[0035] The terminal access method provided in the present application will be described in detail below with reference to the accompanying drawings.

[0036] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0037] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0038] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0039] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0040] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical items or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

[0041] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0042] In order to clearly describe the technical solutions of the embodiments of the present application, the technical terms involved in the present application are briefly introduced below.

[0043] Network-controlled repeater (NCR) technology is based on RF repeater technology. Compared with RF repeaters, NCR has the ability to receive and process control information from the network side.

[0044] Metasurface is a two-dimensional realization of electromagnetic superconducting materials. Metasurface is composed of a series of periodically arranged electromagnetic unit structures, which can be used as a carrier for implementing electromagnetic control. Among them, the unit structures are assembled into some adjustable elements to obtain the reconfigurability of electromagnetic wave control. The adjustable elements can be components such as semiconductor diodes, varactor diodes, liquid crystals and micro-electro-mechanical systems (MEMS) switches.

[0045] Reconfigurable intelligent surface (RIS) is an extension of metasurface technology. RIS not only has the electromagnetic control capability of traditional metasurfaces, but also adds intelligent control functions. RIS can actively and intelligently control electromagnetic waves in space in a programmable way to form an electromagnetic field with controllable amplitude, phase, polarization and frequency.

[0046] The above is an introduction to the technical terms involved in this application, which will not be repeated below.

[0047] In order to improve network coverage performance, different types of network nodes such as macro base stations, micro base stations, and repeaters will be used in mobile communication network deployment to achieve wide and deep coverage of wireless networks. As mobile communication networks evolve to the fifth generation mobile communication technology advanced (5G-A) and the sixth generation mobile communication technology (6G), various new relay communication technologies will be introduced into mobile communication network deployment, providing more diverse technical solutions for network deployment.

[0048] For example, NCR can optimize and control its amplification and forwarding strategy and adjust the forwarding beam based on the control information sent from the network side, which can effectively improve the efficiency of signal amplification and forwarding.

[0049] The introduction of RIS has changed the wireless propagation environment from passive adaptation to active control, and built an intelligent wireless environment. RIS can significantly improve the transmission performance between communication devices and enhance the coverage performance of wireless communication systems by dynamically adjusting the wireless channel environment. In the relay communication system, using RIS as a forwarding device can assist the base station in enhancing coverage, especially when covering the cell edge and blind spot areas. The signals sent by the base station are mainly forwarded (reflected / transmitted) to the terminal through RIS, and the signals sent by the terminal can also be forwarded to the base station through RIS. RIS can point the beam to a specific terminal through beamforming, expand the coverage range and suppress interference.

[0050] In a relay communication system, the forwarding device controls the forwarding beam based on technologies such as beamforming, so that the forwarding beam points to the terminal in the coverage area to assist the communication between the terminal and the base station. If there are multiple forwarding devices in the relay communication system, the terminal will obtain different communication performance when it accesses different forwarding devices. The existing technology statically configures the forwarding device accessed by the terminal, and cannot determine the optimal forwarding device for the terminal to access before the forwarding device controls the beam for beam forwarding, nor can it dynamically adjust the forwarding device accessed by the terminal during the signal forwarding process, which will lead to a decrease in terminal communication performance.

[0051] In response to the above technical problems, the present application provides a terminal access method, the idea of ​​which is: to be able to determine the first forwarding device corresponding to the first terminal based on the location information of the first terminal and the location information of the forwarding device controlled by the base station, so that the first terminal can access the first forwarding device that is closer, reduce the forwarding signal propagation path loss, and improve the signal strength received by the first terminal, and then instruct at least one first forwarding device to complete the signal forwarding work from the terminal to the base station by sending a first indication message, thereby improving the relay communication quality and enhancing the terminal communication performance.

[0073] It should be noted that the system architecture described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided in the embodiments of the present application.

[0074] See also Figure 3 , is a flow chart of a terminal access method provided in an embodiment of the present application. Figure 3 As shown, the terminal access method provided in the present application can be implemented by the above-mentioned base station, and specifically includes the following steps S201 to S203.

[0075] S201. Obtain location information of a first terminal.

[0076] In some embodiments, the location information of the first terminal is acquired based on base station positioning technology.

[0077] Exemplarily, the position of the terminal can be estimated through positioning technology based on the characteristics of the wireless signal between the base station and the first terminal. For example, the base station can determine the terminal location information based on at least one of the following methods: received signal strength indication (RSSI), time of arrival (TOA), time difference of arrival (TDOA), and angle of arrival (AOA).

[0078] In some embodiments, the first terminal obtains the location information of the first terminal based on the terminal positioning technology, and sends the location information to the base station.

[0079] Exemplarily, the first terminal obtains the location information through a satellite positioning system, or obtains the location information based on the location information of a wireless fidelity (WI-FI) access point (AP), and sends the location information to the base station. The satellite positioning system may be a global positioning system (GPS), a global navigation satellite system (GNSS), etc.

[0080] S202: Determine a first forwarding device corresponding to the first terminal based on the location information of the first terminal and the location information of the forwarding device controlled by the base station.

[0081] The distance between the first forwarding device and the first terminal is less than a preset distance, and the first terminal is within the coverage of the first forwarding device. A control interface exists between the forwarding device controlled by the base station and the base station, the control interface is used for signaling interaction, and the forwarding device can forward the beam transmitted by the base station.

[0082] In some embodiments, the first forwarding device corresponding to the first terminal is determined by a clustering method, wherein the clustering method includes: hierarchical clustering, K-means clustering, density-based spatial clustering of applications with noise (DBSCAN), self-organizing map (SOM), mean shift clustering, system clustering algorithm, etc.

[0083] For example, Figure 4 As shown, step S202 can be implemented as the following steps S2201-S2202.

[0084] S2201. Input the location information of the first terminal and the location information of the forwarding device controlled by the base station into a clustering algorithm model to obtain a forwarding device cluster.

[0085] The forwarding device cluster includes at least one forwarding device controlled by a base station, and the distance between any forwarding device in the forwarding device cluster and the first terminal is less than a preset distance.

[0086] In some embodiments, the clustering algorithm model may be a K-means clustering model, a system clustering algorithm model, a DBSCAN model, etc. The forwarding device cluster includes at least one forwarding device controlled by a base station.

[0087] S2202: Use a forwarding device in the forwarding device cluster that can cover the first terminal as a first forwarding device.

[0088] The above-mentioned forwarding device capable of covering the first terminal means that: the beam forwarded by the forwarding device can cover the first terminal.

[0089] In some embodiments, a base station controls multiple forwarding devices, each of which has a different coverage range. There may be some forwarding devices in the forwarding device cluster whose beams cannot cover the first terminal. Therefore, it is necessary to determine the forwarding devices in the forwarding device cluster that can cover the first terminal based on the coverage range of the forwarding devices to obtain the first forwarding device.

[0090] In some embodiments, there are multiple first terminals, and the multiple first terminals constitute a first terminal cluster, and the first terminal cluster is obtained based on a clustering algorithm model. Exemplarily, the location information of the terminal that implements wireless communication through the base station is input into the clustering algorithm model to obtain multiple clustering centers, and multiple terminal clusters are obtained based on the multiple clustering centers, each terminal cluster includes multiple terminals, and the first terminal cluster is any one of the multiple terminal clusters.

[0091] It should be understood that determining the first forwarding device corresponding to the first terminal based on the location information of the first terminal cluster composed of multiple first terminals can ensure the accuracy of the output of the clustering algorithm model. At the same time, it can also save computing resources, meet the forwarding needs of each terminal when there are multiple first terminals, and improve the overall coverage performance of multiple terminals.

[0092] In some embodiments, there are multiple first forwarding devices, and the multiple first forwarding devices constitute a first forwarding device set, and the forwarding devices in the forwarding device cluster that can cover the first terminal are used as the first forwarding device set. When there is only one first terminal, at least one first forwarding device in the first forwarding device set forwards the signal of the first terminal.

[0093] S203: Send a first indication message to the first forwarding device, where the first indication message is used to instruct the first forwarding device to forward a signal of the first terminal.

[0094] In some embodiments, the first indication message may be any one of a radio resource control (RRC) message, a medium access control control element (MAC CE) or downlink control information (DCI).

[0095] In some embodiments, the first indication message carries a beam identifier, and the beam identifier is used to instruct the first forwarding device to adjust the current beam to the beam corresponding to the beam identifier. The beam direction corresponding to the beam identifier points to the first terminal, and the beam identifier can be determined based on the location information of the target terminal.

[0096] Exemplarily, the above-mentioned determination of the beam identifier based on the location information of the target terminal can be implemented as the following steps a1-a3.

[0097] Step a1: based on the location information of the first terminal, determine the beam direction to be the direction pointing to the first terminal.

[0098] Step a2: determine a beamforming codebook corresponding to the beam direction based on the beam direction.

[0099] Step a3: determine the beam identifier based on the beamforming codebook.

[0100] Among them, the beamforming codebook corresponds to the beam identifier one by one, and the corresponding relationship between the beamforming codebook and the beam identifier is preset in the base station and the forwarding device controlled by the base station.

[0101] It needs to be understood that the correspondence between the beam forming codebook and the beam identifier is preset in the base station, so that the base station can determine the beam identifier based on the location information of the target terminal, and the correspondence between the beam forming codebook and the beam identifier is preset in the forwarding device controlled by the base station, so that the forwarding device can determine the beam forming codebook based on the beam identifier, and adjust the current beam to the beam corresponding to the beam identifier based on the beam forming codebook, and the adjusted beam points to the first terminal.

[0102] In some embodiments, after sending the first indication message, the base station may obtain the signal strength of the first terminal, update the first forwarding device based on the signal strength, and switch the forwarding device during the signal forwarding process to meet the signal strength requirement of the first terminal. Figure 5 As shown, after S203, the terminal access method provided in the embodiment of the present application may further include the following S204-S206:

[0103] S204: Acquire the signal strength of the first terminal based on a preset period.

[0104] The signal strength of the first terminal refers to the signal strength obtained when the first terminal receives a signal directly sent by the base station via a downlink, or when the first terminal receives a base station signal forwarded by a first forwarding device and measures the received signal.

[0105] In some embodiments, the first terminal sends the measured signal strength based on a preset period, so that the base station can periodically obtain the signal strength of the first terminal.

[0106] Exemplarily, the base station sends a pilot signal through a downlink based on a preset period, and accordingly, the first terminal receives the pilot signal through the downlink, measures the pilot signal to obtain a signal strength of the downlink, and sends the result to the base station.

[0107] In some embodiments, there are multiple first terminals, and the multiple first terminals constitute a first terminal cluster. The above-mentioned acquisition of the signal strength of the first terminal based on the preset period can be implemented as follows: acquiring the signal strength of the first terminal cluster based on the preset period, and using the signal strength of the first terminal cluster as the signal strength of the first terminal. The signal strength of the first terminal cluster is the average value of the signal strength of each first terminal in the first terminal cluster.

[0108] S205: Update the first forwarding device corresponding to the first terminal based on the signal strength to obtain an updated first forwarding device.

[0109] In some embodiments, when the signal strength of the first terminal is less than a signal strength threshold, the first forwarding device is updated, wherein the signal strength threshold is determined based on a signal strength requirement of the first terminal.
