[0004] FIG. 1 is a structural diagram of an intelligent surface according to the related art. As shown in FIG. 1, each adjustable electromagnetic unit needs to correspond to a group of electrical control devices. FIG. 2 is a schematic diagram of the implementation of phase characteristic adjustment control according to the related art. As shown in FIG. 2, a control chip is connected to each electromagnetic unit via a bus. Assuming there are N adjustable electromagnetic units, each electromagnetic unit needs to have an internal electrical control device connected to the control chip via a bus. The control chip adjusts and controls the phase of each electromagnetic unit according to the needs of actual applications.

[0005] When the number of intelligent surface elements or controllable electromagnetic units is very large, there are some major technical problems. 1. To achieve better results in a real scenario, the number of electromagnetic units that need to be controlled and adjusted, N, must be greater than 10. 3 ~10 5If the matrix needs to be as large as this, the calculation of the N-dimensional adjustment control matrix corresponding to the electromagnetic characteristics will become very large and complex, which is disadvantageous for the application of intelligent surfaces. 2. Different users, different transmission or reflection policies, and different channels or signals have different performance and electromagnetic coverage needs, and the adjustment control policy cannot flexibly adjust and control as needed to accommodate these differences, making it inefficient. 3. The contribution of different electromagnetic units to overall performance varies, and in related technologies, there are cases where the contribution of some electromagnetic units to performance is low but high-precision adjustment control is still required, resulting in unnecessary waste of calculation volume and waste of control signaling overhead.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0013] On the one hand, intelligent surfaces can intelligently control the channel environment, providing greater transmission capacity, higher wireless charging efficiency, and stronger robustness. On the other hand, they can support access for ultra-large-scale terminals, thereby enabling the most ambitious vision of realizing the IoT. The intelligent surfaces described herein can actually be deployed in wireless environments with active physical surface electromagnetic fields, each part of which can transmit and receive electromagnetic fields. Intelligently controlling these electromagnetic fields can concentrate energy transmission and reception in a three-dimensional space, potentially improving capacity efficiency and reducing interference. These surfaces therefore bring new electromagnetic environment communication, sensing, and control capabilities. Intelligent surfaces can be used in a variety of areas, including solving high-frequency non-line-of-sight transmission problems, resolving coverage holes, reducing electromagnetic pollution, passive IoE, low-cost large-scale transmission and reception, and increasing channel spatial freedom.

[0014] The basic principle of intelligent surfaces is to generate adjustable radiation fields by modifying the electromagnetic properties of intelligent surface elements (IS elements), also known as adjustable electromagnetic units, to obtain the desired radiation characteristics and achieve massive multiple-input multiple-output (MIMO) beamforming effects during transmission or reflection. In theory, the electromagnetic properties that can be modified include phase, amplitude, frequency, polarization, and angular momentum. Intelligent surfaces have the ability to modify electromagnetic properties, allowing electromagnetic waves to be controlled according to user expectations, opening up a wide range of potential applications.

[0015] FIG. 3 is a schematic diagram illustrating the implementation of a controllable electromagnetic unit according to an embodiment of the present application. The intelligent surface includes a plurality of controllable electromagnetic units. As shown in FIG. 3, the controllable electromagnetic units may be simple electronic component structures (e.g., diodes, transistors, capacitors, resistors, etc.), or may be of various media or pore sizes. FIG. 3 lists several simple methods for implementing the controllable electromagnetic units. In practice, there are numerous ways to implement the electromagnetic units, and they are not limited to the following few methods. The controllable electromagnetic units in the intelligent surface are attached to a dielectric substrate, and the controllable electromagnetic units can emit, reflect, and transmit electromagnetic waves.

[0016] 4 is a flowchart of an electromagnetic unit adjustment control method according to an embodiment of the present application, which is implemented by an intelligent surface. As shown in FIG. 4, this embodiment includes steps S110 to S140.

[0017] In S110, a set of electromagnetic units waiting for regulation control S2, which is a subset of the set of electromagnetic units that can be regulated S1, is determined.

[0018] In one embodiment, the set of electromagnetic units waiting for adjustment control S2 refers to all electromagnetic units in the intelligent surface that need to be adjusted, and the set of adjustable electromagnetic units S1 refers to all electromagnetic units in the intelligent surface whose electromagnetic properties can be adjusted. In one embodiment, the number of all electromagnetic units included in the set of electromagnetic units waiting for adjustment control S2 must be less than or equal to all electromagnetic units in the intelligent surface, i.e., less than or equal to the number of all electromagnetic units in the set of adjustable electromagnetic units S1.

[0019] In S120, the electromagnetic unit set is divided into groups to obtain X electromagnetic unit groups.

[0020] In an embodiment, X is a positive integer greater than or equal to 1. In an embodiment, the electromagnetic unit set includes one of an electromagnetic unit set S2 waiting for adjustment control and an electromagnetic unit set S1 that can be adjusted. In an embodiment, the electromagnetic unit set S2 waiting for adjustment control can be grouped to obtain X electromagnetic unit groups. In an embodiment, all electromagnetic units on the intelligent surface can be grouped, i.e., the electromagnetic unit set S1 that can be adjusted can be grouped to obtain X electromagnetic unit groups.

[0021] In S130, a set of electromagnetic characteristics waiting for adjustment control is determined.

[0022] In an embodiment, the electromagnetic characteristic set waiting for adjustment control refers to one or more electromagnetic characteristics in the electromagnetic characteristic set that all the electromagnetic units in the electromagnetic unit set waiting for adjustment control need to adjust. In an embodiment, all the electromagnetic units in the electromagnetic unit set waiting for adjustment control may adjust one electromagnetic characteristic in the electromagnetic characteristic set, or may adjust multiple electromagnetic characteristics in the electromagnetic characteristic set.

[0023] In S140, the adjustment control of at least one electromagnetic property in the electromagnetic property set is performed for the electromagnetic unit set S2 waiting for adjustment control based on the electromagnetic unit group.

[0024] In an embodiment, each electromagnetic unit group can adjust one or more electromagnetic properties in the electromagnetic property set. The electromagnetic properties adjusted by all electromagnetic units in the same electromagnetic unit group are the same. For example, after grouping the electromagnetic units, electromagnetic unit group A and electromagnetic unit group B are obtained, and electromagnetic unit group A and electromagnetic unit group B also belong to the electromagnetic unit set waiting for adjustment control. The electromagnetic properties of electromagnetic unit group A and electromagnetic unit group B can be adjusted, respectively. Here, the electromagnetic properties adjusted by electromagnetic unit group A and electromagnetic unit group B can be the same or different, and there is no limitation thereto. They can be set according to user needs, and the electromagnetic properties adjusted by the same group are the same, or the accuracy of adjustment control is the same.

[0025] In an embodiment, before performing adjustment control of the electromagnetic properties of the electromagnetic units, the electromagnetic unit sets are grouped based on different conditions, and the number of electromagnetic units waiting for adjustment control is less than or equal to the total number of electromagnetic units on the intelligent surface, and the number of electromagnetic units waiting for adjustment control is greater than or equal to 1, so that the electromagnetic units waiting for adjustment control have more purpose, improve the efficiency of adjustment control, reduce the dimension of adjustment control, and reduce the complexity of adjustment control.

[0026] In the embodiment, the order of execution of S110 to S130 is not limited. In one embodiment, S110, S120, and S130 can be executed sequentially, that is, after determining the set of electromagnetic units waiting for adjustment control, all the electromagnetic units in the set of electromagnetic units waiting for adjustment control are grouped to obtain an electromagnetic unit group, and then adjustment control of one or more electromagnetic properties in the preset electromagnetic property set is performed for the electromagnetic unit group. In the embodiment, if S120 is executed after S110, the electromagnetic units to be grouped belong to all the electromagnetic units in the set of electromagnetic units waiting for adjustment control.

[0027] In one embodiment, S120, S110 and S130 can be executed sequentially, that is, all electromagnetic units on the intelligent surface are grouped to obtain at least two electromagnetic unit groups, and then a predetermined number of electromagnetic unit groups are selected from the at least two electromagnetic unit groups as a set of electromagnetic units waiting for adjustment control, and based on the electromagnetic unit groups, adjustment control of one or more electromagnetic properties in the electromagnetic property set is performed on the electromagnetic units in the set of electromagnetic units waiting for adjustment control. In an embodiment, if S110 is executed after S120, the electromagnetic units to be grouped belong to all the electromagnetic units on the intelligent surface.

[0028] In the above embodiment, S130 may be executed before S110 and S120, or may be executed after S120 and S120, but is not limited thereto, as long as it is executed before S130 and S140.

[0029] In one embodiment, determining the set of electromagnetic units waiting to be adjusted and controlled includes determining the set of electromagnetic units waiting to be adjusted and controlled based on a first preset condition, or determining that the set of electromagnetic units waiting to be adjusted and controlled S2 is equal to the set of electromagnetic units that can be adjusted and controlled S1.

[0030] In one embodiment, the first preset condition includes a preset condition based on an operating frequency of wireless communication, a preset condition based on a received power at an intelligent surface, a preset condition based on a channel or signal type, a preset condition based on a target user of downlink transmission, a preset condition based on a target access point of uplink transmission, a preset condition based on a communication link type, a preset condition based on content of control signaling transmitted from an access point (AP) or a user equipment (UE), a preset condition based on a type of electromagnetic characteristics to be controlled, a preset condition based on accuracy of adjustment control of electromagnetic characteristics, a preset condition based on granularity of adjustment control of electromagnetic characteristics, and a modulation and coding scheme. the preset condition is based on the number of transmission layers to be multiplexed; the preset condition is based on the antenna setting of the transmitting side or the receiving side; the preset condition is based on the transmission power of the AP or the UE; and the preset condition is based on the transmission precoding or the transmission beam of the AP or the UE.

[0031] In one embodiment, the operating frequency of wireless communication includes an operating frequency of transmission, reflection or transmission, and the high or low operating frequency of wireless communication is proportional to the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control.

[0032] In one embodiment, when the first preset condition is the received power at the intelligent surface, determining a set of electromagnetic units waiting for adjustment control based on the first preset condition includes determining a comparison result between the received power at a single electromagnetic unit or multiple electromagnetic units at the intelligent surface and a preset power threshold, and when the received power at the single electromagnetic unit or multiple electromagnetic units is greater than or equal to the power threshold, adding the single electromagnetic unit or multiple electromagnetic units to the set of electromagnetic units waiting for adjustment control.

[0033] In one embodiment, the method of determining the power threshold includes one of the following: a fixed value, a base station setting, a UE setting, or an implicit determination based on target parameters, wherein the target parameters include one or more of the operating frequency of wireless communication, permittivity, conductivity, permeability, number of electromagnetic units, number of multiplexed transmission layers, type of electromagnetic characteristics to be adjusted, IS application, MCS method, communication link type, channel or signal type, AP or UE transmission power, and AP or UE transmission precoding or transmission beam.

[0034] In one embodiment, the type of channel or signal includes one of a shared control channel, a broadcast channel, a data channel, a synchronization signal, and a pilot signal.

[0035] In one embodiment, when the type of the channel or signal is a shared control channel, a broadcast channel, or a synchronization signal, the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control is greater than the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control when the type of the channel or signal is a data channel or a pilot signal.

[0036] In one embodiment, the pilot signal includes a measurement pilot and a demodulation pilot, and the number of electromagnetic unit data included in the set of electromagnetic units waiting for adjustment control corresponding to the measurement pilot is greater than the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control corresponding to the demodulation pilot.

[0037] In one embodiment, when the first preset condition is a target user of downlink transmission, determining the set of electromagnetic units waiting for adjustment control based on the first preset condition includes: determining the set of electromagnetic units waiting for adjustment control based on the location of the target user of downlink transmission, or determining the set of electromagnetic units waiting for adjustment control based on the number of target users of downlink transmission, or determining the set of electromagnetic units waiting for adjustment control based on an identifier (ID) of the target user of downlink transmission.

[0038] In one embodiment, when the first preset condition is a target access point for upstream transmission, determining a set of electromagnetic units awaiting adjustment control based on the first preset condition includes determining a set of electromagnetic units awaiting adjustment control based on the position of the target access point for upstream transmission, or determining a set of electromagnetic units awaiting adjustment control based on the number of target access points for upstream transmission, or determining a set of electromagnetic units awaiting adjustment control based on the ID of the target access point for upstream transmission.

[0039] In one embodiment, the type of communication link includes one of a downlink from an AP to a UE, an uplink from a UE to an AP, a sidelink between UEs, and a backhaul link between APs.

[0040] In one embodiment, the order of the modulation and decoding scheme is proportional to the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control.

[0041] In one embodiment, the magnitude of the dielectric constant is inversely proportional to the number of electromagnetic units included in the set of electromagnetic units waiting for regulation control.

[0042] In one embodiment, the characteristics of the set of electromagnetic units waiting for adjustment control include at least one of being arranged in a rectangular, circular, or annular shape, the number of electromagnetic units in the horizontal dimension being greater than the number of electromagnetic units in the vertical dimension, and the density of the electromagnetic units being non-uniform. In one embodiment, the non-uniform density of the electromagnetic units means that the density of the electromagnetic units is denser in the center and sparser towards the outside.

[0043] FIG. 5 is a schematic diagram illustrating the relationship between the set of electromagnetic units to be adjusted and all electromagnetic units in an intelligent surface according to the present application. As shown in FIG. 5, all electromagnetic units in the intelligent surface are denoted as S1, and the set of electromagnetic units to be adjusted is denoted as S2. In the related art, the set of electromagnetic units to be adjusted S2 is the total set S1 of all available, controllable electromagnetic units in the intelligent surface, i.e., the electromagnetic units included in S1 and S2 are the same. In the present embodiment, the set of electromagnetic units to be adjusted S2 is selected from the total set of controllable electromagnetic units in the intelligent surface to suit the current transmission or reflection needs, i.e., S2 is a subset of S1. Selecting S2 from S1 can take into account multiple factors, and the set of electromagnetic units to be adjusted S2 can be determined based on a first preset condition. Determining S2 may include, but is not limited to, the number of electromagnetic units included in S2, the pitch of the electromagnetic units included in S2, the density of the electromagnetic units included in S2, and the distribution pattern of the electromagnetic units included in S2.

[0044] In one embodiment, the electromagnetic unit set S2 waiting for adjustment control is determined based on a first preset condition, which may include one or more combinations of a preset condition based on an operating frequency of wireless communication, a preset condition based on a received power at an intelligent surface, a preset condition based on a channel or signal type, a preset condition based on a target user for downlink transmission, a preset condition based on a target access point for uplink transmission, a preset condition based on a communication link type, a preset condition based on content of control signaling transmitted from an AP or a UE, a preset condition based on a type of electromagnetic characteristics waiting for control, a preset condition based on the accuracy of adjustment control of the electromagnetic characteristics, a preset condition based on the granularity of adjustment control of the electromagnetic characteristics, a preset condition based on an MCS scheme, a preset condition based on permittivity, conductivity, or permeability, a preset condition based on the application of an IS, a preset condition based on the number of multiplexed transmission layers, a preset condition based on an antenna setting on a transmitting side or a receiving side, and a preset condition based on the transmission power, transmission precoding, or transmission beam of an AP or a UE.

[0045] In one embodiment, when the first preset condition is based on the operating frequency of wireless communication, the selected electromagnetic control-ready unit set S2 may have different electromagnetic units at different operating frequencies, for example, 30 GHz and 100 GHz. In one embodiment, the operating frequency of wireless communication includes the operating frequency of transmission, reflection, or transmission. In one embodiment, the higher the operating frequency of wireless communication, the larger the selected control-ready electromagnetic unit set (i.e., the more electromagnetic units it includes). In actual operation, coverage defects exist at high frequencies, and more intelligent surface elements can be used to compensate for this defect. In one embodiment, the size of the S2 set can be determined based on the operating frequency of wireless communication, for example, S2 sets corresponding to different frequency values ​​can be predetermined.

[0046] In one embodiment, when the first preset condition is based on the received power at the intelligent surface, the received power at an electromagnetic unit or multiple electromagnetic units (which may be a group of electromagnetic units) can be used to determine whether the electromagnetic unit or multiple electromagnetic units should be added to the set of electromagnetic units awaiting adjustment control. If the received power of an electromagnetic unit or multiple electromagnetic units is very low, it is considered that its contribution to transmission is small, i.e., that no adjustment control will affect transmission performance. In one embodiment, a power threshold can be set to determine the S2 set. If the received power at a single electromagnetic unit or multiple electromagnetic units is less than the power threshold, the electromagnetic unit or multiple electromagnetic units will not be selected by the S2 set. If the received power at a single electromagnetic unit or multiple electromagnetic units is equal to or greater than the power threshold, the electromagnetic unit or multiple electromagnetic units can be selected by the S2 set. In one embodiment, the power threshold can be set to a fixed value or a non-fixed value. For example, the power threshold may be set by a base station or a terminal, or may be implicitly determined based on the setting of other types of parameters, such as the wireless communication operating frequency, channel or signal type, target transmitting user or target transmitting AP, communication link type, electromagnetic characteristic type, electromagnetic characteristic adjustment control precision, electromagnetic characteristic adjustment control granularity, modulation coding method, permittivity, and intelligent surface application. When these parameters differ, the corresponding power threshold setting may differ. Furthermore, because the transmission policy of an AP or UE affects the received power at an IS, the S2 set may be determined by the setting of parameters such as the transmission power and precoding weight value of the AP or UE. Different transmission powers and precoding weight values ​​of the AP or UE may correspond to the selection of different S2 sets.

[0047] In one embodiment, if the first preset condition is based on the channel or signal type, different channel or signal types may correspond to different sets of electromagnetic units awaiting adjustment control. For example, a shared control channel, a broadcast channel, a data channel, a synchronization signal, and a pilot signal may all correspond to different S2 sets. The intelligent surface IS acquires channel or signal type information, and the IS determines the S2 set based on the channel or signal type information. In an embodiment, the shared control channel, the broadcast channel, and the synchronization signal are intended for multiple users, and a larger number of electromagnetic units may be selected, and the distribution must be sufficiently wide. The data channel and pilot signal are intended for one specific terminal or a small number of terminals, and a portion of electromagnetic units relatively close to the target user may be selected to form an S2 set for transmission, transmission through, or reflection, and the number of electromagnetic units may be small. In an embodiment, the pilot signal may be divided into measurement pilots and demodulation pilots. Measurement pilots require a larger number of electromagnetic units in the S2 set than demodulation pilots. In an embodiment, the determination of the S2 set needs to be based on the type and characteristics of the channel or signal, so as to better adapt to the transmission of the channel. In one embodiment, the S2 sets may be determined based on the content of the transmission, for example, different signaling or data, or the importance of the signaling or data.

[0048] In one embodiment, if the first preset condition is based on the location of the target user of downlink transmission, the intelligent surface can be used for transmissions of different users. In one embodiment, if the size of the intelligent surface is large, the distances from different users to the electromagnetic units on the intelligent surface will be different, and the concentration areas of electromagnetic units that have the greatest effect on transmissions for users at different locations will be different. That is, the S2 set can be determined based on the location of the target user of downlink transmission. In one embodiment, the distance between the UE and the IS at different locations will also be different. The greater the distance, the larger the S2 set that needs to be selected. In one embodiment, during the wireless communication transmission process, one user or multiple users may be served. In one embodiment, FIG. 6 is a schematic diagram illustrating the relationship between the location of the target user and the set of electromagnetic units waiting for adjustment control according to an embodiment of the present application. As shown in FIG. 6, terminal A and terminal B each correspond to one set of electromagnetic units waiting for adjustment control, where the distance between terminal B and the IS is closer than the distance between terminal A and the IS, that is, the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control corresponding to terminal A is larger.

[0049] In one embodiment, the first preset condition is based on the number of target users of downlink transmission. In this embodiment, the number of target users of downlink transmission is different, and the corresponding S2 set selection is different. That is, the S2 set can be determined based on the number of target users of the service. Figure 7 is a schematic diagram of the relationship between the number of target users and the set of electromagnetic units waiting for adjustment control according to an embodiment of the present application. As shown in Figure 7, the number of target users of the service in the upper diagram includes three users, namely, terminal A, terminal B, and terminal C, and the number of target users of the service in the lower diagram includes one user, namely, terminal A. That is, the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control with three target users is greater than the number of electromagnetic units included in the set of electromagnetic units waiting for adjustment control with one target user.

[0050] In one embodiment, the first preset condition is based on the location of the target AP for upstream transmission. The intelligent surface can be used to transmit and reflect signals to different target APs during upstream transmission. Because different APs have different locations, different S2 sets can be selected to transmit or reflect signals to optimize transmission performance. Figure 8 is a schematic diagram illustrating the relationship between the location of the target AP and the set of electromagnetic units waiting to be adjusted according to an embodiment of the present application. As shown in Figure 8, AP1 and AP2 each correspond to a set of electromagnetic units waiting to be adjusted. The distance between AP2 and the IS is closer than the distance between AP1 and the IS, i.e., the set of electromagnetic units waiting to be adjusted corresponding to AP1 includes a larger number of electromagnetic units.

[0051] In one embodiment, the first preset condition is based on the number of target APs for upstream transmission. In this embodiment, upstream transmission may be performed by serving a single AP for reception or by serving multiple APs for cooperative reception. Different numbers of target APs select different S2 sets; that is, S2 sets can be determined based on the number of target APs to be served. Figure 9 is a schematic diagram illustrating the relationship between the number of target APs and sets of electromagnetic units to be adjusted according to an embodiment of the present application. As shown in Figure 9, the number of target APs to be served in the upper diagram includes one access point, AP2, while the number of target APs to be served in the lower diagram includes three access points, AP1, AP2, and AP3. That is, the number of electromagnetic units included in a set of electromagnetic units to be adjusted with three target APs is greater than the number of electromagnetic units included in a set of electromagnetic units to be adjusted with one target AP.

[0052] In one embodiment, the first preset condition is based on the type of communication link. In this embodiment, the intelligent surface can be used for various types of links, such as a downlink from an AP to a UE, an uplink from a UE to an AP, a sidelink between UEs, and a backhaul link between APs. In this embodiment, different S2 sets correspond to different types of communication links, i.e., different S2 sets can be selected to transmit or reflect based on the type of communication link. In actual operation, due to limited uplink coverage, the number of electromagnetic units included in the S2 set corresponding to uplink transmission is greater than the number of electromagnetic units included in the S2 set corresponding to downlink transmission, i.e., the S2 set for downlink transmission may be a subset of the S2 set for uplink transmission.

[0053] In one embodiment, the first preset condition is based on the content of control signaling transmitted from an AP or a UE. In this embodiment, the intelligent surface determines how to select electromagnetic units from the S1 set to form the S2 set based on the received control signaling transmitted from the AP or the UE. In this embodiment, the control signaling can directly specify which electromagnetic units form the S2 set, or can be determined in conjunction with some configuration parameters (e.g., the operating frequency of wireless communication, the receiving frequency of the intelligent surface, the channel or signal type, the communication link type, etc.) described in other embodiments of this application.

[0054] In one embodiment, when the first preset condition is based on the type of electromagnetic characteristic to be controlled, the intelligent surface determines the type of electromagnetic characteristic to be controlled, and determines how to select electromagnetic units from the set S1 to form the set S2 based on the type of electromagnetic characteristic. For example, the adjustment control of the phase characteristic is performed by selecting one set S2. 2-phaseThe amplitude characteristic adjustment control corresponds to one set S 2-am The frequency characteristic adjustment control corresponds to one set S 2-rf The regulation control of the orbital angular momentum properties corresponds to one set S 2-oam The regulation control of the spin angular momentum properties corresponds to one set S 2-sam Corresponds to.

For example, the phase adjustment control of BPSK is performed by selecting one set S2. 2-bpsk , and the QPSK phase adjustment control is one set S 2-qpsk Corresponds to.

[0056] In one embodiment, the first preset condition is a preset condition based on the granularity of the adjustment control of the electromagnetic properties.

Based on the granularity, it determines how to select electromagnetic units from set S1 to form set S2. The granularity can be expressed not only by the number of electromagnetic units, but also by the area of ​​the electromagnetic units. If the control is based on the same number of electromagnetic units but different areas, the granularity will also be different. For example, the granularity of the adjustment control can be 1 cm. 2 Grain size: 0.5cm 2 Grain size: 0.25cm 2 It can be described as the granularity of

[0057] In one embodiment, the first preset condition is based on an MCS scheme. In this embodiment, different MCS schemes have different S2 set size requirements, for example, the number of electromagnetic units included in the S2 set corresponding to a higher MCS scheme is larger. In this embodiment, a higher MCS requires better transmission performance and more robust channel conditions; otherwise, large amounts of data transmission will be inaccurate and resources will be wasted. In this embodiment, the S2 set can be determined based on the MCS scheme, i.e., the higher the MCS is transmitted, the larger the number of electromagnetic units included in the S2 set.

In one embodiment, the S2 set can be determined based on conductivity and permeability, etc., i.e., different S2 sets corresponding to different conductivities are different, and different S2 sets corresponding to different permeabilities are different.

[0059] In one embodiment, the first preset condition is based on the application of the IS. In this embodiment, the application of the IS can be divided into three categories: transmission, reflection, and transmission.

When the application of the IS is reflection or transmission, this is considered a passive application, and the electromagnetic unit generates an induced current. Figure 10 is a schematic diagram illustrating the principle of different applications of the IS according to this embodiment. As shown in Figure 10, when the application of the IS is reflection or transmission, transmitting a corresponding reflected or transmitted signal from the electromagnetic metasurface is considered a passive application. In this embodiment, the transmission characteristics of these various applications are different, and the requirements for the electromagnetic unit are also different. That is, different S2 sets can be selected based on the application of the IS.
