[0004] Reconfigurable Intelligent Surfaces (RIS) and Smart Repeaters are key technologies in 5.5G and 6G. RIS technology utilizes artificial electromagnetic materials with programmable electromagnetic properties.

In the millimeter wave field, this method can flexibly adjust the beam direction and coverage, enabling full application of millimeter waves in complex scenarios.

[0005] However, in actual applications, RIS is mostly deployed and maintained manually. When the deployment status of RIS is abnormal, especially when the panel posture is abnormal, it is difficult to detect the abnormality in time, resulting in poor current network performance and affecting the communication quality of user devices.

[0022] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0023] FIG1 is a flow chart of an abnormal state handling method provided in an embodiment of the present application. The method is applied to a first node, where the first node can be a smart metasurface RIS or a smart repeater. The present embodiment is described using the smart metasurface RIS as an example. As shown in the figure, the abnormal state handling method 100 includes the following steps:

[0024] Step S101: Acquire abnormal status information of the first node.

[0025] Step S102: determining target information based on the abnormal state information and a pre-stored candidate codebook set, and sending the target information to the second node.

[0026] The target information includes abnormal state information and an activation codebook of the first node.

[0027] In a specific implementation, as shown in FIG2 , the first node RIS / Smart Repeater includes a controller, a sensor, and a panel; wherein the controller includes but is not limited to a communication module, a computing module, a storage module, and other modules, which are used for calculation of the RIS or Smart Repeater, storage of interface information with other components, and communication functions with the second node; the sensors include but are not limited to a tilt sensor, a gyroscope, and a magnetometer, etc.

[0028] The RIS controller can obtain abnormal status information of its own panel through the configured sensors; determine the target information based on the abnormal status information and the pre-stored alternative codebook set, and send the target information to the second node, wherein the abnormal status information is used to characterize the information of the abnormal posture of the RIS panel, the alternative codebook set includes multiple alternative codebooks, and the alternative codebook is used to characterize the status information of the first node. In the standard protocol, "codebook" can also be called "beam indication" or "control word", for example: relay beam indication: the control word of the reflective antenna array of RIS-Fwd (also called the control codebook of the reflective antenna array, referred to as codebook for short), each codebook represents a relative relationship between an incident beam and an outgoing beam, therefore, for the reflective array, a codebook can be called a relay beam indication.

[0029] Through the above steps, when the first node obtains the abnormal state information, it determines the target information based on the abnormal state information and the alternative code book set, and sends the target information to the second node. In this way, the second node can promptly discover that the posture state of the first node is abnormal and perform corresponding processing to avoid a serious decline in network performance and ensure the stability of the communication quality of the user equipment.

[0030] Furthermore, the first node can also quickly recover a normal working state through the alternative codebook set, ensuring normal communication with the second node without affecting the current network coverage and service conditions.

[0031] In a possible implementation, in step S101, obtaining abnormal status information of the first node includes:

[0032] Step 1011: Acquire first status information collected by a sensor configured on the first node.

[0033] Step 1012: When the deviation between the first state information and the pre-stored configuration information is greater than a preset threshold, an information collection instruction is sent to the sensor; the information collection instruction is used to control the sensor to collect the second state information of the intelligent metasurface device at a preset time interval.

[0034] Step 1013: Determine abnormal status information of the first node based on the multiple pieces of second status information corresponding to the information collection instruction and the configuration information.

[0035] In a specific implementation, first, first state information of the RIS is obtained. This first state information can be attitude information of the RIS panel, for example, the panel's horizontal tilt angle α and vertical tilt angle β. In practical applications, this attitude information can be obtained by installing a tilt sensor on the panel's rotation axis, or by installing a gyroscope and magnetometer.

[0036] The RIS controller sets the acquisition interval t, typically set to a specific time, such as 5 or 10 seconds, based on actual needs. The controller acquires the RIS panel's attitude information from the sensor every t seconds and compares it with the current panel configuration information pre-stored by the RIS controller. The RIS panel configuration information is the attitude parameters pre-configured by the base station based on coverage conditions.

[0037] In this way, the attitude information reported by the sensor at intervals of t is the measurement information. The RIS controller compares the difference in the measurement information at intervals of t. If the deviation between the attitude information and the configuration information is greater than a preset threshold, it is considered that a panel attitude anomaly has occurred. It should be noted that the deviation between the attitude information and the configuration information can be the difference between the attitude information and the configuration information, or the ratio between the attitude information and the configuration information.

[0038] When the RIS controller detects that the RIS panel has an abnormal posture, it sends an information collection instruction to the sensor to control the sensor to quickly measure the second state information of the first node n times according to a preset time interval s, where the preset time interval s is less than the collection time interval t.

[0039] Based on the multiple second state information and configuration information, the abnormal state information of the first node is determined. For example, the difference between the average of n measurement results and the configuration angle is determined as the abnormal angle deviation of the RIS panel, such as the pitch angle deviation Δθ, the azimuth angle deviation The abnormal status information of RIS is determined based on the angle deviation. In this way, the measurement results can be prevented from being affected by external factors and the reliability of the abnormal status information can be ensured.

[0040] In the above step S102, the target information is determined based on the abnormal state information and the pre-stored candidate codebook set, including the following two cases:

[0041] A first possible scenario: when there is a target codebook matching the abnormal state information among multiple candidate codebooks in the candidate codebook set, the active codebook of the first node includes the target codebook.

[0042] A second possible situation: when there is no target codebook matching the abnormal state information among the multiple candidate codebooks in the candidate codebook set, the active codebook of the first node includes the codebook currently corresponding to the first node.

[0043] In a specific implementation, each candidate codebook in the candidate codebook set may be identified according to an angle, and its representation is as follows:

[0044] Among them, φ k represents the kth candidate codebook in the candidate codebook set; θAoA represents the incident pitch angle of the RIS panel; represents the incident azimuth angle of the RIS panel; θ AoD represents the exit elevation angle of the RIS panel; represents the emission azimuth of the RIS panel.

[0045] The panel pitch angle deviation Δθ and azimuth angle deviation measured according to the above method are Query whether there is a codebook content in the candidate codebook set that satisfies the unchanged AoD of the second node and the unchanged coverage area of ​​the RIS panel. The codebook to be queried is:

[0046] If there is a corresponding candidate codebook, this codebook is replaced with the active codebook of the current RIS panel. If there is no corresponding candidate codebook, no replacement is performed and the codebook currently corresponding to the RIS is determined as the active codebook.

[0047] In this way, after determining the target information, the first node can quickly return to normal and communicate normally with the second node, and then send the target information to the second node so that the second node can promptly detect the abnormality of the posture state of the first node and perform corresponding processing.

[0048] In a possible implementation, in step S102, sending the target information to the second node includes: carrying the target information into abnormal state feedback signaling based on signaling configuration information sent by the second node; and sending the abnormal state feedback signaling to the second node.

[0049] In a specific implementation, as shown in FIG3 , the second node (base station) issues signaling configuration information for the first node RIS to report target information. Then, the first node (RIS controller) carries the target information into the abnormal state feedback signaling based on the signaling configuration information to report the abnormal state.

[0050] The following content is added to the signaling configuration information:

[0051] RIS-Abnormal-config defines the RIS abnormality reporting configuration, including whether to report an abnormality and the waiting time after an abnormality is reported. AbnormalCategory indicates whether abnormality reporting is configured. RequestProhibitTimer indicates the waiting time after an abnormality is reported. After RIS reports an abnormality, this timer starts. No abnormality will be reported during the timer. s0, s1, and s2 indicate the configured time intervals.

[0052] Since the target information includes abnormal status information and the activation codebook, the following information elements are added to the abnormal status feedback signaling:

[0053] RIS-Abnormal-information is defined as abnormal information reported by RIS, including activation codebook information, pitch angle offset, and azimuth angle offset.

[0054] ActiveCodeBook: indicates the angle information of the currently activated codebook, which is indicated in the form of 4 angles, where each angle is indicated according to AngleIndication.

[0055] HorizontalAngleDeviation: Indicates the offset of the panel's pitch angle. The value range can be configured according to actual conditions.

[0056] VerticalAngleDeviation: Indicates the offset of the panel's azimuth angle. The value range can be configured according to actual conditions.

[0057] In a possible implementation, in the above step S102 , after sending the target information to the second node, the abnormal state processing method 100 further includes: updating the candidate codebook set based on the codebook set sent by the second node.

[0058] In a specific implementation, after the first node sends the target information, the second node detects that the first node's sending posture is abnormal, processes the target information accordingly, obtains a codebook set, and sends the codebook set to the first node. The first node updates the stored candidate codebook set based on the codebook set sent by the second node.

[0059] In this way, by updating the candidate codebook set of the first node, the validity of the target information can be ensured, thereby facilitating improved efficiency in handling abnormal conditions.

[0060] In one possible implementation, the codebook set is determined based on target state information and a preconfigured fluctuation increment; wherein the target state information is state information of the first node indicated by the activated codebook in the target information, and the fluctuation increment is determined by the storage capacity of the first node.

[0061] In a specific implementation, when configuring the RIS candidate codebooks, the second node (base station) configures the candidate codebook set based on the currently calculated optimal codebook and the panel angle fluctuation ±ω. The value of ω can be determined based on long-term statistical results of RIS panel offset, or it can be configured as a preset value and determined based on the range reported by the RIS later.

[0062] After determining the value of ω, the codebook granularity within ±ω is determined based on the storage capacity of the RIS controller. If ω is large, the codebook set granularity is also large; if ω is small, the codebook set granularity can also be configured to be smaller. For example, when ω is 3°, the codebook set is configured at 0.5° intervals; when ω is 10°, the codebook set is configured at 1° intervals.

[0063] The present invention provides an abnormal state processing method, which is applied to a first node and obtains abnormal state information of the first node; determines target information based on the abnormal state information and a pre-stored set of candidate codebooks; and transmits the target information to a second node. This method enables the second node to promptly detect abnormalities in the posture state of the first node and perform corresponding processing to avoid a serious degradation in network performance and ensure the stability of communication quality of user devices.

[0064] FIG4 shows another flow diagram of the abnormal state handling method provided in an embodiment of the present application. The method is applied to a second node, where the second node can be a 5G low-frequency base station, a 5G millimeter wave base station, or a base station suitable for 6G. In the embodiment of the present application, the execution subject is a base station as an example. As shown in the figure, the abnormal state handling method 400 includes the following steps:

[0065] Step S401: the second node obtains target information sent by the first node, where the target information includes abnormal state information and an activation codebook of the first node.

[0066] Step S402: When the abnormal state information meets a preset condition, determine a codebook set to be sent to the first node based on the target information; the codebook set includes multiple codebooks, and the codebooks are used to represent the state information of the first node.

[0067] Through the above steps, the second node obtains the target information sent by the first node; when the abnormal state information meets the preset conditions, the second node determines the codebook set to be sent to the first node based on the target information. In this way, the second node can promptly detect the abnormal state of the first node and update the first node's candidate codebook set to ensure the validity of the target information, thereby improving the efficiency of abnormal state processing.

[0068] In a possible implementation, in the above step S402, after determining the codebook set to be sent to the first node based on the target information, the abnormal state processing method 400 further includes: obtaining a signal quality measurement indicator of a signal received by a target user equipment; the target user equipment is a user equipment within the coverage range of the network formed by the first node; and when the signal quality measurement indicator is lower than a preset indicator threshold, issuing an alarm message.

[0069] Among them, signal quality measurement indicators include but are not limited to reference signal received power (RSRP), signal to interference plus noise ratio (SINR), etc.; the preset indicator threshold can be a fixed value set according to actual needs, or it can be a historical signal quality measurement indicator before the target information is reported, and is not specifically limited here.

[0070] Let's take a look at a specific example. As shown in FIG5 , the abnormal state processing method may include the following steps:

[0071] Step 501: The base station calculates a candidate codebook set based on the predetermined angle of the RIS panel deployment at ±5°, so that the coverage range of the RIS remains unchanged, and sends the candidate codebook set to the RIS controller.

[0072] Step 502: The base station side configures the following content in the Radio Resource Control (RRC) signaling to instruct the RIS to perform abnormality adaptive processing, and after the abnormality is triggered, the interval for reporting the abnormality is 5 seconds.

[0073] Step 503: The RIS panel monitors the panel attitude using the configured sensors. During the monitoring process, an abnormal phenomenon of a 3° deviation in the panel elevation angle is found.

[0074] Step 504: The RIS controller queries the candidate codebook set configured on the base station side based on the magnitude of the elevation angle offset and finds that there is a codebook in the codebook set that satisfies the elevation angle offset of 3°:

[0075] Step 505: RIS reports the panel abnormality through the following information cells and starts the Request Prohibit Timer. It will not report again within 5 seconds.

[0076] Step 506: The base station updates the pre-stored panel attitude information of the RIS panel according to the 3° elevation offset angle, recalculates the codebook set, and sends it to the RIS controller.

[0077] Step 507: The base station performs measurement on the user equipment (UE) covered by the RIS. If it is determined that the current coverage condition meets the conditions, the exception handling is completed.

[0078] In a possible implementation, in the above step S401, before the second node obtains the target information sent by the first node, the abnormal state processing method 400 further includes:

[0079] The second node sends signaling configuration information to the first node;

[0080] The target information sent by the first node is determined based on the abnormal state feedback signaling sent by the first node corresponding to the signaling configuration information.

[0081] The following is explained with reference to a specific example. As shown in FIG6 , the abnormal state processing method may include the following steps:

[0082] Step 601: The base station calculates a candidate codebook set based on the predetermined angle of the RIS panel deployment, within ±3°, to ensure that the AoD of the current base station remains unchanged and the coverage of the RIS remains unchanged. The candidate codebook set is then sent to the RIS controller.

[0083] Step 602: The base station configures the following content in the RRC signaling to instruct the RIS to perform abnormal adaptive processing, and after the abnormality is triggered, the interval for reporting the abnormality is 6 seconds;

[0084] Step 603: The RIS panel monitors the status of the panel posture according to the configured sensors. No abnormality of the panel posture is found during the monitoring process.

[0085] In a possible implementation, the abnormal state processing method 400 further includes: issuing an alarm message when the abnormal state information does not meet the preset condition.

[0086] The following is explained with reference to a specific example. As shown in FIG7 , the abnormal state processing method may include the following steps:

[0087] Step 701: The base station calculates a candidate codebook set based on the predetermined angle of the RIS panel deployment, within ±5°, to ensure that the current base station's AoD remains unchanged and the RIS coverage remains unchanged. The candidate codebook set is then sent to the RIS controller.

[0088] Step 702: The base station side configures the following content in the RRC signaling to instruct the RIS to perform abnormal adaptive processing, and after the abnormality is triggered, the interval for reporting the abnormality is 10 seconds.

[0089] Step 703: The RIS panel monitors the panel attitude using the configured sensors. During the monitoring process, an abnormal phenomenon of the panel elevation angle being offset by 15° is discovered.

[0090] Step 704: The RIS controller queries the candidate codebook set configured on the base station side according to the magnitude of the elevation angle offset, and finds that there is no codebook in the codebook set that satisfies the elevation angle offset of 15°.

[0091] Step 705: RIS reports the panel abnormality through the following information element. The codebook reported at this time is the currently activated codebook, and RequestProhibitTimer is started. No repeated reporting will be performed within 5 seconds.

[0092] Step 706: The base station determines that the RIS panel offset is too large based on the 15° elevation offset angle and issues an alarm.

[0093] In a possible implementation, in step S402, determining the codebook set to be sent to the first node based on the target information includes:

[0094] Obtain target state information of a first node indicated by an activated codebook in the target information; determine a codebook set to be sent to the first node based on the target state information and a pre-configured fluctuation increment; the fluctuation increment is determined by a storage capacity of the first node.

[0095] In a specific implementation, as shown in FIG8 , the abnormal state processing method may include the following steps:

[0096] Step 801: RIS reports the panel abnormality through the following information element and starts the RequestProhibitTimer, which will not report it repeatedly within 5 seconds.

[0097] Step 802: The base station updates the pre-stored RIS panel attitude information based on the 3° elevation offset. When calculating the updated codebook, the base station performs incremental processing on the existing RIS codebook based on the panel offset. This means that the codebook is not recalculated. Instead, the base station calculates the phase difference of the panel array after the offset based on the existing codebook and the offset, and then directly modifies the currently stored codebook set, reducing the computational complexity of the codebook calculation.

[0098] Step 803: The base station sends the new codebook set to the RIS, and performs measurements through the UE covered by the RIS to determine whether the current coverage meets the conditions, and the exception handling is completed.

[0099] The present application also provides an abnormal state handling method, which is applied to a second node. The second node obtains target information sent by the first node, which includes the abnormal state information and the first node's activated codebook. If the abnormal state information meets preset conditions, the second node determines the codebook set to be sent to the first node based on the target information. In this way, the second node can promptly detect the abnormal state of the first node and update the first node's alternative codebook set to ensure the validity of the target information, thereby improving the efficiency of abnormal state handling.
