[0059] Embodiments of the present application provide a network device, a first terminal device, and a communication method.

[0060] In a first aspect, an embodiment of the present application provides a communication method, which is applied to a network device, such as Figure 1 Shown, including:

[0065] S201. Send terminal device information to a network device based on the location information and service requirements of the first terminal device.

[0066] In a third aspect, an embodiment of the present application provides a communication method, which is applied to a communication system including a network device and a first terminal device, such as Figure 3 Shown, including:

[0067] S301. A first terminal device sends terminal device information to a network device according to the location information and service requirements of the first terminal device.

[0069] S303: Determine first indication information according to the terminal device information, where the first indication information is used to instruct to turn on or off the RIS device;

[0070] S304: Send the first indication information to the RIS device.

[0071] Next, Figure 1 、 Figure 2 or Figure 3 The communication method shown is described.

[0072] Here, network equipment refers to hardware devices used to build, connect, manage, and maintain networks, and implement functions such as data transmission, switching, routing, and security protection. In one example, the network equipment may be a base station.

[0073] RIS devices integrate a large number of low-cost passive reflective elements on a single plane and flexibly change the signal's reflection amplitude and / or phase through real-time parameter configuration, thereby reconfiguring the wireless transmission environment and enhancing signal coverage and transmission performance.

[0074] In the embodiment of the present application, the network device is configured with RIS devices in some areas within the coverage area, and the network device can control the RIS devices within the coverage area to be turned on or off.

[0075] In some embodiments, a RIS device may be within the coverage area of ​​multiple network devices. Depending on the specific configuration of the network devices, it can be defined that only a certain network device can control the RIS device, or it can be configured so that multiple network devices can control the RIS device. In this case, it is necessary to configure the priority of the network devices to determine which network device's instructions the RIS device will execute when there is a conflict between the control instructions of multiple network devices.

[0076] In the embodiment of the present application, the service range of the RIS device refers to the geographical area where the RIS device can effectively enhance signal strength or improve communication quality.

[0077] In a scenario where the terminal device information is detected by a network device, the network device can sense that the terminal device has entered the service range of the RIS device and can detect the corresponding terminal device information within the service range of the RIS device. The network device determines first indication information based on the detected terminal device information; the first indication information is used to instruct to turn the RIS device on or off.

[0078] In one example, the network device may sense the location information of the terminal device based on the wireless signal, and detect whether the terminal device enters the service range of the RIS device in combination with the location and service range of the RIS device.

[0079] In one example, the network device determines corresponding terminal device information within the service range of the RIS device based on the service range of the RIS device and the geographical location of the terminal device.

[0080] In the embodiment of the present application, when the terminal device information is detected by the network device, the network device controls the opening or closing of the RIS device without informing the terminal device, and the network device does not care whether the terminal device executes a high-speed service or a low-speed service.

[0081] In a scenario where terminal device information is sent to a network device by a first terminal device located within the service range, the first terminal device detects that it has entered the service range of the RIS device based on its location information and the service range of the RIS device. Based on the location information and service requirements of the first terminal device, the terminal device information is sent to the network device to request that the RIS device be turned on or off. The network device receives the terminal device information and determines first indication information based on the terminal device information. The terminal device information sent by the network device may include a request type, which may include a device turn-on request or a device turn-off request. In one example, the terminal device information is a device control request.

[0082] It can be understood that the first terminal device is any terminal device that sends terminal device information to the network device, wherein the first terminal device is located within the service range of the RIS device.

[0083] The service requirements of a first terminal device refer to the data transmission task or service quality requirements currently being performed by the first terminal device. In one example, when the first terminal device is playing a high-definition video, the first terminal device has high requirements for signal strength and latency. If the received signal is weak at this time, the first terminal device has high service requirements and needs to activate the RIS device to assist communication. On the other hand, when the first terminal device is only downloading files in the background, even if the received signal is slightly weak, it will not affect data transmission and the signal latency is low. In this case, the first terminal device does not need to activate the RIS device.

[0084] Business requirements are typically determined by factors such as application type, data rate, and delay sensitivity.

[0085] In one example, when the first terminal device is at the edge of a cell or in a blocked area, resulting in a weak received signal, and the first terminal device's task is a high-rate service, terminal device information can be sent to the network device to turn on the RIS device to enhance the strength of the received signal.

[0086] In one example, when the signal received by the first terminal device at the current location meets the current service demand, the terminal device information can be sent to the network device to shut down the RIS device to reduce unnecessary resource usage.

[0087] In the embodiment of the present application, the first terminal device may send terminal device information to the network device based on whether it can transmit data.

[0088] The first terminal device may send terminal device information to the network device to request to start the RIS device when detecting data transmission; the first terminal device may send terminal device information to the network device to request to shut down the RIS device when detecting no data transmission.

[0089] In an embodiment of the present application, the first terminal device can send terminal device information to the network device at any time, or the first terminal device can only send terminal device information on a specific frequency resource according to a time interval pre-configured by the network device.

[0090] The terminal device information may also include a request reason, which is used by the network device to analyze the operation of the network device and the terminal device and understand the reason for enabling or disabling the RIS device. In one example, the request reason may be that the downlink received signal quality is below a first threshold, or that the uplink bit error rate is above a second threshold.

[0091] In an embodiment of the present application, a network device may receive terminal device information sent by multiple terminal devices within the service range of a RIS device, and the terminal device information sent by the multiple terminal devices is inconsistent. If the terminal device information of the multiple terminal devices is sent too close in time, when one terminal device requests to turn on the RIS device, another terminal device immediately requests to turn off the RIS device, resulting in frequent switching of the RIS device, which affects the performance of the terminal devices. At the same time, the frequent switching of the RIS device will also consume a lot of energy. In order to reduce the frequent switching of the RIS device, the time interval for the terminal devices to send the terminal device information can be configured so that the multiple terminal devices send the terminal device information at least based on a certain time interval, that is, the time interval for sending the device information is greater than the certain time interval.

[0092] The time interval for the terminal device to send the terminal device information can be pre-configured or updated during the data transmission process.

[0093] In the embodiment of the present application, the network device sends first instruction information to the RIS device to implement remote control of the RIS device by the network device.

[0094] The first indication information may also include the duration of the RIS device's operation. It's understood that a RIS may need to serve multiple terminal devices, so a single terminal device may not be constantly served. The network device will determine the time and duration of service for a terminal device based on the specific RIS's service capacity, or based on the availability of specific services. If a specific duration is undetermined, it can be set to an unlimited duration until a RIS device shutdown indication is received.

[0095] In an embodiment of the present application, a network device detects terminal device information corresponding to a service range of a RIS device, or receives terminal device information sent by a first terminal device located within the service range of the RIS device; and determines, based on the terminal device information, first indication information for instructing the RIS device to turn on or off. By using the first indication information, the RIS device can be flexibly turned on when needed and turned off when not needed, thereby improving data transmission quality and reducing unnecessary resource usage, thereby improving the overall efficiency of the communication system.

[0096] In some embodiments, the terminal device information detected by the network device includes at least one of the following:

[0097] The first information is used to indicate whether a terminal device exists within the service range;

[0098] The second information is used to indicate the number of terminal devices within the service range;

[0099] business information;

[0100] The data transmission requirement information is used to determine whether a terminal device within the service range has a data transmission requirement.

[0101] In an embodiment of the present application, the network device can detect whether there is a terminal device within the service range of the RIS device, the number of terminal devices within the service range of the RIS device, service information corresponding to the services of the terminal devices within the service range of the RIS device, and whether there is a data transmission demand from the terminal devices within the service range of the RIS device.

[0102] The first information is used to indicate whether there is a terminal device within the service range of the RIS device. When the first information indicates that there is a terminal device within the service range, it is determined that the first indication information indicates to turn on the RIS device; when the first information indicates that there is no terminal device within the service range, it is determined that the first indication information indicates to turn off the RIS device.

[0103] The second information is used to indicate the number of terminal devices within the service range of the RIS device. When the second information indicates that the number of terminal devices within the service range is greater than or equal to the first number, it is determined that the first indication information indicates to turn on the RIS device; when the second information indicates that the number of terminal devices within the service range is less than the first number, it is determined that the first indication information indicates to turn off the RIS device.

[0104] The service information is used to indicate the services of the terminal devices within the service range of the RIS device; the first indication information is determined according to the services of the terminal devices within the service range of the RIS device.

[0105] Based on the data transmission requirement information, it can be determined whether a terminal device within the service range has a data transmission requirement. If the terminal device has a data transmission requirement, the first indication information is determined to indicate turning on the RIS device; if the terminal device does not have a data transmission requirement, the first indication information is determined to indicate turning off the RIS device.

[0106] In an embodiment of the present application, the first indication information may be determined by comprehensively considering the first information, the second information, the service information, and the data transmission requirement information. In one example, if the first information indicates that a terminal device exists within the service range, the second information indicates that the number of terminal devices within the service range is less than the first number, the service of the terminal device within the service range indicated by the service information satisfies the first condition, and the data transmission requirement information indicates that the terminal device has a data transmission requirement, the first indication information is determined to indicate that the RIS device is to be enabled.

[0107] In the embodiment of the present application, the specific scheme for determining the first indication information by combining the first information, the second information, the service information and the data transmission requirement information can be determined according to the specific needs in the actual application process, and the present application does not limit this.

[0108] In an embodiment of the present application, by determining at least one of the first information, second information, service information, and data transmission requirement information included in the terminal device information, the network device can more accurately determine the first indication information, so that the network device can implement on-demand switching control of the RIS device.

[0109] In some embodiments, based on Figure 1 The communication method shown in the embodiment of the present application also includes:

[0110] In a case where the terminal device information includes the service information, determining the first indication information according to whether the service information satisfies a first condition;

[0111] The first condition is related to at least one of the following: whether participation of a RIS device is required; and service priority.

[0112] Here, the first condition is that the network device determines whether the service of the terminal device satisfies the rule set for enabling the RIS device based on the service information.

[0113] In the embodiment of the present application, when the service information meets the first condition, the first indication information is determined to indicate that the RIS device is turned on; when the service information does not meet the first condition, the first indication information is determined to indicate that the RIS device is turned off.

[0114] In the embodiment of the present application, the first condition may be related to whether the participation of the RIS device is required. When the service information indicates that the participation of the RIS device is required, the first indication information is determined to indicate that the RIS device is turned on; when the service information indicates that the participation of the RIS device is not required, the first indication information is determined to indicate that the RIS device is turned off.

[0115] In one example, the service of the terminal device may be a device direct connection service, which does not require network device participation during data transmission, that is, does not require a RIS device to improve data transmission quality. Therefore, it may be determined that the first indication information indicates shutting down the RIS device.

[0116] In one example, the service of the terminal device may be a cellular link task, which requires the participation of a network device during data transmission, that is, a RIS device is needed to improve data transmission quality. Therefore, it may be determined that the first indication information indicates to start the RIS device.

[0117] In an embodiment of the present application, the first condition may be related to a service priority. If the priority indicated by the service information satisfies a preset priority condition, the first indication information is determined to indicate that the RIS device should be enabled. If the priority indicated by the service information does not satisfy the priority condition, the first indication information is determined to indicate that the RIS device should be disabled. In one example, there are seven levels of service priority for a terminal device. If the priority of the terminal device is greater than or equal to level 4, the first indication information is determined to indicate that the RIS device should be enabled. If the priority of the terminal device is less than level 4, the first indication information is determined to indicate that the RIS device should be disabled.

[0118] In the embodiment of the present application, when it is determined that the service information does not meet the first condition and the RIS device is in a closed state, the first indication information indicates not to open the RIS device.

[0119] In the embodiment of the present application, by determining whether the RIS device needs to be involved and the service priority indicated by the service information, whether the RIS device needs to be turned on is determined based on the decision dimensions of whether the RIS device needs to be involved and the service priority, the accuracy of the judgment on turning on or off the RIS device is improved, thereby achieving reasonable allocation of network resources.

[0120] In some embodiments, based on Figure 1 The communication method shown in the embodiment of the present application also includes:

[0121] When the data transmission requirement information indicates that the terminal device is in a radio resource control (RRC) connected state and / or the terminal device is in an RRC inactive state with data transmission, determining that the terminal device has a data transmission requirement; and / or,

[0122] When the data transmission requirement information indicates that the terminal device is in an RRC idle state and / or the terminal device is in an RRC inactive state with no data transmission, it is determined that the terminal device has no data transmission requirement.

[0123] Here, Radio Resource Control (RRC) is used to manage the connection status between the terminal device and the network device.

[0124] The RRC connection state indicates that the terminal device has established a communication connection with the network device and is transmitting data or waiting for transmission; in an embodiment of the present application, when the terminal device is in the RRC connection state, it is determined that the terminal device has a data transmission demand.

[0125] The RRC inactive state means that although the terminal device has not yet started data transmission, it has completed some connection configuration and may initiate data transmission soon. When the terminal device is in the inactive state, there may be a small amount of data transmission or no data transmission. Therefore, it is necessary to determine whether the terminal device has data transmission.

[0126] The RRC idle state indicates that the terminal device has not established any connection with the network device and is not ready to perform data transmission, and is in a low power consumption state. In the embodiment of the present application, when the terminal device is in the RRC idle state, it is determined that the terminal device has no data transmission demand.

[0127] In an embodiment of the present application, the network device can determine that the terminal device has a data transmission requirement when the terminal device is in an RRC connected state and / or an RRC inactive state with data transmission; when the terminal device is in an RRC idle state and / or an RRC inactive state with no data transmission, it can determine that the terminal device has no data transmission requirement.

[0128] In the embodiment of the present application, the network device determines whether the terminal device has a data transmission requirement based on the RRC state of the terminal device and whether there is data transmission, so that the RIS device can be dynamically controlled to be turned on or off according to whether the terminal device has a data transmission requirement.

[0129] In some embodiments, based on Figure 1 The communication method shown in the embodiment of the present application also includes:

[0130] receiving terminal device information sent by a second terminal device within a service range of the RIS device;

[0131] In a case where the service priority included in the terminal device information sent by the second terminal device is higher than the service priority included in the terminal device information sent by the first terminal device, the first indication information is determined according to the terminal device information sent by the second terminal device.

[0132] In an embodiment of the present application, the network device may receive terminal device information sent by different terminal devices, and the terminal device information sent by different terminal devices is different. The first indication information is determined based on the terminal device information corresponding to the terminal device with higher service priority.

[0133] In one embodiment, the terminal device information sent by the first terminal device and received by the network device includes a request type of a device startup request, and the terminal device information sent by the second terminal device includes a request type of a device shutdown request. When the service priority corresponding to the service of the first terminal device is higher than the service priority corresponding to the service of the second terminal device, the first indication information is determined to indicate startup of the RIS device based on the terminal device information sent by the first terminal device; when the service priority corresponding to the service of the first terminal device is lower than the service priority corresponding to the service of the second terminal device, the first indication information is determined to indicate shutdown of the RIS device based on the terminal device information sent by the second terminal device.

[0134] In the embodiment of the present application, by comparing the service priorities corresponding to services of different terminal devices, the control requirements of terminal devices corresponding to services with higher service priorities for RIS devices are preferentially met, so that services with higher service priorities can obtain better service quality.

[0135] In some embodiments, the terminal device information received by the network device includes a request type and a service priority;

[0136] The request type includes a device start request or a device shutdown request.

[0137] In an embodiment of the present application, a first terminal device within the RIS service range sends terminal device information to a network device; the terminal device information includes a request type and a service priority; and the network device determines first indication information based on the request type and the service priority.

[0138] In an embodiment of the present application, when the request type is a device activation request and the service priority satisfies the service priority condition, the first indication information is determined to indicate that the RIS device is to be activated; and / or, when the request type is a device activation request and the service priority does not satisfy the service priority condition, the first indication information is determined to indicate that the RIS device is to be activated or not to be activated after a first preset time period.

[0139] In an embodiment of the present application, when the request type is a device shutdown request and the service priority meets the service priority condition, it is determined that the first indication information indicates that the RIS device is to be shut down; and / or when the request type is a device shutdown request and the service priority does not meet the service priority condition, it is determined that the first indication information indicates that the RIS device is to be shut down after a first preset time period or that the RIS device is not to be shut down.

[0140] In the embodiment of the present application, when the request type is a device start request, it is determined that the first indication information indicates to start the RIS device; when the request type is a device shutdown request, it is determined that the first indication information indicates to shut down the RIS device.

[0141] In the embodiment of the present application, by receiving the request type and service priority included in the terminal device information sent by the terminal device according to the network device, the terminal device's demand for turning on or off the RIS device can be better met, thereby reasonably controlling the turning on or off of the RIS device, improving the utilization efficiency of the RIS device, and reducing unnecessary resource occupation.

[0142] In some embodiments, based on Figure 1 The communication method shown in the embodiment of the present application further includes: sending response information to the first terminal device, where the response information is used to instruct to turn on or off the RIS device.

[0143] Accordingly, based on Figure 2 The communication method shown, the communication method provided in the embodiment of the present application also includes: receiving response information sent by the network device.

[0144] In an embodiment of the present application, the network device determines first indication information based on the terminal device information sent by the first terminal device, and sends the first indication information to the RIS device. After determining whether to turn on or off the RIS device based on the first indication information, the network device sends response information to the first terminal device in response to the terminal device information sent by the first terminal device. The response information may include turning on or off the RIS device.

[0145] In the embodiment of the present application, the network device may send response information to all terminal devices within the service range of the RIS device, or may send response information only to the terminal device that sent the terminal device information.

[0146] In the embodiment of the present application, the network device sends a response message to the first terminal device to synchronize the on or off status of the RIS device with the first terminal device, so that the first terminal device performs a corresponding operation according to the response message.

[0147] In some embodiments, based on Figure 1 The communication method shown, the communication method provided by the embodiment of the present application further includes: broadcasting the service information of the RIS device.

[0148] Accordingly, based on Figure 2 The communication method shown, the communication method provided by the embodiment of the present application further includes: receiving service information of the RIS device broadcast by the network device.

[0149] Here, the service information of the RIS device includes location information, service mode, and device identification.

[0150] The location information may be a GPS location, or distance and angle information from the network device.

[0151] The service mode may include whether the RIS device can be turned on or off on demand, the time period during which the RIS device can be controlled or not, etc. The controllable / uncontrollable time period refers to the time period during which the RIS device can be controlled to be turned on or off, and the time period during which the RIS device cannot be controlled to be turned on or off.

[0152] In the embodiment of the present application, the controllable / uncontrollable time periods of the RIS devices in the same cell may be consistent, or different controllable / uncontrollable time periods may be configured for each RIS device.

[0153] In the embodiment of the present application, the service information of the RIS device may further include the activation status and service range of the RIS device.

[0154] In the embodiment of the present application, the network device periodically broadcasts the service information of the RIS device.

[0155] In the embodiment of the present application, by broadcasting the service information of the RIS device, the terminal device can timely learn about the available RIS resources, so that the first terminal device can send the terminal device information to the network device according to the service information of the RIS device.

[0156] In some embodiments, sending terminal device information to a network device based on the location information and service requirements of the first terminal device in S201 includes: sending the terminal device information to the network device based on the location information and service requirements of the first terminal device in a first time period; the first time period is determined based on service information of a RIS device received from the network device.

[0157] In the embodiment of the present application, the service information of the RIS device includes the controllable / uncontrollable time period of the RIS device as the first time period. The first terminal device sends terminal device information to the network device according to the location information and service requirements of the first terminal device in the first time period.

[0158] In the embodiment of the present application, the first terminal device determines to send the terminal device information in a specific first time period based on the service information of the RIS device, so that the terminal device only initiates the relevant request when the RIS device is available, which can reduce the signaling burden caused by invalid requests and further improve the overall operation efficiency of the communication system.

[0159] The following describes the application of the embodiments of the present application in actual scenarios.

[0160] Reconfigurable smart surfaces (RIS) integrate a large number of low-cost passive reflective elements on a single surface. Through real-time parameter configuration, they intelligently change the signal's reflected amplitude and / or phase, thereby reconfiguring the wireless propagation environment. This collaboratively achieves directional signal enhancement and significantly improves the performance of wireless communication networks. RIS devices can be turned on and off under the control of network equipment.

[0161] In actual network applications, RIS devices assisting communication is sometimes necessary, but sometimes unnecessary or not urgent:

[0162] In one example, when a user is at the cell edge or is blocked, resulting in a weak received signal, or is subject to strong interference, a RIS device is needed to assist communication, enhance the received signal strength, or avoid strong interference;

[0163] In one example, when the user's received signal can meet the reception strength requirement (considering the current service demand) and the delay sensitivity requirement is high, there is little need for a RIS device to assist in communication.

[0164] Based on the above description, this application proposes an adaptive RIS network performance enhancement method.

[0165] Network devices are configured with RIS devices that can be turned on or off in some areas, such as Figure 4 As shown, multiple RIS devices are deployed within the coverage of the network device, and each RIS device has a certain service range; the terminal device can detect that it has entered the service range of a certain RIS device, or the network device is able to sense that the terminal device has entered the service range of a certain RIS device.

[0166] In the embodiments of the present application, the following three solutions are proposed for controlling RIS devices:

[0167] Solution 1: The network device continuously or periodically detects users within the service range of the RIS device and decides whether to enable or disable the RIS device based on the detected terminal device information. This can include the following situations:

[0168] (1) The base station turns on the RIS device as soon as it detects any user within the service range of the RIS device, and turns off the RIS device if there is no user.

[0169] (2) Whether to enable the RIS device is determined based on the actual number of users within the service range of the RIS device detected within a certain period of time (corresponding to the number of devices in the aforementioned embodiment). In one example, when the actual number of users detected is greater than a first number, the RIS device is enabled; when the actual number of users detected is not greater than the first number, the RIS device is disabled.

[0170] (3) Determine whether to enable the RIS device based on the user's wireless link service type. In one example, when the user's wireless link service type is a device-to-device (D2D) service, the RIS device is disabled; when the user's wireless link service type is a cellular link service, the RIS device is enabled.

[0171] (4) The network device determines whether to enable the RIS device based on the detected service priority of the user. In one example, the service priority of the user has 7 levels. When the service priority is higher than level 4, the RIS device is enabled. When the service priority is lower than level 4, the RIS device is disabled.

[0172] Solution 2: The base station detects users within the service range of the RIS device and controls the RIS device to be turned on or off according to the RRC status (idle, inactive, and connected) of users within the service range of the RIS device.

[0173] When a user within the service range of the RIS device is in an RRC idle state (RRC idle), the RIS device is determined to be shut down; when a user within the service range of the RIS device is in an RRC inactive state (RRC inactive) and there is no data transmission, the RIS device is determined to be shut down.

[0174] When a user within the service range of the RIS device is in an RRC connected state (RRC connected), the RIS device is determined to be turned on; when a user within the service range of the RIS device is in an RRC inactive state and has data transmission requirements or is configured with related computer graphics (CG) resources, the RIS device is determined to be turned on.

[0175] Solution 3: The network device announces the location information, service scope, service mode, and activation status of the RIS device in the cell. The relevant UE will send a request to the network device to activate or deactivate the RIS device (corresponding to the terminal device information in the aforementioned embodiment) based on its own location information and actual service status (for example, the service the user is running is a high-speed service).

[0176] The location information and service mode of the RIS device are periodically published in the system broadcast message, which also contains the ID information of the RIS device.

[0177] The location information of the RIS device may be a GPS location, or distance and angle information of the RIS device relative to a base station, or predefined known geographical area division information.

[0178] The service mode of a RIS device includes whether it can be turned on and off on demand, and the time periods during which the RIS device is controllable or uncontrollable. The controllable / uncontrollable time periods for a RIS device refer to whether the RIS can be turned on and off during these time periods. The specific control of the controllable / uncontrollable time periods for a RIS device can be the same for all RIS devices configured in a cell. In one example, the controllable / uncontrollable time periods for RIS#1-10 in a cell are the same. Alternatively, different RIS devices in a cell can have different service modes. In one example, the uncontrollable time period for RIS#1 is from Radio Frames 1 to 10, the uncontrollable time period for RIS#2 is from Radio Frames 2 to 5, and so on.

[0179] In an embodiment of the present application, a user may send a RIS device on / off request to the base station at any time, or the user may only send a request to turn on or off the RIS device on a specific frequency resource at a predefined time interval, wherein the resource for sending the request to turn on or off the RIS device may be indicated by the base station; the RIS device on / off request sent by the user may carry the request reason (Cause) and the current service priority.

[0180] In the embodiment of the present application, the user can send a request to the network device to start the RIS device when there is data transmission; and send a request to the network device to shut down the RIS device when there is no data transmission.

[0181] In an embodiment of the present application, if different users within the service range of the same RIS device send different requests to turn on and off the RIS device, the service request of the user with higher service priority is executed first. In one example, when a high-priority user sends a request to turn off the RIS device and a low-priority user sends a request to turn on the RIS device, the network device determines to turn off the RIS device because turning on the RIS device may interfere with the high-priority user.

[0182] In this embodiment of the present application, the time interval between user requests can be configured to prevent frequent powering on and off of the RIS device caused by requests from different users. It is understood that the powering on and off of the RIS device by a user's request is implemented based on resources configured on the network device. If the resources configured by different users are too close in time, one user may just request to power on the RIS device while another user may soon request to power it off. This will cause the RIS device to frequently power on and off, impacting user performance and consuming significant energy.

[0183] The embodiment of the present application provides a signaling implementation method for a user to request the RIS device to be turned on or off, such as Figure 5 As shown, the following steps S501 to S506 may be included:

[0184] Step S501: The network device determines the location and service mode of the RIS device;

[0185] Step S502: The network device broadcasts the location and service mode of the RIS device in the local cell;

[0186] Step S503: User A sends terminal device information to the network device to request to turn on or off RIS device A;

[0187] The terminal device information may include the request type, request reason and service priority; wherein the request type includes device startup request and device shutdown request; the request reason may be that the downlink received signal quality is lower than a first threshold, or the uplink bit error rate is higher than a second threshold.

[0188] Step S504: The network device determines whether to enable RIS device A;

[0189] The network device determines whether to enable the RIS device A according to the request type and service priority included in the received terminal device information.

[0190] In an embodiment of the present application, when the request type is a device activation request and the service priority satisfies the service priority condition, the first indication information is determined to indicate that the RIS device is to be activated; and / or, when the request type is a device activation request and the service priority does not satisfy the service priority condition, the first indication information is determined to indicate that the RIS device is to be activated or not to be activated after a first preset time period.

[0191] In an embodiment of the present application, when the request type is a device shutdown request and the service priority meets the service priority condition, it is determined that the first indication information indicates that the RIS device is to be shut down; and / or when the request type is a device shutdown request and the service priority does not meet the service priority condition, it is determined that the first indication information indicates that the RIS device is to be shut down after a first preset time period or that the RIS device is not to be shut down.

[0192] Step S505: The network device sends first instruction information to the RIS device A;

[0193] The first instruction information may include turning on or off the RIS device A, and the length of time it lasts.

[0194] Step S506: The network device sends a message to user A indicating that RIS device A has been turned on.

[0195] The embodiment of the present application provides a signaling implementation method for multiple users to request the opening or closing of a RIS device, such as Figure 6 As shown, the following steps S601 to S608 may be included:

[0196] Step S601: User B sends terminal device information to the network device to request to enable RIS device A;

[0197] Step S602: The network device determines that the service priority is lower than the priority condition based on the terminal device information sent by user B;

[0198] Step S603: The network device sends a message to user B to delay opening of RIS device A;

[0199] Step S604: User A sends terminal device information to the network device to request to enable RIS device A;

[0200] The service priority included in the terminal device information sent by user A is the highest priority.

[0201] Step S605: The network device determines that the service priority is higher than the service priority condition based on the terminal device information sent by user A;

[0202] Step S606: The network device sends first instruction information to the RIS device, instructing to start the RIS device A;

[0203] Step S607: The network device sends a message to user B that RIS device A has been turned on;

[0204] Step S608: The network device sends a message to user A that RIS device A has been turned on.
