[0032] Next, the technical solutions in the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0033] It should be noted that in the present disclosure, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present disclosure should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0034] Hereinafter, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0035] In the description of the present disclosure, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. "And / or" herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0036] With the explosive growth of data traffic, millimeter wave (mmWave) has become a key technology for the fifth-generation mobile communication by virtue of its abundant available frequency bands. The first severe challenge in realizing mmWave communication is path loss. To compensate for the severe path loss in mmWave transmission, mmWave base stations (BSs) usually adopt large-scale antenna arrays for narrow-beam transmission, which can effectively concentrate the transmission energy in a region or direction. However, the directional transmission of mmWave is very sensitive to blockages and may even cause connection interruptions, which also poses new challenges to the establishment and maintenance of mmWave links. For this reason, relay reflection devices such as RIS and NCR are integrated into mmWave cellular systems.

[0037] Relay reflection devices such as RIS / NCR are artificial electromagnetic materials with programmable electromagnetic characteristics, including a large number of low-cost reflective elements. By controlling the phase and amplitude of each element, the focusing direction of the outgoing beam can be adjusted, thereby changing the propagation path of electromagnetic waves and realizing the control of the wireless network environment. Traditional wireless technologies generally perform signal processing at the transceiver to adapt to the dynamic and uncontrollable wireless network environment, while RIS / NCR can actively correct the wireless channel through controllable intelligent signal reflection technology. Therefore, RIS / NCR provides a new degree of freedom for further improving the performance of wireless links and paves the way for the realization of an intelligent programmable wireless environment.

[0038] In mmWave cellular systems, the blockage problem of wireless links caused by factors such as terrain and ground objects will seriously reduce the communication quality and even cause link interruptions. RIS / NCR has the potential to become a new method for dealing with the blockage problem of mmWave communication by virtue of its ability to change the electromagnetic wave transmission environment. In the case where the wireless link between the user equipment and the base station is blocked, the phase adjustment of RIC / NCR can be used to enable the transmission path of electromagnetic waves to bypass the obstacle and reach the user, thereby improving the communication quality and the coverage ability of the mmWave system.

[0039] It can be seen that, as a controllable network device, RIS and NCR have certain mobile terminal attributes, but the content of their controlled characteristics is different from that of mobile terminals. RIS and NCR require higher control robustness and working reliability, and can support stable and high-quality coverage of mobile terminals. To achieve this goal, the network side needs to perform real-time management according to the working status of RIS / NCR. However, there is a lack of technical solutions for managing the status of wireless relay devices in related technologies.

[0040] In view of the above technical problems, the embodiments of the present disclosure provide an exception handling method. The idea is that the first node determines a processing strategy for handling the abnormal state of the wireless relay device and sends the processing strategy to the wireless relay device. Correspondingly, the wireless relay device receives the processing strategy sent by the first node for handling the abnormal state of the wireless relay device. In this way, the wireless relay device can perform real-time management of its own working state. For example, when the wireless relay device appears in an abnormal state, it can perform self-processing according to the processing strategy, which can improve the control robustness and working reliability of the wireless relay device to achieve stable and high-quality coverage of mobile terminals.

[0041] The communication system provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings of the specification.

[0042] See Figure 1 , which is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. As Figure 1 shown, the communication system includes: a base station 110, a wireless relay device 120, and a terminal device 130.

[0043] The first node 110 is used for transmitting and receiving electromagnetic waves.

[0044] Exemplarily, the base station 110 may be a next-generation base station (gNB).

[0045] In some embodiments, as Figure 2 shown, the base station 110 includes: a controller 111 and an antenna 112. Among them, the controller 111 is used for managing the wireless communication interface and wireless channels. The antenna 112 is used for transmitting and receiving electromagnetic waves.

[0046] Exemplarily, the antenna 112 may transmit electromagnetic waves to the wireless relay device 120 under the control of the controller 111.

[0047] In some embodiments, the base station 110 may further include a communication interface 113 for information interaction with other devices. Exemplarily, the base station 110 may perform information interaction with the wireless relay device 120 through the communication interface 113. The base station 110 may also perform information interaction with other devices such as a network server through the communication interface 113.

[0048] In some embodiments, the base station 110 may further include a memory 114 for storing data. Exemplarily, the memory 114 may be used to store a codebook.

[0049] Exemplarily, the memory 114 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a magnetic disk storage medium, or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

[0050] The wireless relay device 120 is used to relay or forward the electromagnetic waves transmitted by the base station 110.

[0051] Exemplarily, the wireless relay device 120 may be a RIS, an NCR, an intelligent relay device, or other devices with signal forwarding and relaying functions.

[0052] In some embodiments, as Figure 3 shown, the wireless relay device 120 includes: a wireless signal relay module (RIS-Forwarding, RIS-Fwd) 121 and a control module (RIS-Mobile-Termination, RIS-MT) 122.

[0053] The wireless signal relay module 121, an antenna reflection array composed of antenna elements, is used to adjust the incident beam in different ways according to the codebooks of different antenna elements (the codebooks are used to implement the control of the spectrum, phase, amplitude, and polarization values of each antenna element), so that the outgoing beam can achieve changes in different amplitudes, different widths, different frequency shifts, and different outgoing angles, as well as changes such as single-beam reflection, multi-beam reflection, diffuse scattering, refraction, and transmission.

[0054] Exemplarily, the wireless signal relay module 121 can reflect the incident beam to a specified area (such as the blind area of the base station's coverage) according to the beam indication (i.e., codebook) provided by the control module 122 to serve the UEs in this area. For example, in the embodiments of the present application, the wireless signal relay module 121 can adjust the incident beam from the base station 110 to the outgoing beam towards the terminal device 130.

[0055] The control module 122 includes a controller 122-1, a memory 122-2, and a communication interface 122-3.

[0056] The controller 122-1 is configured to transmit the relay beam indication (i.e., codebook) to the wireless signal relay module 121 and control the working state of the wireless signal relay module 121.

[0057] Exemplarily, the controller 122-1 can control the working state of the wireless signal relay module 121 according to the indication of the base station 110, such as: switch state (controlling the working or non-working of the wireless signal relay module 121, etc.); power control (controlling the amplitude of the reflected beam of the wireless signal relay module 121); relay beam indication (the codebook of the antenna elements of the wireless signal relay module 121).

[0058] It can be understood that a codebook represents a relative relationship between an incident beam and an outgoing beam. Therefore, for a reflection array, a codebook can also be referred to as a beam indication.

[0059] The memory 122-2 is used to store the codebook.

[0060] The communication interface 122-3 is used for information interaction with other devices. Exemplarily, the control module 122 can perform information interaction with the base station 110 through the communication interface 122-3.

[0061] Exemplarily, the control module 122 can receive the control information (such as codebook update information, etc.) sent by the base station 110 through the communication interface 122-3, and send the working state information of the RIS, the configuration information of the RIS, and the codebook set of the RIS to the base station through the communication interface 122-3.

[0062] Exemplarily, the communication interface 122-3 can perform information interaction with other devices through Narrow Band Internet of Things (NB-IoT), 5th-generation mobile communication technology (5G), wireless fidelity (WiFi), etc.

[0063] A terminal device 130 for communicating based on electromagnetic waves radiated by a wireless relay device 120.

[0064] Exemplarily, the terminal device 130 may be a UE, such as a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, as well as a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) / virtual reality (VR) device, etc. The embodiments of the present application do not impose special restrictions on the specific form of the terminal device 130.

[0065] In some embodiments, the above communication system further includes: a management entity of the wireless relay device, for managing the codebook library of the wireless relay device, the deployment information of the wireless relay device, and the authentication of the wireless relay device, etc. The management entity of the wireless relay device may be deployed in: a base station, a core network domain, a core network element, an operation administration and maintenance (OAM) background, a radio access network (RAN) access network domain, etc. Exemplarily, the above core network element may be: an access and mobility management function (AMF), a service management function (SMF), a centralized coordination function (PCF), a user port function (UPF), an application function (AF), etc.

[0066] It can be understood that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and service scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0067] The following specifically introduces the exception handling method provided by the embodiments of the present disclosure.

[0068] The present disclosure provides an exception handling method, such asFigure 4 As shown, the method includes the following steps:

[0069] S201. The first node determines a processing strategy for handling the abnormal state of the wireless relay device.

[0070] Wherein, the first node may be a network-side node. For example, the first node includes any one of the following: an access network device, a core network device, a management entity of the wireless relay device.

[0071] In some embodiments, the abnormal state of the wireless relay device includes the following situations:

[0101] Abnormal state 3: There is an abnormal connection between the control module of the wireless relay device and the second node.

[0102] Among them, the second node may be a network - side node. For example, the second node may include any one of the following: an access network device, a core network device, and a management entity of a wireless relay device. It can be understood that the first node and the second node are different nodes. For example, when the first node is an access network device, the second node may be a core network device or a management entity of a wireless relay device.

[0103] In some embodiments, the connection anomaly between the control module and the second node includes at least one of the following:

[0104] The failure of the control information or management policy sent by the second node to the control module; among them, the management policy may include a processing policy for handling the abnormal state of the wireless relay device.

[0105] The failure of the status information sent by the control module to the second node.

[0106] Abnormal state 4, the control module or the wireless signal relay module is abnormal.

[0107] In some embodiments, the control - module anomaly includes at least one of the following:

[0108] The standby voltage or standby power consumption exceeds the fifth preset threshold;

[0120] The remaining power or remaining working time is lower than the fourteenth preset threshold;

[0121] One or more of the power-on time, power-off time, and standby operation time of the wireless signal relay module do not conform to the preset time schedule.

[0122] Abnormal state 5, the security state of the wireless relay device is abnormal.

[0123] In some embodiments, the abnormal security state of the wireless relay device includes: the identifier of the cell to which the control module of the wireless relay device is connected or resident is not in the preset cell list.

[0124] It should be noted that various preset values defined in the above abnormal types, such as preset thresholds (including the first preset threshold to the fourteenth preset threshold), preset ranges, and preset time schedules and other preset parameter values, are all pre-configured to the wireless relay device by the network-side node through signaling.

[0125] In some embodiments, the processing strategies for handling the abnormal state of the wireless relay device include the following:

[0126] Processing strategy 1, the first processing strategy for the connection abnormality between the control module and the wireless signal relay module.

[0127] In some embodiments, the first processing strategy includes at least one of the following:

[0128] The first self-processing strategy of the control module;

[0129] The control module generates and reports a first abnormal state report.

[0130] In some embodiments, the first self-processing strategy includes at least one of the following:

[0131] The control module turns off at least part of the antenna reflection array in the wireless signal relay module. For example, the control module turns off the wireless signal relay module; or, the control module turns off part of the antenna array in the wireless signal relay module;

[0132] The control module adjusts the wireless signal relay module to the standby state.

[0133] Exemplarily, when the connection anomaly between the control module and the wireless signal relay module is other than "connection interruption" and "failure of the switch (on / off) of the wireless signal relay module to switch", the control module can turn off the wireless signal relay module, or the control module can adjust the wireless signal relay module to a standby device. It can be understood that when the connection anomaly between the control module and the wireless signal relay module is other than "connection interruption" and "failure of the switch (on / off) of the wireless signal relay module to switch", the wireless signal relay module is in an uncontrollable state. Therefore, the wireless signal relay module can be turned off, or the wireless signal relay module can be adjusted to a standby state to avoid causing negative gain in coverage.

[0134] Exemplarily, when the connection anomalies between the control module and the wireless signal relay module include: "failure to configure the control codebook of part of the antenna reflection array" and "the value read back of the control codebook of the antenna reflection array of the wireless signal relay module is inconsistent with the configured value", the control module turns off part of the antenna arrays in the wireless signal relay module.

[0135] In some embodiments, the first anomaly status report includes at least one of the following: anomaly type, anomaly occurrence time (including the occurrence time of each anomaly type), first anomaly value, and operation log of the wireless relay device.

[0136] Wherein, the first anomaly value includes at least one of the following:

[0137] Packet error rate or packet loss rate;

[0138] The range of the antenna reflection array corresponding to the control codebook with configuration failure;

[0139] Panel attitude adjustment feedback value of the wireless signal relay module;

[0140] Value read back of the control codebook of the antenna reflection array of the wireless signal relay module;

[0141] Identifications of at least part of the antenna reflection arrays that are turned off.

[0142] Processing strategy 2, the second processing strategy for the connection anomaly between the first node and the control module.

[0143] In some embodiments, the second processing strategy includes at least one of the following:

[0144] The first constraint strategy that the control module needs to follow when accessing the access network node;

[0145] The second self-processing strategy of the control module;

[0146] The control module generates and reports a second anomaly status report.

[0147] In some embodiments, the first constraint policy includes at least one of the following:

[0148] A list of first target cells allowed by the control module for access or reselection;

[0149] The priority of the target cells allowed by the control module for access or reselection;

[0150] A list of second target cells allowed by the wireless signal relay module for relaying;

[0151] The number of access failure retry times of the control module;

[0152] The access failure retry time interval of the control module.

[0153] Exemplarily, in the case where the first constraint policy includes the list of first target cells, it indicates that when the control module accesses or reselects a cell, it only allows access to or reselection of the cells in the list of first target cells. It can be understood that when the wireless relay device is deployed, due to the limited range of the incident angle of the beam, the best source sites that the wireless relay device can serve are limited and preset. Therefore, if the control module of the wireless relay device accesses the wrong site, the coverage of the target blind area or weak area cannot be achieved.

[0154] Exemplarily, in the case where the first constraint policy includes the priority of the target cells allowed for access or reselection, when the number of sites that the wireless relay device can serve is greater than 1, the wireless relay device can be constrained to select the access service site according to the priority of the target cells allowed for access or reselection.

[0155] Exemplarily, in the case where the first constraint policy includes the list of second target cells, it indicates that the wireless signal relay module only allows relaying of the beams of the cells in the list of second target cells. It can be understood that since the wireless signal relay module can only achieve coverage of the blind area or weak area by relaying the beams of the correct cells, for the reflection module, even if the reflection module accesses the wrong cell, as long as the cell supports obtaining control information or beam switching instructions from the correct cell, the wireless signal relay module can still be guaranteed to relay the beams of the correct cells. Therefore, the above constraint policy only constrains the wireless signal relay module and does not limit the control module.

[0156] In some embodiments, as a network device supporting coverage improvement, the wireless relay device has more access failure retry times for its control module than those of ordinary terminal devices, so that the access reliability can be guaranteed.

[0157] In some embodiments, the second self - processing policy includes at least one of the following:

[0158] The control module turns off at least part of the antenna reflection array in the wireless signal relay module; for example, the control module turns off the wireless signal relay module; or, the control module turns off part of the antenna array in the wireless signal relay module;

[0159] The control module adjusts the wireless signal relay module to the standby state;

[0160] The control module reconnects to the network-side node and turns on the wireless signal relay module;

[0161] In the case where the cell accessed by the control module does not meet the first constraint policy, initiate access again according to the target cell provided by the first constraint policy;

[0162] The control module keeps the current working state and codebook of the wireless signal relay module unchanged;

[0163] The control module switches the codebook of the wireless signal relay module to the first preset codebook; wherein, the first preset codebook is used to adjust the direction of the outgoing beam of the wireless signal relay module, including: the first preset codebook is used to adjust the outgoing beam of the wireless signal relay module so that it points to the target area;

[0164] The control module switches the codebook of the wireless signal relay module to the second preset codebook; wherein, the second preset codebook is used to adjust the coverage range of the outgoing beam of the wireless signal relay module, including: the second preset codebook is used to adjust the coverage range of the outgoing beam of the wireless signal relay module so that it increases to the preset range.

[0165] Exemplarily, for any one or more of the above abnormal states 2, the control module can turn off the wireless signal relay module or adjust the wireless signal relay module to the standby state. It can be understood that this processing strategy belongs to a conservative strategy, that is, it is considered that each abnormal situation in abnormal state 2 means that the source signal reflected by the wireless signal relay module is abnormal.

[0166] Exemplarily, the above processing strategy of "the control module keeps the current working state and codebook of the wireless signal relay module unchanged" is applicable to scenarios where the codebook does not need to be adjusted frequently. In this way, even if the connection between the control module and the first node fails, the wireless signal relay module can maintain the current reflection state and will not cause additional negative gain.

[0167] Exemplarily, the processing strategy of "the control module switches the codebook of the wireless signal relay module to the first preset codebook" belongs to a compromise solution between "turning off the wireless relay device" and "maintaining the wireless relay device". That is, when the codebook of the wireless signal relay module is switched to the first preset codebook, the reflection direction and reflection beam of the wireless relay device can point to the target area, where the target area is a preset priority coverage area. The target area can be the safest area. When the reflection direction and reflection beam of the wireless signal relay device point to the target area, it can maintain the service to the UE as much as possible without causing additional negative gain.

[0168] Exemplarily, the processing strategy of "the control module switches the codebook of the wireless signal relay module to the second preset codebook" belongs to a compromise solution between "turning off the wireless relay device" and "maintaining the wireless relay device". That is, when the codebook of the wireless signal relay module is switched to the first preset codebook, the coverage range of the outgoing beam of the wireless signal relay module can be adjusted to increase it to a preset range. In this way, when the control module loses contact with the first node, the coverage performance of the wireless relay device for the blind area or weak area can be preferentially guaranteed.

[0169] In some embodiments, the second exception report includes at least one of the following: exception type, exception occurrence time (including the occurrence time of each exception type), second exception value, and operation log of the wireless relay device.

[0170] Among them, the second exception value includes at least one of the following:

[0171] Measured value of the abnormal beam arrival angle or beam arrival direction;

[0172] Frequency of wireless link failure;

[0173] Frequency of beam failure;

[0174] Number or frequency of failure of sending the status information of the wireless relay device, failure log;

[0175] Frequency of reselection failure;

[0176] Identifier of the resident cell;

[0177] Identifier of the accessed cell.

[0178] Exemplarily, the first node can identify from which direction the accessed wireless signal (or beam) comes according to the measured value of the abnormal beam arrival angle or beam arrival direction, and whether it conforms to the preset incident beam angle range when the wireless signal relay module is deployed. If it exceeds this range, the wireless signal relay module cannot achieve the coverage of the preset blind area.

[0179] Processing strategy 3, a third processing strategy for connection anomalies between the control module and the second node.

[0180] In some embodiments, the third processing strategy includes at least one of the following:

[0181] A first constraint strategy that the control module needs to follow when accessing the access network node;

[0182] The control module generates and reports a second anomaly status report;

[0183] A second self - processing strategy of the control module.

[0184] Processing strategy 4, a fourth processing strategy for anomalies of the control module or the wireless signal relay module.

[0185] In some embodiments, the fourth processing strategy includes at least one of the following:

[0186] A second constraint strategy that the control module or the wireless signal relay module needs to follow during operation;

[0187] A third self - processing strategy of the control module;

[0188] The control module generates and reports a third anomaly status report.

[0189] In some embodiments, the second constraint strategy includes at least one of the following:

[0190] The turn - on time, turn - off time, and standby time of the wireless signal relay module follow a preset schedule;

[0191] The turn - on time, turn - off time, standby time, and connection time of the control module follow a preset schedule.

[0192] It can be understood that the above - mentioned second constraint strategy is applicable to scenarios where the operator of the wireless relay device has a busy - time / idle - time plan for the working state of the wireless relay device, which is beneficial to the energy saving of the wireless relay device. If the operation of the wireless signal relay module or the control module does not conform to the above - mentioned preset schedule, a status report is reported, where the status may include the operation log records of the time period that does not conform to the preset schedule.

[0193] In some embodiments, the third self - processing strategy includes at least one of the following:

[0194] The control module turns off at least part of the antenna reflection array in the wireless signal relay module. For example, the control module turns off the wireless signal relay module; or, the control module turns off part of the antenna array in the wireless signal relay module;

[0195] The control module adjusts the wireless signal relay module to the standby state.

[0196] Exemplarily, in the case where the operating state of the control module or the wireless signal relay module is abnormal, it means that the components of the wireless relay device are potentially damaged, and maintaining the operation of the wireless relay device may bring additional negative gain. Therefore, the control module can turn off the wireless signal relay module.

[0197] Exemplarily, in the case where the operating voltage or standby voltage of some antenna elements or antenna units of the antenna reflection array is abnormal, the control module can turn off some antenna arrays in the wireless signal relay module.

[0198] Exemplarily, in the case where the standby voltage or standby power consumption of the control module or the wireless signal relay module exceeds a preset range, the control module can adjust the wireless signal relay module to the standby state.

[0199] In some embodiments, the third abnormal state report includes at least one of the following: abnormal type, abnormal occurrence time (including the occurrence time of each abnormal type), third abnormal value, and operation log of the wireless relay device.

[0200] Wherein, the third abnormal value includes at least one of the following: voltage, power consumption, charging power, remaining power or remaining working time, identifier of the antenna reflection array with abnormal voltage, and identifier of the antenna reflection array that is turned off.

[0201] Processing strategy 5, the fifth processing strategy for the abnormal security state of the wireless relay device.

[0202] In some embodiments, the fifth processing strategy includes at least one of the following:

[0203] Connection constraint strategy, that is, the constraint strategy that the control module needs to follow when accessing the access network node. Exemplarily, the connection constraint strategy includes: the list of first target cells allowed to be accessed or reselected by the control module;

[0204] In the case where the cell accessed by the control module does not belong to the cells in the list of first target cells, initiate access to the cells in the list of first target cells again.

[0205] In some embodiments, the above step S201 can be implemented as: receiving the processing strategy for processing the abnormal state of the wireless relay device sent by the second node.

[0206] It can be understood that the above processing strategy can be formulated by the second node according to the abnormal state of the wireless relay device and sent to the first node. Exemplarily, the second node can be the management entity of the wireless relay device.

[0207] S202. The first node sends the processing strategy to the wireless relay device; correspondingly, the wireless relay device receives the processing strategy for processing the abnormal state of the wireless relay device sent by the first node.

[0208] It can be understood that, based on the exception handling method provided in the embodiments of the present application, the first node determines a processing strategy for handling the abnormal state of the wireless relay device and sends the processing strategy to the wireless relay device; correspondingly, the wireless relay device receives the processing strategy sent by the first node for handling the abnormal state of the wireless relay device. In this way, the wireless relay device can perform real-time management of its own working state, and then, when an abnormal state occurs, it can perform self-processing according to the processing strategy, which can improve the control robustness and working reliability of the wireless relay device to achieve stable and high-quality coverage of the mobile terminal.

[0209] In some embodiments, after the above step S202, as Figure 5 shown, the method further includes the following steps S301 - S302.

[0210] S301. The wireless relay device detects the working state of the wireless relay device.

[0212] It can be understood that, based on the method provided in the embodiments of the present application, the wireless relay device can perform real-time management of its own working state, and then, when an abnormal state occurs, it can perform self-processing according to the processing strategy, which can improve the control robustness and working reliability of the wireless relay device to achieve stable and high-quality coverage of the mobile terminal.

[0213] In some embodiments, as Figure 6 shown, the above method further includes the following steps S401 - S403.

[0214] S401. The wireless relay device detects the working state of the wireless relay device.

[0215] S402. When an abnormal state occurs in the wireless relay device, the wireless relay device generates an abnormal state report.

[0217] S403. The wireless relay device sends the abnormal state report to the first node. Correspondingly, the first node receives the abnormal state report sent by the wireless relay device.

[0218] In some embodiments, after the above step S403, the method further includes: the first node sends the abnormal state report of the wireless relay device to the second node.

[0219] In some embodiments, the above method further includes: when a connection anomaly between the first node and the control module is detected, the first node sends a status report of the connection anomaly between the first node and the control module to the second node.

[0220] It can be understood that, based on the method provided in the embodiments of the present application, the wireless relay device can manage its own working state in real time, and when an abnormal state occurs, send an abnormal state report to the first node in a timely manner to inform the first node. In this way, the first node can handle the abnormal state to ensure the working reliability of the wireless relay device.

[0221] For ease of understanding, the following uses examples to illustrate the abnormal handling method provided in the embodiments of the present disclosure.

[0222] It should be noted that in the following examples, the first node is a wireless communication base station (abbreviated as base station), the wireless relay device is a RIS, the control module of the wireless relay device is a RIS-MT, the wireless signal relay module of the wireless relay device is a RIS-Fwd, and the second node is the management entity of the RIS. Among them, the management entity of the RIS can manage the RIS through the base station and is responsible for formulating an abnormal handling strategy for the RIS. The RIS-MT can communicate with the base station, receive control information from the base station, report the status information of the RIS to the base station and the management entity of the RIS, and control the operation of the RIS-Fwd.

[0223] In the following examples, an application scenario where the RIS is deployed within the coverage area of the base station is used for illustration.

[0224] Example 1. An abnormal handling method for a connection anomaly between the RIS-MT and the RIS-Fwd.

[0225] Exemplarily, as Figure 7 shown, in Example 1, the above method can be implemented as the following steps:

[0227] Sa2. The base station performs identity recognition on the access terminal (i.e., the RIS-MT) and identifies that the device type of the access terminal is a RIS device.

[0228] Exemplarily, the base station can perform identification based on the core network subscription information of the RIS device; or, the base station can perform identification in combination with the capability information reported by the RIS-MT.

[0229] Sa3. The base station sends an abnormal handling strategy to the RIS-MT.

[0230] Among them, the exception handling strategy is the first handling strategy for connection exceptions between RIS-MT and RIS-Fwd. Exemplarily, the first handling strategy includes one or more of the following:

[0253] At the same time, RIS-MT maintains the monitoring of RIS-Fwd.

[0254] Sa6. RIS-MT determines whether an abnormality occurs between RIS-MT and RIS-Fwd.

[0255] Exemplarily, after RIS-MT sends the control information of RIS-Fwd to RIS-Fwd and does not receive the confirmation feedback information of RIS-Fwd, it is confirmed that the connection between RIS-MT and RIS-Fwd is interrupted.

[0256] Exemplarily, after RIS-MT sends the control information of RIS-Fwd to RIS-Fwd and the readback value of the codebook received is inconsistent with the configured value, it is confirmed that the connection between RIS-MT and RIS-Fwd is interrupted.

[0260] Exemplarily, if it is identified that the codebook readback value is inconsistent with the configured value, RIS-Fwd can be selected to be turned off or put on standby.

[0261] Exemplarily, if it is identified that the panel attitude of RIS-Fwd is not in place, RIS-Fwd can be selected to be turned off or put on standby, or an abnormal status report can be generated and reported to the network side node, and the network side node decides whether to turn off RIS-Fwd or select other ways to adjust the RIS beam (such as switching the control codebook of the antenna reflection array of RIS-Fwd).

[0262] Sa8. RIS-MT generates a first abnormal status report and sends it to the base station.

[0263] Exemplarily, RIS-MT generates a first abnormal status report according to the identified abnormal type, the occurrence time and / or duration of each abnormal type, and the first abnormal value.

[0270] Exemplarily, the management entity of the RIS can be based on the core network subscription information of the RIS device; or, the management entity of the RIS can perform recognition in combination with the capability information reported by RIS-MT; or, the management entity of the RIS can perform recognition according to the saved RIS device registration information.

[0271] Sb4. The management entity of the RIS sends an abnormal handling strategy to the base station.

[0272] Sb5. The base station sends an exception handling policy to the RIS-MT.

[0293] Exemplarily, the connection anomaly between the base station and the RIS-MT includes at least one of the following anomaly types:

[0294] The angle of arrival or direction of arrival of the beam measured by the RIS-MT exceeds the first preset range; wherein, the angle of arrival of the beam refers to the angle when the beam transmitted by the base station reaches the antenna panel of the RIS-Fwd; the direction of arrival of the beam refers to the direction when the beam transmitted by the base station reaches the antenna panel of the RIS-Fwd;

[0295] The radio link between the base station and the RIS-MT is abnormal;

[0306] The transmission of control information sent by the base station to the RIS-MT fails;

[0307] The transmission of status information sent by the RIS-MT to the base station fails.

[0308] It should be noted that the above various abnormal types can be indicated in the second processing strategy; or, the above various abnormal types are pre-configured for the RIS; or, the above various abnormal types can be pre-agreed with the RIS.

[0309] The above preset threshold can be configured in the second processing strategy; or, the above preset threshold can be pre-configured for the RIS through other signaling.

[0310] Sb6. The RIS-MT receives the RIS control information sent by the base station.

[0313] Meanwhile, the RIS-MT keeps monitoring the RIS-Fwd.

[0314] Sb8. The RIS-MT and the base station respectively detect that the communication link connection between the RIS-MT and the base station is abnormal.

[0315] It can be understood that the RIS-MT and the base station can respectively monitor the communication link between them and determine whether the communication link connection between the RIS-MT and the base station is abnormal.

[0316] Exemplarily, in the case of a radio link failure, it is determined that the connection between the RIS-MT and the base station is abnormal.

[0317] Exemplarily, in the case of a beam failure, it is determined that the connection between the RIS-MT and the base station is abnormal.

[0318] Exemplarily, in the case that the cell accessed by the RIS-MT is not a high-priority cell or a preset target cell, it is determined that the connection between the RIS-MT and the base station is abnormal.

[0319] Sb9. When the base station detects a communication link failure between the RIS-MT and the base station, it generates a status report of the abnormal connection between the RIS-MT and the base station and sends it to the management entity of the RIS.

[0320] When Sb10 and RIS-MT detect a communication link failure between RIS-MT and the base station, RIS-MT performs self-processing according to the second processing strategy.

[0321] Exemplarily, if a radio link failure is detected and the target cell provided by the above first constraint strategy cannot be accessed, turn off RIS-MT, or switch the codebook of RIS-Fwd to the first preset codebook or the second preset codebook.

[0322] Exemplarily, if the cell accessed by RIS-MT does not meet the connection to the above first constraint strategy, initiate access again according to the target cell provided by the first constraint strategy.

[0323] Exemplarily, if a beam failure occurs, record the failure times, occurrence time, beam measurement values, etc., and generate an exception status report.

[0324] It should be noted that the embodiments of the present application do not limit the execution order of the above steps Sb9 and Sb10. For example, Sb9 can be executed first, and then Sb10; or Sb10 can be executed first, and then Sb9; or Sb9 and Sb10 can be executed simultaneously.

[0325] Sb11. After RIS-MT successfully reconnects to the base station, upload the exception status report of RIS.

[0326] Sb12. The base station forwards the exception status report of RIS to the management entity of RIS.

[0327] Example 3. An exception handling method for the connection exception between the management entity of RIS and RIS-MT.

[0328] It can be understood that usually the management entity of RIS is connected to RIS through the base station. When the connection between the management entity of RIS and RIS is abnormal, most likely there is a problem with the air interface connection between the base station and RIS. Therefore, for the exception handling method of the connection exception between the management entity of RIS and RIS-MT in Example 3, reference can be made to the exception handling method for the connection exception between the base station and RIS-MT in Example 2 above.

[0329] Example 4. An exception handling method for RIS-MT or RIS-Fwd exception.

[0354] In some embodiments, the RIS-Fwd anomalies include at least one of the following:

[0355] The standby voltage or standby power consumption exceeds the tenth preset threshold;

[0356] The operating voltage or operating power consumption exceeds the eleventh preset threshold;

[0360] The remaining battery level or remaining operating time is lower than the fourteenth preset threshold;
