signal. Based on this design, the first device is a device that receives the echo signal, and the perception information of the second perception may be determined based on the signal resulting from the second perception signal passing through the perception target.

[0026] In one possible design, the first angle range is the angle range for receiving the second echo signal; obtaining the perception information of the first perception may include: sending the perception signal of the first perception; receiving the perception information of the first perception. Based on this design, the first device may be a device that sends the perception signal (such as a first communication device), which can determine the first information based on the perception information of the first perception obtained from the second device, thereby indicating the first information to the second device. The second device is then a device that receives the echo signal (such as a second communication device), so that the second device can determine the antenna array element occupied by the second perception based on the first information, and use the antenna array element occupied by the second perception to receive the second echo signal. The second echo signal is a signal of the perception signal of the second perception after being acted upon by the perception target, that is, secondary perception is performed.

[0027] In one possible design, the method provided in an embodiment of the present application may further include: determining third information based on the perception information of the first perception, and transmitting the third information. The third information is used to indicate a second angular range, where the second angular range is the angular range for transmitting the perception signal of the second perception, or the second angular range is the angular range for receiving a second echo signal, where the second echo signal is a signal of the perception signal of the second perception passing through the perception target.

[0028] In a possible design scheme, the second angle range is the angle range for sending the perception signal of the second perception; obtaining the perception information of the first perception may include: using a second antenna array to receive the first echo signal, the second antenna array being an antenna array with an aperture of the second aperture in the first antenna array, and the second aperture being smaller than the first aperture. The perception information of the first perception is determined according to the first echo signal. Based on this design scheme, the first device may be a device that receives the echo signal (such as a second communication device), and is deployed with a first antenna array. When allocating antennas for perception and communication to the first antenna array, the first device may locally determine the first information based on the perception information of the first perception, thereby determining the antenna array element occupied by the second perception in the first antenna array based on the first information. Among them, the aperture of the antenna array used by the first device when performing the first perception is smaller than the aperture of the antenna array used when performing the second perception.

[0029] In one possible design, the second angle range is the angle range for receiving the second echo signal; obtaining the perception information of the first perception may include: using a second antenna array to send the perception signal of the first perception, the second antenna array being an antenna array in the first antenna array with an aperture of the second aperture, the second aperture being smaller than the first aperture; and receiving the perception information of the first perception. Based on this design, the first device may be a device that sends the perception signal (such as a first communication device) and is deployed with a first antenna array. When allocating antennas for perception and communication on the first antenna array, after using the second antenna array to send the perception signal of the first perception, the first device may determine the first information based on the perception information of the first perception obtained from the device that receives the echo signal (such as the second communication device), thereby determining the antenna array elements occupied by the second perception in the first antenna array based on the first information. The aperture of the antenna array used by the first device for the first perception is smaller than the aperture of the antenna array used for the second perception.

Based on this design, the first device may be a device other than the device that sends the perception signal and the device that receives the echo signal (e.g., a third communication device). As a control node, the first device determines the first information based on the first-perceived perception information obtained from the device that receives the echo signal (e.g., the second communication device), and sends the first information to the second device. In this case, the second device may be the device that sends the perception signal or the device that receives the echo signal and is deployed with the first antenna array.

[0031] In one possible design, the method provided in an embodiment of the present application may further include: determining second information and third information based on the perception information of the first perception, the second information being used to indicate the first angular range, and the third information being used to indicate the second angular range. Wherein, if the first angular range is the angular range for transmitting the perception signal of the second perception, the second angular range is the angular range for receiving the second echo signal; and if the first angular range is the angular range for receiving the second echo signal, the second angular range is the angular range for transmitting the perception signal of the second perception, and the second echo signal is the second perception signal after it has passed through the perception target. The second information and the third information are transmitted. Thus, if the first device is a device other than the device that transmits the perception signal and the device that receives the echo signal, the first device transmits the second information for the device that transmits the perception signal and the device that receives the echo signal that requires perception antenna selection, and transmits the third information for the device that transmits the perception signal and the device that receives the echo signal that does not require perception antenna selection.

[0130] To better understand the embodiments of the present application, the following first introduces the system architecture involved in the embodiments of the present application:

[0131] The embodiments of the present application will present various aspects, embodiments, or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the figures. Furthermore, combinations of these solutions may also be used.

[0132] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless fidelity (Wi-Fi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, 4th generation (4G) mobile communication systems, such as long term evolution (LTE) systems, world-wide interoperability for microwave access (WiMAX) communication systems, 5th generation (5G) mobile communication systems, such as new radio (NR) systems, and future communication systems, such as 6th generation (6G) mobile communication systems.

[0133] The following describes the related technologies involved in the embodiments of this application.

[0134] 1. ISAC

[0135] ISAC can also be referred to as joint communications and sensing (JCS) or joint communications and sensing (JCAS). In 6G mobile communication systems, higher frequency bands (millimeter wave and even terahertz), wider bandwidths, and larger antenna arrays enable high-precision, high-resolution perception. This makes ISAC possible within a single system, allowing communication and perception functions to complement each other. On the one hand, the entire communication network can function as a massive sensor. Network elements transmit and receive wireless signals, leveraging the transmission, reflection, and scattering of radio waves to better perceive and understand the physical world. By extracting distance, speed, and angle information from wireless signals, a wide range of new services can be provided, including high-precision positioning, gesture capture, motion recognition, passive object detection, imaging, and environmental reconstruction, realizing the "Network as a Sensor." On the other hand, the high-precision positioning, imaging, and environmental reconstruction capabilities provided by perception can help improve communication performance, for example, by enabling more accurate beamforming and faster recovery from beam failures, enabling "perception-assisted communication." Perception also serves as a "new channel" for observing and sampling the physical and biological worlds, connecting them to the digital world. The application scenarios of future 6G ISAC systems are likely to include ultra-high-precision positioning, synchronous imaging, map construction, and human sensory enhancement.

[0136] The perception process is achieved using perception signals. Perception signals can refer to signals used to perceive or detect targets, or to perceive or detect environmental information. For example, perception signals can be electromagnetic waves sent by network devices to perceive environmental information.

[0137] The echo signal is the signal generated by the perception signal passing through the perception target in the environment. The time delay of the echo signal relative to the transmitted perception signal reflects the distance of the perception target; the Doppler frequency shift of the echo signal relative to the transmitted perception signal reflects the speed of the perception target.

[0138] In the embodiment of the present application, the perception signal is a signal obtained by the perception target being acted upon, and may also be referred to as a signal obtained by the perception signal being reflected by the perception target, a signal obtained by the perception signal being refracted by the perception target, a signal obtained by the perception signal being diffracted by the perception target, a signal obtained by the perception signal being transmitted through the perception target, a signal obtained by the perception signal being scattered or diffracted by the perception target, and the like, without specific limitation.

[0139] Sensing targets can include various tangible objects on the ground, such as mountains, forests, and buildings. They can also include movable objects such as vehicles and terminal devices. A sensing target is a target that a sensing device with sensing capabilities can perceive and that can feed electromagnetic waves back to the network device. Sensing targets can also be referred to as detected targets, sensed objects, detected objects, or sensed devices, without limitation.

[0140] 2. MIMO technology

[0141] MIMO technology refers to the technology of using multiple antennas to send and receive signals in the field of wireless communications. Among them, network equipment and terminal equipment can obtain power gain, spatial diversity gain, and spatial multiplexing gain by using MIMO technology. Spatial diversity can refer to the introduction of signal redundancy in space to achieve the purpose of diversity. For example, the terminal device sends two orthogonal data streams to each other through two antennas, thereby obtaining diversity gain. Spatial multiplexing can refer to sending multiple independent data streams on the same time-frequency resource on each antenna to achieve the purpose of improving spectrum efficiency without increasing spectrum resources. For example, the terminal device can map the uplink data layer (layer mapper) into two independent data streams and send them simultaneously through multiple antennas, so that the spatial resources on the same time-frequency resource can be reused.

[0142] 3. Precoding technology

[0143] The transmitting device (such as a network device) can process the signal to be transmitted with the help of a precoding matrix that matches the channel resource when the channel state is known, so that the precoded signal to be transmitted is adapted to the channel, thereby reducing the complexity of the receiving device in eliminating the influence between channels. Among them, by precoding the signal to be transmitted, the quality of the received signal (such as signal to interference plus noise ratio (SINR)) can be improved. Therefore, by adopting the precoding technology, it is possible to realize that the transmitting device and multiple receiving devices transmit signals on the same time-frequency resources, that is, multiple user multiple input multiple output (MU-MIMO) is realized. It should be noted that the relevant description of the precoding technology is only for ease of understanding and is not intended to limit the scope of protection of the embodiments of the present application. In the specific implementation process, the transmitting device can also perform precoding in other ways. For example, when the channel information (such as but not limited to the channel matrix) cannot be known, a pre-set precoding matrix or a weighted processing method is used for precoding. For the sake of brevity, its specific content is not repeated here.

[0144] Exemplarily, the process of data precoding mapping at the object layer is shown in Figure 1. The transmitting device sequentially performs scrambling, modulation mapping, layer mapping, precoding, and resource element (RE) resource mapping (mapping to antenna ports) on the codeword to generate orthogonal frequency division multiplexing (OFDM) symbols and transmit them through the antenna port.

[0145] Among them, the implementation of precoding technology relies on CSI measurement and feedback. Currently, the process of network equipment and terminal equipment performing CSI measurement includes: the network equipment sends channel measurement configuration information to the terminal equipment to notify the terminal equipment of the time to perform channel measurement and related configuration information. Furthermore, the network equipment sends a pilot signal for channel measurement, also known as a reference signal, such as a channel state information reference signal (CSI-RS), to the terminal equipment, so that the terminal equipment can use the pilot signal to perform channel estimation to obtain CSI, and feedback the CSI to the network equipment through the physical uplink shared channel (PUSCH) or the physical uplink control channel (PUCCH). Among them, CSI can include one or more of the following: precoding matrix indicator (PMI), channel quality indicator (CQI), CSI-RS resource indicator (CRI), layer indicator (LI), and rank indicator (RI).

[0146] 4. Antenna

[0147] An antenna is an electronic device used to transmit or receive radio or electromagnetic waves. Physically, an antenna is a combination of one or more conductors that generates a radiated electromagnetic field due to an applied alternating voltage and an associated alternating current. Alternatively, it can be exposed to electromagnetic waves, where the field induces an alternating current within the antenna and an alternating voltage at its terminals. The bandwidth of an antenna refers to the frequency range over which it operates effectively.

[0148] 5. Array Elements

[0149] An array element is a component of an antenna array. Generally, an antenna array is composed of array elements, which are divided into transmitting array elements and receiving array elements. Transmitting array elements are used to radiate electromagnetic waves into space, and receiving array elements are used to receive electromagnetic waves in space. Antenna arrays can be divided into two types of array element groups according to their functions, one type of array element group is used as a transmitting array element, and the other type of array element group is used as a receiving array element. For example, taking the minimum unit as an example, the antenna array includes two array element groups, namely a first array element group and a second array element group. The first array element group is used as a transmitting array element, and the second array element group is used as a receiving array element, and each array element group includes at least two array elements. In the embodiment of the present application, an array element is equivalent to an antenna, an array element can also be called an antenna array element, and an antenna array can also be called an antenna array surface.

[0150] The antenna array can be arranged in either one or two dimensions. In a one-dimensional antenna array, all elements (including transmit and receive elements) are located in a single linear dimension, as shown in Figure 2 (a).

[0151] All elements of a two-dimensional antenna array, including both transmitting and receiving elements, are located on a single plane, rather than on the same linear dimension. For example, in a two-dimensional antenna array with M rows and N columns, as shown in Figure 2(b), the elements are arranged in a rectangular structure, with the spacing between the M rows and N columns being the same. M and N are both positive integers, and can be equal or unequal. In other words, the elements of a two-dimensional antenna array can be arranged in a rectangular or square structure. Compared to a one-dimensional antenna array, two-dimensional antenna elements can accurately reflect the actual situation of the target during perception. The two-dimensional antenna array structure can improve imaging results, depict more target information, and meet the user's imaging needs.

[0152] The element spacing is the distance between two adjacent elements of the antenna array. Usually, the elements of the antenna array are arranged at equal intervals. For example, the two-dimensional antenna array element shown in (b) of Figure 2 uses the distance between the center points of two adjacent antenna elements as the element spacing d. The element spacing setting is related to the working wavelength λ of the antenna. Based on different communication scenarios, the element spacing is usually set to λ is the wavelength corresponding to the center carrier, which can be understood as the working wavelength of the antenna or the center wavelength of the signal sent or received by the antenna.

[0153] In embodiments of the present application, the aperture of an antenna array can be measured by its lateral, vertical, or diagonal dimensions, or by its area. It can also be measured by its electrical dimensions, which are the ratio of the physical dimensions of the antenna array's aperture to the carrier wavelength. The aperture of an antenna array depends on the number and arrangement of antennas in the array. For a two-dimensional antenna array with M rows and N columns, as shown in Figure 2(b), where the element spacing is d, the aperture of the antenna array is (M-1)×d×(N-1)×d.

[0154] In addition, in the embodiments of the present application, "small aperture" and "large aperture" both refer to relative aperture sizes. For example, the antenna array with 4 rows and 4 columns is selected from the two-dimensional antenna array with M rows and N columns shown in (b) of Figure 2. The aperture of the antenna array with 4 rows and 4 columns is smaller than the aperture of the two-dimensional antenna array with M rows and N columns. At this time, the aperture of the antenna array with 4 rows and 4 columns can be considered as a small aperture, and the aperture of the two-dimensional antenna array with M rows and N columns is a large aperture.

[0155] Furthermore, in the embodiment of the present application, whether the antenna array is "sparse" or "dense" is used to characterize the arrangement of the antenna elements of the antenna array. The boundary condition between the dense arrangement and the sparse arrangement of the antenna array is usually determined by the wavelength of the antenna array and the element spacing. Specifically, when the element spacing is less than or equal to When the array element spacing is greater than When λ is greater than λ, the antenna array is considered to be sparsely arranged. In some scenarios, it can also be considered to be sparsely arranged when the average spacing between array elements is greater than λ.

[0156] In the embodiment of the present application, "sparse" and "dense" can also refer to relative concepts, which are defined by the relative size of the array element spacing between different antenna arrays. As shown in Figure 3, the antenna array 1 includes 7 rows and 7 columns of array elements, and the array element spacing is Antenna array 2 is formed by selecting the elements "●" in the 1st, 3rd, 5th, and 7th columns of the 1st, 3rd, and 5th rows of antenna array 1. In this case, antenna array 2 is considered to include elements in 3 rows and 5 columns, and the element spacing is twice the element spacing of antenna array 1, that is, λ. Therefore, the element arrangement of antenna array 2 can be considered sparse relative to the element arrangement of antenna array 1, while the element arrangement of antenna array 1 is dense relative to the element arrangement of antenna array 2. Therefore, antenna array 1 can be called a dense antenna array, and antenna array 2 can be called a sparse antenna array. Furthermore, considering the aperture sizes of antenna arrays 1 and 2, antenna array 1 can be called a large-aperture dense antenna array, and antenna array 2 can be called a small-aperture sparse antenna array.

[0157] In an ISAC system, the number of antennas in a Massive MIMO antenna array can reach 32×32 (256), meaning there are 16 antennas arranged in a single direction. These antennas can be used not only for communication but also for sensing. If the antenna resources used for sensing and communication are not clearly defined, when sensing and communication are performed simultaneously, the antennas used for sensing may not necessarily transmit CSI-RS signals. If the receiving end uses CSI-RS as a reference signal for measurement, this will result in erroneous channel measurements, leading to precoding failures and, in turn, impacting communication functionality.

[0158] In sensing applications, the antenna used for sensing is generally required to be The spacing of the array elements is arranged with a large aperture dense antenna array for sensing, which ensures that the resolution and grating lobe level of the sensing reach a good level. As shown in Figure 4, (a) in Figure 4 is the array element spacing of An 8×8 antenna array is used, in which all elements are used for perception. Taking a drone as an example, a perception signal is sent through the antenna array. The perception information obtained by measuring the echo signal of the perception signal after the perception target is affected by the perception signal is shown in (b) of Figure 4. The complex response of the signal (i.e., the amplitude-angle response image) is obtained by measuring and calculating the echo signal. By comparing the amplitude of the signal with the threshold, it can be determined whether the perception target exists. If it exists, the size, location characteristics, etc. of the perception target can be further determined based on the amplitude and angle.

[0159] However, Spacing is optional; antennas can be sparsely arranged based on the characteristics and scope of the observation area. Using a dense array for sensing without selecting antenna ports for specific application scenarios will waste antenna resources.

[0160] Therefore, how to allocate antenna resources for communication and perception has become an urgent problem to be solved. To this end, the embodiments of the present application provide an antenna resource allocation method that can implement the allocation of antenna resources for communication and perception, thereby reducing the mutual interference between communication and perception, and reducing the waste of antenna resources caused by perception.

[0161] In order to better understand the embodiments of the present application, the following explanations are made before introducing the embodiments of the present application.

[0162] First, in the embodiments of the present application, "used to indicate" can include being used for direct indication and being used for indirect indication. When describing a certain "indication information" as being used to indicate A, it can include the indication information directly indicating A or indirectly indicating A, and does not necessarily mean that the indication information carries A.

[0163] The information indicated by the indication information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, it is also possible to use the arrangement order of each piece of information agreed in advance (such as specified in the protocol) to achieve the indication of specific information, thereby reducing the indication overhead to a certain extent. At the same time, it is also possible to identify the common parts of each piece of information and indicate them uniformly to reduce the indication overhead caused by indicating the same information separately.

[0164] In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can be referred to the prior art and will not be repeated herein. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, there may be a situation where the indication methods for different information are different. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

[0165] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be predefined, for example, predefined according to the protocol, or configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of radio resource control (RRC) signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC-control element (CE); physical (PHY) layer signaling, for example, includes downlink control information (DCI).

[0166] Second, in the embodiments of the present application, the first, second, and various numerical numbers are merely distinctions made for ease of description and are not intended to limit the scope of the embodiments of the present application. For example, different indication information is used to distinguish one from another. For another example, the first indication information and the second indication information are merely used to distinguish different areas and do not limit their order of precedence. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and order of execution, and words such as "first" and "second" do not necessarily limit them to be different.

[0167] Third, in the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that the device (such as a terminal device or a network device) will make corresponding processing under certain objective circumstances. It does not limit the time, and does not require the device (such as a terminal device or a network device) to perform a judgment action when implementing it, nor does it mean that there are other limitations.

[0168] At the same time, in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner to facilitate understanding.

[0169] Finally, the network architecture and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0170] For example, Figure 5 is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. The communication system shown in Figure 5 includes a first communication device and a second communication device. The first communication device and the second communication device can perceive the perception target through a perception signal, and can also communicate wirelessly through a communication signal. The first communication device or the second communication device can implement antenna resource allocation for perception and communication based on the following method embodiments. The specific implementation process can be found in the following method embodiments and will not be described in detail here.

[0171] As another example, Figure 6 is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. The communication system includes a first communication device, a second communication device, and a third communication device. Unlike the communication system shown in Figure 5, the third communication device, as a computing node or control node, can implement antenna resource allocation for sensing and communication with the first communication device or the second communication device based on the following method embodiments. The specific implementation process can be found in the following method embodiments and is not described in detail here.

[0172] In an embodiment of the present application, each communication device, such as a first communication device, a second communication device, and a third communication device, may be configured with multiple antennas, which may include at least one transmitting antenna for sending signals and at least one receiving antenna for receiving signals. In addition, each communication device also additionally includes a transmitter chain and a receiver chain. Those skilled in the art will understand that they may include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, demodulators, demultiplexers, or antennas, etc.). Therefore, communication devices can communicate with each other through multi-antenna technology. Specifically, the communication device is provided with an antenna array, and the antenna elements in the antenna array can be used for sensing as well as for communication. In other words, the antenna array of the communication device has sensing and communication functions.

[0173] In the embodiments of the present application, a communication device having perception and communication functions may be referred to as a perception device, a perception device, a perception communication device, a perception device, a perception communication device, etc., without limitation thereto.

[0174] In a perception scenario, the first communication device may send a perception signal and the second communication device may receive an echo signal that has been acted upon by a perception target, or the second communication device may send a perception signal and the first communication device may receive an echo signal that has been acted upon by a perception target, without limitation. In the following method embodiment, an example is given in which the first communication device sends a perception signal and the second communication device receives an echo signal. Specifically, the first communication device sends a perception signal so that the second communication device can measure the echo signal to obtain perception information. The perception information can characterize attribute information of the perception target, such as information such as the speed, distance, position, shape, and size of the perception target, thereby achieving perception of the perception target. In the following method embodiment, the antenna array elements used for perception and the antenna array elements used for communication in the antenna array can be determined by selecting the antenna array elements for sending the perception signal by the first communication device or the antenna array elements for receiving the echo signal by the second communication device, so as to reduce the waste of antenna resources caused by perception.

[0175] It should be understood that in the embodiment of the present application, the number of array elements in a single direction of the antenna array of the communication device performing sensing selection is greater than or equal to 2. In other words, the number of array elements in a single direction of the antenna array of the communication device is greater than or equal to 2, that is, the array element selection can be used for sensing.

[0176] That is to say, the system shown in Figure 5 or Figure 6 includes a wireless communication system and a wireless sensing system, which can realize both wireless communication functions and wireless sensing functions. It can be understood that the communication signal and the sensing signal are relative. For example, the communication signal is a physical downlink shared channel (PDSCH).

The sensing signal is also called a detection signal, a radar signal, a radar sensing signal, a radar detection signal, an environmental sensing signal, etc. The sensing signal in the embodiment of the present application can be a signal or a physical channel. For example, the sensing signal can be a radar signal, a pulse signal, etc., such as a stepped frequency continuous waveform (SFCW) signal, a frequency modulated continuous waveform (FMCW) signal, a linear frequency modulated (LFM) signal, etc., or it can be a possible signal in a wireless communication system, such as a sounding reference signal (SRS), a demodulation reference signal (DMRS), a CSI-RS, or an OFDM signal, etc. The perception signal can also be a physical channel, such as PDSCH, physical downlink control channel (PDCCH), PUSCH, PUCCH, physical random access channel (PRACH), physical sidelink shared channel (PSSCH) or physical sidelink control channel (PSCCH).

For example, the scenario shown in Figure 5 or Figure 6 may also include more perception devices. In addition, the wireless communication system and the wireless perception system are designed as an integrated whole, so that the surrounding environment can be perceived while communicating. The system in which the wireless communication system and the wireless perception system are designed as an integrated whole is also called an integrated synaesthesia system. It should be understood that Figure 5 or Figure 6 is only a simplified schematic diagram for ease of understanding, and the communication system may also include other network devices and / or other terminal devices, which are not drawn in Figure 5 or Figure 6.

[0186] It should be noted that the solutions in the embodiments of the present application can also be applied to other communication systems, and the corresponding names can also be replaced by the names of corresponding functions in other communication systems.

[0187] The antenna resource allocation method provided in the embodiment of the present application will be described in detail below with reference to Figures 7 to 16.

[0188] For example, Figure 7 is a flowchart illustrating an antenna resource allocation method provided in an embodiment of the present application. This antenna resource allocation method is described using a first device as an example execution subject. The first device may be the first communication device, the second communication device, or the third communication device shown in Figures 5 or 6. Of course, the subject executing the actions of the first device in this method may also be a device / module within the first device, such as a chip, processor, or processing unit within the first device.

[0189] S701. The first device obtains perception information of the first perception.

[0190] The perception information of the first perception is used to indicate the area where the perception target is located. In the embodiment of the present application, the first perception can be understood as a single perception of the perception target, and the perception information of the first perception is the perception information obtained by a single perception of the perception target. The perception information of the first perception is obtained by measuring and calculating the perception signal sent during the first perception (referred to as the first perception perception signal) and the signal (referred to as the first echo signal) affected by the perception target. The perception information of the first perception can roughly feedback the location range of the perception target.

[0191] For example, the first perception information includes Q binary groups {σ q ,τ q}, q=1,2,…,Q, Q is an integer greater than 1, where σ q is the amplitude value of the response signal, which is used to characterize the complex image response of the perceived target and can feedback the shape, size and other characteristics of the perceived target. qThe response signal is the angle value of the response signal, which is used to represent the relative angle of the perceived target and can provide feedback on the area (position range) where the perceived target is located. The response signal is obtained by processing the first echo signal. Q binary groups can form the amplitude-angle response image shown in Figure 4(b). That is, the response signal is the amplitude-angle response shown in Figure 4(b). It should be understood that the angle value of the perceived target is generally a relative angle value to represent the relative position of the perceived target.

[0192] In the embodiment of the present application, the first perception may also be referred to as primary perception, or coarse perception, etc., and the second perception may also be referred to as secondary perception, secondary perception, re-perception, or fine perception, etc., without limitation thereto. In some possible situations, the first perception may be understood as the first perception, initial perception, or first perception, and the second perception may be understood as the second perception. In addition, the perception information may also be referred to as the perception result, measurement information, measurement result, or perception measurement result, etc., which may be equivalent to the imaging result in radar detection, without limitation thereto. It should be understood that the primary perception process includes two processes: sending a perception signal and measuring an echo signal to calculate the perception information. In the embodiment of the present application, the device for sending the perception signal is different from the device for receiving the echo signal, and the perception information is measured and calculated by the device for receiving the echo signal.

[0193] The following description will be made by taking as an example an apparatus for sending a perception signal the first communication apparatus in FIG. 5 or FIG. 6 , and an apparatus for receiving an echo signal the second communication apparatus in FIG. 5 or FIG. 6 .

[0194] In one possible design solution 1, the first device can locally obtain the perception information of the first perception. In this case, the first device can be a device that receives the echo signal, that is, a second communication device. In this design solution, the second communication device receives the first echo signal and determines the perception information of the first perception based on the first echo signal.

[0195] In an embodiment of the present application, the second communication device may process the received first echo signal by digital beam forming (DBF) technology, fast Fourier transform (FFT) algorithm, or back propagation (BP) algorithm to obtain the perception information of the first perception, without limitation. Exemplarily, the response signal of the first perception calculated by the DBF method can be expressed as: x1 = A1(α)*y1, wherein x1 is the response signal of the first perception, indicating the signal response corresponding to different angles within the perception area of ​​the first perception, A1(α) is the steering vector matrix corresponding to the first perception, α is the signal incidence angle or the signal transmission angle, and y1 is the received first echo signal. Based on x1, the perception information of the first perception can be determined.

[0196] In a possible design solution 2, the first device can receive the perception information of the first perception. In other words, the first device needs to obtain the perception information of the first perception from a device that calculates the perception information of the first perception, and the device that calculates the perception information of the first perception is the device that receives the echo signal (i.e., the second communication device).

[0197] In this design, in one possible scenario 1, the first device may be the device that sends the perception signal, i.e., the first communication device. In this case, after sending the first perception signal, the first communication device may receive the first perception information from the second communication device. In this case, the first perception information is obtained by measuring the received first echo signal by the second communication device. In other words, after the first communication device sends the first perception signal, the second communication device measures and calculates the first perception information based on the first echo signal and sends the first perception information to the first communication device.

[0198] In another possible scenario 2, the first device may be a device other than the device that sends the perception signal and the device that receives the echo signal, such as the third communication device in Figure 6, acting as a control node to execute S702 below. In this design, after the second communication device (the device that receives the echo signal) determines the first perception information based on the first echo signal, it may send the first perception information to the third communication device. In other words, the third communication device receives the first perception information from the second communication device.

[0199] For Scenario 1 under Design Scheme 1 and Design Scheme 2 above, in one possible implementation, the first device is a device deployed with a first antenna array, that is, the first device is a device that needs to sense and allocate communications (perception antenna selection) to antenna elements in the antenna array. The first antenna array can refer to an antenna array including at least two antenna elements in a single direction. For example, the first antenna array includes M×N antenna elements, such as the antenna array shown in (b) of Figure 2. In this case, the first device can determine the antenna elements occupied by the first perception from the first antenna array. The antenna elements occupied by the first perception constitute a second antenna array with an aperture of a second aperture, and the second aperture is smaller than the aperture of the first antenna array. Therefore, using an antenna array with a smaller aperture for the first perception can preliminarily estimate the area, shape, size, and other characteristics of the perceived target.

[0200] In Design Scheme 1, the first device is the second communication device, the first antenna array serves as the receiving array, and the first device can use the second antenna array to receive the first echo signal. That is, when receiving the first echo signal, the first device can use some of the antenna elements in the first antenna array to receive the first echo signal, and the aperture of the antenna array formed by the antenna elements receiving the first echo signal is smaller than the aperture of the first antenna array, that is, the antenna elements occupied by the first perception are the antenna elements receiving the echo signal. In this case, there is no restriction on the antenna configuration of the device sending the perception signal (the first communication device). The device sending the perception signal can be a single-antenna device or a multi-antenna device.

[0201] Among them, the antenna array elements occupied by the first perception can be locally configured by the second communication device, or configured by the first communication device to the second communication device, or configured by a control node (such as a third communication device) to the second communication device, or determined by negotiation between the first communication device and the second communication device, and there is no limitation on this.

[0202] For example, referring to (a) in FIG8 , the first antenna array includes 8×8 antenna elements, that is, M=N=8, the antenna elements are arranged at equal intervals, and the element interval is d. The aperture of the first antenna array can be expressed as 7d×7d=47d 2 , the first device can select antenna array elements in columns 3 to 6 in rows 2 to 5 from the first antenna array as antenna array elements occupied by the first perception, that is, the second antenna array elements include 4×4 antenna array elements, and the second aperture can be expressed as 3d×3d=9d 2 <47d 2 , thereby sending a first sensed sensing signal based on the second antenna array element. In this example, the first antenna array and the second antenna array have the same element spacing, but the aperture of the second antenna array is smaller than the aperture of the first antenna array.

[0203] In scenario 1 of design solution 2, the first device is the first communication device, the first antenna array serves as a transmitting array, and the first device can use the second antenna array to send the first perceived perception signal. That is to say, when the first device sends the first perceived perception signal, it can use part of the antenna elements in the first antenna array to send the first perceived perception signal, and the aperture of the antenna array formed by the antenna elements that send the first perceived perception signal is smaller than the aperture of the first antenna array, that is, the antenna elements occupied by the first perception are the antenna elements that send the perception signal. The specific implementation process can be found in the above example and will not be elaborated on. At this time, there is no restriction on the antenna configuration for the device that receives the echo signal (the second communication device), and the device that receives the echo signal can be a single-antenna device or a multi-antenna device.

[0204] Among them, the antenna array element occupied by the first perception can be configured by the second communication device to the first communication device, or can be configured by the control node (such as the third communication device) to the first communication device, or can be determined by negotiation between the first communication device and the second communication device, and there is no limitation on this.

[0205] In another possible implementation, the first device is not a device deployed with a first antenna array. In design scheme 1, the first antenna array is deployed on a device that sends a perception signal. In this case, there is no restriction on the antenna of the first device that receives the echo signal; in situation 1 of design scheme 2, the first antenna array is deployed on a device that receives the echo signal. In this case, there is no restriction on the antenna of the first device that sends the first perception perception signal.

[0206] It should be understood that in situation 2 of design scheme 2, when the device for sending perception signals or the device for receiving echo signals is deployed with a first antenna array, when sending the perception signal of the first perception or receiving the first echo signal, it can still select the second antenna array (including the antenna array elements occupied by the first perception) from the first antenna array to perform the first perception. For the specific implementation process, please refer to the relevant description in situation 1 of the above-mentioned design scheme 1 and design scheme 2, and no further details will be given.

[0207] S702. The first device determines first information based on the perception information of the first perception.

[0208] After obtaining the first perception information, the first device determines first information based on the first perception information. The first information includes a target array pattern and a scaling factor. The target array pattern and scaling factor are used to determine the antenna array elements occupied by the second perception. In other words, the first information can be used to determine the antenna array elements occupied by the second perception.

[0209] Among them, the second perception is a secondary perception of the perception target, and the antenna array element occupied by the second perception is the antenna array element used to send the second perception perception signal or to receive the second echo signal when the second perception of the perception target is performed. The second echo signal is a signal of the second perception perception signal after passing through the perception target. In this embodiment of the present application, the antenna array element occupied by the second perception is an antenna array element in the first antenna array having an aperture of the first aperture, and the first aperture is less than or equal to the aperture of the first antenna array (or the aperture of the first antenna array is greater than or equal to the first aperture).

[0210] When the second antenna array in the first antenna array (including the antenna elements used for the first perception) is used for the first perception, the first aperture is larger than the second aperture. In other words, the aperture of the antenna array formed by the antenna elements used for the second perception is larger than the aperture of the antenna array formed by the antenna elements used for the first perception. Having a larger array aperture for the second perception than for the first perception can improve perception accuracy and resolution, resulting in more accurate perception results.

[0211] For example, referring to (b) in FIG8 , the antenna array elements occupied by the second perception are located in the 1st, 3rd, 5th, and 7th columns of the 1st, 3rd, 5th, and 7th rows in the first antenna array, forming a third antenna array element. The third antenna array element includes antenna array elements in 4 rows and 4 columns, and the array element spacing is 2d. The first aperture can be expressed as 6d×6d=36d. 2 , 9d 2 <36d 2 <47d 2 .

[0212] An array pattern, as the name implies, is a pattern or structure formed by a set of elements or graphics arranged according to a certain regular pattern. Based on this pattern or structure, an antenna array can be mapped. In the embodiments of the present application, the elements in the array pattern can be arranged uniformly or non-uniformly. It should be understood that an element in the array pattern can be equivalent to an antenna element, and the distance between two adjacent elements in the array pattern can be equivalent to the element spacing.

[0213] For a possible example, please refer to Figure 9, which is a structural schematic diagram of an array pattern provided in an embodiment of the present application. (a) in Figure 9 shows an evenly arranged array pattern, in which the elements “■” in the array pattern are distributed in a 4×4 square, and each adjacent “■” is separated by a “□”.

[0214] For an array pattern, the following parameters may be included: the central wavelength (expressed as λ) of the antenna in the antenna array mapped by the array pattern i ), the average element spacing of the antenna array mapped by the array pattern (expressed as d i , which can be understood as the spacing between two adjacent elements in the array pattern) and the array factor of the antenna array mapped by the array pattern (expressed as AF i The array factor determines the gain and phase characteristics of the antenna array in different directions. By adjusting the array factor, functions such as signal directionality, beamforming, and spatial filtering can be achieved. The size of the array factor depends on the geometric structure of the antenna array mapped by the array pattern, the array element spacing, and the weight settings.

[0215] The center wavelength of the antenna in the antenna array mapped by the array pattern and the average element spacing of the antenna array mapped by the array pattern can be obtained by the first parameter k i express, Used to indicate the electrical size of the element spacing of the antenna array mapped by the array pattern.

[0216] In one possible implementation, for a uniform linear array (ULA) pattern, the array factor can be expressed as:

[0217] Among them, AF i (α) Array factor, α is the signal incident angle or signal transmission angle, w(n) is the weight of the zth element in the array pattern, 1≤z≤Z, z and Z are integers, Z is the total number of elements in the array pattern, d i is the distance between two adjacent elements in the array pattern, v i is the wave number, v i =2π / λ i .

[0218] If the weights of all elements in the array pattern are the same, that is, w(z)=w, then Where α0 is the phase shift function of the elements in the array pattern.

[0219] For non-uniform linear array patterns, as shown in Figure 9(b), the non-uniformity of the spacing and position between elements in the array pattern needs to be considered. The array factor can be expressed as:

[0220] in, is the phase of the zth element in the array pattern, and r(z) is the position of the zth element in the array pattern.

[0221] It should be understood that for different array patterns, λ i d i , AF i At least one of (α) is different.

[0222] The target array pattern is used to determine the number and relative positions of the antenna elements occupied by the second perception. The relative position can be the position of the antenna elements occupied by the second perception determined based on the position of the antenna elements in the antenna array mapped by the target array pattern, which can be understood as the position of the antenna elements occupied by the second perception relative to the antenna elements in the antenna array mapped by the target array pattern. In an embodiment of the present application, the target array pattern can be determined based on the first angle range and the spatial resolution, and the first angle range is determined based on the perception information of the first perception. That is to say, after performing the first perception on the perception target, the first device can determine the first angle range based on the perception information of the first perception, and determine the target array pattern based on the first angle range and the spatial resolution.

[0223] It should be understood that the determination of the antenna elements occupied by the second sensing is related to the aperture parameters of the first antenna array (such as the number of antenna elements and element spacing). In other words, after determining the first angular range and spatial resolution, the first device combines the aperture parameters of the first antenna array to determine the target array pattern. If the first device is not equipped with the first antenna array, the aperture parameters of the first antenna array can be sent to the first device by the device equipped with the first antenna array.

[0224] Among them, the specific meaning of the first angle range is related to the location where the first antenna array is deployed. The first angle range is used to feedback the angle range of the perception target relative to the device that sends the perception signal or the device that receives the echo signal, and can be used as the beam scanning range for sending the perception signal or receiving the echo signal during the second perception. If the first antenna array is deployed on the first communication device (the device that sends the perception signal), the first angle range is the angle range in which the first communication device sends the perception signal for the second perception; if the first antenna array is deployed on the second communication device (the device that receives the echo signal), the first angle range is the angle range in which the second communication device receives the second echo signal. That is to say, in an embodiment of the present application, the first angle range can not only be used to determine the antenna array element occupied by the second perception, but also can be used to instruct the first communication device to use the antenna array element occupied by the second perception to send the second perception signal, or to instruct the second communication device to use the antenna array element occupied by the second perception to receive the second echo signal. The beam scanning angle range ensures that the first communication device or the second communication device accurately perceives the position of the perception target. It should be understood that the first angle range can be understood as the scanning range of sending or receiving signals during the second perception. In the embodiment of the present application, the scanning of sending perception signals or receiving echo signals during the first perception can be in the form of 180° scanning.

[0225] Spatial resolution refers to the size of the smallest detail or smallest feature that can be distinguished in an image, map or other spatial data. It is used to characterize the spatial resolution capability of the system, that is, the system can distinguish the minimum distance between two adjacent objects or details. It is usually expressed in unit length (such as meter-m) or angle unit (such as degree-°), indicating that details can be distinguished at this length and angle. A higher spatial resolution means that smaller details can be distinguished, while a lower spatial resolution means that only larger features can be distinguished. In an embodiment of the present application, the spatial resolution is expressed as δ, and the spatial resolution can be pre-agreed or pre-configured. For example, if the first device is a first communication device, the spatial resolution can be configured to the first communication device by the second communication device, or it can be configured to the first communication device by a control node (such as a third communication device), or it can be determined by negotiation between the first communication device and the second communication device, and there is no limitation on this.

[0226] Correspondingly, the first device can also determine the second angle range based on the perception information of the first perception. When the first angle range is the angle range in which the first communication device sends the perception signal of the second perception, the second angle range is the angle range in which the second communication device receives the second echo signal; when the first angle range is the angle range in which the second communication device receives the second echo signal, the second angle range is the angle range in which the first communication device sends the perception signal of the second perception.

[0227] Exemplarily, the first perceived perceptual information includes Q binary groups {σ q ,τ q}, for each {σ q ,τ q}, the first device will σ q Compare with the set threshold value t (such as t = 0.1), and set σ1 to σ Q All |σ greater than t q |(modulus value) corresponding to τ q Angle range A τ =[τ min ,τ max ], τ min σ1~σ Q All |σ greater than t q |The corresponding τ q The minimum angle value in τ max σ1~σ Q All |σ greater than t q The corresponding τ q The maximum angle value in , and according to the transformation relationship between the global coordinate system and the coordinate system with the device sending the perception signal (the first communication device) and the device receiving the echo signal (the second communication device) as the center origin, A τThe angle range of the sensing target relative to the first communication device is obtained by mapping, that is, the angle range for sending the sensing signal of the second sensing, which is expressed as A T ={θ T,min ,θ T,max}, and the angular range of the sensing target relative to the second communication device, that is, the angular range for receiving the second echo signal, is expressed as A R ={θ R,min ,θ R,max}.

[0228] In one possible implementation, the target array pattern may be determined from an array pattern set according to the first angular range and spatial resolution. The array patterns in the array pattern set may be predefined or preconfigured by a protocol, each array pattern in the array pattern set may correspond to an identifier or index, and each array pattern may correspond to the above-mentioned parameter λ. i d i , AF i (α), different array patterns can represent different antenna arrays. After the target array pattern is determined, the target array pattern can be indicated by sending an identifier or index of the target array pattern.

[0229] In an embodiment of the present application, the scaling factor can be determined based on the first angle range and the first parameter of the target array pattern. The first parameter of the target array pattern represents the electrical size of the array element spacing of the antenna array mapped by the target array pattern, and can be used to characterize the relative position of the antenna array element occupied by the second perception.

[0230] In one possible implementation, the scaling factor may be determined based on the maximum element spacing that can be set for the antenna elements occupied by the second sensing, the operating wavelength of the antenna in the first antenna array, and the first parameter of the target array pattern, where the maximum element spacing is determined based on the first angle range. Exemplarily, the scaling factor may satisfy the following relationship: Where S is the scaling factor, d max is the maximum element spacing, λ is the operating wavelength of the antenna in the first antenna array, k p is the first parameter of the target array pattern.

[0231] In one possible scenario, It can be expressed as k0 to indicate the maximum electrical size of the array element spacing that can be set for the antenna array elements occupied by the second perception. At this time, At this time, the scaling factor can be considered as the ratio of the electrical size of the array element spacing of the antenna array mapped by the target array pattern to the maximum electrical size of the array element spacing of the antenna array composed of the antenna array elements occupied by the second perception. In another possible situation, due to The scaling factor can also be expressed as

[0232] In one possible implementation, the maximum element spacing may be determined based on a maximum sine value and an operating wavelength of an antenna in the first antenna array, where the maximum sine value is the maximum absolute value of the sine values ​​calculated based on the angle values ​​in the first angle range. Exemplarily, the maximum element spacing may satisfy the following relationship: where |sinθ| max is the maximum sine value.

[0233] In another possible implementation, the maximum element spacing can be determined based on the length of the first angular range and the operating wavelength of the antennas in the first antenna array. For example, the maximum element spacing can satisfy the following relationship: Wherein, A is the length of the first angle range. If the first angle range is the angle range A of the first communication device sending the second sensing signal T ={θ T,min ,θ T,max}, then A=θ T,max -θ T,min If the first angle range is the angle range A at which the second communication device receives the second echo signal R ={θ R,min ,θ R,max}, then A=θ R,max -θ R,min .

[0234] It should be understood that the maximum element spacing in the embodiment of the present application is determined to ensure that there is no ambiguity (i.e., no grating lobe) in the perception within the first angle range, and the element spacing of the antenna elements occupied by the second perception needs to satisfy d≤d max .

[0235] For example, the first device may determine the first angle range according to the first sensed perception information, and then determine the maximum array element interval d according to the first angle range. max , and determine the target antenna array from the array pattern set in combination with the spatial resolution δ and the operating wavelength λ of the antennas in the first antenna array, such as selecting an array pattern from the array pattern set that satisfies the following conditions as the target array pattern: Among them, d i is the average element spacing of the antenna array mapped by the array pattern, λ i is the central wavelength of the antenna in the antenna array mapped by the array pattern, δ i is the resolution capability of the antenna array mapped by the array pattern, δ i Array factor AF according to the array pattern i (α), that is, δ i Support AF i(α) 3 decibel (dB) width of the main lobe.

[0236] If there are multiple array patterns that meet the above conditions, the array pattern with the least elements is selected as the target array pattern, that is, the array pattern with the least number of array elements in the mapped antenna array is selected as the target array pattern. If the target array pattern is the array pattern shown in (a) of Figure 9, the central wavelength of the antenna in the antenna array mapped by the target array pattern is expressed as λ p , the average element spacing of the antenna array mapped by the target array pattern is expressed as d p , the array factor is expressed as AF p (α), the first parameter of the target array pattern is expressed as

[0237] After determining the target array pattern, the first device can further determine a scaling factor based on the target array pattern. The scaling factor is used to determine the element spacing of the antenna elements occupied by the second perception. After determining the target array pattern, the element spacing of the antenna array mapped by the target array pattern can be scaled using the scaling factor to determine the element spacing of the antenna elements occupied by the second perception. In other words, the antenna array mapped by the target array pattern is different from the antenna array composed of the antenna elements occupied by the second perception. It can be considered that the antenna array composed of the antenna elements occupied by the second perception is obtained by scaling the antenna array mapped by the target array pattern using the scaling factor.

[0238] For example, the target array pattern d p Multiplying by the scaling factor S forms a new array pattern, and the antenna array mapped by the new array pattern is the antenna array occupied by the second perception. That is, the number of antenna elements occupied by the second perception is the same as the number of elements in the target array pattern (or the same as the number of elements in the antenna array mapped by the target antenna array), and the average element spacing of the antenna array occupied by the second perception is S times the average element spacing of the antenna array mapped by the target array pattern, that is, d p ×S.

[0239] In one possible design, the first device may determine the antenna elements occupied by the second perception in the first antenna array based on the determined target array pattern and scaling factor, and use the antenna elements occupied by the second perception to send the perception signal of the second perception or to receive the second echo signal. In this design, the first device needs to perform perception and communication allocation on the antenna elements in its own deployed antenna array. The first device may be a first communication device (a device that sends the perception signal) deployed with the first antenna array, or the first device may be a second communication device (a device that receives the echo signal) deployed with the first antenna array.

[0240] Furthermore, the first device may use the antenna array element occupied by the second perception to send the perception signal of the second perception within the first angle range or to receive the second echo signal.

[0241] Under this design, in one possible implementation, the first device may further transmit third information, where the third information is used to indicate the second angular range. If the first device is a first communication device (a device that transmits a perception signal) deployed with a first antenna array, the first communication device transmits the third information to the second communication device, and the second communication device accordingly receives the third information from the first communication device. In this case, the second angular range is the angular range within which the second communication device receives the second echo signal. If the first device is a second communication device (a device that receives an echo signal) deployed with a first antenna array, the second communication device transmits the third information to the first communication device, and the first communication device accordingly receives the third information from the second communication device. In this case, the second angular range is the angular range within which the first communication device transmits the second perception signal.

[0242] When the first communication device and the second communication device are both access network devices, the third information can be sent through the Xn interface; when the first communication device and the second communication device are both terminal devices, the third information can be sent through the sidelink (SL), such as the third information is carried in the sidelink control information (SCI); when one of the first communication device and the second communication device is a terminal device and the other is an access network device, the third information can be carried in signaling such as RRC, MAC-CE or DCI and sent.

[0243] In another possible design, the first device may send the first information. In this case, the first device does not need to sense and allocate communications to antenna elements in its own deployed antenna array. The first device may be a first communication device (a device that sends the perception signal) that is not deployed with the first antenna array, or a second communication device (a device that receives the echo signal) that is not deployed with the first antenna array, or a third communication device that only serves as a control node to determine the first information.

[0244] In the case where the first device is a first communication device, the first communication device can send first information to the second communication device, and accordingly, the second communication device receives the first information from the first communication device, so that the second communication device can determine the antenna array elements occupied by the second perception in the first antenna array according to the target array pattern and scaling factor in the first information. In the case where the first communication device sends the perception signal of the second perception, the second communication device uses the antenna array elements occupied by the second perception to receive the second echo signal, and determines the perception information of the second perception based on the second echo signal.

[0245] In this scenario, the first angular range is the angular range within which the second communication device receives the second echo signal, and the second angular range is the angular range within which the first communication device transmits the second perception signal. Furthermore, the first communication device may transmit second information to the second communication device, the second information being used to indicate the first angular range. Thus, the first communication device may transmit the second perception signal within the second angular range, and the second communication device may correspondingly receive the second echo signal within the first angular range using the antenna array elements occupied by the second perception signal.

[0246] In the case where the first device is the second communication device, the second communication device can send first information to the first communication device, and accordingly, the first communication device receives the first information from the second communication device, so that the first communication device can determine the antenna array elements occupied by the second perception in the first antenna array according to the target array pattern and scaling factor in the first information, and use the antenna array elements occupied by the second perception to send the perception signal of the second perception.

[0247] In this scenario, the first angular range is the angular range within which the first communication device transmits the second sensing signal, and the second angular range is the angular range within which the second communication device receives the second echo signal. Furthermore, the second communication device can send second information to the first communication device, the second information being used to indicate the first angular range. Thus, the first communication device can use the antenna array elements occupied by the second sensing signal to transmit the second sensing signal within the first angular range, and the second communication device can correspondingly receive the second echo signal within the second angular range.

[0248] In the case where the first device is a third communication device, if the first communication device is deployed with a first antenna array, the first angle range is the angle range in which the first communication device sends the perception signal of the second perception, and the second angle range is the angle range in which the second communication device receives the second echo signal, then the third communication device sends the first information to the first communication device, and accordingly, the first communication device receives the first information from the third communication device, so that the first communication device can determine the antenna array element occupied by the second perception in the first antenna array according to the target array pattern and scaling factor in the first information.

[0249] Furthermore, the third communication device may send second information to the first communication device, the second information being used to indicate the first angular range, and the third communication device may send third information to the second communication device, the third information being used to indicate the second angular range. This allows the first communication device to transmit a second sensing signal within the first angular range using the antenna array elements occupied by the second sensing device, and allows the second communication device to receive a second echo signal within the second angular range.

[0250] If the second communication device is deployed with a first antenna array, the first angle range is the angle range in which the second communication device receives the second echo signal, and the second angle range is the angle range in which the first communication device sends the perception signal of the second perception, then the third communication device sends the first information to the second communication device, and accordingly, the second communication device receives the first information from the third communication device, so that the second communication device can determine the antenna array element occupied by the second perception in the first antenna array based on the target array pattern and scaling factor in the first information.

[0251] Furthermore, the third communication device may send second information to the second communication device, the second information being used to indicate the first angular range, and the third communication device may send third information to the first communication device, the third information being used to indicate the second angular range. This enables the first communication device to send a perception signal for the second perception within the first angular range, and enables the second communication device to receive a second echo signal within the second angular range using the antenna array element occupied by the second perception.

[0252] In this design, the first information and the second information can optionally be carried in the same message. Based on different application scenarios, the first information, the second information, and the third information are sent in different ways. For details, please refer to the relevant description of the carrying method of the third information in the above design, which will not be repeated here.

[0253] In an embodiment of the present application, antenna elements in the first antenna array other than the antenna elements occupied by the second sensing are used for communication, and the communication device can use the first antenna array to perform sensing and communication simultaneously.

[0254] Based on the antenna resource allocation method shown in FIG7 , a phased sensing method (e.g., first sensing and second sensing) is employed. A first device can determine first information based on sensing information from the first sensing. The first information includes a target array pattern and scaling factor for determining the antenna elements occupied by the second sensing. This allows a sensing device (e.g., a device transmitting a sensing signal or a device receiving an echo signal) to allocate antenna resources for sensing and communication based on the first information to perform the second sensing. This reduces interference between sensing and communication, improves antenna resource utilization, and enhances the accuracy of the second sensing.

[0255] For example, FIG10 is a flow chart of another antenna resource allocation method provided in an embodiment of the present application. The antenna resource allocation method is described by taking the second device as the execution subject as an example. The second device can be the first communication device or the second communication device shown in FIG5 or FIG6. Of course, the subject that executes the action of the second device in this method can also be a device / module in the second device, such as a chip, processor, processing unit, etc. in the second device. As shown in FIG10, the antenna resource allocation method includes the following steps:

[0256] S1001. The second device obtains first information.

[0257] Among them, the first information includes a target array pattern and a scaling factor, and the target array pattern and the scaling factor are used to determine the antenna array elements occupied by the second perception. It should be understood that in the embodiment of the present application, the second device is a device that is deployed with a first antenna array in a perception communication scenario and can allocate antenna array elements in the first antenna array for perception and communication based on the first information. In other words, the second device can determine which antenna array elements in the first antenna array are used for perception and which antenna array elements are used for communication based on the first information. Exemplarily, the second device can be a device that sends a perception signal, hereinafter referred to as a first communication device, or a device that receives an echo signal, hereinafter referred to as a second communication device.

[0258] In one possible design, the second device can locally obtain the first information. In this case, the second device can be equivalent to the first device in Figure 7 above. The second device can determine the first information based on the obtained perception information of the first perception. The perception information of the first perception can be obtained locally, in which case the second device is the second communication device, or it can be sent to the second device by the second communication device, in which case the second device is the first communication device.

[0259] In this design, the second device can also locally obtain the first angular range and the second angular range. If the second device is a first communication device, the first angular range is the angular range within which the first communication device transmits the second perception signal, and the second angular range is the angular range within which the second communication device receives the second echo signal. In this case, the first communication device can also send third information to the second communication device, the third information being used to indicate the second angular range, so that the second communication device can receive the second echo signal within the second angular range.

[0260] When the second device is a second communication device, the first angular range is the angular range within which the second communication device receives the second echo signal, and the second angular range is the angular range within which the first communication device transmits the second perceived perception signal. In this case, the second communication device may further transmit third information to the first communication device, the third information being used to indicate the second angular range, so that the first communication device can transmit the second perceived perception signal within the first angular range.

[0261] In another possible design, the second device may receive the first information from the first device in FIG. 7 . In this case, the first device may be a first communication device, a second communication device, or a third communication device. If the first device is the first communication device or the third communication device, the second device is the second communication device; if the first device is the second communication device or the third communication device, the second device is the first communication device.

[0262] In this design, the second device can receive second information indicating a first angular range. If the second device is a first communication device, the first communication device can receive the second information from the first communication device or a third communication device. In this case, the first angular range is the angular range within which the first communication device transmits a second perception signal, and the second perception signal can be transmitted within the first angular range. If the second device is a second communication device, the second communication device can receive the second information from the first communication device or a third communication device. In this case, the first angular range is the angular range within which the second communication device receives a second echo signal, and the second echo signal can be received within the first angular range.

[0263] The specific implementation process can be found in the relevant descriptions in S701 and S702 above, and will not be described in detail here.

[0264] S1002. The second device uses the antenna array element occupied by the second perception to send a second perception signal, or the second device uses the antenna array element occupied by the second perception to receive a second echo signal.

[0265] After the second device obtains the first information, it can determine the antenna array elements occupied by the second perception in the first antenna array based on the target array pattern and scaling factor in the first information, and use the antenna array elements occupied by the second perception to send the second perception signal, or use the antenna array elements occupied by the second perception to receive the second echo signal. The antenna array elements occupied by the second perception are shown in (b) of Figure 8, and the antenna array elements occupied by the second perception constitute a third antenna array.

[0266] For example, the target array pattern is the array pattern shown in (a) of FIG9 , and the average element spacing of the antenna array mapped by the target array pattern is d p , the scaling factor is S, the second device can be used to change the target array pattern d p Multiplying by the scaling factor S forms a new array pattern, and the antenna array mapped by the new array pattern is the antenna array occupied by the second perception. That is, the number of antenna elements occupied by the second perception is the same as the number of elements in the target array pattern (or the same as the number of elements in the antenna array mapped by the target antenna array), and the average element spacing of the antenna array occupied by the second perception is S times the average element spacing of the antenna array mapped by the target array pattern, that is, d p ×S.

[0267] When the second device receives the second echo signal using the antenna array element occupied by the second perception, the second device may further determine perception information of the second perception based on the second echo signal. The process of determining the perception information of the second perception is similar to that of determining the perception information of the first perception, and reference may be made to the relevant description in S701 above, which is not repeated here.

[0268] For the specific description of the antenna array elements occupied by the second perception, please refer to the relevant description in the above S702, which will not be repeated here.

[0269] Based on the antenna resource allocation method shown in Figure 10, the second device can determine which antenna elements in its deployed antenna array are used for perception and which antenna elements are used for communication based on the target array pattern and scaling factor in the acquired first information, thereby realizing the allocation of antenna resources for perception and communication, reducing interference between perception and communication, and improving the utilization rate of antenna resources.

[0270] The following describes in detail the methods shown in FIG. 7 and FIG. 10 in conjunction with specific application scenarios.

[0271] Scenario 1: The first communication device acts as the second device, and the second communication device acts as the first device, which can be applicable to communication and perception between access network devices, between access network devices and terminal devices, or between terminal devices.

[0272] For example, FIG11 is a flow chart of an antenna resource allocation method provided in an embodiment of the present application. As shown in FIG11 , the antenna resource allocation method includes the following steps:

[0273] S1100: A first communication device sends aperture parameters of a first antenna array to a second communication device. Correspondingly, the second communication device receives the aperture parameters of the first antenna array from the first communication device.

[0274] The aperture parameters of the first antenna array include the number of antenna elements and the element spacing, etc. The aperture parameters can be used by the second communication device to perform the following S1103 to determine the first information. It should be understood that S1103 may be an optional step.

[0275] S1101: A first communication device transmits a first sensing signal using a second antenna array, and a second communication device receives a first echo signal.

[0276] The second antenna array is an antenna array with a second aperture, smaller than the aperture of the first antenna array, within the first antenna array deployed on the first communication device. The second antenna array includes antenna elements occupied by the first sensing element. The first echo signal is a signal of the first sensing element after being acted upon by the sensing target. The specific implementation of S1101 can be found in the relevant description of S701 above and is not further described here.

[0277] S1102. The second communication device determines first perceived perception information based on the first echo signal.

[0278] The first sensed perception information is used to indicate the area where the sensed target is located. The specific implementation process of S1102 can refer to the relevant description in S701 above, and will not be repeated here.

[0279] S1103. The second communication device determines the first information based on the perception information of the first perception.

[0280] The first information includes the target array pattern and the scaling factor. The specific implementation process of S1103 can refer to the relevant description in S702 above, which will not be repeated here.

[0281] During the determination of the first information, the second communication device may determine a first angle range and a second angle range based on the first sensed perception information. The first angle range is the angle range within which the first communication device transmits the second sensed perception signal, and the second angle range is the angle range within which the second communication device receives the second echo signal.

[0282] S1104: The second communication device sends the first information to the first communication device. Correspondingly, the first communication device receives the first information from the second communication device.

[0283] When the first communication device and the second communication device are both access network devices, the first information can be sent through the Xn interface; when the first communication device and the second communication device are both terminal devices, the first information can be sent through the side link, such as the first information is carried in the SCI; when one of the first communication device and the second communication device is a terminal device and the other is an access network device, the first information can be carried in signaling such as RRC, MAC-CE or DCI and sent.

[0284] S1105: The second communication device sends second information to the first communication device. Correspondingly, the first communication device receives the second information from the second communication device.

[0285] The second information indicates the first angular range. The first communication device may determine a transmit beam scanning range for the perceived target based on the first angular range and transmit a second perceived sensing signal within the first angular range, thereby improving the accuracy of the sensing. It should be understood that step S1105 may be optional. Furthermore, the present embodiment does not limit the order in which S1104 and S1105 are performed.

[0286] Optionally, the first information and the second information may be carried in the same message and sent.

[0287] S1106. The first communication device determines the antenna array element occupied by the second perception based on the first information.

[0288] The antenna array elements occupied by the second sensing are antenna array elements in the first antenna array having a first aperture, and the first aperture is less than or equal to the aperture of the first antenna array and greater than the second aperture. The specific implementation process of S1106 can be found in the relevant description of S702 or S1002 above and is not repeated here.

[0289] S1107: The first communication device transmits a second sensing signal using the antenna array elements occupied by the second sensing. Correspondingly, the second communication device receives the second echo signal.

[0290] The second echo signal is a signal obtained by applying the second sensing signal to the sensing target. It should be understood that the first communication device can use antenna elements in the first antenna array other than the antenna elements occupied by the second sensing element for communication.

[0291] Optionally, the first communication device uses the antenna array element occupied by the second perception to send the second perception signal within the first angle range, and correspondingly, the second communication device receives the second echo signal within the second angle range.

[0292] S1108. The second communication device determines second perceived perception information based on the second echo signal.

[0293] Among them, since the aperture of the antenna array used for the second perception is larger than the aperture of the antenna array used for the first perception, the larger the antenna array aperture, the higher the perception resolution and accuracy. Therefore, the perception resolution and accuracy of the perception information of the second perception are higher than the perception resolution and accuracy of the first perception. In the embodiment of the present application, the process of determining the perception information of the second perception can refer to the process of determining the perception information of the first perception, and will not be repeated here.

[0294] The above Figure 11 shows a scenario in which the second communication device calculates the first information based on the perception information of the first perception to instruct the first communication device to determine the antenna array elements used for the second perception, so as to realize the perception and communication antenna resource allocation on the first communication device side.

[0295] Scenario 2: The first communication device serves as both the first device and the second device, and can be applicable to communication and perception between access network devices, between an access network device and a terminal device, or between terminal devices.

[0296] For example, FIG12 is a flow chart of an antenna resource allocation method provided in an embodiment of the present application. As shown in FIG12 , the antenna resource allocation method includes the following steps:

[0297] S1201: A first communication device transmits a first sensing signal using a second antenna array, and a second communication device receives a first echo signal.

[0298] The specific implementation process of S1201 can refer to the relevant description in the above S701 or S1101, which will not be repeated here.

[0299] S1202. The second communication device determines first perceived perception information based on the first echo signal.

[0300] The specific implementation process of S1202 can refer to the relevant description of S701 or S1102 above, which will not be repeated here.

[0301] S1203: The second communication device sends the first-perceived perception information to the first communication device. Correspondingly, the first communication device receives the first-perceived perception information from the second communication device.

[0302] When the first communication device and the second communication device are both access network devices, the perception information of the first perception can be sent through the Xn interface; when the first communication device and the second communication device are both terminal devices, the perception information of the first perception can be sent through the side link, such as the perception information of the first perception is carried in the SCI and sent; when one of the first communication device and the second communication device is a terminal device and the other is an access network device, the perception information of the first perception can be carried in signaling such as RRC, MAC-CE or DCI and sent.

[0303] S1204. The first communication device determines first information based on the first perceived perception information.

[0304] The specific implementation process of S1204 can refer to the relevant description in the above S702 or S1103, which will not be repeated here.

[0305] During the determination of the first information, the second communication device may determine a first angle range and a second angle range based on the first sensed perception information. The first angle range is the angle range within which the first communication device transmits the second sensed perception signal, and the second angle range is the angle range within which the second communication device receives the second echo signal.

[0306] S1205: The first communication device sends third information to the second communication device. Correspondingly, the second communication device receives the third information from the first communication device.

[0307] The third information is used to indicate the second angular range, so that the second communication device can determine the receive beam scanning range for the perceived target based on the second angular range and receive the second echo signal within the second angular range, thereby improving perception accuracy. It should be understood that the embodiment of the present application does not limit the execution order of S1204 and S1205, and S1205 is an optional step.

[0308] S1206. The first communication device determines the antenna array elements occupied by the second perception based on the first information.

[0309] S1207: The first communication device transmits a second sensing signal using the antenna array elements occupied by the second sensing. Correspondingly, the second communication device receives the second echo signal.

[0310] S1208. The second communication device determines second perceived perception information based on the second echo signal.

[0311] The specific implementation process of S1206 to S1208 can be found in the relevant descriptions in the above S1106 to S1108, which will not be repeated here.

[0312] In the scenario shown in Figure 12 above, the first communication device calculates the first information based on the perception information of the first perception sent by the second communication device, and determines the antenna array elements occupied by the second perception based on the first information to realize the allocation of antenna resources for perception and communication on the side of the first communication device.

[0313] In scenarios 1 and 2, there is no limitation on the antenna mode of the second communication device for receiving the echo signal. The second communication device may be a single-antenna receiving device or a multi-antenna receiving device.

[0314] Scenario 3: The second communication device serves as both the first device and the second device, and can be applicable to communication and perception between access network devices, between access network devices and terminal devices, or between terminal devices.

[0315] For example, FIG13 is a flow chart of an antenna resource allocation method provided in an embodiment of the present application. As shown in FIG13 , the antenna resource allocation method includes the following steps:

[0316] S1301: A first communication device sends a first sensing signal. Correspondingly, a second communication device receives a first echo signal using a second antenna array.

[0317] The first echo signal is a signal obtained by affecting the first sensing target. The specific implementation process of S1301 can refer to the relevant description of S701, S1101 or S1201 above, and will not be repeated here.

[0318] S1302. The second communication device determines first perceived perception information based on the first echo signal.

[0325] S1305: The second communication device sends third information to the first communication device. Correspondingly, the first communication device receives the third information from the second communication device.

[0326] The third information is used to indicate the second angle range. It should be understood that the embodiment of the present application does not limit the execution order of S1304 and S1305, and S1305 is an optional step.

[0327] S1306: The first communication device sends a second sensing signal. Correspondingly, the second communication device receives a second echo signal using the antenna array elements occupied by the second sensing.

[0328] S1307. The second communication device determines second perceived perception information based on the second echo signal.

[0329] The specific implementation process of S1306 and S1307 can refer to the relevant description in the above S1106 to S1108 or S1206 to S1208, which will not be repeated here.

[0330] In the scenario shown in Figure 13, the second communication device calculates the first information based on the perception information of the first perception, so as to determine the antenna array element used for the second perception based on the first information, so as to realize the allocation of antenna resources for perception and communication on the side of the second communication device.

[0331] Scenario 4: The first communication device serves as the first device, and the second communication device serves as the second device, which can be applicable to communication and perception between access network devices, between access network devices and terminal devices, or between terminal devices.

[0332] For example, FIG14 is a flow chart of an antenna resource allocation method provided in an embodiment of the present application. As shown in FIG14 , the antenna resource allocation method includes the following steps:

[0374] The following is a brief description of the technical effects achieved by the technical solution provided in the embodiment of the present application in conjunction with Figures 4 and 16.

[0375] Taking the second device as an example of a device that sends a perception signal, (a) in Figure 16 is the process of the first perception. The first antenna array includes 8×8 antenna array elements, and the array element spacing is d=2 / λ. The first perception uses an antenna array in the first antenna array that includes 4×4 antenna array elements and the array element spacing is 2 / λ (that is, the second antenna array, including the antenna array elements occupied by the first perception) to send the first perception perception signal. The perception result of the first perception perception information feedback obtained by measuring and calculating the first echo signal generated by the perception signal of the first perception through the perception target is relatively rough. (b) in FIG16 shows a process of determining the antenna elements occupied by the second perception for performing the second perception based on the perception information of the first perception. The second perception uses an antenna array in the first antenna array with an element spacing of 2d=λ and including 4×4 antenna elements (i.e., a third antenna array, including the antenna elements occupied by the second perception) to send a perception signal for the second perception. The perception result of the second perception perception information feedback obtained by measuring and calculating the second echo signal generated by the perception target based on the second perception perception signal is more accurate than the perception result of the first perception perception information feedback, and is basically consistent with the perception result obtained by using all antenna elements in the first antenna array to send the perception signal as shown in FIG4 . That is, the perception resolution and peak to sidelobe ratio (PSLR) are guaranteed not to change, but the antenna resources used for perception are reduced.

[0376] It can be understood that in the above embodiments, the methods and / or steps implemented by the first device can also be implemented by components that can be used for the first device (such as a processor, chip, chip system, circuit, logic module, or software); the methods and / or steps implemented by the second device can also be implemented by components that can be used for the second device (such as a processor, chip, chip system, circuit, logic module, or software).
