[0201] This application presents a method for determining operating modes, applied to a communication system assisted by a first device (RIS). Taking a RIS-assisted communication system as an example, the RIS can control electromagnetic signals in wireless communication in real time. By controlling adjustable elements in the RIS device units, the electromagnetic parameters of reflected or transmitted electromagnetic waves, such as amplitude, phase, polarization, and even orbital angular momentum, can be changed programmatically. For example, by controlling the phase of the reflected or transmitted electromagnetic waves of each device unit, different forwarding phase patterns are formed. The wireless response signals of each device unit are superimposed to form specific beam propagation characteristics on a macroscopic scale, thereby creating different operating modes. First, a mapping relationship is established between the location of the terminal (User Equipment, UE) and the RIS forwarding beam and forwarding phase pattern. Then, the UE's location information is used to assist in determining the RIS forwarding phase pattern, reducing the training overhead of the RIS phase pattern and improving the performance of the communication system.

[0202] The following examples illustrate the method for quickly determining the RIS forwarding phase pattern, using the existence of a communication link without RIS assistance between the network side and the terminal as examples:

[0203] 1. There is a communication link between the network side and the terminal without RIS assistance.

[0204] The base station coverage area is divided into grids. The granularity of the grid division is determined based on the coverage range of the RIS narrow forwarding beam. Factors affecting the width of the RIS forwarding beam include the number of RIS electromagnetic units and the forwarding phase pattern. Each grid represents a different signal coverage location, corresponding to a RIS narrow beam, i.e., a RIS forwarding phase pattern.

[0205] 1. There is a communication link without RIS assistance between the network-side equipment and the UE, such as... Figure 4 As shown.

[0206] 2. The network-side equipment and the UE complete the positioning process through link 1. Link 1 can be a direct / reflected / scattered / diffracted path.

[0207] 3. The network-side equipment obtains the UE's location information and positioning error information. The location information includes distance, angle, etc., and the positioning error information is at least one of the following: the current positioning technology, positioning quality information, or other information that directly or indirectly reflects the positioning accuracy.

[0208] 4. Location information is obtained through one or more of GNSS, RFID, UWB, Bluetooth, Wi-Fi, mobile network-based positioning technology, or other related positioning technologies.

[0209] (a) If the positioning error is less than or equal to a preset threshold, for example, the size of a grid area, where m possible UE location information correspond to one grid, such as... Figure 5 As shown in Table 1, a mapping table between the grid and the RIS forwarding phase pattern is established. The network-side device determines the RIS forwarding phase pattern according to the UE location information and Table 1, sends control commands to the RIS, and establishes the RIS-assisted communication link 2.

[0210] Table 1. Mapping table between grid and RIS forwarding phase pattern (one of the tables)

[0211] UE position Grid RIS phase pattern 1,…,m 1 1 m+1, m+2,..., 2m 2 2 … … … (n-1)*m+1,..., n*m n n

[0212] (b) If the positioning error exceeds a preset threshold, for example, the size of a grid area, where one UE location information corresponds to m grids, meaning the UE's actual location may be within m grids, such as... Figure 6 As shown in Table 2, a mapping table is established between the grid and the RIS forwarding phase pattern.

[0213] Table 2 Mapping Table of Grid and RIS Forwarding Phase Pattern (Part Two)

[0214] UE position Grid RIS phase pattern 1 1,2,…,m 1,2,…,m 2 m+1, m+2,..., 2m m+1, m+2,..., 2m … … … n (n-1)*m+1,..., n*m (n-1)*m+1,..., n*m

[0215] Based on the UE location information, the network-side equipment determines m RIS forwarding phase patterns according to Table 2:

[0216] Method 1: Send control commands corresponding to m forwarding phase patterns to the RIS and notify the UE to perform beam measurement. The UE measures the beams corresponding to different patterns, selects the pattern corresponding to the optimal beam, and establishes the RIS-assisted communication link 2.

[0217] Method 2: Select one from the m RIS forwarding phase patterns and send the corresponding control command to the RIS. The selection method can be:

[0218] (a) Select one randomly.

[0219] (b) Select the RIS forwarding phase pattern corresponding to the center grid of multiple grids corresponding to m RIS forwarding phase patterns and send the corresponding control command to the RIS.

[0220] This solution is applicable to single base station, single RIS, or multiple base stations and multiple RIS scenarios.

[0221] Furthermore, the above grid division can be based on a three-dimensional plane.

[0222] Second, there is no communication link between the network side and the terminal without RIS assistance.

[0223] Network-side equipment can scan the required angle range and scan angle step size, or it can be different base station coverage sub-regions. Each angle / sub-region corresponds to a RIS wide forwarding beam, such as... Figure 7 and Figure 8 n RIS wide forwarding beams are determined, and each wide beam corresponds to a RIS forwarding phase pattern for wide beam scanning.

[0224] The base station coverage area is divided into grids. The granularity of the grid division is determined based on the coverage range of the RIS narrow forwarding beam. Factors affecting the width of the RIS forwarding beam include the number of RIS electromagnetic units and the forwarding phase pattern. Each grid represents a different signal coverage location, corresponding to one RIS narrow beam, i.e., one RIS forwarding phase pattern. The specific division method is the same as in the example above, and will not be repeated here.

[0225] 1. There is no communication link between the network-side equipment and the UE without RIS assistance, such as... Figure 9 As shown.

[0226] 2. The network-side equipment, based on the determined n RIS wide forwarding beams and the corresponding RIS forwarding phase patterns, sends control commands corresponding to the n forwarding phase patterns and corresponding beam information, such as SSB, to the RIS. The UE measures the beams corresponding to different patterns. For example, it selects the pattern corresponding to the optimal beam based on RSRP, completes the wide beam search, and establishes the RIS-assisted communication link 1.

[0227] 3. The network-side equipment and the UE complete the positioning process through link 1.

[0228] 4. The network-side equipment obtains the UE's location information and positioning error information. The location information includes distance, angle, etc., and the positioning error information is at least one of the following: the current positioning technology, positioning quality information, or other information that directly or indirectly reflects the positioning accuracy.

[0229] 5. Location information is obtained through one or more of GNSS, RFID, UWB, Bluetooth, Wi-Fi, mobile network-based positioning technology, or other related positioning technologies;

[0230] (a) If the positioning error is less than or equal to a preset threshold, for example, the size of a grid area, where m possible UE location information correspond to one grid, such as... Figure 5 As shown in Table 1, a mapping table between the grid and the RIS forwarding phase pattern is established. The network-side device determines the RIS forwarding phase pattern according to the UE location information and Table 1, and sends control commands to the RIS to obtain a more directional RIS narrow forwarding beam, thereby improving the gain of link 1.

[0231] (b) If the positioning error is greater than a preset threshold, for example, the size of a grid area, where one UE location information corresponds to m grids, such as Figure 5 As shown in Table 2, a mapping table between grids and RIS forwarding phase patterns is established. The network-side device determines m RIS forwarding phase patterns based on the UE location information and Table 2.

[0232] Method 1: Send control commands corresponding to m forwarding phase patterns to the RIS and notify the UE to perform beam measurement. The UE measures the beams corresponding to different patterns, selects the pattern corresponding to the optimal beam, obtains a more directional RIS narrow forwarding beam, and improves the gain of link 1.

[0233] Method 2: Select one from the m RIS forwarding phase patterns and send the corresponding control command to the RIS. The selection method can be:

[0234] (a) Select one randomly.

[0235] (b) Select the RIS forwarding phase pattern corresponding to the center grid of multiple grids corresponding to m RIS forwarding phase patterns and send the corresponding control command to the RIS.

[0236] It is applicable to single base station, single RIS, or multiple base station and multiple RIS scenarios.

[0237] For future integrated sensing scenarios, such as the integrated design of base stations and radar, the positioning information can be obtained by the network-side equipment transmitting radar detection signals and then measuring the echo signals of the UE. That is, the UE position is determined by radar detection to assist the RIS in quickly determining the phase pattern.

[0238] The embodiments of this application can quickly determine the optimal phase pattern for RIS-assisted communication, reduce the training overhead of RIS phase pattern, and improve the performance of the communication system.
