Description

Technical Field

[0001] The following description relates to base station systems, base stations, communication auxiliary components and methods performed by the same. Background Art

[0002] Considering the development of wireless communication from generation to generation, these technologies are mainly developed for services targeting people, such as voice calls, multimedia services and data services. With the commercialization of the fifth generation (5G) communication system, the number of connected devices is expected to grow exponentially. These will be increasingly connected to the communication network. Examples of the Internet of Things can include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machinery and factory equipment. Mobile devices are expected to develop in various forms (such as augmented reality glasses, virtual reality headsets and holographic devices). Efforts have been made to develop improved 6G communication systems in order to provide various services by connecting hundreds of billions of devices and things in the sixth generation (6G) era. For these reasons, 6G communication systems are called super 5G systems.

[0003] The 6G communication system, which is expected to be commercialized around 2030, will have a peak data rate of tera (1,000 gigabits) bps and a radio latency of less than 100 μsec, thus being 50 times the data rate of the 5G communication system and having 1 / 10 of its radio latency.

[0004] In order to achieve such high data rates and ultra-low latency, the implementation of 6G communication systems in terahertz (e.g., 95GHz to 3THz bands) has been considered. It is expected that since the path loss and atmospheric absorption in the terahertz band are more serious than those in the millimeter wave (mmWave) band introduced in 5G, technologies that can ensure the signal transmission distance (i.e., coverage) will become more critical. As the main technology to ensure coverage, it is necessary to develop radio frequency (RF) elements, antennas, new waveforms with better coverage than orthogonal frequency division multiplexing (OFDM), beamforming and massive multiple input multiple output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, and multi-antenna transmission technologies such as massive antennas. In addition, new technologies for improving terahertz band signal coverage have been discussed, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable smart surfaces (RIS).

[0005] In addition, in order to improve spectrum efficiency and overall network performance, the following technologies have been developed for 6G communication systems: full-duplex technology for enabling uplink transmission and downlink transmission to use the same frequency resources at the same time; network technology that utilizes satellites, high altitude platform stations (HAPS), etc. in an integrated manner; improved network structure for supporting mobile base stations, etc., and enabling network operation optimization and automation, etc.; dynamic spectrum sharing technology via conflict avoidance based on spectrum usage prediction: using artificial intelligence (AI) in wireless communication to improve overall network operation by utilizing AI from the design stage of developing 6G and internalizing end-to-end AI support functions; and next-generation distributed computing technology that overcomes the computing power limitations of user equipment (UE) through ultra-high performance communication and computing resources (such as mobile edge computing (MEC), cloud, etc.) that can be realized on the network. In addition, attempts are continuing to strengthen connectivity between devices, optimize networks, promote softwareization of network entities, and increase openness of wireless communications by designing new protocols to be used in 6G communication systems, developing mechanisms for realizing hardware-based security environments and secure use of data, and developing technologies for maintaining privacy.

[0006] Research and development of 6G communication systems, including hyperconnectivity of human-to-machine (P2M) and machine-to-machine (M2M), are expected to bring about the next hyperconnectivity experience. In particular, services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replicas are expected to be provided through 6G communication systems. In addition, services such as remote surgery, industrial automation, and emergency response for enhanced safety and reliability will be provided through 6G communication systems, making it possible for the technology to be applied to various fields such as industry, healthcare, automobiles, and home appliances.

Different embodiments of the present disclosure may be implemented in any suitably arranged communications system.

[0055] Figure 1 An example wireless network according to an embodiment of the present disclosure is shown. Figure 1 The embodiment of the wireless network shown in FIG. 1 is for illustration only. Other embodiments of the wireless network 100 may be used without departing from the scope of the present disclosure.

[0056] like Figure 1 As shown, the wireless network includes base station (gNB or gNodeB) 101, gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one network 130 such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0057] The gNB 102 provides wireless broadband access to a network 130 for a plurality of first user equipments (UEs) within a coverage area 120 of the gNB 102. The plurality of first UEs include a UE 111 that may be located at a small business (SB); a UE 112 that may be located at an enterprise (E); a UE 113 that may be located at a WiFi hotspot (HS); a UE 114 that may be located at a first residence (R1); a UE 115 that may be located at a second residence (R2); and a UE 116 that may be a mobile device (M) such as a cellular phone, a wireless laptop, a wireless personal digital assistant (PDA), etc. The gNB 103 provides wireless broadband access to the network 130 for a plurality of second UEs within a coverage area 125 of the gNB 103. The plurality of second UEs include UE 115 and UE 116 and subscriber stations (SS, e.g., UEs) 117, 118, and 119. In some embodiments, one or more of gNBs 101 103 may communicate with each other and UE 111 116 using existing wireless communication technologies, and one or more of UE 111 119 may communicate directly with each other (e.g., UE 117 119) using other existing or proposed wireless communication technologies.

[0058] Depending on the network type, the term "base station" or "BS" may refer to any component (or collection of components) configured to provide wireless access to a network, such as a transmission point (TP), a transceiver point (TRP), an enhanced (or "evolved") base station (eNodeB or eNB), a 5G base station (gNB), a macro cell, a femto cell, a wireless fidelity (WiFi) access point (AP), or other wireless-capable device. A base station may provide wireless access according to one or more wireless communication protocols, such as 3GPP 5G New Radio (NR), Long Term Evolution (LTE), Advanced LTE (LTE A), High Speed ​​Packet Access (HSPA), Wi Fi 802.11a / b / g / n / ac, etc. For convenience, various names of base station type devices and functions are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Moreover, depending on the network type, the term "user equipment" (UE) may refer to any component such as a mobile station (MS), a subscriber station (SS), a remote terminal, a wireless terminal, a receiving point, or a user device. For convenience, various names of user equipment type devices and functions are used interchangeably in this patent document to refer to a remote wireless device that wirelessly accesses a BS, regardless of whether the UE is a mobile device (such as a mobile phone or smart phone) or a device generally considered to be a fixed device (such as a desktop computer or a vending machine).

[0059] Dashed lines illustrate the approximate extents of coverage areas 120 and 125, which are shown as generally circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with a gNB, such as coverage areas 120 and 125, may have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the wireless environment associated with natural and artificial obstacles.

[0060] As described in more detail below, one or more of the UEs 111 119 include circuitry, programming, or a combination thereof. In some embodiments, one or more of the gNBs 101 103 include circuitry, programming, or a combination thereof.

[0061] although Figure 1 An example of a wireless network is shown, but Figure 1 Various changes may be made. For example, wireless network 100 may include any number of gNBs and any number of UEs in any suitable arrangement. Moreover, gNB 101 may communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102 103 may communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. In addition, gNBs 101, 102, and / or 103 may provide access to other or additional external networks such as an external telephone network or other types of data networks.

[0062] Figure 2 An example base station according to an embodiment of the present disclosure is shown. Figure 2 The embodiments of gNB 102 shown in FIG. are for illustration only, and Figure 1 gNBs 101 and 103 may have the same or similar configurations. However, gNBs appear in a variety of configurations, and Figure 2 The scope of the present disclosure is not limited to any particular implementation of the gNB.

[0063] like Figure 2 As shown in FIG. 1 , gNB 102 includes multiple antennas 200a 200n, multiple radio frequency (RF) transceivers 201a 201n, transmit (TX) processing circuitry 203, and receive (RX) processing circuitry 204. gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface 207.

[0064] The RF transceiver 201a 201n receives incoming RF signals from the antenna 200a 200n, such as signals sent by a UE in the network 100. The RF transceiver 201a 201n down-converts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuit 204, which generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 204 sends the processed baseband signal to the controller / processor 205 for further processing.

[0065] The TX processing circuit 203 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from the controller / processor 205. The TX processing circuit 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 201a 201n receives the outgoing processed baseband or IF signal from the TX processing circuit 203 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 201a 201n.

[0066] Controller / processor 205 may include one or more processors or other processing devices that control the overall operation of gNB 102. For example, controller / processor 205 may control the reception of forward channel signals and the transmission of reverse channel signals by RF transceivers 201a 201n, RX processing circuitry 204, and TX processing circuitry 203 in accordance with well-known principles. Controller / processor 205 may also support additional functionality, such as more advanced wireless communication functionality.

[0067] For example, the controller / processor 205 may support beamforming or directional routing operations, in which outgoing signals from multiple antennas 200a-200n are weighted differently to effectively steer the outgoing signals in a desired direction. Any of a variety of other functions may be supported in the gNB 102 by the controller / processor 205.

[0068] Controller / processor 205 is also capable of executing programs and other processes, such as an operating system (OS), located in memory 206. Controller / processor 205 may move data into or out of memory 206 as required by the executing processes.

[0069] The controller / processor 205 is also connected to a backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or via a network. The interface 207 may support communication over any appropriate (one or more) wired or wireless connections. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G, LTE, or LTE A), the interface 207 may allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the interface 207 may allow the gNB 102 to communicate over a wired or wireless local area network or over a wired or wireless connection to a larger network (such as the Internet). The interface 207 includes any appropriate structure that supports communication over a wired or wireless connection such as an Ethernet or RF transceiver.

[0070] Memory 206 is connected to controller / processor 205. A portion of memory 206 may include random access memory (RAM), and another portion of memory 206 may include flash memory or other read-only memory (ROM).

[0071] although Figure 2 An example of gNB 102 is shown, but the Figure 2 For example, gNB 102 may include any number of Figure 2 As a specific example, the access point may include multiple interfaces 207, and the controller / processor 205 may support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, the gNB 102 may include multiple instances of each (such as one for each RF transceiver). For example, Figure 2 The various components in may be combined, further subdivided, or omitted, and additional components may be added according to specific needs.

[0072] Figure 3 An example user device according to an embodiment of the present disclosure is shown. Figure 3 The embodiment of UE 116 shown in FIG. 1 is for illustration only, and Figure 1 UEs 111 115 and 117 119 may have the same or similar configurations.

The memory 311 includes an OS 312 and one or more applications 313.

[0074] RF transceiver 302 receives incoming RF signals transmitted by a gNB of network 100 from antenna 301. RF transceiver 302 downconverts the incoming RF signals to generate an IF or baseband signal. The IF or baseband signal is sent to RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 305 sends the processed baseband signal to speaker 306 (such as for voice data) or processor 307 for further processing (such as for web browsing data).

[0075] The TX processing circuit 303 receives analog or digital voice data from the microphone 304 or other outgoing baseband data (such as web data, email, or interactive video game data) from the processor 307. The TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuit 303 and up-converts the baseband or IF signal to an RF signal that is transmitted via the antenna 301.

[0076] The processor 307 may include one or more processors or other processing devices and executes the OS 312 stored in the memory 311 to control the overall operation of the UE 116. For example, the processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceiver 302, the RX processing circuit 305, and the TX processing circuit 303 according to well-known principles. In some embodiments, the processor 307 includes at least one microprocessor or microcontroller.

[0077] The processor 307 is also capable of executing other processes and programs located in the memory 311, such as a process for CSI reporting on the uplink channel. The processor 307 can move data into or out of the memory 311 as needed to execute the process. In some embodiments, the processor 307 is configured to execute the application 313 based on the OS 312 or in response to a signal received from the gNB or operator. The processor 307 is also coupled to the I / O interface 309, which provides the UE 116 with the ability to connect to other devices such as laptops and portable computers. The I / O interface 309 is the communication path between these accessories and the processor 307.

[0078] Processor 307 is also connected to touch screen display 310. A user of UE 116 may use touch screen display 310 to enter data into UE 116. Touch screen display 310 may be a liquid crystal display, light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from a website.

[0079] The memory 311 is connected to the processor 307. A portion of the memory 311 may include a RAM, and another portion of the memory 311 may include a flash memory or other ROM.

[0080] although Figure 3 An example of UE 116 is shown, but the Figure 3 Make various changes. For example, Figure 3 The various components in the embodiment may be combined, further subdivided, or omitted, and additional components may be added as required. As a specific example, processor 307 may be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although Figure 3 The UE 116 is shown configured as a mobile phone or smart phone, but the UE may be configured to operate as other types of mobile or stationary devices.

[0081] With the rapid development of mobile communication technology, higher requirements are placed on the transmission rate of the network. In the deployment and development of 5G / 6G technology, the advantages of high bandwidth and high speed of high-frequency communication are obvious, but it also exposes problems such as short transmission distance, high power consumption and high cost, which are particularly prominent in high-frequency bands such as millimeter waves and THz. To a certain extent, large-scale applications are restricted, and currently only a few countries can provide services in the corresponding frequency bands.

[0082] The transmission distance of the signal is inversely proportional to the operating frequency. The same base station transmits the same distance, and the higher the frequency band, the weaker the received signal strength. Walls, trees and other materials will cause more serious signal attenuation at high frequencies, resulting in more signal blind spots. In order to meet the complete coverage of the cell with high-frequency signals, the base station transmit power can be increased or the base station construction density can be increased. The resulting equipment cost and energy consumption will increase sharply, becoming a major obstacle to large-scale commercialization.

[0083] As a kind of passive device (without high-power devices such as power amplifiers), intelligent reconfigurable antenna technology (RIS, also known as intelligent antenna, intelligent reflector antenna, intelligent metasurface, etc.) changes the electromagnetic parameters of the unit by adjusting the loading parameters to change the propagation direction of the beam. Its main power consumption comes from the power consumption of the loading parameter adjustment system (usually <2W), so it can be deployed over a large area as a low-cost, low-energy auxiliary device to provide multiple paths for signal transmission. Large-scale RIS antenna arrays can focus energy to narrow the beam width, increase signal gain, and can be used for long-distance transmission.

[0084] In addition to enhancing coverage and capacity, RIS can also provide virtual line-of-sight links, eliminate local coverage holes, serve users at the edge of cells, and solve co-channel interference between cells, thereby realizing an intelligent and reconfigurable wireless environment. According to the mechanism of action of RIS, it can be divided into transmission type, reflection type, absorption type and hybrid type, and dynamically regulate wireless signals according to the required wireless functions, such as ensuring communication network security, reducing electromagnetic pollution, supporting passive Internet of Things, enabling wireless energy transmission and auxiliary positioning perception.

[0085] Unlike the repeater in the 5G communication system, RIS has only a small amount or no signal receiving and processing hardware to meet the system's low power consumption and low cost requirements. In actual application, it is necessary to solve the problems of how to realize the control information reception of the RIS panel and the power supply of the driver board. The RIS without power amplifier devices (low power consumption) only needs to power the driver board. When deployed outdoors, it can meet the needs by adding solar panels or rechargeable batteries. The transmission of control signals can be achieved by connecting directly to the base station side through a network cable. When communicating with a RIS far away from the base station, especially when there are a large number of RIS in the community, the deployment complexity of this solution is relatively high. Hybrid RIS adds signal RF receiving devices and signal processing modules to RIS to receive control instructions, but the corresponding cost and system power consumption increase. The cost and power supply requirements of large-scale outdoor deployment limit the application of this solution.

[0086] In view of the above problems, the present disclosure provides a base station system including a communication auxiliary component and a base station, wherein the communication auxiliary component can be the above-mentioned smart antenna.

[0095] Figure 8 A schematic diagram of a communication auxiliary component according to an embodiment of the present disclosure is shown. Figure 8, the antenna panel 4021 may be composed of an antenna structure and an adjustable structure, wherein the antenna structure may include an array-arranged antenna unit, and the adjustable structure may include a periodically arranged adjustable structure unit. The antenna panel 4021 may include a plurality of periodically arranged array units, wherein each array unit is composed of one or more antenna units and one or more adjustable structure units. The antenna panel 4021 may also include a control signal input line for the adjustable structure, and control information for the adjustable structure may be transmitted to a specified adjustable structure unit through the signal input line. The array antenna unit receives the beam output by the base station, and adjusts the beam according to the configuration signaling sent by the base station to output an adjusted beam, thereby assisting the communication process between the base station and the terminal. The adjustment of the electromagnetic parameters of the output beam may be achieved by controlling the adjustable structure, and the adjustment control information (e.g., the first control information) is generated by the driving control structure 4022 based on the configuration instruction of the base station. Among them, the adjustable structure can be realized by a variety of materials or devices, such as PIN diodes, switches, varactors, liquid crystals, ferrite materials, MEMS, graphene, and its periodic arrangement can be rectangular arrangement, triangular arrangement, periodic arrangement based on specific functions, etc. The corresponding relationship between the number of adjustable structural units and array antenna units can be one-to-many, many-to-one, and many-to-many. According to this embodiment, the antenna panel only retains the beam receiving, adjusting and transmitting structures, which can effectively reduce hardware costs and system power consumption, cater to the development trend of low-cost and low-power communication systems, and is conducive to large-scale deployment and application.

[0096] The communication auxiliary component may also include one or more of a signal receiving structure, a data processing structure, an energy conversion structure, and a drive power supply structure, wherein the signal receiving structure is configured to receive data signals and / or energy signals; the data processing structure is configured to receive data and forward and / or adjust the received data; the energy conversion structure is configured to receive energy signals and convert the energy signals into electrical energy; and the drive power supply structure is connected to the drive control structure and configured to supply power to the drive control structure. Figures 9 to 11 Detailed description.

[0097] Fig. 9 A schematic diagram of a communication auxiliary component according to an embodiment of the present disclosure is shown. Fig. 9 The antenna panel 4021 may also include a signal receiving structure 4024, a radio frequency device (eg Fig. 9The signal receiving structure 4024 includes a low noise amplifier, a filter, a mixer, a digital-to-analog converter), and a data processing structure 4025. The data received by the signal receiving structure 4024 can be used to assist the base station codebook optimization, perception, positioning, wireless charging and other functions. The communication auxiliary component can receive the beam sent by the terminal or the base station, part of which is received by the signal receiving structure 4024 and processed and analyzed, and part is adjusted by the antenna panel and sent in a specified direction (such as to the base station or the terminal). For example, the signal receiving structure 4023 can receive the first beam transmitted by the base station or the first part of the beam transmitted by the terminal, and the antenna panel can receive the first beam transmitted by the base station or the second part of the beam transmitted by the terminal, and adjust the second part and / or change the output direction of the second part. The signal receiving structure 4023 can forward the first part of the beam transmitted by the terminal to the base station (for example, the antenna structure of the base station). The received power is related to the number of units of the signal receiving structure 4024 and the design of the signal receiving structure. If the ratio of the number of antenna units of the antenna panel to the number of units of the information receiving structure is N:1, 1 / (N+1)^2 of the terminal input beam power is received, processed and analyzed, and the number ratio is related to factors such as the hardware cost of the communication auxiliary component, the system power consumption, and the power requirement for receiving data. In order to compensate for the loss of beam gain after the antenna panel is adjusted due to the signal receiving structure, the gain can be increased by increasing the number of array units of the antenna panel, or this power loss can be added to the base station calculation during the design process. Based on the communication auxiliary component with the above structure, the data processing structure 4025 of the communication auxiliary structure can receive the first data including the configuration signaling, and send the configuration signaling to the drive control structure. For example, the data processing structure 4025 receives the downlink data sent by the base station, which may include the configuration signaling for the communication auxiliary component calculated by the base station, and sends the configuration signaling to the drive control structure 4022 to perform the adjustment of the output beam of the communication auxiliary component. According to the communication auxiliary component of this embodiment, there is no need for the information transmission structure 403 to transmit the configuration signaling, which can reduce the hardware cost of the information transmission structure.

[0098] Optionally, the data processing structure 4025 of the communication auxiliary component can receive the second data, send the second data to the outside, or adjust the configuration signaling based on the second data and send the adjusted configuration signaling to the drive control structure or the outside. For example, the data processing structure 4025 can receive uplink data sent by the terminal, and the information in the uplink data may include at least one of the following: transmission beam information (e.g., beam ID or beam ID indication information), transmission signal quality related information (e.g., RSRP). Based on the analysis of the information, the optimized configuration signaling for the output beam of the communication auxiliary component can be obtained, and the optimized configuration signaling can be sent to the drive control structure 4022. According to this embodiment, the transmission signaling transmission overhead between the base station and the communication auxiliary component can be reduced, the response speed can be improved, the problem of offset between the transmission path and the calculation result of the base station caused by environmental changes such as wind blowing can be solved, and the utilization efficiency of the output beam power of the base station can be improved. The updated configuration signaling can be sent to the base station through the information transmission structure 403, which is used for the output beam of the base station and the subsequent configuration signaling adjustment.

[0099] Fig.10 FIG. 1 is a schematic diagram showing a communication auxiliary component according to another embodiment of the present disclosure. Fig.10 , the data received by the data receiving structure 4024 can be sent to the base station for processing and analysis through the information transmission structure 403. According to this embodiment, the hardware cost and power consumption required by the RF device and the data processing structure 4025 can be reduced without increasing the power supply requirements for the communication auxiliary components. If the data information received by the communication auxiliary component is an uplink perception and / or positioning signal, for the same measurement object, the communication auxiliary component can receive uplink data that exceeds the base station beam scanning angle and send the data to the base station to assist in the calculation of relevant parameters of the measurement object, improve the accuracy of perception or positioning, or expand the service range of the base station.

[0100] Fig.11 FIG. 1 is a schematic diagram showing a communication auxiliary component according to another embodiment of the present disclosure. Fig.11 , the communication auxiliary component may also include an energy conversion structure. If the signal receiving structure of the communication auxiliary component receives a wireless charging signal, the wireless charging signal can be converted into energy, such as electrical energy, by the energy conversion structure. The communication auxiliary component can send or store the energy converted by the energy conversion structure to the drive power supply structure 4023 to provide energy for the operation of the communication auxiliary component. According to this embodiment, the volume of the drive power supply structure can be reduced, or energy can be directly provided to the drive control structure without the drive power supply structure, thereby improving the flexibility of the deployment of the communication auxiliary component and reducing the hardware cost.

[0101] The driving power supply structure 4023 provides the driving control module 4022 with the energy required for operation, which can be in at least one of the following forms: an independent driving power supply module integrated on the communication auxiliary component side, reducing the signal transmission between the communication auxiliary component and the outside, and improving the system integration and design freedom of the communication auxiliary component; obtaining the driving power supply from the base station through an external connecting line can reduce the cost, weight, wind resistance and other problems of the power supply component, and is suitable for scenarios where the driving power is large and the power supply size required is large; obtaining external energy input wirelessly through solar panels, wireless charging receiving devices, etc., to provide energy for the driving control structure, which is suitable for the design of communication auxiliary components with small power supply requirements; the driving control component and the driving power supply component are combined with the base station, and the driving control component and the driving power supply component in the base station can provide the antenna panel of the communication auxiliary component with adjustment driving control information and energy through connecting lines or wirelessly, which is suitable for innovative application scenarios such as transparency and commonality of communication auxiliary components.

[0102] The following will refer to Figures 12 to 17 The method performed by the base station and the communication auxiliary component in the wireless communication system according to the embodiment of the present disclosure is described.

[0103] Fig.12 A flowchart of a method performed by a base station according to an embodiment of the present disclosure is shown, and Fig.13 A flow chart of a method performed by a communication assistance component according to an embodiment of the present disclosure is shown.

[0104] Reference Fig.12 In step S1201, the base station may first determine first control information for adjusting electromagnetic parameters of multiple array units of the antenna panel of the communication auxiliary component, and the first control information may be determined based on the position of the antenna panel of the base station and the position of the antenna panel of the communication auxiliary component. The position of the antenna panel of the base station and the position of the antenna panel of the communication auxiliary component include: physical position, height and / or tilt angle, but the present disclosure is not limited thereto. For example, the relative position between the antenna panel of the base station and the antenna panel of the communication auxiliary component may be determined based on the physical position, height, tilt angle, etc. of the antenna panel of the base station and the antenna panel of the communication auxiliary component, and the first control information of the electromagnetic parameters of multiple array units of the antenna panel of the communication auxiliary component may be adjusted based on the determination of the relative position.

[0105] After determining the first control information, in step S1202, the base station may include the first control information in a configuration signaling and send the configuration signaling to the communication auxiliary component. For example, the configuration signaling may be referred to Figures 4 to 5 The described information transmission structure is sent to the communication auxiliary component.

[0106] Reference Fig.13In step S1301, the communication auxiliary component may receive a configuration signaling, the configuration signaling including first control information for adjusting electromagnetic parameters of a plurality of array units of an antenna panel of the communication auxiliary component. For example, the communication auxiliary component may receive a configuration signaling sent by the base station in step S1202 from the base station, the configuration signaling including first control information determined by the base station in step S1202. The first control information may be sent to the antenna panel of the communication auxiliary component to adjust the electromagnetic parameters of a plurality of array units therein. For example, referring to Figure 6 or Figure 7 The described driving control structure 4022 can receive the configuration signaling 4032 of the base station to the antenna panel 4021 of the communication auxiliary component through the signal transmission structure 403, and output the first control information of the array unit to the antenna panel 4021.

[0107] In step S1302, the communication auxiliary component may adjust electromagnetic parameters of a plurality of array units of the antenna panel of the communication auxiliary component based on the first control information.

[0108] The configuration signaling received by the communication auxiliary component may include information related to the physical position adjustment of the physical connection structure of the communication auxiliary component and / or information related to the codebook adjustment of the antenna panel, which is used to change the output direction of the beam input by the base station after the beam is adjusted by the auxiliary node; the data information received by the data receiving structure can be used to assist the communication, perception, positioning and other functions between the base station and the terminal, and the transmitted data may be in the form of data information received by the antenna panel or data information processed by the communication auxiliary component.

[0109] According to an embodiment of the present disclosure, the method executed by the base station may also include generating control information for adjusting electromagnetic parameters of multiple array units according to a first beam and a second beam based on the position of the antenna panel of the base station and the position of the antenna panel of the communication auxiliary component, wherein the first beam is a beam transmitted by the base station and the second beam is a beam output by the communication auxiliary component.

[0110] The base station can generate first control information for adjusting the electromagnetic parameters of multiple array units based on the position of the antenna panel of the base station and the position of the antenna panel of the communication auxiliary component (for example, physical position, height and / or tilt angle), according to, for example, the input and output angles of the first beam and the second beam, for example, so that the second beam emitted by the antenna panel of the communication auxiliary component is more accurately and efficiently transmitted to the user terminal, or the first beam emitted by the base station is not transmitted to the node that does not expect to receive it, but the present disclosure is not limited to this. For example, the phase compensation information of the first beam and / or the phase compensation information of the second beam can be determined according to the direction of the first beam and the direction in which the second beam is expected to be transmitted, as well as the position of the antenna panel of the base station and the position of the antenna panel of the communication auxiliary component, and the first control information for adjusting the electromagnetic parameters of the antenna panel array unit of the communication auxiliary component can be generated in combination with this information.

[0111] An implementation of determining the first control information will be described below, but it should be noted that the present disclosure is not limited thereto.

[0112] The configuration signaling sent by the base station to the communication auxiliary component (for example, the first control information in the configuration signaling) is related to the output beam direction (the direction of the second beam) forwarded by the communication auxiliary component, the output beam angle of the base station (the angle of the first beam, i.e., the input beam of the communication auxiliary component), and the physical position information of the antenna panel, wherein the relative position, relative height, and relative angle of the antenna panel of the base station and the communication auxiliary component will affect the angle of the base station's transmit beam. The correspondence between the output beam direction of the communication auxiliary component and related factors (for example, parameters for adjusting the adjustable structure) can be calculated by the base station (for example, the controller of the base station) based on the information, or obtained by a table lookup method. Among them, according to the relative physical position information of the base station, the communication auxiliary component and the terminal, the horizontal and vertical angle information (A, B) of the direction of the beam reaching the communication auxiliary component from the base station (that is, the input beam direction of the communication auxiliary component), and the horizontal and vertical angle information (C, D) of the output beam direction of the communication auxiliary component, combined with the design-related information of the communication auxiliary component, the base station (for example, the controller of the base station) can calculate the first control information (for example, the codebook indication information index or codebook information) used by the antenna panel of the communication auxiliary component to adjust the beam direction or the electromagnetic parameters of the array unit, as shown in Table 1 below. Table 1 shows the correspondence between the direction of the input beam and the output beam of the communication auxiliary component and the codebook. Through Table 1, the configuration codebook information (codebook indication information index or codebook information) for adjusting the beam direction of the output beam of the communication auxiliary component can be determined (for example, by the controller of the base station) based on the direction of the input beam and the output beam of the communication auxiliary component, and included in the configuration signaling. The output beam direction (A, B) of the base station may be the direction of the output main lobe or side lobe of the base station, and the output side lobe information of the base station may be related to the main lobe output information of the base station and known by the base station or may be obtained by the calculation base station. The base station may query the following table, according to the obtained physical location information, the input beam direction information of the communication auxiliary component and the expected output beam direction information of the communication auxiliary component, to obtain the required configuration codebook index information for the communication auxiliary component, and send the corresponding configuration signaling to the communication auxiliary component.

[0113] Table 1

[0114]

[0115] Among them, the direction (A, B) of the beam from the base station to the communication auxiliary component is related to the position of the base station and the communication auxiliary component, and the output beam direction X of the base station; the output beam angle (C, D) of the communication auxiliary component is related to the position of the base station and the communication auxiliary component, and the distance Y between the base station and the terminal (which can be calculated by TA). The physical location information of the base station and the communication auxiliary component and the design-related information of the communication auxiliary component can be sent to the base station in advance or stored at the base station. Therefore, the configuration codebook information (codebook indication information index or codebook information) required by the communication auxiliary component can be queried through the angle information X and the distance information Y, as shown in the following Table 2. The controller of the base station can determine the configuration codebook information based on the angle information X and the distance information Y, and include the configuration codebook information in the configuration signaling.

[0118] Alternatively, the configuration signaling can be obtained by calculation of the base station (for example, the controller of the base station), and the output beam correspondence table of the communication auxiliary component can also be calculated and obtained in the manner described above, and will be stored in the base station and / or the communication auxiliary component. The adjustment of the output beam direction is achieved by adjusting the adjustable structural unit of the antenna panel of the communication auxiliary component (for example, adjusting the electromagnetic parameters of the array unit), and by adjusting the output beam phase corresponding to the antenna unit in the antenna panel corresponding to each adjustable structural unit, the phase of the beam output in the specified direction (i.e., the expected output beam direction) is consistent to form a superimposed beam enhancement effect, and the output beam phases in other directions are inconsistent to offset each other, thereby reducing the energy output in other directions. The adjustment of the adjustable structural unit of the antenna panel of the communication auxiliary component includes two parts: phase compensation of the input beam and phase compensation of the output beam in the specified direction. Combined with the control information and phase correspondence of the adjustable structural unit of the antenna panel of the communication auxiliary component, the control information of each adjustable structural unit can be obtained to form the driving control information of the antenna panel and its corresponding configuration signaling. The following uses an example of two-dimensional coordinates to illustrate the calculation method of input phase compensation and output phase compensation. The calculation in three-dimensional space can be performed with reference to this method. The angles are all absolute values.

[0119] The calculation method of the phase compensation information of the first beam can be, for example, as follows: Fig.14A As shown, according to the physical location information of the base station and the communication auxiliary component, the height difference between the base station antenna panel and the communication auxiliary component antenna panel can be obtained as h, the horizontal distance is L, and the inclination angle of the vertical plane is θ B and θ R The design parameters of the antenna panel of the communication auxiliary component are known, and the antenna unit spacing is d. Based on the above information, it can be calculated that Fig. 14B Information about the angles shown in:

[0120] θ 1 =arctan(h / L)

[0121]

[0122] θ 3 =90-θ B +θ 1

[0123] The transmission distance differences between two adjacent antenna units of the communication auxiliary component are L = L 1 +L 2 ,in

[0124] L 1 =d*sinθ 2

[0125] L 2 =d*cosθ 2 / tanθ 3

[0126] According to the distance difference and the working frequency of the input beam, the phase difference of the input beam of the communication auxiliary component reaching the adjacent antenna unit can be calculated, where c 0 is the speed of light in a vacuum.

[0127]

[0128] When there is a horizontal tilt angle between the base station and the array of the communication auxiliary component, it is necessary to consider the influence of the horizontal incident angle on the basis of the above calculation method, perform a three-dimensional phase difference calculation, and obtain the phase compensation information of the input beam.

[0129] The schematic diagram of the phase compensation calculation method of the second beam outputted by the communication auxiliary component in a specified direction can be, for example, as shown in Fig.15 The equivalent input curve of the front face after the phase difference compensation calculated above (equivalent input direction of the input beam) is shown as Fig.16 The dashed line r 0 As shown, the communication auxiliary components are 0 The second beam is sent in the target direction with a vertical angle of θ, where θ is related to the relative position of the communication auxiliary component and the terminal. The distance between the communication auxiliary component and the terminal is L3, and the height difference is h3. When the terminal is far away, L3 can be approximated as L3=L, and the angle θ is calculated to be θ=arctan(h3 / L3).

[0130] The transmission distance difference between adjacent antenna units of the antenna panel of the communication auxiliary component is dsinθ, and the phase difference value that needs to be compensated for the corresponding adjacent antenna units is

[0131]

[0132] The above method can be used to calculate the compensation phase information of the adjustable structure required for each antenna unit of the antenna panel. and Combined with Fig.17 The characteristic curve of the adjustable structure shown (such as the relationship curve between the driving voltage and the output phase) obtains the driving control information required for each adjustable structural unit of the antenna panel (such as the amplitude information of the adjustment voltage), that is, the first control information for the array unit of the antenna panel.

[0133] Based on the calculated first control information, an adjustment configuration signaling for the adjustable structure of the antenna panel is generated. The calculation of the configuration signaling can be completed by a base station (for example, a controller of a base station) and / or by a drive control module of the antenna panel.

[0134] The configuration signaling includes at least one of the following: control information on the relative position or angle between the base station and the communication auxiliary component, and control information on the array unit of the communication auxiliary component (such as configuration codebook information).

[0135] The first control information in the configuration signaling for adjusting the array unit of the communication auxiliary component has been described above. The second control information in the configuration signaling for adjusting the relative position or angle between the base station and the communication auxiliary component will be described below.

[0136] The relative position or angle between the base station and the communication auxiliary component can be adjusted by adjusting the posture of the communication auxiliary component. The adjustment can be achieved by adjusting the relative position or angle between the base station and the communication auxiliary component. Figure 4 and Figure 5 The physical connection structure described sends the second control information so that it can adjust the height, horizontal position, tilt angle, etc. of the communication auxiliary component based on the second control information. The second control information used for the adjustment can be determined according to the direction of the first beam, the position of the base station and the position of the communication auxiliary component. By adjusting the posture of the communication auxiliary component, the receiving area of ​​the communication auxiliary component for the output beam of the base station can be increased, and the signal reception conversion efficiency can be improved, or the interference of obstacles (such as the transmitting antenna of the base station) on the outgoing beam can be reduced, or the direction of the antenna panel can be adjusted to increase the coverage of the beam.

[0137] The following will refer to Fig.18 A method involving attitude adjustment of a communication auxiliary component performed by a base station is described.

[0138] In step S1801, the base station may determine an adjustment method for the antenna panel of the communication auxiliary component, where the adjustment method includes: adjusting electromagnetic parameters and adjusting electromagnetic parameters and posture.

[0139] If the determined adjustment method is to adjust the electromagnetic parameters of the antenna panel array unit of the communication auxiliary component, the base station may perform steps S1802 and S1803, which are the same as those described above with reference to Fig.12 The described steps S1201 and S1202 are the same.

[0140] If the determined adjustment method is to adjust the electromagnetic parameters of the antenna panel array unit of the communication auxiliary component and the antenna panel posture of the communication auxiliary component, then in step S1804, the base station may generate first control information for adjusting the electromagnetic parameters of the antenna panel array unit of the communication auxiliary component and second control information for adjusting the posture of the communication auxiliary component. For example, the second control information may be determined based on the direction of the first beam, the location of the base station, and the location of the communication auxiliary component. In step S1805, the base station may include the first control information and the second control information in the configuration signaling and send the configuration signaling to the communication auxiliary component.

[0141] According to the base station system disclosed in the present invention, by introducing an adjustable communication auxiliary component and sending corresponding configuration signaling according to the communication requirements of the base station, the electromagnetic parameters of the output beam of the base station (such as the transmission direction) are adjusted to assist the communication between the base station and the terminal.

[0142] According to the base station system that introduces the communication auxiliary component disclosed in the present invention, the sidelobe signal can be used to serve the user's communication to improve the utilization efficiency of the output energy; or, the sidelobe signal can be adjusted to deviate from the original direction to reduce interference with the communication of other nodes; or, the output beam of the base station can be focused to increase the gain to serve the users at the edge of the cell and improve the efficiency of information transmission; or, through inter-cell collaboration, the communication of other cell terminals outside the coverage of the base station can be assisted; or, information from other nodes (such as terminals) is received for analysis and / or processing to optimize the configuration signaling of the communication auxiliary component, reduce the impact of environmental changes on transmission efficiency, and reduce the signaling transmission between the base station and the communication auxiliary component; or, wireless charging energy can be received to reduce the cost and weight of the communication auxiliary component, which is conducive to the large-scale deployment and application of the communication auxiliary component; or, perception and / or positioning signals can be received to improve the accuracy of base station perception and / or positioning.

[0143] As the communication frequency increases, the signal transmission attenuation becomes greater. The service coverage of the base station can be guaranteed by using array antennas or increasing the base station output power. Large array antennas and high-power devices will lead to a significant increase in hardware and power supply costs, and will also cause electromagnetic interference problems.

[0144] In the design process of array antennas, a large number of PIN tubes with mature production processes are used as phase adjustment structures to achieve fast beam switching and adjustment. The wavelength of the millimeter wave band becomes shorter, and the physical spacing between array antenna units becomes smaller, resulting in limited design space. The solution of placing multiple PIN tubes in a unit period with high adjustment accuracy is difficult to implement and the cost will also increase. Therefore, common array antennas can only achieve 1-bit or 2-bit antenna scanning accuracy (the unit phase can be adjusted in steps of 180° or 90°), and the low output energy utilization and signal interference caused by the antenna sidelobes are difficult to solve.

[0145] Fig.19 A schematic diagram showing the operation of a base station system according to an embodiment of the present disclosure is shown.

[0146] like Fig.19 As shown, in the process of communication between the base station and the terminal, in order to maximize the utilization rate of the base station output energy, the main lobe beam of the base station output beam is used for communication, hereinafter referred to as the "first signal", and the side lobe beam of the base station antenna radiates energy in other directions, hereinafter referred to as the "second signal", and the number of second signals can be multiple. The existence of the side lobe beam may interfere with the communication of other users. Therefore, in the antenna design process of the base station, the attenuation level of the side lobe beam relative to the main lobe beam will be limited. This requirement can be achieved by reducing the unit spacing, increasing the window function, etc., and the corresponding hardware cost and design difficulty will increase accordingly. In this embodiment, an adjustable communication auxiliary component is introduced, which is configured to receive the side lobe beam and adjust the side lobe beam based on the configuration signaling to form an output beam pointing to a predetermined direction. For example, the antenna panel of the communication auxiliary component can receive the second signal energy output by the base station and adjust and forward it to form a "third signal" transmitted in a specified direction. For different application scenarios, the third signal can be configured to assist the communication of the first signal, or to reduce interference with the communication of other terminals.

[0147] When the base station and the terminal can communicate through the first signal, the base station can configure a third signal, for example, to point the third signal to the terminal, and serve the same terminal communication together with the first signal to improve the utilization efficiency of the base station output energy. The base station can determine the first control information based on the location of the base station and the location of the terminal, and the first control information is used to enable the communication auxiliary component to transmit the third signal to the terminal. For example, in the process of communicating with the terminal, the base station (for example, the controller of the base station) can obtain the beam information used for communication with the terminal, and calculate the physical location information of the terminal in combination with the physical location information stored in the base station, and the beam information includes: the beam information selected by the terminal (or beam indication information, such as beam ID), the distance-related information between the base station and the terminal (such as TA), and the beam frequency information. The output beam main lobe and side lobe information of the base station, the direction of the beam output by the communication auxiliary component, and the configuration signaling correspondence relationship information can be obtained by one or more of the following ways: stored in the base station in advance, obtained based on the test and feedback of other nodes, informed by other nodes, and calculated based on the beam information of the base station. The base station can determine the corresponding sidelobe output beam direction based on the beam information selected by the terminal, and combine the physical location related information of the base station and the communication auxiliary component to calculate the output beam direction of the communication auxiliary component required to adjust the third signal for serving the terminal, and the configuration signaling corresponding to the output beam direction, and send the configuration signaling to the communication auxiliary component through the information transmission structure.

[0148] The antenna panel of the communication auxiliary component has a large number of antenna units, and the beam width of the third signal is narrow. In order to improve the accuracy of the third signal serving the terminal, or to consider the impact of environmental disturbances and other factors on the communication quality, the base station can configure the communication auxiliary component and the terminal to fine-tune the direction of the third signal and feedback to select the optimal beam while keeping the output beam unchanged. Specifically, the base station (for example, the communication structure of the base station) can send multiple configuration signaling to the communication auxiliary component, and the communication auxiliary component sends multiple beams in different directions (such as SSB, CSI-RS) according to the multiple configuration signaling of the base station. The terminal performs signal quality measurement (such as RSRP) on the received multiple beams, and feedbacks the optimal beam-related information (such as beam ID), and the base station receives the beam measurement result-related information fed back by the terminal (the selected optimal beam ID). Among them, the spatial interval and angle range of the third signal scan are determined by the base station, and this parameter is related to factors such as the beam width of the communication auxiliary component, the scanning accuracy of the communication auxiliary component, and the receiving beam width of the terminal. The measurement information fed back by the terminal may include at least one of the following: beam indication information (beam ID or beam ID indication information), beam strength information (RSRP), the correspondence between beam strength and beam indication information, and one or more beam indication information selected by the terminal. The third signal beam scanning and beam selection process of the communication auxiliary component can be completed by the base station configuration terminal and the selection result can be fed back to the base station, or the base station configures the terminal to feed back the measurement result and the beam correspondence, and the base station makes a judgment and selection. The base station (for example, the controller of the base station) obtains the optimized configuration signaling based on this information, and sends the updated configuration signaling to the communication auxiliary component (for example, the drive control structure of the communication auxiliary component). The antenna panel of the communication auxiliary component can adjust and transmit one or more beams selected by the terminal based on the optimized configuration signaling.

[0149] Fig. 20 A schematic diagram showing the operation of a base station system according to another embodiment of the present disclosure is shown.

[0150] Reference Fig. 20, if there is an edge user terminal 2 of an adjacent cell in the direction of the second signal, and the second signal points to the user terminal 2, if the base station has no communication auxiliary component or the communication auxiliary component cannot change the propagation direction of the sidelobe beam of the base station, the second signal will interfere with the communication of the terminal 2. At this time, the transmission direction of the second signal can be adjusted by the communication auxiliary component to avoid or reduce the impact on the terminal 2. For example, the base station can determine the first control information according to the position of the base station and the position of the terminal 2, and the first control information enables the communication auxiliary component to adjust the direction of the second signal so that the obtained third signal does not point to the terminal 2. The third signal can be used for the communication of the communication terminal 1 of the service base station, or the transmission direction of the third signal is a direction that does not interfere with the surrounding terminals. The interference information can be measured by the terminal 2 and fed back to the service cell base station of the terminal 2. The service cell base station shares the physical location information of the terminal 2 with the base station or the node communicating with the base station through direct or indirect communication between base stations. For example, the communication structure of the base station can receive the physical location information. The base station determines whether the second signal interferes with the terminal 2 in combination with the physical location information and the sidelobe direction of the base station, and calculates the configuration signaling for improving the interference and sends it to the communication auxiliary component. It should be noted that although the present embodiment is described based on the main lobe beam and the side lobe beam, it is only exemplary and the present disclosure is not limited thereto.

[0151] Fig.21 A schematic diagram showing the operation of a base station system according to another embodiment of the present disclosure is shown.

[0152] The problem of increased attenuation of communication signal transmission in high-frequency bands can be solved by increasing the gain of the output beam. This embodiment can narrow the communication beam through the communication auxiliary component and concentrate the energy in the direction of communication with the terminal without increasing the output power of the base station, thereby improving the signal reception strength at the edge of the cell and realizing low-cost upgrade and transformation of the original base station. In the design process of the communication auxiliary component, in order to reduce its cost and power consumption, active devices are used as little as possible, and the system power consumption is low, mainly the power consumption required for driving power supply, which is suitable for making large-sized array antennas with a high number of units. When the base station communicates with the terminal at the edge of the cell, the signal attenuation of the transmission path is small, and the base station can communicate directly with the terminal. The communication auxiliary component is configured to reduce the sidelobe beam or is configured not to affect the base station communication (for example, the communication auxiliary component is configured to adjust the direction of the sidelobe beam to outside the beam coverage range of the base station). When the base station is far away from the terminal, the base station can communicate with the terminal through the beam forwarded by the communication auxiliary component with the help of the beam narrowing characteristics of the communication auxiliary component. Fig.21As shown, the terminal UE2 is far away from the base station. At this time, the base station can configure the communication auxiliary component to focus and narrow the beam of the first signal to form a high-gain third signal, and transmit the third signal to the terminal UE2 to communicate with the terminal UE2 through the third signal. For example, the base station can determine the first control information based on the position of the base station and the position of the terminal 2, and the first control information is used to make the communication auxiliary component focus on the received first signal and adjust its direction to point to the terminal 2 to form the third signal.

[0153] During the communication process between the base station and the terminal, the terminal can feedback the information related to the received signal power (such as RSRP), the physical location related information, and the beam related information. When the received power does not meet a certain threshold requirement, the base station can choose to communicate with the terminal through the high-gain signal (hereinafter referred to as the "third signal") formed by forwarding the communication auxiliary component. Among them, the threshold information is related to the hardware design and transmission requirements of the terminal. This information can be calculated by the node according to the transmitted data information (such as bit error rate), or obtained by other nodes or network configuration, or stored in advance at the node. The node can be a terminal, a base station, a MAC layer, and an RRC layer. The base station (for example, the controller of the base station) can generate configuration signaling based on the signal power related indication information indicating whether the power meets the threshold, according to the location information of the base station, the communication auxiliary component and the terminal. For example, according to the physical location information of the base station and the communication auxiliary component, the direction of the first signal sent by the base station to the communication auxiliary component and the corresponding base station output beam information are calculated, and the terminal location information obtained by combining the physical location and beam information reported by the terminal is combined to obtain the configuration signaling required for the communication auxiliary component to output the direction information of the third signal. The base station sends the configuration signaling to the communication auxiliary component through the information transmission structure, and uses the high-gain third signal to serve the remote terminal.

[0154] Fig. 22 A schematic diagram showing the operation of a base station system according to another embodiment of the present disclosure is shown.

[0155] According to an embodiment of the present disclosure, a base station may send multiple beams to a terminal to be communicated, and the multiple beams may include a beam sent directly to the terminal and at least one beam sent to a communication auxiliary component, wherein the base station also sends multiple configuration signalings corresponding to the at least one beam to the communication auxiliary component. In one embodiment, the multiple configuration signalings are different from each other.

[0156] like Fig. 22As shown, during the access process between the base station and the terminal, the base station (for example, the antenna structure of the base station) sends multiple reference signals (such as SSB, CSI-RS), and also sends different multiple reference signals (such as SSB, CSI-RS) in the direction of the output beam pointing to the communication auxiliary component according to the position of the communication auxiliary component, and the base station (for example, the communication structure of the base station) sends multiple groups of configuration signaling to the communication auxiliary component, so that the communication auxiliary component forwards and enhances (for example, focuses and narrows) the multiple beams in different directions. The terminal measures the signal quality (such as RSRP) of the multiple beams sent by the base station and the multiple beams emitted by the communication auxiliary component, compares and feeds back the optimal result and beam indication information (such as beam ID) to the base station, and the base station communicates with the terminal based on the fed-back beam information. If the beam selected by the terminal is a beam directly emitted by the base station, the communication auxiliary component can be based on the reference Figure 16-18 The described implementation works to improve the energy utilization efficiency of the base station; if the beam selected by the terminal is a beam forwarded and enhanced by the communication auxiliary component, the base station (e.g., the communication structure of the base station) sends a configuration signaling corresponding to the selected beam to the communication auxiliary component to direct the outgoing beam to the communication auxiliary component. For the same base station output power, after forwarding by the communication auxiliary component, the gain of the output beam becomes larger, which can increase the coverage of the cell.

[0157] Fig.23 A schematic diagram showing the operation of a base station system according to another embodiment of the present disclosure is shown.

[0158] Usually the scanning range of the base station antenna is limited (usually the base station has a scanning range of ±60°). The existing base station design uses multiple groups of antennas to jointly serve end users in different areas, such as Fig.23 As shown, cell 3 provides services for terminals within its coverage. By introducing communication auxiliary components, base stations of adjacent cells can be coordinated to assist edge users in communicating and increase signal transmission speed. Specifically, when cell 3 communicates with terminals within its service range, information related to the physical location of the terminal can be sent to an adjacent cell (such as cell 1), and the sending method can be direct sending (such as backhaul) or sending through other nodes (such as RRU, core network). The base station of cell 1 adjusts the output of the first signal based on the terminal information and sends it to the communication auxiliary component. For example, based on the location of the base station and the location of the terminal, it calculates and generates configuration instructions and sends them to the communication auxiliary component to point the third signal direction to the terminal, which is used to assist cell 3 in communicating with the terminal. Among them, the third signal can be formed by focusing and narrowing the first signal.
